Description

Technical Field

[0001] This application relates to the field of hanging basket technology, specifically to a hanging basket for construction of multi-truss ultra-wide bridges and its working method. Background Technology

[0002] Bridge engineering mainly studies bridge design, determines bridge span, considers navigation and route requirements to determine bridge deck height, considers the foundation to prevent scouring or frost heave to determine foundation depth, designs diversion structures, bridge scheme design, bridge structural design, bridge construction, bridge inspection, bridge testing and bridge maintenance, etc. Bridge construction requires the use of hanging baskets. The existing formwork for multi-truss ultra-wide bridge construction is not very effective. The formwork moves slowly and cannot meet the time requirements for formwork movement in the construction plan, resulting in delays in the connection between various construction stages and thus extending the overall construction period of the bridge. Summary of the Invention

[0003] The purpose of this invention is to provide a hanging basket for the construction of multi-truss ultra-wide bridges, which solves the problem that the existing hanging baskets for the construction of multi-truss ultra-wide bridges have poor movement performance and cannot meet the time requirements for the movement of the hanging basket in the construction plan.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A multi-truss type ultra-wide bridge construction formwork includes a portal frame and a formwork body mounted on the portal frame. The portal frame includes two side legs and a crossbeam connecting the two side legs. The formwork body reciprocates along the crossbeam via a transmission device and a guide device mounted on the crossbeam. The transmission device includes a dual-axis motor, a first transmission gear located at the lower output end of the dual-axis motor, a dual-axis motor support frame, a formwork support plate fixed to the dual-axis motor support frame, a guide wheel on the formwork support plate, a first guide groove on the crossbeam, and a toothed belt on the crossbeam. The guide wheel moves along the first guide groove. The guide device includes a sliding block located below the first transmission gear and at the lower output end of the dual-axis motor, and also includes a second guide groove on the crossbeam and a guide rod connecting the inner wall of the second guide groove and penetrating the sliding block. The transmission device is equipped with a linkage oil delivery device for supplying lubricating oil to the transmission gear. The linkage oil delivery device includes an oil storage tank, an oil delivery pipe connected to the oil storage tank, and an inclined plate for supporting the oil delivery pipe. It also includes a drip-type oil delivery device. The drip-type oil delivery device includes a linkage device and a rotary oil delivery device. The linkage device includes a connecting box, a movable plate one limited to the connecting box, a control box mounted on a dual-axis motor support frame, a movable plate two limited to the control box, and a return spring. The movable plate one and the movable plate two are connected by a transmission line. The rotary oil conveying device includes a second transmission gear connected to the inclined plate via a bearing, a rack plate meshing with the second transmission gear, a connecting pipe connected to the second transmission gear, and several flow holes provided on the bottom wall of the connecting pipe. The oil conveying pipe extends into the connecting pipe. The end of the connecting pipe is sealed. A movable plate is limited to the connecting box and connected to the rack plate. The upper output end of the dual-axis motor extends into the control box, and two protrusions are symmetrically provided on both sides of this end. The control box is provided with a limiting plate for limiting the movable plate.

[0005] More preferably, the two inclined plates are symmetrically arranged on both sides of the dual-axis motor, the oil storage tank is arranged on the hanging basket support plate, and each inclined plate is provided with at least three transmission gears, each transmission gear corresponding to a connecting pipe. The oil supply pipe passes through the dual-axis motor support frame and the inclined plate and is connected to at least three connecting pipes. The flow hole of the connecting pipe is located directly above the space between the two toothed blocks.

[0006] More preferably, the control box is a rectangular box, and the four limiting plates are symmetrically arranged in pairs on both sides of the output end of the dual-axis motor; the two movable plates are symmetrically arranged on both sides of the protrusion. One end of the reset spring is fixed to the inner wall of the control box, and the other end is connected to the movable plate. The movable plate moves in the space between the limiting plates and the left and right side walls of the control box. The space between the limiting plates on the same side is through which the protrusion passes. The protrusion rotates around the axis and pushes the movable plate to move back and forth. The movable plate drives the movable plate to move back and forth through the transmission line, and then drives the rack and pinion gear to rotate.

