[0002] In the field of coal mining technology, longwall mechanized mining is the most widely used method in my country. Advances in mining technology and equipment have greatly improved mining efficiency. However, this still relies on maintaining coal pillars 15-50 meters wide between working faces to ensure stope stability, resulting in significant amounts of compressed coal that cannot be mined. The integrated excavation, filling, and retention inter-face coal pillar replacement technology addresses this issue through a process of "large-section excavation, intermediate backfilling, and retaining lanes along the backfill pillars."

[0003] The excavation, filling and retention method completes the recovery of coal pillars between faces and the retention of mining tunnels through an integrated process of large-section tunnel excavation, middle filling, and natural tunnel formation on both sides.

[0063] The following combination Figures 1 to 17 The embodiment shown in the figure describes the technical solution of the present invention: Figures 1 to 3 As shown:

[0064] The embodiment of the present invention provides a concrete floor forming and laying device for use in coal mining construction, comprising: a template portion 1, a chassis portion 2, a vibrating portion 3, a traction portion 5, and a control module, wherein:

[0065] The chassis part 2 is arranged at the front end of the template part 1 along the forward direction of the equipment and is connected to the template part 1; the vibrating part 3 is arranged above the template part 1 and is telescopically connected to the template part 1 in the vertical direction;

[0066] The formwork portion 1 has a semi-enclosed casting cavity 105, and the vibrating portion 3 has a vibrating rod 301, which can extend vertically into the casting cavity 105;

[0067] The chassis portion 2 includes a chassis body 201 and a flexible film bag conveying mechanism 202, a cutting mechanism 203, and a flexible film bag storage mechanism 204 disposed within the interior of the chassis body 201. The flexible film bag conveying mechanism 202 is capable of extending and retracting in both the backward and forward directions of the device and conveys flexible film bag bodies 2042 from the flexible film bag storage mechanism 204 into the casting cavity 105. The cutting mechanism 203 is disposed above the flexible film bag conveying mechanism 202 and is used to cut the flexible film bag bodies 2042.

[0068] The template portion 1 is provided with a grouting portion 4, which includes a grouting port 401. The grouting port 401 is provided with a first solenoid valve 402 for on-off control of the grouting port 401. The traction portion 5 is provided at the front end of the chassis portion 2 for traction of the equipment.

[0069] The control module is electrically connected to the flexible film bag conveying mechanism 202 , the cutting mechanism 203 , the vibrating unit 3 , the first solenoid valve 402 and the pulling unit 5 , respectively.

[0070] It is understandable that the control module may preferably be a single-chip integrated circuit module, such as PIC16F877A or PIC18F4520 of the PIC series.

[0071] The embodiment of the present invention provides a concrete floor forming and laying device for use in coal mining and filling construction. Through the configuration of a template unit 1, a chassis unit 2, a vibrating unit 3, a traction unit 5, and a control module, it can realize the automated forming and laying of concrete floors in the transport chute of an excavated tunnel, thereby effectively solving the problem of low forming and laying efficiency. Specifically:

[0072] By arranging the chassis portion 2 at the front end of the template portion 1 along the forward direction of the equipment and connecting it to the template portion 1, the template portion 1 can be pulled and sufficient expansion and contraction space can be provided for the soft film bag conveying mechanism 202; by arranging the soft film bag conveying mechanism 202 in the chassis body 201, the soft film bag body 2042 can be automatically conveyed into the pouring cavity 105, providing a base plate foundation for pouring concrete and preventing concrete slurry from seeping out of the roadway ground; by arranging the cutting mechanism 203 in the chassis body 201, the soft film bag body 2042 can be cut to ensure the automatic and intermittent conveying of the film bag body by the soft film bag conveying mechanism 202; by arranging the soft film bag storage mechanism 204, a large number of soft film bag bodies 2042 can be stored, so as to provide sufficient soft film bag bodies 2042 for the soft film bag conveying mechanism 202;

[0073] By arranging a plurality of vibrating rods 301 on the vibrating portion 3, and by allowing the vibrating rods 301 to extend vertically into the casting cavity 105, it is possible to automatically vibrate the concrete slurry before initial setting and final setting.

[0074] By providing a grouting port 401 in the formwork portion 1 and providing a first electromagnetic valve 402 at the grouting port 401 , automatic control of the concrete entering into the formwork portion 1 can be achieved.

