Description

Technical Field

[0001] The invention belongs to the technical field of bridges, and in particular relates to a pier maintenance platform. Background Art

[0002] A bridge is a structure that crosses a river, strait, lake, canyon or other obstacle to allow vehicles and pedestrians to pass. It is not only an important part of transportation infrastructure, but also the crystallization of human wisdom and engineering technology. The construction of bridges has a long history, from simple wooden bridges and stone bridges in ancient times to modern steel bridges, concrete bridges, suspension bridges, cable-stayed bridges and other complex structures.

[0003] Bridges usually include piers. When building and repairing bridges, workers need to work outside the piers. In the prior art, workers usually reach the outer wall of the piers by rappelling with rigging. However, this is highly dangerous and inconvenient for workers to operate due to the limitations of rigging.

[0004] Therefore, there is an urgent need for a platform that is convenient for personnel to carry out construction or maintenance on the bridge pier. Summary of the invention

[0005] In view of the shortcomings existing in the related art, the present invention provides a bridge pier maintenance platform. Through two semi-circular walkways, the maintenance half platform can be conveniently used to form a closed circular maintenance platform around the bridge pier. Operators can move directly on the walkway to facilitate their construction or maintenance. This design not only improves the safety of maintenance operations and prevents the risk of workers falling from heights, but also greatly improves the convenience and efficiency of maintenance operations. The semi-circular design of the walkway enables the maintenance platform to fit tightly against the bridge pier, while the setting of the guardrail further ensures the safety of the workers. In addition, through the combination of multiple beams and hangers, the maintenance platform can be firmly erected on the bridge pier to ensure the stability and reliability of the maintenance operation. And there is no need to connect the two maintenance half platforms, which is convenient for installation and dismantling, so as to solve the technical problem of inconvenient maintenance or construction in the prior art.

[0006] The present invention provides a bridge pier maintenance platform, comprising:

[0007] Two maintenance half-stations, the maintenance half-stations comprising:

[0008] A walking path, wherein the walking path is arranged in a semi-circular shape;

[0009] A guardrail, the guardrail is arranged on the outer edge above the walkway and along the extending direction of the walkway;

[0010] A plurality of cross beams, the cross beams are used to be erected on the upper surface of the pier; and the plurality of cross beams are parallel to each other;

[0011] A plurality of suspension rods, the top ends of the suspension rods are connected to the ends of the cross beams, and the bottom ends of the suspension rods are connected to the walkway;

[0012] The installation steps are as follows: hoist the two maintenance half-platforms respectively, and set the walkway on the bridge pier, and erect the crossbeam on the upper surface of the bridge pier; the walkways in the two maintenance half-platforms are aligned with each other to form a closed ring.

[0013] In the technical solution, through two semi-circular walkways, the maintenance half-platform can be easily used to form a closed circular maintenance platform around the bridge pier. Operators can move directly on the walkway to facilitate their construction or maintenance. This design not only improves the safety of maintenance operations and prevents the risk of workers falling from heights, but also greatly improves the convenience and efficiency of maintenance operations. The semi-circular design of the walkway allows the maintenance platform to fit closely to the bridge pier, and the setting of the guardrail further ensures the safety of the workers. In addition, through the combination of multiple beams and hangers, the maintenance platform can be firmly erected on the bridge pier to ensure the stability and reliability of the maintenance operation. And there is no need to connect the two maintenance half-platforms, which is convenient for installation and dismantling.

[0014] In some embodiments, the suspension rod includes an upper connecting rod and a lower connecting rod, and a height adjustment device is arranged between the upper connecting rod and the lower connecting rod; the height adjustment device includes a screw rod, one end of which is rotatably connected to the lower connecting rod, and the other end is threadedly connected to the upper connecting rod.

[0015] In the technical solution, the height of the maintenance platform can be flexibly adjusted according to actual needs through the height adjustment device to adapt to bridge piers of different heights, and the height can be adjusted according to the needs of construction or maintenance. The screw in the height adjustment device is connected to the upper connecting rod through a thread, and the height can be adjusted by turning the screw, achieving precise height adjustment and improving the adaptability and flexibility of the maintenance platform.

