[0030] In the industrial silicon smelting industry, a rail-mounted aircraft belt trolley is often used in the process of unloading and transferring materials. The trolley moves back and forth on a specific track to transfer raw materials in different bins of a C-shaped material shed. During operation, if there are obstacles on the track or if an operator accidentally walks onto the track, the rail-mounted aircraft belt trolley needs to be manually operated to decelerate the trolley. This may result in the inability to decelerate the trolley in a timely manner, leading to collisions with obstacles or operators, thus posing a significant safety hazard during the operation.
[0031] Please refer to Figure 1 and Figure 2, the present utility model proposes a transportation system, including a track, a transportation trolley and a rangefinder. A deceleration sensor is provided on the track; the transportation trolley is provided with track wheels, and the track wheels are slidably mounted on the track. The transportation trolley includes a receiver, a controller and a driving motor. The receiver is used to receive the signal sent by the deceleration sensor. Both the receiver and the driving motor are signal-connected to the controller, and the driving motor is transmission-connected to the track wheels; the rangefinder is provided on the transportation trolley, and the rangefinder is used to detect the distance between the transportation trolley and an obstacle. The rangefinder is signal-connected to the deceleration sensor. Specifically, the track wheels on the transportation trolley are slidably mounted on the track, so that the transportation trolley will reciprocate on the track. Different positions of materials are transported by the transportation trolley. A rangefinder and a receiver are provided on the transportation trolley. When the transportation trolley is transporting on the track, if there is an obstacle on the track or an operator accidentally enters the track, the rangefinder will measure the distance between the transportation trolley and the obstacle or the operator. When the distance between the transportation trolley and the obstacle or the operator is greater than the first preset value, the transportation trolley runs at the current running speed. When the rangefinder measures that the distance between the transportation trolley and the obstacle or the operator is less than the first preset value and greater than the second preset value, at this time, the transportation trolley needs to decelerate. Then the deceleration sensor will detect the current speed of the transportation trolley, and then the receiver on the transportation trolley will receive the data detected by the deceleration sensor and then transmit it to the controller. The controller increases the braking force of the driving motor based on the data provided by the deceleration sensor to achieve the required deceleration effect. During this process, the rangefinder continuously detects the distance between the transportation trolley and the obstacle or the operator. When the rangefinder measures that the distance between the current transportation trolley and the obstacle or the operator is less than the second preset value, the deceleration sensor detects the current running speed of the transportation trolley, and the receiver on the transportation trolley receives the data detected by the deceleration sensor and then transmits it to the controller. The controller further increases the braking force of the driving motor based on the data provided by the deceleration sensor, so that the transportation trolley stops running, preventing the transportation trolley from colliding with the obstacle or the operator, protecting the safety of the operator, and preventing the transportation trolley from being damaged; in the embodiment, by setting a rangefinder to detect whether there is an obstacle or an operator in the transportation direction of the transportation trolley, and then by the cooperation of the deceleration sensor, the receiver and the driving motor to increase the braking force, so as to realize the deceleration or stop of the transportation trolley, and monitor in real time whether there is an obstacle or an operator in front of the transportation trolley, so as to prevent the situation that the transportation trolley cannot be decelerated in time, resulting in the injury of the operator or the damage of the transportation trolley, ensuring the safety of the operator and increasing the service life of the transportation trolley.
[0032] Please refer to Figure 1 and Figure 2, in one embodiment, the number of deceleration sensors and rangefinders is two. The two rangefinders are respectively arranged at both ends of the transport trolley along the length direction of the track, and the two deceleration sensors are arranged at both ends of the track at intervals. Specifically, two deceleration sensors are arranged at intervals on the track, and the two deceleration sensors are arranged at both ends of the track. Then, a rangefinder is arranged at each end of the transport trolley. In this way, when the transport trolley moves back and forth, whether there are obstacles or operators on the track can be detected in both directions, so as to ensure the safety during operation when the transport trolley moves back and forth, and reduce potential safety hazards in both directions of movement.
[0033] Please refer to Figure 1 and Figure 2 , in one embodiment, the transport system further includes limit posts. The number of limit posts is two, and the two limit posts are respectively arranged at both ends of the track. The limit posts are used to abut against the transport trolley. By arranging two limit posts, when the transport trolley runs to abut against one limit post, it means that it has reached the limit in this direction. The operator takes out the materials in the transport trolley, then adds the materials to be transported, drives the transport trolley to move in the reverse direction, and then the transport trolley runs to abut against the other limit post, which means that it has reached the limit in this direction. The operator takes out the materials in the transport trolley and then puts in the materials to be transported. In this way, by such a setting, it can prevent the transport trolley from rushing out of the track, thus avoiding the situation where the transport system fails.
