Abstract
The utility model discloses an on-load transversal moving type support head capable of compatible to different types of railway rolling stock lifting jacks. The on-load transversal moving type support head comprises a support head (1) as well as an upper roller (2) and a lower roller (3) which are used for supporting the support head (1); the key lies in that an electric speed reducer driven by a motor is arranged at one end of the support head (1), the electric speed reducer (4) drives a lead screw (5) to rotate, and a nut (6) follows up along with the support head (1) is sleeved on the lead screw (5). The on-load transversal moving type support head has a simple structure, adopts a stable sliding screw transmission structure, the running is stable and the self-locking is easy, thereby guaranteeing the security and stability of the support head during the on-load transversal adjustment process; the compatibility is good, the operation is convenient, and the performance is stable and reliable, thereby meeting rolling stock with pad structure and vehicle holes for lifting vehicles.
Description
Technical field:
The utility model relates to rolling stock's docking facility, particularly is a kind of traversing holder head of carrying that has of railway vehicle car lifting J-Horner.
Technical background:
When railway vehicle enters shop maintenance, need it to be held up by car lifting J-Horner, so that vehicle is overhauled, and the holder head of existing car lifting J-Horner can not have the traversing action of carrying, because the leading dimensions difference of various vehicle, make the unwheeling pad of various vehicle or unwheeling hole perpendicular to the position difference on the track alignment, exist bogie truck to change the back pin, the hole contraposition is inaccurate, make car body dock problems such as difficulty with bogie truck, repair time is long, and is very inconvenient when car body and bogie truck are assembled and overhauled, inefficiency.
Summary of the invention:
Goal of the invention of the present utility model provides a kind of cross slide type holder head of carrying that has of car lifting J-Horner that can compatible different automobile types.
Realize that technical solution of the present utility model is as follows: comprise the upper roller and the bottom roller of a holder head and a support head, key is that the first end of holder is provided with motor-driven electric speed reducer, and electric speed reducer drives leading screw and rotates, a sheathed and holder Fu nut on the leading screw.
Also be provided with a big gear wheel on one end of described leading screw, big gear wheel and pinion, miniature gears is provided with the manual drives handle.
The transmitting ratio of described big gear wheel and miniature gears is 3.
The utility model is simple in structure, adopted stable slip screw drive mechanism, running steadily is easy to self-locking simultaneously, guaranteed that the holder head is having the safety and the stationarity of carrying in the horizontal adjustment process, compatible good, easy to operate, the vehicle that can satisfy the unwheeling mat structure can satisfy the vehicle in unwheeling hole again, stable and reliable for performance, applied range.
Description of drawings:
Fig. 1 is the scheme of installation of integral structure of the present utility model on car lifting J-Horner.
Fig. 2 is a structural representation of the present utility model.
The specific embodiment:
See also Fig. 1～Fig. 2, specific embodiment of the utility model is as follows: the upper roller 2 and the bottom roller 3 that comprise a holder 1 and a support 1, key is that holder 1 one end are provided with motor-driven electric speed reducer 4, and electric speed reducer 4 drives leading screw 5 and rotates, sheathed and holder 1 a Fu nut 6 on the leading screw 5; Holder 1 is made for square steel holder capitiform formula and by the double wall steel plate, holder 1 front end has a protrusion 10, unwheeling pad or unwheeling hole that holder 1 and protrusion 10 can satisfy compatible various vehicle, the upper end face of holder 1 has a upper roller 2, its rear surface has a bottom roller 3, holder 1 can be between this two roller side travel; For holder 1 can laterally be moved back and forth, set firmly a nut 6 in holder 1 bottom inner surface, leading screw 5 is placed on the nut 6, one end of leading screw 5 is connected with the electric speed reducer 4 of holder 1 one end, the screw thread of leading screw 5 and nut 6 is Acme thread, when electric speed reducer 4 work, leading screw 5 rotation makes nut 6 drive holder 1 can carry out side travel, electric speed reducer 4 is realized the coarse adjustment of holder 1 a traversing amount, electric speed reducer 4 is a maximum sideslip holder 410mm under non-unwheeling operating mode, holder 1 horizontal adjustable with suitable different vehicle; Change the back pin for solving bogie truck, the hole contraposition is inaccurate, make car body dock problems such as difficulty with bogie truck, one end of holder 1 also is provided with a big gear wheel 7 and miniature gears 8, big gear wheel 7 and miniature gears 8 engagements, big gear wheel 7 and a pair of transmitting ratio of miniature gears 8 formations are about 3 gear cluster, axostylus axostyle one end of miniature gears 8 also is provided with manual drives handle 9, make miniature gears 8 drive big gear wheel 7 and leading screw 5 rotations by shaking manual drives handle 9, thereby drive nut 6 and holder 1 is traversing, holder 1 band carries to move and is ± 25mm, holder 1 is with carries the side travel fine setting, the lateral adjustments of holder 1 can adapt to unwheeling needs of the different vehicle car body strong points, the stroke adjustment in the time of can satisfying various vehicle assembling and guarantee when non-unwheeling operating mode holder and vehicle between safety distance.
Claims (3)
1. having of rolling stock's car lifting J-Horner carried a traversing holder head, the upper roller (2) and the bottom roller (3) that comprise a holder head (1) and a support head (1), it is characterized in that holder head (1) one end is provided with motor-driven electric speed reducer (4), electric speed reducer (4) drives leading screw (5) and rotates, and leading screw (5) is gone up sheathed and holder head (1) Fu nut (6).
2. carry a traversing holder head by having of the described rolling stock of claim 1 car lifting J-Horner, it is characterized in that also being provided with a big gear wheel (7) on the end of described leading screw (5), big gear wheel (7) and miniature gears (8) engagement, miniature gears (8) is provided with the manual drives handle.
