Description

Technical Field

[0001] The invention relates to the technical field of automobile component casting and processing, in particular to a transport sling for automobile component casting. Background Art

[0002] During the casting process of automotive parts, it is necessary to use a handling hoist to lift the smelting tube used for casting smelting. The main function of the smelting tube is to heat the metal raw materials (such as iron, aluminum, copper, etc.) to a molten state to form liquid metal that meets the casting requirements. During this process, the high temperature environment inside the smelting tube allows the metal raw materials to be fully melted and reach the required temperature and composition requirements.

[0003] In the process of lifting and moving the smelting tube by using a handling hoist, in order to facilitate the dumping operation of the smelting tube after lifting, the smelting tube is rotatably connected to the hoist. However, due to the rotatability of the smelting tube, the smelting tube is easily subjected to force and swings at one end during the process of lifting the smelting tube by using the hoist, causing the melted raw materials inside the smelting tube to spill and increasing the risk during the lifting process. For this reason, we propose a handling hoist for casting automotive parts. Summary of the invention

[0034] Preferably, the pulling assembly includes a fixing frame 901 fixed to the lower end of the rotating plate 2, a first winding wheel 902 is rotatably connected to the fixing frame 901, a first pull rope 903 is wound on the first winding wheel 902, one end of the first pull rope 903 is fixed to the lower side of the outer side of the smelting cylinder 103, and a supporting assembly for supporting the first pull rope 903 is provided on the two sets of mounting plates 4;

[0035] It should be noted here that: through transmission, the first winding wheel 902 on the fixed frame 901 is driven to rotate. During the rotation of the first winding wheel 902, the first winding wheel 902 reels in the first pull rope 903 and the support rod 1002 on the support assembly supports the first pull rope 903 after being stressed, thereby forming a pulling effect on the smelting tube 103. At this time, the rotation restriction on the smelting tube 103 is released. By pulling the smelting tube 103, the smelting tube 103 is tilted due to the force, thereby achieving the effect of tipping the smelting tube 103.

[0036] Preferably, the support assembly includes a side plate 1001 fixed to one side of the two sets of mounting plates 4, and a support rod 1002 for supporting the inner side of the first pull rope 903 is rotatably connected between the two sets of side plates 1001;

[0039] It should be noted here that: the operating shaft 1203 is driven to rotate by the first motor 1207, and during the rotation of the operating shaft 1203, the second winding wheel 1204 is driven to rotate. During the rotation of the second winding wheel 1204, the second winding wheel 1204 reels in the second pull rope 1205 and the auxiliary support of the second winding wheel 1204 by the auxiliary rod 1206 and the connecting rod 1202 during the winding process, the slide plate 703 is pulled. Through the pulling action, the pin 704 on the slide plate 703 slides out of the limiting hole 702 of the limiting plate 701, and at this time contacts the rotatable limit of the mounting shaft 501 and the smelting cylinder 103.

[0040] Preferably, the transmission assembly includes a spline sleeve 1301 rotating between the operating shaft 1203 and one end of the first winding wheel 902, and the two sets of spline sleeves 1301 are connected and transmitted through the spline shaft 1302;

[0041] It should be noted here that: during the rotation of the operating shaft 1203 , the first winding wheel 902 on the fixed frame 901 is driven to rotate through the connection and transmission between the spline shaft 1302 and the two sets of spline sleeves 1301 .

[0042] Preferably, the connecting assembly includes a connecting seat 801 fixed on one side of the mounting plate 4, a plurality of groups of slide bars 802 are fixed on the connecting seat 801, a sleeve 803 is slidably connected to the slide bar 802, one end of the sleeve 803 is fixed to the slide plate 703, and a spring 804 is sleeved on the outer side of each group of sleeves 803, and the two ends of the spring 804 are respectively connected to the connecting seat 801 and the slide plate 703;

[0043] It should be noted here that: by connecting the slide bar 802 and the sleeve 803 on the seat 801, the sliding guide movement of the auxiliary slide plate 703 after being stressed is facilitated, and by each group of springs 804, the return movement of the slide plate 703 after movement is facilitated.

[0044] Preferably, the rotating assembly includes a rotating seat 301 fixed to the upper end of the rotating plate 2, and a second motor 302 for rotating the rotating seat 301 is installed on the hanging plate 101;

[0045] It should be noted here that: the second motor 302 drives the rotating seat 301 and the rotating plate 2 on the rotating seat 301 to rotate, and the rotation of the rotating plate 2 drives the installed smelting cylinder 103 to rotate, so that the smelting cylinder 103 can pour the solution at different angles.

