Abstract
The utility model relates to a tool used for fastening and disassembling, which makes the reciprocating movement of a hydraulic oil cylinder converted into unidirectional rotation through a group of ratchet wheels and drives a hexagonal sleeve barrel to automatically fasten and disassemble screw bolts and screw nuts. The utility model has the advantages of simple structure, big torque, stable working and safety, and is an ideal tool for the assembly, inspection and repair of mechanical containers and pressure containers in the petrochemical industry, the power generation industry, the shipbuilding industry, the bridging industry, the architecture industry, the installation industry, etc.
Description
The utility model relates to a kind of portable power tools, especially for instrument fastening, dismounting.
Past is fastening with spanner, dismounting king-bolt, nut are to pull with hand, because effort is usually by means of sleeve pipe, sledgehammer, crane etc., the someone had invented autowrench afterwards, but that their shortcoming is a moment is little, can not be satisfied with various big bolts, nut tight, unload needs.
The purpose of this utility model provides a kind of simple in structure, general hydraulic spanner, and it can have enough torques to rotate bigger bolt, nut, and stable working is safe and reliable.
The technical solution of the utility model is: a kind of hydraulic spanner, have six square sockets, on this six square sockets bar, support plate arranged, wave ratchet, just overlap ratchet, on side's cover ratchet, spring is arranged, and the spring bracket of fixing this spring, it is characterized in that: also have an oil cylinder that is fixed on the support plate, the piston rod of oil cylinder links together with waving ratchet by bearing pin, and the oilhole at oil cylinder two ends is connected by motor-driven reversal valve and oil inlet pipe, oil return pipe.
Its bore of six square sockets of the present utility model can be designed as multiple model.
Because it is power that this instrument adopts hydraulic drive, can obtain very big torque when rotating the king-bolt nut, and stable working, impact little.The bore of six square sockets is multiple model, just can adapt to during work the needs of various bolts, nut and hydraulic transmission technology have can pressure regulation characteristics therefore this instrument reached in very large range general purpose.This instrument adopts motor-driven reversal valve, and it is simple in structure, so also have little, in light weight, the safe and reliable advantage of volume.
Below with reference to accompanying drawing embodiment of the present utility model is further specified.
Fig. 1 is the structural representation of hydraulic spanner.
Fig. 2 is the vertical view of Fig. 1.
1 six square sockets, 2 wave ratchet, 3 sides cover ratchet, 4 springs, 5 spring brackets, 6 oil inlet pipes, 7 oil return pipes, 8 support plates, 9 motor-driven reversal valves, 10 oil cylinders, 11 piston rods, 12 bearing pins among the figure.
Six square sockets (1) are the workpieces of spanner, and it has designed serial accessory according to the different bores of target.The tube bar of six square sockets (1), a part is a cylinder, a part is a square body, column part and support plate (8), the hole of waving ratchet (2) cooperate, and can rotate, square column partly with just overlap ratchet (3) square hole and cooperate.Side cover ratchet (3) and wave ratchet (2) two flank of tooth and contact, spring (4) side of being pressed in is overlapped on the ratchet (3), and spacing by the spring bracket (5) that is fixed on six square socket bars (1) end.Characteristics of the present utility model are that also to have a hydraulic system be power, wherein hydraulic jack (10) is fixed on the support plate (8), the piston rod of oil cylinder (11) with wave ratchet (2) together by bearing pin (12) hinge joint, the oilhole on oil cylinder (10) both sides is connected with the motor-driven reversal valve (9) of oil cylinder outside, and this valve is connected fuel feed pump (6) and oil return pipe (7).When the hydraulic oil that comes when fuel feed pump (6) is defeated makes the reciprocating motion of the pistons of oil cylinder (10) by reversal valve (9), it serves as that axle swings with bearing pin (12) that piston rod (11) just promotes to wave ratchet (2), is fixed on the support plate because wave the center of circle of ratchet (2).Side cover ratchet (3) under the pressure of spring (4) all the time with wave ratchet (2) and contact, the side's of the making cover ratchet (3) that swings that waves ratchet (2) has obtained power, because the square hole of side's cover ratchet divides with the tube bar square column part of six square sockets and cooperates, so their synchronous one-directional rotation under the support of support plate (8).When the head that changes six square sockets to the time, can obtain to reciprocal rotation.
Claims (2)
1, a kind of hydraulic spanner, have six square sockets, on this six square sockets bar, support plate is arranged, wave ratchet, side's cover ratchet, the spring bracket that spring is arranged and fix this spring on side's cover ratchet is characterized in that: also have an oil cylinder that is fixed on the support plate, the piston rod of oil cylinder links together with waving ratchet by bearing pin, and the oilhole at oil cylinder two ends is connected by motor-driven reversal valve and oil inlet pipe, oil return pipe.
2, according to the said a kind of hydraulic spanner of claim 1, it is characterized in that: its bore of six square sockets is multiple model
