[0028] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.
[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.
[0030] It will be appreciated that spatial relationship terms such as "under," "beneath," "below," "under," "above," "above," etc., may be used herein to describe the relationship of an element or feature shown in the figures to other elements or features. It will be appreciated that, in addition to the orientations shown in the figures, spatial relationship terms also include different orientations of the device in use and operation. For example, if the device in the accompanying drawings is flipped, an element or feature described as "under other elements" or "under it" or "under it" will be oriented as being "above" the other elements or features. Thus, the exemplary terms "under" and "under" may include both upper and lower orientations. In addition, the device may also include additional orientations (e.g., rotated 90 degrees or other orientations), and the spatial descriptors used herein are interpreted accordingly.
[0031] It should be noted that when an element is considered to be "connected" to another element, it can be directly connected to the other element, or connected to the other element through an intermediate element. The "connection" in the following embodiments should be understood as "electrical connection", "communication connection", etc. if the connected circuits, modules, units, etc. have electrical signals or data transmission between each other.
[0032] When used herein, the singular forms "a", "an", and "said / the" may also include plural forms, unless the context clearly indicates otherwise. It should also be understood that the terms "include / comprise" or "have" etc. specify the presence of stated features, wholes, steps, operations, components, parts or combinations thereof, but do not exclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts or combinations thereof.
[0033] like Figure 1-5 The illustrated limiting balance beam device is located at the side of the balance beam 14 and includes a connecting portion 1, an ear plate 4, a pin 5 and a latch 6. The connecting part 1 is connected to the side end of the balance beam 14, a groove 2 is provided at the top of the connecting part 1, and a through hole 3 penetrating the groove 2 is provided at the side of the connecting part 1; two groups of ear plates 4 are provided, which are respectively connected to the bottom of the bottom plate 15 and are respectively located on both sides of the connecting part 1. When the cargo box moves downward and returns to its original position, the bottom plate 15 drives the ear plates 4 to move downward, and the ear plates 4 move to both sides of the groove 2 of the connecting part 1; a pin shaft 5 is connected between the two groups of ear plates 4, and during the downward movement of the ear plates 4, the middle pin shaft 5 will be driven to enter the groove 2 until it contacts the bottom; the latch 6 is used to limit the pin shaft 5. After the pin shaft 5 contacts the bottom of the groove 2, the latch 6 is inserted into the through hole 3, the latch 6 passes through the groove 2 and is located above the pin shaft 5, and the latch 6 and the bottom surface of the groove 2 jointly lock the pin shaft 5 at the bottom of the groove 2, so that the upper bottom plate 15, the cargo box and the balance beam 14 form a whole, avoiding the unlocked state of the cargo box and the balance direction in the prior art.
[0034] In order to facilitate the insertion of the pin 6 through the groove 2 into the through hole 3 on the other side, an extension portion 7 is provided on the side of the connecting portion 1 away from the balance beam 14, and a through hole corresponding to the through hole 3 is opened on the extension portion 7. The through hole serves as a fulcrum at the far end. The through hole is located on the extension line of the through hole 3 on both sides of the groove 2. When the pin 6 is inserted into the through hole and the first through hole 3, the pin 6 remains horizontal, and then the pin 6 continues to move inward to maintain a state of accurate docking with the through hole 3 on the other side, without the need for alignment operation.
[0035] The plugging of the latch 6 forms a locked state, and the locked state is lost after being pulled out. The plugging and pulling out of the latch 6 can be handled manually. In order to improve the level of automation, in one embodiment, a hydraulic assembly 8 is provided on the side of the extension 7 away from the balance beam 14, and the latch 6 is provided at the output end of the hydraulic assembly 8, and the plugging and pulling out of the latch 6 is completed by hydraulic control. Furthermore, a connecting plate 11 connected to the balance beam 14 is provided on the side of the connecting part 1, and a proximity switch 10 is provided on the connecting plate 11 at the connecting part 1, so that the driver can obtain information in the cab whether the ear plate 4 (pin shaft 5) has reached the bottom of the groove 2, and whether the latch 6 has been inserted.
[0036] Specifically, a connecting plate 11 connected to a balance beam 14 is provided on the side of the connecting portion 1, and two symmetrical groups of connecting plates 11 are provided. A support plate is connected between the ends of the two groups of connecting plates 11, and the hydraulic assembly 8 is installed on the support plate. A fixing plate 12 is connected to the top of the two groups of ear plates 4, and a reinforcing rib plate 13 is provided on the side of the two groups of ear plates 4.
[0037] In some usage scenarios, after the cargo box falls, it still maintains a small gap with the balance beam 14, so that the pin shaft 5 does not reach the bottom of the groove 2, and the latch 6 collides with the pin shaft 5 during the insertion process. Preferably, an inclined surface 9 is formed at the bottom of the front end of the latch 6, and the inclined surface 9 is inclined downward along the balance beam 14 toward the connecting part 1. The inclined surface 9 can guide the pin shaft 5 to be pressed down, so that the cargo box can be tightly attached to the balance beam 14.
[0038] The device of this solution can be symmetrically arranged at both ends of the balance beam 14.
[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
