[0025] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0026] Example 1

[0027] like Figures 1 to 3As shown, a mobile scaffold is used for side construction of a roof, which includes a base 3, a support frame 2, a mounting frame 1, a working platform 4 and a connecting assembly. The base 3 is installed on the ground of the floor, the support frame 2 is slidably connected to the base 3, and the mounting frame 1 is connected to one end of the support frame 2 through a connecting assembly. A ladder 5 is connected to the inner surface of the mounting frame 1. An operator on the support frame 2 can move to the inner bottom of the mounting frame 1 via the ladder 5. The side of the mounting frame 1 close to the inner bottom is connected to a working platform 4 parallel to the support frame 2 through a connecting assembly.

[0028] The base 3 includes two sets of guide rails 32 and rollers 33. The bottom surface of each set of guide rails 32 is connected to multiple sets of supports 31. The multiple sets of supports 31 are installed on the floor. The guide rails 32 are connected to the supports 31. The rollers 33 are slidably connected to the guide rails 32. The support frame 2 is connected to the surface of the rollers 33.

[0029] It should be noted that the roller 33 installed on the support frame 2 of the present invention can slide back and forth on the guide rail 32. The roller 33 is a non-powered design. When the support frame 2 needs to be moved, it needs to be pushed by external force, making the work safer, more convenient, safer and more reliable.

[0030] Furthermore, the support frame 2, the mounting frame 1 and the working platform 4 are in a "[" shape as a whole. By setting up a scaffold of this shape, it is convenient to carry out construction on a building with a flying eaves structure design. The construction workers can walk from one end of the support frame 2 to the scaffold and walk on the upper surface of the support frame 2. The handrail 6 serves as a protection.

[0031] In actual use, the entire scaffolding needs to be hoisted so that the roller 33 is clamped on the guide rail 32, and then a limit block is installed. The limit block is used to limit the movement of the support frame 2.

[0032] It should be further explained that the total operating load of the scaffolding does not exceed 800kg (including the weight of the construction workers). When operators go up and down the ladder 5, they must go up and down in sequence, ensuring that the next person can go up and down after the previous person has arrived safely.

[0033] When the device is parked, the roller 33 must be locked with a limit block to prevent it from sliding. When pushed by external force, the limit block must be removed to prevent it from getting stuck. The limit block is an existing device, so it will not be explained in detail.

[0034] Furthermore, handrails 6 are connected to the corresponding two side edges of the upper surface of the support frame 2 through connecting components.

[0035] It should be noted that the weight of the support frame 2 and the handrail 6 is G1 = 460 kg, the weight of the mounting frame 1 is G2 = 340 kg, the weight of the fixed platform 41 is G3 = 120 kg, and the weight of the telescopic platform 42 is G4 = 80 kg.

[0036] The guide rails 32 are provided with two groups, and the model thereof is: 20a I-beam; the I-beam is 3 meters long and weighs 84 kg.

[0037] Furthermore, the working platform 4 includes a fixed platform 41, a telescopic platform 42 and a slide rail 43. The slide rails 43 are connected to the corresponding two sides of the inner bottom surface of the fixed platform 41. The telescopic platform 42 is arranged inside the fixed platform 41 and is slidably connected to the surface of the slide rail 43.

[0038] It should be noted that the telescopic platform 42 can be pulled out or retracted for use as needed.

[0039] Furthermore, the connecting components are provided in multiple groups, and each group of connecting components includes two groups of corresponding connecting plates 7 and connecting parts, and the connecting parts pass through the two groups of connecting plates 7 to connect the mounting frame 1 and the handrail 6, the mounting frame 1 and the support frame 2, the mounting frame 1 and the working platform 4, and the handrail 6 and the support frame 2.

[0040] Furthermore, the connecting member is a bolt.

[0041] In the present invention, the bolts for connecting the mounting frame 1 and the support frame 2, the mounting frame 1 and the fixed platform 41, and the mounting frame 1 and the handrail 6 are of type M12*130, and the bolts for connecting the handrail 6 and the support frame 2 are of type M10*110.

[0042] It should be noted that the disassembly steps of the scaffolding of the present invention are opposite to its installation steps, and follow the disassembly principle of "installing components first and disassembling them later".

