Problems solved by technology

At present, domestic constant tension and small tension stringing equipment cannot operate normally on tram lines due to the small radius of the ballast bed and the curve, and the operation of the tension stringing device is complicated, and there are many links to control the tension, requiring a large number of personnel to complete the erection line, slow pay-off efficiency

Embodiment Construction

[0015] As shown in the figure, the small tension wire racking device is provided with a wire reel frame 1 for carrying wire reels. The wire reel frame 1 is a frame formed by connecting channel steel to support other components. A bearing spool 2 and a tension adjustment mechanism are provided. The bearing spool 2 is rotatably arranged on the spool frame 1, and is inserted into the spool hole to drive the spool to rotate. The bearing spool 2 is arranged horizontally, and its two ends are detachably set to the spool. On the frame on both sides of the top of the rack 1, when the spool is installed, remove the bearing spool 2, insert it into the center hole of the spool, install the spool on the bearing spool 2, and install the fixing rod on the bearing spool 2 perpendicular to its axial direction 9. It is clamped on one side of the spool, and the other side of the spool is clamped by the clamp set on the carrying spool 2 to avoid the spool from swinging left and right during the w...

Abstract

A small tension wire-reeling device belongs to the technical field of contact wire-reeling equipment for modern trams, and is provided with a wire reel frame for carrying wire reels. The tension adjustment mechanism includes a rotating wheel, a brake pad for adjusting the rotation speed of the rotating wheel, and a tension controller for controlling the braking resistance of the brake pad. The axle of the rotating wheel is connected to one end of the bearing spool and rotates coaxially. Turn the disc, the threaded rod, the connecting link and the transmission rod. By turning the rotary disc, the threaded rod can rotate upward or downward on the wire frame, so as to use the lever action of the transmission rod to tighten or loosen the brake pads to adjust the rotating wheel. The rotation speed of the spool can be adjusted to realize the adjustment of the rotation speed of the spool. The present invention can ensure continuous tension for the contact wire during the wire erection process, and can adjust the erection tension of the contact wire at any time.

Description

technical field [0001] The invention belongs to the technical field of contact wire stringing equipment for modern trams, and particularly relates to a small tension stringing device. Background technique [0002] Most modern tram lines are located in dense factory areas, living areas and scenic spots. The minimum design curve radius is 30 meters. The rails are built-in grooved rails with the same height as the rail surface and the ground. The rail spacing is 1435mm. . In order to ensure the quality of the contact wire erection, the contact wire erection should ensure that the contact wire does not have serious defects such as twisted surface, bending and ground friction, and the use of manual wiring is prohibited. In order to ensure that the leads do not drag the ground and rub against the ground to damage the leads during the erection process and ensure the quality of the lead installation, it is necessary to apply tension to the leads. At present, the domestic constant ...
