Abstract
The invention is a buried electric vehicle erector, including a bearing frame, a sleeve supporting lift tube and fixed on the bottom baseboard of the bearing frame, and gear box and reducer, and the lift mechanism includes screw, lift tube, rotary tube and oil tube, coaxially covered together from inside to outside, the lift tube is supported on the bearing nut screwed on the rotary screw rod, under the bearing nut is a safety nut screwed on the screw rod and loosely cooperating with the lift tube through key. When it does not work, the lift tube withdraws in the base plate, and the whole erector can be buried underground or under the basic surface. When used, by gear transfer, the reducer drives the rotary tube and the screw rod connected with the rotary tube to rotate, here, the lift tube rises and falls along the guide block. When the bearing nut are worn and shaved, the screw rod directly applies force on the safety nut, at this moment, the safety nut breaks away from the key so as to cause the idling of both the safety nut and the screw rod, thus the lift tube can not rise or fall any longer, and as a result it can both ensure the use safety and timely maintenance and repair.

1, jack: adopt manual operation, not only labour intensity is big, and the safe reliability extreme difference.
2, driving: adopt driving that vehicle is sling vehicle, be placed on and carry out operation on the iron-clad horses.This kind mode of operation is time-consuming dangerous again.
3, pneumatic car lifting J-Horner; Do not have synchronously, auto-lock function, safety, reliability are very poor.
4, hydraulic pressure car lifting J-Horner: do not have synchronously, auto-lock function, maintenance load are big, and safety, reliability are relatively poor.
5, conventional electric screw jacks for lifting locomotive: have synchronously, auto-lock function, safety, good reliability.But occupy the factory building finite space, hinder the operation that repairs, displacement must be with the driving handling, and is an impediment to and realizes security civilization production.
The disclosed flush type electric screw jacks for lifting locomotive of Chinese patent ZL99254544.7, adopt the lifting tube of outside thread formula, foreign material in use are easy to fall into damage lifting tube and load-bearing nut in the screw lifting tube by thread pitch, cause stuck, and the load-bearing nut is rotation, hidden, thereby the wear pattern of load-bearing nut and the difficult discovery of fault, brought hidden danger for safety and maintenance.
Summary of the invention
The present invention seeks to overcome above-mentioned defective, a kind of flush type electric screw jacks for lifting locomotive safe and reliable to operation is provided.
Flush type electric screw jacks for lifting locomotive of the present invention comprises following constituent elements:
1) support: comprise the bearing frame of frame on combating typhoon base in ground, the bearing frame cover plate, be fixed on the sleeve that is used to help lifting tube, gear case and the reductor of bearing frame lower shoe, the driven gear and the driven wheel that are meshed are arranged in the gear case, driven gear and sleeve coaxial line, driven wheel are installed on the output shaft of reductor;
2) lifting mechanism:
Comprise the screw rod that outside coaxial line is nested with from the lining, lifting tube, rotating cylinder and bottom leak free oil tube, the dead in line of this axis and sleeve, wherein, the oil tube is fixed on the bottom of gear case, rotating cylinder places in the oil tube, device is useful on the bearing of concentric locating between the bottom of rotating cylinder and oil tube, the upper end of rotating cylinder is stretched in the gear case, the location is anchored in the axis hole of driven gear and bearing, and the lower end and the screw rod of rotating cylinder are fastening, twists on screw rod and is connected to the load-bearing nut, between load-bearing nut and lifting tube connecting key is arranged, the inwall of lifting tube has step, and step is bearing in the last plane of load-bearing nut, is provided with lock nut below the load-bearing nut, be provided with pressure sensor between lock nut and the load-bearing nut, lock nut is by key and lifting tube easy fit, and lifting tube passes through gear case, sleeve and bearing frame are with the sleeve bearing fit, outside face at lifting tube has guide surface, orienting lug is installed on the bearing frame, and orienting lug pastes mutually with the guide surface of lifting tube, is fastened with the holder head on the top of lifting tube.
When flush type electric screw jacks for lifting locomotive provided by the invention was not worked, in the lifting tube retraction support, complete machine can all be imbedded underground or below the basic plane.During use, reductor is by gear transmission driven in rotation tube and the rotation of the screw rod that is attached thereto, and at this moment, the lifting tube that is bearing on the load-bearing nut is made lifting action along orienting lug.After the wearing and tearing of load-bearing nut are shaved clearly, lifting tube is directly stressed on lock nut, at this moment, lock nut has broken away from key, causes lock nut and screw rod to dally simultaneously, and lifting tube just can not rise or fall again, simultaneously, the pressure sensor that is arranged between load-bearing nut and the lock nut gives the alarm, and has not only guaranteed safe in utilizationly, has guaranteed on-call maintenance simultaneously.