[0016] In some embodiments, the height adjustment device further includes a turbine, a worm and a motor; the turbine is coaxially connected to the screw, the worm is meshed with the turbine, and the output shaft of the motor is connected to the worm.

[0017] In the technical solution, this design makes the height adjustment process more automated and labor-saving, and workers can adjust the height without manually rotating the screw. The introduction of the motor improves work efficiency, while the worm gear transmission mechanism ensures the stability and reliability of the transmission, further improving the user experience of the maintenance platform.

[0018] In some embodiments, a handle is connected to one end of the worm away from the motor, and the handle includes a sleeve rod connected to the worm, and an inner rod is slidably connected inside the sleeve rod.

[0019] The technical solution provides an alternative solution for manually adjusting the height. When the motor fails or needs fine-tuning, the worker can turn the handle to drive the worm to rotate, thereby adjusting the height of the maintenance platform. The sliding connection design of the sleeve rod and the inner rod of the handle allows the handle to be extended and retracted as needed. When the force is not enough, the inner rod can be moved away from the sleeve rod to increase the lever arm for easy manual operation.

[0020] In some embodiments, a suspension rope is provided in the upper suspension rod, one end of the suspension rope is connected to the upper connecting rod, and the other end of the suspension rope is connected to the screw rod;

[0021] A tension spring is arranged in the upper suspension rod, one end of the tension spring is connected to the upper connecting rod, and the other end is connected to the screw rod.

[0022] In the technical solution, when the screw rod is separated from the upper suspension rod, it can be pulled by the suspension rope to prevent the maintenance half platform from falling off as a whole. In addition, the tension spring can also provide a certain buffer force when the screw rod is loose, fails or falls off from the upper suspension rod, preventing the maintenance platform from falling suddenly, further improving the safety of maintenance operations.

[0023] In some embodiments, the thread direction of the screw is opposite to the helical direction of the tension spring.

[0024] In the technical solution, the higher the height of the top of the screw rod from the upper hanging rod, the greater the impact force received by the walkway when the screw rod is detached from the upper hanging rod, and thus the greater the risk of the hanging rope breaking; when the screw rod is screwed in the direction of the upper hanging rod, because its thread direction is opposite to the spiral direction of the tension spring, the tighter the tension spring is screwed, the greater the tension of the tension spring, and when the screw rod is detached from the upper hanging rod, the tension spring can better achieve cushioning, thereby further reducing the impact of falling and the risk of hanging rope breaking, thereby further improving the safety factor.

[0025] In some of the embodiments, between multiple beams in the same maintenance half-platform, a positioning rod is provided between any two adjacent beams.

[0026] In the technical solution, this design enhances the connection strength and stability between the beams. Any two adjacent beams are fixed by positioning rods, making the structure of the entire maintenance half platform more stable and less prone to deformation or displacement. This helps to ensure the stability and safety of the maintenance platform on the pier and improve the efficiency and quality of maintenance work. In addition, during lifting, displacement or offset between beams is avoided, making it easier to lift and install the pier maintenance platform.

[0027] In some embodiments, two crossbeams are provided in the same inspection half-platform, two mutually parallel positioning rods are provided between the two crossbeams, and a placement area is formed between the crossbeams and the positioning rods;

[0028] In the installation step, when the cross beam is erected on the upper surface of the pier, specifically: the support pad stone on the top of the pier is placed in the placement area.

[0029] In the technical solution, after installation, the support pedestal is located in the placement area. Even if shaking occurs, the beam and the positioning rod will abut the side wall of the corresponding support pedestal, thereby avoiding the possibility of displacement of the beam and the positioning rod, and further avoiding the possibility of the beam detaching from the pier, thereby improving the overall stability of the pier maintenance platform.

[0030] In some of the embodiments, a bottom support rod is provided below the walkway, and the suspension rod is connected to the bottom support rod.

[0031] In the technical solution, the design of the bottom support rod facilitates the connection of the boom and can disperse and transfer the load transmitted by the boom, making the structure of the entire maintenance platform more stable and reliable. At the same time, the setting of the bottom support rod also improves the wind resistance and earthquake resistance of the maintenance platform, ensuring the safety and stability of the maintenance work.

[0032] In some embodiments, the guardrail is 1.2 meters high and includes a railing and a plurality of vertical bars, and the vertical bars are spaced 1.5 meters apart.

