Description

Technical Field

[0001] This utility model relates to a tilt detection system, specifically a tilt detection system for a four-sided balancing crane. Background Technology

[0002] In the material handling process of industries such as aluminum profiles, a common method is to use a crane to drive a four-way balancer, which is then connected to the material frame via four slings. The structure of this lifting system mainly relies on the crane's hoisting mechanism, the balancer's lifting equipment, and the slings themselves.

[0003] Currently, determining whether all slings are reliably engaged or completely disengaged relies entirely on the visual observation and personal responsibility of the crane operator. Existing lifting systems lack a physical structure that automatically detects their own balance and mechanically interlocks in case of abnormalities.

[0004] Therefore, when operators fail to check the sling status due to inattention, the existing lifting device structure cannot detect the risk itself. If lifting is attempted while some slings are not properly attached or released, uneven stress on the material frame will occur, causing the balancer to tilt. Because there is no automatic stop mechanism in the structure, this tilt cannot be effectively detected and the dangerous action cannot be stopped immediately, ultimately leading to the material frame overturning, resulting in the scrapping of the substrate and even serious personal injury accidents. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings and defects in the existing technology by providing a tilt detection system for a four-sided balance crane. This utility model constructs an automatic anti-tilt system consisting entirely of hardware.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a tilt detection system for a four-sided balancing crane, comprising a balancing crane body, side connecting plates fixedly connected to the four ends of the outer wall of the balancing crane body, lifting straps installed below the side connecting plates, a central horizontal rib welded to the middle of the balancing crane body, a crane hook welded to the top of the central horizontal rib, movable guide rails installed on both sides of the inner wall of the balancing crane body, a tilt switch mounting assembly slidably connected to the movable guide rails, and a tilt detection component installed on the outer end of the tilt switch mounting assembly; the tilt detection component contains a tilt switch capable of detecting tilt and a wireless transmission module capable of transmitting signals.

[0007] Furthermore, the movable guide rail includes a guide rail body, on which a movable through groove and a limiting groove are provided, and the movable through groove is a T-shaped through groove.

[0008] Furthermore, the tilt switch mounting assembly includes a mounting body, a T-shaped rod is mounted on the upper end of one side of the mounting body, and a threaded rod is threadedly mounted on the lower part of the mounting body.

[0009] Furthermore, the tilt detection component also includes a junction box body, on which bolt holes are provided, and the tilt switch and the wireless transmission module are both installed inside the junction box body. A power module for power supply is provided inside the junction box body.

[0010] Furthermore, the tilt switch is a mechanical tilt switch that can activate the circuit when a set tilt angle is reached.

[0011] Furthermore, the tilt detection components are provided in four groups, with two groups arranged on both sides of the two moving guide rails respectively.

[0012] Furthermore, it also includes a wireless receiving module installed on the vehicle, which is electrically connected to the wireless transmitting module. The output of the wireless receiving module is connected to a relay, and the normally closed contact of the relay is configured to be connected in series to the coil circuit of the vehicle's lifting contactor.

[0013] After adopting the above technical solution, the beneficial effects of this utility model are as follows: This utility model has the following advantages: 1. Significantly Enhanced Safety and Reliability: This invention incorporates tilt switches fixed within the four corner cavities of the four-sided balance crane, constructing a distributed mechanical tilt detection network. When the lifting equipment tilts in any direction due to a sling issue, at least one tilt switch is triggered. Through hard-wired and wireless signal transmission, a relay action is ultimately activated, physically cutting off the power supply to the crane's lifting contactor coil. This series of interconnected structural designs enables automatic and rapid response to dangerous situations, fundamentally preventing overturning accidents.

[0014] 2. Compact structure with minimal impact on existing equipment: All new components (tilt switch, wireless transmitter module, waterproof junction box) are fixed using the cavity on the balance crane body and the existing mounting surface, without requiring large-scale modifications to the original critical structure. The entire supplementary system occupies little space, has a reasonable installation location, and does not interfere with the original normal operating functions of the lifting equipment.

[0015] 3. Easy to install and implement: The components used in this utility model are mostly standard parts or mature modules, and the components are mainly physically connected through power lines and connectors. The installation and fixing methods at the balance hoist end and the overhead crane electrical box end are simple, and the assembly and wiring process of the overall system is simple, which facilitates quick on-site installation and subsequent maintenance.

[0016] 4. Low cost and outstanding economic benefits: The core components of this protection system are all common and inexpensive industrial parts available on the market. The hardware structure of the entire system has extremely low cost, but provides very significant security protection. It solves major safety and quality hazards with minimal hardware investment, and has extremely high cost performance.

