[0027] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0028] A lifting device for laying a tarpaulin 6 on a vehicle, such as Figures 1 to 4 As shown, it includes a support frame 1, a cantilever 2 arranged on the support frame 1, and a longitudinal beam 4 arranged on the cantilever 2. The cantilever 2 is provided with a transverse overhead crane 3 for driving the longitudinal beam 4 to rise, fall and move.

[0029] Specifically, two cantilevers 2 can be arranged at intervals, and each cantilever 2 is fixedly mounted on the support frame 1, wherein the transverse crane 3 is installed on the cantilever 2, and the lifting end of the transverse crane 3 is connected to the longitudinal beam 4. Technical personnel in this field can select a suitable transverse crane 3 and its installation method according to actual needs to realize the movement and lifting of the longitudinal beam 4, which will not be repeated here.

[0030] In actual application, in order to better lay out the sheet 6, two longitudinal beams 4 can be provided, and two corresponding transverse cranes 3 can be provided to realize the movement and lifting of the longitudinal beam 4, so that the operator can use the two longitudinal beams 4 to respectively hoist the two ends of the sheet 6 to improve the stability of the hoisting and laying of the sheet 6. Those skilled in the art can also adjust the number of longitudinal beams 4 and transverse cranes 3 according to actual needs to realize the hoisting and laying equipment of the sheet 6, which will not be repeated here.

[0031] The longitudinal beam 4 is provided with a clamping mechanism 5 for clamping the tarpaulin 6, and a plurality of the clamping mechanisms 5 are arranged at intervals, and each clamping mechanism 5 includes a mounting seat 8 and a clamping assembly arranged on the mounting seat 8, and the clamping assembly includes a cam 12 and a clamping wheel 11 for clamping the tarpaulin 6 in cooperation with the cam 12, and the cam 12 is rotatably mounted on the mounting seat 8, and the mounting seat 8 is provided with a driver 16 for driving the cam 12 to rotate; the mounting seat 8 is provided with a mounting frame 10 for mounting the clamping wheel 11, and there is an accommodating gap between the mounting frame 10 and the mounting seat 8 for accommodating the end of the tarpaulin 6, and the clamping wheel 11 is rotatably mounted on the mounting frame 10.

[0032] Exemplarily, two, four or more clamping mechanisms 5 may be arranged at intervals, and those skilled in the art may arrange them reasonably according to the length of the vehicle 7 to achieve stable clamping and limiting of the tarpaulin 6, thereby ensuring that the longitudinal beam 4 can stably drive the tarpaulin 6 to rise, fall and move, which will not be elaborated here.

[0033] In actual application, the cam 12 can be rotatably mounted on the mounting seat 8 via a rotating shaft, and a bearing seat for mounting the rotating shaft is fixedly mounted on the mounting seat 8. Similarly, the clamping wheel 11 can also be rotatably mounted on the mounting frame 10 via a rotating shaft, and a bearing seat for mounting a bearing can also be fixedly mounted on the mounting frame 10. In addition, those skilled in the art can also select a suitable method to install the cam 12 and the clamping wheel 11 according to actual needs to achieve stable rotational cooperation between the two, so that the raised portion of the cam 12 can cooperate with the clamping wheel 11 to achieve clamping and fixing of the sheet 6, which will not be repeated here.

[0034] Optionally, the driver 16 can adopt an existing drive motor or servo motor, and the power supply control method of the drive motor or servo motor is an existing technology, so it is not repeated here. Among them, the cam 12 can be connected to the output end of the driver 16 to realize the use of the driver 16 to drive the cam 12 to rotate.

[0035] In actual application, the operator uses the driver 16 to drive the cam 12 to rotate, thereby clamping and fixing the tarpaulin 6 or releasing the clamping of the tarpaulin 6. The operation is simpler and the operator no longer needs to manually fix the tarpaulin 6. The operator only needs to place the end of the tarpaulin 6 in the accommodating gap and then use the driver 16 to rotate the cam 12. The protrusion on the cam 12 can cooperate with the clamping wheel 11 to clamp and fix the tarpaulin 6, which reduces the operating difficulty and labor intensity of the operator and is conducive to improving the laying efficiency of the tarpaulin 6.

