Abstract
The utility model relates to a landing leg checkout gear of a special purpose vehicle, and a proximity switch is arranged under a fixed landing leg of the special purpose vehicle. The landing leg checkout gear is characterized in that a mounting deck is fixed under the landing leg; the mounting deck is composed of a horizontal long plate and a fixed vertical short plate; the proximity switch is arranged on the vertical short plate of the mounting deck; a detecting lever is arranged at the distal end of the horizontal long edge of the mounting deck through a pin roll; a spring is arranged on the detecting lever; the spring leads the lever to have the normal position that the end of the lever acting with the proximity switch is lower than the proximity switch; an idler wheel is arranged on the other end of the lever; the located position of the idler wheel is higher than the lower surface of a horizontal landing leg when the lever is in the normal position. The landing leg checkout gear has the optimized scheme that an amplifier encloser is arranged, and all the parts of the proximity switch and the detecting lever adjacent to the proximity switch are arranged inside the amplifier encloser. Based on the existing checkout gear, lever action is added in the landing leg checkout gear, so that the original tiny detection distance is amplified manifold, and the adjustable distance of the proximity switch is also increased manifold, so as to lead the obtained signal to be more reliable and stable.
Description
Technical field
The utility model relates to a kind of detecting device, is specifically related to a kind of special-use vehicle supporting leg detecting device.
Background technology
Some are applied to the special-use vehicle of special occasions, will come support chassis and working part by supporting leg when work.Being used for one of mode that whether the detection of vertical supporting leg land is exactly to install one at fixed supporting leg collar extension place near switch, and its structure as shown in Figure 1.
Fig. 1 is a special-purpose vehicle leg structure scheme drawing in the prior art: 1 for horizontal support legs, and 2 be vertical leg, 3 be used for whether the detection of vertical supporting leg land near switch, 4 is fixed supporting leg.No matter whether horizontal support legs 1 stretches out, and is in operating state all the time near switch 3; But after vertical supporting leg 2 stretches out, because horizontal support legs 1 raises, exceed the detection distance with distance near switch 3, stop action near switch 3, state changes, and stretches out thereby detect supporting leg.
But this detection mode is because when vertical leg was stretched out, the value that horizontal support legs raises was very little, and for limited near switch active distance adjustable space, causes signal source unreliable.The phenomenon of performance is, there is mistake in signal, and the buzzer phone that is used to warn is usually reported to the police without reason, causes a lot of troubles and confusion.
Summary of the invention
The purpose of this utility model is exactly in order to overcome the defective of above-mentioned prior art, provide a kind of can reliable Detection vertical leg mode of operation, and the detecting device that detected state is accurately reflected.
The technical solution of the utility model is, a kind of special-use vehicle supporting leg detecting device, below the special-use vehicle fixed supporting leg, be provided with near switch, it is characterized in that, the supporting leg below is fixed with an erecting frame, this erecting frame is made of with fixing vertical short slab horizontal long slab, on the described vertical short slab that is installed in this erecting frame near switch; The far-end on the long limit of this erecting frame level is equipped with one by bearing pin and detects lever; This detection lever is provided with spring, and this spring makes the normality position of lever be: be lower than near switch with the end near on-off action; The other end at lever is provided with roller, when lever is in the normal state the position, this roller the lower surface that the position is higher than horizontal support legs is set.
When supporting leg did not stretch out, this detecting device was not worked by (lever be in the normal state position), lever with near an end of on-off action owing to be lower than EFFECTIVE RANGE, so near not action of switch near switch; Compressing roller after horizontal support legs stretches out, lever is by the effect of bearing pin and spring, other end perk, it highly is higher than the useful effect zone near switch, also not action; After vertical leg was stretched out, horizontal support legs raise, and its top contacts with the fixed supporting leg top, distance between roller and the horizontal support legs increases, and lever is owing to the effect of spring and bearing pin, and the other end is done return motion, just in time enter near in the on-off action scope near the switch action message, signal upset.
Above scheme optimization design has:
1, also be provided with the amplifier case, this amplifier case is fixed on the erecting frame, and is described near switch and detect lever and be installed in this amplifier case near the part near switch.
2, the lateral plan of described erecting frame adopts horizontal L type (or be called " falling " L type, promptly " L " clockwise rotates 90 degree).
The utility model has increased leverage on existing detecting device basis, make original very little detection distance amplify at double, also increases exponentially near the adjustable distance of switch, thereby makes the signal of obtaining reliable more and stable.
Description of drawings
Fig. 1 is the utility model background technology structural representation;
Fig. 2 is the utility model structural representation;
Fig. 3 is that horizontal support legs stretches out, view of the present utility model when vertical leg is not stretched out;
View when Fig. 4 is the utility model work.
The specific embodiment
Embodiment 1, is applied to special-use vehicle supporting leg detecting device, and as shown in Figure 2, whole device is installed on the below of fixed supporting leg 4 by erecting frame 10.Detect lever 8 and be fixed on the erecting frame 10 by bearing pin 6, lever 8 is provided with spring 7, and this spring 7 makes lever 8 when normality, is lower than near switch 3 with an end that acts near switch 3; The other end at lever 8 is provided with roller 5, lever 8 when normality, this roller 5 the lower surface that the position is higher than horizontal support legs 4 is set.Amplifier case 9 is fixed on the erecting frame 10, is installed in this amplifier case 9 near switch 3 and the part near near switch 3 that detects lever 8.
When level and vertical leg all are failure to actuate, lever 8 with near an end of switch 3 effects owing to be lower than useful effect zone (as shown in Figure 2), so near not action of switch 3 near switch 3; Compressing roller 5 after horizontal support legs 1 stretches out, lever 8 be by the effect of bearing pin 6 and spring 7, make other end perk its highly be higher than useful effect zone (as shown in Figure 3) near switch 3, also not action; After vertical leg 2 is stretched out, horizontal support legs 1 raises, its top contacts with fixed supporting leg 4 tops, distance between roller 5 and the horizontal support legs 2 increases, lever 8 is because the effect of spring 7 and bearing pin 6, the other end is done return motion, just in time enter near (as shown in Figure 4) in switch 3 sphere of action near switch 3 action messages, signal upset.
