Description

Technical Field

[0001] This utility model relates to the field of electronic weighing equipment technology, specifically to an electronic truck scale that is easy to assemble and disassemble. Background Technology

[0002] Electronic truck scales (weighbridges) are large-scale weighing devices used for weighing vehicles. Traditional weighbridges typically use an integral welded structure or are bolted for installation, which has the following problems:

[0003] Installation is complicated: Traditional weighbridges require on-site pouring of concrete foundations, which takes a long time to cure (usually more than 7 days), and the sensors need to be leveled during installation, which is time-consuming and labor-intensive.

[0004] Difficult to disassemble: Welded or bolted structures need to be cut or disassembled piece by piece during relocation, which can easily damage the scale body and sensors, resulting in low reuse rate.

[0005] Transportation difficulties: The integrated scale body is large in size and weight, requiring special vehicles for transportation, which results in high costs.

[0006] High maintenance costs: When the sensor or weighing platform is damaged, the entire system needs to be repaired and it is difficult to replace parts. Utility Model Content

[0007] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an electronic truck scale that is easy to assemble and disassemble, which can effectively solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] This utility model provides an electronic truck scale that is easy to assemble and disassemble, comprising two bases, each base having two first insertion cavities on its top, and two insertion holes on opposite sides of each base, and further comprising:

[0010] A connector is provided between two bases. The top of the connector has two second insertion cavities. The bottom center of each of the two second insertion cavities has a square cavity. A handwheel is rotatably installed in each of the two square cavities. Two plugs are telescopically slidably installed on both sides of the connector. When the two handwheels are rotated clockwise, the two corresponding plugs are respectively inserted into the corresponding insertion holes.

[0011] It also includes several connectors, each of which has a socket installed at its bottom. Each of the sockets is detachably inserted into a corresponding first cavity and a second cavity, and the socket inserted into the second cavity presses against a corresponding handwheel.

[0012] It also includes several weighing platforms, each of which can be detachably plugged into the top of its corresponding connector.

[0013] Furthermore, the top slopes of both bases are provided with anti-slip textures, and the distance between the two bases is consistent with the width of the connecting seat.

[0014] Furthermore, the connecting seat is provided with two cavities, and gears are rotatably installed at the bottom of each cavity. The bottom of each handwheel extends through into the corresponding cavity and is vertically fixedly connected to the center of the top of the corresponding gear.

[0015] Furthermore, two racks are meshed on the outer ring walls of both gears, and a connecting rod is connected between each rack and its corresponding plug.

[0016] Furthermore, each of the connectors has a wide-mouth socket on its top, and each of the weighing platforms has two vertically fixed plugs at its bottom, with each plug being inserted into its corresponding wide-mouth socket.

[0017] Furthermore, the top height of several of the weighing platforms is flush with the top height of the two base platforms, and the sides of adjacent weighing platforms are in contact with each other.

[0018] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0019] 1. Quick assembly and disassembly

[0020] The base, connector, and weighing platform all adopt a plug-in structure, eliminating the need for welding or complex bolt fixing. During installation, simply align and insert the components; during disassembly, simply reverse the process. The time for a single assembly or disassembly can be reduced to within 2 hours. The linkage design of the handwheel-driven plug allows the base and connector to be locked by rotating the handwheel without the need for additional tools. The weighing platform and connector use a wide-mouth socket, allowing for a certain degree of deviation and reducing the installation accuracy requirements.

[0021] 2. Dual locking for enhanced stability

[0022] After the connector socket is inserted into the second cavity, it directly presses against the handwheel to prevent it from accidentally reversing, ensuring that the plug is always locked in the socket of the base to prevent loosening when the vehicle runs over it. The gear-rack transmission mechanism makes the plug extend and retract synchronously, and the force is evenly distributed to avoid the scale body tilting due to loosening on one side.

[0023] 3. Modular transportation

[0024] The base, connector, and weighing platform can be transported separately. Each module is lightweight (capable of being under 1 ton), making it suitable for transport by ordinary trucks and reducing logistics costs. The electrical wiring is integrated into the connectors; disassembly only requires plugging and unplugging, eliminating the need to disconnect the wires and preventing damage to the wiring.

[0025] 4. Easy to maintain

[0026] If any component (such as the sensor or weighing platform) is damaged, it can be replaced individually without the need for complete disassembly, reducing maintenance costs. The anti-slip textured base design prevents slippage during installation, improving safety. Attached Figure Description

[0038] The present invention will be further described below with reference to the embodiments.

[0039] Example 1:

[0040] Reference Figure 1-4 This first embodiment of the present invention discloses an easily detachable electronic truck scale, comprising two bases 1, each base 1 having two first insertion cavities 11 on its top, the first insertion cavity 11 having dimensions of 200mm × 150mm × 100mm (length × width × depth). Each base 1 has two insertion holes 12 on opposite sides, the insertion holes 12 having a diameter of 50mm and a depth of 80mm. It also includes a connecting seat 2, disposed between the two bases 1, the connecting seat 2 having two second insertion cavities 21 on its top. The dimensions are 180mm×130mm×90mm. Each of the two second insertion cavities 21 has a square cavity 22 at the center of its bottom. The square cavity 22 has a side length of 100mm and a depth of 60mm. A handwheel 23 is rotatably installed in each of the two square cavities 22. The handwheel 23 has a diameter of 80mm and a thickness of 30mm. Two plugs 26 are telescopically slidably installed on both sides of the connecting seat 2. The plugs 26 have a diameter of 48mm and an extension length of 70mm. When the two handwheels 23 are rotated clockwise, the two corresponding plugs 26 are respectively inserted into the corresponding insertion holes 12.

