Fig. 6 be small rail car of the present invention unidirectional step-by-step movement drive system in rail clamping device sectional view.
As shown in Figures 2 to 6, the present invention provides a kind of unidirectional step-by-step movement drive system of small rail car, and the track is small
Parking stall is on track, and the drive system includes a retractor device 5 and a rail clamping device, the two ends of retractor device 5
It is hinged with small rail car 100, rail clamping device respectively, the rail clamping device includes a body 1 tipped upside down on track 200,
A beloid ladder chute 11 is respectively formed between the two sides of body 1 and track 200, is respectively held in two ladder chutes 11
Receive a trapezoidal slide block 2, ladder chute 11 is fixedly arranged at the front end with front apron 4, and slidable gag lever post 6 is equipped with front apron 4,
The rear end of gag lever post 6 is fixedly connected with trapezoidal slide block 2, and the front end of gag lever post 6 is provided with the stop part that cannot pass through front apron 4.Its
In, the horizontal cross-section of ladder chute 11 and trapezoidal slide block 2 is preferably right-angled trapezium, and front apron 4 can be secured by bolts in
Body front end.Further, it is the side plate 13 on inclined-plane that body 1 has top board 12 and inner surface, and in the bottom of side plate 13
Lower baffle plate 3 is fixed with, lower baffle plate 3 can be bolted to body 1, now ladder chute 11 is by top board 12, the and of side plate 13
Lower baffle plate 3 is surrounded.The hanger 14 that is set up in parallel for a pair is also provided with body 1 and two pins of hanger 14 are arranged in
15 constituting for the articulated section that is hinged with retractor device 5.
Hereinafter, the fastening to rail clamping device is illustrated.
As shown in figure 4, when the body 1 of rail clamping device is subject to retractor device 5 backward（It is left）Active force when, rail clamping device
Body 1 move backward, so as to trapezoidal slide block 2 produce relative motion, i.e. trapezoidal slide block 2 relative to body 1 forward（It is right）Fortune
It is dynamic, because the inner surface of the side plate 13 of body 1 is inclined-plane, therefore body 1 and trapezoidal slide block 2 relative motion can make two it is trapezoidal
Spacing between sliding block 2 reduces, so that grip track 200.Clamping force after the grip track 200 of rail clamping device 5 is with retractor device 5
Put on the change of the power of rail clamping device and change, the clamping force that the bigger rail clamping device effect of power of applying is in orbit is bigger.
When the body 1 of rail clamping device is subject to retractor device 5 forward（It is right）Active force when, body 1 travels forward, so as to trapezoidal cunning
Block 2 produces relative motion, i.e. trapezoidal slide block 2 relative to body 1 backward（It is left）Motion so that between two trapezoidal slide blocks 2
Away from increasing, so as to unclamp track 200.
As shown in Fig. 4, Fig. 6, spring 8 can also be arranged with gag lever post 6, spring 8 is located at trapezoidal slide block 2 and front apron
Between 4, when drive system of the invention returns to releasing orientation from clamped condition, because spring 8 gives trapezoidal slide block 2 backward
Thrust, be thus advantageous to the reset of trapezoidal slide block 2.And external screw thread can also be respectively machined with the two ends of gag lever post 6, from
And the rear end of gag lever post 6 and trapezoidal slide block 2 are threadedly coupled, and be screwed into nut 7 to constitute stop part in front end.Now, pass through
Adjusting nut 7 can respectively adjust the ultimate range between two trapezoidal slide blocks 2 and front apron 4, it is also possible to adjust two it is trapezoidal
Maximum spacing between sliding block 2, therefore use can be adjusted such that to clamping device according to actual conditions.
Fig. 7 is sectional view when clamping section on trapezoidal slide block cross section is profiling curve.
As shown in fig. 7, when track 200 cross section both sides clamped unit 201 be curve when, trapezoidal slide block 2 it is transversal
Clamping section 21 on face can also be corresponding profiling curve, and this facilitates gripping by the relatively reliable grip track of device.
Hereinafter, to the operation principle of unidirectional step-by-step movement drive system of the invention is illustrated.
With reference to shown in Fig. 2, Fig. 4, rail clamping device is placed on the front of small rail car 100（Right）Track on.First, when stretching
When compression apparatus 5 extend, the body 1 of rail clamping device is promoted forward（It is right）Motion causes that rail clamping device returns to release from clamped condition
State, because the frictional force between the lighter in weight of rail clamping device, with track 200 is smaller, therefore, the elongation of retractor device 5, meeting
Rail clamping device is driven integrally to travel forward, now due to the limitation of the stop part with gag lever post 6, therefore trapezoidal slide block 2 will not
Skidded off from the rear of body 1, and the then remains stationary in the presence of frictional force of small rail car 100；Afterwards, retractor device 5 starts
Shrink, pull the body 1 of rail clamping device backward（It is left）Motion so that rail clamping device is changed into clamped condition from releasing orientation, also
It is to say, now rail clamping device forms static on track 200, and the contraction of retractor device 5, small rail car 100 can be driven forward
（It is right）Motion.So move in circles, it is possible to drive small rail car 100 along track stepping forward.When need to make small rail car to
After when moving, only rail clamping device need to be placed on the rear of small rail car 100（Left）Track on.
It should be noted that the small rail car in the present invention not only includes being used to load the dolly of goods on track, and
Also including the device moved by track etc..
In sum, the unidirectional step-by-step movement drive system of small rail car of the invention is by between two trapezoidal slide blocks of change
Spacing to clamp or unclamp track, by the cooperation of retractor device and clamping device to realize unidirectional stepping, so that this is unidirectional
Step-by-step movement driving system structure is simple, easy to use, and is favorably improved efficiency and reduces cost.So, the present invention has
Effect overcomes various shortcoming of the prior art and has high industrial utilization.
The above-described embodiments merely illustrate the principles and effects of the present invention, not for the limitation present invention.It is any ripe
The personage for knowing this technology all can carry out modifications and changes under without prejudice to spirit and scope of the invention to above-described embodiment.Cause
This, those of ordinary skill in the art is complete with institute under technological thought without departing from disclosed spirit such as
Into all equivalent modifications or change, should be covered by claim of the invention.
