Description

Technical Field

[0001] The present application relates to the technical field of transport racks, and in particular to a rack that is easy to transport. Background Art

[0002] A single crystal furnace is a device that uses a graphite heater to melt polycrystalline materials such as polysilicon in an inert gas environment and grows single crystals without dislocation using the Czochralski method. In the production process of single crystal silicon, the single crystal furnace must first be evacuated with a vacuum pump to keep the single crystal furnace in a high vacuum state, remove excess harmful gases, and then fill it with inert gas as a protective gas. After that, the graphite heater in the single crystal furnace is used to heat and melt the block polycrystalline silicon material placed in the quartz crucible to complete the production of single crystal silicon. In the production process of single crystal silicon, the single crystal furnace must be continuously evacuated and continuously filled with inert protective gas.

[0003] After the single crystal furnace is installed on the existing rack for installing a single crystal furnace, the rack is fixed by installing the rack at a specified position. When the rack and the single crystal furnace as a whole need to be moved, a lifting device is required for transportation. Therefore, the existing rack for installing a single crystal furnace is not convenient for transporting the single crystal furnace. Utility Model Content

[0004] Based on this, it is necessary to provide a rack that is easy to transport to address the problem that traditionally, when the rack and the single crystal furnace are moved as a whole, a lifting device is required for transportation, and therefore the existing rack for installing the single crystal furnace is not convenient for transporting the single crystal furnace.

[0005] The present application provides a rack that is easy to transport, comprising:

[0006] Support frame;

[0007] A hand-held frame, arranged close to the top of the support frame, the hand-held frame is sleeved on the support frame, and the hand-held frame is fixedly connected to the support frame;

[0008] A plurality of support columns are provided, each of which is provided at the bottom of the support frame, and each of which is fixedly connected to the support frame;

[0009] Universal wheels are provided in plurality, the number of the universal wheels is the same as the number of the support columns, and one universal wheel is slidably provided on one support column;

[0010] A driving assembly is arranged at the bottom of the support frame, the driving assembly is arranged between the plurality of support columns, each of the universal wheels is rotationally connected to the driving assembly, and the driving assembly is used to drive the universal wheels to slide along the support columns.

[0011] The present application relates to a rack that is convenient for transportation. By starting the driving component to drive a plurality of universal wheels to slide synchronously along a plurality of support columns, when each universal wheel moves along the corresponding support column towards the support frame, each universal wheel will retract into the corresponding support column, so that the plurality of support columns directly contact the ground, limiting the position of the entire rack and making it immovable. When each universal wheel moves along the corresponding support column away from the support frame, each universal wheel will extend out of the bottom of the corresponding support column to contact the ground, facilitating the movement of the entire rack.

[0023] To make the objectives, technical solutions and advantages of this application more clear and understandable, the following further details this application in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely used to explain this application and are not intended to limit this application.

[0024] As Figure 1 shown, in an embodiment of this application, the transport-friendly frame includes a support frame 11, a handrail 12, support columns 13, a plurality of universal wheels 14, and a drive assembly 15.

[0025] The handrail 12 is disposed near the top of the support frame 11. The handrail 12 is sleeved on the support frame 11. The handrail 12 is fixedly connected to the support frame 11.

[0026] A plurality of support columns 13 are provided. Each of the support columns 13 is disposed at the bottom of the support frame 11. Each of the support columns 13 is fixedly connected to the support frame 11.

[0027] A plurality of universal wheels 14 are provided. The number of the universal wheels 14 is the same as the number of the support columns 13. One of the universal wheels 14 is slidably disposed on one of the support columns 13.

[0028] The drive assembly 15 is disposed at the bottom of the support frame 11. The drive assembly 15 is disposed between a plurality of the support columns 13. Each of the universal wheels 14 is rotatably connected to the drive assembly 15. The drive assembly 15 is used to drive the universal wheels 14 to slide along the support columns 13.

[0029] Specifically, the size of the universal wheel 14 is set to be able to freely extend or retract into the support column 13 corresponding to the universal wheel 14. The universal wheel 14 specifically includes a sliding support plate that slides relative to the support column 13 and a runner part. The runner part is disposed at the bottom of the sliding support plate, and the runner part is rotatably connected to the sliding support plate.

[0030] In this embodiment, by starting the drive assembly 15 to drive a plurality of universal wheels 14 to slide synchronously along a plurality of support columns 13, when each of the universal wheels 14 moves along the corresponding support column 13 towards the support frame 11, each of the universal wheels 14 will retract into the corresponding support column 13, thereby enabling a plurality of support columns 13 to directly contact the ground and limiting the position of the entire frame from moving. When each of the universal wheels 14 moves along the corresponding support column 13 away from the support frame 11, each of the universal wheels 14 will extend out of the bottom of the corresponding support column 13 to contact the ground, facilitating the movement of the entire frame.

[0031] As Figure 2As shown, in an embodiment of the present application, the driving assembly 15 includes a support member 151, a power motor 152, a driving turntable 153, a plurality of synchronizing rods 154, and a plurality of adapter rods 155.

[0032] The support member 151 is disposed at the bottom of the support frame 11. The support member 151 is also disposed between a plurality of the support columns 13. Each of the support columns 13 is fixedly connected to the support member 151.

[0033] The power motor 152 is disposed between the support member 151 and the support frame 11. The power motor 152 is fixedly connected to the support frame 11.

