Description

Technical Field

[0001] This utility model relates to a hook load test device for workover rigs, belonging to the field of workover rig testing technology. Background Technology

[0002] Currently, well workover rig hook load tests primarily employ two methods: pin-and-counterweight hook load tests and ground anchor cylinder loading tests. Pin-and-counterweight hook load tests involve testing large-tonnage combined counterweights underground, which requires improvement in terms of testing efficiency, construction costs, and safety. This method requires excavating a deep pit equipped with pin holes for the counterweight combination. When the counterweight needs to be changed during the hook load test, operators must descend into the pit to select the counterweight weight, insert the pin, and hook it up. Due to the requirements of testing different lifting conditions, operators need to repeatedly descend into the pit to adjust the counterweight weight, which is time-consuming, labor-intensive, and results in low debugging efficiency. Because the test conditions require the lifting point to be close to the ground, the hook load position is low, and the entire counterweight is below ground level, resulting in a deep pit and certain safety hazards. When the well workover rig is deployed, it occupies a large area, necessitating a dedicated test area. Protective railings must be installed around the deep pit test area, and the top must be covered with a protective cover, posing safety hazards and potential for water accumulation. This dedicated testing area restricts the use of other vehicles, leading to low land utilization. The perimeter of the deep pit infrastructure test area and the parking area of ​​the test site need to be reinforced with concrete to prevent ground collapse caused by gravity and potential test accidents. The ground anchor cylinder loading test involves constructing an underground room with a pre-embedded hydraulic tensioning device. A hydraulic pump drives a hydraulic cylinder to generate reverse tension. The hydraulic cylinder pressure is monitored, and the lifting weight is calculated using software. This method requires a significant investment but can automate the lifting and loading process. However, due to the deep underground location, the entire equipment must be covered with a protective cover, posing safety hazards and potential water accumulation issues. Utility Model Content

[0003] In order to overcome the problems of low efficiency, high cost, significant safety hazards, and low land utilization in the existing well workover rig hook load test, this utility model provides a well workover rig hook load test device to reduce costs, improve efficiency, eliminate safety hazards, and enhance land utilization.

[0004] This utility model is achieved through the following technical solution: a well workover rig hook load test device, including a pre-embedded hook load fixture, a protective plate above the device, and a concrete foundation; the pre-embedded hook load fixture includes a lifting column and a fixture lifting point shaft, the lifting column being fixed on the fixture lifting point shaft; the pre-embedded hook load fixture and the steel reinforcement frame are pre-embedded together in the concrete foundation; the protective plate above the device is laid on the concrete foundation to cover the pre-embedded hook load fixture.

[0005] It also includes a rope tensioning device, and a protective plate is provided above the rope tensioning device.

[0006] The workover rig is connected to the lifting column or tooling lifting point shaft via flexible slings or single-arm lifting rings and valve clamps.

[0007] The steel reinforcement cage is arranged through civil construction and, together with the pre-embedded hook-load tooling, forms a concrete foundation through concrete pouring.

[0008] The tensioning device is used for testing large-tonnage hook loads. During the test, the protective plate above the tensioning device needs to be removed.

[0009] The pre-embedded hook loaders, steel reinforcement cage, and concrete foundation form an integrated structure.

[0010] The beneficial effects of this utility model are as follows: Compared with the prior art, this utility model has low manufacturing costs and no subsequent maintenance costs after the one-time construction investment; the overall hoisting and hooking operation is convenient and the debugging efficiency is improved by 48%; after the test is completed, a protective board is laid on top, there are no other guardrail facilities on the ground, vehicles can pass normally, and the utilization rate of public space is high; there is no deep pit structure, so there are no safety and water accumulation problems.
