Refer to Fig. 1, Fig. 1 is the structural representation of the fault-belt catching device in the utility model specific embodiment scheme.
In a kind of specific embodiment scheme, the utility model provides a kind of fault-belt catching device of belt conveyer, comprise for the carrying roller guide rail 11 for roller carrier shaft 10 anterior-posterior translation, for supporting plate 3 and the elastic clamp device of bearing conveying belt side, carrying roller guide rail 11 is provided with the limiting stopper of restriction roller carrier shaft 10 displacement, supporting plate 3 follows roller carrier shaft 10 together along carrying roller guide rail 11 translation by baffle plate 2, elastic clamp device comprises pressing plate 4 and the Flexible clamp for pressing plate 4 to be pressed in supporting plate 3 together with belt edge, supporting plate 3 is connected with the application force for overcoming Flexible clamp and pressing plate 4 and supporting plate 3 is strutted the movable rod 5 of predeterminable range, when roller carrier shaft 10 backward translation time movable rod 5 cancel application force to Flexible clamp.
It should be noted that described " backward translation " and " retrogressing ", " moving afterwards " etc. specifically refer to herein to move in the opposite direction along with tape transport material side.
Concrete, carrying roller guide rail 11 is for supporting carrier roller 1, and the roller carrier shaft 10 of carrying roller 1 to be disposed across on two carrying roller guide rails 11 and can along the translation of carrying roller guide rail 11 slide anteroposterior.Limiting stopper is positioned at the front end of carrying roller guide rail 11, and for roller carrier shaft 10 is limited to limiting stopper position, roller carrier shaft 10 drives carrying roller 1 to rotate under the driving of drive system, thus can drag load-transfer device and carry out mass transport.Supporting plate 3 is for the side of bearing conveying belt, and when ruptured belt, supporting plate 3 provides lower support face for clamping conveying belt.Supporting plate 3 is interacted by baffle plate 2 and roller carrier shaft 10, concrete, and baffle plate 2 for clamping group prong like of roller carrier shaft 10, can promote baffle plate 2 together translation, supporting plate 3 so just can be driven together to move when roller carrier shaft 10 carries out slide anteroposterior translation.Elastic clamp device is used to clamp fracture load-transfer device, and it specifically utilizes Flexible clamp to the elastic acting force of pressing plate 4 to realize the pinching action of pressing plate 4.In conveyer normal course of operation, due to the invariant position of roller carrier shaft 10, the movable rod 5 be connected with supporting plate 3 will keep the application force to Flexible clamp, and pressing plate 4 and supporting plate 3 are strutted predeterminable range, elastic clamp device would not carry out pinching action to load-transfer device, to ensure the impact of load-transfer device not compression plate 4 and supporting plate 3, thus realize normally carrying operation.When roller carrier shaft 10 drives supporting plate 3 to move backward, now, movable rod 5 just can cancel the application force to Flexible clamp, and pressing plate 4 is just pressed on the top of supporting plate 3 and load-transfer device by elastic clamp device immediately after obtaining release.
It should be noted that, carrying roller 1 in this programme can adopt One-way cradle roll, setting like this, when there is fracture in load-transfer device, load-transfer device slides backward, and One-way cradle roll then can not rotate round about, but can by the backward rear generation sliding translation of friction force of load-transfer device, employing One-way cradle roll can increase the friction force between load-transfer device and carrying roller 1, thus carrying roller 1 can be driven fast to slide backward translation.Meanwhile, in order to the friction force moving past in journey after reducing roller carrier shaft 10 and between carrying roller guide rail 11, preferably, this programme is provided with roller between roller carrier shaft 10 and carrying roller guide rail 11, due to the rolling support of roller, greatly can reduce friction, move past Cheng Gengjia after making roller carrier shaft 10 fast, steadily.
It should be noted that, supporting plate 3 is supported in conveyer bearing 9 by pallet guide, thus can provide failure-free bearing force for load-transfer device.Preferably, pallet guide is provided with the webge slot 8 raised gradually along roller carrier shaft 10 direction of retreat, and supporting plate 3 is connected to this webge slot 8 by wedge slides.Concrete, because the bearing surface of supporting plate 3 and the angle of horizontal surface remain unchanged, the bottom land of webge slot 8 raises gradually along roller carrier shaft 10 direction of retreat, therefore, just defines the webge slot 8 that sectional elevation is wedge shape.The voussoir of supporting plate 3 interts in webge slot 8, when supporting plate 3 backward translation time, voussoir is subject to the supporting role of webge slot 8 bottom land, therefore, make voussoir together with supporting plate 3 upwards lifting, setting like this, when ruptured belt, load-transfer device is clamped by pressing plate 4 and supporting plate 3, and supporting plate 3 after move past in journey and also rise gradually, just reduce the gap between supporting plate 3 and pressing plate 4, thus load-transfer device can be held tighter, improve the reliability of this fixing device.When moving on to the extreme end of webge slot 8 after voussoir, supporting plate 3, pressing plate 4 and load-transfer device three are tightly closed together, and the sliding force of retrogressing is larger, and arresting of pressing plate 4 and supporting plate 3 pairs of load-transfer devices is more firm.Preferably, in order to ensure that pressing plate 4 and supporting plate 3 can clamping conveying belts securely, simultaneously in order to avoid causing excessive damage to load-transfer device, the minimum clearance in this programme between supporting plate 3 and pressing plate 4 is the half of load-transfer device thickness.
