Description

Technical Field

[0001] This utility model belongs to the technical field of factory maintenance bridge or emergency passage setting, specifically a flip-type bridge passage. Background Technology

[0002] To improve production efficiency, save labor costs, or for layout purposes, factories often equip themselves with automated production lines or transport equipment that travels along fixed routes. Sometimes, even long trenches are dug at the equipment locations. These production lines, transport equipment, or trenches inadvertently block lateral passageways perpendicular to the equipment. When maintenance or emergency needs arise, time-consuming or labor-intensive methods must be used to move emergency vehicles or goods that require lateral passage. For example, if an emergency vehicle needs to cross a factory building with a trench, and the ground conditions exceed the vehicle's lateral travel capacity, it must detour around the factory building to reach the destination. This longer detour undoubtedly wastes valuable time, especially in emergency situations.

[0003] Currently, most maintenance paths within the factory that require crossing equipment are traversed by steps on both sides of the equipment, which are elevated above ground level, to facilitate the passage of workers. For shallow trenches, or those containing equipment or ground rails that make it difficult for vehicles to pass, large and heavy temporary bridges are typically constructed. These bridges need to be erected and dismantled promptly before and after each use, requiring significant manpower and resources. Furthermore, they are slow to set up and take up a large area when deployed or retracted. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a flip-type bridge passage.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A flip-type bridge passage includes an outer frame, a fixed base, a flip-type bridge body, and a traction rope assembly;

[0007] The fixed base is fixed to the ground and located on one side of the corresponding trench. The outer frame is fixed to the ground and located outside the fixed base. A hinge shaft is provided on the side of the fixed base. The fixed base is hinged to the side of the flip bridge body through the hinge shaft.

[0008] The upper part of the fixed base is provided with the traction rope assembly, and the tilting bridge body is driven by two sets of corresponding traction rope assemblies and tilts and rises and falls around the axis of the corresponding hinge shaft.

[0009] Each of the aforementioned traction rope assemblies includes a drum mounting bracket, a drum, a traction rope, and a winch motor;

[0010] Each set of traction rope assembly drum mounting brackets is fixedly connected to the upper part of the outer frame. Each set of traction rope assembly drums is rotatably mounted in the drum mounting bracket of the same set of traction rope assembly. The housing of each set of traction rope assembly winch motors is fixedly connected to the drum mounting bracket of the same set of traction rope assembly. The drive end of each set of traction rope assembly winch motors is connected to the rotating shaft of the drum of the same set of traction rope assembly and is used to drive the drum to rotate. One end of the traction rope of the same set of traction rope assembly is fixedly connected to the drum of each set of traction rope assembly. The other end of the traction rope of each set of traction rope assembly is used to connect to one side of the corresponding tilting bridge body. The other ends of the traction ropes of two sets of traction rope assemblies are used to connect to two sides of the corresponding tilting bridge body located in opposite directions.

[0011] The flip bridge body is provided in two parts, and the two flip bridge bodies are respectively located on the left and right sides of the outer frame;

[0012] The two sets of traction rope assemblies are positioned symmetrically on the outer frame. Each set includes two traction ropes. One end of each traction rope in the same set is fixed to the drum of the same set. The other end of one traction rope in the front set wraps around the drum several times before connecting to the front side of one of the corresponding tilting bridge bodies. The other end of the other traction rope in the front set wraps around the drum several times before connecting to the front side of the corresponding other tilting bridge body. The rear set of traction rope assemblies... One end of one of the traction ropes is wound around the drum of the same traction rope assembly several times and then connected to the rear side of one of the corresponding flipping bridge bodies. The other end of the other traction rope of the traction rope assembly located on the rear side is wound around the drum of the same traction rope assembly several times and then connected to the rear side of the corresponding other flipping bridge body. The two traction ropes on the drum of each traction rope assembly are wound in the same direction. The connection position of the other end of each traction rope of the traction rope assembly located on the front side to the corresponding flipping bridge body corresponds to the connection position of the other end of each traction rope of the traction rope assembly located on the rear side to the corresponding flipping bridge body.

