Description
Technical Field
[0001] The present invention relates to the technical field of safe construction platforms, and specifically to a mobile safe construction platform. Background Technique
[0002] A safe construction platform generally refers to a working platform with certain functions built during the construction process of projects such as buildings and bridges to ensure the safety of construction workers and facilitate construction operations. The safe construction platform can lift workers, enabling them to be unrestricted by their own height and construct at high positions of buildings. To meet the flexible usage needs of workers, some mobile safe construction platforms have emerged on the market. These mobile safe construction platforms are usually relatively small and compact, facilitating movement to meet the usage needs of workers to move around at any time. However, when the existing mobile safe construction platforms are in use, the working environment is relatively harsh. Workers often need to place some building materials on the upper end of the safe construction platform. As a result, when workers stand on the upper end of the safe construction platform to construct a building, inevitably some building material residues will fall onto the upper end of the safe construction platform. Most of these building material residues are small particles such as sand. When workers move on the upper end of the safe construction platform, their feet stepping on the sand easily cause the workers to slip. At this time, the safe construction platform is in a state of lifting the workers, and the workers are at a high altitude, which easily leads to the workers falling from a height and has certain potential safety hazards. Therefore, it does not meet the existing needs, and for this reason, we propose a mobile safe construction platform. Summary of the Invention
[0003] The purpose of the present invention is to provide a mobile safe construction platform to solve the problem in the above background technique that when the mobile safe construction platform is in use, the working environment is relatively harsh. Workers often need to place some building materials on the upper end of the safe construction platform. As a result, when workers stand on the upper end of the safe construction platform to construct a building, inevitably some building material residues will fall onto the upper end of the safe construction platform. Most of these building material residues are small particles such as sand. When workers move on the upper end of the safe construction platform, their feet stepping on the sand easily cause the workers to slip. At this time, the safe construction platform is in a state of lifting the workers, and the workers are at a high altitude, which easily leads to the workers falling from a height and has certain potential safety hazards.

One end of the rubber airbag is fixedly installed with a jet hose; Oil collecting tank, which is fixedly installed at the lower end of the moving base. One side of the lower end of the oil collecting tank is fixedly installed with a connecting pipeline. The lower end of the oil collecting tank is fixedly installed with an extension cylinder.

A lateral cylinder is fixedly installed outside the extension cylinder. An anti-slip cone rod is slidably installed inside the lateral cylinder through a card slot.
[0005] Preferably, a second connecting rod is rotatably installed on one side of the scissor support. An electric hydraulic push rod is installed between the second connecting rod and the third connecting rod. The electric hydraulic push rod is rotatably connected to both the second connecting rod and the third connecting rod.
[0006] Preferably, the extrusion push plate is horizontally slidably connected to the hydraulic oil tank through a card slot. The air compression box is horizontally slidably connected to the air extrusion plate through a card slot.
[0007] Preferably, brake universal wheels are installed at the lower end of the moving base. The brake universal wheels are connected to the moving base by screws.
[0008] Preferably, a safety fence is installed at the upper end of the top lifting platform. The safety fence is welded to the top lifting platform. The rubber airbag is embedded inside the safety fence.
[0009] Preferably, an intake pipeline is installed on one side of the air compression box close to the multi-stage telescopic hydraulic rod. The intake pipeline is fixedly connected to the air compression box. One end of the intake pipeline is fixedly installed with an intake check valve.

[0011] Preferably, the upper end of the multi-stage telescopic hydraulic rod is slidably installed with a limit guide rail through a card slot. The limit guide rail limits the upper end of the multi-stage telescopic hydraulic rod, enabling the multi-stage telescopic hydraulic rod to slide under the lower end of the top lifting platform. At the same time, it ensures the lifting and supporting effect of the upper end of the multi-stage telescopic hydraulic rod on the top lifting platform. The top lifting platform is fixedly connected to the limit guide rail.
[0012] Preferably, the third connecting rod is slidably connected to the top lifting platform through a card slot, and the hydraulic oil tank is slidably connected to the hydraulic oil extrusion rod through a card slot.
[0013] Preferably, an air spray gun is installed at one end of the jet hose, and the air spray gun is fixedly connected to the jet hose.
