Description

Technical Field

[0001] The utility model belongs to the field of metallurgy, in particular to a crank type flying shear blade replacement structure with a transverse shifting function used on a crank type flying shear for hot rolling of metallurgical machinery. Background Art

[0002] So far, the blade replacement of hot rolling crank flying shears at home and abroad is completed by using a blade replacement device, that is, the blade replacement device acts on the blade to remove the old blade from the flying shear body and install the new blade to the flying shear body, thereby completing the blade replacement. The current blade replacement devices are all offline, that is, the blade replacement device is usually placed in a storage position outside the flying shear body. When the blade needs to be replaced, the blade replacement device is hoisted to the required position for blade replacement by a hoisting machine. After the replacement is completed, the blade replacement device needs to be hoisted back to the storage position. This offline replacement method has the following disadvantages:

[0003] First, the lifting of the shear blade replacement device between the storage position and the position required for replacement requires the investment of lifting machinery, so during lifting, the lifting preparation time is too long and the machinery cost is high;

[0004] Second, the shear blade replacement device is hoisted back and forth between the storage location and the location where the blade needs to be replaced, and various safety hazards along the hoisting path are difficult to eliminate;

[0005] Third, in addition to the cost of machinery, hoisting requires manual operation of the hoisting machinery, manual inspection of the connection between the hoisting machinery and the shear blade replacement device, etc., and the labor input is also large. Utility Model Content

[0006] The utility model aims to provide a crank-type flying shear blade replacement structure with a transverse shift function, thereby reducing replacement time, eliminating potential safety hazards and improving blade replacement efficiency.

[0007] The technical solution adopted by the utility model is: a crank-type flying shear blade replacement structure with a transverse movement function, including a blade replacement device, a flying shear body, an equipment foundation and a foundation pit for waste collection, and also includes a transverse movement platform, a track, a pad and a transverse movement hydraulic cylinder;

[0008] A pad is provided on the operating side of the flying shear body along the longitudinal direction on both sides of the foundation pit, and each pad extends in the transverse direction; and a track extending in the transverse direction is provided on each pad;

[0009] The shear blade replacement device is carried on a transverse moving platform, and the transverse moving platform is arranged on a track and movably connected to the track along the extending direction of the track;

[0011] Furthermore, there are two transverse hydraulic cylinders, which are arranged side by side on the same side of the transverse platform and symmetrically arranged about the transverse center line of the transverse platform.

[0012] Furthermore, the two hydraulic cylinders are longitudinally separated on both sides of the foundation pit and correspond to the rails in the longitudinal direction.

[0013] Furthermore, rollers are installed on the bottom surface of the transverse moving platform, and the transverse moving platform is driven to move on the track by the rollers.

[0014] Furthermore, among the rollers on the bottom surface of the transverse platform, the rollers matched with one of the tracks are flat rollers, and the rollers matched with the other track are stop rollers.

[0015] Furthermore, it also includes a waste collection device, which includes a trolley, a hopper and a hydraulic cylinder located in the foundation pit, the trolley is driven by the hydraulic cylinder to move horizontally in the foundation pit, and the hopper is placed in the trolley;

[0016] In the horizontal direction, the leftmost position of the transverse moving platform on the track is the left limit position, and the rightmost position is the right limit position; when the transverse moving platform is at the right limit position, the left end of the transverse moving platform and the track on the left side of the transverse moving platform surround to form a left hoisting outlet for the hopper to enter and exit;

[0017] When the transverse moving platform is in the left limit position, the right end of the transverse moving platform and the track located on the right side of the transverse moving platform surround to form a right lifting outlet for the hopper to enter and exit.

