Description

Technical Field

[0001] This utility model relates to the field of concrete pole production technology, specifically a multi-directional distributed support and fixing device for concrete poles. Background Technology

[0002] In the fields of power engineering construction and concrete product manufacturing, concrete poles serve as core supporting components for transmission lines. They are characterized by their large individual weight, long and narrow shape, and susceptibility to surface damage from impacts. During the production, demolding, factory transfer, and on-site installation of concrete poles, specialized support and fixing devices are required to ensure the stable placement and movement of the poles, preventing them from tilting or collapsing and causing safety accidents.

[0003] A search revealed a Chinese patent with publication number CN221775876U, which discloses a transfer device for producing concrete poles. The device includes a support frame with at least four casters at the lower end. A rotating shaft is provided on each side of the upper end of the support frame. Multiple clamping assemblies are arranged along the length of the shaft. Each clamping assembly includes a fixed rod fixed to the shaft and a sliding rod that can slide along the length of the fixed rod. A connecting plate is fixed to the end of the sliding rod.

[0004] However, the existing device lacks a flexible lifting and adjustment mechanism and can only be adapted to concrete poles of a specific diameter. For poles of different specifications, different support components need to be replaced, which is cumbersome to operate and has low equipment versatility. Therefore, a new solution is needed to solve this problem. Utility Model Content

[0005] In view of the shortcomings and defects of the existing technology mentioned above, such as cumbersome operation and low equipment versatility, the technology is intended to address these issues.

[0006] The present invention discloses a multi-directional distributed support and fixing device for concrete utility poles, comprising a movable frame, wherein four corners of the lower end of the movable frame are equipped with universal wheels with brakes, and at least two lifting plates are installed on both sides of the movable frame. The lifting plates are slidably mounted on the movable frame, a fixing component is provided between two opposite movable frames, and a driving component is provided between the lifting plates and the movable frame.

[0007] Furthermore, the fixing component includes a mounting plate, and two mounting plates are provided. The two mounting plates are respectively installed on the upper end of the corresponding lifting plate. A pressure plate is provided between the two mounting plates. One end of the pressure plate is rotatably connected to one of the mounting plates through a rotating shaft. A fixing bolt is provided between the other end of the pressure plate and the other mounting plate. One end of the fixing bolt passes through one side of the mounting plate and the pressure plate, and is threadedly connected to the other side of the mounting plate.

[0008] Furthermore, the drive assembly includes a bidirectional threaded rod, which is rotatably mounted on the movable frame via a mounting block. Two sliders are provided on the bidirectional threaded rod, and the sliders are threadedly connected to the bidirectional threaded rod. The sliders are slidably disposed with respect to the movable frame. A connecting plate is provided between the bidirectional threaded rod and the upper part of the lifting plate, and the two ends of the connecting plate are respectively hinged to the sliders and the lifting plate.

[0009] Furthermore, a transmission rod is provided between the two bidirectional threaded rods on both sides. The transmission rod is rotatably mounted on the movable frame. Both ends of the transmission rod and the bidirectional threaded rod are equipped with bevel gears. The bevel gear at the upper end of the transmission rod meshes with the bevel gear at the upper end of the bidirectional threaded rod for transmission. A drive source is provided between the middle of the transmission rod and the movable frame.

[0010] Furthermore, a connecting sleeve is provided between the two bidirectional threaded rods on the same side, and the two ends of the connecting sleeve are respectively fixedly connected to one end of the two adjacent bidirectional threaded rods.

[0011] Furthermore, a controller is installed on the upper part of one end of the mobile frame, and a battery is installed on the lower part of the mobile frame at the same end as the controller. The controller is electrically connected to the drive source and the battery.

[0012] Furthermore, the upper surface of the movable frame is provided with an arc-shaped surface, which is located in the middle of the movable frame, and elastic buffer pads are fixedly attached to the side surfaces of the pressure plate and the arc-shaped surface that are close to each other.

