Abstract
The invention discloses a ladder stand fixing device. The ladder stand fixing device comprises a lug plate, wherein angle steel is welded on the lug plate; the angle steel and the lug plate form a blocking slot; a hole is formed in the lug plate; a nut is welded on the bottom surface of the lug plate; the center of the nut is superposed with the center of the hole; a bolt is arranged in the nut; round steel is welded on the end part of the bolt. According to the invention, the ladder stand is fixed by the fixing device, so that construction staff is prevented from a safety accident caused by the fact that the ladder stand slides and tilts in a climbing process.
Description
Technical field
The present invention relates to a kind of crawling ladder fixing device, particularly a kind of steel work is climbed and is used ladder securement device.
Background technology
In the beam section manufacturing process of boats and ships, bridge steel structure, the height of beam section is all higher, and site operation personnel need lean against in beam section and climb to top with cat ladder.And there is no the cat ladder of fastening devices, and constructor, climb in process undoubtedly, there is very large potential safety hazard.For this situation, need a kind of crawling ladder fixing device of special use, prevent that constructor from the security incident that cat ladder slides and topples over occurring in the process of climbing.
Summary of the invention
The object of the invention is to provide a kind of crawling ladder fixing device, by the fixing cat ladder of fastening devices, prevents that constructor from the security incident that cat ladder slides and topples over occurring in the process of climbing.
In order to achieve the above object, technical scheme of the present invention is:
, comprise otic placode; On described otic placode, be welded with angle steel, make angle steel and otic placode form a draw-in groove; On described otic placode, offer porosely, the bottom surface of described otic placode is welded with nut, and the center of described nut and the center superposition in hole; In described nut, bolt is installed; The end of described bolt is welded with round steel.
It is the otic placode of 16mm * 221mm * 230mm that described otic placode adopts high * wide * length; Described angle steel adopts equal leg angle; Described bolt adopts the bolt of M22mm * 100mm; Described nut adopts the nut of M22mm.
The otic placode that described otic placode adopts the steel of Q235B material to make; The angle steel that described angle steel adopts the steel of Q235B material to make; The round steel that described round steel adopts the steel of Q235B material to make; Described bolt adopts the high-strength bolt that strength grade is 10.9s; Described nut adopts the high strength nut that strength grade is 10.9s.
The invention has the beneficial effects as follows: a kind of crawling ladder fixing device of the present invention, by otic placode, block cat ladder, the draw-in groove of angle steel and otic placode composition is stuck on the steel plate of beam section simultaneously, by the round steel together with bolt welding, can directly turn bolt and hold out against beam section steel plate, and without other instruments such as spanners, make constructor's convenient installation when operation; Cat ladder is fixed, and by the fixing cat ladder of fastening devices, prevents that constructor from the security incident that cat ladder slides and topples over occurring in the process of climbing, and constructor just can safety work; There is convenient, the easy for installation feature of carrying.
Accompanying drawing explanation
Fig. 1 is the structural representation of crawling ladder fixing device of the present invention;
Fig. 2 is the structural representation of the otic placode of crawling ladder fixing device of the present invention;
Fig. 3 is that crawling ladder fixing device of the present invention is arranged on the structural representation on beam section steel plate.
The specific embodiment
As shown in Figure 1, 2, a kind of crawling ladder fixing device, comprises otic placode 1; On described otic placode 1, be welded with angle steel 4, make angle steel 4 and otic placode 1 form a draw-in groove 7; On described otic placode 1, offer porosely 2, the bottom surface of described otic placode 1 is welded with nut 3, and the center superposition in the center of described nut 3 and hole 2; In described nut 3, bolt 5 is installed; The end of described bolt 5 is welded with round steel 6.It is the otic placode of 16mm * 221mm * 230mm that described otic placode 1 adopts high * wide * length; Described angle steel 4 is equal leg angle, and its length of side * length of side * limit is thick is 75mm * 75mm * 10mm; The draw-in groove that the angle steel 4 that adopts above-mentioned dimensions and otic placode 1 form can more firmly block the steel plate 8 of beam section, by otic placode 1, blocks cat ladder, in fastening and have light effect, is more suitable for assembling; Adopt the angle steel of above-mentioned equilateral size to make crawling ladder fixing device in manufacture process, be more suitable for welding, and the firm degree of welding is better; Described bolt 5 adopts the bolt that specification is M22mm * 100mm; Described nut 3 adopts the nut that specification is M22mm; The bolt, the nut that adopt this specification, fastening effect is better.The otic placode that described otic placode 1 adopts the steel of Q235B material to make; The angle steel that described angle steel 4 adopts the steel of Q235B material to make; The round steel that described round steel 6 adopts the steel of Q235B material to make; Described bolt 5 adopts the high-strength bolt that strength grade is 10.9s; Described nut 3 adopts the high strength nut that strength grade is 10.9s.Adopt the steel of Q235B material to make angle steel, otic placode, and the high-strength bolt of 10.9s, nut can more firmly be fixed cat ladder, while making constructor's operation, safety factor is more increased.
After cat ladder pendulum puts in place, with the otic placode 1 of the present embodiment crawling ladder fixing device, block cat ladder, angle steel 4 and the draw-in groove 7 that otic placode 1 forms are stuck on the steel plate 8 of beam section, as shown in Figure 3 simultaneously; By round steel 6, turn bolt 5, make bolt 5 successively through nut 3 and hole 2, until bolt 5 holds out against beam section steel plate 8, fastening devices is motionless, and cat ladder is fixed, and constructor can safety work.
A kind of crawling ladder fixing device of the present embodiment, by otic placode, block cat ladder, the draw-in groove of angle steel and otic placode composition is stuck on the steel plate of beam section simultaneously, by bolt, hold out against beam section steel plate, cat ladder is fixed, by the fixing cat ladder of fastening devices, prevent that constructor from the security incident that cat ladder slides and topples over occurring in the process of climbing, constructor just can safety work; There is convenient, the easy for installation feature of carrying.
