Description

Technical Field

[0001] This utility model relates to the field of belt conveyor technology, specifically to a novel telescopic suspended belt conveyor with a trough. Background Technology

[0002] Traditional belt conveyors require a foundation to be laid first, and anchor bolts or steel plates to be pre-embedded before installing each component. This process is labor-intensive and time-consuming. In underground tunnel excavation and mining roadway projects, there are difficulties such as narrow spaces and soft ground that make it difficult to lay rigid foundation structures. Traditional belt conveyors can no longer meet the actual work requirements. Utility Model Content

[0003] To address the aforementioned technical problems of existing traditional belt conveyors, the purpose of this utility model is to provide a novel telescopic suspended belt conveyor for roadways. Suspended on a roadway support, its novel structure, lightweight and easy-to-assemble / disassemble body makes it more suitable for applications in underground mining roadways, tunnel excavation, and other engineering projects. It can adapt to complex terrains such as crossing rivers and bridges, occupies little space, does not interfere with other equipment, minimizes construction interference, saves space, provides ample operating space, and features a rigid suspended body, minimizing damage or collapse, thus improving the reliability and stability of the belt conveyor.

[0004] To achieve the above objectives, this utility model provides a novel telescopic suspended belt conveyor for roadways, comprising a longitudinal beam, several upper idler frames, several lower idler frames, a conveyor belt, and a telescopic suspension assembly. The several upper idler frames and several lower idler frames are arranged opposite to each other and are respectively connected to the longitudinal beam by a detachable connection. The upper idler frames are connected to upper trough-shaped idlers, and the lower idler frames are connected to lower flat idlers. The conveyor belt is wound around the several upper trough-shaped idlers and several lower flat idlers to form a closed loop. The longitudinal beam is suspended on the roadway support by the telescopic suspension assembly, which can drive the longitudinal beam to move vertically by telescopic extension.

[0005] Furthermore, the conveyor belt is a rubber belt, which is strip-shaped and has an overall structure of a closed loop.

[0006] Furthermore, the upper roller frame, the lower roller frame, and the longitudinal beam are detachably connected by E-pins.

[0007] Furthermore, the bottom of the upper roller frame and the top of the lower roller frame are provided with inserts, and the longitudinal beam is provided with tube seats for inserting the inserts of the upper roller frame and the lower roller frame. The upper roller frame and the lower roller frame are respectively inserted into the tube seats through the inserts. The inserts and tube seats are provided with corresponding insertion holes for E-type pins. Then, the E-type pins are passed through the inserts and the insertion holes on the tube seats in sequence to detachably connect the longitudinal beam with the upper roller frame and the lower roller frame.

[0008] Furthermore, the retractable suspension assembly includes a circular chain and an adjustable turnbuckle assembly. One end of the adjustable turnbuckle assembly is connected to the longitudinal beam, and the other end of the adjustable turnbuckle assembly is connected to one end of the circular chain. The other end of the circular chain is connected to the tunnel support. The vertical height of the longitudinal beam can be adjusted through the adjustable turnbuckle assembly.

[0009] Furthermore, the adjustable turnbuckle assembly includes a bolt body, a first adjusting rod, and a second adjusting rod.

[0010] The bolt body has a threaded screw assembly hole at each end. The first adjusting rod and the second adjusting rod have external threads on their surfaces and are screwed into the assembly holes at both ends of the bolt body. The first adjusting rod and the second adjusting rod on the outer side of both ends of the bolt body are respectively provided with a first fastening nut and a second fastening nut.

[0011] The end of the first adjusting rod furthest from the bolt body is connected to a connecting ring, which is connected to a circular chain. The end of the second adjusting rod furthest from the bolt body is connected to a shackle, which is connected to a longitudinal beam.

[0012] By rotating the first adjusting rod and the second adjusting rod, the first adjusting rod and the second adjusting rod can be moved closer to each other or further away from each other, thereby achieving vertical adjustment. By rotating the first fastening nut and the second fastening nut to abut against the bolt body, the first adjusting rod and the second adjusting rod can be fixed after adjustment.

