Description

Technical Field

[0001] This invention relates to the field of fire protection engineering technology, and in particular to a safety protection device for the maintenance of fire protection equipment. Background Technology

[0002] After prolonged use, fire protection facilities inevitably experience a decline in effectiveness due to material properties and daily handling, affecting their overall usability and failing to meet original usage requirements. Therefore, specialized maintenance is necessary. However, some electromechanical equipment is installed in remote locations to mitigate fire hazards, making it difficult to maintain with common repair equipment. This also carries risks of falling parts and electrical leaks. Currently available equipment often lacks adequate protective structures, and operators lack auxiliary lifting equipment, requiring direct contact with hazardous areas. This fails to adequately reduce overall maintenance risks and thus cannot meet current practical usage needs. Summary of the Invention

[0003] The purpose of this invention is to provide a safety protection device for fire equipment maintenance, which solves the technical problems of lack of relevant supporting auxiliary equipment, inconvenience in structural installation, and poor protective effect in the prior art. It achieves the technical effect of fully assisting structural installation operations, improving overall installation efficiency, and improving overall protective effect.

[0004] To achieve the above-mentioned objectives, the technical solution adopted by this invention is as follows:

[0005] A safety protection device for fire equipment maintenance includes a vehicle body, a work platform, and a lifting arm. Wheels are rotatably connected to both sides of the lower end of the vehicle body, and the wheels are driven by a motor inside the vehicle body. Diagonal bracing structures are fixed to both sides of the vehicle body near the wheels, and guard plates are fixed to the lower ends of the diagonal bracing structures for diagonal support and positional fixation of the vehicle body. The work platform is located above the vehicle body and is connected via a scissor lift. A lifting motor is located at the connection point between the lower end of the scissor lift and the vehicle body. One end of the lifting motor is driven by a push rod, which is connected to the bottom side of the scissor lift. The sliding block connection at the end is used to raise and lower the height of the worktable. A protective canopy is provided above the worktable, and a folding frame is provided below the protective canopy. The folding frame is located on both sides of the worktable, and its upper end is slidably connected to the protective canopy through a pulley limiting structure. A folding motor is provided at the lower end of the folding frame, and a lead screw is connected to the rotating shaft of the folding motor. One end of the lead screw is threadedly connected to the slider at the lower end of the folding frame to control the unfolding and folding of the folding frame. The lifting arm is located at the upper end of the vehicle body and on one side of the scissor lift. The lifting arm is used to assist the hoisting equipment in non-contact construction.

[0006] As an improvement, a battery pack is fixed inside the vehicle body, located between the wheels, for supplying power to the motor. A control panel is fixed on one side of the vehicle body, and a control module is fixed inside the control panel for transmitting control commands to the electrical components. A charging port is provided below the control panel, and one end of the charging port has a protection module for charging the battery inside the vehicle body.

[0007] As an improvement, there are four sets of diagonal bracing structures on both sides of the vehicle body, symmetrically designed with the vehicle body axis as the reference. Each diagonal bracing structure includes an electric push rod and a guide seat. The electric push rod is inclined at 30° away from the wheel. A movable rod is fitted inside the guide seat and is arranged parallel to the electric push rod. The upper end of the guard plate has a connecting plate that connects to the electric push rod and the movable rod for supporting diagonal movement. The lower end of the guard plate has anti-slip texture to increase friction with the ground and improve the overall support effect.

[0008] As an improvement, a bottom support structure is fixed to the lower end of the vehicle body. The bottom support structure is located between the wheels and in the middle of the vehicle body. The upper end of the bottom support structure is equipped with an electric push rod connected to the vehicle body. The bottom support structure is a rectangular frame used to cooperate with the electric push rod to provide bottom plane support. A ground wire connector is fixed to one side of the bottom support structure. The upper and lower ends of the ground wire connector have interfaces for connecting the ground wire to protect the internal electrical structure.

[0009] As an improvement, a loading ladder is fixed to one side of the vehicle body, which is located directly below the workbench. The workbench has a door panel on one side, and a suspended ladder extends from the lower end of the door panel. The suspended ladder is positioned opposite the loading ladder to facilitate personnel getting on and off when the scissor lift is folded and stored. A control console is fixed to the side of the workbench near the lifting arm, and the upper end of the control console has control buttons for controlling the start-up and operation of various electrical devices.

[0010] As an improvement, the protective canopy is made of engineering plastic with a rounded surface. Metal mounting frames are fixed on both sides of the protective canopy. One side and the bottom of the mounting frame are respectively equipped with a sliding groove and a sliding rail. The pulley limiting structure includes two sets of pulleys and one set of limiting pulleys. The pulleys are arranged side by side, and one side of them cooperates with the sliding rail to achieve directional sliding. The limiting pulleys, in conjunction with the connecting rod, extend to the sliding groove, and their wheel structure is located inside the sliding groove to limit the lateral movement of the entire pulley limiting structure. The two ends of the mounting frame are equipped with spring rods, which are set towards the pulley limiting structure to limit the lateral movement distance of the pulley limiting structure.

