Description

TECHNICAL FIELD

[0001] The present application relates to the production field of injection mechanism, and in particular to an automatic anchoring agent slurry injection mechanism. BACKGROUND

[0002] Coal mine tunneling needs to support the tunnel with anchor rods and anchor cables, and needs to load anchoring agent into the drill hole. At present, there are three installation methods for anchoring agent, namely manual installation, mechanical installation with manual assistance, and pneumatic automatic installation. The manual installation method is relatively flexible, but when the installation position is high, the worker needs to climb high, which reduces the efficiency and has safety hazards; when working at a high place, more than two people often need to cooperate, which requires a large number of personnel; manual installation of cartridges also has corrosion hazards. When the mechanical installation with manual assistance is used, the anchoring agent is loaded into the cylinder, the cylinder is aligned with the drill hole, and the worker on the ground pushes the anchoring agent into the drill hole, which cannot realize automatic and continuous installation. The pneumatic automatic device for anchoring agent has the following shortcomings: (1) The pneumatic installation has strict requirements for air pressure control. Too large air pressure can easily damage the anchoring agent, and too small air pressure cannot reliably push the anchoring agent into the drill hole, and it is difficult to provide very stable air pressure in the underground environment; (2) After the air pressure pushes the anchoring agent into the drill hole, the tail wing installed on the anchoring agent suspends the anchoring agent in the drill hole. The success rate of suspension is greatly affected by air pressure, speed, roughness of the drill hole, and whether there is water in the drill hole; (3) The reliability is not high, but there is no available method to determine whether it is successful, only the installation effect of the anchor rod can be used to determine; (4) The operation equipment has a long idle time between the drill hole and the injection process, and the efficiency is low.

[0003] As can be seen from the above, no matter which installation method is used, the anchoring agent is mostly a finished cartridge, and the finished cartridge is difficult to mix uniformly, which causes waste of medicine and unreliable solidification, and further affects the anchoring effect.

[0031] Embodiment one

[0032] An automatic anchoring agent slurry injection mechanism, comprising a first medicament cylinder 1, a second medicament cylinder 2, an injection cylinder 4, a push rod 5, a power head 6 and a lifting oil cylinder 8.

[0033] The first medicament cylinder 1 and the second medicament cylinder 2 are arranged side by side, and the top ends of the first medicament cylinder 1 and the second medicament cylinder 2 are provided with openings for pouring medicaments into the openings, and the openings are connected with plugs 20. The injection cylinder 4 is arranged between the first medicament cylinder 1 and the second medicament cylinder 2, and the injection cylinder 4 is communicated with the first medicament cylinder 1 and the second medicament cylinder 2 respectively. The bottoms of the first medicament cylinder 1 and the second medicament cylinder 2 are respectively provided with pistons 3, and the pistons 3 can move up and down. The pistons 3 divide the first medicament cylinder 1 and the second medicament cylinder 2 into upper chambers and lower chambers, wherein the upper chambers are used for containing medicaments, and the lower chambers are used for containing high-pressure hydraulic oil. The high-pressure hydraulic oil filled into the lower chambers can make the pistons slide upward to press the medicaments into the injection cylinder 4. The bottoms of the first medicament cylinder 1 and the second medicament cylinder 2 are respectively provided with metering valves 7 for metering the high-pressure oil filled into the first medicament cylinder 1 and the second medicament cylinder 2, so as to control the amount of medicaments pressed into the injection cylinder 4.

[0034] One end of the push rod 5 extends into the injection cylinder 4, and the other end extends out of the injection cylinder 4 and can be fixed with the power head 6. The power head 6 can slide up and down to drive the push rod 5 to slide up and down in the injection cylinder 4. When the push rod 5 slides upward, the medicaments in the injection cylinder 4 can be pressed into the anchor hole. The bottom of the injection cylinder 4 is provided with a spring 11, and the push rod 5 can move downward to make the spring 11 in a compressed state to form a buffer for the push rod 5.

[0035] The lifting oil cylinder 8 is connected to the drilling frame 9 through a plurality of supports 21, and the lifting oil cylinder 8 and the drilling frame 9 are connected with a rotating oil cylinder 10. The first medicament cylinder 1, the second medicament cylinder 2 and the injection cylinder 4 are all connected to the lifting oil cylinder 8 and move up and down under the action of the lifting oil cylinder 8.

