It can be understood that the above-mentioned scheme can be used in the structure of the electromechanical installation engineering construction safety protection device.

[0024] According to this specific embodiment, the upper surface of the mounting base 101 is provided with the lifting frame 102, and the lifting platform 103 is provided at one end of the lifting frame 102 away from the mounting base 101, and the upper surface of the lifting platform 103 is provided with the guardrail body 104, and sliding plates 115 are provided on both sides of the bottom of the guardrail body 104, and sliding grooves 116 are provided on both sides of the upper surface of the lifting platform 103, and the sliding plates 115 are adapted to the sliding grooves 116, and the two ends of the two sides of the lifting platform 103 are provided with first through holes 117, and the first through holes 117 are connected with the corresponding sliding grooves 116, and the two ends of each of the sliding plates 115 are provided with second through holes 118, and each of the first through holes 118 is provided at both ends of each sliding plate 115.

The lubricating oil reduces the wear of the meshing point between the output gear 112 and the transmission gear 119, thereby improving the service life of the output gear 112 and the transmission gear 119.

[0034] When using the electromechanical installation engineering construction safety protection device of this embodiment, the output gear 112 and the transmission gear 119 are protected by the protective shell 201 to prevent the external environment from affecting the meshing portion of the output gear 112 and the transmission gear 119, and the sealing plug 203 is screwed to inject lubricating oil into the interior of the protective shell 201 through the injection port 202. The lubricating oil reduces the wear of the meshing portion of the output gear 112 and the transmission gear 119, thereby increasing the service life of the output gear 112 and the transmission gear 119.
