Description

Technical Field

[0001] This utility model relates to the field of material transport trolley technology, specifically to a material transport trolley for building bridge construction. Background Technology

[0002] Bridge construction refers to the process of building a bridge according to its design specifications. It mainly includes bridge construction technology, construction organization, construction management, and construction quality. Material transport carts are used to transport construction materials during the bridge construction process.

[0003] Existing material transport trolleys for bridge construction typically transport building materials by placing them in the truck bed and then pushing the trolley. However, this method is limited by the limited space in the truck bed, restricting its use to transport only small building materials. Since building materials are diverse, such as steel bars of a certain length essential for bridge construction, the lack of a suitable load-bearing mechanism can cause the bars to slip during transport, resulting in poor transport efficiency and limited applicability. Therefore, there is an urgent need for a new material transport trolley for bridge construction to address these issues. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] The technical problem to be solved by this utility model is to provide a material transport trolley for construction bridges that can simultaneously transport small building materials and steel bars, with good transport effect and high applicability, in light of the current state of the technology.

[0006] (II) Technical Solution

[0007] This utility model is achieved through the following technical solution: This utility model proposes a material transport trolley for building bridge construction, including a vehicle body. Two sets of supports are symmetrically installed on the two side walls of the vehicle body. A bidirectional screw is arranged between the supports. A handwheel is connected to one end of the bidirectional screw. A guide rod is installed on one side of the bidirectional screw. Two sets of screw blocks are symmetrically sleeved on the bidirectional screw and the guide rod. A linkage rod is installed on the screw blocks. A U-shaped bearing seat is provided at one end of the linkage rod. A rotating shaft is installed inside the bearing seat. Multiple sets of arc-shaped limiting grooves are arrayed on the upper end of the bearing seat.

[0008] Furthermore, the support is welded to the vehicle body, the bidirectional screw is rotatably installed between the supports, and the handwheel is fixed to one end of the bidirectional screw.

[0009] By adopting the above technical solution, the handwheel can drive the bidirectional screw to rotate.

[0010] Furthermore, the guide rod is welded between the supports, the screw block is threadedly connected to the bidirectional screw, and the guide rod passes through the screw block.

[0011] By adopting the above technical solution, during the rotation of the bidirectional screw, the screw block moves under the action of the thread and the guide rod.

[0012] Furthermore, one end of the linkage rod is hinged to the screw block, and the other end of the linkage rod is sleeved on the rotating shaft.

[0013] By adopting the above technical solution, during the movement of the screw block, the linkage rod rotates and drives the bearing seat to move, thereby adjusting the distance between the two sets of bearing seats according to the length of the reinforcing bar.

[0014] Furthermore, the rotating shaft is rotatably mounted between the bearing seats, and the limiting groove is formed on the bearing seat.

[0015] By adopting the above technical solution, the limiting groove can provide a placement position for the reinforcing bars and limit their movement, ensuring the stability of the reinforcing bars during transportation.

[0016] Furthermore, two sets of movable wheels are rotatably installed on both sides of the bottom of the vehicle body, two sets of support legs are symmetrically welded to one side of the bottom of the vehicle body, and two sets of push handles are symmetrically welded to one side wall of the vehicle body.

[0017] By adopting the above technical solution, the movable wheels facilitate the movement of the vehicle body to transport materials, and the support legs can provide auxiliary support to the vehicle body when it is stopped.

[0018] Furthermore, a baffle is slidably inserted into the end of the vehicle body away from the push handle, and a pull handle is fixed to the top of the baffle.

[0019] By adopting the above technical solution, the baffle can seal one end of the vehicle body, thereby limiting the material inside the vehicle body. Separating the baffle from the vehicle body facilitates unloading.

[0020] (III) Beneficial Effects

[0021] Compared with the prior art, this utility model has the following advantages:

[0022] To address the problem that existing construction material transport trolleys for bridge and building projects typically transport building materials by placing them in the trolley's cargo bed and then pushing the trolley, this method suffers from limitations. The limited space in the cargo bed restricts the transport of only small building materials. However, various building materials exist, and for example, steel bars of a certain length are essential for bridge construction. The lack of a proper support mechanism for these materials leads to the bars slipping, resulting in poor transport efficiency and limited applicability. This invention addresses this issue by incorporating a bidirectional screw, guide rod, screw block, linkage rod, support seat, and limiting groove. During operation, the trolley carries small building materials, and a handwheel drives the bidirectional screw, causing the screw block to move under the influence of the screw thread and guide rod. Simultaneously, the linkage rod rotates, moving the support seat. The spacing between the two sets of support seats is adjusted according to the length of the steel bar, and the limiting groove further restricts the load on the steel bar. This allows for the simultaneous transport of small building materials and steel bars, effectively improving the device's transport efficiency and applicability. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] like Figures 1-3As shown in this embodiment, a material transport trolley for bridge construction includes a vehicle body 1. Two sets of supports 12 are symmetrically installed on the two side walls of the vehicle body 1. A bidirectional screw 7 is arranged between the supports 12. One end of the bidirectional screw 7 is connected to a handwheel 11, which can drive the bidirectional screw 7 to rotate. A guide rod 9 is installed on one side of the bidirectional screw 7. Two sets of screw blocks 14 are symmetrically sleeved on the bidirectional screw 7 and the guide rod 9. During the rotation of the bidirectional screw 7, the screw blocks 14 move under the action of the screw thread and the guide rod 9. A linkage rod 8 is installed on the screw block 14. A U-shaped bearing seat 5 is provided at one end of the linkage rod 8. A rotating shaft 13 is installed in the bearing seat 5. During the movement of the screw block 14, the linkage rod 8 rotates accordingly and drives the bearing seat 5 to move. The distance between the two sets of bearing seats 5 is adjusted according to the length of the reinforcing bar. Multiple sets of arc-shaped limiting grooves 6 are arrayed on the upper end of the bearing seat 5. The limiting grooves 6 can provide a placement position for the reinforcing bar and limit its movement to ensure the stability of the reinforcing bar during transportation.

[0030] like Figures 1-3 As shown, in this embodiment, the support 12 is welded to the vehicle body 1, the bidirectional screw 7 is rotatably installed between the supports 12, the handwheel 11 is fixed to one end of the bidirectional screw 7, the guide rod 9 is welded between the supports 12, the screw block 14 is connected to the bidirectional screw 7 by a thread, the guide rod 9 passes through the screw block 14, one end of the linkage rod 8 is hinged to the screw block 14, and the other end of the linkage rod 8 is sleeved on the rotating shaft 13. The rotating shaft 13 is rotatably installed between the bearing seats 5, and the limiting groove 6 is formed on the bearing seat 5.

[0031] like Figures 1-3 As shown in this embodiment, two sets of movable wheels 4 are rotatably installed on both sides of the bottom end of the vehicle body 1. Two sets of support legs 3 are symmetrically welded to one side of the bottom end of the vehicle body 1. Two sets of push handles 2 are symmetrically welded to one side wall of the vehicle body 1. The movable wheels 4 facilitate the movement of the vehicle body 1 to transport materials. The support legs 3 can provide auxiliary support when the vehicle body 1 stops.
