Description

Technical Field

[0001] The present invention relates to the technical field of steel structure truss devices, and particularly to a steel structure truss with high safety and strong anti-torsion performance. Background Art

[0002] A steel structure is a structure composed of steel materials and is one of the main building structure types. Its structure is mainly composed of steel beams, steel columns, steel trusses and other components made of sections and steel plates, and rust removal and anti-rust processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing are adopted. Because of its light self-weight and simple construction, it is widely used in large factories, stadiums, super high-rise buildings and other fields.

[0003] When the existing steel structure truss is installed, its joints are usually fixed by welding or a variety of screw connection methods, resulting in not only cumbersome installation work but also high work intensity.

[0004] Moreover, when the steel structure truss is used to support objects, when the supported objects are large special-shaped objects or a large number of stacked objects, it may be necessary to adjust the angle of the horizontal truss to facilitate the more stable placement or removal of the objects. For example, when the center of gravity of a large special-shaped object deviates from the middle position and is directly placed on the horizontal truss, it is easy to fall off the horizontal truss when receiving a slight collision. In order to cooperate with large special-shaped objects and adjust the angle of the horizontal truss, the large special-shaped object can be stably placed. Another example is when a large number of stacked heavy objects have a certain inclination trend on the horizontal truss. At this time, first adjust the angle of the horizontal truss, so as to reduce the risk of a large number of stacked heavy objects falling. Then, at this time, organize the large number of stacked heavy objects, so that the large number of stacked heavy objects can be stably placed. Or when a large number of stacked heavy objects are inclined and placed on the horizontal truss, adjust the angle of the horizontal truss to facilitate the stable and safe removal of the large number of stacked heavy objects.

[0005] Therefore, we design a steel structure truss with high safety and strong anti-torsion performance, which can quickly and efficiently install the horizontal truss on the vertical truss, has strong anti-torsion performance, and is convenient for safely adjusting the angle of the horizontal truss when there are heavy objects on the horizontal truss, so that large special-shaped objects or a large number of stacked objects can be stably and safely placed on the horizontal truss. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the defects existing in the prior art. The present invention provides a steel structure truss with high safety and strong anti-torsion performance, which can quickly install the horizontal truss on the vertical truss, has strong anti-torsion performance, and is convenient for safely adjusting the angle of the horizontal truss when there are heavy objects on the horizontal truss, so that large special-shaped objects or a large number of stacked objects can be stably and safely placed on the horizontal truss.

[0009] Furthermore, there are two horizontal trusses, and the two horizontal trusses are arranged in parallel. The two horizontal trusses are supported by four vertical trusses. A platform support plate is commonly installed on the tops of the two horizontal trusses, which is used to adjust the angle of the platform support plate to cooperate with manual operation when the object placed on the platform support plate is inclined, so that the object can be safely adjusted to the required angle or position, and adjusting the inclination angle of the platform support plate is convenient for safely and stably removing the object in an inclined state on the platform support plate.

[0010] Furthermore, the snap member includes a sliding sleeve, which is fixedly installed on the first fixing plate. A through hole groove is opened on the sliding sleeve. A sliding plate is slidably connected in the hole groove. A third wedge plate is fixedly installed at the bottom of the sliding plate. The sliding plate is elastically installed in the hole groove. A pressing plate is fixedly connected to the top of the sliding plate. Slide columns are fixedly connected to both sides of the bottom of the pressing plate. Four first circular grooves are evenly distributed in a circumferential manner at the top of the sliding sleeve. The two slide columns can be slidably connected to the first circular grooves in a limited manner. Among them, every time the pressing plate rotates 90 degrees, the two slide columns are sequentially adjusted and placed in adjacent first circular grooves, so that the sliding plate remains in a stable state after rotating 90 degrees; The outer wall of the first rotating column is fixedly connected with a gear, and both inclined surfaces of each tooth of the gear can cooperate with the inclined surface of the third wedge plate, so that the third wedge plate elastically retracts.

