Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of auxiliary equipment for construction, and relates to a high-altitude operation operating frame, in particular to a zero-land-space high-altitude operation movable operating frame. BACKGROUND

[0002] In the process of mechanical and electrical professional pipeline installation in the construction field, the pipeline height in the corridor, garage and other areas is usually higher than 2m, and the mechanical and electrical installation workers need to work at height. At present, the commonly used climbing methods include scaffolding, ladder and mobile lifting vehicle. The scaffolding is a frame body built by steel pipes, the ladder is a metal ladder, and the mobile lifting vehicle is commonly used and can be lifted for dozens of meters.

[0003] However, in the mechanical and electrical installation engineering, the scaffolding has the characteristics of being movable, but has high requirements for the flatness and firmness of the work site. When the ground conditions are poor, the overall stability is easily affected, and the support structure needs to be adjusted repeatedly during the moving process, which is complicated to operate. Moreover, the working height and horizontal operation range are limited by the frame structure itself, and if the edge protection is not set according to the specification, the risk of falling from a high altitude will be increased. The ladder has a narrow support surface, which results in weak overall stability and high sensitivity to ground flatness. A slight tilt may cause the ladder to fall, and the working height is usually limited to a low range, with limited carrying capacity. It is only suitable for simple operation of a single person or small tools, and cannot meet the needs of large-area and multi-process mechanical and electrical installation. Although the mobile lifting vehicle can quickly realize lifting and short-distance movement, it is limited by the size of the vehicle body and the turning radius. In narrow spaces or sites with obstacles such as pipelines and equipment, the flexibility of passing and working is insufficient, and the rated load and lifting height are limited. Overloading or overheight operation will directly cause safety hazards, and it needs to rely on power sources such as electricity or fuel.

[0032] Figure 1 The structural schematic diagram of the zero-land mobile operation frame of the aerial work of the present application is shown. As Figure 1 shown, the zero-land mobile operation frame of the aerial work of the present application includes a track 4. The track 4 is installed below the roof structure beam through the fixed connecting device 5. It should be noted that although Figure 1 only one fixed connecting device 5 is shown in the figure, in actual use, the track 4 can be installed below the roof structure beam through multiple fixed connecting devices 5 as needed.

[0033] In the present application, the track 4 is made of angle steel. And, as Figure 9 and 10 shown, the track 4 includes a lateral baffle 401 and a bottom plate 402. Among them, the end of the lateral baffle 401 is provided with a vertical limiting bolt hole 403. The end of the bottom plate 402 is provided with an axial limiting hole 404.

[0035] The zero-foot-space high-altitude mobile operating frame of the present invention also includes a modular cylindrical climbing frame 1, a climbing fixing device 2, a pulley device 3, and a foot-operated lifting device 6.

[0036] The pulley device 3 is mounted on the track 4 and can move horizontally along the track 4. Figure 1 and 3 As shown, the pulley device 3 includes a connecting block 301. Two diagonal supports 302 are provided on the connecting block 301. A pulley 303 is provided at the end of each diagonal support 302. The pulley 303 is mounted on the track 4. Thus, the pulley device 3 and the track 4 form a Y-shaped structure, which can stabilize the pulley device 3 in the horizontal direction of the track 4 and prevent the pulley device 3 from swaying along the horizontal direction of the track 4.

[0037] Preferably, each of the diagonal braces 302 has two pulleys 303 at its end. The two pulleys 303 are rotatably mounted on the connecting shaft, and the end of the diagonal brace 302 is connected to the connecting shaft. Furthermore, the base plate 402 has a horizontal groove 405 through which the diagonal brace 302 passes, thereby facilitating the installation and horizontal movement of the pulleys 303 on the track 4.

[0038] In this invention, the track 4 can be made of low-alloy high-strength steel Q345, with a steel thickness of 16mm, tensile and compressive strength of 305N / mm², shear strength of 175N / mm², end-face bearing capacity of 400N / mm², yield strength of 175N / mm², and tensile strength of 470N / mm². Therefore, it can meet the load-bearing requirements. Furthermore, limiting and fixing blocks can be set on the track 4 to restrict the sliding position of the pulley 303. Additionally, liquid levels can be installed at both ends of the track 4 to determine the horizontal angle of the track 4 during installation.

[0039] The modular cylindrical climbing frame 1 is connected to the pulley device 3 via the climbing fixing device 2, and the climbing fixing device 2 is rotatable relative to the pulley device 3.

