Description

Technical Field

[0001] The invention relates to the technical field of a slag cleaning method for a calcium carbide furnace aisle, and in particular to a slag cleaning method for aisle. Background Art

[0002] Aisle slag cleaning machine is a kind of equipment that replaces manual operation of aisle slag cleaning of calcium carbide furnace, realizes machine instead of man, applies near control wireless control, liberates operators from high temperature and high dust working environment, and further improves the safety level of on-site work. It is an integrated operation machine that realizes aisle slag crushing and cleaning, and the main function of the aisle track slag cleaning machine industry of calcium carbide furnace is to clean the slag generated in the production process of calcium carbide furnace to ensure the smooth operation of the production line. The products of this industry mainly include various types of slag cleaning machinery, such as single excavator, single breaker, etc., which have single functions, large equipment volume, not suitable for operation at the operation site, and cannot flexibly and comprehensively carry out slag cleaning work in front of the furnace. In view of this, our company has designed a device that integrates crushing, excavation and shoveling operations. However, due to the large number of equipment functions, when actually operating and using it, the staff needs to follow the operating steps in sequence. If there is an operating error, it will cause collision problems between some structures of the equipment. Summary of the invention

[0003] In order to solve the problem that the operation steps of the above-mentioned integrated equipment are complicated and structural collision is likely to occur if the operation is not performed according to the steps, the present invention provides an aisle slag cleaning method.

[0004] The technical solution of the present invention is as follows:

[0005] A slag cleaning machine for an aisle comprises a mobile carrier, a rotary drive frame is arranged above the mobile carrier, and the rotary drive frame is rotatably connected to a first support arm, an end of the first support arm away from the mobile carrier is connected to a second support arm, and a bucket and a rock drilling mechanism are arranged at an end of the second support arm away from the mobile carrier, and the bucket and the rock drilling mechanism are driven by a first driver and a second driver respectively and move relative to the second support arm, the bucket and the rock drilling mechanism are located in the same vertical plane, and the working positions of the bucket and the rock drilling mechanism are the same, and the states are switched by the first driver and the second driver;

[0006] A shovel bucket is also provided at one end of the mobile vehicle close to the digging bucket, and the shovel bucket is arranged on a guide rail at the front end of the mobile vehicle, and the length direction of the guide rail is arranged perpendicular to the moving direction of the mobile vehicle.

[0007] By integrating other functional structures on the mobile carrier, all operations of slag cleaning in the calcium carbide furnace aisle can be completed without changing equipment.

[0008] In order to adjust the working position, the rotary drive frame can rotate in a horizontal plane relative to the mobile carrier, the first support arm can rotate in a vertical plane relative to the rotary drive frame, and the second support arm can rotate in a vertical plane relative to the first support arm.

[0009] A method for cleaning slag in an aisle, using the above-mentioned aisle cleaning machine, and comprising the following steps:

[0010] S1. Move the aisle slag cleaning machine to the aisle operation position of the calcium carbide furnace by using a mobile carrier;

[0011] S2, control the bucket to retract, then control the rock drilling mechanism to perform crushing operation at the working position, and after the crushing operation is completed, control the rock drilling mechanism to retract and control the bucket to perform the operation;

[0012] S3, moving the bucket to the corresponding position of the digging bucket;

[0013] S4. Place the aisle debris into the bucket through the digging bucket.

[0014] Through the above method, all aisle slag cleaning operations can be completed by a single device.

[0015] In order to avoid structural collision, in step S2, the stroke range of the first driver is preset to (m, n), and there is a preset value v within the stroke range. After the extension stroke of the first driver exceeds the preset value v, the second driver can be retracted to the limit position. In this way, it is possible to achieve the automatic retraction of the second driver by the device during the extension operation of the first driver, thereby achieving the structural switching of the function, avoiding the conventional mandatory operation requirement of retracting the second driver first and then extending the first driver.

[0016] As a preferred solution, in step S2, the stroke range of the second driver is preset to (j, k), and there is a preset value l within the stroke range. After the extended stroke of the second driver exceeds the preset value l, the first driver can be retracted to the extreme position.

[0017] In order to simplify the operation requirements, in step S3, angle encoders are respectively set at the positions of the rotating shafts between the mobile carrier and the rotary drive frame, the rotary drive frame and the first support arm, and the first support arm and the second support arm, and the position of the second support arm away from the end of the mobile carrier is obtained according to the values ​​of the above angle encoders;

[0018] The bucket coordinate point is obtained according to the intersection of the vertical plane where the position of the second support arm away from the end of the mobile carrier and the rotary drive frame connection line and the vertical plane where the guide rail where the bucket is located, and the bucket center point is controlled to move to the bucket coordinate point.

[0019] Set the position of the bucket to correspond to the digging bucket. In this way, you do not need to concentrate on controlling the position of the bucket during the digging process.

[0020] In order to avoid ineffective movement of the bucket, the bucket can only move after the first driver extends the stroke beyond a preset value l.

[0021] As a preferred solution, the bucket and rock drilling mechanism can only operate at the front end of the mobile vehicle, which is more suitable for operation requirements in a limited environment.

