Technical Field
[0001] The utility model relates to the technical field of razor wire nets, in particular to a razor wire net laying and recovery device. Background Art
[0002] Barbed wire is a widely used security product, often used in fences at prisons, border crossings, and high-security locations. Its sharp design provides exceptional protection, but its sharp edge also makes it vulnerable to injury during the deployment and recovery process. Therefore, mechanized auxiliary equipment is crucial to addressing this issue.
[0003] Existing barbed wire mesh laying and recovery devices mostly rely on specific mechanical structures, such as winding, clamping and extrusion types. These devices can reduce the labor intensity of workers and improve work efficiency to a certain extent. However, there are large differences in the diameters of barbed wire meshes of different specifications after being rolled, which puts higher requirements on the adaptability of the retraction and deployment devices. Specifically, traditional retraction and deployment devices are often designed for barbed wire meshes of a certain specification, and their structures, sizes and transmission methods are relatively fixed. When faced with barbed wire mesh rolls of different diameters, these devices may not be able to effectively clamp, resulting in low work efficiency and may even damage the barbed wire mesh or the device itself. Therefore, it is necessary to design a barbed wire mesh laying and recovery device to solve the above problems. Utility Model Content

[0010] Preferably, the first support member is a structural member with a hollow interior.
[0011] Compared with the prior art, the beneficial effects of the present invention are:
[0012] When the utility model needs to clamp knife barb mesh plates of different diameters, the first electric push rod extends out to push the third limit piece to slide along the second limit piece. When the third limit piece slides, the first clamping block is driven to move by the first connecting piece. Since the first connecting piece is composed of two groups of connecting rods, it can ensure that the first clamping block maintains a stable posture when moving. When the first clamping block moves, the slider slides in the slide groove along the slide rod, further improving the stability of the first clamping block when moving. When the first clamping block moves to a suitable position, it adapts to knife barb mesh plates of different diameters.

[0013] The utility model utilizes the extension of the second electric push rod to push the second clamping block, which can fix one end of the knife barbed wire disk without affecting the retraction and extension of the other end of the knife barbed wire disk. The third support member is connected to the engineering vehicle in the prior art by an appropriate method such as bolt connection, welding, etc. The engineering vehicle provides moving power to drive the entire device to move. When it is necessary to clamp the knife barbed wire disk, the knife barbed wire disk is sleeved on the outside of the first clamping block for clamping, and then the clamping assembly is used to fix one end of the knife barbed wire disk, and the other end is connected to a preset bracket such as a fixed bracket on the ground. When the engineering vehicle moves, it drives the first limiting member and the clamped knife barbed wire disk to move, so that the knife barbed wire disk can be deployed or recovered. When it is necessary to adjust the installation height, the extension of the third electric push rod can push the second connecting member to move, driving the first supporting member to slide and rise along the second supporting member. Since the first supporting member is an L-shaped structural member, its lifting will drive the first limiting member and the clamped knife barbed wire disk to lift and fall. In this way, the device can be adjusted according to the actual installation height. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Initial state: The third limiter 3 is located at a certain position of the second limiter 2, the first electric push rod 4 is in the unextended state, the first clamping block 6 is connected to the third limiter 3 through the first connecting member 5 and is in the initial clamping position, the slider 7 is located at the starting position of the slide groove 8, and the slide rod 9 penetrates the slider 7 and is slidably connected to it.
[0022] When it is necessary to clamp the barbed wire mesh plates of different diameters, the first electric push rod 4 extends out to push the third limit member 3 to slide along the second limit member 2. When the third limit member 3 slides, the first clamping block 6 is driven to move by the first connecting member 5. Since the first connecting member 5 is composed of two groups of connecting rods, it can ensure that the first clamping block 6 maintains a stable posture when moving. When the first clamping block 6 moves, the slider 7 slides in the slide groove 8 along the slide rod 9, further improving the stability of the first clamping block 6 when moving. When the first clamping block 6 moves to the appropriate position, it adapts to barbed wire mesh plates of different diameters. One end of the barbed wire mesh plate can be clamped and fixed by the clamping assembly. Compared with the existing technology, it is convenient to adapt to barbed wire mesh plates of different diameters.
[0023] Specifically, the clamping assembly includes a second electric push rod 10 and a second clamping block 11. A group of second electric push rods 10 are installed in the inner cavity of each group of first clamping blocks 6. The output end of the second electric push rod 10 faces one side of the first limit member 1 and is installed with the second clamping block 11.
[0024] By extending the second electric push rod 10, the second clamping block 11 can be pushed to fix one end of the knife-barbed mesh disk without affecting the retraction and extension of the other end of the knife-barbed mesh disk.
[0025] Among them: the first limit member 1 is connected to one end of the first support member 12, the first support member 12 is an L-shaped structural member, and its other end is slidably connected to the second support member 13, the second support member 13 is installed on the upper surface of the third support member 14, and the first support member 12 can be lifted and lowered by a lifting assembly, which includes a second connecting member 15 and a third electric push rod 16. The second connecting member 15 is installed on one side of the first support member 12, and the second connecting member 15 is connected to the output end of the third electric push rod 16. The third electric push rod 16 is installed on one side of the upper surface of the third support member 14, and the first support member 12 is a structural member with a hollow interior.
[0026] The third support member 14 is connected to the engineering vehicle in the prior art by an appropriate method such as bolt connection, welding, etc. The engineering vehicle provides mobile power to drive the entire device to move. When the knife barbed wire mesh disc needs to be clamped, the knife barbed wire mesh disc is placed on the outside of the first clamping block 6 for clamping. Then, one end of the knife barbed wire mesh disc is fixed by the clamping assembly, and the other end is connected to a preset bracket such as a fixed bracket on the ground. When the engineering vehicle moves, it drives the first limiting member 1 and the clamped knife barbed wire mesh disc to move, thereby realizing the deployment or recovery of the knife barbed wire mesh disc.
[0027] When adjustment is required according to the installation height, the third electric push rod 16 is extended to push the second connecting member 15 to move, driving the first support member 12 to slide and rise along the second support member 13. Since the first support member 12 is an L-shaped structural member, its lifting and lowering will drive the first limit member 1 and the clamped barbed wire mesh disk to rise and fall. In this way, the device can be adjusted according to the actual installation height.
[0028] Working principle: The third support member 14 is connected to the engineering vehicle in the prior art by appropriate means such as bolt connection, welding, etc. The engineering vehicle provides mobile power to drive the entire device to move. The extension of the third electric push rod 16 can push the second connecting member 15 to move, driving the first supporting member 12 to slide and rise along the second supporting member 13. Its lifting and lowering will drive the first limiting member 1 and the clamped barbed wire mesh disk to rise and fall. In this way, the device can be adjusted according to the actual installation height. When it is necessary to clamp barbed wire mesh disks of different diameters, the first electric push rod 4 is extended to push the third limiting member 3 to slide along the second limiting member 2. When the third limiting member 3 slides, the first clamping block 6 is driven to move through the first connecting member 5. When the first clamping block 6 moves, the slider 7 slides in the slide groove 8 along the slide rod 9, thereby further improving the stability of the first clamping block 6 when moving. When the first clamping block 6 moves to a suitable position, it can adapt to knife barbed wire discs of different diameters. The second electric push rod 10 is extended to push the second clamping block 11, so as to fix one end of the knife barbed wire disc without affecting the retraction and extension of the other end of the knife barbed wire disc. The other end is connected to a preset bracket such as a fixed bracket on the ground. When the engineering vehicle moves, it drives the first limit member 1 and the clamped knife barbed wire disc to move, thereby realizing the deployment or recovery of the knife barbed wire disc.
