Description

Technical Field

[0001] This utility model relates to the field of cement pole production technology, and in particular to a cement pole centrifugal device. Background Technology

[0002] Cement poles are primarily composed of steel bars and concrete, hence they are also known as reinforced concrete cement poles. They are mainly used as overhead power line supports in industries such as power, telecommunications, railways, and petroleum. A cement pole centrifugal device is a piece of equipment that uses centrifugal force to produce cement poles. When the centrifugal device is activated, the concrete mixture within the mold is subjected to centrifugal force, causing the concrete particles to assemble more closely, reducing porosity, and thus increasing the density and strength of the concrete, ultimately forming a cement pole.

[0003] A Chinese utility model patent (publication number: CN220446778U) discloses a high-efficiency centrifugal device for forming high-strength conical cement poles. The device loads a centrifugal drum onto a lifting device by hoisting, then controls the centrifugal drum to fall by the lifting device, so that the drive ring on the outside of the centrifugal drum fits with the transmission wheel. Finally, the centrifugal drum is rotated by a servo motor, thereby realizing the production of cement poles. However, during the loading of the centrifugal drum, the axial position of the drum can shift due to the difficulty in ensuring hoisting accuracy. Therefore, when the lifting device lowers the centrifugal drum, the drive ring and transmission wheel cannot achieve precise alignment, requiring the centrifugal drum to be re-hoisted and adjusted. This complex operation reduces production efficiency. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to propose a cement pole centrifuge device, which uses a linear module to drive a slide table to slide on a guide rail. The slide table drives the connecting shaft and the transmission wheel to move axially, thereby achieving accurate alignment between the transmission wheel and the drive ring on the centrifuge drum. This avoids the problem of repeated adjustments caused by insufficient hoisting accuracy, significantly improving production efficiency. Moreover, the braking assembly effectively prevents positional deviation caused by equipment vibration, ensuring the stability of the centrifuge drum during rotation.

[0006] To achieve the above objectives, this utility model proposes a cement pole centrifuge device, comprising a base, a drive motor, two lifting platforms, a centrifugal drum, a position adjustment mechanism, and a brake assembly. The two lifting platforms are symmetrically arranged on the base. The drive motor is mounted on the base and drives the position adjustment mechanism to rotate synchronously. The centrifugal drum is mounted on the position adjustment mechanism. The brake assembly is mounted on the base and connected to the position adjustment mechanism. The position adjustment mechanism includes a transmission assembly and a drive assembly. The transmission assembly is rotatably mounted on the base, and the drive assembly is mounted on the base and rotatably connected to the transmission assembly.

[0007] In addition, the cement pole centrifuge device proposed above according to this utility model may also have the following additional technical features: Specifically, the transmission assembly includes a transmission shaft, a spline groove, an internal spline, a transmission wheel, and a connecting shaft. The spline groove is disposed on the outer wall of the transmission shaft. There are two connecting shafts. The internal splines are symmetrically disposed at both ends of one of the connecting shafts and mesh with the spline groove. The connecting shaft connected to the internal spline is sleeved on the outside of the transmission shaft. The transmission wheel is symmetrically disposed at both ends of the two connecting shafts.

[0008] Specifically, the drive assembly includes two guide rails, a linear module, and a slide table, wherein the slide table is slidably disposed on the outer wall of the two guide rails, and the slider on the linear module is connected to the slide table.

[0009] Specifically, the brake assembly includes a brake pad, two friction pads, a brake seat, and a double-ended lead screw. The brake seat is sleeved on the outside of the brake pad. The two friction pads are symmetrically arranged on both sides of the brake pad and threaded to the outer wall of the double-ended lead screw. The double-ended lead screw is rotatably disposed inside the brake seat, and one end extends to the outside of the brake seat.

[0010] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects: This invention uses a linear module to drive a slide table to slide on a guide rail. The slide table drives the connecting shaft and the transmission wheel to move axially, thereby achieving accurate alignment between the transmission wheel and the drive ring on the centrifugal drum. This avoids repeated adjustments caused by insufficient hoisting accuracy and significantly improves production efficiency. After the centrifugal drum is loaded, a double-ended screw drives two friction plates and brake plates to fit tightly together. The friction force limits the position of the slide table, thereby ensuring the fixed position of the transmission wheel and preventing positional deviation due to equipment vibration, thus ensuring the stability of the centrifugal drum during rotation.