[0022] In order to facilitate the adjustment of the bucket pitch angle, the guide rail can rotate on a vertical plane, and an angle encoder is arranged at the rotating shaft.

[0023] In order to prevent the operator from being distracted from controlling the bucket, the guide rail can be rotated downward after the first driver extends a stroke exceeding a preset value l, and can be rotated upward after the first driver extends a stroke less than a preset value l.

[0024] The beneficial effects of the present invention are as follows: the present invention is an aisle slag cleaning machine and a method of use. By setting up an aisle slag cleaning machine that integrates all functions, it is possible to operate in the confined environment of the calcium carbide furnace aisle, thereby avoiding inefficient operations caused by frequent switching of operating equipment, and a special method of use is designed for the above-mentioned integrated equipment. Under normal circumstances, when performing crushing operations, the bucket needs to be retracted, so the conventional operation method is to first control the retraction of the bucket and then control the extension of the rock drilling mechanism. If the operations are not performed in sequence, it is easy to cause collisions between structures. The present device can automatically control the retraction of the bucket during the process of controlling the extension of the rock drilling mechanism. Conversely, when controlling the extension of the bucket, the retraction of the rock drilling mechanism can be automatically controlled, thereby avoiding structural damage and being more convenient. During excavation operations, the bucket can move synchronously with the bucket, thereby avoiding distraction in controlling the bucket. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] like Figure 1 The aisle slag cleaning machine shown in the figure includes a mobile carrier 1, the mobile carrier 1 is movable, and a rotary driving frame 2 is arranged above the mobile carrier 1, the rotary driving frame 2 is arranged on the fixed production of the mobile carrier 1, and is connected thereto by a vertical pin shaft, and then the output end of the rotary oil cylinder is connected to realize the rotation relative to the mobile carrier 1, and the rotary driving frame 2 is rotatably connected to the first support arm 3, the rotary driving frame 2 and the first support arm 3 are rotatably connected by a horizontally arranged pin shaft and an oil cylinder is arranged therebetween, and the first support arm 3 can be driven to rotate by extending and contracting the oil cylinder, and finally the end of the first support arm 3 away from the mobile carrier 1 is connected to the second support arm 4, and correspondingly, the second support arm 4 can be driven by the connection method of the pin shaft and the oil cylinder. It should be noted that in order to realize the working function The bucket 6 and the rock drilling mechanism 5 are respectively driven by the first driver 8 and the second driver 9 and move relative to the second support arm 4, in that the bucket 6 is rotatably connected to the second support arm 4, and the end is also rotatably connected to the output end of the first driver 8. In the above manner, the excavation action can be achieved by driving the first driver 8. Correspondingly, the rock drilling mechanism 5 is also the same, and the bucket 6 and the rock drilling mechanism 5 are located in the same vertical plane, and the working positions of the bucket 6 and the rock drilling mechanism 5 are the same. In this way, when controlling the switching of the operating mechanism, there is no need to adjust the position, but the state can be directly switched by the first driver 8 and the second driver 9, and different operating mechanisms can be switched to operate in the same operating position.

[0032] In order to collect and shovel away the debris, a bucket 7 is provided at one end of the mobile vehicle 1 close to the bucket 6, and the bucket 7 is arranged on a guide rail at the front end of the mobile vehicle 1, and the length direction of the guide rail is arranged perpendicular to the moving direction of the mobile vehicle 1, that is, the bucket 7 can move perpendicular to the traveling direction of the mobile vehicle 1, and when in use, the position can be adjusted as required to ensure that the debris from the bucket is quickly received. The above structure is hidden. By integrating other functional structures on the mobile vehicle 1, all operations of cleaning the slag in the aisle of the calcium carbide furnace can be completed without changing the equipment, which is suitable for the needs of operations in such a limited environment.

[0033] It should be noted that in the above structure, in order to achieve the adjustment of the working position, the rotary drive frame 2 can rotate in a horizontal plane relative to the mobile carrier 1, and the first support arm 3 can rotate in a vertical plane relative to the rotary drive frame 2, and the second support arm 4 can rotate in a vertical plane relative to the first support arm 3, and the first support arm 3 and the second support arm 4 are located in the same vertical plane. Through the above method, the position of the bucket and the rock drilling mechanism can be adjusted, and the above adjustment can ensure that the bucket and the rock drilling mechanism can perform slag cleaning operations at any position in the aisle.

