Description

Technical Field

[0001] This utility model relates to the field of bridge construction equipment technology, and in particular to a pile-beam integrated machine for full-width construction. Background Technology

[0002] In the field of prefabricated bridge construction, the integrated pile-beam bridge erecting machine, as a highly efficient integrated device, enables coordinated operation of pier pile foundation construction and superstructure erection, significantly improving construction efficiency. Currently, the mainstream construction method for this type of equipment is the "half-width advancement, lateral movement" mode, which involves first completing the construction of the entire pile foundation and beam erection of a single bridge span, and then moving the entire equipment to an adjacent bridge span via a lateral sliding system to carry out construction on the other span. However, this operation mode has several inherent defects. First, construction efficiency needs further improvement. Each lateral movement of the equipment is cumbersome, requiring a large amount of auxiliary preparation work such as equipment leveling, outrigger conversion, and track laying. This process is time-consuming, and frequent movements consume a significant amount of effective working time, hindering breakthroughs in overall work efficiency. Second, there are certain safety and quality risks. Large equipment performing heavy-load lateral movement on a completed bridge deck places extremely high demands on the local bearing capacity and stability of the bridge deck structure, easily leading to structural damage. Meanwhile, the relocation process is affected by factors such as wind load and the synchronization of the hydraulic system, posing a risk of equipment jamming or even overturning, resulting in significant safety hazards. Furthermore, the applicability of this mode is limited. Its operational logic requires the piers to have sufficient width to accommodate the equipment legs and lateral movement space, making it less adaptable to narrow piers or bridge types with special structural forms, thus limiting its application scope. Utility Model Content

[0003] The purpose of this utility model is to overcome the technical problems of low construction efficiency, low safety and poor applicability caused by the existing integrated pile and beam bridge erection machine that can only be used for half-width construction, and to provide an integrated pile and beam machine for full-width construction.

[0004] This utility model provides an integrated pile-beam machine for full-width construction, including a main beam unit, a leg unit, a hoisting unit, and a pile driving unit. The main beam unit includes two main beams and two connecting beams. The two connecting beams are located at the beginning and end of the main beams and connect the two main beams. The length of the connecting beams is greater than the width of the bridge. The hoisting unit is located between the two main beams. The leg unit is installed at the bottom of the main beams. The pile driving unit is located on the main beams and near the end of the main beams facing the bridge construction direction.

[0005] Compared to existing integrated pile-beam machines or bridge erecting machines that can only perform half-width construction and then move the entire machine laterally via a transverse track under the main beam to complete the other half of the construction, resulting in low construction efficiency, this utility model adopts a frame main beam unit structure composed of two main beams and transverse connecting beams. The length of the connecting beams can be greater than the width of the bridge, meaning the distance between the two main beams is greater than the width of the bridge. This allows the integrated pile-beam machine to achieve complete coverage of the bridge in the width direction. During construction, a crane installed between the two main beams can be used to move laterally between the two main beams to lift and lay the beams, achieving one-time full-width construction of the bridge in the width direction without the need for the entire machine to move laterally, thus improving construction efficiency.

[0006] Preferably, the support leg unit includes a temporary support leg, a front auxiliary support leg, a front support leg, a middle support leg, a rear support leg, and a rear auxiliary support leg arranged sequentially along the main beam. The lower end of the temporary support leg is provided with a toothed structure. A support truss connects the two middle support legs corresponding to the two main beams.

[0007] Compared to traditional bridge erecting machines, the integrated piling and beam machine adds a piling unit to the side of the main beam facing the construction direction, shifting the machine's center of gravity forward. If only the legs in the middle of the main beam are used for support, the front end of the main beam, where the piling unit is located, will form a cantilever end. In addition, the load applied to the main beam by the piling unit will pose a risk of the main beam tipping forward. Therefore, a set of temporary outriggers needs to be added to the front end of the main beam to support it on the ground as a support structure for the cantilever end of the main beam. In addition, for some special construction sites, such as soft foundations like sandy soil, the hoisting and piling units on the main beam will usually move laterally and longitudinally during construction, causing the center of gravity of the integrated machine to change and generating horizontal stress. The temporary outriggers need to have good support and grip performance. Therefore, a toothed structure is set at the lower end of the temporary outriggers, which can provide support force while offsetting horizontal stress, thus improving support and grip performance.

