Obviously, the described embodiments are only a part of the embodiments of this utility model, rather than all the embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of this utility model.

[0031] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0032] The following will describe in detail some implementation manners of this utility model in conjunction with the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0033] To further elaborate on the technical means and effects adopted by this utility model to achieve the intended utility model purpose, the following will describe in detail the specific implementation manners, structures, features and their effects of this utility model in conjunction with the accompanying drawings and preferred embodiments.

[0034] Please refer to Figures 1-7 , an electric rail type truck scale, including a weighing platform 1, a weighing sensor, a connection component 2, a pulley 3 and a driving component. There are several groups of weighing platforms 1, and adjacent two groups of weighing platforms 1 are connected by the connection component 2. The weighing sensor is arranged on the bottom surface of the weighing platform 1. The pulley 3 is slidably installed at the bottom of the weighing platform 1. The driving component is used to drive the pulley 3 to slide along the bottom surface of the foundation 6.

[0035] The operating principle of the truck scale in this utility model is as follows:

[0036] First, multiple groups of weighing platforms 1 are set on the ground of the foundation 6 and connected by connecting components 2. These weighing platforms 1 form a continuous weighing area for bearing the weight of the vehicle; weighing sensors are installed on the bottom surface of the weighing platforms 1 to accurately measure the weight of the vehicle on the weighing platforms 1; these sensors usually use technologies such as pressure sensors or strain gauges to detect the gravitational force of the vehicle and convert it into an electrical signal; pulley 3 devices are installed at the bottom of the weighing platforms 1 to enable the pulleys 3 to slide smoothly on the bottom surface of the foundation 6, and the driving component is used to drive the pulleys 3 to slide; the vehicle to be weighed enters above the weighing platforms 1 and drives into the weighing area; by starting the driving component, the pulleys 3 begin to slide along the bottom surface of the foundation 6.

[0037] Since multiple groups of weighing platforms 1 are connected together by connecting components 2, the length of the weighing area can be flexibly adjusted and spliced according to actual needs to adapt to vehicles of different sizes. This spliced design enables the electric rail vehicle scale to weigh at different locations, being more flexible and convenient than traditional fixed vehicle scales; since the driving component can drive the pulleys 3 to slide along the bottom surface of the foundation 6, the entire weighing system can be moved to different positions for use. This flexibility enables the electric rail vehicle scale to be quickly deployed at different locations according to actual needs to adapt to the usage requirements of different scenarios; the mobile electric rail vehicle scale can be conveniently installed and used in different places without the installation and disassembly of fixed equipment. This provides a more convenient weighing solution for users, especially in the case of frequent equipment relocation, saving time and labor costs.

[0038] Please refer to Figure 6 and Figure 7, in order to reduce the vibrations and interferences caused by the instability of the weighing platform 1 or external forces, and to ensure the reliability and durability of the weighbridge during long-term use, in one embodiment, mounting grooves 4 are horizontally formed on the end faces of the weighing platform 1 close to each other, and limiting holes 5 are vertically formed in the mounting grooves 4. The connecting assembly 2 includes sliding rods 21, limiting blocks 22, sliding plates 23 and first springs 24. The sliding rods 21 are slidably mounted in the mounting grooves 4, the limiting blocks 22 are arranged at both ends of the sliding rods 21, the limiting blocks 22 are slidably mounted in the limiting holes 5, the sliding plates 23 are mounted on the end faces of the sliding rods 21 away from each other, and both ends of the first springs 24 are abutted against the end faces of the mounting grooves 4 and the sliding plates 23 close to each other. When the weighing platform 1 moves, the sliding rods 21 connect and drive the adjacent two groups of weighing platforms 1 to move. When the weighing platform 1 stops moving, the sliding rods 21 slide along the mounting grooves 4, and the limiting blocks 22 slide along the limiting holes 5, so that the sliding plates 23 compress the first springs 24, realizing the buffering between the adjacent two groups of weighing platforms 1. By using the sliding connection and buffering design, the vibrations and interferences caused by the instability of the weighing platform 1 or external forces are reduced, which helps to improve the stability and accuracy of the weighing process and ensures that the measured weight data is more reliable and accurate; the design of the connecting assembly 2 enables the weighing platform 1 to remain stable during long-term use and can withstand a large amount of movement and pressure, ensuring the reliability and durability of the weighbridge during long-term use.

[0039] Please refer to Figure 1 , in order to effectively control and reduce the frictional force and ensure the smooth operation of the weighing platform 1, in one embodiment, slide rails 7 are provided on the bottom surface of the base 6, the pulleys 3 are slidably mounted on the slide rails 7, and limiting plates 8 are arranged at both ends of the slide rails 7. By slidably mounting the pulleys 3 on the slide rails 7, the smoothness and stability of their sliding can be ensured, enabling the pulleys 3 to slide along the fixed track on the bottom surface of the base 6, effectively controlling and reducing the frictional force, and ensuring the smooth operation of the weighing platform 1; the limiting plates 8 are mounted at both ends of the slide rails 7, and their main function is to limit the sliding range of the pulleys 3, preventing the pulleys 3 from sliding out of the slide rails 7 or exceeding the reasonable range. By setting the sliding limit position of the pulleys 3, the limiting plates 8 ensure that the weighing platform 1 will not exceed the safe range during the moving process, improving the safety and stability of use.

