Description

Technical Field

[0001] This invention relates to the field of cross-shaped column welding technology, and more particularly to a cross-shaped column assembly system. Background Technology

[0002] This section provides only background information relevant to this disclosure and is not necessarily prior art.

[0003] With rapid economic development, low-cost and fast-construction steel structure buildings are being adopted more and more, and modern machinery is increasingly being used in the fabrication of steel structural components. The cross-shaped column is a commonly used steel structural component in large steel structure buildings and oil drilling platforms; it is constructed by welding together one H-beam and two T-beams.

[0004] Before H-beams and T-beams can be welded together, they need to be assembled. Currently, there are very few dedicated assembly equipment for cross columns in the steel structure production field. In the existing cross column assembly methods, the assembly is still completed by a combination of manual labor and cranes. Not only is the assembly accuracy not guaranteed, but it also requires a lot of manual and tedious operations, resulting in low assembly efficiency. Summary of the Invention

[0005] The purpose of this invention is to at least solve the problems of low assembly accuracy and low assembly efficiency in existing cross-post assembly methods. This objective is achieved through the following technical solution:

The number of columns is two. The support roller assembly is fixedly disposed between the two columns. The first pressing roller assembly is slidably disposed between the two columns and slides along the extension direction of the columns. The support roller assembly and the first pressing roller assembly are arranged opposite to each other. The first pressing roller assembly is used to press H-beams onto the support roller assembly.

[0007] There are two second pressing roller conveyor assemblies, which are respectively installed on the column. Both second pressing roller conveyor assemblies can move to the side where they are close to each other.

Detailed Implementation

[0054] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0055] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0056] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0057] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "over," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented as "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0058] See Figures 1-5As shown, the first aspect of the present invention provides a cross-shaped column assembly machine 2 for assembling one H-beam and two T-beams into a cross-shaped column, comprising: columns 21, a support roller assembly 23, a first pressing roller assembly 24, and a second pressing roller assembly 25. Two columns 21 are provided. The support roller assembly 23 is fixedly disposed between the two columns 21. The first pressing roller assembly 24 is slidably disposed between the two columns 21 and slides along the extension direction of the columns 21. The support roller assembly 23 and the first pressing roller assembly 24 are arranged opposite to each other, and the first pressing roller assembly 24 is used to press the H-beam onto the support roller assembly 23. Two second pressing roller assemblies 25 are provided, one-to-one corresponding to each other on the columns 21. Both second pressing roller assemblies 25 are movable towards the side where they approach each other. The two second pressing roller assemblies 25 are respectively used to press the two T-beams... The H-beam is pressed against both sides of the first pressing roller assembly 24.

[0059] According to the cross-column assembly machine of the present invention, on the one hand, the first pressing roller assembly 24 slides relative to the supporting roller assembly 23 and clamps the H-beam through the first pressing roller assembly 24 and the supporting roller assembly 23; on the other hand, the two second pressing roller assemblies 25 move towards each other, pressing the two T-beams against the two sides of the H-beam pressed by the first pressing roller assembly 24, and finally clamping the two T-beams on the H-beam and assembling them into a cross column. Compared with manual assembly, the assembly efficiency is high and the assembly accuracy is also guaranteed, which effectively solves the problems of low assembly accuracy and low assembly efficiency of the existing cross-column assembly method.

[0060] See Figure 2 , Figure 3 As shown, specifically, the first clamping roller assembly 24 and the support roller assembly 23 are arranged opposite to each other, and the first clamping roller assembly 24 slides relative to the support roller assembly 23 to clamp the H-beam; wherein, see reference Figure 8 As shown, the first pressing roller assembly 24 includes a pressing base 241, pressing bearings 242, a first pressing roller conveyor 243, and a pressing slide plate 244. Pressing slide plates 244 are installed on both sides of the pressing base 241. Pressing grooves (not shown in the figure) are formed on the opposite inner surfaces of the column 21. The pressing slide plates 244 slide in cooperation with the pressing grooves, allowing the first pressing roller assembly 24 to slide along the extension direction of the column 21. Two pressing bearings 242 are installed at the bottom of the pressing base 241. The first pressing roller conveyor 243 is located between the two pressing bearings 242 and can rotate about the axis of the pressing bearings 242. Additionally, see [reference needed]. Figure 7As shown, the support roller assembly 23 includes a first support base 231, a support bearing 232, and a support roller 233. Two support bearings 232 are installed at the top of the first support base 231, and the support roller 233 is located between the two support bearings 232. The support roller 233 can rotate about the axis of the support bearing 232.

