Description

Technical Field

[0001] The invention relates to the technical field of lifting equipment, and in particular to an electric power equipment lifting device used in electric power engineering construction. Background Art

[0002] Power equipment is the core component of the power system, including generators, transformers, transmission lines, mutual inductors, contactors, etc. These devices are directly involved in the production, conversion, transmission, distribution and consumption of electric energy, and are important carriers to ensure the safe and efficient transmission of electric energy. In the construction of power projects, especially the installation of medium and large power equipment, such as mutual inductors and contactors, due to the heavy weight of the equipment itself, manual support is not only laborious, but also prone to shaking, affecting the installation accuracy and safety. Therefore, professional power equipment lifting devices are needed to assist in the installation.

[0003] Although the existing lifting devices for electric power equipment have made many efforts to pursue stability during the lifting process, their design ideas often fall into an inherent limitation: that is, by continuously increasing the volume of the columns to enhance the bearing capacity and stability of the overall structure. Although this design is reasonable, it has gradually revealed many disadvantages in practical applications: First, as the volume of the columns increases, the floor area of ​​the entire lifting device also increases. However, at the construction site of electric power engineering, especially those sites with limited working space, such as the narrow interior of a substation or the distribution room on a high floor, the existence of large columns has undoubtedly become a "barrier". The increase in the size of the column directly leads to a reduction in the operating range. During the lifting of the power equipment, the construction workers need to ensure that the equipment can reach the designated position smoothly and accurately. However, when the column is too large, the working space around it will be severely restricted, forcing the construction workers to be very careful during the operation, fearing that the slightest negligence will cause the equipment to collide or be damaged. This limitation of the operating range not only reduces the construction efficiency, but also increases the construction risk.

[0004] The patent with application number "CN202321365437.6" discloses: a lifting device for electric power equipment used in electric power engineering construction, including a lifting frame, a lifting mechanism is arranged on the lifting frame, and the lifting mechanism includes a double-headed motor, a rotating rod, a sprocket, a chain, a lifting plate and a load-bearing block, and the front end of the lifting plate is fixedly connected with a left-right moving mechanism, and the left-right moving mechanism is provided with a lifting plate, and the left-right moving mechanism includes a housing, a screw, a moving block and a driving motor. This application improves the stability and safety of electric power equipment during lifting to a certain extent, and avoids the shaking problem during the lifting of equipment. However, due to the influence of its lifting frame and housing, the lifting plate will become unstable when carrying electric power equipment with excessive weight. In addition, the flexibility of the lifting plate is poor, and it is difficult to meet the current construction needs. Summary of the invention

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Example 1

[0030] Please see attached Figure 1-5The present embodiment is a power equipment lifting device for power engineering construction: it includes a base 1, a support beam 2 is fixedly connected to the base 1, a beam frame 3 is hinged on the support beam 2, a slide 4 is slidably connected to one side of the beam frame 3, a lifting frame 5 is installed on the slide 4, a hook 6 is provided at the lower end of the lifting frame 5, and a balancing traction frame is provided on the other side of the beam frame 3.

