Description

Technical Field

[0001] This invention belongs to the field of steel structure roof truss installation technology, specifically a rapid installation auxiliary device for steel structure roof trusses. Background Technology

[0002] Typically, the roofs of some buildings are constructed using steel truss structures. A steel truss roof often consists of multiple steel truss units. When constructing a steel truss roof, these multiple steel truss units are installed on the top of the building, and they are usually arranged in a linear distribution to form the steel truss roof.

[0003] When installing this type of steel structure roof truss, it is usually divided into multiple types of trusses according to the actual site conditions, and large equipment is used to hoist the trusses. After the trusses reach the predetermined position, they are then installed and fixed together to form a steel structure roof.

[0004] In existing technology, when using large equipment to hoist trusses, it is necessary to wrap the truss surface with a rope, and then use a hoisting mechanism to hoist the fixed truss to the predetermined position. Subsequently, workers unwrap the rope at a height and fix it to the vertical beam with bolts. Since the truss is at a height, it is not only unsafe for workers to manually unwrap the rope, but also cumbersome to operate, which affects the installation of the roof truss.

[0005] Therefore, the present invention provides a rapid installation auxiliary device for steel structure roof trusses. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: The present invention provides a quick installation auxiliary device for steel structure roof trusses, comprising multiple vertical steel beams and a crane. The vertical steel beams are arranged in a linear array on the ground. A frame plate is installed on the upper surface of all the vertical steel beams. A composite truss is arranged above the frame plate. The composite truss is hoisted to the top of the frame plate by the crane. A fastening mechanism is provided at the bottom of the crane to fasten the two sides of the frame plate. The fastening mechanism includes a connecting rope installed above the crane.

[0008] Preferably, each of the composite trusses is composed of multiple square tubes in an integrated design, and each of the two ends of the composite truss is fixedly installed with a column-shaped bracket. The shape of the column-shaped bracket is adapted to the shape of the horizontal groove on the surface of the frame plate, and each column-shaped bracket and the surface of the frame plate are provided with threaded grooves.

[0009] Preferably, both ends of the connecting rope are fixedly connected to a support frame, an L-shaped support plate is installed at the bottom of the support frame, a winding rope is installed at the bottom of the L-shaped support plate, and a snap-fit ​​unit is provided on the surface of the winding rope to snap the two ends of the winding rope.

[0010] Preferably, the snap-fit ​​unit includes a mounting plate one installed at the end of the winding rope. Two through rods are installed on the surface of the mounting plate one. Each through rod has an elastic arc-shaped snap-fit ​​head installed on its upper and lower surfaces. A docking plate is installed at the bottom of the L-shaped support plate. The side surface of the docking plate is connected to one end of the winding rope. Two docking grooves are opened inside the docking plate. The shape of the two docking grooves is adapted to the shape of the through rods. Each docking groove has a snap-fit ​​groove on its groove wall.

[0011] Preferably, each of the elastic arc-shaped clips has a compression spring fitted on its outer surface, the shape of the clip groove is adapted to the shape of the elastic arc-shaped clip, and the bottom of the L-shaped support plate is provided with a release unit, which is used to release the elastic arc-shaped clip from the clip groove.

[0012] Preferably, the disengagement unit includes an electric push column installed on the lower end face of the L-shaped support plate. A horizontal plate is installed on the telescopic end of the electric push column. A pressure rod is installed on the lower end face of the horizontal plate. A vertical groove is opened on the vertical surface of the snap-fit ​​groove. The bottom of the pressure rod extends through the vertical groove. An inclined plate is installed on the upper end face of the mounting plate. A pressure rod is installed at the position corresponding to the inclined plate on the lower end face of the horizontal plate.

[0013] Preferably, the surface of the inclined plate is provided with a limiting groove, the bottom of the second pressure rod is in contact with the limiting groove, and a roller is provided at the contact position between the bottom of the second pressure rod and the limiting groove. During operation, when the second pressure rod moves down, the roller at its bottom will squeeze with the limiting groove, which can speed up the separation of the through rod from the inside of the docking groove and speed up the installation of the roof truss.

[0014] Preferably, a ball bearing is rotatably mounted at the bottom of the pressure rod, and the shape of the pressure rod matches the shape of the vertical groove.

[0015] Preferably, a spring is sleeved on the surface of the pressure rod, and one end of the spring is installed on the lower end face of the horizontal plate.

