The specific embodiment

Knot accompanying drawing instance elaborates to the utility model below:

As shown in Figure 1, the said Railway Special of the utility model pulls machine, and complete machine mainly is made up of 2 two parts of assembly 1 and undercarriage assembly of putting on the shelf; The assembly 1 of wherein putting on the shelf constitutes as shown in Figure 2; Comprise upper spider 9, power set, check mechanism, transmission joint, operation handrail 7 and electric control gear, said power set, check mechanism, transmission joint connect fixing and upper spider 9 relevant positions successively, and link to each other with electric control gear; The operation handrail is fixed on upper spider one end; The upper spider center is provided with rotating disk and rolling bearing, and said transmission device comprises disc type freewheel clutch 5, reductor 6, cable drum and wire rope 8, top sheave support 10, and top sheave support 10 is fixed in the opposite end of operation handrail 7 on the upper spider; Wire rope one end is fixed in reel, and the other end is provided with the hook that is connected with railroad tie.The assembly of putting on the shelf is mainly system works and power is provided and pulls Job Operations; Wherein freewheel clutch adopts tray type structure; Be in order to realize the layout needs in short space; This freewheel clutch can change the size of carry-over moment through its amount of spring compression of adjustment, and main effect is to prevent to damage system architecture under the seriously overload situation.

Undercarriage assembly 2 constitutes as shown in Figure 3, comprises lower bearing bracket 11, wheel 13, retaining mechanism 12, and it is supporting slip ring 15 and rotating shaft 16 that lower bearing bracket 11 centers are provided with upper spider 9 corresponding rotating mechanisms; Supporting slip ring 15 and rotating shaft 16 respectively with upper spider in rotating disk and bearing cooperate; After put on the shelf assembly and the aggregate erection of undercarriage assembly, the assembly of putting on the shelf can be realized the operation that pulls of 360 any directions around the rotation of the rotating shaft on the undercarriage assembly; Said supporting slip ring also can be used for the supplemental support except that rotating shaft; Bow when preventing the upper bracket heavy duty, can reduce rotating shaft wearing and tearing in use simultaneously, said wheel and retaining mechanism are installed on the bottom surface and the side at 11 4 angles of lower bearing bracket respectively; Make complete machine be implemented in rail upper edge track travel through four wheels 13; Be implemented in the fixing of a certain position on the rail through four locking drag hooks 12, complete machine moves or tumbles when avoiding pulling operation, also is provided with the lower sheave bracket assembly 17 of a movable connection simultaneously in the undercarriage assembly; Plug in construction is adopted in its end; Lower bearing bracket 11 two ends all are provided with corresponding insertion mouth 14, make lower sheave bracket assembly 17 can insert arbitrary end quickly and easily and insert mouth 14, to realize pulling sleeper from arbitrary limit on railway both sides.
