Description

Technical Field

[0001] This utility model relates to the field of quartz crucible production and transportation technology, specifically to a collision-proof transportation device for quartz crucible production. Background Technology

[0002] Quartz crucibles are essential consumables in the production processes of industries such as semiconductors and photovoltaics. Their main component is silicon dioxide, which possesses characteristics such as high purity, high temperature resistance, and good chemical stability. However, quartz crucibles are brittle and hard, and are easily damaged by collisions and vibrations during production, handling, and transportation. Damaged quartz crucibles not only affect production progress but also increase production costs and result in resource waste.

[0003] Currently, the most common methods for transporting quartz crucibles on the market involve simple pallet support or frame fixation. These transport devices have several shortcomings: First, their fixed structure makes them difficult to adapt to quartz crucibles of different specifications and sizes, resulting in poor versatility and failing to meet the diverse production needs of enterprises. Second, they lack sufficient cushioning and shock absorption measures; during transport, when encountering bumps or vibrations, the quartz crucibles are prone to collisions with the transport device or other crucibles, leading to damage. Third, the transport devices have poor maneuverability and are not flexible in steering, making them difficult to move in the narrow and complex environments of production workshops, and easily causing collisions due to improper operation.

[0004] In light of this, we propose a collision-resistant transportation device for the production of quartz crucibles. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a collision-proof transportation device for quartz crucible production.

[0006] The technical solution of this utility model is:

[0007] A collision-proof transport device for quartz crucible production includes a vehicle platform. Several equally spaced limiting frames are fixedly installed on the top of the vehicle platform. Each limiting frame includes two lower base plates and an upper base plate with adjustable spacing. An upper stabilizing plate and a lower stabilizing plate with adjustable spacing are provided between the two base plates. The lower stabilizing plate is fixed to the top of the lower base plate. A connecting block is integrally formed at the center of the top of the upper stabilizing plate. An upper threaded rod is welded to the center of the top of the connecting block. The upper threaded rod passes through the upper base plate. A first adjusting knob that is threadedly connected to the upper threaded rod is rotatably installed at the center of the top of the upper base plate. Two lifting rods are symmetrically arranged between the lower base plate and the upper base plate. By setting up several equally spaced limiting frames, each of which adopts an adjustable-spacing lower base plate, upper base plate, and upper and lower stabilizing discs, and with the threaded connection between the threaded rod and the first adjustment knob, the spacing between the upper and lower stabilizing discs can be flexibly adjusted to accommodate quartz crucibles of different specifications. At the same time, the symmetrical arrangement of the two lifting rods enhances the stability of the overall structure, which can form a stable clamp on the quartz crucible, effectively preventing collisions caused by shaking during transportation, and improving the versatility and anti-collision effect of the transportation device.

[0008] As a preferred technical solution, two first support blocks are symmetrically fixedly installed near the front side of the bottom of the vehicle platform, and two second support blocks are symmetrically fixedly installed near the rear side. Each first support block has a straight wheel rotatably mounted on it, and each second support block has a swivel wheel mounted on its bottom. By setting directional rotatable straight wheels on the front side of the bottom of the vehicle platform and flexible swivel wheels on the rear side, the transportation device can maintain the stability of straight-line transportation while achieving flexible steering. This facilitates operation in complex environments such as production workshops, reduces the risk of collisions caused by inconvenient steering, and improves the ease of operation and transportation safety of the device.

[0009] As a preferred technical solution, the bottom of the omnidirectional wheel is flush with the bottom of the straight wheel, ensuring that the vehicle platform remains level during transportation.

[0010] As a preferred technical solution, a trolley handle is fixedly installed on the top of the vehicle platform near the rear side. Two diagonal braces are integrally formed symmetrically on the front side of the trolley handle, with the end of each brace away from the handle fixed to the top of the vehicle platform. The fixed installation of the trolley handle, reinforced with the diagonal braces, provides a stable grip for the operator. The diagonal braces enhance the structural strength of the connection between the trolley handle and the vehicle platform, preventing the device from becoming uncontrollable due to handle wobbling during operation, reducing collisions caused by unstable operation, and improving the controllability of the transportation process.

[0011] As a preferred technical solution, the lifting rod includes an outer sleeve fixed to the top of the lower base plate, a lower threaded rod slidably installed inside the outer sleeve, and a second adjusting knob rotatably installed on the top of the outer sleeve and threadedly connected to the lower threaded rod. The lifting rod adopts a combination structure of the outer sleeve, the lower threaded rod, and the second adjusting knob. By rotating the second adjusting knob, the height of the lifting rod can be precisely adjusted, in conjunction with the height adjustment of the stabilizing plate.

