Embodiment Construction

[0009] Implementation of the present invention will be further described below in conjunction with accompanying drawing:

[0010] Such as figure 1 As shown, the gob-type filling hydraulic support mainly consists of a top beam 1, a tail beam 2, a support base 3, a hydraulic support column 4, a four-bar linkage mechanism 5, a baffle plate 6, a telescopic insert plate 7, and a flexible waterproof cloth 8 , board jack 9, baffle jack 10, traction jack 11 and baffle base 12 constitute. The top beam 1 and the tail beam 2 are respectively fixed on the bracket base 3 through four hydraulic support columns 4 symmetrically arranged, and the rear end of the bracket base 3 is connected with a baffle base 12 through a traction jack 11, and the bracket base 3 and the baffle base 12 Can be moved individually. Traction jack 11, baffle plate jack 10, and plate jack 9 are two, symmetrically arranged. When filling and coal mining work in parallel, the support base 3 can be moved while the baff...

Abstract

The invention relates to a dam-type filling hydraulic bracket in a mined-out region. The dam-type filling hydraulic bracket comprise a top beam, a tail beam, a bracket pedestal, a hydraulic support upright post and a four-connecting rod mechanism, wherein the rear end of the bracket pedestal is provided with a baffle plate pedestal; the baffle plate pedestal is provided with a traction jack of which the front end is hinged with the bracket pedestal together; the rear end of the baffle plate pedestal is hinged with a baffle plate in which a telescopic insertion plate is arranged; the back of the front end of the telescopic insertion plate is fixed with an insertion plate jack of which a pedestal is hinged on the baffle plate pedestal; the back of the baffle plate is hinged with a baffle plate jack of which a pedestal is hinged on the baffle plate pedestal; the baffle plate jack can erect the baffle plate; flexible waterproof cloth extending into a soleplate and two lanes of a working face is attached to the inner sides of the baffle plate and the telescopic insertion plate and is paved from top to bottom; the baffle plate jack can control the baffle plate to rotate back and forth and can keep the baffle plate still when the bracket is removed to ensure that a filler has enough time to be solidified and molded; and after a filling body is solidified, the baffle plate is pulled again to realize the parallel operation of mining and filling. The dam-type filling hydraulic bracket has the advantages of simple structure, high working efficiency, and capability of realizing the parallel operation of filling and mining.

Description

technical field [0001] The invention relates to a goaf filling hydraulic support, which is especially suitable for fully mechanized mining working faces of inclined mines. Background technique [0002] At present, the dam-type filling of high-water materials can raise the liquid level, reduce the distance between the empty roof and control the immediate roof caving. It is a filling method with simple process, intuitive effect and compact filling. However, the current embankment filling often uses single columns and baffles to construct water-retaining embankments, which has low work efficiency and high labor intensity, and the interaction between filling and coal mining restricts the promotion of filling methods with high-water materials. In addition, hydraulic support and filling hydraulic support are used for filling. Although the filling effect is very good, operations such as moving the frame must wait for the filling to solidify, and parallel operations of filling and c...