[0046] Preferably, the driving assembly includes two groups of L-shaped frames 601 fixed to the lower end of the rotating plate 2, a double-headed screw 602 is rotatably connected between the two groups of L-shaped frames 601, threaded sleeves 603 are fixed on the two groups of mounting plates 4, and the two groups of threaded sleeves 603 are respectively meshed with the two ends of the double-headed screw 602, and a third motor 604 for driving the double-headed screw 602 is installed on the L-shaped frame 601, and multiple groups of guide rods 605 are slidably connected to the two groups of mounting plates 4, and the guide rods 605 are fixed between the two groups of L-shaped frames 601; the threads at the two ends of the double-headed screw 602 are arranged in opposite directions;

[0047] It should be noted here that: the double-headed screw 602 is driven to rotate by the third motor 604. Since the threads at both ends of the double-headed screw 602 are arranged in opposite directions, during the rotation of the double-headed screw 602, the two sets of threaded sleeves 603 are respectively engaged with the two ends of the double-headed screw 602 to drive the two sets of mounting plates 4 to move under force. During the movement of the two sets of mounting plates 4, the sliding guiding effect of each set of guide rods 605 on the mounting plates 4 causes the two sets of mounting plates 4 to move closer to or away from each other after being subjected to force, thereby adjusting the spacing between the two sets of mounting plates 4.

[0048] In this scheme: a handling sling for casting automobile parts, comprising the following steps:

[0049] During the casting of automobile parts, when a handling sling is used to assist in the handling of the smelting barrel 103 carrying the molten raw materials, the hanging plate 101 is moved to the top of the smelting barrel 103 by the sling 102. After the movement is completed, the distance between the two groups of mounting plates 4 is adjusted by the driving component to facilitate the installation and connection between the two groups of mounting plates 4 and the two sides of the smelting barrel 103. After the distance between the two groups of mounting plates 4 is adjusted, the mounting plate 503 on the outer fixing rod 502 of the smelting barrel 103 and the mounting plate 503 on the mounting shaft 501 are installed by bolts to complete the connection between the smelting barrel 103 and the sling;

[0050] After the smelting tube 103 is installed and connected, the smelting tube 103 is driven to be lifted and moved through the driving action of the sling 102 and the connection action of the hanging plate 101, the rotating plate 2 and the two groups of mounting plates 4. In the process of lifting and moving the smelting tube 103, the elastic force of the springs 804 of the connecting assembly on the slide plate 703 is pushed, so that the latch 704 on the slide plate 703 is inserted into the limiting hole 702 of the limiting plate 701. The insertion and limiting action of the latch 704 and the limiting hole 702 limits the swing of the mounting shaft 501 and the smelting tube 103 after one end of the mounting shaft 501 is installed, so as to prevent the smelting tube 103 from swinging due to the force during the lifting and moving process, which affects the safety of the smelting tube 103 during the lifting and moving process.

[0051] After the smelting tube 103 is hoisted to the specified position, the operating shaft 1203 is driven to rotate by the first motor 1207. During the rotation of the operating shaft 1203, the second winding wheel 1204 is driven to rotate. During the rotation of the second winding wheel 1204, the second winding wheel 1204 reels the second pull rope 1205 and the auxiliary rod 1206 and the connecting rod 1202 assist in supporting the second winding wheel 1204 during the reeling process, thereby pulling the slide plate 703. Through the pulling action, the latch 704 on the slide plate 703 slides out of the limiting hole 702 of the limiting plate 701. At this time, the contact with the mounting shaft 501 and the smelting tube 1 03 is rotatable limited, and during the rotation of the operating shaft 1203, the connection transmission effect between the spline shaft 1302 and the two sets of spline sleeves 1301 drives the first winding wheel 902 on the fixed frame 901 to rotate. During the rotation of the first winding wheel 902, the winding effect of the first winding wheel 902 on the first pull rope 903 and the supporting effect of the support rod 1002 on the support assembly on the first pull rope 903 after being stressed, a pulling effect is formed on the smelting cylinder 103, so that the rotation restriction on the smelting cylinder 103 is released at this time, and the smelting cylinder 103 is pulled, so that the smelting cylinder 103 is tilted due to the force, thereby achieving the effect of tipping the smelting cylinder 103.
