Description

Technical Field

[0001] This invention belongs to the field of belt conveyor technology, specifically relating to a rapid laying platform for belt conveyor telescopic idler groups. Background Technology

[0002] Belt conveyors, also known as belt conveyors or simply belt conveyors, are commonly used conveying equipment for bulk material transportation. In practical applications, especially in coal mine roadways and tunnel excavation, belt conveyors often need to continuously extend longitudinally or move laterally as the working face is excavated. The relocation of belt conveyors is a time-consuming and labor-intensive task, especially the longitudinal extension. This requires laying numerous intermediate frames and supports to hold the conveyor belt idlers together. Currently, the intermediate frames and supports for the extension section of the belt conveyor are laid manually, one set at a time, which is extremely time-consuming and labor-intensive. It typically requires a large number of personnel, resulting in high labor intensity, significant time commitment, and high labor costs. Furthermore, laying the intermediate frames and supports requires the belt conveyor to be shut down for extended periods, which greatly impacts the mining efficiency and economic benefits of coal mines, or seriously affects the construction schedule of tunnel excavation. Summary of the Invention

[0003] In response to the above situation, the present invention provides a rapid laying platform for the telescopic idler roller assembly of a belt conveyor, which can realize rapid laying of the intermediate frame legs of the telescopic section of the belt conveyor without stopping the machine, greatly saving the time spent on the extension operation of the belt conveyor and greatly improving the working efficiency of the belt conveyor.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A rapid laying platform for a belt conveyor with telescopic idler rollers includes a conveyor belt, a laying platform that can slide back and forth along the conveyor direction, and a traction device for dragging the laying platform. The laying platform is a gantry truss structure. A longitudinal sliding shoe is provided below the laying platform. A support leg slide for storing telescopic standard sections is provided at the front of the laying platform. The support leg slide can extend laterally from the side of the laying platform.

[0006] The telescopic standard section includes three pairs of legs arranged from front to back. A telescopic hinged chain plate connects adjacent legs. Each leg is detachably equipped with an upper and lower idler roller for supporting the conveyor belt. A track groove is provided at the bottom of the leg carriage along the front-to-back direction. The bottom of the legs of the telescopic standard section is placed within the track groove. Multiple sets of telescopic standard sections can be placed on the leg carriage in multiple stages. Each set of telescopic standard sections can be slid and removed sequentially along the track groove. A limiting chain link connects each subsequent telescopic standard section to the preceding one to limit the interval between them. A positioning chain link connects the preceding telescopic standard section to the platform for a fixed connection. The front of the platform is connected to the traction device via a traction linkage.

[0007] Preferably, the traction device is a tracked self-propelled tail section, and the traction link is a hydraulic cylinder. Under the traction of the tracked self-propelled tail section, and combined with the drag-reducing sliding effect of its bottom longitudinal slippers, the laying platform achieves overall longitudinal movement.

[0008] Preferably, the laying platform consists of multiple uprights symmetrically arranged on the left and right, two sets of longitudinal beams mounted on top of the uprights, and multiple crossbeams connecting the two sets of longitudinal beams. Telescopic rollers are installed on the uprights at the front of the laying platform, and multiple sets of idlers are installed between the two sets of longitudinal beams to support the telescopic conveyor belt that runs along the laying platform.

[0009] Preferably, both the upper and lower idlers are hinged idlers, and the rear of the laying platform is provided with an idler group slide for storing the hinged idlers. The idler group slide can extend laterally from the side of the laying platform, and a horizontal slide rail for the idler group is provided above the rear of the laying platform. The top of the idler group slide is slidably connected to the horizontal slide rail for the idler group.

[0010] Preferably, the support leg assembly slide is a cuboid frame structure, and a pair of support leg transverse slides arranged in the left-right direction are fixed above the front part of the platform. The top of the support leg assembly slide is slidably connected to the support leg assembly transverse slides. The support leg assembly transverse slides are a pair of channel steels facing each other and fixedly suspended above the platform in the left-right direction. The front and rear sides of the top of the support leg assembly slide are slidably fitted into the grooves of the two channel steels respectively.

[0011] Preferably, the track groove of the outrigger carriage is provided with multiple unpowered rollers for conveying the unloading telescopic standard section to the rear; the hinged chain plate is a scissor-type telescopic structure, and a guide rod is provided between two adjacent outriggers of the telescopic standard section. On the one hand, it is used to guide the telescopic movement of the hinged chain plate, and on the other hand, it also has the function of preventing the outriggers from tipping over. The front end of the guide rod is fixedly connected to the front outrigger, and the rear end of the guide rod slides through the rear outrigger. A tapered guide surface is also provided at the rear end of the guide rod.

[0012] The present invention also includes other components that enable its normal use, all of which are conventional means in the art. In addition, devices or components not limited in the present invention, such as conveyor belts, telescopic rollers, upper and lower idlers, support legs, slippers, scissor telescopic structures, and control systems for tracked self-propelled tail sections and hydraulic telescopic rods, all adopt existing technologies in the art.

