Problems solved by technology

However, when trackless transportation is used in the construction of inclined shafts (such as the transport trolley running along the lined concrete surface), there is still a lack of a safety protection device that can effectively prevent the transport trolley from falling

Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0015] Such as figure 1 and 2 The safety protection device for inclined shaft engineering construction includes connecting rope pulley 1, supporting frame 2, driving spring 3, brake rope pulley block 4, anti-fall device 5, anti-fall device wedge 6, transmission device 7 and brake wire rope 8. The connecting sheave 1 is fixed on the support frame 2, and the transmission device 7 is respectively connected with the driving spring 3 at both ends of the support frame 2 and the wedge 6 of the anti-fall device. 8 passes through the fall arrester 5, and each brake wire rope 8 is clamped by the brake rope pulley block 4 at both ends of the fall arrester 5; the brake rope pulley block 4 is installed on both sides of the safety protection device, and each side has two sets of pulley blocks , the brake wire rope 8 passes through two groups of pulley blocks, so th...

Abstract

The invention discloses a safety protection device for inclined shaft engineering construction, which comprises a connecting sheave, a supporting frame, a driving spring, a brake rope pulley block, a fall arrester, a wedge of the fall arrester, a transmission device and a brake wire rope. The wheel is fixed on the support frame, and the transmission device is respectively connected with the driving springs at both ends of the support frame and the wedge of the fall arrester. It is clamped by the brake rope pulley blocks at both ends of the fall arrester. The invention can ensure that the trackless transport trolley stops the transport trolley by catching the brake wire rope through the fall arrester after losing traction, prevents it from falling along the inclined shaft, and protects the life safety of the construction personnel on the transport trolley and underground.

Description

technical field [0001] The invention belongs to the technical field of engineering construction, and in particular relates to a safety protection device for inclined shaft engineering construction. Background technique [0002] During the construction of the inclined shaft, it is necessary to arrange a lifting transportation system to transport the construction personnel, materials and equipment to the working face in the inclined shaft. The lifting system is mainly composed of lifting equipment, lifting wire rope and transport trolley. The hoisting equipment lifts the trolley up and down in the inclined shaft through the wire rope. If the wire rope of the hoisting trolley breaks or the lifting equipment breaks down, the trolley will fall along the inclined shaft, directly threatening the lives of the personnel carried on the trolley and the construction workers on the underground working face. At present, when rail transportation is used in the construction of inclined sh...
