Description

Technical Field

[0001] The present invention relates to the technical field of PVG conveyor belts, and specifically to an automatically self-aligning PVG conveyor belt. Background Art

[0002] The PVG flame-retardant conveyor belt is a rubber-faced solid-core flame-retardant conveyor belt, and due to its excellent performance, it is widely used in mining transportation and other industrial environments that require high safety.

[0003] However, the existing PVG flame-retardant conveyor belt needs to rely on the driving roller for assistance. Since the PVG flame-retardant conveyor belt can rotate uniformly on the driving roller after being tightened, when the ore is placed on the top surface of the PVG flame-retardant conveyor belt and is being transported outward, after the ore accumulates, the PVG flame-retardant conveyor belt will be pressed, causing its two side edges to slip off the driving roller. At the same time, as the PVG flame-retardant conveyor belt continues to be pressed and deforms, abnormal jitter will occur when the PVG flame-retardant conveyor belt rotates on the driving roller.

[0004] In view of this, an automatically self-aligning PVG conveyor belt is designed to solve the above problems. Summary of the Invention

[0021] To make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with the specific implementation manners and with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0022] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention.

[0023] The following describes an automatically self-aligning PVG conveyor belt provided by some embodiments of the present invention in conjunction with the accompanying drawings. Embodiment 1:

[0024] Combined with Figures 1 to 10As shown in the figure, an automatically rectifying PVG conveyor belt provided by the present invention includes a beam rod 100, a belt edge strengthening mechanism 200 arranged outside the beam rod 100, four groups of belt bottom rotation and pressing mechanisms 300 arranged on the belt edge strengthening mechanism 200, four groups of belt top stability increasing mechanisms 400 arranged on the belt edge strengthening mechanism 200, and a conveying component 500 arranged between the four groups of belt top stability increasing mechanisms 400 and the belt edge strengthening mechanism 200. The belt edge strengthening mechanism 200 is used to provide a stable support platform for the four groups of belt bottom rotation and pressing mechanisms 300 and the four groups of belt top stability increasing mechanisms 400. The belt edge strengthening mechanism 200 cooperates with the belt top stability increasing mechanism 400 to provide side rectifying protection for the conveying component 500. The belt bottom rotation and pressing mechanism 300 is used to provide centering anti-deviation protection for the conveying component 500.

[0025] The belt edge strengthening mechanism 200 includes a load-bearing plate 2101 arranged outside the beam rod 100 and two clamping sleeves 210, a plurality of first clamping seats 2102 arranged outside the load-bearing plate 2101, a mother pipe 230 movably installed in the first clamping seats 2102, a first spring 2301 arranged in the mother pipe 230, and a sub-rod 2302 movably installed inside the mother pipe 230 and pressing on the first spring 2301; The other end of the sub-rod 2302 is movably installed with a second clamping seat 240, and a bottom limit plate 2401 is installed outside the second clamping seat 240; The belt edge strengthening mechanism 200 further includes a plurality of limit strips 2104 arranged on the load-bearing plate 2101, two auxiliary pressing strip plates 2103 arranged on both sides of the load-bearing plate 2101, four protective outer frames 220 installed in the load-bearing plate 2101, and a plurality of bottom rollers 2403 arranged inside the bottom limit plate 2401; The belt top stability increasing mechanism 400 includes a traction plate 4101 arranged between the limit strips 2104 and the auxiliary pressing strip plates 2103, a top limit plate 420 arranged at the outer end of the traction plate 4101, a support plate 410 arranged at the bottom of the traction plate 4101, and the support plate 410 is located in a transverse groove, an end post 430 installed on the traction plate 4101, a compression spring 4303 arranged outside the end post 430, a plug 4301 installed at the outer end of the end post 430, and a gasket 4302 arranged on the end post 430 and pressing on the compression spring 4303; The conveying component 500 includes a belt edge pressure-resistant member 510 arranged between the top limit plate 420 and the bottom limit plate 2401 and a conveyor belt 520 arranged inside the belt edge pressure-resistant member 510; Two limit grooves 2402 are formed inside the bottom limit plate 2401, and a rectangular protrusion adapted to be clamped to the belt edge pressure-resistant member 510 is arranged outside the bottom limit plate 2401.

