[0036] The specific embodiments of the utility model will be described in further detail below in combination with the drawings and examples. The following examples are used to illustrate the utility model, but not to limit the scope of the utility model.

[0038] In the embodiment of the utility model, by designing two groups of ground fork frame 12 in C-shaped steel structure main body 1, ground fork frame 12 can be pushed into machine table foot support layer 30, so that mobile seat 4 above ground fork frame 12 is indirectly moved to machine table 10, providing position support for subsequent quartz tube replacement operation;Mobile seat 4 can be moved horizontally along slide rail seat 14 under the drive of push-pull drive 5, so as to meet the problem of insufficient working direction length in narrow space use process;Heavy-duty universal wheel 8 enables the device to be quickly and conveniently moved in the working site, improving the operation efficiency;The cooperation of heavy-duty foot 9 and support column 2 can ensure the stability of the device during operation, avoid displacement or inclination of the device, and further improve the safety of operation;Lifting platform 6 can provide a higher and stable working surface for the operator, thereby effectively reducing the risk of group falling of personnel during operation;Quartz tube holder 7 is detachably installed above lifting platform 6, and can be used to place quartz tube, and under the cooperation of lifting platform 6, quartz tube can be stably lifted to a predetermined height, not only reducing the risk of collision and damage of quartz tube, but also reducing the labor intensity of operators.

[0039] Further, the end of ground fork frame 12 away from support seat 11 is equipped with a plurality of bearing rollers 121, and the bottom end plane of bearing roller 121 is coplanar with the support bottom surface of heavy-duty universal wheel 8.

[0040] Specifically, the plurality of bearing rollers 121 and the two groups of heavy-duty universal wheels 8 jointly act to cooperatively realize the quick and stable movement of the device. The 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.

[0041] Further, the support column 2 is hinged at the rear lower end of the slide rail seat 14, and the support column 2 is movably connected to one side of the support seat 11 through an adjustable pull rod 3. The end of the adjustable pull rod 3 away from the support column 2 is movably connected to the front 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.

[0042] Specifically, when the inner facility 50 is installed in the machine table 10, it will cause the support column 2 to be unable to directly pass over the obstacle to 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 which 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. The folding method enables the support column 2 to smoothly pass over the inner facility 50 or other obstacles in the machine table 10. After the support column 2 reaches the inner side of the machine table 10, the adjustable pull rod 3 is reconnected 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, thereby ensuring that the support column 2 can stably support the slide rail seat 14, and then indirectly provide stable position support for the moving seat 4 and the lifting platform 6.

[0043] Further, the support column 2 adopts a segmented structure, including an upper column body 21 and a lower threaded adjusting rod 23. The upper end of the column body 21 is hinged with an ear seat 22, and the ear seat 22 is fixedly arranged at 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 through a threaded fitting mode, and the lower end of the threaded adjusting rod 23 is fixedly connected with a bottom disc 24.

[0044] 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 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, thereby ensuring that the support column 2 can be firmly abutted on the sleeper 40 of the inner bottom surface of the machine table 10, thereby providing stable support force.

[0045] Further, the lower end front side of the slide rail seat 14 is fixedly provided with a fixed plate 141 perpendicular to the bottom surface of the slide rail seat 14, a fixed hole 1411 is formed through the fixed plate 141, the fixed lug 211 is fixedly connected to the lower end of the side of the stand column body 21 close to the adjustable pull rod 3, the adjustable pull rod 3 comprises a main sleeve 31, a pull rod one 32 and a pull rod two 34, the pull rod one 32 is adjustably connected to one end of the main sleeve 31 close to the support stand column 2 in a threaded cooperation manner, a limiting rod one 33 is fixedly arranged on one side of the pull rod one 32, the end of the limiting rod one 33 away from the pull rod one 32 penetrates through the fixed lug 211 and is threadedly sleeved with a limiting nut one 331, the pull rod two 34 is adjustably connected to the end of the main sleeve 31 away from the support stand column 2 in a threaded cooperation manner, a limiting rod two 35 is fixedly arranged on one side of the pull rod two 34, the length of the limiting rod two 35 is greater than the length of the limiting rod one 33, and the end of the limiting rod two 35 away from the pull rod two 34 penetrates through the fixed hole 1411 and is threadedly sleeved with a limiting nut two 351.

