Compared with the prior art, the manhole sealer has the following characteristics and advantages:
1. the manhole sealer has a compact structure, is convenient to store and carry, and is convenient to use.
2. The manhole sealer can achieve the purposes of warning workers and sealing manholes.
The features and advantages of the present invention will become more apparent from the detailed description of the invention when taken in conjunction with the drawings.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below, and it is obvious that the drawings in the following description are some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.
Figure 1 is a schematic structural view of a manhole closure in an embodiment of the invention;
fig. 2 is a first schematic view of a manhole closure and a manhole flange according to an embodiment of the present invention;
fig. 3 is a second schematic view of a connection between a manhole closure and a manhole flange according to an embodiment of the present invention;
wherein,
11. the device comprises a static rod, 12 a moving rod, 2 a hook-shaped clamping part, 21 a blocking piece, 3 an upper locking column, 31 a locking hole, 41 a warning board, 42 an assembling part, 43 an adjusting screw, 5 a manhole flange, 51 a bolt hole.
Detailed Description
As shown in fig. 1 to 3, the present embodiment provides a manhole closure including a warning plate 41, a support rod, a hook-shaped engaging portion 2, and a locking portion. The bracing piece includes quiet pole 11 and moves pole 12, moves pole 12 and can stretch out and draw back for quiet pole 11, moves the total length after pole 12 and the extension of quiet pole 11 and just in time can span the manhole mouth, when the manhole closure does not use, will move pole 12 and contract in quiet pole 11, has reduced the whole volume of manhole closure, portable, deposit. The warning board 41 is fixedly connected with an assembly part 42, the assembly part 42 is provided with an assembly opening capable of being inserted into the supporting rod, and the assembly part 42 is movably connected with an adjusting screw 43 at the assembly opening. In this embodiment, the stationary bar 11 of the support bar is inserted into the mounting hole of the warning board 41, and when the warning board 41 is adjusted to be located at the center of the manhole, the adjusting screw 43 is screwed to fix the position of the warning board 41. One end of the hook-shaped clamping part 2 is hinged with the tail end of the static rod 11 of the supporting rod, and the two sides of the hinged part at one end of the hook-shaped clamping part are fixedly connected with blocking pieces 21 so as to prevent the hook-shaped clamping part 2 from being manually and easily detached from the supporting rod, and the upper lock column 3 in the locking part is fixedly connected with the tail end of the moving rod 12 of the supporting rod; of course, one end of the hook-shaped engaging portion 2 may be hinged to the end of the movable rod 12 of the support rod, and the upper lock post 3 of the lock portion may be fixedly connected to the end of the stationary rod 11 of the support rod. The other end of the hook-shaped engaging portion 2 is engageable with a bolt hole 51 of the manhole flange 5, and the upper lock cylinder 3 is insertable into the bolt hole 51 of the manhole flange 5. The upper lock column 3 is provided with a plurality of lock holes 31 at equal intervals, and the manhole closure can be locked to the manhole flange 5 by hooking the locks to the lock holes 31 while engaging the bolt holes 51 with the hook-shaped engaging portions. The equidistant plurality of locking holes 31 ensures that the manhole closure is suitable for a plurality of series of manhole flanges 5 of different thickness. As shown in fig. 2, the plane of the end of the other end of the hook-shaped clamping part 2 is lower than the plane of the support rod but the distance between the end of the other end of the hook-shaped clamping part and the lower end surface of the support rod is less than the thickness of the manhole flange, i.e. d1< d 2; alternatively, as shown in fig. 3, the plane of the end of the other end of the hook-shaped engaging portion 2 is higher than the lower end surface of the support rod. Of course, the hook-shaped engaging portion 2 may be deformed in various ways to engage the hook-shaped engaging portion 2 with the bolt hole 51, and will not be described in detail herein. In this way, the hook-shaped clamping part 2 and the locking part are clamped and locked with the manhole flange 5, so that the hook-shaped clamping part 2 cannot be easily detached from the bolt hole 51 by other people without opening the locking part in the use process of the manhole closure.
In the use process of the manhole closure device, the hook-shaped clamping part 2 is clamped in the bolt hole 51 of the manhole flange 5, then the support rod is rotated and extended through the relative displacement of the static rod 11 and the movable rod 12, the upper locking column 3 is clamped in the bolt hole 51 on the other side of the manhole flange 5, the warning board 41 is adjusted in the process, so that the warning board 41 is located at the central position of the manhole, the adjusting screw 43 is screwed, the lock is hung on the lock hole 31, and the manhole closure device can be locked on the manhole flange 5, so that the purposes of warning workers and closing the manhole are achieved.
It is to be understood that the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and those skilled in the art may make modifications, alterations, additions or substitutions within the spirit and scope of the present invention.