[0011] As an improvement, the lower end of the lifting arm is rotatably connected to a rotating seat, and a rotating motor is fixed inside the rotating seat. The rotating shaft of the rotating motor is driven by a rotating seat that is rotatably connected to the vehicle body for adjusting the position of the lifting arm. An adjusting support arm is fixed inside the lifting arm. The adjusting support arm is movably sleeved with the lifting arm through a hydraulic push rod. A cable is wound inside the adjusting support arm, and one end of the cable has a hook. A winding frame is located on the side of the lifting arm away from the rotating seat. The winding frame works with the cable to lift and suspend the hook.

[0012] The beneficial effects of this invention are as follows: the vehicle body facilitates the movement and transfer of the entire equipment; the inclined and bottom support structures adapt to different ground conditions to achieve sufficient and stable support; personnel can easily climb onto the work platform for high-altitude operations; the folding frame and protective canopy effectively prevent falling objects; the pulley limiting structure provides sufficient shock absorption and allows larger debris to slide off along the sides of the protective canopy, further reducing overall damage; the lifting arm assists workers on the work platform in hoisting other structures and provides stable support for the maintenance equipment; operators only need to directly contact and maintain specific locations, improving overall safety and maintenance efficiency.

[0017] To make the content of this invention easier to understand, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Identical components are represented by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0018] like Figures 1 to 3 As shown, a safety protection device for fire equipment maintenance includes a vehicle body 1, a work platform 12, and a lifting arm 18. Wheels 4 are rotatably connected to both sides of the lower end of the vehicle body 1. The wheels 4 are driven by a motor inside the vehicle body 1. Diagonal bracing structures 2 are fixed to both sides of the vehicle body 1 near the wheels 4. A guard plate 3 is fixed to the lower end of the diagonal bracing structure 2 for diagonally supporting the vehicle body 1 and fixing its position. The work platform 12 is located above the vehicle body 1 and is connected via a scissor lift 11. A lifting motor 10 is located at the connection point between the lower end of the scissor lift 11 and the vehicle body 1. One end of the lifting motor 10 is driven by a push rod, which is connected to the bottom side of one side of the scissor lift 11. A sliding block connection is used to raise and lower the height of the work platform 12. A protective canopy 15 is provided above the work platform 12, and a folding frame 14 is provided below the protective canopy 15. The folding frame 14 is located on both sides of the work platform 12, and its upper end is slidably connected to the protective canopy 15 through a pulley limiting structure 19. A folding motor 13 is provided at the lower end of the folding frame 14. The rotating shaft of the folding motor 13 is connected to a lead screw. One end of the lead screw is threadedly connected to the slider at the lower end of the folding frame 14 to control the unfolding and folding of the folding frame 14. A lifting arm 18 is located at the upper end of the vehicle body 1 and on one side of the scissor lift 11. The lifting arm 18 is used to assist the hoisting equipment in non-contact construction. Warning lights are provided on both sides of the vehicle body 1 to illuminate the area around the vehicle body 1 and provide warning. The bottom of the vehicle body 1 has multiple sets of counterweight structures, which are detachably connected through a mounting bracket to adjust the center of gravity of the vehicle body 1 for convenient high-altitude operations.

[0019] A battery pack is fixed inside the vehicle body 1, located between the wheels 4, and is used to power the motor. A control panel 9 is fixed to one side of the vehicle body 1, and a control module is fixed inside the control panel 9 for transmitting control commands to the electrical components. A charging port 8 is located below the control panel 9, and one end of the charging port 8 has a protection module for charging the battery inside the vehicle body 1. An antenna is located on one side of the control panel 9, which can remotely transmit and receive corresponding control signals and operating data status, thereby facilitating remote monitoring or control.

[0020] In use, the operator can control the movement of the vehicle body 1 using the remote control and control panel 9. Once it reaches the designated working position, the corresponding diagonal bracing structure 2 is activated, ensuring the protective plate 3 makes full contact with the ground and supports and secures the entire vehicle body 1. At this point, the operator can activate the folding motor 13 via the control panel 9 to unfold the protective canopy. After the operator climbs onto the work platform 12, they can control the lifting motor 10 to raise the scissor lift 11, thus raising the height of the work platform 12. At this time, the operator can activate the lifting arm 18 to hoist other related accessories for assistance during installation, improving the overall installation effect while reducing direct operator intervention and ensuring operational safety.

