Description

Technical Field

[0001] This utility model information relates to the field of water conservancy construction, and particularly relates to a safe construction scaffold. Background Technique

[0002] The construction of water conservancy projects has many similarities with the construction of general civil engineering projects such as roads, railways, bridges, and building construction. For example: The main construction objects are mostly earthwork, stonework, concrete, metal structure, and electromechanical equipment installation projects, etc. Some construction methods are the same, some construction machinery can be shared, and some construction organization and management work can also learn from each other, etc. In water conservancy construction, construction scaffolds are widely used, and it is often necessary to use construction scaffolds to achieve building construction at different heights.

[0003] For the Chinese patent with the publication number of CN221481331U, it discloses a construction scaffold, which includes a basket device for the operator to stand and construct, and also includes four rack devices evenly installed at the four corners of the bottom of the basket device for telescopic lifting. A traveling device for rotary movement is installed at the bottom of the rack device; the rack device includes a vertical plate, a bracket is arranged in front of the vertical plate, and an electric push rod is installed on the bracket; the traveling device includes two symmetrically arranged driving rollers, a motor is arranged on one side of the driving rollers, a crawler is installed between the driving rollers, and a number of anti-slip teeth are evenly distributed on the surface of the crawler.

[0028] Such as Figures 1 - 6As shown in the figure, the utility model provides a safety construction scaffold, which includes a base 1, a lifting bracket 2 and a manned device 3. The base 1 includes a bottom plate 11, a first fixing member 12, universal wheels 13, a pull rod 15, a connecting plate 16 and an anti-slip footrest 17. There are four universal wheels 13, which are respectively fixed at the four corners of the bottom of the bottom plate 11. There are two first fixing members 12, which are fixed on both sides of one end of the bottom plate 11 and are provided with through holes. On the sides of the four corners of the base 1, a connecting plate 16 is also fixedly arranged, and an anti-slip footrest 17 is rotatably connected to the connecting plate 16. The manned device 3 includes a manned platform 31 and a second fixing member 33. The manned platform 31 is rectangular and is provided with a fence. There are two second fixing members 33, which are fixed on both sides of one end of the lower part of the manned platform 31 and are provided with through holes. The lifting bracket 2 includes a scissor-type electric lifting frame 21, pulleys 22 and a supporting device 23. The scissor-type electric lifting frame 21 is a prior art and will not be described in detail here. Two struts at one end of the lower part of the scissor-type electric lifting frame 21 are rotatably connected to the first fixing member 12. There are four pulleys 22, which are rotatably arranged on two struts at the other end of the lower part of the scissor-type electric lifting frame 21. Each connecting rod 231 is connected with two pulleys 22, and the struts connected with the pulleys 22 are rollingly arranged on the bottom plate 11. The two struts on the same side of the upper part of the scissor-type electric lifting frame 21 where the pulleys 22 are located are rotatably connected to the second fixing member 33. The supporting device 23 includes a connecting rod 231, a housing 232, a linear hydraulic cylinder 233 and a supporting plate 234. The connecting rod 231 is rotatably arranged between two struts on the other side of the upper part of the scissor-type electric lifting frame 21. There are two housings 232, which are fixedly connected to the connecting rod 231. There are two linear hydraulic cylinders 233, which are correspondingly arranged in the two housings 232. On the piston rod of the linear hydraulic cylinder 233, a supporting plate 234 is fixedly arranged. The supporting plate 234 is a circular plate, and the plane of the circular plate is parallel to the manned platform 31. The supporting plate 234 is closely attached to the bottom of the manned platform 31.

[0029] In the present utility model, the provision of the universal wheels 13 makes it easier to move the relatively heavy body. When in implementation, the anti-slip feet 17 provided on the bottom plate 11 and the support device 23 provided on the upper part of the scissor-type electric lifting frame 21 are used. The anti-slip feet 17 are opened to form an angle of 135 degrees with the side of the bottom plate 11, so that the base 1 forms the most stable support. The scissor-type electric lifting frame 21 rises, and the manned platform 31 rises accordingly. When the working environment of the present utility model is a relatively flat ground, the linear hydraulic cylinder 233 in the support device 23 is not adjusted. When the working environment of the present utility model is an inclined ground, one end of the scissor-type electric lifting frame 21 provided with the support device 23 is placed at the lower part of the inclined surface. At this time, the rising manned platform 31 is inclined, and the linear hydraulic cylinder 233 is activated to lift the inclined manned platform 31 until the manned platform 31 is in a horizontal state. The circular support plate 234 has strong stability and provides stable support for the manned platform 31. The provision of the pulleys 22 reduces the friction when the lower side struts of the scissor-type electric lifting frame 21 slide on the bottom plate 11 during rising, and improves the stability and service life of the scissor-type electric lifting frame 21. The present utility model solves the safety problems that the manned platform 31 of the existing safety construction frame is inclined and the construction frame is unstable when the working environment is a slope, and reduces the risks of the staff in the inclined surface working environment.

