Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can be arranged and designed in various different configurations. Specific model specifications need to be selected and determined according to the actual specifications of the device, etc. The specific selection calculation method adopts existing technology in the art, and therefore will not be described in detail.

[0027] Example

[0028] like Figures 1-8 As shown, this utility model provides a ball mill liner installation vehicle, including a mobile platform. The mobile platform includes a chassis 1. Two travel motors 2 are installed at the lower front end of the chassis 1 through a chassis connector 4. The travel motors 2 are connected to the drive wheels of the track 3. When the two travel motors 2 rotate in the same direction, the installation vehicle travels in a straight line. When the two travel motors 2 rotate in opposite directions, the installation vehicle turns in place or makes a slight angle adjustment. A control device, a liner picking device, and a liner conveying device are provided on the upper surface of the chassis 1. The control device is used to control the operation of the installation vehicle. Lifting unloading devices are provided on the left and right sides of the front end of the chassis 1. A support device is provided below the lifting unloading devices.

[0029] The liner picking device includes a hydraulic cylinder 6, which is located on the upper front surface of the chassis 1 and connected to the bottom of the liner box 5 via a limiting pin 8. The liner box 5 is centrally located above the chassis 1. A 50mm wide axial through groove is provided in the middle of the bottom surface of the liner box 5 to facilitate the liner conveying device to convey the liner. A clamping screw 7 is located in front of the liner box 5. The two sliders of the clamping screw 7 are bolted to the front of the liner box 5. The hydraulic cylinder 6 and the clamping screw 7 drive the liner box 5 to pick up the liner, so that the liner box 5 has the dual functions of a storage compartment and a liner picking device robot.

[0030] The clamping screw 7 has threads with different directions of rotation but the same specifications at both ends. Driving the clamping screw 7 to rotate causes the liner box 5 to open to its maximum width. Then, the hydraulic cylinder 6 injects pressurized oil to lift the front of the unloaded liner box 5, and the rear of the liner box 5 moves along the arc-shaped track at the rear of the chassis 1 until the thin-walled surface of the rear of the liner box 5 aligns with the ground. As the clamping screw 7 slowly retracts, the blade-like thin-walled surface of the liner box 5 inserts into the gap between the ground and the liner plates, ultimately clamping the sides of multiple liner plates firmly. After clamping, the hydraulic cylinder 6 reverses its action, slowly pulling the fully loaded liner box 5 back along the track of the chassis 1 until the bottom surface of the liner box 5 precisely aligns with the chassis 1. Figure 1As shown; the height of the liner box 5 is 450mm, and the thickness of the liner is generally 50mm-130mm. It can pick up 3-10 liners at a time, which is significantly more efficient than the traditional manual installation of one liner at a time.

[0031] The liner conveying device includes a conveying motor 9, which is symmetrically located at the rear end of the chassis 1 with respect to the synchronous belt pulley 10. The conveying motor 9 is connected to the small gear 11 of the reducer. The small gear 11 and the large gear 12 of the reducer mesh with each other and are adjacent to each other. The large gear 12 of the reducer is coaxial with the synchronous belt pulley 10. After the conveying motor 9 is powered on, the synchronous belt conveys the liner one by one to the liner lifting handle 16. The structure is simple and the failure rate is low.

[0032] The lifting unloading device includes a lifting screw 13, which is symmetrically arranged on both sides of the front end of the chassis 1 via four first guide rails 18. Each first guide rail 18 is fitted with a return spring 19. One end of the return spring 19 is fixedly connected to the chassis 1, and the other end abuts against the protrusion of the first guide rail 18. A rotatable baffle 17 is provided on the inner side of the top of the lifting screw 13. The baffle 17 is connected to the pin at the upper end of the lifting screw 13 to realize the function of the baffle 17 rotating around the pin. The drive motor 15 is connected to the lifting screw 13. The slider of the lifting screw 13 is connected to the liner lifting handle 16 through the first connector 14.

[0033] When the liner is delivered to the liner lifting handle 16, the drive motor 15 starts and drives the lifting screw 13 to rotate, so that the first connecting piece 14 connected to the slider of the lifting screw 13 moves down synchronously. Since the first connecting piece 14 is rigidly connected to the liner lifting handle 16, the lifting handle will descend to the preset lowest position along with the slider, and remain in standby state until the next installation process is entered.

[0034] During the liner pickup process, the hydraulic cylinder 6 retracts, slowly pressing down the liner box 5. If the width of the liner to be picked up is greater than the width of the chassis 1, the liner will interfere with the lifting screw 13. Therefore, the distance between the two lifting screws 13 is required to change with the width of the liner to be picked up.

[0035] When the fully loaded liner box 5 is pressed down to the top of the lifting screw 13, the inner side of the baffle 17 contacts the outer side of the liner box 5 and generates a horizontal component force, forcing the lifting screws 13 on both sides to slide outward along the first guide rail 18. Finally, the baffle 17 remains vertical, and the return spring 19 is compressed, realizing the function of width adjustment. At this time, the inner side of the baffle 17 is close to the outer side of the liner box 5 and close to the lifting screw 13, so that the lifting screw 13 also remains vertical, ensuring the installation accuracy of the liner. When the liner box 5 is raised again, the elastic restoring force of the return spring 19 pushes the protrusion of the first guide rail 18, thereby pulling the side of the lifting screw 13 to automatically return to its original position, realizing the adaptive adjustment of the spacing.

[0036] The support device includes a support motor 20, which is connected to a bevel gear reducer 21 via a motor bracket on the chassis 1. This changes the power transmission direction of the drive motor 15 and increases the torque at the output end of the bevel gear reducer 21, allowing the lead screw 24 to rotate. The inner hole of the output end of the bevel gear reducer 21 is threaded and connected to the upper end of the lead screw 24. The inner hole of the support member 23 is threaded and connected to the lower end of the lead screw 24. One end of the second guide rail 22 is connected to the bevel gear reducer 21, and the other end is connected to the support member 23, so that the support member 23 can only rotate with the lead screw 24 and move linearly along the second guide rail 22.

[0037] When the installation vehicle picks up the liner, the full weight of the liner box 5 may cause the installation vehicle to become unbalanced. At this time, the lead screw 24 drives the support 23 to move down to the ground, providing external support for the installation vehicle and effectively preventing it from tipping over.

[0038] When the liner is installed, as the liner support 16 lowers to its lowest position carrying the liner, there is still a gap of approximately 15cm between the liner support 16 and the ground. At this point, the lead screw 24 rotates, causing the support member 23 to move upward. After the support member 23 moves upward and comes into contact with the liner support 16, it continues to move upward, pushing one end of the liner support 16 to rise (e.g., Figure 8 (As shown), thus achieving a smooth tilting of the liner; the installation vehicle then slowly reverses, thereby precisely tilting the liner to the installation position;

[0039] A servo motor 25 is installed on the upper part of the liner box 5. The servo motor 25 is connected to the depth camera 26 via a linkage to provide multi-directional video information for the installation vehicle control device. When the servo motor 25 is powered on, the depth camera 26 can provide image information to the installation vehicle, including: identifying the relative position of the installation vehicle and the liner to be picked up, thereby completing the picking function; determining the accurate position of the liner in the ball mill, thereby realizing the liner installation function; detecting the surrounding working environment and performing work.

[0040] Therefore, this utility model adopts a ball mill liner installation vehicle, which can adapt to the installation of liners of various sizes, has high installation efficiency, and improves the safety of the installation process by transforming manual operation into mechanized operation.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
