Description

Technical Field

[0001] The present invention relates to the technical field of solar cell manufacturing, and particularly relates to a lifting trolley for quartz tube replacement operation and its operation method. Background Art

[0002] The manufacturing process of solar cells is inseparable from vacuum furnace tube equipment, and one of the core components of the vacuum furnace tube equipment is the quartz tube. With the market technology revolution, taking TOPCON technology as an example, the number of quartz tubes used in photovoltaic manufacturing is increasing day by day. The quartz tube is made of clean and high-temperature resistant material but has a low lifespan, with an average lifespan of one quartz tube being 5 months. Therefore, photovoltaic manufacturing plants need to frequently carry out quartz tube replacement operations.

[0003] Currently, when photovoltaic manufacturing plants replace quartz tubes, most rely on manual labor to carry out handling operations in a narrow and restricted vertical space. The size of the quartz tube is relatively large, with each quartz tube being about 4 meters long, about 0.5 meters in diameter, and weighing up to about 200 kg. During handling, the operating personnel need to operate within a height range of up to about 4 meters, which undoubtedly increases the complexity and danger of the operation. Each operation requires 8 to 10 people to cooperate to ensure the smooth progress of the handling process.

[0004] However, due to the limitation of the operation space and the lack of a stable stepping support point, the operating personnel face a relatively high risk of group falling, and the potential safety hazards are relatively serious. At the same time, during the manual handling process, the quartz tube may be damaged due to collision or improper operation. In addition, due to frequent handling operations, the labor intensity of the operating personnel has also increased significantly. Summary of the Invention

[0023] An operation method of a lifting trolley for quartz tube replacement operation includes the following steps:

[0024] The operator first pushes multiple sets of lifting trolleys for quartz tube replacement operation required to the side of the machine table of the vacuum furnace tube equipment.

[0025] Push the two sets of ground fork frames of the C-shaped steel structure main body into the machine base floor support layer. At this time, the moving seat moves into the machine base synchronously. During the pushing process, it is possible to choose whether to fold the support columns according to whether there are internal facilities at the inner entrance of the machine base;

[0026] The operator can continue to adjust the position of the moving seat extending into the machine base according to the actual operation requirements, and manually operate the horizontal push hydraulic handle mechanism to make the horizontal push hydraulic cylinder push the moving seat horizontally;

[0027] Place sleepers at the position of the inner bottom plate of the machine base, and then adjust the overall support height of the support columns so that the bottom discs of the support columns press tightly on the sleepers. Then fix the positions of the support columns through adjustable tie rods, and then adjust the heavy-duty floor bolts so that the heavy-duty universal wheels are lifted off the ground;

[0028] According to the different usage requirements of the lifting carts for each group of quartz tube replacement operations, choose whether to install quartz tube supports;

[0029] The operator outside the machine base manually operates the lifting hydraulic handle mechanism, and slowly raises the platform seat through the lifting hydraulic cylinder and the double shear fork hydraulic support, so as to raise the platform seat to the working height;

[0030] The operator takes out the old quartz tube from the furnace body opening, and then places it on the tube support. Then, the operator outside the machine base operates the lifting platform to lower it, and then removes the old quartz tube and places the new quartz tube on the tube support;

[0031] The operator outside the machine base operates the lifting platform to rise again. After rising to the specified height, the operator installs the new quartz tube into the furnace body.

[0032] All the above optional technical solutions can be combined arbitrarily, and the present invention does not elaborate on the structures after the combinations one by one.

[0033] By means of the above solutions, the beneficial effects of the present invention are as follows:

[0034] 1. By setting up a lifting platform, the present invention can provide a high and stable working surface for the operator, thus effectively reducing the risk of mass falls of personnel during the operation. When replacing the quartz tube, the quartz tube support cooperates with the lifting platform to stably lift the quartz tube to a predetermined position, which not only reduces the risk of collision damage to the quartz tube, but also reduces the labor intensity of the operator.

[0035] 2. By designing two groups of ground fork frames in the C-shaped steel structure main body, the ground fork frames can be pushed into the machine base foot support layer, thereby indirectly moving the moving seat above the ground fork frames into the machine. And under the drive of the push-pull driving member, the moving seat can move horizontally along the slide rail seat to meet the problem of insufficient working direction length during the use in a narrow space. This not only improves the space utilization efficiency but also ensures the smooth progress of the subsequent quartz tube replacement operation, providing sufficient operating space and position support for the operators.

