[0028] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0029] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0030] Please see Figures 1-4 This utility model provides a tunnel cable construction lifting frame, including: a base 1, an auxiliary support mechanism 2 connected to the base 1, a lifting mechanism 3 disposed on the base 1, and a working platform 4 disposed on the lifting mechanism 3.

[0031] In some embodiments, the base 1 is a support part of the tunnel cable construction lifting frame connected to the ground, which includes: a load-bearing frame 11 and a traveling wheel 12 disposed at the bottom of the load-bearing frame 11. The load-bearing frame 11 is a square frame structure used to support the lifting mechanism 3 above, and the traveling wheel 12 is disposed below the load-bearing frame 11 for moving the tunnel cable construction lifting frame.

[0032] In some embodiments, the auxiliary support mechanism 2 is an auxiliary support part in the tunnel cable construction lifting frame, used to enhance the stability of the construction lifting frame and improve the safety of the workers. It includes: a first telescopic arm 21, a second telescopic arm 22 movably connected to the first telescopic arm 21, a support leg 23 connected to the second telescopic arm 22, and a first locking member 24 connected to the first telescopic arm 21.

[0033] In some embodiments, one end of the first telescopic arm 21 is hinged to the load-bearing frame 11. The hinge point between the first telescopic arm 21 and the load-bearing frame 11 can be used as a shaft drive auxiliary support mechanism 2 to rotate, thereby selecting a suitable position on the ground to assist in supporting the cable construction lifting frame. The second telescopic arm 22 is movably connected to the first telescopic arm 21. For example, the first telescopic arm 21 can be a hollow structure, and the second telescopic arm 22 is slidably connected to the hollow part of the first telescopic arm 21, so that the second telescopic arm 22 can slide in the first telescopic arm 21, thereby adjusting the position of the support leg 23.

[0034] Furthermore, the support leg 23 is connected to the second telescopic arm 22 and, after contacting the ground, serves to assist in supporting the cable construction lifting frame. In some embodiments, the support leg 23 includes: a connecting screw 231, a rotating handle 232 located at the top of the connecting screw 231, and a foot 233 located at the bottom of the connecting screw 231. Furthermore, the second telescopic arm 22 is also provided with a threaded sleeve 221, and the connecting screw 231 is threadedly connected to the threaded sleeve 221. The above structure allows the operator to rotate the rotating handle 232, causing the foot 233 to contact the ground during rotation. The foot 233's contact with the ground assists in supporting the cable construction lifting frame, preventing displacement of the cable construction lifting frame during operation and effectively preventing it from overturning due to operator movement, thereby improving operational safety.

[0035] In some embodiments, after the first locking member 24 is connected to the second telescopic arm 22, it is used to lock the active state of the first telescopic arm 21 and the second telescopic arm 22 to prevent the first telescopic arm 21 and the second telescopic arm 22 from moving relative to each other during operation and causing accidents. For example, the first locking member 24 can be a locking bolt, and the second telescopic arm 22 can be provided with a fixing hole. The active state of the first telescopic arm 21 and the second telescopic arm 22 can be locked by connecting the locking bolt to the fixing hole.

[0036] In some more preferred embodiments, the first telescopic arm 21 is provided with a sliding groove 211, and the second telescopic arm 22 is provided with a sliding key 222 adapted to the sliding groove 211. The sliding key 222 slides in the sliding groove 211, thereby enhancing the smoothness of the extension and retraction of the second telescopic arm 22 and the first telescopic arm 21.

[0037] In some more preferred embodiments, the first telescopic arm 21 is connected to the corner of the square load-bearing frame 11, and the stability of the auxiliary support mechanism 2 for supporting the cable construction lifting frame is further enhanced by increasing the support radius of the support leg 23.

[0038] In some embodiments, the load-bearing frame 11 is further provided with a second locking member 25. The second locking member 25 is connected to the first telescopic arm 21 and is used to lock the hinged state of the first telescopic arm 21 and the load-bearing frame 11. In some embodiments, the second locking member 25 may be a locking bolt. After the second locking member 25 abuts against the first telescopic arm 21, it is limited, thereby preventing the first telescopic arm 21 from deflecting during operation and improving operational safety.

[0039] In some embodiments, the lifting mechanism 3 is a part of the cable construction lifting frame used for lifting the work platform 4, so that workers can fix the tunnel cable at a high position. In some embodiments, the lifting mechanism 3 can be a scissor lift, which is usually driven by a hydraulic or electric system and uses a cross-folding metal bracket to achieve vertical lifting.

[0040] In some embodiments, the work platform 4 is a part for carrying operators to perform construction work, which includes: a work basket 41, a door panel 42 hinged to the work basket 41, a retaining ring 43 provided on the work basket 41, a sliding sleeve 44 provided on the door panel 42, and a third locking member 45 provided in the sliding sleeve 44. After the third locking member 45 is connected to the retaining ring 43, it is used to lock the door panel 42 and the work basket 41 in an active state.

[0041] In some embodiments, the work basket 41 is a platform structure surrounded by guardrails, used to provide a construction site for operators. The door panel 42 is used for operators to enter and exit the work basket 41. Further, the third locking member 45 is an inverted L-shaped structure. The door panel 42 and the work basket 41 can be locked by connecting the vertical part of the third locking member 45 to the sliding sleeve 44 and the retaining ring 43. Alternatively, the door panel 42 and the work basket 41 can be unlocked by lifting the horizontal part of the third locking member 45 to separate the third locking member 45 from the retaining ring 43, so that the operator can enter the work basket 41 through the door panel 42.

[0042] Finally, it should be noted that the embodiments disclosed in this utility model are merely preferred embodiments of this utility model and are only used to illustrate the technical solutions of this utility model, not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
