4results about How to "Improve lifting safety" patented technology

This utility model discloses a positioning device for processing offshore wind turbine towers, including a lifting mechanism. The lifting mechanism includes a support plate, multiple reinforcing blocks embedded on both sides of the support plate, outriggers rotatably connected to the reinforcing blocks, casters connected to the bottom ends of the outriggers, and multiple bidirectional electric push rods embedded in the bottom of the support plate. The bidirectional electric push rods are movably connected between two opposing outriggers. In this utility model, the movable ends of the multiple bidirectional electric push rods are controlled to retract, and then the outriggers, with the assistance of the casters, retract towards the center of the support plate, thereby raising the support plate so that it can be positioned to one side of the wind turbine tower. Then, the movable ends of the multiple bidirectional electric push rods are controlled to extend, and under the same principle, the multiple outriggers lower the support plate. After the bottom of the support plate touches the ground, the wind turbine tower is placed on top of the support plate using external hoisting equipment. The wind turbine tower is lifted and lowered in place, improving the safety of hoisting.

The utility model discloses a mechanical clamp for marble processing relates to marble hoist clamp technical field, including hoist clamp subassembly, locking subassembly, locking subassembly is used for the clamping state of hoist clamp subassembly is located. The utility model discloses a locking subassembly is set up, when hoist clamp subassembly is clamped to marble board, hoists, ratchet wheel card seat can realize the one -way locking of the inclined ratchet plate, so, when marble board is shifted to the specified position and is slowly put down, marble board bottom and object contact, and the lifting equipment's lifting rope is still in relaxation, and extrusion seat keeps with the lifting seat and keeps height relative invariable under the mutual locking of the inclined ratchet plate, ratchet wheel card seat, namely, moving the clamping plate and fixed clamping plate keep the steady clamping state of marble board at this moment, need to release the clamping of hoist clamp subassembly to marble board, just need to manually pull the pull rope and can, effectively improve marble board hoisting safety.

The utility model relates to the technical field of steel plate conveying, and specifically discloses a laser cutting machine steel plate to be cut conveyor, which comprises a base, the top of the base is provided with a support truss, the support truss is slidably matched with the base, the top of the support truss is provided with a lifting plate driven by a lifting mechanism, a plurality of sliding grooves are equidistantly arranged at the bottom of the lifting plate, the sliding grooves are horizontally arranged, sliding blocks are slidably arranged in the sliding grooves, an electric permanent magnetic adsorption mechanism is arranged at the bottom of each sliding block, clamping blocks are vertically arranged at the two ends of each sliding groove, the two clamping blocks are oppositely arranged, a driving moving mechanism is arranged in matching with each clamping block, and a movable block for limiting the steel plate body is slidably arranged on the clamping block. The utility model can effectively improve the hoisting safety of the steel plate body, realize stable conveying effect, and be flexibly adapted to steel plate bodies of various specifications.

The application belongs to the technical field of building construction, and particularly relates to a precast beam hoisting and transporting device, which comprises a hoisting beam, a sling, a first half sliding sleeve, a second half sliding sleeve and a reset spring. Before the precast beam is hoisted and transported, the reset spring at both ends of the inner cavity is pushed to make the first half sliding sleeve and the second half sliding sleeve be at the central position of the inner cavity, so that the length of both ends of the sling is always consistent. During the hoisting and transporting of the precast beam, when the precast beam is slightly inclined, the sling drives the first half sliding sleeve and the second half sliding sleeve to slide along the inner cavity to the side, the reset spring at the side is compressed, and the reset spring at the other side is stretched. The elastic force generated by the reset springs at both sides can make the first half sliding sleeve and the second half sliding sleeve reset to the central position of the inner cavity, drive the height of both ends of the sling to return to the horizontal state, thereby adjusting and restoring the precast beam to the horizontal state, and then the stability and safety of the hoisting and transporting of the precast beam are improved.