[0075] According to the concrete bottom plate forming and laying equipment provided by the embodiment of the present invention, Figures 4 to 7 As shown, the formwork portion 1 includes: a plurality of side panels and a top panel 106, wherein the plurality of side panels and the top panel 106 enclose a casting cavity 105, and the top panel 106 has an inclined angle so that the cross section of the casting cavity 105 is a right-angled trapezoidal quadrangular prism;

[0076] The top plate 106 is provided with a plurality of through holes 107 , which are arranged in a lattice pattern;

[0077] The vibrating unit 3 includes a plurality of vibrating rods 301 arranged in a lattice manner and a first telescopic mechanism 303. The plurality of vibrating rods 301 are connected to the first telescopic mechanism 303. Under the telescopic action of the first telescopic mechanism 303, the vibrating rods 301 can pass through the through hole 107 and extend into the casting cavity 105.

[0078] The first telescopic mechanism 303 includes a base plate 302 and a plurality of first electric telescopic rods, wherein the base plate 302 is arranged horizontally, the vibrating rod 301 is arranged to pass through the base plate 302 in the vertical direction, and the plurality of first electric telescopic rods are arranged below the base plate 302 in the vertical direction, with one end connected to the base plate 302 and the other end connected to the top plate 106; the first electric telescopic rods are also electrically connected to the control module.

[0079] It is understood that the side panels and the top panel 106 are both made of steel formwork and are tightly connected to each other using bolt assemblies. The enclosed cavity is the casting cavity 105. The dot matrix formed by the vibrating rods 301 is a 6*7 rectangular array. Correspondingly, the through holes 107 are also a 6*7 rectangular array, and the through holes 107 are opened in the vertical direction.

[0080] Therefore, by setting the formwork part 1 as a plurality of steel formworks, it is convenient to obtain and assemble materials; at the same time, the casting cavity 105 is set as a quadrangular prism with a right-angled trapezoidal cross section, the top surface of the cast concrete bottom plate can be an inclined surface, and then the slope is automatically found and formed, avoiding manual slope finding and leveling, and improving the forming efficiency; by setting the vibrating part 3 as a mechanism consisting of a plurality of vibrating rods 301 arranged in a lattice manner and a first telescopic mechanism 303, it is possible to achieve that the plurality of vibrating rods 301 move up and down simultaneously in the vertical direction, so that after pouring, the concrete bottom plate is in the initial setting state, the vibrating rods 301 vertically descend into the concrete bottom plate slurry, vibrate once, and then vertically lift; before the final setting state, the vibrating rods 301 vertically descend into the concrete bottom plate slurry, vibrate once, and then vertically lift; this meets the industry standard requirements for vibration, and at the same time improves the vibration efficiency and vibration effect;

[0081] During the specific implementation process, the start of the first telescopic mechanism 303 and the vibrating rod 301 can be controlled by a single-chip microcomputer. The initial setting time and final setting time, as well as the start and stop time are preset. When the time point is reached, the first telescopic mechanism 303 and the vibrating rod 301 are controlled to start and stop.

[0082] When pouring is required, the first solenoid valve 402 is opened. At this time, the first telescopic mechanism 303 controls the vibrating rod 301 to descend until the lower end surface of the vibrating rod 301 is flush with the lower end surface of the top plate 106. In this way, relative sealing of the grouting can be achieved, so that part of the slurry will not splash out. The exhaust only needs to be exhausted through multiple small exhaust holes 109 opened on the top plate 106. Therefore, the lower end surface of the vibrating rod 301 should be set to an inclined surface with the same slope as the top plate 106.

[0083] According to the concrete bottom plate forming and laying equipment provided by the embodiment of the present invention, Figures 4 to 7 As shown, the side panels on both sides perpendicular to the forward direction of the device are respectively a left side panel 101 and a right side panel 102, and the side panel provided on the rear end surface is a rear panel 103;

[0084] The rear end faces of the left side panel 101 and the right side panel 102 are respectively provided with electromagnetic strips 110, and the rear panel 103 is provided with a metal magnetic strip 111. When the rear panel 103 is connected to the left side panel 101 and the right side panel 102, the electromagnetic strip 110 and the metal magnetic strip 111 cooperate with each other; the electromagnetic strip 110 is electrically connected to the control module.

