Abstract
The utility model relates to an automatic meso-position locking device for a truck mounted crane. The automatic meso-position locking device for the truck mounted crane comprises a rack, a rotary table locking lug, a rack locking base and an electric control system, wherein the rack locking base is arranged on the rack, a cylinder is fixedly arranged on the rack locking base by virtue of bolts, and the rack locking base is internally provided with a locking pin; the rotary table locking lug is also provided with a photoelectric switch; the electric control system comprises a chassis gas tank, an electromagnetic valve and a delay controller, wherein the chassis gas tank is connected with a port R of the electromagnetic valve, and the port A of the electromagnetic valve is connected with the cylinder; and the electromagnetic valve is also connected with the delay controller, and the delay controller is connected with a hand switch, a photoelectric switch, a power takeoff electromagnetic valve, a power takeoff switch and a chassis power supply. The automatic meso-position locking device for the truck mounted crane has the beneficial effects of having a function of automatically returning to a meso position and locking, not needing fussy manual operation, and effectively eliminating a potential safety hazard.
Description
[technical field] the utility model relates to the mechanical equipment parts, specifically a kind of truck-mounted crane meta automatic locking apparatus.
[background technology] is present, and the truck-mounted crane on the market need manually to insert stop pin in the process of moving, and need climb up vehicle frame and operate, and are not only loaded down with trivial details, and therefore operating personal exists bigger potential safety hazard in case carelessness promptly can cause great safety misadventure.
[summary of the invention] the utility model provides a kind of truck-mounted crane meta automatic locking apparatus at the problems referred to above.
This truck-mounted crane meta automatic locking apparatus, comprise frame, turntable latch ear, frame locking seat and electric control system, it is characterized in that, frame locking seat is installed on the frame, frame locking seat is gone up and by bolt cylinder is installed, and is provided with stop pin in the frame locking seat; Photoelectric switch also is installed on the turntable latch ear; Described electric control system comprises chassis gas tank, electromagnetic valve and delay controller, and the chassis gas tank is connected with the R mouth of electromagnetic valve, and the A mouth of electromagnetic valve is connected with cylinder; Also be connected with delay controller on the electromagnetic valve, be connected with hand switch, photoelectric switch, power takeoff electromagnetic valve, power take-off valve and chassis power supply on the delay controller.
The beneficial effects of the utility model are: this device has gets back to the function that meta locks automatically, does not need artificial troublesome operation, has eliminated potential safety hazard effectively.
[description of drawings]
Fig. 1 is a structural representation of the present utility model
Fig. 2 is an electrical schematic diagram of the present utility model
Among the figure: 1, turntable latch ear, 2, photoelectric switch, 3, stop pin, 4, frame locking seat, 5, cylinder, 6, chassis gas tank, 7, electromagnetic valve, 8, delay controller, 9, the power takeoff electromagnetic valve, 10, power take-off valve, 11, hand switch, 12, the chassis power supply, 13, frame.
[specific embodiment] is described below enforcement of the present utility model below in conjunction with accompanying drawing:
With reference to Fig. 1, frame locking seat 4 is installed on the frame 13, by bolt cylinder 5 is installed on the frame locking seat 4, be provided with stop pin 3 in the frame locking seat 4; Photoelectric switch 2 also is installed on the turntable latch ear 1.
With reference to Fig. 2, electric control system comprises chassis gas tank 6, electromagnetic valve 7 and delay controller 8, and chassis gas tank 6 is connected with the R mouth of electromagnetic valve 7, and the A mouth of electromagnetic valve 7 is connected with cylinder 5; Also be connected with delay controller 8 on the electromagnetic valve 7, be connected with hand switch 11, photoelectric switch 2, power takeoff electromagnetic valve 9, power take-off valve 10 and chassis power supply 12 on the delay controller 8.
After power take-off valve 10 was closed, delay controller 8 continued to give the power takeoff electromagnetic valve 9 power supplies, when turntable is turned back to latched position, and photoelectric switch 2 work, electromagnetic valve 7 gets electric, and cylinder 5 ejects stop pin 3 and finishes lock function.At this moment, delay controller 8 cuts off the power supply of power takeoff electromagnetic valve 9, and whole locking work is finished.Press power take-off valve 10, delay controller 8 cuts off the power supply of electromagnetic valve 7, stop pin 3 withdrawals, loop wheel machine normal operation.