[0026] The device is pre-arranged in a selected area within the mine pit, and the edge-bearing compression member 510 is arranged outside multiple evenly distributed edge-reinforcing mechanisms 200 and multiple top-stabilizing mechanisms 400. After the edge-bearing compression member 510 is driven to rotate uniformly along the inside of the mine pit, the edge-bearing compression member 510 during uniform rotation can continuously transfer the ore outwards. During the rotation of the edge-bearing compression member 510, after the top part of the edge-bearing compression member 510 deforms due to the pressure of the ore, the cross plate 3202 and the base 310 squeezed by the deformed part of the edge-bearing compression member 510 will tilt along the jacket 210, and the bottom slide frame 3103 and the pin 3104 arranged at the bottom of the base 310 will apply a traction force to the support plate 410 and the traction plate 4101. Finally, after the middle part of the edge-bearing compression member 510 deforms, its two sides can be effectively clamped by the bottom limit plate 2401 and the top limit plate 420; Thereby avoiding the problem that the ore increases the pressure on the edge-bearing compression member 510 and causes its side to fall off the existing transmission roller; After the ore on the surface of the edge-bearing compression member 510 is discharged, the edge-bearing compression member 510 without pressure can be provided with an effective reset support force by the cross plate 3202 and two second springs 3203, thereby ensuring the rapid reset and straightening of the edge-bearing compression member 510 after the release of force. Embodiment 2:

[0027] Combined with Figures 3 to 10 As shown, on the basis of Embodiment 1, the conveying assembly 500 further includes a first anti-deviation bottom support 530 and a second anti-deviation bottom support 540, and the first anti-deviation bottom support 530 and the second anti-deviation bottom support 540 are integrally in an L-shaped structure; The bottom rotation and pressing mechanism 300 includes a base 310 arranged on the jacket 210, four stud bolts 3101 arranged on the outer wall of the base 310, a protective outer plate 330 arranged outside two of the stud bolts 3101, a nut 3102 arranged outside the stud bolts 3101 and pressing on the protective outer plate 330, a bearing 3301 arranged inside the protective outer plate 330, a horizontal shaft 3302 installed inside the bearing 3301 and placed horizontally, a hub 3303 movably installed at the inner end of the horizontal shaft 3302, a non-slip tread 3304 arranged outside the hub 3303, two bottom slide frames 3103 arranged on the base 310, and a chute is opened inside the bottom slide frame 3103, and a pin 3104 is arranged in the chute, a vertical rod 320 arranged inside the base 310, a cross plate 3202 installed at the top end of the vertical rod 320, a buckle 3201 installed at the bottom end of the vertical rod 320, and a second spring 3203 arranged outside the vertical rod 320 and bearing on the cross plate 3202; The hub 3303 and the non-slip tread 3304 are used to provide anti-detachment protection for the inner ends of the first anti-deviation bottom support 530 and the second anti-deviation bottom support 540; The transverse plate 3202 is adapted to fit the inner side of the conveyor belt 520, and is used to provide enhanced stability support for the conveyor belt 520 after discharging materials. A transverse groove is provided inside the auxiliary pressure strip plate 2103, and the bottom sliding frame 3103 and the traction plate 4101 are adapted to penetrate into the transverse groove.

[0028] Preferably, the nut 3102 provided on the stud 3101 is used to effectively clamp the protective outer plate 330. Among them, the inner ends of the first anti-deviation bottom support 530 and the second anti-deviation bottom support 540 are located outside the two second springs 3203, and the combined hub 3303 and the anti-slip tread 3304 are used to provide anti-disconnection protection for the inner ends of the first anti-deviation bottom support 530 and the second anti-deviation bottom support 540. After the belt-edge pressure-resistant member 510 is assisted in rotation by the existing transmission roller, the belt-edge pressure-resistant member 510 in uniform rotation can effectively rotate along the outside of the transverse plate 3202. When the ore is placed on the top part of the belt-edge pressure-resistant member 510 and transferred out of the mine pit, the ore piled up on the surface of the belt-edge pressure-resistant member 510 and deviated from the center will be supported and protected by the transverse plate 3202 and the two second springs 3203, thereby reducing the pressure borne by the belt-edge pressure-resistant member 510. Embodiment 3:

[0029] Combined with Figures 3 to 10 As shown, on the basis of Embodiment 1, both the bottom roller 2403 and the top roller 4201 are composed of a assisting pulley and a vertical rod, and the outer wall of the assisting pulley is provided with a rough surface for increasing the pressure-bearing protection for the belt-edge pressure-resistant member 510; A rectangular convex surface is provided on the side of the top limit plate 420 facing the belt-edge pressure-resistant member 510, and a plurality of top rollers 4201 are arranged inside the rectangular convex surface.

