Description

Technical Field

[0001] This invention relates to the field of coal engineering technology, specifically to a modified loess and loess brick production line and a loess brick stacking machine. Background Technology

[0002] For safety and technical reasons, coal mines need to seal off certain roadways.

[0003] The traditional technique for permanently sealing a tunnel involves building a brick wall at each end of the tunnel and backfilling the gap between the two walls (the filling area). North China, including West China, is rich in natural loess resources, and using loess for permanent sealing offers significant environmental and cost advantages.

[0004] After backfilling the filling area with loess, the loess needs to be compacted. Manual compaction is difficult after backfilling the upper part of the filling area, so concrete is often poured or chemical composite materials are used for filling. Traditional processes are complex, require various mechanical equipment, and are costly in terms of equipment and materials.

[0005] Underground coal mine construction conditions are more difficult than aboveground conditions. Permanent sealed filling areas are backfilled and compacted manually, and then concrete is poured or chemical composite materials are filled in. The operation time is long, and there are not only high safety risks, but also high labor intensity and construction costs.

[0006] There is a need to invent a modified loess and loess brick production line and a loess brick stacking machine to quickly complete the backfilling and compaction of the filling area. Summary of the Invention

[0007] The technical problem to be solved by this invention is to provide the coal industry with a production line for modified loess and loess bricks, as well as a loess brick stacking machine.

[0008] To solve the above problems, the basic technical solution of this invention is: to improve natural loess using the patented technology of this invention, so that the loess expands after the water content increases; to produce loess bricks using a loess brick production line; and to stack loess bricks using a loess brick stacking machine to quickly complete the backfilling and compaction of the filling area.

[0009] Loess is improved by adding expansive and / or cementitious materials. The increased water content in the modified loess causes it to expand, achieving the goal of compacting and filling underground tunnels.

[0010] The loess selected is dry, free of impurities, natural loess.

[0011] The modified material is an expansive-based material, with bentonite being the preferred choice.

[0012] The expansion rate of loess can be controlled by adjusting the parameters of the expansive substrate material.

[0013] The maximum expansion rate of the modified loess meets the requirements for dense filling tunnels.

[0014] Based on the different requirements of tunnel geological conditions and sealed construction for loess bricks, as well as the different soil types of loess, cementitious building materials are added to the modified materials.

[0015] The parameters of expanded base materials should take into account material costs.

[0016] To control loess expansion, either passive expansion technology or active expansion technology can be selected.

[0017] Passive expansion technology involves controlling the amount of water used to form loess bricks during the production process. After the stacking machine places the loess bricks in the tunnel, the groundwater in the mine causes the modified loess to expand, the loess bricks to crack, and the loess to continue to expand, thus achieving the purpose of densely filling the mine tunnel.

[0018] Active expansion technology controls the amount of water used to form loess bricks during the production process. After the stacking machine places the loess bricks in the tunnel, water is sprayed into the tunnel through pre-buried water pipes. This causes the modified loess to expand, the loess bricks to crack, and the loess to continue to expand, thus compacting and filling the tunnel.

[0019] Using a loess production line to produce loess bricks, the loess brick stacking machine can quickly place the loess bricks in the filling area.

[0020] A loess brick production line includes a loess mixing plant, a loess brick-making machine, a power supply, and a control system.

[0021] The loess brick production line is installed indoors in the loess brick production workshop, which is a rainproof building.

[0022] A loess mixing plant includes a feed silo, a mixer, and a water storage tank.

[0023] The feed silos include loess feed silos, expanded base material feed silos, and cementitious base material feed silos.

[0024] Each feed hopper outlet is equipped with an electric valve.

[0025] Each feed hopper is equipped with a weight sensor and a loess moisture content sensor.

[0026] A feed conveyor belt is installed between the feed hopper outlet and the mixer inlet, and the conveyor belt is equipped with a conveyor belt motor.

