Description

Technical Field

[0001] This invention relates to a production equipment and process for adjusting blocks specifically used in concrete inspection wells for municipal engineering projects, belonging to the field of mechanical and automation design. Background Technology

[0002] Currently, inspection wells, as an important component of underground pipelines, are commonly constructed using precast concrete. An inspection well typically consists of two parts: the well shaft and adjusting blocks. A set of well shafts often includes multiple adjusting blocks. These adjusting blocks play a crucial role in urban infrastructure construction, effectively protecting the safe operation of underground pipeline systems and facilitating maintenance and repair. Therefore, the structural stability and quality of the adjusting blocks directly affect the installation and performance of the precast inspection well.

[0003] The production of adjustment blocks in the current technology usually adopts a manual production mode in a fixed station. This not only has the disadvantages of large footprint, high dependence on manual skills, inability to adjust production size and low production efficiency, but also seriously restricts the automation and standardization of inspection wells and other component products.

[0004] In view of the above, this patent application is hereby filed. Summary of the Invention

[0006] To achieve the above design objectives, the flexible manufacturing production line for manhole regulating blocks includes an operating system that forms a circulating conveying process route. An array of mold transfer vehicles for carrying and conveying regulating block molds circulates on the operating system. A material distribution device is installed vertically above the operating system to convey the formula materials for producing regulating blocks from the mixing silo to each regulating block mold.

The outer end of the triangular linkage device is connected to the top of an array of robotic arm rods through an array of connecting rods. The bottom end of the robotic arm rod is provided with a disc-shaped buckle to clamp the mold. The side parts of the array of robotic arm rods are rotatably connected to the support triangle through a set of rotating shafts. The two ends of the triangular linkage extension and retraction power device are fixedly connected to the support triangle and the triangular linkage device, respectively.

[0009] Furthermore, a rotating disk is axially mounted between the top of the base and the bottom of the stabilizer, and the rotation power device drives the rotating disk to rotate horizontally through a gear and rack assembly.

[0010] Furthermore, a height adjustment device is provided on one side of the stabilizer. The height adjustment device includes vertically distributed lifting and lowering rails and a rack. The output end of the horizontal frame lifting power device drives the connecting gear, which meshes with the rack. A horizontal end slider is provided at the end of the horizontal frame, and the horizontal end slider is slidably connected to the lifting and lowering rails.

[0011] Furthermore, at least one set of vibration tables is provided on the operating system. The vibration tables are located vertically below the material outlet of the material distribution device and in the middle of the operating system track. The vibration table includes a vibration table support. Several symmetrically distributed shock-absorbing rubber supports and a vibrator located at the center of the support are connected to the bottom of the vibration table support. The ground where the vibration table is located is slightly higher than the ground where the operating track is located.

[0012] Furthermore, a leveling machine for surface leveling of components is provided on one side of the operating system. The leveling machine includes a cantilevered body and a leveling telescopic hydraulic cylinder is provided at the cantilever end of the body. The output shaft of the leveling telescopic hydraulic cylinder drives the center of the cross-shaped joint vertically. A double-layer hollow annular leveling frame is fixedly connected to the vertical bottom of the cross-shaped joint.

[0013] Furthermore, the material placing device includes a material placing frame, a hopper trolley frame on the material placing frame driven by a hopper drive motor to carry the hopper, the hopper carrying concrete material for producing adjusting blocks, and a screw feeder extending vertically downward on the material placing frame and driven by a feeding drive motor.

[0014] Furthermore, the operating system includes an operating track composed of a first transverse track section, a second transverse track section, and a longitudinal track transfer section. A mold transfer car track for carrying the mold transfer car is installed above each operating track. At the corners where the first and second transverse track sections overlap with the longitudinal track transfer section, the first and second transverse track sections are disconnected. A longitudinal track transfer section is laid vertically below the disconnected first and second transverse track sections. Each longitudinal track transfer section includes a mold transfer car track forming a circular operating route. A transfer trolley carrying the disconnected first and second transverse track sections runs below the mold transfer car track. The transfer trolley runs on the lower longitudinal transfer section, and each set of longitudinal track transfer sections has one set of transfer trolleys. A set of pusher cylinders is installed at the transverse ends of the first and second transverse track sections, and a set of pusher cylinders is installed at both longitudinal ends of the first and second transverse track sections.