[0013] Each of the flipping bridge bodies is provided with connecting ears on its front and rear sides for connecting with a traction rope, and each connecting ear is used in conjunction with a corresponding traction rope.

[0014] The other end of each traction rope is connected to a rope clamp and a shackle, and the other end of each traction rope is connected to a corresponding connecting ear of the flipping bridge body through the connected shackle.

[0015] The axial centerlines of the drums of the two sets of traction rope assemblies are collinear; the projection of the axial centerline of each drum onto the horizontal plane is located on one side of the projection of the centerline of the fixed base parallel to the front-back direction onto the horizontal plane, and the projection of the tangent point between the traction rope of each set of traction rope assemblies and the drum of the same set of traction rope assemblies onto the horizontal plane is located on the other side of the projection of the centerline of the fixed base parallel to the front-back direction onto the horizontal plane, so that the total flipping angle of the two flipping bridges is the same.

[0016] The flipping bridge body is provided with a bushing that cooperates with the hinge shaft to form a rotating pair.

[0017] The present invention provides a flip-type bridge passage, which further includes a high-position detection switch, a low-position detection switch, and a limit stop. The limit stop is disposed on the flip-type bridge body, and the high-position detection switch and the low-position detection switch are respectively disposed on the ground through detection switch brackets. When the other end of the flip-type bridge body flips up to a preset high position, one end of the limit stop on the flip-type bridge body triggers the high-position detection switch. When the other end of the flip-type bridge body flips down to a preset low position, the other end of the limit stop on the flip-type bridge body triggers the low-position detection switch.

[0018] The present invention proposes a flip-type bridge passage, which also includes a limiting and blocking frame installed on the ground. The limiting and blocking frame is used to block the flip-type bridge body when it rises above a preset height and to prevent the flip-type bridge body from flipping too much.

[0019] The top surface of the end of the flip bridge away from the fixed base has a transition slope.

[0020] The advantages and positive effects of this utility model are as follows:

[0021] This utility model, through the coordinated arrangement of an outer frame, a fixed base, a tilting bridge body, and a traction rope assembly, hardly affects the original appearance of the trench or the original factory equipment structure. Normally, the tilting bridge body is raised without affecting the normal operation of the equipment in the trench. When needed, the tilting bridge body can be lowered to facilitate the lateral passage of vehicles or maintenance personnel through the trench obstacles at the constructed location. There is no need for repeated assembly and disassembly, and it is easy to achieve automated control. It can be used in conjunction with other equipment signals to ensure safety and is compatible with automated environments. Attached Figure Description

[0030] 001 represents the ground surface, and 002 represents the trench. Detailed Implementation

[0031] The following is in conjunction with the appendix Figure 1-7 The present invention will be described in further detail.

[0032] A type of flip-over bridge passage, such as Figure 1-7 As shown, this embodiment includes an outer frame 1, a fixed base 2, a tilting bridge body 3, and a traction rope assembly. In this embodiment, as... Figure 1 As shown, the direction parallel to trench 002 is the front-to-back direction, and the direction perpendicular to trench 002 is the left-to-right direction.

[0033] The fixed base 2 is fixed to the ground 001 by anchor bolts and is located on one side of the corresponding trench 002. The outer frame 1 is fixed to the ground 001 by anchor bolts and is located outside the fixed base 2. A hinge shaft 201 is provided on the side of the fixed base 2, and the fixed base 2 is hinged to the side of the tilting bridge 3 through the hinge shaft 201. A traction rope assembly is provided on the upper part of the fixed base 2. The tilting bridge 3 is driven by two sets of corresponding traction rope assemblies and tilts and rises around the axis of the corresponding hinge shaft 201. A bushing is provided on the tilting bridge 3 to cooperate with the hinge shaft 201 and form a rotating pair to ensure smooth tilting of the tilting bridge 3. The setting method of the hinge shaft 201 and the bushing adopts existing technology. Under the drive of the two sets of corresponding traction rope assemblies, the end of the tilting bridge 3 away from the fixed base 2 is lifted so that moving objects in the trench 002 can pass through normally. After being lifted, the tilting bridge 3 can be stored almost perpendicular to the horizontal plane, saving space. The end of the tilting bridge body 3 away from the fixed base 2 can be placed on the side of the trench 002 away from the fixed base 2 so that vehicles and personnel can pass through the trench 002 laterally. At this time, the top surface of the tilting bridge body 3 and the top surface of the fixed base 2 together form a passable road surface.

