The structures of the above two inventions have the following deficiencies:

1. It is necessary to transport the flowable material to the inside of the counterweight box in advance, then take the counterweight box out of the traction cable and put it on the device of the required counterweight, and finally the workers can stand on the construction platform, which is a complicated and time-consuming process. It is laborious, and the counterweight box is a rectangular shell structure. After the flowable material enters the interior of the counterweight box, it will cause uneven distribution, so that the supporting effect of the counterweight box needs to be improved.

A safety protection device for a construction platform of a building exterior wall with high safety and a use method thereof.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide a safety protection device and a use method for a construction platform of a building exterior wall.

For this purpose, the present invention adopts the following technical solutions:

A method of using a safety protection device for a building exterior wall construction platform, comprising the following steps:

S1: Preparations before the device is used:

The device is pushed to the side of the outer wall of the building by the push handle, the protective sponge improves the gripping comfort, and the gripping groove is used for grasping. The wall of the outer wall is fitted, and the elastic rod ensures that the lap wheel has a certain telescopic distance, which can meet the requirements of the building exterior wall with different uneven surface conditions. When the worker stands on the construction platform on the top of the support frame, the four lap joints The wheel can ensure that the support frame and the wall keep a certain distance to prevent workers from accidentally touching the wall during work and get injured. At the same time, when the support frame is raised and lowered, it can ensure the stable lifting of the support frame, both of which can ensure the construction The effect of the platform is stable. Several installation holes are used to fix the support frame and the construction platform. The construction platform can be a hanging basket and other facilities. Two limit blocks limit the two ends of the construction platform to prevent it from shaking and ensure the safety of workers. When the four lap wheels are completely in contact with the building wall, lock the four universal wheels to prevent slipping.

S2: Hover maintenance of construction platform:

In the initial state, when the construction platform on the top of the support frame is not loaded with workers and goods, because the rack is meshed with the gear, and the traction rope is blocked by the anti-dropping column, in addition, the circular housing is blocked by the anti-dropping cap. It cannot achieve its own rise, so the rack cannot drive the gear to rotate, so it cannot drive the runner coaxial with the gear to rotate, so that the traction rope does not work, and the support makes the vacant construction platform at the top of the support frame in a hovering state. After entering the construction platform at the top of the support frame, the support frame is affected by gravity and should start to descend, but like the above factors, the anti-drop cap restricts the ascent of the circular housing, so that the anti-drop column restricts the operation of the traction rope. Therefore, the premise adjustment for the support frame to descend is not established, thereby ensuring the safety of the construction platform.

S3: Height adjustment of construction platform:

When the worker completes the wall construction of the building exterior wall of a certain height, the controller starts the servo motor to drive the disc to rotate. Since the extrusion rod is inserted into the storage barrel, the extrusion rod is far away from one end of the storage barrel and the disk. They are hinged with the two ends of the connecting rod respectively, thus driving the extrusion rod to squeeze the inner part of the storage barrel to the end away from the servo motor, and extruding the flowable material inside it to the outside. When the flowable material enters the circular container After the inside of the shell, firstly fill the inside of the conduit directly. Since there are several through holes designed on the outer wall of the conduit in the circumferential direction, the inner bottom of the circular housing shell is first filled. It is also filled up, and the flowable material that continues to fall can only slide evenly from the top of the conical guide table to the surrounding, so as to fill the inner top of the circular container evenly around the top, compared with the existing counterweight. The structure can fill the interior of the circular container shell with flowable substances from low to high and evenly, without causing uneven distribution of the flowable substances in the circular container shell, which is beneficial to ensure the circular container The stability of the shell after filling further ensures the stability of the support frame and the construction platform, and plays an auxiliary role in the safety protection of the construction platform.

When the flowable substance is gradually transported to the inside of the circular container, the weight of the circular container gradually increases. Since the lap shell is fixedly connected to the circular container, each limit rod is connected to the lap shell and the support block. Plug and connect, thus driving the circular accommodating shell to gradually descend on the outer wall of the limit rod, and the two buffer springs collide with the overlapping shell, thus ensuring that the circular accommodating shell descends slowly, when the circular accommodating shell descends , the pull rod pulls the traction rope down through the anti-detachment column. Because the traction rope is sleeved with the runner, the runner and the support rod are connected in rotation, thus driving the runner to rotate, and because the runner and the gear are coaxial, the gear and the rack are meshed connected, so as to drive the rack to rise through the gear. Since the rack is fixedly connected to the support frame, it drives the support frame to rise. After the rise, the flowable material in the circular container can ensure the hovering of the construction platform. After the work is completed, The flowable material is extracted from the circular container, the construction platform descends with the support frame, and the workers come out from the construction platform. Compared with the prior art, the flowable material is filled into the circular container to adjust the The height of the construction platform on the top of the support frame can not only ensure the upward displacement of the construction platform by a certain distance to meet certain construction requirements, but also the support frame drives the construction platform to rise slowly, and when it rises, it also ensures the safety of the personnel inside the construction platform. Safety, achieves the effect of safety protection for the construction platform, and further increases the practicability of the device.

