Description

Technical Field

[0001] The present application relates to the field of overhead cranes, and in particular to an overhead crane for roller transfer. Background Art

[0002] Roller is the main working part and tool on the rolling mill that causes continuous plastic deformation of metal. Roller is mainly composed of three parts: roll body, roll neck and shaft head. Roller body is the middle part of the roll that actually participates in rolling metal. It has a smooth cylindrical or grooved surface. Roller neck is installed in the bearing and transmits the rolling force to the frame through the bearing seat and the press device.

[0003] Since the rollers themselves are heavy, the rollers are usually hoisted and transferred by means of a crane in combination with a crane during the hoisting process. The crane currently used for hoisting rollers generally uses two support plates that are arranged oppositely and connected to each other, and each support plate is provided with a through hole for inserting the roller neck. During the hoisting process, the two roller necks of the roller are inserted into the through holes provided on different support plates, and then the two support plates are hoisted by a crane to realize the hoisting process of the roller.

[0004] During the process of hoisting the rollers in the above manner, since the holes on the support plate have a constant size, the overhead crane can only hoist rollers of a single size, which is inconvenient. Utility Model Content

[0005] In order to realize the hoisting process of rollers of different sizes, the present application provides a roller transfer overhead crane.

[0006] The present application provides a roller transfer overhead crane that adopts the following technical solution:

[0007] A roller transfer overhead crane comprises two support plates arranged opposite to each other, and a plurality of guide rods arranged at intervals are arranged between the two support plates, the end of each guide rod passes through one of the support plates and is slidably connected to the support plate, each support plate is provided with a placement hole passing through the support plate, and the placement holes provided on the two support plates are arranged opposite to each other, a plurality of abutment plates are arranged inside each placement hole, and a pressure spring is fixedly connected between the hole wall of each abutment plate close to the adjacent placement hole and the adjacent hole wall.

[0008] By adopting the above technical solution, in actual use, the roll neck of the rolling mill is inserted into the placement hole of the adjacent support plate, and the roll neck is inserted into the position between multiple abutment plates inside the placement hole. Then, driven by the pressure spring, multiple abutment plates abut against the roll neck to realize the clamping process of the roll neck, thereby reducing the trouble of the placement hole having a constant size and only being able to hoist a roll of a single size.

[0009] Optionally, two opposite side walls of each abutment plate arranged along the length direction of the guide rod are connected to a guide plate, and each guide plate is inclined along a side close to the connected abutment plate and away from the connected abutment plate, and is inclined toward a side away from the center line of the adjacent placement hole.

[0010] By adopting the above technical solution and providing a guide plate, the trouble of difficulty in controlling the position during the process of inserting the roll neck between multiple abutment plates, which causes the roll neck to abut against the side wall of the guide roller, is reduced.

[0011] Optionally, each of the support plates is connected to a clamping assembly, and each clamping assembly can limit the position of multiple abutment plates connected to the same support plate from the center line of the placement hole.

[0012] By adopting the above technical solution and providing the clamping assembly, the phenomenon that the roller neck squeezes the pressure spring under the action of gravity and the abutment plate is unable to fully clamp the roller neck is reduced in the actual practical process.

[0013] Optionally, the clamping assembly includes a clamping rod fixedly connected to a side of each abutment plate close to a pressure spring, and a side of each clamping rod away from the connected abutment plate is slidably inserted into the hole wall of an adjacent placement hole, and a clamping block is provided on a side of the support plate close to each clamping rod, and one side of each clamping block can abut against the clamping rod, and the side of each clamping block that can abut against the clamping rod is set as an inclined surface.

[0014] By adopting the above technical solution, when the roll neck is inserted into a position between multiple abutment plates, the movable clamping block drives the clamping rod to move, so that the clamping rod drives the abutment plate to fully abut against the roll neck, so that the abutment plate can fully clamp the roll neck.

[0015] Optionally, a non-return ratchet is fixedly connected to one side of each of the blocking blocks, and a fixed ratchet that can engage with the non-return ratchet is fixedly connected to the inside of the support block near each of the blocking blocks, and when the non-return ratchet is engaged with the fixed ratchet, the blocking block can limit the tendency of the blocking rod to move toward the inside of the support plate.

[0016] By adopting the above technical solution, by setting a non-return ratchet and a fixed ratchet, when the block abuts the pull rod, the non-return ratchet and the fixed ratchet are engaged with each other, thereby reducing the abutment plate from driving the clamping rod to move toward the side close to the block when being squeezed, making it difficult for the clamping rod to limit the abutment plate.

