Description

Technical Field

[0001] The utility model belongs to the technical field of cast-in-place piles, in particular to a device for manufacturing a cast-in-place pile reinforcement cage reinforcement protection layer bracket. Background Art

[0002] In the process of making cast-in-place pile reinforcement cage, in order to meet the requirements of reinforcement cage reinforcement protection layer, it is necessary to make reinforcement protection layer bracket, such as Figure 1 As shown, the main function of these brackets is to ensure that the steel cage maintains the correct position during the concrete pouring process and will not be displaced. By maintaining a sufficient thickness of the protective layer, the steel bars are prevented from directly contacting the external environment, thereby slowing down the corrosion rate of the steel bars and improving the durability of the structure.

[0003] Brackets are typically arranged in groups at regular intervals (e.g., 2-4 meters) along the length of the rebar cage. Each group contains several (e.g., 4-6) curved rebar brackets, evenly spaced along the outer circumference of the cage. The shape and size of the brackets are customized based on the cage diameter and design requirements. Traditionally, the cage rebar cover brackets are manually fabricated by workers using a rebar bending machine. This is inefficient and subject to significant human error. There is also the risk of accidental injury during the rebar bending process.

[0004] To this end, we provide a device for manufacturing a cast-in-place pile reinforcement cage reinforcement protective layer bracket to solve the above problems. Summary of the Invention

[0027] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0028] Example 1

[0029] In order to solve the problem that the existing steel cage steel bar protective layer bracket is generally made by workers through the steel bar bending machine, the efficiency is relatively low, the human error is large, and there is also the risk of accidental injury during the steel bar bending process, please refer to Figure 2-Figure 3 The present invention provides a device for manufacturing a cast-in-place pile reinforcement cage reinforcement cover support, comprising a base plate 1 and a movable plate 2 slidably mounted on top of the base plate 1. The movable plate 2 is provided with a plurality of equally spaced stepped holes 201 for placing reinforcement bars. A gantry 101 is fixedly mounted at the end of the base plate 1. A hydraulic cylinder 102 is mounted on the top of the gantry 101. An upper die 103 matching the stepped holes 201 is mounted on the movable end of the hydraulic cylinder 102. The hydraulic cylinder 102 drives the upper die 103 to extrude the reinforcement bars in the stepped holes 201 to produce a trapezoidal reinforcement cage reinforcement cover support. The provision of multiple stepped holes 201 enables the device to produce multiple supports at a time, greatly improving production efficiency.

[0030] In order to facilitate accurate control of the stepped hole 201 so that it can be moved just below the upper die 103, as shown in FIG. Figure 4-Figure 5 As shown, a push handle 203 is provided on the end face of the movable plate 2 for pushing the movable plate 2 to move toward the gantry 101, and a clamping piece 202 is hinged in the hole at the end of the movable plate 2 away from the gantry 101. The cross-sectional shape of the clamping piece 202 is set to be L-shaped, and the short side of the L-shape is located above the movable plate 2 to facilitate manual manipulation. The clamping piece 202 is rotated in the hole of the movable plate 2 through a rotating shaft, and a torsion spring 203a is sleeved on the rotating shaft; a pull groove 204 is provided on the top of the movable plate 2 on the side of the clamping piece 202 for pulling the movable plate 2 to move away from the gantry 101; a plurality of equally spaced clamping grooves 104 are provided on the top of the base plate 1 for cooperating with the clamping piece 202 to limit the movement of the movable plate 2.

[0031] When the lever 202 is in the horizontal position, the lower end of the clamping member 202 is pressed by the bottom plate 1 and is in the horizontal position, and the torsion spring 203a is tightened. As the lever 202 continues to move, when the clamping member 202 moves to the next clamping slot 104, the clamping member 202 is reset to the vertical position under the restoring force of the torsion spring 203a and is locked in the clamping slot 104, thereby preventing the lever 2 from moving further.

[0032] Example 2

[0033] On the basis of the first embodiment, in order to further improve the production efficiency, the brackets that have been manufactured in the stepped hole 201 can be automatically blanked, such as Figure 6-Figure 7 As shown, movable blocks 205 are slidably mounted on the lower inner walls at both ends of stepped hole 201. A groove for retracting movable blocks 205 is provided on movable plate 2, located to the sides of movable blocks 205. A first spring 206 is disposed between movable blocks 205 and the inner wall of the groove. The system also includes two sets of blanking assemblies 3, located at the ends of base plate 1, for pushing movable blocks 205 into the grooves to the sides thereof. When stepped hole 201 moves to blanking assemblies 3, blanking assemblies 3 push movable blocks 205 into the grooves to the sides thereof. At this point, the already fabricated brackets in stepped hole 201, without the support of movable blocks 205, fall into the material receiving box below. This allows for automatic blanking during the movement of movable plate 2, further improving production efficiency.

[0034] like Figure 8 As shown, the blanking component 3 includes a fixed seat 301 fixed on the base plate 1 and a movable rod 302 that is movable through the fixed seat 301. A wedge-shaped stop block 303 is fixed to the top of the movable rod 302. The movable block 205 is provided with an inclined surface 205a that cooperates with the wedge-shaped stop block 303. A second spring 304 is sleeved on the movable rod 302 between the wedge-shaped stop block 303 and the fixed seat 301. When the movable plate 2 moves, the movable block 205 applies a thrust to the wedge-shaped block 303. At this time, the wedge-shaped block 303 drives the movable rod 302 to move down, and the second spring 304 is compressed. At the same time, the wedge-shaped block 303 also applies a counter-thrust to the movable block 205, so that the movable block 205 moves into the groove on its side, and the first spring 206 is compressed. As the movable plate 2 continues to move, the wedge-shaped block 303 gradually moves to the bottom of the movable block 205. At this time, the movable block 205 is reset due to the loss of the pressing effect of the wedge-shaped block 303, and the wedge-shaped block 303 is compressed to the lowest point. As the movable plate 2 continues to move, before the next stepped hole 201 arrives, the upper part of the wedge-shaped block 303 loses its restriction and is reset under the action of the second spring 304. In this way, the brackets in multiple stepped holes 201 can be automatically unloaded.

[0035] The above-described embodiment merely represents one embodiment of the present invention. While the description is relatively specific and detailed, it should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements are all within the scope of protection of the present invention.