[0016] Preferably, the crane is equipped with a counterweight inside.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. The steel structure roof truss installation quick installation auxiliary device of the present invention controls the hoisting mechanism of the crane to lift the connecting rope, support frame, L-shaped support plate and winding rope, so that the composite truss is slowly lifted from the ground and placed on top of the frame plate. Since the winding rope is placed on both sides of the composite truss, the stability of the lifting is improved. This solves the problem in the prior art that the middle protrusion of the composite truss is generally hooked, which leads to self-rotation during the subsequent lifting process. The device improves the lifting speed and safety of the composite truss.

[0019] 2. The steel structure roof truss installation quick installation auxiliary device of the present invention, through the action of compression spring, elastic arc-shaped clamp and snap-fit ​​groove, can stably fix the winding rope to the surface of the composite truss, improving the safety of the composite truss during hoisting; when the composite truss is hoisted above the frame plate, the elastic arc-shaped clamp can automatically disengage from the snap-fit ​​groove under the action of the disengagement unit, eliminating the need for workers to manually untie the winding rope, solving the safety problem of untying the winding rope at high altitudes in the prior art, and facilitating the subsequent hoisting of different composite trusses, thus improving the installation speed of the roof truss.

[0020] 3. The steel structure roof truss installation quick installation auxiliary device of the present invention uses a horizontal plate to drive the second pressure rod downward. The downward movement of the second pressure rod will squeeze the inclined surface of the inclined plate. Under the pressure, the inclined plate will gradually move away from the docking plate. Then the through rod will completely disengage from the docking groove. Subsequently, the crane is controlled to lift it upward. The crane will slowly pull the winding rope out of the composite truss. This design not only eliminates the need for workers to manually untie the winding rope at a height, improving the safety of roof truss installation, but also speeds up the subsequent installation of the roof truss.

Detailed Implementation

[0032] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0033] like Figures 1 to 3 As shown in the embodiment of the present invention, a quick installation auxiliary device for steel structure roof trusses includes multiple vertical steel beams 1 and a crane 2. The vertical steel beams 1 are arranged in a linear array on the ground. A frame plate 3 is installed on the upper surface of all the vertical steel beams 1. A composite truss 4 is arranged above the frame plate 3. The composite truss 4 is hoisted to the top of the frame plate 3 by the crane 2. A fastening mechanism is provided at the bottom of the crane 2 to fasten the two sides of the frame plate 3. The fastening mechanism includes a connecting rope 6 installed above the crane 2.

[0034] During operation, the vertical steel beam 1 and the frame plate 3 are first set up at the indicated positions on the industrial park ground by welding. Then, different composite trusses 4 are placed on the ground, and each composite truss 4 is first secured by the fastening mechanism at the bottom of the crane 2 and the connecting rope 6. The crane 2 is then controlled to lift the individual composite truss 4 above the two frame plates 3, so that the two ends of the individual composite truss 4 are respectively locked into the two frame plates 3. Then, the two ends of the composite truss 4 are installed into the frame plates 3 by bolts. Afterwards, the fastening mechanism can automatically remove the connecting rope 6 from the surface of the composite truss 4 without the need for workers to manually untie the connecting rope 6. The operation is relatively safe, convenient and quick, which is conducive to the installation of the composite truss 4. The remaining composite trusses 4 are then hoisted in the same way, so that they are arranged linearly above the frame plates 3, thus allowing the roof truss to be installed quickly.

[0035] Each of the composite trusses 4 is constructed from multiple square tubes 401 in an integrated design. Each of the two ends of the composite truss 4 is fixedly installed with a column-shaped bracket 5. The shape of the column-shaped bracket 5 is adapted to the shape of the horizontal groove on the surface of the frame plate 3. Each column-shaped bracket 5 and the surface of the frame plate 3 are provided with threaded grooves.

[0036] During operation, the composite truss 4 is integrally formed by multiple square tubes 401, which improves the stability and strength of the roof truss after installation. After the crane 2 hoists the composite truss 4 above the frame plate 3, the two column-shaped brackets 5 below the composite truss 4 are placed in the horizontal grooves on the surface of the frame plate 3, so that the threaded grooves of the column-shaped brackets 5 and the frame plate 3 correspond to each other. At this time, the composite truss 4 and the frame plate 3 can be initially placed. Then, the workers use bolts to tighten and fix the threaded grooves of the column-shaped brackets 5 and the frame plate 3. The operation of the rest of the composite truss 4 is the same. Through this design, the composite truss 4 can be quickly placed by the combination of the column-shaped brackets 5 and the frame plate 3, which facilitates the subsequent installation of the roof truss.

