Description

Technical Field

[0001] This utility model relates to the technical field of pressure resistance testing devices, and in particular to an ultra-large-sized planar target loading furnace lifting vehicle. Background Technology

[0002] As the size of ITO planar targets increases, the weight of a single target also increases. Currently, companies manually load and unload the targets. However, with the increasing weight of the targets, large-sized targets may crack due to slight bending during loading and unloading. Therefore, a large-sized target loading and unloading elevator is needed for assistance.

[0003] In the prior art, such as the patent with publication number CN209223341U, a heating platform for bonding planar target materials is disclosed, including a base, a support platform, a lifting mechanism, a heating plate, a thermally conductive graphite plate, an aluminum alloy thermally conductive plate, a heat insulation cover, a control panel, casters, and an ultrasonic transducer. The lifting mechanism is provided on the base, and the lifting mechanism includes a hydraulic cylinder and a piston rod. Two hydraulic cylinders are provided on the base, and the piston rod inside the hydraulic cylinder is arranged facing upward. The upper end of the piston rod is connected to the support platform. The ultrasonic transducer is provided at the bottom of the support platform, and the heating plate is provided above the support platform. Heating tubes are evenly distributed on the heating plate.

[0004] The above structure uses a lifting mechanism and a heating plate to transfer the target material. However, when loading and unloading large-sized target materials, the planar target material may be slightly bent and cracked due to the gap between the platform and the sintering furnace during the transfer process, whether it is a raw target material or a sintered target material. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose an ultra-large-sized planar target loading furnace lifting vehicle to solve the problem that the planar target material will slightly bend and crack due to the gap between the platform and the sintering furnace bearing layer.

[0006] To achieve the above objectives, this utility model provides an ultra-large-sized planar target loading furnace lifting vehicle, including a lifting platform for carrying planar target materials, a movable wheel frame at the bottom of the lifting platform, and a lifting mechanism between the lifting platform and the movable wheel frame.

[0007] The lifting platform has sliding grooves on both sides, and two sets of positioning plates are slidably installed in the sliding grooves. Slide rails are fixedly installed on the two sets of positioning plates, and extension plates are fixedly installed on the top of the slide rails. Arc grooves are opened on one side of the positioning plates and extension plates.

[0008] Multiple sets of rubber roller seats are fixedly installed on the top of the extension plate and the lifting platform. The rubber roller seats are distributed in a rectangular array on the lifting platform, and the inside of the rubber roller seats is provided with spheres.

[0009] Preferably, the bottom sides of the lifting platform are provided with locking holes at equal intervals, the locking holes penetrate the slide groove and the positioning plate, and the internal threads of the locking holes are connected to limit posts.

[0010] Preferably, multiple sets of top rods are fixedly installed around the top of the movable wheel frame, and pads corresponding to the top rods are fixedly installed at the bottom of the lifting platform.

[0011] Preferably, the top height of the lifting platform is flush with the top height of the extension plate, and the ends of the arc grooves opened in the extension plate are all chamfered.

[0012] Preferably, at least four sets of top rods are provided, and the top end of the top rod is provided with rubber.

[0013] Preferably, the lifting mechanism includes a hydraulic cylinder fixedly mounted on a movable wheel frame, the output end of the hydraulic cylinder being fixedly connected to the bottom end of the lifting platform, and a first lifting rod and a second lifting rod being movably mounted on the movable wheel frame. The first lifting rod and the second lifting rod are distributed on both sides of the hydraulic cylinder, and the top ends of the first lifting rod and the second lifting rod are movably connected to the bottom of the lifting platform.

[0014] Preferably, both the first lifting rod and the second lifting rod include connecting rods, and both the first lifting rod and the second lifting rod are formed by two sets of connecting rods hinged together. The first lifting rod and the second lifting rod are arranged in a mirror symmetrical manner with respect to the center of the hydraulic cylinder.