[0085] In the specific implementation process, the electromagnetic strip 110 is electrically connected to the controller, and the controller is electrically connected to the single-chip microcomputer; the metal magnetic strip 111 can preferably be an iron strip; when the electromagnetic strip 110 is energized, it is tightly adsorbed to the metal magnetic strip 111, and when the power is off, they are not adsorbed; the electromagnetic strip 110 is in an energized state in the initial state of the device, and after the first concrete bottom plate body 6 is poured, when the device is ready to move forward, it is in an off-state, so that the entire device can move forward smoothly under the action of the traction part 5 without being affected by the rear plate 103 (see Figure 16 ).

[0086] According to the concrete bottom plate forming and laying equipment provided by the embodiment of the present invention, Figures 8 to 11 As shown, the side panel provided on the front face is the front panel 104;

[0089] In a specific embodiment, the internally threaded sleeve 2022 is installed on the support plate 2023 through a bearing. The first drive assembly 2024 is composed of a drive motor, a bevel gear transmission rod, and a passive bevel gear connected to the internally threaded sleeve 2022. In this way, one motor can simultaneously drive the two internally threaded sleeves 2022 to rotate, thereby ensuring the synchronization of the movement of the screw 2021. The structure of the clamping head 2025 will be described below. The clamping head 2025 is in a clamping and closed state when conveying the flexible film bag body 2042. When the clamping head 2025 is extended into place and stays for a certain preset period of time, it releases the clamping for recycling and is in an open state when retracting.

[0090] The purpose of the preset dwell time is to allow the slurry to be poured onto the flexible film bag body 2042 first. Once the slurry has a certain weight, it can press down the flexible film bag body 2042. At this time, the retrieving clamping head 2025 will not bring back the flexible film bag body 2042.

[0091] A through window 112 is provided at the lower part of the front plate 104, and a window door 113 is rotatably provided on the rear side of the through window 112. The window door 113 is connected to a second drive assembly, which may preferably be a reduction motor, which is electrically connected to the single-chip microcomputer. When the clamping head 2025 is ready to pass through the window 112, the reduction motor is started, driving the window door 113 to flip up 90° and open. When the clamping head 2025 is retracted into the chassis body 201, the reduction motor is started, driving the window door 113 to flip down 90° and close. A step structure is formed on both the through window 112 and the window door 113, so that slurry is not seeped through.

[0092] Therefore, by setting up the screw 2021 driven flexible film bag conveying mechanism 202, the flexible film bag body 2042 can be automatically conveyed and laid, thereby avoiding the problem of low efficiency caused by manual operation.

[0093] According to the concrete bottom plate forming and laying equipment provided by the embodiment of the present invention, Figures 12 to 14As shown, the clamping head 2025 includes a base plate 20251, the base plate 20251 is fixedly connected to the screw rod 2021, a first clamping plate 20252 is fixedly connected to the rear end of the base plate 20251, a slide groove 20254 is opened on the upper surface of the base plate 20251 along the front and rear directions, the slide groove 20254 is also slidably connected to the second clamping plate 20253, the first clamping plate 20252 is arranged parallel to the second clamping plate 20253, and the slide groove 20254 is arranged along the front and rear directions. A first guide rod 20256 is provided in the rear direction, and the first guide rod 20256 passes through the second clamping plate 20253, and the first guide rod 20256 is provided with a first compression spring 20257, and the first compression spring 20257 gives the second clamping plate 20253 a moving force toward the first clamping plate 20252; the front end face of the second clamping plate 20253 is fixedly connected with a first electromagnetic telescopic rod 20255, and the first electromagnetic telescopic rod 20255 is electrically connected to the control module.

[0094] In a specific application, when the first electromagnetic telescopic rod 20255 is not energized and under the action of the first compression spring 20257, the first clamping plate 20252 and the second clamping plate 20253 are in a normally closed state, that is, a clamping state. When they need to be released, the first electromagnetic telescopic rod 20255 is energized, and the first electromagnetic telescopic rod 20255 will be in a energized state.

