[0002] Pump station maintenance is an important and complex task, which involves comprehensive inspection, repair and replacement of internal equipment of the pump station to ensure the normal operation of the pump station and extend the service life of the equipment. When performing pump station maintenance, certain specifications and processes must be followed, and appropriate tools and equipment must be used. However, there is a lack of suitable equipment for the maintenance of underground suspended components of the pump station hoist. Traditional lifting tools cannot guarantee the safety of the staff, and cannot solve the problem of the cage shaking in the air, which reduces the work efficiency of the staff.

[0003] Therefore, a safe lifting tool for pump station maintenance is designed to solve the above problems. Utility Model Content

[0004] To solve the problems raised in the above background technology. The utility model provides a safe lifting tool for pump station maintenance. Through the stabilizing ball and the flow-blocking ring, when the copper cage is shaken by external force, the liquid inside the stabilizing ball will be driven to shake. Due to the chamfer of the flow-blocking ring, it is easier for the liquid to enter the flow-blocking ring, and it is more difficult for the liquid to flow out of the flow-blocking ring. When the liquid easily enters the flow-blocking ring, the stabilizing ball can quickly respond to external vibration or wind force, and the stabilizing ball and the internal liquid can immediately generate damping force, start to absorb and disperse vibration energy, and it is more difficult for the liquid to come out of the flow-blocking ring, which means that the liquid will experience greater resistance during the outflow process. This resistance will further consume vibration energy, increase the damping effect of the stabilizing ball, reduce the shaking of the copper cage caused by strong winds, and ensure the construction efficiency and life safety of the staff.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a safe lifting tool for pump station maintenance, comprising a gantry, and also comprising a stabilizing component arranged outside the gantry;

When the liquid easily enters the baffle ring, the stabilizing ball can quickly respond to external vibrations or wind force, and the stabilizing ball and the internal liquid can immediately generate damping force and begin to absorb and disperse vibration energy. It is more difficult for the liquid to come out of the baffle ring, which means that the liquid will experience greater resistance during the outflow process, and this resistance will further consume vibration energy, thereby increasing the damping effect of the stabilizing ball and reducing the shaking of the copper cage caused by strong winds, thereby ensuring the construction efficiency and life safety of the working staff.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1 As shown;

[0022] A safety hoisting tool for pump station maintenance comprises a gantry 1.

[0023] In this implementation scheme: Pump station maintenance is an important and complex task, which involves comprehensive inspection, repair and replacement of internal equipment of the pump station to ensure the normal operation of the pump station and extend the service life of the equipment. When performing pump station maintenance, certain specifications and processes must be followed, and appropriate tools and equipment must be used. However, there is a lack of suitable equipment for the maintenance of underground suspended components of the pump station hoist. Traditional lifting tools cannot guarantee the safety of the staff, and cannot solve the problem of the cage shaking in the air, which reduces the work efficiency of the staff. In order to solve this technical problem, a stabilizing component 2 is added on this basis.

[0024] More specifically:

[0025] like Figures 1 to 4 As shown:

[0026] In combination with the above content: the stabilizing component 2 includes an electric hoist 21, a first rope 22 and a second rope 23. The electric hoist 21 is installed on the outer side of the end of the gantry 1, and the first rope 22 is connected to the outer side of one end of the electric hoist 21. The second rope 23 is fixedly connected to the outer side of the end of the first rope 22, and the copper cage 24 is fixedly connected to the outer side of the end of the second rope 23. The lower surface of the copper cage 24 is fixedly connected to a stabilizing ball 25, which is a hemispherical structure. The interior of the groove of the stabilizing ball 25 is filled with liquid, and the inner side of the end of the stabilizing ball 25 is fixedly connected to a blocking ring 26, which is a ring structure.

