Description

Technical Field

[0001] The invention belongs to the technical field of tunnel construction, in particular to an invert and an invert filling rapid construction mechanical equipment. Background Art

[0002] The hydraulic invert trestle is composed of a front axle, a rear axle, a main axle, a front support seat, a rear running wheel frame, an automatic running device, a front support, a rear transverse mechanism, a rear running mechanism, a hydraulic automatic balancing system and an electronic control system. It can greatly improve the efficiency of tunnel invert backfill construction, meet the requirements of "early closure, early ring formation" and one-time construction length of the tunnel support system, effectively superimpose the working procedures, ensure the smooth construction of the rear of the invert section, speed up the progress and improve the safety factor of tunnel excavation.

[0003] In the prior art, when backfilling and pouring is performed through a hydraulic inverted arch trestle, the space between the interface of the hydraulic inverted arch trestle and the concrete is small. At the same time, when a high-frequency vibrator is used for vibration and compaction, the vibrator is not long enough to extend deep into the concrete, resulting in poor overall vibration quality of the concrete, which affects the backfill pouring quality of the inverted arch.

[0004] To this end, the present invention provides an inverted arch and an inverted arch filling rapid construction mechanical equipment. Summary of the invention

[0005] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0006] The technical solution adopted by the present invention to solve its technical problems is: the invention discloses a kind of inverted arch and inverted arch filling rapid construction mechanical equipment, comprising a main bridge and an inverted arch formwork; a front bridge is provided on one side of the main bridge, and a rear bridge is provided on the other side; a high-frequency vibrator and a high-frequency leveler are provided at the bottom end of the main bridge; a longitudinal sliding chute is provided on the main bridge; a pair of inverted arch formworks are arranged on both sides of the main bridge; the high-frequency vibrator comprises a first fixed plate; a longitudinal sliding track is provided at the bottom end of the main bridge; a sliding column moving on the longitudinal sliding track is slidably connected in the longitudinal sliding track; the bottom end of the sliding column is fixedly connected to the first fixed plate ; A group of first grooves are provided on the side walls on both sides of the first fixed plate; a first servo motor is fixedly connected to the side wall of the first fixed plate; the first servo motor is fixedly connected to the side wall of the first fixed plate, and a first rotating shaft is provided at the output end of the first servo motor, and the first rotating shaft passes through the first groove; a rotating plate is fixedly connected to the axis of the first rotating shaft located in the first groove; a vibrating rod is fixedly connected to the center of the side wall of the rotating plate; in the prior art, when backfilling and pouring is performed by means of a hydraulic inverted arch trestle, because the space between the interface of the hydraulic inverted arch trestle and the concrete is small, a high-frequency vibrating rod is used for vibrating and compacting at the same time. When the vibrating rod is not long enough, it cannot extend deep into the concrete, resulting in poor overall vibration quality of the concrete, affecting the backfill pouring quality of the inverted arch. For this reason, when the present invention is working, the vibrating rod of the high-frequency vibrator is placed horizontally under the main bridge, and will not affect the hydraulic inverted arch trestle when pouring or other work is carried out. The horizontally placed vibrating rod will not occupy a large horizontal space, nor will it affect other work in the vertical space. When the vibrating rod needs to be vibrated, the first servo motor is started at this time, and then the rotating plate is driven to rotate by the rotation of the first rotating shaft, and the rotating plate rotates ninety degrees. , and then place the vibrating rod vertically in the concrete that needs to be vibrated. Because the length of the horizontally placed vibrating rod will not affect the position of the vertical space, a sufficiently long vibrating rod is set to facilitate the vibrating rod to be able to extend deep into the concrete when it is in a vertical state, thereby ensuring the vibration effect and the quality of the backfill pouring of concrete. At the same time, the application of the inverted arch formwork can fully realize the curvature of the inverted arch according to the design requirements. Secondly, when the second lining trolley is closed, the second lining formwork at the arch foot position can fit perfectly with the inverted arch, without misalignment and with beautiful linearity. The longitudinal sliding chute can reduce the difficulty of chute transportation and improve the safety factor of construction.

