Detailed Description

The embodiments of the invention will be described in detail below with reference to fig. 1 to 3, but the invention can be implemented in many different ways as defined and covered by the claims.

It should be noted that the following description of the embodiments refers to the accompanying drawings, in which like numerals refer to the same or similar elements throughout the different views, unless otherwise specified.

It is also to be understood that the following detailed description is exemplary and is intended to provide further explanation of the invention as claimed, unless otherwise specified, and all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs.

Specific embodiments of the present application will now be described in detail with reference to fig. 1 to 3, however, these embodiments may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, it being understood that these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the concept of these embodiments to those skilled in the art.

As the technical problems to be solved as described in the background art, at present, the motor is fastened on the base 1 through bolts, the base 1 is fastened on the slide rail 2 through bolts, when the motor is moved to operate, the worker rotates the jackscrew 4 sleeved in the screw sleeve 3, so that the jackscrew 4 acts on the side face moving motor of the base 1, the screw sleeve 4 is fixedly welded on the slide rail 2 at present, so that the jackscrew 4 penetrating through the screw sleeve 3 is always positioned at the upper part of the slide rail 2, when other operations are carried out, the jackscrew 4 is easy to be accidentally damaged to cause the situation that the screw rod is bent or the screw thread is damaged, the utility model aims to realize that the jackscrew 4 which is arranged in the screw sleeve 3 in a penetrating way can enter the slide rail 2 by realizing the lifting of the screw sleeve 3, therefore, the sliding rail 2 protects the jackscrew 4 from being hit by external force, and the aims of improving safety and improving production efficiency are fulfilled.

With reference to fig. 1 to 3, the utility model provides a lifting type beam-pumping unit motor jackscrew support, which comprises a threaded sleeve 3 for penetrating a jackscrew 4, wherein the threaded sleeve 3 is fixedly arranged on the upper surface of a mandril 8, the mandril 8 is longitudinally movably arranged inside a slide rail 2, a guide ring 10 coaxial with the mandril 8 is arranged outside the mandril 8, a positioning disc 11 is fixedly arranged in the middle of the mandril 8, and a spring 9 is sleeved on the mandril 8 between the upper surface of the positioning disc 11 and the lower surface of the guide ring 10; a wedge-shaped block 6 is movably arranged in the slide rail 2, a guide groove 14 is formed in the inclined surface of the upper part of the wedge-shaped block 6 along the longitudinal direction, and the guide groove 14 can be matched with the lower part of the ejector rod 8; a bolt 5 is arranged transversely through the sliding rail 2, the end of the bolt 5 being able to act on the side of the wedge block 6.

According to the structure of the above embodiment, due to the characteristics of the spring 9, under the condition that the guide ring 10 is fixed, the spring 9 can provide a downward acting force to the positioning plate 11, so that the ejector rod 8 moves downward, when the worker slowly unscrews the bolt 5, the ejector rod 8 moves downward along with the left movement of the wedge-shaped block 6, in the process that the ejector rod 8 moves downward, the threaded sleeve 3 is fixedly arranged on the ejector rod 8, so that the threaded sleeve 3 moves downward along with the ejector rod 8, and the jackscrew 4 penetrating through the threaded sleeve 3 moves downward, when the jackscrew 4 moves downward to the lower part of the upper surface of the slide rail 2, the jackscrew 4 is protected by the slide rail 2, and the acting force from the outside cannot directly act on the jackscrew and the screw buckle thereof.

When the staff need use jackscrew 4 to remove the motor, only need screw bolt 5 for bolt 5 promotes wedge 6 and moves to the right, and at this moment ejector pin 8 will move up along with the right side of wedge 6 moves, when ejector pin 8 moves up and makes swivel nut 3 be higher than the upper surface of slide rail 2, just can rotate the jackscrew 4 of wearing to establish among swivel nut 3 and promote base 1, thereby remove and base 1 fixed connection's motor.

With reference to fig. 1 to 3, the width of the wedge block 6 is smaller than the width of the slide rail 2.

The utility model discloses an in the above-mentioned embodiment, wedge 6's width is less than slide rail 2's width, wedge 6 can realize 8 longitudinal movement of ejector pin in the lateral shifting in-process, consequently, must make it can produce lateral displacement in the inside of slide rail 2, and in the actual implementation process, its width should be able to guarantee to make the swivel nut 3 on 8 upper portions of ejector pin fall into the inside of slide rail 2 under the prerequisite that is less than the width of slide rail 2.

Referring to fig. 1 to 3, a shaft seat 12 is fixedly arranged below the ejector rod 8, a shaft 13 penetrates through the shaft seat 12, a roller 7 is movably sleeved on the shaft 13, and the roller 7 can be movably matched with the guide groove 14.

The above embodiment of the utility model provides a, by gyro wheel 7 more be favorable to realizing the purpose that this utility model pursued with the cooperation of direction recess 14, both made things convenient for ejector pin 8's lift, easy to maintain simultaneously, life cycle is long, if directly use ejector pin 8's lower part and the cooperation of direction recess 14, just there is the two frictional force great, not only is difficult for realizing ejector pin 8's lift, can appear the problem that wearing and tearing became invalid after using a period moreover, is unfavorable for this utility model to use for a long time.

With reference to fig. 1 to 3, the guide ring 10 is welded to an inner wall of an upper portion of the slide rail 2.

In the above-mentioned embodiment of the utility model, the inner wall welding on preferred guide ring 10 and the upper portion of slide rail 2, guide ring 10 is as the utility model discloses an essential technical feature plays the important role to the direction of ejector pin 8 in concrete implementation process, if do not have guide ring 10 to perform the function, only rely on the horizontal restraint of direction recess 14 to gyro wheel 7, can't implement smoothly this utility model, with its inner wall of welding on the upper portion of slide rail 2, not only can make this utility model implement smoothly, its hiding in the inside of slide rail 2 moreover, do not influence other operations.

The above only is the preferred embodiment of the utility model discloses, is not used for limiting the utility model discloses, to the technical personnel in this field, the utility model discloses can have multiple change and change, all according to the utility model discloses any modification, the equivalent transform etc. that technical scheme was done, the effect of its function and production does not surpass the utility model discloses a technical scheme's scope is all regarded as the utility model discloses a protection scope.
