[0001] This application relates to the field of dump truck technology, and more particularly to a baffle, cargo box and dump truck with automatic tension adjustment. Background Technology

[0002] Articulated dump trucks are used in many scenarios that require cargo box baffles, such as when carrying heavy loads uphill or transporting sand and gravel. To prevent cargo from spilling, baffles are usually installed on the cargo box. The working principle of the baffles is roughly the same: the baffle is usually mounted on a frame, with the middle of the frame hinged to the cargo box. One end of the frame is connected to a fixed point on the vehicle frame with a steel wire rope. The baffle opens and closes by its own weight as the cargo box rises and falls.

[0003] However, due to manufacturing and assembly errors, the actual distances from the rope ends on the left and right sides of the baffle to the frame fixing points are not the same. This results in the steel wire ropes on the left and right sides bearing different tensile forces, thus affecting the service life of the steel wire ropes. Utility Model Content

[0004] This application aims to at least solve one of the technical problems that, due to manufacturing and assembly errors, the actual distances from the rope ends on the left and right sides of the baffle to the frame fixing points are not the same, which leads to different tensile forces on the left and right sides of the wire rope, thus affecting the service life of the wire rope.

[0005] Therefore, this application provides a baffle with automatic tension adjustment. This application employs a novel rope arrangement method, using a single rope that passes through the inside of the vehicle frame, with both ends connected to supports on either side.

BRIEF DESCRIPTION OF DRAWINGS

[0019] In order to more clearly illustrate the technical solutions of the application, the drawings needed in the embodiments will be briefly introduced below, and obviously, other drawings can also be obtained by those skilled in the art without any creative effort on the basis of these drawings.

[0025] To better explain and facilitate understanding of this application, a detailed description of the application is provided below with reference to the accompanying drawings and specific embodiments. The directional terms such as "upper," "lower," "inner," and "outer" mentioned herein are used in conjunction with... Figure 1 The orientation is used as a reference. The position of the baffle 1 relative to the steel pipe 6 is defined as "upper"; the position of the rope 3 relative to the steel pipe 6 is defined as "inner".

[0026] As mentioned above, articulated dump trucks are widely used in construction sites, mines, and other locations. On construction sites, they can be used to transport building materials such as sand and gravel, and cement; in mines, they can be used to transport heavy objects such as ore. Their self-unloading function is achieved through a hydraulic system. The driver can operate the hydraulic system to tilt the cargo box, thereby automatically unloading the goods. This greatly reduces the time and cost of manual unloading and improves work efficiency.

[0027] To prevent goods from spilling, baffles are usually installed on the cargo box, such as... Figure 3 As shown, due to manufacturing and assembly errors, the actual distances from the rope ends on the left and right sides of the baffle to the frame fixing points are not the same. This results in the steel wire ropes on the left and right sides bearing different tensile forces, thus affecting the service life of the steel wire ropes.

[0028] To address at least one of the technical problems existing in the prior art or related technologies, this application provides a baffle, cargo box, and dump truck with automatically adjustable tension. The automatically adjustable baffle includes: a baffle disposed at the first end of a support; the support disposed on both sides of the cargo box, with its middle section hinged to the cargo box; the cargo box hinged to the vehicle frame; and a rope passing through the vehicle frame, with both ends of the rope connected to the second end of the support. This application employs a novel rope arrangement method, using a single rope passing through the inside of the vehicle frame, with both ends connected to the supports on both sides, and a fixed pulley guiding the rope at bends. This rope forms a principle similar to communicating vessels, ensuring that the tension on both sides of the baffle is equal at any given time.

[0029] The following description, with reference to the accompanying drawings, describes a baffle for automatic tension adjustment according to some embodiments provided in this application.

[0030] See Figures 1 to 2 The first aspect of this application provides a tension-adjustable baffle, comprising: a baffle 1 disposed at the first end of a bracket 2; the bracket 2 disposed on both sides of a housing 7, with the middle part of the bracket 2 hinged to the housing 7; the housing 7 hinged to a frame 8; and a rope 3 passing through the frame 8, with both ends of the rope 3 connected to the second end of the bracket 2.

[0031] The rectangular baffle 1 is positioned between the two supports 2 to prevent goods inside the container 7 from falling due to vibration or collision during transport. The first end of each support 2 is connected to the baffle 1, the second end to a rope 3, and the middle is hinged to the container 7, acting as a lever. When the container 7 is not raised, i.e., when it is in a horizontal position, as... Figure 2 As shown, baffle 1 is in a closed state due to its own weight, at which time baffle 1 can block the goods in the box 7; when the box 7 is raised, that is, when the box 7 is in a tilted state, as... Figure 1 As shown, the second end of the support 2 is held by the rope 3. Based on the lever effect, the baffle 1 will open as the box 7 is raised. At this time, the baffle 1 will not block the goods in the box 7, so that the goods are automatically unloaded.

