Description

Technical Field

[0001] This utility model relates to the field of truck scale technology, and in particular to a truck scale platform with a U-shaped beam bottom sealing plate reinforcement frame. Background Technology

[0002] A truck scale, also known as a weighbridge, is a weighing device used to weigh large vehicles such as trucks. It mainly consists of a platform, load cells, and a weighing display instrument. The platform is the place where the vehicle is parked for weighing. It is usually made of sturdy steel with sufficient strength and rigidity to withstand the weight of the vehicle. The load cells are installed below the platform and convert the vehicle's weight into an electrical signal. The weighing display instrument receives and processes the signal from the load cells to display the vehicle's weight. When a vehicle drives onto the platform, the platform deforms under the vehicle's weight. The load cells sense this deformation and convert it into an electrical signal proportional to the weight. These electrical signals are transmitted to the weighing display instrument, which processes and calculates the accurate weight of the vehicle.

[0003] In general, to ensure the accuracy of the weighing sensors, truck scales do not have elastic buffer elements under the platform panel to reduce vibration, and therefore do not have a vibration damping effect. In view of this, this paper proposes a truck scale platform with vibration damping function and a U-shaped beam bottom sealing plate reinforcement frame. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that the existing weighing platform does not have a shock-absorbing effect because it does not have an elastic buffer element under the panel. Therefore, this utility model proposes a truck scale platform with a U-shaped beam bottom sealing plate reinforcement frame.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A truck scale platform with a U-shaped beam bottom sealing plate reinforcement frame includes a panel and a U-shaped beam reinforcement frame. The panel is fixedly installed on the top of the U-shaped beam reinforcement frame, and several vertically arranged shock-absorbing legs are evenly distributed and installed on the bottom of the U-shaped beam reinforcement frame.

[0007] The shock-absorbing outrigger includes a lifting push rod and a cylinder. The lower end of the lifting push rod is installed in the air compression chamber of the cylinder through a piston seal. An electric needle valve and an air inlet are connected to the lower part of the air compression chamber. The air inlet is connected to a compressed air tank through a high-pressure solenoid valve.

[0008] Preferably, the cylinder is composed of an explosion-proof cylinder and a base, the lower end of the explosion-proof cylinder is fixedly connected to the upper surface of the base, and the air compression chamber is the inner cavity of the explosion-proof cylinder.

[0009] Preferably, the base has a connection hole connected to the air compression chamber, the air inlet is vertically connected to one side of the connection hole, and the electric needle valve is fixedly installed on the base and communicates with the connection hole therein.

[0010] Preferably, the top end of the lifting push rod is fixedly connected to the lower surface of the top plate and the U-shaped beam reinforcement frame.

[0011] Preferably, a high-pressure diversion valve is provided between the air inlets and the high-pressure solenoid valves of the plurality of shock-absorbing outriggers.

[0012] Preferably, a vision sensor is provided on the upper side of one side of the panel, and the vision sensor is connected to the high-pressure solenoid valve and the electric needle valve via a controller.

[0013] Compared with the prior art, this utility model provides a truck scale platform with a U-shaped beam bottom sealing plate reinforcement frame, which has the following beneficial effects:

[0014] This truck scale platform, reinforced with a U-shaped beam bottom plate, uses vertically telescopic lifting rods and cylinders connected by several shock-absorbing legs to guide the vertical lifting of the platform at multiple points. This effectively prevents uneven force on the top of the platform from causing tilting, thus enhancing the stability of the platform's vertical lifting. Compressed air filling the shock-absorbing legs buffers the impact of the vehicle pressing down on the platform, preventing excessive impact force on the platform and the U-shaped beam reinforcement frame from causing plastic deformation. Furthermore, when the vehicle is fully on the platform and stops for weighing, the vision sensor, via the controller, closes the high-pressure solenoid valve and activates the electric... The needle valve is used to slowly release the compressed air from multiple shock-absorbing outriggers, thereby reducing the speed of the panel's descent. This also serves to reduce the impact of the vehicle's load on the panel and U-beam reinforcement frame, minimizing damage to these components. Simultaneously, the slow descent of the panel and U-beam reinforcement frame also reduces the impact force on the weighing sensors, thus minimizing damage. This process continues until the compressed air in the explosion-proof cylinder is completely released, eliminating the support from the shock-absorbing outriggers and preventing interference with the weighing sensors.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Reference Figure 1-3 A truck scale platform with a U-shaped beam bottom sealing plate reinforcement frame includes a panel 1 and a U-shaped beam reinforcement frame 2. The panel 1 is fixedly installed on the top of the U-shaped beam reinforcement frame 2, and several vertically arranged shock-absorbing legs 3 are evenly distributed and installed on the bottom of the U-shaped beam reinforcement frame 2.

