[0015] The embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0016] In the related art, a passable transition bridge section usually refers to the end bridge section of a mechanized bridge, which is used as the transition part between the mechanized bridge and the construction area and is an important component of the mechanized bridge. Since the application environment of the mechanized bridge is relatively harsh, when the load of the bridge is too large, or the geological bearing capacity of the construction area contacting the end of the bridge is poor, such as the soil in the construction area is loose or relatively humid, the stability of the transition bridge section combined with the construction area is poor, which can easily cause the transition bridge section at the end of the bridge to have poor stability in the construction area, causing the bridge to become unstable and shake, and in severe cases, it may also cause accidents such as slope collapse in the construction area, which not only reduces the construction quality of the bridge, but also affects the transportation efficiency of vehicles, equipment and personnel, so that the practicality of the mechanized bridge is greatly reduced.

[0017] In view of this, the present application provides a passable transition bridge section of a mechanized bridge, including a bridge section body 100, a first telescopic rod 200, a second telescopic rod 300 and an auxiliary support component 400; a storage cabin 101 is provided at the bottom of the bridge section body 100, the first telescopic rod 200 and the second telescopic rod 300 are both rotatably connected to the inner wall of the storage cabin 101, and the piston rod of the first telescopic rod 200 is rotatably connected to the second telescopic rod 300 for adjusting the use angle of the second telescopic rod 300; the auxiliary support component 400 is connected to the piston rod of the second telescopic rod 300 for supporting the bridge section body 100.

[0018] like Figure 1-Figure 4As shown, the present application provides a mechanized bridge with a passable transition bridge section, which includes a bridge section body 100, a first telescopic rod 200, a second telescopic rod 300 and an auxiliary support component 400, which is used to provide auxiliary support to the bridge section body 100 to improve the stability of the transition bridge section erection; wherein the first telescopic rod 200 and the second telescopic rod 300 are both rotatably arranged on the inner wall of the storage cabin 101, and the piston rod of the first telescopic rod 200 is rotatably connected to the second telescopic rod 300. When erecting the mechanized bridge, it is necessary to place the bridge section body 100 in the construction area, and the construction area supports and bears the bridge section body 100; at this time, the piston rod of the first telescopic rod 200 is controlled to extend, driving the first telescopic rod 200 and The second telescopic rod 300 rotates in the storage cabin 101, and driven by the first telescopic rod 200, the deflection angle of the second telescopic rod 300 is changed until the second telescopic rod 300 is adapted to the slope of the construction area; at this time, the piston rod of the second telescopic rod 300 is controlled to extend so that the auxiliary support component 400 connected to the end of the piston rod of the second telescopic rod 300 abuts against the surface of the slope of the construction area, which is used to support the bridge section body 100, improve the erection quality and construction stability of the transition bridge section, and can also adapt to slopes with different inclination angles, avoid the collapse of the slope in the construction area and affect the normal use of the bridge, have good stability and safety, and ensure the transportation efficiency of vehicles, equipment and personnel.

[0019] Since a storage cabin 101 is provided at the bottom of the bridge section body 100, and the first telescopic rod 200 and the second telescopic rod 300 are both rotatably arranged on the inner wall of the storage cabin 101, when the mechanized bridge is folded, the piston rod of the first telescopic rod 200 and the piston rod of the second telescopic rod 300 can be controlled to be shortened respectively, and the second telescopic rod 300 and the auxiliary support component 400 are driven by the first telescopic rod 200 to enter the storage cabin 101, so as to realize the storage of the first telescopic rod 200, the second telescopic rod 300 and the auxiliary support component 400, thereby avoiding interference with the folding process of the bridge.

[0020] In some embodiments, the auxiliary support component 400 includes an articulated ball head 410, an articulated ball seat 420 and a support plate 430; the articulated ball head 410 is fixedly connected to the piston rod of the second telescopic rod 300, and the articulated ball seat 420 is provided with a movable groove 421 adapted to the articulated ball head 410, and the articulated ball head 410 is rotatably arranged in the movable groove 421; the support plate 430 is fixedly connected to the articulated ball seat 420.