[0015] Based on the structural design of the above-mentioned flexible manufacturing production line for manhole regulating blocks, this application also proposes a flexible manufacturing method for manhole regulating blocks, which includes the following implementation steps:

[0016] Step 1: Stir and add ingredients;

[0017] The raw materials are mixed and stirred in the mixing silo, and the proportioned raw materials are transported to the pouring position via the hopper.

[0018] The assembled adjusting block mold is placed on the mold transfer vehicle and moved along the first transverse track section to the vertical direction below the screw feeder;

[0019] The concrete material is continuously mixed by a screw feeder to prevent clumping and then conveyed to the regulating block mold;

[0020] Step 2: Pouring and vibrating;

[0021] The screw feeder injects concrete material from the protrusion at the top of the core mold, and the material is dispersed and flows evenly by gravity. Then, the hydraulic jack at the first track is activated, the first track descends, the mold transfer car falls onto the vibrating table and is started by the vibrator to perform in-situ vibration. After the vibration is completed, the first track moves back to its original height position, the mold transfer car separates from the vibrating table and returns to the first track.

[0022] Step 3: Surface leveling;

[0023] The mold transfer vehicle moves along the first track to the position below the leveling machine, and the double-layer hollow ring leveling frame moves up and down and rotates to level the concrete on the upper surface of the component.

[0024] Step 4: Transfer and demolding;

[0025] The mold transfer vehicle moves and moves to one side of the component transfer device on the second track;

[0026] The circular clip at the end of the robotic arm of the component transfer device is engaged with the bottom of the bottom mold ring to lift the outer mold ring, the bottom mold ring, and the component together and transfer them to the conveyor belt. The bottom mold ring is then replenished on the mold transfer vehicle at the original work station.

[0027] On the conveyor belt, the disc-shaped buckle of the robotic arm moves vertically upward to clamp the bottom of the upper edge of the outer mold ring. It continues to move upward to remove the outer mold ring from the component on the conveyor belt. The outer mold ring is then placed back on the replenished bottom mold ring on the mold transfer car. The complete set of molds is then circulated along the track by the mold transfer car.

[0028] Step 5: Transfer and maintenance;

[0029] The components are transported to the curing kiln via conveyor belt for curing.

[0030] In summary, the advantages of the flexible manufacturing production line and method for manhole regulating blocks described above are:

[0031] 1. This application realizes a fully automated and intelligent continuous production equipment, which makes the related manufacturing process more flexible and efficient, and significantly improves the production quality and use effect of the overall product of regulating blocks and inspection wells.

[0032] 2. This application adopts a raised core mold design, which facilitates the dispersion of concrete during material feeding and ensures its uniform distribution within the mold, reducing manual intervention in paving; at the same time, it is designed with an in-situ vibration table after pouring, adopting an immediate vibration and leveling process after pouring, which effectively improves the flatness of the component surface and significantly enhances product quality.

[0033] 3. This application combines six sets of retractable hydraulic cylinders to form a mold transfer vehicle with an overall cyclic operation process. The production line has a high level of automation, which greatly reduces the participation of on-site workers. The prefabrication efficiency of the adjustment block is significantly improved. In addition, it can adapt to the prefabrication of modules of different sizes and diameters during the production process, which completely changes the current construction status of traditional inspection wells.

[0034] 4. This application adopts an adjustable height component transfer device, which realizes flexible adjustment of component transfer height and can adapt to the production of components of different heights. The demolding design of the robotic arm is also conducive to improving the demolding and transfer efficiency of components and adjustment block molds, and can help the overall production process of adjustment blocks be implemented smoothly and efficiently.

[0061] The present invention will be further described below with reference to the accompanying drawings and embodiments, and the technical solutions in the embodiments will be clearly and completely described.

