Technical field
The utility model relates to rock drilling equipment technical field, particularly a kind of mine drilling driving forward beam.
Background technology
Jumbo is a kind of rock drilling equipment of the drill bursting construction that tunnels and underground engineering adopts, and it can move and support that multiple stage rock drilling machine carries out drilling simultaneously.Jumbo mainly contains the ancillary service of hammer drill, drill boom (support of rock drilling machine, location and propulsive mechanism), steel work vehicle frame, running mechanism and other necessity, and formed according to the equipment that requirement of engineering is added.
At present, hydraulic drill ring development is very fast, and it not only makes rock drilling mechanization of operation, and expands the scope of application of hammer drill, and progressively to rock drilling automation development.Increasing people starts production efficiency and the stability of focusing on jumbo in recent years, propeller is one of important composition parts of jumbo equipment, now conventional forward beam majority is steel work, need welding processing, exist welding interior stress distortion and welding stress remain etc. weld defect, cause the intensity of forward beam greatly to reduce, equipment failure rate is more, affects construction speed.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of mine drilling driving forward beam, its structure is simple, making is easy, intensity is high, lightweight, can avoid weld defect, the fault rate of effective reduction equipment, extend the application life of forward beam, reduce cost of manufacture.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of mine drilling driving forward beam, comprise body pillar, described body pillar is U-type groove structure, four guide ribs are up and down outside symmetrical point of two upper ends being located at body pillar and bottom land, the coated one deck wearing plate of external surface of described each guide rib, described body pillar and four guide ribs are structure as a whole, be provided with boss outside facade between two vertical guide ribs, the height of described boss is less than the thickness of coated wearing plate; The inner side of each guide rib is provided with groove, and one end button of described wearing plate hangs on the groove of the inner side of guide rib, and the boss place of one end outside facade that a pair vertical wearing plate is adjacent passes through bolt presses.
Further, described wearing plate adopts abrasion-proof stainless steel cold moudling.
Further, boss is provided with briquetting, described bolt compresses described a pair wearing plate vertically through briquetting.
Further, described body pillar and four guide ribs are the integrative-structure adopting hard aluminium alloy hot extrusion molding.
The beneficial effect adopting technique scheme to produce is:
1. U-shaped body pillar of the present utility model is the integrative-structure with hard aluminium alloy hot extrusion molding, and whole U-shaped body pillar is lightweight, intensity is high, can ensure straightness accuracy requirement preferably.
2. the wearing plate that U-shaped body pillar guide rib external surface is coated is shaped with ganoid abrasion-proof stainless steel plate cold forming, and flatness precision is high, and friction factor is less, and cost is lower.
3. in the utility model, wearing plate one end is pressed on the guide rib of body pillar by circular arc, and buckle on the groove inside guide rib, what the design of groove made wearing plate can automatic impaction and without the need to compressing with other parts again, its another side is pressed on the facade of body pillar by briquetting, wherein the height of boss is lower than the thickness of wearing plate, ensures the reliability compressed.
The utility model structure is simple, making is easy, intensity is high, lightweight, can avoid weld defect, the fault rate of effective reduction equipment, extend the application life of forward beam, reduce cost of manufacture.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
See Fig. 1, Fig. 2, Fig. 3, body pillar 1 is U-shaped structure, it is the main body carrying whole propulsive mechanism, body pillar 1 comprises four laterally zygomorphic guide ribs 11, groove 12 and the boss 13 be located at outside two facades of guide rib 11 medial surface, described guide rib 11 adopts upper and lower symmetrical structure to facilitate the processing of other part on wearing plate 2 and propulsive mechanism, body pillar 1 arranges four the same guide ribs 11, facilitate the component with its connection, reduce cost of production, the design of described groove 12 ensure that wearing plate 2 has the space of adduction in shape on one side, enable wearing plate 2 one side automatic impaction and without the need to compressing with other parts again, body pillar 1 is U-shaped structure, ensure that the middle part of body pillar 1 has enough space to place other component of propulsive mechanism, is convenient to the compact design of propulsive mechanism, the design of described boss 13 reduces the difficulty of processing of wearing plate 2 and briquetting 3, the thickness of the aspect ratio wearing plate 2 of boss 13 is slightly little, ensure that wearing plate 2 can be compacted, two guide ribs 11 below described body pillar 1 form a channel space, the bottom of body pillar 1 is made to have enough spaces to place other coupled component, enable propulsive mechanism compacter, whole body pillar 1 is lightweight, intensity is high, adopts hot extrusion technique and symmetrical structure can ensure straightness accuracy requirement preferably.
Wearing plate 2 is shaped with ganoid abrasion-proof stainless steel plate cold forming, and flatness precision is high, and friction factor is less, and cost is lower.Two pieces of wearing plates 2 adjacent while be pressed on body pillar 1 by briquetting 3 facade outside, described briquetting 3 is fixedly installed on the boss 13 of body pillar 1 by bolt 4 and packing ring 5.
In real work; the propelling cylinder of rock drilling machine is arranged in the U-type groove of body pillar 1; the external surface of guide rib 11 is slip work plane; the slip work plane of wearing plate 2 pairs of guide ribs 11 plays a very good protection; and change also than being easier to after wearing plate 2 serious wear, wherein, rock drilling machine is arranged on the upper end of body pillar 1 by upper leading truck; its lower end is connected by the arm body of lower leading truck with equipment such as jumboes, thus realizes the propelling of rock drilling machine on forward beam.
Body pillar 1 of the present utility model and wearing plate 2 are all extruded, technique is simple, intensity is high, lightweight, need not weld, avoid welding interior stress distortion and welding stress remain etc. defect, also reduce cost simultaneously.
The utility model is not limited to above-described embodiment; to those skilled in the art; the any apparent improvement make above-described embodiment of the present utility model or change, all can not exceed the protection domain of the embodiment of the present utility model and claims only illustrated by way of example.
