Embodiment 1

Referring to FIGs. 1 to 2, this embodiment provides a circular stacker reclaimer scraper anti-collision limiting device, comprising: a support mechanism 100, including a scraper reclaiming machine 101, which consists of rails, chains, and scraper located between two cantilever frames 102, used for reclaiming materials from a material pile.

The scraper reclaiming machine 101 rotates around the central column in a circular steel structure stockpile shed and is supported by the cantilever frame 102 on both sides, which supports and secures the components of the scraper reclaiming machine

101; a feedback mechanism 200, including an adjustment component 201 set on the 7905623 cantilever frame 102, a fixed plate 202 set on the adjustment component 201, a travel switch A 203 set in the middle of the fixed plate 202, and a feeding component 204 set on the fixed plate 202 and matching the travel switch A 203. The adjustment component 201 can adjust the distance between the fixed plate 202 and the travel switch A 203 from the cantilever frame 102. When the hanging mechanism 300 is compressed, the feeding component 204 is also compressed, thereby pressing the head of the travel switch A 203. The control circuit, in coordination with the travel switch A 203, responds, thereby stopping the rotation of the support mechanism 100, ensuring the integrity of the scraper reclaiming machine 101 and the two side cantilever frames 102; and an hanging mechanism 300, connected to the feeding component 204, including a cross seat 301, a beam 302 set on the cross seat 301, and a force-releasing component 303 set between the cross seat 301 and the beam 302.

When the hanging mechanism 300 is compressed, the feeding component 204 is also compressed.

Operation process: During use, the support mechanism 100 rotates around the central column of the existing circular steel structure stacking shed. When the external hanging mechanism 300 collides with the material pile, the feedback mechanism 200 responds. The travel switch A 203 is pressed, triggering a control circuit that stops the rotation of the support mechanism 100. This ensures the integrity of the scraper reclaiming machine 101 and the cantilever frames 102 on both sides, providing protection for the scraper in the machine. Importantly, the travel switch A 203 is less affected by coal dust and less prone to misoperation.

Embodiment 2

Referring to FIGs. 1 to 4, this embodiment is different from the first embodiment in that: the adjustment component 201 includes a screw 201a set on the side of the cantilever frame 102, a driven umbrella gear 201b and an inner threaded sleeve 201c successively sleeved outside the screw 201a, two telescopic columns A 201d symmetrically set outside the inner threaded sleeve 201c, and a drive and rotation 7905623 component 201e set on the side of the cantilever frame 102; a bearing seat 201f is set on the side of the cantilever frame 102, and a ball bearing is arranged inside the bearing seat 201f; the screw 201a is rotatably set inside the ball bearing; the outer wall of the end of the screw 201a is fixedly connected to the inner ring of the ball bearing by a key connection method; wherein, the driven umbrella gear 201b is fixedly socketed outside the screw 201a, the screw 201a is inserted and threadedly connected inside the inner threaded sleeve 201c, and the fixed plate 202 is fixedly connected to one end away from the cantilever frame 102 of the inner threaded sleeve 201c; in this way, by adjusting the rotation direction of the screw 201a, the fixed plate 202, travel switch A 203, feeding component 204, and the horizontal translation of the hanging mechanism 300 connected to the feeding component 204 can be driven, thereby adjusting the detectable distance of the device, adjusting the collision response rate of the device, and improving the adaptability of the device in different usage scenarios.

The telescopic columns A 201d at both ends are connected to the cantilever frame 102 and the fixed plate 202, respectively. The telescopic columns A 201d are used to support the horizontal translation of the fixed plate 202 outside the cantilever frame 102, ensuring the stability of the translation of the fixed plate 202 and reducing the possibility of tipping. The drive and rotation component 201e is matched with the driven umbrella gear 201b, and the drive and rotation component 201e is used to drive the driven umbrella gear 201b, thereby achieving the purpose of driving the rotation of the screw 201a.

Specifically, the drive and rotation component 201e includes a motor support frame 201e-1, a servo motor 201e-2 set inside the motor support frame 201e-1, and an active umbrella gear 201e-3 set on the output end of the servo motor 201e-2. The motor support frame 201e-1 is fixedly mounted on the cantilever frame 102, and the servo motor 201e-2, when started, can drive the active umbrella gear 201e-3 on its output end to rotate. The characteristics of the servo motor 201e-2 allow the active umbrella gear 201e-3 to switch between positive and negative rotation states flexibly;

the active umbrella gear 201e-3 is meshed and connected with the driven umbrella 7905623 gear 201b, and the active umbrella gear 201e-3 driven by the output end of the servo motor 201e-2 can mesh and drive the driven umbrella gear 201b to rotate. It is common mechanical knowledge and will not be further elaborated.

