Description

Technical Field

[0001] This utility model relates to the field of construction machinery and equipment technology, specifically to a mobile hydraulic lifting bricklaying platform. Background Technology

[0002] Currently, in the construction industry, especially in the construction of factories and large shopping malls, and the installation and maintenance of industrial equipment and pipelines, the construction of walls, the installation, maintenance, and replacement of electrical equipment and pipelines all require workers to perform tasks at heights, and necessitate the transportation of large quantities of construction materials. This involves the coordinated use of various tools such as scaffolding, elevators, and forklifts. This results in low efficiency, high costs, a large labor force, and unstable coordination, ultimately leading to more safety hazards.

[0003] Existing technological defects and shortcomings:

[0004] 1. Currently, various types of lifting platforms have appeared on the market, such as the lifting platforms disclosed in patent documents CN115030469A, CN219823596U and CN219860458U. Although they integrate multiple functions such as carrying people, carrying goods, electric lifting, and electric drive, they simply superimpose existing functional technologies such as hydraulic lifting and electric drive onto the platform equipment, while ignoring the safety of use. Although they simplify the diversity of tools, they also increase more safety hazards.

[0005] 2. Examples of safety hazards:

[0006] ① If the working platform is not locked at its highest point and can still move, or if the working platform can still be raised or lowered while moving, there is a situation where the working platform is raised or lowered under load, which can easily lead to safety accidents such as rollover; the electric drive uses an electric tricycle drive axle assembly, which has sufficient power but high speed, and does not have an emergency stop switch or brake function, making it very easy to slip or collide during driving.

[0007] ② The platform is assembled from multiple small platforms, which enclose the lifting gantry in the middle. Although the overall platform area is large, the gaps between the gantry make it difficult for people to move around, and it is easy to cause bumps and trips.

[0008] The above are two simple examples of safety hazards. Currently, there are still many safety hazards in equipment on the market in terms of hydraulic lifting, platform structure, and electric drive. Utility Model Content

[0009] In view of the problems and shortcomings of the existing technology, this utility model provides a mobile hydraulic lifting bricklaying platform.

[0010] The technical solution of this utility model is as follows:

[0011] A mobile hydraulic lifting bricklaying platform, comprising:

[0012] The chassis includes a frame, on which a traveling mechanism and leveling outriggers are mounted;

[0013] The lifting mechanism includes a gantry connected to both sides of the chassis frame, a telescopic frame slidably connected to the gantry, a hydraulic cylinder that drives the telescopic frame to lift synchronously, and a hydraulic power system that controls the operation of the hydraulic cylinder.

[0014] The work platform is connected to the chassis via a lifting mechanism and moves up and down under the drive of the lifting mechanism for carrying people and goods.

[0015] The aforementioned walking mechanism is equipped with a level switch, which communicates with the electrical control cabinet to detect the levelness of the wall-cutting platform. The electrical control cabinet controls the energization of the walking mechanism based on the levelness. During operation, if the level switch detects that the level bubble is centered, the electrical control cabinet activates the hydraulic power system circuit, allowing the lifting mechanism to drive the work platform for lifting operations. Otherwise, the electrical control cabinet disconnects the hydraulic power system circuit, rendering the lifting operation ineffective and the lifting mechanism inactive. This ensures that the wall-cutting platform of this invention can only perform lifting movements when it is level, preventing safety accidents caused by lifting operations when the equipment is tilted.

[0016] The gantry is equipped with a lower limit switch, which communicates with the electrical control cabinet to detect whether the lifting mechanism is at the lower limit position. The electrical control cabinet controls the energization of the traveling mechanism based on the lower limit position detection result. When the work platform descends to the lowest point and triggers the lower limit switch, the electrical control cabinet connects the traveling mechanism to the power supply, and the traveling mechanism is started by operating the corresponding start button. Otherwise, the traveling mechanism is disconnected from the power supply and cannot be started by operating the corresponding start button, thus preventing the traveling mechanism from starting while the work platform is at a high position, which could cause the wall-cutting platform to collapse due to excessive movement.

