Description

Manned traction lift for construction

technical field

The utility model relates to an elevator, in particular to a traction-type elevator for construction that can carry people.

Background technique

At present, the driving mode of construction elevators generally uses rack and pinion transmission or hoist transmission. Rack and pinion transmission, the driving device is connected with the cage, which increases the invalid load and wastes the driving power; most of the hoist transmission mode adopts single-rope traction, which does not meet the requirements of the national standard GB10055-88 safety rules for construction hoists that the manned hoist is independent of each other There is a safety regulation that there must be no less than 2 hoisting wire ropes, and the structure of the winch pulled by double-rope wire ropes is responsible, which is difficult to realize and widely popularize. This shows that there are many defects in the above-mentioned existing construction elevator, and the use effect is not ideal enough.

Contents of the invention

The purpose of the utility model is to solve the deficiencies and problems existing in the above-mentioned prior art, and to provide a traction-type elevator for construction that can carry people. The elevator has reasonable structural design, high working efficiency and good safety.

The technical scheme of the utility model is as follows:

The utility model construction traction type elevator that can carry people up includes the elevator derrick, the hanging cage, the derrick sky beam, the traction drive device and the anti-falling safety device, the elevator sky beam is fixed on the top of the derrick, and the traction drive device It includes traction machine, traction wire rope and guide wheel. The traction machine is fixedly installed on the derrick sky beam. One end of the traction wire rope is fixed on the wire rope fixing frame on the top of the cage, and the other end is fixed on the tensioning device through the guide wheel. On the heavy frame, the elevator is driven by the traction force between the traction wire rope and the traction wheel to make the cage move up and down.

The further technical scheme of the traction type elevator that can carry people on the construction of the utility model is: the safety device for preventing falling includes a speed limiter, a safety gear, a safety gear connecting rod, a buffer and a terminal overrunning protection device. The safety gear is fixed on the top of the derrick, and the safety gear is fixed on the bottom beam of the cage. When the running speed of the elevator reaches or exceeds the set limit value, the speed limiter stops and the safety gear acts to make the cage stop on the guide rail; A further technical solution is the empty sleeve tensioning device under the speed governor to ensure sufficient friction between the wire rope and the speed governor, and the safety gear connecting rod is installed on the top beam of the cage.

In the traction lifter of the utility model that can carry people, the derrick of the elevator is provided with a derrick guide rail, and the four guide shoes installed under the upper beam of the hanging cage and the seat of the safety gear are slidably connected with the derrick guide rail. .

The beneficial effects of the utility model are:

The utility model can carry people up and down the traction type elevator for construction, which has simple and reasonable structure, convenient installation and disassembly, high work efficiency, good safety performance, convenient manufacture and low cost, and can be widely used in the fast and convenient transportation of materials or personnel in the construction industry. transportation.

The traction machine is fixed on the derrick sky beam, one end of the traction wire rope is fixed on the wire rope fixing frame on the top of the cage, and the other end is fixed on the tensioning counterweight frame. The speed governor fixed on the top of the derrick is linked with the safety gear connecting rod fixed on the top beam of the cage and the safety gear fixed on the bottom beam of the cage to make the cage stop effectively.

Detailed ways

Below in conjunction with accompanying drawing, technical content of the present utility model is described:

As shown in Fig. 1, Fig. 2, and Fig. 3, a kind of traction type elevator that can carry people for construction of the present invention is composed of elevator derrick 1, traction driving device 2, anti-falling safety device 3, hanging cage 4, etc. composition. The elevator sky beam 5 is fixed on the top of the derrick, and the traction driving device 2 includes a traction machine, a traction wire rope 6 and a guide wheel 7 . One end of the traction wire rope is fixed on the wire rope fixing frame 8 on the top of the cage, and the other end is fixed on the tensioning weight frame 9 to make the cage 4 move up and down. The anti-falling safety device 3 is fixed on the top of the derrick, including a speed governor, a safety gear 10, a buffer 11, and a terminal overrunning protection device 12. The overspeed governor is used in conjunction with the safety gear 10, etc. When the running speed of the elevator reaches or exceeds the set limit value, the overspeed governor stops and links the safety gear linkage system 13, so that the cage is stopped on the guide rail 14. Empty tensioning device 16 under the speed limiter to ensure sufficient friction between the wire rope and the speed limiter. A safety gear connecting rod 13 is provided on the top beam of the cage, a safety gear brake is provided on the bottom beam, and sliding guide shoes 15 Fixedly installed under the safety gear seat, there are four in total. The guide shoe 15 slides up and down in the derrick guide rail 14, which can prevent the cage 4 from tilting or shaking when it is running.

The spring buffer 11 is fixedly installed on the lift foundation 17, so that the suspension cage 4 or the counterweight can be buffered and decelerated when they fall. The terminal overrun protection device 12 is installed on the upper and lower terminal brackets of the guide rail 14 to prevent the hoisting cage 4 from rushing to the top or crashing into the top.
