It should be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0036] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0037] Example 1

[0038] Please refer to Figure 1-2 As shown, an embodiment of this utility model provides a rapid loading device for multi-size quartz tubes, including: a housing 1, a lifting assembly 2, a translation assembly 3, a rolling support assembly 5, a storage battery 6, and an electrical control box.

[0039] Box 1, serving as the load-bearing foundation of the entire device, is welded from high-strength alloy materials, possessing excellent structural stability and load-bearing capacity. Its interior forms a space for installing various functional components, and its external surface undergoes anti-corrosion treatment to adapt to industrial environments.

[0040] The lifting assembly 2 is located inside the housing 1 and extends through the top of the housing 1. This assembly adopts a precision transmission structure, which can realize the smooth lifting of the quartz tube in the vertical direction. Through precise control, quartz tubes of different specifications can be accurately moved to a position flush with the inlet of the annealing furnace. The lifting stroke can be adjusted according to actual needs to meet the usage requirements of annealing furnaces of different heights.

[0041] The translation component 3 is located on top of the lifting component 2 and forms a stable connection with the lifting component 2. It is equipped with a high-precision guiding mechanism and positioning device, which can flexibly adjust the position of the quartz tube in the horizontal direction. The adjustment process is smooth and without shaking, ensuring that the quartz tube can be accurately aligned with the annealing furnace inlet, eliminating loading difficulties caused by position deviation.

[0042] The rolling support assembly 5 is fixedly installed at the top of the translation assembly 3 near the annealing furnace. This assembly includes multiple sets of rotatable support structures, which can form a stable rolling support for one end of the quartz tube. During the transportation of the quartz tube, it can effectively reduce frictional resistance and avoid scratching the surface of the quartz tube. At the same time, its support angle and spacing can be adaptively adjusted according to the diameter of the quartz tube to meet the support requirements of quartz tubes of different sizes.

[0043] The conveying component 4 is located at the top of the translation component 3, away from the annealing furnace, and smoothly and uniformly conveys the quartz tube placed on it into the annealing furnace.

[0044] The storage battery 6 is fixedly installed inside the housing 1. It is a high-capacity, long-life industrial-grade storage battery 6, which can provide a stable power supply for all electrical components of the entire device. It is equipped with an intelligent charging management system, which can realize fast charging and overcurrent protection, ensuring that the device can work normally without an external power source, and improving the mobility of the device.

[0045] The electrical control box is electrically connected to the battery 6 and the lifting assembly 2 respectively. It has a built-in microprocessor and control circuit, which can precisely control the lifting action of the lifting assembly 2. It also integrates the operation panel and status indicator lights. The operator can set relevant parameters through the operation panel, and the status indicator lights can display the operating status of the device in real time, which is convenient for the operator to monitor and operate. In addition, the electrical control box also has overload protection, fault alarm and other functions to improve the safety of the device.

[0046] Each of the four corners of the bottom of the housing 1 is equipped with casters 7, including two directional casters and two omnidirectional casters, with brakes on the omnidirectional casters. The omnidirectional casters allow the device to move flexibly in the horizontal direction, making it easy for operators to change the direction of movement in workshops and other locations, without being limited by space or angle. The brakes lock the omnidirectional casters when the device reaches the designated position, preventing accidental slippage during operations such as loading quartz tubes, ensuring the device maintains a stable position during operation, and further improving the convenience and safety of the device.

[0047] Example 2

[0048] like Figure 2 , Figure 7As shown, the lifting assembly 2 includes a rack and pinion motor 21 located inside the housing 1 and fixedly connected to its top wall by high-strength bolts 56. The rack and pinion motor 21 adopts a high-precision gear transmission mechanism, which has the characteristics of large output torque, smooth operation and low noise. Its rated speed can be adjusted according to the actual lifting requirements to ensure controllability during the lifting process.

[0049] The rack on the rack and pinion motor 21 passes vertically upward through a pre-set hole in the top wall of the housing 1, and both ends of the rack are fixedly connected to horizontally arranged crossbeams 22 by bushings and screws. The crossbeams 22 are made of thick-walled square steel and have extremely strong load-bearing capacity, which can effectively distribute the load borne by the rack. Each end of the crossbeams 22 is fixedly connected to lifting plates 23 perpendicular to each other by welding. The lifting plates 23 are rectangular steel plates with polished surfaces to ensure the flatness of the connecting plane.

[0050] Two parallel guide shafts 24, which pass through guide holes in the top wall of the housing 1, are fixed between the two vertically positioned lifting plates 23 by bushings and screws. The first guide shafts 24 are made of high-hardness alloy steel and are chrome-plated to reduce the coefficient of friction. They are clearance-fitted with the guide holes in the top wall of the housing 1 and can play a precise guiding role when the rack drives the crossbeam 22 and the lifting plates 23 to rise and fall, effectively preventing deviation or shaking during the lifting process and ensuring the stability and reliability of the entire lifting assembly 2.