[0033] In the technical solution, this design fully considers the safety and practicality of maintenance work. The 1.2-meter height and the reasonable setting of the vertical pole spacing can effectively prevent the risk of workers falling from heights.

[0034] Based on the above technical solution, in the embodiment of the present invention, through two semi-circular walkways, the maintenance half-platform can be conveniently used to form a closed circular maintenance platform around the bridge pier. Operators can move directly on the walkway to facilitate their construction or maintenance. This design not only improves the safety of maintenance operations and prevents the risk of workers falling from heights, but also greatly improves the convenience and efficiency of maintenance operations. The semi-circular design of the walkway enables the maintenance platform to fit closely to the bridge pier, and the setting of the guardrail further ensures the safety of the workers. In addition, through the combination of multiple beams and hangers, the maintenance platform can be firmly erected on the bridge pier to ensure the stability and reliability of the maintenance operation. And there is no need to connect the two maintenance half-platforms, which is convenient for installation and dismantling. BRIEF DESCRIPTION OF THE DRAWINGS

In an illustrative embodiment of the bridge pier maintenance platform of the present invention, the bridge pier maintenance platform includes: two maintenance half-platforms, the maintenance half-platform includes: a walkway 400, a guardrail 500, a plurality of beams 100 and a plurality of hangers 200; wherein the shape of the walkway 400 is semi-circular.

[0051] The guardrail 500 is disposed on the outer edge of the upper portion of the walkway 400 and is disposed along the extending direction of the walkway 400 .

[0052] The cross beam 100 is used to be erected on the upper surface of the pier; and a plurality of cross beams 100 are parallel to each other.

[0053] The top end of the suspension rod 200 is connected to the end of the beam 100 , and the bottom end of the suspension rod 200 is connected to the walkway 400 .

[0054] The installation steps of the pier maintenance platform are as follows: hoist the two maintenance half-platforms respectively, and set the walkway 400 on the pier, and set the beam 100 on the upper surface of the pier; the walkways 400 in the two maintenance half-platforms are aligned with each other to form a closed ring.

[0055] Through the above scheme, through two semi-circular walkways 400, it is possible to conveniently use the maintenance half-platform to form a closed circular maintenance platform around the bridge pier. Operators can move directly on the walkway 400 to facilitate their construction or maintenance. This design not only improves the safety of maintenance operations and prevents the risk of workers falling from heights, but also greatly improves the convenience and efficiency of maintenance operations. The semi-circular design of the walkway 400 allows the maintenance platform to fit closely to the bridge pier, and the provision of the guardrail 500 further ensures the safety of the workers. In addition, through the combination of multiple beams 100 and hangers 200, the maintenance platform can be firmly erected on the bridge pier to ensure the stability and reliability of the maintenance operation. And there is no need to connect the two maintenance half-platforms, which is convenient for installation and dismantling.

[0056] In some embodiments, the walkway 400 is arranged in a U-shape.

[0057] Furthermore, the walking path 400 includes two parallel sections and an arc section, the two parallel sections are parallel to each other and have the same length, and the ends of the two parallel sections are flush, and the two ends of the arc section are respectively connected to one end of the two parallel sections, thereby forming the walking path 400.

[0058] In some embodiments, the walking path 400 includes a keel frame and a walking board. The walking board is made of a 10 mm thick patterned steel plate. This design can increase the friction of the upper surface to prevent people from slipping and falling.

[0059] In other embodiments, the walking board may also be made of other materials such as wooden boards or steel boards.

[0060] In some embodiments, the walking board is disposed on the upper surface of the keel frame. The keel frame is in the shape of a U-shaped frame corresponding to the walking path 400.

[0061] In some embodiments, the keel frame is made of 75mm×5mm angle steel, which has high structural strength.

[0062] In some embodiments, the beam 100 is made of 16-gauge channel steel.

[0063] In some embodiments, the hanger 200 is made of No. 10 channel steel.

[0064] In some embodiments, an upper connecting plate is provided at the top of the suspension rod 200 , and an upper plug hole is opened on the upper connecting plate. The upper plug hole is used for plugging the cross beam 100 , so as to facilitate the connection between the cross beam 100 and the suspension rod 200 .

