Description

Technical Field

[0001] The invention belongs to the field of enclosure installation, and in particular relates to a highway construction enclosure hoisting and installation device. Background Art

[0002] During road widening or reconstruction and highway maintenance, fences are installed to isolate the construction area and guide vehicles and pedestrians. For fences of larger quantity and size, flatbed trucks or vans are used for transportation. After arriving at the fence installation area, the fence is unloaded by manual handling or mechanical assisted handling. For fences of larger size, manual handling is inefficient, inconvenient and unsafe, so mechanical assisted handling is more common. Mechanical assistance usually uses a crane to hoist and unload the fence. When a crane is used to hoist the fence, since the fence itself does not have a part for the hook to hang directly, ropes must be used to tie the baffles before hoisting. During the hoisting process, the crane is in the shape of a plate as a whole, which is easily affected by the wind and shakes. The stability is poor during hoisting, and the fence cannot be accurately kept vertically dropped for installation, which increases the difficulty of installation and reduces construction efficiency.

[0003] In view of the above problems existing in the installation of fences, the present application proposes a highway construction fence lifting and installation device. Summary of the invention

[0038] Working principle: In the initial state, Figure 1-Figure 3 As shown, under the action of the spring 30 and the torsion spring, the end of the support arm 11 away from the swing shaft 8 rotates to the position closest to the main plate 5; the rack 10 drives the trigger block 21 to slide to a position away from the horizontal plate 6; the sliding seat 13 slides to a position close to the horizontal plate 6; the sliding arm 15 slides to the front end of the sliding groove 16 and contacts the limiting column 17. At this time, a gap is maintained between the trigger rod 20 and the main plate 5, and the gap corresponds to the upper end of the trigger block 21. An angle is formed between the limiting plate 14 as a whole and the main plate 5. The deflection plate 24 is close to a horizontal state at this time, and the end of the deflection plate 24 away from the rotating ear seat 18 contacts the trigger rod 20, and the trigger reset rod 25 abuts against the rear side of the main plate 5.

[0039] When lifting, the lifting ring 7 is always mounted on the hook 2 of the crane 1, and then the crane 1 is controlled to move the present application to the position directly above the enclosure 3, and then the reinforcement frame 4 on the back of the enclosure 3 is hung on the two support wheels 12, and then the enclosure 3 is lifted upward, and the support arm 11 and the swing shaft 8 rotate under the gravity of the enclosure 3, driving the rack 10 to slide upward under the left and right sides of the gear 9, and while the support arm 11 rotates, the support wheels 12 extend to both sides of the enclosure 3 until they are at two right angles to the upper end of the enclosure 3. In this process, the sliding seat 1 is moved under the left and right sides of the rope 35. 3 slides downward, the spring 30 is stretched; at the same time, the upper end of the trigger block 21 enters the gap between the trigger rod 20 and the main plate 5, as the trigger plate follows the rise of the rack 10 and the sliding seat 13 slides downward, the inclined surface 22 of the trigger block 21 drives the trigger rod 20 to move away from the main plate 5, drives the sliding arm 15 to move so that the limit plate 14 moves toward the main plate 5, and then the upper end of the trigger block 21 pushes the deflection plate 24 to rotate the limit plate 14 and the rotating ear seat 18 until the limit plate 14 rotates to a vertical state and is pressed against the front side of the enclosure 3. At this time, the enclosure 3 is in a suspended state as a whole and maintains a vertical and stable state. After the crane 1 is operated to move to the placement position of the enclosure 3, the enclosure 3 is lowered. When the enclosure 3 falls to the ground, as the device is gradually no longer affected by the gravity of the enclosure 3 and as the hook 2 drives the device to continue to descend, under the action of the spring 30 and the torsion spring, the device returns to its initial state. Subsequently, the crane 1 is moved to move the device toward the rear of the enclosure 3 and then upward to complete the complete separation of the device from the enclosure 3.
