Description

Technical Field

[0001] This application relates to the field of construction technology, and particularly to a fall-prevention scaffolding for construction. Background Art

[0002] Scaffolding is one of the essential equipment in the construction process, and is widely used in the construction of buildings, bridges, tunnels and other projects. Its main function is to provide a platform for workers to work at heights, and is also used for stacking construction materials and tools. During the high-altitude operation process, the safety of workers is always the primary consideration. Therefore, the research and application of fall-prevention scaffolding are particularly important;

[0003] Although the existing fall-prevention scaffolding can prevent workers from falling to a certain extent and ensure the safety of workers, most of the scaffolding is usually of a fixed structure and cannot flexibly adjust the construction space according to specific construction tasks and site conditions, which may lead to difficulties in carrying out some complex construction operations, affecting the construction efficiency and quality. When adjusting the construction position, the whole device needs to be moved, and the operation is very inconvenient. Therefore, we urgently need to provide a fall-prevention scaffolding for construction.

[0004] The above information disclosed in this background art is only used to increase the understanding of the background art of this application. Therefore, it may include prior art that is not known to those of ordinary skill in the art. Utility Model Content

[0007] A fall-prevention scaffolding for construction includes a main frame body. A construction frame is fixedly installed at the upper end of the main frame body. A plurality of sliding seats are fixedly installed at both ends of the bottom of the construction frame. Two extension frames are respectively slidably connected inside the plurality of sliding seats. The two extension frames are arranged on the left and right sides of the construction frame. Installation seats are fixedly installed at both the front and rear ends of the construction frame. An electric cylinder is installed inside the installation seat. The output end of the electric cylinder penetrates through the installation seat and is connected with a concave seat. Two connecting rods are movably connected inside the concave seat. Connecting blocks are provided at the other ends of the two connecting rods. The two connecting blocks are respectively fixedly connected to the inner ends of the bottom of the extension frames. The two groups of connecting rods are arranged in a rhombus shape at the bottom of the construction frame. Expansion rods are fixedly installed on both sides of the upper end of the extension frames. The other ends of the expansion rods are fixedly installed at the upper end of the construction frame.

[0008] Preferably, self-locking universal wheels are fixedly installed at the four corners of the bottom of the main frame body, and a ladder is fixedly installed at one end on the left side of the construction frame.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The following will further describe the present application in detail Figures 1-4 with reference to the attached

[0020] An embodiment of the present application discloses an anti-falling scaffolding for construction. Refer to Figures 1-4 , which includes a main frame body 1. A construction frame 3 is fixedly installed at the upper end of the main frame body 1. A plurality of sliding seats 5 are fixedly installed at both ends of the bottom of the construction frame 3. Two extension frames 6 are respectively slidably connected to the inner sides of the plurality of sliding seats 5. Through the cooperation between the bottom of the extension frame 6 and the inner side of the sliding seat 5, the stability during the horizontal movement on both sides of the construction frame 3 is enhanced. The two extension frames 6 are arranged on the left and right sides of the construction frame 3. Installation seats 7 are fixedly installed at both the front and rear ends of the construction frame 3. An electric cylinder 8 is installed inside the installation seat 7. The output end of the electric cylinder 8 penetrates through the installation seat 7 and is connected to a concave seat 9. By setting two electric cylinders 8, the two concave seats 9 at the bottom of the construction frame 3 can be driven to move towards each other. Two connecting rods 10 are movably connected inside the concave seat 9. Connection blocks 11 are provided at the other ends of the two connecting rods 10. The two connection blocks 11 are respectively fixedly connected to one end of the inner side of the bottom of the extension frame 6. The two groups of connecting rods 10 are arranged in a rhombus shape at the bottom of the construction frame 3. When the two concave seats 9 move synchronously towards the inside, it will drive the deformation of the rhombic connecting rod 10 structure inside it, so that the other ends of the two groups of connecting rods 10 cooperate with the connection blocks 11 to push the extension frame 6 out from the inner side of the sliding seat 5 towards both ends of the construction frame 3, thereby expanding the operation space at the upper end of the construction frame 3, enhancing the applicability of the device, avoiding the cumbersome problem of adjusting the construction position back and forth, ensuring the construction efficiency. Telescopic rods 12 are fixedly installed on both sides of the upper end of the extension frame 6. The other ends of the telescopic rods 12 are fixedly installed at the upper end of the construction frame 3. By stretching or contracting the telescopic rods 12 following the movement of the extension frame 6, the stability of the extension frame 6 is improved, and at the same time, the upper end of the extension frame 6 is protected.

[0021] Refer to Figures 1-2 , self-locking universal wheels 2 are fixedly installed at the four corners of the bottom of the main frame body 1. A ladder 4 is fixedly installed at one end of the left side of the construction frame 3. Two fixing blocks 13 are fixedly installed at the four corners of the main frame body 1. Connection holes 14 are opened on the surfaces of the fixing blocks 13. Two support arms 15 are provided at the four corners of the main frame body 1. One ends of the support arms 15 close to the fixing blocks 13 are fixedly connected with rotating rods 16. The rotating rods 16 are arranged inside the connection holes 14. The two support arms 15 are respectively connected inside the connection holes 14 of the two fixing blocks 13 through the rotating rods 16, so as to conveniently adjust the angles of the support arms 15 at the four corners of the main frame body 1 and be applicable to the auxiliary support and fixation at positions in different environments. One ends of the support arms 15 far from the fixing blocks 13 are fixedly connected with fixing plates 17. An adjusting screw 18 is threadedly connected inside the fixing plate 17. An anti-slip pad 19 is fixedly connected to the bottom of the adjusting screw 18. By respectively rotating the adjusting screw 18, the anti-slip pad 19 at its bottom moves downward and acts on the ground at the construction position, increasing the contact area between the main frame body 1 and the ground, thereby improving the stability of the entire device and ensuring that construction workers will not easily fall due to the shaking of the construction frame 3.

[0022] The implementation principle of the anti-falling scaffolding for construction in the embodiments of this application is as follows: During specific use, first, the entire device is moved to the designated construction location by using multiple sets of self-locking universal wheels 2. Subsequently, the support arms 15 at the four corners of the main frame 1 are rotated to appropriate angles respectively, and then the adjusting screw 18 is rotated to move downward, so that the anti-slip pad 19 acts on the ground. Then, the operator climbs onto the construction frame 3 with the help of the escalator 4 to perform construction operations. When it is necessary to expand the construction space, two electric cylinders 8 are started to drive the two concave seats 9 to push inward simultaneously, causing the rhombus-shaped connecting rod 10 structure to deform. As a result, the two ends of the connecting rod 10 push the two extension frames 6 outward through the connecting blocks 11, enabling the staff to stand on the upper end of the extension frames 6 to perform construction operations.