[0051] Example 3

[0052] like Figure 2-4 As shown, the translation component 3 is located outside the box 1 and is in the middle of the entire device. It mainly includes a horizontally set support plate 31 and two parallel first slide rails 32. The support plate 31 is made of high-strength alloy plate and the surface is finely ground to ensure flatness. It can stably support the weight of the conveying component 4, the rolling support component 5 and the quartz tube installed above.

[0053] The two first slide rails 32 correspond one-to-one with the two lifting plates 23 on the top of the lifting assembly 2, and are fixedly connected to the upper surface of the lifting plate 23 by countersunk bolts 56. The first slide rails 32 are made of wear-resistant steel, and their length direction is perpendicular to the annealing furnace inlet direction, so as to provide sufficient stroke space for horizontal adjustment.

[0054] Each of the first slide rails 32 is slidably connected to two high-precision first sliders 33. The first sliders 33 are inlaid with wear-resistant balls to ensure smooth sliding without jamming. The fit gap between the first sliders 33 and the first slide rails 32 is precisely controlled to ensure the straightness of the sliding.

[0055] One of the first sliders 33 has a through threaded hole on its side wall along a direction perpendicular to the length of the first slide rail 32. A locking handle 34 with a rubber anti-slip pad is threaded into the threaded hole. When the translation position is adjusted to the correct position, the end of the locking handle 34 is pressed tightly against the side wall of the first slide rail 32 when the locking handle 34 is rotated, which can fix the first slider 33 and the first slide rail 32 relative to each other and prevent displacement during operation.

[0056] The tops of the four first sliders 33 are fixed with the support plates 31 by screws, thereby forming a stable four-point support structure. This ensures that the support plates 31 remain horizontal during translation adjustment, avoiding tilting or deformation caused by uneven force, and thus ensuring the stability and positional accuracy of the quartz tube during horizontal movement.

[0057] Example 4

[0058] like Figure 2-4 As shown, the conveying component 4 serves as the core power mechanism for the quartz tube to enter the annealing furnace. It includes a second slide rail 41 that is fixed to the upper surface of the support plate 31 by screws and extends along the length of the support plate 31. The second slide rail 41 adopts a high-precision linear guide structure and is made of high-strength alloy steel. The surface is hardened to improve wear resistance and ensure that it can maintain good guiding accuracy after long-term use.

[0059] A matching second slider 42 is slidably connected to the second slide rail 41. The second slider 42 is embedded with balls, which can achieve low friction and high stability sliding. A small drive motor 43 is fixed on the top of the second slider 42 by positioning pins and screws. The drive motor 43 adopts servo drive technology and has the characteristics of adjustable speed and fast start and stop response, which can accurately control the speed.

[0060] A worm gear is fixedly mounted on the output shaft of the drive motor 43 and meshes with the turbine. The turbine is rotatably connected to the top wall of a protective cover via a bearing seat. The drive motor 43, the worm gear, and the turbine are all located inside the protective cover. A lead screw 44 is threaded onto the turbine and passes through a pre-drilled hole at the top of the protective cover. A support plate 45 for supporting the quartz tube is fixedly mounted at the top of the lead screw 44. A high-temperature resistant silicone pad is attached to the surface of the support plate 45 that contacts the quartz tube, which can stably support the quartz tube and avoid damage to the surface of the quartz tube from hard contact.

[0061] Two second guide shafts 46, which are fixedly connected to the support plate 31, are arranged parallel to each other on one side of the second slide rail 41. The shafts of the two second guide shafts 46 are chrome-plated to reduce the coefficient of friction. A rectangular moving plate 47 is slidably connected to them. The moving plate 47 has a groove 48 in the middle of the side of the second slide rail 41 that slides with the support plate 45 in the vertical direction. The width of the groove 48 is slightly larger than the thickness of the support plate 45. It plays an auxiliary guiding and anti-tilting role during the transport of quartz tubes.

[0062] The movable plate 47 has two circular through holes 49 for the second guide shaft 46 to pass through. A linear bearing 410 with a locking device is fixedly installed in either of the through holes 49 by interference fit. This bearing can not only reduce the resistance of the movable plate 47 sliding along the second guide shaft 46, but also fix the movable plate 47 at any position on the second guide shaft 46 during the conveying process.

[0063] A photoelectric sensor 411 is fixedly installed on the side of the movable plate 47 near the rolling support assembly 5. The photoelectric sensor 411 and the drive motor 43 are both electrically connected to the electrical control box. Specifically, the photoelectric sensor 411 converts the light signal obtained by identifying the height difference between the pallet 45 and the rolling support assembly 5 into an electrical signal. The electrical signal is transmitted to the electrical control box, which then controls the drive motor 43 to drive the lead screw 44 to rotate, thereby causing the pallet 45 to move upward until the center of the quartz tube placed on the pallet 45 and the rolling support assembly 5 reaches the same horizontal line as the annealing furnace inlet. The pallet 45 will then stop moving upward.

