Description

Technical Field

[0001] This utility model relates to the field of service platform technology, and in particular to an extended platform with a rotation function. Background Technology

[0002] In engineering fields such as tunnel excavation and mine roadway construction, the loading operation is a key link that determines the construction efficiency and blasting effect. As the core operating carrier for operators, the performance of the service platform directly affects the safety, efficiency and accuracy of the operation.

[0003] The traditional service platforms widely used in the industry are mainly divided into two categories: fixed-size and simple folding. However, they have shortcomings: fixed-size platforms usually do not have orientation adjustment functions. When it is necessary to carry out loading operations on the working face in different directions of the roadway, the entire platform needs to be moved or the operator needs to frequently change positions. This is not only cumbersome and time-consuming, but may also affect the accuracy of the operation due to collisions with the roadway wall during the movement of the platform, and may even bring safety hazards. Most simple folding platforms use simple hinge connections, which are not stable enough and have poor overall structural rigidity after unfolding. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing an extended platform with a rotation function. This effectively solves the problems that existing fixed-size platforms typically lack orientation adjustment capabilities, and that simple folding platforms often use simple hinge connections, resulting in insufficient support stability.

[0005] The technical solution adopted by this utility model to solve the above problems is as follows: An extended platform with slewing function includes a boom. A rotatable slewing bearing is installed at one end of the boom. A main station frame is installed on the upper end of the slewing bearing. Fixed frames are fixedly connected to both ends of the main station frame. A first traction rod and a second traction rod are coaxially rotatably connected to both ends of the fixed frames. A secondary station frame, which can be fixedly supported by the first traction rod, is rotatably installed at the other ends of the main station frame. A guardrail, which can be fixedly supported by the second traction rod, is rotatably connected to one end of the secondary station frame.

[0006] Preferably, a worm gear is fixedly connected to the slewing bearing, a motor is installed on the boom, and a worm is fixedly connected to the output end of the motor, with the worm meshing with the worm gear.

[0007] Preferably, a first pin is provided at the connection position between the first traction rod and the auxiliary station frame, and the first pin can be inserted and removed through the corresponding connection hole between the first traction rod and the auxiliary station frame.

[0008] Preferably, a second pin is provided at the connection position between the second traction rod and the guardrail, and the second pin can be inserted and pulled through the corresponding connection hole between the second traction rod and the guardrail.

[0009] Preferably, the two ends of the fixing frame are detachably equipped with buckles, and one end of the buckle is engaged with the auxiliary station frame.

[0010] Preferably, both the first and second traction rods are made of high-strength alloy steel, and the surfaces of both the first and second traction rods are galvanized for rust prevention.

[0011] Preferably, the upper surfaces of both the main station frame and the auxiliary station frame are covered with anti-slip mats, and the surface of the anti-slip mats is provided with raised anti-slip textures.

[0012] Preferably, a support plate is fixedly connected to the main station frame, and a canopy is installed on the support plate at the upper end of the main station frame.

[0013] Compared with the prior art, this utility model has the following advantages: 1. Through the structural design of the boom, rotatable slewing bearing, and worm gear transmission, the worm gear driven by the motor rotates synchronously, thereby enabling the main frame, auxiliary frame, and guardrail to rotate as a whole. Operators can flexibly adjust the platform's working direction by controlling the motor's start, stop, and forward / reverse rotation. Without moving the entire platform or frequently adjusting the position, it can quickly adapt to different working angle requirements, significantly improving the ease of operation in scenarios such as loading explosives, effectively reducing the time spent on orientation adjustments, and improving construction efficiency.

[0014] 2. Through the expansion structure of the main station frame, the rotatable auxiliary station frame, and the first traction rod support, the auxiliary station frame can be rotated around the main station frame to a horizontal state during operation. It is then fixed to the first traction rod by the first pin, which quickly expands the working area to meet the needs of multiple people working together or placing large tools. When storing, the auxiliary station frame can be flipped to fit against the main station frame, which greatly reduces the overall volume of the platform. It takes into account both a large working space and a small storage volume, solving the problem of insufficient space or inconvenient storage of fixed-size platforms. Attached Figure Description

Detailed Implementation

[0016] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0017] like Figures 1-4 As shown, an extended platform with a slewing function includes a boom 1. A rotatable slewing bearing 10 is installed at one end of the boom 1. A main station frame 4 is installed on the upper end of the slewing bearing 10. Fixed frames 3 are fixedly connected to both ends of the main station frame 4. A first traction rod 6 and a second traction rod 8 are coaxially rotatably connected to both ends of the fixed frame 3. A secondary station frame 5, which can be fixedly supported by the first traction rod 6, is rotatably installed at the other ends of the main station frame 4. A guardrail 7, which can be fixedly supported by the second traction rod 8, is rotatably connected to one end of the secondary station frame 5.