S4: Evacuation of flowable substances:

Due to the inconsistency between the number of construction workers and the weight of the items loaded on the construction platform each time, when the height of the construction platform is adjusted, the amount of flowable substances transported into the circular container is also different. During construction, the suction pump and solenoid valve are activated by the controller, so that the discharge port is opened, and all the flowable substances in the circular holding tank are sucked into the suction pump through the suction pipe, and then all transported to the suction pump through the conveying pipe. In order to store the inside of the barrel for the next filling of the circular container with the flowable material, the liquid level sensor can detect the remaining amount of the flowable material inside the circular container in real time. It is evacuated, and then the suction pump is powered off by the controller, and the continuous pumping is stopped.

Beneficial effects of the present invention:

1. The present invention limits the descending of the support frame by designing the support frame, the circular accommodating shell, two traction assemblies and four supporting assemblies, and uses the circular accommodating shell that cannot rise, so that the vacant construction platform at the top of the supporting frame is In the hovering state, compared with the prior art, after the worker stands on the construction platform, the construction platform can play a good supporting effect on the worker, thereby ensuring the safety of the worker and playing a role in safety protection.

2. In the present invention, by designing the conveying mechanism, when the worker completes the wall work of the outer wall of a certain building, the support can be driven by the circular housing shell by adding a flowable substance to the inside of the circular housing shell without the need for the worker to come down. The frame rises, thereby driving the construction platform inside the support frame to rise. Compared with the prior art, it can not only ensure that the construction platform is displaced upward by a certain distance to meet certain construction requirements, but also the support frame drives the construction platform to rise slowly. When rising, the safety of the personnel inside the construction platform is also ensured, the effect of safety protection for the construction platform is achieved, and the practicability of the device is further increased.

3. By designing four L-shaped rods and four lap wheels, the present invention can reduce the shaking of the construction platform by using the lap joints between the four lap wheels and the construction wall when workers construct the outer wall of the building. , Compared with the existing technology, not only will it not affect the construction of workers, but also after the shaking of the construction platform is reduced, the stability of the construction platform can be ensured, thereby reducing potential safety hazards. The elastic rod is used to ensure that the lap wheel has a certain expansion and contraction distance to meet the external wall of buildings with different concave and convex surface conditions.

4. In the present invention, by designing a conduit, a conical guide table and a plug-in column inside the circular container, the process of adding flowable substances to the interior of the circular container is slow and uniform, thereby ensuring the circular container. Compared with the existing structure of the counterweight box, the inside of the circular container can be filled with flowable substances from low to high and evenly, without causing the internal flow of the circular container. The uneven distribution of the fluid substances is beneficial to ensure the stability of the circular housing shell after filling, further ensuring the stability of the support frame and the construction platform, and playing an auxiliary role in the safety protection of the construction platform.

In the initial state, when the construction platform on the top of the support frame 30 is not loaded with workers and objects, the rack 31 is meshed with the gear 322, and the traction rope 321 is blocked by the anti-falling column 324. In addition, the circular housing 31 Blocked by the anti-off cap, it cannot achieve its own rise, so the rack 31 cannot drive the gear 322 to rotate, and thus cannot drive the runner 323 coaxial with the gear 322 to rotate, so that the traction rope 321 does not work, and the support frame 30 is supported. The vacant construction platform at the top is in a hovering state. When workers enter the construction platform at the top of the support frame 30, the support frame 30 is affected by gravity and should have started to descend. As a result, the anti-separation column 324 restricts the operation of the traction rope 321, thus making the premise adjustment of the support frame 30 to descend cannot be established, thereby ensuring the safety of the construction platform.

