Description

a kind of rotary type falling proof device of lifting means
Technical field
The invention belongs to petroleum machinery or vertical lift elevator field, particularly relate to a kind of rotary type 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 rotary type falling proof device of lifting means, comprise draw-in groove post, suspension hook, roller, stay cord, permanent seat, adapter plate and dwang, 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, two adapter plates are separately fixed at by the two ends at the top promoting thing, described dwang is connected on adapter plate by axis of rotation, two permanent seats are arranged on the inner side of adapter plate respectively, described permanent seat is connected by spring with the upper end of dwang, described stay cord walks around two rollers and pulley, and run through fixed mount to be connected with the lower end of permanent seat by two dwangs.
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: described permanent seat top is also provided with buffering spring sheet near one end of adapter plate.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, be connected with the two ends of dwang respectively with stay cord by spring, and stay cord is suspended on the pulley of suspension hook lower end, when hoisting rope fracture, suspension hook falls, and stay cord relaxes, dwang is rotated into level under the pulling force of spring, 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.

Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation of the present invention when working.
Fig. 3 is the connection structure schematic diagram between adapter plate of the present invention, permanent seat and dwang.
Fig. 4 is adapter plate of the present invention, permanent seat and dwang work structuring schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is made a detailed explanation.
As Fig. 1, Fig. 2, the rotary type falling proof device of a kind of lifting means described in Fig. 3 and Fig. 4, comprise draw-in groove post 1, suspension hook 4, roller 6, stay cord 7, permanent seat 8, adapter plate 9 and dwang 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, two adapter plates 9 are separately fixed at by the two ends at the top promoting thing 2, described dwang 10 is rotatably connected on adapter plate 9 by rotating shaft 101, two permanent seats 8 are arranged on the inner side of adapter plate 9 respectively, described permanent seat 8 is connected by spring 11 with the upper end of dwang 10, described stay cord 7 walks around two rollers 6 and pulley, and run through fixed mount 5 to be connected with the lower end of permanent seat 8 by two dwangs 10.The upper end of described positioning plate both sides is fixed with recoil spring 401 respectively.Described permanent seat 8 top is also provided with buffering spring sheet 81 near one end of adapter plate 9.The present invention by arranging the installation site of rotating shaft and adapter plate, can make dwang and permanent seat angled, make dwang and permanent seat be "eight" shape, be more conducive to the fixing of weight.
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 is with suspension hook near fixed mount top, and stay cord pulls the lower end of dwang, and then making the upper end extension spring of dwang, dwang keeps vertical state under the effect of stay cord and spring force; When hoisting rope fracture, suspension hook falls, and stay cord relaxes, and dwang is rotated into level under the pulling force of spring, and outer end is stuck in draw-in groove post, and the inner rests on permanent seat, the fast automatic anti-lower drop function achieving weight.
