Description

Technical Field

[0001] The invention belongs to the technical field of fluidized soil backfilling, and in particular relates to an intelligent mobile fluidized soil production base station and a use method thereof. Background Art

[0002] With the rapid development of the construction industry, foundation pit backfilling has become an important part of construction. The traditional foundation pit backfilling method mainly relies on manual operation and simple mechanical equipment. This method is not only inefficient, but also has many problems, such as low operating accuracy, difficult to ensure backfilling quality, and poor construction safety. In addition, the mixing and transportation of backfill materials often rely on multiple independent equipment. The combined use of such equipment often leads to cumbersome operation, low efficiency, and coordination problems between equipment. As a new type of backfill material, fluidized soil has excellent fluidity and filling properties, and has gradually been used in foundation pit backfilling. The production process of fluidized soil includes the mixing and stirring of soil, water and curing agent, as well as the transportation and precise backfilling of the mixture.

[0033] A method for using the aforementioned intelligent mobile fluidized soil production base station comprises the following steps:

[0034] S1. Loading preparation:

[0035] S11. Material preparation:

[0036] Backfill soil, solidifying agent and water are the basic raw materials for producing fluid soil;

[0037] The feeding part is responsible for conveying these raw materials to the fluidized soil mixing part;

[0038] S12. Material transportation:

[0039] The auger is driven by the auger motor and transports the material to the fluid soil mixing part through the auger pipe;

[0040] S13, curing agent grinding:

[0041] The ball mill part is used to further grind the curing agent into powder to ensure its uniform mixing;

[0042] The ground curing agent falls into the feed trough through the discharge plate, and then is transported to the feed hopper by the auger;

[0043] S14. Water supply:

[0044] The water pump in the water supply part transports water from the water tank through a long pipe to the hopper;

[0045] S2. Liquid soil production:

[0046] S21, material transport to the mixing part:

[0047] The raw materials are fed into the feeding hopper of the fluidized soil mixing part through the feeding part;

[0048] S22, stirring process:

[0049] The hydraulic push rod a controls the position of the baffle a to control the feeding hopper part so that the mixing hopper part can feed the material when the mixing hopper part takes the material;

[0050] The stirring paddle lifting part can control the lifting and lowering of the stirring paddle part. When the stirring paddle lifting part controls the stirring paddle part to be inserted into the stirring bucket part, the stirring paddle starts to stir the materials in the stirring bucket. After the stirring is completed, the stirring paddle part is pulled out of the stirring bucket part. When one of the stirring bucket parts is stirring, the other stirring bucket parts are transporting or unloading and taking materials. After the stirring is completed, the stirring bucket part that has completed the stirring is transported to the other side for unloading and taking materials, and the other stirring bucket parts will be transported to the bottom of the stirring paddle part, and the stirring paddle lifting part controls the stirring paddle part to be inserted into another stirring bucket part that has finished taking materials for stirring. Thus, multiple stirring bucket parts can work cyclically between taking materials, unloading materials and stirring.

[0051] S23. Transportation of mixing bucket:

[0052] The stepper motor a drives the gear a to rotate, thereby driving the motor fixing plate a and the connecting plate to move on the slide rail, thereby driving the mixing bucket part to realize the transportation of the mixing bucket part;

[0053] S24, processing after stirring is completed:

[0054] The mixed fluid soil is temporarily stored in the storage tank;

[0055] The mud pump then pumps the fluidized soil from the storage tank to the feed trolley for precise delivery;

[0056] S3. Fluidized soil transportation:

[0057] S31, Operation of the feeding trolley:

[0058] The control box first controls the feeding trolley to move to the construction position where the fluidized soil is required to be poured. Then the control box controls the reduction motor in the slewing bearing and the electric push rod in the mechanical arm to lift the discharging part to the appropriate position for precise feeding.

[0059] The structure of the mechanical arm: the electric push rod a is used to control the angle between the telescopic arm and the slewing bearing; the electric push rod b is used to control the extension and retraction of the telescopic arm;

[0060] S32, discharging operation:

[0061] The mud pump pumps the fluidized soil from the storage tank to the flange pipe for precise transportation; the flange pipe is only the outlet of the fluidized soil. The discharge part cooperates with the mechanical arm part to control the position of the flange pipe to accurately transport the fluidized soil to the position where it needs to be poured; and the position of the flange pipe can be changed during pouring to achieve more uniform pouring;

[0062] The stepper motor b drives the rotating support to rotate, thereby controlling the discharge angle of the flange pipe, thereby achieving precise feeding;

[0063] S4. Move and adjust:

[0064] S41. Work of the powered walking part:

[0065] The crawler chassis is driven by a reduction motor, which enables the device to move on the construction site;

[0066] The slewing bearing allows the device to rotate in different directions to adapt to different construction environments;

[0067] S42, Control:

[0068] The hydraulic station provides power for the hydraulic motor and hydraulic push rod.

[0069] Compared with the prior art, the present invention has the following advantages and effects:

[0070] The innovations of the present invention are mainly reflected in the following aspects:

[0071] 1. Mobile design: The present invention provides an intelligent mobile fluidized soil production base station, which integrates fluidized soil mixing, loading, powered walking and material conveying functions. The device can be flexibly moved to meet the needs of different construction sites, improving the convenience and efficiency of construction.

[0072] 2. Integrated fluidized soil production and transportation system: This device integrates the production of fluidized soil including mixing, loading and transportation. It can directly produce and transport fluidized soil to the designated location at the construction site, reducing intermediate links and reducing construction costs.

[0073] 3. Optimized design of the fluidized soil mixing part: The design of the integral part of the mixing paddle and the mixing bucket allows the fluidized soil to be fully mixed, ensuring the uniformity of the fluidized soil. In addition, the mixing paddle part can be disassembled separately and installed on a forklift to be used as a bucket, increasing the versatility of the equipment.

[0074] 4. Circulation of mixing buckets: Two groups of mixing buckets are set in the device. By using them alternately, when one mixing bucket is mixing, the other mixing bucket can be used for transfer, unloading or taking materials at the same time. This design reduces waiting time, realizes continuous production, and greatly improves the overall production efficiency.

[0075] 5. Accurate feeding system: The feeding trolley realizes the precise feeding of fluidized soil through the combination of the mechanical arm and the discharging part. It can accurately adjust the feeding position and angle according to the construction needs, further improving the construction accuracy and efficiency.

[0076] 6. Efficient feeding and ball milling system: The auger feeding and ball mill parts of the feeding part can effectively process and transport various raw materials to ensure the continuity and efficiency of fluid soil production.

[0077] 7. Flexible power travel system: The power travel part is designed with a slewing bearing and a crawler chassis, which makes the whole device have good maneuverability and adaptability at the construction site and can cope with complex road conditions and different construction requirements.