[0036] Before the device works, the high-pressure hydraulic oil is emptied, the pistons 3 in the first medicament cylinder 1 and the second medicament cylinder 2 are lowered to the bottom, the plugs 9 of the first medicament cylinder 1 and the second medicament cylinder 2 are opened, and two slurries of anchor agents are respectively injected into the first medicament cylinder 1 and the second medicament cylinder 2.

[0037] After the drilling is completed, the rotating oil cylinder 10 drives the supports 21 to rotate the injection cylinder 4 to the central position to align the drilled hole, and the lifting oil cylinder 8 acts to insert the head of the device injection cylinder 4 into the drilled hole. The power head 6 rises to the bottom of the push rod 5 and fixes the push rod 5 with the clamping jaws thereof. The specific structure of the power head 6 is shown in the drawing, which is a mechanical hand with two joints.

[0038] When the power head 6 moves downward, the push rod 5 is lowered to the bottom, the first medicament cylinder 1 and the second medicament cylinder 2 are communicated with the injection cylinder 4, the metering valve 7 on the first medicament cylinder 1 and the second medicament cylinder 2 is opened, the high-pressure hydraulic oil enters the bottom of the first medicament cylinder 1 and the second medicament cylinder 2, the piston 3 is pushed to rise, the piston 3 rises to extrude the medicament in the upper part, the medicament is pressed into the injection cylinder 4, and the medicament enters the drilled hole along the injection cylinder 4. According to the depth and diameter of the hole, the required amount is calculated, the data is input into the metering valve 7, and when the injection amount reaches the required amount, the metering valve 3 is closed, and the medicament stops being discharged. Subsequently, the power head 6 rises, the push rod 5 slides upward, and the medicament in the injection cylinder 4 is discharged.

[0039] Example two

[0040] The difference between this embodiment and example one is that the injection cylinder 4 in this embodiment is further provided with a stirring impeller 12, a driving rod 14 and a fixer 17.

[0041] The stirring impeller 12 is rotationally connected to the fixer 17. The driving rod 14 passes through the push rod 5 and the stirring impeller 12 in sequence. One end of the driving rod 14 is provided with a spiral groove 15, the stirring impeller 12 is provided with a ball 16, and the ball 16 is placed in the groove 15. Under the action of the ball 16 and the groove 15, the up-and-down movement of the driving rod 14 can make the stirring impeller 12 rotate. The stirring impeller 12 is provided with a spiral duct 13 in the circumferential direction. When the stirring impeller 12 rotates, the medicament in the injection cylinder 4 can be stirred spirally, so that the medicament in the injection cylinder 4 is uniformly mixed.

[0042] The outer wall of the fixer 17 is provided with a guide groove, and the injection cylinder 4 is provided with a guide protrusion. Under the action of the guide groove and the guide protrusion, the fixer 17 can move up and down in the injection cylinder 4. An electromagnetic coil 18 is arranged in the middle and lower part of the injection cylinder 4, and the fixer 17 is provided with a magnetic pole. When the electromagnetic coil 18 is electrified, the fixer 17 and the stirring impeller 12 are fixed to the middle and lower part of the injection cylinder 4.

[0043] In this embodiment, there are two power heads 6, and the two power heads 6 are fixed on different lifting oil cylinders 8 respectively. One of the power heads 6 is used to fix the push rod 5, and the other power head 6 is used to fix the driving rod 14.

[0044] Compared with the first embodiment, the stirring vane 12, the driving rod 14 and the fixer 17 have two functions in this embodiment: (1) to mix the two kinds of medicaments thoroughly; (2) to make the medicaments eject more quickly. Specifically, when the fixer 17 and the stirring vane 12 are fixed, the driving rod 14 moves up and down, and the stirring vane 12 rotates, so that the medicaments are mixed thoroughly. When the push rod 5 moves up, the driving rod 14 is fixed by one of the power heads 6, the power supply of the electromagnetic coil 18 is cut off, and the fixer 17 and the stirring vane 12 are pushed up by the push rod 5 and slide up. At this time, the medicaments in the syringe 4 are ejected at a high speed due to the rotation of the stirring vane 12. Since the medicaments are ejected at a high speed, the effect of adhering to the hole is also good.

[0045] The above description is only the preferred embodiment of the present application, and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
