Description

Technical Field

[0001] The present invention relates to the field of material handling equipment, in particular to a conveying equipment for traffic engineering construction. Background Art

[0002] The telescopic U-shaped conveyor is a highly efficient and flexible material conveying equipment. It mainly consists of a U-shaped trough, a telescopic mechanism, a conveyor chain or belt, a drive device and a supporting structure. The drive device drives the conveyor chain or belt to move in the U-shaped trough to convey materials. Its telescopic mechanism can adjust the length of the conveyor according to actual needs. It is widely used in port logistics, mining, construction and warehousing logistics. It has the advantages of high flexibility, high conveying efficiency, small space occupation and easy maintenance.

[0003] However, existing telescopic U-shaped conveyors have significant drop differences between the expansion joints during operation. When materials pass through the drop, they can cause impacts, jams, and even accumulation, disrupting the conveying process. Furthermore, to overcome the energy loss caused by the drop, the conveyor consumes more power, resulting in significant energy waste.

[0004] The information disclosed in the background technology section of the present invention is only intended to deepen the understanding of the general background technology of the present invention, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art.

[0015] In one embodiment, the flip support structure includes a locking structure, which is used to release the flip block in the extended state to provide support for the conveyor belt, and to lock the flip block in the retracted state.

[0016] In one embodiment, the flip support structure includes a limiting structure, and the limiting structure is used to limit the flip angle of the flip block.

[0017] In one embodiment, the locking structure includes a magnetic adsorption component, which is used to cause the flip block to flip at a predetermined position during the extension and retraction process of the conveying equipment in the traffic engineering construction.

[0018] In one embodiment, the magnetic adsorption component is configured as a magnet block.

[0019] In one embodiment, the elastic reset mechanism includes a first elastic member, and the first elastic member is used to enable the flip block to overcome the magnetic force of the magnetic adsorption component when the conveying equipment of the traffic engineering construction is extended and retracted.

[0020] In one embodiment, the flip block is fixedly provided with a hinge structure, and the first elastic member drives the flip block to flip through the hinge structure.

[0021] In one embodiment, the hinge structure includes a rotating block and a fixed block, and the rotating block and the fixed block are in contact with each other at an inclined surface, so that the rotating block and the fixed block rotate relative to each other within a right angle range.

[0022] The beneficial effects of the present invention are:

[0042] Refer to the following Figures 1-11 The following describes the conveying equipment for traffic engineering construction provided by an embodiment of the present invention.

[0043] The conveying equipment for traffic engineering construction provided by the embodiment of the present invention is particularly suitable for telescopic conveyors, and is used for flexible transportation of materials such as sand, gravel, concrete, fillers, etc. in traffic engineering construction scenarios such as road construction, bridge construction, tunnel excavation, etc. Of course, it can also be used for material handling operations such as mining, port loading and unloading, logistics warehousing, etc. that require dynamic adjustment of the conveying distance.

[0044] like Figure 1-Figure 2 Specifically, the conveying equipment for traffic engineering construction includes a main housing, multi-stage support assemblies, and a conveyor belt 100. The main housing encloses a relatively isolated space from the external environment, within which most other components are located, protecting the components within the main housing and preventing mechanical parts from causing harm to the user. The multi-stage support assemblies are slidably connected in sequence, allowing for extension and retraction. The conveyor belt 100 is continuously wound between the multi-stage support assemblies, extending and retracting in tandem with the expansion and contraction of the multi-stage support assemblies.

[0045] The conveying equipment for traffic engineering construction has a contracted state and an extended state. When the multi-stage support assembly is offset by the minimum distance, that is, when the conveyor belt 100 is in the shortest effective displacement, the conveying equipment for traffic engineering construction is in a contracted state; when the multi-stage support assembly is offset, that is, when the effective displacement of the conveyor belt 100 increases, the conveying equipment for traffic engineering construction is in an extended state.

[0046] Existing conveying equipment used in transportation engineering projects creates a vertical drop at the expansion joint due to structural gaps. This causes impact and accumulation of falling materials. The discontinuous flow of the conveyor belt 100 increases frictional resistance between the material and the conveying surface of the conveyor belt 100, reducing conveying efficiency. Furthermore, additional energy is required to compensate for the kinetic energy loss caused by impact. The material repeatedly undergoes conversion between gravitational potential energy and kinetic energy, resulting in reduced energy utilization.

[0047] Based on this, the multi-level support assembly includes at least two levels of flip support structures with different heights, so as to ensure that the conveyor belt 100 has a smooth transition.

