Description

Technical Field

[0001] This invention relates to the field of mechanical manufacturing and auxiliary assembly equipment technology, and more specifically, to a device and method for using a four-tube bundle. Background Technology

[0002] Currently, most existing four-tube bundles are assembled manually. The mounting holes for the bundle structure are deep holes, which ensures that the external dimensions are not affected while ensuring that the bundle force meets the usage requirements. When torque is applied, torsional deformation is easily generated. Often, after one side is tightened, the other three directions have already been displaced, making it difficult to guarantee assembly accuracy. In addition, due to the three-dimensional spatial structure of the bundled four-tube bundle, the measurement of spatial shape and position dimensions becomes complicated and is not easy to measure with simple tools such as calipers.

[0003] In summary, at least one of the following technical problems exists:

[0004] The assembly is done manually. The mounting holes for the bundled structure are deep holes, which ensures that the external dimensions are not affected and that the bundled force can meet the usage requirements. When torque is applied, torsional deformation is likely to occur. Often, after one side is tightened, the other three directions have already been displaced, making it difficult to guarantee assembly accuracy.

[0005] The three-dimensional spatial structure of the clustered four-tube structure makes the measurement of spatial dimensions complex and difficult to perform with simple tools such as calipers. Summary of the Invention

[0006] The main objective of this invention is to provide a device and method for bundling four-tube structures, addressing the following technical issues: In the prior art, manual assembly is used, and the bundling structure requires deep holes for mounting. While this ensures that the external dimensions are not affected, the bundling force is sufficient for the application requirements. However, when torque is applied, torsional deformation easily occurs, often resulting in displacement in the other three directions after one side is tightened, making it difficult to guarantee assembly accuracy. Furthermore, the three-dimensional spatial structure of the bundled four-tube structure complicates the measurement of spatial dimensions, making it difficult to measure using simple tools such as calipers.

[0007] To achieve the above objectives, according to one aspect of the present invention, a device for bundling four-tube cylinders is provided, comprising:

[0008] The columns are arranged symmetrically in pairs.

[0009] The first reinforcing tube is disposed between oppositely arranged columns;

[0010] The second reinforcing tube is arranged perpendicularly to the direction of the first reinforcing tube between the opposing columns;

[0011] A loading beam is provided at the upper end of the column;

[0012] A base, wherein the base is disposed at the lower end of the column;

[0013] A measurement auxiliary frame is provided on the side wall of the column;

[0014] A measuring ruler, which is connected to a measuring auxiliary frame; and

[0015] The first load-bearing beam is mounted on a column on one side.

[0023] Preferably, the loading beam is located at the top of the column, sealing the upper opening, and applies a loading force to the vertical direction of the four-tube assembly through screws, so that it does not shift during the assembly process and meets the vertical accuracy requirements of the four-tube assembly. In conjunction with the horizontal limiting of the inner side of the U-shaped welded frame of the load-bearing structure, the vertical and horizontal accuracy of the four-tube assembly meets the assembly accuracy requirements.

[0024] Preferably, the first limiting block is used to restrict the horizontal position of the four-cylinder body. When the cylinder is installed, a screw is removed and turned outward to make room for the cylinder to enter. After it is fully installed, it is rotated back to serve as a limiting surface. The second limiting block is located in the middle of the U-shaped welded frame. The second limiting block is positioned with the frame by a pin.

The second limiting block is removed when the cylinder is installed or lifted out.

[0025] Preferably, the measuring tape measures the length of the four-tube cylinder after it is installed in place.

[0026] According to another aspect of the present invention, a method of using an apparatus for four-tube bundled assembly is provided, comprising:

[0027] Step 1: Remove the loading beam, rotate the first limiting block outwards, and remove the second limiting block;

[0028] Step 2: Place the cylinder body on the clustering device according to the front-to-back and quadrant relationship requirements of the assembly.

[0029] Step 3: Start bundling. Rotate the two upper parts of the first limiting block inwards and push the cylinder backwards so that the cylinder mating surface fits with the mating surface of the first limiting block. Install the loading beam. Use the bundling parts and standard parts to assemble the four-cylinder bundle.

[0030] Step 4: Remove the loading beam as in Step 1, rotate the two upper parts of the first limiting block outwards, push the bundled cylinder forward to facilitate the removal of the second limiting block, lift the assembled four-unit cylinder out using the hook, restore the device to its original state, and complete the bundled assembly process.

