In order to adjust the grinding depth, a hollow pipe 19 is sleeved at the left end of the pull rod 18, the hollow pipe 19 is in threaded connection with the pull rod 18, the hollow pipe 19 is rotationally fixed on the vertical plate 12, and a bearing is arranged between the hollow pipe 19 and the vertical plate 12.

In order to install the polishing disc 13, a cylindrical block 20 coaxial with the rotating shaft 8 penetrates through the vertical plate 12, a bearing is installed between the cylindrical block 20 and the vertical plate 12, a spline hole is formed in the left end of the cylindrical block 20, a spline shaft 21 is fixed at the right end of the rotating shaft 8, and the spline shaft 21 slides in the spline hole; the right end of the cylindrical block 20 is provided with a mounting hole, and the central shaft of the polishing disc 13 is inserted in the mounting hole.

The first bevel gear 2 is connected with a motor 22, and the motor 22 is fixed at the left end of the rectangular box 1.

It is worth noting that the grinding disc 13 is in a circular truncated cone shape, and the diameter of one end close to the building surface is smaller than that of the other end, so that the grinding disc 13 is prevented from being damaged in the process that the rectangular box 1 moves along the gear; a bearing is arranged between the hollow tube 19 and the vertical plate 12, and the elasticity of a first pressure spring between the vertical plate 12 and the rectangular box 1 is far greater than that of a third pressure spring on the sliding plate; a linear bearing is arranged between the sliding block 15 and the sliding plate, two gears are arranged, and the two gears can walk on the rack 7 more stably; in order to enable the rectangular box to stably move forwards, two clamping holes are formed in each sliding plate and distributed left and right, when the movable plate 11 is meshed with the first end face gear 9, the upper end of the pin is placed in the clamping hole on the right side, and when the movable plate 11 is meshed with the second end face gear 10, the upper end of the pin is placed in the clamping hole on the left side.

When the device is used, the end parts of the guide rod 14 and the rack 7 in the device are fixed on the surface of a building, the rectangular box 1 is moved to the end part, the surface of the building is not polished in an initial state, the surface of the building is propped against the polishing disc 13, at the moment, a first pressure spring between the vertical plate 12 and the rectangular box 1 is compressed, gear teeth at the upper end of the movable plate 11 are meshed with the second end face gear 10, the shell 3 is fixed and does not rotate, then a power supply of the motor 22 is turned on, the motor 22 drives the first bevel gear 2 to rotate, the first bevel gear 2 drives the second bevel gear 4 to rotate through the plurality of third bevel gears 5, the second bevel gear 4 drives the rotating shaft 8 to rotate, the rotating shaft 8 drives the cylindrical block 20 to rotate through the spline shaft 21, and the cylindrical block 20 drives the polishing disc; after the building surface is polished after a period of time, the polishing disc 13 moves rightwards under the action of a first pressure spring, at the moment, the vertical plate 12 drives the pulling plate to move rightwards, the pulling rod 18 pulls the sliding plate through a tension spring, when the force received by the sliding plate is large enough, the pin is forced to be pressed into the small hole, the sliding plate is pulled rightwards, the sliding plate moves rightwards, the L-shaped rod on the sliding plate pushes the movable plate 11 to swing rightwards and engage with the first end face gear 9, at the moment, the rotating shaft 8 is fixed, the shell 3 starts to rotate, the shell 3 rotates and drives the gear to roll on the rack 7 through the gear ring 6, so that the whole rectangular box 1 moves along the rack 7, as the polishing disc 13 does not rotate at the moment, and as the polishing disc 13 is in a circular table shape, the polishing disc 13 can move along the rectangular box 1, when the polishing disc 13 reaches the surface of an area to be polished, the building surface forces the polishing disc, at this time, the housing 3 is fixed, the rotating shaft 8 starts to drive the polishing disc 13 to rotate again, the next cycle is started, when the rectangular box 1 moves to the other end of the guide rod 14, the power supply of the motor 22 is cut off, polishing is stopped, and polishing of the next area is prepared.

If the polishing depth needs to be adjusted, the hollow tube 19 on the pull rod 18 can be screwed, the hollow tube 19 rotates to drive the pull rod 18 to move left and right, so that the pre-tightening force of the third pressure spring on the sliding plate can be adjusted, and the purpose of adjusting the polishing depth is finally achieved.

The invention has the outstanding advantages and remarkable progress that:

1. according to the invention, the rack 7 and the guide rod 14 are utilized to preset the moving track of the rectangular box 1, and on the basis, the polishing is stopped after the polishing disc 13 polishes for a certain depth, so that the building surface after polishing is effectively ensured to be positioned on the same plane, and the later-stage steel plate adhesion is facilitated.

2. According to the invention, the power switching is realized by utilizing the left and right movement of the movable plate 11, the forward movement along the rack 7 after polishing for a certain depth is realized, the polishing is in place at one time, the influence of human factors is avoided, and the polishing effect is ensured.

3. The guide rod 14 and the rack 7 are fixed in the polishing area in advance, so that the device can polish both the bottom of a building beam and the side wall of a pier, and a worker only needs to control the motor 22 in the polishing process, so that the adverse effect of dust generated by polishing on the worker is reduced.
