Description

Technical Field

[0001] The present invention relates to the field of tunnel construction, and in particular to a support material injection device and method based on coordinated utilization of multi-source solid waste. Background Art

[0002] The support material injection device can mix aggregates and concrete in a certain proportion, transport them through pipelines, and spray them at high speed onto the sprayed surface to solidify and harden, thereby forming a concrete support layer. The aggregates are made of multi-source solid waste materials. Multi-source solid waste support aggregates refer to aggregates that use a variety of industrial or construction waste as raw materials and are used in support structures after being processed by specific processes. The application of this material can not only effectively solve the problem of solid waste treatment and reduce damage to the environment, but also reduce engineering costs.

[0003] However, when the existing support material spraying device is used to spray concrete and aggregate, the surrounding rock on the inner wall of the tunnel is uneven, so the surface of the sprayed concrete and aggregate is also uneven, which makes it difficult to smooth the surface of the concrete and aggregate. In addition, part of the aggregate will rebound during the spraying, making the sprayed concrete and aggregate layers not dense enough, and thus making the support effect of the tunnel not good enough. Summary of the invention

[0014] A method for using a support material injection device based on the coordinated utilization of multi-source solid waste includes the following working steps:

[0015] Step 1: The staff starts the hydraulic cylinder, and the telescopic shaft of the hydraulic cylinder drives the mobile ring frame to move upward. The upward movement of the mobile ring frame drives the injection pipe, the push rod, the contact rod, the bending rod and the smoothing roller to move upward. The upward movement of the push rod causes the mobile guide ring to move. The movement of the mobile guide ring drives the two contact rods to move away from each other. The movement of the two contact rods drives the two injection pipes, the two bending rods and the two smoothing rollers to move, so that the injection pipe and the smoothing roller can maintain a suitable distance from the roadway.

[0016] Step 2: The mobile loading machine will mix the aggregate and concrete evenly. The staff will start the delivery pump, which will deliver the aggregate and concrete to the three-way joint through the curved hose. Then the aggregate and concrete will be delivered to the two injection pipes through the connecting hose. Finally, the aggregate and concrete will be sprayed onto the inner wall of the tunnel through the injection pipe to support the inner wall of the tunnel.

[0017] Step 3: The staff starts the driving motor, which drives the rotating gear to rotate through the active gear. The rotating gear drives the swing arm to swing. The upward swing of the swing arm drives the injection pipe and the smoothing roller to swing upward. The upward swing of the smoothing roller will smooth the part of the roadway where the aggregate and concrete have been sprayed, making the uneven aggregate and concrete in the roadway smooth.

[0018] The beneficial effects are as follows: 1. The rotation of the two driving motors will drive a driving gear to rotate through the output shaft respectively, and each driving gear will drive the rotating gear meshing therewith to rotate, so that the two swing arms will swing upward along the movable ring frame, and the upward swing of the swing arm will drive the injection pipe, the bending rod and the smoothing roller to swing upward, and the upward swing of the injection pipe will continue to spray a new part of the tunnel, and the upward swing of the smoothing roller will smooth the part of the tunnel that has been sprayed with aggregate and concrete, so that the uneven aggregate and concrete in the tunnel become smooth, so that the support effect of the tunnel is better.

[0019] 2. The upward swing of the extrusion block will be squeezed by the convex block of the extrusion ring to make the extrusion block move. The movement of the extrusion block will cause the telescopic rod of the piston cylinder connected to the extrusion block to contract. The contraction of the telescopic rod of the piston cylinder will cause the hydraulic oil to be transported to the piston cylinder on the bending rod through the hydraulic pipe, so that the telescopic rod of the piston cylinder on the bending rod is extended. The extension of the telescopic rod of the piston cylinder on the bending rod will push the extrusion frame to move. The movement of the extrusion frame will push the collected aggregate and concrete, so that the aggregate and concrete can be combined with the aggregate and concrete on the roadway, making the aggregate and concrete on the roadway more compact, thereby further improving the support effect of the roadway.

[0020] 3. The movement of the extrusion frame will drive the movement of the mobile frame, and the movement of the mobile frame will move along the through slot of the guide frame to make the mobile frame move left and right. The left and right movement of the mobile frame will push the driven frame and the stirring frame to move left and right. The left and right movement of the mobile frame and the stirring frame will stir the aggregate and concrete collected by the smoothing roller, the extrusion frame and the limit frame, which can avoid the accumulation of aggregate and concrete, and make the aggregate and concrete evenly combined with the aggregate and concrete on the roadway, so that the support effect of the roadway is better.

