[0002] Construction engineering is a process of creating and completing buildings through a series of steps such as design, planning, construction, and management. It covers all aspects from the initial conceptual design to the final completion, including land preparation, foundation construction, structure erection, decoration, and equipment installation. In construction engineering, transport vehicles play a crucial role, providing necessary support and convenience for site transportation. Since construction projects usually require a large amount of materials and equipment, these materials are usually stored in warehouses and retrieved when needed.

[0003] Therefore, the utility model patent with the publication number CN208036317U discloses a transport vehicle for construction engineering, including a bottom plate and a lifting connecting steel plate, and the lifting connecting steel plate is welded to the bottom plate. A number of connecting blocks are provided at the bottom of the bottom plate, and the connecting blocks are welded to the bottom plate. This kind of transport vehicle for construction engineering adopts four-wheel drive to solve the problem that the previous single-wheel operation is prone to rollover, and a ground shock absorber is also provided on the transport vehicle to play a shock-absorbing role during the operation of the transport vehicle, greatly improving the transportation stability during the process of transporting materials, effectively preventing the phenomenon that the construction engineering materials fall due to the vibration of the transport vehicle, and at the same time greatly improving the safety of the construction engineering materials and the staff. The rectangular groove provided on the transport vehicle can play a role in providing a place for the staff to place water cups, and the setting of the lifting connecting steel plate provides a more comfortable and convenient way to push the cart for staff at different heights, making their work efficiency higher.

[0004] However, this patent cannot effectively restrict the materials in the transport box. When encountering bumpy roads during transportation, the objects in the transport box are prone to collide with each other, easily damaging the materials. Moreover, the transport box of this patent is relatively fixed, and it is necessary to take out all the materials in the transport box to carry out a new round of transportation, which is rather troublesome. Content of the Utility Model

[0005] The purpose of the utility model is to provide a transport vehicle for construction engineering aiming at the above-mentioned deficiencies of the prior art. It can effectively restrict the movement of materials, avoid mutual collision, and can quickly unload materials, facilitating a new round of transportation.

[0006] The technical solution adopted by the utility model is a transport vehicle for construction projects, including a bottom plate. Support legs integrally formed with the bottom plate are provided at the four corners of the bottom plate. Universal wheels are fixedly installed at the tops of the support legs. A pair of push columns are fixedly installed at one end of the bottom plate. The pair of push columns are symmetrically arranged. A push rod is arranged inside the pair of push columns, and both ends of the push rod are fixedly connected to the pair of push columns respectively. A connecting device is provided at the top of the bottom plate. A transport box is fixedly connected to the top of the bottom plate through the connecting device. A box cover is in contact with the top of the transport box. Self-locking devices are provided on both sides of the box cover. A fixing device for effectively restricting the movement of materials is provided in the middle of the box cover.

[0007] Preferably, the connecting device includes a chute and an installation groove. The chute is opened at the top of the bottom plate. A slider is slidably installed in the chute. The top of the slider is fixedly connected to the transport box. The installation groove is opened near the opening of the chute. A first spring is provided in the installation groove. One end of the first spring is fixedly connected to the bottom of the installation groove, and the other end is fixedly connected to a clamping block.

[0008] Preferably, the self-locking device includes a connecting column and a fixing block. The top of the connecting column is fixedly connected to the bottom of the box cover. A receiving groove is opened at the bottom end of the connecting column. A second spring is provided in the receiving groove. One end of the second spring is fixedly connected to the bottom of the receiving groove, and the other end is fixedly connected to a telescopic column. The fixing block is fixedly installed on the outer wall of the transport box. A through hole is opened in the middle of the fixing block. The telescopic column is arranged in the through hole through the second spring.

[0009] Preferably, the fixing device includes a support plate. Support columns integrally formed with the support plate are provided at the four corners of the bottom of the support plate. The bottoms of the support columns are fixedly connected to the top of the box cover. Threaded holes are opened in the middle of both the box cover and the support plate. A threaded rod is threadedly connected in the threaded hole. The bottom of the threaded rod is rotatably connected to a protection block. A handle is fixedly connected to the top of the threaded rod.

[0010] Preferably, rounded corners are opened at the sharp corners of the bottom plate.

[0011] Preferably, a towing block is provided inside one end of the bottom plate away from the push rod.

[0012] Preferably, an anti-slip sleeve is sleeved on the surface of the handle.

[0013] The utility model is simple and convenient to use. Just hold the push columns to push the universal wheels to move, and then drive the transport box to move. After putting the materials to be transported into the transport box and covering the box cover, the self-locking device will fix the box cover. Then hold the handle and rotate it to make the threaded rod rotate in the threaded hole, and then drive the protection block to wrap the materials in the transport box, so as to limit the movement range of the materials and avoid the materials from knocking against each other. When discharging the materials, the clamping block can also be pressed. At this time, the transport box can be removed from the bottom plate, and then the user can take the bottom plate back, which is convenient for transportation again.