[0007] Preferably, a pair of symmetrically distributed square tubes are fixedly connected to the side wall of the rotating plate; an extrusion spring is fixedly connected to the rotating plate, and the extrusion spring is located in the square tube, and a pressure plate is fixedly connected to the other end of the extrusion spring away from the rotating plate; the vibrating rod passes through the pressure plate; when working, the vibrating rod is inserted into the concrete for vibration and can use high-frequency vibration force to tightly combine the lower concrete and the upper concrete to avoid the occurrence of voids. However, when the vibrating rod is used for vibration, the vibration force and the gravity and flow force of the concrete itself are used for tight compaction, and the compaction flow is relatively slow. Therefore, in order to further increase the tight compaction effect, a pressure plate is provided on the rotating plate, and the pressure plate is fixed to the rotating plate through the extrusion spring. When the rotating plate rotates from a vertical state to a horizontal state, the pressure plate will be tightly attached to the concrete interface under the action of the spring force of the extrusion spring. When the vibrating rod is vibrated, the pressure plate will be pressed downward under the action of the spring force of the extrusion spring, which can facilitate the vibration of the vibrating rod, increase the compaction force on the concrete, and further save the vibration time.

[0008] Preferably, the pressing plate includes a flat plate and an arc plate; the extrusion spring is fixedly connected to the flat plate, and the vibrating rod passes through the flat plate; arc plates are fixedly connected to the side walls of the flat plate on both sides; during operation, since the pressing plate rotates along with the rotating plate, in order to avoid the two sides of the pressing plate shoveling concrete when the pressing plate rotates, thereby affecting the plane integrity of the concrete, and also to avoid the concrete splashing due to the rotation of the pressing plate, the pressing plate is set to be a flat plate and an arc plate. When the pressing plate rotates, the arc plate will first contact the concrete interface, and then push the pressing plate as a whole toward the rotating plate, which can effectively avoid the concrete surface being shoveled away. At the same time, the setting of the arc plate is also convenient for pushing on the concrete surface, avoiding the horizontal shoveling of the concrete when the pressing plate moves horizontally, and also avoiding the concrete moving to the top of the pressing plate, which is inconvenient to clean.

[0009] Preferably, a fixing block is fixedly connected to the middle part of the extrusion spring; the fixing block is slidably connected to the inner wall of the square tube; a pair of symmetrically distributed first inclined surfaces are provided on the side wall of the fixing block close to the rotating plate; second grooves are provided on the inner walls of both sides of the square tube; a blocking block is fixedly connected to the second groove through a spring, and the end cross-section of the blocking block is a right-angled trapezoid; the first inclined surface and the trapezoidal inclined surface of the blocking block are parallel to each other; during operation, in order to facilitate the rotation of the pressing plate with the rotating plate and avoid shoveling between the pressing plate and concrete, it is only necessary to reduce the distance between the pressing plate and the rotating plate, which can reduce the rotation radius of the pressing plate and thus avoid To prevent the pressure plate from contacting the concrete when it rotates, a fixed block is provided. Since the fixed block is arranged in the middle of the extrusion spring, when the pressure plate is pushed in the direction of the rotating plate, the extrusion spring will be squeezed, thereby pushing the pressure plate to move in the direction of the rotating plate, thereby reducing the distance between the rotating plate and the pressure plate. The fixed block will move on the inner wall of the square cylinder, and the locking block will be pushed into the second groove through the mutual push of the first inclined surface and the trapezoidal inclined surface of the locking block. Then, when the fixed block and the locking block are misaligned, the locking block will rebound under the action of the spring force to block the movement of the fixed block, thereby locking the fixed block to ensure the distance between the pressure plate and the rotating plate, which is convenient for the pressure plate to rotate with the rotating plate.

[0010] Preferably, a first magnetic layer is fixedly connected to the side wall of the positioning block; an electromagnetic layer is fixedly connected to the bottom of the second groove; when the electromagnetic layer is energized, the electromagnetic layer and the first magnetic layer attract each other; during operation, when the rotating plate rotates to a horizontal position, the rotating plate is required to contact and extrude the concrete interface, and at this time, by energizing the electromagnetic layer, the electromagnetic layer and the first magnetic layer are mutually attracted, so that the positioning block moves into the second groove, and then the fixed block moves outward under the action of the extrusion force of the extrusion spring, so that the rotating plate and the concrete interface are in contact with each other, thereby completing the extrusion of the concrete to be vibrated.