[0046] Specifically, in actual application, the operation personnel can adjust the overall length of the adjustable pull rod 3 according to the actual position of the support stand column 2. Specifically, the overall length of the adjustable pull rod 3 can be adjusted by changing the length of the pull rod one 32 or the pull rod two 34 extending into the main sleeve 31. When it is needed to disconnect the adjustable pull rod 3 from the support stand column 2, the limiting nut one 331 outside the limiting rod one 33 is unscrewed, and then the adjustable pull rod 3 is pushed inward until the limiting rod one 33 is separated from the fixed lug 211, at this time, the adjustable pull rod 3 is disconnected from the support stand column 2, and the separation operation is completed. When it is needed to reconnect the adjustable pull rod 3 with the support stand column 2, the adjustable pull rod 3 is moved outward so that the limiting rod one 33 penetrates through the fixed lug 211. Then, the limiting nut one 331 is used to threadedly sleeve the outside of the limiting rod one 33, so as to ensure the stable connection between the limiting rod one 33 and the fixed lug 211, thereby indirectly realizing the fixation of the adjustable pull rod 3 to the support stand column 2. In addition, the length of the limiting rod two 35 is greater than the length of the limiting rod one 33, which functions to slide the limiting rod one 33 relative to the fixed lug 211 and slide the limiting rod two 35 relative to the fixed hole 1411 when the adjustable pull rod 3 is moved inward. When the limiting rod one 33 is gradually separated from the fixed lug 211, the limiting rod two 35 does not separate from the fixed hole 1411 due to the length of the limiting rod two 35 being greater than the length of the limiting rod one 33 and the action of the limiting nut two 351.

[0047] Further, the rear side of the fixed seat 13 is formed with a square through slot 131, the push-pull driving member 5 comprises a flat push hydraulic cylinder 51 and a flat push hydraulic handle mechanism 52, the cylinder end of the flat push hydraulic cylinder 51 is fixedly arranged 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 slot 131 and is fixedly connected to the front side of the moving seat 4, and the flat push hydraulic handle mechanism 52 is fixedly arranged on the front side of the support seat 11.

[0048] Specifically, the operator can conveniently control the extension and retraction of the piston rod of the hydraulic cylinder 51 by the hydraulic handle mechanism 52, thereby indirectly pushing the moving base 4 to move smoothly on the two sets of slide rail bases 14.

[0049] Further, the lifting platform 6 comprises a platform base 61 and a plurality of double-shear hydraulic supports 62 between the platform base 61 and the moving base 4. The lower front side of the double-shear hydraulic support 62 is hinged to the inner side of the moving base 4, the lower rear side of the double-shear hydraulic support 62 is slidingly connected to the inner side of the moving base 4, the upper front side of the double-shear hydraulic support 62 is hinged to the lower inner side of the platform base 61, the upper rear side of the double-shear hydraulic support 62 is slidingly connected to the lower inner side of the platform base 61, and the inner side of the double-shear hydraulic support 62 is provided with a lifting hydraulic cylinder 63 for driving the double-shear hydraulic support 62 to lift. The front side of the support base 11 is fixedly provided with a lifting hydraulic handle mechanism 631.

[0050] Specifically, the operator can conveniently control the extension and retraction of the piston rod of the hydraulic cylinder 51 by the hydraulic handle mechanism 52, thereby indirectly pushing the moving base 4 to move smoothly on the two sets of slide rail bases 14.

[0051] Further, the double-shear hydraulic support 62 comprises four sets of X-shaped supports 621, which are symmetrically arranged in pairs. The symmetric arrangement can effectively disperse the load and prevent the support from losing stability due to uneven stress during lifting. The two sets of X-shaped supports 621 on the same side are distributed vertically and hinged to each other, and the hinge points of the two sets of X-shaped supports 621 on the left and right sides are fixed by a horizontal connecting rod 622. The rear side of the lower two sets of X-shaped supports 621 is fixedly provided with a lower horizontal support beam 623, and the front side of the upper two sets of X-shaped supports 621 is 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.

[0052] Further, the quartz tube holder 7 comprises a base 71 and a tube holder 73. The base 71 is detachably connected to the upper surface of the platform base 61 by bolts, and the tube holder 73 is rotationally connected to the upper end of the base 71 by 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, and four ear plates 731 are fixedly arranged at the four corners of the tube holder 73. An active slot 7311 is formed through the surface of the ear plate 731, the upper end of the short threaded rod 74 penetrates the active slot 7311, and two sets of fixed nuts 741 are threadedly arranged outside the short threaded rod 74 and abut against the upper surface and the lower surface of the ear plate 731, respectively.

