Description

Technical Field

[0001] This utility model relates to the field of submersible pumps, specifically to a submersible pump coupling device and a hoisting tool for the submersible pump coupling device. Background Technology

[0002] Currently, submersible pumps are widely used in flood control and drainage, farmland irrigation, municipal construction, water conservancy construction, and industrial and mining enterprises. However, due to the limited or restricted space in industrial and mining enterprises, maintenance space is limited, and there are dangerous factors such as the accumulation of toxic and harmful substances in some locations. Maintenance personnel have difficulty entering or the risk factor is high. Most existing submersible pumps use flange connections, which are troublesome to install and have a high risk factor.

[0003] In existing technologies, to address this issue, submersible pumps employ a coupling installation method, where a coupling connecting plate is fixedly connected to the pump outlet, and the coupling connecting plate is coupled to a coupling bend. During installation or disassembly, lifting tools such as wire ropes or chains are used to connect the pump lifting lugs. However, these lifting tools corrode due to prolonged immersion, making the pump prone to falling during lifting. Furthermore, relatively tall gantry cranes or cranes are required during use, resulting in inefficient replacement processes. Utility Model Content

A counterweight is installed at one end of the first rotating shaft through a connecting rod.

[0008] Preferably, the second rotating shaft is located between two vertical plates on the coupling bend, and a second lifting rod is vertically mounted at the center of the second rotating shaft.

Detailed Implementation

[0020] The technical solutions of the present invention will be described in a clear, complete and detailed manner below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] Example 1 like Figure 1-2 As shown, a submersible pump coupling device includes a coupling bend 1, which comprises a vertical section, a bend section, and a horizontal section. The lower end of the vertical section of the coupling bend 1 is a flange 6 connected to the submersible pump, and the other end is a horizontal end with a coupling flange. The coupling flange is coupled to a coupling flange on the outlet pipe. The coupling flange includes a coupling connecting plate 2 and a snap fastener 5 at the upper end of the coupling connecting plate 2, with a groove between the coupling connecting plate 2 and the snap fastener 5.

[0022] The upper end of the coupling connection plate 2 is also provided with a sliding device, which includes a horizontally arranged support plate 3 and slide rail positioning grooves 4 at both ends of the support plate 3. The slide rail positioning grooves 4 can move up and down along the slide rod.

[0023] The submersible pump coupling device also includes a loading and unloading device. The loading and unloading device includes a disassembly lock, an installation release device, and a baffle 8.

[0024] The loading and unloading device includes two vertical plates 7 installed on the coupling bend 1. The plates 7 are installed on the horizontal part of the coupling bend and close to one end of the vertical part. Between the two plates 7, a handle 9, a first rotating shaft 10, and a second rotating shaft 14 are arranged sequentially from top to bottom.

[0025] Two first lifting rods 12 are provided on the first rotating shaft 10. The two first lifting rods 12 are vertically connected to the left and right sides of the first rotating shaft 10 in the same horizontal plane. The two ends of the first rotating shaft 10 pass through the vertical plate 7, and a counterweight block 13 is installed at one end through the connecting rod 11.

[0026] A second lifting rod 15 is vertically mounted at the center of the second rotating shaft 14. An anti-slip block 16 is mounted on the second lifting rod 15 to prevent the lifting tool from slipping during lifting. The anti-slip block 16 can be a protruding structure integrally formed with the second lifting rod 15, such as an inclined rod body, where the angle between the rod body and the second lifting rod 15 in the direction away from the connection end is less than 90°.

[0027] The loading and unloading device also includes a "∩" shaped baffle 8, which is located at a certain distance from the vertical plate 7 and is positioned at one end near the coupling flange.

[0028] The ends of the first lifting rod 12 and the second lifting rod 15 are located inside the space formed by the "∩" shaped baffle 8 and the coupling bend 1. The baffle 8 is used to position the first lifting rod 12 and the second lifting rod 15.

[0029] The first rotating shaft 10, the first lifting rod 12, the connecting rod 11, and the counterweight 13 form a disassembly locking device; the second rotating shaft 14, the second lifting rod 15, and the anti-slip block 16 form an installation release device.

[0030] When installing a water pump using the submersible pump coupling device of this utility model, first connect the connecting flange 6 of the coupling device to the outlet of the submersible pump. Then, place the loop at the end of the wire rope or lifting sling onto the second lifting rod 15 where the release device is installed. The position of the wire rope or lifting sling should not exceed the anti-slip block 16. Next, lift the submersible pump and coupling device with the wire rope or lifting sling, allowing the slide rail positioning groove 4 to slide down along the slide bar on the outlet pipe support until the coupling device and the outlet pipe form a coupling connection. Continue lowering the wire rope or lifting sling, and the second lifting rod 15 rotates to a vertical position under gravity (e.g., ...). Figure 2 (As shown in the image), detach the wire rope or sling from the second lifting rod 15 and retrieve the wire rope or sling.

[0031] The hoisting tools that can be used in this utility model are such as Figure 3 As shown, the device includes two "L"-shaped supports 17, connected by a pressure rod 18 and a crossbar 19. The pressure rod 18 connects the vertical portion of the support 17, and the crossbar 19 connects the horizontal portion of the support 17. The crossbar 19 has lifting slide rail positioning grooves 20 at both ends, which move up and down along the slide rail. Hooks 21 are provided on the support 17 or the crossbar 19 to secure the lifting ropes and control the up and down movement of the lifting tool to complete the lifting operation. This is only one form of lifting tool provided by the present invention. Other lifting tools, as long as their own weight can press down and lock the first lifting rod 12 to complete the lifting, can also be used to disassemble the submersible pump coupling device of this utility model.

[0032] When disassembling the water pump, connect one end of a wire rope or lifting sling to the hook 21 and the other end to a chain hoist or crane. Slide the slide rail positioning groove 4 downwards along the sliding rod on the outlet pipe support. When the pressure rod 18 descends to the first lifting rod 12 of the locking device, use the weight of the lifting tool itself to press down the first lifting rod 12, so that the pressure rod 18 of the lifting tool is fitted onto the first lifting rod 12, completing the installation of the lifting tool. At this time, due to the gravity of the counterweight 13, the first lifting rod 12 returns to its original position and contacts the baffle 8, completing the locking. Then, use the lifting tool to pull upwards, separating the coupling device from the outlet pipe. The slide rail positioning groove 4 slides upwards along the sliding rod on the outlet pipe support, sliding to the top of the sliding rod and disengaging from it. After placing it on the ground, lift the counterweight 13, press down the first lifting rod 12, and remove the lifting tool, thus disassembling the submersible pump, coupling device, and outlet pipe. Finally, disconnect the connecting flange of the submersible pump and coupling device to complete the disassembly of the submersible pump.
