Problems solved by technology

[0004] The invention provides a safety protection device for hoisting equipment to solve the problem that most of the existing hoisting equipment uses a control system to control the motor. The operating speed cannot be adjusted, resulting in the overspeed operation of the hoisting device, which in turn causes the motor to overspeed, which may lead to safety accidents

Abstract

The invention relates to the technical field of hoisting equipment, in particular to a safety protection device for hoisting equipment and its application in tree transplanting. A safety protection device for hoisting equipment includes a casing, a transmission mechanism and an adjustment mechanism. The casing is fixedly connected to the boom. The transmission mechanism includes a first rotating shaft, a second rotating shaft, multiple connecting shafts, multiple connecting pieces and multiple friction pieces. The adjustment mechanism includes a hydraulic chamber, a first slider and a first rack. The driving mechanism is configured to drive the friction member to rotate. The invention provides a safety protection device for hoisting equipment to solve the problem that most of the existing hoisting equipment uses a control system to control the motor. The operating speed cannot be adjusted, causing the hoisting device to run at an overspeed, which in turn causes the motor to overspeed, which may lead to safety accidents.

Description

technical field [0001] The invention relates to the technical field of hoisting equipment, in particular to a safety protection device for hoisting equipment and its application in tree transplanting. Background technique [0002] Tree transplanting is one of the compulsory landscaping techniques, which highlights the level of landscape engineers. Tree transplanting was seldom used in the early days of reform and opening up, but it began to be used in various big cities in the 1990s, with Shanghai and other Jiangsu and Zhejiang regions bearing the brunt. At that time, there were many opponents. When the real estate industry was booming, big tree transplants were formed on a large scale driven by the capital of economic interests. The rise of various modern communities has urged high-end communities to transplant big trees into a necessary choice. [0003] Because the trees to be transplanted are relatively large, and in order to ensure the survival rate of transplanting la...