[0065] Furthermore, the upper connecting plate adopts a 5mm×50mm triangular limiting steel plate.

[0066] Furthermore, the cross beam 100 and the upper connecting plate may be connected by bolts.

[0067] In other embodiments, the cross beam 100 and the suspension rod 200 are directly connected by bolts.

[0068] In some embodiments, the suspension rod 200 is arranged in an inclined manner. The top end of the suspension rod 200 is close to the bridge pier, and the bottom end of the suspension rod 200 is inclined in a direction away from the bridge pier. In this way, a triangle is formed between the suspension rod 200 and the bridge pier, and the stability of the bridge pier maintenance platform on the bridge pier is improved by the principle that the triangle has stability.

[0069] In some embodiments, the suspension rod 200 includes an upper connecting rod 600 and a lower connecting rod 700, and a height adjustment device is provided between the upper connecting rod 600 and the lower connecting rod 700; the height adjustment device includes a screw rod 800, one end of which is rotatably connected to the lower connecting rod 700, and the other end is threadedly connected to the upper connecting rod 600. The height of the maintenance platform can be flexibly adjusted according to actual needs through the height adjustment device to adapt to bridge piers of different heights, and the height can be adjusted according to the needs of construction or maintenance. The screw rod 800 in the height adjustment device is threadedly connected to the upper connecting rod 600, and the height can be adjusted by rotating the screw rod 800, thereby achieving precise height adjustment and improving the adaptability and flexibility of the maintenance platform.

[0070] In some embodiments, the top of the upper link 600 is connected to the beam 100 , and the bottom of the lower link 700 is connected to the walkway 400 .

[0071] In some embodiments, the bottom end of the screw rod 800 passes through and is rotatably connected to the lower connecting rod 700 .

[0072] In some embodiments, a lower stopper is provided at one end of the screw rod 800 passing through the lower connecting rod 700, and the lower stopper is used to prevent the screw rod 800 from being separated from the lower connecting rod 700.

[0073] In some embodiments, the screw 800 passes through and is threadedly connected to the bottom end of the upper connecting rod 600. An upper limit stop is also provided at the top of the screw 800. The diameter of the upper limit stop is larger than the diameter of the screw 800 to prevent the top of the screw 800 from detaching from the upper connecting rod 600.

[0074] In some embodiments, the height adjustment device further includes a turbine 900, a worm 110 and a motor 120; the turbine 900 is coaxially connected to the screw 800, the worm 110 is meshed with the turbine 900, and the output shaft of the motor 120 is connected to the worm 110. This design makes the height adjustment process more automated and labor-saving, and workers can achieve height adjustment without manually rotating the screw 800. The introduction of the motor 120 improves work efficiency, and at the same time, the transmission mechanism of the turbine 900 and the worm 110 ensures the stability and reliability of the transmission, further improving the user experience of the maintenance platform. And because the worm 110 drives the turbine 900 to be a labor-saving transmission part, the motor 120 does not need to be set with a very large torque, and the size of the motor 120 does not need to be too large, which is easy to install.

[0075] In some embodiments, the turbine 900 is disposed at the bottom end of the screw 800 , that is, the turbine 900 is located above the lower connecting rod 700 .

[0076] Further, the turbine 900 is located near the walking path. The turbine 900 is located at the top of the guardrail 500. This position is convenient for manual operation of the motor 120.

[0077] In some embodiments, the motors 120 are connected in series or in parallel. All motors 120 can be started simultaneously to achieve the overall lifting of the pier maintenance platform.

[0078] In some embodiments, a handle is connected to one end of the worm 110 away from the motor 120, and the handle includes a sleeve rod 130 connected to the worm 110, and an inner rod 140 is slidably connected inside the sleeve rod 130. An alternative solution for manually adjusting the height is provided. When the motor 120 fails or needs fine-tuning, the worker can drive the worm 110 to rotate by turning the handle, thereby adjusting the height of the maintenance platform. The sliding connection design of the sleeve rod 130 and the inner rod 140 of the handle allows the handle to be retracted and retracted as needed. When the force is insufficient, the inner rod 140 can be moved away from the sleeve rod 130 to increase the force arm for easy manual operation.

