Abstract
The invention relates to hoisting equipment capable of preventing mechanical damages. The hoisting equipment comprises an ejection plate, a hoisting beam, lifting lugs, a first long pull rod and a second long pull rod, wherein the lower end of the first long pull rod is rotationally connected with the left end of the hoisting beam and the upper end of the first long pull rod is rotationally connected with the ejection plate; the lower end of the second long pull rod is rotationally connected with the right end of the hoisting beam and the upper end of the second long pull rod is rotationally connected with the ejection plate; a kidney-shaped plate which is horizontally arranged is arranged in the middle of the ejection plate; symmetrically-arranged connecting holes are formed in the two sides of the kidney-shaped plate; connecting lug seats are arranged on the surfaces of the upper middle sections, which are far away from the hoisting beam, of one sides of the first long pull rod and the second long pull rod; and resetting springs are arranged between the connecting holes in the kidney-shaped plate and the connecting lug seats. The hoisting equipment capable of preventing the mechanical damages is simple in structure and reasonable in design; when heavy objects under the hoisting beam are not balanced, the ejection plate swings; and the hoisting beam and the heavy objects can rapidly return to be static and the heavy objects are prevented from swinging severely, so that the damages on the hoisting equipment can be reduced.
Description
Technical field
The present invention relates to mechanical field, relate in particular to a kind of hanging device of anti-mechanical damage.
Background technology
In prior art, there is a kind of lifting appliance, comprise top board, two group leader's pull bars, hoisting beam, hanger, long draw one end connects hoisting beam, one end is top board fixedly, thereby make top board, between two group leader's pull bars and hoisting beam, form the tripod structure of a stable mechanical property, and one or more hangers are connected hoisting beam by hawser, this kind of structure worked as engine installation and pulled top board, thereby during the weight that lifting is fixed by hanger, as there is overbalance, more easily to top board, two group leader's pull bars, connecting portion between hoisting beam causes mechanical damage, affect service life of equipment, the hanging device of a kind of anti-mechanical damage of announcing according to number of patent application 201210433891.0, wherein long draw a mono-side is rotationally connected described hoisting beam left end, opposite side is rotationally connected described top board, long draw b mono-side is rotationally connected described hoisting beam right-hand member, opposite side is rotationally connected described top board, adopt and be rotationally connected and can reduce mechanical damage by actv. like this, but there is a problem in such mechanism, when hoisting beam below hangs weight overbalance, if there is the swing of certain angle in top board now, such structure just easily makes weight swing by a relatively large margin occur and be difficult for replying static, so also easily cause the damage of this derricking gear.Therefore,, for addressing the above problem, spy provides a kind of new technical scheme.
Summary of the invention
The object of the invention is, in order to overcome the deficiencies in the prior art, provides a kind of hanging device of anti-mechanical damage.
The present invention is achieved through the following technical solutions:
A kind of hanging device of anti-mechanical damage, comprise top board, hoisting beam, hanger, described top board lower end is provided with the first long draw and the second long draw being arranged symmetrically with, described the first long draw lower end is rotationally connected described hoisting beam left end, upper end is rotationally connected described top board, described the second long draw lower end is rotationally connected described hoisting beam right-hand member, upper end is rotationally connected described top board, the middle part of described top board is provided with the kidney-shaped plate of horizontal arrangement, the both sides of described kidney-shaped plate are provided with the connecting bore being arranged symmetrically with, on described the first long draw and the second long draw, away from upper section surface in hoisting beam one side, be provided with engaging lug seat, on described kidney-shaped plate, between connecting bore and engaging lug seat, be provided with returning spring.
As preferably, described kidney-shaped plate is positioned at the upside of the junction of the first long draw, the second long draw and top board.
As preferably, between described kidney-shaped plate and top board, be welded to connect.
As preferably, between described engaging lug seat and the first long draw, the second long draw, be welded to connect.
Compared with prior art, the invention has the beneficial effects as follows: the present invention is simple in structure, reasonable in design, during weight overbalance under hoisting beam, top board swings, the Quick-return that the present invention can realize hoisting beam and weight is static, avoids weight that swing by a relatively large margin occurs, and this also just can reduce the damage to this derricking gear.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1. top board; 2. the first long draw; 3. the second long draw; 4. hoisting beam; 5. hanger; 6. kidney-shaped plate; 7. connecting bore; 8. engaging lug seat; 9. returning spring.
The specific embodiment
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Refer to Fig. 1, a kind of hanging device of anti-mechanical damage, comprise top board 1, hoisting beam 4, hanger 5, described top board 1 lower end is provided with the first long draw 2 and the second long draw 3 being arranged symmetrically with, described the first long draw 2 lower ends are rotationally connected described hoisting beam 4 left ends, upper end is rotationally connected described top board 1, described the second long draw 3 lower ends are rotationally connected described hoisting beam 4 right-hand members, upper end is rotationally connected described top board 1, the middle part of described top board 1 is provided with the kidney-shaped plate 6 of horizontal arrangement, described kidney-shaped plate 6 is positioned at the first long draw 2, the upside of the junction of the second long draw 3 and top board 1, and be welded to connect between described kidney-shaped plate 6 and top board 1.The both sides of described kidney-shaped plate 6 are provided with the connecting bore 7 being arranged symmetrically with, on described the first long draw 2 and the second long draw 3, away from upper section surface in hoisting beam 4 one sides, be provided with engaging lug seat 8, between described engaging lug seat 8 and the first long draw 2, the second long draw 3, be welded to connect.On described kidney-shaped plate 6, between connecting bore 7 and engaging lug seat 8, be provided with returning spring 9.During weight overbalance under hoisting beam 4, top board 1 swings, and by returning spring 9, carries out left and right balance, can realize hoisting beam 4 static with the Quick-return of weight, avoid weight that swing by a relatively large margin occurs, this also just can reduce the damage to this derricking gear.
