Description

A modular rapid installation and positioning device for grain and oil equipment Technical Field

[0001] This utility model relates to the field of modular assembly technology for grain and oil equipment, and in particular to a modular rapid installation and positioning device for grain and oil equipment. Background Technology

[0002] Modular production is widely used in various industries, including the assembly of conveyor housings commonly used in grain and oil production. Figure 1 shows the housing structure of a scraper conveyor in grain and oil production. The housing is assembled by connecting and assembling multiple rectangular cylinders with flanges at the ends. In the existing technology, when assembling the housing shown in Figure 1, the two parts are first coaxially supported with temporary supports, then brought into axial contact, and finally fixed with multiple bolts to complete the assembly. During the tightening process, each rotating nut needs to be tightened gradually and one by one. For a single bolt and nut, it is also necessary to tighten it multiple times to ensure that the preload of each bolt is equal and that the force is balanced at all points of connection. The assembly process is cumbersome and requires multiple people to cooperate, and the assembly efficiency needs to be optimized.

[0003] To address the aforementioned issues, a modular rapid installation and positioning device for grain and oil equipment is provided. This device can quickly align two assembly modules and then temporarily fix them in place. This allows for the tightening of bolts and nuts in one go, and ensures that the forces at the connection points are evenly distributed after assembly. Assembly can be completed by one person, greatly improving assembly efficiency. Summary of the Invention

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a modular quick installation and positioning device for grain and oil equipment, which effectively solves the problems of cumbersome assembly process, inconvenient operation and low assembly efficiency of grain equipment in the prior art.

[0005] The technical solution includes two frames arranged symmetrically on the left and right sides, with a gap between them; each frame has a clamping unit on the front and rear side walls of its cavity at the end closest to each other; the clamping unit includes a mounting block, which is mounted on the frame, and a swing rod is hinged to the mounting block by a torsion spring. The end of the swing rod away from the mounting block is located in the gap between the two frames, and a top rod is hinged to the end of the swing rod in the gap between the two frames by a torsion spring. The two top rods are arranged in a figure-eight shape.

[0006] There are multiple telescopic cylinders between the two frames, and the extension and retraction of the multiple telescopic cylinders can control the increase or decrease of the interval between the two frames.

[0018] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0019] As shown in Figures 1 to 7, this utility model includes two frames 1, which are arranged symmetrically from left to right and have a gap between them. Each frame 1 has a clamping unit on the front and rear side walls of its cavity at the end closest to each other. Each clamping unit includes a mounting block 2, which is mounted on the frame 1. A swing rod 3 is hinged to the mounting block 2 via a torsion spring. The end of the swing rod 3 away from the mounting block 2 is located within the gap between the two frames 1. A top rod 4 is hinged to the end of the swing rod 3 within the gap between the two frames 1 via a torsion spring. The two top rods 4 are arranged in a V-shape.

[0020] There are multiple telescopic cylinders 5 between the two frames 1, and the telescopic movement of the multiple telescopic cylinders 5 can control the increase or decrease of the interval between the two frames 1.

[0021] To facilitate the movement of the components to be assembled, multiple rollers 6 are provided on the lower side of the cavity of the frame 1.

[0022] In order to install the mounting block 2 and to move the mounting block 2 up and down, thereby adjusting the height of the components to be assembled, a U-shaped plate 7 is fixed on the side wall of the frame 1. The mounting block 2 is placed inside the U-shaped plate 7 and can slide up and down. A vertical and rotatable lead screw 8 is provided inside the U-shaped plate 7. A nut is fixed on the mounting block 2, and the lead screw 8 is screwed onto the nut. When the lead screw 8 is screwed, the nut can drive the mounting block 2 to move up and down.

[0023] To facilitate the horizontal movement of the frame 1, multiple wheels 9 are installed on the lower side plate of the frame 1.

[0024] The telescopic cylinder 5 is an electric cylinder, a pneumatic cylinder, or a hydraulic cylinder.

[0025] It is worth noting that in this design, the center height of mounting block 2 is consistent with the center height of the corresponding module to be assembled. The end of the push rod 4 abuts against the apex of the flange at the end of the module to be assembled, allowing the two modules to be stably and securely clamped together at their ends, achieving the purpose of temporary clamping. Since mounting block 2 can move up and down, this device can also assemble two misaligned housings, which also facilitates the adjustment of the relative positions of the two modules to be assembled.

[0026] In use, push the two modules to be assembled into the two frames 1 respectively, and make initial contact at the ends of the two modules between the two frames 1. During this process, the swing arm 3 does not prevent the two frames 1 from moving towards the middle, as shown in Figure 7. At this time, activate multiple telescopic cylinders 5 to retract simultaneously. The multiple telescopic cylinders 5 drive the two frames 1 to move towards the middle at the same time. During this process, the push rods 4 in the two clamping units on the same frame 1 respectively press against the four corners of the flanges with the assembly parts, until the flanges of the two components to be assembled are pressed together and tightened. When the clamping force between the two flanges reaches the preset value, the telescopic cylinders 5 stop retracting. At this time, the two flanges with the assembly parts can be fixed with multiple bolts to complete the assembly. Finally, the multiple telescopic cylinders 5 extend and return to their original position. At this time, the assembled module can be hoisted and moved away. Of course, the swing arm 3 can also be manually moved to both sides, and then the assembled module can be pulled away from one side. The specific method depends on the site conditions.
