Description

Technical Field

[0001] This invention relates to a construction device, specifically a single-tube iron tower construction device. Background Technology

[0002] The advantages of single-tube towers are: simple and reasonable structure; beautiful appearance; and convenient installation and use. They also occupy less space compared to angle steel towers. However, single-tube towers are relatively tall, requiring large cranes for installation, resulting in higher installation costs and a larger construction site. They are also inconvenient to operate in confined spaces. Furthermore, since some steel pipe towers require welding, workers need to be lifted to the appropriate height using suspended platforms or other climbing equipment, and then welded or installed with the assistance of a crane. Slight carelessness could lead to falls and injuries, causing safety accidents. Summary of the Invention

[0003] To address the problems existing in the prior art, this invention provides a single-tube tower construction device that eliminates the need for a crane, reducing the installation cost of single-tube towers while providing workers with a stable working platform and effectively improving worker safety.

[0004] To achieve the above objectives, the present invention provides a single-tube tower construction device, comprising a main frame, a frame, a pressure platform, a work platform mounting base, a lifting drive telescopic arm, a safety device, a safety device shaft, a pressure hydraulic rod, a main braking hydraulic rod, a pipe clamping plate, a work platform, railings, a station plate, a lifting drive device, a single-tube up-and-down drive box, a transformer, a drive motor, a reducer, a limit slide rail for the single-tube up-and-down drive box, a single-tube tower clamping plate, a drive wheel, auxiliary ball bearings, a cable frame, a single-tube hoisting rail, a trolley, a winch, a footboard, and a control cabinet. Two symmetrically arranged main frames are interconnected by reinforcing components and angle steel to form a core support structure. A single-tube hoisting rail is fixedly installed on the upper part of the two main frames via supports, and the single-tube hoisting rail extends to one side between the two frames. A cable frame is fixedly installed on the top of the two main frames, and the cable frame is connected to the far end of the single-tube hoisting rail extension section via steel wire ropes. The trolley moves back and forth on the single-tube hoisting rail, and a winch is installed under the trolley. A work platform is welded and installed in the middle of the frame. The platform is mounted on a U-shaped mounting base. A foldable step is installed at the U-shaped opening of the platform. The single-tube overhead rail extension is directly above the step. A lifting drive device is mounted on the lower part of the platform mounting base via a telescopic arm. The lifting drive devices on the two frames are symmetrically arranged. A pressure platform is welded to the frame above the platform mounting base. A safety device is installed above the pressure platform and connected to the pressure platform via a safety device shaft. One end of the main brake hydraulic rod is hinged to a pipe gripping plate, and the other end is fixedly connected to the safety device shaft. The two ends of the pressure hydraulic rod are respectively hinged to the pressure platform and the main brake hydraulic rod. When moving upward, the two pipe gripping plates tightly press against the single tube, and the main brake hydraulic rod, under the action of the pressure hydraulic rod, allows the pipe gripping plates to exert force in an inclined manner. Therefore, when the lifting drive device drives the equipment to rise, the single tube can slide downward. And if the lifting drive device fails and causes the equipment to suddenly drop, it can stop in time.

[0005] The control cabinet is mounted on the outside of the core support at the same height as the work platform via a bracket.

[0006] As a further improvement of the present invention, the lifting drive device includes a single-tube up-and-down drive box, a single-tube up-and-down drive box limiting slide rail, a single-tube tower clamping plate, a drive wheel, and auxiliary balls. The single-tube up-and-down drive box has a single-tube tower clamping plate installed on the side facing the main frame. A drive wheel is located in the middle of the single-tube tower clamping plate, and auxiliary balls are located on both sides. The two sides of the single-tube up-and-down drive box are connected to the main frame via the single-tube up-and-down drive box limiting slide rail. During movement, the single-tube tower clamping plates on both sides clamp the single tube, ensuring that the device can stably exist on the single tube, and the drive wheel enables the device to perform lifting operations.

[0007] As a further improvement of the present invention, the single-tube up-and-down drive box includes a transformer, a drive motor and a reducer. The single-tube up-and-down drive box has a built-in transformer, a drive motor and a reducer. The transformer is electrically connected to the drive motor, and the power of the drive motor is transmitted to the drive wheel through the reducer.

[0008] As a further improvement of the present invention, the working platform includes railings and a platform, with cylindrical railings mounted on the upper part of the platform via a bracket with reinforcing members.

