Abstract

The utility model relates to the technical field of coal mine underground monomer pillars, and discloses a mining shed lifting support which comprises a top beam (1), a sill beam (2), upright posts (3) and a pin shaft (4), wherein the top beam (1) is connected to the sill beam (2) by two upright posts (3) through two positions on the top beam (1), which are close to the two ends of the top beam (1), as well as two positions on the sill beam (2), which are close to the two ends of the sill beam (2); and each upright post (3) is provided with a hydraulic system (12). The mining shed lifting support provided by the utility model is suitable for supporting to up and down lane crossheading top plates as well as supporting to an end region of a working face. According to the utility model, temporary supporting to the lane top plates can be achieved, a lifting jack is adopted for connection between two racks, self moving can be achieved, and the mounting and the dismounting are convenient. The problem of bad monomer pillar supporting effect is solved, self moving is achieved, and the labor intensity of workers is relieved greatly.

Description

The mining canopy support of lifting
Technical field
The utility model relates to individual prop technical field under the coal mine, is particularly useful for the supporting of lane crossheading top board up and down and a kind of mining canopy support of lifting of face end zone supporting.
Background technology
At present, some collieries are thrown away the suitable monomers pillar and are carried out supporting, and supporting effect is poor, and the dismantlement work amount is big, and production efficiency efficient is low, and have very big potential safety hazard.
Summary of the invention
For solving the problem of individual prop supporting effect difference, the utility model provides a kind of mining canopy support of lifting.Can provide secure support to top board, can cooperate U-shaped girder steel to be suitable for, connect by passing jack between support, can realize having alleviated labor strength greatly from moving.
In order to realize the foregoing invention purpose, the utility model adopts technical scheme as follows:
A kind of mining canopy support of lifting comprises: back timber 1, bottom girder 2, column 3, bearing pin 4, described back timber 1 locate to be connected near two ends by two columns 3 and bottom girder 2 respectively near two ends places; Each column 3 is provided with hydraulic system 12.
A kind of mining canopy support of lifting, described back timber 1 are connected by bearing pin 4, cottor pin 5, packing ring 8 fixedly connected with column 3 upper ends.
A kind of mining canopy support of lifting, described bottom girder 2 are connected by bearing pin 6, packing ring 7 fixedly connected with column 3 lower ends.
A kind of mining canopy support of lifting, the two ends of described bottom girder 2 are provided with bearing pin 9 holes that are connected with connecting rod.
A kind of mining canopy support of lifting, described back timber 1 bearing height is 2.2-3.9m, the support works resistance is 2200KN.
A kind of mining canopy support of lifting, described back timber, bottom girder are connected with column and are cylinder and connect.
Owing to adopt aforesaid technical scheme, the utlity model has following superiority:
A kind of mining canopy support of lifting is the modifying device of individual prop under the coal mine, is applicable to the supporting of lane crossheading top board up and down and the supporting in face end zone.Can realize the temporary lining to back, connect with jack between two, can realize installing and convenient disassembly from moving.Solved the problem of individual prop supporting effect difference, can realize having alleviated labor strength greatly from moving.
The utility model back timber, bottom girder have increased and connect the top and connect floor space, have reduced specific pressure, have guaranteed supporting effect, by wiping the top from moving, have alleviated manipulation labour intensity, have guaranteed the supporting safety.
Description of drawings
Fig. 1 is the mining canopy supporting structure schematic diagram of lifting;
Among the figure: 1, back timber; 2, bottom girder; 3, column; 4, bearing pin; 5, cottor pin; 6, bearing pin; 7, packing ring; 8, packing ring; 9, bearing pin; 10, packing ring; 11, B shape pin; 12, hydraulic system.
The specific embodiment
As shown in Figure 1, a kind of mining canopy support of lifting comprises: back timber (1), bottom girder (2), column (3), bearing pin (4), described back timber (1) locate to be connected near two ends by two columns (3) and bottom girder (2) respectively near two ends places; Each column (3) is provided with hydraulic system (12).
Described back timber 1 and column (3) upper end is connected that to pass through bearing pin (4), cottor pin (5), packing ring (8) fixedly connected.
Described bottom girder 2 is connected by bearing pin (6), packing ring (7) fixedly connected with column (3) lower end.
The two ends of described bottom girder 2 are provided with bearing pin (9) hole that is connected with connecting rod.
The utility model back timber is given bottom girder by column with the pressure place of production, and back timber, bottom girder all adopt cylinder to be connected with column, guarantees the support lateral stability.Back timber bearing height 2.2-3.9m, working resistance 2200KN.
The utility model is transported to support needs the supporting position, makes highly pressurised liquid enter the column cavity of resorption by the control control valve, and support is risen to and the tight Support Position of top board, realizes top board is supported effectively.In the time of need moving frame, by control valve column is shunk, back timber and top board are broken away from, pass jack by control support is moved.
