[0030] Embodiment

[0031] As Figures 1-4As shown, the present embodiment provides a hydraulic lifting device for municipal road work, including a mobile base plate 1 and two operating platforms 3. The bottom surface of the operating platform 3 is made of a hollow steel plate to reduce the weight of the operating platform 3, thereby facilitating the overall movement and ensuring that the rail electric trolley 8 has sufficient power to drive the operating platform 3 and the staff to rotate. Wheels are installed at the bottom of the mobile base plate 1, and the whole can be moved by traction. No more details are given here. Two hydraulic cylinders 2 are installed on the upper surface of the mobile base plate 1. It should be noted that the two hydraulic cylinders 2 need to move synchronously and in the same direction. Two mutually symmetrical linkage grooves 5 and steering rails 7 are also provided on the upper surface of the mobile base plate 1. The linkage groove 5 is arc-shaped, and a matching rail electric trolley 8 is installed at the steering rail 7. The rail electric trolley 8 is fixed to the bottom of the operating platform 3 through a traction rod, and is used to traction the top operating platform 3 for rotation. It should be noted that the steering rail 7 and the linkage groove 5 on the same side are a concentric circle, which ensures that the traction rod and the hydraulic rod 16 move synchronously during rotation, and a matching linkage mechanism 6 is installed inside the linkage groove 5.

[0032] The bottom of the two operating tables 3 is fixed with a support frame 11 for stably supporting the operating tables 3. The telescopic ends of the two hydraulic cylinders 2 are respectively connected to the bearings 13 embedded in the support frame 11. The support frame 11 is provided with two support grooves 12 on the side away from the bearings 13. The two support grooves 12 are connected to the linkage mechanism 6 at the bottom through two hydraulic rods 16. In detail, the support frame 11 includes two brackets, each of which has two diagonal braces fixed at the end angles on the same side as the bottom of the operating table 3. A group of connecting rods 14 are also fixed between the two brackets on the same side, so as to achieve a diagonal support effect at the bottom of the operating table 3.

[0033] The linkage mechanism 6 includes two iron sliders located inside the linkage groove 5 and an iron fixing rod connected between the two iron sliders. The inner bottom wall of the linkage groove 5 is an electromagnet magnetically connected to the iron sliders and the iron fixing rod. Its function is to ensure the stability of the iron sliders and the iron fixing rods by energizing the electromagnets after the angles are adjusted. The tops of the two iron sliders are provided with slots adapted to the hydraulic rod 16, which facilitates the insertion and fixing of the hydraulic rod 16.

[0034] A guardrail 4 is installed on the top of the two operating platforms 3. An integrally formed hinged plate 15 is provided on one side of the two operating platforms 3 close to the hydraulic cylinder 2. The two hinged plates 15 are hinged with a reinforcement plate 10 through a pin shaft. The rotating end of the reinforcement plate 10 is an arc surface. The arc surface design will not cause jamming during rotation. The reinforcement plate 10 is connected to the movable base plate 1 through a middle support rod 9 to ensure support here.

[0035] The hydraulic lifting device for municipal road work described in this embodiment can synchronously lift two operating platforms 3 by synchronously lifting two hydraulic cylinders 2 when one or two people are performing maintenance on the same side of the equipment.

[0036] When two (or more) people are needed to perform synchronous operations on both sides of the equipment to be maintained, first, the operating platform 3 is synchronously raised as above (the equipment to be maintained needs to be placed between the two operating platforms 3), and then the rail electric trolley 8 is controlled to move, synchronously driving the towed operating platform 3 to be located on both sides of the equipment to be maintained.

[0037] It should be noted that the structure described in the utility model can be implemented in a variety of different forms and is not limited to the described embodiments. Any equivalent transformations made by ordinary technicians in this field using the contents of the utility model specification and drawings, or directly or indirectly applied to other related technical fields, such as the loading and unloading of other items, are included in the protection scope of the utility model.
