Description

Technical Field

[0001] This application relates to the field of weighing sensor technology, specifically to an intermittent load-bearing structure for a weighing sensor. Background Technology

[0002] A load cell is a device that converts a mass signal into a measurable electrical signal output. It is typically used to measure the weight of an object and convert this weight information into an electrical signal, such as voltage or current, so that it can be read and displayed by electronic scales or other measuring devices.

[0003] When existing weighing equipment is used to weigh dump trucks, the tilting tail shaft at the rear of the truck bed and the hydraulic cylinder at the front of the truck bed, which are always connected between the frame and the truck bed, make weighing very difficult. At present, there is no perfect weighing solution, and the weighing accuracy is generally very poor. The current mainstream weighing error range in the industry is 10%-15%, which is basically in the stage of qualitative weighing.

[0004] This application aims to provide an intermittent load-bearing structure for a weighing sensor, applicable to on-board weighing of dump trucks and other platforms.

[0005] Searching using keywords such as "weighing sensor", "load", and "load-bearing capacity" yielded no relevant technical solutions.

[0006] Therefore, a new technical solution is needed to solve the above-mentioned technical problems. Utility Model Content

[0007] This application provides an intermittent load-bearing structure for a weighing sensor, including a sensor body, a lower support connected to the lower part of the sensor body, and an upper support provided on the upper part of the sensor body. The sensor body and the upper support are in line contact when in operation.

[0008] As a preferred embodiment, the sensor body is connected to the lower bracket by bolts.

[0009] As a preferred embodiment, the sensor body has a sensor body bolt hole, and the lower bracket has a lower bracket bolt hole at a position corresponding to the sensor body bolt hole. Bolts are installed in the sensor body bolt hole and the lower bracket bolt hole.

[0010] As a preferred embodiment, the sensor body bolt holes and the lower bracket bolt holes are both two in number.

[0011] As a preferred embodiment, the sensor body has an arc-shaped groove at the top center, and the lower part of the upper bracket has a semi-circular cylindrical protrusion that mates with the arc-shaped groove.

[0012] As a preferred embodiment, the diameter of the arc groove is larger than the diameter of the semi-circular cylindrical protrusion.

[0013] As a preferred embodiment, the lower support includes a lower vertical plate, a lower horizontal plate is fixed to the top of the lower vertical plate, the lower vertical plate has multiple lower mounting holes, and the lower horizontal plate has lower support bolt holes.

[0014] As a preferred embodiment, multiple reinforcing plates are provided between the lower vertical plate and the lower horizontal plate.

[0015] As a preferred embodiment, the upper support includes an upper vertical plate with multiple upper mounting holes, and a semi-circular cylindrical protrusion is fixedly provided on one side of the upper vertical plate.

[0016] As a preferred embodiment, the upper part of the protruding semi-circular cylinder is provided with a mounting base, which is connected to the upper vertical plate.

[0017] In this application, the weight of the truck bed is exerted by the semi-circular cylindrical protrusion of the upper support on the arc groove of the lower support. The arc concentrates the force at the midpoint, allowing all the load to be concentrated on the sensor body at one point. This facilitates stable and accurate weighing results and provides an automatic balancing effect. Furthermore, since the contact with the upper support is linear and not fixed, this application ensures both uniform load distribution on the truck bed when it is laid flat and the ability to detach the truck bed at any time.

[0019] The following is in conjunction with the appendix Figure 1 Appendix Figure 2 The specific embodiments of this utility model will be described in detail below. It should be noted that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model. Example 1

