The derrick racking platform tubing string safe self-lock hook has the advantages that the derrick racking platform tubing string safe self-lock hook can be freely locked and unlocked, thereby enabling a turning string not to break away from the control range of workers. Even though the workers misoperate, the derrick racking platform tubing string safe self-lock hook can play the role of secondary protection, thereby achieving the highest safety protection performance. The derrick racking platform tubing string safe self-lock hook is convenient and simple to operate and use, light in quality and convenient to carry, is simple in process on the other side and low in material cost, does not pollute environment, and is obvious in energy-saving consumption reduction.
Description
Technical field
The utility model relates to a kind of safety platform tubing string safe self-locking hook, belongs to the workover eration technical field.
Background technique
When workover eration, tubing string and hook need be caught in the operating range of moving self to the card of being holded funeral rites, pendulum comb post with easy hook during rigger's operation of safety platform, because too much easily causing, tubing string wax deposition or parcel dead oil hook de-tubing string, de-tubing string easily appears hooking in another side personnel misoperation, cause tubing string to be toppled over and injure equipment and personnel by a crashing object, adding that simple and easy hook means of fixation is improper, easily cause falling object from high altitude, cause great potential safety hazard and equipment damage.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of safety platform tubing string safe self-locking hook.
A kind of safety platform tubing string safe self-locking hook, hook body has first connecting rod spacing hole, the second spacing hole, driving lever is fixed on the first connecting rod spacing hole by pin, chain link one end is connected with driving lever, and the chain link the other end is connected with connecting rod, and connecting rod is fixed on the second spacing hole of hook by pin, one end of spacing tightrope is connected with connecting rod, the other end of spacing tightrope is connected with the tail rope ring, and the tail rope boxing connects and is fixed on hook bottom, and spring is connected with hook with connecting rod.
The utility model has the advantages that and can freely lock and release, tubing string can not broken away from staff's control range.Even if personnel's misoperation, latch nook can play the second protection effect, makes security protection reach the highest.Easy for operation simple, quality is light, is easy to carry, and the another side processing technology is simple, and the cost of material is low, can not produce environmental pollution, obviously energy-saving and cost-reducing.
The accompanying drawing explanation
When considered in conjunction with the accompanying drawings, by the detailed description with reference to following, can more completely understand better the utility model and easily learn wherein many advantages of following, but accompanying drawing described herein is used to provide further understanding of the present utility model, form a part of the present utility model, schematic description and description of the present utility model, for explaining the utility model, does not form improper restriction of the present utility model, as schemed wherein:
Fig. 1 is structural representation of the present utility model.
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Embodiment
Obviously, the many modifications and variations that those skilled in the art do based on aim of the present utility model belong to protection domain of the present utility model.
Embodiment 1:
As shown in Figure 1, a kind of safety platform tubing string safe self-locking hook, hook 1 body has first connecting rod spacing hole 9, the second spacing hole 8, driving lever 2 is fixed on first connecting rod spacing hole 9 by pin, chain link 3 one ends are connected with driving lever 2, chain link 3 the other ends are connected with connecting rod 4, connecting rod 4 is fixed on the second spacing hole 8 of hook 1 by pin, one end of spacing tightrope 6 is connected with connecting rod 4, the other end of spacing tightrope 6 is connected with tail rope ring 7, tail rope ring 7 is weldingly fixed on hook 1 bottom, and spring 5 is connected with hook 1 with connecting rod 4.
After tubing string and driving lever 1 collision, cause it to move to maximum lengthwise position, driving lever 1 drives chain link 3 and connecting rod 4 moves simultaneously, and Compress Spring 5 generations are to the spring-back force of driving lever 1, when tubing string does not contact with driving lever 1, spring-back force drive link 4, chain link 3, driving lever 1 self-return that spring 5 produces reach self-locking.
Coupler body itself forms with spring link mechanism the spacing of holding, the connecting rod Compress Spring drives the semi-circle orbiting motion that chain link is done several angle, chain link drives the circular motion that driving lever is done several angle, the coupler body mouth of hook and driving lever have fixing extended distance realize the tubing string self-locking and freely pass through, the radius of coupler body own and driving lever longitudinal pitch have two tubing coupling distances, more conveniently realize that driving lever when motion and oil pipe do not produce on track and interfere.Spacing tightrope is connected with connecting rod end to be used for fixing holds spacing, and the tail rope ring is to be connected and fixed on safety platform and to prevent that falling object from high altitude and tubing string from toppling over out of controlly by tightrope, plays the safety protection effect.
As mentioned above, embodiment of the present utility model is explained, but, as long as not breaking away from fact inventive point of the present utility model and effect can have a lot of distortion, this will be readily apparent to persons skilled in the art.Therefore, within such variation also all is included in protection domain of the present utility model.
