Description

Technical Field

[0001] The present disclosure relates to the technical field of underground support equipment, and in particular to a concrete pouring formwork system. Background Art

[0002] In mine operations, to prevent accidents that could impact production safety, such as spontaneous combustion of coal seams, the spread of harmful gases, or gas explosions, it's often necessary to construct sealed walls to promptly seal abandoned goafs, tail lanes, and connecting lanes. This isolates areas prone to spontaneous combustion, sources of harmful gases, or areas where gas accumulates. These walls must be airtight and pressure-resistant, and are typically constructed using non-combustible materials such as concrete, bricks, and stone.

[0003] Fireproofing and sealing are an important part of ventilation facility construction, and concrete wall pouring is the most important part of permanent fireproofing and sealing. The two steps of concrete wall pouring, namely, supporting and removing the formwork, are very important.

[0004] In the prior art, the following two construction methods are often used:

[0005] 1) The casting space is constructed by artificial support single columns and wooden formwork. Due to the high intensity of single support work and low support strength, there are risks such as formwork deformation and displacement and concrete leakage. The construction period is long and the disassembly of single units and formwork is complicated, which affects the overall project production progress.

[0006] 2) Flexible formwork concrete goaf-side tunnel construction technology requires coal miners to use hydraulic single-unit pillars, wooden point pillars, etc. to support the flange of the flexible formwork, and then fix the flange to the tunnel roof, or use anchor rods to fix the flexible formwork flange to the tunnel roof through hanging formwork anchor rods. When the concrete wall is poured and reaches a certain strength, the hydraulic single-unit pillars and wooden point pillars are recycled. The flexible formwork material is disposable, and the construction cost is high.

[0007] The above construction methods have disadvantages such as low automation, high work intensity, long time for disassembly and assembly of formwork, low safety factor, and long construction period. How to solve the above technical problems has become a technical problem in this field. Summary of the Invention

[0079] In order to make the purpose, technical solutions and advantages of the present disclosure more apparent, the following will describe in detail exemplary embodiments of the present disclosure with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments of the present disclosure, and it should be understood that the present disclosure is not limited to the exemplary embodiments described herein.

[0080] The disclosed embodiment provides a concrete pouring formwork system 9, which can realize automated formwork support and dismantling operations, has high construction efficiency, short construction period, and can be used multiple times, significantly improving construction safety and reducing construction costs.

[0081] The implementation of the embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0082] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, an embodiment of the present disclosure provides a concrete casting formwork system 9, comprising: two or more groups of formwork units, the two or more groups of formwork units being arranged adjacent to each other and combined for support operations, specifically for concrete formwork operations for pouring concrete walls. The figure shows a first formwork unit 7 and a second formwork unit 8. Other formwork units can be added between the first formwork unit 7 and the second formwork unit 8 to expand the support area, specifically, the support area can be expanded in the width direction;

[0083] Any formwork unit includes: a bottom platform 1, a slide mechanism 2 and a flap mechanism 3;

[0084] The bottom platform 1 is a box-type structure with a large internal space for installing major components. The front of the bottom platform 1 can be used for support operations. The front of the bottom platform 1 is basically a flat plate structure and can be used as a formwork. Adjacent formwork units can be connected by connecting devices between the bottom platforms 1 to combine adjacent formwork units.

[0085] The slide mechanism 2 is provided on the bottom platform 1. The slide mechanism 2 can be extended and retracted from the top of the bottom platform 1. After extension, the front portion of the slide mechanism 2 and the front portion of the bottom platform 1 can be combined for support operations, significantly expanding the support area in the height direction. The front portion of the slide mechanism 2 is basically a flat plate structure and can be used as a template.

[0086] The flip mechanism 3 is arranged on the top of the slide mechanism 2. The flip mechanism 3 can be flipped up and down. After flipping upward, the front part of the flip mechanism 3 and the front part of the slide mechanism 2 can be combined for support operations, further expanding the support area, especially expanding the support area at a larger height. The front part of the flip mechanism 3 is basically a flat plate structure and can be used as a template.

