[0002] The jig frame is a kind of mold, which is mainly used for supporting and bearing, and is a kind of special process equipment for facilitating the assembly and welding of mechanical equipment, and is widely used in formwork engineering, steel structure installation engineering and bridge engineering. Different from the commonly used single and double row scaffolds, the jig frame has great differences in design due to the great differences in the supported structure form and weight. The form of the jig frame is also different due to different equipment and different processes.

[0003] When assembling the round pipe type component, the jig frame is basically fixed, the component is basically fixed after being placed on the jig frame, and the crane needs to be used again for turning operation after the upper part is assembled, which is low in production efficiency, and safety hazards are prone to occur due to the eccentricity of the component when turning. CONTENT OF THE INVENTION

[0004] In order to facilitate the quick turning of the round pipe type component during assembly, the present application provides a multifunctional rotating and assembling jig frame.

[0005] The present application provides a multifunctional rotating and assembling jig frame, which adopts the following technical scheme:

[0007] By adopting the above technical scheme, one round pipe type component is supported by two rotating and assembling jig frames, the round pipe type component is placed between the adjacent two roller assemblies of the rotating and assembling jig frame, and the adjacent two roller assemblies are used to support the round pipe type component. After adjusting the angle to start assembly, when the round pipe type component needs to be turned to change the assembly angle and position, the round pipe type component can be directly rotated, the round pipe type component only contacts with the contact wheel, the rotating resistance is small, and the rotation can be easily completed, so that the quick turning of the round pipe type component is facilitated.

[0008] Optionally, a wedge-shaped constraint block is detachably connected between the contact wheel and the fixed plate.

[0009] By adopting the technical scheme, the circular pipe type component is still prone to rotating during assembly after the angle of the circular pipe type component is adjusted, which causes certain influence on the assembly function. When the circular pipe type component does not need to rotate, the wedge-shaped restraint block is clamped between the contact wheel and the fixed plate to limit the rotation of the contact wheel, which helps to more stably perform the assembly work. When the circular pipe type component needs to be turned over, the restraint block is pulled out, and the rotating mode is restored.

[0014] Optionally, a first rib plate for enhancing support stability is fixedly connected between the steel leg and the steel base, the first rib plate is fixedly connected with the steel base perpendicularly, and the first rib plate is fixedly connected with the steel leg perpendicularly.

[0015] By adopting the technical scheme, the circular pipe type component has a large mass, the steel base and the steel leg are fixedly connected perpendicularly, and the stability is poor in the direction perpendicular to the connecting line. By arranging the first rib plate, the strength between the steel leg and the steel base is enhanced, and the support stability is enhanced.

[0017] By adopting the technical scheme, the gravity of the steel beam and the circular pipe type component all needs to be supported through the connecting part between the steel beam and the steel leg, the connecting part between the steel beam and the steel leg is prone to deformation, and by arranging the second rib plate, the connection strength between the steel beam and the steel leg is enhanced, and the support stability is enhanced.

[0018] Optionally, the steel beam is provided with a sliding rail, the length direction of the sliding rail is parallel to the length direction of the steel beam, the fixed plate is slidingly connected to the sliding rail, a threaded rod is provided on the fixed plate, the threaded rod is threadedly connected to the fixed plate, and the threaded rod is parallel to the length direction of the steel beam and rotationally connected to the steel beam.

[0019] By adopting the above technical scheme, the size of the round pipe type component is different, and two roller assembly with different intervals are needed to support the round pipe type component with different sizes, and the fixed plate is slidingly connected to the steel beam. The position of the roller assembly can be changed by rotating the threaded rod to drive the fixed plate to slide, and then the interval between the adjacent two roller assemblies is adjusted. When the rotation of the threaded rod is stopped, the sliding of the fixed plate is limited, and the position of the fixed plate is temporarily fixed. The rotating jig can adapt to more sizes of the round pipe type component, which helps to expand the application range.

[0020] Optionally, the threaded rod is provided with a rotating motor at one end, the rotating motor is fixedly connected to the steel beam, and the output shaft of the rotating motor is coaxially fixedly connected to the threaded rod.

[0021] By adopting the above technical scheme, the rotation of the threaded rod is driven by the rotating motor, which helps to improve the position adjustment speed of the fixed plate and can save some labor.

[0022] In summary, the present application has at least one of the following beneficial technical effects:

[0023] 1. Two rotating jigs are matched to support the round pipe type component, the round pipe type component is placed between the adjacent two roller assemblies, and the round pipe type component is supported by two contact wheels at each end. When it is needed to turn the round pipe type component to change the assembly angle and position, the round pipe type component can be directly rotated. The round pipe type component only contacts with the contact wheel, the rotation resistance is small, and the rotation can be easily completed, which is convenient for realizing the quick turning of the round pipe type component.

[0024] 2. During the assembly of the round pipe type component, the round pipe type component is prone to rotate, which affects the assembly function. When the round pipe type component does not need to be rotated, the restraint block is clamped between the contact wheel and the fixed plate to limit the rotation of the contact wheel, which helps to more stably perform the assembly work. When the round pipe type component needs to be turned over, the restraint block is pulled out, and the rotation mode is restored. BRIEF DESCRIPTION OF DRAWINGS
