Term interpretation section: the terms "mounted," "connected," "secured," and the like in this disclosure are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally formed; the terms are used in the present disclosure to be understood by those skilled in the art as specific meanings, and the terms are used in the present disclosure as specific meanings, as appropriate, by mechanical connection, electrical connection, direct connection, indirect connection via an intermediate medium, internal connection of two elements, or interaction relationship of two elements.
According to an exemplary embodiment of the utility model, as shown in fig. 1, the tower crane platform guardrail connecting device comprises two connecting plates 1 with the same structure, wherein the connecting plates 1 are cast steel, the integral strength of the connecting device can be improved, the connecting plates 1 comprise a main plate 2, as shown in fig. 2, a first rib plate 3 is arranged at one end of the main plate 2, the first rib plate 3 is perpendicular to the main plate 2, the height of the first rib plate 3 is half of that of the main plate 2, the first rib plate 3 is fixed on the upper side of the end part of the main plate 2, and the top end face of the first rib plate 3 is flush with the top end face of the main plate 2.
The one end that first floor 3 was kept away from to the mainboard is provided with second floor 4, second floor 4 and mainboard 2 mutually perpendicular, and the vertical direction of second floor 4 is the same with first floor 3, the height of second floor 4 is the half of mainboard 2 height, and the downside at the end of mainboard 2 is fixed to second floor 4, and the bottom terminal surface of second floor 4 is parallel and level mutually with the bottom terminal surface of mainboard 2.
Through setting up the upside at the connecting plate terminal surface with first floor, set up the downside at the connecting plate terminal surface with the second floor, when two connecting plates are just placed one by one and are close to each other, the first floor and the second floor at two connecting plate both ends cross each other, make and form the adapter sleeve between two connecting plates to can overlap two connecting plates respectively and establish the both sides of two adjacent guardrail vertical sides, utilize two connecting plates to link together two installation guardrails.
As shown in fig. 3, a third rib plate 5 is disposed at the top of the main board 2, and the third rib plate 5 is fixed on the top end surface of the main board 2, is located in the middle of the top end surface of the main board 2, and is perpendicular to the main board 2, and the perpendicular direction of the third rib plate 5 is the same as the perpendicular direction of the first rib plate 3 and the second rib plate 4.
