Abstract
Description
Technical Field
[0001] This utility model relates to the field of coupling installation technology, specifically to a coupling installation device for pump stations. Background Technology
[0002] Currently, the pump station includes a motor, an oil tank, and an oil suction pump. The oil tank has a U-shaped structure, and a coupling is typically installed in a cavity within the upper half of the tank. This coupling connects the motor, located at the left end of the coupling, to the oil suction pump, located at the right end. Specifically, the coupling includes a shaft spline connected to the motor and a spline sleeve connected to the oil suction pump. It can be understood that the spline sleeve and shaft spline, after installation, form a meshing gear structure.
[0003] In existing technology, the spline sleeve of the coupling is usually installed manually first on the oil pump, then the shaft spline of the coupling is installed on the motor, and finally the oil pump and the motor are pushed towards each other, so that the spline sleeve and the shaft spline mesh with each other, thereby completing the purpose of connecting the motor and the oil pump using the coupling.
[0004] However, since both the spline sleeve and the shaft spline are installed manually, there is a situation where the spline sleeve and the shaft spline are not meshed when they are pushed in opposite directions (i.e., the coupling is not effectively connected to the motor and the oil pump). When the spline sleeve and the shaft spline are not meshed, the squeezing between them will cause damage to the tooth structure of the spline sleeve and the shaft spline.
[0005] Therefore, there is an urgent need for a coupling installation device for pump stations, which can first align the tooth structure and clearance of the spline sleeve and the shaft spline, and then push them towards each other so that the spline sleeve and the shaft spline mesh with each other, thereby achieving the purpose of connecting the motor and the oil pump using the coupling. Utility Model Content
[0006] To solve the aforementioned technical problems, this utility model provides a coupling installation device for pump stations. Firstly, the rotation direction and angle of the annular gear sleeve can be controlled using a gripping component (specifically, a rotating handle), thereby synchronously controlling the rotation direction and angle of the shaft spline and spline sleeve. Secondly, when the angle between the gripping component (specifically, a marker rod) and the suspension rope is zero after rotation, the alignment of the tooth structure and clearance between the shaft spline and spline sleeve is completed. Finally, the shaft spline and spline sleeve are pushed towards each other until they are engaged. This solution significantly improves the installation accuracy of the coupling.
[0007] The present invention provides a coupling installation device for a pump station, characterized in that it includes a clearance adjustment mechanism for aligning the shaft spline and the spline sleeve;
[0008] The clearance adjustment mechanism includes an annular gear sleeve for adjusting the clearance between the shaft spline and the spline sleeve, a rotating rod fixedly connected to the annular gear sleeve for driving the annular gear sleeve, a gripping assembly fixedly connected to the rotating rod for driving the rotating rod to rotate in the direction and angle, a suspension rope fixedly connected to the gripping assembly below the gripping assembly, and a suspension block fixedly installed at the lower end of the suspension rope.
[0009] The grip assembly includes a rotary handle fixedly connected to the rotary rod, and a marker rod vertically fixed below the rotary handle for indicating whether the shaft spline and spline sleeve are aligned;
[0010] A pair of first positioning holes are symmetrically opened on the annular toothed sleeve and the grip assembly. A pair of second positioning holes that are adapted to the first positioning holes are symmetrically opened at both ends of the rotating rod. The annular toothed sleeve, the rotating rod, and the rotating handle are fixedly connected by a pair of positioning rods set in the first positioning holes and the second positioning holes.
[0011] The horizontally protruding teeth of the annular gear sleeve are parallel to the positioning rod, and the positioning rod is perpendicular to the marker rod.
[0012] The above-mentioned pump station coupling installation device is characterized in that: the annular gear sleeve includes an outer gear sleeve that meshes with the shaft spline and an inner gear sleeve that meshes with the spline sleeve.
[0013] The beneficial effects are analyzed and reasoned as follows:
[0014] In the prior art, since both the spline sleeve and the shaft spline are installed manually, there is a situation where the spline sleeve and the shaft spline are not engaged when they are pushed in opposite directions (i.e., the coupling is not effectively connected to the motor and the oil pump). Furthermore, the misengagement and compression of the spline sleeve and the shaft spline can cause damage to the tooth structure of the spline sleeve and the shaft spline.
