Description

Technical Field

[0001] This utility model belongs to the technical field of frame pre-tensioned tie rods, specifically relating to a segmented pre-tensioned tie rod structure and fixing device. Background Technology

[0002] The frames of stamping machinery can be broadly divided into integral frames and modular frames. Integral frames are not suitable for transportation, so the stamping machinery in the manufacturing industry now tends to use modular frames.

[0003] For stamping machinery with a modular frame structure, on-site assembly is required after transportation to the user's factory. The overall frame of the modular machine consists of beams and supports, typically secured using tie rods. However, existing tie rod structures use a long tie rod that passes through the mating holes of each beam and the intermediate supports for fastening. This method has several drawbacks. For example, during installation, the long tie rod needs to be hoisted to fit into the mating holes of each beam and the intermediate supports, which requires a certain factory height; insufficient height can lead to installation difficulties. Furthermore, once the long tie rod is released after installation, the entire structure loses its stability, making it impossible to maintain or replace individual sections of the structure.

[0004] Therefore, it is particularly important to develop a new type of tie rod structure to solve the above problems. Utility Model Content

[0005] The purpose of this application is to overcome the shortcomings of the prior art and provide a segmented pre-tensioned tie rod structure and fixing device, specifically adopting the following technical solution:

[0006] On the one hand, this application provides a segmented preloaded tie rod structure, including:

[0007] The frame, the first tie rod, the second tie rod, the first fixing component, the second fixing component, and the lifting mechanism;

[0008] The frame includes a first beam, a second beam, and support columns;

[0009] The first tie rod is provided with a first mating structure, and the second tie rod is provided with a second mating structure;

[0010] The first beam is provided with a through hole that can accommodate the first tie rod;

[0011] The second beam is provided with a through hole that can accommodate the second tie rod;

[0012] A third mating structure, matching the first mating structure, is provided above the support column;

[0013] A fourth mating structure, matching the second mating structure, is provided below the support column;

[0014] The first tie rod can pass through the through hole of the first beam and connect with the support column through the first and third mating structures;

[0015] The second tie rod can pass through the through hole of the second beam and connect with the support column through the second and fourth mating structures.

[0016] The lifting mechanism and the first fixing member are capable of lifting and fixing the first pull rod;

[0017] The second fastener can secure the second tie rod.

[0018] As some sub-solutions of the above technical solution, the lifting mechanism includes a lifting structure support, a lifting structure cylinder, a lifting structure piston, and a lifting structure fixing component.

[0019] As a sub-solution of the above technical solution, the lifting structure support is wrapped around the outside of the first tie rod, with its bottom end contacting the top end of the first beam and its top end contacting the lifting structure cylinder.

[0020] As some sub-solutions of the above technical solutions, the lifting structure cylinder and the lifting structure piston are complementary structures to form a lifting device powered by hydraulic or pneumatic pressure.

[0021] As some sub-solutions of the above technical solution, the lifting structure fixing member is provided with a structure that cooperates with the top end of the first pull rod so that the two can form a connection; the lifting structure piston is also provided with a through hole, and the lower end of the lifting structure fixing member can be embedded in the through hole of the lifting structure piston; the lifting structure fixing member is also provided with an extension structure so that the lifting structure fixing member can be lifted by the lifting structure piston.

[0022] As some sub-solutions of the above technical solution, a connecting plate is also included, which can fix the support column and the first beam from the outside.

[0023] As some sub-solutions of the above technical solution, the first fixing element is a nut, and the first tie rod is provided with a matching thread; the second fixing element is a nut, and the second tie rod is provided with a matching thread.

[0024] As a sub-solution of the above technical solution, the lifting mechanism is also provided with a lifting window, through which the first fixing member can be adjusted.

[0025] As some sub-solutions of the above technical solution, the first mating structure and the third mating structure are matching threaded fastening structures; the second mating structure and the fourth mating structure are matching threaded fastening structures.

[0026] On the other hand, this application also provides a fixing device including the above-described segmented pre-tensioned tie rod structure.

[0027] The beneficial effects of this application are as follows:

[0028] The segmented pre-tensioned tie rod structure allows the frame to be partially pre-assembled at the factory according to requirements, thereby improving the efficiency of subsequent on-site deployment. When the components need to be transported to the site for installation in a completely dispersed manner, the segmented pre-tensioned tie rod structure allows the assembly process to only tighten two shorter tie rods, resulting in a low lifting height and avoiding many restrictions on the height of the factory during installation. On the other hand, its segmented structure allows for the loosening of some tie rods while preventing the overall structure from completely losing its fixation, making installation and maintenance easier.

