Description

TECHNICAL FIELD

[0001] The utility model relates to an improvement of counterweight structure, in particular to a steel wire rope anti-off groove device on counterweight wheel. BACKGROUND

[0002] The counterweight device of the elevator is the counterweight structure opposite to the elevator car, and the counterweight device realizes up and down running by passing through the steel wire rope. The steel wire rope realizes the purpose of traction by the working effect of the dynamic pulley generated by the counterweight rope wheel. Multiple steel wire ropes are usually arranged on the counterweight rope wheel to form a multiple winding structure, which can increase the traction ratio. Therefore, the multiple passing steel wire ropes need to be kept in the corresponding rope groove to avoid the problem of off groove, otherwise, problems such as traction failure and structure wear will occur. The structure of the counterweight structure is compact, and there are few fixed bases, so it is not convenient to set the anti-off groove structure, and therefore structural improvement is needed. SUMMARY

[0003] The utility model aims at overcoming the above-mentioned insufficient in prior art, and provides a steel wire rope anti-off groove device on counterweight wheel.

[0004] The utility model discloses a technical scheme that solves the above-mentioned problem: the anti-off groove device includes a limiting side plate and a limiting bottom plate. The limiting side plate is a structure arranged oppositely and is arranged on both sides of the counterweight wheel. The counterweight wheel is connected to the counterweight frame through a shaft mounting structure. The limiting side plate is fixedly installed on the counterweight frame. The limiting bottom plate is fixedly connected to the lower part of the limiting side plate. The limiting bottom plate is shaped as a "N" section structure, and its two ends are fixedly connected to the limiting side plates on both sides. The bottom plate part of the limiting bottom plate is arranged close to the edge of the counterweight wheel and forms an anti-off groove gap. The distance of the anti-off groove gap is smaller than the diameter of the steel wire rope. By arranging the limiting side plate on both sides of the counterweight wheel on the counterweight frame, the adjacent structure of the side edge is formed, and a small space limiting structure is formed through the limiting bottom plate, which can effectively avoid the problem of off groove of the steel wire rope, effectively improve the safety of the elevator work, and make the overall structure lightweight and compact without affecting the normal operation of the counterweight frame.

[0005] Further, the limiting side plate is provided with an emptying opening corresponding to the shaft part of the counterweight wheel. The two sides of the emptying opening are formed with a connecting body. The upper edge of the connecting body is formed with a mounting plate fixed to the bottom of the counterweight frame. The emptying opening is used to avoid the shaft part structure of the counterweight wheel to form a closer structure. The connecting body is fixedly connected to the counterweight frame upward to form reliable fixation and effectively improve the safety of the rope wheel work.

[0006] Further, the limiting bottom plate is formed by bending a plate material. The limiting bottom plate is fixedly connected to the limiting side plate through a fixing screw. The limiting bottom plate is directly formed by bending a plate material, which is convenient for processing and installation and has good structural strength and good limitation to the steel wire rope.

[0007] Further, the center axis of the counterweight wheel is connected to the counterweight frame through an axle part fixing member, and the limiting bottom plate is arranged corresponding to the axis of the counterweight wheel.

[0008] Compared with the prior art, the present application has the following advantages and effects: the present application is an improved anti-off-groove structure on the counterweight wheel of an elevator, has a light overall structure, is compact in structure, is convenient to fix and install, can be adapted to counterweight wheels of different specifications, and is convenient to check and maintain.
