Description

Technical Field

[0001] The utility model belongs to the technical field of building block packaging and transportation, in particular to a building block packaging and transportation trolley. Background Art

[0002] Blocks are an excellent new type of building material. Compared with traditional concrete blocks, aerated concrete blocks have the advantages of being lightweight and porous, heat-insulating, fire-resistant, and environmentally friendly. They can be processed into the required shape using nails, saws, planers, etc. They also have a certain earthquake resistance and are widely used in high-rise frame structures. When aerated concrete blocks are just produced, the temperature is still very high and they need to be cooled outdoors before they can be packaged and transported. When transporting aerated concrete blocks to the packaging area, a transport trolley is required.

[0003] Because aerated concrete blocks are mostly directly stacked together when they are cooled, it is necessary to manually or use equipment to move the aerated concrete blocks from the ground to the rear of the transport vehicle when transporting the aerated concrete blocks to the transport vehicle. However, after being transported to the transport vehicle, they still need to be manually pushed to the inside of the vehicle body and then placed and stacked. This process is not only time-consuming and labor-intensive, but also easily causes collisions between the aerated concrete blocks, resulting in damage to the aerated concrete blocks and affecting the quality. Therefore, a block packaging and transportation trolley is proposed to address the above problems. Utility Model Content

[0004] In order to solve the problems raised in the above background technology, the utility model provides a trolley for packaging and transporting building blocks, which can solve the problem that it is troublesome and easy to bump into the building blocks when placing them on the trolley manually.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a trolley for packaging and transporting building blocks, comprising a body, a reduction motor fixedly connected to one end of the body, a lead screw rotatably connected to the body, a pair of support rods fixedly connected to the body, a pushing block mounted on the lead screw and the support rods, a sliding push-pull block movably connected to the body, a hydraulic telescopic rod fixedly connected to the body in a mirror-image manner, an extrusion limit block fixedly connected to the top of the hydraulic telescopic rod, a limited slide rail slidably connected to the body, and a pull rod is provided at one end of the body.

[0006] Preferably, a baffle is provided on the top of the vehicle body, a slide groove is provided in the middle of the vehicle body and the sliding push-pull block slides inside the slide groove.

[0007] Preferably, the reduction motor is used to drive the lead screw to rotate, so that the lead screw drives the push block to slide on the support rod.

[0008] Preferably, the lead screw and the support rod are located inside the sliding push-pull block, and the lead screw and the support rod are distributed in a triangle.

[0009] Preferably, the pushing block is located inside the sliding push-pull block and is slidably connected to the sliding push-pull block, and a friction layer is provided on the top of the sliding push-pull block.

[0010] Preferably, the sliding push-pull block is located inside the limiting slide rail and is slidably connected to the limiting slide rail, the extrusion limiting block is located at the bottom of the limiting slide rail, and an inclined surface is provided on the upper end of the extrusion limiting block.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] The utility model can effectively solve the problem that it is troublesome and easy to bump into the building blocks when placing them on the vehicle manually through the cooperation of the lead screw, the pushing block, the sliding push-pull block and the extrusion limit block. The extrusion limit block pushes the limit slide rail to drive the sliding push-pull block to move upward, so that the friction layer on the top of the sliding push-pull block extends out of the top surface of the vehicle body. The push block is driven to slide by the rotation of the lead screw, and then the sliding push-pull block drives the building blocks to move inside the vehicle body, which is convenient for loading and saves manpower.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figures 1 to 5 As shown, the utility model provides a trolley for packaging and transporting building blocks, including a body 1, a reduction motor 2 is fixedly connected to one end of the body 1, a lead screw 3 is rotatably connected to the body 1, a pair of support rods 4 are fixedly connected to the body 1, a pushing block 5 is sleeved on the lead screw 3 and the support rod 4, a sliding push-pull block 6 is movably connected to the body 1, a hydraulic telescopic rod 7 is fixedly connected to the body 1 in a mirror-like manner, an extrusion limit block 8 is fixedly connected to the top of the hydraulic telescopic rod 7, a limit slide rail 9 is slidably connected to the body 1, and a pull rod 10 is arranged at one end of the body 1.

[0021] After the vehicle body 1 is lifted up, the push block 5 is pushed back to the left by the hydraulic pressure relief valve 7, and the push block 5 is pushed back to the right by the hydraulic pressure relief valve 7.