[0017] Optionally, each of the clamping blocks is connected to a pull rod, and a plurality of pull rods connected to the same support plate are fixedly connected to the same pull ring.

[0018] By adopting the above technical solution and providing a pull ring and a pull rod, it is convenient for the staff to simultaneously drive the movement of multiple blocks connected to the same support plate.

[0019] Optionally, each of the support plates is connected to a limiting assembly, and the limiting assembly is used to limit the relative position of the support plate and the plurality of guide rods connected thereto.

[0020] By adopting the above technical solution and setting the limit assembly, the phenomenon that the position of the support plate moves during the lifting and moving process, resulting in difficulty in fully clamping the roll neck, is reduced.

[0021] Optionally, multiple limit rods are slidably inserted into the support plate, and each of the limit rods is arranged corresponding to one of the adjacent guide rods and the end can abut against the corresponding guide rod side wall, and multiple limit rods connected to the same support plate are abutted against the same stop block at one end away from the corresponding guide rod, and the side walls where the stop block abuts against each limit rod are both inclined surfaces that gradually incline from top to bottom toward the side of the abutting guide rod, and each stop block is slidably inserted into the support plate in a vertical direction and a hanging ring is sleeved on the outside of each stop block.

[0022] By adopting the above technical solution, in the process of moving the roller by pulling the lifting ring through the steel cable, the lifting ring drives the stop block to move, and the stop block drives the connected limit rod to move during the movement, so that the limit rod abuts against the adjacent guide rod, thereby realizing the limitation of the relative position of the support plate and the guide rod.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. By arranging a plurality of abutment plates and pressure springs inside the placement hole, the clamping process of roll necks of different sizes can be realized, thereby realizing the process of hoisting and moving rolls of different sizes;

[0025] 2. By setting up the clamping assembly, the phenomenon that the abutment plate is displaced when squeezed by the roller during the lifting and moving process, which makes it difficult to fully clamp the roller, is reduced;

[0026] 3. By setting the limit assembly, the phenomenon that the support plate moves during the process of lifting the roller, making it difficult to fully clamp the roller, is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1 -Attached Figure 3 This application is described in further detail.

[0032] The present application embodiment discloses a roller transfer crane, referring to Figure 1 and Figure 2 , including two support plates 1, the two support plates 1 are arranged opposite to each other and in parallel, and two horizontally arranged and mutually parallel guide rods 2 are arranged between the two support plates 1. The end of each guide rod 2 passes through the adjacent support plate 1 and is slidably connected to the support plate 1, and each guide rod 2 is vertically arranged to the connected support plate 1.

[0033] Each support plate 1 is provided with a placement hole 11 penetrating through the support plate 1 at a position located below the connected guide rod 2, and a plurality of abutment plates 3 are provided inside each placement hole 11, each abutment plate 3 is arranged in an arc shape and a plurality of abutment plates 3 are distributed in a circular ring shape. A pressure spring 31 is fixedly connected to one side of each abutment plate 3 close to the hole wall of the adjacent placement hole 11, and a side of each pressure spring 31 away from the connected abutment plate 3 is fixedly connected to the hole wall of the adjacent placement hole 11.

[0034] When the roll needs to be hoisted, the roll neck is inserted into the through hole of the adjacent support plate 1, and then the pressure spring 31 drives the connected abutment plate 3 to abut against the adjacent roll neck, thereby realizing the clamping process of the roll neck, and then the two support plates 1 are hoisted at the same time by the sling to realize the hoisting process of the roll.

[0035] The connected abutment plate 3 is driven by the pressure spring 31 to abut against the roll neck to clamp the roll neck, thereby realizing the clamping process of rolls of different sizes, and further enabling the overhead crane to hoist rolls of different sizes.

[0036] Each abutment plate 3 is rotatably connected to two opposite side walls of the guide rod 2 in the length direction, and each guide plate 32 is inclined gradually from a side close to the connected abutment plate 3 to a side away from the connected abutment plate 3 and away from the center line of the adjacent placement hole 11.

[0037] By providing the guide plate 32 and slanting the guide plate 32 , it is more convenient to insert the roll neck into the middle of the plurality of abutment plates 3 under the guidance of the guide plate 32 .

[0038] Each support plate 1 is connected with a clamping assembly 4 , and the clamping assembly 4 is used to limit the position of the abutting plate 3 .

