Description

Technical Field

[0001] This invention relates to the field of arch frame casting technology, specifically to a casting equipment for constructing highway arch frames. Background Technology

[0002] During the construction of highways and railways, frequent high fills and deep excavations will create a large number of exposed slopes. These unstable slopes are not only prone to soil erosion, slope collapse, debris flow and other disasters, but also greatly damage the ecological environment along the route. In order to protect the slopes around the highway, it is necessary to lay arched frames on the slopes for slope protection, so as to ensure that the slopes will not be damaged by external factors.

[0003] However, the traditional highway arch frame requires pre-formwork during concrete pouring, followed by concrete injection into the mold and subsequent demolding. This involves a large amount of work and is also quite complicated to construct on steep slopes. The manual back-and-forth operation is time-consuming and labor-intensive, which is very inconvenient and reduces the overall work efficiency. Summary of the Invention

[0004] To address the problems in the prior art, this invention provides a casting device for constructing a highway arch frame.

[0008] Specifically, the casting mechanism includes a mounting frame, with the mounting frame installed on one side of the mounting plate. A sliding mold is installed at the bottom of the mounting frame, and the sliding mold has arc-shaped structures on both sides. A hopper is vertically connected to one end of the top of the sliding mold, and the bottom of the hopper extends to the inner side of the bottom of the sliding mold. A third motor is detachably connected to the outer side of one end of the sliding mold, and a screw rod is rotatably connected to the inside of one end of the sliding mold. The output shaft of the third motor is connected to one end of the screw rod, and the screw rod is located at the bottom of the hopper.

[0009] Specifically, the drive mechanism includes a rack, and two parallel and symmetrical racks are installed at the top edge of the support arm. The support arm is slidably connected to the slide and the working arm. Two gears are rotatably connected inside the slide and the working arm, and the two gears mesh with the two racks respectively. Two first motors are detachably installed at the top of the slide and the working arm, and the output shafts of the first motors are connected to the gears respectively.

[0010] Specifically, the installation mechanism includes a retaining sleeve. Multiple retaining sleeves are arranged longitudinally and equidistantly at the center of the hopper. The retaining sleeves are circular ring structures. Two support rods are installed on the outer side of the multiple retaining sleeves. The support rods are perpendicularly connected to the inner wall of the hopper.

[0011] Specifically, one of the ferrule sidewalls is vertically threaded with a screw, the screw being a cylindrical "T"-shaped structure, with one end of the screw extending to the inside of the ferrule.

[0012] Specifically, a clamping plate is slidably connected inside the side wall of the ferrule. The clamping plate has an arc-shaped structure, with one side of the clamping plate extending to the outside. An anti-slip pad is installed on one side of the clamping plate, and one end of the screw is rotatably connected to the center of the other side of the clamping plate.

[0013] Specifically, the support mechanism includes a horizontal plate, a horizontal plate rotatably connected to the end of the support arm, the horizontal plate being perpendicular to the support arm, a third hydraulic cylinder rotatably connected to the bottom side of the support arm, one end of the third hydraulic cylinder being rotatably connected to the center of one side of the horizontal plate, support feet rotatably connected to both ends of the horizontal plate, insert rods respectively installed at the bottom of the two support feet, and fourth hydraulic cylinders rotatably connected to the bottom of both ends of the horizontal plate, one end of each of the two fourth hydraulic cylinders being rotatably connected to one side of each of the two support feet.

[0014] The beneficial effects of this invention are:

[0015] (1) The highway arch frame construction and pouring equipment of the present invention facilitates the installation of the rotating mechanism and the pouring mechanism through the control mechanism. By controlling the rotating mechanism and the pouring mechanism, the concrete pouring work on steep slopes can be realized, and the concrete forming is smooth and beautiful. That is: the installation of the support arm facilitates the support and connection of the working arm; the operation of the first hydraulic cylinder realizes the adjustment of the elevation angle of the working arm, which facilitates the adjustment of the angle of the support arm on the working arm, so as to realize the pouring of concrete on different slopes; the installation of the sliding seat facilitates the installation and control of the slipform, so as to realize the concrete pouring and forming on the slope; the installation of the connecting arm facilitates the connection of the mounting plate; and the connection of the mounting plate... The system facilitates the installation of the slipform. The height of the slipform can be adjusted via the operation of the second hydraulic cylinder to enable pouring. The rotation angle of the connecting arm can be controlled via the installation of the second motor, allowing concrete to be poured inside the arc-shaped groove of the slipform, making operation more convenient. The installation of the mounting frame facilitates the connection of the slipform, and the installation of the hopper facilitates the storage of concrete materials. The operation of the third motor causes the auger to rotate inside one end of the slipform, squeezing the concrete at the bottom of the hopper into the inner side of the slipform, filling the entire interior of the slipform. The movement of the slipform shapes the concrete. Due to its short length and arc-shaped structure, the forming effect is better, and the pouring process is smoother and more aesthetically pleasing.