[0027] In the present embodiment: during the use of the lifting tool, the gantry 1 can be moved to the upper part that needs to be inspected or maintained, so that the staff can enter the copper cage 24 and start the electric hoist 21. The electric hoist 21 drives the copper cage 24 to descend through the first rope 22 and the second rope 23. After it is in a suitable position, the electric hoist 21 can be stopped. The lower surface of the electric hoist 21 is fixedly connected with a stabilizing ball 25. The stabilizing ball 25 is a hemispherical structure. When the gantry 1 is affected by wind, especially in strong wind weather, the copper cage 24 will shake. Through the stabilizing ball 25 on the lower surface of the copper cage 24 and the liquid inside, when external force acts on the stabilizing ball 25, the liquid in the stabilizing ball 25 will flow. This flow process will generate a damping force, thereby consuming the shaking energy of the copper cage 24, and can absorb part of the vibration energy brought by the wind, thereby reducing the shaking of the copper cage 24. The hemispherical structure of the stabilizing ball 25 can also change the flow pattern of wind and reduce the direct impact of wind on the stabilizing ball 25. The baffle ring 26 is an annular structure with a hollow interior. At the same time, the inner side of the end of the baffle ring 26 is provided with a chamfer. When the copper cage 24 is shaken by external force, the liquid inside the stabilizing ball 25 will be driven to shake. Due to the chamfer of the baffle ring 26, it is easier for the liquid to enter the baffle ring 26, and it is more difficult for the liquid to flow out of the baffle ring 26. When the liquid easily enters the baffle ring 26, the stabilizing ball 25 can quickly respond to external vibrations or wind force. Due to the smoothness of the liquid flow, the stabilizing ball 25 and the liquid inside can immediately generate a damping force and begin to absorb and disperse the vibration energy. It is more difficult for the liquid to come out of the baffle ring 26, which means that the liquid will experience greater resistance during the outflow process. This resistance will further consume the vibration energy and make the damping effect more significant. Due to the difficulty in flowing out, the liquid stays in the baffle ring 26 for a longer time, so that it can continuously absorb and consume more vibration energy. The baffle ring 26 increases the damping effect of the stabilizing ball 25, reduces the shaking of the copper cage 24 caused by strong winds, and ensures the construction efficiency and life safety of the workers.

[0028] Going further:

[0029] In an optional embodiment, a third rope 28 is fixedly connected to the inner side of one end of the electric hoist 21, a fall arrester 27 is installed on the outer side of the end of the third rope 28, a fourth rope 29 is fixedly connected to the outer side of the end of the fall arrester 27, and the outer side of the end of the fourth rope 29 is fixedly connected to the outer side of the end of the first rope 22.

[0030] In this embodiment: a third rope 28 is fixedly connected to the inner side of one end of the electric hoist 21, and the fall arrester 27 is connected to the end of the third rope 28, and is connected to the first rope 22 through the fourth rope 29. The fall arrester 27 uses the difference in the falling speed of the object to perform self-control, and is hung high and used low. When the first rope 22 breaks, the speed at which the fourth rope 29 is pulled out is significantly accelerated, and the locking system of the fall arrester 27 is automatically locked, so that the pulling distance of the fourth rope 29 is limited to a certain range, which does not cause any harm to the person who has fallen. The work is automatically resumed when the load is released, thereby increasing the safety of the device.

[0031] Going further:

[0032] In an optional embodiment, a plurality of telescopic support legs 210 are rotatably connected to the outer side of the end of the gantry 1 .

[0033] In this embodiment: a plurality of telescopic support legs 210 are rotatably connected to the outer side of the end of the gantry 1. When the gantry 1 is moved to a position requiring maintenance, the telescopic support legs 210 are extended outward. At the same time, the extension length of the telescopic support legs 210 is adjusted accordingly according to the number of people inside the copper cage 24, thereby increasing the adhesion of the device to the ground, thereby increasing the stability and safety of the device.

[0034] Going further:

[0035] In an optional embodiment, a plurality of conical blocks 211 are fixedly connected to the outer side of the end of the telescopic support leg 210 .

[0036] In this embodiment: a plurality of conical blocks 211 are fixedly connected to the lower surface of the end of the telescopic support leg 210. When the telescopic support leg 210 is fixed, the conical block 211 can be inserted into the ground, thereby increasing the friction between the telescopic support leg 210 and the ground, making the fixation between the device and the ground more secure, and further increasing the safety of the device.
