[0001] The utility model relates to the technical field of water diversion project repair, in particular to an aqueduct guardrail repair construction platform. Background Art

[0002] There are guardrails and sidewalks on both sides of the top of the aqueduct. Most of these guardrails are concrete structures. After years of wind, sun and rain erosion, these guardrails have become dilapidated and their structural strength has been greatly reduced. If they are not repaired in time, pedestrians leaning on the guardrails may easily cause the guardrails to overturn, endangering their personal safety. Secondly, the broken guardrails may also collapse without any warning, posing a huge threat to the personal safety of farmers working in the fields below the aqueduct.

[0003] During the repair process of the aqueduct, the dilapidated concrete guardrails on the aqueduct need to be dismantled and rebuilt. When the workers were carrying out the construction, they found that when using electric drills to construct the guardrails, no protective equipment was set up during the process of workers dismantling the guardrails, which may cause the workers to fall from the aqueduct. Secondly, the fallen guardrail debris can easily threaten the personal safety of farmers working below the aqueduct. Thirdly, the guardrail debris falling into the fields will also cause damage to the crops in the field.

[0004] In summary, there is an urgent need for an aqueduct guardrail repair construction platform to solve or at least partially solve the problems existing in the prior art. Utility Model Content

DETAILED DESCRIPTION

[0024] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below, and preferred embodiments of the present invention are given. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0026] Example:

[0027] See also Figure 1-Figure 4 The present embodiment provides a construction platform for repairing aqueduct guardrails, including a central frame 1, both sides of which are cantilevered outward and connected with cantilever arms 3, and one end of the cantilever arms 3 away from the central frame 1 is connected with an operating platform 4, and two operating platforms 4 are relatively arranged on both sides of the central frame 1, and the entrances and exits of the operating platforms 4 are both oriented toward the central frame 1, so that workers can enter the operating platform 4 from the sidewalk of the aqueduct 6. The central frame and the operating platform 4 are spaced apart. During construction, the guardrail that needs to be repaired on the aqueduct 6 is located in the gap between the central frame 1 and the operating platform 4, so as to facilitate the construction of the guardrail that needs to be repaired on the aqueduct 6 from the operating platform 4 or from the sidewalk of the aqueduct 6. The bottom of the center frame 1 is provided with a moving wheel 2 for supporting the movement of the center frame 1. A plurality of moving wheels 2 are provided, and the plurality of moving wheels 2 are arranged in two rows along the length direction of the center frame 1. The center frame 1 includes a transverse tube 11, a vertical tube 12 and a connecting buckle 13. A plurality of transverse tubes 11, a plurality of vertical tubes 12 and a plurality of connecting buckles 13 are provided. The transverse tube 11 is connected to the vertical tube 12 through the connecting buckle 13. A plurality of transverse tubes 11, a plurality of vertical tubes 12 and a plurality of connecting buckles 13 are constructed into a square frame body. Some transverse tubes 11 are arranged along the width direction of the square frame body, and another portion of the transverse tubes 11 are arranged along the length direction of the square frame body. The transverse tube 11 at the top of the center frame 1 extends along the width direction of the square frame body and cantilevers to the outside of the square frame body to form a cantilever arm 3. The moving wheel 2 is provided at the lower end of the square frame body.

[0028] Specifically, in this embodiment, the moving wheel 2 is a wheel with a brake, and the brake on the wheel prevents the wheel from rolling, thereby preventing the aqueduct guardrail repair construction platform from moving on the aqueduct 6 during construction. The wheel can also be a universal wheel. In other embodiments, the moving wheel 2 can also be an ordinary wheel that can roll. When the ordinary wheel is supported on the upper part of the aqueduct 6, it will not be subject to a large force along the length direction of the aqueduct 6 during construction, so it is not easy to move under friction without a brake.

