Embodiment 1

[0024] A tray connecting device, comprising a fastener arranged above the tray 6, and also includes a clamping plate 4 arranged below the tray 6, the clamping plate 4 is provided with a groove, and the groove is attached to the fastener Screw holes are provided on the lower surface of the clamping plate 4 corresponding to the fasteners, and the fasteners are fixed on the tray 6 through the bolts 1 passing through the screw holes and the nuts 2 .

Embodiment 2

[0026] A tray connecting device, similar to Embodiment 1, the difference is that a washer 3 is provided between the fastener and the nut 2; the fastener adopts a support ring 5; the side of the clamping plate 4 is set as L-shaped; the L-shaped bending part of the clamping plate 4 is provided with a round chamfer; the end surface of the groove is set as U-shaped; the bolt 1 is a headed bolt.

Embodiment 3

[0028] A tray connecting device is similar to Embodiment 1, except that it is equipped with a screwdriver; the screwdriver matches the type of the bolt 1; the number of the grooves is two.

[0029] A kind of tray connecting device of the present invention, it opens a hole on the tray 6, sticks on the lower surface of the support ring 5 with two grooves on the clamping plate 4, fastens the fastener with the nut 2 on the tray 6 Fixed on the tray 6, increasing the force of the bolt 1, the support ring 5 and the clamping plate 4 will be deformed at the contact position, which improves the fastening reliability. Remove the tray 6 from above, loosen the nut 2 above the washer 3, insert a screwdriver into the notch of the bolt 1, and rotate 90° to remove the tray 6 from above.

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.

Description

technical field [0001] The invention belongs to the technical field of fixed connection, and relates to a fixed connection device for a tray, in particular to a tray connection device used for connecting trays, support rings and support beams of plate towers in oil refining and chemical industries. Background technique [0002] At present, with the rapid development of my country's economy, the demand for refined oil is strong, and the long-term high-load production of the oil refining industry has increased the gas and liquid phase loads of the fractionation tower, even exceeding the design load, and the reliability requirements for the tray fasteners have increased; from According to the operation of fractionation towers in refining and chemical plants, some towers have blown up trays due to insufficient fastening force of fasteners, which affects the fractionation precision. The clips used for the trays in the prior art have insufficient clamping performance in structure, ...
