Description

Damping device on cable dish Technical Field The utility model relates to the field of mechanical structures, in particular to a damping device on a cable drum. Background The movable cable tray is used for winding a power line, a signal line and a data transmission line, two ends of the cable are connected with matched connectors for long-distance and outdoor use, and the movable cable tray can be repeatedly wound and unwound and is convenient to carry. In general, the cable reel is used for adjusting the cable winding and unwinding speed of the cable through the damping device when the cable reel is wound and unwound, so that the cable winding and knotting can be avoided, and the cable can be used rapidly. The general cable drum assembly winds the undamped device speed governing of cable, and unwrapping wire cable speed is different, leads to the unwrapping wire too fast, and easy winding is tied off, seriously influences the cable and uses and reduces cable life. The prior application (2025205373774) describes a damping device which can solve the above problems, but in the practical application process, there is a special cable tray, and the damping device cannot be arranged according to the structure in the application scheme due to space limitation, so that the damping structure needs to be considered from other angles. Disclosure of utility model The utility model aims to improve a damping structure on the basis of the prior art, so that damping under the condition of meeting some space limitations is realized. The damping device on the cable tray comprises a damping bracket arranged on the cable tray bracket, and a damping elastic piece arranged on the damping bracket, wherein one end of the damping elastic piece is in elastic contact with the surface of the cable tray. In the above technical scheme, the damping elastic piece comprises a sleeve, a pull rod and a spring, wherein the pull rod and the spring are arranged in the sleeve, and a damping fin is arranged at one end of the pull rod penetrating through the sleeve. In the technical scheme, a baffle is arranged on the sleeve, and the spring is arranged between the baffle and the damping bracket. In the technical scheme, a limiting step is arranged in the sleeve, the baffle is arranged on the limiting step, and the pull rod can penetrate through the baffle and drive the baffle to move. In the technical scheme, the end cap is arranged at the other end of the pull rod penetrating through the sleeve, and the locking pin is arranged at the joint of the pull rod and the end cap. In the technical scheme, the clamping groove is formed in the end face of the sleeve, and the locking pin can slide out of the sleeve and then be buckled with the clamping groove. In the above technical scheme, the sleeve is axially provided with a groove, and the locking pin can slide along the groove and extend into or out of the sleeve. In the technical scheme, the locking pin on the pull rod can drive the baffle to move. In summary, due to the adoption of the technical scheme, the beneficial effects of the utility model are as follows: The damping device solves the problem that under the condition of limited space, particularly under the condition of limited space between the cable support and the cable drum, the damping operation is carried out on the cable drum, the control of the rotating speed of the cable drum is realized, a certain damping effect is realized in the paying-off process, jolt and vibration can be effectively reduced, the comfort of operators is improved, and the damping device is suitable for long-time field operation.