[0021] like Figure 1-Figure 3As shown, due to the different application environments of the transition bridge section, the inclination angles of the slopes in different construction areas are also different. By setting an auxiliary support component 400 at the piston rod end of the second telescopic rod 300, the support capacity of the overlapping area for the transition bridge section can be improved; wherein, the auxiliary support component 400 includes an articulated ball head 410, an articulated ball seat 420 and a support plate 430, and the articulated ball head 410 is set in the accommodating cavity of the articulated ball seat 420 and is adapted thereto, so that the articulated ball head 410 can rotate relative to the articulated ball seat 420; The piston rod end of the second telescopic rod 300 is fixedly connected, and the articulated ball seat 420 is fixedly connected to the support plate 430. Therefore, the support plate 430 can fully abut against the slope surface at different inclination angles under the push of the second telescopic rod 300, so that the transition bridge section has good stability when erected in the construction area; in addition, the second telescopic rod 300 can apply uniform pressure to the slope of the overlap area through the support plate 430, and can squeeze the slope to prevent the bridge from being overloaded and causing the slope to collapse, so as to ensure the support effect of the construction area on the transition bridge.

[0022] Since the first telescopic rod 200 and the second telescopic rod 300 are both rotatably connected to the inner wall of the storage cabin 101, when the mechanized bridge is folded, it is necessary to first store the first telescopic rod 200, the second telescopic rod 300 and the auxiliary components into the storage cabin 101. Since the second telescopic rod 300 and the support plate 430 are connected via the articulated ball head 410 and the articulated ball seat 420, the angle between the second telescopic rod 300 and the support plate 430 can be adjusted so that the two are close to each other and folded, so that the auxiliary support component 400 can be stored into the storage cabin 101 to avoid interference with the folding process of the bridge.

[0023] In some embodiments, a plurality of anti-slip protrusions (not marked in the figure) are evenly arranged on one side of the support plate 430 away from the hinge ball seat 420; Figure 3 As shown, multiple anti-slip protrusions can be evenly arranged on the side of the support plate 430 away from the articulated ball seat 420 and the side of the support plate 430 close to the slope of the construction area, so as to increase the friction between the support plate 430 and the slope, avoid the auxiliary support component 400 from slipping or falling off during the support process, and ensure the stability of the transition bridge section when in use.

[0024] In some embodiments, a hatch 500 is slidably provided at the bottom of the bridge section body 100, and the area of ​​the hatch 500 is greater than or equal to the opening area of ​​the storage compartment 101; Figure 1 and Figure 2As shown, since the first telescopic rod 200 and the second telescopic rod 300 are both arranged in the storage cabin 101, when the mechanized bridge is recovered, in order to prevent the first telescopic rod 200, the second telescopic rod 300 and the auxiliary support component 400 from affecting the folding action of the bridge, the three need to be stored in the storage cabin 101; at this time, by setting a hatch 500 at the bottom of the bridge section body 100, and making the hatch 500 and the bridge section body 100 slidingly connected, when the hatch 500 is closed, the storage cabin 101 can be closed to prevent the first telescopic rod 200, the second telescopic rod 300 and the auxiliary support component 400 from leaking out and interfering with the normal folding of the bridge, avoiding bumps during the folding process; and the area of ​​the hatch 500 is larger than the opening area of ​​the storage cabin 101, so that the hatch 500 can fully cover the storage cabin 101.

[0025] It should be noted that sliding rails can be set on both sides of the above-mentioned middle cabin door 500, and sliding grooves compatible with the sliding rails can be set on the bridge section body 100, so that the cabin door 500 can slide on the bridge section body 100 through the sliding rails and the sliding grooves, so as to facilitate the blocking of the opening of the storage cabin 101, which will not be elaborated here.

