Description
Technical Field
The utility model relates to a jack-up technical field, concretely relates to hoisting equipment prevents that the hoisting rope from surpassing the device of design bearing capacity when adopting the hoisting rope to lift by crane the heavy object.
Background
When the cable crane is used for hoisting heavy objects, the bearing capacity of the hoisting rope is generally designed to be safe, and the appropriate hoisting rope is selected according to the weight of the hoisted objects. During specific construction, if the weight of the hoisting object is overweight or the hoisting object is blocked or collided, the stress of the hoisting rope is possibly over-limited, but the hoisting rope is difficult to find in time, so that great potential safety hazard exists.
Disclosure of Invention
The utility model aims at providing a cable crane overweight controlling means of load rope can promptly stop when jack-up thing weight surpasss the design value of load rope, guarantees the safety of construction.
The technical scheme of the utility model as follows:
the utility model provides a cable crane hoisting rope overweight controlling means which characterized in that: the spring support comprises a top plate, wherein side plates perpendicular to the top plate are respectively welded on two sides of the top plate, a through hole is formed in the middle of the top plate, a bearing rod is movably inserted in the through hole, the upper end of the bearing rod is arranged above the top plate and welded with an upper lug plate, the lower end of the bearing rod is arranged below the top plate and welded with a limiting plate, a bearing plate is welded on the bearing rod between the limiting plate and the top plate, a spring is sleeved on the bearing rod between the bearing plate and the top plate, the upper end of the spring is supported on the bottom surface of the top plate, and the lower end of the spring; a certain distance is reserved between the limiting plate and the bearing plate; a sensor is arranged on one side plate and provided with a touch sensing head, and the sensing head is positioned between the limiting plate and the bearing plate; the lower ends of the two side plates are welded with a lower ear plate; and hoisting rope connecting holes are formed in the upper ear plate and the lower ear plate.
The utility model is used for during the construction, connect between two hoisting ropes, when hoisting object weight surpassed hoisting rope safe value, limiting plate touch sensor can in time discover overweight phenomenon and make cable crane emergency shutdown, avoids the hoisting rope to break because of overweight emergence, the effectual production that reduces the cable crane accident, very big guarantee construction safety. The utility model discloses not only be applicable to the cable and hang the construction, also be applicable to other constructions that adopt the hoisting rope to lift by crane the heavy object.

Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
As shown in fig. 1, the utility model comprises a top plate 1, two sides of the top plate are respectively welded with a side plate 2 perpendicular to the top plate, a through hole is arranged in the middle of the top plate, a bearing rod 3 is movably inserted in the through hole, the upper end of the bearing rod 3 is protruded above the top plate and welded with an upper ear plate 4, the lower end of the bearing rod is arranged below the top plate and welded with a limiting plate 5, a bearing plate 6 is welded between the limiting plate and the top plate on the bearing rod, a spring 7 is sleeved between the bearing plate and the top plate on the bearing rod, the upper end of the spring 7 is supported on the bottom surface of the top plate 1, and the lower end is supported on the top; a certain distance is reserved between the limiting plate 5 and the bearing plate 6; a sensor 8 is arranged on one side plate 2, the sensor is provided with a touch type induction head 9, and the induction head 9 is positioned between the limiting plate 5 and the bearing plate 6; the lower ends of the two side plates are welded with a lower ear plate 10; and hoisting rope connecting holes are formed in the upper ear plate and the lower ear plate.
The utility model discloses during the implementation, can all set up limiting plate 5 and bearing plate 6 into the annular, and coaxial with the bearing bar.
The utility model discloses when the preparation, the pressure that the compressive capacity of pretesting the spring corresponds, corresponds the design safe value of jack-up rope with the maximum allowable compressive capacity of spring, and the maximum allowable compressive capacity of spring is corresponded with the distance of limiting plate and sensor inductive head.
The utility model discloses during the use, a jack-up rope is connected respectively to upper and lower otic placode, and the jack-up rope of upper otic placode is connected the cable and is hung, and the jack-up rope of lower otic placode is connected and is hung heavy thing, with the control system that the signal output line connection cable of sensor hung. When the cable is hoisted, the spring is compressed, the bearing rod moves upwards, when the limiting plate is in contact with the sensor sensing head, the situation that the bearing capacity of the hoisting rope reaches a safety value is indicated, the sensor sends a sensing signal to the control system, and the control system can emergently stop the cable crane to avoid the hoisting rope from being broken due to overweight.