[0007] Furthermore, the dual-axis motor support frame is a U-shaped plate with the slot facing downwards. The motor body of the dual-axis motor is fixed to the horizontal plate of the U-shaped plate. The dual-axis motor support frame includes two U-shaped frames with opposite slots. The slots of the two U-shaped frames are opposite each other and are respectively engaged with the two sides of the crossbeam. The lower side plates of the two U-shaped frames are connected and fixed to directly fix the hanging basket body. The guide wheels are located on the bottom surface of the upper side plate and the top surface of the lower side plate of the U-shaped frame. The guide groove is correspondingly set with the guide wheel. The two vertical parts of the U-shaped plate are connected and fixed to the two U-shaped frames.

[0008] Furthermore, two parallel tooth blocks on each side of the transmission gear mesh with each other.

[0009] In addition, the outriggers are hydraulic telescopic rods, and the bottom ends of the two hydraulic telescopic rods are fixedly connected to a base, and the base has multiple through-hole fixing holes.

[0010] Furthermore, two support rods are symmetrically fixedly connected to the upper surface of the hanging basket body, and the top ends of the multiple support rods are fixedly connected to the bottom surface of the dual-axis motor support frame. An openable protective door frame is fixedly connected to the side wall of the hanging basket body through a hinge.

[0011] More preferably, each of the oil tanks is provided with a liquid level display window on its opposite side, and each of the two oil tanks is provided with an addition port on its upper surface.

[0012] A working method for a hanging basket used in the construction of a multi-truss ultra-wide bridge is characterized in that: a dual-shaft motor drives a transmission gear to move back and forth along a toothed belt, which in turn drives the hanging basket body to move back and forth along the crossbeam. The dual-axis motor drives the cam to rotate, and the cam rotates around the axis to push the second movable plate to move back and forth. The second movable plate drives the first movable plate to move back and forth through the transmission line, which in turn drives the rack plate to rotate the second transmission gear. The forward and reverse rotation of the second transmission gear drives the connecting pipe to rotate in both directions to determine whether the lubricating oil drips.

[0013] Compared with the prior art, the present invention has the following features and beneficial effects: This application's dual-axis motor achieves uniform speed drive through the meshing of transmission gear one and toothed belt. Combined with the precise guidance of the gap between the guide rod and the sliding block in the guide groove one, the lateral offset of the hanging basket support plate is reduced when it moves, and the travel deviation of the multi-frame main truss of the ultra-wide hanging basket is reduced, avoiding the jamming and swaying problems of traditional roller movement. At the same time, the combination of hydraulic telescopic rod and base support, combined with the multi-point anchoring design of fixing holes, allows the hanging basket to adapt to the track slope when moving. Through the rolling constraint of the guide groove two and the roller, the vertical runout is reduced, ensuring the stability of the hanging basket during movement. The lubricating oil in the storage tank is guided to the connecting pipe by the inclined plate, and drips to the gear meshing part through the flow hole, avoiding wear caused by long-term use of the transmission structure. At the same time, the design of the liquid level display window and the filling port makes it easy to observe the oil level in real time, and the maintenance cycle is extended from frequent filling to regular replenishment, reducing downtime for maintenance.

[0014] This application uses the top of the output shaft of a dual-axis motor to drive a rotating rod and a protrusion to periodically press two movable plates. The two movable plates are controlled by air pressure to drive two rack plates, which in turn drive gears to adjust the angle of the connecting pipe. This allows the lubricating oil to dynamically adjust its dripping direction according to the gear meshing position, resulting in more comprehensive coverage and more efficient lubrication. At the same time, a return spring ensures the structure is cyclically reset, thereby further avoiding wear caused by long-term use of the transmission structure. Attached Figure Description

[0017] To make the technical means, innovative features, objectives and effects of this invention easier to understand, the invention will be further described below.

