Description

Technical Field

[0001] This utility model relates to the field of crane boom detection, specifically to a tool for measuring the degree of crane boom deformation. Background Technology

[0002] Crane boom deformation detection typically involves measuring geometric changes such as bending and twisting of the boom to ensure its safety and stability when carrying heavy loads. The purpose of deformation detection is to promptly identify potential structural problems and prevent excessive deformation from causing equipment failures, accidents, or other safety hazards.

[0003] For example, patent application number 202223091150.7 discloses a crane boom deformation detection device, which attaches a detection plate to the lower surface of the boom and uses a laser rangefinder. When the boom is deformed, the detection plate is subjected to uneven pressure, and the distance of the laser beam hitting the reflective paper changes, resulting in more accurate test data.

[0004] However, the above-mentioned crane boom deformation detection device still has the following shortcomings: its track pulley rotates along the boom, and the detection plate is in close contact with the lower surface of the boom. Although this detection method can detect where the boom is deformed, it is only suitable for installation on booms with a certain width. If the boom is too wide or too narrow, it cannot detect the deformation of the boom.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0006] In view of the problems in the related technologies, this utility model proposes a tool for measuring the deformation degree of a crane boom, so as to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] Therefore, the specific technical solution adopted by this utility model is as follows:

[0008] A tool for measuring the deformation of a crane boom includes connecting seats at both ends of the top of the crane boom, a support plate between the two connecting seats, and a support moving mechanism on the top of the support plate. The support moving mechanism has several detection mechanisms on its top for detecting the deformation of the crane boom, and is used to automatically move the detection mechanisms. A window is provided in the middle of the support plate, and a protective mechanism is provided at one end of the connecting seat near the support plate. The connecting seats are connected to the top of the crane boom via an adhesive plate. The two side edges of the support plate are connected to the ends of the connecting seats via several connecting bolts, and the middle positions of both ends of the support plate are connected to the ends of the connecting seats via positioning shafts.

[0009] Furthermore, in order to support and move the inspection mechanism and drive it to automatically inspect the crane's boom, the support and movement mechanism includes a U-shaped frame set on top of the support plate. Mounting plates are located at the bottom of both ends of the U-shaped frame, with rollers at the bottom of the mounting plates. A motor is located at the top of the mounting plates, with the bottom end of the motor's output shaft connected to the center of the rollers. The rollers contact the sidewalls of the support plate. A support column is located at the top inner part of the U-shaped frame, and a sliding pad is provided between the support column and the top of the support plate. A square hole is located at the top of the U-shaped frame, with the size of the square hole along the short side of the crane boom being larger than the size of the window hole along the short side of the crane boom.

[0010] Furthermore, in order to obtain distance data from each position of the crane boom, the detection mechanism includes a fixed plate set at the top of the U-shaped frame, with a distance sensor installed in the middle of the fixed plate and inside the square hole; both ends of the fixed plate are provided with inserts, and several holes are provided on both sides of the square hole, with an interference fit between the inserts and the holes.

[0011] Furthermore, in order to prevent the supporting moving mechanism from exceeding its working range, the protection mechanism includes a transverse rod provided at one end of the connecting seat near the support plate, and a buffer block provided at the end of the transverse rod near the support plate; a pin hole is provided in the transverse rod, a fixing bolt is screwed to the top of the connecting seat, a pin is provided at the bottom of the fixing bolt, and the bottom end of the pin extends into the pin hole.

[0012] The beneficial effects of this utility model are as follows:

[0013] (1) This utility model can detect the degree of deformation of the crane boom, and thus identify the boom that is too deformed. At the same time, through the combined use of the support plate, the support moving mechanism and the detection mechanism, deformation detection can be carried out on the boom of any width, and it has a wide range of applications.

[0014] (2) By setting up a support plate and a support moving mechanism, the detection mechanism can be supported and moved, thereby automatically detecting the crane boom. The support moving mechanism does not need to directly contact the boom, but moves using the support plate, making it applicable to booms of different widths. By setting up the detection mechanism, distance data from each position of the boom can be obtained through a distance sensor, thus identifying locations where excessive deformation of the boom occurs.

[0015] (3) By setting up a protective mechanism, the support moving mechanism will stop moving forward when it reaches the end of the boom, thus preventing the support moving mechanism from continuing to exceed its working range and causing accidental damage. Attached Figure Description

These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0025] According to an embodiment of the present invention, a tool for measuring the deformation degree of a crane boom is provided.

