Description

Technical Field

[0001] This utility model belongs to the field of utility pole recycling technology, and in particular relates to a utility pole cutting and unloading device. Background Technology

[0002] With the advancement of power system upgrades and renovations, a large number of long-serving concrete power poles face the need for rebar cutting and rebar dismantling. In existing technologies, the pre-treatment stage of the connection between the rebar and the concrete substrate generally involves manual hand-held cutting equipment for cement cleaning.

[0003] The following technical bottlenecks urgently need to be addressed: manual cutting is easily affected by the operator's skill level, and uneven cuts can hinder subsequent unloading processes. Traditional manual cutting results in large errors in the cross-sectional tilt, which seriously affects the integrity of the disassembly of the tray. Cutting operations must be carried out in narrow spaces, posing risks of injury from flying debris and equipment collisions. Pre-processing for manual cutting of a single utility pole is time-consuming and requires frequent shift changes, making it difficult to meet the needs of large-scale renovation.

[0004] To address these issues, we provide a pole cutting and unloading device. Utility Model Content

[0005] The purpose of this utility model is to provide a pole cutting and unloading device. By combining the axial adjustment component and the angle adjustment component, it solves the problems of low cutting accuracy and low operating efficiency of existing pole cutting and unloading devices.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a pole cutting and unloading device, comprising a guide rail, an unloading mechanism on one side of the top of the guide rail, and a support platform on the other side of the top of the guide rail; an axial adjustment assembly is provided on one side of the support platform, the axial adjustment assembly comprising a hydraulic telescopic cylinder fixedly connected to the top of the support platform, a support plate fixedly connected to the telescopic end of the hydraulic telescopic cylinder, a movable plate disposed on the top of the support plate, a groove formed on one side of the movable plate, and a mounting plate movably connected to the inner cavity of the groove via a rotating shaft; an angle adjustment assembly is provided on the top of the movable plate, the angle adjustment assembly comprising a housing fixedly connected to the top of the movable plate, a servo motor fixedly connected to the inner cavity of the housing, a threaded rod fixedly connected to the output shaft of the servo motor, a threaded sleeve threadedly connected to the surface of the threaded rod, a limiting rod fixedly connected to the surface of the threaded sleeve, and an adjusting rod movably connected to one end of the limiting rod.

[0008] The present invention is further configured such that a drive motor is fixedly connected to the front side of the support plate, a gear is fixedly connected to the output shaft of the drive motor, and a toothed plate meshes with the surface of the gear. The drive motor forms a precision rack and pinion transmission system through the gear and the toothed plate, which has higher positioning accuracy than the traditional lead screw transmission.

[0009] The present invention is further configured such that a fixing groove is provided on the front side of the movable plate, and one side of the toothed plate is fixedly connected to the inner cavity of the fixing groove. The fixing groove prevents the toothed plate from protruding outward and protects the toothed plate.

[0010] The present invention is further configured such that a slide rail is fixedly connected to the bottom of the movable plate, and a slide groove is slidably connected to the bottom of the slide rail. The slide groove is formed on the top of the support plate. The slide rail and the slide groove cooperate to ensure movement stability and low repeatability error.

[0011] The present invention is further configured such that the other end of the limiting rod extends through to the outside of the chassis and is movably connected to one end of the adjusting rod. A limiting groove adapted to the limiting rod is provided on one side of the chassis. The limiting rod and the limiting groove cooperate to facilitate the limiting of the threaded sleeve and improve the stability of the axial movement of the threaded sleeve.

[0012] The present invention is further configured such that there are three adjusting rods, and the other ends of the three adjusting rods are movably connected to one side of the mounting plate. The three-point support structure makes the mounting plate bear force evenly, reduces local stress, and avoids single-point deformation.

[0013] The present invention is further configured such that a cutting component is fixedly connected to one side of the mounting plate, and a support mechanism is provided on the top of the support platform.

[0014] The present invention has the following beneficial effects.

[0015] 1. This utility model achieves digital programming of the cutting trajectory through the linkage control of the axial adjustment component and the angle adjustment component. The servo motor drives the threaded rod to make fine-tuning of the angle, and with the rigid support of the three-point adjustment rod, the cutting plane and the tangent of the steel bar are precisely formed at the optimal cutting angle of 15 degrees, thereby improving processing efficiency.

[0016] 2. This utility model combines a gear and rack transmission mechanism with a dual-oil hydraulic system to enable the cutting component to be positioned quickly in three axes with high repeatability. During the cutting process, the support mechanism synchronously drives the pole to rotate, and together with the intelligent unloading assembly, it realizes continuous cutting and unloading operations.