[0037] like Figures 1 to 4 As shown, both ends of the connecting rope 6 are fixed with support frames 7. An L-shaped support plate 8 is installed at the bottom of the support frame 7. A winding rope 9 is installed at the bottom of the L-shaped support plate 8. A snap-fit ​​unit is provided on the surface of the winding rope 9. The snap-fit ​​unit is used to snap the two ends of the winding rope 9.

[0038] During operation, when the composite truss 4 is placed on the ground, the winding rope 9 above the crane 2 is passed through the inner wall of the composite truss 4, positioning it in the gap between the composite truss 4 and the square tube 401. Then, the two ends of the winding rope 9 are secured using a snap-fit ​​unit, thus fixing the winding rope 9 inside the composite truss 4. (Refer to the attached diagram.) Figure 3As shown, at this time, the two winding ropes 9 are respectively wound around the two sides of the composite truss 4. Then, the hoisting mechanism of the control crane 2 lifts the connecting rope 6, support frame 7, L-shaped support plate 8 and winding rope 9, so that the composite truss 4 is slowly lifted from the ground and placed above the frame plate 3. Since the winding ropes 9 are placed on the two sides of the composite truss 4, the stability of the lifting of the composite truss 4 is improved. This solves the problem in the prior art that the middle protrusion of the composite truss 4 is generally hooked, which leads to the easy self-rotation during the subsequent lifting process. This improves the lifting speed and safety of the composite truss 4.

[0039] like Figures 4 to 7 As shown, the snap-fit ​​unit includes a mounting plate 10 installed at the end of the winding rope 9. Two through rods 11 are installed on the surface of the mounting plate 10. Each through rod 11 has an elastic arc-shaped snap-fit ​​head 12 installed on its upper and lower surfaces. A docking plate 13 is installed at the bottom of the L-shaped support plate 8. The side surface of the docking plate 13 is connected to one end of the winding rope 9. Two docking grooves 131 are opened inside the docking plate 13. The shape of the two docking grooves 131 is adapted to the shape of the through rods 11. Each docking groove 131 has a snap-fit ​​groove 14 on its groove wall.

[0040] During operation, when the composite truss 4 is placed on the ground, the worker holds one end of the winding rope 9, passes it through the gap inside the composite truss 4, and wraps it around the surface of the composite truss 4, so that the mating plate 13 and the mounting plate 10 are aligned, as shown in the attached diagram. Figure 4 , Figure 5 and Figure 6 As shown, the workers then insert the through rod 11 on the surface of the mounting plate 10 into the two docking slots 131, causing the two elastic arc-shaped clips 12 on the surface of the through rod 11 to move along the inner wall of the docking slot 131. Subsequently, the two elastic arc-shaped clips 12 are engaged in the locking slot 14, which allows the winding rope 9 to be wound around the surface of the composite truss 4. The winding rope 9 on the other side is fixed in the same way, lifting both sides of the composite truss 4, improving its stability during hoisting, reducing the probability of it swaying, and bringing safety to the roof truss installation site.

[0041] Each of the elastic arc-shaped clips 12 has a compression spring 15 fitted on its outer surface. The shape of the clip groove 14 is adapted to the shape of the elastic arc-shaped clip 12. The bottom of the L-shaped support plate 8 is provided with a release unit, which is used to release the elastic arc-shaped clip 12 from the clip groove 14.

[0042] During operation, as the through rod 11 and the elastic arc-shaped clamp 12 move along the wall of the docking groove 131, they are compressed by the docking groove 131. The elastic arc-shaped clamp 12 and the compression spring 15 are compressed. When the elastic arc-shaped clamp 12 moves to the position corresponding to the locking groove 14, the compressed spring 15 and the elastic arc-shaped clamp 12 will recover and lock into the locking groove 14. Under the action of the compression spring 15, the elastic arc-shaped clamp 12 and the locking groove 14, the winding rope 9 can be stably fixed on the surface of the composite truss 4, improving the safety of the composite truss 4 during hoisting. When the composite truss 4 is hoisted above the frame plate 3, the elastic arc-shaped clamp 12 can be automatically detached from the locking groove 14 under the action of the detachment unit. There is no need for the staff to manually untie the winding rope 9, which solves the safety problem of untying the winding rope 9 at a high place in the prior art, and facilitates the subsequent hoisting of different composite trusses 4, improving the installation speed of the roof truss.

