Description

Technical Field

[0001] This utility model relates to the field of waterjet cutting technology, and in particular to a dual-cylinder forced synchronization device for a pneumatic lifting door used for waterjet cutting to prevent splashing. Background Technology

[0002] In the field of high-pressure water jet cutting technology, the pneumatic lifting front door, used to prevent sand and water splashing, is a crucial component. Its lifting action is accomplished by two cylinders working in tandem on the left and right. Traditional pneumatic lifting door systems typically include core components such as a support base, transmission frame, lifting door body, and cylinder body. Its working principle is that the extension and retraction of the cylinder body drives the lifting door body to move up and down, while the transmission frame and support base are responsible for ensuring the stability and accuracy of the lifting door body's movement.

[0003] While existing pneumatic lifting door designs can achieve basic lifting functions, they still have significant shortcomings in practical applications. Firstly, the large installation distance between the left and right cylinders (approximately equal to the width of the front door), combined with pressure differences and manufacturing defects in the cylinders themselves, leads to asynchronous lifting movements, affecting the door's stability. Although some technical solutions attempt to address this issue by optimizing the cylinder's pressure regulating valve, the actual effect is limited because the valve's precision and response speed cannot fully match the dynamic demands of the two cylinders. Furthermore, while the large-area design of existing pneumatic lifting doors can block the large amount of sand and water splashed during high-pressure water jet cutting, it hinders workpiece loading and unloading, impacting operational efficiency.

[0004] In summary, existing pneumatic lifting doors share common shortcomings in solving the problems of cylinder synchronization and dealing with sand and water splashing. This utility model aims to effectively improve the stability and ease of operation of the lifting door through an innovative dual-cylinder forced synchronization device, while ensuring its reliable operation in high-pressure cutting environments. Utility Model Content

[0005] The purpose of this invention is to provide a dual-cylinder forced synchronization device for a pneumatic lifting door used for water jet cutting to prevent splashing, which can overcome the shortcomings of existing lifting doors.

[0006] To achieve the above objectives, a dual-cylinder forced synchronization device for a pneumatic lifting door with anti-splash water jet cutting is provided, including a support base, transmission frames installed at both ends of the support base, a lifting door body slidably connected between the two transmission frames, and a lifting plate fixedly connected to one side wall of each lifting door body near the transmission frame. A chain is installed on the outer wall of the lifting plate, and a cylinder body is installed inside each of the transmission frames. The output end of the cylinder body is fixedly connected to the lifting plate. A long shaft is rotatably connected inside the support base, and a transmission base is fixedly connected to the inner wall of the transmission frame near the support base.

[0007] According to the aforementioned dual-cylinder forced synchronization device for a pneumatic lifting door used for water jet cutting to prevent splashing, each of the transmission frames has a connecting frame fixedly connected to the end away from the support base, through which the device can be fixed to other components.

[0008] According to the aforementioned dual-cylinder forced synchronization device for a pneumatic lifting door used for water jet cutting to prevent splashing, a transmission sprocket is rotatably connected to the end of the transmission base away from the support base. The transmission sprocket meshes with the chain and is used to support one end of the chain.

[0009] According to the aforementioned dual-cylinder forced synchronization device for a pneumatic lifting door used for water jet cutting to prevent splashing, sprockets are fixedly connected to both ends of the long shaft. The long shaft meshes with the chain through the sprockets. When the chain at one end rotates, the sprockets can drive the long shaft to rotate in a forced manner, and the chain on the other side rotates synchronously, thereby forcing the lifting door to rise and fall smoothly.

[0010] According to the aforementioned dual-cylinder forced synchronization device for a pneumatic lifting door used for water jet cutting to prevent splashing, mounting plates are fixedly connected to both sides of the lifting door body. The mounting plates are fixed to the chain, and the arrangement of the mounting plates and the chain allows the chain to be driven as the lifting door body moves up and down.

[0011] This utility model has the following beneficial effects: Compared with existing technologies, this invention effectively solves the problem of asynchrony between the left and right cylinders caused by air pressure fluctuations and differences in cylinder manufacturing processes through a unique dual-cylinder forced synchronization device. During the lifting process, the device utilizes the precise cooperation between the chain and the long shaft to force the left and right cylinders to move in unison, achieving a synchronization accuracy of over 98%, which greatly improves the stability and coordination of the lifting door operation.

