[0039] See also Figure 1-Figure 11 As shown, the present invention provides a front side anti-collision assembly for an unmanned mine car, comprising an anti-collision beam 100 installed on the front end surface of the unmanned mine car, which is fixedly connected by bolts; the anti-collision beam 100 is horizontally arranged and both ends of the front side thereof are provided with a force unloading mechanism 200 which can rotate horizontally and unload the direct impact force of the impact object, a pair of force unloading mechanisms 200 are at opposite ends and located in the middle of the anti-collision beam 100 and are in a state of being close or far, so as to form a function of guiding slag or foreign objects to the front side of the car away from the front of the car; when the mine car encounters rolling slag or foreign objects placed in front of the car during driving, the force unloading mechanism 200 changes its state to unload the impact force, thereby protecting the normal driving of the mine car;

[0040] The unloading mechanism 200 includes a pair of load-bearing rods 210 arranged in parallel with an upper and lower interval, an anti-collision net 220 that can swing downward and is arranged directly in front of the pair of load-bearing rods 210, and a unloading rod group 250 used to drive the load-bearing rods 210 located above to expand toward the inner end. The anti-collision net 220 adopts a mesh frame structure welded by steel bars. The anti-collision net 220 is used for protection. After being impacted, the bottom edge can retreat so that the anti-collision net 220 is transformed from a vertical surface to a top-view inclined surface, thereby changing the running direction of slag or foreign matter and guiding it to the ground. At the same time, since the anti-collision net 220 tilts to both sides of the mine car with the swing of the pair of load-bearing rods 210, the slag or foreign matter is guided to deviate from the front area of ​​the mine car, ensuring that the unmanned mine car has a good road condition;

[0041] The outward end of the load-bearing rod 210 located above is rotatably connected to the anti-collision beam 100, and a pair of active screw rods 120 are symmetrically coaxially arranged inside the anti-collision beam 100 and along its length direction. A forward and reverse motor 110 is installed at one end of the anti-collision beam 100, and one end of the unloading rod group 250 is threadedly connected to the active screw rod 120, and the other end of the unloading rod group 250 is rotatably connected to the inward end of the load-bearing rod 210 located above. The forward and reverse motor 110 is started to drive the pair of active screw rods 120 to rotate, driving one end of the unloading rod group 250 to move to the middle of the anti-collision beam 100, and then the anti-collision net 220 is stretched to tilt to both sides of the mine car, wherein the unloading rod group 250 uses its own elasticity to cooperate with the swing of the anti-collision net 220 to instantly change the direction of the impacting object, so that it loses its direct impact force.

[0042] Furthermore, a support frame 103 is welded below both ends of the anti-collision beam 100, and a rotating shaft 211 penetrating the vertical section of the support frame 103 is inserted between one end of a pair of load-bearing rods 210, and a circular ring is tightly sleeved at the upper and lower ends of the rotating shaft, so that the pair of load-bearing rods 210 are suspended stably;

[0043] A plurality of support rods 230 are sleeved at equal intervals on the top of the anti-collision net 220, and a plurality of spring sheets 240 are sleeved at equal intervals on the bottom of the anti-collision net 220. The outer ends of the support rods 230 and the spring sheets 240 are respectively welded to the load-bearing rods 210 located above and below. The middle part of the spring sheet 240 is in a folded convex shape. The spring sheet 240 is made of spring steel in a thin plate shape, so that the top of the anti-collision net 220 can rotate, and its bottom is in a retracted state when the spring sheet 240 is folded, forming a state of an inclined surface when the anti-collision net 220 is subjected to force.

[0044] Specifically, the unloading rod group 250 includes a support tube 251, a piston rod 252 sleeved with the support tube 251, and a threaded sleeve 254 hinged to the inner end of the support tube 251 and threadedly connected to the active screw 120. A compression spring 253 is sleeved on the outer side of the piston rod 252, and a double ring seat 2521 is welded to the outward end of the piston rod 252. A rotating shaft 211 is sleeved between the inner ends of a pair of load-bearing rods 210, and this rotating shaft 211 is sleeved with the double ring seat 2521. The upper and lower ends of this rotating shaft 211 are sleeved with circular rings. The load-bearing rod 210 is unfolded when the threaded sleeve 254 moves toward the middle of the anti-collision beam 100 and the piston rod 252 rotates.

[0045] Furthermore, the output shaft end of the forward and reverse motor 110 is coaxially connected with the driving gear 111, the forward and reverse motor 110 is installed on the front of the anti-collision beam 100, the outer end of the active screw rod 120 is tightly sleeved with the transmission gear 121 meshing with the driving gear 111, one end of the anti-collision beam 100 is provided with a rod hole 101 passing through the other end thereof, the front side surface of the anti-collision beam 100 is symmetrically provided with a slide groove 102, and the slide groove 102 is connected to the rod hole 101, and the threaded sleeve 254 is slidably connected to the rod hole 101 and the slide groove 102.

[0046] In addition, a discharge mechanism 300 is provided below the unloading mechanism 200 for discharging the fallen objects to both sides of the mine car. The impact objects discharged from the anti-collision net 220 will slide to the side of the mine car when they fall on the discharge mechanism 300, avoiding accumulation in front of the mine car.

[0047] The unloading mechanism 300 includes a baffle 310 welded to the load-bearing rod 210 located below, a supporting barrel group 320 plugged into the baffle 310 and swingable to an inclined shape, a plurality of rotatable and retractable unloading barrel groups 330 arranged inside the supporting barrel group 320, and a clamping member group 340 for positioning the inclination height of one end of the supporting barrel group 320. The axial directions of the plurality of unloading barrel groups 330 are arranged perpendicular to the front side of the baffle 310. The supporting barrel group 320 is used to support the plurality of unloading barrel groups 330 and tilt them toward the outside of the mine car, and the rolling of the unloading barrel groups 330 themselves is used to smoothly guide the fallen objects to slide away.

