Description

Technical Field

[0001] This utility model relates to a front support bridge arm structure for a tamping coal loading car, belonging to the technical field of tamping coal loading cars. Background Technology

[0002] Currently, existing tamping coal loading cars have an empty travel distance between the loading point and the carbonization chamber opening. To ensure stable coal entry into the carbonization chamber, a coal support plate mechanism needs to be installed on the steel structure for smoother operation during loading. However, the existing coal support plate mechanism is a fixed structure, which easily leaves residual coal within it during loading, affecting the operation of the coal support plate. Utility Model Content

[0003] To address the technical problems existing in the prior art, this utility model provides a simple, rationally designed front support bridge arm structure for a tamping and loading coal car that can freely rotate and automatically unload coal.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is a front support bridge arm structure for a tamping coal charging car, including a carbonization chamber furnace column and a connecting steel structure. A rotating shaft assembly is installed on the connecting steel structure, a bridge arm assembly is installed on the rotating shaft assembly, and a bridge arm support bracket is installed on the carbonization chamber furnace column. The bridge arm assembly is normally in a vertical state, but during coal charging, it is flipped and horizontal under the action of the coal support plate, with one end supported on the bridge arm support bracket.

[0005] The bridge arm assembly includes a first support beam and a second support beam. The first support beam is installed at the front end of the second support beam. The first support beam and the second support beam are arranged vertically. A counterweight is provided at the bottom of the second support beam. The first support beam is used to support the bridge arm support bracket.

[0006] Preferably, support buffer pads are provided at the bottom of both ends of the first support beam.

[0007] Preferably, the rotating shaft assembly includes a rotating shaft, a bushing, a bearing seat, and a fixing plate. The bushing is installed on the outside of the rotating shaft, and bearing seats are installed at both ends of the bushing. The bearing seats are installed in the U-shaped fixing grooves of the connecting steel structure. A fixing plate is also installed on the outside of the U-shaped fixing grooves of the connecting steel structure. The fixing plate is connected to the bearing seat by bolts.

[0008] Compared with the prior art, the present invention has the following technical effects: The present invention has a simple structure and reasonable design. It adopts an automatic flipping structure, which can make the bridge arm horizontal during coal loading by the coal support plate to assist in coal loading and ensure the stability of coal loading. After coal loading is completed, the bridge arm automatically flips to a horizontal state under the action of the counterweight, which throws off the coal that has fallen on the bridge arm without affecting coal loading and is convenient to use.

[0012] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0013] like Figures 1 to 3 As shown, a front support bridge arm structure for a tamping coal charging car includes a carbonization chamber furnace column 1 and a connecting steel structure 2. A rotating shaft assembly 3 is installed on the connecting steel structure 2, and a bridge arm assembly 4 is installed on the rotating shaft assembly 3. A bridge arm support bracket 5 is installed on the carbonization chamber furnace column 1. The bridge arm assembly 4 is normally in a vertical state, but when charging coal, it is flipped and horizontal under the action of the coal support plate, and one end is supported on the bridge arm support bracket 5.

[0014] The bridge arm assembly 4 includes a first support beam 6 and a second support beam 7. The first support beam 6 is installed at the front end of the second support beam 7. The first support beam 6 and the second support beam 7 are arranged vertically. A counterweight block 8 is provided at the bottom of the second support beam 7. The first support beam 6 is used to support the bridge arm support bracket 5.

[0015] This invention features a freely rotating bridge arm assembly 4 installed between the furnace column 1 and the connecting steel structure 2 in the carbonization chamber. The bridge arm assembly 4 is normally vertical, but during coal loading, it rotates and becomes horizontal under the action of the coal support plate, with one end supported on the bridge arm support bracket 5, thus ensuring stability and reliability during the coal loading process. The bridge arm assembly 4 adopts a T-beam structure, providing stable support on the bridge arm support bracket 5. Support buffer pads 9 are installed at the bottom of both ends of the first support beam 6, which can buffer and reduce noise.

[0016] The rotating shaft assembly 3 includes a rotating shaft 10, a bushing 11, a bearing seat 12, and a fixing plate 13. The bushing 11 is mounted on the outside of the rotating shaft 10, and bearing seats 12 are mounted on both ends of the bushing 11. The bearing seats 12 are respectively installed in the U-shaped fixing grooves connecting the steel structure 2. A fixing plate 13 is also installed on the outside of the U-shaped fixing grooves connecting the steel structure 2, and the fixing plate 13 is bolted to the bearing seats 12. The rotating shaft assembly has a simple structure, is easy to install and fix, and ensures that the bridge arm assembly 4 rotates flexibly and conveniently.
