Description

Technical Field

[0001] This utility model relates to the field of cargo bucket detection technology for freight cableways, and in particular to an automatic alarm device for preventing cargo buckets from being unattached to ropes in freight cableways. Background Technology

[0002] A cableway in a certain area is 9.5 kilometers long with 78 towers. The highest tower is over 45 meters high, and the lowest tower is 5 meters high. It uses a single-line circulating transport system with gravity grips for rope holding. The cableway transports 190 cargo buckets and has three stations (starting station, turning station, and ending station). Cargo buckets passing through the turning station need to be lowered and raised on the ropes. Due to the complex terrain along the cableway route, the large differences in tower height and the significant span between towers, the sag of the steel cables on both sides varies greatly, resulting in significant up-and-down movement during cableway transport. When cargo buckets enter and exit the turning station, speed changes cause frequent derailment and rope malfunctions on the flat rails. If these issues are not addressed promptly, the cableway may be struck by the next moving cargo bucket, leading to an accident.

[0003] The operation of cableway corner stations is usually monitored manually. If the operators are negligent, the cargo bins may not leave the station, which could cause them to collide and even lead to electromechanical accidents. If an accident occurs on the cableway, it will cause serious losses. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies, such as the operation of cableway corner stations, where the operation of cargo buckets is usually monitored manually. If the operators are negligent, cargo buckets may not leave the station, which could lead to collisions or even electromechanical accidents. Such accidents on the cableway can cause serious losses. Therefore, this utility model proposes an automatic alarm device for preventing cargo buckets from being not attached to the rope in freight cableways.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic alarm device for preventing cargo buckets from being unloaded on a freight cableway includes a base, which is welded from two channel steels in an I-shape. The base is fixed to the roof beam of the corner station by steel plates and angle steel. One end of the base is the entrance and the other end is the exit.

[0007] Both the entrance and exit of the base are equipped with detection mechanisms, which can be used to inspect the cargo bins to prevent them from being unsecured.

[0008] In one possible design, the detection mechanism includes a detection plate, a spring, a proximity switch, a trigger plate, a connector, and a hinge. One leaf of the hinge is welded to the bottom of the base, and the other leaf of the hinge is welded to one end of the detection plate. The proximity switch is fixedly mounted on the bottom of the base, and the spring is fixed between the detection plate and the base via the connector.

[0009] In one possible design, the connector includes two mounting plates, which are welded to both ends of the spring. Each mounting plate has through holes at its four corners, and bolts are installed in the through holes. Threaded holes for use with the bolts are provided on both the detection plate and the bottom of the base. The bolts are threadedly connected to the threaded holes.

[0010] In one possible design, the bolt is fitted with a washer to improve the fixing effect.

[0011] In one possible design, the detection mechanism also includes a relay and an audible and visual combination switch installed on the field control box of the corner station.

[0012] In one possible design, the probe plate is arc-shaped.

[0013] In this application, steel plates and angle steel are used to fix the welded base to the roof beam of the corner station. During the fixing process, it is essential to ensure the base is level and stable, with its entrance and exit directions accurately corresponding to the cargo bucket's operating path on the freight cableway. The steel plates and angle steel are welded to the base and have mounting holes, secured with fasteners (e.g., expansion bolts). A relay and a combination of sound and light switches are installed on the corner station's on-site control box, and correct electrical connections are made with the detection mechanism to ensure accurate circuit connections and proper signal transmission and control of the alarm device. (The proximity switch is a DC24V normally open type, installed directly opposite the trigger plate. The distance between it and the signal trigger plate should be such that when the cargo bucket cable gripper enters the station, the trigger plate rotates up and down, and the trigger plate just triggers the proximity switch.) The DC24V power supply is connected in series with the proximity switch and relay coils. The normally open contacts of the relay and the time relay are connected to AC220V... (The power supply is also connected in series). During operation, the cargo bucket runs on the flat rails and generates a forward thrust due to inertia. As the cargo bucket moves forward, the gripper above the cargo bucket pushes the detection plate upward. One end of the detection plate rotates upward via a hinge, causing the trigger plate on the detection plate to approach the proximity switch. After the proximity switch detects the signal, its internal normally open contact closes, completing the circuit and causing the relay to activate. The relay's normally open contact closes, activating the time relay, which then starts timing. When the cargo bucket reaches the exit, the exit device detects the signal, disconnects the power to the time relay, and stops timing, starting the next cycle. If the entry signal is detected but the exit signal is not detected after the timing expires, an alarm signal will be issued to remind the operators to stop the vehicle in time. This timely alarm before the cargo bucket leaves the station reduces the possibility of accidents caused by cargo bucket collisions, reduces the labor intensity of employees, and improves the reliability of the freight cableway's safe operation.

[0014] The beneficial effects of this utility model are as follows:

[0015] This invention relates to an automatic alarm device for preventing cargo buckets from being unattached to ropes on a freight cableway. The device employs detection mechanisms at both the entrance and exit of the base. When a cargo bucket enters the station normally, the cable grip above the bucket pushes a detection plate upwards, causing it to rotate around a hinge. This triggers the plate to approach a proximity switch. Upon detecting the signal, the proximity switch activates a relay, initiating a timing program. When the cargo bucket exits the station, the device at the exit detects the signal and disconnects the relay, stopping the timing. This precise detection method, triggering timing upon entry and stopping timing upon exit, allows for real-time and accurate monitoring of the cargo bucket's operational status at corner stations. This effectively prevents collisions caused by cargo buckets failing to exit the station due to human oversight, significantly improving the safety of freight cableway operations.

