Description

Technical Field

[0001] This application relates to the field of road and bridge construction, specifically to a lifting device. Background Technology

[0002] A bridge is generally a structure erected over rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. To adapt to the modern, rapidly developing transportation industry, the term "bridge" has also been extended to refer to a structure erected to cross mountains, ravines, adverse geological conditions, or to meet other transportation needs, making travel more convenient. A bridge generally consists of a superstructure, substructure, supports, and auxiliary structures. The superstructure, also known as the bridge span structure, is the main structure that crosses obstacles. The substructure includes abutments, piers, and foundations.

[0003] Chinese utility model patent CN215924274U discloses a lifting device for road and bridge construction. It is equipped with a lifting screw and a lifting shaft. The lifting screw is driven by a servo motor, which drives the lifting shaft to move upward, and then drives the lifting bucket to move upward. Compared with the traditional transmission belt lifting method, it significantly reduces the space occupied and avoids lifting errors due to its own extensibility. The device is connected by screw holes and bolts, and the lifting height can be appropriately adjusted according to the construction site conditions, further improving the performance of this utility model.

[0004] The above-mentioned technical solution can only adjust the height in the direction perpendicular to the bridge when inspecting and maintaining the bridge. That is, it can only move along the lifting screw and cannot be adjusted left or right, which reduces its practicality. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a lifting device that solves the problems mentioned in the background section.

[0006] To achieve the above objectives, this application provides the following technical solution: A lifting device includes a base plate, a scissor lift body, and a steering mechanism. Universal wheels are fixedly connected to the four corners of the lower surface of the base plate, and the upper surface of the base plate is fixedly connected to the lower surface of the scissor lift. The output end of the scissor lift is fixedly connected to the lower surface of the lifting plate. The upper surface of the lifting plate is in contact with the outer surface of the steering mechanism. The steering mechanism includes a steering plate, a rack, a control panel, a fixed rod, a moving motor, a storage bin, a steering motor, a turntable, a first groove, balls, gears, and a first sliding groove. The outer surface of the steering motor is fixedly connected to the lower surface of the lifting plate, and the motor's output shaft passes through the upper surface of the lifting plate and is fixedly connected to the lower surface of the turntable. The outer surface of the turntable is rotatably connected to the outer surface of the second groove on the lifting plate, and the outer surface of the first groove on the lower surface of the turntable is in contact with the outer surface of the balls. The upper surface of the turntable is fixedly connected to the lower surface of the steering plate.

[0007] By adopting the above technical solution, the turntable is rotated by the steering motor, which in turn makes the steering plate rotate, making it easier to adjust the rotation direction of the lifting device. In addition, the ball bearings in the turntable can reduce the friction between the outer surface of the turntable and the outer surface of the second groove, thus improving the overall flexibility to a certain extent.

[0008] Preferably, the upper surface of the steering plate is fixedly connected to the lower surface of the rack, and the lower surfaces of the fixing rods on both sides of the rack are fixedly connected to the upper surface of the steering plate. The outer surface of the rack meshes with the outer surface of the gear, and a first sliding groove is provided on the outer surface of the rack. The first sliding groove is slidably connected to the outer surface of the storage bin, and the lower surface of the storage bin is slidably connected to the upper surfaces of the fixing rods on both sides of the rack.

[0009] By adopting the above technical solution, the lower surface of the storage bin is slidably connected to the upper surface of the rack and the fixed rods on both sides of the rack, thereby increasing the force-bearing area of ​​the lower surface of the storage bin and improving the stability of the overall structure to a certain extent.

[0010] Preferably, the upper surface of the gear is fixedly connected to the output shaft of the moving motor, and the moving motor is fixedly connected to the outer surface of the storage bin. The outer surface of the moving motor is wrapped by the inner wall of the control panel, and the lower surface of the control panel is fixedly connected to the upper surface of the storage bin.

[0011] By adopting the above technical solution, the moving motor is started, which drives the gear to rotate inside the rack, thereby causing the storage bin to slide on the upper surface of the rack and the upper surface of the fixed rod, which improves the flexibility of the overall structure to a certain extent.

[0012] Preferably, the upper surface of the steering plate is fixedly connected to the lower surface of the guardrail, and the inner wall of the guardrail wraps around the outer surface of the rack and the fixing rod.

[0013] By adopting the above technical solution, the guardrail prevents the storage bin from separating from the rack and the fixed rod, thereby enhancing the overall safety performance to a certain extent.

[0014] Preferably, a second sliding groove is provided on the lower surface of the steering plate, the inner wall of the second sliding groove is slidably connected to the outer surface of the counterweight, and electric telescopic rods are fixedly connected to both ends of the lower surface of the steering plate, and the output ends of the electric telescopic rods are fixedly connected to the outer surface of the counterweight.

[0015] By adopting the above technical solution, the counterweight blocks can be slid in the second slide groove by the electric telescopic rods on both sides, which can adjust the center of gravity of the steering plate, prevent the utility model from collapsing, and increase safety to a certain extent.

[0016] Preferably, the upper surface of the base plate is threaded with a bolt, and the lower end of the bolt passes through the lower surface of the base plate and is fixedly connected to the upper surface of the fixing plate.

[0017] By adopting the above technical solution, the fixing plate is brought into contact with the ground by rotating the bolts, thereby increasing the contact area between the utility model and the ground and enhancing the stability of the overall structure to a certain extent.

[0018] This application provides a lifting device. It has the following beneficial effects:

[0019] 1. By starting the steering motor, the steering motor drives the disc to rotate, which in turn causes the steering plate to rotate. When the steering plate rotates to the appropriate position, the steering motor is turned off and the moving motor is started. The moving motor drives the gear to rotate in the rack, which in turn causes the storage bin to slide on the upper surface of the rack and the upper surface of the fixed rod. This allows for steering and horizontal adjustment, which improves the overall practicality to a certain extent and solves the problem that the height can only be adjusted in a single vertical direction.

