Problems solved by technology

[0003] For example, a telescopic emergency bridge proposed by the application number CN201710346249.1, the emergency bridge constitutes the main body of the bridge through two sets of upper and lower support plates, and the upper and lower support plates are connected by a movable support frame, and a single upper and lower set of support plates They can be firmly connected, but because the upper support plate and the lower support plate are designed in sections, bolts are used in the sections, and because the bolts are most affected by the load, only using bolts to connect will bring the disadvantage of insufficient strength , if the subsection bears a large load, there is a certain potential safety hazard; and the above invention cannot adjust the height of the emergency bridge in time according to the flood danger, which will cause the emergency bridge to be submerged due to the rising flood and affect the passage of emergency personnel, thereby reducing the rescue efficiency of emergency personnel

Embodiment 1

[0028] like Figure 1 to Figure 9 As shown, the present invention provides a movable emergency bridge device for road bridges, comprising a bottom support frame 1, a fixing member 2 is arranged at the right end of the bottom support frame 1, a beam 3 is installed on the fixing member 2, and the bottom of the inner side of the beam 3 is provided with a fixing member 2. A limit card 4 and a pulley block 6 are slidably connected to the top of the pulley block 6 with a sliding frame 5 , a plurality of extension frames 8 are connected in series on the right end of the sliding frame 5 , and a cable frame 7 is fixedly installed on the top of the beam 3 .

[0029] The limit clip 4 is hinged with the inner side of the beam 3, and the limit clip 4 is provided with a hole through which the bolt passes, and the inner side of the beam 3 is fixed with a nut matched with the bolt. By passing the bolt through the hole on the limit clip 4 and The fixing of the limit card plate 4 can be complet...

Embodiment 2

[0044] As a further improvement of the above technical solution, when an emergency situation occurs and the emergency bridge needs to be quickly retracted, the emergency bridge can be retracted quickly in the following manner.

[0045] When the emergency bridge needs to be retracted quickly, first control the retraction of the second electromagnetic latch 84 on the first extension frame 8 on the side of the sliding frame 5 to unlock the sliding frame 5 and the first extension frame 8, and then control the first extension frame 8 by controlling the first extension frame 8. The first electric telescopic rod 72 under the sling 16 corresponding to one extension frame 8 is extended. Since the sliding frame 5 is unlocked from the first extension frame 8, the first extension frame 8 can rotate relative to the sliding frame 5, and the first extension frame 8 can rotate relative to the sliding frame 5. The electric telescopic rod 72 is extended, so that the first extension frame 8 is ro...

Embodiment 3

[0048] As a further improvement of the above technical solution, when the flood rises, because the emergency bridge is submerged by the flood, rescuers and trapped persons cannot directly observe the position of the emergency bridge with the naked eye, but can only touch and test the position of the emergency bridge by footsteps. The passing speed of the rescuers and the trapped persons is to ensure that even if the emergency bridge encounters a rising flood, the passing speed of the rescuers and the trapped persons is not affected, and the rescue is carried out according to the method described in this embodiment.

[0049] When the flood rises, the second electromagnetic latch 84 on the first extension frame 8 can be controlled to shrink, and at the same time, the first electric telescopic rod 72 under the sling 16 corresponding to the first extension frame 8 can be controlled to extend, Rotate the first extension frame 8 upwards, when it rotates up to a suitable height, stop ...

Abstract

The invention belongs to the technical field of emergency bridges, and discloses a movable emergency bridge device for road bridges. The bottom of the inner side of the beam is provided with a limit card plate and a pulley group, the top of the pulley group is slidably connected with a sliding frame, the right end of the sliding frame is connected in series with a plurality of extension frames, and the top of the beam is fixedly installed with a cable frame; The mutual cooperation between the extension frame, the sliding frame, the sling, the first electric telescopic rod, etc., by controlling the contraction and extension of the second electromagnetic bolt, and at the same time, by controlling the contraction or extension of the first electric telescopic rod, the emergency bridge is transformed into a Arch emergency bridge, so that the bridge body is raised to avoid affecting the rescue of rescuers due to the rising flood.

Description

technical field [0001] The invention belongs to the technical field of emergency bridges, in particular to a movable emergency bridge device for road bridges. Background technique [0002] The emergency bridge is a kind of emergency equipment, which belongs to a temporary bridge used in emergency rescue and disaster relief. It can temporarily replace the destroyed bridge and is used by rescue personnel to perform disaster relief tasks. Important disaster relief equipment. [0003] For example, a telescopic emergency bridge proposed by application number CN201710346249.1, the emergency bridge consists of upper and lower two groups of support plates to form the main body of the bridge, and the upper and lower support plates are connected by a movable support frame, a single upper and lower two groups of support plates They can be firmly connected, but because the upper support plate and the lower support plate are designed in sections, bolts are used at the sections. Since th...
