Description

Technical Field

[0001] This utility model relates to the field of weighbridge equipment technology, and in particular to an adaptive weighbridge device with adjustable support feet. Background Technology

[0002] When existing weighbridges are used on sloping ground, they are usually leveled by adjusting the height point by point using adjustable feet or by using a fixed ramp, but this has the following drawbacks: Adjustable feet can only handle slight unevenness, the adjustment process is cumbersome, requires tools and repeated calibration, and on steep ground, the stability is poor due to single-point force. Scales with ramps are limited by the fixed ramp angle and cannot adapt to irregular inclined surfaces, and the equipment is large and has low flexibility. Utility Model Content

[0003] This invention addresses the shortcomings of existing technologies by providing an adaptive weighbridge device with adjustable support feet, effectively solving the problems of poor stability and low flexibility in existing technologies.

[0004] The technical solution adopted by this utility model to solve the above problems is as follows: An adaptive weighbridge device with adjustable support feet includes a base, a weighbridge body mounted on the upper end of the base, and an adaptive support structure at the lower end of the base. The adaptive support structure includes a first support plate and a second support plate disposed at both ends of the base and capable of adaptively deflecting according to the ground inclination. Support feet are rotatably mounted at both ends of the first and second support plates, and limiting blocks corresponding to the first and second support plates are also disposed at both ends of the base.

[0005] Preferably, the adaptive support structure further includes a motor mounted on a base, the output end of the motor being fixedly connected to a worm gear, a mounting rod being rotatably connected to the base, and a worm wheel meshing with the worm gear being fixedly connected to the mounting rod.

[0006] Preferably, a hinge shaft is fixedly connected to each end of the base, and a linkage rod fixedly connected to the mounting rod is rotatably mounted on the hinge shaft. The middle parts of the first support plate and the second support plate are respectively fixedly mounted on the linkage rod.

[0007] Preferably, a rotating shaft block is fixedly connected to both ends of the first support plate and the second support plate, and the support foot is rotatably mounted on the rotating shaft block. The support foot has several anti-slip patterns on the end that contacts the ground.

[0008] Preferably, the limiting blocks are integrally installed at both ends of the hinge shaft, and the limiting blocks are made of high-strength alloy.

[0009] Compared with the prior art, this utility model has the following advantages: 1. The first and second support plates can be flexibly tilted according to the actual slope of the ground. The angle can be finely adjusted by the support feet through the pivot block. This can handle regular slopes as well as irregular ground with local bumps and slight lateral tilts, thus improving flexibility.

[0010] 2. During weighing, the weight of the goods is transferred through the base to the first and second support plates, and then evenly distributed to the four support feet. This avoids the problem of slippage caused by single-point force on existing adjustable support feet. At the same time, the anti-slip texture on the bottom of the support feet further increases the friction with the ground, effectively preventing the device from sliding or shaking during the weighing process, reducing the scale body deviation caused by unstable support, and improving stability.

Detailed Implementation

[0012] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0013] like Figures 1-5 As shown, an adaptive weighbridge device with adjustable support feet includes a base 8. A weighbridge body 1 is installed on the upper end of the base 8, and an adaptive support structure is provided on the lower end of the base 8. The adaptive support structure includes a first support plate 2 and a second support plate 3 disposed at both ends of the base 8 and capable of adaptively deflecting according to the degree of ground inclination. Support feet 13 are rotatably installed at both ends of the first support plate 2 and the second support plate 3, respectively. Limiting blocks 10 corresponding to the first support plate 2 and the second support plate 3 are also provided at both ends of the base.

[0014] The adaptive support structure also includes a motor 4 mounted on a base 8. The output end of the motor 4 is fixedly connected to a worm gear 5. A mounting rod 7 is rotatably connected to the base 8. A worm wheel 6 that meshes with the worm gear 5 is fixedly connected to the mounting rod 7.

[0015] like Figure 2 and 3 As shown, the motor 4 on the base 8 is started, and the output end of the motor 4 drives the worm 5 to rotate. The worm 5 meshes with the worm wheel 6 on the mounting rod 7 to transmit the rotational power of the motor 4 to the mounting rod 7. The mounting rod 7 is rotatably connected to the base 8 and rotates synchronously with the worm wheel 6, thereby driving the linkage rods 11 at both ends to move.

[0016] The two ends of the base 8 are respectively fixedly connected to the hinge shaft 9, and the hinge shaft 9 is respectively rotatably mounted with the linkage rod 11 fixedly connected to the mounting rod 7. The middle parts of the first support plate 2 and the second support plate 3 are respectively fixedly mounted on the linkage rod 11.

