[0002] Under the background of continuous upgrading of infrastructure construction in China, as an important construction equipment in the field of bridge construction, the technology of cantilever construction hanging basket is undergoing a profound transformation from traditional mechanical type to intelligent and digital direction. The generation of hanging basket equipment has gradually broken through the limitations of traditional fulcrum structure and evolved towards automatic control and precise operation. The traditional hanging basket system generally has the technical bottlenecks of out-of-sync operation, insufficient adjustment accuracy and low intelligent level during construction, which not only affects the construction efficiency, but also challenges the engineering quality control. Therefore, promoting the development of bridge construction equipment towards intelligent and automatic direction has become an important research topic in the field of current engineering construction, and is also a key breakthrough for realizing construction process innovation.

[0003] In the current cantilever bridge construction practice, the adjustment operation of the hanging basket sling still mainly relies on the traditional way of manual operation of the jack. This operation mode requires high technical proficiency of the operator, and is prone to adjustment errors due to human factors, thereby affecting the overall construction accuracy. Due to the lack of effective automatic control means, the whole adjustment process not only consumes time and effort, but also is difficult to ensure the synchronization and coordination between the lifting points. This inefficient operation mode not only increases the construction cost and prolongs the construction period, but also restricts the overall progress of the project to some extent. Therefore, it is necessary to provide a vertical adjustment device for a hanging basket sling of a bridge cantilever construction, which can solve the problem of insufficient adjustment accuracy and low efficiency caused by the dependence on manual operation in the adjustment operation of the hanging basket sling in the prior art.

The top plate and the bottom plate of the adjusting master control platform 3 are correspondingly holed at the positions corresponding to the sling 7, and the holed size is greater than the cross-sectional size of the sling 7 and the pawl 8, so as to facilitate the movable penetration of the sling 7.

[0035] Please refer to the drawings Figure 2 , the drawings Figure 5 and the drawings Figure 6The adjusting control assembly comprises adjustable vertical rods 4, a horizontal rod 5, telescopic adjusting mechanisms 6, driving platforms 10, driving controllers 19, concentric rotating shafts 20 and driving gears 21.

One pair of driving controllers 19 is correspondingly arranged on the pair of driving platforms 10. One pair of driving gears 21 is coaxially arranged on the output shafts of the pair of driving controllers 19 through the concentric rotating shafts 20. The sling 7 is in the shape of a long strip with a rectangular cross section. The clamping teeth 8 are uniformly arranged on the two side surfaces of the short shaft of the sling 7. The sling 7 is in meshing transmission connection with the pair of driving gears 21 through the clamping teeth 8.

The temporary locking assembly is connected with the horizontal rod 5.

[0036] Preferably, the driving controller 19 can adopt the motor with bidirectional rotating function in the prior art. The model and specification of the motor can be adaptively selected according to the actual use requirement. The driving controller 19 is used for driving the concentric rotating shaft 20 to rotate. The concentric rotating shaft 20 drives the driving gear 21 to synchronously rotate, and the clamping teeth 8 are in meshing transmission through the driving gear 21.

[0037] The size and distribution interval of the clamping teeth 8 on the sling 7 are matched with the size and interval of the tooth groove of the driving gear 21, so as to ensure that the driving gear 21 can mesh and transmit the clamping teeth 8 when rotating, and realize the up and down movement control of the sling 7.

[0038] The adjustable vertical rod 4 is fixedly installed on the upper surface of the driving platform 10 and is perpendicular to the upper surface. The middle part of the adjustable vertical rod 4 is the telescopic adjusting mechanism 6, such as a spring rod, a corrugated telescopic rod or the like, which can realize the stretching or recovery of the adjustable vertical rod 4. The top end of the adjustable vertical rod 4 is fixedly connected with the lower surface of the top plate of the adjusting master control platform 3. The horizontal rod 5 is vertically fixedly installed at a position about 10 cm below the top end of the pair of adjustable vertical rods 4, which is used for connecting the pair of adjustable vertical rods 4 into a synchronous telescopic whole and connecting with the temporary locking assembly.