[0011] Further, a second rotating column is fixedly connected to the side of the hinge rod away from the first rotating column, and the second rotating column is rotationally connected in the first sliding plate in a limited manner.

[0012] Further, a second elastic member is fixedly connected to the inner bottom of the second limiting chute, and the first sliding plate sliding into the second limiting chute can press on the second elastic member.

[0014] Further, the adjusting mechanism includes a third sliding plate and a second sliding plate. The third sliding plate and the second sliding plate are slidably connected to the bottom of the slide rail plate in a left-right limiting manner. A second threaded rod is rotationally connected to the second sliding plate in a limited manner. The second threaded rod passes through the second circular groove on the third sliding plate. A nut is threadedly connected to the second threaded rod. A fourth sliding plate is fixedly connected to the bottom of the first sliding plate. A first limiting chute is opened at the top of the slide rail plate. The fourth sliding plate is slidably connected to the first limiting chute in a left-right limiting manner and penetrates through the first limiting chute. The fourth sliding plate is located between the third sliding plate and the second sliding plate. Adjusting the position of the third sliding plate fixes the fourth sliding plate. A first threaded rod is rotationally connected to the side of the second sliding plate away from the second threaded rod in a limited manner. The first threaded rod is threadedly connected to the threaded groove on the vertical truss. A first handle is fixedly installed on the side of the first threaded rod away from the second sliding plate.

[0015] Further, the second sliding plate is rotationally connected to the first threaded rod in a limited manner through the bearing installed thereon.

[0016] Compared with the prior art, the beneficial effects of the present invention include: The stable and safe installation of the horizontal truss and the vertical truss can be achieved only by pressing downwards. After adjusting the direction of the third wedge plate and pulling upwards, the stable and safe installation of the vertical truss and the horizontal truss can be achieved. The articulated rods, the first wedge plate, the second wedge plate, and the first sliding plate provided improve the torsional resistance function of the horizontal truss. Moreover, when the articulated rods on the horizontal truss are stored or transported, the articulated rods can be stably stored at the bottom of the horizontal truss, thus facilitating carrying and storage. The cooperation of the first wedge plate and the second wedge plate enables the horizontal truss to be centered and installed on two vertical trusses when the horizontal truss and the vertical truss are installed. When adjusting the angle of the horizontal truss subsequently, the cooperation of the first wedge plate and the second wedge plate has a certain pressing force to facilitate eliminating the torque force. When placing special-shaped large objects on the top of the horizontal truss or when multiple stacked objects are tilted, the angle of the horizontal truss can be safely adjusted, and the adjusted horizontal truss can maintain a stable state, enabling the special-shaped large objects to be stably placed or enabling the tilted stacked multiple objects to be placed at a good angle to adjust the angles of the multiple stacked objects or enabling the tilted stacked multiple objects to be removed at a safe angle.

Therefore, the following detailed implementation manners and the accompanying drawings are only exemplary descriptions of the technical solution of the present invention, and should not be regarded as all of the present invention or as a limitation or restriction on the technical solution of the present invention.

[0020] Embodiment 1: This embodiment mainly includes a vertical truss 1, a horizontal truss 2, a first fixing plate 10, a first rotating column 17, a hinged rod 19, and a first sliding plate 20.

[0021] With key reference to Figure 1 、 Figure 2 、 Figure 3 , a card slot 7 is provided in the middle of the top of the two vertical trusses 1, and the horizontal truss 2 is slidably connected in the two card slots 7.

In the middle of both vertical trusses 1, there are slide rail plates 21 fixedly connected, and on the side where the two vertical trusses 1 are close to each other, there is a slide rail plate 21 fixedly connected. The first sliding plate 20 can be horizontally slidably connected with limited positions on the slide rail plate 21, and on the vertical truss 1, there is a second limiting chute 35. When the horizontally slidable first sliding plate 20 approaches the vertical truss 1, it can slide into the second limiting chute 35.

