Description
Technical fields:
[0001] This invention belongs to the field of tunnel lining equipment, and specifically relates to a multi-functional windowed concrete placing machine, which adopts a suspended concrete placing pipe and is equipped with an expandable folding pipe assembly, and can extend from the end of the secondary lining trolley to complete the entire process of pouring. Background technology:
[0002] In tunnel secondary lining concrete construction, lining trolleys are used as the formwork system, and concrete is then pumped into the formwork for pouring. A secondary lining trolley generally includes a gantry, bottom beam, hydraulic formwork rods, upper frame, top formwork, and side formwork; while the concrete placement system includes a concrete placing boom, pouring pipes, and pouring windows. When using traditional methods for secondary lining concrete construction, to achieve symmetrical horizontal and vertical layered pouring, multiple concrete inlet windows (concrete inlet windows) are typically opened along the tunnel axis on the left and right sides of the trolley, and in upper, middle, and lower layers. Concrete is delivered from the pump outlet to each inlet window via detachable feed pipes. However, the process of laying, dismantling, and reinstalling pipes for each window is inefficient. Therefore, various solutions have been developed, such as:
[0003] Patent application number 201220331471.7 discloses a concrete placing device based on a tunnel secondary lining concrete construction trolley, including a reversing pipe for conveying concrete and multiple concrete inlet chutes connected to the formwork windows on the trolley. The reversing pipe is located above the multiple concrete inlet chutes, and its outlet end can switch between the multiple concrete inlet chutes. By installing the inlet chutes once and then distributing the concrete pouring one by one, the efficiency problem is solved, but it also requires the preparation of chutes of different lengths and specifications, increasing the trouble during installation.
[0004] Patent application number 201721893372.7 discloses a layered, window-by-window pouring and cleaning system for tunnel lining trolleys, including template units, grouting ports, pouring ports, a piping system, and a concrete placement system. Multiple template units are connected sequentially to form an arch structure, creating a pouring area on the inner side of the arch structure. Multiple grouting ports are positioned at the arch apex on the outer side of the arch structure, arranged circumferentially and axially. The piping system includes multiple concrete pipes, one end of which leads to each pouring port, and the other end connects to the grouting port. The concrete placement system includes a concrete pump, a delivery pipe, a placement trolley, and a placement platform. The concrete pump is connected to the placement trolley via the delivery pipe. The placement platform has tracks on which the placement trolley moves, and each placement trolley has a delivery port corresponding to a grouting port. While the placement trolley achieves axial, window-by-window concrete distribution, the problems of pipe placement and the connection between the placement trolley and each pipe remain.
[0005] In light of the shortcomings of the aforementioned mechanisms, the applicant has developed an alternative solution, which is documented in the patent gazette as CN202120616868.X. This patent discloses a boom-type secondary lining trolley window-by-window concrete placement mechanism, comprising a concrete placement tube, a flipping concrete placement head, and a cantilever positioned on the top of the secondary lining trolley. The concrete placement tube is supported by the cantilever and connects the feed end and the flipping concrete placement head. The cantilever is inserted into a tube seat fixed to the top platform of the gantry assembly, and the tube seat supports the cantilever in a horizontal state. A drive mechanism is provided between the tube seat and the cantilever to drive the cantilever to move horizontally relative to the tube seat. A hanger is provided at one end of the cantilever, and the concrete placement tube is fixed to the hanger, with the end with the flipping concrete placement head suspended in the air. A distribution tube and an unfoldable folding tube assembly are provided on the hanger, through which concrete material is fed and then connected to the concrete placement tube. This invention features ingenious design, simple structure, flexible operation, smooth feeding, and high construction efficiency.

[0022] The material distribution head assembly includes a material distribution seat, a swing frame assembly, an inlet connector, and an outlet connector. The material distribution seat has a vertical material distribution plate and a shaft seat perpendicular to the material distribution plate. The material distribution plate is provided with an arc groove and an arc edge centered on the axis of the shaft seat. The material distribution plate is provided with two to three outlet connectors, which connect with the corresponding outlet concrete pipes on the left and right sides. The swing frame assembly includes a swing bushing, a telescopic frame, and a clamping cylinder. The telescopic frame is composed of several pipes distributed in two layers, inner and outer, centered on the axis of the swing bushing. The pipes are locked together at both ends and the middle by a front frame plate, a middle frame plate, and a rear frame plate. The pipes are respectively... A clamping rod is inserted, with a T-shaped head at the front end and a clamping plate at the rear end. The T-shaped head at the front end is engaged with the arc groove and the leading edge of the arc edge of the material distribution plate.

