[0016] The following will be combined with the drawings of the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] This embodiment provides a cable car operation area guardrail, such as Figure 1 and Figure 2 As shown, the cableway operation area guardrail includes a vertical pole 1 and a horizontal railing 2. The vertical pole 1 and the horizontal railing 2 are both square tubes. The vertical pole 1 and the horizontal railing 2 cooperate to form a guardrail structure to prevent personnel from mistakenly entering the operation area during the operation of the rope arrangement mechanism to avoid safety accidents. Figure 1As shown, six vertical poles 1 are arranged at the front, middle and rear of the left and right sides of the bottom of the cable crane main beam 3, and the top of the vertical pole 1 is fixedly connected to the cable crane main beam 3 by welding or bolting. The bottom of the vertical pole 1 is provided with a socket 4 for installing the horizontal railing 2. Figure 2 As shown, the pole 1 located at the middle section of the bottom of the cable crane main beam 3 has sockets 4 on its front and rear sides; the pole 1 located at the front end of the bottom of the cable crane main beam 3 has sockets 4 on its rear side; the pole 1 located at the rear end of the bottom of the cable crane main beam 3 has sockets 4 on its front side; Figure 3 As shown, the socket 4 is a rectangular socket, and the top opening of the socket 4 forms a cavity into which the plug 5 can be inserted. Figure 1 As shown, the transverse railings 2 are arranged on the left and right sides of the bottom of the cable crane main beam 3, and extend from the front end of the cable crane main beam 3 to the rear end of the cable crane main beam 3; in this embodiment, four transverse railings 2 are used, and rectangular plug-ins 5 are provided at the bottom of the front and rear ends of each transverse railing 2. The transverse railings 2 are detachably plugged in and installed between two adjacent vertical poles 1 on both sides of the bottom of the cable crane main beam 3 through the sockets 4 and the plug-ins 5.

[0018] The cable crane operation area guardrail is formed by arranging poles 1 on both sides of the front, middle and rear bottom of the cable crane main beam 3, and then installing transverse railings 2 between two adjacent poles 1 on both sides of the bottom of the cable crane main beam 3. The poles 1 and transverse railings 2 form a guardrail structure to play an isolation and protection role, preventing personnel from mistakenly entering the operation area during the operation of the rope arrangement mechanism, thereby avoiding safety accidents. In addition, since the transverse railings 2 and the poles 1 of the cable crane operation area guardrail are detachably connected through the socket 4 and the plug 5, it is convenient for personnel to perform maintenance and construction when the rope arrangement mechanism on the belly of the cable crane is being repaired.

[0019] Further, as a preferred technical solution of this embodiment, Figure 1 and Figure 2 As shown, in this embodiment, a reflective strip 6 is pasted on the outer end surface of the horizontal railing 2, and the reflective strip 6 serves as a warning, which is convenient for night shift personnel to observe the warning.

[0020] Furthermore, as a preferred technical solution of this embodiment, Figure 1 As shown, the cable crane operation area guardrail also includes a protective net 7, which is a rectangular mesh structure and is arranged on both sides of the cable crane belly chain device 8. The protective net 7 is detachably connected to the cable crane main beam 3, the vertical pole 1 and the horizontal railing 2 by bolts or stainless steel tie. The protective net 7 prevents the chain device from breaking suddenly during high-speed operation, and the chain flies out and injures people.
