Description

Technical Field

[0001] This invention belongs to the field of machinery, and specifically relates to a spring plate hole adjustment device. Background Technology

[0002] Existing mining roller lugs are a type of guide roller used in vertical shaft hoisting containers. The roller lug's shifting rocker arm and elastic buffer are usually fixedly connected by bolts and nuts. However, when the guide roller is running at high speed or encounters an irregular guide, the bolts and nuts are prone to loosening and falling off, causing dangerous accidents and potentially leading to mine shutdowns or production stoppages. Sometimes, the bolts and nuts are threaded together and spot-welded, but spot welding is not conducive to the replacement of the guide roller during maintenance and repair, is time-consuming and labor-intensive, and the overall connection strength of the bolt and nut fixed connection is low. In order to solve the above problems, this invention proposes an elastic plate orifice adjustment device. Summary of the Invention

[0003] This invention is achieved using the following technical solution: The elastic plate hole adjustment device includes an ear hole elastic plate, a connecting swing arm, a support wheel swing arm, an ear hole component, and an ear-stopping plate movement pin. The ear hole elastic plate includes an ear hole. One end of the connecting swing arm is provided with a through-hole movement pin sleeve, and the other end is provided with a connecting support wheel swing arm structure. The ear hole component includes a snap-fit ​​elastic plate component and a snap-fit ​​ear. The snap-fit ​​ear passes through the ear hole, the through-hole movement pin sleeve passes through the ear hole, and the ear-stopping plate movement pin passes through the snap-fit ​​ear and the through-hole movement pin sleeve, so that the snap-fit ​​elastic plate component is tightly attached to the ear hole elastic plate, and the snap-fit ​​elastic plate component moves with the ear-stopping plate. Pins prevent the perforated ears from falling out of the perforated plate holes from both sides of the elastic plate of the perforated ear hole, and position the perforated ears. The perforated ears support the moving pin of the ear-stopping plate, and the moving pin of the ear-stopping plate supports the moving pin bushing of the moving pin of the ear-stopping plate. The moving pin bushing of the moving pin of the ear-stopping plate rotates around the moving pin of the ear-stopping plate. The connecting support wheel swing arm structure is connected to the support wheel swing arm. The support wheel swing arm is pushed by external force to the connecting swing arm, and the connecting swing arm pushes the moving pin of the ear-stopping plate. The moving pin of the ear-stopping plate transmits the external force to the ear perforation component. The ear perforation component pulls the locking elastic plate component, and the locking elastic plate component pushes the perforated ear hole elastic plate to deform and buffer. The buffering rebound force of the perforated ear hole elastic plate quickly straightens and resets the perforated ear hole elastic plate.

[0004] The support wheel swing arm structure includes a connecting adjuster threaded rod and an adjuster threaded sleeve. One end of the connecting adjuster threaded rod or the adjuster threaded sleeve is connected to the through-resistance axial movement pin sleeve. When the connecting adjuster threaded rod is connected to the through-resistance axial movement pin sleeve, one end of the adjuster threaded sleeve is threadedly connected to the connecting adjuster threaded rod, and the other end of the adjuster threaded sleeve is connected to the support wheel swing arm. When the adjuster threaded sleeve is connected to the through-resistance axial movement pin sleeve, one end of the connecting adjuster threaded rod is threadedly connected to the adjuster threaded sleeve, and the other end of the connecting adjuster threaded rod is connected to the support wheel swing arm. The adjuster threaded sleeve includes an adjusting nut and a screw sleeve, and one end of the screw sleeve is provided with a retainer. The adjustable nut has a stop and a boss that engages with the stop to prevent it from detaching from the screw sleeve. The boss engages with the stop to allow the adjustable nut to rotate relative to the screw sleeve and prevent it from slipping off. The adjustable nut is threadedly connected to the adjusting rod. When the position of the support wheel rocker arm needs to be adjusted, the adjustable nut is rotated to move towards the front or rear end of the adjusting rod. The adjustable nut pulls the screw sleeve forward or backward, which in turn pulls the support wheel rocker arm forward or backward, allowing the support wheel rocker arm to operate in the optimal position.