[0034] At the same time, a method for cleaning slag in an aisle is also disclosed, which uses the above-mentioned aisle cleaning machine and includes the following steps:

[0035] S1. Move the aisle slag cleaning machine to the aisle operation position of the calcium carbide furnace by using the mobile carrier 1. The mobile carrier 1 can be a crawler vehicle, and its moving method will not be described in detail;

[0036] S2, control the bucket 6 to retract, then control the rock drilling mechanism 5 to perform crushing operation at the working position, and after the crushing operation is completed, control the rock drilling mechanism 5 to retract and control the bucket 6 to perform the operation;

[0037] The above steps are conventional operating methods, so the staff needs to first control the bucket 6 to retract, and then extend the rock drilling mechanism 5. If the steps are wrong, it will cause problems with the above structure. Therefore, in order to avoid structural collision, in step S2, the stroke range of the first driver 8 is preset to (m, n), and there is a preset value v within the stroke range. After the extension stroke of the first driver 8 exceeds the preset value v, the second driver 9 can be retracted to the extreme position, and the retraction of the above-mentioned second driver 9 is directly controlled by the control terminal. That is to say, through this method, it is possible to achieve the automatic retraction of the second driver 9 through the equipment during the extension operation of the first driver 8, thereby realizing the structural switching of the function, avoiding the conventional mandatory operation requirement of first retracting the second driver 9 and then extending the first driver 8, and the above method can significantly reduce the difficulty of operation and ensure the normal operation of the equipment.

[0038] Correspondingly, in step S2, the stroke range of the second driver 9 is preset to (j, k), and there is a preset value l within the stroke range. After the extended stroke of the second driver 9 exceeds the preset value l, the first driver 8 can be retracted to the extreme position, which is the same as the above method. In this way, the operator can select the corresponding operating mechanism according to the needs without considering the use steps. Instead, the operator can directly operate and drive whatever operating mechanism is needed. The avoidance action of the other operating mechanism is automatically controlled by the main control terminal.

[0039] Moreover, within the formation range, not only the position of the operating device needs to be switched, but also the angle needs to be adjusted during its operation phase. Therefore, within the (l, k) interval, the operating mechanism can be allowed to be freely controlled.

[0040] S3, move bucket 7 to the corresponding position of bucket 6;

[0041] Under normal circumstances, after the bucket 6 completes the excavation operation, the slag needs to be placed in the bucket position. For this purpose, the staff needs to move the bucket 6 and align the bucket and complete the transfer of the slag. In order to simplify the operation requirements, in step S3, angle encoders are respectively set at the rotating shaft positions of the mobile carrier 1 and the rotary drive frame 2, the rotary drive frame 2 and the first support arm 3, and the first support arm 3 and the second support arm 4, and the position of the second support arm 4 away from the end of the mobile carrier 1 is obtained according to the value of the above-mentioned angle encoder. Since the position of the mobile carrier 1 and the guide rail is constant, the coordinate position of the bucket 6 relative to the mobile carrier 1 can be calculated according to the values ​​of the above-mentioned multiple angle encoders. Furthermore, according to the The coordinate point of bucket 7 is obtained by the intersection of the vertical plane where the two support arms 4 are located away from the end of the mobile carrier 1 and the vertical plane where the line connecting the rotary drive frame 2 is located and the vertical plane where the guide rail of the bucket 6 is located, and the bucket 7 is controlled to move to the coordinate point of bucket 7. In the above manner, bucket 7 can be automatically moved, and the above movement is synchronized with bucket 6. Therefore, when in use, no matter where the bucket 6 is moved to perform operations, the bucket 6 will move accordingly. In the above manner, the operator can avoid operating the bucket 7 alone, which can simplify the operating difficulty of the above equipment. In the above manner, the problem that the existing equipment requires the operator to independently operate the moving bucket 6 to the specified position can be solved. And the position of bucket 7 is set to correspond to bucket 6. In this way, there is no need to be distracted to control the position of bucket 7 during the excavation process. In addition, in order to avoid invalid movement of bucket 7, the bucket 7 can only move after the first driver 8 extends the stroke beyond the preset value l. That is to say, only when the excavation operation is performed, the bucket 7 will trigger its function of tracking the position of bucket 6.

[0042] S4. Place the aisle debris into the bucket 7 through the bucket 6.

[0043] Through the above method, all aisle slag cleaning operations can be completed by a single device.

[0044] like Figure 2 As shown, as a preferred solution, the bucket 6 and the rock drilling mechanism 5 can only operate at the front end of the mobile vehicle 1. It is more suitable for operation requirements in a limited environment.

[0045] Finally, in order to solve the need for the operator to manually control the pitch of the bucket 7 and automatically adjust the pitch angle of the bucket 7, the guide rail can rotate on a vertical plane, and an angle encoder is provided at the rotation axis. In order to prevent the operator from being distracted from controlling the bucket 7, the guide rail can rotate downward after the first driver 8 extends beyond a preset value 1, and can rotate upward after the first driver 8 extends less than a preset value 1. An angle encoder is provided at the rotating shaft of the guide rail, and a threshold value x is set for the angle encoder of the bucket 6 at the second support arm 4. The main control terminal records the number y of times the bucket 6 reaches the threshold value x at the second support arm 4, and the maximum angle of the guide rail downward rotation is controlled by the number y. A threshold value p is also set for this angle. When the downward rotation angle is less than the threshold value p, the bucket 7 no longer rotates downward. The purpose of this method is to solve the problem of debris stored in the bucket 7. Each time debris is transferred to the bucket 7 through the bucket 6, the volume of the bucket will become smaller. Accordingly, it is necessary to avoid flipping downward to prevent the debris from falling. Accordingly, the problem of requiring the operator to manually control the bucket 7 to flip upward can be solved by the above method.