[0039] Please refer to the accompanying drawings Figure 2 to the accompanying drawings Figure 4The temporary locking assembly on the two sides of the short shaft of the sling 7 is symmetrically arranged, each temporary locking assembly comprises a clamping plate 11, a screw rod 12, a right-handed screw nut 13, a left-handed screw nut 14, a rotary control motor 15, a rotating shaft 16, a limiting connection support rod 17 and a connecting plate 18; a pair of clamping plates 11 are arranged on the outer sides of the two faces of the short shaft of the sling 7, one of the clamping plates 11 is connected with the horizontal rod 5 through the connecting plate 18 away from one face of the sling 7; the rotary control motor 15 is installed on one of the clamping plates 11 away from one face of the sling 7 through a plurality of limiting connection support rods 17, one end of the screw rod 12 is coaxially fixedly connected with the output shaft of the rotary control motor 15, and the other end of the screw rod 12 penetrates through the holes (not shown in the figure) in the pair of clamping plates 11 and is located on the side of the sling 7; the right-handed screw nut 13 is installed on one of the clamping plates 11 away from one face of the sling 7 and is matched and screwed on the screw rod 12, and the left-handed screw nut 14 is installed on the other clamping plate 11 away from one face of the sling 7 and is matched and screwed on the screw rod 12.

[0040] Preferably, the clamping plate 11 is provided with a hole, the size of the hole is slightly larger than the cross-sectional dimension of the screw rod 12, the vertical penetration of the screw rod 12 is facilitated, and the rotation of the screw rod 12 is not affected.

[0041] Preferably, the rotary control motor 15 can adopt the motor with a bidirectional rotation function in the prior art, and the specification and model of the motor can be adaptively selected according to actual use requirements. The rotary control motor 15 is used to drive the screw rod 12 to rotate. The rotary control motor 15 is fixed and limited between one of the clamping plates 11 through a plurality of limiting connection support rods 17, so that the rotary control motor 15 does not run away and twist when performing the rotation operation under the driving of the reaction force of the screw rod 12.

[0042] When the rotary control motor 15 receives the instruction of the main control module 40 to perform counterclockwise rotation, the screw rod 12 is driven to rotate counterclockwise synchronously; the screw rod 12 does not move radially or axially, and under the transmission of the screw thread, the right-handed screw nut 13 defaults to perform clockwise operation, so that the clamping plate 11 connected with the right-handed screw nut 13 moves close to one face of the sling 7; similarly, the left-handed screw nut 14 is symmetrically installed with the right-handed screw nut 13, and the left-handed screw nut 14 defaults to perform counterclockwise operation, so that the clamping plate 11 connected with the left-handed screw nut 14 moves close to the other face of the sling 7, and finally the temporary clamping and locking of the sling 7 is realized through the pair of clamping plates 11.

When temporarily locked, the sling 7 is always in a vertical state and cannot deviate laterally. At this time, when the driving controller 19 performs a rotating operation, the driving gear 21 is driven to rotate, and the sling 7 is correspondingly driven to move up and down. The sling 7 is locked between the pair of driving platforms 10 by the temporary locking assembly. When the sling 7 moves up and down, the telescopic adjusting mechanism 6 in the middle of the adjustable vertical rod 4 is driven to perform a telescopic adjusting action.

The bottom form measuring module 41 is arranged on the bottom form plate 45.

[0046] Preferably, the encoder 38 can be a roller type encoder. The roller of the encoder 38 is tightly attached to the sling 7. When the sling 7 moves up and down, the roller of the encoder 38 is driven to roll on the surface of the sling 7 by friction. The up and down movement distance of the sling 7 can be obtained by converting the rolling number of the roller of the encoder 38. The encoder 38 feeds back the calculated movement distance to the master control module 40.

[0047] Preferably, the master control module 40 can be a microcomputer control module in the prior art. After receiving the movement distance, the master control module 40 issues an auxiliary support instruction to the auxiliary support assembly.

