Description

Technical Field

[0001] This utility model relates to the technical field of multi-stage pump maintenance equipment, specifically a multi-stage pump maintenance bracket. Background Technology

[0002] A multistage pump is a centrifugal pump in which the inlet and outlet sections and the middle section are connected by a tie rod. It can output a large water pressure and obtains centrifugal force by the rotation of the impeller. When the gas density reaches the working range of the mechanical vacuum pump, it is drawn out, thereby gradually obtaining a high vacuum. The multistage pump achieves air intake, compression and exhaust by changing the pump chamber volume, so it is a variable volume centrifugal pump.

[0003] Currently, when overhauling a faulty multistage pump, it is necessary to place the multistage pump on a maintenance bracket to facilitate maintenance from various angles. However, multistage pumps are generally large in size and weight, and placing them on the maintenance bracket requires multiple people or lifting equipment, which is time-consuming and labor-intensive. Therefore, we have proposed a multistage pump maintenance bracket that can easily place the multistage pump on the maintenance bracket. Utility Model Content

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0023] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0024] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a multi-stage pump maintenance bracket.

[0025] Combination Figure 1-3 As shown, the present invention provides a multi-stage pump maintenance bracket, comprising: a movable base 100 and a bracket assembly 200 disposed on the movable base 100.

[0026] The support assembly 200 includes a lifting mechanism disposed on the movable base 100, a placing mechanism disposed on the lifting mechanism, and a fixing mechanism mounted on the placing mechanism. The lifting mechanism includes a mounting base 210 mounted within the movable base 100, a motor 220 fixed to the mounting base 210, a threaded rod 230 connected to the end of the motor 220, a movable base 240 threadedly connected to the threaded rod 230, a hydraulic rod 250 hinged to the movable base 240, and a fixing frame 260 mounted on the movable base 100. The placing mechanism includes a placing plate 310 hinged to the end of the fixing frame 260, a guide frame 320 hinged to the end of the hydraulic rod 250 and connected to the placing plate 310, and a hydraulic... The second hydraulic rod 330 and the second material plate 340, which is connected to the end of the second hydraulic rod 330 and clamped on the guide frame 320, can be moved by the motor 220 via the bracket assembly 200, causing the second material plate 340 to tilt downwards. At the same time, the second hydraulic rod 330 drives the second material plate 340 to move, causing the second material plate 340 to tilt and fall to the ground. In this way, the multi-stage pump to be repaired is tilted onto the second material plate 340, and then dragged at the bottom by the support plate 341 and the fixing rope 342. At this time, the motor 220 drives the moving seat 240 to move. During the process, the first hydraulic rod 250 extends and retracts in coordination, and the second hydraulic rod 330 drives the second material plate 340 to retract until the first material plate 310 and the second material plate 340 support the multi-stage pump to move to a horizontal position. This device does not require multiple people or lifting equipment to operate, and it is relatively time-saving and labor-saving.

[0027] Specifically, a handrail 261 is installed on the fixed frame 260, which facilitates the movement of the support device by the operator, thereby facilitating mobile operation.

[0028] Furthermore, the movable seat 240 has a threaded hole that is threadedly connected to the threaded rod 230, so that the movable seat 240 can be moved when the threaded rod 230 rotates.

[0029] Furthermore, the fixing mechanism includes guide grooves 350 respectively opened on the first material plate 310 and the second material plate 340, guide blocks 360 clamped in the guide grooves 350, positioning plates 370 fixed on the guide blocks 360, positioning grooves 380 opened on the inner side of the positioning plates 370, and pads 390 placed in the positioning grooves 380. The positioning plates 370 can be used to position the pump, and the pads 390 and rollers 391 with rubber structures can be used for padding and support. Not only can pads 390 with different inner cavity shapes be replaced according to the different sizes of the multi-stage pumps, but the multi-stage pumps can also be easily rotated during maintenance, which greatly improves the practicality of the device.

[0030] On the other hand, a sliding roller 391 is installed on the inner side of the pad 390, which facilitates the rotation adjustment of the multi-stage pump on the pad 390, thereby facilitating maintenance at different positions and reducing the workload of manual flipping operations.

[0031] It should be noted that a support plate 341 is inserted into the end of the material placement plate 340, and a fixing rope 342 is connected to the support plate 341. The support plate 341 can support the bottom of the multi-stage pump. Together with the fixing rope 342, it is placed horizontally at the bottom of the multi-stage pump to facilitate the positioning of the multi-stage pump, thereby achieving the lifting effect.

[0032] Furthermore, the second material plate 340 has a slot 343 on its side, and the guide frame 320 has a locking block 344 fixed inside the slot 343, which can make the second material plate 340 stably positioned on the guide frame 320, thus achieving a positioning effect.

[0033] Specifically, the above technical solution also includes a controller for operation. The controller adopts a programmable logic controller (PLC) combined with a dedicated motion control module / card. The core processor is a high-performance industrial-grade microprocessor based on ARM Cortex-A or RISC architecture, located in the main control unit (CPU) of the PLC.

[0034] Control methods include setting working parameters (target position, speed, processing quantity, etc.), selecting programs, and starting / stopping the equipment via HMI (human-machine interface - touch screen);

[0035] The host computer system (such as SCADA, MES) sends control commands and recipe data through the network;

[0036] The signal transmission method is that the motion controller generates a pulse + direction signal (PUL / DIR) or an analog signal (±10V) and sends it to the servo drive via a high-speed industrial bus (such as EtherCAT, PROFINET IRT, CANopen).

[0037] The working principle and usage process of this utility model are as follows: First, the controller controls the motor 220 to drive the moving seat 240 to move, causing the material placement plate 340 to tilt downwards. Simultaneously, the hydraulic rod 330 drives the material placement plate 340 to move, causing it to tilt and fall onto the ground. Figure 2As shown, the multistage pump to be inspected is then tilted onto the second material placement plate 340, and dragged at the bottom by the support plate 341 and the fixing rope 342. At this time, the motor 220 drives the moving seat 240 to move. During the process, the first hydraulic rod 250 extends and retracts, and the second hydraulic rod 330 drives the second material placement plate 340 to retract until the first material placement plate 310 and the second material placement plate 340 support the multistage pump to a horizontal position. Then, the positioning plate 370 is used to position the pump, and the rubber structure pad 390 and the sliding roller 391 are used for padding and support. Not only can the pad 390 with different inner cavity shapes be replaced according to the different sizes of the multistage pump, but it can also make the multistage pump easy to rotate during maintenance.

[0038] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
