The utility model can vertically lift the oil cylinder and does not expose the pit after lifting; without projections on the ground after landing, the vertical lifting device facilitates the maintenance of vehicles and ensures the security; compared with the overturn type, the lifting device has swift action, firm lock, as well as easy installation and maintenance, which can be used for the maintenance operations of a variety of locomotives and vehicles.
Description
One, technical field
The utility model relates to car lifting J-Horner, specifically relates to a kind of vertical lift device of concealed car lifting J-Horner.
Two, background technology
Car lifting J-Horner is a kind of lifting equipment that uses when car inspection and maintenance, because of its purposes difference is divided into automobile car lifting J-Horner and locomotive car lifting J-Horner.
The car lifting J-Horner that is used for railway locomotive, its lifting device are to be made of several oil cylinder groups that are fixed on the railway both sides, each oil cylinder group synchronization action under the control of hydraulic power unit, thus locomotive is lifted.In order to keep the clean and tidy of operation place,, the car lifting J-Horner that has can be hidden in each oil cylinder group when not working in separately the melt pit, and this kind car lifting J-Horner is called concealed car lifting J-Horner.
Existing concealed car lifting J-Horner all adopts the device of rollover when the hoist cylinder group, it is in the bottom of oil cylinder group several hinges to be set, and in the side of oil cylinder group a pipe bending cylinder is installed, and makes the upset of oil cylinder group by the expanding-contracting action of pipe bending cylinder.Because pipe bending cylinder is by hydraulic-driven, many hydraulic tubings must be installed, so installation difficulty is big, operational failure rate height, oil cylinder group are difficult to keep synchronously more for a long time, and especially this car lifting J-Horner exposes melt pit after rising, not only influence upkeep operation, and exist potential safety hazard.
Three, summary of the invention
In order to solve the problems referred to above that existing concealed car lifting J-Horner exists, the utility model provides a kind of vertical lift device of concealed car lifting J-Horner, and it can vertically hold out ground with oil cylinder, and can keep levelling of the land.
The technical solution of the utility model is as follows:
A kind of vertical lift device of concealed car lifting J-Horner, comprise guide frame, alighting gear, lifting mechanism and catch gear, described guide frame is vertically mounted in the melt pit, alighting gear is slidingly installed in guide frame, described lifting mechanism is made up of screw rod of erectting and the electrical motor that is sleeved on the change speed gear box on the screw rod and be fixed on the change speed gear box, the bottom of this screw rod is connected with the base plate rigidity of guide frame, the outside thread sliding block joint of the negative thread of change speed gear box and screw rod, the shell of change speed gear box is captiveed joint with alighting gear, makes change speed gear box drive alighting gear under the driving of electrical motor and moves up and down; Described lockout mechanism is made up of electrical motor, leading screw, driver and lock pin, this lockout mechanism is fixedly mounted on the alighting gear, the power of electrical motor passes to leading screw through driver, simultaneously rotatablely moving of motor is become the straight-line motion of leading screw, drives lock pin by leading screw and moves axially; The side of described alighting gear and the top of guide frame are provided with transverse concave groove, and when alighting gear rose to the desired location, lock pin inserted in this groove, is locked.
On the described alighting gear hydraulic ram is housed, it can follow together lifting of alighting gear.
The vertical lift device of concealed car lifting J-Horner described in the utility model can vertically be held out ground with hydraulic actuating cylinder, does not expose melt pit after the rise, and ground, landing back does not have ridge, both has been convenient to maintenance activity, has eliminated potential safety hazard again.Especially this jacking system is a driven by power, and mechanical caging is compared with hydraulic overturn, is swift in motion, and locking firmly is convenient to installation and maintenance.
Four, description of drawings
Fig. 1 is a kind of structural representation of vertical lift device of concealed car lifting J-Horner.
Fig. 2 is by left view shown in Figure 1.
Five, the specific embodiment
Referring to Fig. 1, a kind of vertical lift device of concealed car lifting J-Horner comprises guide frame 2, alighting gear 3, lifting mechanism and lockout mechanism.
Lifting mechanism is made up of screw rod of erectting 7 and the electrical motor 5 that is sleeved on the change speed gear box 6 on the screw rod 7 and be fixed on the change speed gear box.The bottom of screw rod 7 is connected with the base plate of guide frame 1 rigidity, the outside thread sliding block joint of the negative thread of change speed gear box 6 and screw rod 7, and the shell of change speed gear box 6 is captiveed joint with alighting gear 3.Change speed gear box 6 drives alighting gear 3 and moves up and down under the driving of electrical motor 5.
Referring to Fig. 2, lockout mechanism is by electrical motor 8, driver 9, and leading screw 10 and lock pin 11 are formed.This lockout mechanism is fixedly mounted on the alighting gear 3, and the power of electrical motor 8 passes to leading screw 10 through driver 9, and rotatablely moving of electrical motor 8 become the straight-line motion of leading screw 10, drives lock pins 11 by leading screw 10 and moves axially.
Be provided with transverse concave groove 12 in the side of alighting gear 3 and the top of guide frame 2, when alighting gear 3 rising desired locations, in lock pin 11 insertion grooves 12, with alighting gear 3 lockings.
