[0003] Before using a lifting device for power engineering construction, carefully inspect the mechanical parts of the equipment to ensure they are intact, the electrical system is functioning properly, and the safety protection devices are effective. Clear any obstacles around the work area and confirm that the ground's load-bearing capacity meets requirements. During operation, trained personnel must start the device according to the equipment's operating procedures. Slowly adjust the lifting button to smoothly control the height and avoid sudden rises and falls. During operation, constantly monitor the device's load to ensure it does not exceed the rated load; overloading or uneven loading is strictly prohibited.

[0030] 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.

[0031] Reference Figures 1-3The present invention provides an embodiment of a stable lifting device for power engineering construction, comprising a lifting platform 1. The top of the lifting platform 1 is provided with a lubrication mechanism 2 and a switching mechanism 3. The lubrication mechanism 2 includes a fixed housing 211, which serves as the mounting carrier for the lubrication mechanism 2 and the switching mechanism 3. It provides stable installation and movement space for components such as the ring sleeve 215 and the sealing cylinder 220, limits the movement trajectory of the components, and ensures stable transmission and switching actions. The inner wall of the fixed housing 211 is rotatably connected to the ring sleeve 215. The ring sleeve 215 receives the rotational power transmitted by the helical gear 226, meshes with and drives the cross cylinder ring gear 213, and transmits the power to the cross rod 214, opening the transmission chain of the lubrication mechanism 2. The inner wall of the ring sleeve 215 is meshed with the cross cylinder ring gear 213. The cross cylinder ring gear 213 rotates with the ring sleeve 215, driving the cross rod 214 to rotate synchronously.Simultaneously, it can move axially with the movable plate 312 to engage or disengage with the ring sleeve 215. In conjunction with function switching, a cross-shaped rotating rod 214 is slidably connected to the inner wall of the cross-shaped rotating ring gear 213. The cross-shaped rotating rod 214 receives power from the cross-shaped rotating ring gear 213, driving the eccentric wheel 216 and the fixed column 217 to rotate, converting the rotational power into the reciprocating motion of the sealing rod 219. An eccentric wheel 216 is fixedly connected to the outer wall of the cross-shaped rotating rod 214. The eccentric wheel 216 rotates with the cross-shaped rotating rod 214, driving the hinge rod 218 to swing through the fixed column 217, converting its own rotational motion into the hinge rod's motion. The reciprocating thrust of 218 drives the sealing rod 219 to slide. A fixed column 217 is fixedly connected to the side wall of the eccentric wheel 216. The fixed column 217 connects the eccentric wheel 216 and the hinge rod 218, transmitting the rotational power of the eccentric wheel 216. This drives the hinge rod 218 to pull the sealing rod 219 along the inner wall of the sealing cylinder 220. The outer wall of the fixed column 217 is hinged to the sealing rod 219 via the hinge rod 218. The hinge rod 218 converts the swing of the fixed column 217 into the linear reciprocating motion of the sealing rod 219, adapting to the sliding trajectory of the sealing rod 219, ensuring that the sealing rod 219 can stably absorb and discharge oil. The sealing rod 219 slides along the inner wall of the sealing cylinder 220. The inner wall of the sealing cylinder 220 slides back and forth, generating negative pressure during sliding to draw in lubricating oil from the oil reservoir 221. Then, pressure is applied to push the oil into the oil outlet pipe 222. The sealing cylinder 220 is slidably connected to the outer wall of the sealing rod 219. The sealing cylinder 220 provides a sealing sliding space for the sealing rod 219, forming a working chamber for negative pressure oil suction and pressurized oil discharge, ensuring stable delivery of lubricating oil to the oil outlet pipe 222. The top of the fixed outer shell 211 is fixedly connected to the oil reservoir 221, which stores lubricating oil, providing a continuous and sufficient oil source for the lubrication mechanism 2, ensuring uninterrupted lubrication operations. The sealing cylinder 220... An oil drip shell 223 is fixedly connected to the inner wall of the elevator 1 via an oil outlet pipe 222. The oil outlet pipe 222 connects the sealing cylinder 220 and the oil drip shell 223, delivering pressurized lubricating oil and precisely guiding the oil to the oil drip shell 223 to ensure that the lubricating oil is delivered as needed. The oil drip shell 223 receives the lubricating oil delivered by the oil outlet pipe 222 and drips the oil evenly onto the key moving parts of the elevator 1 through the oil drip hole 227 to achieve lubrication. The inner wall of the oil drip shell 223 has oil drip holes 227, which control the dripping speed and the amount of oil dripped at one time to avoid lubricating oil waste and ensure that the oil evenly covers the parts to be lubricated, thereby improving the lubrication effect.

