Description

Technical Field

[0001] This utility model relates to the field of gearbox technology, specifically to a gearbox structure for mining machinery that is easy to disassemble. Background Technology

[0002] Gearboxes are crucial components widely used in mechanical transmissions. They are extensively employed in wind turbine generators. Gearboxes bear the forces from the wind turbine and the reaction forces generated during gear transmission. They must possess sufficient rigidity to withstand forces and torques, prevent deformation, and ensure transmission quality. Currently, gearboxes typically use bolts to fix the cover to the gearbox body. When repairing the gears inside the gearbox, specialized tools are needed to remove the bolts and take off the cover, which is not only time-consuming but also causes significant inconvenience for workers.

[0003] Patent application number 201920816038.4 discloses a gearbox that is easy to maintain. This utility model discloses a gearbox that is easy to maintain, belonging to the field of gearbox technology. The easy-to-maintain gearbox includes a gearbox body with a cover on top. Multiple lower rectangular through holes and upper rectangular through holes are respectively drilled on the surfaces of the gearbox body and the cover, with corresponding positions. Multiple pairs of positioning blocks are fixedly connected to the surface of the cover, facilitating the removal of the cover from the gearbox body for maintenance of the gears inside. This operation is convenient and saves time. However, when lifting and disassembling the gearbox in narrow spaces in mines, the lifting rings cannot be adjusted freely. In such confined spaces, the crane cannot function effectively, and the lifting center of gravity may not align with the gearbox's center of gravity, potentially causing the gearbox to tilt and preventing proper lifting and maintenance.

[0004] Therefore, in view of this, we studied and improved the existing structure to propose a gearbox structure for mining machinery that is easy to disassemble. Utility Model Content

[0005] The purpose of this invention is to provide a gearbox structure for mining machinery that is easy to disassemble, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a gearbox structure for mining machinery that is easy to disassemble, comprising a gearbox body, guide boxes being provided on both sides of the upper surface of the gearbox body, a bidirectional helical transmission rod being rotatably mounted on the inner surface of the guide box, a servo motor being installed at the end of the bidirectional helical transmission rod, a guide slider being helically mounted on the outer surface of the bidirectional helical transmission rod, and a sliding connection being provided between the guide slider and the guide box, and a rotating seat being provided on the upper surface of the guide slider.

[0007] Preferably, a rotating block is rotatably mounted on the inner surface of the rotating seat, and the rotating block and the inner surface of the rotating seat are configured to be in frictional connection.

[0008] Preferably, the upper surface of the rotating block is provided with a lifting ring, and the inner surface of the lifting ring is set as an arc shape.

[0009] Preferably, the inner surface of the guide box is provided with guide rails on both sides, and the guide rails and the inner surface of the guide slider are slidably connected.

[0010] Preferably, the guide box has ash discharge ports on both lower surfaces, and the ash discharge ports are set as bevels.

[0011] Preferably, both sides of the rotating seat are provided with connecting plates, and the upper surface of the connecting plates is provided with connecting pads, and a limit rod is slidably installed through the surface of the connecting pads.

[0012] Preferably, the outer surface of the limiting slide bar is provided with a return spring, and the return spring and the connecting washer are fixedly connected.

[0013] Preferably, the lower surface of the limiting slide bar is provided with a brush, and the brush is configured to be in contact with the outer surface of the bidirectional helical transmission rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model, through the arrangement of a gearbox body, guide box, servo motor, guide slide rail, ash discharge port, bidirectional spiral transmission rod, guide slider, rotating seat, rotating block and lifting ring, allows the position of the lifting ring to be adjusted when the gearbox body needs to be disassembled and repaired, so that the lifting center of gravity coincides with the center of gravity of the gearbox body, avoiding tilting and swaying during lifting, reducing the risk of component collision, and improving disassembly efficiency. At the same time, in space-constrained areas such as mining sites, the lifting ring can slide to adjust the lifting point to avoid surrounding equipment or obstacles, without the need to repeatedly move the lifting equipment.

[0016] 2. This utility model, through the setting of a connecting plate, connecting gasket, limiting slide rod, return spring and brush, allows the brush to remove dust and impurities remaining on the outer surface of the bidirectional helical transmission rod when the bidirectional helical transmission rod drives the guide slider to move. This prevents the guide slider from getting stuck due to dust and thus avoids it from properly driving the lifting ring to move. Attached Figure Description

[0022] 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.

