Abstract
The utility model relates to a lifting hook, in particular to a saw bit lifting hook with a buffer protection function. The saw bit lifting hook comprises a lifting hook body and a spring buffer, wherein, the upper end of the lifting hook body is connected with the lower end of the spring buffer; and the upper end of the spring buffer is connected with a wire rope reel of a motor. In the utility model, a central shaft of a machine tool is hung at the center hole of a saw bit; and when a crane continuously hoists upwards the saw bit in a superposition manner, the spring buffer can counteract the upward tensile force of the crane so that the machine tool can not be lifted or the machine tool is damaged so as to set aside enough time for an operator to loosen the crane and recover and ensure normal operation without danger.
Description
Technical field
The utility model relates to suspension hook, particularly a kind of saw blade suspension hook with buffer protection.
Background technology
In the course of processing of major diameter circular saw blade, often it need be lifted on the lathe or from lathe under vertical state and unload, because the centre hole of saw blade cooperates closely with positioning core axle on the lathe, so need fine setting up and down when installing, align installation, even because the speed up and down of crane is the slowest in centre hole, the cooperation of axle also is too fast, therefore, the phenomenon that crane is sling lathe (not having the ground base type) often takes place, if ground is firm, lathe can not be sling, to suspension hook, the lathe mandrel is also can Yin Lali excessive and produce inherent damage, takes off the formation potential safety hazard because of suspension hook collapses in addition sometimes.
Summary of the invention
The utility model is intended to solve existing saw blade suspension hook at the security hidden trouble of installing, existing when unloading saw blade, simultaneously lathe itself is carried out perfect protection, and a kind of saw blade suspension hook with buffer protection is provided.
The technical scheme that the described problem that solves the utility model adopts is: a kind of saw blade suspension hook with buffer protection; comprise suspension hook body, spring bumper; the upper end of this suspension hook body is connected with the lower end of this spring bumper, and the upper end of this spring bumper is connected with the motor cable drum.
Compared with prior art, the utility model has been installed a spring bumper at the suspension hook midway location, it has following effect: when crane plays the saw blade of 100-400Kg, energy disperser is failure to actuate, when crane tangles the lathe center shaft by the saw blade centre hole, carry is put continuation when upwards lifting by crane, and pulling force is when reaching 400kg, spring bumper begins to draw back, and offsets the pulling force that crane makes progress, and makes its lathe of can not slinging, perhaps make lathe impaired, flow out time enough to the operator and unclamp crane, recover, guarantee that normal operation does not produce danger again.
Description of drawings
Structural representation when Fig. 1 adopts the spring bumper of leaf spring type structure for the utility model.
Structural representation when Fig. 2 adopts the spring bumper of cylinder Extension Spring-type structure for the utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
The saw blade suspension hook of the described band buffer protection of embodiment is made of suspension hook body 1, spring bumper 2 two parts, and the upper end of this suspension hook body 1 is connected with the lower end of this spring bumper 2, and the upper end of this spring bumper 2 is connected with motor cable drum 3.
Described spring bumper 2 is leaf spring type structure (see figure 1) or cylinder Extension Spring-type structure (see figure 2).
When the utility model is used, draw back stress value and can normally play a protective role,, can design the spring bumper 2 of different stretching resistances again according to actual weight for the saw blade that size differs greatly as long as calculated the minimum of spring.
Claims (2)
1. the saw blade suspension hook with buffer protection comprises suspension hook body, spring bumper, it is characterized in that, the upper end of this suspension hook body is connected with the lower end of spring bumper, and the upper end of this spring bumper is connected with the motor cable drum.
2. the saw blade suspension hook of band buffer protection according to claim 1 is characterized in that, described spring bumper is leaf spring type structure or cylinder Extension Spring-type structure.
