Description

[Technical Field]

[0001] The present invention relates to the field of concrete pouring technology, and more particularly to a concrete pouring device for bridge cage construction. [Background technology]

[0002] Concrete pouring is an important step in the construction of bridge suspension structures, and the quality of the pouring directly affects the overall strength, stability, and durability of the bridge structure. Currently, concrete pouring in bridge suspension structure construction is always carried out using pump trucks, which are widely used in various bridge construction projects due to their flexible mobility and efficient pumping capacity.

[0003] However, during actual construction, when the concrete mixing transport vehicle discharges concrete directly from its discharge port into the pump truck's supply hopper, the concrete has a large weight and a certain fluidity, so it can apply a large impact force to the pump truck's supply hopper during the free fall process. Such a strong impact can damage the structure of the pump truck's supply hopper, causing local deformation of the supply hopper and shortening its service life. Therefore, we have improved this and proposed a concrete pouring device for bridge construction using a hanging cage. Summary of the Invention [Means for solving the problem]

By providing the protective structure on the hopper body, the protective structure reduces the impact force when concrete falls from the discharge port of the concrete mixing transport vehicle onto the hopper body, thereby reducing the impact on the hopper body and extending the service life of the hopper body.

[0016] In order to allow those skilled in the art to better understand the present invention, the following will clearly and completely describe the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention, but it is clear that the described embodiments are only some embodiments of the present invention and do not represent all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments in the present invention without any creative work shall fall within the scope of protection of the present invention.

[0017] Furthermore, if there is no conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0018] Note that like symbols and letters represent like items in subsequent figures, so once an item is defined in one figure, it need not be further defined and interpreted in subsequent figures.

[0019] 1 to 5, the concrete pouring device for bridge construction includes a pump vehicle body 1, which includes a hopper body 101, which is provided with a protective structure 2, which includes a support provided on the hopper body 101, to which a protective frame 204 is connected, and several stoppers 205 are fixedly attached within the protective frame 204. By providing the protective structure 2 on the hopper body 101, the protective structure 2 reduces the impact force when concrete falls from the discharge port of the concrete mixing transport vehicle into the hopper body 101, thereby reducing the impact on the hopper body 101 and extending the service life of the hopper body 101. Because the concrete falls into the protective frame 204 before falling into the hopper body 101, the stoppers 205 reduce the impact of the concrete on the hopper body 101.

[0020] The pump vehicle body 1 is an existing facility, and its specific structure, principle and method of use are all conventional technologies, and will not be further described in this application.

[0021] Furthermore, the bottom end of the protective frame 204 is inserted into the inner wall of the hopper body 101. A gap is left between the protective frame 204 and the inner wall of the hopper body 101, and the provision of this gap reduces the impact force received by the protective frame 204 from being transmitted to the hopper body 101.

[0022] Furthermore, the support body includes a connecting frame 209 fixedly attached to the outer periphery of the hopper body 101, and a plurality of support pipes 201 are fixedly connected to the outer surface of the connecting frame 209. The connecting frame 209 can support the support pipes 201.

[0023] Furthermore, the support further includes two connecting plates 203 fixedly attached to both sides of the protective frame 204, and the support rods 202 are fixedly attached to the bottom of the connecting plates 203, and the bottom ends of the support rods 202 are inserted into the support tubes 201. The protective frame 204 and the support tubes 201 can be connected by fitting the support rods 202 into the connecting plates 203. With the support rods 202 fitted into the support tubes 201, the protective frame 204 can be removed by pulling it upward, making cleaning easier. After cleaning is complete, the support rods 202 can be fitted into the support tubes 201 by simply fitting them back together.

[0024] Furthermore, an elevating member is connected to the support tube 201 .

[0025] Furthermore, the lifting member includes a hydraulic cylinder installed inside the support tube 201, and the bottom end of the hydraulic cylinder is connected to a shim plate 206 located at the bottom of the support tube 201. During use, the hydraulic cylinder moves the shim plate 206 downward to contact the ground, thereby stably supporting the support tube 201 and the hopper body 101.

[0026] Furthermore, a protector is provided on the upper part of the protective frame 204. This protector is for protecting the protective frame 204 when not in use.

[0027] Furthermore, the protective gear includes a protective plate 207 disposed on top of the protective frame 204. The protective plate 207 can protect the protective frame 204 when not in use.

[0028] Furthermore, the side of the protective plate comes into contact with the side of the connecting plate 203. When the protective plate 207 is at the top of the protective frame 204, it can receive the stopper of the connecting plate 203, thereby increasing the stability of the protective plate 207.

[0029] Furthermore, latches 208 are provided between the protective plate 207 and the two connecting plates 203. The position of the protective plate 207 can be fixed by the latches 208. The latches 208 are existing components, and their specific structure, unlocking and locking methods are all prior art, and will not be further described in this application.

[0030] The use process of the concrete pouring equipment for bridge construction provided by this invention is as follows: After the latch 208 is unlocked, the protective plate 207 is removed, the hydraulic cylinder-driven shim 206 in the support pipe 201 descends and touches the ground, and the concrete falls first from the outlet of the concrete mixing transport vehicle into the protective frame 204. As the concrete falls, it collides with the stopper 205, consuming its kinetic energy and further reducing the impact of the concrete on the hopper body 101 through the stopper 205. The concrete then falls into the hopper body 101 and is pumped in by the pump vehicle body 1.

For example, they may be fixedly connected, detachably connected, or integral. They may be mechanically connected, electrically connected, capable of communicating with each other, directly connected, or indirectly connected via an intermediate medium, and, unless otherwise limited, may refer to a connection within two elements or an interactive relationship between two elements.
