Abstract
The utility model discloses a moving mechanism for a rotary table of a mechanical arm frame for spraying concrete, comprising an arm frame rotary table rack, which is characterized in that the moving mechanism further comprises a transverse H-shaped traveling track; moving rollers are disposed in clamping grooves along both sides of the travelling track on the arm frame rotary table rack; a thrust oil cylinder connected with a main machine is disposed on the arm frame rotary table rack; and safety stoppers for limiting movement of the arm frame rotary table rack are disposed at both ends of the travelling track. The utility model can solve the problem of over-large contact stress between the rollers and the track of the arm frame rotary table rack.
Description
Technical field
The utility model belongs to technical field of engineering machinery, particularly relates to a kind of travel mechanism that is used for the concrete sprayer tool arm frame panoramic table of constructing tunnel.
Background technology
In recent years, along with Ministry of Railways's mine construction method is progressively implemented in China, rebound degree is low, reliability is high because the tunnel concrete jet robot has, high safety, and characteristics such as labour intensity is low begin to be widely used among all kinds of railway tunnel constructions.
The spray regime of concrete sprayer is one of this machine Specifeca tion speeification, because in the operating mode complexity, in the not good tunnel of ground out-of-flatness, light, increases and sprays coverage, can reduce the walking number of times, saves time, and increases work efficiency.Jib panoramic table horizontal mobile mechanism can realize increasing the purpose of spray regime under the situation that does not increase jib length.
The horizontal mobile mechanism of at present existing jib panoramic table adopts 4 rollers to be distributed in the channel suspending rail usually, and by calculating, this kind structure is used for spraying machine, and its maximum contact stress has surpassed 1600Mpa, and common welding material is difficult to meet the demands.And the walking mechanism of this structure is adopted in evidence, and after jib revolution stand moved around 100 hours, tangible indenture and tired spot corrosion appearred in the track upper and lower surface that contacts with roller.
The utility model content
Technical problem to be solved in the utility model provides a kind of travel mechanism that can solve the excessive concrete sprayer tool arm frame panoramic table of roller and track contact stress.
In order to address the above problem, the utility model has been taked following technical scheme: the travel mechanism of concrete sprayer tool arm frame panoramic table comprises jib revolution stand, I shape walking track; Be provided with shifting roller in described jib revolution stand upper edge walking track two side bayonet slots, jib revolution stand is provided with the propelling oil cylinder that is connected with main frame, and the two ends of walking track are provided with and are used to limit the safety catch that jib panoramic table frame moves.
Described shifting roller is to combine with compound roller bearing of standard and installation seat plate.Wherein installation seat plate is fixed on the jib revolution stand, and the bearing centre axle is fixedlyed connected with installation seat plate, and outstanding little runner is equipped with in compound roller bearing side.
The roller scraper plate is installed on the described jib revolution stand to be placed in walking track two side bayonet slots before and after the shifting roller.
Described safety catch is made up of steel plate and rubber spring.
Compared with prior art, the travel mechanism that provides of the utility model has following beneficial effect:
1) this travel mechanism adopts the I shape track, increases to 4 stressed tracks by original 2 stressed tracks, thereby can arrange 1 times the shifting roller that contacts with stressed track more, has reduced contact stress, can advancing the track and application life of roller.
2) outstanding little runner has been installed in the shifting roller side, rotates voluntarily when contacting with riser in the middle of the walking track, has prevented jib revolution stand in the generation along sideslip stuck phenomenon in the track travel process, guarantees that it is current smoothly.
3) walking track two ends are equipped with the safety catch with pooling feature, can limit the motion atmosphere of jib panoramic table frame, prevent the danger that oil cylinder damages or revolution stand in fracture back marks track together with jib, and are safe and reliable.To the impact of jib and oil cylinder, increased the mobile device stationarity when pooling feature reduces the stand contact blocks simultaneously.
The utility model proves that by the site trial of a period of time this cover mechanism can steadily finish jib moving forward and backward when work reliably, finishes the spray regime of desired design smoothly.And track without any obvious polishing scratch, reaches instructions for use after construction a period of time.
Below in conjunction with drawings and Examples the utility model is described further.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a drawing in side sectional elevation of the present utility model.
Fig. 3 is the structural representation of shifting roller in the utility model.
The specific embodiment
As shown in Figure 1 and Figure 2, the utility model comprises jib revolution stand 3, two I shape walking tracks 2 and shifting rollers 4; Wherein respectively walk and be provided with 4 groups of shifting rollers 4 altogether in two side bayonet slots 8 of track 2 in jib revolution stand 3 upper edges; Jib revolution stand 3 is provided with the propelling oil cylinder 5 that is connected with main frame, advance the tailpiece of the piston rod of oil cylinder 5 to link to each other with mainframe, the cylinder barrel end links to each other with revolution stand 3, when oil cylinder 5 stretches, shifting roller 4 rolls in two side bayonet slots 8 of walking track 2, drives jib revolution stand 3 and moves forward and backward; Be equipped with on the jib revolution stand 3 in two side bayonet slots 8 of walking track 2 that roller scraper plate 6 places shifting roller 4 front and back, be used to remove the dregs on the walking track 2, guarantee to pass through smoothly during roller 4 is in the draw-in groove 8 of walking track 2; Walking track 2 two ends are equipped with the safety catch 1 of band yielding rubber spring 9, the moving range of mechanical constraint revolution stand (3).
As shown in Figure 3, shifting roller 4 is to combine with installation seat plate 7 with the compound roller bearing 10 of standard, and wherein compound roller bearing 10 central axiss are fixedlyed connected with installation seat plate 7, and outstanding little runner 11 is equipped with in compound roller bearing 10 sides.
Shifting roller 4 is fixedlyed connected with jib revolution stand 3 by installation seat plate 7, composite bearing 10 in 4 groups of shifting rollers 4 is positioned in 4 clamp bar slots 8 of two I-shaped tracks 2, leave the 1-2mm gap between little runner 11 that the side is outstanding and the riser in the track 2, behind jib revolution stand 3 sideslips, outstanding little runner 11 contacts with track 2 risers, frictional force is between the two rotated little runner 11, makes stand 3 can continue to move, and prevents stuck.
The utility model has adopted I-shaped 4 tracks to place the horizontal mobile mechanism of shifting roller, efficiently solve the phenomenon of existing travel mechanism and tired spot corrosion easy to wear, realized the purpose of increase spray regime under the situation that does not increase jib length because of the big generation track of contact stress.