[0040] Specifically, such as Figures 2-8 As shown, the climbing and fixing device 2 includes a rotating lifting and locking tube 201, a docking bayonet tube 202, and a telescopic bayonet tube 203. The lower end of the rotating lifting and locking tube 201 is connected to the upper end of the modular cylindrical climbing frame 1, and its upper end is connected to the lower end of the docking bayonet tube 202.

[0041] The upper end of the telescopic socket pipe 203 is connected with the pulley device 3, that is, the telescopic socket pipe 203 is rotationally connected with the connecting block 301. The telescopic socket pipe 203 is provided with a swing telescopic fixing card 206, and the side wall of the telescopic socket pipe 203 is provided with a telescopic socket slot 207, so that the swing telescopic fixing card 206 can extend to the outside of the telescopic socket pipe 203 through the telescopic socket slot 207.

[0042] Preferably, the telescopic socket pipe 203 is provided with two swing telescopic fixing cards 206, and the two swing telescopic fixing cards 206 are symmetrically arranged. Moreover, the side wall of the telescopic socket pipe 203 is provided with two telescopic socket slots 207, so that the two swing telescopic fixing cards 206 can respectively extend to the outside of the telescopic socket pipe 203 through one of the telescopic socket slots 207.

[0043] The side wall of the butt socket pipe 202 is provided with a butt socket slot 208, and the swing telescopic fixing card 206 can be clamped into the butt socket slot 208.

[0044] Preferably, the side wall of the butt socket pipe 202 is provided with two butt socket slots 208, and the two swing telescopic fixing cards 206 can be respectively clamped into one of the butt socket slots 208.

[0045] Moreover, after the swing telescopic fixing card 206 is clamped into the butt socket slot 208, the upper end of the rotary jacking stop pipe 201 can abut against the inner side of the swing telescopic fixing card 206 to prevent it from moving inward, thereby achieving firm connection between the butt socket pipe 202 and the telescopic socket pipe 203.

[0046] Preferably, the telescopic socket pipe 203 is further provided with a spring fixing shaft 204. The spring fixing shaft 204 is sleeved with a spring 205, and the swing telescopic fixing card 205 is rotationally installed on the spring fixing shaft 204. Thus, under the elastic force of the spring 205, the swing telescopic fixing card 206 can be abutted outward, so that the swing telescopic fixing card 206 can extend to the outside of the telescopic socket pipe 203 through the telescopic socket slot 207.

[0047] More preferably, the upper end of the rotary jacking stop pipe 201 is provided with a first external thread 210. The lower end of the butt socket pipe 202 is provided with a first internal thread 209. The upper end of the rotary jacking stop pipe 201 and the lower end of the butt socket pipe 202 are threadedly connected together through the first external thread 210 and the first internal thread 209.

[0048] Preferably, a bolt 304 is arranged in the connecting block 301. The bolt 304 is arranged on the connecting block 301 through a nut 305 and a rubber pad 306. The bottom of the bolt 304 is connected with a steel ball accommodating disc 307, and the upper surface of the steel ball accommodating disc 307 is spaced apart from the lower surface of the top plate of the telescopic bayonet tube 203 by a certain distance. Meanwhile, the upper surface of the steel ball accommodating disc 307 and the lower surface of the top plate of the telescopic bayonet tube 203 are provided with a steel ball annular groove, and a plurality of steel balls 308 are arranged in the steel ball annular groove. Thus, the telescopic bayonet tube 203 can rotate relative to the connecting block 301.

[0049] The splicable cylindrical climbing frame 1 is provided with a plurality of fixing grooves 103 in the vertical direction. The splicable cylindrical climbing frame 1 is connected by a plurality of cylindrical climbing frames. As shown in Figure 2 the upper end of each cylindrical climbing frame is provided with a second external thread 101, and the lower end is provided with a second internal thread 102. Thus, the second external thread 101 of the lower cylindrical climbing frame is threadedly connected with the second internal thread 102 of the upper cylindrical climbing frame, and the splicable cylindrical climbing frame 1 can be connected between different cylindrical climbing frames to meet different height requirements.

[0050] Moreover, the lower end of the rotating jacking clamping tube 201 is provided with a third internal thread 211. Thus, the second external thread 101 of the uppermost cylindrical climbing frame can be threadedly connected with the third internal thread 211, so as to connect the splicable cylindrical climbing frame 1 with the rotating jacking clamping tube 201.

[0051] When installing the zero-land-space aerial work mobile operating frame of the present application, first, the top plate 501 is installed on the top plate structure beam through the expansion bolt 504, and the track 4 is installed on the fixed connecting device 5 through the vertical limiting bolt 505.

