Abstract
The utility model relates to a protecting device for non-neutral-position starting of a loading machine. The protecting device comprises an inductor, an inducting plate, a flexible shaft fixing frame, a speed changing flexible shaft and a flexible shaft fixing frame extending-out end. The flexible shaft fixing frame is fixed with the flexible shaft fixing frame extending-out end, one end of the speed changing flexible shaft is perpendicularly connected with the flexible shaft fixing frame extending-out end through a groove of the flexible shaft fixing frame extending-out end, and the other end of the speed changing flexible shaft is perpendicularly connected with the inducting plate through a hole at the port of the inducting plate. The inductor is perpendicularly connected with the flexible shaft fixing frame extending-out end through a hole at the port of the flexible shaft fixing frame extending-out end to adjust the distance between the inductor and the plane where the induction plate is located to be within an effective induction distance. The induction plate and the flexible shaft fixing frame extending-out end are both in L shapes. The protecting device for the non-neutral-position starting of the loading machine has the advantages of avoiding accidents caused by the fact that the loading machine is started under the non-neutral-position condition and being simple, easy to operate, safe and reliable.
Description
Technical field
The utility model relates to the non-neutral gear of a kind of loader and starts protective gear, is used to prevent that loader from starting under the situation of non-neutral gear, belongs to the loader technical field.
Background technique
At present; When loader is started; The loader gear does not start complete machine at neutral position situation appears through regular meeting; This situation is abnormally dangerous, opens the throttle if the manipulator does not recognize gear stages or takes other unreasonable operation, might surrounding or personnel be damaged; Loader starts under non-neutral gear situation in addition, and motor and bivariant system system are had damage, and frequent non-neutral gear starts and can shorten its working life; Though some has the neutral protective function, adopt the flexible axle switch, the mechanical detection neutral gear position is installed complicacy, and poor reliability is damaged easily and was lost efficacy, and is unfavorable for guaranteeing that long-term safety starts.
Summary of the invention
The purpose of the utility model provides the non-neutral gear of a kind of loader and starts protective gear, and purpose is to prevent that loader from starting under the situation of non-neutral gear, thereby causes accident.
In order to achieve the above object; The technological scheme of the utility model provides the non-neutral gear of a kind of loader and starts protective gear; Form by inductor, sensing plate, flexible axle fixing frame, speed change flexible axle and flexible axle fixing frame external part; Flexible axle fixing frame and flexible axle fixing frame external part are fixed, and an end of speed change flexible axle is through the groove and vertical connection of flexible axle fixing frame external part of flexible axle fixing frame external part, and the other end of speed change flexible axle is connected with sensing plate is vertical through the hole of sensing plate port; Inductor is through the hole and vertical connection of flexible axle fixing frame external part of flexible axle fixing frame external part port; Regulate in distance to the actual induction distance on plane, itself and sensing plate place, realize the non-contact detection neutral gear position, can work reliably and with long-term.
Sensing plate is L shaped.
Flexible axle fixing frame external part is L shaped.
This device judges through the break-make of normal open switch whether gearbox is in neutral position.If the non-neutral gear of gearbox does not then have signal to send, complete machine starts circuit and is in off state, can not start; Have only gearbox when neutral position, induced signal just can send, and this signal advances to start circuit through the conversion serial connection, makes the startup circuit unobstructed, and complete machine can start.
The utility model has the advantages that: prevent that loader from starting under the situation of non-neutral gear, thereby cause accident, device is simple, and operation is safe and reliable easily.
Description of drawings
Fig. 1 is the structural representation that the non-neutral gear of a kind of loader starts protective gear.
Fig. 2 is the circuti diagram that the non-neutral gear of a kind of loader starts protective gear.
Embodiment
Specify the utility model below in conjunction with embodiment.
Embodiment
As shown in Figure 1; The non-neutral gear of a kind of loader starts protective gear; Form by inductor 1, sensing plate 2, flexible axle fixing frame 3, speed change flexible axle 4 and flexible axle fixing frame external part 5; Flexible axle fixing frame 3 is fixing with flexible axle fixing frame external part 5, and an end of speed change flexible axle 4 is through the groove and 5 vertical connections of flexible axle fixing frame external part of flexible axle fixing frame external part 5, and the other end of speed change flexible axle 4 is through the hole and 2 vertical connections of sensing plate of sensing plate 2 ports; Inductor 1 is through the hole and 5 vertical connections of flexible axle fixing frame external part of flexible axle fixing frame external part 5 ports, distance to the actual induction of regulating itself and plane, sensing plate 2 place apart from.The external part of sensing plate 2 and flexible axle fixing frame 3 is all L shaped.
As shown in Figure 1, current location is the neutral position of gearbox control valve, when being in this position; Sensing plate pulls through the speed change flexible axle and arrives the proper top of inductor face, and is as shown in Figure 2, makes inductor receive signal; The inductor of receiving behind the signal becomes closed state by opening; The inductor closed circuit starts circuit through relay control, makes that to start in the circuit 4 and No. 82 lines unobstructed, and complete machine can start.