[0043] like Figures 4 to 9 As shown, the disengagement unit includes an electric push column 16 installed on the lower end face of the L-shaped support plate 8. A horizontal plate 17 is installed on the telescopic end of the electric push column 16. A pressure rod 171 is installed on the lower end face of the horizontal plate 17. A vertical groove 18 is opened on the vertical surface of the snap-fit ​​groove 14. The bottom of the pressure rod 171 extends into the vertical groove 18. An inclined plate 19 is installed on the upper end face of the mounting plate 10. A pressure rod 20 is installed at the position corresponding to the inclined plate 19 on the lower end face of the horizontal plate 17.

[0044] During operation, after the composite truss 4 is hoisted to the appropriate position of the frame plate 3 by the crane 2, the telescopic end of the electric push column 16 is controlled to move the horizontal plate 17 downward. The horizontal plate 17 moves the pressure rod 171 downward, causing the pressure rod 171 to move within the vertical groove 18 and press the elastic arc-shaped clamp 12 inside the clamping groove 14. This causes the elastic arc-shaped clamp 12 to be pressed and disengaged from the clamping groove 14. As the horizontal plate 17 moves downward, it simultaneously moves the pressure rod 20 downward. The pressure rod 20 presses the inclined surface of the inclined plate 19. Under the pressure, the inclined plate 19 gradually moves away from the docking plate 13. Then, the through rod 11 completely disengages from the docking groove 131. Subsequently, the crane 2 is controlled to lift the truss upward, and the crane 2 slowly pulls the winding rope 9 out of the composite truss 4. This design not only eliminates the need for workers to manually untangle the winding rope 9 at a height, improving the safety of the roof truss installation, but also speeds up the subsequent installation of the roof truss.

[0045] The inclined plate 19 has a limiting groove 191 on its surface. The bottom of the pressure rod 20 contacts the limiting groove 191. A roller is provided at the contact position between the bottom of the pressure rod 20 and the limiting groove 191. During operation, when the pressure rod 20 moves down, the roller at its bottom will squeeze against the limiting groove 191, which can speed up the separation of the through rod 11 from the inside of the docking groove 131 and speed up the installation of the roof truss.

[0046] The bottom of the pressure rod 171 is rotatably mounted with a ball bearing 172, and the shape of the pressure rod 171 is adapted to the shape of the vertical groove 18;

[0047] During operation, when the bottom of the pressure rod 171 contacts the elastic arc-shaped clamp 12, the ball bearing 172 at the bottom of the pressure rod 171 will rotate on the surface of the elastic arc-shaped clamp 12, which facilitates the elastic arc-shaped clamp 12 to disengage from the clamping groove 14, thereby making it easier for the subsequent through rod 11 to be removed from the docking plate 13, making it more convenient to use.

[0048] A spring is fitted onto the surface of the pressure rod 171, with one end of the spring installed on the lower end face of the horizontal plate 17. A counterweight is installed inside the crane 2. During operation, when the pressure rod 171 presses against the elastic arc-shaped clamp 12, the spring provides a certain amount of movement allowance for the pressure rod 171, thus facilitating the subsequent removal of the through rod 11 from the docking plate 13.

[0049] During operation, the vertical steel beams 1 and frame plates 3 are first welded to the indicated positions on the industrial park ground. Then, different composite trusses 4 are placed on the ground, and each individual composite truss 4 is secured using a fastening mechanism at the bottom of the crane 2. The crane 2 then lifts each individual composite truss 4 above two frame plates 3, securing both ends of the truss 4 into the two frame plates 3. Bolts are then used to install the two ends of the composite truss 4 into the frame plates 3. The fastening mechanism automatically removes the truss 4 from its surface without requiring manual untying of the connecting ropes, making the operation safer, more convenient, and faster, thus facilitating the installation of the composite trusses 4. The remaining composite trusses 4 are then hoisted in the same manner, arranging them linearly above the frame plates 3. The roof truss is installed quickly. The composite truss 4 is composed of multiple square tubes 401 integrated into one piece, which improves the stability and strength of the roof truss after installation. After the crane 2 lifts the composite truss 4 above the frame plate 3, the two column-shaped brackets 5 below the composite truss 4 are placed in the horizontal grooves on the surface of the frame plate 3, so that the threaded grooves of the column-shaped brackets 5 and the frame plate 3 correspond to each other. At this time, the composite truss 4 and the frame plate 3 can be initially placed. Then, the workers use bolts to tighten and fix the threaded grooves of the column-shaped brackets 5 and the frame plate 3. The operation of the other composite trusses 4 is the same. Through this design, the composite truss 4 can be placed quickly with the column-shaped brackets 5 and the frame plate 3 combined, which facilitates the subsequent installation of the roof truss.