[0048] Specifically, in the retracted state, the flip support structure is located at an initial position between two adjacent support assemblies; in the extended state, the flip support structure moves to the supporting position to support the conveyor belt 100 .

[0049] Since the multi-stage support assembly is located in different planes, the flip support structure of the multi-stage support assembly compensates for the height difference between the multi-stage support assembly and the conveyor belt 100 through different heights. Therefore, in the extended state, when the flip support structure supports the conveyor belt 100, the conveyor belt 100 has a smooth transition without height difference across the telescopic joint area.

[0050] The multi-level support assembly includes at least adjacent first-level support assembly 200 and second-level support assembly 300. The second-level support assembly 300 is provided with a flip support structure. The first-level support assembly 200 includes an elastic reset mechanism, which drives the flip support structure to move to the support position when in the extended state.

[0051] Specifically, the first-stage support assembly 200 is located above the second-stage support assembly 300. When the multi-stage support assembly is extended, the first-stage support assembly 200 and the second-stage support assembly 300 move relative to each other, and the flip support structure on the second-stage support assembly 300 gradually moves away from the first-stage support assembly 200. The elastic reset mechanism causes the flip support structure to move to the supporting position to support the conveyor belt 100. When the multi-stage support assembly is retracted, the flip support structure on the second-stage support assembly 300 is constrained by the first-stage support assembly 200 and moves in the same direction, lowering its own height.

[0052] Thus, the use of tilting support structures at different heights effectively eliminates sudden height changes at the joints of the conveyor belt 100, significantly improving the smoothness of material transportation and the energy efficiency of equipment operation. The elastic reset mechanism eliminates the need for external energy input during the tilting support structure's tilting process, reducing the system energy consumption of the conveyor equipment.

[0053] In one embodiment, Figure 3-Figure 5 As shown, the flip support structure includes a flip block 310, which is designed to continue supporting the conveyor belt 100 after rotating to a supporting position. In traditional conveying equipment, vertical support rods, due to their inherent structural characteristics, have poor resistance to lateral forces when dealing with the lateral torque generated by the conveyor's telescopic movement, which can easily lead to shaking and deflection, thereby affecting the smooth operation of the conveyor belt 100. To address this, the flip block 310 includes an inclined section and a vertical section, allowing the flip block 310 and the conveyor belt 100 to form a stable structure.

[0054] Specifically, the flip block 310 includes an inclined section and a vertical section. An end of the inclined section away from the vertical section is lower than the vertical section in the vertical direction. When in the extended state, the flip block 310 forms a stable support for the conveyor belt 100.

[0055] When the conveyor belt 100 is in operation, gravity is generated, and the telescopic movement of the conveying equipment also generates lateral torque. Because the inclined section of the flip block 310 forms a certain angle with the conveyor belt 100, the gravity and lateral torque from the conveyor belt 100 can be decomposed into a pressure component along the inclined section and a force component perpendicular to the inclined section. The vertical section primarily bears the vertical gravity of the conveyor belt 100. This greatly improves the stability of the flip block 310, enabling it to provide continuous and reliable support for the conveyor belt 100.

[0056] When the conveying device is in the contracted state, the turning block 310 is in the initial position. At this time, the conveyor belt 100 runs smoothly under the action of the first-level support assembly 200.

[0057] When the conveying device performs telescopic movement, the first-stage support assembly 200 and the second-stage support assembly 300 move relative to each other, causing the flip block 310 to start rotating.

[0058] When the conveying device is in the extended state, the flip block 310 rotates to the supporting position. At this time, the flip block 310 and the conveyor belt 100 form a stable structure, providing stable support for the conveyor belt 100.

[0059] Therefore, by setting up a stable structure formed by the flip block 310 with an inclined section and a vertical section and the conveyor belt 100, the lateral torque generated by the telescopic movement can be effectively decomposed and resisted, ensuring that the conveyor belt 100 will not have problems such as shaking and offset during operation, thereby ensuring the continuity and smoothness of material transportation.

[0060] In one embodiment, Figure 3-Figure 5 As shown, in order to enable the flip block 310 to reach the supporting position, the second-level support assembly 300 includes a second fixed plate 320, and the flip block 310 and the second fixed plate 320 are rotatably connected by a second elastic member. The elastic force of the second elastic member always makes the flip block 310 move away from the second fixed plate 320 or has a tendency to move away from the second fixed plate 320.