[0015] In the technical solution provided by this utility model, firstly, the annular gear sleeve is installed on the shaft spline or spline sleeve. Secondly, by rotating the rotating handle, the rotating rod and the annular gear sleeve, which are fixedly connected to the rotating handle, can rotate synchronously until the angle between the marker rod and the suspension rope is 0°, thus completing the alignment of the teeth and clearance of the shaft spline and spline sleeve. Finally, the motor shaft with the shaft spline and the pump input shaft with the spline sleeve are brought closer together to achieve the meshing of the shaft spline and spline sleeve, thereby realizing the installation of the coupling and achieving the purpose of connecting the motor and the oil pump using the coupling.
[0016] Firstly, before adjustment, because the horizontally protruding teeth of the annular gear sleeve are parallel to the positioning rod, and the positioning rod is perpendicular to the marker rod, the alignment of the teeth and clearance of the shaft spline and spline sleeve is achieved when the marker rod is parallel to the suspension rope.
[0017] Secondly, during adjustment, the inclusion of annular gear sleeves, rotating rods, rotating handles, marker rods, suspension ropes, and suspension blocks allows for alignment of the teeth and clearances of the shaft splines and spline sleeves, thereby greatly improving the installation accuracy of the coupling.
[0018] Therefore, the technical solution of this utility model greatly improves the installation accuracy of the coupling. Attached Figure Description

[0029] The present invention will now be described in further detail with reference to the embodiments and accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.
[0030] It should be noted that, where there is no conflict, the features of the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the embodiments and accompanying drawings.
[0031] In the existing technology, since both the spline sleeve and the shaft spline are installed manually, there is a situation where the spline sleeve and the shaft spline are not meshed when they are pushed in opposite directions (i.e., the coupling is not effectively connected to the motor and the oil pump). When the spline sleeve and the shaft spline are not meshed, the squeezing between them will cause damage to the tooth structure of the spline sleeve and the shaft spline.
[0032] Based on this, the present invention provides a coupling installation device for pump stations. Firstly, the rotation direction and angle of the annular gear sleeve can be controlled using a gripping component (specifically, a rotating handle), thereby synchronously controlling the rotation direction and angle of the shaft spline and spline sleeve. Secondly, when the angle between the gripping component (specifically, a marker rod) and the suspension rope is zero after rotation, the alignment of the tooth structure and clearance between the shaft spline and spline sleeve is completed. Finally, the shaft spline and spline sleeve are pushed towards each other until they are engaged. This greatly improves the installation accuracy of connecting the motor and the oil pump using the coupling.

[0034] Combination Figures 1 to 6 The present invention provides a coupling installation device for a pump station, comprising: a clearance adjustment mechanism for aligning the shaft spline 1 and the spline sleeve 2;
[0035] The clearance adjustment mechanism includes an annular toothed sleeve for adjusting the clearance between the shaft spline 1 and the spline sleeve 2, a rotating rod 3 fixedly connected to the annular toothed sleeve for driving the annular toothed sleeve, a gripping assembly fixedly connected to the rotating rod 3 for driving the rotating rod 3 to rotate in the direction and angle, a suspension rope 4 fixedly connected to the gripping assembly and disposed below the gripping assembly, and a suspension block 5 fixedly disposed at the lower end of the suspension rope 4.
[0036] The grip assembly includes a rotating handle 6 fixedly connected to the rotating rod 3, and a marker rod 7 vertically fixed below the rotating handle 6 for indicating whether the shaft spline 1 and spline sleeve 2 are aligned.
[0037] A pair of first positioning holes are symmetrically opened on the annular toothed sleeve and the grip assembly. A pair of second positioning holes adapted to the first positioning holes are symmetrically opened at both ends of the rotating rod. The annular toothed sleeve, the rotating rod 3, and the rotating handle 6 are fixedly connected by a pair of positioning rods 10 set in the first positioning hole and the second positioning hole.
[0038] The horizontally protruding teeth of the annular gear sleeve are parallel to the positioning rod 10, and the positioning rod 10 is perpendicular to the marker rod 7.
[0039] The coupling includes a shaft spline 1 and a spline sleeve 2. Both the shaft spline 1 and the spline sleeve 2 are annular tooth structures. When in use, the two mesh together as a connecting component between the motor and the oil pump.
