Description

Technical Field

[0001] This utility model relates to the field of speed reducer technology, and in particular to a horizontal tank speed reducer. Background Technology

[0002] The integrated mixer-pump truck is a product that combines a cement mixer truck and a pump truck, integrating the functions of walking, cement mixing and pumping. The main market for this product is Europe and the United States, and there are OEM companies in China. Currently, the mixing tank of this product on the market operates at an angle. Due to height restrictions, the boom and pipeline can only be installed on one side of the vehicle, which results in poor balance of the vehicle when not in operation.

[0003] The speed reducer is usually located at an angle in the mixing tank, which makes it difficult for the lubricating oil to evenly cover the gears and bearings. Especially when the vehicle is moving or operating, the lubricating oil tends to concentrate on one side of the speed reducer, and gravity causes the lubricating oil to drip directly onto the housing, preventing it from making sufficient contact with the internal parts of the speed reducer. This results in dry friction inside the speed reducer, causing insufficient lubrication. Utility Model Content

[0004] The purpose of this utility model is to provide a flat-mounted tank reducer in order to solve the problem that existing lubricating oil is difficult to evenly cover gears and bearings.

[0005] To achieve the above objectives, the present invention employs the following technology: a horizontally mounted tank reducer, comprising a transport vehicle and a mixing tank rotatably mounted on the transport vehicle, wherein the transport vehicle is equipped with a reduction gear assembly capable of controlling the rotational speed of the mixing tank; The deceleration assembly includes a connecting rod fixedly installed on the mixing tank, a gear ring and a housing fixedly installed on the mixing tank and the transport vehicle respectively, a servo motor fixedly installed on one side of the housing, a rotating component capable of driving the mixing tank to rotate, and a lubrication assembly for lubricating the rotating component.

[0006] As a further description of the above technical solution: the rotating component includes a worm gear and a rotating rod rotatably mounted on the chassis, a worm wheel is fixedly mounted on the rotating rod, and a gear is fixedly mounted on one end of the rotating rod extending to the outside of the chassis.

[0007] As a further description of the above technical solution: the worm gear meshes with the worm wheel, and one end of the worm gear extending to the outside of the chassis is fixedly connected to the output end of the servo motor, and the gear meshes with the gear ring.

[0008] As a further description of the above technical solution: the lubrication assembly includes an oil box fixedly installed on the chassis, several oil drip pipes connected and installed on the oil box, an oil tank fixedly installed on one side of the transport vehicle, and a delivery pipe arranged between the chassis and the oil tank.

[0009] As a further description of the above technical solution: an oil pump is fixedly installed on the transport vehicle, and there are two delivery pipes, one of which is connected to the engine box and the oil outlet of the oil pump, and the other is connected to the oil inlet of the oil pump and the oil tank.

[0010] As a further description of the above technical solution: the chassis is also equipped with a collection component; The collection component includes a collection box placed at the bottom of the chassis, a cone-shaped block one and a cone-shaped block two set on the collection box by a fixing rod, a number of mounting brackets fixedly installed on the chassis, and a limiting block set on the mounting bracket by a spring.

[0011] As a further description of the above technical solution: the second conical block is slidably mounted on the fixed rod, the limiting block is located between the first conical block and the second conical block, and one side of the limiting block is set as an inclined surface.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: By utilizing the combination of worm gear and worm wheel, and gear and gear ring, the rotational speed is significantly reduced while the torque is amplified. This reduces the centrifugal force of concrete during low-speed operation of the mixing tank, preventing splashing and accumulation. At the same time, the high torque can handle the viscous and heavy characteristics of concrete, improving mixing uniformity and efficiency. The lubrication component ensures that components such as the worm gear and worm wheel are adequately lubricated. Combined with the horizontally placed mixing tank, it solves the problem of uneven lubrication caused by tilting operations, extends the life of components, and the lubricating oil is recycled, saving resources and reducing pollution. The collection component can collect and store oil stains and impurities generated by lubricating oil dripping, preventing them from accumulating in the machine casing and interfering with the normal operation of transmission components, reducing the failure rate. With the help of the conical block and limit block, the replacement and maintenance of the collection box can be completed quickly. Attached Figure Description

[0015] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0016] Reference Figure 1 - Figure 6 The embodiment provides a horizontal tank reducer, including a transport vehicle 10 and a mixing tank 11 rotatably mounted on the transport vehicle 10. The mixing tank 11 is horizontally placed on the transport vehicle 10, and the transport vehicle 10 is equipped with a reduction assembly 20 that can control the rotational speed of the mixing tank 11. The deceleration assembly 20 includes a connecting rod 21 fixedly installed on the mixing tank 11, a gear ring 22 and a housing 23 fixedly installed on the mixing tank 11 and the transport vehicle 10 respectively, a servo motor 24 fixedly installed on one side of the housing 23, a rotating component 25 that can drive the mixing tank 11 to rotate, and a lubrication assembly 30 that lubricates the rotating component 25.

[0017] Reference Figure 2 - Figure 3 Specifically, in order to drive the mixing tank 11 to rotate, the rotating component 25 includes a worm gear 251 and a rotating rod 252 rotatably mounted on the housing 23. A worm wheel 253 is fixedly mounted on the rotating rod 252, and a gear 254 is fixedly mounted on one end of the rotating rod 252 extending to the outside of the housing 23. The worm wheel 253 and the gear 254 can rotate through the rotating rod 252.

