[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This power construction lifting equipment is specifically designed as follows: By rotating the bidirectional screw, the moving sleeve is driven to move relative to the power equipment, thereby causing the support plate to squeeze and limit the power equipment. Then, by pulling the adjusting plate upward, the operator observes the scale line. Through the reset property of the first telescopic spring, the toothed plate and the slot are engaged and fixed, thereby fixing and limiting the adjusted plate. This achieves the effect of quickly fixing and limiting the power equipment. Furthermore, the extendable adjusting plate can meet the lifting and fixing effects of various types of power equipment. Compared with the limiting method in the prior art, it improves the stability of the power equipment during the lifting process and greatly reduces the phenomenon of shaking or even falling of the power equipment during movement. By using the lever principle, the small gear drives the large gear to rotate, making it easier for the operator to rotate the rotating plate. Through the reset property of the second telescopic spring, the insertion rod and the insertion hole are engaged and fixed, thereby fixing and limiting the adjusted rotating plate and preventing the threaded rod from rotating due to the weight of the power equipment.

[0016] 1. By rotating the bidirectional screw, the moving sleeve is driven to move relative to the equipment, thereby causing the support plate to squeeze and limit the power equipment. Then, by pulling the adjusting plate upward, the operator observes the scale line. When the top of the adjusting plate is slightly lower than the top of the equipment, the operator pulls the sliding rod to move the toothed plate. At this time, the sliding rod squeezes the first telescopic spring. By releasing the sliding rod, the toothed plate and the slot are locked together by the return property of the first telescopic spring. This fixes and limits the adjusted adjusting plate, thus achieving the effect of quickly fixing and limiting the power equipment. Furthermore, the adjustable plate can be extended to meet the lifting and fixing effect of various types of power equipment. Compared with the limiting method in the existing technology, it improves the stability of the power equipment during the lifting process and greatly reduces the phenomenon of shaking or even falling during the movement of the power equipment, bringing safety to the operator. By selecting the rotating plate on the adjusting plate, one side of the rotating plate is made to fit against the top of the power equipment. Then, by tightening the fixing knob, the angle of the rotating plate is fixed, thereby achieving the effect of squeezing and limiting the top of the power equipment, further improving the stability of the power equipment during lifting.

[0017] 2. By operating the rotating disc, the small gear rotates, which in turn rotates the large gear, which in turn rotates the rotating rod, which in turn rotates the first rotating tooth, which in turn rotates the second rotating tooth, which in turn rotates the threaded rod. This threaded rod then moves the moving block and mounting plate up and down. The rotation of the large gear by the small gear utilizes the lever principle, making it easier for workers to rotate the disc. Pulling the moving rod moves the insertion rod, causing the second tension spring to contract. Releasing the moving rod and then using the restoring property of the second tension spring allows the insertion rod to engage and fix with the insertion hole, thus fixing and limiting the adjusted rotating disc and preventing the threaded rod from rotating due to the weight of the electrical equipment.

[0025] 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.

[0026] Please see Figure 1-6 The present invention provides a technical solution: a power construction lifting device, including a vehicle body 1, an installation frame 101 installed on one side of the top of the vehicle body 1, a threaded rod 102 rotatably connected inside the top of the installation frame 101, a moving block 103 threadedly connected to the outside of the threaded rod 102, and a mounting plate 104 fixedly connected to one end of the moving block 103; a limit mechanism 2 is symmetrically arranged at the top of the mounting plate 104, and an adjustment component 3 is arranged inside the installation frame 101;

[0027] The limiting mechanism 2 includes a sliding box 201 fixedly connected to the top of the mounting plate 104. A bidirectional screw 202 is rotatably connected inside the sliding box 201. Moving sleeves 203 are threaded onto the outer sides of both ends of the bidirectional screw 202. A support plate 204 is fixedly connected to the top of the moving sleeve 203. An adjusting plate 205 is slidably connected inside the top of the support plate 204. Slots 206 are provided on one side of the adjusting plate 205, and scale lines 207 are provided on one side of the adjusting plate 205. A fixed box 208 is installed inside one side of the support plate 204. A sliding rod 209 is slidably connected inside the fixed box 208. A toothed plate 210 is fixedly connected to one end of the sliding rod 209. The device is fixedly connected to the slot 206 by a snap-fit ​​mechanism. The two sides of the fixed box 208 are symmetrically provided with sliding grooves 211. The two ends of the toothed plate 210 are symmetrically fixedly connected with sliders 212. A first telescopic spring 213 is installed between the slider 212 and the sliding groove 211. One end of the slider 212 is slidably connected inside the sliding groove 211. This enables the device to be quickly fixed and limited. The adjustable plate 205 can be extended to meet the lifting and fixing requirements of various types of electrical equipment. Compared with the limiting method in the prior art, this improves the stability of the electrical equipment during the lifting process and greatly reduces the phenomenon of shaking or even falling of the electrical equipment during movement, thus bringing safety to the staff when using it.

[0028] A rotating plate 214 is rotatably connected to the top of the adjusting plate 205, and a fixing knob 215 is installed between the rotating plate 214 and the adjusting plate 205. Rubber pads 216 are installed inside one side of both the support plate 204 and the rotating plate 214. By selecting the rotating plate 214 on the adjusting plate 205, one side of the rotating plate 214 is made to fit against the top of the power equipment. The angle of the rotating plate 214 is fixed by tightening the fixing knob 215, thereby achieving the effect of squeezing and limiting the top of the power equipment, further improving the stability of the power equipment during lifting. The design of the rubber pad 216 can effectively avoid rigid contact between the limiting structure and the power equipment, reducing the probability of damage to the power equipment. A multi-stage telescopic rod 217 is symmetrically fixedly connected between the mounting plate 104 and the vehicle body 1, and a third telescopic spring 218 is sleeved on the outside of the multi-stage telescopic rod 217. The design of the multi-stage telescopic rod 217 and the third telescopic spring 218 can assist the up and down movement of the mounting plate 104, making the movement of the power equipment more stable.