[0032] Reference Figures 1-3The lubrication mechanism 2 also includes a bidirectional motor 224, which is the main power source of the device. One output shaft drives the lubrication mechanism 2 to operate, and the other output shaft drives the lifting precision adjustment mechanism. The outer wall of the bidirectional motor 224 is fixedly connected to the inner wall of the fixed housing 211. A helical gear 225 is fixedly connected to one output shaft of the bidirectional motor 224. The helical gear 225 rotates with the output shaft of the bidirectional motor 224, meshing with and driving the helical gear 226, changing the direction of power transmission, providing rotational power to the ring sleeve 215, and starting the lubrication transmission chain. A helical gear 226 is meshed with the outer wall of gear 225. Helical gear 226 drives the ring sleeve 215 to rotate synchronously, receiving the power of helical gear 225 and transmitting it to the ring sleeve 215, ensuring continuous power transmission of the lubrication mechanism 2. The inner wall of helical gear 226 is fixedly connected to the outer wall of ring sleeve 215. One end of hinge rod 218 is hinged to the inner wall of fixed column 217, and the other end of hinge rod 218 is hinged to the inner wall of sealing rod 219. The outer wall of sealing cylinder 220 is fixedly connected to the inner wall of fixed housing 211. The outer wall of oil outlet pipe 222 is fixedly connected to the inner wall of fixed housing 211. The inner wall of the shell 211 is fixedly connected, the side wall of the oil dripping shell 223 is fixedly connected to the side wall of the fixed shell 211, the bottom end of the fixed shell 211 is fixedly connected to the outer wall of the elevator 1, one end of the oil outlet pipe 222 is fixedly connected to the inner wall of the sealing cylinder 220, and the other end of the oil outlet pipe 222 is fixedly connected to the inner wall of the oil dripping shell 223. The lubrication mechanism 2 also includes a collection box 228, which collects excess lubricating oil collected by the collection tank 229, preventing oil from dripping randomly and polluting the construction environment, and facilitating centralized treatment or recycling of waste oil. The bottom end of the collection box 228 is fixedly connected to the inner wall of the elevator 1. The outer wall of the elevator 1 is fixedly connected, and the inner wall of the elevator 1 is provided with a collection trough 229. The collection trough 229 is located on the inner wall of the elevator 1 to guide the excess lubricating oil flowing along the elevator 1 to the collection box 228, ensuring that no waste oil is leaked and collected, thus improving environmental protection. The lubrication mechanism 2 also includes an oil drain pipe 230, which connects the collection trough 229 to the outside, and discharges the waste oil accumulated in the collection box 228 in a concentrated manner, which facilitates subsequent waste oil treatment and prevents waste oil from accumulating in the collection box 228. The outer wall of the oil drain pipe 230 is fixedly connected to the inner wall of the collection trough 229.

