Description

Technical Field

[0001] This utility model relates to the field of power pole production and processing technology, and in particular to a pole mold oiling device for power pole production. Background Technology

[0002] During the production of cement utility poles, before placing the steel reinforcement cage into the pole mold, an oil-based release agent needs to be applied to the inner wall of the mold to form an isolation layer between the cement utility pole and the mold. This makes it easier for the utility pole to be removed from the mold after molding, prevents the concrete from sticking to the mold, ensures a smooth surface for the utility pole, and avoids damage to the appearance and structural integrity of the mold and the utility pole.

[0003] Some existing technologies use an arc-shaped brush that matches the curvature of the pole mold for oiling. The arc-shaped brush is then moved along the axis of the pole mold to replace manual oiling of each section of the pole mold. Although the uniformity of oiling is high, different arc-shaped brushes need to be used for different specifications of utility poles. Or for some conical non-uniform diameter utility poles, the diameter gradually changes, and a brush with a fixed curvature cannot be used for precise oiling. For example, when the arc-shaped brush moves to the pole mold at the smaller diameter end, it may get stuck and the oiling operation cannot continue.

[0004] Based on the above situation, we propose a pole mold oiling device for electric pole production to solve the above problems. Utility Model Content

[0005] This invention provides a pole mold oiling device for electric pole production, which solves the problem in the prior art that it cannot adapt to changes in pole mold diameter for oiling.

[0006] The technical problem solved by this utility model is achieved by the following technical solution:

[0007] A pole mold oiling device for electric pole production includes a bendable elastic arc-shaped component, a crossbeam, and an injection mechanism. The outer wall of the elastic arc-shaped component is provided with a flexible coating for contacting the inner wall of the pole mold, and the interior of the elastic arc-shaped component has a receiving cavity for holding release fluid to wet the flexible coating. Two displacement components are slidably connected to the crossbeam, and the two displacement components are respectively fixedly connected to both ends of the elastic arc-shaped component. When the curvature of the elastic arc-shaped component changes with the inner diameter of the pole mold, it drives the displacement components to move synchronously. The output end of the injection mechanism is connected to the displacement components for injecting release fluid into the receiving cavity.

[0008] Preferably, the filling mechanism includes a container mounted on a crossbeam, a hose connected to the bottom of the container, the hose being fixedly connected to a displacement member and having its output end extending into the interior of the container cavity, and a valve being provided on the hose.

[0009] Preferably, a pressure rod is threadedly connected to the crossbar, and the bottom end of the pressure rod is aligned with the valley point of the elastic arc-shaped member to limit the elastic arc-shaped member.

[0010] Preferably, the pressure bar includes a first connecting part and a second connecting part, and the first connecting part and the second connecting part are connected by a spring.

[0011] Preferably, the two ends of the crossbar are connected to retractable support members, and the bottom end of the retractable support member is connected to a caster wheel.

[0012] Preferably, the flexible coating and the elastic arc-shaped component are detachably connected.

[0013] The beneficial effects of this utility model are: by using an adjustable elastic arc-shaped component, when applying release liquid along the axial direction of the rod mold, it can change synchronously with the change of the rod mold diameter to fit the inner wall surface of the rod mold, thereby driving the flexible coating component to always fit tightly against the inner wall of the rod mold, avoiding uneven oiling or missed coating problems caused by poor fit, and also adapting to rod molds of different specifications and models, making its application range wider.

Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0021] Reference Figures 1-4 As shown, a pole mold oiling device for electric pole production includes a bendable elastic arc-shaped component 1. The elastic arc-shaped component 1 can be made of an elastic material such as rubber that can deform under force. A flexible coating component 2 is provided on the outer wall of the elastic arc-shaped component 1, and a receiving cavity 21 for holding release fluid is opened inside the elastic arc-shaped component 1 for wetting the flexible coating component 2. The flexible coating component 2 can be made of a material such as cotton cloth. When the release fluid in the receiving cavity 21 wets the flexible coating component 2, the side of the flexible coating component 2 that contacts the inner wall of the mold pole can be oiled. Furthermore, to facilitate the application of the flexible coating component 2... The flexible coating part 2 can be replaced. The flexible coating part 2 and the elastic arc part 1 can be detachably connected. The detachable connection can be made by means of buckles, Velcro, etc. After the elastic arc part 1 enters the rod mold, it adaptively adjusts its overall shape according to the diameter of different positions of the rod mold through the elastic deformation of the elastic arc part 1. Where the diameter of the rod mold is small, the elastic arc part 1 shrinks inward and where the diameter of the rod mold is large, the elastic arc part 1 expands outward, always closely fitting the inner wall of the rod mold, avoiding uneven coating or missed coating due to poor fitting. It is suitable for coating rods of different specifications and models.