[0087] During the concrete formwork operation for pouring concrete walls, the lifting height of the slide mechanism 2 can be determined according to the height of the roadway. If the height of the roadway is low, the lifting height of the slide mechanism 2 can be low. If the height of the roadway is high, the lifting height of the slide mechanism 2 can be high.

[0088] like Figure 3 、 Figure 4 As shown, when the concrete casting formwork system 9 is not in use or is being transported, the slide mechanism 2 is in a lowered state, the flap mechanism 3 is in a downward flipped state, and the width and height of the concrete casting formwork system 9 are in a minimum state, which is convenient for storage or transportation.

[0089] The concrete pouring formwork system 9 in this embodiment adopts a slide plate mechanism 2 that can be automatically raised and lowered and a flap mechanism 3 that can be automatically flipped. The slide plate mechanism 2 is combined with the bottom platform 1 for support operations, and the flap mechanism 3 is combined with the slide plate mechanism 2 for support operations. It can realize automated formwork support and dismantling operations, with high construction efficiency, short construction period, and can be used multiple times, which significantly improves construction safety and reduces construction costs.

[0090] In some possible implementations, such as Figure 1 、 Figure 2 As shown, the formwork unit located at the side further includes: a plug-in plate mechanism 4, and the first formwork unit 7 and the second formwork unit 8 are respectively located at one side edge of the concrete pouring formwork system 9, and both include a plug-in plate mechanism 4;

[0091] The inserting mechanism 4 is mounted on the bottom platform 1 and the flap mechanism 3. The first inserting mechanism 411 is mounted on the flap mechanism 3, while the second inserting mechanism 412 is mounted on the bottom platform 1. These mechanisms can be extended and retracted laterally from the same side of the bottom platform 1 and the flap mechanism 3, respectively. When extended, the inserting mechanism 4 can be inserted into the inner wall of the roadway, for example, into the coal seam of the roadway, thereby securing the formwork units in the roadway and ensuring sufficient stability during the concrete wall pouring process. Since the inserting mechanism 4 needs to extend outward, it is not necessary to install an inserting mechanism 4 on the central formwork units.

[0092] During the concrete formwork operation for pouring concrete walls, the extended length of the plug-in mechanism 4 can be determined according to the width of the area where concrete needs to be poured. If the width of the area where concrete needs to be poured is smaller, the extended length of the plug-in mechanism 4 can be smaller. If the width of the area where concrete needs to be poured is larger, the extended length of the plug-in mechanism 4 can be larger.

[0093] In some possible implementations, such as Figure 1 、 Figure 2 、 Figure 5 As shown, the slide mechanism 2 includes: a sliding plate 201 and a lifting drive cylinder 202;

[0094] The sliding plate 201 is arranged on the bottom platform 1. The bottom platform 1 is provided with a storage space for accommodating the sliding plate 201 and the lifting drive cylinder 202. The bottom platform 1 is also provided with a vertical guide groove in which the sliding plate 201 can slide. A vertical slideway can be provided at the rear of the sliding plate 201 (the bottom platform 1 is provided with a corresponding protrusion) for guiding during the sliding process and strengthening the structure.

[0095] The rear portion of the sliding plate 201 is provided with a sliding top seat 203, which is provided with a connecting hole. The sliding top seat 203 can be welded and fixed to the rear portion of the sliding plate 201. The sliding plate 201 can be made of a steel plate.

[0096] The lifting drive cylinder 202 is vertically arranged on the bottom platform 1. The piston rod of the lifting drive cylinder 202 is hinged to the sliding top seat 203. When the piston rod of the lifting drive cylinder 202 is extended, it drives the sliding plate 201 to rise. After rising, the front part of the sliding plate 201 and the front part of the bottom platform 1 can be combined for support operations. When the piston rod of the lifting drive cylinder 202 is retracted, it drives the sliding plate 201 to descend.

[0097] The lifting drive cylinder 202 can be extended and retracted steplessly. During the concrete wall pouring and concrete formwork operation, the lifting height of the sliding plate 201 can be determined according to the height of the roadway. If the height of the roadway is low, the lifting height of the sliding plate 201 can be low. If the height of the roadway is high, the lifting height of the sliding plate 201 can be high.