[0011] Preferably, a pair of symmetrically distributed second servo motors are fixedly connected to the rotating plate; a second rotating shaft is provided at the output end of the second servo motor; a winding wheel is provided on the second rotating shaft; the winding wheel is connected to the pressure plate through a first thin rope; during operation, after the pressure plate finishes working, the second servo motor is started to drive the winding wheel to rotate, and the rotation of the winding wheel will pull and move the pressure plate through the first thin rope, thereby facilitating the retraction of the pressure plate, and there is no need to manually pull the pressure plate to move.

[0012] Preferably, a hollow groove is provided in the middle of the winding wheel; an annular T-shaped groove is provided on the outer side wall of the winding wheel; a T-shaped column is fixedly connected to the side wall of the rotating plate; the end of the T-shaped column is slidably connected to the annular T-shaped groove; the second rotating shaft is located in the hollow groove; a pair of symmetrically distributed third grooves are provided on the outer side wall of the second rotating shaft; a positioning block is fixedly connected to the bottom of the third groove through a spring; a pair of symmetrically distributed arc grooves are provided on the inner wall of the hollow groove; the arc groove and the third groove are on the same vertical plane; during operation, when the second servo motor is rotating, the positioning block will be stuck in the arc groove under the action of centrifugal force, thereby driving the rotation of the winding wheel, and then through the third A thin rope pulls the rotating plate to move, but when the fixed block is not stuck in the positioning block, the second servo motor stops at this time, and the positioning block will enter the third groove under the action of the spring force, and then the pressure plate will move downward under the action of the extrusion spring force. Under the action of the second servo motor and the extrusion spring, the pressure plate can be moved back and forth on the concrete interface, further increasing the extrusion and enhancement effect on the concrete. At the same time, when the second servo motor rotates for too long and the fixed block is stuck in place by the positioning block, the pressure plate can be conveniently limited at this time. Since the servo motor can accurately rotate the number of circles and the speed, the above-mentioned principle operation can be realized. At the same time, due to the setting of the arc plate, the pressure plate can be prevented from being pressed into the concrete.

[0013] Preferably, a fourth groove is provided on the curved surface of the curved plate; a rolling roller is provided in the fourth groove; the rolling roller is rotated by a motor, and the outer wall of the rolling roller extending out of the fourth groove and the side wall of the flat plate are in the same plane; during operation, because there are some crushed stones on the surface of the concrete, when the pressing plate is on a horizontal plane, the motor is started to drive the rolling roller to rotate, and when the rotating plate rotates in the horizontal direction, the rotation of the rolling roller can be used to squeeze some crushed stones on the surface of the concrete into the interior of the concrete, and at the same time, the curved surface of the curved plate can squeeze some larger crushed stones. Through the setting of the rolling roller, the crushed stones can be easily squeezed into the interior of the concrete, and the impact on the flat plate is also avoided.

[0014] Preferably, the rolling roller is provided with a group of annular grooves; a group of first arc blocks are fixedly connected to the inner wall of the annular groove; a first cavity is provided in the plane plate; a group of movable plates are slidably connected in the first cavity; a group of movable plates are mutually connected by elastic sheets; a group of movable plates are fixedly connected to a push rod at one end, and the push rod extends into the annular groove and is fixedly connected to a second arc block, and the other end of a group of movable plates is fixedly connected to the side wall of the first cavity through a fixed column; the elastic sheet is arranged in an arc shape, and the inner curved surface of the elastic sheet is fixedly connected to a vibration ball through a connecting rod; when working, when the pressing plate and the concrete surface are squeezed up and down, the concrete surface is The concrete surface is in a solid-liquid state. At this time, when the pressure plate and concrete are directly attached to each other, the two have a certain adsorption force. In order to avoid affecting the up and down movement state and the horizontal movement state of the pressure plate, a first cavity is provided in the plane plate of the pressure plate. When the rolling roller rotates, the second arc block will be pushed to move by the first arc block, thereby squeezing the elastic sheets between a group of moving plates, and then letting the vibration ball move away from the side wall of the first cavity. When the moving plate rebounds under the action of the elastic sheet, it will collide with the side wall of the first cavity through the vibration ball, thereby increasing the vibration force on the pressure plate, which is convenient for the pressure plate and the concrete interface to separate from each other.