[0026] In some embodiments, the transition bridge section also includes a gripping structure 600; a accommodating cabin 102 is provided at the bottom of the bridge section body 100, and the gripping structure 600 is arranged inside the accommodating cabin 102; wherein, the gripping structure 600 includes a rotating shaft 610, a clamping block 620 and a third telescopic rod 630; the clamping block 620 is rotatably connected to the bridge section body 100 via the rotating shaft 610; a clamping protrusion 621 is provided on the clamping block 620; the third telescopic rod 630 is rotatably connected to the inner wall of the accommodating cabin 102, and the end of its piston rod is rotatably connected to the clamping block 620; the accommodating cabin 102 includes a first accommodating chamber 102a and a second accommodating chamber 102b which are interconnected; the clamping block 620 is slidably arranged in the first accommodating chamber 102a, and the third telescopic rod 630 is located in the second accommodating chamber 102b.

[0027] like Figure 1 and Figure 4As shown, the transition bridge section also includes a gripping structure 600 for improving the firmness of the transition bridge section in the construction area; wherein the gripping structure 600 includes a rotating shaft 610, a clamping block 620 and a third telescopic rod 630, the clamping block 620 can be rotatably connected to the bridge section body 100 through the rotating shaft 610, the accommodating chamber 102 includes a first accommodating chamber 102a for accommodating the clamping block 620, and a second accommodating chamber 102b for accommodating the second clamping block 620, the clamping block 620 is slidably arranged in the first accommodating chamber 102a, the third telescopic rod 630 is rotatably connected to the inner wall of the second accommodating chamber 102b, and its piston rod output end is rotatably connected to the clamping block 620; when the third telescopic rod 630 When the piston rod is extended, it can drive the clamping block 620 connected thereto to rotate along the rotating shaft 610 and slide along the first accommodating chamber 102a, so that the clamping block 620 extends from the first accommodating chamber 102a to form a protruding structure at the bottom of the bridge section body 100. When the transition bridge section is placed in the construction area, the engaging protrusion 621 of the clamping block 620 can be embedded in the surface of the construction area, thereby improving the firmness and stability of the transition bridge section in the construction area. Similarly, when the piston rod of the third telescopic rod 630 is shortened, it can drive the clamping block 620 to rotate in the opposite direction along the rotating shaft 610, so that the clamping block 620 returns to the first accommodating chamber 102a, thereby avoiding interference with the bridge during the folding process.

[0028] In some embodiments, a guide block 700 is provided on the side of the clamping block 620 away from the rotating shaft 610, and the guide block 700 is slidably set on the inner wall of the first accommodating cavity 102a; the inner wall of the first accommodating cavity 102a is set as an arc-shaped surface; the inner wall of the first accommodating cavity 102a is provided with a limit block 800 for limiting the clamping block 620, and the limit block 800 is slidably set on the surface of the clamping block 620.

[0029] like Figure 1 and Figure 4As shown, by providing a gripping structure 600 on the bridge section body 100, the stability of the transition bridge section in the construction area can be improved; wherein, since the clamping block 620 is rotatably connected to the bridge section body 100 through the rotating shaft 610, by providing an arc surface on the side of the first accommodating cavity 102a away from the rotating shaft 610, and making the guide block 700 fixedly connected to the surface of the clamping block 620 slide on the arc surface of the first accommodating cavity 102a, the movement trajectory of the clamping block 620 can be further restricted, ensuring that the clamping block 620 can move along the first The accommodating cavity 102a can be smoothly extended or retracted, and at the same time, it can also ensure that the locking protrusion 621 of the locking block 620 can be embedded in the ground after extending from the first accommodating cavity 102a, thereby playing a role in stabilizing the transition bridge section; in addition, by setting a limit block 800 on the inner wall of the first accommodating groove and making the limit block 800 slide on the surface of the locking block 620, the movement trajectory of the locking block 620 can be restricted, and the locking block 620 can be prevented from detaching from the first accommodating cavity 102a, thereby ensuring that the locking block 620 can be smoothly extended and retracted.
