Embodiment 1

[0023] Embodiment 1 This embodiment provides a retractable manhole locker, the structure of which is as follows: figure 1 and 2 As shown, it is mainly composed of a central disc 7, an A support arm and a B support arm. Among them, the A support arm, the B support arm, and the central disc are connected by a cylindrical center pin 8 passing through the center of the central disc 7, and the two supporting arms are connected in a cross manner. The angle α between the two support arms can be rotated at any angle from 0 to 360°.

[0024] The first support arm is mainly composed of a first support arm female end 1 , a first support arm sub-end 3 , and a first tension spring 11 . A groove is formed at one end of the female end 1 of the first support arm, and the sub-end 3 of the first support arm is installed in the groove and can move along the groove. In order to realize the telescopic function, a first tension spring 11 is installed between the first support arm sub-end 3 and t...

Embodiment 2

[0038] Embodiment 2 This embodiment provides a retractable smart manhole locker, the retractable smart manhole locker includes a retractable manhole locker and an electronic alarm device, wherein the retractable manhole locker The basic structure of the retractable manhole locker is the same as that of the retractable manhole locker in Embodiment 1, the difference is: an electronic suction device is provided on the retractable manhole locker, wherein the suction part 17 of the electronic suction device It is fixed on the end of the support arm female end close to the sub-end, and the magnetic block 18 matched with the suction part 17 is fixed at the corresponding position of the sub-end. The installation position is in the free state of the tension spring, and the magnetic block of the sub-end is just close to the suction part. Contact and suction shall prevail, such as Figure 7 shown.

[0039] If the diameter of the manhole is DN450, such as Figure 7 As shown in the figur...

Abstract

The invention belongs to the technical field of maintenance of chemical production equipment, and particularly relates to temporary locking equipment for opening a manhole of chemical production equipment. A telescopic manhole locker comprises two supporting arms which are connected in a crossed mode, and the included angle of the two supporting arms is adjustable. The supporting arm is of a telescopic structure and is provided with a mother end and a son end, and the son end is movably connected with the mother end. Compared with the prior art, the telescopic manhole locker has the advantages that the telescopic manhole locker is attractive and standard, the installation angle is not limited, assembly and disassembly are convenient, warning slogans are easy to arrange, and intelligent alarming is achieved.

Description

technical field [0001] The invention belongs to the technical field of overhaul of chemical production equipment, in particular to a temporary locking device for opening manholes in chemical production equipment. Background technique [0002] Various types of towers, kettles, tanks, tanks, furnaces, containers and other restricted spaces in chemical production units must meet the relevant requirements of the "Safety Regulations for Operation in Restricted Spaces of Chemical Production Units" (AQ3028-2008) when shutting down for maintenance. That is, a "Confined Space Safety Operation Certificate" should be issued, and meet the standards for safety isolation, cleaning or replacement, ventilation, monitoring, personal protective measures, lighting and electricity safety, guardianship and other safety requirements. The reason why the standard makes such specific requirements is that the risk of safety accidents such as poisoning, suffocation, and flash explosion occurs in confi...
