Description

Technical Field

[0001] The utility model relates to the technical field of laminated furnace equipment, in particular to a gantry shear lift. Background Art

[0002] The laminated furnace uses high-temperature extrusion to bond the film to two or more pieces of glass. Laminated glass is large in size and the operating temperature of the laminated furnace is high, so a traction device is required to complete the entry and exit of the product into the furnace. The traction device must be precisely docked with the track of the laminated furnace to push or pull the product in or out.

[0003] For multi-layer laminated furnaces, it is necessary to use a lift to lift the traction device so that the traction device can dock with the rails of different layers of the laminated furnace. The existing gantry shear lift is lacking in precise docking of rails and universality of multi-layer laminated furnaces. The traction device cannot be well docked with the rails of each layer of the laminated furnace. For laminated furnaces of different heights, the lift is difficult to modify and has poor universality.

[0004] Therefore, it is necessary to design a gantry shear lift that can be used in multi-layer laminated furnaces. Utility Model Content

[0029] The specific implementation modes of the present utility model are introduced with reference to the accompanying drawings.

[0030] refer to Figure 1 The figure is a three-dimensional schematic diagram of the gantry shear lift. The left area in the figure is the guide column 3, and the upper, middle and lower areas on the right are the lifting platform 1, the fork arm 4 and the base 2 respectively. The lifting platform 1 is raised to the highest height, and the base 2 stably supports the lifting platform 1 through the fork arm 4. The lifting platform 1 moves up and down along the guide column 3 to achieve the docking of the lifting platform 1 with the different layers of the rails of the laminated furnace.

[0031] refer to Figures 1 to 5 A gantry shear lift comprises a lifting platform 1, a base 2, a guide column 3, a fork arm 4 and a lifting drive assembly 5. The lifting platform 1 is provided with a traction device 7 for cooperating with the laminated furnace to put products into and out of the furnace. The base 2 and the guide column 3 are separately arranged, the guide column 3 is vertically arranged on the outside of the base 2, the fork arm 4 is arranged between the base 2 and the lifting platform 1, one side of the lifting platform 1 is movably arranged on the guide column 3 through the guide assembly 6, the lifting drive assembly 5 is arranged on one side of the guide column 3 and is connected to the lifting platform 1 in transmission, the lifting drive assembly 5 drives the lifting platform 1 to move up and down along the guide column 3, and the fork arm 4 supports the moving lifting platform 1.

[0032] The gantry shear lift of the embodiment of the present application adopts a servo motor as the lifting motor 53, and guides the lifting platform 1 through the guide column 3 and the guide assembly 6 to ensure that the lifting platform 1 can move up and down stably and accurately, lift the product to a specified height, and accurately dock with the tracks of different layers of the laminating furnace to adapt to the multi-layer laminating furnace; the lifting platform 1 is stably supported by the fork arm 4 during the lifting process to ensure the parallelism of the lifting platform 1.

[0033] In order to stably guide the lifting platform 1 to move up and down, in this embodiment, reference Figure 4 and Figure 5 The guide assembly 6 includes a connecting block 61, a first guide wheel 62 and a second guide wheel 63. The connecting block 61 is fixedly connected to the lifting platform 1. The first guide wheel 62 and the second guide wheel 63 are spaced apart on the connecting block 61. The axial direction of the first guide wheel 62 is perpendicular to the axial direction of the second guide wheel 63.

[0034] It should be further explained that the connecting block 61 is in a horizontal "L" shape, the horizontal side above the connecting block 61 is fixedly connected to the lifting platform 1, the first guide wheel 62 is installed on the horizontal side through the L-shaped component 65, and two mounting blocks 64 are installed on the vertical side below the connecting block 61. Two nuts 55 are installed on the two mounting blocks 64 respectively, and two second guide wheels 63 are symmetrically arranged on both sides of a mounting block 64 below.

[0035] It can be understood that, with such an arrangement, the first guide wheel 62 and the second guide wheel 63 are used to stably guide the lifting platform 1 to move up and down, thereby preventing the lifting platform 1 from swinging during the lifting process.

[0036] In order to drive the lifting platform 1 to move up and down, in this embodiment, reference Figure 2 and Figure 4 The lifting drive assembly 5 includes a transmission shaft 51, a lifting screw 52, ​​and a lifting motor 53. The lifting motor 53 is fixed on the base 34 below the guide column 3. The driving end of the lifting motor 53 is provided with a transmission shaft 51. The transmission shaft 51 is transmission-connected to the lifting screw 52 arranged in the guide column 3. The nut 55 of the lifting screw 52 is connected to the connecting block 61. The lifting motor 53 drives the guide assembly 6 to move along the guide column 3 through the transmission shaft 51 and the lifting screw 52.

[0037] It should be further explained that the lifting motor 53 is a servo motor, and the base 34 of the guide column 3 is provided with an angle reducer 54, and the angle reducer 54 is arranged between the transmission shaft 51 and the upgrade screw rod. The lifting motor 53 drives the transmission shaft 51 and the lifting screw rod 52 to rotate through the angle reducer 54.

[0038] It is understandable that, with such an arrangement, the lifting motor 53 synchronously drives the two lifting screws 52 inside the two guide columns 3 to rotate through the transmission shaft 51, and the rotating lifting screws 52 drive the lifting platform 1 to move along the guide columns 3 through the nut 55 and the guide assembly 6.

