By setting up guiding and correcting components, the traditional integral guide wheel of the scraper chain guide device for the full-gantry scraper reclaimer is split into multiple independent wheel pieces. Each wheel piece can independently and adaptively adapt to the scraper chain's deviation, assembly deviation, and wear, and achieve micro-expansion compensation. This effectively avoids the problems of unilateral wear, chain biting, jamming, and force concentration that are prone to occur with integral guide wheels.

It is mainly used to limit and guide the scraper chain laterally, effectively restrain the chain from moving left and right or deviating, buffer the lateral load caused by the impact of materials, and maintain the stable and continuous operation of the whole machine in the conveying condition.
[0003] Existing technologies generally use traditional integral guide wheels, which are rigid and integral designs. Under the influence of long-term heavy-load operation, unilateral material uneven loading, and slight deformation of the large-span gantry frame of the full-gantry scraper reclaimer, the guide wheel body is prone to tilting and uneven loading and severe wear on one side.

[0018] Compared with existing technologies, the advantages of a scraper chain guide device for a full-gantry scraper reclaimer are:
[0019] 1. By setting up guiding and correcting components, the traditional integral guide wheel of the scraper chain guide device for the full-gantry scraper reclaimer is split into multiple independent wheel pieces. Each wheel piece can independently and adaptively adapt to the scraper chain's deviation, assembly deviation, and wear, and achieve micro-expansion compensation. This effectively avoids the problems of unilateral wear, chain biting, jamming, and force concentration that are prone to occur with integral guide wheels. At the same time, the multi-piece structure allows for the individual replacement of worn wheel pieces without the need for overall disassembly and assembly, greatly reducing maintenance costs and repair time.
[0020] 2. Through the set cleaning components, material dust, particulate impurities, and adhesive layers adhering to the surface of the multi-plate wheel can be automatically cleaned during the operation of the multi-plate wheel. This can prevent impurities from embedding into the gaps between the wheel plates and the contact points between the wheel plates and the scraper chain, preventing problems such as material jamming, chain edge wear, abnormal wheel wear, and abnormal noise during operation. It continuously keeps the wheel plate contact surface clean and smooth, ensuring that the multi-plate wheel extension and self-adaptive function is not interfered with by impurities, stabilizing the chain guiding accuracy and running stability, reducing the frequency of downtime due to failure, and reducing the wear rate of the wheel plates and chain plates, thus extending the overall service life of the guiding device and scraper chain.
[0021] 3. Through the set dust collection box, dust pump, dust collection pipe, horizontal pipe, telescopic hose, and adapter pipe, dust can be automatically adsorbed simultaneously during the cleaning of impurities on the wheel surface. It can collect the cleaned fine dust and suspended particles in a timely manner, preventing dust from being dispersed again and re-attached to the wheel, falling into the gap between the wheel joints, or adhering to the scraper chain surface. This maintains the clean working condition inside the guiding device, ensures the long-term stable operation of the multi-wheel adaptive guidance and telescopic compensation function, and improves the equipment's working environment, reducing dust corrosion and pollution to surrounding components.

[0040] The square opening 5 is provided with a sliding groove, and a baffle plate 37 is slidably provided in the sliding groove. The wheel axle 4 is rotatably connected to the baffle plate 37 through a sealed bearing.
[0041] Two vision sensors 38 are fixedly connected to the lower side wall of the mounting plate 39, and the vision sensors 38 are electrically connected to an external controller.
[0042] The operating principle of this invention is explained as follows: Two transmission chains inside the material handling machine are respectively fitted onto the outside of two guide components 6. Then, the operator sends an electrical signal to the external controller via an external switch. Upon receiving the signal, the controller controls the first electric push rod 102 to operate. The first electric push rod 102 pushes the piston plate inside the hydraulic tank 101 to move, transporting the hydraulic oil inside the hydraulic tank 101 to the fixed ring 12 through the hydraulic pipe 13. Subsequently, the hydraulic oil is transported to the delivery pipe 14 through the inlet hole on the surface of the transmission cover 11 and the short pipe 15. Simultaneously, the controller also controls the first control valve 18 and multiple second control valves 20 simultaneously. When opened, hydraulic oil is delivered to the first hydraulic rod assembly 62 through the infusion pipe 14, connecting pipe 17 and multiple connecting pipes 19 (the hydraulic rod assembly includes a hydraulic cylinder and a hydraulic seat; by delivering hydraulic oil into the hydraulic cylinder, the lifting and lowering of the hydraulic seat can be controlled), causing the first hydraulic rod assembly 62 to drive the wheel 8 to move outward. The wheel 8 tensions the transmission chain. When the controller detects that the pressure on the axle 4 reaches the set threshold (11kN) through the pressure sensor (not shown in the figure) between the connecting frame 2 and the connecting ring 3, the controller will control the first electric push rod 102 to stop working and control the first control valve 18 and the second control valve 20 to close.
[0043] When the guide device experiences chain misalignment during subsequent operation, the misaligned chain will press against one side of the wheel 8, causing the wheel 8 to tilt. After the controller detects this situation through the two ranging probes 40 on the surface of the moving plate 7, it will repeat the above principle, supplying hydraulic oil to the infusion pipe 14 and controlling the corresponding third control valve 23 and fourth control valve 24 to open, so that the hydraulic oil is supplied to the second hydraulic cylinder assembly. The second hydraulic cylinder assembly drives the straightening plate 26 to move outward. The straightening plate 26 will push the misaligned side of the wheel 8 to correct it until the wheel 8 is kept in its initial straight state. Then the controller will control the first electric push rod 102 to stop working and control the third control valve 23 and fourth control valve 24 to close.
[0044] When the controller detects impurities adhering to the surface of the wheel piece 8 via the vision sensor 38, it controls the corresponding second electric push rod 271 to operate. The second electric push rod 271, through the moving frame 272, moves the perforated cylinder 29 and the dust removal plate 30 towards the wheel piece 8 at a set distance, so that the dust removal plate 30 contacts the wheel piece 8. When the wheel piece 8 rotates under the drive of the chain, because the dust removal plate 30, the perforated cylinder 29, and the rotating tube 28 are connected by the resistance bearing and the moving frame 272, friction and relative displacement will occur between the wheel piece 8 and the dust removal plate 30. The dust removal plate 30 can clean the impurities off the surface of the wheel piece 8. The controller controls the operation of the vacuum pump 32, which extracts the gas from the vacuum box 31, putting the vacuum box 31 under negative pressure (the vacuum box 31 is equipped with a filter element located at the air inlet of the vacuum pump 32). Dust and particles cleaned from the surface of the wheel 8 are transported to the vacuum box 31 under negative pressure through the multi-hole cylinder 29, the rotating pipe 28, the connecting pipe 36, the telescopic hose 35, the horizontal pipe 34, and the suction pipe 33. The controller also controls the opening of one solenoid valve (not shown in the figure) and the closing of the other solenoid valve inside the horizontal pipe 34 to ensure that the negative pressure inside the corresponding multi-hole cylinder 29 is of appropriate strength.
[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