[0020] This application provides an intermittent load-bearing structure for a weighing sensor, including a sensor body 1. A lower support 3 is connected to the lower part of the sensor body 1 via bolts 2. More specifically, the sensor body 1 has sensor body bolt holes 4, and the lower support 3 has lower support bolt holes 5 at positions corresponding to the sensor body bolt holes 4. Bolts 2 are installed in both the sensor body bolt holes 4 and the lower support bolt holes 5. There are two bolt holes in each type of sensor body and lower support bolt holes 5, arranged symmetrically about a center. The upper part of the sensor body 1 is provided with… The upper bracket 6 and the sensor body 1 are in line contact when in operation. More specifically, the sensor body 1 has an arc-shaped groove 7 at the top center, and the lower part of the upper bracket 6 has a semi-circular cylindrical protrusion 8 that mates with the arc-shaped groove 7. The two are in line contact when in operation. The semi-circular cylindrical protrusion 8 is integrally formed with the upper bracket 6. Preferably, the diameter of the arc-shaped groove 7 is larger than the diameter of the semi-circular cylindrical protrusion 8, specifically 3mm-7mm, more specifically 5mm.

[0021] It should be noted that during installation, the entire carriage needs to be raised by approximately 5mm-10mm. After installation, the horizontal tilt angle of the carriage will increase by 0.2°-0.4°, which generally will not affect the normal use of the vehicle. If you do not want the horizontal tilt angle to increase, you can add a shim of appropriate height between the axle seat and the carriage. Technicians can choose according to the specific situation.

[0022] In this application, the weight of the truck bed is exerted by the semi-circular cylindrical protrusion 8 of the upper support 6 onto the arc groove 7 of the lower support 3. The arc concentrates the force at the midpoint, allowing all the load to be concentrated on the sensor body 1, which facilitates stable and accurate weighing results and provides an automatic balancing effect. In addition, since the contact with the upper support 6 is linear and not fixed, this application can ensure uniform load distribution of the truck bed when it is laid flat, and also ensure that the truck bed can be separated at any time. When the truck bed is laid flat, the hinge and hydraulic cylinder are in a floating state, and the load is applied to the sensor body. When the truck bed is raised, the sensor body is no longer in contact with the upper support, and the hydraulic cylinder and hinge bear the load. Example 2

[0023] This embodiment describes the structure of the upper support 6 and the lower support 3: The lower support 3 includes a lower vertical plate 9, and a lower horizontal plate 10 is fixed to the top of the lower vertical plate 9. The lower vertical plate 9 and the lower horizontal plate 10 are preferably rectangular. The lower vertical plate 9 has multiple lower mounting holes 11 for fixing to the vehicle frame. The lower horizontal plate 10 has two lower support bolt holes 5. The lower horizontal plate 10 contacts the lower part of the sensor body 1. Preferably, multiple reinforcing plates 12 are provided between the lower vertical plate 9 and the lower horizontal plate 10. The reinforcing plates 12 are preferably triangular to improve the stability of the lower support 3. The lower vertical plate 9, the lower horizontal plate 10, and the reinforcing plates 12 are connected by welding or other methods.

[0024] The upper support 6 includes an upper vertical plate 13, which is preferably rectangular. The upper vertical plate 13 has multiple upper mounting holes 14 for fixing to the carriage. A semi-circular cylindrical protrusion 8 is fixed on one side of the upper vertical plate 13. To improve stability, a mounting seat 15 is provided on the upper part of the semi-circular cylindrical protrusion 8. The mounting seat 15 and the semi-circular cylindrical protrusion 8 are integrally formed. The mounting seat 15 and the upper vertical plate 13 can be connected by integral forming or by welding.

[0025] In summary, due to the adoption of the above technical solution, in this application, the weight of the truck body is exerted by the semi-circular cylindrical protrusion 8 of the upper support 6 on the arc groove 7 of the lower support 3. The arc concentrates the force at the midpoint, concentrating all the load on the sensor body 1, which facilitates stable and accurate weighing results and has an automatic balancing effect. In addition, since it is in linear contact with the upper support 6 and is not fixedly connected, this application can ensure both uniform load distribution of the truck body when it is laid flat and the ability to separate the truck body at any time.

[0026] This application is mainly used for weighing tipper trucks, which can ensure that the truck body is evenly loaded when it is laid flat, and that the truck body can be separated at any time. It can also be used for weighing other platforms.
