Description

Technical Field

[0001] The utility model relates to the technical field of special-shaped winding machines for webbing, in particular to a special-shaped winding machine for webbing. Background Art

[0002] Traditional steel chains are heavy, weighing 3 kilograms per meter. They are troublesome for workers to operate, with low efficiency, and require multiple workers to operate under complex working conditions. The chains are prone to rusting and breaking, and their service life is 3 - 5 years. Moreover, if there is damage to the steel chain, it cannot be distinguished by the naked eye. After using it for a period of time, it must be pulled back to the manufacturer for inspection to identify which section of the chain is damaged, and the tensile force cannot reach the original load. Content of the Utility Model

[0003] The purpose of the utility model is to provide a special-shaped winding machine for webbing to solve at least one of the above problems existing in the prior art.

[0004] To achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A special-shaped winding machine for webbing, comprising a workbench and four actuating rods. The four actuating rods are spaced apart along a straight line. An avoidance hole is provided on the workbench. Below the workbench, there are cylinders respectively controlling the four actuating rods to reciprocate back and forth along the avoidance hole. A manual valve for respectively controlling the corresponding cylinders is provided on the workbench. The two middle actuating rods are used to position and press the inner side of the special-shaped winding coil, and the two outer actuating rods are used to press the outer side of the special-shaped winding coil.

[0006] It should be noted that for the special-shaped winding loops, one loop is wound from the inside and the next loop is wound from the outside, with the inner and outer layers pressing against each other layer by layer. The function of the special-shaped winding chain formed by this winding method is to bear the maximum load during use. With this technical solution, such special-shaped winding loops can be wound, and on the basis of the special-shaped winding loops, a special-shaped winding chain can be continuously wound. The special-shaped winding chain is formed by sequentially sleeving a number of special-shaped winding loops. During the winding process of each loop of the next special-shaped winding loop, the webbing needs to pass through another special-shaped winding chain to achieve the connection of adjacent special-shaped winding loops, and finally a special-shaped winding chain is formed. Specifically, during winding, the webbing is initially positioned and wound around the upper ends of the two middle actuator rods. At this time, the two middle actuator rods can play a role in initial positioning, defining the size of the special-shaped winding loop formed by the webbing winding, that is, the inner circle length of the special-shaped winding loop is determined by the distance between the two middle actuator rods; during the winding of the outer layer, the outer actuator rod moves away from the webbing, providing space for the winding of the outer layer of the webbing, and then the outer actuator rod is moved towards the webbing wound in the outer layer. The outer actuator rod can press the webbing from the outside of the special-shaped winding loop; during the winding of the inner layer, by moving the corresponding middle actuator rod, the actuator rod is kept at a certain distance from the special-shaped winding loop, providing space for the winding of the inner layer of the special-shaped winding loop. After the inner circle winding is in place, the two middle actuator rods can also press the special-shaped winding loop from the inside. It should be noted that during actual operation, the worker will twist the webbing by 180° after each loop of the webbing is wound. This way of alternating inner and outer layer winding can achieve the special-shaped winding loop with inner and outer layers wound and pressed layer by layer. When connecting adjacent special-shaped winding loops, it is only necessary to pass through the special-shaped winding loop to be connected during each loop winding. By repeating this way in sequence, finally a special-shaped winding chain with strong load-bearing capacity can be wound. During the winding process, by operating the corresponding manual valve by the worker, the forward and backward movement of the corresponding actuator rod can be controlled as needed, that is, the actuator rod moves away from or towards the special-shaped winding loop, thus providing convenience for the worker to alternately wind the inner and outer circles of the webbing. Combining with the specific winding method of the webbing, the two outer actuator rods in this technical solution are used to press the rope from the outside during the winding process, which can keep each loop of winding uniform, with one loop tightly attached to another without loosening; the two actuator rods located in the middle first play a positioning role to ensure that each ring of the special-shaped winding loop wound is of the same size, and can also press the special-shaped winding loop from the inside during the winding process to ensure that each loop is easily wound without loosening. The function of the actuator rod is to position and press the webbing during the webbing winding process, enabling the worker to effectively control the size during the operation, and ensuring that each produced ring is of the same size. Each loop of winding is uniform and smooth, ensuring that each loop is evenly stressed during use, achieving the maximum bearing capacity, and having a beautiful appearance.In summary, the present technical solution provides a device capable of winding special-shaped winding rings with alternating inner and outer layers. It is convenient to operate and can ensure the winding quality of the special-shaped winding rings, solving the problems of the existing steel chains being heavy, cumbersome to operate, affecting work efficiency, prone to rust and breakage, and the damage being indistinguishable by the naked eye.

