specific Embodiment approach

[0019] The preferred specific embodiment of the personalized roadway support equipment folding protective net device of the present invention is:

[0020] Including 2 first-level hanging nets, and 1 second-level hanging net between the 2 first-level hanging nets;

[0021] In the folded state, the two first-level hanging nets are connected by pin shafts and D-shaped pins, and the second-level hanging nets are overlapped at the joints between the two first-level hanging nets;

[0022] In the open state, the two first-level hanging nets are separated, and the second-level hanging net is assembled at the opening between the two first-level hanging nets, and its two sides are respectively connected with the two first-level hanging nets. Pin shaft and D-pin connection.

[0023] In the folded state, the two primary hanging nets are locked and fixed with bolts and nuts.

[0024] Both the first-level hanging net and the second-level hanging net are composed of equilateral angle steel...

specific Embodiment

[0033] The personalized roadway sliding support is composed of six parallel beams. There is a gap of 350mm between each of the parallel beams. The gap is large, which cannot ensure the safety of underground personnel and prevent the roof from breaking rocks or coal seams from collapsing and hurting people. Now the upper part of the control valve Install the folding protective net device to ensure the safety of underground operators.

[0034] The sliding bracket bears the load of the roof through the joist and the top beam, and the roof is under a huge pressure. In order to ensure the safe operation of personnel in the mine and to adapt to the interchangeability of the left and right working faces, the folding protective net device of the sliding bracket plays a role in protecting the safety of underground workers. played a very important role.

[0035] When the control valve of this set of sliding roadway advance support device is installed on the left side of the forward dire...

Abstract

The invention discloses a folding protective net device of personalized roadway supporting equipment. The folding protective net device comprises two first-stage hanging nets. A second-stage hanging net is arranged between the two first-stage hanging nets. In a folded state, the two first-stage hanging nets are connected with each other through pin shafts and D-type pins and locked and fixed through bolts and nuts, and the second-stage hanging net is overlapped at the joint of the two first-stage hanging nets. In an unfolded state, the two first-stage hanging nets are separated, the second-stage hanging net is spliced at an opening between the two first-stage hanging nets, and the two sides of the second-stage hanging net are connected with the two first-stage hanging nets through pin shafts and D-type pin correspondingly. Lug plates of a folding protective net are hung between a front top beam and a rear top beam of a sliding support through ring chains and shackles. The folding protective net device is applied to a fore support of a crossheading and air return roadway of a fully mechanized coal face, and has the advantages of being high in strength, high in movement speed, good in supporting performance, safe, reliable and the like.

Description

technical field [0001] The invention relates to roadway support equipment, in particular to a personalized roadway support equipment folding protective net device, which is a fully mechanized mining working face along the groove and the return air roadway leading support. Background technique [0002] Sliding roadway advance support is a personalized roadway support equipment, which plays an important role in protecting the support operator. [0003] In the prior art, such as: ZH5600 / 26 / 38D type sliding roadway advance support device is composed of emulsion as the medium, six parallel beams, four cross beams, suspension support mechanism, and push mechanism. Along the direction of the roadway, the shun beam directly contacts with the roof to support the roof, and the shun beam is a two-section hinged structure at the front and back. The upper part of the beam is hinged with the beam, and the lower part is hinged with the suspension support mechanism. The column lifts its le...
