Abstract

The utility model relates to the improvement on a lift structure. A guide rail frame (a head frame) which serves as a lift main body part is derated. Two guide rails of a hanging cage are installed on a wall via connecting pieces. An upper frame, a hanging beam and an anti-drop safety device which is lifted by a steel cable are arranged on buildings above the hanging cage. The hanging cage is lifted by a hoister and a hanging type safety device serves as an anti-drop safety. An integrated anti-skid traction machine with lifting and anti-drop properties can be used to serve as a driving anti-drop safety of the hanging cage. The utility model is mainly used for tall building construction.

Description

Guide rail wall-attached elevator

Relate to the improvement of building construction hoist structure

The elevator that the high building building is used divides two classes now, and a class is the steel rope driving type, and it is mainly used in loading owing to problems such as anti-break rope falls fail to solve the degree of making us relieved for a long time, and is seldom manned; Another kind of is gear, rack driven formula elevator, is the more general dual-purpose elevator of people's goods.This two classes elevator advance partly big of frame (guide rail bracket) with the material amount, account for cost than great, especially the cost of gear, tooth bar is higher.

Steel rope is the thing of ideal as transmission in the lifting lifting, and simple, the low all advantages of cost are arranged.In recent years, along with the generation of new fall arrest technology (mainly contains two kinds, it is respectively the suspension type safety, the patent No. 88217573.4 and the anti-skidding towing machine patent No. 93209895.9), made the elevator of steel rope transmission manned dual-purpose with loading, but weight, cost and installation and transportation etc. as the derrick of its shank still are unfavorable for using and popularizing, and necessity of research is arranged.

The characteristics of above mentioned two kinds of novel falling proof devices are to do the fall arrest insurance with steel rope, and this improvement for elevator structure provides essential condition.Because used the insurance of rope hoisting and fall arrest, the cage guide rail is just only born the effect of guiding, does not bear the load that traditional safety tongs glancing impact cage is given, and makes guide rail can not want derrick (guide rail bracket), and relatively freedom is installed easily.

The purpose of this utility model is to utilize the results new technology of rope hoisting and fall arrest to design a kind of guide rail dress dual-purpose building construction hoist of people's goods on the wall.

The technical solution of the utility model:

Two guide rails that cage is required are contained on the wall of building by attaching parts.Above cage, the eminence of wall is adorned one pair of upper frame, shelves beam, is used to install the lifting falling proof device of cage.Winch is contained in the side of following cage, and its steel rope is walked around to turn to down behind the pulley on the upper frame and the pulley yoke that falling proof device links to each other and linked cage.Make the safe steel rope of fall arrest insurance, by the suspension type safety, its two links cage and counterweight respectively.Cage and counterweight rise and descend along guide rail separately.

Behind high constructure knot top, with one pair of higher upper frame, make and put beam and guide rail rising, allow the baseplane height of cage reach roofing.

When the anti-skidding towing machine that uses lifting and fall arrest one is made actuating device, the falling proof device on the beam put with upper frame---suspension type safety and the downslide wheel carrier that is attached thereto are removed, the anti-skidding towing machine that changes the outfit is put on traction steel-cable, drives the quality of requirements adjustment counterweight by friction.

The beneficial effects of the utility model:

Because guide rail on the wall, without derrick (guide rail bracket), can be economized steel 3/4, has reduced cost, convenience is provided also for accumulating, installation, shown the benefit of rope hoisting and fall arrest one, for the manned universalness of elevator provides selection.

Contrast accompanying drawing 1 explanation below:

Two cage guide rails (3) of guide rail wall-attached elevator are contained on the building wall by attaching parts (1), hanging beam (7) rests on one pair of fixing upper frame (6) on the wall, falling proof device---suspension type safety (5) hangs on the beam (7), winch (1) is contained in a side of cage (8) low level, and hoisting cable (2) links cage (8) downwards after walking around the pulley of downslide wheel carrier (12).Two links the using method of the safe steel rope (4) of cage (8) and counterweight (9) by suspension type safety (5) respectively, by its inside.The guide rail (10) of counterweight (9) is two reinforcing bars that draw tension force.

Realize best way of the present utility model:

Friction-driven has safety and energy-saving advantages, and modem elevator is all used it, and therefore, the utility model preferably uses the anti-skidding towing machine (patent No. 93209895.9) of a kind of traction and fall arrest one once to see accompanying drawing 2 with the utility model accomplice application).The profile of anti-skidding towing machine is suitable for hanging.The inside has on three wheel rims has made the pulley of ratchet, and is furnished with using pawl to brake mechanism, and the action of centrifugal speed limiter control ratchet is arranged.The groove of pulley meets the standard of elevator friction-driven, and wherein a wheel is driven by motor one worm reducer, makes drive wheel usefulness, and all the other are flower wheel.The traction steel-cable that two links cage and counterweight respectively passes in the anti-skidding towing machine, walks around three wheels, to all spending greater than 180 around the angle of every wheel.When hypervelocity took place cage, centrifugal speed limiter made the using pawl to brake flower wheel, cut off the electricity supply the friction force of hoist ropes in the race cage that hovers simultaneously.Hoist ropes is actual to be four.

Contrast accompanying drawing 2 explanations below:

Two pairs of otic placodes (14) are arranged on the shell of anti-skidding towing machine (13), be used to hang over hanging beam (7), worm reducer (15) is contained in a side of shell, and two links the inside of the traction steel-cable (17) of cage (8) and counterweight (16) by towing machine respectively.Be transferred to parallel with the counterweight limit cage limit of hoist ropes (17) by an open-shelf (18) with pulley (19).

Claims

1, a kind of guide rail wall-attached elevator with the steel rope transmission, it is made up of cage, counterweight, guide rail and lifting falling proof device, feature of the present utility model is that the guide rail (3) of cage is contained on the wall of building by attaching parts (11), upper frame (6) is contained on the building, be positioned at the top of cage (8), put beam (7) on the described upper frame, the lifting falling proof device is arranged.

2, guide rail wall-attached elevator is characterized in that its lifting falling proof device is winch (1) and suspension type safety (5) according to claim 1, the hoisting cable (2) of winch (1) links cage (8) after walking around pulley on the downslide wheel carrier (1 2) that links to each other with suspension type safety (5), and the safe steel rope (4) that two links cage (8) and counterweight (9) has respectively passed through suspension type safety (5).
