The compound boots of leading of elevator
Technical field
The utility model relates to the boots of leading that a kind of elevator uses.
Background technology
In the prior art, elevator lead that boots are divided into sliding guide shoe and boots two classes are led in rolling, sliding guide shoe simple in structure, easy to maintenance, but in running process of elevator, no matter the shoe guide of elevator is iron, firm or nylon, always has friction force to exist between shoe guide and the guide rail, not only having increased the load of elevator traction machine, is again to cause one of the vibration of car and reason of noise.
Summary of the invention
The purpose of this utility model provides a kind of compound boots of leading of leading the friction force between boots and the guide rail that reduce elevator.
To achieve the above object, the technical solution of the utility model is: a kind of compound boots of leading of elevator, it comprises and is arranged on leading the boots seat, be arranged on described boots head of leading on the boots seat on car or the counterweight, described boots head comprises with described leads the U-shaped shoe guide frame that the boots seat is connected, a sidewall of described U-shaped shoe guide frame is provided with the wheel shaft that at least one is parallel to this sidewall and horizontal surface, be arranged with roller on described wheel shaft, two other adjacent madial wall of described U-shaped shoe guide frame is provided with shoe guide.
Have screw on the described shoe guide, passed screw in the described screw, described U-shaped shoe guide frame is connected by described screw with described shoe guide.
Described leading on the boots seat has screw, passed bolt in the described screw, and an end of described bolt and described U-shaped shoe guide frame are inconsistent.
The utility model has the advantages that: because a sidewall of described U-shaped shoe guide frame is provided with the wheel shaft that at least one is parallel to this sidewall and horizontal surface, on described wheel shaft, be arranged with roller, two other adjacent madial wall of described U-shaped shoe guide frame is provided with shoe guide, make the compound existing slipper of boots of leading that the rolling part be arranged again, when elevator moves, reduced to lead the friction force between boots and the guide rail.

The specific embodiment
The compound boots of leading of elevator as shown in Figures 1 and 2, it comprises and is arranged on leading boots seat 4, be arranged on described boots head 7 of leading on the boots seat 4 on car or the counterweight, described boots head 7 comprises with described leads the U-shaped shoe guide frame 3 that boots seat 4 is connected, a sidewall of described U-shaped shoe guide frame 3 is provided with at least one wheel shaft that is parallel to this sidewall and horizontal surface 9, on described wheel shaft 9, be arranged with roller 1, two other adjacent madial wall of described U-shaped shoe guide frame 3 is provided with shoe guide 2, makes the compound existing rolling part of boots of leading that slipper be arranged again.When elevator moved, described shoe guide 2 all was close on the surface of guide rail 8 with the outside face of described roller 1, has reduced the friction force between boots head 7 and the guide rail 8.
Have screw on the described shoe guide 2, passed screw 5 in the described screw, described U-shaped shoe guide frame 3 is connected by described screw 5 with described shoe guide 2, by the distance between screw 5 scalable shoe guides 2 and the guide rail 8.
Described leading on the boots seat 4 has screw, passed bolt 6 in the described screw, and an end of described bolt 6 and described U-shaped shoe guide frame 3 are inconsistent, by the distance between bolt 6 scalable U-shaped shoe guide framves 3 and the guide rail 8.
