[0042] The fixing mechanism includes:

[0043] A fixing seat 15 is arranged at the top of the clamping plate 12, a matching groove 16 for clamping the fixing seat 15 is formed in the edge of the pressing plate 13, and a fixing groove 17 is formed in the inner side of the fixing seat 15, one end of the fixing groove 17 penetrates the edge of the fixing seat 15, and the other end is located in the fixing seat 15.

[0047] The middle part of the integral piece 21 is provided with an operating piece 24, the operating piece 24 is T-shaped, and the plane where the operating piece 24 is located is coplanar with the plane where the integral piece 21 is located.

[0048] The fixed groove 17 comprises a horizontal clamping groove 17a and an inclined anti-falling groove 17b, the bottom of the anti-falling groove 17b communicates with the inner end of the clamping groove 17a, and the fixed rod 18 abuts against the inner wall at the top end of the anti-falling groove 17b.

[0049] Further comprising a guide frame 25, the top of the guide frame 25 is horizontally provided with a guide cylinder 26, the guide cylinder 26 is located between the traction cylinder 3 and the support table 1, and the traction cable 4 movably passes through the guide cylinder 26.

[0050] The tarpaulin traction device provided by the utility model, when the tarpaulin is traction, first, the worker needs to manually traction or move the clamping mechanism to the end close to the tarpaulin roll of the support table 1, then the free end of the tarpaulin is clamped by using the clamping mechanism, and then the motor 5 drives the traction cylinder 3 to rotate, the traction cylinder 3 winds the traction cable 4, the traction cable 4 tractions the clamping mechanism through the first connecting cable 6 and the second connecting cable 7, and the tarpaulin can move along the direction of the support table 1 and move towards the traction cylinder 3; when the tarpaulin moves to the required length, the traction is stopped, and the clamping mechanism is separated from the tarpaulin; wherein since the tarpaulin does not need to be manually traction by the worker, the operation strength is small.

[0051] It should also be understood that the support table 1 is porous, and a plurality of negative pressure covers are arranged below the support table 1 for adsorbing and attaching the tarpaulin on the support table 1; meanwhile, the tarpaulin, the tarpaulin roll and the tarpaulin frame are not the range and object required to be protected by the application, and are not described and limited too much here.

[0052] In actual operation, the clamping plate 12 is moved to the end of the support table 1 close to the tarp roll, the tarp is laid on the clamping plate 12 close to the end, the first pressing plate 13 is placed horizontally on the top of the clamping plate 12, and the tarp is pressed on the clamping plate 12 by the pressing plate 13; then the free end of the tarp is wound around the pressing plate 13, and the second pressing plate 13 is placed; then the free end of the tarp is wound around the second pressing plate 13, and the third pressing plate 13 is placed, until all the pressing plates 13 are placed;

[0053] Then the fixing rod 18 is moved by the operating member 24, and the fixing rod 18 is inserted into the anti-dropping groove 17b through the clamping groove 17a; after the fixing rod 18 reaches the top of the anti-dropping groove 17b, the operating member 24 is rotated, and the rotating arm 20, the fixing rod 18, the cam body 19, etc. are rotated at the same time; until the adsorption part 22 (stainless steel material) is adsorbed on the magnetic body 23 (magnet, embedded in the top pressing plate 13), at this time, the end of the cam body 19 farthest from the fixing rod 18 is vertically pressed on the top of the top pressing plate 13; because the magnetic body 23 has magnetic attraction to the adsorption part 22, the angle and position of the cam body 19 can be guaranteed, so that each pressing plate 13 can stably maintain its position. In actual use, the pressing plate 13 applies a vertical upward force to the cam body 19 and the fixing rod 18, so the magnetic attraction force between the magnetic body 23 and the adsorption part 22 is required to be low.

[0054] In the process of pulling the tarp, the tarp is not only subjected to the pressing action of the clamping plate 12 and the pressing plate 13, but also has a wave shape between the clamping plate 12 and the pressing plate 13, so that the relative motion resistance of the tarp and the clamping plate 12 and the pressing plate 13 is greatly improved (the tarp is relatively hard), so that the tarp can be stably pulled forward. Moreover, the pressing plate 13 and the clamping plate 12 can maintain sufficient relative position stability through the fixing seat 15 and the guide column 14.

[0055] During the rotation of the traction cylinder 3, the traction cable 4 will first pass through the guide cylinder 26 and then be wound on the traction cylinder 3, so that the traction direction of the traction cable 4 is stable, and the traction direction of the tarpaulin is ensured. During actual traction, even if the clamping plate 12 is not in parallel with the edge of the tarpaulin, for example, the clamping plate 12 has a certain inclination angle relative to the support table 1. At this time, during traction, since the traction cable 4 does not directly pull the first and second connecting cables 6 and 7, but drives the first and second connecting cables 6 and 7 through the movable frame 8 and the movable wheel 9, if the clamping plate 12 has a certain inclination, the first and second connecting cables 6 and 7 can move relative to the movable wheel 9 at this time, and the clamping plate 12 can stably pull the tarpaulin forward, preventing one side of the tarpaulin from bearing excessive tension and being damaged, etc., ensuring the structural integrity of the tarpaulin, and also enabling the tarpaulin to fully move forward without being deviated by traction. Furthermore, the first and second connecting cables 6 and 7 are movably clamped in the limiting groove 10, and the anti-disengagement part 11 can limit the first and second connecting cables 6 and 7, so that the first and second connecting cables 6 and 7 can stably interact with the movable wheel 9.

[0056] After the tarpaulin is pulled to the appropriate position, the operating part 24 is only rotated upward, the adsorption part 22 is separated from the magnetic body 23, the fixed rod 18 is disengaged along the anti-disengagement groove 17b and the clamping groove 17a, and then the pressing plate 13 is separated upward, so that the tarpaulin is separated from the clamping plate 12.

[0057] The downstream end of the support table 1 has a temporary support table. If the tarpaulin needs to be pulled to cover the entire support table 1, the clamping plate 12 can be moved to the temporary support table for support after the tarpaulin is separated from the clamping plate 12, without hindering the cutting of the tarpaulin.

[0058] In another embodiment, the clamping plate 12 has a movable wheel 9 at the bottom, and movable grooves are provided at the top of both sides of the support table 1. The movable wheel 9 is movably located in the movable groove, which not only reduces the movement resistance of the clamping plate 12, but also guides the clamping plate 12. At the same time, the clamping plate 12 can be moved to the position of clamping the tarpaulin more easily.

[0059] In another embodiment, the free end of the traction cable 4 is fixedly connected with the free ends of the first and second connecting cables 6 and 7.

[0060] The above description is only a description of the preferred embodiment of the present application, and does not limit the scope of the present application. Any modification or modification of the above disclosure by a person skilled in the art is within the protection scope of the claims.
