Abstract
The invention relates to timbering equipment with the function of timbering an underground mining working face, which can move with the motion of the working face. The equipment mainly comprises a suspension mechanism, top beams, a hydraulic prop, a hydraulic thrust cylinder and other components; two or more suspension devices arranged on two sides of a support are connected with the supports on two sides respectively; two ends of the thrust cylinder are connected with the suspension devices and the top beams respectively; and the hydraulic prop is vertically connected with the lower ends of the top beams respectively. When in work, one end of the thrust cylinder is connected with the suspension mechanism, while the other end is connected with the top beams, and the adjacent top beams are connected with each other through the suspension mechanism to make a plurality of the top beams connected into a group of integral combined supports so as to improve the stability of the timbering equipment and the adaptability of the timbering equipment and ensure that the motion of the supports becomes faster and more convenient. The timbering equipment is not only used for a blasting working face, but also used for a machine mine working face.
Description
Technical field
The present invention relates to a kind of support apparatus that uses at the underground mining work plane, particularly a kind of sectional shelf-unit that moves that is used under the coal mine with stope.
Background technology
At present, the existing support apparatus of home and abroad colliery underground mining work plane is divided into stand alone type and combined type, can be divided on the move mode: plug-type, crawler type, step type and sliding.Above-mentioned several form support is not suitable for the thin big work plane of work plane, pressure in the bigger work plane in inclination angle, the softer work plane of base plate, coal seam, in the use of breaking roof work plane or top-coal caving face, also to lay and protect the top wire lath at top of the trellis, therefore exist the scope of application little, use the high shortcoming of cost.Composite retaining structure equipment has joist usually in addition, and the support apparatus of band joist can't adapt to the use of girdle.
Summary of the invention
The purpose of this invention is to provide a kind of sectional shelf-unit that in the work plane that high inclination-angle, soft seat, coal seam approach, pressure is big, uses, it can make some back timbers form a cover combination supporting equipment by the connection of suspension arrangement, even at breaking roof work plane, top-coal caving face, use less than 3 meters local empty top work planes, because the gap between support need not re-lay wire lath less than 100 millimeters.
A kind of technical scheme provided by the present invention is: a kind of suspended combined support, form by hitch, back timber, hydraulic prop and hydraulic pressure propulsion cylinder, two or more suspension arrangement by the support both sides that are placed in is connected with two side stands respectively, the two ends of propulsion cylinder are connected with back timber with suspension arrangement respectively, and hydraulic prop is vertically connected on the lower end of back timber respectively.
Further, suspension arrangement is placed in vertical both sides slideway of back timber.
Further, suspension arrangement and two side stands can be fixed or be slidingly connected.
Advantage of the present invention is: good integrity when being used in combination, compliance is strong, stability is high, and is convenient, fast when needs are mobile, can be synchronous with coal-winning machine.Each support is by the suspension arrangement combination that is connected, and rate of extraction height can use at thin seam working surface.

The specific embodiment
In conjunction with example the present invention is done following detailed description with reference to the accompanying drawings.
One, support is formed
With reference to Fig. 1, Fig. 2 and Fig. 3, the member that back timber 3 is made up of frame construction, suspension arrangement 1 is connected with the both sides back timber, and hydraulic prop 4 vertically places respectively below the back timber 3, and propulsion cylinder 2 is connected with back timber 3 with suspension arrangement 1 respectively.
Two, install
When equipment is installed, support is arranged successively with the exploitation work plane, suspension arrangement 1 is installed successively, back timber is supported on the seam roof the fluid injection of hydraulic prop 4.
Three, the operation of moving one's steps
With reference to Fig. 4, to the hydraulic prop discharge opeing under the back timber 3, carry post, back timber 3 is vertically descended, this moment, this back timber hung between the back timber of both sides.
With reference to Fig. 5, to two propulsion cylinders, 2 fluid injections simultaneously of same back timber, because the front end of propulsion cylinder is connected with the slip side of suspension arrangement, the tail end of propulsion cylinder is connected with back timber, make back timber 3 along direction of arrow reach, move the back, this back timber 3 is supported on the roof again the pillar fluid injection.
With reference to Fig. 5, to the hydraulic prop discharge opeing under the back timber 3, carry post, back timber 3 is vertically descended, this moment, this back timber hung in the middle of the back timber of both sides.
With reference to Fig. 6, to 2 fluid injections simultaneously of two propulsion cylinders, because the front end of propulsion cylinder is connected with the slip side of suspension arrangement, the tail end of propulsion cylinder is connected with back timber, make back timber 3 along direction of arrow reach, move the back, this back timber 3 is supported on the roof again the pillar fluid injection.
Claims (3)
1, a kind of suspended combined support, form by hitch, back timber, hydraulic prop and hydraulic pressure propulsion cylinder, it is characterized in that: the two or more suspension arrangement (1) by the support both sides that are placed in is connected with two side stands respectively, the two ends of propulsion cylinder (2) are connected with back timber (3) with suspension arrangement (1) respectively, and hydraulic prop (4) is vertically connected on the lower end of back timber (3) respectively.
2, suspended combined support according to claim 1 is characterized in that: suspension arrangement (1) is placed in vertical both sides slideway of back timber (3).
