Description

TECHNICAL FIELD

[0001] The present application relates to the field of colloidal material grouting conveying pump, in particular to a colloidal material conveying pump for grouting. BACKGROUND

[0002] In the process of underground tunnel construction, anchor rod reinforcement and anchoring surrounding rock mass are often used. When the construction section has abundant underground water, large underground water often accompanies, at this time, the anchor rod hole needs to be blocked, and in the process of blocking, the concentrated slurry is filled in the gap between the anchor rod and the anchor rod hole by using the grouting pump, so as to achieve the effect of rapid blocking.

[0003] Because the concentrated slurry has the ability of coagulation, strong adhesion, high viscosity and high cohesion with each other. High concentration and low water content are its prominent features, and the whole is in the state of non-newtonian fluid. Therefore, ordinary grouting pump cannot pump, and special pump needs to be used for conveying. Secondly, to meet the anchor rod hole not only has downward drilling, also has horizontal drilling and upward drilling to the top position, has enough resistance to downward gravity viscous resistance. The same is true for the shield machine shield body mud effect grouting, the mud effect material viscosity reaches the plastic state of soil.

[0004] The existing grouting pump is often divided into two categories, one is a screw pump which uses the rotation of the screw to discharge the liquid, the pump shaft is driven to rotate by the motor, so as to drive the screw to rotate around its axis, at the same time, the screw rolls along the inner surface of the bushing. When the screw rotates one turn, the liquid in the sealing cavity of the pump is pushed forward by one pitch, and after continuous movement, the liquid is pumped out. However, for non-newtonian fluid, the outlet pressure of this type of pump does not exceed 1MPa, and the hole anchor rod inner diameter is 10-12mm, the length is 3-4m, the distance from the grouting pump to the anchor rod inlet is provided with 10-20m high pressure steel wire rubber pipe, and the pump outlet pressure cannot be lower than 10MPa, so this type of screw pump cannot transport concentrated slurry.

[0005] The second type of pump is a plunger pump, and the plunger pump can be divided into ball valve type distribution valve and S valve type pipe valve type distribution valve according to the distribution valve. The ball valve type distribution valve changes the volume on both sides of the hopper by the movement of the piston in the hopper, so that the liquid pressure in the hopper is reduced, the suction ball valve is opened under the action of gravity, the liquid is discharged, the suction ball valve is closed, the liquid to be transported enters the cavity under the action of pressure difference. When the piston moves to the left later, the liquid is extruded, the liquid pressure in the cavity increases sharply, the suction ball valve is closed under the action of this pressure, and the discharge ball valve is closed, the liquid in the cavity is discharged to the discharge pipeline under the action of pressure difference. Cycle repeatedly, the pump continuously sucks and discharges liquid.

[0006] However, the flow channel structure inside the suction ball valve and the discharge ball valve is very complex, so that the medium will be divided, turned, diverted and other movements in the ball valve. Once the viscosity of the medium reaches a certain degree, the medium will lack fluidity and become paste-like. Due to the complex structure of the flow channel, the colloid will remain on the surface of the passing ball valve and flow channel, causing the suction ball valve and the discharge ball valve to fail to open normally or close in time, resulting in pumping failure.

[0007] As for the S valve type pipe valve type distribution valve, the pumping mechanism is composed of two main oil cylinders, a water tank, a reversing mechanism, two mud cylinders, two pistons, a hopper, a distribution valve (S pipe), a swing arm, two swing oil cylinders and a discharge port.

[0008] When pumping the mud, under the action of the main oil cylinder, the left piston advances and the right piston retreats. At the same time, under the action of the swing oil cylinder, the distribution valve S pipe is communicated with the left mud cylinder, and the right mud cylinder is communicated with the hopper. In this way, the right piston retreats to suck the mud in the hopper into the mud cylinder, and the left piston advances to pump the mud in the left mud cylinder into the distribution valve S pipe.

[0009] When the right piston retreats to the end of the stroke, the reversing device in the water tank is triggered, the main oil cylinder changes direction, and the swing oil cylinder changes direction, so that the distribution valve S pipe is communicated with the right mud cylinder, and the left mud cylinder is communicated with the hopper. At this time, the left piston retreats and the right piston advances, and the cycle is repeated, so as to realize continuous pumping.

