Description

Technical Field

[0001] This utility model relates to the field of cross limiters, specifically a multifunctional cross limiter. Background Technology

[0002] Cross limiters are key safety devices in lifting machinery. They precisely limit the range of mechanical movement through sensors and control systems, effectively preventing collisions and boundary crossing accidents, and ensuring the safety of personnel and equipment. They are easy to install, widely used, and play an important role in various mechanical equipment such as cranes and conveyors.

[0003] Some existing cross limit switches are also equipped with laser limit devices, which improves the accuracy and reliability of limit protection. The laser limit switch achieves the limit function by emitting a laser beam and detecting its reflection or obstruction. When the mechanical equipment approaches the predetermined position, the laser beam is blocked or reflected back to the receiver, thereby triggering the limit signal. This principle enables the laser limit switch to provide high-precision, non-contact limit protection, which is suitable for various occasions that require precise control of the movement range. However, there is a problem in the actual installation process. Specifically, the installation and cooperation of traditional laser limit switches with cross limit switches is relatively fixed, usually involving simple angle adjustment. This results in poor adjustability of the laser limit switch and poor adaptability to different installation and usage environments, reducing the ease of installation of the cross limit switch. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a multifunctional cross limiter to solve the technical problem of low applicability of traditional laser limiters that are installed in conjunction with cross limiters.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multifunctional cross limiter, comprising a limiter body, the limiter body being cylindrical in shape, and a detection mechanism being provided on the outer side, the detection mechanism including a detection device, a mounting ring being fixedly provided on the outer surface of the limiter body, a slide rail groove being provided on the inner side of the mounting ring, and a mounting seat being slidably engaged with the inner side of the slide rail groove by a slider, the detection device being rotatably connected to the mounting seat by a rotating shaft.

[0006] By adopting the above technical solution, and through the cooperation of the slider and the slide rail groove, the position of the detection device can be flexibly adjusted on the mounting ring on the outside of the limiter body. This breaks the limitation of the fixed installation position of the traditional laser limiter. Users can slide the detection device to the optimal position according to the actual installation environment to meet specific detection needs.

[0007] Furthermore, a mounting plate is fixedly provided on one side of the mounting base, and a fastening bolt is threaded onto the mounting plate and abuts against the mounting ring to limit the position of the mounting base and the detection device.

[0008] By adopting the above technical solution, the fastening bolts can be tightly abutted against the mounting ring, thereby effectively limiting the position of the mounting base and the detection device connected thereto. This ensures that the detection device can be stably maintained in the required position after being adjusted, and will not easily shift due to external factors.

[0009] Furthermore, a laser emission port is provided on one side of the detection device, and a base plate is fixedly provided at the bottom of the limiter body, and the base plate is bolted to the external pre-installation point.

[0010] By adopting the above technical solution, the laser emission port is one of the core components of the laser limiter. It is responsible for emitting a laser beam to detect the position of mechanical equipment, enabling the laser limiter to achieve non-contact limit protection, improving the accuracy and reliability of limit protection. At the same time, the position and angle of the laser emission port can be precisely controlled by adjusting the detection device, thereby meeting the limit detection needs in different scenarios.

[0011] Furthermore, a locking mechanism is provided between the mounting base and the detection device to limit the rotation angle between the mounting base and the detection device.

[0012] By adopting the above technical solution, when the detection device rotates to a specific angle, the locking block and the slot are tightly engaged, thereby effectively limiting the further rotation of the detection device and ensuring that the detection device can remain stable at the required angle and will not easily deviate due to external factors, thus improving the measurement accuracy and stability of the laser limiter.

[0013] Furthermore, the engaging mechanism includes several slots and blocks, and the slots and blocks engage with each other. The slots are arranged in an equidistant ring along the central axis of the mounting base, and the blocks have a hemispherical structure.

[0014] By adopting the above technical solution, the detection device can align and engage with a slot at regular intervals during rotation, thereby ensuring that the detection device can stably stay at these preset angles, which greatly improves the accuracy and stability of the laser limiter during the measurement process.

[0015] Furthermore, a top cover is bolted to the top of the limiter body, and a turntable is rotatably mounted on the top of the top cover. A first limit rod and a second limit rod are fixedly mounted on the turntable, and the first limit rod and the second limit rod form a cross structure.

[0016] By adopting the above technical solution, the top cover can not only protect the internal mechanical components of the limiter from external environmental interference, such as dust and moisture, but also enhance the overall stability of the limiter through its robust structure, ensuring that the limiter can maintain a good working condition during long-term use and reducing the failure rate caused by environmental factors.

