Description

Technical Field

[0001] This utility model belongs to the field of vehicle canopy technology and relates to a traction unit for canopy ropes. Background Technology

[0002] During the construction of a carport, the first step is to erect a carport frame at the construction site, and then cover the top of the frame with the tarpaulin. Because the tarpaulin has a certain mass and area, in actual construction, a rope is first tied to one end of the tarpaulin, and then the other end of the rope is pulled across the top of the frame. Finally, the tarpaulin is pulled along by the rope.

[0003] Most tarpaulins are frame structures, mainly consisting of a bottom support structure and a crisscrossing structure at the top of the support structure, giving the frame sufficient strength. Because the top of the frame has a crisscrossing structure, the free end of the rope is typically passed over the frame using two methods. The first is to forcefully swing a small portion of the free end of the rope (manually by the worker) over a crossbeam, then pull down a certain length of rope, and then swing it over the next crossbeam until the free end of the rope has passed all the crossbeams. The second method is to wind the rope into a coil, then swing the entire coil over the crossbeam, release a certain length of rope, and then swing it over the next crossbeam until the rope has passed all the crossbeams. However, both methods are time-consuming and inefficient. Utility Model Content

[0004] The purpose of this invention is to provide a traction unit for tarpaulin ropes, which aims to solve the problem of low operating efficiency.

[0005] To solve the above-mentioned technical problems, this utility model provides a traction unit for tarpaulin ropes, comprising:

[0006] A vertical traction frame, with a traction column horizontally installed at the top of the traction frame;

[0007] The hinged column is horizontal and its length direction is perpendicular to the length direction of the traction column. When passing the frame beam, the traction column is lower than the frame beam and the hinged column is higher than the frame beam.

[0008] The linkage arm has its downstream end vertically hinged to the hinge column. The bottom of the upstream end of the linkage arm is provided with an actuating part at an incline. The free end of the actuating part faces the traction column. The bottom of the actuating part is provided with an arc-shaped first fastening part. The minimum distance between each part of the first fastening part and the hinge column is equal. The top of the traction column is provided with a first mating groove that mates with the first fastening part. The upstream end of the linkage arm is provided with a connecting ring for connecting a rope.

[0009] A swing arm, the top of which is fixedly connected to the hinge column, a swing seat is provided at the bottom of the swing arm, and arc-shaped second fastening parts are provided on both sides of the downstream end of the traction column. The distance between each of the second fastening parts and the hinge column is equal. The upstream end of the swing seat abuts against the downstream end of the traction column, and a second mating groove is provided on both sides to cooperate with the second fastening part.

[0010] An elastic element is connected to the swing arm and the linkage arm, and the swing arm and the linkage arm are continuously brought closer to each other.

[0011] The present invention is further configured such that two connecting ears are spaced apart at the top of the swing arm, both connecting ears are fixedly connected to the hinge post, and the hinge point between the linkage arm and the hinge post is located between the two connecting ears.

[0012] The present invention is further configured such that both sides of the linkage arm are movably fitted to the connecting ear.

[0013] The present invention is further configured such that the elastic element includes a first helical body, a second helical body, and a middle portion connected at both ends to the first helical body and the second helical body respectively. The middle portion is U-shaped. The first helical body and the second helical body are fixedly connected to both ends of the hinge column respectively. The middle portion of the middle portion movably abuts against the top of the linkage arm.

[0014] The present invention is further configured such that a translation frame is horizontally arranged at the bottom of the traction frame, and a translation wheel is rotatably arranged at the bottom of the translation frame.

[0015] The present invention is further configured such that the traction frame includes a bottom frame and a top frame. The bottom of the bottom frame is fixedly connected to the translation frame, and the top of the top frame is fixedly connected to the bottom of the traction column. A lifting hole with a convex cross-section is vertically opened through the middle of the bottom frame. The top frame has a rectangular cross-section, and all four sides of the top frame can be movably fitted against the inner wall of the lifting hole. Several cylindrical lifting parts are vertically distributed on the sides of the top frame, and all the lifting parts can pass through the lifting hole. A lifting plate is vertically rotatably arranged inside the bottom frame. A spiral part with a helical cross-section is provided on the inner side of the lifting plate. Any position of the spiral part can movably abut against any two adjacent lifting parts. An operating handle for rotating the lifting plate is provided on the outer side of the lifting plate.

[0016] Compared with the prior art, this utility model provides a traction unit for tarpaulin ropes. When traction, the traction end of the rope is first fixedly connected to the connecting ring. Then, the worker manually moves the position of the traction column using a traction frame, ensuring that the traction column at this position is lower than the crossbeam of the frame, while the hinge column and the linkage arm are higher than the crossbeam. Next, the traction frame is moved horizontally, causing the actuating part to act first on the side of the crossbeam. Because the actuating part is inclined, it moves upward during the movement, causing the linkage arm to swing upward, and the first engaging part disengages from the first mating groove until the first engaging part also passes the top of the crossbeam. At this point, the elastic element increases the force between the linkage arm and the swing arm, and also increases the resistance force between the swing arm and the hinge column, thus maintaining the stability of the swing arm's position and angle.

