Description

Technical Field

[0001] The invention relates to the technical field of hanging devices, in particular to a bearing steel quenched and tempered rapid transportation hanging device. Background Art

[0002] Quenching is a metal heat treatment process for bearing steel tempering and rapid transport hanging device. It is a heat treatment process in which the metal workpiece is heated to a certain temperature, kept warm for a period of time, and then quickly immersed in a cooling medium for rapid cooling. Its purpose is to improve the metal's hardness, strength, wear resistance and other mechanical properties. The metal's organizational structure is changed through quenching, thereby significantly improving the metal's performance. The principle is to quickly heat the metal workpiece to a certain temperature and keep it warm to transform the metal's internal organization into austenite, and then quickly immerse it in a quenching medium for rapid cooling to obtain strengthening phase organizations such as martensite or bainite.

[0003] During quenching, the metal workpiece is first transported into the heating furnace by a transport vehicle for heating, and is heated to the required quenching temperature, which is usually a temperature above the melting point of the metal. Before quenching, the heated metal workpiece is lifted by the driving assembly and transported to the quenching pool, and the quenching basket is completely placed in the quenching medium to allow the metal workpiece to cool rapidly. During the cooling process, the quenching basket needs to be controlled to move up and down by the boom, which can accelerate the flow of the quenching medium and ensure the quenching effect. In some prior arts, the boom is controlled to move horizontally to the top of the quenching basket, and a protruding triangular block is provided on the inner side of the bottom end of the boom. At this time, the height of the block is lower than the height of the top of the quenching basket. Therefore, the horizontal movement of the boom is not affected by the block. Both ends of the quenching basket are provided with protruding slots that are compatible with the triangular blocks of the boom. When the boom moves vertically upward, the triangular blocks cooperate with the slots to lift the quenching basket. However, this method only lifts the quenching basket, and there is no limiting measure on the top. Moreover, the cooperation between the triangular blocks and the slots has limited limiting effect on the quenching basket. During the hanging and moving process, the quenching basket may shake and be difficult to maintain stability, which poses certain risks. Moreover, when moving up and down in the quenching pool, if the boom moves too fast, the moving speeds of the boom and the quenching basket may be inconsistent, which may cause the quenching basket to fall off the boom.

[0004] Therefore, the present invention provides a bearing steel quenched and tempered rapid transportation hanging device. Summary of the invention

[0019] Beneficial effects of the present invention:

[0020] (1) The present invention discloses a bearing steel tempering rapid transportation hanging device, which controls the driving assembly to move the connecting arm to the position of the quenching basket. When the quenching basket is lifted, the deadweight of the quenching basket squeezes the adjusting column so that the telescopic block of the adjusting assembly is inserted into the first slot on the side wall of the quenching basket.

[0021] (2) The invention discloses a bearing steel tempering rapid transport hanging device. When the quenching basket is hoisted, the solenoid valve switch is triggered, causing the movable block to extend the connecting arm. When the quenching basket moves up and down in the quenching pool, the movable block limits the moving range of the quenching basket from the top of the quenching basket. While accelerating the flow of the quenching medium and ensuring the quenching effect, the movable block cooperates with the guide block to limit the quenching basket, so that the quenching basket can still be smoothly lifted after the metal workpiece is quenched.

[0022] (3) In the bearing steel tempering rapid transportation hanging device described in the present invention, when the connecting arm is lifted to lift the quenching basket, the guide block on the top of the connecting seat cooperates with the guide groove on the quenching basket fixing plate, and the inclined surfaces of the two cooperate with each other, so that the quenching basket can be automatically corrected before being lifted, avoiding a slight deviation in the position of the quenching basket and the connecting arm, which causes the telescopic block to be unable to be inserted into the first slot and the quenching basket to be unable to maintain stability.

