Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lifting traverser mainly used for maintenance and repair of bogies, wheels and underfloor equipment of railway vehicles.

[0002]

2. Description of the Related Art When trolleys, wheels, etc. of railway vehicles are inspected or repaired at a maintenance shop, as shown in FIG.
A groove B extending in the direction intersecting with the groove B is dug and formed, and the truck C1 of the vehicle C is pulled out downward by the lifting traverser 50 provided in the groove B, and the lifting traverser 50 is laterally moved in the groove B. Move the transfer path A
The trolley C1 is replaced on the repair rail D extending in parallel with the trolley C for repair.

The conventional lifting traverser 50 has a base 51 movably mounted on a lateral movement rail B1 formed on the bottom surface of the slot B, and an elevating table 53 having a transfer rail 52 laid on the upper surface thereof. It is configured to be supported by four screw shafts 54. By rotating the four screw shafts 54 at a constant speed, the elevating table 53 is raised so as to be flush with the transfer path A, and then the vehicle C is moved. The vehicle C is supported by the jacks E at both sides of the slot B while the vehicle C1 is moved and placed on the lift table 53, and the lift table 53 is lowered in this state to move the carriage C1. The lifting traverser 50 is removed from the vehicle C, and then the lifting traverser 50 is laterally moved to a position of the repair rail D.

[0004]

In this prior art, the screw shaft 54 is used as the raising and lowering means of the lift table 53 when the vehicle C is moved between the transfer path A and the lift table 53. This is to prevent the lifting platform 53 from sinking due to the weight of C, so that the vehicle C can be safely replaced between the transfer path A and the lifting platform 53. However, (1). The structure for rotating the four screw shafts 54 at a constant speed is complicated, and it takes time to maintain and inspect the lifting traverser 50. (2). The base body 51 has four screw shafts. Since the vertical height of 54 is required to move up and down, not only the lifting traverser 50 becomes bulky but also the depth of the groove B becomes deep, which increases the cost of installation work. (3) Screw With the lifting means using the shaft 54, the lifting speed of the lifting table 53 is slow, so the work efficiency is poor. (4). The left and right side edges of the lifting table 53 are overhung outside the lateral movement rail B1. In addition, since the lifting traverser 50 is bulky as described above, the stability of the lifting table 53 in a raised state is poor, and therefore the vehicle C passes between the transfer path A and the lifting table 53. The phenomenon that the lift 53 tilts every time Occur, it is not possible to drive the vehicle C to necessarily smooth, there is a problem that said the.

An object of the present invention is to provide a lifting traverser that solves these problems.

[0006]

In order to achieve this object, the present invention is directed to "a transfer path of a vehicle is formed by forming a groove hole extending in a direction intersecting with the transfer path and laying on the bottom surface of the groove hole. A base body is movably mounted on the laterally moving rail, and an elevating platform for mounting a carriage or the like of the vehicle on the base body can be raised to a height position that is flush with the transfer path. In a lifting traverser provided so as to be movable up and down, the lifting table is vertically movably attached to the base body via a fluid pressure cylinder such as a hydraulic cylinder, and both left and right sides of the lifting table extending in the traveling direction thereof. A lock member that is capable of projecting laterally toward the outside of the elevator and is not movable up and down is provided at the portion of the above position, while a lock member that horizontally protrudes from the elevator at the elevated position is provided at the portion of the inner surface of the slot. versus And the configuration of that provision of the support ".

[0007]

With the above construction, by using a fluid pressure cylinder such as a hydraulic cylinder as the lifting means of the lifting table, the lifting speed of the lifting table is remarkably higher than that of the conventional screw type jack. Since it can be improved, work efficiency can be significantly improved. In addition, with the lifting table raised, the lock member is projected laterally,
By being supported by the support portion provided on the inner side surface of the slot, the lift table is in the same state as being fixed to the floor of the transfer path, so that the lift table can be moved up and down at high speed by the fluid pressure cylinder. In spite of this, it is possible to prevent the elevator from tilting at the time when the vehicle moves between the transfer path and the lift table, and thus, to prevent the vehicle from moving between the lift table and the transfer path. The transition can be performed smoothly and safely without rattling.

Therefore, the present invention has an effect that the vehicle can be smoothly and safely relocated between the elevator and the transfer path and the work efficiency can be improved. Further, since the lifting table is moved up and down by the fluid pressure cylinder, it is possible to simplify the structure for moving the lifting table up and down as compared with the conventional one in which a plurality of screw shafts are rotated at a constant speed. Have.

Further, according to the second aspect of the present invention, since the hydraulic cylinder is in the inclined posture, the height of the lifting traverser can be reduced, so that the whole can be made compact and the stability can be further improved. In addition, since the overall volume can be reduced and the depth of the slot can be reduced, the cost of installation work can be reduced.

As shown in FIGS. 6 and 8, the base body 2 is formed with a notch hole 27 into which the lower portion of the lifting hydraulic cylinder 24 is inserted. Left and right link mechanism 7
Lower support shaft 13 fixed between the lower ends of the front and rear inner arms 8 at
Are linked by parallel links 28. Therefore, the left and right link mechanisms 7 operate in exactly the same manner even though they are individually driven by the lifting hydraulic cylinders 24.

