Abstract
The utility model provides an automatic spraying and forming device for the mine tunnel concrete supporting. The utility model is composed of a walking small vehicle, a film plate, a liquid pressing cylinder, a liquid pressing pump station system, a film plate supporting, a swinging arm and a spraying pipe. The liquid pressing cylinder controls the film plate to reach to required tunnel cross section shape, and the walking small vehicle drives the film plate to move forward. The swinging arm drives the spraying pipe to swing to make the spraying pipe move back and forth between the surrounding rock of the tunnel and the film plate and spray concrete with the accelerating agent. A controlling valve unit controls the forward movement of the small vehicle and the swinging speed of the swinging arm. The utility model has the advantages of zero concrete spraying rebound degree, smooth and tidy tunnel cross section, good under stressing condition, convenient operation, high speed, high safety and low labor intensity.
Description
The utility model relates to the automatic injection molding device of a kind of mine laneway concrete support.
Following two kinds of modes are adopted in existing mine laneway concrete support construction: the one, adopt atypic manually-operated spraying operation, exist concrete springback rate height, roadway shape irregularity, spray-up gage distortion, cause that the tunnel is stressed irregular and roadway deformation takes place, so that destroy; Another kind is to adopt manually to set up template, artificial pail fluid concrete, though can obtain more regular drift section shape, but because of operational difficulty, speed of application is slow, and because of the pail fluid concrete can not the stowboard country rock the slit, make roadway surrounding rock self intensity not to be improved, influence the stability of roadway surrounding rock.
The purpose of this utility model is to provide a kind of novel mine laneway concrete support automatic injection molding device, and making concrete springback power is zero, and roadway shape is regular, stressed evenly, realizes spraying operation mechanization.
The purpose of this utility model realizes in the following manner: it comprise template, walking dolly and be installed on hydraulic power unit system on the walking dolly, template supports and concrete sprays rocking arm; Template supports two ends and connects template and walking dolly respectively, and concrete sprays rocking arm one end and is installed on the hydraulic motor axle, and the other end is contained in the gathering sill of template end.Template can be made up of upper and lower template, and cope match-plate pattern is by two hinged forming, and lower bolster and cope match-plate pattern connection place have seam; Template support can by be installed in the guide peg on the template, fairlead and the hydraulic cylinder that is fixed on the walking dolly formed, the position of template is by the template support and control, it can be by a dish that is installed on the hydraulic motor axle that concrete sprays rocking arm, with connecting rod and the rectangle sliding sleeve, the rectangle slide bar that connect of dish and be installed on rolling cover, playpipe composition on the rectangle slide bar, a connecting rod and a dish connection place can be provided with the installing hole more than two or two, to adapt to the needs of regulating rocking arm length.
The utility model is because the upper and lower of jeting area by roadway surrounding rock and template sealing, is zero so concrete sprays rebound degree; The drift section size is controlled by template, and is smooth regular, and stress condition is good; Adopt hydraulic valve bank control construction, easy to operate, labour intensity is low, security intensity height, walking dolly drive template and rocking arm drive playpipe moves simultaneously, and speed of application is fast, the automaticity height is changed the spray-up that template just can obtain various drift section sizes and different-thickness, wide accommodation.
Accompanying drawing has provided an embodiment of the present utility model.
Fig. 1 is a front view of the present utility model;
Fig. 2 is an A-A sectional view of the present utility model;
Fig. 3 is a B-B sectional view of the present utility model;
Fig. 4 is a hydraulic system principle figure of the present utility model.
With reference to the accompanying drawings the utility model is described in further detail.
With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, the utility model is made up of walking dolly (1), lower bolster (3), cope match-plate pattern (4), hydraulic cylinder (5) and (11), rocking arm (6), hydraulic power unit system (7) and control valve group (23), template direction bar (9) and (15), fairlead (10) and (21), playpipe (17) etc.Hydraulic power unit system (7), control valve group (23), template direction cover (10) and (21) all are fixed on the walking dolly (1).Moving forward and backward by hydraulic motor (24) of walking dolly (1) drives, and can carry out stepless speed regulation by control valve group (23).Lower bolster guide peg (9) is fixed on the lower bolster (3), lower bolster (3) is by hydraulic cylinder (11) control position, two cope match-plate patterns (4) are hinged together by hinge ear (13) and hinge (14), and guide peg (15) is affixed with hinge (14), by hydraulic cylinder (5) control position.Cope match-plate pattern (4) has seam with the contact position of lower bolster (3), forms smooth regular cross section, tunnel so that fit tightly.Rocking arm (6) is by the outer dress of rectangle slide bar (18).Rectangle sliding sleeve (19), the cover (16) that rolls, a dish (22) are formed.The mandrel that overlaps (16) that rolls is fixed on the rectangle slide bar (18), the dish (22) be fixed on hydraulic motor (24) the axle on, use screw and connecting rod (20) to connect simultaneously, connecting rod (20) and rectangle sliding sleeve (19) welding, playpipe (17) is fixed on the termination of rectangle slide bar (18).Form the gathering sill that (16) are overlapped in rolling by the curved bar (12) and the rail bar (2) that are fixed on template (3) and the template (4), with the axial location of control rectangle slide bar (18).By the positive and negative running of control valve group (23) control hydraulic motor (24), drive rocking arm (6) reciprocating swing, its swing speed carries out stepless speed regulation by control valve group (23).Prop up the junction of dish (22) and rectangle sliding sleeve (19), be drilled with the screw mounting hole more than two, the requirement of rocking arm change in length when changing to adapt to drift section.When needing work, hydraulic cylinder (5) stretches out, make cope match-plate pattern (4) be raised to the precalculated position, stretch out hydraulic cylinder (11) again, the lower bolster (3) and the seam of cope match-plate pattern (4) are fitted, then, drive walking dolly (1) and rocking arm (6) simultaneously by hydraulic power unit system (7), playpipe (17) begins to spray the concrete (8) that is added with accelerating admixture, and speed that walking dolly (1) drive template (3), (4) move ahead and rocking arm (6) drive the speed of playpipe (17) swing by control valve group (23) stepless speed regulation.Change template and can adapt to various drift section sizes and various jetting thickness.When needs were transported, playpipe (17) was removed in walking dolly (1) and rocking arm (6) stop motion, withdrawal hydraulic cylinder (11), withdraw hydraulic cylinder (5) and then drive walking dolly (1) walking by hydraulic power unit system (7) again.
