Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention will be further described in detail.
Embodiment 1:
As shown in Figure 1, a kind of device ensureing suspension hook soft landing and overload alarm thereof, comprises the symmetrical unit of two covers, and the unit of this two covers symmetry is connected by upper and lower two orienting sleeves 104, and is fixed in driving respectively by upper and lower two adapter plates 105; Described unit comprises: expansion link 101,2 anticreep pilot bars 102, elastomeric element 103, flange 110 and adjustable screw 111; One end of described expansion link 101 is provided with circular hole, passes for steel rope 109, and described adjustable screw 111 is connected with the other end of expansion link 101; Described flange 110 is enclosed within expansion link 101; Described elastomeric element 103 between orienting sleeve 104 and flange 110, for adjustable telescopic rod 101; 2 anticreep pilot bars 102 are each passed through the two ends of two orienting sleeves 104 and flange 110, for limiting the sliding position of flange 110; Described orienting sleeve 104 is provided with control circui subelement, for controlling suspension hook motor.
Preferably, described elastomeric element 103 is spring.
The described control circui subelement that comprises comprises: 2 soft landing limit switches, 106,2 overload limit switches 107 and operating selection switch 108, wherein, 2 soft landing limit switches 106 are arranged on bottom orienting sleeve 104 and the top of lower orienting sleeve 104 respectively, and 4 soft landing limit switches 106 of whole device are connected in series; Then be connected with operating selection switch 108, suspension hook motor respectively; 2 overload limit switches 107 are arranged on bottom orienting sleeve 104 and the top of lower orienting sleeve 104 respectively, and 4 overload limit switches 107 of whole device are connected in series; Then be connected with operating selection switch 108, suspension hook motor respectively; Described operating selection switch 108 is for controlling the power supply of soft landing limit switch 106 and overload limit switch 107.