[0040] Combination Figure 1 The specific implementation of the segmented pre-tensioned tie rod structure and fixing device provided by this utility model is described here:

[0041] First, this application provides a segmented preloaded tie rod structure, comprising:

[0042] The frame, the first tie rod 202, the second tie rod 403, the first fixing member 201, the second fixing member 402, and the lifting mechanism;

[0043] The frame includes a first beam 101, a second beam 401, and a support column 102;

[0044] The first tie rod 202 is provided with a first mating structure, and the second tie rod 403 is provided with a second mating structure;

[0045] The first beam 101 is provided with a through hole that can accommodate the first tie rod 202;

[0046] The second beam 401 is provided with a through hole that can accommodate the second tie rod 403;

[0047] A third mating structure matching the first mating structure is provided above the support column 102;

[0048] A fourth mating structure, which is matched with the second mating structure, is provided below the support column 102;

[0049] The first tie rod 202 can pass through the through hole of the first beam 101 and is connected to the support column 102 through the first and third mating structures;

[0050] The second tie rod 403 can pass through the through hole of the second beam 401 and connect with the support column 102 through the second and fourth mating structures.

[0051] The lifting mechanism and the first fixing member can lift and fix the first pull rod 202;

[0052] The second fastener can fix the second tie rod 401.

[0053] The first fixing member 201 is a nut, and the first pull rod 202 is provided with a matching thread; the second fixing member 402 is a nut, and the second pull rod 403 is provided with a matching thread.

[0054] After the various groups are transported to the installation site in a decentralized manner, the support column 102 and the second tie rod 403 are first assembled. In this specific embodiment, the second and fourth mating structures that match between the two are mutually matched threaded structures. Then, the assembled support column 102 is hoisted above the second beam 401, and the second tie rod 403 at the bottom of the support column 102 is aligned with the through hole of the second beam 401. Then, it is slowly lowered for assembly, and the second fastener 402 is used to fasten it. In this specific embodiment, the second fastener 402 is a matching nut with an outer diameter larger than the diameter of the through hole of the second beam 401. By fastening the second fastener 402, the second tie rod 403, the second fastener 402, the second beam 401 and the support column 102 form a stable assembly structure.

[0055] Subsequently, the first beam 101 is hoisted above the support column 102, and its through hole is aligned with the third mating structure at the top of the support column 102; the support column 102 and the first beam 101 are fixedly connected using the connecting plate 501 and matching screws, so that the two are relatively stable and it is convenient to hoist the first tie rod 202 and the lifting mechanism in the future.

[0056] Then, the first tie rod 202 is hoisted and placed above the through hole of the first beam 101, so that the first mating structure and the third mating structure are aligned. In this specific embodiment, the first mating structure and the third mating structure are mutually matched threaded fastening structures. Then, they are tightened so that the first tie rod 202 and the first beam 101 are stably assembled.

[0057] Subsequently, the first fixing member 201 is hoisted onto the top of the first pull rod 202 and the first fixing member 201 is tightened; in this specific embodiment, the first fixing member 201 is a nut, and the top of the first pull rod 202 has a matching threaded structure.

[0058] Subsequently, the lifting mechanism is installed. The lifting mechanism includes a lifting structure support 301, a lifting structure cylinder 302, a lifting structure piston 303, and a lifting structure fixing member 304. The lifting structure support 301 surrounds the first pull rod 202, with its bottom end contacting the top end of the first beam 101 and its top end contacting the lifting structure cylinder 302. The lifting structure cylinder 302 and the lifting structure piston 303 are mutually complementary structures, forming a lifting device powered by hydraulic or pneumatic pressure. The lifting structure fixing member 304 has a structure that mates with the top end of the first pull rod 202, allowing them to connect. The lifting structure piston 303 also has a through hole, into which the lower end of the lifting structure fixing member 304 can be inserted. The lifting structure fixing member 304 also has an extension structure, allowing it to be lifted by the lifting structure piston 303.

[0059] After the lifting machine is hoisted into place, the lifting structure fixing component 304 and the first pull rod 202 are connected by a matching threaded structure. By tightening the lifting structure fixing component 304, its outer structure is brought into close contact with the lifting structure cylinder 302. The lifting structure support component 301 is supported on the first beam 101. At this time, the hydraulic power lifting device composed of the lifting structure cylinder 302 and the lifting structure piston 303 is activated. The rise of the lifting structure piston 303 applies an upward force to the lifting structure fixing component 304, thereby causing the first pull rod 202 connected to the lifting structure fixing component 304 to rise and tighten the first beam 101 and the support column 102. At this time, a gap will appear between the first fixing component 201 and the first beam 101. By using a tool through the lifting window provided by the lifting mechanism, the first fixing component 201 is tightened, thus completing one pre-tightening assembly. This cycle is repeated until the required pre-tightened pull rod structure is achieved.

[0060] On the other hand, this application also provides a fixing device including the above-mentioned segmented pre-tensioned tie rod structure.

[0061] Although the description of this utility model has been quite detailed and particularly of several described embodiments, it is not intended to limit it to any of these details or embodiments or any particular embodiment, but should be considered as providing a broad possible interpretation of the claims by referring to the appended claims and taking into account the prior art, thereby effectively covering the intended scope of this utility model. Furthermore, the utility model has been described above with respect to embodiments foreseeable by the inventors for the purpose of providing a useful description, and non-substantial modifications to the utility model that have not yet been foreseen may still represent equivalent modifications to the utility model.