[0016] (2) The highway arch frame construction pouring equipment of the present invention, through the cooperation of the drive mechanism, enables the control mechanism and the rotation mechanism to adjust their positions as needed, so as to pour concrete at different positions. That is, through the operation of one set of first motors, the gear drives the rack to move, thereby making the support arm and the working arm slide, which is conducive to adjusting the working position of the support arm according to the slope length. Through the operation of another set of first motors, the gear and the rack move, thereby making the slide move on the support arm, so as to pour concrete in different areas, making the operation more convenient and flexible.

[0017] (3) The highway arch frame construction and pouring equipment of the present invention, through the installation of the installation mechanism, enables the vibrator inside the pouring mechanism to be well placed and placed stably and not easily fall off, so as to achieve better vibration of concrete. That is, through the installation of multiple symmetrical support rods, it is convenient to connect multiple sleeves, so that multiple sleeves are located at the center line inside the hopper, thereby facilitating the insertion and placement of the vibrator, realizing the vibration of the concrete inside the hopper, and making the concrete better discharged. After the vibrator is inserted into the sleeve, through the rotation of the screw, the screw end abuts against the side wall of the vibrator under the action of the thread, so that the vibrator is installed stably. Through the installation of the clamp, it is convenient to wrap and clamp the side wall of the vibrator, so that the vibrator is clamped stably. Through the installation of the anti-slip pad, the vibrator is not easy to loosen, and plays a role in anti-slip and anti-wear.

[0018] (4) The highway arch frame construction and pouring equipment described in this invention, through the installation of the support mechanism, facilitates the stability of the control mechanism end and the ground support, making the concrete pouring more stable. That is, through the installation of the horizontal plate, it is convenient to connect the two support feet, thereby realizing the support of the end of the support arm, making the concrete pouring stable. Through the operation of the third hydraulic cylinder, the angle of the horizontal plate is adjusted, which is beneficial to better support the support arm. Through the operation of the two fourth hydraulic cylinders, the support angle of the support feet is adjusted, making the horizontal plate support stable. Under the action of the insertion rod, the support feet are stable and not easy to slip on the ground support. Attached Figure Description

[0029] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, the highway arch frame construction pouring equipment of the present invention includes a vehicle carrier 1, a control mechanism 2 installed on the vehicle carrier 1, a drive mechanism 3 installed on the control mechanism 2, a support mechanism 7 installed on the control mechanism 2, a rotating mechanism 4 installed on the control mechanism 2, a pouring mechanism 5 installed on the rotating mechanism 4, and an installation mechanism 6 installed on the pouring mechanism 5.

[0031] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, the control mechanism 2 includes a support arm 201, which is connected to the vehicle carrier 1. A working arm 202 is rotatably connected to the top of the support arm 201. A first hydraulic cylinder 203 is rotatably connected to the bottom of one end of the working arm 202. One end of the first hydraulic cylinder 203 is rotatably connected to the top end of the working arm 202. A support arm 204 is installed on the working arm 202, and a slide block 205 is installed at one end of the support arm 204. The installation of the support arm 201 facilitates the support connection of the working arm 202. The operation of the first hydraulic cylinder 203 enables the adjustment of the elevation angle of the working arm 202, which in turn facilitates the adjustment of the angle of the support arm 204 on the working arm 202, enabling pouring work on different slopes. The installation of the slide block 205 facilitates the subsequent installation and control of the slipform 501, enabling the pouring of concrete on the slope.

