[0036] The embodiment of the present application provides a steel ring for making a tire frame, such as Figure 1-Figure 2 and Figure 4 As shown, the steel sleeve ring tire frame includes an operating platform 10, an inner support assembly 20, an outer support assembly 30 and a top support bracket 40.

[0037] The inner support assembly 20 includes a plurality of inner support members 21 disposed on the operating platform 10, and the plurality of inner support members 21 are evenly distributed on a first virtual circumference. The outer support assembly 30 includes a plurality of outer support members 31 disposed on the operating platform 10, and the plurality of outer support members 31 are evenly distributed on a second virtual circumference, the second virtual circumference is concentric with the first virtual circumference, and the diameter of the second virtual circumference is greater than the diameter of the first virtual circumference, and a placement position for placing the steel sleeve 1 is formed between the inner support assembly 20 and the outer support assembly 30. The supporting bracket 40 includes a frame body 41 and two arc-shaped inner supporting plates 42. The frame body 41 includes two main beams 411 and an opening and closing adjustment mechanism 412. The two main beams 411 are respectively arranged on the concave sides of the two inner supporting plates 42, and one end of the two main beams 411 are hinged to each other; the opening and closing adjustment mechanism 412 is connected between the two main beams 411, and is used to adjust the opening and closing angle between the two main beams 411, and then the steel sleeve ring 1 placed in the placement position is supported by the two inner supporting plates 42 to rest against the outer supporting member 31. It can be understood that the frame body 41 is an "A"-shaped structure as a whole.

[0038] It can be understood that the inner support assembly 20 provides support for assembly, preliminary positioning and fixing of the semi-finished product rolled in blocks according to the design size of the steel sleeve 1 in the processing workshop; the outer support assembly 30 assists the inner support assembly 20 in preliminary positioning and fixing of the steel sleeve 1, and also provides a favorable support function when the support bracket 40 supports and improves the roundness of the steel sleeve 1. The support bracket 40 further extends the initially positioned steel sleeve 1 in the radial direction to make it reach the design size, and ensures the overall roundness when the steel sleeve 1 is welded as a whole.

[0039] When the steel sleeve is used to make a tire frame, first check the quality of the three semi-finished steel sleeves 1 (i.e., arc-shaped steel plates) rolled according to the design size by a professional plate rolling machine in the processing workshop. Then, place the end of one of the qualified arc-shaped steel plates in the placement position between the inner support component 20 and the outer support component 30 close to the outer support component 31, and the end of the arc-shaped steel plate is about three centimeters exposed from the outer support component 31; then splice the remaining arc-shaped steel plates in turn, and initially fix them by electric welding at the interface. Then place the top support bracket 40. After the top support bracket 40 is placed, the opening and closing angles of the two main beams 411 are increased by the opening and closing adjustment mechanism 412, and the two inner support plates 42 are used to push the steel sleeve 1 outward until each outer support component 30 is close to the steel sleeve 1; then weld the steel ring sleeve interface according to the design and specification requirements. When welding is completed and the weld is cooled, the opening and closing adjustment mechanism 412 is recovered, and finally the top support bracket 40 and the steel sleeve ring 1 are lifted stably and placed in the corresponding area to complete the production of each steel sleeve ring 1.

[0040] In the embodiment of the present application, the steel thimble manufacturing frame has a simple structure, is easy to manufacture and has low cost; when the steel thimble manufacturing frame is used to manufacture the steel thimble 1 at the construction site, the deformation of the steel thimble 1 during the splicing and welding process is reduced through the preliminary positioning of the internal support component 20 and the combined precise positioning of the external support component 30 and the top support bracket 40, thereby ensuring the roundness of the overall finished product of the steel thimble 1.

[0041] In one embodiment, if Figure 2-Figure 3 As shown, the height of the inner support member 21 is 2 / 3 of the height of the steel collar, and the height of the outer support member 31 is equal to the height of the steel collar. The inner support member 21 includes an inner support assembly 20, and the angle between the line connecting two adjacent inner support assemblies 20 and the center of the first virtual circle is 8°-9°. In order to facilitate the placement of the top support bracket 40, a chamfer is provided on the side of each inner support assembly 20 facing the center of the first virtual circle. The outer support member 31 includes an outer support assembly 30, and there are twelve outer support assemblies 30, each of which is evenly distributed on the second virtual circle in a group of two.

