濟南瀝青混凝土攤鋪機械的合理選配

來源:http://m.yuanchuodian.cn/ 日期:2023-12-23

機械設備是機械化施工的物質基礎。瀝青混凝土攤鋪機是鋪筑瀝青混凝土路面必不可少的重要工具,其本身的性能及操作對攤鋪平整度的影響很大。同時,攤鋪機結構參數不穩定、行走裝置打滑、攤鋪機攤鋪速度的快慢不勻、機械猛烈起步和緊急制動以及供料速度的忽快忽慢等,都會造成面層的不平整。攤鋪機廠家介紹了瀝青混凝土攤鋪機的選型要求及相應的攤鋪機結構參數的調整與選用。

Mechanical equipment is the material foundation of mechanized construction. Asphalt concrete paver is an essential tool for laying asphalt concrete pavement, and its performance and operation have a significant impact on the smoothness of paving. At the same time, unstable structural parameters of the paver, slipping of the walking device, uneven paving speed of the paver, violent mechanical starting and emergency braking, and fluctuating feeding speed can all cause unevenness in the surface layer. The paver manufacturer introduced the selection requirements for asphalt concrete pavers and the corresponding adjustment and selection of paver structural parameters.

1 瀝青混凝土攤鋪機的選型

Selection of asphalt concrete paver

攤鋪機的選配要考慮機械設備之間的能力匹配。就攤鋪質量而言,攤鋪作業速度是否均勻、攤鋪

The selection of pavers should consider the ability matching between mechanical equipment. In terms of paving quality, whether the paving operation speed is uniform and whether the paving

作業是否連續、攤鋪寬度及厚度能否滿足工藝要求等,都是選擇攤鋪機時必須考慮的問題。攤鋪作業

Whether the homework is continuous, and whether the paving width and thickness can meet the process requirements are all issues that must be considered when choosing a paving machine. Paving operation

速度的均勻連續,主要取決于攤鋪機的有效攤鋪能力與拌和設備的實際拌和能力是否匹配,而攤鋪能

The uniform and continuous speed mainly depends on whether the effective paving capacity of the paver matches the actual mixing capacity of the mixing equipment, and paving can

力又是由攤鋪作業速度、一次鋪筑寬度、厚度以及瀝青混凝土碾壓密實度決定的。這就要求在選擇攤鋪機時,要綜合考慮道路的設計寬度、攤鋪密實厚度、攤鋪機作業速度的可調范圍以及找平、分料效果。

The strength is determined by the speed of paving operation, the width and thickness of a single paving, and the compactness of asphalt concrete compaction. This requires that when selecting a paver, comprehensive consideration should be given to the design width of the road, the compacted thickness of the paving, the adjustable range of the paver's operating speed, and the leveling and material distribution effects.

(1)根據道路的設計寬度、攤鋪工藝及攤鋪質量等要求,綜合選擇瀝青混凝土攤鋪機的攤鋪

(1) Based on the requirements of road design width, paving technology, and paving quality, a comprehensive selection of asphalt concrete pavers is made for * * paving

寬度、**攤鋪厚度、攤鋪速度、攤鋪機的生產率、攤鋪成型精度和攤鋪成型質量等。即充分考慮瀝青混凝土攤鋪機的主參數和基本參數滿足工程設計的要求,并且與瀝青混凝土攪拌設備的生產率相配套。

Width, paving thickness, paving speed, productivity of the paver, paving forming accuracy, and paving forming quality. Fully consider the main and basic parameters of the asphalt concrete paver to meet the requirements of engineering design, and match the productivity of the asphalt concrete mixing equipment.