[0031] The technical solution of this invention has the following technical effects:

[0032] By employing frame limiting, limiting block limiting, and loading beam clamping operations, the assembled four-unit cylinder meets the precision requirements for filling, transportation, and maintenance, facilitating efficient assembly. Furthermore, through appropriate size selection, this invention ensures both good clamping effect and ease of carrying and use. Simultaneously, the device is small in size, easy to install and disassemble, and convenient to carry. Attached Figure Description

Detailed Implementation

[0042] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0043] like Figures 1 to 6As shown, this embodiment of the invention provides a device for a four-tube bundle, including columns 1, which are symmetrically arranged in pairs; first reinforcing tubes 4, which are arranged between oppositely arranged columns 1; second reinforcing tubes 12, which are arranged perpendicular to the direction of the first reinforcing tubes 4 between oppositely arranged columns 1; loading beams 3, which are arranged at the upper end of columns 1; bases 9, which are arranged at the lower end of columns 1; and a measuring auxiliary frame 6, which is arranged on the side wall of columns 1; and a measuring... Ruler 7, the measuring ruler 7 is connected to the measuring auxiliary frame 6; first bearing beam 2, the first bearing beam 2 is set on one side column 1; second bearing beam 8, the second bearing beam 8 is set on the other side column 1; first limiting block 13 and second limiting block 14, the first limiting block 13 and the second limiting block 14 are respectively set on the column 1. The present invention is applicable to four-tube bundles, which are four separate tube bundles assembled together as a module, which is convenient for filling, transportation and maintenance. The accuracy of the four-tube bundle has a great impact on the subsequent use process.

[0044] The load-bearing structure of the four-tube bundle device is mainly a U-shaped welded frame. The inner surfaces of the frame, the bottom surface is the load-bearing beam, and the sides are the inner surfaces of the vertical surfaces, which serve as the docking surface of the four-tube bundle and the reference surface for measuring the shape and position dimensions. The lower part of the frame is equipped with a raised column 1 to meet the ergonomic assembly requirements. The lower part of the column 1 can be equipped with rollers or casters as needed for easy turnover and transportation. The load-bearing beam is located at the bottom of the U-shaped welded frame, serving as the main support structure and lower reference surface of the four-tube bundle. The load-bearing structure is equipped with corresponding reinforcing tubes as needed to stabilize the overall welded frame and prevent frame deformation.

[0045] In this embodiment, the columns 1 serve as vertical supports. The columns 1 are arranged symmetrically in pairs, and there are four columns 1 in total. The four columns 1 are arranged vertically. There are also four first reinforcing tubes 4. The four first reinforcing tubes 4 are arranged symmetrically and parallelly in pairs on the columns 1. The four columns 1 are respectively supported at the four corners of the frame to achieve vertical support.

[0046] In this embodiment, the first reinforcing tube 4 is used to provide horizontal support for the frame. The first reinforcing tube 4 is disposed between oppositely arranged columns 1, and a baffle 11 is provided at the connection between the first reinforcing tube 4 and the column 1. The first reinforcing tube 4 is horizontally arranged along the length of the frame, and both ends of the first reinforcing tube 4 are fixedly connected to the column 1. A vertical connecting column is also provided between the first reinforcing tubes 4. The second reinforcing tube 12 provides front-to-back horizontal support for the frame. The second reinforcing tube 12 is disposed perpendicular to the direction of the first reinforcing tube 4 between oppositely arranged columns 1.

[0047] In this embodiment, a loading beam 3 is installed at the upper end of the column 1. The upper end of the loading beam 3 is equipped with a hook 5, which consists of two nuts (one large and one small) and a long screw matching the small nut. A U-shaped ring is formed by bending steel bars according to the width of the hanging point, and the two nuts are welded to the top of the U-shaped ring. The loading beam 3 is located at the top of the column 1, sealing the upper opening. The screw provides a loading force in the vertical direction to the four-tube structure, preventing displacement during assembly and meeting the vertical accuracy requirements of the four-tube structure. Combined with the horizontal limiting function of the inner side of the U-shaped welded frame of the load-bearing structure, the vertical and horizontal accuracy of the four-tube structure meets the assembly accuracy requirements. Specifically, the loading beam 3 is located at the top of the U-shaped welded frame of the load-bearing structure, sealing the upper opening. Four screws provide a loading force in the vertical direction to the four-tube structure, preventing displacement during assembly and meeting the vertical accuracy requirements. Combined with the horizontal limiting function of the inner side of the U-shaped welded frame of the load-bearing structure, the vertical and horizontal accuracy of the four-tube structure meets the assembly accuracy requirements. Specifically, the lifting buckle 5 is used as a lifting tool. Since the width of the cylinder's hanging point exceeds the size of the standard lifting buckle 5, a separate lifting buckle 5 was designed and used after load testing. The lifting buckle 5 consists of two nuts, one large and one small, and a long screw that matches the small nut. A U-shaped ring is bent from steel bars according to the width of the hanging point. The two nuts are welded to the top of the U-shaped ring, ensuring that the top of the inner surface of the nuts is at the same height and that the two nuts are evenly stressed. The long screw is passed through the large nut and screwed onto the small nut to form a matching lifting buckle 5. There are four in total, used to lift the four corners of the cylinder. During turnover and transportation, the lifting buckles 5 are placed together in a canvas and tied to the reinforcing tube to prevent loss.