[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. When the scissor support extends in the present invention, the first connecting rod on one side of the lower end of the scissor support gradually moves towards one side of the device following the movement of the scissor support. Then, the first connecting rod pulls the hydraulic oil extrusion rod to move, causing the extrusion push plate fixedly installed at one end of the hydraulic oil extrusion rod to extrude the hydraulic oil inside the hydraulic oil tank. Thus, the hydraulic oil is squeezed into the multi-stage telescopic hydraulic rod, making the multi-stage telescopic hydraulic rod gradually extend. Since the scissor support is in a gradually extending state, the extension of the multi-stage telescopic hydraulic rod is equal to the extension amount of the scissor support, reaching a dynamic balance. Then, the multi-stage telescopic hydraulic rod supports the lower end of the top lifting platform, enhancing the load-bearing strength of the device. Installing the air extrusion rod enables the scissor support to push the third connecting rod to move when it extends. The third connecting rod compresses the air inside the air compression box through the air extrusion plate and presses it into the rubber airbag through the inflation pipeline and inflation check valve, causing the rubber airbag to expand. Then, the air is stored in the rubber airbag, facilitating the staff to clean the top lifting platform when needed. Using the air spray gun to clean the top lifting platform can prevent the staff from slipping when moving on the upper end of the device because their feet step on the sand. This enhances the safety of the device. This device only needs the scissor support to extend to complete the lifting of the staff, collect and store energy from the air, facilitate the staff to clean the sand on the upper end of the top lifting platform, drive the multi-stage telescopic hydraulic rod to assist in limiting and supporting the top lifting platform, enhance the load-bearing capacity of the device, and greatly improve the practicality of the device. 2. When the present invention installs a telescopic bottom plate, when the extrusion push plate moves, part of the hydraulic oil enters the inside of the oil collecting tank through the connecting pipe, and then the hydraulic oil pressure inside the oil collecting tank is pressed into the extension cylinder, so that the telescopic bottom plate moves downward, and the stable cone rod is inserted into the ground, preventing the device from shaking easily when the device is collided by an external force during use, enhancing the stability of the device. Installing the lateral cylinder and the anti-slip cone rod can make part of the hydraulic oil inside the extension cylinder enter the inside of the lateral cylinder after the stable cone rod is inserted into the ground, and make the anti-slip cone rod inside the lateral cylinder obliquely penetrate into the ground under the action of the hydraulic oil, thereby preventing the device from moving and improving the stability of the device support; 3. When the present invention embeds the rubber air bag into the safety fence, the rubber air bag can be limited, so that the rubber air bag will not affect the staff's use of the device. At the same time, the rubber air bag can also increase the safety protection ability of the safety fence for the staff. The rubber air bag is horizontally placed at the lower end of the safety fence, which can improve the blocking ability of the safety fence and enhance the safety of the device. Installing the intake one-way valve can ensure that air enters the inside of the air compression box through the intake pipe, and the air inside the air compression box cannot be discharged through the intake pipe, ensuring that the air inside the air compression box moves along the specified path. Installing the air spray gun can facilitate the staff to discharge the air inside the rubber air bag, so that the air blows on the sand on the upper end of the top lifting platform under the action of the rubber air bag, thereby blowing away the sand, ensuring that the upper end of the top lifting platform is clean and reducing the cleaning difficulty of the device.

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.
