Description
TECHNICAL FIELD
[0001] The utility model relates to vertical shaft derrick construction technical field, concretely to a kind of vertical shaft derrick inclined rack air butt joint temporary fixing device. BACKGROUND
[0002] When building the top pulley platform of vertical shaft derrick, if the platform volume is too large, it needs to be layered and then welded as a whole. In order to improve the stress strength, the top pulley platform is generally a conical structure. Therefore, the installation of inclined rack is an important link when the top pulley platform is butt jointed. The air butt joint construction of inclined rack cannot complete the air welding work on the same day, so a hinge fixing device is used for temporary fixing to replace the box body weld joint for connection and positioning. The commonly used temporary fixing hinge structure is relatively simple and is directly welded on the outside of the upper and lower inclined rack splicing surface. When the upper and lower inclined racks are spliced, the lower inclined rack is fixed and the upper inclined rack is lifted by a crane. Then, the upper inclined rack is slowly moved above the lower inclined rack and the upper and lower hinge structures are inserted. Finally, a pin is inserted into the position where the upper and lower hinge structures are inserted. However, the above method has many problems. On the one hand, the upper and lower hinge structures protrude from the lower end of the upper inclined rack and the upper end of the lower inclined rack. Since the inclined rack has a large mass, if the protruding end surface part of the hinge structure collides during transportation or lifting, it is easy to deform and cannot be used normally and is difficult to repair. On the other hand, the butt joint of the upper and lower hinge structures relies on the slow adjustment of the lifting machine and needs to be very accurate in position to be connected together, which is not easy to operate.

[0024] When using, first make a batch of hinged seat assembly 3 with the same structure size, then give each head pulley upper inclined frame 1 lower end and head pulley lower inclined frame 2 upper end a threaded hole through the through hole on the bottom plate 301, so that the hinged seat assembly 3 can be fixedly connected with it through bolts, when the head pulley platform is transported from the factory to the construction site, first disassemble the hinged seat assembly 3, because the hinged seat assembly 3 has been disassembled when the head pulley platform is transported, so it will not be damaged during transportation due to the extrusion of the head pulley platform, after the head pulley platform is transported to the site, first fix the lower part to the ground, then fix the hinged seat assembly 3 above the head pulley lower inclined frame 2 of the lower part of the head pulley platform through screws, further hoist the upper part of the head pulley platform slightly away from the ground, then fix the hinged seat assembly 3 below the head pulley upper inclined frame 1 of the upper part of the head pulley platform through screws, further hoist the upper part of the head pulley platform high and align it with the lower part of the head pulley platform according to the angle in advance, that is, the connecting ends of the upper and lower inclined frames are aligned up and down and the distance should not be too large, about half a meter, in this process, the hinge 4 is not installed on the inclined frame and the hinged seat assembly 3 does not protrude from the end face, so it is not easy to be damaged when the upper head pulley platform is hoisted and aligned, even if you are very unlucky and accidentally hit the already installed hinged seat assembly 3, you only need to disassemble it through bolts to replace a new one, further, workers can install the hinge 4 according to their own actual situation, that is, they can choose to fix the upper connecting rod 401 to the hinged seat assembly 3 on the side of the head pulley upper inclined frame 1 first, then connect the lower connecting rod 402 to the steel wire rope 7 and pull it to the hinged seat assembly 3 of the head pulley lower inclined frame 2, or they can fix the lower connecting rod 402 first and then the upper connecting rod 401, when one of the connecting rods of the hinge 4 has been fixed to the hinged seat assembly 3, then pass the steel wire rope 7 connected to the other connecting rod through the wire hole 306, then the worker can guide the connecting rod into the groove between the side plates 302 by tightening the steel wire rope 7, the specific operation is to slowly lower the upper part of the head pulley platform by the crane, then the worker pulls the connecting rod into the auxiliary bridge 304 through the steel wire rope 7, then as the upper part of the head pulley platform continues to descend, the worker continues to pull the connecting rod into the groove between the side plates 302 through the steel wire rope 7, when the distance between the upper part of the head pulley platform and the lower part of the head pulley platform is only a few centimeters, the connecting rod has also been inserted obliquely into the groove between the side plates 302, further tighten the compression bolt 6 downward and press it onto the upper surface of the connecting rod, then continue to slowly lower the upper part of the head pulley platform by the crane, and the worker continues to tighten the compression bolt 6 downward, in this process, even if the crane does not accurately hoist the upper part of the head pulley platform directly above the lower part of the head pulley platform, but when the upper and lower head pulley platforms are connected, the position will be forcibly corrected by the connecting rod inserted into the hinged seat assembly 3, so that the upper and lower inclined frames can be easily connected.
[0025] In summary, the temporary fixing device for the overhanging butt joint of the shaft head inclined frame divides the hinged structure into three parts, two hinged seat assemblies 3 and one hinge 4. The hinged seat assemblies 3 are not installed on the inclined frame before splicing, so that the collision during transportation can be avoided. When splicing, the hinged seat assemblies 3 have been installed on the inclined frame, but they do not protrude from the end surface of the inclined frame, so that they will not be deformed by collision during lifting. Only when the two hinged seat assemblies 3 are basically aligned, the inclined frame is connected through the hinge 4, so that the effect of collision and deformation of the hinged structure can be achieved. When the hinged seat assemblies 3 installed on the upper and lower end of the inclined frame are basically aligned, one of the connecting rods is fixed with one hinged seat assembly 3, and then the other connecting rod is pulled into the groove of the other hinged seat assembly 3 through the steel wire rope 7. The auxiliary bridge 304 can assist the connecting rod to enter between the side plates 302. The connecting rod can be pressed into the side plates 302 by screwing down the pressing bolt 6. Compared with directly relying on the positioning of the crane, this method is more detailed and faster.
[0026] The above is only the preferred embodiment of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