[0061] Specifically, when the conveying device begins to extend, the flip block 310 gradually breaks away from the restriction of the first-stage support assembly 200. The elastic force of the second elastic member pushes the flip block 310 to rotate, so that the flip block 310 quickly rotates to the supporting position, thereby providing support for the conveyor belt 100.

[0062] When the conveying device is in the extended state, the second elastic member will continue to apply force to the flip block 310. When the conveying device is in the retracted state, the flip block 310 will return to its original position close to the first-stage support assembly 200 under the elastic force of the second elastic member.

[0063] Therefore, by providing the second elastic member, it is ensured that the flip block 310 can smoothly reach the supporting position and stably support the conveyor belt 100.

[0064] In one embodiment, in a traffic engineering construction scenario, the telescopic length of the conveying equipment needs to be flexibly adjusted according to the actual application scenario. As a result, when the conveying equipment completes the extension action, the flip block 310 may not fully reach the support position. If the flip block 310 is higher than the normal height of the conveyor belt 100, the surface of the conveyor belt 100 will be uneven, affecting the conveying effect and the stability of the equipment. Based on this, Figure 3-Figure 5 As shown, the flip support structure includes a locking structure.

[0065] The locking structure releases the flip block 310 when the conveying device is in an extended state, so that the flip block 310 can provide support for the conveyor belt 100; when the conveying device is in a retracted state, the flip block 310 is locked to restrict the flipping of the flip block 310.

[0066] When the conveying device begins to extend, the locking structure locks the flip block 310 so that the flip block 310 cannot move to the supporting position.

[0067] When the conveying device extends to the middle or late stage, the locking structure can instantly release the lock of the turning block 310. At this time, the turning block 310 can quickly turn to the supporting position to provide stable support for the conveyor belt 100.

[0068] When the conveying device completes the extension action, the flip block 310 at the joint of the conveyor belt 100 is locked by the locking structure, and remains in a state of not flipping and not contacting the conveyor belt 100. Therefore, there will be no height difference caused by the protrusion of the flip block 310 at the joint of the conveyor belt 100.

[0069] Thus, by providing a locking structure, the conveyor equipment can precisely control the deflection timing of the flip block 310 during extension. This effectively prevents incomplete flipping of the flip block 310 at the joint of the conveyor belt 100 and avoids unevenness of the conveyor belt 100 caused by inconsistent heights of the flip block 310. This ensures a consistent support height of the flip block 310 in the second-stage support assembly 300, allowing the conveyor belt 100 to achieve a smooth transition during extension and retraction.

[0070] In one embodiment, Figure 3-Figure 5 As shown, the flip support structure includes a limiting structure, which is used to accurately limit the flip angle of the flip block 310. If the flip angle of the flip block 310 is too large, it will adversely affect the smooth operation of the conveyor belt 100, so a limiting structure is set on the second fixed plate 320.

[0071] Specifically, when the flip block 310 flips to the support position, the limiting structure blocks the flip block 310, preventing it from further flipping. The flip block 310 can stably remain in the support position, continuously providing reliable support for the conveyor belt 100 and ensuring that the conveyor belt 100 remains stable during the conveying process.

[0072] It is understood that the flip block 310 can also be flipped to a predetermined position by changing its shape and structure. For example, an extension plate can be extended from the end of the flip block 310 that contacts the second support plate. When the flip block 310 is in the supporting position, the extension plate will closely contact the second fixed plate 320, thereby acting like a position-limiting structure, stabilizing the flip block 310 in the desired supporting position.

[0073] Therefore, by providing the limiting structure, the problem of the conveyor belt 100 being unstable due to excessive turning of the turning block 310 is effectively prevented.

[0074] In one embodiment, Figure 3-Figure 5 As shown, the locking structure includes a magnetic adsorption component 330, which provides a temporary fixing force for the flip block 310 during the extension and retraction process of the conveying device, ensuring that the flip block 310 is flipped at a preset position.

[0075] The elastic reset mechanism includes a first elastic member 210 . When the conveying device performs an extension action, the first elastic member 210 can enable the flip block 310 to overcome the magnetic force of the magnetic adsorption component 330 .

[0076] Specifically, a magnet block 331 is provided on one side of the flip block 310, and the flip block 310 is made of magnetic material to achieve a magnetic adsorption effect. The first-level support assembly 200 is composed of a first fixed plate 220, a fixed component 230 and a movable component 240. Among them, the fixed component 230 is fixedly mounted on the first fixed plate 220, and the movable component 240 is slidably connected to the first fixed plate 220 and abuts against the flip block 310. One end of the first elastic member 210 is fixedly connected to the fixed component 230, and the other end of the first elastic member 210 is fixedly connected to the movable component 240. The elastic force of the first elastic member 210 always makes the fixed component 230 and the movable component 240 approach each other or have a tendency to approach each other.

