Description

Technical Field

[0001] This utility model relates to the field of building material handling technology, and in particular to a handling device for road and bridge construction materials. Background Technology

[0002] As the scale of construction continues to expand, the requirements for construction progress are increasing. Large-scale road and bridge projects often need to transport a huge amount of building materials in a short period of time. Traditional transportation methods simply cannot meet this demand. At the same time, the types of road and bridge building materials are becoming more and more complex, and new materials are constantly emerging. These materials differ significantly in shape, size, weight and material properties, which brings greater challenges to the transportation work. For example, some bridge components made of new composite materials require both avoiding collision damage during transportation and precise positioning and installation.

[0003] Existing technologies, such as the utility model patent with publication number CN218505902U, disclose a green building material transportation device. This patent uses a transportation base plate, with a rear barrier plate fixedly connected to one side of the base plate. A rotating column is rotatably connected inside the rear barrier plate, and a guide plate is rotatably connected to one side of the base plate. A traction rope is fixedly connected between the guide plate and the rotating column, and a limit rope is fixedly connected to one side of the rotating column. By rotating the rotating column, the guide plate is tilted to a suitable angle, allowing the boards at the top of the base plate to be placed at an angle and pass through a narrower channel. This allows workers to independently transport excessively long boards, avoiding the need for workers to call for help and improving construction efficiency. The expansion of the front and side plates allows workers to transport more and larger building materials, and the expansion of the front plate continuously tightens and secures the building materials to prevent them from falling off. This solves the problems of boards slipping due to excessive weight during handling, causing injuries, and the inability of construction workers to handle the materials independently, thus reducing construction efficiency.

[0004] Existing handling devices, such as those described above, often encounter problems when transporting building materials. Construction sites are typically uneven with frequent potholes and slopes. When carrying heavy loads on the base plate, the wheels are prone to slipping due to ground conditions or slight external forces. On sloping construction sections, if the wheels are not locked, they may slip instantly when the vehicle stops, causing the entire vehicle to tip over. This could not only damage valuable building materials but also cause serious injury or death to nearby construction workers, posing a significant threat to the installation order at the construction site. Utility Model Content

[0005] The purpose of this utility model is to solve the problem in the existing technology that, due to the common unevenness and undulating slopes at construction sites, when heavy objects on the base plate need to be moved, the wheels are prone to slipping due to ground conditions or slight external forces. On construction sections with shifting slopes, if the wheels are not locked, they may slip instantly once the transport vehicle stops, causing the entire vehicle to tip over. This not only damages valuable building materials but may also cause serious injury or death to nearby construction workers, greatly threatening the installation order at the construction site. Therefore, this utility model proposes a transport device for road and bridge construction materials.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a handling device for road and bridge construction materials, comprising a base plate, wheels, and anti-slip components. The wheels are fixedly installed on the lower surface of the base plate, the anti-slip components are fixedly installed on the side surface of the base plate, a limit component is fixedly installed on the side surface of the base plate, a front blocking plate is fixedly installed on the upper surface of the base plate, a push handle is fixedly installed on the side of the front blocking plate away from the base plate, an extension side plate is movably arranged on the upper surface of the base plate, the extension side plate is engaged with the front blocking plate, a rear plate unfolding mechanism is movably arranged on the side of the base plate away from the front blocking plate, the rear plate unfolding mechanism includes an installation groove, the installation groove is opened on the side of the base plate away from the front blocking plate, the number of installation grooves is two, and the two installation grooves are symmetrically arranged at the center of the base plate.

[0007] Preferably, a linkage spring is fixedly connected to the inner wall of the mounting groove, a guide plate is fixedly connected to the side of the linkage spring away from the bottom plate, and a rear blocking plate is fixedly connected to the side of the guide plate away from the linkage spring. The rear blocking plate is rectangular and contacts the side surface of the extension side plate. Through the cooperation of the linkage spring and the guide plate, the position of the rear blocking plate can be easily adjusted to ensure that the transport vehicle can transport longer building materials.

[0008] Preferably, the anti-slip component includes a mounting plate, which is fixedly mounted on the side surface of the base plate. The mounting plate is rectangular in shape, and a return spring is fixedly connected to the lower surface of the mounting plate. There are two return springs, which are symmetrically arranged at the center of the mounting plate. The return springs facilitate the application of a return force to the pedal to ensure that the abutment can rebound upward and thus release the restriction on the wheel position.

[0009] Preferably, a stop plate is fixedly connected to the side of the return spring away from the mounting plate. The stop plate is arranged in an "L" shape and is slidably connected to the side surface of the mounting plate. There are two stop plates, which are symmetrically arranged at the center of the base plate. A shaft is fixedly connected to the upper surface of the stop plate and passes through the mounting plate. A foot pedal is fixedly connected to the side of the shaft away from the stop plate and is fixedly connected to the side surface of the stop plate. By stepping on the foot pedal, it is convenient for the operator to directly restrict the position of the wheel.

