[0033] In one embodiment, as Figure 2 shown, at least one connecting part 3 is provided on the sleeve part 1, which is configured to allow connection with the safety belt, safety rope (not shown in the figure).
[0034] In this arrangement, when the worker needs to work on the track 10 and needs safety protection, first, the sleeve part 1 is sleeved on the track 10, and the sleeve part 1 is subjected to a force, so that the sleeve part 1 moves along the path constituted by the track 10 to the position convenient for work.
[0035] Then, the fixing part 2 on the sleeve part 1 is arranged on the track 10, and the fixing part 2 is relatively fixed with the track 10. Thus, the sleeve part 1 can be relatively fixed with the track 10.
[0036] Finally, the safety belt, safety rope (not shown in the figure) is arranged on the connecting part 3 located on the sleeve part 1, and the safety belt, safety rope (not shown in the figure) is relatively fixed with the connecting part 3.

Thus, the safety of the worker is ensured.
[0044] According to one preferred embodiment of the present application, as shown in Figure 2 A connecting column 32 is further arranged between the connecting ring 31 and the second fixed plate 12, the end of the connecting column 32 is arranged on the second fixed plate 12 and is fixed relative to the second fixed plate 12. Meanwhile, a connecting hole (not shown in the figure) is further arranged on the connecting column 32, and the connecting ring 31 is arranged in the connecting hole (not shown in the figure). In this way, the connecting ring 31 can rotate along the connecting hole (not shown in the figure). Thus, the convenience of the worker in use can be improved.
[0045] According to one preferred embodiment of the present application, as shown in Figure 2 The connecting part 3 is further arranged on the third fixed plate 13. In this way, the convenience of the worker in use can be further improved.
[0046] In this arrangement, when the worker needs to work on the track 10 and needs safety protection, first, the sleeve part 1 composed of the first fixed plate 11, the second fixed plate 12 and the third fixed plate 13 is sleeved on the track 10, and the track 10 is located in the cavity 14.
[0047] Secondly, an acting force is applied to the connecting part 3, and the acting force drives the sleeve part 1 to move along the path formed by the track 10 to a position facilitating construction and allowing the fixed block 21 to be connected to the bolt 102.
[0048] Then, an acting force is applied to the fixing block 21, so that the fixing block 21 moves outwardly from the accommodating groove 111 and the bolt 102 on the track 10 is arranged in the through hole on the fixing block 21. At this time, the nut 22 is arranged on the bolt 102, and an acting force is applied to the nut 22, so that the nut 22 moves along the bolt 102, thereby fixing the fixing block 21, and further fixing the sleeve part 1 on the track 10. Thus, the device 100 is relatively fixedly connected with the track 10.
[0049] Finally, the safety belt and the safety rope (not shown in the figure) are arranged in the connecting ring 31 by the worker, and are relatively fixed with the connecting ring 31, thereby ensuring the safety of the worker.
[0050] In one embodiment, as shown in Figure 3 The fixing device 100 for being arranged on the track further comprises a limiting part 4 arranged on the sleeve part 1, which is configured to selectively abut against the side surface of the track 10, so as to avoid the sleeve part 1 from being separated from the track 10 when the sleeve part 1 moves along the track.
[0051] In one embodiment, as shown in Figure 3 The limiting part 4 comprises an adjusting column 41 arranged in the first fixing plate 11. In this embodiment, the adjusting column 41 is configured to threadedly cooperate with the first fixing plate 11. In this way, the adjusting column 41 can move radially inwardly or radially outwardly on the first fixing plate 11, so as to selectively abut against the track 10.
[0052] According to a preferred embodiment of the present application, as shown in Figure 3 The limiting part 4 further comprises an abutting disc 42 arranged on the end of the adjusting column 41 on the radially inner side, which is arranged in any structure convenient for abutting against the track 10. In this embodiment, the abutting disc 42 is configured to be circular.