[0005] The aforementioned ear-piercing elastic plate includes a leaf spring ear-piercing elastic plate, which can be a straight ear-piercing elastic plate, an upwardly curved ear-piercing elastic plate, a downwardly curved ear-piercing elastic plate, a medium-curved ear-piercing elastic plate, or a multi-curved ear-piercing elastic plate. When using a downwardly curved ear-piercing elastic plate, an ear-piercing plate hole is provided at the upper part of the downwardly curved ear-piercing elastic plate, and a fixed elastic plate structure is provided at the lower part of the downwardly curved ear-piercing elastic plate.

[0006] The fixed elastic plate structure includes a screw-fixed elastic plate structure, a pin-ear shaft-fixed elastic plate structure, or a slot-fixed elastic plate structure. When using the pin-ear shaft-fixed elastic plate structure, the elastic plate hole adjustment device includes a fixed base. The pin-ear shaft-fixed elastic plate structure includes a fixed elastic plate pin. The fixed base is provided with a through-hole fixed elastic plate pin lug. The through-hole fixed elastic plate pin lug includes a connecting base support and a base through-shaft lug. The connecting base support supports the base through-shaft lug. The through-hole elastic plate includes a connecting base lug. The base through-shaft lug passes through the connecting base lug. The fixed elastic plate pin passes into the connecting base lug, so that the connecting base support is close to the through-hole elastic plate. The fixed elastic plate pin prevents the through-hole elastic plate and the base through-shaft lug from moving. The connecting base support and the fixed elastic plate pin lock the through-hole elastic plate, so that the through-hole elastic plate is fixed on the fixed base.

[0007] The lug plate moving pin is provided with a structure to prevent the lug plate moving pin from falling off at one or both ends. When the lug plate moving pin is provided with a structure to prevent the lug plate moving pin from falling off at one end, the other end of the lug plate moving pin is set as a stop. The stop prevents the lug plate moving pin from moving. The structure to prevent the lug plate moving pin from falling off includes a cotter pin or a spring pin. The cotter pin is inserted into the lug plate moving pin to prevent the lug plate moving pin from falling off the perforated lug.

[0008] The aforementioned lug plate moving pin includes a D-shaped lug plate moving pin, a conical lug plate moving pin, a cylindrical lug plate moving pin, a semi-circular lug plate moving pin, a square lug plate moving pin, or an elliptical lug plate moving pin. When using a D-shaped lug plate moving pin, one side of the D-shaped lug plate moving pin is set as a flat surface. After the D-shaped lug plate moving pin is inserted into the perforated lug, the flat surface of the D-shaped lug plate moving pin is tightly engaged with the perforated lug plate, which can both increase the contact area between the lug plate moving pin and the perforated lug plate and prevent the lug plate moving pin from rotating, so that the elastic plate... The structure of the Kongka adjuster device is more reasonable and compact. When using the conical lug plate moving pin, the corresponding perforated lug is set as a conical hole. After the conical lug plate moving pin passes through the conical hole of the perforated lug, the conical lug plate moving pin and the conical hole are tightly engaged. One side of the conical lug plate moving pin is set as a flat surface. The flat surface of the conical lug plate moving pin is tightly engaged with the perforated hole elastic plate. This can increase the contact area between the lug plate moving pin and the perforated hole elastic plate, and prevent the lug plate moving pin from rotating, making the elastic plate Kongka adjuster device structure more reasonable and compact.

[0009] Ear plate holes include square ear plate holes, rectangular ear plate holes, round ear plate holes, oval ear plate holes, or polygonal ear plate holes.