[0036] The above description is only an overview of the technical solution of the present invention. In order to understand the technical means of the present invention more clearly and implement it according to the content of the specification, the following describes the preferred embodiments of the present invention in detail with reference to the accompanying drawings.

[0051] The following will further describe in detail the specific embodiments of the present invention in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present invention, but are not used to limit the scope of the present invention.

[0052] Please refer to Figures 1-13 , the present invention provides a lifting trolley for quartz tube replacement operation, including:

[0053] The C-shaped steel structure main body 1 is composed of a support seat 11, two groups of parallel ground fork frames 12, a group of fixed seats 13 with a front opening and a lower opening and being hollow inside, and two groups of parallel slide rail seats 14. The two groups of ground fork frames 12 are symmetrically fixed at the lower rear side of the support seat 11, the fixed seat 13 is fixed at the upper rear side of the support seat 11, and the two groups of slide rail seats 14 are symmetrically fixed at the rear side of the fixed seat 13; by designing two groups of ground fork frames 12 in the C-shaped steel structure main body 1, the ground fork frames 12 can be pushed into the machine platform floor anchor support layer 30, so that the moving seat 4 above the ground fork frames 12 can be indirectly moved into the machine platform 10, providing position support for the subsequent quartz tube replacement operation.

[0054] A moving seat 4 is slidably installed between two sets of slide rail seats 14; a push-pull driving member 5 is internally installed in the fixed seat 13 and connected to the moving seat 4, and is used to drive the moving seat 4 to move horizontally along the slide rail seat 14. Driven by the push-pull driving member 5, the moving seat 4 can move horizontally along the slide rail seat 14, so as to solve the problem of insufficient working direction length during the use in a narrow space.

[0055] A lifting platform 6 is arranged above the moving seat 4; the lifting platform 6 can provide a relatively high and stable working surface for operators, thus effectively reducing the risk of mass falls of personnel during the operation.

[0056] An anti-slip pad 64 is fixedly arranged on the upper surface of the lifting platform 6; it effectively enhances the anti-slip performance of the lifting platform 6. Especially when operators are working at heights, the anti-slip pad 64 can provide more stable support and reduce the danger caused by the sliding of the surface of the lifting platform 6.

[0057] A quartz tube support 7 is detachably connected above the lifting platform 6 and is used for placing quartz tubes, and an anti-slip pad 64 is clamped between the quartz tube support 7 and the lifting platform 6; the quartz tube support 7 is detachably installed above the lifting platform 6 and can be used to place quartz tubes. With the cooperation of the lifting platform 6, the quartz tubes can be stably lifted to a predetermined height, which not only reduces the risk of collision damage of the quartz tubes, but also reduces the labor intensity of operators.

[0058] A moving assembly includes multiple groups of load-bearing rollers 121 longitudinally arranged along the ground fork 12 and two groups of heavy-duty universal wheels 8 symmetrically installed at the lower front side of the support seat 11. Among them, the bottom plane of the load-bearing rollers 121 and the supporting bottom surface of the heavy-duty universal wheels 8 are coplanar to jointly achieve load-bearing movement; the multiple groups of load-bearing rollers 121 and the two groups of heavy-duty universal wheels 8 work together to jointly achieve the fast and stable movement of the device. The load-bearing rollers 121 can effectively share the load, while the heavy-duty universal wheels 8 provide greater flexibility and controllability, making the movement of the entire device in complex or narrow spaces more efficient and convenient.

[0059] A support assembly includes two groups of support columns 2 and two groups of heavy-duty floor bolts 9. The two groups of support columns 2 are respectively installed at the lower ends of the two groups of slide rail seats 14 and on the side far from the fixed seat 13, and the two groups of heavy-duty floor bolts 9 are installed at the lower front side of the support seat 11 and between the two groups of heavy-duty universal wheels 8; the combined use of the heavy-duty floor bolts 9 and the support columns 2 can ensure the stability of the device during the operation, avoid the displacement or inclination of the device, and further improve the safety of the operation.

[0060] Furthermore, the support column 2 is hinged to the rear side of the lower end of the slide rail seat 14. An adjustable pull rod 3 is movably connected to the side of the support column 2 close to the support seat 11. One end of the adjustable pull rod 3 away from the support column 2 is movably connected to the front side of the lower end of the slide rail seat 14, and the slide rail seat 14, the support column 2 and the adjustable pull rod 3 form a triangular support structure.

