Compared with the prior art, the beneficial effects of the utility model are that: according to the semitrailer portal frame, the length and the position of the side pull rod can be flexibly adjusted through the structure of the side pull rod and the telescopic sleeve, so that the semitrailer portal frame can be used for matching goods of different specifications and volumes; through the structure that sets up safety rope and mounting, can strengthen the security of device, improve the design safety margin of whole equipment.
Drawings
Fig. 1 is a schematic structural view of the present invention;
fig. 2 is a side sectional view of the present invention.
In the figure: the gantry comprises a gantry body 1, a grid framework 11, a gantry body 2, a side pull rod 3, a telescopic sleeve 31, a fastening bolt 32, a second fixing piece 4, a movable clamping piece 41, a safety rope 42, a first fixing piece 43, a hinged frame 5 and a one-way gear 51.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-2, the present invention provides a technical solution: a semitrailer portal frame comprises a portal frame body 1 and a bottom plate 2, wherein a grid framework 11 is arranged in the middle of the portal frame body 1, the grid framework 11 is an I-shaped steel frame, an anti-rust layer is sprayed on the surface of the grid framework 11, the grid framework has high structural strength and good anti-rust capability and has long service life, two sides of the upper end of the portal frame body 2 are respectively provided with a hinged frame 5, the hinged frames 5 are respectively provided with a one-way gear 51, each hinged frame 5 is a steel frame and is provided with a clamping hole and a clamping buckle, the binding ropes are used for matching different structures and materials and are used for stabilizing goods and rainproof tarpaulins, the left side and the right side of the portal frame body 1 are respectively provided with a side pull rod 3 through a fastening bolt 32, the middle section of each side pull rod 3 is provided with an expansion sleeve 31, each side pull rod 3 comprises an upper support rod and a lower support rod, the 2 support rods are movably hinged through, the tail end of the side pull rod 3 is fixed on the side wall of the bottom plate 2, the upper part of the portal frame body 1 is provided with a first fixing piece 43, the lower end of the first fixing member 43 is provided with at least three safety ropes 42, the safety rope 42 is a steel twisted rope, the safety rope 42 is embedded in the bottom plate 2 through the movable clamping piece 41, the tail end of the safety rope 42 is fixed in the bottom plate 2 through a second fixing piece 4, the bottom end of the safety rope 42 is buried in the bottom plate 2 to a depth of more than 1cm, the depth of the movable clamping piece 41 and the second fixing piece 4 embedded in the bottom plate 2 exceeds 2cm, when goods slide, once the portal frame body 1 is bent or inclined forwards, the safety rope 42 will bounce the movable clamping piece 41, therefore, the portal frame body 1 and the bottom plate 2 are connected, a stable triangle is formed, a higher safety margin is obtained, and a reinforcing plate 21 is arranged at the joint of the portal frame body 1 and the bottom plate 2.