[0018] The embodiments described herein are specific implementations of the present invention, used to illustrate the concept of the invention, and are illustrative and exemplary, and should not be construed as limiting the implementation or scope of the invention. In addition to the embodiments described herein, those skilled in the art can employ other obvious technical solutions based on the content disclosed in the claims and specification of this application. These technical solutions include those that make any obvious substitutions and modifications to the embodiments described herein.

[0019] Example 1 A multi-truss type ultra-wide bridge construction formwork includes a portal frame 1 and a formwork body 2 mounted on the portal frame 1. The portal frame 1 includes two side legs 11 and a crossbeam 12 connecting the two side legs 11. The formwork body 2 reciprocates along the crossbeam 12 via a transmission device 3 and a guide device 4 mounted on the crossbeam 12. The transmission device 3 includes a dual-axis motor 31, a transmission gear 32 located at the lower output end of the dual-axis motor 31, a dual-axis motor support frame 33, and a dual-axis motor support frame 34. The dual-axis motor support frame 33 is connected to the fixed hanging basket support plate 34, the guide wheel 35 on the hanging basket support plate 34, the guide groove 36 on the crossbeam 12, and the toothed belt 37 on the crossbeam 12. The guide wheel 35 moves along the guide groove 36 and at the same time supports the hanging basket body 2 on the crossbeam 12. The two toothed belts 37 are arranged in parallel and form a fixed frame with the two side end plates. The dual-axis motor support frame 33 spans the fixed frame and is fixed to the top surface of the dual-axis motor support frame 33 on both sides. The guide device 4 includes a sliding block 41 located below the transmission gear 32 and at the lower output end of the dual-axis motor 31, and also includes a guide groove 42 located on the crossbeam 12 and a guide rod 43 connected between the inner walls of the guide groove 42 and passing through the sliding block 41. The lower output end should be rotatably connected to the sliding block 41. The guide rod 43 passes through the sliding block 41. The sliding block 41 is preferably a rectangular block structure, which is limited in the guide groove 42 and moves back and forth along the guide groove 42. The guide groove 42 is located on the top surface of the crossbeam 12 inside the fixed frame. The transmission device 3 is equipped with a linkage oil delivery device 5 for delivering lubricating oil to the transmission gear 32. The linkage oil delivery device 5 includes an oil storage tank 51, an oil delivery pipe 52 connected to the oil storage tank 51, and an inclined plate 53 for supporting the oil delivery pipe 52. It also includes a drip oil delivery device. The drip-type oil delivery device includes a linkage device 6 and a rotary oil delivery device 7. The linkage device 6 includes a connecting box 61, a movable plate 62 limited to the connecting box 61, a control box 63 mounted on a dual-shaft motor support frame 33, a movable plate 64 limited to the control box 63, and a return spring 65. The movable plate 62 and the movable plate 64 are connected by a transmission line 67. The rotary oil conveying device 7 includes a second transmission gear 71 connected to the inclined plate 53 via a bearing, a rack plate 72 meshing with the second transmission gear 71, a connecting pipe 73 connected to the second transmission gear 71, and several flow holes 74 provided on the inner bottom wall of the connecting pipe 73. The oil conveying pipe 52 extends into the connecting pipe 73, and the connecting pipe 73 can rotate with the second transmission gear 7. The end of the connecting pipe 73 is sealed, and the connecting pipe 73 is provided with flow holes 74. When the flow holes 74 are open upward, because the two ends of the connecting pipe 73 are sealed, the connecting pipe 73 does not pump oil into the first transmission gear. The first movable plate 62 is limited to the connecting box 61 and connected to the rack plate 72. The upper output end of the dual-axis motor 31 extends into the control box 63, and two protrusions 68 are symmetrically provided on both sides of this end. The control box 63 is provided with a limiting plate 69 for limiting the second movable plate 64. The first movable plate 62 moves back and forth on the internal space of the connecting box 61 as a track.

