[0035] The centering support 10 mechanism includes a plurality of longitudinally spaced centering supports 10, the top of the centering support 10 is used for connecting the belt 50, and the bottom of the centering support 10 is rotatably connected to the rack;The winch 40 is fixed on the rack, and the winch 40 is longitudinally spaced from one end of the centering support 10, and the steel wire rope 410 of the winch 40 is connected to the two ends of the centering support 10 along the transverse direction;The side of the centering support 10 close to the winch 40 is connected with the bump bar assembly 20, the travel switch assembly 30 and the bump bar assembly 20 are longitudinally spaced, and the movement path of the bump bar assembly 20 and the travel switch assembly 30 have a limit intersection point.

[0036] Specifically, the deviation adjusting device of the boom belt 50 of the bucket wheel stacker-reclaimer in the application comprises a rack, a self-aligning support 10 mechanism, a collision rod assembly 20, a travel switch assembly 30 and a winch 40, the rack (not shown in the figure) is used for mounting and connecting the self-aligning support 10 mechanism, the travel switch assembly 30 and the winch 40; the self-aligning support 10 mechanism is used for mounting and connecting the belt 50, which comprises a plurality of self-aligning supports 10 arranged at intervals in the longitudinal direction to meet the requirement that the belt 50 is supported by the self-aligning support 10 at intervals, each two adjacent self-aligning supports 10 are arranged at intervals of 10 m, and the deviation of the belt 50 needs to be corrected by adjusting the deviation angle of the self-aligning support 10 mechanism, so the bottom of the self-aligning support 10 needs to be rotatably connected to the rack, and here the rotation means rotation along the horizontal plane (the rotation axis 130 is vertically extended); the travel switch assembly 30 is used for touching the self-aligning support 10 when the belt 50 deviates to drive the self-aligning support 10 to rotate, so as to feed back the deviation signal, therefore, in order to facilitate the touch, the collision rod assembly 20 is additionally arranged on the self-aligning support 10 to touch the travel switch assembly 30, and after the signal is obtained, the winch 40 is used to tighten the self-aligning support 10 to achieve the deviation adjusting effect.

[0037] The winch 40 is fixed to the rack (of the stacker-reclaimer boom), and is arranged at one end of the self-aligning support 10 in the longitudinal direction to facilitate the connection of the steel wire rope 410 and the self-aligning support 10, and it is worth mentioning that the winch 40 needs to be arranged in the middle to facilitate the uniform distribution of the steel wire rope 410 of the winch 40 when the steel wire rope 410 is connected to the two ends of the self-aligning support 10 in the transverse direction, so that the force on the two ends in the transverse direction is uniform when the steel wire rope 410 is tightened, thereby ensuring better deviation adjusting effect, and preferably, a link cabinet can be additionally arranged between the winch 40 and the self-aligning support 10 to serve as an assembly pulley, thereby facilitating the winding of the steel wire rope 410 on the pulley and the connection of the steel wire rope 410 to the two ends of the self-aligning support 10 in the transverse direction, to achieve the effect of saving labor, please refer to the specific structure in the attached drawings. Figure 4 The collision rod assembly 20 is arranged on one side of the self-aligning support 10 close to the winch 40, based on the principle that the closer to the end, the greater the deviation, so that the deviation adjusting effect at the position with large deviation can ensure the working performance of the entire boom belt 50; the travel switch assembly 30 is arranged at intervals in the longitudinal direction with the collision rod assembly 20, when the collision rod assembly 20 deviates and rotates with the self-aligning support 10, the collision rod assembly 20 needs to touch the travel switch assembly 30 to send the deviation signal, therefore, under the premise of ensuring the interval arrangement, the movement path of the collision rod assembly 20 needs to have a limit intersection point with the travel switch assembly 30, thereby ensuring the normal operation of the device.

[0038] It is worth noting that in a preferred embodiment, an electrical control device (electrical control box) can be provided, which includes but is not limited to an AC contactor, which is electrically connected to the hoist 40 and the travel switch assembly 30 through a line, so that the closing and opening of the normally open contact signal of the travel switch assembly 30 controls the attraction of the AC contactor, thereby controlling the operation of the hoist 40, and the normally closed contact in the travel switch assembly 30 is electrically interlocked to ensure that the hoist 40 only has one operating direction. The electrical control is well known, so it is not described in detail here. In this way, the effect of automatic deviation after receiving the feedback of the travel switch assembly 30 is achieved, further improving the efficiency.

[0039] As a preferred embodiment of the utility model, each said aligning support 10 includes a support bracket 110, a roller bracket 120 and a rotating shaft 130, the rotating shaft 130 is vertically arranged and rotatably connected to the rack, the support bracket 110 is fixed to the top end of the rotating shaft 130, the roller bracket 120 is connected to the support bracket 110, the top of the roller bracket 120 is used for connecting the belt 50, and the roller bracket 120 is rotatably arranged.

[0040] It should be noted that the support bracket 110 is used as a support stress point, and the rotating shaft 130 is used to achieve the purpose of rotating deviation, so the rotating shaft 130 is rotatably arranged between the support bracket 110 and the rack. The roller bracket 120 is used for installing the belt 50, and the roller support mode can facilitate the small rolling of the belt 50 when the belt 50 is deviated and rubbed, thereby relieving the damage of the friction force to the structure.

[0041] As a preferred embodiment of the utility model, the support bracket 110 is upwardly inclined at the two ends in the transverse direction.

