Abstract
The utility model discloses a slideable guide beam frame for an air drill. The slideable guide beam frame comprises a base; an upper guide rail group and a lower guide rail group are arranged in parallel on the base; upper sliding seats are freely sleeved on the two ends of the upper guide rail group in a sliding manner; lower sliding seats are freely sleeved on the two ends of the lower guide rail group in a sliding manner; and the base, the upper sliding seats and the lower sliding seats are respectively provided with a lifting table capable of lifting vertically. According to the utility model, due to the sliding design of the upper and lower sliding seats and the lifting tables, a propelling beam and a rock drill mounted thereon can move up and down and left and right, and the problem that the rock drill on a fixed guide beam frame cannot be adjusted and thus cannot completely adapt to the requirement on the position change of blast holes with different radius circles on a tunnel surface is solved; meanwhile, the positions forbidding tapping such as crack and back break in a tunnel are avoided, and the batch drilling construction technology on any position of the tunnel full section is realized; and the guide beam frame adopts a mode of right-angle coordinates and hydraulic oil cylinder drive, and the operation is visual and clear.
Description
Technical field
The utility model belongs to the tunnel excavation equipment technical field, particularly relates to a kind of slidably nose girder frame of the air drill equipment of boring in batches that is used for.
Background technology
When using the air drill equipment to bore shot hole in batches in the tunnel; Before use fixed nose girder frame the time; The relative position of hammer drill is fixing can't be adjusted, and this can't satisfy the status requirement of the different ring layer shot holes in tunnel, works as one of them hammer drill simultaneously and runs into the crack; Owe to dig etc. can't bore position the time, can't avoid.Therefore, a kind of nose girder that can adjust each hammer drill position separately of design has been put up those skilled in the art's problem demanding prompt solution.
The utility model content
The purpose of the utility model is exactly to above-mentioned prior art problems, and a kind of slidably nose girder frame that is used for air drill that can adjust each hammer drill position separately is provided.
The purpose of the utility model realizes through following technical proposals:
A kind of slidably nose girder frame that is used for air drill; Comprise pedestal; The upper rail group that laterally arranges on the pedestal and lower guideway group; Upper rail group two ends are free to slide and are set with upper saddle, and lower guideway group two ends are free to slide and are set with lower slider, but are equipped with the elevating stage of vertical lift on the pedestal, upper saddle, lower slider.
As preferably, said upper saddle, lower slider all are connected with pedestal through telescopic oil cylinder, and under the effect of telescopic oil cylinder, slide along upper rail group, lower guideway group separately.
As preferably, said elevating stage is connected with pedestal, upper saddle, lower slider respectively through the axis of guide, and under the effect of hoist cylinder, slides up and down along the axis of guide separately.
The beneficial effect of the utility model is: the slide design of upper and lower slide and elevating stage; Make forward beam mounted thereto and hammer drill to move up and down; Solved that hammer drill on the fixed nose girder frame can not be adjusted and the requirement that can't adapt to different radii circle shot hole change in location on the tunnel face fully; Can avoid simultaneously because of tunnel internal fissure, out break etc. can not position of opening; Realize full section optional position, tunnel mass drill construction technique, the mode that the nose girder frame adopts rectangular co-ordinate, hydraulic jack to drive, operation is directly perceived simple.
Description of drawings
Fig. 1 is the perspective view of the utility model;
Fig. 2 is the front structure sketch map of the utility model;
Fig. 3 is the perspective view that forward beam is housed.
The specific embodiment
Below in conjunction with specific embodiment and accompanying drawing the utility model is further described.
As depicted in figs. 1 and 2, a kind of slidably nose girder frame that is used for air drill comprises pedestal 1; Upper rail group that laterally arranges on the pedestal 12 and lower guideway group 3; Upper rail group 2 two ends are free to slide and are set with upper saddle 4, and lower guideway group 3 two ends are free to slide and are set with lower slider 5, but are equipped with the elevating stage 6 of vertical lift on the pedestal 1, upper saddle 4, lower slider 5; There are three elevating stages 6 on the upper strata, and there are two elevating stages 6 in lower floor.
Said upper saddle 4, lower slider 5 all are connected with pedestal 1 through telescopic oil cylinder 7, and under the effect of telescopic oil cylinder 7, slide along upper rail group 2, lower guideway group 3 separately.
Described five elevating stages 6 are connected with pedestal 1, upper saddle 4, lower slider 5 through the axis of guide 8 respectively separately, and under the effect of hoist cylinder 9, slide up and down along the axis of guide 8 separately.
As shown in Figure 3, when real work, during such as brill outmost turns shot hole; Need to increase explosion circle radius R 1, R2; Hoist cylinder 9 in the middle of then shrinking makes the elevating stage 6 in the middle of the upper strata move downward, and extends the hoist cylinder 9 of both sides, upper strata simultaneously, makes the elevating stage 6 of both sides, upper strata move upward; Then the camber line of three of the upper strata hammer drill boring point formations becomes straight gradually, and then R1 increases.Shrink two hoist cylinders 9 of lower floor, make the elevating stage 6 of lower floor move upward, R2 increases.Otherwise R1, R2 reduce.When needs reduce spacing L1, L2, the L3 between the hammer drill, then shrink bilevel telescopic oil cylinder 7, the forward beam that is installed on the elevating stage 6 inwardly shrinks with upper and lower slide 4,5, and L1, L2, L3 reduce, on the contrary L1, L2, L3 increase.
After the explosion circle by reality locates; When running into one of them bore position just in the crack or owe to dig when district; Need not to move whole nose girder frame, only need its place hammer drill can be holed together with the position that forward beam is removed in the specification error scope of next door up and down in batches.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
