Description

Technical Field

[0001] The utility model belongs to the field of vehicle transportation equipment, in particular to a vehicle tarpaulin laying device. Background Art

[0002] After loading cargo on large vehicles, tarpaulins are usually placed on the roof to protect against rain and prevent the cargo in the truck bed from getting wet. Manual operation is often used to tie the tarpaulin to cover the roof. The common vehicle tarpaulins on the market currently have great safety hazards when operated manually, and personnel are prone to falling. The tarpaulin is easily torn due to uneven force during the tarpaulin covering process. The operation time is too long and the work efficiency is low. Some gantry frames are used for traction, but the fixed gantry frame cannot match vehicles of different heights well and does not have the function of facilitating the adjustment of the frame height. Secondly, when the tarpaulin towed by the gantry is moving, the accuracy of the vehicle's parking position is difficult to control, and the front and rear ends of the tarpaulin are not easy to align with the front and rear ends of the car during the laying process. This may cause the tarpaulin to fail to be laid or workers still need to manually adjust it repeatedly after laying. The operation is still relatively inconvenient, which is not conducive to improving the efficiency of tarpaulin laying. Utility Model Content

Those skilled in the art can select a suitable transverse crane 5 and its installation method according to actual needs to achieve the movement and lifting of the outer longitudinal beam 8, which will not be repeated here. At the same time, the lifting mechanism 3 can adopt existing lifting equipment, such as an elevator, etc. Those skilled in the art can also adopt other lifting mechanisms 3 according to actual needs to achieve the lifting of the inner longitudinal beam 2 with the outer longitudinal beam 8, which will not be repeated here.

[0030] The inner longitudinal beam 2 and the outer longitudinal beam 8 are both provided with a plurality of hook mechanisms for hooking the tarpaulin 9, and the hook mechanism includes a sliding seat 6 and a hook member 7 arranged on one side of the sliding seat 6, and the sliding seat 6 is correspondingly provided with an upper roller 13 and a lower roller 14, and there is a matching gap between the upper roller 13 and the lower roller 14 for matching with the inner longitudinal beam 2 or the outer longitudinal beam 8, and the left and right ends of the inner longitudinal beam 2 and the outer longitudinal beam 8 are both provided with limit blocks 19 for limiting the movement of the hook mechanism; a mounting seat 11 for mounting the lower roller 14 is provided below the sliding seat 6, and one side of the mounting seat 11 is detachably mounted on the sliding seat 6, and the other side is detachably connected to the hook member 7.

[0031] Exemplarily, two, four or more hook mechanisms may be arranged at intervals, and those skilled in the art may make reasonable arrangements according to the length of the vehicle 10 to achieve stable hooking of the tarpaulin 9, thereby ensuring that the inner longitudinal beam 2 and the outer longitudinal beam 8 can stably drive the tarpaulin 9 to rise and fall, which will not be elaborated here.

[0032] Optionally, at least two upper rollers 13 are arranged at intervals, and each upper roller 13 is rotatably mounted on the sliding seat 6. Exemplarily, two upper rollers 13 can be arranged, and each upper roller 13 can be rotatably mounted on the sliding seat 6 through a rotating shaft. By providing two upper rollers 13, it is beneficial to improve the stability of the movement of the sliding seat 6.

[0033] In actual application, at least two lower rollers 14 are arranged at intervals, and each upper roller 13 is rotatably mounted on the mounting seat 11. Exemplarily, two lower rollers 14 can be arranged corresponding to the upper rollers 13, and each lower roller 14 is rotatably mounted on the mounting seat 11 through a rotating shaft. By providing multiple lower rollers 14, it is not only beneficial to further improve the horizontal stability of the movement of the sliding seat 6, but also by using the cooperation of the lower rollers 14 and the lower rollers 14, it is also possible to ensure the vertical stability of the sliding seat 6, prevent the sliding seat 6 from falling from the outer longitudinal beam 8 or the inner longitudinal beam 2, and is beneficial to improve the safety and reliability of this laying device when laying the tarpaulin 9.

[0034] Optionally, the limit block 19 is fixed on the inner longitudinal beam 2 or the outer longitudinal beam 8. By setting the limit block 19, the limit block 19 can play a good limiting role on the hook mechanism, preventing the sliding seat 6 from accidentally moving out of the inner longitudinal beam 2 or the outer longitudinal beam 8, which is conducive to further improving the safety and reliability of this device when laying the tarpaulin 9. In addition, by detachably mounting one side of the mounting seat 11 on the sliding seat 6 and detachably connecting the other side to the hook member 7, the operator can disassemble and assemble the sliding seat 6 by disassembling the mounting seat 11, which is easy to operate; and by connecting the end of the hook member 7 to the sliding seat 6 using the mounting seat 11, it is also conducive to further improving the stability of the hook member 7 on the sliding seat 6, ensuring that the hook member 7 can continuously and stably hook the tarpaulin 9.

[0035] Optionally, the inner longitudinal beam 2 and the outer longitudinal beam 8 adopt hollow rod-shaped structural members, and the upper roller 13 and the lower roller 14 are provided with guide grooves 18 that cooperate with the hollow rod-shaped structural members. Exemplarily, the inner longitudinal beam 2 and the outer longitudinal beam 8 can both adopt hollow square tubes. By adopting hollow rod-shaped structural members, it is helpful to reduce the weight of the inner longitudinal beam 2 and the total weight of the outer side. In addition, by providing the guide grooves 18 that cooperate with the hollow rod-shaped structural members on the upper roller 13 and the lower roller 14, the guide grooves 18 cooperate with the hollow rod-shaped structural members, so that the lateral direction of the sliding seat 6 can be ensured, and the upper roller 13 and the lower roller 14 can be moved more stably along the longitudinal beam.