[0098] During the lifting and lowering of the slide mechanism 2, the flip mechanism 3 also follows the lifting and lowering. Since the weight of the flip mechanism 3 is superimposed on the slide mechanism 2, in order to increase the lifting driving force, the slide mechanism 2 can be provided with two sets of lifting driving cylinders 202, and two connecting holes are correspondingly provided on the sliding top seat 203. The two sets of lifting driving cylinders 202 act synchronously, and can lift the heavier slide mechanism 2 and flip mechanism 3.

[0099] The slide mechanism 2 also includes a sliding base. The cylinder barrel of the lifting drive cylinder 202 is hinged to the sliding base. The sliding base is provided with a connecting hole. The sliding base is arranged in the bottom platform 1, which is not shown in the figure.

[0100] In some possible implementations, such as Figure 1 、 Figure 2 、 Figure 5 As shown, the slide mechanism 2 further includes: a slide extension side bar 204;

[0101] The skateboard extension strip 204 is arranged on the outer side of the sliding plate 201 and is on the same side as the extension direction of the plug-in plate mechanism 4. The skateboard extension strip 204 includes multiple support rods and support plates. The support rods are detachably connected to the sliding plate 201. By installing support plates on the support rods to expand the support area, the support area of ​​the skateboard mechanism 2 is significantly expanded in the width direction.

[0102] The support rods can be made of steel bars, with corresponding connectors located on the outer sides of the sliding plates 201. The steel bars are threaded or plugged into the connectors. The support plates can be made of wooden boards, inserted into the support rods in a staggered pattern to secure them. The extended side strips 204 of the sliding plate can fill the space between the first and second plate inserting mechanisms 411, 412, to support concrete formwork during concrete wall casting.

[0103] It should be noted that the slide mechanism 2 of the formwork unit located on the side needs to be provided with a slide extension strip 204 for use with the plug-in plate mechanism 4, while the slide mechanism 2 of the formwork unit located in the middle does not need to be provided with a slide extension strip 204.

[0104] In some possible implementations, such as Figure 1 、 Figure 2 、 Figure 5 As shown, the flip mechanism 3 includes: a flip plate 301 and a flip drive cylinder 302;

[0105] The bottom of the flip plate 301 is hinged to the top of the sliding plate 201. The top edge of the flip plate 301 is provided with a first serrated structure. When the flip plate 301 is flipped upward, the first serrated structure can be inserted into the top wall of the roadway, for example, into the coal seam of the roadway, to fix the formwork unit in the roadway and provide sufficient stability during the concrete pouring process of the concrete wall. The rear of the flip plate 301 is provided with a flip top seat 304, and the rear of the sliding plate 201 is provided with a flip base 303. The flip top seat 304 can be welded and fixed to the rear of the flip plate 301, and the flip base 303 can be welded and fixed to the rear of the sliding plate 201. The flip plate 301 can be made of steel plate.

[0106] The piston rod of the flip drive cylinder 302 is hinged to the flip top seat 304, and the cylinder barrel of the flip drive cylinder 302 is hinged to the flip base 303. When the piston rod of the flip drive cylinder 302 is extended, it drives the flip plate 301 to flip upward. After flipping, the front part of the flip plate 301 and the front part of the sliding plate 201 can be combined for support operations. When the piston rod of the flip drive cylinder 302 is retracted, it drives the flip plate 301 to flip downward.

[0107] The tilting cylinders 302 are provided in a group and can be positioned between the two groups of lifting cylinders 202 so as not to interfere with the two groups of lifting cylinders 202. The tilting angle of the tilting plate 301 ranges from 0 to 90 degrees. When the tilting plate 301 is tilted downward to the lowest position, it is 0 degrees, and when it is tilted upward to the highest position, it is 90 degrees.

[0108] In some possible implementations, such as Figure 1 、 Figure 2 、 Figure 5 As shown, the flap mechanism 3 further includes: a flap extension strip 305;

[0109] The flap extension strip 305 is arranged at the top of the flip plate 301. The flap extension strip 305 includes multiple support rods and support plates. The support rods are detachably connected to the flip plate 301. By installing support plates on the support rods to expand the support area, the support area of ​​the flip mechanism 3 is significantly expanded in the height direction.

