Embodiment 1

[0023] Such as figure 1 and 2 As shown, the parallel hydraulic support includes the top beam 6 and the lower front support 9 and the rear support 10. These three parts are the most basic components of the parallel hydraulic support. In this embodiment, the parallel hydraulic support part also includes the joist 7 and the push jack 8; Among them, the front pillar 9, the rear pillar 10 and the top beam 6 are all hinged. Structurally, the overall combined suspension hydraulic support is an unstable structure, and the angle between the support top beam 6 and the front pillar 9 and the rear pillar 10 must pass External forces, such as the friction between the top beam and the top plate are maintained; in this embodiment, the parallel hydraulic support has added a base 1, a rear link 2, a front link 3, a cover beam 4 and a balance bar 5, and the base 1, rear The connecting rod 2, the front connecting rod 3, the cover beam 4 and the balance bar 5 constitute a stable structure for th...

Embodiment 2

[0025] Such as image 3 and 4 As shown, the top beam 6 of the parallel hydraulic support and the lower front support 9 and rear support 10, these three parts are the most basic components of the parallel hydraulic support. In this embodiment, the parallel hydraulic support part also includes the joist 7 and the push jack 8; Among them, the front pillar 9, the rear pillar 10 and the top beam 6 are all hinged. Structurally, the suspension support is an unstable structure, and the angle between the top beam 6 of the parallel hydraulic support and the front pillar 9 and the rear pillar 10 must pass External force, such as the friction between the top beam and the top plate is maintained; in the present embodiment, a base 1, a guide rod group 12 and a gangue board 13 are added, and the guide rod group 12 and the top beam 6 or the gangue board 13 constitute a The stable structure for the sliding support of the present invention; wherein, the base 1 is connected with two rear pillar...

Abstract

The invention discloses a parallel-connection hydraulic support which comprises a top beam, a front supporting mechanism, a rear supporting mechanism, a supporting beam and an advancing jack, and further comprises a stabilization device used for fixing the included angle between the top beam and the rear supporting mechanism. The stabilization device is arranged between the top beam and the base. Potential safety hazards caused by existing instable supports are reduced or eliminated by the support through the supporting mode of fixing a rear column of the support; meanwhile, the destiny that existing instable support products fall into disuse is saved, and severe waste is reduced; meanwhile, the possibility of making the support products such as the combined suspension hydraulic supports continue to serve coal mine users is achieved for the support products.

Description

technical field [0001] The present invention relates to mining equipment. More specifically, it relates to a parallel hydraulic support. Background technique [0002] Coal mine support products are the guarantee for normal mining activities and personnel safety in coal mines. The support products range from wooden supports, metal friction props, single hydraulic props to suspension (slip) hydraulic supports to fully mechanized mining supports, except for fully mechanized mining supports, all of which do not have individual stability. Although the combined suspension hydraulic support product has been widely used in small and medium-sized mines for more than ten years, it has been well received by users for its advantages of small size, light weight, convenient transportation, simple operation, flexible movement, easy maintenance and relative safety. , but the stent product still has instability in the direction of stent movement. Generally speaking, in terms of structure,...
