[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0031] In the description of the present invention, it should be noted that the terms "upper", "lower", "inside", "outside", "front end", "rear end", "two ends", "one end", "the other end" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0032] The utility model is a road shoulder intelligent slipform machine, which is used for constructing road shoulder, guardrail base and other road surface structures. In the following description, the forward direction of the machine when working is regarded as the front.

[0033] like Figure 1 , Figure 2As shown, the slipform machine mainly includes a frame 2, a lower material bin 3 and a slipform forming plate 4. A walking wheel 1 is arranged at the lower part of the frame 2, and a driving mechanism is arranged accordingly, and the walking wheel 1 is used to drive the whole machine to move. The lower material bin 3 and the slipform forming plate 4 are arranged on the frame 2. The lower material bin 3 is used for laying concrete materials, and then the slipform forming plate 4 is used to form the structure of the shoulder or guardrail base. The lower material bin 3 is fixedly arranged at the front part of the frame 2 and arranged upward. The slipform forming plate 4 is located below the lower material bin 3 and arranged relatively backward. The discharge port of the lower material bin 3 is in a lower position, and the lower material bin 3 extends downward as a whole, and the discharge port at its lower end is basically maintained in the same height area as the slipform forming plate 4. The arrangement of the lower material bin 3 and the slipform forming plate 4 can enable the concrete material to enter the area of ​​the slipform forming plate 4 from the lower end of the lower material bin 3.

[0034] The cross section of the slipform forming plate 4 is in the shape of a shoulder or a guardrail base, and is generally in the shape of a convex letter. After the concrete material falls, it enters the slipform forming plate 4 and forms a preset shape structure under the effect of the slipform forming plate 4 as a mold. Figure 3 and Figure 4 Shown in the figure is a schematic diagram from the bottom view, showing the structure of the slipformed plate. Figure 5 and Figure 6 The structure of the slipformed plate can also be seen.

[0035] In order to facilitate the concrete material to enter the slipform forming plate 4 better, a feed port is set at the front end of the slipform forming plate 4. The feed port here opens obliquely upward, which can make it easier for the concrete material to flow into the main part of the slipform forming plate 4. Figure 5 , Figure 6 shown.

[0036] like Figure 2 As shown, the machine is provided with a plurality of vibrating rods 5 in the unloading bin 3, which are used to vibrate the concrete material in the unloading bin 3. In a specific implementation, the vibrating rods 5 are divided into a forming vibrating rod and a unloading vibrating rod according to their functions. Among them, the main function of the forming vibrating rod is to vibrate the concrete material to improve the performance of the concrete and enable the concrete to fully exert its performance. The unloading vibrating rod is used to promote the falling of the concrete material in the unloading bin 3 and prevent the concrete material in the unloading bin 3 from condensing. Further, specifically, the height of the forming vibrating rod is less than the height of the unloading vibrating rod. The installation height of the forming vibrating rod is relatively low, and it is used to vibrate the concrete material that will enter the slipform forming plate 4. The installation height of the unloading vibrating rod is relatively high, and is located in the middle and upper part of the unloading bin 3. The vibrating rod is a high-frequency vibrating rod, and the main function of the vibrating rod is material molding, and unloading is an auxiliary function. Therefore, the number of forming vibrating rods is generally greater than the number of unloading vibrating rods. Figure 2 It can be seen that the vibrating rod 5 is installed at different heights.

[0037] In the present utility model, slurry guard plates 6 can usually be provided on both sides of the slipform forming plate 4, and the slurry guard plates 6 can play a role in preventing concrete from flowing out to the outside. The height of the slurry guard plates 6 can be raised and lowered. Specifically, the slurry guard plates 6 are installed on the frame 2 through hydraulic cylinders, and the height is adjusted by the hydraulic cylinders. Here, the fixed end of the hydraulic cylinder is fixed on the frame 2, and the movable telescopic end faces downward and is connected to the slurry guard plates 6. The slurry guard plates cooperate with the slipform forming plate to realize one-time forming of the shoulder. When the guardrail base is constructed, the one-time forming of the guardrail base is realized. Specifically, Figure 5 shown.

