Description

Technical Field

[0001] This utility model relates to the field of demolition equipment technology, and in particular to an integrated hydraulic demolition device for police use. Background Technology

[0002] Demolition techniques are a comprehensive application of cutting, spreading, and jacking techniques by rescue teams based on the actual conditions at the rescue site. Precise and efficient demolition techniques are key to completing rescue missions, while demolition equipment is the foundation and guarantee for the application of demolition techniques.

[0003] Patent No. CN219462360U proposes an integrated hydraulic demolition device for police use. Compared with existing ordinary integrated hydraulic demolition devices for police use, the first hydraulic push rod pushes the propulsion plate, which can push the top plate to both sides through the cooperation of the first and second movable arms, thus completing the expansion support operation. At the same time, when the top plate expands, it will drive the telescopic rod to extend. The telescopic rod and the thrust spring work together to prevent the top plate from moving into the protective cylinder and ensure that the top plate expands stably to the outside.

[0004] However, during the implementation of this device, the shear blade at the front end of the device is always located outside the device during the extension and retraction process. When breaking and cutting fences, multiple people are often required to work together to cut and break them. However, the shear blade at the front end of the device is quite sharp and heavy, so care must be taken to avoid injury to people around during handling and use. Therefore, a police integrated hydraulic demolition device is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide an integrated hydraulic demolition device for police use that can solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a police integrated hydraulic demolition device, comprising a fixed shell, a handle fixedly connected to the surface of the fixed shell, a threaded rod rotatably connected to the inside of the fixed shell, a sliding block slidably connected to the inside of the fixed shell, a breaking structure provided on the surface of the sliding block, the surface of the threaded rod being threadedly connected to the inside of the sliding block, and a protective shell fixedly connected to the surface of the fixed shell.

[0007] Preferably, a motor is fixedly connected to the surface of the fixed shell, the output end of the motor is rotatably connected to the interior of the fixed shell, and the motor is located inside the protective shell.

[0008] Preferably, the inner wall of the fixed shell is provided with a limiting groove, and a limiting rod is fixedly connected to the surface of the sliding block, and the surface of the limiting rod is slidably connected to the inner wall of the limiting groove.

[0009] Preferably, a connecting shell is fixedly connected to the surface of the fixed shell, a limiting plate is slidably connected inside the connecting shell, a sliding rod is fixedly connected to the surface of the sliding block, and a connecting rod is fixedly connected to the surface of the sliding rod.

[0010] Preferably, the surface of the limiting plate is provided with a limiting groove, and the limiting groove is bent, and the inner wall of the limiting groove is slidably connected to the surface of the connecting rod.

[0011] Preferably, the fixed shell is rotatably connected to a rotating shaft, and a cover plate is fixedly connected to the surface of the rotating shaft.

[0012] Preferably, a torsion spring is movably sleeved on the surface of the rotating shaft, and the two ends of the torsion spring are fixedly connected to the fixed shell and the cover plate, respectively.

[0013] Preferably, an impact block is fixedly connected to the surface of the cover plate, and the surface of the impact block is arranged in an arc shape.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) The police integrated hydraulic demolition equipment controls the length of the broken structure outside the fixed shell by starting the motor, and retracts the broken structure. This avoids the front end of the broken structure being outside the fixed shell, which could cause it to touch teammates and people around during transport, thus protecting people and making it easier to transport.

[0016] (2) When the impact block covers the fixed shell, the police integrated hydraulic demolition equipment can swing the fixed shell to make the impact block hit the door panel, thereby further reducing the usage restrictions of the device and increasing the usage effect of the device.

[0017] (3) When the sliding block of the police integrated hydraulic demolition equipment slides, the sliding block drives the sliding rod to move, and the sliding rod drives the connecting rod to move. The moving connecting rod squeezes the inner wall of the limiting groove, so that the limiting plate slides under force and no longer contacts the cover plate. Thus, the limiting plate no longer blocks the rotation of the cover plate, so the sliding block pushes the crushing structure to slide, so that the crushing structure pushes the cover plate, so that the limiting groove flips and no longer covers the fixed shell, so that the crushing structure moves out of the inside of the fixed shell. At the same time, the flipping of the cover plate twists the torsion spring, thus avoiding the crushing structure from contacting external objects during the transportation process.