DETAILED DESCRIPTION

[0035] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0036] Example: Figure 1-Figure 10 As shown, a bearing steel quenched and tempered rapid transportation hanging device described in the present invention comprises a bridge frame 1 and a frame 2, a first guide rail 11 is installed on the top of the bridge frame 1, a quenching basket 3 is placed under the bridge frame 1, the first guide rail 11 is slidably connected to the frame 2, a driving assembly 4 is arranged on the top of the frame 2, the driving assembly 4 comprises a moving frame 41 slidably connected to the frame 2, a winch 43 is fixedly installed on the top of the moving frame 41, the winch 43 is fixedly connected to a steel wire rope 44, an end of the steel wire rope 44 away from the winch 43 is fixedly connected to a movable frame 45, both sides of the lower end of the movable frame 45 are respectively fixedly connected to connecting arms 46, opposite sides of the lower end of the connecting arms 46 are respectively provided with adjusting assemblies 5, the adjusting assembly 5 comprises a group of connecting seats 51 fixedly connected to opposite sides of the lower end of the connecting arms 46, and the connecting seats 51 are slidably connected to the connecting arms 46. A group of adjusting columns 52 are connected, and a group of telescopic blocks 53 are slidably connected to one side of the connecting seat 51 close to the quenching basket 3. A limiting assembly 6 is arranged on the top of the connecting seat 51, and the limiting assembly 6 includes a movable block 64 slidably connected to the connecting arm 46 and a guide block 61 fixedly connected to the top of the connecting seat 51; the quenching basket 3 is equipped to load the heated metal workpiece, and is lifted and transported by cooperating with the driving assembly 4 and the adjusting assembly 5; the adjusting assembly 5 is equipped to limit the position of the quenching basket 3 by its own weight when lifting the quenching basket 3, so as to avoid the quenching basket 3 from shaking during the lifting and transportation process; the limiting assembly 6 is equipped to limit the movable range of the quenching basket 3 during the quenching process, so as to ensure the quenching effect while preventing the quenching basket 3 from falling off the adjusting assembly 5.

[0037] In this embodiment, after the metal workpiece is heated in the heating furnace, the quenching basket 3 loaded with the metal workpiece is placed in a fixed position, and the driving assembly 4 is controlled to move above the quenching basket 3. The height of the connecting seat 51 at the bottom end of the connecting arm 46 is lower than the height of the fixed plate 31 of the quenching basket 3. Therefore, when the connecting arm 46 follows the movement, the adjusting assembly 5 can move to the bottom of the fixed plate 31. When the connecting arm 46 is controlled to move up again, the bottom of the fixed plate 31 on both sides of the quenching basket 3 abuts against the adjusting assembly 5, so that the adjusting column 52 is squeezed into the connecting seat 51, and the connecting plate 54 moves downward in the connecting seat 51. The lower end of the adjusting column 52 protrudes out of the connecting seat 51. When the adjusting column 52 is squeezed and moved downward, it drives the telescopic block 53 to move out of the connecting seat 51 and engages with the first slot 33 of the quenching basket 3. There is a group of telescopic blocks 53 on both sides of the basket 3 to limit the quenching basket 3 so that it can maintain a stable state during the hanging and moving process. At the same time, before the quenching basket 3 is lifted, the guide block 61 cooperates with the guide groove 62 to automatically correct the position of the quenching basket 3 to avoid a slight deviation in the position between the quenching basket 3 and the connecting arm 46, which causes the telescopic block 53 to be unable to engage with the first slot 33. When the bottom of the fixed plate 31 abuts against the connecting seat 51, the movable block 64 is triggered to extend. When the quenching basket 3 moves up and down in the quenching pool driven by the driving assembly 4, the movable range of the quenching basket 3 itself is limited so that it can only move within the range between the connecting seat 51 and the movable block 64, so as to avoid the quenching basket 3 from falling off, so that the connecting arm 46 can drive the quenching basket 3 to move up again after quenching is completed.

[0038] like Figure 1-Figure 4 As shown, a second guide rail 21 is installed on the top of the frame 2, and the second guide rail 21 is slidably connected to the movable frame 41, and the frame 2 and the movable frame 41 are both connected to a driving motor; a fixed plate 31 is fixedly connected to the opposite side of the quenching basket 3, and a connecting block 32 is fixedly connected to the bottom of the end of the fixed plate 31 close to the quenching basket 3, and the connecting block 32 is fixedly connected to the side wall of the quenching basket 3, and a group of first card grooves 33 are opened on the side of the connecting block 32 away from the quenching basket 3; the driving assembly 4 also includes a fixed arm 42 fixedly connected to the two sides of the bottom of the movable frame 41, and a third guide rail 421 is installed on the opposite side of the fixed arm 42, and the movable frame 45 is slidably engaged with the third guide rail 421.