Furthermore, the feeding component 204 includes two symmetrical limiting frames 204a, telescopic column B 204b set on the limiting frames 204a, pile top 204c set on the cross seat 301, abutment block 204d set on the pile top 204c, and elastic components 204e set in two limiting frames 204a, respectively. Telescopic column B 204b is used to limit the movement of the cross seat 301, avoid skewing and tipping of the hanging mechanism 300 after being pressed by the material pile, pile top 204c and abutment block 204d are integrally formed to ensure structural strength and reliability, and avoid deformation. The limiting frame 204a is mounted on the fixed plate 202, and the elastic components 204e are all connected to the abutment block 204d. The elastic components 204e are used to achieve the away-from travel switch A 203 of the feeding component 204 when the hanging mechanism 300 is not under pressure, avoiding the pressing of the travel switch A 203 and preventing frequent misoperation of the main limiting switch in the device. The elastic components 204e include limiting column 204e-1 set inside the limiting frame 204a and spring A 204e-2 set on the limiting column 204e-1. The side of the limiting frame 204a is pierced with a through opening 204a-1, and the limiting column 204e-1 is slidably inserted into the through opening 204a-1, and the spring A 204e-2 is set inside the through opening 204a-1. The limiting column 204e-1, under the elastic action of the spring A 204e-2, can drive the abutment block 204d and the pile top 204c to move towards the side away from the cantilever frame 102, achieving the outward extension reset of the hanging mechanism 300 under pressure, facilitating the hanging mechanism 300 to be once again placed into the normal working position.

The remaining structures are the same as in the Embodiment 1.

Operational process: During use, start the servo motor 201e-2. The output end of 7905623 the servo motor 201e-2 can drive the active umbrella gear 201e-3 to rotate. The rotation of the active umbrella gear 201e-3 can mesh and drive the driven umbrella gear 201b to rotate. The rotation of the driven umbrella gear 201b can drive the screw 201a inside it to rotate. By switching the positive and negative directions of the output end of the servo motor 201e-2, the cantilever frame 102, fixed plate 202, and feeding component 204, and even the horizontal translation of the hanging mechanism 300 connected to the feeding component 204, can be achieved. Thus, the detectable distance of the device can be adjusted, and the collision response rate of the device can be adjusted. After the hanging mechanism 300 collides with the material pile, the pile top 204c and the abutment block 204d in the feeding component 204 can move towards the side close to the cantilever frame 102 under the cooperation of the elastic component 204e, causing the abutment block 204d to press the head of the travel switch A 203, resulting in the stoppage of the support mechanism 100. On the contrary, when the hanging mechanism 300 leaves the material pile, the limiting column 204e- 1, under the elastic action of the spring À 204e-2, can drive the abutment block 204d and the pile top 204c to move towards the side away from the cantilever frame 102, achieving the outward extension reset of the hanging mechanism 300 under pressure.

This facilitates the hanging mechanism 300 to be once again placed into the normal working position.

Embodiment 3

Referring to FIGs. 1 and 4-7, this embodiment differs from the previous embodiments in that the force-releasing component 303 includes symmetrically set telescopic columns C303a, fixed rings 303b set on the side of the cross seat 301, two arc openings 303c opened on the fixed rings 303b, two pin columns 303d set in the fixed rings 303b, supporting plates 303e sleeved outside the two pin columns, plates 303f set inside the two arc openings, springs B303g set between the plates and the supporting plates, and a telescopic component 303h set inside the fixed ring 303b. The side of the cross seat 301 is centrally provided with an installation groove for embedding the fixed ring 303b, and the pin columns 303d can be placed through the 7905623 symmetrically set rotating brackets on the fixed ring 303b. The supporting plates 303e have a V-shaped structure; the supporting plates 303e are rotatably connected outside the pin columns 303d, and the plates 303f cooperate with the springs B303g to, after the retraction of the telescopic component 303h, use the lever principle to spread the outer convex ends of the two supporting plates 303e to both sides. This allows for the recovery of the beam 302 pressed by the material pile towards one side of the cross seat 301, i.e., force relief. This prevents the deformation and damage of the beam 302 in the external hanging mechanism 300 after prolonged compression, improving the service life and usage cycle of the external hanging mechanism 300. The two telescopic columns C303a are connected at both ends to the cross seat 301 and the beam 302, respectively. The telescopic columns C303a are used to link the cross seat 301 and the beam 302, combining them into a single unit. The two supporting plates 303e are movably set inside the two arc openings 303c, and the supporting plates 303e can rotate around the axis of the corresponding pin columns 303d. The telescopic component 303h matches with the two supporting plates 303e, and the telescopic component 303h, through deformation, can drive the two supporting plates 303e to perform reciprocating movements.

