Description

Technical Field

[0001] This utility model relates to the field of cast-in-place pile reinforcement processing, and in particular to a processing device for the inner support ring of the cast-in-place pile reinforcement cage. Background Technology

[0002] The reinforcing cage of a bored pile is an important component in the construction of bored piles. It is made of steel bars. The reinforcing cage primarily increases the strength and stability of the pile, bears part of the pile load, and significantly improves the bearing capacity of the bored pile. In bridge, culvert, or high-rise building construction, the reinforcing cage is a crucial part of the piling process. By lowering the reinforcing cage into the pile hole and then inserting a tremie pipe for concrete pouring, the quality and stability of the bored pile can be ensured.

[0003] During the processing of cast-in-place pile reinforcement cages, several annular inner support rings need to be uniformly welded and fixed within the cage. These inner support rings enhance the load-bearing capacity and bending resistance of the reinforcement cage. Currently, these annular inner support rings are typically processed using a bending machine. During processing, the reinforcing bars are placed inside a guide wheel assembly, and the rotation of the guide wheel assembly gradually bends and expands the reinforcing bars into a circular shape. This processing method requires the operator to hold the ends of the reinforcing bars by hand throughout the process to ensure that the reinforcing bars remain in a balanced state during bending. This method of handling the reinforcing bars one by one is inefficient and requires a high level of operator skill, which can easily lead to inconsistent processing quality due to improper operation.

[0005] The technical solution of this utility model is: a processing device for the inner support ring of a cast-in-place pile reinforcement cage, including a processing platform and a rotating bracket installed on the upper part of the processing platform. The rotating bracket is generally circular, and a rotating shaft is provided at the center of the processing platform. Inside the processing platform is a driver that drives the rotating shaft to rotate. The driver includes a motor and a reducer. The rotating shaft is connected to the output shaft of the reducer through a coupling. The rotating bracket includes a base and several vertical support rods with a circular center evenly distributed on the edge of the base surface. The center of the base is fixedly connected to the rotating shaft. A limiting rod corresponding to the vertical support rod is provided on the edge of the base. The size of the limiting rod is smaller than the size of the vertical support rod, and a clamping gap is formed between the limiting rod and the vertical support rod. The size of the clamping gap matches the size of the reinforcement to be processed. A guide rod is vertically provided at the corner of the processing platform surface. The guide rod is required to have high support strength. The side of the guide rod is located on the tangential extension line of the cylinder composed of several vertical support rods.

[0006] Preferably, a rotating sleeve is installed on the guide rod, and bearings are installed at both ends of the rotating sleeve and between the guide rod.

[0007] Preferably, the base includes a square sleeve and several horizontal support rods that are evenly connected in a circle to the outer side of the square sleeve.

[0020] Example 1, see appendix Figure 1-4 A processing device for the inner support ring of a cast-in-place pile reinforcement cage includes a processing platform 1 and a rotating bracket 2 installed on the upper part of the processing platform. A rotating shaft 11 is located at the center of the processing platform 1. Inside the processing platform 1 is a driver that drives the rotating shaft 11 to rotate. This driver is a motor, and the output shaft of the motor is connected to the rotating shaft 11 via a coupling to drive its rotation. This driver is common prior art and therefore not shown in the accompanying drawings. The rotating bracket 2 includes a base and several vertical support rods 21, which are circular at the center of the base and evenly distributed along the edges of the base surface. The vertical support rods are welded and fixed to the base. To ensure its support strength, the center of the base is fixedly connected to the rotating shaft 11. A limiting rod 22 corresponding to the vertical support rod 21 is provided on the edge of the base. A clamping gap is formed between the limiting rod and the vertical support rod. This clamping gap is used to clamp the end of the steel bar 4 to be processed. A guide rod 13 is vertically provided at the corner of the surface of the processing platform 1. The side of the guide rod 13 is located on the tangential extension line of the cylinder composed of several vertical support rods 21. The steel bar 4 is accurately guided to the outside of the rotating bracket 2 through the guide rod 13, and the rotating bracket 2 provides a limit for the winding processing of the steel bar 4.

[0021] A rotating sleeve 14 is installed on the guide rod 13. Bearings 15 are installed at both ends of the rotating sleeve and between the guide rod 13. The sleeve provides rotational support for the steel bar 4 entering the rotating bracket 2, provides feeding guidance for the steel bar 4, and reduces the friction during the guiding process, ensuring that it is smoothly introduced into the rotating bracket 2.

[0022] A stacking bar 16 is provided on the processing platform 1 outside the guide rod 13. The stacking bar is vertically and fixedly connected to the side of the processing platform 1. After a steel bar 4 is processed, a section of waste steel bar head 41 with a length less than the length of the inner support ring 42 will be left at its rear end. The steel bar head 4 can be leaned against the stacking bar 16 for easy centralized placement and subsequent processing. Several steel bar supports 3 are placed at equal intervals in front of the processing platform 1. The ends of the steel bar supports are provided with extension rods 31. The steel bars 4 to be processed are stacked between the steel bar supports 3. The extension rods 31 are used to place the steel bars 4 to be processed. Columnar handrails 17 are fixedly connected to the edges of both sides of the processing platform 1 by means of hoops.

[0023] The method and principle of using this device are as follows: The steel bar 4 on the steel bar support 3 is placed onto the extension rod 31 of the support. The end of the steel bar 4 is pulled and fed from the extension rod 31 to the outside of the rotating support 2. The end of the steel bar 4 is then inserted into the clamping gap between the limiting rod 22 and the vertical support rod 21. Then, the rotating shaft 11 is driven to rotate, causing the rotating support 2 to rotate as a whole, thus winding the steel bar 4. During this process, the guide rod 13 provides limiting guidance for the entry end of the steel bar 4, ensuring that the steel bar 4 enters the rotating support 2 in a fixed position. After the rotating support 2 rotates once, a section of the steel bar 4 is processed into a circle. At this point, the rotating support 2 is stopped, and the steel bar 4 is cut off, leaving a circular inner support ring 42. This winding processing method requires no human assistance after the steel bar 4 is clamped in, and can automatically complete the process of processing the inner support ring 42 into a circle, resulting in high processing efficiency.

[0024] Example 2, see appendix Figure 1 , 3 This embodiment is basically the same as Embodiment 1, and will not be repeated hereafter. The difference is that the base includes a square sleeve 23 and several horizontal support rods 24 that are evenly connected to the outer side of the square sleeve 23 in a circular shape. The square sleeve 23 is the skeleton of the horizontal support rods 24. The horizontal support rods 24 are welded and fixed to the square sleeve 23 to form the base structure. The vertical support rods 21 are vertically connected to the horizontal support rods 24. This base structure can be processed and manufactured using the waste steel bars 4 at the construction site, which helps to save costs. The square sleeve 23 is fixedly fitted onto the rotating shaft 11. An auxiliary shaft 12 is integrally connected to one side of the rotating shaft 11. The auxiliary shaft 12 is fitted into the gap formed between the square sleeve 23 and the horizontal support rods 24. The auxiliary shaft 12 and the rotating shaft 11 form a claw structure. The middle part of the base is fitted into the claw structure to realize its docking with the processing platform 1. The assembly and disassembly process is convenient and quick.

[0025] A ring-shaped reinforcing rib 25 is fixedly connected between the upper ends of several vertical support rods 21. The ring-shaped reinforcing rib 25 provides reinforcement support between the upper ends of the vertical support rods 21, ensuring the winding load-bearing capacity of the vertical support rods 21.
