Description

Technical Field

[0001] The utility model relates to the technical field of tarpaulin carriage structures, and particularly relates to a column structure of a tarpaulin carriage. Background Art

[0002] To maintain the cleanliness and hygiene of the urban environment, the state has tightened the supervision and management of the transportation of construction waste and engineering soil, requiring that the transportation vehicles for construction waste and engineering soil be sealed during transportation. Therefore, such vehicles need to be equipped with tarpaulins. Since the tarpaulin needs to completely cover the carriage of a large truck, the method of manual laying is not only inefficient but also dangerous. Subsequently, an electric tarpaulin system was born on the market to complete the automatic covering and retracting of the tarpaulin. The electric tarpaulin system includes a motor assembly, a driving sprocket, a roller assembly, a tarpaulin rod driving bracket and a tarpaulin. By using the driving sprocket laid along the side of the carriage, under the drive of the motor assembly and the roller assembly, the tarpaulin fixed by the tarpaulin rod driving bracket and the driving sprocket is driven to slide on the top of the carriage along the front and back directions of the vehicle, completing the covering and retracting operations.

[0003] To install the tarpaulin system, the carriage structure needs to be reformed, and fixed positions for the equipment of the tarpaulin system and corresponding inspection holes need to be designed. Therefore, it is necessary to improve the existing carriage structure. Based on this background, this solution focuses on the column structure of the carriage and tries to complete the structural transformation of the traditional carriage with the least changes.

[0031] As Figures 1-4 shown, a column structure of a tarpaulin carriage 2 includes a column base 1. The column base 1 is a rectangular column and plays a main supporting role. A rectangular frame 3 is welded on the top of the column base 1. The outer end face and the inner end face of the rectangular frame 3 are open. Defining the outside of the carriage 2 as the outside and the inside as the inside, that is Figure 2 、 Figure 4 the left side in

[0032] is the outside and the right side is the inside. The rectangular frame 3 forms a hollow internal space for installing and placing a tarpaulin driving assembly 5. The inside of the rectangular frame 3 is blocked by the side plate of the carriage 2, and the outside needs to be blocked by a cover plate 4. The cover plate 4 is covered at the opening of the outer end face of the rectangular frame 3. Among them, the edge of the outer end face of the rectangular frame 3 extends vertically towards the middle to form a folded edge 6, and a fastener is arranged on the folded edge 6 to lock the cover plate 4. Figure 1 、 Figure 2 As shown in

[0033] 、 Figure 3 : In the first embodiment of this solution, the fastener is a bolt 7. The cover plate 4 overlaps on the outer end face of the folded edge 6. The bolt 7 passes through the overlapping part of the cover plate 4 and the folded edge 6, and the bolt 7 is threadedly connected to the folded edge 6. Specifically, a first through hole is opened on the cover plate 4, a second through hole is opened on the folded edge 6, and a first nut is welded on the inner end face of the folded edge 6. The bolt 7 passes through the first through hole, the second through hole and is threadedly connected to the first nut. The internal thread of the first nut itself is fixed to the bolt 7, replacing tapping on the folded edge 6, reducing the process, improving the efficiency and reducing the cost. The first through hole is preferably arranged at the four corners of the cover plate 4. Figure 4 As shown in

[0034] : In the second embodiment of this solution, the cover plate 4 has the same opening shape as the outer end face of the folded edge 6. The fastener includes a bolt 7 and a fixing plate 8. The fixing plate 8 is attached to the inner end face of the folded edge 6. The cover plate 4 is embedded in the opening of the folded edge 6. The bolt 7 passes through the overlapping part of the cover plate 4 and the fixing plate 8 and is threadedly connected to the fixing plate 8. The structure of the cover plate 4 fits the opening of the outer end face of the folded edge 6. When the cover plate 4 is attached to the fixing plate 8, the outer end face of the cover plate 4 is flush with the folded edge 6. In actual production, a plate can be taken and bent to form a rectangular frame 3 with a single-sided opening, and then cut on the rectangular frame machine to form an outer opening. Specifically, by the way of nested cutting, the remaining material of the inspection hole cut off can be used for the inspection hole cover plate 4, and the cover plate 4 has the same shape as the inspection hole of the outer opening. It can effectively reduce the production cost and improve the appearance.
