Description

Technical Field

[0001] The invention relates to the technical field of elevators, and in particular to a combined guide rail clamp and an elevator. Background Art

[0002] With the widespread application of elevator products, the market has higher and higher requirements for the safety and reliability of elevators. In particular, for high buildings, due to the shrinkage of building concrete and geological reasons, the building may sink during use. When the building is sinking, the retaining force between the guide rail clamp and the guide rail is too large, causing the elevator guide rail to deform.

[0003] In the current existing technology, there are many forms of guide rail clamps, such as forged, cast guide rail clamps, "Z"-shaped guide rail clamps, etc. However, all types of guide rail clamps generally have the problem of excessive holding force. When the elevator is in use, the guide rails are prone to bending and deformation, affecting the riding comfort, and there are also safety hazards. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a combined guide rail clamp and an elevator to solve the problem that the existing elevator guide rails are bent and deformed due to building settlement, so as to make the elevator safer and more reliable.

[0005] The technical problem to be solved by the present invention can be achieved by the following technical solutions:

[0006] A combined guide rail clamp comprises an upper clamping plate and a lower clamping plate, wherein the upper clamping plate and the lower clamping plate are locked on a guide rail bracket by fasteners, wherein the lower clamping plate is tightly attached to the side surface of the bottom of the guide rail from a first direction; the upper clamping plate is pressed against the inclined surface of the side surface of the bottom of the guide rail from a second direction; the first direction and the second direction are perpendicular to each other.

[0007] In a preferred embodiment of the present invention, a protrusion is provided on the upper clamping plate at a position corresponding to the inclined surface of the bottom of the guide rail, and the protrusion presses against the inclined surface of the bottom of the guide rail from the second direction.

[0008] In a preferred embodiment of the present invention, the surface of the protrusion is arc-shaped.

[0009] In a preferred embodiment of the present invention, the upper clamping plate is a flat plate structure or a bent structure.

[0010] In a preferred embodiment of the present invention, the lower clamping plate adopts a U-shaped lower clamping plate, and the upper clamping plate is located between the two side walls of the lower clamping plate of the U-shaped structure; the tiger's mouth part on one side of the lower clamping plate of the U-shaped structure is tightly attached to the side of the bottom of the guide rail from the first direction.

[0011] In a preferred embodiment of the present invention, a protrusion is provided on both side walls of the lower clamping plate of the U-shaped structure corresponding to the bottom side of the guide rail, and a certain gap is left between each protrusion and the inclined surface of the bottom of the guide rail in the second direction.

[0012] In a preferred embodiment of the present invention, the fastener includes a special-shaped bolt and a nut, and through holes matching the special-shaped bolt are opened on the bottom walls of the upper clamp plate and the lower clamp plate of the U-shaped structure. The special-shaped bolt passes through the through holes on the bottom walls of the upper clamp plate and the lower clamp plate of the U-shaped structure and the through holes on the guide rail bracket and is locked by the nut.

[0013] The elevator of the present invention comprises the above-mentioned combined guide rail clamp

[0014] Due to the adoption of the above technical solution, the lower clamping plate of the present invention is tightly attached to the side surface of the bottom of the guide rail from the first direction to limit the sliding of the guide rail in the first direction. When the elevator is operating normally, the upper clamping plate is slightly pressed against the inclined surface of the bottom of the guide rail from the second direction, so that there is a small holding force between the upper clamping plate and the inclined surface of the bottom of the guide rail; when the guide rail is subjected to abnormal force, the upper clamping plate and the lower clamping plate successively or jointly limit the sliding and turning of the guide rail, and always keep the guide rail in an effective working position.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below with reference to specific diagrams.

[0022] See also Figures 1 to 5The combined rail clamp shown in the figure includes an upper clamping plate 10, a lower clamping plate 20, a special-shaped bolt 30 and two nuts 40, 50. The rail 60 is connected to the rail bottom 70 in a vertical state. The side of the rail bottom 70 opposite to the rail 60 is an inclined surface 71.

[0023] The upper clamping plate 10 is a flat plate structure or a bent structure. A protrusion 11 is arranged on the upper clamping plate 10 at a position corresponding to the inclined surface 71 of the guide rail bottom 70, and a through hole 12 is provided at an appropriate position of the upper clamping plate 10. The surface of the protrusion 11 is arc-shaped.