[0017] The frame is equipped with outrigger switches to detect whether the leveling outriggers are on the ground. These switches communicate with the electrical control cabinet, which controls the hydraulic power system of the lifting mechanism based on the detection results from the outrigger switches. Specifically, each of the four leveling outriggers is equipped with an outrigger switch. When the leveling outrigger is on the ground and under force, the outrigger switch is triggered, and the electrical control cabinet connects the hydraulic power system to the power supply. Only then can the hydraulic power system operate, allowing the lifting mechanism to function effectively and drive the work platform upwards. This effectively prevents the work platform from being raised or lowered without stable support, reducing the risk of tipping over. Furthermore, the equipment uses the four leveling outriggers for leveling, ensuring the overall machine's levelness is within 0.5 degrees before the lifting mechanism can operate; otherwise, it cannot raise or lower.

[0018] According to a specific embodiment, the gantry is also equipped with a protective limit switch, which is communicatively connected to the electrical control cabinet. This switch disconnects the hydraulic power system when the bottom of the work platform descends to 2 meters, thus stopping the lifting mechanism's descent. In actual use, the work platform stops descending at a height of 2 meters, and the descent can only be restarted after pressing the corresponding lifting mechanism's descent button for 3 seconds. This allows the operator above to observe the situation below the work platform and ensure there are no people or obstacles before proceeding with the descent, reducing the risk of personal injury or equipment damage.

[0019] The gantry is also equipped with an upper limit switch, which is connected to the electrical control cabinet to limit the upper limit position of the lifting mechanism.

[0020] According to a specific embodiment, the hydraulic power system is mounted on the chassis frame and includes an oil tank. The outlet end is connected to a main block valve, which is powered by a motor. The outlet end is connected to a flow divider valve, and the outlet ends of the flow divider valves are respectively connected to hydraulic cylinders installed in the side masts. The main block valve is also equipped with a solenoid directional valve, which has an emergency pull rod. The emergency pull rod is used to manually force the lifting mechanism to descend in case of platform failure. Specifically, when the equipment malfunctions and cannot operate while in the raised state, the emergency pull rod can be pulled to lower the work platform.

[0021] Furthermore, a pressure switch is installed on the pipeline between the main block valve and the diverter valve. This pressure switch is communicatively connected to the electrical control cabinet and is used to detect the pressure of the hydraulic power system. The electrical control cabinet controls the motor operation of the main block valve based on the pressure. The electrical control cabinet determines the load capacity of the work platform based on the pressure from the pressure switch. When the load capacity of the work platform exceeds the rated load, the electrical control cabinet disconnects the motor from the power supply, preventing hydraulic oil from entering the hydraulic cylinder through the main block valve. Therefore, the lifting mechanism cannot drive the work platform to perform the lifting action. This prevents safety accidents caused by overloading the work platform during lifting.

[0022] According to one specific embodiment, the walking mechanism includes a drive wheel, a driven wheel, and a drive handle.

[0023] The drive wheel is connected to the chassis frame and located on one side of the gantry. It is driven by a drive motor, which is electrically connected to the electrical control cabinet fixed on the frame. A brake is also connected to the control cabinet. The brake automatically applies when the corresponding button is pressed, as the controller is set to control the device. This prevents the device from sliding on sloping ground and causing accidents such as collisions with people or damage to property.

[0024] Driven wheels are located below the chassis frame and work in conjunction with drive wheels to enable the chassis to move automatically on the ground.

[0025] The drive handle is connected to the chassis frame via a horizontal support and is located above the drive wheels. It is equipped with a start / stop switch and an emergency stop switch to control the drive motor. The horizontal switch is connected to the horizontal support. Operating the start / stop switch controls the drive motor to rotate the drive wheels, enabling automatic movement. Additionally, in case of an emergency during operation, the emergency stop switch can be pressed with both hands or the body to achieve emergency braking.

