Description

Technical Field

[0001] This invention relates to the technical field of rock chisels and hammers, specifically to an intelligent rock chisel hammer. Background Technology

[0002] Rock breaking involves using mechanical equipment or hand tools to break or split rocks through hammering, impact, or drilling to facilitate subsequent construction or mining operations. Rock drills are crucial tools in rock breaking, and their selection and use directly impact efficiency and safety. When choosing a rock drill, it is necessary to comprehensively consider factors such as rock type, construction environment, and the object being drilled, selecting the appropriate type and technical parameters.

[0003] When using a chisel hammer, the impact rock drilling method can be used, which utilizes the impact force acting on the chisel hammer to make the cutting edge of the chisel hammer cut into the rock and break it.

[0004] Through extensive research and reference, we have found that many chisel hammers have been developed. For example, existing technologies include chisel hammers disclosed in publication numbers CN102434089A, CN115711827A, CN108356766A, CN109723376A, CN108381466A, and CN104389329A. These generally include a hammer body and a power source that drives the hammer body to move. The power source moves the hammer body to the target position and limits the movement of the hammer body.

[0005] However, existing hammer technology does not limit the impact pressure during hammer striking, resulting in low hammer striking efficiency. Summary of the Invention

[0006] The purpose of this invention is to improve chiseling efficiency. In view of the above-mentioned shortcomings, an intelligent rock chiseling tiger head hammer is proposed.

[0024]

[0025]

[0026] Where YL is the maximum impact factor of the hammer, ky is the rock compressive strength reference index, and bf is the rock treatment index. bf has the following values: bf = 2 or bf = 3.

[0027] A is a reference index for rock type. A can take the following values: A = 2, A = 4, or A = 6. When A = 2, the rock type is sedimentary rock; when A = 4, the rock type is igneous rock; and when A = 6, the rock type is metamorphic rock. max Ku represents the maximum vertical length of the rock. max Let lx be the maximum horizontal length of the rock, B be the total number of cracks on the rock surface, and lx be the maximum value of the horizontal length of the rock. b Let be the length of the b-th rock fissure.

The adjustment submodule adjusts the movement mode of the chisel hammer to chisel the rock as quickly as possible, while also protecting the chisel hammer and extending its service life.

[0042] 2. After each impact, the chisel hammer needs to be adjusted to rotate a certain angle before the next impact to change the position of the chisel hammer's edge and achieve a better chiseling effect. Therefore, the rotation angle of the chisel hammer is obtained through the control module, and the rotation angle of the chisel hammer is strictly controlled to reduce the situation where the chisel hammer rotates too much, and at the same time, it can reduce the situation where the rotation angle of the chisel hammer is too small, which reduces the chiseling effect.

[0043] 3.

[0049] Example 1: This example provides an intelligent rock chisel hammer, combined with... Figure 1 and Figure 2 As shown.

[0050] An intelligent rock chisel tiger-head hammer includes a data storage module, a detection module, a control module, and a chiseling module, wherein the data storage module, the detection module, and the chiseling module are all communicatively connected to the control module;

[0051] The data storage module is used to store information such as rock processing index, impact speed of the hammer, impact frequency of the hammer, feed rate of the hammer, total service life of the hammer, total number of repairs of the hammer, and rock type reference index, and transmits it to the control module.

[0052] The detection module is used to detect and obtain the hardness value of the hammer, the hardness value of the z-th rock test, the maximum angle of the rock surface tip during the y-th test, the contact area between the hammer and the rock, the maximum length of the rock in the vertical direction, the maximum length of the rock in the horizontal direction, the total number of cracks on the rock surface, and the length of the b-th rock crack, and transmits this information to the control module; the hardness value can be measured by a hardness measuring instrument or an ultrasonic hardness tester.

[0053] The control module calculates the total number of rock surface tip detections based on the maximum horizontal length of the rock, calculates the total number of rock hardness detections based on the maximum vertical length of the rock, calculates the rock compressive strength reference index and the maximum impact factor of the chisel hammer based on relevant information, calculates the maximum impact pressure selection function of the chisel hammer based on the maximum impact factor of the chisel hammer, and transmits the maximum impact pressure information of the chisel hammer to the chisel module.

[0054] The chiseling module includes an adjustment submodule and a chisel hammer that are connected in communication. The adjustment submodule is connected in communication with the control module. The adjustment submodule receives information about the maximum impact pressure of the chisel hammer and limits the movement mode of the chisel hammer based on the information about the maximum impact pressure of the chisel hammer.