[0020] Example 2 Based on Embodiment 1, two inclined plates 53 are symmetrically arranged on both sides of the dual-axis motor 31, and the oil storage tank 51 is arranged on the hanging basket support plate 34. Each inclined plate 53 is provided with at least three transmission gears 71, and each transmission gear 71 corresponds to a connecting pipe 73. The oil supply pipe 52 passes through the dual-axis motor support frame 33 and the inclined plate 53 and connects with at least three connecting pipes 73. The flow hole 74 of the connecting pipe 73 is located directly above the meshing point between the toothed belt 37 and the transmission gear.

[0021] The control box 63 is a rectangular box. Four limiting plates 69 are symmetrically arranged in pairs on both sides of the output end of the dual-axis motor. Two movable plates 64 are symmetrically arranged on both sides of the protrusion 68. The protrusion 68 is preferably elliptical. A return spring is provided between the movable plate 64 and the inner wall of the control box 63. One end of the return spring 65 is fixed to the inner wall of the control box 63, and the other end is connected to the movable plate 64. Depending on whether the protrusion 68 abuts against the movable plate 64, the movable plate 64 moves in the space between the limiting plates 69 and the left and right side walls of the control box 63. The space between the limiting plates 69 on the same side is through which the protrusion 68 passes. The protrusion 68 rotates around the axis and pushes the movable plate 64 to move back and forth. The movable plate 64 drives the movable plate 62 to move back and forth through the transmission line 67, which in turn drives the rack plate 72 to rotate the transmission gear 71. The number of return springs 65 is set as needed. Several return springs 65 are symmetrically arranged on both sides of the protrusion 68, preferably four on one side.

[0022] Example 3 Based on Embodiment 2, the dual-axis motor support frame 33 is a U-shaped plate with the slot facing downwards. The motor body of the dual-axis motor 31 is fixed to the horizontal plate of the U-shaped plate. The dual-axis motor support frame 33 includes two U-shaped frames with opposite slots. The slots of the two U-shaped frames are opposite each other and are respectively engaged with the two sides of the crossbeam 12. The lower side plates of the two U-shaped frames are connected and fixed to directly fix the hanging basket body 2. Guide wheels 35 are provided on the bottom surface of the upper side plate and the top surface of the lower side plate of the U-shaped frame. Guide groove 36 is correspondingly provided with guide wheel 35. The two vertical parts of the U-shaped plate are connected and fixed to the two U-shaped frames. The two sides of the transmission gear 32 are connected to the guide wheel 35. Two parallel toothed blocks 37 are connected in mesh. The legs are hydraulic telescopic rods. The bottom ends of the two hydraulic telescopic rods are fixedly connected to bases 13. Multiple through-hole fixing holes are opened on the bases 13 for fixing to the bottom surface with anchors. Two support rods 21 are symmetrically fixedly connected to the upper surface of the basket body 2. The top ends of the multiple support rods 21 are fixedly connected to the bottom surface of the dual-axis motor support frame 33. The side wall of the basket body 2 is fixedly connected to an openable protective door frame 22 through hinges. Liquid level display windows are provided on opposite sides of the oil tanks 51. Addition ports are provided on the upper surface of the two oil tanks 51.

[0023] Example 4 Based on embodiment 3, the dual-axis motor 31 drives the transmission gear 32 to move back and forth along the toothed belt 37, which in turn drives the basket body 2 to move back and forth along the crossbeam 12. The dual-axis motor 31 drives the protrusion 68 to rotate. The rotation of the protrusion 68 around the axis pushes the second movable plate 64 to reciprocate. The second movable plate 64 drives the first movable plate 62 to reciprocate through the transmission line 67. In turn, it drives the rack plate 72 to rotate in conjunction with the second transmission gear 71. The forward and reverse rotation of the second transmission gear 71 drives the connecting pipe 73 to rotate in both directions to determine whether the lubricating oil drips. When the lubricating oil dripping is not required, the second movable plate 64 is moved away from the range of motion of the protrusion 68. At this time, the return spring 65 is in a compressed state, and the second movable plate 64 can be fixed in the control box by the limiting component.

