Description

Technical Field

[0001] The utility model relates to the technical field of billet conveying equipment, in particular to a roller table billet receiving device. Background Art

[0002] During the production process of the bar and wire rod production line in the hot rolling mill of iron and steel, the billets are directly transported from below the production platform to the furnace inlet roller table on the platform through the billet conveyor belt by continuous casting. Due to the height difference between the upper and lower parts of the platform, the billets need to be transported to the furnace inlet roller table through the climbing conveyor belt. Therefore, there is a height difference between the roller table and the climbing conveyor belt. When the billets slide from the climbing conveyor belt to the roller table, due to the heavy weight and large kinetic energy of the billets, it causes serious impact on the roller table, resulting in frequent damage to the roller table and the motor.

[0003] Chinese Patent CN 212551037 U proposes a billet loading device, which includes a plurality of upright V-shaped receiving plates. The plurality of V-shaped receiving plates are arranged in a row at equal intervals between the upper loading table frame body and the roller table. The top of each V-shaped receiving plate is a buffer surface, and both ends of the buffer surface are respectively connected to the billet outlet of the upper loading table frame body and the billet inlet of the roller table. A driving component is arranged within the interval between every two V-shaped receiving plates, and the driving component is used to push the billets onto the roller table. The driving component includes a hydraulic cylinder base fixed on the ground, a hydraulic cylinder is connected to the hydraulic cylinder base, the telescopic end of the hydraulic cylinder is connected to a fork, one end of the fork is rotationally connected to the fork base through a transmission shaft, and the other end of the fork is used to push the billets. This patent avoids the billets directly impacting the roller table and reduces the damage to the roller table.

[0004] However, the above patent has the following defects: (1) It is necessary to set V-shaped receiving plates between the upper loading table and the roller table. And in order to ensure the buffering effect of the V-shaped receiving plates on the billets, the size of the V-shaped receiving plates is generally large, so there is a defect of large floor area. (2) The V-shaped receiving plates need to cooperate with the driving component to transfer the billets onto the roller table. Since a plurality of driving components are set, and during the billet transfer process, it needs to pass through an arc-shaped slope, so a large amount of energy is consumed, and there is a defect of high energy consumption. (3) It is necessary to set a plurality of driving components, and the driving components have many components, so the cost is relatively high. Therefore, it is necessary to propose a new billet receiving solution. Summary of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0027] Embodiment 1

[0028] As Figure 1 shown, a roller table billet receiving device includes a roller table and a billet receiving mechanism provided on one side of the roller table. The roller table includes a plurality of rollers 1 arranged at intervals and a first driving device for driving the plurality of rollers 1 to rotate. In this embodiment, the first driving device includes a plurality of roller table motors 2, and the plurality of roller table motors 2 are respectively connected to the plurality of rollers 1. An interval area is formed between two adjacent rollers 1.

[0029] The billet receiving mechanism includes a receiving shaft 4, a plurality of receiving arms 3, and a second driving device. The receiving shaft 4 is provided on one side of the roller table, and its axis direction is parallel to the conveying direction of the roller table. The receiving shaft 4 is connected to the ground through at least two support frames 5. In this embodiment, the receiving shaft 4 is located on one side of the plurality of roller table motors 2 and is connected to the ground through three support frames 5.

[0030] The plurality of receiving arms 3 are symmetrically arranged on the receiving shaft 4 along the axis direction of the receiving shaft 4, and the end of the receiving arm 3 far from the receiving shaft 4 is the receiving end, and the receiving end extends into the interval area of the roller table and partially overlaps with the roller table in space, improving the space utilization rate. The horizontal projection of the roller 1 is parallel to the horizontal projection of the receiving end of the receiving arm. The end of the receiving arm 3 connected to the receiving shaft 4 is the connecting end, and the connecting end is sleeved outside the receiving shaft 4 and is locked and fixed by bolts, which is convenient for disassembly and assembly. In this embodiment, the number of receiving arms 3 is four, and there is an interval of one roller 1 between two adjacent receiving arms 3 to avoid too large an interval between two adjacent receiving arms 3.

[0031] The second driving device is connected to the receiving shaft 4 and switches the state of the receiving arm 3 by driving the receiving shaft 4 to rotate. The state of the receiving arm 3 includes a billet receiving state and a billet discharging state. In the billet receiving state, the receiving end of the receiving arm 3 is horizontally arranged and is 5 - 10 cm higher than the top of the roller 1, preferably 8 cm. In the billet discharging state, the receiving end of the receiving arm 3 is inclined downward and is lower than the top of the roller 1. In this embodiment, the second driving device is a reduction motor with a self-locking function, and only one motor is required to realize the switching between the billet receiving state and the billet discharging state, without the need to set multiple driving devices. Compared with the existing billet receiving devices, the present utility model has the advantages of simple structure and low cost.

[0032] As Figure 2 、 3As shown in the figure, the roller path is located between the billet receiving mechanism and the unloading rack 7. When the roller path receives the billet, the conveyor belt 8 transports the billet 6 to the unloading rack 7. The billet 6 slides down along the slope of the unloading rack 7. Multiple receiving arms 3 are lifted above the rollers 1 of the roller path, so that the billet 6 first falls onto the receiving arms 3 and then is lowered onto the rollers 1 through the receiving arms 3, reducing the impact of the kinetic energy of the billet 6 on the rollers 1 and avoiding the problem of frequent damage to the rollers 1 and the roller path motor 2.

[0033] Most of the area where the billet receiving mechanism of the present utility model and the roller path overlap in space, effectively reducing the occupied area. In addition, since the distance between the billet receiving end of the receiving arm and the roller 1 of the roller path is very small, the transfer distance of the billet 6 between the unloading rack 7 and the roller path is effectively shortened. The receiving arm 3 can quickly transfer the billet 6 onto the roller path, which is beneficial to improving the billet receiving efficiency. Compared with the existing billet receiving devices, the present utility model has the advantages of a smaller floor area and a higher billet receiving efficiency.

[0034] When the billet receiving mechanism of the present utility model is working, multiple receiving arms 3 move downward after receiving the billet 6, without the need to apply an upward thrust. And multiple receiving arms 3 are driven by a shared receiving shaft 4 and a second driving device, without the need to separately set up a driving device, which can reduce power consumption. Compared with the existing billet receiving devices, the present utility model has the advantage of low energy consumption.

[0036] Based on Embodiment 1, in this embodiment, the roller path billet receiving device further includes a sensor for sensing whether a billet 6 has fallen onto multiple receiving arms 3. The sensor and the second driving device are both electrically connected to the controller. The sensor is a pressure sensor, which is arranged on the top surface of the billet receiving end of the receiving arm 3. The controller is a PLC.

[0037] When the sensor senses that a billet 6 has fallen onto the receiving arm 3, the controller controls the second driving device to work. The second driving device drives the receiving shaft 4 to rotate, and the receiving shaft 4 drives multiple receiving arms 3 to switch from the billet receiving state to the billet releasing state, lowering the billet 6 onto multiple rollers 1. The rollers 1, under the drive of the first driving device, convey the billet 6 to the next working station. After the billet releasing operation is completed, the controller controls the second driving device to work, driving multiple receiving arms 3 to reset and restore the billet receiving state, completing an operation process. The settings of the sensor and the controller realize automatic operation.
