Abstract
The invention discloses a guide rail for a rock drilling equipment thruster. The guide rail comprises an upper guide rail (1) and a lower guide rail (6), wherein the guide rail is integrally prepared by deformation processing through a round steel pipe; an upper groove (2) is formed in the middle of the upper guide rail; symmetrically connected guide slopes are respectively formed at two ends of the upper guide rail; a lower groove (5) is formed in the middle of the lower guide rail; symmetrically connected guide slopes are respectively formed at two ends of the lower guide rail; a cavity (8) is formed between the upper guide rail and the lower guide rail. The guide rail determines the wall thickness and the diameter of the round steel pipe according to the rail wall thickness and the wall length of a guide rail section; by die pressing, the round steel pipe is converted into the integrated guide rail with the inner hollow structure; the integrated manufacturing technology is simple, and the weight is light; welding materials and welding cost are saved; the production cost is reduced; moreover, inner stress deformation caused by welding can be avoided, so that the guide rail linearity can not be reduced; therefore, the usability of rock drilling equipment is improved.
Description
Technical field
The present invention mainly is applicable to tunnel, the tunnel in the fields such as colliery, metallurgy, water power, railway, highway, excavation and the driving of culvert, relates in particular to a kind of propeller guide rail that straightness accuracy is had relatively high expectations.
Background technology
In the colliery, the tunnel such as metallurgy, water power, in the tunnel piercing operation process, the rock drilling equipments such as jumbo are a kind of engineering equipments commonly used.The most of full hydraulic drive that adopts of rock drilling equipment adopts the crawler travel mode, working stability, and climbing capacity is strong.Hydraulic rock mechanism all can the rock drilling operation to work plane, top board, lateral wall, the base plate in tunnel flexibly.Thruster of jumbo partly is the main functional parts of jumbo.In the prior art, institute's employing guide rail adopts section bar or Plate Welding to form usually on most of rock drilling equipments, then process correction, use required precision to reach, there is following technical problem in the guide rail of this structure: welding procedure is complicated, for the degree of accuracy that guarantees to weld, need to adopt more frock; Because solder joint is more, after the frock of dismantling, whole guide rail can deform under the effect of internal stress, can not well guarantee the straightness accuracy of guide rail.Being that 2011200421591 patent application adopts upper rail and the lower guideway of moulding to be welded such as application number, is that 2008201276856 utility application also adopts the left rail of moulding and right guide rail to be welded by the intermediate rectangular body such as application number.All there is above-mentioned technical problem in these two patent applications.
Summary of the invention
With the existing problem of guide rail, the invention provides a kind of hollow structure guide rail of making by deformation processing integral body with round steel pipe for rock drilling equipment in the above-mentioned prior art.
The technical scheme that the technical problem to be solved in the present invention is taked is: described rock drilling equipment propeller is made by deformation processing integral body with round steel pipe with guide rail, it comprises upper rail and lower guideway, described upper rail centre has upper groove, the upper rail two ends have respectively the guiding surface that symmetrical expression links to each other, described lower guideway centre has low groove, the lower guideway two ends have respectively the guiding surface that symmetrical expression links to each other, and are formed with cavity between described upper rail and the lower guideway.
For preventing being out of shape in use than long guideway, be fixedly installed locating piece at the guide rail two ends.
Wall thickness and diameter that the present invention determines round steel pipe according to rail wall thickness and the wall length in guide rail cross section, make round steel pipe become the inner monolithic guide rail of cavity structure that is by mold pressing, integral body makes that not only technique is simple, lightweight, save welding material and welding expense, reduce production costs, and can avoid welding to produce the internal stress distortion and the reduction guide rail linearity, improved the service efficiency of rock drilling equipment.

Fig. 2 is the A-A sectional structure schematic diagram of Fig. 1.
In the drawings, 1, upper rail 2, upper groove 3, upper plate 4, lower shoe 5, low groove 6, lower guideway 7, locating piece 8, cavity.
The specific embodiment
In Fig. 1 and Fig. 2, described rock drilling equipment propeller is made by deformation processing integral body with round steel pipe with guide rail, it comprises upper rail 1 and lower guideway 6, has upper groove 2 in the middle of the described upper rail, the upper rail two ends have respectively the guiding surface of symmetrical expression, tool low groove 5 in the middle of the described lower guideway, the lower guideway two ends have respectively the guiding surface of symmetrical expression, be formed with cavity 8 between described upper rail and the lower guideway, link to each other by a upper plate 3 with flanging between the guiding surface at upper rail two ends, lower shoe 4 direct and straight between the guiding surface at lower guideway two ends links to each other.Track cross-section as shown in Figure 2, this guide rail comprises up and down two grooves, can place the associated components such as the driver part such as oil cylinder and hydraulic valve in the groove structure.This guide rail is the cavity structure, is formed by the round steel pipe deformation processing, has avoided welded construction to cause guide rail to affect the shortcoming of the straightness accuracy of guide rail owing to internal stress.The up and down two ends of two sides are guiding surface about this guide rail, for the slip of slide unit on guide rail and the guide rail provides guide effect.Wall thickness and the diameter of determining round steel pipe according to rail wall thickness and the wall length in upper/lower guide cross section, make round steel pipe become the inner monolithic guide rail of cavity structure that is by mold pressing, in order to prevent the distortion than long guideway, in the two ends of guide rail, be welded and fixed and be provided with locating piece 7, the distortion that locating piece can prevent rail end is set, guarantees better the track straightness accuracy; And the location and installation that is conducive to other component on the track.
Claims (2)
1. rock drilling equipment propeller guide rail, it comprises upper rail (1) and lower guideway (6), it is characterized in that: described guide rail is made by deformation processing integral body with round steel pipe, described upper rail centre has upper groove (2), the upper rail two ends have respectively the guiding surface that symmetrical expression links to each other, described lower guideway centre has low groove (5), the lower guideway two ends have respectively the guiding surface that symmetrical expression links to each other, and are formed with cavity (8) between described upper rail and the lower guideway.
