[0030] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0031] The embodiment of the present application provides an auxiliary maintenance platform, which can solve the technical problems in the related art that it is inconvenient to enter the maintenance site or it takes a long time and cost to enter the maintenance site by using a climbing platform or setting up a scaffolding platform.
[0032] See also Figure 1 The figure shows an auxiliary maintenance platform provided by an embodiment of the present application, which may include: a maintenance frame 1, which is used to be installed on the pier cap beam 2, and the maintenance frame 1 can be fixed on the pier cap beam 2. When the support is replaced or some positions on the pier cap beam 2 that need maintenance are repaired, the maintenance frame 1 is removed from the pier cap beam 2. A plurality of guardrail mounting rings 11 are fixed on one side of the maintenance frame 1, and at least some of the guardrail mounting rings 11 are arranged at intervals along the height direction of the maintenance frame 1; a standing board 3, which is installed on the maintenance frame 1; at least two steel strands 4, at least two of the steel strands 4 are arranged at intervals along the height direction of the maintenance frame 1, and the steel strands 4 are all passed through the plurality of guardrail mounting rings 11, each of the steel strands 4 extends from one end of the maintenance frame 1 to the other end along the length direction of the maintenance frame 1, and the steel strands 4 passed through the guardrail mounting rings 11 can together form a protective structure, which can ensure rapid construction while protecting the safety of the staff.
[0033] The embodiment of the present application installs the maintenance frame 1 on the bridge pier cap beam 2, so that the staff can replace the support on the standing plate 3. The standing plate 3 can be set to be fixed to each other with the maintenance frame 1. The fixing method can be welding or other methods. The standing plate 3 can also be detachably connected to the maintenance frame 1. When a detachable connection method is adopted, some binding devices can be set between the maintenance frame 1 and the standing plate 3; and the steel strand 4 is passed through the guardrail mounting ring 11 to realize the installation protection of the maintenance frame 1. Since each guardrail mounting ring 11 is fixed to the maintenance frame 1, the steel strand 4 can be quickly positioned and fixed after the maintenance frame 1 is installed. In the embodiment of the present application, the steel strand 4 is set to two, and the two steel strands 4 are along the bridge The height direction of the pier cap beam 2 is set at intervals. In some other embodiments, the steel strands 4 can also be set to two or more, and the steel strands 4 and the guardrail mounting ring 11 can be set on one side of the maintenance frame 1, or can be set on opposite sides of the maintenance frame 1. In the embodiment of the present application, in order to speed up the construction of the auxiliary maintenance platform, the steel strands 4 are installed only on the side of the maintenance frame 1 away from the pier cap beam 2, and the side of the maintenance frame 1 close to the pier cap beam 2 is close to the pier cap beam 2, naturally forming a one-side protection. The embodiment of the present application can realize the rapid construction of the auxiliary maintenance platform without occupying the traffic route, solving the technical problems in the related technology that it is inconvenient to enter the maintenance site or it takes a long time and cost to build a scaffolding platform by using a climbing vehicle platform or setting up a scaffolding platform.
[0034] In some optional embodiments, the maintenance frame 1 may include: two groups of side frames 12, the two groups of side frames 12 are arranged on opposite sides of the standing plate 3; multiple groups of middle frames 13, the middle frames 13 are installed between the two groups of side frames 12, one end of each of the steel strands 4 is fixed to one group of the side frames 12, and the other end is fixed to the other group of the side frames 12. In the embodiment of the present application, the side frames 12 and the middle frames 13 are pre-formed, and they can be easily transported after being built at the construction site. The side frames 12 and the middle frames 13 can be fixed to the pier cap beam 2 respectively, and then the standing plate 3 is fixed to the side frames 12 and the middle frames 13 respectively. Since the mass of the side frames 12 and the middle frames 13 is lighter than the overall mass of the maintenance frame 1, it is also easier to fix the side frames 12 or the middle frames 13 respectively on the pier cap beam 2, reducing the difficulty of installation. Moreover, the side frames 12 and the middle frames 13 are separately arranged, which can adapt to bridge pier cap beams 2 of various sizes. When the size of the bridge pier cap beam 2 is larger, more middle frames 13 can be installed, and the size of the steel strand 4 can be set longer. When the size of the bridge pier cap beam 2 is smaller, fewer middle frames 13 can be installed, and the length of the steel strand 4 can be appropriately reduced.