[0009] As a further improvement of the present invention, a protective railing is installed on the upper surface of the pedal via a bracket.

[0010] As a further improvement of the present invention, the railing is cylindrical and has a diameter of no more than four centimeters.

[0011] As a further improvement of the present invention, the working platform is equipped with a safety descent rope.

[0012] By means of the above solution, the present invention has at least the following advantages: after using this equipment, the installation of single-tube iron towers does not require the arrival of a crane, which can greatly reduce the area required for construction, effectively control the installation cost of single-tube towers, and provide a stable working platform so that workers can carry out single-tube installation work in a more stable state.

[0021] The single-tube tower construction device of the present invention will now be described with reference to the accompanying drawings.

[0022] In the first specific embodiment of this application, as Figures 1 to 3 and Figure 5As shown, this single-tube tower construction device consists of two symmetrically arranged main frames 1 connected by reinforcing components and angle steel to form a core support. This core support serves as the core of the entire device, fixing all peripheral equipment and ensuring that these devices maintain their center of gravity on the steel pipe tower, preventing lateral tilting forces. The entire core support also features a large-area openwork design to prevent sudden strong winds from causing safety hazards during construction. A single-tube suspension rail 6 is fixedly installed on the upper part of the frame 1-1 of the two main frames 1 via supports, extending to one side between the two frames 1-1. A cable frame 5 is fixedly installed on the top of the frame 1-1 of the two main frames 1, connecting the cable frame 5 to the far end of the extended section of the single-tube suspension rail 6 via steel wire ropes. A trolley 7 moves back and forth on the single-tube suspension rail 6. A winch 8 is located below the trolley 7, which, with the assistance of the trolley 7, can lift the section of steel pipe to be installed into the core support, making it easier to align with the already installed steel pipe and facilitating subsequent construction work. A work platform mounting base 1-3 is welded and installed in the middle of frame 1-1. A U-shaped work platform 3 is fixedly installed on the work platform mounting base 1-3. A foldable step 9 is installed at the U-shaped opening of the work platform 3. Above the step 9 is the extension section of the single-tube suspension rail 6. Workers can perform assembly and welding operations around the single-tube iron tower on the work platform 3, providing a stable working environment. A lifting drive device 4 is installed at the lower part of the work platform mounting base 1-3 via a telescopic arm 1-4. The lifting drive devices 4 installed on the two frames 1-1 are symmetrically arranged. This symmetrical arrangement allows the two sets of lifting drive devices 4 to tightly clamp the single-tube iron tower, thus providing sufficient friction for the drive wheels 4-4, facilitating the lifting of the equipment. The frame 1-1 above the work platform mounting base 1-3 is welded and pressurized. Platform 1-2, with a safety device 2 above it. The safety device 2 is connected to the pressure platform 1-2 via a safety device pivot 2-1. One end of the main braking hydraulic rod 2-3 is hinged to a pipe-holding plate 2-4, and the other end is fixedly connected to the safety device pivot 2-1. The two ends of the pressure hydraulic rod 2-2 are respectively hinged to the pressure platform 1-2 and the main braking hydraulic rod 2-3. When moving upward, the two pipe-holding plates 2-4 tightly press against the single pipe, and the main braking hydraulic rod 2-3, under the action of the pressure hydraulic rod 2-2, allows the pipe-holding plates 2-4 to exert force in an inclined manner. Therefore, when the lifting drive device 4 drives the equipment to rise, the single pipe can slide downward. When the lifting drive device 4 fails and the equipment suddenly falls, the pipe-holding plates 2-4 can be firmly pressed against the surface of the single pipe under the action of the pressure hydraulic rod 2-2 and the main braking hydraulic rod 2-3, thereby enabling the equipment to stop in time and prevent it from falling. The control cabinet 10 is mounted on the outside of the core support at the same height as the work platform 3 via a bracket. The control cabinet 10 has a built-in microcontroller, which greatly simplifies the operation of the equipment and reduces the labor intensity of workers.

