[0001] This utility model relates to a motor moving device for an oil pumping unit, and more particularly to a sliding rail locking type motor moving device for a beam-type oil pumping unit. Background Technology
[0002] In oilfield pumping, a motor moving device must be installed on the pumping unit to enable rapid motor movement and convenient adjustment. The requirements for the motor moving device in Q / SH CG0221.5-2023 "Technical Specifications for Procurement of Oil (Gas) Equipment Part 5: Pumping Units" are as follows: The worm gear mechanism drives the lead screw to rotate, enabling the motor to move rapidly; b) The mobile device has a self-locking function.
[0003] Based on this requirement, the pumping unit motor moving device adopts a worm gear and screw structure to quickly move the motor back and forth, saving labor and facilitating operation. After the motor moves, it also needs to quickly self-lock. The original self-locking structure involved drilling two holes on the outside of the sliding sleeves of the four welded angle steel members, welding a nut to the outside of each hole, and locking the motor base by tightening the set bolts, thus fixing the motor. However, this locking method required tightening eight set bolts and constantly changing their positions, resulting in a large workload for the workers. Utility Model Content
[0004] The purpose of this utility model is to provide a sliding rail locking motor moving device for a beam pumping unit that is simple in structure, easy to use, reduces the difficulty and intensity of operator labor, and improves operator safety, so as to solve the problems in the prior art.

The bottom surface of the fixed angle steel is provided with elongated holes. The fixed frame is connected to the motor base by multiple sets of T-bolts. Two holes are drilled on the vertical surfaces of the two ends of the fixed angle steel for installing two internal pull shafts. A hole is drilled on the middle vertical surface of one of the fixed angle steels for installing a worm gear screw assembly. The motor base includes a sliding sleeve, a herringbone screw threaded sleeve, and a motor connecting angle steel assembly, wherein the herringbone screw threaded sleeve is welded to the motor connecting angle steel assembly; The base connecting bolt group and the motor connecting bolt group are respectively connected to the base and the motor.
[0006] Furthermore, the slide rail is a slide rail steel pipe, and a short section with internal threads is welded to the inner wall of one end of the slide rail steel pipe for adjusting the inner pull-up shaft. Three long slots are evenly arranged in the middle of the slide rail steel pipe for installing the movable cone block.
[0007] Furthermore, the sliding sleeve is a steel pipe with an inner diameter larger than the outer diameter of the slide rail steel pipe. The sliding sleeve can slide on the slide rail steel pipe. The motor connecting angle steel assembly is welded together from two motor base connecting angle steels and two reinforcing angle steels. The motor base connecting angle steels are provided with four long slots, and the motor base is connected to the motor by bolts.
[0008] Furthermore, the inner elongated shaft consists of a shaft body and a square end with external threads, and two conical rings are welded onto the shaft body.
[0009] Furthermore, there are six movable cone blocks, the width of which matches the width of the three long slots on the slide rail steel pipe, and the inner taper of the movable cone blocks is consistent with the taper of the cone ring on the inner elongated shaft.
[0010] The advantages of this invention are: simple structure, convenient use, reduced labor difficulty and intensity for operators, improved operator safety, and quick and reliable replacement of motor belts or pulleys. Operators only need to operate the worm gear and the nut on the inner pull shaft at the motor end to move and lock the motor, eliminating the need for running back and forth.

Detailed Implementation
[0016] A sliding rail locking motor moving device for a beam pumping unit, the moving device comprising a fixed frame, a motor base, a worm gear screw assembly 7, an inner pull-out shaft 3, a movable cone block 8, a base connecting bolt assembly 9, and a motor connecting bolt assembly 10; The fixed frame includes two sets of fixed angle steels 1 and slide rails 2. The bottom surface of the fixed angle steels 1 is provided with elongated holes. The fixed frame is connected to the motor base by multiple sets of T-bolts. Two holes are drilled on the vertical surfaces of the two ends of the fixed angle steels 1 for installing two internal pull shafts 3. A hole is drilled on the middle vertical surface of one of the fixed angle steels 1 for installing a worm gear screw assembly 7. The motor base includes a sliding sleeve 5, a herringbone screw threaded sleeve 4, and a motor connecting angle steel assembly 6, wherein the herringbone screw threaded sleeve 4 is welded to the motor connecting angle steel assembly 6; The base connecting bolt group 9 and the motor connecting bolt group 10 are respectively connected to the base and the motor.
[0017] The slide rail 2 is a slide rail steel pipe. A short section with internal threads is welded to the inner wall of one end of the slide rail steel pipe for adjusting the inner pull-up shaft 3. Three long slots are evenly arranged in the middle of the slide rail steel pipe for installing the movable cone block 8.
[0018] The sliding sleeve 5 is a steel pipe with an inner diameter larger than the outer diameter of the steel pipe of the slide rail 2. The sliding sleeve 5 can slide on the steel pipe of the slide rail 2. The motor connecting angle steel group 6 is welded together from two motor base connecting angle steels and two reinforcing angle steels. The motor base connecting angle steels are provided with four long slots, and the motor base is connected to the motor by bolts.
[0019] The inner elongated shaft 3 consists of a shaft body and a square end with external threads, and two conical rings are welded on the shaft body.
[0020] There are six movable cone blocks 8, the width of which is adapted to the width of the three long slots on the steel pipe of the slide rail 2, and the inner taper of the movable cone block 8 is consistent with the taper of the cone ring on the inner elongation shaft 3.
[0021] The working principle of this utility model is as follows: the handwheel of the rotating worm gear screw assembly 7 drives the rotating screw, and the screw drives the motor to move back and forth through the herringbone screw threaded sleeve 4 fixed on the motor base; by loosening or tightening the screw nut, the thickness of the conical ring on the inner pull shaft 3 and the movable cone block 8 are adjusted to make the outer circle of the movable cone block 8 smaller or larger, so that the movable cone block 8 separates from or is pressed against the inner circle of the sliding sleeve 5, thereby unlocking and locking the movement of the motor; the four elongated holes on the fixed frame and the four elongated holes on the motor base are used to adjust the left and right position of the motor.
[0022] When moving the motor quickly: Loosen the nut at the end of the inner pull shaft 3, the inner pull shaft 3 moves backward, the thickness of the conical ring on the inner pull shaft 3 and the movable conical block 8 becomes thinner, the outer circle of the movable conical block 8 becomes smaller, and it separates from the inner hole of the sliding sleeve 5, so that the motor can move freely; then rotate the worm gear handwheel to drive the rotating screw, and the screw drives the motor to move back and forth through the herringbone screw threaded sleeve 4 fixed on the motor base.
[0023] Before moving the motor forward and backward, you must first loosen the nut at the front end of the inner pull shaft 3 to unlock the motor.
[0024] When fixing the motor: Rotate the handwheel of the worm gear screw assembly 7 to rotate the screw. Stop rotating the worm gear handwheel after the motor is in position. Tighten the screw nut with a special wrench. The conical ring on the inner elongated shaft 3 and the movable conical block 8 move towards each other along the taper direction. The thickness of the contact area between the conical ring on the inner elongated shaft 3 and the movable conical block 8 increases, and the outer circle of the movable conical block 8 increases. The movable conical block 8 and the inner circle of the sliding sleeve 5 are pressed together, thereby locking the movement of the motor and fixing the motor.
