Description

Technical Field

[0001] This invention patent belongs to the technical field of engineering maintenance auxiliary equipment, specifically relating to a special hook assembly for relocating a movable conveyor. Background Technology

[0002] Relocating conveyors are commonly used in medium to large-sized open-pit mine conveyor rock discharge systems. They consist of head and tail drives, tensioning devices, conveyor rollers, a conveyor frame, relocating skid sleepers, and the track steel for the rock discharge machine's unloading trolley. The conveyor frame is a split-type frame, mounted on the relocating skid sleepers and connected as a whole by the track steel for the rock discharge machine's unloading trolley. In open-pit mine conveyor rock discharge systems, the relocation of the relocating conveyor creates new space for rock discharge operations. Therefore, the relocation of the relocating conveyor is a key technological step in the waste rock discharge process of open-pit mine conveyor systems. Currently, the relocation of conveyors is generally carried out using specialized relocation machines. These machines consist of a relocation traveling device and a hydraulic traction device. The hydraulic traction device is installed on the relocation traveling device. During the relocation process, the hydraulic traction device uses pulleys and rail clamps to hold the track steel of the unloading trolley of the rock dumping machine. After lifting it a certain distance off the ground, the relocation traveling device moves along the conveyor, dragging the conveyor in the relocation direction. The following problems mainly exist in its application in mining production: 1. The maximum distance that a dedicated relocation machine can tow a relocation conveyor in a single operation is 0.6m. The small single towing distance results in low relocation efficiency and a long relocation period for the relocation conveyor. 2. The special relocation machine is suitable for relocation on horizontal ground. It has high requirements for the flatness of the ground. When there are low and undulating ground, it is easy to cause the steel rail of the unloading trolley of the rock dumping machine to break. It cannot be used for relocation of the relocation conveyor on inclined surface. It has limitations in use and cannot adapt to the complex relocation operation surface of the relocation conveyor. 3. The dedicated relocation machine is only used when the relocation conveyor is moved. It is idle most of the time, and the frequency of production use is low, resulting in low asset utilization.

[0003] In view of the current state of production and use of dedicated relocation machines for moving conveyors, which suffer from problems such as low relocation efficiency, poor production applicability, and low asset utilization, this invention proposes a dedicated hook assembly for relocating moving conveyors. Summary of the Invention

[0004] To address the aforementioned problems, this invention aims to provide a dedicated hook assembly for relocating conveyors. This device can solve the problems of low relocation efficiency, poor production applicability, and low asset utilization in existing dedicated relocation machines for relocating conveyors.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: a special hook assembly for moving conveyors, wherein the front end of the hook assembly is welded to the bucket of the construction machinery, the hook assembly includes a U-shaped lug, a rail steel hook, a U-shaped ring A, a U-shaped ring B, and a double-buckled steel wire rope, the top end of the U-shaped lug is welded to the bucket of the construction machinery, the bottom end of the U-shaped lug is connected to the opening of the U-shaped ring A through a bolt-and-screw hole structure, the U-shaped ring A and U-shaped ring B are respectively fitted onto the rope buckles at the front and rear ends of the double-buckled steel wire rope, and the opening of the U-shaped ring B is connected to the top end of the rail steel hook through a bolt-and-screw hole structure.

[0006] Preferably, the construction machinery can be any one or any combination of 6 to 8 bulldozers, loaders or excavators, with each construction machinery arranged vertically to the transfer conveyor and the interval distance set to 5-10m.

[0007] Preferably, the U-shaped lug is made of steel plate and has a symmetrical triangular structure. The long side of the top is welded to the bucket of the construction machinery. The bottom center of the U-shaped lug has a hanging hole through which a bolt can pass.

[0008] Preferably, the length of the double-buckled wire rope is set to 1.2~1.5m. The loops at both ends of the double-buckled wire rope can be woven together as one piece or made by wire rope clips.

[0009] Preferably, the rail steel hook is provided with an opening that can laterally lock the movable conveyor track.

[0010] The present invention also provides an application of a special hook assembly for relocating a transfer conveyor in the relocation of the transfer conveyor.

