Second through-hole 121 is located at the underface of the first through hole 111, so that the guardrail shaft 22 can be vertical
Ground is rotatably connected on the protective stent 1.
As shown in Figure 1 to Figure 3, tray carriage provided by the embodiment of the utility model, including vehicle frame 6 and above-mentioned protection knot
Structure, the protective stent 1 are fixedly connected on the vehicle frame 6.Specifically, the two sides of the vehicle frame 6 be respectively provided with one it is described anti-
Protection structure.
Wherein, the safeguard structure in left side, on the one hand, for being protected on the left of the tray carriage, on the other hand, can feel
Whether the left side for surveying the tray carriage collides, and signal is transferred to the controller of the tray carriage by inductive switch 4, by
Whether the controller of the tray carriage controls the tray carriage to dextrad racing, makes operator and vehicle region out of danger.
The safeguard structure on right side, on the one hand, for being protected on the right side of the tray carriage, on the other hand, institute can be sensed
Whether the right side for stating tray carriage collides, and signal is transferred to the controller of the tray carriage by inductive switch 4, by described
Whether the controller of tray carriage controls the tray carriage to left-hand racing, makes operator and vehicle region out of danger.
When the guardrail 21 of the safeguard structure is closed, vehicle attonity, it is necessary to the guardrail 21 be unfolded, support could be driven
Jiggering effectively prevent part operation person to drive tray carriage in the state of no guardrail 21.
In the driving process of tray carriage, under normal condition, the guardrail 21 is unfolded, and driver stands are described on pedal
Guardrail 21 can effectively offset outer throwing inertia when driver's turning.Meanwhile the inductive switch 4 can sense sensing element 3, control
Device processed obtains signal at this time, and tray carriage is working properly.When meeting burst turning collision accident, by reversely, can promptly make immediately
Far from accident point occurs for operator, guarantees driver safety to greatest extent.
As shown in Fig. 2, operate vehicle toward for right turn by driver, accident collision wall it is instantaneous, the induction is first
Part 3 is rotated with the guardrail 21, is detached from the induction range of the inductive switch 4, and feedback signal is transferred to by the inductive switch 4
The controller of the tray carriage, the controller of tray carriage enable security protection logic after obtaining signal, and tray carriage is without additional behaviour
In the case where work, moment becomes instruction of turning left from instruction of turning right originally, collides so that driver and vehicle are reversely detached from immediately
Region, after travelling a certain distance, tray carriage stops, and the warning lamp of tray carriage flashes.
The control logic of tray carriage provided by the embodiment of the utility model is as follows:
(1) under resting state, the guardrail 21 is closed, and 4 no signal of inductive switch, forward-reverse function is without sound at this time
It answers.If the guardrail 21 is unfolded at this time to reclose, since forward or backward signal, the response of tray carriage attonity is not detected.
(2) normally travel state, the guardrail 21 are unfolded, and the inductive switch 4 has a signal, tray carriage energy normally travel with
Operation.
(3) (forward or backward has signal, and the activation of guardrail collision prevention function is pre- Warm status) in driving process, work as side collision
When, the signal for the guardrail 21 that the inductive switch 4 senses disconnects, and tray carriage executes inverted running instruction, after instruction, support
Jiggering restores to resting state, and guardrail 21 need to be unfolded again without response, could restore normally travel state by driving functions.
This mechanism can effectively ensure that the safety of driver in extreme cases, damage is preferably minimized, protection staff is exempted from
It is hurt.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