[0015] Preferably, the vibration ball is made of rubber. When working, the vibration ball is made of rubber material, which can ensure the vibration intensity while avoiding damage to the rigid collision inside the pressure plate.

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. The invention discloses a kind of inverted arch and inverted arch filling rapid construction machinery and equipment. Because the length of the horizontally placed vibrating rod will not affect the position of the vertical space, a sufficiently long vibrating rod is provided so that when the vibrating rod is in a vertical state, it can be extended into a position deep in the concrete to ensure the vibration effect and the backfill pouring quality of the concrete. At the same time, the application of the inverted arch arc formwork can realize the curvature of the inverted arch in full accordance with the design requirements. Secondly, when the second lining trolley is molded, the second lining formwork at the arch foot position can perfectly fit with the inverted arch, so as to achieve no misalignment and beautiful linear appearance. The longitudinal sliding chute can reduce the difficulty of chute transportation and improve the construction safety factor.

[0018] 2. The rapid construction mechanical equipment of an inverted arch and inverted arch filling described in the present invention, when the second servo motor is rotating, the positioning block will be stuck in the arc groove under the action of centrifugal force, thereby driving the rotation of the winding wheel, and then the rotating plate is moved by pulling the first thin rope, but when the fixed block is not stuck by the positioning block, the second servo motor is stopped at this time, and the positioning block will enter the third groove under the action of the spring force, and then the pressure plate will move downward under the action of the extrusion spring force, and under the action of the second servo motor and the extrusion spring, the pressure plate can be moved back and forth on the concrete interface, further increasing the extrusion and enhancement effect on the concrete.

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0030] Embodiment 1

[0031] like Figures 1 to 3 As shown, an inverted arch and inverted arch filling rapid construction mechanical equipment according to an embodiment of the present invention comprises a main bridge 1 and an inverted arch formwork 16; a front bridge 11 is provided on one side of the main bridge 1, and a rear bridge 12 is provided on the other side; a high-frequency vibrator 13 and a high-frequency leveler 14 are provided at the bottom end of the main bridge 1; a longitudinal sliding chute 15 is provided on the main bridge 1; a pair of the inverted arch formwork 16 are arranged on both sides of the main bridge 1; the high-frequency vibrator 13 comprises a first fixed plate 21; a longitudinal sliding track is provided at the bottom end of the main bridge 1; a sliding column 2 moving on the longitudinal sliding track is slidably connected in the longitudinal sliding track; the bottom end of the sliding column 2 is fixedly connected to the first fixed plate 21; the first A group of first grooves 24 are provided on the side walls of both sides of the fixed plate 21; a first servo motor 22 is fixedly connected to the side wall of the first fixed plate 21; the first servo motor 22 is fixedly connected to the side wall of the first fixed plate 21, and a first rotating shaft 23 is provided at the output end of the first servo motor 22, and the first rotating shaft 23 passes through the first groove 24; a rotating plate 25 is fixedly connected to the axis of the first rotating shaft 23 located in the first groove 24; a vibrating rod 26 is fixedly connected to the center of the side wall of the rotating plate 25; in the prior art, when backfilling and pouring is performed by a hydraulic inverted arch trestle, because the space between the interface of the hydraulic inverted arch trestle and the concrete is small, and at the same time, when using the high-frequency vibrating rod 2 When vibrating and compacting, the vibrating rod 26 cannot be inserted into the deep concrete due to the insufficient length of the vibrating rod 26, resulting in poor overall vibration quality of the concrete and affecting the backfill pouring quality of the inverted arch. For this reason, when the present invention is working, the vibrating rod 26 of the high-frequency vibrator 13 is horizontally placed under the main bridge 1, and will not affect the hydraulic inverted arch trestle when pouring or other work is performed. The horizontally placed vibrating rod 26 will not occupy a large horizontal space, nor will it affect other work in the vertical space. When the vibrating rod 26 needs to be vibrated, the first servo motor 22 is started, and then the rotating plate 25 is driven to rotate by the first rotating shaft 23, and the rotating plate 25 is rotated ninety degrees, and then the vibrating rod 26 is vertically placed in the concrete that needs to be vibrated. Because the length of the horizontally placed vibrating rod 26 will not affect the position of the vertical space, a sufficiently long vibrating rod 26 is set to facilitate the vibrating rod 26 to be able to extend into the deep position of the concrete when it is in a vertical state, thereby ensuring the vibration effect and the backfill pouring quality of the concrete. At the same time, the application of the inverted arch formwork 16 can fully realize the inverted arch curvature according to the design requirements. Secondly, when the second lining trolley is molded, the second lining formwork at the arch foot position can perfectly fit with the inverted arch, so as to achieve no misalignment and beautiful linearity. The longitudinal sliding chute 15 can reduce the difficulty of chute transportation and improve the construction safety factor.

