Description

Technical Field

[0001] This utility model belongs to the field of gearbox technology, and in particular relates to a quick-fix installation structure for gearboxes. Background Technology

[0002] A gearbox is a mechanical transmission device that converts speed and torque through the meshing of gears of different specifications. It is widely used in industrial equipment, transportation vehicles, and other fields. The quick-fix installation structure is designed to simplify the installation and disassembly process, reduce downtime during equipment maintenance or replacement, improve operating efficiency, and ensure the connection accuracy and stability between the gearbox and the power source and load, thus meeting the needs of industrial production for equipment flexibility and rapid response.

[0003] However, the existing gearboxes have a relatively complex fixing method, which results in a long fixing time, increased labor costs, and higher requirements for the technical proficiency of the operators, thus affecting the assembly stability of the gearbox. Utility Model Content

[0004] The purpose of this utility model is to provide a quick-fixing and installation structure for gearboxes. By setting a fixing part, it solves the problem that the fixing method of existing gearboxes is relatively complicated, which leads to long fixing time, increased labor input costs, and higher technical proficiency requirements for operators, thus affecting the assembly stability of the gearbox.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a quick-fixing and installation structure for a gearbox, comprising a mounting base and a gearbox disposed on top of the mounting base, and further comprising: a fixing part mounted on the mounting base; an anti-reverse part mounted on the fixing part; the fixing part including a drive assembly mounted inside the mounting base; and a fixing component mounted on top of the mounting base and connected to the drive assembly; the drive assembly including a first rotating shaft rotatably connected between the inner top wall of the rectangular frame of the mounting base and the base plate, the outer wall of the first rotating shaft being fixedly connected to a gear, two rectangular rings being fixedly connected to the inner top wall of the rectangular frame of the mounting base near the gear, each of the two rectangular rings having a rack passing through the ring, both racks meshing with the gear, a second rotating shaft rotatably connected to the front side of the mounting base, the rear side of the second rotating shaft extending into the mounting base, and a transmission component disposed on the second rotating shaft; wherein, the two racks are located on the front and rear sides of the gear and are staggered, respectively, and the mounting base is composed of a base plate and an internally hollow rectangular frame, the rectangular frame being fixed to the upper surface of the base plate;

[0007] The transmission component includes bevel gears fixedly connected to the outer walls of the first and second rotating shafts, respectively. The two bevel gears mesh with each other, and a handle is fixedly connected to the outer wall of the second rotating shaft. Both bevel gears are located inside the mounting base, with the bevel gear on the outer wall of the first rotating shaft located below the gears. The handle is located on the front side of the mounting base, providing a power source for clamping and loosening the fixing component, thereby achieving efficient power transmission and direction conversion.

[0008] Furthermore, the fixing component includes two limiting slide grooves formed on the top of the rectangular frame of the mounting base and extending in the left-right direction. The inner walls of the two limiting slide grooves are slidably connected to sliders. The bottoms of the two sliders are respectively fixedly connected to the ends of the two racks away from the gears. The tops of the two sliders are fixedly connected to fixing plates. The sides of the two fixing plates that are close to each other are fixedly connected to anti-slip buffer pads. The two sliders are located on the tops of the two racks, which ultimately achieves a stable clamping of the gearbox and ensures the positional stability after installation.

[0009] Furthermore, the anti-reverse component includes a support assembly mounted on a mounting base; and a limiting assembly mounted on the second rotating shaft.

[0010] Furthermore, the support assembly includes a support plate fixedly connected to the front side of the mounting base, a telescopic rod fixedly connected to the left side of the support plate, a rectangular plate fixedly connected to the left side of the telescopic rod, and an elastic element provided on the telescopic rod; wherein, the support plate, the telescopic rod, and the rectangular plate are all located on the right side of the second rotating shaft;

[0011] The elastic element includes a spring sleeved on the outer wall of the telescopic rod. The left side of the spring is fixedly connected to the rectangular plate, and the right side of the spring is fixedly connected to the support plate. The spring is located between the rectangular plate and the support plate to ensure stable engagement between the limiting block and the ratchet.

[0012] Furthermore, the limiting component includes a ratchet fixedly connected to the outer wall of the second rotating shaft, and a limiting block fixedly connected to the left side of the rectangular plate. The limiting block is adapted to the ratchet. The limiting block is located on the right side of the ratchet, and the two sides of the ratchet teeth that mate with the limiting block are a straight surface and an arc surface, respectively. The straight surface of the limiting block and the straight surface of the ratchet teeth are in contact to prevent the fixing component from loosening and to ensure the durability of the gearbox's fixed state.

