The utility model discloses a compact special electric rope reversing machine of vehicle-mounted well repairing machine relates to rope reversing machine technical field, the utility model discloses a base and with the first support, second support and third support of base top fixed connection are equipped with start -stop mechanism between the first support and second support, be equipped with speed reduction mechanism between second support and third support, the utility model discloses a rotating shaft is set to rotate the limiting rod, and the limiting rod is removed to the limit of connecting plate, and the handle is pulled to the direction of the second pivot of connecting plate, and the connecting plate will drive the second pivot to slide in the limiting frame, and the second pivot will also drive the limiting ring to slide in the rotary drum, thereby making the second pivot and the slot on the limiting shaft separate, reaches the rotation of the rope drum can be controlled at any time, can effectively avoid the sustained movement of the rope, prevents the rope to appear slack, twisted or uneven state, keeps the effect of wellhead equipment and operating tool stability.

This utility model discloses a high-stability mechanical equipment lifting and installation mechanism, including a lifting device slidably installed outside a supporting beam. A motor-driven drive roller is rotatably installed inside the lifting device. A lifting steel rope driven by an internal winch is installed below the lifting device, and a lifting plate is fixedly installed at the bottom end of the lifting steel rope. Fixed hooks are installed at both ends of the lifting plate. A horizontally arranged stabilizing plate is installed below the lifting device, and the lifting steel rope slides through the stabilizing plate. This high-stability mechanical equipment lifting and installation mechanism utilizes the winch inside the lifting device to drive the extension and retraction of the lifting steel rope, thereby achieving the purpose of lifting goods. After lifting, when the lifting device moves horizontally, the lifting steel rope, under the inertia of the goods below, causes relative displacement between the stabilizing plate and the lifting device. At this time, the connecting rod compresses the shock-absorbing spring, which, in conjunction with the damper, achieves the purpose of shock absorption, thereby reducing the swaying of the goods below.