After placing the concrete, it does not affect the relocation of the secondary lining trolley. Furthermore, the separately arranged intervals allow for necessary curing of the concrete section using the matching spray pipes, and facade repair work can be carried out using a suspended platform. Overall, the machine features ingenious design, flexible operation, smooth feeding, and high construction efficiency, achieving segmented concrete placing, section curing, and repair functions.

[0066] Reference Figure 1 A multi-functional window-splitting concrete placing machine, equipped with a secondary lining trolley, completes the concrete window-splitting pouring operation, including:
[0067] Reference Figure 2 , Figure 4 , Figure 6 and Figure 7 The frame assembly 1 includes door beams 11, bottom beams 12, wheels 13 mounted on the bottom beams, and a lifting seat 14. The lower ends of two or more door beams 11 are fixed to two bottom beams 12 arranged left and right to form a frame assembly. The wheels 13 and the lifting seat 14 are respectively mounted on the lower sides of the two ends of the bottom beams 12 and can be supported on the ground. One pair of wheels 13 are drive wheels driven by a motor, which can drive the frame assembly 1 to move forward and backward. After the lifting seat 14 moves into position, it is supported on the ground to provide a larger load-bearing area. A pair of guide rails 15 are also provided between the door beams 11. The guide rails 15 are located on both sides of the top of the door beams 11 and are parallel to the bottom beams 12.
[0068] Furthermore, the lifting seat 14 includes a lifting sleeve 141, a lifting cylinder 142, a transverse pad 143, and a transverse movement cylinder 144. The upper part of the lifting sleeve 141 passes through the vertical hole of the bottom beam 12, and the lifting cylinder 142 is arranged between the two. The lifting cylinder 142 drives the lifting seat 14 to move downward, supporting it on the ground and maintaining the stability of the frame assembly 1, which is beneficial for construction. The lower end of the lifting sleeve 141 is slidably embedded in the transverse pad 143, and the transverse movement cylinder 144 is arranged between the two. The transverse pad 143 has a larger bearing area and better load-bearing capacity, and the larger area also facilitates movement and adjustment. The transverse cylinder 144 can drive the frame assembly 1 to adjust laterally, realizing docking with the secondary lining trolley 7. Figure 4 , Figure 6 and Figure 7 .
[0069] Reference Figure 2 , Figure 3 , Figure 8 and Figure 9 The guide rail 15 has a double tube structure, and a rack 151 is also set between the two round tubes; the pedestal car 2 is equipped with double-row track wheels 22, which can roll and clamp on the two round tubes; after the walking motor 23 is reduced, each end of the output shaft 231 is locked with a gear 232, and the pedestal car 2 is driven to move by the meshing of the gear 232 and the rack 151.
[0070] The platform trolley 2 includes a chassis 21, track wheels 22, and a travel motor 23. The track wheels 22, mounted at the bottom of the chassis 21, travel on a pair of guide rails 15 on top of the frame assembly, driven by the travel motor 23. The platform trolley 2 carries the material distribution head assembly, cantilever, and material distribution pipe, reciprocating within the longitudinal space of the gantry beam. It also serves as the operating platform for the personnel; therefore, it is surrounded by guardrails 24. Figure 8 .
[0071] Reference Figure 2 , Figures 10 to 14 The material distribution assembly 3 includes a hopper 31, a concrete pump 32, a concrete inlet pipe 33, a material distribution head assembly 34, and a concrete outlet pipe 35. Concrete is pumped from the hopper 31 end by the concrete pump 32 through the swingable concrete inlet pipe 33 to the material distribution head assembly 34. The material distribution head assembly 34 then supplies concrete to the concrete outlet pipe 35, which is fixed on the pier 2. The rear end of the concrete outlet pipe 35 is connected to the distribution pipe 36. The hopper 31 and the concrete pump 32 are positioned on one side of the frame assembly 1 to maintain a relatively stable position for the concrete truck to deliver the material.