[0061] Specifically, when the internal facilities 50 are installed in the machine table 10, this will cause the support column 2 to be unable to directly cross the obstacle and reach the inner side of the machine table 10. In this case, the operator can disconnect the adjustable pull rod 3 from the support column 2. At this time, the support column 2 can rotate around the hinge point with the slide rail seat 14, and then adjust the position of the support column 2 to fold it, so that the support column 2 can smoothly cross the internal facilities 50 or other obstacles in the machine table 10 by folding. After the support column 2 reaches the inner side of the machine table 10, reconnect the adjustable pull rod 3 to the support column 2. At this time, the slide rail seat 14, the support column 2 and the adjustable pull rod 3 together form a stable triangular structure, so as to ensure that the support column 2 can stably support the slide rail seat 14, and indirectly provide a stable position support for the moving seat 4 and the lifting platform 6.

[0062] Furthermore, the support column 2 adopts a segmented structure, including the upper column body 21 and the lower threaded adjusting rod 23. An ear seat 22 is hinged to the upper end of the column body 21, and the ear seat 22 is fixed to the lower end of the slide rail seat 14. The threaded adjusting rod 23 is adjustably connected to the lower end of the column body 21 by a threaded fit, and the lower end of the threaded adjusting rod 23 is fixedly connected with a bottom disc 24.

[0063] Specifically, when the support column 2 enters the inner side of the machine table 10, the operator can manually adjust the length of the threaded adjusting rod 23, so as to change the overall length of the support column 2. By manually rotating the threaded adjusting rod 23, the operator can flexibly control the length of the threaded adjusting rod 23 extending out of the column body 21, ensuring that the support column 2 can firmly abut against the sleeper 40 on the inner bottom surface of the machine table 10, so as to provide a stable supporting force.

[0064] Further, a fixing plate 141 perpendicular to the bottom surface of the slide rail seat 14 is fixedly provided on the front side of the lower end of the slide rail seat 14. A fixing hole 1411 is penetrated through the fixing plate 141. A fixing ear 211 is fixedly connected to the lower end of the column body 21 near the adjustable pull rod 3. The adjustable pull rod 3 includes a main sleeve 31, a first pull rod 32 and a second pull rod 34. The first pull rod 32 is adjustably connected to one end of the main sleeve 31 near the support column 2 by a threaded fit. A first limiting rod 33 is perpendicularly fixed on one side of the first pull rod 32. The end of the first limiting rod 33 away from the first pull rod 32 penetrates through the fixing ear 211 and is threadedly sleeved with a first limiting nut 331. The second pull rod 34 is adjustably connected to the end of the main sleeve 31 away from the support column 2 by a threaded fit. A second limiting rod 35 is perpendicularly fixed on one side of the second pull rod 34. The length of the second limiting rod 35 is greater than that of the first limiting rod 33. The end of the second limiting rod 35 away from the second pull rod 34 penetrates through the fixing hole 1411 and is threadedly sleeved with a second limiting nut 351.

[0065] Specifically, in the actual application process, the operator can adjust the overall length of the adjustable pull rod 3 according to the actual position of the support column 2. Specifically, the overall length of the adjustable pull rod 3 can be adjusted by changing the length of the first pull rod 32 or the second pull rod 34 extending into the main sleeve 31. When it is necessary to disconnect the adjustable pull rod 3 from the support column 2, only need to unscrew the first limiting nut 331 outside the first limiting rod 33, and then push the adjustable pull rod 3 inward until the first limiting rod 33 disengages from the fixing ear 211. At this time, the adjustable pull rod 3 is disconnected from the support column 2, and the separation operation is completed. When it is necessary to reconnect the adjustable pull rod 3 to the support column 2, the adjustable pull rod 3 is moved outward so that the first limiting rod 33 passes through the fixing ear 211. Then, the first limiting nut 331 is used to be threadedly sleeved outside the first limiting rod 33 to ensure the stable connection between the first limiting rod 33 and the fixing ear 211, thereby indirectly realizing the fixation of the adjustable pull rod 3 to the support column 2. In addition, the length of the second limiting rod 35 is greater than that of the first limiting rod 33. Its function is that when the adjustable pull rod 3 is moved inward, the first limiting rod 33 and the fixing ear 211 slide relative to each other, and the second limiting rod 35 and the fixing hole 1411 also slide relative to each other. After the first limiting rod 33 gradually slips out of the fixing ear 211, due to the length of the second limiting rod 35 being greater than that of the first limiting rod 33 and under the action of the second limiting nut 351, the second limiting rod 35 will not disengage from the fixing hole 1411.

