Description

Technical Field

[0001] The utility model relates to a maintenance shaft structure which uses a well cover as a support frame, and is applicable to the technical field of shaft equipment. Background Art

[0002] In some power plants, factories or workshops, there are usually maintenance shaft structures. Under normal conditions, the shaft opening is covered by a cover plate so as not to affect the normal passage of personnel or vehicles. When some parts or equipment in the shaft need to be maintained, the cover plate of the opening is temporarily opened, and then the operators enter from the opening of the shaft and climb down along the ladder provided on the side wall of the shaft to reach the designated working position. However, the commonly used simple cover plate at present can only play a basic covering role. When the cover plate is opened and the personnel go down the shaft for operation, due to the lack of a reliable grip at the opening of the shaft, the operators can only slowly bend down and use the ground as an auxiliary support, and then step on the ladder on the side wall of the shaft to slowly go down the shaft, or temporarily set up a support frame at the opening of the shaft as an auxiliary support. The above methods all have inconvenience and danger. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is: To solve the above technical problem, the utility model provides a maintenance shaft structure which uses a well cover as a support frame.

[0004] The technical solution adopted by the utility model is: A maintenance shaft structure which uses a well cover as a support frame, characterized in that: it has a shaft main body, a well cover is arranged at the top of the shaft main body, a ladder is arranged along the length of the shaft main body on the inner wall of the shaft main body, a clamping groove is made at the top of the shaft main body, the well cover can be inserted into the clamping groove along the length direction of the shaft main body, and a handrail is installed on the well cover. In this way, when the well cover covers the shaft main body, the handrail is inside the shaft. When personnel need to go down the shaft for operation, by removing the well cover from the opening of the shaft main body and inserting it into the clamping groove of the shaft main body, the handrail on the well cover is exposed and located at the position corresponding to the ladder in the shaft main body. In this way, when personnel go down the shaft for operation, the handrail plays an auxiliary support role. The operators hold the handrail on the well cover and step on the ladder in the shaft, making it more convenient and safe to climb down or climb up the shaft.

[0005] A clamping groove matched with the well cover is made at the top of the shaft main body. In this way, when the well cover is closed on the shaft main body, by matching the well cover with the clamping groove on the shaft main body, it is convenient to install the well cover on the shaft main body, and at the same time, the movement of the well cover is restricted, thereby preventing the well cover from falling into the shaft main body from the top.

[0006] A handle is installed above the manhole cover. The handle is connected to the manhole cover through a rotating shaft, and an installation groove for cooperating with the handle is made on the manhole cover. In this way, when the manhole cover is closed on the main shaft body, the handle on the manhole cover is above the manhole cover, and the handle can rotate to the position of the installation groove under the action of the rotating shaft, and the handrail on the manhole cover is below the manhole cover, avoiding forming a protrusion on the manhole cover to trip pedestrians.

[0007] The beneficial effect of the present utility model is that by arranging a handrail on the manhole cover, it is convenient to open the manhole cover arranged on the main shaft body and insert it into the card slot of the main shaft body when it is necessary to use the inspection shaft. At this time, the handrail on the manhole cover is located at the position corresponding to the step ladder in the main shaft body, which is convenient for personnel to use the handrail on the manhole cover as a support when going down the well for operation, facilitating the personnel to go down the well for operation.

[0012] The present utility model will be further described in detail below in conjunction with the drawings and through embodiments. The following embodiments are explanations of the present utility model, and the present utility model is not limited to the following embodiments.

[0013] This embodiment is a structure of an inspection shaft using the manhole cover 2 as a support frame.

[0014] In this embodiment, there is a main shaft body 1, and step ladders 1-1 are uniformly installed on the inner wall of the main shaft body 1 along the length direction of the main shaft body 1, so as to facilitate personnel to go down the well for operation through the step ladders 1-1.

[0015] In this embodiment, a manhole cover 2 is arranged at the top of the main shaft body 1. Among them, a card installation groove 1-3 is made at the top position of the main shaft body 1, and the card installation groove 1-3 cooperates with the manhole cover 2. In this way, when the inspection shaft is not in use, the manhole cover 2 is placed on the top of the main shaft body 1, and under the cooperation of the manhole cover 2 and the card installation groove 1-3 at the top of the main shaft body 1, it can prevent the manhole cover 2 from slipping or even falling from the top of the main shaft body 1.

[0016] In this embodiment, a clamping groove 1-2 is formed at the top of the shaft main body 1. The manhole cover 2 can be inserted into the clamping groove 1-2 along the length direction of the shaft main body 1. A handrail 2-1 is installed on one side of the manhole cover 2 facing the inside of the shaft main body 1. In this way, when the inspection shaft needs to be used, by opening the manhole cover 2 and inserting it into the clamping groove 1-2 of the shaft main body 1, at this time, the handrail 2-1 on the manhole cover 2 is exposed and located at a position corresponding to the stairway 1-1 inside the shaft main body 1. When personnel go down the well for operation, it is convenient for personnel to support their bodies by holding the handrail 2-1 on the manhole cover 2 and cooperating with the stairway 1-1 inside the shaft main body, which is convenient for personnel to go down the well for operation.

[0017] In this embodiment, a handle 2-2 is installed on the side of the manhole cover 2 facing away from the shaft main body 1. The handle 2-2 is connected to the manhole cover 2 through a rotating shaft, and an installation groove 2-3 cooperating with the handle 2-2 is formed on the manhole cover 2. In this way, when the inspection shaft does not need to be used, the handle 2-2 on the manhole cover 2 rotates into the installation groove 2-3 to prevent the handle 2-2 from protruding on the manhole cover 2 and tripping pedestrians; when the inspection shaft needs to be used, the handle 2-2 can be rotated outside the manhole cover 2, thus facilitating the use by personnel.

[0018] The operation method of this embodiment is as follows:

[0019] Personnel hold the handle 2-2 arranged in the installation groove on the manhole cover 2 and rotate the handle 2-2 outward from the manhole cover 2;

[0020] Personnel operate the handle 2-2 to rotate and lift the manhole cover 2 along one side, so that the manhole cover 2 rotates to a position corresponding to the clamping groove 1-2 on the shaft main body 1;

[0021] Clamp the manhole cover 2 in the clamping groove 1-2 on the shaft main body 1. At this time, the handrail 2-1 on the manhole cover 2 is at a position corresponding to the stairway 1-1 inside the shaft main body 1;

[0022] When personnel go down the well, the handrail 2-1 on the manhole cover 2 can be used as a support frame.

[0023] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
