Description

Technical Field

[0001] This utility model relates to the field of railway construction material transportation technology, and in particular to a short-distance railway construction material transportation vehicle. Background Technology

[0002] In railway construction, short-distance material transportation is a crucial aspect. Railway construction sites are typically characterized by complex terrain and dispersed work areas, necessitating frequent transport of various construction materials, such as sand, gravel, cement, and steel, between different locations. These materials play a fundamental supporting role in the smooth progress of railway projects, and their transportation efficiency and safety directly impact the overall construction schedule and quality. Currently, while some transportation equipment exists for short-distance railway construction materials, most suffer from cumbersome operation and unstable protective performance. Traditional transportation equipment is often simply designed, lacking sufficient consideration for different construction scenarios and material characteristics, making it difficult to meet the increasingly diverse and efficient demands of railway construction.

[0003] Some existing short-distance railway construction material transport vehicles require operators to complete multiple complex steps to adjust the protective devices during operation. For example, some transport vehicles use traditional methods to fix the protective plates, requiring tools to remove or install bolts to move the plates. This not only increases the workload of operators but also consumes a significant amount of time and energy. Under the tight pace of railway construction, this cumbersome operating procedure can severely impact the efficiency of material transportation, leading to delays in construction progress.

[0004] Protective performance is one of the key indicators for railway construction material transport vehicles. However, some transport vehicles on the market currently have significant deficiencies in terms of protective stability. The protective devices on some vehicles are easily loosened or displaced during material transport due to vehicle shaking and bumps, failing to effectively prevent materials from slipping off the sides. This not only wastes materials and increases construction costs but may also pose a threat to the safety of personnel and equipment at the construction site.

[0005] The terrain and operational needs at railway construction sites are highly variable, and the requirements for material transportation also differ at different construction stages. However, existing transport vehicles have relatively fixed structures, lack flexibility and adjustability, and are difficult to adapt to diverse construction scenarios and the transportation needs of materials of different sizes and weights. Therefore, we have provided a short-distance transport vehicle for railway construction materials. Utility Model Content

[0006] To address the aforementioned problems, this utility model proposes a short-distance railway construction material transport vehicle, which more accurately solves the problems mentioned in the background art.

[0007] This utility model is achieved through the following technical solution:

[0008] The utility model proposes a short-distance transport vehicle for railway construction materials, including a bearing plate, a pusher frame and casters. The pusher frame is fixedly installed on the upper surface of the bearing plate, and the casters are fixedly installed on the lower surface of the bearing plate. A rectangular through groove is opened through the side of the bearing plate, and an L-shaped protective plate is inserted into the inner wall of the rectangular through groove to prevent materials from falling to the side.

[0009] A reset structure is connected between the rectangular through groove and the L-shaped protective plate;

[0010] A limit assembly is connected between the support plate and the L-shaped protective plate;

[0011] The limiting component includes a limiting insertion hole on the end surface of the L-shaped protective plate and a strip groove on the side of the bearing plate. A horizontal fixing rod is fixedly connected between the two end walls of the strip groove. A spring is sleeved around the horizontal fixing rod. A movable sleeve block is slidably sleeved around the horizontal fixing rod. A fixing block is fixedly connected to the surface of the movable sleeve block. A limiting insertion rod is fixedly connected to one end of the fixing block.

[0012] Furthermore, the reset structure includes a strip-shaped groove formed on the inner wall of the rectangular through groove. A fixing rod is fixedly connected between the two end walls of the strip-shaped groove. A spring is sleeved around the fixing rod. A sliding sleeve block is slidably sleeved around the fixing rod. The sliding sleeve block is slidably connected to the inner wall of the strip-shaped groove, and the opposing surfaces of the two sliding sleeve blocks are fixedly connected to the two end surfaces of the L-shaped protective plate.

[0013] Furthermore, the movable sleeve is slidably connected to the inner wall of the strip groove, and the surface of the fixed block is provided with a sliding groove for applying external force to generate lateral movement of the fixed block.

