The hinged adjustment structure realizes that when the support frame is raised and lowered at one end or both ends at the same time, it prevents the long rod goods from sliding on the support rack. The long rod goods rely on their own gravity to find a suitable center of gravity on the support rack. There will be no angle between the racks, so that the two are always in face-to-face contact, ensuring that the long rods are evenly stressed.

The mechanism and the translation mechanism are connected through a hinge adjustment mechanism.

The lifting mechanism includes a vertical column outer tube, a column inner tube axially slidably connected to the column outer tube, and a lifting hydraulic cylinder inside the column inner tube.

The translation mechanism includes a horizontally arranged upper beam inner tube, the lower part of the upper beam inner tube is hinged to the piston rod on the top of the lifting hydraulic cylinder through a hinged adjustment structure, and the upper beam outer tube is axially slidably connected to the outer tube of the upper beam inner tube , the bottom of the outer tube of the upper beam is axially opened with a long hole for the axial movement of the hinged adjustment structure, and the inner tube of the upper beam is provided with a translation hydraulic cylinder, the rear end of the translation hydraulic cylinder is hinged with the inner tube of the upper beam, and the front end of the translation hydraulic cylinder The piston rod is hinged with the outer tube of the upper beam through the connecting block.

The hinge adjustment structure includes a pin shaft supported on the inner tube of the column at both ends, and a connector is hinged on the pin shaft. The pin shaft is fixedly connected with the piston rod of the lifting hydraulic cylinder, and the connector is fixedly connected with the inner tube of the upper beam.

The support frame includes two support vertical plates that are vertically arranged on the upper end of the upper beam outer tube edge, a support slant plate is provided between the top of the support vertical plate and the upper beam outer tube, and a suspension hook is provided outside the support vertical plate.

By adopting the above-mentioned technical scheme, the following beneficial effects can be achieved:

1. The hinged adjustment structure realizes that when the support frame is raised and lowered at one end or both ends at the same time, it prevents the long rod goods from sliding on the support rack. The long rod goods rely on their own gravity to find a suitable center of gravity on the support rack, and the long rod goods There will be no angle with the support frame, so that the two are always in surface-to-surface contact, ensuring that the long rods are evenly stressed.

2. Both the lifting mechanism and the translation mechanism adopt the principle of hydraulic power transmission and relative sliding to realize the lifting and horizontal translation of long rods, so as to improve the passing capacity under complex road conditions.

3. The long-stem goods are placed between the two support slant plates, the stability is better, the support vertical plate plays a good supporting role, and the hook plays the role of the rope when the rope is tied to the long-stem goods.

A loading and fixing method is adopted, which is more convenient and quicker for loading and unloading. When transporting long pole goods in mountainous areas and forest areas, when going up the mountain, the front end operates the rear two lifting hydraulic cylinders 5 to lift, so that the front and rear can be kept level to prevent the long pole goods from sliding down; when the road surface is uneven, the front and rear can be adjusted Two translational hydraulic cylinders 10 realize the movement of the center of gravity of the long-bar goods. The hinged adjustment structure realizes that when the support slant plate 16 is raised and lowered at one end or both ends at the same time, the long bar goods will not slide on the support slant plate 16, and the long bar goods rely on their own gravity to find a suitable center of gravity on the support slant plate 16.
