Description

Technical Field

[0001] The utility model relates to the technical field of ventilator equipment, in particular to a hoisting stability device for a ventilator coupling housing. Background Technique

[0002] The coupling guard plays a crucial role in the safe use of equipment and on-site maintenance and repair. In order to facilitate maintenance, the housing needs to be designed with an openable structure. However, some inconvenient factors have been found during the production, use and transportation processes of the openable structure. Firstly, in terms of production, since the openable housing is divided into upper and lower parts, during processing, the upper and lower parts of the housing need to be spot-welded firmly to make it a whole, and then the weld points are polished off later and divided into upper and lower parts again. This increases the production steps and requires more production time and manpower. Secondly, there are also inconvenient factors during the transportation and hoisting of the openable housing. Because the openable housing is divided into upper and lower parts and no stable measures are adopted to connect the upper and lower parts, the openable housing is prone to disintegration during hoisting and transportation, causing the upper and lower parts to fall off. Content of the Utility Model

[0003] In order to improve the convenience of the housing during on-site use, the utility model provides a hoisting stability device for a ventilator coupling housing.

[0004] The hoisting stability device for a ventilator coupling housing provided by the utility model adopts the following technical scheme:

[0005] A hoisting stability device for a ventilator coupling housing includes a housing body and two guard plates. The outer surfaces of the two guard plates are fixedly connected to the inside of the housing body. The housing body includes an upper housing body, two lower housing bodies and heavy-duty hinges. One side of the upper housing body is connected to one of the lower housing bodies through a heavy-duty hinge.

[0006] By adopting the above technical scheme, with the heavy-duty hinge as the center, the upper housing body can rotate around the heavy-duty hinge by a certain angle until it touches the two lower housing bodies, without first spot-welding the upper and lower parts of the housing firmly to make it a whole and then polishing off the weld points and dividing them into upper and lower parts again, which is beneficial to improving the convenience of the housing body during on-site use.

[0007] Preferably, the bottom of the upper housing body is lapped on the tops of the two lower housing bodies. A handle is fixedly connected to the outer surface of the upper housing body. Through holes two are opened at both ends of the bottoms of the two lower housing bodies.

[0008] Preferably, two L-shaped connecting plates are fixedly connected to the bottom of the upper housing body and the top of the other lower housing body respectively. Through holes one are opened on the horizontal plates of each L-shaped connecting plate. Every two through holes one form a group. Fixing bolts are inserted into the interiors of each group of through holes one.

[0009] Preferably, butterfly nuts are threadedly connected to the outer surfaces of the two fixing bolts, and the bottoms of the two butterfly nuts are clamped to the outer surfaces of the corresponding L-shaped connecting plates.

[0010] By adopting the above technical solution, the connection of the fixing bolts and the butterfly nuts enables the upper shell and the other lower shell to be connected, thus solving the problem that the open type is prone to disintegration during hoisting and transportation, causing the upper and lower parts to fall off. Moreover, the butterfly nuts are convenient to open, and in cooperation with the heavy-duty hinges, the rapid opening of the shell can be achieved.

[0011] Preferably, the shell and the two guard plates are both U-shaped, and the two guard plates are linearly arranged along the length direction of the shell. One of the guard plates is fixedly connected to the inner wall of one side of the shell, and the other guard plate is located inside the shell.

[0012] By adopting the above technical solution, the two arc regions of the shell and the two guard plates are convenient for clamping the arc regions of the ventilator, enhancing the firmness of the ventilator.

[0013] Preferably, the two guard plates each include an upper plate and a lower plate, and the bottom of the upper plate overlaps the top of the lower plate.

[0014] By adopting the above technical solution, after the upper shell and the lower shell are closed to enclose the ventilator, the upper plate and the lower plate are also combined to cover the ventilator, protecting the outer surface of the ventilator.

[0015] Preferably, the tops of the two upper plates are fixedly connected to the inside of the upper shell, one sides of the two lower plates are fixedly connected to the corresponding sides of the lower shell, and the height of the bottom of the lower plate is higher than the height of the bottom of the lower shell.