[0022] To support the elastic arc-shaped component 1, a crossbeam 3 is also included. Two shifting components 31 are slidably connected on the crossbeam 3. The two shifting components 31 are fixedly connected to both ends of the elastic arc-shaped component 1. When the curvature of the elastic arc-shaped component 1 changes with the inner diameter of the mold, the shifting components 31 are driven to move synchronously, preventing the elastic arc-shaped component 1 from popping out of the mold as the diameter of the mold changes, thus maintaining the stability of the elastic arc-shaped component 1. The crossbeam 3 is also provided with an injection mechanism for injecting release fluid into the mounting cavity 21. The output end of the injection mechanism is connected to the shifting component 31, which can inject release fluid into the elastic arc-shaped component 1 in real time by moving synchronously with the movement of the two ends of the elastic arc-shaped component 1.

[0023] Reference Figure 1 As shown, furthermore, telescopic support members 6 are connected to both ends of the cross frame 3. The telescopic support members 6 can be electric telescopic rods, etc., and the bottom end of the telescopic support members 6 is connected to casters 61. In use, the cross frame 3 is set on the upper end of the rod mold, and the two telescopic support members 6 are located on both sides of the rod mold. The height of the cross frame 3 is adjusted by the telescopic support members 6, so that the elastic arc-shaped member 1 can fit against the inner wall of the rod mold. Then, the casters 61 drive the device to move along the axis of the rod mold to apply oil to the inner wall of the rod mold.

[0024] Reference Figure 1 As shown, the injection mechanism further includes a container 4 mounted on the crossbeam 3. The container 4 is used to hold the release fluid. A hose 41 is connected to the bottom of the container 4. The hose 41 is fixedly connected to the shifting member 31 and its output end extends into the interior of the container cavity 21. A valve 42 is provided on the hose 41. When the shifting member 31 moves synchronously with the change in the curvature of the elastic arc member 1, it will drive the output end of the hose 41 to move synchronously. This ensures that the release fluid is always added into the container cavity 21, avoiding the inaccurate addition of the release fluid into the container cavity 21 due to the change in the curvature of the elastic arc member 1, which would cause the supply of the release fluid into the container cavity 21 to be interrupted, affecting the uniformity of the coating on the rod mold. Furthermore, the flow rate of the release fluid or the opening and closing of the hose 41 can be controlled by the valve 42 according to the actual use.

[0025] To prevent the downward-concave elastic arc-shaped component 1 from bouncing upward within the rod mold as its diameter gradually changes, thus failing to fit against the inner wall of the rod mold, a pressing rod 5 is threaded onto the crossbar 3. The bottom end of the pressing rod 5 is aligned with the valley point of the elastic arc-shaped component 1. After the crossbar 3 is positioned at the upper end of the rod mold, the pressing rod 5 is rotated so that the bottom end of the pressing rod 5 contacts the valley point of the arc-shaped elastic component, thereby limiting the elastic arc-shaped component 1. In order to adapt to the gradual decrease in the diameter of the rod mold, the position of the valley point of the elastic arc-shaped component 1 will also change accordingly. The pressing rod 5 includes a first connecting part 51 and a second connecting part 52. The first connecting part 51 and the second connecting part 52 are connected by a spring 53. When the diameter of the rod mold decreases, the second connecting part 52 compresses the spring 53, so that the length of the pressing rod 5 decreases synchronously, making it adapt to the change in the diameter of the rod mold.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
