Description

Technical Field

[0001] This application relates to the technical field of cantilever anti-collision detection, and specifically to a new type of cantilever anti-collision detection and protection device. Background Art

[0002] A cantilever refers to a beam with one end being a fixed support that does not produce axial, vertical displacement, and rotation, and the other end being a free end (capable of generating forces parallel and perpendicular to the axis). It is a relatively typical simplified model in the force analysis of engineering mechanics. In actual engineering analysis, most actual engineering stress components can be simplified into cantilever beams. The characteristics of a cantilever structure include: a lifting device, a pivot, and a connecting member. When using a cantilever, a situation where the cantilever collides with a goods stack may occur. The magnetic problem is solved through a rope bracket. However, when the existing rope bracket collides with a goods stack, it is prone to deformation and failure, and the repair and restoration are repetitive. Secondly, when the rope breaks, the protection fails, and the contact collision between the cantilever and the goods stack cannot be stopped immediately, which will generate stress damage to the reaction forces on the slewing ring gear and the reducer, reducing the service life of key parts. Summary of the Invention

[0003] The purpose of this application is to provide a new type of cantilever anti-collision detection and protection device for the deficiencies of the prior art. Through the settings of an L-shaped long plate, a monitoring component, a rope, and a connecting wire, the ultrasonic sensor sends a protection signal to the control system for the action, immediately stopping the current slewing action, avoiding the contact collision between the cantilever and the goods stack. During maintenance, the moving rope is pulled to make the monitoring component rotate 270 degrees onto the cantilever, and the operator stands in the upper channel of the cantilever for maintenance purposes.

[0004] The technical solution of this application is as follows: A new type of cantilever anti-collision detection and protection device includes a cantilever and a monitoring mechanism arranged outside the cantilever for monitoring the position of the goods stack. An L-shaped long plate for connecting the monitoring mechanism is fixedly arranged above the cantilever. There are multiple groups of L-shaped long plates, and each group of L-shaped long plates is set to two. A rotating rod for connecting the monitoring mechanism is fixedly connected between each group of L-shaped long plates.

[0005] Preferably, the cantilever includes a railing fixedly connected to the cantilever, and a control box is also provided on the cantilever.

[0006] Preferably, the monitoring mechanism includes a monitoring component arranged outside the rotating rod. A rope is arranged on the monitoring component, a connecting wire is arranged on one side of the monitoring component, fixed rings are arranged outside the monitoring component and the connecting wire, and the other ends of multiple groups of connecting wires are commonly connected to a connecting main wire.

[0007] Preferably, the monitoring component includes a rotating ring rotatably connected to the outside of the rotating rod. A connecting rod is fixedly connected to the lower end of the rotating ring. A connecting plate is fixedly connected to the lower end of the connecting rod. A vertical plate is fixedly connected to the upper end of the connecting plate. An ultrasonic sensor is fixedly connected to the upper end of the vertical plate. A rain shield is fixedly connected to one side of the connecting rod.

[0008] Preferably, the ultrasonic sensor is connected to one end of the connecting wire.

[0009] Preferably, the rain shield is arranged directly above the ultrasonic sensor.

[0010] Preferably, the pull rope is fixedly connected above the rain shield, and the other end of the pull rope is fixedly arranged on the railing.

[0011] Preferably, the fixing ring fixes the connecting wire to the outside of the connecting rod.

[0012] Advantages of this application: Through the settings of the L-shaped long plate, the monitoring component, the pull rope, and the connecting wire, before the cantilever is about to contact the goods stack, the ultrasonic sensor senses the approach of the goods stack, and sends a protection signal to the control system through the connecting wire and the main connecting wire, so that the current slewing action stops immediately, avoiding contact collision between the cantilever and the goods stack. During maintenance, pull the pull rope to make the monitoring component rotate 270 degrees around the rotating rod to the cantilever. The operator stands in the upper channel of the cantilever for maintenance, and after the maintenance is completed, it is reset uniformly, eliminating the problem of repeatability in the restoration of maintenance.

