Clamping part 1200.
This stone tongs, which provokes wirerope just merely with fork truck, can complete the lifting operation of guardrail, without employing large-scale rise
Heavy equipment, cost are lower.
<embodiment two>
As shown in figure 3, the stone tongs in the present embodiment is compared to above-described embodiment, the difference is that, the power-assisted
The both ends of spring 1500 are individually fixed in the force section 1100 of the left caliper 1010 and the force section of the right caliper body 1020
1100。
So that this stone tongs, after reaching Hoisting Position, jaw is under the action of power assistant spring 1500 in preload shape
State pre-tightens without artificial, facilitates lifting, and do not do preload movement manually during lifting, lifts by crane safer.
<embodiment three>
As shown in figure 4, the stone tongs in the present embodiment is on the basis of example 1, it is provided on the caliper 1000
Several hinge holes 1600, link bolt 1610 pass through the hinge hole 1600 and the right caliper body 1020 of the left caliper 1010
The hinge hole 1600 of same position is hinged by the left caliper 1010 and the right caliper body 1020.
As shown in figure 5, the scheme in the present embodiment can pass through different hinge holes 1600 according to the difference of guardrail specification
Hingedly, the size of jaw is adjusted, the use scope of this stone tongs is expanded.
<example IV>
As shown in fig. 6, the stone tongs in the present embodiment, on the basis of example 1, the hinge of the left caliper 1010
The place of connecing is fixed with articulated shaft (not shown), and one end of the articulated shaft is fixed with ratchet 1710, and the right caliper body 1020 is cut with scissors
It is connected on the articulated shaft between the left caliper 1010 and the ratchet 1710, is provided on the right caliper body 1020 and the spine
The lock pawl 1720 that wheel 1710 matches.Stone tongs is in clamping process, locked to the position of caliper 1000, prevents it because trembling
The dynamic or inertia that rises and open, cause guardrail to fall.
In the present embodiment, 1720 upper end of lock pawl is fixed with motion bar 1721, is used for the lock pawl 1720
The ratchet 1710 is removed, after the completion of lifting, convenient for opening fixture, discharges guardrail.Lock pawl 1720 passes through torsional spring elastic connection
In on right caliper body 1020, lock pawl 1720 is enabled to be caught in ratchet 1710 under the elastic force of torsional spring, prevented because of shake so that only
Pawl 1720 removes ratchet 1710, causes danger.
The program of the present embodiment further enhances the safety of guardrail stone tongs.
Although being described in detail by some specific embodiments of the example to the utility model, this field
It is to be understood by the skilled artisans that above example merely to be illustrated, rather than in order to limit the scope of the utility model.This
Field it is to be understood by the skilled artisans that can not depart from the scope of the utility model and spirit in the case where, to above embodiments
