Description

Technical Field

[0001] This application belongs to the technical field of equipment maintenance platforms, and particularly relates to a lifting operation platform for repairing water pump motors. Background Art

[0002] A water pump is an important mechanical equipment in a water conveyance system. However, due to the long-term poor working environment of the water pump, accidents of motor burnout are extremely likely to occur. Therefore, it is necessary to maintain and repair it. In the past, the maintenance and repair operations of water pumps were all carried out manually. The operator used a hoisting tool to place the water pump on the repair table and assisted the repair work by using the repair table. However, most of the current operation platforms are composed of simple plate-like parts to form a table structure. When adjusting the position height and direction of the water pump motor, hoisting equipment such as a crane needs to be used in cooperation, and the operation process is relatively cumbersome and inconvenient to use. Based on this, this application proposes a lifting operation platform for repairing water pump motors to solve the above problems. Content of the Utility Model

[0003] The purpose of this application is to propose a lifting operation platform for repairing water pump motors in order to solve the above-mentioned related problems.

Fixed blocks are fixedly installed inside both sides of the placement opening. Hydraulic cylinders are installed on the outside of the two fixed blocks, and the two assembly seats are respectively installed at the output ends of the two hydraulic cylinders.

[0031] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0032] See also Figure 1-10 The present application provides a technical solution: a water pump motor maintenance lifting operation platform, including a base 1 and a lifting platform 2, guide frames 3 are installed on both sides of the outside of the lifting platform 2, and bolts can be used to fix the lifting platform 2 and the guide frames 3 to facilitate assembly and disassembly of the two. Both sides of the inside of the two guide frames 3 are installed with reciprocating movable seats 7, and the four corners of the top surface of the base 1 are installed with combination seats 22, and support rods 4 are rotatably installed inside. The support rods 4 are U-shaped as a whole. The outer ends of the four support rods 4 are respectively matched with the outer rotation of the four movable seats 7. The lifting of the lifting platform 2 is realized by the movement of the movable seat 7. The structural strength of the support rods 4 is good, so that the equipment has a load-bearing capacity of not less than 1.5 tons.

[0033] Furthermore, guide frames 23 facing the center are installed at the four corners of the top surface of the lifting platform 2, and reciprocating clamping seats 9 are installed inside the four guide frames 23. The four clamping seats 9 are all in a right-angle structure. The four clamping seats 9 can clamp and fix the water pump motor 6 placed on the lifting platform 2. Mobile clamps 33 are slidably installed on both sides of the outside of the four clamping seats 9. The outer end of the mobile clamp 33 is installed with a pressure plate 35 that can reciprocate up and down. By adjusting the position of the mobile clamp 9 and adjusting the extension distance of the mobile clamp 33, water pump motors 6 of different sizes can be clamped and fixed. By adjusting the position of the pressure plate 35 and pressing it onto the lower seat of the water pump motor 6, the water pump motor 6 can be prevented from shaking up and down.

[0034] A support base 10 is installed directly below the middle position of the base 1. A turntable 17 is rotatably installed on the top surface of the support base 10. For example, a fixed shaft is provided at the center of the top surface of the support base 10, and a bearing is installed at the center of the lower side of the turntable 17. The turntable 17 is connected to the fixed shaft through the bearing, so that the turntable 17 can rotate. Load-bearing rods 16 are rotatably installed on both sides of the top surface of the turntable 17, and their structural strength should not be less than that of the support rod 4 to ensure that the load-bearing capacity of the entire device is sufficient. A placement opening 20 in the shape of a Chinese character 'zhong' is provided in the middle position of the top surface of the base 1. Reciprocating movable assembly seats 19 are installed inside both sides of the placement opening 20. The assembly seats 19 are rotationally matched with the two load-bearing rods 16. By moving the assembly seats 19, the support base 10 can move up and down reciprocally, and the load-bearing rods 16 can be retracted into the placement opening 20, making the structure of the entire device compact. Wheels 5 are installed at the four corners of the bottom surface of the base 1. The wheels 5 can be selected as Fuma wheels. After the support base 10 is retracted, the equipment is supported by the wheels 5, and the equipment can be freely moved.

[0035] By adopting this solution, the water pump motors 6 of different specifications placed on the lifting platform 2 can be clamped and positioned, and the water pump motors 6 can be lifted and rotated according to the actual situation.