[0110] The support rods can be made of steel bars, with corresponding connectors located at the top of the flip plate 301. The steel bars are threaded or plugged into the connectors. The support plates can be made of wooden boards, inserted into the support rods in a staggered pattern to secure them. If the flip plate 301 still cannot reach the top wall of the tunnel after flipping upward, the flap extension strips 305 can fill this space and provide support for concrete formwork during concrete wall pouring. The flap mechanism 3 of both the side and center formwork units must be equipped with flap extension strips 305.

[0111] In some possible implementations, such as Figure 1 、 Figure 2 、 Figure 5 As shown, the inserting plate mechanism 4 includes: a telescopic plate 401 and an inserting plate driving cylinder 402;

[0112] The telescopic plate 401 is arranged transversely on the bottom platform 1 and the flip mechanism 3. The bottom platform 1 and the flip mechanism 3 are both provided with a receiving space for accommodating the telescopic plate 401 and the inserting plate driving cylinder 402. The bottom platform 1 and the flip mechanism 3 are also provided with a transverse guide groove, and the telescopic plate 401 can slide in the transverse guide groove;

[0113] A first connecting seat 404 is provided on the inner side of the telescopic plate 401, and a second connecting seat 403 is provided on the rear portion of the flip plate 301 and in the bottom platform 1. The second connecting seat 403 in the bottom platform 1 is not shown in the figure. The first connecting seat 404 can be welded and fixed to the inner side of the telescopic plate 401, and the second connecting seat 403 can be welded and fixed to the rear portion of the flip plate 301 and in the bottom platform 1. The telescopic plate 401 can be made of steel plate.

[0114] The plug-in plate driving cylinder 402 is laterally arranged between the bottom platform 1 and the flip plate mechanism 3. The piston rod of the plug-in plate driving cylinder 402 is hinged to the first connecting seat 404, and the cylinder barrel of the plug-in plate driving cylinder 402 is hinged to the second connecting seat 403. When the piston rod of the plug-in plate driving cylinder 402 is extended, the telescopic plate 401 is driven to extend outward. After extension, the front part of the telescopic plate 401 and the front part of the bottom platform 1 and the front part of the flip plate 301 can be combined for supporting operations. When the piston rod of the plug-in plate driving cylinder 402 is retracted, the telescopic plate 401 is driven to retract inward.

[0115] The insert plate driving cylinder 402 can be extended and retracted steplessly. During the concrete formwork operation for pouring concrete walls, the extended length of the telescopic plate 401 can be determined according to the width of the area where concrete needs to be poured. If the width of the area where concrete needs to be poured is smaller, the extended length of the telescopic plate 401 can be smaller. If the width of the area where concrete needs to be poured is larger, the extended length of the telescopic plate 401 can be larger.

[0116] In some possible implementations, such as Figure 1 、 Figure 2 、 Figure 5 As shown, the inserting plate mechanism 4 further includes: a toothed inserting plate 405, a guide plate 406, a guide seat 407, a guide rod 408 and a spring 409;

[0117] The toothed insert 405 is provided on the outer side of the telescopic plate 401 and is capable of sliding relative to the telescopic plate 401. The outer edge of the toothed insert 405 is provided with a second sawtooth structure. When the telescopic plate 401 is extended, the toothed insert 405 is driven to extend. The second sawtooth structure can be inserted into the inner wall of the roadway, for example, into the coal seam of the roadway, to fix the formwork unit in the roadway and provide sufficient stability during the concrete pouring process of the concrete wall. The toothed insert 405 can be made of steel plate.

[0118] The toothed insert 405 is provided with two or more transverse sliding grooves, and the telescopic plate 401 is correspondingly provided with a slider. The sliding grooves are sleeved on the slider, and the toothed insert 405 can be supported on the outer side of the telescopic plate 401 and can slide transversely relative to the telescopic plate 401.

