Description

Technical Field

[0001] This application relates to the technical field of hanging ladders, and particularly to a lightweight hanging ladder for climbing a segment stack. Background Art

[0002] In related technologies, a shield segment is a special segment in shield construction, mainly used in the shield launching stage. When launching a shield, in the launching working shaft, a reaction frame (a backrest providing reaction force) is arranged at the rear end of the shield machine. An annular segment is installed between the reaction frame and the shield jacks. The shield segment provides a reverse force for the shield machine to advance through the interaction with the launching base until the shield tail of the shield mechanism enters the opening on the other side of the shaft wall.

[0003] Before and after use, shield segments need to be stacked. Usually, they are stacked in a way of standing three layers. The height of a single-layer segment is 1.5 to 1.8 meters. Buffer wooden squares with a width of 10 centimeters are used at the bottom and between layers. The highest of the three-layer segments reaches 5.7 meters. When workers carry out stacking operations, they often use an aluminum row ladder to get on and off the segment stack. During the up and down process, the outer surface of the segment is often worn due to the row ladder leaning against it, and the row ladder may also slip, causing safety accidents.

[0004] Therefore, it is necessary to design a lightweight hanging ladder for climbing a segment stack to carry out operations related to segment stacking and prevent the outer surface of the segment from being worn due to the row ladder leaning against it and the row ladder from slipping.

[0022] Segment lining needs to be stacked before and after use. Usually, it is stacked in three layers vertically. The height of a single segment lining is 1.5 to 1.8 meters. Wooden squares with a width of 10 cm are used for buffering at the bottom and between layers. The highest stack of three layers of segment linings reaches 5.7 meters. When workers carry out stacking operations, they often use aluminum ladders to climb up and down the segment lining stacks. During the up and down process, the outer surface of the segment lining is often worn due to the contact with the ladder, and the ladder may also slip, causing safety accidents.

[0023] In view of the above problems, the embodiment of the present application provides a lightweight hanging ladder for climbing segment lining stacks. It can be assembled into a hanging ladder according to the length of the segment lining through the link buckle support leg link buckle and the climbing rod link buckle. Then, with the cooperation of the hook, the hanging ladder is fixed on the segment lining, effectively avoiding the wear of the outer surface of the segment lining and the slipping of the ladder during the stacking process of the segment lining. Moreover, it adopts a splicing structure and is applicable to the stacking of segment linings of different specifications.

[0024] The technical solutions of the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0025] Figure 1 It is a schematic structural diagram of the lightweight hanging ladder for climbing segment lining stacks shown in the embodiment of the present application.

[0026] See Figure 1 , a lightweight hanging ladder for climbing segment lining stacks, including: Link buckle 1, hook 2, support leg link buckle 3 and climbing rod link buckle 4; Link buckle 1, hook 2, support leg link buckle 3 and climbing rod link buckle 4 are made of reinforced nylon material. The reinforced nylon (FR-PA) material is light in weight, wear-resistant and durable, which can avoid wearing the segment lining. There are steps with opposite directions at both ends of link buckle 1. There is a circular card slot inside the lower step of link buckle 1, and the circular card slot is divided into three parts by a stop block; there is a wedge block on the upper step of link buckle 1 that matches the circular card slot inside the lower step. The wedge block is slightly shorter than the card slot. When two link buckles 1 are spliced together, they are spliced through the card slot and the wedge block, and at the same time, a certain angle adjustment can be made; there are through holes running through the front and back on the two steps of link buckle 1. After two link buckles 1 are spliced together, a pin is installed in the through hole for fixation. Support leg link buckle 3 is composed of two link buckles 1 and a "U"-shaped pipe. The "U"-shaped pipe is composed of three square pipes. The "U"-shaped pipe is vertically installed between the two link buckles 1, and the opening of the "U"-shaped pipe faces the curved surface of the segment lining. Climbing rod link buckle 4 is composed of two link buckles 1 and a square straight pipe. The straight pipe is installed between the two link buckles 1 to form an "H"-shaped structure. Hook 2 is an "L"-shaped structure, and there is a through hole and a card slot matching link buckle 1 at one end of hook 2.

[0027] In use, the hook 2 is hung on the top of the segment. The right-angle hook is used to hold the top of the segment. Two or more link buckles 1 are spliced at the rear end of the hook 2 to connect the support leg link buckle 3. The number of link buckles 1 is adjusted according to the thickness of the segment. A certain number of climbing rod link buckles 4 are installed at the lower end of the support leg link buckle 3 through the link buckle 1. The number of climbing rod link buckles 4 is adjusted according to the length of the segment to ensure that the staff can move up and down through the climbing rod link buckle 4 and the support leg link buckle 3. A support leg link buckle 3 is also installed below the bottom climbing rod link buckle 4 for bottom support. The upper and lower support leg link buckles 3 are used to prevent the light hanging ladder from shaking.

Many modifications and variations are obvious to those of ordinary skill in the art in the technical field without departing from the scope and spirit of the described embodiments. The choice of terms used herein is intended to best explain the principles of the embodiments, practical applications, or improvements to the technologies in the market, or to enable other ordinary skill in the art in the technical field to understand the embodiments disclosed herein.
