Description

Technical Field

[0001] This utility model belongs to the field of PCCP pipe processing, specifically relating to a pneumatic clamp for steel wire used in a PCCP wire winding machine. Background Technology

[0002] Prestressed concrete cylinder pipe refers to a water pipe made by winding circumferential prestressed steel wires around a high-strength concrete core with a steel cylinder, and then spraying a dense cement mortar protective layer on it. In the processing of PCCP pipes, multiple processes are required. The core winding process is an important quality control point in PCCP manufacturing. The concrete core is hoisted to the workbench of the winding machine, and the prestressed steel wires are spirally wound on the core with the designed tensile stress and spacing.

[0003] Chinese utility model patent CN212639545U discloses a pneumatic clamp for prestressed steel wire in a PCCP differential speed winding machine, used in the PCCP pipe core winding process. It is particularly suitable for overlapping and binding a second coil of steel wire with the first coil of steel wire during the core winding process when the first coil of prestressed steel wire is exhausted without stopping the prestressing. The clamp consists of a telescopic cylinder, an active scissor arm, a driven scissor arm, a clamp with connecting ears, a stop block, a slide rail, a base support, a controller, a connecting pipe, and a connecting shaft.

[0004] The above design, through the cooperation of multiple components, can achieve semi-automatic control of existing pneumatic clamps and assist in the stable operation of the wire winding machine. However, there are certain problems in actual use. Specifically, when the equipment is in use, it mainly relies on the clamps and baffles to hold the steel wire and achieve the positioning of the steel wire. Although this method can stably limit the steel wire, the inner walls of both the clamps and baffles are flat. When clamping the steel wire, the steel wire itself is subjected to excessive extrusion force, which can easily cause the steel wire to deform and affect the practical effect of the subsequent pipeline.

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] To address the problems mentioned in the background section, the present invention adopts the following technical solution.

[0007] A pneumatic clamp for a PCCP wire winding machine includes a base, a fixing plate, and an extrusion component. The fixing plate is installed on one side of the base surface, and the extrusion component is installed on the other side of the base surface. An extrusion mechanism is installed on the upper surface of the base. The extrusion mechanism includes a mounting plate and a cylinder. The mounting plate is fixedly installed on the upper surface of the base, and the cylinder is installed on the side of the mounting plate. The output end of the cylinder passes through the mounting plate and is connected to the side of the extrusion component.

[0008] As a preferred embodiment of the present invention, the extrusion mechanism further includes an extrusion plate, which is installed on the side of the extruded part.

[0009] As a preferred technical solution of this utility model, the steel wire pneumatic clamp also includes a limiting mechanism, which includes an auxiliary frame, a calibration cylinder, a mating plate and a support base. The support base is fixedly installed on the side of the fixed plate, the auxiliary frames are symmetrically installed on the side of the support base, the calibration cylinder is installed between the auxiliary frames, and the mating plate is installed on the surface of the support base.

[0010] As a preferred technical solution of this utility model, the auxiliary frame further includes a side support, a sliding groove and a sliding block. The side support is fixedly installed on the side of the support base, and a sliding groove is opened inside the side support. The sliding block is slidably installed in the sliding groove and is rotatably connected to the calibration cylinder.

[0011] As a preferred embodiment of this utility model, the auxiliary frame further includes a spring assembly, which is disposed in a sliding groove. When the sliding block slides to the side of the support seat, the spring assembly is in a stored state.

[0012] As a preferred technical solution of this utility model, the calibration cylinder is composed of a rotating cylinder and a locking block.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In this invention, by setting up an extrusion component, a limiting mechanism, and an extrusion mechanism, the distance between the fixed plate and the extrusion component can be adjusted quickly and stably to clamp and limit the steel wire. The use of the extrusion plate and the calibration cylinder can further enhance the stability of the steel wire position locking, facilitate the subsequent connection of the steel wire, and limit the minimum distance between the fixed plate and the extrusion plate to prevent the steel wire from being deformed due to excessively small distance between the fixed plate and the extrusion plate. This ensures the overall stability of the equipment and improves the working quality of the equipment itself. Attached Figure Description

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0026] Depend on Figure 1As shown, it is a structural schematic diagram of the steel wire pneumatic clamp in this embodiment, including a base 1, a fixing plate 2 and an extrusion member 3. The fixing plate 2 is installed on one side of the surface of the base 1, the extrusion member 3 is installed on the other side of the surface of the base 1, and the extrusion mechanism 4 is installed on the upper surface of the base 1.

[0027] In use, the entire device is installed at the output end of the wire winding machine. When the wire in the wire winding machine is insufficient, the extrusion mechanism 4 is used to slide the extrusion piece 3 to one side of the fixed plate 2, clamping and fixing the wire between the fixed plate 2 and the extrusion piece 3. While ensuring the stress of the wire itself, it assists the staff in connecting and joining the wires, extending the length of the wires, and assisting the wire winding machine in processing PCCP pipes.

