Description

Technical Field

[0001] This utility model relates to the field of hoisting device technology, and more specifically, to a hoisting device for power transmission and transformation engineering construction. Background Technology

[0002] During the construction of power transmission and transformation projects, it is often necessary to hoist large equipment and components such as transformers and towers. At present, the commonly used hoisting devices are generally traditional cranes or hoists. Although these hoisting devices can complete basic hoisting tasks, there are still some problems in practical applications. For example, traditional hoisting devices lack effective stabilization measures, which can easily cause the hoisted equipment to sway, affecting not only the safety of hoisting but also potentially damaging the equipment.

[0003] Utility model patent CN222249697U discloses a hoisting device for power transmission and transformation engineering construction. This hoisting device aims to address the technical problems of potential risks in existing technologies, such as equipment and accessories becoming unstable and falling during hoisting. The hoisting device for power transmission and transformation engineering construction includes a base, a stabilizing component, an operating platform, and an electric reel. The hoisting component of this utility model has clamping structures on all four sides and auxiliary stabilizing components, making it adaptable to various models and shapes of power transmission and transformation engineering equipment or accessories. After clamping, it is highly stable, reducing the possibility of swaying. The stabilizing component secures the connection end of the rope to the hoisting component, and as the hoisting component rises, it limits the impact of external wind forces on the hoisting component when the rope is too long, preventing significant swaying of the hoisting component and thus avoiding safety risks such as equipment and accessories becoming unstable and falling.

[0004] While this technical solution offers the advantage of improved hoisting stability, it also has some shortcomings in practical use. Firstly, the length of the movable seat is constant, resulting in a constant distance between the limiting component and the column. When hoisting components of different sizes, the small distance between the limiting component and the column can cause direct collisions between the objects and the column during hoisting. If the initial length of the movable seat is set too long, it may also obstruct the transportation and transfer of equipment. Secondly, the sleeve directly contacts the sling. Due to the certain play between the sleeve and the sling, wear can occur, eventually damaging the sling and shortening its service life. Therefore, we propose a hoisting device for power transmission and transformation engineering construction. Utility Model Content

[0005] The purpose of this utility model is to provide a hoisting device for power transmission and transformation engineering construction, so as to solve the defects mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A hoisting device for power transmission and transformation engineering construction includes a vertical beam, a boom rod set at the top of the vertical beam, and a stranded reel installed on the boom rod. A sling is mounted on the stranded reel. A servo motor is fixedly installed at the top of the vertical beam.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0033] Please see Figures 1-4 This utility model provides a technical solution: a hoisting device for power transmission and transformation engineering construction, including a vertical beam 1, a boom 10 set at the top of the vertical beam 1, and a stranded reel 11 installed on the boom 10. The stranded reel 11 is driven by an external motor and is equipped with a sling 12. A servo motor 14 is fixedly installed at the top of the vertical beam 1. A lead screw 15 is fixedly installed at the end of the output shaft of the servo motor 14 and is arranged vertically downward. A slider 16 that slides along the vertical beam 1 is threadedly connected to the lead screw 15. A groove 13 is provided in the vertical beam 1 along the height direction of the vertical beam 1. The lead screw 15 is located in the groove 13, and the slider 16 is located in the groove 13 and is slidably connected to the groove 13, which makes the slider 16 more stable during the up and down movement.

[0034] like Figures 1-3As shown, the slider 16 is provided with an extension component 3 for limiting the sling 12. The extension component 3 includes a support plate 30 fixedly installed on the front side of the slider 16. A guide sleeve 31 and a cylinder 34 are fixedly installed on the front side of the support plate 30. A sleeve 33 is detachably connected to the end of the telescopic shaft of the cylinder 34. A guide post 32 is fixedly installed on the side of the sleeve 33. The guide post 32 is slidably connected to the guide sleeve 31. The sleeve 33 is fitted on the sling 12. The telescopic shaft of the cylinder 34 drives the sleeve 33 to slide within the guide sleeve 31 through the guide post 32, realizing the horizontal extension and retraction of the sleeve 33. The limiting position of the sling 12 can be adjusted according to the size of the object being lifted, avoiding collision between the object and the vertical beam 1 during the lifting process, and improving the safety and accuracy of the lifting operation.

