DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-8 This application is described in further detail.

[0032] The embodiment of the present application discloses a mountain all-terrain transportation system.

[0033] Reference Figure 1 and Figure 2 The mountain all-terrain transportation system includes a transport vehicle and a track 2. The transport vehicle includes a driving mechanism 1, a pallet 3, a bearing plate 4, a wheel seat 5, a sliding mechanism 6, and a counterweight mechanism 7. The track 2 is laid and installed along the mountain transportation route. The driving mechanism 1 is an engine commonly used in existing rail transport machines, and is fixedly connected to the wheel seat 5 by a rope, thereby driving the wheel seat 5 forward. The sliding mechanism 6 is a roller commonly used in mountain rail transportation and a tooth structure matched on the track 2. The sliding mechanism 6 is installed on the wheel seat 5, so that the sliding mechanism 6 is slidably connected to the track 2. The wheel seat 5 is rotatably connected to the lower surface of the pallet 3 through a bearing support. The bearing plate 4 is arranged above the pallet 3, and the counterweight mechanism 7 is arranged between the bearing plate 4 and the pallet 3.

[0034] Reference Figure 1 and Figure 2 The counterweight mechanism 7 includes two pressure detection units 71, a counterweight block 72 and an adjustment mechanism 73. In the present embodiment, the pressure detection unit 71 is a pressure sensor. The two pressure detection units 71 are installed on the upper surface of the support plate 3. The two pressure detection units 71 are distributed on both sides of the center of the support plate 3 and are used to detect the pressure changes on both sides of the center of the support plate 4. The detection end of the pressure detection unit 71 is fixedly attached to the lower surface of the support plate 4. The two pressure detection units 71 can respectively detect the pressure on both sides of the support plate 4.

[0035] The transport vehicle is equipped with a controller, which is electrically connected to the pressure detection unit 71 and the adjustment mechanism 73 and is configured to: based on the detection values ​​fed back by the two pressure detection units 71, the adjustment mechanism 73 is activated and the center of gravity of the transport vehicle is balanced, which will be described in detail later. Figure 1 Vertical side plates 31 are welded at the front and rear ends of the support plate 3, and vertical baffles 32 are welded on both sides of the support plate 3. A deformable structural piece 33 is bonded to the upper end of the baffle 32, and the upper end of the deformable structural piece 33 is bonded to the lower surface of the bearing plate 4. The deformable structural piece 33 is made of a flexible rubber sheet and can be deformed, thereby not only reducing dust and rainwater from entering the support plate 3 and protecting the pressure detection unit, but also not affecting the longitudinal displacement of the bearing plate 4; secondly, a gap is left between the side plate and the bearing plate, so as not to interfere with the longitudinal displacement of the bearing plate.

[0036] Reference Figure 2 and Figure 3 The adjustment mechanism includes a motor 731 and a lead screw 732. The length direction of the lead screw 732 is perpendicular to the extension direction of the track 2, and the lead screw 732 is rotatably connected to the baffle 32 through a bearing. The motor 731 is fixedly mounted on the upper surface of the support plate 3 through a nut. The output shaft of the motor 731 is coaxially fixed with one end of the lead screw 732, and the counterweight 72 is threadedly connected to the lead screw 732. The baffle 32 is provided with a limiting assembly 75 for limiting the counterweight 72. The limiting assembly 75 includes a limiting plate 751 which is horizontal and located above the counterweight 72. The two ends of the limiting plate 751 are respectively welded between the two baffles 32, and the lower surface of the limiting plate 751 is attached to the upper surface of the counterweight 72.

[0037] Reference Figure 2 and Figure 4 Considering that directly throwing the goods onto the load-bearing plate 4 during loading may damage the pressure detection unit 71, a buffer mechanism 74 is also provided on the load-bearing plate 3. The buffer mechanism 74 includes a buffer spring 741, an outer rod 742 and an inner rod 743. The outer rod 742 is welded to the load-bearing plate 3. The outer rod 742 is hollow inside and the upper end is open. The inner rod 743 is slidably penetrated in the open inner cavity of the outer rod 742, and the upper end of the inner rod 743 is fixedly connected to the lower surface of the load-bearing plate 4. The buffer spring 741 is sleeved on the outside of the outer rod 742, and the upper end of the buffer spring 741 abuts against the lower surface of the load-bearing plate 4, and the lower end abuts against the upper surface of the load-bearing plate 3.

