Abstract
Disclosed is a manual releasing device of a building hoist. The building hoist comprises a hanging cage, a transmission trolley and more than one motor, wherein the motors are installed on the transmission trolley which is connected with the hanging cage through a connection rod. A brake device is placed inside each motor and comprises a pulling rod which extends out of each motor. The manual releasing device comprises an upper fixing piece group, a pipe turning group and a rod moving group, wherein the upper fixing piece group is fixed on one side of the transmission trolley, the pipe turning group is installed on the connection rod, and the rod moving group is installed inside the hanging cage. A steel wire rope is placed between and connected with the rod moving group and the pulling rod of the brake device of each motor. The steel wire rope penetrates through the pipe turning group and the upper fixing piece group in sequence. When the hanging cage is broken down, a builder can manually release brake of motor sets of the hanging cage under a safety situation, so that the accidents are reduced.
Description
Technical field
The utility model relates to building hoist, and especially construction lifter motor is in when outage, controls manually in cage that elevator drop to lower one deck or to the hand release on ground.
Background technology
High speed development along with national economy, the vehicle for constructions such as building hoist begin bringing into play huge effect at increasing building field, especially for large-engineering, skyscraper place, the use of the vehicle for constructions such as building hoist seem particularly important. because they can be boosted productivity and economize labor time greatly.Yet. along with more and more extensive, a large amount of use of vehicle for construction, contingency also is accompanied by more frequently and occurs, and the safe in operation problem also more and more receives the concern of each side.
In vehicle for construction such as building hoist, no matter be the building hoist of what type, its driving system all is to unite use (only having the design of separate unit motor fewer and feweri from the angle of safety) by the motor more than at least one (drg) usually, drives elevator craning cage and moves up and down.And vehicle for construction something unexpected happened or accident definitely can hardly be avoided in use, cause the building site to have a power failure such as the damage of building-site electrical generator, perhaps vehicle for construction generation damage of components, perhaps certain electric component has burnt out etc., all may so that the vehicle for construction cut moves, then may hang in the air such as building hoist.The manual releasing function that just need to use electromotor brake by trained professional operating personal this time so to perch or ground, such as building hoist, then needs the slow let-down of goods with the slow let-down of elevator craning cage to perch.
Domestic general vehicle for construction such as several electromotor brakes on the building hoist all are to separate individual components now, need several individuals simultaneously brake to be unclamped, perhaps brake is backed down and is fixed on release position one by one, until last brake slowly discharges decline by operating personal.Here there are several problems, first, operating personal must be climbed to motor (drg) next door and operate, if vehicle for construction is at high empty position, to be the process of a danger so, and in the position operation of high-altitude danger, must increase operator's psychological pressure, cause misoperation to occur easily; The second, operate simultaneously the release brake by several individuals, this situation at first not necessarily by chance has several operating personals through training on the scene at the contingency scene, even if having, usually also do not have enough operational spaces by the motor of vehicle for construction; The 3rd, by an operating personal will brake back down one by one fixing, there is very large potential safety hazard in this method, because at first must guarantee after process is moved for a long time, the separate unit drg still has enough lock torques can brake load, be difficult in addition guarantee that every electromotor brake does not all have fault, if by chance last electromotor brake has fault, then safety misadventure can occur.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of building hoist hand release, behind the cage et out of order, the workmen can be in the situation of safety the brake of manual release cage motor group, the minimizing accident occurs.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of building hoist hand release, described building hoist comprises cage, transmission dolly and more than one motor, described motor is installed on the described transmission dolly, described transmission dolly is connected with described cage by pipe link, be provided with drg in the described motor, described drg comprises pull bar, and described pull bar stretches out outside the motor; Described hand release comprises the upper fixing element group that is fixed on described transmission dolly one side, be installed in the tube group on the described pipe link and be installed in moving rod group in the described cage, be provided with steel rope between the pull bar of described moving rod group and the drg of described motor and be connected, described steel rope passes through described tube group and upper fixing element group successively.The utility model principle of work: when building hoist breaks down need to carry out the manual releasing cage time, in cage, move the moving rod group, moving rod rotates the pulling steel rope, steel rope after tube group turnover through the upper fixing element group, steel rope connects motor and discharges pull bar, spur domestic motor afterbody motor and discharge pull bar, motor is discharged move downward.
As improvement, be provided with the adjust bar group between fixed part group and the described tube group, the upper end of described adjust bar group is connected with steel rope, and described upper steel rope is connected with the pull bar of the drg of described motor after through the upper fixing element group; The lower end of described adjust bar group is connected with lower steel rope, and described lower steel rope is connected with moving rod group on the described cage after through the tube group.
As improvement, fixed part group comprises support and the more than one sheave of being located on the support, the corresponding motor of each sheave, described upper steel rope connects with the steel wire that is connected of one or more by the rope plate, and described connection steel wire passes through behind the sheave to be connected with the pull bar of the drg of described motor.
As improvement, described adjust bar group comprises adjust bar and is located at the adjusting ear at described adjust bar two ends that the adjusting ear at two ends is connected with upper and lower steel rope respectively.
As improvement, described tube group comprises erecting frame, is fixed on the first sheave and the second sheave on the described erecting frame, and described the first sheave and described the second sheave are at right angles arranged, and be provided with rubber tire at the place, right angle.
The beneficial effect that the utility model compared with prior art brings is:
Can discharge simultaneously the drg of multiple electric motors by control moving rod group, behind the cage et out of order, the workmen can be in the situation of safety the brake of manual release cage motor group, the minimizing accident occurs;
The adjust bar group can be regulated the degree of tightness amount of steel rope, avoids brake cable relaxation to occur because used life is long.