[0037] The smoothing mechanism includes a bent rod 66 and a smoothing roller 67 . A bent rod 66 is welded to each movable plate 63 , and a smoothing roller 67 is rotatably connected to each bent rod 66 .

[0038] At first, the staff will adjust the distance between the injection pipe 45 and the smoothing roller 67 and the inner wall of the tunnel according to the size of the tunnel. The staff will first start the hydraulic cylinder 3, and the telescopic shaft of the hydraulic cylinder 3 will drive the mobile ring frame 31 to move upward. The upward movement of the mobile ring frame 31 will drive the mounting plate 32, the driving motor 33, the rotating gear 34, the driving gear 35, the swing rod 42, the three-way joint 44, the injection pipe 45, the connecting hose 46, the push rod 62, the moving plate 63, the tension spring 64, the contact rod 65, the bending rod 66 and the smoothing roller 67 to move upward, and the three-way joint 44 moves upward.

At the same time, the drive motor 33 will rotate intermittently, and when the injection pipe 45 sprays the aggregate and concrete into the tunnel with the smoothing roller 67, the two drive motors 33 rotate, and the rotation directions of the two drive motors 33 are different. The rotation of the two drive motors 33 will drive a driving gear 35 to rotate through the output shaft, and each driving gear 35 will drive the rotating gear 34 meshing therewith to rotate. The rotation of the rotating gear 34 will respectively drive one swing rod 42 to rotate forward and the other swing rod 42 to rotate reversely, so that The two swinging rods 42 swing upward along the moving ring frame 31, and the swinging rod 42 swings upward to drive the spraying pipe 45, the moving plate 63, the tension spring 64, the contact rod 65, the bending rod 66 and the smoothing roller 67 to swing upward, and the spraying pipe 45 swings upward to bend the connecting hose 46. After the spraying pipe 45 and the smoothing roller 67 swing upward a certain distance, the two driving motors 33 stop rotating, and the spraying pipe 45 swings upward to continue spraying a new part of the roadway, and the smoothing roller 67 swings upward to spray the existing part of the roadway. After the aggregate and concrete are sprayed, the part is smoothed, so that the uneven aggregate and concrete of the roadway become smooth, so that the supporting effect of the roadway is better.

[0039] Embodiment 2: Based on embodiment 1, Figure 6-Figure 7 As shown, it also includes a transmission mechanism, which includes an extrusion ring 71, a connecting frame 72, a piston cylinder 73, an extrusion block 74 and a hydraulic pipe 75. The extrusion ring 71 is welded on the movable ring frame 31, and a plurality of protrusions are provided on the extrusion ring 71. A connecting frame 72 is welded on each swing rod 42, and a piston cylinder 73 is fixedly connected to each connecting frame 72. Each bending rod 66 is fixedly connected to a piston cylinder 73. The two piston cylinders 73 on the same side form a group. In each group, a extrusion block 74 is fixedly connected to the telescopic rod of the piston cylinder 73 close to the extrusion ring 71.

A limiting frame 77 is welded on each bent rod 66, and each limiting frame 77 is slidably connected to the extrusion frame 76. A return spring 78 is connected between each extrusion frame 76 and each bent rod 66.

[0041] At first, the two bent rods 66 move away from each other, which will drive the piston cylinder 73 fixed on the bent rod 66 to move. The movement of the piston cylinder 73 fixed on the bent rod 66 causes the hydraulic pipe 75 to move. The injection pipe 45 sprays aggregate and concrete onto the roadway, and some of the aggregate and concrete will rebound. The smoothing roller 67, the extrusion frame 76 and the limit frame 77 will collect the partially rebounded aggregate and concrete. The swinging rod 42, the bent rod 66 and the smoothing roller 67 will swing upward, which will drive the connecting frame 72, the piston cylinder 73, the extrusion block 74, the hydraulic pipe 75, the extrusion frame 76, the limit frame 77 and the return spring 78 to swing upward. The upward swinging of the extrusion block 74 will be squeezed by the convex block of the extrusion ring 71, causing the extrusion block 74 to move. The movement of the extrusion block 74 will cause the telescopic rod of the piston cylinder 73 connected to the extrusion block 74 to contract, and the extension and contraction of the piston cylinder 73 will cause the extension and contraction of the piston cylinder 73. The contraction of the retracting rod will cause the hydraulic oil to be transported to the piston cylinder 73 on the bent rod 66 through the hydraulic pipe 75, causing the telescopic rod of the piston cylinder 73 on the bent rod 66 to extend. The extension of the telescopic rod of the piston cylinder 73 on the bent rod 66 will push the extrusion frame 76 to move. The movement of the extrusion frame 76 causes the reset spring 78 to stretch. The movement of the extrusion frame 76 will push the collected aggregate and concrete, so that the aggregate and concrete can be combined with the aggregate and concrete on the roadway, making the aggregate and concrete on the roadway more compact, thereby further improving the support effect of the roadway. The extrusion block 74 continues to swing upward, causing the extrusion block 74 to disengage from the extrusion ring 71, and the reset spring 78 will drive the extrusion frame 76 to reset. The reset of the extrusion frame 76 will drive the piston cylinder 73 and the extrusion block 74 to reset. The smoothing roller 67 continues to swing upward to press and smooth the aggregate and concrete.

