Description

Technical Field

[0001] The invention belongs to the field of construction equipment, and in particular relates to an adjustable tire frame suitable for container frames of multiple specifications and a method thereof. Background Art

[0002] As a standardized industrial product, the container's unique structural design enables it to meet the diverse needs of global trade and transportation. The external dimensions of containers are strictly standardized to ensure compatibility during stacking, loading and unloading, and transportation, while the internal dimensions vary slightly due to the box material or structural design. According to the standards of the International Organization for Standardization (ISO), the dimensions of containers vary in length and height, but are basically the same or have only minor differences in width. The frame of a container is an important part of its structure and is usually composed of a variety of steel components, including bottom side beams, bottom cross beams, upper side beams, upper cross beams, corner columns, secondary beams, etc. The container frame usually needs to be processed and manufactured on a tire frame, which is mainly used to support, position and fix the container frame components to ensure structural accuracy and stability during welding or assembly.

[0003] However, existing container frame jigs are mostly fixed structures, adapting only to a single container type. This design presents numerous drawbacks. Firstly, when processing container frames of varying sizes, jig adjustment is time-consuming and complex, often relying on manual calibration and inefficiently. Secondly, traditional mechanical clamps used to secure container frame components can easily damage component surfaces, impacting product quality. Furthermore, the positioning of secondary beams often relies on manual measurement, which is not only inefficient but also difficult to ensure accuracy, easily leading to deviations during welding or assembly.

[0004] The container frame cradle in the existing technology has obvious deficiencies in adapting to containers of multiple specifications, adjustment efficiency, component protection and positioning accuracy.

The top of one right-angled side of the limiting angle steel is fixed to the bottom of the sliding panel 9-1, and the other right-angled side is against the upper flange of the track 2, limiting the moving direction of the sliding seat 9 so that it can only move along the arrangement direction of the track 2 and will not move left or right and fall off the track. A plum blossom handle bolt is provided on the right-angled side of the limiting angle steel against the upper flange of the track 2. Tightening the plum blossom handle bolt can fix the position of the sliding seat 9. A third permanent magnetic suction cup 9-4 for magnetically adsorbing the bottom side beam of the container frame is also provided at the bottom of the sliding panel 9-1 of the sliding seat 9.

[0046] The two sets of sliding seats 9 are each equipped with an adjustable support group 8 and a fixed support group 7. The same set of support groups 8 and 7 are also provided on the same side of the tire frame panel 5. The fixed support group 7 is used to position the bottom side beams and bottom crossbeams of the container frame. The adjustable support group 8 includes a movable component that adjusts the spacing with the fixed support group 7 on the same side to accommodate container frames of different sizes. The specific structures of the adjustable support group 8 and the fixed support group 7 are as follows.

The two first backrest seats 7-2 are arranged vertically, and each first backrest seat 7-2 is fixed with a first permanent magnetic suction cup 7-1 for magnetic adsorption. Among them, the vertically arranged first backrest seat 7-2 is used to fix the bottom side beam of the container frame, and the horizontally arranged first backrest seat 7-2 is used to fix the bottom cross beam of the container frame.

[0048] like Figure 4 and Figure 5 As shown, the adjustable backrest group 8 provided in this embodiment includes a second backrest seat 8-2, a second sleeve 8-3, a sleeve movable plate 8-41, and a backrest seat movable plate 8-42. The second sleeve 8-3 is fixed to the upper surface of the tire frame panel 5 or the sliding seat 9, and is used to fix the corner column of the container frame. The sleeve movable plate 8-41 is fixed to the inner wall of the second sleeve 8-3, and a threaded hole for passing the screw rod 8-6 is provided on the bottom convex plate of the sleeve movable plate 8-41. A screw rod adjustment frame 8-7 with a certain length is provided on the tire frame panel 5 or the sliding seat 9 below the second sleeve 8-3. The bottom convex plate of the sleeve movable plate 8-41 is inserted into the screw rod adjustment frame 8-7, and the second sleeve 8-3 is controlled to move forward and backward along the opening direction of the screw rod adjustment frame 8-7 by rotating the screw rod 8-6. The second backrest 8-2 is arranged on the outside of the second sleeve 8-3. A second permanent magnetic suction cup 8-1 for magnetically adsorbing the bottom cross beam of the container frame is fixed on one side of the second backrest 8-2, and a backrest movable plate 8-42 is fixed on the other side. A movable groove 8-5 of a certain length is opened on the tire frame panel 5 or the sliding seat 9 below the second backrest 8-2, and the opening direction of the movable groove 8-5 and the screw rod adjustment frame 8-7 are perpendicular. The bottom convex plate of the backrest movable plate 8-42 is inserted into the movable groove 8-5 and forms a sliding pair with the movable groove 8-5. The position of the second backrest 8-2 is fine-tuned by pushing it. In this embodiment, the first sleeve 7-3 and the second sleeve 8-3 are both made of square steel pipes.

[0049] To enhance the stability of the container frame, several bottom secondary beams are required in addition to the bottom side beams and bottom cross beams. In the device provided in this embodiment, the positioning frame 6 serves to position the bottom secondary beams and is specifically configured as follows. A slot for positioning the positioning frame 6 is longitudinally defined in the middle of the tire frame 1. The two positioning frames 6 are arranged parallel to each other along the length of the tire frame 1. An opening is defined in the tire frame panel 5 to expose the positioning frames 6.

