Abstract

The utility model relates to a diesel engine lift and turnover device for disassembly and assembly of the diesel engine of a locomotive, comprising a rolling support, a front rotary disc and a back rotary disc; the front rotary disc and the back rotary disc are arranged on the roller of a lifting platform. Two main beams are fixedly connected between the two rotary discs, the front rotary disc is in a joint structure of two half circular rings, and the two circular rings are connected to integration by a hinge and a locking apparatus. The carriage disassembly and assembly of the entire locomotive diesel engine and a main generating set can be conducted by the utility model, and the length of the elevating platform and the turnover device is reduced. Thus the equipment cost is reduced, and the use is convenient.

Description

Folding lift and turnover device for diesel engine of locomotive

The utility model relates to and a kind ofly is used for that diesel engine of locomotive disintegrates and stack-mounted diesel engine lifting turning rack, particularly a kind of being used for whole diesel engine of locomotive-main generator group put on the shelf disintegration and stack-mounted lifting turning rack.

Diesel engine of locomotive disintegrate and assembling operation in, for ease of operating, diesel engine need be risen, descends or rotate to certain angle.In the prior art, existing bay-lift and turning rack are combined into one, constitute diesel engine lifting turning rack, it includes the preceding rotating disk of rolling bearing on the bay-lift roller and back rotating disk, two girders of captive joint between two rotating disks.Diesel engine is fixed on two girders, and lifting and rotating disk by bay-lift rotate on roller, can realize the lifting and the upset of diesel engine.Disintegrate and assembling as if whole diesel engine of locomotive-main generator group is put on the shelf, the length of just essential extend bay-lift and turning rack increases cost of equipment.

The purpose of this utility model is to provide a kind of improved diesel engine lifting turning rack, whole diesel engine of locomotive-main generator group can be put on the shelf to disintegrate and assembling, need not the length of bay-lift and turning rack that extends, thereby significantly reduces cost of equipment.

For achieving the above object, the utility model adopts following technical proposals: the same preceding rotating disk and the back rotating disk that is supported on the bay-lift roller, two girders of captive joint between two rotating disks of including with prior art of this diesel engine lifting turning rack.Be characterized in: preceding rotating disk is two involutory structures of semicircular ring, and two semicircular ring are linked into an integrated entity by hinge and locking device.During use, untie the locking device earlier, translation frame under the upper semi-circle hoop is fixed whole diesel engine of locomotive-main generator group handling then to turning rack.Rotating disk is a semicircle before this moment, can hold main generator on it.After main generator was removed, the semicircular ring of turning over was upwards turned over and synthetic full circle ring down, locks the locking device, just can carry out turning operation.

The utility model compared with prior art, have advantage as described below: this lifting turning rack can be put whole diesel engine of locomotive-main generator group on the shelf and be disintegrated and assembling, reduce the length of bay-lift and turning rack, thereby significantly reduce cost of equipment, it is also convenient to use.

The drawing of accompanying drawing is described as follows:

Fig. 2 is an A-A place cutaway view among Fig. 1.

Fig. 3 is the structural representation of locking device.

Fig. 4 is the cutaway view at B-O-B place among Fig. 3.

Fig. 5 and Fig. 6 are the structure principle charts (constitution diagram when Fig. 5 threads off for the locking device, constitution diagram when Fig. 6 is locking device hook) of locking device.

Lateral plan when Fig. 7 is the synthetic full circle of two semicircular ring of preceding rotating disk.

Fig. 8 is the following lateral plan during upset of first annulus of preceding rotating disk.

An optimum implementation of the present utility model is: referring to Fig. 1, Fig. 2, Fig. 7 and Fig. 8, this diesel engine lifting turning rack includes rolling bearing two girders 6 of captive joint between the preceding rotating disk on the bay-lift roller 12 and back rotating disk 7, two rotating disks 2,7.Before rotating disk 2 be to constitute by two semicircular ring 4,8 are involutory, two semicircular ring 4,8 are linked into an integrated entity by hinge 3 and locking device 5.Referring to Fig. 3 and Fig. 4, the structure of locking device 5 is: the eccentric axle bed (12) of captive joint on a semicircular ring 4, normal-running fit one eccentric shaft 13 in the axis hole of eccentric axle bed 12, a be rotationally connected respectively end of two connecting rods 14, the two ends of eccentric shaft 13, the other end of connecting rod 14 hanging scroll 16 that is rotationally connected, handle 9 of the middle part captive joint of eccentric shaft 13, there is individual handle lock 10 outer end of handle 9; Captive joint hook base 17 on another semicircular ring 8 has a hook 18 to cooperate with hanging scroll 16 hooks on the hook base 17.For eccentric axle bed 12 and hook base 17 joints are joined with engaging tooth 15 engagements.Referring to Fig. 5 and Fig. 6, the principle of work of locking device 5 is: when handle 9 was swung to the right, the axle center of eccentric shaft 13 moved to right, and what is that hanging scroll 16 is threaded off with hook 18, and locking device 5 is opened (shown in Figure 5); When handle 9 was swung left, the axle center of eccentric shaft 13 moved to left, and what is that hanging scroll 16 is hooked in hook 18, locking device 5 lockings (shown in Figure 6).Referring to Fig. 7 and Fig. 8, a rubber buffering boss 19 is arranged on the side of the installation hinge 3 of a preceding rotating disk 2-semicircular ring 4, this rubber buffering boss height is identical with the height of hinge 3.When 4 times upsets of first annulus, rubber buffering boss 19 contacts the damage in order to avoid two semicircular ring 4,8 collide with second annulus 8.