[0008] Preferably, it also includes a pile cap unit, which comprises a plurality of pile caps, the pile caps being able to be installed on top of the bridge pile and supported at the bottom of the outrigger unit.

[0009] For the outrigger units, such as the front auxiliary outrigger, front outrigger, and middle outrigger, during the operation of the integrated machine, they need to be supported on the bridge piles that have been driven into the ground. In order to protect the bridge pile structure and avoid the outriggers sitting directly on the bridge piles, which may easily cause damage to the concrete structure of the bridge piles, it is necessary to first put a pile cap on the pile head for protection, and then sit the outriggers on the pile cap to support the integrated machine.

[0010] Preferably, a sinking groove is provided at the center of the top of the pile cap, and a lifting lug is installed at the bottom of the sinking groove. The depth of the sinking groove is greater than or equal to the height of the lifting lug.

[0011] During the through-hole operation of the integrated hoist, after the current outrigger moves one span forward from the current pier to the next pier, the pier cap at the top of the departed pier needs to be hoisted to the rear bridge deck for later use. The existing hoisting method involves setting multiple lifting points on the side of the pier cap and using a crane on the main beam to lower steel wire ropes to lift the pier cap from these points. However, during the hoisting of the pier cap to the rear bridge deck, it needs to pass through the support truss of the middle outrigger. This hoisting method limits the height at which the pier cap can be lifted; the height of the bottom of the pier cap at the highest point of hoisting will still be lower than the top of the support truss. Therefore, the support truss will interfere with the pier cap and cause a collision. In other words, the hoisted pier cap has no... The pile cap is hoisted over the supporting truss to the rear bridge deck. Therefore, improvements to the hoisting structure are necessary. This invention reduces the hoisting point of the pile cap to one, placing it at the center of the top of the pile cap. This ensures the hoisting point coincides with the center of gravity of the pile cap, guaranteeing its stable horizontal position after hoisting. This avoids the pile cap deflecting due to a single hoisting point. Furthermore, the use of a sinking trough structure with the lifting lugs positioned within it reduces the distance between the pile cap and the crane when hoisted to the highest point. This raises the bottom of the pile cap above the top of the supporting truss, ensuring the pile cap passes over the supporting truss of the middle outrigger during hoisting to the rear bridge deck, preventing interference and collisions.

[0012] Preferably, the top of the pile cap and / or the lower part of the toothed structure are provided with a heightening section.

[0013] Because some construction projects use precast concrete bridge piles in single sections, which are made into full-size structures during prefabrication, pile driving can be carried out directly on the construction site without splicing. However, the existing integrated machine is only suitable for segmented bridge piles. For precast whole-section bridge piles, the machine height is insufficient, resulting in the pile driving platform lifting height being lower than the bridge pile height, making it impossible to erect the pile. Therefore, this utility model requires the addition of heightening sections at the bottom of each leg. The heightening sections are specifically located at the bottom of the toothed structure of the temporary leg and the top of the pile cap, which can increase the overall height of the integrated machine and ensure that the lifting height of the pile driving platform is higher than the bridge pile height, thereby enabling the erection of whole-section bridge piles.

[0014] Preferably, anti-roller sets are provided between the front auxiliary leg, the front support leg, the middle support leg, and the rear support leg and the main beam.

