Description

Technical Field

[0001] This utility model proposes an auxiliary device for well construction, belonging to the field of municipal construction tools. Background Technology

[0002] Manholes are widely present in urban and community roads. Municipal workers and property management personnel frequently need to enter manholes for maintenance and repair. During maintenance, warning barriers need to be set up around the manhole opening. Currently, simple warning devices such as cones and barriers are generally used during manhole construction to warn passersby of the danger of manholes. Although such auxiliary warning devices can play a warning role, they are often moved and ignored by naughty children. To address this issue, those skilled in the art have developed and designed auxiliary devices that can be fixed to the manhole and are not easily moved. However, the size of the protective area formed by such devices at the manhole opening is relatively fixed and cannot be adjusted according to the actual situation. Moreover, the auxiliary devices only have a protective function and cannot provide foot support for operators entering the manhole. Summary of the Invention

[0003] This utility model provides an auxiliary device for well construction to solve the problems existing in the prior art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a well construction auxiliary device, comprising a base, a fixing component on the lower side of the base and a protective component on the upper side, wherein the fixing component includes a first fixing part and a second fixing part, wherein the first fixing part and the second fixing part are arranged opposite to each other, and in use, both the first fixing part and the second fixing part are located inside the well and are in contact with the side wall of the well, so that the two fixing parts can fix the base to the edge of the well; the protective component forms a well protection area on the upper side of the base.

[0005] Further, as a preferred embodiment, the base is annular, with a diameter larger than that of the well. Two sets of mounting holes for fixing components are symmetrically arranged on the annular base. The fixing components are movably connected to the base through these mounting holes, and fastening bolts are provided on the sidewalls of the mounting holes to securely connect the fixing components to the base. Several fixed support rods for installing protective components are threadedly connected to the upper side of the base. Insertion holes are provided at the upper ends of the fixed support rods along their length for installing the protective components.

[0006] As a further preferred embodiment, both the first fixing part and the second fixing part include a horizontal bar and a vertical ladder. The horizontal bar is inserted into the mounting hole, and one end of the horizontal bar located inside the annular base is fixedly connected to the upper end of the vertical ladder.

[0007] As a further preferred embodiment, the protective assembly includes several enclosures that correspond one-to-one with the fixed support rods. Each enclosure consists of a support rod and a warning shield. The support rod includes a vertical rod and a hanging rod that is fixedly connected to the vertical rod. The warning shield is rectangular in shape, with one side of the warning shield fitted onto the hanging rod and the other side hanging down.

[0008] Further preferably, the hanging rod is arc-shaped. When the enclosure is installed on the fixed support rod, the inner arc of the hanging rod faces towards the center of the base. The closer the center of the arc of the hanging rod is to the center of the base, the more convergent the hanging rod is; the farther the center of the arc of the hanging rod is from the center of the base, the more extended the hanging rod is. Further preferably, the end of the vertical rod away from the hanging rod is detachably inserted into the insertion hole at the upper end of the fixed support rod, and the vertical rod can rotate relative to the fixed support rod to change the size of the manhole protection area formed by the enclosure.

[0009] As a further preferred embodiment, the warning shield is made of reflective cloth, with the upper end of the warning shield forming a sleeve for fitting onto the hanging rod and the lower end provided with a weight block.

[0010] 1. The fixing component of this utility model is inserted into the well, and the two fixing parts are arranged opposite to each other and abut against the inner wall of the well. In this way, the base can be firmly and stably fixed around the edge of the well opening through the fixing parts, and it is not easy to be moved.

[0011] 2. The fixing part of this utility model includes a vertical ladder. When in use, the two fixing parts are arranged opposite each other to form a support point on the inside of the pipe well for the operator to step on, which makes it easy for the operator to climb into the pipe well without the need to set up an additional ladder.

[0012] 3. The insertion hole at the end of the support rod relative to the fixed support rod is rotatable. This allows the size of the hanging rod to be adjusted by rotating the support rod, thereby changing the size of the protective area formed by the protective component, which is more beneficial for protection during the construction of the manhole.

[0013] 4. When not in use, each component of this utility model can be disassembled into a single part, and the individual parts are relatively small in size, making them easy to transport and store. Attached Figure Description

[0019] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0020] This embodiment presents a manhole construction auxiliary device. The purpose of this invention is to provide a manhole construction protection tool that can adjust the size of the protected area according to the construction site conditions. Specifically, it allows for adjustment of the appropriate protected area size based on traffic flow, pedestrian flow, and construction operations. Furthermore, this device can also create support points for operators to step on or a ladder-like structure for climbing within the manhole. It should be noted that the manhole in this application refers to the manhole to be constructed.

[0021] like Figures 1-5 As shown, this embodiment specifically discloses a well construction auxiliary device, including a base 100. A fixing component 200 is provided on the lower side of the base 100 and a protective component 300 is provided on the upper side. The fixing component 200 is used to stably hold the base 100 and the protective component 300 provided on the upper side of the base 100 at the edge of the well opening, preventing the device from falling over or being displaced away from the edge of the well opening due to a small external force and losing its protective function. The main purpose of the protective component 300 is to form a relatively closed area around the edge of the well opening, so as to prevent irrelevant personnel from accidentally entering the construction area around the edge of the well opening due to attention problems and causing danger.