[0018] Please refer to Figure 1-8 , an embodiment provided by the present invention: a mobile safety construction platform, including a mobile base 1: A scissor support 15 is rotatably installed at the upper end of the mobile base 1. One side of the lower end of the scissor support 15 is rotatably installed with a first connecting rod 20. The first connecting rod 20 is horizontally slidably connected to the mobile base 1. The outer part of the first connecting rod 20 is installed with a hydraulic oil extrusion rod 17 through a card slot. One side of the upper end of the mobile base 1 is installed with a hydraulic oil tank 2. One end of the hydraulic oil extrusion rod 17 is fixedly installed with an extrusion push plate 19. Installing the hydraulic oil extrusion rod 17 enables the first connecting rod 20 on one side of the lower end of the scissor support 15 to gradually move towards one side of the device following the movement of the scissor support 15 when the scissor support 15 extends. Furthermore, the first connecting rod 20 pulls the hydraulic oil extrusion rod 17 to move, causing the extrusion push plate 19 fixedly installed at one end of the hydraulic oil extrusion rod 17 to extrude the hydraulic oil inside the hydraulic oil tank 2. Then, the hydraulic oil is squeezed into the multi-stage telescopic hydraulic rod 3, causing the multi-stage telescopic hydraulic rod 3 to gradually extend. Since the scissor support 15 is in a gradually extending state, the extension of the multi-stage telescopic hydraulic rod 3 is equal to the extension amount of the scissor support 15, reaching a dynamic balance. Then, the multi-stage telescopic hydraulic rod 3 supports the lower end of the top lifting platform 4, enhancing the load-bearing strength of the device. The upper end surface of the hydraulic oil tank 2 is fixedly installed with the multi-stage telescopic hydraulic rod 3, and the upper end of the scissor support 15 is rotatably installed with the top lifting platform 4; The third connecting rod 22 is rotatably installed on the other side of the upper end face of the scissor bracket 15. An air extrusion rod 24 is installed outside the third connecting rod 22 through a card slot. Installing the air extrusion rod 24 enables the scissor bracket 15 to push the third connecting rod 22 to move when the scissor bracket 15 extends, so that the third connecting rod 22 compresses the air inside the air compression box 5 through the air extrusion plate 23 and presses it into the rubber airbag 14 through the inflation pipeline 9 and the inflation check valve 10, causing the rubber airbag 14 to expand, and then storing the air in the rubber airbag 14. This facilitates the staff to clean the top lifting platform 4 with an air spray gun 12 when needed, preventing the staff from slipping when stepping on sand at the upper end of the device, enhancing the safety of the device. One end of the air extrusion rod 24 is fixedly installed with an air extrusion plate 23. A side of the lower end face of the top lifting platform 4 away from the multi-stage telescopic hydraulic rod 3 is fixedly installed with an air compression box 5. A side of the air compression box 5 close to the multi-stage telescopic hydraulic rod 3 is fixedly installed with an inflation pipeline 9. One end of the inflation pipeline 9 is fixedly installed with an inflation check valve 10. One end of the inflation check valve 10 is fixedly installed with a rubber airbag 14. One end of the rubber airbag 14 is fixedly installed with a jet hose 11; The oil collecting tank 27 is fixedly installed at the lower end of the mobile base 1. A connecting pipeline 26 is fixedly installed on one side of the lower end of the oil collecting tank 27. An extension cylinder 28 is fixedly installed at the lower end of the oil collecting tank 27. A telescopic bottom plate 29 is slidably installed inside the extension cylinder 28 through a card slot. Installing the telescopic bottom plate 29 enables part of the hydraulic oil to enter the oil collecting tank 27 through the connecting pipeline 26 when the extrusion push plate 19 moves, and then the hydraulic oil inside the oil collecting tank 27 is pressed into the extension cylinder 28, thereby causing the telescopic bottom plate 29 to move downward, enabling the stable cone rod 30 to insert into the ground, preventing the device from shaking easily when the device is subjected to an external collision during use, and enhancing the stability of the device. The lower end of the telescopic bottom plate 29 is fixedly installed with a stable cone rod 30. A lateral cylinder 31 is fixedly installed on the outside of the extension cylinder 28. Installing the lateral cylinder 31 and the anti-slip cone rod 32 enables part of the hydraulic oil inside the extension cylinder 28 to enter the lateral cylinder 31 after the stable cone rod 30 is inserted into the ground, causing the anti-slip cone rod 32 inside the lateral cylinder 31 to obliquely penetrate into the ground under the action of the hydraulic oil, thereby preventing the device from moving and improving the stability of the device support. The anti-slip cone rod 32 is slidably installed inside the lateral cylinder 31 through a card slot.
[0019] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7, on one side of the scissor bracket 15, a second connecting rod 21 is rotatably installed. An electric hydraulic push rod 16 is installed between the second connecting rod 21 and the third connecting rod 22. The electric hydraulic push rod 16 is rotatably connected to both the second connecting rod 21 and the third connecting rod 22. The extrusion push plate 19 is horizontally slidably connected to the hydraulic oil tank 2 through a card slot. The air compression tank 5 is horizontally slidably connected to the air extrusion plate 23 through a card slot. At the lower end of the moving base 1, a brake universal wheel 18 is installed. The brake universal wheel 18 is connected to the moving base 1 by screws. At the upper end of the top lifting platform 4, a safety fence 8 is installed. The safety fence 8 is welded to the top lifting platform 4. The rubber airbag 14 is embedded inside the safety fence 8. Embedding the rubber airbag 14 in the safety fence 8 of this device can limit the rubber airbag 14, so that the rubber airbag 14 will not affect the staff's use of this device. At the same time, the rubber airbag 14 can also increase the safety protection ability of the safety fence 8 for the staff. The rubber airbag 14 is horizontally placed at the lower end of the safety fence 8, which can improve the blocking ability of the safety fence 8 and enhance the safety of the device.