[0014] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0015] The following describes the cement pole centrifuge device according to an embodiment of the present invention with reference to the accompanying drawings.

[0016] like Figures 1-5 As shown, a cement pole centrifugal device according to an embodiment of the present invention includes a base 1, a drive motor 2, two lifting platforms 3, a centrifugal drum 4, a position adjustment mechanism and a brake assembly 7, wherein the two lifting platforms 3 are symmetrically arranged on the base 1, and the centrifugal drum 4 is arranged on the position adjustment mechanism. It should be noted that the lifting platform of the elevator 3 is equipped with a support component that can support the centrifugal drum 4. When the centrifugal drum 4 is placed on the support component, it can limit the centrifugal drum 4. A drive ring is fixedly installed on the centrifugal drum 4 for docking with the position adjustment mechanism. The interior of the centrifugal drum 4 is filled with cement rod material, and the exterior of the centrifugal drum 4 is provided with side columns to connect with the load-bearing components on the elevator 3. It is understandable that by using two lifting platforms 3 to move the centrifugal drum 4 downward, the drive ring on the centrifugal drum 4 can be connected to the position adjustment mechanism; The drive motor 2 is mounted on the base 1 and drives the position adjustment mechanism to rotate synchronously; It should be noted that the drive motor 2 is connected to the position adjustment structure through a transmission belt, which transmits power to the position adjustment mechanism, thereby driving the centrifugal drum 4 to rotate. The centrifugal force is used to make the concrete particles tightly arranged, which improves the density and strength of the cement rod.

[0017] Brake assembly 7 is mounted on base 1 and connected to position adjustment mechanism; It should be noted that the brake assembly 7 is used to limit the position of the position adjustment mechanism. During centrifugation, it can ensure that the position adjustment mechanism remains stable in the set position, preventing position deviation caused by equipment vibration, thereby ensuring the stability of the centrifugal drum 4 during rotation.

[0018] The position adjustment mechanism includes a transmission component 5 and a drive component 6, wherein the transmission component 5 is rotatably mounted on the base 1, and the drive component 6 is mounted on the base 1 and rotatably connected to the transmission component 5. It should be noted that the position adjustment mechanism can slide along the axial position of the centrifugal drum 4. When the centrifugal drum 4 deviates axially during hoisting, the drive component 6 drives the transmission component 5 to slide axially, thereby aligning the transmission component 5 with the drive ring on the centrifugal drum 4. This ensures that the drive ring and the transmission component 5 are accurately aligned, thus avoiding the problem of repeated adjustments due to insufficient hoisting accuracy and significantly improving production efficiency.

[0019] In one embodiment of this utility model, such as Figure 3 As shown, the transmission assembly 5 includes a transmission shaft 51, a spline groove 52, an inner spline 53, a transmission wheel 54, and a connecting shaft 55. The spline groove 52 is provided on the outer wall of the transmission shaft 51. There are two connecting shafts 55. The inner splines 53 are symmetrically arranged at both ends of one connecting shaft 55 and mesh with the spline groove 52. The connecting shaft 55 with the inner splines 53 is sleeved on the outside of the transmission shaft 51 and is slidably connected to the transmission shaft 51 through a linear bearing. The transmission wheel 54 is symmetrically arranged at both ends of the two connecting shafts 55. It should be noted that the drive shaft 51 is rotatably mounted on the base 1 via a bearing seat. Both the drive shaft 51 and the drive motor 2 are equipped with pulleys, which are connected by a transmission belt. Thus, when the drive motor 2 is working, it can drive the drive shaft 51 to rotate synchronously. The internal spline 53 is fixedly mounted on the connecting shaft 55 and communicates with the connecting shaft 55. The spline groove 52 meshes with the internal spline 53, ensuring the stability of power transmission between the transmission shaft 51 and the connecting shaft 55 and avoiding transmission failure caused by vibration. By adopting this connection method, the transmission efficiency can still be ensured to remain unaffected when the connecting shaft 55 slides outside the transmission shaft 51. The drive wheel 54 is rotatably mounted at both ends of the connecting shaft 55 via bearings, and its size is adapted to the size of the drive ring on the centrifugal drum 4, thereby enabling power transmission.

