Description

Technical Field

[0001] This invention relates to the field of loading and unloading equipment technology, and in particular to a novel boom structure and belt conveyor design for a telescopic boom ship loader. Background Technology

[0002] Telescopic boom ship loaders are the core equipment for loading and unloading operations at bulk cargo terminals. The telescopic stroke of the boom and the stability of the belt conveyor determine the coverage and operating efficiency of the loading operation. At present, the telescopic boom structures of ship loaders in China are mainly divided into two categories: mobile trolley type and internal and external boom type.

[0003] The mobile trolley type uses tracks laid on the outer boom, paired with a roller trolley longer than its telescopic stroke, and relies on wire rope traction or gear and rack transmission to achieve telescopic movement. Its telescopic stroke is directly limited by the length of the outer boom, resulting in a limited operating coverage area. The inner and outer boom type uses an outer boom connected to an inner boom, and completes the telescopic movement through rack and rack transmission. The telescopic distance is also limited by the length of the inner boom itself, making it difficult to expand the effective loading coverage area. The telescopic stroke of both structures is limited by the size of the boom or trolley itself, making it difficult to break through the original structural limitations to achieve a larger range of loading operations.

[0004] Meanwhile, traditional ship loaders mostly adopt a double-layer overlapping belt conveyor layout, with the layered arrangement of idlers creating a significant difference in belt height. During material transport, the belt is prone to deviation, affecting the stability of the transport. Furthermore, during bulk material transport, residual materials easily adhere to the belt surface. Conventional cleaning methods require additional power units, which complicates the structure and increases equipment energy consumption. Existing structures cannot simultaneously meet the requirements of belt deviation prevention and self-cleaning while extending the telescopic stroke, thus restricting the overall operating efficiency of ship loading operations. Summary of the Invention

[0005] Given the existing technical problems such as the telescopic stroke being constrained by the size of the boom or trolley itself, the double-layer belt layout being prone to deviation, and the need for an additional power unit for belt cleaning, a new type of belt conveyor for a telescopic boom ship loader is proposed.

[0006] Its purpose is to expand the effective ship loading coverage, eliminate height differences by adopting a single-layer belt layout, reduce the risk of material conveying deviation, and at the same time achieve self-driving material cleaning without power by relying on the friction of belt operation, thus simplifying the structure.

[0007] The technical solution of the present invention is a new type of belt conveyor for a telescopic boom ship loader, including a frame, a fixed boom rotatably disposed on the outer wall of the frame, a transmission belt rollingly disposed on the inner side wall of the fixed boom, a moving trolley fixedly disposed on the outer wall of the transmission belt, a conveyor belt rollingly disposed on the inner wall of the moving trolley, a fixed frame fixedly disposed on the outer wall of the frame, a limiting shaft fixedly disposed on the outer wall of the fixed frame, a movable frame slidably disposed on the inner wall of the frame, a connecting component fixedly disposed on the outer wall of the movable frame, a fixed component fixedly disposed on the inner wall of the connecting component, and a rotating component rotatably disposed on the outer wall of the connecting component. The outer wall of the conveyor belt is rotatably connected to the outer wall of the limiting shaft.

[0008] The connecting assembly includes a fixed plate fixedly disposed on the outer wall of the movable frame, a fixed ring fixedly disposed on the outer wall of the fixed plate, a positioning ring fixedly disposed on the inner wall of the fixed ring, and a rotating ring rotatably disposed on the outer wall of the fixed ring.

[0009] The fixing assembly includes a fixing tube fixedly disposed on the outer wall of the fixing ring at one end away from the rotating ring, a positioning component fixedly disposed on the inner wall of the fixing tube, a rotating rod rotatably disposed on the inner wall of the fixing tube, a rotating rod pushing component fixedly disposed on the rotating rod, and a connecting ring fixedly disposed on the outer wall of the rotating rod, wherein the outer wall of the connecting ring is fixedly connected to the outer wall of the rotating ring.