[0040] Please refer to Figure 1 and Figure 2, in order to make the movement process smoother, reduce vibration and interference, in one embodiment, a buffer assembly 9 is further provided on the slide rail 7. The buffer assembly 9 includes a second spring 91 and a buffer plate 92. The two ends of the second spring 91 are respectively connected to the limit plate 8 and the buffer plate 92. The buffer plate 92 has an arc structure that matches the shape of the pulley 3. The buffer assembly 9 and the buffer plate 92 can play a role in buffering and shock absorption during the movement of the weighing platform 1. When the weighing platform 1 moves, the pulley 3 will slide on the slide rail 7. Through the arc shape matching of the buffer assembly 9 and the buffer plate 92, when the pulley 3 contacts the buffer plate 92, it can slow down the speed and buffer the impact, making the movement process smoother and reducing vibration and interference; the buffer assembly 9 and the buffer plate 92 can improve the safety of the electric rail type truck scale. By slowing down the speed and buffering the impact, the damage to the equipment and the weighed object caused by the impact generated by sudden stop or start can be reduced, the probability of accidents is decreased, and the safety of the operator and the equipment is improved.

[0041] Please refer to Figures 1-5 , in order to prevent unnecessary movement and vibration and ensure the safety of the operator, in one embodiment, locking assemblies 10 are provided at both ends of the foundation 6. The locking assembly 10 includes a fixing member 101, a locking member 102 and a locking groove 103. The fixing member 101 is provided at both ends of the weighing platform 1. One end of the locking member 102 is hinged to the inner wall of the foundation 6. The vertical cross-section of the free end of the locking member 102 is conical. The locking groove 103 is fixed to the inner wall of the foundation 6. The locking member 102 is inserted into the locking groove 103 and can slide in the locking groove 103. When the weighing platform 1 moves to a certain position on the slide rail 7, the fixing member 101 will push the locking member 102 to move upward. When the weighing platform 1 moves to the end of the slide rail 7, the gravity will cause the locking member 102 to fall naturally and buckle with the fixing member 101. In this way, the weighing platform 1 is fixed to the end of the slide rail 7. The function of the locking assembly 10 is to ensure that the weighing platform 1 always maintains a stable and fixed position during the measurement process when it is stationary at the end of the slide rail 7, prevent unnecessary movement and vibration, and ensure the accuracy and reliability of the weighing result; the locking assembly 10 can improve the safety of the electric rail type truck scale. By fixing the weighing platform 1 at the end of the slide rail 7, unnecessary displacement or tilt caused by instability during weighing can be avoided, the safety of the operator is ensured, accidents are prevented, and a more reliable weighing result is provided.

[0042] Please participate in Figure 4 and Figure 5, in order to reduce the direct contact between the weighing platform 1 and the inner wall of the foundation 6 and protect the integrity and smoothness of the equipment surface, in one embodiment, rubber cushions 11 are provided at both ends of the weighing platform 1. The rubber cushions 11 can provide an elastic and soft surface. When the weighing platform 1 moves to the end of the slide rail 7, it can play a role in shock absorption and buffering between the weighing platform 1 and the inner wall of the foundation 6. By absorbing the impact and reducing the impact force during collision, the rubber cushions 11 can protect the weighing platform 1 and the inner wall of the foundation 6, reduce the damage and wear of the equipment, and improve the service life of the equipment; the rubber material has certain anti-friction and anti-slip properties. When the weighing platform 1 moves to the end of the slide rail 7, the rubber cushions 11 can reduce the direct contact between the weighing platform 1 and the inner wall of the foundation 6, avoid excessive friction and scratching, and protect the integrity and smoothness of the equipment surface.

[0043] Please refer to Figure 6 and Figure 7 , in order to reduce the risk of the slide rod 21 being bent or broken and reduce the impact and pressure between the weighing platforms 1, in one embodiment, the slide rod 21 slides in the installation groove 4 with a clearance, and the slide plate 23 is in interference fit with the installation groove 4. The slide rod 21 slides in the installation groove 4 with a clearance. When the weighing platform 1 has a certain degree of deviation during the moving process, this setting can reduce the risk of the slide rod 21 being bent or broken. The slide rod 21 can slide freely in the installation groove 4, enabling it to adapt to the slight deformation or deviation of the weighing platform 1, thereby reducing the damage caused by the concentrated force on the rod; the slide plate 23 is in interference fit with the installation groove 4, having a more closely fitting contact, so that the slide plate 23 can better disperse the extrusion force from between two adjacent groups of weighing platforms 1 by squeezing the first spring 24 when the weighing platform 1 stops moving, improving the buffering effect of the connecting component 2, reducing the impact and pressure between the weighing platforms 1, and improving the stability and accuracy of the weighing process.

[0044] In order to prevent the end face of the weighing platform 1 from directly colliding with or rubbing against the inner wall of the foundation 6 and protect the surface of the equipment from damage and wear, in one embodiment, gaps are provided between the two ends of the slide rail 7 and the inner wall of the foundation 6. Since gaps are provided between the two ends of the slide rail 7 and the inner wall of the foundation 6, when the weighing platform 1 moves, it prevents the end face of the weighing platform 1 from directly colliding with or rubbing against the inner wall of the foundation 6, protecting the surface of the equipment from damage and wear; the setting of the gaps makes the maintenance and adjustment of the equipment more convenient. If maintenance or component replacement is required, the gaps can provide sufficient space and flexibility, enabling the operator to easily enter and operate, and perform necessary maintenance and adjustment work to maintain the normal operation and performance of the equipment.

[0045] The above are only the preferred embodiments of the present utility model, and do not impose any formal restrictions on the present utility model. Although the present utility model has been disclosed above with the preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to equivalent embodiments with equivalent changes within the scope of the technical solution of the present utility model by using the technical content disclosed above.
