Description

Technical Field

[0001] This utility model relates to the field of underground pipeline detection manhole facilities, specifically to a tool for preventing personnel from falling into the manhole during pipeline detection construction. Background Technology

[0002] With urban development, underground pipelines are also spread all over the ground, such as drainage pipes, underground gas pipes, water pipes, power pipes, communication pipes, and defense pipes. Every so often, these pipelines have an outlet leading to the ground. This section from the pipeline to the ground is called a manhole. The manhole opening is usually flush with the ground. Underground pipeline surveys are an important technical means to understand the operating status of these underground pipelines and to carry out maintenance, planning and management. The manholes on the pipelines are important physical points for collecting pipeline information during surveys.

[0003] Collecting pipeline information through manholes requires technicians to use instruments and tools at the manhole opening on the ground to collect information about the manhole's internal properties, including measuring depth, pipe diameter, manhole chamber, manhole cover, and pipe material. This poses a risk of workers falling into the manhole. Some manholes are more than ten meters deep and connect to underground ditches or rivers. Some manholes, especially sewage wells or chemical plant manholes, may contain toxic or harmful gases. Once a person falls into a manhole, the narrow confines of the shaft make rescue extremely difficult, posing a significant safety hazard to human life. Therefore, it is necessary to adopt technical measures to prevent manhole accidents.

[0004] Currently, the methods used to prevent people from falling into wells in the pipeline detection and construction field are to require employees to enhance their safety awareness, increase the number of personnel for vigilance, or tie safety ropes to the construction workers. These methods are difficult to fundamentally eliminate the safety hazard of falling into wells or are simply not feasible in the construction environment around the manhole (such as tying safety ropes).

[0005] With the accelerated construction of underground pipeline networks nationwide and the increased maintenance work on pipelines, the workload of pipeline survey and detection is also increasing. How to avoid the risk of pipeline survey and construction personnel falling into wells is an urgent issue to be addressed. Utility Model Content

[0006] To address the aforementioned safety hazard of falling into manholes, this utility model provides a safety manhole-shaped tool for preventing falls during underground pipeline detection manhole construction, thus solving the problem of construction workers falling into manholes in existing methods.

[0007] Technical solution:

[0008] The present invention relates to a safety well-shaped tool for preventing falls during underground pipeline detection and manhole construction, comprising a well-shaped frame body, a reinforced skeleton, a tool storage and release buckle, an anti-slip pin, and an anti-slip pad.

[0009] The main body of the grid frame includes four reinforced aluminum alloy square tubes and four movable vertical shafts. The length of the tubes is determined according to the diameter of the manhole opening, generally between 80-100 cm, and is divided into two specifications. The four aluminum alloy square tubes are connected by four movable vertical shafts. During use, the four vertical shafts form a square, and the horizontal and vertical spacing between the shafts is 30-40 cm. The length of the four reinforced movable shafts is adjustable.

[0010] The main skeleton components are connected by movable axes, and based on these movable axes, the main skeleton components can exist in two states:

[0011] State 1: The skeletons are stored in parallel.

[0012] State 2: The skeleton is in a grid-like configuration during use;

[0013] The retractable buckle consists of two components, which are fixed to two opposite main frames. One end of each component is inserted into the main frame and moves freely around the inserted end as a pivot. The other end is inserted into the opposite main frame, so that the retractable buckle and the two adjacent main frames are fixed in a triangle to ensure the stability of the safety grid tool body in use.

[0014] The aforementioned encrypted skeleton is connected to two pipe fittings of the grid frame. Both ends of each encrypted skeleton are inserted into the pipe fittings of the grid frame body. The application of the encrypted skeleton is optional, depending on the physique of the construction personnel.

[0015] The encrypted skeleton is fixed to the main skeleton by a hook;

[0016] The encrypted skeleton is made of metal;

[0017] The aforementioned tool retraction buckle is to prevent the fall protection tool from being accidentally retracted during use, which could cause accidental injury to construction workers. The fall protection buckle is placed diagonally on the projection surface of the main body of the well frame. One end of the buckle is connected to a square pipe of the well frame and can move freely, but cannot be removed. The other end is inserted into a small hole on another square pipe when in use. After use, it is removed from this end and retracted with the main body of the well frame. The retraction buckle at the other diagonal end is the same.

