Description

Technical Field

[0001] This utility model relates to the field of C / C brake disc lifting fixture technology, and more specifically, to a fastening device for CC brake disc lifting fixture. Background Technology

[0002] The production process of C / C (carbon / carbon) composite brake discs requires at least three high-temperature treatments and approximately 1000 hours of vapor deposition (about 3-5 vapor deposition cycles). In actual production, the stacked carbon disc columns need to be repeatedly moved in and out of the deposition and high-temperature furnaces for deposition and graphitization. They also need to be hoisted to the inspection area for testing. With the continuous improvement of brake disc production technology, the loading capacity of the high-temperature treatment furnace and vapor deposition furnace is also increasing, from dozens of discs per furnace initially to hundreds, or even nearly a thousand discs now. The number of brake disc columns stacked in the furnace has also evolved from a single column to multiple columns (3-10), and the stacking height is also increasing, even exceeding 2 meters. With such a large loading capacity, on-site loading and unloading operations and transfers require a safe and reliable hoisting tool. Publication number CN207142648U relates to a hoisting tool for handling aircraft brake discs. Its unique feature is that it includes a brake disc placement box and a lifting handle mounted on top of it. The brake disc placement box includes a base plate, a positioning and lifting linkage mounted on the base plate, a fixing plate above the positioning and lifting linkage, and a sedimentation cylinder fitted onto the base plate. The lifting handle includes a pull ring and a lifting component connected together. This utility model enables multiple handling operations with a single stacking, reducing labor intensity and saving time. However, existing technologies have some problems: the existing hoisting fixtures have an upper pressure plate fastened to the upper edge of the deposition cylinder, which is only fixed by the lower boss of the upper pressure plate to prevent the hoisting rod from swaying. This hoisting device is only suitable for loading and transferring low-lying coal discs for inspection. If the coal discs are stacked too high, they will sway during hoisting. The lower boss of the upper pressure plate may damage or detach from the deposition cylinder. The hoisting rod may tilt, causing the coal disc to fall. The entire coal disc may detach from the hoisting rod and fall, damaging products and equipment, and even causing personal injury. Therefore, we propose a fastening device for CC brake disc hoisting fixtures. Utility Model Content

The slot allows for quick positioning of the deposition cylinder 2, facilitating its installation. The deposition cylinder 2 can be made of C / C or medium-coarse graphite. Multiple sets of different heights can be designed for the deposition cylinder 2. The height of the deposition cylinder 2 can be determined based on the height of the brake disc placed on the base plate 1, improving the applicability of the device.

[0025] Furthermore, a pressure plate 3 is movably connected to the deposition cylinder 2, and a rubber plate 7 is fixedly connected to the inner wall of the pressure plate 3. The rubber plate 7 is disposed between the deposition cylinder 2 and the pressure plate 3.

[0026] Specifically, a rubber plate 7 is provided at the contact part between the upper pressure plate 3 and the sedimentation cylinder 2, which can effectively buffer the shaking during hoisting, avoid damage to the sedimentation cylinder 2 or the upper pressure plate 3, extend their service life, and save resources.

[0027] Furthermore, a hanger rod 4 is detachably connected to the middle of the base plate 1, and a cross groove is opened in the middle of the base plate 1. A clamping plate 8 is fixedly connected to the other end of the hanger rod 4, and the clamping plate 8 is slidably connected in the cross groove.

[0028] Furthermore, a rotating groove is provided below the cross groove of the base plate 1, and the clamping plate 8 is rotatably connected in the rotating groove. A cross groove is provided on the inner wall of the rotating groove, and the clamping plate 8 is engaged in the cross groove.

[0029] Specifically, when installing the boom 4, the clamping plate 8 at the bottom of the boom 4 is inserted through the inner hole of the brake disc in the sedimentation cylinder 2 into the cross groove of the bottom plate 1, and moved along the cross groove to the rotating groove. The boom 4 is rotated forty-five degrees so that the clamping plate 8 on the boom 4 corresponds to the cross groove. At this time, the boom 4 is lifted upwards, and the clamping plate 8 will be engaged in the cross groove to complete the installation of the boom 4.

[0030] Furthermore, a lifting ring 5 is fixedly connected to one end of the boom 4. The lifting ring 5 is used to connect with a crane so that the device can be lifted by the crane and put into the high-temperature furnace to process the brake disc.

[0031] Furthermore, a fixing component 6 is provided on the lifting rod 4. The fixing component 6 is used to fix the pressure plate 3. The fixing component 6 includes a clamping nut 61. The lifting rod 4 is provided with threads, and the clamping nut 61 is threadedly connected to the lifting rod 4.

[0032] Specifically, handles 62 are fixedly connected to both sides of the clamping nut 61, and the handles 62 are used to drive the clamping nut 61 to rotate.

[0034] Specifically, when installing the pressure plate 3, the clearance opening on the pressure plate 3 is aligned with the lifting rod 4, and the pressure plate 3 is inserted into the lifting rod 4 along the clearance opening. Then, the pressure plate 3 is snapped onto the sedimentation cylinder 2. Then, the clamping nut 61 is rotated by turning the handle 62, so that the clamping nut 61 is fixed in the conical groove of the pressure plate 3. While fixing the pressure plate 3, the lifting rod 4 is also prevented from shaking, thereby improving the stability of the device.

[0035] The workflow of this utility model is as follows: When it is necessary to hoist the device into the furnace, the brake disc is placed on the base plate 1 at the work site, and the deposition cylinder 2 is inserted. The work vehicle is transported to the furnace site. The lower clamping plate 8 of the hoisting rod 4 is inserted into the cross groove of the base plate 1 along the inner hole of the brake disc and finally moved to the rotating groove. The lower clamping plate 8 is inserted into the cross groove of the base plate 1 and the hoisting rod 4 is fixed. The radial opening of the upper pressure plate 3 is inserted into the hoisting rod 4 so that its inner edge is inserted into the deposition cylinder 2. The handle 62 is turned and the clamping nut 61 is tightened to fix the hoisting rod 4 and prevent it from shaking.

The lower clamping plate 8 is then inserted into the cross groove of the bottom plate 1 and the lifting rod 4 is fixed. The radial opening of the upper pressure plate 3 is inserted into the lifting rod 4 so that its inner edge is inserted into the sedimentation cylinder 2. The handle 62 is turned and the clamping nut 61 is tightened to fix the lifting rod 4 and prevent it from shaking. The crane can lift the device out of the furnace through the lifting rod 4 and the lifting ring 5 and place it on the work car. Then the hook is removed, the clamping nut 61 is loosened by the handle 62, the pressure plate 3 is removed, the lifting rod 4 is rotated, the clamping plate 8 is disengaged from the cross groove of the bottom plate 1, the lifting rod 4 is taken out, and it is transported to the work site for carbon tray cleaning, weighing and other operations.

[0037] The aforementioned fastening device for lifting CC brake discs involves sequentially stacking the brake discs onto a base plate 1. Based on the stacking height, the discs can be sequentially inserted into sedimentation cylinders 2. After stacking, the lifting rod 4 is inserted into the cross groove of the base plate 1 from the top along the inner hole of the brake disc and rotated into the rotating groove, causing the clamping plate 8 on the lifting rod 4 to fully engage with the cross groove at the bottom of the base plate 1.
