Description

Technical Field

[0001] The invention relates to the technical field of underground mobile tools, and in particular to a supporting wheel connection structure on a mining passenger hanger. Background Art

[0002] On the overhead passenger hanger, the supporting wheel is its key supporting and guiding component. Its main function is to support and guide the hanger to slide or roll smoothly on the load-bearing wire rope during the operation of the hanger, to ensure smooth operation, reduce friction resistance, and prevent the hanger from getting off the rope or swinging excessively during operation; the supporting wheel is installed on the hanger column through a specific connecting structure; but the supporting wheel connection structure in the prior art generally has the following deficiencies: 1. Since the supporting wheel is a wearing part, it needs to be inspected, maintained and replaced regularly, but the disassembly and assembly process of the supporting wheel under the existing connection structure is time-consuming and labor-intensive, especially in the underground environment with limited space, which greatly increases the maintenance workload and downtime; 2. Due to the harsh operating environment underground in the mine, the rigidity and anti-loosening performance of the connection structure are extremely high. The existing structure is prone to loosening, deformation or displacement during long-term operation, which affects the support and guiding effect of the supporting wheel and even brings safety hazards; this is the main problem currently faced. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a supporting wheel connection structure on a mining passenger hanger to solve the problems of difficult installation and disassembly, insufficient connection reliability and stability of the supporting wheel connection structure on the current hanger.

[0004] In order to solve the above problems, the present invention provides the following technical solutions: A supporting wheel connection structure on a passenger hanger for mining; it includes a vertically placed hanging column; a positioning block is provided on the outer side wall of the hanging column; a functional card block is detachably mounted on the positioning block; a card slot is provided on the side of the functional card block opposite to the positioning block; a cross bar is placed in the card slot; the length of the cross bar is greater than that of the functional card block; U-bolts are provided on the upper and lower sides of the functional card block; the middle part of the U-bolt is clamped on the hanging column; a pressure plate is installed on the back side of the cross bar; a through hole is provided on the pressure plate; the two protruding ends of the U-bolt pass through the functional card block and the cross bar and then pass through the through hole in the pressure plate, and the U-bolt presses the pressure plate onto the functional card block by cooperating with a nut.

[0005] Preferably, the suspension column is a cylindrical structure; the positioning block is a truncated cone structure protruding radially along the suspension column; and the diameter of the positioning block is smaller than the diameter of the cross section of the suspension column where the positioning block is located.

[0006] Preferably, the functional card block is a block structure similar to a cuboid, and a concave surface is provided on the back end face of the functional card block, the shape of which is consistent with the shape of the outer wall of the suspension column; the card slot is provided in the middle position of the concave surface.

[0007] Preferably, the card slot is a through slot along the length direction of the functional card block, and the slot depth is smaller than the width of the cross bar.

[0008] Preferably, the cross bar is a straight bar structure similar to a hollow square steel, the cross section of the slot is U-shaped, and one side of the cross bar can be inserted into the slot.

[0009] Preferably, there are two pressing plates in total; the pressing plates are strip-shaped structures, and two through holes are opened on each pressing plate; the two pressing plates are respectively installed on the protruding ends on the same side of the two U-shaped bolts located above and below the functional block.

[0010] Furthermore, two limit blocks are provided on the end surface of the cross bar facing the pressure plate; the two limit blocks are respectively attached to the relative end surface positions between the two pressure plates.

[0011] The beneficial effects of the present invention include the following aspects: 1. Through the modular design of the functional block and the positioning block, combined with the locking structure of the U-bolt and the pressure plate, the crossbar as the support component of the roller can be quickly disassembled and assembled. During maintenance, only the nut needs to be loosened and the pressure plate removed to pull out the crossbar, without dismantling the davit or damaging the main structure. 2. The truncated cone structure of the positioning block fits tightly with the concave surface of the functional block to resist radial displacement; the U-bolt rigidly covers the sling, providing bidirectional restraint; the pressure plate and the limit block form axial positioning to prevent the crossbar from moving; this triple limit function can effectively cope with high-frequency vibration conditions in underground mines, completely eliminating the risk of loosening, deformation, or displacement; 3. The box-type frame composed of the crossbar limit block and the double pressure plate evenly distributes the impact load during the operation of the supporting roller to the davit, reducing stress concentration and maintaining support stability; 4. Functional blocks, crossbars and other vulnerable parts can be replaced individually without disassembling the entire hanger. The standardized modular design increases the commonality of spare parts and reduces production management costs.

