Description
Technical field
The utility model relates to a kind of device that is used for the petroleum well workover machine operation, particularly a kind of derrick locking device.
Background technology
When the petroleum well servicing rig workover derrick erects, the derrick locking device makes derrick upper body safety, steadily is sitting on the derrick lower body carrier bar, reach the required working depth of derrick, be that derrick upper body, lower body connect, the loading transfer that the upper body is born is given the vitals of lower body, and structurally to guarantee the verticality and the stability of derrick, guarantee that the upper body stretches out safe, steady, put in place.
Summary of the invention
The utility model purpose provides a kind of derrick locking device simple in structure, easy to use.
In order to solve the problems of the prior art, the present invention by the following technical solutions:
A kind of derrick locking device, comprise carrier block, linkage, support, spring and locking bail, this device front end is provided with carrier block, and locking bail is installed on the carrier block, and the locking bail front end is provided with block, this device middle part is provided with support, support is provided with spring, and spring one end is fixed on the support, and an end is connected with linkage, linkage is connected with spring, carrier block and this device rear end respectively, and this device rear end is connected with safety pin.
Compared with prior art, the beneficial effects of the utility model are: simple in structure, easy to use.
Description of drawings
Fig. 1 is the utility model front view
Fig. 2 is the utility model vertical view
Among the figure: 1, carrier block 2, block 3, locking bail 4, spring 5, linkage 6, support 7, safety pin
The specific embodiment
A kind of derrick locking device, comprise carrier block 1, linkage 5, support 6, spring 4 and locking bail 3, this device front end is provided with carrier block 1, and locking bail 3 is installed on the carrier block 1, and locking bail 3 front ends are provided with block 2, this device middle part is provided with support 6, support 6 is provided with spring 4, and spring 4 one ends are fixed on the support 6, and an end is connected with linkage 5, linkage 5 is connected with spring 4, carrier block 1 and this device rear end respectively, and this device rear end is connected with safety pin 7.
The course of work of this device is: the derrick locking device is with carrier block 1 connected mode, when derrick stretch out put in place after, derrick lower body block 2 blocks locking bail 3, make locking bail 3 decontrol carrier block 1, spring 4 pulling linkages 5 releasing bearing pieces 1 are arranged, and carrier block 1 stretches out, and is sitting in simultaneously on the lower body carrier bar; The withdrawal of carrier block 1 is that derrick lower body block 2 blocks locking bail 3 when leaning on the derrick upper body to move up, and makes locking bail 3 pin carrier blocks 1 fixture block, and spring 4 tightens up pulling linkage 5 and regains carrier blocks 1, packs up by the slideway derrick.
