Description

Technical Field

[0001] This utility model relates to the field of stacker-reclaimer technology, and in particular to a device for detecting the fall of a feed point roller frame and a stacker-reclaimer. Background Technology

[0002] When material from the cantilever conveyor belt descends through the central silo, the drop is approximately 20 meters, resulting in significant impact on the idler rollers at the material drop point of the stacker-reclaimer. If the idler rollers at the drop point break and fall, they can damage the ground conveyor rollers as the stacker-reclaimer moves, and there is also a risk of scratching the conveyor belt, posing a significant equipment hazard.

[0003] The usual approach is to replace the existing welding with high-strength bolt connections to improve the stability of the idler roller structure. However, during operation, there is still a risk of the idler roller frame falling off at the material drop point. If the fall-off is not detected in time, it will further escalate the accident, which urgently needs to be addressed. Utility Model Content

[0004] To address the aforementioned issues, this application provides a device for detecting the falling of a feed roller frame and a stacker-reclaimer.

[0005] This application provides a device for detecting the fall of a feed roller frame at a material discharge point, including rope loops, limit switches, and pull ropes. Multiple rope loops are provided and are respectively connected to multiple feed roller frames at the material discharge point of a stacker-reclaimer. Limit switches are arranged in pairs and are respectively located on both sides of the multiple feed roller frames in the arrangement direction. The limit switches are installed on the body of the stacker-reclaimer. The pull ropes are sequentially threaded through multiple rope loops, and the two ends of the pull ropes are respectively connected to two limit switches, and the pull ropes are in a taut state.

[0006] In some implementations, the rope loop is attached to the bottom side of the roller frame.

[0007] In some implementations, multiple rope loops are distributed sequentially along a straight line.

[0008] In some implementations, when the pull rope is taut, the pull rope is threaded through a rope loop and suspended relative to the rope loop.

[0009] In some implementations, the rope loops are welded to the roller frame.

[0010] In some implementations, the limit switch is bolted to the stacker-reclaimer body.

[0011] In some implementations, the pull cord is made of nylon.

[0012] In some implementations, the pull cord is made of polyester.

[0013] In some implementations, limit switches are used to connect to the control system signals of the stacker-reclaimer.

[0014] A stacker-reclaimer is equipped with the aforementioned drop detection device for the unloading point roller frame.

[0015] The beneficial effects of this application are as follows: It provides a device for detecting the fall of idler rollers at the material discharge point, including rope loops, limit switches, and a pull rope. A rope loop is installed on each of the multiple idler rollers at the material discharge point of the stacker-reclaimer. The pull rope passes through these multiple rope loops, and both ends of the pull rope are connected to two limit switches. The two limit switches are installed on the body of the stacker-reclaimer and are located on opposite sides of the multiple idler rollers in the arrangement direction. This allows the pull rope to span across the multiple idler rollers. During use, the pull rope is taut. When the idler roller at the material discharge point of the stacker-reclaimer has not fallen off, the spatial position of the pull rope remains unchanged. The limit switch has no signal output. When the idler frame at the unloading point of the stacker-reclaimer falls off, the fallen idler frame causes the rope loop to move downward, resulting in a change in the spatial position of the pull rope, which triggers the limit switch. The limit switch then outputs a signal, enabling the detection of whether the belt idler frame at the unloading point of the stacker-reclaimer has fallen off. Using the solution of this application, the simultaneous detection of whether multiple idler frames have fallen off can be achieved. Combined with the relevant control system, automatic alarm can be realized, avoiding the expansion of losses. The overall structure of this solution is simple, practical, and widely applicable. It can also be applied to other belt unloading point areas in the transfer station. Attached Figure Description

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0021] Furthermore, reference numerals and / or reference letters may be repeated in different examples in this application. Such repetition is for simplification and clarity purposes and does not in itself indicate a relationship between the various embodiments and / or settings discussed. In addition, this application provides examples of various specific processes and materials; however, those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0022] This application discloses a device for detecting the falling of a feed roller frame at a material discharge point, hereinafter referred to as "this device". This device is used to detect whether the feed roller frame at the material discharge point of a stacker-reclaimer has fallen off, so as to reduce subsequent losses.

