Description

Technical Field

[0001] The utility model belongs to the technical field of circular stockpile and reclaiming equipment, in particular to an adaptive tightening support device for a stockpile reclaiming mechanism. Background Art

[0002] Circular stockpiles are typically reclaimed using a combination of a scraper reclaimer and a belt stacker. In a scraper reclaimer, the wire rope that pulls the scraper reclaimer up and down is routed around the support arm of the vertical frame. The support arm primarily provides support for the scraper reclaimer. To ensure structural stability, tie rods are typically used to connect the support arm and the load-bearing arm to form a triangular stable structure. The multiple tie rod segments that make up the tie rod are connected using bolts and nuts. When a tie rod experiences a significant amount of tension from the support arm at a given moment, the bolts can easily break, causing the tie rod to fail. However, if a bolt breaks, there's no way to maintain the tension in the tie rod. Consequently, the tightening force on the support arm drops dramatically, impacting the stability and safety of the support arm's support of the scraper reclaimer. Summary of the Invention

[0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the utility model provides an adaptive tightening support device for a material pile reclaiming mechanism. When the connection between the pull rod sections is damaged, the telescopic tightening mechanism can be retracted to maintain the tensioning state of the pull rod on the support arm, thereby improving the stability and safety of the support arm in supporting the scraper reclaimer.

[0004] Technical solution: To achieve the above-mentioned purpose, the utility model provides an adaptive tightening support device for a material pile reclaiming mechanism, comprising a scraper reclaimer oscillatingly mounted on a vertical frame, the scraper reclaimer being pulled by a wire rope of a winch, and a triangular support structure formed between a support arm supporting the wire rope, a load-bearing arm, and a pull rod;

[0005] The pull rod is composed of multiple pull rod segments coaxially connected by a locking connector, and a telescopic tensioning mechanism is connected in parallel between adjacent pull rod segments; when the locking connector is damaged by tension and unlocked, the telescopic tensioning mechanism contracts and tightens the adjacent pull rod segments to maintain the tension state of the pull rod on the triangular support structure.

[0006] Furthermore, it includes an unlocking state detection device, and each adjacent pull rod segment is connected with an unlocking state detection device, and the unlocking state detection device is interlocked with the telescopic tensioning mechanism.

[0007] Furthermore, the unlocking state detection device is a pressure sensor spring installed between adjacent pull rod sections through a sensor seat.

[0008] Furthermore, it includes a connecting portion corresponding to the telescopic tensioning mechanism, and the telescopic tensioning mechanism is connected to the pull rod section through the connecting portion.

[0009] Furthermore, the locking connector is a bolt and nut assembly that locks and connects adjacent pull rod sections.

[0010] Furthermore, the bolt head and the side surfaces of the nut of the bolt and nut assembly are both provided with anti-loosening blocks in close contact with each other, and the anti-loosening blocks are fixedly arranged relative to the pull rod section.

[0011] Beneficial effects: The utility model connects a telescopic tensioning mechanism between adjacent pull rod sections that constitute the pull rod. When the connection between the pull rod sections is damaged, the pull rod can be retracted to maintain the tensioning state of the support arm, thereby improving the stability and safety of the support arm supporting the scraper reclaimer, and is suitable for large-scale promotion and application. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Attachment Figure 1 This is a schematic structural diagram of a specific application embodiment of the present utility model;

[0013] Attachment Figure 2 This is an enlarged schematic diagram of the structure of the pull rod part. DETAILED DESCRIPTION

[0014] The present invention will be further described below in conjunction with the accompanying drawings.

[0015] As attached Figure 1 and attached Figure 2 As shown, an adaptive tightening support device for a material pile reclaiming mechanism includes a scraper reclaimer 6 swingably mounted on a vertical frame 1. The scraper reclaimer 6 is pulled by a wire rope 7 of a winch 5. A triangular support structure is formed between the support arm 2 supporting the wire rope 7 and the load-bearing arm 3 and the pull rod 4. The pull rod 4 is composed of multiple pull rod segments 40 coaxially connected by a locking connector 4.1. A telescopic tensioning mechanism 8 is connected in parallel between adjacent pull rod segments 40. When the locking connector 4.1 is damaged by tension and unlocked, the telescopic tensioning mechanism 8 retracts and tightens adjacent pull rod segments 40 to maintain the tension state of the pull rod 4 on the triangular support structure. The utility model connects the telescopic tensioning mechanism 8 between adjacent pull rod segments 40 constituting the pull rod 4. In the event of damage at the connection of the pull rod segments 40, the mechanism can retract to maintain the tension state of the pull rod 4 on the support arm 2, thereby improving the stability and safety of the support arm 2 on the scraper reclaimer 6.

[0016] The present invention includes an unlocked state detection device 9, which is connected between adjacent pull rod sections 40 and is interlocked with the telescopic tensioning mechanism 8. The locking connector 4.1 is the first barrier to maintain the tension of the pull rod 4. When the locking connector 4.1 is damaged, the unlocked state detection device 9 detects the unlocked state, and the interlocked telescopic tensioning mechanism 8 contracts, thereby restoring the tension of the pull rod 4 on the support arm 2, realizing automated detection and control.

[0017] More specifically, the unlocking state detection device 9 is a pressure sensor spring installed between adjacent pull rod segments 40 through a sensor seat 91. It includes a connecting portion 81 corresponding to the telescopic tensioning mechanism 8, and the telescopic tensioning mechanism 8 is connected to the pull rod segment 40 through the connecting portion 81. The locking connector 4.1 is a bolt and nut assembly that locks and connects adjacent pull rod segments 40. In the present utility model, the telescopic tensioning mechanism 8 can optionally use an electric hydraulic cylinder. When the bolt breaks, the pressure sensor spring is stretched and the pressure value decreases, then the interlocking telescopic tensioning mechanism 8 is shortened, pulling the pull rod segment 40 until each pull rod segment 40 returns to its original position. When returning to its original position, the pressure value detected by the pressure sensor spring is also the same as before.

[0018] In order to prevent the nut from loosening and the bolt from slipping, the bolt head and the side surface of the nut of the bolt and nut assembly are both provided with an anti-loosening block 4.2 in close contact with each other. The anti-loosening block 4.2 is fixed relative to the pull rod section 40.

[0019] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
