Description

Technical Field

[0001] This utility model relates to the field of transportation and emergency rescue machinery and equipment, specifically to an angle-adjustable mobile truss bridge. Background Technology

[0002] In recent years, natural disasters such as earthquakes and severe weather have occurred frequently, and floods caused by global warming have become increasingly frequent, posing a huge threat to the lives and property of residents along the coast. In order to reduce the harm caused by floods, it is necessary to establish stable, reliable, and widely adaptable passageways for evacuation.

[0003] The current primary method is to establish a stable, safe, and efficient passageway by connecting rescue boats to the shore. Traditional boat-based passage bridges often employ fixed-joint or telescopic extension methods. Fixed-joint bridges are erected mainly through manual labor or machine hoisting, extending gradually from short to long, which is labor-intensive and time-consuming. Telescopic extension bridges, using mechanical methods to push the bridge out, are limited by the cantilever structure, resulting in significant deformation at the bridge's ends and large bending moments at the fixed cantilever end during extension, making long-distance extension difficult. Furthermore, the pitch and angle of the rescue bridge are difficult to adjust, hindering its adaptation to changes in water level and terrain. Utility Model Content

Detailed Implementation

[0030] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered by the claims.

[0031] See Figures 1 to 2 The angle-adjustable movable truss bridge includes a bridge body 1, a linear moving device 3, and a lifting device 4. The first end of the bridge body 1 is slidably hinged to the hull 8 along a first direction, and the second end of the bridge body 1 is used to connect with the shore foundation 9. The linear moving device 3 includes two moving mechanisms 3.1 arranged opposite to each other on the hull 8, and the output end of the moving mechanism 3.1 is connected to the bridge body 1. One moving mechanism 3.1 drives the bridge body 1 to move along the first direction, and the other moving mechanism 3.1 drives the bridge body 1 to move in the opposite direction of the first direction. The lifting device 4 is vertically arranged on the hull 8, and the output end of the lifting device 4 is in rolling contact with the second end of the bridge body 1. The lifting device 4 can lift or lower the second end of the bridge body 1. In this embodiment, two moving mechanisms 3.1 can drive the bridge body 1 to move in the first direction or the opposite direction, thereby extending or retracting the bridge body 1 onto the hull 8 in the first direction to adapt to the longer shoreline 9 in shallow water areas. The lifting device 4 can lift or lower the second end of the bridge body 1, while the guiding mechanism 4.3 rolls along the bridge body 1, and the bridge body 1 rotates relative to the hull 8, facilitating the adjustment of the bridge body 1's angle to adapt to different terrains and water levels, thus enabling the bridge body 1 to connect with shorelines 9 at different distances and heights. Furthermore, when the bridge body 1 is not in operation, it retracts onto the hull 8, effectively reducing the total length of the hull 8, minimizing the space occupied during storage, and optimizing the spatial layout of the hull 8.

[0032] Based on the above embodiments, the moving mechanism 3.1 includes a moving drive component 3.1.1, a steering component 3.1.2, a first anchor box 2.3.3, and a traction rope 3.1.4. The moving drive component 3.1.1 and the steering component 3.1.2 are both mounted on the hull 8. The first anchor box 2.3.3 is mounted on the bridge body 1 along a first direction. The first end of the traction rope 3.1.4 is connected to the output shaft of the moving drive component 3.1.1, and the second end is connected to the first anchor box 2.3.3 via the steering component 3.1.2. When the bridge body 1 extends beyond the hull 8, the moving mechanism 3.1, away from the shore base 9, retracts the traction rope 3.1.4 to pull the bridge body 1 along the first direction to approach the shore base 9, and pulls out the traction rope 3.1.4 in the moving mechanism 3.1 that is close to the shore base 9 to facilitate the extension of the bridge body 1; when the bridge body 1 retracts beyond the hull 8, the moving mechanism 3.1, close to the shore base 9, retracts the traction rope 3.1.4 to pull the bridge body 1 along the first direction to approach the shore base 9, and pulls out the traction rope 3.1.4 in the moving mechanism 3.1, away from the shore base 9 to facilitate the retraction of the bridge body 1. The moving drive component 3.1.1 is an electric winch or a hydraulic winch, and the steering component 3.1.2 can turn the traction rope 3.1.4 so that the traction rope 3.1.4 can pull the bridge body 1 back and forth along the first direction.