[0072] Reference Figure 2 , Figure 10 and Figure 11 The cantilever 4 includes a fixed arm 41 supporting the end of the concrete placing pipe and a swing arm 42 supporting the end of the concrete feeding pipe. The fixed arm 41 has an inclined arm 411 and a horizontal arm 412, which are rigidly connected in an L-shape. The upper end of the inclined arm 411 is locked to the pier 2, and the horizontal arm 412 is parallel to the guide rail 15 and points in the forward direction of the frame assembly 1, and can penetrate into the secondary lining trolley 7. The concrete placing pipe 36 is arranged and fixed along the fixed arm. The two concrete placing pipes 36 are located on both sides of the frame assembly 1, which not only meets the requirements of placing concrete in windows on the sides of the tunnel, but also allows the two placing heads to complete the placement of concrete at the top by means of the swing range of the placing head. If the tunnel is an extra-wide structure, another concrete placing pipe 36 can be arranged at the center of the top of the portal beam 11 to make up for the insufficient space of the placing pipes on both sides. During the concrete placing operation, the pier 2 is moved and the placing head swings appropriately to complete the placement window by window, without the need for the extension and retraction of the concrete placing pipe 36, which greatly simplifies the design.
[0073] Therefore, a trolley 43 is provided at the end of the horizontal arm 412 of the fixed arm. The trolley 43 can travel on a side rail 71 fixed to the side of the secondary lining trolley 7, forming a support for the suspended end of the horizontal arm 412, providing more stable support for the fabric head operation.
[0074] The swing arm 42 includes a first swing arm 421 and a second swing arm 422. One end of the first swing arm 421 is rotatably positioned on the side of the gantry beam 11, and the other end is rotatably hinged to one end of the second swing arm 422. The other end of the second swing arm 422 is rotatably hinged to the pier carriage 2 and can be swayed by the pier carriage 2. The concrete feed pipe 33 is arranged along the first swing arm 421 and the second swing arm 422 of the swing arm. It is connected at the rotatable hinge of the swing arm 42 by a bent pipe bearing 331 coaxial with it. Together with the swing arm 42, it swings, extends, and retracts as it moves with the pier carriage 2 to meet the supply needs without the need for additional power or control. This is one of the features of this design.
[0075] Reference Figure 1 and Figure 2 An arched spray pipe 5 is installed at the front end of the pier car 2. The spray pipe 5 has evenly distributed outward-facing spray heads. The spray pipe 5 is supplied with water by a high-pressure water pump and can spray the tunnel facade. By utilizing the movement of the pier car 2, the maintenance needs of the entire section can be met. The structure is simple and can complete the maintenance task incidentally without the need for additional facilities.
[0076] Reference Figure 1 , Figure 4 , Figure 5 ,as well as Figure 15 and Figure 16 A basket assembly 6 is installed in the middle of the crossbeam 111 of the rear door beam of the frame assembly 1. This assembly includes a telescopic arm 61 and a basket 62. The telescopic arm 61 consists of two or more nested square tubes. Telescopic cylinders 63 are installed between adjacent square tube sections, driving the arm to extend and retract section by section. A fixed shaft 64 is installed at the end of the first square tube section 611 of the telescopic arm 61, and the arm is rotatably positioned on the crossbeam 111 via the fixed shaft 64. A reducer 65, connected to a motor drive, is installed on the crossbeam 111. A small gear 651 on the output shaft of the reducer 65 meshes with a large gear 641 locked on the fixed shaft 64, driving the telescopic arm 61 to swing 360 degrees. A support shaft 66 is installed on the last square tube section 612 of the telescopic arm 61, and the basket 62 is suspended on the support shaft 66.
[0077] More specifically, the suspended platform 62 has a back plate 621 at its back, and a bushing 622 is provided on the upper part of the back plate 621. The bushing 622 is rotatably fitted onto the support shaft 66. An end cap 661 is locked to the end of the support shaft 66, and a brake arm 662 extends radially from the end cap. A brake rod 663 is threaded onto the brake arm 662, and a brake disc 664 is provided at the inner end of the brake rod. The brake disc 664 can abut against the back plate 621 of the suspended platform to form a brake and prevent the suspended platform 62 from being too flexible and affecting the construction operation. After the brake disc 664 is released, the flexible suspended platform 62 can always maintain an upward position under its own weight when the telescopic arm 61 swings. The outer end of the brake rod 663 has an external hexagonal structure or a crank to facilitate the operation of tightening and loosening the brake rod 663. The illustration shows a hexagonal structure, which can be adjusted with a wrench.