[0013] The novel telescopic suspended belt conveyor provided by this utility model, suspended on the roadway support, is more suitable for underground mining roadway and tunnel excavation projects due to its novel structure, lightweight and easy-to-disassemble body structure.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0023] See Figure 1 , Figure 2 The diagram shown is a structural schematic of the novel telescopic suspended belt conveyor provided by this utility model.

[0024] As shown in the figure, the novel telescopic hanging belt conveyor provided by this utility model includes five components: longitudinal beam 100, several upper idler frames 200, several lower idler frames 300, conveyor belt 400, and telescopic hanging assembly 500.

[0025] Among them, the longitudinal beam 100 is the main structure and is used to support other components.

[0026] Furthermore, several upper roller frames 200 and several lower roller frames 300 are arranged opposite to each other and are respectively connected to the longitudinal beam 100 by a detachable connection method;

[0027] The upper idler frame 200 is connected to the upper trough idler 600, the lower idler frame 300 is connected to the lower flat idler 700, and the conveyor belt 400 is wound around several upper trough idlers 600 and several lower flat idler groups 700 to form a closed loop.

[0028] The longitudinal beam 100 is suspended on the roadway support by a telescopic suspension assembly 500. The telescopic suspension assembly 500 can move the longitudinal beam 100 vertically by extending and retracting.

[0029] Compared to existing technologies, the novel telescopic suspended belt conveyor provided in this solution, suspended on the roadway support, is more suitable for underground mining roadways, tunnel excavation, and other engineering projects due to its novel structure, lightweight and easy-to-disassemble body structure. It can also adapt to complex terrains such as crossing rivers and bridges, occupy little space, and does not interfere with other equipment, thus minimizing construction interference, saving space, providing a large operating space, and having good rigidity of the suspended body, with the body rarely experiencing damage or collapse, thereby improving the reliability and stability of the belt conveyor.

[0030] Specifically, a number of upper trough-type idlers 600 and a number of lower flat idlers 700 are arranged equidistantly on the longitudinal beam 100. The spacing between adjacent upper trough-type idlers 600 is preferably 1.5 meters, and the spacing between adjacent lower flat idlers 700 is preferably 3 meters.

[0031] The conveyor belt 400 is a rubber belt, which is strip-shaped and has an overall structure of a closed loop.

[0032] Furthermore, the upper roller frame 200, the lower roller frame 300, and the longitudinal beam 100 are detachably connected by E-type pins 800, making disassembly and adjustment more convenient.

[0033] E-type pins are pins shaped like the letter E, and are a standard technique, so they will not be described in detail here.

[0034] like Figure 3 The upper roller frame 200 has inserts 210 at its bottom and the lower roller frame 300 has inserts 210 at its top. The longitudinal beam 100 has tube seats 110 for inserting the upper roller frame 200 and the lower roller frame 300. In actual assembly, the upper roller frame 200 and the lower roller frame 300 are inserted into the tube seats 110 through the inserts 210. The inserts 210 and the tube seats 110 have corresponding insertion holes for the E-pins 800. Then, the E-pins 800 are passed through the insertion holes on the inserts 210 and the tube seats 110 in sequence to detachably connect the longitudinal beam 100 with the upper roller frame 200 and the lower roller frame 300.

[0035] The telescopic suspension assembly 500 includes a circular chain 510 and an adjustable turnbuckle assembly 520. One end of the adjustable turnbuckle assembly 520 is connected to the longitudinal beam 100, and the other end of the adjustable turnbuckle assembly 520 is connected to one end of the circular chain 510. The other end of the circular chain 510 is connected to the tunnel support. The circular chain 510 and the tunnel support are preferably connected by anchor bolts.

[0036] The vertical height of the longitudinal beam 100 can be adjusted using the adjustable turnbuckle assembly 520.