[0010] Preferably, an anti-slip pad layer is fixedly connected to the lower surface of the support plate. The anti-slip pad layer abuts against the ground, and the lower surface of the anti-slip pad layer is corrugated. The anti-slip pad layer helps to increase the friction between the support plate and the ground, thereby ensuring the stability of the support plate when it is supported.

[0011] Preferably, the limiting component includes a mounting box, which is fixedly connected to the side surface of the base plate. A guide groove is provided on the side of the mounting box near the mounting plate, and a limiting spring is fixedly connected to the side of the mounting box away from the guide groove. The limiting spring is disposed inside the mounting box, and a linkage block is fixedly connected to the side of the limiting spring away from the mounting box. The guide groove facilitates the guidance of the direction of movement of the limiting plate, thereby ensuring that the limiting plate moves in a horizontal direction.

[0012] Preferably, a long rod is fixedly connected to the side of the linkage block near the limiting spring. The long rod passes through the mounting box. A pull block is fixedly connected to the side of the long rod away from the guide groove. The pull block contacts the side surface of the mounting box. The limiting spring facilitates the application of a reset spring force to the linkage block.

[0013] Preferably, a limiting plate is fixedly connected to the lower surface of the linkage block. The limiting plate is in contact with the inner wall of the mounting box, and is slidably connected to the inner wall of the guide groove. The limiting plate abuts against the outer surface of the abutment and the outer surface of the pedal. The limiting plate facilitates the restriction of the position of the abutment to ensure the stability of the abutment during support.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] In this invention, by setting an anti-slip component, when the position of the transport vehicle needs to be fixed, the worker can step on the foot pedal and then press down on the foot pedal. The foot pedal moves the stop plate downward, which stretches the return spring. The return spring deforms due to stretching, and the downward movement of the stop plate causes the position of the limiting plate to be unrestricted. Then the limiting plate loses pressure on the linkage block, and the linkage block loses pressure on the limiting spring. The limiting spring is released from pressure and returns to its original position, which then moves the limiting plate in the direction guided by the guide groove. When the moving plate comes into contact with the upper surface of the stop plate, the position of the stop plate is restricted. The worker can then remove their foot, allowing the anti-slip pad to directly contact the ground and preventing the wheels from moving while stationary.

[0016] Furthermore, when it is necessary to lock the wheels, the worker only needs to hold the pull block with one hand and pull it outward. The pull block, under force, moves the long rod, compressing the limit spring. The limit spring deforms under compression, and then the linkage block moves, causing the limit plate to move into the mounting box along the direction guided by the guide groove. This movement removes the restriction on the abutment plate and pedal, and the return spring loses its tension, causing the abutment plate to rebound. Then the position of the transport vehicle can be moved again. By setting anti-slip components, the wheels can be prevented from shaking and shifting during transport, avoiding the transport vehicle from tipping over due to unstable support. This ensures the safety of building materials and equipment during transportation and provides a solid guarantee for the smooth progress of construction. Attached Figure Description

[0025] Please see Figures 1-6 This utility model provides a technical solution: a handling device for road and bridge construction materials, including a base plate 1, wheels 2 and anti-slip components 3. The wheels 2 are fixedly installed on the lower surface of the base plate 1, the anti-slip components 3 are fixedly installed on the side surface of the base plate 1, the side surface of the base plate 1 is fixedly provided with a limit component 4, the upper surface of the base plate 1 is fixedly installed with a front blocking plate 5, the side of the front blocking plate 5 away from the base plate 1 is fixedly installed with a push handle 6, the upper surface of the base plate 1 is movably provided with an extension side plate 7, the extension side plate 7 is engaged with the front blocking plate 5, and the side of the base plate 1 away from the front blocking plate 5 is movably provided with a rear plate unfolding mechanism 8.

[0026] The following section will explain the specific settings and functions of its anti-slip component 3 and limiting component 4.

[0027] In this embodiment: the rear plate unfolding mechanism 8 includes a mounting groove 81. The bottom plate 1 is provided with a mounting groove 81 on the side away from the front blocking plate 5. There are two mounting grooves 81, and the two mounting grooves 81 are located at the center of the bottom plate 1 and are arranged symmetrically on the left and right.

[0028] Specifically, a linkage spring 82 is fixedly connected to the inner wall of the mounting groove 81. A guide plate 83 is fixedly connected to the side of the linkage spring 82 away from the base plate 1. A rear blocking plate 84 is fixedly connected to the side of the guide plate 83 away from the linkage spring 82. The rear blocking plate 84 is rectangular and contacts the side surface of the extension side plate 7.

[0029] The effect achieved by the above components is that, through the cooperation of the linkage spring 82 and the guide plate 83, the position of the rear stop plate 84 can be easily adjusted to ensure that the transport vehicle can transport longer building materials.

