In figure, 1, Anti-hook releasing device, 2, gib head connects bearing pin, 3, front handle, 4, Compress Spring, 5, insurance card, 6, rear handle, 7, chute, 8, spacing hole, 9, slide bar, 10, gib head body, 11, rotary pin shaft, 12, second safety plug, 13, second safety plug pin-and-hole, 14, container cavity.
Detailed description of the invention
Below in conjunction with accompanying drawing, the technical solution of the utility model is described in detail.
Mine lift gib head of the present utility model, is applied to and promotes erecting by overhang place in suspension system, is mainly applicable to the hanging of vertical shaft hoisting well-bucket, hanging basket etc., and the tower crane, the crane hook etc. that also can be used for other industry promote on the gib head of suspension apparatus. This hoist hook header structure is simple, dependable performance insurance, solve and promoted unstable, the illusive drawback of gib head in the past, strengthen the security performance of Hoisting System, the economic loss of having avoided the generation of unhook accident and having caused due to unhook accident, really realize the effect of mine shaft construction kibble hoist dual fail-safe, ensured the safety of mine vertical shaft construction.
As depicted in figs. 1 and 2, mine lift gib head of the present utility model, comprise gib head body 10, this gib head body 10 comprises the container cavity 14 for hoppet or steel wire rope are installed, gib head is installed on the top of gib head body 10 and connects bearing pin 2, gib head body 10 can be rotated around this connection bearing pin 2, easy to use.
The below that is positioned at gib head connection bearing pin 2 on gib head body 10 is hinged with " L " type Anti-hook releasing device 1 by rotary pin shaft 11, is provided with first insurance institution and second insurance institution on Anti-hook releasing device 1. When blocking as shown in Figure 1, first insurance institution is positioned at gib head body 10 back positions, second insurance institution is positioned at container cavity 14 positions. Simultaneously two covers are set on Anti-hook releasing device and are arranged in the locking insurance institution of the back side and the container cavity position of gib head, when needs by hoppet when gib head is taken, must open just rotatable Anti-hook releasing device of Liang Tao insurance institution simultaneously, the Anti-hook releasing device part that is arranged in container cavity is removed, take out hoppet, can make the Liang Tao insurance institution of Anti-hook releasing device form interlocking, avoid the independent insurance institution unhook problem causing that lost efficacy, realize Hoisting System dual fail-safe.
In embodiment of the present utility model, first insurance institution comprises: in the insurance card 5 of Anti-hook releasing device 1 and front handle 3, be added with Compress Spring 4, insurance card 5 is fixed on Anti-hook releasing device 1, Compress Spring 4 penetrates slide bar 9, this slide bar 9 is fixedly connected with front handle 3 and rear handle 6, rear handle 6 can be positioned at chute 7 slips of Anti-hook releasing device 1 rear end, at the back side of gib head body 10, a side of container cavity 14 openings (namely away from) is welded with spacing hole 8, the front end of slide bar 9 inserts in spacing hole 8, can play the locking effect of mousing-hook.
In the time of needs decoupling device, as long as rear handle 6 is pulled back, slide bar 9 moves a certain distance accordingly backward, exits spacing hole 8, and Compress Spring 4 is simultaneously compressed, draws Anti-hook releasing device 1 on then, can reach decoupling device object. When normal condition, after add under Compress Spring 4 effect, slide bar 9 inserts in spacing hole 8. In the time there is no responsive to axial force, slide bar 9 can not pull out voluntarily, can not cause unhook, can play reliable locking effect.
In embodiment of the present utility model, second insurance institution comprises: the front end at Anti-hook releasing device 1 increases a second safety plug pin-and-hole 13, bolt is through on pin-and-hole 13, and the fixing formation of nut second safety plug 12 for the other end, utilizes the spacing Anti-hook releasing device that makes of bolt not open.
When normal operating, first pull down second safety plug 12, then operate Anti-hook releasing device, in the time of first spring failure, still have caging bolt, its Anti-hook releasing device can not be opened, well-bucket and gib head moment link together, and anti-locking hook, realizes security improvement.
Because the first safeties of Anti-hook releasing device are by Compress Spring locking, in actual use procedure because of spring and screw rod corrosion inefficacy, shaft construction environment is poor, trickle large and have the many reasons such as certain corrosivity, in mine vertical shaft practice of construction and operating process, being prone to well-bucket breaks off relations on-the-spot, cause the accident, therefore, the Stud connection that the second insurance of Anti-hook releasing device adopts, solve the problem of the special circumstances inefficacy of first insurance, still have caging bolt to pin Anti-hook releasing device, really realize the effect of dual fail-safe.
Although more than described detailed description of the invention of the present utility model, it will be understood by those of skill in the art that these only illustrate, protection domain of the present utility model is to be limited by appended claims. Those skilled in the art is not deviating under the prerequisite of principle of the present utility model and essence, can make various changes or modifications to these embodiments, but these changes and amendment all fall into protection domain of the present utility model.