[0033] The steering assembly 3.1.2 includes a base 3.1.2.1 and a first steering wheel 3.1.2.2 and a second steering wheel 3.1.2.3 vertically mounted on the base 3.1.2.1. The first steering wheel 3.1.2.2 is flush with the first anchor box 2.3.3; the second steering wheel 3.1.2.3 is flush with the output shaft of the moving drive component 3.1.1. A traction rope 3.1.4 is led out from the moving mechanism 3.1, passes through the second steering wheel 3.1.2.3 and the first steering wheel 3.1.2.2, and connects to the first anchor box 2.3.3. The traction rope 3.1.4 passes through the first steering wheel 3.1.2.2 and the second steering wheel 3.1.2.3 and connects to the first anchor box 2.3.3 to overcome the installation distance between the moving drive component 3.1.1 and the bridge body 1, and converts the traction force at the installation height of the moving drive component 3.1.1 into the traction force at the height of the bridge body 1, so as to facilitate the traction of the bridge body 1.

[0034] Furthermore, such as Figure 6 and Figure 7As shown, the lifting device 4 includes a mounting sleeve 4.1, a lifting drive component 4.2, and a guide mechanism 4.3. The mounting sleeve 4.1 is vertically mounted on the hull 8. The lifting drive component 4.2 is disposed within the mounting sleeve 4.1 and is hinged to the mounting sleeve 4.1. One end of the guide mechanism 4.3 is in rolling contact with the bridge body 1, and the other end of the guide mechanism 4.3 extends into the mounting sleeve 4.1 and is hinged to the output shaft of the lifting drive component 4.2. The output shaft of the lifting drive component 4.2 is in rolling contact with the bridge body 1 through the guide mechanism 4.3, thus both lifting the bridge body 1 and accommodating its rotation. The mounting sleeve 4.1 limits the guide mechanism 4.3, restricting the hinge angle between the guide mechanism 4.3 and the lifting drive component 4.2, thereby ensuring rolling contact between the guide mechanism 4.3 and the bridge body 1. The mounting sleeve 4.1 also protects the lifting drive component 4.2. The lifting drive component 4.2 is hinged to the mounting sleeve 4.1, which is beneficial to the force on the lifting drive component 4.2. When the bridge body 1 is lifted, the lifting drive component 4.2 can rotate at a certain angle, thereby reducing the rotation of the guide seat 4.3.1 and ensuring the rolling contact between the guide seat 4.3.1 and the bridge body 1. The lifting drive component 4.2 is a hydraulic cylinder, but it can also be implemented using other transmission forms such as gear rack, lead screw nut, crank slider and cam mechanism.

[0035] The guiding mechanism 4.3 includes a guide seat 4.3.1, a mounting platform 4.3.2, and bottom guide wheels 4.3.3 and side guide wheels 4.3.4 mounted on the mounting platform 4.3.2. Part of the guide seat 4.3.1 extends into the mounting sleeve 4.1 and is hinged to the output shaft of the lifting drive component 4.2, and the side wall of the guide seat 4.3.1 is arc-shaped. The mounting platform 4.3.2 is mounted on the guide seat 4.3.1, and the bottom guide wheel 4.3.3 makes rolling contact with the bottom wall of the bridge body 1. The number of side guide wheels 4.3.4 is at least two, and the two side guide wheels 4.3.4 make rolling contact with the two side walls of the bridge body 1 in the width direction. The guide mechanism 4.3 makes rolling contact with the bottom wall and two side walls of the bridge body 1 through the bottom guide wheel 4.3.3 and the two side guide wheels 4.3.4, respectively. This not only includes the rolling contact between the guide mechanism 4.3 and the bridge body 1, but also prevents the guide mechanism 4.3 from detaching from the bridge body 1. The side wall of the guide seat 4.3.1 is curved, and the curved surface is concave away from the inner wall of the mounting sleeve 4.1, so that it can cooperate with the mounting sleeve 4.1 to limit the hinge angle, so that the bottom guide wheel 4.3.3 and the side guide wheels 4.3.4 always maintain contact with the bridge body 1.