[0018] In use, the operator stands on the main frame 4 and manually pushes the two auxiliary frames 5 on both sides outward around their rotational connection with the main frame 4 until the auxiliary frames 5 and the main frame 4 are at the same level. Then, the first traction rods 6 at both ends of the fixing frame 3 are rotated so that the end of the first traction rod 6 away from the fixing frame 3 is aligned with the connection hole on the auxiliary frame 5, thus fixing the first traction rod 6 to the auxiliary frame 5 and completing the support and fixation of the auxiliary frame 5. At this time, the auxiliary frame 5 is stably unfolded and can be used as an extended working surface. During operation, the auxiliary frame 5 can be rotated around the main frame 4 to a horizontal state, and the position of the auxiliary frame 5 can be fixed by the first traction rod 6, quickly expanding the working area to meet the needs of multiple people working together or placing large tools. Next, push the guardrail 7 at one end of the auxiliary station frame 5 to rotate upward around its rotating connection with the auxiliary station frame 5 until the guardrail 7 is in a vertical state. Rotate the second traction rods 8 at both ends of the fixed frame 3 so that the end of the second traction rod 8 away from the fixed frame 3 is aligned with the connection hole on the guardrail 7. Use the second traction rods 8 to fix the position of the guardrail 7. After the guardrail 7 is unfolded, it can provide safety protection for the workers. When it is necessary to adjust the working direction of the platform, the slewing bearing 10 can be driven. When the slewing bearing 10 rotates, it will drive the main station frame 4 installed at the upper end, as well as the unfolded auxiliary station frame 5 and the guardrail 7 to rotate together. The operator can adjust the rotation angle and direction of the platform according to the actual working needs until the platform rotates to the appropriate working position.

[0019] A worm gear 11 is fixedly connected to the slewing bearing 10, and a motor 9 is installed on the boom 1. A worm 12 is fixedly connected to the output end of the motor 9, and the worm 12 meshes with the worm gear 11.

[0020] like Figure 4 As shown, the output end of motor 9 drives worm gear 12 to rotate, worm gear 12 drives worm wheel 11 to rotate, and worm wheel 11 drives slewing bearing 10 to rotate. The rotation angle and direction of the platform are adjusted by slewing bearing 10 until the platform rotates to the appropriate working position. Without moving the entire platform or frequently adjusting the position, it can quickly adapt to different working angle requirements, significantly improve the ease of operation in scenarios such as loading operations, effectively reduce the time spent on orientation adjustment, and improve construction efficiency.

[0021] A first pin 13 is provided at the connection position between the first traction rod 6 and the auxiliary station frame 5. The first pin 13 can be inserted and pulled through the corresponding connection hole between the first traction rod 6 and the auxiliary station frame 5.

[0022] like Figures 1-3 As shown, rotate the first traction rods 6 at both ends of the fixed frame 3 so that the end of the first traction rod 6 away from the fixed frame 3 is aligned with the connecting hole on the auxiliary station frame 5. Insert the first pin 13 into the aligned connecting hole to fix the first traction rod 6 to the auxiliary station frame 5, thereby completing the support and fixation of the auxiliary station frame 5. At this time, the auxiliary station frame 5 is stably unfolded and can be used as an extended working surface. During operation, the auxiliary station frame 5 can be rotated around the main station frame 4 to a horizontal state and fixed to the first traction rod 6 by the first pin 13, which can quickly expand the working area and meet the needs of multiple people working together or placing large tools.

[0023] A second pin 14 is provided at the connection position between the second traction rod 8 and the guardrail 7. The second pin 14 can be inserted and pulled through the corresponding connection hole between the second traction rod 8 and the guardrail 7.

[0024] like Figures 1-3 As shown, the guardrail 7 at one end of the auxiliary station frame 5 rotates upward around its rotatable connection with the auxiliary station frame 5 until the guardrail 7 is in a vertical state. Rotate the second traction rods 8 at both ends of the fixing frame 3 so that the end of the second traction rod 8 away from the fixing frame 3 is aligned with the connection hole on the guardrail 7. Insert the second pin 14 into the aligned connection hole to complete the fixation of the second traction rod 8 and the guardrail 7. After the guardrail 7 is unfolded, it can provide safety protection for the workers.

[0025] Both ends of the fixed frame 3 are detachably equipped with buckle rods 16, one end of which is engaged with the auxiliary station frame 5.

[0026] like Figure 3As shown, the buckle rods 16 installed at both ends of the fixed frame 3 are inserted into the pivot rods of the guardrail 7 and the auxiliary station frame 5, so that the auxiliary station frame 5 and the guardrail 7 are attached to both ends of the main station frame 4, thereby ensuring that all components are in a retracted and stored state, reducing the space occupied by the platform, and facilitating subsequent transportation or storage. When storing, the auxiliary station frame 5 can be flipped to fit against the main station frame 4, greatly reducing the overall volume of the platform and effectively solving the problem of inconvenient storage.

[0027] Both the first traction rod 6 and the second traction rod 8 are made of high-strength alloy steel, and the surfaces of both the first traction rod 6 and the second traction rod 8 are galvanized for rust prevention.

[0028] like Figure 1 and 2 As shown, the first traction rod 6 and the second traction rod 8 are made of high-strength alloy steel and have been galvanized for rust prevention. They have sufficient support strength to withstand the weight of operators and tools and prevent deformation and breakage of the support components. They can also resist dust and moisture corrosion in tunnels, mines and other environments, extend the service life of the components, ensure the structural stability of the platform during long-term use, and reduce safety hazards caused by component damage.