[0015] During the operation of the integrated machine, the movement of each support leg relative to the main beam and the overall forward movement of the main beam are all driven by the anti-roller assembly. Specifically, when the front auxiliary support leg, front support leg, middle support leg and rear support leg are in the supported state, the temporary support leg and rear auxiliary support leg are lifted, and the main beam can be driven to move forward as a whole through the anti-roller assembly. When only one or more of the front auxiliary support leg, front support leg, middle support leg and rear support leg are lifted, and the other support legs are kept supported, the lifted support leg can also be driven to move forward through the anti-roller assembly, while the main beam remains fixed.

[0016] Preferably, a pedestrian walkway is installed along the upper edge of the main beam, and several spaced uprights are provided on both sides of the pedestrian walkway, with fall protection safety ropes connecting adjacent uprights.

[0017] During the pile driving operation, construction workers need to work at height on the main beam machine's pile driving platform. The main beam is equipped with a pedestrian walkway. To ensure the safety of construction workers working at height, guardrails and fall protection ropes can be installed on both sides of the pedestrian walkway. The fall protection ropes can be fixedly connected to the vertically installed poles. Construction workers can attach their safety rope hooks to the fall protection ropes, which can enhance the safety of working at height.

[0018] Preferably, the hoisting unit includes several cranes, and a slide rail is provided between the crane and the main beam.

[0019] Multiple cranes are usually installed between the main beams on both sides. For example, three cranes can be installed, specifically including two 16T pile-lifting cranes and one 80T crane trolley. Each crane has a slide rail at the connection point between its two sides and the main beam. The slide rail is set along the length of the main beam, and the crane can slide on the main beam along the slide rail under the drive of the motor.

[0020] Preferably, the piling unit includes a transverse platform and a longitudinal platform. A pile-lifting winch is provided on the transverse platform. Guide rollers are provided on the edge of the transverse platform below the pile-lifting winch, and the steel wire rope lowered by the pile-lifting winch can pass around the guide rollers.

[0021] The piling unit's transverse platform is equipped with a pile-lifting winch. The winch can be connected to the horizontally placed bridge piles on the ground via a steel wire rope. Lifting the steel wire rope can raise the horizontal bridge piles to a vertical position, thus erecting the piles and preparing for subsequent piling operations. However, the steel wire rope being lowered and lowered from the winch will rub against the edge of the transverse platform, causing wear and tear over time and affecting the safety of the piling operation. Therefore, this invention can install guide rollers at the edge of the transverse platform where the steel wire rope passes. The steel wire rope can bypass the guide rollers and drive the guide rollers to rotate during lifting and lowering, which can reduce the friction of the steel wire rope, avoid wear on the steel wire rope, and improve operational safety.

[0022] Preferably, the piling unit further includes a pile hammer winch installed above the main beam, and the pile hammer winch is connected to the pile hammer of the piling unit via a steel wire rope.

[0023] The pile hammer winch is fixedly installed on the main beam and does not move with the horizontal and vertical platforms of the pile driving unit. During pile driving, the pile hammer is moved up and down by raising or lowering the steel wire rope through the pile hammer winch, thereby hammering the top of the bridge pile and driving the bridge pile into the ground to complete the pile driving operation.

[0024] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention provides a pile-beam integrated machine for full-width construction. Compared to existing pile-beam integrated machines or bridge erecting machines that can only perform half-width construction and then move the entire machine laterally via a transverse track under the main beam to complete the other half of the construction, resulting in low construction efficiency, this invention uses a frame main beam unit structure composed of two main beams and transverse connecting beams. The length of the connecting beams can be greater than the width of the bridge, meaning the distance between the two main beams is greater than the width of the bridge. This allows the pile-beam integrated machine to achieve full coverage of the bridge in the width direction. During construction, a crane installed between the two main beams can be used to move laterally between the two main beams to lift and lay the beams, achieving one-time full-width construction of the bridge in the width direction without the need for the entire machine to move laterally, thus improving construction efficiency.

[0040] Example This embodiment provides a pile-beam integrated machine for full-width construction.

