Widely used automatic conveying equipment includes conveyor belts, transport carts, etc. Rail Guide Vehicle is a means of transportation that travels along the rails, with two driving modes: self-drive and other drive. With the development of science and technology, rail guide vehicles are widely used in the field of transportation. Most of today's rail guide vehicles are only responsible for the function of transportation, and basically cannot provide real-time feedback on the weight information of the current goods. If you want to know the weight of the goods, the goods have been weighed before they are transported, and the weight is bound to other data, and then recorded by the rail guide vehicle, so the rail guide vehicle does not have a weighing function at all. Although the weight of the added parts can also be known in this way, it not only increases the process steps of the entire process, but also has limitations on the parts that can be weighed. In the application of the entire industry, there is no rail guide vehicle that can weigh in real time and feedback the weight of the currently received parts. This may cause the goods to be overweight, which will have a great impact on the service life and safety of the equipment, may cause equipment damage, and even lead to accidents. Therefore, it is urgent to design a rail car with a weighing function to solve the above problems. Utility Model Content

[0022] The utility model provides Figure 1-3 A rail car with a weighing function as shown in the figure comprises:

[0023] The driving assembly 100 includes a motor 101, a transmission shaft 102, a chain 103 and a chain 2 104. The middle and both ends of the transmission shaft 102 are provided with bearing seats, and one side of the bearing seats is provided with a sprocket. The chain 103 is meshed and connected with the sprocket in the middle of the transmission shaft 102. The motor 101 drives the transmission shaft 102 to rotate through the chain 103. One side of the transmission shaft 102 is provided with two sprocket seats. The two sprocket seats are respectively arranged corresponding to the sprockets at both ends of the transmission shaft 102 and are connected through the chain 2 104. The transmission shaft 102 drives the two chains 2 104 to rotate synchronously through the sprockets at both ends.

[0024] The walking assembly 200 includes a body 201 and wheels 202. A connecting frame 203 is provided on one side of the bottom of the body 201. The connecting frame 203 is fixedly connected to the two ends of the corresponding chain 104. When the chain 104 rotates, the body 201 can be driven to move together.

[0025] The weighing assembly 300 includes a weighing sensor 301 and a weighing bracket 302. The weighing sensor 301 is fixed on the top of the vehicle body 201. The weighing bracket 302 is arranged directly above the vehicle body 201 in the horizontal direction. Limiting columns 303 are arranged on both sides of the weighing sensor 301. The bottom of the weighing bracket 302 is provided with a first limiting block 304 movably connected to the limiting column 303. A plurality of mounting slots 305 are fixed on the top of the weighing bracket 302 to facilitate the installation of the carrier 500 on the top of the weighing bracket 302. The weight of the carrier 500 and the cargo acts on the weighing sensor 301 through the weighing bracket 302, so as to accurately control and understand the weight of the cargo.

[0026] In addition, there are a number of weighing sensors 301, which are equidistantly distributed on both sides of the top of the vehicle body 201, and the weighing sensors 301 on both sides are symmetrically arranged about the central axis of the vehicle body 201, so that the weight of the carrier 500 and the cargo can be evenly distributed on the weighing sensors 301. The weighing sensors 301 use hydraulic weighing sensors, which have a simple and firm structure and a large measuring range.

[0027] Specifically, two limiting nuts 3031 are fixed to the top of the limiting column 303, and limiting grooves 3041 corresponding to the limiting column 303 are provided on both sides of the first limiting block 304. The top of the limiting column 303 extends into the limiting groove 3041, and one limiting nut 3031 is located inside the limiting groove 3041, and the other limiting nut 3031 is located outside the limiting groove 3041. The spacing between the two limiting nuts 3031 is the same as the groove depth of the limiting groove 3041 and the length of the hydraulic rod of the weighing sensor 301. When the hydraulic rod is compressed to the lowest position, the two limiting nuts 3031 can respectively support and limit the bottom of the limiting groove 3041 and the bottom of the first limiting block 304, which can prevent the weighing sensor 301 from being crushed and extend its service life.

[0028] It is worth mentioning that an alarm device 306 is provided at the bottom of the weighing sensor 301, and the weighing sensor 301, the alarm device 306 and the motor 101 are electrically connected. When the weight measured by the weighing sensor 301 reaches the set value, the alarm device 306 is activated to remind the staff to handle it. At the same time, the motor 101 stops running to prevent the trolley from running overweight and causing damage to other components (such as the track 400, chain, motor 101, weighing bracket 302, etc.). After the alarm processing is completed, if the weight of the goods does not exceed the set weight, the subsequent task will be carried out to deliver the goods to the next step location.

[0029] Specifically, it also includes a track 400, and there are two tracks 400. The two tracks 400 are fixed to the ground by bolts and are respectively arranged corresponding to the wheels 202 located on both sides of the bottom of the vehicle body 201, so that the vehicle body 201 can run smoothly on the track 400 through the wheels 202.

[0030] It should be noted that buffer blocks 401 are fixed at both ends of one side of the track 400, and a second limit block 2011 is provided in the middle of one side of the vehicle body 201. The central axis surfaces of the buffer block 401 and the second limit block 2011 coincide with each other, so that the vehicle body 201 can be limited and buffered when it moves to both ends of the track 400, thereby preventing the vehicle body 201 from rushing out of the track 400 due to untimely braking. Limiting wheels that fit with both sides of the track 400 are also provided on both sides of the wheel 202, which can prevent the vehicle body 201 from shifting during operation and thus avoid derailment.

[0031] Specifically, it also includes a carrier 500, at the bottom of which are fixed a plurality of mounting clips 501, which correspond one-to-one to a plurality of mounting slots 305 and are plugged and fixed, so as to facilitate the installation and removal of the carrier 500, and a plurality of material retaining rods 502 are fixed on one side of the carrier 500, which can effectively prevent the goods from slipping off the carrier 500.

[0032] Working principle: When the rail trolley with weighing function is used, the goods are first placed on the carrier 500, and the weight of the goods acts on the weighing sensor 301 through the weighing bracket 302. When the weight of the goods does not exceed the set value of the weighing sensor 301, the motor 101 is started, and the motor 101 drives the transmission shaft 102 to rotate through the chain 103, and the transmission shaft 102 drives the body 201 to move through the chain 2 104, and then the goods are transported to the designated position. When the weight of the goods exceeds the set value of the weighing sensor 301, the hydraulic rod of the weighing sensor 301 is pressed to the lowest position. At this time, the limiting nut 3031 on the limiting column 303 limits the first limiting block 304 on the weighing bracket 302 to prevent it from continuing to move down and crushing the weighing component 300. At the same time, the alarm device 306 is started and the motor 101 is shut down to remind the staff to deal with it in time, and at the same time prevent the trolley from overloading and damaging other components. The rail trolley with weighing function has advanced design, compact structure and is easy to use. By setting a weighing sensor 301 and a weighing bracket 302, the weight of the goods can be accurately controlled and understood, damage to other machines caused by overweight goods can be avoided, and the safety of the equipment and the service life of the equipment are improved.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