[0013] This utility model has the following beneficial effects:

[0014] 1. By setting a fixing part, when in use, the gearbox is placed on top of the mounting base. Turning the handle will drive the second rotating shaft to rotate clockwise. Through the transmission of two bevel gears, the first rotating shaft will rotate counterclockwise. The first rotating shaft will then drive two racks to slide on the corresponding rectangular rings and move closer to each other through the gears. Then, the slider will move closer and slide synchronously in the limit groove. With the help of the fixing plate, the two anti-slip buffer pads will be used to fix the gearbox. Reversing the operation of the handle can release the fixation, which reduces the difficulty of operation, relaxes the technical requirements of the operator, reduces installation deviation, ensures the stability of gearbox assembly, and reduces labor and time costs.

[0015] 2. By setting an anti-reverse rotation part, when the second rotating shaft rotates clockwise, it will drive the ratchet to rotate clockwise synchronously. The ratchet presses the rectangular plate through the limit block, causing the rectangular plate to move the limit block to the right and away from the ratchet. During this process, the telescopic rod and the spring are compressed and deformed, and the spring generates elastic force. When the limit block corresponds to another groove of the ratchet, under the action of the spring force, the rectangular plate drives the limit block to engage with the ratchet again. This process is repeated to achieve clockwise rotation of the ratchet. At the same time, the action of the direct surface of the limit block and the direct surface of the ratchet restricts the counterclockwise rotation of the second rotating shaft. When it is necessary to rotate the second rotating shaft counterclockwise to release the gearbox fixation, pulling the rectangular plate to move the limit block away from the ratchet will achieve the counterclockwise rotation of the second rotating shaft. This avoids the fixation from loosening due to accidental reverse rotation, greatly improves the stability of the gearbox after fixation, and ensures reliable assembly.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

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.

[0028] Please see Figure 1-7 As shown, this utility model is a quick-fix installation structure for a gearbox, including a mounting base 111 and a gearbox 112 disposed on top of the mounting base 111, and further including: a fixing part 2, which is mounted on the mounting base 111; and an anti-reverse part 3, which is mounted on the fixing part 2. The mounting base 111 is composed of a base plate and an internally hollow rectangular frame, with the rectangular frame fixed to the upper surface of the base plate.

The drive assembly 21 is installed inside the mounting base 111, and the fixing assembly 22 is installed on the top of the mounting base 111 and connected to the drive assembly 21. The drive assembly 21 includes a first rotating shaft 211 rotatably connected between the inner top wall of the rectangular frame of the mounting base 111 and the bottom plate. A gear 212 is fixedly connected to the outer wall of the first rotating shaft 211. Two rectangular rings 213 are fixedly connected to the inner top wall of the rectangular frame of the mounting base 111 near the gear 212. Each of the two rectangular rings 213 has a rack 214 passing through the ring. Both racks 214 mesh with the gear 212. A second rotating shaft 215 is rotatably connected to the front side of the mounting base 111. The rear side of the second rotating shaft 215 extends into the mounting base 111. A transmission component is provided on the second rotating shaft 215. The two racks 214 are located in front of and behind the gear 212 and are staggered.

[0030] The transmission component includes bevel gears 216 that are fixedly connected to the outer walls of the first rotating shaft 211 and the second rotating shaft 215 respectively. The two bevel gears 216 mesh with each other, and a handle 217 is fixedly connected to the outer wall of the second rotating shaft 215. The two bevel gears 216 are both located inside the mounting base 111. The bevel gear 216 on the outer wall of the first rotating shaft 211 is located below the gear 212, and the handle 217 is located on the front side of the mounting base 111.

[0031] The fixing component 22 includes two limiting slide grooves 221 that are formed on the top of the rectangular frame of the mounting base 111 and extend in the left and right direction. The inner walls of the two limiting slide grooves 221 are slidably connected to sliders 222. The bottom of the two sliders 222 is fixedly connected to the ends of the two racks 214 away from the gears 212, respectively. The top of the two sliders 222 is fixedly connected to a fixing plate 223. The sides of the two fixing plates 223 that are close to each other are fixedly connected to an anti-slip buffer pad 224. The two sliders 222 are located on the top of the two racks 214 respectively.

[0032] By setting the fixing part 2, the operation difficulty is reduced, the technical requirements for operators are more relaxed, the installation deviation is reduced, the stability of the gearbox 112 assembly is ensured, and the labor and time costs are reduced.

