Abstract

The utility model provides a modular-type hydraulic bracket, which belongs to the supporting device for coal mining in coal mine, and comprises a basic module and a specification module, wherein, the basic module consists of a top beam (1), a base (2), an upright post (3), a jack (4), a swinging rod (5) and a swinging rod seat (6); the specification module consists of a heightened block (9) and a lengthened section (8); and the modular-type hydraulic bracket also comprises a functional module which consists of a tail beam (7) and accessories; for the bracket with the same work resistance, the basic module is constant, and the functions of the bracket can be changed by replacing different functional modules, so that any brackets such as supporting shielding form, top form, and the like can be assembled; by increasing and reducing the specification module, on the premise of ensuring that the function of the bracket is constant, the maximum supporting height of the bracket can be changed. The bracket has the advantages of flexibility, wide application, small size, light weight, large supporting strength, convenient transportation and installation, low price, and the like.

Description

A kind of modular hydraulic support
Technical field
The utility model relates to a kind of support apparatus in coal mine, is specially a kind of hydraulic support.
Background technology
The coal mining supporting is the Safety of Coal Mine Production critical facility.Existing support pattern mainly contains three kinds: 1. hydraulic prop, 2. fully mechanized mining supporter, 3. simple rack (containing suspended, catenary suspension, combined type etc.).Low, the light and flexible of individual prop cost once was used widely, and belonged to third generation supporting product, and with respect to the wooden prop and the metal friction pillar in one or two generations, it is constant to have working resistance, fast and flexible, advantage such as safe and reliable.But along with the fast development of coal-mining technique, its shortcoming also comes out gradually, and working resistance is little, and supporting intensity is low, and it is slow to move frame, and production efficiency is low, and it is substituted by advanced more fully mechanized mining supporter in coal production more and more.It is big that fully mechanized mining supporter has working resistance, safety factor is big, the supporting intensity height, the production efficiency advantages of higher, but the body that it is huge, bigger weight, and higher manufacturing cost, use at some medium and small collieries is subjected to certain limitation, especially in local and private colliery, be subjected to span length, promote the restriction of transport capacity and fund, and can't use, simple rack is an a kind of type between support unit and fully mechanized mining supporter, on safety, though than individual prop raising is arranged on the efficient, but greatly differ from each other with respect to fully mechanized mining supporter, top-heavy, safety is its outstanding defective inadequately, though light, cost performance is not high.Therefore such support is eliminated at last as the transiens support, and prospect is bad.
Summary of the invention
In order to solve above technical problem, the utility model spy provides that a kind of size is little, in light weight, supporting intensity big, convenient transportation, cost are low, use modular hydraulic support flexibly.
For achieving the above object, the technical scheme that the utility model is taked is:
A kind of modular hydraulic support, comprise basic module, specification module, functional module composition, basic module includes back timber, base, column, jack, fork, swing rod composition, the specification module by connect high piece, lengthening section is formed, functional module is made up of tail boom and annex, the upper end of column and the upper end of tail boom are all hinged with back timber, the lower end of column with connect high piece upper end and be connected, the lower end that connects high piece connects with base, the tail boom upper end is hinged with the back timber end, tail boom lower end and fork upper end are hinged, and fork and swing rod are hinged, and swing rod connects with lengthening section.
The tail boom of this modular hydraulic support is covered formula tail boom or caving coal formula tail boom for propping up.
This modular hydraulic support resolves into three kinds of modules with the support of same working resistance, pass through optimal design, 1.5 meters, 1.25 meters that center to center distance between each support is existing popular change 1 meter into, make its lightweight, standardization, reduced the supporting area, improve supporting intensity, alleviated weight, reduced cost; Basic module is general, changeless, by changing function and the purposes that functional module changes support, change the maximum supporting height of support by the increase and decrease module, it is general that modularized design is able to most of component of polytype support, helps producing in batches, helps management.
Therefore, the utlity model has advantages such as flexible and changeable, of many uses, that size is little, in light weight, installation and transportation convenient, supporting intensity is big, cost is low.
Description of drawings
Fig. 1 is the utility model example structure schematic diagram.
The specific embodiment
As shown in drawings: 1, back timber, 2, base, 3, column, 4, jack, 5, fork, 6, swing rod, 7, tail boom, 8, lengthening section, 9, connect high piece.
A kind of modular hydraulic support, comprise basic module, the specification module, functional module is formed, basic module includes back timber 1, base 2, column 3, jack 4, fork 5, swing rod 6 is formed, the specification module is by connecing high piece 9, lengthening section 8 is formed, functional module is made up of tail boom 7 and annex, the upper end of the upper end of column 3 and tail boom 7 is all hinged with back timber 1, the lower end of column 3 with connect high piece 9 upper ends and be connected, the lower end that connects high piece 9 connects with base 2, tail boom 7 upper ends and back timber 1 are terminal hinged, tail boom 7 lower ends and fork 5 upper ends are hinged, and fork 5 is hinged with swing rod 6, and swing rod 6 connects with lengthening section 8.
The tail boom 7 of this modular hydraulic support is covered formula tail boom or caving coal formula tail boom for propping up.
This modular hydraulic support resolves into three kinds of modules with the support of same working resistance, pass through optimal design, 1.5 meters, 1.25 meters that center to center distance between each support is existing popular change 1 meter into, make its lightweight, standardization, reduced the supporting area, improve supporting intensity, alleviated weight, reduced cost; Basic module is general, changeless, by changing function and the purposes that functional module changes support, change the maximum supporting height of support by the increase and decrease module, it is general that modularized design is able to most of component of polytype support, helps producing in batches, helps management.
