Abstract

The utility model relates to a kind of marine drilling platform technical field, particularly a kind of hydraulic control chela mechanism of fully automatic hydraulic grab pipe machine.The connector of this device is connected with rotary part by adapter sleeve, rotary part is connected with crossbeam connector, rotary part also can drive crossbeam connector to rotate built with floating bearing, hanging pawl weldment is arranged in the slideway of crossbeam connector lower end, crossbeam connector is hung pawl weldment and slides in the slideway of crossbeam connector lower end with hanging to be connected fluid cylinder between pawl weldment and can be driven by fluid cylinder, hang in the middle of pawl weldment and install two movable hanging pawls, movable hanging pawl controls to hang opening and firmly grasping of pawl by fluid cylinder.The utility model achieves the pipe that once can capture many different-diameters, and operating efficiency is high, and everything adopts hydraulic-driven completely, and alleviate the labour intensity of operating personnel, floor space is little, safe and reliable, and running cost is low.

Description

A kind of hydraulic control chela mechanism
Technical field:
The utility model relates to a kind of marine drilling platform technical field, particularly a kind of hydraulic control chela mechanism of fully automatic hydraulic grab pipe machine.
Background technology:
At present, on marine drilling platform pipe stockyard, by pipe, the mode be placed on cat road has: manpower and lifting device.Danger is high, efficiency is low, labour cost is high to rely on manpower to be shifted onto by pipe on cat road; Adopt lifting device model of getting pipe capable of hoisting limited, and the pipe of different model needs the lifting device changing different model, cost is high; Can lift a pipe, efficiency is too low at every turn.
Utility model content:
The technical problems to be solved in the utility model is to provide a kind of hydraulic control chela mechanism, the arrangement achieves the pipe that once can capture many different-diameters, operating efficiency is high, everything adopts hydraulic-driven completely, alleviate the labour intensity of operating personnel, floor space is little, safe and reliable, and running cost is low.Overcome the existing mode efficiency be placed into by pipe on cat road low, cost is high, dangerous reliable deficiency.
Technical solution adopted in the utility model is: a kind of hydraulic control chela mechanism, comprises connector, adapter sleeve and movable hanging pawl, connector is connected with rotary part by adapter sleeve, rotary part is connected with crossbeam connector, rotary part also can drive crossbeam connector to rotate built with floating bearing, hanging pawl weldment is arranged in the slideway of crossbeam connector lower end, crossbeam connector is hung pawl weldment and slides in the slideway of crossbeam connector lower end with hanging to be connected fluid cylinder between pawl weldment and can be driven by fluid cylinder, hang in the middle of pawl weldment and two movable hanging pawls are installed, movable hanging pawl controls to hang opening and firmly grasping of pawl by fluid cylinder, hang pawl weldment both sides and all position-limit mechanism is installed, position-limit mechanism is driven by fluid cylinder can the drilling tool caught of descending compression movable hanging pawl.
The beneficial effects of the utility model are: the utility model once can capture the pipe of many different-diameters, and operating efficiency is high, and everything adopts hydraulic-driven completely, and alleviate the labour intensity of operating personnel, floor space is little, safe and reliable, and running cost is low.
Accompanying drawing illustrates:
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
As shown in Figure 1, a kind of hydraulic control chela mechanism, comprises connector 1, adapter sleeve 2 and movable hanging pawl 6; By connector 1, the utility model is connected with fully automatic hydraulic grab pipe machine.Connector 1 is connected with rotary part 3 by adapter sleeve 2, in adapter sleeve 2 inside, load transducer is housed, and after chela lands and loses load, adapter sleeve 2 can provide one section of buffer distance, guarantees that each connecting pin or mechanical part can not be impacted, causes damage.Rotary part 3 is connected with crossbeam connector 4, rotary part 3 also can drive crossbeam connector 4 to rotate built with floating bearing, hanging pawl weldment 5 is arranged in the slideway of crossbeam connector 4 lower end, crossbeam connector 4 is hung pawl weldment 5 and slides in the slideway of crossbeam connector 4 lower end with hanging to be connected fluid cylinder between pawl weldment 5 and can be driven by fluid cylinder, thus the bias produced during adjustment crawl load.Hang in the middle of pawl weldment 5 and two movable hanging pawls 6 are installed, movable hanging pawl 6 stretching out and withdrawal by fluid cylinder, movable hanging pawl 6 is rotated around fixed axis, thus realize firmly grasping and unclamping of chela, hang pawl weldment 5 both sides and be all provided with position-limit mechanism 7, position-limit mechanism 7 is driven by fluid cylinder can the drilling tool caught of descending compression movable hanging pawl 6.
Be understandable that, above about specific descriptions of the present utility model, the technical scheme described by the utility model embodiment is only not limited to for illustration of the utility model, those of ordinary skill in the art is to be understood that, still can modify to the utility model or equivalent replacement, to reach identical technique effect; Needs are used, all within protection domain of the present utility model as long as meet.