[0011] This invention also provides a method for applying a special hook assembly for relocating a transfer conveyor during the relocation of the transfer conveyor, specifically including the following steps: S1. First, assemble the relocation hook assembly for the transfer conveyor. After assembly, weld the U-shaped lugs in the relocation hook assembly to the bottom of the bucket of the construction machinery. S2. During the relocation of the transfer conveyor, multiple engineering machines are used simultaneously to laterally embed and assemble the rail steel hooks in the relocation special hook assembly with the traveling rail steel of the rock discharge machine unloading trolley. S3. Next, the engineering machinery equipment lifts the bucket, pre-tightens and moves the special hook assembly, and checks and confirms that the track steel hook suspends the rock discharge machine unloading trolley travel track steel is securely fixed. S4. Then, the engineers simultaneously raised the buckets of all the engineering machinery to lift the conveyor's movable skid sleepers a certain distance off the ground and dragged the movable conveyor backward to move it to the designated location.

[0012] Preferably, the method for assembling the special hook assembly for the transfer conveyor in S1 includes the following steps: using a U-ring to connect the U-ring lug to one end of the double-buckled wire rope, and then using another U-ring to connect the track steel hook to the other end of the double-buckled wire rope, thus completing the assembly of the special hook assembly. When assembling the U-ring, the U-ring bolts should be tightened beforehand and then loosened by half a turn of the thread to facilitate the removal of the U-ring connection after use. The arc-shaped ends of both U-rings are located on one side of the double-buckled wire rope, and the bolt ends are respectively connected to the U-ring lug and the track steel hook to protect the double-buckled wire rope and prevent the U-rings from rotating and sliding.

[0013] The beneficial effects of this invention are: This invention, by adding a special hook assembly to the bucket of engineering machinery, enables multiple engineering machines to work simultaneously. The single towing distance is not limited by the equipment structure and can be adjusted according to operational needs, effectively improving the relocation efficiency of the transfer conveyor and shortening the relocation period. At the same time, the device is adaptable to relocation operations on low-lying and undulating ground as well as inclined surfaces, without being limited by the flatness of the working surface, making it more versatile and able to meet the relocation needs of transfer conveyors under complex working conditions. In addition, this device can be modified from bulldozers, loaders, or excavators commonly used in mining, without the need to purchase additional special relocation equipment. The equipment idle rate is low, which greatly improves asset utilization and reduces the overall cost of relocation operations. This component can be welded and installed on the bucket of mining machinery, enabling multiple machines to simultaneously tow a transfer conveyor, increasing the single towing distance and improving relocation efficiency. Using this dedicated hook assembly for transfer conveyor relocation allows for towing of the conveyor not only on horizontal surfaces but also on inclined surfaces, with reduced requirements for surface flatness, making it widely applicable to complex transfer conveyor relocation work surfaces. This dedicated hook assembly for transfer conveyor relocation has a simple structure, is easy to manufacture, and can be used for routine leveling and balancing of the conveyor foundation. After relocation, the hook assembly can be removed without affecting the normal production and operation of the machinery. Attached Figure Description

[0014] To more clearly illustrate the technical solutions of the embodiments of the present invention, the accompanying drawings used in the description of the embodiments will be briefly introduced below. Those skilled in the art can obtain other drawings based on these drawings without creative effort. Figure 1 This is the front view of the present invention; Figure 2 This is the left view of the present invention; Figure 3 This is a top view of the present invention; Figure 4 This is a real-world application illustration of the present invention; The attached diagram lists the components represented by each number as follows: 1.

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention. Example 1

[0016] like Figures 1 to 4 As shown, the existing technology in this embodiment has the following problems: the existing technology of the transfer conveyor has problems such as low transfer efficiency, poor production applicability and low asset utilization.

[0017] Therefore, the inventor provides a special hook assembly for the relocation of a transfer conveyor. The front end of the hook assembly is welded to the bucket of the construction machinery. The hook assembly includes a U-shaped lug, a rail steel hook, a U-shaped ring A, a U-shaped ring B, and a double-buckled steel wire rope. The top end of the U-shaped lug is welded to the bucket of the construction machinery. The bottom end of the U-shaped lug is connected to the opening of the U-shaped ring A through a bolt-and-screw hole structure. The U-shaped ring A and U-shaped ring B are respectively fitted onto the rope buckles at the front and rear ends of the double-buckled steel wire rope. The opening of the U-shaped ring B is connected to the top end of the rail steel hook through a bolt-and-screw hole structure.

[0018] As a preferred embodiment, the construction machinery can be any one or any combination of 6 to 8 bulldozers, loaders or excavators, with each construction machinery arranged vertically to the transfer conveyor and the interval distance set to 5-10m.

