Description

Technical Field

[0001] This utility model relates to the field of testing bench technology, specifically a special testing bench for slurry pump fault detection. Background Technology

[0002] Slurry pumps are key equipment in industries such as mining, metallurgy, power, and coal for transporting liquids containing solid particles. Their operating conditions are complex, making them prone to failure. Regular inspection and maintenance of slurry pumps are crucial for ensuring stable operation, reducing equipment failure rates, and extending their service life.

[0003] In the daily inspection and maintenance of slurry pumps, it is usually necessary to use clamps to fix them on the test bench. However, the existing clamps have a relatively simple function, which can only achieve simple fixation of the slurry pump. Once it is necessary to change the angle or position of the slurry pump during the maintenance process to check the fault conditions of different parts, the slurry pump must be removed from the clamp and then re-fixed. The whole process is cumbersome and time-consuming, which greatly reduces the efficiency of fault detection.

[0004] It is evident that existing technologies suffer from low efficiency in fault detection of slurry pumps. Utility Model Content

[0005] The purpose of this invention is to provide a special test bench for slurry pump fault detection, so as to solve the problem of low efficiency in the existing technology when detecting faults in slurry pumps.

[0006] This utility model provides a special test bench for slurry pump fault detection, including a test bench, an adjustment mechanism and a clamping mechanism. The adjustment mechanism includes a first adjustment plate, a sliding sleeve, a second adjustment plate and a rotating platform. The first adjustment plate is disposed on the test bench and is connected to the second adjustment plate through the sliding sleeve. The sliding sleeve is a sleeve structure with adjustable length. The rotating platform is disposed on the second adjustment plate.

[0007] The clamping mechanism includes a clamping seat and clamping rods. The clamping seat is rotatably connected to the second adjusting plate via the rotating platform. The clamping seat extends away from the rotating platform to form a groove structure with a receiving cavity. The receiving cavity is used to place the slurry pump. A pair of clamping rods are disposed on the clamping seat at a position away from the rotating platform, and the pair of clamping rods are disposed opposite to each other facing the receiving cavity.

[0008] Optionally, the adjustment mechanism further includes a fixed seat, a bidirectional screw, a slider, and a hinge structure disposed between the first adjustment plate and the second adjustment plate. A pair of fixed seats are disposed on the first adjustment plate, the bidirectional screw is disposed between the pair of fixed seats and is rotatably connected to the fixed seats, a pair of sliders are respectively disposed at both ends of the bidirectional screw and are threadedly connected to the bidirectional screw, and each slider is connected to the second adjustment plate through a hinge structure.

[0009] When the bidirectional screw rotates, it drives a pair of sliders to slide towards or away from each other on the bidirectional screw. When the pair of sliders slide towards each other, the distance between the first adjusting plate and the second adjusting plate increases.

[0010] Optionally, one of the pair of fixed seats is provided with a rocker arm or a drive motor, the rocker arm being connected to one end of the bidirectional screw, or the output shaft of the drive motor being connected to one end of the bidirectional screw.

[0011] Optionally, when the rocker arm is provided on the fixed base, the fixed base on which the rocker arm is provided includes a first synchronous pulley, a belt and a second synchronous pulley. The first synchronous pulley is connected to the rocker arm and the second synchronous pulley is connected to one end of the bidirectional screw. The first synchronous pulley is rotatably connected to the second synchronous pulley through the belt.

[0012] Optionally, the clamping rod includes an adjusting rod, a moving rod, and a clamping block. The adjusting rod is sleeved and connected to the moving rod. The adjusting rod is disposed on the clamping seat. The moving rod at least partially overlaps with the adjusting rod. The clamping block is disposed on the moving rod at one end away from the adjusting rod.

[0013] Specifically, when the moving rod rotates in the forward direction, it causes the clamping block to move toward the receiving cavity; when the moving rod rotates in the reverse direction, it causes the clamping block to move away from the receiving cavity.