S3: Height adjustment of construction platform:

When the worker completes the wall construction of the building exterior wall of a certain height, the controller 2 starts the servo motor 420, thereby driving the disc 422 to rotate. Since the extrusion rod 423 is inserted into the storage bucket 41, the extrusion rod 423 is far away from the storage One end of the barrel 41 and the disc 422 are hinged with the two ends of the connecting rod 421 respectively, thus driving the extrusion rod 423 to squeeze the end away from the servo motor 420 in the interior of the storage barrel 41, so as to push the flowable material inside it to the outside. Squeeze, after the flowable substance enters the inside of the circular container 31, the interior of the conduit 311 is directly filled first. Since the outer wall of the conduit 311 in the circumferential direction is designed with a number of through holes, the circular container The inner bottom of the shell 31 is filled all around, and when it is filled, the interior of the conduit 311 is also filled, and the flowable substances that continue to fall can only slide evenly from the top of the conical guide table 312 to the surrounding, so that the circular The inner and top sides of the accommodating shell 31 are evenly filled. Compared with the existing counterweight structure, the interior of the circular accommodating shell 31 can be filled with flowable substances from low to high and evenly, without causing a circular shape. The uneven distribution of the flowable substances inside the accommodating shell 31 helps to ensure the stability of the circular accommodating shell 31 after filling, further ensures the stability of the support frame 30 and the construction platform, and plays an important role in the safety protection of the construction platform. Supporting role.

When the flowable substance is gradually transported to the inside of the circular containing shell 31, the weight of the circular containing shell 31 gradually increases. Since the overlapping shell 330 is fixedly connected to the circular containing shell 31, each limit rod 333 is connected to the overlapping shell 31. The connecting shell 330 is inserted into the support block, thereby driving the circular accommodating shell 31 to gradually descend on the outer wall of the limit rod 333, and the two buffer springs 332 collide with the overlapping shell 330, thereby ensuring that the circular accommodating shell 31 descends at a constant rate. Slowly, when the circular housing 31 descends, the pull rod 320 pulls the traction rope 321 downward through the anti-drop column 324. Since the traction rope 321 is sleeved with the runner 323, the runner 323 is rotatably connected with the support rod, thereby driving The runner 323 rotates, and because the runner 323 is coaxial with the gear 322, the gear 322 is meshed and connected with the rack 31, thereby driving the rack 31 to rise through the gear 322. Since the rack 31 is fixedly connected with the support frame 30, the support frame is further driven. 30 rises. After the rise, the flowable material in the circular container 31 can ensure the hovering of the construction platform. After the work is completed, the flowable material is extracted from the circular container 31, and the construction platform descends with the support frame 30. The workers come out from the construction platform again. Compared with the prior art, the height of the construction platform on the top of the support frame 30 is adjusted by filling the inside of the circular housing shell 31 with flowable substances, which can not only ensure that the construction platform is displaced upward by a certain distance , to meet certain construction requirements, and at the same time the support frame 30 drives the construction platform to rise slowly, so that the safety of the personnel inside the construction platform is also ensured during the rise, and the effect of safety protection for the construction platform is achieved, which further increases the cost. usability of the device.

S4: Evacuation of flowable substances:

Since the number of construction workers and the weight of the items loaded on the construction platform are inconsistent each time, when the height of the construction platform is adjusted, the amount of flowable substances transported into the circular container shell 31 is also different. During the construction of the wall, the suction pump 400 and the solenoid valve 403 are activated by the controller 2, so that the discharge port is opened, and all the flowable substances in the circular holding tank are sucked into the suction pump 400 through the suction pipe 402, and then The liquid level sensor 315 can detect the remaining amount of the flowable material inside the circular container 31 in real time by conveying all the conveying pipe 401 to the interior of the storage bucket 41 so that the flowable material can fill the circular container 31 next time. , when the detected value is zero, it means that the pump has been evacuated, and then the suction pump 400 is powered off by the controller 2, and the continuous pumping is stopped.

The working principle of the present invention: when the safety protection of the construction platform is carried out, the device is first pushed to the side of the building outer wall by the push handle, the protective sponge improves the comfort of grasping, and the grasping groove is used for grasping.

When the chassis 1 is pushed close to the clamped outer wall, the four lap wheels 322 are attached to the wall of the building's outer wall, and the elastic rods 321 ensure that the lap wheels 322 have a certain telescopic distance to meet the requirements of different uneven surfaces. In the case of the external wall of the building, when the worker stands on the construction platform on the top of the support frame 30, the four lap wheels 322 can ensure that the support frame 30 and the wall surface keep a certain distance, so as to prevent the worker from accidentally touching the wall during work. At the same time, when the support frame 30 is lifted and lowered, the lifting and lowering of the support frame 30 can be ensured smoothly, and both of them can ensure the stability of the construction platform. Several installation holes are used to fix the support frame 30 and the construction platform. The construction platform can It is a hanging basket and other facilities. Two limit blocks limit the two ends of the construction platform to prevent it from shaking and ensure the safety of workers. When the four lap wheels 322 are completely attached to the building wall, the four universal The wheels are locked to prevent slipping.

