Abstract
The utility model provides an elevator counterpoise braking device and relates to the technical field of design of construction elevator counterpoise braking devices. The elevator counterpoise braking device comprises a counterpoise, a guide rail and a braking device. Supporting plates are arranged on two sides of the counterpoise respectively, traction wheels are arranged in the supporting plates, a guiding shaft is arranged at the centers of the traction wheels, and each supporting plate is vertically provided with guiding holes which are symmetrical in the vertical direction. The braking device is arranged between the counterpoise and the guide rail and comprises a first braking push rod, a second braking push rod, an inner braking block and an outer braking block, wherein one end of the first braking push rod and one end of the second braking push rod are respectively sleeved on the guiding shaft, the other end of the first braking push rod is connected with the supporting plates through a pin shaft, a braking block guiding plate is arranged on one side, facing towards the supporting plates, of the inner braking block, and the other end of the second braking push rod is connected with the braking block guiding plate through a pin shaft. Each supporting plate is provided with a tension spring seat which is provided with a tension spring, and the other end of each tension spring is connected with the guiding shaft. The elevator counterpoise braking device can effectively prevent the counterpoise from sliding downwards timely under any conditions.
Description
Technical field
The utility model relates to the design field of vehicle for construction-building hoist counterweight brake equipment.
Background technology
On existing building hoist market, counterweight formula building hoist have an accident reason be mostly counterweight lose the constraint cause.Its reason be when haulage cable with to reconnecting when losing efficacy, basis and affiliated facility produced destroy focusing under the gravity effect free-falling body high speed impact power.
Summary of the invention
The utility model purpose be at existing counterweight formula building hoist haulage cable with to reconnecting when losing efficacy, free-falling body downslide problem at a high speed provides a kind of can the generation in counterweight steel rope moment of failure to brake under the gravity effect to focusing on, thus the Elevator weight sensor brake equipment of preventing counterweight to glide.
The utility model comprises counterweight, guide rail, brake equipment; In described counterweight both sides support plate is set respectively, in described support plate, traction wheel is set, hauling rope around the home on described traction wheel; Described traction wheel center is provided with the axis of guide, and the pilot hole of symmetry vertically is set respectively on described two support plates, and the two ends of the described axis of guide are set in respectively in the corresponding pilot hole;
Described brake equipment is arranged between counterweight and the guide rail, and described brake equipment comprises first brake push rod, second brake push rod, inside brake piece, outer slipper;
Described guide rail be equipped with the inside brake piece and outside between the slipper, described inside and outside slipper is by bolt and to reconnecting, between described inside brake piece and bolt orienting sleeve is set, between described inside brake piece and counterweight the adjustment pad is set, described adjustment pad is nested with on bolt;
One end of described first brake push rod and second brake push rod is nested with respectively at the described axis of guide and exposes on the axis body of pilot hole; The other end of described first brake push rod is connected with support plate by bearing pin; Towards a side of support plate the slipper guide plate is set at described inside brake piece, described slipper guide plate comprises the symmetrically arranged first guide plate body and the second guide plate body, and the other end of described second brake push rod is arranged between the first guide plate body and the second guide plate body by bearing pin;
Also be respectively equipped with the extension spring seat on the lateral wall of described every support plate, under pilot hole, at described extension spring seat extension spring be set, the other end of described extension spring is connected with the axis of guide.
When the utility model lost efficacy when haulage cable, brake push rod promotes slipper under action of the spring and track produces the downslide of drag friction power prevention counterweight, the utility model can under any circumstance when the tractating bar steel rope connects inefficacy, can prevent counterweight to glide timely and effectively.
