Abstract
Description
Technical Field
[0001] This utility model relates to the field of building construction technology, specifically to a concrete pouring control device. Background Technology
[0002] Concrete pouring is a crucial step in building construction. The quality of concrete pouring directly affects the forming quality and aesthetic appeal of the concrete structure. Aesthetic appeal directly influences people's evaluation of the building's beauty, especially for structures with special requirements for concrete appearance quality, such as fair-faced concrete.
[0003] In existing technologies, due to the lack of concrete pouring control measures during the concrete pouring process, concrete of different strengths is often spilled onto the formwork during the movement of the pump pipe. This results in significant color differences in the concrete surface, which greatly affects the appearance of the concrete and thus the overall aesthetic quality of the concrete structure. Utility Model Content
[0004] The purpose of this utility model is to provide a concrete pouring control device to solve the following technical problems:
[0005] How to control the discharge of material from a moving pump pipe during concrete pouring.
[0006] The objective of this utility model can be achieved through the following technical solutions:
[0007] A concrete pouring control device includes a left half-circle clamp and a right half-circle clamp. One end of the left half-circle clamp is movably connected to one end of the right half-circle clamp, and they enclose to form a circular tube. The other end of the left half-circle clamp is detachably connected to the other end of the right half-circle clamp. A through wheel groove is provided on the left half-circle clamp or the right half-circle clamp, and a knife gate is rotatably installed thereon. The knife gate is movably disposed in the through wheel groove.

A fixing pin is provided in the second mounting groove, and a movable bolt is provided on the fixing pin. A screw hole matching the movable bolt is provided between the first mounting grooves.
[0011] In a further embodiment of this utility model: a knife handle is installed on the knife gate.
[0012] In a further embodiment of this invention: the knife handle is connected to the end of the knife gate furthest from the rotating end.
[0013] In a further embodiment of this invention, the handle is provided with anti-slip texture.
[0014] In a further embodiment of this utility model: the left half-circle clamp and the right half-circle clamp are used to be installed on the concrete pouring pump pipe.
[0015] In a further embodiment of this utility model: the left half-circle clamp and the right half-circle clamp are used to be installed at the outlet end of the concrete pouring pump pipe.
[0016] In a further embodiment of this utility model, the method of using the concrete pouring control device is as follows:
[0017] Step 1: Install the left half-circle clamp and the right half-circle clamp together at the end of the concrete pump pipe, and then fix the ends of the left half-circle clamp and the right half-circle clamp together with the movable bolt.
[0018] Step 2: Drive the knife gate to rotate by the knife handle, so that the knife gate rotates through the wheel groove and enters between the left half-circle clamp and the right half-circle clamp, thereby closing or opening the outlet end of the pump pipe and realizing the control of concrete discharge.
[0019] The beneficial effects of this utility model are:
[0020] In use, the concrete pouring control device of this utility model involves installing the left and right half-circle clamps together at the end of the concrete pump pipe, and then fixing the ends of the left and right half-circle clamps together with movable bolts. This achieves a fixed installation of the left and right half-circle clamps. Because sealing rings are provided inside the left and right half-circle clamps, the sealing performance is improved, and the sealing performance increases accordingly with the fluid pressure inside the pipe. The knife handle drives the knife gate to rotate, allowing the knife gate to rotate through the wheel groove and enter between the left and right half-circle clamps, thereby closing or opening the outlet end of the pump pipe, controlling the concrete discharge and preventing random spraying of concrete during pump pipe movement. After concrete pouring is completed, the device can be disassembled for subsequent reuse. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figure 1 This embodiment discloses a concrete pouring control device, including a left half-circle clamp 3 and a right half-circle clamp 4. Both the left half-circle clamp 3 and the right half-circle clamp 4 are semi-arc-shaped, and one end of the left half-circle clamp 3 and one end of the right half-circle clamp 4 are respectively provided with a matching hinge part. A through hole is provided on the matching hinge part, and a rotating pin 5 is inserted through the through hole. Both the left half-circle clamp 3 and the right half-circle clamp 4 can rotate around the rotating pin 5. When the left half-circle clamp 3 and the right half-circle clamp 4 rotate and surround each other, they can form a circular tube shape, so as to facilitate installation on the concrete pouring pump pipe.
[0026] Both the left half-circle clamp 3 and the right half-circle clamp 4 are provided with sealing rings 10 on their inner sides. The shape of the sealing rings 10 matches the shape of the through wheel groove 11. Therefore, when the left half-circle clamp 3 and the right half-circle clamp 4 are installed on the pump pipe, the sealing performance can be improved under the action of the sealing rings 10.
[0027] Mounting groove 2 7 and mounting groove 1 6 are respectively provided at the ends of the left half-circle clamp 3 and the right half-circle clamp 4 away from the rotating pin 5. A fixing pin 9 is provided in mounting groove 2 7, and a movable bolt 8 is provided on the fixing pin 9. A screw hole is provided between mounting groove 1 6. By inserting the movable bolt 8 into the screw hole, the ends of the left half-circle clamp 3 and the right half-circle clamp 4 can be connected. The left half-circle clamp 3 and the right half-circle clamp 4 are arranged around the outlet end of the pump pipe and locked by the fixing pin 9, so that the left half-circle clamp 3 and the right half-circle clamp 4 can be fixed on the pump pipe.
[0028] A through-groove 11 and a rotatable knife gate 2 are provided in the middle of the back of the left half-circle clamp 3 or the right half-circle clamp 4. For example, in this utility model, the through-groove 11 and the knife gate 2 are provided on the left half-circle clamp 3. The end of the knife gate 2 is connected to a knife handle 1. The knife handle 1 drives the knife gate 2 to rotate, so that the knife gate 2 can rotate through the groove and enter between the left half-circle clamp 3 and the right half-circle clamp 4, thereby closing or opening the outlet of the pump pipe and realizing the control of concrete discharge.
[0029] The working principle of this utility model:
[0030] When using this device, the left half-circle clamp 3 and the right half-circle clamp 4 are installed around the end of the concrete pump pipe. Then, the ends of the left half-circle clamp 3 and the right half-circle clamp 4 are fixedly connected by the movable bolt 8, thus achieving the fixed installation of the left half-circle clamp 3 and the right half-circle clamp 4. Since the left half-circle clamp 3 and the right half-circle clamp 4 are provided with sealing rings 10 on the inner side, the sealing performance of the installation can be improved, and the sealing performance is correspondingly enhanced with the fluid pressure in the pipe. By driving the knife handle 1 to rotate the knife gate 2, the knife gate 2 can rotate through the wheel groove and enter between the left half-circle clamp 3 and the right half-circle clamp 4, thereby closing or opening the outlet end of the pump pipe and realizing the control of concrete discharge. After the concrete is poured, the device can be disassembled for subsequent recycling.