[0016] If an entry signal is detected but an exit signal is not detected by the end of the timer, the device will immediately issue an alarm signal to remind operators to stop the vehicle and handle the situation promptly. This timely alarm mechanism can issue a warning at the initial stage of abnormal operation of the cargo bucket, giving operators sufficient time to handle the situation, preventing the accident from escalating further, minimizing potential losses, and ensuring the safety of the freight ropeway equipment and cargo.

[0017] In this utility model, the automatic alarm device for preventing cargo buckets from being unattached to ropes in a freight cableway automatically detects and alarms the operating status of the cargo buckets. This eliminates the need for operators to constantly monitor the cargo buckets, greatly reducing the workload of employees and allowing them to devote more energy to other important tasks.

[0018] Reducing human error: Manual supervision is easily affected by factors such as the mental state and work experience of operators, resulting in a high error rate. In contrast, the device of this invention operates based on mechanical and electrical principles, is unaffected by human factors, and can stably and reliably complete the detection and alarm tasks for the cargo bucket's operating status. This effectively reduces safety accidents caused by human error and improves the overall stability and reliability of the freight cableway operation. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] Example 1

[0031] Reference Figure 1-9 An automatic alarm device comprises a base 1 and detection mechanisms installed at the entrance and exit of the base 1. The device uses these detection mechanisms to monitor the operating status of the cargo bin. When an abnormality is detected, such as the cargo bin failing to exit the station normally, an alarm signal is issued to prevent accidents caused by the cargo bin not being secured by a rope. The base 1 is the fundamental support component of the entire device, welded from two channel steels in an I-beam shape. This structural form gives the base 1 high strength and stability, enabling it to withstand various forces generated during the operation of the cargo bin.

[0032] During the installation of base 1, steel plates and angle steel are used to fix it to the roof beam of the corner station. The steel plates and angle steel are welded to base 1, and mounting holes are made in the steel plates and angle steel. Fasteners such as expansion bolts are used to firmly fix the steel plates and angle steel to the roof beam. During the fixing process, it is necessary to ensure that base 1 is level and stable, and at the same time, ensure that its entrance and exit directions are accurately aligned with the cargo bucket running path of the freight cableway to ensure that the cargo bucket can pass smoothly through the inspection mechanism.

[0033] The testing mechanism includes a detection plate 2, a spring 3, a proximity switch 5, a trigger plate 6, connecting parts, and a hinge 4. In addition, the testing mechanism also includes a relay and a sound-and-light combination switch installed on the corner station's field control box. The relay and sound-and-light combination switch are components of the testing mechanism in terms of electrical control.

[0034] The detector plate 2 is arc-shaped, which makes the contact between the detector plate 2 and the cargo hopper smoother, reduces the resistance during the operation of the cargo hopper, and can better adapt to the running trajectory of the cargo hopper, thus improving the accuracy of detection. At the same time, the detector plate 2 is arc-shaped upward so that it can move freely when the cargo hopper moves in the opposite direction. The detector plate 2 is connected to the base 1 through the hinge 4 and can rotate around the hinge 4.

[0035] Spring 3 is fixed between the detection plate 2 and the base 1 by a connector. The function of spring 3 is to return the detection plate 2 to its initial position after the cargo hopper passes through, so that the next detection can be performed.

[0036] The proximity switch 5 is a normally open DC24V type and is fixedly installed at the bottom of the base 1. Its installation position is directly opposite the trigger plate 6, and the distance between it and the trigger plate 6 has been precisely adjusted so that when the hopper gripper enters the station, the trigger plate 6 rotates up and down to trigger the proximity switch 5.

[0037] The trigger plate 6 is installed on the detection plate 2. When the detection plate 2 rotates, the trigger plate 6 moves accordingly, moving closer to or further away from the proximity switch 5, thereby triggering the proximity switch 5 to generate a signal.

[0038] One of the hinge 4 blades is welded to the bottom of the base 1, and the other blade is welded to one end of the probe plate 2, thus achieving a rotatable connection between the probe plate 2 and the base 1.

[0039] The connector includes two mounting plates 7, which are welded to both ends of the spring 3. Each mounting plate 7 has through holes at its four corners, with bolts 8 inserted in these holes. Threaded holes for use with the bolts 8 are located on the probe plate 2 and the bottom of the base 1. The bolts 8 are threaded into these holes, thus securely fixing the spring 3 between the probe plate 2 and the base 1. To improve the fixing effect, washers are fitted onto the bolts 8. The material and specifications of the spring 3 can be selected according to actual needs, and the connector allows for replacement of the spring 3.

[0040] This application is used in the field of cargo bucket inspection for freight cableways, but it can also be used in other fields applicable to this application.

[0042] refer to Figure 1-9 An improvement upon Embodiment 1: An automatic alarm device for preventing cargo buckets from being unattached to ropes in freight cableways, which is applied in the field of cargo bucket detection in freight cableways.

[0043] The relay and audible / visual combination switch are installed on the field control box of the corner station and are correctly electrically connected to the testing agency. Specifically, the DC24V power supply is connected in series with proximity switch 5 and the relay coil, while the normally open contact of the relay, the time relay, and the AC220V power supply are also connected in series, forming a complete electrical control circuit.

[0044] The model of the sound and light combination switch can be SGBJ-A2-01 New Energy Handy Sound and Light Alarm AC220V Sound and Light Combination Switch. The sound and light combination switch is existing technology, and its working principle will not be described in detail here. Of course, the specific model and specifications can also be selected according to actual needs.

Those skilled in the art can make any selections according to their needs or convenience.

[0046] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
