Description

Technical Field

[0001] The invention relates to the technical field of concrete pouring tooling, in particular to an eight-arm concrete pouring tooling for a bridge tower column. Background Art

[0002] With the development and prosperity of national infrastructure, more and more roads have been built. Through the construction of roads, various regions are connected to each other, ensuring the convenience of material transportation and population flow. Among them, road bridges are a more important part. In the process of bridge manufacturing, concrete is needed for pouring. The rapid manufacturing of bridges is achieved through the characteristics of concrete's easy solidification and plasticity. In the process of construction of the main tower of the cable-stayed bridge, the main tower of the cable-stayed bridge is generally poured using a sky pump. The tower column requires a large volume of concrete pouring, but due to road restrictions, the position of the pump truck is basically fixed. If there are angle problems or obstacles blocking the pouring process, the discharge port of the sky pump will not be It is easy to find a suitable position for discharging materials, which may easily affect the pouring of concrete. For this reason, the position of the pump station needs to be adjusted again. However, due to the restrictions of road conditions and the time spent on moving, the adjustment time is likely to be longer. At this time, the concrete will solidify due to the long time interval, resulting in discontinuous pouring. In addition, the discharge end of the sky pump needs to be equipped with multiple people to pull, drag, and push the pump pipe in different forms to achieve the conversion of the pouring position. During this period, cyclic pouring is required between different positions, and the interval time is long. At the same time, discontinuous pouring at a single position will not be conducive to the continuous operation of concrete when discharging and pouring is carried out again. It will limit the overall work efficiency and affect the quality of construction pouring. Summary of the Invention

The pump truck can inject concrete from one direction and discharge from eight directions without changing its position, thereby meeting the pouring needs in eight directions, ensuring the continuity of concrete pouring, improving work efficiency, and ensuring pouring quality.

[0023] Compared with the prior art, the present invention has the following beneficial effects: the eight-arm concrete pouring tool for the bridge tower column: 1. When pouring, you only need to assemble the tooling and place it at the pouring site. Then you can use the overhead pump to inject concrete into the silo, so that the concrete in the silo can be discharged to the outside through the pouring ports in eight directions. Without changing the pump station position, concrete can be injected into the silo from one direction and discharged in eight directions at the same time to meet the pouring needs in eight directions. This saves the pump truck from having to spend a lot of time changing its position, reduces the discontinuity of pouring caused by a long time changing position, and reduces the problem of affecting the pouring quality due to displacement. 2. The inclined top guide cone can make the concrete discharged into the silo be discharged more smoothly from the pouring port. At the same time, the eccentric block can be driven to rotate by the rotation of the driving motor, so that the eccentric block can vibrate as it rotates. The eccentric block can rotate and vibrate to shake off the concrete adhering to the inner wall of the silo, so that the concrete injected into the silo will not remain excessively, and the probability of concrete accumulation and jamming inside the silo can be reduced. The concrete in the silo can be discharged as much as possible to reduce the residue. At the same time, the probability of concrete jamming inside the silo can be reduced when discharging the concrete. 3. During assembly, you only need to insert the extension slot into the oblique clip. The oblique clip is designed to be larger at the top and smaller at the bottom, so that the extension slot can be inserted into the inside of the pouring mouth. It can be extended through the extension tube to cover most pouring positions. The detachable design of the extension slot and extension tube allows the extension tube to be stored inside the bracket and the extension slot to be stored between the base plate, bracket and fence, so that the tooling can be reduced in size when not in use for easy transportation and movement. 4. When the silo discharges concrete to the outside, the elastic pin can be pulled to disengage the elastic pin from the plug hole. Then the adjustment baffle can be moved to adjust the opening size of the pouring port, so that the amount of concrete discharged from the pouring port in eight directions can be adjusted, and the speed of discharging concrete can be adjusted. Then the elastic pin can be loosened and plugged into the plug hole, so that the adjustment baffle will not be displaced due to the impact generated by the concrete discharge after being fixed, so that the speed and discharge amount of concrete in the eight directions of the silo can be adjusted.

[0034] The support frame 9 can provide support for the extension slots 6 on both sides of the platform 3, so that the extension slots 6 without the support of the fence 10 can be supported and can be folded and stored when stored.

[0035] The outer surface of the end of the silo 4 away from the platform 3 is evenly provided with a bayonet 12, and the outer surface of the bayonet 12 fits with the discharge port of the sky pump. The outer surface of the end of the silo 4 close to the bayonet 12 is provided with a lifting hole 11, and the lifting hole 11 is symmetrically designed.

At the same time, the guardrail 21 can protect the workers who climb onto the platform 3 for cleaning, reducing the chance of workers falling from the platform 3. At the same time, the roller 20 can be used to move through the guide rail after the pouring is completed, so that workers do not need to pull, drag, or push the pump pipe, thereby reducing the labor intensity of the workers.