[0017] 5. Highly responsive and stable: Since the core detection and execution components are all purely mechanical or basic electronic components, their operation does not depend on complex program algorithms. They have a fast response speed, strong anti-interference ability, and high working stability, making them very suitable for long-term stable operation in harsh industrial environments such as vibration and dust.

[0028] See Figures 1-8 As shown, the technical solution adopted in this specific embodiment is as follows: It includes a balance crane body 1, with side connecting plates 6 fixedly connected to the four ends of the outer wall of the balance crane body 1, and lifting straps 7 installed below the side connecting plates 6. A central horizontal rib 2 is welded to the middle of the balance crane body 1, and a crane hook 3 is welded to the top of the central horizontal rib 2. Moving guide rails 5 are installed on both sides of the inner wall of the balance crane body 1. A tilt switch mounting assembly 8 is slidably connected to the moving guide rail 5, and a tilt detection assembly 4 is installed on the outer end of the tilt switch mounting assembly 8. The tilt detection assembly 4 contains a tilt switch 43 capable of detecting the tilt degree and a wireless transmission module 45 capable of transmitting signals.

[0029] More specifically, the movable guide rail 5 includes a guide rail body 52, on which a movable through groove 51 and a limiting groove 53 are provided, and the movable through groove 51 is a T-shaped through groove. The movable through groove 51 can cooperate with the T-shaped rod 82, so that the T-shaped rod 82 can move without falling off, while the limiting groove 53 is used to cooperate with the threaded rod 83.

[0030] More specifically, the tilt switch mounting assembly 8 includes a mounting body 81, a T-shaped rod 82 is mounted on the upper end of one side of the mounting body 81, and a threaded rod 83 is threadedly mounted on the lower part of the mounting body 81.

[0031] More specifically, the tilt detection component 4 also includes a junction box body 41, on which bolt holes 42 are provided. The tilt switch 43 and the wireless transmission module 45 are both installed inside the junction box body 41. A power module 44 for power supply is provided inside the junction box body 41. The junction box body 41 is installed on the mounting body 81 by bolts engaging with the bolt holes 42.

[0032] More specifically, the tilt switch (43) is a mechanical tilt switch that can turn on the circuit when the set tilt angle is reached. The preferred model is csx-sen-360a-15L / U.

[0033] More specifically, there are four tilt detection components 4, arranged in pairs on either side of the two moving guide rails 5. Multiple tilt detection components 4 can form a distributed mechanical tilt detection network.

[0034] More specifically, it also includes a wireless receiving module installed on the vehicle, which is electrically connected to the wireless transmitting module 45. The output of the wireless receiving module is connected to a relay, and the normally closed contact of the relay is configured to be connected in series to the coil circuit of the vehicle's lifting contactor.

[0035] The working principle of this utility model is as follows: When installing this device, the operator can accurately position the tilt detection component 4 by sliding the tilt switch mounting component 8 on the moving guide rail 5.

[0036] The specific operation is as follows: Loosen the threaded rod 83 to disengage it from the limiting groove 53. At this point, the entire mounting assembly can be moved through the sliding engagement of the T-shaped rod 82 and the movable through groove 51. After all four tilt detection components 4 are adjusted to the optimal detection position with the hanger horizontal, retighten the threaded rod 83 so that its top end presses against the limiting groove 53, thus firmly locking the mounting body 81. This structure ensures the accuracy of the detection network layout and that the position remains fixed after installation, guaranteeing long-term reliability.

[0037] During use, if the sling is not fully attached or completely released, the main body 1 of the four-way balance crane will physically tilt. The tilt detection components 4 installed in the four corner cavities of the main body 1 will change position accordingly. The internal mechanical structure of the tilt switch 43 will become conductive due to the tilt, thus connecting the circuit. This conductive signal will trigger the wireless transmitter module 45, which is also fixed to the lifting device, to start working. The wireless transmitter module 45 will send a signal via radio waves to the wireless receiver module installed near the crane's electrical box. Upon receiving the signal, the wireless receiver module will immediately control the relay action in its output circuit. The relay, acting as an electromagnetic switch, will physically open its normally closed contact when energized. Since this normally closed contact is connected in series to the coil control circuit of the crane's lifting contactor, the opening of the contact means cutting off the power supply to the coil. The lifting contactor will release due to de-energization, thereby terminating the crane's lifting action from the power source. The lifting device will stop rising, effectively preventing the overturning accident caused by the continuous tilting of the material frame.

[0038] The above description is only used to illustrate the technical solution of this utility model and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
