Description

Technical Field

[0001] This application relates to the technical field of mechanical equipment maintenance, and in particular to a temporary safety fence for mechanical equipment maintenance. Background Technology

[0002] Mechanical equipment refers to a device or system composed of metal or other materials that converts input energy (such as electrical energy, thermal energy, chemical energy, etc.) into mechanical energy or other forms of energy through a series of interconnected or relatively moving parts. Mechanical equipment maintenance is an important technical activity for maintaining, restoring, and improving the technical condition of equipment, encompassing multiple aspects such as equipment upkeep, equipment inspection and testing, and equipment repair.

[0003] When performing maintenance on mechanical equipment, due to the large size of some equipment or to alert users that the equipment is under maintenance, a temporary safety fence is needed to enclose the machinery being maintained. However, traditional fences lack length adjustment, making them inconvenient to use. Therefore, to solve the above problems, this application provides a temporary safety fence for mechanical equipment maintenance.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0005] To address the issue that mechanical equipment maintenance requires enclosure with fencing, but traditional fencing lacks length adjustment functionality, this application provides a temporary safety fencing for mechanical equipment maintenance.

[0006] This application provides a temporary safety fence for the maintenance of mechanical equipment, including a support plate and a fixed base below it. A rotating rod is rotatably arranged inside the support plate, and the fence body is wrapped around the rotating rod. One end of the fence body is fixedly connected to the side wall of the rotating rod, and the other end is disposed through the right side wall of the support plate. The rotating rod can be locked when it rotates, and the length of the fence body pulled out after locking is fixed.

[0007] Preferably, the rotating rod passes through the upper wall of the support plate and is rotatably connected thereto, and a lower toothed ring is sleeved on the outer wall of the rotating rod and coaxially fixedly connected thereto.

[0008] Preferably, the upper wall of the support plate is provided with an upper toothed ring, and the rotating rod passes through the upper toothed ring and is rotatably connected to it.

[0009] Preferably, both sides of the upper toothed ring are fixedly connected to a fixing plate, and the lower wall of the fixing plate is fixedly connected to a telescopic column. The lower end of the telescopic column is fixedly connected to the upper wall of the support plate, and the fixing plate is elastically connected to the upper wall of the support plate by a spring.

[0010] Preferably, the upper toothed ring is located above the lower toothed ring, and the upper toothed ring descends to mesh with the lower toothed ring.

[0011] Preferably, a turntable is fixedly connected to the upper end of the rotating rod.

[0012] Preferably, a fixing strip is fixedly connected to the side of the enclosure body away from the rotating rod, and a plug is fixedly connected to both the upper and lower ends of the fixing strip, and a plug plate is fixedly connected to the lower wall of each plug.

[0013] Preferably, the left side wall of the support plate is fixedly connected to two fixing blocks, each of which has a through slot. The insert plate in one device is slidably connected to the fixing block in the other device through the slot in the other device.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] By lifting the fixing block and pulling the fence body, the rotating rod can rotate smoothly. After pulling to the appropriate length, insert the insert plate into the slot, lift the fixing block and rotate the turntable to make the rotating rod rotate, tightening the fence body. Release the fixing block, and due to the action of the spring, the upper toothed ring moves downward. Slightly rotate the handle to make the upper and lower toothed rings mesh, limiting the rotation of the rotating rod and thus fixing the fence body. Compared with the traditional method, multiple fence bodies can be connected quickly and the length of the fence body can be effectively fixed, making the installation of temporary safety fences faster and more convenient.

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

[0022] Example 1

[0023] Reference Figure 1-4 A temporary safety fence for the maintenance of mechanical equipment includes a support plate 1 and a base 2 fixed below it. A rotating rod 9 is rotatably installed inside the support plate 1. A turntable 10 is fixedly connected to the upper end of the rotating rod 9. Rotating the turntable 10 causes the rotating rod 9 to rotate. A fence body 5 is wrapped around the rotating rod 9. One end of the fence body 5 is fixedly connected to the side wall of the rotating rod 9, and the other end passes through the right side wall of the support plate 1.

[0024] A rotating rod 9 is disposed through and rotatably connected to the upper wall of the support plate 1. A lower toothed ring 12 is sleeved on and coaxially fixedly connected to the outer wall of the rotating rod 9. An upper toothed ring 11 is disposed on the upper wall of the support plate 1, and the rotating rod 9 is disposed through and rotatably connected to the upper toothed ring 11. Fixed plates 13 are fixedly connected to both sides of the upper toothed ring 11. Telescopic columns 14 are fixedly connected to the lower wall of the fixed plates 13. The lower ends of the telescopic columns 14 are fixedly connected to the upper wall of the support plate 1. The fixed plates 13 are elastically connected to the upper wall of the support plate 1 by springs 15. The upper toothed ring 11 is located above the lower toothed ring 12. When the upper toothed ring 11 descends, it meshes with the lower toothed ring 12.

[0025] A fixing strip 7 is fixedly connected to the side of the enclosure body 5 away from the rotating rod 9. Both ends of the fixing strip 7 are fixedly connected to the insert block 6, and the lower wall of the insert block 6 is fixedly connected to the insert plate 8. Two fixing blocks 3 are fixedly connected to the left side wall of the support plate 1. Each fixing block 3 has a through slot 4. The insert plate 8 in one device is slidably connected to the fixing block 3 in the other device through the slot 4 in the other device.

[0026] In actual use, first lift the fixing block 3 and pull the fence body 5. At this time, the rotating rod 9 can rotate smoothly. After the fence body 5 is pulled to a suitable length, insert the insert plate 8 into the slot 4, lift the fixing block 3 and rotate the turntable 10 to make the rotating rod 9 rotate, tightening the fence body 5. Release the fixing block 3. Due to the action of the spring 15, the upper toothed ring 11 moves downward. Slightly rotate the turntable 10 to make the upper toothed ring 11 and the lower toothed ring 12 mesh, limiting the rotation of the rotating rod 9, thereby fixing the fence body 5. At this time, the fence body 5 is slightly loose, but it does not affect its protection of mechanical equipment. This device can quickly connect multiple fence bodies 5 and effectively fix the fence body 5 to prevent it from stretching, making the installation of temporary safety fences faster and more convenient.