[0066] Further, a square through groove 131 is penetrated through the rear side of the fixed seat 13. The push-pull driving member 5 includes a flat push hydraulic cylinder 51 and a flat push hydraulic handle mechanism 52. The cylinder body end of the flat push hydraulic cylinder 51 is fixedly provided on the rear side of the support seat 11. The piston rod end of the flat push hydraulic cylinder 51 penetrates through the square through groove 131 and is fixedly connected to the front side of the moving seat 4. The flat push hydraulic handle mechanism 52 is fixedly provided on the front side of the support seat 11.

[0067] Specifically, the operator can conveniently manipulate the telescopic movement of the piston rod of the flat-push hydraulic cylinder 51 through the flat-push hydraulic handle mechanism 52, thereby indirectly pushing the moving seat 4 to move smoothly on the two sets of slide rail seats 14.

[0068] Furthermore, the lifting platform 6 includes a platform seat 61 and more than one set of double scissors hydraulic supports 62 located between the platform seat 61 and the moving seat 4. The anti-slip pad 64 is fixedly arranged on the upper surface of the platform seat 61. The front side of the lower end of the double scissors hydraulic support 62 is hinged to the inner side of the moving seat 4, and the rear side of the lower end of the double scissors hydraulic support 62 is slidably connected to the inner side of the moving seat 4. The front side of the upper end of the double scissors hydraulic support 62 is hinged to the inner side of the lower end of the platform seat 61, and the rear side of the upper end of the double scissors hydraulic support 62 is slidably connected to the inner side of the lower end of the platform seat 61. A lifting hydraulic cylinder 63 for driving the lifting of the double scissors hydraulic support 62 is installed inside the double scissors hydraulic support 62, and a lifting hydraulic handle mechanism 631 is fixedly arranged on the front side of the support seat 11.

[0069] Specifically, the operator can conveniently manipulate the telescopic movement of the piston rod of the lifting hydraulic cylinder 63 through the lifting hydraulic handle mechanism 631, thereby effectively controlling the lifting of the double scissors hydraulic support 62, and further realizing the precise lifting of the platform seat 61. In this way, the operator can quickly and smoothly adjust the height of the platform seat 61 according to actual needs.

[0070] Furthermore, the double scissors hydraulic support 62 includes four groups of X-shaped brackets 621. The four groups of X-shaped brackets 621 are respectively arranged in two-by-two symmetry. By symmetrically arranging, the load can be effectively dispersed to prevent the brackets from losing stability due to uneven force during the lifting process. The two groups of X-shaped brackets 621 on the same side are distributed up and down and are hinged to each other. The hinge points between the two groups of X-shaped brackets 621 on the left and right sides are fixed by a transverse connecting rod 622. The rear sides of the two groups of X-shaped brackets 621 in the lower layer are fixedly provided with a lower horizontal support beam 623, and the front sides of the two groups of X-shaped brackets 621 in the upper layer are fixedly provided with an upper horizontal support beam 624. The lower end of the lifting hydraulic cylinder 63 is hinged to the lower horizontal support beam 623, and the piston rod end of the lifting hydraulic cylinder 63 is hinged to the upper horizontal support beam 624.

[0071] Furthermore, the quartz tube support 7 includes a base 71 and a tube support 73. The base 71 is detachably connected to the upper surface of the platform seat 61 by bolts. The tube support 73 is rotatably connected to the upper end of the base 71 through a rotating shaft 72. Four short threaded rods 74 perpendicular to the upper surface of the base 71 are fixedly arranged at the four corners of the upper surface of the base 71. Ear plates 731 are fixedly arranged at the four corners of the tube support 73. An activity groove 7311 is penetrated through the surface of the ear plate 731. The upper ends of the short threaded rods 74 penetrate through the activity groove 7311, and two sets of fixing nuts 741 are threadedly sleeved on the outer sides of the short threaded rods 74. The two sets of fixing nuts 741 are respectively abutted against the upper surface and the lower surface of the ear plate 731.

[0072] Specifically, the base 71 is fixed to the platform base 61 by bolts. When it is necessary to transport the quartz tube, the base 71 can be conveniently installed on the platform base 61 using bolts. When it is necessary to transport the operator, the base 71 can be removed, improving the flexibility of the device. Secondly, the tube support 73 for placing the quartz tube is rotatably structured with the base 71 through a rotating shaft 72, enabling the tube support 73 to adjust its inclination angle according to the actual situation. Specifically, when the lifting platform 6 raises the quartz tube to a certain height, if the quartz tube is not concentric with the furnace body opening 20, at this time, the inclination angle of the tube support 73 can be adjusted so that the quartz tube is concentric with the furnace body opening 20. In this way, the operator can directly push the quartz tube into the furnace body along the tube support 73 without the need for the operator to carry it, greatly improving the operation efficiency and reducing the labor intensity. The method for adjusting the inclination angle of the tube support 73: Loosen the fixing nuts 741 on the upper and lower surfaces of the ear plate 731. At this time, under the action of the movable slot 7311, the ear plate 731 can adjust its relative position with the short threaded rod 74, thereby driving the tube support 73 to complete the inclination adjustment. After the adjustment is completed, tighten the fixing nuts 741 again to abut against the upper and lower surfaces of the ear plate 731.

