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 referred to 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.
[0023] Figures 1 to 6 The structures of the displacement belt conveyor and the flexible connection components thereof according to various embodiments of the present invention are shown.
[0024] like Figures 1 to 6 As shown, an embodiment of the present invention provides a displaceable belt conveyor, which includes an intermediate frame 2 equipped with rollers 1, the intermediate frame 2 is fixed on sleepers 3, and the sleepers 3 are arranged on the guide rails 5 of the displaceable belt conveyor 100 through flexible connection components 4.
[0025] An embodiment of the present invention provides a flexible connection assembly 4 for a displaceable belt conveyor, the flexible connection assembly 4 comprising: a track clamp pin 41 rotatably connected to a sleeper 3, the track clamp pin 41 having a protrusion 411; the protrusion 411 is configured to cooperate with a guide rail 5 of the conveyor, so that the sleeper 3 is clamped on the guide rail 5; the track clamp pin 41 is configured to have a gap with the sleeper 3, so that the track clamp pin 41 can achieve a limited angle of rotation relative to the guide rail 5.
[0026] 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, the track clamp pin 41 passes through the gap and contacts the sleeper 3, thus realizing a limited angle of rotation. The track clamp pin 41 can rotate at a limited angle, and the sleeper 3 is allowed to move up and down in a small range relative to the guide rail 5. The intermediate frame 2 is fixed on the sleeper 3, and the sleeper 3 is allowed to move up and down in a small range relative to the guide rail 5, that is, the intermediate frame 2 is clamped on the guide rail 5, and is allowed to move in a small range relative to the guide rail 5 in a sliding direction perpendicular to the guide rail.
[0027] The intermediate frame is fixed to the sleepers, and the sleepers are set on the guide rails of the conveyor in a limited position through the above-mentioned flexible connection components. In other words, the intermediate frame is set on the guide rails of the conveyor in a limited position through the sleepers; in this way, through the flexible connection components 4 connected to the guide rails through the sleepers, the intermediate frame 2 can achieve a flexible connection relative to the guide rails 5 in a sliding direction perpendicular to the guide rails.
[0028] In one embodiment, the flexible connection assembly 4 includes a rail clamp pin 41 and opposite clamping plates 42 fixed on the sleeper 3 ; the rail clamp pin 41 is clamped between the opposite clamping plates 42 and is rotatably connected to the clamping plates 42 .
[0029] In one embodiment, the track clamp pin 41 has a through hole 413, and the opposite clamp plate 42 also has a through hole. The bolt 43 passes through the through holes of the track clamp pin and the opposite clamp plate, connects the track clamp pin and the opposite clamp plate through a nut, and is fixed with a nut 44. The through hole 413 of the track clamp pin 41 has a gap with the long rod of the bolt 43, and rotates relative to the long rod of the bolt 43. The track clamp pin 41 and the opposite clamp plate 42 are detachably connected by the bolt and nut.
[0030] In one embodiment, the track clamp pin 41 has an end surface 412 on a side close to the sleeper 3 , and a gap 412 a is formed between the end surface 412 and the sleeper, and the gap 412 a provides a limited rotation space for the track clamp pin 41 .
[0031] 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 partially embedded with the components of the guide rail 5 , so that the sleeper 3 is clamped on the guide rail 5 .
[0032] In one embodiment, Figure 5 As shown, the track clamp pins 41 are a pair, which are respectively arranged on both sides of the guide rail 5.
[0033] A displaceable belt conveyor including the above-mentioned flexible connection component 4 provided in an embodiment of the present application also includes: an intermediate frame 2 and a guide rail 5 on which rollers 1 are installed, 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.
[0034] In one embodiment, Figure 4 As shown, two limit devices 6 are also fixed on the guide rail 5, and the two limit devices are located on both sides of the sleeper 3. The intermediate frame 2 is set on the guide rail 5 through the sleeper 3, so that the two limit devices 6 on both sides of the sleeper 3 can limit the movement displacement of the intermediate frame 2 on the guide rail 5 along the guide rail direction. In this way, the intermediate frame 2 can be allowed to move limitedly on the guide rail 5 along the guide rail direction. The number of limit devices 6 can also be greater than two, which is not limited here.
[0035] 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 direction.
[0036] 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 engaged with the guide rail 5, and the other side is suspended from the guide rail 5 and fixed to the other opposite limiting member 61 by a bolt 62 and a nut 63. In this way, the limiting device 6 is detachably fixed to the guide rail 5. The two limiting members 61 are relatively buckled on the guide rail 5 and suspended on the guide rail 5.
[0037] In one embodiment, Figure 6 As shown, the guide rail 5 is an I-shaped steel, having a guide rail base 51 and a guide rail end 52, and a rib extends between the guide rail base and the guide rail end 52. The cross-sectional width of the guide rail base 51 is greater than the cross-sectional width of the guide rail end 52, and the groove 611 of the limiting member 61 is engaged with the guide rail base 51. Such a guide rail 5 provides a relatively stable structure. 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 the adjacent guide rails 5 by bolts and nuts.
[0038] 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 against the guide rail end 52 is the first contact area 71, and the position where the connecting clamp 7 abuts against 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 a plurality of bolts and nuts. Figure 6 The two adjacent guide rails 5 are fixed in a position in the direction perpendicular to the paper plane 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 has a gap with the guide rail 5, so that the connecting clamp 7 can elastically abut against 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 has a gap with the guide rail 5, so that the connecting clamp 7 can elastically abut against 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 abuts against the guide rail 51 in the first contact area 71 and the third contact area 73, respectively. Figure 6The upper and lower directions (or the directions from the guide rail base 51 to the guide rail end 52) shown in the figure limit the connection of the adjacent guide rails 51. In other words, if the specifications of the adjacent guide rails 51 are the same, the guide rail bases of the adjacent guide rails 51 are aligned through the connecting clamp 7, and similarly, the guide rail ends are also aligned. The connecting clamp 7 provides a stable connection method for the adjacent guide rails 51. When the displaceable belt conveyor needs to be displaced, the adjacent guide rails 51 will not produce relative movement, so that the limiting member 61 engaged on the guide rail base 51 will not be interfered.
[0039] In the embodiment, the flexible connection assembly 4 is arranged on the sleeper 3 through the lining plate 8. The lining plate 8 is fixed on the sleeper 3 when it is detachable, 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.
[0040] 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 along the guide rail direction or perpendicular to the guide rail direction. 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 machine can move multiple intermediate frames of the displaceable belt conveyor as a whole. The operation is fully mechanized, efficient, and shortens the displacement period of the displaceable belt conveyor.
[0041] 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 idea of the present invention, and these deformations and modifications should all fall within the scope of the present invention.