[0038] In order to limit the pressure detection unit 71, a limit spring 744 is arranged in the inner cavity of the outer rod 742, and the lower end of the limit spring 744 abuts against the bottom surface of the inner cavity of the outer rod 742, and the upper end of the limit spring 744 abuts against the lower surface of the inner rod 743. The length of the inner rod 743 is greater than the length of the outer rod 742. Therefore, when the limit spring 744 abuts against the inner rod 743 so that the inner rod 743 is subjected to pressure, the upper end of the inner rod 743 is always higher than the upper end of the outer rod 742. When the pressure detection unit 71 is continuously subjected to pressure, the inner rod 743 gradually presses against the limit spring 744 until the limit spring 744 is compressed to the shortest, and the inner rod 743 cannot continue to slide downward. At this time, the pressure applied to the pressure detection unit 71 does not exceed the critical value of its measuring range, so that the limit spring 744 serves to limit the pressure detection unit 71.

[0039] In this embodiment, in the initial state, the counterweight 72 takes the center of the lead screw 732 as the zero point. When the pressure detection unit 71 outputs a detection signal to the controller, the controller compares the pressure values ​​output by the two pressure detection units 71, and then determines which side the center of gravity of the load-bearing plate 4 is offset to, and then the controller controls the motor 731 to drive the lead screw 732 to rotate forward or reverse, so as to drive the counterweight 72 to move and adjust the center of gravity of the transport vehicle. It is understandable that, because the limit plate 751 fits with the counterweight 72, under the limiting effect of the limit plate 751, the counterweight 72 cannot rotate with the lead screw 732, so as to realize the forward and reverse operation of the motor 731 to control the counterweight 72 to move left and right, so as to achieve the effect of balancing the load-bearing plate 4 and reduce the probability of the transport vehicle rolling over.

[0040] Reference Figure 1 and Figure 5When transporting goods on a rugged and inclined section of a mountain road, the load-bearing plate 4 may tilt to one side along with the track 2. At this time, the pressure detection unit 71 cannot correctly detect the pressure distribution on the upper surface of the load-bearing plate 4 when it is tilted. The load-bearing plate 4 needs to be kept relatively horizontal before the goods are transported. Therefore, the system also includes a support mechanism 8 and a clamping mechanism 9, wherein the support mechanism 8 includes four hydraulic cylinders 81 and a sliding block 82. The four hydraulic cylinders 81 are evenly distributed on both sides of the track 2, so that the hydraulic cylinders are fixedly installed on the side walls of the wheel seat respectively, and the hydraulic cylinders are tilted and their output shafts are arranged obliquely upward. The output shaft of the hydraulic cylinder 81 is hinged to the sliding block 82. Sliding grooves 83 for sliding connection of the sliding block 82 are respectively provided on both sides of the pallet 3. The opening direction of the sliding groove 83 is perpendicular to the extension direction of the track 2. By controlling the extension and retraction of the hydraulic cylinders 81 on both sides of the wheel seat 5, the hydraulic cylinders 81 drive the sliding block 82 to slide, so as to adjust the horizontality of the pallet 3, and finally make the supporting plate 4 reach a horizontal state on the left and right. After that, the goods are placed on the supporting plate 4, and the position of the counterweight block 72 is adjusted. After that, the hydraulic cylinder 81 is returned to its position, and the pallet 3 is clamped and positioned through the clamping mechanism 9 to prevent the pallet 3 from swinging during transportation.

[0041] Reference Figure 3 and Figure 6 The clamping mechanism 9 includes four wedge blocks 91 and a linkage assembly 92. The four wedge blocks 91 are evenly distributed on both sides of the wheel seat 5. The middle bottom of the support plate 3 is arranged in an arc-shaped protrusion, and the wedge block 91 is located between the support plate 3 and the wheel seat 5. At the same time, the lower surface of the wedge block 91 contacts the upper surface of the wheel seat 5, and the inclined surface of the wedge block 91 faces the arc-shaped protruding surface of the support plate 3. The linkage assembly 92 is connected to the side plate 31.

[0042] Reference Figure 6 , Figure 7 as well as Figure 8 The linkage assembly 92 includes a lifting rod 921, a fixed shaft 922, a connecting rod 923 and a connecting assembly 93. The fixed shaft 922 is parallel to the support plate 3 and is rotatably connected to the connecting rod 923 through a bearing. The two sides of the support plate 3 are respectively provided with sliding grooves 34 for the wedge block 91 to slide through along the width direction of the support plate 2. The upper end of the wedge block 91 is provided with a sliding groove 34 extending out, and the upper end of the wedge block 91 is hinged to one end of the connecting rod 923 away from the fixed shaft 922. The side plate 31 is provided with a connecting groove 1 924 and a connecting groove 2 925. The connecting groove 1 924 is provided in the longitudinal direction, and the connecting groove 2 925 is provided on the side of the connecting groove 1 924 away from the wheel seat 5. One end of the connecting groove 2 925 is connected to the connecting groove 1 924, and the other end of the connecting groove 2 925 is bent downward and extended. The lifting rod 921 is arranged on the side of the side plate 31 away from the supporting plate 3, and one end of the fixed shaft 922 away from the connecting rod 923 is passed through the connecting groove 1 924 and fixedly connected to the lower end of the lifting rod 921.