[0036] In addition, by utilizing the cooperation between the cam 12 and the clamping wheel 11, and arranging a driver 16 on the mounting seat 8 for driving the cam 12 to rotate, when the driver 16 drives the cam 12 to rotate, the cam 12 can also push the tarpaulin 6 further into the accommodating gap, which is conducive to the cam 12 and the clamping wheel 11 to better clamp and fix the end of the tarpaulin 6, thereby preventing the tarpaulin 6 from falling off during the subsequent lifting process.

[0037] Optionally, the mounting frame 10 is slidably mounted on the mounting seat 8 so that the clamping wheel 11 can cooperate with the cam 12 to clamp the sheets 6 of different thicknesses. Exemplarily, the mounting frame 10 is slidably mounted on the mounting seat 8 via a guide rod 17, and the mounting seat 8 is provided with a guide hole 18 that slidably cooperates with the guide rod 17, and one end of the guide rod 17 that passes through the guide hole 18 is provided with a limiter 14, and an elastic element 13 is provided on the guide rod 17 at a position corresponding to the position between the mounting seat 8 and the limiter 14, and one end of the elastic element 13 abuts the mounting seat 8, and the other end abuts the limiter 14.

[0038] In actual application, the limiter 14 is fixed on the guide rod 17, and the guide rod 17 and the mounting frame 10 can be connected by threads to facilitate the assembly of the elastic element 13. In addition, the limiter 14 and the guide rod 17 can also be connected by threads, and the guide rod 17 is fixed on the mounting frame 10. Those skilled in the art can choose a suitable method to realize the assembly of the elastic element on the guide rod 17, which will not be repeated here. By adopting a threaded connection, it is also convenient for the operator to screw and adjust the guide rod 17 or the limiter 14 according to actual needs, so as to adjust the resetting elastic force of the elastic element 13, which is conducive to improving the coordination effect between the cam 12 and the clamping wheel 11, and preventing the tarpaulin 6 from being damaged due to excessive clamping force between the cam 12 and the clamping wheel 11.

[0039] Optionally, the elastic element 13 is a compression spring. Exemplarily, the compression spring can be sleeved on the guide rod 17. Those skilled in the art can select a compression spring with a suitable elastic force according to actual needs, or can use other suitable elastic elements 13 to achieve the sliding limit of the mounting frame 10, which will not be repeated here.

[0040] Optionally, at least two guide rods 17 are arranged at intervals. Exemplarily, two, three or more guide rods 17 can be arranged at intervals. By providing multiple guide rods 17, it is beneficial to improve the sliding stability of the mounting frame 10.

[0041] In actual use, by sliding the mounting frame 10 on the mounting seat 8 using the guide rod 17, the clamping mechanism 5 can achieve the clamping of the tarpaulins 6 of different thicknesses, and the clamping effect is good, and the tarpaulins 6 are not easily damaged. At the same time, by arranging the elastic element 13 on the guide rod 17, the elastic element 13 can not only play a good limiting role on the mounting frame 10, preventing the mounting frame 10 from falling off the mounting seat 8, but also ensure that the clamping wheel 11 on the mounting frame 10 can stably cooperate with the cam 12 to achieve the clamping and fixing of the tarpaulin 6. In addition, the elastic element 13 can also play a good buffering and protective role. When the protrusion on the cam 12 cooperates with the clamping wheel 11 to achieve the clamping of the tarpaulin 6, if the clamped tarpaulin 6 is thicker, the cam 12 can drive the mounting frame 10 to slide by pushing the clamping wheel 11, thereby reducing the clamping force at the cam 12 and the clamping wheel 11, and preventing the tarpaulin 6 from being damaged.

[0042] Optionally, anti-skid patterns are provided on the clamping wheel 11 and the cam 12. The anti-skid patterns are provided to increase the friction between the clamping wheel 11 and the cam 12 and the sheet 6, and to further improve the clamping and fixing effect of the clamping wheel 11 and the cam 12 on the sheet 6.