[0026] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-5 As shown, the crane boom deformation measuring tool according to an embodiment of the present invention includes connecting seats 2 located at both ends of the top of the crane boom, a support plate 3 disposed between the two connecting seats 2, and a support moving mechanism 4 disposed on the top of the support plate 3; the top of the support moving mechanism 4 is provided with a plurality of detection mechanisms 5 for detecting the deformation of the crane boom, and the support moving mechanism 4 is used to automatically move the detection mechanisms 5; a window hole 6 is provided in the middle of the support plate 3, and a protective mechanism 7 is provided at one end of the connecting seat 2 near the support plate 3; the connecting seat 2 is connected to the top of the crane boom by an adhesive plate 1, wherein the adhesive plate 1 and the crane boom use a reversible adhesive (e.g., hot melt adhesive), which can be loosened by heating or other means when needed, making disassembly convenient; the two ends of the support plate 3 are connected to the ends of the connecting seats 2 by a plurality of connecting bolts 8, and the middle positions of the two ends of the support plate 3 are connected to the ends of the connecting seats 2 by positioning shafts 9.

[0027] With the help of the above solution, this utility model can detect the degree of deformation of the crane boom, and thus identify the boom with excessive deformation. At the same time, through the cooperation of the support plate 3, the support moving mechanism 4 and the detection mechanism 5, deformation detection can be carried out on the boom of any width, and the application range is wide.

[0028] In one embodiment, the support moving mechanism 4 includes a U-shaped frame 401 disposed on the top of the support plate 3. Mounting plates 402 are disposed at the bottom of both ends of the U-shaped frame 401. Rollers 403 are disposed at the bottom of the mounting plates 402. The rollers 403 are rotatable and are connected to the bottom of the mounting plates 402 according to their dimensions and via bearings. A motor 404 is disposed at the top of the mounting plates 402. The bottom end of the output shaft of the motor 404 is connected to the center of the rollers 403. The rollers 403 contact the sidewall of the support plate 3. A support column 405 is provided on the inner top of the U-shaped frame 401, and a sliding pad 406 is provided between the support column 405 and the top of the support plate 3. A square hole 407 is provided on the top of the U-shaped frame 401. The size of the square hole 407 along the short side of the crane arm is larger than the size of the window hole 6 along the short side of the crane arm, so as to support and move the detection mechanism 5, drive the detection mechanism 5 to automatically detect the crane arm, and the support and moving mechanism 4 does not need to directly contact the crane arm, but moves with the help of the support plate 3, so it can be used for crane arms of different widths.

[0029] The working principle of the supporting moving mechanism 4 is as follows: the motor 404 is started by an external controller, that is, the motor 404 is driven by outputting control signals (such as digital signals or pulse width modulation signals) to the motor drive module, so that the motor 404 runs at a predetermined speed and direction. At the same time, the control signal can start or stop the motor 404, adjust the speed of the motor 404, and reverse the rotation direction of the motor 404, thereby driving the supporting moving mechanism 4 to move smoothly.

[0030] Specifically, the output shaft of the motor 404 is connected to the center of the roller 403. The rotation of the motor 404 drives the roller 403 to rotate. The roller 403 contacts the side wall of the support plate 3, and the rolling motion causes the U-shaped frame 401 to slide along the support plate 3. The support column 405 ensures the stability of the U-shaped frame 401, and the sliding pad 406 reduces friction, allowing the support moving mechanism 4 to move smoothly along the support plate 3. The square hole 407 at the top of the U-shaped frame 401 and the window hole 6 in the middle of the support plate 3 ensure that there are no obstructions between the detection mechanism 5 and the lifting arm.

[0031] In one embodiment, the detection mechanism 5 includes a fixed plate 501 at the top of the U-shaped frame 401. A distance sensor 502 is provided in the middle of the fixed plate 501 and inside the square hole 407. Both ends of the fixed plate 501 are provided with inserts 503, and both sides of the square hole 407 are provided with several holes 504. The inserts 503 and the holes 504 are interference-fitted, so that the distance data fed back from each position of the crane boom can be obtained through the distance sensor 502, and the position where the crane boom is deformed too much can be determined.

[0032] The working principle of the detection mechanism 5 is as follows: The detection mechanism 5 is installed on the top of the U-shaped frame 401. The fixing plate 501 is connected to the insertion hole 504 through the insertion post 503 to ensure the stability of the fixing plate 501. The distance sensor 502 is located in the middle of the fixing plate 501. As the supporting moving mechanism 4 moves, the distance sensor 502 starts to work, acquiring distance data at different positions of the crane boom one by one. Multiple distance sensors 502 can be installed on the U-shaped frame 401 at one time, thereby improving the detection range of the crane boom.

[0033] The ranging sensor 502 uses principles such as ultrasonic ranging and laser ranging. For example, ultrasonic ranging works by emitting an ultrasonic pulse, which is reflected back after hitting the crane arm. The ranging sensor 502 receives the reflected wave and calculates the distance between the ranging sensor 502 and a certain position on the crane arm based on the propagation time of the ultrasonic wave. Similarly, laser ranging works by emitting a laser pulse, which is reflected back to the ranging sensor 502 after hitting the crane arm. The distance between the ranging sensor 502 and a certain position on the crane arm is calculated by measuring the round-trip time of the laser.

