Description

A kind of sleeper relaying machine

The utility model relates to a kind of sleeper relaying machine, belongs to the rail track maintenance of equipment.

Go forward, at home on the railway line, the replacing of existing sleeper is manually changed pillow and is done out of tradely except labour intensity is big, inefficiency, potential safety hazard are many, also use section of track machine to change sleeper.But asynchronous along with the increase of gapless track and rail and sleeper application life more just changed the hurt sleeper.So existing section of track machine can not satisfy now to rail track carry out efficiently, the requirement of rapid construction.External sleeper replacement device category is more, and the operating efficiency height that has can be changed sleeper but will remove rail; What have both can single replacing sleeper, also can change sleeper continuously, but operating efficiency was low.Therefore, be necessary prior art is improved.

The purpose of this utility model is to overcome the deficiency of prior art, and a kind of sleeper relaying machine that can efficiently carry out single sleeper replacement under the situation of not changing rail is provided.

The utility model is achieved in that it comprises vehicle frame, be located at bogie, drivers' cab, actuating unit, new sleeper feedway, old sleeper feedway, rail-lifting equipment on the vehicle frame, it is characterized in that also being provided with on the vehicle frame by mount pad, be located at the rotary extension arm on the mount pad and be located at the sleeper replacement device that the sleeper grabber on this rotary extension arm is constituted.Wherein, described mount pad comprises the base plate that is fixed on the vehicle frame, the base that can on base plate, move, be arranged on lifting, the rotation platform on the base and be located at sleeve on this platform, make mount pad forward and backwardly on vehicle frame move upper and lower lifting, or in horizontal plane, rotate, both be convenient to the sleeper replacement device and grasped new and old sleeper, being convenient to again return the vehicle to the garage and knock off after this device fulfils assignment puts in place, thereby does not influence traffic safety.Described rotary extension arm is by the guide pin bushing of being located in the mount pad sleeve and rotating around axial line, and is located at that expansion link constitutes in this guide pin bushing, so that expansion link moves horizontally in guide pin bushing.Described sleeper grabber is made of at least one group of extracting clip being located at least one group of guiding clamper on the guide pin bushing and be located on the expansion link, and each group guiding clamper with grasp clip and be on the same straight line so as to grasp synchronously, the same sleepers of clamping.Described guiding clamper comprises support, be located on the support and by the clamping bar of tensioning hydro-cylinder control and on pulley, be used for support, clamping, guiding sleeper, sleeper is moved freely thereon.Described extracting clip comprises support, is located on the support and by the chuck of tensioning hydro-cylinder control, is used to grasp the end of sleeper, so that extract old sleeper out or insert new sleeper.Also being provided with the pressure pillow device that roller is housed on its that control by oil cylinder or cylinder on the vehicle frame, when injecting the rail bottom, sleeper is flattened in addition, prevent that it is toward upwarping by it with the new sleeper of box lunch.

The utility model compared with prior art has following advantage and effect: but owing to be provided with the sleeper replacement device of a cover translation, lifting, rotation on the vehicle frame, can be under the situation that does not change the original position of rail, easily and fast, realize replacing new under the rail, old sleeper exactly, mechanized rate height not only, and it is simple in structure, easy to operate, dependable performance, can fully, rationally utilize limited circuit to repair " skylight " activity duration, therefore, be a kind of comparatively desirable sleeper relaying machine.

Fig. 1 is the combination assumption diagram of the utility model;

Fig. 2 is the sleeper replacement structure drawing of device of the utility model;

Fig. 3 is the mount pad structural representation.

Below in conjunction with accompanying drawing the utility model is described further.

Among the figure, 1 is the operation drivers' cab, 2 is hydraulic power unit, 3 is vehicle frame, 4 is new pillow conveyer belt, 5 is new pillow, 6 is rail-lifting equipment, be used for rail is mentioned specified altitude, so that the extraction of old pillow, the insertion of new pillow, 7 for pressing the pillow device, by oil cylinder or cylinder control, the one end is fixed on the vehicle frame, the other end is equipped with roller, so that sleeper is flattened, 8 is the sleeper replacement device, by mount pad 81, rotary extension arm 82, sleeper grabber 83 constitutes, the base plate 811 of mount pad is fixed on the vehicle frame 3, link to each other with base 812 by the dovetail groove on it 819, so that base 812 moves thereon, the axle 814 of elevating stage 813 is located in the axle sleeve 815 of base, so that on oil cylinder control elevating stage, move down, turntable 816 is located on the elevating stage 813 by bearing 817, so that rotate the upper end around axle 814, sleeve 818 is fixed on the turntable 816, the guide pin bushing 821 of rotary extension arm is located in the sleeve 818 of mount pad, and rotate around axial line, expansion link 822 is located in the guide pin bushing 821, and can move within it, the guiding clamper 831 of sleeper grabber is provided with two groups, one end of each pack support 832 is fixed on guide pin bushing 821 ends, the other end be connected with by the clamping bar 833 of tensioning hydro-cylinder control and on pulley 834, the extracting clip 835 of sleeper grabber is provided with two groups, an end of each pack support 836 is fixed on expansion link 822 ends, the other end is connected with the chuck 837 by tensioning hydro-cylinder control, one group of guiding clamper 831 with grasp clip 835 with in a straight line one group and constitute a sleepers is grasped, the grippers of extracting out or inserting, 9 is old sleeper, 10 is old sleeper conveyer belt, 11 is working driver chamber, 12 is actuating unit, and 13 for being located at bogie and the check mechanism under the vehicle frame, and 14 is new and old pillow conveyer.
