Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for the production of reinforcing cages for utility poles, specifically a device for adjusting the angle of the main reinforcing bars in a reinforcing cage for a utility pole. Background Technology

[0002] As a crucial component of infrastructure for power transmission and communication signal transmission, the structural stability of utility poles directly impacts the safe operation of related systems. The reinforcing cage is the core framework of the concrete-cast utility pole, and the main reinforcing bars, as the primary load-bearing components of the cage, have a decisive influence on the pole's load-bearing capacity, wind resistance, and overall structural strength due to their precise installation angle.

[0003] During the fabrication of the steel reinforcement cage for utility poles, multiple main reinforcing bars need to be evenly distributed on the outer circumference of the cage according to the design angle to ensure that the utility pole formed after the subsequent concrete pouring meets the mechanical performance requirements. Currently, the industry mostly uses manual positioning or simple support to fix the main reinforcing bars of the cage by adjusting their angles: construction workers visually estimate the angle based on their experience, use ropes, temporary supports and other tools to temporarily fix the main reinforcing bars, and then carry out binding or welding operations.

[0004] The traditional adjustment method is difficult to guarantee in terms of angle accuracy. The subjective error of manual operation is large, resulting in poor consistency of the angles of multiple main bars, which directly affects the stress balance of the steel cage. It also has poor versatility, requiring different auxiliary tools for steel cages of different diameters, resulting in poor adaptability. Therefore, a new solution is needed to solve this problem. Utility Model Content

[0005] In view of the above-mentioned background technology, the existing technology has shortcomings and defects such as large subjective error and poor versatility due to manual operation of the main reinforcement angle.

[0006] The utility model discloses a device for adjusting the angle of the main reinforcement bars of a utility pole steel cage, including a base and a fixing plate. The fixing plate is fixedly installed on the base. Multiple placement grooves are evenly distributed on the outer ring of the fixing plate. Push blocks are slidably arranged on the fixing plate on one side of each placement groove. Push blocks are provided with push grooves. An adjustment component is provided between the push blocks and the fixing plate. A clamping component is provided between the outer ring of the fixing plate and the base.

[0007] Furthermore, the clamping assembly includes two arc-shaped plates. The lower ends of the two arc-shaped plates are rotatably connected to the base via a pivot. The upper ends of the two arc-shaped plates are provided with fixing bolts that pass through the upper ends of the two arc-shaped plates. The fixing bolts are provided with fixing caps that are threadedly connected to the fixing bolts.

[0008] Furthermore, guide blocks are provided on both sides of the arc-shaped plate, and the inner side of the guide block away from the arc-shaped plate is chamfered. The guide block is slidably disposed with the side of the fixed plate.

[0009] Furthermore, the adjustment component includes a drive disk, which is rotatably mounted on the fixed disk. A drive element is provided between the drive disk and the fixed disk. The drive disk is inclinedly provided with a drive groove. A slide rod is provided inside the drive groove. A slide groove is provided on the fixed disk at the corresponding position of the slide rod. One end of the slide rod passes through the slide groove and is fixedly connected to the push block. A guide element is provided between the push block and the fixed disk.

[0010] Furthermore, the driving component includes a worm gear, which is fixedly mounted on the driving disk. A worm is engaged with one side of the worm gear. A protective shell is provided on the outer side of the worm and the worm gear. The protective shell is fixedly connected to the fixed disk. The worm is rotatably mounted on the protective shell, and one end of the worm passes through the protective shell.

[0011] Furthermore, the guide member includes a guide plate, which is fixedly mounted on the fixed disk and slidably disposed with respect to the push block.

[0012] Furthermore, the inner walls of the placement groove and the push groove are fixedly fitted with anti-slip pads. The anti-slip pad layer is made of wear-resistant rubber material and is integrally molded, with transverse anti-slip textures evenly distributed on its surface.

[0013] Furthermore, four fixing holes are evenly provided along the edge of the base, and fastening bolts are fitted in the fixing holes to detachably fix the base to the construction table.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model achieves initial positioning of the main reinforcement bars through the evenly distributed placement grooves on the outer ring of the fixed plate. With the push groove on the push block and the adjustment component driven by the worm gear, the position of each main reinforcement bar can be adjusted, eliminating the subjective errors caused by traditional manual visual inspection and temporary fixing. Multiple main reinforcement bars can be evenly distributed strictly according to the design angle, ensuring the stress balance of the steel cage, improving the load-bearing capacity, wind resistance and overall structural stability of the subsequently poured power pole, and providing a reliable guarantee for the safe operation of power and communication infrastructure.

