Abstract
The utility model relates to a safety protector for coal mines, specifically an anti-fall device of a change gondola, which solves the problem of hidden danger caused by that the existing change gondola can fall off and injure people. The anti-fall of a change gondola comprises a base, wherein the lower part of the base is connected with two brackets, a ratchet ring is arranged at the inner side of one bracket, a hoisting drum is arranged between the two brackets, a ratchet claw plate is arranged at one side of the hoisting drum near the ratchet ring, a ratchet claw is arranged on the ratchet claw plate, a rolling-back spring is arranged between the other end of the hoisting drum and the brackets, and protection wires are wrapped on the hoisting drum. The utility model uses the design of the ratchet ring as a braking ratchet set, the hoisting drum and the rolling-back spring, prevents the gondola from falling when the ropes of the gondola break off, guarantees safety of workers, has simple maintenance and practical and reliable use, effectively avoids injury caused by the falling of the gondola, eliminates the hidden danger, and increases economic benefit.
Description
Technical field
The utility model relates to a kind of colliery safety guard, is specially a kind of hanging basket anti-fall device of changing one's clothes.
Background technology
At present, great variety has generally taken place in the service conditions of coal miner, and the advanced electronic hanging basket of changing one's clothes of false roof formula has replaced traditional wooden or iron locker, for coal miner provides the more comfortable condition of changing one's clothes.Driven hanging basket is used as power with motor, and nylon rope is made hauling rope, and it is risen to apart from ground about 4 meters, and collective forms pseudo-top ceiling at the bottom of the hanging basket of changing one's clothes, and is both artistic and practical.But also brought a potential safety hazard, in case be exactly that the nylon hauling rope is because of aging fatigue or serious wear, all can cause when perhaps upper limit travel switch lost efficacy and hang blue hauling rope fracture, cause the hanging basket of heavily about 25-35 kilogram to fall, damage hanging basket even injure following pedestrian or staff by a crashing object, bring adverse effect to safety and production.
Summary of the invention
The utility model exists and may fall the security hidden trouble of hurting sb.'s feelings and a kind of hanging basket anti-fall device of changing one's clothes is provided in order to solve the existing hanging basket of changing one's clothes that exists.
The utility model is realized by following technical scheme, a kind of hanging basket anti-fall device of changing one's clothes, comprise base, be connected with two supports under the base, one of them support inboard is provided with the ratchet circle that inner ring has tooth bar, be provided with drum shaft between two supports, be with the elevator cylinder on the drum shaft, one side of the contiguous ratchet circle of elevator cylinder is provided with pawl disk, and pawl disk is provided with ratchet, and an end of ratchet and pawl disk flexibly connect, the middle part of ratchet also is connected with compression spring, the compression spring other end is connected on the pawl disk, is provided with the backrush spring between the elevator cylinder other end and the support, is tied with on the elevator cylinder and protects rope.
The utility model is reasonable in design, adopted the design of the braking of ratchet circle wheels, elevator cylinder and backrush spring, can make to utilize behind the hanging basket fracture of rope and hang blue weight and ratchet circle braking wheels are started working rapidly and prevent to hang indigo plant and fall, ensured workman's safety, easy for installation, safeguard simple, practical reliable, can effectively avoid the fall generation of casualty accident of hanging basket, eliminate potential safety hazard, improve economic benefit.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Fig. 2 is the right elevation of Fig. 1
Among the figure: 1-base, 2-ratchet circle, 3-support, 4-ratchet, 5-drum shaft, 6-elevator cylinder,
7-pawl disk, 8-compression spring, 9-protect rope, 10-support, 11-backrush spring
The specific embodiment
As schematically shown in Figure 1, a kind of hanging basket anti-fall device of changing one's clothes, comprise base 1, base is connected with two supports 3 for 1 time, 10, one of them support 3 inboard is provided with the ratchet circle 2 that inner ring has tooth bar, two supports 3, be provided with drum shaft 5 between 10, be with elevator cylinder 6 on the drum shaft 5, a side of elevator cylinder 6 contiguous ratchet circles 2 is provided with pawl disk 7, as schematically shown in Figure 2, pawl disk 7 is provided with ratchet 4, one end of ratchet 4 and pawl disk 7 flexibly connect, and the middle part of ratchet 4 also is connected with compression spring 8, and compression spring 8 other ends are connected on the pawl disk 7, be provided with backrush spring 11 between elevator cylinder 6 other ends and the support 10, be tied with on the elevator cylinder 6 and protect rope 9.
Under normal circumstances, the staff operates the hanging basket of changing one's clothes, and its operation is at the uniform velocity to rise or descend.When hanging basket descended, elevator cylinder 6 turned round by protecting 9 elastic force that overcome backrush spring 11 under the action of gravity traction of hanging basket of restricting; When otherwise hanging basket rose, backrush spring 11 overcame the gravity that protects rope 9 and rope is protected in backrush; This moment, pawl disk 7 rotations were slower, the centnifugal force of its generation is less than the elastic force of the compression spring 8 of ratchet 4, and therefore ratchet 4 can or not touch the tooth bar on the brake ratchet circle 2 because of centrifugal effect moves yet, so, anti-fall device normal operation and do not produce braking.
When or upper limit travel switch inefficacy badly damaged owing to the hanging basket hauling rope cause the hauling rope fracture, hanging basket will be done the movement of falling object, descending speed can increase suddenly, and the pressure that the bigger centnifugal force that produces because of the rotation of pawl disk 7 flat-out accelerations makes ratchet 4 overcome compression spring 8 is outwards done centrifugal swing, touch mutually with tooth bar on brake ratchet circle 2 inboards outer end of ratchet 4, force 6 stalls of elevator cylinder to carry out braking, protecting rope 9 replaces hauling rope that the hanging basket traction is lived immediately, prevent hanging basket damage or fall and hurt sb.'s feelings, thereby realize the purpose of safe operation.After disconnected rope fault takes place, change and handle by staff's rope that will break, after reconnecting.Operate the hanging basket master cock again hanging basket is risen several centimetres in advance, the elastic force of the pressured spring that contracts of braking ratchet automatically resets, and breaks away from the interior sawtooth of brake ratchet circle.Just can move by the normal running hanging basket then.