[0029] It is understandable that when repairing the guardrail of the aqueduct 6, the old guardrail needs to be removed and a new guardrail needs to be installed or cast. When repairing the guardrail on the aqueduct 6, the central frame 1 is installed on the aqueduct 6, and the moving wheels 2 are supported on the sidewalk on the aqueduct 6, so that the operating platform 4 is located outside the guardrail. When constructing the guardrail, the workers can stand on the operating platform 4 and push the guardrail toward the inside of the aqueduct 6 to prevent the guardrail from falling from outside the aqueduct 6 to the bottom of the aqueduct 6 during disassembly, posing a threat to the personal safety of farmers working under the aqueduct 6; or the workers can stand on the sidewalk of the aqueduct 6 and push the guardrail toward the operating platform 4, so that the guardrail falls on the operating platform 4 to prevent the fallen guardrail from falling under the aqueduct 6; and then the construction is carried out section by section along the length direction of the aqueduct 6. After one section of construction is completed, the central frame 1 is pushed to move along the length direction of the aqueduct 6 to facilitate the construction of the guardrail on the subsequent aqueduct 6.

[0030] Further, the moving wheel 2 includes a wheel body 22, a frame body 23 and an adjusting mechanism 21. The wheel body 22 is movably arranged on the frame body 23. Specifically, in this embodiment, the wheel body 22 is rotatably connected to the frame body 23 through a bearing. In other embodiments, the wheel body 22 can also be directly rotatably connected to the frame body 23, or through other structures or structures that can make the wheel body 22 rotate relative to the frame body 23. The adjusting mechanism 21 includes an adjusting nut sleeve 211 and a screw rod 212. One end of the screw rod 212 is connected to the top of the frame body 23 by welding, and the other end of the screw rod 212 is threadedly matched with the adjusting nut sleeve 211 and then extends into the corresponding vertical pipe 12. The adjusting nut sleeve 211 is inserted and arranged at the bottom of the vertical pipe 12 and abuts against the vertical pipe 12. The adjusting nut sleeve 211 is rotatably arranged relative to the vertical pipe 12. Under the action of gravity, the vertical tube 12 abuts against the top of the adjusting nut sleeve 211. When the moving wheels 2 are not in the same plane, the adjusting nut sleeve 211 is rotated to make the screw rod 212 extend or retract from the vertical tube 12, and finally make the moving wheels 2 in the same plane. It should be noted that when rotating the adjusting nut sleeve 211, the worker needs to assist the moving wheel 2 and the screw rod 212 by hand to prevent the screw rod 212 from rotating with the adjusting nut sleeve 211. Two rotating arms are provided on the adjusting nut sleeve 211, and the two rotating arms are arranged at 180 degrees, so that the adjusting nut sleeve 211 can be rotated conveniently by the rotating arms.

[0031] Furthermore, the center frame 1 is provided with supporting feet 14, which are arranged at the four corners of the center frame 1, and the supporting corners are fixedly connected to the vertical pipes 12 at the four corners of the center frame 1. When construction is required, the adjusting nut sleeve 211 is rotated to move the screw rod 212 and the moving wheel 2 upward, so that the four supporting feet 14 are supported on the aqueduct 6. When the aqueduct guardrail repair construction platform needs to be moved, the adjusting nut sleeve 211 is rotated to move the screw rod 212 and the moving wheel 2 downward, so that the moving wheel 2 is supported on the aqueduct 6, which is convenient for pushing the aqueduct guardrail repair construction platform to move along the length direction of the aqueduct 6.

[0032] Furthermore, a fence 41 is provided on the operating platform, and the fence 41 is arranged on a side of the operating platform away from the center frame 1. Specifically, the fence 41 is arranged around the flat plate on the operating platform, and the fences 41 are arranged on three sides of the flat plate away from the aqueduct 6. When workers are constructing the guardrail on the aqueduct 6, the existence of the fence 41 can effectively prevent the workers from falling from the operating platform.