[0015] The beneficial effects of this utility model are: placing a large-size flat target on the lifting platform so that the large-size flat target is located on the ball inside the rubber roller seat, and then driving the lifting platform to rise through the hydraulic cylinder in the lifting mechanism, raising the target to a height parallel to the sintering furnace support layer.

[0016] Based on the distance between the lifting platform and the sintering furnace, the positioning plate and the extension plate are extended by means of a slide rail. The arc grooves in the two sets of extension plates contact the outside of the sintering furnace. During the process of pushing the target material from the lifting platform to the sintering furnace bearing layer, the target material is pushed slowly onto the sintering furnace bearing layer along the rubber roller seat at the top of the extension plate and the lifting platform under the action of the ball. This avoids the situation of cracking due to slight bending when loading and unloading large-sized target materials. The loading and unloading process is more stable and greatly improves the yield of target materials. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an ultra-large planar target loading furnace lifting vehicle includes a lifting platform 1 for carrying planar target materials, a movable wheel frame 2 is provided at the bottom of the lifting platform 1, and a lifting mechanism is provided between the lifting platform 1 and the movable wheel frame 2.

[0025] The lifting platform 1 has sliding grooves 7 on both sides. Two sets of positioning plates 8 are slidably installed in the sliding grooves 7. Slide rails 9 are fixedly installed on the two sets of positioning plates 8. An extension plate 10 is fixedly installed on the top of the slide rails 9. An arc groove 13 is opened on one side of both the positioning plate 8 and the extension plate 10.

[0026] Multiple sets of rubber roller seats 11 are fixedly installed on the top of both the extension plate 10 and the lifting platform 1. The rubber roller seats 11 are arranged in a rectangular array on the lifting platform 1, and a ball 12 is provided inside the rubber roller seat 11.

[0027] In this embodiment, a large-size planar target is placed on the lifting platform 1, so that the large-size planar target is located on the ball 12 inside the rubber roller seat 11. Then, the lifting platform 1 is raised by the hydraulic cylinder 3 in the lifting mechanism, so that the lifting platform 1 of the target is raised to a height parallel to the sintering layer of the sintering furnace.

[0028] Based on the distance between the lifting platform 1 and the sintering furnace, the positioning plate 8 and the extension plate 10 are extended by the slide rail 9. The arc grooves 13 in the two sets of extension plates 10 contact the outside of the sintering furnace. During the process of pushing the target material from the lifting platform 1 to the sintering furnace bearing layer, the target material is pushed slowly onto the sintering furnace bearing layer by the rubber roller seat 11 at the top of the extension plate 10 and the lifting platform 1 under the action of the ball 12. This avoids the situation of cracking due to slight bending when loading and unloading large-sized target materials. The loading and unloading process is more stable and greatly improves the yield of target materials.

[0029] As one implementation method, such as Figure 1 , Figure 2 and Figure 3 As shown, the bottom of the lifting platform 1 has equidistant locking holes 14 on both sides. The locking holes 14 pass through the slide groove 7 and the positioning plate 8, and the internal threads of the locking holes 14 are connected to limit posts 15.

[0030] In this embodiment, the distance between the two sets of positioning plates 8 is adjusted according to different sintering furnaces. At the same time, the positioning plate 8 and the extension plate 10 are extended by the slide rail 9. The arc groove 13 in the two sets of extension plates 10 contacts the outside of the sintering furnace. The limiting column 15 passes through the locking hole 14 in the lifting platform 1 and the positioning plate 8 to complete the locking, thereby improving the stability during loading and unloading.

[0031] As one implementation method, such as Figure 1 , Figure 2 As shown, multiple sets of top rods 17 are fixedly installed around the top of the movable wheel frame 2, and pads 16 corresponding to the top rods 17 are fixedly installed at the bottom of the lifting platform 1.

[0032] The top rod 17 is provided with at least four sets, and the top of the top rod 17 is provided with rubber.

