Description
Technical Field
The utility model belongs to the technical field of protector, especially, relate to a hoist gib head anticreep device.
Background
Currently, the current state of the art commonly used in the industry is such that: the hoisting equipment used by the double-beam bridge crane and the engineering and building unit mostly adopts crown blocks, the crown blocks are special equipment which is widely applied, and the safe use of the special equipment is particularly important. The commonly used crown block hook head anti-drop device is a metal elastic sheet reset by a spring, and the metal elastic sheet anti-drop device has a certain anti-drop function, and is shown in figure 1. The shape of the metal elastic sheet is a straight-edge type elastic sheet, as shown in figure 2, and the shape of the anti-falling metal elastic sheet is a C-shaped elastic sheet, as shown in figure 3.
When a crane or an L crane is used for lifting heavy objects, the safe lifting operation is very important, whether the anti-falling device is intact or not is checked, and daily inspection is also carried out. The actual effect of gib head anticreep device brings great hidden danger for the production safety, and it is high to change metal shrapnel price often simultaneously, and the loss is big, causes certain economic loss.
The overhead traveling crane gib head anticreep device is for utilizing the metal shrapnel that the spring resets, no matter be straight flange type or C type metal shrapnel, all has certain anticreep ability, but because metal shrapnel intensity is low, can't bear the collision of wire rope and suspender for a long time, metal shrapnel takes place easily after collision such as wire rope and suspender to warp the anticreep effect variation, and the shell fragment drops even, brings great potential safety hazard for the jack-up operation. The metal shrapnel anti-falling device needs to be periodically checked and replaced, and the use cost is increased.
In summary, the problems of the prior art are as follows:
the existing overhead crane hook head anti-falling device cannot bear the collision of a steel wire rope and a hanging strip for a long time due to low strength of the metal elastic sheet, the metal elastic sheet is easy to deform and have anti-falling effect after the collision of the steel wire rope, the hanging strip and the like, even the elastic sheet falls off, and great potential safety hazards are brought to hoisting operation
Disclosure of Invention
Problem to prior art existence, the utility model provides a hoist gib head anticreep device.
The utility model is realized in such a way that the crane hook head anti-drop device is provided with a hook head;
the anti-falling device is movably arranged on the positioning pin of the hook head through a positioning screw rod;
the anti-falling device is installed by welding the base panel, the front limiting plate and the rear limiting plate on two sides.
Furthermore, a limiting sleeve for preventing the anti-falling device from swinging is sleeved on the locating pin.
Furthermore, mounting holes are formed in two sides of the base panel, and the positioning screw rods are inserted into the mounting holes.
Further, the length of the rear part anti-falling device of the mounting hole is greater than that of the front part anti-falling device of the mounting hole, and the weight of the rear part anti-falling device of the mounting hole is greater than that of the front part anti-falling device of the mounting hole.
Furthermore, the base panel, the front limiting plate and the rear limiting plate are all made of steel plates with the thickness of 4-6 mm.
In summary, the advantages and positive effects of the invention are: this crane gib head anti-disengaging device simple structure welds with low costsly, and maneuverability is strong durable, verifies through the field usage that this anti-disengaging device intensity is high, and the use can not be damaged, practices thrift the economy, has anti-disengaging ability reinforce, and anti-disengaging device is striking after the installation, improves jack-up safety guarantee greatly.

Detailed Description
In order to further understand the contents, features and effects of the present invention, the following embodiments are illustrated and described in detail with reference to the accompanying drawings.
Aiming at the problems in the prior art, the invention provides a crane hook head anti-drop device, which is described in detail with reference to fig. 4 to 6.
The utility model discloses mainly break through the drawback of current anticreep device, in order to improve the ability of overhead traveling crane gib head anticreep and anticreep device's durability, reduce because of the gib head takes off the jack-up incident rate that the rope leads to, design a neotype overhead traveling crane gib head anticreep device that has superstrong anticreep ability and overlength is durable.
Through the structural feature of research overhead traveling crane gib head and the drawback of current anticreep device, the utility model discloses utilize lever principle to design a crane gib head anticreep device with steel sheet preparation.
The appearance structure of anticreep device is designed according to the structural feature of gib head, uses the steel sheet welding of 6mm thick to form. The weight of the rear part of the anti-falling device is larger than that of the front part of the anti-falling device after the positioning point is selected by the anti-falling device, the anti-falling device is in a closed state in a free state as shown in figure 4, and when the steel wire rope needs to be replaced, the rear part of the anti-falling device is manually supported and placed into the steel wire rope as shown in figure 5.
As shown in figure 6, the anti-drop device is manufactured by welding the base panels on two sides and the front and rear limiting plates, as shown in figure 6, the specified positions of the base panels on two sides are drilled with mounting holes with the diameter of 8mm, and the limiting sleeve is sleeved on the locating pin to prevent the device from swinging during mounting.
The anti-drop device has the appearance characteristics that: the anti-disengaging device appearance structure is according to the design of gib head structural feature, has the limiting plate around the anti-disengaging device, and the back distance is greater than the place ahead distance and the rear quality is greater than the place ahead quality from the mounting hole, utilizes lever principle to play automatic anticreep effect.
Set up the stop collar on the locating pin: the anti-falling device has a transverse swinging phenomenon after being installed, so that the limiting sleeves are additionally arranged on two sides of the connecting position of the positioning pin and the hook head, and the stability of the anti-falling device is improved.
And (3) welding and manufacturing by using steel plates: the anti-falling device is deformed or even falls off after being used due to low strength in the earlier stage, so the anti-falling device is formed by welding a steel plate with the thickness of 4-6mm, and the durability of the anti-falling device is improved.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and all the modifications and equivalents of the technical spirit of the present invention to any simple modifications of the above embodiments are within the scope of the technical solution of the present invention.