[0023] Key reference Figure 6 , Figure 7 , Figure 8 , on each first fixed plate 10, there is a sliding sleeve 11 fixedly connected. On the top of the sliding sleeve 11, there is a through hole groove 13. In the hole groove 13, there is a sliding plate 15 slidably connected. At the bottom of the sliding plate 15, there is a third wedge plate 31 fixedly installed.

[0024] Key reference Figure 6 , on the outer wall of the middle part of the sliding plate 15, there is a first circular ring plate 28 fixedly connected. On the inner wall of the sliding sleeve 11, there is a second circular ring plate 30 rotatably connected with limited positions. The second circular ring plate 30 is placed at the bottom of the first circular ring plate 28. Between the first circular ring plate 28 and the second circular ring plate 30, there are a plurality of first elastic members 29 fixedly connected. The plurality of first elastic members 29 are evenly distributed in a circle. The number of the plurality of first elastic members 29 is preferably four.

[0025] Key reference Figure 6 , on the top of the sliding plate 15, there is a pressing plate 12 fixedly connected. On both sides of the bottom of the pressing plate 12, there are sliding columns 16 fixedly connected. On the top of the sliding sleeve 11, there are four first circular grooves 14 evenly distributed in a circle. The two sliding columns 16 can be slidably connected with limited positions in two symmetrical first circular grooves 14. Among them, every time the pressing plate 12 rotates 90 degrees, the two sliding columns 16 are sequentially adjusted and placed in the first circular grooves 14 adjacent to the original two first circular grooves 14, so that the sliding plate 15 remains stable after rotating 90 degrees.

[0026] Key reference Figure 4 and Figure 6 , it should be noted that on the outer wall of the first rotating column 17, there is a gear 18 fixedly connected. The two inclined surfaces of each tooth of the gear 18 can cooperate with the inclined surface of the third wedge plate 31, so that the third wedge plate 31 elastically retracts.

[0027] The state of the first embodiment is as follows: First, adjust the two sliding plates 15. First, lift the pressing plate 12 on the right side, rotate the pressing plate 12 so that the inclined surface of the third wedge plate 31 at the bottom of the sliding plate 15 is placed at the rightmost side, and then release the pressing plate 12. At this time, the two sliding columns 16 are placed in the two first circular grooves 14. Then lift the pressing plate 12 on the left side, rotate the pressing plate 12 so that the inclined surface of the third wedge plate 31 at the bottom of the sliding plate 15 is placed at the leftmost side, and then release the pressing plate 12. At this time, the two sliding columns 16 are placed in the two first circular grooves 14.

[0028] Then place the cross truss 2 from the card slots 7 at the tops of the two vertical trusses 1. At this time, the first sliding plates 20 are horizontally placed on the slide rail plates 21. Then press down the cross truss 2 so that the two first sliding plates 20 move horizontally to both sides. At this time, the cross truss 2 presses against the inner wall of the card slot 7, and then the two first sliding plates 20 press against the inner bottoms of the two second limiting sliding grooves 35. At this time, the pressed cross truss 2 can only move downward under the cooperation of the third wedge plate 31 and the gear 18, thus completing the installation of the cross truss 2 and the vertical truss 1, that is, only by pressing the cross truss 2, the installation of the vertical truss 1 and the cross truss 2 is completed. When disassembly is required, reverse the two third wedge plates 31, which is convenient for disassembly. When safely placing the vertical truss 1 and the cross truss 2, adjust the position of the third wedge plate 31 to rotate the hinge rod 19 to the side of the cross truss 2, and then keep the cross truss 2 in a state with relatively small occupied space. The anti-torsion of the device is enhanced by the diagonal brace of the hinge rod 19.

[0029] In the application, two cross trusses 2 are provided, and the two cross trusses 2 are arranged in parallel. The two cross trusses 2 are supported by four vertical trusses 1, and a platform support plate 37 is jointly installed on the tops of the two cross trusses 2.