[0013] The beneficial effects of this invention are as follows:

[0022] Example

[0023] like Figure 1As shown, a rapid laying platform for a belt conveyor telescopic idler group includes a conveyor belt 1, a laying platform 2 capable of sliding back and forth along the conveyor direction, and a traction device 3 for dragging the laying platform. The laying platform is a gantry truss structure. A longitudinal sliding shoe 4 is provided below the laying platform. A support leg slide 5 for storing telescopic standard sections is provided at the front of the laying platform. The support leg slide can extend laterally from the side of the laying platform.

[0024] The telescopic standard section includes three pairs of support legs 6 arranged from front to back. A telescopic hinged chain plate 7 connects two adjacent support legs. Each support leg is detachably equipped with an upper idler roller 8 and a lower idler roller 9 for supporting the conveyor belt. A track groove 10 is provided at the bottom of the support leg slide along the front-to-back direction. The bottom of the support legs of the telescopic standard section is placed in the track groove. Multiple sets of telescopic standard sections can be placed on the support leg slide in multiple batches. Each set of telescopic standard sections can be slid and removed sequentially along the track groove. A limiting chain link 11 is connected between the previous telescopic standard section and the next telescopic standard section to limit the interval distance between the previous and next telescopic standard sections. A positioning chain link 12 is connected between the previous telescopic standard section and the laying platform for fixed connection between the previous telescopic standard section and the laying platform. The front of the laying platform is connected to the traction device through a traction link 13.

[0025] The traction device is a tracked self-propelled tail section, and the traction linkage is a hydraulic cylinder. Under the traction of the tracked self-propelled tail section, combined with the drag-reducing sliding effect of its bottom longitudinal slippers, the laying platform achieves overall longitudinal movement.

[0026] The paving platform consists of multiple uprights 14 arranged symmetrically on the left and right, two sets of longitudinal beams 15 erected on top of the uprights, and multiple crossbeams 16 connecting the two sets of longitudinal beams. Telescopic rollers 17 are installed on the uprights at the front of the paving platform, and tail rollers 18 are installed on the tail of the tracked self-propelled machine. Multiple sets of idlers are installed between the two sets of longitudinal beams to support the telescopic conveyor belt on the paving platform. Furthermore, the rear of the longitudinal beams is designed with a gradually decreasing slope to facilitate better transfer of the telescopic conveyor belt to the pre-laid telescopic standard section after the paving platform moves forward.

[0027] like Figure 3As shown, both the upper and lower idlers are hinged idlers. A roller set carriage 19 for storing the hinged idlers is provided at the rear of the laying platform. The roller set carriage can extend laterally from the side of the laying platform. A roller set transverse slide 20 is provided above the rear of the laying platform, and the top of the roller set carriage is slidably connected to the roller set transverse slide. Multiple sets of hinged idlers can be detachably placed on the roller set carriage. When loading hinged idlers onto the roller set carriage, the roller set carriage is first slid out from the side of the laying platform to facilitate the addition of hinged idlers, and then the roller set carriage is retracted into the laying platform. After the laying platform has moved and laid a section of the telescopic standard section, the corresponding number of hinged idlers can be unloaded from the roller set carriage and installed on the upper and lower idler mounting positions provided on each support leg of the telescopic standard section.

[0028] like Figure 2 As shown, the support leg assembly slide is a cuboid frame structure. A pair of lateral slide rails 21, arranged in the left-right direction, are fixed above the front of the laying platform. The top of the support leg assembly slide is slidably connected to the lateral slide rails. The lateral slide rails are a pair of channel steels facing each other and fixedly suspended above the laying platform in the left-right direction. The front and rear sides of the top of the support leg assembly slide are slidably fitted into the grooves of the two channel steels. Hydraulic telescopic rods for laterally pushing and pulling the support leg assembly slide and the idler roller assembly slide are installed on the laying platform.

[0029] The track groove of the outrigger carriage is equipped with multiple non-powered rollers 22 for conveying the unloading telescopic standard section to the rear. The hinged chain plate is a scissor-type telescopic structure. A guide rod 23 is also provided between two adjacent outriggers of the telescopic standard section. On the one hand, it is used to guide the telescopic movement of the hinged chain plate, and on the other hand, it also has the function of preventing the outriggers from tipping over. The front end of the guide rod is fixedly connected to the front outrigger, and the rear end of the guide rod slides through the rear outrigger. A tapered guide surface is also provided at the rear end of the guide rod.

[0030] like Figure 4 As shown, when loading the telescopic standard section onto the outrigger carriage, the outrigger carriage is pushed laterally and slides out from the side of the laying platform. Then, the telescopic standard section is placed onto the outrigger carriage using a forklift. The outrigger carriage is then retracted into the laying platform. Only one telescopic standard section is placed on the outrigger carriage at a time, and its hinge chain plate is in a retracted state at this time.

[0031] like Figure 5 As shown, as the tracked self-propelled machine pulls the laying platform forward, the telescopic standard section is dragged off the support leg slide. Due to the pulling of the front and rear support legs of the telescopic standard section by the positioning chain and the limiting chain respectively, its hinged chain plate is gradually pulled open until it is fully extended. Then, the upper and lower idlers are installed on the telescopic standard section, and the rapid laying of the telescopic standard section can be completed.

[0032] The technical solutions of the present invention are not limited to the specific embodiments described above. Without departing from the scope and spirit of the described embodiments, many modifications and changes will be obvious to those skilled in the art. Any technical modifications made within the spirit and principles of the present invention will fall within the protection scope of the present invention.
