Description

Technical Field

[0001] The invention belongs to the technical field of mobile equipment testing, and in particular relates to a measuring trolley for measuring the height difference of a busbar. Background Art

[0002] Stackers and bridge cranes are important production equipment in production work. Both are mobile working equipment. Most of them use sliding contacts and busbars to supply power. When the equipment moves, the sliding contacts and busbars move closely. Stackers and bridge cranes use rails for lateral movement. The height difference between the rails and the busbars is generally a fixed value. However, due to the weight of the work site and the equipment itself, the rails may deform or the foundation may loosen, causing the rails to be uneven. The height of the busbar does not change with the height of the rail because it is installed on a bracket. Over time, the height difference between the busbar and the rail varies, often causing problems such as the busbar being squeezed and damaged, the sliding contact being squeezed and damaged, the sliding contact falling off, and the busbar deforming and causing a three-phase short circuit.

[0003] Since stackers and bridge cranes have a large range of activities, and the length of tracks and busbars is often hundreds of meters, personnel are unable to quickly and accurately measure the height differences between tracks and busbars, making it difficult to quickly detect and handle abnormal height differences, and unable to detect continuous deterioration of equipment.

[0034] In order to describe the present invention in detail, a measuring vehicle for measuring the height difference of a busbar according to the present invention is specifically described below:

[0035] Please combine Figure 1 As shown, the present invention provides a measuring trolley for measuring the height difference of a busbar, which is used to measure the distance between the busbar 200 and the track 100, and includes: a car body 1, a driving assembly 2, a lifting frame 3, a mounting bracket 4 and a distance measuring sensor 5, wherein the car body 1 is slidably arranged on the track 100; the driving assembly 2 is arranged on the car body 1, and is used to drive the car body 1 to reciprocate on the track 100; the lifting frame 3 is arranged in the car body 1, and a mounting bracket 4 extending out of the car body 1 and rotatable is arranged on the top of the lifting frame 3, and the lifting frame 3 is used to lift the mounting bracket 4 in a vertical direction; the distance measuring sensor 5 is arranged on the mounting bracket 4; by adjusting the height position of the lifting frame 3 and the rotation position of the mounting bracket 4, the distance measuring sensor 5 can be aligned with the busbar 200 in the vertical direction to measure the height difference of the busbar 200.

[0036] Specifically, the stacker and the bridge crane travel on the track 100 by using the power fed from the busbar 200 as the power source, the extension direction of the track 100 is the first direction, and the direction perpendicular to the horizontal plane is defined as the second direction. The car body 1 can reciprocate along the extension direction of the track 100. The drive assembly 2 is used to drive the car body 1 to move forward or backward, and can achieve accurate measurement of different positions of the busbar 200. The guide rail of the busbar 200 is suspended under the installation beam through a hanger, and the guide rail of the busbar 200 is installed to basically maintain a constant height (reference height) from the track 100. There is an accommodating space inside the car body 1, and the lifting frame 3 is arranged in the accommodating space. The lifting frame 3 can perform lifting and lowering movements to lift or lower the mounting bracket 4 and the distance sensor 5 thereon, that is, by adjusting the height position of the lifting frame 3, the height of the distance sensor 5 relative to the busbar 200 can be adjusted to meet the measurement requirements of the busbar 200 at different heights. In addition, the mounting bracket 4 can rotate relative to the lifting frame 3 about a first direction (i.e., about the extension direction of the track, in a vertical plane), so as to adjust the angle of the distance sensor 5 mounted on the mounting bracket 4 relative to the busbar 200. The distance sensor 5 is mounted on the mounting bracket 4 with adjustable height and rotation angle, ensuring the precise alignment of the busbar 200 in the vertical direction, thereby improving the accuracy of the measurement. By adjusting the height position of the lifting frame 3 and the rotation position of the mounting bracket 4, the distance sensor 5 can be aligned with the busbar 200 in the vertical direction, and the height of the busbar 200 from the track is calculated based on the distance measured by the distance sensor 5, so that the height difference between the busbar 200 of the stacker and the bridge crane and the track can be measured quickly and conveniently, which is convenient for equipment inspection and maintenance; the operation is convenient and the measurement is accurate. Because it can continuously measure over a long distance, the deterioration trend of the equipment can be effectively discovered.

