Problems solved by technology

Its shortcomings: first, the column and the rod are welded, and the welding part needs to be polished when dismantling; the second is that the welding, removal, and grinding of the column take a long time; the third is that the nylon rope is a flexible material. When an external force is applied, it will produce a certain flexible deformation, which is not good for safety protection

Embodiment 1

[0010] Embodiment 1: with reference to attached figure 1 and 2 . A detachable safety protection railing, including a safety column 1, a safety beam 2, the beam 2 and the column 1 are connected by a hook 3, that is, the hook of the beam is inserted into the sleeve of the column to realize the connection between the beam and the column, and the hook is round The diameter of the ring should be slightly larger than the diameter of the round tube of the beam, so that it is convenient to adjust the distance between the hooks during use, and realize the free connection between the beam and the column; the length of the beam is fixed at 6.02m, and the height of the column is about 1.3m. The uprights can be arranged in the lengthwise direction of the rods according to the length of the rods, the distance between the uprights should be controlled between 2~2.5m, and the uprights and the rods should be fastened with bolts. The bottom of the column is provided with a fastening device 4,...

Embodiment 2

[0011] Embodiment 2: On the basis of Embodiment 1, the bolt 7 is a bolt-shaped wireless pressure sensor, or a bolt-shaped pressure sensor, and the signal output end of the bolt-shaped pressure sensor is connected to the signal input end of the alarm 11 . The bolt-shaped wireless pressure sensor or the pressing portion 8 of the bolt-shaped pressure sensor is the signal detection end of the pressure sensor.

[0012] It should be noted that the bolt-shaped wireless pressure sensor itself is an existing wireless pressure sensor, but its shape is designed as a bolt, and the detection signal output by the bolt-shaped wireless pressure sensor is transmitted to the constructor's mobile phone through the GPS wireless network. The GPS wireless network transmission to the alarm, and the built-in pressure value upper and lower limit comparison software technology are all the use of the existing technology, which is available in the PLC controller and the pressure alarm, and will not be des...

Embodiment 3

[0013] Embodiment 3: On the basis of Embodiments 1 and 2, a warning protection method for a detachable safety protection railing, 1) When the bolt 7 is a bolt-shaped wireless pressure sensor, the bolt-shaped wireless pressure sensor is screwed on the clamping On the splint 6 in the device 4, the pressing part 8 of the bolt-shaped wireless pressure sensor passes through the bolt thread hole on the splint 6 to form a tight fit with the edge of the flange to be clamped. Or within the range of the safety pressure value set by the internal value software of the alarm, the mobile phone or the alarm does not alarm at this time; When the built-in software or the internal value software of the alarm set the safe pressure value range, the bolt-shaped wireless pressure sensor 7 will transmit the top pressure value to the construction worker's mobile phone alarm through the GPS wireless network or to the alarm alarm through the GPS wireless network. Make the constructors and safety superv...

Abstract

The invention relates to a detachable safety protection railing and a safety protection method. The detachable safety protection railing is convenient to quickly assemble and disassemble and has a reliable protection function, the detachable safety protection railing comprises a safety upright post and a safety cross beam, the cross beam is connected with the upright post through a clamping hook, a clamping and fixing device is arranged at the bottom of the upright post and consists of an end plate, a bottom plate, a clamping plate and a bolt, one end of the bottom plate and one end of the clamping plate are welded with the end plate to form a clamping and fixing port, the clamping plate is welded with a connecting nut and provided with a bolt hole at the same time, and the bolt is screwed in a nut screw thread and penetrates through the clamping plate to be tightly matched with the edge of a clamped and fixed flange plate. The detachable safety protection railing has the advantages that 1, the detachable safety protection railing can be recycled, and materials are saved; 2, the assembly and disassembly are simple, convenient and quick, and the production efficiency is greatly improved; and 3, the puller bolt is designed into a bolt-shaped wireless or wired pressure sensor, so that the effect of tightly jacking and locking the edge of the clamped and fixed flange plate is achieved, the tight jacking and locking pressure is monitored in real time, and the absolute safety of construction personnel is ensured.

Description

technical field [0001] The invention relates to a detachable safety protection railing and a safety protection method which are convenient for fast loading and unloading of a fence and have a reliable protection function, belonging to the field of protection railing manufacturing. Background technique [0002] In the construction of existing large-section box-shaped or I-shaped poles, round steel pipes are usually used as columns to weld with the poles, and nylon ropes are tied between the columns to play the role of fence protection. Its shortcomings: first, the column and the rod are welded, and the welding part needs to be polished when dismantling; the second is that the welding, removal, and grinding of the column take a long time; the third is that the nylon rope is a flexible material. When an external force is applied, it will produce a certain flexible deformation, which is unfavorable for safety protection. Contents of the invention [0003] Design purpose: To a...