[0041] like Figures 1 to 8 As shown in the figure, the integrated pile-beam machine for full-width construction in this embodiment includes a main beam unit 11, a leg unit 2, a hoisting unit 6, and a pile driving unit 7. The main beam unit 11 includes two main beams 11 and two connecting beams 12. The two connecting beams 12 are located at the beginning and end of the main beams 11 and are connected between the two main beams 11. The length of the connecting beams 12 is greater than the width of the bridge. The hoisting unit 6 is set between the two main beams 11. The leg unit 2 is installed at the bottom of the main beams 11. The pile driving unit 7 is set on the main beams 11 and close to the end of the main beams 11 facing the bridge construction direction.

[0042] Compared to existing integrated pile-beam machines or bridge erecting machines that can only perform half-width construction and then move the entire machine laterally via the transverse track under the main beam 11 before proceeding to the other half, resulting in low construction efficiency, this utility model adopts a frame main beam 11 unit structure composed of two main beams 11 and transverse connecting beams 12. The length of the connecting beams 12 can be greater than the width of the bridge, meaning the distance between the two main beams 11 is greater than the width of the bridge. This allows the integrated pile-beam machine to achieve full coverage of the bridge in the width direction. During construction, the crane installed in the hoisting unit 6 between the two main beams 11 can be used to move laterally between the two main beams 11 to hoist and lay the beams. This allows for one-time full-width construction of the bridge in the width direction without the need for the entire machine to move laterally, thus improving construction efficiency.

[0043] In this embodiment, the support leg unit 2 includes a temporary support leg 21, a front auxiliary support leg 22, a front support leg 23, a middle support leg 24, a rear support leg 25, and a rear auxiliary support leg 26 arranged sequentially along the main beam 11. The lower end of the temporary support leg 21 is provided with a toothed structure 211. A support truss 241 is connected between the two middle support legs 24 corresponding to the two main beams 11.

[0044] Compared to traditional bridge erecting machines, the integrated piling and beam machine adds a piling unit 7 to the side of the main beam 11 facing the construction direction, causing the center of gravity of the entire machine to shift forward. If only the legs in the middle section of the main beam 11 are used for support, the front end of the main beam 11, that is, the end where the piling unit 7 is located, will form a cantilever end. In addition, the load applied to the main beam 11 by the piling unit 7 will pose a risk of the main beam 11 overturning forward. Therefore, a set of temporary legs 21 needs to be added to the front end of the main beam 11 to support it on the ground as a support structure for the cantilever end of the main beam 11. In addition, for some special construction project sites, such as soft foundations such as sandy soil, the hoisting unit 6 and piling unit 7 on the main beam 11 will usually move laterally and longitudinally during construction operations, which will cause the center of gravity of the integrated machine to change and generate horizontal stress. The temporary legs 21 need to have good support and grip performance. Therefore, a toothed structure 211 is set at the lower end of the temporary legs 21, which can provide support force while offsetting horizontal stress, thus improving support and grip performance.

[0045] In this embodiment, a pile cap 3 unit is also included. The pile cap 3 unit includes a plurality of pile caps 3, which can be installed on the top of the bridge pile 8 and supported on the bottom of the outrigger unit 2.

[0046] For the outrigger unit 2, specifically the front auxiliary outrigger 22, the front outrigger 23 and the middle outrigger 24, during the operation of the integrated machine, it needs to be supported on the bridge piles 8 that have been driven into the ground. In order to protect the structure of the bridge piles 8 and avoid the outriggers sitting directly on the bridge piles 8, which may easily cause damage to the concrete structure of the bridge piles 8, it is necessary to first put the pile cap 3 on the pile head of the bridge pile 8 for protection, and then sit the outriggers on the pile cap 3 to support the integrated machine.

[0047] Optionally, a sinking groove 31 is provided at the center of the top of the pile cap 3, and a lifting lug 32 is installed at the bottom of the sinking groove 31. The depth of the sinking groove 31 is greater than or equal to the height of the lifting lug 32.