[0032] like Figures 3 to 6As shown, a pair of symmetrically distributed square tubes 31 are fixedly connected to the side wall of the rotating plate 25; an extrusion spring 32 is fixedly connected to the rotating plate 25, and the extrusion spring 32 is located in the square tube 31, and the other end of the extrusion spring 32 away from the rotating plate 25 is fixedly connected to the pressing plate 3; the vibrating rod 26 passes through the pressing plate 3; when working, the vibrating rod 26 is inserted into the concrete for vibration, and can use high-frequency vibration force to tightly combine the lower layer of concrete and the upper layer of concrete to avoid the occurrence of voids, but because when the vibrating rod 26 is used for vibration, the vibration force and the gravity and flow force of the concrete itself are used for compaction. The compaction flow is relatively slow. In order to further increase the compaction effect, a pressure plate 3 is provided on the rotating plate 25, and the pressure plate 3 is fixed to the rotating plate 25 by an extrusion spring 32. When the rotating plate 25 rotates from a vertical state to a horizontal state, the pressure plate 3 will fit tightly on the concrete interface under the action of the spring force of the extrusion spring 32. When the vibrating rod 26 is vibrated, the pressure plate 3 will be pressed downward under the action of the spring force of the extrusion spring 32, which can facilitate the vibration of the vibrating rod 26, increase the compaction force on the concrete, and further save the vibration time.

[0033] The pressing plate 3 includes a flat plate 33 and an arc plate 34; the extrusion spring 32 is fixedly connected to the flat plate 33, and the vibrating rod 26 passes through the flat plate 33; the side walls of the flat plate 33 are fixedly connected with arc plates 34; during operation, since the pressing plate 3 rotates along with the rotating plate 25, in order to avoid the pressing plate 3 rotating, the two sides of the pressing plate 3 will shovel the concrete, thereby affecting the integrity of the plane of the concrete, and also avoid the concrete splashing due to the rotation of the pressing plate 3, the pressing plate 3 is set to be a flat plate 33 and an arc plate 34. When the pressing plate 3 rotates, the arc plate 34 will first contact the concrete interface, and then push the pressing plate 3 as a whole toward the rotating plate 25, which can effectively avoid the concrete surface from being shoveled away. At the same time, the setting of the arc plate 34 is also convenient for pushing on the concrete surface, avoiding the concrete from being horizontally shoveled when the pressing plate 3 moves horizontally, and also avoiding the concrete from moving to the top of the pressing plate 3, which is inconvenient to clean.

