Abstract
The utility model relates to a lifted driving safety control device for self-dumping trucks, and belongs to a time delay control device for lifted driving of self-dumping trucks. The device comprises a carriage lifting hydraulic device and a pneumatic truck stopping braking device, and is characterized in a pressure switch is provided in the pipeline of the carriage lifting hydraulic device, and an electromagnetic valve is provided in the pipeline of the pneumatic truck stopping braking device; the pressure switch is connected to the circuit of the electromagnetic valve, and connected to the vehicular electric power through a forced driving button; the time relay coil and the permanent open contact thereof are connected to the other end of the pressure switch and the electromagnetic valve through conductive wires. When the moving truck needs to be lifted, the forced driving button is pressed, the time relay is electrified, and the carriage is lifted by the determined safe distance within the time delay. After the time delay is completed, the time relay is activated, the electromagnetic valve is electrified, and the truck is in the braking state again. The device is simple in structure, low in cost, easy for installation, convenient for operation, with improved efficiency; and has reliable performance, can prevent occurrence of accidents due to the long lifting distance of the carriage of the self-dumping truck.
Description
Technical field
The utility model belongs to controlling device for vehicle running, relates in particular to the compartment lifting of dumping car and the safety and interlock device of Parking.
Background technology
Dumping car is in operation process, and normal because lifting follow-up continuing in compartment appears in machinery and artificial origin sails, bump is located at the pipe network and the Architectural Equipment in the road sky, causes casualties and property damage, therefore causes people's attention.China's utility model patent disclosed " dumping car compression air brake lifting electric interlocking installation " (ZL99228333.7).This device is made up of pneumatic electric switch, manual electrical switch, T-pipe joint, electromagnetic valve, manual power switch, electromagnetic valve are connected with pneumatic electric switch circuit respectively, pneumatic electric switch is connected with T-pipe joint, and electromagnetic valve also is communicated with Parking operating valve, Parking relay valve gas circuit respectively.After the compartment lifting, pneumatic electric switch pressurized, vehicle is in the braking during standstill state; After the compartment fell, pneumatic electric switch unclamped, and braking during standstill is removed, and vehicle can be exercised.Defective is to be under the lifting state when dumping car, and vehicle moves fully and controlled by operating personal, influences operating rate, if miles of relative movement prolonged after operation field required the compartment lifting, has accident potential.
Summary of the invention
In order to overcome the defective that prior art exists, the purpose of this utility model provides a kind of dumping car lifting driving safety control setup, and time delay device is set, make dumping car compression air brake trunk certain safety distance that can lifting travels, strengthen safety, improve operating rate, avoid accident to take place.
Dumping car lifting driving safety control setup, comprise compartment lifting hydraulic efficiency gear and pneumatic holding brake device, characteristics are to establish pressure switch in the hydraulic tubing of compartment lifting hydraulic efficiency gear, establish electromagnetic valve in the pneumatic line of pneumatic holding brake device, pressure switch is connected with electromagnetic valve circuit, by forcing the walking button to be connected on the vehicle power; Time relay coil and open contact thereof are connected the other end of pressure switch, electromagnetic valve respectively by lead.During the compartment lifting, 2/2-way is often opened in the closed gas circuit of pressure switch, closed electromagnetic valve, and vehicle is in braking mode; When needing the lifting compartment to move, press and force to travel button, the time relay energising, in delay time, the safety distance of setting is moved in the compartment lifting, after time-delay finishes, the time relay closing of contact, the electromagnetic valve energising, vehicle is in braking mode again.Behind the compartment return, travel again in vehicle side.
Compared with prior art, advantage is: this apparatus structure is simple, and cost is low; Install easily, easy to operate, safety distance is adjustable, improves operating rate; Dependable performance prevents that effectively body of tipper carriage lifting operating range is long, avoids train operation accident to take place.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is a dumping car lifting driving safety control setup electrical schematic diagram.
The specific embodiment
As seen from Figure 1, this device connects into lifting hydraulic efficiency gear (not marking among the figure) by the road by hydraulic reservoir, lifting oil pump, check valve, elevating ram, limit valve, form pneumatic holding brake device (not marking among the figure) by the road by air receiver, hand brake valve, electromagnetic valve, succeeding pump, brake cylinder, establish pressure switch YL in the compartment lifting hydraulic efficiency gear pipeline, establish electromagnetic valve DF in the pneumatic holding brake device pipeline; Electromagnetic valve DF adopts the 2/2-way electromagnetic valve; Pressure switch YL end is connected with electromagnetic valve DF, and the other end and contact 1 direct connection of forcing driving button K are connected with the contact 2 of the button K that walks through the open contact YS1 of time relay YS and pressure; The coil of time relay YS is connected with electromagnetic valve DF with the contact 2 of forcing walking button K respectively; Electromagnetic valve DF is connected with vehicle power E.During the compartment lifting, pressure switch YL closure, electromagnetic valve DF closes, and vehicle is in braking mode; When lifting is moved, press and force walking button K, the safety distance of setting is moved in compartment lifting in setting delay time; After time relay YS time-delay finished, vehicle was in braking mode again automatically.Behind the compartment return, vehicle can cruising.
Claims (2)
1. dumping car lifting driving safety control setup, comprise compartment lifting hydraulic efficiency gear and pneumatic holding brake device, it is characterized in that establishing pressure switch (YL) in the hydraulic tubing of compartment lifting hydraulic efficiency gear, the pneumatic line of pneumatic holding brake device is established electromagnetic switch (DF); Pressure switch (YL) is connected with electromagnetic valve (DF) circuit, by forcing walking button (K) to be connected on the vehicle power (E); Time relay (YS) coil and open contact (YS1) thereof are connected the other end of pressure switch (YL), electromagnetic valve (DF) respectively by lead.
