Description

Technical Field

[0001] This application relates to the technical field of bridges, and in particular to a bridge demolition device. Background Art

[0002] Bridge demolition refers to the project of demolishing bridges. Bridge demolition methods include blasting demolition, static crushing, and traditional mechanical crushing. In the process of demolishing bridges by traditional mechanical crushing, equipment such as excavators (with breaker hammers), loaders, and cranes are often used.

[0003] A road bridge demolition device mentioned in the existing Chinese patent (authorized announcement number: CN220888348U) includes a demolition device base. The four corners of the lower end of the demolition device base are movably connected with universal wheels. A demolition groove is opened in the middle of the upper end of the demolition device base. One side of the upper end of the demolition device base is fixedly connected with a support frame. For the road bridge demolition device of the present utility model, the air cylinder drives the piston rod to drive the stable plate to move up and down, and the vibration motor drives the connecting rod to drive the oscillating pickaxe to move downward through the demolition groove to demolish the road surface or the bridge deck. Compared with manually holding the device for demolition, the efficiency is greatly improved. At the same time, it can reduce the splashing of crushed stones on the staff, reduce potential safety hazards. The damper and elastic member at the lower end of the connecting block have a certain tension, and the support stable seat supports below the damper and the elastic member to strengthen the supporting force. The anti-slip pad strengthens the friction with the ground at its lower end, making the device more stable during use.

[0004] When the bridge demolition device is in use, it is used for small-scale crushing and impact of the bridge, demolishing the parts that need to be crushed at the bridge connection, reducing the situation of manually holding the device for demolition. However, during the crushing and demolition, it is easy for debris and dust to fly around, which is easily inhaled by the surrounding staff, and thus it is easy to affect the surrounding staff and the environment, making it inconvenient to use the bridge demolition device. Summary of the Utility Model

[0005] The purpose of this application is to solve the problem that during the crushing and demolition, it is easy for debris and dust to fly around, which is easily inhaled by the surrounding staff, and thus it is easy to affect the surrounding staff and the environment, making it inconvenient to use the bridge demolition device. This application provides a bridge demolition device.

[0006] This application specifically adopts the following technical solutions to achieve the above purpose:

[0032] The following further describes this application in detail with reference to the Figures 1-4 accompanying drawings.

[0033] An embodiment of this application discloses a bridge demolition device.

[0034] Referring to Figure 1 and Figure 2 , a bridge demolition device includes a frame 1. Two symmetrical support plates 2 are fixedly installed at the lower end inside the frame 1. Two symmetrical universal wheels 3 are installed at the lower ends of the two support plates 2. Two symmetrical handles 4 are fixedly installed on one side of the frame 1. A hydraulic telescopic rod 5 is arranged inside the frame 1. The telescopic end of the hydraulic telescopic rod 5 is fixedly connected to a fixed plate 6. One end of the fixed plate 6 away from the hydraulic telescopic rod 5 is fixedly connected to a limiting telescopic rod 8. A crushing device 7 is fixedly installed at the lower end of the fixed plate 6. A cleaning box 9 is fixedly installed on one side of the frame 1. A cleaning mechanism is arranged between the frame 1 and the support plate 2.

[0035] When the bridge demolition device is in use, the staff push the handle 4 to drive the frame 1 to move, so that the universal wheels 3 rotate, facilitating the transportation of the frame 1 to a suitable position. Then, the universal wheels 3 are self-locked, and the hydraulic telescopic rod 5 is started to extend and retract, driving the fixed plate 6 to move, so that the fixed plate 6 drives the extension and retraction of the limiting telescopic rod 8 to limit the fixed plate 6, enabling the crushing device 7 to crush the position to be crushed. The frame 1 blocks the broken pieces splashing during crushing. Through the cleaning mechanism, the debris and dust generated during crushing are cleaned and collected, reducing the inhalation of the staff and the impact on the surrounding staff, and facilitating the use.

[0036] Referring to Figure 2 and Figure 3, The cleaning mechanism includes a horn-shaped pipe 12 fixed to the inner wall of the frame body 1. One end of the horn-shaped pipe 12 extends out of the frame body 1 and is fixedly connected to the cleaning box 9. A cover plate 10 is fixed to the end of the cleaning box 9 away from the horn-shaped pipe 12, and an air outlet pipe 11 is fixed to the cover plate 10. A cleaning component is arranged in the cleaning box 9. The cleaning component includes a motor 13 fixed in the cleaning box 9. The output end of the motor 13 is fixedly connected with fan blades 14 and is arranged in an array. The fan blades 14 correspond to the horn-shaped pipe 12. A collecting piece is arranged between the motor 13 and the horn-shaped pipe 12. The collecting piece includes a filter screen 15 arranged in the cleaning box 9. The filter screen 15 is located on the side of the fan blades 14 away from the motor 13. A collecting box 16 is arranged on the side of the filter screen 15, and the filter screen 15 corresponds to the collecting box 16.