[0010] Beneficial effects of the invention:

[0011] 1. One end of the connecting swing arm is equipped with a through-hole locking pin sleeve, and the other end is equipped with a connecting support wheel swing arm structure. The ear-hole component is equipped with a snap-fit ​​elastic plate and a through-hole ear. The through-hole ear passes through the ear plate hole, the through-hole locking pin sleeve passes through the ear plate hole, and the through-hole locking pin passes through the through-hole ear and the through-hole locking pin sleeve, so that the snap-fit ​​elastic plate is tightly attached to the ear hole elastic plate. The snap-fit ​​elastic plate and the through-hole locking pin prevent the through-hole ear from falling out of the ear plate hole from both sides of the ear hole elastic plate, thus positioning the through-hole ear. The through-hole ear supports the through-hole locking pin, and the through-hole locking pin supports the through-hole locking pin sleeve. The through-hole locking pin sleeve rotates around the through-hole locking pin. The connecting support wheel swing arm structure is connected to the support wheel swing arm. When the rocker arm is subjected to external force, it pushes the connecting swing arm, which in turn pushes the lug plate moving pin. The lug plate moving pin then transmits the external force to the ear-piercing part. The ear-piercing part pulls the snap-fit ​​elastic plate, which in turn pushes the ear-piercing elastic plate to deform and buffer. The buffered rebound force of the ear-piercing elastic plate quickly straightens and resets the ear-piercing elastic plate. This structure ensures that the snap-fit ​​elastic plate is tightly attached to the ear-piercing elastic plate, resulting in a close fit, large buffered rebound force, and clever use of the lug plate moving pin connection, which increases the overall structural strength. Furthermore, because no bolts or nuts are used in this connection, the defects of bolts and nuts being prone to loosening and falling off are avoided, preventing dangerous situations caused by loose bolts and nuts falling off.

[0012] 2. One end of the adjusting threaded rod or adjusting threaded sleeve is connected to the through-resistance moving pin sleeve. When the adjusting threaded rod is connected to the through-resistance moving pin sleeve, one end of the adjusting threaded sleeve is threadedly connected to the adjusting threaded rod, and the other end of the adjusting threaded sleeve is connected to the support wheel swing arm. When the adjusting threaded sleeve is connected to the through-resistance moving pin sleeve, one end of the adjusting threaded rod is threadedly connected to the adjusting threaded sleeve, and the other end of the adjusting threaded rod is connected to the support wheel swing arm. The adjusting threaded sleeve includes an adjusting nut and a screw sleeve. One end of the screw sleeve is provided with a stop for locking the adjusting nut. The adjusting nut is provided with a resistance adjusting nut that cooperates with the stop for locking the adjusting nut. The adjusting nut boss, which detaches from the screw sleeve, engages with the adjusting nut stop to allow the adjusting nut to rotate relative to the screw sleeve and prevent it from shifting and falling off. The adjusting nut is threadedly connected to the connecting adjuster threaded rod. When the position of the support wheel rocker arm needs adjustment, the adjusting nut is rotated, causing it to move towards the front or rear end of the connecting adjuster threaded rod. The adjusting nut pulls the screw sleeve forward or backward, which in turn pulls the support wheel rocker arm forward or backward, ensuring the rocker arm is in the optimal working position. Using the adjusting nut and screw sleeve not only provides a simple and reliable structure but also high adjustment accuracy, allowing for adjustments to be made at any time according to working conditions.

[0013] 3. Leaf spring through-hole elastic plates include straight through-hole elastic plates, upward-curved through-hole elastic plates, downward-curved through-hole elastic plates, medium-curved through-hole elastic plates, or multi-curved through-hole elastic plates. When using downward-curved through-hole elastic plates, through-holes are provided in the upper part of the downward-curved through-hole elastic plates, and a fixed elastic plate structure is provided in the lower part of the downward-curved through-hole elastic plates. This not only ensures a tight connection, but also increases the buffer stroke of the guide wheel, improving the overall performance of the leaf spring through-hole elastic plates. This results in elastic plate hole adjustment devices with large buffering force, small height, simple structure, complete functions, few vulnerable parts, convenient installation and use, quick maintenance, and low manufacturing cost.

[0014] 4. When using a pin-and-ear shaft to fix the elastic plate structure, the fixed base is equipped with a pin-and-ear piece for fixing the elastic plate. The base support supports the base through-ear, and the base through-ear passes through the connecting base ear hole. The pin for fixing the elastic plate passes into the connecting base ear hole, so that the connecting base support is close to the through-ear elastic plate. The pin for fixing the elastic plate prevents the through-ear elastic plate and the base through-ear from moving. The connecting base support and the pin for fixing the elastic plate lock the through-ear elastic plate, so that the through-ear elastic plate is fixed on the fixed base. The through-ear elastic plate and the fixed base are connected into a whole, which not only has high structural strength, but also facilitates maintenance and replacement, avoiding the situation where replacement is difficult due to the corrosion of bolts and nuts. The structure is simple and ingenious, and highly practical.

