Description
Technical Field
The invention relates to the technical field of underground equipment and facility maintenance and pit construction operation equipment, in particular to a novel plug-in type ladder stand installed in a ground well.
Background
The ground well is a passage leading from the ground to an underground power cable tunnel and a municipal pipe network pipe gallery, and mainly comprises a power cable, water supply and drainage, fuel gas, a communication optical cable, pit construction and the like.
At present, in projects such as domestic underground power cable tunnels, pipe network pipe gallery maintenance and pit construction, the crawling ladder in the ground well is used as a tool for a ground and shaft bottom channel, is mainly used for connecting the ground and a downhole working surface, and provides a safety channel for constructors, wherein the ground and the shaft bottom can reciprocate.
Among the prior art, the cat ladder welding in the ground well is in the well head below, and its appearance size is fixed can not be adjusted, and constructor takes place easily when going into the well because look inaccurate foot ladder and step on empty dangerous condition, therefore causes the injury to the human body, so await the improvement.
Disclosure of Invention
The invention aims to improve the safety of the well descending construction and solve the problem that a constructor is not easy to find a ladder to step on the ground when descending the well, so that personal injury is caused by improving the structural design.
In order to achieve the purpose, the invention provides a vertical main ladder which is provided with vertical rods at two sides and a middle cross brace, wherein the top ends of the vertical rods at two sides of the vertical main ladder are provided with inserting ports which are respectively connected with the bottom ends of the vertical rods at two sides of an auxiliary ladder in an inserting and detachable mode; the auxiliary ladder further comprises a cross rod used as a pedal between the vertical rods at the two sides, and hooks respectively fixed at the two sides of the vertical rods and used for hooking the top end inserting port of the main ladder.
In an optimal mode, the auxiliary ladder and the main ladder are respectively connected with the corresponding vertical rod and the vertical rod through two metal chains.
In a preferred mode, the inserting port is a square hole; the vertical rods are square tubes.
Preferably, holding devices are arranged on two sides of the main ladder.
The invention has the advantages that: the auxiliary ladder is inserted into the main ladder, so that the part above the well is increased by the ladder stand in the well, the underground operation of constructors is facilitated, and the personal safety of the constructors is effectively ensured.
The ladder stand is low in manufacturing cost, the structural strength and the performance of the ladder stand are not changed after the ladder stand is spliced and lengthened, the maintenance is simple and easy, the disassembly and the assembly are convenient, and the investment and the maintenance cost in the production construction are effectively reduced.
Drawings
Fig. 1 is a schematic view of the present invention with a ladder hanging state.
Fig. 2 is a schematic diagram of the main ladder and the auxiliary ladder in a splicing state.
Fig. 3 is a disassembled structure view of the main ladder and the auxiliary ladder of the present invention.
In the figure, 1, a wellhead, 2, a vertical rod, 3, a cross brace, 4, a main ladder, 5, a plug interface, 6, an auxiliary ladder, 7, a vertical rod, 8, a cross rod, 9, a hook, 10, a metal chain, 11, a holding device and 12, a well wall prefabricated part are arranged.
Detailed Description
As shown in fig. 1-3, the plug-in type ladder stand structure installed in the ground well comprises a detachable auxiliary ladder 6 above a well mouth 1, a main ladder 4 fixed on the well wall in the well mouth 1, square tube vertical rods 2 and a middle cross brace 3 arranged on two sides of the main ladder 4, the main ladder 4 is welded on a well wall prefabricated part 12, and the well wall prefabricated part 12 is embedded on the well wall. When the auxiliary ladder is used, the auxiliary ladder 6 and the main ladder 4 are fixedly integrated in the height direction in an inserting mode through the square inserting ports 5, and the auxiliary ladder 6 further comprises a cross rod 8 serving as a pedal between the vertical rods 7 of the square pipes on two sides. The two sides of the main ladder 4 are provided with holding devices 11, and the safety of constructors can be guaranteed by holding the holding devices 11 when the constructors go into the well.
When not in use, attach ladder 6 and be in the state of hanging, attach 6 both sides vertical pole 7 top of ladder and be equipped with two couples 9 respectively, can will attach ladder 6 and hang on interface 5 through couple 9, attach ladder 6 and main ladder 4 and still connected corresponding vertical pole 7 and vertical pole 2 through two metal chain 10 respectively, will attach ladder 6 and be connected with main ladder 4 to attach ladder 6 and drop when preventing the couple fracture.
The plug-in type cat ladder of installation in the ground well just can make it install in all kinds of ground wells such as electric power facility and municipal facilities very conveniently through suitably reforming transform it according to different operational environment, has eliminated the construction hidden danger effectively, has ensured construction safety.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered as the equivalent or modified within the technical scope of the present invention disclosed in the present invention, the technical solution of the present invention and the inventive concept thereof are covered by the scope of the present invention.
