In addition, the terms "first", "second", "third" and the like are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0019] Example

[0020] Combination Figure 1-3As shown, an adjustable ladder-type cable bridge includes a bridge body, the bridge body includes two symmetrically arranged baffles 1, a plurality of equally spaced bearing plates 2 are arranged between the two baffles 1, the bearing plates 2 and the baffles 1 are connected by welding, thereby improving the connection strength and service life of the two, and the overall strength and bearing strength of the bridge body are improved by the matching arrangement of the baffles 1 and the bearing plates 2, a fixing block 201 integrally formed with the bearing plate 2 is provided on the top of the bearing plate 2, connecting columns 202 are symmetrically provided on both sides of the fixing block 201, a plurality of evenly distributed first connecting holes 203 for fastening bolts 4 to be inserted are opened through the connecting column 202, and a side plate 3 extending along the length direction of the baffle 1 is provided on the outer side of the connecting column 202.

[0021] like Figure 3 The side panel 3 shown in the figure has a plurality of equally spaced docking posts 301 on the inner side thereof, a connecting groove 302 for plugging the connecting post 202 is provided at one end of the docking post 301 away from the side panel 3, a second connecting hole 303 connected to the first connecting hole 203 is provided through the top of the docking post 301, the second connecting hole 303 is connected to the connecting groove 302, the second connecting hole 303 and the first connecting hole 203 are internal threaded holes of the same structural size, and the second connecting hole 303 is a countersunk hole, so as not to affect the laying of cables in the bridge body, and the first connecting hole 203 and the second connecting hole 303 are provided in conjunction with the fastening bolts 4, so as to improve the connection strength of the bridge body after adjusting the width.

[0022] Among them, a plurality of evenly distributed guide blocks 304 are provided at the bottom of the side panel 3, and guide grooves 204 capable of allowing the guide blocks 304 to move forward and backward are symmetrically opened on the top end surfaces of the bearing plates 2 on both sides of the fixed block 201. The guide grooves 204 and the guide blocks 304 are matched with each other, thereby improving the stability of the displacement of the side panel 3 when adjusting the width of the bridge frame body.

[0023] The working principle of the utility model is:

[0024] When the width of the bridge frame body needs to be adjusted, the fastening bolts 4 are loosened one by one and pulled out from the first connecting hole 203 and the second connecting hole 303, and then one of the side panels 3 or the two side panels 3 is moved toward the baffle 1. When the side panel 3 moves, the guide block 304 at the bottom of the side panel 3 is displaced in the guide groove 204 on the bearing plate 2, thereby improving the stability of the side panel 3 during displacement. At the same time, the connecting column 202 slides and displaces in the connecting groove 302. After the displacement adjustment is completed, the fastening bolts 4 are inserted into the connected first connecting hole 203 and the second connecting hole 303, and the connecting column 202 is fixedly connected to the docking column 301, thereby completing the width adjustment of the bridge frame body.
