Description

Technical Field

[0001] The utility model belongs to the technical field of a hot rolling temper mill line, and particularly relates to a coil saddle arranged on an entry walking beam of the hot rolling temper mill line for removing a hose clamp. Background Art

[0002] The walking beam of the hot rolling temper mill production line is located in the entry area of the unit, used to receive the coils lifted by the overhead crane and transport the coils for subsequent processing. It is an important component of the temper mill production line. The coils need to complete operations such as receiving, removing the bundling tape, and axial alignment on the entry walking beam (some entry walking beams of the temper mill line are equipped with rotating saddles, which can rotate the leading end direction by 90 degrees or 180 degrees). After that, the coils are received by the coil loading trolley and sent to the coil preparation station for operations such as cutting the head.

[0003] The walking beam is divided into a moving beam and a saddle. After the coil is lifted onto the saddle, the moving beam rises to the high position to lift the coil, walks forward by one saddle position at the high position, then descends to the low position, places the coil on the next saddle, walks backward by one saddle position at the low position, and returns to the original position to complete a walking cycle and wait for the next coil to be lifted onto the line.

[0004] Generally, the saddle is designed with 6 - 7 saddle positions. Among them, the 1st - 3rd saddle positions are used to receive the coils lifted by the overhead crane, so they are installed separately and equipped with buffer devices. The 4th - 6th (or 7th) saddle positions are divided into left and right sides, with three saddles on each side as a whole. Grooves with a bundling tape removal station are installed on them for removing ordinary bundling tapes (width 30mm, thickness 1mm). The bundling tape is cut by the operator using a manual bundling tape shear and pulled out from the groove to be separated from the coil.

[0005] High - strength coils are bundled with a hose clamp at the middle position of the coil width. The hose clamp has a thickness of 5mm and a width of 70mm, and the joint part is fastened with an M24 bolt to increase the bundling force and ensure no problems such as bundling tape breakage and coil uncoiling.

[0006] When the coil is being produced in the temper mill unit, the bundling tape or hose clamp needs to be removed. The bundling tape can be removed on the entry walking beam, but due to the large width, thickness, and joint part size of the hose clamp, it cannot be removed on the entry walking beam. If the hose clamp is removed at the off - line ground roll station first, the coil will uncoil and cannot be lifted to the temper mill unit.

[0007] The existing temper mill units do not have the function of removing the hose clamp online. Therefore, high - strength coils bundled with hose clamps cannot be directly produced on the temper mill unit online. It is necessary to re - bundle them before being lifted onto the line, replace the hose clamp with multiple ordinary bundling tapes, and then lift them to the temper mill unit. After removing the bundling tape according to the ordinary bundling tape removal method on the entry walking beam, production can be carried out. This process is extremely inconvenient, resulting in an increase in the process, low efficiency, and potential safety hazards.

[0008] Therefore, it is necessary to design a new coil saddle on the walking beam at the entrance of the hot rolling temper mill line, so that the production line has the function of online removing the hose clamps. High-strength steel coils bundled with hose clamps can be directly unbundled on the temper mill line, and the fixed saddle structure of the walking beam is simple, with low cost and convenient carrying.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0028] like Figures 1-4 This is a structural schematic diagram of a walking beam coil feeding saddle provided at the entrance of a hot rolling flattening line proposed by the utility model. The utility model provides a walking beam coil feeding saddle provided at the entrance of a hot rolling flattening line, comprising a base 6 and a pair of saddles 3 provided on the base 6 for placing steel coils, a pair of hinged seats 8 are provided on the base 6 at one side of the saddle 3, a hinged plate 7 hinged to the hinged seat 8 is provided on the saddle 3, a shock absorbing mechanism 4 is provided between the saddle 3 and the base 6, a throat hoop portion corresponding to the throat hoop 2 on the steel coil 1 is provided on the middle part of the saddle 3, and the throat hoop portion is provided as a square groove 5.

[0029] This embodiment is provided with a saddle 3, a shock absorbing mechanism 4 and an articulated seat 8, and a square groove 5 is provided in the middle of the saddle corresponding to the throat hoop. The shock absorbing mechanism and the articulated seat are used to absorb the impact vibration generated by the placement of the steel coil, and the square groove is used to conveniently pull out the throat hoop. The embodiment has the function of online removal of the throat hoop. The high-strength steel coils bundled with the throat hoop can be directly unbundled on the leveling unit, which reduces the lifting process and improves the production efficiency.

