Abstract
The utility model discloses an anti-strip device of a tamping head of a middle tamping wagon. A locking pin proximity switch is arranged on the edge of the pin shaft of a hinge seat of a roof side beam of a main frame, a highest point detecting proximity switch is arranged on the side face, below the locking pin proximity switch, of the main frame, the lower end of the highest point detecting proximity switch is close to the top face of an upper beam of a tamping device, and the two proximity switches are connected on a driving motor circuit of the tamping wagon in series. The anti-strip device of the tamping head of the middle tamping wagon is simple in structure, when the highest point detecting proximity switch of the tamping device meets an action condition, a locking pin can be guaranteed to be inserted into the pin hole of the tamping device, the tamping device is locked reliably, and safe operation of the tamping wagon is guaranteed.
Description
Technical field
The utility model relates in a kind of smashes car tamping head anti-drop device.
Background technology
Tamping car is rail track in ew line construction, maintenance activity, to track carry out that automatic leveling rises, track lining, ballast aggregate tamping operation, make track circuit reach the large-scale maintenance machinery equipment of the requirement of line design standard and line rule.Tamping car enters closed interval under running status, and arriving after operating location tamping car is to start working after job state by running state conversion.After end-of-job, the operation of should being returned the vehicle to the garage and knock off packs up each equipment lock, and now the tamping unit of tamping car should be thus lifted to highest order, and pulls jettron and make stop pin insert in the tamping head pin-and-hole, the locking tamping unit.Trigger the stop pin approach switch simultaneously and send locking signal to the gearbox control module, tamping car enters running status.In actual motion, due to operating personnel's maloperation, tamping unit is not promoted to highest order, and the locking jettron is just pulled.Now stop pin does not insert in the tamping head pin-and-hole, and tamping unit is not fixed.But the stop pin approach switch is triggered, the gearbox control module obtains locking signal, and tamping car enters running status.Tamping car is in high-speed cruising, because tamping unit hydraulic control system power supply is closed.Tamping unit falls under Action of Gravity Field, and tamping pickaxe inserts railway roadbed, causes a serious accident.
Summary of the invention
The purpose of this utility model is to provide in a kind of smashes car tamping head anti-drop device, and this measure can effectively prevent that tamping unit from entering running status in unblocked situation.Guaranteed the safe operation of tamping car.
The purpose of this utility model is to realize like this, smash car tamping head anti-drop device in a kind of, on the hinged seat bearing pin limit of main car frame roof side rail, a stop pin approach switch is being set, on the main car frame of this side, stop pin approach switch below, a peak is being set and is detecting approach switch, peak detects the approach switch lower end near tamping unit top rail end face, and two approach switchs are connected on tamping car drive motors circuit.
When the utility model is used, only have two approach switchs all to move, tamping car just can travel.When tamping unit highest order approach switch meets operation condition, can guarantee that stop pin inserts in the tamping unit pin-and-hole.Tamping unit is by positive lock.Prevent that tamping unit from entering running status in unblocked situation, guaranteed the safe operation of tamping car.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is main TV structure schematic diagram of the present utility model.
The specific embodiment
Smash car tamping head anti-drop device in a kind of, as shown in Figure 1, on the hinged seat bearing pin limit of main car frame roof side rail 1, a stop pin approach switch 2 is being set, a peak is being set on the main car frame of these stop pin approach switch 2 sides, below and is detecting approach switch 3, peak detects approach switch 3 lower ends near tamping unit top rail 4 end faces, and two approach switchs 2,3 are connected on tamping car drive motors circuit.
Claims (1)
1. smash car tamping head anti-drop device in one kind, it is characterized in that: on the hinged seat bearing pin limit of main car frame roof side rail, a stop pin approach switch is being set, on the main car frame of this side, stop pin approach switch below, a peak is being set and is detecting approach switch, peak detects the approach switch lower end near tamping unit top rail end face, and two approach switchs are connected on tamping car drive motors circuit.