In the initial state, when the construction platform on the top of the support frame 30 is not loaded with workers and objects, the rack 31 is meshed with the gear 322, and the traction rope 321 is blocked by the anti-falling column 324. In addition, the circular housing 31 Blocked by the anti-off cap, it cannot achieve its own rise, so the rack 31 cannot drive the gear 322 to rotate, and thus cannot drive the runner 323 coaxial with the gear 322 to rotate, so that the traction rope 321 does not work, and the support frame 30 is supported. The vacant construction platform at the top is in a hovering state. When workers enter the construction platform at the top of the support frame 30, the support frame 30 is affected by gravity and should have started to descend. As a result, the anti-separation column 324 restricts the operation of the traction rope 321, thus making the premise adjustment of the support frame 30 to descend cannot be established, thereby ensuring the safety of the construction platform.

When the worker completes the wall construction of the building exterior wall of a certain height, the controller 2 starts the servo motor 420, thereby driving the disc 422 to rotate. Since the extrusion rod 423 is inserted into the storage bucket 41, the extrusion rod 423 is far away from the storage One end of the barrel 41 and the disc 422 are hinged with the two ends of the connecting rod 421 respectively, thus driving the extrusion rod 423 to squeeze the end away from the servo motor 420 in the interior of the storage barrel 41, so as to push the flowable material inside it to the outside. Squeeze, after the flowable substance enters the inside of the circular container 31, the interior of the conduit 311 is directly filled first. Since the outer wall of the conduit 311 in the circumferential direction is designed with a number of through holes, the circular container The inner bottom of the shell 31 is filled all around, and when it is filled, the interior of the conduit 311 is also filled, and the flowable substances that continue to fall can only slide evenly from the top of the conical guide table 312 to the surrounding, so that the circular The inner and top sides of the accommodating shell 31 are evenly filled. Compared with the existing counterweight structure, the interior of the circular accommodating shell 31 can be filled with flowable substances from low to high and evenly, without causing a circular shape. The uneven distribution of the flowable substances inside the accommodating shell 31 helps to ensure the stability of the circular accommodating shell 31 after filling, further ensures the stability of the support frame 30 and the construction platform, and plays an important role in the safety protection of the construction platform. Supporting role.

When the flowable substance is gradually transported to the inside of the circular containing shell 31, the weight of the circular containing shell 31 gradually increases. Since the overlapping shell 330 is fixedly connected to the circular containing shell 31, each limit rod 333 is connected to the overlapping shell 31. The connecting shell 330 is inserted into the support block, thereby driving the circular accommodating shell 31 to gradually descend on the outer wall of the limit rod 333, and the two buffer springs 332 collide with the overlapping shell 330, thereby ensuring that the circular accommodating shell 31 descends at a constant rate. slow.

When the circular housing 31 descends, the pull rod 320 pulls the traction rope 321 downward through the anti-drop column 324. Since the traction rope 321 is sleeved with the runner 323, the runner 323 is rotatably connected to the support rod, thus driving the runner 323 to rotate , and because the runner 323 is coaxial with the gear 322, the gear 322 is meshed and connected with the rack 31, thereby driving the rack 31 to rise through the gear 322. Since the rack 31 is fixedly connected to the support frame 30, it drives the support frame 30 to rise and rise. Then, the flowable material in the circular container 31 can ensure the hovering of the construction platform. After the work is completed, the flowable material is extracted from the circular container 31. When the platform comes out, compared with the prior art, the height of the construction platform on the top of the support frame 30 is adjusted by filling the inside of the circular housing shell 31 with a flowable material, which can not only ensure the upward displacement of the construction platform by a certain distance, but also satisfy a certain requirement. At the same time, the rising speed of the construction platform driven by the support frame 30 is slow, thus ensuring the safety of the personnel inside the construction platform during the rising, achieving the effect of safety protection for the construction platform, and further increasing the practicability of the device. .

Since the number of construction workers and the weight of the items loaded on the construction platform are inconsistent each time, when the height of the construction platform is adjusted, the amount of flowable substances transported into the circular container shell 31 is also different. During the construction of the wall, the suction pump 400 and the solenoid valve 403 are activated by the controller 2, so that the discharge port is opened, and all the flowable substances in the circular holding tank are sucked into the suction pump 400 through the suction pipe 402, and then The liquid level sensor 315 can detect the remaining amount of the flowable material inside the circular container 31 in real time by conveying all the conveying pipe 401 to the interior of the storage bucket 41 so that the flowable material can fill the circular container 31 next time. , when the detected value is zero, it means that the pump has been evacuated, and then the suction pump 400 is powered off by the controller 2, and the continuous pumping is stopped.
