And a balance block is fixed at one end of the strip-shaped frame 11, which is far away from the motor of the screw 14, and the weight of the balance block is consistent with that of the motor of the screw 14 and is used for balancing the weight at two ends. The whole strip-shaped frame 11 is of a structure with balanced and symmetrical left and right weight.
The bottom of slip table 16 is passed through welded fastening and is had the bearing plate 17 of rectangular shape, the top and the 16 bottom welding of slip table of the central authorities of bearing plate 17, the length direction of bearing plate 17 is unanimous with the length direction of linear slide rail, the both ends of bearing plate 17 are equipped with the hanging hole respectively, it has buckle 18 to run through in the hanging hole, it has hoist cable 19 to collude the cooperation in the buckle 18, hoist cable 19 can be wire rope, also can be metal chain, not confine to this example, can adopt any rope form instrument that has enough bearing effect, realizes tying up fixedly to bar-shaped building materials such as reinforcing bar.
When the binding device is used, the rod-shaped building materials are bundled and fixed at the positions which are symmetrical relative to the center by adopting the conventional common binding method, and then are lifted.
The bearing plate 17 has the main function of providing allowance for feeding in two directions, and the side building materials are translated through the left-right sliding of the central sliding table 16, so that the gravity center of the building materials can be deviated and sent to the position near a falling point.
The working mode of the device is as follows:
the weight box 5 is arranged in the center of the guide frame 2, the sliding table 16 is also arranged in the center of the guide frame 2, and the device is in a self-balancing state under the condition that lifting objects are not added;
based on the guide frame 2 of this device and the subassembly of fixed mounting on guide frame 2 to and bar frame 11 and the subassembly of fixed mounting on bar frame 11 are the balanced subassembly of counter weight about relative length direction, so when slip table 16 and counter weight frame are located central authorities, the counter weight is balanced about whole device keeps, and about after the hook hanger 1 lifts by crane is balanced state.
The hoisting equipment hoists the device to a building material stacking position based on the hanger 1;
through the retaining rings 18 at the two ends of the bearing plate 17, the sling 19 or other tools are combined to bundle and fix the rod-shaped building materials such as the reinforcing steel bars;
hoisting equipment lifts, the device fixed with the building materials for side loading is lifted to a target position,
one end of the rod-shaped building material close to the building body is close to the floor between the target positions;
judging whether hovering is needed or not according to the situation, and waiting for the building materials to be stable;
after the building material is in a stable hovering state, a walking motor and a screw rod 14 motor are started simultaneously, the screw rod 14 motor drives the screw rod 14 to rotate so that a bearing plate 17 can translate towards one end of a building body, the walking motor drives the walking gear 10 to rotate so that the weight box 5 can translate in the reverse direction, the building material translation enables the gravity center of the building material to deviate from the weight bias caused by the central hoisting point, the weight bias is offset through the reverse movement of the weight box 5, and therefore the building material can be conveyed between floors without obvious loss of balance;
based on the fact that the building materials can be fed in a mode of deviating from the lifting points, workers do not need to receive the building materials at the edges of the floors, but wait for the building materials to be partially fed between the floors and hover stably in the areas far away from the falling points, and then approach the building materials to receive and unload the building materials.
Through the device, after the building materials are translated and deviate from the lifting points, the deviation of the balance weights is compensated through the reverse translation of the weight box 5, so that the influence of the deviation of the building materials from the lifting points is balanced, and the gravity center position of the building materials can be deep between floors as far as possible after the building materials are lifted to the height of a target area. The most important effect is that the building material falls and automatically goes deep, the link of active receiving of workers is replaced, the building material is not dragged and received by the workers any more, the building material is lifted and laid, the falling point work is mainly carried out by the lifting link, the work difficulty and the labor intensity of the workers in the receiving area are greatly reduced, the workers do not need to risk the falling point work, and the violation hidden danger of the link is fundamentally solved.
