Description
Technical field
The present invention relates to a kind of anti-tripping, specifically a kind of travelling crane hook is anti-tripping, belongs to field of mechanical technique.
Background technology
Drive a vehicle it is anti-tripping be mainly used in preventing lifting rope or suspender belt from coming off, its material is mostly tagger, is fixed on the small of suspension hook
On axle, it can move up and down.During work, anti-tripping press is inserted in lifting rope or suspender belt, after loosing one's grip because of built in the reason for spring,
It is anti-tripping by upward resilience, be stuck on suspension hook and form closed loop with suspension hook, so as to reach the purpose for preventing that lifting rope or suspender belt from coming off.It is former
Travelling crane hook anti-tripping the defects of existing：There is no fixing device due to anti-tripping, and anti-tripping free end is that point connects with hook
Touch, easily skid, so after long-time use, easy double swerve or slip cause it is anti-tripping pop up, peace can not be played
Full effect.
The content of the invention
In view of the above-mentioned problems of the prior art, a kind of travelling crane hook of present invention offer is anti-tripping, anticreep can be limited
The scope of activities of button, make it is anti-tripping all can not come off or eject from suspension hook under any circumstance, really play a protective role.
To achieve these goals, a kind of travelling crane hook of present invention offer is anti-tripping, including hook body and return spring,
The hook body porch be provided with it is anti-tripping, it is described it is anti-tripping wherein one side be groove surface, the hook body is by straight handle section
Formed with hook section, the junction of the anti-tripping straight handle section and hook section that hook body is arranged on by axle, the Hui Li
Spring one end is mounted on an axle, and the other end is against on anti-tripping free end, and the anti-tripping groove faces out and suspension hook sheet
The hook section free end clamping of body, the anti-tripping free end both sides are respectively connected with a limiting card, and the limiting card is by erecting
The L-shaped that straight section and crosspiece integrally form, wherein vertical section are fixedly connected with anti-tripping free end, and crosspiece is overlapped on hook body
On.
Preferably, return spring is torque spring.
Preferably, the vertical section of limiting card is welded on anti-tripping free end both sides.
Compared with prior art, the present invention is by anti-tripping groove surface and hook body clamping, due to anti-tripping groove surface pair
Quasi- suspension hook free end, and blocked, anti-tripping scope of activities is limited, and anti-tripping groove is with the clamping of suspension hook free end
Linear contact lay, contact surface is larger, is not easy to skid, and avoids its double swerve or slip, efficiently avoid anti-tripping because for a long time
Cause anti-tripping to eject from suspension hook using rear double swerve.Stopping means is provided with anti-tripping free end both sides simultaneously, really
Protected it is anti-tripping can be ejected in no instance from suspension hook, ensured security during lifting hook work and reliable
Property.The present invention is simple in construction, easily fabricated, and cost is low.
Brief description of the drawings
Fig. 1 is overall structure diagram of the present invention.
Embodiment
The invention will be further described below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, a kind of travelling crane hook of the present invention is anti-tripping, including hook body 1 and torque spring, described
It is groove surface that the porch of hook body 1, which is provided with anti-tripping 5, described anti-tripping 5 wherein one sides, and the hook body 1 is by straight handle section
Formed with hook section, described anti-tripping 5 are arranged on the junction of straight handle section and the hook section of hook body 1 by axle 3, described time
The one end of power spring 4 be arranged on axle 3 on, the other end is against on anti-tripping 5 free end, anti-tripping 5 groove face out with
The hook section free end clamping of hook body 1, the anti-tripping 5 free end both sides are respectively connected with a limiting card 2, described spacing
Card 2 is the L-shaped integrally formed by vertical section and crosspiece, and wherein vertical section is connected with anti-tripping 5 free end by way of welding
Together, crosspiece is overlapped in hook body 1.
In this above-mentioned technical proposal, on the one hand because anti-tripping 5 groove surface is directed at the hook section free end of hook body 1,
And blocked, limit anti-tripping 5 scope of activities, avoid its double swerve, efficiently avoid anti-tripping 5 because it is long when
Between cause anti-tripping 5 to be ejected from hook body 1 using rear double swerve.On the other hand, due to the crosspiece of two limiting cards 2
It is overlapped in hook body 1, equivalent to hook body 1 is caught on, even if anti-tripping 5 free end in the course of work because run into meaning
Outside, the free end of hook body 1 is not blocked well, and two crosspieces of limiting card 2 can also catch on hook body 1, be effectively prevented from
Anti-tripping 5 free end is ejected from hook body 1.Anti-tripping 5 groove surface and the free end clamping of hook body 1, with limiting card 2
Apply simultaneously, it is ensured that anti-tripping 5 under any circumstance, is ejected all without from hook body 1, has ensured that hook body 1 exists
Safety and reliability in the course of work.
In use, staff is pushed away with hand by anti-tripping 5 to the inner side of hook body 1, the entrance of hook body 1 is opened, this
When rope is put into hook body 1 again, unclamp hand, due to the characteristic of return spring 4, anti-tripping 5 return spring 4 bullet
Original position is returned under power.