[0036] Optionally, the mounting seat 11 is connected to the sliding seat 6 via a fixing bolt 15, wherein at least two fixing bolts 15 are arranged at intervals, and each fixing bolt 15 is arranged vertically. Exemplarily, two or three fixing bolts 15 may be arranged at intervals, and a bolt hole matching the fixing bolt 15 may be provided on the mounting seat 11, and a threaded hole matching the fixing bolt 15 may be provided on the sliding seat 6. Those skilled in the art may also select a suitable method to install the fixing bolt 15 according to actual needs, so as to realize the detachable installation of the mounting seat 11 on the sliding seat 6, which will not be described in detail here.

[0037] In actual application, the hook member 7 is connected to the mounting seat 11 through a connecting bolt 16, and the connecting bolt 16 is arranged horizontally. The mounting seat 11 is provided with an assembly groove 17 that matches the hook member 7, the connecting bolt 16 is arranged corresponding to the assembly groove 17, the hook member 7 is provided with an installation hole that matches the connecting bolt 16, and the mounting seat 11 is provided with a threaded hole that matches the connecting bolt 16.

[0038] By using the vertically arranged fixing bolts 15 and the horizontally arranged connecting bolts 16 to respectively limit the two sides of the mounting seat 11, it is beneficial to improve the structural stability of the mounting seat 11 and prevent the mounting seat 11 from loosening and falling. In addition, by providing an assembly groove 17 on the mounting seat 11 to cooperate with the hook member 7, the mounting seat 11 and the hook member 7 can be plugged together, which is not only beneficial to further improve the stability of the mounting seat 11, but also beneficial to improve the structural strength of the connection between the mounting seat 11 and the hook member 7.

[0039] Optionally, the hook member 7 is detachably mounted on the sliding seat 6. Exemplarily, the hook member 7 can be fixed on the sliding seat 6 by screws. By detachably mounting the hook member 7, the operator can select a suitable hook member 7 for installation according to actual needs, so as to better hook the tarpaulin 9 and prevent the tarpaulin 9 from falling during the laying process, thereby improving the applicability and versatility of the laying device.

[0040] During actual use, one end of the hook member 7 can be fixed on the sliding seat 6 by screws, and the other end can be connected to the sliding seat 6 through the mounting seat 11. A stable annular structure can be formed between the sliding seat 6, the hook member 7, and the mounting seat 11. The annular structure is sleeved on the inner longitudinal beam 2 or the outer longitudinal beam 8, and is not prone to falling or deflection, which is beneficial to further improve the stability of the hook mechanism during movement.

[0041] Optionally, a driver 12 for driving the upper roller 13 to rotate is provided on the sliding seat 6. Exemplarily, the driver 12 can be a driving motor, and the power supply and control methods of the driving motor are all existing technologies, so they are not repeated here. Among them, the upper roller 13 can be connected to the output end of the driver 12 to realize the use of the driver 12 to drive the upper roller 13 to rotate. By using the driver 12 to drive the upper roller 13 to rotate, it is possible to drive the sliding seat 6 to move on the inner longitudinal beam 2 or the outer longitudinal beam 8, so that the tarpaulin 9 can be fine-tuned, and the multi-dimensional adjustment of the tarpaulin 9 (i.e., lifting adjustment, lateral movement adjustment, and longitudinal movement adjustment) is realized to realize the layout of the vehicle 10 with an inaccurate parking position, which is more convenient to operate and is conducive to improving the layout efficiency and layout effect of the tarpaulin 9.

[0042] Specifically, when using the vehicle tarpaulin laying device, the following steps can be referred to:

[0043] Step 1: First, place the inner and outer longitudinal beams on the ground, then hook the tarpaulin on the hook mechanism, and use the tarpaulin's own gravity to stably hook the tarpaulin on the hook. By placing the inner and outer longitudinal beams on the ground, operators do not need to work at height, and installing the tarpaulin is more convenient and safer.

[0044] Step 2: Lift the inner and outer longitudinal beams upwards and move the vehicle to the position below the cantilever so that one side of the vehicle is placed close to the inner longitudinal beam. Then, use the transverse overhead crane to drive the outer longitudinal beam to move transversely to achieve the transverse expansion of the tarpaulin, and use the driver to drive the sliding seat to expand longitudinally to both sides until the tarpaulin can cover the vehicle. By using the driver to drive the sliding seat to move, the tarpaulin can be adjusted longitudinally so that the unfolded tarpaulin is aligned with the position of the car body, so that the tarpaulin can directly cover the car body during the subsequent tarpaulin lowering process.

[0045] Step 3: Move the inner and outer longitudinal beams downward so that the tarpaulin can cover the car body. During the downward movement of the inner and outer longitudinal beams, the hook rings on the tarpaulin can be separated from the hook parts, and at this time the front and rear ends of the tarpaulin can be aligned with the car body, so the tarpaulin is not easy to slip. The operator only needs to make simple adjustments to complete the laying of the tarpaulin.

[0046] The vehicle tarpaulin laying device described in the utility model has a simple structure, is easy to use, has a good laying effect on the tarpaulin, is conducive to improving the laying efficiency of the vehicle tarpaulin, and reduces the labor intensity of operators. By adopting a method of cooperating with the liftable inner longitudinal beam and the outer longitudinal beam, it can be well adapted to vehicles of different heights. At the same time, by arranging a transverse overhead crane on the cantilever for driving the outer longitudinal beam to move laterally, and arranging a hook mechanism on the outer longitudinal beam and the inner longitudinal beam, the hook mechanism can also be used to realize the longitudinal adjustment of the tarpaulin position, so that the tarpaulin can cover the vehicle more conveniently, reducing the difficulty of subsequent adjustments by operators and improving the laying efficiency of the tarpaulin.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