[0030] In a preferred safety construction frame, four first chutes 14 are provided on the upper surface of the bottom plate 11, parallel to the side of the bottom plate 11. The pulleys 22 on the scissor-type electric lifting frame 21 are correspondingly arranged in the first chutes 14. Two second chutes 178 are provided on the lower surface of the manned flat plate, parallel to the side of the manned platform 31. Second sliders 235 are provided on the upper surface of the support plate 234, and the second sliders 235 in the two support plates 234 are correspondingly arranged in the second chutes 178. When in implementation, the scissor-type electric lifting frame 21 rises, and the strut provided with the pulley 22 slides towards the strut rotatably arranged at the first fixing member 12, and the pulley 22 rolls in the same direction along the first chute 14, increasing the stability of the safety construction frame to prevent the pulley 22 from rolling off and affecting the stability of the safety construction frame. At the same time, the strut on one side of the support member provided on the upper part of the scissor-type electric lifting frame 21 also moves towards the strut rotatably arranged at the second fixing member 33, and the second slider 235 on the support plate 234 slides along the third chute 32 of the manned platform 31 to prevent the manned platform 31 from shaking left and right relative to the support plate 234, further strengthening the stability of the safety construction frame.

[0031] In a preferred safety construction scaffold, the anti-slip footrest 17 includes an arm 171, a screw 172, a lower anti-slip plate 173, an upper anti-slip plate 174, and a connecting member. The arm 171 is rotatably arranged on the connecting plate 16. At one end of the arm 171 away from the connecting plate 16, the screw 172 is arranged through a screw hole in a matching manner. A handle is vertically fixed on the upper part of the screw 172. By rotating the handle, the height of the screw 172 on the arm 171 can be adjusted. The upper anti-slip plate 174 is rectangular. At one end of the upper anti-slip plate 174, there is a screw hole matching the screw. The upper anti-slip plate 174 is hinged with the lower anti-slip plate 173. Two second chutes 178 are arranged on the lower anti-slip plate 173. The second chutes 178 are T-shaped chutes and are parallel to the side of the lower anti-slip plate 173. The connecting member is slidably arranged on the second chutes 178. The screw 172 passes through the screw hole of the upper anti-slip plate 174 and is connected to the connecting member. The screw 172 and the connecting member can be separated. At this time, by rotating the upper anti-slip plate 174, the anti-slip component can be removed. During implementation, rotate the handle on the screw 172 to adjust the screw 172 to a suitable height, then adjust the upper anti-slip plate 174 so that the upper anti-slip plate 174 reaches a suitable position and angle, and then adjust the angle between the lower anti-slip plate 173 and the upper anti-slip plate 174 through the hinge. The connecting member slides to a suitable position, and finally connect the lower part of the screw 172 to the connecting member. Through such cooperation, the anti-slip footrest 17 can achieve more stable support even on an inclined surface or some uneven complex support surfaces by adjusting the angle and height of the anti-slip component.

[0032] In a preferred safety construction scaffold, the connecting member includes a first slider 175 and a connecting column 177. The first slider 175 is a T-shaped slider and there are two, which are slidably arranged on the corresponding second chutes 178. Through holes are arranged on the upper part of the first slider 175. A threaded hole corresponding to the screw 172 is arranged in the middle of the column body of the connecting column 177. The connecting column 177 is rotatably arranged at the through holes of the two first sliders 175. The screw 172 and the connecting column 177 are connected through the screw hole. Such a setting enables the screw 172 to be perpendicular to the bottom plate 11 while evenly distributing the force to the lower anti-slip plate 173.

[0033] In a preferred safety construction scaffold, anti-slip patterns 176 are further arranged on the lower part of the lower anti-slip plate 173, increasing the friction between the anti-slip footrest 17 and the ground, so that the anti-slip footrest 17 has stronger grip in a sloping construction environment.

[0034] In a preferred safety construction scaffold, a pull rod 15 is further arranged on the bottom plate 11. A connection hole is arranged on the side of the bottom plate 11 at one end away from the first fixing member 12. The pull rod 15 is rotatably arranged at the connection hole. The pull rod 15 is arranged so that the safety construction scaffold can be directly pulled on a relatively flat road surface during transportation, and at the same time, the structure is simple and the cost is low.

[0035] The above are only the specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present utility model should be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claimed rights.
