Description

Technical Field

[0001] The invention relates to the field of translational bridges, and in particular to a translational device for bridge rotation. Background Art

[0002] A pivoting bridge is a special type of bridge structure that allows the bridge to be rotated in the horizontal plane, thereby opening and closing the bridge. This type of bridge is mainly used in situations where the channel needs to be frequently opened for ships to pass, such as canals, ports and narrow rivers.

[0003] The existing translation device for bridge rotation realizes the rotation of the bridge column on the load-bearing platform through the ball joint of the upper and lower parts. When the bridge column rotates, it is supported and stabilized by the tripod on the lower side, and the tripod is counterweighted by a sand bucket. However, when the bridge is laid on the bridge column, the weight at both ends of the bridge may be inconsistent due to design errors, which leads to uneven load-bearing on the bridge column and tilting of the tripod. The sand bucket on the tripod cannot increase the counterweight, and it is not convenient to adjust the weight of the tripod according to the load-bearing condition of the bridge column, which is relatively inconvenient.

[0004] Therefore, a swivel device for rotating the bridge has been developed which can adjust the weight of the support frame according to the load-bearing condition of the bridge column to ensure that the bridge column is in a horizontal state. Summary of the invention

[0005] In order to overcome the disadvantage that the sand bucket on the tripod cannot be used to increase the counterweight in the existing bridge rotation device, and thus it is inconvenient to adjust the weight of the tripod according to the load-bearing conditions of the bridge column, the present invention provides a bridge rotation device that can adjust the weight of the tripod according to the load-bearing conditions of the bridge column to ensure that the bridge column is in a horizontal state.

[0006] The technical solution is: a translation device for bridge rotation, including a load-bearing platform, a connecting frame, a lower half of a ball hitch, a slide, a casting block, an upper half of a ball hitch, a bridge column, a rotating assembly and a counterweight assembly. The upper side of the load-bearing platform is connected to the connecting frame, the lower half of the ball hitch is connected to the connecting frame, the upper side of the load-bearing platform is connected to the slide, the slide is located outside the connecting frame, the load-bearing platform is connected to the casting block, the connecting frame and the slide are both located inside the casting block, the upper side of the lower half of the ball hitch is clamped with the upper half of the ball hitch, the upper side of the upper half of the ball hitch is connected to the bridge column, the bridge column is provided with a rotating assembly that can rotate, and the bridge column is also provided with a counterweight assembly that can maintain balance.

[0007] As a further preferred scheme, the rotating assembly includes a fixed block, a connecting pin, a connecting bracket, a roller and a connecting ring. A plurality of fixed blocks are connected to the outside of the bridge column. The fixed blocks are all threadedly connected to connecting pins, two of which are connected to connecting rings, and the connecting rings are symmetrically arranged. The remaining connecting pins are connected to connecting brackets, and the connecting brackets are rotatably connected to rollers.

[0008] As a further preferred scheme, the counterweight assembly includes a tripod, a sand bucket, an empty bucket, a connecting cover and a connecting cylinder. A plurality of sand buckets are connected to the lower side of the bridge column, and the sand buckets are all connected to a tripod. The tripods are all located on the upper side of the slideway. The tripods are all connected to empty buckets, and the empty buckets are all connected to the bridge column. The empty buckets are all rotatably connected to a connecting cover, and the middle of the tripods are connected to a connecting cylinder. When the load on the bridge column is uneven, the bridge column tilts to the heavier side so that the tripod in the corresponding position is close to the slideway. Then the connecting cover is opened, and sand or counterweights are added to the empty buckets in the opposite direction of the tilt of the bridge column to balance the weight on both sides of the bridge column and restore the bridge column to a level state.

[0009] As a further preferred solution, a handle is provided on the connecting cover.

[0010] As a further preferred solution, support blocks are provided on the telescopic ends of the connecting cylinders.

[0011] As a further preferred solution, a temporary support cylinder is also included. A plurality of temporary support cylinders are detachably connected to the upper side of the slideway by bolts, and the temporary support cylinders are all located below the bridge column.

[0012] As a further preferred solution, a top block is provided on the telescopic end of the temporary support cylinder.

