Abstract

The utility model discloses a lift working platform for maintaining building wall belonging to the equipment used in building trade. The working platform is dragged by a motor and drives a drum to rotate after the speed reduction by a worm reducer. The upper end is hung and fixed at a fixing device at the top of the building, and the lower end is coiled up and released by the steel cable coiling on the drum through a pulley wheel. So the working platform fixed with the drum can lift and fall automatically. The working platform is suitable for the wall surface treatment of the new building or the old building and is also suitable for the materials lifting in the building trade. The working height of the working platform can be adjusted to the convenient operating position of the staff optionally at any time.

Description

Lift platform for maintaining building wall

This bench board belongs to a kind of novel device that construction trade is handled newly-built building metope or aging blocks room metope, also can be used as a kind of material lifting means of construction trade.

Existing building metope work of treatment platform generally has dual mode.1. scaffolding is also placed springboard thereon as bench board.2. carry the springboard two ends with the double joint rope, the fixed pulley by the installing of exterior wall top or eaves draws down, and the bulk that fixes prior placement on the ground is given in the making sheet.The former stops after handling one section metope, moves down springboard, and removes rod on top, and the latter after handling one section metope, gets off to unclasp rope one time, makes bench board move down one section, and is fixing once more.This dual mode works together all very inconvenient, and influences work efficiency.

This bench board has overcome the shortcoming of above dual mode effectively, has reduced a lot of troubles, works together easily, and obviously increases work efficiency.

This bench board is to utilize electrical motor to do power, after worm reducer slows down, drives the reel rotation, make an end plate around and be fixed on the tube, the other end hangs fixing steel rope and coils or unclasp.Because reel and bench board fix, so coiling or unclasping of steel rope realized moving up and down of bench board, i.e. the automatic lifting of bench board.The utility model can drive a reel by worm reducer to carry out single cheese volume or unclasps the lifting of the single rope of realization.Also can drive two reels and carry out duplex type and coil or unclasp, realize the duplex type lifting.

This Working table structure is simple, operation, easy to maintenance.At any time the instrument that uses, material etc. can be placed on the bench board during work, switch on the operation element platform, bench board is risen or decline, can determine to be fit to the position that the staff works freely at any time easily, can increase work efficiency, can avoid again being not suitable for causing the uncomfortable sense of staff because of operating altitude.

Accompanying drawing 1 is the concrete structure front view of an embodiment of the utility model.

Accompanying drawing 2 is lateral plans of accompanying drawing 1.

Accompanying drawing 3 is B-B cutaway views of accompanying drawing 2.

Accompanying drawing 4 is A-A cutaway views of accompanying drawing 2.

Accompanying drawing 5 is constructionals drawing of serving compensation mechanism (15).

Accompanying drawing 6 is compensation principle figure of serving compensation mechanism (15).

Accompanying drawing 7 is E portion enlarged drawings in the accompanying drawing 1.

Below in conjunction with accompanying drawing this bench board is carried out structure and job description.

With reference to accompanying drawing 1, steel rope (2) upper end is fixed on the roof anchor fitting (1), the lower end is in directional wheel (4) is introduced bench board, and (3) are bench board work fence, and (5) are power cable.With reference to accompanying drawing 2, (7) are anti-friction the wheel.With reference to accompanying drawing 3, power supply is connected to electrical motor (8) terminal through cable (5), switch (16) (belonging to accompanying drawing 4), cable (6).Electrical motor (8) connects with worm reducer (10) through plunging joint (9), and the worm reducer output shaft is equipped with gear (11), and gear (11) drives reel (13) respectively and goes up the gear of installing (12).Steel rope (2) in the introducing bench board is worn the pulley (25) on serving compensation mechanism (15), is looped around respectively on the reel (13) by direction as shown, and is pressed on the reel with steel rope pressing plate (14).With reference to accompanying drawing 4, (16) are switch, and (17) are table surface, and (18) are the chassis.With reference to accompanying drawing 5, movable rod member (19), pulley yoke (24) connect with nut (20), thrust baring (22), the activity of coupling spindle (23) do.Pulley (25) is loaded on the pulley yoke (24) by axle (26).Movable rod member (19), permanent seat (31) connect with nut (27), thrust baring (28), the activity of coupling spindle (30) do.(21), (29) are dust protecting cap.With reference to accompanying drawing 6, when steel rope when the position is coiled to the right on the cooresponding reel of solid line pulley, because steel rope displacement to the right on the reel, steel rope on pulley produces a thrust to the right to pulley (25), make movable rod member (19) around coupling spindle (30) deflection to the right, pulley yoke (24) is with respect to movable rod member (19) deflection left, as the long and short dash line position in the accompanying drawing simultaneously.Equally, when steel rope coils, then can produce above-mentioned effect same left, realize the serving compensation.

When putting switch (16) rising or lowering position, electrical motor (8) is by cable (5), (6), switch (16) and power connection, electrical motor (8) rotation, after worm reducer (10) deceleration, drive two gears (12) rotations on the reel respectively by the gear on the output shaft (11), so the reel rotation, reel disc around or unclasp steel rope, realize the automatic lifting of bench board.