[0017] Once the first engaging part passes the top of the crossbeam, the elastic force of the elastic element causes the first engaging part to move toward the traction column until it is inserted into the first mating groove. At this point, although the rope applies a reaction force to the connecting ring, the distance between the connecting ring and the hinge column is very close, so the linkage arm cannot be rotated.

[0018] Continue moving the traction frame until the swing arm contacts the crossbeam. At this point, the crossbeam drives the swing arm and swing seat to swing upwards until both have passed the crossbeam. The plane containing the side of the swing arm closest to the first engagement part is coplanar with the plane containing the side of the swing seat closest to the first engagement part, which facilitates the swing arm and swing seat passing over the crossbeam. During this process, the force applied to the linkage arm and swing arm by the elastic element increases, ensuring the stability of the connection between the first engagement part and the traction column. Once the swing seat has passed the crossbeam, under the action of the elastic element and gravity, the swing seat returns to contact the downstream end of the traction column, and at this point, the free end of the rope has passed the top of the crossbeam.

[0019] In actual operation, the workers only need to move the traction frame forward. Each step is automatic, requiring no additional operation, thus simplifying the process and increasing efficiency. Furthermore, the entire traction rope operation relies solely on moving the traction frame, eliminating the need for rope swinging and resulting in better performance. Once the rope has completely passed the crossbeam, it is separated from the connecting ring, and the tarpaulin can then be pulled up to cover the entire frame using this rope.

[0028] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a more detailed explanation of the tarpaulin rope traction unit proposed in this utility model. The advantages and features of this utility model will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, used only to facilitate and clarify the illustration of the embodiments of this utility model. The same or similar reference numerals in the drawings represent the same or similar parts.

[0029] A tarpaulin rope traction unit, such as Figures 1 to 7 As shown, it includes:

[0030] A vertical traction frame 1, with a traction column 2 horizontally installed at the top of the traction frame 1;

[0031] The hinge column 3 is horizontal and its length direction is perpendicular to the length direction of the traction column 2. When passing the frame beam, the traction column 2 is lower than the frame beam and the hinge column 3 is higher than the frame beam.

[0032] Linkage arm 4, the downstream end of which is vertically hinged to hinge post 3, the bottom of the upstream end of linkage arm 4 is inclinedly provided with a working part 5, the free end of the working part 5 faces the traction post 2, the bottom of the working part 5 is provided with an arc-shaped first fastening part 6, the minimum distance between each part of the first fastening part 6 and the hinge post 3 is equal, the top of the traction post 2 is provided with a first mating groove 7 that mates with the first fastening part 6, and the upstream end of linkage arm 4 is provided with a connecting ring 8 for connecting ropes;

[0033] The swing arm 9 has its top fixedly connected to the hinge post 3, and its bottom is provided with a swing seat 10. Both sides of the downstream end of the traction post 2 are provided with arc-shaped second fastening parts 11. The distance between each of the second fastening parts 11 and the hinge post 3 is equal. The upstream end of the swing seat 10 abuts against the downstream end of the traction post 2, and both sides are provided with second mating grooves 12 that cooperate with the second fastening parts 11. A hole is provided at the top of the swing arm 9 for the connecting ring 8 to be inserted, so that when the swing arm 9 swings, the connecting ring 8 does not abut against the swing arm 9.

[0034] The elastic element 13 is connected to the swing arm 9 and the linkage arm 4, and makes the swing arm 9 and the linkage arm 4 continuously move closer to each other.

[0035] The top of the swing arm 9 is provided with two connecting ears 14 at intervals. Both connecting ears 14 are fixedly connected to the hinge post 3. The hinge point between the linkage arm 4 and the hinge post 3 is located between the two connecting ears 14.

[0036] Both sides of the linkage arm 4 are movably fitted to the connecting ear 14.

[0037] The elastic element 13 includes a first helix 13a, a second helix 13b, and a middle portion 13c whose two ends are respectively connected to the first helix 13a and the second helix 13b. The middle portion 13c is U-shaped. The first helix 13a and the second helix 13b are respectively fixedly connected to the two ends of the hinge post 3. The middle portion 13c moves against the top of the linkage arm 4.

[0038] The bottom of the traction frame 1 is horizontally provided with a translation frame 15, and the bottom of the translation frame 15 is rotatably provided with a translation wheel 16. The traction frame 1 includes a bottom frame 1a and a top frame 1b. The bottom of the bottom frame 1a is fixedly connected to the translation frame 15, and the top of the top frame 1b is fixedly connected to the bottom of the traction column 2. A lifting hole 17 with a convex cross-section is vertically opened through the middle of the bottom frame 1a. The top frame 1b has a rectangular cross-section, and all four sides of the top frame 1b can be movably fitted to the inner wall of the lifting hole 17. Several cylindrical lifting parts 18 are vertically distributed on the side of the top frame 1b. All the lifting parts 18 can pass through the lifting hole 17. A lifting plate 19 is vertically rotatably arranged inside the bottom frame 1a. A spiral part 20 with a spiral cross-section is provided on the inner side of the lifting plate 19. The spiral part 20 can move and abut against any two adjacent lifting parts 18 at any position. An operating handle 21 for rotating the lifting plate 19 is provided on the outer side of the lifting plate 19.

