DETAILED DESCRIPTION

[0019] The preferred embodiments of the present application will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to explain and illustrate the present application, and are not used to limit the present application.

[0020] The present application discloses a kind of outer tensioning gabion net lead-out equipment, such as Figures 1 to 14As shown, the gabion mesh 700 includes a mesh guide mechanism 100 and an external roller assembly, which are arranged at intervals along the conveying direction of the gabion mesh 700. The external roller assembly includes a plurality of external rollers 200, which are rotatably connected to the body 800 at intervals along the conveying direction of the gabion mesh 700. These external rollers 200 are all connected to the drive mechanism 500, and an external drive assembly 300 is provided at each end of each external roller 200. The working principle and advantages of the present invention are as follows: the present invention continuously and stably supplies the gabion mesh 700 to the external roller group through the guide mechanism 100; in the process of the gabion mesh 700 passing through the external roller group, the multiple external rollers 200 in the external roller group are driven by the driving mechanism 500 to rotate synchronously and transport the gabion mesh 700. At the same time, these external rollers 200 support the gabion mesh 700 outwards through the external drive assembly 300. Since the mesh of the gabion mesh 700 is formed by interlacing hard metal wires, the gabion mesh 700 is connected to the external roller group by the external roller group. The mesh of the gabion mesh 700 is formed by forking and weaving, and a metal wire braiding knot is formed. In this way, the mesh of the gabion mesh 700 has four metal wire braiding knots. In the process of stretching the gabion mesh 700 outward, the metal wire braiding knots will gradually tighten, that is, the knots are stretched and gradually shortened, and the circumference of the mesh gradually increases, so that the mesh of the gabion mesh 700 gradually becomes larger; and these external expansion rollers 200 perform a progressive external expansion operation on the gabion mesh 700, thereby ensuring the continuity of the entire operation, thereby achieving the purpose of improving the efficiency of the external expansion operation. In summary, the present invention can effectively reduce the investment cost of the equipment, and can perform continuous external expansion operations on the gabion mesh 700 as needed, so that the mesh of the gabion mesh 700 is deformed, thereby obtaining the gabion mesh 700 with the desired mesh shape, reducing the intensity of the operation and improving the efficiency of production.

[0021] As a preferred embodiment of the present invention, Figures 2 to 4 As shown, the mesh guide mechanism 100 comprises an adapter 101, an inlet roller 102, an outlet roller 103, a sliding base 104, and two tensioning rollers 105. The inlet roller 102 and outlet roller 103 are mounted on the adapter 101 at intervals along the conveying direction of the gabion mesh 700. The sliding base 104 is slidably connected to the lower end of the adapter 101. Two tensioning rollers 105 are mounted on the sliding base 104. These two tensioning rollers 105 are located below and between the inlet roller 102 and outlet roller 103. The tensioning roller 105 closer to the outlet roller 103 is lower than the other tensioning roller 105. The lower tensioning roller 105 is designated as tensioning roller 105A, while the other tensioning roller 105 is designated as tensioning roller 105B. The sliding base 104 is connected to a longitudinal drive 106, which is typically a pneumatic cylinder or a hydraulic cylinder. The working principle and advantages of this embodiment are: This embodiment realizes the input and output of the gabion mesh 700 through the introduction roller 102 and the output roller 103. Figure 3The illustrated mode is through the import roller 102, two tension rollers 105, the export roller 103, and then supplied to the outer tension roller group.In this process, the tension roller 105A is responsible for tensioning the gabion 700 to ensure that the gabion 700 is stably conveyed to the outer tension roller group in a state of tension.When the gabion 700 is slack, the longitudinal drive 106 is controlled to act so that the sliding seat 104 and the two tension rollers 105 move longitudinally, so that the distance between the tension roller 105A and the export roller 103 becomes larger, and the part of the gabion 700 between the tension roller 105A and the export roller 103 is tensioned, so that the gabion 700 entering the outer tension roller group remains in a state of tension.When the gabion 700 is too tight, the longitudinal drive 106 is controlled to act in the opposite direction, so that the part of the gabion 700 entering the outer tension roller group becomes loose.Furthermore, due to the different heights of the two tension rollers 105, whether the part of the gabion 700 entering the outer tension roller group is loosened or tightened, the degree of slackness of the part of the gabion 700 between the tension roller 105B and the import roller 102 changes little, thereby ensuring that the gabion 700 is stably conveyed into the guide mechanism 100.

