Abstract
The invention relates to a column tray connecting device. The column tray connecting device comprises a fastener on a column tray, and also comprises a clamp plate below the column tray. The clamp plate is provided with grooves. The grooves cling to the lower surface of the fastener. A position on the clamp plate, which is corresponding to the fastener, is provided with a screw hole. The fastener is fixed to the column tray by passing a bolt through the screw hole and by a nut. The groove surfaces of the clamp plate of the column tray are aligned with a supporting ring, thus reducing the area of thrust surface of the supporting ring, enhancing self-fastening performance by utilization of local deformation during loading, and increasing positioning reliability. The column tray connecting device has advantages of a reasonable clamping structure, a compact structure, good fastening force performance, firm connection, capability of enhancing column tray fastening stability under high load conditions, and capability of guaranteeing high-load production of equipment. The column tray connecting device is suitable for connection between a column tray and a column tray supporting ring for a plate column in the oil refining industry and the chemical industry, high in positioning precision, high in fastening reliability, and suitable for high-load production of equipment, and can meet requirements of practical situations.

In above scheme preferably, packing ring is provided with between described securing member and nut.
Can also preferably, described securing member adopts bracing ring.
Can also preferably, the side of described clamp is set to L shape.
Can also preferably, the bending place of the L shape of described clamp is provided with rounded corner.
Can also preferably, the end face of described groove is set to U-shaped.
Can also preferably, described bolt adopts tap bolt.
Can also preferably, described tray attachment apparatus is also equipped with screwdriver.
Can also preferably, described screwdriver matches with the model of bolt.
Can also preferably, the quantity of described groove is two.
Tray attachment apparatus of the present invention, in use, first perforate on tower tray, then be attached on securing member lower surface with the groove on clamp, at tray thereabove nut, securing member be fixed on tower tray, increase bolt force, securing member and clamp can deform in contact site, improve fastening reliability; Tear tower tray open from above, unscrew the nut of washer, with screwdriver inserting bolt notch, half-twist can take off tower tray from above.
Tray attachment apparatus of the present invention, its groove face at tower tray clamp aims at bracing ring, reduces bracing ring lifting surface area, utilizes local deformation when loading to improve self-tightening performance, improves reliability of positioning; Have clamp structure reasonable, compact conformation, fastening force performance is good, is connected firmly, and improves the tower tray fastening reliability under high-load condition, and the advantage of the production at high load of ensuring equipment; Gripping performance existing in prior art can be solved not enough, fastening force is less than normal, problems such as loosening, come off is easy under causing high liquid phase load, the shortcoming come off is easy under overcoming common connector high load capacity, be applicable to refine oil, the connection of chemical industry plate column tower tray and tower tray bracing ring, positioning precision is high, and fastening reliability is high, be suitable for the production at high load of device, the needs of actual conditions can be met.