[0034] Please refer to Figure 1 and Figure 2 , in one embodiment, buffer pads are arranged at both ends of the transport trolley. The buffer pads are used to abut against the limit posts. Specifically, when the transport trolley runs to the limit in one direction, the buffer pads on the transport trolley will abut against the limit posts at this time, buffering the collision between the transport trolley and the limit posts, protecting the transport trolley from being damaged. The operator takes out the materials in the transport trolley, then adds the materials to be transported, drives the transport trolley to move in the reverse direction, and then the transport trolley runs to the limit in the other direction. The buffer pads on the other side of the transport trolley will abut against the limit posts, buffering the collision between the transport trolley and the limit posts, protecting the transport trolley from being damaged. The operator takes out the materials in the transport trolley and then puts in the materials to be transported. In this way, by arranging the buffer pads, buffering can be carried out to protect the transport trolley from being damaged due to collision.
[0035] In one embodiment, the buffer pad is a rubber pad. The rubber pad has good elasticity, can effectively absorb impact force and vibration, and reduce damage to mechanical equipment or structures. High-quality rubber pads have good wear resistance and anti-aging characteristics, can be used in harsh environments for a long time without being easily damaged. Rubber pads can also maintain their physical properties within a wide temperature range, suitable for use in different climate conditions. Compared with metal or other materials, rubber pads have a lower cost and can provide good buffering effects, so they have a high cost performance. Rubber materials are easy to cut and form, can be customized into various shapes and sizes according to actual needs, which is convenient for installation and replacement. Many rubber pads are made of natural rubber or synthetic rubber, and these materials can be recycled and reused, reducing environmental pollution. Compared with metal materials, rubber pads have a smaller density and lighter weight, and will not increase the overall weight burden of the equipment. Rubber pads can effectively reduce the noise generated during collisions and improve the comfort of the environment.
[0036] Please refer to Figure 3 and Figure 4 , in one embodiment, chutes are formed at both ends of the transport trolley along the vertical direction. The transport system further includes two sliding brackets, which are respectively slidably installed in the two chutes, and two rangefinders are respectively installed on the two sliding brackets. By providing the chutes, the sliding brackets can slide along the chutes, and since the chutes are arranged along the vertical direction, the height of the sliding brackets can be adjusted, thereby adjusting the height of the rangefinders to achieve adjustment of different measurement ranges.
[0037] Please refer to Figure 3 and Figure 4 , in one embodiment, the sliding bracket includes a pin shaft, a rotating member and a base. The base is slidably installed in the chute. The rotating member is formed with a first rotating hole, and the base is formed with a second rotating hole. The pin shaft passes through the first rotating hole and is rotatably installed in the second rotating hole. The rotating member is connected to the rangefinder; by providing such a contact structure, the rotating member can rotate around the pin shaft, thereby adjusting the orientation of the measuring end of the rangefinder, and thus achieving adjustment of the measurement angle.
[0038] Please refer to Figure 3 and Figure 4 , in one embodiment, the rotating member includes a first connecting rod and a second connecting rod. The first connecting rod is formed with a telescopic hole, and the second connecting rod is telescopically arranged in the telescopic hole. The first rotating hole is arranged on the first connecting rod, and the second connecting rod is connected to the rangefinder; according to different ranging requirements, the operator can extend or retract the second connecting rod from the telescopic hole, so that the rangefinder can be extended or retracted, thereby achieving adjustment of the measurement range of the rangefinder.
[0039] Please refer to Figure 3 and Figure 4, in one embodiment, the first connecting rod is formed with a first adjustment hole communicating with the telescopic hole, the second connecting rod is provided with a second adjustment hole, and the transportation system further includes a threaded fastener. The threaded fastener is installed in the second adjustment hole through the first adjustment hole to fix the first connecting rod and the second connecting rod to each other. By setting this structure, the first connecting rod and the second connecting rod can be firmly connected, and at the same time, it is convenient for disassembly, replacement and maintenance.
[0040] Please refer to Figure 3 and Figure 4 , in one embodiment, the number of the first adjustment holes is multiple, the number of the second adjustment holes is multiple, and the threaded fastener is at least one. The threaded fastener is installed in one of the second adjustment holes through one of the first adjustment holes. When it is necessary to adjust the measurement range of the point rangefinder, the operator takes out the threaded fastener from the first adjustment hole and the second adjustment hole, then extends the second connecting member out of the first connecting member until the rangefinder extends to a suitable position, and then passes the threaded fastener through one of the first adjustment holes and one of the second adjustment holes, so as to lock the first connecting member and the second connecting member. At the same time, the adjustment distance can be obtained according to the distance between each first adjustment hole. By setting this structure, the adjustment can be made according to the required measurement range.