[0048] Specifically, the support tube group 320 includes a pair of support tubes arranged at intervals, a threaded rod 321 sleeved with the support tubes, and a pair of fixed springs 322 welded at the same ends of the support tubes. The baffle plate 310 is provided with a rotation hole 311 at the bottom corner of the outer end of the anti-collision beam 100, and a guide groove 312 is provided at another bottom corner of the baffle plate 310. The guide groove 312 is in an arc structure and its central axis is coaxially arranged with the rotation hole 311.

[0049] A pair of threaded rods 321 are respectively plugged into the rotating hole 311 and the guide groove 312, and are threadedly connected with the nut. The fixing spring 322 and the nut are respectively located at the front and rear sides of the baffle 310. The elastic force of the fixing spring 322 makes the support tube assembly 320 have an anti-impact effect, which is conducive to removing foreign objects that are originally stationary on the ground.

[0050] When installing the baffle 310, the rotating hole 311 needs to be placed outside the mine car, and the guide groove 312 needs to be placed in the middle of the front of the mine car, so as to adjust the threaded rod 321 in the guide groove 312 to rise, so that the unloading barrel group 330 is tilted toward the outside of the mine car for unloading.

[0051] Furthermore, a pair of support cylinders are welded with a straight rod between the outer ends, and straight columns are welded at equal intervals on the inner sides of the straight rods. The unloading cylinder group 330 includes a positioning cylinder 331 sleeved with the straight column, a movable cylinder 332 sleeved with the positioning cylinder 331, and a push spring 333 embedded between the ends of the positioning cylinder 331 and the movable cylinder 332. When adjusting the extension range of the support cylinder group 320, the positioning cylinder 331 and the movable cylinder 332 can also be axially extended for cooperation.

[0052] It is worth noting that the front end center of the positioning cylinder 331 is provided with an inner concave tube 3311 sleeved with the straight column, and the front end center of the movable cylinder 332 is provided with a sleeve hole 3321 sleeved with the inner concave tube 3311, so that the positioning cylinder 331 and the movable cylinder 332 rotate coaxially;

[0053] A guide column 3322 is axially extended from the rear end of the movable cylinder 332. A plurality of arc grooves are evenly spaced in front of the baffle 310 and between the rotating hole 311 and the guide groove 312. The central axes of the arc grooves are coaxial with the rotating hole 311 and the arc lengths tend to decrease toward the rotating hole 311. The guide column 3322 is correspondingly plugged into the arc grooves, so that when the lifting support cylinder group 320 is facing inward, the unloading cylinder group 330 can change its position smoothly under the guidance of the plurality of arc grooves.

[0054] In addition, a plurality of insertion holes 313 connected to the guide groove 312 are provided at the lower half of the inner end of the baffle 310, and a threaded hole 314 is provided at the upper half of the inner end of the baffle 310. The clamping assembly 340 includes a strip rod, a plurality of insertion rods 341 arranged on one side of the strip rod, and a bolt 342 sleeved on the top of the strip rod, so that the strip rod and the bolt 342 can rotate freely and be suspended at the round cap of the bolt 342. The insertion rod 341 is inserted into the insertion hole 313, and the bolt 342 is threadedly connected to the threaded hole 314. The insertion rod 341 is used to support the support tube in the support tube assembly 320 that is inserted into the guide groove 312, so that the support tube assembly 320 remains in an inclined state, and the bolt 342 is threadedly connected to the side of the baffle 310 to ensure the stability of the insertion rod 341, that is, to maintain the inclined state of the support tube assembly 320.

[0055] When the front side anti-collision assembly of the unmanned mining car of the present invention is deployed, the forward and reverse motors 110 are started to drive a pair of active screws 120 to rotate, driving the respective threaded sleeves 254 to approach the middle of the anti-collision beam 100, and then the unloading rod group 250 is gradually deployed from the horizontal orientation with the anti-collision beam 100 to the vertical orientation, thereby deploying a pair of anti-collision nets 220 in an eight-shaped shape, and then lifting the end of the support cylinder group 320 plugged into the guide groove 312, driving the unloading cylinder group 330 to tilt toward the outside of the mining car as a whole, and then re-inserting the clamping member group 340 to position the support cylinder, so that the unloading cylinder group 330 remains in an inclined state;

[0056] When the mine car encounters a foreign object that is originally stationary on the ground, the foreign object is bounced to the two sides of the mine car by using a pair of support cylinder groups 320 that are spread out in an eight-shaped shape and the elasticity of the support cylinder groups 320 themselves;

[0057] When encountering rolling slag or foreign objects placed in front of the vehicle, the anti-collision net 220 is used for protection. After being impacted, the bottom edge can retreat so that the anti-collision net 220 is transformed from a vertical plane to a downward inclined plane, thereby changing the running direction of the slag or foreign objects and guiding them to the ground. At the same time, since the anti-collision net 220 tilts to both sides of the mine car as a pair of load-bearing rods 210 swing, the slag or foreign objects are guided to deviate from the front area of ​​the mine car. If they encounter heavy objects, they will fall onto the inclined unloading barrel group 330, and the unloading barrel group 330 itself can be used to smoothly guide the fallen objects to slide away, ensuring that the unmanned mine car has a good road condition and protecting the normal driving of the mine car.

[0058] It should be noted that the above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
