Description

Technical Field

[0001] This utility model belongs to the field of bridge construction technology, specifically relating to a concrete pouring and placing device. Background Technology

[0002] Bridge pouring is a core part of bridge construction, its function being to form the main structure of the bridge through concrete pouring, ensuring the strength, stability, and durability of the structure. Concrete pouring and distribution devices, mainly used for the final delivery and distribution of concrete, can accurately and efficiently deliver concrete to construction sites such as the bridge deck and piers, thereby optimizing the bridge pouring process and improving construction quality and efficiency.

[0003] Chinese patent document CN222758737U discloses a concrete pouring and placing device for bridge construction. After concrete is introduced into an inclined chute with multiple discharge ports that can move longitudinally, a moving trolley limited by a guide frame is connected to the end of a concrete placing hose. This allows the multiple placing hoses to move laterally under the inclined chute, so that the concrete flowing out of the discharge ports can be guided to different positions on the bridge deck, thereby effectively reducing pumping costs and the labor intensity of workers.

[0004] However, in the existing technology, the concrete that flows into each pipeline by its own weight in the concrete placing device is difficult to accurately pour to the required position of the bridge outside the horizontal projection area of ​​the concrete placing device. Therefore, a concrete pouring and placing device is proposed. Utility Model Content

[0030] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0031] like Figures 1-4 As shown, a concrete pouring and placing device includes a loading assembly 1 that can install multiple key components of the device at different heights, a feeding assembly 2 that can deliver concrete to each placing channel at the required speed, and a placing assembly 3 that can accurately pour the delivered concrete to the required position on the bridge below the feeding assembly 2.

[0032] In this embodiment: the loading component 1 includes an anti-tilt seat 101, and uprights 102 are fixedly installed on the front and rear sides of both sides of the anti-tilt seat 101.

[0033] The anti-tipping seat 101 with a large bottom area provides an installation position for the upright 102 and the hydraulic cylinder 305, and improves the anti-tipping ability of the device. The upright 102 is used to install the bracket 201 and the feed hopper 202, and allows some parts of the feeding assembly 2 and the cloth distribution assembly 3 to be set in the area between the anti-tipping seat 101 and the feed hopper 202.

[0034] In this embodiment: the feeding assembly 2 includes a bracket 201 fixedly connected to the upper end of the upright 102, a feeding hopper 202 fixedly connected to the upright 102 is provided below the bracket 201, a bearing seat 203 is fixedly installed on the upper and lower parts of the bracket 201, a rotating shaft 204 is movably connected between the two bearing seats 203, a drive unit 205 is fixedly connected to the upper end of the rotating shaft 204, a spiral blade 206 is fixedly connected to the outer side of the rotating shaft 204, and a guide cylinder 207 is fixedly connected below the feeding hopper 202;

[0035] The bearing seat 203 is rotatably connected to the rotating shaft 204, and the feed hopper 202, bearing seat 203, rotating shaft 204, and guide cylinder 207 are coaxial;

[0036] The bearing seat 203 and the drive unit 205 are installed above the feed hopper 202 via the bracket 201. The concrete to be poured is fed into the feed hopper 202. The rotating shaft 204 installed below the bracket 201 via the bearing seat 203 can transmit the rotation of the output end of the drive unit 205 to the spiral blade 206. The drive unit 205 can be composed of a motor, reducer, etc. The rotating spiral blade 206 can control the speed at which the concrete falls into the guide cylinder 207 and the diverter 301.

[0037] In this embodiment: the material distribution assembly 3 includes a diversion frame 301 fixedly connected below the material guide cylinder 207. The diversion frame 301 has multiple outlets, which can receive and transport the concrete flowing out of the outlets of the diversion frame 301. An adjusting component can be used to adjust the position of the end of the material guide according to the pouring needs.

[0038] The material guiding component includes a reversing frame 302 movably connected to the discharge port of the diverting frame 301. An extension frame 303 is movably connected below the reversing frame 302. An electric push rod 304 fixedly connected to the extension frame 303 is fixedly installed on the lower side of the reversing frame 302. The adjusting component includes a hydraulic cylinder 305 fixedly installed on the anti-tilt seat 101. A lifting block 306 is fixedly connected to the telescopic end of the hydraulic cylinder 305. A support rod 307 is provided between each reversing frame 302 and the lifting block 306.

[0039] Multiple discharge ports are arranged at equal angles around the axis of the diverter 301. The diverter 301 is rotatably connected to the reversing frame 302. The reversing frame 302 is slidably connected to the extension frame 303. The reversing frame 302 and the lifting block 306 are rotatably connected to the support rod 307. The guide cylinder 207, the diverter 301, and the lifting block 306 are coaxial. The rotating shaft 204 passes through the guide cylinder 207 and partially passes through the diverter 301.

[0040] The injected concrete is guided to guide components at different positions by a diversion frame 301 with multiple discharge ports. The concrete flowing out of the corresponding discharge port of the diversion frame 301 is received and transported by a reversing frame 302 and an extension frame 303 that can slide relative to the reversing frame 302 due to an electric push rod 304. The height of the lifting block 306 is adjusted by a hydraulic cylinder 305, and the height change of the lifting block 306 is transmitted to the reversing frame 302 by a support rod 307. This allows the guide components composed of the reversing frame 302 and other components to rotate relative to the diversion frame 301 due to the operation of the hydraulic cylinder 305.

[0041] Working principle: When this device is installed for concrete pouring and placing in bridge construction, after moving the device to the required position on the bridge, the positions of the ends of each extension frame 303 away from the diversion frame 301 are adjusted by the operation of the electric push rod 304 and the hydraulic cylinder 305. After the ends of the extension frames 303 are aligned with the position to be poured on the bridge, the concrete can be continuously injected into the hopper 202 when the drive unit 205 is running. The concrete can enter the diversion frame 301 at the required speed along the guide cylinder 207 due to the rotation of the spiral blade 206. Then, it flows to the position to be poured on the bridge through the various discharge ports of the diversion frame 301 in different positions, as well as the reversing frame 302 and extension frame 303 below each discharge port.

[0042] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
