Problems solved by technology

[0003] The horizontal connection between the existing pontoon bridge units, one is to complete the pre-connection on the shore before the pontoon bridge unit is unloaded into the water, and the other is to complete the connection underwater in the form of a third hook; when the pontoon bridge unit is horizontally connected on land, the total When the weight exceeds the upper limit of the carrier, the former cannot be realized; while the Bingding hook in the latter needs to lift or press down the two pontoon bridge units that need to be connected to each other, so that the height difference exceeds the thickness of the Bingding hook and then buckle in place. , this connection method is inconvenient to observe underwater, which makes the connection difficult, and the connected Bingding hook can only resist tension, and does not have the functions of compressive resistance and shear resistance

Embodiment Construction

[0026] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0027] This embodiment provides a horizontal connection device at the lower part of the pontoon bridge, which can be quickly connected and has the functions of tensile resistance, compression resistance and shear resistance.

[0028] Such as Figure 1-3 As shown, the horizontal connection device includes: the lower transverse plate pin 1 and the lower transverse plate pin seat 2; wherein, the lower transverse plate pin 1 includes: the base 3, the transmission fork 4, the pin shaft 5, the flange cover 6, and the transmission shaft 7 , single lug seat 8 and connecting plate 9; Bottom transverse plate pin seat 2 comprises: crowbar cover 10, bolt pin 11, bracket 12, bearing pin 14, pull bar 15, vertical pin 16 and double lug seat 17.

[0029] The connection relationship of the horizontal connecting device is: the lower transverse plate pin 1 and the lower tra...

Abstract

The invention discloses a pontoon bridge lower transverse connecting device. The pontoon bridge lower transverse connecting device comprises a lower transverse plate pin and a lower transverse plate pin seat. The lower transverse plate pin and the lower transverse plate pin seat are arranged on two adjacent pontoon bridge units; and the lower transverse plate pin can rotate in a horizontal plane,is inserted into the lower transverse plate pin seat after rotating by a set angle to achieve transverse connection between lower portions of two pontoon bridge units, and is screwed out of the lowertransverse plate pin seat after rotating by a set angle reversely to achieve unlocking of the two pontoon bridge units.

Description

technical field [0001] The invention relates to the technical field of horizontal connection at the lower part of a pontoon bridge, in particular to a horizontal connection device at the lower part of a pontoon bridge. Background technique [0002] The lower horizontal connection of the pontoon bridge (hereinafter referred to as the horizontal connection) is more difficult than the connection on the water (such as the deck connection) because the connector is underwater during use. [0003] The horizontal connection between the existing pontoon bridge units, one is to complete the pre-connection on the shore before the pontoon bridge unit is unloaded into the water, and the other is to complete the connection underwater in the form of a third hook; when the pontoon bridge unit is horizontally connected on land, the total When the weight exceeds the upper limit of the carrier, the former cannot be realized; while the Bingding hook in the latter needs to lift or press down the...