[0020] Specifically, during the transmission process, the drive ring on the centrifugal drum 4 contacts the corresponding four transmission wheels 54. The drive motor 2 synchronously drives the transmission shaft 51 to rotate through the transmission belt. With the cooperation of the spline groove 52 and the inner spline 53, the transmission shaft 51 drives a connecting shaft 55 to rotate. This connecting shaft 55 drives two transmission wheels 54, and the transmission wheels 54 drive the centrifugal drum 4, thereby enabling the centrifugal drum 4 to rotate and thus realize the smooth operation of the cement pole centrifugation.

[0021] In one embodiment of this utility model, such as Figure 3 As shown, the drive assembly 6 includes two guide rails 61, a linear module 62 and a slide table 63, wherein the slide table 63 is slidably disposed on the outer wall of the two guide rails 61, and the slider on the linear module 62 is connected to the slide table 63. It should be noted that the two guide rails 61 are arranged in parallel on the base 1, and the bottom of the slide table 63 is provided with a slide block, and the slide table 63 slides on the guide rails 61 through the slide block; Driven by the linear module 62, the sliding position of the slide table 63 on the guide rail 61 can be controlled. The slide table 63 is rotatably connected to the connecting shaft 55 through the bearing seat. When the slide table 63 slides, it will drive the connecting shaft 55 and the transmission wheel 54 to move axially, thereby aligning the transmission wheel 54 with the centrifugal drum 4.

[0022] Specifically, when the drive ring of the centrifugal drum 4 is not aligned with the transmission wheel 54, the linear module 62 is activated. The linear module 62 drives the slide table 63 to slide on the guide rail 61. The slide table 63 drives the connecting shaft 55 and the transmission wheel 54 to move axially. When the transmission wheel 54 is accurately aligned with the drive ring on the centrifugal drum 4, the linear module 62 stops. Then, the elevator 3 drives the centrifugal drum 4 to move downward so that its drive ring aligns with the transmission wheel 54, thereby completing the loading of the centrifugal drum 4.

[0023] In one embodiment of this utility model, such as Figure 5 As shown, the brake assembly 7 includes a brake pad 71, two friction pads 72, a brake seat 73, and a double-ended screw 74. The brake seat 73 is sleeved on the outside of the brake pad 71. The two friction pads 72 are symmetrically arranged on both sides of the brake pad 71 and are threaded to the outer wall of the double-ended screw 74. The double-ended screw 74 is rotatably disposed inside the brake seat 73, and one end extends to the outside of the brake seat 73. It should be noted that the brake pad 71 is fixedly mounted on the base 1, the brake seat 73 is fixedly mounted on the slide table 63, and the opposite surface of the friction pad 72 is provided with abrasive particles, which can increase the friction between the friction pad 72 and the brake pad 71. Specifically, after the position of the transmission wheel 54 is adjusted, the double-ended lead screw 74 is rotated clockwise. The double-ended lead screw 74 drives the two friction plates 72 to move towards the brake plate 71, so that the two friction plates 72 and the brake plate 71 are in close contact. The position of the slide table 63 is limited by friction, thereby ensuring that the position of the transmission wheel 54 is fixed, preventing the position from shifting due to equipment vibration, and ensuring the stability of the centrifugal drum 4 when rotating. When the position of the drive wheel 54 needs to be adjusted, the double-ended lead screw 74 is rotated counterclockwise to separate the friction plate 72 from the brake plate 71. The position limitation of the slide 63 is released, and the position of the drive wheel 54 can be adjusted to achieve accurate alignment between the drive wheel 54 and the drive ring on the centrifugal drum 4.

[0024] In summary, the cement pole centrifuge device of this utility model, by setting a position adjustment mechanism, can adjust the position of the transmission wheel, achieving accurate alignment between the transmission wheel and the drive ring on the centrifuge drum. This avoids the problem of repeated adjustments caused by insufficient hoisting accuracy, significantly improving production efficiency. At the same time, after the position of the slide is adjusted, the double-ended lead screw drives two friction plates and brake plates to fit tightly together, using friction to limit the position of the slide, thereby ensuring the fixed position of the transmission wheel and preventing positional deviation caused by equipment vibration. This ensures the stability of the centrifuge drum during rotation and further guarantees the smooth operation of cement pole centrifugation.
