Abstract
The utility model discloses a workover rig traveling block big hook hydraulic dismounting device suitable for the dismounting and assembly of traveling block big hook in various models in the petroleum industry. The dismounting device comprises a hydraulic telescoping cylinder, a hydraulic cylinder fluid path joint and a dismounting box body. The hydraulic telescoping cylinder is connected with the hydraulic cylinder fluid path joint, and is disposed on one side of the dismounting box body. A big hook pin taking-out hole is disposed in the other side of the dismounting box body. By using the hydraulic telescoping cylinder compression big hook spring, the dismounting and the assembly of the big hook on site can be realized. The workover rig traveling block big hook hydraulic dismounting device provided in the utility model has advantages of convenient operation, time saving, labor saving, abilities of repairing the quick dismounting and assembly of the big hook of the traveling block on the scene of the workover rig without towing the machine to the repair factory for the maintenance, reducing maintenance costs, improving working efficiency, and satisfying production requirements.
Description
Technical field
The utility model belongs to repairing facility of petroleum industry workover rig hook block, particularly workover rig hook block hydraulic dismounting device, is suitable for the dismounting and the assembling of the hook block of various models.
Background technology
The hook block of the various models that workover rig uses; Because often operation in the open air, the abominable and unfreezing and produce very big impulsive force energetically when producing corrosion or operation of environment, thus make the spring breakage in the hook hook tube; Lose damping effect, can not carry out workover treatment again.If the hook spring of disassembling, assembling and replacing fracture, the external force that needs reaches more than 10 tons.Because the pulling force that dismounting needs is bigger, and injury accident takes place as repairing at the scene in the on-the-spot demounting tool that does not have special use sometimes.General solution is to retract producer or professional repair manufacturer to on-the-spot place under repair assembling, brings many inconveniences to workover treatment.In order to address this problem, need to make workover rig hook block hydraulic dismounting device.
Summary of the invention
The purpose of the utility model provides workover rig hook block hydraulic dismounting device, makes its dismounting and assembling that just can realize hook block in the production scene, satisfies the production needs, increases work efficiency.
The technical solution of the utility model is: workover rig hook block hydraulic dismounting device comprises hydraulically extensible cylinder, hydraulic cylinder liquid pipeline connector and dismounting casing; Hydraulically extensible cylinder and hydraulic cylinder liquid pipeline connector are connected, are installed in a side of dismounting casing, are provided with the hook pin at the offside of dismounting casing and take out the hole.Use hydraulically extensible cylinder compression hook spring, realize the dismounting and the assembling of hook in the production scene.
The beneficial effect of the utility model is:
1, easy to operate, time saving and energy saving.
2, be suitable for the dismounting and the assembling of the workover rig hook block of various models.
3, can need not retract repair shop and repair at on-the-spot fast quick-detach of well workover and assembling hook block.
4, reduce the cost of repairs, improved operating efficiency, satisfied the production needs, had tangible economic benefit.
Description of drawings
Accompanying drawing is the vertical view of the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed description; Referring to accompanying drawing; Workover rig hook block hydraulic dismounting device comprises hydraulically extensible cylinder 1, hydraulic cylinder liquid pipeline connector 2 and dismounting casing 3; Hydraulically extensible cylinder 1 is connected with hydraulic cylinder liquid pipeline connector 2, is installed in a side of dismounting casing 3, is provided with the hook pin at the offside of dismounting casing 3 and takes out hole 4.The plunger front end of hydraulically extensible cylinder 1 takes out hole 4 towards the hook pin of dismounting casing 3 offsides; The hook pin takes out the external diameter of the internal diameter in hole 4 greater than the hook shank, to adapt to the use of multiple model hook shank.Hydraulic cylinder liquid pipeline connector 2 is general snap joint, and its hydraulic interface is connected with the snap joint of the hydraulic power source that workover rig carries, for the dismounting and the assembling at scene provides hydraulic power.
Dismounting casing 3 mainly is made up of steel column and thick iron plate, and its dismounting and linkage editor are following:
1, the hook block package unit is placed in the dismounting casing 3, the end of hook shank head and hydraulically extensible cylinder 1 holds out against.
2, operation hydraulically extensible cylinder 1 stretches out its plunger in dismounting casing 3, the inside and outside spring of compression hook.
3, treat that hook block shank stopper slot takes out after hole 4 exposes from the hook of dismounting casing 3 pin, two semi-circular spacing snap rings of hook are taken out from hook shank stopper slot.
4, operation hydraulically extensible cylinder 1 makes its withdrawal, and a whole set of hook shank mechanism is taken out, and accomplishes and once disassembles.
5, hook block is hung out in dismounting casing 3, change and damage spring or other accessories.
6, behind the replacing accessory, with the hook block lower spring cup, inside and outside spring and upper spring seat are enclosed within on the shank according to former order, hang in the dismounting casing 3.
7, operation hydraulically extensible cylinder 1 makes its plunger elongation, the inside and outside spring of compression hook.
8, treat that hook block shank stopper slot takes out after hole 4 exposes from the hook of dismounting casing 3 pin, two semi-circular spacing snap rings of hook are reinstalled, accomplish once assembling.
