Abstract
The utility model provides a hydraulic chain connector which has a simple structure and is convenient to use. The hydraulic chain connector comprises a manual operating arm (1), a manual hydraulic pump (2), a shutoff valve (3), a hydraulic hose (4), a hydraulic cylinder (5), a piston rod (6), a chain connecting hook (7), a connecting rod (8) and a chain connecting hook (9), wherein the manual operating arm (1) is arranged on the manual hydraulic pump (2) and is connected with the hydraulic cylinder (5) through the shutoff valve (3) and the hydraulic hose (4); and one end of the hydraulic cylinder (5) is connected with the chain connecting hook (7) through the piston rod (6), and the other end of the hydraulic cylinder (5) is provided with the chain connecting hook (9) which is connected with the chain connecting hook (7) through the connecting rod (8). The hydraulic chain connector is safe to use and convenient to control, and has low manufacture cost and good sealing performance. According to the hydraulic chain connector, the purpose of time and labor conservation is achieved, and hidden dangers such as personal injury, downhole safety accidents and the like in the working process of chain connection are eliminated.
Description
Technical field
The utility model relates to a kind of oil drilling device, especially a kind of hydraulic chain connector.
Background technology
At present, the winch that is adopted, rotating disk are the open type transmission, poor lubrication; Chain rupture bar phenomenon often takes place aborning; Need take the work that repeats that connects again apart, waste time and energy, receive the narrow and small influence of the device space at positions such as the winch of drillers such as ZJ40L, ZJ50LDB type and car transmission case, rotating disk transmission cases; Have to tie up the work of carrying out chain to chain with coir rope, very easily cause personal injury and downhole safety accident.
Summary of the invention
The purpose of the utility model is to provide a kind of a kind of hydraulic chain connector simple in structure, easy to use, with low cost.It comprises manual lever, hydraulic hand-pump, stop valve, hydraulic hose, hydraulic cylinder, piston rod, chain link hook, connecting rod and chain link hook.Hydraulic hand-pump is provided with manual lever and is connected with hydraulic cylinder through stop valve, hydraulic hose, and hydraulic cylinder one end connects the chain link hook through piston rod, and the chain link hook that the other end is provided with is connected with the chain link hook through connecting rod.This device is safe in utilization, is convenient to control, and low cost of manufacture and good seal performance use this device promptly to reach time saving and energy saving purpose, has eliminated hidden danger such as the personal injury that causes in the chain course of work and downhole safety accident again.
Description of drawings
Accompanying drawing is the structural representation of the utility model.
The specific embodiment
As shown in the figure, a kind of hydraulic chain connector comprises manual lever 1, hydraulic hand-pump 2, stop valve 3, hydraulic hose 4, hydraulic cylinder 5, piston rod 6, chain link hook 7, connecting rod 8 and chain link hook 9.Hydraulic hand-pump 2 is provided with manual lever 1 and is connected with hydraulic cylinder 5 through stop valve 3, hydraulic hose 4, and hydraulic cylinder 5 one ends connect chain link hook 7 through piston rod 6, and the chain link hook 9 that the other end is provided with is connected with chain link hook 7 through connecting rod 8.During use, utilize the chain link hook 7,9 that is installed on the hydraulic connector two ends, hook respectively on chain two end links that will connect; Piston rod 6 with hydraulic cylinder 5 before the operation reaches on the range, closes stop valve 3, operation hydraulic hand-pump 2; The piston of hydraulic cylinder 5 spurs chain link hook 7 along connecting rod 8 slip retractions under the effect of pressure oil, constantly the chain link with the chain two ends furthers, and detection chain expanding force reaches requirement and chain link arrives suitable position; Chain hinge pin is inserted chain link, open stop valve 3, make hydraulic cylinder 5 pressure releases; Promote piston rod 6 and stretch out, remove chain link hook 7 and 9, promptly accomplish chain link work.This device is safe in utilization, is convenient to control, and low cost of manufacture and good seal performance use this device promptly to reach time saving and energy saving purpose, has eliminated hidden danger such as the personal injury that causes in the chain course of work and downhole safety accident again.