[0026] According to one specific embodiment, two movable maintenance support pipes are placed on the chassis frame to support the lifting mechanism and prevent the work platform from descending during maintenance. When the work platform is raised, the support pipes are installed below the lifting mechanism to provide mechanical support to the gantry and prevent the platform from descending, thus protecting the maintenance personnel below.

[0027] According to one specific embodiment, the gantry is also equipped with a hazard alarm flashing light, which is communicatively connected to the electrical control cabinet. During the ascent and descent of the work platform, the hazard alarm flashing light activates to emit an audible and visual alarm, serving as a warning function.

[0028] According to one specific embodiment, the work platform includes a cargo platform and a guardrail gate.

[0029] The cargo platform is installed between the masts on both sides of the lifting mechanism, and includes a main platform and a pedestrian platform arranged side by side. Specifically, the cargo platform is composed of a 3112mm*1192mm main platform and a 3000mm*400mm pedestrian platform. The entire platform is placed in the middle of the lifting mast. The interior of the platform is flat and free of any obstacles, providing ample space for personnel to move around and avoiding contact with other equipment and structural components outside the platform.

[0030] The guardrails are connected around the loading platform and include a fixed guardrail fixed to the inside of the gantry, a side guardrail inserted into one side of the fixed guardrail, and a loading guardrail gate and a personnel guardrail gate set on the opposite side of the side guardrail.

[0031] Specifically, the fixed guardrails are bolted in place and cannot be removed unless absolutely necessary, isolating personnel from the lifting mechanism to prevent personal injury from contact; the side guardrails are plug-in connected, allowing for easy removal and facilitating personnel work while freeing up more space; the material loading guardrails are double-leaf gates, while the personnel loading guardrails are single-leaf gates. The material loading guardrails open outwards when loading materials and are manually locked when closed; the personnel loading guardrails open inwards when people are on board and automatically close and lock after boarding.

[0032] According to one specific embodiment, the lifting mechanism also includes a chain drive assembly connected to the telescopic frame, with a chain guard net provided on the side of the telescopic frame facing the work platform. This completely isolates the chain drive assembly from the operators on the work platform, preventing accidents.

[0033] The beneficial effects of this utility model are:

[0034] This invention, while fulfilling the basic requirements of high load capacity, lifting function, and auxiliary walking function, significantly enhances the safety of the equipment, filling the safety gaps in such products. It effectively prevents the equipment from lifting or lowering in an tilted or unsupported state, reducing the occurrence of tipping accidents and minimizing damage to the equipment itself or injury to personnel during operation, thus improving overall safety.

[0035] This utility model is designed in multiple aspects, including circuits, electrical control, hydraulic systems, drive systems, and mechanical structures. It fully considers various working conditions, user experiences, and potential problems, and has developed multiple safety solutions in advance. Attached Figure Description

[0040] The technical means adopted to achieve the intended purpose of this utility model will be further described below with reference to the accompanying drawings of the embodiments of this utility model.

[0041] Example

[0042] See Figure 1 and Figure 2 As shown, a mobile hydraulic lifting bricklaying platform includes:

[0043] The chassis 1 includes a frame 11, on which a walking mechanism and leveling outriggers 12 are provided;

[0044] The lifting mechanism 2 includes a gantry 21 connected to both sides of the frame 11 of the chassis 1, a telescopic frame 22 slidably connected to the gantry 21, a hydraulic cylinder 23 that drives the telescopic frame 22 to lift synchronously, and a hydraulic power system 24 that controls the operation of the hydraulic cylinder 23.

[0045] The work platform 3 is connected above the chassis 1 via the lifting mechanism 2 and moves up and down under the drive of the lifting mechanism 2 for carrying people and goods.

[0046] The aforementioned walking mechanism is equipped with a level switch 17, which is communicatively connected to the electrical control cabinet 4. This level switch detects the levelness of the wall-cutting platform, and the electrical control cabinet 4 controls the operation of the lifting mechanism 2 based on the levelness. During operation, if the level switch 17 detects that the level bubble is centered, the electrical control cabinet 4 activates the circuit of the hydraulic power system 24, allowing the lifting mechanism 2 to drive the work platform 3 for lifting operations. Otherwise, the electrical control cabinet 4 disconnects the circuit of the hydraulic power system 24, rendering the lifting operation ineffective and the lifting mechanism 2 stationary. This ensures that the wall-cutting platform of this invention is level before the work platform 3 can perform lifting movements, preventing safety accidents caused by lifting operations when the equipment is tilted.