[0061] When the first pressing roller assembly 243 and the support roller assembly 23 clamp the H-beam, the first pressing roller 243 contacts and presses against the top surface of the H-beam, and the support roller 233 contacts and supports the bottom surface of the H-beam; and the first pressing roller 243 can rotate around the axis of the pressing bearing 242, and the support roller 233 can rotate around the axis of the support bearing 232, so as to transport the clamped H-beam forward.

[0062] See Figure 3 , Figure 4 As shown, the cross column assembly machine further includes a cross beam 22 and a drive cylinder 27. The cross beam 22 is fixedly mounted on the top of the two columns 21. The drive cylinder 27 passes through the cross beam 22 and is connected to the pressing base 241. The drive cylinder 27 drives the first pressing roller assembly 24 to slide along the extension direction of the column 21.

[0063] See Figure 3 As shown, specifically, there are two second pressing roller conveyor assemblies 25. The two second pressing roller conveyor assemblies 25 move towards each other, ultimately clamping the two T-shaped steels onto the H-shaped steel and assembling them into a cross column. Each second pressing roller conveyor assembly 25 includes a mounting frame 251, a second pressing roller conveyor body 252, and a drive assembly 26. The second pressing roller conveyor body 252 is slidably connected to the mounting frame 251. The mounting frames 251 of the two second pressing roller conveyor assemblies 25 are respectively mounted on two columns 21; in other words, one mounting frame 251 is mounted on one column 21, and the other mounting frame 251 is mounted on the other column 21. The second pressing roller conveyor bodies 252 of both second pressing roller conveyor assemblies 25 can move towards the side where they are close to each other. The two second pressing roller conveyor bodies 252 are respectively used to press the two T-shaped steels against the two sides of the H-shaped steel pressed by the first pressing roller conveyor assembly 24, thereby clamping the H-shaped steel.

[0064] See Figure 5As shown, the second pressing roller conveyor body 252 further includes a second pressing roller conveyor 2521, a roller bearing 2522, a transmission drive 2523, and a guide shaft 2524. The transmission drive 2523 is mounted on the second pressing roller conveyor body 252 and is connected to the second pressing roller conveyor 2521. Both ends of the second pressing roller conveyor 2521 are rotatably connected to the roller bearing 2522. Through the driving effect of the transmission drive 2523, the second pressing roller conveyor 2521 is driven to rotate, thereby realizing the transportation of the cross-shaped workpiece. The mounting frame 251 has multiple sliding holes arranged side by side. Correspondingly, the second pressing roller conveyor body 252 has multiple guide shafts 2524 arranged side by side. When one second pressing roller conveyor body 252 is slidably connected to one mounting frame 251, the guide shaft 2524 moves in the sliding hole to achieve the effect of guiding and limiting.

[0065] See Figure 3 As shown, the drive assembly 26 further includes a commutator 261, a first drive shaft 262, and a drive motor 263. The commutator 261 and the first drive shaft 262 are connected in a transmission manner, and the first drive shaft 262 and the drive motor 263 are connected in a transmission manner. The drive motor 263 is mounted on a mounting bracket 251. In other words, one drive motor 263 is mounted on one mounting bracket 251, and the other drive motor 263 is mounted on another mounting bracket 251. The cross column assembly machine 2 also includes a crank handwheel 264 and a second drive shaft 265. The crank handwheel 264 is connected in a transmission manner to one of the commutators 261 of the two drive assemblies 26, and the commutators 261 of the two drive assemblies 26 are connected in a transmission manner through the second drive shaft 265.

[0066] See Figure 3 As shown, the operator turns the handwheel 264, which drives the commutator 261 connected to it to rotate. The commutator 261 drives the first drive shaft 262 connected to it to rotate. The first drive shaft 262 drives the drive motor 263 connected to it to move, thereby causing one of the second pressing roller bodies 252 to slide linearly along a mounting bracket 251. In addition, the two commutators 261 are connected by a second drive shaft 265, and the two commutators 265 rotate in opposite directions, thereby realizing the opposite and reciprocating movements of the two second pressing roller bodies 252. The driving process of the other second pressing roller body 252 is the same as the above driving process, and will not be described again here.