[0023] Please refer to Figure 1 This device includes a rope ring 100, a limit switch 200, and a pull rope 300. Multiple rope rings 100 are provided. Multiple idler frames 20 at the material drop point of the stacker-reclaimer are respectively equipped with rope rings 100. The number of rope rings 100 is not less than the number of idler frames 20. This device can simultaneously detect whether multiple idler frames 20 have fallen off. The number of idler frames 20 detected at the same time can be 3 or more, or less than 3. However, from the perspective of efficiency, the number of idler frames 20 using this device should not be too few.

[0024] Please refer to Figure 1 Multiple rope loops 100 are respectively connected to multiple roller frames 20 at the material drop point of the stacker-reclaimer. Since the multiple roller frames 20 are arranged in sequence, the multiple rope loops 100 are also arranged in sequence. Pull ropes 300 are sequentially threaded through the multiple rope loops 100. The two ends of the pull ropes 300 are respectively connected to two limit switches 200.

[0025] For the pair setting of limit switches 200, please refer to [reference needed]. Figure 1 Two limit switches 200 are located on both sides of the multiple idler frames 20, and these two sides are on both sides of the arrangement direction of the multiple idler frames 20. That is, in the arrangement direction of the multiple idler frames 20, one limit switch 200, multiple idler frames 20, and another limit switch 200 are arranged sequentially. The limit switches 200 are specifically installed on the body of the stacker-reclaimer, and the installation of the limit switches 200 can be achieved by bolt connection.

[0026] After the device is installed, the pull rope 300 spans multiple idler roller frames 20. The length of the pull rope 300 needs to be adjusted to ensure it is taut. If the idler roller frame 20 at the stacker-reclaimer's unloading point has not detached, please refer to... Figure 1 The spatial position of the pull rope 300 remains unchanged, and the limit switch 200 has no signal output. When the idler roller frame 20 at the stacker-reclaimer's unloading point detaches, please refer to... Figure 2The detached idler frame 20 causes the rope ring 100 to move downward, resulting in a change in the spatial position of the pull rope 300, which triggers the limit switch 200. The limit switch 200 outputs a signal to detect whether the belt idler frame 20 at the material unloading point of the stacker-reclaimer has fallen off.

[0027] The proposed solution allows for simultaneous detection of whether multiple idler roller frames 20 have detached. Combined with a relevant control system, automatic alarms can be triggered, preventing further damage. The solution features a simple overall structure, strong practicality, and wide applicability; it can also be applied to other conveyor belt unloading points in transfer stations.

[0028] It should be noted that after this device is put into use, the pull rope 300 should not be too tight. If it is too tight, the roller frame 20 will shake slightly and the limit switch 200 will generate a signal, which is a false alarm. The tension should not be too loose either. If it is too loose, the roller frame 20 will fall and the limit switch 200 will not generate a signal, so the detection cannot be completed.

[0029] In daily production, the inventor often uses a nylon pull cord 300, which is elastic and can smoothly trigger the limit switch 200.

[0030] The material of the pull rope 300 can be expanded to include polyester material, which can also be used in this device.

[0031] In some implementation methods, please refer to Figure 1 The rope loop 100 is connected to the bottom side of the roller frame 20, which allows the pull rope 300 to pass through the bottom side of the roller frame 20, which is beneficial to the installation process of this device.

[0032] In some embodiments, the installation position of the rope loop 100 on the bottom side of the roller frame 20 is selected such that multiple rope loops 100 are distributed sequentially in a straight line, thereby ensuring that the tensioned pull rope 300 is distributed in a straight line after the device is arranged.

[0033] In some embodiments, when the pull rope 300 is taut, the pull rope 300 is threaded through the rope loop 100 and the pull rope 300 is suspended relative to the rope loop 100.

[0034] Regarding the installation of the rope loop 100 on the roller frame 20, it can be connected by welding or by screwing or other methods.

[0035] The signal generated by the limit switch 200 can connect the limit switch 200 to the control system signal of the stacker-reclaimer, and detect whether the idler roller frame has fallen off through the original control system of the stacker-reclaimer.

[0036] This application also protects a stacker-reclaimer equipped with the aforementioned drop point idler frame drop detection device, which can detect whether the idler frame has fallen off at the drop point.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.
