For those of ordinary skill in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0042] The present application is further described in detail below with reference to the accompanying drawings of a flat hollow steel production stable feeding device.

[0043] A flat hollow steel production stable feeding device, comprising an intermediate base 1, the bottom of the intermediate base 1 is provided with a plurality of first sliding channels, and a plurality of placing devices are slidably arranged in the first sliding channels. Steel bars 6 are vertically inserted into the placing devices, and a plurality of steel bars 6 are inserted into each placing device at intervals, so that the steel bars 6 on all placing devices are vertically distributed in a rectangular array. Compared with horizontal stacking, the vertically arranged steel bars 6 have a smaller overall space, and will not slide like stacking, so the safety factor is high.

[0044] The intermediate base 1 is provided with a driving device 10, and the driving device 10 controls the placing devices to enter and exit the first sliding channels. After the placing devices are moved out, the steel bars 6 can be taken out.

[0045] The placing device comprises a U-shaped inner frame 3, a plurality of sleeves 4 are fixed in the middle of the inner frame 3, and a steel bar 6 is vertically inserted into the inside of the sleeve 4.

[0046] In the embodiment, in order to make the steel bar 6 more firm, a circular positioning groove is concavely arranged on the top surface of the bottom beam of the inner frame 3, the bottom of the steel bar 6 is inserted into the circular positioning groove, at least two sleeves 4 are sleeved on each steel bar 6 and are arranged at intervals, the sleeves 4 are fixedly connected through connecting plates, and then the inner frame 3 is connected on the side wall.

[0047] If the sleeve 4 is fixed, the distance between the top surface of the uppermost sleeve 4 and the bottom surface of the inner frame 3 is long, and the stroke of the steel bar 6 during taking and placing must be increased, and the difficulty of taking and placing the steel bar 6 is increased.

[0048] In order to solve the above technical problems, in the embodiment, two layers of sleeves 4 are arranged, the lower sleeves 4 are fixedly connected with the inner frame 3, mounting holes are arranged on the two vertical surfaces of the inner frame 3, a first telescopic device 302 is mounted in the mounting hole, the fixed part of the first telescopic device 302 is fixedly connected with the inner frame 3, and all the upper sleeves 4 are fixedly connected with the telescopic part of the first telescopic device 302.

[0049] In this way, when the steel bar 6 is taken and placed, the placing device is moved out of the middle base 1, then the first telescopic device 302 is actuated to drive the upper sleeves 4 to move downward until the upper sleeves 4 abut against the lower sleeves 4, the stroke of the steel bar 6 during taking and placing is shortened, and the taking and placing are facilitated.

[0050] However, if the steel bar 6 is taken and placed vertically, a large amount of physical strength of the operator is consumed, the labor intensity is increased, and the work efficiency is reduced.

[0051] Therefore, in the embodiment, the outer part of the inner frame 3 is provided with a U-shaped outer frame 2, the inner frame 3 is hingedly connected with the outer frame 2, so that the inner frame 3 can rotate. In order to avoid that the rotating angle is too large and an accident occurs, a limiting rotation groove 201 is arranged on the top of the vertical edge of the outer frame 2, the limiting rotation groove 201 comprises a circular hole in the middle and an arc-shaped hole connected through the outside of the circular hole, a rotating shaft is arranged on the top of the vertical edge of the inner frame 3, a limiting rotation block 301 is protrusively arranged on the circumferential surface of the rotating shaft, and the rotating shaft and the limiting rotation block 301 are rotationally arranged in the limiting rotation groove 201. The limiting rotation block 301 rotates in the arc-shaped hole of the limiting rotation groove 201, therefore, the arc of the arc-shaped hole limits the rotating angle of the limiting rotation block 301, so that the rotating angle of the limiting rotation block 301 is 30° to 60°.

[0052] In this way, when the steel bar 6 is taken and placed, the placing device is moved out of the middle base 1, then the inner frame 3 drives the steel bar 6 to rotate, the steel bar 6 is taken and placed in the horizontal direction, the taking and placing of the steel bar 6 is facilitated, and the labor intensity of the operator is reduced. Figure 12 and the Figure 13As shown, the steel bar 6 is arranged obliquely, which facilitates the taking and placing.

[0053] In order to avoid the rotation of the inner frame 3 above the middle base 1, the collision of the adjacent two placing devices, a plurality of partitions 101 are vertically arranged above the middle base 1, and the partitions 101 are arranged on both sides of the first slide. The partitions 101 increase the depth of the first slide, and the top surface of the partition 101 is higher than the middle line of the inner frame 3, which clamps the placing device and avoids the rotation of the inner frame 3.

[0054] The side base 7 is connected to the outside of the middle base 1 in the direction of the movement of the placing device, and the second slide is concave in the top surface of the side base 7. The second slide is connected with the first slide, and the placing device can slide from the first slide to the inside of the second slide. After the placing device slides to the side base 7, the taking and placing operation of the steel bar 6 is started.

[0055] In order to synchronize the two operation modes and not interfere with each other, one side base 7 is used for discharging, and the other side base 7 is used for feeding.

[0056] A screw rod 11 is arranged in the first slide and the second slide, and the screw rod 11 is threadedly connected with the outer frame 2 of the placing device. The driving device 10 drives the rotation of the screw rod 11.

