Description

Technical Field

[0001] This invention relates to the field of cement slipform pavers, and more particularly to a small mine slipform paver. Background Technology

[0002] With the continuous strengthening of energy security strategies and requirements for mine safety, the coal mining industry is accelerating its transformation from traditional extensive production to mechanization, automation, and intelligentization. Currently, the most common method for mine concrete construction is to have a centralized mixing plant on the surface complete the batching and mixing according to the design strength, then transport it underground in sealed containers using explosion-proof rubber-wheeled vehicles and special tanks. Manual labor, along with small machinery, is then used for paving, vibration, leveling, and finishing, followed by joint cutting and water curing. However, this method has drawbacks: long concrete transport distances can easily lead to segregation and excessively rapid initial setting, affecting construction quality; underground spaces are confined with limited ventilation, resulting in a poor working environment during unloading and paving; long-distance transport occupies hoisting and transportation systems, significantly interfering with normal mine production, and limiting overall construction efficiency. Therefore, there is an urgent need to develop a mine slipform paver adapted for underground paving, improving efficiency, maintaining the fluidity of concrete during transport and its stability after paving, and enhancing its intelligence, mechanization, and automation.

[0005] As a further embodiment of the present invention, the leveling and compaction module includes a counter-rotating helical shaft, a vibration module, and a main board. An infrared level is embedded in the rear of the leveling and compaction module. A vibration module and a depth detection sensor are welded to the top of the main board, and a bidirectional rotating shaft is connected to the bottom of the main board via a dual-axis counter-rotating module. A counter-rotating helical shaft is fixed on the bidirectional rotating shaft. The main board has a telescopic lower plate and a telescopic upper plate inside. The telescopic lower plate is connected to a variable hinge via a bearing every 5 cm. The telescopic lower plate is fixedly connected to a telescopic connecting rod, which is welded to a self-locking slider. The telescopic upper plate engages with the main board via gears, and the telescopic upper plate has upper and lower sliding grooves every 5 cm. The upper and lower sliding grooves correspond one-to-one with the variable hinges. A rotating shaft is fixed inside the vibration module, and multiple eccentric oscillators are fixed on the rotating shaft. Strong electromagnets are built into the joints of the telescopic lower plate and the telescopic upper plate on both sides of the main board.

[0006] As a further embodiment of the present invention, the sliding mold forming module is fixedly connected to the telescopic dividing plate lower plate, and a shrink plate is connected to the front end of the sliding mold forming module. The shrink plate is embeddedly connected to the shrink rounded corner. An oscillator drive rod is fixed inside the sliding mold forming module, and an oscillator is nested on the oscillator drive rod.

[0007] Compared with the prior art, the beneficial effects of the present invention are:

[0008] 1. This small mine slipform paver allows concrete to be mixed and molded in the slipform molding module by spraying an appropriate amount of quick-setting agent before entering the module, replacing the arduous manual formwork process; and the positive pressure and mechanical wave vibration generated by the vibration module make the concrete particles more compact under the pressure and mechanical wave vibration, and the concrete is evenly transported to both sides by the opposite rotating shaft spiral, and the lower plate of the telescopic partition plate and the main plate are telescopic and fixedly connected to form a flat contact surface.

[0009] 2. In terms of hardware configuration and intelligence, this small-scale mine slipform paver is equipped with an infrared level, depth sensor, and eccentric vibrator drive structure. It also employs a sealed mixing system with negative pressure design to reduce dust. For material conveying and control, in addition to basic conveying functions, it features a telescopic rotating conveying pipe, dual discharge ports, and a concrete pump, all centrally controlled via an integrated control panel in the driver's cab. Furthermore, this equipment has been completely revolutionized by addressing the shortcomings of existing technologies that rely on manual formwork (wood or high-hardness plastic), resulting in time-consuming and labor-intensive work, uneven edges, and the need for secondary trimming. It achieves a transformation from multi-device coordination to integrated automated operation.