[0034] A fixing block 35 is fixedly connected to the middle part of the extrusion spring 32; the fixing block 35 is slidably connected to the inner wall of the square tube 31; a pair of symmetrically distributed first inclined surfaces 36 are provided on the side wall of the fixing block 35 close to the rotating plate 25; second grooves 37 are provided on the inner walls of both sides of the square tube 31; the second groove 37 is fixedly connected to a blocking block 38 through a spring, and the end section of the blocking block 38 is a right-angled trapezoid; the first inclined surface 36 and the trapezoidal inclined surface of the blocking block 38 are parallel to each other; during operation, in order to facilitate the rotation of the pressing plate 3 with the rotating plate 25 and avoid the shoveling between the pressing plate 3 and the concrete, it is only necessary to reduce the distance between the pressing plate 3 and the rotating plate 25, which can reduce the rotation radius of the pressing plate 3, thereby avoiding the pressing plate 3 from rotating. The contact between the fixing block 35 and the concrete is provided. Because the fixing block 35 is arranged in the middle of the extrusion spring 32, when the pressing plate 3 is pushed in the direction of the rotating plate 25, the extrusion spring 32 will be squeezed, thereby pushing the pressing plate 3 to move in the direction of the rotating plate 25, thereby reducing the distance between the rotating plate 25 and the pressing plate 3, and the fixing block 35 will move on the inner wall of the square tube 31, and the first inclined surface 36 and the trapezoidal inclined surface of the blocking block 38 will push the blocking block 38 into the second groove 37, and then when the fixing block 35 and the blocking block 38 are misaligned, the blocking block 38 will rebound under the action of the spring force, blocking the movement of the fixing block 35, and then blocking the fixing block 35, ensuring the distance between the pressing plate 3 and the rotating plate 25, and facilitating the rotation of the pressing plate 3 with the rotating plate 25.

[0035] A first magnetic layer 4 is fixedly connected to the side wall of the positioning block 38; an electromagnetic layer 41 is fixedly connected to the bottom of the second groove 37; when the electromagnetic layer 41 is energized, the electromagnetic layer 41 and the first magnetic layer 4 attract each other; during operation, when the rotating plate 25 rotates to a horizontal position, the rotating plate 25 is required to contact and extrude the concrete interface. At this time, by energizing the electromagnetic layer 41, the electromagnetic layer 41 and the first magnetic layer 4 are mutually adsorbed, so that the positioning block 38 moves into the second groove 37, and then the fixed block 35 moves outward under the action of the extrusion force of the extrusion spring 32, so that the rotating plate 25 and the concrete interface are in contact with each other, thereby completing the extrusion of the concrete to be vibrated.

[0036] A pair of symmetrically distributed second servo motors 42 are fixedly connected to the rotating plate 25; a second rotating shaft 43 is provided at the output end of the second servo motor 42; a winding wheel 44 is provided on the second rotating shaft 43; the winding wheel 44 is connected to the pressure plate 3 through a first thin rope 45; during operation, after the pressure plate 3 finishes working, the second servo motor 42 is started to drive the winding wheel 44 to rotate, and the rotation of the winding wheel 44 will pull and move the pressure plate 3 through the first thin rope 45, thereby facilitating the retraction of the pressure plate 3, and there is no need to manually pull the pressure plate 3 to move.

[0037] A hollow groove is provided in the middle of the winding wheel 44; an annular T-shaped groove 5 is provided on the outer side wall of the winding wheel 44; a T-shaped column 51 is fixedly connected to the side wall of the rotating plate 25; the end of the T-shaped column 51 is slidably connected to the annular T-shaped groove 5; the second rotating shaft 43 is located in the hollow groove; a pair of symmetrically distributed third grooves 46 are provided on the outer side wall of the second rotating shaft 43; a positioning block 47 is fixedly connected to the bottom of the third groove 46 through a spring; a pair of symmetrically distributed arc grooves 48 are provided on the inner wall of the hollow groove; the arc groove 48 and the third groove 46 are on the same vertical plane; during operation, when the second servo motor 42 is rotating, the positioning block 47 will be stuck in the arc groove 48 under the action of centrifugal force, thereby driving the rotation of the winding wheel 44, and then through the third servo motor 42 ... A thin rope 45 pulls the rotating plate 25 to move, but when the fixed block 35 is not engaged by the locking block 38, the second servo motor 42 stops at this time, and the positioning block 47 is acted upon by the spring force to enter the third groove 46, and then the pressing plate 3 moves downward under the action of the extrusion spring 32. Under the action of the second servo motor 42 and the extrusion spring 32, the pressing plate 3 can be moved back and forth on the concrete interface, further increasing the extrusion and enhancement effect on the concrete. At the same time, when the second servo motor 42 rotates for too long and the fixed block 35 is engaged by the locking block 38, the pressing plate 3 can be conveniently limited at this time. Since the servo motor can accurately rotate the number of circles and the speed, the above-mentioned principle operation can be realized. At the same time, due to the setting of the arc plate 34, the pressing plate 3 can be prevented from being pressed into the concrete.

