Abstract
Description
Technical Field
[0001] This application relates to the field of bridge construction technology, and more specifically, to an externally mounted cross-river construction operation platform. Background Technology
[0002] With the development of the times, many places need to build bridges. The completion of bridge construction can improve the convenience of travel for people in the surrounding area in the shortest possible time, and at the same time, it can better drive the development of the surrounding economy.
[0003] However, when constructing bridges across rivers, lakes, and other areas, due to restrictions related to environmental protection and navigation, it is necessary to use external construction platforms for workers to carry out bridge construction. The reliability of the connection between the construction platform and the bridge pier is particularly important, as it directly affects the safety of bridge construction. Moreover, conventional construction platforms are fixedly connected to the bridge piers, which limits the construction scope and affects the convenience of bridge construction. Utility Model Content
[0004] This application provides an external cross-river construction platform that can be reliably connected to bridge piers, expand the construction range, and improve the convenience of bridge construction.
[0005] This application provides an external cross-river construction platform. The construction platform includes a connecting mechanism, a supporting base, a rotating mechanism, and a working platform. The connecting mechanism is used to connect with the pier column and includes a steel clamp, a supporting steel plate, and multiple steel brackets. The steel clamp is used to connect with the pier column, the supporting steel plate is connected to the top of the steel clamp and is arranged around the circumference of the steel clamp, and the multiple steel brackets are distributed at intervals around the circumference of the steel clamp. One end of the steel bracket is connected to the bottom of the supporting steel plate, and the other end is connected to the steel clamp. The two ends of the supporting base are respectively connected to the supporting steel plates of the connecting mechanism on two adjacent pier columns. The rotating mechanism is arranged between the working platform and the supporting base and is used to drive the working platform to rotate, thereby increasing the coverage area of the working platform.
[0006] In this design, the connecting mechanism connects to the bridge piers. The connecting mechanism, with its support base positioned between adjacent piers, provides an installation foundation for the work platform. A rotating mechanism between the support base and the work platform, similar to a conventional work platform where the platform's inability to rotate limits its working area, allows the platform to rotate along its axis, expanding the work area for workers and increasing flexibility. This improves safety and reduces costs. Furthermore, the structural design of the connecting mechanism allows the steel clamps to connect to the piers, while the supporting steel plate connects to the top of the clamps. This increases the support area and connection strength between the connecting mechanism and the support base, making the support base installation on the connecting mechanism more reliable. Multiple steel brackets effectively transfer the load from the supporting steel plate to the piers on the steel clamps, resulting in more even stress distribution and improved structural stability.
[0007] In some embodiments, the steel clamp includes two semi-circular clamping parts, which are connected to form a steel clamp. The size of the steel clamp matches the size of the pier column. The inner peripheral wall of the clamping part has a protruding annular rib, and the outer wall of the pier column is provided with a groove that matches the rib. The rib is inserted into the groove so that the steel clamp is connected to the pier column.
[0008] In the above technical solution, the steel clamp is designed as two semi-circular clamping parts, with annular ribs protruding from the inner circumference of each clamping part. Correspondingly, the outer wall of the pier column has grooves that mate with the ribs. The steel clamp can be secured within these grooves by the ribs, and the grooves provide load-bearing capacity to the steel clamping part, making the connection between the steel clamp and the pier column more convenient and quick, facilitating rapid assembly and disassembly of the connection mechanism. Furthermore, by using the rib-groove combination, the connection stability is ensured, eliminating the need for through-wall rods or high-strength bolts to connect the steel clamp and the pier column. This results in greater construction convenience and minimizes damage to the reinforced concrete structure of the pier column itself.
[0009] In some embodiments, there are multiple ribs, which are spaced apart along the axial direction of the steel clamp.
[0010] In the above technical solution, by using multiple protruding ribs, which are then engaged with multiple grooves on the pier, there are more engagement points and a larger engagement area, which can further improve the connection stability between the steel clamp and the pier, and enhance the safety of workers during construction.
[0011] In some embodiments, each of the two clamping parts is provided with a connecting ear plate at one end facing each other, and the connecting ear plate is provided with a connecting hole for bolts to pass through. The bolts are used to connect the two clamping parts into a whole.
[0012] In the above technical solution, connecting lugs are provided at the opposite ends of the two clamping parts, and bolts are passed through the connecting lugs. The bolts are used to connect the two clamping parts, resulting in strong steel clamping connection stability and easy assembly and disassembly.
