Supporting leg contracting state detecting method and device for special vehicle

Abstract

The invention discloses a supporting leg contracting state detecting method and device for a special vehicle. The method includes the steps of firstly, installing the detecting device; secondly, pushing a detecting rod to slide upwards through a collision block when a perpendicular movement leg contracts; thirdly, driving the detecting rod to move leftwards when a horizontal movement leg contracts; fourthly, triggering a detecting switch to send out a contracting state signal through the detecting rod when the perpendicular movement leg and the horizontal movement leg both reach the contracting positions; fifthly, sending out a disengagement signal through the detecting switch when any one supporting leg leaves the contracting position; sixthly, obtaining a vehicle driving state signal through a controller by means of a parking brake and a gear position, and starting an alarm device to give an alarm when the controller receives a supporting leg disengagement contracting state signal. By means of the detecting device, the contracting states of the perpendicular movement leg and the horizontal movement leg can be detected at the same time, the detecting and control principle is simple, no large electrical system or complicated electrical layout is needed, and cost and damage risk are reduced.

Description

technical field [0001] The invention relates to a detection method and equipment, in particular to a detection method and a detection device for the retracted state of the outriggers of a special-purpose vehicle with horizontal outriggers and / or vertical outriggers. Background technique [0002] A special-purpose vehicle is a car that has special functions and is engaged in special transportation tasks or special operations. In order to ensure the operation stability of special equipment and the safety of special operations, special vehicles are often equipped with outrigger devices. The outrigger device can be extended horizontally to both sides of the vehicle, and can also be extended vertically to the ground. After the outriggers are extended, the operation stability of the special vehicle can be increased. When the special vehicle is in the driving state, the outrigger device must be in the retracted state, otherwise the outrigger will affect the passability of the vehi...

AI Technical Summary

Problems solved by technology

In fact, after long-term use of hydraulic oil, impurities in it such as iron filings, excessive internal leakage of hydraulic locks or balance valves after long-term use, etc., will reduce the performance of hydraulic locks or balance valves, and there is no lock Hidden dangers of living on outriggers

The mechanical locking mechanism may not be able to lock the outrigger under long-term use and harsh conditions, such as excessive bumps, excessive vehicle turning speed, corrosion of the locking mechanism, failure, etc.

During the driving process of the vehicle, it can be roughly confirmed by visual inspection whether the horizontal outriggers are protruding, but it is impossible to confirm whether the vertical outriggers are protruding. Moreover, special-purpose vehicles are often large in size, and the driver has a large visual blind spot, which increases the the difficulty of judging

Moreover, this method cannot accurately confirm the state of the outriggers, and will distract the driver's attention, posing a safety hazard

[0003] The movable legs include horizontal movable legs and vertical movable legs, so according to the traditional position detection method, position sensors or trigger sensors need to be set respectively for the horizontal movable legs and vertical movable legs, which increases the complexity of the equipment and not only increases the cost, and increases the chance of failure

Since there is not only a space distance between the horizontal movable leg and the vertical movable leg in the installation position, but also the movement directions of the two are inconsistent (generally perpendicular to each other, but there may also be an angle), so according to the existing technology, it is impossible to use a set of detection equipment to simultaneously Detect the retracted state of the horizontally movable leg and the vertically movable leg