[0041] It also includes several connectors 3, which are composed of the following structures:

[0042] Load-bearing shell:

[0043] Made of high-strength aluminum alloy (model 6061-T6)

[0044] Dimensions: 300mm (L) × 250mm (W) × 150mm (H)

[0045] The wall thickness is 15mm, and the internal structure is reinforced with ribs.

[0046] Weighing sensor assembly:

[0047] Type: Digital shear beam sensor (4 units / connector)

[0048] Measuring range: 20 tons / unit, accuracy class C3

[0049] Installation method: Embedded installation at the four corners inside the housing;

[0050] Protection rating: IP68

[0051] Signal processing module:

[0052] Integrated 24-bit A / D converter

[0053] Sampling rate: 200 times / second

[0054] Built-in temperature compensation circuit (-30℃~+70℃)

[0055] The mechanical transmission path during weighing according to this utility model is as follows:

[0056] Vehicle load → Weighing platform 4 → Insert rod 41 → Wide-mouth socket 32 ​​→ Connector 3 housing → Weighing sensor elastomer → Base 1

[0057] Each connector 3 has a socket 31 installed at its bottom. The socket 31 measures 170mm × 120mm × 80mm. The sockets 31 are detachably inserted into the corresponding first cavity 11 and second cavity 21. The sockets 31 inserted into the second cavity 21 are pressed against the corresponding handwheel 23 with a pressing pressure of not less than 200N. The system also includes several weighing platforms 4, each measuring 2000mm × 1500mm × 100mm (length × width × height), which are detachably inserted into the top of the corresponding connector 3.

[0058] Example 2:

[0059] Reference Figure 1-4 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: the top slopes of the two bases 1 are provided with anti-slip textures, the spacing between the anti-slip textures is 5mm and the depth is 2mm. The distance between the two bases 1 is consistent with the width of the connecting seat 2. The width of the connecting seat 2 is 500mm. The connecting seat 2 is provided with two cavities, the size of which is 300mm×200mm×150mm. Gears 24 are rotatably installed at the bottom of the two cavities. The module of the gears 24 is 4 and the number of teeth is 20. The bottoms of the two handwheels 23 extend through into the corresponding cavities and are vertically fixed to the top center of the corresponding gears 24. Two racks 25 are meshed on the outer ring walls of the two gears 24. The length of the racks 25 is 200mm and the module matches that of the gears 24. A connecting bent rod is connected between the two racks 25 and the corresponding plugs 26. The diameter of the connecting bent rod is 15mm and the bending radius is 50mm.

[0060] Several connectors 3 are provided with wide-mouth sockets 32 on their tops. The upper opening of the wide-mouth socket 32 ​​is 60mm×60mm, the lower opening is 50mm×50mm, and the depth is 40mm. Several weighing platforms 4 are vertically fixed to their bottoms with two plug rods 41. The plug rods 41 have a diameter of 48mm and a length of 60mm. Several plug rods 41 are respectively inserted into the corresponding wide-mouth sockets 32. The top height of several weighing platforms 4 is flush with the top height of the two bases 1. The height tolerance is controlled within ±1mm. The sides of two adjacent weighing platforms 4 are fitted together, and the fitting gap is no more than 0.5mm.

[0061] The remaining structure is the same as that in Example 1.

[0062] I. Installation Phase

[0063] Step 1: Positioning of Base 1

[0064] Place the two bases 1 parallel to each other on a flat surface, adjust the distance between them to ensure that it matches the width of the connecting seat 2, and the anti-slip texture on the top of the base 1 can prevent displacement.

[0065] Step 2: Tighten connector 2

[0066] Place the connector 2 between the two bases 1, and rotate the handwheel 23 clockwise. The handwheel 23 drives the rack 25 through the gear 24, pushing the plug 26 out and into the socket 12 of the base 1 to achieve initial fixation.

[0067] Step 3: Install connector 3

[0068] Insert the socket 31 at the bottom of the connector 3 into the first cavity 11 of the base 1 or the second cavity 21 of the connector 2. When the socket 31 is inserted into the second cavity 21, its bottom presses against the handwheel 23 to prevent the handwheel 23 from reversing and to ensure that the plug 26 remains locked.

[0069] Step 4: Weighing platform 4 docking

[0070] Insert the plug 41 at the bottom of the weighing platform 4 into the wide-mouth socket 32 ​​of the connector 3. The wide-mouth design allows for a certain deviation, which facilitates quick alignment. After installation, the sides of adjacent weighing platforms 4 fit tightly together, and the top height is flush with the base platform 1, forming a continuous weighing plane.

[0071] II. Weighing Stage

[0072] After the vehicle enters the weighing platform 4, the weight is transferred to the connector 3 through the plug rod 41, and then distributed to the base 1 or the connecting seat 2 through the socket 31. The plug 26 remains stable under the double locking of the gear rack mechanism and the socket 31 to prevent it from loosening during the weighing process.

[0073] III. Disassembly Stage

[0074] Step 1: Remove weighing platform 4

[0075] Lift the weighing platform 4 upwards to disengage the insertion rod 41 from the wide-mouth socket 32 ​​of the connector 3.

[0076] Step 2: Release the connector limit

[0077] Pull out connector 3 to disengage socket 31 from second socket 21 and release pressure on handwheel 23.

[0078] Step 3: Unlock connector 2

[0079] Rotate the handwheel 23 counterclockwise, and the gear 24 will drive the rack 25 to retract the plug 26, causing it to exit the socket 12 of the base 1, thus separating the connector 2 from the base 1.

[0080] Step 4: Modular handling

[0081] Transport the base 1, connecting seat 2, and weighing platform 4 to the new site in modules, and repeat the installation process to quickly put them into use.

[0082] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