[0039] This utility model provides a tarpaulin rope traction unit. When traction, the traction end of the rope is first fixedly connected to the connecting ring 8. Then, the worker manually moves the position of the traction column 2 through the traction frame 1, so that the traction column 2 at this position is lower than the crossbeam of the frame, while the hinge column 3 and the linkage arm 4 are higher than the crossbeam of the frame. Then, the traction frame 1 is translated, so that the action part 5 first acts on the side of the crossbeam. Since the action part 5 is inclined, it will move upward during the movement, causing the linkage arm 4 to swing upward. The first fastening part 6 disengages from the first mating groove 7 until the first fastening part 6 also passes the top of the crossbeam. At this time, the elastic element 13 makes the force between the linkage arm 4 and the swing arm 9 greater, and also makes the contact force between the swing seat 10 and the hinge column 3 greater, so that the swing arm 9 continues to maintain its position and angle stability.

[0040] Once the first engaging part 6 passes the top of the crossbeam, the elastic force of the elastic element 13 causes the first engaging part 6 to move toward the traction column 2 until the first engaging part 6 is inserted into the first mating groove 7. At this time, although the rope applies a reaction force to the connecting ring 8, the distance between the connecting ring 8 and the hinge column 3 is very close, so it cannot drive the linkage arm 4 to rotate.

[0041] Continue moving the traction frame 1 until the swing arm 9 contacts the crossbeam. At this point, the crossbeam can drive the swing arm 9 and the swing seat 10 to swing upwards until both the swing arm 9 and the swing seat 10 have passed over the crossbeam. The plane containing the side of the swing arm 9 closest to the first fastening part 6 is coplanar with the plane containing the side of the swing seat 10 closest to the first fastening part 6, which facilitates the swing arm 9 and the swing seat 10 passing over the crossbeam. During this process, the force applied by the elastic element 13 to the linkage arm 4 and the swing arm 9 increases, ensuring the stability of the connection between the first fastening part 6 and the traction column 2. After the swing seat 10 passes over the crossbeam, under the action of the elastic element 13 and gravity, the swing seat 10 returns to contact the downstream end of the traction column 2, and at this point, the free end of the rope has passed over the top of the crossbeam.

[0042] In actual operation, the worker only needs to move the traction frame 1 forward. Each process is automatic, requiring no additional operation, thus simplifying the operation and increasing efficiency. Furthermore, the entire traction rope operation only requires moving the traction frame 1, eliminating the need for rope swinging and resulting in better performance. Once the rope has completely passed the crossbeam, it is separated from the connecting ring 8, and then the tarpaulin can be pulled up to cover the entire frame using this rope.

[0043] The mutual contact between the two sides of the linkage arm 4 and the connecting lug 14 improves the relative positional stability between the linkage arm 4 and the hinge post 3. At the same time, the first helix 13a and the second helix 13b (both fixedly connected to the hinge post 3) apply a downward force to the linkage arm 4 through the middle part 13c, and the middle part 13c slides against the linkage arm 4. Therefore, the middle part 13c can continuously apply a downward elastic force to the linkage arm 4 without affecting the normal swing or movement of the linkage arm 4.

[0044] When the worker moves the traction frame 1, the translation frame 15 is in contact with the ground via the translation wheels 16, thus eliminating the need for the worker to continuously hold the traction frame 1, reducing the intensity of manual operation. Secondly, the translation frame 15 has a large area, which effectively ensures the stability of the traction frame 1 and keeps it in a vertical position. Since different crossbeams have different heights, the height of the traction column 2 also needs to be adjusted. In actual adjustment, simply rotate the lifting plate 19 using the operating handle 21. This causes the spiral part 20 (Archimedean spiral shape) to act on the corresponding lifting part 18, raising or lowering the position of the top frame 1b, thereby adjusting the position of the traction column 2 so that it can pass over the corresponding crossbeam.

[0045] It should also be noted that all terms such as "set up" and similar descriptive words in this application (especially the specification) indicate that two structures have or exist a connection relationship. However, the specific means by which the two are connected are not limited in detail, and are usually conventional connection methods. That is, the means should be understood as prior art and do not need to be elaborated. For example, "m is set up with n" only indicates that structure m has structure n, and whether the two are connected by welding, riveting, adhesive, or integral molding is within the scope of protection of this application. Similarly, "x is rotatably set up with y" only indicates that y and x can rotate relative to each other, and whether the two are connected by a bearing, or whether y directly passes through x and is rotatably connected to x, or other feasible methods, are all within the scope of protection of this application.

[0046] The above description is only a description of the preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