[0095] According to the concrete bottom plate forming and laying equipment provided by the embodiment of the present invention, Figures 12 to 13 As shown, the cutting mechanism 203 includes: a second electromagnetic telescopic rod 2031, a second guide rod 2032, a cutting knife 2033 and an electric heating unit, wherein the second electromagnetic telescopic rod 2031 has at least two mutually parallel arrangements, and is vertically arranged in the chassis body 201 and electrically connected to the control unit; the second guide rod 2032 has at least two mutually parallel arrangements, and is vertically arranged in the chassis body 201; the cutting knife 2033 is slidably connected to the second guide rod 2032 with the blade facing downward, and is also connected to the second electromagnetic telescopic rod 2031, and the second electromagnetic telescopic rod 2031 is used to provide downward movement force to the cutting knife 2033; the electric heating unit is arranged in the cutting knife 2033 and is electrically connected to the control unit; wherein the cutting knife 2033 is directly above the clamping space formed by the first clamping plate 20252 and the second clamping plate 20253, and at this time the clamping head 2025 is in the initial position.

[0096] In a specific application, a second compression spring is provided on the extension of the second electromagnetic telescopic rod 2031. This ensures that the cutting blade 2033 is always in an elevated state when the second electromagnetic telescopic rod 2031 is not energized. Only when the flexible film bag body 2042 needs to be cut, the second electromagnetic telescopic rod 2031 is energized, and the cutting blade 2033 quickly moves downward to cut. When the cutting blade 2033 descends into place, it does not touch the base plate 20251 of the clamping head 2025. This ensures that the two do not collide with each other, thereby preventing deformation and extending the service life. Therefore, when the second electromagnetic telescopic rod 2031 is installed, the height difference between the two should be adjusted.

[0097] The cutting blade 2033 is hollow and contains a heating wire. This heating wire is electrically connected to the control module and is preset to a heating temperature of 150°C. One minute before the cutting blade 2033 is ready to cut, it is powered on and preheated. When the heating wire contacts the flexible film bag body 2042, the flexible film bag body 2042 is melted.

[0098] When the cutting knife 2033 drops into place, the first electromagnetic telescopic rod 20255 is powered off. Under the action of the first compression spring 20257, the first clamping plate 20252 and the second clamping plate 20253 clamp the cutting knife 2033 therein. After the cutting knife 2033 stays for 1 minute, it is automatically lifted. At this time, the first clamping plate 20252 and the second clamping plate 20253 clamp the new soft film bag body 2042 therein, thus realizing the cyclic reciprocating actions of conveying, cutting, and clamping the soft film bag body 2042.

[0099] According to the concrete bottom plate forming and laying equipment provided by the embodiment of the present invention, Figure 15 As shown, the soft film bag storage mechanism 204 includes: a reel 2041 and a guide plate 2043, wherein the reel 2041 is installed in the chassis body 201 in a rotatable manner along the left and right directions, and is wound with a soft film bag body 2042; the soft film bag body 2042 extends along the tangential direction of the upper part of the reel 2041 and extends to the soft film bag conveying mechanism 202; the guide plate 2043 is an arc-shaped plate, which is fixedly installed in the chassis body 201, with the front end close to the protruding end of the soft film bag body 2042 and the rear end close to the clamping head 2025, and the guide plate 2043 is above the soft film bag conveying mechanism 202.

[0100] Thus, a large number of flexible film bag bodies 2042 can be rolled and stored, and guided to the initial position of the clamping head 2025 by the guide plate 2043, which facilitates the clamping of the clamping head 2025 and protects the flexible film bag conveying mechanism 202 from being affected.

[0101] According to the concrete bottom plate forming and laying equipment provided by the embodiment of the present invention, Figure 2 and Figure 16 As shown, the traction part 5 includes a hydraulic telescopic arm, one end of which is fixedly connected to the front end surface of the chassis body 201 and is used for connection with the tunnel walking support bracket.

[0102] In practice, the hydraulic telescopic arm is mounted on the chassis body 201, with its other end connected to the roadway travel support. The arm moves in steps. After a concrete base plate 6 solidifies, it moves forward one step to continue pouring. Movement and stopping are measured using a preset time, which is the setting time of the concrete slurry and is preset in the control module based on experience.

[0103] According to the concrete bottom plate forming and laying equipment provided by the embodiment of the present invention, Figure 17 As shown in the figure, a schematic diagram of the use of concrete base plate forming and laying equipment and bridge bracket 7 is shown. Since the concrete base plate forming and laying equipment occupies the road surface, other construction personnel and vehicles need to bypass the concrete base plate forming and laying equipment, so the bridge bracket 7 is arranged above the equipment; the bridge bracket 7 is connected to the traction part 5 of the equipment on both sides, that is, it moves synchronously with the equipment.

[0104] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