[0043] Example 2

[0044] This embodiment provides a mobile scaffolding. On the basis of the first embodiment, further improvements are made by changing the structure of the above-mentioned connecting parts to implement the rapid installation of the scaffolding and improve the work efficiency. For details, refer to Figures 4 to 7 The connecting part is a pin 8, which passes through two sets of corresponding connecting plates 7. The end of the pin 8 away from the insertion end of the connecting plate 7 extends to the outside of the connecting plate 7. A groove 9 is provided on the side of the end of the pin 8 away from the insertion end. The inner wall of the groove 9 is slidably connected with a card block 10. A driving component 11 is provided inside the pin 8 for driving the card block 10 to move out of the groove 9 and contact the surface of the connecting plate 7.

[0045] Furthermore, the driving assembly 11 includes a pressing plate 111, a trigger rod 112, an extrusion plate 113 and a limit assembly 12. The end face of the pin 8 close to the insertion end is provided with a mounting groove 13 connected to the groove 9. The extrusion plate 113 is slidably connected in the mounting groove 13. Pushing the extrusion plate 113 can push the block 10 out of the groove 9. The trigger rod 112 is connected to an end face of the extrusion plate 113 away from the block 10. The pressing plate 111 is connected to an end of the trigger rod 112 away from the extrusion plate 113. The limit assembly 12 is connected to the surface of the trigger rod 112 to limit the movement of the trigger rod 112.

[0046] It should be noted that the contact surface between the clamping block 10 and the extrusion plate 113 is an inclined surface.

[0047] Furthermore, the limiting assembly 12 includes a fixed ring 121, an oblique collar 122, a sliding ring 123, a retaining ring 124 and an arc-shaped insert ring 125. The fixed ring 121, the oblique collar 122 and the retaining ring 124 are fixedly sleeved on the surface of the trigger rod 112 from the side close to the extrusion plate 113. The sliding ring 123 is slidably sleeved on the surface of the trigger rod 112. The sliding ring 123 is located between the oblique collar 122 and the retaining ring 124. The mounting groove 13 A limiting groove 126 is provided on the inner wall, and the arc-shaped plug ring 125 is slidably connected in the limiting groove 126. A spring 2 127 is connected to the inner wall of the mounting groove 13, and the other end of the spring 2 127 is connected to the surface of the arc-shaped plug ring 125. A spring 128 is connected to the surface of the side of the fixing ring 121 away from the oblique ring 122. The spring 128 is sleeved on the surface of the trigger rod 112, and one end of the spring 128 is connected to the inner wall of the mounting groove 13.

[0048] It should be noted that the edge of the oblique ring 122 away from the sliding ring 123 is inclined, the outer edges of both side surfaces of the sliding ring 123 are inclined, and the inner edge of the side surface of the arc-shaped insert ring 125 close to the retaining ring 124 is inclined.

[0049] In actual use, after the latch 8 is inserted into the two sets of corresponding connecting plates 7, the pressing plate 111 is pressed. The pressing plate 111 drives the extrusion plate 113 through the trigger rod 112 to move the block 10 out of the groove 9. At the same time, the oblique ring 122 causes the arc-shaped insert ring 125 to move in the direction of the limit groove 126 until the arc-shaped insert ring 125 moves between the oblique ring 122 and the sliding ring 123. At this time, the arc-shaped insert ring 125 cooperates with the fixed plate to limit the movement of the extrusion plate 113, and the pressing plate 111 is now located in the installation groove 13. It is necessary to pull it out from the connecting plate 7. When the latch 8 is removed, the pressing plate 111 can be pressed again. As the trigger rod 112 moves, when the arc-shaped insert ring 125 causes the sliding ring 123 to abut against the surface of the retaining ring 124, the arc-shaped insert ring 125 will move toward the limit groove 126 until the arc-shaped insert ring 125 moves to the sliding ring 123 and the retaining ring 124. Due to the force of the spring 128 and the sliding ring 123, the arc-shaped insert ring 125 moves again to between the oblique ring 122 and the fixed ring 121. At this time, the latch 8 can be removed after the block 10 is moved into the groove 9.

[0050] Furthermore, a magnetic stone is connected to the interior of the extrusion plate 113 near one end of the clamping block 10 , and the clamping block 10 is made of ferromagnetic metal material.

[0051] It should be noted that the latch 8 is made of non-magnetic metal material.

[0052] In actual use, when the extrusion plate 113 moves away from the clamping block 10 , the magnetic stone will drive the clamping block 10 to move into the groove 9 .

[0053] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