[0038] A fourth groove 52 is provided on the arc surface of the arc plate 34; a rolling roller 53 is provided in the fourth groove 52; the rolling roller 53 is rotated by a motor, and the outer side wall of the rolling roller 53 extending out of the fourth groove 52 and the side wall of the flat plate 33 are in the same plane; during operation, because there are some crushed stones on the surface of the concrete, when the pressing plate 3 is on a horizontal plane, the motor is started to drive the rolling roller 53 to rotate, and when the rotating plate 25 rotates in the horizontal direction, the rotation of the rolling roller 53 can be used to squeeze some crushed stones on the surface of the concrete into the concrete, and at the same time, the arc surface of the arc plate 34 can squeeze some larger crushed stones. Through the setting of the rolling roller 53, the crushed stones can be easily squeezed into the concrete, and the impact on the flat plate 33 is also avoided.

[0040] like Figures 7 and 8As shown, compared with Example 1, another embodiment of the present invention is as follows: a group of annular grooves 54 are provided on the rolling roller 53; a group of first arc blocks 55 are fixedly connected to the inner wall of the annular groove 54; a first cavity 57 is provided in the plane plate 33; a group of movable plates 58 are slidably connected in the first cavity 57; a group of movable plates 58 are mutually connected by elastic sheets 59; a group of movable plates 58 are fixedly connected to a push rod 56 at one end of a group of movable plates 58, and the push rod 56 extends into the annular groove 54 and is fixedly connected to a second arc block 551, and the other end of a group of movable plates 58 is fixedly connected to the side wall of the first cavity 57 through a fixing column; the elastic sheet 59 is arranged in an arc shape, and the inner curved surface of the elastic sheet 59 is fixedly connected to a vibration ball 591 through a connecting rod; when working, under the pressure When the plate 3 and the concrete surface are squeezed up and down, because the concrete surface is in a solid-liquid state, when the pressing plate 3 and the concrete are directly attached to each other, the two have a certain adsorption force. In order to avoid affecting the up and down movement state and the horizontal movement state of the pressing plate 3, a first cavity 57 is provided in the plane plate 33 of the pressing plate 3. When the rolling roller 53 rotates, the second arc block 551 is pushed to move by the first arc block 55, so that the elastic sheet 59 between a group of moving plates 58 is squeezed, and then the vibration ball 591 is moved away from the side wall of the first cavity 57. When the moving plate 58 rebounds under the action of the elastic sheet 59, it will collide with the side wall of the first cavity 57 through the vibration ball 591, thereby increasing the vibration force on the pressing plate 3, which is convenient for the pressing plate 3 and the concrete interface to separate from each other.

[0041] The material of the vibration ball 591 is rubber. When working, the vibration ball 591 is made of rubber, which can ensure the vibration intensity while avoiding damage to the rigid collision inside the pressure plate 3.

