Description

Technical Field

[0001] This application relates to the field of power transmission pole manufacturing technology, and in particular to a device for unloading the reinforcing bar tray at the end of a power transmission pole. Background Technology

[0002] The primary function of power transmission poles is to support and secure power transmission lines, ensuring stable and safe power transmission. Based on the voltage level they carry, power transmission poles can be divided into low-voltage transmission poles and high-voltage transmission poles (or distribution line poles and transmission line poles). Low-voltage transmission poles are generally used for power supply in urban and rural areas, such as residential roads, alleyways, and squares, while high-voltage transmission poles are used in areas with larger power grids, such as urban or rural high-voltage power grids, factories, and large enterprises.

[0003] High-voltage transmission poles typically have a high support height and are generally constructed using overlapping angle steel. Low-voltage transmission poles, on the other hand, are commonly used in residential or industrial areas and are currently mostly made of concrete. However, to reduce the weight of low-voltage transmission poles and save materials, hollow transmission poles are now commonly used. Hollow transmission poles are typically described in the instructions attached to the manual. Figure 1-2 The hollow transmission pole is formed by casting within the space created between the inner and outer molds. To enhance the strength of the hollow transmission pole, reinforcing ribs are typically embedded in the side walls. Due to the long length of the transmission pole, to ensure the straightness of the reinforcing ribs during casting, such as… Figure 2 As shown, reinforcing ribs are installed at both ends of the transmission pole. After the reinforcing ribs are passed through the small holes in the rib-passing plates, the ends of the reinforcing ribs are truncated to prevent them from detaching from the rib-passing plates and to straighten them. After the transmission pole is cast and formed, the rib-passing plates need to be removed, such as... Figure 3 As shown, after stretching the reinforcing rib plate outward to a certain length (the reinforcing rib can be deformed and elongated), the reinforcing rib plate is separated from the end of the transmission pole, leaving a gap. The reinforcing rib is then sawn in this gap. Figure 3 (As shown by the dashed line), thus achieving unloading ( Figure 4 (As shown in the image) operation.

[0004] Currently, due to the large number of reinforcing ribs arranged circumferentially inside the transmission pole, there is considerable operational difficulty when pulling the reinforcing rib plate. In other words, it is not possible to pull out a large operating gap between the reinforcing rib plate and the end of the transmission pole. When sawing the reinforcing ribs, the gap is too small, which can easily cause sawing damage to the end of the transmission pole and the reinforcing rib plate. In the case of sawing damage to the end of the transmission pole, it can also cause the concrete body to crack (in pieces), resulting in an incomplete end of the transmission pole. Summary of the Invention

[0005] To address the aforementioned problems, this application aims to provide a device for unloading the reinforcing rib tray at the end of a power transmission pole. This device can safely and quickly unload the reinforcing rib tray using mechanical force, while simultaneously balancing the tension on each reinforcing rib to avoid the impact on the quality of the power transmission pole end under skewed pulling conditions.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows: a device for unloading a reinforcing rib plate at the end of a power transmission pole, wherein reinforcing ribs are evenly distributed along the circumference of the side wall of the power transmission pole, and a reinforcing rib plate is provided at the end of the power transmission pole, characterized in that: the unloading device includes a connector detachably connected to the reinforcing rib plate, a drive cylinder is connected to the tail end of the connector, and a frame for placing and adjusting the power transmission pole is provided on the other side of the connector.

[0007] Preferably, the frame is provided with a front roller group and a rear roller group along the length of the power transmission pole and located on the front and rear sides of the power transmission pole to support the power transmission pole.

[0008] Preferably, the top surface of the front roller group is higher than that of the rear roller group, and the axis of the transmission pole is horizontal when the front roller group and the rear roller group support the transmission pole.

[0009] Preferably, both the front roller assembly and the rear roller assembly are provided with support plates at their bottoms, with adjustment columns at the bottom of the support plates, and an arc-shaped groove with an inner width greater than that of the adjustment column is formed on the surface of the frame.

[0010] The beneficial effects of this application are: the unloading device can safely and quickly pull the reinforcing rib disc away from the transmission pole using mechanical force, and then perform the sawing operation of the reinforcing rib at a larger sawing gap, thus completing the unloading operation at the end of the transmission pole. During the elongation of the reinforcing rib, the transmission pole body can adjust its position on the frame to ensure that the tension on each reinforcing rib is basically consistent, thereby avoiding the impact on the quality of the transmission pole end under skewed pulling conditions.

[0025] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions of this application will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] See attached document Figures 1-13 The present invention discloses a device for removing the reinforcing rib plate at the end of a power transmission pole. The power transmission pole 1 has reinforcing ribs 2 evenly distributed circumferentially along its side wall, and a reinforcing rib plate 3 with the reinforcing ribs 2 inserted at its end. To facilitate the removal of the reinforcing rib plate 3 after the power transmission pole is formed, this application provides a removal device, such as… Figure 5-8As shown, it includes a connector 4 detachably connected to the reinforcing rib plate 3. A drive cylinder 5 is connected to the tail end of the connector 4, and a frame 6 for placing and adjusting the power transmission pole 1 is provided on the other side of the connector 4. During operation, the power transmission pole, after the inner and outer molds are disassembled, is hoisted and placed on the frame 6. The connector 4 is connected to the end of the reinforcing rib plate 3 (preferably by a threaded connection). The power transmission pole 1 remains stable based on its own weight. The drive cylinder 5 pulls the reinforcing rib plate 3 to stretch the reinforcing ribs to a certain length, so that a gap is formed between the reinforcing rib plate and the end of the power transmission pole, which facilitates sawing operations. Figure 7 As shown in the figure, the reinforcing rib is then cut in the gap to separate the reinforcing plate 3 from the power transmission pole and the reinforcing rib, thus realizing the unloading operation.

