Description

Technical Field

[0001] This invention belongs to the field of tunnel engineering construction, and specifically relates to an automatic pouring device. Background Technology

[0002] A tunnel invert arch is a reverse arch structure set at the bottom of a tunnel to improve the stress conditions of the superstructure. It is one of the main components of a tunnel structure and is generally explained as an arch that tilts upwards.

[0003] Traditional invert arch construction utilizes invert arch trestle bridges equipped with invert arch formwork. These trestle bridges come in various forms, including simple, hydraulically operated, and cantilevered types. Regardless of the type, existing invert arch trestle bridges differ only in the invert arch excavation and trestle bridge movement; the concrete pouring method is essentially the same: concrete mixer trucks move back and forth on the trestle bridge, and the chute is manually adjusted for pouring. This method makes it difficult to guarantee the quality of the pouring. Furthermore, the pouring of the invert arch and filling concrete must yield to tunnel excavation and support construction. This is because invert arch concrete pouring does not occur during tunnel muck removal or shotcrete application; parking the mixer trucks on the trestle bridge would obstruct its passage, further complicating construction organization. Summary of the Invention

[0004] In view of this, the present invention provides an automatic pouring device with a symmetrically arranged discharge mechanism and a material placing mechanism that can rotate 360° in a vertical plane. This allows it to adapt to the all-round symmetrical layered pouring of the invert arch, and the material placing is convenient and flexible, effectively resolving construction conflicts and saving manpower and resources. It solves the technical problems of inflexibility and high construction organization difficulty in existing tunnel invert arch pouring methods.

One end of the wire rope is connected to the first ear plate, and the other end is connected to the second ear plate through a tensioner.

[0041] The automatic pouring device of this invention is used for the pouring of tunnel inverts. Compared with the traditional method of pouring invert concrete, its biggest feature is that the passage of the trestle can be continued during the pouring of the invert short sidewalls, which reduces the difficulty of tunnel construction organization. During the pouring of the invert, the concrete transport truck stops outside the trestle to supply mortar to the power pump, and the material is discharged through the automatic pouring device, which no longer occupies the passage of the trestle. Thus, the pouring can be carried out at the same time without hindering the passage of the trestle.

[0042] The automatic pouring device provided by this invention can achieve symmetrical pouring because the discharge mechanism is symmetrically arranged on both sides of the walking mechanism. Furthermore, since the discharge port of the discharge mechanism can rotate in the horizontal plane, it can achieve full coverage of the invert arch concrete pouring working surface, which facilitates concrete vibration and improves the quality of invert arch concrete pouring.

[0043] The automatic pouring device provided by this invention has a concrete placing machine that can rotate 360° in the vertical plane. Both the concrete placing machine and the discharge mechanism can move back and forth with the walking mechanism, and the discharge port of the discharge mechanism can rotate in the horizontal plane, ensuring that the discharge range can cover the entire inverted arch pouring surface. Only one person needs to operate the control panel to realize the automatic material placement during the pouring process, which effectively saves manpower and can significantly reduce the labor intensity of the workers.

Detailed Implementation

[0059] To facilitate understanding of the present invention, a more comprehensive description will be given below with reference to specific embodiments. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of the present invention.

[0060] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0061] An embodiment of the present invention discloses an automatic pouring device for tunnel invert arches, which includes a feeding mechanism 10, a traveling mechanism 20, a material placing mechanism 30, and a material discharging mechanism 40.