[0017] Furthermore, a cable outlet hole is provided on one side of the limiter body to provide a connection port for the power cable and the data cable.

[0018] By adopting the above technical solution, power cords and data cables are essential connecting components during the installation and use of the cross limit switch. They are responsible for providing power support and data transmission for the limit switch. The design of the cable outlet hole allows these cables to pass through the limit switch body neatly and orderly, avoiding cable clutter and improving the aesthetics and cleanliness of the installation.

[0019] In summary, the present invention has the following main advantages:

[0020] 1. This utility model, through a detection mechanism, flexibly adjusts the installation position of the detection device on the outside of the limiter body by utilizing the sliding characteristics of the slider and the slide rail groove according to the actual installation environment and detection requirements. By tightening the fastening bolts, the detection device is further fixed, enhancing its positional stability. In addition, the detection device can also rotate relative to the mounting base through the rotating shaft to achieve more precise angle adjustment. This series of adjustment mechanisms makes the detection device more flexible and effective in adjusting the installation position, greatly improving the installation convenience and environmental applicability of the laser limiter.

[0021] 2. By setting up a locking mechanism, the locking block and the locking groove of this utility model provide stable support during the rotation of the detection device. When the detection device rotates to the required angle, the locking block will lock into the corresponding locking groove, thereby ensuring the stability of the detection device at that angle. This not only enhances the overall stability of the limiter structure, but also improves the durability and reliability of the detection device. Attached Figure Description

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0030] The embodiments of this utility model will be described below based on its overall structure. Example

[0031] Multifunctional cross limit switch, such as Figure 1-Figure 4As shown, the device includes a limiter body 1, which is cylindrical in shape and has a detection mechanism 6 on its outer side. The detection mechanism 6 includes a detection device 604. A mounting ring 601 is fixedly mounted on the outer surface of the limiter body 1. A slide rail groove 602 is formed on the inner side of the mounting ring 601, and a mounting seat 603 is slidably engaged with the inner side of the slide rail groove 602 by a slider 606. The detection device 604 and the mounting seat 603 are rotatably connected by a rotating shaft. Through the cooperation of the slider 606 and the slide rail groove 602, the detection device 604 is mounted on the mounting ring 601 on the outer side of the limiter body 1. The flexible sliding adjustment of position 04 breaks the limitation of the fixed installation position of traditional laser limiters. Users can slide the detection device 604 to the optimal position according to the actual installation environment to meet specific detection needs. At the same time, the relative rotation between the detection device 604 and the mounting base 603 is realized by using the rotating shaft 609, which further improves the angle adjustability of the detection device 604. This allows users to more accurately align the detection point by rotating the detection device 604 on the basis of sliding adjustment, thereby increasing the flexibility of the detection range and meeting the limit detection needs in various scenarios.

[0032] See Figure 3 , Figure 4 A mounting plate 607 is fixedly installed on one side of the mounting base 603, and a fastening bolt 608 is threaded onto the mounting plate 607 and abuts against the mounting ring 601. This is used to limit the position of the mounting base 603 and the detection device 604. The fastening bolt 608 can abut tightly against the mounting ring 601, thereby effectively limiting the position of the mounting base 603 and the detection device 604 connected to it. This ensures that after the detection device 604 is adjusted to the required position, it can be stably maintained in that position and will not easily shift due to external factors. At the same time, the abutment between the fastening bolt 608 and the mounting ring 601 also enhances the stability of the entire mounting structure. During the operation of the laser limiter, the detection device 604 needs to accurately emit and receive laser beams to achieve precise control of the position of the mechanical equipment.

[0033] See Figure 3 , Figure 4A laser emission port 605 is provided on one side of the detection device 604, and a base plate 8 is fixedly provided at the bottom of the limiter body 1. The base plate 8 is bolted to the external pre-installation point. The laser emission port 605 is one of the core components of the laser limiter. It is responsible for emitting a laser beam to detect the position of the mechanical equipment, so that the laser limiter can achieve non-contact limit protection, improving the accuracy and reliability of limit protection. At the same time, the position and angle of the laser emission port 605 can be precisely controlled by adjusting the detection device 604, thereby meeting the limit detection needs in different scenarios. Meanwhile, the base plate 8 fixedly provided at the bottom of the limiter body 1 provides a stable installation foundation for the laser limiter and the cross limiter. Through the bolt connection between the base plate 8 and the external pre-installation point, the laser limiter can be firmly installed in the working environment and will not easily move or fall off due to external factors. Example

