Abstract
The utility model discloses a push rod used for thin coal seam mining bracket. The push rod comprises a push rod body, a bracket connection structure and a conveyor connection structure. The push rod body adopts an integer plate-type structure. The push rod of the utility model is suitable for the thin coal seam mining bracket and has the advantages of simple structure, lower manufacturing cost, high strength and suitability to be used with the hydraulic bracket base with compact structure.
Description
Technical field
The utility model relates to the coal mining apparatus field, especially relates to a kind of push rod that is used for the thin seam mining support.
Background technology
In the hydraulic support of coal mining equipment, push rod is positioned at neutral gear place in the middle of the base, be placed on the base plate, and with pass jack and connector by the bearing pin composition push unit that is connected, to realize the reach of support self and transporter.Because the geological conditions complexity makes that the hydraulic rack structure form is various, is subjected to the influence of many uncertain factors, causes various informativeization of push rod.Existing push rod can be divided into long push rod and short push rod two big classes by form, no matter is long push rod or short push rod, generally is the box structure that is formed by the steel plate assembly welding.Yet, mining height is extremely low during thin seam mining, workman's walking space is less, entire bracket all requires parts simplified design under situation about meeting the demands everywhere, and the understructure of general in this case thin seam mining support is all compact, and can not finely the mating of the push rod of body structure form and base, and the push rod manufacture craft relative complex of existing body structure, cost is higher, therefore, needs a kind of simplification push rod that is applicable to the thin seam mining support of design.
The utility model content
In view of this, the purpose of this utility model is to provide a kind of push rod that is used for the thin seam mining support, and it is simple in structure, cost of manufacture is lower, and the intensity height is suitable for being used with the hydraulic support foundation of compact conformation.
For achieving the above object, the utility model by the following technical solutions:
The push rod that is used for the thin seam mining support of the present utility model comprises push rod main body, support draw bail and transporter draw bail, and described push rod main body adopts whole plank frame.
Further, the thickness of described push rod main body is 55-65mm.
Further, the thickness of described push rod main body is 60mm.
Further, described support draw bail comprises two parallel risers that are arranged on push rod one end, and cotter way is set on the riser; The bottom of riser is provided with guide strip.
Further, the yield strength of the alloy steel that described push rod adopted is 645-690Mpa.
The beneficial effects of the utility model are: push rod of the present utility model is when design, fully take into account support pedestrian's in the coal mining process convenience, understructure is arranged under the compact situation, satisfying the support pushing and sliding, move on the basis of frame desirable strength, courageously break through conventional, the body design of push rod has been abandoned traditional body structure, and adopt whole plank frame, promptly use the high-intensity slab of a monoblock, as the connecting rod between support and the transporter, realize the pushing and sliding of equipment, move the frame action, push rod of the present utility model is the intensity height not only, long service life, when being suitable for thin seam mining and the hydraulic support foundation of compact conformation be used, and its decoration structure features simple design, save steel, simplified technology, reduced manufacturing cost.
Other advantages of the present utility model, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on being conspicuous to those skilled in the art, perhaps can from practice of the present utility model, obtain instruction to investigating hereinafter.Target of the present utility model and other advantages can be passed through following manual, claims, and the specifically noted structure realizes and obtains in the accompanying drawing.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
As depicted in figs. 1 and 2, the push rod that is used for the thin seam mining support of present embodiment, comprise push rod main body 1, support draw bail and transporter draw bail 2, described push rod main body 1 adopts whole plank frame, and push rod main body 1 is the alloy steel steel plate that a thickness is 60mm when promptly implementing; Described support draw bail comprises two parallel risers 3 that are arranged on push rod one end, and cotter way 5 is set on the riser; Guide strip 4 is arranged at the bottom of riser.Each parts of push rod all adopt the alloy steel manufacturing, and the yield strength of the alloy steel of employing is 660-690Mpa.
The pusher structure that is used for the thin seam mining support of present embodiment is with the push rod of embodiment 1, and different is that push rod main body 1 is the alloy steel steel plate that a thickness is 65mm, and the yield strength of the alloy steel that each parts of making push rod all adopt is 645-660Mpa.
Push rod among embodiment 1 and the embodiment 2 is intensity height, long service life only, when being suitable for thin seam mining and the hydraulic support foundation of compact conformation be used, and its decoration structure features simple design has been saved steel, has simplified technology, has reduced manufacturing cost
Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, other modifications that those of ordinary skills make the technical solution of the utility model or be equal to replacement, only otherwise break away from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of the claim scope of the present utility model.