[0013] Furthermore, the pressure plate is arc-shaped, and the mounting plate is connected to the lifting plate by fixing bolts.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model utilizes the cooperation between the bidirectional threaded rod component, the slider component, and the connecting plate component to drive the lifting plate to slide. In conjunction with the transmission rod and the drive source, it achieves synchronous adjustment on both sides, which can flexibly adapt to concrete poles of different diameters without the need to replace the support components. This solves the problem that existing devices can only adapt to poles of specific diameters and are cumbersome to operate, and achieves flexible lifting and clamping adjustment capabilities.

[0015] 2. The fixing component of this utility model adopts an arc-shaped pressure plate that cooperates with the arc-shaped surface of the moving frame to ensure the stability of the pole placement; at the same time, both the pressure plate and the arc-shaped surface are fitted with elastic buffer pads to avoid collision damage to the pole surface during clamping or transportation. In addition, the moving frame is equipped with braked universal wheels, which can facilitate transportation and fix the position to prevent tipping, thus improving the safety of use.

Detailed Implementation

[0018] The following illustrations will reveal several embodiments of the present invention. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these physical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in a simple schematic manner in the illustrations.

[0019] Please see Figure 1 , Figure 3 The present invention relates to a multi-directional distributed support and fixing device for concrete utility poles, comprising a movable frame 1. The movable frame 1 is made of Q355B high-strength low-alloy structural steel, which is treated by shot blasting and electrostatic powder coating to improve its corrosion resistance and adapt to outdoor humid and dusty working environments. The four corners of the lower end of the movable frame 1 are equipped with braked universal wheels 3. The braked universal wheels 3 are heavy-duty polyurethane wheels, and the braking mechanism adopts a dual braking design of wheel-side braking and axial locking.

[0020] See Figure 1 , Figure 4 , Figure 5As shown, at least two lifting plates 4 are installed on both sides of the mobile frame 1. The lifting plates 4 are slidably installed on the mobile frame 1. A fixing component is provided between the two opposing mobile frames 1. The fixing component includes a mounting plate 13. The mounting plate 13 is made of Q235 steel plate. There are two mounting plates 13. The two mounting plates 13 are respectively installed on the upper end of the corresponding lifting plate 4. A pressure plate 14 is provided between the two mounting plates 13.

[0021] See Figure 5 As shown, one end of the pressure plate 14 is rotatably connected to one of the mounting plates 13 via a rotating shaft 15. The rotating shaft 15 is a stainless steel shaft, fitted with a copper bushing bearing. A fixing bolt 16 is provided between the other end of the pressure plate 14 and the other mounting plate 13. One end of the fixing bolt 16 passes through one side of the mounting plate 13 and the pressure plate 14, and is threadedly connected to the other side of the mounting plate 13. The fixing bolt 16 is a high-strength bolt with a hot-dip galvanized surface and a matching flat washer. The pressure plate 14 is designed to be arc-shaped.

[0022] See Figure 5 As shown, the mounting plate 13 and the lifting plate 4 are connected by fixing bolts. The fixing bolts are M12×50mm high-strength bolts. The upper end face of the moving frame 1 is provided with an arc-shaped surface 2, which is located in the middle of the moving frame 1. The pressure plate 14 and the side surface of the arc-shaped surface 2 that are close to each other are fixedly attached with elastic buffer pads. The elastic buffer pads are made of neoprene rubber and have diamond-shaped anti-slip texture on the surface. This not only prevents scratching the concrete surface of the pole when clamping, but also buffers the impact force during transportation and bumping.

[0023] See Figure 5 As shown, a drive assembly is provided between the lifting plate 4 and the movable frame 1. The drive assembly includes a bidirectional threaded rod 5, which is rotatably mounted on the movable frame 1 via a mounting block 6. Two sliders 8 are provided on the bidirectional threaded rod 5, which are threadedly connected to the bidirectional threaded rod 5. The sliders 8 are slidably disposed with respect to the movable frame 1. A connecting plate 7 is provided between the bidirectional threaded rod 5 and the upper part of the lifting plate 4. The two ends of the connecting plate 7 are hinged to the sliders 8 and the lifting plate 4, respectively.