[0012] As a preferred technical solution, the first adjustment knob has two first drive rods integrally formed symmetrically on its outer circumference, and the second adjustment knob has two second drive rods fixedly installed symmetrically on its outer circumference. The first and second drive rods are respectively provided on the first and second adjustment knobs, allowing operators to easily adjust the knobs by rotating the drive rods, thus reducing the difficulty of adjustment.

[0013] As a preferred technical solution, a fixing hole is provided at each of the four corners of the lower base plate, and the lower base plate is fixed to the top of the vehicle platform with bolts. By providing fixing holes at the four corners of the lower base plate and using bolts for fixation, the restraint frame can be stably installed on the vehicle platform, preventing the restraint frame from shifting or falling off due to vibration during transportation.

[0014] As a preferred technical solution, when the lifting rod is retracted to its shortest length and the upper threaded rod is at its lowest position, the upper stabilizing plate contacts the lower stabilizing plate. This ensures that the upper and lower stabilizing plates are in contact when the lifting rod is retracted to its shortest length and the upper threaded rod is at its lowest position. This guarantees that the upper and lower stabilizing plates can fit tightly together when the device is not in use or when transporting small crucibles, preventing noise or wear caused by structural shaking. It also provides a stable foundation for placing small crucibles, optimizing the space utilization and structural stability of the device.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This utility model, by setting up several equally spaced limiting frames, each of which adopts a structure with an adjustable-spacing lower base plate, upper base plate, and upper and lower stabilizing discs, and in conjunction with the threaded connection between the upper threaded rod and the first adjusting knob, achieves flexible adjustment of the spacing between the upper and lower stabilizing discs, which can be adapted to quartz crucibles of different specifications. At the same time, the symmetrical arrangement of the two lifting rods enhances the stability of the overall structure, which can form a stable clamp for the quartz crucible, effectively preventing collisions caused by shaking during transportation, and improving the versatility and anti-collision effect of the transportation device.

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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 This utility model provides a technical solution:

[0025] A collision-proof transport device for quartz crucible production includes a platform 1. Several equally spaced limiting frames 2 are fixedly installed on the top of the platform 1. Each limiting frame 2 includes two adjustable lower base plates 20 and an upper base plate 21. An adjustable upper stabilizing plate 24 and a lower stabilizing plate 23 are provided between the two base plates. The lower stabilizing plate 23 is fixed to the top of the lower base plate 20. A connecting block 240 is integrally formed at the center of the top of the upper stabilizing plate 24. An upper threaded rod 25 is welded at the center of the top of the connecting block 240. The upper threaded rod 25 passes through the upper base plate 21. A first adjusting knob 26, which is threadedly connected to the upper threaded rod 25, is rotatably installed at the center of the top of the upper base plate 21. Two lifting rods 22 are symmetrically arranged between the lower base plate 20 and the upper base plate 21. By setting up several equally spaced limiting frames 2, each limiting frame 2 adopts a structure with an adjustable lower base plate 20, an upper base plate 21, and upper and lower stabilizing plates 23. With the threaded connection between the upper threaded rod 25 and the first adjusting knob 26, the spacing between the upper and lower stabilizing plates 23 can be flexibly adjusted, which can adapt to quartz crucibles of different specifications. At the same time, the symmetrical arrangement of the two lifting rods 22 enhances the stability of the overall structure, which can form a stable clamp for the quartz crucible, effectively preventing collisions caused by shaking during transportation, and improving the versatility and anti-collision effect of the transportation device.

[0026] In a preferred embodiment, two first support blocks 10 are symmetrically fixedly installed near the front of the bottom of the vehicle platform 1, and two second support blocks 12 are symmetrically fixedly installed near the rear. Each first support block 10 is rotatably mounted with a straight wheel 11, and each second support block 12 is mounted with a swivel wheel 13 at its bottom. By providing directional rotatable straight wheels 11 on the front side of the bottom of the vehicle platform 1 and flexible swivel wheels 13 on the rear side, the transport device can maintain the stability of straight-line transport while also achieving flexible steering. This facilitates operation in complex environments such as production workshops, reduces the risk of collisions caused by inconvenient steering, and improves the ease of operation and transport safety of the device.