[0040] It is understandable that the teeth of the shaft spline 1 face outwards, while the teeth of the spline sleeve 2 face inwards.
[0041] Suspension block 5 ensures that suspension rope 4 always hangs vertically downwards.
[0042] In practice, firstly, the direction and angle of the shaft spline 1 can be adjusted. For example, firstly, the shaft spline 1 is installed on the outer circumference of the motor shaft. Secondly, the annular toothed sleeve is set on the outer circumference of the shaft spline 1. Thirdly, the shaft spline 1 is adjusted by rotating the handle 6 until the included angle between the marker rod 7 and the suspension rope 4 is 0°.
[0043] Secondly, the direction and angle of the spline sleeve 2 can be adjusted. For example, firstly, install the spline sleeve 2 on the outer circumference of the pump input shaft. Secondly, set the annular gear sleeve on the inner circumference of the spline sleeve 2. Thirdly, rotate the handle 6 until the angle between the marker rod 7 and the suspension rope 4 is 0°, thus adjusting the spline sleeve 2.
[0044] Finally, the motor shaft with the outer spline 1 and the pump input shaft with the outer spline sleeve 2 are pushed towards each other. Since the teeth and clearance of the shaft spline 1 and the spline sleeve 2 have been aligned in the aforementioned steps, the shaft spline 1 and the spline sleeve 2 can be accurately meshed, thus completing the purpose of installing a coupling between the motor and the oil pump.
[0045] The beneficial effects are analyzed and reasoned as follows:
[0046] In the prior art, since both the spline sleeve and the shaft spline are installed manually, there is a situation where the spline sleeve and the shaft spline are not engaged when they are pushed in opposite directions (i.e., the coupling is not effectively connected to the motor and the oil pump). Furthermore, the misengagement and compression of the spline sleeve and the shaft spline can cause damage to the tooth structure of the spline sleeve and the shaft spline.
[0047] In the technical solution provided by this utility model, firstly, the annular gear sleeve is installed on the shaft spline 1 or the spline sleeve 2. Secondly, by rotating the rotating handle 6, the rotating rod 3 and the annular gear sleeve, which are fixedly connected to the rotating handle 6, can rotate synchronously until the angle between the marker rod 7 and the suspension rope 4 is 0°, thus completing the alignment of the teeth and clearances of the shaft spline 1 and the spline sleeve 2. Finally, the motor shaft with the shaft spline 1 and the pump input shaft with the spline sleeve 2 are brought closer together to achieve the meshing of the shaft spline 1 and the spline sleeve 2, thereby realizing the installation of the coupling and achieving the purpose of connecting the motor and the oil pump using the coupling.
[0048] Firstly, before adjustment, because the horizontally protruding teeth of the annular gear sleeve are parallel to the positioning rod 10, and the positioning rod 10 is perpendicular to the marker rod 7, the alignment of the teeth and clearance of the shaft spline 1 and spline sleeve 2 is achieved when the marker rod 7 is parallel to the suspension rope 4.
[0049] Secondly, during adjustment, the presence of the annular gear sleeve, rotating rod 3, rotating handle 6, marker rod 7, suspension rope 4, and suspension block 5 enables alignment of the teeth and clearances of the shaft spline 1 and spline sleeve 2, thereby greatly improving the installation accuracy of the coupling.
[0050] Therefore, the technical solution of this utility model greatly improves the installation accuracy of the coupling.
[0051] The embodiments described above introduce a coupling installation device for pump stations. In another embodiment of this utility model, the specific structure of the annular gear sleeve is described.
[0052] For example, the annular gear sleeve includes an outer gear sleeve 8 that meshes with the shaft spline 1 and an inner gear sleeve 9 that meshes with the spline sleeve 2.
[0053] It is understandable that when adjusting the rotation of the shaft spline 1 and spline sleeve 2, each of the shaft spline 1 and spline sleeve 2 has its corresponding toothed sleeve structure.
[0054] In practice, when adjusting the rotation of the shaft spline 1, an external gear sleeve 8 can be installed on the outside of the shaft spline 1. Similarly, when adjusting the rotation of the spline sleeve 2, an internal gear sleeve 9 can be installed on the inside of the spline sleeve 2.
[0055] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0056] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