[0053] In this arrangement, when it is needed to move the sleeve part 1 along the track 10, an acting force is applied to the adjusting column 41, so that the adjusting column 41 drives the abutting disc 42 to move radially inwardly or radially outwardly, until the abutting disc 42 and the track 10 have a gap allowing the sleeve part 1 to move, and the sleeve part 1 cannot be separated from the track 10.
[0054] At this time, an acting force is applied to the sleeving part 1, so that the sleeving part 1 moves along the track 10, and the sleeving part 1 can avoid mutual disengagement of the sleeving part 1 and the track 10 during movement along the track 10.
[0055] According to a preferred embodiment of the utility model, as shown in Figure 3 The limiting part 4 further comprises a screw head 43 arranged on the end portion of the adjusting column 41 located on the radial outer side. The screw head 43 is arranged in any structure convenient for holding. In this way, when it is needed to move the abutting disc 42 radially inward or radially outward, the application of the acting force can be facilitated.
[0056] According to a preferred embodiment of the utility model, as shown in Figure 3 The limiting part 4 is arranged in two and is distributed on the first fixed plate 11 and the second fixed plate 12 in a corresponding manner. In this way, the sleeving part 1 can be further abutted on the track 10. At the same time, when it is needed to move the sleeving part 1 along the track 10, the sleeving part 1 can be further limited, so as to avoid mutual disengagement of the sleeving part 1 and the track 10.
[0057] In an embodiment, as shown in Figure 3 The fixing device 100 for being arranged on the track further comprises at least one walking wheel 5 arranged on the sleeving part 1 and used for driving the sleeving part 1 to move along the track 10.
[0058] In the embodiment, the walking wheel 5 is arranged in four and is distributed in a two-by-two opposite manner on the first fixed plate 11 and the second fixed plate, and the walking wheel 5 is in mutual abutment with the track 10. In this way, when it is needed to move the device 100 along the track 10, the walking wheel 5 can convert the sliding friction between the device 100 and the track 10 into rolling friction, so as to reduce the labor intensity of the operator.
[0059] The operation of the fixing device 100 for being arranged on the track according to the utility model is as follows.
[0060] When it is needed for the operator to work on the track 10 and safety protection is needed, first, the sleeving part 1 composed of the first fixed plate 11, the second fixed plate 12 and the third fixed plate 13 is sleeved on the track 10, and the track 10 is located in the cavity 14.
[0061] Secondly, force is applied to the screwing head 43, so that the screwing head 43 transmits the force to the adjusting column 41, thereby driving the adjusting column 41 to drive the abutting disc 42 to move radially inward or radially outward until a gap is formed between the abutting disc 42 and the track 10, which allows the sleeve part 1 to move and the sleeve part 1 cannot be separated from the track 10.
[0062] Thirdly, force is applied to the connecting part 3. During this process, the force will be transmitted along the connecting part 3 to the sleeve part 1 and then to the walking wheel 5 on the sleeve part 1, thereby driving the walking wheel 5 to move. At this time, the walking wheel 5 will move along the track 10, thereby driving the device 100 to move along the track 10 until the device is moved to a position facilitating construction and allowing the fixing block 21 to be connected with the bolt 102.
[0063] Then, force is applied to the fixing block 21, so that the fixing block 21 moves outward from the accommodating groove 111 and the bolt 102 on the track 10 is inserted into the through hole in the fixing block 21. At this time, the nut 22 is arranged on the bolt 102 and force is applied to the nut 22, so that the nut 22 moves along the bolt 102, thereby fixing the fixing block 21 and fixing the sleeve part 1 on the track 10. Thus, the device 100 is relatively fixedly connected with the track 10.
[0064] Meanwhile, force is applied to the screwing head 43 and the adjusting column 41 drives the abutting disc 42 to continuously move radially inward until the abutting disc 42 abuts against the track 10. In this way, the device 100 is further relatively fixed with the track 10.
[0065] Finally, the safety belt and safety rope (not shown in the figure) are inserted into the connecting ring 31 and are relatively fixed with the connecting ring 31, thereby ensuring the safety of the operator.
[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limited. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced equivalently without departing from the purpose and scope of the present application, and all of them should be covered in the scope of the claims of the present application.