[0020] 2. By activating the electric telescopic rod on the side away from the storage silo, the electric telescopic rod drives the counterweight to slide in the second slide groove, which can adjust the center of gravity of the steering plate, prevent the utility model from collapsing, enhance the stability of the overall structure, and improve the overall safety performance to a certain extent.

[0026] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] Reference Figures 1 to 4This application provides a lifting device, including a base plate 1, a scissor lift body 2, and a steering and moving mechanism 3. The base plate 1 has casters 102 fixedly connected to the four corners of its lower surface, and its upper surface is fixedly connected to the lower surface of the scissor lift. The output end of the scissor lift is fixedly connected to the lower surface of a lifting plate 201. The upper surface of the lifting plate 201 is in contact with the outer surface of the steering and moving mechanism 3. The steering and moving mechanism 3 includes a steering plate 301, a rack 302, a control panel 303, a fixed rod 304, a moving motor 305, a storage bin 306, a steering motor 307, a turntable 308, a first groove 309, ball bearings 310, gears 311, and a first sliding groove 312. The outer surface of the steering motor 307 is fixedly connected to the lifting plate 201. The lower surface of the plate 201, and the output shaft of the motor passes through the upper surface of the lifting plate 201 and is fixedly connected to the lower surface of the turntable 308. The outer surface of the turntable 308 is rotatably connected to the outer surface of the second groove 202 opened on the lifting plate 201. The outer surface of the second groove 202 opened on the lower surface of the turntable 308 is in contact with the outer surface of the ball 310. The diameter of the ball 310 is equal to the width of the second groove 202. The upper surface of the turntable 308 is fixedly connected to the lower surface of the steering plate 301. The steering motor 307 drives the turntable 308 to rotate, thereby causing the steering plate 301 to rotate, which facilitates the adjustment of the rotation direction of the lifting device. The ball 310 in the turntable 308 can reduce the friction between the outer surface of the turntable 308 and the outer surface of the second groove 202.

[0028] Reference Figure 2 and Figure 3 In one aspect of this embodiment, the upper surface of the steering plate 301 is fixedly connected to the lower surface of the rack 302, and the lower surfaces of the fixing rods 304 on both sides of the rack 302 are fixedly connected to the upper surface of the steering plate 301. The outer surface of the rack 302 meshes with the outer surface of the gear 311, and a first sliding groove 312 is formed on the outer surface of the rack 302. The first sliding groove 312 is slidably connected to the outer surface of the storage bin 306, and the lower surface of the storage bin 306 is slidably connected to the upper surfaces of the fixing rods 304 on both sides of the rack 302, thereby improving the lower surface of the storage bin 306 to a certain extent. The force-bearing area is such that the rotation of gear 311 can drive the storage bin 306 to slide on the upper surface of rack 302. The upper surface of gear 311 is fixedly connected to the output shaft of moving motor 305, and moving motor 305 is fixedly connected to the outer surface of storage bin 306. The outer surface of moving motor 305 is wrapped by the inner wall of control panel 303. The lower surface of control panel 303 is fixedly connected to the upper surface of storage bin 306. Multiple sets of buttons are provided on the outer surface of control panel 303 for controlling steering motor 307, moving motor 305, scissor lift body 2 and electric telescopic rod 5.

[0029] Reference Figure 3 and Figure 4In one aspect of this embodiment, the upper surface of the steering plate 301 is fixedly connected to the lower surface of the guardrail 4, and the inner wall of the guardrail 4 wraps the outer surface of the rack 302 and the fixing rod 304. The guardrail 4 prevents the storage bin 306 from separating from the rack 302 and the fixing rod 304. The lower surface of the steering plate 301 is provided with a second sliding groove 501. The inner wall of the second sliding groove 501 is slidably connected to the outer surface of the counterweight 502. Both ends of the lower surface of the steering plate 301 are fixedly connected with electric telescopic rods 5. The output ends of the electric telescopic rods 5 are fixedly connected to the outer surface of the counterweight 502. The electric telescopic rods 5 on both sides drive the counterweight 502 to slide in the second sliding groove 501, which can adjust the center of gravity of the steering plate 301. The upper surface of the base plate 1 is threaded with bolts 103. The lower end of the bolts 103 passes through the lower surface of the base plate 1 and is fixedly connected to the upper surface of the fixing plate 101. By rotating the bolts 103, the fixing plate 101 is brought into contact with the ground, increasing the contact area between the utility model and the ground.

[0030] All electrical devices in this plan are powered by an external power source.

[0031] Working principle: First, the utility model is moved to the desired position using the casters 102. Then, the bolt 103 is rotated to make it fit against the ground. Next, the scissor lift body 2 is activated to raise the lifting plate 201 to a suitable height. Then, the steering motor 307 is activated on the control panel 303. The steering motor 307 drives the disc to rotate, which in turn causes the steering plate 301 to rotate. When the steering plate 301 rotates to the appropriate position, the steering motor 307 is turned off, and the moving motor 305 is activated. The moving motor 305 drives the gear 311 to rotate in the rack 302, which in turn causes the storage bin 306 to slide on the upper surface of the rack 302 and the upper surface of the fixed rod 304. At the same time, the electric telescopic rod 5 on the side away from the storage bin 306 is activated. The electric telescopic rod 5 drives the counterweight 502 to slide in the second slide groove 501, which can adjust the center of gravity of the steering plate 301, preventing the utility model from collapsing. This allows for steering and leveling adjustments, which improves the overall practicality of the structure to a certain extent.
