Description

Technical Field

[0001] This utility model belongs to the field of weighbridge technology, specifically relating to a sunken weighbridge structure. Background Technology

[0002] A weighbridge (also known as a truck scale) is a large weighing instrument used to weigh vehicles and goods. It mainly consists of a platform, load cells, a display instrument, and a data processing system. It is widely used in logistics, transportation, industrial and mining enterprises, and ports. Its working principle involves the sensors converting weight into electrical signals, which are then processed by the instrument to display precise values. It features high precision, strong load-bearing capacity, and impact resistance, making it a key piece of equipment for trade settlement, overload detection, and production process control.

[0003] A known authorized patent with application number 202222856069.7 discloses a sunken weighbridge: a weighbridge body, an installation assembly, and a ring beam. The weighbridge body is fixedly installed inside the installation assembly, with its load-bearing surface facing upwards. The installation assembly is fixedly installed inside the pit, and the ring beam is located between the installation assembly and the pit. The weighbridge body, the outer wall of the pit, and the installation assembly are all on the same horizontal plane. With this structure, when weighing begins, the worker places the weight on the load-bearing surface of the weighbridge body. At this time, the horizontal force on the weighbridge body is zero, avoiding horizontal impact from the weight. Simultaneously, when the weight begins to move, the friction between the weight and the weighbridge body is transferred to the ring beam, thus preventing the weighbridge body from loosening after prolonged use.

[0004] However, in implementing the relevant technology, the following problems were found with the above technical solution: it is inconvenient to limit the position of the vehicle during use, which may cause the vehicle to drive out of the weighbridge and affect the weighing. In addition, it is difficult to ensure that the structure of the weighbridge is not damaged during some special transportation of oversized and overweight vehicles. Therefore, a sunken weighbridge structure is proposed to solve the above problems. Utility Model Content

[0005] This utility model proposes a sunken weighbridge structure, which solves the problems in related technologies where it is inconvenient to limit the position of vehicles during use, vehicles are prone to drive out of the weighbridge, affecting weighing, and it is difficult to ensure that the weighbridge structure is not damaged during some special transportation of oversized and overweight vehicles.

[0006] The technical solution of this utility model is as follows: a sunken weighbridge structure, including: a base, a weighbridge body, a measuring device and a hydraulic rod, wherein the base has multiple mounting grooves inside, the bottom of the mounting groove is provided with an elastic bottom, and the upper surface of the elastic bottom is provided with a measuring device;

[0007] A weighing body is installed above the measuring device;

[0008] Multiple hydraulic rods are fixedly connected inside the base, and multiple lifting frames are fixedly connected to the output ends of the hydraulic rods.

[0009] Preferably, a horizontal plate is fixedly connected to the top of the lifting frame, and an inclined plate is rotatably connected to one side of the horizontal plate.

[0010] Preferably, the weighing body includes a contact surface, a measuring layer is fixedly connected to the lower surface of the contact surface, an overload layer is provided on the lower surface of the measuring layer, one side of the inclined plate is in contact with the contact surface, and the overload layer is made of sleepers.

[0011] Preferably, the measuring device includes a housing, inside which a pressure sensor is fixedly connected, and a top block is fixedly connected to the measuring end of the pressure sensor, with the top block in contact with the measuring layer.

[0012] Preferably, a plurality of vision sensors are fixedly connected to the upper wall of the base, and the vision sensors are located on both sides of the weighing body.

[0013] Preferably, the inclined plate has gentle slopes at both ends, and the width of the horizontal plate covers the gap between the weighing body and the base.

[0014] The working principle and beneficial effects of this utility model are as follows:

[0015] The inclined plate, which rotates and connects with the horizontal plate, prevents damage to the tires caused by the unreasonable design of the limit device when a vehicle enters. The inclined design also makes it less likely for the vehicle to lose control and drive out to either side. The hydraulic rod design allows the inclined plate to be in a horizontal state when the hydraulic rod retracts, cooperating with the horizontal plate to cover the gap between the weighbridge base and the platform, thus preventing the tires of extra-wide special vehicles from getting stuck in the gap when they enter.

