Abstract
The utility model discloses an elevator guide-shoe-type brake. The elevator guide-shoe-type brake is arranged on a car frame of an elevator, and comprises two electromagnets, wherein the power control of the two electromagnets is performed by a control system of the elevator; the two electromagnets are arranged in parallel; two brake arms which are arranged in parallel are arranged between the two electromagnets; the two brake arms are connected through a spring and are drawn inwards by the spring; each brake arm is connected with a replaceable brake piece; and a replaceable guide rail is clamped between the brake pieces. The elevator guide-shoe-type brake provided by the utility model, the brake of the elevator is realized in a hybrid braking mode of safety tongs and conventional drum brake, not only a general conventional drum brake function can be realized, but also part functions of the safety tongs can be realized; moreover, hidden dangers of abrupt stop and car slipping happed when a traction wheel rope groove is abraded can be eased greatly; and the service life of the traction wheel is prolonged.
Description
Technical field
The relevant a kind of elevator cage brake equipment of the utility model is meant especially and a kind ofly can brakes and can reduce and stop to slip the elevator guide shoe formula band-type brake of car hidden danger incidence because of the wearing and tearing of traction sheave grooving are afterwards anxious elevator.
Background technology
At present, elevator traction machine brake sticking brake active position on the brake wheel surface of traction sheave concentric, generally, after the band-type brake on the towing machine is held brake wheel tightly; The static friction force of traction sheave grooving and traction steel-cable has determined the braking force of car, through long-term use, after the wearing and tearing of traction sheave grooving; This static friction force descends, and has therefore increased the possibility of slide car, causes potential safety hazard; Be that traction sheave stops operating, and steel rope slides in grooving, cause car out of control mobile.
The utility model content
In view of this, the main purpose of the utility model is to provide a kind of and can brakes and can reduce and stop to slip the elevator guide shoe formula band-type brake of car incidence because of traction sheave grooving wearing and tearing back is anxious elevator.
For achieving the above object, the utility model provides a kind of elevator guide shoe formula band-type brake, and it is installed on the sedan-chair frame of elevator; Said elevator guide shoe formula band-type brake includes two electromagnets of being switched on and being controlled by the control system of elevator; These two electromagnets laterally arrange, and are provided with two lock arms that laterally arrange in the middle of these two electromagnets, and two said lock arms are by the spring connection and by the said lock arm of the inside tractive of this spring; Be connected with brake lining on each said lock arm, clamping has guide rail between the said brake lining.
The elevator guide shoe formula band-type brake of the utility model can play the function of general " traditional drum-type band-type brake "; Also can realize the partial function of " safety tongs "; Realization is braked elevator; And can greatly alleviate and stop to slip the generation of car hidden danger because of traction sheave grooving wearing and tearing back is anxious, prolong the service life of traction sheave.Be convenient for changing for frequent parking worn-down position, need not tear towing machine open, need not cut off the power supply fully, as long as change a bit of guide rail and brake lining.
Description of drawings
Fig. 1 is the structural representation of the utility model elevator guide shoe formula band-type brake;
Fig. 2 is the constructional drawing of another angle of the utility model elevator guide shoe formula band-type brake, the i.e. elevational schematic view of Fig. 1.
The specific embodiment
For ease of structure of the utility model and the effect that reaches are had further understanding, existing conjunction with figs. develops simultaneously the preferred embodiment detailed description as follows.
Every elevator car frame generally should symmetry be installed two or four elevator guide shoe formula band-type brakes, because of principle of work is identical, below is that example describes with an elevator guide shoe formula band-type brake all.
Like Fig. 1 and shown in Figure 2; The utility model elevator guide shoe formula band-type brake, it is installed on the elevator car frame, and it includes two electromagnets that laterally arrange 1; Be provided with two lock arms 2 that laterally arrange in the middle of two electromagnets 1; Lock arm 2 is connected by spring 3 and by spring 3 inside tractive lock arms 2, is connected with brake lining 20 on each lock arm 2, and clamping has guide rail 4 between the brake lining 20.Under the elastic force effect of spring 3, brake lining 20 clamps guide rail 4, and therefore elevator car frame can be braked on certain section guide pass.When electromagnet 1 energising work; Because electricity produces magnetic; Magnetic action is in lock arm 2; Lock arm 2 drives brake lining 20 and under magnetic action, moves to both sides, makes brake lining 20 getaways 4, and elevator car frame just can move (moving like the vertical direction of elevator car frame among Fig. 1 along guide rail 4) along the extension direction of guide rail 4.The coil break-make of apparatus for controlling elevator control electromagnet 1 realizes to leading the control of boots formula band-type brake, to realize the braking to elevator.Brake lining 20 in the utility model can be changed with guide rail 4, to avoid undue wear.
The boots formula of the leading band-type brake of the utility model can play the function of " safety tongs " to a certain extent, and elevator car frame is stopped on the guide rail, and the utility model is led boots formula band-type brake can be as " safety tongs " " padding machine ", and the trouble that resets.Leading boots formula band-type brake can bidirectional protective, and no matter the sedan-chair frame upwards goes still to go downwards can be played the effect of braking elevator.
Lead the function that boots formula band-type brake can also play " wire holder " to a certain extent, after elevator stops, braking force is transferred on the guide rail, can play the effect of minimizing equally the damage of towing machine transmission shaft lever.
The boots formula of the leading band-type brake of the utility model can replace towing machine " traditional drum-type band-type brake " fully or share the burden of band-type brake on the towing machine; Improve the safety of elevator; Boots formula band-type brake is led in utilization; Can greatly alleviate and stop to slip the generation of car hidden danger because of traction sheave grooving wearing and tearing back is anxious, prolong the service life of traction sheave.
The boots formula of the leading band-type brake controllable logic sequential of the utility model is identical with the logical sequence of original towing machine band-type brake, and the control system of elevator does not need the program change to control.Because leading boots formula band-type brake is relatively independent parts, also can control separately, mode is flexible.
The above is merely the preferred embodiment of the utility model, is not the protection domain that is used to limit the utility model.