[0050] like Figure 7 As shown, each positioning frame 6 includes a positioning frame beam 6-1, a permanent magnetic fixer 6-2, a positioning frame base 6-3, a hydraulic device 6-4, an upper limit member 6-5, and a lower limit member 6-6. The positioning frame beam 6-1 is fixed to the upper surface of the positioning frame base 6-3, and the permanent magnetic fixers 6-2 for magnetically adsorbing the bottom secondary beam of the container frame are fixed at intervals on the positioning frame beam 6-1. The hydraulic device 6-4 is set at the bottom of the positioning frame base 6-3 and is used to control the rise or fall of the positioning frame base 6-3, thereby driving the rise or fall of the positioning frame beam 6-1. The upper limit member 6-5 for limiting the upper limit position of the positioning frame 6 and the lower limit member 6-6 for limiting the lower limit position of the positioning frame 6 are respectively set at both ends of the positioning frame base 6-3.

[0051] In this embodiment, the positioning frame base 6-3 is made of a square steel tube. The upper limit member 6-5 is made of a piece of angle steel, one right-angled side of which is welded to the lower side wall of the positioning frame base 6-3, and the other right-angled side extends away from the positioning frame base 6-3. When the positioning frame base 6-3 moves up to a certain position, the other right-angled side can abut the groove edge opened in the middle of the tire frame 1. The lower limit member 6-6 is made of two pieces of angle steel, the top of one right-angled side of each piece is welded to the bottom of the groove edge opened in the middle of the tire frame 1, and the right angles of the two pieces of angle steel are arranged relative to each other, which is the lower limit of the downward movement of the seat positioning frame base 6-3.

[0052] In the device provided in this embodiment, tire frame feet 4 for adjusting the level are respectively provided at the four corners of the bottom of the tire frame base. Figure 8 As shown, each tire frame foot 4 includes a foot support 4-1 and an adjustable foot 4-2. Foot support 4-1 is secured to the lower surface of the tire frame base by welding or bolting. Adjustable foot 4-2 is located at the bottom of foot support 4-1. The levelness of the tire frame base can be adjusted by adjusting the bolts in each adjustable foot 4-2.

[0053] Example 2

[0054] This embodiment provides a method for constructing a container frame using the adjustable tire frame provided in Example 1. The specific steps are as follows:

[0055] Step 1: Adjust the height of the tire frame foot

[0056] Rotate the adjustable foot 4-2 in the tire frame foot 4 and adjust the tire frame foot 4 at the four corners to ensure that the tire frame panel 5 is level. Ensure the accuracy of subsequent operations.

[0057] Step 2: Adjust the position of the sliding seat

[0058] According to the length of the bottom side beam of the container frame to be installed, adjust the position of the sliding seat 9 on the track 2 so that it can adapt to the length of the bottom side beam. After the adjustment is completed, tighten the plum handle bolt to fix the sliding seat 9 on the track 2.

[0059] Step 3: Fix the installation of the bottom side beam and bottom cross beam on the 7th side of the support group

[0060] Lift the bottom side beam of the container frame to the side where the fixed support assembly 7 is located, allowing it to be magnetically attached to the first longitudinal support seat 7-2 of the fixed support assembly 7 to secure the bottom side beam. Lift the bottom cross beam of the container frame to the first transverse support seat 7-2 of the fixed support assembly 7. If fine-tuning is required, push the second support seat 8-2 of the adjustable support assembly 8 to allow it to be magnetically attached to the bottom cross beam.

[0061] Step 4: Installation of corner posts

[0062] Hang the corner post of the container frame onto the first sleeve 7-3 of the fixed support assembly 7 and securely connect the corner post to the first sleeve 7-3 using a clamp. Then, hang the corner post of the container frame to the side of the adjustable support assembly 8. Rotate the screw 8-6 to move the second sleeve 8-3 back and forth along the screw adjustment frame 8-7 until the second sleeve 8-3 contacts the side corner post. Then, securely connect the corner post to the second sleeve 8-3 using a clamp.

[0063] If the first sleeve 7-3 and the second sleeve 8-3 are shorter, a square tube can be inserted on top of them to fix the first sleeve 7-3 or the second sleeve 8-3 to the square tube, and then the angle steel of the container frame is fixed to the square tube with a clamp.

[0064] Step 5: Install the bottom side beam on the side of the adjustable backrest group 8

[0065] The bottom side beam on the other side of the container frame is hoisted to the side where the adjustable backrest group 8 is set, and then the bottom side beam, bottom cross beam and corner column of the container frame are spot welded and fixed.

[0066] Step 6: Installation of bottom beam

[0067] Use hydraulic device 6-4 to raise positioning frame 6 to a preset height. Hoist the container frame's bottom secondary beam so that it magnetically attaches to permanent magnetic fixture 6-2 on positioning frame 6. Spot weld both ends of the bottom secondary beam to the bottom side beams on both sides.

[0068] Step 7: Final welding

[0069] All spot welds are fully welded to complete the bottom production of the container frame.

[0070] The embodiment described above is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Persons skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention.