[0030] Preferably, the bottom limit plate 2401 and the top limit plate 420 are symmetrically distributed in the vertical direction and are used to provide effective clamping force for the rectangular grooves on both sides of the belt-edge pressure-resistant member 510, and the uniformly distributed plurality of bottom rollers 2403 and the plurality of top rollers 4201 can provide side anti-disconnection pressure-bearing protection for the belt-edge pressure-resistant member 510.

[0031] The traction plate 4101 is adapted to penetrate into the limit groove 2402; A groove is provided inside the clamping sleeve 210, and the auxiliary pressure strip plate 2103 is adapted to be snap-fitted into the groove; The pin 3104 is movably installed at one end of the support plate 410 away from the traction plate 4101; The surface of the transverse plate 3202 is provided with a rubber outer layer for increasing the frictional resistance; The anti-slip tread 3304 is made of silica gel material.

[0032] Preferably, the traction plate 4101 is fixed to the top limit plate 420 by welding, and the limiting strip 2104 and the auxiliary pressing strip plate 2103 can provide effective guiding force for the supporting plate 410 and the traction plate 4101; Specifically, when the edge-bearing compression member 510 rotates at a constant speed and passes through the cross plate 3202, the edge-bearing compression member 510 during compression can obtain the deviation correction protection of the cross plate 3202, and cooperate with the limiting protection of the two groups of hubs 3303 and the anti-slip tread 3304, so as to avoid the problem of deviation or falling off of the edge-bearing compression member 510 due to being pressed in the middle.

[0033] The working principle and usage process of the present invention: The device is arranged at a selected position of the pit according to the depth of the mine pit in advance; When the conveyor belt 520 is assisted to rotate by the driving roller, the first anti-deviation bottom bracket 530 and the second anti-deviation bottom bracket 540 fixed to both sides of the conveyor belt 520 by the two edge-bearing compression members 510 will slide uniformly along the inner side of the beam rod 100. When the top part of the conveyor belt 520 rotates uniformly in the mine pit, the ore can then be transferred to the top part of the conveyor belt 520, and the uniformly rotating conveyor belt 520 can effectively transfer the ore out of the mine pit; Since the accumulated ore will cause pressure on the top part of the conveyor belt 520, the conveyor belt 520 will be inclined to a certain extent after being heavily pressed. After the conveyor belt 520 is driven and vibrates under pressure, the pressed conveyor belt 520 will cause a deviation and sliding trend on its two sides. As the top part of the conveyor belt 520 tilts to one side, one of the cross plates 3202 will be pressed and drop downward, and the base 310 will tilt laterally with the clamp sleeve 210 as the axis. At this time, the bottom sliding frame 3103 and the pin 3104 installed at the bottom of the base 310 will apply a traction force to the supporting plate 410. Finally, the tractioned supporting plate 410 will drive the top limit plate 420 and multiple top rollers 4201 to adapt and press the top of the edge-bearing compression member 510, and the main pipe 230 and the sub-rod 2302 arranged on the first clamp seat 2102 will apply an upward lifting force to the bottom limit plate 2401. At this time, the bottom limit plate 2401 and the top limit plate 420 can limit and clamp the horizontally placed edge-bearing compression member 510; The two edge-bearing compression members 510 and the conveyor belt 520 showing a tendency to tilt will be forcibly tightened, and the first anti-deviation bottom bracket 530 and the second anti-deviation bottom bracket 540 arranged on one side of the conveyor belt 520 will be adapted and pressed by the anti-slip tread 3304 and the hub 3303. At this time, the entire conveyor belt 520 can provide effective deviation correction protection for the ore transfer.

[0034] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the claims and their equivalents.
