Description

Technical Field

[0001] This application relates to the technical field of cranes, and in particular to a crane rail that is easy to assemble and disassemble. Background Technology

[0002] Double-girder bridge cranes are a common type of heavy-duty lifting equipment. They consist of two parallel beams supporting a movable boom and the load. These cranes are commonly used in various industrial sectors, such as manufacturing, construction, and logistics. As mechanical equipment, double-girder bridge cranes are prone to malfunctions. To ensure maintenance personnel can access the elevated crane platform for repairs, these cranes are designed to withstand such failures.

[0003] However, the existing track maintenance platform is not easy to disassemble. Due to the structural characteristics and installation method of the crane track maintenance platform, as well as the limitations of space and environment, the disassembly process often takes a long time. This will lead to the crane downtime, affect the production progress, and cause certain economic losses to the enterprise. In addition, although the existing maintenance platform is equipped with a fence for protection, the height of the fence cannot be adjusted because the height of the workers is different, which sometimes still poses a certain risk. Summary of the Invention

[0004] To facilitate the disassembly and assembly of the rail maintenance platform and to make it easier for workers to use, this application provides a crane rail maintenance platform that is easy to disassemble and assemble.

[0005] The crane rail maintenance platform that is easy to assemble and disassemble provided in this application adopts the following technical solution:

[0006] A crane rail maintenance platform that is easy to assemble and disassemble includes two slide rail bridges. A safety bar is fixedly installed on one side of the top of each slide rail bridge. A bridge crane is slidably installed on the top between the two slide rail bridges. Sliding components are fixedly installed on the outer sides of each of the two slide rail bridges. A transmission component is installed inside each sliding component. An installation component for connection and disassembly is fixedly installed on one side of each sliding component. A platform component is fixedly installed inside one of the installation components. A safety protection component is fixedly installed on the top of the platform component.

[0007] Preferably, the sliding assembly includes four sliding brackets, two of which are fixedly installed on one side of a slide rail bridge, and the other two are fixedly installed on one side of another slide rail bridge. Each of the four sliding brackets has two sliding blocks slidably installed inside, allowing continuous movement along the track. This eliminates the need for frequent setup and dismantling of temporary maintenance facilities as in traditional maintenance methods, greatly saving maintenance preparation time and allowing maintenance personnel to focus on the maintenance work itself, thereby improving overall maintenance efficiency.

[0008] Preferably, the transmission assembly includes two lead screws, which are rotatably installed inside two slide rails respectively. Both lead screws are driven between two corresponding sliding blocks. A drive motor is rotatably installed at one end of each slide rail, and the two drive motors are fixedly installed at one end of each of the two corresponding slide rails. The lead screw transmission has high transmission efficiency and stability, which can ensure that the maintenance platform moves at a uniform and stable speed, reduce vibration and shaking, and provide a relatively stable working environment for maintenance personnel, thereby improving the quality and safety of maintenance work.

[0009] Preferably, the mounting assembly includes two mounting plates, which are respectively fixedly mounted on the top between four sliding blocks on both sides. Mounting seats are fixedly mounted on the four corners of one side of each mounting plate. Using screws, a simple fixing method, the assembly of the maintenance platform can be completed quickly, which is convenient for maintenance, replacement of parts or transportation of the platform. Unlike some fixing methods such as welding or riveting, which require special equipment and technology for disassembly, this method greatly improves disassembly efficiency.

[0010] Preferably, the platform assembly includes four fixing plates, each of which is fastened to the interior of a corresponding mounting base by screws. A work platform is fixedly installed on one side between the four fixing plates, a mounting frame is fixedly installed on one side of the work platform, and a ladder is fixedly installed on the other side of the work platform. A base plate is fixedly installed at the bottom between the mounting frame and the ladder, and casters are fixedly installed at the four corners of the bottom of the base plate. A control panel is fixedly installed at one end of the top of the work platform. A rotary switch and a lifting switch are installed on the surface of the control panel. The drive motor is electrically connected to an external power supply through the rotary switch. When the maintenance platform is moved, it can slide on the ground through the casters at the bottom, providing a certain degree of support for the equipment, reducing the load on the equipment, and making it less prone to damage under gravity.