[0062] Feeding mechanism 10 Figure 1 and Figure 6As shown, its feed end is connected to a power pump, and the feeding mechanism 10 has a telescopic folding arm structure. The power pump here refers to a ground pump or truck pump, etc., mainly used to transport materials into the automatic pouring device. Specifically, the feeding mechanism 10 includes a first horizontal pipe 101, a first vertical pipe 111, a second horizontal pipe 102, a second vertical pipe 112, and a third horizontal pipe 103, as shown... Figure 6 and Figure 1 As shown, the first horizontal pipe 101 is fixed to the side wall of the main beam of the arch bridge. Its fixing method can adopt conventional pump pipe fixing methods in this field. In this embodiment, the specific fixing method is to fix several pump pipe fixing seats (using conventional fixing methods such as welding, riveting, threaded connection, and casting) on ​​the side wall of the main beam of the arch bridge. In this embodiment, these are U-shaped fixing grooves. The first horizontal pipe 101 is embedded in the U-shaped fixing groove, and then the first horizontal pipe 101 is fixed using U-shaped pipe clamps. The U-shaped pipe clamps and the U-shaped fixing grooves can use conventional connection methods such as threaded connection, which will not be elaborated here. The number of U-shaped fixing grooves can be adjusted as needed, so it is not specifically limited here. Furthermore, as... Figure 1 and Figure 6 As shown, one end of the first horizontal pipe 101 is connected to the power pump, and its end away from the power pump is connected to the first vertical pipe 111, and as... Figure 6 As shown, the first horizontal tube 101 and the first vertical tube 111 are connected by an elbow, which refers to a regular elbow. The end of the first vertical tube 111 away from the first horizontal tube 101 is connected to the second horizontal tube 102 through a movable elbow, and the second horizontal tube 102 is perpendicular to the first horizontal tube 101. The end of the second horizontal tube 102 away from the first vertical tube 111 is connected to the second vertical tube 112 through a movable elbow. The end of the second vertical tube 112 away from the second horizontal tube 102 is connected to the third horizontal tube 103 through a movable elbow. The end of the third horizontal tube 103 away from the second vertical tube 112 is connected to the traveling mechanism 20 through a movable elbow. Because multiple movable elbows are used for connection, a folding arm structure can be formed. The pipeline of the feeding mechanism 10 can be extended or folded as the traveling mechanism 20 moves forward or backward.

[0063] For further information, please refer to [link / reference]. Figure 6To ensure the stability of the feeding mechanism 10 during extension or folding, in this embodiment, a first bearing 121 and a first pipe clamp 131 are sequentially fitted onto the first vertical tube 111. The first pipe clamp 131 is mainly used to prevent the first bearing 121 from slipping off. A second pipe clamp 132 is fitted onto the first bearing 121. In addition, a third pipe clamp 133 is fitted onto the second horizontal tube 102. A first pull rod 141 is connected between the second pipe clamp 132 and the third pipe clamp 133. Furthermore, a fourth pipe clamp 134 is fitted onto the third horizontal tube 103. A second pull rod 142 is connected between the fourth pipe clamp 134 and the traveling mechanism 20. 41 and the second pull rod 142 can stabilize the pipeline of the feeding mechanism 10 and ensure stability during the extension or folding process. It is understood that the first pipe clamp 131, the second pipe clamp 132, the third pipe clamp 133 and the fourth pipe clamp 134 here are all conventional pipe clamps in the art, such as double-ear plate U-shaped pipe clamps. The first pull rod 141 and the second pull rod 142 are both telescopic pull rod structures. In this embodiment, they are all pull rods with single ears at both ends. The connection method between them and the pipe clamp adopts conventional connection protection in the art. Specifically, in this embodiment, the first pull rod 141 and the second pull rod 142 are connected to the corresponding pipe clamp at the joint with rivets.

[0064] Walking mechanism 20, such as Figure 1 and Figure 7 As shown, it includes a traveling section and a drive section. Specifically, the traveling section includes a track beam 211, traveling wheels 212, a continuous slot 213, and a rack 214. Please refer to the following: Figure 7 In this embodiment, the upper end face of the track beam 211 is fixed to the underside of the arch bridge. The fixing method used is conventional in the art, such as welding, riveting, or threaded connection. In this embodiment, the upper end face of the track beam 211 is fixed to the underside of the arch bridge by welding. Furthermore, the track beam 211 has a hollow internal structure, with the traveling wheels 212 placed inside and moving along the track beam 211. Specifically, a continuous groove 213 is located at the center line of the opposite surface of the track beam 211 and the fixed surface of the arch bridge. The traveling wheels 212 consist of two sets of four rubber guide wheels 215, connected by axles 216, so that each traveling wheel has two rubber guide wheels 215 on each side and moves along the side wall of the track beam 211. The side wall on which the traveling wheels 212 move is on the same side as the continuous groove 213. Furthermore, two sets of racks 214 are arranged parallel to each other on the outer side of the track beam 211 where the continuous groove 213 is located. Furthermore, the drive unit includes a first housing 201 and a second housing 202. Please refer to the following: Figure 7A connecting rod 217 is fixedly mounted on the axle 216 of the rubber guide wheel 215. The connecting rod 217 passes through the through slot 213 and connects to the first housing 201 and the second housing 202. In this embodiment, there are three traveling wheels 212. The connecting rods 217 connected to two axles 216 are fixedly connected to the first housing 201, and the connecting rod 217 connected to the other axle 216 is fixedly connected to the second housing 202. In this embodiment, welding is used. It is understood that other fixing methods commonly used in the art can also be applied. Specifically, on the side of the first housing 201 facing the feeding mechanism 10, there are fixed hinge seats for fixing the end of the second pull rod 142 and elbows for connecting to the movable elbows of the third horizontal tube 103. A drive motor is provided inside the first housing 201. The output end of the drive motor is provided with two sets of drive gears 203. The drive gears 203 extend out of the first housing 201 and mesh with the rack 214.