[0048] During the through-hole operation of the integrated machine, after the current support leg 23 moves one span forward from the current bridge pile 8 to the bridge pile 8 in front, the pile cap 3 on the top of the departed bridge pile 8 needs to be hoisted to the rear bridge deck for later use. The existing hoisting method is to set multiple lifting points on the side of the pile cap 3, and use the crane 61 on the main beam 11 to lower the wire rope 76 to lift the multiple lifting points on the side of the pile cap 3. However, during the process of hoisting the pile cap 3 to the rear bridge deck, it needs to pass through the support truss 241 of the middle support leg 24. The height that the pile cap 3 can be lifted using this hoisting method is limited. The height of the bottom of the pile cap 3 corresponding to the highest point of hoisting will still be lower than the height of the top of the support truss 241. Therefore, the support truss 241 will interfere with the pile cap 3 and cause a collision. In other words, the hoisted pile cap 3. Since it is impossible to lift the pile cap 3 over the supporting truss 241 to the rear bridge deck, the lifting structure needs to be improved. This utility model reduces the lifting point of the pile cap 3 to one and sets it at the center of the top of the pile cap 3, so that the lifting point position coincides with the center of gravity of the pile cap 3. This can ensure that the pile cap 3 can maintain a stable horizontal posture after being lifted, and avoid the pile cap 3 from deflection caused by lifting with a single lifting point. In addition, the structure of the sinking groove 31 is adopted, and the lifting lug 32 is set in the sinking groove 31. When the pile cap 3 is lifted to the highest point, the height of the pile cap 3 from the crane 61 can be reduced, and the bottom height of the pile cap 3 can be raised to be higher than the top height of the supporting truss 241. This ensures that the pile cap 3 can pass over the supporting truss 241 of the middle support leg 24 during the lifting to the rear bridge deck, avoiding interference and collision.

[0049] In this embodiment, the top of the pile cap 3 and / or the lower part of the toothed structure 211 are provided with a heightening section 4.

[0050] Because the bridge piles 8 used in some construction projects are single-segment precast concrete bridge piles 8, the bridge piles 8 are made into a whole-size structure during prefabrication, and can be directly driven on the construction site without splicing. However, the existing integrated machine is only suitable for segmented bridge piles 8. For precast whole-segment bridge piles 8, the height of the machine is insufficient when erecting the pile, resulting in the lifting height of the pile driving platform being lower than the height of the bridge pile 8, making it impossible to erect the pile. Therefore, this utility model needs to add a heightening section 4 at the bottom of each leg. The specific location of the heightening section 4 is at the bottom of the toothed structure 211 of the temporary leg 21 and the top of the pile cap 3, which can increase the overall height of the integrated machine and ensure that the lifting height of the pile driving platform is higher than the height of the bridge pile 8, thereby realizing the erection operation of the whole-segment bridge pile 8.

[0051] In this embodiment, anti-roller sets 5 are provided between the front auxiliary support leg 22, the front support leg 23, the middle support leg 24 and the rear support leg 25 and the main beam 11.

[0052] During the operation of the integrated machine, the movement of each support leg relative to the main beam 11 and the overall forward movement of the main beam 11 are all driven by the anti-roller group 5. Specifically, when the front auxiliary support leg 22, front support leg 23, middle support leg 24 and rear support leg 25 are in a supported state, the temporary support leg 21 and the rear auxiliary support leg 26 are lifted, and the main beam 11 can be driven to move forward as a whole by the anti-roller group 5. When only one or more of the front auxiliary support leg 22, front support leg 23, middle support leg 24 and rear support leg 25 are lifted, and the other support legs are kept supported, the lifted support leg can also be driven to move forward by the anti-roller group 5, while the main beam 11 remains fixed.