[0010] When the water content of the medium is required to be lower and lower, and the concentration of the medium increases to a certain degree, the medium lacks fluidity and becomes paste-like. At this time, when the piston in the material cylinder retreats and the volume increases, it is difficult for the vacuum to flow the paste in the pump hopper into the mud cylinder in a whole air-tight manner. Therefore, in order to improve the pumping efficiency of such medium, a forced feeding device is arranged above the hopper, as shown in the accompanying drawings Figure 1 The pump hopper has a closed or semi-closed pipeline, a power-driven screw shaft and screw blades, which constitute a forced feeding device. The screw applies external force to help force the paste into the pump hopper and the mud cylinder.

[0011] However, when conveying the coagulation and colloid medium, the flow channel from the feeder to the distribution valve is too long, and the surface of the passing structure is relatively complex, so it is difficult to clean the screw blades inside and the inner and outer surfaces of the S pipe distribution valve.

[0012] Because of the adhesive and solidification characteristics of the medium, any object in contact with the medium will be adhered and solidified, so it must be cleaned quickly. For example, when using a mixed medium with cement and water glass components, the water content is less than 25%, and the material will adhere to all the inner walls of the passing container, forming a scale-like residue. After each use, washing with normal pressure water is ineffective, and high pressure water must be used to spray the area to clean the residue. Once solidified, cleaning the pump hopper will be a time-consuming and labor-intensive additional task, which is very tedious.

[0013] Secondly, because the medium has very poor fluidity, the feeding device can force the medium into the pumping cylinder by applying pressure to the medium. The pressure screw shaft and blade of the feeding machine and the S-shaped distribution valve for switching the material suction and discharge during the pumping process are immersed in the medium. These moving parts are in direct contact with the medium, and the sealing and lubrication of the contact surface need to be ensured. Practical new type content

[0072] The middle part of the connecting end 1213 is curved away from the material cylinder 130, and the first end 1211 and the second end 1212 are located on the side close to the material cylinder 130;

[0073] The driving mechanism 140 is rotated to drive the first end 1211 or the S pipe 122 to communicate with the communication port 130a, so that the hopper 110 fills the material cylinder 130 or pushes the material cylinder 130 to the S pipe 122 through the communication pipe 121.

[0074] Please refer to Figures 1-6In the embodiment, the driving mechanism 140 drives the communicating piece 120 to rotate clockwise, so that the first end 1211 is aligned with the communicating port 130a of the cylinder 130, and the second end 1212 is aligned with the hopper 110.

[0075] The gelatinous material in the hopper 110 enters the cylinder 130 through the communicating pipe 121.

[0076] The piston of the cylinder 130 retreats, and the medium is sucked under the action of negative pressure.

[0077] The driving mechanism 140 rotates the communicating piece 120 counterclockwise, so that the S pipe 122 is connected with the communicating port 130a of the cylinder 130.

[0078] The piston of the cylinder 130 advances, and the medium is pushed into the S pipe 122 and discharged through the discharge pipe 160.

[0079] The driving mechanism 140 continuously switches the connection state of the communicating piece 120, and the cylinder 130 continuously sucks and discharges the medium, so that the medium is continuously transported.

[0080] Because the medium path is simplified and dead angles are not easily generated, the device is more convenient to clean, and the maintenance cost after operation is reduced.

[0081] Because the flow passage of the communicating pipe 121 is simple, the cleaning is more convenient.

[0082] It should be noted that the communicating pipe 121 is approximately a "C" type or "U" type pipe.

[0083] The S pipe 122 is a bent pipe with two open ends, which is connected by two sections of the bent pipe with opposite bending directions and center symmetry.

[0084] The cylinder 130 has a piston, an oil cylinder and a cylinder body inside, the oil cylinder drives the piston to move in the cylinder body to suck or discharge the medium in the cylinder body.

[0085] In at least one embodiment of the present application, the first end 1211 and the second end 1212 are arranged in parallel.

[0086] Please refer to Figures 1-6 In the embodiment, the first end 1211 and the second end 1212 are arranged in parallel, so that the first end 1211 and the second end 1212 are located on the same plane, the shape of the communicating pipe 121 is approximately "C", and the structure of the communicating pipe 121 is more simple, so that the communicating pipe 121 is convenient to clean.

[0088] Please refer to Figures 1-6 In this embodiment, the first inlet 1211a is used to communicate with the cylinder 130, and ensures that the gel material in the hopper 110 can smoothly enter the cylinder 130 through the communication pipe 121.

[0089] The second inlet 1212a is used to communicate with the hopper 110, so that the hopper 110 becomes a stable medium supply source.