[0043] The connecting assembly 93 is arranged on the side of the side plate 31 away from the support plate 3. The connecting assembly 93 includes a positioning block 931 and a fixing column 932. The positioning block 931 is welded to the lower end of the side plate 31. The positioning block 931 is hollow inside and has an opening at the upper end. The two side walls of the positioning block 931 are respectively welded with extension plates 933. The lower end of the lifting rod 921 is provided with a limiting groove 926 in the horizontal direction. The lower end of the lifting rod 921 is slidably penetrated in the inner cavity of the opening of the positioning block 931. The fixing column 932 is fixedly connected between the two extension plates 933. The fixing column 932 is horizontally penetrated in the limiting groove 926. The lifting rod 921 can be pulled upward until the fixing column 932 abuts against the lower end of the limiting groove 926.

[0044] Therefore, after resetting the hydraulic cylinder 81, it is necessary to position the pallet 3 to prevent the pallet 3 from swinging left and right during transportation, so as to move the lifting rod 921 downward, so that the lifting rod 921 can synchronously drive the fixed shaft 922 to slide downward in the connecting groove 924, and then the fixed shaft 922 can drive the connecting rod 923 to drive the wedge block 91 to move toward the arc-shaped protruding surface of the pallet 3. When the fixed shaft 922 moves to the lower end of the connecting groove 924, the inclined surface of the wedge block 91 presses against the arc-shaped protruding surface of the pallet 3, thereby limiting the left and right swinging of the pallet 3 during transportation.

[0045] When the transportation is completed and preparations are needed for the next transportation, the positioning of the pallet 3 must be released first. At this time, the lifting rod 921 can be pulled upward, so that the lifting rod 921 drives the fixed shaft 922 to move upward along the connecting groove 1 924. At the same time, the lifting rod 921 rotates, so that the fixed shaft 922 transitions from the connecting groove 1 924 to the connecting groove 2 925, so that the fixed shaft 922 drives the connecting rod 923 and the wedge block 91 to move in the direction away from the wheel seat 5, and then the wedge block 91 is separated from the arc-shaped protruding surface of the pallet 3, thereby releasing the positioning of the pallet 3 and allowing the pallet 3 to swing freely, which is convenient for adjustment for the next transportation.

[0046] In one embodiment, the hydraulic cylinder 81 is electrically connected to a controller, and the controller is configured as follows:

[0047] If the feedback of the pressure detection unit 71 meets the preset empty vehicle condition, such as: the pressure detection is less than 5kg, the adjustment mechanism 73 drives the counterweight block 72 to move to the preset empty vehicle balance point (such as: the center of the transport vehicle);

[0048] If the detection values ​​of the two pressure detection units 71 are different when the vehicle is empty and meet the preset terrain-induced system tilt condition (such as: a difference of 200g between the left and right sides), the multiple hydraulic cylinders 81 are ordered to perform the preset pallet balancing actions respectively until the detection values ​​of the two pressure detection units 71 are the same or meet the preset balance condition (such as: equal between the left and right sides).

[0049] The implementation principle of this embodiment is as follows: when loading on a winding and rugged inclined road section, the pallet 3 will tilt with the track 2, so the hydraulic cylinder 81 is first controlled to extend and retract to adjust the inclination angle of the load-bearing plate 4, and the cargo is loaded after the load-bearing plate 4 is in a flat state on the left and right. After the cargo is loaded, the pressure detection unit 71 detects the pressure changes on both sides of the center of the load-bearing plate 4 (that is, the loading causes the center of gravity to be wrong on the left and right), and the controller controls the motor 731 to control the counterweight block 72 to move laterally by forward and reverse rotation, so as to achieve the purpose of balancing the load-bearing plate 4. Thereafter, the hydraulic cylinder 81 is reset, and the wedge block 91 is driven to slide toward the arc-shaped raised surface close to the bottom surface of the pallet 3 by pulling the lifting rod 921. After the inclined surface of the wedge block 91 is pressed against the arc-shaped raised surface of the pallet 3, the pallet 3 is positioned, and then when transporting goods, the possibility of the load-bearing plate 4 tipping over can be reduced, thereby improving the transportation efficiency.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
