Description

Technical Field

[0001] This utility model belongs to the field of engineering machinery protection technology, specifically relating to a protective door panel for engineering machinery with an adjustable structure. Background Technology

[0002] Protective doors for construction machinery play a crucial role in industrial production and manufacturing, primarily protecting equipment and personnel. During the operation of construction machinery, there are often hazardous elements such as rotating mechanical parts, high-speed chains or belts, and sharp blades. Protective doors physically isolate these hazardous areas, preventing personnel from approaching them and thus reducing the risk of cuts, burns, and other accidents.

[0003] After installation and commissioning, protective doors for construction machinery typically require both doors to be tightly closed to ensure safe isolation of the work area inside. To further enhance safety, a guard is often stationed on the outside of the door to monitor its status and prevent unauthorized opening, reflecting a strong emphasis on the security of the work area. However, this arrangement can present some inconveniences in practice.

[0004] Especially when maintenance personnel inside the door are performing routine maintenance or emergency repairs, they may frequently need to receive tools, spare parts, or other necessary supplies from personnel outside the door. In such cases, if the door guards outside have to open and close the door every time an item is passed, the entire workflow will become cumbersome and time-consuming, not only reducing work efficiency but also potentially hindering the smooth progress of maintenance work. Utility Model Content

[0005] The purpose of this invention is to provide a protective door panel for engineering machinery with an adjustable structure. This addresses the problem that maintenance personnel inside the door may frequently need to receive tools, spare parts, or other necessary supplies from personnel outside the door during routine maintenance or emergency repairs. In such cases, if the door needs to be opened and closed repeatedly by the guards outside, the entire workflow becomes cumbersome and time-consuming, reducing efficiency and potentially hindering the smooth progress of maintenance work.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a protective door panel for engineering machinery with an adjustable structure, comprising a frame, wherein two door panels are symmetrically installed inside the frame via hinges, and a rectangular groove is formed through each door panel;

[0007] A docking post is fixedly connected to the inner walls of the upper and lower sides, and a turntable is movably connected to the other side of each docking post. A connecting rod is fixedly installed between the two turntables, and a transparent plate is fixedly installed on both sides of the connecting rod.

[0008] In order to enable operators on both sides of the door panel to pass tools via the turntable and protective ring without opening the door panel, as a preferred embodiment of the protective door panel for engineering machinery with an adjustable structure of this utility model, a protective ring is fixedly installed on the surface of the turntable below the rectangular groove, and the outer wall of the protective ring is in contact with the inner wall of the rectangular groove.

[0009] To allow operators on both sides of the door panel to communicate visually through the transparent panel, and to divide the protective ring into two areas, as a preferred embodiment of the protective door panel for engineering machinery with an adjustable structure of this utility model, the outer wall of the transparent panel on the side away from the connecting rod is in contact with the inner wall of the protective ring, and the upper and lower outer walls of the transparent panel are in contact with the outer wall of a turntable, respectively.

[0010] In order to enable the protrusions driven by the rotation of the turntable to pass through by pushing the deformation of the protruding column, as a preferred protective door panel for engineering machinery with an adjustable structure of this utility model, two sets of protruding columns are fixedly installed on the inner walls of the upper and lower sides of the rectangular groove, with three protruding columns in each set. The end of the protruding column away from the inner wall of the rectangular groove has a semi-circular structure, and the protruding column is made of rubber.

[0011] In order to enable the turntable to rotate on one side of the docking column, as a preferred protective door panel for engineering machinery with an adjustable structure of this utility model, six sets of protrusions are installed at equal intervals on the side of the turntable facing the inner wall of the rectangular groove, and a rotating component is fixedly installed at the center end of the side of the turntable facing the inner wall of the rectangular groove.