[0033] In this embodiment, when the lifting platform 1 is lowered to its lowest height, the pad 16 at the bottom of the lifting platform 1 abuts against the top rod 17 at the top of the moving wheel frame 2 to prevent the lifting platform 1 from accidentally touching the minimum limit of the hydraulic cylinder 3 when it is lowered.

[0034] As one implementation method, such as Figure 1 , Figure 3 As shown, the top height of the lifting platform 1 is flush with the top height of the extension plate 10, and the ends of the arc grooves 13 opened in the extension plate 10 are all chamfered.

[0035] In this embodiment, during the process of pushing the target material from the lifting platform 1 to the sintering furnace support layer, the target material is pushed slowly onto the sintering furnace support layer by the rubber roller seat 11 at the top of the extension plate 10 and the lifting platform 1 under the action of the ball 12. The end of the extension plate 10 is chamfered to avoid rubbing against the sintering furnace.

[0036] As one implementation method, such as Figure 1 , Figure 2 As shown, the lifting mechanism includes a hydraulic cylinder 3 fixedly installed on the movable wheel frame 2. The output end of the hydraulic cylinder 3 is fixedly connected to the bottom end of the lifting platform 1. A first lifting rod 4 and a second lifting rod 5 are also movably installed on the movable wheel frame 2. The first lifting rod 4 and the second lifting rod 5 are distributed on both sides of the hydraulic cylinder 3, and the top ends of the first lifting rod 4 and the second lifting rod 5 are movably connected to the bottom of the lifting platform 1.

[0037] In this embodiment, a large-size planar target is placed on the lifting platform 1, so that the large-size planar target is located on the ball 12 inside the rubber roller seat 11. Then, the lifting platform 1 is driven to rise by the hydraulic cylinder 3. The first lifting rod 4 and the second lifting rod 5 simultaneously deform and support the target, raising the lifting platform 1 to a height parallel to the sintering furnace support layer.

[0038] As one implementation method, such as Figure 1 , Figure 2 As shown, both the first lifting rod 4 and the second lifting rod 5 include connecting rods 6. The first lifting rod 4 and the second lifting rod 5 are both formed by two sets of connecting rods 6 hinged to each other, and the first lifting rod 4 and the second lifting rod 5 are arranged in a mirror symmetrical manner with respect to the center of the hydraulic cylinder 3.

[0039] In this embodiment, the first lifting rod 4 and the second lifting rod 5 provide support when the lifting platform 1 is raised or lowered via the hinged connecting rod 6, resulting in strong load-bearing capacity and stability.

[0040] Working principle: During use, a large-size flat target is placed on the lifting platform 1, so that the large-size flat target is located on the ball 12 inside the rubber roller seat 11. Then, the hydraulic cylinder 3 in the lifting mechanism drives the lifting platform 1 to rise. The first lifting rod 4 and the second lifting rod 5 simultaneously deform and support, raising the lifting platform 1 of the target to a height parallel to the sintering layer of the sintering furnace. According to the distance between the lifting platform 1 and the sintering furnace, the positioning plate 8 and the extension plate 10 are extended by the slide rail 9. The arc groove 13 in the two sets of extension plates 10 contacts the outside of the sintering furnace. The locking is completed by the limiting column 15 passing through the locking hole 14 in the lifting platform 1 and the positioning plate 8.

[0041] During the process of pushing the target material from the lifting platform 1 to the sintering furnace support layer, the target material is pushed slowly onto the sintering furnace support layer by the rubber roller seat 11 at the top of the extension plate 10 and the lifting platform 1 under the action of the ball 12.

[0042] After the target material is sintered, the lifting platform 1 is raised to a height parallel to the sintering layer of the sintering furnace, and the target material is slowly pushed onto the flat target material loading lifting car. Finally, the extension plate 10 with rubber roller seat 11 and ball 12 and the positioning plate 8 are disassembled and placed on the moving wheel frame 2.
