[0002] Currently, the intermediate frame of a mobile belt conveyor in open-pit mines is anchored to the rail sleepers with bolts. This bolted anchoring to the rail sleepers requires relocation to prevent the intermediate frame from deforming, requiring removal and reinstallation of the anchors. This is slow and time-consuming. Utility Model Content
[0003] In view of this, the present invention provides a displaceable belt conveyor and a flexible connection assembly thereof, thereby solving or at least alleviating one or more of the above-mentioned problems and other problems existing in the prior art.
[0004] In order to achieve the aforementioned objectives, the first aspect of the present invention provides a flexible connection assembly for a displaceable belt conveyor, wherein the displaceable belt conveyor includes an intermediate frame equipped with rollers, the intermediate frame is fixed on a sleeper, and the sleeper is set to the guide rail of the displaceable belt conveyor through the flexible connection assembly; the flexible connection assembly includes: a rail clamp pin rotatably connected to the sleeper, the rail clamp pin having a protrusion; the protrusion is configured to cooperate with the guide rail of the conveyor so that the sleeper is clamped on the guide rail; the rail clamp pin is configured to have a gap between it and the sleeper, so that the rail clamp pin can achieve a limited angle of rotation relative to the guide rail.
[0005] In the flexible connection assembly as described above, optionally, it further includes opposite clamping plates fixed on the sleeper; the rail clamping pin is clamped between the opposite clamping plates and is rotatably connected to the clamping plates.
[0006] In the flexible connection assembly as described above, optionally, the track clamp pin and the relative clamp plate both have through holes, and bolts pass through the through holes of the track clamp pin and the relative clamp plate to connect the track clamp pin and the relative clamp plate, and are fixed with nuts.
[0007] In the flexible connection assembly as described above, optionally, the rail clamp pin has an end surface on a side close to the sleeper, and there is the gap between the end surface and the sleeper.
[0008] In the flexible connection assembly as described above, optionally, the track clamp pin is formed with the protrusion on the side facing the guide rail, the protrusion and the sleeper form a gap, and the gap is embedded with at least part of the components of the guide rail, so that the sleeper is clamped on the guide rail.
[0009] In the flexible connection assembly as described above, optionally, there is a pair of track clamping pins, which are respectively arranged on both sides of the guide rail.
[0010] To achieve the aforementioned objectives, the second aspect of the present invention provides a displaceable belt conveyor, comprising: an intermediate frame equipped with rollers, the above-mentioned flexible connection assembly and a guide rail, wherein the intermediate frame is fixedly mounted on the sleeper, and the sleeper is mounted on the guide rail through the flexible connection assembly.
[0011] In the aforementioned displacement belt conveyor, optionally, at least two limiting devices are fixed on the guide rail, and the at least two limiting devices are located on both sides of the sleeper.
[0012] In the aforementioned displaceable belt conveyor, optionally, one end of the limiting device is fixed on the guide rail of the displaceable belt conveyor, and the other end of the limiting device extends downward to form a blocking portion to limit the sliding of the sleeper along the guide rail.
[0013] In the aforementioned displaceable belt conveyor, optionally, the limiting device is a pair of limiting members, each limiting member has a groove on one side that engages with the guide rail, and the other side hangs out of the guide rail and is fixed to another opposite limiting member.
[0014] The intermediate frame of the present invention is fixed to the sleeper, and the sleeper is limitedly set on the guide rail of the conveyor through the above-mentioned flexible connection assembly. In other words, the intermediate frame is limitedly set on the guide rail of the conveyor through the sleeper; when the displaceable belt conveyor needs to be displaced, the intermediate frame can be allowed to move a small amount of limited position relative to the guide rail in a direction perpendicular to the guide rail.
[0015] The flexible connection assembly adopts a detachable structure, which is simple to install and easy to dismantle.
[0016] The present invention further provides a displacement belt conveyor, which includes the flexible connection assembly and thus also has the above advantages.
[0017] In addition, the guide rails of the removable belt conveyor are equipped with limiters. These limiters on either side of the sleeper restrict the movement of the intermediate frame along the guide rails. When the removable belt conveyor needs to be relocated, the intermediate frame can move slightly relative to the guide rails, either along the guide rails or within a limited range. This prevents damage to the intermediate frames during the relocation of the relocation machine when multiple intermediate frames are being relocated.
