Description

Technical Field

[0001] The utility model belongs to the field of steel plant production, and specifically relates to a large-scale draw-arm box. Background Art

[0002] The cold rolling process is to further thin the raw steel plate to the target thickness. However, after rolling, the head and tail of the steel plate usually have uneven deformation and / or surface quality defects, which require cutting, thereby generating shear scrap. In order to recycle these shear scrap, the bucket of a bucket transporter is usually placed at the cutting station to collect the shear scrap, and then the bucket transporter transports the bucket containing the shear scrap to the yard for dumping the shear scrap, and then transports the dumped bucket back to the cutting station. However, in actual work, in order to facilitate the statistics of scrap rate, weighing sensors are usually installed on the bucket transporter, and the bucket transporter is dispatched to transport the bucket according to the preset interval time combined with the material batch. That is, the bucket transporter is dispatched according to the preset interval time under the same material batch. When the remaining time of the material batch is less than the preset interval time, the bucket transporter is directly dispatched to transfer the bucket with scrap plates after the end of the material batch, so as to avoid the mixed loading of sheared scrap steel generated by two adjacent material batches affecting the statistics of scrap rate; in this way, some buckets will inevitably be transported to the yard for dumping by the bucket transporter before they are fully loaded, resulting in waste of the bucket transporter's transportation capacity. In order to reduce the waste of the bucket transporter's transportation capacity, a large arm box is generally set up in the vacant area between the cutting station and the stockpile yard to collect the sheared scrap steel in multiple buckets that are not fully loaded, thereby reducing the number of times the bucket transporter goes to the stockpile yard and improving the transportation efficiency of the bucket transporter.

[0003] However, the existing arm boxes all feed materials from the top. When the arm box has a large volume and a high height, it cannot be directly connected to the bucket on the bucket transport vehicle. Other auxiliary equipment is required to transfer the sheared scrap steel in the bucket to the arm box, which greatly increases the difficulty of transferring the sheared scrap steel in the bucket and is not conducive to achieving rapid transfer of the scrap steel in the bucket on the bucket transport vehicle. Utility Model Content

[0004] In view of the above shortcomings of the prior art, the purpose of the utility model is to provide a large-scale arm box that can be directly connected to the bucket on the bucket transport vehicle to achieve rapid transfer of sheared scrap steel in the bucket.

[0005] To achieve the above-mentioned purpose and other related purposes, the utility model provides a large-scale arm-drawn box, comprising a box body with an open top, a hook arm being provided at the front of the box body; a feed door being provided on the left or right side of the box body, and a discharge door being provided on the rear side of the box body; the lower end of the feed door is hinged to the box body, and an automatic telescopic mechanism for driving the feed door to flip up and down is hinged on the box body; the upper end of the discharge door is hinged to the box body, and the lower part of the discharge door is connected to the box body by a locking mechanism; a mounting cavity is formed at the front of the box body, and a control device and a power supply device are provided in the mounting cavity; the power supply device includes a battery; the utility model reduces the height of the feed port of the box body by means of an additional feed door, so as to facilitate smooth docking with the bucket on the bucket transport vehicle, thereby realizing the rapid transfer of scrap steel in the bucket.

[0006] Preferably, the locking mechanism includes a limiting column fixedly mounted on the discharge door and a locking hook rotatably mounted on the box body and cooperating with the limiting column. The locking hook and the limiting column can be locked or separated by simply rotating the locking hook, thereby effectively reducing the difficulty of locking the discharge door.

[0007] Preferably, a plurality of rollers spaced apart in the left-right direction of the box body are provided at the bottom rear end of the box body to prevent the bottom end of the drawbar box from being damaged by friction with the ground when the drawbar truck is loading and unloading a large drawbar box.

[0008] Preferably, an inclined baffle extending upward from back to front is provided at the top front end of the box body, and the inclined baffle shields the hook arm to prevent the material from falling and damaging the hook arm when the suction cup is used to transfer the material.

[0009] Preferably, the automatic telescopic mechanism is a hydraulic cylinder, and the control device is a hydraulic pump station, so as to provide sufficient supporting force for the feed door.

[0010] Preferably, the power supply device comprises a charging cable for charging the battery.

[0011] As described above, the large-scale arm-lift box of the utility model has the following beneficial effects:

[0012] By adding a feed door to the side wall of the box, the height of the feed port of the box is lowered to facilitate direct docking with the bucket on the bucket transport vehicle, so that the scrap steel in the bucket can be quickly dumped and transferred to the large wall-pulling box, reducing the difficulty of transferring the scrap steel; and the rollers at the bottom of the box can prevent the arm-pulling box from direct friction with the ground when loading or unloading, thereby increasing the service life of the box; in addition, when the arm-pulling box is dumping scrap steel, there is no need to set up an additional pushing mechanism. You only need to use the arm of the arm truck to lift the front end of the box and release the locking mechanism. The scrap steel in the arm-pulling box can be automatically discharged under the action of its own weight. BRIEF DESCRIPTION OF THE DRAWINGS

The change or adjustment of their relative relationship should also be regarded as the scope of the implementation of the utility model without substantial changes in the technical content. The content can easily understand other advantages and effects of the utility model.

