Description

Technical Field

[0001] This utility model relates to the technical field of hook-off positioning structure, specifically a hook-off positioning structure for a tipper. Background Technology

[0002] A tipper is a mechanical device specifically designed for the efficient and safe tipping of heavy transport vehicles (such as train carriages and trucks) to achieve rapid unloading of goods. It is widely used in logistics and industrial fields such as ports, railway freight stations, steel plants, mines, and power plants. Through its mechanical structure, it flips transport vehicles (such as open wagons and mining cars) to a certain angle (usually 160°-180°), allowing the goods inside (such as bulk materials such as coal, ore, and grain) to be automatically unloaded by gravity.

[0003] Existing tippler hook-off positioning structures use visual cameras for positioning. However, these cameras are fixed with multiple bolts, which requires a lot of time to disassemble and replace, making the operation complex and cumbersome. To address this issue, a tippler hook-off positioning structure is provided. Summary of the Invention

[0004] The purpose of this utility model is to provide a hook-unhooking and positioning structure for a tipper, thereby solving the problems mentioned in the background art. To achieve the above objective, this utility model provides the following technical solution: a hook-unhooking and positioning structure for a tipper, including a slide rail, a slide plate slidably sleeved on the outside of the slide rail, a robotic arm disposed at the top of the slide plate, a fixed plate disposed at the output end of the robotic arm, a clamp disposed on the fixed plate, a frame disposed at the front end of the fixed plate, a sliding assembly disposed in the inner cavity of the frame, two moving rods disposed at the top of the sliding assembly, a clamping plate disposed on each of the two moving rods, and a camera clamped and fixed between the two clamping plates.

[0005] Preferably, the sliding assembly includes a lead screw, a knob, sliders, and a limiting assembly. One end of the lead screw is rotatably connected to the left side of the inner cavity of the frame via a bearing, and the other end of the lead screw extends to the right end of the frame and is fixedly connected to the knob. The two sliders are respectively screwed to the left and right sides of the outer wall of the lead screw and are respectively fixedly connected to the two moving rods. The limiting assembly is located at the front end of the fixed plate and is fixedly connected to the two sliders.

[0006] Preferably, the threads on the left and right sides of the outer wall of the lead screw are arranged opposite to each other.

[0007] Preferably, the limiting component includes a limiting groove and limiting blocks. The limiting groove is opened at the front end of the fixed plate. The two limiting blocks are slidably embedded in the inner cavity of the limiting groove and are respectively fixedly connected to two sliders. The inner cavity of the limiting groove and the outer wall of the limiting block are adapted to each other and are both in the shape of a "T".

[0008] Preferably, a gear is fixedly sleeved on the right end of the lead screw, an mounting plate is provided at the front end of the fixing plate, a screw is screwed onto the mounting plate, a rack is rotatably connected to the top end of the screw via a bearing, the rack meshes with the gear, a handle is provided at the bottom end of the screw, and a connecting component is provided at the front end of the fixing plate, the connecting component is fixedly connected to the rack.

[0009] Preferably, the connecting component includes a connecting groove and a connecting block. The connecting groove is formed at the front end of the fixing plate, and the connecting block is slidably embedded in the inner cavity of the connecting groove and fixedly connected to the rack.

[0010] Preferably, the inner cavity of the connecting groove and the outer wall of the connecting block are adapted to each other and are both dovetail-shaped.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: Rotating the knob causes the lead screw to rotate, which in turn generates a relative thread rotation force on the opposite threads on the left and right sides of the lead screw's outer wall. This causes the two sliders to slide simultaneously toward the center of the lead screw under the limiting action of the limiting groove and the limiting block. This causes the two moving rods to drive the two clamping plates to slide simultaneously toward the top center of the fixed plate, clamping and fixing the camera. This facilitates the installation and removal of the camera, solving the problem that the existing tipper hook-unhooking positioning structure uses a visual camera for positioning, but the existing visual camera is fixed with multiple bolts, which requires a lot of time to disassemble and replace during installation and removal, making the operation complicated and troublesome. After the camera is clamped in the clamping plate, rotate the handle to make the screw rotate. Since the screw is screwed to the mounting plate, when the screw rotates, the rack can slide upward in a straight line and mesh with the gear under the limiting action of the connecting groove and the connecting block. This can achieve the positioning of the lead screw and prevent the lead screw from rotating due to factors such as vibration, which could cause the camera to fall out of the clamping plate. This improves the stability of the device during use. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1 to 4 This utility model provides a technical solution: a tipper hook-unhooking and positioning structure, including a slide rail 1, a slide plate 2 slidably sleeved on the outside of the slide rail 1, a mechanical arm 3 set at the top of the slide plate 2, a fixed plate 4 set at the output end of the mechanical arm 3, a clamp 5 set on the fixed plate 4, a frame 6 set at the front end of the fixed plate 4, a sliding component set in the inner cavity of the frame 6, two moving rods 7 set at the top of the sliding component, each of the two moving rods 7 set with a clamping plate 8, and a camera 9 clamped and fixed between the two clamping plates 8. Through the setting of the sliding component, the two moving rods 7 can drive the two clamping plates 8 to slide simultaneously towards the top center of the fixed plate 4 to clamp and fix the camera 9, thereby facilitating the installation and removal of the camera 9. This solves the problem that the existing tipper hook-unhooking and positioning structure uses a visual camera 9 for positioning, but the existing visual camera 9 is fixed with multiple bolts, which requires a lot of time to install and remove the bolts during installation and removal, making the operation complicated and troublesome.