[0018] The beneficial effects of the utility model are as follows: in the utility model, the shear blade replacement device is carried on a transverse moving platform, and the transverse moving platform is provided on a track and movably connected with the track along the extension direction of the track, so that the shear blade replacement device follows the transverse moving platform to move laterally on the track, thereby realizing the shear blade replacement device to be quickly moved to the position required for shear blade replacement, and there is no need to lift the shear blade replacement device separately, thereby eliminating the safety hazard of lifting, saving lifting costs, saving lifting time, and improving the efficiency of shear blade replacement.

[0019] The shear blade replacement device is carried on the transverse platform and moves horizontally along the track, and cooperates with the trolley of the waste collection device in the bottom foundation pit to carry the bucket. The bucket and the transverse platform move in coordination to expose the hoisting outlet of the bucket, so that the shear blade replacement device does not need to be lifted separately when lifting the bucket, eliminating the safety hazard of lifting, saving lifting costs, saving bucket lifting time, and improving the efficiency of waste bucket replacement.

DETAILED DESCRIPTION

[0026] The present invention is further described below in conjunction with the accompanying drawings and embodiments:

[0027] In the present invention, the terms "vertical", "lateral", "longitudinal", "left", "right", "upper" and "lower" indicate directions or positional relationships based on the attached Figure 1 The orientation or positional relationship shown is only for the convenience of describing the present invention, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0028] The traditional flying shear blade replacement structure includes a blade replacement device 2, a flying shear body 6, an equipment foundation 10 and a foundation pit 11 for waste collection. The blade replacement device 2 acts on the blade to remove the old blade from the flying shear body 6 and install the new blade to the flying shear body 6, thereby completing the replacement of the blade. Normally, the blade replacement device 2 is placed in a storage position outside the flying shear body 6. When the blade needs to be replaced, a hoisting machine is used to hoist the blade replacement device 2 to the required position for blade replacement. After the replacement is completed, the blade replacement device 2 needs to be hoisted back to the storage position. Since the hoisting machine needs to be invested, the hoisting preparation time is too long, the hoisting cost is high, and there are safety hazards in the hoisting path. In order to understand the problems existing in the traditional structure, the utility model has been improved on the basis of the traditional structure to form a crank-type flying shear blade replacement structure with a transverse shift function, such as Figure 1 and Figure 2As shown, it not only includes a shear blade replacement device 2, a flying shear body 6, an equipment foundation 10 and a foundation pit 11 for waste collection, but also includes a transverse platform 1, a track 4, a pad 5 and a transverse hydraulic cylinder 3;

[0029] On the operating side of the flying shear body 6, a pad 5 is provided on both sides of the foundation pit 11 in the longitudinal direction, and each pad 5 extends in the transverse direction; and on each pad 5, a track 4 extending in the transverse direction is provided;

[0030] The shear blade replacement device 2 is carried on the transverse platform 1, and the transverse platform 1 is provided on the track 4 and is movably connected to the track 4 along the extension direction of the track 4, that is, the shear blade replacement device 2 follows the transverse platform 1 to move laterally on the track 4, so that the shear blade replacement device 2 can be moved to a shear blade replacement position where the shear blade can be replaced. After the replacement is completed, the shear blade replacement device 2 can be moved to the side by the transverse platform 1, away from the shear blade replacement position, to avoid affecting subsequent operations. Through the transverse movement of the shear blade replacement device 2, the shear blade replacement device 2 can be quickly moved to the position required for shear blade replacement, without the need for separate lifting, eliminating the safety hazard of lifting, saving lifting costs, and saving lifting time, thereby improving the efficiency of shear blade replacement.

[0031] The lateral moving platform 1 is driven to move by the lateral moving hydraulic cylinder 3 , which is located on one side of the lateral moving platform 1 in the transverse direction. One end of the lateral moving hydraulic cylinder 3 is fixed on the equipment foundation 10 , and the other end is hinged to the end of the lateral moving platform 1 .

