Description

Technical Field

[0001] The utility model belongs to the technical field of auxiliary equipment for medium and heavy plate production, and particularly relates to a heat preservation cover for slow cooling of steel plate stacking, which covers the whole stack of steel plates with heat preservation cloth to achieve the purpose of slow cooling of the steel plates and improve the internal quality of the steel plates. Background Art

[0002] Stacking and slow cooling of medium and heavy plates after rolling is an important production process. Its purpose is to eliminate white spots in the steel plates and release stress, avoid cracks caused by stress during natural cooling. At the same time, for high-alloy steel plates that need to be cut at high temperature, it can play a role in heat preservation and adjusting the production rhythm of the cutting process. Therefore, the slow cooling process has a great relationship with the quality of the steel plates.

[0003] Traditional heat preservation covers can be divided into steel structure type and heat preservation cloth type. The former is a steel structure type with rock wool installed inside. Due to the high manufacturing cost of the steel structure heat preservation cover, it takes a lot of time and effort to transport it with a traveling crane during the handling process, and it is not easy to repair after deformation caused by baking and collision. For steel plates with large length and width specifications and a large number of stack positions, a large number of them need to be manufactured to meet the production needs, and the heat preservation covers occupy a large amount of ground space. In the existing heat preservation cloth type, manual operation is mainly required, that is, the heat preservation cloth needs to be transported, covered and stored by manual and overhead crane cooperation, and it is easily cut by the corners of the steel plates during the pulling process, with a service life of only two or three months. After being damaged, it also affects the heat preservation effect of the steel plates. At the same time, the asbestos fibers of the heat preservation cloth may also cause physical harm to the staff.

[0004] In order to solve the deficiencies in the current heat preservation measures, it is necessary to design a heat preservation cover with an automatic retracting and releasing form. Content of the Utility Model

[0005] The purpose of the utility model is to provide a heat preservation cover for slow cooling of steel plate stacking to solve the problems of high working intensity and easy damage of the heat preservation cloth in the prior art.

[0006] To achieve the above purpose, the technical solution of the utility model is as follows: A heat preservation cover for slow cooling of steel plate stacking, characterized in that: it includes a pulling unit, a guiding unit and a retracting and releasing unit;

[0007] The pulling unit includes an n-shaped pull rod, the lower end of the pull rod is screwed on the pull rod seat, and further includes a pulling motor for driving the pull rod to rotate;

[0008] The guiding unit includes a guiding rod, and the guiding rod is fixed on the ground through a column;

[0009] The retracting and releasing unit includes a reel, both ends of the reel are screwed on the reel seat, and further includes a retracting and releasing motor for driving the reel to rotate;

[0010] One end of the insulation cloth is fixed on the crossbeam of the pull rod, the insulation cloth is wound around the guide rod and arranged on the reel, and the other end of the insulation cloth is fixed on the reel through a pressure strip.

[0011] Furthermore: a heat-insulating cloth is arranged between the two upright posts.

[0012] Furthermore: a rotating shaft I is provided at the lower end of the pull rod, and the rotating shaft I is rotationally matched with the pull rod seat; the pulling motor is matched with the rotating shaft I through a coupling.

[0013] Furthermore: a rotating shaft II is arranged at both ends of the reel, and the rotating shaft II is rotatably matched with the reel seat; the retractable discharge motor is matched with the rotating shaft II through a coupling.

[0014] Furthermore: limit rods are arranged at both ends of the guide rod.

[0015] The beneficial effects of the structure of the utility model are as follows: the structure of the utility model has the functions of automatically controlling the covering, untying and collecting of the insulation cloth, which greatly reduces manual operation and prolongs the service life of the insulation cloth. The insulation cloth is covered by controlling the motor to rotate forward, and the insulation cloth is untied by controlling the motor to rotate reversely. The over-width part of the insulation cloth is controlled within the working length of the reel by the limit rod, which avoids the problem of being drawn into the motor and scratched by the corner of the steel plate. The problem of the insulation cloth being scratched by direct contact with the corner of the steel plate is avoided by the action of the guide rod. After the insulation cloth is covered, only the edges and corners of the insulation cloth need to be properly regularized manually to achieve a complete covering effect. During the collection process of the insulation cloth, only the over-width part of the insulation cloth on the reel needs to be manually adjusted to achieve a neat collection effect without excessive manual operation. The utility model will not cause dragging and scratching problems during the working process, can effectively protect the insulation cloth, increase its service life, and also reduce the labor intensity, so that the steel plate can be completely sealed inside the insulation cover for insulation and slow cooling, which can meet the process requirements.