[0024] Example 5 A hanging basket for construction of a multi-truss ultra-wide bridge and its working method are disclosed. The basket includes a crossbeam, with hydraulic telescopic rods symmetrically fixedly connected to the lower surface of the crossbeam. Each of the two hydraulic telescopic rods has a base fixedly connected to its bottom end. A hanging basket body is located below the crossbeam. A fixed frame is fixedly connected to the upper surface of the crossbeam. A through-type guide groove is opened on the lower inner surface of the fixed frame. Multiple toothed blocks are fixedly connected to the front and rear inner surfaces of the fixed frame. A hanging basket support plate is located on the outer side of the crossbeam. A sliding block is slidably connected inside the guide groove. The lower surface of the sliding block is fixedly connected to the upper inner wall of the hanging basket support plate. A dual-axis motor support frame is fixedly connected to the upper surface of the hanging basket support plate. A dual-axis motor is fixedly connected to the upper inner wall of the dual-axis motor support frame. A transmission gear is fixedly connected to the bottom end of the output shaft of the dual-axis motor. The bottom end of the output shaft of the dual-axis motor is rotatably connected to the upper surface of the sliding block. When the dual-axis motor starts, its output shaft drives the transmission gear to rotate clockwise or counterclockwise initially. Due to the meshing transmission between the toothed belt on the front and rear surfaces inside the fixed frame and the first transmission gear, the rotation of the first transmission gear is converted into the horizontal displacement of the sliding block in the first guide groove. The dual-axis motor support frame above the hanging basket support plate is rigidly connected to the dual-axis motor, ensuring no deviation during power transmission, thereby pushing the hanging basket body to move along the track direction. During the movement, the meshing between the first transmission gear and the toothed belt remains stable. The equidistant arrangement of the teeth on the toothed belt ensures that the displacement of the sliding block is consistent for every certain angle of rotation of the first transmission gear, thus making the moving speed of the hanging basket body uniform. When it is necessary to stop the movement, the dual-axis motor is de-energized, and the meshing of the first transmission gear and the toothed belt locks the position of the sliding block. Thus, through the rigid meshing transmission between the toothed belt and the first transmission gear, the moving distance can be precisely adjusted by controlling the speed of the dual-axis motor, improving the stability of the moving basket body.

[0025] Guide rods are fixedly connected to the inner left and inner right sides of guide groove one, and the outer wall of the guide rod is slidably connected to the inner side of the sliding block. When the dual-axis motor drives the sliding block to move, the guide rod restricts the lateral displacement of the sliding block, ensuring that the hanging basket support plate moves linearly along the axis of guide groove one, avoiding lateral sway caused by gear meshing error.

[0026] Both bases have multiple through-hole fixing holes on their upper surfaces; The hanging basket is fixed to the pre-embedded steel components through multiple fixing holes, thereby further improving the stability of the hanging basket's movement.

[0027] Two support rods are symmetrically fixedly connected to the upper surface of the hanging basket body, and the tops of multiple support rods are fixedly connected to the lower surface of the hanging basket support plate. A protective door frame is fixedly connected to the rear surface of the hanging basket body through a hinge. When the dual-axis motor drives the hanging basket support plate to move, the support rod transmits the horizontal thrust of the hanging basket support plate to the main truss of the hanging basket body, forming a rigid force transmission chain to prevent the hanging basket body from twisting due to horizontal force. At the same time, the protective gantry facilitates the entry of construction personnel or goods into the interior of the hanging basket body.

