Abstract
The invention provides a inhibiting device lift buggy in the vacuum furnace, including furnace body, lift car, nuts drived by tears drived by lift motor on the high, medium, low position three control screw rod. The buggy position is determined by the nut docked position and a braking device is set at the front of the lift motor for control the nuts on the screw rod to open the braking switch when touching the inductive switch so as to scram without inertial phenomenon. The invention can correctly position the buggy in the furnace outside the furnace.
Description
Technical field
The present invention relates to a kind of vacuum oven equipment, especially the lifting truck stop means in the vacuum oven equipment.
Background technology
The lifting of present homemade truck is spacing to be to connect inner truck pull bar and localized by eccentric wheel, and the drive eccentric wheel that moves up and down of truck, eccentric wheel are equipped with high, medium and low three limit switches, thereby reaches the high, medium and low purpose of control.Because eccentric wheel must be in the outside of vacuum oven, so this structure must perforate on body of heater, increased the probability of gas leakage, add because the motional inertia of truck and shove charge weight inconsistent, often causing travel switch to cut off the back causes owing to inertia is not of uniform size, the position that truck stopped is also accurate inadequately, is easy to break down when level run, and might clashes into siege and damage equipment and workpiece.
Summary of the invention
Task of the present invention provides a kind of spacing performance vacuum hardening boiler accurately.
For achieving the above object, the scheme that is adopted is:
Lifting truck stop means in a kind of vacuum oven equipment, comprise body of heater, lift car, it is characterized in that relying on the nut on the three control screw mandrels in the high, medium and low position of lifting motor driven gear transmission, put to determine the position of truck by nut institute off-position, and the front end at the car lifting motor is equipped with the brake emergency stop device, the nut of control on the screw mandrel touches inductive switch and opens and suddenly stop coil switch, scram, and can not produce the phenomenon of inertia.
The truck that can carry out carrying out in the stove outside stove is accurately located like this.

Embodiment
The present invention will be further described below in conjunction with accompanying drawing: truck (10) position can be transferred to master gear (8) or connected gear (7) is controlled by reducing motor (9), and its accurate position is controlled by limit switch (2).
Vacuum lifting truck stop means is made up of truck elevating screw, reducing motor, braking devices, transmitting gear and the three control screw mandrels in high, medium and low position and nut.One of master gear is installed before lifting motor is driven three gears on the control screw mandrel, nut on the screw mandrel is along with the rotation of lifting motor moves forward and backward, when truck arrives the position that needs, nut institute off-position is put by limit switch and is controlled, the limit switch transmission signal is given PLC, the scram when control puts in place.High, medium and low bit position adjustment is decided by the position of three rhizoid bar upper nuts successively.
Claims (2)
1. the lifting truck stop means in the vacuum oven equipment, comprise body of heater, lift car, it is characterized in that relying on the nut on the three control screw mandrels in the high, medium and low position of lifting motor driven gear transmission, put to determine the position of truck by nut institute off-position, and the front end at the car lifting motor is equipped with the brake emergency stop device, the nut of control on the screw mandrel touches inductive switch and opens and suddenly stop coil switch, scram, and can not produce the phenomenon of inertia.
2. according to claim 1, it is characterized in that vacuum lifting truck stop means is made up of truck elevating screw, reducing motor, braking devices, transmitting gear and the three control screw mandrels in high, medium and low position and nut.
