Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, and in particular to a mounting bracket kit for detecting displacement data of lifting equipment with an encoder. Background Technology

[0002] Cranes are core equipment in material handling and engineering operations. Displacement data detection of key moving parts such as reels and wheels is an important prerequisite for achieving precise equipment control and ensuring safe operation.

[0003] In existing technologies, the detection of displacement data of lifting equipment mainly adopts pressure roller scheme or mechanical driven roller scheme. Both schemes complete data acquisition by direct contact between the measuring wheel and the wheel being detected. However, such contact detection structures are prone to relative slippage on the contact surface, resulting in large errors in the encoder output data. Moreover, the strong vibration during the operation of the lifting equipment can easily cause the measuring wheel to fall off and be lost. In addition, this type of structure has strict requirements for the selection of the installation position, and the conventionally selected installation position can also cause inconvenience to the daily maintenance of the equipment.

[0013] The wheel guard can be detachably mounted on the connecting bracket.

[0014] Furthermore, both ends of the crossbeam are provided with mounting adjustment holes for the connector to pass through and fix the crossbeam at the installation position. The mounting adjustment holes are U-shaped elongated holes extending along the length of the crossbeam.

[0046] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0047] Example:

[0048] like Figure 1-5 The image shown is a mounting bracket kit for detecting displacement data of lifting equipment with an encoder, provided in this embodiment. It includes a crossbeam 1, a connecting frame assembly 2, a guard wheel frame 3, and a tensioning structure 4.

[0049] The crossbeam 1 is installed at the installation position of the lifting equipment. One end of the connecting frame assembly 2 is hinged to the crossbeam 1, and a locking structure is provided at the hinge. The locking structure is used to fix the connecting frame assembly 2 to the crossbeam 1 after the angle is adjusted. An encoder 8 is installed at the other end of the connecting frame assembly 2. The guard wheel frame 3 is provided on the connecting frame assembly 2, and a guard wheel area is formed between the guard wheel frame 3 and the input shaft of the encoder 8. The measuring wheel 9 is installed in the guard wheel area. The measuring wheel 9 is coaxially connected to the input shaft of the encoder 8, and the axis of the measuring wheel 9 is parallel to the axis of the rotating body to be measured of the lifting equipment.

[0050] The connecting frame assembly 2 is connected to the crossbeam 1 by the tensioning structure 4, and the tensioning structure 4 is used to provide tension for the meter wheel 9 to roll and abut against the rotating body to be measured of the lifting equipment.

[0051] In a specific embodiment, the connecting frame assembly 2 includes a connecting bracket 21 and a connecting seat 22; as shown Figure 6-7 As shown, the crossbeam 1 is provided with a connecting frame mounting hole 11 along its length direction. In this embodiment, the crossbeam 1 is a rectangular frame, and the length direction is the direction of its long side. The fastener 24 can pass through the assembly hole on the connecting seat 22 and the connecting frame mounting hole 11 to fix the connecting seat 22 to the crossbeam 1.

[0052] The locking structure includes a connecting shaft 25 and a locking element 26;

[0053] The measuring wheel and the encoder are respectively located on both sides of the same end of the connecting bracket 21. The end of the connecting bracket 21 away from the measuring wheel is rotatably connected to the connecting seat 22 through the connecting shaft 25, and the connecting bracket 21, the connecting shaft and the connecting seat 22 can be locked and fixed by the locking member 26.

[0054] The wheel guard 3 is detachably mounted on the connecting bracket 21. In this embodiment, the connecting shaft is a connecting bolt, and the locking element is a locking nut. The two work together to fix the connecting bracket and the connecting seat and adjust the angle between the connecting bracket and the connecting seat, improving the installation flexibility of the bracket set. The mounting hole 11 of the connecting bracket is set along the length of the crossbeam 1. With the detachable fixing of the connecting seat 22, the installation position of the connecting bracket assembly 2 on the crossbeam 1 can be flexibly adjusted to meet the detection requirements of the rotating body to be tested at different positions on different cranes. The connecting bracket 21 is rotatably connected to the connecting seat 22 through the connecting shaft. The locking nut locks the angle and allows for flexible adjustment of the installation angle. The meter counting wheel 9 and the encoder 8 are respectively located on both sides of the same end of the connecting bracket 21. The layout is compact and avoids mutual interference, ensuring stable detection signals. The wheel guard 3 is detachably mounted on the connecting bracket 21, which facilitates the disassembly and maintenance of the meter counting wheel and improves ease of use. In this embodiment, the connecting bracket 21 and the connecting seat 22 are designed as an integral welded unit.

[0055] In a specific embodiment, both ends of the crossbeam 1 are provided with mounting adjustment holes 12 for the connector 5 to pass through and fix the crossbeam 1 at the installation position. The mounting adjustment hole 12 is a U-shaped elongated hole extending along the length direction of the crossbeam 1, with the opening of the U-shaped elongated hole facing outward in the length direction, which facilitates the assembly and disassembly of the connector 5. With mounting adjustment holes 12 extending along the length direction at both ends of the crossbeam 1, when the connector 5 passes through the elongated hole to fix the crossbeam 1, the length direction position of the crossbeam 1 can be flexibly adjusted at the installation position, adapting to the installation space of different lifting equipment and the position of the rotating body to be measured, thus enhancing the versatility of the support set.