[0013] As a further preferred scheme, the pulling assembly includes a fixed frame, a motor, a wire wheel and a steel cable. The fixed frame is connected to the upper left front part of the casting block, the fixed frame is connected to the motor, the wire wheel is connected to the motor output shaft, the wire wheel is rotatably connected to the fixed frame, a steel cable is wound around the wire wheel, and the other end of the steel cable is installed on one of the connecting rings. The steel cable contacts the roller, and the motor is started to drive the wire wheel to rotate, so that the steel cable is recovered, so that the bridge column rotates, and then the bridge is driven to rotate.

[0014] As a further preferred scheme, the limiting assembly includes a limiting plate, a connecting support frame, a rotating frame, a rotating plate and a first spring. The limiting plate is connected to the upper side of the casting block, the limiting plate is located outside the slideway, and multiple connecting support frames are connected to the outer side of the lower part of the bridge column. The lower side of the connecting support frames is rotatably connected to the rotating frame, and the rotating frame is rotatably connected to the rotating plate. The rotating plate and the limiting plate are extruded and matched, and the first spring is connected between the rotating plate and the connected rotating frame. When the bridge column rotates, the connecting support frame is driven to rotate. When the rotating plate on the rotating frame contacts the limiting plate, the rotating plate rotates, and the first spring is squeezed and contracted. When the bridge column rotates in the opposite direction, the rotating frame limits the rotating plate.

[0015] As a further preferred scheme, the prompt component includes a guide column, a second spring, a button and a prompter. The lower part of the rotating frame is slidably connected to the guide column, the guide column is squeezed together with the adjacent rotating plate, and multiple second springs are connected between the guide column and the connected rotating frame. Initially, the second spring is in a compressed state. The rotating frame is connected to the prompter, and the prompter is slidably connected to the button. The guide column is squeezed together with the adjacent button. When the rotating plate contacts and rotates with the limit plate, the rotating plate separates from the guide column, and the second spring rebounds, causing the guide column to move away from the button, and the prompter emits a prompt sound. After the rotating plate is separated from the limit plate and reset, the guide column is squeezed to reset, so that the guide column presses the button, and the prompter is closed.

[0016] The present invention has the following advantages: 1. When the load on the bridge column is uneven, the bridge column tilts to the heavier side, the connecting cover is opened, and sand or counterweights are added to the empty bucket in the opposite direction of the tilt of the bridge column to balance the weight on both sides of the bridge column and restore the bridge column to a horizontal state, thereby achieving the effect of being able to adjust the weight of the tripod according to the load-bearing condition of the bridge column to ensure that the bridge column is in a horizontal state.

[0017] 2. The present invention installs the connecting pin on the fixed block, and then installs the fixed frame on the casting block. Thereafter, one end of the steel cable is connected to one of the connecting rings, and the steel cable is contacted with the roller on the connecting bracket. When the bridge needs to rotate, the motor is started to drive the wire wheel to rotate, and the steel cable is recovered to rotate the bridge column, thereby achieving the effect of being able to install the steel cable on the outside of the bridge column, facilitating the disassembly and replacement of the steel cable, and avoiding aging of the steel cable.

[0018] 3. The present invention installs a temporary support cylinder on a slideway so that the top block on the temporary support cylinder temporarily supports the bridge column, thereby achieving the effect of being able to temporarily support the bridge column conveniently and quickly, thereby improving ease of use.

[0019] 4. The present invention drives the connecting support frame to rotate while the bridge column rotates. When the rotating plate on the rotating frame contacts the limiting plate, the rotating plate rotates, and the first spring is squeezed and contracted. When the bridge column rotates in the opposite direction, the rotating frame limits the rotating plate, thereby achieving the effect of limiting the bridge column and preventing the bridge column from rotating in the opposite direction.

[0020] 5. When the rotating plate of the present invention contacts and rotates with the limit plate, the rotating plate separates from the guide column, and the second spring rebounds, causing the guide column to move and separate from the button. The indicator emits a prompt sound, and after the rotating plate separates from the limit plate and resets, the guide column is squeezed to reset, causing the guide column to press the button, and the indicator is closed, thereby achieving the effect of being able to prompt the rotation angle of the bridge column, so as to control the bridge column to rotate to the appropriate position.

[0041] like Fig.13 and Fig.14 As shown, the limit assembly includes a limit plate 14, a connecting support frame 15, a rotating frame 16, a rotating plate 17 and a first spring 18. The upper side of the casting block 5 is connected to the limit plate 14, the limit plate 14 is located outside the slideway 4, and three connecting support frames 15 are connected to the outer side of the lower part of the bridge column 7. The lower side of the connecting support frames 15 is rotatably connected to the rotating frame 16, and the rotating frame 16 is rotatably connected to the rotating plate 17. The rotating plate 17 is pressed and fitted with the limit plate 14, and the first spring 18 is connected between the rotating plate 17 and the connected rotating frame 16.