[0032] Because a single rope 3 passes through the inside of the frame 8, with its two ends connected to the supports 2 on both sides, the rope 3 forms a kind of communicating vessel principle, ensuring that the tension on both sides of the baffle 1 is equal at any given time. When the left and right sides of the baffle 1 are subjected to different magnitudes of force, the rope 3 plays a balancing role. Since the rope 3 passes through the frame 8 and connects to the supports 2 on both sides, when one support 2 is subjected to a larger tension, the rope 3 will transmit this tension to the other support 2, thus causing it to also be subjected to a corresponding tension. In this way, the tension on both sides of the baffle 1 will tend to be equal, ensuring the balance and stability of the baffle 1.

[0033] Furthermore, rope 3 can be made of steel wire rope, which is made of multiple high-strength steel wires twisted together, thus having extremely high tensile strength and being able to withstand large loads; at the same time, steel wire rope has good wear resistance and can be used for a long time in harsh environments without easily being damaged.

[0034] In one illustrative embodiment, a steel pipe 6 is provided on the frame 8, and a rope 3 passes through the steel pipe 6 and through the frame 8.

[0035] The steel pipe 6 passes through the frame 8, meaning that the straight line of the steel pipe 6 is perpendicular to the central axis of the frame 8. The steel pipe 6 provides a smooth channel for the rope 3, which not only controls the path of the rope 3 through the frame 8, but also avoids friction between the rope 3 and the inside of the frame 8, thus preventing damage.

[0036] In one illustrative embodiment, the steel pipe 6 is provided with a turning mechanism 4, which is used to turn the rope 3. The rope 3 needs to be turned when it enters the steel pipe 6 from the second end of the support 2. Without the turning mechanism 4, the friction and wear between the rope 3 and the steel pipe 6 will increase, and the rope 3 will easily break after long-term use.

[0037] In one illustrative embodiment, the steering mechanism 4 includes a fixed pulley 41 and a direction adjuster 42. The fixed pulley 41 is mounted on the direction adjuster 42, which is mounted at both ends of the steel pipe 6. The fixed pulley 41 is used to turn the rope 3, and the direction adjuster 42 is used to adjust the direction of the fixed pulley 41 according to the direction of the rope 3.

[0038] The fixed pulley 41 has a smooth circumferential surface. Through sliding contact with the circumferential surface of the fixed pulley 41, the rope 3 can be easily guided from the second end of the support 2 to the direction of entering the steel pipe 6. The fixed pulley 41 not only changes the direction of the rope 3 but also provides support and guidance, ensuring that the rope 3 maintains a stable path during operation and preventing it from deviating from the predetermined trajectory. Simultaneously, using the fixed pulley 41 reduces friction and wear, thereby extending the service life of the rope 3 and the equipment.

[0039] As the direction of the rope 3 to the second end of the support 2 changes continuously during the lifting process of the box 7, the direction adjuster 42 needs to adjust the direction of the fixed pulley 41 according to the direction of the rope 3, so as to prevent the rope 3 from separating from the fixed pulley 41.

[0040] In one illustrative embodiment, the direction adjuster 42 is a sleeve that is hinged to the steel pipe 6.

[0041] The fixed pulley 41 is set on the edge of the sleeve, and the sleeve can rotate around the steel pipe 6 as an axis, so that the direction adjuster 42 can flexibly adjust its angle relative to the steel pipe 6, and then adjust the direction of the fixed pulley 41 according to the direction of the rope 3.

[0042] In one illustrative embodiment, a rope adjustment mechanism 5 is provided at the second end of the bracket 2. The rope adjustment mechanism 5 is used to adjust the length of the rope 3. The rope adjustment mechanism 5 can tighten, loosen, extend, or shorten the rope 3, which facilitates the adjustment of the rope tension. At the same time, the rope adjustment mechanism 5 includes a locking structure for fixing the rope 3 after it has been adjusted to the required length. The rope adjustment mechanism 5 can also easily untie the rope 3 when needed for further adjustment or maintenance.

[0043] In one illustrative embodiment, the rope adjustment mechanism 5 is a winch. The winch typically includes a rotatable drum for winding or unwinding the rope 3. When the drum rotates forward, the rope 3 is wound around the drum, or when the drum rotates in the reverse direction, the rope 3 is unwound, allowing the winch to adjust the length and tension of the rope 3 in a very precise manner.

[0044] In one illustrative embodiment, the support 2 has a topological notch 21. The topological notch 21 is formed by removing part of the material from the support 2 through topology optimization, while meeting the mechanical requirements of the support 2. This minimizes the amount of material used and achieves a lightweight design for the support 2. Reducing the weight of the support 2 reduces the load on the rope 3, thereby extending the service life of the rope 3. The lightweight support 2 is also easier to move and install, reducing transportation and installation costs.
