Description

Technical Field

[0001] This invention relates to the field of climbing scaffolding for building construction, and in particular to a climbing scaffolding for building construction with an external protective device. Background Technology

[0002] Climbing scaffolding, also known as lifting scaffolding or hoisting scaffolding, is a type of scaffolding used in the construction of high-rise buildings. It can move up and down along the building. Due to the high working environment, external safety devices are installed on the climbing scaffolding to prevent accidents. Climbing scaffolding facilitates the construction of buildings and improves the efficiency of construction projects.

[0003] Existing climbing scaffolds used in building construction require lifting and lowering during use. During this process, the motor drives the scaffold to move up and down uniformly. This results in high tension on the cables and poses a significant risk, causing the scaffold to sway. Furthermore, lifting and lowering is inconvenient for construction work on each floor. Since construction workers inside the scaffold are at varying heights, the uniform lifting and lowering can lead to rushed local construction, hindering the unified and convenient construction process and affecting the overall quality of the building's exterior.

[0004] Therefore, this patent provides a climbing formwork for building construction with an external protective device that ensures stable lifting and lowering, minimizes stress when cables are pulled, and improves construction consistency, in order to solve such problems.

[0016] Compared with related technologies, the climbing scaffold for building construction with an external protective device provided by the present invention has the following beneficial effects:

[0017] This invention provides a climbing scaffold for building construction with an external protective device. A left main side plate and a left auxiliary side plate are fixed to the top of the left outer frame. A left drive wheel, a left rear wheel, and a left front wheel are movably connected between the middle of the left main side plate and the left auxiliary side plate. A left drive chain is sleeved on their outer sides. A left bottom wheel is fixed to the bottom of the left outer frame. A right main side plate and a right auxiliary side plate are fixed to the top of the right outer frame. A right bottom wheel is fixed to the bottom of the right outer frame. A right rear axle, a right middle axle, and a right front axle pass through the middle of the right main side plate and the right auxiliary side plate. A right... The rear wheel and right front wheel are connected to a right drive wheel fixed in the middle of the right central axle. A right drive chain is movably sleeved on the outside of the right drive wheel, right rear wheel, and right front wheel. The right outer frame contacts the front and rear sides of the right drive chain, and the left outer frame contacts the front and rear sides of the left drive chain. The climbing frame rises and falls along the inside of the left and right drive chains. At the same time, the left and right outer frames are set on the outside of the left and right drive chains. In this way, the left and right outer frames restrict the climbing frame during the rising and falling process, preventing violent shaking, ensuring the stability of the climbing frame at high altitudes, and improving the safety of the climbing frame device.

[0018] This invention provides a climbing scaffold for building construction with an external protective device. A secondary platform and a main platform are arranged in the middle of the left and right drive chains. A lower outer pipe is fixedly connected to the end of the secondary platform. A secondary lower connector is movably connected to the bottom of the lower outer pipe. A secondary lower limiter and a secondary upper connector are movably connected to the middle of the lower outer pipe. A secondary upper limiter is movably connected to the top of the lower outer pipe. A secondary support plate is fixed to the front of the secondary lower and upper connectors. A secondary telescopic rod is fixed to the front of the secondary lower and upper limiters. The secondary support plate and the secondary telescopic rod are movably connected. Extending the secondary telescopic rod causes the outer end of the secondary support plate to abut against the inner side of the right drive chain. Then, during the movement of the left and right drive chains, the secondary platform moves up and down along the limiting vertical rod. This reduces the load on the left and right motors during operation, allowing the secondary platform to rise and fall more quickly, extending the service life of the left and right motors, and reducing wear and tear on the left and right drive chains.

[0019] This invention provides a climbing scaffold for building construction with an external protective device. An upper outer pipe is fixed to the end of the main platform. A main lower connector is movably connected to the bottom of the upper outer pipe. A main lower limiter and a main upper connector are movably connected to the middle of the upper outer pipe. A main upper limiter is movably connected to the top of the upper outer pipe. A main support plate is fixed to the front of the main lower and main upper connectors. A main telescopic rod is fixed to the front of the main lower and main upper limiters. The main telescopic rod and the main support plate are movably connected. Positioned at the left rear and right front of the main platform, when the left and right drive chains move, the main telescopic rod is adjusted to bring the end of the main support plate into contact with the front of the left and right drive chains, thus raising the main platform. Adjusting the main telescopic rod brings the end of the main support plate into contact with the rear of the left and right drive chains, thus lowering the main platform. Before the main platform lowers, the limit crossbars need to be pulled out. This allows control of the raising and lowering of individual climbing frames, enabling construction personnel to raise and lower them to a comfortable height, facilitating the construction of the building facade and ensuring the overall consistency of the facade construction.

[0039] The working principle of this invention is as follows: A left main side plate 102 and a left auxiliary side plate 103 are fixed to the top of the left outer frame 101. A left drive wheel 107, a left rear wheel 108, and a left front wheel 109 are movably connected in the middle of the left main side plate 102 and the left auxiliary side plate 103. A left transmission chain 104 is sleeved on their outer sides. A right main side plate 202 and a right auxiliary side plate 203 are fixed to the top of the right outer frame 201. A right rear axle 211, a right middle axle 212, and a right front axle 213 pass through the middle of the right main side plate 202 and the right auxiliary side plate 203. A right transmission chain 204 is movably sleeved on the outer sides of the right drive wheel 207, the right rear wheel 208, and the right front wheel 209. The right outer frame 201 is in contact with the front and rear sides of the right transmission chain 204. The front and rear sides of 104 are in contact with the left outer frame 101. The climbing frame rises and falls along the interior of the left drive chain 104 and the right drive chain 204. At the same time, the left outer frame 101 and the right outer frame 201 are set on the outer sides of the left drive chain 104 and the right drive chain 204. In this way, the left outer frame 101 and the right outer frame 201 restrict the climbing frame during the rising and falling process, so as not to produce violent shaking. A secondary platform 401 and a main platform 301 are set in the middle of the left drive chain 104 and the right drive chain 204. A lower outer tube 402 is fixedly connected to the end of the secondary platform 401. A secondary lower connecting piece 403 is movably connected to the bottom of the lower outer tube 402. A secondary lower limiting piece 404 and a secondary upper connecting piece 405 are movably connected in the middle of the lower outer tube 402. A secondary upper limiter 406 is movably connected to the top of 402, connecting the secondary support plate 408 and the secondary telescopic rod 407. Extending the secondary telescopic rod 407 causes the outer end of the secondary support plate 408 to abut against the inner side of the right drive chain 204. During the movement of the left drive chain 104 and the right drive chain 204, the secondary platform 401 moves up and down along the limiting vertical rod 409, thus reducing the load on the left motor 106 and the right motor 206 during operation. An upper outer tube 304 is fixed to the end of the main platform 301. A main lower connector 305 is movably connected to the bottom of the upper outer tube 304.

A main lower limiter 306 and a main upper connector 307 are movably connected to the top of the upper outer tube 304.

The main telescopic rod 309 and the main support plate 310 are distributed on the left rear and right front of the main platform 301. When the left drive chain 104 and the right drive chain 204 move, the main telescopic rod 309 is adjusted to make the end of the main support plate 310 contact the front of the left drive chain 104 and the right drive chain 204, so that the main platform 301 rises. The main telescopic rod 309 is adjusted to make the end of the main support plate 310 contact the rear of the left drive chain 104 and the right drive chain 204, so that the main platform 301 falls. Before the main platform 301 falls, the limit crossbar 410 needs to be pulled out. The lifting and lowering of a single climbing frame can be controlled, and the construction personnel can lift and lower it to a comfortable height.
