Description

Technical Field

[0001] The utility model relates to the technical field of bridge supports, in particular to a road bridge support maintenance device. Background Art

[0002] As an important structural component connecting the upper and lower structures of a bridge, the bridge bearing has the main function of reliably transmitting the load and deformation (displacement and rotation) borne by the upper structure of the bridge to the lower structure of the bridge. It is an important force transmission device of the bridge. As we all know, bridge bearings need to be maintained regularly, and the maintenance of bridges is roughly as follows: the various parts of the bearings should be kept intact and clean, or a layer of lubricating oil should be regularly applied to the rolling surface of the rolling bearings, and the rolling surface should be wiped clean before oiling. The steel bearings should be rust-proofed and corrosion-proofed. Except for the steel rollers and rolling surfaces, the rest of the bearing parts should be painted for protection. When rusting, the bridge bearings need to be polished. Therefore, a road bridge bearing maintenance device is needed.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Example

[0020] See also Figure 1 - Figure 3 The utility model provides a technical solution: a road bridge support maintenance device, including a box body 1, a lifting component 2 is slidably connected inside the box body 1, a device box 3 is fixedly connected to the outside of the lifting component 2, a moving component 4 is connected to the inside of the device box 3, a protective box 5 is fixedly connected to the top of the moving component 4, a grinding component 6 is fixedly connected to the top of the protective box 5, and a dust suction component 7 is fixedly connected to the inside of the protective box 5. Through the cooperation of the lifting component 2, the moving component 4, the grinding component 6 and the dust suction component 7, it is achieved that the staff does not need to hold the device body for a long time to perform the grinding work, which not only reduces the labor of the staff, but also improves the grinding efficiency of the device body. The lifting component 2 includes The electric telescopic rod 21 is slidably connected to the inside of the box body 1, and the outside of the box body 1 is fixedly connected to a U-shaped bracket 22, and the inside of the U-shaped bracket 22 is rotatably connected to a connecting piece 24, and the outside of the connecting piece 24 and the inside of the U-shaped bracket 22 are fixedly connected to a lifting frame 23, and the outside of the lifting frame 23 is fixedly connected to the top of the electric telescopic rod 21. When the electric telescopic rod 21 is started, when the electric telescopic rod 21 moves upward, the lifting frame 23 is driven to rotate in the U-shaped bracket 22 away from the box body 1 through the connecting piece 24, so that the lifting frame 23 moves upward away from the end of the U-shaped bracket 22. At this time, the grinding disc 62 is lifted to the position where grinding is required through the lifting assembly 2.

[0021] Furthermore, the moving component 4 includes a first motor 41, which is fixedly connected to the outside of the equipment box 3. The inside of the equipment box 3 is rotatably connected to a reciprocating screw 42, and one end of the reciprocating screw 42 is fixedly connected to the output end of the first motor 41. The external thread of the reciprocating screw 42 is connected to a reciprocating slider 43, and the top of the reciprocating slider 43 is fixedly connected to the bottom of the protective box 5. The reciprocating screw 42 in the equipment box 3 is driven to rotate by the first motor 41. When the reciprocating screw 42 rotates, it will drive the reciprocating slider 43 outside the reciprocating screw 42 to move in parallel.

The dust generated during grinding will be sucked into the dust box 71 from the inlet of the dust collection box 73 by starting the fan 72, and the dust will be collected centrally by the fan 72, thereby avoiding the situation where dust flies all over the sky during grinding, thereby improving the quality of the working environment.

[0023] In summary: when in use, the device body is moved to the place of use, and then the electric telescopic rod 21 is started. When the electric telescopic rod 21 moves upward, it will drive the lifting frame 23 to rotate in the U-shaped bracket 22 in the direction away from the box body 1 through the connecting piece 24, so that the lifting frame 23 moves upward away from the end of the U-shaped bracket 22. At this time, the grinding disc 62 is raised to the position where grinding is required through the lifting component 2, and at the same time, the second motor 61 is started, and the grinding disc 62 is driven by the second motor 61 to grind its bridge support, and then the first motor 41 is started, and the reciprocating screw rod 42 in the device box 3 is driven to rotate by the first motor 41. When the reciprocating screw rod 42 rotates, it will drive the reciprocating screw rod 4 2 The reciprocating slider 43 outside moves in parallel. When the reciprocating slider 43 moves, it will drive the grinding disc 62 to grind repeatedly, thereby accelerating the grinding speed and improving the grinding efficiency. The dust generated during the grinding will be sucked into the dust collecting box 71 from the inlet of the dust collecting box 73 by starting the fan 72, so as to be collected centrally, thereby avoiding the situation that dust flies all over the sky during grinding, thereby improving the quality of the working environment. Therefore, through the cooperation of the lifting component 2, the moving component 4, the grinding component 6 and the dust collecting component 7, it is realized that the staff does not need to hold the device body for a long time to perform grinding work, which not only reduces the labor of the staff, but also improves the grinding efficiency of the device body.