[0047] The aforementioned gantry 21 is equipped with a lower limit switch 5, which is communicatively connected to the electrical control cabinet 4. This switch detects whether the lifting mechanism 2 is at the lower limit position. The electrical control cabinet 4 controls the energization of the traveling mechanism based on the lower limit position detection result. When the working platform 3 descends to its lowest point, triggering the lower limit switch 5, the electrical control cabinet 4 connects the traveling mechanism to the power supply. The traveling mechanism is then started by operating the corresponding start button. Otherwise, the traveling mechanism is disconnected from the power supply and cannot be started by operating the corresponding start button. This prevents the working platform 3 from remaining at a high position and activating the traveling mechanism, which could cause the wall-cutting platform to collapse due to excessive movement.

[0048] The frame 11 is equipped with outrigger switches 13 for detecting whether the leveling outriggers 12 are on the ground. These switches are communicatively connected to the electrical control cabinet 4. The electrical control cabinet 4 controls the hydraulic power system 24 of the lifting mechanism 2 based on the detection results of the outrigger switches 13. Specifically, each of the four leveling outriggers 12 is equipped with an outrigger switch 13. When the leveling outrigger 12 is on the ground and under force, the outrigger switch 13 is triggered, and the electrical control cabinet 4 controls the hydraulic power system 24 to connect to the power supply. Only when the hydraulic power system 24 operates can the lifting mechanism 2 function effectively and drive the work platform 3 to rise. This effectively prevents the work platform 3 from being raised or lowered without stable support, reducing the risk of equipment tipping over. Furthermore, the equipment uses the four leveling outriggers 12 for leveling, ensuring the overall machine's levelness is within 0.5 degrees before the lifting mechanism 2 can operate; otherwise, it cannot raise or lower.

[0049] See Figure 1The gantry 21 is also equipped with a protective limit switch 6, which communicates with the electrical control cabinet 4. This switch disconnects the power supply to the hydraulic power system 24 via the electrical control cabinet 4 when the bottom of the work platform 3 descends to 2 meters, thus stopping the descent of the lifting mechanism 2. In actual use, the work platform 3 stops descending when it reaches a height of 2 meters. The descent can only be restarted after pressing the corresponding descent button on the lifting mechanism 2 for 3 seconds. This allows the operator above to observe the situation below the work platform 3 and ensure there are no people or obstacles before proceeding with the descent, reducing the risk of personal injury or equipment damage.

[0050] The gantry 21 is also equipped with an upper limit switch 7, which is connected to the electrical control cabinet 4 to limit the upper limit position of the lifting mechanism 2.

[0051] See Figure 3 The hydraulic power system 24 is mounted on the frame 11 of the chassis 1 and includes an oil tank 241. The outlet end is connected to a main block valve 242, which is powered by a motor 245. The outlet end is connected to a flow divider valve 247, whose outlet ends are connected to hydraulic cylinders 23 installed in the side masts 21. The main block valve 242 is also equipped with a solenoid directional valve 243, which has an emergency pull rod 244. The emergency pull rod 244 is used to manually force the lifting mechanism 2 to descend in case of platform failure. Specifically, when the equipment malfunctions while in the raised state, the emergency pull rod 244 can be pulled to lower the working platform 3.

[0052] Furthermore, a pressure switch 246 is installed on the pipeline between the main block valve 242 and the diverter valve 247. The pressure switch 246 is communicatively connected to the electrical control cabinet 4 and is used to detect the pressure of the hydraulic power system 24. The electrical control cabinet 4 controls the working state of the motor 245 of the main block valve 242 according to the pressure. The electrical control cabinet 4 determines the load of the work platform 3 based on the pressure of the pressure switch 246. When the load of the work platform 3 exceeds the rated load, the electrical control cabinet 4 controls the motor 245 to disconnect from the power supply, preventing hydraulic oil from entering the hydraulic cylinder 23 through the main block valve 242. Therefore, the lifting mechanism 2 cannot drive the work platform 3 to achieve the lifting action. This avoids safety accidents caused by overloading the work platform 3 during lifting.