[0020] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7 , on one side of the air compression tank 5 close to the multi-stage telescopic hydraulic rod 3, an intake pipe 6 is installed. The intake pipe 6 is fixedly connected to the air compression tank 5. At one end of the intake pipe 6, an intake one-way valve 7 is fixedly installed. Installing the intake one-way valve 7 can ensure that air enters the interior of the air compression tank 5 through the intake pipe 6, and the air inside the air compression tank 5 cannot be discharged through the intake pipe 6, ensuring that the air inside the air compression tank 5 moves along the specified path. On one side of the lower end of the safety fence 8, a controller 13 is installed. The controller 13 is fixedly connected to the safety fence 8. At the upper end of the multi-stage telescopic hydraulic rod 3, a limit guide rail 25 is slidably installed through a card slot. The limit guide rail 25 limits the upper end of the multi-stage telescopic hydraulic rod 3, enabling the multi-stage telescopic hydraulic rod 3 to slide under the lower end of the top lifting platform 4, and at the same time ensuring the lifting and supporting effect of the upper end of the multi-stage telescopic hydraulic rod 3 on the top lifting platform 4. The top lifting platform 4 is fixedly connected to the limit guide rail 25. The third connecting rod 22 is slidably connected to the top lifting platform 4 through a card slot. The hydraulic oil tank 2 is slidably connected to the hydraulic oil extrusion rod 17 through a card slot. At one end of the jet hose 11, an air spray gun 12 is installed. The air spray gun 12 is fixedly connected to the jet hose 11. Installing the air spray gun 12 can facilitate the staff to discharge the air inside the rubber airbag 14, so that the air, under the action of the rubber airbag 14, blows on the sand at the upper end of the top lifting platform 4, thereby blowing away the sand and ensuring that the upper end of the top lifting platform 4 is clean, reducing the cleaning difficulty of the device.
[0021] Working principle: When in use, the staff move this device to the working area, then place some building materials on the upper end of the top lifting platform 4. Next, the staff stand on the upper end of the top lifting platform 4, and then the electric hydraulic push rod 16 extends. The electric hydraulic push rod 16 adjusts the distance between the first connecting rod 20 and the second connecting rod 21, increasing the distance, thereby gradually extending the scissor support 15. Further, the scissor support 15 pushes the top lifting platform 4 upward to move. During the movement of the scissor support 15, the scissor support 15 drives the first connecting rod 20 and the third connecting rod 22 to move towards the center position of the device. Further, the first connecting rod 20 pulls the hydraulic oil extrusion rod 17 to move, causing the hydraulic oil extrusion rod 17 to extrude the hydraulic oil inside the hydraulic oil tank 2 through the extrusion push plate 19. Further, the hydraulic oil is pressed into the multi-stage telescopic hydraulic rod 3 under the action of pressure, causing the multi-stage telescopic hydraulic rod 3 to extend synchronously with the extension of the scissor support 15. Further, the multi-stage telescopic hydraulic rod 3 provides limit support for one side of the lower end of the top lifting platform 4, preventing the top lifting platform 4 from tilting and enhancing the load-bearing capacity of the device. When the extrusion push plate 19 moves, part of the hydraulic oil inside the hydraulic oil tank 2 enters the oil collecting tank 27 through the connecting pipe 26, causing the hydraulic oil inside the oil collecting tank 27 to be pressed into the extension cylinder 28, thereby causing the telescopic bottom plate 29 to move downward and the stabilizing cone rod 30 to be inserted into the ground. After the stabilizing cone rod 30 is inserted into the ground, part of the hydraulic oil inside the extension cylinder 28 enters the lateral cylinder 31, causing the anti-slip cone rod 32 inside the lateral cylinder 31 to obliquely penetrate into the ground under the action of the hydraulic oil. When the third connecting rod 22 moves, it will pull the air extrusion plate 23 to move through the air extrusion rod 24. Further, the air extrusion plate 23 extrudes the air inside the air compression box 5, causing the air inside the air compression box 5 to enter the rubber airbag 14 through the inflation pipe 9 and the inflation check valve 10. The volume of the rubber airbag 14 increases, enabling the rubber airbag 14 to provide a certain degree of safety limit for the staff. Next, the staff use the building materials to construct the building. When the staff need to clean the upper end of the top lifting platform 4, the staff only need to untie the jet