Abstract
The utility model relates to well head equipment of a pumping well in an oil field, particularly to a thievery prevention device for a motor fixing bolt. A motor base is fixed on a motor track through a motor fixing bolt group, an insertion block is inserted into the lower part of the side plate of the motor base, two symmetrically arranged connectors are tightly attached on the side plate of the motor base, an insertion pin at the lower part of a disassembly prevention cover is inserted into an insertion slot on each connector, the disassembly prevention cover is arranged on each connector and is provided with an open slot and a window, the width of the window is larger than that of the open slot, the width of the bolt is larger than that of the open slot and is smaller than the width of the window, a bolt base is arranged on the inner bottom surface of each disassembly prevention cover, the male threads of the bolt are connected with the female threads of the insertion block, and two symmetrically arranged thievery prevention sleeves are fixed at one ends of the connectors and sheath the motor fixing bolt group. The thievery prevention device is fixed by virtue of a motor structure, so that thieves can not disassemble the motor fixing bolt group and can not stole the motor and pumping unit accessories, thereby avoiding various economic losses due to the motor of the pumping unit being stolen.
Description
Technical field
The utility model belongs to the oil field pumping well wellhead equipment, particularly a kind of motor fixing bolt anti-theft device.
Background technique
In the oil pumping of oil field, pumping unit drives sucker rod, oil well pump is extracted oil out in well, essential installation motor on the pumping unit, and motor is fixed on the base by the bolt group.Because it is limited that motor is installed the space at screw place, the theft protection screw can not be installed, steal and after molecule is easy to plain nut dismantled motor to be stolen, cause that oil well stops production, after pumping unit shuts down, steal molecule and also the accessory on the pumping unit can be stolen, cause the loss of manufacturing mechanism and crude oil, produce heavy economic losses.
Summary of the invention
The purpose of this utility model provides a kind of motor fixing bolt anti-theft device, prevent to steal molecule dismantle with sawed-off motor retaining screw after steal motor and pumping unit accessory, avoid the various economic losses that cause because of pumping-unit motor is stolen.
The purpose of this utility model has been achieved in that motor fixing bolt group, motor base, the motor track, the motor base side plate, motor base is fixed on the motor track by motor fixing bolt group, motor fixing bolt group, motor base, the motor track, the motor base side plate is two of symmetries, also has burglarproof sleeve, connecting body, the tamper cover, bolt, inserted block, inserted block inserts the bottom of motor base side plate, connecting body is attached to above the motor base side plate, pin is arranged at tamper cover bottom, slot is arranged on the connecting body, in the slot on the pin reeve connecting body of tamper cover bottom, tamper cover seat is on connecting body, tamper is covered with opening slot, tamper is covered with window, the width of window is greater than the width of opening slot, the width of bolt is greater than the width of opening slot, the width of bolt is less than the width of window, bolt is put into from window, bolt block is at the inner bottom surface of tamper cover, the male thread of bolt is connected with the box thread of inserted block, burglarproof sleeve is fixed on connecting body one end, burglarproof sleeve entangles motor fixing bolt group, and the connecting body symmetry is installed two, and the burglarproof sleeve symmetry is installed two.
The beneficial effects of the utility model are: utilize the structure of motor that anti-theft device is fixed, thief can't be dismantled motor fixing bolt group, can not steal motor and pumping unit accessory, has avoided the various economic losses that cause because of pumping-unit motor is stolen.
