Detailed Description

As shown in fig. 1 to 3, an arc-shaped ceiling polishing device comprises two parallel-arranged filler strips 1, guide rails 2 and a rack 33 are fixedly arranged on the filler strips 1, a plurality of sliders 21 are arranged on each guide rail 2, each slider 21 is connected to a filler plate 4, a driving motor 3 and a speed reducer 31 are arranged on the filler plates 4, the driving motor 3 is connected with one end of the speed reducer 31, a gear 32 is arranged at the other end of the speed reducer 31, the gear 32 is meshed with the rack 33, a plurality of telescopic rods 6 are vertically connected to the filler plates 4, the upper ends of the telescopic rods 6 are connected with a top plate 7, a plurality of jacks 5 are arranged between the top plate 7 and the filler plates 4, a polishing mechanism 8 is arranged on the top plate 7,

grinding machanism 8 includes support 81 of fixed connection on roof 7, install gear motor 82 on support 81, fixedly connected with crank 821 on gear motor 82 output shaft, install at crank 821 one end and roll round pin 822, a plurality of axle beds 84 of support 81 lower extreme fixedly connected with, pivot 85 is installed in each axle bed 84, the pivot 85 both ends all are located outside roof 7, be equipped with a rocking plate 83 respectively in roof 7 both sides, two rocking plate 83 lower extremes respectively with pivot 85 both ends fixed connection, connect through connecting rod 87 between two rocking plates 83, an arc 86 that is used for pasting abrasive paper is all installed to each rocking plate 83 upper end, set up a spout 831 on one of them rocking plate 83, roll round pin 822 and insert in spout 831.

The using method and the working principle of the invention are as follows:

firstly, laying two cushion strips 1 on the ground along the axis of an arc-shaped suspended ceiling, then assembling a cushion plate 4, a sliding block 21, an expansion rod 6, a jack 5 and the like on a guide rail 2, and ensuring that a gear 32 is meshed with a rack 33; the sanding mechanism 8 is then assembled to the backing plate 4 and coarse and fine sandpaper is applied to each of the two arcuate plates 86.

And secondly, manually shaking each jack 5 to push the telescopic rod 6 to extend so that the abrasive paper is abutted against the arc-shaped hoisting top.

Thirdly, after the driving motor 3 and the reducing motor 82 are started, the worker leaves the room to be polished, and at the moment, the driving motor 3 drives the gear 32 to rotate on the rack 33 through the reducing gear, so that the backing plate 4 is translated along the guide rail 2; the gear motor 82 drives the rolling pin 822 to move up and down in the sliding groove 831 through the crank 821, so that the two rocking plates 83 swing left and right around the rotating shaft 85, and sand paper is adhered to the arc-shaped plate 86 to polish the arc-shaped suspended ceiling.

And fourthly, after the arc-shaped suspended ceiling is polished, enabling a worker to enter a room, detaching the device, and polishing the arc-shaped suspended ceiling in the next room according to the first step to the third step.

The arc 86 is fixedly connected to the upper end of the rocking plate 83 through an elastic device 9, the elastic device 9 comprises an arc supporting plate 91 fixedly connected to the upper end of the rocking plate 83, and the supporting plate 91 is connected with the arc 86 through a plurality of springs 92. Sometimes there are some errors in the arc furred ceiling shape, just so lead to arc layer board 91 to hug closely on the furred ceiling arc easily, just this moment can pass through resilient means 9 to make arc 86 support in real time and lean on the furred ceiling arcwall face, validity when guaranteeing to polish.

Guide sections 861 with one ends bent inwards are arranged at both ends of the arc-shaped plate 86. The guide section 861 has a guide effect, and prevents the arc-shaped plate 86 from being blocked by the protrusion on the arc-shaped surface of the ceiling in the process of swinging left and right.