[0032] Specifically, such as Figure 1 and Figure 3 As shown, the rotating mechanism 4 includes a connecting arm 401. The connecting arm 401 is installed at the bottom of the slide block 205. A second motor 402 is installed at the bottom edge of the slide block 205. The connecting arm 401 is rotatably connected to the bottom of the slide block 205 via the second motor 402. One end of the connecting arm 401 is connected to a mounting plate 404. A second hydraulic cylinder 403 is connected between the mounting plate 404 and the connecting arm 401. The mounting plate 404 is longitudinally slidably connected to one end of the connecting arm 401 via the second hydraulic cylinder 403. The installation of the connecting arm 401 facilitates the connection of the mounting plate 404. The connection of the mounting plate 404 facilitates the installation of the slipform 501. The operation of the second hydraulic cylinder 403 allows for height adjustment of the slipform 501 to achieve concrete pouring. The installation of the second motor 402 allows for control of the rotation angle of the connecting arm 401, enabling the slipform 501 to perform arc-shaped pouring, making operation more convenient.

[0033] Specifically, such as Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, the casting mechanism 5 includes a mounting frame 503. The mounting frame 503 is mounted on one side of the mounting plate 404. A sliding mold 501 is mounted on the bottom of the mounting frame 503. The sliding mold 501 has arc-shaped structures on both sides. A hopper 502 is vertically connected to one end of the top of the sliding mold 501. The bottom of the hopper 502 extends to the inner side of the bottom of the sliding mold 501. A third motor 504 is detachably connected to the outer side of one end of the sliding mold 501. A screw rod 505 is rotatably connected to the inside of one end of the sliding mold 501. The output shaft of the third motor 504 is connected to one end of the screw rod 505. The screw rod 505 is positioned... At the bottom of the hopper 502, the installation of the mounting bracket 503 facilitates the connection of the slip mold 501. The installation of the hopper 502 facilitates the storage of concrete materials. Through the operation of the third motor 504, the screw rod 505 rotates inside one end of the slip mold 501, causing the concrete at the bottom of the hopper 502 to be squeezed into the inner side of the slip mold 501, filling the entire interior of the slip mold 501. The movement of the slip mold 501 shapes the concrete. Because the slip mold 501 is short and has an arc-shaped structure, the shaping effect is better, and the pouring is smoother and more aesthetically pleasing.

[0034] Specifically, such as Figure 2 and Figure 3As shown, the drive mechanism 3 includes racks 302. Two parallel and symmetrical racks 302 are installed at the top edge of the support arm 204. The support arm 204 is slidably connected to the slide 205 and the working arm 202. Two gears 303 are rotatably connected inside one end of the slide 205 and the working arm 202, respectively. The two gears 303 mesh with the two racks 302. Two first motors 301 are detachably installed at the top of one end of the slide 205 and the working arm 202, respectively. The output shafts of the first motors 301 are respectively... Connected to gear 303, the operation of one set of first motors 301 causes gear 303 to drive rack 302 to move, thereby allowing the support arm 204 to slide relative to the working arm 202. This facilitates adjustment of the working position of the support arm 204 according to the slope length. The operation of the other set of first motors 301 causes gear 303 and rack 302 to move, thereby allowing slide 205 to move on the support arm 204, enabling concrete pouring in different areas, making the operation more convenient and flexible.

[0035] Specifically, such as Figure 5 and Figure 7 As shown, the installation mechanism 6 includes a retainer 601. Multiple retainers 601 are longitudinally and equidistantly distributed at the center of the hopper 502. Each retainer 601 has a circular structure. Two support rods 602 are installed on the outer sides of the retainers 601. The support rods 602 are perpendicularly connected to the inner wall of the hopper 502. The installation of multiple symmetrical support rods 602 facilitates the connection of the multiple retainers 601, positioning them at the centerline inside the hopper 502. This allows for easy insertion and placement of the vibrator, enabling vibration of the concrete inside the hopper 502 and better concrete discharge.

[0036] Specifically, such as Figure 7 As shown, one of the sleeves 601 has a screw 603 vertically threaded to its side wall. The screw 603 has a cylindrical "T"-shaped structure. One end of the screw 603 extends into the inside of the sleeve 601. After the vibrating rod is inserted into the sleeve 601, the rotation of the screw 603 causes one end of the screw 603 to abut against the side wall of the vibrating rod under the action of the thread, thus stabilizing the installation of the vibrating rod.

[0037] Specifically, such as Figure 7 and Figure 8As shown, a clamping plate 604 is slidably connected inside the side wall of the sleeve 601. The clamping plate 604 has an arc-shaped structure, with one side extending to the outside. An anti-slip pad 605 is installed on one side of the clamping plate 604. One end of the screw 603 is rotatably connected to the center of the other side of the clamping plate 604. The installation of the clamping plate 604 facilitates the wrapping and clamping of the side wall of the vibrator, making the vibrator stable. The installation of the anti-slip pad 605 makes the vibrator less prone to loosening, playing a role in anti-slip and anti-wear.