[0030] Embodiment 2: On the basis of Embodiment 1, a technical means is added to make the cross truss 2 be installed relatively centered on the vertical truss 1.

[0031] Focus on referring to Figure 2 , first wedge plates 3 are fixedly connected to both sides of the cross truss 2, L-shaped plates 5 are fixedly connected to the mutually remote sides of the two vertical trusses 1, second wedge plates 4 are connected to the L-shaped plates 5 in a left-right limiting sliding manner, elastic telescopic members 6 are fixedly connected between the second wedge plates 4 and the vertical trusses 1, and the two first wedge plates 3 cooperate with the two second wedge plates 4 respectively to make the cross truss 2 be centered and placed on the vertical truss 1. The second wedge plates 4 are connected to the horizontal plates of the L-shaped plates 5 in a left-right limiting sliding manner, and the vertical plates of the L-shaped plates 5 are limiting plates to limit the movement of the second wedge plates 4.

[0032] In Embodiment 2, when pressing the cross truss 2, the first wedge plates 3 and the second wedge plates 4 cooperate. Under the action of the elastic telescopic members 6 on both sides, the cross truss 2 has a tendency to move towards the middle, and gently hold the cross truss 2 to make the cross truss 2 automatically centered and placed.

[0033] In the application, the platform support plate 37 is stably placed at the required position.

[0034] Other structures are the same as those in the first embodiment.

[0035] Embodiment 3: On the basis of Embodiment 2, technical means are added to facilitate the adjustment of the angle of the horizontal truss 2, so that the stacked objects or other special-shaped large objects on the top of the platform support plate 37 can be safely adjusted to the required angle and position, and it is convenient to safely and stably unload the stacked objects or other special-shaped large objects in an inclined state on the platform support plate 37.

[0036] Focus on referring to Figure 10 , a second elastic member 36 is fixedly connected to the inner bottom of the second limiting sliding groove 35, and the first sliding plate 20 sliding into the second limiting sliding groove 35 presses on the second elastic member 36.

[0037] Focus on referring to Figure 5 and Figure 9 , the bottom of the slide rail plate 21 is horizontally and limit slidably connected with a third sliding plate 26 and a second sliding plate 23. The second sliding plate 23 is rotatably connected with a second threaded rod 25 in a limited manner. The second threaded rod 25 horizontally penetrates through a second circular groove 34 on the third sliding plate 26. A nut 27 is threadedly connected to the second threaded rod 25. The bottom of the first sliding plate 20 is fixedly connected with a fourth sliding plate 24. A first limiting sliding groove 22 is formed in the top of the slide rail plate 21. The fourth sliding plate 24 is horizontally and limit slidably connected in the first limiting sliding groove 22 and penetrates through the first limiting sliding groove 22. The fourth sliding plate 24 is located between the third sliding plate 26 and the second sliding plate 23. The position of the third sliding plate 26 is adjusted to fix the fourth sliding plate 24 through the nut 27.

[0038] Focus on referring to Figure 9 , one side of the second sliding plate 23 away from the second threaded rod 25 is rotatably connected with a first threaded rod 9 in a limited manner through a bearing 33 installed thereon. The first threaded rod 9 is threadedly connected to a threaded groove 32 on the vertical truss 1. One side of the first threaded rod 9 away from the second sliding plate 23 is fixedly installed with a first threaded rod 9.

[0039] In this embodiment, after the horizontal truss 2 is adjusted to the required position, it is found that the object on the top of the horizontal truss 2 has a certain tendency to tilt. When there is a certain risk that the object is placed on the horizontal truss 2 for a long time, pull up each pressing plate 12 at this time, and change the direction of the sliding plate 15 to rotate the pressing plate 12 by 180 degrees so that the inclined surface of the third wedge plate 31 is on the other side. At this time, move the third sliding plate 26 so that the third sliding plate 26 and the second sliding plate 23 fix the fourth sliding plate 24. At the same time, rotate the wheels 8 on both sides to lift the horizontal truss 2. At this time, the gravity of the horizontal truss 2 presses on the second wedge plate 4 through the first wedge plate 3, and the horizontal truss 2 can be stably placed through the inner walls of the slide rail plate 21 and the second limit chute 35, and has a certain anti-torsion effect.

