Before the utility model, traditional straight arm type high-altitude operation platform rarely has testing device for wire ropes, and high-altitude operation platform is under long-time running state, steel rope can produce and be elongated, loosening or disconnected hidden danger of restricting, easily produce safety misadventure, in order to solve above-mentioned hidden danger, need supporting a set of safety device.
In addition, the safety requirements in GB25849-2010 " Mobile lifting workplatform design calculation, safety requirements and test method " has also proposed corresponding requirements to wire rope gearing system safety devices.
The major defect of prior art: steel wire rope looseness or fracture time do not have signal transmitter, or there is the defects such as complex structure, installation requirement are high, poor reliability.Use the approach switch structurally can be simpler, but while using, easily cause false alarm and damage under the harsies environment such as shipyard shot-peening operation.
Utility model content
The purpose of this utility model is to overcome above shortcomings in prior art, and a kind of simple in structure, reasonable in design, easy for installation, dependable performance, the testing device for wire ropes timely of reporting to the police are provided.
The technical scheme in the invention for solving the above technical problem is: this testing device for wire ropes, comprise pilot bar and for the flexible steel rope of working arm, described pilot bar is welded on working arm, described steel rope is got rid of tightly by jam nut, characterized by further comprising spring, Contact plate, limiting gasket, travel switch, described Contact plate has circular arc chamfering, described Contact plate and travel switch match, described Contact plate plane has through hole and lower through-hole, described spring housing is connected on pilot bar, described Contact plate is enclosed within pilot bar holddown spring by upper through hole, described Contact plate is enclosed within on steel rope and is fixed by lower through-hole.
Pilot bar described in the utility model is parallel with steel rope.
Pilot bar described in the utility model outer end is fixed with limiting gasket.
On steel rope described in the utility model, also cover has adjustment packing ring, and described adjustment packing ring and Contact plate are fixed.
The aperture of upper through hole described in the utility model and the diameter of pilot bar match, and the aperture of described lower through-hole and the diameter of steel rope match.
The utility model compared with prior art, has the following advantages and effect: 1, simple in structure, reasonable in design, easy for installation, detecting device is to install after steel rope installation is adjusted, and the installation of steel rope simultaneously regulates the reliability that can not affect detecting device; 2, dependable performance, the installation that does not affect steel rope regulates, high to the applicability of harsh environment, reliable in structure; 3, report to the police promptly and accurately, steel wire rope looseness or when fracture, Contact plate under the application force of spring with travel switch touching, signal and the action of regulation working arm thereby the control setup that makes to be connected with travel switch gives the alarm.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the structural representation of Contact plate.
In figure: travel switch 1, touch a little 11, Contact plate 2, upper through hole 21, lower through-hole 22, nut 3, bolt 4, limiting gasket 5, pilot bar 6, spring 7, adjust packing ring 8, steel rope 9, jam nut 10, working arm 12.
The specific embodiment
Below in conjunction with accompanying drawing and by embodiment, the utility model is described in further detail, and following examples are to explanation of the present utility model and the utility model is not limited to following examples.
Referring to Fig. 1 to Fig. 2, the testing device for wire ropes in the present embodiment comprises travel switch 1, Contact plate 2, nut 3, bolt 4, limiting gasket 5, pilot bar 6, spring 7, adjusts packing ring 8, steel rope 9, jam nut 10, working arm 12, thread end 13.
In the present embodiment, pilot bar 6 is welded on working arm 12, Contact plate 2 has circular arc chamfering, spring 7 is socketed on pilot bar 6, adjusting packing ring 8 is socketed on steel rope 9, pilot bar 6 is parallel with steel rope 8, parallel through hole 21 and the lower through-hole 22 of having of Contact plate 2, Contact plate 2 is enclosed within on pilot bar 6 by upper through hole 21, Contact plate 2 is enclosed within the thread end 13 of steel rope 9 by lower through-hole 22, the thread end 13 use jam nuts 10 of steel rope 9 are fixed on working arm 12 and get rid of tight, with nut 3 by Contact plate 2 with adjust packing ring 8 and be fixed on steel rope 9, and make to adjust packing ring 8 and be fixed with jam nut 10, Contact plate 2 holddown springs 7 simultaneously, pilot bar 6 outer ends are by the fixing limiting gasket 5 of bolt 4, prevent that Contact plate 2 from coming off from pilot bar 6.
On the present embodiment, the diameter of the aperture of through hole 21 and pilot bar 6 matches, and the diameter of the aperture of lower through-hole 22 and steel rope 9 matches.
Installation of the present utility model: adjust to after setting value in the predetermincd tension of steel rope 9, steel rope 9 use jam nuts 10 are got rid of and are fastened, again spring 7 is inserted in pilot bar 6, measure the installation site of travel switch 2, calculate the consumption of adjusting packing ring 8, and adjustment packing ring 8 is inserted in to steel rope 9, again Contact plate 2 is inserted in to pilot bar 6 and steel rope 9, by nut 3, Contact plate 2 is pressed to and is adjusted on packing ring 8 again, and Compress Spring 7, make spring 7 in compressive state, for prevent Contact plate 2 because of steel wire rope looseness or cut off time ejected pilot bar 6 by spring 7, need to be in the outer end of pilot bar hold-down bolt 4 and limiting gasket 5, finally travel switch 1 is installed on the working arm 12 at Contact plate 2 rears, and adjust travel switch 1 touch a little 11 and Contact plate 2 outer faces between spacing, to guarantee in the situation that steel rope 9 lost efficacy, can be reacted to timely and effectively on travel switch 1.
