Description

Hoisting accessory for internal welding machine

Technical Field

The utility model relates to an attachment structure of interior welding machine, concretely relates to hoisting accessory for interior welding machine.

Background

As shown in fig. 1, a front part 1 and a rear part 6 of an internal welding machine of the internal welding machine on the market are connected through a universal coupling 4 and a lifting device 3, and a spring mechanism 5 is arranged between the two parts; the hoisting device 3 is used for providing a hoisting position for the inner welding machine and cannot limit the relative freedom degree of the front part and the rear part of the inner welding machine; as shown in figure 2, the conventional general hoisting device is characterized in that a hoisting beam 3-1 is hinged with a front frame 10 of a front part 1 of an inner welding machine, the hoisting beam 3-1 is hinged with a connecting plate 3-5 through a pin shaft I3-4, the connecting plate 3-5 is hinged with a rear frame 9 through a pin shaft II 3-6, and the front part 1 of the inner welding machine is hinged with a rear part 6 of the inner welding machine through a universal coupling 4; therefore, the 4 hinge points form an unstable quadrilateral structure, and the degree of freedom must be limited by a locking device during lifting; the locking device needs to be removed after the lifting, but the locking device is troublesome in alignment, once the locking device is not locked, the degree of freedom of the locking device cannot be limited, the relative movement of the front part and the rear part of the inner welding machine can cause large-amplitude shaking of the inner welding machine in the lifting process of the inner welding machine, and other parts of the inner welding machine are easily damaged. Therefore, locking devices are additionally arranged at the front part and the rear part of the inner welding machine, the front part and the rear part are locked in the hoisting process, and the devices are dismantled after the hoisting is finished; this increases the inconvenience of using the device in the field.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model aims at providing an interior hoisting accessory for welding machine.

The utility model adopts the following technical scheme for accomplishing the above purpose:

a hoisting device for an internal welding machine is provided with a hoisting beam hinged with a front frame at the front part of the internal welding machine; the non-hinged end of the lifting beam and the front frame is provided with a fixed block extending towards one side; the fixed block is sleeved with a slide block which can horizontally slide along the fixed block; the lower part of the sliding block is hinged with a rear frame at the rear part of the internal welding machine through a pin shaft II; the sliding block and the fixed block are matched to form a sliding pair which is used for enabling the front part of the inner welding machine and the rear part of the inner welding machine to relatively slide; and the sliding block is provided with a locking screw used for limiting the relative sliding of the front part of the inner welding machine and the rear part of the inner welding machine.

The sliding block is provided with a hollow block sleeved on the fixed block and two support legs positioned at the lower part of the hollow block; and the two support legs are hinged with a rear frame at the rear part of the inner welding machine through a pin shaft II.

And a limiting plate used for limiting the movement of the sliding block is arranged at the end of the fixed block corresponding to the sliding block.

The utility model provides an interior hoisting accessory for welding machine, it is vice through the slip that sets up fixed block and slider on the lifting beam, when welding machine normal use including, locking screw does not compress tightly the lifting beam, the degree of freedom of interior welding machine front portion and interior welding machine back part is unrestricted equally, compress tightly the lifting beam with locking screw when the handling, slider and lifting beam can not produce relative slip this moment, with the relative degree of freedom of this restriction interior welding machine front portion and interior welding machine back part, in order to realize steadily the handling, the convenient to use nature of equipment has been increased.

In the figure: the welding machine comprises an inner welding machine front portion 1, a locking device 2, a lifting device 3, a lifting beam 3-3, a fixed block 3-2, a lifting plate 3-4 pin shafts I and 3-5, a connecting plate 3-6, pin shafts II and 3-7, a sliding block 3-8, pin shafts III and 3-9, pin shafts IV and 3-10, a limiting plate 3-11, locking screws 4, a universal coupling 5, a spring mechanism 6, an inner welding machine rear portion 7, a rear frame 8 and a front frame.

Detailed Description

The invention will be described in conjunction with the drawings and the embodiments

As shown in fig. 3, 4 and 5, the hoisting device for the internal welding machine is provided with a hoisting beam 3-1 hinged with a front frame 8 of a front part 1 of the internal welding machine; the non-hinged end of the lifting beam 3-1 and the front frame 8 is provided with a fixed block 3-3 extending to one side; the fixed block 3-3 is sleeved with a slide block 3-7 which can horizontally slide along the fixed block; the lower part of the sliding block 3-7 is hinged with a rear frame 7 at the rear part of the internal welding machine through a pin shaft II 3-6; the sliding block 3-7 is matched with the fixed block 3-3 to form a sliding pair which is used for enabling the front part of the inner welding machine and the rear part of the inner welding machine to relatively slide; and locking screws 3-11 for limiting the relative sliding of the front part and the rear part of the inner welding machine are arranged on the sliding blocks 3-7.

Referring to fig. 5, the sliding blocks 3 to 7 have a hollow block sleeved on the fixed block and two supporting legs located at the lower part of the hollow block; the two support legs are hinged with a rear frame 7 at the rear part of the inner welding machine through pin shafts II 3-6.

And limiting plates 3-10 for limiting the movement of the sliding blocks are arranged at the ends of the fixed blocks corresponding to the sliding blocks 3-7.

When the internal welding machine is normally used, the locking screws 3-11 do not press the lifting beam, the freedom degrees of the front part 1 of the internal welding machine and the rear part 6 of the internal welding machine are not limited, the locking screws 3-11 press the lifting beam in the lifting process, and the sliding block and the lifting beam cannot slide relatively at the moment, so that the relative freedom degrees of the front part and the rear part of the internal welding machine are limited, the stable lifting is realized, and the use convenience of the equipment is improved.