[0079] Furthermore, the inner rod 140 can be telescopically attached to the sliding sleeve rod 130 , and a limiting structure is provided inside the inner rod 140 , so as to prevent the inner rod 140 from being separated from the sleeve rod 130 through the limiting structure.

[0080] In some embodiments, a suspension rope 150 is provided in the upper suspension rod 200, one end of the suspension rope 150 is connected to the upper connecting rod 600, and the other end is connected to the screw rod 800. When the screw rod 800 is separated from the upper suspension rod 200, the suspension rope 150 can be used to pull it to prevent the maintenance half-table from falling off as a whole.

[0081] In some embodiments, a tension spring 160 is disposed in the upper suspension rod 200, one end of the tension spring 160 is connected to the upper connecting rod 600, and the other end is connected to the screw rod 800. The tension spring 160 can also provide a certain buffer force when the screw rod 800 is loose, fails, or falls off from the upper suspension rod 200, thereby preventing the maintenance platform from falling suddenly, further improving the safety of the maintenance operation.

[0082] In some embodiments, the thread direction of the screw rod 800 is opposite to the spiral direction of the tension spring 160. The higher the height of the top of the screw rod 800 from the upper suspension rod 200, the greater the impact force on the walkway 400 when the screw rod 800 is separated from the upper suspension rod 200, and thus the greater the risk of the suspension rope 150 breaking; when the screw rod 800 is screwed in the direction of the upper suspension rod 200, because its thread direction is opposite to the spiral direction of the tension spring 160, the tighter the tension spring 160 is screwed, the greater the tension of the tension spring 160, and when the screw rod 800 is separated from the upper suspension rod 200, the tension spring 160 can better achieve buffering, thereby further reducing the impact of falling, and reducing the risk of the suspension rope 150 breaking, and further improving the safety factor.

[0083] In some embodiments, between multiple beams 100 in the same maintenance half-platform, a positioning rod 300 is provided between any two adjacent beams 100. This design enhances the connection strength and stability between the beams 100. Any two adjacent beams 100 are fixed by the positioning rod 300, making the structure of the entire maintenance half-platform more stable and less prone to deformation or displacement. This helps to ensure the stability and safety of the maintenance platform on the pier, and improve the efficiency and quality of the maintenance work. In addition, during lifting, displacement or offset between the beams 100 is avoided, which facilitates the lifting and installation of the pier maintenance platform.

[0084] Furthermore, the plurality of positioning rods 300 are parallel to each other, which facilitates production and processing.

[0085] Furthermore, the length direction of the plurality of positioning rods 300 is perpendicular to the length direction of the crossbeam 100, which is convenient for production and processing, and also convenient for manual observation of whether the crossbeam 100 is offset or tilted.

[0086] In some embodiments, the positioning rod 300 and the crossbeam 100 may be connected by bolts. In addition, other methods such as riveting, welding, and plugging may also be used.

[0087] In some embodiments, two crossbeams 100 are disposed in the same maintenance half-platform, two mutually parallel positioning rods 300 are disposed between the two crossbeams 100 , and a placement area is formed between the crossbeams 100 and the positioning rods 300 .

[0088] In the installation step, when the cross beam 100 is erected on the upper surface of the pier, specifically: the support pad stone on the top of the pier is placed in the placement area.

[0089] Through the above scheme, after installation, the support pedestal is located in the placement area. Even if shaking occurs, the beam 100 and the positioning rod 300 will abut the side wall of the corresponding support pedestal, thereby avoiding the possibility of the beam 100 and the positioning rod 300 being offset, and further avoiding the possibility of the beam 100 being separated from the pier, thereby improving the overall stability of the pier inspection platform.

[0090] In some embodiments, a bottom support rod is provided below the walkway 400, and the suspension rod 200 is connected to the bottom support rod. The design of the bottom support rod facilitates the connection of the suspension rod 200, and can disperse and transfer the load transferred by the suspension rod 200, making the structure of the entire maintenance platform more stable and reliable. At the same time, the setting of the bottom support rod also improves the wind resistance and earthquake resistance of the maintenance platform, ensuring the safety and stability of the maintenance operation.

[0091] In some embodiments, the bottom support rod is made of 16-gauge channel steel.

