Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary devices for installing truck tarpaulins, and in particular to a vertical lifting truck tarpaulin machine. Background Technology

[0002] Truck tarpaulin covering and installation technology was developed to address the need for cargo protection during truck transportation. During cargo transport, proper covering and protection are essential to ensure the safety, integrity, and protection of goods from external environmental influences. Tarpaulins, as a common covering material, are lightweight, durable, and easy to operate, thus widely used in truck transportation. Currently, installing tarpaulins on trucks involves workers climbing onto the truck with auxiliary tools, a complex process that increases the workload. Therefore, designing a vertical lifting tarpaulin covering machine to solve these technical problems is particularly important. Utility Model Content

[0003] The purpose of this utility model is to solve the problem that the installation of tarpaulins used to cover and protect goods on existing trucks requires workers to climb onto the truck with auxiliary tools, which is a complicated process and increases the workload of workers. Therefore, a vertical lifting truck tarpaulin machine is proposed.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a vertical lifting vehicle covering machine, comprising a support frame, wherein the support frame is arranged in multiple sets symmetrically on the left and right, a shielding frame is installed on the top of the support frame, a truck is movably arranged below the shielding frame, fixed pulleys are installed on the top and bottom of the left and right adjacent support frames, the upper and lower fixed pulleys are connected by chains, and a reduction motor is installed on each of the left and right adjacent top fixed pulleys, the output end of the reduction motor drives the fixed pulley to rotate, and the left and right reduction motors are uniformly controlled by the operator.

[0005] Preferably, a slide is installed on both sides of the chain, a movable pulley is installed on the slide, and a guide pulley is also installed below the movable pulley on the slide.

[0006] Preferably, the movable pulley is disposed between the chains to drive the carriage to move longitudinally in the chain direction, and the guide pulley is disposed on one side of the chain to assist the carriage's displacement.

[0007] Preferably, the carriage is equipped with crossbars, and tarpaulins are draped between adjacent crossbars. Iron blocks are fastened to the tarpaulins, and electromagnets are installed on each crossbar.

[0008] Preferably, the carriage has an L-shaped cross-section.

[0009] Preferably, the length of the tarpaulin is adjusted to accommodate the length of the truck to be covered.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] 1. In this utility model, during use, a shielding frame structure is installed on the top of the support frame, and then a reduction motor is installed on the support frames on both sides. The reduction motor drives the fixed pulley at the top, which in turn drives the fixed pulley at the bottom to rotate with the chain. The slide frame, in conjunction with the movable pulley, slides up and down on the chain. The guide pulley slides on the chain to provide guidance and assistance. The iron block on the tarpaulin, in conjunction with multiple sets of electromagnets on the crossbar, completes the limiting and fixing work of the tarpaulin on the crossbar. With the cooperation of the slide frame, the tarpaulin achieves the up and down sliding work. Compared with the conventional method of having workers climb onto the truck with auxiliary tools to install the tarpaulin, the technical solution adopted by this utility model can realize the semi-automatic covering and installation of tarpaulins on trucks. The overall structure is compact, the space layout is reasonable, and it is easy for workers to install and maintain. It solves the problem that the existing tarpaulin installation on trucks, which is used to cover and protect goods, requires workers to climb onto the truck with auxiliary tools for installation and fixing, which is complicated and increases the labor burden of workers. 2. In this utility model, during use, the worker manually attracts and limits the iron block on the tarpaulin to the electromagnet on the crossbar when it is energized, so that the tarpaulin is installed on the crossbar.

[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] This utility model provides a vertical lifting vehicle covering machine, including a support frame 1, which is arranged in multiple sets symmetrically on the left and right. A shielding frame 101 is installed on the top of the support frame 1, and a truck 2 is movably arranged below the shielding frame 101. Fixed pulleys 201 are installed on the top and bottom of adjacent left and right support frames 1, and the upper and lower fixed pulleys 201 are connected by a chain 202. A reduction motor 3 is installed on each of the adjacent left and right top fixed pulleys 201, and the output end of the reduction motor 3 drives the fixed pulleys 201. The rotation is controlled by the staff. Each of the two chains 202 has a slide 4 with an L-shaped cross-section. A movable pulley 401 is mounted on each slide 4, and a guide pulley 402 is mounted below the movable pulley 401 on the slide 4. The movable pulley 401 is positioned between the chains 202 to drive the longitudinal displacement of the slide 4 along the chain 202. The guide pulley 402 is positioned on one side of the chain 202 to assist the displacement of the slide 4.