[0073] Furthermore, the heavy-duty anchor bolt 9 includes an adjusting column 91 and an anchor bolt base 92. The adjusting column 91 is fixedly arranged at the lower front side of the support base 11, and the anchor bolt base 92 is adjustably connected to the lower end of the adjusting column 91 by a threaded fit.

[0074] Specifically, after the device moves to the designated position, the operator can adjust the overall height of the heavy-duty anchor bolt 9 to make the device reach a stable state. This adjustment process lifts the heavy-duty universal wheels 8 off the ground, ensuring that the heavy-duty universal wheels 8 are no longer in contact with the ground and providing a more stable support for the device. To achieve this operation, the operator only needs to rotate the anchor bolt base 92 to easily change the relative position between the anchor bolt base 92 and the adjusting column 91, thereby precisely adjusting the height of the heavy-duty anchor bolt 9.

[0075] An operation method for a lifting trolley used for quartz tube replacement operations includes the following steps:

[0076] In the first step, the operator first pushes the device to the side of the machine table 10 of the vacuum furnace tube equipment, and multiple groups of this device can be used for collaborative operations according to actual operation requirements.

[0077] In the second step, the two ground fork frames 12 of the C-shaped steel structure main body 1 are pushed into the machine table floor support layer 30, and at this time, the moving seat 4 moves synchronously into the machine table 10 (during the pushing process, it can be selected whether to fold the support column 2 according to whether there are obstacles at the inner entrance of the machine table 10).

[0078] In the third step, the operator can continue to adjust the position of the moving seat 4 extending into the machine table 10 according to the actual operation requirements, and manually operate the horizontal push hydraulic handle mechanism 52 to make the horizontal push hydraulic cylinder 51 horizontally push out the moving seat 4, so that it further moves to the operation position.

[0079] In the fourth step, place sleepers 40 at the position of the inner bottom plate of the machine table 10, and then adjust the overall support height of the support column 2 so that the bottom disc 24 of the support column 2 presses tightly on the sleepers 40. Then fix the position of the support column 2 through the adjustable pull rod 3. Then adjust the heavy-duty floor feet 9 again so that the heavy-duty universal wheels 8 are moved away from the ground.

[0080] In the fifth step, according to the different usage requirements of each group of devices, choose whether to install the quartz tube support 7. If it is necessary to transport the operator, there is no need to install the quartz tube support 7 on the platform seat 61. If it is necessary to pick up and place the quartz tube, the base 71 in the quartz tube support 7 needs to be installed on the platform seat 61 using bolts.

[0081] In the sixth step, the operator outside the machine table 10 manually operates the lifting hydraulic handle mechanism 631, and slowly raises the platform seat 61 through the lifting hydraulic cylinder 63 and the double scissor hydraulic support 62, so as to raise the operator or the quartz tube support 7 on the platform seat 61 to the working height.

[0082] In the seventh step, the operator takes out the old quartz tube from the furnace body opening 20 and then places it on the tube support 73. Then, the operator outside the machine table 10 operates the lifting platform 6 to lower it, then removes the old quartz tube, and places the new quartz tube on the tube support 73.

[0083] In the eighth step, the operator outside the machine table 10 operates the lifting platform 6 to rise again. After rising to the specified height, the operator installs the new quartz tube into the furnace body. In this way, the replacement operation of the quartz tube is completed.

[0084] It should be particularly noted that in this embodiment, the horizontal push hydraulic cylinder 51 is connected to the horizontal push hydraulic handle mechanism 52, and the lifting hydraulic cylinder 63 is connected to the lifting hydraulic handle mechanism 631 through the oil circuit system. Both the horizontal push hydraulic handle mechanism 52 and the lifting hydraulic handle mechanism 631 use manual hydraulic pumps. The core is to drive the flow of hydraulic oil by manually operating the handle, so as to control the telescopic movement of the hydraulic cylinder. Since these components are prior art and their internal structures and basic working principles have been widely applied, the internal structures and basic working principles of the above components will not be described in detail in this embodiment.

[0085] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