[0011] Preferably, the protective assembly includes four sliding shells, which are respectively fixedly installed at the four corners of the top of the work platform. A safety fence is slidably installed inside the four sliding shells. One end of the safety fence is hinged to a fence gate. Four electric actuators are fixedly installed at the bottom of the safety fence. The bottom of each electric actuator is fixedly installed on the work platform. The electric actuators are electrically connected to an external power source through a lifting switch. The safety fence surrounds the work area, ensuring the safety of the workers. If there are differences in the height of the workers, the safety fence can be raised and lowered to a suitable height, further improving safety.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] By using screws to fasten the components, the assembly of the maintenance platform can be completed quickly, which facilitates the maintenance, replacement of parts or transportation of the platform. Unlike some fastening methods such as welding or riveting, which require specialized equipment and technology for disassembly, this greatly improves disassembly efficiency.

[0014] The sliding components eliminate the need for frequent setup and dismantling of temporary maintenance facilities as in traditional maintenance methods, greatly saving maintenance preparation time and allowing maintenance personnel to focus on the maintenance work itself, thereby improving overall maintenance efficiency.

[0015] The work area is completely enclosed by a protective fence, ensuring the safety of workers. The safety fence can be raised and lowered to a suitable height for workers of different heights, further enhancing safety. Attached Figure Description

Detailed Implementation

[0021] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0022] This application discloses a crane rail maintenance platform that is easy to assemble and disassemble.

[0023] See Figures 1-4The easily disassembled crane rail maintenance platform includes two slide rail bridges 1. A safety bar 17 is fixedly installed on one side of the top of the slide rail bridge 1. A bridge crane 2 is slidably installed on the top between the two slide rail bridges 1. Sliding components are fixedly installed on the outer sides of both slide rail bridges 1. A transmission component is installed inside the sliding component. An installation component for connection and disassembly is fixedly installed on one side of the sliding component. A platform component is fixedly installed inside one of the installation components. A protective component for safety is fixedly installed on the top of the platform component.

[0024] Furthermore, the sliding assembly includes four sliding brackets 3, two of which are fixedly installed on one side of a slide rail bridge 1, and the other two are fixedly installed on one side of another slide rail bridge 1. Each of the four sliding brackets 3 has two sliding blocks 4 slidably installed inside. When the drive motor 6 drives the lead screw 5 at the output end to rotate, the lead screw 5 drives the two corresponding sliding blocks 4 on the outer side to slide inside one of the sliding brackets 3. When the sliding blocks 4 move, they drive the mounting plate 7 connected to them to move together. The mounting plate 7 is fixed to the working platform 10 by screws, so when the sliding blocks 4 move, they drive the working platform 10 to move. The working platform 10 is supported by casters 15 installed at the bottom and moves horizontally on the ground, achieving the purpose of inspecting the entire slide rail bridge 1.

[0025] Furthermore, the transmission assembly includes two lead screws 5, which are rotatably installed inside two of the slide rail frames 3. Both lead screws 5 are drivenly connected between two corresponding sliding blocks 4. A drive motor 6 is rotatably installed at one end of each slide rail frame 3. The two drive motors 6 are fixedly installed at one end of each of the two corresponding slide rail frames 3. When the staff inspects the top of the slide rail bridge 1, they usually need to inspect the entire slide rail, so they need to move the work platform 10. By turning the switch on the control panel 16 on the top of the work platform 10, the corresponding drive motor 6 is started to rotate. When the drive motor 6 rotates, it drives the lead screw 5 at the output end to rotate.

[0026] Furthermore, the mounting assembly includes two mounting plates 7, which are respectively fixedly mounted on the top between the four sliding blocks 4 on both sides. Mounting seats 8 are fixedly mounted on the four corners of one side of the mounting plate 7. Pushing the entire maintenance platform allows it to move via the casters 15 mounted on the bottom of the base plate 14, causing the four fixing pieces 9 on the side of the work platform 10 to move towards the mounting seats 8, so that the fixing pieces 9 enter the interior of the corresponding mounting seats 8. The fixing pieces 9 are then secured by screws passing through the corresponding through holes in the middle of the fixing pieces 9 and the mounting seats 8, and by nuts. This fixes the work platform 10.