[0016] By adopting the above technical solution, the space at the position in the shell where there is no guard plate is relatively large, which is convenient for placing the air outlet of the casing of the ventilator or other areas.

[0017] In summary, the utility model has the following beneficial technical effects:

[0018] 1. The device is provided with a split upper shell, a lower shell and an L-shaped connecting plate. An L-shaped connecting plate is added to one side surface of the upper shell and one of the lower shells, and then the corresponding two through holes II are fixed with fixing bolts. One side of the other lower shell and the other side of the upper shell are connected by heavy-duty hinges, so that the upper shell and the two lower shells form a stable whole. Then, by pulling the handle, the upper shell rotates around the heavy-duty hinge, thereby opening and closing the shell, which improves the convenience of the cover shell in on-site use. The enhanced stability also increases safety considerations. At the same time, during installation and transportation, due to the enhanced integrity of the cover shell, it provides safety and convenience for hoisting. Moreover, directly bending the bottom of the upper shell and the top of the lower shell can also achieve the effect of the L-shaped connecting plate, which simplifies the production process of the upper shell and the lower shell due to the L-shaped connecting plate on the shell during production, and is conducive to reducing production costs and management costs;

[0019] 2. The device is set to connect the upper shell and the lower shell through fixing bolts and nuts. The fixing bolts penetrate through the inside of the L-shaped connecting plate on the upper shell and the L-shaped connecting plate on the lower shell, and the wing nuts are connected to the outer surface of the bolts and clamped on the outer surface of the L-shaped connecting plate on the upper shell, thereby locking the shell and making the upper and lower parts of the cover shell a stable whole. With the wing nuts, on-site workers can easily remove the fixing nuts without the help of professional tools, realizing the quick opening of the cover shell, improving the convenience of the shell in on-site use, and the enhanced stability also increases safety considerations.

[0028] The following further elaborates on the present utility model in conjunction with the attached Figures 1-5 drawings.

[0029] An embodiment of the present utility model discloses a hoisting stability device for a ventilator coupling housing.

[0030] Referring to Figure 1 and Figure 4 , it includes a housing and two guard plates 7. The housing is the coupling guard. During transportation, the two guard plates 7 can limit the movement of the ventilator and prevent the ventilator from leaving the interior of the housing. The outer surfaces of the two guard plates 7 are fixedly connected to the interior of the housing. The housing includes an upper housing 1, two lower housings 2, and heavy-duty hinges 4. One side of the upper housing 1 is connected to one of the lower housings 2 through a heavy-duty hinge 4. One side of one lower housing 2 and one side of the upper housing 1 are connected through a heavy-duty hinge 4. The other side of the other lower housing 2 and the other side of the upper housing 1 are connected through an L-shaped connecting plate 5 and a fixing bolt 3.

[0031] Referring to Figure 1 and Figure 2 and Figure 4 , the bottom of the upper housing 1 is lapped on the tops of the two lower housings 2. The outer surface of the upper housing 1 is fixedly connected with a handle 8. When the housing needs to be opened, the worker pulls the handle 8 to rotate the upper housing 1 away from the lower housing 2, that is, rotates clockwise to open. When the opened housing needs to be closed, the worker pulls the handle 8 to rotate the upper housing 1 towards the lower housing 2, that is, rotates counterclockwise to close. Through holes two are opened at both ends of the bottoms of the two lower housings 2.

[0032] Referring to Figure 1 and Figure 2 , both the bottom of the upper housing 1 and the top of the other lower housing 2 are fixedly connected with two L-shaped connecting plates 5. Each horizontal plate of each L-shaped connecting plate 5 is provided with a through hole one. Two through holes one form a group. A fixing bolt 3 is inserted into the interior of each group of through holes one. The fixing bolt 3 penetrates through the interiors of the two through holes, that is, the fixing bolt 3 penetrates through the interiors of the L-shaped connecting plates 5 on the upper housing 1 and the L-shaped connecting plates 5 on the lower housing 2, thereby connecting one side of the upper housing 1 and one side of one of the lower housings 2.

