A high-pressure water pump casing removal device Technical Field

[0001] This utility model relates to the technical field of water pump sleeve maintenance equipment, and in particular to a high-pressure water pump sleeve removal device. Background Technology

[0002] During the maintenance and repair of high-pressure water pumps, it is often necessary to replace or overhaul the mechanical seal components.

[0003] However, in the current technology, most water pump maintenance is done by manually disassembling and repairing internal parts such as the volute and the sealing sleeve. However, since the sealing sleeve is usually installed on the pump shaft and is in a high-pressure environment, direct disassembly may cause damage or make operation difficult, so a solution is needed. Summary of the Invention

[0004] The purpose of this utility model is to solve the problem that exists in the prior art: most water pump maintenance is currently carried out by manually disassembling and repairing internal parts, such as the volute and the seal. However, since the seal is usually installed on the pump shaft and is in a high-pressure environment, direct disassembly may cause damage or operational difficulties.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a high-pressure water pump casing removal device, comprising: a base; multiple casters disposed at the four corners of one side surface of the base; and further comprising:

[0006] A support frame is disposed on the surface of the base, and a guide rod is fixedly disposed on the inner wall of the support frame;

[0007] A drive motor is mounted on the surface of a support frame via a frame body. The output end of the drive motor is provided with a threaded rod. A U-shaped frame is threadedly fitted on the outer surface of the threaded rod. One end of the U-shaped frame is movably fitted on the surface of a guide rod. A guide rod is fixedly provided on the inner wall of the U-shaped frame.

[0008] The second drive motor is mounted on the surface of the U-shaped frame via a frame body. The output end of the second drive motor is provided with a threaded rod, and a movable plate is threadedly fitted onto the outer surface of the threaded rod.

[0009] Preferably, the movable plate is slidably sleeved on the surface of the guide rod two, and the surface of the movable plate is provided with a ring.

[0010] The technical effect of adopting the above-mentioned further solution is that the guide rods provide limiting for the moving plate, while the moving plate provides fixing for the ring.

[0011] Preferably, the surface of the ring is provided with multiple slots, and a positioning shaft is fixedly installed inside the multiple slots.

[0012] The technical effect of adopting the above-mentioned further solution is that the groove opened on the surface of the ring provides a fixing function for the positioning shaft.

[0013] Preferably, the outer surface bearings of the plurality of positioning shafts are fitted with grippers, and one side surface of the plurality of grippers is provided with an anti-slip pad.

[0014] The technical effect of adopting the above-mentioned further solution is that the positioning is achieved by the grippers on a pair of surfaces through the positioning shaft, and the anti-slip pads on the gripper surfaces facilitate anti-slip operation.

[0015] Preferably, a positioning shaft is fixedly provided on the inner wall of one end of the plurality of grippers, and a hydraulic cylinder is provided on one side surface of the moving plate.

[0016] The technical effect of adopting the above-mentioned further solution is that the gripper provides positioning for the second positioning shaft, while the moving plate supports the hydraulic cylinder.

[0017] Preferably, the output end of the hydraulic cylinder is provided with a disc, and the inner wall of the disc is provided with multiple positioning shafts.

[0018] The technical effect of adopting the above-mentioned further solution is that when the hydraulic cylinder works, it drives the output end disc to move, so that the positioning shaft three on the inner wall can move.

[0019] Preferably, the outer surfaces of the multiple positioning shafts three are fitted with connecting rods, and one end of the multiple connecting rods is fitted with a bearing on the surface of the positioning shaft two.

[0020] The technical effect of adopting the above-mentioned further solution is that the positioning work is provided by the three pairs of connecting rods of the positioning shaft, and the gripper is deflected with the positioning shaft as the fixed point by one end of the connecting rod sleeved on the surface of the second positioning shaft.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] 1. In this utility model, when the first drive motor is started, the first output threaded rod drives the U-shaped frame to adjust its height along the first guide rod. At the same time, when the second drive motor is started, the second output threaded rod drives the moving plate to move laterally along the surface of the second guide rod. Because the positions of the pump casing structure are different at different locations, it is convenient to disassemble pumps of different sizes, thus improving the applicability of the device.