[0014] Optionally, the clamping rod further includes a first servo motor and a screw connected to the output shaft of the first servo motor. The first servo motor is disposed inside the adjusting rod, the screw extends along the length direction of the adjusting rod, and a screw hole is provided at the end of the moving rod away from the clamping block. The moving rod is rotatably connected to the screw through the screw hole.

[0015] When the first servo motor drives the screw to rotate, the screw drives the moving rod to rotate in the forward or reverse direction.

[0016] Optionally, the rotating table includes a first slip ring and a second slip ring, the first slip ring and the second slip ring are sleeved together, one end of the first slip ring is located at the center of the second adjusting plate, and the other end of the first slip ring is rotatably connected to the clamping seat through the second slip ring.

[0017] Optionally, the rotary table further includes a second servo motor, which is disposed inside the first slip ring, and the output shaft of the second servo motor is connected to the second slip ring.

[0018] Optionally, the sliding sleeves are arranged in an array between the first adjusting plate and the second adjusting plate.

[0019] Optionally, the experimental platform is also provided with a hanging plate, and a light panel is installed on the upper end of the hanging plate. The control button of the light panel is located on the experimental platform near the adjustment mechanism.

[0020] In this embodiment of the invention, the test bench provides an operating platform for the entire slurry pump fault detection process. In the adjustment mechanism, the first adjustment plate is connected to the second adjustment plate via an adjustable-length sliding sleeve, allowing for flexible adjustment of the distance between the two plates, thus achieving height adjustment. The second adjustment plate is connected to the clamping seat of the clamping mechanism via a rotating platform. The rotation of the rotating platform drives the rotation of the clamping mechanism, thereby achieving angle adjustment. The accommodating cavity formed by the extension of the clamping seat can hold the slurry pump to be tested, and the clamping rods on the clamping seat clamp and fix the slurry pump to be tested, reducing the likelihood of the slurry pump slipping out of the clamping mechanism during testing. Furthermore, a pair of clamping rods are arranged opposite each other towards the accommodating cavity. Through the extension and retraction of the clamping rods, it is possible to adapt to the fixing of slurry pumps of different sizes and to adapt to clamping the same slurry pump from different directions. In this way, the slurry pump to be tested is placed in the receiving cavity of the clamping seat and fixed by the clamping rod. The height between the slurry pump and the test platform can be adjusted by the adjusting plate to adapt to the testing of different parts of the slurry pump in the height direction. The rotation angle of the clamping mechanism can be adjusted by the rotating table to adapt to the testing of different parts of the slurry pump in the circumferential direction. In the fault detection process, there is no need to repeatedly disassemble and assemble the slurry pump, which improves the testing efficiency. Attached Figure Description

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0030] The terms "first," "second," etc., used in the specification and claims of this utility model are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such usage can be interchanged where appropriate so that embodiments of this utility model can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, the first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0031] like Figures 1 to 6 As shown, this utility model embodiment provides a special test bench for slurry pump fault detection, including a test bench 10, an adjustment mechanism 20 and a clamping mechanism 30. The adjustment mechanism 20 includes a first adjustment plate 201, a sliding sleeve 202, a second adjustment plate 203 and a rotating platform 204. The first adjustment plate 201 is disposed on the test bench 10 and is connected to the second adjustment plate 203 through the sliding sleeve 202. The sliding sleeve 202 is a sleeve structure with adjustable length. The rotating platform 204 is disposed on the second adjustment plate 203.

[0032] The clamping mechanism 30 includes a clamping seat 301 and clamping rods 302. The clamping seat 301 is rotatably connected to the second adjusting plate 203 via a rotating table 204. The clamping seat 301 extends away from the rotating table 204 to form a groove structure with a receiving cavity. The receiving cavity is used to place the slurry pump. A pair of clamping rods 302 are arranged on the clamping seat 301 at a position away from the rotating table 204, and the pair of clamping rods 302 are arranged opposite to each other towards the receiving cavity.