[0033] Referring to Figure 1 and Figure 2 and Figure 5, the outer surfaces of the two fixing bolts 3 are both threadedly connected with wing nuts 6. With the wing nuts 6 for fixation, on-site workers can easily remove the wing nuts 6 without the aid of professional tools. The bottoms of the two wing nuts 6 are both clamped on the outer surfaces of the corresponding L-shaped connecting plates 5. The two L-shaped connecting plates 5 that connect the upper shell 1 and the lower shell 2 are connected by the fixing bolts 3, and then the fixing bolts 3 are locked by the wing nuts 6, thereby completely connecting the upper shell 1 and the two lower shells 2. The second through hole of the lower shell 2 is then connected to other components, thus locking the ventilator in a position, which is beneficial to avoiding the situation where the upper shell 1 and the lower shell 2 are disassembled during the transportation of the ventilator. Since the L-shaped connecting plates 5 can also be made by directly bending the upper shell 1 and the lower shell 2, it simplifies the production process of the upper shell 1 and the lower shell 2 in production, which is beneficial to reducing production costs and management costs.

[0034] Refer to Figure 1 , Figure 2 , Figure 3 , the shell and the two guard plates 7 are both U-shaped. The two guard plates 7 are linearly arranged along the length direction of the shell. One of the guard plates 7 is fixedly connected to the inner wall of one side of the shell, and the other guard plate 7 is located inside the shell. One of the guard plates 7 is in contact with one side of the shell, and the other guard plate 7 is at a certain distance from one side of the shell, thereby leaving a margin for the air outlet of the centrifugal ventilator and avoiding the air outlet of the centrifugal ventilator exceeding the protection range of the shell.

[0035] Refer to Figure 4 , the two guard plates 7 both include an upper plate 71 and a lower plate 72. The bottom of the upper plate 71 overlaps the top of the lower plate 72. When the bottom of the upper shell 1 overlaps the tops of the two lower shells 2, the shell is in a closed state, and the upper plate 71 and the lower plate 72 are closed, forming an open covering space with the upper shell 1 and the lower shell 2 to protect the ventilator. At the same time, the shell can be placed stably on the ground or other carriers, which is convenient for transporting the ventilator.

[0036] Refer to Figure 4 , the tops of the two upper plates 71 are both fixedly connected to the inside of the upper shell 1, and one side of the two lower plates 72 is both fixedly connected to the corresponding side of the lower shell 2. The height of the bottom of the lower plate 72 is higher than the height of the bottom of the lower shell 2. The sizes of the parts on the outer shape of the ventilator are different, and there are parts with larger protrusions. The closed upper plate 71 and lower plate 72 cover a part of the ventilator with the upper shell 1 and the lower shell 2, and the other part of the ventilator is exposed inside the lower shell 2.

[0037] The implementation principle of a lifting stability device for a ventilator coupling housing in an embodiment of the present utility model is as follows:

[0038] 1. An L-shaped connecting plate 5 is added to one side surface of the upper shell 1 and one of the lower shells 2, and then the corresponding two through holes II are fixed with fixing bolts 3. One side of the other lower shell 2 and the other side of the upper shell 1 are connected by a heavy-duty hinge 4, so that the upper shell 1 and the two lower shells 2 form a stable whole. Then, by pulling the handle 8, the upper shell 1 rotates around the heavy-duty hinge 4, thereby opening and closing the shell. Furthermore, the convenience of the cover shell in on-site use is improved in terms of use, and the enhanced stability also increases the safety consideration. At the same time, due to the enhanced integrity of the cover shell during installation and transportation, it provides safety and convenience for hoisting;

[0039] 2. Place the ventilator inside the shell and the guard plate 7, then pull the handle 8 to drive the upper shell 1 to rotate towards the lower shell 2 until the horizontal plates of the two L-shaped connecting plates 5 are in contact. Then insert the fixing bolt 3, screw in the wing nut 6 to lock the two L-shaped connecting plates 5. Then lock the through hole II of the lower shell 2 to the workbench or the loading platform or other items with other screws or fixing parts, and move the hoisted shell to drive the ventilator to move.

[0040] The above are all the preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention shall be covered within the protection scope of the present invention.
