Description

Technical Field

[0001] This utility model relates to the field of steel cage processing technology, and in particular to a precise processing and positioning device for double main reinforcement steel cages. Background Technology

[0002] The steel reinforcement cage is a major component of pile foundations, and its processing accuracy and quality are of paramount importance.

[0003] For example, Chinese utility model patent CN207770703U discloses a "processing jig for multi-diameter cylindrical steel cages". This device includes a mounting base, with a positioning mechanism on the side of the mounting base away from the ground. The positioning mechanism includes an L-shaped connecting frame, one end of which is fixedly connected to the mounting base, and the other end of which is rotatably connected to a turntable. The axis of the turntable is horizontal. Several sliders are distributed circumferentially on the side of the turntable away from the L-shaped connecting frame. The sliders are slidably connected to the turntable. A positioning tube is fixedly connected to the side of the slider away from the L-shaped connecting frame. A threaded rod is connected to the side of the slider near the axis of the turntable. A sleeve is threadedly connected to the threaded rod. A spur gear is connected to the end of the sleeve away from the threaded rod. An end face gear is rotatably connected to the turntable. The spur gear meshes with the end face gear. A protective shell is connected to the side of the turntable near the end face gear. The sleeve passes through the protective shell and is rotatably connected to it. This device can adjust the spacing of the main reinforcement bars of the steel cage with high precision.

[0004] However, since the above-mentioned device can only position steel cages of fixed specifications, different pile foundations have different requirements for steel cages in actual applications. This results in the need for corresponding positioning devices when positioning and manufacturing different steel cages, leading to high costs and a limited range of applications. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a precision processing and positioning device for double main reinforcement cages. This device solves the problem that existing technologies require corresponding positioning devices when positioning and manufacturing different reinforcement cages, resulting in high costs and limited application range.

[0006] According to an embodiment of this utility model, a precision machining and positioning device for double-reinforced steel cages includes a ring frame; multiple sets of positioning components, each set including multiple sets of single-reinforced positioning elements and multiple sets of double-reinforced positioning elements, which are spaced apart on the ring frame. Each single-reinforced positioning element and each double-reinforced positioning element includes an adjusting arm adjustablely mounted on the ring frame via a connector and a mounting cylinder fixedly mounted at one end of the adjusting arm. The mounting cylinder is used to mount the reinforcing steel. Multiple sets of limiting devices correspond to the multiple sets of positioning components. Each single-reinforced positioning element is provided with one limiting device, and each double-reinforced positioning element is provided with two limiting devices. The limiting devices are used to fix the reinforcing steel inside the corresponding mounting cylinder.

[0007] Compared with the prior art, this utility model has the following beneficial effects: By adding or removing the required positioning components on the ring frame to correspond to the number of longitudinal bars in the steel cage, and then adjusting the positioning components to ensure even distribution on the ring frame, and tightening the connecting parts, at least two sets of ring frames with the same specifications are adjusted. Then, multiple sets of longitudinal bars are sequentially inserted into the corresponding installation cylinders, with the two ring frames located at both ends of the longitudinal bars. The longitudinal bars in the installation cylinders are then fixed by the limiting device, and finally, the steel cage can be fabricated. This solves the problems of uneven distribution of longitudinal bars and non-compliant bar spacing in the steel cage. At the same time, by adding or removing positioning components on the ring frame to adapt to the requirements of steel cages of different specifications, a single-bar positioning component can hold one longitudinal bar, and a double-bar positioning component can hold two longitudinal bars. By adding or removing single-bar or double-bar positioning components, flexibility is improved, and steel cages of different specifications can be fabricated.

The adjusting arm has a stroke groove, and both ends of the U-shaped seat are located in the stroke groove. One end of the U-shaped seat is provided with a stud, and a nut is threaded onto the stud. The nut abuts against the corresponding adjusting arm.

[0009] Preferably, each limiting device includes a screw and a limiting seat rotatably disposed at one end of the screw, the screw being threadedly connected to the corresponding mounting cylinder, wherein the limiting seat is located inside the mounting cylinder.

[0010] Preferably, a rubber pad is provided at the end of the limiting seat away from the screw.

[0017] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0018] like Figures 1 to 3 As shown in the figure, this utility model embodiment proposes a precision processing and positioning device for double main reinforcement cages, which includes a ring frame 1; multiple sets of positioning components 2, each set of positioning components 2 including multiple sets of single-reinforcement positioning elements 5 and multiple sets of double-reinforcement positioning elements 6, which are spaced apart on the ring frame 1. Each single-reinforcement positioning element 5 and each double-reinforcement positioning element 6 includes an adjusting arm 3 that is adjustablely mounted on the ring frame 1 via a connector and an installation cylinder 4 fixedly mounted at one end of the adjusting arm 3. The installation cylinder 4 is used to install the reinforcing steel; and multiple sets of limiting devices, corresponding to the multiple sets of positioning components 2. Each single-reinforcement positioning element 5 is provided with one limiting device, and each double-reinforcement positioning element 6 is provided with two limiting devices. The limiting devices are used to fix the reinforcing steel inside the corresponding installation cylinder 4.