[0014] Compared with the prior art, the beneficial effect of the present utility model is that it can effectively limit the movement range of the materials in the transport box, thereby avoiding mutual collision between the materials in the transport box. The transport box can also be disassembled, which is convenient for the bottom plate to quickly enter a new round of transportation, effectively improving the transportation efficiency.

DETAILED DESCRIPTION OF THE INVENTION

[0021] Figure 1Schematically shows a transport vehicle for construction engineering of the present utility model, including a bottom plate 1. At the four corners of the bottom plate 1, there are support legs 12 integrally formed with the bottom plate 1. At the tops of the support legs 12, universal wheels 13 are fixedly installed. At one end of the bottom plate 1, a pair of push columns 14 are fixedly installed. The pair of push columns 14 are symmetrically arranged. Inside the pair of push columns 14, there is a push rod 15. The two ends of the push rod 15 are respectively fixedly connected to the pair of push columns 14. On the top of the bottom plate 1, there is a connecting device 2. The top of the bottom plate 1 is fixedly connected to a transport box 16 through the connecting device 2. On the top of the transport box 16, there is a box cover 17 in contact. On both sides of the box cover 17, there are self-locking devices 3. In the middle of the box cover 17, there is a fixing device 4 that can effectively limit the movement of materials. At the sharp corners of the bottom plate 1, round corners 5 are provided. The round corners 5 can effectively reduce the damage caused by bumps and can also prevent scratching the user. Inside one end of the bottom plate 1 away from the push rod 15, there is a towing block 6. The towing block 6 facilitates the user to connect the device to a transport vehicle through tools such as ropes, which can further expand the transport range of the device.

[0022] As Figure 2 shown, the connecting device 2 includes a sliding groove 21 and an installation groove 23. The sliding groove 21 is opened on the top of the bottom plate 1. Inside the sliding groove 21, a sliding block 22 is slidably installed. The top of the sliding block 22 is fixedly connected to the transport box 16. The installation groove 23 is opened near the opening of the sliding groove 21. Inside the installation groove 23, there is a first spring 24. One end of the first spring 24 is fixedly connected to the bottom of the installation groove 23, and the other end is fixedly connected to a clamping block 25.

[0023] In a specific implementation, only need to press the clamping block 25 to make the clamping block 25 compress the first spring 24 and retract into the installation groove 23. At this time, the transport box 16 can be pushed, and then the sliding block 22 is driven to slide out of the sliding groove 21, so as to remove the transport box 16. And to install the transport box 16, only need to align the sliding block 22 with the sliding groove 21 and then press the clamping block 25. At this time, the transport box 16 can be slid into the bottom plate 1 through the sliding block 22. At this time, the compressed first spring 24 will reset, and then push the clamping block 25 to extend, so as to limit the sliding range of the transport box 16, thus completing the fixation.

[0024] As Figure 2 、 Figure 3 and Figure 4The self-locking device 3 shown includes a connecting column 31 and a fixing block 35. The top of the connecting column 31 is fixedly connected to the bottom of the box cover 17. A receiving groove 32 is formed in the bottom end of the connecting column 31. A second spring 33 is arranged in the receiving groove 32. One end of the second spring 33 is fixedly connected to the bottom of the receiving groove 32, and the other end is fixedly connected to a telescopic column 34. The fixing block 35 is fixedly installed on the outer wall of the transport box 16. A through hole 36 is formed in the middle of the fixing block 35. The telescopic column 34 is arranged in the through hole 36 through the second spring 33. The fixing device 4 includes a support plate 41. Support columns 42 integrally formed with the support plate 41 are arranged at the four corners of the bottom of the support plate 41. The bottom of the support column 42 is fixedly connected to the top of the box cover 17. Threaded holes 43 are formed in the middle of both the box cover 17 and the support plate 41. A threaded rod 44 is threadedly connected in the threaded hole 43. The bottom of the threaded rod 44 is rotatably connected to a protection block 45. The protection block 45 can be made of a flexible material such as rubber or sponge, and can effectively wrap the materials in the transport box 16. The top of the threaded rod 44 is fixedly connected to a handle 46. An anti-slip sleeve is sleeved on the surface of the handle 46. The anti-slip sleeve can be made of a flexible material such as rubber, which can effectively prevent slipping due to sweat on the hand and can also improve the comfort when holding.

[0025] In a specific implementation, just align the protection block 45 with the transport box 16, then cover the box cover 17, and press the telescopic column 34 to compress the second spring 33 and retract it into the receiving groove 32. At this time, align the telescopic column 34 with the through hole 36 and then release the hand. The compressed second spring 33 will push the telescopic column 34 through the through hole 36, thereby restricting the vertical up-and-down movement range of the box cover 17, and the left-and-right and front-and-back movement ranges of the box cover 17 will also be restricted by the protection block 45. At this time, hold the handle 46 and rotate it. The rotation of the handle 46 will drive the threaded rod 44 to rotate in the threaded hole 43, thereby causing the threaded rod 44 to move downward. The downward movement of the threaded rod 44 will drive the protection block 45 to move downward, thereby causing the protection block 45 to compress the free space in the transport box 16, thereby restricting the movement range of the materials in the transport box 16 and avoiding their mutual collision.