[0119] The guide plate 406 is provided at the rear of the toothed inserting plate 405 and is provided with a guide hole. The guide plate 406 may be L-shaped, with the outer end of the long arm fixedly connected to the toothed inserting plate 405, and a short arm provided at the inner end of the long arm. The short arm is provided perpendicular to the telescopic plate 401, and the guide hole is provided on the short arm.

[0120] The guide seat 407 is provided at the rear of the telescopic plate 401 , and the guide seat 407 can be welded and fixed to the rear of the telescopic plate 401 ;

[0121] The guide rod 408 is inserted into the guide hole of the guide plate 406. The first end of the guide rod 408 passes through the guide plate 406 and is provided with a limit nut. The second end of the guide rod 408 is connected to the guide seat 407 and can be threaded or welded.

[0122] The spring 409 is sleeved on the guide rod 408 , with a first end of the spring 409 abutting against the guide plate 406 and a second end abutting against the guide seat 407 . The spring 409 provides elastic support for the toothed inserting plate 405 .

[0123] When extended, the toothed inserts 405 can be inserted into the inner wall of a roadway, for example, into the coal seam of the roadway, to secure the formwork unit in the roadway and provide sufficient stability during the concrete wall pouring process. During insertion into the inner wall of the roadway, the toothed inserts 405 can be pushed back an appropriate distance by the inner wall of the roadway to accommodate the varying widths and shapes of the inner wall. Compared to a rigid connection structure, this elastic connection structure can automatically adjust the telescopic length of each toothed insert 405 according to the terrain and working conditions to achieve edge sealing. This can improve the sealing between the insert mechanism 4 and the inner wall of the roadway, preventing leakage during the pouring of concrete due to large gaps.

[0124] In some possible implementations, such as Figure 1 、 Figure 2 、 Figure 6 、 Figure 7 As shown, the concrete pouring formwork system 9 further includes: a leveling mechanism 5;

[0125] The leveling mechanism 5 is provided at the lower portion of the bottom platform 1 , and the leveling mechanism 5 can adjust the horizontal state of the formwork unit.

[0126] Due to the complex and uneven ground conditions in the tunnel, during the concrete wall pouring process, if the formwork unit is not placed properly and is in a tilted state, the vertical concrete wall cannot be poured, and the stability of the formwork unit is also poor, posing a safety hazard. Therefore, it is necessary to level the formwork unit through the leveling mechanism 5 so that the formwork unit is in a horizontal state as a whole and in a vertical state, so that a qualified concrete wall can be poured, while improving the safety of the operation.

[0127] In some possible implementations, such as Figure 6 、 Figure 7 As shown, the leveling mechanism 5 includes: a leveling foot 501 and a leveling drive cylinder 502;

[0128] The leveling mechanism 5 includes at least three leveling legs 501. The three leveling legs 501 form a triangle to form a multi-point stable support structure. The shape of the leveling legs 501 can be rectangular or circular. The bottom plate of the bottom platform 1 is provided with foot holes 113 corresponding to the leveling legs 501. The leveling legs 501 can be extended and retracted from the foot holes 113. The shape of the foot holes 113 corresponds to the shape of the leveling legs 501.

[0129] The leveling drive cylinder 502 is arranged in the bottom platform 1 , and the piston rod of the leveling drive cylinder 502 is connected to the leveling support leg 501 , and can drive the leveling support leg 501 to extend from and retract from the bottom of the bottom platform 1 .

[0130] During the leveling process of the formwork unit, the extension heights of the multiple leveling legs 501 are different and are determined according to the ground conditions in the tunnel, so that the formwork unit can be adjusted to a horizontal state.

[0131] In some possible implementations, such as Figure 6 、 Figure 7 、 Figure 8 As shown, the concrete pouring formwork system 9 further includes: a hydraulic mechanism 6;

[0132] The hydraulic mechanism 6 is connected to the lifting drive cylinder 202, the flipping drive cylinder 302, the insert plate drive cylinder 402 and the leveling drive cylinder 502 through hydraulic pipelines to provide driving force. Accordingly, the lifting drive cylinder 202, the flipping drive cylinder 302, the insert plate drive cylinder 402 and the leveling drive cylinder 502 are all hydraulic cylinders with a large driving force.

