Specifically, the boom protection device 100 includes a body 110 and a first telescopic rod 120 telescopically disposed on the body 110. The body 110 may be cylindrical or barrel-shaped, and may extend in a horizontal direction, the first telescopic rod 120 may also extend substantially in a horizontal direction, and one end of the first telescopic rod 120 may be disposed on the body 110, for example, the end is disposed on the surface of the body 110, or it may also be disposed inside the body 110. The other end of the first telescopic rod 120 may extend out of the body 110.
In addition, one end of the first telescopic rod 120, which is disposed on the body 110, can also move along the length direction of the first telescopic rod 120 relative to the body 110, so that the other end can change the distance of the first telescopic rod protruding out of the body 110. The first telescopic rod 120 can be extended and retracted in various manners, for example, the first telescopic rod 120 can be a piston rod, the body 110 can be cylindrical, and a piston of the piston rod can be disposed in the body 110, so as to achieve telescopic movement. Or, the body 110 may be provided with a slide rail, and one end of the first telescopic rod 120 may be provided with a slider slidably disposed on the slide rail.

The first connection portion 121 may have the same structure as or a different structure from the second connection portion 111, and is not particularly limited herein.
It can be understood that the first telescopic rod 120 and the body 110 can move freely, that is, the first telescopic rod 120 can move easily relative to the body 110 under the action of external force. A locking device may be further disposed between the first telescopic rod 120 and the body 110, and the locking device may ensure that the first telescopic rod 120 and the body 110 are fixed at the current position.

Regardless of whether the first telescopic rod 120 is locked with the body 110, one end of the first telescopic rod 120 is not separated from the body 110, so that the distance between the other end of the first telescopic rod 120 and the body 110 is limited to a size range. Since the first telescopic rod 120 and the body 110 are respectively connected to the two suspension arms 200, it can be ensured that the distance between the two suspension arms 200 can be limited within a preset size. The preset size may be set according to an actual safety distance or the like.
When the suspension arm 200 and the elevator 300 are connected, the first telescopic rod 120 can be extended out of the body 110, so that the bottom end of the suspension arm 200 can be hung on a lifting lug from the outside to the inside, and the installation is convenient.

The second connecting portion 111 may also include a second rope 190, a mounting member 130 and a fixing member 140, and the structure and function of the second rope 190 may be the same as those of the first rope 160, that is, the structure of the second connecting portion 111 may be the same as that of the first connecting portion 110, and will not be described herein again. The first connection portion 121 and the second connection portion 111 can facilitate adjusting the position of the boom protection device 100, thereby improving safety performance.
When the boom protection device 100 is used, the first connection portion 121 and the second connection portion 111 may be connected to the two booms 200, respectively, and then the position of the test boom protection device 100 is connected, wherein the uppermost end of the test boom protection device may be more than 80cm from the top end of the boom 200, and the lowermost end of the test boom protection device may be more than 80cm from the bottom end of the boom 200. Meanwhile, the larger the weight of the drilling tool, the closer the boom guard 100 is located to the bottom end of the boom 200. When the drilling tool is required to be lifted up when encountering a blockage, the boom guard 100 can be moved to the direction close to the elevator 300 and then lifted up.

The embodiment further provides a hoisting system, which comprises a hoisting device 400, an elevator 300 and a hoisting tool; one end of a boom 200 of the spreader is connected with an elevator 300, and the other end of the boom 200 is connected with a lifting device 400.
Specifically, the elevator 300 and the lifting device 400 may be structures that are common in the art. The structure of the spreader may be the same as that of the above embodiments, and specific reference is made to the above embodiments, which are not described herein again.
When the suspension arm 200 and the elevator 300 are connected, the first telescopic rod 120 can be extended out of the body 110, so that the bottom end of the suspension arm 200 can be hung on a lifting lug from the outside to the inside, and the installation is convenient.
Taking the insertion pin 500 on the right side in fig. 1 as an example, when the bottom end of the boom 200 on the right side is separated from the lifting lug of the elevator 300 due to the heavy weight of a drilling tool, the bottom end of the boom 200 moves outward in a direction away from the boom 200 on the left side, so that the distance between the two booms 200 is increased, and when the distance reaches a preset size, the boom protection device 100 can limit the boom 200 on the right side from further movement, thereby preventing the surrounding workers from being injured due to the excessively large movement range of the boom 200.
According to the hoisting system provided by the embodiment, through the arrangement of the body and the first telescopic rod, one end of the first telescopic rod is telescopically arranged on the body, and the other end of the first telescopic rod is provided with a first connecting part which is fixedly connected with one suspension arm; one end of the body, which is far away from the first telescopic rod, is provided with a second connecting part which is fixedly connected with the other suspension arm, so that the distance between the two suspension arms can be limited within a preset size; when the suspension arm is separated from the elevator due to the reasons of insufficient splicing of the splicing pin and the like, the suspension arm can be always positioned in the preset size around the other suspension arm under the action of the suspension arm protection device, so that the phenomenon that the suspension arm flies out at a high speed to injure workers is avoided, and the safety of drilling operation is improved.

The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.
In the present application, unless expressly stated or limited otherwise, the first feature may be directly on or directly under the second feature or indirectly via intermediate members. Also, a first feature "on," "over," and "above" a second feature may be directly or diagonally above the second feature, or may simply indicate that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature may be directly under or obliquely under the first feature, or may simply mean that the first feature is at a lesser elevation than the second feature.
In the description above, references to the description of the term "one embodiment," "some embodiments," "an example," "a specific example," or "some examples," etc., mean that a particular feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the invention. In this specification, the schematic representations of the terms used above are not necessarily intended to refer to the same embodiment or example. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples. Furthermore, various embodiments or examples and features of different embodiments or examples described in this specification can be combined and combined by one skilled in the art without contradiction.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