[0023] like Figures 1-3 As shown, a gearbox structure for mining machinery that is easy to disassemble includes a gearbox body 1. Guide boxes 101 are provided on both sides of the upper surface of the gearbox body 1, and a bidirectional helical transmission rod 2 is rotatably mounted on the inner surface of the guide box 101. A servo motor 102 is installed at the end of the bidirectional helical transmission rod 2. With this technical solution, the position of the lifting ring 204 can be adjusted when the gearbox body 1 needs to be disassembled and repaired, so that the lifting center of gravity coincides with the center of gravity of the gearbox body 1, avoiding tilting and swaying during lifting, reducing the risk of component collision, and improving disassembly efficiency. At the same time, the lifting ring 204 can also be adjusted by sliding the lifting point in confined areas such as mining sites to avoid surrounding equipment or obstacles without repeatedly moving the lifting equipment.

[0024] Furthermore, a guide slider 201 is spirally mounted on the outer surface of the bidirectional helical transmission rod 2, and the guide slider 201 and the guide box 101 are configured to slide. With this technical solution, the lifting ring 204 can be driven to slide by the setting of the guide slider 201, so as to complete the adjustment of the lifting ring 204.

[0025] Furthermore, a rotating seat 202 is provided on the upper surface of the guide slider 201, and a lifting ring 204 is provided on the upper surface of the rotating block 203. The inner surface of the lifting ring 204 is set as an arc. With this technical solution, the lifting ring 204 can be driven to adjust its angle by setting the rotating seat 202, so as to facilitate the calibration of the center of gravity.

[0026] Furthermore, guide rails 103 are provided on both sides of the inner surface of the guide box 101, and the guide rails 103 and the inner surface of the guide slider 201 are slidably connected. With this technical solution, the guide slider 201 can be guided and positioned by the guide rails 103.

[0027] Furthermore, the guide box 101 has dust discharge ports 104 on both sides of its lower surface, and the dust discharge ports 104 are set as inclined surfaces. With this technical solution, the dust swept down by the guide slider 201 during its movement can be discharged through the setting of the dust discharge ports 104.

[0028] like Figure 4 As shown, connecting plates 3 are provided on both sides of the rotating seat 202, and connecting gaskets 301 are provided on the upper surface of the connecting plates 3. A limiting slide rod 302 is slidably installed through the surface of the connecting gasket 301. A return spring 303 is provided on the outer surface of the limiting slide rod 302, and the return spring 303 and the connecting gasket 301 are fixedly connected. In this technical solution, by setting the return spring 303, the brush 304 can always be in contact with the outer surface of the bidirectional spiral transmission rod 2 by compression and reset.

[0029] Furthermore, a brush 304 is provided on the lower surface of the limiting slide bar 302, and the brush 304 is in contact with the outer surface of the bidirectional helical transmission rod 2. With this technical solution, the brush 304 can remove dust and impurities remaining on the outer surface of the bidirectional helical transmission rod 2 when the bidirectional helical transmission rod 2 drives the guide slider 201 to move. This prevents dust from causing the guide slider 201 to jam and prevent it from driving the lifting ring 204 to move normally.

[0030] Working principle: When using this easily disassembled gearbox structure for mining machinery, firstly, the servo motor 102 is started to drive the bidirectional screw transmission rod 2 to rotate. Through the screw transmission, the guide slider 201 slides along the guide rail 103 on the inner surface of the guide box 101, thereby flexibly adjusting the position of the lifting ring 204 so that it can accurately match the hook spacing and lifting angle of the crane.

[0031] During the sliding of the guide slider 201, the brushes 304 on both sides of its rotating seat 202, under the continuous reset pressure of the return spring 303, closely adhere to the outer surface of the rotating bidirectional helical transmission rod 2, sweeping away the attached dust and debris in real time. This design effectively avoids the adjustment obstruction caused by foreign objects jamming the guide slider 201 during sliding, ensuring smooth and accurate adjustment of the position of the lifting ring 204.

[0032] After the lifting ring 204 is adjusted to the correct position, securely connect the hook of the lifting equipment to the lifting ring 204, start the lifting equipment to smoothly lift and separate the gearbox body 1 to the designated maintenance area, and then proceed with the subsequent disassembly and maintenance work. This is the working principle of this easily disassembled gearbox structure for mining machinery.