[0019] The detailed working process of this embodiment is as follows: By adding or subtracting the required positioning components 2 on the ring frame 1, it is made to correspond to the number of longitudinal bars in the steel cage. Then, the positioning components 2 are adjusted to make them evenly distributed on the ring frame 1. After tightening the connecting parts, at least two sets of ring frames 1 with the same specifications are adjusted. Then, multiple sets of longitudinal bars are sequentially inserted into the corresponding installation cylinders 4. The two ring frame positions 1 are located at both ends of the longitudinal bars. The longitudinal bars in the installation cylinders 4 are fixed by the limiting device. Finally, the steel cage can be made, which solves the problems of uneven distribution of longitudinal bars and unqualified bar spacing in the steel cage. At the same time, by adding or subtracting positioning components 2 on the ring frame 1, it can be adapted to the requirements of steel cages of different specifications. A single bar positioning component 5 can hold one longitudinal bar, and a double bar positioning component 6 can hold two longitudinal bars. By adding or subtracting single bar positioning components 5 or double bar positioning components 6, its flexibility is improved, and steel cages of different specifications can be made.

[0020] Both the single-reinforced positioning component 5 and the double-reinforced positioning component 6 are adjustablely mounted on the ring frame 1 via connectors. The positioning components 2 on the ring frame 1 can be determined according to the specifications of the reinforcing cage. Multiple sets of single-reinforced positioning components 5 or multiple sets of double-reinforced positioning components 6 can be evenly distributed on the ring frame 1 as needed, or multiple sets of single-reinforced positioning components 5 and multiple sets of double-reinforced positioning components 6 can be arranged alternately to improve its flexibility of use.

[0021] like Figure 3 As shown, each connector includes a U-shaped seat 303, which is sleeved on the ring frame 1. The adjusting arm 3 has a stroke groove 301. Both ends of the U-shaped seat 303 are located in the stroke groove 301 and can be positioned at one end. A stud 304 is provided at any end of the U-shaped seat 303. A nut 305 is threaded onto the stud 304 and abuts against the corresponding adjusting arm 3.

[0022] The detailed working process of this embodiment is as follows: The U-shaped seat 303 is used to connect the ring frame 1 and the adjusting arm 3. By controlling the U-shaped seat 303, the adjusting arm 3 can move radially and circumferentially on the ring frame 1. When the adjusting arm 3 moves radially, the diameter of the reinforcing cage can be adjusted. When it is close to the axis of the ring frame 1, the diameter of the reinforcing cage decreases, and vice versa. At the same time, the orientation of the positioning component 2 can be changed so that the mounting cylinder 4 is located inside or outside the ring of the ring frame 1, further changing the diameter of the reinforcing cage. When moving circumferentially, the spacing and number of longitudinal bars can be adjusted. Within a certain range, the more positioning components 2 are on the ring frame 1, the smaller the spacing of the longitudinal bars and the denser the longitudinal bars. Conversely, the spacing is larger and sparser. Whether moving radially or circumferentially, it is only necessary to tighten the nut 305. After adjusting to a suitable position, tighten the nut 305 so that it abuts against the adjusting arm 3. At the same time, the adjusting arm 3 abuts against the ring frame 1 to complete the fixation.

[0023] like Figure 3 As shown, each limiting device includes a screw 403 and a limiting seat 402 rotatably disposed at one end of the screw 403. The screw 403 is threadedly connected to the corresponding mounting cylinder 4, wherein the limiting seat 402 is located inside the mounting cylinder 4.

[0024] The detailed working process of this embodiment is as follows: With the screw 403 and the limiting seat 402 set, the steel bars in the mounting cylinder 4 can be fixed to avoid the steel bars moving during the manufacturing process and affecting the quality of the steel cage. When fixing, the screw 403 is directly turned to drive the limiting seat 402 to move in the direction of the axis of the mounting cylinder 4 until the limiting seat 402 clamps the steel bars.

[0025] like Figure 3 As shown, a rubber pad 401 is provided at the end of the limiting seat 402 away from the screw 403.

[0026] The detailed working process of this embodiment is as follows: with the rubber pad 401 in place, the friction between the limiting seat 402 and the reinforcing bar is increased, thereby improving stability.

[0027] like Figure 3 As shown, each adjusting arm 3 is provided with a second scale 302.

[0028] The detailed working process of this embodiment is as follows: The function of the second scale 302 on each adjusting arm 3 is to use the second scale 302 on the adjusting arm 3 as a reference so that multiple sets of adjusting arms 3 on the ring frame 1 can be on the same scale.

[0029] like Figure 2 As shown, the ring frame 1 is provided with a first scale 101.

[0030] The detailed working process of this embodiment is as follows: The function of the first scale 101 on the ring frame 1 is to adjust the multiple sets of adjusting arms 3 on the ring frame 1 through the scale so that the spacing between adjacent positioning components 2 is consistent.

[0031] The implementation principle of this application embodiment is as follows: First, the number of positioning components 2 is increased or decreased according to the specifications of the steel cage to be made. After determining the number, the radial and circumferential adjustments are made to the multiple sets of positioning components 2. After adjusting to the appropriate position, the nuts 305 are tightened. Finally, the steel bars are passed through the installation cylinder 4 and the screws 403 are tightened to make the steel cage.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
