Description
Technical field
The utility model belongs to petroleum machinery apparatus field, relates in particular to a kind of petroleum machinery nut changer.
Background technology
At present, the large-scale nut on petroleum machinery equipment, great majority are all to utilize large-scale wrench screw and become flexible by manpower, not only labour intensity is large, and production efficiency is low; If oil field equipment submersible electric pump, oil well pump etc. are when manufacturing and two ends large-scale nut is assembled in maintenance, the large-scale wrench of common employing 2500-2700 nosebleed is screwed by all one's effort by two workmans, because nut screws certain moment requirement, so assembly precision is difficult to reach requirement, assembly quality is unstable.Because screw-down torque is difficult to control, thus moment too young pathbreaker cause roll play normally to work, moment too greatly increases dismantles difficulty; Motor is often placed on fuel tank, and carrys out damping by adding damper, but is subject to force direction still can affect dismounting nut time, causes nut to be worn.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides a kind of petroleum machinery nut changer, and dismounting angle is adjustable, and be not subject to the impact of motor oscillating, and accurate to the dismounting of nut, wear and tear less, also be suitable for some fields to nut required precision simultaneously, easy to loading and unloading.
To achieve these goals, the present invention adopts following technical scheme:
A kind of petroleum machinery nut changer, comprise fuel tank, hydraulic motor, beam hanger, motor, described hydraulic motor is by bearings, described hydraulic motor one end is connected with driving member, the other end is connected with gear, described driving member is connected with nut Fastener, its special character is that described hydraulic motor below is provided with lowering or hoisting gear, between described lowering or hoisting gear and described hydraulic motor, be provided with roller bearing, described roller bearing and described bearing are in the same plane, described fuel tank is provided with display, described display is connected with torque sensor, described torque sensor is connected with described hydraulic motor, described motor is connected by beam hanger with described hydraulic motor, described motor is arranged on supporting seat, described supporting seat is positioned at described fuel tank one side.
Described lowering or hoisting gear comprises hoistable platform, spring, joystick, and described hoistable platform is arranged on described hydraulic motor below, and described hoistable platform has described spring, and described hoistable platform is connected with described joystick.
Described driving member is rotating shaft.
Described nut Fastener is the nut sleeve matching with nut.
The beneficial effects of the utility model are: motor is arranged on supporting seat, rather than are arranged on fuel tank, affected by motor oscillating little, the direction while having guaranteed dismounting, and nut is not easy to wear; During for the nut dismounting of big machinery, can take roller bearing as the strong point rotates whole attaching/detaching apparatus, according to the angle of the direction adjustment device of nut, can regulate according to the height of nut the height of lowering or hoisting gear, can carry out the nut dismounting of big machinery different angles differing heights, convenient and strength-saving; Adopt hydraulic principle, utilize adjustment hydraulic system pressure to guarantee required moment, not only replaced the heavy manual labor of workman, improved production efficiency, and clamp load torque is adjustable, thereby the pretightning force of any nut of each product can be all consistent on each part product, product quality is guaranteed.The utility model is simple in structure, is suitable for petroleum machinery, and production assembling and the maintenance of the heavy mechanical equipments such as mining machinery are used.
Accompanying drawing explanation