[0062] Example 1, such as Figures 1 to 14As shown, the flexible manufacturing production line for manhole adjustment blocks includes an operating system 3 that forms a circulating conveying process route. An array of mold transfer vehicles 4 for carrying and conveying adjustment block molds 5 circulates on the operating system 3. At least one set of vibrating tables 6 are provided on the operating system 3. A material distribution device 2 for conveying the formula materials for producing adjustment blocks from the mixing bin 1 to each adjustment block mold 5 is provided vertically above the operating system 3. A leveling machine 7 for surface leveling of components is provided on one side of the operating system 3. A component transfer device 8 for conveying the adjustment block molds 5 into the curing kiln 10 via a conveyor belt 9 is provided on one side of the operating system 3.

[0063] Specifically, the material placing device 2 includes a material placing frame 20, a hopper trolley frame 211 driven by a hopper drive motor 212 on the material placing frame 20 to support the hopper 21, the hopper 21 carrying concrete material for producing adjusting blocks, and a screw feeder 22 extending vertically downward and driven by a feeding drive motor 221 on the material placing frame 20; the concrete material is unloaded from the hopper 21 into the screw feeder 22, and pushed and poured by the screw feeder 22 into the adjusting block mold 5 on the vertically downward running system 3.

[0064] The operating system 3 includes an operating track composed of a first transverse track section 31, a second transverse track section 32, and a longitudinal track transfer section 33. A mold transfer car track 34 carrying the mold transfer car 4 is set above the operating track. At the corners that overlap with the longitudinal track transfer section 33, the first transverse track section 31 and the second transverse track section 32 are broken. A longitudinal track transfer section 33 is laid vertically below the first transverse track section 31 and the second transverse track section 32 at the break. Each longitudinal track transfer section 33 includes a mold transfer car track 34 that forms a circular operating line. A transfer car 333 carrying the track of the first transverse track section 31 and the second transverse track section 32 at the break runs below the mold transfer car track 34. The transfer car 333 runs on the lower longitudinal transfer section 33. Each set of longitudinal track transfer sections is equipped with one set of transfer cars.

[0065] The first transverse track section 31 includes a first track 311, and the second transverse track section 32 includes a second track 312. The first track 311 and the second track 312 are arranged parallel to each other.

[0066] One set (two sets in total) of trolley cylinders 35 are respectively installed at the transverse ends (i.e. the disconnection points) of the first track 311 and the second track 312, and one set (four sets in total) of trolley cylinders 35 are respectively installed at the longitudinal ends of the first track 311 and the second track 312, which can realize the turnover of the shuttle trolley 333 within the longitudinal track shuttle section 33.

[0067] An array of mold transfer carts 4 are running on the first track 311 and the second track 312. Relying on a set of trolley cylinders 35 set at the transverse end, the mold transfer carts 4 move transversely in sequence, each time traveling one cart length of workstation.

[0068] When a mold transfer car 4 travels to the point where the first track 311, the second track 312, and the longitudinal track transfer section 33 overlap, a set of pusher cylinders 35 at the longitudinal end pushes the transfer trolley 333 to directly push the mold transfer car 4 from the first track 311 (or the second track 312) to the point where the second track 312 (or the first track 311) is disconnected. Subsequently, on the one hand, the pusher cylinders 35 at the transverse end of the first track 311 (or the second track 312) push the mold transfer car 4 forward to continue running; on the other hand, another set of pusher cylinders 35 at the longitudinal end of the second track 312 (or the second track 312) pushes the transfer trolley 333 back to the original point where the first track 311 (or the first track 311) is disconnected, in order to wait for the next set of mold transfer cars 4 to transfer.

[0069] The mold transfer vehicle 4 includes a trolley frame 40, on which four sets of wheels 41 running on a track are installed, and an adjustment block mold 5 is placed on top of the trolley frame 40.

[0070] The adjusting block mold 5 includes a core mold 53. A cone-shaped protrusion 531 is provided in the center of the core mold 53. A number of symmetrically arranged support ribs 532 are provided around the protrusion 531 and at the bottom of the core mold 53. A bottom mold ring 51 is placed on top of the support ribs 532. An outer mold ring sleeve 52 is placed on top of the bottom mold ring 51. The outer mold ring sleeve 52 is composed of an annular upper edge 521, a lower edge 522 and a vertical closed connection structure 523 between them.