[0133] In some possible implementations, such as Figure 6 、 Figure 7 、 Figure 8 As shown, the hydraulic mechanism 6 includes: a motor 104, a hydraulic pump 106, a high-low pressure switching valve 601, a control valve group 107 and a hydraulic oil tank 108;

[0134] The motor 104 may be an explosion-proof motor;

[0135] The hydraulic pump 106 can be a double gear hydraulic pump. The motor 104 is connected to the hydraulic pump 106 to drive the hydraulic pump 106 to rotate. The hydraulic pump 106 includes a front pump and a rear pump. The flow rate of the front pump is greater than the flow rate of the rear pump.

[0136] The high-low pressure switching valve 601 is used to automatically switch between the front pump and the rear pump for external output. The hydraulic pump 106 is connected to the high-low pressure switching valve 601 via a hydraulic pipeline. In the early stage of the output of the actuator (slide plate mechanism 2, flap mechanism 3, and plug-in mechanism 4), a large hydraulic flow rate is required, and the front pump is used for external output. In the late stage of the output of the actuator (slide plate mechanism 2, flap mechanism 3, and plug-in mechanism 4), a small hydraulic flow rate is required, and the rear pump is used for external output.

[0137] The control valve group 107 is connected to the high- and low-pressure switching valve 601, the lifting drive cylinder 202, the tilting drive cylinder 302, the plate drive cylinder 402, and the leveling drive cylinder 502 through hydraulic pipelines. The control valve group 107 is provided with multiple electromagnetic control valves. According to the operation requirements, the control valve group 107 is used to control which drive cylinders are activated and which are deactivated. Generally, one electromagnetic control valve controls the operation of one drive cylinder, and one electromagnetic control valve can also control the operation of two drive cylinders. For example, the two groups of lifting drive cylinders 202 in the slide mechanism 2 are controlled by one electromagnetic control valve.

[0138] The hydraulic oil tank 108 is connected to the hydraulic pump 106, the high and low pressure switching valve 601 and the control valve group 107 through hydraulic pipelines. The hydraulic oil tank 108 is used to store hydraulic oil. The hydraulic oil delivered to the hydraulic pump 106 comes from the hydraulic oil tank 108, and the hydraulic oil flowing back from the high and low pressure switching valve 601 and the control valve group 107 flows back to the hydraulic oil tank 108.

[0139] In some possible implementations, such as Figure 8 As shown, the hydraulic mechanism 6 also includes: an external quick-change connector 605; the external quick-change connector 605 includes an external oil supply end and an external oil return end, the external oil supply end is used to deliver the external power (hydraulic equipment) to the control valve group 107, and the external oil return end is used for hydraulic oil return, and the external quick-change connector 605 is arranged on the oil circuit connecting the control valve group 107.

[0140] In some possible implementations, such as Figure 8 、 Figure 9 As shown, the high-low pressure switching valve 601 includes a valve body, a first side portion of the valve body is provided with a port A, a second side portion of the valve body is provided with ports P1, P2, and T1, and port P2 is directly connected to port A. The high-low pressure switching valve 601 further includes: a one-way valve 602, a sequence valve 603, and a relief valve 604;

[0141] The one-way valve 602 is set between the P1 port and the A port, and the flow direction is from the P1 port to the A port;

[0142] The oil inlet of the sequence valve 603 is connected to the P1 port, the oil outlet of the sequence valve 603 is connected to the T1 port, and the control port of the sequence valve 603 is connected to the A port;

[0143] The overflow valve 604 is provided between port T1 and port A;

[0144] Port A is externally connected to the control valve group 107, port P1 is externally connected to the large flow output port of the hydraulic pump 106 (the output port of the front pump), port P2 is externally connected to the small flow output port of the hydraulic pump 106 (the output port of the rear pump), and port T1 is externally connected to the hydraulic oil tank 108.