[0010] The positioning component includes a connecting pipe fixedly disposed on the inner wall of the fixed pipe, a limiting ring fixedly disposed on the inner side wall of the connecting pipe, a compression spring fixedly disposed on the top of the limiting ring, a sliding structure fixedly disposed on the top of the compression spring, and a squeezing structure slidably disposed on the inner wall of the sliding structure.

[0011] Furthermore, the sliding structure includes an extrusion column slidably disposed on the inner wall of the connecting pipe, a movable groove formed on the outer wall of the extrusion column, and a connecting groove formed on the inner wall of the extrusion column.

[0012] Furthermore, the extrusion structure includes a sliding rod slidably disposed on the inner wall of the extrusion column, a connecting shaft fixedly disposed on the top of the sliding rod, a spring sheet fixedly disposed on the outer wall of the connecting shaft, and a pressure column fixedly disposed on the top of the connecting shaft.

[0013] Furthermore, the outer wall of the spring is fixedly connected to the inner wall of the extrusion column through a connecting groove, and the outer wall of the pressure-bearing column is slidably connected to the inner wall of the extrusion column.

[0014] Furthermore, the pushing component includes a triangular block fixedly disposed on the outer wall of the rotating rod, a connecting hole extending through the inner wall of the triangular block, an extrusion slope formed on the outer wall of the tip of the triangular block, and an inwardly concave slope formed on the outer wall of the triangular block.

[0015] Furthermore, the rotating assembly includes a rotating tube rotatably disposed on the outer wall of the fixed ring, a mounting hole opened on the outer wall of the rotating tube, and a protruding component fixedly disposed on the inner wall of the rotating tube through the mounting hole.

[0016] Furthermore, the protruding component includes a fixing block fixedly disposed on the inner wall of the rotating tube, a clearance groove opened on the outer wall of the fixing block, a push-out structure slidably disposed on the inner wall of the fixing block, and an elastic rope fixedly disposed on the inner wall of the push-out fixing block, wherein the fixing block is elastic.

[0017] Furthermore, the ejection structure includes an ejection block fixedly disposed on the outer wall of the elastic rope, an inner groove formed on the bottom outer wall of the ejection block, a connecting post fixedly disposed on the top of the ejection block, and a pressure plate fixedly disposed on the top of the connecting post.

[0018] Another objective of this invention is to provide a novel boom structure for a telescopic ship loader, the purpose of which is to ensure the stable movement of the ship loader's moving trolley.

[0019] The system includes a fixed boom mounted on the outer wall of the frame. The fixed boom comprises a closed hollow frame, several inclined reinforcing rods fixed to the inner wall of the closed hollow frame, and the inclined reinforcing rods are symmetrically arranged on the inner wall of the fixed boom frame. A round rod is rotatably mounted on the side wall of the closed hollow frame. The fixed boom forms a triangular support structure on both sides through the intersecting arrangement of the inclined reinforcing rods. Together with the frame and the conveyor belt, it forms an integral ship loader boom load-bearing structure. The frame of the fixed boom is hollow inside, forming a track space for the reciprocating movement of the transmission belt and the moving trolley.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. By adopting a single-layer belt conveyor layout and optimizing the idler spacing, the belt height difference is eliminated, reducing material conveying deviation. The tension span is adjusted by the movable frame, breaking through the stroke limitation of the traditional structure and expanding the effective working range of the ship loader.

[0022] 2. The material cleaning mechanism is driven by the friction of the belt. The negative pressure pull generates high-frequency vibration to shake off the material adhering to the belt surface, avoiding material residue. The structure is simple and does not require an additional power source.

[0023] 3. Multiple sets of staggered triangular blocks trigger the material clearing points one by one, realizing the overall material clearing of the tension section of the conveyor belt. The sides of the triangular blocks are provided with concave slopes to provide avoidance space for structural rebound and effectively avoid reset jamming.

