One end of the frame 210 passes through the through hole 220 and is caught by the roller 60. The other end of the frame 210 is connected to a frame 211a (Not shown).

Therefore, since the control body 10 and the door frame 210 are connected by the linear compensating means 50, the control body portion 10 and the door frame 210 are separated from each other by the material existing on the path through which the control body portion 10 moves. 10 or the door frame 210 can be prevented from falling in one direction and being broken.

That is, when the control body 10 is moved in the rightward direction in the drawing as shown in Fig. 7 (a) by the driving means 20, the tension roller 60 pulls the connecting line 61 while tightly pulling it, When the control unit 10 is moved in the right direction in the drawing as shown in Fig. 7 (b) by the driving means 60 as shown in Fig. 7 (b), the roller 60 pulls the connecting line 61 up It is possible to prevent the control body 10 or the door frame 210 from falling in one direction during the movement of the control body 10 or the door frame 210 and deviating from or breaking the predetermined path.

Particularly, even if the control main body 10 installed vertically to the ground inclined by the buffering means 120 is caught by this material during the straight forward and backward movement, And the control main body 10 are connected to each other, it is possible to prevent the control main body 10 or the door frame 210 from tilting in one direction to the maximum extent.

At this time, it is revealed that the buffer frame is formed at the lower end of the door frame 210 so that the door frame 210 can be vertically erected on the ground surface while cushioning the impact.

The steering means 70 is arranged so that the steering angle of the control body portion 10 connected to the door frame 210 by the linear compensation means 50 can be adjusted by the control signal of the control portion 200, (a) and (b).

The steering unit 70 is provided with a steering motor 80 which is moved to the left and right by the control signal of the control unit 200 in the control main unit 10. [

3, the rack gear 90 engaged with the steering gear 81 provided on the steering motor 80 is installed on the steering body 10, A pair of center guides 82 are vertically erected and a guide 83 having a long left and right movement holes 83 is coupled to the center guide 82.

A guide 91 penetrating through the moving hole 83 is protruded from the lower portion of the rack gear 90 so that the rack gear 90 is rotated in accordance with the steering motor 80 rotated by the control signal of the controller 200, To move leftward and rightward from the upper portion of the upper surface 83 of the housing.

3, a connection shaft 92 is connected to a lower end of the guide 91 connected to the control unit body 10 by a fixing plate 11 provided at a lower portion of the control body unit 10 and a clearance hole 131 provided at the movable plate 130 And the link 102, which is moved up and down along the connection shaft 92, is engaged.

One end of the link 102 coupled to the connection shaft 92 is coupled to the fixed shaft 103 which is vertically coupled to the steering shaft 101 to which the steering wheel 100 is coupled.

Accordingly, the steering motor 80 is rotated left and right by the control signal of the controller 200 and the rack gear 90 is moved to the left and right by receiving the rotational force of the steering motor 80, Since the steering angle of the connected steering shaft 101 is adjusted, the control body 10 can be prevented from moving out of the path in the process of being moved forward and backward by the driving means 10. [

At this time, the steering shaft 101 to which the steering wheel 100 is coupled is formed in the shape of a letter "B" bent at a right angle as shown in FIGS. 8A and 8B, The first fixing part 140 is moved up and down by the steering shaft 101 and is vertically coupled to the steering shaft 101. The link 102 is fixed to the end of the steering shaft 101 by using the fixing shaft 103 as shown in FIG. .

8 (b), the link 102, which is connected to the steering shaft 101 by the fixed shaft 103 when the steering motor 80 rotates left and right as shown in FIG. 8 (b) The steering angle of the control main body 10 can be controlled because the steering shaft 101 is rotated in the direction in which the rack gear 90 is moved around the first fixing portion 140 while moving left and right.

The fixed shaft 103 constituting the steering means 70 is fastened with bolts and nuts so as to penetrate through the elongated holes provided in the fixing plate 11, thereby facilitating the left and right movement.

The infrared sensor 191 senses direction information that the control body unit 10 can advance straight ahead while identifying the front target of the control body unit 10 and outputs the detected direction information to the control unit 200.

The sensing means 180 is not limited to the image sensor or the infrared sensor, and may be various sensors such as an acceleration sensor and a GPS sensor, which can control the direction of the target body by sensing the target.

A steam generating means 150 for removing the substance present on the path of the control main body 10 linearly moved by the sensing means 180 is installed below the control main body 10. [

The steam generating unit 150 includes a steam generator 160 for generating steam by a control signal from the controller 200 and a nozzle 162 for discharging steam generated from the steam generator 160 to the outside And the combined bracket 163 is coupled to the drive shaft 41.

The bracket 163 which is coupled to the driving shaft 41 is installed to move up and down on a connecting shaft vertically coupled to a fixing plate 11 provided at a lower portion of the control main body 10 , And the connection shaft is discharged to the outside through a clearance hole (131) provided in the movable plate (130).

Accordingly, the steam generated from the steam generator 160 is radiated to the outside through the nozzle 162 coupled to the bracket 163, so that the foreign matter placed on the ground can be removed, and the surface frozen in the cold like winter iron It can be melted.

At this time, the bracket 163 coupled with the steam generator 160 and the nozzle 162 is coupled to the connection pipe 161 having a corrugated pipe shape so that even if the driving shaft 41 is moved up and down by the buffering means 120, So that the tube 161 can be prevented from being detached from the bracket 163.

4, the damping means 120 includes a movable plate 130 spaced apart from a lower portion of a fixed plate 11 provided at a lower portion of the control body portion 10, 3, a plurality of clearance holes 131 are formed.

The shock generated during the straight running of the control main body part 10 due to the elastic force of the spring 132 is formed by connecting the fixed plate 11 and the movable plate 130 with the spring 132, ).

The fixed plate 11 provided at the lower portion of the control body 10 and the movable plate 130 coupled to the fixed plate 11 by the springs 132 are installed in the spring 132 So that the control main body 10 can be vertically installed on the ground surface inclined by the fixing portion.

The fixing part includes a first fixing part 140 vertically installed on the upper surface of the coupling part 42 provided on the steering shaft 101 and the driving wheel 40, The second fixing portion 142 is coupled to the lower portion of the control main body 10 in a vertical direction so that the lower end is coupled to the inside of the clearance groove 141 provided in the control groove.

Therefore, even if the control unit 10 is moved up and down by the fixing unit provided in the buffering means 130, the control unit 10 can be prevented from shaking to the left, right, The control unit 10 can be vertically installed on the photograph surface.

That is, even if the control body portion 10 is mounted on the spring 132 of the buffer means 120, the fixing portion composed of the first fixing portion 140 and the second fixing portion 142 can be mounted on the control body portion 10, Since the fixed plate 11 provided at the lower portion of the control unit 10 and the driving wheel 40 and the steering wheel 100 are connected to each other, even if the control unit 10 is installed on a sloping ground, It can be installed.

Since the control unit 10 is vertically erected by the fixing unit as described above, even when the folding-type door is provided on the inclined floor, the control unit 10 can be prevented from being inclined along the inclined floor Thereby preventing the control main body 10 from falling down along the inclined surface during the movement of the control main body 10 along the sloping ground surface.