[0024] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0025] Please see Figure 1-4 This utility model provides a technical solution: a police integrated hydraulic demolition device, including a fixed shell 1, a handle 2 fixedly connected to the surface of the fixed shell 1, a threaded rod 16 rotatably connected to the inside of the fixed shell 1, a sliding block 12 slidably connected to the inside of the fixed shell 1, a breaking structure 11 provided on the surface of the sliding block 12, the surface of the threaded rod 16 being threadedly connected to the inside of the sliding block 12, a motor 6 fixedly connected to the surface of the fixed shell 1, the output end of the motor 6 being rotatably connected to the inside of the fixed shell 1, and a protective shell 3 fixedly connected to the surface of the fixed shell 1, with the motor 6 located inside the protective shell 3.

[0026] When motor 6 starts, the output end of motor 6 drives the threaded rod 16 to rotate. Thus, by limiting the fixed shell 1, the sliding block 12 and the crushing structure 11 will not rotate with the threaded rod 16, but will slide inside the fixed shell 1 as the threaded rod 16 rotates. At the same time, the length of the crushing structure 11 outside the fixed shell 1 is controlled, and the crushing structure 11 is retracted. This avoids the front end of the crushing structure 11 being outside the fixed shell 1, which could cause it to touch teammates and people around during handling, thus protecting people and facilitating its handling.

[0027] The crushing structure 11 cuts and crushes the object by opening and closing the shear blades through a hydraulic telescopic rod. This is an existing known device, so it will not be explained further.

[0028] The inner wall of the fixed shell 1 is provided with a limiting groove 14, and a limiting rod 13 is fixedly connected to the surface of the sliding block 12. The surface of the limiting rod 13 is slidably connected to the inner wall of the limiting groove 14. By setting the limiting rod 13 and the limiting groove 14, the sliding of the breaking structure 11 and the sliding block 12 is restricted, so that they can only slide inside the fixed shell 1.

[0029] A connecting shell 4 is fixedly connected to the surface of the fixed shell 1. A limiting plate is slidably connected inside the connecting shell 4. A sliding rod 15 is fixedly connected to the surface of the sliding block 12. A connecting rod 18 is fixedly connected to the surface of the sliding rod 15. A limiting groove 17 is formed on the surface of the limiting plate 5, and the limiting groove 17 is bent. The inner wall of the limiting groove 17 is slidably connected to the surface of the connecting rod 18. A rotating shaft 9 is rotatably connected inside the fixed shell 1. A cover plate 7 is fixedly connected to the surface of the rotating shaft 9. A torsion spring 10 is movably sleeved on the surface of the rotating shaft 9. The two ends of the torsion spring 10 are fixedly connected to the fixed shell 1 and the cover plate 7, respectively.

[0030] An impact block 8 is fixedly connected to the surface of the cover plate 7. The surface of the impact block 8 is arc-shaped. When the impact block 8 covers the fixed shell 1, the impact block 8 can be made to impact the door panel by swinging the fixed shell 1, thereby further reducing the usage restrictions of the device and increasing the usage effect of the device.

[0031] Working principle: When motor 6 starts, the output end of motor 6 drives the threaded rod 16 to rotate. This, through the constraint of the fixed shell 1, prevents the sliding block 12 and the crushing structure 11 from rotating with the threaded rod 16. Instead, they slide inside the fixed shell 1 as the threaded rod 16 rotates, simultaneously controlling the length of the crushing structure 11 on the outside and retracting it. When the sliding block 12 slides, it drives the sliding rod 15 to move, which in turn drives the connecting rod 18. The moving connecting rod 18 presses against the inner wall of the limiting groove 17, causing the limiting plate 5 to slide under force and no longer contact the cover plate 7. Thus, the limiting plate 5 no longer obstructs the rotation of the cover plate 7, allowing the sliding block 12 to push the crushing structure 11 to slide. This causes the crushing structure 11 to push the cover plate 7, causing the limiting groove 17 to flip and no longer cover the fixed shell 1, allowing the crushing structure 11 to move out of the fixed shell 1. Simultaneously, the flipping of the cover plate 7 twists the torsion spring 10, preventing the crushing structure 11 from contacting external objects during transport.

[0032] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
