Abstract
The utility model relates to a hydraulic clamping device for drilling machines, which mainly solves the problems of high cost, complicated operation, small clamping force and poor safety of clamping devices on the existing drilling machines. The utility model is characterized in that the upper end of a hydraulic cylinder 3 is hinged on the drilling machine, the lower end of a piston rod of the hydraulic cylinder 3 is hinged with a connecting rod 4 and the other end of the connecting rod 4 is hinged with a connecting rod hinged base 5. The connecting rod hinged base 5 is fixed on a slip base 1, the middle lower part of the connecting rod 4 is hinged with a sliding arm 6 and the sliding arm 6 is fixed with a movable slip 2. The utility model has the characteristics of low cost, rapid operation, large clamping force and high safety.
Description
Technical field:
The utility model relates in the oil drilling field clamping device, especially rig hydraulic clamp used on the wagon drill.
Background technology:
In the oil drilling field, truck-mounted drilling rig is when drilling well, and the loading and unloading drilling rod need be finished with clamping device.And present clamping device has two kinds of forms, and a kind of is hand; A kind of is the worm and gear driving type.Hand device complex operation, and poor stability; The worm and gear driving type, difficult processing, cost height.It is little to also have these two kinds of forms to step up power, influences drilling efficiency.
The utility model content:
For solve clamping device cost height, complex operation on the existing wagon drill, clamping force is little and the problem of poor stability, the utility model provides a kind of rig hydraulic clamp, and this rig hydraulic clamp has that cost is low, swift to operate, clamping force reaches safe and reliable characteristics greatly.
The technical solution of the utility model is: this rig hydraulic clamp comprises by in the fixing stationary slip seat of bracing frame, the stationary slip seat movable slips and hydraulic cylinder being arranged, hydraulic cylinder upper end hinge is on wagon drill, hydraulic cylinder piston rod lower end hinge has connecting rod, the other end of connecting rod and connecting rod free bearing be hinge mutually, the connecting rod free bearing is fixed on the slip spider, connecting rod middle and lower part hinge has push-pull arm, and push-pull arm and movable slips fix.
The utlity model has following beneficial effect: this rig hydraulic clamp is owing to take such scheme, owing to driving movable slips chucking by stretching of hydraulic cylinder piston rod or unclamping, thereby realized loading and unloading purpose, and had that cost is low, swift to operate, clamping force reaches safe and reliable characteristics greatly drilling rod.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
1-stationary slip seat among the figure, the movable slips of 2-, 3-hydraulic cylinder, 4-connecting rod, 5-connecting rod free bearing, 6-push-pull arm.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, this rig hydraulic clamp comprises by in the fixing stationary slip seat 1 of bracing frame, the stationary slip seat 1 movable slips 2 and hydraulic cylinder 3 being arranged, hydraulic cylinder 3 upper end hinges are on wagon drill, hydraulic cylinder 3 piston-rod lower end hinges have connecting rod 4, the other end of connecting rod 4 and connecting rod free bearing 5 be hinge mutually, connecting rod free bearing 5 is fixed on the slip spider 1, and connecting rod 4 middle and lower part hinges have push-pull arm 6, and push-pull arm 6 fixes with movable slips 2.Piston rod by hydraulic valve control hydraulic cylinder 3 is flexible, and because of hydraulic cylinder 3 one ends are fixed on the wagon drill, and the other end hinge of connecting rod 4 is on connecting rod free bearing 5, like this when the piston rod of hydraulic cylinder 3 is flexible, push-pull arm 6 drive activity slips 2 are unclamped or tightens.Thereby realized the connection of drilling rod or dismounting purpose, and had that cost is low, swift to operate, clamping force reaches safe and reliable characteristics greatly.
Claims (1)