[0018] In more detail, the worm 251 meshes with the worm wheel 253. When the worm 251 rotates, the meshing causes the worm wheel 253 to rotate via the rotating rod 252. The end of the worm 251 extending to the outside of the housing 23 is fixedly connected to the output end of the servo motor 24. The servo motor 24 can drive the worm 251 to rotate. The gear 254 meshes with the gear ring 22. By starting the servo motor 24, the worm 251 can be driven to rotate. The meshing causes the worm wheel 253 to rotate via the rotating rod 252, which in turn drives the gear 254 to rotate. The meshing causes the gear ring 22 to drive the connecting rod 21 to rotate, thereby enabling the mixing tank 11 to rotate. Servo motor 24 drives worm gear 253 to rotate, achieving initial deceleration and direction change. Worm 251 and worm gear 253 mesh. Due to the small number of teeth in worm 251 and the large number of teeth in worm gear 253, the speed ratio is large, and the torque increases accordingly, completing the initial deceleration. At the same time, the axis of worm 251 is perpendicular to the axis of worm gear 253, changing the direction of power transmission. Worm gear 253 drives rotating rod 252 to rotate, transmitting power to gear 254. Gear 254 meshes with gear ring 22. Gear ring 22 has a large number of teeth, further reducing the speed and increasing the torque. Finally, connecting rod 21 transmits low-speed, high-torque power to mixing tank 11 through gear ring 22, meeting its low-speed, high-torque mixing requirements.

[0019] Reference Figure 2 - Figure 3 Specifically, in order to lubricate the worm 251 and worm wheel 253, a lubrication assembly 30 is provided. The lubrication assembly 30 includes an oil box 31 fixedly installed on the housing 23, several oil drip pipes 32 connected and installed on the oil box 31, and an electrically controlled valve is provided on the oil drip pipes 32. An oil tank 33 is fixedly installed on one side of the transport vehicle 10. The oil tank 33 stores lubricating oil inside, and a delivery pipe 34 is provided between the housing 23 and the oil tank 33.

[0020] In more detail, an oil pump 35 is fixedly installed on the transport vehicle 10. There are two delivery pipes 34. One of them is connected to the oil outlet of the engine box 23 and the oil pump 35, and the other is connected to the oil inlet of the oil pump 35 and the oil tank 33. By starting the oil pump 35, the lubricating oil inside the oil tank 33 can be delivered through the delivery pipe 34. The delivery through the delivery pipe 34 allows the lubricating oil to fill the oil box 31. At this time, the electronic control valve is in the closed state, and the lubricating oil inside the oil box 31 cannot be discharged through the drip pipe 32. When lubrication of the worm 251 and worm wheel 253 is required, the lubricating oil inside the oil box 31 is dripped onto the worm 251 through the oil drip pipe 32 by opening the electronically controlled valve. The rotating worm 251 allows the lubricating oil to be evenly covered on the surface of the worm 251 and worm wheel 253, thus achieving a lubrication effect.

[0021] Specifically, in order to collect the spilled oil, a collection component 36 is also installed on the chassis 23; Reference Figure 4 - Figure 6 The collecting component 36 includes a collecting box 361 placed at the bottom of the chassis 23. The collecting box 361 collects oil stains and other impurities generated when the worm gear 251 and worm wheel 253 rotate. Conical block 1 362 and conical block 2 363 are set on the collecting box 361 by a fixing rod 364. Several mounting brackets 365 are fixedly installed on the chassis 23. Limiting blocks 366 are set on the mounting brackets 365 by springs 367. The limiting blocks 366 are symmetrically arranged on the mounting brackets 365 by springs 367. The reaction force of the springs 367 enables the limiting blocks 366 to reset.

[0022] In more detail, the second conical block 363 is slidably mounted on the fixed rod 364. The second conical block 363 can slide on the fixed rod 364. The limiting block 366 is located between the first conical block 362 and the second conical block 363. The limiting block 366 plays a limiting role on the first conical block 362, thereby installing the collection box 361 on the housing 23. One side of the limiting block 366 is set as an inclined surface. When the collection box 361 needs to be removed for cleaning, pushing the collection box 361 upwards causes the fixing rod 364 to rise, which in turn causes the conical block 362 and conical block 363 to rise. As conical block 363 rises, the inclined surface of the side of the limiting block 366 contacts the inclined surface of conical block 363. The rising conical block 363 exerts a squeezing effect on the limiting block 366, causing the limiting blocks 366 on both sides to retract inwards towards the mounting bracket 365. Simultaneously, the reaction force of the spring 367 causes the limiting block 366 to also make tight contact with the surface of conical block 363, thus clamping conical block 363. Figure 6 As shown, by pulling the collection box 361 downward, the fixing rod 364 causes the cone block 362 to descend. Since the cone block 363 is clamped and limited at this time, it will not move, so the descending cone block 362 can fit with the cone block 363. The descending cone block 362 causes the cone block 363 to descend, and at this time the limiting block 366 will contact the inclined surface on the cone block 362 through the reaction force of the spring 367 until the cone block 362 is removed from the mounting bracket 365, thus completing the disassembly of the collection box 361. When it is necessary to install the collection box 361, simply place the collection box 361 at the bottom of the chassis 23 and push the collection box 361 upwards, so that the rising conical block 362 presses against the inclined surfaces of the two limiting blocks 366, causing it to retract. Figure 5As shown, the reaction force of the spring 367 then allows the limiting block 366 to reset and be positioned between the first conical block 362 and the second conical block 363. At the same time, the top of the limiting block 366 will also contact the bottom of the first conical block 362, thereby playing a role in bearing and limiting the first conical block 362, thus completing the installation of the collection box 361.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
