Referring to Figures 1-5, a rail clamp for elevator installation and maintenance includes a positioning clip 1, a clamping plate 2 and a support plate 3. specific:

The positioning clip 1 is provided with a connecting groove 4 from its top to the bottom. The mouth of the connecting groove 4 is located on one side of the positioning clip 1 so that the elevator guide rail can be inserted into the connecting groove 4 from this side of the positioning clip 1 .

Both side walls in the connecting groove 4 are inclined surfaces 5, and the two inclined surfaces 5 are symmetrically distributed. The width of the top of the connecting groove 4 is greater than the width of the bottom thereof, so that the entire connecting groove 4 forms a trapezoidal spatial structure.

There are two splints 2. The splint 2 has a beveled surface 6 and a vertical surface. The vertical surface is in the vertical direction. The inclination angle of the beveled surface 6 relative to the vertical surface is consistent with the angle between the inclined surface 5 in the connecting groove 4 and the vertical surface. The inclination angles of the surfaces are equal. The two clamping plates 2 are respectively slidably disposed on the inclined surfaces 5 on both sides of the connecting groove 4, and the beveled surfaces 6 of the two clamping plates 2 are respectively slidably matched with the two inclined surfaces 5 in the connecting groove 4.

Preferably, anti-slip teeth 7 are provided on the vertical surface of the plywood 2 , and reinforcing ribs 8 are disposed between the support plate 3 and the plywood 2 .

There are two support plates 3, and they are respectively installed on a plywood 2. One end of the support plate 3 is fixed on one side of the splint 2, the middle part of the positioning clip 1 is hollow, and the other end of the support plate 3 passes through the positioning clip from the side of the connecting groove 4 away from the mouth. In addition, the board surface of the support plate 3 is on a horizontal plane.

Preferably, a C-shaped connecting plate 9 is provided on the top of the positioning clip 1, and two opposite ends of the connecting plate 9 are respectively provided with a bolt 10.

The working principle of this embodiment is:

Firstly, the positioning clip 1 is set, and a connecting groove 4 is provided in the positioning clip 1. The two inner walls of the connecting groove 4 are inclined surfaces 5. By setting two splints 2 in the connecting groove 4, the beveled surface 6 of the splint 2 is made It is slidably matched with the inclined surface 5 of the connecting groove 4 so that the distance between the vertical surfaces of the two clamping plates 2 can be adjusted. In addition, a support plate 3 is provided on the two clamping plates 2 respectively.

When using this rail clamp, the support plate 3 is abutted against the bottom of the elevator car, and then the elevator guide rail is placed inside the connecting groove 4, and the potential clip is fixed on the elevator track, and finally the two splints 2 are respectively It is arranged on both sides of the elevator track, and the vertical surfaces of the two splints 2 are attached to both sides of the elevator track respectively.

Since the elevator car is heavy, the elevator car has a tendency to press down on the support plate 3. At this time, the support plate 3 drives the plywood 2 to move downward in the positioning clip 1, and passes through the inclined surface 5 in the connecting groove 4 and the plywood. The chamfered surface 6 on 2 makes the two splints 2 approach each other in the connecting groove 4 . At this time, the pressure of the splint 2 on the elevator track increases, causing the friction between the two to increase, thereby supporting the elevator car.

Since this technical solution uses the splint 2 with a larger contact area to connect to the elevator track, it has a larger contact area than the existing technology. On the one hand, the support force is enhanced, and on the other hand, the support force is dispersed in the contact between the splint 2 and the elevator track. On the surface, the practical life of the rail clamp can be effectively increased.

In one specific embodiment:

The top of the splint 2 is vertically provided with a guide rod 15. The guide rod 15 is cylindrical and slides and matches with the guide hole 14.

Preferably, the guide plate 13 has two guide holes 14, and at the same time, the top of the clamping plate 2 has two guide rods 15 that match the two guide holes 14 one by one.

In this embodiment, a guide plate 13 is provided, a guide hole 14 is provided on the guide plate 13, and a guide rod 15 is provided to match the guide hole 14. On the one hand, it is used to limit the movement direction of the clamping plate 2, and on the other hand, it avoids accidental movement. When using this rail clamp, the clamping plate 2 is separated from the positioning clip.

In another specific embodiment:

One end of the guide rod 15 away from the clamping plate 2 is provided with a limit plate 16. The guide rod 15 is covered with a spring 17. One end of the spring 17 is in contact with the limit plate 16, and the other end is in contact with the top surface of the guide plate 13. Each guide rod 15 is provided with a spring 17 .

In another specific embodiment:

A number of balls 18 are provided on the top of the end of the support plate 3 away from the splint 2, and the top surfaces of the balls 18 protrude from the top surface of the support plate 3. By arranging a number of balls 18, the sliding friction between the support plate 3 and the bottom surface of the elevator car can be changed into rolling friction. At the same time, a number of balls 18 can also disperse the pressure of the elevator car.

The above-mentioned embodiments only express specific implementation modes of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the patent scope of the present invention. It should be noted that for those of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present utility model, and these all fall within the protection scope of the present utility model.
