Abstract
Disclosed in the utility model is a drilling machine load test apparatus, so that problems of tedious operation, high cost, and existence of great potential safety hazard in the prior art can be solved. The load test apparatus comprises: a hydraulic control system; a hydraulic cylinder, which is provided with a piston rod and is communicated with the hydraulic control system by a pipeline; a connecting seat, which is connected with the bottom of the hydraulic cylinder; and a lift sub, which is connected with the piston rod. Besides, lugs are arranged on the connecting seat. According to the utility model, the drilling machine load test apparatus has advantages of simple structure, high bearing capacity, small occupied area, convenient operation, security and reliability, and easiness of popularization and usage.
Description
Technical field
The utility model belongs to the oil-well rig manufacturing field of equipment, specifically the auxiliary equipment rig load test apparatus of oil-well rig.
Background technology
At present, the problem that loads in order to solve oil-well rig boring tower base load test, generally adopt the mode of direct cheek weight under rig substructure, as: the rig load is 500 tons, just under base, suspend 500 tons test mass piece in midair, this mode complex operation, equipment cost is high, also has great potential safety hazard simultaneously.
The utility model content
The purpose of this utility model is to provide a kind of rig load test apparatus, solves complex operation in the prior art, and cost is high, has simultaneously the problem of great potential safety hazard.
To achieve these goals, the technical solution adopted in the utility model is as follows:
The rig load test apparatus comprises hydraulic control system, with the hydraulic cylinder with piston rod that hydraulic control system is connected by pipeline, the Connection Block that is connected with the hydraulic cylinder bottom, and the elevator that links to each other with piston rod.
Further, also be provided with the ear seat on the described Connection Block.
Again further, described hydraulic cylinder links to each other with Connection Block by bearing pin.
Further, be provided with groove on the described piston rod.
In addition, described elevator is drill pipe elevator.
Compared with prior art, the utlity model has following advantage and beneficial effect:
(1) the utility model adopts single hydraulic cylinder to replace using weight to load, simple to operate, safety, and the hydraulic cylinder cost is well below the test mass piece;
(2) the utility model hydraulic cylinder and Connection Block, and Connection Block all adopts bearing pin to be connected with rig substructure, easy to connect and bearing capacity is strong;
(3) the utility model piston rod is provided with groove, and elevator can directly be stuck on the piston rod, need not other connections, and is easy to operate;
(4) the utility model hydraulic control system can be used the hydraulic control system that rig carries, and need not special outfit, saves cost;
(5) the utility model is simple in structure, and bearing capacity is large, takes up an area littlely, easy to operate, safe and reliable, is easy to promote the use of.
Description of drawings
Fig. 1 is the structural representation of the utility model-embodiment.
Wherein, the parts name that mark is corresponding in the accompanying drawing is called: the 1-hydraulic control system, and the 2-hydraulic cylinder, the 3-Connection Block, the 4-elevator, the 5-piston rod, 6-ear seat, the 7-bearing pin, the 8-drilling derrick, 9-drilling well base, 10-swims crane system.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples, and embodiment of the present utility model includes but not limited to the following example.
Embodiment
As shown in Figure 1, the rig load test apparatus comprises hydraulic control system 1, with the hydraulic cylinder 2 with piston rod 5 that hydraulic control system 1 is connected by pipeline, the Connection Block 3 that is connected with hydraulic cylinder 2 bottoms, and the elevator 4 that links to each other with piston rod; And also be provided with ear seat 6 on the described Connection Block 3, present embodiment ear seat is set to 4, and elevator is selected drill pipe elevator.
Connect and assurance bearing capacity intensity for convenient, link to each other with Connection Block 3 by bearing pin 7 at described hydraulic cylinder 2.
For the more convenient elevator that makes is installed on the piston rod, so be provided with groove in described piston rod 5 upper ends.
This test unit is derrick, base one test fexible unit, when this utility model is used, 4 ear seats of this utility model is connected with rig substructure 9 by bearing pin, and elevator is passed through wire rope or suspension ring are connected with trip crane system 10; Operate subsequently hydraulic control system, make oil enter oil cylinder, liquid presses piston pole just moves down, and at this moment, drilling derrick 8 is subject to the downward pulling force of piston rod; The fluid cylinder bottom links to each other with Connection Block, and rig substructure is applied pulling force upwards.When the fluid cylinder pulling force reaches the requirement of rig load test pulling force, finish the load test of rig.
According to above-described embodiment, just can realize well the utility model.