[0029] The upper surfaces of both the main station frame 4 and the auxiliary station frame 5 are covered with anti-slip mats, and the anti-slip mats have raised anti-slip textures on their surfaces.

[0030] like Figure 1 and 2 As shown, the upper surfaces of both the main station frame 4 and the auxiliary station frame 5 are covered with anti-slip mats with raised anti-slip textures, which can increase the friction between the operator's shoes and the platform surface. Even in harsh environments such as damp tunnels and dust, it can effectively prevent operators from slipping and ensure the personal safety of the workers.

[0031] A support plate 15 is fixedly connected to the main station frame 4, and a canopy 2 is installed on the support plate 15 at the upper end of the main station frame 4.

[0032] like Figure 1 As shown, the support plate 15 provides support and fixation for the canopy 2, and the canopy 2 can be used to protect the staff on the main station frame 4.

[0033] The working process of this utility model is as follows: The operator stands on the main frame 4 and manually pushes the two auxiliary frames 5 on both sides to rotate outward around the rotational connection between them and the main frame 4 until the auxiliary frames 5 and the main frame 4 are at the same level. Then, the first traction rods 6 at both ends of the fixed frame 3 are rotated so that the end of the first traction rod 6 away from the fixed frame 3 is aligned with the connection hole on the auxiliary frame 5. The first pin 13 is inserted into the aligned connection hole to fix the first traction rod 6 to the auxiliary frame 5, thereby completing the support and fixation of the auxiliary frame 5. At this time, the auxiliary frame 5 is stably unfolded and can be used as an extended working surface. During operation, the auxiliary frame 5 can be rotated around the main frame 4 to a horizontal state and fixed with the first traction rod 6 by the first pin 13, which can quickly expand the working area and meet the needs of multiple people working together or placing large tools.

[0034] Next, push the guardrail 7 at one end of the auxiliary station frame 5 to rotate upward around its rotating connection with the auxiliary station frame 5 until the guardrail 7 is in a vertical state. Rotate the second traction rods 8 at both ends of the fixing frame 3 so that the end of the second traction rod 8 away from the fixing frame 3 is aligned with the connection hole on the guardrail 7. Insert the second pin 14 into the aligned connection hole to complete the fixing of the second traction rod 8 and the guardrail 7. After the guardrail 7 is unfolded, it can provide safety protection for the workers.

[0035] When the platform's operating direction needs to be adjusted, the operator starts motor 9, energizing it. The output of motor 9 drives the worm gear 12 to rotate. Since the worm gear 12 meshes with the worm wheel 11 fixedly connected to the slewing bearing 10, the rotation of the worm gear 12 drives the worm wheel 11 to rotate synchronously, thereby causing the slewing bearing 10 to rotate around its own axis. When the slewing bearing 10 rotates, it drives the main station frame 4 installed at the upper end, as well as the deployed auxiliary station frame 5 and guardrail 7, to rotate together. The operator adjusts the platform's rotation angle and direction by controlling the start and stop of motor 9 according to actual operational needs, until the platform rotates. Once the platform reaches the appropriate working position, motor 9 is turned off, and the slewing bearing 10 stops rotating. The platform remains in the current working direction. Motor 9 drives the worm gear 12 to rotate, which in turn drives the worm wheel 11, which is fixed to the slewing bearing 10, to rotate synchronously. This achieves the overall rotation of the main platform 4, the auxiliary platform 5, and the guardrail 7. Operators can flexibly adjust the platform's working direction by controlling the start, stop, forward, and reverse rotation of motor 9. This allows for quick adaptation to different working angle requirements without moving the entire platform or frequently adjusting the position, significantly improving the ease of operation in scenarios such as loading explosives, effectively reducing the time spent on orientation adjustments, and improving construction efficiency.

[0036] After the operation is completed, pull out the second pin 14 to release the fixation between the second traction rod 8 and the guardrail 7. Manually flip the guardrail 7 downward around its rotating connection with the auxiliary station frame 5 so that the guardrail 7 fits against the auxiliary station frame 5. This can be used as a ladder to facilitate climbing down the main station frame 4. Then pull out the first pin 13 to release the fixation between the first traction rod 6 and the auxiliary station frame 5. Push the auxiliary station frame 5 to flip inward around its rotating connection with the main station frame 4 so that the auxiliary station frame 5 fits against the main station frame 4.

[0037] The buckle rods 16 installed at both ends of the fixed frame 3 are inserted into the pivot rods of the guardrail 7 and the auxiliary station frame 5, so that the auxiliary station frame 5 and the guardrail 7 are attached to both ends of the main station frame 4, thereby ensuring that all components are in a retracted and stored state, reducing the space occupied by the platform and facilitating subsequent transportation or storage. When storing, the auxiliary station frame 5 can be flipped to fit against the main station frame 4, greatly reducing the overall volume of the platform and effectively solving the problem of inconvenient storage.