[0043] In actual application, the cam 12 and the clamping wheel 11 are both made of rubber or silicone. The cam 12 and the clamping wheel 11 made of rubber or silicone have better deformation and buffering properties, and can better protect the sheet 6, and prevent the sheet 6 from being damaged due to extrusion. At the same time, the cam 12 and the clamping wheel 11 can also achieve buffering through elastic deformation and cooperation with the elastic element 13, further reducing the possibility of damage to the sheet 6 due to extrusion.

[0044] Optionally, the mounting seat 8 is slidably mounted on the longitudinal beam 4, and a driving component 9 for driving the mounting seat 8 to move is provided on the mounting seat 8. Exemplarily, a track wheel 15 cooperating with the longitudinal beam 4 is rotatably mounted on the mounting seat 8, and a bearing seat for mounting the track wheel 15 is fixed on the mounting seat 8. Among them, the driving component 9 can adopt an existing driving motor, and the output end of the driving motor is connected to the track wheel 15, so as to realize the use of the driver 16 to drive the track wheel 15 to rotate, and then determine that the mounting seat 8 is moved and adjusted on the longitudinal beam 4; the power supply control method of the driving motor is all existing technology, which will not be repeated here. In addition, those skilled in the art can also select other suitable driving components 9 according to actual needs to realize the stable movement of the mounting seat 8 on the longitudinal beam 4, which will not be repeated here.

[0045] In actual use, by utilizing the driving assembly 9 to drive the mounting base 8 to move, the longitudinal position of the tarpaulin 6 can be fine-tuned, thereby realizing multi-dimensional adjustment of the tarpaulin 6 (i.e., lifting adjustment, lateral movement adjustment, and longitudinal movement adjustment), so that this lifting equipment can accurately lay out the tarpaulin 6 on the vehicle 7, and the operation is simpler, which is conducive to improving the laying efficiency and laying effect of the tarpaulin 6.

[0046] Specifically, when using this vehicle tarpaulin installation hoisting equipment, the following steps can be followed: Step 1, first place the longitudinal beam on the ground, then load the tarpaulin on the clamping mechanism, and use the driver to drive the cam to rotate so that the protrusion on the cam cooperates with the clamping wheel to clamp and fix the end of the tarpaulin. By placing the longitudinal beam on the ground, the operator does not need to work at a height, and the installation of the tarpaulin is more convenient and safer.

[0047] Step 2: Lift the longitudinal beam upward 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 lateral overhead crane to drive the longitudinal beam to move horizontally to achieve the lateral expansion of the tarpaulin. At the same time, use the drive assembly to drive the mounting seat to expand or fine-tune it longitudinally on both sides until the tarpaulin can cover the vehicle. By using the drive assembly to drive the mounting 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.

[0048] Step three, move the longitudinal beam downward so that the cloth can cover the car body. During the downward movement of the longitudinal beam, the operator can use the driver to reset the cam. The raised part of the cam separates from the clamping wheel and releases the clamping fixation on the end of the tarpaulin. At this time, the front and rear ends of the tarpaulin can be aligned with the car body, and the tarpaulin is not easy to slip. The operator only needs to make simple adjustments to complete the laying of the tarpaulin.

[0049] The utility model discloses a hoisting device for laying vehicle tarpaulins, which has the advantages of being easy to use and operate, and can be used for the rapid hoisting and laying of vehicle tarpaulins, with good laying effect and high laying efficiency. By utilizing the cooperation of the cam and the clamping wheel, and arranging a driver for driving the cam to rotate on the mounting seat, when the driver drives the cam to rotate, the raised portion on the cam can cooperate with the clamping wheel to achieve the clamping and fixing of the tarpaulin, which reduces the operating difficulty and labor intensity of the operator, and is conducive to improving the laying efficiency of the tarpaulin; and the rotating cam can also further push the tarpaulin into the accommodating gap, which is conducive to the cam and the clamping wheel to better clamp and fix the end of the tarpaulin, and prevent the tarpaulin from falling off during the subsequent hoisting process.

[0050] 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.