[0067] See Figure 6As shown, the drive motor 263 further includes a motor body 2631, a worm gear 2632, a turbine gear 2633, and a first lead screw 2634; the worm gear 2632 and the turbine gear 2633 are both located inside the motor body 2631; the motor body 2631 is mounted on the mounting bracket 251, the first drive shaft 262 is drivenly connected to the worm gear 2632, the worm gear 2632 is drivenly connected to the turbine gear 2633, the turbine gear 2633 is drivenly connected to one end of the first lead screw 2634, and the other end of the first lead screw 2634 is connected to the second pressing roller body 252.

[0068] When the first drive shaft 262 rotates, it simultaneously drives the worm gear 2632 of the drive motor 263 to rotate synchronously. The worm gear 2632 drives the connected turbine 2633 to rotate. The turbine 2633 is sleeved on the first lead screw 2634 and drives the first lead screw 2634 to rotate. (See also...) Figure 2 As shown, one end of the first lead screw 2634 is connected to the second pressing roller body 252 so that the rotation of the first lead screw 2634 drives the second pressing roller body 252 to slide linearly.

[0069] See Figure 1 As shown, the second aspect of the present invention provides a cross column assembly system, including a cross column assembly machine 2 as described in any of the preceding claims, and further including a transmission roller conveyor 1, a T-shaped steel pressing device 3, and a T-shaped steel support device 4.

[0070] The conveyor roller 1 is used to support and transport H-beams; the T-beam pressing device 3 is located on the conveyor roller 1 to pre-press the T-beams onto the H-beams and to transport the T-beams; the T-beam support device 4 is located on the ground to support the T-beams.

[0071] See Figure 1 , Figure 10As shown, specifically, the conveyor roller conveyor 1 is used to support and transport H-beams. The conveyor roller conveyor 1 is divided into a first conveyor roller conveyor 11 and a second conveyor roller conveyor 12. The first conveyor roller conveyor 11 includes a conveyor roller conveyor base frame 111, conveyor rollers 112, a first transmission sprocket 113, a transmission chain 114, a rotating motor 115, a support frame 116, and roller bearing seats 117. The conveyor roller conveyor base frame 111 is installed on a foundation. Multiple sets of support frames 116 are symmetrically arranged on the conveyor roller conveyor base frame 111. Each support frame 116 has a roller bearing seat 117 installed at its top. There are also multiple sets of roller bearing seats 117. The number of conveyor rollers 112 is also multiple. Both ends of the roller 112 are connected to multiple sets of roller bearing seats 117, and one transmission roller 112 rotates in a set of roller bearing seats 117. The first transmission sprocket 113 is set at one end of one transmission roller 112, and adjacent first transmission sprockets 113 are connected by transmission chains 114. The transmission motor 115 is connected to the outermost first transmission sprocket 113 by transmission chains 114 to drive the outermost first transmission sprocket 113 to rotate. Through the layer-by-layer transmission effect, all the first transmission sprockets 113 are driven to rotate, and finally all the transmission rollers 112 are rotated.

[0072] See Figure 11 As shown, the second transmission roller conveyor 12 has a structure that is roughly the same as the first transmission roller conveyor 11. The difference is that the second transmission roller conveyor 12 adds a second drive sprocket 121 to the structure of the first transmission roller conveyor 11. This is because it is necessary to install the T-shaped steel clamping device 3 on the second transmission roller conveyor 12, and the second drive sprocket 121 is directly installed on the transmission roller conveyor base frame 111 on one side. The installation height of the second drive sprocket 121 should be lower than the installation height of the first drive sprocket 113 to make room for the installation of the T-shaped steel clamping device 3. The number of second drive sprockets 121 is determined by the number of T-shaped steel clamping devices 3. For example, when there are two T-shaped steel clamping devices 3, there are four second drive sprockets 121. Two second drive sprockets 121 form a group, and the two second drive sprockets 121 are also connected by a drive chain 114. The other end of each of the two second drive sprockets 121 is connected to the first drive sprocket 113. The rotation principle of all the transmission rollers 112 on the second transmission roller conveyor 12 is the same as that of the first transmission roller conveyor 11, and will not be repeated here.