[0039] In this embodiment, starting the motor of the frame 2 allows the frame 2 to move together with the driving component 4 on the first guide rail 11. After the motor of the mobile frame 41 is started, the mobile frame 41 can be controlled to move on the second guide rail 21, both of which are used to adjust the position of the connecting arm 46. The winch 43 is used to control the height of the movable frame 45 through the wire rope 44. By winding or loosening the wire rope 44, the movable frame 45 slides on the third guide rail 421 of the fixed arm 42, thereby achieving the effect of controlling the height of the connecting arm 46. The adjusting component 5 at the lower end of the connecting arm 46 cooperates with the two sides of the quenching basket 3 to realize the lifting of the quenching basket 3.

[0040] like Figure 4-Figure 9 As shown, the adjustment component 5 also includes a group of limiting grooves 511 opened on the side of the connecting seat 51 close to the connecting block 32, the limiting grooves 511 are slidably connected to the telescopic block 53, the top of the end of the telescopic block 53 away from the connecting block 32 is set as an inclined surface, and the lower end of the inclined surface of the telescopic block 53 is fixedly connected with a clamping block 531, and a second clamping groove 521 is opened on the side of the adjustment column 52 close to the connecting block 32, and the second clamping groove 521 is adapted to the telescopic block 53, and the end of the telescopic block 53 away from the second clamping groove 521 is connected to the first clamping groove 33 cooperates with each other, a second sliding groove 522 is opened on the inclined surface of the second slot 521, and the clamping block 531 is slidably engaged with the second sliding groove 522; the connecting seat 51 is hollow, and first sliding grooves 512 are respectively opened at both ends of the inner wall of the connecting seat 51, and a connecting plate 54 is fixedly connected to the upper end of the adjusting column 52, and both ends of the connecting plate 54 are slidably engaged with the first sliding groove 512, and a group of springs 55 are fixedly connected to the bottom of the inner wall of the connecting seat 51, and one end of the spring 55 away from the connecting plate 54 is fixedly connected to the bottom of the inner wall of the connecting seat 51.

[0041] In this embodiment, when the connecting arm 46 drives the adjustment component 5 to move upward, the bottom of the fixed plate 31 abuts against the top of the adjustment column 52, so that the adjustment column 52 is squeezed and moved downward, and the connecting plate 54 fixedly connected to the adjustment column 52 slides downward in the connecting seat 51, so that the spring 55 at the bottom of the connecting plate 54 is compressed. In the initial state, the upper end of the adjustment column 52 protrudes from the connecting seat 51, and its lower end is flush with the bottom of the connecting seat 51. When the adjustment column 52 is squeezed and moved downward, its upper end is flush with the top of the connecting seat 51, and its lower end protrudes from the connecting seat 51. The position where the adjustment column 52 passes through the side wall of the connecting seat 51 is provided with a sealing The quenching medium is prevented from entering the cavity of the connecting seat 51 when the connecting arm 46 drives the quenching basket 3 to enter the quenching pool. The clamping block 531 on the telescopic block 53 is located at the lower end of the inclined surface. The telescopic block 53 is restricted by the limiting groove 511. When the adjusting column 52 moves downward, the clamping block 531 of the telescopic block 53 is driven to slide upward in the second slide groove 522, so that the telescopic block 53 slides out of the connecting seat 51 under the restriction of the limiting groove 511 and is clamped in the first clamping groove 33. There is a group of parallel telescopic blocks 53 on both sides of the quenching basket 3 to restrict it, so that the quenching basket 3 can remain stable during the hanging process.