[0019] The principle and effect of adopting the above-mentioned further solution are as follows: by using multiple engineering equipment to move the equipment simultaneously, compared with the original dedicated relocation machine's single-trip towing distance of 0.6m, a single towing can complete the overall displacement of the entire conveyor section. The single-trip towing distance is not limited by the equipment structure, which can significantly shorten the relocation period and improve the efficiency of the relocation operation. At the same time, the modification operation can be carried out using bulldozers, loaders or excavators commonly used in mines, without the need to purchase additional dedicated relocation equipment, reducing the asset waste of long-term idle dedicated equipment and improving the utilization rate of equipment assets.

[0020] As a preferred embodiment, the U-shaped lug is made by cutting steel plate and has an overall symmetrical triangular structure. The top long side is welded to the bucket of the construction machinery, and the bottom center of the U-shaped lug has a hanging hole through which a bolt can pass.

[0021] The principle and effect of adopting the above-mentioned further solution are as follows: the symmetrical triangular structure can disperse the tensile force during the dragging process, improve the structural stability of the U-shaped lug, avoid stress concentration leading to cracking of the welded parts, and ensure the strength and service life of the overall structure.

[0022] In a preferred embodiment, the length of the double-buckled wire rope is set to 1.2~1.5m. The loops at both ends of the double-buckled wire rope can be integrally woven or made using wire rope clips.

[0023] The principle and effect of adopting the above-mentioned further solution are as follows: the steel wire rope within this length range can reserve enough lifting space to lift the entire conveyor off the ground to avoid jamming during movement, and the displacement during the towing process will not be too large due to the excessive length of the steel wire rope. This makes it convenient for each piece of engineering machinery to control the towing direction and lifting height synchronously, and adapt to different working conditions with different ground undulations.

[0024] In a preferred embodiment, the rail steel hook is provided with an opening that can laterally lock the track of the movable conveyor.

[0025] The principle and effect of the above-mentioned further solution are as follows: the transversely engaging opening structure can quickly complete the assembly and connection with the track steel of the rock discharge machine's unloading trolley; the hook bears the load evenly and will not cause structural damage to the track steel; at the same time, it can adapt to working grounds with different inclination angles, solving the limitation of the original dedicated relocation machine that can only operate on flat, level ground; it is suitable for complex undulating and sloping relocation working surfaces, improving the applicability of the device. This invention can complete the relocation of the relocation conveyor by adding hook components to existing mining engineering machinery equipment, greatly improving relocation efficiency, reducing asset waste caused by equipment idleness, and adapting to various complex working conditions. It solves many technical problems existing in the current dedicated relocation equipment and is suitable for widespread application in the relocation of relocation conveyors in open-pit mines.

[0026] The present invention also provides an application of a special hook assembly for relocating a transfer conveyor in the relocation of the transfer conveyor.

[0027] This invention also provides a method for applying a special hook assembly for relocating a transfer conveyor during the relocation of the transfer conveyor, specifically including the following steps: S1. First, assemble the relocation hook assembly for the transfer conveyor. After assembly, weld the U-shaped lugs in the relocation hook assembly to the bottom of the bucket of the construction machinery. S2. During the relocation of the transfer conveyor, multiple engineering machines are used simultaneously to laterally embed and assemble the rail steel hooks in the relocation special hook assembly with the traveling rail steel of the rock discharge machine unloading trolley. S3. Next, the engineering machinery equipment lifts the bucket, pre-tightens and moves the special hook assembly, and checks and confirms that the track steel hook suspends the rock discharge machine unloading trolley travel track steel is securely fixed. S4. Then, the engineers simultaneously raised the buckets of all the engineering machinery to lift the conveyor's movable skid sleepers a certain distance off the ground and dragged the movable conveyor backward to move it to the designated location.

[0028] As a preferred embodiment, the method for assembling the special hook assembly for the transfer conveyor in S1 specifically includes the following: using a U-shaped ring to connect the U-shaped ring lug to one end of the double-buckled steel wire rope, and then using another U-shaped ring to connect the track steel hook to the other end of the double-buckled steel wire rope, thus completing the assembly of the special hook assembly. When assembling the U-shaped ring, the U-shaped ring bolts should be tightened beforehand and then loosened by half a turn of the thread to facilitate the removal of the U-shaped ring connection after use. The arc-shaped ends of both U-shaped rings are located on one side of the double-buckled steel wire rope, and the bolt ends are respectively connected to the U-shaped ring lug and the track steel hook to protect the double-buckled steel wire rope and prevent the U-shaped rings from rotating and sliding. Example 2