[0029] The adjustment assembly 3 includes a mounting box 301 fixedly connected to the bottom of the mounting frame 101. The bottom end of the threaded rod 102 is rotatably connected to the mounting box 301. A rotating rod 302 is rotatably connected to one side of the mounting box 301 and the mounting frame 101. A first rotating tooth 303 is fixedly connected to one end of the rotating rod 302 inside the mounting box 301, and a second rotating tooth 304 is fixedly connected to the bottom end of the threaded rod 102. A second rotating tooth 304 is fixedly connected to the end of the rotating rod 302 away from the mounting box 301. A large gear 305 is attached, and a small gear 306 is rotatably connected to one side of the bottom end of the mounting frame 101. The large gear 305 and the small gear 306 are meshed together, and the small gear 306 drives the rotation of the large gear 305. Utilizing the lever principle, this makes it easier for the operator to rotate the rotating disk 307. The rotating disk 307 is fixedly connected to one side of the small gear 306, and a limit box 308 is fixedly connected to one side of the bottom end of the mounting frame 101. The top of the limit box 308 is slidably connected inside. There is a movable rod 309, and the bottom end of the movable rod 309 is fixedly connected to an insertion rod 310. A second telescopic spring 311 is installed between the movable rod 309 and the limiting box 308. An insertion hole 312 is opened on one side of the rotating disk 307, and one end of the insertion rod 310 is engaged and fixedly connected to the insertion hole 312. By pulling the movable rod 309, the insertion rod 310 is moved. At this time, the second telescopic spring 311 retracts. Then, by releasing the movable rod 309, the second telescopic spring 311 retracts. The resettable nature of the device allows the insertion rod 310 to engage and be fixed with the insertion hole 312, thereby fixing and limiting the adjusted rotating disk 307. This prevents the threaded rod 102 from rotating due to the weight of the electrical equipment, making it more convenient for operators to use. The mounting frame 101 has symmetrical fixed connections to the limiting rod 313, and the moving block 103 is slidably connected to the outside of the limiting rod 313. The design of the limiting rod 313 makes the movement of the moving block 103 more stable.

[0030] Working principle: Before using this type of power construction hoisting equipment, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 6As shown, the worker places the electrical equipment on the mounting plate 104. At this time, the two sets of sliding boxes 201 are located on both sides of the electrical equipment. By rotating the bidirectional screw 202, the moving sleeve 203 moves relative to each other, so that the support plate 204 squeezes and limits the electrical equipment. Then, by pulling the adjusting plate 205 upward, the worker observes the scale line 207. When the top of the adjusting plate 205 is slightly lower than the top of the equipment, the worker pulls the sliding rod 209 to move the toothed plate 210. At this time, the slider 212 squeezes the first telescopic spring 213. Then, by releasing the sliding rod 209, the toothed plate 210 and the slot 206 are locked and fixed by the return property of the first telescopic spring 213. This can fix and limit the adjusted adjusting plate 205, thereby achieving the effect of quickly fixing and limiting the electrical equipment. Furthermore, the adjustable plate 205 can be extended to meet the following requirements. The improved lifting and fixing effect of various types of power equipment, compared with the limiting method in the existing technology, enhances the stability of the power equipment during the lifting process, greatly reducing the phenomenon of shaking or even falling during the movement of the power equipment, and bringing safety to the staff during use. By selecting the rotating plate 214 on the adjusting plate 205, one side of the rotating plate 214 is made to fit against the top of the power equipment, and then the angle of the rotating plate 214 is fixed by tightening the fixing knob 215, thereby achieving the effect of squeezing and limiting the top of the power equipment, further improving the stability of the power equipment during lifting. The design of the rubber pad 216 can effectively avoid rigid contact between the limiting structure and the power equipment, reducing the probability of damage to the power equipment. The design of the multi-stage telescopic rod 217 and the third telescopic spring 218 can assist the up and down movement of the mounting plate 104, making the movement of the power equipment more stable.

[0031] By operating the rotating disk 307, the small gear 306 is driven to rotate. The rotation of the small gear 306 drives the rotation of the large gear 305. The rotation of the large gear 305 drives the rotation of the rotating rod 302. The rotation of the rotating rod 302 drives the rotation of the first rotating tooth 303. The rotation of the first rotating tooth 303 drives the rotation of the second rotating tooth 304. The rotation of the second rotating tooth 304 drives the rotation of the threaded rod 102. Thus, the threaded rod 102 drives the moving block 103 and the mounting plate 104 to move up and down. By using the lever principle, the rotation of the large gear 305 driven by the small gear 306 enables... When the operator rotates the rotating disk 307, it requires less effort. By pulling the moving rod 309, the insertion rod 310 is moved. At this time, the second telescopic spring 311 contracts. Then, by releasing the moving rod 309, the second telescopic spring 311 returns to its original position, which allows the insertion rod 310 to engage and fix with the insertion hole 312. This fixes and limits the adjusted rotating disk 307, preventing the threaded rod 102 from rotating due to the weight of the electrical equipment. This makes it more convenient for the operator to use. The design of the limiting rod 313 makes the movement of the moving block 103 more stable.