[0023] 2. In this utility model, when the hydraulic cylinder is started, the disc drives the positioning shaft three to move. With the help of one end of the connecting rod, it is sleeved on the surface of the positioning shaft two, allowing the grippers to deflect along the positioning shaft one, so that multiple grippers unfold. When the anti-slip pad contacts the water pump cover, the hydraulic cylinder is started again to reset, completing the fixing of the water pump cover. With the movement of the drive motor two, the removal work is completed. No manual disassembly is required, reducing damage to parts and improving work efficiency. Attached Figure Description

[0030] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0031] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0032] Example 1, as shown in Figures 1-4, provides a high-pressure water pump casing removal device, including: a base 1; multiple casters 101, disposed at the four corners of one side surface of the base 1; and further including: a support frame 102, disposed on the surface of the base 1, with a guide rod 1021 fixedly disposed on the inner wall of the support frame 102; a drive motor 103, disposed on the surface of the support frame 102 via a frame body, with a threaded rod 1031 disposed at the output end of the drive motor 103, a U-shaped frame 1032 threadedly fitted on the outer surface of the threaded rod 1031, one end of the U-shaped frame 1032 movably fitted on the surface of the guide rod 1021, and a guide rod 2 1033 fixedly disposed on the inner wall of the U-shaped frame 1032; and a drive motor 2 104, disposed on the surface of the U-shaped frame 1032 via a frame body, with a threaded rod 2 1041 disposed at the output end of the drive motor 2 104, and a movable plate 1042 threadedly fitted on the outer surface of the threaded rod 2 1041.

[0033] In this embodiment, when the drive motor 103 is started, the output threaded rod 1031 drives the U-shaped frame 1032 to adjust its height along the guide rod 1021. At the same time, when the drive motor 104 is started, the output threaded rod 1041 drives the moving plate 1042 to move laterally along the surface of the guide rod 1033. Since the positions of the pump casing structure are different at different locations, it is convenient to disassemble pumps of different sizes, thus improving the applicability of the device.

[0034] In Example 2, the movable plate 1042 is slidably sleeved on the surface of the guide rod 1033. The surface of the movable plate 1042 is provided with a ring 1043. The surface of the ring 1043 is provided with multiple slots 1044. The interior of the multiple slots 1044 is fixedly provided with a positioning shaft 1045. The outer surface of the multiple positioning shafts 1045 is bearing-sleeved with a gripper 1046. One side surface of the multiple grippers 1046 is provided with an anti-slip pad 1047. The inner wall of one end of the multiple grippers 1046 is fixedly provided with a positioning shaft 2 1048. One side surface of the movable plate 1042 is provided with a hydraulic cylinder 105. The output end of the hydraulic cylinder 105 is provided with a disc 1051. The inner wall of the disc 1051 is provided with multiple positioning shafts 3 1052. The outer surface of the multiple positioning shafts 3 1052 is bearing-sleeved with a connecting rod 1053. One end of the multiple connecting rods 1053 is bearing-sleeved on the surface of the positioning shaft 2 1048.

[0035] In this embodiment, when the hydraulic cylinder 105 is activated, the disc 1051 drives the positioning shaft 1052 to move. With the help of one end of the connecting rod 1053, which is sleeved on the surface of the positioning shaft 1048, the grippers 1046 deflect along the positioning shaft 1045, causing the multiple grippers 1046 to unfold. When the anti-slip pad 1047 contacts the water pump cover, the hydraulic cylinder 105 is activated again to reset, completing the fixing of the water pump cover. With the help of the drive motor 104, the removal is completed. No manual disassembly is required, reducing damage to parts and improving work efficiency.

[0036] Working Principle: During use, the pump moves via casters 101 and is positioned using a brake device. Depending on the pump size, starting drive motor 103 causes the output threaded rod 1031 to move the U-shaped frame 1032 along guide rod 1021, adjusting its height. Simultaneously, starting drive motor 104 causes the output threaded rod 1041 to move the moving plate 1042 laterally along guide rod 1033. Because the pump casing positions vary at different locations, this facilitates disassembly of pumps of different sizes, improving the overall performance of the device. In terms of applicability, when the hydraulic cylinder 105 is activated, the disc 1051 drives the positioning shaft 1052 to move. With the help of one end of the connecting rod 1053, which is sleeved on the surface of the positioning shaft 1048, the grippers 1046 deflect along the positioning shaft 1045, causing the multiple grippers 1046 to unfold. When the anti-slip pad 1047 contacts the water pump cover, the hydraulic cylinder 105 is activated again to reset, completing the fixing of the water pump cover. With the help of the drive motor 104, the removal is completed. No manual disassembly is required, reducing damage to parts and improving work efficiency.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
