Description
Technical field
The utility model relates to a kind of towing machine, particularly a kind of towing machine fender guard.
Background technology
Along with the develop rapidly of elevator industry, use the place of staircase increasing, the safety problem of staircase has also more and more received social concern.With regard to arm rest lift traction machine, in order to obtain better performance, and increased inertia wheel, inertia wheel is installed in the axial end of towing machine, and inertia wheel and towing machine rotate synchronously.Generally adopt the mode that adds protective cover at present, isolate inertia wheel to reach the effect of protection.But when towing machine is safeguarded, open protective case after, towing machine is still in running, at this moment, inertia wheel is also rotating, thereby makes service personnel when towing machine is keeped in repair, bring potential safety hazard, can not ensure maintainer's safe operation.
The utility model content
The utility model technical matters to be solved is, overcomes above deficiency, and a kind of towing machine fender guard is provided, and with when towing machine is safeguarded, ensures the safe operation of service personnel.
In order to solve the problems of the technologies described above; The technical scheme of the utility model is: a kind of towing machine fender guard; Comprise the protective case that covers the inertia wheel top; And limit switch outer circumference surface, that be used to control the towing machine operation or stop that is arranged on towing machine, the switch lever of said limit switch is crimped on the below of protective case.
Further; Said protective case comprises over cap, is hinged with at least one the first adapter plates on the edge of said over cap; Said first adapter plate is provided with at least one first through hole; Also be fixedly connected with at least one the second adapter plates on the edge of said over cap, said second adapter plate is provided with at least one second through hole, and said first adapter plate and second adapter plate are distributed in the both sides of the vertical or horizontal center line of said over cap.
Further, the surface configuration of said over cap is a rectangle.
Further, the surface configuration of said over cap is circular.
Compared with prior art, the utility model is provided with limit switch at the outer circumference surface of towing machine, and the switch lever of limit switch is crimped on the below of protective case, and limit switch is used to control the towing machine operation or stops.After closing protective case, because the switch lever of limit switch is crimped on the protective case, limit switch is in closure state; Connect towing machine; Make the towing machine normal operation, then inertia wheel is also rotating, because protective case covers the top of inertia wheel; Therefore, protective case has played the effect of insulation blocking to inertia wheel.After opening protective case, the switch lever of limit switch resets, and limit switch is in open-circuit condition; Then towing machine shuts down, because towing machine and inertia wheel rotate synchronously, so inertia wheel has also stopped rotation; This moment is when safeguarding staircase, owing to after opening protective case, eliminated the potential safety hazard that the rotation of inertia wheel brings; Therefore, can ensure the safe operation of service personnel.

Shown in the figure: 100, protective case, 110, protection end, 120, first adapter plate, 121, first through hole, 130, second adapter plate, 131, second through hole, 200, inertia wheel, 300, limit switch, 301, switch lever, 400, towing machine.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail:
Please refer to Fig. 1; The utility model towing machine fender guard; Comprise the protective case 100 that covers inertia wheel 200 tops; And the limit switch 300 outer circumference surface, that be used to control towing machine 400 operations or stop that is arranged on towing machine 400, the switch lever 301 of said limit switch 300 is crimped on the below of protective case 100.
Please refer to Fig. 1-3, said protective case 100 comprises over cap 110; The surface configuration of over cap 110 can be a rectangle; Also can be circular, also possibly be polygon, as long as can cover the inertia wheel 200 of the axial end of towing machine 400; Wherein, the surface configuration of the over cap 110 of Fig. 3 is the rectangle that has lead angle; Be hinged with at least one the first adapter plates 120 on the edge of said over cap 110; Said first adapter plate 120 is provided with at least one first through hole 121; Go back at least one of captive joint on the edge of said over cap 110 second adapter plate 130 is arranged; Said second adapter plate 130 is provided with one second through hole 131 at least, and said first adapter plate 120 is distributed in the said over cap 110 vertical perhaps both sides of horizontal center line with second adapter plate 130.
Please refer to Fig. 1, Fig. 2, first adapter plate 120 is an articulated form with the connection mode of over cap 110, and the connection mode of second adapter plate 130 and over cap 110 its objective is the opening and closing that make things convenient for protective case 100 for captiveing joint.Use bolt protective case 100 to be fixed on first adapter plate 120 and second adapter plate 130 on the housing of towing machine 400 through first through hole 121 and second through hole 131 respectively; Preferably; The bolt of second adapter plate 130 adopts fly-headed bolt, so that fast speed dismounting and assembling.When needs are safeguarded towing machine 400; After disassembling the fly-headed bolt of second adapter plate 130, over cap 110 is upwards lifted, again because the over cap 110 and first adapter plate 120 are hinged; Then over cap 110 will be to the direction upset of first adapter plate 120, and then protective case 100 is opened; During assembling, over cap 110 is turned to second adapter plate, 130 directions from first adapter plate, 120 directions again after, through fly-headed bolt second adapter plate 130 is fixed on the housing of towing machine 400, then protective case 100 is closed.Therefore, the protective case 100 of the utility model is when safeguarding, the operation of opening and closing is more convenient.
The utility model is provided with limit switch 300 at the outer circumference surface of towing machine 400, and the switch lever 301 of limit switch 300 is crimped on the below of protective case 100, and limit switch 300 is used to control the towing machine operation or stops.After closing protective case 100, because the switch lever 301 of limit switch 300 is crimped on the protective case 100, limit switch 300 is in closure state; Connect towing machine 400; Make towing machine 400 normal operations, then inertia wheel 200 is also rotating, because protective case 100 covers the top of inertia wheel 200; Therefore, 100 pairs of inertia wheels 200 of protective case have played the effect of insulation blocking.After opening protective case 100, the switch lever 301 of limit switch 300 resets, and limit switch 300 is in open-circuit condition; Then towing machine 400 stops operating, and owing to towing machine 400 and inertia wheel 200 rotate synchronously, so inertia wheel 200 has also stopped; This moment is when safeguarding staircase, owing to after opening protective case 100, eliminated the potential safety hazard that the rotation of inertia wheel 200 brings; Therefore, can ensure the safe operation of service personnel.