[0024] The lower clamping plate 20 is a U-shaped structure, which has two side walls 21, 22 and a bottom wall 23 connected to the two side walls 21, 22 as a whole, and a through hole 23a is provided at an appropriate position of the bottom wall 23. In addition, a protrusion 21a, 22a is provided on one side of the two side walls 21, 22 corresponding to the guide rail bottom 70. The protrusion 21a, 22a and the thumb portion 24 on the side of the lower clamping plate 20 corresponding to the guide rail bottom 70 are smoothly transitioned.

[0025] The special-shaped bolt 30 has two bolt sections 31 and 32 connected as one and a partition 33 between the two bolt sections 31 and 32. The two bolt sections 31 and 32 are coaxial with the partition 33. With such a special-shaped bolt 30, the torque imbalance of the two bolt sections 31 and 32 can be offset.

[0026] During installation, the bolt 31 of the special-shaped bolt 30 is passed through the through hole 22a on the bottom wall 23 of the lower clamping plate 20 and the through hole 81 on the guide rail bracket 80 in sequence, and then the flat washer 91 and the spring washer 92 are put on, and then the nut 40 is locked on the bolt 31. Then, the upper clamping plate 10 is placed between the two side walls 21 and 22 of the lower clamping plate 20, and the bolt 32 is passed through the through hole 12 on the upper clamping plate 10, and then the nut 50 is locked on the bolt 32, so that the upper clamping plate 10 and the lower clamping plate 20 are locked on the guide rail bracket 80 by the fastener composed of the special-shaped bolt 30 and the nuts 40 and 50. The upper clamping plate 10 is separated from the bottom wall 23 of the lower clamping plate 20 by the partition 33 in the special-shaped bolt 30, and the length of the partition 33 is adjusted as needed.

[0027] Before tightening the nuts 40 and 50, adjust the position of the lower clamping plate 20 so that the jaws 24 of the lower clamping plate 20 are moved from the first direction (i.e. Figure 1 The nut 40 is tightly attached to the side wall 72 of the guide rail bottom 70, and the torque of the nut 40 is adjusted to limit the horizontal sliding of the guide rail 60. Then, the position of the upper clamping plate 10 is adjusted so that the protrusion 11 of the upper clamping plate 10 is moved from the second direction (i.e. Figure 1 Finally, the torque of the nut 50 is adjusted so that the raised portion 11 of the upper clamping plate 10 is moved from the second direction (i.e., the vertical direction in the middle) to the inclined surface 71 of the guide rail bottom 70. Figure 1 The upper clamping plate 10 is slightly pressed against the inclined surface 71 of the guide rail bottom 70 (in the vertical direction), so that there is a small holding force between the upper clamping plate 10 and the guide rail bottom 70. At the same time, a certain gap A is ensured between the protrusions 21a, 22a on the two side walls 21, 22 of the lower clamping plate 20 and the inclined surface 71 of the guide rail bottom 70 in the second direction, so that the protrusions 21a, 22a will not contact the inclined surface 71 of the guide rail bottom 70.

[0028] The present invention can also be extended as follows: the lower clamping plate 20 and the special-shaped bolt 30 are designed as an integral whole.

[0029] The base 24 of the lower clamping plate 20 of the present invention is arranged in a first direction (i.e. Figure 1 The guide rail 60 is attached to the side wall 72 of the guide rail bottom 70 to limit the guide rail 60 from moving in the first direction (i.e., Figure 1 In addition, when the elevator is operating normally, the raised portion 11 of the upper clamping plate 10 moves from the second direction (i.e. Figure 1 The upper clamping plate 10 and the lower clamping plate 20 are slightly pressed against the inclined surface 71 of the bottom 70 of the guide rail, so that there is a small holding force between the protrusion 11 of the upper clamping plate 10 and the inclined surface 71 of the bottom 70 of the guide rail; when the guide rail 60 is subjected to abnormal force, the upper clamping plate 10 and the lower clamping plate 20 successively or jointly limit the sliding and turning of the guide rail 60, and always keep the guide rail 60 in the effective working position.
