Description

But height-adjusting's hauler frame

Technical Field

The utility model relates to an elevator hauler device especially relates to a but height-adjusting's hauler frame.

Background

The traction type elevator is used as manned or cargo equipment, one side of the traction type elevator is a lift car, the other side of the traction type elevator is a counterweight, and a steel wire rope is driven by a traction machine to enable the lift car to do lifting motion. After the elevator steel wire rope is installed and used, structural extension can be generated due to stress, and after the steel wire rope is extended and deformed, the elevator leveling is inaccurate, people are prevented from getting in and out of the elevator, and certain potential safety hazards exist.

At present, when a steel wire rope is stressed and stretched, the normal use of an elevator is met by shearing the length of the steel wire rope, and the steel wire rope is difficult to shear. However, the steel wire rope is wound on a traction sheave of the traction machine, if the height of the traction machine is correspondingly adjusted after the steel wire rope is stressed and extended, the steel wire rope does not need to be cut, and meanwhile, the elevator can be normally used.

SUMMERY OF THE UTILITY MODEL

The utility model relates to a solve wire rope and can take place the extension after using a period, cause the elevator flat bed inaccurate, provide a but height-adjusting's hauler frame, highly compensate wire rope's elongation through adjusting the hauler.

In order to achieve the above purpose, the utility model adopts the following technical scheme: a traction machine frame with adjustable height comprises a plurality of traction machine frames and a plurality of sets of bolt and nut mechanisms, wherein one set of bolt and nut mechanism comprises a bolt and two sets of nut structures; the bolt penetrates through the rack, one end of the bolt is fixed on the I-beam, the tractor rack is arranged between the two nut structures, the positions of the two nut structures are adjusted, the height of the tractor rack is changed, and the height of the tractor is adjusted.

Preferably, the set of nut structures comprises two nuts, the two nuts being opposite to each other. The rack is placed between two sets of nut structures, the nuts correspondingly bear certain external force, and the reverse nuts are adopted to prevent the phenomenon of thread slipping between the nuts and the bolts.

Preferably, the number of the hoisting machine frames is two, and two sets of bolt and nut mechanisms are arranged on one hoisting machine frame. The height of the tractor frame is adjusted through the two sets of bolt and nut mechanisms, so that the tractor frame is convenient to adjust and is convenient to fix.

Preferably, the two traction machine frames are connected together through the auxiliary beam. The whole tractor frame structure is more stable and reliable.

Preferably, the traction machine frame is provided with two round holes. The bolt can conveniently penetrate through the tractor frame.

Preferably, the traction machine frame and the auxiliary beam are both provided with gradienters. After the height of the tractor frame is adjusted, whether the tractor frame is inclined or not is judged by observing the level gauge.

Preferably, the i-beam is fixed on the bottom surface of the machine room or the wall of the hoistway. The device can be suitable for both an elevator without a machine room and an elevator without the machine room.

The utility model discloses following beneficial effect has: (1) the elongation of the steel wire rope can be overcome by adjusting the height of the traction machine; (2) the whole structure is simple, and the adjustment is convenient; (3) the elevator control method can be applied to both elevators with machine rooms and elevators without machine rooms, and has a good application range.

Drawings

fig. 2 is an enlarged schematic structural diagram of the utility model a.

In the figure: 1-tractor frame, 2-bolt, 3-I-beam, 4-nut, 5-auxiliary beam, 6-round hole, 7-level gauge.

Detailed Description

The invention is further described with reference to the accompanying drawings and the detailed description.

As shown in fig. 1, a traction machine frame with adjustable height comprises a plurality of traction machine frames 1 and a plurality of sets of bolt-nut mechanisms, wherein one set of bolt-nut mechanism comprises a bolt 2 and two sets of nut structures; the bolt 2 penetrates through the rack, one end of the bolt 2 is fixed on the I-beam 3, the tractor rack 1 is arranged between the two sets of nut structures, the positions of the two sets of nut structures are adjusted, the height of the tractor rack 1 is changed, and the height of the tractor is adjusted.

Installation of this implementation: firstly, a group of nut mechanisms are installed on four bolts 2, then the bolts 2 penetrate through round holes 6 of the tractor frame 1, and then the other group of nut mechanisms are installed on the bolts 2, wherein the group of nut mechanisms comprise two nuts 4, reverse nuts are arranged between the two nuts 4, the phenomenon that the nuts 4 slide on the bolts 2 due to stress can be effectively prevented, then the bolts 2 are fixed on the I-shaped beam 3, and meanwhile, the two tractor frames 1 are further fixed by means of auxiliary beams 5, so that the structure of the whole tractor frame 1 is more stable and reliable. The i-beam 3 is mounted on the floor of the machine room or on the hoistway wall of the hoistway.

The application of the implementation is as follows: when a new elevator is used for a certain time, the steel wire rope can be lengthened due to stress, so that the elevator is inaccurate in leveling, and measures are required to be taken to solve the problem that the elongation of the steel wire rope is caused. The utility model discloses an adjust the problem that the extension volume that highly solves wire rope of hauler brought, at first loosen two nuts 4 of 1 top of hauler frame are whole, and two nuts 4 are reverse nuts, so when loosening and fastening two nuts 4 revolve to be different. After the nut 4 above the traction machine is loosened, the nut 4 below the traction machine frame 1 is pushed upwards to increase the height of the whole traction machine frame 1, and when the traction machine frame 1 is adjusted, the level gauge 7 can be observed to judge whether the traction machine frame 1 is inclined. After the height of the tractor frame 1 is adjusted, the nut 4 above the tractor frame 1 is locked, and an effective fixing effect is achieved on the tractor frame 1.

If the adjustment of the device can not compensate the elongation of the steel wire rope, the steel wire rope needs to be sheared, the height of the tractor can be reduced when the shearing amount is too large in the shearing process, firstly, the nut 4 above the tractor frame 1 is loosened, then the nut 4 below the tractor frame 1 rotates downwards, the once descending amount of the nut 4 is not easy to be too large, the tractor frame 1 can descend by the gravity of the tractor frame when the nut 4 descends, and when the adjustment is completed, the nut 4 above the tractor frame 1 is locked.