[0027] The mixer includes a feed inlet, a mixing chamber, mixing blades, a mixing motor, a discharge outlet, and a discharge outlet electric valve.

[0028] The water storage tank is equipped with an electric valve, water pipes, and a flow-limiting orifice plate.

[0029] A discharge conveyor belt is installed below the discharge port of the mixer, connecting to the feed port of the loess brick-making machine. The conveyor belt is equipped with a motor.

[0030] The loess brick making machine includes a main unit, a brick making machine feed inlet, loess brick molds and hydraulic pumps, loess brick pallets and loess brick conveyor belts.

[0031] The main body of the loess brick-making machine is made of steel.

[0032] Loess brick molds consist of an upper mold, a mold cavity, and a lower mold.

[0033] The mold cavity is located above the lower mold, and the upper mold is located above the mold cavity. The mixed loess enters the mold cavity through the feed inlet of the loess brick making machine, and the upper mold presses down to form loess bricks.

[0034] Hydraulic pumps and hydraulic control devices include hydraulic pumps, hydraulic tanks, and hydraulic sensors.

[0035] The hydraulic pressure is controlled by controlling the frequency of the hydraulic pump motor.

[0036] The loess brick pallet is equipped with a pallet motor.

[0037] Different sizes of loess bricks require different types of loess brick molds.

[0038] A loess brick-making machine can form multiple loess bricks in one operation.

[0039] The loess brick conveyor belt connects the loess brick pallets and the loess brick transport vehicle. The conveyor belt is equipped with a motor. The loess production line is powered by mains electricity.

[0040] The control system of the loess production line includes a power distribution box, an electrical control cabinet, a PLC, and a human-machine interface control panel.

[0041] The PLC and the electric valves at the feed hopper outlet, feed conveyor motor, mixing motor, water storage tank, and mixer discharge outlet of the loess mixing plant, as well as the hydraulic pump, loess brick pallet motor, and discharge conveyor motor of the loess brick making machine, are connected via wired communication.

[0042] The PLC controls the electric valves at the feed hopper outlet, feed conveyor motor, mixer motor, water tank electric valve, and mixer discharge outlet of the loess mixing plant; the hydraulic pump, loess brick pallet motor, and discharge conveyor motor of the loess brick making machine; and the start and stop of the loess brick conveyor motor, and monitors their operating status.

[0043] The PLC receives online data from the weight sensor of the loess mixing plant's feed hopper, the loess moisture sensor, and the hydraulic sensor of the loess brick-making machine.

[0044] Operators set various operating parameters for the loess production line using the human-machine interface control panel.

[0045] Electrical control and protection are fed into the PLC.

[0046] The loess brick stacking machine includes a walking system, a mechanical claw, and a mechanical claw control panel.

[0047] For the mobility system, choose an explosion-proof forklift.

[0048] The mechanical gripper is mounted on the forklift forks.

[0049] The mechanical gripper is powered by the generator of the explosion-proof forklift.

[0050] The mechanical claw control panel is installed in the explosion-proof forklift operator's cab and is linked to the forklift's operating system.

[0051] The forklift driver uses a mechanical gripper to grab and stack loess bricks.

[0052] The robotic gripper can grab and stack one or more loess bricks at a time.

[0053] Furthermore, loess bricks are produced according to the work assignments issued by the coal mine dispatch center. Loess brick production follows the principle of producing and using them on the same day.

[0054] The laboratory provides loess brick production formulas, which include loess brick model specifications, the amount of loess, expansive base material and cementitious base material, the amount of water added when mixing loess, the mixing time, the hydraulic pressure and hydraulic time for forming loess bricks, and the expansion rate of loess bricks.

[0055] Based on data from the loess moisture sensor in the feed hopper, the PLC adjusts the water usage and the feed weight to the mixer accordingly, based on the laboratory formula. The opening, duration, and closing of the water storage tank's electric valve are also controlled by the PLC.