[0053] See Figure 1 The walking mechanism includes a drive wheel 14, a driven wheel 18, and a drive handle 15.

[0054] The drive wheel 14 is connected to the frame 11 of the chassis 1 and is located on one side of the gantry 21. It is driven by a drive motor. The drive motor is electrically connected to the electrical control cabinet 4, which is fixed on the frame 11 and located on one side of the gantry. A brake is connected to the control cabinet. Through the settings of the controller, the brake will automatically brake after the corresponding button is operated to prevent the equipment from sliding on the sloping ground and causing safety accidents such as personnel collisions and damage to property.

[0055] Driven wheel 18 is located below frame 11 of chassis 1 and works with drive wheel 14 to enable chassis 1 to move automatically on the ground.

[0056] The drive handle 15 is connected to the frame 11 of the chassis 1 via a horizontal support and is located above the drive wheel 14. It is equipped with a start / stop switch and an emergency stop switch for controlling the drive motor. A horizontal switch 17 is connected to the horizontal support. Operating the start / stop switch controls the drive motor to rotate the drive wheel 14, achieving automatic movement. Additionally, in case of an emergency during operation, the emergency stop switch can be pressed with both hands or the body to achieve emergency braking.

[0057] See Figure 2 Two movable maintenance support pipes 8 are placed on the frame 11 of the chassis 1 to support the lifting mechanism 2 and prevent the work platform 3 from falling during maintenance. When the work platform 3 is raised, the support pipes are installed below the lifting mechanism 2 to provide mechanical support for the gantry 21 and prevent the platform from falling, thus protecting the maintenance personnel below.

[0058] See Figure 2 The gantry 21 is also equipped with a hazard alarm flashing light 9, which is connected to the electrical control cabinet 4. During the ascent and descent of the work platform 3, the hazard alarm flashing light 9 will activate to emit an audible and visual alarm, serving as a warning function.

[0059] See Figure 2 The work platform 3 includes a cargo platform 31 and a guardrail gate.

[0060] The loading platform 31 is installed between the masts 21 on both sides of the lifting mechanism 2, and includes a main platform and a pedestrian platform arranged side by side. Specifically, the loading platform 31 is composed of a 3112mm*1192mm main platform and a 3000mm*400mm pedestrian platform. The entire platform is placed in the middle of the lifting mast 21. The interior of the platform is flat and free of any obstacles, providing ample space for personnel to move around and avoiding contact with other equipment and structural components outside the platform.

[0061] The guardrails are connected around the loading platform 31, including a fixed guardrail 32 fixed to the inside of the gantry 21, a side guardrail 33 inserted into one side of the fixed guardrail 32, and a loading guardrail gate 34 and a personnel guardrail gate 35 located on the opposite side of the side guardrail 33.

[0062] Specifically, the fixed guardrail 32 is bolted and cannot be removed unless necessary, isolating personnel from the lifting mechanism 2 to avoid personal injury from contact; the side guardrail 33 is plug-in connected, and the guardrail can be easily removed, facilitating personnel construction and freeing up more space; the loading guardrail gate 34 is a double-leaf gate, and the personnel guardrail gate 35 is a single-leaf gate. When loading materials, the loading guardrail gate 34 opens outward and is manually locked when closed; the personnel guardrail gate 35 opens inward when people are on it and automatically closes and locks after people have boarded.

[0063] See Figure 1 and 2 The lifting mechanism 2 also includes a chain drive assembly connecting the telescopic frame 22, and the telescopic frame 22 is equipped with a chain guard net on the side facing the work platform 3. This completely isolates the chain drive assembly from the operators on the work platform 3 to prevent accidents.