[0055] Optionally, the detection module includes a hardness detection submodule and a visual detection submodule, both of which are communicatively connected to the control module; the visual detection submodule includes a first camera module fixedly connected to the chisel hammer and a second camera module that takes pictures around the rock.

[0056] The hardness detection submodule is used to detect and obtain the hardness value of the chisel hammer and the hardness value of the z-th rock test, and transmit them to the control module.

[0057] The first camera module is used to capture the angle formed between the initial front half of the hammer and the front half of the hammer after the last impact, and transmit it to the control module;

[0058] The second camera module is used to detect and obtain the maximum value of the angle during the y-th rock surface tip detection, the contact area between the hammer and the rock, the maximum value of the rock's vertical length, the maximum value of the rock's horizontal length, the total number of cracks on the rock surface, and the length of the b-th rock crack, and transmit this information to the control module. In this embodiment, the angle during rock surface tip detection refers to the angle obtained by the second camera module in the captured image of the rock tip, which is the angle formed vertically by the extensions of the left and right boundary lines of the rock tip in the image; the maximum value of the rock's vertical length is the vertical distance from the highest point of the rock to the horizontal plane at the bottom of the rock, obtained by the second camera module in the captured rock image; the maximum value of the rock's horizontal length is the longest line segment formed by the intersection of the horizontal line and the rock in the captured rock image.

[0059] Optionally, the visual detection submodule includes an image acquisition unit, a target recognition unit, and a data analysis unit that are connected in sequence and communicate with each other. The data analysis unit is also connected in communication with the control module. The image acquisition unit includes a first camera module that is fixedly connected to the chisel hammer and a second camera module that takes pictures around the rock.

[0060] The image acquisition unit is used to acquire images and transmit them to the target recognition unit; wherein the first camera module is used to acquire images of the chisel hammer and transmit them to the target recognition unit, and the second camera module is used to acquire images of the rock and transmit them to the target recognition unit.

[0061] The target recognition unit converts the acquired image into a target image according to the set target and transmits it to the data analysis unit;

[0062] The data analysis unit is used to analyze and obtain information such as the maximum value of the angle during the y-th rock surface tip detection, the contact area between the hammer and the rock, the maximum value of the rock length in the vertical direction, the maximum value of the rock length in the horizontal direction, the total number of cracks on the rock surface, and the length of the b-th rock crack, and transmits this information to the control module.

[0063] Optionally, when calculating the maximum impact factor of the chisel hammer, the control module satisfies the following formula:

[0064]

[0065]

[0066]

[0067]

[0068] Where YL is the maximum impact factor of the hammer, ky is the rock compressive strength reference index, and bf is the rock treatment index. bf has the following values: bf = 2 or bf = 3. When bf = 2, the rock has been softened before hammering; when bf = 3, the rock has not been softened before hammering. qt Z represents the hardness value of the chisel hammer, and Z represents the total number of rock hardness tests. z Let represent the hardness value of the rock in the z-th test, and Y represent the total number of tests conducted on the rock surface tip. cj represents the maximum angle during the y-th rock surface tip detection. v The impact velocity of the chisel hammer, cj pl cj is the impact frequency of the chisel hammer. jg s is the feed rate of the chisel hammer. ty The contact area between the hammer and the rock is denoted by 'years', the total number of years the hammer has been in use is 'xl', and the total number of times the hammer has been repaired is 'xl'. The feed rate of the hammer is the travel distance of the hammer.

[0069] A is a reference index for rock type. A can take the following values: A = 2, A = 4, or A = 6. When A = 2, the rock type is sedimentary rock; when A = 4, the rock type is igneous rock; and when A = 6, the rock type is metamorphic rock. max Ku represents the maximum vertical length of the rock. max Let lx be the maximum horizontal length of the rock, B be the total number of cracks on the rock surface, and lx be the maximum value of the horizontal length of the rock. b Let be the length of the b-th rock fissure.

