Embodiment Construction

[0013] The present invention will be further described below in conjunction with accompanying drawing.

[0014] Such as figure 1 As shown, a mobile bridge quick-insert pin device is composed of two parts: a pin mechanism and a power mechanism. The latch mechanism is made up of latch seat 1, long pin 2, shaft seat 3, gear shaft 4, and short pin 5. The pin seat 1 and the shaft seat 3 are installed at the end of the bridge joint 6, the long pin 2 is installed in the pin seat 1, the short pin 5 is installed in the pin seat 1', the threaded part of the tail of the long pin 2 and the short pin 5 is connected with the gear The threaded hole of the shaft 4 fits; the gear shaft 4 is installed in the shaft seat 3 and the shaft seat 3'.

[0015] Such as figure 2 As shown, the cross-section of the head 21 of the long pin 2 is circular, the cross-section of the middle part 22 is square, the middle and rear part 23 is a circular shaft, and the tail part 24 is a threaded structure. The ...

Abstract

A fast pin inserting and extracting device is composed of a pin inserting mechanism and a power mechanism. The pin inserting mechanism is composed of an inserting pin seat, a long pin, a shaft seat, a gear shaft and a short pin. The power mechanism comprises a pin tooth ring, a shaft and the like and is arranged on an erected platform. Power is provided for the pin inserting mechanism through the power mechanism to drive the pin inserting mechanism at the end portion of a bridge section to actuate, pin insertion and extraction are performed, and connection and disconnection of bridge spans are achieved. The fast pin inserting and extracting mechanism is utilized to perform connection and disconnection between the bridge joints, personnel remote operation or operation in a safe area can be achieved, erection difficulties are reduced, and danger of erection personnel is reduced.

Description

technical field [0001] The invention relates to a quick plug-in and pull-out pin mechanism between bridge sections of a movable bridge. Background technique [0002] The existing mobile bridge is composed of two or more bridge sections. During the erection process, the bridge sections need to be connected to form a pair of bridge spans. When the bridge sections are connected, the erector manually inserts the pins, or uses hydraulic cylinders inside the bridge. Carry out bolt connection (need to manually connect the erection platform to the hydraulic pipeline in the bridge). The disadvantages of manual bolting and bolting with hydraulic oil cylinders in the bridge are that the erectors need to perform manual operations, which increases the labor intensity of the erectors, and is not suitable for dangerous emergency rescue sites. Contents of the invention [0003] The invention proposes a mobile bridge fast plug-in and pull-out device, which uses the power provided by the e...