[0031] The base 1 is used to support the entire device. The base 1 is in contact with the ground. In order to improve the support stability of the base 1, the base 1 can be fixed to the ground by anchor bolts, or adjustable feet can be installed under the base 1 to ensure that after the base 1 is fixed, the support beam 2 at the upper end of the base 1 is in a vertical state. There is a clamping plate at the connection between the support beam 2 and the base 1, and there are bolt holes around the clamping plate. The support beam 2 and the base 1 are buckled together by the cooperation of the fixing bolts and the bolt holes, so that the two can be fixed. This facilitates the assembly and disassembly between the base 1 and the support beam 2. The beam frame 3 is located at the upper end of the support beam 2. The upper end of the support beam 2 is hinged to the beam frame 3. The beam frame 3 has the freedom of rotation relative to the vertically placed support beam 2. When performing lifting operations, the beam frame 3 can be adjusted to a position suitable for the operation, thereby improving the adaptability of the device. The beam frame on the left side of the support beam 2 3 is less than the length of the beam frame 3 on the right side of the supporting beam 2. The slide 4 can move on the beam frame 3. The slide 4 is provided with a walking mechanism and a control system. The walking mechanism in the slide 4 controls the movement of the slide 4 relative to the beam frame 3, which is the same as the principle of the horizontal sliding mechanism on the existing single-arm beam, and can play the role of braking limit. After the slide 4 moves to a certain position of the crossbeam, the slide 4 is stationary at this position of the beam frame 3 under the action of the braking system. A lifting mechanism is provided on the lifting frame 5. The lifting rope in the lifting mechanism is connected with the hook 6. The length of the lifting rope is controlled by the lifting mechanism. The length of the lifting rope determines the falling height or lifting height of the hook 6, thereby controlling the lifting height. The slide 4, the lifting plate and the hook 6 are the same as the moving and lifting mechanisms on the single-arm beam in the prior art, and are all existing technologies that have been disclosed, and will not be introduced in detail here.

[0032] The balanced traction frame includes a traction rod 7 and a traction rope 8, one end of the traction rod 7 is hinged to the beam frame 3, and the other end of the traction rod 7 is hinged to a carrier plate 9, and the carrier plate 9 is fixedly connected to the support beam 2, and a sliding sleeve 10 is installed on the support beam 2 below the carrier plate 9, and the sliding sleeve 10 is fixedly connected to the traction rope 8, a first pulley 11 is rotatably connected to the base 1, and a second pulley 12 is rotatably connected to the beam frame 3, the traction rope 8 passes around the first pulley 11 and the second pulley 12 in an N-shaped structure, and the traction rope 8 is fixedly connected to a reel 13.

[0033] The slide 4 is located on the right side of the beam 3. The lifting frame 5 and the hook 6 under the slide 4 are used to lift the power equipment. The balanced traction frame is located on the left side of the beam 3. The balanced traction frame provides a force to the left side of the beam 3 to prevent the beam 3 from tipping over due to unilateral force on the right side of the beam 3 during the lifting process. In order to improve the traction effect of the balanced traction frame, the balanced traction frame has two traction components. One traction component of the balanced traction frame is a traction rod 7. One end of the traction rod 7 is hinged to the beam 3 on the left side of the beam 3 support beam 2, and the other end of the traction rod 7 is hinged to the beam 3 on the left side of the beam 3 support beam 2. The two ends of the traction rod 7 are connected to the carrier plate 9 of the support beam 2 by means of bolts. In order to make the traction rod 7 meet the rotation adjustment of the beam frame 3, the length of the traction rod 7 can be adjusted; another component of the balanced traction frame is a traction rope 8, one end of the traction rope 8 is connected to the sliding sleeve 10 of the balance beam, and the sliding sleeve 10 is located in the middle of the balance beam. The other end of the traction rope 8 is passed around the first pulley 11 and the second pulley 12 in sequence. The first pulley 11 is a fixed pulley, and the second pulley 12 is a movable pulley. The traction rope 8 passes around the first pulley 11 and the second pulley 12. The pulley 12 is fixedly connected to the reel 13, which is used to control the length of the traction rope 8 and acts as a self-locking device after reeling. The reel 13 is based on the same principle as the existing winding and reeling device. Under the action of the above components, the traction rope 8 finally presents an N-shaped structure. The first pulley 11 is fixed on the base 1. The traction rope 8 between the first pulley 11 and the sliding sleeve 10 has an oblique pulling force to the lower left on the middle part of the support beam 2, thereby improving the compressive strength of the middle part of the support beam 2 and avoiding the lateral tipping of the support beam 2 due to unilateral force. The device 13 has the same height as the first pulley 11, so that the traction rope 8 between the right side of the first pulley 11 and the second pulley 12 and between the second pulley 12 and the winder 13 exerts downward pressure on the second pulley 12. The second pulley 12 is subjected to force on the leftmost side of the beam 3, so that there is a downward force on the left side of the beam 3. The second pulley 12 is a movable pulley, and the force exerted on the two is the sum of the forces exerted by the traction ropes 8 at both ends of the second pulley 12, so that the left side of the beam 3 has a more stable support, thereby ensuring the stability of the beam 3 during the lifting operation.