[0039] In actual use, after the roll neck is inserted into the middle of the plurality of abutment plates 3, the position of the abutment plates 3 is restricted by the clamping assembly 4, so that the abutment plates 3 can stably support the roll neck during the lifting process.

[0040] The clamping assembly 4 includes a clamping rod 41 fixedly connected to the side of each abutting plate 3 close to the connected pressure spring 31, and the side of each clamping rod 41 away from the connected abutting plate 3 is inserted into the hole wall of the adjacent placement hole 11 and slides against the hole wall of the placement hole 11. A clamping block 42 is provided on one end of each clamping rod 41 inserted into the inside of the support plate 1 and close to another unconnected support plate 1, and the side of each clamping block 42 close to the adjacent clamping rod 41 is set as an inclined surface, and the inclined surface is gradually inclined from the side away from the adjacent clamping rod 41 to the side close to the adjacent clamping rod 41 to the side away from the center line of the adjacent placement hole 11, and the inclined side wall of each clamping block 42 can abut against one end of the adjacent clamping rod 41 located inside the support plate 1.

[0041] A pull rod 43 is fixedly connected to one side of each block 42 away from another unconnected support plate 1, and one end of each pull rod 43 away from the connected pull block penetrates the support plate 1 and is slidably connected to the support plate 1. Multiple pull rods 43 connected to the same support plate 1 penetrate the ends of the connected support plates 1 and are fixedly connected to the same pull ring 44.

[0042] Each pull block is slidably inserted into the support plate 1 along the length direction of the connected pull rod 43, and each pull block is fixedly connected to a plurality of non-return ratchets 45 on the side away from the adjacent abutment plate 3, and a plurality of fixed ratchets 46 are fixedly connected to the side of the support plate 1 close to each pull block, and the adjacent fixed ratchets 46 and non-return ratchets 45 are engaged with each other during the process of the pull block moving toward the side away from the connected pull ring 44.

[0043] When the multiple abutment plates 3 abut against the roll neck, pull the pull ring 44 so that the pull ring 44 drives the connected multiple clamping blocks 42 to abut against the adjacent clamping rods 41, and through the clamping of the non-return ratchet 45 and the fixed ratchet 46, the clamping blocks 42 can stably abut against the clamping rods 41, and the clamping rods 41 drive the abutment plates 3 to stably abut against the roll neck, thereby realizing the process of fully clamping the roll neck.

[0044] Reference Figure 3Each support plate 1 is connected to a limiting assembly 5 , and the limiting assembly 5 is used to limit the relative position of the connected support plate 1 and the two guide rods 2 .

[0045] By providing the limiting assembly 5, during the process of hoisting the support plates 1, the relative positions of the two support plates 1 can be limited by the limiting assembly 5, thereby making the hoisting and transfer process more stable.

[0046] The limiting assembly 5 includes two limiting rods 51 that are slidably inserted into the support plate 1 in the horizontal direction. The two limiting rods 51 are arranged opposite to each other, and the opposite ends of the two limiting rods point to one of the adjacent guide rods 2 and can abut against the adjacent guide rod 2. The opposite ends of the two limiting rods 51 point to the same stop block, and the side walls of the stop blocks 52 close to each limiting rod 51 are gradually inclined from top to bottom toward the side of the adjacent limiting rod 51. Each stop block 52 is slidably inserted into the support plate 1 in the vertical direction and is provided with a hanging ring 53 on the outside.

[0047] During the hoisting process, the lifting ring 53 is connected by a steel cable and driven to move upward, and the lifting ring 53 drives the stopper 52 to move upward during the upward movement. The stopper 52 drives the two adjacent limit rods 51 to move away from each other during the upward movement, and each limit rod 51 can abut against the adjacent guide rod 2 during the movement, thereby limiting the position of the connected support plate 1 and the adjacent guide rod 2.

[0048] The implementation principle of a roller transfer overhead crane in an embodiment of the present application is as follows: when the roller needs to be lifted and transferred, the roller neck is inserted into a position between multiple abutment plates 3 connected to adjacent support plates 1, and then the pull ring 44 is pulled to further support the abutment plate 3 through the clamping rod 41.

[0049] Then, the steel cable is connected to the lifting ring 53 for lifting. During the lifting process, the lifting ring 53 drives the connected limiting rod 51 to abut against the adjacent guide rod 2 to limit the position of the support plate 1.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