[0042] It should be noted that since the cantilever belt 50 is usually upwardly inclined at the two ends in the transverse direction in the present application, the support bracket 110 is also upwardly inclined at the two ends in the transverse direction, so as to match the belt 50, thereby facilitating the installation and placement of the belt 50.

[0043] As a preferred embodiment of the utility model, the roller bracket 120 includes a flat roller 121 and two inclined rollers 122 arranged opposite in the transverse direction.

[0044] The support support 110 is provided with inclined supports 111 on the two ends of the horizontal section in the transverse direction, the vertical supports 112 are provided on the two ends of the horizontal section of the support support 110 in the transverse direction, the inclined rollers 122 are rotatably connected between the inclined supports 111 and the vertical supports 112, and the flat rollers 121 are rotatably connected between the two vertical supports 112.

[0045] It is worth noting that the roller support 120 is similar to the support support 110 and also adopts the supporting mode matched with the belt 50, so that the flat roller 121 is used for supporting the horizontal section of the belt 50, and the inclined roller 122 is used for supporting the inclined section of the belt 50, and the inclination angle of the inclined roller 122 can be matched with the inclination section of the belt 50, and is preferably 30°-35°. Meanwhile, the inclined roller 122 also serves as the main force point for the deviation adjustment of the belt 50, and when the belt 50 deviates in the transverse direction, the contact point of the belt 50 with the inclined roller 122 generates extrusion friction force and drives the entire eccentric support to deviate. Therefore, in order to facilitate the installation and connection of the rollers, the vertical supports 112 are provided on the two ends of the horizontal section of the support support 110 in the transverse direction, and the inclined supports 111 are provided on the two ends of the support support 110 in the transverse direction.

[0046] As a preferred embodiment of the utility model, the collision rod assembly 20 comprises a connecting frame 210 and a collision rod 220, the connecting frame 210 is L-shaped, the connecting frame 210 is connected below the inclined section of the support support 110, and the collision rod 220 is fixed to the bottom of the connecting frame 210 and is arranged in the longitudinal direction.

[0047] It is worth noting that the connecting frame 210 is used for mounting the collision rod 220, and is L-shaped, so that the collision rod 220 is extended to a certain position outside, so that the collision rod 220 is in contact with the travel switch assembly 30, and a limiting intersection point is formed during movement.

[0048] Further, the travel switch assembly 30 comprises two travel switches 310 arranged in the longitudinal direction, and the two travel switches 310 are arranged in the longitudinal direction with the collision rod 220.

[0049] It should be noted that since the travel switch assembly 30 is arranged on one side of the alignment support 10 close to the winch 40, two travel switches 310 are arranged to ensure that the travel switch 310 is in contact when the belt 50 deviates in the transverse direction, so as to feed the deviation signal.

[0050] Further, the pull ring 140 is further included, and two ear plates 113 are formed on the lateral wall of each of the inclined supports 111, and the vertical connecting holes are formed on the ear plates 113 for connecting the pull ring 140, one end of the pull ring 140 is hinged between the two ear plates 113, and the other end of the pull ring 140 is provided with a longitudinal through hole, and the steel wire rope 410 of the winch 40 is threaded and wound in the longitudinal through hole.

[0051] It should be understood that the pull ring 140 is used for connecting the steel wire rope 410 of the winch 40, so as to achieve the purpose of tension adjustment, and the two ear plates 113 are formed on the lateral wall of each of the inclined supports 111, and the two ear plates 113 are hinged, so as to avoid the damage to the structure when tensioning and rotating, and the hinged and rotating tensioning mode is more adaptive, and the longitudinal through hole formed on the other end of the pull ring 140 is used for threading and winding the steel wire rope 410 of the winch 40, so as to connect the steel wire rope 410 of the winch 40 with the two ends of the aligning support 10 along the lateral direction.

[0052] Further, the interval distance between the impact rod 220 and the travel switch 310 along the longitudinal direction is 50mm-100mm.

[0053] It should be understood that the interval distance between the impact rod 220 and the travel switch 310 along the longitudinal direction needs to ensure that the impact rod 220 can touch the travel switch 310 when the belt 50 is deviated, and the closer the interval distance is, the smaller the deviation amount is, and the deviation signal can be sent, so that the deviation can be adjusted without affecting the production effect, and the interval distance can be set to 50mm-100mm in the preferred embodiment, and the technical personnel in the field can select according to the needs.

[0054] In order to facilitate the technical personnel in the field to understand, the working process of the present application is briefly described as follows:

[0055] When the cantilever belt 50 is deviated, the roller support 120 is deviated by the friction of the belt 50 to drive the support bracket 110 to rotate synchronously, the impact lever 220 fixed on the support bracket 110 rotates, when the impact lever 220 touches the travel switch 310, the normally open contact in the travel switch 310 (the rotatable impact lever inside is deviated) is closed, at this time the control electrical device (the control electrical box) is closed, the motor drives the winch 40 to rotate, the winch 40 tightens the steel wire rope 410 to drive the whole alignment bracket 10 to deviate, the linear motion direction of the alignment bracket 10 and the transport direction of the belt 50 form an angle, the friction generated drives the belt 50 to rotate to the angle required by the transport, when the impact lever 220 is in the normal angle range and does not touch the travel switch 310, the signal is reset, the winch 40 stops, thereby the automatic deviation adjusting function is realized.

[0056] The above is only the preferred embodiment of the present application, and does not limit the patent range of the present application, and any equivalent structure or equivalent process transformation, or direct or indirect application in other related technical fields by using the content of the present application specification and drawings, are also included in the patent protection range of the present application.
