Description

Technical Field

[0001] This utility model relates to the field of prospecting equipment technology, and in particular to a mobile buffer and shock-absorbing base for a prospecting winch. Background Technology

[0002] In mining exploration, electric winches are indispensable traction and hoisting equipment. During startup, braking, and sudden load changes, winches generate enormous impact forces and continuous high-frequency vibrations. Traditional rigid bases or simple shock-absorbing designs cannot effectively absorb this energy, causing vibrations to be directly transmitted to the base structure and the winch itself. Over time, this can easily lead to loosening, fatigue, or even damage to internal winch parts, shortening the equipment's lifespan.

[0003] Traditional mobile electric winches transmit road bumps almost without attenuation to the winch via the tires and rigid axles of the base. This affects the winch's stability during movement and can cause the fixed load to slip due to violent shaking, potentially leading to accidents. Current mobile electric winches often use single shock-absorbing elements, such as springs or rubber pads, which have limited shock absorption performance. Furthermore, the rigid connection between the axle and the load-bearing platform creates a vibration transmission path that bypasses the main shock absorber, significantly weakening the overall shock absorption effect. Utility Model Content

[0004] This utility model addresses the technical problem of limited vibration reduction performance and poor overall vibration reduction effect of mobile electric winches in mining exploration. It provides a mobile buffer and vibration damping base for mining winches, including a load-bearing platform. The load-bearing platform is a rectangular structure made of channel steel. Two axle mounting plates are provided below the load-bearing platform. Each axle mounting plate has two connecting ears on each side. A hydraulic damper is connected between each connecting ear and the load-bearing platform. The top of the hydraulic damper is fixedly connected to the inner side of the load-bearing platform.

[0005] Each of the aforementioned bearing mounting plates has a bearing fixedly connected to each of its two bottom sides, and a sliding bearing is provided in the center of each bearing.

[0006] The bottom of the load-bearing platform is provided with a top groove, and the top of each of the bearing mounting plates is provided with a bottom groove that is symmetrical to the top groove. The top groove and the bottom groove are provided with a buffer ring.

[0007] Preferably, in the above technical solution, the top and bottom edges of the buffer ring are provided with side protrusions, and the side protrusions are matched with the top slot and the bottom slot to ensure that the buffer ring is embedded between the load-bearing platform and the bearing mounting plate.

[0008] Preferably, in the above technical solution, gaps are left between the top and bottom of the buffer ring and the load-bearing platform and the bearing mounting plate, respectively, and the height of the gaps is 10-20mm.

[0009] Preferably, in the above technical solution, the buffer ring is a hollow structure and filled with highly elastic rubber.

[0010] Preferably, in the above technical solution, the outer shell of the buffer ring is made of wear-resistant polyurethane material.

[0011] Preferably, in the above technical solution, a "U"-shaped groove is provided on the top of the connecting ear, and a connecting pin is fixedly connected in the "U"-shaped groove.

[0012] Preferably, in the above technical solution, the bottom of the hydraulic damper is provided with a damper arm end, and the damper arm end is sleeved on the connecting pin.

[0013] Preferably, in the above technical solution, a wear-resistant and shock-absorbing layer is laid in the "U"-shaped groove.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This invention utilizes a hydraulic damper between the load-bearing platform and the axle mounting plate to form the first stage of vibration reduction, efficiently converting impact kinetic energy into heat energy for dissipation, thereby absorbing high-frequency vibrations and rapidly suppressing rebound. A buffer ring forms the second stage of vibration reduction. Under normal operating conditions, the buffer ring is under slight compression and does not bear the main load. When a large impact occurs, causing the hydraulic damper's stroke to approach its limit, the buffer ring will contact and compress, providing additional, gentler cushioning force to prevent rigid collisions and continuously absorb low-frequency swaying from the road surface during movement.