[0014] Furthermore, one end of the limiting rod is inserted into the inner wall of the limiting hole, and the inner diameter of the limiting hole is compatible with the outer diameter of the limiting rod.

[0015] Furthermore, one end of the second spring is fixedly connected to the end wall of the strip groove, and the other end of the second spring is fixedly connected to one end surface of the movable sleeve block.

[0016] Furthermore, one end of the spring is fixedly connected to the end wall of the strip groove, and the other end of the spring is fixedly connected to one end surface of the sliding sleeve block.

[0017] The beneficial effects of this utility model are:

[0018] This invention achieves a perfect combination of ease of operation and protective stability through its designed limiting components and reset structure. Regarding ease of operation, the sliding groove on the surface of the fixing block provides operators with an extremely convenient interface. When the L-shaped protective plate needs to be moved for loading and unloading materials, the operator simply inserts their finger into the sliding groove and applies external force to cause the fixing block to slide, thereby disengaging the limiting rod from the limiting hole. At this point, the L-shaped protective plate can move freely, eliminating the need for complex and cumbersome operating procedures, greatly saving time and labor costs, and improving work efficiency.

[0019] This invention connects the L-shaped protective plate with a rectangular through-slot, a reset structure, and a limiting component, allowing the plate to not only move and adjust its position flexibly according to actual needs, but also to be quickly and stably fixed after adjustment via the limiting component. This flexibility enables the transport vehicle to adapt to the transportation of materials of different sizes and shapes. Attached Figure Description

Detailed Implementation

[0027] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will further explain this utility model.

[0028] Example

[0029] like Figures 1-6 As shown in the figure, an embodiment of this utility model discloses a short-distance transport vehicle for railway construction materials, mainly composed of a bearing plate 1, a push frame 2, and casters 3. The push frame 2 is firmly fixed to the upper surface of the bearing plate 1 by welding, so that the operator can easily push the transport vehicle. The casters 3 are fixed to the lower surface of the bearing plate 1 by bolt connection, so that the transport vehicle can move flexibly on the railway construction site. A rectangular through groove 4 is cut through the side of the bearing plate 1. The size of the rectangular through groove 4 is determined according to actual needs to ensure that an L-shaped protective plate 5 can be smoothly inserted. The size of the L-shaped protective plate 5 is adapted to the rectangular through groove 4. When it is inserted from one side of the rectangular through groove 4, the L-shaped protective plate 5 can move to a certain extent within the rectangular through groove 4. When materials are placed on the transport vehicle, the L-shaped protective plate 5 can effectively prevent the materials from slipping off the side of the bearing plate 1 during transportation. A reset structure is connected between the rectangular through groove 4 and the L-shaped protective plate 5. This reset structure can automatically reset the L-shaped protective plate 5 after it moves. Simultaneously, a limiting assembly is connected between the support plate 1 and the L-shaped protective plate 5. The limiting assembly specifically includes: a limiting insertion hole 10 on the end surface of the L-shaped protective plate 5, the position and size of which are determined according to the design of the subsequent limiting rod 16; a strip-shaped groove 11 on the side of the support plate 1, the length and width of which must meet the installation requirements of each component of the limiting assembly; a horizontal fixing rod 12 fixedly connected between the two end walls of the strip-shaped groove 11 by welding, providing support and guidance for subsequent components; a second spring 13 sleeved around the horizontal fixing rod 12, the spring 13 having a certain length in its natural state; a movable sleeve block 14 slidably sleeved around the horizontal fixing rod 12, allowing it to slide freely along the horizontal fixing rod 12; and a fixing block 15 fixedly connected to the surface of the movable sleeve block 14 by welding, serving to connect and transmit force. At one end of the fixing block 15, a limiting rod 16 is fixedly connected by welding, and the position of the limiting rod 16 corresponds to the limiting hole 10. When the L-shaped protective plate 5 is inserted into the appropriate position, under the action of the second spring 13, the moving sleeve 14 drives the fixing block 15 and the limiting rod 16 to move, so that the limiting rod 16 is inserted into the limiting hole 10, thereby achieving the limiting and fixing of the L-shaped protective plate 5.