[0032] If a transverse shift hydraulic cylinder 3 is installed in the middle of one side of the transverse shift platform 1, the transverse shift platform 1 can also be shifted horizontally, but it is difficult to ensure the stability of the movement. In order to overcome this problem, in this embodiment, there are two transverse shift hydraulic cylinders 3, and the two hydraulic cylinders are arranged side by side on the same side of the transverse shift platform 1 and symmetrically about the transverse center line of the transverse shift platform 1.

[0033] If the two transverse hydraulic cylinders 3 are located above the foundation pit 11 and aligned with the foundation pit 11, it will interfere with the subsequent vertical lifting path of the waste in the foundation pit 11. In order to avoid this problem, preferably, the two transverse hydraulic cylinders 3 are separated on both sides of the foundation pit 11 along the longitudinal direction and correspond to the track 4 along the longitudinal direction, that is, one transverse hydraulic cylinder 3 is arranged above one track 4. In this way, the transverse hydraulic cylinder 3 will neither be at the pit mouth of the foundation pit 11 nor can it more effectively drive the transverse platform 1 to move along the track 4.

[0034] The traverse platform 1 and the track 4 can be moved in a sliding manner by connecting with a slide groove. In this embodiment, rollers are installed on the bottom surface of the traverse platform 1, and the rollers drive the traverse platform 1 to move on the track 4. By moving on the track 4 with rollers, the friction force is smaller, and it is easier to drive the traverse platform 1 to move, thereby reducing the requirements for the traverse hydraulic cylinder 3.

[0035] In order to limit the transverse platform 1 in the longitudinal direction and avoid the derailment of the transverse platform 1 in the longitudinal direction, preferably, among the rollers on the bottom surface of the transverse platform 1, a flat roller 8 cooperates with one of the tracks 4, and a stopper roller 9 cooperates with the other track 4. The stopper roller 9 can limit the transverse platform 1 in the longitudinal direction.

[0036] Preferably, Figure 3 As shown, it also includes a waste collection device 7, which includes a trolley 7A, a hopper 7B and a hydraulic cylinder located in the foundation pit. The trolley 7A is driven by the hydraulic cylinder to move horizontally in the foundation pit, and the hopper 7B is placed in the trolley 7A; the waste collection device 7 is used to collect waste, and the waste is directly collected in the hopper 7B of the waste collection device 7. The setting of the hopper 7B facilitates the overall lifting of the hopper 7B to transport the waste out. The setting of the trolley 7A facilitates the transportation of the hopper 7B to a suitable lifting position in the foundation pit for lifting. The hydraulic cylinder is used to drive the trolley 7A to move.

[0037] In the longitudinal direction, the foundation pit is located between two rows of rails 4, so that when the bucket 7B is hoisted, the rails 4 on both sides will not interfere with the bucket 7B.

[0038] In the horizontal direction, the leftmost position of the traverse platform 1 on the track 4 is the left limit position, and the rightmost position is the right limit position; Figure 4 As shown, when the transverse platform 1 is at the right limit position, the left end of the transverse platform 1 and the track 4 located on the left side of the transverse platform 1 surround the left side of the transverse platform 1 to form a left side lifting outlet 12 for the hopper 7B to enter and exit. When the hopper 7B needs to be lifted from the left side lifting outlet, the transverse platform 1 is first moved to the right limit position. Figure 5 As shown, when the transverse moving platform 1 is in the left limit position, the right end of the transverse moving platform 1 and the track 4 located on the right side of the transverse moving platform 1 surround to form a right lifting outlet 13 for accommodating the hopper 7B to enter and exit. When it is necessary to lift the hopper 7B from the right lifting outlet, first move the transverse moving platform 1 to the left limit position. This structural setting makes it unnecessary to lift the shear blade replacement device 2 when lifting the hopper 7B, making it more convenient to replace and lift the waste hopper 7B, reducing labor intensity, eliminating safety hazards, and improving the efficiency of hopper replacement. The two-way outlet settings of the right lifting outlet and the left lifting outlet can be used in conjunction with each other to better adapt to the lifting environment requirements.