[0024] 4. The telescopic trolley is controlled by a transmission belt, which avoids the use of gears and racks, reducing its weight and size. This leads to a reduction in the weight of the entire machine and the outer boom, which can reduce the pressure on the dock legs and infrastructure costs. At the same time, it reduces the power of the luffing mechanism and saves on operating power consumption. Attached Figure Description

Detailed Implementation

[0038] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0039] Example 1, referring to Figure 1 - Figure 7 This first embodiment of the invention provides a novel belt conveyor for a telescopic boom ship loader, comprising a frame 1, a fixed boom 2 rotatably connected to the outer wall of the frame 1, a transmission belt 3 rollingly connected to the inner side wall of the fixed boom 2, a moving trolley fixedly connected to the outer wall of the transmission belt 3, a conveyor belt rollingly connected to the inner wall of the moving trolley, a fixed frame 4 fixedly connected to the outer wall of the frame 1, a limiting shaft 5 fixedly connected to the outer wall of the fixed frame 4, a movable frame 6 slidably connected to the inner wall of the frame 1, a connecting assembly 7 fixedly connected to the outer wall of the movable frame 6, a fixed assembly 8 fixedly connected to the inner wall of the connecting assembly 7, and a rotating assembly 9 rotatably connected to the outer wall of the connecting assembly 7. The outer wall of the conveyor belt is rollingly connected to the outer wall of the limiting shaft 5. The connecting assembly 7 includes a fixed plate 71 fixedly connected to the outer wall of the movable frame 6, a fixed ring 72 fixedly connected to the outer wall of the fixed plate 71, a positioning ring 73 fixedly connected to the inner wall of the fixed ring 72, and a rotating ring 74 rotatably connected to the outer wall of the fixed ring 72.

[0040] The fixing component 8 includes a fixing tube 81 fixedly connected to the outer wall of the fixing ring 72 at the end away from the rotating ring 74, a positioning component 82 fixedly connected to the inner wall of the fixing tube 81, a rotating rod 83 rotatably connected to the inner wall of the fixing tube 81, a pushing component 84 fixedly connected to the rotating rod 83, and a connecting ring 85 fixedly connected to the outer wall of the rotating rod 83, with the outer wall of the connecting ring 85 fixedly connected to the outer wall of the rotating ring 74; the positioning component 82 includes a connecting tube 821 fixedly connected to the inner wall of the fixing tube 81, a limiting ring 822 fixedly connected to the inner side wall of the connecting tube 821, a compression spring 823 fixedly connected to the top of the limiting ring 822, a sliding structure 824 fixedly connected to the top of the compression spring 823, and a pressing structure 825 slidably connected to the inner wall of the sliding structure 824.

[0041] Specifically, when this boom structure and belt conveyor are in operation, the frame 1 serves as the overall load-bearing foundation, the fixed boom 2 is fixed to the outer wall of the frame 1, the transmission belt 3 is tumblingly connected inside the fixed boom 2, driving the moving trolley to move along the boom track, the movable frame 6 is slidably connected to the inner wall of the frame 1, the fixed frame 4 is tumblingly engaged with the conveyor belt through the limiting shaft 5, and the connecting component 7, the fixed component 8, and the rotating component 9 are integrated at the movable frame 6, together forming the tensioning and cleaning mechanism of the single-layer belt conveyor. Compared with the shortcomings of traditional ship loaders whose telescopic stroke is limited by the length of the boom and trolley, this structure adopts a single-layer belt conveyor layout, optimizes the idler roller spacing to replace the traditional double-layer overlapping structure, eliminates the belt height difference, reduces the problem of material conveying deviation, and adjusts the tension span by telescopically extending the movable frame 6 to improve the effective coverage range of the ship loader. When the boom is extended or retracted, the movable frame 6 slides along the inner wall of the frame 1, changing the distance between the fixed frame 4 and the connecting component 7, and adjusting the distance between the limit shaft 5 and the rotating tube 91 of the rotating component 9. When the movable frame 6 extends outward, the distance between the two decreases, and the tensioning area of ​​the conveyor belt shrinks synchronously, allowing more belt allowance to adapt to large-stroke operations. When the movable frame 6 retracts inward, the tensioning area shrinks accordingly to adapt to the retracted state. The fixed plate 71 of the connecting component 7 is fixed to the outer wall of the movable frame 6. The fixed ring 72 and the positioning ring 73 form a slewing support base. The rotating ring 74 rotates circumferentially along the fixed ring 72, providing stable support for the rotating tube 91.

