Technical Field

[0001] The utility model relates to the technical field of automobile scales, in particular to an explosion-proof electronic automobile scale. Background Art

[0002] A truck scale, also known as a floor scale, is a large scale installed on the ground. It is usually used to weigh the tonnage of a truck's cargo. It is the main weighing equipment used by factories, mines, businesses, etc. for measuring bulk goods. An explosion-proof electronic truck scale refers to an electronic truck scale made of explosion-proof materials. The main application places of explosion-proof electronic truck scales are some dangerous places, such as flammable and explosive chemical production plants, oil refineries, etc.

[0003] When an explosion-proof electronic truck scale is used to weigh a vehicle, the vehicle needs to be parked on the surface of the truck scale, and the weight is detected by an electronic sensor installed in the truck scale. However, during the parking process, it is difficult for the vehicle to be parked accurately at the most accurate measurement position, and manual guidance is usually required, otherwise it is easy to affect the weighing result. If there is no manual guidance, the vehicle will be parked at the edge of the truck scale surface for a long time, which will also affect the service life of the truck scale. The need for manual guidance will also increase labor costs and the burden on workers, and also increase the risk.

[0004] Therefore, we made improvements to this and proposed an explosion-proof electronic truck scale. Utility Model Content

[0022] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0023] Example: Figures 1 to 4 As shown, the utility model is an explosion-proof electronic truck scale, including an explosion-proof electronic truck scale body 1, the shell of the explosion-proof electronic truck scale body 1 is made of explosion-proof material, and a floor scale sensor 14 is installed inside the explosion-proof electronic truck scale body 1, the model of the floor scale sensor 14 is QS-30T, and the weight of the weighed truck is measured by the floor scale sensor 14, and guide blocks 2 are installed at both ends of the explosion-proof electronic truck scale body 1. The guide blocks 2 are triangular blocks with their inclined surfaces facing upward, and the two inclined surfaces are symmetrical about the explosion-proof electronic truck scale body 1, so that the weighed vehicle can enter and leave the surface of the explosion-proof electronic truck scale body 1 conveniently.

[0024] The explosion-proof electronic automobile scale body 1 is symmetrically provided with mounting frames 6, and the top surface of the mounting frame 6 is rotatably provided with a connecting shaft 8, and a rotating rod 7 is fixedly sleeved on the connecting shaft 8; the rotating rod 7 can rotate with the rotation of the connecting shaft 8, and when it rotates to a horizontal state, it can play a limiting role, which is convenient for guiding the vehicle to stop at a specific position. After the vehicle is weighed, the rotating rod 7 is rotated to a vertical state, which is convenient for the vehicle to leave. The rotating rod 7 replaces manual labor, which can play a role of limiting and reminding, reduce labor costs, and avoid dangers caused by manual labor during the guidance process.

[0025] Gear 1 9 and gear 2 10 are also rotatably arranged in the installation frame 6, and gear 1 9 meshes with gear 2 10 for transmission, and gear 1 9 is fixedly sleeved on the connecting shaft 8. A cavity is opened in the installation frame 6, and a baffle is hinged on the front of the installation frame 6, and a controller is installed on the baffle. A support plate 13 is fixedly arranged horizontally in the cavity, and the bottom end of the connecting shaft 8 rotates through the installation frame 6 and is rotatably arranged on the support plate 13. A forward and reverse motor 12 is also installed in the cavity, and a rotating shaft 11 is fixedly arranged at the output end of the forward and reverse motor 12, and the rotating shaft 11 is rotatably arranged in the cavity, and gear 2 10 is fixedly sleeved on the rotating shaft 11. The forward and reverse motor 12 and the floor scale sensor 14 are both electrically connected to the controller 15.

[0026] A weight sensor is arranged inside the guide block 2 on the surface of the explosion-proof electronic truck scale body 1. The model of the weight sensor is QB-16, and the weight sensor is electrically connected to the controller. When the vehicle enters the surface of the guide block 2 on which the weight sensor is arranged, the weight sensor feeds back a signal to the controller 15. After receiving the signal, the controller 15 starts the forward and reverse motor 12. The forward and reverse motor 12 drives the rotating shaft 11 to rotate, so that the gear 2 10 on the rotating shaft 11 rotates together, and the gear 2 10 meshes with the gear 1 9 to rotate, thereby driving the connecting shaft 8 to rotate, and then the rotating rod 7 rotates to a horizontal state. After that, the vehicle drives to a specific position of the explosion-proof electronic truck scale body 1, and the weight is measured by the floor scale sensor 14 and the signal is fed back to the controller 15. The controller 15 starts the forward and reverse motor 12 again. Through the cooperation between the rotating shaft 11, the gear 2 10, the gear 1 9 and the connecting shaft 8, the rotating rod 7 is rotated to a vertical state, which is convenient for the vehicle to drive away.

[0027] The distance between the two rotating rods 7 is smaller than the width of the explosion-proof electronic truck scale body 1, which can prevent the rotating rods 7 from affecting each other during rotation. There is a gap between the bottom end of the rotating rod 7 and the top surface of the explosion-proof electronic truck scale body 1. The setting of the gap is also convenient for the rotating rod 7 to rotate.

[0028] The bottom ends of both sides of the explosion-proof electronic truck scale body 1 are symmetrically fixed with mounting plates 3, and the two ends of the mounting plates 3 extend to the sides of the two guide blocks 2. A plurality of mounting holes 5 are evenly opened on the mounting plates 3, and a limit column 4 is fixedly installed between adjacent mounting holes 5. The opening of the mounting holes 5 facilitates fixing the mounting plates 3 at a specific position, thereby facilitating the positioning of the explosion-proof electronic truck scale body 1. The setting of the limit column 4 can prevent the vehicle from accidentally driving out of the explosion-proof electronic truck scale body 1 during the weighing process, and can also play a role in limiting and guiding the vehicle during driving.

[0029] During operation, rotating rods 7 are rotatably arranged on both sides of the top surface of the explosion-proof electronic truck scale body 1. When weighing is required, the two rotating rods 7 are rotated to a horizontal state to play a role of limiting and reminding. The vehicle to be weighed only needs to drive close to the rotating rods 7 to ensure that the vehicle is parked in the correct position. After weighing, the rotating rods 7 are rotated to a vertical state to facilitate the truck to leave the top surface of the explosion-proof electronic truck scale body 1. No manual guidance is required in the whole process, which reduces labor costs and avoids accidents during manual guidance.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