[0030] Specifically, the anti-slip component 3 includes a mounting plate 31, which is fixedly mounted on the side surface of the base plate 1. The mounting plate 31 is rectangular in shape, and a return spring 32 is fixedly connected to the lower surface of the mounting plate 31. There are two return springs 32, which are located at the center of the mounting plate 31 and are arranged symmetrically from left to right.

[0031] The effect achieved by the above components is that the return spring 32 facilitates the application of a return force to the pedal 35, so as to ensure that the abutment 33 can rebound upward and then release the restriction on the position of the wheel 2.

[0032] Specifically, a stop plate 33 is fixedly connected to the side of the return spring 32 away from the mounting plate 31. The stop plate 33 is L-shaped and is slidably connected to the side surface of the mounting plate 31. There are two stop plates 33, which are symmetrically arranged at the center of the base plate 1. A shaft 34 is fixedly connected to the upper surface of the stop plate 33. The shaft 34 passes through the mounting plate 31. A foot pedal 35 is fixedly connected to the side of the shaft 34 away from the stop plate 33. The foot pedal 35 is fixedly connected to the side surface of the stop plate 33.

[0033] The effect achieved by the above components is that by stepping on the pedal 35, the operator can easily and directly restrict the position of the wheel 2.

[0034] Specifically, an anti-slip pad 36 is fixedly connected to the lower surface of the abutment 33. The anti-slip pad 36 abuts against the ground, and the lower surface of the anti-slip pad 36 is corrugated.

[0035] The effect achieved by the above components is that the anti-slip pad 36 facilitates the increase of friction between the support plate 33 and the ground, thereby ensuring the stability of the support plate 33 during support.

[0036] Specifically, the limiting component 4 includes a mounting box 41, which is fixedly connected to the side surface of the base plate 1. A guide groove 42 is provided on the side of the mounting box 41 near the mounting plate 31. A limiting spring 43 is fixedly connected on the side of the mounting box 41 away from the guide groove 42. The limiting spring 43 is located inside the mounting box 41. A linkage block 44 is fixedly connected on the side of the limiting spring 43 away from the mounting box 41.

[0037] The effect achieved by the above components is that the guide groove 42 facilitates the direction of movement of the limiting plate 47, thereby ensuring that the limiting plate 47 moves in a horizontal direction.

[0038] Specifically, a long rod 45 is fixedly connected to the side of the linkage block 44 near the limit spring 43. The long rod 45 passes through the mounting box 41. A pull block 46 is fixedly connected to the side of the long rod 45 away from the guide groove 42. The pull block 46 is in contact with the side surface of the mounting box 41.

[0039] The effect achieved by the above components is that the limiting spring 43 facilitates the application of a reset spring force to the linkage block 44.

[0040] Specifically, the lower surface of the linkage block 44 is fixedly connected to the limiting plate 47, the limiting plate 47 is in contact with the inner wall of the mounting box 41, the limiting plate 47 is slidably connected to the inner wall of the guide groove 42, the limiting plate 47 is in contact with the outer surface of the abutment plate 33, and the limiting plate 47 is in contact with the outer surface of the pedal 35.

[0041] The effect achieved by the above components is that the position of the abutment plate 33 is easily restricted by the limiting plate 47, so as to ensure the stability of the abutment plate 33 when it is supported.

[0042] Working principle: When the position of the transport vehicle needs to be fixed, the operator can step on the foot pedal 35 and press down on the foot pedal 35. The foot pedal 35 moves the abutment plate 33 downward, which stretches the return spring 32. The return spring 32 is stretched and deformed, and the abutment plate 33 moves downward, so that the position of the limiting plate 47 is no longer restricted. Then the limiting plate 47 loses pressure on the linkage block 44, and the linkage block 44 loses pressure on the limiting spring 43. The limiting spring 43 is released from pressure and returns to its original position, which then moves the limiting plate 47 in the direction guided by the guide groove 42. When the moving plate 47 comes into contact with the upper surface of the abutment plate 33, the position of the abutment plate 33 is restricted. Then the operator can remove their foot, so that the anti-slip pad 36 is in direct contact with the ground, preventing the wheels 2 from moving when they are stationary.

[0043] Furthermore, when it is necessary to unlock wheel 2, the worker only needs to hold the pull block 46 with one hand and pull it outward. The pull block 46, under force, drives the long rod 45 to move, which compresses the limit spring 43. The limit spring 43 deforms under compression, and then the linkage block 44 moves, driving the limit plate 47 to move into the mounting box 41 along the direction guided by the guide groove 42. The movement removes the restriction on the abutment plate 33 and the foot pedal 35, and the reset spring 32 loses its tension, causing the abutment plate 33 to rebound. Then the position of the transport vehicle can be moved again. By setting the anti-slip component 3, the wheel 2 can be prevented from shaking and shifting during transportation, avoiding the transport vehicle from tipping over due to unstable support, ensuring the safety of building materials and equipment during transportation, and providing a solid guarantee for the smooth progress of construction.