[0090] The first inlet 1211a and the second inlet 1212a are provided in the same direction, which ensures the consistency of the flow direction of the medium in the filling and discharging stages, and avoids fluid turbulence or stagnation caused by direction differences.

[0091] Reduces adhesion and blockage of high-viscosity medium caused by complex flow path.

[0092] The gel material has the characteristics of high viscosity and easy adhesion, and the consistent direction of the inlet design reduces the complex turning in the fluid path, making the transportation of high-viscosity medium more efficient.

[0093] Especially when transporting high-viscosity and easily solidified gel medium, by simplifying the flow path, reducing resistance and improving cleanliness, the problems of low efficiency and difficult maintenance in the prior art are solved, which has significant technical progress and practical value.

[0099] Please refer to Figures 1-6 In this embodiment, the transmission part transmits the rotating power of the driving mechanism 140 to the communication member 120 through the meshing action with the engagement part, so that the communication member 120 rotates stably.

[0100] The mechanical engagement ensures the accuracy of power transmission, avoiding low transmission efficiency or rotation failure of the connecting member 120 caused by sliding or looseness.

[0101] The driving motor 141 is started after being powered on, and its output end provides initial rotating power at a certain rotating speed.

[0102] The output end of the driving motor 141 is engaged with the speed reduction gear set, which adjusts the rotating speed and torque of the output, converting high-speed rotation into low-speed high-torque output suitable for driving the connecting member 120.

[0103] The transmission part of the speed reduction gear set is engaged with the engagement part of the connecting member 120, realizing power transmission through mechanical linkage.

[0104] The connecting member 120 rotates under the driving of the driving mechanism 140, aligning the first end 1211 with the filling port 130a of the material cylinder 130 for filling, or aligning the S-shaped pipe 122 with the filling port 130a of the material cylinder 130 for discharging.

[0105] The continuous rotation of the driving motor 141 makes the connecting member 120 rotate smoothly in the set direction and speed.

[0106] The connecting member 120 alternately switches between the filling and discharging states, completing the continuous conveying of the medium.

[0107] The cooperation of the engagement part and the transmission part ensures the reliability and accuracy of power transmission between the driving mechanism 140 and the connecting member 120.

[0116] The baffle 150 effectively isolates the cylinder 130 from the remaining mechanical components, thereby stabilizing the structure and reducing vibration.

[0117] The baffle 150 has two shielding positions, namely a first shielding position and a second shielding position.

[0118] When the driving mechanism 140 drives the communication member 120 to rotate so that the communication pipe 121 is in communication with the connecting port of the cylinder 130, the second end 1212 is in communication with the discharge pipe 160, and the S pipe 122 moves to the first shielding position to shield the S pipe 122, the piston in the cylinder 130 moves backward (away from the communication pipe 121), the hopper 110 injects medium into the second end 1212 through the discharge pipe 160, and the medium enters the cylinder 130 through the communication pipe 121.

[0119] After the injection of the medium is completed, the driving mechanism 140 rotates to drive the communication member 120 to rotate in the opposite direction, so that the communication pipe 121 rotates to the second shielding position, at this time, the S pipe 122 is aligned with the connecting port of the cylinder 130, the piston in the cylinder 130 moves toward the S pipe 122 to push the medium in the cylinder 130 into the S pipe 122, and the medium is discharged through the S pipe 122 to complete the pushing of the material.

[0120] The above steps are repeated to complete continuous pushing and feeding of the material, the first shielding position is used to shield the S pipe 122 to prevent the medium in the S pipe 122 from leaking out, and the second shielding position is used to shield the communication pipe 121 to prevent the medium in the communication pipe 121 from leaking out.

[0124] In at least one embodiment of the present application, the cylinder 130 is two;

[0125] The two communication pipes 121 are respectively arranged on the two sides of the S pipe 122.

[0126] Please refer to Figures 1-8 In the embodiment, the two communication pipes 121 are respectively arranged on the two sides of the S pipe 122. In use, the driving mechanism 140 drives the communication piece 120 to rotate, so that the first end 1211 of one of the communication pipes 121 is aligned with one of the material cylinders 130 for filling, and the other communication pipe 121 is in a shielding state, while the S pipe 122 is communicated with the other material cylinder 130 for discharging. After completion, the driving mechanism 140 reversely rotates to drive the communication piece 120 to rotate, so that the S pipe 122 rotates to the material cylinder 130 after filling for discharging. The communication pipe 121 in the shielding state rotates to the material cylinder 130 after discharging for filling, so as to realize uninterrupted filling and discharging, thereby improving the efficiency of medium conveying.