[0021] However, during use, the operation of the relevant motors during the lifting and lowering of the worktable 12 and the raising of the lifting arm 18 will generate corresponding vibrations, which may cause the equipment to be not securely fixed and may lead to the risk of tipping over. In order to effectively ensure the overall stability of the equipment, the following improvements have been made:

[0022] There are four sets of diagonal bracing structures 2 on both sides of the vehicle body 1, symmetrically designed with the axis of the vehicle body 1 as the reference. Each diagonal bracing structure 2 includes an electric push rod and a guide seat. The electric push rod is inclined at 30° away from the wheel 4. A movable rod is fitted inside the guide seat and is arranged parallel to the electric push rod. The upper end of the guard plate 3 has a connecting plate that connects to the electric push rod and the movable rod for diagonal movement support. The lower end of the guard plate 3 has anti-slip texture to increase friction with the ground and improve the overall support effect. A bottom support structure 6 is fixed to the lower end of the vehicle body 1. The bottom support structure 6 is located between the wheels 4 and in the middle of the vehicle body 1. The upper end of the bottom support structure 6 has an electric push rod connected to the vehicle body 1. The bottom support structure 6 is a rectangular frame used to provide bottom plane support in conjunction with the electric push rod. A ground wire connector 7 is fixed to one side of the bottom support structure 6. The upper and lower ends of the ground wire connector 7 have interfaces for connecting the ground wire to protect the internal electrical structure. A loading ladder 5 is fixed to one side of the vehicle body 1, located directly below the workbench 12. The workbench 12 has a door panel on one side, with a suspended ladder extending from its lower end. This suspended ladder is positioned opposite the loading ladder 5 to facilitate personnel access when the scissor lift 11 is folded and stored. A control console 16 is fixed to the side of the workbench 12 near the lifting arm 18. The control console 16 has control buttons on its upper end for controlling the start-up and operation of various electrical devices. Different types of anti-slip pads can be added to the lower end of the base support structure 6 according to usage requirements to adapt to different ground conditions and achieve better stability.

[0023] When in use, the diagonal bracing structure 2 and the bottom bracing structure 6 will fully conform to the ground to achieve stable support. They can also be used in conjunction with other counterweight structures to press down on the frame of the bottom bracing structure 6 to further improve the support effect.

[0024] When in use, the protective canopy 15 will vibrate when impacted by falling objects, which will significantly affect the connection structure between the folding frames 14, easily causing structural deformation and loss of the original folding effect, thus reducing the protective effect. In order to further improve the performance of the protective canopy, the following improvements are made:

[0025] The protective canopy 15 is made of engineering plastic with a rounded surface. Metal mounting frames are fixed to both sides of the canopy 15. Each mounting frame has a groove and a rail on one side and at the bottom, respectively. The pulley limiting structure 19 includes two sets of pulleys and one set of limiting pulleys. The pulleys are arranged side-by-side, with one side working in conjunction with the rail for directional sliding. The limiting pulleys extend to the groove with a connecting rod, and their wheel structure is located inside the groove to limit the lateral movement of the entire pulley limiting structure 19. Spring rods are located at both ends of the mounting frame, facing the pulley limiting structure 19 to limit its lateral movement. The protective canopy 15 has multiple sets of reinforcing ribs inside. These ribs can slightly deform with the engineering plastic to absorb the impact of falling objects. If a large object falls on the protective canopy 15, the pulley limiting structure 19 will move to both sides of the workbench 12, thereby causing the protective canopy 15 to tilt, thus converting the impact force into an oblique force and guiding it away, reducing the damage caused by the impact. At the same time, it can automatically reset in conjunction with the spring rod structure, which is convenient for subsequent use.

[0026] The lower end of the lifting arm 18 is rotatably connected to a rotating seat 17. A rotating motor is fixed inside the rotating seat 17. The rotating shaft of the rotating motor is driven by a rotating base that is rotatably connected to the vehicle body 1, used to adjust the position of the lifting arm 18. An adjusting support arm is fixed inside the lifting arm 18. The adjusting support arm is movably sleeved with the lifting arm 18 via a hydraulic push rod. A cable is wound inside the adjusting support arm, and one end of the cable has a hook. A winding frame is located on the side of the lifting arm 18 away from the rotating seat 17. The winding frame, in conjunction with the cable, enables the hook to be lifted. The upper end of the adjusting support arm has a mounting plate. The inner side of the mounting plate has multiple sets of limiting holes, which can be used with bolts to install various accessories, providing support for the maintenance of different instruments.

[0027] When in use, the operator can start the rotating seat 17 through the control button on the workbench 12, so that the lifting arm 18 moves to the corresponding working position. Then, the operator can control the winding frame to work with the hook to lift part of the heavy object to the corresponding installation height, so as to realize the installation and maintenance of the equipment, reduce the direct contact of the operator, and thus improve the overall protection effect.

[0028] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
