Detailed implementation mode
[0027] Now, the present utility model will be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner. Therefore, they only show the components related to the present utility model. Directions and references (such as up, down, left, right, etc.) can only be used to assist in the description of the features in the drawings. Therefore, the following specific implementation modes are not adopted in a restrictive sense, and the scope of the claimed subject matter is only defined by the appended claims and their equivalent forms.
[0028] As Figure 1 and Figure 2 shown, a ladle cleaning mechanism for casting is the optimal embodiment of the present utility model. This mechanism is used to transfer and clean the ladle 3. The outer peripheral surface of the ladle 3 is provided with lifting lugs. In this embodiment, in order to achieve the automatic docking of the ladle 3 and the cleaning mechanism, the lifting lugs of the ladle 3 are hexagonal lifting lugs.
[0029] Specifically, this mechanism includes a transfer trolley 5 and a dust removal chamber 1. The bottom of the transfer trolley 5 has rollers, and the rollers are used to move the entire transfer trolley 5. The transfer trolley 5 is provided with a lifting mechanism, and the upper end surface of the lifting mechanism has a transfer platform. The transfer platform bears the ladle 3 and, when needed, the ladle 3 is lifted and lowered by the action of the lifting mechanism. In actual selection, the lifting mechanism can adopt but is not limited to a scissor-type lifting mechanism, etc. At the same time, in order to facilitate the transportation of the ladle 3, a number of conveying rollers can also be arranged at intervals on the transfer platform for transferring and supporting the ladle 3.
[0030] As Figure 7 shown, the front wall of the dust removal chamber 1 is provided with a door opening 11 for the transfer trolley 5 to drive in and park. The bottom of the dust removal chamber 1 is provided with a trolley track 8 along the traveling direction of the transfer trolley 5. The bottom of the transfer trolley 5 has rollers that cooperate with the trolley track 8. The height of the trolley track 8 is flush with the bottom ground of the dust removal chamber 1 to ensure the safety and stability of the transfer process.
[0031] As Figure 5 and Figure 6As shown in the figure, fixed columns 4 are symmetrically arranged on both sides corresponding to the parking positions of the transfer trolley 5 in the dust removal chamber 1. On the inner side surface of each fixed column 4 close to the fixed trolley, a tilting mechanism 6 is rotatably connected. The tilting mechanism 6 rotates at an angle relative to the horizontal plane under the drive of a power mechanism. The tilting mechanism 6 is internally provided with a clamping mechanism that cooperates with the lifting lugs of the ladle 3 and synchronously drives the ladle 3 to move.
[0032] The clamping mechanism includes a chuck 61, and an anti-dropping cover plate 63 is detachably provided on the chuck 61 through bolts and pins. Specifically, as Figure 3 shown, the chuck 61 is rotatably connected to the inner side surface of the fixed column 4. The chuck 61 is recessed up and down to form a fixed clamping groove 62 for the lifting lugs of the ladle 3 to fall and be clamped. The lower end surface of the lifting lug can be clamped in cooperation with the fixed clamping groove 62. The anti-dropping cover plate 63 is arranged at the upper end of the fixed clamping groove 62. One side of the anti-dropping cover plate 63 is hinged to the top of the chuck 61. After the lifting lug is clamped in the fixed clamping groove 62, the anti-dropping cover plate 63 rotates to cover the upper end surface of the fixed clamping groove 62, and the anti-dropping cover plate 63 is fixed to the upper end surface of the fixed clamping groove 62 through bolts and pins. At this time, the top of the lifting lug abuts against the lower end surface of the anti-dropping cover plate 63 for positioning. In this way, the lifting lug can be effectively positioned with the chuck 61. When the chuck 61 rotates, the ladle 3 is synchronously driven to tilt.
[0033] Specifically, the tilting power of the ladle 3 is provided by a speed reducer 2. The speed reducer 2 is fixed on the outer side surface of any one of the fixed columns 4. The output end of the speed reducer 2 is in transmission connection with the chuck 61 and drives the chuck 61 to rotate relative to the fixed column 4, and the tilting mechanism corresponding to the other fixed column 4 rotates passively. The operator can drive the chuck 61 and the ladle 3 to tilt by controlling the output of the speed reducer 2.