[0042] In a specific embodiment, the operating platform 10 can be made of a large steel plate of 15 mm thick and made of Q345 (the size is larger than the diameter of the steel collar). The inner support assembly 20 can be made of a single square steel plate of 15 mm thick and made of Q345. The inner support plate 42 of the top support bracket 40 is made of a Q345 steel plate of 15 mm thick, and a 20 cm wide steel ring is cut according to the outer edge of the inner diameter circle of the steel collar design. The main beam 411 is made of 8 cm×8 cm×0.3 cm square steel.

[0043] In one embodiment, if Figure 4 As shown, the opening and closing adjustment mechanism 412 includes a sleeve 4121 and two screw rods 4122 with opposite thread rotation directions. The inner wall of the sleeve 4121 is provided with two sections of internal threads with opposite thread rotation directions. One end of the two screw rods 4122 is respectively screwed to the two sections of internal threads on the inner wall of the sleeve 4121, and the other ends of the two screw rods 4122 are respectively hinged to the opposite inner sides of the two main beams 411. By rotating the sleeve 4121, the length of the two screw rods 4122 screwed in and out of the sleeve 4121 can be controlled at the same time, thereby increasing or decreasing the angle between the two main beams 411.

[0044] Through the above arrangement, the opening and closing adjustment mechanism 412 has a simple structure, and materials such as the screw 4122 and the sleeve 4121 with internal threads are all prefabricated and readily available, and the manufacturing process is simple.

[0045] In other embodiments, the opening and closing adjustment mechanism 412 may adopt an oil cylinder, and the cylinder body and piston rod of the oil cylinder are respectively hinged to the opposite inner sides of the two main beams 411.

[0046] In one embodiment, if Figure 4As shown, the top support bracket 40 also includes a plurality of reinforcing beams 43 , which are staggeredly arranged between the main beam 411 and the concave side of the inner support plate 42 connected to the main beam 411 .

[0047] The reinforcing beam 43 is used to transfer the load of the main beam 411 to the inner support plate 42 at multiple points. Specifically, the reinforcing beam 43 can be made of 6 cm×4 cm×0.3 cm square steel.

[0048] In one embodiment, if Figure 1 and Figure 4 As shown, a plurality of limiting hooks 44 are arranged at intervals on the outer edge of the inner support plate 42 .

[0049] The limiting hook 44 is used to assist the outer support component 30 in supporting and limiting the steel sleeve ring 1 during precise positioning and welding. Specifically, six limiting hooks 44 can be evenly distributed at an angle of 60° on the outer edge of the steel sleeve ring 1. It can be made of 20 mm thick Q345 steel plate.

[0050] In one implementation, the following method can be used to manufacture the steel sleeve ring tire frame in the embodiment of the present application:

[0051] Preparation of the inner support assembly 20: At the construction site, cut the 15 mm thick Q345 steel plate into several single square steel plates with a width (height) of 2 / 3 of the width of the steel sleeve; cut one corner of the steel plate into a chamfered shape (short right angle side: long right angle side = 1:2, long right angle side = 1 / 2 steel plate side length).

[0052] Fixing of the inner support assembly 20 on the operating platform 10: First, lay a 15mm thick Q345 steel plate (50cm larger than the diameter of the steel collar on each side) on the ground as the operating platform 10, and draw a circle (i.e., the first virtual circumference) on the operating platform 10 with the center point as the center point and the clearance radius r inside the steel collar minus 1mm as the control radius, and then divide it equally on the arc at a central angle of 8°-9°, and finally weld the cut steel plates firmly (except the bottom, the sides are not welded) on the equally divided points. The side of each steel plate after cutting and chamfering is placed above the facade, and along the radius direction toward the center of the circle.

[0053] Preparation of the external retaining assembly 30: At the construction site, a 15 mm thick Q345 steel plate is cut into 12 square steel plates with a width (height) equal to the width of the steel sleeve.

[0054] Fixing of the external support assembly on the operating platform 10: Draw a circle (i.e., the second virtual circumference) with the center point of the operating platform 10 as the center and the outer contour radius of the steel collar as the radius. On the drawn and marked circle, first locate 6 control points at a 60° center angle. On the arc marked by each control point, set two external support installation points symmetrically with a chord length of 10 cm. When installing the steel plate of the external support assembly 30, the axis of the bottom steel plate coincides with the radius of the circle. Except for the side close to the center of the circle, the other three sides of the bottom are welded and firmly fixed.

