Technical Field
[0001] The invention relates to the technical field of building construction equipment, in particular to an automatic vibrating device for pier column pile foundation concrete. Background Art
[0002] At present, for the construction of civil infrastructure, piers are generally constructed by the formwork method. For mountain road bridges, due to the terrain, some pile foundations need to be constructed by manually excavated piles. During the construction of piers and manually excavated piles, it is necessary to manually go down to the bottom of the hole or the bottom of the formwork to pour concrete and vibrate.
[0003] Casting piers and manually excavating bored piles are both considered high-altitude operations.
[0004] Lowering the string barrel can effectively prevent concrete segregation caused by concrete falling from a height, but the loading and unloading and lifting of the string barrel must be done manually, which has high labor intensity and low work efficiency.
[0005] The vibration of concrete requires workers to go down to the bottom of the piers and pile foundations to carry out the work, which is labor-intensive and dangerous. Summary of the invention
[0006] The technical problem to be solved by the present invention is to overcome the above difficulties and provide an automatic vibrating device for pier pile foundation concrete, which reduces manual participation in the loading and unloading, lifting of string tubes and vibration of concrete, reduces the labor intensity and danger of workers and improves work efficiency.

[0008] As an improvement, the telescopic string tube includes a plurality of mutually connected string tubes.
[0009] As an improvement, an annular protrusion 1 is provided on the outer side of the bottom of the string tube and is arranged around the string tube, and an annular protrusion 2 matching with the annular protrusion 1 is provided on the inner side of the top of the string tube.
[0010] As an improvement, the hydraulic telescopic device is a hydraulic cylinder, and the hydraulic cylinders are symmetrically arranged.
[0011] As an improvement, a distance measuring device is provided at the bottom of the working platform.
[0012] Compared with the prior art, the advantages of the present invention are: the string tube can guide the concrete to prevent the concrete from falling directly from a high place and causing concrete segregation; the telescopic string tube is formed by a plurality of string tubes connected in sequence, and can be raised with the lifting of the working platform, thereby reducing manual participation, reducing the labor intensity and danger of the workers; the vibrating rod can vibrate the concrete without the need for the workers to go down to the working platform, reducing the labor intensity and danger of the workers; the sliding trolley and the hose cooperate to make the concrete paving more even.

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0017] Combined with Figure 1-2, an automatic vibrating device for pier pile foundation concrete, comprising a construction platform 1, a cross plate 2 and a working platform 3 arranged in sequence from top to bottom, the construction platform 1 is provided with a hopper 4 and a symmetrically arranged winch 5, the bottom of the hopper 1 passes through the construction platform 1 and is connected to a telescopic string tube 6, the bottom end of the telescopic string tube 6 passes through the cross plate 2 and is connected to a hose 7, the bottom end of the hose 7 is connected to a sliding trolley 8 slidably connected to the working platform 3, the winch 5 is provided with a steel wire rope 9 fixedly connected to the cross plate 2, the bottom of the cross plate 2 is provided with a hydraulic telescopic device 10 fixedly connected to the working platform 3, and the bottom of the working platform 3 is provided with a plurality of vibrating rods 11.
[0018] The construction platform 1 is provided with symmetrically arranged through holes 12 , and the steel wire rope 9 is arranged in the through holes 12 .
[0019] The telescopic string tube 6 includes a plurality of string tubes 13 that are interconnected.
[0020] The outer side of the bottom of the string tube 13 is provided with an annular protrusion 14 which is arranged around the string tube 13 , and the inner side of the top of the string tube 13 is provided with an annular protrusion 2 15 which matches with the annular protrusion 14 .
[0021] The working platform 3 is provided with a feeding port 16, the sliding trolley 8 is provided with symmetrically arranged ears 17, one end of the feeding port 16 is provided with a groove 18, a symmetrically arranged reduction motor 19 is arranged in the groove 18, and the output end of the reduction motor 19 is provided with a screw 20 threadedly connected to the ear 17.
[0022] The hydraulic telescopic device 10 is a hydraulic cylinder, and the hydraulic cylinders are symmetrically arranged.
[0023] One end of the telescopic string tube 6 close to the transverse plate 2 is fixedly connected to the transverse plate 5 .
[0024] A distance measuring device 21 is provided at the bottom of the working platform 3 .
[0025] During the implementation of the present invention, the staff adds concrete into the hopper 4, and the concrete falls to the bottom of the pier or pile foundation through the telescopic string tube 6, the hose 7 and the sliding trolley 8. The staff turns on the reduction motor 19, and the reduction motor 19 rotates to drive the screw 20 to rotate. The screw 20 drives the ear 17 and the sliding trolley 8 to move laterally in the feeding port 16, so that the concrete is spread more evenly in the pier or pile foundation. The distance measuring device 21 monitors the depth of the concrete in real time. When the depth of the concrete reaches 50 cm, the staff stops the concrete feeding. Feed the material into the hopper 4, and then the staff turns on the hydraulic cylinder, which drives the working platform 3 to move downward, so that the vibrating rod 11 is inserted into the concrete. The vibrating rod 11 vibrates the concrete in the pier or pile foundation for 15 seconds and then is lifted up. This is repeated twice in a row until the concrete surface is slurried and there are no more bubbles (the number of vibrations can be determined by experiments). The hydraulic cylinder is reset, and the winch 5 drives the working platform 3 to be lifted up by 50 cm. The staff adds concrete to the hopper 4 again, and repeats this construction process until the concrete is poured to the designed elevation.
[0026] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