[0077] During the initial extension of the conveying device, the flip block 310 is tightly attached to the magnet block 331 due to the adsorption effect of the magnet block 331. As the conveying device extends, the distance between the first-stage support assembly 200 and the second-stage support assembly 300 gradually increases, causing the first elastic member 210 to be continuously stretched. As the first elastic member 210 stretches, the pulling force exerted by the movable member 240 on the flip block 310 also gradually increases. When the pulling force increases to a level sufficient to overcome the magnetic force exerted by the magnet block 331 on the flip block 310, the flip block 310 instantly separates from the magnet block 331 and quickly flips to the supporting position. Once at the supporting position, the flip block 310 begins to support the conveyor belt 100, ensuring its stable operation. Under the elastic force of the first elastic member 210, the movable member 240 moves toward the fixed member 230 until it reaches the edge of the first fixed plate 220, and then prepares to perform the same flipping operation on the next adjacent flip block 310.

[0078] When the conveying device is retracted, under the restraining effect of the first-stage support assembly 200, the flip block 310 will deflect toward the direction of the magnet block 331. The flip block 310 is again tightly attached to the magnet block 331 and returns to the initial adsorption state.

[0079] Therefore, by setting up the magnetic adsorption component 330 and the first elastic member 210, the automatic flipping of the flip block 310 is achieved by utilizing the relative movement of the first-level support component 200 and the second-level support component 300, making the telescopic process of the conveying equipment automated and intelligent.

[0080] The temporary fixing force provided by the magnetic adsorption component 330 ensures that the flip block 310 flips at the right time, prevents the height difference of the conveyor belt 100, and improves the stability of the conveying equipment operation.

[0081] The first elastic member 210 makes the turning action of the turning block 310 faster and more reliable, can timely support the conveyor belt 100, and enhances the conveying efficiency and reliability of the conveying equipment.

[0082] In other embodiments that do not use the first elastic member 210, an electromagnetic structure may be used. The electromagnetic structure control system can accurately control the turning timing of the turning block 310 to meet different engineering requirements.

[0083] In one embodiment, Figure 3-Figure 11 As shown, in order to achieve rapid separation of the moving component 240 from the flip block 310 , a hinge structure 340 is fixedly provided on the flip block 310 .

[0084] The hinge structure 340 includes a rotating block 341 and a fixed block 342. The rotating block 341 and the fixed block 342 are in contact with each other at an angle, allowing them to rotate relative to each other only within a right angle. A third elastic member is positioned between the rotating block 341 and the fixed block 342 to constantly force the rotating block 341 and the fixed block 342 away from each other, or to create a tendency for them to move away from each other. The fixed block 342 is fixedly mounted to the vertical section of the flip block 310.

[0085] When the conveying device is in the contracted state, the turning block 310 is in the initial position. At this time, the rotating block 341 is perpendicular to the fixed block 342, and the rotating block 341 is in close contact with the moving component 240.

[0086] When the conveying device begins to extend, the relative rotation angle between the rotating block 341 and the fixed block 342 is limited and cannot be further increased. The rotating block 341 drives the movable part 240 to gradually move away from the fixed part 230, the first elastic part 210 will continue to be stretched, and the elastic potential energy stored in the first elastic part 210 will continue to increase. As the force of the first elastic part 210 on the movable part 240 gradually increases, the force of the movable part 240 on the rotating block 341 also increases accordingly. When this force reaches a certain level, it will prompt the flipping block 310 to start flipping. After the flipping block 310 flips, the position of the rotating block 341 changes, so that the rotating block 341 is no longer in contact with the movable part 240, thereby achieving rapid separation of the movable part 240 and the flipping block 310.

[0087] When the conveying device performs a contraction action, the moving component 240 applies a force to the rotating block 341, causing the rotating block 341 to rotate toward the fixed block 342, and the flip block 310 smoothly rotates to the initial position.

[0088] Thus, by providing the hinge structure 340, the movable member 240 and the flip block 310 can be quickly separated, effectively reducing mechanical interference during the operation of the conveying device, improving operational efficiency and flexibility, ensuring smooth switching between the retraction and extension of the conveying device, and enhancing the overall stability and reliability of the conveying device.

[0089] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention.