[0060] Please refer to the attached Figure 7 to the attached Figure 9, the main control module 40 according to the information feedback of the measuring assembly, conversion of the height of the hole 9 of the sling 7 in the adjustment main control platform 3, and issues vertical adjustment instruction (i.e. auxiliary support instruction) to the first oil cylinder adjustment controller 25, and the first oil cylinder adjustment controller 25 receives the instruction and commands the first execution oil cylinder 23 to execute corresponding operation, further drives the adjustment fixed platform 26 to reach corresponding height, and feeds back the result to the main control module 40. The main control module 40 receives the feedback information and issues horizontal stretching instruction (i.e. auxiliary support instruction) to the second oil cylinder adjustment controller 29, and the second oil cylinder adjustment controller 29 receives the instruction and commands the second execution oil cylinder 27 to execute corresponding operation, further drives the pin shaft 39 to stretch outward until the pin shaft 39 passes through the corresponding hole 9 of the sling 7, and feeds back the result to the main control module 40. When the pin shaft 39 passes through the hole 9 of the sling 7, and the main control module 40 receives the feedback information, issues vertical adjustment auxiliary support instruction (i.e. auxiliary support instruction) to the third oil cylinder controller 33 and the fourth oil cylinder controller 37, and the third oil cylinder controller 33 and the fourth oil cylinder controller 37 receive the instruction and command the third execution oil cylinder 30 and the fourth execution oil cylinder 34 to execute corresponding operation, further drives the middle support block 32 and the end support block 36 to slowly rise until the middle and end of the pin shaft 39 are stopped, finally provides temporary support for the sling 7, reduces the tension of the bottom formwork 45 of the hanging basket body on the adjustment control assembly, reduces the local stress state of the whole device, and realizes the overall stress effect of the device.

[0061] Preferably, the signal transmission among the adjustment control assembly, the temporary locking assembly, the measuring assembly and the auxiliary support assembly can adopt wireless network transmission.

[0062] Please refer to the accompanying drawings Figure 1 , the hanging basket body includes hanging basket truss longitudinal beam 1, front upper cross beam 2, front lower cross beam 43 and bottom longitudinal beam 44; one end of the hanging basket truss longitudinal beam 1 is installed on the upper structure of the bridge 42, the other end of the hanging basket truss longitudinal beam 1 overhangs to the outside of the bridge 42, a plurality of hanging basket truss longitudinal beams 1 are arranged at intervals and connected into a whole through the front upper cross beam 2, and the adjustment main control platform 3 is installed on the front upper cross beam 2; one end of the bottom longitudinal beam 44 is installed on the lower structure of the bridge 42, the other end of the bottom longitudinal beam 44 overhangs to the outside of the bridge 42, a plurality of bottom longitudinal beams 44 are arranged at intervals and connected into a whole through the front lower cross beam 43; the sling 7 vertically penetrates the front upper cross beam 2, and the lower end of the sling 7 is connected and fixed with the front lower cross beam 43.

[0063] Preferably, the position corresponding to the sling 7 on the front upper cross beam 2 is designed as a hole penetrating up and down, and the size of the hole is slightly larger than the cross-sectional size of the sling 7 and the tooth 8, so as to facilitate the penetration of the sling 7.

[0064] Please refer to the accompanying drawings Figure 1 to the accompanying drawings Figure 10The working process and working principle of the present application are as follows:

[0065] 1. Before the vertical adjustment operation starts, the lifting belts 7 are in the locked state during the construction of the previous section. After the adjustment starts, the initial state of the vertical adjustment is set by default, and the adjustment fixed platform 26 is kept in the same vertical height as a certain lifting belt hole 9 (hereinafter referred to as "initial hole 9") of the lifting belt 7.