[0033] Furthermore, a protective net 42 is laid on the outside and bottom of the operating platform. The protective net 42 is arranged on the outside of the fence 41 and the bottom of the operating platform. When the fence 41 on the aqueduct 6 is pushed down, the concrete constituting the guardrail is easily broken and scattered. The existence of the protective net 42 prevents the broken concrete fragments from falling into the field below the aqueduct 6. Of course, this protective net 42 can be a flexible net woven by nylon wire, or a rigid net with holes opened on an iron sheet, or a wire mesh woven by steel wire.

[0034] Furthermore, a guide channel steel 5 is provided at the bottom of the central frame 1. The guide channel steel 5 includes two guide channel steels 5. The two guide channel steels 5 are used to be laid on the sidewalks on both sides of the aqueduct 6 respectively, and the notches of the guide channel steels 5 face upward. The moving wheels 2 are supported in the guide channel steels 5. On the one hand, the groove of the guide channel steel 5 is smoother than the surface of the pedestrian crossing of the aqueduct 6. The moving wheels 2 have less resistance when moving in the guide channel steels 5, which facilitates the movement of the central frame 1. In addition, the guide channel steels 5 have a guiding effect on the movement of the moving wheels 2, so that the moving wheels 2 can move along the direction in which the guide channel steels 5 are laid.

[0035] Furthermore, a first diagonal brace 15 is arranged in the vertical plane of the center frame 1, and the first diagonal brace 15 is respectively connected to the vertical tube 12 and the horizontal tube 11 through a plurality of connecting buckles 13, and a triangular structure is formed among the first diagonal brace 15, the vertical tube 12 and the horizontal tube 11, so that the deformation resistance in the vertical plane is improved, thereby increasing the stability of the center frame 1.

[0036] Furthermore, a second diagonal brace 16 is arranged in the horizontal plane of the center frame 1, and the second diagonal brace 16 is connected to the transverse tube 11 arranged along the length direction of the center frame 1 and the transverse tube 11 arranged along the width direction through a connecting buckle 13. A triangular structure is formed between the second diagonal brace 16, the transverse tube 11 arranged along the length direction of the center frame 1, and the transverse tube 11 arranged along the width direction of the center frame 1, so that the deformation resistance in the horizontal plane is improved, and the stability of the center frame 1 is increased.

[0037] Further, refer to Figure 4 A support plate 17 is laid on the horizontal pipe 11 and the vertical pipe 12 at the bottom of the central frame 1. The support plate 17 is used to connect the sidewalks on both sides of the aqueduct 6. In order to conveniently display the second inclined rod 16 in the horizontal plane, Figure 4 The lower right support plate 17 is removed, and in actual production, the support plate 17 is also laid there. During construction, workers can store construction tools on the support plate 17, and secondly, workers can also conveniently walk from the sidewalk on one side of the aqueduct 6 to the sidewalk on the other side of the aqueduct 6 on the support plate 17, which is convenient for passage.

[0038] The working principle of the technical solution of the utility model is: when the aqueduct guardrail repair construction platform is used to repair the old guardrail on the aqueduct 6, firstly, the guide channel steel 5 is laid on the sidewalks on both sides of the aqueduct 6, and the moving wheel 2 at the bottom of the center frame 1 is supported in the groove of the guide channel steel 5, so that the guardrail is located in the middle of the center frame 1 and the operating platform, and then the guardrail can be constructed. During the construction process, the worker stands on the sidewalk of the aqueduct 6 and uses a hammer to hit the guardrail on the aqueduct 6, so that the guardrail on the aqueduct 6 breaks and falls to one side of the operating platform. After the guardrail falls, the worker cleans the guardrail that fell on the operating platform and the debris after the guardrail is broken. In the process of breaking the guardrail, the protective net 42 prevents the debris of the broken guardrail from falling into the farmland below the aqueduct 6. After a section of construction is completed, the center frame 1 is pushed to move along the length direction of the aqueduct 6, and the remaining unprocessed guardrails on the aqueduct 6 are continued to be processed.

[0039] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