[0145] During actual operation, during the initial deployment phase of the concrete formwork system 9, the pressure from the hydraulic mechanism 6 is only needed to overcome the deadweight of the formwork unit components. At this point, the hydraulic system pressure is very low, and the pressure oil from ports P1 and P2 is supplied to port A and ultimately to the control valve assembly 107. This pressure is then supplied through the actuators (slide mechanism 2, flap mechanism 3, and insert mechanism 4) to drive the corresponding action outputs. Because the output flow from port P1 is high and the output flow from port P2 is low, the system flow is the sum of the flow from the front pump and the rear pump of hydraulic pump 106, enabling rapid deployment of the concrete formwork system 9.

[0146] During the later stages of concrete pouring formwork system 9 deployment, the actuator contacts the tunnel's inner or ceiling wall. At this point, the hydraulic system pressure gradually increases. As the contact force gradually increases, the hydraulic system pressure gradually rises, and the entire formwork unit is supported and positioned, with the actuator and the tunnel's inner or ceiling wall increasingly in contact. When the pressure exceeds a threshold, sequence valve 603 becomes conductive, and check valve 602 closes. The pressure oil at port P1 flows directly through sequence valve 603 back to port T1 of high-low pressure switching valve 601 and back to hydraulic oil tank 108. The pressure oil supply at port P2 is output through port A. The flow rate supplied to the actuator is the flow rate of the hydraulic pump 106's rear pump, which has a very low flow rate. This meets the low flow rate requirements when the actuator is deployed and in close contact with the tunnel's inner or ceiling wall. It should be noted that the high-low pressure switching valve 601 in this device can automatically adjust according to the equipment's needs, automatically switching between two pressure levels to maintain a constant force from the motor 104 or human power.

[0147] In some possible implementations, such as Figure 8 As shown, the hydraulic mechanism 6 further includes: a manual pump 105;

[0148] The manual pump 105 is connected in parallel with the hydraulic pump 106 and the high-low pressure switching valve 601. The manual pump 105 is connected to the control valve group 107 and the hydraulic oil tank 108 through hydraulic pipelines. The slide mechanism 2, the flip mechanism 3, the plug mechanism 4 and the leveling mechanism 5 can be controlled by the manual pump 105 alone.

[0149] The concrete casting formwork system 9 of the disclosed embodiment has multiple drive options, including motor drive, external power, and manual drive, to adapt to different working conditions. Users can select different power sources based on on-site construction conditions. External power drive can be used when on-site construction equipment has external power (e.g., hydraulic equipment); motor drive can be used when on-site power is readily available; and manual drive can be used when neither electricity nor a pressure source is available at the construction site.

[0150] In some possible implementations, such as Figure 1 、 Figure 2 、 Figure 3 As shown, the two groups of formwork units located on the side include a bottom platform 1, a slide mechanism 2, a flip mechanism 3 and a plug-in mechanism 4. The two groups of formwork units are symmetrically arranged on the left and right, that is, the first formwork unit 7 and the second formwork unit 8 in the figure are symmetrically arranged on the left and right.

[0151] Other formwork units can be added between the first formwork unit 7 and the second formwork unit 8 to expand the support area. The formwork unit located in the middle includes a bottom platform 1, a slide mechanism 2, and a flip mechanism 3, but does not include a plug-in mechanism 4.

[0152] It should be noted that the first mold supporting unit 7 and the second mold supporting unit 8 can share: motor 104, manual pump 105, hydraulic pump 106, high and low pressure switching valve 601 and hydraulic oil tank 108, but need to set up control valve groups 107 separately (not shared), and can also control their respective slide mechanisms 2, flip mechanisms 3, plug-in mechanisms 4, and leveling mechanisms 5.

[0153] In some possible implementations, such as Figure 1 、 Figure 3 、 Figure 6 As shown, the bottom platform 1 further includes: a ladder 101;

[0154] The ladder 101 is provided on the side of the bottom platform 1 , and the staff can climb to the top of the bottom platform 1 via the ladder 101 to operate and repair the device, and can complete the work without the assistance of climbing equipment.

[0155] In some possible implementations, such as Figure 1 、 Figure 3 、 Figure 6 As shown, the bottom platform 1 further includes: a guardrail 102;

[0156] The guardrail 102 is arranged at the rear of the bottom platform 1. The guardrail 102 can be flipped up and down. When flipped upward, it can protect the top of the bottom platform 1, thereby improving the safety of the workers during operation.