[0015] 5. One or both ends of the lug plate moving pin are provided with a structure to prevent the lug plate moving pin from falling off. When one end of the lug plate moving pin is provided with a structure to prevent the lug plate moving pin from falling off, the other end of the lug plate moving pin is set as a stop. The stop prevents the lug plate moving pin from moving. The structure to prevent the lug plate moving pin from falling off includes a cotter pin or a spring pin. The cotter pin is inserted into the lug plate moving pin to prevent the lug plate moving pin from falling off the perforated ear. This not only prevents the lug plate moving pin from moving left and right or falling off, but also makes disassembly and maintenance convenient because the structure using a stop and cotter pin is simple.

[0016] 6. When using the D-shaped lug plate moving pin, one side of the D-shaped lug plate moving pin is set as a flat surface. After the D-shaped lug plate moving pin is inserted into the perforated lug, the flat surface of the D-shaped lug plate moving pin is tightly engaged with the perforated lug plate. This not only increases the contact area between the lug plate moving pin and the perforated lug plate, but also prevents the lug plate moving pin from rotating. This makes the structure of the elastic plate hole adjustment device more reasonable and compact, simple and reliable, easy to disassemble, highly safe, and highly practical.

[0017] 7. When using a tapered lug plate moving pin, the corresponding perforated lug is set as a tapered hole. After the tapered lug plate moving pin passes through the tapered hole of the perforated lug, the tapered lug plate moving pin and the tapered hole are tightly engaged. One side of the tapered lug plate moving pin is set as a flat surface. The flat surface of the tapered lug plate moving pin is tightly engaged with the perforated hole elastic plate. This can increase the contact area between the lug plate moving pin and the perforated hole elastic plate, and prevent the lug plate moving pin from rotating. This makes the elastic plate hole adjustment device more reasonable and compact in structure, convenient to install, has good self-locking properties, simple and reliable structure, and strong practicality.

[0018] 8. The ear plate holes include square ear plate holes, rectangular ear plate holes, round ear plate holes, elliptical ear plate holes, or polygonal ear plate holes. The structure can be adjusted according to different working conditions, and it is safe and convenient to use. Attached Figure Description

Claims

1. A spring plate hole adjustment device, characterized in that: The components include an ear-hole elastic plate, a connecting swing arm, a support wheel swing arm, an ear-hole component, and an ear-stopping plate movement pin. The ear-hole elastic plate includes an ear-hole. One end of the connecting swing arm is equipped with a through-stopping movement pin sleeve, and the other end is equipped with a connecting support wheel swing arm structure. The ear-hole component includes a snap-fit ​​elastic plate component and a through-hole ear. The through-hole ear passes through the ear-hole, the through-stopping movement pin sleeve passes through the ear-hole, and the ear-stopping plate movement pin passes through the through-hole ear and the through-stopping movement pin sleeve, so that the snap-fit ​​elastic plate component is tightly attached to the ear-hole elastic plate. The snap-fit ​​elastic plate component and the ear-stopping plate movement pin prevent perforation from both sides of the ear-hole elastic plate. The ear falls out of the ear-piercing plate hole, positioning the perforated ear. The perforated ear supports the ear-stopping plate moving pin, which in turn supports the through-ear-stopping moving pin bushing. The through-ear-stopping moving pin bushing rotates around the ear-stopping plate moving pin. The connecting wheel swing arm structure is connected to the wheel swing arm. The wheel swing arm is pushed by an external force, which pushes the ear-stopping plate moving pin. The ear-stopping plate moving pin transmits the external force to the ear-piercing part. The ear-piercing part pulls the snap-fit ​​elastic plate part, which pushes the ear-piercing hole elastic plate to deform and buffer.