[0027] Because the reinforcing ribs are evenly distributed circumferentially in the side wall of the transmission pole 1, they need to be stretched synchronously. If there is a vertical deviation between the connector 4 and the axis of the transmission pole, there will be a problem of excessive tensile force on some reinforcing ribs during the stretching process through the connector 4, resulting in premature stretching. This means that multiple reinforcing ribs will stretch asynchronously, leading to uneven tensile force and deviation. Under the action of the deviated tensile force, the force transmitted to the end of the transmission pole through the reinforcing ribs will be inconsistent, which will cause cracks and fragmentation in the concrete structure. Figure 9-10 As shown, the frame provided in this application can be adjusted, that is, during the process of pulling the reinforcing plate, the main body of the transmission pole can adjust its position state by itself to balance the tension on each reinforcing rib to be basically the same, thereby avoiding the impact on the quality of the end of the transmission pole under the skewed pulling state.

[0028] Specifically, such as Figure 6 As shown, the frame 6 is provided with a front roller assembly 71 and a rear roller assembly 72 along the length of the transmission pole 1 and located on the front and rear sides of the transmission pole 1 to support the transmission pole 1. Both the front roller assembly 71 and the rear roller assembly 72 include rollers symmetrically arranged on the left and right sides to support the transmission pole 1 from both sides. Figure 6 As shown. The front roller assembly 71 and the rear roller assembly 72 are used to support the power transmission pole after it has been hoisted and placed, and to allow the main body of the power transmission pole to rotate and be threadedly connected to the connector 4. Then, the drive cylinder 5 can apply a pulling force to pull the threading plate 3 a certain length for sawing operation.

[0029] To improve the linear elongation of the reinforcing ribs during the pulling process of the reinforcing rib plate 3, such as Figure 6As shown, the top surface of the front roller group 71 is higher than that of the rear roller group 72, and the axis of the transmission pole 1 is horizontal when the front roller group 71 and the rear roller group 72 support the transmission pole 1. Since the transmission pole is usually a tapered structure, the front roller group 71 and the rear roller group 72, which are of different heights, support the transmission pole, ensuring that the axis of the transmission pole is horizontal. This ensures that each reinforcing rib is stretched evenly during subsequent pulling. At the same time, due to the tapered structure of the transmission pole and the fact that the top surface of the front roller group 71 is higher than that of the rear roller group 72, if the transmission pole moves axially during the pulling process, the outer diameter of the transmission pole gradually increases towards the rear, while the front roller group 71 has a higher supporting top surface. Therefore, if the transmission pole moves along with the front roller group 71, the axial friction force and upward supporting force on the transmission pole will increase, thus overcoming the pulling of the transmission pole and ensuring the stability of the transmission pole during the pulling of the reinforcing ribs.

[0030] To further address the issue of uneven elongation of the reinforcing ribs during the pulling process, which is caused by the axial deviation between the reinforcing rib plate 3 and the transmission pole and affects the quality of the transmission pole end, such as... Figure 11-13 As shown, both the front roller assembly 71 and the rear roller assembly 72 are equipped with support plates 8 at their bottoms. An adjusting column 81 is located at the bottom of the support plate 8, and an arc-shaped groove 6a with an inner width greater than the adjusting column 81 is formed on the surface of the frame 6. During the pulling process via the connector 4, when the tension on the multiple reinforcing ribs is uneven, the adjusting column 81 moves within the arc-shaped groove 6a to adaptively adjust the pulling state of the transmission pole, thereby improving the consistency of the tension on the multiple reinforcing ribs and eliminating the influence of the misalignment between the reinforcing plate 3 and the transmission pole.

[0031] The principle of this application is as follows: During the unloading operation of the transmission pole, the transmission pole after the inner and outer molds are disassembled is hoisted and placed on the frame 6. It is connected to the end of the reinforcing plate 3 through the connector 4. The transmission pole 1 remains stable based on its own weight. The driving cylinder 5 is used to drive the reinforcing plate 3 to stretch the reinforcing ribs to a certain length. During the stretching process of the reinforcing ribs, the tension can be balanced to a certain extent through the tension action. That is, the transmission pole adapts to the frame through the front roller group 71 and the rear roller group 72, avoiding the impact of inconsistent stretching length of the reinforcing ribs on the end support of the transmission pole. After the reinforcing plate and the end of the transmission pole form a gap that facilitates the sawing operation, the reinforcing ribs are sawn, realizing the separation of the reinforcing plate 3 from the transmission pole and the reinforcing ribs, that is, realizing the unloading operation.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this application. Various changes and modifications may be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