[0036] In addition, such as Figure 8The adjustable-angle movable truss bridge also includes a cable-stayed device 2. The cable-stayed device 2 includes a column 2.1, a pulley 2.2, a cable-stayed drive mechanism 2.3, and a cable 2.4. The column 2.1 is vertically mounted on the bridge body 1; the pulley 2.2 is located at the top of the column 2.1; the cable-stayed drive mechanism 2.3 is located at the first end of the bridge body 1; the first end of the cable 2.4 is connected to the output end of the cable-stayed drive mechanism 2.3, and the second end of the cable 2.4 is connected to the second end of the bridge body 1 via the pulley; the cable-stayed drive mechanism 2.3 includes a mounting base 2.3.1 and a cable-stayed drive component 2.3.2. The second anchor box 2.3.4 and the third anchor box 3.1.3 are mounted on the bridge body 1 with the mounting base 2.3.1 inclined towards the column 2.1 in a vertically upward direction. The cable-stayed drive component 2.3.2 is mounted on the mounting base 2.3.1 and is coaxial with the mounting base 2.3.1. The second anchor box 2.3.4 is connected to the output shaft of the cable-stayed drive component 2.3.2. The third anchor box 3.1.3 is mounted on the bridge body 1, and the two ends of the cable stay 2.4 are connected to the second anchor box 2.3.4 and the third anchor box 3.1.3 respectively. At the second end of the bridge body 1, a cable seat 2.3.5 is provided for the installation of the stay cable 2.4. The cable-stayed drive mechanism 2.3 can pull the second end of the bridge body 1 through the stay cable 2.4. The stay cable 2.4 is pulled by the cable-stayed drive component 2.3.2, and the tension and stroke are adjustable. By adjusting the stroke and tension of the cable-stayed drive component 2.3.2, the deformation of the stay cable 2.4 under tension during the extension, contraction or rotation of the bridge body 1 can be compensated, thereby controlling the deflection of the bridge body 1. The tension of the stay cable 2.4 can be adjusted according to the hydraulic pressure to adapt to various length extensions. The cable-stayed drive component 2.3.2 and the mounting seat 2.3.1 can be hinged, which is beneficial to the force on the cable-stayed drive component 2.3.2. The cable-stayed drive component 2.3.2 can be a hydraulic cylinder, a combination of turnbuckle and tension sensor, or an electric winch. The cable-stayed device 2 also includes an auxiliary tie rod 2.5, which is connected between the column 2.1 and the bridge body 1 to support the column 2.1.

[0037] like Figure 3 and Figure 4 As shown, in one embodiment, there are two cable-stayed devices 2, which are respectively located on both sides of the bridge body 1 in the width direction. The use of two cable-stayed devices 2 helps to improve the overall structural stability.

[0038] like Figure 9As shown, the angle-adjustable movable truss bridge also includes a traveling articulation device 5, which includes a guide rail 5.1, a movable seat 5.2, and a hinge seat 5.3. The guide rail 5.1 is mounted on the hull 8 along a first direction; the movable seat 5.2 is equipped with a traveling member 5.2.1, and the movable seat 5.2 is slidably mounted on the guide rail 5.1 via the traveling member 5.2.1; the hinge seat 5.3 is located at the bottom of the bridge body 1, and is hinged to the movable seat 5.2 via a pin 5.4. The bridge body 1 can move along the guide rail 5.1 via the movable seat 5.2 to change the extension length of the bridge body 1, and the angle of the bridge body 1 can be adjusted by rotating the hinge seat 5.3 relative to the movable seat 5.2, thereby adapting to different terrains and water levels on the shoreline 9.