[0027] Furthermore, the platform assembly includes four fixing plates 9, which are all fastened to the interior of the corresponding four mounting seats 8 by screws. A work platform 10 is fixedly installed on one side between the four fixing plates 9, a mounting frame 13 is fixedly installed on one side of the work platform 10, and a ladder 12 is fixedly installed on the other side of the work platform 10. A base plate 14 is fixedly installed at the bottom between the mounting frame 13 and the ladder 12. Universal wheels 15 are fixedly installed at the four corners of the bottom of the base plate 14. A control panel 16 is fixedly installed at one end of the top of the work platform 10. A rotary switch and a lifting switch are installed on the surface of the control panel 16. The drive motor 6 is electrically connected to an external power supply through the rotary switch. After the work platform 10 is installed and fixed, the maintenance personnel climb up the ladder 12 and, after reaching the area of ​​the top work platform 10, lock one end of the safety rope to the safety bar 17, thus achieving the first layer of safety protection.

[0028] Furthermore, the protective assembly includes four sliding housings 18, which are fixedly installed at the four corners of the top of the work platform 10. A safety fence 11 is slidably installed inside the four sliding housings 18. A fence gate 19 is hinged to one end of the safety fence 11. Four electric actuators 20 are fixedly installed at the bottom of the safety fence 11. The bottom of each electric actuator 20 is fixedly installed on the work platform 10. The electric actuators 20 are electrically connected to an external power source through a lifting switch. After the safety rope is locked, the gate of the safety fence 11 is closed, forming a working environment surrounded by the safety fence 11, achieving a second layer of safety protection. When workers need to adjust the height of the safety fence 11 due to different heights, they control the electric actuators 20 through the lifting switch on the control panel 16. The four electric actuators 20 are electrically connected together and move synchronously, causing the top safety fence 11 to slide and rise and fall inside the four sliding housings 18, thereby achieving height adjustment. After the height adjustment is completed, the top of a slide rail bridge 1 can be inspected.

[0029] In this embodiment, during use: the entire maintenance platform is pushed and moved by the casters 15 mounted on the bottom of the base plate 14, causing the four fixing plates 9 on the side of the work platform 10 to move towards the mounting base 8, so that the fixing plates 9 enter the interior of the corresponding mounting base 8. A screw passes through the corresponding through hole in the middle of the fixing plate 9 and the mounting base 8, and a nut is used to tighten them, thereby fixing the work platform 10. After the work platform 10 is installed and fixed, maintenance personnel climb up the ladder 12 to the top of the work platform 10 area, and then lock one end of the safety rope to the safety bar 17. To achieve the first layer of safety assurance, after the safety rope is locked, the gate of the safety fence 11 is closed, creating a work environment surrounded by the safety fence 11, thus achieving the second layer of safety assurance. When workers need to adjust the height of the safety fence 11 due to different heights, the electric actuators 20 are controlled by the lifting switch on the control panel 16. The four electric actuators 20 are electrically connected together and move synchronously, causing the top safety fence 11 to slide and rise and fall inside the four sliding housings 18, thereby achieving height adjustment. After the height adjustment is completed, the top of a slide rail cable tray 1 can be inspected. During maintenance, when inspecting the top of the slide rail bridge 1, the entire slide rail needs to be inspected, so the work platform 10 needs to be moved. The corresponding drive motor 6 is started by rotating the rotary switch on the control panel 16 on the top of the work platform 10. When the drive motor 6 rotates, it drives the lead screw 5 at the output end to rotate. When the drive motor 6 drives the lead screw 5 to rotate, the two corresponding sliding blocks 4 on the outer side of the lead screw 5 slide inside a slide rail frame 3. When the sliding blocks 4 move, they drive the mounting plate 7 connected to them to move together. The mounting plate 7 and the work platform 10 are already... The sliding block 4 is fixed by screws, so when the sliding block 4 moves, it will drive the working platform 10 to move. The working platform 10 is supported by the universal wheels 15 installed at the bottom and moves horizontally on the ground to achieve the purpose of maintenance of the entire slide rail bridge 1. After the maintenance of one slide rail bridge 1 is completed, the fixing of the working platform 10 to the mounting plate 7 is removed, and the working platform 10 is pushed to the mounting plate 7 of another slide rail bridge 1 by the universal wheels 15. The screws pass through the corresponding through holes in the middle of the fixing plate 9 and the mounting seat 8, and the nuts are tightened to fix the working platform 10, so as to carry out maintenance of the other slide rail bridge 1.

[0030] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
