Description

Technical Field

[0001] The utility model relates to the field of cables, in particular to a cable tension control device. Background Art

[0002] A cable is a device for transmitting electrical energy or signals, usually composed of several or several groups of wires, usually a rope-like cable formed by twisting several or several groups of wires (at least two in each group). Each group of wires is insulated from each other and often twisted around a center. The entire outside is covered with a highly insulating covering. The cable has the characteristics of being powered inside and insulated outside.

[0003] Cables need to be installed and arranged when transmitting electric energy. In areas with colder winters, cables expand and contract significantly due to heat and cold, so cables need to be reserved when arranging them. These cables deform significantly when the temperature changes, and require auxiliary tightening devices. The traditional tightening method is semi-permanent and needs to be operated again when loosening. For this reason, a cable tension control device is proposed. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0026] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0027] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0028] First, the cable passes through the device housing 1 and the circular hole of the winding wheel 13. When the cable is relatively loose, first start the tightening motor 14 to drive the tightening gear 15 to rotate, so that the tightening ring 16 rotates to push the clamping block 172 to slide inside the positioning ring 171 to clamp the cable, and start the double-axis motor 10 to drive the double-axis threaded rods 11 at both ends to rotate, so that the two movable sleeves 12 drive the winding wheels 13 to approach each other, and at the same time start the incoming line motor 3 to drive the power wheel 4 to rotate, and the pushing spring 6 pushes the pushing shell 5, so that the clamping wheel 8 clamps the cable, so that the cable shrinks to the inside of the housing 1 to maintain its tension. At the same time, when the winding wheel 13 moves, the ratchet gear 2 1 rotates on the surface of the ratchet plate 20, so that the winding wheel 13 close to the power wheel 4 rotates, the cable is wound on the surface, and the winding wheel 13 winds the cable. When the cable needs to be tightened further, the tightening motor 14 is started to drive the tightening mechanism 17 to loosen the cable, so that the dual-axis motor 10 drives the dual-axis threaded rod 11 to rotate to reset the winding wheel 13, and the cable is clamped again for repeated tightening. When the cable needs to be loosened, the traverse motor 18 is started to drive the traverse shaft 19 to rotate, so that the ratchet plate 20 is disengaged from the ratchet gear 21, so that the ratchet gear 21 can flip and loosen the cable wound by the winding wheel 13, and the winding wheel 13 can push the ratchet plate 20 close to the ratchet gear 21 to control and slow down the release speed.

[0029] In the related art, cables need to be reserved when arranging the cables, and these cables deform significantly when the temperature changes, and need to be tightened with an auxiliary device. The traditional tightening method is semi-permanent and needs to be operated again when loosening.
