Abstract
The utility model belongs to crampon equipment technical field, a kind of suspension hook blocking device of strap cam formula axis pin.The top of safety card is provided with circular hole, and the circular hole of bolt group through safety card connects together safety card with suspension hook, and safety card is realized by bolt group to be rotated；Double torsion spring is installed between safety card upper end and suspension hook, its lower end is provided with magnet arrangement, and the magnetic force between magnet arrangement and suspension hook is more than the spring force of double torsion spring；The middle part of safety card is provided with cam-type axis pin, and the handle of rotation cam formula axis pin realizes the separation of the magnet arrangement and suspension hook of safety card lower end.Even if the suspension hook blocking device of strap cam formula axis pin, toward when being put into or heavier rigging is taken out out of suspension hook in suspension hook, also only needs an operating personnel, is effectively improved the operating efficiency of lifting by setting cam-type axis pin, magnet arrangement on suspension hook safety card.
Description
Technical field
The utility model belongs to crampon equipment technical field, is related to crampon blocking device, more particularly to one
The suspension hook blocking device of kind strap cam formula axis pin.
Background technology
Existing suspension hook blocking device is typically to set double torsion spring in safety card and suspension hook junction, in the work of spring force
Suspension hook tip inside is tightly pressed against with the lower lower end for causing safety card, so plays the role of mousing-hook.When the rigging in suspension hook
When heavier, operating personnel, which need both hands to lift rigging, to be taken out out of suspension hook, due to safety card under spring force
All the time suspension hook tip inside is pressed in, an other operating personnel is at this moment also needed to and firmly depresses safety card, rigging could take out.
This suspension hook blocking device operates very inconvenient, needs two operating personnel to coordinate and could complete when rigging is heavier.
Utility model content
The purpose of this utility model is to provide a kind of suspension hook blocking device of strap cam formula axis pin, solves general at present hang
The problem of hook blocking device is inconvenient for operation, improves operating efficiency, saves manpower.
The technical solution of the utility model：
A kind of suspension hook blocking device of strap cam formula axis pin, including bolt group, safety card, double torsion spring, cam-type axis pin
And magnet arrangement；The top of safety card is provided with circular hole, and safety card and suspension hook are connected to one by the circular hole of bolt group through safety card
Rise, safety card is realized by bolt group to be rotated；Double torsion spring is installed between safety card upper end and suspension hook, its lower end is provided with magnetic
Iron device, the magnetic force between magnet arrangement and suspension hook are more than the spring force of double torsion spring；The middle part of safety card is provided with convex
Wheeled axis pin, the handle of rotation cam formula axis pin realize the separation of the magnet arrangement and suspension hook of safety card lower end.
The beneficial effects of the utility model：The suspension hook blocking device of strap cam formula axis pin on suspension hook safety card by setting
Cam-type axis pin, magnet arrangement, even if toward when being put into or heavier rigging is taken out out of suspension hook in suspension hook, also only need a behaviour
Make personnel, be effectively improved the operating efficiency of lifting.
Brief description of the drawings
Fig. 1 is the structure scheme of installation of the utility model device.
Fig. 2 is put into the operation chart before (taking-up) for rigging.
Fig. 3 is the partial enlarged view of the utility model device.
In figure：1 bolt group；2 safety cards；3 double torsion springs；4 cam-type axis pins；5 magnet arrangements.
Embodiment
With reference to technical solution and attached drawing, specific embodiment of the present utility model is described in detail；
The device is a kind of blocking device of suspension hook, on suspension hook (as shown in Figure 1, Figure 2 and Figure 3)；
Fig. 1 is the nature of suspension hook blocking device, and safety card lower end is located at suspension hook " a " place at this time, at cam-type axis pin
In naturally drooping state.
Safety card is firmly pressed to suspension hook " b " position, while the handle of rotation cam formula axis pin, is basically perpendicular to handle
Safety card.Since the magnetic force of magnet arrangement is more than the elastic force of double torsion spring, and to be affixed to suspension hook (convex for the cam planes of cam-type axis pin
Take turns as semicircle, as shown in Figure 3), suspension hook blocking device is just in Fig. 2 states at this time.
Such as need rigging being put into suspension hook, it is necessary to make suspension hook blocking device be in Fig. 2 states.When rigging is put into suspension hook, due to
So that the handle of cam-type axis pin rotates down, cam follows handle to rotate together for the effect of rigging, and cam rotation while makes
Safety card departs from suspension hook " b " place (i.e. magnet arrangement disengaging suspension hook " b " place), under spring force in Fig. 1 states, this
When rigging be put into suspension hook, suspension hook blocking device plays the role of mousing-hook.
Such as need rigging taking out suspension hook, also need to make suspension hook blocking device be in Fig. 2 states.When rigging takes out suspension hook,
Since the effect of rigging is so that the handle of cam-type axis pin is rotated up, cam follows handle to rotate together, cam rotation it is same
When cause safety card to depart from suspension hook " b " place (i.e. magnet arrangement disengaging suspension hook " b " place), under spring force in Fig. 1 shapes
State, at this time rigging taking-up.
