A new type of cargo cableway protection net device and its control method

Abstract

The invention discloses a novel cargo ropeway protective screen device and a control method thereof, the device comprises a motor control system, a protective screen and a winding plant arranged below a ropeway truss, two lower corners of the protective screen are respectively fixed at the bottoms of two support rods at two sides of the ropeway truss, one upper corner is connected with the steel wire rope of the winding plant while the other upper corner is fixed at the upper part of the support rod at the same side through a suspension rope; the device further comprises the photoelectric sensors arranged on the saddle shelves at two sides. The photoelectric sensor sends the feedback signal to the motor control system while detecting a walking car, the motor control system controls the decline of the protective screen, the protective screen is lifted after that the walking car passes through. The novel cargo ropeway protective screen device can have protection function after that the rope clip has the strop ropeway accident, guarantee the safety for the cargo ropeway device and the workers, the device is low in cost, effective, safe and reliable in operation and the device has significant practical meaning.

Description

technical field [0001] The invention relates to the technical field of automatic control for safety protection of freight cableways, in particular to a novel protective net device for freight cableways and a control method thereof. Background technique [0002] Freight cableways often operate in remote mountainous areas with relatively difficult conditions, and it is necessary to do a good job of safety protection for on-site operators and equipment. Due to the slippage and breakage of the bolts on the trolley, the insufficient axial pre-tightening force of the bolts, and the limited service life of the gripper, etc., the gripping force of the gripper is insufficient and the slippery phenomenon occurs, especially when walking. During the process of loading goods on the trolley and going up, the equipment on the construction site may be damaged, making it impossible to continue the operation, or the personal safety of the staff may be injured and other major accidents may occ...

AI Technical Summary

Problems solved by technology

At the job site, the site space is narrow and there is not enough space to allow the installation of large protective devices, and the freight cableway is temporary and has a short period of time. The general period is only 2-3 months, and large equipment is frequently transferred to the site; Due to many factors such as cost, installation and transportation, the workers on the construction site did not install traditional safety protection devices, resulting in some unexpected accidents.