[0037] Specifically, such as Figure 4 The adjustable turnbuckle assembly 520 includes a bolt body 521, a first adjusting rod 522, and a second adjusting rod 523.

[0038] The bolt body 521 has a screw mounting hole with internal thread at each end. The first adjusting rod 522 and the second adjusting rod 523 have external threads on their surfaces and are screwed into the mounting holes at both ends of the bolt body 521 respectively. The first adjusting rod 522 and the second adjusting rod 523 on the outer side of both ends of the bolt body 521 are respectively provided with a first fastening nut 524 and a second fastening nut 525.

[0039] The end of the first adjusting rod 522 away from the bolt body 521 is connected to a connecting ring 526, which is connected to the circular chain 510. The end of the second adjusting rod 522 away from the bolt body 521 is connected to a shackle 527, which is connected to the longitudinal beam 100.

[0040] By rotating the first adjusting rod 522 and the second adjusting rod 523, the first adjusting rod 522 and the second adjusting rod 523 can be moved closer to each other or further away from each other, thereby achieving vertical adjustment. By rotating the first fastening nut 524 and the second fastening nut 525 to abut against the bolt body 521, the adjusted first adjusting rod 522 and the second adjusting rod 523 can be fixed.

[0041] Furthermore, when the entire conveyor is a straight section, the stress on each suspension point of the suspended body is relatively simple, consisting only of the sum of the weight of the material, belt, and various components of the body per unit length. With appropriate consideration of certain impact loads, the reliability of the body is relatively easy to achieve. However, when the continuous conveyor has both straight sections and horizontal turning sections, the stress on each suspension point of the suspended body becomes more complex in the horizontal turning sections. As the body extends and the conveying capacity changes, the tension on each suspension point at the turning point is constantly changing. If the maximum stress on the suspension points in the turning section of the conveyor is not considered during the design calculation, and the locking screw buckle is selected only based on the stress on the suspension points in the straight section of the conveyor, the selected locking screw buckle may have insufficient stress.

[0042] Taking 3 meters as a research unit, a stress analysis is performed. Within the 3-meter unit, there are: 2 sets of upper idler roller frames 200, 2 sets of upper trough idler rollers 600, 1 set of longitudinal beams 100, 2 sets of lower idler roller frames 200, and one lower flat idler roller 700. The material mass per meter is X3, and the mass of the E-type pin is negligible.

[0043] Based on the weight indicated in the project drawings:

[0044] The weight of two sets of upper idler roller frames (200mm each) is 28.24 x 2 = 56.48 kg.

[0045] Two sets of upper trough type idler rollers 600: 11 x 6 = 66 kg

[0046] One set of longitudinal beams, 100mm: 38.86 x 2 = 77.7kg

[0047] Two sets of lower idler roller frames, 200: 25.3 x 2 = 50.6 kg

[0048] 1 lower flat idler roller 700: 29kg

[0049] Mass of 3 meters of material: 88.18 x 3 = 264.54 kg

[0050] The total weight of all the above components is approximately 550 kg. Considering a certain impact load and giving a safety margin of 1.5, the total weight is 550 * 1.5 = 825 kg. All this weight is borne by four adjustable turnbuckle assemblies 520 and four circular chain 510. Therefore, each needs to bear a weight of 825 / 4 = 206.25 kg. 206.25 kg is equivalent to 2.06 kN of force, meaning that each adjustable turnbuckle assembly 520 and circular chain 510 needs to withstand 2.06 kN of force.

[0051] The preferred choice for this solution is the adjustable turnbuckle assembly 520, model KUUD-12, grade T, which conforms to the national standard GB / T3818-2013. Its safe working load is 10.1KN and its minimum breaking load is 51KN, which fully meets the requirements.

[0052] This solution preferably uses a galvanized 10*35 circular link chain as specified in JB / T8108.2-1999, with a diameter of φ10 and P=35 (customizable). The material is 20Mn2 and it has been hot-dip galvanized. Its working tensile strength is greater than 20KN, which meets the requirements.

[0053] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
