When used with a common forklift, it can meet the actual work needs and provide convenience for the installation of the sound barrier. The sling is hung before the upper limit support of the support rod. The end of the sling is firmly connected to the sound barrier through a suction cup. The forklift is operated to make the sound barrier reach the installation height. The length of the anchor rope is adjusted so that when the forklift lifting mechanism reaches the highest, the hoisting height of the sound barrier meets the installation requirements, making the installation of the bridge engineering sound barrier convenient and safe, saving time and effort, and avoiding damage to the completed road surface or damage to the bridge structure.

[0028] Example

[0029] Combination Figure 1-Figure 4 As shown, a device for installing a viaduct sound barrier is implemented, including a frame, a driving mechanism, a power supply mechanism, a lifting mechanism and a walking mechanism; the frame includes a first support rod 1 and a second support rod 2, the bottom end of the first support rod 1 is movably connected to the top end of the second support rod 2, and the first support rod 1 and the second support rod 2 constitute a telescopic rod, and the height of the frame is adjusted by the telescopic action of the telescopic rod; the driving mechanism and the power supply mechanism are installed at the bottom of the frame; the lifting mechanism is installed at the top of the frame, and the lifting mechanism is electrically connected to the power supply mechanism; the power supply mechanism provides power for the driving mechanism and the lifting mechanism; a control switch 7 is also installed on the frame, and the control switch 7 controls the action of the driving mechanism and the lifting mechanism, and the connection between the control switch 7 and the driving mechanism and the lifting mechanism can be wired or wireless, so as to realize control; a walking mechanism is provided at the bottom of the frame. Among them, the driving mechanism adopts a DC motor 15 with a power of 500W, and the DC motor 15 provides power for the walking mechanism. The power supply mechanism uses a battery 16 with a voltage of 48V. Two groups of batteries 16 are provided. The batteries 16 provide power for the DC motor 15 and the electric hoist 8.

[0030] Specifically, at least four first support rods 1 are provided, and a scaffolding board 4 is installed between the four first support rods 1, and the scaffolding board 4 is perpendicular to the four first support rods 1; each first support rod 1 adopts a steel pipe with a nominal diameter of 32mm and a wall thickness of 1.8mm, and the four first support rods 1 are arranged parallel to each other. A fence 6 is provided outside the four first support rods 1, and the fence 6 is located at the upper end of the scaffolding board 4. The provision of the fence 6 can improve the installation stability between the four first support rods 1 on the one hand, and ensure the range of motion of the lifting mechanism on the other hand. Specifically, the lifting mechanism adopts an electric hoist 8, which is an existing device. A first cross bar 3 is installed on the top of the first support rod 1. One end of the electric hoist 8 is fixed on the first cross bar 3, and the other end is electrically connected to the battery 16 through the wire 17. The electric hoist 8 is also hoisted with a screen body through a steel wire rope, so that when the electric hoist 8 is started, the screen body can be lifted and lowered under its drive.

[0031] Similarly, in order to adapt to the first support rod 1, at least four second support rods 2 are provided, each second support rod 2 is connected to a corresponding first support rod 1, and a counterweight frame 5 is installed between two adjacent second support rods 2, wherein the counterweight frame 5 is arranged in parallel with the scaffolding board 4. The control switch 7 is installed on the second support rod 2, and the control switch 7 is arranged above the counterweight frame 5, wherein the control switch 7 is provided with a switching button. The telescopic operation of the telescopic rod composed of the first support rod 1 and the second support rod 2 can be controlled by manual adjustment, or the existing electric drive method can be used to realize the telescopic operation; the switching button of the control switch 7 can control the switching of the action of the electric hoist 8 and the walking mechanism, and the control program of the control switch 7 is the existing program. The second support rod 2 adopts a steel pipe with a nominal diameter of 40mm and a wall thickness of 2.0mm.

[0032] The walking mechanism includes a front wheel 13 and a rear wheel 14, both of which are installed at the bottom of the second support rod 2, and four driven wheels 12 are also arranged on the second support rod 2 connected to the front wheel 13, a second cross bar 9 is arranged between two adjacent second support rods 2, a driving wheel 11 is arranged on the second cross bar 9, and the driving wheel 11 and the four driven wheels 12 are externally meshed with the same chain 10. The DC motor 15 is specifically installed on the second cross bar 9, and the output shaft of the DC motor 15 is connected to the driving wheel 11. When the DC motor 15 is started, the driving wheel 11 connected thereto can be driven to rotate, and the driving wheel 11 rotates to drive the chain 10 and the other four driven wheels 12 to rotate, thereby making the front wheel 13 walk, wherein the bottom of the chain 10 and the bottom of the front wheel 13 are located on the same horizontal plane, so that when the chain 10 rotates, the front wheel 13 can be driven to walk on the same horizontal plane. When the front wheel 13 walks, it drives the rear wheel 14 to walk. There are two rear wheels 14, each of which is mounted at the bottom of a second support rod 2, and each rear wheel 14 is provided with a flat washer 18, which plays the role of filling uneven surfaces and reducing wear. The specific connection structure between the front wheel 13 and the first support rod 1, and the connection structure between the rear wheel 14 and the second support rod 2 are existing means, and the front wheel 13 and the rear wheel 14 can be mounted at the lower end of the second support rod 2 by a movable shaft connection.

[0033] The actual operating principle of this device is: place the screen of the sound barrier to be placed on the outside of the frame, and the preferred placement position is on the same side of the electric hoist 8 and the flat washer 18. The device first assembles the frame on site, and the battery 16 provides power to the DC motor 15 and the electric hoist 8. After the assembly is completed, the walking mechanism and the lifting mechanism are switched through the control switch 7, and then the walking of the frame and the lifting action of the electric hoist 8 are debugged. After they are correct, they are transported to the working surface, where the height difference between the front wheel 13 and the rear wheel 14 is set according to the flatness of the specific working surface. For example, when the height of the rear end of the working surface is higher than that of the front end, the height of the rear wheel 14 on the rear end working surface is lower than that of the front wheel 13 on the front end working surface. Figure 3 There is a height difference between the front wheel 13 and the rear wheel 14, but if the working surface is flat, the front wheel 13 and the rear wheel 14 can be manually operated to be at the same level, such as by increasing the length of the second support rod 2 connected to the rear wheel 14. After debugging is correct, the control switch 7 is used to control the electric hoist 8 to lift the screen; after the operation is completed, the control switch 7 is switched to control the DC motor to start, so that the walking mechanism can walk.

[0034] The above is only an implementation method of the utility model, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