[0028] The upper surface of the crossbeam is provided with guide grooves 2 in front of and behind the fixed frame. Multiple rollers are provided on the upper surface of the inner wall of the hanging basket support plate above the two guide grooves 2. The outer walls of the multiple rollers are in contact with the lower inner surface of the two guide grooves 2 respectively. When the basket support plate moves, the rollers on its inner side roll within the second guide groove. The contact between the rollers and the second guide groove restricts the vertical movement and lateral offset of the basket support plate, while converting sliding friction into rolling friction, reducing movement resistance. The rolling trajectory of the rollers along the second guide groove and the guiding action of the guide rod form a double constraint, ensuring that the basket support plate drives the basket body to move in a straight line. Meanwhile, the groove wall of the second guide groove prevents the rollers from excessively offsetting, avoiding swaying when the basket body moves. This not only reduces movement friction loss but also further improves the stability of the basket body during movement. At the same time, the low resistance characteristics of rolling friction make the movement smoother, enhance the overall anti-sway capability, and allow the basket body to maintain a stable posture during movement. Storage boxes are fixedly connected to the upper surface of the hanging basket support plate and on both sides of the dual-axis motor support frame. Inclined plates are fixedly connected to the upper surface of the inner wall of the dual-axis motor support frame and on the left and right sides of the dual-axis motor. Multiple connecting pipes are provided on the lower side of the opposite side of the two inclined plates. Multiple through-flow holes are opened on the lower surface of the inner wall of the multiple connecting pipes. Conveying pipes are fixedly connected to the opposite sides of the two inclined plates. The opposite ends of the two conveying pipes extend into the interior of the two storage boxes respectively. When the dual-axis motor is working, the inclined plate moves synchronously with the dual-axis motor support frame. At this time, the liquid pumps on the outside of the two storage tanks can be periodically activated, allowing the internal lubricating oil from the two storage tanks to drip through the flow holes of the connecting pipe to the meshing point of the transmission gear and the gear belt, achieving dynamic lubrication. This automatically covers the meshing parts, avoiding the problem of omissions caused by manual lubrication, while also reducing gear wear and improving the durability and stability of the transmission system. Each of the two storage tanks has a liquid level display window on its opposite side, and both storage tanks have a filling port on their upper surface. When the oil level indicator shows insufficient oil, open the filler port to inject lubricating oil. The lubricating oil enters the storage tank through the filter screen and flows to the inclined plate through the delivery pipe to replenish the loss of the lubrication circulation system, ensuring continuous lubrication of the transmission gear and gear belt, and avoiding damage to the gears due to dry friction caused by lack of oil. A control box is fixedly connected to the upper surface of the dual-axis motor support frame. A second movable plate is symmetrically slidably connected inside the control box. A stop bar is fixedly connected to the inner side wall of the control box and to the opposite side of the two second movable plates. The top of the output shaft of the dual-axis motor extends into the inside of the control box and is fixedly connected to a rotating rod. A protrusion is symmetrically fixedly connected to the outer side wall of the rotating rod. A connecting box is fixedly connected to the left side of the two inclined plates. A second transmission gear is fixedly connected to the outer side wall of multiple connecting pipes. A first movable plate is slidably connected inside the two connecting boxes. A rack plate is fixedly connected to the right side of the two first movable plates. The lower surface of the two rack plates meshes with the outer side wall of multiple second transmission gears. Multiple return springs are fixedly connected to the front and rear surfaces of the control box, respectively, on the opposite sides of the two second movable plates. The inside of the control box is connected to the inside of the two control boxes. When the dual-axis motor starts, the rotating rod drives the two protrusions to rotate synchronously. As the two protrusions rotate to a specific angle, their outward convex parts press against the two movable plates, overcoming the spring force of the return spring and causing them to slide outward. The pushing of the movable plates pulls the two movable plates to slide to both sides, which in turn drives the two rack plates to translate. The multiple transmission gears meshing with the rack plates then rotate, thereby driving the connecting pipe to change its angle around a fixed point. By adjusting the tilt angle of the connecting pipe, lubricating oil can be precisely dripped onto different contact points between the transmission gears and the toothed belt, especially in areas prone to wear. Compared to dripping at a fixed angle, the lubricating oil coverage is wider and more uniform. When the protrusions lose contact with the movable plates, the return spring pushes the movable plates to reset, and the connecting pipe returns to its initial position. The direction and position of the lubricating oil dripping can then be dynamically adjusted according to the actual working conditions of the gear transmission, improving the targeting and efficiency of lubrication, effectively reducing gear wear, and further extending the service life of the transmission components. The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