[0037] In some embodiments, the distance sensor 5 is slidably disposed on the mounting bracket 4, and the mounting bracket 4 is parallel to the horizontal plane. Specifically, the distance sensor 5 can be an infrared distance sensor 5. The distance sensor 5 is slidably disposed on the mounting bracket 4, allowing the user to make fine adjustments according to the specific position of the busbar 200, so as to adjust the horizontal position of the distance sensor 5 on the mounting bracket 4, ensuring that the distance sensor 5 can be accurately aligned with the busbar 200, thereby further improving the accuracy of the measurement. The design of the mounting bracket 4 being parallel to the horizontal plane helps to maintain the stability of the distance sensor 5.

[0038] In the above embodiment, the mounting bracket 4 includes a first sub-frame part 41 and a second sub-frame part 42 which are rotatably connected, and the first sub-frame part 41 is rotatably connected to the lifting frame 3, and the distance sensor 5 is slidably arranged on the second sub-frame part 42. Among them, through the rotational connection between the first sub-frame part 41 and the lifting frame 3, and the rotational connection between the second sub-frame part 42 and the first sub-frame part 41, the mounting bracket 4 provides a plurality of degrees of freedom of adjustment space, thereby allowing the distance sensor 5 to be adjusted in all directions in three-dimensional space to meet the measurement requirements of the busbar 200 at different positions, angles and heights. The mounting bracket 4 is rotatably arranged on the top of the lifting frame 3, which is conducive to adjusting the position of the distance sensor 5 located on the mounting bracket 4 relative to the busbar 200 by adjusting the rotation angle of the mounting bracket 4. The first sub-frame part 41 can be rotated 180 degrees relative to the lifting frame 3 (in a vertical plane), and the second sub-frame part 42 can be rotated in a vertical plane relative to the first sub-frame part 41. By finely adjusting the rotation angles of the first frame portion 41 and the second frame portion 42 , and the sliding position of the distance measuring sensor 5 on the second frame portion 42 , the distance measuring sensor 5 can be aligned with the busbar 200 .

[0039] It can be understood that the rotation connection between the first sub-frame part 41 and the lifting frame 3, and the rotation connection between the first sub-frame part and the second sub-frame part 42 are both provided with a rotating dial 43 for controlling the rotation angle. By providing the rotating dial 43, it is convenient to accurately control the rotation angle of the first sub-frame part 41 and the second sub-frame part 42, thereby facilitating the position adjustment of the distance sensor 5 and improving the measurement accuracy. By performing precise adjustment by rotating the dial 43, the operator can find the best measurement position more quickly, thereby improving the measurement efficiency.

[0040] In some embodiments, the driving assembly 2 includes a driving motor 21, a driving gear 22, a transmission gear set 23 and a moving wheel 24 arranged at the bottom of the vehicle body 1, the driving gear 22 is connected to the output end of the driving motor 21, and the moving wheel 24 is connected to the driving gear 22 through the transmission gear set 23. Specifically, a fixed frame is provided at the bottom of the vehicle body 1, and the driving motor 21 is installed on the fixed frame as a power source for driving the vehicle body 1 to move back and forth. The driving motor 21 transmits power to the moving wheel 24 through the driving gear 22 and the transmission gear set 23 in turn. The gear transmission has good stability and is not prone to sliding and impact, which helps to ensure the smooth travel of the vehicle body 1.

[0041] In the above embodiment, the transmission gear set 23 includes a main transmission gear 231 and two auxiliary transmission gears 232 connected coaxially, the main transmission gear 231 is located between the two auxiliary transmission gears 232, the main transmission gear 231 is meshed with the driving gear 22, and the two auxiliary transmission gears 232 are respectively meshed with the corresponding moving wheels 24. Specifically, the main transmission gear 231 and the two auxiliary transmission gears 232 rotate synchronously, and the driving gear 22 transmits power to the two auxiliary transmission gears 232 through the main transmission gear 231 at the same time, and then transmits power to the corresponding moving wheels 24 through the two auxiliary transmission gears 232, thereby driving the vehicle body 1 to move on the track 100.