[0073] See Figure 12As shown, specifically, the T-shaped steel pressing device 3 includes a pressing base frame 31, a first moving drive assembly 32, and two first pressing roller bodies 33 disposed on the pressing base frame 31; the pressing base frame 31 is disposed on the second conveying roller 12, and the first moving drive assembly 32 drives the two first pressing roller bodies 33 to move towards each other along the extension direction of the pressing base frame 31, so as to pre-press the T-shaped steel onto the H-shaped steel and to transport the T-shaped steel.

[0074] See Figure 12 , Figure 13 As shown, the first moving drive assembly 32 further includes a drive motor 321, a second lead screw 322, a lead screw bearing 323, a lead screw bearing seat 324, and a coupling sleeve 325. There are two of each of the second lead screw 322, lead screw bearing 323, and lead screw bearing seat 324. The two lead screw bearing seats 324 are installed in the slots of the pressing base 31. The two lead screw bearings 323 are respectively installed on the two lead screw bearing seats 324, and the two second lead screws 322 pass through the two lead screw bearings 323 respectively. One end of one second lead screw 322 is connected to the drive motor 321, and the other end is connected to the coupling sleeve 325. One end of the other second lead screw 322 is connected to the coupling 325, and the other end is rotatably mounted on the side wall of the pressing base 31.

[0075] When the drive motor 321 provides rotational driving force, it drives one of the second lead screws 322 to rotate within the lead screw bearing 323. The rotating second lead screw 322 drives the other second lead screw 322 to rotate within the lead screw bearing 323 through the coupling 325, and the two second lead screws 322 rotate in opposite directions. One of the second lead screws 322 is threadedly connected to one of the first pressing roller bodies 33, and the other second lead screw 322 is threadedly connected to the other first pressing roller body 33, thereby realizing the opposite or reciprocating movement of the first pressing roller bodies 33.

[0076] See Figure 14As shown, the first pressing roller conveyor body 33 further includes a pressing roller conveyor mounting base 331, a pressing transmission roller conveyor 332, a roller conveyor bearing seat 333, a roller conveyor bearing 334, a roller conveyor sprocket 335, a roller conveyor chain 336, and a third transmission sprocket 337. One second lead screw 322 is threadedly connected to one pressing roller conveyor mounting base 331, and the other second lead screw 322 is threadedly connected to the other pressing roller conveyor mounting base 331, thereby realizing the opposite or reciprocating movement of the two first pressing roller conveyor bodies 33. Two roller conveyor bearing seats 333 are mounted on one side of the pressing roller conveyor mounting base 331. Furthermore, a roller bearing 334 is provided inside the roller bearing housing 333. Both ends of the pressing and conveying roller 332 are respectively rolledly connected to the roller bearing 334. A roller sprocket 335 is provided at one end of the pressing and conveying roller 332. A motor is installed on the opposite side of the pressing and conveying roller mounting base 331. The motor is connected to the third transmission sprocket 337. The third transmission sprocket 337 and the roller sprocket 335 are connected to each other through the roller chain 336. The motor drives the roller sprocket 335 to rotate, which in turn drives the pressing and conveying roller 332 to rotate. The two rotating pressing and conveying rollers 332 then drive the cross column forward for transport.

[0077] Combination Figure 4 , Figure 15 As shown, specifically, the cross column erecting machine 2 is also equipped with a T-shaped steel pressing assembly 28. The T-shaped steel pressing assembly 28 and the T-shaped steel support device 4 work together. The T-shaped steel pressing assembly 28 presses the top surface of the T-shaped steel, and the T-shaped steel support device 4 supports and presses the bottom surface of the T-shaped steel. Finally, the T-shaped steel is limited to the H-shaped steel by the T-shaped steel pressing assembly 28 and the T-shaped steel support device 4. The T-shaped steel pressing assembly 28 is located on the side of the cross column erecting machine 2 close to the T-shaped steel support device 4, while the second pressing roller assembly 25 is located on the side of the cross column erecting machine 2 away from the T-shaped steel support device 4.

