In the process, coming off for lifting rope causes danger in order to prevent, and an anti-avulsion plate is provided at the mouth of hook of suspension hook, and anti-avulsion plate makes
It avoids coming off for lifting rope well in, good effect is played to lifting safety, but is carried out to heavy items
During lifting, due to article weight, it is necessary to be lifted with coarse lifting rope, when hoisting rope is installed and removed, due to hanging
Dress rope is too thick, and anti-avulsion plate always causes very big interference to the handling of rope, it is sometimes desirable to which two people coordinate, and a people presses anti-avulsion
Plate, another person load and unload hoisting rope, and the back pressure spring of anti-avulsion plate is often stuck, and the process for loading and unloading hoisting rope increases operation wind
Danger, so existing anti-avulsion plate very bad use on heavy suspension hook, therefore, it is necessary to a kind of new devices to solve existing suspension hook
It is inconvenient for use, handling are cumbersome, the problem of more people handling.
Invention content
The utility model proposes a kind of novel overhead traveling crane dropping-proof hook, for solving existing heavy suspension hook anticreep harden structure
Unreasonable the problem of causing more people's cooperations that could be loaded and unloaded to hoisting rope.
In order to realize the purpose of utility model, the utility model adopts the following technical solution：
A kind of novel overhead traveling crane dropping-proof hook, including suspension hook, anti-off board, shaft, weight linear meter, weight body, drawstring and torsion bar；
The suspension hook is arranged on the lower part of boom hoisting, and shaft is horizontally set on the top of side opening in suspension hook, anti-off board top with
Shaft both ends are connected, and are contacted on the right side of anti-off board lower end with suspension hook lower opening portion, the right end of weight linear meter and the left end of anti-off board
Forepart connects, and weight body is arranged on the left end forepart of weight linear meter, and the left end of torsion bar and the upper rear of anti-off board connect, and drawstring is set
Put the right end of torsion bar；The anti-off board is arc plate structure, is provided with shaft through-hole before the upper end of anti-off board, among upper end
Rectangular channel is provided with, the length of anti-off board is more than the minimum widith of suspension hook opening.
The suspension hook is U-shaped structure, and the upper opening portion on the right side of suspension hook lower part is provided with suspension hook through-hole, suspension hook through-hole with it is anti-
De- plate shaft through-hole diameter is consistent, and the upper end of suspension hook is provided with suspension hook external screw thread, and hook nut is provided on suspension hook external screw thread.
The shaft length and anti-off board equivalent width, rear and front end and the anti-off board top shaft through-hole of shaft coordinate
Connection, centre and the suspension hook through-hole of shaft are connected.
The torsion bar is long plate structure, and the right end of torsion bar is provided with through-hole.
The angle more than right angle is formed between the weight linear meter and anti-off board.
By the implementation of the utility model, good using effect is reached：Novel overhead traveling crane dropping-proof hook passes through drawstring
Anti-off board, weight body lever closure anti-off board are opened, the installation for making lifting rope is very convenient, while effectively avoids anticreep
The dead situation of board reduces the demand to personnel, easy to operate, improves production efficiency, ensure that the safety of personnel.