[0022] The large-scale hook-arm box involved in the utility model is used for the reverse transportation of cut and tail scrap steel in a cold rolling mill. It is placed in an idle area between the cutting station and the stockpile to centrally collect the scrap steel in the partially loaded buckets on multiple bucket transport vehicles 01, thereby reducing the number of times the partially loaded buckets go to the stockpile and reducing the waste of the transport capacity of the bucket transport vehicles 01.

[0023] like Figures 1 to 4As shown, the large-scale arm-lifting box provided by the utility model comprises a box body 1 with an open top, a feed door 3 and a discharge door 4 arranged on the box body 1. Among them, a feed port is arranged on the left or right side of the box body 1, and the feed port passes through the top opening upward, and the bottom end of the feed port needs to be no higher than the bucket 02 in the unloading state on the bucket transport vehicle 01, so that the bucket 02 on the bucket transport vehicle 01 can directly dock with the feed port to complete the unloading action; the lower end of the feed door 3 is hinged to the box body 1, and an automatic telescopic mechanism 5 is hinged on the box body 1, and the automatic telescopic mechanism 5 is used to drive the feed door 3 to flip up and down to open or close the feed port of the large arm-lifting box; the upper end of the discharge door 4 is hinged to the box body 1, and the lower part of the discharge door 4 is connected to the box body 1 through a locking mechanism, so that when the locking mechanism When the structure is released and the front end of the large arm box is lifted, the unloading door 4 will open under the gravity of the scrap steel in the large arm box to complete the dumping action; the front part of the box body 1 is provided with a hook arm 2, which can be connected with the arm of the arm truck to automatically complete the loading, unloading and front end lifting of the large arm box under the action of the arm, so as to facilitate the transportation and dumping of the large arm box; the front part of the box body 1 is formed with an installation cavity, and a control device and a power supply device are arranged in the installation cavity, the control device is connected to the automatic telescopic mechanism 5, and the power supply device includes a battery 7, the battery 7 can be disassembled and charged, and can also be directly charged with a charging line.

[0024] It is understandable that the structure of the locking mechanism has various forms, such as the common fixed sleeve and sliding latch lock or the fence door lock disclosed in patents such as 202311695911.6, etc., which is not limited to this. Based on the convenience of operation and cost considerations, the locking mechanism of this embodiment is as follows: Figure 3 As shown, it includes a limiting column 61 fixedly mounted on the discharge door 4 and a locking hook 62 rotatably mounted on the box body 1 and matched with the limiting column 61, so that the locking hook 62 and the limiting column 61 can be locked or unlocked by simply rotating the locking hook 62.

[0025] It is understandable that the automatic telescopic mechanism 5 can be any existing driving mechanism that can realize the automatic telescopic function, such as an electric push rod, a cylinder, or a hydraulic cylinder, without limitation; when the automatic telescopic mechanism 5 is a hydraulic cylinder, the control device needs to be a hydraulic pump station.

[0026] When the arm truck is loading and unloading a large arm box, the box body 1 of the large arm box will rub against the ground, causing damage to the box body 1. In order to solve the problem of friction damage to the box body 1, a plurality of rollers 9 are arranged at intervals in the left and right directions of the box body 1 at the bottom rear end of the box body 1.

[0027] Furthermore, an inclined baffle 11 extending upward from back to front is provided at the top front of the box body 1, and the inclined baffle 11 shields the hook arm 2; thus, when the top opening of a large arm box is used as a feed port, the inclined baffle 11 will protect the hook arm 2 to prevent the hook arm 2 from being damaged by falling materials.

[0028] like Figure 5 As shown, when it is necessary to transfer the scrap steel in the bucket 02 on the bucket transport vehicle 01 to the large-scale arm box, it is only necessary to contract the automatic telescopic mechanism 5 to drive the feed door 3 to flip downward to open the side feed port; then, the position of the bucket transport vehicle 01 is adjusted to move the bucket transport vehicle 01 to a position where it is docked with the side feed port; then, the bucket transport vehicle 01 performs a bucket dumping action to pour the scrap steel in the bucket 02 into the large-scale arm box to complete the transfer of the scrap steel; then, the bucket transport vehicle 01 sends the bucket 02 with the scrap steel dumped back to the shearing station, and When the scrap steel is dumped, the automatic telescopic mechanism 5 is extended to drive the feed door 3 to flip upward to close the side feed port; this cycle continues until the scrap steel in the large arm box reaches a preset height, and the arm truck can be dispatched to the position of the large arm box, and the large arm box can be loaded onto the arm truck by using the arm truck and then moved to the yard for dumping the scrap steel; when dumping the scrap steel, it is only necessary to unlock the locking mechanism and use the arm truck to lift the front end of the large arm box. In this way, under the action of gravity, the lower end of the unloading door 4 will naturally open an angle, and the scrap steel will slide out under the action of gravity.

[0029] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention.