[0039] In order to ensure that the guide assembly 6 and the guide column 3 have stable guiding performance, in this embodiment, reference Figure 4 and Figure 5 The lifting screw 52 is located inside the guide column 3, and an opening 31 leading to the lifting screw 52 is formed on the outer wall of the guide column 3. The inner walls on both sides of the opening 31 form a guide track 32 slidably connected to the first guide wheel 62. The guide column 3 is provided with guide grooves 33 on both sides of the opening 31, and the guide grooves 33 are slidably connected to the second guide wheel 63.

[0040] Specifically, refer to Figure 4 and Figure 5 The cross section of the guide column 3 is in a "concave" shape.

[0041] It should be further explained that the width of the guide rail 32 matches the diameter of the first guide wheel 62 , and the width and length of the guide groove 33 match the diameter and thickness of the second guide wheel 63 , respectively.

[0042] It is understandable that, with such a configuration, the first guide wheel 62 and the second guide wheel 63 will not swing due to the restrictions of the guide rail 32 and the guide groove 33 , thereby ensuring that the guide column 3 can stably guide the guide assembly 6 to move up and down along the opening 31 .

[0043] In order to keep the structure of the guide column 3 stable, in this embodiment, Figure 1 and Figure 2 The two guide columns 3 are symmetrically arranged on both sides of the base 2 , and the upper ends of the two guide columns 3 are fixed by a cross beam 35 .

[0044] It is understandable that, in such a configuration, the upper ends of the two guide columns 3 are fixed by the crossbeam 35, and the lower ends of the guide columns 3 are fixed to the ground, so that the guide columns 3 and the crossbeam 35 form a stable gantry structure, ensuring that the guide columns 3 can have a stable structure.

[0045] It needs to be further explained that a plurality of sensors 8 are arranged at intervals on the guide column 3 through the mounting rod 81, and the heights of the plurality of sensors 8 are different, so as to conveniently sense the lifting height of the lifting platform 1, so that the lifting motor 53 can accurately control the height of the lifting platform 1 moving up and down, and a plurality of height moving points can be set according to the plurality of sensors 8, so as to adapt to multi-layer laminated furnaces and laminated furnaces of different heights.

[0046] In order to stably support the lifting platform 1 during the lifting process, in this embodiment, reference Figures 1 to 3The fork arm 4 includes a first fork rod 41 and a second fork rod 42 which are arranged crosswise with each other. The upper end of the first fork rod 41 and the lower end of the second fork rod 42 are pivotally connected to the lifting platform 1 and the base 2 respectively. The connecting line between the pivot point of the first fork rod 41 and the lifting platform 1 and the pivot point of the second fork rod 42 and the base 2 are parallel to the guide column 3. The lower end of the first fork rod 41 is slidably connected to the first guide rail 21 on the base 2 through the first pulley 43, and the upper end of the second fork rod 42 is slidably connected to the second guide rail 11 on the lifting platform 1 through the second pulley 44.

[0047] It can be understood that, in such a configuration, the lifting platform 1 is supported by the cross-arranged first fork rod 41 and the second fork rod 42. During the lifting process of the lifting platform 1, the first pulley 43 of the first fork rod 41 and the second pulley 44 of the second fork rod 42 slide along the first guide rail 21 of the base 2 and the second guide rail 11 of the lifting platform 1 respectively, so that the fork arm 4 can adjust the supporting angle according to the height of the lifting platform 1 to ensure the parallelism of the lifting platform 1.

[0048] In order to prevent the lifting platform 1 from descending excessively, in this embodiment, reference Figures 1 to 3 The base 2 is provided with a plurality of support columns 22 at intervals, and the support columns 22 are arranged upward.

[0049] It is understandable that, in this arrangement, the four support columns 22 are used to support the lifting platform 1. After the lifting platform 1 descends to be supported by the four support columns 22, the lifting platform 1 cannot continue to descend, so that the lifting platform 1 descends to the lower limit position, thereby leaving space for the fork arm 4 to fold, thereby ensuring the safety of the fork arm 4.

[0050] In order to realize the product entering and exiting the furnace, in this embodiment, reference Figure 1 The traction device 7 includes a chain conveyor belt 71 and a traction motor 72. The chain conveyor belt 71 is arranged along the length direction of the lifting platform 1, and the traction motor 72 is connected to the chain conveyor belt 71 through a sprocket wheel 73.

[0051] It can be understood that, with such a configuration, when entering the furnace, the chain conveyor belt 71 is driven by the traction motor 72, and the chain conveyor belt 71 is combined with manpower or a push rod to push the product into the furnace. When taking the product out of the furnace, the product is pulled from the laminating furnace to the lifting platform 1 by manpower or a pull rod, and then driven out of the furnace by the chain conveyor belt 71.

[0052] The embodiment of the present application adopts a servo motor as the lifting motor 53, and the servo motor drives the lifting screw 52, ​​thereby driving the lifting platform 1 to move up and down along the guide column 3. Servo precision control is adopted to lift the product to a specified height and accurately dock with the tracks of different layers of the laminating furnace, so as to adapt to the multi-layer laminating furnace.

[0053] The above does not limit the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