[0078] This concrete placing boom example uses a two placing pipes 36. Therefore, the material distribution head assembly 34 has a one-in-two-out structure, which can be applied to existing concrete switching valves. The following is an optimized solution.
[0079] Reference Figure 12 , Figure 13 and Figure 14 The material distribution head assembly 34 includes a material distribution seat 341, a swing frame assembly 342, a feeding connector 343, and a discharging connector 344. The material distribution seat 341 has a vertical material distribution plate 3411 and a bearing 3412 perpendicular to the material distribution plate. The material distribution plate 3411 is provided with an arc groove 3413 centered on the axis of the bearing 3412 and an arc edge 3414. The material distribution plate 3411 is provided with two to three discharging connectors 344, which connect with the corresponding discharge concrete pipes 35 on the left and right sides and convey the material to the corresponding distribution pipes 36.
[0080] The swing frame assembly 342 includes a swing bushing 3421, a telescopic frame 3422, and a clamping cylinder 3423. The telescopic frame 3422 is composed of several tubular components arranged in two layers, inner and outer, with the axis of the swing bushing 3421 as the center line. The two ends and the middle section of the tubular components are respectively secured to the assembly by a front frame plate 3424, a middle frame plate 3425, and a rear frame plate 3426. Clamping rods 3427 are correspondingly inserted into the tubular components. The front end of the clamping rod is a T-shaped head 3428, formed directly by a locking nut, and the rear end is locked to a clamping plate 3429. The T-shaped head 3427 at the front end... 28 is secured to the front edge of the arc groove 3413 and arc edge 3414 of the material distribution plate. The front frame plate 3424 can abut against the rear edge of the material distribution plate 3411 to form a valve. A clamping cylinder 3423 is provided between the rear frame plate 3426 and the clamping plate 3429. The clamping cylinder 3423 is used to keep the front frame plate 3424 and the material distribution plate 3411 in close contact to prevent mud and water from leaking out. When released, the swing frame assembly 342 is allowed to swing to switch which discharge joint 344 the feed joint 343 is connected to, and the corresponding material distribution pipe 36 is provided for material distribution.
[0081] like Figure 13 The feed connector 343 has a zigzag structure. The upper section is located between the front frame plate 3424 and the middle frame plate 3425. The middle section is a curved structure that is fixedly connected to the swing sleeve 3421. The lower section extends backward, with at least the axis of the extended port overlapping the axis of the swing sleeve 3421. It is connected to the feed concrete pipe 33 via a pipe bearing, allowing the feed connector 343 to swing with the swing frame assembly 342. The swing frame assembly 342 is positioned on the bearing seat 3412 of the distribution seat via the swing sleeve 3421 and a rotating shaft. When it is necessary to switch which side of the distribution pipe 36 to feed, the clamping cylinder 3423 is first depressurized, and the T-shaped head at the end of the clamping rod 3427 is released from the clamping state with the distribution plate 3411. The swing frame assembly 342 is manually adjusted to the required position, and the clamping cylinder 3423 is activated again, pushing the clamping rod 3427 backward so that the front frame plate 3424 is pressed against the distribution plate 3414. In the two-station structure, the two ends of the circular arc groove 3413 are used as the stroke points, and the swing can be completed to the end.
[0082] Two to three discharge joints 344 on the distribution plate 3411 are located on the same arc centered on the axis of the bearing 3412, and can be aligned and connected with the feed joint 343 on the front frame plate 3424 of the swing frame assembly. A water-air interface 37 is also provided in the space on the same arc of the distribution plate 3411 and the front frame plate 3424. This water-air interface 37 is connected to a water-air valve group 38 via a high-pressure pipe. The water-air valve group 38 is connected to a high-pressure water pump and a high-pressure air pump, and the water-air supply is controlled by corresponding valves. Before switching the discharge joints, the swing frame assembly 342 is swung to the middle position so that both the feed joint 343 and the discharge joint 344 are aligned with the water-air interface 37.