[0022] As a preferred embodiment of the present application, as shown in Figure 6 、 Figure 8 、 Figure 9 、 Figure 10 The outer tension roller 200 includes a conveying roller 201 and two movable rollers 204, the axes of the three coincide, the two movable rollers 204 are movably connected with the two ends of the conveying roller 201, and a plurality of conveying toothed discs 203 are fixedly sleeved on the conveying roller 201, the conveying toothed discs 203 are spaced along the axis of the conveying roller 201, a plurality of tension toothed discs 206 are fixedly sleeved on each movable roller 204, the tension toothed discs 206 are spaced along the axis of the movable roller 204, the distance between the tension toothed discs 206 is smaller than the distance between the conveying toothed discs 203, and each movable roller 204 is connected with a corresponding outer tension driving assembly 300.The working principle and advantages of the present embodiment are that: after the gabion 700 enters the outer tension roller group, the conveying roller 201 and the conveying toothed discs 203 thereon convey it, specifically, in the process of rotation of the conveying roller 201, the teeth of the plurality of conveying toothed discs 203 extend into the mesh holes at the corresponding positions of the gabion 700, thereby pushing the gabion 700 to convey forward.At the same time, the movable roller 204 rotates with the conveying roller 201, the teeth of the plurality of tension toothed discs 206 on the movable roller 204 extend into the mesh holes at the corresponding side edges of the gabion 700, at this time, the outer tension driving assembly 300 is controlled to pull the movable roller 204 outward, so that the tension toothed discs 206 convey the side edges of the gabion 700 while tensioning the side edges of the gabion 700 outward, thereby gradually deforming the mesh holes of the gabion 700.

[0023] As a preferred embodiment of the present application, as shown in Figure 9 The specific connection mode between the conveying roller 201 and the movable roller 204 is that a plurality of first insertion strips 202 are arranged on the end of the conveying roller 201 close to the movable roller 204, the first insertion strips 202 are evenly arranged along the circumference of the conveying roller 201, and a first insertion slot is formed between two adjacent first insertion strips 202. In this embodiment, a plurality of second insertion strips 205 are arranged on the end of the movable roller 204 close to the conveying roller 201, the second insertion strips 205 are evenly arranged along the circumference of the movable roller 204, a second insertion slot is formed between two adjacent second insertion strips 205, the first insertion strip 202 is movably inserted into the corresponding second insertion slot, and the second insertion strip 205 is movably inserted into the corresponding first insertion slot. Under the tension of the outer stretching driving assembly 300, the movable roller 204 moves away from the conveying roller 201, at this time, the depth of the second insertion strip 205 inserted into the first insertion slot is adjusted, and at the same time, the synchronous rotation of the conveying roller 201 and the movable roller 204 is not affected.

In this embodiment, the stiffness of the first columnar spring 209 in the plurality of outer stretching rollers 200 in the outer stretching roller group decreases along the conveying direction of the gabion net 700, that is, the stiffness of the first columnar spring 209 located at the inlet end of the outer stretching roller group is greater than the stiffness of the first columnar spring 209 located at the outlet end of the outer stretching roller group. In this way, when all the outer stretching driving assemblies 300 are driven to act, the pulling displacement of the outer stretching driving assemblies 300 increases along the conveying direction of the outer stretching roller group, so that the stretching amount of the first columnar spring 209 also increases, thereby realizing progressive tensioning of the gabion net 700, so that the mesh holes on the gabion net 700 are gradually stretched and deformed, thereby ensuring the continuity of the entire stretching process.

The piston cylinder 301 has a driving cavity 302, and the cross section of the driving cavity 302 is also a regular polygon.

In this embodiment, the piston cylinder 301 is driven to rotate by the driving mechanism 500, and the piston cylinder 301 drives the outer stretching roller 200 to rotate through the stretching rod 306.

In this way, under the driving of the high-pressure gas with the predetermined pressure, the displacement of the outer stretching driving assembly 300 outwardly stretching increases along the conveying direction of the stone cage net 700, and the stretching amount of the second columnar spring 303 also increases, so that the stretching degree of the stone cage net 700 by the outer stretching rollers 200 is continuous and progressive.