[0034] See Figure 4 A locking mechanism 7 is provided between the mounting base 603 and the detection device 604 to limit the rotation angle of the mounting base 603 and the detection device 604. When the detection device 604 rotates to a specific angle, the locking block 702 and the locking groove 701 are tightly engaged, thereby effectively limiting the further rotation of the detection device 604 and ensuring that the detection device 604 can remain stable at the required angle and will not easily deviate due to external factors. This improves the measurement accuracy and stability of the laser limiter. At the same time, the locking mechanism 7 also enhances the connection strength between the mounting base 603 and the detection device 604. During the operation of the laser limiter, the detection device 604 needs to continuously emit and receive laser beams to achieve precise control of the position of the mechanical equipment. The presence of the locking mechanism 7 makes the connection between the mounting base 603 and the detection device 604 more secure.

[0035] See Figure 3 , Figure 4 The engaging mechanism 7 includes several slots 701 and blocks 702, with the slots 701 engaging with the blocks 702. The slots 701 are arranged in an equidistant ring along the central axis of the mounting base 603, and the blocks 702 have a hemispherical structure. This allows the detection device 604 to align with and engage with a slot 701 at regular intervals during rotation, ensuring that the detection device 604 can stably remain at these preset angles. This greatly improves the accuracy and stability of the laser limiter during measurement. At the same time, the hemispherical design of the blocks 702 not only facilitates the smooth sliding of the blocks 702 into the slots 701 and engagement, but also provides uniform contact pressure during engagement, enhancing the stability of engagement. The hemispherical structure allows the blocks 702 to automatically adjust their position when subjected to external forces to adapt to the shape of the slots 701, thereby maintaining a stable engagement state.

[0036] See Figure 1 , Figure 2 The top of the limiter body 1 is bolted to a top cover 2, and a turntable 3 is rotatably mounted on the top of the top cover 2. A first limit rod 401 and a second limit rod 402 are fixedly mounted on the turntable 3, and the first limit rod 401 and the second limit rod 402 form a cross structure. The top cover 2 not only protects the internal mechanical parts of the limiter from external environmental interference, such as dust and moisture, but also enhances the overall stability of the limiter through its robust structure, ensuring that the limiter can maintain a good working condition during long-term use and reducing the failure rate caused by environmental factors. At the same time, the turntable 3 rotatably mounted on the top of the top cover 2, and the cross structure formed by the first limit rod 401 and the second limit rod 402 fixedly mounted on the turntable 3, provide the limiter with a flexible and precise limiting function.

[0037] See Figure 1 The limit switch body 1 has a cable outlet hole 5 on one side to provide a connection port for the power cable and data cable. During the installation and use of the cross limit switch, the power cable and data cable are essential connecting components. They are responsible for providing power support and data transmission for the limit switch. The design of the cable outlet hole 5 allows these cables to pass through the limit switch body 1 neatly and orderly, avoiding cable messiness and improving the aesthetics and cleanliness of the installation. At the same time, the cable outlet hole 5 also plays a role in protecting the cables. During the long-term operation of the laser limit switch, the power cable and data cable may be affected or damaged by external factors, such as friction and pulling.

[0038] The implementation principle of this utility model is as follows: First, the base plate 8 is bolted to the pre-installed position on the outside using bolts, so that the external push rod can effectively push the first limit rod 401 and the second limit rod 402. Then, according to the actual installation environment and in conjunction with the point to be detected by the detection device 604, the mounting base 603 and the detection device 604 can be slid to any point on the outer mounting ring 601 of the limiter body 1 by sliding the slider 606 and the slide rail groove 602. Then, the fastening bolt 608 is tightened to fix the position of the detection device 604, thereby improving the installation position flexibility of the detection device 604 relative to the limiter body 1. Subsequently, it can be... The detection device 604 and the mounting base 603 are rotated relative to each other via the rotating shaft 609, thereby further adjusting the adjustability of the detection device 604. Based on the above adjustment process, compared with the traditional and relatively simple installation method, the detection device 604 of this application has more flexible and effective installation position adjustment, thereby improving the applicability of the installation environment of the traditional laser limiter. During the rotation of the detection device 604, the engagement state of the locking block 702 and the locking groove 701 can be used to increase the rotation resistance of the detection device 604. When the detection device 604 rotates to a certain angle, the engagement of the locking block 702 and the locking groove 701 can improve the stability of the installation structure of the detection device 604.