[0050] When the composite truss 4 is placed on the ground, the winding rope 9 above the crane 2 is passed through the inner wall of the composite truss 4, so that the winding rope 9 is placed in the gap between the composite truss 4 and the square tube 401. Then, the two ends of the winding rope 9 are snapped together by the snap-fit ​​unit, that is, the winding rope 9 is fixed inside the composite truss 4. (Refer to the attached diagram.) Figure 3 As shown, at this time, the two winding ropes 9 are respectively wound around both sides of the composite truss 4. Then, the hoisting mechanism of the control crane 2 lifts the connecting rope 6, support frame 7, L-shaped support plate 8, and winding ropes 9, so that the composite truss 4 is slowly lifted from the ground and placed above the frame plate 3. Since the winding ropes 9 are placed on both sides of the composite truss 4, the stability of the lifting of the composite truss 4 is improved, which solves the problem that the existing technology generally hooks the middle protrusion of the composite truss 4, which easily leads to self-rotation during the subsequent lifting process. This improves the lifting speed and safety of the composite truss 4. When the composite truss 4 is placed on the ground, the worker holds one end of the winding rope 9 and passes it through the gap inside the composite truss 4, and wraps it around the surface of the composite truss 4, so that the docking plate 13 and the mounting plate 10 are aligned. Refer to the attached figure. Figure 4 , Figure 5 and Figure 6 As shown, the workers then insert the through rod 11 on the surface of the mounting plate 10 into the two docking slots 131, causing the two elastic arc-shaped clips 12 on the surface of the through rod 11 to move along the inner wall of the docking slot 131. Then, the two elastic arc-shaped clips 12 are engaged in the locking slot 14, which allows the winding rope 9 to be wound around the surface of the composite truss 4. The winding rope 9 on the other side is fixed in the same way, lifting both sides of the composite truss 4, improving its stability during hoisting, reducing the probability of it swaying, and bringing safety to the roof truss installation site.

[0051] As the through rod 11 and the elastic arc-shaped clamp 12 move along the wall of the docking groove 131, they are compressed by the docking groove 131. The elastic arc-shaped clamp 12 and the compression spring 15 are then compressed. When the elastic arc-shaped clamp 12 moves to the position corresponding to the locking groove 14, the compressed spring 15 and the elastic arc-shaped clamp 12 recover and lock into the locking groove 14. Under the action of the compression spring 15, the elastic arc-shaped clamp 12, and the locking groove 14, the winding rope 9 can be stably fixed to the surface of the composite truss 4, improving the safety of the composite truss 4 during hoisting. When the composite truss 4 is hoisted above the frame plate 3, the elastic arc-shaped clamp 12 can automatically detach from the locking groove 14 under the action of the detachment unit, eliminating the need for manual untying of the winding rope 9. This solves the safety problem of untying the winding rope 9 at high altitudes in existing technologies and facilitates the subsequent hoisting of different composite trusses 4, improving the safety of the roof truss. Installation speed; after the composite truss 4 is lifted by the crane 2 to the appropriate position of the frame plate 3, the telescopic end of the electric push column 16 is controlled to drive the horizontal plate 17 to move downward. The horizontal plate 17 drives the pressure rod 171 to move downward, so that the pressure rod 171 moves in the vertical groove 18 and squeezes the elastic arc-shaped clamp 12 inside the clamping groove 14, so that the elastic arc-shaped clamp 12 is compressed and disengaged from the clamping groove 14. Moreover, when the horizontal plate 17 moves downward, the horizontal plate 17 will simultaneously drive the pressure rod 20 to move downward, pressing... As the second rod 20 moves downward, it will compress the inclined surface of the inclined plate 19. Under the pressure, the inclined plate 19 will gradually move away from the docking plate 13. Then, the through rod 11 will completely detach from the docking groove 131. After that, the crane 2 will be controlled to lift it upward. The crane 2 will slowly pull the winding rope 9 out of the composite truss 4. This design not only eliminates the need for workers to manually untie the winding rope 9 at a high place, improving the safety of the roof truss installation, but also speeds up the subsequent installation of the roof truss.