[0022] In this embodiment, the shock-absorbing outrigger 3 includes a lifting push rod 31 and a cylinder. The top end of the lifting push rod 31 is fixedly connected to the lower surface of the top plate 37 and the U-shaped beam reinforcement frame 2. The cylinder is composed of an explosion-proof cylinder 32 and a base 33. The lower end of the explosion-proof cylinder 32 is fixedly connected to the upper surface of the base 33. An air compression chamber is provided inside the explosion-proof cylinder 32, that is, the air compression chamber is the inner cavity of the explosion-proof cylinder 32. A connection hole 38 connected to the air compression chamber is provided above the base 33. The lower end of the lifting push rod 31 is sealed and lifted and installed in the air compression chamber of the cylinder through a piston 36.

[0023] An electric needle valve 34 and an air inlet 35 are connected to the lower part of the air compression chamber. The air inlet 35 is vertically connected to one side of the connection hole 38. The electric needle valve 34 is fixedly installed on the base 33 and is connected to the connection hole 38 therein. The air inlet 35 is connected to a compressed air tank through a high-pressure solenoid valve. A high-pressure diverter valve is connected between the air inlets 35 and the high-pressure solenoid valves in several shock-absorbing legs 3. The compressed air tank is sealed and filled with compressed air, and an air compressor is connected to the air inlet of the compressed air tank.

[0024] In this embodiment, a vision sensor is fixedly installed on one side of the panel 1 via a column. The vision sensor is mainly used to detect whether a car is placed on the panel 1. The vision sensor is connected to the high-pressure solenoid valve and the electric needle valve 34 via a controller. If a car is detected on the panel 1, the high-pressure solenoid valve is closed and the electric needle valve 34 is opened to slowly release the compressed air in the multiple shock-absorbing legs 3, so as to achieve the purpose of slowly lowering the panel 1. If no car is detected on the panel 1, the high-pressure solenoid valve is opened and the electric needle valve 34 is closed to automatically fill the air compression chamber with compressed air. The multiple weighing sensors of the weighing platform, which are vertically supported below the U-shaped beam reinforcement frame 2, support the panel 1, which can effectively reduce the fatigue of the weighing sensors.

[0025] This utility model uses a lifting push rod 31 and a cylinder that are vertically telescopically connected in several shock-absorbing legs 3 to guide the vertical lifting of the panel 1 at multiple points, which can effectively avoid uneven force on the top of the panel 1 and tilting, thereby enhancing the stability of the vertical lifting of the panel 1.

[0026] Before the truck scale platform with the U-shaped beam bottom sealing plate reinforcement frame is loaded with a truck, the panel 1 and the U-shaped beam reinforcement frame 2 are elastically supported by multiple weighing sensors vertically supported below. Then, the visual sensor opens the high-pressure solenoid valve and closes the electric needle valve 34 through the controller to automatically fill the air compression chamber with compressed air, which helps the multiple weighing sensors vertically supported below the U-shaped beam reinforcement frame 2 to support the panel 1, which can effectively reduce the fatigue of the weighing sensors.

[0027] When the car initially drives onto panel 1, the compressed air in several shock-absorbing legs 3 is subjected to compression and deformation again, which can buffer the impact force of the car pressing down on panel 1 and prevent panel 1 and U-shaped beam reinforcement frame 2 from being subjected to excessive impact force and plastic deformation.

[0028] When the vehicle has fully driven onto panel 1 and stops for weighing, the vision sensor closes the high-pressure solenoid valve and opens the electric needle valve 34 via the controller. This allows the compressed air in the multiple shock-absorbing legs 3 to be released slowly and throttled, thus slowing down the descent of panel 1. This also serves to reduce the impact of the vehicle's load on panel 1 and the U-shaped beam reinforcement frame 2 during descent, reducing damage to them. Simultaneously, the slow descent of panel 1 and the U-shaped beam reinforcement frame 2 also reduces the impact force on the weighing sensor, thus minimizing damage. Furthermore, the smaller the outlet of the electric needle valve 34, the slower the air release, and the slower the descent of panel 1, until the compressed air in the explosion-proof cylinder 32 is completely released, losing the support of the shock-absorbing legs 3 on panel 1, and thus not interfering with the weighing sensor.

[0029] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
