Description

Technical Field

[0001] This utility model relates to the field of water pump hoisting technology, specifically to a water pump hoisting device for water conservancy construction. Background Technology

[0002] The main purpose of water pump hoisting in water conservancy construction is to install water pumps and related components. The water pump is hoisted from the transport location to the pre-prepared installation foundation or pit. For example, in the construction of a pumping station, large water pumps need to be hoisted onto the designed base to ensure accurate positioning and prepare for subsequent commissioning and operation.

[0003] When hoisting water pumps, existing hoists are usually general-purpose, designed to meet various general hoisting needs. They are not specifically designed for the special shape, size, weight, and installation requirements of large pumps in water conservancy projects. Hoists have simple lifting and vertical adjustment functions, but cannot make precise and stable adjustments to the orientation and level of large pumps during hoisting. However, the installation of large pumps in water conservancy projects has extremely high requirements for the orientation and level of the pump. Even a slight deviation can affect the normal operation of the pump. The inability to accurately adjust the orientation and level of the pump will cause deviations from the design requirements, resulting in poor connection between the pump and the inlet and outlet water pipes, increased stress on the pipes, and impede the smooth flow of water, thus reducing the overall operating efficiency of the pumping station. Therefore, we propose a water pump hoisting device for water conservancy construction. Utility Model Content

[0004] The purpose of this utility model is to provide a water pump hoisting device for water conservancy construction to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a water pump hoisting device for water conservancy construction, comprising a circular plate, a cylinder fixedly connected to the surface of the circular plate, a pull ring fixedly connected to the end of the cylinder away from the circular plate, a plurality of grooves formed on the surface of the circular plate, a support arm rotatably connected to the inner wall of the grooves, a winding reel rotatably connected to the end of the support arm away from the circular plate, a rope fixedly wound around the surface of the winding reel, a U-shaped plate fixedly connected to the end of the support arm away from the circular plate, a drive rod threaded through the surface of the U-shaped plate, a limit plate rotatably connected to the end of the drive rod near the winding reel, and a limit groove formed on the arc surface of the winding reel.

[0006] The effect achieved by the above components is as follows: by using four ropes to fix the water pump from four directions, the angle of the water pump after being lifted can be adjusted according to the length of the ropes, so as to ensure that the orientation and level of the pump can be stably adjusted during hoisting to achieve the predetermined angle and position, thereby improving the installation effect of the water pump.

[0007] Preferably, guide grooves are provided on both sides of the U-shaped plate, and guide blocks are fixedly connected to both sides of the limiting plate, with the guide blocks sliding against the inner wall of the guide groove.

[0008] The effect achieved by the above components is that when the limiting plate moves, it will cause the guide block to slide in the guide groove. The guide groove can prevent the guide block from rotating when it moves, thereby preventing the limiting plate from rotating.

[0009] Preferably, hook A is fixedly connected to the surface of the support arm, hook B is fixedly connected to the arc surface of the cylinder, and steel wire rope is sleeved on the surface of hook A and hook B.

[0010] The effect achieved by the above components is that the rotation of the support arm will pull the steel wire rope. When the support arm is fully extended, the steel wire rope will be in a taut state, thereby further improving the support effect of the support arm.

[0011] Preferably, a plurality of fixing plates are fixedly connected to the surface of the circular plate, and pins slide through the surface of the fixing plates. Two circular holes are opened on the surface of the support arm, and the size of the pins is adapted to the size of the circular holes.

[0012] The effect achieved by the above components is that after the pin passes through the round hole, the pin restricts the rotation of the support arm, thereby preventing the support arm from rotating during hoisting.

[0013] Preferably, a threaded rod is threadedly inserted into the surface of the cylinder, the threaded rod passes through the circular plate, and a pressure plate is rotatably connected to the end of the threaded rod away from the cylinder.

[0014] The effect achieved by the above components is as follows: the movement of the threaded rod will drive the pressure plate to move closer to the water pump. When the pressure plate moves to the appropriate position, it will squeeze the water pump, thereby further improving the fixing effect on the water pump and further preventing the water pump from shaking during hoisting.

[0015] Preferably, a turntable is fixedly connected to the surface of the threaded rod, and the cross-section of the turntable is in the shape of a cross.

[0016] The effect achieved by the above components is that the rotation of the turntable will drive the threaded rod to rotate.

[0017] Preferably, the surface of the pressure plate is covered with a protective pad, which is made of rubber.

[0018] The effect achieved by the above components is that the pressure plate will drive the protective pad to squeeze the water pump, and the protective pad will prevent the pressure plate from squeezing the water pump and causing wear to the water pump.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This invention uses four ropes to fix the water pump from four directions, thereby adjusting the angle of the pump after it is lifted according to the length of the ropes. This ensures that the orientation and level of the pump can be stably adjusted during hoisting to achieve the predetermined angle and position, thus improving the installation effect of the water pump.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-2This utility model provides a technical solution: a water pump hoisting device for water conservancy construction, including a circular plate 1, a cylinder 2 fixedly connected to the surface of the circular plate 1, a pull ring 3 fixedly connected to the end of the cylinder 2 away from the circular plate 1, a plurality of grooves 4 opened on the surface of the circular plate 1, a support arm 5 rotatably connected to the inner wall of the grooves 4, a winding reel 6 rotatably connected to the end of the support arm 5 away from the circular plate 1, ropes 7 fixedly wound on the surface of the winding reel 6, a U-shaped plate 9 fixedly connected to the end of the support arm 5 away from the circular plate 1, a drive rod 10 threaded through the surface of the U-shaped plate 9, a limit plate 11 rotatably connected to the end of the drive rod 10 near the winding reel 6, and a limit groove 12 opened on the arc surface of the winding reel 6. By using four ropes 7 to fix the water pump from four directions, the angle of the water pump after hoisting can be adjusted according to the release length of the ropes 7, ensuring that the orientation and level of the pump can be stably adjusted during hoisting to achieve the predetermined angle and position, thereby improving the installation effect of the water pump.