[0042] like Figure 5-Figure 10As shown, the limit assembly 6 also includes a solenoid valve 63 installed on the top of the connecting seat 51, the movable block 64 is electrically connected to the solenoid valve 63, and the solenoid valve 63 cooperates with the fixed plate 31; the opposite side of the top of the guide block 61 is provided with an inclined surface, and the end of the fixed plate 31 away from the quenching basket 3 is provided with a guide groove 62, and the two sides of the lower end of the guide groove 62 are provided with inclined surfaces, and the inclined surface of the guide groove 62 cooperates with the inclined surface of the top of the guide block 61, and the guide groove 62 is slidably connected to the guide block 61; the movable block 64 is located at the top of the guide block 61, and the distance between the movable block 64 and the top of the connecting seat 51 is greater than the thickness of the fixed plate 31; the connection between the connecting arm 46 and the movable block 64, and the connection between the connecting seat 51 and the adjusting column 52 and the telescopic block 53 are respectively provided with sealing members.

[0043] In the present embodiment, when the fixing plate 31 abuts against the top of the connecting seat 51, the fixing plate 31 presses the solenoid valve 63 on the top of the connecting seat 51, triggering the switch so that the movable block 64 extends out from the connecting arm 46. When the connecting arm 46 drives the hoisted quenching basket 3 to enter the quenching pool and move up and down quickly, the falling speed of the connecting arm 46 and the quenching basket 3 may be inconsistent. At this time, the fixing plate 31 will be separated from the connecting seat 51. The function of the movable block 64 is to limit the range of movement of the quenching basket 3 itself, so that it can only move within the range between the connecting seat 51 and the movable block 64, and is also limited by the guide block 61 when it moves. When the quenching basket 3 abuts against the top of the connecting seat 51 again, the connection between the telescopic block 53 and the first slot 33 is not affected, thereby avoiding the deviation of the position of the quenching basket 3, which causes the telescopic block 53 to be unable to engage with the first slot 33.

[0044] Working principle: When in use, the quenching basket 3 is placed in a fixed position, the driving motor of the driving assembly 4 is started, and the control frame 2 drives the driving assembly 4 to move on the first guide rail 11. At this time, the horizontal height of the lower end of the connecting arm 46 is lower than the bottom height of the fixed plate 31 of the quenching basket 3. When the driving assembly 4 reaches the top of the quenching basket 3, the connecting seat 51 is located below the fixed plate 31, and the control winch 43 pulls the wire rope 44 to drive the connecting arm 46 to move upward. The top of the guide block 61 first contacts the fixed plate 31. Under the mutual cooperation of the inclined surface of the guide block 61 and the inclined surface of the guide groove 62, the guide block 61 is engaged with the guide groove 62, so that The quenching basket 3 can automatically correct its deviation before being fully hoisted, so as to avoid a slight deviation between the position of the quenching basket 3 and the connecting arm 46, which may cause the telescopic block 53 to be unable to engage with the first card slot 33. When the adjusting column 52 abuts against the fixing plate 31, the adjusting column 52 is gradually squeezed into the connecting seat 51, and the adjusting column 52 moves downward. At the same time, the spring 55 is compressed. When the adjusting column 52 moves downward, the card block 531 of the telescopic block 53 slides upward in the second slide slot 522, so that the telescopic block 53 extends from the connecting seat 51 and is engaged in the first card slot 33, so as to limit the quenching basket 3 and keep it stable during the hanging and transportation process.

[0045] When the fixed plate 31 abuts against the top of the connecting seat 51, the solenoid valve 63 switch is triggered, so that the movable block 64 extends from the connecting arm 46. When the quenching basket 3 moves up and down in the quenching medium driven by the driving assembly 4, the movable block 64 on the top of the quenching basket 3 and the guide block 61 on the top of the connecting seat 51 can limit the movable range of the quenching basket 3 itself. Within this range, the movement of the quenching basket 3 itself will not affect the clamping of the telescopic block 53 and the first clamping groove 33. After the metal workpiece is quenched, the winch 43 reels the wire rope 44 and pulls the connecting arm 46 to drive the quenching basket 3 to move up. After the quenching basket 3 is placed at the specified position, the solenoid valve 63 is manually closed through the control center to return the movable block 64 to the connecting arm 46.

[0046] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