[0040] Then, according to the tilting direction of the object on the horizontal truss 2, adjust the tilting angle of the horizontal truss 2 so that the object remains stable, so as to facilitate the stable placement or stable and safe unloading of the object by personnel. The specific adjustment method is in the following embodiment of this example.

[0041] Other structures are the same as those in the second embodiment.

[0042] In the application, first raise the height of the platform support plate 37, and then adjust the angle of the horizontal truss 2 so that the stacked objects or other special-shaped large objects can be stored or unloaded stably and safely.

[0043] In this embodiment, first adjust the direction of the pressing plate 12 so that the third wedge plate 31 cooperates with the gear 18, that is, the horizontal truss 2 can move downward stably. At this time, the fourth sliding plate 24 first penetrates the first limit chute 22 on the slide rail plate 21. And under the cooperation of the first wedge plate 3 and the second wedge plate 4, the horizontal truss 2 moves downward in the middle. At this time, the horizontal truss 2 presses on the inner bottom of the card slot 7, and the first sliding plate 20 is also stuck in the slide rail plate 21 and the second limit chute 35. At this time, the horizontal truss 2 is stuck and cannot move upward. That is, the installation of the vertical truss 1 and the horizontal truss 2 is completed by directly moving the horizontal truss 2 downward. When disassembling, rotate the pressing plate 12 by 180 degrees so that the inclined surface of the third wedge plate 31 cooperates with the other surface of another tooth of the gear 18. At this time, pulling up the horizontal truss 2 can realize the disassembly of the horizontal truss 2 and the vertical truss 1.

[0044] When the objects above the cross truss 2 need to be stored at a good posture angle or when the objects stacked above the cross truss 2 have a certain tilting tendency, each pressing plate 12 is pulled upward and rotated 180 degrees, and the inclined surface of the third wedge plate 31 is matched with the other side of another tooth of the gear 18. At this time, the rotating wheel 8 is rotated to make the cross truss 2 rise to a certain height. Since the third sliding plate 26 and the second sliding plate 23 fix the first sliding plate 20 and the fourth sliding plate 24, the cross truss 2 will not fall. It should be noted that in the first and second embodiments, the third sliding plate 26 and the second sliding plate 23 do not fix the first sliding plate 20 and the fourth sliding plate 24. When the right side of the transverse truss 2 needs to be tilted, the inclined surface of the third wedge plate 31 on the right side is placed at the far left, so that the inclined surface of the third wedge plate 31 on the left side is placed at the far left. At this time, the right wheel 8 is rotated to tilt the right side of the transverse truss 2. At this time, the hinge rod 19, gear 18, and first rotating column 17 on the left side remain stationary, and the first fixed plate 10, sliding sleeve 11, and transverse truss 2 rotate around the first rotating column 17. At this time, the transverse truss 2 can be adjusted to a variety of angles. If the left side of the transverse truss 2 needs to be tilted, the inclination angle of the transverse truss 2 is adjusted in the same way as the above principle. At this time, the cooperation of the first wedge plate 3 and the second wedge plate 4 allows the pressure on the transverse truss 2 to be shared, thereby improving the anti-torque effect.

[0045] At this time, the large irregular objects or stacked objects placed on the transverse truss 2 can be stably and safely placed or stably and safely removed. After adjusting the angle of the rear transverse truss 2, the pressing plate 12 is rotated 90 degrees to completely lock the third wedge plate 31 with the gear 18. At this time, the gear 18 and the third wedge plate 31 remain relatively still and will not move. Thus, the device remains stable.

[0046] The technical scope of the present invention is not limited to the contents in the above description. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of ​​the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