[0022] In some embodiments, the fixing component 200 includes a first fixing part and a second fixing part, wherein both the first fixing part and the second fixing part are movably connected to the base 100. The first fixing part and the second fixing part are arranged opposite to each other and can move closer to or further away from each other. In use, the distance between the first fixing part and the second fixing part is first adjusted to be less than the inner diameter of the well, so that the first fixing part and the second fixing part can be inserted into the well. Then, the distance between the first fixing part and the second fixing part is reduced to be equal to or close to the inner diameter of the well, that is, both the first fixing part and the second fixing part are located inside the well and are in contact with the side wall of the well. In this way, the two fixing parts can fix the base 100 to the edge of the well. The protective component 300 forms a well protection area on the upper side of the base 100.

[0023] In some embodiments, the base 100 is made of iron or high-strength plastic fiber and is in the shape of a ring. Of course, the base 100 can also be a square ring with a diameter or side length greater than the diameter of the well. This way, the base 100 will not fall into the well when it is placed at the edge of the well opening.

[0024] In some embodiments, two sets of mounting holes 101 for connecting to the fixing components are symmetrically arranged on the annular base 100. The mounting holes 101 are through holes, with their two ends located on the inner and outer sides of the base 100, respectively. Specifically, there are two sets of mounting holes 101, with two holes in each set. The fixing component 200 is movably connected to the base 100 through the mounting holes 101, and fastening bolts 102 are provided on the sidewalls of the mounting holes 101 to fix the fixing component 200 to the base 100. Several fixing support rods 103 for installing the protective component 300 are threadedly connected to the upper side of the base 100. In this way, the fixing support rods 103 can be separated from the base 100 when not in use, and can be threadedly connected to the base 100 when in use. An insertion hole 1031 is provided at the upper end of the fixing support rod 103 along the length direction of the fixing support rod 103 for installing the protective component 300.

[0025] In some embodiments, both the first fixing part and the second fixing part include a horizontal bar 201 and a vertical ladder 202. The vertical ladder 202 has several steps. The horizontal bar 201 is inserted into the mounting hole 101, and the length of the horizontal bar 201 inserted into the mounting hole 101 is variable. The horizontal bar 201 can slide in the mounting hole 101. One end of the horizontal bar 201 located inside the annular base 100 is integrally connected to the upper end of the vertical ladder 202. For example, the horizontal bar 201 and the vertical ladder 202 can be integrally molded from high-strength plastic, or they can be made of metal and welded together.

[0026] In some embodiments, the protective component 300 includes a plurality of enclosures, the number of enclosures corresponding one-to-one with the number of fixed support rods. Each enclosure consists of a support rod 301 and a warning shield 302. The support rod 301 includes a vertical rod 3011 and a hanging rod 3012 fixedly connected to the vertical rod 3011. The warning shield 302 is rectangular in shape, with one side of the warning shield 302 fitted onto the hanging rod 3012 and the other side hanging down.

[0027] It should be noted that the hanging rod 3012 is arc-shaped. When the enclosure is installed on the fixed support rod 103, the inner arc of the hanging rod 3012 faces the middle side of the base 100. The closer the center of the arc of the hanging rod 3012 is to the center of the base 100, the more compact the hanging rod 3012 is. The farther the center of the arc of the hanging rod 3012 is from the center of the base 100, the more extended the hanging rod 3012 is. Of course, it should be noted that the extension angle of the hanging rod 3012 should be controlled so that each hanging rod 3012 forms an approximately closed area, that is, the gap between each warning shield 302 should be controlled within a small range to prevent people from passing through the gaps.

[0028] To allow for a variable size of the manhole protection area, the end of the vertical rod 3011 furthest from the hanging rod 3012 is detachably inserted into the insertion hole 1031 at the upper end of the fixed support rod 103. The vertical rod 3011 is rotatable relative to the fixed support rod 103 to change the size of the manhole protection area formed by the enclosure. To prevent the vertical rod 3011 from rotating due to a slight breeze while inserted into the insertion hole 1031, the insertion hole 1031 has a large opening at the top that gradually narrows downwards. The portion of the vertical rod 3011 used for insertion into the insertion hole 1031 also has a conical structure to ensure proper fit. This allows the vertical rod 3011 to gradually tighten under gravity, preventing rotation even under small forces.

[0029] In some embodiments, the warning shield 302 is a reflective cloth. The upper end of the warning shield 302 forms a sleeve 3021 for fitting onto a hanging rod, and the lower end is provided with a weight block (not shown in the figure). The weight block can be hung on the lower end of the warning shield by means of a hook. Of course, the warning shield 302 can also be a sheet structure made of lightweight materials such as plastic, and the sheet structure is also set on the hanging rod in the same way as described above.

[0030] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