[0066] 2. The main control module 40 sends a tightening instruction to the rotation control motor 15. When the rotation control motor 15 receives the instruction from the main control module 40 to execute counterclockwise rotation, the screw rod 12 is driven to execute counterclockwise rotation. Under the transmission of the screw thread, the right-handed screw nut 13 executes clockwise operation by default, and the corresponding clamping plate 11 is pressed towards the lifting belt 7. Similarly, the left-handed screw nut 14 is symmetrically installed with the right-handed screw nut 13, and executes counterclockwise operation by default, and the corresponding clamping plate 11 is pressed towards the lifting belt 7, finally realizing the temporary locking between the pair of clamping plates 11 and the lifting belt 7. After the tightening is completed, the rotation control motor 15 feeds back the tightening completion information to the main control module 40.

[0067] 3. After the bottom mold plate 45 is measured by the bottom mold measurement module 41, the data is fed back to the main controller 40. After receiving the data, the main controller 40 identifies and analyzes whether the vertical adjustment of the bottom mold plate 45 is needed by comparing with the theoretical value. If adjustment is needed, the vertical adjustment displacement value is converted with the parameters such as the gear teeth and gear grooves of the drive gear 21, to obtain the number of rotation and the rotation direction (clockwise / counterclockwise) of the drive gear 21, and the number and direction are sent to the drive controller 19. The drive controller 19 receives the instruction and executes the corresponding adjustment operation, thereby driving the up and down adjustment of the lifting belt 7, and further realizing the vertical adjustment of the bottom mold plate 45. It should be noted that the corresponding drive controllers 19 on both sides of the side edge of the lifting belt 7 execute reverse rotation operation at the same time (i.e. when one drive controller 19 controls the drive gear 21 to execute clockwise operation, the other drive controller 19 controls the drive gear 21 to execute counterclockwise operation).

[0068] Suppose the up and down adjustment distance of the lifting belt 7 is S, the circumference of the drive gear 21 is L when it rotates one round, and the number of rotation of the drive gear 21 is F, then F=S / L is obtained through conversion.

[0069] 4. Before the vertical adjustment of the sling 7 begins, the encoder 38 measures the initial value and feeds it back to the main controller 40. During the adjustment process, the encoder 38 monitors the relative distance change (i.e., the travel distance of the sling 7) in real time through the rolling of the rollers and feeds it back to the main controller 40. After receiving the relative distance change data, the main controller 40 compares it with the adjustment displacement value to determine whether further adjustment is needed. If so, it sends the corresponding command to the drive controller 19 until the relative distance change matches the adjustment displacement value, that is, the vertical adjustment of the bottom template 45 or the sling 7 is completed.

[0070] 5. After the vertical adjustment of the sling 7 is completed, the vertical adjustment of the auxiliary support components is performed. Based on the information fed back from the measuring components, the main control module 40 calculates the height of the initial hole 9 on the sling 7 inside the main control platform 3 and issues a vertical adjustment distance command to the first hydraulic cylinder adjustment controller 25. Upon receiving the command, the first hydraulic cylinder adjustment controller 25 directs the first actuator cylinder 23 to perform the corresponding operation, further driving the adjustment fixing platform 26 to the corresponding height of the initial hole 9, and feeding the result back to the main control module 40. Upon receiving the feedback information, the main control module 40 issues a lateral stretching command to the second hydraulic cylinder adjustment controller 29. Upon receiving the command, the second hydraulic cylinder adjustment controller 29 directs the second actuator cylinder 27 to perform the corresponding operation, further driving the pin 39 to stretch outwards until it passes through the initial hole 9 of the sling 7, and feeding the result back to the main control module 40. After the pin 39 engages with the initial hole 9 on the sling 7, and the main control module 40 receives feedback information, it issues a vertical adjustment auxiliary support command to the third cylinder controller 33 and the fourth cylinder controller 37. Upon receiving the command, the third cylinder controller 33 and the fourth cylinder controller 37 instruct the third actuator cylinder 30 and the fourth actuator cylinder 34 to perform corresponding operations, further driving the middle support block 32 and the end support block 36 to slowly rise until they stop against the pin 39. This provides temporary support for the sling 7, reduces the tension on the bottom template 45 of the hanging basket body from the adjustment control component, reduces the local stress state of the entire device, and achieves the overall stress effect of the device, thereby ensuring the safe and controllable adjustment of the sling 7 and the bottom template 45.

Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