hose 11 wound around the safety fence 8 and use the air spray gun 12 to blow the sand on the upper end of the top lifting platform 4 away, so as to keep the upper end of the top lifting platform 4 clean, prevent some sand from remaining on the top lifting platform 4, and avoid the staff slipping when their feet step on the sand when moving on the upper end of the device, enhancing the safety of the device. After the building materials on the upper end of the top lifting platform 4 are used up, the electric hydraulic push rod 16 retracts, thereby causing the scissor support 15 to retract and the multi-stage telescopic hydraulic rod 3 to retract. And the third connecting rod 22 pushes the air extrusion plate 23 to move, causing the air to enter the air compression box 5 through the air inlet pipe 6 and the air inlet check valve 7. When the top lifting platform 4 descends to the lowest point of the stroke, the staff can walk down from the top lifting platform 4. Installing the hydraulic oil extrusion rod 17 on this device can enable the scissor support 15 toOne side of the lower end of the scissor bracket 15, the first connecting rod 20 gradually moves towards one side of the device following the movement of the scissor bracket 15. Then, the first connecting rod 20 pulls the hydraulic oil extrusion rod 17 to move, causing the extrusion push plate 19 fixedly installed at one end of the hydraulic oil extrusion rod 17 to extrude the hydraulic oil inside the hydraulic oil tank 2. Thus, the hydraulic oil is squeezed into the inside of the multi-stage telescopic hydraulic rod 3, causing the multi-stage telescopic hydraulic rod 3 to gradually extend. Since the scissor bracket 15 is in a gradually extending state, the extension of the multi-stage telescopic hydraulic rod 3 is equal to the extension amount of the scissor bracket 15, reaching a dynamic balance. Then, the multi-stage telescopic hydraulic rod 3 supports the lower end of the top lifting platform 4, enhancing the load-bearing strength of the device. Installing the air extrusion rod 24 enables the scissor bracket 15 to push the third connecting rod 22 to move when the scissor bracket 15 extends. The third connecting rod 22 compresses the air inside the air compression tank 5 through the air extrusion plate 23 and presses it into the rubber airbag 14 through the inflation pipeline 9 and the inflation check valve 10, causing the rubber airbag 14 to expand. Thus, the air is stored in the rubber airbag 14, facilitating the staff to clean the top lifting platform 4 with the air spray gun 12 when needed, preventing the staff from slipping when their feet step on the sand while moving on the upper end of the device, and enhancing the safety of the device. Embedding the rubber airbag 14 in the safety fence 8 of this device can limit the rubber airbag 14, preventing the rubber airbag 14 from affecting the staff's use of this device. At the same time, the rubber airbag 14 can also increase the safety protection ability of the safety fence 8 for the staff. The rubber airbag 14 is horizontally placed at the lower end of the safety fence 8, which can improve the blocking ability of the safety fence 8 and enhance the safety of the device. Installing the intake check valve 7 can ensure that the air enters the inside of the air compression tank 5 through the intake pipeline 6, and the air inside the air compression tank 5 cannot be discharged through the intake pipeline 6, ensuring that the air inside the air compression tank 5 moves along the specified path. Installing the air spray gun 12 can facilitate the staff to discharge the air inside the rubber airbag 14, causing the air to blow on the sand on the upper end of the top lifting platform 4 under the action of the rubber airbag 14, and then blowing away the sand, ensuring that the upper end of the top lifting platform 4 is clean and reducing the cleaning difficulty of the device. Installing the telescopic bottom plate 29 enables part of the hydraulic oil to enter the oil collecting tank 27 through the connecting pipeline 26 when the extrusion push plate 19 moves. Then, the hydraulic oil inside the oil collecting tank 27 is pressed into the extension cylinder 28, causing the telescopic bottom plate 29 to move downward and the stabilizing cone rod 30 to insert into the ground, preventing the device from shaking easily when the device is externally collided during use and enhancing the stability of the device. Installing the lateral cylinder 31 and the anti-slip cone rod 32 enables part of the hydraulic oil inside the extension cylinder 28 to enter the lateral cylinder 31 after the stabilizing cone rod 30 inserts into the ground. The anti-slip cone rod 32 inside the lateral cylinder 31 obliquely pierces into the ground under the action of the hydraulic oil, thus preventing the device from moving and improving the stability of the device support.,