[0055] Preparation of the top support bracket 40: ① Production of the arc-shaped inner support plate 42: On the operating platform 10, draw a circle on another steel plate with the center point of the platform as the center and the clearance radius r inside the steel ring as the radius. The controlled width of the circle is 20 cm; then cut according to the marked circle, and divide the cut circle into two semi-circular rings, and finally cut off 15 cm of each of the equal semi-circular rings to provide space for the top push. ② The production of the main beam 411 of the frame 41: two square steels of equal length are used to form the skeleton. First, one end of the two skeleton square steels is cut into an arc shape, and the other end is cut into a 80cm×16mm notch along the center line of a pair of sides of the square steel. The two main beams 411 are assembled symmetrically, and the arc end is 2cm-3cm away from the inner edge of the two semi-annular inner support plates 42, and is hinged by welding steel plates and steel pins at the top; the reserved notch end is symmetrically socketed and fixed to the other end of the two semi-annular inner support plates 42, so that the two main beams 411 form a 30° angle; and the screw 4122 adjuster (i.e. Figure 4 The opening and closing adjustment mechanism 412 in the frame 41 connects the two main beams 411. The reinforcing beam 43 of the frame 41 uses several small square steels to effectively transfer the top thrust of the main beam 411 to the inner support plate 42. In the weak section at the tail end of the two annular inner support plates 42, the main beam 411 and the fixed end of the inner support plate 42 are directly connected to the tail end of the inner support plate 42 and the screw 4122 adjuster and the main beam 411 with small square steel; 30cm from the top (pointed) end of the main beam 411, a small square steel is used to connect and reinforce the inner support plate 42 at 45°. The remaining sections are also connected to the main beam 411 and the inner support plate 42 at multiple points with small square steel. ③ Limit hook 44: 20mm steel plate is cut into an "η" shape, the short side is the outer limit side, and the long side is the fixed side. Six limit hooks 44 are evenly distributed at an angle of 60° on the outer edge of the steel ring. The bottom of the long side of the limit hook 44 is aligned with the outer edge of the inner support plate 42 and welded and fixed.

[0056] The steel sleeve ring used in the embodiment of the present application has the following beneficial effects:

[0057] 1. Economic Benefits

[0058] To produce Taking the steel sleeve as an example, if the processing is completed in the workshop and the steel sleeve is transported to the construction site using extra-wide transportation, the production cost of a single steel sleeve is about 4,000 yuan; if the semi-finished product is transported to the site and one person uses the steel sleeve to make a tire frame for processing, the cost of completing a single steel sleeve is about 3,200 yuan.

[0059] In summary, completing the production of a single steel sleeve ring and using the steel sleeve ring to make the tire frame for processing at the construction site can save 600 yuan; and on-site processing can meet the project's construction progress at any time, greatly reducing the phenomenon of idle production due to material shortages; at the same time, it also reduces the cost of re-calibrating the roundness of the sleeve ring due to deformation during transportation, thereby reducing the project management cost in disguise.

[0060] 2. Social Benefits

[0061] 1. The steel sleeve tire frame uses materials commonly used on construction sites and can be adjusted according to the diameter of the steel sleeve. It can be reused, which greatly improves the utilization of material resources and reduces the carbon emissions caused by the use of steel.

[0062] 2. The steel sleeve frame can be made by one person only. The operation is simple, fast and safe. A single steel sleeve can be completed in half a day, which improves the construction efficiency while ensuring the roundness of the finished steel sleeve; greatly reducing the project cost.

[0063] 3. The application and promotion of the steel sleeve ring production frame is a beneficial supplement to the current blank of the production method of super-large diameter steel sleeve rings on site, and has high social benefits.

[0064] 3. Security

[0065] The steel sleeve ring production frame can be welded with commonly used Q345 steel plates and steel sections, which is firm and safe, easy to assemble and safe to operate. The steel sleeve ring can be processed and produced on the construction site by using this frame, which can effectively avoid the transportation safety risks of ultra-wide components in urban areas or highways. The entire operation process provides a safe operating space for the processing and production of steel sleeve rings through the joint effects of "mechanical jacking", "support" and "limiting". It not only ensures that the roundness of the steel sleeve can meet the design, but also ensures the construction safety of the operating workers.

[0066] The technical features of the above embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0067] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