[0007] Further, the lower end of the actuating rod is simultaneously connected to the piston rods of two cylinders. Two cylinders are selected because when a single cylinder is stressed, the cylinder diameter is prone to uneven expansion and contraction due to uneven force.

[0008] Further, the stroke of the actuating rod is 25 mm, which can easily press down or release the webbing.

[0009] Further, in order to make the arrangement of the cylinders more compact and facilitate the driving of the actuating rod, the two middle actuating rods are the second actuating rod and the third actuating rod, the actuating rod close to the outside of the second actuating rod is the first actuating rod, and the actuating rod close to the outside of the third actuating rod is the fourth actuating rod. Long brackets and short brackets are provided at the lower end of the workbench. The long bracket is located between the two short brackets. Four cylinders are longitudinally arranged on the long bracket. The lower end of the second actuating rod is connected to the piston rods of two cylinders on the long bracket. The lower end of the third actuating rod is connected to the piston rods of the other two cylinders on the long bracket. Two cylinders are respectively provided on the two short brackets. The lower ends of the first actuating rod and the fourth actuating rod are respectively connected to the piston rods of the two cylinders provided on the corresponding short brackets.

[0010] Further, in order to ensure the stable movement of the two middle actuating rods with a relatively short distance between them, the four cylinders on the long bracket are the first cylinder, the second cylinder, the third cylinder, and the fourth cylinder from top to bottom. The lower end of the second actuating rod is connected to the piston rods of the first cylinder and the third cylinder on the long bracket. The lower end of the third actuating rod is connected to the piston rods of the second cylinder and the fourth cylinder on the long bracket.

[0011] Further, in order to limit the moving distance of the actuating rod, a U-shaped limit frame is provided at the end of the cylinder, and the lower end of the actuating rod is located within the U-shaped limit frame.

[0012] Further, in order to facilitate the staff to manually operate the manual valve and wind the webbing, the manual valve is a two-position five-way manual valve. Four two-position five-way manual valves are horizontally spaced on the workbench. Four actuating rods are longitudinally spaced on the workbench. The four two-position five-way manual valves are located on one side of the four actuating rods. The four two-position five-way manual valves are respectively used to control the movement of the four actuating rods.

[0013] Further, to facilitate the air circuit connection between the cylinder and the manual valve, the manual valve is a two-position five-way manual valve. Each of the four two-position five-way manual valves is connected with an input pipe and two output pipes. The input pipe is connected to the air source, and the two output pipes are respectively connected to both ends of the corresponding cylinder.

[0014] Further, to facilitate the connection between the input pipe and the manual valve, the four two-position five-way manual valves are, from right to left, the first valve, the second valve, the third valve, and the fourth valve. The input pipes of the first valve and the second valve are connected to the first pipe through the first pneumatic three-way joint. The input pipes of the third valve and the fourth valve are connected to the second pipe through the second pneumatic three-way joint. The first pipe and the second pipe are connected to the third pipe through the third pneumatic three-way joint, and the third pipe is connected to the air source.

[0015] Further, to facilitate providing a matching sequence for workers to operate the manual valve to control the corresponding actuator rod conveniently, there are four manual valves. The four manual valves are, from right to left, the first valve, the second valve, the third valve, and the fourth valve. The first valve controls the first actuator rod, the second valve controls the second actuator rod, the third valve controls the third actuator rod, and the fourth valve controls the fourth actuator rod.