[0053] In this embodiment, a pedestrian walkway 111 is installed on the upper edge of the main beam 11. Several spaced uprights 112 are provided on both sides of the pedestrian walkway 111, and a fall protection safety rope 113 is connected between adjacent uprights 112.

[0054] During the pile driving operation, construction workers need to work at height on the pile driving platform of the main beam 11. The main beam 11 is equipped with a pedestrian walkway 111. To ensure the safety of construction workers working at height, guardrails and fall protection ropes 113 can be installed on both sides of the pedestrian walkway 111. The fall protection ropes 113 can be fixedly connected to the vertically installed uprights 112. Construction workers can hang their safety rope hooks on the fall protection ropes 113, which can enhance the safety of working at height.

[0055] In this embodiment, the hoisting unit 6 includes several cranes 61, and a slide rail 62 is provided between the cranes 61 and the main beam 11.

[0056] Multiple cranes 61 are usually installed between the main beams 11 on both sides. For example, three cranes 61 can be installed, specifically including two 16T pile-lifting cranes and one 80T crane trolley. Each crane has a slide rail 62 at the connection position between its two sides and the main beam 11. The slide rail 62 is set along the length of the main beam 11, and the crane can slide on the main beam 11 along the slide rail 62 under the drive of the motor.

[0057] In this embodiment, the piling unit 7 includes a transverse platform 71 and a longitudinal platform 72. A piling winch 73 is provided on the transverse platform 71. A guide roller 74 is provided on the edge of the transverse platform 71 below the piling winch 73. The steel wire rope 76 lowered by the piling winch 73 can pass around the guide roller 74.

[0058] The piling unit 7 has a piling winch 73 on its transverse platform 71. The piling winch 73 can be connected to the horizontally placed bridge piles 8 on the ground via a steel wire rope 76. By lifting the steel wire rope 76, the horizontal bridge piles 8 can be raised to a vertical position, thus achieving pile erection and preparing for subsequent piling operations. However, the steel wire rope 76 lowered from the piling winch 73 will rub against the edge of the transverse platform 71. Over time, this will cause wear on the steel wire rope 76, affecting the safety of the pile erection operation. Therefore, this invention can set a guide roller 74 at the edge of the transverse platform 71 where the steel wire rope 76 passes. The steel wire rope 76 can bypass the guide roller 74 and drive the guide roller 74 to rotate during the lifting and lowering process, which can reduce the friction of the steel wire rope 76, avoid wear on the steel wire rope 76, and improve the safety of the operation.

[0059] Alternatively, the piling unit 7 may also include a pile hammer winch 75 mounted above the main beam 11, the pile hammer winch 75 being connected to the pile hammer of the piling unit 7 via a wire rope 76.

[0060] The pile hammer winch 75 is fixedly installed on the main beam 11 and does not move with the transverse platform 71 and longitudinal platform 72 of the pile driving unit 7. During pile driving, the pile hammer is moved up and down by raising or lowering the steel wire rope 76 through the pile hammer winch 75, thereby hammering the top of the bridge pile 8 and driving the bridge pile 8 into the ground to complete the pile driving operation.

[0061] In summary, this utility model provides a pile-beam integrated machine for full-width construction. Compared to existing pile-beam integrated machines or bridge erecting machines that can only perform half-width construction and then move the entire machine laterally via the transverse track under the main beam to complete the other half of the construction, resulting in low construction efficiency, this utility model adopts a frame main beam unit structure composed of two main beams and transverse connecting beams. The length of the connecting beams can be greater than the width of the bridge, meaning the distance between the two main beams is greater than the width of the bridge. This allows the pile-beam integrated machine to achieve full coverage of the bridge in the width direction. During construction, a crane installed between the two main beams can be used to move laterally between the two main beams to lift and lay the beams, achieving one-time full-width construction of the bridge in the width direction without the need for the entire machine to move laterally, thus improving construction efficiency.

[0062] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