[0033] In this embodiment of the invention, the experimental platform 10 provides an operating platform for the entire slurry pump fault detection; in the adjustment mechanism 20, the first adjustment plate 201 is connected to the second adjustment plate 203 through an adjustable sliding sleeve 202, which can flexibly adjust the interval between the first adjustment plate 201 and the second adjustment plate 203, thereby achieving height adjustment; the second adjustment plate 203 is connected to the clamping seat 301 of the clamping mechanism 30 through a rotating table 204, and the rotation of the rotating table 204 can drive the rotation of the clamping mechanism 30, from The angle can be adjusted; the accommodating cavity formed by the extension of the clamping seat 301 can hold the slurry pump to be tested, and the clamping rod 302 set on the clamping seat 301 clamps and fixes the slurry pump to be tested, reducing the possibility of the slurry pump slipping out of the clamping mechanism 30 during the test; in addition, a pair of clamping rods 302 are arranged opposite to each other towards the accommodating cavity, and the extension and retraction movement of the clamping rods 302 can adapt to the fixation of slurry pumps of different sizes, and can adapt to the clamping of the same slurry pump from different directions. In this way, the slurry pump to be tested is placed in the accommodating cavity of the clamping seat 301 and fixed by the clamping rods 302. The height between the slurry pump and the test platform 10 can be adjusted by the adjusting plate to adapt to the test of different parts of the slurry pump in the height direction; the rotation angle of the clamping mechanism 30 can be adjusted by the rotating table 204 to adapt to the test of different parts of the slurry pump in the circumferential direction. During the fault detection process, there is no need to repeatedly disassemble and assemble the slurry pump, improving the detection efficiency.

[0034] Optionally, the adjustment mechanism 20 further includes a fixed seat 205, a bidirectional screw 206, a slider 207, and a hinge structure 208 disposed between the first adjustment plate 201 and the second adjustment plate 203. A pair of fixed seats 205 are disposed on the first adjustment plate 201, the bidirectional screw 206 is disposed between the pair of fixed seats 205 and is rotatably connected to the fixed seats 205, a pair of sliders 207 are respectively disposed at both ends of the bidirectional screw 206 and are threadedly connected to the bidirectional screw 206, and each slider 207 is connected to the second adjustment plate 203 through a hinge structure 208.

[0035] When the bidirectional screw 206 rotates, it drives a pair of sliders 207 to slide towards each other or away from each other on the bidirectional screw 206. When the pair of sliders 207 slide towards each other, the distance between the first adjusting plate 201 and the second adjusting plate 203 increases. When the pair of sliders 207 slide away from each other, the distance between the first adjusting plate 201 and the second adjusting plate 203 decreases.

[0036] In this example, the hinge structure 208 may include a connecting rod and mounting seats at both ends of the connecting rod. The connecting rod is connected to the slider 207 and the second adjusting plate 203 respectively through the mounting seats movably connected at both ends, so that the slider 207 and the second adjusting plate 203 are hinged together, which facilitates height adjustment. In this way, the fixed seat 205, the bidirectional screw 206, the slider 207 and the hinge structure 208 in the adjusting mechanism 20 cooperate, and the threads at both ends of the bidirectional screw 206 are opposite in direction. When the bidirectional screw 206 rotates, the sliders 207 at both ends of the bidirectional screw 206 can slide towards each other or away from each other on the bidirectional screw 206 under the drive of the threads. The sliding of the sliders 207 drives the movement of the hinge structure 208, thereby changing the distance between the first adjusting plate 201 and the second adjusting plate 203, adjusting the height between the slurry pump and the test platform 10, realizing the detection of different parts of the slurry pump in the height direction. In the fault detection process, there is no need to repeatedly disassemble and assemble the slurry pump, which improves the detection efficiency.

[0037] Optionally, either of the pair of fixed seats 205 is provided with a rocker arm 209 or a drive motor, the rocker arm 209 being connected to one end of the bidirectional screw 206, or the output shaft of the drive motor being connected to one end of the bidirectional screw 206.