[0035] In some optional embodiments, the side frame 12 may include: a frame 121, the frame 121 is a quadrilateral structure, and the frame 121 is fixed with a reinforcing side diagonal rod 123. The quadrilateral structure frame 121 formed by the side frame 12 may have a top rod 1213. In the maintenance platform, the top rod 1213 of the side frame 12 may serve as a protective structure at both ends of the maintenance platform to save time for subsequent installation of the protective structure at both ends, and the reinforcing side diagonal rod 123 may enhance the rigidity of the frame 121 and increase the overall bearing capacity of the maintenance platform; a cap beam fixing mechanism 122, the cap beam fixing mechanism 122 is fixed to the frame 121, that is, in the embodiment of the present application, the frame 121 is fixed to the pier cap beam 2 by the cap beam fixing mechanism 122 and the pier cap beam 2.
[0036] In some optional embodiments, the cap beam fixing mechanism 122 may include: a fixed cross bar 1221, the fixed cross bar 1221 is connected to a first fixing member, and the first fixing member fixes the fixed cross bar 1221 to the pier cap beam 2; a fixed vertical bar 1222, one end of the fixed vertical bar 1222 is welded and fixed to the fixed cross bar 1221, and the other end is fixed to the frame 121, the fixed vertical bar 1222 can be integrally formed with a vertical bar of the frame 121, and the fixed cross bar 1221 and the fixed vertical bar 1222 are perpendicular to each other. Preferably, the fixed vertical bar 1222 can also be connected to a first fixing member, and fixing the fixed cross bar 1221 and the fixed vertical bar 1222 to the pier cap beam 2 respectively through the first fixing member can further increase the installation stability of the maintenance frame 1 on the pier cap beam 2. In the embodiment of the present application, mounting holes are provided in both the fixed crossbar 1221 and the fixed vertical bar 1222. The first fixing member is configured as a fixed anchor bolt 15. By inserting the fixed anchor bolt 15 through the mounting hole, time is saved in securing the side frame 12 to the pier cap beam 2. The mutually perpendicular arrangement of the fixed crossbar 1221 and the fixed vertical bar 1222 can meet the requirements of most existing pier cap beams 2. After the fixed crossbar 1221 is secured to the top surface of the pier cap beam 2, the fixed vertical bar 1222 can also be attached to the side of the pier cap beam 2. In some other embodiments, when the shape of the pier cap beam 2 changes, the angle between the fixed crossbar 1221 and the fixed vertical bar 1222 can also be modified accordingly during the prefabrication process.
[0037] In some optional embodiments, the frame 121 includes two side horizontal bars 1211 arranged opposite to each other along the frame 121, and two side vertical bars 1212 fixed on opposite sides of the side horizontal bars 1211. The two side horizontal bars 1211 and the two side vertical bars 1212 together form a quadrilateral structure of the frame 121, the cap beam fixing mechanism 122 is fixed to one of the side vertical bars 1212, and the reinforcing side diagonal bar 123 is provided from the vicinity of the cap beam fixing mechanism 122. One end of the side vertical rod 1212 extends obliquely to one end of the other side vertical rod 1212, that is, the reinforcing side oblique rod 123 extends obliquely from the side of the side vertical rod 1212 close to the pier cap beam 2, close to the top surface of the pier cap beam 2, to the side of the other side vertical rod 1212 away from the top surface of the pier cap beam 2. This arrangement allows the reinforcing side oblique rod to apply pressure to the pier cap beam 2, thereby increasing the bearing capacity and stability of the maintenance frame 1. Preferably, the reinforcing side oblique rod is respectively fixed to the end of the side vertical rod 1212. In some other embodiments, under the premise of meeting the bearing capacity of the maintenance frame 1, the reinforcing side oblique rod 123 can also extend obliquely from the side of the side vertical rod 1212 close to the pier cap beam 2, away from the top surface of the pier cap beam 2, to the side of the other side vertical rod 1212 close to the top surface of the pier cap beam 2. In the embodiment of the present application, the side vertical rod 1212 close to the pier cap beam 2 is integrally formed with the fixed vertical rod 1222; the standing plate 3 is supported on the side horizontal rod 1211, and the side horizontal rod 1211 can be arranged at both ends of the side vertical rod 1212 opposite to the top rod 1213 mentioned in the above embodiment.