[0070] Specifically, when performing rock surface tip detection, the midpoint of the rock in the vertical direction is defined by the maximum value of the rock's vertical length, i.e., the midpoint of the vertical line segment from the top to the bottom of the rock. This midpoint is used as the shooting height and set as a fixed value. Then, the shooting position is changed horizontally, and the total number of times the shooting position is changed is the total number of rock surface tip detections. Generally, 360° divided by the total number of rock surface tip detections is used as the angle of a single shooting position adjustment. The captured images are then filtered. It should be noted that, given that in practice, tips are usually acute angles less than 90°, this embodiment deletes tips with angles greater than 90°. The remaining tip angle range is 0° to 90°. At this point, the rock surface tip detection results are selected. The maximum value of the angle is the maximum value of the angle when the tip of the rock surface is detected each time. The maximum value of the angle when the tip of the rock surface is detected from different directions is the maximum value of the angle. When calculating the contact area between the hammer and the rock, the following should be noted: the contact area refers to the contact area between the hammer and the ground when the hammer is placed vertically on the ground. Then, the maximum diameter of the area projected onto the ground is measured. The contact area between the hammer and the rock is obtained by multiplying the square of half of the maximum diameter by π. This embodiment is based on the premise that the contact area with the rock is the same each time. When calculating the total service life of the hammer, the following should be noted: the total service life of the hammer is the time from the initial use of the hammer to the present. If the total service life of the hammer is less than one year, it is calculated as one year.

[0071] The following is a practical example illustrating how to obtain the rock compressive strength reference index: First, determine the total number of rock hardness tests based on the maximum vertical length of the rock. Let's assume the maximum vertical length of the rock in this test is 0.8 meters and the maximum horizontal length is 0.6 meters, resulting in a total of 3 rock hardness tests. Assuming the rock type is sedimentary rock, the corresponding rock type reference index is 2. Then, measure the hardness value of each rock test, the total number of cracks on the rock surface, and the length of each crack. Substitute all these values ​​into the formula for the rock compressive strength reference index to obtain its specific value.

[0072] Optionally, when the control module calculates the maximum impact pressure selection function for the chisel hammer, it satisfies the following formula:

[0073]

[0074] Where W is the selection function for the maximum impact pressure of the hammer, and w1 to w x The selection threshold for the maximum impact pressure of different chisel hammers, satisfying w1 to w x Getting bigger and bigger, yl1 to yl x-1 The selection threshold for the maximum impact factor of different chisel hammers.

[0075] Specifically, the larger the value of the maximum impact factor of the hammer, the larger the value of the maximum impact pressure of the hammer.

[0076] Optionally, the data analysis unit also obtains information on the chisel diameter formed after the last impact, the structural similarity between the initial chisel hammer and the chisel hammer after the last impact, and the angle formed between the front half of the initial chisel hammer and the front half of the chisel hammer after the last impact (this angle information is obtained by the first camera module), and transmits it to the control module.

[0077] The control module calculates the rotation reference factor of the chisel hammer based on relevant information, calculates the rotation angle selection function of the chisel hammer based on the rotation reference factor, and transmits the rotation angle information of the chisel hammer to the chisel module.

[0078] The adjustment submodule receives information about the rotation angle of the chisel hammer and limits the movement mode of the chisel hammer based on the rotation angle information.

[0079] Optionally, when the control module calculates the rotation reference factor of the chisel hammer, it satisfies the following formula:

[0080]

[0081] Where JD is the rotation reference factor of the hammer, s before j is the diameter of the cut formed after the last impact. xs The structural similarity between the initial hammer and the hammer after the last impact is denoted by μ, which is the angle formed between the front half of the initial hammer and the front half of the hammer after the last impact, i.e., the angle between the vertical planes where the front half of the initial hammer and the front half of the hammer after the last impact are located, which is less than or equal to 90°.

[0082] Specifically, the chisel kerf diameter formed after the last chisel strike refers to the area obtained by measuring the chisel kerf on the rock surface before the current chisel strike. Regarding the calculation of the structural similarity between the initial chisel strike and the chisel strike after the last impact, the structural similarity is composed of brightness, contrast, structure, and a constant. Specifically, referring to existing technology, a structural similarity value of 1 indicates that the two images of the initial chisel strike and the chisel strike after the last impact are identical, meaning the chisel strike has no wear. The smaller the structural similarity, the less similar the two images of the initial chisel strike and the chisel strike after the last impact are. The above-mentioned structural similarity is used to measure the wear degree of the chisel strike. Calculation... When determining the angle between the initial hammer section and the hammer section after the previous impact, the following points should be noted: When photographing the initial hammer, mount the hammer on the main unit, then set the main unit vertically so that the length of the hammer is also set vertically. Then take the image before the initial impact. When photographing the hammer after the previous impact, follow the same requirements. Then compare the two hammers in the two images to obtain the angle between the corresponding initial hammer section and the hammer section after the previous impact. The angle between the initial hammer section and the hammer section after the previous impact should be less than 90°.