[0018] When the displaceable belt conveyor needs to be displaced, the intermediate frame can be allowed to move a small amount relative to the guide rail in the direction along the guide rail or perpendicular to the guide rail. In this way, the intermediate frame is subjected to less stress and is not easily deformed. The intermediate frame does not need to be removed separately when the displaceable belt conveyor is displaced. The displaceable belt conveyor can move multiple intermediate frames of the displaceable belt conveyor as a whole. The operation is fully mechanized and efficient, which shortens the displaceable belt conveyor relocation cycle. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] It should also be noted that the terms "upper" and "lower" indicate the directions or positions shown in the accompanying drawings. Figure 1 The orientation or positional relationship is only for the convenience of describing the present disclosure and simplifying the description, and does not indicate or imply that the device or element must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as a limitation on the present disclosure.
[0036] Figures 1 to 6 The structure of the displacement belt conveyor and its flexible connection assembly according to various embodiments of the present utility model is shown.
[0037] like Figures 1 to 6 As shown, an embodiment of the utility model provides a displaceable belt conveyor, which includes an intermediate frame 2 equipped with rollers 1, the intermediate frame 2 is fixed on the sleepers 3, and the sleepers 3 are set on the guide rails 5 of the displaceable belt conveyor 100 through flexible connection components 4.
[0038] An embodiment of the present utility model provides a flexible connection component 4 for a displaceable belt conveyor, the flexible connection component 4 includes: a track clamping pin 41 rotatably connected to the sleeper 3, the track clamping pin 41 has a protrusion 411; the protrusion 411 is configured to cooperate with the guide rail 5 of the conveyor, so that the sleeper 3 is clamped on the guide rail 5; the track clamping pin 41 is configured to have a gap with the sleeper 3, so that the track clamping pin 41 can achieve a limited angle of rotation relative to the guide rail 5.
[0039] There is a gap between the track clamp pin 41 and the sleeper 3. When the track clamp pin 41 rotates relative to the guide rail 5, it passes through this gap and contacts the sleeper 3, thus achieving a limited degree of rotation. The track clamp pin 41 can rotate through a limited angle, allowing the sleeper 3 to move up and down within a small range relative to the guide rail 5. The intermediate frame 2 is fixed to the sleeper 3, allowing the sleeper 3 to move up and down within a small range relative to the guide rail 5. In other words, the intermediate frame 2 is positioned on the guide rail 5 and allows a small degree of movement relative to the guide rail 5 in a sliding direction perpendicular to the guide rail.
[0040] The intermediate frame is fixed to the sleeper, and the sleeper is limitedly set on the guide rail of the conveyor through the above-mentioned flexible connection component. In other words, the intermediate frame is limitedly set on the guide rail of the conveyor through the sleeper; in this way, through the flexible connection component 4 connected to the guide rail by the sleeper, the intermediate frame 2 can achieve a flexible connection relative to the guide rail 5 in the sliding direction perpendicular to the guide rail.
[0041] In one embodiment, the flexible connection assembly 4 includes a rail clamping pin 41 and opposite clamping plates 42 fixed on the sleeper 3 ; the rail clamping pin 41 is clamped between the opposite clamping plates 42 and is rotatably connected to the clamping plates 42 .
[0042] In one embodiment, the track clamp pin 41 has a through-hole 413, and the opposing clamp plate 42 also has a through-hole. A bolt 43 passes through the through-holes of the track clamp pin and the opposing clamp plate, connects the track clamp pin and the opposing clamp plate via a nut, and is secured with a nut 44. The through-hole 413 of the track clamp pin 41 is spaced apart from the long rod of the bolt 43, and the track clamp pin 41 rotates relative to the long rod of the bolt 43. The bolt and nut achieve a detachable connection between the track clamp pin 41 and the opposing clamp plate 42.
[0043] In one embodiment, the rail clamp pin 41 has an end surface 412 on a side close to the sleeper 3 , with a gap 412 a between the end surface 412 and the sleeper. The gap 412 a provides a limited rotation space for the rail clamp pin 41 .
[0044] In one embodiment, the rail clamp pin 41 has a protrusion 411 formed on one side facing the guide rail 5 , and the protrusion 411 and the sleeper 3 form a gap 411a , and the gap 411a is at least embedded with part of the components of the guide rail 5 , so that the sleeper 3 is clamped on the guide rail 5 .
[0045] In one embodiment, Figure 5 As shown, the track clamping pins 41 are a pair, which are respectively arranged on both sides of the guide rail 5.
[0046] The embodiment of the present application provides a displaceable belt conveyor including the above-mentioned flexible connection component 4, which also includes: an intermediate frame 2 equipped with rollers 1 and a guide rail 5, the intermediate frame 2 is fixedly set on the sleeper 3, and the sleeper 3 is set on the guide rail 5 through the flexible connection component 4.