[0037] When the bridge demolition equipment is in use, start the motor 13. The motor 13 drives the fan blades 14 to rotate to generate suction. The suction draws air into the cleaning box 9 from the horn mouth, inhaling debris and dust. The horn mouth expands the suction area. The entering debris and dust are blocked and filtered by the filter screen 15, and the air is discharged through the air outlet pipe 11. The debris and dust blocked by the filter screen 15 enter the collecting box 16, facilitating the collection of debris and dust. Through the cleaning mechanism, the debris and dust generated during crushing are cleaned and collected, reducing the inhalation of the staff and the impact on the surrounding staff, and facilitating use.

[0038] Refer to Figures 2-4 , One end of the filter screen 15 extends out of the cleaning box 9 and is fixed by bolts. The collecting box 16 extends out of the cleaning box 9, and the collecting box 16 is fixed to the cleaning box 9 by bolts. An electric motor 17 is fixed to the side of the frame body 1. The output end of the electric motor 17 extends into the frame body 1 and is fixedly connected with a screw rod 18. A moving plate 19 is threadedly connected to the screw rod 18. The hydraulic telescopic rod 5 is fixedly connected to the moving plate 19, and the limiting telescopic rod 8 is fixedly connected to the moving plate 19. A limiting column 20 is fixed to the inner wall of the frame body 1. The limiting column 20 slidably penetrates through the moving plate 19. The limiting column 20 is located on the side of the hydraulic telescopic rod 5, and a limiting block is fixed to one end of the limiting column 20. An observation window 21 is fixed to the side of the frame body 1. The observation window 21 is made of tempered glass.

[0039] When the bridge demolition equipment is in use, when cleaning and replacement are required, loosen the bolts on the cleaning box 9 to release the restriction on the filter screen 15, pull out the filter screen 15 from the cleaning box 9, then loosen the bolts on the collecting box 16 and remove the collecting box 16. After cleaning and replacement, reset. Start the electric motor 17. The rotation of the electric motor 17 causes the screw rod 18 to rotate, making the moving plate 19 move. The moving plate 19 slides on the limiting column 20 to restrict the moving plate 19, facilitating the adjustment of the position of the crushing device 7 and enabling precise crushing at a specified position. The limiting block restricts the moving plate 19, and through the observation window 21 made of tempered glass, it is convenient to perform crushing at a specified position and observe.

[0040] The implementation principle of a bridge demolition device in this embodiment is as follows: When using the bridge demolition device, the staff push the handle 4 to drive the frame 1 to move, causing the universal wheels 3 to rotate, which facilitates transporting the frame 1 to a suitable position. Then, the universal wheels 3 are self-locked. Next, the hydraulic telescopic rod 5 is started to expand and contract, driving the fixed plate 6 to move. The fixed plate 6 drives the expansion and contraction of the limiting telescopic rod 8 to restrict the fixed plate 6, enabling the crushing device 7 to crush the position that needs to be crushed, and the frame 1 blocks the fragmented pieces splashing during crushing.

[0041] When using the bridge demolition device, start the motor 13. The motor 13 drives the fan blade 14 to rotate to generate suction. The suction sucks air from the bell mouth into the cleaning box 9 to suck in debris and dust. The bell mouth expands the suction area. The entering debris and dust are blocked and filtered by the filter screen 15, and the air is discharged through the air outlet pipe 11. The debris and dust blocked by the filter screen 15 enter the collection box 16, which facilitates the collection of debris and dust.

[0042] When using the bridge demolition device, start the motor 17. The rotation of the motor 17 causes the screw 18 to rotate, which makes the moving plate 19 move. The moving plate 19 slides on the limiting column 20 to restrict the moving plate 19, facilitating the adjustment of the position of the crushing device 7 and enabling precise crushing of the designated position. The limiting block restricts the moving plate 19. Through the observation window 21 made of tempered glass, it is convenient to observe the crushing of the designated position. When cleaning and replacement are required, loosen the bolts on the cleaning box 9 to release the restriction on the filter screen 15, pull out the filter screen 15 from the cleaning box 9, then loosen the bolts on the collection box 16 and remove the collection box 16. After cleaning and replacement, reset.
