[0003] Currently, when using safety construction scaffolds in civil engineering, due to their large size and heavy weight, the bottom of the scaffold is often equipped with casters for easy movement. In order to ensure stability, a pressure plate is usually driven to the ground by turning a screw next to the caster to achieve fixation. However, the linkage between them is poor, the stability and reliability are not good, and the operation is cumbersome and inconvenient, which affects work efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a safe construction frame for civil engineering. By setting a fixed frame, movable wheels and support frames are respectively provided on both sides of the fixed frame. With the cooperation of structures such as fixed columns, connecting arms, toothed plates, gears and positioning components, the connecting arms can drive the movable wheels to rise off the ground, while the slider drives the support frame to fall and support it on the ground together with the fixed frame, thus ensuring the safety and stability of the construction frame. Conversely, when the support frame rises, the movable wheels can fall to contact the ground, which facilitates the movement of the device. The operation is simple, the switching is convenient, and the connection is stable and reliable, which greatly improves the work efficiency and solves the above-mentioned shortcomings in the technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a safety construction frame for civil engineering, comprising:

[0006] A support platform, wherein support columns are fixed at all four ends of the bottom of the support platform;

[0007] A fixed frame is provided at the bottom end of the support column, and the fixed frame has symmetrical fixed columns on both sides inside. The inner sides of the two fixed columns are fixed with toothed plates. The middle of the fixed frame is rotatably connected to a gear through a rotating shaft, and the two toothed plates mesh with the gear.

[0008] The bottom of the fixed frame is provided with slides on both sides. A slider is slidably connected in one slide and a connecting arm is slidably connected in the other slide. The end of the connecting arm extending outside the fixed frame is provided with a moving wheel. The end of the slider extending outside the fixed frame is provided with a support frame.

[0010] Preferably, a plug is fixed to the top of the fixed frame, a slot matching the plug is opened at the bottom of the support column, and a fixing component is provided between the plug and the slot.

[0011] Preferably, the fixing component includes first screw holes symmetrically opened on both sides of the insert block, and second screw holes facing the first screw holes are opened on both sides of the bottom end of the support column, and fastening bolts are screwed into the second screw holes.

[0012] Preferably, a protective railing is provided on the top side of the support platform, and a gate is installed at one end of the protective railing.

[0013] Preferably, the support frame is U-shaped.

[0014] Preferably, a reinforcing beam is provided between two adjacent support columns.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] By setting a fixed frame, movable wheels and support frames are respectively provided on both sides of the fixed frame. With the cooperation of structures such as fixed columns, connecting arms, toothed plates, gears and positioning components, the connecting arm can drive the movable wheels to rise off the ground, while the slider drives the support frame to fall down and support the fixed frame on the ground together, which can ensure the safety and stability of the construction frame.

Detailed Implementation

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] This utility model provides, for example Figures 1-6 The civil engineering safety construction scaffold shown includes:

[0029] Support platform 1, with support columns 4 fixed at all four ends of the bottom of support platform 1;

[0030] The fixed frame 5 is located at the bottom of the support column 4, and the fixed columns 11 are symmetrically arranged on both sides inside the fixed frame 5. The inner sides of the two fixed columns 11 are fixed with toothed plates 12. The middle of the inside of the fixed frame 5 is rotatably connected to a gear 13 through a rotating shaft, and the two toothed plates 12 mesh with the gear 13.

[0031] The bottom of the fixed frame 5 is provided with slides 6 on both sides. A slider 9 is slidably connected in one slide 6 and a connecting arm 7 is slidably connected in the other slide 6. A moving wheel 8 is provided at one end of the connecting arm 7 extending outside the fixed frame 5. A support frame 10 is provided at one end of the slider 9 extending outside the fixed frame 5. A positioning component is provided between one of the fixed posts 11 and the fixed frame 5.

[0032] The positioning assembly includes a cavity 16 formed at the top of one of the fixed posts 11. A spring 17 is fixed to one end of the cavity 16. A baffle 18 is connected to one end of the spring 17. A positioning post 15 is fixed to one end of the baffle 18 relative to the spring 17. One end of the positioning post 15 extends outside the fixed post 11. Two positioning holes 14 facing the positioning post 15 are symmetrically formed on one side of the fixed post 11.

[0033] Through the above technical solution:

[0034] When in use, when the movable wheel 8 is set on the ground, the device can be pushed and pulled to move. After moving to the construction point, by pressing the positioning post 15 on one side of the fixed frame 5, the positioning post 15 drives the baffle 18 to squeeze the spring 17. Then the positioning post 15 retracts into the cavity 16. After that, the connecting arm 7 can be pushed to move upward in the slider 9. The connecting arm 7 drives the fixed post 11 to move, so that the fixed post 11 drives the gear 13 to rotate through the toothed plate 12. Then the gear 13 drives the toothed plate 12 and the fixed post 11 on the other side to move. Thus, the fixed post 11 can drive the support frame 10 to descend through the slider 9. Then, under the rebound of the spring 17, the positioning post 15 can be reset and inserted into the positioning hole 14 above to achieve fixation. Then, the movable wheel 8 can rise and leave the ground, while the support frame 10 descends and is supported on the ground together with the fixed frame 5 to ensure the safety and stability of the construction frame.

[0035] Conversely, by pushing and pulling, the support frame 10 can be raised while the moving wheels 8 can be lowered to contact the ground, thus facilitating the movement of the device. The operation is simple, the switching is convenient, and the connection is stable and reliable, greatly improving work efficiency.

[0036] A guardrail 2 is installed on the top side of the support platform 1, and a gate 3 is installed at one end of the guardrail 2. By installing the guardrail 2, the workers working on the support platform 1 can be protected, and the gate 3 allows for easy opening and closing of the guardrail 2.

[0037] The support frame 10 is U-shaped. The U-shape provides good support.

[0038] A reinforcing beam is installed between two adjacent support columns 4. The reinforcing beam greatly enhances the stability of the construction frame.

[0039] In one specific embodiment of this utility model, a plug 19 is fixed at the top of the fixed frame 5, and a slot 20 matching the plug 19 is opened at the bottom of the support column 4. A fixing component is provided between the plug 19 and the slot 20.

[0040] The fixing component includes first screw holes 22 symmetrically opened on both sides of the insert 19, and second screw holes 23 facing the first screw holes 22 are opened on both sides of the bottom end of the support column 4. Fastening bolts 21 are screwed into the second screw holes 23.

[0041] By inserting the plug 19 into the slot 20 and screwing the fastening bolts 21 on both sides of the second screw hole 23, the fastening bolts 21 are tightened into the first screw hole 22, thereby fastening the plug 19 into the slot 20. Conversely, the plug 19 can also be pulled out of the slot 20, which facilitates the disassembly and maintenance of the fixing frame 5 and greatly improves the practicality of the device.

[0042] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
