Abstract
The utility model relates to an oil field well workover equipment field, open-ended coaster that moves about promptly. The steel wire rope pulley comprises a main body, wherein a pulley connected with a steel wire rope is arranged on the main body, a hook body is arranged at the lower end of the main body, the steel wire rope pulley is characterized in that the pulley is surrounded by a plurality of groups around the main body, a cavity is arranged in the middle of the main body, an opening for oil supply pipes to pass through is arranged at the upper part of the main body, a cylinder is embedded in the lower part of the main body and communicated with the cavity of the main body, a hollow hole. The oil pipe can freely shuttle and retract in the middle of the hook body, the elevator is dismounted at the upper part, the elevator is not required to be dismounted after the hook is hooked, the number of personnel of the traditional workover rig can be reduced, the working efficiency is increased, and the manufacturing cost and the using and maintaining cost are both reduced.
Description
Technical Field
The utility model relates to an oil field well workover equipment field, open-ended coaster that moves about promptly.
Background
In the prior art, a traveling block hook (or called a traveling block) of the existing workover rig drives a lifting ring elevator to draw out an oil rod or an oil pipe, then the oil rod or the oil pipe falls down, an operator unlocks the lifting ring elevator below to place the oil pipe on a platform, the operation flow is long in time, the working efficiency is low, and manpower is wasted because the operator needs to continuously move the oil pipe back and forth. The conventional YG90-0 hook can be operated once per round trip, and 2-3 persons are required to detach the tubing elevator under the platform, resulting in waste of personnel and low work efficiency. How to design one kind can make oil pipe freely shuttle in the hook, can accomplish well workover and can improve work efficiency again, reduce the manpower, reduce intensity of labour and become the market demand.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing an open type traveling block aiming at the defects. The oil pipe can freely shuttle and retract in the middle of the hook body, the elevator is dismounted at the upper part, the elevator is not required to be dismounted after the hook is hooked, the number of personnel of the traditional workover rig can be reduced, and the working efficiency is improved.
The technical solution of the utility model is that: the open type traveling block comprises a main body, wherein pulleys connected with a steel wire rope are arranged on the main body, and a hook body is arranged at the lower end of the main body.
In the above scheme, the cylinder is provided with a positioning pin. The pulleys are in three groups.
The utility model has the advantages that: the oil pipe can freely shuttle and retract in the middle of the hook body, the elevator is dismounted at the upper part, the elevator is not required to be dismounted after the hook is hooked, the number of personnel of the traditional workover rig can be reduced, the working efficiency is increased, and the manufacturing cost and the using and maintaining cost are both reduced.
Embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

Fig. 1 is a schematic view of the structure of the present invention.
Detailed Description
Referring to fig. 1, the part names are as follows: pulley 1, main part 2, drum 3, rings elevator 4, boss 5, locating pin 6, lug 7.
Referring to fig. 1, the open type traveling block comprises a main body 2, a pulley 1 connected with a steel wire rope is arranged on the main body 2, and a hook body is arranged at the lower end of the main body 2. The pulley 1 is surrounded by three groups around the body 2, in a U-shape with an open middle. The middle of the main body 2 is a cavity, the upper part of the main body is provided with an opening through which an oil supply pipe passes, the cylinder 3 is embedded in the inner lower part of the main body 2 and is communicated with the cavity of the main body 2, the middle of the cylinder 3 is a hollow hole through which the oil supply pipe passes up and down, and the lower part of the cylinder 3 is connected with a lifting lug. The upper end of the cylinder 3 is provided with a boss 5 so that the cylinder 3 is embedded in the main body 2, and the cylinder 3 is provided with a positioning pin. The positioning pin 6 on the cylinder 3 is fixed, the positioning pin 6 is pulled out to finely adjust the cylinder 3 due to different possible positions of different operation habits in the wellhead, a lifting lug 7 exists on the cylinder 3, the lifting ring elevator 4 is hung on the lifting lug 7, the other end of the lifting ring is hung on the elevator, the lifting ring elevator 4 of the device can be selected according to requirements in work, under the action of the lifting ring elevator 4, the well repairing oil pipe can freely shuttle in the hook body, and therefore well repairing operation can be completed. The oil pipe is placed vertically. The workers work on the racking platform and the oil pipe rack is vertically arranged, so that the number of the workers of the traditional workover rig can be reduced, the efficiency of the traditional workover rig is increased by about 40 percent, and the overall structure is simpler than that of a YG90-0 hook.
The above description is only exemplary of the present invention, and the various illustrations do not limit the essence of the present invention.
