Abstract

The invention discloses a clamp for an I beam and belongs to the technical field of the design of hoisting devices. The clamp comprises two clamp claws, a locking shaft, a handle, a hinge pin, clamp claw grooves, the I beam and a locking seat. The two clamp claws are fixedly connected through the hinge pin. The locking seat is arranged in the middle of the clamp claws in the front-back direction. A threaded hole is formed in the locking seat. The locking shaft is a straight rod thick at the left end and thin at the right end. An external thread is machined on the thin rod portion on the right side of the locking shaft. The external thread of the locking shaft is screwed in the threaded hole of the locking seat. The distance between clamping feet at the tops of the two clamp claws can be adjusted conveniently by rotating the locking shaft, and thus the I beam is clamped. The clamp for the I beam is simple in structure, convenient to operate and low in cost, the I beam is clamped reliably, the weight of the clamp claws is low, the ends of the clamp claw grooves are of arc-shaped concave structures, and after the I beam is clamped, the I beam is suspended stably when hoisted through the arc-shaped concave structures.

Description

A kind of I-beam clamp
Technical field
The present invention relates to chain sling design field, particularly relate to a kind of I-beam folder Pincers.
Background technology
In the middle of mechanical industry and daily life, we it is frequently necessary to carry out at certain interval range The carrying work of girder beam, owing to the weight of I-beam is too big, uses traditional artificial side Formula can cause the labour intensity of workman big, and handling efficiency is low, the I-beam clamp used in the past by In the existing defects when structure designs, lifting efficiency is low, and labor strength is big, troublesome poeration, The situation that I-beam the most even can be occurred to drop during transporting, causes great safety to ask Topic, some clamp uses solid construction, and chela weight is big, therefore the letter of a kind of structure of design Single, easy to operate, low cost, I-beam clamp is reliable, chela lightweight, and I-beam hangs Hang stable I-beam clamp 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, and troublesome poeration is dangerous, the defect that chela weight is big, devises a kind of I-beam folder Pincers, simple in construction, lightweight, easy to operate, low cost, 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 clamp, including chela, bearing pin, described chela is provided with two altogether, and two Use described bearing pin to connect described in root between chela fixing, also include lock shaft, handle, chela Groove, locking bed, the centre position fore-and-aft direction at described chela is provided with described locking bed, institute Stating and be drilled with screwed hole on locking bed, described lock shaft is a left thick right thin straight-bar, thin on the right side of it Bar is machined with external screw thread, and the external screw thread of described lock shaft i.e. screws the screwed hole at described locking bed In.
The bottom inside of described chela is machined with described chela groove.
The main body of described chela is made for two block plates front and back, and described locking bed is i.e. arranged on two pieces Between steel plate.
Described chela uses low-carbon (LC) superior alloy steel to make.
The end of described chela groove is arc concave shape structure.
Owing to have employed above technical scheme, present invention have the advantage that
Chela, bearing pin, lock shaft, handle, chela groove, locking bed is used to combine designed I-beam clamp, the bottom inside of chela is machined with chela groove, during clamping I-beam, by work The steel plate two ends of word beam are respectively embedded in the chela groove of two chelas, and I-beam clamp is reliable, pincers The main body of pawl is made for two block plates front and back, and locking bed is i.e. arranged between two block plates, chela Lightweight, chela use low-carbon (LC) superior alloy steel make, low price, low cost, chela The end of groove is arc concave shape structure, and after I-beam is clamped, its arc concave shape structure makes work Hang steadily when word beam is lifted.

Fig. 2 is present configuration left view schematic diagram;
In figure each assembly and reference be respectively as follows: 1, chela;2, lock shaft;3, handle; 4, bearing pin;5, chela groove;6, I-beam;7, locking bed.
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 clamp, including chela 1, lock shaft 2, handle 3, bearing pin 4, chela Groove 5, I-beam 6, locking bed 7, chela 1 is provided with two altogether, between two chelas 1 Using bearing pin 4 to connect fixing, the centre position fore-and-aft direction at chela 1 is provided with locking bed 7, Being drilled with screwed hole on locking bed 7, lock shaft 2 is a left thick right thin straight-bar, thin bar on the right side of it Being machined with external screw thread, this external screw thread i.e. screws in the screwed hole of locking bed 7, rotation lock axle 2 can be conveniently adjusted the distance bottom two chelas 1 between card base, it is achieved by I-beam 6 Clamping, this apparatus structure is simple, easy to operate, low cost.
The bottom inside of chela 1 is machined with chela groove 5, during clamping I-beam 6, by I-beam The steel plate two ends of 6 are respectively embedded in the chela groove 5 of two chelas 1, I-beam 6 reliable clamping.
The main body of chela 1 is made for two block plates front and back, and locking bed 7 is i.e. arranged on two block plates Between, chela 1 lightweight.
Chela 1 uses low-carbon (LC) superior alloy steel to make, low price, low cost.
The end of chela groove 5 is arc concave shape structure, after I-beam 6 is clamped, in its arc Hang steadily when recessed structure makes I-beam 6 be lifted.
I-beam clamp disclosed in this invention, the bottom inside of chela 1 is machined with chela groove 5, During clamping I-beam 6, the steel plate two ends of I-beam 6 are respectively embedded into the chela of two chelas 1 In groove 5, I-beam 6 reliable clamping, the main body of chela 1 is made for two block plates front and back, locks Tight seat 7 is i.e. arranged between two block plates, chela 1 lightweight, and chela 1 uses low-carbon (LC) excellent Matter steel alloy makes, low price, low cost, and the end of chela groove 5 is arc concave shape structure, After I-beam 6 is clamped, hang steadily when its arc concave shape structure makes I-beam 6 be lifted.
