Description

Technical Field

[0001] This utility model relates to the field of workbench technology, and in particular to a shell-and-tube heat exchanger assembly workbench. Background Technology

[0002] In the manufacturing process of shell-and-tube heat exchangers, the assembly stage is a key process connecting design drawings and finished products. Its quality and efficiency directly determine the market competitiveness of the product. Currently, shell-and-tube heat exchangers are widely used in petrochemical, energy and power industries. Customers have increasingly diverse requirements for equipment specifications (such as tube bundle diameter, shell length, interface position, etc.), requiring the production line to have rapid response capabilities. Workers use work platforms, but due to the variety of heat exchanger specifications, the size of the platforms that workers need to assemble varies. However, in actual use, the workbench surface is mostly a fixed structure, which cannot quickly adapt to the assembly needs of different models of components, resulting in long time consumption and easy reduction in assembly accuracy due to positioning errors.

[0003] Therefore, in order to address this problem, this utility model provides a shell-and-tube heat exchanger assembly workbench. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a shell-and-tube heat exchanger assembly workbench, comprising a support platform, a support frame symmetrically and movably engaged at the bottom of the support platform, an electric push rod disposed at the bottom of the support platform, a push frame fixedly connected to one end of the electric push rod, casters symmetrically disposed at the bottom of the push frame, a replaceable platform symmetrically and movably engaged at the top of the support platform, a locking thread rod being threadedly connected between the support platform and the replaceable platform, limit rods symmetrically disposed on both sides of the support frame, and movable seats disposed at both ends of the push frame, the movable seats being movably connected to the limit rods.

[0006] Preferably, the bottom of the replaceable platform is provided with a docking groove, and the top of the support platform is provided with an installation groove, wherein the docking groove matches the installation groove.

[0007] Preferably, the bottom of the support frame is provided with a patterned groove for anti-slip purposes.

[0008] Preferably, the top of the support frame is provided with a splicing seat, and the bottom of the support platform is provided with a slot that matches the splicing seat.

[0009] Preferably, the bottom of the push frame is symmetrically provided with grooves, which are used to reduce weight.

[0010] Preferably, the support platform is provided with symmetrical push grooves on both sides, and the push grooves are used for transportation.

[0011] Compared with the prior art, this utility model provides a shell-and-tube heat exchanger assembly workbench, which has the following advantages:

[0012] 1. This shell-and-tube heat exchanger assembly workbench, through its modular design of support platform and replaceable tabletop, as well as the quick-connect structure of support frame and support platform, enables the workbench to be quickly adapted when assembling heat exchangers of different specifications. At the same time, the moving mechanism with electric push rod driving universal wheels for lifting and lowering, along with the push groove design, allows the workbench to efficiently switch between fixed operation and flexible handling modes, significantly shortening equipment adjustment time and improving production efficiency.

[0013] 2. The assembly workbench for this shell-and-tube heat exchanger features an anti-slip design with textured grooves on the bottom of the support frame, effectively improving its resistance to lateral slippage in a fixed state and reducing the risk of tipping over due to slippery surfaces or vibrations. Furthermore, the push frame utilizes a guide structure with limit rods and movable seats, along with a lightweight design featuring grooves, to optimize the mechanical properties of moving parts, ensuring stability during the lifting and lowering of the casters. These structural improvements collectively enhance the safety and reliability of the workbench during assembly, handling, and long-term use, reducing potential equipment malfunctions and operational accidents.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

[0020] Reference Figures 1-3 A shell-and-tube heat exchanger assembly workbench includes a support platform 1. Support frames 2 are symmetrically and movably connected to the bottom of the support platform 1 via bolts or snap-fit ​​structures to ensure stability. An electric push rod 3 is installed at the bottom of the support platform 1. One end of the electric push rod 3 is fixedly connected to a push frame 4. Universal wheels 5 are symmetrically installed at the bottom of the push frame 4. When the electric push rod 3 extends, the push frame 4 drives the universal wheels 5 to descend, allowing the workbench to move. When the electric push rod 3 retracts, the universal wheels 5 rise, the support frame 2 contacts the ground, and the workbench is fixed, providing stable support. A replaceable platform plate 8 is symmetrically and movably attached to the top of the platform 1. Locking threaded rods 9 are threadedly connected between the support platform 1 and the replaceable platform plate 8 to fix the replaceable platform plate 8. Limiting rods 6 are symmetrically arranged on both sides of the support frame 2. Movable seats 7 are provided at both ends of the push frame 4. The movable seats 7 are movably connected to the limiting rods 6 to ensure the stability of the push frame 4 during movement. Through the above implementation method, the movement and fixing functions of the workbench are realized. Moreover, the design of the replaceable platform plate 8 allows the workbench to adapt to the assembly requirements of heat exchangers of different specifications, improving the flexibility and applicability of the workbench.

[0021] The replaceable table plate 8 has a docking groove 801 at its bottom. The shape and size of the docking groove 801 match the mounting groove 101 on the top of the support platform 1. When installing the replaceable table plate 8, the docking groove 801 is aligned with the mounting groove 101 and inserted. Then, the replaceable table plate 8 is fixed to the support platform 1 by locking the threaded rod 9. The matching design of the docking groove 801 and the mounting groove 101 ensures accurate docking and stable connection between the replaceable table plate 8 and the support platform 1, improving the assembly accuracy and stability of the worktable.

[0022] The bottom of the support frame 2 is provided with a patterned groove 201. The shape and depth of the patterned groove 201 are optimized to increase the friction between the support frame 2 and the ground, thereby playing an anti-slip role. The design of the patterned groove 201 effectively improves the anti-slip performance of the support frame 2, ensures the stability of the workbench in a fixed state, and reduces safety hazards caused by wet or uneven ground.

[0023] The top of the support frame 2 is equipped with a splicing seat 202. The shape and size of the splicing seat 202 match the slot opened at the bottom of the support platform 1. When installing the support frame 2, the splicing seat 202 is aligned with the slot and inserted. Then, the support frame 2 is fixed to the support platform 1 by bolts or buckles. Through the matching design of the splicing seat 202 and the slot, a quick and stable connection between the support frame 2 and the support platform 1 is achieved, which improves the assembly efficiency and stability of the workbench.

[0024] Among them, the bottom of the push frame 4 is symmetrically provided with a groove 401. The shape and size of the groove 401 have been optimized to reduce the weight of the push frame 4 while maintaining its structural strength. The design of the groove 401 effectively reduces the weight of the push frame 4, reduces the load on the electric push rod 3, and improves the moving efficiency and stability of the worktable. At the same time, the design of the groove 401 also facilitates heat dissipation and reduces material usage, thus reducing costs.

[0025] The support platform 1 is symmetrically provided with push grooves 10 on both sides. The shape and size of the push grooves 10 are optimized to facilitate the operator to move the workbench to the designated position. The design of the push grooves 10 facilitates the handling of the workbench, enabling the operator to easily move the workbench to the designated position, thereby improving work efficiency and safety. At the same time, the design of the push grooves 10 also increases the handling flexibility of the workbench and adapts to the handling needs in different scenarios.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
