Embodiment Construction
[0020] Such as Figure 1-Figure 13 As shown, the thin-shell type hydraulic support of the present invention includes a base, a cover beam, a top beam, a front link 1 and a rear link 2 hinged between the base and the cover beam, and a front link 2 arranged between the base and the top beam column. The hydraulic column 3 between the nests; the top of the cover beam is hinged with the rear end of the top beam; Five layers of arc-shaped plates 7,8 are formed on the respective two sides of the two vertical plates 5,6, and upper opening column sockets 9,10 are respectively fixed on the two vertical plates 5,6. The rear ends of the vertical plates 5 and 6 are respectively provided with hinged holes 11 and 12 for hinged connection with the cover beam through the front connecting rod 1 and the rear connecting rod 2; The two side vertical plates 14,15 on the vertical plate 13 are composed of five layers of arc-shaped plates 16,17 respectively fixed on the respective two side plate surf...

The invention discloses a thin-shell hydraulic support. The hydraulic support comprises a base, a shield beam, a top beam, a front connecting rod and a rear connecting rod which are hinged between the base and the shield beam, and a hydraulic vertical post arranged between the base and the top beam, wherein the top of the shield beam is hinged with the rear end of the top beam; the base consists of a bottom plate, two vertical plates fixed on the upper surface of the bottom plate at intervals along the longitudinal direction, and multi-layer arc plates fixed on the two sides of the two vertical plates along the longitudinal direction; the shield beam consists of a vertical plate, two side vertical plates fixed on the vertical plate at intervals along the longitudinal direction, and multi-layer arc plates fixed on the two sides of the two side vertical plates along the longitudinal direction; and the top beam consists of a top plate, two lower vertical plates fixed on the lower surface of the top plate at intervals along the longitudinal direction, and multi-layer arc plates fixed on the two sides of the two lower vertical plates along the longitudinal direction. The hydraulic support has the advantages that the traditional box structure is radically changed, so that the aim of light weight is fulfilled.
Description
technical field [0001] The invention relates to a mine hydraulic support structure, in particular to a thin-shell type hydraulic support. Background technique [0002] A large number of hydraulic supports are used in the coal mine industry. Although there are many types, the main components include three major parts, namely: base, cover beam, and roof beam. Although the structural form of each part is different in detail, they are all box-type structures. Its shortcomings are mainly manifested in three aspects: 1. It needs to use a large amount of high-strength steel; 2. Due to its heavy weight, it is difficult to carry; 3. The bearing strength is limited. Contents of the invention [0003] The purpose of the present invention is to provide a light-weight thin-shell hydraulic support under the premise of ensuring the support strength. [0004] To achieve the above object, the present invention takes the following technical solutions: [0005] The thin-shell type hydraul...