[0016] The beneficial effects of the present utility model are as follows: It should be noted that for the special-shaped winding loops, one loop is wound from the inside and the next loop is wound from the outside, with the inner and outer layers pressing against each other layer by layer. The special-shaped winding chain formed by this winding method can bear the maximum load during use. With this technical solution, such special-shaped winding loops can be wound, and based on the special-shaped winding loops, a special-shaped winding chain can be continuously wound. The special-shaped winding chain is formed by sequentially sleeving a number of special-shaped winding loops. During the winding process of each loop of the next special-shaped winding loop, the webbing needs to pass through another special-shaped winding chain to achieve the connection of adjacent special-shaped winding loops, and finally a special-shaped winding chain is formed. Specifically, during winding, the webbing is initially positioned and wound around the upper ends of the two middle actuator rods. At this time, the two middle actuator rods can play a role in initial positioning, limiting the size of the webbing wound into a special-shaped winding loop, that is, the inner circle length of the special-shaped winding loop is determined by the distance between the two middle actuator rods; during the winding of the outer layer, the outer actuator rod moves away from the webbing, providing space for the winding of the outer layer of the webbing. Then, the outer actuator rod is moved towards the webbing wound in the outer layer, and the outer actuator rod can press the webbing from the outside of the special-shaped winding loop; during the winding of the inner layer, by moving the corresponding middle actuator rod, the actuator rod is kept at a certain distance from the special-shaped winding loop, providing space for the winding of the inner layer of the special-shaped winding loop. After the inner circle winding is in place, the two middle actuator rods can also press the special-shaped winding loop from the inside. It should be noted that during actual operation, the worker will twist the webbing by 180° after each loop of the webbing is wound. This way of alternating inner and outer layer winding can achieve a special-shaped winding loop with inner and outer layers wound layer by layer and pressed layer by layer. When connecting adjacent special-shaped winding loops, it is only necessary to pass through the special-shaped winding loop to be connected during each loop of winding. By repeating this way successively, a special-shaped winding chain with strong bearing capacity can finally be wound. During the winding process, by the worker operating the corresponding manual valve, the forward and backward movement of the corresponding actuator rod can be controlled as needed, that is, the actuator rod moves away from or towards the special-shaped winding loop, thus providing convenience for the worker to alternately wind the inner and outer circles of the webbing. Combining with the specific winding method of the webbing, the two outer actuator rods in this technical solution are used to press the rope from the outside during the winding process, which can keep each loop of winding uniform, with one loop tightly attached to another without loosening; the two actuator rods located in the middle first play a positioning role, ensuring that each ring of the special-shaped winding loop wound is of the same size, and can also press the special-shaped winding loop from the inside during the winding process, ensuring that each loop is easily wound without loosening. The role of the actuator rod is to position and press the webbing during the webbing winding process, enabling the worker to effectively control the size during the operation, and making each ring produced of the same size. Each loop of winding is uniform and smooth, ensuring that each loop is evenly stressed during use, achieving the maximum bearing capacity, and having a beautiful appearance.In summary, the present technical solution provides a device capable of winding a special-shaped winding coil with alternating inner and outer layers. It is convenient to operate and can ensure the winding quality of the special-shaped winding coil, solving the problems of the existing steel chain being heavy, cumbersome to operate, affecting work efficiency, being prone to rust and breakage, and the damage being indistinguishable by the naked eye.

Detailed implementation mode

[0029] In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the present invention will be briefly introduced below in combination with the accompanying drawings and the description of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other accompanying drawings can also be obtained based on these drawings. It should be noted here that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation to the present invention.

[0030] Embodiment 1:

[0031] As Figures 1-11 shown, this embodiment provides a special-shaped winding machine for webbing, including a workbench 1 and four actuating rods 2. The four actuating rods 2 are spaced apart along a straight line. An avoidance hole 3 is provided on the workbench 1. Below the workbench 1, there are cylinders 4 respectively controlling the reciprocating movement of the four actuating rods 2 along the avoidance hole 3. A manual valve 5 for respectively controlling the corresponding cylinders 4 is provided on the workbench 1. The two actuating rods 2 in the middle are used to position and press the inner side of the special-shaped winding ring 6, and the two actuating rods 2 on the outside are used to press the outside of the special-shaped winding ring 6.

