Abstract
The utility model relates to a ground jack technical field, concretely relates to crane hook, having included the lifting hook body and being located the anticreep ware on the lifting hook body, be formed with the slide rail in the lifting hook, be formed with the slider on the anticreep ware, the slider is installed on the slide rail. Compared with the prior art, need not to dismantle or equipment anticreep ware, the operating mode that just can be applied to the operating mode that needs the anticreep ware and not need the anticreep ware, therefore have the convenient advantage of use, the anticreep ware can be based on and whether has hung the heavy object and decide user state, convenient and fast to it is firm reliable.
Description
Technical field
The utility model relates to hoisting crane technical field, especially crane hook.
Background technology
Suspension hook is modal a kind of suspender in elevator machinery.Because the workplace danger coefficient of suspension hook is higher, if cable wire comes off from suspension hook, easily accidents caused, in Long-Time Service process, the inwall of suspension hook easily weares and teares, and the intensity of suspension hook is reduced, affects service life.Therefore seek a kind of cable wire difficult drop-off, suspension hook inwall is not easy to wear, ensures that the suspension hook in service life is particularly important.
In operation process, suspension hook withstands by the clamp be connected with spring the object that suspension hook flange realizes lock hook, and traditional suspension hook needs when goods breaks off relations directly to remove pressing spring clamp with hand, and so easy card hand, exists certain potential safety hazard.
Summary of the invention
For the deficiencies in the prior art, the utility model provides crane hook, and include hook body and be positioned at the anti-dropping device in described hook body, be formed with slide rail in described suspension hook, described anti-dropping device is formed with slide block, described slide block is arranged on described slide rail.
Further, described anti-dropping device is semi-circular block, and described anti-dropping device one end is formed with described slide block.
Further, the described anti-dropping device other end is arc-shaped.
Further, the internal diameter of described anti-dropping device is less than the internal diameter of described hook body.
Further, the scope of the radian of described anti-dropping device is at 200 ° to 270 °.
The beneficial effects of the utility model are: the Jack suspension hook that the utility model provides, without the need to dismounting or assembling anti-dropping device, just can be applied to the operating mode needing the operating mode of anti-dropping device and do not need anti-dropping device, therefore there is advantage easy to use, anti-dropping device can decide using state according to whether having hung weight, convenient and swift, and solid and reliable.
Accompanying drawing explanation
The structural representation of the crane hook that Fig. 1 provides for the utility model embodiment.
In figure, 101 is hook body, and 1011 is slide rail, and 102 is slide block, and 103 is anti-dropping device.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further:
As shown in Figure 1, the preferred embodiment that provides of the utility model.
Crane hook, can be used in and sling, move, unload in the processes such as weight.
Crane hook, includes hook body 101 and anti-dropping device 103, and wherein, anti-dropping device 103 is positioned in hook body 101, is formed with slide rail 1011 in hook body 101, anti-dropping device 103 is formed with slide block 102, and slide block 102 is arranged on slide rail 1011.
When suspension hook is sling weight, weight will promote slide block 102 and slide on slide rail 1011, anti-dropping device 103 slides along with slide block 102, hook body 101 opening being sealed, forming anticreep operating mode, when putting down weight, slide block 102 is due to Action of Gravity Field, get back to initial position, hook body 101 opening is opened by anti-dropping device 103, just can unload.
Jack suspension hook, without the need to dismounting or assembling anti-dropping device 103, just can be applied to the operating mode needing the operating mode of anti-dropping device 103 and do not need anti-dropping device, therefore there is advantage easy to use, anti-dropping device 103 can decide using state according to whether having hung weight, convenient and swift, and solid and reliable.
In order to better be sealed by hook body 101 opening, anti-dropping device 103 is semi-circular blocks, and anti-dropping device 103 one end is formed with slide block 102, block 103 and slide block 102 is connected as a single entity, anti-dropping device 103 is better slided.
Anti-dropping device 103 other end is arc-shaped, slow down the impact of anti-dropping device 103 pairs of hook body 101.
Particularly, the internal diameter of anti-dropping device 103 is less than the internal diameter of hook body 101, like this, can guarantee that anti-dropping device 103 slides in hook body 101.
In order to make anti-dropping device 103 not easily depart from hook body 101 and hook body 101 opening better can be sealed, the scope of the radian of anti-dropping device 103 is at 200 ° to 270 °.
What describe in above-described embodiment and specification sheets just illustrates principle of the present utility model and most preferred embodiment; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.
Claims (5)
