Description

Technical Field

[0001] The invention relates to the technical field of cement warehouse cleaning, and in particular to a cement warehouse cleaning machine. Background Art

[0002] In the process of cement production or storage, cement silos (also called cement tanks) are widely used because of their large storage capacity, safe storage, small footprint, no moving parts in the silo, one-time construction without special maintenance, and long service life. Since cement is a powder, under the influence of moisture, climate, temperature difference and other conditions, it is inevitable that a layer of attachments will condense and stick on the inner surface of the entire silo wall. These attachments become thicker and thicker with the passage of time, which will not only cause the volume of the cement silo to become smaller, but also fall off by themselves to become blocks or flakes of different sizes mixed in the cement powder. In mild cases, the feeder is often blocked, and in severe cases, the silo hopper will be arched and the material cannot be discharged, resulting in material shortage and production suspension. Therefore, it is necessary to clear the silo regularly.

[0003] At present, there are two main methods for clearing cement silos. One is manual cleaning, which is inefficient, time-consuming and labor-intensive, and prone to safety accidents. The other is mechanical cleaning, which is efficient and safe and has been gradually promoted and applied. However, during use, the existing cement silo cleaning equipment usually uses a lifting rope to adjust the lifting mechanism, which is prone to vibration and swing, and is not stable enough. Especially when placed near the bottom of the cement silo, the shaking is more severe due to the long distance between the cleaning mechanism and the lifting point, which is not conducive to the normal operation of the cleaning mechanism and affects the cleaning efficiency.

The cantilever 31 is connected to the bottom of the connecting column 162. The cantilever 31 is connected to a group of steel cable members 32 on both sides of the connecting column 162. The top of the steel cable member 32 is connected to the bottom of the receiving beam 12, and the bottom of the steel cable member 32 is connected to the cantilever 31. The wall cleaning machine 33 is installed on one side of the cantilever 31, the level 34 is installed in the middle of the cantilever 31, and the balance assembly 35 is installed on the other side of the cantilever 31. The wall cleaning machine 33 is used to clean the inner wall 200 of the cement silo. The balance assembly 35 is connected to the level 34 for communication. The balance assembly 35 is used to balance the wall cleaning machine 33 according to the horizontal data detected by the level 34. ;

[0022] The main beam 11 includes more than two short beams 111, and the two short beams 111 are connected end to end by bolts 112. Figure 1 As shown, the main beam 11 includes two short beams 111, the bottom of the first short beam 111 is connected to the top of the second short beam 111 by bolts 112, and the bottom of the second short beam 111 is connected to the top of the receiving beam 12 by bolts 112. A set of support components 14 are respectively installed in front and behind the receiving beam 12. Under the action of the driving component 15, the support arms 143 of the two sets of support components 14 are unfolded forward and backward along the third direction Z to the inner wall 200 of the cement silo until the support rollers 148 abut against the inner wall 200 of the cement silo. Among them, the driving component 15 needs to drive the moving screws 141 of the two sets of support components 14 to rotate synchronously. At the same time, the support cylinder 147 can be used to ensure that the support rollers 148 of the two sets of support components 14 can abut against the inner wall 200 of the cement silo. A rotating motor 161 is installed on the inner wall of the bottom of the supporting beam 12, and the output end of the rotating motor 161 is connected to the connecting column 162. Therefore, one end of the connecting column 162 extends into the supporting beam 12 and is connected to the rotating motor 161, and the other end of the connecting column 162 is connected to the middle part of the top of the cantilever 31. The other end of the connecting column 162 can be detachably connected to the middle part of the top of the cantilever 31 through a connecting fastener.

[0023] The guide frame 22 is located in the middle of the support bracket 21. The guide frame 22 is hollow inside and is sleeved outside the main beam 11, that is, the main beam 11 passes through the guide frame 22. Optionally, mounting plates 25 are fixedly installed on both sides of the guide frame 22, and the mounting plates 25 are used to install the servo motor 23. The output shaft of the servo motor 23 is connected to the pin on the corresponding lifting gear 24 through a coupling.

[0024] In addition to being connected to the cantilever 31 through the connecting column 162, the connection is also strengthened by the steel cable member 32. The cantilever 31 is connected to a group of steel cable members 32 on both sides of the connecting column 162. A group of steel cable members 32 can have multiple steel cables or a single steel cable. In some embodiments, a sleeve 121 is provided at the bottom end of the receiving beam 12, and a collar 122 is rotatably connected to the outer periphery of the sleeve 121 through a bearing. Multiple steel cables are fixedly connected to both sides of the collar 122, and the bottom of the steel cable is fixedly connected to the middle of the top of the cantilever 31.

[0025] Since the wall cleaning machine 33 will cause the gravity of the cantilever 31 to shift when in use, the wall cleaning machine 33 cannot clean the inner wall 200 of the cement silo well. Therefore, in order to ensure the balance of the cantilever 31 and the normal use of the wall cleaning machine 33, a balancing component 35 cooperating with the wall cleaning machine 33 is provided on the other side of the cantilever 31. The balancing component 35 balances the wall cleaning machine 33 through the horizontal data detected by the level meter 34. Among them, the wall cleaning machine 33 can be an existing wall cleaning device.

