[0035] like Figure 1 The present invention provides a device for forming a road retaining wall in an open-pit mine, comprising a three-sided pressing and forming mechanism 1, which applies pressure from the top and both sides according to the characteristics of the road in the mine to form a retaining wall with a trapezoidal cross-section, thereby improving the stability of the retaining wall; an alternating driving mechanism 2, wherein the three-sided pressing and forming mechanism 1 is connected to the alternating driving mechanism 2, and has an alternating and continuous movement effect, thereby producing a continuous pressing and forming effect, thereby improving the production efficiency; a construction vehicle 3, wherein a retracting and releasing mechanism 4 is provided on the construction vehicle 3, wherein the alternating driving mechanism 2 is connected to the retracting and releasing mechanism 4, and is used to control the retracting and releasing of the overall production device, so that the device is stored in the vehicle, or extended out of the vehicle body to produce the retaining wall, wherein the construction vehicle 3 is a flatbed vehicle, and no baffle is provided on the construction vehicle 3, thereby providing a wider movement space for the production device.

[0036] like Figure 6-8 The three-sided pressing and forming mechanism 1 includes a pressing shell 5, a top pressure plate 6, a side pressure plate 7, a side slide plate 8, a linkage assembly 9 and a pressing hydraulic cylinder 10. The side slide plates 8 are provided with two, and are laterally slidably arranged on both sides of the pressing shell 5. The top pressure plate 6 is connected to a vertical slide bar 11. The pressing hydraulic cylinder 10 is arranged in the pressing shell 5. The pressing hydraulic cylinder 10 is connected to the vertical slide bar 11. The linkage assembly 9 includes a linkage block 12 and a linkage rod 13. The linkage block 12 is arranged on the vertical slide bar 11. The linkage rod 13 is provided with two, which are hinged on both sides of the linkage block 12. The other end of the linkage rod 13 is hinged to the side slide plate 8.

[0037] When the pressing hydraulic cylinder 10 pushes the vertical slide bar 11 to slide, the side slide plate 8 is pulled to slide through the linkage rod 13, thereby generating a synchronous movement effect.

[0038] The pressing shell 5 is provided with an opening, the vertical sliding rod 11 extends out of the pressing shell 5 , the side sliding plate 8 extends out of the pressing shell 5 , the side pressing plate 7 is connected to the side sliding plate 8 , and the top pressing plate 6 and the side pressing plate 7 are located outside the pressing shell 5 .

[0039] like Figure 2-5In order to achieve the effect of continuous pressing, an alternating driving mechanism 2 is set, including a driving shell 14, two traveling arms 15 and 16 that can move alternately, and a traveling component 17 that drives the traveling arm 15 and the traveling arm 2 to move. The traveling component 17 includes an upper gear 18, a middle gear 19 and a lower gear 20 arranged above, middle and below, and the three are meshed and connected in pairs to form a linkage, that is, the upper gear 18 and the lower gear 20 have the same rotation direction. The traveling component 17 is provided with two groups, and inner support plates 21 are provided on both sides of the driving shell 14. The traveling component 17 is symmetrically arranged on the inner support plates 21 on both sides, and a connecting shaft 22 is provided between the two middle gears 19 on both sides, so that the traveling components 17 on both sides can operate synchronously, and the connecting shaft 22 is connected to the motor and the gear set.

[0040] The upper gear 18 and the lower gear 20 are both provided with a connector 23 at the same position, and the connector 23 is eccentrically arranged, and the traveling arm 15 and the traveling arm 2 16 are respectively rotatably connected to the connectors 23 of the two traveling components 17. When the upper gear 18 and the lower gear 20 rotate, the traveling arm can be driven to move forward continuously.

[0041] In order to make the traveling arm 15 and the traveling arm 2 16 move alternately, the connecting heads 23 on both sides are symmetrically arranged, that is, the traveling arm 15 and the traveling arm 2 16 are arranged one in front of the other; therefore, when the connecting shaft 22 rotates, it drives the middle gears 19 on both sides to rotate synchronously, and the middle gear 19 drives the upper gear 18 and the lower gear 20 to rotate in the same direction. Since the connection positions of the traveling arm 15 and the traveling arm 2 16 and the two traveling components 17 are one in front of the other, an alternating movement effect is generated.

[0042] The traveling arm 1 15 and the traveling arm 2 16 are both provided with a three-sided pressing and forming mechanism 1 .

