Description

Technical Field

[0001] This disclosure relates to the field of pump shaft measurement technology, and more specifically, to a pump shaft measurement support. Background Technology

[0002] Pump shafts are crucial components in core equipment used in industries such as power and coal mining. Therefore, measuring pump shaft parameters is of paramount importance. In related technologies, two V-blocks are typically used as fulcrums at both ends of the pump shaft for measurement, drawing, calculation, adjustment, and data processing. However, using V-blocks to support the pump shaft can lead to problems such as large pump shaft disc torque, large rotational inertia, and large shaft runout, which can easily cause measurement errors and make it difficult to guarantee the accuracy of the measurement data. Utility Model Content

[0003] The purpose of this disclosure is to provide a pump shaft measuring support that provides good accuracy when measuring pump shafts.

[0004] To achieve the above objectives, this disclosure provides a pump shaft measuring support, comprising: Base; A support frame, wherein the support frame is provided with a receiving space for placing the pump shaft, and at least two support frames are provided, wherein the at least two support frames are arranged at intervals along a first direction on the base; The rolling assembly is provided in multiple sets, with the axis direction being the first direction. The multiple sets of rolling assemblies are rotatably arranged between two support frames along the contour of the support frame for abutting against the pump shaft.

[0005] Optionally, the rolling assembly includes a plurality of rolling bearings arranged coaxially, and the outer wall of the rolling bearing protrudes from the edge of the support frame for abutting against the pump shaft.

[0006] Optionally, the length of the plurality of rolling bearings stacked along the first direction is not less than the spacing between two adjacent support frames.

[0007] Optionally, the support frame is provided with a group of connecting holes, the group of connecting holes including a plurality of connecting holes arranged along the contour of the support frame, the connecting holes extending along the first direction and penetrating the support frame, the connecting holes being used to insert the connecting shaft, the connecting shaft being used to cooperate with the rolling bearing to rotatably connect the rolling bearing between two adjacent support frames.

[0008] Optionally, the connection hole group is provided in multiple groups, and is spaced apart on the support frame along a second direction perpendicular to the first direction.

[0009] Optionally, the support frame is further provided with a fixing part, which is used to fix the connecting shaft to at least one of the support frames.

[0010] Optionally, the fixing part includes fixing holes and fixing members provided on the support frame and the connecting shaft. The fixing members are used to be inserted into the fixing holes on the support frame and the connecting shaft to fix the connecting shaft to the support frame.

[0011] Optionally, the support frame is V-shaped and includes a first extension frame and a second extension frame, with the ends of the first extension frame and the second extension frame close to each other being fixedly connected to the base.

[0012] Optionally, it also includes a braking assembly for limiting the movement of the pump shaft relative to the support frame.

[0013] Optionally, the braking assembly includes a brake frame, a brake element, and a brake spring. The brake frame is U-shaped, with its closed end abutting against the outer wall of the pump shaft and its open end penetrating the base. The brake element is sleeved on the open end of the brake frame penetrating the base and is used to adjust the distance between the closed end of the brake frame and the base. The brake spring is located between the base and the brake element, and its two ends abut against the end faces of the base and the brake element, respectively.

[0014] The advantages of this disclosure through the above technical solution are as follows: the pump shaft support of this disclosure, by setting a rolling component on the support frame, allows the pump shaft to abut against the rolling component after being placed on the support frame. This reduces the force required to rotate the pump shaft relative to the support frame when the pump shaft needs to be rotated for measurement. It transforms the sliding friction between the pump shaft and the support in related technologies into rolling friction, thereby avoiding the problem of large disc torque between the pump shaft and the support frame.

[0015] Other features and advantages of this disclosure will be described in detail in the following detailed description section. Attached Figure Description

Detailed Implementation

[0018] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0019] In this disclosure, unless otherwise stated, directional terms such as "upper," "lower," "higher," "lower," "top," and "bottom" generally refer to the orientation of the corresponding component or structure in the direction of gravity. "Inner" and "outer" refer to the inner and outer contours of the corresponding component. Furthermore, it should be noted that terms such as "first" and "second" are used to distinguish one element from another and do not indicate sequence or importance. Additionally, in the description with reference to the accompanying drawings, the same reference numerals in different drawings denote the same element. The above definitions are for explanation and illustration only and should not be construed as limiting this disclosure.

