reference numbers in the figures: the lifting hook comprises a lifting hook 1, a contact block 2, a mounting rod 3, a spring 4, a mounting block 5, a groove 101, a contact surface 102, a mounting portion 103 and a mounting hole 501.

Detailed Description

The following describes embodiments of the present invention in detail with reference to the accompanying drawings.

As shown in fig. 1-4, a spring hook buffer, including lifting hook 1, groove 101 has been laid on lifting hook 1, installation piece 5 has been laid in groove 101, be equipped with mounting hole 501 in the installation piece 5, spring 4 has been laid in the mounting hole 501, the one end of spring 4 is connected with the one end of installation pole 3, contact block 2 has been laid to the other end of installation pole 3, contact block 2 moves up and down along the vertical direction of contact surface 102, when jack-up or traction starts between lifting hook and heavy object (lifting hook and lifting hook), spring 4 is slowly compressed, contact block 2 moves towards the vertical direction that is close to the contact surface, until the lower extreme and the installation piece 5 upper end of contact surface 102 offset, contact surface 102 does not receive instant oppression when jack-up or traction starts under the effect of spring 4 and reaches good shock attenuation effect, on the other hand also effectively protects contact surface 102, improve factor of safety.

Furthermore, the groove 101 is arranged in the center of the contact surface 102, after the lifting hook 1 is lifted or pulled to start, the stress at the groove 101 is balanced, and the stress of the lifting hook 1 is balanced due to the centered arrangement of the groove 101. The side of installation piece 5 offsets with the internal surface of recess 101, and installation piece 5 can not lead to the pine to take off along with the motion of lifting hook 1 when guaranteeing that lifting hook 1 carries thing or migration, and the upper end of installation piece 5 is less than the upper end of recess 101, and when contact block 2 got into recess 101, the upper end that can realize installation piece 5 offsets with the lower extreme of contact block 2, carries on spacingly and location to contact block 2.

Furthermore, the spring 4 is located in the center of the mounting block 5, so that the force transmitted to the lifting hook 1 after the spring 4 is stressed is balanced, the side surface of the spring 4 is abutted against the inner surface of the mounting hole 501, the spring 4 is prevented from deviating from the mounting hole 501 along with the movement of the lifting hook 1, and the spring 4 can be replaced and adjusted according to actual load to adapt to objects with different weights. Spring 4 is along the vertical direction up-and-down motion of mounting hole 501, and spring 4 does not surpass the upper end of installation piece 5 when extending, guarantees that installation pole 3 is always in mounting hole 501, is favorable to the stability of whole device. When the spring 4 contracts, the side face of the contact block 2 is abutted to the inner surface of the groove 101, the lower end of the contact block 2 is abutted to the upper end of the mounting block 5, the shock absorption effect is achieved, the contact surface is effectively protected, and the safety factor is improved.

Further, the upper end of the contact block 2 is an arc surface with two high sides and a low middle part, when the side surface of the contact block 2 is abutted against the inner surface of the groove 101, the lower end of the contact block 2 is abutted against the upper end of the mounting block 5, and the arc surface of the contact block 2 is connected with the contact surface 102 to form a smooth arc surface.

Further, be equipped with the installation department 103 that is used for installing the lifting hook on lifting hook 1, the lifting hook 1 of being convenient for is installed on the device of each adaptation, and the height that highly is greater than contact block 2 of installation pole 3 has strengthened the shock attenuation effect in the time of multiplicable spring 4 compression when jack-up or traction start between lifting hook and heavy object (lifting hook and lifting hook).

When a spring hook buffer is implemented: lifting hook 1 installs on the device of its adaptation through installation department 103, and when lifting hook 1 hung the heavy object or colluded the object and carry out jack-up or pull, heavy object or object and the cambered surface of contacting block 2 upper end offset, and contacting block 2, installation pole 3 move towards the vertical direction that is close to the contact surface, and spring 4 is compressed.

Further, until the side surface of the contact surface 102 abuts against the groove 101, the lower end of the contact surface 102 abuts against the mounting block 5, the lifting hook 1 lifts or pulls, and further, when a heavy object is unloaded or an object is not hooked, the spring 4 expands, and the contact block 2 and the mounting rod 3 move towards the vertical direction far away from the contact surface.

Although the reference numerals in the figures are used more here: the terms hook 1, contact block 2, mounting rod 3, spring 4, mounting block 5, recess 101, contact surface 102, mounting portion 103, mounting hole 501, etc., but do not exclude the possibility of using other terms; these terms are used merely to more conveniently describe and explain the nature of the present invention; they are to be construed in a manner that is inconsistent with the spirit of the invention.