[0034] The driving turntable 153 is disposed between the power motor 152 and the support member 151. The power motor 152 is used to drive the driving turntable 153 to rotate.

[0035] A plurality of synchronizing rods 154 are provided. The number of the synchronizing rods 154 is the same as the number of the universal wheels 14. Each of the synchronizing rods 154 sequentially passes through the driving turntable 153 and the support member 151. Each of the synchronizing rods 154 is slidably connected to the support member 151. Each of the synchronizing rods 154 is slidably connected to the driving turntable 153.

[0036] A plurality of adapter rods 155 are provided. The adapter rods 155 are disposed at the bottom of the support member 151. The number of the adapter rods 155 is the same as the number of the synchronizing rods 154. One end of each of the adapter rods 155 is rotatably connected to one of the synchronizing rods 154. The other end of each of the adapter rods 155 is rotatably connected to one of the universal wheels 14.

[0037] Specifically, the moving direction of each is to approach the axis of the driving turntable 153 simultaneously or to move away from the axis of the driving turntable 153 simultaneously; the support member 151 is disposed in a plane, and this plane is parallel to the horizontal plane.

[0038] In this embodiment, the power motor 152 is started to drive the driving turntable 153 to rotate. Further, the rotation of the driving turntable 153 will drive a plurality of synchronizing rods 154 to slide on the support member 151. The movement of the synchronizing rods 154 further drives the adapter rods 155 to swing. Since one end of the adapter rod 155 is in a fixed horizontal plane, the universal wheel 14 will be driven to slide along the support column 13.

[0039] As Figure 3 shown, in an embodiment of the present application, the support member 151 includes a support disk 151a and a support rod 151b.

[0040] The supporting plate 151 a is disposed at the bottom of the driving rotating plate 153 .

[0041] The support rods 151b are provided in plurality. The number of the support rods 151b is the same as the number of the support columns 13. One end of each of the support rods 151b is fixedly connected to the outer circumferential surface of the support plate 151a. The other end of each of the support rods 151b is fixedly connected to one of the support columns 13.

[0042] In this embodiment, the tops of the multiple support columns 13 are fixedly connected to the support frame 11, and the multiple support columns 13 are further connected through multiple support rods 151b and support plates 151a, thereby enhancing the stability of the connection between the support columns 13 and the support frame 11.

[0043] like Figure 3 As shown, in one embodiment of the present application, each of the support rods 151 b is provided with a first position limiting channel 16 . Each of the synchronization rods 154 passes through one of the first position limiting channels 16 and is connected to the transfer rod 155 .

[0044] In this embodiment, the direction in which the length of the first limiting channel 16 extends is parallel to the direction in which the length of the support rod 151 b extends.

[0045] like Figure 4 As shown, in one embodiment of the present application, the driving turntable 153 includes a turntable body 153a and a plurality of first driving channels 153b.

[0046] The middle portion of the turntable body 153a is fixedly connected to the power motor 152 .

[0047] The first driving channels 153b are provided in plurality, and the number of the first driving channels 153b is the same as the number of the universal wheels 14. The first driving channels 153b penetrate the turntable body 153a.

[0048] like Figure 4 As shown, in one embodiment of the present application, one end of the first driving channel 153b in the direction of length extension is arranged near the outer circumference of the turntable body 153a. The other end of the first driving channel 153b in the direction of length extension is arranged near the axis of the turntable body 153a.

[0049] like Figure 4 As shown, in one embodiment of the present application, one of the synchronization rods 154 passes through one of the first driving channels 153 b.

[0050] In this embodiment, since each synchronizing rod 154 passes through a first driving channel 153b and also passes through a first limiting channel 16, and the first driving channel 153b is inclined and rotates with the turntable body 153a, while the first limiting channel 16 is straight and fixed in position, when the turntable body 153a rotates, each first driving channel 153b drives a synchronizing rod 154 to move along a first limiting channel 16 in a direction approaching or departing from the axis of the turntable body 153a.

[0051] As Figure 4 shown, in an embodiment of the present application, a second limiting channel 17 is formed on the end surface of each support column 13 close to the turntable body 153a. The universal wheel 14 is slidably connected to the second limiting channel 17.

[0052] In this embodiment, the length extension direction of the second limiting channel 17 is the same as that of the support column 13.

[0053] As Figure 4 and Figure 5 shown, in an embodiment of the present application, a first positioning channel 18 is formed in each second limiting channel 17, a first positioning slider 19 is slidably disposed in each first positioning channel 18, and each first positioning slider 19 is fixedly connected to a universal wheel 14.

[0054] As Figure 4 and Figure 5 shown, in an embodiment of the present application, the cross-section of the first positioning channel 18 is T-shaped, and the cross-section of the first positioning slider 19 is T-shaped and matches the first positioning channel 18.

[0055] In this embodiment, by setting the cross-section of the first positioning channel 18 to be T-shaped and the cross-section of the first positioning slider 19 sliding in the first positioning channel 18 to be T-shaped and matching the first positioning channel 18, and each first positioning slider 19 is fixedly connected to a universal wheel 14, the stability of the universal wheel 14 during movement is further improved.

[0056] The technical features of the above-described embodiments can be combined arbitrarily, and there is no limitation on the execution order of the method steps. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0057] The above-described embodiments merely represent several implementation manners of the present application. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all fall within the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the appended claims.