[0071] The adjusting block mold 5 with the above-mentioned structural design, when the concrete material is pushed by the screw feeder 22 to the inner wall of the outer mold ring 52 and the outer wall of the core mold 53, completes the uniform distribution of concrete material through the dispersion and diversion of the conical protrusion 531.

[0072] The vibration table 6 is located vertically below the discharge port of the screw feeder 22 and in the middle of the first transverse track section 31 to vibrate the mold transfer car 4 on it. The vibration table 6 includes a vibration table support 61, and four symmetrically distributed shock-absorbing rubber supports 62 and a vibrator 63 located in the center of the support are connected to the bottom of the vibration table support 61. The ground where the vibration table 6 is located is slightly higher than the ground where the running track is located.

[0073] The first transverse track section 31 (such as the first track 311) is broken at the position of the vibration table 6. Four sets of limiting brackets 3111 are symmetrically arranged on the outside of the first track 311 to prevent the first track 311 from shifting position when it vibrates vertically. At the bottom of the first transverse track section 31 (such as the first track 311), four sets of hydraulic jacks 3112 are symmetrically arranged to provide stable lifting support.

[0074] When the vibrator 63 is started, the concrete material in the adjusting block mold 5 can be vibrated and evenly mixed through the vibration table support 61 and the mold transfer vehicle 4 in contact with it, further improving the uniformity of material distribution in the mold.

[0075] The leveling machine 7 includes a cantilevered body 71. A leveling telescopic hydraulic cylinder 74 is installed at the cantilever end of the body 71. The output shaft of the leveling telescopic hydraulic cylinder 74 is vertically driven to the center of a cross-shaped connector 72. A double-layer hollow annular leveling frame 73 is fixedly connected to the vertical bottom of the cross-shaped connector 72. The horizontal bottom of the double-layer hollow annular leveling frame 73 has the same area and shape as the top of the outer mold ring 52. Driven by the leveling telescopic hydraulic cylinder 74, the double-layer hollow annular leveling frame 73 moves up and down vertically. When the double-layer hollow annular leveling frame 73 is pressed down to the top of the outer mold ring 52, it can level the concrete material inside, thereby effectively improving the flatness of the component surface.

[0076] The component transfer device 8 includes a base 81, a stabilizing frame 84 that is horizontally rotatably connected to the top of the base 81, a horizontal frame 85 that is vertically slidably connected to one side of the stabilizing frame 84, a robotic arm 87 that is vertically connected to the end of the horizontal frame 85, and a power unit.

[0077] The power unit includes a rotational power unit 821 for driving the horizontal rotation of the stabilizer 84, a horizontal lifting power unit 822 for driving the vertical lifting of the horizontal frame 85, a mechanical arm shaft extension power unit 823 for driving the mechanical arm 87 to lift vertically along the end of the horizontal frame 85, and a triangular linkage retraction power unit 824 for the mechanical arm 87 to extend and retract radially. Through the coordinated operation of the above four power units, the transfer of components between the running system 3 and the conveyor belt 9 can be realized.

[0078] Furthermore, the rotary power device 821 for driving the horizontal rotation of the stabilizer 84 and the horizontal frame lifting power device 822 for driving the vertical lifting of the horizontal frame 85 are preferably servo motors; the mechanical arm shaft extension power device 823 for driving the mechanical arm 87 to lift vertically along the end of the horizontal frame 85 and the triangular linkage extension and retraction power device 824 for the mechanical arm 87 to extend and retract radially are preferably hydraulic cylinders; furthermore, a rotating disk 83 is axially provided between the top of the base 81 and the bottom of the stabilizer 84, and the rotary power device 821 drives the rotating disk 83 to rotate horizontally through a gear and rack assembly, thereby transmitting the stabilizer 84 together with the horizontal frame 85, the horizontal frame 85 and the mechanical arm 87 to rotate to any position within 360°;

[0079] Furthermore, a height adjustment device 86 is provided on one side of the stabilizer 84. The height adjustment device 86 includes vertically distributed lifting and lowering rails 861 and rack 863. The output end of the horizontal frame lifting power device 822 drives and connects to the gear 862, which meshes with the rack 863. A horizontal end slider 851 is provided at the end of the horizontal frame 85, and the horizontal end slider 851 is slidably connected to the lifting and lowering rails 861. Under the drive of the horizontal frame lifting power device 822, the horizontal frame 85 can be vertically raised and lowered along one side of the stabilizer 84.