[0065] Please continue reading. Figure 7 The fabric-laying mechanism 30 rotates between the first housing 201 and the second housing 202, and is connected to the first housing 201. Specifically, a pipe passes through the first housing 201, thereby connecting with the fabric-laying mechanism 30. The fabric-laying mechanism 30 is provided with a discharge port 301, which can rotate 360° in the vertical plane. That is to say, the fabric-laying mechanism 30 mainly rotates in the vertical plane under the support of the first housing 201 and the second housing 202. Preferably, a motor is provided in the second housing 202, and the motor is connected to the fabric-laying mechanism 30 to drive the fabric-laying mechanism 30 to rotate.

[0066] Discharge mechanism 40, such as Figure 8 , Figure 2 , Figure 3 and Figure 4 As shown, they are symmetrically arranged on both sides of the traveling mechanism 20, thereby enabling symmetrical casting of the tunnel invert surface. Specifically, as... Figure 8 As shown, the discharge mechanism 40 includes a fourth horizontal tube 104, a third vertical tube 113, a fifth horizontal tube 105, and a discharge hose 401. One end of the fourth horizontal tube 104 is connected to the discharge port 301. In this embodiment, the connection end between the fourth horizontal tube 104 and the discharge port 301 is a flared structure for easy feeding. The end of the fourth horizontal tube 104 away from the discharge port 301 is connected to the third vertical tube 113 via an elbow. The end of the third vertical tube 113 away from the fourth horizontal tube 104 is connected to the fifth horizontal tube 105 via a movable elbow. The end of the fifth horizontal tube 105 away from the third vertical tube 113 is connected to the discharge hose 401 via an elbow, and the discharge hose 401 can be quickly disassembled. Furthermore, a rotating part is provided between the third vertical tube 113 and the fifth horizontal tube 105, such as... Figure 8 and Figure 9As shown, the rotating part includes a spiral bevel gear 402, a first fixing plate 403, a motor 404, and a rotating bevel gear 405. Specifically, the spiral bevel gear 402 is sleeved on the third vertical tube 113. There are two first fixing plates 403, which are fixed to the fifth horizontal tube 105 in opposite directions. That is, the two opposing first fixing plates 403 clamp the fifth horizontal tube 105. In this embodiment, the first fixing plates 403 are fixed by Ω-shaped double-ended screws and bolts. The motor 404 is fixed on one of the first fixing plates 403. The fixing method here adopts the conventional method in the art, so it will not be described in detail. In this embodiment, a threaded connection is used for fixing, which is convenient for later maintenance and replacement. The rotating bevel gear 405 is located at the front end of the drive shaft of the motor 404. Its connection method is conventional in the art, so it will not be described in detail. The rotating bevel gear 405 meshes with the spiral bevel gear 402. Under the drive of the motor 404, the rotating bevel gear 405 rotates, thereby driving the fifth horizontal tube 105 to rotate around the third vertical tube 113 in the horizontal plane.

