[0033] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] Embodiment 1

[0035] See also Figure 1 - Figure 6 , an elevator safety clamp device, comprising: a safety clamp body 1, a mounting frame 2 is fixedly mounted at the bottom of the safety clamp body 1, two first U-shaped plates 3 are arranged on the inner side of the mounting frame 2, two brush rollers 4 and a rotating roller 5 are arranged on the inner sides of the two first U-shaped plates 3 from top to bottom, and both ends of the brush roller 4 and the rotating roller 5 are rotatably connected to the first U-shaped plates 3;

[0036] A synchronous wheel 6 is fixedly mounted on one end of the brush roller 4 and the rotating roller 5, and a plurality of synchronous wheels 6 are connected by tensioning and meshing with a synchronous belt;

[0037] Four T-shaped rods 10 are fixedly mounted on one side of the first U-shaped plate 3, and the four T-shaped rods 10 are arranged in groups of two on both sides of the synchronous belt;

[0038] An elastic component 7, the elastic component 7 is arranged on the inner side of the mounting frame 2, and the first U-shaped plate 3 is fixedly mounted on the elastic component 7;

[0039] A second U-shaped plate 8 is fixedly mounted on the inner side wall of the mounting frame 2, and the second U-shaped plate 8 is located above the elastic component 7 and the first U-shaped plate 3;

[0040] The oiling assembly 9 is arranged above the second U-shaped plate 8 .

[0041] The utility model provides an elevator safety clamp device. When in use, the brush roller 4 and the rotating roller 5 in the first U-shaped plate 3 can contact the elevator guide rail through the elastic component 7. Then, as the elevator rises and falls, the safety clamp body 1 can drive the mounting frame 2, the elastic component 7, the first U-shaped plate 3, the brush roller 4 and the rotating roller 5 to rise and fall synchronously, so that the brush roller 4 can clean the elevator guide rail. At the same time, since the rotating roller 5 is in contact with the guide rail, when the safety clamp body 1 drives the mounting frame 2 to rise and fall along the guide rail, the rotating roller 5 in contact with the guide rail is frictionally moved. Under the action of force, it will rotate, and then the rotating roller 5 will synchronously drive the synchronous wheel 6 at one end thereof, so that the synchronous wheel 6 will drive the synchronous wheel 6 on the brush roller 4 under the action of the synchronous belt, so that the brush roller 4 can rotate, thereby improving the cleaning effect. While cleaning, the T-shaped rods 10 on both sides of the synchronous belt can ensure that the synchronous belt can be in close contact with the synchronous wheel 6. Finally, the oiling component 9 installed on the second U-shaped plate 8 can be oiled and lubricated to the guide rail, thereby reducing the friction between the guide rail and the car, etc., and reducing the noise generated during the operation of the elevator.

[0042] Furthermore, the elastic component 7 includes two third U-shaped plates 71 fixedly installed on both sides of the inner wall of the mounting frame 2, rectangular grooves 73 are opened on both sides of the third U-shaped plate 71, and limit blocks 74 are fixedly installed on both sides of the first U-shaped plate 3, and the limit blocks 74 are plugged into the rectangular grooves 73, and a spring 72 is fixedly installed on one side of the two third U-shaped plates 71, and the other end of the spring 72 is in contact with the first U-shaped plate 3.

[0043] Specifically, the first U-shaped plate 3 is pushed by the spring 72, so that the first U-shaped plate 3 can move stably under the action of the rectangular groove 73 and the limit block 74, thereby ensuring that the brush roller 4 and the rotating roller 5 can contact the guide rail.

[0044] Furthermore, the oiling assembly 9 includes two oil tanks 91 fixedly mounted on the top of the second U-shaped plate 8, a fixing frame 92 is fixedly mounted on one side of the two oil tanks 91, a first sponge 93 is fixedly mounted on the inner side of the two fixing frames 92, and a plurality of circular holes 94 are opened on one side of the oil tanks 91, and the circular holes 94 are located on the inner side of the fixing frame 92.

[0045] Specifically, the oil in the oil tank 91 can flow out through the circular hole 94 on the oil tank 91 and be absorbed by the first sponge 93. Then, as the elevator and the safety clamp body 1 rise and fall, the first sponge 93 can evenly apply the oil to the guide rail, thereby reducing the friction between the guide rail and the car, etc., and reducing the noise generated during the operation of the elevator, thereby increasing the service life of the elevator and the guide rail.
