Description

Technical Field

[0001] The utility model relates to the field of fluidizing rods, in particular to an online replacement device for fluidizing rods in a steel plate warehouse. Background Art

[0002] The fluidizing rod is a key tool for discharging materials from the steel plate warehouse. It is generally set at the guide cone of the steel plate warehouse and near the discharge port to play the role of homogenizing materials. The existing fluidizing rod is generally installed after the steel plate warehouse is built and before the materials are loaded. The intermediate replacement can only be replaced after the materials in the warehouse are unloaded. When there are materials, the fluidizing rod cannot be replaced. However, there is a problem. When there are materials in the warehouse, the fluidizing rod has aged after years of use. In particular, the external filter cloth is often damaged, which causes the fluidizing rod to return materials and eventually block the fluidizing rod. If most of the fluidizing rods in the warehouse are aged, it will seriously affect the discharge of the steel plate warehouse. If you need to wait for the materials in the warehouse to be unloaded before replacing the fluidizing rod, then before the materials are unloaded, the discharge of the steel plate warehouse will be greatly affected, and even the problem of difficulty in discharging will occur; what's more, the unloading time of the materials is uncertain, which also leads to the uncertainty of the time to replace the fluidizing rod. Therefore, when there are materials in the steel plate warehouse, the existing technology cannot replace the fluidizing rod in time. Utility Model Content

[0003] The existing fluidizing rods need to wait until the steel plate warehouse is emptied before they can be replaced. Before the steel plate warehouse is emptied, the discharge of the steel plate warehouse is greatly affected, and even the discharge problem occurs. The material discharge time is uncertain. Therefore, when there is powder in the warehouse, the existing technology cannot replace the fluidizing rod in time.

DETAILED DESCRIPTION

[0018] In order to clearly illustrate the technical features of the present invention, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0019] In addition, in the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0020] like Figure 1-2 As shown, an online replacement device for fluidizing rods in a steel plate warehouse comprises a fixing frame 1, a rotating chuck 5 and a drilling pipe 3. The fixing frame 1 has a horizontal support platform at the upper end thereof, which is used for operators and provides installation positions for other components. The height of the horizontal support platform of the fixing frame 1 is determined according to the position of the fluidizing rods set on the wall of the steel plate warehouse. The fixing frame 1 may be provided with a ladder to facilitate the staff to enter the horizontal support platform.

[0021] The fixing frame 1 is provided with a guide rail 2 , and the rotating chuck 5 has a connecting seat 501 , which is slidably arranged on the guide rail 2 , so that the rotating chuck 5 as a whole can move along the guide rail 2 .

[0022] The drilling tube 3 is clamped in the rotating chuck 5, which can drive the drilling tube 3 to rotate and feed the drilling tube 3 along the guide rail 2 (the feeding of the drilling tube 3 along the guide rail 2 can be achieved by manual operation). First, a circular opening of the drilling tube 3 is passed through the cutting part of the wall of the steel plate warehouse. The drilling tube 3 is aligned with the circular opening position and a channel is drilled near the bottom of the steel plate warehouse to place a new fluidizing rod. This channel is formed in the compacted powder at the bottom of the steel plate warehouse. Therefore, In order to reduce the difficulty of drilling during the drilling process of the drilling pipe 3, a cutter head assembly is provided at one end of the drilling pipe 3, and the cutter head assembly is arranged to extend out of this end face. The cutter head assembly first breaks the powder in the front, and then the other end of the drilling pipe 3 is connected to the negative pressure suction component 7, and the crushed powder is sucked out by the negative pressure suction component 7, so that a channel is formed inside the powder. After the channel is completed, the drilling pipe 3 is pulled out, and the rotating chuck 5 can remove the drilling pipe 3, and a new fluidizing rod is installed, and the new fluidizing rod is placed in the channel.

[0023] Furthermore, in order to adapt to the different angles of the guide cones of different steel plate warehouses, the fluidizing rod needs to be placed at different angles. One end of the guide rail 2 is hinged to the fixed frame 1 through a hinge seat, and a lifting component is hinged between the other end and the fixed frame 1. In the present embodiment, the lifting component adopts a telescopic cylinder 8, which can be an electric cylinder, an air cylinder or an oil cylinder, etc. The lifting component rises or falls to drive the height of the guide rail 2 at this end, while the height of the other end remains unchanged, so the angle of the guide rail 2 can be changed (it can be the angle relative to the horizontal plane, or it can be said to be the angle relative to the vertical plane). Different angles of the guide rail 2 mean that the drilling pipe 3 on the rotating chuck 5 will have different angles, which means that the angle of the drilled channel is different. After the fluidizing rod is placed, the angle of the fluidizing rod will also be different.

[0024] Further, in one embodiment, if Figure 3 As shown, the feeding of the above-mentioned rotating chuck 5 on the guide rail 2 can be driven in the following manner, that is, the connecting seat 501 is threadedly connected to the lead screw 10, one end of the lead screw 10 is connected to the motor 11 arranged at one end of the guide rail 2, and the motor 11 rotates forward and reversely, driving the lead screw 10 to rotate forward and reverse, thereby driving the rotating chuck 5 and the drilling pipe 3 thereon to feed forward and backward.

[0025] Furthermore, the above-mentioned rotating chuck 5 includes a chuck 503, which is in the shape of a long cylinder. The contact surface between the long cylinder-shaped chuck 503 and the drilled hole is large, thereby improving the stability of the drilled hole. The chuck 503 is arranged on the connecting seat 501 through a bearing 502. The outer periphery of the chuck 503 is provided with meshing teeth 504 along its periphery. The meshing teeth 504 mesh with the driving gear 6, and the driving gear 6 is connected to the motor reducer 9 arranged on the connecting seat 501.

[0026] Furthermore, the specific structure of the above-mentioned cutter head assembly includes three drill bits 4, and the three drill bits 4 are evenly spaced along the circumference of the drilling pipe 3. Each drill bit 4 is arranged along the axial direction of the drilling pipe 3 and extends out of the end face of the drilling pipe 3. The drill bit 4 extends out of the end face of the drilling pipe 3 to avoid the end face of the drilling pipe 3 from directly contacting with the powder and directly blocking the drilling pipe 3.

[0027] Furthermore, the negative pressure suction component 7 includes a vacuum pump 702 and a hose 701. The suction port of the vacuum pump 702 is connected to one end of the hose 701, and the other end of the hose 701 is detachably connected to the drilling pipe 3. The hose 701 and the drilling pipe 3 can be connected through an existing connector. When the drilling pipe 3 needs to be removed from the rotating chuck 5, the hose 701 and the drilling pipe 3 are disassembled to facilitate the removal of the drilling pipe 3.

[0028] The above-mentioned specific implementation manner cannot be used as a limitation on the protection scope of the present utility model. For those skilled in the art, any replacement, improvement or change made to the implementation manner of the present utility model falls within the protection scope of the present utility model.

[0029] The matters not described in detail in the present invention are all known technologies to those skilled in the art.
