Detailed Description

The present invention will be further explained with reference to the accompanying drawings and specific embodiments:

concrete embodiment is shown in fig. 1 to fig. 6, the utility model relates to a road engineering installation is with supplementary elevating gear, including chain block 1 and the hoist of being connected with chain block 1 lifting end, still include folding support, folding support is including two sets of articulated arms 2 of articulated setting, the lower extreme of articulated arm 2 is provided with two sets of scissors form articulated bracing pieces 3 that are, bracing piece 3 is the pin joint setting of rectangular pyramid structure around two sets of articulated arms 2, be provided with hole for hoist 4 on the articulated arm 2.

The utility model discloses when using, open bracing piece 3 respectively, and unscrew two sets of articulated arm 2 and be the scissors form, make folding support expand and erect on the installation foundation ditch, overlap the hoist cover on the lift post, be connected chain block 1 with the hoist, chain block 1 hangs on articulated arm 2 through hoisting hole 4, support as hoist and mount through the rectangular pyramid structure's that folding support formed support frame, pull up the lift post with the help of chain block 1, supplementary chain block 1 goes up and down the lift post, the personnel of being convenient for adjust the grit packing condition of lift bottom of the column in the foundation ditch, the security when having improved the installation of lift post in the road construction.

Further, as shown in fig. 2 and 5, the lower ends of the support rods 3 are provided with drawknot holes 5, and a hauling rope 6 is arranged in the drawknot hole 5 between the adjacent support rods 3.

After the folding support is unfolded, the support rod 3 forms a stable triangular support structure through the traction of the traction rope 6, and the safety during hoisting is ensured.

Furthermore, the installation of the lifting column belongs to a part of road engineering, and at the moment, the toll collection channel of the toll station only completes foundation compaction, and the asphalt pavement is not paved, and at the moment, the lower end of the support rod 3 is provided with a conical foundation cone 7. Insert the ground after the compaction through lower margin awl 7, can play the effect of stabilizing folding support structure to the higher bracing piece 3 of just this moment of ground intensity is the tilt state, and lower margin awl 7 is unlikely to go into ground too deeply, has guaranteed folding support's safe handling.

Further, the hoist be ring shaped structure, including two sets of semicircular ring shape hoist and mount pieces 8 that the symmetry set up, the outer loop side of hoist and mount piece 8 is provided with rings 9, form with the help of grafting structure between the hoist and mount piece 8 and can dismantle the connection.
