The application provides a pear head removing device and a pear head removing method. The pear head removing device comprises a body, a blade driving device and a first blade. The body comprises a first accommodating groove for accommodating a pear head and a steel wire rope. The blade driving device is fixed to the body. The first blade is connected with the blade driving device, and the blade driving device is used for driving the first blade to extend and retract. When the first blade extends, the steel wire rope can be cut. The application solves the safety risk that the existing removing device is easy to cause fire and scald the operator.

This utility model discloses a mobile trolley for loading pear-shaped wire rope slings, including a base, a support platform on top of the base, and positioning saddles on the support platform. The base has several casters with brakes at its bottom. A lifting device connected to the bottom of the support platform and used to control the lifting and lowering of the support platform is fixed to the base. Several positioning saddles are evenly distributed on the support platform. A baffle plate is provided around the outer edge of the support platform, and a push handle is connected to the baffle plate. Each positioning saddle has a V-shaped groove for placing the pear-shaped rope sling. Heat-resistant cushioning pads are provided at both ends of the inner walls of the V-shaped groove and at the bottom of the groove where it contacts the pear-shaped rope sling. This trolley allows for convenient and flexible handling of pear-shaped rope slings, and can handle more than three at a time. The support platform has adjustable lifting capabilities to accommodate various sizes of pear-shaped rope slings, facilitating the lifting and rotating device to retrieve the pear-shaped rope slings.

The utility model discloses a pear-shaped bridge tower construction support convenient to disassemble, and relates to the field of supports for formworks in bridge tower construction, the pear-shaped bridge tower construction support convenient to disassemble comprises four fixed supports, the two ends of each fixed support are connected with sliding supports through adjusting mechanisms, a corner connector is arranged between every two sliding supports which are distributed in a right-angle mode, and the corner connector is connected with the sliding supports through adjusting mechanisms. And abutting blocks abutting against the corner connectors are formed on the outer sides of the ends, away from the fixed supports, of the sliding supports, the adjacent corner connectors are connected through fastening mechanisms, and limiting mechanisms connected with the steel formworks are distributed on the outer sides of the fixed supports. By arranging the limiting mechanism and the sliding mechanism, in the mounting and dismounting process, the limiting mechanism can limit the fixing supports, the position of the sliding support can be adjusted through the sliding mechanism, fixing can be achieved conveniently, in the dismounting process, the four fixing supports and the sliding support cannot fall off suddenly, and the fixing effect is good. And relatively convenient disassembly can be carried out.