[0020] This disclosure relates to a pump shaft measuring support, which can avoid the problem of large disc torque between the pump shaft and the support when supporting the pump shaft, thus ensuring the accuracy of pump shaft measurement. See [link to relevant documentation]. Figure 1 and Figure 2The pump shaft measuring support disclosed herein includes a base 1, a support frame 2, and a rolling assembly 3. The base 1 forms the foundation of the support and can be rectangular or circular, providing an installation base for other components in the support. The support frame 2 has a receiving space for placing the pump shaft, and multiple sets of rolling assemblies are provided and spaced apart along a first direction on the base 1. The support frame 2 and the base 1 are fixedly connected by welding or bolting, or other connection methods known to those skilled in the art. The axis of the rolling assembly 3 is in the first direction, and multiple sets of rolling assemblies 3 are provided. The multiple sets of rolling assemblies 3 are rotatably arranged between two support frames 2 along the contour of the support frame 2. For example, when the support frame 2 is rectangular, the multiple sets of rolling assemblies 3 are arranged spaced apart along the rectangle. After the pump shaft is placed in the receiving space, the rolling assembly 3 can abut against the pump shaft, so that when the pump shaft needs to rotate during the measurement process, the rotation of the rolling assembly 3 can reduce the force required to rotate the pump shaft relative to the support frame 2, thereby avoiding the problem of large disc torque between the pump shaft and the support frame 2.

[0021] The pump shaft support disclosed herein uses a rolling component 3 on the support frame 2 to allow the pump shaft to abut against the rolling component 3 after being placed on the support frame 2. This reduces the force required to rotate the pump shaft relative to the support frame 2 when the pump shaft needs to be rotated for measurement. This converts the sliding friction between the pump shaft and the support in related technologies into rolling friction, thereby avoiding the problem of large disc torque between the pump shaft and the support frame 2.

[0022] In some embodiments of this disclosure, see Figure 1 and Figure 2 The rolling assembly 3 includes multiple rolling bearings 31, which are coaxially arranged, and the outer walls of the rolling bearings 31 protrude from the edge of the support frame 2 so that the outer walls of the rolling bearings 31 can abut against the pump shaft. By setting the rolling assembly 3 as rolling bearings 31, the relatively stable operation and low cost of rolling bearings 31 can be utilized to give the pump shaft measuring support of this disclosure high stability and low manufacturing cost. Of course, in other embodiments, the rolling assembly 3 may also include other rolling components, such as rolling wheels, depending on the actual situation, and this disclosure does not limit this.

[0023] In some embodiments of this disclosure, see Figure 1 and Figure 2The length of the multiple rolling bearings 31 stacked along the first direction is not less than the distance between two adjacent support frames 2. This arrangement ensures that the gap between the two support frames 2 can be completely filled by the rolling bearings 31. When the pump shaft is placed in the receiving space on the support frame 2, it ensures that the part of the pump shaft in the receiving space is in complete contact with the rolling bearings 31, so that the rolling bearings 31 and the pump shaft have the maximum contact area, which better reduces the force that drives the pump shaft to rotate, and avoids the entire rolling assembly 3 from being unable to effectively support the pump shaft if a single rolling bearing 31 in the rolling assembly 3 is damaged.

[0024] In some embodiments of this disclosure, see Figure 1 and Figure 3 The support frame 2 is provided with a connecting hole group 21, which includes multiple connecting holes 211 arranged along the contour of the support frame 2. The number of connecting holes 211 can be the same as the number of rolling components 3. The connecting holes 211 extend along a first direction and penetrate the support frame 2. When installing the rolling components 3 and the support frame 2, it can be done through a connecting shaft 212. The connecting shaft 212 can pass through the inner ring of the rolling bearing 31 and the connecting hole 211 to connect the rolling bearing 31 to the support frame 2. Furthermore, a longer connecting shaft 212 can connect all the rolling bearings 31 between adjacent support frames 2 to the support frame 2. Multiple connecting shafts 212 can connect all the rolling components 3 to the support frame 2. Of course, in other embodiments, the connection method between the rolling components 3 and the support frame 2 can also be other, depending on the actual situation. This disclosure does not limit this.

[0025] In some embodiments of this disclosure, see Figure 1 and Figure 3 Multiple sets of connecting hole groups 21 are provided, spaced apart on the support frame 2 along a second direction perpendicular to the first direction. By providing multiple sets of connecting hole groups 21, the positional relationship between the axis of the rolling assembly 3 and the support frame 2 can be easily adjusted. This allows operators to adjust the connection between the connecting shaft 212 and different connecting hole groups 21 during measurement, thereby changing the distance of the rolling bearing 31 protruding from the edge of the support frame 2, and thus better completing the contact and measurement of the pump shaft.