[0038] In the present invention, preferably, a screw conveying auger 7 can be arranged in the lower material bin 3. In particular, when the lower material bin 3 is long, a screw conveying auger 7 needs to be arranged. Concrete material is injected into the lower material bin 3 from one end of the lower material bin 3, and the screw conveying auger 7 can convey the concrete material from one end of the lower material bin 3 to the other end.

[0039] During the implementation of the utility model, a running wheel 1 is provided on the frame 2 for longitudinal walking. The preferred arrangement is to provide three running wheels 1. Among them, one running wheel 1 is provided on the front side of the frame 2, and two running wheels 1 are provided on both sides of the rear side of the frame 2. The three running wheels 1 are arranged in a triangle. The three running wheels 1 are mounted on the frame 2 through the lifting legs 8, and then a hydraulic cylinder is provided on the side of the lifting legs 8, and the lifting and lowering of the frame 2 relative to the running wheels 1 is driven by the hydraulic cylinder. Here, the lifting legs 8 are equivalent to providing a guide cylinder for the lifting and lowering between the running wheels 1 and the frame 2.

[0040] In a specific implementation, rubber tires are preferably used for the three running wheels 1, and the running wheels 1 are driven to rotate by a motor in cooperation with a reducer. The running wheels 1 can be raised and lowered and turned.

[0041] The slipform machine can use GPS positioning and also use laser positioning. GPS positioning is used to locate the latitude and longitude position, and laser positioning is used to locate the elevation. The GPS locator is installed on the upper end of the lifting leg 8 of the walking wheel 1. The laser receiver 10 is also installed on the upper end of the lifting leg 8 of the walking wheel 1. When in use, a laser transmitter is set on the road surface to cooperate with the laser receiver 10 for elevation positioning. Specifically, Figure 1 , Figure 2 shown.

[0042] The machine uses RTK control system for positioning. The RTK control system uses a GPS as a base station to locate the longitude and latitude coordinates on both sides of the rear wheels, and a laser transmitter as an elevation reference to control the elevation of the laser receivers on the left and right sides. During operation, the GPS base station and laser transmitter are set up, and the longitude and latitude coordinates and elevation of the construction are input into the control system, and then the controller calculates and sends the control signal to the hydraulic solenoid valve to control the lifting and lowering of the front and rear wheels.

[0043] The slipform machine is provided with components for determining the travel trajectory. Specifically, a steering sensor 11 is provided on one side of the frame 2 to control the travel trajectory of the machine. When working, the slide bar of the steering sensor 11 is attached to a preset steel wire rope. Before construction, a steel wire rope is pre-set on the road surface along the extension direction of the road surface. Under normal circumstances, the slide bar of the steering sensor 11 is attached to the steel wire rope. If the machine deviates or needs to turn, after the deviation is detected, a signal is given to the control system to control the solenoid valve for steering. The steering sensor 11 is installed on the side of the frame 2 with the isomorphic suspension rod. Specifically, Figure 1 , Figure 2 shown.

[0044] The utility model can also set a cleaning component on the frame 2, so that the machine can be cleaned in time after the construction is completed. The cleaning component includes a water pump, a water tank and a flushing nozzle. After the water pump draws water from the water tank, the machine is flushed through the flushing nozzle.

[0045] The utility model sets a generator set and a hydraulic pump station on the frame 2. The generator set provides power for the machine, usually using a diesel generator. The hydraulic pump station provides the hydraulic power required by each hydraulic component, and the hydraulic system pipeline has multiple solenoid valves to realize hydraulic control.

[0046] like Figure 1 , Figure 2 As shown, standing platforms 12 are provided at the front and rear sides of the frame 2 , and workers can work on the standing platforms 12 when necessary.

[0047] The utility model can be applicable to the construction of road shoulders and guardrail bases, can realize one-time slip-form forming construction of concrete materials, realize intelligent and mechanized construction of road shoulders and guardrail bases, and improve construction efficiency and construction quality.