[0034] The ranging sensor 502 internally transmits the collected distance data to an external controller or data acquisition system via a wireless module using wireless technology (such as Wi-Fi, Bluetooth, or Zigbee).

[0035] After the distance sensor 502 collects the distance data and feeds it back to the control system, the system uses this data to determine whether the crane boom has undergone excessive deformation. If the deformation at a certain location exceeds a preset safety threshold, the system will mark the location and issue an alarm, indicating that maintenance or adjustment is required. After the detection is completed, the system will actively send a command through an external controller to set the distance sensor 502 to standby mode.

[0036] In one embodiment, the protection mechanism 7 includes a transverse rod 701 disposed at one end of the connecting seat 2 near the support plate 3, and a buffer block 702 disposed at one end of the transverse rod 701 near the support plate 3; a pin hole 703 is disposed in the transverse rod 701, a fixing bolt 704 is screwed to the top of the connecting seat 2, and a pin shaft 705 is disposed at the bottom end of the fixing bolt 704, and the bottom end of the pin shaft 705 extends into the pin hole 703, so that when the support moving mechanism 4 reaches the end of the lifting arm, the support moving mechanism 4 stops moving forward, preventing the support moving mechanism 4 from continuing to exceed its working range and causing accidental damage.

[0037] The working principle of the protection mechanism 7 is as follows: by inserting the transverse rod 701 into the connecting seat 2 and aligning the pin hole 703 on the transverse rod 701 with the pin 705 connected to the bottom of the fixing bolt 704, the fixing bolt 704 is rotated so that the pin 705 is lowered and finally inserted into the pin hole 703, thus keeping the transverse rod 701 and the buffer block 702 in a fixed state.

[0038] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0039] 1. Initialization and Installation

[0040] The various components of the boom deformation detection device (such as support plate 3, support moving mechanism 4, detection mechanism 5, etc.) are installed on the boom of the crane. The support plate 3 is fixed to the boom by the cooperation of components such as connecting seat 2, adhesive plate 1, and connecting bolts 8.

[0041] 2. Support the start of the moving mechanism 4

[0042] The motor 404 is started, and the output shaft of the motor 404 drives the roller 403, which is in contact with the side wall of the support plate 3, to rotate. The rotation of the roller 403 causes the U-shaped frame 401 and its connected components to slide along the surface of the support plate 3. The support column 405 provides support for the U-shaped frame 401, and the sliding pad 406 reduces friction, so that the support moving mechanism 4 can move smoothly along the support plate 3.

[0043] 3. Movement and deformation detection of testing mechanism 5

[0044] The square hole 407 at the top of the U-shaped frame 401 is large enough to accommodate the detection mechanism 5. As the supporting moving mechanism 4 moves, the distance sensor 502 in the detection mechanism 5 fixed at the top of the U-shaped frame 401 starts to work, detecting the distance changes of the crane boom at different positions in real time. The distance sensor 502 feeds the distance data at different positions back to the control system to detect whether the crane boom has undergone excessive deformation.

[0045] 4. Data Analysis and Judgment

[0046] The control system analyzes the received distance data to determine if the crane boom has deformed beyond a preset threshold. If deformation at a certain point on the crane boom exceeds the set range, the system will mark the location of the excessive deformation and issue an alarm.

[0047] 5. The function of protection mechanism 7

[0048] When the support moving mechanism 4 reaches the end of the lifting arm, the buffer block 702 of the protection mechanism 7 will come into contact with the support moving mechanism 4 to prevent the support moving mechanism 4 from moving further and to prevent damage caused by excessive movement.

[0049] In summary, this invention can detect the deformation degree of a crane boom, thereby identifying booms with excessive deformation. Furthermore, through the coordinated use of the support plate 3, the support moving mechanism 4, and the detection mechanism 5, deformation detection can be performed on booms of any width, making it widely applicable. By setting up the support plate 3 and the support moving mechanism 4, the detection mechanism 5 can be supported and moved, automatically detecting the crane boom. The support moving mechanism 4 does not need to directly contact the boom but moves using the support plate 3, thus making it applicable to booms of different widths. By setting up the detection mechanism 5, distance data from each position of the boom can be obtained through the distance sensor 502, thereby identifying locations where excessive deformation of the boom occurs. By setting up the protection mechanism 7, when the support moving mechanism 4 reaches the end of the boom, it stops moving forward, preventing the support moving mechanism 4 from exceeding its working range and causing accidental damage.

Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