[0038] In this example, a rocker arm 209 or a drive motor is provided on the fixed base 205. The rocker arm 209 can be manually operated or the power of the drive motor can be used to drive the bidirectional screw 206 to rotate, providing a power source for adjusting the distance between the first adjustment plate 201 and the second adjustment plate 203, so that the operator can choose the appropriate adjustment method according to the actual situation.

[0039] Optionally, when a rocker arm 209 is provided on the fixed base 205, the fixed base 205 with the rocker arm 209 includes a first synchronous pulley 2051, a belt 2052 and a second synchronous pulley 2053. The first synchronous pulley 2051 is connected to the rocker arm 209, and the second synchronous pulley 2053 is connected to one end of the bidirectional screw 206. The first synchronous pulley 2051 is rotatably connected to the second synchronous pulley 2053 through the belt 2052.

[0040] In this example, a rocker arm 209 can be used to achieve fine adjustment. By rotating the rocker arm 209, the first synchronous wheel 2051 connected to the rocker arm 209 rotates. The first synchronous wheel 2051 drives the second synchronous wheel 2053 to rotate via the belt 2052, thereby driving the bidirectional screw 206. Thus, when the bidirectional screw 206 rotates, the sliders 207 at both ends of the bidirectional screw 206 can slide towards or away from each other on the bidirectional screw 206 under the influence of the screw thread. The sliding of the sliders 207 in turn drives the hinge structure 208 to move, thereby changing the distance between the first adjusting plate 201 and the second adjusting plate 203, adjusting the height between the slurry pump and the experimental platform 10, and enabling the detection of different parts of the slurry pump in the height direction. During fault detection, there is no need to repeatedly disassemble and reassemble the slurry pump, improving detection efficiency.

[0041] Differential discs can be installed on the first synchronous pulley 2051 and the second synchronous pulley 2053, allowing differential speed adjustment as the first synchronous pulley 2051 drives the second synchronous pulley 2053 to rotate via a belt. For example, rotating the rocker arm 209 one revolution can drive the bidirectional screw 206 to rotate two revolutions, thus improving the efficiency of height adjustment.

[0042] Optionally, the clamping rod 302 includes an adjusting rod 3021, a moving rod 3022, and a clamping block 3023. The adjusting rod 3021 and the moving rod 3022 are sleeved and connected. The adjusting rod 3021 is disposed on the clamping seat 301. The moving rod 3022 at least partially overlaps with the adjusting rod 3021. The clamping block 3023 is disposed on the moving rod 3022 at one end away from the adjusting rod 3021.

[0043] Specifically, when the moving rod 3022 rotates in the forward direction, the moving rod 3022 drives the clamping block 3023 to move toward the receiving cavity; when the moving rod 3022 rotates in the reverse direction, the moving rod 3022 drives the clamping block 3023 to move away from the receiving cavity.

[0044] In this example, the adjusting rod 3021, the moving rod 3022, and the clamping block 3023 of the clamping rod 302 cooperate to clamp and fix the slurry pump to be tested, which is placed in the clamping seat 301, by adjusting the overlap length between the moving rod 3022 and the adjusting rod 3021. Specifically, the outer wall of the moving rod 3022 and the inner wall of the adjusting rod 3021 can be connected by threads. When the moving rod 3022 rotates in the forward direction, its nesting relationship with the adjusting rod 3021 converts the rotational motion into the linear displacement of the moving rod 3022, driving the moving rod 3022 to slide along the axial direction of the adjusting rod 3021, and causing the clamping block 3023 at the end to move towards the receiving cavity until it clamps the slurry pump to be tested; conversely, rotating the moving rod 3022 in the reverse direction causes it to move the clamping block 3023 away from the receiving cavity, releasing the clamping state. The entire process involves a linkage mechanism that uses the adjusting rod 3021 for fixed support, the moving rod 3022 for rotational transmission, and the clamping block 3023 for clamping action to complete the clamping and releasing of the object. This allows for the use of a pair of clamping rods 302 facing each other towards the receiving cavity, and the extension and retraction of the clamping rods 302 to accommodate the fixing of slurry pumps of different sizes, as well as the clamping of the same slurry pump from different directions. This improves the flexibility and applicability of the clamping process.

