AI Technical Summary
In the existing technology, when a truck-mounted concrete pump delivers concrete, it cannot be directly inserted into the steel formwork of the silo wall, resulting in concrete scattering and contaminating the slipform platform, affecting the quality of concrete entering the formwork and increasing the amount of cleaning work.
Design a movable hopper, including a hopper body with rectangular, right-angled triangular and square cavity structures, to accommodate truck pump pipes, reduce the impact force of concrete pumping, and ensure that concrete is poured evenly into the steel formwork.
It effectively reduces concrete spillage, ensures the quality of concrete placement, reduces platform pollution, and saves on manual cleaning work.

TECHNICAL FIELD
[0001] The utility model relates to concrete pouring technical field, concretely is a movable hopper for concrete pouring of silo wall. BACKGROUND
[0002] The silo wall is mainly constructed by slip-form process, and the main structural form of the slip-form platform is a "open" frame, which is internally provided with a jack, and the support rod in the embedded concrete is gripped by the jack to lift. The silo wall concrete is poured while the slip-form platform is lifted, and the concrete is generally poured by a truck pump.
[0003] The diameter of the pump pipe of the truck pump is generally 15-20 cm, and when the concrete is poured, the horizontal and vertical steel bars are bound in the silo wall steel formwork. The pump pipe of the truck pump cannot be directly inserted into the silo wall steel formwork for pouring, and can only be placed as close as possible to the upper opening of the silo wall formwork.
[0004] The truck pump has a large force when pumping concrete, which can easily cause the concrete to scatter onto the slip-form platform at the upper opening of the silo wall, causing pollution of the slip-form platform. At the same time, the concrete scattered on the slip-form platform needs to be cleaned into the formwork in time to reduce the redundant load when the slip-form platform is lifted. This makes it difficult to ensure the quality of the concrete into the formwork and requires manual cleaning of the slip-form platform. SUMMARY
[0005] In view of the above prior art, the utility model provides a movable hopper for concrete pouring of silo wall, which is inserted into the hopper when pouring concrete, reducing the impact force of the concrete pumping through the hopper, and pouring the concrete evenly into the steel formwork.
[0006] The utility model provides a movable hopper for concrete pouring of silo wall, which comprises a hopper body, the hopper body comprises a first cavity, the first cavity is set as rectangle, the bottom of first cavity is provided with second cavity, the second cavity is set as right triangle, the inclined surface of second cavity is coincident with the bottom surface of first cavity, the side surface of second cavity is provided with third cavity, the third cavity is set as square, the short right angle surface of second cavity is coincident with the side surface of third cavity, the first cavity, second cavity, third cavity are interconnected.
[0007] Preferably, the top of the hopper body is provided with an ear.
[0008] Preferably, the side of the hopper body is provided with a handrail rod.
[0009] Preferably, the bottom of the hopper body is provided with a plurality of moving wheels.
[0010] Preferably, the moving wheels are connected to the hopper body by a support rod.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model proposes a movable hopper suitable for concrete pouring of silo walls. It has a simple structure, is easy to operate, and can be reused. It can greatly reduce the situation where concrete spills onto the outer platform of the silo wall steel formwork, ensure the quality of concrete entering the formwork, reduce platform pollution, and save labor. Attached Figure Description
[0012] Figure 1 This is a schematic diagram of the structure of a movable hopper suitable for concrete pouring in silo walls, as described in this utility model embodiment.
[0013] Figure 2 This is a schematic diagram illustrating the application of the movable hopper for concrete pouring in silo walls, as described in this utility model embodiment.
[0014] In the diagram, 1-hopper body, 2-lifting lug, 3-handrail, 4-support rod, 5-moving wheel. Detailed Implementation
[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0016] Example: Figure 1 The illustrated movable hopper for pouring concrete into silo walls includes a hopper body 1, which is made of 3mm thick patterned steel plate and includes a first cavity, which is rectangular. A second cavity is located at the bottom of the first cavity and is a right-angled triangle, with its inclined surface coinciding with the bottom surface of the first cavity. A third cavity is located on the side of the second cavity and is square, with its short right-angled surface coinciding with the side surface of the third cavity. The first, second, and third cavities are interconnected. During concrete pouring, the pump nozzle of a truck-mounted concrete pump is inserted into this hopper. This design effectively reduces the impact force during concrete pumping and ensures that the concrete is poured homogeneously into the steel formwork.
[0017] Furthermore, a lifting lug 2 is welded to the top of the hopper body 1. The lifting lug 2 is made of A20 round steel, which facilitates overall lifting. A handrail 3 is welded to the side of the hopper body 1. The handrail 3 is made of A20 threaded steel. Three casters 5 are provided at the bottom of the hopper body 1. The casters 5 are made of plastic pneumatic tires. The casters 5 are connected to the hopper body 1 through support rods 4. The support rods 4 are made of 10# channel steel, which facilitates movement and operation by construction personnel.
[0018] like Figure 2As shown, the movable hopper, in practical application, includes the following steps:
[0019] Step 1: The hopper is assembled, inspected and qualified, and safety technical instructions are given in place;
[0020] Step 2: Use a tower crane to lift the hopper to the slipform platform via lifting lug 2;
[0021] Step 3: Push the hopper to the top of the silo wall to be poured. After the pump truck is in place, insert the pump pipe into the hopper. When discharging, the concrete first enters the hopper and is then uniformly poured into the steel formwork of the silo wall through the hopper opening.
[0022] Step 4: After one section of the silo wall concrete is poured, the hopper is moved to another pouring section to continue construction. Once all pouring is complete, the hopper is lifted to the ground by a tower crane for cleaning, ready for subsequent operations. A warning line is set up during the hoisting of the hopper, and dedicated safety personnel are assigned to supervise the process.
[0023] The movable hopper described in this embodiment is suitable for concrete pouring in silo walls. It has a simple structure, is easy to operate, and can be reused. It can greatly reduce the situation where concrete spills onto the outer platform of the silo wall steel formwork, ensure the quality of concrete entering the formwork, reduce platform pollution, and save labor.
[0024] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent solutions made using the contents of this utility model specification, whether directly or indirectly applied to other related technical fields, are also within the patent protection scope of this utility model.