[0030] Furthermore, a strip-shaped groove 6 is cut into the inner wall of the rectangular through groove 4 using a cutting process. The size of the strip-shaped groove 6 is designed according to the installation requirements of each component of the reset structure. A fixing rod 7 is fixedly connected between the two end walls of the strip-shaped groove 6 by welding. The fixing rod 7 provides support and guidance for subsequent components. A spring 8 is sleeved around the fixing rod 7, and the spring 8 has a certain length in its natural state. A sliding sleeve block 9 is slidably sleeved around the fixing rod 7. The sliding sleeve block 9 can slide freely on the fixing rod 7 and is slidably connected to the inner wall of the strip-shaped groove 6 to ensure stable sliding direction. The opposing surfaces of the two sliding sleeve blocks 9 are fixedly connected to the two end surfaces of an L-shaped protective plate 5 by welding. When the L-shaped protective plate 5 is moved within the rectangular through groove 4 under external force, it will cause the sliding sleeve block 9 to slide on the fixing rod 7, simultaneously compressing the spring 8. When the external force disappears, under the elastic force of the spring 8, the sliding sleeve block 9 will cause the L-shaped protective plate 5 to automatically reset.

[0031] Furthermore, the movable sleeve 14, through its sliding engagement with the horizontal fixing rod 12, can slide freely within the inner wall of the strip groove 11. A sliding groove 17 is cut into the surface of the fixed block 15 using a cutting process. The shape and size of the sliding groove 17 are designed to facilitate the application of external force by the operator using their fingers or other tools. When it is necessary to move the L-shaped protective plate 5, the operator can insert their fingers into the sliding groove 17 and apply external force to one side, causing the fixed block 15 to slide the movable sleeve 14 within the strip groove 11. This, in turn, causes the limiting rod 16 to disengage from the limiting insertion hole 10, allowing the L-shaped protective plate 5 to move freely.

[0032] Furthermore, one end of the limiting rod 16 is accurately inserted into the inner wall of the limiting hole 10. During the design and manufacturing process, the inner diameter of the limiting hole 10 and the outer diameter of the limiting rod 16 are strictly controlled to ensure they are compatible. Specifically, the inner diameter of the limiting hole 10 is slightly larger than the outer diameter of the limiting rod 16, ensuring that the limiting rod 16 can be smoothly inserted into the limiting hole 10 and remains relatively stable after insertion, without any shaking or loosening. Once the limiting rod 16 is inserted into the limiting hole 10, the L-shaped protective plate 5 is firmly fixed to the bearing plate 1 and cannot move freely, effectively preventing materials from slipping off the side during transportation.

[0033] Furthermore, one end of spring 13 is fixedly connected to the end wall of the strip groove 11 by welding, and the other end of spring 13 is fixedly connected to one end surface of the movable sleeve block 14 by welding. When the operator applies external force through the sliding groove 17 to move the fixed block 15 and the movable sleeve block 14, spring 13 will be compressed. When the external force disappears, under the elastic force of spring 13, the movable sleeve block 14 will drive the fixed block 15 and the limiting rod 16 to move in opposite directions, so that the limiting rod 16 is re-inserted into the limiting hole 10, thereby achieving the re-limiting and fixing of the L-shaped protective plate 5.

[0034] Furthermore, one end of spring 8 is fixedly connected to the end wall of the strip groove 6 by welding, and the other end of spring 8 is fixedly connected to one end surface of the sliding sleeve block 9 by welding. When the L-shaped protective plate 5 moves within the rectangular through groove 4 under the action of external force, it will cause the sliding sleeve block 9 to slide on the fixed rod 7, while compressing spring 8. When the external force disappears, under the elastic force of spring 8, the sliding sleeve block 9 will cause the L-shaped protective plate 5 to automatically return to its initial position along the fixed rod 7, ensuring that the L-shaped protective plate can always effectively prevent materials from falling to the side.
