Description

Technical Field

[0001] This utility model relates to the field of railway engineering equipment and construction technology, and in particular to an auxiliary device for pouring monolithic concrete track bed for railway lines. Background Technology

[0002] When pouring concrete monolithic track bed inside a factory, concrete pump trucks are typically used to complete the pouring work. Currently, the most common concrete pump trucks on the market are divided into two types: boom pump trucks and ground pumps (trailer pumps), each with its own advantages and disadvantages.

[0003] Boom pump trucks exhibit significant advantages during operation. They offer excellent operational flexibility, enabling convenient pouring operations and precise control over the amount of concrete poured in each area. Furthermore, their relatively fast pouring speed contributes to improved construction efficiency. However, boom pump trucks also present some significant drawbacks. Firstly, their maintenance and operating costs are higher, increasing overall construction costs. Secondly, the limited operating height of boom pump trucks imposes stringent requirements on the construction site, which to some extent restricts their application scope.

[0004] Trailer pumps (also known as ground pumps) are mobile, equipped with tires, and can be towed to the work site by a tractor, facilitating construction in different locations. However, their delivery speed is relatively slow, which can affect construction progress. More importantly, in situations with limited factory height or traffic restrictions, boom pump trucks cannot be used for pouring, and the slow delivery speed of trailer pumps makes them prone to blockages. Once a blockage occurs, the delivery pipe needs to be cleaned, which not only consumes a lot of time and manpower but also easily contaminates equipment inside the factory, causing additional trouble and losses to the construction.

[0005] Besides using concrete pump trucks, there have been attempts to use concrete mixer trucks for direct pouring. However, due to the special structure of the railway track bed, with two rails separating it and continuous sleepers and steel mesh underneath, the flow of concrete is hindered. To complete the pouring work, a large amount of labor is required, using shovels to transfer the concrete to the center of the track and to the other side of the sleepers where direct pouring is not possible. This construction method is not only labor-intensive but also inefficient.

[0006] In view of the many problems existing in the above-mentioned casting methods, in order to achieve efficient and convenient construction of the integral track bed in the factory, there is an urgent need for an auxiliary device that can move flexibly on the upper part. Summary of the Invention

[0007] This utility model provides an auxiliary trolley for pouring integral concrete track bed for railway lines. This auxiliary trolley can efficiently and flexibly perform precise pouring of three areas: two small areas on each side of the integral track bed and one large area in the center. This meets the actual needs of integral track bed pouring construction in the plant and solves the problems existing in the current pouring method for integral track bed pouring construction in the plant.

[0008] To solve the above problems, the technical solution adopted by this utility model is: It includes a support frame with support wheels at the bottom. An inclined receiving plate is located at the top of the support frame along the width of the monolithic concrete track bed of the railway line. The receiving plate includes a receiving plate frame with two longitudinal partitions dividing it into three blank areas. Each area has a corresponding movable door. One end of each movable door is hinged to the receiving plate frame via a hinge, and the other end is connected to the receiving plate frame via a buckle. Both the hinge and the buckle are installed below the bottom of the receiving plate.

[0009] A more specific technical solution than the above-mentioned technical solution is that baffles are provided on both sides of the receiving plate.

[0010] Furthermore, the higher end of the movable door is hinged to the receiving plate frame via a hinge, and the lower end of the movable door is hinged to the receiving plate frame via a snap fastener.

[0011] Furthermore, the hinge is a hinge.

[0012] Furthermore, the buckle is installed on the receiving plate frame.

[0013] Furthermore, the support wheel is a support wheel pair.

[0014] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art: 1. This utility model uses a support frame as the main structure, with support wheels installed at the bottom to ensure the stable movement of the trolley on the railway line. An inclined receiving plate is set at the top of the support frame. The receiving plate is divided into three blank areas by two longitudinal partitions. Each area corresponds to a specific pouring part of the overall track bed. This design, combined with the movable door that works with it, allows the trolley to receive and pour concrete into the target area according to a predetermined path. This effectively solves the problem that existing pouring methods cannot fully and accurately cover different areas, fully meets the actual needs of the overall track bed pouring construction in the plant, and improves the quality and integrity of the pouring work.

[0015] 2. The support wheel of this utility model provides stable support and flexible mobility, making it easy for construction personnel to move the auxiliary trolley to different positions for pouring operations according to the construction progress and needs, thereby improving the flexibility and efficiency of construction.

[0016] 3. The material receiving plate of this utility model is equipped with baffles on both sides, which effectively prevents concrete from spilling from both sides during the pouring process, reduces concrete waste, ensures the cleanliness of the construction site, and also helps to improve the utilization rate of concrete and reduce construction costs.

[0017] 4. In this utility model, the higher end of the movable door is hinged to the receiving plate frame via a hinge (such as a hinge), and the lower end is connected to the receiving plate frame via a buckle, which is installed on the receiving plate frame. This design allows the movable door to remain closed naturally under the action of gravity. When it needs to be opened, simply release the buckle. The operation is simple and labor-saving, further improving the convenience of construction.

