Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments.
Embodiment one:
the tool for winding and unwinding the steel wire rope of the heavy crane comprises a steel wire rope winding drum 1 and roller frames, wherein the roller frames are symmetrically arranged at the bottoms of two ends of the steel wire rope winding drum, the steel wire rope winding drum 1 is arranged on the roller frames at two sides in a rolling way, and the roller frames are used as a rotation driving mechanism of the steel wire rope winding drum 1; the steel wire rope winding drum is characterized in that a steel tube shaft 3 penetrates into a shaft hole of the steel wire rope winding drum, weight structures 4 are hung at two ends of the steel tube shaft 3, and the weight structures 4 are of a combined adjustable structure and are used for meeting the steel wire rope winding drums of different specifications. As shown in fig. 8, the weight structure 4 is provided with two plugs 38 protruding from the upper end surface of a rectangular parallelepiped, the lower end surface is provided with a latch 39 matching with the plugs 38 in a concave manner, and the weight structure 4 is clamped into the latch 39 by a steel cable and is suspended on the steel tube shaft 3. The weights are combined modules, and the modules with different numbers are combined, so that the tool has different dead weights. The modules have 1 ton, 2 tons and 3 tons, and all have dovetail grooves with the same specification, so that the modules have interchangeability. Through this kind of structure, can satisfy the wire rope reel of different specifications and use, also increased the steadiness of whole frock simultaneously.
The steel cable should be ensured to pull the weight a small distance away from the ground. Through theoretical calculation, the dead weight of the rope collecting device is increased, the friction force between the roller frame and the ground can be increased, and the dangerous situation that the roller frame is pulled by traction force can be avoided.
The two roller frames are of self-powered structures commonly used in the prior art, as shown in fig. 1, each roller frame comprises a longitudinal beam, two ends of each longitudinal beam are hinged with V-shaped pincer-shaped brackets 7, two ends of each pincer-shaped bracket 7 are rotatably connected with each other and provided with supporting wheels 8, each supporting wheel 8 is in rolling connection with a steel wire rope reel, two groups of roller frames are symmetrically arranged at the bottom of each steel wire rope reel, the two groups of roller frames are respectively supported at two ends of each steel wire rope reel 1, the supporting wheels 8 are driven to rotate by utilizing the power of the automatic belt of each roller frame, and further the steel wire rope reel 1 is controlled to rotate so as to realize winding or unwinding of the steel wire rope, and the bottom of each weight structure 4 is suspended, and a gap is reserved between each supporting wheel and a deck so that all weight acts on the steel wire rope reel; the steel tube shaft 3 and the shaft hole of the steel wire rope winding drum have a larger gap, so that the steel tube shaft 3 does not rotate along with the winding drum; a larger gap is reserved between the steel tube shaft 3 and the steel cable sleeve of the weight hanging steel cable, and the steel cable sleeve does not rotate along with the steel tube when in use; the roller frame and the deck can be welded without welding, so that the device has better maneuvering characteristics, and the device prevents the whole set of tool from moving on the deck by virtue of friction force generated by the dead weight of the whole set of tool.
Specifically, for example, when 450T heavy hoist receives the rope, accessible steel cable is connected weight (2.2T) and steel pipe axle 3 (phi 140 mm) to increase the dead weight of wire rope reel and gyro wheel frame and then increase the frictional force with the deck, thereby avoid taking place following dangerous condition:
(1) The traction force of the wire winding rope pulls the winding drum away from the roller frame. This is due to the fact that the moment generated by the horizontal traction on the reel on the fulcrum on the roller frame is greater than the anti-overturning moment generated by the dead weight of the reel on the fulcrum. Therefore, the dead weight of the winding drum is increased, the anti-overturning moment can be increased, and the dangerous condition that the winding drum is pulled away from the roller frame by traction force can be avoided.
(2) The traction force of the wire winding rope pulls the roller frame at the bottom of the winding drum, so that the whole wire winding device translates on the ground. This is due to the fact that the horizontal traction on the reel is greater than the friction between the roller frame and the ground. Therefore, the dead weight of the rope collecting device is increased, the friction force between the roller frame and the ground can be increased, and the dangerous situation that the roller frame is pulled by traction force can be avoided.
When the method is adopted for rope winding, the steel cable is ensured to pull the weight away from the ground for a small distance. It should be noted that by theoretical calculation, the maximum traction force of the initially received wire rope is 1T. Therefore, the friction force to pull the roller frame against the traction should be greater than 1T. Considering that the friction coefficient between the roller frame and the ground is 0.2, the dead weight of the whole rope collecting device is larger than 5T. So consider hanging a 2.2T weight at each end of the spool.
