Description

Technical Field

[0001] The utility model relates to the field of lifting equipment, in particular to a hydraulic lifting platform for repairing electromechanical equipment. Background Art

[0002] Hydraulic lifting platform is a highly used equipment for aerial work in various industries. When performing maintenance work on aerial electromechanical equipment, a series of operations such as inspection, disassembly, maintenance and installation of the equipment are required. The lifting platform needs to be frequently lifted and adjusted to meet the maintenance needs. Frequent fine-tuning of the lifting height has large inertia and poor safety. When there are many equipment parts that need to be sent to the ground for maintenance, frequent lifting to the ground to transport the parts will waste maintenance time. After a certain number of parts are accumulated, they will be transported all at once, which will also delay the maintenance progress and waste maintenance time due to accumulation. In addition, the accumulation of parts on the maintenance platform will affect the maintenance and displacement of the maintenance personnel. Accidental situations such as parts slipping and scattering are also prone to occur during the lifting process. There is also a safety risk of maintenance personnel standing unstable due to inertia. At the same time, frequent lifting and lowering will also reduce the service life of the lifting platform. Therefore, a hydraulic lifting platform that does not require frequent lifting and height adjustment when performing electromechanical equipment maintenance work is required. Utility Model Content

The working platform 3 is a double-layer structure comprising an operating table 31 and a maintenance table 32. The operating table 31 is arranged above the maintenance table 32. A first through hole 31-1-1 is arranged on one side of a first bottom plate 31-1 of the operating table 31 to connect the operating table 31 with the maintenance table 32. A ladder 31-4 is arranged on one side of the first through hole 31-1-1 for people to go up and down. A lifting basket assembly 32-1 is arranged below the first through hole 31-1-1 for carrying maintenance items between the operating table 31 and the maintenance table 32. The operating table 31 comprises a first through hole 31-1-1. A bottom plate 31-1, a guardrail 31-2 and an elevated platform 31-3. The elevated platform 31-3 is divided into two groups and can slide along the guardrail 31-2 to change position, so that maintenance personnel can adjust the maintenance position. Maintenance personnel can use the maintenance platform 32 to repair the disassembled parts without transporting the parts to the ground for maintenance, and it does not hinder other maintenance personnel from performing other maintenance operations on the operating table 31, thereby improving labor efficiency and speeding up the maintenance progress. Rectangular frame baffles 32-3 are also arranged around the maintenance platform 32. The baffles 32-3 are arranged on the inner side of the maintenance guardrail 32-4 and fixed on the second bottom plate 32-2 to prevent the maintenance parts from rolling to the ground.

[0028] The lifting basket assembly 32-1 includes a tray 32-1-1, a guide rail 32-1-2 and a second hydraulic cylinder 32-1-3. The guide rail 32-1-2 is two cylindrical guide rollers arranged on the side of the first through hole 31-1-1. One end of the tray 32-1-1 is sleeved on the cylindrical guide rail 32-1-2, and the second hydraulic cylinder 32-1-3 is arranged at the bottom of the other end. The second hydraulic cylinder 32-1-3 is a multi-stage telescopic hydraulic cylinder. The cylinder body is fixed under the maintenance platform 32 by a bracket. The maintenance platform 3 A second through hole 32-2-1 is provided on the second bottom plate 32-2 of 2, and a piston rod of the second hydraulic cylinder 32-1-3 passes through the second through hole 32-2-1 and is fixed to the bottom of the tray 32-1-1. The second hydraulic cylinder 32-1-3 can drive the tray 32-1-1 to slide up and down along the guide rail 32-1-2. The lifting basket assembly 32-1 moves the parts that need to be repaired, which are disassembled during maintenance, from the operating table 31 to the maintenance table 32, thereby improving the safety of transportation and saving labor.

The connecting rod 31-3-2 is mounted in the support frame 31-3-1 and can slide along the support frame 31-3-1. The sliding of the connecting rod 31-3-2 can connect or separate the two support frames 31-3-1. The two support frames 31-3-1 are connected to form a heightened platform 31-3, which can slide along the guardrail 31-2, so as to change the operating position during maintenance. The support frame 31-3-1 can droop naturally at the guardrail 31-2 in the separated state, and will not hinder the passage and operation of the operating platform 31. The heightened platform 31-3 avoids the frequent fine-tuning of the lifting platform to adapt to the height of equipment maintenance, avoids the instability caused by inertia during high-altitude operations, improves operational safety and reduces risks.