[0026] In some embodiments of this disclosure, see Figure 3 and Figure 4A fixing part 22 is also provided on the support frame 2. By providing the fixing part 22, the connecting shaft 212 can be fixedly connected to at least one support frame 2. This arrangement can ensure the stability of the connection between the connecting shaft 212 and the support frame 2, and avoid the situation where the rolling bearing 31 and the connecting shaft 212 rotate freely, which would increase the disc torque between the pump shaft and the rolling bearing 31 and thus affect the measurement of the pump shaft. Of course, in other embodiments, multiple fixing parts 22 can also be provided, so as to make the connection between the connecting shaft 212 and the support frame 2 more stable. The specific number can be determined according to the actual situation, and this disclosure does not limit it.

[0027] In some embodiments of this disclosure, see Figure 3 and Figure 4 The fixing part 22 includes fixing holes 221 and fixing members 222 provided on the support frame 2 and the connecting shaft 212. The fixing holes 221 can be located at the edge of the support frame 2 and the end of the connecting shaft 212 to facilitate fixing between the connecting shaft 212 and the support frame 2. When fixing the connecting shaft 212 and the support frame 2, the fixing member 222 can be inserted into the support frame 2 and the connecting shaft 212 through the fixing holes 221 to fix the support frame 2 and the connecting shaft 212.

[0028] Specifically, the fixing hole 221 can be a circular hole that penetrates the end face of the support frame 2 and extends into the length of the extension portion inside the support frame 2, and a circular hole that penetrates the connecting shaft 212. The fixing member 222 can be a cylindrical member. When making a fixed connection between the connecting shaft 212 and the support frame 2, the connecting shaft 212 can be aligned with the fixing hole 221 on the support frame 2, and then the end of the cylindrical member can be inserted into the bottom of the circular hole located inside the support frame 2, thereby completing the fixed connection between the support frame 2 and the connecting shaft 212. Of course, in other embodiments, the structure of the fixing part 22 can also be other, depending on the actual situation, and this disclosure does not limit it.

[0029] In some embodiments of this disclosure, see Figure 1 and Figure 2 The support frame 2 is V-shaped and includes a first extension frame 23 and a second extension frame 24. The ends of the first extension frame 23 and the second extension frame 24 that are close to each other are fixedly connected to the base 1. By setting the support frame 2 in a V-shape, the advantages of the V-shaped support frame 2 in terms of structural stability, load-bearing capacity, space utilization efficiency, and applicability can be utilized to improve the stability of the support frame 2 when supporting the pump shaft. Of course, in other embodiments, the shape of the support frame 2 can also be other, such as rectangular or trapezoidal, depending on the actual situation, and this disclosure does not limit it.

[0030] In some embodiments of this disclosure, see Figure 1 and Figure 2 The pump shaft measuring support disclosed herein also includes a braking assembly 4. The braking assembly 4 can restrict the rotation of the pump shaft relative to the support frame 2, so as to brake and ensure the accuracy of data measurement when the pump shaft needs to be kept stationary for the measurement of pump shaft data. The braking assembly 4 may include a brake frame 41, a brake element 42, and a brake spring 43. The brake frame 41 is U-shaped and is inverted on the pump shaft so that the closed end of the U-shape can abut against the outer wall of the pump shaft, and the open end directly passes through the base 1. The brake element 42 is sleeved on the open end of the brake frame 41 that passes through the base 1, and can adjust the distance between the closed end of the brake frame 41 and the base 1. For example, the open end of the brake frame 41 may be threaded, and the brake element 42 is a bolt. The distance between the closed end of the brake frame 41 and the base 1 can be adjusted by rotating the bolt relative to the thread.

[0031] When adjusting, if the pump shaft needs to be stationary, the distance between the closed end of the brake frame 41 and the base 1 can be reduced, and the contact force between the closed end of the brake frame 41 and the base 1 can be increased to restrict the rotation of the pump shaft. After the measurement is completed, the distance between the closed end of the brake frame 41 and the base 1 can be increased, and the contact force between the closed end of the brake frame 41 and the base 1 can be reduced to restore the rotation of the pump shaft. The brake spring 43 is located between the base 1 and the brake element 42. For example, it can be sleeved on the open end of the brake frame 41 to assist the brake element 42 in adjusting the distance between the brake frame 41 and the base 1.

[0032] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0033] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0034] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
