Detailed Implementation

[0025] Example 1

[0026] like Figure 1-6 As shown, this concrete pushing device suitable for use under cable trays includes a movable frame 1, with one side open. A telescopic device 2 with a telescopic effect is fixedly installed on the inner wall of the movable frame 1. A pushing plate 3 for pushing concrete is fixedly installed at the telescopic end of the telescopic device 2. Several moving wheels 4 are fixedly installed at the lower part of the movable frame 1. A vertical column 5 is fixedly installed at the upper part of the movable frame 1. A cleaning strip 6 for cleaning one side of the pushing plate 3 is provided on one side of the vertical column 5. A drive unit 7 for driving the cleaning strip 6 to move up and down is provided at the upper part of the vertical column 5. The system includes a drive motor 8 fixedly installed on the upper end of the vertical column 5, a sliding block 9 slidably connected to one side of the vertical column 5, a connecting frame 10 between the sliding block 9 and the cleaning strip 6, a sliding groove 11 adapted to the sliding block 9 on one side of the vertical column 5, a drive screw 12 rotatably connected to the output end of the drive motor 8 in the sliding groove 11, the drive screw 12 passing through the sliding block 9 and threadedly connected to it, a mounting frame 23 fixedly installed on one side of the movable frame 1, a remote controller 24 for controlling the telescopic device 2 on the upper end of the mounting frame 23, and a push handle 26 fixedly installed on one side of the movable frame 1.

[0027] In this embodiment, when concrete needs to be poured for the cable tray, the cable tray is supported and fixed. When it is necessary to push the concrete to the lower position of the cable tray, the concrete pushing device is pushed to the side of the cable tray by pushing the handrail 26 and the moving wheel 4. The concrete is placed on the side of the cable tray. The telescopic device 2 is activated by the remote controller 24. The telescopic end of the telescopic device 2 drives the pushing plate 3 to move, pushing the concrete located on the side of the cable tray to the lower position of the cable tray. Then the telescopic device 2 drives the pushing plate 3 to return to its original position. The above steps are performed in sequence to improve the efficiency of pouring concrete under the cable tray. When a large amount of concrete adheres to the pushing side of the pushing plate 3, the drive motor 8 is activated. The output end of the drive motor 8 drives the drive screw 12 to rotate. When the drive screw 12 rotates, it drives the sliding block 9 to slide in the sliding groove 11. The sliding block 9 drives the connecting frame 10 to move. The connecting frame 10 drives the cleaning strip 6 to move down. The cleaning strip 6 is adapted to the side of the pushing plate 3 to scrape off the concrete adhered to the side of the pushing plate 3, preventing a large amount of concrete from adhering to the side of the pushing plate 3, increasing the weight of the overall device, and improving the practicality of the device.

[0028] Example 2

[0029] Please see Figures 2-6 In this embodiment, the concrete pushing device applicable to the bridge frame also includes: a first plug-in block 13 is fixedly installed on the side of the pushing plate 3 near the telescopic device 2; a first plug-in groove 14 adapted to the first plug-in block 13 is opened at the telescopic end of the telescopic device 2; a T-shaped limiting rod 15 is passed through the side of the telescopic end of the telescopic device 2; a limiting hole 16 adapted to the end of the limiting rod 15 is opened on the side of the first plug-in block 13; a spring 17 is fixedly installed between one side of the limiting rod 15 and the side of the telescopic end of the telescopic device 2; a second plug-in block 18 is fixedly installed on the upper part of the cleaning strip 6; a second plug-in groove 19 adapted to the second plug-in block 18 is opened at the lower end of the connecting frame 10; and a first fixing bolt 20 with one end threadedly connected to the side of the second plug-in block 18 is passed through the side of the lower end of the connecting frame 10.

[0030] In this embodiment, when installing the push plate 3, the telescopic end of the telescopic device 2 extends out of the moving frame 1, and the limiting rod 15 is pulled away from the first plug-in block 13. The limiting rod 15 drives the spring 17 to stretch, inserting the first plug-in block 13 on the side of the push plate 3 into the first plug-in groove 14, and aligning the position of the limiting hole 16 with the end of the limiting rod 15. When the limiting rod 15 is released, the tension of the spring 17 pulls the limiting rod 15 towards the first plug-in block 13, and one end of the limiting rod 15 is inserted into the limiting hole 16, thus completing the installation of the push plate 3. This facilitates the installation or later replacement of the push plate 3. When installing the cleaning strip 6, the second plug-in block 18 on the cleaning strip 6 is inserted into the second plug-in groove 19, and one end of the first fixing bolt 20 passes through the connecting frame 10. The end of the first fixing bolt 20 is threadedly connected to the second plug-in block 18, thus completing the installation of the cleaning strip 6. This facilitates the installation or later replacement of the cleaning strip 6.

[0031] Example 3

[0032] like Figures 1-3 As shown, this embodiment of the concrete pushing device under the bridge also includes: at least two telescopic devices 2, one end of which is fixedly installed with a mounting base 21, a second fixing bolt 22 with one end threadedly connected to the mounting base 21 passing through one side of the movable frame 1, and a baffle 25 fixedly installed on the upper part of the movable frame 1.

[0033] In this embodiment, there are two telescopic devices 2 to improve the stability when pushing the push plate 3. When installing the telescopic device 2, one side of the mounting base 21 abuts against the inner wall of the movable frame 1. One end of the second fixing bolt 22 passes through the movable frame 1 and its end is threaded to the side of the mounting base 21, which facilitates the installation or later replacement of the telescopic device 2. A chemical power source for power supply can be installed in the baffle 25. A counterweight can also be placed in the baffle 25 to ensure the stability of the push plate 3 when pushing concrete.

They are mature technologies and have been fully disclosed, so they will not be repeated in the instruction manual. All of the electrical products mentioned above are equipped with power cords, and they are electrically connected to the remote controller 24 and the 220V phase voltage (or chemical power source) through the power cords.