Detailed implementation manners

[0020] In order to enable those skilled in the art of this technology to better understand the technical solutions in this application, the following will clearly and completely describe the technical solutions in the embodiments of this application in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0021] The present invention proposes a new type of anti-collision detection and protection device for a cantilever, as Figure 1 shown in the figure, including a cantilever 1 and a monitoring mechanism 3 arranged outside the cantilever 1 for monitoring the position of the goods stack. An L-shaped long plate 2 for connecting the monitoring mechanism 3 is fixedly arranged above the cantilever 1. There are multiple groups of L-shaped long plates 2, and each group of L-shaped long plates 2 is set to two. A rotating rod 21 for connecting the monitoring mechanism 3 is fixedly connected between each group of L-shaped long plates 2.

[0022] The cantilever 1 includes a railing 11 fixedly connected to the cantilever 1, and a control box is also arranged on the cantilever.

[0023] In this embodiment, when the cantilever 1 is used, the cantilever 1 drives the monitoring component 31 to move through the rotating rod 21. When the cantilever 1 moves towards the goods stack to the set safe detection distance of the monitoring component 31, the monitoring component 31 will send a protection signal to the control system, causing the current slewing action to stop immediately, avoiding contact and collision between the cantilever 1 and the goods stack. At this time, the cantilever can rotate in the opposite direction to withdraw from the collision area, eliminating the situation of collision and damage between the support and the goods stack.

[0024] As Figure 4 and Figure 5 shown, the monitoring mechanism 3 includes a monitoring component 31 arranged outside the rotating rod 21. A pull rope 32 for pulling the monitoring component 31 is connected to the monitoring component 31. A connecting wire 33 is arranged on one side of the monitoring component 31. A plurality of fixing rings 34 are arranged outside the monitoring component 31 and the connecting wire 33. The other ends of multiple groups of connecting wires 33 are commonly connected to a connecting main line 4, and one end of the connecting main line 4 is connected to a control box.

[0025] The monitoring component 31 includes a rotating ring 311 rotatably connected to the outside of the rotating rod 21. A connecting rod 312 is fixedly connected to the lower end of the rotating ring 311. A connecting plate 313 is fixedly connected to the lower end of the connecting rod 312. A vertical plate 314 is fixedly connected to the upper end of the connecting plate 313. An ultrasonic sensor 315 is fixedly connected to the upper end of the vertical plate 314. A rain shield 316 is fixedly connected to one side of the connecting rod 312.

[0026] The ultrasonic sensor 315 is connected to one end of the connecting wire 33. After setting the detection distance of the ultrasonic sensor 315, the ultrasonic sensor 315 uses the "echo analysis" principle for accurate distance detection.

[0027] The rain shield 316 is arranged directly above the ultrasonic sensor 315 to prevent the ultrasonic sensor 315 from being damaged by water ingress in rainy days.

[0028] The pull rope 32 is fixedly connected above the rain shield 316 and is used to pull the entire monitoring component 31 to rotate around the rotating rod 21 as the axis. The other end of the pull rope 32 is fixedly arranged on the railing 11.

[0029] The fixing ring 34 fixes the connecting wire 33 to the outside of the connecting rod 312.

[0030] In this embodiment, when the ultrasonic sensor 315 monitors that the distance to the goods stack is relatively close, the signal is transmitted to the control element in the control box through the connecting wire 33 and the connecting main line 4, so that the rotary motion of the cantilever 1 stops immediately. When maintenance is required, directly pull the pull rope 32, so that the monitoring component 31 rotates 270 degrees around the rotating rod 21 to the cantilever 1. The operator stands in the upper channel of the cantilever 1 for maintenance. After the maintenance is completed, it is reset uniformly, eliminating the problem of repeatability in the restoration of maintenance. This device eliminates the problem that the pull rope 32 and the wire threading bracket are often worn and broken for a long time. When the pull rope 32 breaks, the protection fails, and the cantilever 1 and the goods stack cannot stop immediately when they come into contact and collide, which will generate stress damage to the reaction force on the rotary large gear ring and the reducer, reducing the service life of key parts.
