Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further:
As shown in Fig. 1 to 2, the preferred embodiment that the utility model provides.
Overload crane restraint device, can be used in hoisting crane and sling in the process of weight and moving heavy object.
Overload crane restraint device, comprise bearing seat 101, base 102, pressing plate 103 and pressure sensor 1031, wherein, bearing seat 101 supports the drum shaft two ends that hoist, and base 102 matches with bearing seat 101, pressing plate 103 is arranged on bearing seat 101, pressure sensor 1031 is arranged on pressing plate 103, is formed with groove bottom bearing seat 101, and pressing plate 103 is embedded in groove, pressure sensor 1031 is formed with strain-gauge 1032, pressing plate 103 lower end contacts with base 102 upper surface.
When hoisting crane slings weight, the pressure that reel is applied to pressure sensor 1031 increases, and the pressure that strain-gauge 1032 is subject to increases, and can adopt different strain-gaugies 1032, thus can judge whether the weight that hoisting crane is sling overloads according to different suspension hooks.
Overload crane restraint device, adopts General design, needs specific customization to change standardized structure into existing overload limiting device of lifting weight, novel structure is unique, advantages of simple, easily produces, easy to operate, take off data is accurate, not fragile, long service life, safe and reliable, easy to use, effective.
In order to avoid loosening of pressing plate, cause result of a measurement inaccurate, pressing plate is formed with mounting hole, be formed with lower mounting hole in groove, upper mounting hole and lower mounting hole are bolted.
Overload crane restraint device also comprises control element 104 and control device 105, wherein, control device 105 and control element 104 are electrically connected, strain-gauge logical 1032 is crossed wireless mode and is connected with control element 104, control element 104 is arranged on base 102 leading flank, control device 105 and control element 104 are wirelessly electrically connected, the change of strain-gauge 1032 is received by control element 104, read-out 1051 shows weight and overload condition, user can manipulate the operating mode of the hoisting heavy of hoisting crane indirectly by control device 105, advantages of simple, easy production, easy to operate.