[0020] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0021] Implementation

[0022] Please see Figure 1 -2, a sunken weighbridge structure, including: a base 1, a weighbridge body 2, a measuring device 3 and a hydraulic rod 5, the base 1 has a plurality of mounting grooves 11 inside, the bottom of the mounting grooves 11 is provided with an elastic bottom 4, and the upper surface of the elastic bottom 4 is provided with the measuring device 3.

[0023] A weighing body 2 is installed above the measuring device 3;

[0024] Multiple hydraulic rods 5 are fixedly connected inside the base 1, and multiple lifting frames 6 are fixedly connected to the output end of the hydraulic rods 5.

[0025] The technical solution provided in this embodiment is as follows: In use, the hydraulic rod is first raised. After being raised, the tilting plate 8 will be tilted as the horizontal plate 7 is raised. When the vehicle enters, the tilting limiting device can effectively limit the vehicle, preventing the vehicle from being outside the detection point. It works simultaneously with the vision sensor 10. The vision sensor 10 observes the vehicle's entry. The two sets of vision sensors 10 distinguish whether the front wheels and rear wheels have completely entered the weighing area. After the vehicle has completely entered and stopped, the weight of the vehicle is transmitted to the weighing body 2. Pressure sensor 301 is used to weigh vehicles. When an overweight special vehicle enters, the elastic base 4 will deform elastically upon receiving the weight, causing the height of the weighing body 2 to decrease. After decreasing to a certain level, the overload layer 203 will come into contact with the base 1, and the base 1 will directly bear the weight, thus preventing damage to the measuring device 3. When an oversized vehicle enters, the hydraulic rod 5 is lowered, so that the contact surface 201 between the inclined base 8 and the weighing body 2 is in a horizontal state, and the horizontal plate 7 covers the gap between the weighing body 2 and the base 1 to prevent the vehicle from sinking in.

[0026] Furthermore, a horizontal plate 7 is fixedly connected to the top of the lifting frame 6, and an inclined plate 8 is rotatably connected to one side of the horizontal plate 7.

[0027] Specifically, by setting up an inclined plate 8 that is rotatably connected to the horizontal plate 7, the inclined plate 8 can change a certain angle according to the elevation of the horizontal plate 7, so that it has a good effect on limiting various vehicles.

[0028] Furthermore, the weighing body 2 includes a contact surface 201, a measuring layer 202 is fixedly connected to the lower surface of the contact surface 201, an overload layer 203 is provided on the lower surface of the measuring layer 202, one side of the inclined plate 8 is in contact with the contact surface 201, and the overload layer 203 is made of sleepers.

[0029] Specifically, the overload layer 203 is designed so that when an overweight special vehicle enters the device, the overload layer 203 can directly transfer the weight to the base 1, preventing the components below from being damaged due to excessive weight.

[0030] Furthermore, the measuring device 3 includes a housing 303, a pressure sensor 301 is fixedly connected inside the housing 303, and a top block 302 is fixedly connected to the measuring end of the pressure sensor 301. The top block 302 is in contact with the measuring layer 202.

[0031] Specifically, by having the top block 302 contact the measuring layer 203, the gravity sensor 301 is prevented from directly contacting the measuring layer 202, thus reducing direct friction of the gravity sensor 301 during use.

[0032] Furthermore, multiple vision sensors 10 are fixedly connected to the upper wall of the base 1, and the vision sensors 10 are located on both sides of the weighing body 2.

[0033] Specifically, the vision sensor 10 is designed to detect whether the front and rear wheels of the vehicle have fully entered the weighbridge, thus avoiding inaccurate measurement results due to incomplete vehicle entry.

[0034] Furthermore, the inclined plate 8 has gentle slopes 9 at both ends, and the width of the horizontal plate 7 covers the gap between the weighing body 2 and the base 1.

[0035] Specifically, the design of the ramp 9 avoids the side protrusions of the inclined plate 8 when it is laid flat, which would restrict vehicle entry and make the vehicle enter more smoothly.

[0036] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