It should be noted that, the elastic clamp device in this programme can have various structures form, and such as pressing plate 4 along the direction clamping of the bearing surface perpendicular to supporting plate 3 or can unclamp, and Flexible clamp then controls pressing plate 4 and linearly moves; Or pressing plate 4 along the circumferential direction can rotate the top to supporting plate 3, Flexible clamp then controls pressing plate 4 and along the circumferential direction moves; Or pressing plate 4 moves on to the top of supporting plate 3 along the direction of the bearing surface being parallel to supporting plate 3, Flexible clamp then controls pressing plate 4 and linearly moves etc.Preferably, the pressing plate 4 in this programme have employed the mode of motion rotating and move on to above supporting plate 3, and namely pressing plate 4 is articulated with conveyer bearing by axis of revolution 7, and Flexible clamp then drives pressing plate 4 to turn to above supporting plate 3.Concrete, because the position of pressing plate 4 is higher, pressing plate 4 is articulated with fastening frame 6, and fastening frame 6 is fixed on conveyer bearing 9, thus it is hinged fixing to achieve between pressing plate 4 and conveyer bearing 9.
And realize the mode that pressing plate 4 rotates and also have multiple, such as pressing plate 4 can rotary motion in perpendicular, and when needs clamping conveying belt, pressing plate 4 rotates above supporting plate 3; Pressing plate 4 can also move in the trajectory plane that edge is parallel to the bearing surface of supporting plate 3; Or angle etc. can also be there is with the bearing surface of supporting plate 3 in the rotary motion trace plane of pressing plate 4.It can thus be appreciated that the layout of the selection trajectory plane of pressing plate 4 is determined by the arrangement of the axis of revolution 7 between pressing plate 4 and fastening frame 6, namely axis of revolution 7 put the rotation direction directly determining pressing plate 4.Preferably, the rotary motion trace plane parallel of the pressing plate 4 in this programme is in the bearing surface of supporting plate 3, setting like this, in the process of pressing plate 4 and supporting plate 3 clamping conveying belt, can ensure that biside plate and load-transfer device remain Maximum Contact area, thus enough friction force can be ensured, and then load-transfer device is stopped gliding as early as possible.

Preferably, movable rod 5 in this programme specifically comprises the drive spindle being fixed on supporting plate 3 and the postive stop baffle being articulated with conveyer bearing 9, in conveyer normal course of operation, postive stop baffle rotates the side to pressing plate 4 thus stops pressing plate 4 to turn to above supporting plate 3, drive spindle then provides support power for postive stop baffle, and when namely supporting plate 3 keeps static, postive stop baffle is just fixed on the position stopping pressing plate 4 by drive spindle; When supporting plate 3 backward translation time drive spindle also move afterwards together, at this moment, drive spindle then cancels the bearing force to postive stop baffle, and therefore postive stop baffle rotates to departing from the position of pressing plate 4, and finally, the elastic acting force of Flexible clamp just drives pressing plate 4 to turn to the top of supporting plate 3.
When load-transfer device normally runs, pressing plate 4 can not affect the advance conveying motion of load-transfer device, therefore, movable rod 5 needs predeterminable range pressing plate 4 and supporting plate 3 being strutted certain safety, and preferably, in this programme, the minimum value of predeterminable range is 1.3 times of load-transfer device thickness, setting like this, load-transfer device just can have sufficient space to run, and can not rub, also ensure that operating efficiency in operational process with pressing plate 4.
Fixing in order to make more fast, more safely to arrest load-transfer device during ruptured belt, preferably, this programme is provided with supporting plate 3 and elastic clamp device in the both sides of load-transfer device, setting like this, when ruptured belt, the supporting plate 3 of both sides and elastic clamp device just promptly can fix load-transfer device, can ensure that load-transfer device is unlikely to sideslip simultaneously, be conducive to follow-up maintenance work.
It should be noted that, the fault-belt catching device that this programme provides is applicable to the belt conveyer with inclination angle, also goes for belt conveyer not with angle.
When conveyer normal operation, roller carrier shaft 10 is positioned at the limiting stopper place of carrying roller guide rail 11, carrying roller 1 is positioned at immediately below load-transfer device, the side of load-transfer device is positioned on supporting plate 3, because pressing plate 4 and supporting plate 3 are strutted certain predeterminable range by movable rod 5, therefore, load-transfer device can smoothly by between supporting plate 3 and pressing plate 4.When load-transfer device ruptures suddenly, owing to being subject to the Action of Gravity Field of material, load-transfer device can landing backward.Carrying roller 1 together translation backward by the squeezing action of load-transfer device, roller carrier shaft 10 drives supporting plate 3 together to move afterwards by baffle plate 2, now, movable rod 5 cancels the application force to Flexible clamp, Flexible clamp just drives pressing plate 4 to be pressed in above supporting plate 3 and belt edge tightly, thus load-transfer device is fixed, prevent post-rift load-transfer device from gliding further.