[0067] Furthermore, please combine Figure 1 , Figure 8 , Figure 9 and Figure 10 The discharge mechanism 40 also includes a support and lifting mechanism, which includes a support frame 406, a diagonal brace 407, a vertical bracket 408, and a wire rope 409. Specifically, the number of support frames 406 is not specifically limited and can be adjusted as needed. In this embodiment, there are two support frames 406. One end of one frame is welded to the side of the first housing 201, and the other end is connected to the third vertical pipe 113 via fasteners, thereby stabilizing the third vertical pipe 113. The other support frame 406 is welded to the side of the second housing 202, and the other end is connected to the third vertical pipe 113 via fasteners. Specifically, a second bearing 122 and a fifth pipe clamp 135 are sequentially fitted onto the third vertical pipe 113. A sixth pipe clamp 136 is fastened to the outer wall of the second bearing 122. The ends of the support frames 406 away from the first housing 201 or the second housing 202 are connected to the fifth pipe clamp 135 or the sixth pipe clamp 136 respectively by welding or riveting. Furthermore, two second fixing plates 412 are fixed on the fifth horizontal tube 105. The two second fixing plates 412 are arranged opposite to each other and are fixed on the fifth horizontal tube 105 by Ω-shaped double-ended screws and bolts. A sleeve rod 411 is provided on the side of one of the second fixing plates 412. One end of the diagonal brace 407 is connected to the sixth tube clamp 136 by a rivet. A sleeve 410 is provided at the end away from the sixth tube clamp 136. The sleeve 410 is sleeved on the sleeve rod 411. In this embodiment, the sleeve 410 and the diagonal brace 407 are integrally formed structures.

[0068] Furthermore, such as Figure 9 and Figure 10As shown in the illustration, in this embodiment, the vertical support 408 is welded to another second fixing plate 412. To ensure the stability of the vertical support 408, it is a triangular support in this embodiment, with its three legs welded to the second fixing plate 412. A steel wire rope 409 passes around the end of the vertical support 408 away from the second fixing plate 412. Both ends of the steel wire rope 409 are fixed to the fifth horizontal pipe 105 and have the same stretching direction. Figure 9 neutralization Figure 10 As shown, both ends of the wire rope 409 are located on the same side of the vertical support 408. Furthermore, a sleeve with an ear plate 413 is fitted around the end of the vertical support 408 where the wire rope 409 is wrapped. Protrusions 414 are provided on the outer wall of the vertical support 408 and at the upper and lower positions of the sleeve with an ear plate 413 to limit the displacement of the sleeve with an ear plate 413. A shackle is installed in the hole of the sleeve with an ear plate 413, and the wire rope 409 passes through the ring of the shackle, such as... Figure 11 As shown. More specifically, such as Figure 12 and Figure 8 As shown, a first ear plate 415 and a second ear plate 416 are welded to the outer wall of the fifth horizontal tube 105. The first ear plate 415 and the second ear plate 416 are located on the same straight line. The first ear plate 415 is connected to one end of the wire rope 409 via a shackle. Figure 12 As shown, the second ear plate 416 is connected to the other end of the wire rope 409 via the tensioner 417, as... Figure 13 As shown, the fifth horizontal tube 105 is stabilized by the tension of the wire rope 409.

[0069] In specific work, such as Figure 1 and Figure 2 As shown, the feeding mechanism 10 is in a telescopic state. One end of the first horizontal pipe 101 of the feeding mechanism 10 is connected to a power pump. When the power pump is started, the material is conveyed. When it is necessary to cast the invert arch on one side, the discharge port 301 rotates to the corresponding position and connects with the flared opening of the fourth horizontal pipe 104 of the discharge mechanism 40 on the corresponding side for discharge. Figure 3 As shown, when the cast invert surface is high, the discharge hose 401 is removed; when the cast invert surface is low, the discharge hose 401 is installed. Furthermore, the motor 404 operates, causing the rotating bevel gear 405 and the spiral bevel gear 402 to work together, causing the fifth horizontal pipe 105 to rotate around the third vertical pipe 113, thereby achieving full material distribution and casting. And because the discharge mechanism 40... Figure 4 As shown, the components are symmetrically arranged on the left and right sides of the traveling mechanism 20, thus enabling symmetrical casting of the inverted arch surface. When forward movement is required, the drive motor in the first housing 201 operates, driving the gear 203 and rack 214 to work together, causing the traveling wheels 212 to move, thereby moving the discharge mechanism 40. The feeding mechanism 10, with the assistance of the movable elbow, extends, as shown... Figure 5 As shown, this allows for the complete pouring of the tunnel invert. Furthermore, since the track beam 211, feeding mechanism 10, and discharging mechanism 40 are all located at the lower part and sides of the invert trestle, they do not obstruct the operation of other construction equipment on the invert trestle, reducing the difficulty of tunnel construction organization and improving tunnel construction efficiency. In addition, the power pump, the drive motor in the first housing 201, and the motor in the second housing 202 can all be controlled by the control console. Only one person needs to operate the control console to achieve automatic material distribution during the pouring process, effectively saving manpower and significantly reducing the labor intensity of workers.

[0070] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0071] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
