Simple maintenance forklift

Abstract

The invention discloses a simple maintenance forklift. The simple maintenance forklift includes a support assembly supported by the ground, a lifting assembly for lifting height and an mounting assembly for placing a to-be-lifted object. The support assembly includes at least two lower forks arranged in parallel and a connecting support rod which connects the ends of the at least two lower forks and has a rectangular cross section. The end of each lower fork is provided with a rectangular groove matching the connecting support rod. Each lower fork is provided with a lower fork adjusting fixingscrew for limiting the position of the connecting support rod. The simple maintenance forklift is improved based on conventional requirements. Through design, the whole forklift can be disassembled,which helps to transport the forklift to a work site. An integrated internal and external lifting mechanism is adopted to facilitate the lifting of the height. A mode of superposing the lifting mechanisms can be adopted to lift up the height. The lifting structure is simplified to the most extent through screw rod drive to reduce the weight to the greatest extent on the premise of ensuring the strength. Upper forks and the lower forks in the device are made of a high-strength aviation aluminum material, which reduces the weight and ensures the strength.

Description

technical field [0001] The invention relates to the technical field of maintenance equipment, in particular to a simple maintenance forklift. Background technique [0002] In the current substation maintenance, when the isolation switch mechanism box is installed, its weight is about 100kg, because the installation needs to be precisely connected with the vertical pull rod of the isolation switch on the upper part, and on the other hand, it needs to pass through the machine of the isolation switch under the side plate of the mechanism box. The base cement rod is welded. After the final installation, the entire mechanism box is suspended from the ground. The suspended distance must meet the specified requirements, so 5 to 6 staff are required to lift and hold it. It takes a long time for installation and welding, which is time-consuming and laborious. During the process, due to shaking or uneven force during the manual lifting process, the installation quality may not meet th...

Problems solved by technology

[0002] In the current substation maintenance, when the isolation switch mechanism box is installed, its weight is about 100kg, because the installation needs to be accurately connected with the vertical pull rod of the isolation switch on the upper part, and on the other hand, it needs to be connected through the mechanism box side plate. The base cement rod is welded. After the final installation, the entire mechanism box is suspended from the ground. The suspended distance must meet the specified requirements, so 5 to 6 staff are required to lift and hold it. It takes a long time for installation and welding, which is time-consuming and laborious. During the process, due to shaking or uneven force during the manual lifting process, the installation quality may not meet the requirements, resulting in multiple reworks. During the inspection and maintenance of the central vacuum circuit breaker, because the central vacuum circuit breaker The weight of the circuit breaker is about 200kg. If a large device such as a crane or a hanger is used to lift it, the device is bulky and inconvenient to carry. On the one hand, it makes the emergency repair work inconvenient. On the other hand, it also has the problem of time-consuming and laborious , to be disassembled from the main body, 4 to 6 people are required to complete the disassembly work of the central circuit breaker by manpower, the labor intensity of the staff is high, and multiple people are required to cooperate
