[0001] The utility model relates to the field of roads and bridges, in particular to a bridge and culvert construction safety production platform with a protective structure. Background Art

[0002] Bridges and culverts are collectively referred to as bridges and culverts. They are engineering terms and customary names. Bridges and culverts are mainly composed of superstructures, substructures, and foundation structures. The superstructure includes load-bearing structures, bridge deck pavement, and sidewalks; the substructure includes abutments and piers or cable towers; the foundation is a structure that transfers the various loads borne by bridge piers and abutments to the foundation;

[0003] After searching, a Chinese patent discloses a road and bridge construction platform (publication number CN 216339061U). This patent technology only needs to support the equipment through the setting of adjustment components and support components, thereby achieving stable parking of the equipment. The lifting component is driven to rotate by the control component, and the platform is driven to move upward, thereby achieving the lifting and lowering of the equipment and facilitating storage. However, in the technical solution of the above patent document, in order to facilitate retraction and storage, the height of the upper guardrail is relatively low, which makes it difficult to protect the safety of the construction workers standing on the upper side, increasing the possibility of dangerous accidents during construction.

[0004] Therefore, a bridge and culvert construction safety production platform with a protective structure is proposed to solve the above problems. Utility Model Content

When the bridge is repaired and constructed by using this device, the workbench can be lifted and lowered by the lifting mechanism 2. The platform 3 is raised to a suitable construction height, and then the pushing component 501 is started to raise the guardrail 4 to increase the protective shielding effect on the side of the workbench 3. The supporting and blocking component 502 supports the guardrail 4 when it is raised or lowered, so that the guardrail 4 is more stable and less likely to tilt when it is raised or lowered and slid. The anti-drop mechanism 6 can connect some small tools that are convenient for hooking to prevent them from falling off when workers use them, and to prevent tools from accidentally falling out of their hands.

When it is necessary to raise the guardrail 4 to increase the protective effect during construction, the motor 5011 is manually started at this time, and the motor 5011 drives the gear 5012 to rotate, and the gear 5012 drives the rack 5013 and the guardrail 4 to rise at the same time until the guardrail 4 reaches a suitable protection height, and the motor 5011 is manually turned off. The motor 5011 is a three-phase asynchronous motor. For the staff in this technical field, the motor 5011 is a prior art and will not be described in detail here. The workbench 3 The side end is fixedly connected to the limit frame 5014, and the rack 5013 is slidably connected to the inner wall of the limit frame 5014. When the rack 5013 rotates to drive the rack 5013 to rise, the rack 5013 is prone to shaking and cannot be stably engaged with the gear 5012. The rack 5013 is limited by the limit frame 5014, so that the rack 5013 is more stable when sliding and can be stably engaged with the gear 5012. The side end of the rack 5013 is fixedly connected to the limit rod 5015, and the inner wall of the limit frame 5014 is provided with a limit slot 5016. The limit rod 5015 is slidably connected to the inner wall of the limit slot 5016. When the rack 5013 slides, it will drive the limit rod 5015 to slide on the inner wall of the limit slot 5016, so that when the rack 5013 slides, it will not tilt left or right and will be more stable.

The anti-drop mechanism 6 includes a mounting frame 601 fixedly connected to the upper end of the guardrail 4, and a shrinkage belt 602 is fixedly connected to the inner wall of the mounting frame 601, and a connecting hook 603 is fixedly connected to one end of the shrinkage belt 602. When small tools are used, the hanging ring part of tools such as adjustable wrenches can be connected and fixed by the connecting hook 603. When the tool falls out of the hand, the shrinkage belt 602 will pull the connecting hook 603 and the tool to prevent it from falling out. The shrinkage belt 602 has a coil spring and a connecting belt inside, so that the tool can be pulled without falling when it falls out of the hand. For the staff in this technical field, the shrinkage belt 602 and the connecting hook 603 are both prior art and will not be described in detail here.

When the guardrail 4 rises, it will also drive the blocking plate 5021 to rise. The blocking plate 5021 blocks the gap between the guardrail 4 and the workbench 3 to prevent larger tools such as buckets from falling. When small tools are used, the hanging ring part of tools such as adjustable wrenches can be connected and fixed by connecting the hook 603. When the tool falls out of the hand, the retractable belt 602 will pull the connecting hook 603 and the tool to prevent it from falling. At this time, the guardrail 4 is raised to increase the shielding and protection effect. At the same time, the tool is blocked, the probability of falling is reduced, and it is safer to use. At the same time, the guardrail 4 can be lowered for easy storage.
