Description

Technical Field

[0001] The invention belongs to the technical field of steel truss construction, and more specifically, particularly relates to a steel truss construction device. Background Art

[0002] Steel truss construction equipment is an important device to assist in the construction of steel trusses. It covers a variety of types, such as tower cranes, truck cranes and crawler cranes for lifting operations. It can lift steel truss members including U-ribs to specified heights and positions to meet the needs of different construction sites. The high-strength bolts, electric wrenches and punches in the member assembly equipment ensure that the connections between the members are tight and firm. Welding equipment such as manual arc welders and carbon dioxide gas shielded welders ensure welding quality. Measuring equipment such as total stations and levels accurately measure and control construction accuracy. There are also construction platforms to provide construction personnel with a stable operating space to facilitate various construction operations. At the same time, auxiliary materials are lifted and stored to ensure safe and orderly construction and improve the overall construction efficiency and quality of steel trusses.

[0003] However, during the implementation of the above technical solution, it was found that there were at least the following technical problems:

[0004] 1. It is extremely inconvenient to carry U-ribs manually. The special shape of the U-ribs makes it difficult to find a suitable point of force when carrying them, and it is difficult to apply force. In addition, the U-ribs may be long, making it difficult for one person to carry them completely, and it is difficult to ensure coordinated movements when multiple people work together, which can easily lead to uneven force on the U-ribs and cause them to slip or collide and be damaged. In addition, the manual handling force is limited, and the weight of the long U-ribs may exceed the human carrying capacity. Frequent stops during the handling process are inefficient, which seriously affects the construction progress and may also cause safety problems due to physical exhaustion;

[0005] 2. The U-rib is prone to tilt during transportation. External interference factors such as shaking and bumping during transportation can easily break the originally unstable force balance of the U-rib, thereby increasing the possibility of tilting, bringing greater difficulties and safety hazards to the transportation work;

[0006] 3. During the construction of steel trusses, construction workers need to climb the steel trusses with their bare hands. However, the surface of the steel trusses is smooth and there are no fulcrums. Construction workers are prone to fall due to loss of control or missing steps when climbing. Once a fall accident occurs, it is very likely to cause serious personal injury or even endanger life, which increases the risk for workers when climbing steel trusses.

[0007] In view of this, the existing structure and defects are studied and improved, and a steel truss construction equipment is provided. Summary of the invention

[0008] In order to solve the above technical problems, the present invention provides a steel truss construction equipment to solve the above problems.

[0009] A steel truss beam construction device, comprising a device main body. A ladder is connected to the side end of the device main body. A guiding long beam is arranged at the lower end of the device main body. A sliding cavity is opened at the upper end of the guiding long beam. Two driving rollers II are arranged in the sliding cavity. The driving rollers II can roll in the sliding cavity. Fixed short rods are rotatably connected to the center points of the two driving rollers II. Connecting blocks are fixedly connected to both ends of the two fixed short rods. There is a support moving platform at the upper end position of the guiding long beam. The lower ends of the support moving platform are fixedly connected to the four connecting blocks. The rolling of the two driving rollers II can drive the support moving platform to move. Two limiting long strips are fixedly connected to the upper end of the guiding long beam. Limiting chutes are opened on the opposite surfaces of the two limiting long strips. Limiting sliders are fixedly connected to both ends of the two fixed short rods. Each limiting slider is located in the corresponding limiting chute. Each limiting slider is slidably connected to the corresponding limiting long strip through the limiting chute.

[0010] Preferably, a fixing plate I is rotatably connected to the upper end of the support moving platform. A fixing bolt is rotatably connected to the upper end of the fixing plate I. Two limiting rods are fixedly connected to the lower end of the fixing plate I. The two limiting rods are parallel to each other.

[0011] Preferably, a lifting block is arranged at the lower end of the fixing plate I. The lifting block is threadedly sleeved with the fixing bolt. The lifting block is slidably connected to the corresponding limiting rod. A pressing plate is fixedly connected to the side end of the lifting block. The staff places the U-rib on the support moving platform. The staff rotates the fixing bolt. Since the lifting block is limited by the two limiting rods, the lifting block will descend along the limiting rod as the fixing bolt rotates. The pressing plate will descend along with the lifting block. At this time, the pressing plate will clamp and fix the front end of the U-rib.

[0012] Preferably, two connecting long beams are arranged at one end of the device main body. The two connecting long beams are both fixedly connected to the guiding long beam.

[0013] Preferably, L-shaped plates are fixedly connected to the upper ends of the two connecting long beams. Moving blocks I are arranged at the lower ends of the two L-shaped plates.

[0014] Preferably, rectangular grooves are opened at one ends of the two moving blocks I. Driving rollers I are arranged inside the two rectangular grooves. Connecting columns I are fixedly connected to the center points of the two driving rollers I. The upper and lower ends of the two connecting columns I are rotatably connected to the inner walls of the moving blocks I.

