Abstract

The utility model relates to a buffering and cage supporting device. The buffering and cage supporting device solves the problem that an existing anti-collision beam and an existing cage supporting device are low in strength, poor in safety, complex in structure, difficult to maintain and the like. The buffering and cage supporting device comprises an anti-collision beam and sliding chutes, wherein the anti-collision beam is fixed to a derrick, a rubber spring and cage supporting buffers are arranged at the bottom of the anti-collision beam, supports which are hinged to supporting claws are arranged in the sliding chutes respectively, each support is connected with the corresponding cage supporting buffer through a steel wire rope, and a tension spring is connected between each supporting claw and the corresponding sliding chute. The buffering and cage supporting device is exquisite in design, reasonable in structure, easy to operate and convenient to maintain, the operation that a falling cage is prevented from sliding downwards, and the operation that after the anti-collision beam is collided, and the steel wire ropes are broken, buffering and cage supporting are implemented in a step-by-step overlaying mode in the overwinding process, higher safety and higher reliability are achieved, the buffering and cage supporting device cannot be influenced by the outside world, and the buffer process can be more stable, more reliable and safer through variable-force loading.

Description

Buffer and supporting cage device

Technical field

The utility model provides a kind of hoister safety device, specifically a kind of buffer and supporting cage device.

Background technology

According to " safety regulations in coal mine " the 396th article of regulation: " within hoisting speed is greater than the elevator system of 3m/s, must establish collision prevention girders and Tank-supporting device, collision prevention girders must not double as his and use.Collision prevention girders must be able to be blocked the container and the bob-weight that after pulleying, rise; Tank-supporting device must be held clashing into the container or the counterweight that fall after collision prevention girders again, and ensures that its drop is no more than 0.5m ".But mostly there is insufficient strength, poor stability, complex structure, the problem such as difficult in maintenance in existing collision prevention girders and Tank-supporting device, the lifting of secondary vertical cage has been caused to great potential safety hazard, affects the security improvement of secondary vertical cage.

Summary of the invention

The purpose of this utility model is in order to solve above-mentioned problems of the prior art, and a kind of buffer and supporting cage device is provided.

The utility model is achieved by the following technical solution:

A kind of buffer and supporting cage device, comprises derrick, and the top of derrick is fixed with collision prevention girders, and collision prevention girders bottom centre position is provided with rubber spring, and the end positions of collision prevention girders bottom is separately installed with a holder tank energy disperser, on holder tank energy disperser, is connected with steel rope; The position being positioned on derrick under holder tank energy disperser is fixed with chute, in chute, be provided with support, the top of support and the lower end of steel rope are fixed, on support, be hinged with claw by the first bearing pin, the position that is positioned at the first bearing pin top on support is fixed with the second bearing pin, on claw, offer arc elongated slot, in the arc elongated slot of the second bearing pin holding on support on claw, support and claw can slide up and down in chute; The position that the right lower quadrant of chute is positioned at claw below is connected with extension spring, and the front bottom of the other end of extension spring and claw is fixed.

Described holder tank energy disperser belongs to existing well known device, and those skilled in the art are familiar with its Structural Tectonics and using method, asks reel, the axle bed etc. of tank energy disperser to form by 40Mn steel casting in the utility model; Inside and outside brake disc is made by 16Mn steel; Friction disc is made by the high-strength friction lining of import titanium cadmium fat base, has in the time that high-speed friction produces TRANSIENT HIGH TEMPERATURE and has very high physical stability, and braking force is accurate; Particularly two ends adopt collar bearing structure, and the speed of relative movement producing can make high speed pulleying time reduces half, thereby avoid the high temperature sintering phenomenon producing because of high speed pulleying, greatly improve the reliability of overwinding-proof.

Described claw is a subtriangular obform body, two base angle is circular-arc and offers respectively circular hole (plugging the first bearing pin) and arc elongated slot (holding the second bearing pin), there is concave arc on base, make the forward portion of claw center of gravity bias, the first bearing pin of claw bottom is fulcrum, the arc elongated slot on its top is path of motion, doing camber line around the first bearing pin rotates, when arc elongated slot on claw goes to high order end, on claw, plane is horizontal, and claw right-hand member (front end) is plane with the contact surface of lifting container above.

In the time that lifting container continues upper punch shock claw after overreach buffer, claw energy automatic retracted, just left claw by shock collision prevention girders at the bottom of lifting container continues to rise to tank time, claw is shot out under the effect of gravity and spring tension in bias, thereby holds whereabouts container.Collision prevention girders has certain elasticity, also has the buffer action of rubber spring simultaneously, can reduce impact and distortion to crossing volume container; The utility model device had both had holder tank function, had again pooling feature, the container falling is become to rigidity and accept as flexibility holder connects, the impact load to derrick and container therefore can effectively reduce to hold in the palm tank time after disconnected rope.

The beneficial effects of the utility model are:

1) design ingenious, rational in infrastructure, simple to operate, easy to maintenance;

2) disconnected rope Tank support damper substep stack enforcement after instant anti-fall pendant tank and shock collision prevention girders in pulleying process, safety and reliability;

3) device is not subject to ectocine, its variable force load make buffering course more steadily, reliable, safety.