[0038] Specifically, such as Figure 1 and Figure 6 As shown, the support mechanism 7 includes a horizontal plate 701. The horizontal plate 701 is rotatably connected to the end of the support arm 204. The horizontal plate 701 is perpendicular to the support arm 204. A third hydraulic cylinder 702 is rotatably connected to the bottom side of the support arm 204. One end of the third hydraulic cylinder 702 is rotatably connected to the center of one side of the horizontal plate 701. Support legs 704 are rotatably connected to both ends of the horizontal plate 701. Insert rods 705 are respectively installed at the bottom of the two support legs 704. Fourth hydraulic cylinders 703 are rotatably connected to the bottom of both ends of the horizontal plate 701. One end of each of the two fourth hydraulic cylinders 703 is connected to one of the two support legs 701. The foot 704 is rotatably connected on one side. The installation of the horizontal plate 701 facilitates the connection of the two support feet 704, thereby supporting the end of the support arm 204 and stabilizing the concrete pouring. The operation of the third hydraulic cylinder 702 allows for the adjustment of the angle of the horizontal plate 701, which facilitates better support of the support arm 204. The operation of the two fourth hydraulic cylinders 703 allows for the adjustment of the support angle of the support feet 704, making the horizontal plate 701 stable. Under the action of the insertion rod 705, the support feet 704 are stably supported on the ground and are not prone to slippage.

[0039] In use, this invention firstly facilitates the support and connection of the working arm 202 through the installation of the support arm 201. The operation of the first hydraulic cylinder 203 allows for adjustment of the elevation angle of the working arm 202, which in turn allows for adjustment of the angle of the support arm 204 on the working arm 202, enabling concrete pouring at different slopes. The installation of the sliding block 205 facilitates the installation and control of the sliding mold 501, enabling concrete pouring and shaping on the slope. The installation of the connecting arm 401 facilitates the connection of the mounting plate 404, which in turn facilitates the installation of the sliding mold 501. The operation of the second hydraulic cylinder 403 allows for height adjustment of the sliding mold 501, enabling the pouring operation. The installation of the second motor 402 enables control of the connecting arm 401. The rotation angle control enables the slipform 501 to pour concrete inside the arc-shaped groove, making operation more convenient. The installation of the mounting bracket 503 facilitates the connection of the slipform 501, and the installation of the hopper 502 facilitates the storage of concrete materials. The operation of the third motor 504 causes the auger 505 to rotate inside one end of the slipform 501, squeezing the concrete at the bottom of the hopper 502 into the inner side of the slipform 501, filling the entire interior of the slipform 501. The movement of the slipform 501 shapes the concrete. Due to the short and arc-shaped structure of the slipform 501, the shaping effect is better, and the pouring is smoother and more aesthetically pleasing. The operation of one set of first motors 301 causes the gear 303 to drive the rack 302 to move, thereby moving the support arm 20... 4. The sliding of the working arm 202 facilitates the adjustment of the working position of the support arm 204 according to the slope length. Through the operation of another set of first motors 301, the gears 303 and racks 302 move, thereby moving the slide block 205 on the support arm 204 to achieve pouring in different areas, making the operation more convenient and flexible. The installation of multiple symmetrical support rods 602 facilitates the connection of multiple sleeves 601, so that the multiple sleeves 601 are located at the center line inside the hopper 502, which facilitates the insertion and placement of the vibrator, realizing the vibration of the concrete inside the hopper 502, and making the concrete better discharged. After the vibrator is inserted into the sleeve 601, the rotation of the screw 603, under the action of the thread, causes one end of the screw 603 to connect with the vibrator. The sidewalls of the vibrator abut against each other, ensuring stable installation. The clamping plate 604 helps to wrap and hold the sidewalls of the vibrator, ensuring stable clamping. The anti-slip pad 605 prevents the vibrator from loosening, providing anti-slip and anti-wear protection. The horizontal plate 701 facilitates the connection of the two support feet 704, thereby supporting the end of the support arm 204 and ensuring stability during pouring. The operation of the third hydraulic cylinder 702 allows for angle adjustment of the horizontal plate 701, providing better support for the support arm 204. The operation of the two fourth hydraulic cylinders 703 allows for angle adjustment of the support feet 704, ensuring stable support from the horizontal plate 701. Under the action of the insertion rod 705, the support feet 704 are stably supported on the ground and do not slip.