[0026] The technical solution of the present application is to install the lifting gear 24 by setting the supporting bracket 21 and the guide frame 22. The lifting gear 24 cooperates with the tooth plate 13 of the main beam 11 under the drive of the servo motor 23, so that the main beam 11 can be stably raised or lowered along the first direction X. Then the wall cleaning machine 33 on the cantilever 31 can be adjusted stably and quickly, effectively avoiding the problem of poor stability of traditional rope lifting, and greatly improving the stability of the lifting of the overall equipment. In addition, under the action of the driving component 15, the movable screw rod 141 can be rotated, so that the first slider 142 drives the push rod 146 to move downward, and when the push rod 146 moves downward, the corresponding support arm 143 can be pushed outward, so that the support roller 148 can support the cement depot cleaning machine 100 against the inner wall 200 of the cement depot under the action of the support cylinder 147, avoiding the phenomenon of shaking left and right, and then when the wall cleaning machine 33 is working, it maintains a stable state, avoiding the influence on the normal operation of the wall cleaning machine 33, and greatly improving the cleaning efficiency.

[0027] In some embodiments, the cement depot cleaning machine 100 further includes a control device, which is respectively connected to the main beam device 1, the supporting device 2, and the wall cleaning device 3. The operation of the cement depot cleaning machine 100 can be flexibly controlled by the control device. In other embodiments, the control device can also be connected to an external host computer, which is located outside the cement depot, and the staff can control the control device through the external host computer.

[0028] like Figure 6 and Figure 7As shown, the balancing assembly 35 includes a first linear module 350 and a first counterweight 351. The first linear module 350 extends along the second direction Y and is installed at the bottom of the cantilever 31. The first counterweight 351 is installed on the slider of the first linear module 350. The first linear module 350 is communicated with the control device. The control device is used to control the first counterweight 351 to move left or right along the second direction Y according to the horizontal data detected by the level meter 34 to balance the wall cleaning machine 33.

[0029] The first linear module 350 can be an existing linear module, which converts rotational motion into linear motion. For example: a screw linear module, a synchronous belt linear module or a pneumatic linear module. Under the action of the first linear module 350, the first counterweight block 351 can be moved along the second direction Y, and the wall cleaning machine 33 can be balanced by changing the position of the first counterweight block 351 on the cantilever 31. Therefore, the first linear module 350 is connected to the control device, and the control device controls the first counterweight block 351 to move along the second direction Y to balance the wall cleaning machine 33 according to the horizontal data detected by the level meter 34.

[0030] like Figure 8 As shown, the balancing assembly 35 also includes an external water tank 352, an inlet pump 353, an inlet pipe 354, a balancing water tank 355, an outlet pump 356 and an outlet pipe 357; the external water tank 352 is installed on the top of the cement storage, and the inlet pump 353 is installed at the bottom of the external water tank 352. The outlet of the inlet pump 353 is connected to the inlet of the balancing water tank 355 through the inlet pipe 354. The balancing water tank 355 is installed on the other side of the cantilever 31. On one side, an outlet water pump 356 is installed at the bottom of the balancing water tank 355. The water outlet of the outlet water pump 356 is connected to the water inlet of the external water tank 352 through an outlet pipe 357. The inlet water pump 353 and the outlet water pump 356 are both communicated with the control device. The control device is used to control the operation of the inlet water pump 353 or the outlet water pump 356 according to the level data detected by the spirit level 34, and the balancing water tank 355 takes in water or discharges water to balance the wall cleaning machine 33.

[0031] The external water tank 352 cooperates with the balancing water tank 355 to control the water volume in the balancing water tank 355, and balances the wall cleaning machine 33 by changing the weight of the balancing water tank 355. Specifically, the water inlet pump 353 can be used to control the water inlet of the balancing water tank 355, and the water outlet pump 356 can be used to control the water outlet of the balancing water tank 355.

[0032] like Fig. 9 and Fig.10As shown, the balancing assembly 35 also includes a second counterweight block 358 and two groups of second linear modules 359. The second counterweight block 358 is installed on the other side of the cantilever 31. A group of second linear modules 359 are installed on the top of each side of the connecting column 162 of the cantilever 31. The second linear modules 359 are extended along the second direction Y. The bottom of the steel cable member 32 is connected to the cantilever 31 through the second linear module 359. The second linear module 359 is communicatively connected to the control device. The control device is used to control the steel cable member 32 to move left or right along the second direction Y according to the horizontal data detected by the spirit level 34 to balance the wall cleaning machine 33.

[0033] The second linear module 359 can be an existing linear module that converts rotational motion into linear motion. For example: a screw linear module, a synchronous belt linear module or a pneumatic linear module. Under the action of the second linear module 359, the corresponding steel cable member 32 can be moved along the second direction Y, and the wall cleaning machine 33 can be balanced by changing the position of the steel cable member 32 on the cantilever 31. In some embodiments, a set of second linear modules 359 can be installed only above the side where the second counterweight block 358 is located, and the wall cleaning machine 33 can be balanced by only changing the gravity of the second counterweight block 358 on the opposite side of the wall cleaning machine 33.

