A clamping block is slidably connected to the top of the sleeve. The bottom of the clamping block penetrates through the sleeve and is arranged on the top of the baffle. A connecting piece is fixedly connected to the top of the base body. The stability of the replaced hook of this device is not high enough. Content of the Utility Model

[0005] The purpose of the utility model is to provide a crane hook device to solve the problems raised in the background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A crane hook device includes:

[0007] A base body and a slot constructed at the bottom of the base body. A crane hook body is inserted into the inner side of the slot.

[0008] A plurality of corresponding positioning holes are arranged side by side on the side walls of both the hook body and the base body. A positioning plate is arranged on one side wall of the base body. A plurality of positioning rods are integrally formed side by side on one side of the positioning plate. The positioning rods are inserted into the corresponding sides of the positioning holes. Fixing plates are integrally formed on both symmetric side walls of the positioning plate. Corresponding fixing holes are opened on both the fixing plates and the side walls of the base body. And fixing bolts are screwed between the corresponding fixing holes.

[0009] In a further embodiment, the structures between the positioning plate and the positioning rods, and between the positioning plate and the fixing plates are both integrally formed by casting.

[0010] In a further embodiment, a groove is formed on one side wall of the base body, and the positioning plate is inserted into the inner side of the groove.

[0011] In a further embodiment, a grip is connected to the side of the positioning plate away from the groove, and the edges and corners of the grip are in an arc-shaped structure.

[0012] In a further embodiment, a washer is sleeved on the side wall of the fixing bolt, and the washer is supported between the head of the fixing bolt and the corresponding side of the fixing plate.

[0015] Compared with the prior art, the technical effects and advantages of the present utility model are as follows:

[0016] For this crane hook device, although the existing device can relatively conveniently replace the hook body, the replaced hook is limited and fixed by a single positioning rod. In this way, the hook is prone to shaking during use, and the stability is not high enough. In this solution, three parallel positioning rods are inserted into the upper part of the hook for fixation, and the positioning plate on one side of the positioning rod is fixed to the corresponding side of the base body through the fixing bolts on both sides, making the hook body more stable;

[0017] Unscrew the two fixing bolts, and then pull out the positioning plate together with the three positioning rods, and then the hook body can be pulled out downward, and it is relatively convenient to take out the hook body;

[0018] Insert the hook body into the slot and press it tightly, then align the positioning rod with the positioning hole and insert it tightly, and finally tighten the fixing bolt to complete the installation of the hook body. It is relatively convenient to install the hook body;

[0019] This crane hook device has higher stability of the hook body while being convenient for replacement. BRIEF DESCRIPTION OF THE DRAWINGS