[0024] See Figure 1 , Figure 2 As shown, a transmission rod 10 is provided between the two bidirectional threaded rods 5 on both sides. The transmission rod 10 is rotatably mounted on the movable frame 1. The bidirectional threaded rods 5 and the transmission rod 10 are made of 40Cr alloy steel, which is heat treated and hard chrome plated on the surface to reduce thread wear. Both ends of the transmission rod 10 and the bidirectional threaded rod 5 are equipped with bevel gears 12. The bevel gear 12 at the upper end of the transmission rod 10 meshes with the bevel gear 12 at the upper end of the bidirectional threaded rod 5 for transmission.

[0025] See Figure 1 , Figure 2 , Figure 3As shown, a protective shell is provided on the outer side of the bevel gear 12. The protective shell is fixedly installed on the moving frame 1. A drive source 11 is provided between the middle of the transmission rod 10 and the moving frame 1. The drive source 11 is a DC servo motor equipped with a planetary reducer and an encoder. A connecting sleeve 9 is provided between the two bidirectional threaded rods 5 on the same side. The two ends of the connecting sleeve 9 are fixedly connected to one end of the two adjacent bidirectional threaded rods 5 respectively.

[0026] See Figure 1 , Figure 3 As shown, the connecting sleeve 9 and the bidirectional threaded rod 5 are connected by welding and keyway to ensure transmission synchronization. A controller 17 is installed on the upper part of one end of the moving frame 1, and a storage battery 18 is installed on the lower part of the moving frame 1 at the same end as the controller 17. The controller 17 is electrically connected to the drive source 11 and the storage battery 18. The storage battery 18 is a low-temperature lithium iron phosphate battery with a heat insulation cotton cover.

[0027] The implementation principle is as follows: When in use, push the mobile frame 1, and move the device to the side of the concrete pole through the braked casters 3; step on the brake mechanism of the braked casters 3 to lock the wheel body; The controller 17 is activated to start the drive source 11. The drive source 11 drives the transmission rod 10 to rotate. The two ends of the transmission rod 10 drive the two bidirectional threaded rods 5 on both sides to rotate through the bevel gear 12. This drives the two bidirectional threaded rods 5 on both sides to rotate synchronously on the mounting block 6. The two bidirectional threaded rods 5 on the same side are connected by the connecting sleeve 9 to ensure synchronous rotation. When the bidirectional threaded rods 5 rotate, the slider 8 connected by the thread on its surface slides along the moving frame 1. The slider 8 drives the lifting plate 4 to slide on the moving frame 1 through the connecting plate 7, realizing the synchronous adjustment of the height of the lifting plate 4 until the fixed component reaches the height that is suitable for the current pole diameter. The concrete pole is placed on the arc-shaped surface 2 in the middle of the mobile frame 1. The pressure plate 14 is driven to rotate around the rotating shaft 15, so that the arc-shaped pressure plate 14 is fastened to the surface of the pole. The other end of the pressure plate 14 is passed through the mounting plate 13 and threaded to one side of the mounting plate 13 by the fixing bolt 16, thus completing the clamping and fixing of the pole. If the utility pole needs to be moved, release the brake on the universal caster 3 with brake, push the moving frame 1 to move the utility pole to the target position, or connect the moving frame 1 to the transport vehicle for movement; after reaching the target position, press the brake on the universal caster 3 with brake again to lock the wheel body, so that the device and the utility pole are in a stable state, and then subsequent installation, storage and other operations can be carried out.

[0028] Weekly maintenance includes cleaning the surface of the bidirectional threaded rod 5 and slider 8, applying lithium-based grease, and monthly maintenance including checking the battery voltage and charging it promptly.
