Embodiment 1

[0020] Embodiment one: Figure 1 to Figure 4 As shown, a self-loading and unloading hoisting mechanism mounted on a semi-trailer includes a semi-trailer chassis 10, and a hoisting mechanism 20 is respectively installed at both ends of the semi-trailer chassis 10. The hoisting mechanism 20 includes: a base 1, a lower part of the base 1 clamped on the beam 101 of the semi-trailer chassis 10;

[0021] A telescopic crane assembly 2 is arranged in the middle of the upper part of the base 1. The telescopic crane assembly 2 includes a swing arm 21, a telescopic arm 22, and a telescopic arm cylinder 23. The telescopic arm 22 is sleeved on the swing arm 21, and the telescopic boom cylinder 23 The tail is hinged on the inner bottom of the swing arm 21, the piston rod of the telescopic arm cylinder 23 is hinged on the telescopic arm 22, the bottom of the swing arm 21 is hinged to the base 1, and the middle and upper sides of the swing arm 21 are connected to the base by swing cylinders 2...

Embodiment 2

[0025] Embodiment two, Figure 5 to Figure 7 As shown, it is different from Embodiment 1 in that a gantry-type support arm assembly 3 is not installed on both sides of the front and rear ends of the semi-trailer chassis 10, but instead a support arm assembly is installed on both sides of the top of the base 1, and the two support arms One of the components is a bridge leg type support arm assembly 7, and the other is a telescopic support arm assembly 8;

[0026] The bridge leg type support arm assembly 7 includes an inner arm 71, an inner arm oil cylinder 72, a support leg 73, and a support leg oil cylinder 74. The lower end of the inner arm 71 is hinged on one side of the base 1, and the cylinder tail of the inner arm oil cylinder 72 is hinged on the base 1, the front end of the inner arm oil cylinder 72 piston rod is hinged to the middle of the inner arm 71, the rear end of the support leg 73 is hinged to the front end of the inner arm 71, and the tail of the support leg oil...

Abstract

The invention discloses a self-loading and unloading hoisting mechanism arranged on a semi-trailer, wherein the self-loading and unloading hoisting mechanism comprises a semi-trailer chassis. Hoisting mechanisms are respectively arranged on both ends of the semi-trailer chassis. Each hoisting mechanism comprises a base;; a telescopic hoisting component arranged in the middle of the upper part of the base;; and gantry type supporting arm components arranged on both sides of the front end and the back end of the semi-trailer chassis or supporting arm components respectively arranged on both sides of the upper part of the base, wherein both sides of the lower part of the base are clamped on a cross beam of the semi-trailer chassis; the telescopic hoisting component comprises a swinging arm, a telescopic arm and a telescopic arm oil cylinder; the telescopic arm is sleeved on the swinging arm and is connected with the swinging arm through the telescopic arm oil cylinder; the lower part of the swinging arm is hinged with the base; both sides of the middle upper part of the swinging arm are hinged with both sides of the upper part of the base through swinging oil cylinders; a hoisting component is arranged at the upper end of the telescopic arm The self-loading and unloading hoisting mechanism realizes goods self-loading and unloading on both sides of the semi-trailer chassis, is simple in structure, effectively reduces the number of semi-trailers arranged on a tractor, increases the transportation efficiency and reduces the transportation cost.

Description

technical field [0001] The invention relates to a hoisting device mounted on a transport vehicle, in particular to a self-loading and unloading hoisting mechanism mounted on a semi-trailer. Background technique [0002] In order to enable semi-trailers to load and unload containers by themselves, reduce the number of tractors equipped with semi-trailers, and reduce the investment and transportation costs of logistics companies, people have begun to develop self-loading and unloading lifting equipment on semi-trailers. For example, on May 19, 2010, a public The patent number is ZL200920224422.1, and the invention patent named "Container Trailer Self-Loading and Unloading Mechanism" includes front and rear folding arm cranes installed symmetrically at the front and rear ends of the container trailer, the front folding arm crane and the The rear knuckle crane group has a base on which the knuckle crane and the support arm are installed. A turn lock matching the bottom hole of t...