[0029] Based on the above embodiments, the inventors have applied the above technical solutions in practice, such as... Figures 1 to 4 As shown, the components and their specific applications are as follows: 1) U-shaped hook: The U-shaped hook is made of steel plate with good wear resistance and high strength. The whole is in the shape of a symmetrical triangular structure with a U-shaped ring hanging hole in the middle. The size meets the assembly requirements of the U-shaped ring. It is welded and installed on the bucket of the engineering equipment or a suitable position, serving as the connection anchor point between the hook assembly and the engineering equipment. When the moving conveyor is moved, it bears a large tensile force, so the welding and assembly quality must be guaranteed. 2) U-shaped ring: This hook assembly includes two U-shaped rings of the same model. One serves as the connection between the double-buckle wire rope and the U-shaped lug, and the other serves as the connection between the double-buckle wire rope and the rail steel hook. Applicable models can be purchased on the market. The selection is determined by the size of the conveyor to be moved and the amount of force during the moving process. If the U-shaped ring deforms frequently during the moving process, it is necessary to select and replace it with a U-shaped ring that can withstand greater force. 3) Double-buckle steel wire rope: The double-buckle steel wire rope is the main force transmission component in this assembly. It is purchased and customized from the market. The length is generally 1.2-1.5m, which can be determined according to the engineering equipment and the installation location of the assembly. The loops at both ends can be made as one piece or made by steel wire rope clips. The type of steel wire rope used is determined according to the size of the conveyor to be moved and the amount of force during the moving process. At the same time, objects with the same function and properties can also be selected as substitutes. 4) Rail steel hook: The rail steel hook is the core component of this assembly. It is designed and manufactured with wear-resistant and high-strength steel plates. Its shape and size are fitted to the rail steel of the transfer conveyor. During the transfer process, it can firmly lock the rail steel of the transfer conveyor in the lateral direction, serving as a reliable force point for the engineering machinery to drag the transfer conveyor.

[0030] The assembly method for the special hook assembly for the relocation conveyor is as follows: use a U-ring to connect the U-shaped lug to one end of the double-buckled steel wire rope, and then use another U-ring to connect the track steel hook to the other end of the double-buckled steel wire rope. This completes the assembly of the special hook assembly. Special note: when assembling the U-ring, the U-ring bolts should be tightened beforehand and then loosened by half a turn of the thread to facilitate the removal of the U-ring connection after use. The arc-shaped ends of both U-rings are located on one side of the double-buckled steel wire rope, and the bolt ends are connected to the U-shaped lug and the track steel hook respectively, which can protect the double-buckled steel wire rope and prevent the U-rings from rotating and slipping.

[0031] The specific application method of this relocation hook assembly for the transfer conveyor is as follows: Before relocating the transfer conveyor, the U-shaped lugs of the assembled relocation hook assembly are welded and installed at a suitable height on the bucket of the engineering machinery equipment; during the relocation of the transfer conveyor, the rail steel hook of the relocation hook assembly is laterally embedded and fitted with the traveling rail steel of the rock dumping machine unloading trolley. The engineering machinery equipment raises the bucket to pre-tighten the relocation hook assembly, checks and confirms that the rail steel hook is securely fixed to the traveling rail steel of the rock dumping machine unloading trolley, and directs the engineering machinery equipment to raise the bucket again to lift the transfer-type skid sleeper of the conveyor a certain distance off the ground, and then drags the transfer conveyor backward to realize the relocation of the transfer conveyor to the designated position. According to the relocation construction organization design, multiple engineering machinery equipment can be used simultaneously to tow the relocation conveyor. The safety of the relocation operation and the difficulty of coordinating multiple engineering machinery equipment must be considered. Generally, it is most suitable for 6-8 engineering machinery equipment to operate at the same time. Each engineering machinery equipment should be arranged perpendicular to the relocation conveyor, with an interval distance of 5-10m. Each time the relocation conveyor is towed, the special hook assembly for relocation should be checked for integrity. If the assembly is deformed or damaged, it should be replaced in time. During the towing process, pay attention to the bending deformation of the rock discharge machine unloading trolley's traveling rail steel, and appropriately control the single towing distance to prevent excessive bending and breakage of the rock discharge machine unloading trolley's traveling rail steel.

[0032] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0033] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