[0013] In some embodiments, the support base includes a base plate, a lifting drive component, and a top plate. The base plate is bolted to the connecting mechanism. Multiple fixing through holes are provided at both ends of the base plate along its length. A positioning bolt is inserted into each fixing through hole. The positioning bolt is used to fix the base plate to the supporting steel plate. The lifting drive component is mounted on the base plate. The top plate is connected to the lifting end of the lifting drive component. The rotating mechanism is disposed on the top plate.
[0014] In the above technical solution, when the support base is fixed to the connecting mechanism, it is bolted to the connecting mechanism via positioning bolts, and the connecting mechanism provides stable support to the support base. By adjusting the lifting drive component, the lifting drive component can drive the top plate to rise or fall relative to the base plate, thereby adjusting the height of the working platform.
[0015] In some embodiments, the rotating mechanism includes a slewing bearing and a drive member. The slewing bearing is mounted on the top plate, with its inner ring connected to the top plate and its outer ring connected to the work platform. The drive member is mounted on the top plate and meshes with the teeth of the outer ring of the slewing bearing to drive the slewing bearing to rotate the work platform.
[0016] In the above technical solution, by adopting a rotating mechanism using a slewing bearing and a driving component, the slewing bearing can achieve a stable rotational connection between the working platform and the top plate. Under the action of the driving component, the driving component meshes with the teeth distributed on the outer ring of the slewing bearing. Under the driving action of the driving component, the outer ring of the slewing bearing rotates, thereby causing the working platform to rotate relative to the top plate, realizing the rotation of the working platform along the axial direction of the slewing bearing, and allowing the construction personnel on the working platform to have a wider working range.
[0017] In some embodiments, a guide frame is provided between the top plate and the working platform. The guide frame is installed at the bottom of the working platform and is rotatably fitted with the top plate about the axis of the slewing bearing.
[0018] In the above technical solution, since part of the working platform is suspended in the air, a guide frame is set up to improve the stability of the working platform. On the one hand, the guide frame is set between the working platform and the top plate, which can provide support for the working platform and make the working platform more stable. On the other hand, the guide frame and the top plate are rotatably connected around the axis of the slewing bearing, which can guide the rotation of the working platform, making the rotation of the working platform more stable and safer.
[0019] In some embodiments, the top plate is provided with an annular guide groove arranged around the axis of the slewing bearing, and the guide frame has a guide roller inserted into the guide groove, the guide roller rollingly engaging with the guide groove.
[0020] In the above technical solution, the guide groove and the guide roller at the bottom of the guide frame roll together, and the guide groove provides support and guidance to the guide roller, so that the working platform is more stable and safer when it rotates relative to the top plate.
[0021] In some embodiments, the work platform includes a platform section and a guardrail, the guardrail being disposed around the edge of the platform section, and a hinged guardrail door being disposed on the guardrail.
[0022] In the above technical solution, since the construction work platform is for high-altitude operations, a guardrail is installed on the outer perimeter of the platform to provide a certain degree of protection for construction workers, reduce the risk of falling, and improve safety. The installation of a protective door facilitates the entry and exit of construction workers on the work platform.
[0023] In some embodiments, a 3mm thick close-mesh steel mesh is installed on the outer side of the guardrail.
[0024] In the above technical solution, by setting a 3mm thick close-mesh steel mesh on the outside of the guardrail, and combining the close-mesh steel mesh with the guardrail, the protective ability of the close-mesh steel mesh is stronger, the safety is higher, and the risk of construction workers' tools falling is reduced.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0038] This application provides an externally mounted cross-river construction platform. Please refer to... Figures 1 to 5 The construction platform includes a connecting mechanism 10, a supporting base 20, a rotating mechanism 30, and a working platform 40. The connecting mechanism 10 is used to connect with the pier 200. The connecting mechanism 10 includes a steel clamp 11, a supporting steel plate 12, and multiple steel brackets 13. The steel clamp 11 is used to connect with the pier 200. The supporting steel plate 12 is connected to the top of the steel clamp 11 and is arranged around the circumference of the steel clamp 11. The multiple steel brackets 13 are distributed at intervals around the circumference of the steel clamp 11. One end of the steel bracket 13 is connected to the bottom of the supporting steel plate 12, and the other end is connected to the steel clamp 11. The two ends of the supporting base 20 are respectively connected to the supporting steel plates 12 of the connecting mechanism on two adjacent piers 200. The rotating mechanism 30 is arranged between the working platform 40 and the supporting base 20. The rotating mechanism 30 is used to drive the working platform 40 to rotate, so as to increase the coverage area of the working platform 40.