[0010] 3. This small-scale mine slipform paver effectively promotes the mechanization of underground mine road construction. Compared with the traditional manual formwork and pouring process, it can continuously and uninterruptedly lay concrete pavement. The paving width can also be flexibly adjusted and is not limited by the range of manual formwork operations. It eliminates tedious processes such as manual formwork, formwork removal, smoothing, and edge trimming. It not only greatly improves construction efficiency and shortens the construction period, but also avoids the problems of uneven cement edges and many defects in the traditional process. It reduces a lot of labor waste and economic and time losses, and achieves high efficiency, high quality, and low consumption in underground concrete pavement construction.

Detailed Implementation

[0020] This section will describe in detail specific embodiments of the present invention. Preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but they should not be construed as limiting the scope of protection of the present invention. Example 1

[0021] Please see Figure 4This invention provides a technical solution: a small mine slipform paver, comprising a first transport box 2-4, the interior of which is treated with anti-corrosion to withstand long-term wear and chemical corrosion of concrete. A hinge 2-6 is fixed to one side of the top of the first transport box 2-4, and the other side of the hinge 2-6 is fixed to the side of the capping cover 2-3. A telescopic cylinder 2-2 is installed on a small cuboid protruding above the capping cover 2-3. The telescopic cylinder 2-2 is powered by a motor compartment 2-1 below it. The telescopic cylinder 2-2 drives the capping cover 2-3. The capping cover 2-3 opens and closes the first transport box 2-4 by rotating the hinge 2-6. When the telescopic cylinder 2-2 extends, the capping cover 2-3 descends; when the telescopic cylinder 2-2 retracts, the capping cover 2-3 rises. The motor compartment 2-1 is welded to the rear surface of the first transport box 2-4. A stirring device 2-5 is rotatably fixed inside the first transport box 2-4, which can achieve 360-degree rotation without dead angles. The mixing blades adopt a spiral design, and the blade surface is covered with a wear-resistant alloy coating. During rotation, they can thoroughly mix the concrete and enhance its fluidity, preventing clumping or segregation. A negative pressure unit 2-11 is installed on the inner surface of the first transport box 2-4. When the first transport box 2-4 is fully closed by the cooperation of the hinge 2-6 and the telescopic cylinder 2-2, the motor compartment 2-1 supplies power to the negative pressure unit 2-11 and the mixing device 2-5. The negative pressure unit 2-11 starts working, extracting air from the box through the extraction pipe to create a stable negative pressure environment. At this time, under the action of negative pressure, the mixed concrete is pressed into the slipform forming chamber 4-1 and the movable conveying pipe 2-7 through the small circular discharge port 2-12 and the large circular discharge port 2-10, respectively. Since the height of the small circular discharge port 2-12 is 7cm higher than that of the large circular discharge port 2-10, the concrete will flow into the slipform forming chamber 4-1 through the small circular discharge port 2-12 first, so as to prepare materials in advance for the slipform operation on both sides and ensure the continuity of the construction process.

[0022] Furthermore, the slipform forming chamber 4-1 is welded to both sides of the first transport box 2-4 and connected to the bottom of the first transport box 2-4 through a small circular discharge port 2-12. The top of the slipform forming chamber 4-1 is cut into a main spray port 4-4 and a secondary spray port 4-5. Before the device operates, a concrete accelerator is added to the main spray port 4-4. When concrete enters the slipform forming chamber 4-1, the electric valve of the secondary spray port 4-5 automatically opens, and the accelerator in the secondary spray port 4-5 flows rapidly into the slipform forming chamber 4-1 under gravity and air pressure, mixing thoroughly with the concrete. This design ensures that the accelerator is evenly distributed in the concrete, effectively shortening the concrete setting time and increasing the tunnel forming speed. The motor chamber 2-1 powers the concrete delivery pump 4-2, which transports the concrete with the added accelerator to the slipform forming module 7 through a detachable hose 4-3. The detachable hose 4-3 is made of high-strength rubber with a smooth inner wall and good wear resistance. Its two ends connect to the concrete pump 4-2 and the slipform forming module 7. Disassembly and installation take only 3-5 minutes. After construction, workers can remove the detachable hose 4-3 for cleaning, removing any residual concrete to prevent hardened concrete from clogging the pipes and thus extending the equipment's service life.

