Description

Crane hook hook fixing device

The present invention relates to a fixing device, and more particularly to a crane hook hook fixing device.

In addition to the method of changing the crane hook, the personnel commanded the crane operator to lower the hook head to the ground, and then the ground personnel removed the fixed shaft baffle and the fixed shaft, and then the old hook was lowered. Then put the new hook on the ground and direct the crane operator to lower the hook head to the hook shaft hole and then install the hook shaft.

The method for replacing the crane hook is because the hook head has an irregular shape, and it is difficult to fix the hook when replacing the hook, and if it is accidentally, it is easy to crush the maintenance personnel. In addition, when disassembling and fixing the hook to fix the shaft, it is necessary for the personnel to command the crane operator to control the hook head to rise and fall, so that the accident of the hook head crushing maintenance personnel is also likely to occur.

In view of this, there is a need to propose a solution to solve the above problems.

The purpose of this creation is to provide a crane hook hook fixing device.

In order to achieve the above object, the crane head hook hook fixing device of the present invention comprises: a base; an arc-shaped support seat disposed on the base for placing the hook head hook upright; and two parallel retaining walls, It is arranged on the base to limit the crane hook hook to prevent it from falling over.

According to the creation of the crane head hook hook fixing device, the utility model further comprises a U-shaped retaining wall, the notch of the U-shaped retaining wall facing the support base, wherein the U-shaped retaining wall can limit the crane hook hook to Prevent it from falling over.

According to the present invention, the crane head hook hook fixing device further comprises a U-shaped retaining wall, wherein the curved support seat is disposed in the recess of the U-shaped retaining wall.

According to the creation of the crane head hook hook fixing device, a horizontal adjusting bolt is further included for adjusting the inclination angle of the support seat.

According to the creation of the crane head hook hook fixing device, the utility model further comprises: two extending legs respectively fixed on two sides of the base; and a plurality of rollers disposed under the two extending legs.

When the crane hook hook fixing device of the present invention is used to replace the crane hook hook, the crane is not required to be used for lifting and lowering, so that the worker may be harmed by pinching or collision.

In order to make the above and other objects, features and advantages of the present invention more comprehensible, the following detailed description will be made in conjunction with the accompanying drawings. In the description of the present invention, the same components are denoted by the same reference numerals and will be described above.

Referring to FIG. 1 and FIG. 2, the crane head hook hook fixing device of the present invention comprises a rectangular base 110, and an extending leg 120 is fixed on each side thereof for raising the base 110. Two rollers 130 are disposed below each of the extending legs 120. The upper surface of the base 110 is provided with two sets of U-shaped retaining walls 141, 142, wherein the notches of the two sets of U-shaped retaining walls 141, 142 face each other. Two parallel retaining walls 143 welded to the base 110 are disposed at positions between the two sets of U-shaped retaining walls 141, 142, and the gap between the two retaining walls 143 directly faces the two sets of U-shaped retaining walls 141. , 142 notch. In addition, an arc-shaped inclined support seat 150 is disposed in the recess of the U-shaped retaining wall 141, and the tilt angle of the support base 150 can be adjusted by a horizontal adjusting bolt 160.

Referring to FIG. 3, according to the present invention, a crane head hook hook fixing device is provided, wherein the crown hook hook 190 can be placed upright on the curved support base 150, and is subjected to the U-shaped retaining walls 141, 142 and the parallel retaining wall 143. The limit is not to be dumped. When the inclination angle of the crane hook hook is to be adjusted, the horizontal adjustment bolt 160 can be rotated to adjust.

When replacing the crane hook hook, the hook is lowered to about 50mm to 100mm from the crane hook hook fixture of the present creation, and then the crane is powered off, hooked, and locked. Then, the hydraulic lifting trolley 180 is moved under the base 110, and the base 110 is raised by the hydraulic lifting trolley 180, so that the supporting base 150 and the crane hook hook 190 are in contact (as shown in FIG. 4), and the fixing bolt is utilized. The hook 190 is fixed.

Then remove the baffle shaft bolts and bolts to remove the hook shaft. Then, the hydraulic lift truck is lowered and pushed out, and the hook is replaced by the stacker. After that, the hydraulic lifting trolley is pushed to the bottom of the base, and the hydraulic lifting trolley is used to adjust the height of the hook, and the hook shaft and the tongue are replaced.

When the crane hook hook fixing device of the present invention is used to replace the crane hook hook, the crane is not required to be used for lifting and lowering, so that the worker may be harmed by pinching or collision.

Although the present invention has been disclosed in the foregoing examples, it is not intended to limit the present invention, and any one of ordinary skill in the art to which the present invention pertains can be modified and modified without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this creation is subject to the definition of the scope of the patent application attached.
