Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building construction, in particular to a self-compacting hopper pouring variable control device. Background Art
[0002] Concreting of self-compacting track slabs is a highly specialized construction process that combines advanced concrete technology and precise construction techniques to ensure the stability and durability of the track slabs. The following is a detailed introduction to the concrete pouring of self-compacting track slabs:
[0003] Self-compacting concrete is a special type of concrete that has excellent fluidity and self-filling properties, and can fill all the voids in the formwork without external force vibration, thus forming a uniform and dense concrete structure. This characteristic makes self-compacting concrete perform well in track slab casting, which can greatly improve construction efficiency and quality.
[0004] Before pouring, the track slab needs to be accurately measured and positioned to ensure that its plane position and elevation meet the design requirements. Then, the self-compacting concrete composite formwork is built and fixed to ensure that the formwork fits tightly with the track slab to prevent concrete leakage during pouring.
[0005] During the on-site pouring process, the concrete in the mixing barrel is usually poured directly into the interior through the hopper. The feeding speed of the concrete in the hopper cannot be controlled, and the opening and closing of the concrete in the hopper cannot be controlled. In addition, the poured concrete falls directly into it, which easily causes a large number of bubbles to be generated in the concrete, and the manual operation is too complicated. Utility Model Content
[0006] The purpose of the utility model is to solve the above-mentioned problems of the background technology and to provide a self-compacting hopper pouring variable control device.
[0007] The purpose of the utility model can be achieved through the following technical solutions:
[0008] A self-compacting hopper filling control device comprises a moving device, a support frame and a hopper, wherein the hopper is arranged on the support frame and is suspended on the moving device by a rope. A mounting seat is welded to the bottom of the hopper near a discharge port, a cavity is provided inside the mounting seat, an opening is provided through the side of the mounting seat, the opening is connected to the cavity, a blocking plate is slidably inserted into the opening, and the blocking plate is used to open and / or close the discharge port.
[0009] As a further solution of the utility model: a swing arm is rotatably connected to the mounting seat, and one end of the swing arm is rotatably connected to the blocking plate.
[0010] As a further solution of the utility model: a first connecting member is fixed on the mounting seat, a waist-shaped hole is opened on the first connecting member, and the swing arm is inserted into the waist-shaped hole through a first latch.
[0011] As a further solution of the utility model: the first latch is inserted at two-thirds of the length direction of the swing arm.
[0012] As a further solution of the utility model: a second connecting member is further provided between the swing arm and the blocking plate, the second connecting member is fixed to the swing arm, and the second connecting member is rotatably connected to the blocking plate via a first latch.
[0013] As a further solution of the utility model: a filter screen is installed at the feed inlet of the hopper.
[0014] The beneficial effects of the utility model are as follows: the self-compacting concrete in the mixing tank will be transported to the hopper along with the discharge chute. During the pouring process, the variable control device can control the discharge speed of the self-compacting concrete. And the concrete is poured and does not contact the track plate during the pouring process, reducing the impact on the fine-tuning positioning data of the track plate. It can be directly coordinated with the pouring vehicle for easy carrying, and can realize the rapid positioning of the hopper and the pouring port. The speed of the discharge port can be controlled. The sealing treatment between the discharge port and the roadbed plate pouring port prevents air from entering, which can prevent the air from entering during the pouring process and causing the formation of bubbles inside the self-compacting concrete. It simplifies the traditional manual construction steps, reduces labor, and improves work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