[0032] It should be noted that the special-shaped winding ring 6 is to be wound one circle from the inside and one circle from the outside, with the inside and outside layers pressing against each other. The function of the special-shaped winding chain formed by this winding method is to bear the maximum load during use. With this technical solution, such a special-shaped winding ring 6 can be wound, and on the basis of the special-shaped winding ring 6, a special-shaped winding chain can be continuously wound. The special-shaped winding chain is formed by sequentially sleeving a number of special-shaped winding rings 6. During the winding process of each circle of the next special-shaped winding ring 6, the webbing needs to pass through another special-shaped winding chain to realize the connection of adjacent special-shaped winding rings 6, and finally a special-shaped winding chain is formed. During specific winding, the webbing 6.1 is initially positioned and wound around the upper ends of the two actuating rods 2 in the middle (as Figure 5 shown). At this time, the two actuating rods 2 in the middle can play a role in initial positioning, limiting the size of the webbing 6.1 wound into the special-shaped winding ring 6, that is, the inner circle length of the special-shaped winding ring 6 is determined by the distance between the two actuating rods 2 in the middle; as Figure 8 , Figure 9 shown, during the winding of the outer layer, the outer actuating rod 2 moves away from the webbing 6.1, providing space for the winding of the outer layer of the webbing 6.1. Then, the outer actuating rod 2 is moved towards the webbing 6.1 wound in the outer layer. The outer actuating rod 2 can press the webbing 6.1 from the outside of the special-shaped winding ring 6; as Figures 5-7As shown, during the process of winding the inner layer, the corresponding actuating rod 2 located in the middle can be moved, such as Figure 7 As shown, when the actuating rod 2 is at a certain distance from the special-shaped winding coil 6, space is provided for the inner-layer winding of the special-shaped winding coil 6. After the inner-layer winding is in place, the two actuating rods 2 located in the middle can also press the special-shaped winding coil 6 from the inside. It should be noted that during actual operation, the staff will twist the webbing 6.1 by 180° after each turn of the webbing 6.1 is wound. The twisting method for the inner-layer winding is as shown in Figures 5-6 As shown, and the twisting method for the outer-layer winding is as shown in Figure 8 As shown. This way of alternating inner and outer layer winding can achieve the special-shaped winding coil 6 with layers of winding and layers of pressing. When connecting adjacent special-shaped winding coils 6, it is only necessary to pass through the special-shaped winding coil 6 to be connected during each turn of winding. By adopting the repeated method in sequence, a special-shaped winding chain with strong bearing capacity can finally be wound. During the winding process, by operating the corresponding manual valve 5 by the staff, the forward and backward movement of the corresponding actuating rod 2 can be controlled as needed, that is, the actuating rod 2 moves in the direction away from or close to the special-shaped winding coil 6, thus providing convenience for the staff to alternately wind the inner and outer circles of the webbing 6.1. Combining with the specific winding method of the webbing 6.1, the two outer actuating rods 2 in this technical solution are used to press the rope from the outside during the winding process, which can keep each turn of winding uniform, with one turn tightly attached to another without loosening; the two actuating rods 2 located in the middle first play a positioning role to ensure that each ring of the special-shaped winding coil 6 wound is of the same size, and can also press the special-shaped winding coil 6 from the inside during the winding process to ensure that each turn is easily wound without loosening. The function of the actuating rod 2 is to position and press the webbing 6.1 during the winding process of the webbing 6.1, so that the worker can effectively control the size during the operation process, and each ring produced is of the same size. Each turn of winding is uniform and smooth, ensuring that each ring is evenly stressed during use, achieving the maximum bearing capacity, and having a beautiful appearance. In summary, this technical solution provides a device capable of winding the special-shaped winding coil 6 with alternating inner and outer layer winding, which is convenient to operate and can ensure the winding quality of the special-shaped winding coil 6, solving the problems of the existing steel chain being heavy, cumbersome to operate, affecting work efficiency, being prone to rust and breakage, and the damage being indistinguishable by the naked eye.