A pair of transfer rails 29 are laid on the upper surface of the lift table 3 at the same intervals as the rail A1 of the transfer path A. In addition, the lifting table 3 is formed in a hollow shape, as shown in FIG.
As shown in FIG. 11, two lock members 30 are provided at the left and right ends of the frame body 3a of the lifting table 3 between the front and rear transfer rails 29 and extend in the same direction as the transfer rails 29. Is attached so as to be slidable laterally via a holding member 31, the base ends of the front and rear lock members 30 are fixed to one fourth bracket 32, and the fourth bracket 32 is
The tip of the piston rod 33a of the lock hydraulic cylinder 33 provided on the frame 3a is fixed by a vertically extending pin 34.

Therefore, by operating the lock hydraulic cylinder 33, the front and rear lock members 30 can be laterally projected and retracted from the lift 3. As shown in FIG. 11, a liner 35 is fixed to the inner surface of the holding member 31, and an oiling hole 35 for supplying lubricating oil is formed in the inner surface of the liner 35. The oiling holes 35 at the front and rear side surfaces and the lower surface of the holding member 31 communicate with each other through communication holes 37.

At both the left and right sides of the upper inner surface of the slot B, which are sandwiched by the front and rear rails A1 of the transfer path A, a step portion is provided so that the lock member 30 can be protruded while the lift table 3 is raised. B2 is formed, and a metal plate supporting member 38 for the lock member 30 is fixed to the step B2. A plate 39 made of a hard metal material such as a hardened steel plate is fixed to a portion of the support member 38 that comes into contact with the lock member 30.

A pair of front and rear guide rollers 40 that rotatably contact the front and rear side surfaces of the protruding lock member 30 are attached to the support member 38 via a fifth bracket 41 so as to be horizontally rotatable. The tip end portion of the lock member 30 is formed in a tapered shape in a plan view so that the front and rear guide rollers 40 can be smoothly fitted into each other, and as shown in FIG. The lower end of the tip of the is cut obliquely so that the sliding movement onto the support member 38 can be performed smoothly.

Further, the support member 38 is provided with a sensor (limit switch) 42 for detecting that the lock member 30 is projected. Although not shown, the base body 2 includes the lifting hydraulic cylinder 2

Further, although not shown, a sensor for detecting the rising position of the lifting table 3 is provided in the lifting table 3 or the groove B, and the lifting of the lifting table 3 and the base body 2 are performed through these sensors. It is designed to control driving and the like.

In the above structure, the lifting hydraulic cylinder 24 is operated to raise the lifting platform 3 so as to be flush with the transfer path A, and then the locking cylinder 33 is operated to project the locking member 30. Then, the left and right four lock members 30 are respectively supported by the support members 39 of the slot B. As a result, since the lifting platform 3 is supported at both left and right ends while straddling the slot B, the carriage C1 of the vehicle C can be moved onto the lifting platform 3 without play.

When the carriage C1 of the vehicle C arrives at a predetermined position on the lift table 3, the transfer of the vehicle C is stopped, and then, as shown in FIG.
Similarly to (a), the vehicle C is supported by the jack E, the lock member 30 is retracted in that state, and then the lift 3 is lowered. Then, the pin C2 protruding upward from the carriage C1
(See FIG. 1) is removed from the body of the vehicle C,
1 is removed from the car body.

When the lifting table 3 is completely lowered, the base body 2 is laterally moved to the position of the repair rail D, and the lifting table 3 is lifted at that position, so that the carriage C1 is replaced with the repair rail D. The vehicle C1 can be assembled to the vehicle C by carrying out repairs and inspections, and then transporting the vehicle C1 in the reverse order to the above after repairs and inspections. As described above, since the lifting / lowering table 3 is lifted / lowered by the lifting / lowering hydraulic cylinder 24, the lifting / lowering table 3 can be lifted and lowered at a high speed, and thus the working efficiency can be remarkably improved. Further, since the lock member 30 is provided, the lift table 3 can be held in a stable state at the lifted position, so that the vehicle C is provided between the lift table 3 and the transfer path A.
There is almost no rattling at the time of shifting, and the traveling of the vehicle C between the transfer path A and the lift 3 can be performed smoothly and safely.

Further, by mounting the lifting table 3 via the link mechanism 7, the lifting hydraulic cylinder 24 can be arranged in an inclined posture, so that the overall volume can be reduced and the size can be reduced. As a result, it is possible to reduce the depth of the groove B to reduce the installation cost. When the support member 39 is provided with the guide roller 40 for guiding the lock member 30 as in the embodiment, the transfer rail 29 of the lifting platform 3 is positioned so as to extend in a straight line with the rail A1 of the transfer path A. There is an advantage that can be.

In the present invention, the lock member is not limited to the prismatic shape, but may be another shape such as a cylindrical shape. Needless to say, the means for projecting the lock member is not limited to the hydraulic cylinder as in the embodiment, and other means such as a pneumatic cylinder or an electromagnetic solenoid may be adopted. Further, the fluid pressure cylinder for moving up and down the lift may be a pneumatic cylinder.

Although the above-mentioned embodiment is applied to the lifting traverser for pulling out the bogie of the railway vehicle, the present invention can be applied to other uses.