[0027] As a preferred embodiment, the bottom of the omnidirectional wheel 13 is flush with the bottom of the straight wheel 11, ensuring that the vehicle platform 1 remains level during transportation.

[0028] In a preferred embodiment, a trolley handle 3 is fixedly installed on the top of the vehicle platform 1 near the rear. Two symmetrical, integrally formed diagonal braces 30 are formed on the front side of the trolley handle 3, with one end of each brace 30 fixed to the top of the vehicle platform 1 away from the handle 3. The fixed installation of the trolley handle 3, reinforced with the diagonal braces 30, provides a stable grip for the operator. The diagonal braces 30 enhance the structural strength of the connection between the trolley handle 3 and the vehicle platform 1, preventing the device from becoming uncontrollable due to wobbling of the handle 3 during operation, reducing collisions caused by unstable operation, and improving the controllability of the transportation process.

[0029] In a preferred embodiment, the lifting rod 22 includes an outer sleeve rod 220 fixed to the top of the lower base plate 20. A threaded rod 221 is slidably mounted inside the outer sleeve rod 220. A second adjusting knob 222, threadedly connected to the threaded rod 221, is rotatably mounted on the top of the outer sleeve rod 220. The lifting rod 22 adopts a combination structure of the outer sleeve rod 220, the threaded rod 221, and the second adjusting knob 222. By rotating the second adjusting knob 222, the height of the lifting rod 22 can be precisely adjusted, in conjunction with the height adjustment of the stabilizing disc 24.

[0030] In a preferred embodiment, the first adjustment knob 26 has two first drive rods 27 integrally formed symmetrically on its outer circumference, and the second adjustment knob 222 has two second drive rods 223 fixedly installed symmetrically on its outer circumference. The first and second drive rods 223 are respectively provided on the first and second adjustment knobs 222, making it easier for operators to adjust the knobs by rotating the drive rods, thus reducing the difficulty of adjustment.

[0031] As a preferred embodiment, a fixing hole is provided at each of the four corners of the lower base plate 20, and the lower base plate 20 is fixed to the top of the vehicle plate 1 by bolts. By providing fixing holes at the four corners of the lower base plate 20 and fixing it with bolts, the restraining frame 2 can be stably installed on the vehicle plate 1, preventing the restraining frame 2 from shifting or falling off due to vibration during transportation.

[0032] In a preferred embodiment, when the lifting rod 22 is retracted to its shortest length and the upper threaded rod 25 is moved to its lowest position, the upper stabilizing plate 24 contacts the lower stabilizing plate 23. This ensures that the upper stabilizing plate 24 contacts the lower stabilizing plate 23 when the lifting rod 22 is retracted to its shortest length and the upper threaded rod 25 is at its lowest position. This guarantees that the upper and lower stabilizing plates 23 can fit tightly together when the device is not in use or during the transport of small crucibles, preventing noise or wear caused by structural wobbling. It also provides a stable foundation for placing small crucibles, optimizing the space utilization and structural stability of the device.

[0033] When using the anti-collision transportation device for quartz crucible production of this utility model, firstly, according to the specifications of the quartz crucible to be transported, the limiting frame 2 is adjusted to achieve a suitable fixation of the crucible. The operator can rotate the first drive rod 27 on the first adjustment knob 26, and use the threaded engagement between the upper threaded rod 25 and the first adjustment knob 26 to drive the upper stabilizing plate 24 to move up and down. At the same time, the operator rotates the second drive rod 223 on the second adjustment knob 222, and adjusts the height of the lifting rod 22 through the threaded connection between the lower threaded rod 221 and the second adjustment knob 222. The dual adjustment creates a clamping space between the upper stabilizing plate 24 and the lower stabilizing plate 23 that is suitable for the size of the crucible, ensuring that the crucible is stably clamped between the two and avoiding shaking due to excessive gaps during transportation.

[0034] Next, the operator holds the trolley handle 3 to push the device. The straight wheel 11 on the front side of the bottom of the trolley 1 ensures the stability of straight transport, while the swivel wheel 13 on the rear side enables flexible steering. The bottoms of both are flush to ensure that the trolley 1 is always horizontal. The trolley handle 3, reinforced by the diagonal brace 30, makes the device easy to operate in the complex environment of the workshop and reduces the risk of collision caused by unstable steering or operation.

[0035] The entire process utilizes an adjustable clamping structure, a stable support and fixing method, and a flexible and controllable movement design to ensure the safe transport of quartz crucibles of different specifications and effectively prevent collision damage.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