[0023] Furthermore, such as Figure 2 and Figure 3 The top of the movable conveying pipe 2-7 is supported by a stabilizing column 2-8, which greatly enhances the load-bearing capacity of the movable conveying pipe 4-3 and can better adapt to the large-area paving of the middle section of concrete. The movable conveying pipe 2-7 is connected to two sides by 30-degree telescopic rotating shafts 2-9. The 30-degree telescopic rotating shafts 2-9 control the movable conveying pipe 2-7 to rotate and move between 30 degrees to the left and 30 degrees to the right in a telescopic manner. There are four telescopic rotating shafts 2-9 in total. The telescopic manner is that the telescopic rotating shaft 2-9 at one end extends and the telescopic rotating shaft 2-9 at the other end retracts, so that the movable conveying pipe 2-7 rotates in the direction of the retracted telescopic rotating shaft 2-9. The rotation range is 0-60 degrees, and uniform concrete is discharged in front of the device for subsequent paving. The 30-degree telescopic rotating shaft 2-9 is welded to the second motor 3-10. The second motor 3-10 integrates an intelligent control system, which can precisely control the telescopic length and speed of the 30-degree telescopic rotating shaft 2-9 according to construction requirements, achieving smooth rotation of the movable conveying pipe 2-7. Simultaneously, the second motor 3-10 also supplies power to the slipform forming module 7, the leveling and compaction module 3, and the hydraulic cylinder 3-3, ensuring coordinated operation of all components. The hydraulic cylinder 3-3 adopts a double-acting structure, capable of pushing the leveling and compaction module 3 back and forth to compact and level the paved concrete, further improving the smoothness and density of the concrete pavement.

[0024] Furthermore, the device is controlled by the operator using the control panel 1-7, the walking control handle 1-4, and the pilot handle 1-3 to achieve walking and paving compaction. A battery device 1-8 is installed below the control panel 1-7. The battery device 1-8 provides power for machine walking, infrared level 3-1, and depth detection sensor 3-2. The infrared level 3-1 is responsible for detecting whether the paved concrete is flat, and the depth detection sensor 3-2 is responsible for monitoring the ground conditions in real time to ensure that concrete of appropriate height is poured in areas of different depths or unevenness. Example 2

[0025] Based on Embodiment 1, after power is supplied, the main board 3-4 of the leveling and compaction module 3 is symmetrically equipped with a telescopic lower plate 3-7 and a telescopic upper plate 3-15 on both sides. The end of the telescopic connecting rod 3-11 is connected to the telescopic lower plate 3-7, and the upper end of the telescopic connecting rod 3-11 is connected to a self-locking slider 3-8. The telescopic lower plate 3-7 is provided with a variable hinge 3-18 every 5 cm. The motor inside the variable hinge 3-18 rotates from 0 degrees to 90 degrees, so that the telescopic lower plate 3-7 can rotate at any variable hinge 3-18 to achieve the effect of fitting with the main board 3-4. The telescopic lower plate 3-7 can also be fixed inside the variable hinge 3-18 to keep it horizontal. During operation, the telescopic lower plate 3-7, based on preset values ​​on the control panel 1-7, bends 90 degrees at the corresponding variable hinge 3-18. Then, the internal electric drive mechanism laterally pushes the self-locking slider 3-8 to move horizontally, forcing the telescopic lower plate 3-7 to expand horizontally to a preset width. The telescopic connecting rod 3-11, driven by an internal motor, moves vertically, lowering the lower plate 3-7 to a horizontal position with the main plate 3-4 at the bottom. The main plate 3-4 is leveled on both sides by an infrared level 3-1 and a depth sensor 3-2. Then, the electric drive mechanism laterally pushes the self-locking slider 3-8 to move it tightly against the main plate 3-4. The main plate 3-4 has high-voltage electrical components on both sides. Magnet 3-19, powered by the second motor 3-10, generates a strong electromagnetic field on the vertical planes on both sides of the main board 3-4. The lower telescopic partition plate 3-7 is tightly attached to the main board 3-4 by strong magnetic attraction, forming an integrated horizontal working surface. The upper telescopic partition plate 3-15 is laterally transported by gears built into the main board and meshing with it. The part meshing with the gears on the main board 3-4 is located deep within the upper telescopic partition plate 3-15 and does not protrude. After aligning with the lower telescopic partition plate 3-7 to the preset length, the lower and upper sliding grooves 3-16 slide downwards to splice the lower telescopic partition plate 3-7. The lower telescopic partition plate 3-7 and the upper telescopic partition plate 3-15 are tightly spliced ​​together by the strong electromagnet 3-19 built into them, forming an integrated working surface. The width of the expanded working surface can be dynamically adjusted in 5-centimeter increments according to construction needs to adapt to leveling operations on roads of different widths.