[0042] Reference Figure 1 - Figure 8 The sliding structure 824 includes an extrusion column 8241 slidably connected to the inner wall of the connecting tube 821, an active groove 8242 formed on the outer wall of the extrusion column 8241, and a connecting groove 8243 formed on the inner wall of the extrusion column 8241. The extrusion structure 825 includes a sliding rod 8251 slidably connected to the inner wall of the extrusion column 8241, a connecting shaft 8252 fixedly connected to the top of the sliding rod 8251, a spring piece 8253 fixedly connected to the outer wall of the connecting shaft 8252, and a pressure-bearing column 8254 fixedly connected to the top of the connecting shaft 8252. The outer wall of the spring piece 8253 is fixedly connected to the inner wall of the extrusion column 8241 through the connecting groove 8243, and the outer wall of the pressure-bearing column 8254 is slidably connected to the inner wall of the extrusion column 8241.

[0043] Specifically, during material conveying, the conveyor belt circulates along the limiting shaft 5 and the rotating tube 91. The working surface carrying the material faces outward, and the non-working surface is in contact with the outer wall of the rotating tube 91. The rotating tube 91 is driven to rotate synchronously around the fixed ring 72 by friction. The rotating tube 91 drives the rotating ring 74 to rotate. The rotating ring 74 is driven by the connecting ring 85 of the fixed component 8 to drive the rotating rod 83 to rotate around its own axis. When the rotating rod 83 drives the triangular block 841 to rotate, the extrusion slope 843 at its tip first contacts the extrusion structure 825 inside the positioning component 82. After being extruded, the pressure column 8254 drives the sliding rod 8251 to move down along the inner wall of the extrusion column 8241 of the sliding structure 824 through the connecting shaft 8252. The connecting groove 8243 on the inner wall of the extrusion column 8241 is fitted with the end of the fixed spring 8253. The spring 8253 is compressed and stores energy as it moves down. The movable groove 8242 provides sliding space for the sliding rod 8251. The movable groove 8242 and the inner cavity of the fixed tube 81 together form the receiving cavity of the compression spring 823. As the triangular block 841 continues to rotate, the extrusion slope 843 pushes the extrusion column 8241 down along the inner wall of the connecting tube 821 as a whole. The compression spring 823 above the limiting ring 822 is compressed. The sliding rod 8251 extends out from the bottom of the fixed tube 81 first and aligns with the mounting hole 92 at the corresponding position.

[0044] Reference Figure 1 - Figure 9 The pushing component 84 includes a triangular block 841 fixedly connected to the outer wall of the rotating rod 83, a connecting hole 842 through the inner wall of the triangular block 841, a pressing slope 843 on the outer wall of the tip of the triangular block 841, and a concave slope 844 on the outer wall of the triangular block 841.

[0045] Specifically, the triangular block 841 of the pushing component 84 is sleeved on the outer wall of the rotating rod 83 through the connecting hole 842. Multiple sets of triangular blocks 841 are arranged axially and staggered in phase, respectively corresponding to the mounting holes 92 at different angles on the rotating tube 91, triggering the positioning component 82 point by point. The concave inclined surface 844 on the side of the triangular block 841 can provide clearance space when the structure rebounds, avoiding reset jamming. The extrusion pressure can be smoothly dissipated through the concave inclined surface 844, ensuring smooth and stable structure rebound reset.

