Description

Technical Field

[0001] The utility model belongs to the technical field of concrete electric poles, and in particular relates to a transmission device for concrete electric poles. Background Art

[0002] Concrete utility poles are made of concrete and steel bars or wire, and include both regular utility poles and utility poles. Utility poles are generally 4.5 to 15 meters long, and their cross-sections include square, octagonal, I-shaped, circular, or other special-shaped shapes, with circular and square sections being the most commonly used.

[0003] Concrete utility poles require transmission during their production and handling. Patent application number CN201810410896.9 discloses a transmission device for concrete utility poles, comprising a frame with a horizontal conveying motor mounted on one side. A horizontal conveying roller, a vertical conveying mechanism, and an auxiliary clamping mechanism are mounted inside the frame, with both the vertical conveying mechanism and the auxiliary clamping mechanism located between the horizontal conveying rollers. Each of the horizontal conveying rollers is fixedly connected to the horizontal conveying motor, and a horizontal conveying sprocket is mounted on the end of the horizontal conveying roller. A horizontal conveying chain is engaged and mounted on the outer side of the horizontal conveying sprocket. This transmission device can apply transmission force to the utility poles on both sides, making it less prone to slippage. At the same time, the auxiliary clamping mechanism can clamp the utility poles, ensuring accurate transmission while limiting and guiding the poles. However, this transmission device can only transmit telephone poles within a specific diameter range, and its applicability is relatively small. In addition, if the clamping spring at the rear end of the clamping roller is not contracted in time, the front end of the telephone pole is likely to collide with the clamping roller, which will not only cause damage to the roller but also affect the transmission process of the telephone pole.

[0004] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art.

[0030] Refer to the attached Figure 1-4 A transmission device for a concrete utility pole includes a base 1 and a plurality of transmission units 2 located on the base 1; each transmission unit 2 includes:

[0031] Two mounting seats 3 are provided above the base 1; hinged ears 4 are provided on both sides of the top of the mounting seat 3, and a horizontal transmission roller 5 rotatably connected to the hinged ears 4 is provided between the two hinged ears 4;

[0032] Mounting seat 2 6, multiple vertically arranged between the two mounting seats 1 3; mounting seat 2 6 is provided with hinged ears 2 7 at both upper and lower ends, and a vertical transmission roller 8 rotatably connected to the two hinged ears 2 7 is provided between the two hinged ears 2;

[0033] Mounting seat three 9 is provided between two mounting seats one 3; a movable roller 10 is provided on the side of mounting seat three 9 facing the vertical transmission roller 8, and its bottom is rotatably connected to the two mounting seats one 3; a baffle 11 is provided on one side of the top of mounting seat three 9, and a shift lever 12 is provided on the other side;

[0034] The power plate 13 is located on one side of the base 1 and has a slide groove 14 in the middle thereof; two parallel slide rods 15 are provided inside the slide groove 14, and a slide seat 16 is provided on the slide rods 15 to slide with them; a compression spring 17 is also sleeved on the slide rod 15, and the compression spring 17 abuts against the side of the slide seat 16 away from the base 1;

[0035] The top of the support rod 18 is hinged on the mounting seat 3 9, and the bottom is hinged on the slide 16.

[0036] In this embodiment, the outermost layers of the horizontal transmission roller 5, the vertical transmission roller 8 and the movable roller 10 are made of rubber or plastic to prevent the surface of the concrete pole from being scratched. A plurality of avoidance grooves 19 are provided in the middle of the base 1, and the avoidance grooves 19 correspond to the bottom position of the mounting seat 3 9. A positioning shaft 20 is provided between the two mounting seats 1 3 of each transmission unit 2. The positioning shaft 20 passes through the bottom of the mounting seat 3 9 and rotates with the bottom of the mounting seat 3 9. When the concrete pole is being transported, the movable roller 10 contacts the outer wall of the concrete pole, causing the movable roller 10 to tilt toward the power assist plate 13. At this time, the bottom of the mounting seat 3 9 rotates with the positioning shaft 20 as the rotating axis. The avoidance grooves 19 provided in the base 1 are also to avoid blocking the rotation of the movable roller 10 and the mounting seat 3 9, so as to prevent the bottom of the movable roller 10 from touching the base 1 when adjusting the tilt angle.