[0028] From the appendix Figure 2 As shown, it is a structural schematic diagram of the extrusion mechanism 4 in this embodiment. The extrusion mechanism 4 includes a mounting plate 41 and a cylinder 42. The mounting plate 41 is fixedly mounted on the upper surface of the base 1, and the cylinder 42 is mounted on the side of the mounting plate 41. The output end of the cylinder 42 passes through the mounting plate 41 and is connected to the side of the extruded part 3.

[0029] During use, the output end of the cylinder 42 pushes the extruder 3 to move closer to the fixed plate 2. When the distance between the fixed plate 2 and the extruder 3 reaches the preset distance, the fixed plate 2 and the extruder 3 extrude and position the steel wire on both sides. Under the premise of ensuring the stress of the steel wire itself, the position of the steel wire is fixed. The structure of the fixed plate 2 and the extruder 3 is used to assist in the stable clamping of the steel wire.

[0030] From the appendix Figure 2 As shown, it is a structural schematic diagram of the extrusion mechanism 4 in this embodiment. The extrusion mechanism 4 also includes an extrusion plate 43, which is installed on the side of the extrusion piece 3. During use, the extrusion plate 43 moves synchronously with the extrusion piece 3 and, in conjunction with subsequent components, further locks the position of the steel wire.

[0031] From the appendix Figure 3 As shown, it is a structural schematic diagram of the limiting mechanism 5 in this embodiment. The steel wire pneumatic clamp also includes the limiting mechanism 5. The limiting mechanism 5 includes an auxiliary frame 51, a calibration cylinder 52, a mating plate 53, and a support base 54. The support base 54 is fixedly installed on the side of the fixed plate 2. The auxiliary frames 51 are symmetrically installed on the side of the support base 54. The calibration cylinder 52 is installed between the auxiliary frames 51. The mating plate 53 is installed on the surface of the support base 54.

[0032] During use, when the extrusion plate 43 moves synchronously with the extrusion piece 3 to the target position, the extrusion plate 43 extrudes the position of the calibration cylinder 52, causing the calibration cylinder 52 to move closer to the mating plate 53. At this time, the calibration cylinder 52 and the mating plate 53 cooperate to clamp and limit the steel wire. The structure of the calibration cylinder 52 itself prevents the steel wire from sliding or misaligning. The installation of the two sets of auxiliary frames 51 not only assists in the movement of the calibration cylinder 52, but also limits the movement range of the steel wire, ensuring the stability of the subsequent operation of the wire winding machine.

[0033] From the appendix Figure 4 As shown, it is a structural schematic diagram of the auxiliary frame 51 in this embodiment. The auxiliary frame 51 also includes a side support 511, a sliding groove 512 and a sliding block 513. The side support 511 is fixedly installed on the side of the support base 54. The sliding groove 512 is opened inside the side support 511. The sliding block 513 is slidably installed in the sliding groove 512. The sliding block 513 is rotatably connected to the calibration cylinder 52.

[0034] When the calibration cylinder 52 is compressed during use, the sliding block 513 slides inside the sliding groove 512 to adjust the position of the calibration cylinder 52. At this time, the calibration cylinder 52 and the mating plate 53 are close together, further limiting and clamping the steel wire between the calibration cylinder 52 and the mating plate 53.

[0035] From the appendix Figure 4 As shown, this is a structural schematic diagram of the auxiliary frame 51 in this embodiment. The auxiliary frame 51 also includes a spring assembly 514, which is disposed in the sliding groove 512. When the sliding block 513 slides to the side of the support seat 54, the spring assembly 514 is in a stored state. During use, when the extrusion plate 43 presses against the position of the calibration cylinder 52, the spring assembly 514 is in a stored state until the extrusion plate 43 returns to its original position along with the extrusion piece 3. Then, the spring assembly 514 will release its own elastic force to quickly reset the calibration cylinder 52, which facilitates the conveying of the steel wire after docking.

[0036] From the appendix Figure 4 As shown, the calibration cylinder 52 consists of a rotating cylinder and a locking block. The rotating cylinder is installed between the sliding blocks 513, and the locking blocks are installed at equal intervals on the side of the rotating cylinder. During use, when the steel wire is conveyed in the support seat 54, it will drive the rotating cylinder to rotate synchronously. When the rotating cylinder is squeezed by the extrusion plate 43 and approaches the mating plate 53, the locking block is squeezed and extruded from the outer surface of the steel wire, locking the position of the steel wire.

[0037] From the appendix Figure 5As shown, this is a structural schematic diagram of the extrusion component 3 in this embodiment. The extrusion component 3 includes a movable plate 31, a mating groove 32, and a limiting toothed plate 33. The movable plate 31 is disposed on the upper surface of the base 1. A mating groove 32 is provided on the side of the movable plate 31 near the fixed plate 2. The limiting toothed plate 33 is installed on the surface of the mating groove 32. In use, the fixed plate 2 and the extrusion component 3 have the same structure. By utilizing the mating groove 32 opened inside both and the limiting toothed plate 33 installed in the mating groove 32, the conveyed steel wire is limited and calibrated to ensure stable output of the steel wire. Moreover, the structure and shape of the mating groove 32 itself ensure that when the fixed plate 2 and the extrusion component 3 are close together, the steel wire will not be subjected to excessive extrusion force, which would cause the steel wire to become sheet-like.

[0038] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
