[0031] In order to make the purpose, technical solutions and beneficial effects of the present application clearer, the preferred embodiments of the present application will be described in detail below with reference to the accompanying drawings to facilitate understanding by technical personnel.
[0032] Example 1:
[0033] See also Figures 1 to 3 A railway bridge deck cable trough side wall concrete pouring hopper, comprising a pair of cable trough side wall templates 1, the railway bridge deck cable trough side wall concrete pouring hopper also includes:
[0034] The hopper body 2 has a first pouring port 3 and a second pouring port 4 on both sides of its lower end;
[0035] The first slide rail 5 is fixed on the inner side wall of one of the cable trough side wall templates 1;
[0036] The second slide rail 6 is fixed to the inner wall of another cable trough side wall template 1;
[0037] Among them, the first slide rail 5 is slidably connected to the first slider 7, the bottom of the side wall of the first pouring port 3 is fixed on the first slider 7, the second slide rail 6 is slidably connected to the second slider 8, and the bottom of the side wall of the second pouring port 4 is fixed on the second slide rail 6.
[0038] Specifically, the cable trough side wall template 1 is surrounded by four steel plates, and adjacent steel plates are fixed by screws; the upper part of the hopper body 2 is open to facilitate concrete injection, and the middle part of the hopper body 2 is hollowed out, and the cross-section of the hollowed-out area is trapezoidal in shape to reduce the overall weight of the device; the length of the first slide rail 5 and the second slide rail 6 matches the length of the cable trough side wall template 1.
[0039] During use, the first slider 7 and the second slider 8 are slidably installed on the first slide rail 5 and the second slide rail 6 respectively, and the first slide rail 5 and the second slide rail 6 are fixedly installed on the inner wall of the cable trough side wall template 1. The lower end of the hopper body 2 is fixed to the first slider 7 and the second slider 8 on both sides respectively, and then concrete is poured into the hopper body 2. Through the guiding effect of the first pouring port 3 and the second pouring port 4, the concrete is poured into the cable trough side wall template 1.
[0040] This application adopts a hopper to ensure that the concrete is evenly distributed when it flows out, thereby improving the continuity and uniformity of pouring and ensuring the quality of concrete molding. By installing the first slide rail 5 and the second slide rail 6 on the cable trough side wall template 1, the hopper body 2 is connected to the cable trough side wall template 1, solving the problem of difficult distribution due to long pouring length.
[0041] At the same time, by providing the first pouring port 3 and the second pouring port 4, synchronous pouring of the side walls on both sides is achieved, thereby improving the pouring efficiency and reducing manpower and material waste.
[0042] In addition, based on the above scheme, the first slide rail 5 and the second slide rail 6 can be rotated downward 90° and installed on the inner wall of the cable trough side wall template 1, and the first slider 7 and the second slider 8 can be connected to the side walls of the first pouring port 3 and the second pouring port 4. In this way, the above purpose can be achieved, and the bottom of the first slide rail 5 and the second slide rail 6 can be flush with the bottom of the first pouring port 3 and the second pouring port 4, so that the molding quality of the upper end surface of the concrete is improved.
[0043] Example 2:
[0044] See also Figures 1 to 3 Based on the first embodiment, optionally, the cross-sections of the first slider 7 and the second slider 8 are T-shaped.
[0045] Specifically, the T-shaped slider, due to its unique "T" structure, provides excellent support in both vertical and horizontal directions, making the slider more stable during movement and less prone to deviation or shaking. The T-shape provides a clear guide for the slider, helping to achieve precise linear motion or reciprocating motion.
[0046] In addition, wear-resistant blocks or coatings can be provided on the contact surfaces of the first slider 7 and the second slider 8 to improve the wear resistance of the sliders and extend their service life. When the wear-resistant blocks are worn, they can be easily replaced, reducing maintenance costs.
[0047] Optionally, T-slots matching the first sliding block 7 and the second sliding block 8 are formed on the first sliding rail 5 and the second sliding rail 6 .
[0048] Specifically, the T-slots on the first slide rail 5 and the second slide rail 6 provide a clear guide path for the first slider 7 and the second slider 8, which helps to achieve precise position control and motion guidance, thereby improving the flatness of the concrete after molding.
[0049] Optionally, the hopper body 2 has an arc-shaped guide surface 9 therein.
[0050] Specifically, the inner wall of the hopper body 2 is configured as an arc-shaped guide surface 9 with a certain curvature to facilitate the sliding of concrete, thereby reducing the adhesion and accumulation of concrete on the inner wall of the hopper body 2, thereby reducing corrosion and increasing service life.
[0051] Optionally, the first slide rail 5, the second slide rail 6 and the inner side wall of the cable trough side wall template 1 are detachably fixed by screws.
[0052] Specifically, the detachable fixing by screws facilitates the disassembly and installation of the first slide rail 5 and the second slide rail 6, thereby speeding up the work progress.
[0053] Optionally, both the inner and outer surfaces of the hopper body 2 are coated with an anti-corrosion paint layer.
[0054] Specifically, the anti-corrosion paint layer forms a strong protective film to prevent oxygen, moisture, and other chemicals from directly contacting the inner and outer surfaces of the hopper body 2, thereby slowing down or preventing the corrosion process. In this way, the service life is improved and the performance of the hopper body 2 is guaranteed.
[0055] It should be noted that the structures and / or installation methods not detailed in this application are known to those skilled in the art in combination with common knowledge and / or existing technologies, and are not the focus of disclosure in this application and will not be further elaborated here.