[0033] Reference Figures 2-4The switching mechanism 3 includes an electric actuator 311, which is the power source for the switching mechanism 3. The actuator 311 pushes or pulls the movable plate 312 to slide, thereby adjusting the position of the relevant gears, achieving gear meshing state switching, and control function conversion. The outer wall of the electric actuator 311 is fixedly connected to the inner wall of the fixed housing 211. The movable plate 312 is fixedly connected to the inner rod of the electric actuator 311. The movable plate 312 carries the cross-shaped rotating ring gear 213 and the cross-shaped rotating rod 313, and moves with the electric actuator 311. Adjusting the gear positions allows for engagement or disengagement between the cross-shaped rotary ring gear 213 and the ring sleeve 215, and between the cross-shaped rotary ring gear 214 and the ring sleeve 215. The inner wall of the moving plate 312 is rotatably connected to the outer wall of the cross-shaped rotary ring gear 213. The inner wall of the moving plate 312 is rotatably connected to the cross-shaped rotating rod 213. The cross-shaped rotating rod 213 receives power from the output shaft of the other end of the bidirectional motor 224, driving the cross-shaped rotary ring gear 214 to rotate, thus transmitting power to the lifting accuracy adjustment mechanism. The cross-shaped rotating rod 313 is fixedly connected to the outer wall of the cross-shaped rotating rod 313. The cross-shaped rotating rod 314 rotates with the cross-shaped rotating rod 313, meshing with the ring gear sleeve 315 to transmit power to the threaded rod 212, activating the lifting accuracy adjustment function. The ring gear sleeve 315 is meshed with the outer wall of the cross-shaped rotating rod 314. The ring gear sleeve 315 drives the threaded rod 212 to rotate synchronously, receiving the power from the cross-shaped rotating rod 314 and ensuring that the threaded rod 212 can stably output adjustment power to achieve lifting accuracy control. The threaded rod 212 is fixedly connected to the side wall of the ring gear sleeve 315. The threaded rod 212 adjusts the lifting accuracy or stable state of the lifting machine 1 when rotating through the threaded engagement with the inner wall of the lifting machine 1, adapting to the accuracy requirements of the lifting device in different construction scenarios. The output shaft of the other end of the bidirectional motor 224 is fixedly connected to the side wall of the cross-shaped rotating rod 313, and the outer wall of the threaded rod 212 is fixedly connected to the inner wall of the lifting machine 1.

[0034] Working principle: When the bidirectional motor 224 starts, the output shaft at one end drives the helical gear 225 to rotate. The helical gear 225 meshes with and drives the helical gear 226, causing the ring sleeve 215 to rotate along the inner wall of the fixed housing 211. The ring sleeve 215 meshes with and drives the cross-shaped rotating ring gear 213. The cross-shaped rotating ring gear 213 drives the cross-shaped rotating rod 214 to rotate synchronously. The cross-shaped rotating rod 214 drives the eccentric wheel 216 and the fixed column 217 to rotate. The fixed column 217 pulls the sealing rod 219 along the inner wall of the sealing cylinder 220 through the hinge rod 218. The reciprocating motion of the sealing rod 219 generates negative pressure, which draws the lubricating oil in the oil storage tank 221 into the sealing cylinder 220, and then presses it into the dripping tank 223 through the oil outlet pipe 222. The lubricating oil drips through the dripping hole 227 of the dripping tank 223 onto the key moving parts of the elevator 1, thus achieving lubrication.

[0035] Excess lubricating oil after lubrication flows along the inner wall of the elevator 1 and flows into the collection box 228 through the elevator 1, preventing lubricating oil from dripping and polluting the construction environment. When the waste oil in the collection box 228 accumulates to a certain amount, it can be discharged through the oil drain pipe 230 for subsequent treatment or recycling.

[0036] When the electric actuator 311 is activated, it pushes the moving plate 312 to slide along the inner wall of the fixed housing 211. The moving plate 312 drives the cross-shaped rotating ring gear 213 and the cross-shaped rotating rod 214 to move, causing the cross-shaped rotating ring gear 213 to disengage from the ring sleeve 215. At the same time, it drives the cross-shaped rotating ring gear 314 to engage with the ring sleeve 315. The output shaft of the other end of the bidirectional motor 224 drives the cross-shaped rotating rod 313 to rotate. The cross-shaped rotating rod 313 drives the cross-shaped rotating ring gear 314 to rotate. The cross-shaped rotating ring gear 314 engages and drives the ring sleeve 315, causing the threaded rod 212 to rotate synchronously. The threaded rod 212, through its threaded engagement with the inner wall of the elevator 1, assists in adjusting the lifting accuracy or stability of the elevator 1, adapting to the usage requirements of different construction scenarios.

[0037] When the lubrication function needs to be reactivated, the electric actuator 311 retracts, causing the moving plate 312 to reset, disengaging the cross-shaped rotary ring gear 314 from the ring sleeve 315. The cross-shaped rotary ring gear 213 then re-engages with the ring sleeve 215, and the bidirectional motor 224 switches to drive the lubrication mechanism 2 to operate, restoring the lubrication function.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