[0057] Therefore, during the taking and placing of the steel bar 6, the operator needs to go to the top of the side base 7. If the upper end of the second slide is always open, it will affect the walking of the operator and cause safety hazards. Therefore, a cover plate 8 is arranged above the second slide, and the top surface of the cover plate 8 is flush with the top surface of the side base 7. The cover plate 8 is hinged with the side base 7, and when the placing device needs to move to the side base 7, the corresponding cover plate 8 is turned open. As shown in the figure, it does not affect the movement of the placing device, and the other cover plates 8 are in a horizontal state, sealing the second slide and not affecting the walking of the operator. Figure 13

[0058] The turning of the cover plate 8 can be driven by a rotating motor or a rotating hydraulic motor, but this needs to increase the driving device and increase the cost. However, the function of the cover plate 8 and its turning is very simple, and the precision requirement is not high. Therefore, in this embodiment, the driving device is saved, and the turning of the cover plate 8 is connected with the placing device.

[0059] The parts for realizing the above functions are the opening block 5, and the end of the outer frame 2 of the placing device towards the side base 7 is provided with the opening block 5, which is arranged above the screw rod 11. When the placing device slides to the side base 7, the opening block 5 turns the cover plate 8 to make the cover plate 8 in a vertical state.

[0060] ​The side of the opening block 5 towards the cover plate 8 is provided with a first inclined surface 501 and a second inclined surface 502, which are arranged intersecting each other, and the lower intersection is below the bottom surface of the cover plate 8. When the opening block 5 hits the cover plate 8, the intersection line of the first inclined surface 501 and the second inclined surface 502 pushes the cover plate 8 to flip upwards until it is in a vertical state.

[0061] Since the opening block 5 is protrudingly arranged, if the opening block 5 is placed above the middle base 1, the length of the partition plate 101 and the middle base 1 will be increased, and the material cost will be increased. Therefore, in the embodiment, the opening block 5 is arranged inside the side base 7, and the end of the cover plate 8 towards the opening block 5 is provided with a notch 801. In the initial state, the opening block 5 is arranged inside the notch 801, which solves the problem and reduces the material and cost. At the same time, the notch 801 is arranged at the end, and it will not affect the walking of the operating personnel.

[0062] The side surface of the side base 7 is provided with a gear box, and the driving device 10 drives a plurality of screw rods 11 to rotate through the gear box. Through the control of the gear box, the driving force of the driving device 10 can be individually distributed to each screw rod 11, so as to realize the control of moving out a single or multiple placing devices to the side base 7.

[0063] The gear box comprises a box body 9, and the end of the screw rod 11 is coaxially and fixedly connected with a driven bevel gear 1101, which is arranged inside the box body 9.

[0064] The output shaft 1001 of the driving device 10 penetrates into the box body 9, and the output shaft 1001 is horizontally arranged and is provided with a plurality of sliding grooves 1002 arranged along the axial direction on the circumferential surface. A plurality of driving bevel gears 13 are rotatably arranged on the output shaft 1001, and the driving bevel gears 13 are in meshing connection with the driven bevel gears 1101.

[0065] The driving bevel gear 13 is provided with a through hole, and the hole wall of the through hole is provided with a spline groove 1301. The driving bevel gear 13 and the output shaft 1001 are provided with a connecting and disconnecting device 14, which can control the connection and disconnection of the driving bevel gear 13 and the output shaft 1001.

[0066] In the embodiment, the connecting and disconnecting device 14 comprises a support shaft 1401 and a spline shaft 1402 which are coaxially and fixedly connected, and the support shaft 1401 and the spline shaft 1402 are both sleeved on the output shaft 1001. The inner wall of the support shaft 1401 or the spline shaft 1402 is protrudingly provided with a sliding block 1403, and the sliding block 1403 is slidingly arranged in the sliding groove 1002. In this way, the connecting device 14 can only slide along the axial direction of the output shaft 1001, and the output shaft 1001 rotates to drive the connecting device 14 to rotate at any time.

[0067] When the driving bevel gear 13 is disconnected from the output shaft 1001, the support shaft 1401 is located between the driving bevel gear 13 and the output shaft 1001, and the spline shaft 1402 is located outside the driving bevel gear 3;

[0068] When the driving bevel gear 13 is connected to the output shaft 1001, the spline shaft 1402 is slid to the area between the driving bevel gear 13 and the output shaft 1001 through the sliding disconnecting device 14, and the spline shaft 1402 is inserted into the spline groove 1301, so that the driving bevel gear 13 is connected to the disconnecting device 14, and then connected to the output shaft 1001.

[0069] In order to control the sliding of the disconnecting device 14, a sleeve ring 15 is sleeved on the end of the spline shaft 1402 away from the support shaft 1401, and the sleeve ring 15 is rotatably connected to the spline shaft 1402. The upper and lower sides of the sleeve ring 15 are provided with connecting rods 1501, and the ends of the two connecting rods 1501 are connected to a push plate 1502. A first slide 901 is provided on the side wall of the box 9, and the push plate 1502 is slidably arranged in the first slide 901.

[0070] A second telescopic device 12 is fixed on the side wall of the box 9, and the telescopic rod of the second telescopic device 12 is connected to the push plate 1502. The telescopic rod of the second telescopic device 12 is extended, the disconnecting device 14 is pushed by the sleeve ring 15, the spline shaft 1402 is pushed into the spline groove 1301, and the connection between the driving bevel gear 13 and the output shaft 1001 is realized.