[0015] Preferably, fixing rings are fixedly connected to the lower ends of the two moving blocks I. Driving motors are fixedly connected to the lower ends of the fixing rings. The output ports of the two driving motors pass through the two moving blocks I and are fixedly connected to the corresponding connecting columns I. The staff starts the two driving motors simultaneously. When the two driving motors start synchronously, they will drive the corresponding driving rollers I to rotate. The synchronous rotation of the two driving rollers I will drive the U-rib on the support moving platform to move.

[0016] Preferably, moving chambers are provided at the lower ends of the two L-shaped plates. The two moving chambers are located above the upper ends of the two first moving blocks. Second moving blocks are fixedly connected to the upper ends of the two first moving blocks. The two second moving blocks are slidably connected to the corresponding L-shaped plates through the moving chambers. Threaded rods are arranged inside the two moving chambers. The two threaded rods are rotatably connected to the inner walls of the two L-shaped plates. The two second moving blocks are threadedly sleeved on the corresponding threaded rods. When the threaded rods rotate, the two second moving blocks will drive the corresponding first moving blocks to move, and the two first moving blocks will drive the corresponding first driving rollers to move, so that the two first driving rollers can always be in contact with the U-ribs.

[0017] Preferably, second connecting columns are rotatably connected to the side ends of the two L-shaped plates. The two second connecting columns are fixedly connected to the corresponding threaded rods. Driving sprockets are fixedly connected to the side ends of the two second connecting columns. Synchronous chains are meshed with the two driving sprockets. Driven sprockets are meshed with the upper ends of the two synchronous chains. The synchronous chains will drive the driving sprockets and the driven sprockets to rotate synchronously.

[0018] Preferably, a connecting long rod is arranged between the two driven sprockets. The two ends of the connecting long rod are fixedly connected to the two driven sprockets. Two fixing plates II are arranged at the two ends of the connecting long rod. Through holes are provided at the side ends of the two fixing plates II. The two ends of the connecting long rod are rotatably connected to the corresponding fixing plates II through the through holes. The lower ends of the two fixing plates II are fixedly connected to the corresponding L-shaped plates. A hexagonal knob is arranged at the side end of the connecting long rod. The hexagonal knob is fixedly connected to the connecting long rod. When the staff rotates the hexagonal knob, the connecting long rod will be driven to rotate. When the connecting long rod rotates, the corresponding driven sprocket will be driven to rotate, and the driven sprocket will drive the driving sprocket and the second connecting column to rotate through the synchronous chain. The rotation of the second connecting column will drive the threaded rod to rotate.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] In the present invention, when the staff starts the two driving motors simultaneously, when the two driving motors start synchronously, they will drive the corresponding first driving rollers to rotate. The synchronous rotation of the two first driving rollers will drive the U-ribs on the supporting moving platform to move. Starting the two driving motors to drive the first driving rollers to rotate and drive the U-ribs to move saves manpower, ensures balanced force, avoids slipping and collision, improves efficiency and ensures safety.

[0021] In the present invention, the staff places the U-rib on the supporting mobile platform and rotates the fixing bolt. Since the lifting block is limited by two limit rods, the lifting block will descend along the limit rods as the fixing bolts rotate, and the pressing plate will descend with the lifting block. At this time, the pressing plate will clamp and fix the front end of the U-rib. The U-rib is placed on the supporting mobile platform, and the fixing bolt is rotated to make the lifting block drive the pressing plate to clamp the front end of the U-rib to help stabilize it and prevent it from tilting during transportation.

[0022] In the present invention, when a staff member rotates the hexagonal knob, the connecting long rod will be driven to rotate, and when the connecting long rod rotates, the corresponding driven sprocket will be driven to rotate, and the driven sprocket will drive the driving sprocket and the connecting column 2 to rotate through the synchronous chain, and the rotation of the connecting column 2 will drive the threaded rod to rotate. When the threaded rod rotates, the two moving blocks 2 will drive the corresponding moving blocks 1 to move, and the two moving blocks 1 will drive the corresponding driving roller 1 to move, so that the two driving rollers 1 can always fit the U ribs, so that the two driving rollers 1 can adapt to U-assists of different sizes, thereby improving the adaptability of the driving rollers when fixing the U-assists.

[0023] In the present invention, when the U rib moves, the supporting mobile platform will move with the movement of the U rib. At this time, the lower end of the supporting mobile platform will drive the driving roller 2 to rotate, and the driving roller 2 will drive the fixed short rod and the limiting slider to move, and the limiting slider will only move along the limiting slide groove, thereby improving the stability of the U rib movement.

[0024] In the present invention, by setting a fixing ring, the fixing ring can effectively stabilize the installation position of the drive motor, so that the two drive motors remain stable at the moment of starting, eliminating vibration and displacement caused by starting impact, and ensuring the reliability and accuracy of the operation of the entire equipment.