[0045] Optionally, the clamping rod 302 further includes a first servo motor 3024 and a screw 3025 connected to the output shaft of the first servo motor 3024. The first servo motor 3024 is disposed inside the adjusting rod 3021. The screw 3025 extends along the length of the adjusting rod 3021. A screw hole is provided at one end of the moving rod 3022 away from the clamping block 3023. The moving rod 3022 is rotatably connected to the screw 3025 through the screw hole.

[0046] When the first servo motor 3024 drives the screw 3025 to rotate, the screw 3025 drives the moving rod 3022 to rotate in the forward or reverse direction.

[0047] In this example, the first servo motor 3024, screw 3025, moving rod 3022, and clamping block 3023 work together to achieve this. When it is necessary to fix the grout pump to be tested, the first servo motor 3024 starts and drives the screw 3025 to rotate forward. Since the moving rod 3022 is rotatably connected to the screw 3025 through a screw hole, the forward rotation of the screw 3025 will drive the moving rod 3022 to rotate forward. The moving rod 3022 is sleeved and connected to the adjusting rod 3021. Its forward rotation causes the moving rod 3022 to move towards the receiving cavity along the length direction of the adjusting rod 3021, thereby driving the clamping block 3023, which is set on the moving rod 3022 at the end away from the adjusting rod 3021, to move towards the receiving cavity until the grout pump to be tested is clamped. When release is required, the first servo motor 3024 drives the screw 3025 to rotate in the opposite direction, which in turn drives the moving rod 3022 to rotate in the opposite direction. This causes the moving rod 3022 to move the clamping block 3023 away from the receiving cavity, thereby releasing the clamp on the object. The telescopic movement of the clamping rod 302 adapts to the fixing of slurry pumps of different sizes and can accommodate clamping the same slurry pump from different directions. This improves the flexibility and applicability of the clamping mechanism and increases the efficiency of the clamping operation.

[0048] Optionally, the rotating table 204 includes a first slip ring 2041 and a second slip ring 2042. The first slip ring 2041 and the second slip ring 2042 are sleeved and connected. One end of the first slip ring 2041 is located at the center of the second adjusting plate 203, and the other end of the first slip ring 2041 is rotatably connected to the clamping seat 301 through the second slip ring 2042.

[0049] In this example, one end of the first slip ring 2041 is fixed at the center of the second adjusting plate 203, providing a stable support point, while the other end is connected to the second slip ring 2042, which in turn is rotatably connected to the clamping seat 301. When it is necessary to adjust the rotation angle of the clamping seat 301, the second slip ring 2042 can rotate relative to the first slip ring 2041. Since the first slip ring 2041 is fixed on the second adjusting plate 203, this rotation will cause the clamping seat 301 connected to it to rotate around the axis of the first slip ring 2041, thereby realizing the flexible adjustment of the rotation angle of the clamping seat 301. In this way, the slurry pump to be tested is placed in the receiving cavity of the clamping seat 301 and fixed by the clamping rod 302. The height between the slurry pump and the test platform 10 can be adjusted by the adjusting plate to adapt to the testing of different parts of the slurry pump in the height direction. The rotation angle of the clamping mechanism 30 can be adjusted by the rotating table 204, so as to facilitate the adjustment of the angle of the slurry pump to adapt to the testing of different parts of the slurry pump in the circumferential direction. In the fault detection process, there is no need to repeatedly disassemble and assemble the slurry pump, thus improving the testing efficiency.

[0050] Optionally, the rotary table 204 also includes a second servo motor 2043, which is disposed inside the first slip ring 2041, and the output shaft of the second servo motor 2043 is connected to the second slip ring 2042.

