Detailed Description
The following further describes the embodiments with reference to the drawings.
Example (b):
as shown in fig. 1 to 4, a lifting appliance for a prefabricated guardrail comprises a rectangular frame beam, a lifting mechanism arranged on the rectangular frame beam, and a fixing mechanism arranged at the lower end of the rectangular frame beam;
fixed establishment includes a plurality of and rectangular frame roof beam sliding connection's fixed subassembly, runs through whole fixed subassembly's screw rod 1, the both ends of screw rod 1 are equipped with nut 2, fixed subassembly include with rectangular frame roof beam sliding connection's fixed frame 3, be fixed in fixed block 4 in fixed frame 3, fixed frame 3 is perpendicular with the rectangular frame roof beam. Be equipped with lewis hole 5 on the fixed block 4, screw rod 1 is inserted and is located lewis hole 5, is equipped with preformed hole 7 on the prefabricated guardrail 6, has all placed a prefabricated guardrail 6 between every adjacent fixed block 4, and screw rod 1 runs through lewis hole 5 and preformed hole 7 in proper order, and with fixed block 4 and the 6 strings of prefabricated guardrail on screw rod 1, 1 both ends of screw rod are fixed with nut 2 respectively, make screw rod 1 can not deviate from, the both sides of fixed block 4 and 5 inside rubber pads that all are equipped with of lewis hole, the setting of rubber pad can prevent the collision between fixed block 4 and the prefabricated guardrail 6, and the damage is avoided to protection prefabricated guardrail 6.