[0017] 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

[0026] Example 1

[0027] Please see Figures 1-5This utility model is a device for cutting and unloading rebar on utility poles, including a guide rail 1, an unloading mechanism 2 on one side of the top of the guide rail 1, and a support platform 3 on the other side of the top of the guide rail 1; an axial adjustment assembly is provided on one side of the support platform 3, the axial adjustment assembly includes a hydraulic telescopic cylinder 4 fixedly connected to the top of the support platform 3, a support plate 5 fixedly connected to the telescopic end of the hydraulic telescopic cylinder 4, a movable plate 6 on the top of the support plate 5, a groove 7 on one side of the movable plate 6, and a mounting plate 8 movably connected to the inner cavity of the groove 7 via a rotating shaft; an angle adjustment assembly is provided on the top of the movable plate 6, the angle adjustment assembly includes a housing 9 fixedly connected to the top of the movable plate 6, a servo motor 10 fixedly connected to the inner cavity of the housing 9, a threaded rod 11 fixedly connected to the output shaft of the servo motor 10, a threaded sleeve 12 threadedly connected to the surface of the threaded rod 11, a limiting rod 13 fixedly connected to the surface of the threaded sleeve 12, and an adjusting rod 14 movably connected to one end of the limiting rod 13.

[0028] Further details: The unloading mechanism 2 is existing technology and will not be described in detail in this utility model. The guide rail 1 adopts a segmented and splicable design. Adjacent guide rails 1 are connected by dovetail grooves to achieve length expansion to adapt to different specifications of utility poles. The hydraulic telescopic cylinder 4 adopts a dual-oil-circuit synchronous hydraulic system. The two sets of cylinders are symmetrically arranged on both sides of the bottom of the support plate 5 to ensure no deviation during the lifting process. At the same time, it can adapt to the position adjustment of steel bars with different diameters. A ball joint is set at the connection between the adjusting rod 14 and the mounting plate 8 to allow small-amplitude swing angle compensation. The threaded rod 11 works with the self-locking threaded sleeve 12 to achieve precise angle positioning.

[0029] Example 2

[0030] Please see Figures 1-5 Based on embodiment 1, a drive motor 15 is fixedly connected to the front of the support plate 5, a gear 16 is fixedly connected to the output shaft of the drive motor 15, a toothed plate 17 meshes with the surface of the gear 16, a fixed groove 18 is opened on the front of the moving plate 6, one side of the toothed plate 17 is fixedly connected to the inner cavity of the fixed groove 18, a slide rail 19 is fixedly connected to the bottom of the moving plate 6, a slide groove 20 is slidably connected to the bottom of the slide rail 19, the slide groove 20 is opened at the top of the support plate 5, the other end of the limiting rod 13 passes through to the outside of the housing 9 and is movably connected to one end of the adjusting rod 14, a limiting groove 21 adapted to the limiting rod 13 is opened on one side of the housing 9, there are three adjusting rods 14, the other ends of the three adjusting rods 14 are movably connected to one side of the mounting plate 8, a cutting component 22 is fixedly connected to one side of the mounting plate 8, and a support mechanism 23 is provided on the top of the support platform 3.

[0031] Further details: The drive motor 15 forms a precision rack and pinion transmission system with the gear 16 and the toothed plate 17. Compared with the traditional screw drive, it has high positioning accuracy. The fixed groove 18 prevents the toothed plate 17 from protruding outward and protects the toothed plate 17. The slide rail 19 and the slide groove 20 cooperate to ensure movement stability and low repeatability error. The limit rod 13 and the limit groove 21 cooperate to facilitate the limiting of the threaded sleeve 12 and improve the stability of the axial movement of the threaded sleeve 12. The three-point support structure makes the mounting plate 8 uniformly stressed, reduces local stress, and avoids single-point deformation. The support mechanism 23 (existing technology) mainly supports and limits the utility pole.

[0032] The working principle of this utility model is as follows: the output shaft of the drive motor 15 drives the toothed plate 17 through the gear 16, so that the moving plate 6 moves forward along the slide rail 19 to the cutting position. Then, the hydraulic telescopic cylinder 4 pushes the support plate 5 to rise to the working height. The servo motor 10 drives the threaded rod 11 to rotate, and the threaded sleeve 12 drives the limit rod 13 to move linearly. The three adjusting rods 14 are linked to change the tilt angle of the mounting plate 8 so that the cutting plane forms a 15-degree optimal cutting angle with the tangent of the utility pole. The cutting component 22 cuts the utility pole. The support component can drive the utility pole to rotate, and cooperate with the cutting component 22 to achieve circumferential cutting. After the circumferential cutting is completed, the unloading mechanism 2 clamps the steel bar disc and then applies a thrust to separate the disc.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