[0064] Example 5

[0065] like Figure 3-6 As shown, the rolling support assembly 5, as a key support structure in the quartz tube conveying process, includes two sets of support rollers 54 symmetrically arranged along the width direction of the support plate 31, and the two sets of support rollers 54 are distributed in an inverted "V" shape. This layout can form a "clamping" support through the rollers on both sides. Even if there are slight differences in the diameter of the quartz tube, it can achieve stable support through the adaptive contact of the rollers. At the same time, the inverted "V" structure can guide the quartz tube to automatically align during the conveying process, further improving the alignment accuracy.

[0066] Each set of support rollers 54 includes two cylindrical rollers of the same size. The rollers are made of wear-resistant ceramic material and the surface is polished to reduce the coefficient of friction with the quartz tube and prevent scratching the outer wall of the quartz tube during transport. Both support rollers 54 are rotatably mounted on wheel seats 53 via stainless steel shafts. Miniature deep groove ball bearings are installed at the connection between the shaft and the wheel seat 53 to ensure that the support rollers 54 rotate flexibly and without jamming, thereby reducing the resistance during the transport of the quartz tube.

[0067] The wheel seat 53 is an "L"-shaped metal component. The bottom of the wheel seat 53 is hinged to the top of the bracket 52 by a pin and can rotate around the pin at a certain angle. The bracket 52 is made of solid square steel and has a high load-bearing capacity. The bottom of the bracket 52 is fixed to the base plate 51 by welding.

[0068] The base plate 51 is a rectangular square steel plate, which is fixed to the upper surface of the support plate 31 by screws. The installation position of the base plate 51 is located at the end of the second slide rail 41 near the annealing furnace and extends along the width direction of the support plate 31. This installation position can ensure that the support roller 54 and the pallet 45 of the conveying assembly 4 form a continuous support path. At the same time, the width of the base plate 51 is slightly larger than the distribution width of the two sets of support rollers 54, which provides sufficient space for subsequent adjustment of the angle of the support rollers 54.

[0069] To accommodate quartz tubes of different diameters, the top of the bracket 52 is provided with an arc-shaped groove 55, and the inner wall of the groove 55 is polished to reduce friction. The wheel seat 53 is provided with a threaded hole corresponding to the groove 55, and a bolt 56 with an anti-slip knob is threaded into the threaded hole. When the bolt 56 is rotated, the wheel seat 53 rotates around the hinge of the bracket 52.

[0070] When adjusting the angle of the support rollers 54, the operator simply needs to turn the anti-slip knob on the bolt 56: if the bolt 56 rotates clockwise, its end will push into the groove 55, forcing the wheel seat 53 to rotate outward around the hinge, thereby reducing the opening width between the two sets of support rollers 54 to accommodate quartz tubes with larger diameters; if the bolt 56 rotates counterclockwise, its end will retract from the groove 55, and the wheel seat 53 will rotate inward under the weight of the quartz tube or with manual assistance, increasing the opening width between the two sets of support rollers 54 to accommodate quartz tubes with smaller diameters. The entire adjustment process requires no disassembly of parts, is convenient to operate, and has high angle adjustment accuracy, meeting the support needs of various specifications of quartz tubes.

[0071] The working process of the rapid loading device:

[0072] In use, first place one end of the quartz tube on the support plate 45 and the other end on the support roller 54. Then, control the rack and pinion motor 21 via the control box. The rack and pinion motor 21 drives the rack to move up and down, which in turn drives the translation assembly 3, the conveying assembly 4, the rolling support assembly 5, and the quartz tube to move vertically until the quartz tube is flush with the annealing furnace inlet. Next, push the support plate 31 to make the first slider 33 slide on the first slide rail 32, adjusting the horizontal position of the quartz tube so that it is aligned with the annealing furnace inlet. After adjustment, tighten the locking handle 34 to fix it. Then, convey the quartz tube into the annealing furnace, while the moving plate 47 slides on the second guide shaft 46, which guides and provides auxiliary support for the quartz tube.

[0073] When a large-sized quartz tube needs to be transported, one end of the quartz tube is first placed on the support plate 45 and the other end is placed on the support roller 54. By rotating the bolt 56, the angle of the wheel seat 53 is adjusted so that the support roller 54 can support one end of the quartz tube well. The photoelectric sensor 411 converts the light signal obtained by identifying the height difference between the support plate 45 and the rolling support assembly 5 into an electrical signal. The electrical signal is transmitted to the electrical control box, which then controls the drive motor 43 to drive the lead screw 44 to rotate, thereby moving the support plate 45 upward until the center of the quartz tube placed on the support plate 45 and the rolling support assembly 5 reaches the same horizontal line as the annealing furnace inlet. Then the quartz tube can be pushed into the annealing furnace inlet.