[0012] 5. The connection is reliable and can effectively prevent coal dust or muddy water from invading the connection position. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: Example: Reference Figure 1 The present embodiment provides a supporting wheel connection structure on a mining passenger hanger; it includes a hanging column 1 placed vertically; a positioning block 2 is provided on the outer side wall of the hanging column 1; a functional card block 3 is detachably installed at the positioning block 2; a card slot 4 is opened on the side of the functional card block 3 opposite to the positioning block 2; a cross bar 5 is placed at the card slot 4; the length of the cross bar 5 is greater than the length of the functional card block 3; the cross bar 5 extends out of the two ends of the functional card block 3 for directly installing the supporting wheel assembly; U-bolts 6 are provided on the upper and lower sides of the functional card block 3; the middle part of the U-bolt 6 is stuck on the hanging column 1; a pressure plate 7 is installed on the back side of the cross bar 5; a through hole is opened on the pressure plate 7; the two protruding ends of the U-bolt 6 pass through the functional card block 3 and the cross bar 5 and then pass through the through hole on the pressure plate 7, and the U-bolt 6 presses the pressure plate 7 on the functional card block 3 by cooperating with the nut. The nut should preferably be a self-locking anti-loosening nut, or be equipped with anti-loosening elements such as spring washers and retaining washers to ensure the long-term stability of the connection under continuous vibration conditions underground.

[0015] The suspensor post 1 is a cylindrical structure; the positioning block 2 is a frustoconical structure protruding radially from the suspensor post 1. The diameter of the positioning block 2 is smaller than the cross-sectional diameter of the suspensor post 1 where it is located. In this embodiment, the positioning block and the suspensor post are integrally formed or secured by high-strength welding, ensuring its reliability and accuracy as a mounting base for the functional block 3. Furthermore, the frustoconical positioning block not only provides axial positioning, but also forms a radial limit for the functional block 3 on its side, preventing it from rotating around the suspensor post 1.

[0016] Functional block 3 is a rectangular block with a concave surface on its back end, shaped to match the outer wall of sling 1. Slot 4 is located in the center of this concave surface. This concave surface ensures wide, stable contact with both the outer perimeter of sling 1 and the side of positioning block 2, ensuring reliable connection.

[0017] The slot 4 is a through slot along the length of the functional card block 3, and the depth of the slot 4 is less than the width of the crossbar 5. This design ensures that when the crossbar 5 is placed in the slot 4, part of its side surface can firmly rest against the side wall of the slot 4, while part of its bottom or top surface can also be effectively supported, forming a stable support relationship.

[0018] The cross bar 5 is a straight bar structure similar to a hollow square steel. The cross section of the slot 4 is U-shaped, and one side of the cross bar 5 can be inserted into the slot 4.

[0019] Two pressure plates 7 are provided; each plate is strip-shaped and has two through-holes. They are mounted on the protruding ends of the upper and lower U-bolts 6 on the same side of the functional block 3. The two independent pressure plates 7 allow for separate manipulation of the upper and lower nuts during removal or installation, providing greater flexibility, a significant advantage when space is limited underground.

[0020] Two limit blocks 8 are also provided on the end surface of the crossbar 5 facing the pressure plate 7; the two limit blocks 8 are respectively attached to the opposing end surfaces between the two pressure plates 7. The limit blocks 8 and the crossbar 5 can be welded or integrally formed. Their function is not only to limit the axial movement of the crossbar 5, but more importantly, they form a local rigid frame together with the pressure plate 7, significantly improving the installation rigidity and impact resistance of the crossbar 5 on the functional block 3.

[0021] When installing the device of the present invention, you can refer to the following process: 1. Pre-install the upper and lower U-bolts 6 at the predetermined height of the sling 1.

[0022] 2. Fit the concave surface of the functional block 3 to the outer wall of the sling 1 and make it close to the side and end faces of the positioning block 2 to complete radial and circumferential positioning.

[0023] 3. Align the end of the cross bar 5 where the support wheel needs to be installed with the slot 4 on the functional block 3 and push it into place smoothly. At this time, the end limit block 8 of the cross bar 5 should be in the designed position.

[0024] 4. Place two pressure plates 7 on the back side of the crossbar 5 (away from the center of the suspender), corresponding to the four protruding ends of the upper and lower U-bolts 6. Make sure the pressure plates 7 are located between the limit blocks 8.

[0025] 5. Sequentially place flat washers and spring washers (or other anti-loosening components) on the four protruding ends of the U-bolts 6, then tighten the anti-loosening nuts. Tighten the nuts step by step in a symmetrical, cross-section order, ensuring that the pressure plate 7 evenly and firmly presses the functional block 3 and crossbar 5 against the positioning block 2 and the sling 1, and that the limit block 8 fits tightly against the side of the pressure plate 7, completing the assembly of the entire connection structure.