[0016] In this embodiment, the sliding assembly includes a lead screw 10, a knob 14, sliders 11, and a limiting assembly. One end of the lead screw 10 is rotatably connected to the left side of the inner cavity of the frame 6 via a bearing, and the other end of the lead screw 10 extends to the right end of the frame 6 and is fixedly connected to the knob 14. Two sliders 11 are respectively screwed to the left and right sides of the outer wall of the lead screw 10 and are respectively fixedly connected to two moving rods 7. The limiting assembly is located at the front end of the fixed plate 4 and is fixedly connected to the two sliders 11. The knob 14 drives the lead screw 10 to rotate, thereby generating a relative thread rotation force on the opposite threads on the left and right sides of the outer wall of the lead screw 10. Under the limiting action of the limiting groove 12 and the limiting block 13, the two sliders 11 slide simultaneously toward the middle of the lead screw 10, and the two moving rods 7 respectively drive the two clamping plates 8 to slide simultaneously toward the top center of the fixed plate 4 to clamp and fix the camera 9.

[0017] In this embodiment, the threads on the left and right sides of the outer wall of the lead screw 10 are arranged opposite to each other, so that when the lead screw 10 rotates, the left and right sides of its outer wall generate relative thread rotation force, so that the two sliders 11 slide relative to each other simultaneously under the limiting action of the limiting groove 12 and the limiting block 13.

[0018] In this embodiment, the limiting component includes a limiting groove 12 and limiting blocks 13. The limiting groove 12 is opened at the front end of the fixing plate 4. Both limiting blocks 13 are slidably embedded in the inner cavity of the limiting groove 12 and are respectively fixedly connected to two sliders 11. Under the joint action of the limiting groove 12 and the limiting blocks 13, the sliders 11 can be prevented from rotating with the lead screw 10 when the lead screw 10 rotates, which improves the stability of the sliding component during use. The inner cavity of the limiting groove 12 and the outer wall of the limiting block 13 are adapted to each other and are both in the shape of "T", which can keep one end of the limiting block 13 embedded in the inner cavity of the limiting groove 12, which improves the stability of the limiting component during use.

[0019] In this embodiment, a gear 15 is fixedly sleeved on the right end of the lead screw 10, and a mounting plate 16 is provided at the front end of the fixing plate 4. A screw 19 is screwed onto the mounting plate 16, and a rack 20 is rotatably connected to the top end of the screw 19 through a bearing. The rack 20 meshes with the gear 15, and a handle 21 is provided at the bottom end of the screw 19. A connecting component is provided at the front end of the fixing plate 4, and the connecting component is fixedly connected to the rack 20. Rotating the handle 21 causes the screw 19 to rotate. Since the screw 19 is screwed onto the mounting plate 16, when the screw 19 rotates, the rack 20 can slide upwards along a straight line and mesh with the gear 15 under the limiting action of the connecting groove 17 and the connecting block 18. This can achieve the positioning of the lead screw 10, prevent the lead screw 10 from rotating due to factors such as vibration, and prevent the camera 9 from being dislodged from the clamping plate 8. This improves the stability of the device during use.

[0020] In this embodiment, the connecting component includes a connecting groove 17 and a connecting block 18. The connecting groove 17 is opened at the front end of the fixing plate 4. The connecting block 18 is slidably embedded in the inner cavity of the connecting groove 17 and fixedly connected to the rack 20. Under the joint action of the connecting block 18 and the connecting groove 17, the rack 20 can always slide along a straight line, ensuring that the rack 20 can mesh with the gear 15.

[0021] In this embodiment, the inner cavity of the connecting groove 17 and the outer wall of the connecting block 18 are adapted to each other and are both dovetail-shaped, which can keep one end of the connecting block 18 embedded in the inner cavity of the connecting groove 17, thus improving the stability of the connecting assembly during use.
