Description

Technical Field

[0001] This utility model relates to the field of reinforced concrete frame structure demolition technology, specifically a reinforced concrete frame structure demolition device. Background Technology

[0002] A reinforced concrete frame structure is a spatial skeleton structure formed by reinforced concrete beams, columns, and floor slabs as the main load-bearing components, which are rigidly connected at joints. It can withstand the vertical loads (such as self-weight and live loads) and horizontal loads (such as earthquake and wind loads) of the building.

[0003] For example, a demolition device for reinforced concrete, with announcement number "CN219974504U," facilitates the cutting of concrete during tunnel secondary lining construction using a cutting disc in the cutting component. When cutting exposed reinforcing bars, a telescopic component retracts the cutting component, causing the shearing component to protrude via a straight toothed plate and drive gear. The shearing blades of the shearing component then cut the reinforcing bars within the concrete, thus providing a convenient method for shearing reinforcing bars. However, this device, which adjusts the position of the shearing blades on both sides using a bidirectional adjusting screw, can cause deformation when the diameter of the reinforcing bar is large. This reduces the device's applicability. Furthermore, the device relies on a limiting block and limiting groove for guidance during adjustment of the shearing and cutting components. Dust or concrete residue can easily enter the limiting groove, leading to jamming during adjustment. Utility Model Content

[0004] The purpose of this invention is to solve the problem that when adjusting the position of the shearing blades on both sides using a bidirectional adjusting screw, the reaction force generated when the diameter of the reinforcing bar is large is transmitted to the screw through the slider, which can easily cause the screw to deform and reduce the applicability of the equipment. At the same time, when adjusting the shearing and cutting components, the device uses the cooperation of the limiting block and the limiting groove for guidance, and dust or concrete residue can easily enter the limiting groove, causing jamming during adjustment. Therefore, this invention proposes a demolition device for reinforced concrete frame structures.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a demolition device for reinforced concrete frame structure, including a mounting plate and electric telescopic rods. Multiple electric telescopic rods are fixedly connected to the bottom of the mounting plate. The output ends of the electric telescopic rods are respectively fixedly connected to a housing and a box. A guide structure is provided on the top of the housing and the box. A shearing structure is provided inside the box. An inspection door is installed on the right side of the box. The left side of the housing is threadedly connected to a servo motor by bolts.

[0007] This feature: The access door facilitates the maintenance of components inside the enclosure 8.

[0008] Preferably, a cutting disc is fixedly connected to the end of the output shaft of the servo motor, and both sides of the cutting disc are rotatably connected to the housing through bearings.

[0009] This setting: The set cutting disc facilitates the cutting of concrete.

[0010] Preferably, the guide structure includes a sleeve, and a sealing ring is installed on the lower part of the inner wall of each of the sleeves. The sealing ring and the inner wall of the sleeve are slidably connected to the slide rod, and the lower part of the slide rod is fixedly connected to the housing and the box body respectively.

[0011] This feature: The sealing ring is made of hydrogenated nitrile rubber, which has excellent resistance to corrosion, tearing, compression, and deformation, as well as good resistance to sunlight and ozone.

[0012] Preferably, the upper part of each sleeve is fixedly connected to the mounting plate.

[0013] This feature: The combination of the sliding rod and the sleeve can serve as a guide.

[0014] Preferably, the shearing structure includes a hydraulic cylinder, a slider is fixedly connected to the output end of the hydraulic cylinder, a cylinder is fixedly connected to the outer wall of the slider, the outer wall of the cylinder is slidably connected to a sliding groove, the sliding groove is machined on the inner wall of the first shearing blade, and the upper part of the first shearing blade is movably connected to the housing via a pin.

[0015] This feature allows the cylinder to slide within the groove via a hydraulic cylinder, which in turn moves the first shearing blade.

[0016] Preferably, a second shearing blade is fixedly connected to the inner wall of the box.

[0017] This feature allows for the cutting of reinforced concrete frame structures through the cooperation of the second and first shear blades.

[0018] The present invention proposes a demolition device for reinforced concrete frame structures, which has the following advantages: through the cooperation of the box and the shearing structure, the hydraulic cylinder output end moves to drive the slider to move, thereby driving the cylinder to slide along the inner wall of the groove, which in turn drives the first shearing blade to swing, so as to achieve greater shearing force of the first and second shearing blades, which can easily cut large-diameter reinforced concrete frame structures, and to a certain extent, can improve the applicability of the equipment.