[0039] In this scheme, the connecting mechanism 10 can be connected to the bridge pier 200. The connecting mechanism 10 can be used to support the base 20 between the connecting mechanisms on two adjacent piers 200, providing an installation foundation for the work platform 40. Furthermore, by setting a rotating mechanism 30 between the support base 20 and the work platform 40, which is equivalent to a conventional work platform 40, the work platform 40 itself cannot rotate, resulting in a relatively limited working area. With the setting of the rotating mechanism 30, the rotating mechanism 30 can drive the work platform 40 to rotate along the axis of the rotating mechanism 30, thereby allowing the construction personnel on the work platform 40 to have a wider working range and more flexible construction, improving construction safety while reducing construction costs. Furthermore, by structurally designing the connecting mechanism 10, the steel clamp 11 is connected to the pier column 200, and the supporting steel plate 12 is connected to the top of the steel clamp 11. The supporting steel plate 12 can increase the support area and connection strength between the connecting mechanism and the supporting base 20, making the installation of the supporting base 20 on the connecting mechanism more reliable. In addition, the setting of multiple steel brackets 13 can effectively transfer the load on the supporting steel plate 12 to the pier column 200 on the steel clamp 11, making the stress transmission more uniform and thus improving the structural stability of the connecting mechanism 10.
[0040] In some embodiments, the steel clamp 11 includes two semi-circular clamp portions 111, which are connected to form the steel clamp 11. The size of the steel clamp 11 matches the size of the pier column 200. The inner peripheral wall of the clamp portion 111 has an annular rib 112 protruding out, and the outer wall of the pier column 200 is provided with a groove 201 that matches the rib 112. The rib 112 is inserted into the groove 201 so that the steel clamp 11 is connected to the pier column 200. By using two semi-circular clamping parts 111 for the steel clamp 11, with annular ribs 112 protruding from the inner circumference of each clamping part 111, and correspondingly, grooves 201 that mate with the ribs 112 are provided on the outer wall of the pier column 200, the steel clamp 11 can be secured in the grooves 201 through the ribs 112. The grooves 201 provide load-bearing capacity to the steel clamp 11, making the connection between the steel clamp 11 and the pier column 200 more convenient and quick, facilitating rapid assembly and disassembly of the connection mechanism. Furthermore, by using the method of ribs 112 mate with grooves 201, the connection stability can be ensured without the need for through-wall rods or high-strength bolts, thus improving construction convenience and minimizing damage to the reinforced concrete structure of the pier column 200 itself.
[0041] The protruding rib 112 and the steel clamp 11 are integrally formed, meaning the protruding rib 112 is also made of steel. Typically, the protective layer thickness of the pier column 200 is approximately 10cm. When constructing the groove 201 on the pier column 200, the thickness of the groove 201 can be controlled between 3cm and 6cm to prevent it from extending into the rebar area of the pier column 200. The corresponding thickness of the protruding rib 112 is also between 3cm and 6cm. After construction, the groove 201 on the surface of the pier column 200 can be repaired using concrete or grout.
[0042] In some embodiments, there are multiple protruding ribs 112, which are spaced apart along the axial direction of the steel clamp 11. By using multiple protruding ribs 112, which engage with multiple grooves 201 on the pier column 200, there are more engagement points and a larger engagement area, which can further improve the connection stability between the steel clamp 11 and the pier column 200 and enhance the safety of construction workers.
[0043] In some embodiments, each of the two clamping parts 111 has a connecting lug 113 at one of its facing ends. The connecting lug 113 has a connecting hole for bolts to pass through, and the bolts are used to connect the two clamping parts 111 into a whole. By providing connecting lugs 113 at one of the facing ends of the two clamping parts 111, and bolts passing through the connecting lugs 113, the two clamping parts 111 are connected using bolts. The steel clamping parts 111 have strong connection stability and are easy to assemble and disassemble.
[0044] Along the axial direction of the steel clamp 11, multiple connecting holes can be provided on the connecting ear plate 113, so that the two clamp parts 111 can be connected by multiple bolts.
