Description

Technical Field

[0001] The utility model relates to the technical field of steel rolling, in particular to a hot saw cooling bed collecting frame. Background Art

[0002] In a steel rolling mill, round steel that has been sent down by a hot saw will roll onto a cooling bed collection rack for cooling. A stopper will be provided at the outer end of the cooling bed collection rack to limit the rolled round steel. The existing stopper is an H-shaped steel that stands directly on the cooling bed collection rack for limiting the position. Due to the heavy weight of the round steel and the inclined cooling bed designed for convenient collection, the round steel will directly collide with the stopper when rolling down. The cooling bed platform or the stopper has no buffering measures. The H-shaped steel of the stopper often breaks due to the hard collision, especially at the welding position between the stopper and the cooling bed. For example, the rolling mill cooling bed disclosed in the application number "CN01237818.6" includes an upper roller, a cooling bed platform and a lower roller. The cooling bed platform is composed of a cooling bed frame and a parallel cooling bed straight plate. It is characterized in that: a toggle rod is provided on the outer side of the upper roller, the upper roller plane is inclined toward the cooling bed platform, the cooling bed platform is inclined toward the lower roller, and a cooling bed baffle is provided on the side of the cooling bed platform connected to the lower roller. The baffle is directly installed on the cooling bed platform. Even with multi-stage buffering, it is still impossible to avoid the baffle being easily broken by impact, especially for heavy round steel. Therefore, it is very necessary to design a cooling bed collection rack that can effectively unload the impact force of the baffle. Utility Model Content

[0021] In order to make the purpose, technical solution and advantages of the present invention clearer, the implementation mode of the present invention will be further described in detail below. The present utility model will be further described below in conjunction with the accompanying drawings.

[0022] Embodiment 1:

[0023] A collection frame for a hot saw cooling bed, comprising a bed frame 1, a stopper 2 and a force unloading stopper 3, wherein a guide rail surface 11 arranged obliquely is arranged on the top of the bed frame, the outer end of the guide rail surface is connected to the stopper 2, the guide rail surface gradually decreases from the end away from the stopper to the end close to the stopper, the force unloading stopper is arranged on the top of the guide rail surface and connected to the stopper, the force unloading stopper comprises an arc-shaped guide surface 31 concave downward and toward one side of the stopper, and the lower end of the arc-shaped guide surface is smoothly extended with the guide rail surface. A support rail 12 is arranged at the symmetric center of the top of the guide rail surface, the length direction of the support rail 12 is arranged along the length extension direction of the guide rail surface, and the outer end of the support rail extends into the force unloading stopper.

[0024] Generally, the cooling bed for collecting round steel is composed of multiple groups of cooling bed collecting frames arranged side by side, so that the round steel can be supported by multiple cooling bed collecting frames. In order to ensure the strength of the collecting frame, its base cannot be made too narrow. If it is too wide, it will cause greater wear on the surface of the round steel. Therefore, a supporting rail is set on the top of the guide surface to contact the round steel, thereby ensuring the overall strength of the bed frame and ensuring that the round steel is not easy to wear and has better integrity.

[0025] The lower edge of the arc guide surface is smoothly extended with the upper surface of the support rail 12, and an introduction hole is opened at the lower edge of the arc guide surface, and the support rail is inserted into the introduction hole. The above structure is set to ensure that the round steel has no too small angle at the joint point between the arc guide surface and the support rail, and the round steel can roll smoothly along the arc guide surface, ensuring that the impact force is reduced as much as possible and the efficiency of unloading is improved.

[0026] Since the force unloading stopper arranged on the inner side of the stopper contacts the falling round steel for the first time, the round steel is rolled upward along the arc guide surface, thereby removing the impact force of the round steel and playing a good buffering role, which greatly reduces the impact force received by the stopper, making the stopper not easy to be damaged, having a long service life, and the service life of the entire cooling bed collection rack is also longer.

[0027] Embodiment 2:

[0028] The difference from the above embodiments is that the force-releasing stopper further includes a support plate 32 connected between the arc-shaped guide surface 31, the stopper 2, and the guide rail surface 11. The support plate is directly or indirectly connected to the stopper and the guide rail surface. The periphery of the support plate can be welded to the guide rail surface, the stopper, and the arc-shaped guide surface respectively, so as to ensure the support strength and improve the connection strength between the stopper and the bed frame from multiple positions. Of course, connecting plates 33 can be provided between the support plates and behind the arc-shaped guide surface to connect the connecting plates with the stopper.

[0029] Embodiment Three:

[0030] The difference from the above embodiments is that the included angle between the stopper and the guide rail surface is greater than or equal to 90 degrees. The stopper includes a front bearing plate 21 on the side close to the force-releasing stopper, a rear bearing plate 22 on the side far from the force-releasing stopper, and a connecting plate 23 connecting the front and rear bearing plates. The width of the front bearing plate is greater than that of the rear bearing plate. The force-releasing stopper is directly welded to the front bearing plate or the force-releasing stopper is connected to the stopper through a spring 4. Preferably, the stopper is an upright I-beam, and the front side of the stopper is provided with a widened front bearing plate 21. The bed frame further includes a horizontal I-beam and a concrete base 24 covering the I-beam.

[0031] When the force-releasing stopper is connected to the stopper through the spring 4, through holes are opened on the front bearing plate, the spring passes through the through holes, and both ends of the spring are fixedly connected to the rear bearing plate and the rear surface of the force-releasing stopper respectively. A track groove is provided on the guide rail surface, and the bottom of the force-releasing stopper can reciprocate along the track groove. Through the above structure, when the force-releasing stopper is impacted by the round steel, not only can a part of the impact force be removed by the arc-shaped guide surface, but also a part of the impact force can be removed by the buffering of the spring, so as to better release the impact force of the round steel and ensure that the baffle and the connected components are not easily damaged.

[0032] Embodiment Four:

[0033] The difference from the above embodiments is that a guide cylinder 5 passing through the through hole on the front bearing plate is provided at the rear side of the force-releasing stopper, the spring is arranged inside the guide cylinder, and the length of the guide cylinder is less than the distance between the front bearing plate and the rear bearing plate. The setting of the above structure makes the buffering of the spring more stable and effective. And through the setting of the above distance, it is ensured that when the spring reaches the compression limit in this design, the connecting plate 33 of the force-releasing stopper can lean against the front bearing plate, and the large-area contact can also reduce the pressure, ensuring that the equipment is not easily damaged. The spring can be two symmetrically arranged or multiple.

[0034] Embodiment Five:

[0035] The difference from the above embodiment is that the upper end of the guide surface extends from the upward arc surface and bends back toward the inner end of the guide surface or extends to the upward plane or first extends to the upward plane and then bends back toward the inner end of the guide surface to form an anti-escape head 13. During the collection process of round steel, some round steels may roll too high along the arc guide surface and escape from the arc guide surface and the cooling bed. The anti-escape head that bends back can effectively prevent the round steel from escaping.

[0036] During use of the present application, the force unloading stopper arranged on the inner side of the stopper head contacts the falling round steel for the first time, and the round steel is rolled upward along the arc-shaped guide surface, thereby unloading the impact force of the round steel and playing a good buffering role, greatly reducing the impact force received by the stopper head, thereby making the stopper head not easy to be damaged, having a long service life, and the service life of the entire cooling bed collection rack is also longer.

[0037] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced by equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