[0042] Embodiment 3: Based on embodiment 2, Figure 7-10 As shown, a toggle mechanism is also included, which includes a guide frame 81, a movable frame 82, a driven frame 83 and a stirring frame 84.

A stirring frame 84 is welded to each group of driven frames 83, and each stirring frame 84 contacts a smoothing roller 67.

[0043] The movement of the extrusion frame 76 will drive the movement of the mobile frame 82, and the movement of the mobile frame 82 will move along the through groove of the guide frame 81 so that the mobile frame 82 moves left and right. The left and right movement of the mobile frame 82 will push the driven frame 83 and the stirring frame 84 to move left and right. The left and right movement of the mobile frame 82 and the stirring frame 84 will stir the aggregate and concrete collected by the smoothing roller 67, the extrusion frame 76 and the limiting frame 77, which can avoid the accumulation of aggregate and concrete, and make the aggregate and concrete evenly combined with the aggregate and concrete on the roadway, so as to achieve better support effect on the roadway. The resetting of the extrusion frame 76 will drive the mobile frame 82, the driven frame 83 and the stirring frame 84 to reset.

[0044] Embodiment 4: Based on the embodiment 3, Figure 1 As shown, a guide nozzle 9 is also included, and a guide nozzle 9 is welded to each injection pipe 45.

[0045] The aggregate and concrete in the injection pipe 45 will be guided by the guide nozzle 9 when being ejected, so that the ejected aggregate and concrete will deviate to the direction of the smoothing roller 67, so that most of the aggregate and concrete will rebound in the direction of the smoothing roller 67, so that the smoothing roller 67, the extrusion frame 76 and the limit frame 77 can collect more aggregate and concrete, so that more aggregate can be combined with the aggregate and concrete on the roadway, making the aggregate and concrete on the roadway more compact.

6. The method for using the support material injection device based on the coordinated utilization of multi-source solid waste according to claim 5 is characterized in that: The following steps are included: Step 1: The staff starts the hydraulic cylinder (3), and the telescopic shaft of the hydraulic cylinder (3) drives the movable ring frame (31) to move upward. The upward movement of the movable ring frame (31) drives the injection pipe (45), the push rod (62), the contact rod (65), the bending rod (66) and the smoothing roller (67) to move upward. The upward movement of the push rod (62) causes the movable guide ring (61) to move. The movement of the movable guide ring (61) drives the two contact rods (65) to move in a direction away from each other. The movement of the two contact rods (65) drives the two injection pipes (45), the two bending rods (66) and the two smoothing rollers (67) to move, so that the injection pipe (45) and the smoothing roller (67) can maintain a suitable distance from the roadway. Step 2: The mobile loader (1) will evenly mix the aggregate and concrete, and the staff will start the delivery pump (2). The delivery pump (2) will deliver the aggregate and concrete to the three-way joint (44) through the curved hose (47), and then the aggregate and concrete will be delivered to the two injection pipes (45) through the connecting hose (46). Finally, the aggregate and concrete will be injected onto the inner wall of the roadway through the injection pipe (45) to support the inner wall of the roadway; Step 3: The staff starts the driving motor (33), and the driving motor (33) drives the rotating gear (34) to rotate through the driving gear (35). The rotating gear (34) drives the swinging rod (42) to swing. The swinging rod (42) swings upward, which drives the spraying pipe (45) and the smoothing roller (67) to swing upward. The smoothing roller (67) swings upward to smooth the part of the roadway where the aggregate and concrete have been sprayed, so that the uneven aggregate and concrete in the roadway become flat.