[0034] The beam frame 3 can be a rectangular parallelepiped structure. In addition, the beam frame 3 can also be composed of a first support rod 301 and a second support rod 302. The first support rod 301 and the second support rod 302 each have three groups. The first support rod 301 and the second support rod 302 have a lighter mass than an integral beam frame 3, which reduces the overall weight of the device and improves the stability of the support beam 2 and the base 1. The length of the first support rod 301 is greater than that of the second support rod 302. The first support rod 301 is placed parallel to the second support rod 1307, and the left end of the first support rod 301 is located at On the left side of the support beam 2, the right end of the first support rod 301 is located directly above the right end of the second support rod 302, and the left end of the second support rod 302 is hinged to the support beam 2. The support beam 2 and the first support rod 301, the second support rod 302 and the slide 4 on the right side of the balance beam form a parallelogram mechanism. The parallelogram structure ensures that the slide 4 can remain in a vertical state after the angle of the beam frame 3 is adjusted. In order to avoid the slide 4 from interfering with the rotation of the first support rod 301 and the second support rod 302, a slide 4 is provided with a first support rod 301 and a second support rod 302. The first support rod 301 and the second support rod 302 are connected to each other by a rectangular groove, the width of which is greater than the spacing between the first support rod 301 and the second support rod 302. At the same time, there are slide grooves on the sides of the first support rod 301 and the second support rod 302. The driving wheel 16 for driving the slide 4 to move is located in the slideway 303. The connecting shaft 17 on the driving wheel 16 is rotatably connected to the support of the slide 4. The two connecting shafts 17 on the front and rear sides of the slide 4 are placed up and down. The four connecting shafts 17 and the four driving wheels 16 prevent the slide 4 from deflecting left and right. The driving wheel 16 and the connecting shaft 17 are connected to the driving system and the brake system in the slide 4. Thereby, the driving wheel 16 can move in the slideway 303 while ensuring the locking position after movement. The traction rod 7 and the second pulley 12 are both located on the first support rod 301 on the left side of the support beam 2. The hinge point between the traction rod 7 and the first support rod 301 is located on the left side of the second pulley 12. The traction rod 7 and the traction rope 8 act on the first support rod 301, so that the first support rod 301 transfers the balancing force to the entire beam frame 3 through the balancing quadrilateral mechanism, thereby ensuring the stability of the beam frame 3 during the lifting process, thereby achieving a stable support effect on the beam frame 3.

[0035] In order to facilitate the adjustment of the beam frame, a hydraulic press is installed in the device. The traction rod 7 is a hydraulic telescopic rod. The hydraulic press achieves precise control of the hydraulic telescopic rod by controlling the flow and pressure of the oil. The length change of the hydraulic telescopic rod drives the adjustment of the angle of the beam frame 3. When the hydraulic telescopic rod is extended, it will push the beam frame 3 to rotate around the hinge point, thereby changing the angle between the beam frame 3 and the supporting beam 2. Conversely, when the hydraulic telescopic rod is shortened, the beam frame 3 will return to its original position or rotate in the opposite direction. The hydraulic telescopic rod has a large carrying capacity and can meet the lifting and moving requirements of heavy power equipment. At the same time, the hydraulic transmission has the advantages of smooth movement, no impact and vibration, etc., which can ensure safety and stability during operation. In addition, the hydraulic press is equipped with a control system, which can achieve precise control of the hydraulic telescopic rod, so that the angle adjustment of the beam frame 3 can be accurately controlled.