[0078] See Figure 15 As shown, the T-shaped steel support device 4 further includes a support base 41, a lifting motor 42, a second support base 43, a second moving drive assembly 44, and two support roller bodies 45 disposed on the second support base 43; the lifting motor 42 is disposed on the support base 41, and the output shaft of the lifting motor 42 is connected to the second support base 43 to change the height of the two support roller bodies 45, thereby adapting to cross columns of different specifications; the second moving drive assembly 44 drives the two support roller bodies 45 to move towards each other or in opposite directions along the extension direction of the second support base 43 to support T-shaped steel of different specifications, and the T-shaped steel pressing assembly 28 and the T-shaped steel support device 4 together limit the T-shaped steel of different specifications on the H-shaped steel.

[0079] Combination Figure 12 , Figure 15As shown, it is worth noting that the second motion drive component 44 has the same structure and working principle as the first motion drive component 32, which will not be described again here.

[0080] See Figure 16 As shown, further, the support roller conveyor body 45 includes a support roller conveyor mounting base 451 and a support assembly 452. The support roller conveyor mounting base 451 is slidably disposed on the second support base 43, and the support assembly 452 is fixedly disposed on the support roller conveyor mounting base 451, and supports and limits T-shaped steel of different specifications through the support assembly 452; wherein, see reference Figure 17 As shown, the support assembly 452 includes a support wheel seat 4521, a baffle 4522, a support wheel shaft 4523, a bushing 4524, a support wheel 4525, and a wheel axle bearing 4526. The support wheel seat 4521 is fixedly mounted on the support roller conveyor mounting base 451. Baffles 4522 are provided at both ends of the support wheel seat 4521. The support wheel shaft 4523 passes through the baffles 4522 and the support wheel 4525. Bushings 4524 are provided on both sides of the support wheel 4525, and the support wheel shaft 4523 also passes through the bushings 4524. The wheel axle bearing 4526 is provided inside the support wheel 4525. The wheel axle bearing 4526 contacts the support wheel shaft 4523 to reduce the rotational friction between the support wheel shaft 4523 and the support wheel 4525.

[0081] Combination Figure 9 , Figure 15 As shown, it is worth noting that the T-shaped steel clamping assembly 28 and the T-shaped steel support device 4 have roughly the same structure. The difference is that the T-shaped steel clamping assembly 28 clamps the T-shaped steel from top to bottom. Therefore, the T-shaped steel clamping assembly 28 does not include the support base frame 41 inside the T-shaped steel support device 4. The other structures are exactly the same, and will not be described in detail here.

[0082] The cross-post assembly system according to the present invention has the same advantages as the cross-post assembly machine 2 of the present invention, which will not be repeated here.

[0083] Finally, the operation steps of the cross-shaped column assembly system are as follows:

[0084] (1) The control program controls all mechanisms to return to the zero position, and the worker hoists the H-beam to the corresponding position of the second transmission roller 12;

[0085] (2) See Figure 18 As shown, the worker controls the T-shaped support device 4 and the T-shaped clamping assembly 28 to move to the corresponding workpiece position;

[0086] (3) See Figure 19 As shown, the worker hoists the T-shaped part onto the T-shaped part support device 4 and places it there, and controls the T-shaped steel clamping device 3 to move to the corresponding position to clamp the cross column workpiece in the center;

[0087] (4) See Figure 20 As shown, the worker walks to the spot-fixing position, turns the handwheel 264 to move the second pressing roller assembly 25 to the corresponding cross column workpiece position, then controls the second transmission roller 12 to transmit the first spot-fixing position of the cross column workpiece to the position, and finally controls the drive cylinder 27 to work so that the first pressing roller assembly 24 and the support roller assembly 23 cooperate to press the workpiece, and then the worker spot welds the cross column workpiece to fix it.

[0088] (5) After the first spot-fixing position is completed, control the operation of the first transmission roller 11 and the second transmission roller 12 to transport the cross column workpiece forward until the second spot-fixing position is in place. Then, perform the second spot welding and fixation. Repeat the above operation until the spot welding and fixation of the workpiece is completed.

[0089] (6) Finally, the worker transports the cross column from the first conveyor roller 11 to the very end and lifts it out of the production line.

[0090] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
