Description

Technical Field

[0001] The utility model relates to a workover rig derrick inclination fine-tuning device, belonging to the technical field of workover rig accessory equipment. Background Art

[0002] The derrick is a commonly used device in the well repair rig to assist in replacing the oil pipe and the sucker rod. The operating wellhead size is adjusted by adjusting the derrick inclination angle, and the safety and stability during operation are ensured by fixing and locking the lower body of the derrick with the derrick base. Most of the well repair rigs on the market, such as the automatic environmentally friendly integrated operating machine disclosed in the utility model patent with the authorization announcement number CN208830946U, can meet the needs of use to a certain extent, but their inclination angles are designed and calculated to be achieved through the telescopic cylinders of the upper and lower bodies of the derrick. When the inclination angle needs to be adjusted, it is done by adjusting the frame chassis with a jack. However, the frame chassis is the supporting foundation of the entire equipment. When adjusting it, there are not only problems of high energy consumption but also high risks. Therefore, it is necessary to develop a new inclination fine-tuning device to solve the above problems of existing well repair rigs. Summary of the invention

DETAILED DESCRIPTION

[0022] The workover rig derrick inclination fine-tuning device comprises a base 1, a lower derrick 3, a support plate 4, a mechanical jack 5, a clamping seat 6 and a locking rod 7 (see the attached manual). Figure 1 and 2 ).

[0023] The base 1 is hingedly connected to a lower body derrick 3 through a transfer shaft 2; a support plate 4 is fixedly installed at the lower end of one side of the lower body derrick 3; a mechanical jack 5 is fixedly installed at the lower end of the support plate 4; one side of the mechanical jack 5 is connected to the support plate 4 through a reinforcing plate 9 (see the attached manual). Figure 2 ).

[0024] The mechanical jack 5 includes a limiting nut 13, an outer sleeve 10, an inner core shaft 11 and an extrusion head 12; the outer sleeve 10 is fixedly mounted on the lower end of the support plate 4; the inner core shaft 11 is connected to the inner thread of the outer sleeve 10; the lower end of the inner core shaft 11 is extended to the outside of the outer sleeve 10 and then provided with an extrusion head 12; the extrusion head 12 is provided with a control hole 14. The limiting nut 13 is threadedly connected to the inner core shaft 11 below the outer sleeve 10 (see the attached manual). Figure 3 ).

[0025] During operation, the inner core shaft 11 can be rotated by inserting the operating rod into the control hole 14, so as to achieve the purpose of extending or retracting the inner core shaft 11. The purpose of providing the limiting nut 13 is that after the inner core shaft 11 is adjusted, the inner core shaft 11 and the outer sleeve 10 can be kept fixedly connected by tightening the limiting nut 13.

[0026] A clamping seat 6 is installed on one side of the mechanical jack 5 (see the attached manual). Figure 2 The clamping seat 6 includes a clamping panel 15 and a supporting plate 16; the clamping panel 15 is fixedly mounted on one side of the outer sleeve 10; two groups of supporting plates 16 are symmetrically arranged below the clamping panel 15 and between the outer sleeve 10; a clamping opening 17 is arranged on the clamping panel 15 (see the attached manual). Figure 6 ).

[0027] A locking rod 7 is hingedly connected to the base 1 on one side below the mechanical jack 5; a locking nut 8 is threadedly connected to the upper end of the locking rod 7. A limit pin 18 is installed at the end of the locking rod 7 on one side of the locking nut 8 (see the attached manual). Figure 4 ).

[0028] When the workover rig derrick inclination fine-tuning device is in operation, firstly, the locking nut 8 is loosened to disconnect the locking rod 7 from the clamping seat 6, and then the inclination of the lower derrick 3 is adjusted by the mechanical jack 5 as needed. After the lower derrick 3 is adjusted to a suitable inclination angle, the locking rod 7 is rotated upward to be clamped into the clamping opening 17 of the clamping seat 6, and then the locking nut 8 is tightened to keep the locking rod 7 and the clamping seat 6 fixedly connected. In this way, the purpose of keeping the base 1 and the lower derrick 3 relatively fixed and locked by the locking rod 7 and the clamping seat 6 can be achieved.

[0029] The workover rig derrick inclination fine-tuning device has a compact structure and an ingenious design. The inclination adjustment of the lower derrick 3 can be directly completed by the action of the mechanical jack 5, thereby solving the problems of high energy consumption and high risk when the existing workover rig adjusts the inclination by adjusting the frame chassis by the jack. The workover rig is particularly suitable for the use of the derrick of the workover rig.