[0051] In this example, the rotation angle adjustment of the turntable 204 is achieved through the coordinated operation of the second servo motor 2043, the first slip ring 2041, and the second slip ring 2042. The second servo motor 2043 is located inside the first slip ring 2041, and its output shaft is connected to the second slip ring 2042. When the rotation angle needs to be adjusted, the second servo motor 2043 is started, and its output shaft drives the second slip ring 2042 to rotate. Since the first slip ring 2041 and the second slip ring 2042 are sleeved together and the first slip ring 2041 is fixed, the second slip ring 2042 can perform circular motion relative to the first slip ring 2041. Furthermore, since the second slip ring 2042 is rotatably connected to the clamping seat 301, the rotation of the second slip ring 2042 will drive the clamping seat 301 to rotate around the axis of the first slip ring 2041. By precisely controlling the rotation direction and amount of the second servo motor 2043, the rotation angle of the clamping seat 301 can be precisely adjusted.

[0052] Optionally, the sliding sleeves 202 are arranged in an array between the first adjusting plate 201 and the second adjusting plate 203.

[0053] In this example, the sliding sleeves 202 are arranged in an array between the first adjusting plate 201 and the second adjusting plate 203, which can enhance the stability and load-bearing capacity of the adjusting mechanism 20 and ensure the stability of the entire structure during the height adjustment process.

[0054] Optionally, the experimental platform 10 is also provided with a hanging plate 40, and a lamp plate 50 is installed on the upper end of the hanging plate 40. The control button 501 of the lamp plate 50 is located on the experimental platform 10 near the adjustment mechanism 20.

[0055] In this example, a light panel 50 is installed on the mounting plate 40 on the experimental platform 10 to provide illumination for fault detection of the slurry pump. The control button 501 of the light panel 50 is located on the experimental platform 10 near the adjustment mechanism 20, which makes it convenient for the operator to control the lighting while adjusting the equipment, thus improving the convenience of operation.

[0056] Specifically, the working principle of this special test bench for slurry pump fault detection is as follows: When using the special test bench for slurry pump fault detection, first, place the test bench 10 in a suitable working area to build a stable operating platform for the entire detection operation. When it is necessary to adjust the height of the slurry pump, the operating method can be selected according to the actual needs. If a rocker arm 209 is installed on the fixed base 205, manually rotate the rocker arm 209. The rocker arm 209 drives the first synchronous wheel 2051 to rotate. Through the transmission of the belt 2052, the second synchronous wheel 2053 rotates accordingly, which in turn drives the bidirectional screw 206 to rotate. If a drive motor is installed on the fixed base 205, after the motor starts, its output shaft drives the bidirectional screw 206 to rotate. During the rotation of the bidirectional screw 206, the sliders 207 at both ends slide towards or away from each other. The distance between the first adjusting plate 201 and the second adjusting plate 203 is changed through the hinge structure 208. The length is adjustable. The sliding sleeve 202 of the section assists in completing the height adjustment. The array of sliding sleeves 202 ensures the stability of the adjustment process. When placing the slurry pump, it is placed into the receiving cavity of the clamping seat 301. If the position of the clamping block 3023 needs to be adjusted, the first servo motor 3024 is started, which drives the screw 3025 to rotate. The screw 3025 drives the moving rod 3022 to rotate, so as to achieve precise adjustment of the position of the clamping block 3023. If the detection angle of the slurry pump needs to be adjusted, it can be achieved through the rotating table 204. The second servo motor 2043 is started, which drives the second slip ring 2042 to rotate, thereby driving the clamping seat 301 to rotate automatically, so as to achieve precise adjustment of the detection angle of the slurry pump. During the detection process, the control button 501 of the lamp panel 50 near the adjustment mechanism 20 on the experimental platform 10 can be pressed to turn the lamp panel 50 on the hanging plate 40 on or off, providing sufficient lighting for the detection work and making it easier for the operator to observe the condition of the slurry pump.
