Technical Field

The utility model relates to a commodity circulation field, concretely relates to extending flatbed.

Background

Flat cars are a common mode of transportation in distribution environments for moving bulk cargo. A very simple design provides a basic platform with four wheels for pushing or pulling the platform and the load on the platform.

The frame is typically prefabricated steel. The major flat surfaces may be constructed of wood, plastic, steel or mesh. The flat wheel can vary considerably, being solid rubber, air-filled or cast iron. The wheels are typically part of a flat car, limiting safe operation. Specialized carts include piano carts that have long been provided with small multi-swivel casters and stronger frames than usual. Modern factory systems often track individual carts with a digital pipeline so that automated lift order automation systems may have remote operation or automated cart transport during transport and access. The current hand-pushed flat car has the defect that the current hand-pushed flat car cannot bear large-volume goods, particularly goods with larger length.

The limiting support 13 is provided with a hole, and the limiting cross rod 11 penetrates through the hole of the limiting support 13 to be connected with the limiting spring 12.

As shown in fig. 2, two ends of the bottom flat plate 2 are connected with the front extension flat plate 3 and the rear extension flat plate 4 through hinges 5, the lower part of the bottom flat plate is welded with a reinforcing support plate 6, and the rear end of the rear positioning plate 43 is in pin joint with the bottom flat plate 2. The rear ends of the front extension stay bar 71 and the rear extension stay bar 72 are connected with the reinforcing support plate 6 through a positioning bolt 8, and the lower parts of the front ends of the front extension stay bar 71 and the rear extension stay bar 72 are connected with the tire device. The reinforcing support plate 6 includes two longitudinal support plates 61 and four lateral support plates 62. The front extension strut 71 comprises two first longitudinal struts 711 and one first transverse connecting bar 712. The rear extension stay 72 includes two second longitudinal stays 721 and one second transverse link 722.

As shown in fig. 3, is a left side view of the structure of the present invention. The outer side of the pull rod 1 of the limiting cross rod 11 is pressed down to lose the limiting cross rod 11, the limiting spring 12 is stretched, the pull rod 1 rotates around the spring fixing pin 14, and horizontal folding is achieved. This way of folding the tie rods is present on most flatbeds today.

As shown in fig. 4, the lower end of the locking block 92 passes through the shaft, the upper end of the locking block 92 is suspended at the upper end of the tire 93, the lower end of the movable bracket 94 is sleeved outside the locking cam 91, and the cam of the locking cam 91 is clamped in the groove at the outer side of the locking block 92. The locking cam 91 rotates to a horizontal position to lock the tire 93, and rotates to a vertical position to unlock the tire 93.

As shown in fig. 5, when the back extension flat plate 4 is folded, one of the locking grooves of the back positioning block 43 may be engaged with the side protruding rod of the back extension flat plate 4, and when the back extension flat plate 4 is vertical, the other locking groove of the back positioning block 43 may be vertically positioned on the back extension flat plate 4.