[0036] The support beam 2 is a columnar structure, and the sliding sleeve 10 is sleeved on the outer side of the support beam 2. The sliding sleeve 10 can be fixed on the support beam 2 by bolts; in addition, after removing the bolts, a balancing rope 14 can be installed on the upper end of the sliding sleeve 10, and the balancing rope 14 passes through the third pulley 15 and is fixedly connected to the slide 4. The third pulley 15 is located on the left side of the balance beam. At the same time, in order to avoid friction between the balancing rope 14 and the first support rod 301 and the second support rod 302, the third pulley 15 is located between the first support rod 301 and the second support rod 302. The third pulley 15 is a fixed pulley. After the balancing rope 14 passes through the third pulley 15, the balancing rope 14 is located in the gap between the first support rod 301 and the second support rod 302. In this way, the balancing rope 14 is prevented from rubbing against the two. The other end of the balancing rope 14 is fixed on the slide 4. On the one hand, the balancing rope 14 will not affect the horizontal sliding of the slide 4. On the other hand, When the slide 4 moves to the right, the slide 4 drives the balancing rope 14 to move to the right, and at the same time, the balancing rope 14 drives the sliding sleeve 10 to move upward along the support beam 2. The balancing rope 14 and the traction rope 8 are in a taut state. At this time, the balancing rope 14 between the third pulley 15 and the slide 4 has a horizontal traction force to the left on the slide 4, providing a horizontal stability for the device. If the device has a force tilting to the lower right, the balancing rope 14 can play a counteracting effect. The connection between the sliding sleeve 10 and the support beam 2 can ensure that when the slide 4 drives the balancing rope 14 to move left and right, the length of the balancing rope 14 can meet the movement requirements of the slide 4, and when the slide 4 moves farther to the left, the height of the sliding sleeve 10 relative to the support beam 2 is closer, so that the inclined point of the support beam 2 is higher, and the higher the inclined point, the better the balancing effect on the support beam 2, thereby making the device more stable as a whole.

[0037] The winder 13 is installed on the base 1, and the winder 13 is located on the left side of the first pulley 11. The winding roller 1301 rotating in the winder 13 is used to control the length of the traction rope 8. The fixed frame 1302 is used to support the winding roller 1301. At the same time, the fixed frame 1302 is provided with a motor and a reducer for controlling the winding roller 1301. The rotation of the winding roller 1301 is controlled by the machine to reduce the labor intensity of the user. In addition, in order to ensure that the traction rope 8 can be stably retracted and released on the winding roller 1301, a wire hole 1303 is opened on the fixed frame 1302. The wire hole 1303 is limited by the traction rope 8 to prevent the traction rope 8 from detaching from the winding roller 1301 during the winding process. Example 2

[0038] The structure is the same as the above embodiment. Figure 6 and Figure 7 As shown, the specific difference of this embodiment is that an extension beam 18 is rotatably connected to the upper end of the slide 4 , a guide rail 19 is provided on the extension beam 18 , and the guide rail 19 is slidably connected to the lifting frame 5 .

[0039] A rotating structure is installed between the extension beam 18 and the slide 4. The extension beam 18 can rotate on the slide 4. The relative rotation between the slide 4 and the extension beam 18 can increase the flexibility of the entire device. Specifically, a gear is installed on the extension beam 18. The gear is fixedly connected to the extension beam 18. A driving wheel is meshed on the outer side of the gear. The driving wheel is rotatably connected to the slide 4. The gear is driven to rotate by the rotation of the driving wheel. The rotation of the gear drives the extension beam 18 to rotate relative to the slide 4. The rotation between the extension beam 18 and the slide 4 can also be achieved by other methods. The guide rail 19 on the extension beam 18 is The movement of the lifting frame 5 plays a guiding and supporting role. The lifting frame 5 is installed with a sliding mechanism that drives the lifting frame 5 to move along the guide rail 19, thereby realizing the movement of the lifting frame 5 relative to the guide rail 19. The movement of the lifting frame 5 can drive the movement of the hook 6. The extension beam 18 can extend to the left relative to the beam frame 3. The sliding connection between the lifting frame 5 and the guide rail 19 can move the lifting frame 5 and the hook 6 to a position further to the left, thereby increasing the lifting range of the device. In addition, the relative rotation between the slide 4 and the extension beam 18 enables the entire device to flexibly adapt to different working environments and operating requirements. Example 3