[0036] In the embodiment of the present application:

[0037] Refer to Figure 1 、 3 、4, 5 and 8, fixed blocks 21 are installed inside both sides of the placement opening 20. Hydraulic cylinders 11 are installed outside both of the two fixed blocks 21. The two assembly seats 19 are respectively installed at the output ends of the two hydraulic cylinders 11. The hydraulic cylinders 11 output sufficient pressure to ensure that the equipment can be lifted, and the hydraulic cylinders 11 are placed inside the placement opening 20, which can hide the components to avoid position interference between the components. The piston rods of the hydraulic cylinders 11 extend and retract, thereby driving the assembly seats 19 to move. Connection seats 26 are installed on both sides of the top surface of the turntable 17. The two load-bearing rods 16 are respectively rotationally matched with the two connection seats 26, and the cooperation between them is achieved through pin shafts, which is convenient for assembly and disassembly.

[0038] In the embodiment of the present application:

[0039] Refer to Figure 1 、 3 、6 and 9, guide grooves 24 and installation grooves 25 are respectively provided at both ends and the middle position of the two guide frames 3. The guide grooves 24 are in a cross shape. Four moving seats 7 are respectively installed inside the guide grooves 24. First motors 8 are installed on both sides inside the two installation grooves 25, and lead screws 15 are installed at their output ends. The four moving seats 7 are respectively in threaded cooperation with the four lead screws 15. By rotating the lead screws 15, the moving seats 7 can be driven to move reciprocally.

[0040] See Fig. 9 , shafts 29 are installed on both sides of the outer side of the moving seat 7, and a sliding member 12 is rotatably installed on the outer side of the shaft 29. The sliding member 12 is installed in the guide groove 24 to limit the moving seat 7 to prevent it from shaking left and right, and to reduce the friction between the parts, so that the moving seat 7 moves smoothly and reduces the damping. The sliding member 12 can be an "H"-shaped slider or a roller with a groove on the outer circumference, see Figure 6 The sliding member 12 is connected with the guide groove 24 by sliding guide. The two sides of the opening of the support rod 4 are respectively rotatably matched with a set of shaft rods 29, which is convenient for assembling the two and can limit the left and right positions of the movable seat 7.

[0041] In the present application embodiment:

[0042] Reference Figure 2 , 7 and 10, the threaded rods 13 are rotatably installed inside the four guide frames 23, and the bottom surfaces of the four clamping seats 9 are installed with fixed seats 30, which are respectively threadedly matched with the four threaded rods 13. The size of the fixed seat 30 is adapted to the size inside the guide frame 23, which can play a limiting role so that the clamping seat 9 can only move back and forth, and the outer end of the threaded rod 13 is installed with a handle or a handwheel to facilitate the rotation of the threaded rod 13.

[0043] Studs 31 are installed on both sides of the outer surface of the clamp seat 9, and the movable clamp plate 33 is slidably matched with the stud 31, and the external thread of the stud 31 is installed with a locking cap 32, which can fix the position of the movable clamp plate 33, and the outer end thread of the movable clamp plate 33 is installed with a vertically arranged bolt 34, and the pressure plate 35 is rotatably matched with the bolt 34. By tightening the bolt 34, the pressure plate 35 can be raised and lowered, and the water pump motor 6 can be tightened.

[0044] In the present application embodiment:

[0045] Reference Figure 3 , 4 8, the top surface of the support base 10 is surrounded by limit plates 18, which can limit the position of the turntable 17 and prevent the turntable 17 from leaving the support base 10 when the force is unbalanced. A pin is fixed on the lower side of the limit plate 18, and a gear 27 is installed on the pin through a bearing. A second motor 14 is also installed on the upper side of one of the limit plates 18, and the gear 27 is driven to rotate by the second motor 14. A gear ring 28 is installed on the outside of the turntable 17, which meshes with the four gears 27. The turntable 17 can be rotated by the rotation of the gear 27, thereby realizing the rotation of the lifting platform 2.

[0046] Working principle:

[0047] Put the water pump motor 6 on the lifting platform 2, adjust the positions of the four clamping seats 9, and then adjust the positions of the movable clamping plate 33 and the pressing plate 35 to clamp and press the lower seat of the water pump motor 6. After moving the device to a suitable position, the lifting and lowering of the support base 10 is achieved by the extension and retraction of the piston rod of the hydraulic cylinder 11. When the piston rod of the hydraulic cylinder 11 is extended, the support base 10 moves down to support the ground, so that the wheels 5 are suspended and the equipment is propped up. The second motor 14 drives the turntable 17 to rotate to realize the rotation of the lifting platform 2. The four first motors 8 drive the four movable seats 7 to move synchronously, and the lifting platform 2 is raised, which is convenient for adjusting the height and direction of the water pump motor 6.

[0048] After the base 1 and the lifting platform 2 as well as the base 1 and the supporting base 10 are folded together through the above structure, the device has a small volume.

[0049] The above is only a preferred specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed in the present application according to the technical solution and application concept of the present application, which should be covered by the protection scope of the present application.