[0053] Specifically, the base 71 is fixed with the platform base 61 by bolts. When the quartz tube needs to be transported, the base 71 can be conveniently installed on the platform base 61 by bolts. When the operator needs to be transported, the base 71 can be removed, which improves the flexibility of the device. Secondly, the tube holder 73 for placing the quartz tube is rotatably connected with the base 71 through the rotating shaft 72, so that the tube holder 73 can adjust the inclination angle according to the actual situation. Specifically, when the lifting platform 6 lifts the quartz tube to a certain height, if the quartz tube is not concentric with the furnace body port 20, the inclination angle of the tube holder 73 can be adjusted at this time, so that the quartz tube is concentric with the furnace body port 20. In this way, the operator can directly push the quartz tube into the furnace body along the tube holder 73 without the need for the operator to carry, which greatly improves the operation efficiency and reduces the labor intensity. The inclination angle adjustment mode of the tube holder 73: loosen the fixing nut 741 on the upper and lower surfaces of the ear plate 731. At this time, the ear plate 731 can adjust the relative position with the short threaded rod 74 under the action of the movable groove 7311, so as to drive the tube holder 73 to complete the inclination adjustment. After adjustment, the fixing nut 741 is tightened again to abut against the upper and lower surfaces of the ear plate 731.

[0054] Further, the heavy load foot 9 includes an adjusting column 91 and a foot base 92. The adjusting column 91 is fixedly arranged at the lower end of the front side of the support base 11, and the foot base 92 is adjustably connected to the lower end of the adjusting column 91 by threaded cooperation.

[0055] Specifically, after the device moves to the specified position, the operator can adjust the overall height of the heavy load foot 9 to make the device reach a stable state. This adjustment process makes the heavy load universal wheel 8 empty, so as to ensure that the heavy load universal wheel 8 is no longer in contact with the ground, thereby providing more stable support for the device. In order to realize this operation, the operator only needs to rotate the foot base 92, so as to easily change the relative position between the foot base 92 and the adjusting column 91, thereby accurately adjusting the height of the heavy load foot 9.

[0056] Working principle: first, the operator first pushes the device to the machine table 10 beside the vacuum furnace tube equipment, and multiple sets of the device can be used simultaneously according to actual operation requirements. Second, the two groups of C-shaped steel structure main bodies 1 are pushed into the machine table ground support layer 30, and at this time the moving seat 4 is synchronously moved into the machine table 10 (in the pushing process, whether the folding support column 2 needs to be folded can be selected according to whether there are obstacles in the inside entrance of the machine table 10). Third, 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, manually operate the horizontal pushing hydraulic handle mechanism 52 to make the horizontal pushing hydraulic cylinder 51 horizontally push the moving seat 4, so as to further move to the operation position. Fourth, the sleeper 40 is placed at the bottom of the machine table 10, and the overall support height of the support column 2 is adjusted, so that the bottom disc 24 of the support column 2 presses the sleeper 40. Then the position of the support column 2 is fixed through the adjustable pull rod 3. Then adjust the heavy load foot 9, so that the heavy load universal wheel 8 moves away from the ground. Fifth, according to different use requirements of each group of devices, whether to install the quartz tube support 7 is selected. If the operator needs to be transported, the quartz tube support 7 does not need to be installed on the platform seat 61. If the quartz tube needs to be taken and placed, the base 71 in the quartz tube support 7 needs to be bolted on the platform seat 61. Sixth, the operator outside the machine table 10 manually operates the lifting hydraulic handle mechanism 631, and slowly lifts the platform seat 61 through the lifting hydraulic cylinder 63 and the double shear hydraulic bracket 62, so as to lift the operator or the quartz tube support 7 on the platform seat 61 to the working height. Seventh, 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 make it descend, and then takes down the old quartz tube and places the new quartz tube on the tube support 73. Eighth, the operator outside the machine table 10 again operates the lifting platform 6 to rise to the specified height, and then the operator installs the new quartz tube into the furnace body. In this way, the replacement of the quartz tube is completed.

[0057] It should be particularly pointed out that the horizontal pushing hydraulic cylinder 51 and the horizontal pushing hydraulic handle mechanism 52, the lifting hydraulic cylinder 63 and the lifting hydraulic handle mechanism 631 in the embodiment are connected through an oil circuit system, and the horizontal pushing hydraulic handle mechanism 52 and the lifting hydraulic handle mechanism 631 adopt a manual hydraulic pump. The core is to drive the flow of hydraulic oil through a manual handle, so as to control the extension and retraction of the hydraulic cylinder. Since these components are prior art, and their internal structure and basic working principle have been widely applied, the embodiment will not be described in detail.

[0058] The above are only preferred embodiments of the present application, and are not used to limit the present application, and it should be pointed out that, for ordinary skilled in the art, without departing from the technical principles of the present application, can make a number of improvements and variations, these improvements and variations should also be considered as the protection scope of the present application.