[0034] Each traction rope assembly includes a drum mounting frame 4, a drum 5, a traction rope 6, and a winch motor 7. Two corresponding traction rope assemblies use components with the same structure. The drum mounting frame 4 of each traction rope assembly is fixed to the upper part of the outer frame 1. The drum 5 of each traction rope assembly is rotatably mounted in the drum mounting frame 4 of the same traction rope assembly. The housing of the winch motor 7 of each traction rope assembly is fixed to the drum mounting frame 4 of the same traction rope assembly. The drive end of the winch motor 7 of each traction rope assembly is connected to the rotating shaft of the drum 5 of the same traction rope assembly and is used to drive the drum 5 to rotate. One end of the traction rope 6 of the same traction rope assembly is fixed to the drum 5 of each traction rope assembly. The other end of the traction rope 6 of each traction rope assembly is used to connect to one side of the corresponding tilting bridge body 3. The other ends of the traction ropes 6 of the two traction rope assemblies are used to connect to two sides of the corresponding tilting bridge body 3 located in opposite directions. Two winch motors 7 synchronously power the tilting bridge 3, reducing the size and power of a single winch motor 7. Since the tilting bridge 3 is driven simultaneously from both sides by the traction ropes 6 of two sets of traction rope assemblies, the tension on the tilting bridge 3 is evenly distributed, saving passage space directly above the bridge passage. When the winch motors 7 release the traction ropes 6, it must be ensured that the tilting bridge 3 can fall to the required position by gravity. All winch motors 7 are controlled by an external control system, and all winch motors 7 are commercially available products. The external control system utilizes existing technology and can receive call signals requiring automated control, such as automated equipment signals or emergency alarm signals. For example, when the fire system issues an alarm signal, the tilting bridge passage needs to fall immediately to facilitate the rapid arrival of fire trucks at the emergency location. The fire alarm signal can be connected to the external control system and control the winch motors 7 to lower the tilting bridge 3.

[0035] In one specific embodiment of this utility model, such as Figure 1-4 As shown, the fixed base 2 is located between two parallel trenches 002. At this time, there are two flip bridge bodies 3. The two flip bridge bodies 3 are located on the left and right sides of the outer frame 1 respectively. The two flip bridge bodies 3 can be controlled by two sets of traction rope assemblies to move together, so as to facilitate passing through the two parallel trenches 002 at one time.

[0036] The two sets of traction rope assemblies are positioned in a front-to-back correspondence on the outer frame 1. Each set of traction rope assemblies includes two traction ropes 6. One end of each of the two traction ropes 6 in the same set of traction rope assemblies is fixed to the drum 5 of the same set of traction rope assemblies. The other end of one of the traction ropes 6 in the front set of traction rope assemblies is wound around the drum 5 of the same set of traction rope assemblies several times and then connected to the front side of one of the corresponding flipping bridge bodies 3. The other end of the other traction rope 6 in the front set of traction rope assemblies is wound around the drum 5 of the same set of traction rope assemblies several times and then connected to the front side of the other corresponding flipping bridge body 3. The other end of one of the traction ropes 6 in the rear set of traction rope assemblies is wound around the drum 5 of the same set of traction rope assemblies several times and then connected to the rear side of one of the corresponding flipping bridge bodies 3. The other end of the other traction rope 6 in the rear set of traction rope assemblies is wound around the drum 5 of the same set of traction rope assemblies several times and then connected to the rear side of the other corresponding flipping bridge body 3. The two traction ropes 6 on the drum 5 of each traction rope assembly are wound in the same direction (i.e., viewed from the trench 002 or the equipment along the front-to-back direction, they are wound clockwise or counterclockwise). Each drum 5 can be two coaxially connected parts, each part corresponding to one traction rope 6. The connection position of the other end of each traction rope 6 of the front traction rope assembly to the corresponding tilting bridge body 3 corresponds to the connection position of the other end of each traction rope 6 of the rear traction rope assembly to the corresponding tilting bridge body 3.

