Description
Technical Field
The utility model relates to the technical field of waste heat boilers, in particular to a connecting and fixing device for a heated duct piece and an external header of a waste heat boiler.
Background
In the installation process of the waste heat boiler, a large amount of field butt welding workload exists in the connection between the heated pipe pieces and the header, the length of a pipeline at the side of the header is generally 80-100mm, the position of the nearest elbow of the pipeline is 500mm away from the port 300, the pipeline is arranged densely, the upper and lower layers of heated pipe pieces are within 150mm, and the operation space is limited.
At present, the existing connecting device adopts butt tongs, and when in welding, the duct piece is heated, so that certain deformation is inevitably caused in the manufacturing, transporting and installing processes. However, the two sections of pipes are clamped by the jaws, the width of the two ends of the jaws is short, so that the force is not enough to correct the deformation of the short pipe, and the handles are long, so that the requirements on the operation space are high. Therefore, the efficiency of butt joint construction of fixed connection is poor, and welding quality can not be guaranteed.
Therefore, a technical scheme for improving the working efficiency of the connecting and fixing device for the heated pipe pieces of the waste heat boiler in an opposite-opening manner and improving the welding construction quality is needed in the prior art.
SUMMERY OF THE UTILITY MODEL
Aiming at the defects of the prior art, the utility model provides a connecting and fixing device for a heated pipe piece and an external header of a waste heat boiler.
In order to achieve the purpose, the utility model is realized by the following technical scheme:
the utility model provides a be connected fixing device that is used for exhaust-heat boiler section of jurisdiction and external collection case that is heated, includes lock nut, bolt, section of jurisdiction and angle steel, the bolt runs through lock nut and with lock nut cooperatees, the section of jurisdiction includes first right-angle portion and second right-angle portion, the minor face of first right-angle portion with lock nut fixed connection, the long limit of first right-angle portion with the long limit fixed connection of second right-angle portion, the minor face orientation of second right-angle portion lock nut one side sets up, the angle steel pad is established the inside of second right-angle portion.
The number of the locking nuts, the number of the bolts and the number of the segments are two.
The two sides of the angle steel are equal in length.
Compared with the prior art, the utility model has the beneficial effects that: the locking nut is fixedly connected with the pipe piece, and tightly props against the pipeline through the screw, so that the accuracy of the butt joint of the heated pipe pieces of the waste heat boiler is improved, the pipe orifice butt joint construction efficiency is improved, and the welding quality is improved.