[0056] In a specific embodiment, a mounting block 6 is also included. The mounting block 6 can be fixed to the installation position by welding or bolting. The connecting piece 5 can pass through the mounting adjustment hole 12 and the connecting hole 61 on the mounting block 6 to fix the crossbeam 1 to the mounting block 6. That is, the crossbeam 1 and the mounting block 6 are detachably connected. When the device needs to be disassembled for replacement or maintenance, the connecting piece 5 can be easily disassembled to release the fixed relationship between the crossbeam 1 and the mounting block 6. During disassembly and assembly, it is not necessary to remove the mounting block 6 from the installation position of the lifting equipment, thus avoiding damage to the equipment. The structure of the installation location causes secondary damage; the crossbeam 1, together with the connecting frame assembly 2, encoder 8, meter wheel 9 and other components, can be directly removed for inspection and maintenance, greatly simplifying the disassembly and assembly process; after inspection or replacement, it is only necessary to re-pass the connecting piece 5 through the installation adjustment hole 12 of the crossbeam 1 and the connection hole of the mounting block 6 to complete the reset and fixation of the crossbeam 1. Moreover, with the help of the elongated hole structure of the installation adjustment hole 12 along the length of the crossbeam 1, the installation position of the crossbeam 1 can still be flexibly adjusted after reset to adapt to the detection requirements of the rotating body to be tested, taking into account both maintenance convenience and installation adaptability.

[0057] In a specific embodiment, the crossbeam 1 is provided with a tensioning structure connecting frame 7. The crossbeam 1 and the tensioning structure connecting frame are connected by welding or bolts. The tensioning structure connecting frame 7 is provided with a first tensioning structure connecting hole 71. The hook at one end of the tensioning structure 4 is engaged with the first tensioning structure connecting hole 71, and the hook at the other end of the tensioning structure 4 is engaged with the second tensioning structure connecting hole 211 on the connecting bracket 21. The tension of the tensioning structure 4 keeps the connecting bracket 21 and the crossbeam 1 tensile. The engagement of the first tensioning structure connecting hole 71 and the second tensioning structure connecting hole 211 on the connecting bracket 21 achieves a reliable connection of the tensioning structure 4. The tension of the tensioning structure 4 keeps the connecting bracket 21 and the crossbeam 1 tensile, providing a continuous and stable preload for the rolling contact between the measuring wheel and the rotating body to be measured, ensuring the reliability of their contact, and enhancing the installation stability of the connecting bracket 21, reducing angular deviation caused by equipment vibration, and improving displacement detection accuracy. In this embodiment, the connecting bracket 21 is provided with a plurality of second tensioning structure connecting holes 211 in sequence along the direction from near the crossbeam to away from the crossbeam. In actual use, the tension spring can be connected to the second tensioning structure connecting hole 211 at a suitable position.

[0058] In a specific embodiment, the wheel guard 3 includes a first plate 31, a second plate 32 and a third plate 33. The first plate 31 is installed on one side of the connecting bracket 21 (the two are bolted together). The third plate 33 is disposed opposite to the first plate 31, and the third plate 33 and the first plate 31 are connected on the same side through the second plate 32. The second plate 32, the third plate 33 and the first plate 31 are welded or integrally formed.

[0059] The encoder is installed on the side of the connecting bracket 21 away from the wheel guard 3, and the input shaft of the encoder extends into the wheel guard 3 through the second mounting hole 212 on the connecting bracket 21. The counting wheel is fixedly mounted on the input shaft of the encoder and is rotatably disposed in the wheel guard area. The wheel guard 3, composed of the first plate 31, the second plate 32, and the third plate 33, can provide multi-directional protection for the counting wheel and, in conjunction with the encoder input shaft, form a semi-enclosed limiting space, reducing the risk of wheel detachment, wheel loss, and collision between the counting wheel and other components after wheel detachment. The layout of the counting wheel fixed on the encoder input shaft and located on both sides of the connecting bracket 21 ensures the coaxial transmission accuracy of the encoder and the counting wheel, reduces detection errors, and allows for a compact component layout, avoiding mutual interference and improving the overall structural stability.

[0060] In a specific embodiment, the tensioning structure 4 is a tension spring; the tension spring provides a constant preload for the rolling contact between the measuring wheel and the rotating body under test of the lifting equipment, ensuring the reliability of the contact between the measuring wheel and the rotating body under test of the lifting equipment (wheel or drum), thereby ensuring the accuracy and stability of the lifting displacement detection data. Figure 8-10 The diagrams shown illustrate how the encoder mounting bracket kit for detecting displacement data of lifting equipment, after being assembled with the meter wheel and sensor, is installed (overlapped) on the wheel and positioned at different locations on the crane; as shown... Figure 11 The diagram shows the mounting bracket set for detecting displacement data of lifting equipment using the encoder in this configuration, installed (overlapping) on ​​the drum or shaft and set at different installation positions on the crane. The process and logic of the encoder and meter wheel detecting the displacement of the rotating body under test are existing technologies and not the invention of this solution; therefore, their specific principles will not be elaborated here.

[0061] The present invention discloses the following installation method for a mounting bracket kit for detecting displacement data of lifting equipment with an encoder:

[0062] First, the mounting block is fixed to the appropriate installation position of the lifting equipment with bolts. Then, the crossbeam is installed on the mounting block. Next, the connecting seat 22 of the connecting frame assembly is installed on the mounting hole 11 of the connecting frame with fasteners (bolts) to complete the connection between the connecting frame assembly and the crossbeam. Then, the counting wheel is placed in the guard wheel frame 3. The input shaft of the encoder is inserted into the guard wheel frame 3 through the second mounting hole 212 of the connecting bracket 21 to fix the encoder to the connecting bracket and the input shaft of the encoder to the counting wheel. The angle between the connecting frame assembly and the crossbeam is adjusted so that the counting wheel contacts the rotating body to be measured. Finally, the two ends of the tension spring are fixed to the second tension structure connecting hole 211 of the connecting bracket and the first tension structure connecting hole 71 on the tension structure connecting bracket 7 to ensure that there is sufficient friction between the counting wheel and the rotating body to be measured.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