[0042] It can be understood that the axial directions of the output end of the driving motor 21, the driving gear 22, the transmission gear set 23 and the moving wheel 24 are parallel to each other. The transmission gear set 23 is located below the driving gear 22, and the moving wheel 24 is located below the transmission gear set 23. The axially parallel design enables the various parts of the driving assembly 2 to be closely arranged together, thereby optimizing the overall layout and improving space utilization.

[0043] In the above embodiment, the driving assembly 2 further includes a power battery 25, which is disposed at the bottom of the vehicle body 1 and is disposed on the opposite side of the driving motor 21, and the power battery 25 is electrically connected to the driving motor 21. In this example, the power battery 25 is also disposed on a fixed frame at the bottom of the vehicle body 1 and is disposed on the opposite side of the driving motor 21, thereby facilitating a balanced distribution of the weight of the vehicle body 1 and improving the driving stability of the vehicle. The power battery 25 is connected to the driving motor 21 through an electrical connection, ensuring rapid and efficient transmission of electrical energy.

[0044] It should be noted that the driving assembly 2 also includes a side shaft 26 connected to the bottom of the vehicle body 1 in a vertical direction and a side wheel 27 connected to the side shaft 26. The two side wheels 27 are symmetrically arranged on both sides of the track 100 and abut against the side walls of the track 100. Specifically, in this example, the driving gear 22, the transmission gear set 23 and the moving wheel 24 are all located between the two side shafts 26. The axial direction of the side wheel 27 is perpendicular to the axial direction of the moving wheel 24. The side wheel 27 can be raised and lowered along its own axial direction, and the side wheel 27 can be dropped during testing. The abutment of the outer peripheral wall of the side wheel 27 against the side wall of the track 100 provides an additional support point for the vehicle body 1, thereby enhancing the stability of the vehicle body 1 during driving.

[0045] In the above embodiment, the vehicle body 1 is provided with a push rod 11, and the push rod 11 is provided with a display screen 12 for displaying data, and a control button 13 for controlling the vehicle body 1 to move forward or backward. Specifically, the height of the busbar 200 is calculated based on the output value of the distance sensor 5 and the height value of the track 100 by using set parameters and a pre-prepared program. The push rod 11 can facilitate the operator to push the trolley, the control button 13 can control the vehicle body 1 to move forward or backward, and the display screen 12 is pre-stored with a measurement program for recording the data of the distance sensor 5. The data measured by the distance sensor 5 is recorded through the pre-stored program and a continuous measurement trend chart is generated.

[0046] When the measuring vehicle for measuring the height difference of the busbar 200 is used specifically, when it is necessary to measure the height difference between the busbar 200 of the stacker and the track 100, the vehicle body 1 needs to be placed above the track 100 first, and the side wheels 27 of the vehicle body 1 need to be lowered to ensure that the vehicle body 1 is relatively stable during travel, the lifting frame 3 and the mounting bracket 4 need to be adjusted, the distance sensor 5 needs to be aligned with the busbar 200 in the vertical direction, the measurement program installed in the display screen 12 needs to be started, and the control button 13 needs to be pressed to control the forward or backward movement, and the height difference of a certain section of the area to be measured is measured. After the measurement is completed, the height difference value of a certain point and the height difference change trend diagram of a certain section can be viewed on the display screen 12. When measuring the height difference between the busbar 200 of the bridge crane and the track, because the installation position of the busbar 200 of the bridge crane is different from that of the stacker and reclaimer, the height and rotation direction of the lifting frame 3 and the mounting bracket 4 can be adjusted, and the measurement method is the same as the above method.

[0047] In summary, the present invention provides a measuring trolley for measuring the height difference of a busbar 200. By arranging a rotatable mounting bracket 4 on a lifting frame 3 in a vehicle body 1, and arranging a distance measuring sensor 5 on the mounting bracket 4, the distance measuring sensor 5 can be aligned with the busbar 200 in the vertical direction by adjusting the height position of the lifting frame 3 and the rotation position of the mounting bracket 4. The height of the busbar 200 from the track is calculated based on the distance measured by the distance measuring sensor 5. The height difference between the busbar 200 and the track of a stacker and bridge crane can be measured quickly and conveniently, which is convenient for equipment inspection and maintenance. The operation is convenient and the measurement is accurate. Since long-distance continuous measurement is possible, the deterioration trend of the equipment can be effectively discovered.

[0048] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
