Detailed Description

The technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are only some embodiments of the present utility model, but not all embodiments, and all other embodiments obtained by those skilled in the art without making creative efforts based on the embodiments of the present utility model are included in the protection scope of the present utility model.

Referring to the drawings, the present embodiment provides a crane hook convenient for replacement, which includes a supporting frame 4, wherein the supporting frame 4 is a smooth steel plate, and a "U" structure is disposed on one side of the steel plate, so that the steel plate and the "U" structure form a sealed "mouth" shape structure. As shown in fig. 1. In addition, a circular mounting hole is formed in the structure in the shape of a Chinese character 'kou', and a hook 6 is rotatably mounted in the mounting hole, wherein the hook 6 comprises a bearing ring 61, a main shaft 62, a clamping ring 63 and a lifting hook 64. As shown in fig. 4.

The top of main shaft 62 is provided with carrier ring 61, and the periphery of main shaft 62 is located the below of carrier ring 61 and is provided with snap ring 63, and the bottom of main shaft 62 is located the below fixed mounting of snap ring 63 and has lifting hook 64. As shown in fig. 5.

Wherein, main shaft 62 passes through snap ring 63 rotation and installs in the mounting hole of seting up of support frame 4 to bear the weight of ring 61 and stretch to the inside of "mouthful" style of calligraphy, in addition, install buckle device 5 between bearing ring 61 and snap ring 63, buckle device 5 includes first snap ring 51, second snap ring 52, and first snap ring 51, second snap ring 52 are two symmetrical semi-circular structures, and threaded hole has been seted up at the both ends of the opening part of first snap ring 51, second snap ring 52 for first snap ring 51, second snap ring 52 can connect through the bolt. The first snap ring 51 and the second snap ring 52 can form a closed ring shape with a hollow center. As shown in fig. 5. And a main shaft 62 is installed between the first snap ring 51 and the second snap ring 52.

In addition, the diameter of the bearing ring 61 is larger than the annular diameter formed by the first clamping ring 51 and the second clamping ring 52, so that the bearing ring 61 can be placed above the first clamping ring 51 and the second clamping ring 52, and the lifting hooks 64 are prevented from sliding off from the mounting holes of the support frame 4 with the main shaft 62. Since the first snap ring 51, the second snap ring 52, and the spindle 62 are not fixedly connected, the spindle 62 can rotate between the first snap ring 51 and the second snap ring 52.

The first snap ring 51 and the second snap ring 52 are connected by bolts, so that the first snap ring 51 and the second snap ring 52 need to be fastened by a spanner when being connected.

In addition, the supporting frame 4 is further provided with a roller 1, a supporting shaft 2 and a connecting device 3, as shown in fig. 1. The circumferential surface of the roller 1 is provided with an annular groove (the annular groove is used for placing a steel cable), as shown in fig. 1. The axle center of the roller 1 is rotatably provided with a supporting shaft 2, two ends of the supporting shaft 2 extend to the outer side of the roller 1, and a connecting device 3 is fixedly arranged on the circumferential surface of the supporting shaft 2. As shown.

The connecting device 3 comprises a first half ring 31 and a second half ring 32, wherein the first half ring 31 and the second half ring 32 are of two semicircular annular structures, one ends of the first half ring 31 and the second half ring 32 are provided with threaded holes, and bolts are rotatably arranged in the threaded holes and used for connecting the first half ring 31 and the second half ring 32. As shown in fig. 3.

In addition, be provided with the backup pad at the other end of first semi-ring 31, the backup pad is provided with the rotation hole towards first semi-ring 31 open-ended one side, and the other end of second semi-ring 32 is close to the position fixed mounting of edge has the arc backup pad, and fixed mounting has the pivoted post in the arc backup pad, and the pivoted post of second semi-ring 32 can rotate the rotation hole of installing at first semi-ring 31 to make first semi-ring 31, the one end that the screw hole can be rotated together of second semi-ring 32 keep away from. As shown in fig. 3.

A steel plate 33 is fixedly installed at the position, close to the edge, of the two ends of the rotating column of the second semi-ring 32, the other end of the steel plate 33 is fixedly installed above the supporting frame 4, and the steel plate 33 and the supporting frame 4 are installed together as shown in fig. 1. The fixed connection of the steel plate 33 and the rotating post on the second half ring 32 can make the connection between the support shaft 2 and the connecting device 3 more firm, thereby ensuring the stability of the hook 64.

In actual life, one end of the steel plate 33 may be directly and fixedly mounted on the support shaft 2 in order to save production cost, and the steel plate 33 may rust or its own hardness may be lowered and need to be replaced as it is used. Since the steel plate 33 is fixedly installed on the support shaft 2, the steel plate is required to be cut when being replaced, time is wasted, and the steel plate 33 can be reduced in time for replacing components when a problem occurs by the connection mode of using bolts on the connection device 3. (wherein, utilize the spanner to dismantle the bolt on the connecting device 3 for the one end of first semi-ring 11 and second semi-ring 32 can separate, thereby make connecting device 3 can dismantle from back shaft 2, thereby make the manual work can change new connecting device 3 and steel sheet 33, avoided the manual work to utilize devices such as gas welding to cut the phenomenon of steel sheet 33, thereby stopped the conflagration phenomenon that the pattern was easy to take place when using the gas welding).

While the basic principles and main features of the present utility model and advantages of the present utility model have been shown and described, it will be understood by those skilled in the art that the present utility model is not limited by the foregoing embodiments, which are described in the foregoing specification merely illustrate the principles of the present utility model, and various changes and modifications may be made therein without departing from the spirit and scope of the utility model as defined in the appended claims and their equivalents.