[0033] The anti-reverse component 3 includes a support assembly 31 and a limiting assembly 32. The support assembly 31 is mounted on the mounting base 111, and the limiting assembly 32 is mounted on the second rotating shaft 215. The support assembly 31 includes a support plate 311 fixedly connected to the front side of the mounting base 111. A telescopic rod 312 is fixedly connected to the left side of the support plate 311, and a rectangular plate 313 is fixedly connected to the left side of the telescopic rod 312. An elastic element is provided on the telescopic rod 312. The support plate 311, the telescopic rod 312, and the rectangular plate 313 are all located on the right side of the second rotating shaft 215.

[0034] The elastic element includes a spring 314 sleeved on the outer wall of the telescopic rod 312. The left side of the spring 314 is fixedly connected to the rectangular plate 313, and the right side of the spring 314 is fixedly connected to the support plate 311. The spring 314 is located between the rectangular plate 313 and the support plate 311.

[0035] The limiting component 32 includes a ratchet 321 fixedly connected to the outer wall of the rotating shaft 215. A limiting block 322 is fixedly connected to the left side of the rectangular plate 313, and the limiting block 322 is adapted to the ratchet 321; wherein, the limiting block 322 is located on the right side of the ratchet 321. The two sides of the ratchet 321 teeth that mate with the limiting block 322 are a straight surface and an arc surface, respectively, and the straight surface of the limiting block 322 is in contact with the straight surface of the ratchet 321 teeth.

[0036] By setting the anti-reverse rotation part 3, the fixing is prevented from becoming loose due to accidental reverse rotation, which greatly improves the stability of the gearbox 112 after fixing and ensures reliable assembly.

[0037] In the quick-fixing and installation structure of the gearbox provided by this utility model, the rack is rigidly connected to the slider of the fixing component, and the slider drives the fixing plate to move. Because the sliding speed and displacement of the rack are completely consistent, the fixing plate will also move closer to the gearbox synchronously, ensuring that the fixing plates on both sides are fixed to the gearbox at the same time. In addition, the anti-slip buffer pad on the inner side of the fixing plate can increase the static friction with the gearbox, prevent slippage, and fill the gap to achieve surface contact. The anti-reverse part, through the cooperation of the ratchet and the limit block, can lock the reverse rotation of the drive component, prevent the clamping force from loosening due to accident, and further realize the stability of the fixing and clamping.

[0038] A specific application of this embodiment is as follows: During use, the gearbox 112 is placed on top of the mounting base 111. Then, the handle 217 is turned to rotate the second shaft 215 clockwise. At this time, the second shaft 215, through the action of two bevel gears 216, drives the first shaft 211 to rotate counterclockwise. The first shaft 211, through the gears 212, drives two racks 214 to slide and approach each other on corresponding rectangular rings 213. The two racks 214, through the gears 212, drive two sliders 222 to slide and approach each other within corresponding limiting grooves 221. The two sliders 222, through the two fixing plates 223, drive two anti-slip buffer pads 224 to fix the gearbox 112. Through the reverse operation process described above, the fixation of the gearbox 112 is released. When the second shaft 215 rotates clockwise, it drives the ratchet 321 to rotate clockwise. At this time, the ratchet 321… The rectangular plate 313 is pressed by the limiting block 322, causing the rectangular plate 313 to move the limiting block 322 to the right and away from the ratchet 321. During this process, the telescopic rod 312 and the spring 314 will be deformed by the compression, causing the spring 314 to generate elastic force. When the limiting block 322 corresponds to another groove on the ratchet 321, under the action of the spring 314, the rectangular plate 313 will cause the limiting block 322 to be inserted into the tooth groove of the ratchet 321 again, thereby repeatedly rotating the ratchet 321 clockwise. Under the action of the straight surface of the limiting block 322 and the straight surface of the ratchet 321, the counterclockwise rotation of the second shaft 215 can be restricted, preventing accidental reverse rotation. When it is necessary to rotate the second shaft 215 counterclockwise, the rectangular plate 313 is pulled to move the limiting block 322 away from the ratchet 321, and the second shaft 215 is rotated counterclockwise, which can release the fixation of the gearbox 112, and the gearbox 112 can be removed. The entire fixed installation structure is pre-fixed to the equipment frame or the ground through the bolt holes on the mounting base 111. The fixed installation structure always remains in its original position, waiting for the gearbox to be used again next time.