[0092] In some embodiments, a lower connecting plate is provided at the bottom end of the suspension rod 200 , and a lower plug hole is opened on the lower connecting plate. The lower plug hole is used for plugging the bottom support rod, so as to facilitate the connection between the bottom support rod and the suspension rod 200 .

[0093] Furthermore, the lower connecting plate adopts a 5mm×50mm triangular limiting steel plate.

[0094] Furthermore, the bottom support rod and the lower connecting plate may be connected by bolts.

[0095] In other embodiments, the bottom support rod is directly connected to the suspension rod 200 by bolts.

[0096] In some embodiments, the guardrail 500 is 1.2 meters high and includes a railing and a plurality of vertical bars, with the vertical bars spaced 1.5 meters apart. This design fully considers the safety and practicality of maintenance work. The 1.2-meter height and the reasonable setting of the vertical bar spacing can effectively prevent the risk of workers falling from a height.

[0097] Furthermore, the vertical rod adopts 75mm×5mm angle steel, which has high structural strength.

[0098] Furthermore, the railing is made of 20 mm round steel. The railing is arranged along the outer edge of the walkway 400 in the extending direction.

[0099] In some embodiments, an oblique rod is further provided between any adjacent vertical rods, the top of the oblique rod is connected to the top of one of the vertical rods, and the bottom of the oblique rod is connected to the bottom of the adjacent vertical rod, so as to block the area between the two vertical rods and further prevent people from falling between the two vertical rods.

Control the position of the cross beam 100 so that the support pedestal is located below the placement area, and lower the maintenance half platform from top to bottom. Until the support pedestal is located in the placement area and the cross beam 100 is supported by the upper surface of the bridge pier. Separate the sling from the maintenance half platform.

[0109] Because the top size of some bridge piers is larger than the size below the pier, it is impossible to install directly from top to bottom. Therefore, the above method is used for installation.

[0110] In some embodiments, the specific step of S500 is: using a height adjustment device to make the distance from the walkway 400 to the beam 100 in the entire pier inspection platform the same.

[0111] It is worth noting that step S500 can be performed before step S100.

[0112] Through the description of multiple embodiments of the bridge pier maintenance platform of the present invention, it can be seen that the embodiments of the bridge pier maintenance platform of the present invention have at least one or more of the following advantages:

[0113] 1. Through two semi-circular walkways 400, it is possible to conveniently use the maintenance half-platform to form a closed circular maintenance platform around the bridge pier. Operators can move directly on the walkway 400 to facilitate their construction or maintenance. This design not only improves the safety of maintenance operations and prevents the risk of workers falling from heights, but also greatly improves the convenience and efficiency of maintenance operations. The semi-circular design of the walkway 400 allows the maintenance platform to fit closely to the bridge pier, while the provision of the guardrail 500 further ensures the safety of the workers. In addition, through the combination of multiple beams 100 and hangers 200, the maintenance platform can be firmly erected on the bridge pier, ensuring the stability and reliability of the maintenance operation. And there is no need to connect the two maintenance half-platforms, which is convenient for installation and dismantling;

[0114] 2. When the screw rod 800 is separated from the upper suspension rod 200, the suspension rope 150 can be used to pull it to prevent the maintenance half platform from falling off as a whole. In addition, the tension spring 160 can also provide a certain buffer force when the screw rod 800 is loose, fails, or falls off from the upper suspension rod 200, preventing the maintenance platform from falling suddenly, further improving the safety of the maintenance operation.

[0115] 3. The higher the height of the top of the screw rod 800 from the upper suspension rod 200, the greater the impact force on the walkway 400 when the screw rod 800 is detached from the upper suspension rod 200, and thus the greater the risk of the suspension rope 150 breaking; when the screw rod 800 is screwed in the direction of the upper suspension rod 200, because its thread direction is opposite to the spiral direction of the tension spring 160, the tighter the tension spring 160 is screwed, the greater the tension of the tension spring 160, and when the screw rod 800 is detached from the upper suspension rod 200, the tension spring 160 can better achieve buffering, thereby further reducing the impact of the fall and the risk of the suspension rope 150 breaking, thereby further improving the safety factor.

[0116] Finally, it should be noted that: the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0117] The above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present invention, which should be included in the scope of the technical solution for protection of the present invention.