[0040] The structure is the same as the above embodiment. Figure 8-10As shown, the specific difference of this embodiment is that: the reel 13 also includes a base 1304, the base 1304 is placed flush with the base 1, the base 1304 is rotatably connected to a fourth pulley 1305, the traction rope 8 passes around the fourth pulley 1305 and is fixedly connected to a traction block 1306, and the traction block 1306 is slidably connected to the base 1304; support rods 1307 are slidably connected to both sides of the traction block 1306, the support rods 1307 are fixedly connected to the base 1304, and a spring 1308 that applies force to the traction block 1306 to the left is sleeved on the support rod 1307; the first pulley 11 and the fourth pulley 1305 are both equipped with pulley frames 20, and the base 1 and the support beam 2 are fixedly connected with reinforcing ribs 21.

[0041] An additional base 1304 is fixed on the left side of the base 1. The base 1304 is fixed to the ground by casting or bolts like the base 1. The traction block 1306 on the base 1304 is fixedly connected to the traction rope 8, and the traction block 1306 has a pulling and traction effect on the traction rope 8. The traction block 1306 can slide horizontally under the guidance and support of the support rod 1307. When the sliding sleeve 10 is fixed relative to the supporting beam 2, the upward rotation of the beam frame 3 will lower the height of the second pulley 12. At this time, in order to keep the traction rope 8 in a taut state, the traction block 1306 moves to the left under the action of the spring 1308, so that the traction rope 8 remains in a taut state to ensure the traction effect of the traction rope 8. The spring 1308 has a leftward elastic force on the traction block 1306, so that the second pulley 12 can still keep the traction effect of the traction rope 8 after moving downward; on the contrary, when the right side of the beam frame 3 moves to When rotating downward, the second pulley 12 on the left side of the beam frame 3 moves upward, and the traction rope 8 pulls the traction block 1306 to move left. At this time, the elastic force of the spring 1308 increases the force acting on the traction rope, thereby achieving a better traction effect on the beam frame 3 and ensuring the stability of the beam frame 3; the fourth pulley 1305 is a fixed pulley. The function of the fourth pulley 1305 is to smoothly change the traction direction of the traction rope 8, reduce the friction loss of traction force, and at the same time ensure the service life of the traction rope 8. The first pulley 11 and the fourth pulley 1305 are both supported by the pulley frame 20. Under the action of the pulley frame 20, the traction rope 8 bypassed under the fourth pulley 1305 and the connecting part of the traction block 1306 are placed in a water sheet, thereby ensuring that the force direction of the traction block 1306 is aligned with the direction of the support rod 1307, so that the traction block 1306 can be smoothly translated on the support rod 1307 to maintain the traction state of the traction rope 8.

[0042] In addition, when the sleeve 10 moves relative to the support beam 2, the sliding connection between the traction block 1306 and the support rod 1307 will not affect the vertical sliding of the sleeve 10, but can cooperate with the sleeve 10 to prevent the traction rope 8 from breaking due to excessive force; further, a pad can be installed on the support rod 1307 on the rear side of the spring 1308, and the spring 1308 is located between the pad and the traction block 1306. The position of the pad on the support rod 1307 is adjustable. By adjusting the position of the pad, the force of the spring 1308 on the traction block 1306 is changed, thereby ensuring that the traction block 1306 and the traction rope 8 provide a sufficiently stable traction effect on the beam frame 3.

[0043] The connecting parts of the base 1 and the support beam 2 are provided with reinforcing ribs 21. The reinforcing ribs 21 on the base 1 and the reinforcing ribs 21 on the support beam 2 are symmetrical. The reinforcing ribs 21 reinforce the base 1 and the support beam 2, and improve the compressive strength of the support beam 2 and the base 1. There are multiple reinforcing ribs 21 on the base 1 and the support beam 2. The reinforcing ribs 21 surround the base 1 and the support beam 2 respectively, and the spacing angles between the multiple reinforcing ribs 21 are the same.

[0044] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