[0023] like Figure 6As shown, in order to enable the lifting drive device 4 to better drive its overall lifting, as a further improvement of the present invention, the lifting drive device 4 includes a single-tube up-and-down drive box 4-1, a single-tube up-and-down drive box limiting slide rail 4-2, a single-tube tower clamping plate 4-3, a drive wheel 4-4, and auxiliary balls 4-5. The single-tube up-and-down drive box 4-1 is equipped with the single-tube tower clamping plate 4-3 on the side facing the main frame 1. The single-tube tower clamping plate 4-3 has a drive wheel 4-4 in the middle and auxiliary balls 4-5 on both sides. The moving box 4-1 is connected to the main frame 1 on both sides by single-tube upper and lower drive box limit slide rails 4-2. The single-tube upper and lower drive box limit slide rails 4-2 on both sides of the single-tube upper and lower drive box 4-1 can help the single-tube upper and lower drive box 4-1 open and close more stably in the core support, preventing its own weight from damaging the telescopic arm 1-4 of the lifting drive device. When moving, the single-tube iron tower clamps 4-3 on both sides form a clamping posture on the single tube, ensuring that the equipment can be stably placed on the single tube, and the equipment can be lifted and lowered with the help of the drive wheels 4-4.

[0024] like Figure 7 As shown, in order to provide maximum torque, as a further improvement of the present invention, the single-tube up-and-down drive box 4-1 includes a transformer 4-1-1, a drive motor 4-1-2, and a reducer 4-1-3. The single-tube up-and-down drive box 4-1 houses the transformer 4-1-1, the drive motor 4-1-2, and the reducer 4-1-3. The transformer 4-1-1 is electrically connected to the drive motor 4-1-2. The power of the drive motor 4-1-2 is transmitted to the drive wheel 4-4 through the reducer 4-1-3. Although a low-speed motor can be used to directly connect to the drive wheel 4-4, a low-speed motor alone is very likely to cause insufficient torque. Therefore, in order to amplify the torque, a reducer 4-1-3 is needed between the drive motor 4-1-2 and the drive wheel 4-4.

[0025] like Figure 4 As shown, in order to provide a place for the safety rope of the workers to be connected and to provide certain safety protection for the workers, as a further improvement of the present invention, the work platform 3 includes a railing 3-1 and a platform 3-2. The cylindrical railing 3-1 is installed on the upper part of the platform 3-2 through a bracket with reinforcement.

[0026] To further facilitate the connection of safety ropes and provide safety protection for workers, as a further improvement of the present invention, a guardrail is installed on the upper surface of the platform 9 via a bracket. To facilitate the connection of various joints of the safety rope using the guardrail 3-1, as a further improvement of the present invention, the guardrail 3-1 is cylindrical with a diameter not exceeding four centimeters. To ensure timely evacuation of personnel in the event of a sudden equipment malfunction, as a further improvement of the present invention, the work platform 3 is equipped with a safety descent rope.

[0027] When in use, the single-tube tower construction device is installed and connected to the corresponding pipelines, and the equipment can then be put into operation.

[0028] When in use, this invention works as follows:

[0029] Step 1: Transport the main frame 1, safety device 2, work platform 3, lifting drive device 4, cable rack 5, single-tube suspension rail 6, trolley 7, winch 8, pedal 9, and control cabinet 10 to the construction site by truck and assemble them. Step 2: Pour the foundation of the single-tube electric tower, and use a small crane or the crane on the truck to install the first section of the single-tube tower onto the base. After connecting the corresponding pipelines to this device, lift the device, align the core support with the first section of the single tube, and slowly lower it until the top of the first section of the single tube is higher than the safety device 2. Step 3: Control the extension arm 1-4 of the lifting drive device to retract, so that the lifting drive device 4 clamps the first section of the single tube. Step 4: Control the extension of the pressurizing hydraulic rod 2-2, and lift the main braking hydraulic rod 2-3 so that it changes its angle around the safety device pivot 2-1, and finally makes the pipe clamp 2-4 abut against the single tube wall. Step 5: Construction begins. The crane 7 moves to the end of the extension section of the single-tube hanging rail 6, transports the next-level single tube to below the winch 8, and the winch 8 lowers its hook to hold the top of the next-level single tube. Then, the single tube is lifted to the upper part of the frame 1-1. The crane 7 then moves the winch 8, which has been hoisted with the single tube, to directly above the first single tube section. After aligning with the single tube, welding can begin. Step 6: The drive motor 4-1-2 of the lifting drive device 4 drives the drive wheel 4-4 through the reducer 4-1-3, causing the entire equipment to move upward. Once the equipment has moved to the newly installed single tube, steps 5 and 6 can be repeated.

Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