[0037] In addition, a pad 21 is positioned between the two mounting brackets 1 and 3 of each transport unit 2; the bottom of the vertical transport roller 8 is fixed to the upper surface of the pad 21. Because the pad 21 has a certain height, the bottom of the vertical transport roller 8 does not fall too far below the horizontal transport roller 5. This allows for shorter horizontal transport rollers 5, reducing costs. The position of the vertical transport roller 8 remains unchanged; by adjusting the tilt angle of the movable roller 10, concrete poles of varying diameters can be transported. The two horizontal transport rollers 5 of each transport unit 2 are driven by a motor, belt, and pulley (not shown in the accompanying drawings) to rotate synchronously, thereby moving the concrete poles above them. This is prior art and will not be further described.

[0038] In actual use, when transporting concrete utility poles, the front end of the concrete utility pole needs to be placed on the transverse transmission roller 5; the transverse transmission roller 5 rotates continuously under the drive of the motor, belt and pulley, and can drive the concrete utility pole to move under the action of friction. When the front end of the concrete utility pole passes through the movable roller 10, its side contacts the movable roller 10, which can cause the movable roller 10 to rotate a certain angle. The application range of the concrete utility pole transmission device of the present invention is very wide. When concrete utility poles of different diameters are placed on the transverse transmission roller 5, the movable roller 10 will rotate to different angles, and drive the movable roller 10 of the subsequent transmission unit 2 to rotate synchronously by a certain angle, so as to smoothly transport the concrete utility pole.

[0039] It should be noted that, since the lever 12 on one side of the mounting seat three 9 is in abutment with the baffle 11 on the next mounting seat three 9, when the movable roller 10 rotates a certain angle, the first mounting seat three 9 will drive the next mounting seat three 9 to rotate synchronously by a certain angle, and the adjacent transmission units 2 also achieve consistent rotation angles through the cooperation of the lever 12 and the baffle 11, thereby avoiding the subsequent movable roller 10 and its mounting seat three 9 from colliding with the front end of the concrete pole, ensuring the smooth transmission of the concrete pole, and preventing the concrete pole from colliding and stopping transmission in the middle.

[0040] When the movable roller 10 contacts the concrete pole and rotates, it applies force to the support rod 18, forcing it toward the assist plate 13. At this point, the slide 16, hinged to the bottom of the support rod 18, moves along the slide rod 15, squeezing the compression spring 17. When the concrete pole is transported to the rear and the front conveyor unit 2 is no longer in contact with the pole, the movable roller 10 of the front conveyor unit 2 returns to its initial position under the thrust of the compression spring 17 and support rod 18, awaiting the arrival of the next concrete pole to continue the conveying operation.

[0041] The transmission device for concrete utility poles of the present invention is provided with a movable roller 10 and a mounting seat 3 9 with adjustable inclination angle, and cooperates with the slide 16 and the compression spring 17 on the support rod 18 and the power plate 13. When the movable roller 10 contacts the concrete utility pole, it can be adjusted to a suitable inclination angle, which is convenient for limiting concrete utility poles of different diameters and has a wide range of applications. At the same time, the movable roller 10 of the front transmission unit 2 can drive the movable roller 10 of the rear transmission unit 2 to tilt synchronously, which is convenient for continuous transmission of the concrete utility pole and solves the problem that the roller wheel of the existing transmission device may collide with the front end of the utility pole, affecting the transmission process. The utility pole is very practical and has good market application prospects.

[0042] The foregoing descriptions of specific exemplary embodiments of the present invention are for purposes of illustration and description. These descriptions are not intended to limit the present invention to the precise forms disclosed, and it is apparent that many modifications and variations are possible in light of the foregoing teachings. The exemplary embodiments have been selected and described for the purpose of explaining the specific principles of the present invention and their practical application, thereby enabling those skilled in the art to realize and utilize a variety of exemplary embodiments of the present invention and various options and variations.