[0038] In some optional embodiments, at least part of the guardrail mounting rings 11 are fixed to the side vertical rod 1212 away from the side of the cap beam fixing mechanism 122, and at least part of the guardrail mounting rings 11 are spaced apart along the length direction of the side vertical rod 1212, that is, in each side frame 12, a plurality of guardrail mounting rings 11 are provided, and the plurality of guardrail mounting rings 11 are spaced apart along the length direction of the side vertical rod 1212. The guardrail mounting rings 11 in all side frames 12 can be set accordingly, and each steel strand 4 can be passed through a guardrail mounting ring 11 in a side vertical rod 1212. When each steel strand 4 is fixed through the corresponding guardrail mounting ring 11 in each side frame 12, the steel strand 4 can be parallel to the standing board 3, so that the staff can be protected at the same height at each position on the standing board 3. In the embodiment of the present application, the guardrail mounting ring 11 is only fixed to the side vertical rod 1212 on the side away from the cap beam fixing mechanism 122. Because the side vertical rod 1212 on the side close to the cap beam fixing mechanism 122 can fit tightly with the pier cap beam 2, it has become a protection in itself, which can save resources and installation time. In some other embodiments, the guardrail mounting ring 11 can also be fixed to the side vertical rod 1212 on the side close to the cap beam fixing mechanism 122 to form multiple protections.
[0039] In some optional embodiments, the middle frame 13 may include: a middle cross bar 131, the middle cross bar 131 extends in a direction perpendicular to the extension direction of the standing board 3, and the standing board 3 can be supported on the middle cross bar 131; a first middle vertical bar 132, the first middle vertical bar 132 is fixed to one end of the middle cross bar 131, and the other end of the middle cross bar 131 is fixed with a second middle vertical bar 133. The middle frame 13 can have a substantially similar structure to the side frame 12, and the length of the middle cross bar 131 can also be the same as the length of the side cross bar 1211. The difference is that the top bar 121 of the side frame 12 is not provided in the middle frame 13. 3, so that the staff can pass through the middle frame 13 conveniently; the cap beam fixing rod 134, the cap beam fixing rod 134 is fixed to the first middle vertical rod 132, and the cap beam fixing rod 134 is perpendicular to the first middle vertical rod 132. In the embodiment of the present application, the middle frame 13 is fixed to the pier cap beam 2 by the cap beam fixing rod 134 to achieve the fixation between the middle frame 13 and the pier cap beam 2. Preferably, a plurality of mounting holes can also be opened on the cap beam fixing rod 134, and a mounting hole is also opened at one end of the first middle vertical rod 132 close to the cap beam fixing rod 134, and fixing anchor bolts 15 are passed through the mounting holes. Preferably, the second center vertical rod 133 is also fixed with a guardrail mounting ring 11, and the steel strand 4 is also passed through the guardrail mounting ring 11 of the second center vertical rod 133. The guardrail mounting ring 11 on the second center vertical rod 133 can support the steel strand 4, so that when the two ends of the steel strand 4 need to be fixed on the guardrail mounting ring 11 of the side vertical rod 1212, it is easier to fix because the tension of the steel strand 4's own gravity on the fixed point is reduced.
[0040] Preferably, the middle frame 13 further includes a reinforcing middle diagonal rod 135, and the reinforcing middle diagonal rod 135 extends along the side of the first middle vertical rod 132 close to the cap beam fixing rod 134 to the side of the second middle vertical rod 133 away from the reinforcing middle diagonal rod 135. The arrangement method of the reinforcing middle diagonal rod 135 in the middle frame 13 can be the same as the arrangement method of the reinforcing side diagonal rod 123 in the side frame 12, and preferably, each reinforcing middle diagonal rod 135 and the reinforcing side diagonal rod 123 extend in the same direction and are parallel to each other.
[0041] In some optional embodiments, the auxiliary maintenance platform may further include an anti-falling net 5, which is arranged around the side of the maintenance frame 1. Preferably, the anti-falling net 5 is installed below the maintenance frame 1, and the below here may refer to a position near the bottom of the maintenance frame 1. The anti-falling net 5 cooperates with the steel strand 4 to provide double protection for the workers, and the top of the anti-falling net 5 may contact the steel strand 4. Preferably, the anti-falling net 5 is also fixed to a portion of the frame of the side frame 12.
[0042] An embodiment of the present application also provides an auxiliary maintenance system, which may include an auxiliary maintenance platform as described above. The auxiliary maintenance system also includes a pier cap beam 2. The maintenance frame 1 is installed on the pier cap beam 2 and may be fixed to the top of the pier cap beam 2.
