Description

TECHNICAL FIELD

[0001] The application relates to the technical field of grouting machines, in particular to a basalt grouting machine. BACKGROUND

[0002] At present, in the fields of geological engineering, tunnel construction, mine repair and foundation reinforcement, grouting technology is widely applied as an effective foundation treatment and reinforcement method.

[0003] The basalt grouting liquid contains many mineral components, has a complex molecular structure and strong interaction between the components, and thus has high viscosity. The basalt grouting liquid is a bicomponent paste-like black and white liquid, and after a\b mixing, the liquid is cured by reaction, and the final setting time is 3-5 minutes. This feature enables the grouting liquid to have enough time to diffuse to the leakage channel and compensate for the slow curing defect of polyurethane and single-component polyurea grouting liquid, and in actual application, the basalt grouting liquid can quickly solidify and block the leakage to achieve efficient waterproof and leakage blocking. The various mineral components in the basalt grouting liquid are prone to sedimentation due to density difference in the static state.

[0004] The traditional grouting machine cannot guarantee the uniformity of grouting and has the defect of being unable to guarantee the grouting quality when grouting the basalt grouting liquid due to the high viscosity and easy sedimentation characteristics of the basalt grouting liquid. CONTENT OF THE INVENTION

[0005] In order to adapt to the high viscosity characteristics of the basalt grouting liquid and guarantee the grouting quality when using the basalt grouting liquid, the application provides a basalt grouting machine.

[0006] The basalt grouting machine provided by the application adopts the following technical scheme:

[0007] A basalt grouting machine, comprising a rack, a storage tank, a control system and a grouting pump for providing pressure arranged on the rack, the control system being used for controlling the start and stop of the grouting pump, a grouting port being arranged on the rack, a stirring assembly being arranged in the storage tank, the stirring assembly comprising a vertical rod, a motor and a stirring rod, an opening cover being arranged on the top of the storage tank, the motor being fixed on the opening cover, the output end of the motor being fixedly connected with the top end of the vertical rod through the opening cover, the stirring rod being fixed at one end on the vertical rod and being cantilevered in the direction away from the vertical rod at the other end; and the grouting pump is a high-pressure plunger pump.

[0008] By adopting the technical scheme, the high-pressure plunger pump realizes oil suction and oil compression by reciprocating movement of the plunger in the cylinder to change the volume of the sealed working cavity. When delivering high-viscosity basalt grouting liquid, the reciprocating movement can generate stable and high pressure. Compared with other types of pumps, such stable high pressure can overcome the high viscosity resistance of the grouting liquid and continuously push it out. The gear pump is susceptible to the gap between the teeth when delivering high-viscosity liquid, resulting in large flow fluctuation and low delivery efficiency, while the high-pressure plunger pump can work stably to ensure continuous and efficient grouting process. The high-pressure plunger pump used in the grouting pump can adapt to the high-viscosity characteristics of the basalt grouting liquid. The starting motor drives the vertical rod and the stirring rod to rotate, which can stir the grouting liquid in the storage tank. The basalt grouting liquid contains multiple components. Even if it is a single-component a or b grouting liquid, the mineral particles and other components in it may precipitate in a static state, affecting the uniformity and stability of the grouting liquid. The setting of the stirring assembly can ensure the uniformity of the components of the grouting liquid when it converges, and ensure the uniform mixing of the a and b liquids, so as to adapt to the high-viscosity characteristics of the basalt grouting liquid and ensure the grouting quality when using the basalt grouting liquid.

[0010] By adopting the technical scheme, the two grouting outlet pipes finally converge at the static mixer to realize the mixing of the grouting liquid in the two storage tanks, and the setting of the static mixer ensures the sufficient mixing of the grouting liquid in the two storage tanks.

[0011] Optionally, a pressure gauge and a flow sensor are arranged at the grouting port.

[0012] By adopting the technical scheme, the pressure gauge monitors the grouting pressure, the flow sensor monitors the grouting flow rate, and the control system is matched to make the grouting pressure of the device more stable and improve the grouting quality.

[0014] By adopting the technical scheme, the coil spring provides a rotating force for the cleaning baffle plate at all times, so that the side wall of the cleaning baffle plate close to the storage tank is always attached to the storage tank. During the rotation of the stirring assembly, the cleaning baffle plate is driven to move on the inner wall of the storage tank, thereby achieving the cleaning effect in the storage tank.

[0015] Optionally, the stirring rod is provided with a receiving groove, and the cleaning strip is located in the receiving groove in a receiving state; the stirring rod is provided with a first cleaning ring which is slidably arranged on the stirring rod and sleeved on the outer wall of the stirring rod, and the inner wall of the first cleaning ring abuts against the outer wall of the stirring rod; the stirring rod is fixed with a magnet, and the magnet is located on the groove wall of the receiving groove close to the vertical rod; and the magnet is used for magnetically attracting the first cleaning ring, and the inner wall of the first cleaning ring abuts against the magnet and the cleaning strip at the same time when the cleaning strip is in the receiving state.

[0016] By adopting the above technical scheme, the cleaning strip is received in the receiving groove only when the slurry in the storage tank is stirred, the first cleaning ring is magnetically attracted to the magnet, and the first cleaning ring limits the cleaning strip in the receiving groove, thereby reducing the amount of slurry adhered to the cleaning strip; when the residual slurry in the storage tank needs to be cleaned, the first cleaning ring is slid to scrape off the slurry adhered to the outer wall of the stirring rod and the outer wall of the cleaning strip, and then the cleaning strip is unfolded to scrape off the slurry adhered to the inner wall of the storage tank, thereby completing the cleaning of the inside of the storage tank.

[0017] Optionally, the stirring rod is provided with a protection box, and the coil spring is located in the protection box.

[0018] By adopting the above technical scheme, the protection box avoids the coil spring from being contaminated by the slurry, thereby ensuring that the coil spring can be normally used.
