Description

Technical Field

[0001] The utility model relates to the technical field of track scales, in particular to a track scale vehicle positioning mechanism. Background Art

[0002] Weighing instruments for weighing the load of railway trucks. There are three types of track scales: static track scales, dynamic track scales and light track scales. They are widely used in factories, mines, metallurgy, foreign trade and railway departments to weigh bulk cargo on trucks. Among them, in the steelmaking industry, static track scales are commonly used, which are used to weigh various raw materials, fuels and finished products. When weighing, the vehicle needs to be completely parked in the weighing area of ​​the track scale. Once the parking position of the vehicle deviates, it is easy to affect the accuracy of weighing. Therefore, in order to ensure the accuracy of each weighing, some places arrange sensing devices on both sides of the track scale. By setting laser transmitters and laser receivers on both sides of the track scale, it monitors whether the vehicle is completely parked in the weighing area. However, in the production workshops of steelmaking and coking, since they need to transport coal, ore, etc. during work, there is often dust in the environment. These dusts are easily adsorbed on the laser transmitter and laser receiver. If they are not cleaned for a long time, it is easy to affect the normal sensing work of the above equipment, and the irregular cleaning of the staff also increases the extra workload.

[0014] In order to more clearly understand the above-mentioned purposes, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0015] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0016] like Figure 1-3As shown, a track scale vehicle positioning mechanism described in this embodiment includes a weighing track 1, a front guide rail 2 and a rear guide rail 3 are laid at both ends of the weighing track 1, and mounting columns 4 are respectively arranged at both ends of the weighing tracks 1 on both sides, and the mounting columns 4 on both sides are symmetrically arranged in pairs, and the mounting columns 4 are arranged on the outside of each weighing track 1. A warning light 5 is arranged on the top of each mounting column 4, a laser transmitter 8 is arranged on the side wall of the mounting column 4 on one side, and a laser receiver 9 is arranged on the side wall of the mounting column 4 on the other side. The laser transmitter 8 and the laser receiver 9 are arranged opposite to each other, and the rays emitted by the laser transmitter 8 on one side are received by the laser receiver 9 on the other side. When a vehicle passes through the blocking laser signal, the warning light 5 can be controlled to light up, and a cleaning component 6 for cleaning the laser transmitter 8 and the laser receiver 9 is also provided on the mounting column 4, and a sensing device 7 for controlling the start of the cleaning component 6 is also provided on one side of the front guide rail 2.

[0017] A protective cover 10 is provided on the side wall of the mounting column 4 , and the laser transmitter 8 and the laser receiver 9 are both mounted in the protective cover 10 , and the transmitting head of the laser transmitter 8 and the receiving head of the laser receiver 9 are both extended out of the protective cover 10 .

[0018] The cleaning assembly 6 includes a rotating rod 6a arranged on the outside of the laser emitter 8 and the laser receiver 9. Each rotating rod 6a is provided with a cleaning brush 6b on the side facing the laser emitter 8 and the laser receiver 9, that is, the cleaning brush 6b is arranged toward the side of the protective cover 10, and the cleaning brush 6b is respectively attached to the emitting head of the laser emitter 8 and the receiving head of the laser receiver 9.

[0019] A driving motor 11 is disposed below the protective cover 10 , and an end of the rotating rod 6 a is connected to a rotating shaft of the driving motor 11 .

[0020] A mounting rod 12 is provided at one side of the front guide rail 2 , and the sensing device 7 is mounted on the mounting rod 12 , and the sensing device 7 is arranged toward one side of the front guide rail 2 .

[0021] Preferably, the sensing device 7 is a microwave sensor.

[0022] The working principle of the utility model is as follows: first, to maintain the normal operation of each laser transmitter 9, laser receiver 9 and induction device 7, the vehicle will move from the front guide rail 2 to the weighing track 1. When the vehicle passes the position of the induction device 7, the microwave signal emitted by the induction device 7 will be blocked, so that it controls each cleaning component 6 on the mounting column 4 to work. The driving motor 11 rotates several times, and at this time, its rotating shaft rotates with the rotating rod 6a. When the rotating rod 6a rotates, the cleaning brush 6b thereon will continuously clean the transmitting head of the laser transmitter 8 and the receiving head of the signal receiver, thereby removing the dust thereon and ensuring that the signal equipment can operate normally. After the driving motor 11 has worked for a period of time, the rotating rod 6a will stop at a position away from the signal equipment. When the vehicle enters the weighing track 1, the vehicle will first cut off the laser signal emitted by the laser transmitter 9 on the side of the front guide rail 2. At this time, the warning light 5 on the mounting column 4 on this side lights up. As the vehicle continues to travel onto the weighing track, the laser emitted by the laser transmitter 8 on the side of the front guide rail 2 will be re-emitted to the corresponding laser receiver 9. At this time, the warning light 5 on this side goes out. When the vehicle enters the position between the laser transmitters 8 on both sides and all the warning lights 5 are in the off state, it proves that the vehicle has entered the weighing area and can perform weighing operations normally. Once the vehicle travels beyond the weighing area, the laser rays on the side of the rear guide rail 3 will be blocked. At this time, the warning light 5 on this side will light up, and the vehicle only needs to be backed up to the area between the laser transmitters 8 on both sides.