[0018] The anti-slip pins consist of four six-pointed star-shaped rubber-headed Torx screws with pointed tips, which can be freely screwed in and out of the four main body sections of the grid frame. The four anti-slip pins are placed at the top of the four pipes of the grid frame, and screw holes are provided at corresponding positions on the main body frame. Each anti-slip pin can be freely screwed in and out of the main body frame. The anti-slip pads consist of four rubber sleeves with high friction, which are respectively fitted into the ends of each main body frame to prevent the anti-fall safety grid tool from sliding freely when used on relatively smooth surfaces.

[0019] In its normal state, the fall-prevention safety grid tool is folded up in a straight line. When in use, it is unfolded into a grid shape and placed above the manhole being worked on. The tool's retraction latch is then secured to prevent accidental unfolding during use. Four anti-slip pins are screwed in, ensuring the four pointed ends are firmly against the ground to prevent slippage. This allows workers standing near the manhole to easily collect data such as pipeline surveys and manhole information. In the event of a fall, the unfolded grid shape can catch the person, and the worker can also grab any of the four fittings, providing an extra layer of safety.

[0020] Beneficial effects of this utility model

[0021] This utility model relates to an active fall-prevention safety manhole cover, which uses minimal materials, is sturdy and practical, and is easy to store and carry. When in use, it is placed on top of the manhole opening, thus avoiding the risk of workers falling into the manhole without interfering with work inside. It features low operating costs, economic feasibility, simple operation, and convenient portability, making it suitable for field pipeline surveys and construction. Attached Figure Description

[0025] The present invention will be further described below with reference to embodiments, but the scope of protection of the present invention is not limited thereto:

[0026] like Figure 1-3 As shown, the safety grid tool for preventing falls during underground pipeline detection manhole construction includes: the main body of the safety grid tool 1, the retraction buckle 2, the optional reinforced safety tool frame 3, the anti-slip pin 4, and the anti-slip pad 5;

[0027] The fall-prevention safety grid tool body 1 consists of four frames, forming a fall-prevention safety structure. The four frames are connected by four movable shafts. The fall-prevention safety tool retraction buckle 2 consists of two components, fixed to two opposite main frames. One end of each component is inserted into the frame, allowing free movement, while the other end is inserted into the opposite frame. When in use, the two components and the two main frames form an "X" shape to prevent accidental injury from accidental retraction. The encrypted frame consists of two metal materials, each fixed to the same main frame at one end, allowing free movement, while the other end is inserted into the corresponding main frame during use. The application of the encrypted frame improves fall-prevention safety. The anti-slip pins 4 consist of four pointed devices with plum blossom-shaped handles, placed near the top of two of the four main frames. Each anti-slip pin can be freely screwed in and out of the main frame. The anti-slip pads 5 consist of four high-friction leather cylindrical objects, nested at the top of the two main frames that are grounded.

[0028] In actual operation: From such Figure 2 With the device stowed, open the underground pipeline detection manhole safety cross tool in a "well" shape. Place it on top of the manhole opening during the pipeline survey, and then... Figure 3 The rotating tool is used to retract the locking buckle, causing the other end of the buckle to engage with one of the main frame components with anti-slip pads. The object's locking buckle is operated in the same way. The buckle's function is to prevent accidental retraction of the fall protection tool during use, which could cause injury. After the buckle is engaged, if the manhole is located on a soil surface, the anti-slip pins 5 on the two main frame components in the grid pattern should be screwed in one by one, so that the tips of the four anti-slip pins grip the ground, preventing the fall protection tool from slipping off the manhole opening and causing an accident. If the manhole is located on a hard surface such as cement or smooth asphalt, the four anti-slip pads on the main frame are sufficient. The final step is to connect the two reinforced frames to the opposite tool main frame. Two reinforced frames can be selected according to the actual situation, or one can be used.

[0029] After the safety grid tool for underground pipeline detection manhole construction is in place, construction workers can safely collect the necessary data and perform other operations around the manhole using instruments and tools. If an accidental fall occurs during the work process, the safety grid tool will prevent the construction workers from falling into the manhole. Even if part of their body falls into the manhole, as long as they hold onto any part of the safety grid tool with both hands, they will be prevented from falling further. Because of the safety tool's locking and releasing function, the safety grid tool will not twist or deform and fall into the manhole, but instead becomes a barrier to protect lives.

[0030] After a well is completed, first remove the reinforced frame 3, then put away the snap-fit ​​buckle 2, and then put away the safety well tool in a straight line. Depending on the ground conditions of the manhole being constructed, select the anti-slip pin 4 or anti-slip pad 5.

[0031] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