[0037] Each of the two sides of the flip bridge body 3 is provided with connecting ears 301 for connecting to the traction rope 6. Each connecting ear 301 is used in conjunction with a corresponding traction rope 6, so that the connected traction rope 6 does not occupy the allowable width space of the bridge passage. Figure 5 As shown, each traction rope 6 has a rope clamp 8 and a shackle 9 connected to its other end. The rope clamp 8 forms a loop on the other end of the traction rope 6 for easy connection with the shackle 9. The other end of each traction rope 6 is connected to a corresponding connecting ear 301 of the tilting bridge body 3 via the connected shackle 9. The connection method between the shackle 9 and the connecting ear 301 adopts existing technology. This arrangement facilitates the assembly and disassembly of the traction rope 6 and the tilting bridge body 3.

[0038] like Figure 1 , Figure 4 and Figure 6As shown, the axial centerlines of the drums 5 of the two sets of traction rope assemblies are collinear; the projection of the axial centerline of each drum 5 onto the horizontal plane is located to the left of the projection of the centerline of the fixed base 2 parallel to the front-back direction onto the horizontal plane. The projection of the tangent point of the traction rope 6 of each set of traction rope assemblies and the drum 5 of the same set of traction rope assemblies onto the horizontal plane is located to the right of the projection of the centerline of the fixed base 2 parallel to the front-back direction onto the horizontal plane, making the total tilting angle of the two tilting bridge bodies 3 the same, so that the two tilting bridge bodies 3 can be stably driven to rise and fall by the same amount at the same time. If it is necessary for the two tilting bridge bodies 3 to tilt at different angles, the position of the drum 5 relative to the fixed base 2 and the adjacent trench 002 can be arbitrarily adjusted according to the usage requirements.

[0039] In one specific embodiment of this utility model, such as Figure 4 and Figure 7 As shown, the tilting bridge passage also includes a high-position detection switch 10, a low-position detection switch 11, a limit stop bar 12, and a limit blocking frame 14. The limit stop bar 12 is mounted on the tilting bridge body 3, and the high-position detection switch 10 and the low-position detection switch 11 are respectively mounted on the ground 001 via detection switch brackets 13. The mounting method of the detection switch brackets 13 adopts existing technology. When the other end of the tilting bridge body 3 tilts and rises to a preset high position, one end of the limit stop bar 12 mounted on the tilting bridge body 3 triggers the high-position detection switch 10. When the other end of the tilting bridge body 3 tilts and falls to a preset low position, the other end of the limit stop bar 12 mounted on the tilting bridge body 3 triggers the low-position detection switch 11. The high-position detection switch 10 and the low-position detection switch 11 are commercially available products and are respectively connected to an external control system. When the high-position detection switch 10 and the low-position detection switch 11 are triggered, signals are sent to the external control system, which then controls the hoisting motor 7 to stop, preventing overtravel of the hoist from affecting other components or equipment. The limit stop 14 is set on the ground 001 to block the tilting bridge 3 when it rises above the preset high position and prevents it from tilting too much, ensuring that the tilting bridge 3 can fall back to the ground 001 by gravity.

[0040] In one specific embodiment of this utility model, such as Figure 3 and Figure 4 As shown, a transition slope 302 is formed on the top surface of the end of the tilting bridge body 3 away from the fixed base 2, which facilitates the movement of vehicles along the transition slope 302 onto the tilting bridge body 3 and through the tilting bridge passage.