[0016] This invention uses axle seats and sliding bearings on an axle seat mounting plate to connect the axle to the load-bearing platform above. The sliding bearings allow for slight wobbling, avoiding the rigid transmission of torsional loads to the platform and ensuring that the shock absorption system can work independently and smoothly.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-4As shown, this utility model discloses a mobile buffer and shock-absorbing base for a mining winch, comprising a load-bearing platform 1. The load-bearing platform 1 is a rectangular structure formed by connecting channel steel. The channel steel in the load-bearing platform 1 can be connected by a combination of welding and bolting, providing extremely high bending and torsional strength to ensure that the platform does not deform under heavy loads and is used to firmly fix the electric winch. Two shaft mounting plates 3 are provided below the load-bearing platform 1. Each shaft mounting plate 3 has two connecting ears 51 on each side. Each connecting ear 51 is connected to the load-bearing platform 1 by a hydraulic damper 5. The top of the hydraulic damper 5 is fixedly connected to the inner side of the load-bearing platform 1. The connection method between the hydraulic damper 5 and the load-bearing platform 1 can also be a movable connection using the connecting ears 51, or the arm end of the top of the hydraulic damper 5 can be welded to the load-bearing platform 1 for a fixed connection. A "U"-shaped groove 511 is provided on the top of the connecting ear 51, and a connecting pin 512 is fixedly connected within the "U"-shaped groove 511. The bottom of the hydraulic damper 5 is provided with a damper arm end 52, which is sleeved on the connecting pin 512. This enables the damper arm end 52 of the hydraulic damper 5 to be movably connected to the connecting ear 51. By utilizing the contraction and extension of multiple hydraulic dampers 5 in different directions, the range of motion of the axle mounting plate 3 is no longer restricted, thereby enhancing the vibration reduction effect of the hydraulic damper 5 on the electric winch. A wear-resistant damping layer 513 is laid in the "U"-shaped groove 511. The wear-resistant damping layer 513 can reduce frictional loss when the damper arm end 52 and the connecting ear 51 move, and also reduce the horizontal vibration impact. Each axle mounting plate 3 has a fixed axle seat 4 on each side of its bottom. A sliding bearing 41 is provided in the center of the axle seat 4. The axle is connected to the upper load-bearing platform 1 through the axle seat 4 with the sliding bearing 41. The sliding bearing 41 allows for a small relative displacement and deflection between the axle and the load-bearing platform 1 on the horizontal plane. When one tire passes over an obstacle, the axle on that side moves upward. Since the connection point is located below the hydraulic damper 5 and connected via the sliding bearing 41, this upward force first compresses the hydraulic damper 5 at that angle, rather than directly pushing the load-bearing platform 1. At the same time, the slight wobble allowed by the sliding bearing 41 prevents the torsional load from being rigidly transmitted to the load-bearing platform 1, ensuring that the shock absorption system can work independently and smoothly without being jammed due to axle deformation.

[0025] It should be further explained that the bottom of the load-bearing platform 1 is provided with a top groove 11, and the top of each bearing mounting plate 3 is provided with a bottom groove 31 that is symmetrical to the top groove 11. A buffer ring 2 is provided within the top groove 11 and the bottom groove 31. The top and bottom edges of the buffer ring 2 are provided with side protrusions 21, which match the top groove 11 and the bottom groove 31 to ensure that the buffer ring 2 is embedded between the load-bearing platform 1 and the bearing mounting plate 3. The top groove 11 has a cross-section that is wider at the top and narrower at the bottom, forming a "T" shape. The bottom groove 31 has a cross-section that is wider at the bottom and narrower at the top, forming an inverted "T" shape. The top groove 11 and the bottom groove 31 are symmetrical. The buffer ring 2 has an "I" shaped cross-section, which fits perfectly between the top groove 11 and the bottom groove 31. The top and bottom of the buffer ring 2 have gaps 6 between them and the load-bearing platform 1 and the shaft mounting plate 3, respectively, with a height of 5-20mm. When the equipment is stationary and under static load, a specific vertical clearance is designed between the buffer ring 2 and the load-bearing platform 1 and the shaft mounting plate 3. When the hydraulic damper is in its free length or static compression position, there is a gap between the top of the buffer ring 2 and the bottom of the groove on the lower surface of the load-bearing platform 1, and a gap between the bottom of the buffer ring 2 and the bottom of the groove on the upper surface of the shaft mounting plate 3. These gaps are not equal; under gravity, the gap between the buffer ring 2 and the lower surface of the load-bearing platform 1 is much larger than the gap between the buffer ring 2 and the upper surface of the shaft mounting plate 3. The buffer ring 2 has a hollow structure and is filled with highly elastic rubber 22. The highly elastic rubber 22 provides stable and durable elastic support. The outer shell of the buffer ring 2 is made of wear-resistant polyurethane material. Wear-resistant polyurethane possesses excellent toughness, abrasion resistance, and tear resistance, enabling it to withstand repeated friction with metal components. Under normal operating conditions, it operates under slight or no pressure, not bearing the primary load. When encountering a large impact, causing the hydraulic damper 5 to approach its stroke limit, the buffer ring 2 will contact and compress, providing additional, gentler cushioning force to prevent rigid collisions. During movement, it also continuously absorbs low-frequency vibrations from the road surface. At this point, the two-stage damping system operates in series, with the buffer ring 2 acting as the last line of defense to prevent hard collisions with metal components.

[0026] This invention utilizes a hydraulic damper between the load-bearing platform and the axle mounting plate to form the first stage of vibration reduction, efficiently converting impact kinetic energy into heat energy for dissipation, thereby absorbing high-frequency vibrations and rapidly suppressing rebound. A buffer ring forms the second stage of vibration reduction. Under normal operating conditions, the buffer ring is under slight compression and does not bear the main load. When a large impact occurs, causing the hydraulic damper's stroke to approach its limit, the buffer ring will contact and compress, providing additional, gentler cushioning force to prevent rigid collisions and continuously absorb low-frequency swaying from the road surface during movement. Through the axle mount and sliding bearing on the axle mounting plate, the axle is connected to the upper load-bearing platform via the sliding bearing axle mount. The sliding bearing allows for slight swaying, avoiding the rigid transfer of torsional loads to the platform, ensuring the vibration reduction system can operate independently and smoothly. This solves the technical problem of limited vibration reduction performance and overall poor vibration reduction effect in mobile electric winches during mining exploration.

[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
