Description

Portal frame anti-roll dog

Technical Field

The utility model belongs to the technical field of packing box portal frame annex, concretely relates to portal frame anti-roll dog.

Background

The portal frame used for separating the front part from the rear part is arranged between the container and the cab, the portal frame is generally slightly higher than the roof, and when the height of the goods is higher than that of the portal frame, the height of the portal frame is not enough to prevent the goods from rolling to the roof and the brake lamp, so that the goods are easy to fall off or the parts of the vehicle body are easy to damage. In order to avoid the above problems, it is common to design a rolling prevention structure of the container gantry, as shown in fig. 6, to realize a rolling prevention function by using an aluminum alloy pipe rolling prevention frame 4. However, the cost of the aluminum alloy pipe roll cage is high, thereby increasing the manufacturing cost.

In order to save cost, most of the existing portal frames adopt metal plate portal frames, and although the cost of the metal plate portal frames is low, the metal plate portal frames cannot realize an anti-rolling function due to the fact that the metal plate portal frames do not have anti-rolling structures.

Disclosure of Invention

The utility model aims at providing a portal frame anti-roll dog, it is installed on the panel beating portal frame, can realize preventing keeping off the function.

A portal frame anti-roll dog, including the dog body, this dog body is whole to be the shape of falling U, and it is including first facade, top surface and the second facade that connects gradually, the fixed breach of rope has been seted up to the lower limb of first facade and second facade, the left end of first facade and second facade extends round pin axle installation department left to round pin axle hole has been seted up on each round pin axle installation department.

The portal frame anti-rolling stop block is fixedly compressed by a fixing pin through a pin shaft hole and is fixed on an upper cross beam of the portal frame, and the fixing pin is used for compressing and fixing to prevent the portal frame anti-rolling stop block from shaking and generate abnormal sound.

The portal frame anti-rolling stop block is of a self-symmetrical structure, is good in universality, reduces the number of dies, reduces the development cost, and meanwhile avoids the risk of manual missing installation.

The utility model has the advantages of it is following: the portal frame anti-rolling stop block is arranged on the metal plate portal frame, can realize the portal frame anti-rolling function, is designed into a general structure, reduces the number of dies, reduces the development cost, avoids the risk of wrong neglected loading of workers, and more effectively ensures the production beat.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1 to 5, the portal frame anti-rolling stopper has an inverted U-shaped body, and includes a first vertical surface 1a, a top surface 1b and a second vertical surface 1c connected in sequence, wherein a rope fixing notch 1d is formed in the lower edge of the first vertical surface 1a and the second vertical surface 1c, and the rope fixing notch 1d is used for fixing a rope. The left ends of the first vertical surface 1a and the second vertical surface 1c extend leftwards to form pin shaft mounting parts 1e, and each pin shaft mounting part 1e is provided with a pin shaft hole 1 f.

In the embodiment, the block body is made of DC01 material and has a thickness of 3mm to meet the requirements of strength and rigidity.

In this embodiment, the gantry anti-roll stopper 1 is pressed and fixed on the gantry upper beam 3 by the fixing pin 2 through the pin shaft hole 1f, and the fixing pin 2 is pressed and fixed to prevent the gantry anti-roll stopper 1 from shaking and generating abnormal sound.

As shown in fig. 2, in this embodiment, the gantry anti-roll stopper 1 has a self-symmetric structure, so that the universality is good, the number of molds is reduced, the development cost is reduced, and meanwhile, the risk of manual missing installation is avoided.

As shown in fig. 4, when in use, two gantry anti-roll stoppers 1 are mounted on the gantry upper beam 3, so that an anti-roll function can be realized.

In this embodiment, as shown in fig. 3, when the gantry anti-roll stopper 1 is not in the anti-roll state, the gap d1 between the top surface 1b of the gantry anti-roll stopper 1 and the gantry top beam 3 is 4mm, and the gap between the first vertical surface 1a and the gantry top beam 3 and the gap d2 between the second vertical surface 1c and the gantry top beam 3 are 1 mm. Of course, the distances between d1 and d2 can be adjusted according to actual conditions.

In this embodiment, as shown in fig. 6, when the gantry anti-roll stopper 1 is in the anti-blocking state, the anti-blocking height d3 is 77mm, and of course, the height of d3 can be adjusted according to actual conditions.
