Description

Technical Field

[0001] This utility model relates to the field of emergency rescue technology, specifically to a water pump lifting clamp. Background Technology

[0002] In emergency drainage and disaster relief operations, it is often necessary to connect high-flow-rate drainage pumps with hoses and lower them into deep foundation pits or bodies of water. The traditional method is to directly connect the lifting rope to the pump body. However, even after the pump stops, the water in the hose above the water surface will flow back into the foundation pit, but a large amount of water will still remain in the hose below the pump impeller chamber. This leads to a prominent problem: during lifting, the pump needs to be lifted along with its own weight and the huge weight of the water remaining in the hose, resulting in an extremely large total load. This not only requires the lifting equipment to have greater power and counterweight, but also often requires additional personnel to laboriously drag the hose to assist in the operation. Furthermore, if an attempt is made to directly lift the upper end of the water hose using mechanized equipment, the water pump would need to be raised to a height far exceeding the depth of the pit, which is often difficult to achieve on-site. Throughout the entire emergency rescue site, large lifting equipment usually faces the problems of inconvenient deployment and limited working space. Meanwhile, a small lifting device often needs to take into account the cyclic lifting of multiple water pumps, and its hook cannot and should not be fixed to a single water pump.

[0003] Therefore, since it does not meet the existing requirements, we have proposed a water pump lifting clamp. Utility Model Content

[0004] Therefore, this utility model provides a water pump lifting clamp to solve the above-mentioned problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: According to a first aspect of this utility model, a water pump lifting clamp includes an upper clamping plate with openings on both sides and the bottom, forming a U-shaped structure, and a hollow mounting plate fixedly installed on the top, with the interior of the mounting plate communicating with the inner cavity of the upper clamping plate; a lower clamping plate with detachable blocks on both sides; a magnetic suction plate disposed above the lower clamping plate; an electromagnet installed in the mounting plate for generating magnetic force to attract the magnetic suction plate; a guide mechanism installed between the magnetic suction plate and the upper clamping plate for providing vertical guidance when the magnetic suction plate is attracted; and a lifting ring disposed on the top of the mounting plate; wherein the upper clamping plate, the lower clamping plate, and the side blocks together form a channel for accommodating a water hose, and when the electromagnet is energized, it drives the lower clamping plate to move upward by attracting the magnetic suction plate, thereby clamping the water hose located therein.

[0006] Furthermore, the guiding mechanism includes a guide post fixed to the top of the magnetic suction plate and a guide sleeve fixed to the top of the upper clamping plate, the guide sleeve having a guide hole through which the guide post slides.

[0007] Furthermore, a limiting plate is provided at the top of the guide post, and the cross-sectional area of ​​the limiting plate is larger than the cross-sectional area of ​​the guide hole.

[0008] Furthermore, the bottom sides of the magnetic suction plate are fixedly connected to the top of the stop block by bolts.

[0009] Furthermore, the lower clamping plate, the stop block on one side, and the magnetic suction plate together form a U-shaped opening for laterally inserting a flat water hose after the stop block on the other side is removed.

[0010] Furthermore, the mounting plate and the upper clamping plate are fixedly connected as an integral structure, and the interior of the mounting plate communicates with the interior cavity of the upper clamping plate.

[0011] Furthermore, the inner wall of the guide hole and the outer wall of the guide post form a sliding fit to constrain the lower clamping plate to move vertically during the upward process.

[0012] Furthermore, the channel formed by the upper clamping plate, the lower clamping plate, and the side blocks is a rectangular channel, the size of which is set to allow the flat water hose to slide within it to a limited extent.

[0013] Furthermore, mounting grooves are provided on both sides of the lower clamping plate, and the stop block is detachably installed in the mounting groove by bolts.

[0014] Furthermore, the electromagnet is installed inside the mounting plate, with its bottom extending downwards to the upper part of the inner cavity of the upper clamping plate.

