Description

Technical Field

[0001] This utility model relates to the field of industrial pipeline corrosion protection technology, specifically to a multifunctional elbow rubber-lined auxiliary workbench. Background Technology

[0002] Rubber-lined elbows are an industrial pipeline corrosion protection technology. It involves bonding a layer of chemically stable rubber to the inner wall of a metal elbow (usually carbon steel or cast iron), completely isolating the corrosive medium being transported from the metal body. This achieves corrosion resistance, wear resistance, scale prevention, and extended service life. High-quality rubber-lined elbows can have a service life of 5-10 years or even longer. The process includes sandblasting for rust removal, rubber coating, rubber sheet cutting, rubber sheet lamination, and vulcanization. In the rubber sheet lamination process, to facilitate manual operation, the workpiece needs to be placed on a flat surface at a certain height. Currently, there are two main methods: one is to place it directly on a large workbench. However, this lacks a fixed limiting device for the elbow, relying solely on its own weight. This makes it prone to tipping over during elbow hoisting and rotation, posing a significant safety risk. Furthermore, the large workbench makes it inconvenient for operators and can easily lead to quality problems. Secondly, the use of dedicated workbenches is problematic. Due to the wide variety of elbow specifications and models, with a standard diameter range of 108-530mm, each specification requires a separate workbench, resulting in a large number of workbench specifications and models, leading to high investment costs and large space requirements. Therefore, to address the aforementioned issues, it is necessary to propose a multi-functional elbow lining auxiliary workbench that is safer, more convenient to operate, can be used for auxiliary work with elbows of various diameters, improves work efficiency, has lower costs, and occupies less space. Summary of the Invention

It solves the problems of high safety risks, easy quality problems, high investment costs, and large space occupation in the current commonly used operations, effectively improving work efficiency, reducing the investment in workbench, and reducing the workshop storage area.

[0011] This utility model's inverted side stop assembly, in conjunction with the inverted load-bearing assembly, can limit and fix elbows of different specifications. The inverted load-bearing assembly uses a set of movable bottom blocking square steel for fixing and limiting. The parallel guide rail is designed with a T-slot to allow for position adjustment of the two bottom blocking square steels. After adjustment, the bolts are fixed to the bottom blocking square steels through the round holes of the bolts. The inverted side stop of the inverted side stop assembly can be adjusted and moved, thereby limiting elbows of different specifications on both sides. The inverted load-bearing assembly, in conjunction with the inverted side stop assembly, provides auxiliary fixation for the inverted elbows, facilitating the next step of the process.

[0014] The specific embodiments of this utility model are described below to enable those skilled in the art to understand this utility model. However, it should be understood that this utility model is not limited to the scope of the specific embodiments. For those skilled in the art, as long as various changes are within the spirit and scope of this utility model as defined and determined by the appended claims, these changes are obvious. All utility model creations utilizing the concept of this utility model are within the scope of protection.

[0015] like Figure 1 and Figure 2As shown, the multi-functional elbow lining auxiliary workbench frame includes a frame 1, on which a forward placement platform 11 and an inverted placement platform 12 are installed. The forward and inverted placement stations for the elbow workpiece 6 are designed as one unit. The left forward placement platform 11 is used for forward placement of the elbow workpiece 6. The overall design concept of the forward placement station is to use symmetrical multiple partitions for support. The spacing of the partitions is designed to accommodate elbows of different diameters. Sliding side guard components are designed on both sides, allowing the elbow workpiece 6 to be adjusted according to its diameter to ensure effective protection. The right inverted placement platform 12 is used for inverting the elbow workpiece 6. The overall concept is that after the elbow is inverted, a bottom blocking square steel is designed to prevent displacement of the elbow's axis. The blocking square steel can be adjusted horizontally and symmetrically to adapt to the positioning requirements of elbows of different diameters. Sliding side guard components are designed on both sides, allowing the side guard components to be adjusted according to the elbow's diameter to ensure effective protection. To facilitate the operation of lining insertion and patch bonding, two working surfaces at different heights are designed on the left and right sides.

[0016] like Figure 3 and Figure 4 As shown, a forward-positioning platform 11 is equipped with a forward-positioning side-blocking assembly 2 and a forward-positioning support assembly 3. The forward-positioning side-blocking assembly 2 is used to limit the left and right sides of the forward-positioned bent workpiece 6, and the forward-positioning support assembly 3 is used to support the forward-positioned bent workpiece 6. The forward-positioning side-blocking assembly 2 includes a first side-blocking slide rail 22, two forward-positioning sliders set on the first side-blocking slide rail 22, and a forward-positioning side block 21 fixed on each forward-positioning slider. Each forward-positioning slider is provided with a first fixing screw 23, which is located on the top of the forward-positioning slider. The forward-positioning support assembly 3 includes a U-shaped support frame 31. Two symmetrical central support plates 32 are provided inside the support frame 31.

Specifically, the upright elbow workpiece 6 is placed on the corresponding support frame 31, the middle support plate 32, and the side support plate 33. Then, by adjusting and fixing the positions of the two upright sliders, the two upright side stops 21 are driven to clamp and limit the sides of the elbow workpiece 6. Thus, the upright side stop assembly 2 and the upright bearing assembly 3 work together to achieve the working limit of the upright elbow workpiece 6, which facilitates the next process of the upright elbow workpiece 6.

[0017] like Figure 5 As shown, the inverted platform 12 is equipped with an inverted side stop assembly 4 and an inverted support assembly 5. The inverted side stop assembly 4 is used to limit the left and right sides of the inverted elbow workpiece 6, and the inverted support assembly 5 is used to support the inverted elbow workpiece 6. The inverted side stop assembly 4 includes two second side stop slide rails 42, each second side stop slide rail 42 is equipped with an inverted slider, each inverted slider is fixedly connected with an inverted side stop 41, and each inverted slider is equipped with a second fixing screw 43, which is located on the top of the inverted slider. Figure 6 and Figure 7As shown, the inverted bearing assembly 5 includes two parallel guide rails 51 and two bottom blocking square steels 52 arranged parallel to the two parallel guide rails 51. The parallel guide rails 51 are provided with T-shaped grooves that cooperate with T-shaped bolts 53. The bottom blocking square steels 52 are provided with bolt holes that cooperate with T-shaped bolts 53. Each bottom blocking square steel 52 is installed on the two parallel guide rails 51 through two T-shaped bolts 53. Specifically, first, based on the bottom distance of the inverted elbow workpiece 6, adjust the spacing of the two bottom blocking square steels 52 to match, and adjust the T-bolts 53 to lock and limit the two bottom blocking square steels 52. Then, place the inverted elbow workpiece 6 between the two bottom blocking square steels 52. Then, by adjusting and fixing the positions of the two inverted sliders, drive the two second side rails 42 to clamp and limit the sides of the inverted elbow workpiece 6. Thus, the inverted side rail assembly 4 and the inverted bearing assembly 5 work together to achieve the working limit of the upright elbow workpiece 6, which facilitates the next process of the upright elbow workpiece 6.

[0018] In this embodiment, the top of the first side rail 22 and the top of the second side rail 42 are provided with inverted trapezoidal protrusions, and the bottom of the upright slider and the bottom of the inverted slider are provided with inverted trapezoidal grooves that cooperate with the inverted trapezoidal protrusions.

[0019] In this embodiment, the bottom of the support frame 31 is provided with an opening for the first side rail 22 to cooperate with, and the two upright side rails 21 can slide left and right within the support frame 31, such as... Figure 2 .