[0039] In addition, the main body of the bridge 1 includes a truss structure 1.1, a bridge deck 1.2, and two support seats 1.3. The bridge deck 1.2 is welded to the truss structure 1.1. The two support seats 1.3 are spaced apart at the bottom of the truss structure 1.1, and each support seat 1.3 is equipped with a lifting device 4. The truss structure 1.1 includes multiple trusses, which are welded to the two support seats 1.3. Different numbers of truss rows are selected according to different traffic load levels to meet different traffic load requirements. The bridge deck 1.2 is installed on the truss structure 1.1 and is made of cross-welded transverse and longitudinal steel sections, which effectively improves the load-bearing capacity. Furthermore, both ends of the bridge deck 1.2 are provided with inclined surfaces sloping downwards in a first direction. See also... Figure 5 The lifting device 4 includes multiple lifting drive components 4.2, which are spaced apart within the mounting sleeve 4.1. The lifting device 4 lifts the corresponding support base 1.3 to ensure operational stability. The multiple lifting drive components 4.2 work together to improve operational efficiency and ensure operational safety.

[0040] The angle-adjustable movable truss bridge also includes a first ramp 6 and a second ramp 7, which are respectively hinged to both ends of the bridge body 1. The first ramp 6 is used to connect with the hull 8, and the second ramp 7 is used to connect with the shore foundation 9. The first ramp 6 and the second ramp 7 are respectively hinged on the inclined surfaces at both ends of the bridge deck 1.2 and connect with the hull 8. Due to the hinged installation, the first ramp 6 can connect with the hull 8 regardless of the angle between the bridge body 1 and the hull 8, while the second ramp 7 can be flipped by external force to connect with the shore foundation 9.

[0041] like Figure 10 As shown, when the bottom surface of the shore base 9 is at the same height as the support base 1.3, the bridge body 1 is extended to the shore base 9 by the moving mechanism 3.1 close to the shore base 9, and the two moving mechanisms 3.1 are locked. Then the second scaffold 7 is flipped from the bridge body 1 and attached to the shore base 9, thereby realizing the connection between the ship hull 8 and the shore base 9.

[0042] like Figure 11 As shown, when the shore base 9 is higher than the bottom surface of the support base 1.3, when the moving mechanism 3.1 near the shore base 9 drives the bridge body 1 to extend close to the shore base 9, the piston rod of the lifting drive component 4.2 in the lifting device 4 extends out and pushes the second end of the bridge body 1 upward through the bottom guide wheel 4.3.3 and the side guide wheel 4.3.4 in the guide mechanism 4.3. At the same time, it rotates around the fixed base through the pin 5.4, and the moving mechanism 3.1 near the shore base 9 continues to pull the bridge body 1 to move until the second end of the bridge body 1 extends onto the shore base 9. At this time, the second ramp 7 is flipped to overlap with the shore base 9 to achieve the connection between the hull 8 and the shore base 9. Finally, the two moving drive components 3.1.1 are locked to build a solid and stable fast passage.

[0043] When it is necessary to retract the bridge body 1, first flip the second ramp 7 so that it overlaps the bridge deck 1.2, then unlock the two moving drive components 3.1.1, and the moving mechanism 3.1 away from the shore base 9 pulls the bridge body 1 to move in the opposite direction of the first direction. After the bridge body 1 exits the shore base 9, the output shaft of the lifting drive component 4.2 of the lifting device 4 is retracted, so that the bridge body 1 rotates to be horizontal with the hull 8, while the moving mechanism 3.1 away from the shore base 9 continues to pull the bridge body 1 until the bridge body 1 is retracted to the initial state.

[0044] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