Specifically, the telescopic component 303h includes an installation base 303h-1 set inside the fixed ring 303b, an air cushion 303h-2 set on the installation base 303h- 1, and air inlet and outlet pipes 303h-3 and 303h-4 set on the side of the air cushion.

The air inlet and outlet pipes 303h-3 and 303h-4 are used to achieve inflation and deflation of the air cushion 303h-2; the installation base 303h-1 is mounted on the inner wall of the fixed ring 303b away from the cross seat 301, and the air cushion 303h-2 is fixedly mounted on the installation base 303h-1. To avoid the poor supporting effect of the air cushion 303h-2 on the two supporting plates 303e, a stainless steel expansion joint can be provided outside the air cushion 303h-2 to ensure that the end of the air cushion 303h-2 maintains a relatively balanced supporting effect on the supporting plates 303e, avoiding uneven force on the two supporting plates 303e as much as possible and ensuring the synchronous rotation of 7905623 the two supporting plates 303e. The telescopic component 303h also includes a release component 303h-5, which includes an electromagnetic valve 303h-5a set on the outlet pipe 303h-4 and a miniature air pump 303h-5b set on the inlet pipe 303h-3.

When the electromagnetic valve 303h-5a on the outlet pipe 303h-4 is opened, the gas in the air cushion 303h-2 is rapidly released under the pressure effect of the two springs B303g and the two supporting plates 303e. Conversely, when the electromagnetic valve 303h-5a is closed, the outlet pipe 303h-4 is sealed, and air can be pumped into the inlet pipe 303h-3 by pumping air into the miniature air pump 303h-5b, thereby achieving the purpose of inflating the air cushion 303h-2. There is also a miniature air pump 303h-5c installed on the cross seat 301, connected to the miniature air pump 303h-5b. Its start and stop can switch between pumping air into the miniature air pump 303h-5b and stopping air supply.

Furthermore, the side of the limiting frame 204a is set with a travel switch B303i.

After the abutment block 204d presses against the head of the travel switch A203, stopping the rotation of the scraper reclaiming machine 101, the class T-shaped limiting column 204e-1, connected with the abutment block 204d, can sequentially realize pressing against the head of the travel switch B303i. In coordination with the travel switch B303i, the control circuit responds, opening the electromagnetic valve 303h-5a to quickly outlet the air cushion 303h-2. This promotes the recovery of the beam 302 pressed by the material pile towards one side of the cross seat 301, achieving force relief. Conversely, when the external hanging mechanism 300 retracts and returns to subsequent operations, the abutment block 204d and the pile top 204c move towards the side away from the cantilever frame 102. The class T-shaped limiting column 204e-1 also moves with them, and the head of the travel switch B303i is no longer pressed. The external hanging mechanism 300 is released, and in coordination with the travel switch B303i, the control circuit continues to respond, closing the electromagnetic valve 303h-5a. After that, the miniature air pump 303h-5c is started to pump air into the air cushion 303h-2 until it is full, and the miniature air pump 303h-

5c stops. In this way, after the retraction and resetting of the external hanging 7905623 mechanism 300, the beam 302 in the external hanging mechanism 300 is also reset, making it convenient for the subsequent use of the force relief effect after compression.

The electrical connection between the travel switch B303i and the electromagnetic valve 303h-5a, as well as the miniature air pump 303h-5c, is understood.

The remaining structures are the same as in Embodiment 2.

Operation process: During use, when the hanging mechanism 300, rotating with the support mechanism 100, collides with the material pile, after the abutment block 204d presses against the head of the travel switch A203, the scraper reclaiming machine 101 stops rotating. The class T-shaped structure of the abutment column 204e-1, connected to the abutment block 204d, can smoothly press against the head of the travel switch B303i. This action opens the electromagnetic valve 303h-5a, rapidly outleting the air from the air cushion 303h-2. Utilizing the lever principle, the outer convex ends of the two supporting plates 303e expand to both sides. This action can exert a force on the beam 302, which is pressed by the material pile, causing it to retract to one side of the cross seat 301. This achieves the purpose of unloading, thereby avoiding deformation and damage to the beam 302 in the hanging mechanism 300 subjected to prolonged pressure.