The rotating frame 16 is connected to the prompter 22, and the prompter 22 is slidably connected to the button 21. The guide column 19 is squeezed and matched with the adjacent button 21.

[0043] When using the present invention, first cast the load-bearing platform 1 in the rotating bridge area. When the load-bearing platform 1 is cast to the ground level, install the connecting frame 2 at the center of the load-bearing platform 1, then install the lower half 3 of the ball hook 3 on the connecting frame 2, and install the slide 4 on the load-bearing platform 1. Then cast the casting block 5 outside the connecting frame 2 and the slide 4, so that the slide 4 is higher than the top surface of the casting block 5, and then place the upper half 6 of the ball hook on the lower half 3 of the ball hook, cast the bridge column 7 on the upper half 6 of the ball hook, and at the same time, pre-embed the fixing block 70, the sand bucket 80 and the empty bucket 81 in the bridge column 7, and then the connecting pin 7 1 is installed on the fixing block 70, and then the fixing frame 10 is installed on the casting block 5, and then one end of the steel cable 13 is connected to one of the connecting rings 74, and the steel cable 13 is brought into contact with the roller 73 on the connecting bracket 72. When the bridge needs to rotate, the motor 11 is started to drive the wire wheel 12 to rotate, and the steel cable 13 is recovered, so that the bridge column 7 rotates, and then the bridge is driven to rotate, and the upper half of the ball hitch 6 rotates on the lower half of the ball hitch 3, so that the steel cable 13 can be installed on the outside of the bridge column 7, which is convenient for disassembly and replacement of the steel cable 13 and avoids aging of the steel cable 13. When the bridge column 7 rotates, the tripod 8 is driven to rotate. The sand bucket 80 increases the stability of the bridge column 7 when it rotates. When the load on the bridge column 7 is uneven, the bridge column 7 tilts to the heavier side, so that the tripod 8 in the corresponding position is close to the slide 4. The support block on the telescopic end of the connecting cylinder 83 supports the bridge column 7 to prevent the bridge column 7 from tilting significantly. Then, the connecting cover 82 is opened, and sand or counterweight blocks are added to the empty bucket 81 in the opposite direction of the tilt of the bridge column 7 to balance the weight on both sides of the bridge column 7 and restore the bridge column 7 to the level, thereby playing the role of being able to adjust the weight of the tripod 8 according to the load-bearing situation of the bridge column 7 to ensure that the bridge column 7 is in a horizontal state. When the bridge column 7 is cast, the temporary support cylinder 9 can be installed on the slide 4, so that the top block on the temporary support cylinder 9 temporarily supports the bridge column 7, thereby playing the role of being able to conveniently and quickly temporarily support the bridge column 7 and improve the convenience of use. After the bridge column 7 is formed, the temporary support cylinder 9 is removed to avoid affecting the rotation of the bridge column 7. The limit plate 14 is installed on the upper casting block 5. When the bridge column 7 rotates, the connecting support frame 15 is driven to rotate. When the rotating plate 17 on the rotating frame 16 contacts the limit plate 14, the rotating plate 17 rotates, and the first spring 18 is squeezed and contracted. When the bridge column 7 rotates in the opposite direction, the rotating frame 16 limits the rotating plate 17 to prevent the bridge column 7 from reversing. After the rotating plate 17 is separated from the limit plate 14, the first spring 18 rebounds to reset the rotating plate 17, thereby limiting the bridge column 7 and preventing the bridge column 7 from rotating in the opposite direction. When the bridge column 7 needs to rotate in the opposite direction, the rotating frame 16 is turned to adjust the angle of the rotating plate 17.When the rotating plate 17 contacts and rotates with the limit plate 14, the rotating plate 17 disengages from the guide column 19, and the second spring 20 rebounds, causing the guide column 19 to move away from the button 21, and the indicator 22 emits a prompt sound. After the rotating plate 17 disengages from the limit plate 14 and resets, the guide column 19 is squeezed to reset, causing the guide column 19 to press the button 21, and the indicator 22 is closed, thereby providing a prompt for the rotation angle of the bridge column 7, so as to facilitate the control of the bridge column 7 to rotate to a suitable position.