[0025] In the present invention, a connecting rod is provided, and the connecting rod plays a key linkage role. The staff rotates the hexagonal knob to drive the connecting rod to rotate, which can drive the driven sprocket, the synchronous chain, the driving sprocket and the connecting column to operate in turn, and finally realize the rotation of the threaded rod, so that the moving block drives the driving roller to dynamically fit the U rib, ensuring that the U rib transportation is stable and efficient, adapting to different working conditions, and improving the overall adaptability and automation level of the equipment. The ladder provides a special climbing channel for construction personnel, and its structure is stable and has a reliable fulcrum. Construction personnel no longer need to climb the smooth and fulcrum-free steel trusses with bare hands. The staff can climb steadily by grasping the ladder crossbar and stepping on the steps, effectively avoiding the risk of falling due to missteps and stepping on empty space, greatly reducing the danger of workers when climbing steel trusses, and ensuring the safety premise of personnel working at high altitudes.

Detailed implementation manners

[0037] The following further describes in detail the implementation manners of the present invention with reference to the drawings and embodiments. The following embodiments are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

The ladder 12 provides a special climbing channel for construction workers, and its structure is stable and has a reliable fulcrum. Construction workers no longer need to climb smooth steel trusses without fulcrums by hand. Workers can climb steadily by grasping the ladder crossbar and stepping on the steps, effectively avoiding the risk of falling due to misstepping or stepping on empty space, greatly reducing the danger of workers when climbing steel trusses, and ensuring safety.

The staff places the U-rib on the supporting moving platform 13. The staff rotates the fixing bolt 24. Since the lifting block 21 is limited by the two limiting rods 22, the lifting block 21 will descend along the limiting rod 22 as the fixing bolt 24 rotates. The pressing plate 20 will descend with the lifting block 21. At this time, the pressing plate 20 will clamp and fix the front end of the U-rib.

[0077] Hexagonal knob 45: It is fixed to the side end of the connecting long rod 14. When the staff rotates it, it can drive the connecting long rod 14 to rotate. As the starting component of manual operation, it triggers a series of subsequent automatic actions to realize the precise control of the U-rib handling.

[0078] Working principle:

[0079] First step, the staff starts two driving motors 31 simultaneously. When the two driving motors 31 start synchronously, they will drive the corresponding first driving rollers 17 to rotate. When the two first driving rollers 17 rotate synchronously, they will drive the U-ribs on the supporting moving platform 13 to move. Starting the two driving motors 31 to drive the first driving rollers 17 to rotate and drive the U-ribs to move can save manpower, ensure balanced force, avoid slipping and collision, improve efficiency and ensure safety.

[0080] In the second step, the staff places the U-rib on the supporting moving platform 13. The staff rotates the fixing bolt 24. Since the lifting block 21 is limited by the two limiting rods 22, the lifting block 21 will descend along the limiting rod 22 as the fixing bolt 24 rotates, and the pressing plate 20 will descend with the lifting block 21. At this time, the pressing plate 20 will clamp and fix the front end of the U-rib. Place the U-rib on the supporting moving platform 13, rotate the fixing bolt 24 so that the lifting block 21 drives the pressing plate 20 to clamp the front end of the U-rib, helping it to be stable and preventing tilting during handling.

[0081] In the third step, when the staff rotates the hexagonal knob 45, it will drive the connecting long rod 14 to rotate. When the connecting long rod 14 rotates, it will drive the corresponding driven sprocket 43 to rotate, and the driven sprocket 43 will drive the driving sprocket 42 and the connecting column two 39 to rotate through the synchronous chain 33. The rotation of the connecting column two 39 will drive the threaded rod 41 to rotate. When the threaded rod 41 rotates, the two moving blocks two 40 will drive the corresponding moving blocks one 34 to move, and the two moving blocks one 34 will drive the corresponding driving rollers one 17 to move, so that the two driving rollers one 17 can always fit the U-rib, enabling the two driving rollers one 17 to adapt to U-ribs of different sizes, and improving the adaptability of the driving rollers one 17 when fixing the U-rib.

[0082] In the fourth step, when the U-rib moves, the supporting moving platform 13 will move along with the movement of the U-rib. At this time, the lower end of the supporting moving platform 13 will drive the driving roller two 26 to rotate, and the driving roller two 26 will drive the fixed short rod 29 and the limiting slider 25 to move, while the limiting slider 25 will only move along the limiting chute 28, improving the stability of the movement of the U-rib.

[0083] In the fifth step, by setting the fixing ring 37, the fixing ring 37 can effectively stabilize the installation position of the driving motor 31, so that when the two driving motors 31 are started instantaneously, they still remain stable, eliminating the vibration and displacement caused by the starting impact, and ensuring the reliability and accuracy of the operation of the entire equipment.

[0084] In the sixth step, by providing the connecting long rod 14, the connecting long rod 14 plays a key linkage role. When the staff rotates the hexagonal knob 45 to drive the connecting long rod 14 to rotate, it can successively drive the driven sprocket 43, the synchronous chain 33, the driving sprocket 42 and the connecting column two 39 to operate, and finally realize the rotation of the threaded rod 41, enabling the moving block one 34 to drive the driving roller one 17 to dynamically fit the U-rib, ensuring stable and efficient transportation of the U-rib, adapting to different working conditions, and improving the overall adaptability and automation level of the equipment.