[0042] Working principle: When backfilling and pouring is performed through the hydraulic inverted arch trestle, the space between the interface of the hydraulic inverted arch trestle and the concrete is small. At the same time, when the high-frequency vibrator 26 is used for vibrating and compacting, the vibrator 26 cannot be inserted into the deep concrete due to the insufficient length of the vibrator 26, resulting in poor overall vibration quality of the concrete, affecting the backfilling and pouring quality of the inverted arch. For this reason, when the present invention is working, the vibrator 26 of the high-frequency vibrator 13 is horizontally placed under the main bridge 1, and will not affect the hydraulic inverted arch trestle when pouring or other work is performed. The horizontally placed vibrator 26 will not occupy a large horizontal space, nor will it affect other work in the vertical space. When the vibrator 26 is needed to vibrate During tamping, the first servo motor 22 is started, and the first rotating shaft 23 is then used to drive the rotating plate 25 to rotate. The rotating plate 25 rotates ninety degrees, and the vibrating rod 26 is vertically placed in the concrete to be vibrated. Because the length of the horizontally placed vibrating rod 26 will not affect the position of the vertical space, a sufficiently long vibrating rod 26 is provided to facilitate the vibrating rod 26 to be able to extend into a position deep in the concrete when it is in a vertical state, thereby ensuring the vibrating effect and the quality of the backfilling and pouring of the concrete; when the vibrating rod 26 is extended into the concrete for vibrating, the high-frequency vibration force can be used to tightly combine the lower concrete and the upper concrete to avoid the occurrence of voids. However, when the vibrating rod 26 is used for vibrating, vibration is used. The compaction flow is relatively slow, and in order to further increase the compaction effect, a pressing plate 3 is provided on the rotating plate 25, and the pressing plate 3 is fixed to the rotating plate 25 by a squeezing spring 32. When the rotating plate 25 rotates from a vertical state to a horizontal state, the pressing plate 3 will be tightly attached to the concrete interface under the action of the spring force of the squeezing spring 32. When the vibrating rod 26 is vibrated, the pressing plate 3 will be pressed downward under the action of the spring force of the squeezing spring 32, which can facilitate the vibrating rod 26 to vibrate, increase the compaction force on the concrete, and further save the vibration time. Because the pressing plate 3 follows the rotating plate 25 In order to prevent the two sides of the pressing plate 3 from shoveling the concrete when the pressing plate 3 rotates, thereby affecting the integrity of the plane of the concrete and preventing the concrete from splashing due to the rotation of the pressing plate 3, the pressing plate 3 is configured as a flat plate 33 and an arc plate 34. When the pressing plate 3 rotates, the arc plate 34 will first contact the concrete interface, and then push the pressing plate 3 as a whole toward the rotating plate 25, which can effectively prevent the concrete surface from being shoveled away. At the same time, the setting of the arc plate 34 is also convenient for pushing on the concrete surface, avoiding the horizontal shoveling of the concrete when the pressing plate 3 moves horizontally, and also preventing the concrete from moving above the pressing plate 3, which is inconvenient to clean;The cam 35 is provided with a fixing block 35, because the fixing block 35 is arranged in the middle of the extrusion spring 32, when the pressing plate 3 is pushed in the direction of the rotating plate 25, the extrusion spring 32 will be squeezed, thereby pushing the pressing plate 3 to move in the direction of the rotating plate 25, thereby reducing the distance between the rotating plate 25 and the pressing plate 3, and the fixing block 35 will move on the inner wall of the square cylinder 31, and the first inclined surface 36 and the trapezoidal inclined surface of the blocking block 38 will push the blocking block 38 into the second groove 37, and then when the fixing block 35 and the blocking block 38 are misaligned, the blocking block 38 will rebound under the action of the spring force, blocking the movement of the fixing block 35, thereby blocking the fixing block 35, ensuring the distance between the pressing plate 3 and the rotating plate 25, and facilitating the pressing The plate 3 rotates with the rotating plate 25; when the second servo motor 42 is rotating, the positioning block 47 will be stuck in the arc groove 48 under the action of centrifugal force, thereby driving the rotation of the winding wheel 44, and then the rotating plate 25 is pulled to move by the first thin rope 45. However, when the fixed block 35 is not stuck in the blocking block 38, the second servo motor 42 is stopped at this time, and the positioning block 47 will enter the third groove 46 under the action of the spring force, and then the pressing plate 3 will move downward under the action of the extrusion spring 32. Under the action of the second servo motor 42 and the extrusion spring 32, the pressing plate 3 can be moved back and forth on the concrete interface, further increasing the extrusion and enhancement effect of the concrete. At the same time, when the second servo motor 42 rotates for too long and the fixed block 35 is blocked by the blocking block 38, the pressing plate 3 can be conveniently limited at this time. Because the servo motor can accurately rotate the number of circles and the speed, the above-mentioned principle operation can be realized. At the same time, due to the setting of the arc plate 34, the pressing plate 3 can be prevented from being pressed into the concrete. ;
