Technical Field
The utility model relates to an over-and-under type ground well technical field specifically is an over-and-under type ground well anti-accident device that falls.
Background
In actual production, unpredictable factors such as steel wire rope fatigue and the like often occur, the steel wire rope is accidentally broken in the using process of the lifting type ground well, and a plurality of potential safety hazards are brought to personnel and equipment. When an accident happens, the whole equipment is stopped when the free descending of the equipment does not reach the maximum impact load, so that the safety of operators and the equipment is ensured.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the above problem, a device that falls is prevented to over-and-under type ground well accident is provided, it can be when the unexpected condition takes place, when whole equipment free fall has not yet reached the biggest impact load, with equipment interception to guarantee operating personnel and equipment safety.
In order to achieve the above object, the utility model provides a following technical scheme:
a lifting type ground well accidental falling prevention device comprises an anti-falling hook arranged on an outer side upright post and a stopper arranged on an inner side upright post, wherein a steel wire rope wheel is arranged below the anti-falling hook and used for detecting the state of a steel wire rope; a tension spring is arranged between the outer side upright post and the pulley component arranged on one side of the outer side upright post, when the tension spring is stressed, the anti-falling hook inclines towards one side of the outer side upright post, and the steel wire rope pulley is stressed and positioned under the pulley component; when the tension spring is not stressed, the steel wire rope wheel moves to the right side of the pulley assembly, and the anti-falling hook slants towards one side of the inner upright post to hook the stop dog.
Further, the stopper has a specific structure that: a cylinder is vertically fixed on a square plate.
Preferably, the anti-falling hook is of an L-shaped hook structure.
Preferably, the tension spring is of a common spring structure.
The beneficial effects of the utility model reside in that:
the utility model discloses can be in case when the condition such as the wire rope fracture or take off the groove takes place, because wire rope sheave no longer atress, prevent weighing down the hook and can be under the pulling force effect of extension spring, to the slope of inside stand direction to the retainer on the stand including will installing hooks, lets equipment no longer weigh down, plays the effect of preventing weighing down, thereby guarantees operating personnel and equipment safety. The device has the advantages of simple structure, high practicability and lower maintenance cost, and only the lubricant is required to be added at the rotating shaft in a normal state, so that the device is convenient to maintain.
Drawings
In order to more clearly illustrate the technical solution of the embodiment of the present invention, the drawings required to be used in the description of the embodiment will be briefly introduced below, and obviously, the drawings in the following description are only for the purpose of more clearly illustrating the embodiment of the present invention or the technical solution in the prior art, and the drawings required to be used in the description of the embodiment or the prior art will be briefly introduced below, and for those skilled in the art, other drawings can be obtained according to the drawings without any creative effort.
FIG. 1 is a schematic view of the structure of the present invention when the force is applied;
FIG. 2 is a schematic structural view of the present invention when the force is not applied;
in the figure: 1-a tension spring, 2-a retainer, 3-an anti-falling hook, 4-a wire rope wheel, 5-an outer upright post, 6-an inner upright post and 7-a pulley component.
Detailed Description
The lifting type ground well accidental falling prevention device shown in the figure 1-2 comprises an anti-falling hook 3 arranged on an outer side upright post 5 and a stopper 2 arranged on an inner side upright post 6, wherein a steel wire rope wheel 4 is arranged below the anti-falling hook 3, and the steel wire rope wheel 4 is used for detecting the state of a steel wire rope; a tension spring 1 is arranged between the outer side upright post 5 and a pulley component 7 arranged on one side of the outer side upright post, when the tension spring 1 is stressed, the anti-falling hook 3 inclines towards one side of the outer side upright post 5, and the steel wire rope pulley 4 is stressed and positioned under the pulley component 7; when the tension spring 1 is not stressed, the steel wire rope wheel 4 moves to the right side of the pulley component 7, and the anti-falling hook 3 hooks the retainer 2 towards one side of the inner upright post 6 in an inclined mode.
Further, the stopper 2 has a specific structure that: a cylinder is vertically fixed on a square plate, as shown in figure 1.
The pulley assembly 7 is used for guiding a steel wire rope.
Preferably, the anti-falling hook 3 is of an L-shaped hook structure.
Preferably, the tension spring 1 is of a common spring structure.
The working principle is as follows:
when the lifting type ground well equipment is lifted normally, the steel wire rope wheel 4 drives the anti-falling hook 3 to overcome the tension of the tension spring 1 under the action of the gravity of the pulley component 7, and the anti-falling hook 3 is kept to incline on one side of the outer side upright post 5. Once the steel wire rope is broken or separated from the groove, the steel wire rope wheel 4 is not stressed, the anti-falling hook 3 can incline towards the inner side upright post 6 under the action of the tensile force of the tension spring 1, so that the retainer 2 arranged on the inner side upright post 6 is hooked, the equipment does not fall, and the anti-falling effect is achieved.
The utility model discloses can be when the unexpected condition takes place, when whole equipment free fall has not reached the biggest impact load yet, with equipment interception to guarantee operating personnel and equipment safety. The device has the advantages of simple structure, high practicability and lower maintenance cost, and only a lubricant needs to be added at the rotating shaft in a normal state.
The utility model discloses in over-and-under type ground well be over-and-under type ground well structure in the patent that the applicant has applied for, belong to prior art's content, this application is an accessory of addding in its structure. Other components not described in detail are known in the art.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