[0045] In some embodiments, the support base 20 includes a base plate 21, a lifting drive component 22, and a top plate 23. The base plate 21 is bolted to the connecting mechanism 10. Multiple fixing through holes are provided at both ends of the base plate 21 along its length, and a positioning bolt passes through each fixing through hole. The positioning bolt is used to fix the base plate 21 to the supporting steel plate 12. The lifting drive component 22 is mounted on the base plate 21, and the top plate 23 is connected to the lifting end of the lifting drive component 22. A rotating mechanism 30 is disposed on the top plate 23. When the support base 20 is fixed to the connecting mechanism, it is bolted to the connecting mechanism via the positioning bolts, and the connecting mechanism provides stable support to the support base 20. By adjusting the lifting drive component 22, the lifting drive component 22 can drive the top plate 23 to rise or fall relative to the base plate 21, thereby adjusting the height of the working platform 40.
[0046] Of course, multiple sets of support and guide structures 24 can be provided around the top plate 23 and the base plate 21. The lifting drive component 22 can be a linear drive component 32 such as a cylinder or hydraulic cylinder.
[0047] In some embodiments, the rotating mechanism 30 includes a slewing bearing 31 and a drive member 32. The slewing bearing 31 is mounted on the top plate 23, with its inner ring connected to the top plate 23 and its outer ring connected to the work platform 40. The drive member 32 is mounted on the top plate 23, and its teeth mesh with the outer ring of the slewing bearing 31 to drive the slewing bearing 31 to rotate the work platform 40. By adopting a driving method where the rotating mechanism 30 uses the slewing bearing 31 in conjunction with the drive member 32, the slewing bearing 31 can achieve a stable rotational connection between the work platform 40 and the top plate 23. Under the action of the drive member 32, the drive member 32 meshes with the teeth distributed on the outer ring of the slewing bearing 31. Driven by the drive member 32, the outer ring of the slewing bearing 31 rotates, thereby causing the work platform 40 to rotate relative to the top plate 23. This allows the work platform 40 to rotate along the axial direction of the slewing bearing 31, expanding the working range for the construction workers on the work platform 40.
[0048] In some embodiments, a guide frame 33 is provided between the top plate 23 and the working platform 40. The guide frame 33 is installed at the bottom of the working platform 40, and the guide frame 33 and the top plate 23 are rotatably connected about the axis of the slewing bearing 31. Since a part of the working platform 40 is suspended, in order to improve the stability of the working platform 40, the guide frame 33 is provided. On the one hand, the guide frame 33 is located between the working platform 40 and the top plate 23, and can provide support for the working platform 40, making the support stability of the working platform 40 higher. On the other hand, the rotatable connection between the guide frame 33 and the top plate 23 about the axis of the slewing bearing 31 can guide the rotation of the working platform 40, making the rotation of the working platform 40 more stable and safer.
[0049] In some embodiments, the top plate 23 is provided with an annular guide groove 231 arranged around the axis of the slewing bearing 31, and the guide frame 33 has a guide roller 331 inserted into the guide groove 231, with the guide roller 331 rollingly engaging with the guide groove 231. Through the rolling engagement between the guide groove 231 and the guide roller 331 at the bottom of the guide frame 33, the guide groove 231 provides support and guidance for the guide roller 331, resulting in higher stability and correspondingly higher safety when the work platform 40 rotates relative to the top plate 23.
[0050] In some embodiments, the work platform 40 includes a platform section 41 and a guardrail 42. The guardrail 42 is arranged around the edge of the platform section 41, and a hinged safety door is provided on the guardrail 42. Since the construction work platform 40 is for high-altitude operations, the guardrail 42, which is provided around the platform section 41, can provide a certain degree of protection for construction workers, reduce the risk of falls, and improve safety. The safety door facilitates the entry and exit of construction workers on the work platform 40.
[0051] The platform section 41 can be made of a 5mm thick closed patterned steel plate, which has a certain anti-slip performance. A 20cm high kick plate can be installed around the bottom inner side of the platform section 41.
[0052] In some embodiments, a 3mm thick close-mesh steel mesh 43 is provided on the outer side of the guardrail 42. By providing a 3mm thick close-mesh steel mesh 43 on the outer side of the guardrail 42, and combining the close-mesh steel mesh 43 with the guardrail 42 poles, the close-mesh steel mesh 43 has stronger protective capabilities, higher safety, and reduces the risk of construction workers' tools falling.
[0053] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.
[0054] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