[0019] In actual use, the vertical lifting tarpaulin machine is operated by the operator who manually engages the iron block 502 on the tarpaulin 501 with the energized electromagnet 503 on the crossbar 5, thus securing the tarpaulin 501 onto the crossbar 5. Then, the drive motors 3 on both sides begin operation, causing the top fixed pulley 201 to rotate clockwise. Since the top and bottom fixed pulleys 201 are connected by a chain 202, the rotation of the top fixed pulley 201, in conjunction with the chain 202, drives the bottom fixed pulley 201 to rotate. The chain 202's operation causes the slide frame 4 to slide upwards on the chain 202. The movable pulley 401 is positioned between the chains 202 to provide power for the slide carriage 4 to slide up and down. The guide pulley 402 on the slide carriage 4 slides to the left of the chain 202, guiding the slide carriage 4 during its movement and ensuring its orderly up-and-down movement on the chain 202. When the slide carriage 4 reaches the end of its upward stroke, the reduction motor 3 stops working. At this point, the driver drives the vehicle to a stop under the shield 101, then starts driving the reduction motors 3 on both sides, causing the top fixed pulley 201 to rotate counterclockwise. This, in conjunction with the chain 202, drives the bottom fixed pulley 201 to rotate, thus... The carriage 4 slides down the chain 202 from top to bottom until the tarpaulin 501 covers the truck 2. At this point, the control electromagnet 503 stops energizing, and the iron block 502 on the tarpaulin 501 falls off the crossbar 5. Then, the carriages 4 on both sides return to their original positions and move upwards. This completes the covering of the cargo on the truck 2. By installing a shielding frame 101 structure on the top of the support frame 1, and then installing a reduction motor 3 on both sides of the support frame 1, the reduction motor 3 drives the fixed pulley 201 at the top, which in turn drives the fixed pulley 201 at the bottom to rotate in conjunction with the chain 202. The carriage 4, in conjunction with the movable pulley 401, moves along the chain 202. The tarpaulin 501 slides up and down, guided by the guide pulley 402 sliding on the chain 202. The iron block 502 on the tarpaulin 501, together with the multiple sets of electromagnets 503 on the crossbar 5, completes the limiting and fixing work of the tarpaulin 501 on the crossbar 5. With the cooperation of the carriage 4, the tarpaulin 501 slides up and down. Compared with the conventional method of workers climbing onto the truck 2 with auxiliary tools to install the tarpaulin 501, the technical solution adopted by this utility model can realize the semi-automatic covering and installation of the tarpaulin 501 on the truck 2. The overall structure is compact, the space layout is reasonable, and it is easy for workers to install and maintain.

[0020] Example 1

[0021] like Figure 1-3 As shown, crossbars 5 are installed on the carriage 4, and tarpaulins 501 are overlapped between adjacent crossbars 5. Iron blocks 502 are fastened to the tarpaulins 501. Electromagnets 503 are installed on each crossbar 5. The length of the tarpaulins 501 is adjusted according to the length of the truck 2 to be covered.

[0022] The effect achieved by the entire embodiment 1 is that, during use, the operator manually attracts and limits the iron block 502 on the tarpaulin 501 to the energized electromagnet 503 on the crossbar 5, thus installing the tarpaulin 501 on the crossbar 5. Working principle: The operator manually attracts and limits the iron block on the tarpaulin to the energized electromagnet on the crossbar, thus installing the tarpaulin on the crossbar. Then, the reduction motors on both sides are driven to start working, driving the top fixed pulley to rotate clockwise. Since the top and bottom fixed pulleys are connected by a chain, the rotation of the top fixed pulley, in conjunction with the chain, drives the bottom fixed pulley to rotate. The chain operation causes the slide to slide upwards on the chain. The movable pulley structure on the slide is located between the chains to provide power for the slide's upward and downward movement. The guide pulley on the slide then slides on the left side of the chain, aligning with the sliding mechanism. The guide frame ensures the carriage slides up and down the chain in an orderly manner. When the carriage reaches the end of its upward stroke, the reduction motor stops working. At this time, the driver drives the vehicle under the cover frame and stops it. Then, the reduction motors on both sides start working, driving the top fixed pulley to start working counterclockwise. This, in conjunction with the chain, drives the bottom fixed pulley to start working, causing the carriage to slide down the chain from top to bottom until the tarpaulin covers the truck. At this time, the electromagnet stops being energized, and the iron block on the tarpaulin falls off the crossbar. Then, the two carriages on both sides return to their original positions and move upward. This completes the work of covering the cargo on the truck.