[0015] This utility model has the following advantages: This water pump lifting clamp clamps clamps flat water hoses after they have been emptied of water and uses electromagnetic adsorption to achieve rapid clamping, fundamentally avoiding the additional load caused by the large amount of water in the hose when directly lifting the water pump. This minimizes the counterweight requirements of the lifting equipment, significantly reduces the labor intensity of emergency rescue, and greatly improves the flexibility and response speed of rescue operations. This water pump lifting clamp, through its frame structure consisting of an upper clamping plate, a lower clamping plate, and detachable blocks, forms a rectangular channel that allows the water hose to slide when the electromagnet is not activated. This design allows the device to adapt to the flattened physical characteristics of the water hose after it has been emptied, enabling rapid insertion and precise lowering positioning. This structure cleverly transforms the clamping target from a cylindrical water hose filled with water to a flat, hollow water hose, fundamentally creating the prerequisites for subsequent lightweight lifting. This water pump lifting clamp uses an electromagnet to drive a magnetic suction plate, and through a power transmission mechanism that links the lower clamping plate with a stop block, it achieves precise clamping via remote electrical control. This power system efficiently converts electromagnetic energy into vertical mechanical clamping force, which is responsive and uniform, ensuring reliable locking of the water hose even in complex environments. Combined with the sliding pair formed by the guide column and guide sleeve, the entire clamping process is free from jamming and deflection, significantly improving the stability and safety of the clamping. This makes it possible to use small, lightweight lifting equipment to perform heavy water pump recovery tasks, greatly reducing reliance on large lifting equipment. Attached Figure Description

[0019] Reference Figure 1 - Figure 5A water pump lifting clamp includes an upper clamping plate 1 and a lower clamping plate 2. The upper clamping plate 1 is designed with open structures on both sides and the bottom, and is generally U-shaped. A mounting plate 101 is installed on the top of the upper clamping plate 1, and the interior of the mounting plate 101 communicates with the inner cavity of the upper clamping plate 1. An electromagnet 3 is installed in the mounting plate 101, and the bottom of the electromagnet 3 extends downward into the upper cavity of the upper clamping plate 1. The lower clamping plate 2 has mounting grooves 201 on both sides, and a stop block 8 is detachably installed on the inner wall of the mounting groove 201 by bolts. A magnetic suction plate 5 is provided on the top of the lower clamping plate 2, and the bottom sides of the magnetic suction plate 5 are fixedly connected to the top of the stop block 8 by bolts. Guide posts 4 are fixedly connected to both sides of the top of the magnetic suction plate 5, and guide sleeves 6 are fixedly provided on both sides of the top of the upper clamping plate 1. A through guide hole is opened on the inner wall of the guide sleeve 6. The bottom of the guide hole communicates with the inside of the upper clamping plate 1. The inner wall of the guide hole is slidably connected to the outer wall of the guide post 4. A limiting plate 401 is installed through the guide hole on the top of the guide post 4 to prevent the guide post 4 from detaching from the guide sleeve 6 and to ensure that the lifting process is stable and reliable. A lifting ring 7 is provided on the top of the mounting plate 101 for easy connection with lifting equipment. Working principle: After the water pump stops, the water in the hose above the water surface will flow backward, leaving only water in the part below the water surface. The hose will then flatten out, as... Figure 5 As shown, at this time, the stop block 8 on one side of the lower clamping plate 2 can be removed, so that a "U"-shaped opening is formed between the lower clamping plate 2, the stop block 8 on the other side, and the magnetic suction plate 5; the flattened water hose is then inserted through this opening from the side where the stop block 8 has been removed, as shown. Figure 3 As shown; Then, reinstall the previously disassembled stop 8 so that the lower clamp 2, the upper clamp 1, and the two side stop 8 together form a rectangular channel in which the water hose can slide within a limited range; next, use ropes to lower the entire device down along the water hose until it is close to the water pump. Activate electromagnet 3 to attract magnetic plate 5; under magnetic force, magnetic plate 5 moves stop block 8 and lower clamping plate 2 upwards, thereby reducing the distance between the top surface of lower clamping plate 2 and the bottom surface of upper clamping plate 1, thus clamping and fixing the water hose. At this point, a small lifting device can be used to lift the water pump, water hose, and lifting clamp together to the ground. During this process, when the lower clamping plate 2 moves upward, it will drive the guide post 4 to slide along the guide hole in the guide sleeve 6, which plays a guiding role and ensures the smoothness and accuracy of the clamping action; the limiting plate 401 at the top of the guide post 4 effectively prevents the guide post 4 from coming out, further enhancing the reliability and safety of the overall structure. The application of this device effectively avoids the extra load caused by the direct hoisting of water pumps in traditional methods, which would result in a large amount of water stored in the hose being lifted as well. This minimizes the counterweight of the lifting equipment, reduces the labor intensity of emergency drainage operations, and significantly improves the flexibility of emergency response and operation.