[0023] 31 is the reel, 32 is the reel seat, and 33 is the winding and unwinding motor. Specific implementation manner

[0024] As Figures 1-4 shown, the present utility model discloses a heat preservation cover for slow cooling of steel plate stacking, which comprises a pulling unit 1, a guiding unit 2 and a winding and unwinding unit 3;

[0025] The pulling unit 1 comprises an n-shaped pull rod 11, which is composed of an upper cross bar and two vertical bars connected to the cross bar. The lower end of the pull rod is screwed on the pull rod seat 12, and further comprises a pulling motor 13 for driving the rotation of the pull rod;

[0026] The guiding unit 2 comprises a guide rod 21, and the guide rod is fixed on the ground through a column 22;

[0027] The winding and unwinding unit 3 comprises a reel 31, the two ends of the reel are screwed on the reel seat 32, and further comprises a winding and unwinding motor 33 for driving the rotation of the reel;

[0028] One end of the heat preservation cloth 4 is fixed on the cross beam of the pull rod. The heat preservation cloth bypasses the guide rod and is wound on the reel, and the other end of the heat preservation cloth is fixed on the reel through a pressing strip.

[0029] Preferably: A heat preservation cloth is arranged between the two columns to improve the heat preservation effect. The heat preservation cloth is close to the guide rod above and does not affect the guiding function of the guide rod.

[0030] Preferably: A rotating shaft I14 is fixedly arranged at the lower end of the vertical bar of the pull rod 11. The rotating shaft I is rotationally matched with the pull rod seat (equivalent to a bearing seat); The pulling motor is matched with the rotating shaft I through a coupling or a gear set 16 structure. Further, a large gear is fixedly arranged on the rotating shaft I, and a small gear is arranged on the output shaft of the pulling motor (or a speed reducer matched with it), and the two are meshed and matched.

[0031] Preferably: Rotating shafts II34 are arranged at both ends of the reel 31. The rotating shafts II are rotationally matched with the reel seat; The winding and unwinding motor is matched with the rotating shaft II through a coupling 35.

[0032] Preferably, limiting rods 5 are provided at both ends of the guide rod 21 to guide the heat-insulating cloth, facilitating winding by the reel; limiting rods are also provided on the reel and the pull rod. The limiting rod on the reel can be fixedly arranged on the reel seat or the outer wall of the reel and rotate with the reel, but does not interfere with the operation of other parts. The limiting rod can play a role in limiting and gathering the heat-insulating cloth, facilitating the winding and unwinding of the reel, and preventing the edge from exceeding the reel and being unable to be effectively wound. The width of the heat-insulating cloth is greater than the distance between the corresponding two limiting rods. During winding, the limiting rod gathers the heat-insulating cloth slightly like a curtain, making it located within the limiting rod. At the same time, manual monitoring and assistance can be carried out.

[0033] Preferably, the length of the heat-insulating cloth is greater than the sum of the stack length and twice the height, and the width of the heat-insulating cloth is greater than the sum of the stack width and twice the height; thus ensuring the effective coverage of the stack by the heat-insulating cloth. After coverage, both sides and the left side can fall to the ground, and the right side is also basically covered. Moreover, there is auxiliary heat-insulating cloth between the two columns on the right side, thus forming a heat-insulating cloth cover with good sealing performance.

[0034] The working process of the structure of the present utility model is as follows:

[0035] In the initial state, i.e., the non-working state, the pull rod is in the retracted state ( Figure 1 middle position) and leans against the upper end of the column. At the same time, the entire heat-insulating cloth is wound on the reel, and the entire stack area 6 is in a ready state. Before the structure works, the steel plates are stacked in the middle area of the stack, and the stack shape is neat. When the stack is completed and the heat-insulating cover is needed to cover the stack, the driving motors of the reel and the pull rod (i.e., the winding and unwinding motor and the pulling motor) are simultaneously rotated forward. The reel starts to release the heat-insulating cloth. At the same time, the pull rod swings to drive the heat-insulating cloth to turn to the head end of the stack ( Figure 1 left side in the middle), until the pull rod lies flat on the ground. Then, the driving motors of the reel and the pull rod are turned off. The main body of the heat-insulating cloth covers the upper surface of the stack, and at the same time, the edge part falls and covers the periphery of the stack. The staff can check and manually adjust the parts that are not fully covered by the heat-insulating cloth according to the situation. When the steel plates need to be unstacked after the stacking is completed, the staff confirms that there are no obstacles and entanglements around the heat-insulating cloth, and adjusts the heat-insulating cloth within the range of the limiting rod. First, the driving motor of the pull rod is rotated in the reverse direction to make the heat-insulating cloth at the head end leave the corner position of the head end of the steel plate. Then, the driving motor of the reel is rotated in the reverse direction. The staff adjusts the heat-insulating cloth collected on the reel at any time to make it in a neat state until the entire heat-insulating cloth is wound on the reel. At this time, the cross bar of the pull rod resets and leans against the column, and the driving motors of the reel and the pull rod are turned off, returning to the initial state.