[0052] Then, the pulley 303 of the pulley device 3 is installed on the track 4.

[0053] After that, the bolt 304 is arranged through the connecting block 301, so as to rotationally connect the connecting block 301 with the telescopic bayonet tube 203.

[0054] Next, the focus is on the fixed connection of the climbing fixing device 2 itself. Specifically, as shown in Figure 4 the upper end of the rotating jacking clamping tube 201 is connected with the lower end of the butt joint bayonet tube 202 (at this time, it is necessary to connect the upper end of the rotating jacking clamping tube 201 with the lower end of the butt joint bayonet tube 202 slightly, and the upper end of the rotating jacking clamping tube 201 should not be inserted into the lower end of the butt joint bayonet tube 202 too much, so as not to affect the installation of the telescopic bayonet tube 203). Then, as shown inFigure 5 As shown, the upward movement of the docking bay tube 202, under the pushing action of the side wall of the docking bay tube 202, the swing telescopic fixed card 206 is retracted inward through the telescopic bayonet slot 207, so that the docking bay tube 202 can enter into the telescopic bayonet tube 203. Then, as shown Figure 6 As shown, after the docking bay tube 202 enters into the telescopic bayonet tube 203 and the telescopic bayonet slot 207 and the docking bayonet slot 208 are opposite, the swing telescopic fixed card 206 is extended outward through the telescopic bayonet slot 207 and the docking bayonet slot 208 under the action of the spring 205, to realize the connection between the docking bayonet tube 202 and the telescopic bayonet tube 203. Finally, as shown Figure 7 As shown, the upper end of the rotating jacking card tube 201 is further inserted into the lower end of the docking bayonet tube 202, so that the upper end of the rotating jacking card tube 201 can push the swing telescopic fixed card 206, avoiding the swing telescopic fixed card 206 from retracting inward under external force, thereby realizing the firm connection between the docking bayonet tube 202 and the telescopic bayonet tube 203.

[0055] Finally, the upper end of the uppermost cylindrical climbing frame is threadedly connected with the lower end of the rotating jacking card tube 201, that is, the installation of the zero-land mobile operation frame for high-altitude operation is completed.

[0056] The side of the foot lifting device 6 is provided with a hanging ear 604. In use, the worker's feet are fixed on the foot lifting device 6, so that the hanging ear 604 can be clamped into the fixed groove 103, so as to facilitate the worker to climb up and position on the splicable cylindrical climbing frame 1, thereby facilitating the worker to perform high-altitude installation work of the pipeline.

[0057] As shown, preferably, the foot lifting device 6 comprises a side hanging plate 601, and a foot plate 602 and a calf supporting plate 603 connected with the side hanging plate 601. The hanging ear 604 is arranged on the side hanging plate 601. The calf supporting plate 603 is provided with a calf fixed card 605. The foot plate 602 is provided with a foot palm fixed card 606. In specific use, the foot palm fixed card 606 and the calf fixed card 605 are first opened, then the feet are placed on the foot plate 602 and the calf is abutted against the calf supporting plate 603. Then, the foot palm fixed card 606 and the calf fixed card 605 are closed and locked to fix the foot lifting device 6 on the worker's feet. Then, the worker can climb up along the splicable cylindrical climbing frame 1 and position on the splicable cylindrical climbing frame 1 after climbing to the desired height by clamping the hanging ear 604 into the fixed groove 103, thereby facilitating the worker to perform high-altitude installation work of the pipeline. Figure 12 As shown, preferably, the foot lifting device 6 comprises a side hanging plate 601, and a foot plate 602 and a calf supporting plate 603 connected with the side hanging plate 601. The hanging ear 604 is arranged on the side hanging plate 601. The calf supporting plate 603 is provided with a calf fixed card 605. The foot plate 602 is provided with a foot palm fixed card 606. In specific use, the foot palm fixed card 606 and the calf fixed card 605 are first opened, then the feet are placed on the foot plate 602 and the calf is abutted against the calf supporting plate 603. Then, the foot palm fixed card 606 and the calf fixed card 605 are closed and locked to fix the foot lifting device 6 on the worker's feet. Then, the worker can climb up along the splicable cylindrical climbing frame 1 and position on the splicable cylindrical climbing frame 1 after climbing to the desired height by clamping the hanging ear 604 into the fixed groove 103, thereby facilitating the worker to perform high-altitude installation work of the pipeline.