[0157] The guardrail 102 is connected to the bottom platform 1 by bolts and elastic pins. When the elastic pins are pulled out, the guardrail 102 can be flipped and folded up to 90 degrees around the fixing screws for the safety protection of the staff.

[0158] In some possible implementations, such as Figure 1 、 Figure 3 、 Figure 4 As shown, the bottom platform 1 is a box-type structure with a cover plate 103 installed at the rear. The cover plate 103 is a segmented layout form, which is connected to the main body of the bottom platform 1 by bolts and is used to protect the main components and decoration of the equipment. A double-door is provided on the cover plate 103 for device operation and maintenance.

[0159] In some possible implementations, such as Figure 1 、 Figure 6 、 Figure 7 As shown, the box-type structure of the bottom platform 1 is also equipped with components such as a tool box 109, a vacuum electromagnetic starter 110, an emergency stop switch 111 and a lighting lamp 112, among which:

[0160] The vacuum electromagnetic starter 110 adopts the QJZ-80 / 1140 model and is connected to the motor 104, the emergency stop switch 111 and the lighting lamp 112 and other electrical components. The vacuum electromagnetic starter 110 is used for system voltage supply and power management functions;

[0161] The emergency stop switch 111 can be operated from the rear of the bottom platform 1. The emergency stop switch 111 is used to shut down the power of the equipment in an emergency.

[0162] The lighting lamp 112 is arranged on the top of the bottom platform 1, and the lighting lamp 112 is used for working lighting and maintenance lighting.

[0163] The concrete casting formwork system 9 in the disclosed embodiment is deployed by a hydraulic mechanism to achieve overall positioning and support, ensuring that the formwork and the roadway are firmly connected, and then the filling material is filled in. To prevent the filling material from collapsing, a certain amount of force is provided between the concrete casting formwork system 9 and the roadway. The specific operation process is as follows:

[0164] The first step is to operate the handle of the leveling cylinder corresponding to the control valve group 107 to adjust the concrete pouring formwork system 9 to a horizontal level;

[0165] The second step is to operate the handle of the flap cylinder corresponding to the control valve group 107 to unfold the flap;

[0166] The third step is to operate the handle of the lifting cylinder corresponding to the control valve group 107 to extend the sliding plate until it reaches the top of the coal seam and reaches a certain working pressure;

[0167] The fourth step is to operate the handle of the plug-in plate oil cylinder corresponding to the control valve group 107 so that the telescopic plate can be extended and pushed to both sides of the coal seam and maintain a certain working pressure.

[0168] At this point, the concrete pouring formwork system 9 is deployed. If it needs to be retracted, the above-mentioned operation can be reversed.

[0169] The concrete pouring formwork system according to the embodiment of the present disclosure has been described above with reference to the accompanying drawings, and has the following advantages:

[0170] 1) The system consists of two or more interconnected formwork units that can be flexibly separated and installed. This modular design facilitates expansion and transportation. During operation, multiple units can be used side by side, extending steplessly to accommodate various sizes of enclosed concrete wall casting and support. After construction is complete, the units can be separated, resulting in a smaller footprint and easier transportation.

[0171] 2) The system has the characteristics of compact body and hydraulic extension. The slide plate mechanism and the plug plate mechanism can be extended and retracted steplessly, and the flip plate mechanism can also complete a maximum 90° flip to expand the support area. When the system is not deployed, the whole system can be quickly stored, which is very suitable for construction needs in narrow spaces such as underground coal mine tunnels.

[0172] 3) The system's plug-in structure adopts an elastic connection solution, which can automatically adjust the telescopic length of each plug-in according to the terrain and working conditions to complete the edge sealing.

[0173] 4) The telescopic movement of the leveling mechanism in this system can adjust the posture of the bottom platform. The system uses three leveling legs and a leveling cylinder to complete the overall adjustment work, which improves work efficiency.

[0174] 5) The system has multiple drive options, including motor drive, external power, and manual drive, to adapt to different working conditions. In addition, the high and low pressure switching valves can automatically adjust according to the needs of the equipment, realizing automatic switching between two pressure levels, so that the power of motor or human drive is constant.
