Description
Technical field
The utility model relates to a kind of draw bail, relates in particular to a kind of connection structure of stevedoring crane cat ladder.
Background technology
In prior art, the mounting means of hoisting crane cat ladder is mostly that the two ends up and down of cat ladder are fixed with bolt or bearing pin, when upper and lower two ends distance is excessive, installation personnel cannot be on ground in the face of upper end be fixed, must carry out the fixing of cat ladder top by other object, as double ladder etc., so increased the difficulty that cat ladder is installed, and installation personnel must be climbed and carried out aloft work when cat ladder upper end is installed, for installation exercise has left a potential safety hazard.
Summary of the invention
Technical problem to be solved in the utility model is the defect for the connection structure existence of cat ladder in prior art, and a kind of compact conformation, convenient hoisting crane cat ladder connection structure of installing are provided.
For solving this technical matters, the utility model provides a kind of connection structure of quick handling cat ladder, comprise cat ladder and connector, also comprise otic placode I, otic placode II and hook, in described otic placode I and otic placode II, all have lug plate holes, otic placode I and otic placode II are used in pairs, otic placode I is fixed on both sides, cat ladder bottom, otic placode II is fixed on connector and the corresponding position of otic placode I, hook is fixed on the connector of otic placode II top, described cat ladder top hangs in the hook groove of hook, bottom is used bearing pin or bolt to be connected with connector through lug plate holes by otic placode I and otic placode II.
The otic placode I while of described cat ladder both sides is in inner side or the outside of otic placode II.
On connector, same level position is at least fixed with two hooks.
On connector vertical direction, differing heights arranges a plurality of hooks.
Beneficial effect: the utility model is simple in structure, stressed clear, stability is strong; Easy to loading and unloading, time saving and energy saving, installation personnel, without aloft work, just can complete handling on ground, and the assembly and disassembly that can repeat, and reduces costs.

The specific embodiment
Below in conjunction with drawings and Examples, the utility model is specifically described.
Figure 1 shows that assembling schematic diagram of the present utility model.
The utility model comprises cat ladder 1, connector, otic placode I2, otic placode II3 and hook 4.
Fig. 2 a, 2b are depicted as the structural representation of the utility model otic placode I and otic placode II.
In described otic placode I 2 and otic placode II 3, all have lug plate holes.
Figure 3 shows that the utility model otic placode assembling partial schematic diagram.
Described otic placode I 2 and otic placode II 3 are used in pairs.
Described otic placode I2 is fixed on cat ladder 1 both sides, bottom, and otic placode II3 is fixed on connector and the corresponding position of otic placode I2.
Figure 4 shows that the structural representation of the utility model hook.
Described hook 4 is fixed on the connector of otic placode II3 top.
Described cat ladder 1 top hangs in the hook groove of hook 4, and bottom is used bearing pin or bolt to be connected with connector through lug plate holes by otic placode I 2 and otic placode II 3.
2 whiles of otic placode I of described cat ladder 1 both sides are in inner side or the outside of otic placode II 3.
In order to increase the stability of cat ladder, on the object of cat ladder 1 and installation cat ladder 1, same level position is at least fixed with two pairs of otic placodes, and on connector, same level position is at least fixed with two hooks 4.
Figure 5 shows that many hook operating mode schematic diagrams of the present utility model.
When cat ladder 1 is long, on connector vertical direction, differing heights arranges a plurality of hooks 4.
Installation process of the present utility model is as follows: at two heel post bottom welding otic placode I2 of cat ladder 1; Welding hook 4 on connector, in order to increase the stability of cat ladder 1, mates with the width of cat ladder 1 in the spacing of 4, two hooks 4 of two hooks of same level position welding; The lower position welding otic placode II3 of welding hook 4 on connector, the position of otic placode II3 and cat ladder 1 upper ear plate I2 match; Height between hook 4 and otic placode II3 is linked up with the cross-arm of the cat ladder 1 on 4 to the matched of otic placode I2 with hanging over; During installation, first cat ladder 1 is hung on hook 4, the lug plate holes on otic placode I2 is alignd with the lug plate holes on otic placode II3, two otic placode I 2 can the while in inner side or the outside of two otic placode II 3, then with bearing pin or bolt, otic placode I2 is fixedly connected with otic placode II3, installs.
The utility model is simple in structure, stressed clear, stability is strong; Easy to loading and unloading, time saving and energy saving, installation personnel, without aloft work, just can complete handling on ground, and the assembly and disassembly that can repeat, and reduces costs.