[0019] With the cooperation of the mounting plate and guide structure, the output end of the electric telescopic rod moves, driving the housing to move. At the same time, it drives the slide rod to slide along the sealing ring and the inner wall of the sleeve. The sealing ring can play a sealing role, reducing the entry of dust or concrete residue into the sleeve, which can easily cause jamming during adjustment. Attached Figure Description

[0026] The present invention will be further described below with reference to the accompanying drawings:

[0027] See attached document Figure 1-5 In this embodiment, a demolition device for a reinforced concrete frame structure includes a mounting plate 1 and an electric telescopic rod 2. Multiple electric telescopic rods 2 are fixedly connected to the bottom of the mounting plate 1. The output ends of the electric telescopic rods 2 are respectively fixedly connected to a housing 9 and a box 8. A guide structure 3 is provided on the top of the housing 9 and the box 8. A shearing structure 7 is provided inside the box 8. An inspection door 10 is installed on the right side of the box 8. The left side of the housing 9 is threadedly connected to a servo motor 4 by bolts.

[0028] The output shaft of the servo motor 4 is fixedly connected to the cutting disc 5. Both sides of the cutting disc 5 are rotatably connected to the housing 9 through bearings. The top of the sleeve 301 is fixedly connected to the mounting plate 1. The inner wall of the housing 8 is fixedly connected to the second shearing blade 6.

[0029] The guide structure 3 includes a sleeve 301. A sealing ring 303 is installed on the lower part of the inner wall of multiple sleeves 301. The sealing ring 303 and the inner wall of the sleeve 301 are slidably connected to the slide rod 302. The lower part of the slide rod 302 is fixedly connected to the housing 9 and the box 8 respectively. When the output end of the electric telescopic rod 2 moves, it drives the housing 9 to move, and at the same time drives the slide rod 302 to slide along the sealing ring 303 and the inner wall of the sleeve 301. The sealing ring 303 can play a sealing role, reducing the entry of dust or concrete residue into the sleeve 301, which may cause jamming during adjustment.

[0030] The shearing structure 7 includes a hydraulic cylinder 701. A slider 702 is fixedly connected to the output end of the hydraulic cylinder 701. A cylinder 703 is fixedly connected to the outer wall of the slider 702. The outer wall of the cylinder 703 is slidably connected to a groove 704. The grooves 704 are machined on the inner wall of the first shearing blade 705. The upper part of the first shearing blade 705 is movably connected to the housing 8 via a pin. The movement of the output end of the hydraulic cylinder 701 drives the slider 702 to move, thereby driving the cylinder 703 to slide along the inner wall of the groove 704. This, in turn, drives the first shearing blade 705 to swing, so as to achieve greater shearing force of the first shearing blade 705 and the second shearing blade 6. It can easily cut large-diameter reinforced concrete frame structures, and to a certain extent, it can improve the applicability of the equipment.

[0031] Working principle:

[0032] When using demolition equipment for reinforced concrete frame structures:

[0033] The operator docks the mounting plate 1 with the external robotic arm. The robotic arm provides the power and positioning functions for the device to move and adjust its angle, ensuring that the device can be accurately aligned with the reinforced concrete frame structure to be demolished.

[0034] When it is necessary to cut the concrete on the outside of the reinforced concrete frame, the operator starts the servo motor 4 (the servo motor 4, the electric telescopic rod 2, and the control valve for opening and closing the hydraulic cylinder 701 are all connected to the controller and the drive board. The drive board drives them to open and close through the buttons on the controller). The output shaft of the servo motor 4 rotates, which drives the cutting disc 5 to rotate. The left electric telescopic rod 2 is started. The output end of the electric telescopic rod 2 moves, which drives the housing 9 to move. At the same time, it drives the slide rod 302 to slide along the sealing ring 303 and the inner wall of the sleeve 301. The sealing ring 303 can play a sealing role to reduce dust or concrete residue from entering the sleeve 301, which may cause jamming during adjustment. The concrete is cut by the cutting disc 5.

[0035] When it is necessary to cut the reinforced concrete frame structure, the operator controls the left electric telescopic rod 2 to reset the housing 9 and shuts off the servo motor 4. Then, the right electric telescopic rod 2 is started, which moves the housing 8. When the reinforced concrete frame structure to be demolished is between the first shearing blade 705 and the second shearing blade 6, the operator shuts off the second electric telescopic rod 2 and starts the hydraulic cylinder 701. The output end of the hydraulic cylinder 701 moves, which moves the slider 702, thereby causing the cylinder 703 to slide along the inner wall of the groove 704. This, in turn, causes the first shearing blade 705 to swing. When the first shearing blade 705 and the second shearing blade 6 come into contact, the excess reinforced concrete frame structure is cut off. This allows for greater shearing force from the first shearing blade 705 and the second shearing blade 6, making it easy to cut larger diameter reinforced concrete frame structures. To a certain extent, this can improve the applicability of the equipment.

[0036] After the excess reinforced concrete frame is sheared, the operator can reset the box 8 by controlling the second electric telescopic rod 2 on the right. When the components inside the box 8 are damaged, the inspection door 10 can be opened for repair.

[0037] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