[0012] The rotating component is rotatably installed inside the docking column, and the turntable forms a rotating structure with the docking column through the rotating component.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] When maintenance personnel on both sides of the door panel need to exchange tools or assist each other, the operator on one side places the tool into the turntable below, and then the operator on the other side moves the turntable. The two turntables then rotate between the two docking posts, causing the turntable on the side with the exchange tool to rotate to the other side. At this point, the personnel on the other side of the door panel can exchange tools without opening the door panel, thus improving the convenience of complementary work between the personnel on both sides of the door panel.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 The present invention provides the following technical solution: a protective door panel for engineering machinery with an adjustable structure, including a frame 1, two door panels 2 are symmetrically installed inside the frame 1 via hinges, and a rectangular groove 3 is provided through each door panel 2;

[0023] After the frame 1 is connected to the two door panels 2, it forms the protective door panel for construction machinery involved in this technical solution. When maintenance personnel need to isolate the surrounding area from the outside when maintaining construction machinery, it is necessary to use a fence to isolate the construction machinery. Finally, the protective door panel for construction machinery built by the frame 1 and the two door panels 2 is used to seal the opening, thereby preventing unauthorized personnel from entering during maintenance.

[0024] A docking post 4 is fixedly connected to the inner walls on the upper and lower sides respectively. A turntable 5 is movably connected to the other side of each docking post 4. A connecting rod 6 is fixedly installed between the two turntables 5. A transparent plate 8 is fixedly installed on both sides of the connecting rod 6.

[0025] Preferably, a protective ring 7 is fixedly installed on the surface of the turntable 5 below the rectangular groove 3, and the outer wall of the protective ring 7 is in contact with the inner wall of the rectangular groove 3.

[0026] In actual use, when the tool is placed on the turntable 5 below, the protective ring 7 will effectively surround the tool inside the turntable 5, thereby preventing the tool from accidentally falling off when the turntable 5 rotates.

[0027] Preferably, the outer wall of the transparent plate 8 on the side away from the connecting rod 6 is in contact with the inner wall of the protective ring 7, and the upper and lower outer walls of the transparent plate 8 are in contact with the outer wall of a turntable 5 respectively.

[0028] Preferably, two sets of protruding posts 31 are fixedly installed on the inner walls of the upper and lower sides of the rectangular groove 3, with three protruding posts 31 in each set. The end of the protruding post 31 away from the inner wall of the rectangular groove 3 is a semi-circular structure, and the protruding post 31 is made of rubber.

[0029] In actual use, when the turntable 5 rotates, it will drive the protrusion 51 to rotate. When the protrusion 51 rotates, it will push the protrusion 31, so that the protrusion 31 will deform, allowing the currently contacting protrusion 51 to pass through the protrusion 31.

[0030] Preferably, six sets of protrusions 51 are installed at equal intervals on one side of the turntable 5 facing the inner wall of the rectangular groove 3, and a rotating part 52 is fixedly installed at the center end of the side of the turntable 5 facing the inner wall of the rectangular groove 3.

[0031] The rotating component 52 consists of a cylinder and a disk. The docking post 4 has an inner cavity that matches the size of the rotating component 52. In this way, when the turntable 5 rotates, it can rotate smoothly in the inner cavity of the docking post 4 through the rotating component 52.

[0032] The rotating component 52 is rotatably installed inside the docking column 4, and the turntable 5 forms a rotating structure with the docking column 4 through the rotating component 52.

[0033] In practical use, when maintenance personnel of engineering machinery located on both sides of the door panel 2 need to quickly exchange tools or assist each other, the adjustment structure provided by this technical solution can facilitate the quick exchange.

[0034] Specifically, the operator on one side of door panel 2 simply places the tool to be exchanged on the turntable 5 below. Then, the maintenance personnel on the other side of door panel 2 gently turn the other turntable 5, causing both turntables 5 to rotate via the two docking posts 4. This design ensures that the turntables 5 can move smoothly and steadily between the two docking points, while the turntable 5 containing the exchange tool rotates to the opposite side with this action.

[0035] At this point, the maintenance personnel on the other side of door panel 2 can easily obtain the necessary tools directly through this adjustment structure without interrupting their current work or spending time and effort opening door panel 2. This solution not only greatly improves the efficiency of tool exchange but also significantly enhances the complementarity and collaboration between the personnel on both sides of door panel 2, making the entire maintenance process smoother and more efficient.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
