Abstract
Description
Technical Field
[0001] This utility model relates to the field of weighing technology, specifically, to a lateral adjustment device for a double weighbridge and a double weighbridge. Background Technology
[0002] Heavy-duty mining vehicles (with a load capacity of over 100t) are often equipped with dual-unit weighbridges due to their large size and wide wheelbase. This means that a weighbridge is independently mounted on each side of the vehicle. While this design solves the weighing and measurement problem for large mining vehicles, issues can arise during actual use, such as… Figure 1 As shown, the inward tilt of wheel A creates an outward thrust on the double weighbridge. With long-term use, this causes abnormal stress on the bottom sensor of the weighbridge and increased wear, resulting in inaccurate measurement. Utility Model Content
[0003] The purpose of this utility model is to provide a lateral adjustment device for a double weighbridge and a double weighbridge, in order to solve the problem in the prior art that the weighbridge is subjected to outward thrust during use, resulting in abnormal force on the bottom sensor of the weighbridge and accelerated wear, leading to inaccurate measurement.
[0004] The present invention solves the above problems through the following technical solution:
[0005] A lateral adjustment device for a double weighbridge includes an adjustment mechanism, with a connector at each end of the adjustment mechanism, and a fixing member hinged to each connector. The fixing member is used to connect to the weighing body of the double weighbridge.
[0006] This device uses hinged fasteners to compensate for longitudinal stress on the weighbridge body, preventing abnormal stress and accelerated wear on the bottom sensors caused by outward thrust during use. The adjustment mechanism adjusts the distance between the two connecting parts, limiting the connection of the double-unit weighbridge. Fine-tuning is possible without affecting the weighing capacity.
[0007] Furthermore, the adjustment mechanism is an adjusting screw.
[0008] Furthermore, the threads on both sides of the adjusting screw have opposite directions of rotation. Simply rotating the adjusting screw allows for increasing or decreasing the distance between the pull rods, thereby achieving connection and limiting of the scale bodies on both sides. Because the thread adjustment range is small, fine-tuning can be achieved without affecting the weighing capacity of the scale body.
[0009] Furthermore, the fixing element is an ear hole plate.
[0010] Furthermore, the ear plate is used for welding to the side of the double-unit weighbridge body.
[0011] Furthermore, the connector includes a pull rod and a positioning pin. One end of the pull rod has a pin hole that mates with the positioning pin, and the pull rod is hinged to the ear plate via the positioning pin. The hinged connection between the pull rod and the ear plate via the positioning pin enables longitudinal compensation.
[0012] A double weighbridge includes two weighing bodies, each of which is connected to a fixing element in a lateral adjustment device for a double weighbridge.
[0013] Compared with the prior art, this utility model has the following advantages and beneficial effects:
[0014] (1) This utility model provides a lateral limiting and adjustment device for a double weighbridge, which solves the problem of lateral force on the weighbridge and reduces the abnormal load on the bottom sensor.
[0015] (2) This utility model is easy to install and adjust, and will not affect the symmetry and measurement accuracy. Attached Figure Description

[0021] The present invention will be further described in detail below with reference to the embodiments, but the implementation of the present invention is not limited thereto.
[0022] Example 1:
[0023] Combined with appendix Figure 2 and Figure 3 As shown, a lateral adjustment device for a double weighbridge includes an adjustment mechanism, with a connector at each end of the adjustment mechanism, and a fixing member hinged to each connector. The fixing member is used to connect to the weighing body 1 of the double weighbridge.
[0024] This device uses a connecting component and a hinged fixing component to achieve longitudinal compensation with the weighing body 1, preventing the weighbridge from being subjected to outward thrust during use, which could cause abnormal stress on the bottom sensor and accelerate wear. The adjustment mechanism is used to adjust the distance between the two connecting components, achieving connection limit for the double weighing body 1. Fine-tuning is possible without affecting the weighing capacity of the weighing body 1.
[0025] Furthermore, the adjustment mechanism is an adjusting screw 4.
[0026] Furthermore, the threads on both sides of the adjusting screw 4 have opposite directions of rotation. Simply rotating the adjusting screw 4 allows for the increase or decrease of the distance between the pull rods 3, thereby achieving the connection limit for the two sides of the weighing body 1. Because the thread adjustment range is small, fine-tuning can be achieved without affecting the weighing capacity of the weighing body 1.
[0027] Furthermore, the fixing element is an ear hole plate 2.
[0028] Furthermore, the ear hole plate 2 is used to weld to the side of the weighing body 1 of the double weighbridge.
[0029] Furthermore, the connecting component includes a pull rod 3 and a positioning pin 5. One end of the pull rod 3 is provided with a pin hole that mates with the positioning pin 5. The pull rod 3 is hinged to the ear plate 2 via the positioning pin 5. The hinged connection between the pull rod 3 and the ear plate 2 via the positioning pin 5 enables longitudinal compensation.
[0030] Example 2:
[0031] like Figure 4 As shown, a double weighbridge includes two weighing bodies 1, each of which is connected to a fixing component in a lateral adjustment device for a double weighbridge.
[0032] Although the present invention has been described herein with reference to illustrative embodiments, the above embodiments are merely preferred embodiments of the present invention, and the implementation of the present invention is not limited to the above embodiments. It should be understood that those skilled in the art can design many other modifications and implementations, which will fall within the scope and spirit of the principles disclosed in this application.