[0017] like Figure 3 and 4 As shown, the linkage rod 11 rotates around the hinge shaft 9, and its other end is fixedly connected to the middle of the first support plate 2 and the second support plate 3. Therefore, the linkage rod 11 will drive the first support plate 2 and the second support plate 3 to adaptively deflect according to the direction of the ground inclination.

[0018] The first support plate 2 and the second support plate 3 are respectively fixedly connected to the two ends of the pivot block 12. The support foot 13 is rotatably installed on the pivot block 12. The support foot 13 has a plurality of anti-slip textures 14 on the end that is in contact with the ground.

[0019] like Figure 2 and 3 As shown in Figure 5, the support feet 13 at both ends of the first support plate 2 and the second support plate 3 automatically conform to the ground contour, and the anti-slip texture 14 at the bottom of the support feet 13 directly contacts the ground, increasing friction and preventing the weighbridge body 1 from sliding.

[0020] The limiting block 10 is integrally installed at both ends of the hinge shaft 9, and the limiting block 10 is made of high-strength alloy.

[0021] like Figure 4 As shown, the limiting block 10 restricts the maximum tilt angle of the first support plate 2 and the second support plate 3 to prevent the weighbridge body 1 from becoming unbalanced due to excessive tilting; the limiting block 10 is made of high-strength alloy and is integrally formed with the hinge shaft 9 to improve structural durability.

[0022] The working process of this utility model is as follows: The weighbridge body 1 is placed on the target inclined ground. The first support plate 2 and the second support plate 3 at the lower end of the base 8 hang naturally. The support feet 13 at both ends are rotatably connected to the first support plate 2 and the second support plate 3 through the pivot block 12, automatically conforming to the ground contour. The anti-slip texture 14 at the bottom of the support foot 13 directly contacts the ground, increasing friction and preventing the weighbridge body 1 from sliding. Initial contact with the ground is achieved only through the passive rotation of the support foot 13, adapting to the local unevenness or slight lateral tilt of the ground. The high-strength alloy limiting blocks 10 at both ends of the pivot shaft 9 are in a ready state, only restricting... During subsequent adjustments, the maximum deflection angle is adjusted to prevent excessive tilting. The motor 4 on the base 8 is then activated. The output of motor 4 drives the worm gear 5 to rotate. The worm gear 5 meshes with the worm wheel 6 on the mounting rod 7, transmitting the rotational power of motor 4 to the mounting rod 7. The mounting rod 7 is rotatably connected to the base 8 and rotates synchronously with the worm wheel 6, thereby driving the linkage rods 11 at both ends to move. The linkage rod 11 rotates around the hinge shaft 9, and its other end is fixedly connected to the middle of the first support plate 2 and the second support plate 3. Therefore, the linkage rod 11 will cause the first support plate 2 and the second support plate 3 to adaptively deflect according to the ground tilt direction: if the ground tilts along the length... With the left side lower than the right, motor 4 drives linkage rod 11 to tilt the left end of the first support plate 2 and the second support plate 3 downward and the right end upward until the weighbridge body 1 reaches a horizontal state. During the adjustment process, the support feet 13 continuously make fine adjustments to their angles through the rotating shaft block 12, always maintaining close contact with the ground. When the first support plate 2 and the second support plate 3 tilt to the preset angle, they are limited by the limit block 10 to prevent exceeding the safety range. Motor 4 is turned off, and the self-locking characteristic of the worm gear 6 and worm 5 mechanism can fix the position of the mounting rod 7, thereby locking the tilt angle of the first support plate 2 and the second support plate 3, completing the horizontal calibration, and the vehicle drives into the weighbridge. The weight of the weighbridge body 1 is transferred to the first support plate 2 and the second support plate 3 through the base 8, and then distributed to the four support feet 13 by the first support plate 2 and the second support plate 3. The support feet 13 form a stable contact with the ground through anti-slip texture 14 to avoid slippage or shaking during the weighing process. At the same time, the fixed tilt angle of the first support plate 2 and the second support plate 3 ensures that the weighbridge body 1 always remains horizontal, avoiding weighing errors caused by tilting. The weighbridge body 1 can collect weight data normally in a horizontal state. The force is evenly distributed on each support foot 13, reducing local stress concentration, which not only ensures weighing accuracy, but also extends the service life of the device.