[0080] Furthermore, the landing track 861 is provided with several holes 864 to facilitate connection with other components;

[0081] The robotic arm 87 includes a support triangle 872 and a triangle linkage device 873 that are vertically connected by a robotic arm shaft telescopic power device 823. The support triangle 872 is driven by the robotic arm shaft telescopic power device 823 to move vertically and is fixedly connected to the output end of the robotic arm shaft telescopic power device 823 in the horizontal direction, and the two have no relative displacement in the horizontal direction.

[0082] The outer end of the triangular linkage device 873 is connected to the top of the top of the three sets of robotic arms 871 via three sets of connecting rods 875. The bottom of the robotic arms 871 is provided with a disc-shaped buckle to facilitate clamping the mold. The sides of the three sets of robotic arms 871 are rotatably connected to the supporting tripod 872 via a set of rotating shafts 874. The two ends of the triangular linkage retraction and extension power device 824 are fixedly connected to the supporting tripod 872 and the triangular linkage device 873, respectively. Under the extension and retraction drive of the triangular linkage retraction and extension power device 824, the triangular linkage device 873 deflects in the horizontal direction, thereby driving the three sets of robotic arms 871 to retract and extend radially at the same time to clamp or release the mold.

[0083] Based on the structural design of the above-mentioned flexible manufacturing production line for manhole regulating blocks, this application also proposes the following flexible manufacturing method for manhole regulating blocks:

[0084] Step 1: Stir and add ingredients;

[0085] The raw materials are mixed and stirred in the mixing bin 1, and the proportioned raw materials are transported to the pouring position via the hopper 21.

[0086] Meanwhile, the assembled adjusting block mold 5 is placed on the mold transfer vehicle 4 and moves along the first transverse track section 31 to the vertical direction below the screw feeder 222;

[0087] The concrete material is continuously mixed by the screw feeder 22 to prevent clumping and then conveyed to the regulating block mold 5;

[0088] Step 2: Pouring and vibrating;

[0089] The spiral feeder 22 injects concrete material through the protrusion 531 at the top of the core mold 53, and the material is dispersed and flows evenly by gravity. Subsequently, the four sets of hydraulic oil tops 3112 at the first track 311 are activated, the first track 311 is lowered, the mold transfer car 4 falls onto the vibrating table 6 and is started by the vibrator 63 to perform in-situ vibration. After the vibration is completed, the first track 311 moves up to the original height position, the mold transfer car 4 separates from the vibrating table 6 and returns to the first track 311.

[0090] Step 3: Surface leveling;

[0091] The mold transfer vehicle 4 moves along the first track 311 to the vertically downward position of the leveling machine 7, and the double-layer hollow ring leveling frame 73 moves up and down and rotates to level the concrete on the upper surface of the component.

[0092] Step 4: Transfer and demolding;

[0093] The mold transfer vehicle 4 moves and transfers the mold to the second track 312, one side of the component transfer device 8;

[0094] The disc-shaped buckle at the end of the mechanical arm 871 of the component transfer device 8 is engaged with the bottom of the bottom mold ring 51 to lift the outer mold ring 52, the bottom mold ring 51 and the component together and transfer them to the conveyor belt 9, and the bottom mold ring 51 is replenished on the mold transfer car 4 at the original work position.

[0095] On the conveyor belt 9, the disc-shaped buckle of the robotic arm 871 moves vertically upward to clamp the bottom of the upper edge 521 of the outer mold ring 52. It continues to move upward to remove the outer mold ring 52 from the component on the conveyor belt 9. The outer mold ring 52 is then placed back on the bottom mold ring 51 on the mold transfer car 4. The complete set of molds is then circulated along the track via the mold transfer car 4.

[0096] Step 5: Transfer and maintenance;

[0097] The components are transported to the curing kiln 10 via conveyor belt 9 for curing operations.

[0098] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
