Abstract
The invention discloses a rapidly mounted and dismounted cat ladder connection structure, which comprises a cat ladder and a connecting body and further comprises ear plates I, ear plates II and hooks, wherein ear plate holes are formed in both the ear plates I and the ear plates II; the ear plates I and the ear plates II are used in pairs; the ear plates I are fixed on the two sides of the lower part of the cat ladder; the ear plates II are fixed on the connecting body and in positions corresponding to the ear plates I; the hooks are fixed on the connecting body above the ear plates II; the upper part of the cat ladder is hooked in the hook grooves of the hooks, and the lower part of the cat ladder penetrates through ear plate holes to be connected with the connecting body through the ear plates I and the ear plates II by pin shafts or bolts. The connection structure provided by the invention is simple, clear in stress, high in stability, and convenient to mount and dismount, and saves time and labor; installation personnel is not required to work high above the ground, the mounting and dismounting of the connection structure can be completed on the ground, and the connection structure can be assembled and dismounted repeatedly, so that the cost is reduced.
Description
Technical field
The present invention relates to a kind of draw bail, relate 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 matters to be solved by this invention 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 invention 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, and 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 present invention 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 present invention is specifically described.
Figure 1 shows that assembling schematic diagram of the present invention.
The present invention includes cat ladder 1, connector, otic placode I2, otic placode II3 and hook 4.
Fig. 2 a, 2b are depicted as the structural representation of otic placode I of the present invention and otic placode II.
In described otic placode I 2 and otic placode II 3, all have lug plate holes.
Figure 3 shows that otic placode assembling partial schematic diagram of the present invention.
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 that the present invention links up with.
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 invention.
When cat ladder 1 is long, on connector vertical direction, differing heights arranges a plurality of hooks 4.
Installation process of the present invention 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 present invention 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.
