Problems solved by technology

[0002] In coal mine mining, single hydraulic props are often used to support the mining face. However, for the single props currently used for coal mine support, there has always been a common problem that it is difficult to decompress and unload the single hydraulic props. Greatly reduces work efficiency

Embodiment 1

[0017] This embodiment provides a decompression and unloading type single pillar base mechanism, which includes a base plate 1, a fixed wedge-shaped support 2 and a movable wedge-shaped support 3, and two parts of the fixed wedge-shaped support 2 and the movable wedge-shaped support 3 Each end is respectively provided with an ear buckle 6, the height of the ear buckle 6 at both ends of the fixed wedge-shaped support block 2 is different from that of the two ends of the movable wedge-shaped support block 3, and the fixed wedge-shaped support block 2 and the movable wedge-shaped support block 3 are symmetrical. Set, the ear buckles 6 at both ends of the fixed wedge-shaped support block 2 overlap with the ear buckles 6 at the two ends of the movable wedge-shaped support block 3, and are connected by the screw rod 4 and the nut 5 at the ear buckle 6 places.

[0018] The upper end surface of the fixed wedge-shaped support block 2 and the upper end surface of the movable wedge-shaped...

Embodiment 2

[0020] This embodiment has made a further improvement on the basis of the first embodiment, which includes all the content of the first embodiment, that is, the decompression and unloading single pillar base mechanism in this embodiment includes the decompression and unloading of the first embodiment. All the structural features of the type single-pillar base mechanism, the specific improvements are as follows:

[0021] Such as figure 1 and figure 2 As shown, the fixed wedge-shaped support block 2 and the upper semi-conical surface of the movable wedge-shaped support block 3 of the decompression and unloading single support base mechanism in this embodiment are provided with semicircular gaps on the side close to the other wedge-shaped support block. The fixed wedge-shaped support block 2 and the movable wedge-shaped support block 3 are symmetrically arranged and connected together by bolts and nuts 5 to form a combination. A cylindrical hole 8 is formed in the center of the...

Abstract

The invention discloses a base mechanism of a decompression unloading-type single prop. The base mechanism comprises a base bottom plate and two wedge-shaped support blocks. One of the wedge-shaped support blocks serves as a fixed wedge-shaped support block to be welded onto the base bottom plate, and the other wedge-shaped support block serves as a movable wedge-shaped support block to be connected with the fixed wedge-shaped support block through a screw rod and a nut. The base mechanism has the advantages that the single prop can be effectively decompressed and unloaded, or shrunk and demounted; the base mechanism is simple in structure, convenient to operate, and good in application effect; the technical problem of difficulty in decompression unloading of the single prop in the field is solved; the base mechanism has extensive practicability in the technical field.

Description

technical field [0001] The invention relates to the technical field of base mechanisms, in particular to a single-pillar base mechanism capable of decompression and unloading. Background technique [0002] In coal mine mining, single hydraulic props are often used to support the mining face. However, for the single props currently used for coal mine support, there has been a common problem of decompression and unloading of single hydraulic props. Work efficiency is greatly reduced. Contents of the invention [0003] The object of the present invention is to provide a decompression and unloading type single pillar base mechanism to solve the above-mentioned problems in the prior art and facilitate the decompression and unloading of the single pillar. [0004] In order to achieve the above object, the present invention provides the following solution: The present invention provides a decompression and unloading type single pillar base mechanism, which includes the bottom pl...