[0056] The PLC determines the mixing time based on the laboratory loess brick formula and the amount of material to be mixed at one time. Once the mixing time is complete, the PLC instructs the electric valve at the mixer outlet to open, allowing the modified loess to enter the brick-making machine's feed inlet.

[0057] The PLC determines the hydraulic pressure and the pressing time for the loess bricks based on the laboratory formula and the specifications of the loess bricks. Once the pressing time is complete, the hydraulic pump stops working.

[0058] Develop infill construction operation documents, including the placement and height of the loess bricks.

[0059] Quantity of loess bricks = Tunnel volume ÷ (1 + modified loess expansion rate) / Volume of a single loess brick.

[0060] Furthermore, a vibratory motor is used instead of a hydraulic pump. The loess brick-making machine includes a main unit, a brick-making machine feed inlet, loess brick molds, a vibratory motor, loess brick support plates, and a loess brick conveyor belt. The upper mold vibrates and presses down, forming loess bricks.

[0061] Furthermore, the loess brick production workshop is equipped with loess stockpiles and expanded base material stockpiles, with loaders used for feeding. Cementitious base materials are stored directly in the feed silo.

[0062] Based on the work tasks issued by the coal mine dispatch center, the operators select the loess brick model, specifications, formula, and quantity on the human-machine interface control panel, and start the automatic operation of the loess brick production line.

[0063] The PLC calculates the number of mixing cycles required to complete the task based on the mixer's discharge capacity; it calculates the amount of water and loess needed to be adjusted for each mixing cycle based on the data returned by the loess moisture sensor; and it determines the amount of loess required for each brick making cycle by the loess brick making machine based on the loess brick model and specifications, and also determines the opening duration of the electric valve at the mixer's discharge port.

[0064] The PLC commands the outlet electric valve of the feed hopper to open, and then commands the feed conveyor belt motor to start. Loess, expanded base materials, and cementitious base materials enter the mixing chamber via the feed conveyor belt. Weight sensors display the weights of the loess, expanded base materials, and cementitious base materials.

[0065] The opening and closing of the electric valve at the feed hopper outlet is controlled by the PLC; the PLC confirms the feeding is complete based on the data returned by the feed hopper weight sensor, and then instructs the electric valve at the feed hopper outlet to close.

[0066] The PLC commands the mixing motor to start, and begin mixing loess, expanded base materials, and cementitious base materials.

[0067] The PLC commands the water tank's electric valve to open, adding water to the mixing chamber; when the water adding time ends, the PLC commands the water tank's electric valve to close.

[0068] Once the loess mixing is complete, the PLC commands the conveyor belt motor to start, and commands the electric valve at the mixer outlet to open, transferring the mixed loess to the loess brick-making machine inlet.

[0069] The PLC, based on the amount of loess required for a single brick-making operation by the loess brick-making machine, commands the electric valve at the mixer's discharge port to close in a timely manner.

[0070] The PLC commands the hydraulic pump to start, and the hydraulic control device presses the loess bricks. Once the loess brick pressing is complete, the PLC commands the hydraulic pump to stop.

[0071] The PLC commands the loess brick pallet motor to start, and the loess brick pallet transfers the loess bricks to the loess brick conveyor belt.

[0072] The PLC commands the loess brick conveyor belt motor to start, which will then transport the loess bricks to the loess brick transport vehicle for loading.

[0073] Repeat the above process to press all the loess mixed in the mixer into loess bricks.

[0074] Repeat the above process: the mixer remixes the loess, and the loess brick-making machine presses the loess bricks until the task is completed.

[0075] When the loess brick transport truck arrived at the construction site, the forklift driver unloaded the loess bricks from the truck and stacked them in the corresponding positions according to the construction operation documents.

[0076] Furthermore, in emergency rescue operations, it can quickly fill tunnels and assist other equipment in rapidly sealing them off.

[0077] The PLC commanded all devices to stop operating.