[0047] In one embodiment, Figure 4 As shown, two limiters 6 are also fixed to the guide rail 5, located on either side of the sleeper 3. The intermediate frame 2 is mounted on the guide rail 5 via the sleeper 3. Thus, the two limiters 6 on either side of the sleeper 3 limit the movement of the intermediate frame 2 along the guide rail 5. This allows for limited movement of the intermediate frame 2 along the guide rail 5. The number of limiters 6 may be greater than two, and this is not a limitation here.
[0048] In one embodiment, one end of the limiting device 6 is fixed on the guide rail 5 of the displacement belt conveyor, and the other end of the limiting device 6 extends downward from the guide rail 5 and forms a blocking portion, which limits the sliding of the sleeper 3 along the guide rail.
[0049] In one embodiment, the limiting device 6 is composed of a pair of limiting members 61. One side of each limiting member 61 has a groove 611 that engages with the guide rail 5. The other side of each limiting member 61 protrudes from the guide rail 5 and is secured to the opposing limiting member 61 via a bolt 62 and a nut 63. In this way, the limiting device 6 is detachably secured to the guide rail 5. The two limiting members 61 are oppositely engaged with the guide rail 5 and suspended therefrom.
[0050] In one embodiment, Figure 6 As shown, the guide rail 5 is an I-shaped steel structure having a guide rail base 51 and a guide rail end 52. Ribs extend between the guide rail base and the guide rail end 52. The cross-sectional width of the guide rail base 51 is greater than that of the guide rail end 52. The groove 611 of the limiting member 61 engages with the guide rail base 51. This provides a relatively stable structure for the guide rail 5.
[0051] In one embodiment, a connecting clamp 7 is further provided on the guide rail 5. Since the guide rail 5 is arranged in sections, the connecting clamp 7 fixes adjacent guide rails 5 by bolts and nuts.
[0052] like Figure 6 As shown, the connecting clamp 7 abuts between the guide rail base 51 and the guide rail end 52 of the guide rail 5. The position where the connecting clamp 7 abuts the guide rail end 52 is the first contact area 71, and the position where the connecting clamp 7 abuts the guide rail end 52 is the third contact area 73. In addition, the connecting clamps 7 on both sides of the guide rail 5 are respectively pressed against the ribs of the guide rail 5 by multiple bolts and nuts. Figure 6The two adjacent guide rails 5 are fixed in a position in the direction perpendicular to the paper as shown. The connecting clamp 7 has a second contact area 72 with the ribs of the guide rail 5. The area between the first contact area 71 and the second contact area 72 of the connecting clamp 7 and the guide rail 5 has a gap, so that the connecting clamp 7 can elastically contact the guide rail end 52 in the first contact area 71 by utilizing the elastic stress of the connecting clamp 7. The area between the second contact area 72 and the third contact area 73 of the connecting clamp 7 and the guide rail 5 has a gap, so that the connecting clamp 7 can elastically contact the guide rail base 51 in the third contact area 73 by utilizing the elastic stress of the connecting clamp 7. The connecting clamp 7 elastically contacts the guide rail 51 in the first contact area 71 and the third contact area 73 respectively. Figure 6 The upper and lower positions shown in the figure (or, in other words, the position from the guide rail base 51 to the guide rail end 52) connect adjacent guide rails 51. In other words, if adjacent guide rails 51 have the same specifications, the connecting clamps 7 align the guide rail bases and, similarly, the guide rail ends. The connecting clamps 7 provide a stable connection between adjacent guide rails 51. When the relocatable belt conveyor needs to be relocated, the adjacent guide rails 51 do not move relative to each other, thus preventing interference with the limiting members 61 engaged with the guide rail bases 51.
[0053] In the embodiment, the flexible connection assembly 4 is arranged on the sleeper 3 via a lining plate 8. The lining plate 8 is fixed to the sleeper 3 in a detachable manner, so that the lining plate 8 protects the sleeper 3. At the same time, the lining plate 8 is replaceable if it is worn or damaged.
[0054] When the displaceable belt conveyor needs to be displaced, the intermediate frame can be allowed to move a small amount relative to the guide rail in the direction along the guide rail or perpendicular to the guide rail. In this way, the intermediate frame is subjected to less stress and is not easily deformed. The intermediate frame does not need to be removed separately when the displaceable belt conveyor is displaced. The displaceable belt conveyor can move multiple intermediate frames of the displaceable belt conveyor as a whole. The operation is fully mechanized and efficient, which shortens the displaceable belt conveyor relocation cycle.
[0055] The technical scope of the present invention is not limited to the contents of the above description. Those skilled in the art can make various deformations and modifications to the above implementation without departing from the technical concept of the present invention, and these deformations and modifications should all fall within the scope of the present invention.
