Description
Technical field
The invention belongs to petroleum machinery or vertical lift elevator field, particularly relate to a kind of Pop-up falling proof device of lifting means.
Background technology
At present, at oil exploration equipment, particularly there is the oil pumper of counterweight perpendicular movement, and have in the lifting means such as car vertical lift elevator all need use halliard (steel rope or steel band) lift weight (counterweight or car), halliard due to castering action is consumable accessory, the actions such as the bending winding of long-term repetition easily cause breaking, even rupture, need counterweight or car to be fixed on a certain position when overhauling simultaneously, in pumping equipment prior art, conventional processing mode has: use supporter to be held up by weight, what use stock bolt-type is stuck on equipment by weight, although solve falling risk to a certain extent, but can not remove voluntarily, need manually to carry out dismounting supporter or stock.
In elevator, normal use safety pincers are in emergency circumstances braked, and often certain physical injury is caused to cage guide and lift car when safety tongs action, therefore all by the action of safety tongs, lift car can not be fixed on a certain position in each maintenance.Bolt-type falling proof device at the degree of freedom of vertical direction, makes it maintain vacant state by latch restriction car.But latch degree of freedom in the horizontal direction is not restricted, still stable not under causing it in working order, once latch skids off from lockhole, will major accident be there is.
Summary of the invention
In order to solve above-mentioned technical matters, the object of this invention is to provide a kind of rotary type falling proof device of lifting means, this device can fix rapidly weight (counterweight or car) when " halliard " fracture occurs, and avoids generation weight to fall and causes casualties and property damage.
In order to realize above-mentioned object, present invention employs following technical scheme:
A kind of Pop-up falling proof device of lifting means, comprise draw-in groove post, suspension hook, roller, stay cord and latch fixed block, described draw-in groove post is fixed on by the fluctuating orbit of the both sides of lifting thing, the described center of top by lifting thing is fixed with fixed mount, described suspension hook runs through fixed mount top, and the upper end of suspension hook is connected with hoisting rope, the lower end of suspension hook is fixed with pulley, the upper end of described suspension hook top sheave is also provided with positioning plate, two rollers are fixed on by the top promoting thing by spacer support frame, and two rollers are all positioned at fixed mount inside, the described two ends by lifting thing top are fixed with permanent seat respectively, the opening of permanent seat is towards draw-in groove post, described latch fixed block is arranged in permanent seat, and latch fixed block and permanent seat are provided with spring between a sidewall of fixed mount, described stay cord walks around two rollers and pulley, and run through fixed mount, two latch fixed blocks are connected with spring by permanent seat.
Preferably: the upper end of described positioning plate both sides is fixed with recoil spring respectively.When weight or miscellaneous part are suddenly to hoisting rope application force, effectively cushioned by recoil spring between positioning plate and fixed mount, avoid disconnected rope phenomenon to occur as much as possible.
Preferably: the two ends up and down of described permanent seat opening part inwall are also provided with buffering spring sheet.Buffering spring sheet can alleviate the impulsive force of dwang to permanent seat, extends the service life of permanent seat.
The present invention is owing to have employed above technical scheme, latch fixed block pressuring spring is made by the stay cord be suspended on suspension hook lower end pulleys, make latch fixed block submerge in permanent seat, do not affect the normal use of lifting means, when hoisting rope fracture, suspension hook falls, stay cord relaxes, and latch fixed block is protruding under spring force, and outer end is stuck in draw-in groove post, the inner rests on permanent seat, the fast automatic anti-lower drop function achieving weight.The present invention's existing weight tenesmus pooling feature, also have heavy lift pooling feature, at utmost ensure safety, and this structure is simply effective, cost is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation of the present invention when working.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is made a detailed explanation.
The Pop-up falling proof device of a kind of lifting means as depicted in figs. 1 and 2, comprise draw-in groove post 1, suspension hook 4, roller 7, stay cord 8 and latch fixed block 10, described draw-in groove post 1 is fixed on by the fluctuating orbit of the both sides of lifting thing 2, the described center of top by lifting thing 2 is fixed with fixed mount 5, described suspension hook 4 runs through fixed mount 5 top, and the upper end of suspension hook 4 is connected with hoisting rope 3, the lower end of suspension hook 4 is fixed with pulley, the upper end of described suspension hook 4 top sheave is also provided with positioning plate, two rollers 7 are fixed on by the top promoting thing 2 by spacer support frame, and two rollers 7 are all positioned at fixed mount 5 inside, the described two ends by lifting thing 2 top are fixed with permanent seat 9 respectively, the opening of permanent seat 9 is towards draw-in groove post 1, described latch fixed block 10 is arranged in permanent seat 9, and latch fixed block 10 and permanent seat 9 are provided with spring 11 between a sidewall of fixed mount 5, described stay cord 8 walks around two rollers 7 and pulley, and run through fixed mount 5, two latch fixed blocks 10 are connected and are suspended on suspension hook 4 by permanent seat 9 and spring 11.The upper end of described positioning plate both sides is fixed with recoil spring 6 respectively.The two ends up and down of described permanent seat 9 opening part inwall are also provided with buffering spring sheet 12.
Principle of work of the present invention is as follows, when lifting means normally works, hoisting rope pulls suspension hook, suspension hook and fixed mount interact to drive and are promoted thing and be elevated, simultaneously because stay cord is suspended on the pulley of suspension hook lower end, stay cord with suspension hook near fixed mount top, stay cord pulls latch fixed block, and extrusion spring makes spring-compressed, when hoisting rope fracture, suspension hook falls, stay cord relaxes, and latch fixed block is protruding under spring force, and outer end is stuck in draw-in groove post, the inner rests on permanent seat, the fast automatic anti-lower drop function achieving weight.