[0083] Optionally, when the control module calculates the rotation angle selection function of the chisel hammer, it satisfies the following formula:

[0084]

[0085] Where U is the rotation angle selection function of the hammer, u1 to u p Select threshold values ​​for the rotation angles of different chisels and hammers, satisfying u1 to u p It's getting bigger and bigger, from JD1 to JD p-1 The threshold for selecting the rotation reference factor for different chisels and hammers.

[0086] Specifically, the larger the value of the rotation reference factor of the hammer, the larger the value of the rotation angle of the hammer.

[0087] Although no specific units are provided in the above formulas in this embodiment, those skilled in the art will certainly set appropriate units according to the needs of actual applications.

[0088] This embodiment solves the problem of the short service life of traditional chisels and hammers. Specifically, this embodiment uses a control module to calculate the maximum impact pressure selection function of the chisel and hammer based on relevant rock information and chisel and hammer information. The obtained maximum impact pressure information of the chisel and hammer is fed back to the adjustment submodule in a timely manner. The adjustment submodule adjusts the movement mode of the chisel and hammer to chisel the rock as quickly as possible, while also providing a certain degree of protection for the chisel and hammer and extending its service life.

[0089] In addition, after each impact, the chisel hammer needs to be adjusted to rotate a certain angle before the next impact to change the position of the chisel hammer's edge and achieve a better chiseling effect. Therefore, by obtaining the chisel hammer's rotation angle information through the control module, the rotation angle of the chisel hammer can be strictly controlled to reduce the situation where the chisel hammer's rotation angle is too large and wears down the chisel hammer's surface. At the same time, it can also reduce the situation where the chisel hammer's rotation angle is too small and reduces the chiseling effect.

[0090] Finally, the detection module can achieve automatic identification and measurement functions by applying advanced technologies such as artificial intelligence and computing, thereby improving the overall operating speed, chiseling efficiency, chiseling accuracy, construction safety, and extending tool life.

[0091] Example 2: This example includes all the content of Example 1, and provides an intelligent rock chisel hammer, combined with... Figure 3 As shown.

[0092] An intelligent rock chisel tiger head hammer also includes a data setting module and an alarm module, both of which are communicatively connected to the control module;

[0093] The data setting module is used to set relevant data and obtain information on structural similarity weight index and angle weight index, and then transmit it to the control module;

[0094] The control module calculates the hammer monitoring factor based on the structural similarity weight index, angle weight index, structural similarity between the initial hammer and the hammer after the last impact, and the angle formed between the first half of the initial hammer and the first half of the hammer after the last impact. Based on the hammer monitoring factor, the control module obtains the hammer monitoring information and transmits the hammer monitoring information to the alarm module.

[0095] The alarm module triggers an alarm based on the monitoring information from the chisel hammer.

[0096] When the control module calculates the monitoring factor for the chisel hammer, the following formula is satisfied:

[0097] JC=qz xs *(1-j xs )+qz jd *sinμ;

[0098] Where JC is the monitoring factor for the chisel hammer, and qz xs qz is the structural similarity weight index. jd This is the angle weighting index.

[0099] Specifically, the sum of the structural similarity weight index and the angle weight index is 1.

[0100] When the control module calculates the monitoring information of the chisel hammer, it satisfies the following formula:

[0101]

[0102] Where R represents the monitoring information of the chisel hammer, jc τ The threshold value for selecting the monitoring factor of the chisel hammer is: when R=1, the chisel hammer can work normally and no alarm is needed; when R=2, the chisel hammer cannot work normally and an alarm is needed.

[0103] Although no specific units are provided in the above formulas in this embodiment, those skilled in the art will certainly set appropriate units according to the needs of actual applications.

[0104] This embodiment solves the problem that traditional chisels and hammers cannot be automatically monitored. Specifically, this embodiment monitors the chisels and hammers through a visual detection submodule, automatically outputs relevant information, and then uses a control module to obtain the chisels and hammer monitoring information. When the chisels and hammers cannot work properly, the alarm module can promptly issue an alarm, which provides a certain degree of protection for both the workers and the chisels and hammers.

Therefore, all equivalent technical changes made based on the content of the present invention specification and drawings are included within the scope of protection of the present invention. Furthermore, the elements therein can be updated as technology develops.
