Description
Technical field
The present invention relates to a kind of anti-drop device, more particularly to a kind of crane hook anti-drop device.
Background technology
Suspension hook is the topmost suspender of hoisting machinery, is one of crane important component.Without anti-on old-fashioned crane hook
De- device, rope unhook phenomenon easily occurs in operation process, causes weight to fall, and triggers security incident.
Existing crane hook is equipped with greatly anti-drop device, and wherein most anti-drop device uses spring stop to prevent
De- device and the lever gravity type anti-drop device installed that drilled by neck of hook.But there is spring in spring stop anti-drop device
The problem of easily failure, disconnected spring and rib are easily failed by collision deformation, use time is shorter, need to often change, and increases maintenance cost,
And old-fashioned suspension hook can not be installed, can only integral replacing, it is costly；Lever gravity type anti-drop device, which then exists, to be bored in neck of hook
Hole, influence Suspension hook structure characteristic and security, and old-fashioned suspension hook can not be installed, can only integral replacing, it is costly.
The content of the invention
Filled it is an object of the invention to the problem above for overcoming prior art to exist there is provided a kind of crane hook with anticreep
Put, it is sturdy and durable, workload and maintenance cost that lifting hook looseness preventing device is installed, safeguards and repaired can be reduced, it is adaptable to original
Suspension hook and old-fashioned suspension hook that anti-drop device is damaged.
To realize above-mentioned technical purpose and the technique effect, the present invention is achieved through the following technical solutions：
A kind of crane hook anti-drop device, including two L-shaped escape prevention levers, two semicircle clamping plates and two positioning steel tubes,
The fastener for being used for being fixed in neck of hook is provided between the both ends clamping plate of two semicircle clamping plates, middle part is outwards each
A bearing pin is fixed with, the L-shaped escape prevention lever is formed by stock and quarter butt integrally connected, and is provided with and bearing pin phase positioned at junction
The turn hole of cooperation, two L-shaped escape prevention levers are sheathed on bearing pin respectively by turn hole, are set respectively on the stock and quarter butt
Have and be located at the first connecting hole and second between the connecting hole of size identical first and the second connecting hole, two L-shaped escape prevention levers
Connection hole is respectively connected with a positioning steel tube.
Further, the length of the positioning steel tube is slightly larger than neck of hook diameter and two semicircle clamping plate clamping plate thickness
Summation.
The beneficial effects of the invention are as follows：
The present invention is sturdy and durable, can reduce workload and maintenance cost that lifting hook looseness preventing device is installed, safeguards and repaired, can
It is quick installed on new, old-fashioned suspension hook, to eliminate safe hidden trouble, prevents security incident, ensure the peace of the person and equipment
Entirely.

Fig. 2 is the top view of clipped suspension hook of the present invention；
Label declaration in figure：1- suspension hooks, 2-L shape escape prevention levers, 21- stocks, 22- quarter butts, 23- turn holes, the connecting holes of 24- first,
The connecting holes of 25- second, 3- bearing pins, 4- semicircle clamping plates, 41- fasteners, 5- positioning steel tubes.
Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, the present invention is described in detail.
A kind of crane hook anti-drop device, as depicted in figs. 1 and 2, including two L-shaped escape prevention levers 2, two semicircles
Being provided between clamping plate 4 and two positioning steel tubes 5, the both ends clamping plate of two semicircle clamping plates 4 is used to be fixed in the neck of suspension hook 1
The fastener 41 in portion, middle part is outwards respectively fixed with a bearing pin 3, and the L-shaped escape prevention lever 2 is integrally connected by stock 21 and quarter butt 22
Connect and form, and the turn hole 23 that is engaged with bearing pin 3 is provided with positioned at junction, two L-shaped escape prevention levers 2 pass through 23 points of turn hole
It is not sheathed on bearing pin 3, the connection of the first connecting hole of size identical 24 and second is respectively equipped with the stock 21 and quarter butt 22
It is located at the first connecting hole between hole 25, two L-shaped escape prevention levers 2 and the second connection hole is respectively connected with a positioning steel tube 5.
Further, the length of the positioning steel tube 5 is thick slightly larger than the recess diameter of suspension hook 1 and two clamping plates of semicircle clamping plate 4
The summation of degree.
The operation principle of the present embodiment is：
Before use, two L-shaped escape prevention levers 2 are positioned on two bearing pins 3 of two semicircle clamping plates 4, then with fastener 41
Two semicircle clamping plates 4 are fixed on the neck of suspension hook 1, two L-shaped anticreep thick sticks are fixed with two positioning steel tubes 5 and bolt afterwards
Bar 2, completes the assembling of the present invention.
When being not used usually, two L-shaped escape prevention levers 2 of the invention are center of rotation with bearing pin 3, due to stock 21 from
Body weight makes the hook-bill of quarter butt 22 and suspension hook 1 be in closure state；In use, stock 21 is lifted up, suspension hook 1 is set to open 30
~45° angle, after rope is put into suspension hook 1, the hook-bill for making quarter butt 22 and suspension hook 1 by the own wt of stock 21 is in closed form
State and self-locking, so that it is guaranteed that rope will not fall off.