[0030] In this embodiment, the front end of the saddle receives the steel coil, and a shock-absorbing mechanism 4 is arranged underneath to play a buffering role; the rear end of the saddle is a hinged structure, and when the front end receives the steel coil and impacts and compresses the shock-absorbing mechanism 4 downward, the saddle swings around the rear end hinge shaft, thereby reducing the damage of the steel coil to the compressed shock-absorbing mechanism 4 and extending the service life of the shock-absorbing mechanism 4. When the steel coil is hoisted by a crane and placed on the saddle, the steel coil causes an upright downward impact on the saddle under the action of gravity. At this time, the saddle can swing up and down around the rear end hinge shaft and reset under the action of the shock-absorbing mechanism 4 to absorb the impact vibration caused by the placement of the steel coil.

[0031] In this embodiment, the steel coil and the saddle are in a non-contact state at the square groove 5, which avoids the situation that the hose clamp is squeezed between the steel coil and the saddle and cannot be taken out. The square groove 5 can accommodate the width and thickness of the hose clamp. When removing the hose clamp 2, first remove the locking nut 10 and the double-headed screw 9, then one person fixes the upper end 11 of the hose clamp, and the other person passes the lower end 12 of the hose clamp downward along the outer circle of the steel coil in the clockwise direction through the square groove 5, and then takes out the hose clamp 2 from the side of the steel coil to complete the removal function.

[0032] In a preferred embodiment, the saddle 3 includes a bottom plate, side steel plates 27 welded to the left and right of the bottom plate, and a top steel plate 18 welded to the top of the side steel plates 27. A bending part for supporting the steel coil is provided at the inner side of the top steel plate 18 extending out of the side steel plate. The square groove 5 is arranged at the middle position of the bending part. In this embodiment, the saddle 3 uses a box structure. By setting the square groove 5 on the box body, while ensuring the strength of the box body, the space gap for removing the hose clamp is increased, unnecessary bundling removal procedures are reduced, production efficiency is improved, and at the same time, the safety hazard problem caused by removing the hose clamp is solved.

[0033] In a preferred embodiment, the square groove 5 includes angle steels 20 welded to the side wall of the side steel plate and the bottom of the top steel plate, and a pair of side steel plates I. The four sides of the side steel plates I are welded to the side steel plate 27, the top steel plate 18, and the angle steel 20. In this embodiment, the square groove 5 at the middle position of the saddle is set as a semi-enclosed square hole with a width of 250 mm, a horizontal depth of 300 mm, and a vertical depth of 200 mm. The inner wall of the hole is a steel plate welded to the box body to form an integral beam structure, which improves the strength of the saddle while increasing the space, has a stable structure, and effectively realizes the function of removing the hose clamp online.

[0034] In a preferred embodiment, a support angle steel 19 is provided at the bottom of the bending part. One right-angle side of the support angle steel 19 is welded to the side steel plate 27, and the other right-angle side is welded to the bottom of the bending part. In this embodiment, this structure is beneficial to improving the strength of the saddle 3, has a stable structure, and effectively realizes the function of removing the hose clamp online.

A through hole for the shock-absorbing main shaft 22 to pass through is provided on the base. In this embodiment, the shock-absorbing main shaft 22 passes through the set of disc springs 23 and the base 6; when the steel coil 1 is placed on the saddle 3, under the action of the gravity of the steel coil, the saddle 3 swings downward, the shock-absorbing support plate 21 and the shock-absorbing main shaft 22 are squeezed by the downward swinging action of the saddle 3, and the set of disc springs 23 is compressed downward. The set of disc springs 23 plays a role in buffering the impact force of the steel coil.

[0036] In a preferred embodiment, a backing plate supported on the base is provided near the end of the shock-absorbing main shaft 22. An external thread is provided at the end of the shock-absorbing main shaft 22 extending into the through hole. A nut 25 and a locking nut 26 for limiting the backing plate are connected to the external thread. In this embodiment, the disc spring group 23 and the backing plate are fastened by the washer 24, the nut 25 and the locking nut 26.

[0037] In a preferred embodiment, the hinge seat 8 includes an ear seat 14 fixed to the base 6 by anchor bolts 13 and a hinge shaft 17 sleeved on the ear seat 14. A central hole through which the hinge shaft 17 passes is provided on the hinge plate 7. A clamping plate 16 is provided on the side wall of the hinge plate 7 through a connecting bolt 15.
