Embodiment Construction

[0018] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described here are only used to explain the present invention, not to limit the present invention.

[0019] Such as figure 1 , figure 2 , image 3 As shown in FIG. 1 , a schematic diagram of an installation type of an infinitely adjustable tensioning device 100 provided by the present invention in an oblique pendulum suspension type under a mine.

[0020] figure 1 , figure 2 , image 3 Among them, an infinitely adjustable tensioning device 100 is fixedly connected to the mine wall 300 through the lower anchor arm 400 and bolts 500, and the steel wire rope 19 of the infinitely adjustable tensioning device 100 passes through the two-ear wedge-shaped clamp 20 and the antenna wire 200. connect.

Abstract

The invention belongs to the technical field of mine heavy-load trolley bus power supply line anchorage tensioning devices, and provides a stepless adjustment tensioning device 100 which comprises a locking pin 1, a locking plate 2, a locking bolt 3, a left supporting plate 4, an involute wheel 5, an installation base plate 6, a barrel body 7, a connecting shaft 8, a worm 9, a side plate 10, a bearing 11, a sealing ring 12, a main shaft 13, a bearing 14, a bearing cap 15, a right supporting plate 16, a worm gear 17, a flat spiral spring 18, a steel wire rope 19, a double-lug wedge-shaped wire clamp 20 and the like. When contact lines 200 of an overhead line system of a trolley bus are contracted and / or expanded, the flat spiral spring 18 can be automatically wound up or released, therefore, constant tension is kept on the contact lines 200 through the synchronization action of the involute wheel 5, meanwhile, stepless adjustment can be carried out on the tension of the contact lines 200, and the better operation effect is achieved.

Description

technical field [0001] The invention relates to the technical field of an anchor tensioning device for a mine heavy-duty trolleybus power supply line. In particular, it relates to an infinitely adjustable tensioning device. Background technique [0002] Trolley bus is a kind of public transportation that uses electric power to run on the road without relying on fixed rails. Trolley bus is powered by catenary and driven by electric motor. Generally, trolleybuses will lose power if their collector poles go off-line; while trolleybuses equipped with power batteries, supercapacitors or diesel generators with dual power sources can realize off-line driving on road sections without catenary. [0003] In order to ensure that the contact line changes with temperature and curve radius so as to ensure the tension of the contact line, the catenary compensation of the existing urban passenger trolleybus adopts the oblique pendulum suspension type, which is arranged in a "zigzag" shape....