[0015] 2. The position of the push block of this utility model can be flexibly shifted and adapted by adjusting the component. Combined with the double arc plate clamping component that can rotate around the axis, there is no need to equip multiple auxiliary tools for steel cages of different sizes, reducing the cost of construction tools. At the same time, the anti-slip pad design enhances the stability of the main reinforcement, and the base fixing hole, together with the fastening bolt, enables the device to be installed stably.

A protective shell 13 is provided on the outer side of the worm 12 and the worm gear 11, and the protective shell 13 is fixedly connected to the fixed disk 2.

[0022] See Figure 2 , Figure 3 , Figure 5 As shown, the worm gear 12 is rotatably mounted on the protective shell 13, and one end of the worm gear 12 passes through the protective shell 13. The protective shell 13 is made of cold-rolled steel plate bent and formed, and is fixed to the fixed plate 2 by bolts. The drive plate 7 is inclinedly provided with a drive groove 10. A slide rod 9 is provided on the inner side of the drive groove 10. The slide rod 9 is made of 40Cr round steel. A slide groove 8 is provided on the fixed plate 2 at the corresponding position of the slide rod 9. The outer ring of the bearing is in contact with the inner wall of the drive groove 10 to reduce sliding friction.

[0023] See Figure 2 , Figure 4 As shown, a guide is provided between the push block 4 and the fixed plate 2. The guide includes a guide plate 5, which has an L-shaped structure. The guide plate 5 is fixedly installed on the fixed plate 2 and slides between the guide plate 5 and the push block 4. A clamping assembly is provided between the outer ring of the fixed plate 2 and the base 1. The clamping assembly includes an arc plate 14, which is made of Q345 steel plate bent and formed, with a wear-resistant rubber pad pasted on the inner side.

[0024] See Figure 2As shown, there are two arc-shaped plates 14. The lower ends of the two arc-shaped plates 14 are rotatably connected to the base 1 via a rotating shaft 15. The upper ends of the two arc-shaped plates 14 are provided with fixing bolts 16, which pass through the upper ends of the two arc-shaped plates 14.

[0025] The implementation principle is as follows: First, fastening bolts are inserted and tightened onto the construction platform through the four fixing holes on the edge of the base 1 to achieve stable installation of the device. Multiple main reinforcing bars of the steel cage to be processed are then placed into the placement groove 3. The anti-slip pads on the inner wall of the placement groove 3 initially restrict the sliding of the main reinforcing bars. Simultaneously, the two arc-shaped plates 14 are rotated, causing them to converge around the axis 15 towards the steel cage, fitting against the outer wall of the steel cage. The guide blocks 17 on both sides of the arc-shaped plates 14 slide along the sides of the fixing plate 2, assisting in precise alignment of the arc-shaped plates 14. After the two arc-shaped plates 14 are fully aligned... After the steel cage is fully fitted, the fixing bolt 16 is passed through the upper end of the arc plate 14 and the fixing cap is tightened to achieve overall clamping and fixing of the steel cage; then the worm gear 12 is rotated, and the drive disk 7 is driven to rotate through the meshing transmission between the worm gear 12 and the worm wheel 11; the drive disk 7 pushes the slide rod 9 to move through the drive groove 10, so that the slide rod 9 slides along the slide groove 8, thereby driving the push block 4 to translate; the push groove 6 on the push block 4 fits against the side of the main bar, and the translation of the push block 4 pushes the main bar, adjusting each main bar to the design position one by one, and cooperating with the arc plate 14 to achieve clamping.

[0026] After each use, concrete residue and dust on the surface of the device must be cleaned. The anti-slip pads should be replaced in time if they are worn. The gear oil of the worm gear 12 and worm wheel 11 mechanism should be changed every 100 uses. The bearing wear should be checked. If there is abnormal noise or increased rotation resistance, the bearings should be replaced. For long-term storage, the surface of the device should be sprayed with anti-rust oil and placed in a dry and ventilated environment to avoid moisture and corrosion.
