Description

Technical Field

[0001] This invention belongs to the field of stacker-reclaimer technology, and in particular relates to a stacker-reclaimer boom. Background Technology

[0002] Stacker-reclaimers belong to the field of large-scale high-end equipment remanufacturing and are widely used in industries such as ports, docks, steel, mining, metallurgy, thermal power, and material storage, as well as in engineering sites for the stacking, conveying, and equalization of bulk materials in industrial and mining enterprises. They can be used in conjunction with unloading (ship) machines, belt conveyors, and ship (vehicle) loaders to form a mechanized material storage and transportation system, or they can be used independently. They have advantages such as large stacking and unloading capacity, small material yard footprint, convenient loading and unloading, high degree of mechanization, and easy automatic control. When a stacker-reclaimer is working, the bulk material transported by a belt conveyor is unloaded onto a belt conveyor on the cantilever via a tail car, and then dumped from the front end of the cantilever to the stockyard. The rotation and pitching of the cantilever allow the stockpile to form a neat trapezoidal cross-section. Reclaiming is achieved through the rotation and pitching of the cantilever and the continuous rotation of the bucket wheel. The material is unloaded via a discharge plate onto a belt conveyor running in the opposite direction on the cantilever, and then discharged through a hopper below the center of the equipment to the stockyard belt conveyor for removal. The rotation and pitching of the cantilever allow the bucket wheel to completely remove material from the stockpile. Currently, most stacker-reclaimers use a single-piece boom structure, which is bulky and heavy, making transportation difficult and requiring large lifting equipment for on-site assembly, thus hindering operation. Therefore, it is necessary to improve the boom of existing stacker-reclaimers. Summary of the Invention

[0003] In view of this, the present invention aims to overcome the deficiencies in the prior art and proposes a stacker-reclaimer boom.

[0004] To achieve the above objectives, the technical solution created by this invention is implemented as follows:

[0005] A stacker-reclaimer boom includes a boom body comprising several segments, each segment being detachably connected. A head-end connection assembly is fixed to the segment at the head end of the boom body, and a tail-end connection assembly is fixed to the segment at the tail end of the boom body. The head-end connection assembly includes a base with an upwardly sloping overhang and an arc-shaped groove on the overhang. The tail-end connection assembly includes a tail seat with a connecting seat at its end. Both ends of the connecting seat extend outward from the tail seat, and an array of tail-end tie rods are provided between the connecting seat and the tail seat. Furthermore, an array of boom tie rods is provided between the segments at the head end and the segments at the tail end of the boom body. A reinforcing frame is provided inside the tail seat corresponding to the tail seat tie rod fixing seat, and each tail seat tie rod fixing seat is simultaneously connected to the reinforcing frame and the tail seat side plate.

[0006] Furthermore, each of the aforementioned components is provided with a component connecting flange at both ends, and the component connecting flanges between adjacent components are fixed together by bolts.

[0007] Furthermore, the base is provided with a base connecting flange at one end facing the split body, and the base connecting flange is fixed to the split body connecting flange at the head end of the main body by bolts.

[0008] Furthermore, the tailstock is provided with a tailstock connecting flange at the end facing the split body, and the tailstock connecting flange is fixed to the split body connecting flange at the tail end of the boom body by bolts.

[0009] Furthermore, two sets of boom tie rods are symmetrically arranged on the boom body. Two tie rod head fixing seats are symmetrically provided on the split at the front end of the boom body, and two tie rod tail fixing seats are symmetrically provided on the split at the rear end of the boom body. Both ends of each set of boom tie rods can be detachably connected to the tie rod head fixing seat and tie rod tail fixing seat on the same side.

[0010] Furthermore, each side of the tailstock is provided with two sets of tail end pull rods, and the angle between the two tail end pull rods on the same side of the tailstock is an acute angle.

[0011] Furthermore, each side of the tailstock is provided with two tailstock tie rod fixing seats, and the two tailstock tie rod fixing seats on the same side of the tailstock are in different positions; the connecting seat is symmetrically provided with connecting seat tie rod fixing seats at both ends, and one end of the two tail end tie rods on the same side of the tailstock is simultaneously installed on the connecting seat tie rod fixing seat, and the other end is respectively installed on tailstock tie rod fixing seats at different heights.

[0012] Furthermore, one end of each of the two tail rods on the same side of the tailstock can be detachably installed on the connecting seat rod fixing seat, and the other end can be detachably installed on tailstock rod fixing seats at different heights.

[0013] Compared with existing technologies, the present invention has the following advantages:

[0014] This invention features a rationally designed structure. Through a modular design, it can be manufactured in sections, reducing production difficulty. It can be assembled and installed on-site, cleverly solving the various inconveniences encountered during transportation due to its large size, making it more practical. Because the main structural components of the stacker-reclaimer's boom are primarily made of high-strength steel, the assembled frame structure has a stable internal cavity structure. Compared to the integral stacker-reclaimer booms of existing technologies, this invention effectively reduces the overall weight. The length and angle of the boom can be adjusted according to actual needs to meet different scales of stacking and reclaiming requirements. Attached Figure Description

[0027] The invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] A stacker-reclaimer boom, such as Figures 1 to 8 As shown, the boom body includes several segments 1, each segment being detachably connected. A head-end connection assembly 2 is fixed to the segment at the head end of the boom body, and a tail-end connection assembly 3 is fixed to the segment at the tail end of the boom body. The head-end connection assembly includes a base 4, which has an upwardly sloping cantilevered portion 5, and an arc-shaped groove 6 is provided on the cantilevered portion. The tail-end connection assembly includes a tail seat 7, with a connecting seat 8 at the end of the tail seat. Both ends of the connecting seat extend outward from the tail seat, and an array of tail-end tie rods 9 are provided between the connecting seat and the tail seat. Furthermore, an array of boom tie rods 10 are provided between the segments at the head end and the segments at the tail end of the boom body. A reinforcing frame 11 is provided inside the tail seat corresponding to the tail seat tie rod fixing seat, and each tail seat tie rod fixing seat is simultaneously connected to the reinforcing frame and the tail seat side plate.

[0029] The split sections are inverted trapezoidal in shape, with an internal cavity 20. Each split section has a split-section connecting flange 12 at both ends, and adjacent split sections are fixed together by bolts 13. The base has a base connecting flange 14 at the end facing the split section, and this base connecting flange is fixed to the split-section connecting flange of the split section located at the head end of the boom body by bolts. The tailstock has a tailstock connecting flange 15 at the end facing the split section, and this tailstock connecting flange is fixed to the split-section connecting flange of the split section located at the tail end of the boom body by bolts.

[0030] Two sets of boom tie rods are symmetrically arranged on the boom body. Two tie rod head fixing seats 16 are symmetrically provided on the split at the front end of the boom body, and two tie rod tail fixing seats 17 are symmetrically provided on the split at the rear end of the boom body.

[0033] This invention features a rationally designed structure. Through a modular design, it can be manufactured in sections, reducing production difficulty. It can be assembled and installed on-site, cleverly solving the various inconveniences encountered during transportation due to its large size, making it more practical. Because the main structural components of the stacker-reclaimer's boom are primarily made of high-strength steel, the assembled frame structure has a stable internal cavity structure. Compared to the integral stacker-reclaimer booms of existing technologies, this invention effectively reduces the overall weight. The length and angle of the boom can be adjusted according to actual needs to meet different scales of stacking and reclaiming requirements.

[0034] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention.