[0014] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0015] Reference Figure 1-4 This utility model discloses a dual-cylinder forced synchronization device for a pneumatic lifting door used for water jet cutting with anti-splash function. It includes a lifting plate 1 and cylinder bodies 2. The mounting structure of the lifting plate 1 and cylinder bodies 2 is the core power component of the entire synchronization device. Each cylinder body 2 is fixedly mounted inside a transmission frame 7, and its output end is fixedly connected to the lifting plate 1 via a robust connector. This connection method ensures that the cylinder body 2 can directly drive the lifting plate 1 to perform stable vertical movement during extension and retraction. The cylinder body 2 adopts high-pressure pneumatic technology, featuring rapid response and high-precision control, and can provide sufficient thrust in a short time to enable the lifting plate 1 to achieve smooth lifting and lowering. The installation position of the cylinder body 2 is precisely calculated to ensure that its thrust direction is strictly consistent with the movement direction of the lifting plate 1, thereby reducing lateral forces during movement and avoiding jamming or offset caused by uneven force.

[0016] The transmission mechanism consisting of chain 3 and long shaft 4 is a key component for achieving synchronization of the two cylinders. Chain 3 is installed on the outer wall of the lifting plate 1. One end of chain 3 is connected to the lifting plate 1, and the other end is tightly engaged with the sprocket on the long shaft 4. The long shaft 4 passes through the support seat 9. When the cylinder body 2 drives the lifting plate 1 to rise or fall, chain 3 rotates accordingly, thereby driving the long shaft 4 to rotate. Since the long shaft 4 connects the chains 3 on both sides, the movement of one chain inevitably drives the other chain to move synchronously. This forced synchronization design effectively solves the problem of asynchronous lifting caused by air pressure differences. Chain 3 is made of high-strength alloy steel, possessing good wear resistance and tensile strength, and can withstand high-frequency reciprocating motion for a long time. The connection between the sprocket and the long shaft 4 adopts a precision-machined spline structure to ensure efficient transmission of torque while facilitating disassembly and maintenance.

[0017] The transmission seat 6 is fixedly installed on the inner wall of the transmission frame 7 near the support seat 9. The end of the transmission seat 6 away from the support seat 9 is rotatably connected to the transmission sprocket 601. The transmission sprocket 601 is tightly engaged with the chain 3. When the chain 3 rotates, the transmission sprocket 601 rotates accordingly. The transmission seat 6 is equipped with a high-precision bearing to ensure that the rotation of the transmission sprocket 601 is smooth and without obvious gaps, effectively avoiding synchronization errors caused by loose sprockets. The connection between the transmission seat 6 and the transmission frame 7 adopts a modular design, which facilitates quick adaptation and replacement on different specifications of lifting doors.

[0018] The connection and guiding structure between the support base 9 and the transmission frame 7 are fundamental to ensuring the stability of the entire device. The support base 9, serving as the base of the entire device, is made of high-strength cast iron, possessing excellent shock absorption and deformation resistance. Both ends of the support base 9 are connected to the transmission frame 7 through high-precision machined mounting holes. The tolerance of the mounting holes is controlled within a very small range to ensure the installation accuracy of the transmission frame 7. The transmission frame 7 has a guide groove inside. The lifting door body 101 achieves smooth vertical sliding by cooperating with the guide groove via a slider. The surface of the guide groove undergoes special treatment, possessing a low coefficient of friction and high durability, maintaining good guiding performance during long-term use. The top and bottom of the transmission frame 7 are equipped with sealing structures to prevent sand and water generated during cutting from splashing into the transmission components, extending the service life of the device.

[0019] The connecting frame 8 is fixedly installed at the end of the transmission frame 7 away from the support base 9. Its main function is to enhance the structural strength and stability of the entire device. The connecting frame 8 adopts a triangular frame structure. This geometry has extremely high stability and can effectively distribute stress from all directions, reducing the risk of deformation caused by external impact. The connection between the connecting frame 8 and the transmission frame 7 adopts a dual method of multi-point welding and bolt fastening to ensure the firmness and reliability of the connection. The surface of the connecting frame 8 is coated with an anti-corrosion coating to adapt to the humid and dusty working environment of the waterjet cutting workshop and prevent metal corrosion caused by long-term exposure.

[0020] Through the detailed description of the above embodiments, each key component and its functional characteristics of this utility model have been fully demonstrated. These components cooperate with each other to form a highly efficient and stable dual-cylinder forced synchronization device, effectively solving the problem of asynchronous lifting in the prior art and improving the performance of pneumatic lifting doors during high-pressure water jet cutting. At the same time, the structural design of this utility model fully considers the needs of actual working conditions and the convenience of later maintenance, possessing good practicality and promotional value.

[0021] Unless otherwise specified, the constituent units of this utility model are obtained from conventional commercial channels or manufactured by conventional methods. Their specific structure, working principle, and possible control methods and spatial arrangement methods can adopt conventional choices in the field and should not be regarded as the innovation of this utility model. This is understandable to those skilled in the art, and this utility model patent will not be further elaborated in detail.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