(2)履帶式瀝青混凝土攤鋪機具有較長的接地長度,接地面積大、接地比壓小,對不平整的路面適

(2) The tracked asphalt concrete paver has a longer grounding length, a larger grounding area, and a smaller grounding pressure, making it suitable for uneven road surfaces

應性好,在稍作預壓實的不平整路面上即可進行高質量的攤鋪。采用專用的柔性橡膠履帶,靜摩擦力

Good adaptability, high-quality paving can be carried out on slightly pre compacted uneven road surfaces. Adopting specialized flexible rubber tracks with static friction force

和整機質量較大,使履帶式瀝青混凝土攤鋪機具有更大的牽引力,可在各種路面上進行攤鋪作業,也可

The larger overall weight of the machine gives the tracked asphalt concrete paver greater traction, allowing for paving operations on various road surfaces, as well as

在高低不平的道路上高速平穩行駛,具有行駛噪聲低、速度快等特點。

Driving at high speed and smoothly on uneven roads has the characteristics of low driving noise and fast speed.

(3)輪胎式瀝青混凝土攤鋪機具有良好的機動性,轉移方便,但在路基較差的情況下易打滑。在前

(3) The tire type asphalt concrete paver has good maneuverability and is easy to transfer, but it is prone to slipping in poor roadbed conditions. Before

轉向輪加裝具有同步與差速控制功能的獨立液壓驅動機構,可使前輪既驅動又轉向,能在攤鋪作業時提高牽引力,有效地防止攤鋪機打滑,而在攤鋪機高速行駛時還可使前轉向輪不驅動。

The installation of an independent hydraulic drive mechanism with synchronization and differential control functions on the steering wheel can enable the front wheels to drive and turn, improve traction during paving operations, effectively prevent the paver from slipping, and also prevent the front steering wheel from being driven when the paver is traveling at high speed.

(4)采用電子控制裝置控制液壓泵,使其按電位器預先設定的行駛和轉向數值供給所需流量。速

(4) Using an electronic control device to control the hydraulic pump, it supplies the required flow rate according to the predetermined driving and steering values of the potentiometer. speed

度傳感器能不間斷地檢測實際速度值,并通過電信號傳遞給電子控制裝置,再與電位器裝置自動改變

The degree sensor can continuously detect the actual speed value and transmit it to the electronic control device through an electrical signal, which then automatically changes with the potentiometer device

變量泵的流量,以符合設定的行駛速度。即使在超載的情況下,也能按預選的速度行駛,因而能夠獲得

The flow rate of the variable pump should meet the set driving speed. Even in case of overload, it can still drive at the pre-selected speed, thus obtaining

很高的攤鋪質量。

High paving quality.

(5)行駛系統備有一套應急控制裝置,可保證在電子控制裝置或速度傳感器出現故障時仍可以繼

(5) The driving system is equipped with an emergency control device, which can ensure that in the event of a malfunction in the electronic control device or speed sensor, it can still continue to operate

續作業。

Continuation of homework.

(6)除配置標準的熨平板外,還可以根據施工需要選擇其他規格的熨平板。此外,電子調平裝置、

(6) In addition to standard ironing plates, other specifications of ironing plates can also be selected according to construction needs. In addition, electronic leveling devices

調平梁、拖管、基準線支架、45°切邊靴等附件也可根據施工情況選擇。

Accessories such as leveling beams, towing pipes, baseline brackets, and 45 ° edge cutting shoes can also be selected according to the construction situation.

2 瀝青混凝土攤鋪機結構參數的調整

Adjustment of structural parameters of asphalt concrete paver

瀝青混凝土攤鋪機結構參數是指熨平板的寬度、拱度、工作角、螺旋分料器的長度及位置、振搗器和振動器的振幅、頻率等。當同一臺攤鋪機選用了不同的結構參數時,所鋪筑出的攤鋪層的性質就不同。因此,合理地調整與選用各結構參數值,是保證攤鋪層均勻一致、平整密實的重要前提。

The structural parameters of asphalt concrete paver refer to the width, arch, working angle of the ironing plate, length and position of the spiral distributor, amplitude and frequency of the vibrator and vibrator, etc. When the same paver uses different structural parameters, the properties of the paving layer it lays will be different. Therefore, reasonable adjustment and selection of various structural parameter values is an important prerequisite to ensure the uniformity, flatness, and compactness of the paving layer.
