Description

Technical Field

[0001] The invention relates to the technical field of scraper production, and in particular to a quenching and feeding device and method for a heavy-duty scraper axe head of a mining conveyor. Background Art

[0002] Scrapers are used in heavy machinery and equipment manufacturing enterprises, and the quenching process before use is indispensable. During the quenching process, the scrapers need to be frequently moved. Currently, manual quenching is used, that is, the operator moves the scraper to the quenching furnace and places it on the quenching furnace for quenching. The scraper is a large and heavy component. Using the above method will undoubtedly cause the problem of high labor intensity for the operator.

[0003] With the advancement of intelligent technology, robots are being used for grasping and machine vision for imaging and positioning. Robotic grasping and loading offers advantages such as high freedom of movement and precision. However, these systems have drawbacks such as increased price with higher payloads, high capital investment in equipment, and increased manufacturing costs per part. Gantry-type grasping and loading systems also have limitations in terms of weight capacity and high costs. Gantry-type robots also impact the use of overhead cranes in workshops, limiting the use of large scraper hoisting operations and increasing auxiliary time in the quenching process.

DETAILED DESCRIPTION

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0040] In the description of the present invention, it should be understood that the terms "upper", "middle", "outer", "inner", "lower" and the like indicating directions or positional relationships are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific direction, be constructed and operate in a specific direction, and therefore should not be understood as limiting the present invention.

[0041] Please see Figures 1 to 7In one embodiment, the present invention provides a heavy-duty scraper axe quenching and loading device for a mining conveyor, comprising a support plate 01, a rotating support mechanism 02, and a lifting and transporting mechanism 03; guide rails 04 are symmetrically arranged on both sides of the support plate 01; the layout direction of the guide rails 04 is parallel to the moving guide rails of the scraper quenching machine 07. The rotating support mechanism 02 is arranged on the top of the support plate 01, and the rotating support mechanism 02 can rotate circumferentially to adjust the angle of the scraper placed on the rotating support mechanism 02; under normal circumstances, it is only necessary to rotate the scraper 90°. The lifting and transporting mechanism 03 includes a left lifting and transporting assembly 31 and a right lifting and transporting assembly 32; the left lifting and transporting assembly 31 and the right lifting and transporting assembly 32 can respectively move back and forth along the guide rails 04 on both sides of the support plate 01 to lift and transport the scraper placed on the tray 213 to the quenching device. The left lifting and transporting assembly 31 and the right lifting and transporting assembly 32 are used to realize the linear lifting and loading of the scraper, which is not only suitable for the loading and unloading of scrapers of different lengths, but also enables the scraper to be centered and aligned when loading, reducing the centering and alignment operations of personnel and improving the quenching efficiency; due to the adoption of the stacking feeding method, when loading the scraper, it is only necessary to rotate the scraper stack 06 90° to achieve the adjustment of the scraper angle, so that the left lifting and transporting assembly 31 and the right lifting and transporting assembly 32 can lift the scraper for loading, which can not only ensure a certain feeding amount, but also shorten the loading distance. Based on the cost priority and the efficiency is not reduced, choosing this device can achieve the best economy.

[0042] In one embodiment, the rotating support mechanism 02 includes a rotating component 21 and a power component 22; the rotating component 21 is arranged on the top of the support plate 01, and the power component 22 is arranged on one side of the rotating component 21. The power component 22 is connected to the rotating component 21 so that the power component 22 can drive the rotating component 21 to rotate circumferentially to adjust the angle of the scraper placed on the rotating component 21.

[0043] Among them, the rotating component 21 includes a thrust bearing 211, a gear disc 212, and a tray 213; the thrust bearing 211 is arranged on the top of the support plate 01, the gear disc 212 is fixed on the top of the thrust bearing 211, and the tray 213 is installed on the top of the gear disc 212. The tray 213 can rotate synchronously with the gear disc 212.

[0044] The power assembly 22 includes a telescopic portion 221 and a rack 222. The telescopic portion 221 is located on top of the support plate 01 and on one side of the toothed disc 212. The rack 222 is fixed to the end of the telescopic portion 221 and meshes with the toothed disc 212. When the telescopic portion 221 is pushed or pulled, the rack 222 drives the toothed disc 212 to rotate. The telescopic portion 221 is powered by a hydraulic cylinder.

[0045] A guide column 23 is provided on the top of the support plate 01 to provide guidance for the rack 222 .

[0046] In one embodiment, a lifting mechanism 05 capable of adjusting the height of the support plate 01 is provided below the support plate 01. The lifting mechanism 05 is a hydraulic cylinder.

[0048] Specifically, an L-shaped stop plate 314 is installed on the lifting plate 313. A pressure sensor 315 is mounted on this stop plate 314. When the scraper blade contacts the pressure sensor 315, it can detect whether the scraper blade is placed parallel to the lifting plate 313. A pusher 316 is installed on the stop plate 314. This pusher 316 extends toward the center and can clamp the scraper blade to ensure centering, reducing the need for centering and alignment, thereby improving quenching efficiency. The pusher 316 is a hydraulic cylinder.

[0050] S1: Palletize the scrapers in an alternating stack, placing them in the center of the pallet 213;

[0051] S2: After the scraper palletizing is completed, the lifting frame 311 is controlled to move toward the pallet 213, and stops moving when the pressure sensor 315 on the limit plate 314 contacts the scraper and the pressure reaches the set value. The lifting frame 311 can only completely stop moving after the pressure sensors 315 on the limit plates 314 on both sides of the lifting frame 311 have reached the set pressure value.

[0052] S3: Control the lifting part 312 to rise upward, so that the tray 213 begins to lift up, and the lifting part 312 stops after reaching the set value;

[0053] S4: Control the pushing portion 316 to extend, and push the two ends of the scraper toward the middle, so that the scraper is centered on the quenching machine;

[0055] S6: Control the lifting part 312 to retract, so that the lifting plate 313 moves downward, and the scraper is lowered to the moving guide plane of the scraper quenching machine 07. After the scraper is placed on the guide plane, the lifting plate 313 continues to move downward and stops below the lower plane of the scraper;

[0056] S7: Continue to execute steps 2-6 until all the scrapers on the same layer are loaded, and move the lifting frame 311 to the initial position;

[0057] S8: Control the lifting mechanism 05 to rise, lift the support plate 01 upward, and stop when it reaches the set height;

[0058] S9: Control the telescopic part 221 to rotate the support plate 01 90° and stop when it reaches the right position;

[0059] S10: Continue to execute steps 2-6 until the scraper is loaded.