[0022] like Figures 3 to 5 As shown, a baffle is provided on the top of the vehicle body 1, a slide groove is opened in the middle of the vehicle body 1 and a sliding push-pull block 6 slides inside it, the reduction motor 2 is used to drive the lead screw 3 to rotate, so that the lead screw 3 drives the push block 5 to slide on the support rod 4, the lead screw 3 and the support rod 4 are located inside the sliding push-pull block 6, and the lead screw 3 and the support rod 4 are distributed in a stable triangle.

[0023] By setting a baffle on the top of the vehicle body 1, the blocks can be kept stable during transportation, and the blocks can be kept neat during loading to achieve the maximum loading capacity and reduce the transportation process. A slide groove is opened in the middle of the vehicle body 1 and the sliding push-pull block 6 slides inside it, so that the sliding push-pull block 6 can move freely at both ends of the vehicle body 1. The reduction motor 2 drives the lead screw 3 to rotate, so that the lead screw 3 drives the pushing block 5 to slide on the support rod 4, which can make the pushing block 5 drive the sliding push-pull block 6 to transport the blocks and maintain stability to avoid overturning and bumping. The lead screw 3 and the support rod 4 are arranged to have a stable triangular distribution, so that the pushing block 5 can maintain a stable and uniform speed when moving.

[0024] like Figures 2 to 5As shown, the pushing block 5 is located inside the sliding push-pull block 6 and is slidably connected to the sliding push-pull block 6. A friction layer is provided on the top of the sliding push-pull block 6. The sliding push-pull block 6 is located inside the limiting slide rail 9 and is slidably connected to the limiting slide rail 9. The extrusion limiting block 8 is located at the bottom of the limiting slide rail 9, and an inclined surface is provided on the upper end of the extrusion limiting block 8.

[0025] By setting a sliding push-pull block 6 and setting a friction layer on the top, the sliding push-pull block 6 can move the building blocks inside the vehicle body 1, and drive the building blocks located at the rear of the vehicle body 1 to the head position of the vehicle body 1, thereby reducing the manual handling process; the sliding push-pull block 6 is set inside the limiting slide rail 9 and is slidably connected to the limiting slide rail 9, so that the sliding push-pull block 6 can move synchronously with the limiting slide rail 9, and the sliding push-pull block 6 is driven to rise or fall by the limiting slide rail 9. When the hydraulic telescopic rod 7 pushes the extrusion limit block 8 to move, the inclined surface of the extrusion limit block 8 contacts the limiting slide rail 9 and squeezes and pushes the limiting slide rail 9 to move upward, so that the limiting slide rail 9 drives the sliding push-pull block 6 to move upward, so as to push the friction layer on the top of the sliding push-pull block 6 to the upper side of the vehicle body 1, so as to facilitate the sliding push-pull block 6 to drive the building blocks to move inside the vehicle body 1, so as to achieve convenient loading.

[0026] The working principle and use process of the utility model are as follows: when in use, first start the reduction motor 2 to drive the lead screw 3 to rotate, then the lead screw 3 drives the push block 5 to slide, and then the sliding push-pull block 6 moves to the rear of the vehicle body 1, and then the hydraulic telescopic rod 7 is started to push the extrusion limit block 8 to close in the middle, and the inclined surface of the extrusion limit block 8 contacts the limit slide rail 9 and squeezes and pushes the limit slide rail 9 to move upward, and then the limit slide rail 9 drives the sliding push-pull block 6 to move upward, so that the friction layer on the top of the sliding push-pull block 6 extends out of the top surface of the vehicle body 1, and then the block can be placed in the middle position Place it on the sliding push-pull block 6, start the reduction motor 2 again, the reduction motor 2 drives the screw 3 to rotate in the opposite direction, and then the screw 3 drives the pushing block 5 to move in the opposite direction, so that the sliding push-pull block 6 drives the building block to move to the inner side of the vehicle body 1, reducing labor costs and avoiding damage to the building blocks due to bumps during manual transportation, which affects the quality of the building blocks. After loading is completed, start the hydraulic telescopic rod 7 to pull the extrusion limit block 8 to move to both sides, so that the extrusion limit block 8 releases the extrusion limit on the limit slide rail 9, and then the limit slide rail 9 drives the sliding push-pull block 6 to move downward and reset.