[0046] Example 2, refer to Figure 1 - Figure 10 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the rotating component 9 includes a rotating tube 91 rotatably connected to the outer wall of the fixed ring 72, a mounting hole 92 opened on the outer wall of the rotating tube 91, and a protruding part 93 fixedly connected to the inner wall of the rotating tube 91 through the mounting hole 92.

[0047] Specifically, when the mounting hole 92 rotates with the rotating tube 91 to directly below the fixed tube 81, the sliding rod 8251 passes into the mounting hole 92, precisely triggering the protruding part 93 inside the rotating tube 91, thereby realizing the automated fixed-point triggering of the material cleaning process.

[0048] Reference Figure 1 - Figure 10 The protruding component 93 includes a fixing block 931 fixedly connected to the inner wall of the rotating tube 91, a relief groove 933 opened on the outer wall of the fixing block 931, a push-out structure 932 slidably connected to the inner wall of the fixing block 931, and an elastic rope 934 fixedly connected to the inner wall of the push-out fixing block 931. The fixing block 931 is elastic.

[0049] Specifically, after the sliding rod 8251 passes through the mounting hole 92, it squeezes the pressure plate 9331 of the protruding part 93. The elastic rope 934 can stretch and store energy during the sliding of the ejection structure 932. The elastic fixing block 931, together with the clearance groove 933, provides sufficient space for the sliding displacement of the ejection structure 932.

[0050] Reference Figure 1 - Figure 11 The ejection structure 932 includes an ejection block 9323 fixedly connected to the outer wall of the elastic rope 934, an inner groove 9324 formed on the bottom outer wall of the ejection block 9323, a connecting post 9322 fixedly connected to the top of the ejection block 9323, and a pressure plate 9331 fixedly connected to the top of the connecting post 9322.

[0051] Specifically, the pressure plate 9331 drives the ejection block 9323 of the ejection structure 932 to slide along the clearance groove 933 of the fixed block 931 towards the conveyor belt via the connecting column 9322. The elastic rope 934 stretches and stores energy, and the inner groove 9324 at the bottom of the ejection block 9323 forms a negative pressure space close to the conveyor belt. After the squeezing pressure dissipates, the compression spring 823 and the spring piece 8253 rebound and reset, driving the squeezing column 8241 and the sliding rod 8251 to retract. The ejection block 9323 quickly retracts under the tension of the elastic rope 934, generating high-frequency vibration by pulling the conveyor belt through negative pressure, shaking off the material adhering to the belt surface. Multiple sets of staggered triangular blocks 841 correspond to multiple sets of mounting holes 92 and protruding parts 93, triggering multi-point vibration in sequence, covering the entire tension section. The overall structure relies on the friction of the belt for drive, requiring no additional power. While achieving large-stroke extension and reducing the probability of deviation, it simultaneously completes belt self-cleaning, improving the stability and conveying efficiency of the ship loader. The remaining structures are the same as those in Embodiment 1.

[0052] Based on embodiments 1-2, the working principle of this invention is as follows: When the boom structure and belt conveyor are in operation, the frame 1 serves as the overall load-bearing foundation, the fixed boom 2 is fixed to the outer wall of the frame 1, the transmission belt 3 is tumblingly connected inside the fixed boom 2, driving the moving trolley to move along the boom track, the movable frame 6 is slidably connected to the inner wall of the frame 1, the fixed frame 4 is tumblingly engaged with the conveyor belt through the limiting shaft 5, and the connecting component 7, the fixed component 8, and the rotating component 9 are integrated at the movable frame 6, together forming the tensioning and cleaning mechanism of the single-layer belt conveyor. Compared with the shortcomings of traditional ship loaders whose telescopic stroke is limited by the length of the boom and trolley, this structure adopts a single-layer belt conveyor layout, optimizes the idler roller spacing to replace the traditional double-layer overlapping structure, eliminates the belt height difference, reduces the problem of material conveying deviation, and improves the effective coverage range of the ship loader by adjusting the telescopic span of the movable frame 6.