[0018] 5. This utility model solves the problems of existing pump trucks: ① Overcoming the limitations of boom pump trucks: Although boom pump trucks are flexible in operation and have a fast pouring speed, they have high maintenance and usage costs, are limited by operating height, and have stringent requirements for construction sites; This utility model is not strictly limited by operating height and site, reduces construction costs, broadens the scope of application, and can play a stable role under different site conditions. ② Improvement of shortcomings of ground pumps: Ground pumps are mobile but have slow delivery speeds, making them unusable when factory height is limited or vehicle access is restricted. They are also prone to clogging, and cleaning the delivery pipes after clogging consumes a lot of time and manpower, and can also contaminate factory equipment. This utility model avoids the problems of slow delivery speed and easy clogging of ground pumps, reduces the extra trouble and losses caused by clogging, improves construction efficiency, and ensures a clean construction environment.

[0019] 6. This utility model optimizes the direct pouring method using a concrete mixer truck: When using a concrete mixer truck for direct pouring, the flow of concrete is obstructed due to the special structure of the railway track bed, requiring a large amount of labor to transfer the concrete with shovels, which is labor-intensive and inefficient; This utility model changes this inefficient construction method, and through reasonable design, makes the concrete pouring process smoother, reduces labor intensity, and significantly improves construction efficiency.

[0023] Figure 4 This is a diagram illustrating the application scenario of this utility model.

Detailed Implementation

[0025] The present invention will be further described in detail below with reference to the accompanying drawings: Example

[0026] like Figures 1-4 The illustrated auxiliary trolley for pouring monolithic concrete track bed for railway lines includes a support frame 1. Support wheels 2 are located at the bottom of the support frame 1. The design of the support wheels 2 allows the trolley to move flexibly along the monolithic concrete track bed 7 of the railway line, adapting to the pouring needs of different locations. When pouring monolithic concrete track bed 7 within the factory, construction workers can easily move the trolley to different pouring positions according to the construction progress and needs, eliminating the need for time and manpower spent on equipment transportation and reinstallation. For example, after completing the pouring of one area, construction workers only need to push the trolley along the rails of the monolithic concrete track bed 7 to the next pouring position to continue the pouring operation, greatly shortening the construction cycle and improving overall construction efficiency. Simultaneously, during movement, the trolley maintains a stable trajectory through the contact between the support wheels 2 and the rails of the monolithic concrete track bed 7. When reaching the designated pouring position, the trolley achieves precise positioning through the braking mechanism of the support wheels 2 or in conjunction with other positioning devices, ensuring that the concrete is accurately poured into the target area.

[0027] An inclined receiving plate 3 is provided at the top of the supporting frame 1 along the width direction of the monolithic concrete track bed 7 of the railway line. The receiving plate 3 includes a receiving plate frame 3-1, and two longitudinal partitions 3-2 are provided inside the receiving plate frame 3-1, dividing the receiving plate frame 3-1 into three blank areas. Each area corresponds to a specific pouring position of the monolithic concrete track bed 7 of the railway line. At the same time, each area is provided with a corresponding movable door 3-3. This design allows the trolley to receive and transport the concrete to the target area according to a predetermined path, thereby effectively solving the problem that existing pouring methods cannot fully and accurately cover different areas, fully meeting the actual needs of the pouring construction of the monolithic concrete track bed 7 of the railway line in the plant, and improving the quality and integrity of the pouring work.

[0028] One end of the movable door 3-3 is hinged to the receiving plate frame 3-1 via hinge 4, and the other end is connected to the receiving plate frame 3-1 via latch 5. Both hinge 4 and latch 5 are installed below the bottom of the receiving plate 3. This design makes the opening and closing of the movable door 3-3 very convenient. When a certain area needs to be poured, the construction workers can quickly release latch 5, open the movable door 3-3, and let the concrete flow into the target area; after the pouring is completed, the latch 5 can be quickly fastened to close the movable door 3-3, preventing the concrete from continuing to flow out or overflow. Compared with the traditional pouring method, which requires a large amount of labor to move the concrete with shovels, this design significantly improves construction efficiency.

[0029] Based on the above technical solution, a further technical solution could be: baffle plates 6 are provided on both sides of the receiving plate 3. The baffle plates 6 effectively prevent concrete from spilling from both sides during the flow process. As the concrete slides down the receiving plate 3 and flows into various areas, the baffle plates 6 act as a barrier and guide, ensuring that the concrete accurately enters the target area without overflowing to other parts. For example, during the pouring process, if the concrete flows quickly or is affected by external forces, splashing or overflow may occur. The presence of the baffle plates 6 can avoid this phenomenon, ensuring the cleanliness of the construction site and the accuracy of the pouring.

[0030] Furthermore, the higher end of the movable door 3-3 is hinged to the receiving plate frame 3-1 via hinge 4, while the lower end of the movable door 3-3 is hinged to the receiving plate frame 3-1 via latch 5. This design allows the movable door 3-3 to remain closed naturally under gravity. When it needs to be opened, simply release the latch 5, making the operation simple and effortless.

[0031] Furthermore, hinge 4 is a hinge.

[0032] Furthermore, the clip 5 is installed on the receiving plate frame 3-1.

[0033] Support wheel 2 is a support wheel pair. This design can increase the contact area between support wheel 2 and the rail, reduce the bumps and swaying of the trolley during movement, and improve the accuracy of pouring.

[0034] It should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