[0034] like Fig.11 As shown, the support assembly 14 also includes a position sensor 1491, which is installed on the top of the support arm 143. The position sensor 1491 is communicated with the support cylinder 147. The support cylinder 147 is used to extend or contract according to the position data of the support roller 148 and the inner wall 200 of the cement storage detected by the position sensor 1491, so that the support roller 148 abuts against the inner wall 200 of the cement storage.

[0035] In actual use, one of the support rollers 148 may abut against the inner wall 200 of the cement silo, while the other support roller 148 may not abut against the inner wall 200 of the cement silo. Therefore, in order to ensure the support performance of the support assembly 14, a position sensor 1491 is provided. The position sensor 1491 is a device that can sense the position of an object and convert it into an electrical signal output. Therefore, the support cylinder 147 can be controlled to extend or contract according to the position data of the support roller 148 and the inner wall 200 of the cement silo detected by the position sensor 1491, so that the support roller 148 abuts against the inner wall 200 of the cement silo to play a supporting role.

[0036] like Fig.12As shown, the support assembly 14 also includes a camera 1492, which is installed on the top of the support arm 143. The camera 1492 is communicated with the support cylinder 147. The support cylinder 147 is used to extend or contract according to the image data of the inner wall 200 of the cement storage tank taken by the camera 1492, so that the support roller 148 abuts against the inner wall 200 of the cement storage tank.

[0037] The position sensor 1491 may also be replaced by a camera 1492, which feeds back information via graphical data. In some embodiments, the position sensor 1491 may also be replaced by an infrared sensor.

[0039] The movable lead screw 141 can be directly driven to rotate by the first drive motor 151 . One first drive motor 151 corresponds to a group of movable lead screws 141 of the support assembly 14 . Therefore, it is necessary to ensure that the two first drive motors 151 run synchronously.

[0040] like Figure 5 and Fig.14 As shown, the driving assembly 15 also includes a second driving motor 152, a driving gear 153, two transmission gears 154 and two driven gears 155. The second driving motor 152 is installed on the inner side of the top of the supporting beam 12, and the output end of the second driving motor 152 is connected to the driving gear 153. The front end and the rear end of the driving gear 153 are respectively connected to the driven gear 155 through the transmission gear 154. One driven gear 155 corresponds to one moving screw rod 141, and the driven gear 155 is installed on the top of the moving screw rod 141.

Specifically, the driving assembly 15 also includes a horizontal plate 156 fixed inside the receiving beam 12, the top of the horizontal plate 156 is rotatably connected with a driving gear 153, the top of the driving gear 153 is fixedly connected to the output end of the second driving motor 152, the front end and the rear end of the driving gear 153 are both provided with a driven gear 155, and the driving gear 153 and the corresponding driven gear 155 are transmission-connected by a transmission gear 154. Among them, the front end and the rear end of the receiving beam 12 are both provided with openings 123 at the corresponding positions of the driven gear 155, and one end of the driven gear 155 passes through the opening 123 and is meshed and connected with the corresponding transmission gear 154.

[0042] The working principle of a cement depot cleaning machine 100 is as follows: First, a top opening is opened in the middle of the top of the cement depot, and the support bracket 21 and the guide frame 22 are installed on the top of the cement depot, and the guide frame 22 is located at the top opening. Secondly, the main beam 11 passes through the guide frame 22 and extends to the inside of the cement depot, and the structures such as the receiving beam 12, the balance component 35 and the support component 14 are assembled, and debugging and testing are performed after the assembly is completed. Thirdly, the driving component 15 is started, and the moving screw 141 rotates under the action of the driving component 15. During the rotation of the screw, the first slider 142 can drive the push rod 146 to move downward along the first slide rail 140 along the first direction X. When moving downward, the corresponding support arm 143 can be pushed outward, so that the support roller 148 can support the cement depot cleaning machine 100 against the inner wall 200 of the cement depot under the action of the support cylinder 147, so as to avoid the whole device from shaking left and right. After the support and fixation are completed, the servo motor 23 is started, and the servo motor 23 drives the corresponding lifting gear 24. The lifting gear 24 cooperates with the toothed plate 13, so that the main beam 11 can stably lower the wall cleaning machine 33 to the specified position. Finally, when it is lowered to the specified position, the wall cleaning machine 33 starts to work and cleans the inner wall 200 of the cement silo. During the cleaning process, the rotating motor 161 can drive the cantilever 31 to rotate with the cooperation of the mounting seat. At the same time, the balancing assembly 35 can ensure the stability of the wall cleaning machine 33 according to the level meter 34, so that the wall cleaning machine 33 can operate stably. When the wall cleaning machine 33 has cleaned a circle of the inner wall 200 of the cement silo, the servo motor 23 is started again to control the wall cleaning machine 33 to stably descend until the wall cleaning is completed.