[0053] When the boom is extended or retracted, the movable frame 6 slides along the inner wall of the frame 1, changing the distance between the fixed frame 4 and the connecting component 7, and adjusting the distance between the limit shaft 5 and the rotating tube 91 of the rotating component 9. When the movable frame 6 extends outward, the distance between the two decreases, and the tensioning area of ​​the conveyor belt shrinks synchronously, allowing more belt allowance to adapt to large-stroke operations. When the movable frame 6 retracts inward, the tensioning area shrinks accordingly to adapt to the retracted state. The fixed plate 71 of the connecting component 7 is fixed to the outer wall of the movable frame 6. The fixed ring 72 and the positioning ring 73 form a slewing support base. The rotating ring 74 rotates circumferentially along the fixed ring 72, providing stable support for the rotating tube 91.

[0054] During material conveying, the conveyor belt circulates along the limiting shaft 5 and the rotating tube 91. The working surface carrying the material faces outward, and the non-working surface is in contact with the outer wall of the rotating tube 91. The rotating tube 91 is driven to rotate synchronously around the fixed ring 72 by friction. The rotating tube 91 drives the rotating ring 74 to rotate. The rotating ring 74 is driven by the connecting ring 85 of the fixed component 8 to drive the rotating rod 83 to rotate around its own axis. The triangular block 841 of the pushing component 84 is sleeved on the outer wall of the rotating rod 83 through the connecting hole 842. Multiple sets of triangular blocks 841 are arranged axially and staggered in phase, respectively corresponding to the mounting holes 92 at different angles on the rotating tube 91, triggering the positioning component 82 point by point. The concave inclined surface 844 on the side of the triangular block 841 can provide clearance space when the structure rebounds, avoiding reset jamming.

[0055] When the rotating rod 83 drives the triangular block 841 to rotate, the extrusion slope 843 at its tip first contacts the extrusion structure 825 inside the positioning component 82. After being extruded, the pressure column 8254 drives the sliding rod 8251 to move down along the inner wall of the extrusion column 8241 of the sliding structure 824 through the connecting shaft 8252. The connecting groove 8243 on the inner wall of the extrusion column 8241 is fitted with the end of the fixed spring 8253. The spring 8253 is compressed and stores energy as it moves down. The movable groove 8242 provides sliding space for the sliding rod 8251. The movable groove 8242 and the inner cavity of the fixed tube 81 together form the receiving cavity of the compression spring 823. As the triangular block 841 continues to rotate, the extrusion slope 843 pushes the extrusion column 8241 down along the inner wall of the connecting tube 821 as a whole. The compression spring 823 above the limiting ring 822 is compressed. The sliding rod 8251 extends out from the bottom of the fixed tube 81 first and aligns with the mounting hole 92 at the corresponding position.

[0056] When the mounting hole 92 is rotated to be directly below the fixed tube 81, the sliding rod 8251 passes through the mounting hole 92, squeezing the pressure plate 9331 of the protruding part 93. Through the connecting column 9322, the pushing block 9323 of the pushing structure 932 slides along the clearance groove 933 of the fixed block 931 toward the conveyor belt. The elastic rope 934 stretches and stores energy. The inner groove 9324 at the bottom of the pushing block 9323 is close to the conveyor belt to form a negative pressure space. After the squeezing force is dissipated by the concave inclined surface 844, the compression spring 823 and the spring piece 8253 rebound and reset, driving the squeezing column 8241 and the sliding rod 8251 to retract. The pushing block 9323 retracts rapidly under the tension of the elastic rope 934. The negative pressure pulls the conveyor belt to generate high-frequency vibration, shaking off the material adhering to the belt surface.

[0057] Multiple sets of interlaced triangular blocks 841 correspond to multiple sets of mounting holes 92 and protruding parts 93, triggering multi-point vibrations in sequence, covering the entire tension section. The overall structure is driven by belt friction, requiring no additional power. While achieving large stroke extension and reducing the probability of deviation, it simultaneously completes belt self-cleaning, improving the stability and conveying efficiency of the ship loader.
