Embodiment Construction

[0020] Below by embodiment, in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail:

[0021] Example:

[0022] See figure 1 , figure 2 . In this example, the inclined shaft concrete lining construction transport trolley safety traction system, the length of the inclined shaft 1 sometimes reaches 450 meters. See image 3 , a coaxial double-drum area winch 5 has a main shaft 5-1, the main shaft passes through the reel 5-2, and the middle and two ends of the reel respectively have partitions 5-3, and the reel is divided into two rope areas; The main shaft 5-1 is connected with a motor with a brake through a reducer, and the motor and the brake are electrically connected with the main control cabinet 19. Two traction wire ropes 8-1 and 8-2 are respectively drawn out from the two rope areas for traction and movement; the two traction wire ropes are respectively fixed on the traction rope overload automatic alarm shut...

Abstract

The invention relates to a safe traction system of an inclined-shaft concrete lining construction transportation trolley and overcomes the problem that a safe transportation trolley is low in safety factor. The safety traction system comprises a main control cabinet (19), a concrete lining slip form trolley (2) and a transportation trolley body (11). Two traction wire ropes (8-1 and 8-2) are led out from two barrels of a coaxial double-barrel hoist (5) on the transportation trolley body (11) and respectively fixed above automatic balance oil cylinders (10-1 and 10-2) of the trolley body (11) through a traction rope overload alarm device (7), and a rubber tube (10-3) is communicated between hydraulic oil chambers of the two oil cylinders; the main control cabinet (19) is electrically connected with the traction rope overload alarm device (7), a laser ranging alarm apparatus (15), the coaxial double-barrel hoist (5) and a handheld wireless remote control scram controller (17).

Description

technical field [0001] The invention belongs to the field of traction systems for engineering construction, in particular to a safety traction system for transport trolleys for transporting construction personnel and materials during the construction process of concrete lining of large-inclination and deep-long inclined shafts. Background technique [0002] There are a large number of deep and long inclined shaft constructions with large angles in our country, such as inclined shafts for diversion of pumped storage power stations in hydropower projects, construction inclined shafts for coal mines and metallurgical mines, etc. Inclined shaft excavation or concrete lining construction, the tasks of transporting personnel and materials up and down are generally completed by hoisting the transport trolley on the inclined shaft track. In the construction of the inclined shaft of the pumped storage power station, the angle of the inclined shaft can reach 50°, the total tonnage of ...