[0048] In this embodiment, the base 9 is used to support the column 1, and the base 9 is located at the lower end of the column 1; the base 9 is provided with a threaded hole, which is used to cooperate with the stud of the universal wheel to facilitate movement.

[0049] In this embodiment, the measuring auxiliary frame 6 is used to fix the measuring ruler 7, and the measuring auxiliary frame 6 is set on the side wall of the column 1; the measuring ruler 7 is connected to the measuring auxiliary frame 6; the measuring ruler 7 detects the length of the four-section cylinder after installation. The measuring ruler 7, as a separate component, detects the length of the four-section cylinder after installation. When detecting at the front end, it measures the distance from the contact surface with the first limiting block 13 to the front end of the cylinder to ensure that it does not exceed the height limit and does not affect the opening and closing of the manhole cover after the four-section cylinder is filled; when measuring at the rear end, the measuring ruler 7 ensures that the cylinder does not exceed the required total length. To accommodate the measurement at the rear end, an auxiliary measuring frame is added to the supporting frame. The measuring ruler 7 is packaged in a canvas bag, and during transportation, the canvas bag is tied to the reinforcing tube to prevent loss.

[0050] In this embodiment, the first bearing beam 2 is used as the reference surface at the bottom of the cylinder, and the first bearing beam 2 is set on one side column 1; the first bearing beam 2 and the second bearing beam 8 are the support structure and lower reference surface of the four-section cylinder, and the second bearing beam 8 is set on the other side column 1.

[0051] In this embodiment, a first limiting block 13 and a second limiting block 14 are respectively disposed on the column 1. The first limiting block 13 is used to limit the horizontal position of the four-unit cylinder. When the cylinder is inserted, a screw is removed and turned outward to make room for the cylinder to enter. After it is fully inserted, it is rotated back to serve as a limiting surface. The second limiting block 14 is located in the middle of the U-shaped welded frame. The second limiting block 14 is positioned with the frame by a pin. The second limiting block 14 is a detachable structure with magnetic adhesion. The second limiting block 14 is used for positioning the guide rail during the cluster assembly process. The second limiting block 14 is removed when the cylinder is inserted or lifted out. Specifically, the limiting blocks are divided into a first limiting block 13 and a second limiting block 14. The first limiting block 13 is used to limit the horizontal position of the four-unit cylinder. There are four of them. The two bottom ones are fixed structures that can be welded or screwed. The two top ones are rotatable structures with double screws. When the cylinder is installed, one screw is removed and turned outward to make room for the cylinder to enter. After it is fully installed, it is rotated back and used as a limiting surface. The second limiting block 14 is located in the middle of the U-shaped welded frame. The connection with the frame is a pin-positioned, magnetically attached, detachable structure. It is used for positioning the guide rail during the assembly process and to ensure that the second limiting block 14 can be removed during the installation and removal of the cylinder to prevent the cylinder from being bumped.

[0052] To provide protection during transport, a rain shelter was designed, machined into a rectangular shape excluding the bottom. Tie ropes were installed at the uprights (position 1), and an opening was made in the middle of the longitudinal reinforcing tubes to facilitate hoisting without removing the tarpaulin. In this invention, the load-bearing beams, uprights (position 1), and U-shaped frame in the load-bearing structure are welded together as a whole, then machined to ensure overall rigidity and machining accuracy, reducing the possibility of subsequent deformation. The loading beam (position 3) is fastened with screws; the modular design facilitates use and maintenance.

Specifically, Step 1: Installation preparation: Unscrew the two screws of the loading beam 3 and remove the loading beam 3; unscrew the two screws in the upper part of the first limiting block 13 and rotate it to face outwards; remove the four magnetic second limiting blocks 14; Step 2: Place the cylinder: Place the cylinder on the clustering device using the hook 5 according to the front-to-back and quadrant relationship requirements of the assembly, slide it down to the bottom along the horn opening of the column 1, first place the two lower layers, then install the four magnetic second limiting blocks 14 in place, and then place the two upper layers; Step 3: Start clustering: Rotate the two upper layers of the first limiting block 13 to face inwards and tighten the screws; Push the cylinder backward so that the cylinder mating surface fits against the mating surface of the first limiting block 13; install the loading beam 3 in place and tighten the screws; use the clustering parts and standard parts to assemble the four-cylinder cluster in place, use calipers to measure each dimension, and use the measuring ruler 7 to measure the front and rear lengths along the front and rear openings to see if they meet the requirements; Step 4: Complete the assembly: Remove the loading beam 3 according to step 1, and rotate the two upper parts of the first limiting block 13 outward; push the clustered cylinder forward to facilitate the removal of the second limiting block 14; use the lifting hook 5 to lift out the four-cylinder cluster after it is assembled, and restore the device to its original state to complete the clustering assembly process.
