Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

Embodiment 1, please refer to fig. 1 and 2, a vertical take-up and pay-off cart for an electric power transmission line system; comprises a bottom support member 1 for realizing bottom support; the bearing support member 2 is used for supporting the wire disc when the wire disc is erected; the rotary supporting component 3 is used as a rotary carrier to ensure that the bearing supporting component drives the wire coil to rotate together, the lower end face of an outer ring 3-1 of the rotary supporting component is connected with the bottom supporting component, and the upper end face of an inner ring 3-2 of the rotary supporting component is connected with the bearing supporting component through a connecting column 2-3; and a mandrel coaxial with the rotary supporting member is arranged on the upper end surface of the bearing supporting member. The mandrel is matched with the inner hole of the wire spool of the wire coil; if customized production is adopted, the mandrel and the spool can be processed into the spline fit which is mutually matched when being processed, and the constraint of the mandrel and the spool is facilitated.

Preferably, the bottom support member 1 adopts a support wheel carrier structure, and the weight of the bottom support member is reduced on the basis of ensuring enough support strength by adopting the structure.

Preferably, the bearing support member 2 comprises a rotary disc 2-1 connected with an inner ring of the rotary support member, an outer circular shaft of the rotary disc is provided with a rotary support wheel frame 2-2, the structure is adopted to reduce the weight of the bearing support member on the basis of ensuring enough support strength, in addition, the support wheel frame is detachably connected with the bottom support disc, and when the support wheel frame is deformed due to overlarge stress, the support wheel frame can be independently replaced, so that the comprehensive use cost is reduced.

In embodiment 2, referring to fig. 3, on the basis of embodiment 1, a guide cone 4-1 is disposed at an upper end of the mandrel, so as to improve the efficiency of inserting the mandrel into the center of the bobbin and have an automatic alignment function.

In embodiment 3, referring to fig. 4, on the basis of embodiment 2, a tapered expanding sleeve 6 is fixedly installed at the root of the mandrel, so as to ensure the fit between the mandrel and the central hole of the bobbin. The surface of the conical expansion sleeve is provided with grains 6-1 for increasing the friction force, and the grains are arranged along the normal direction of the conical surface.

In embodiment 4, referring to fig. 5, based on embodiment 3, preferably, a limiting column 5 is installed between the bottom supporting plate of the bottom supporting member and the rotating plate supporting the supporting member, and a safety rotating gap is provided between the limiting column and the upper rotating plate.