[0034] As Figure 2 shown, an observation port 12 is opened on the rear wall surface of the dust removal chamber 1. A blowpipe for the operator to hold and clean the ladle 3 is provided at the observation port 12. After the ladle 3 tilts, the operator can hold the blowpipe and use the observation port 12 of the dust removal chamber 1 to clean the ladle 3. The power cord 71 of the speed reducer 2 is led out and connected with an operation button 7. In actual use, for the convenience of observation and operation, the operation button 7 is arranged on the outer wall of the dust removal chamber 1 on the side of the observation port 12.
[0035] The debris generated by the ladle cleaning operation is collected and transported by the slag pot. Specifically, a transfer track is also provided at the bottom of the dust removal room 1, and a slag pot that moves along the transfer track is provided on the transfer track. When the ladle 3 is tilted to clean the slag, the slag pot moves along the transfer track to the bottom of the ladle 3 to receive the slag, so that during the ladle cleaning process, the cleaned debris falls into the slag pot, achieving the purpose of unified cleaning. After receiving the slag, the slag pot is transported out of the dust removal room 1 through the transfer track, which is more convenient for transportation and cleaning. In the actual cleaning operation, the slag pot can be manually pushed along the transfer track to the slag cleaning and material receiving position before the ladle 3 enters the dust removal room 1. After the cleaning operation of the ladle 3 is completed and the ladle 3 is transported out, it is manually pushed and transported out of the dust removal room 1. At the same time, the movement of the slag pot along the transfer track can also be designed with a remote control device, which can also prevent the operator from directly entering the dust removal room, further reducing the harm that the high temperature environment may cause to the operator.
[0036] The flue gas and dust generated by the ladle cleaning operation are collected and cleaned by the dust collector. Specifically, a dust removal duct 9 is provided on the top of the dust removal room 1, the lower end of the dust removal duct 9 is connected to the inside of the dust removal room 1, and the upper end of the dust removal duct 9 is connected to the dust collector. Through the coordinated arrangement of the dust removal duct 9 and the dust collector, during the ladle cleaning operation, the dust collector can collect a large amount of flue gas generated during the cleaning process. The front door opening 11 of the dust removal room 1 is open to facilitate the entry and exit of the transfer trolley 5 carrying the ladle 3, and at the same time, it can also provide sufficient wild wind volume for the dust collector to prevent the overflow of flue gas and dust, so as to achieve the purpose of rapid collection of flue gas and dust.
[0037] In terms of maintenance, a side door is opened on the wall of any one side of the side walls of the dust removal room 1 corresponding to the door opening 11, and the position of the side door is set corresponding to the installation position of the reducer 2, which is convenient for maintenance of the reducer 2.
[0038] When working:
[0039] The ladle 3 is placed on the transfer trolley 5 and driven into the dust removal room 1. The transfer trolley 5 lifts the ladle 3 to a certain height and then automatically docks with the tilting mechanism 6 on the inner side of the fixed column 4. The operator then controls the start and stop of the reducer 2 by controlling the operating button 7 of the reducer 2, thereby controlling the tilting angle of the steel. When the ladle 3 tilts 90°-120°, the ladle 3 tilts downward. The operator then uses the oxygen blowing pipe to clean the ladle 3 using the observation port 12 of the dust removal room 1. The slag pot below receives the cleaned debris and transports it out of the dust removal room 1. The dust collector on the top of the dust removal room 1 effectively collects the flue gas dust generated during the cleaning process.
[0040] A ladle cleaning mechanism designed in this way can solve problems such as low cleaning efficiency of the ladle 3, insecurity during the cleaning process, environmental pollution in the workshop, and harm to the human body in the high-temperature environment. The transfer trolley 5 carrying the ladle 3 is automatically docked with the ladle cleaning mechanism in the dust removal room 1, and then the mechanism automatically tilts the ladle 3. The dust collector can collect a large amount of flue gas generated during the cleaning process, avoiding harm to personnel in the high-temperature environment.
[0041] Inspired by the ideal embodiments of the present invention described above, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of this invention. The technical scope of this invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
