[0002] The construction hoist is also called construction elevator, outdoor elevator and personnel and cargo elevator, is the construction machinery of carrying personnel and cargo frequently used in the construction, is mainly used in the construction of the interior and exterior decoration of high -rise building, bridge, chimney and other buildings, the construction hoist cage roof can be used for the installation, disassembly, maintenance and inspection of the construction hoist itself, and the cage roof guardrail is used as the necessary protection device for protecting the operation personnel when operating on the cage roof.

[0003] The specification of Chinese patent publication No.CN219620634U discloses a kind of safety devices of elevator car roof guardrail, the utility model compared with prior art has the advantages that: import and export can be protected and the gap of filling guardrail support is improved, and protection effect is improved.

[0004] But the above-mentioned patent still has the following problems in actual application process: when the staff is in the cage roof safety guardrail and operates, may rely on the guardrail due to own habit, and the guardrail is directly welded on the cage roof, after long time use, the guardrail can be loose due to external factors Welding, but such loosening is difficult for staff to detect with naked eye, so that the staff can be broken at welding place when relying on the guardrail, thereby causing the risk of falling of the staff. Utility model content

[0005] For the above-mentioned prior art, the technical problem to be solved by the utility model is that most of the existing guardrails are welded on the cage roof, and after long time use, the welding place of the guardrail and the cage roof can be loose, and when the staff relies on the guardrail, the guardrail can be broken at welding place, thereby causing the risk of falling of the staff.

[0006] In order to solve the above problems, the utility model provides construction hoist cage roof safety guardrail device, including mounting panel, the upper end four corners of mounting panel all are fixedly connected with main rod, fixedly connected with a plurality of cross bars between two main rods close, the upper end of mounting panel still is fixedly connected with four monitoring components corresponding to four main rods respectively, monitoring component includes fixedly connected on the upper end of mounting panel's positioning board, the upper end of positioning board is fixedly connected with the fender, positioning board and fender all are L type, both ends of positioning board all are fixedly connected with the baffle, the one end of baffle towards positioning board is fixedly connected with pressure sensor, both sides of main rod towards positioning board all are fixedly connected with positioning rod, the outer surface of positioning rod is fixedly provided with inclined rod, the upper end of inclined rod is rotatably connected with adjusting plate, the one end of adjusting plate away from inclined rod is rotatably connected with mounting block, both sides of positioning board towards main rod all are fixedly connected with limit block, the surface of limit block is excavated with sliding slot, limit block and mounting block between fixedly connected with compression spring, the one end of mounting block towards limit block is fixedly connected with top rod, the one end of top rod away from mounting block is in turn movable and passes through compression spring and sliding slot.

[0007] In the construction hoist cage roof safety guardrail device, the four main rods of the guardrail are monitored by the monitoring assembly. When the welding between the main rod and the mounting plate loosens, the rotary motion can be converted into linear motion, thereby moving the top rod to press the pressure sensor. The information of the loosened welding point is transmitted to the worker, prompting the worker to maintain the main rod in time, prolonging the service life of the main rod, and effectively reducing the situation of the worker falling due to the breakage of the guardrail.

[0008] As a further improvement of the present application, the gap is left between the fender and the main rod, and the one end of the top rod away from the mounting block is treated as a round head.

[0009] As a further improvement of the present application, the one end of the top rod away from the mounting block corresponds to the pressure sensor, and a gap is left between the top rod and the pressure sensor.

[0010] As a further improvement of the present application, the diameters of the longitudinal span of the sliding slot are the same, and the width of the sliding slot is greater than the diameter of the top rod.

[0011] As another improvement of the present application, the upper end of the main rod is fixedly connected with a warning light, and the pressure sensor is signal connected with the adjacent warning light.

[0012] In summary, in actual application process, when the staff relies on the cross rod, the cross rod and the main rod bear force together, if the welding point between the main rod and the mounting plate is loose, the main rod will tilt outward with the loose welding point as the center, thus moving the inclined rod, and the adjusting plate also rotates, the mounting block and the top rod move horizontally under the limiting of the sliding groove, so that the top rod contacts the surface of the pressure sensor, thus extruding the pressure sensor, at this time, the corresponding warning light is on, warning the staff that the welding point of the main rod has loosened, urging the staff to maintain it in time, prolonging the service life of the main rod, thus effectively reducing the situation that the staff falls due to the breakage of the guardrail.