[0026] Furthermore, a dual-axis reverse rotation module 3-5 is fixedly installed below the main board 3-4 with screws. A bidirectional rotating shaft 3-17 is mounted on the dual-axis reverse rotation module 3-5 via bearings. Then, an opposite-direction rotating shaft spiral 3-12 is installed through a groove on the bidirectional rotating shaft 3-17. The opposite-direction rotating shaft spiral 3-12 is driven by the dual-axis reverse rotation module 3-5. The entire spiral mechanism simultaneously and evenly transports the concrete accumulated below the main board to both sides. The conveying rate and the device's travel speed form a closed-loop control to ensure that the concrete remains evenly distributed within the coverage area of ​​the lower plate 3-7 of the telescopic divider, avoiding local accumulation or segregation. At the same time, the entire spiral mechanism plays a mixing role, preventing the concrete from accumulating on the ground and causing uneven surface density due to the ground, which could lead to defects.

[0027] Furthermore, a vibration module 3-13 is fixedly installed on top of the main board 3-4 using screws. This module includes a rotating shaft 3-14, on which multiple sets of eccentric vibrators 3-9 are nested. A variable frequency motor drives the rotating shaft 3-14, causing the eccentric vibrators 3-9 to generate high-frequency vibration. The vibration frequency can be continuously adjusted within the range of 50-200Hz under the action of the variable frequency motor, achieving different compaction effects with different frequencies. During construction, the high-frequency rotation of the vibration module 3-13 generates a vertically downward high-frequency vibration force, which is then transmitted to the concrete surface via the main board 3-4, causing the concrete particles to rearrange under the vibration of pressure and mechanical waves, reducing the porosity to below 8%, and controlling the surface flatness error within ±2mm. The amplitude and frequency generated by the vibration module 3-13 can also be adjusted in real time according to the concrete mix ratio to ensure the compaction effect of concrete of different strength grades.

[0028] Furthermore, the slipform forming module 7 is fixedly installed on the outer side of the lower plate 3-7 of the telescopic partition plate with screws. The slipform forming module 7 is made of high-strength wear-resistant alloy material, and the inner surface of the slipform forming module 7 is set as a smooth curved surface with an inclination angle of 5°-15° to the horizontal plane. During construction, the concrete is mixed with the quick-setting agent sprayed by the concrete delivery pump 4-2 to form a low-slump concrete (slump ≤50mm). Then, it is injected into the wedge-shaped space between the slipform forming module 7 and the existing concrete through the detachable hose 4-3. At this time, the vibrator drive rod 7-1 fixed with screws and the vibrator 7-2 nested on it in the slipform forming module 7 perform secondary mixing of the concrete in the slipform forming module 7, so that it is more thoroughly mixed. The constriction fillet 7-4 on the slipform forming module 7, driven by the second motor 3-10, pushes the contraction plate 7-3 to open and close the slipform forming module 7. Initially, the slipform forming module 7 is closed. Once concrete fills the slipform forming module 7 and forms a regular rectangle, the constriction fillet 7-4 drives the contraction plate 7-3 to open the slipform forming module 7, allowing the slipform process to begin. During the device's movement, the concrete automatically forms a regular rectangle under the combined constraint of gravity and the module, replacing the complex traditional manual formwork erection-pouring-removal process, thus improving forming efficiency.

[0029] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
