Abstract
The invention discloses an I-shaped beam hoisting tong and belongs to the technical field of hoisting device design. The I-shaped beam hoisting tong comprises a tong body, a tong claw, a pin shaft, a hoisting hole, a hoisting rope and an I-shaped beam. The tong body and the tong claw are connected through the pin shaft to form a rotation pair. The hoisting hole is formed in the top end of the tong body. When the I-shaped beam is hoisted, the hoisting rope penetrates through the hoisting hole in the top end of the tong body, the I-shaped beam is clamped between the left side face of the tong claw and the working face of the tong body, and the I-shaped beam can be hoisted and conveyed to a required position by pulling the hoisting rope. During hoisting, two hoisting tongs are simultaneously used. The I-shaped beam hoisting tong disclosed by the invention is simple in structure and low in cost, hoisting is convenient, mounting of the tong claw is reliable, and the tong claw rotates flexibly. Clamping force applied to the I-shaped beam is large, clamping is reliable, and the tong body and the tong claw are low in price.

Putting due to the existing defects when structure designs, lifting efficiency is low, and labor strength is big, operation
Trouble, the situation that I-beam the most even can be occurred to drop during transporting, causes great peace
Full problem, therefore a kind of simple in construction of design, lifting is convenient, low cost, and chela is installed reliable,
Rotating flexibly, clamping force suffered by I-beam is big, and reliable clamping, caliper and chela are low-cost
I-beam crane pincers are the most necessary.
Summary of the invention
The purpose of the present invention is contemplated to overcome former I-beam boom hoisting workman to work by force
Degree is big, troublesome poeration, unsafe defect, devises a kind of I-beam crane pincers, structure letter
Single, lifting is convenient, low cost, and chela rotates flexibly, and I-beam clamp is reliable.
Solve the technical problem that required by the present invention and can be achieved through the following technical solutions:
A kind of I-beam crane pincers, including caliper, chela, bearing pin, described caliper and described pincers
Use described bearing pin to connect between pawl and form revolute pair, also include lifting hole(eyelet), lifting rope, described caliper
Top be machined with described lifting hole(eyelet), described lifting rope is through the described lifting hole(eyelet) on described caliper top, work
Word beam is then sandwiched between the left surface of described chela and the working face of described caliper, described lifting rope
It is pulled up and I-beam can be lifted by crane and be transported to desired location, during lifting, use two simultaneously
Hoisting tongs.
The bottom of described caliper is machined with the gap slot of fore-and-aft direction, and the described caliper in right side compares left side
Greatly, the bottom of the described caliper in right side is machined with the gap slot of a left and right directions, and described chela is pacified
It is contained in the gap slot of this left and right directions.
The shape of described chela is similar to the shape of ratchet, and its arc shape is near parabolic.
The working face of described caliper is machined with caliper tooth.
Described caliper and described chela are low-carbon (LC) superior alloy steel and make.
Owing to have employed above technical scheme, present invention have the advantage that
Caliper, chela, bearing pin, lifting hole(eyelet), lifting rope is used to combine designed I-beam crane
Pincers, the bottom of caliper is machined with the gap slot of fore-and-aft direction, and right side caliper is bigger than left side, right side
The bottom of caliper is machined with the gap slot of a left and right directions, and chela is installed reliable, rotates flexibly,
The shape of chela is similar to the shape of ratchet, and its arc shape is near parabolic, I-beam institute
Big by clamping force, reliable clamping, the working face of caliper is machined with caliper tooth, works as caliper
Can increase the frictional force between itself and I-beam side during clamping I-beam, I-beam clamp can
Leaning on, caliper and chela are low-carbon (LC) superior alloy steel and make, low price, low cost.
Accompanying drawing explanation
Fig. 1 is present configuration front-view schematic diagram；
Fig. 2 is that the present invention lifts by crane I-beam schematic diagram；
In figure each assembly and reference be respectively as follows: 1, caliper；2, chela；3, bearing pin；4、
Lifting hole(eyelet)；5, lifting rope；6, I-beam.
Detailed description of the invention
For the technological means making the present invention realize, creation characteristic, reach purpose and be prone to effect
Understand and understand, below in conjunction with being specifically illustrating, the present invention is expanded on further.
A kind of I-beam crane pincers, including caliper 1, chela 2, bearing pin 3, lifting hole(eyelet) 4, lifting rope
5, I-beam 6, use bearing pin 3 to be connected formation revolute pair, pincers between caliper 1 with chela 2
The top of body 1 is machined with lifting hole(eyelet) 4, and during lifting I-beam 6, lifting rope 5 is through caliper 1 top
Lifting hole(eyelet) 4, I-beam 6 is then sandwiched between the left surface of chela 2 and the working face of caliper 1,
Lifting rope 5 is pulled up and I-beam 6 can be lifted by crane and is transported to desired location, during lifting, simultaneously
Using two hoisting tongs, I-beam 6 lifts by crane steadily, this hoisting tongs simple in construction, and lifting is convenient,
Low cost.
The bottom of caliper 1 is machined with the gap slot of fore-and-aft direction, and right side caliper is bigger than left side, right
The bottom of side caliper is machined with the gap slot of a left and right directions, and chela 2 is arranged on this right and left
To gap slot in, install reliable, rotate flexibly.
The shape of chela 2 is similar to the shape of ratchet, and its arc shape is near parabolic, work
Word beam 6 inserts between chela 2 and caliper 1, along with moving down of I-beam 6, chela 2 and pincers
The extruding force of body 1 is gradually increased, and clamping force suffered by I-beam 6 is big, reliable clamping.