[0035] like Figure 1 As shown, a fixed pulley 101 is fixedly installed on the boom 10. The sling 12 passes around the fixed pulley 101, which changes the direction of force on the sling 12, making it easier for the winch 11 to raise and lower the sling 12. At the same time, it also helps to stabilize the running trajectory of the sling 12 and ensures that the lifting operation is carried out smoothly.

[0036] like Figure 1 As shown, a base 2 is fixedly installed at the bottom of the vertical beam 1. A load-bearing area 20 is provided on the base 2. During hoisting operations, a heavy block can be placed in the load-bearing area 20 to increase the weight and stability of the base 2, effectively preventing the base 2 from tipping over during hoisting and improving the overall safety of the hoisting device.

[0037] like Figure 4 As shown, the sleeve 33 is equipped with an anti-wear component 4 to reduce friction between the sleeve and the sling 12. The anti-wear component 4 includes two sets of symmetrical hinged supports 40. The two sets of hinged supports 40 are respectively located near the upper and lower openings of the sleeve 33. The multiple hinged supports 40 in each set are arranged in a ring at equal intervals. Rollers 41 are rotatably connected to the hinged supports 40 via a rotating shaft. The sling 12 passes through the multiple rollers 41. The rollers 41 on the upper and lower sets of hinged supports 40 contact the sling 12, converting the sliding friction between the sling 12 and the sleeve 33 into rolling friction. This greatly reduces the wear of the sling 12, which helps to extend the service life of the sling 12 and reduce equipment maintenance costs.

[0038] like Figure 3As shown, a fixed sleeve 36 is detachably connected to the end of the telescopic shaft of cylinder 34. A connecting rod 361 is fixedly installed on the side of the fixed sleeve 36, and an arc-shaped plate 362 is fixedly installed at the end of the connecting rod 361. The arc-shaped plate 362 is detachably installed on the side of the sleeve 33. A protruding post 35 is fixedly installed at the end of the telescopic shaft of cylinder 34. The fixed sleeve 36 is fitted onto the protruding post 35 and is fixedly connected to the protruding post 35 by fastening screws. A reinforcing rod 37 is fixedly installed on the side of the fixed sleeve 36, and a fixed support 371 is fixedly installed at the end of the reinforcing rod 37. The fixed support 371 is fixedly installed on the end rod of the guide post 32 near the sleeve 33, which facilitates the quick assembly and disassembly of cylinder 34 and sleeve 33, and facilitates the installation, maintenance and repair of equipment. At the same time, the reinforcing rod 37 on the side of the fixed sleeve 36 and the fixed support 371 at its end enhance the stability of the connection between the guide post 32 and the sleeve 33, and ensure the reliability of the extension component 3 during operation.

[0039] When using the hoisting device for power transmission and transformation engineering construction of this utility model, the device is first moved to the construction site. According to the hoisting requirements, the servo motor 14 at the top of the vertical beam 1 is started. The servo motor 14 drives the lead screw 15 to rotate, so that the slider 16 slides up and down in the slide groove 13, adjusts the outward extension component 3 to a suitable height and achieves reasonable limiting of the sling 12.

[0040] Next, observe the size of the object to be hoisted, and by controlling the extension and retraction of the telescopic shaft of the cylinder 34, drive the sleeve 33 to slide in the guide sleeve 31 through the guide post 32, and adjust the sleeve 33 to the corresponding limit position to prevent the object from colliding with the vertical beam 1 during hoisting.

[0041] Then, during the raising and lowering of the sling 12, the roller 41 inside the sleeve 33 comes into contact with the sling 12 to reduce friction between them. At the same time, the servo motor 14 continues to work, driving the extension component 3 to move, so that the sleeve 33 can be fitted onto the corresponding part as the sling 12 is raised and lowered.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