[0043] like Fig. 9 In order to improve the pressing effect, a tamping device 24 is provided on the side pressure plate 7, and the tamping device 24 includes a tamping plate 25, a plate frame 26, a swing hammer 27, a swing rod 28, a buffer spring 29 and a vibrating body 30. An opening is provided on the side pressure plate 7, and the tamping plate 25 is embedded in the side pressure plate 7. The plate frame 26 is provided on the tamping plate 25, and the swing rod 28 is hinged on the plate frame 26 and connected to the vibrating body 30. The swing hammer 27 is rotatably provided on the vibrating body 30, and a motor connected to the swing hammer 27 is provided in the vibrating body 30. A buffer spring 29 is connected between the plate frame 26 and the vibrating body 30.

[0044] When the swing hammer 27 rotates, vibration is generated, and the swing rod 28 drives the vibrating body 30 to swing, and the buffer spring 29 buffers the lateral vibration of the swing hammer 27, while retaining the longitudinal vibration for vibration compaction of the retaining wall.

[0045] The side pressure plate 7 is provided with a connecting frame 31 , and the connecting frame 31 is provided with a telescopic rod 32 . The telescopic rod 32 is connected to the tamping plate 25 .

[0046] like Fig.10 The retractable mechanism 4 includes a support column 33, an active folding rod 34, a driven folding rod 35 and a retractable hydraulic cylinder 36. The support column is fixedly arranged on the construction vehicle 3. The active folding rod 34 and the driven folding rod 35 are hinged on the support column 33, and the active folding rod 34 and the driven folding rod 35 are parallel. A connecting plate 37 is provided on the driving housing 14. The active folding rod 34, the driven folding rod 35 and the connecting plate 37 are hingedly connected. The retractable hydraulic cylinder 36 is hingedly arranged on the construction vehicle 3, and the telescopic end of the retractable hydraulic cylinder 36 is hinged to the active folding rod 34.

[0047] The retractable hydraulic cylinder 36 is started to push the active folding rod 34 to rotate, and the driven folding rod 35 rotates synchronously, thereby driving the alternating drive mechanism 2 to be retracted onto the construction vehicle 3, or released from the construction vehicle 3 to make a retaining wall, and the alternating drive mechanism 2 can be controlled to always maintain horizontal movement.

[0048] The side pressure plates 7 are inclined, and the top pressure plate 6, the two side pressure plates 7 and the ground form four sides of a trapezoid, which can be pressed into a retaining wall with a trapezoidal cross section.

[0049] A transverse slide bar 38 is arranged in the pressing shell 5 , and an opening is arranged on the side slide plate 8 , which is slidably connected to the transverse slide bar 38 .

[0050] Swing weights 27 are provided on both sides of the vibrating body 30 , and the swing weights 27 and the vibrating body 30 are eccentrically connected.

[0051] When in use, the construction vehicle 3 drives to the construction site, starts the retractable hydraulic cylinder 36 to push the active folding rod 34 to rotate, and at the same time the driven folding rod 35 rotates synchronously, thereby driving the alternating drive mechanism 2 to extend out of the construction vehicle 3 to manufacture the retaining wall.

[0052] The pressing hydraulic cylinder 10 is started to push the vertical slide bar 11 to slide, and the side slide plate 8 is pulled to slide by the linkage rod 13, so that the top pressure plate 6 and the side pressure plate 7 generate extrusion movement, and the soil and rocks are extruded and formed, and initially extruded into a retaining wall with a trapezoidal cross section. Since the slopes on both sides of the retaining wall are prone to falling off, the tamping device 24 is started to compact the slope surface, and the motor is started to drive the swing hammer 27 to rotate. Since the swing hammer 27 is eccentrically set, it will vibrate in all directions of rotation. Since the swing rod 28 drives the vibrating body 30 to swing, and is buffered by the buffer spring 29, the lateral vibration of the swing hammer 27 is buffered, and the longitudinal vibration force acts on the soil and rocks through the tamping plate 25 to achieve a compaction effect. While the tamping plate 25 vibrates longitudinally, the telescopic rod 32 performs a retracting and extending movement.

[0053] The motor in the alternating drive mechanism 2 is controlled to start, driving the connecting shaft 22 to rotate, driving the two middle gears 19 to rotate at the same time, and then the upper gear 18 and the lower gear 20 rotate in the same direction, and the upper gear 18 and the lower gear 20 drive the traveling arm to move. Since the traveling arm 15 and the traveling arm 2 16 are arranged one in front of the other, the two travel while alternating. As the construction vehicle 3 moves, the two three-sided pressing and forming mechanisms 1 achieve the effect of continuously making a retaining wall.