[0029] Reference Figure 2 and Figure 3 and Figure 4 As shown in this embodiment: guide grooves 13 are provided on both sides of the U-shaped plate 9, and guide blocks 14 are fixedly connected to both sides of the limiting plate 11. The guide blocks 14 slide against the inner wall of the guide grooves 13. When the limiting plate 11 moves, it will drive the guide blocks 14 to slide in the guide grooves 13. The guide grooves 13 achieve the function of preventing the guide blocks 14 from rotating when moving, thereby preventing the limiting plate 11 from rotating. A hook A15 is fixedly connected to the surface of the support arm 5, and a hook B16 is fixedly connected to the arc surface of the cylinder 2. The surfaces of hooks A15 and hooks B16 are fitted with... The steel wire rope 17 is pulled when the support arm 5 rotates. When the support arm 5 is fully extended, the steel wire rope 17 will be in a taut state, which further improves the support effect of the support arm 5. Several fixing plates 18 are fixedly connected to the surface of the circular plate 1. Pins 19 slide through the surface of the fixing plates 18. Two circular holes 8 are opened on the surface of the support arm 5. The size of the pins 19 is adapted to the size of the circular holes 8. After the pins 19 pass through the circular holes 8, the pins 19 limit the rotation of the support arm 5, thereby preventing the support arm 5 from rotating during hoisting.

[0030] Reference Figure 5As shown, specifically, a threaded rod 20 is threadedly inserted into the surface of the cylinder 2, and the threaded rod 20 passes through the circular plate 1. A pressure plate 21 is rotatably connected to the end of the threaded rod 20 away from the cylinder 2. The movement of the threaded rod 20 will drive the pressure plate 21 to move closer to the water pump. When the pressure plate 21 moves to the appropriate position, it will squeeze the water pump, thereby further improving the fixing effect of the water pump and further preventing the water pump from shaking during hoisting. A turntable 22 is fixedly connected to the surface of the threaded rod 20. The cross-section of the turntable 22 is "+". The rotation of the turntable 22 will drive the threaded rod 20 to rotate. A protective pad 23 made of rubber is covered on the surface of the pressure plate 21. The pressure plate 21 will drive the protective pad 23 to squeeze the water pump. The protective pad 23 achieves the function of preventing the pressure plate 21 from squeezing the water pump and causing wear on the water pump.

[0031] Working principle: When the water pump needs to be hoisted, first, put the hook of the crane on the pull ring 3, then pull the pin 19. The pin 19 will slide within the fixed plate 18 and gradually disengage from the round hole 8. After the pin 19 disengages from the round hole 8, rotate the support arm 5. The support arm 5 will rotate within the groove 4. The rotation of the support arm 5 will pull the wire rope 17, and the support arm 5 will gradually unfold. When the support arm 5 is fully unfolded, the wire rope 17 will be taut, thereby further improving the support effect of the support arm 5. Press the pin 19. 9. The pin 19 moves and slides within the fixed plate 18, gradually inserting into the round hole 8. Once the pin 19 passes through the round hole 8, it restricts the rotation of the support arm 5, thus preventing the support arm 5 from rotating during hoisting. Then, the drive rod 10 is rotated, and its rotation moves within the U-shaped plate 9 via a thread. The movement of the drive rod 10 causes the limiting plate 11 to move away from the winding reel 6. As the limiting plate 11 moves, it causes the guide block 14 to slide within the guide groove 13. The guide groove 13 prevents the guide block 14 from rotating during movement. The rotation of the limit plate 11 prevents it from rotating. After the limit plate 11 disengages from the limit groove 12, pulling the rope 7 causes it to gradually detach from the take-up reel 6. Once the rope 7 has detached a certain length, it is fixed to the surface of the water pump. Then, rotating the drive rod 10 causes the pressure plate 21 to move closer to the take-up reel 6 via a threaded connection, until the limit plate 11 slides into the limit groove 12. The limit plate 11 then restricts the rotation of the take-up reel 6, thus fixing the water pump. The detachment of the rope 7 is then adjusted. The length is adjusted to facilitate the adjustment of the angle after the water pump is lifted. Then, the turntable 22 is rotated. The rotation of the turntable 22 will drive the threaded rod 20 to rotate. The rotation of the threaded rod 20 will move within the cylinder 2 by means of the thread. The movement of the threaded rod 20 will drive the pressure plate 21 to move closer to the water pump. The pressure plate 21 will drive the protective pad 23 to move closer to the water pump. When the pressure plate 21 moves to the appropriate position, the pressure plate 21 will drive the protective pad 23 to squeeze the water pump, thereby further improving the fixing effect of the water pump and further preventing the water pump from shaking during hoisting.
