Problems solved by technology

However, after the roadway boring machine is excavated, it cannot temporarily support the roof in a timely and effective manner, causing the support to lag
The reason is that it relies on manual handling and assembly into the frame; especially after the roadway is widened, the width of the temporary support bracket increases, and the size and weight of the temporary support bracket increase. The strength is high and the installation time is long, and the surrounding rock state after excavation cannot be effectively controlled. After the roof is empty, the cracks will expand. Even if the bolt is installed later, the continued deformation of the roof cannot be guaranteed.

Embodiment Construction

[0023] Such as figure 1 Shown, a kind of roadway temporary support frame with hoisting track of self-contained, comprises adjustable support and is installed in the conveyer 8 below the middle of adjustable support top beam; The supporting leg oil cylinder 6, the top supporting oil cylinder 3, the side beam 4 and the support frame 5 are composed; the crossbeam is composed of the middle beam 2 and the sleeve beams 1 on both sides of the middle beam; the middle beam 2 and the sleeve beam 1 are hinged Connection, the support leg oil cylinder 6 is connected with the support frame 5 using a ball joint ball and socket connection structure, the support frame 5 is hinged with the side beam 4 by a pin shaft, and the side beam 4 is connected with the telescopic inner cylinder of the sleeve beam 1; One end of the jacking cylinder 3 is hingedly connected to the side beam 4, and the other end is hinged to the sleeve beam 1. When the jacking cylinder 3 stretches, the pulling motion of the s...

Abstract

The invention discloses a roadway temporary support bracket with its own lifting track, which is characterized in that it includes an adjustable bracket and a conveyor installed under the middle of the top beam of the adjustable bracket; the adjustable bracket consists of a beam on the top and two sides The supporting leg oil cylinder, the side beam, the top supporting oil cylinder and the supporting frame are composed; the conveyer is composed of a track provided with sleeve rollers or sleeve roller chains and a transport trolley running on the track; the two sides of the transport trolley There is a hook and a push-pull link mechanism that can hook the adjustable bracket; the track is composed of a fixed track and a movable track, and the tracks of the front and rear adjustable brackets can be connected to form a whole track; after the roadway is excavated, The adjustable bracket waiting to be installed is transported to the newly excavated head by the conveyor on the bracket that has been installed in the previous stage, and does not rely on manual transportation and assembly to the head; it not only reduces labor intensity, but also saves installation time.

Description

technical field [0001] The invention relates to tunnel and coal mine roadway support technology. Background technique [0002] In recent years, with the widespread application of roadway boring machines, the speed of tunneling has been continuously improved. However, after the roadway boring machine excavates, it cannot temporarily support the roof in a timely and effective manner, resulting in a delay in support. The reason is that it relies on manual handling and assembly into the frame; especially after the roadway is widened, the width of the temporary support bracket increases, and the size and weight of the temporary support bracket increase. The strength is high and the installation time is long, and the state of the surrounding rock after excavation cannot be effectively controlled. After the roof is empty, the cracks will expand. Even if the bolts are installed later, the continued deformation of the roof cannot be guaranteed. It is an urgent problem to be solved ...
