Description

Rocker arm type complete tool for fixing fishing line and fixing method thereof

Technical Field

The invention relates to the field of cultural relic protection, in particular to a rocker arm type complete tool for fixing a fishing line and a fixing method thereof.

Background

Museums are important places for collecting, researching, displaying and transmitting human cultural history and scientific and cultural knowledge, and are important bases for storing and maintaining cultural relics in museums. China is a large history culture country and numerous cultural relics. According to the data display of the first nationwide movable cultural relic census, as soon as 2016, 5, 18 and 14481 registered collection units in the nationwide movable cultural relic information registration platform log in 48592662 cultural relics (18413268 cultural relics/set). A large number of movable cultural relics are collected and stored in a museum, cultural relic display and daily maintenance management are facilitated, but the risk of large-scale damage of the cultural relics under sudden disasters is increased, and particularly, the natural disasters such as earthquakes which are seriously damaged are more and more, people feel more and more free and insufficient. Therefore, how to protect the cultural relics from being damaged in the earthquake and minimize the damage to the cultural relics caused by the earthquake should be the most important of the museum work.

In recent years, China frequently occurs earthquake, and a large number of cultural relics in the collection of the cultural relics are damaged. For example, 14 hours at 12 months and 12 days in 2008, 28 minutes and 04 seconds, 8.0-level Lishi earthquake occurs in Wenchuan and North China in Sichuan, which causes 2766 collected cultural relics in City of 7 provinces (city) such as Sichuan, Gansu, Shaanxi and the like to be damaged, wherein 292 precious cultural relics are included.

The cultural relics can adopt a certain method to resist the damage of the earthquake due to the strength, the rigidity or the flexibility of the cultural relics, thereby achieving the purpose of protection. The application of anti-seismic measures to cultural relics by foreign museums is common, and high-strength new materials are often generated in the anti-seismic protection of the museums in the United states, such as the American san Francisco Asia art museum, and each cultural relic displayed is fixed by a special metal bracket and other materials; cultural relics displayed in the Taibei Imperial palace are fixed by using a thin nylon wire in a precise measuring and calculating way; in the exhibition hall of the national museum of Kyoto Japan, part of the ceramics in the showcase are firmly fixed on the bottom support by transparent nylon wires, and the parts of the nylon wires, which are contacted with cultural relics, are sleeved with transparent plastic hoses; many units and expert scholars in China also carry out relevant research on earthquake-resistant measures of the exhibition-laid cultural relics, for example, in 1976, under the support of the national cultural relics office and earthquake-resistant offices in the Jingjin area of the national institute of construction and Commission of Japan at that time, 10 earthquake-resistant measures such as a gravity center descending method, a cementation method, a nylon hasp, a magnet method, an internal support method and the like are taken for 41 cultural relics of the Story museum, and tests are carried out on a vibration table, so that the cultural relics of the Story museum can be almost undamaged in the Tangshan earthquake of 1976.

The fish line ligature is one of the measures commonly used in museum historical relic exhibition, but the position of fish line ligature and the difference of ligature dynamics have directly influenced the effect of ligature, for example: the binding position is not proper, and the cultural relics cannot be guaranteed not to fall down; the cultural relics can be damaged by stress concentration under static force or dynamic force if the binding force is too large, and the protective effect cannot be achieved fundamentally if the binding force is not enough; moreover, ineffective banding may also create false images to the custodian, paralyze the mind during improper deployment, and cause damage to the cultural relics.

As shown in fig. 1, the invention is a schematic diagram of a fish line binding mode, which is a schematic diagram of a fish line binding commonly used in a museum, because the binding strength directly affects the safety of cultural relics, the binding strength should be quantified in the binding operation process, otherwise, the binding strength is too large, if the cultural relics are fragile, the cultural relics may be damaged, and when the binding strength is not enough, the function of preventing the cultural relics from overturning cannot be achieved. The cultural relics 8 bound by the fishing lines 4 are usually matched with the clamping feet 9 for use, and the clamping feet 9 are firmly fixed on the exhibition support 5 by adopting the modes of bonding or tack fixing and the like. In the case of the exhibition effect permission, preferably, a soft cushion layer or a soft cushion pipe and the like can be added at the position where the fishing line 4 contacts the cultural relic 8.

As shown in fig. 2, the rocker arm type kit for fixing fishing line and the fishing line binding and fixing method thereof of the present invention include an operating tool, a consumable tool and a fixing member 3, wherein the operating tool is a rocker arm 1, and the consumable tool is a disc clamp 2. Disc anchor clamps 2 are fixed in the exhibition through mounting 3 and hold in the palm 5 on, rocking arm 1 is connected with disc anchor clamps 2, holds in the palm disc anchor clamps 2 on 5 by 1 drive of rocking arm, and it is taut to setting for the internal force value and fixed with fish tape 4.

As shown in fig. 3, the rocker arm 1 has a rocker 11, a rocker sleeve 12 and a force control switch 13, the rocker 11 of the rocker arm 1 is in a zigzag structure, and the cross section of the rocker 11 is cylindrical; a straight handle at one end of a rocker 11 of the rocker arm 1 is sleeved with a rocker sleeve 12, the section of the rocker sleeve 12 is a circular ring concentric with the straight handle of the rocker 11, and the rocker sleeve 12 can rotate relative to the axis of the straight handle of the rocker 11; the rocker 11 is made into a Z shape and mainly plays a role in accelerating the rotation of the disc clamp 2, and the purpose of enabling construction to be faster is achieved by the principle similar to a speed changing vehicle. One end of the rocker 11, which is close to the disc clamp 2, is defined as a rocker front section 111, one end of the rocker 11, which is connected with the rocker sleeve, is defined as a rocker rear section 112, a force control switch 13 is arranged at an elbow joint between the rocker front section 111 and the rocker rear section 112, the force control switch 13 keeps a closed state when the rocker 11 bears a small force, the rocker 11 can drive the disc clamp 2 to rotate, and the section of the front end part of the rocker front section 111 is a polygonal section; when the set force is reached, the force control switch 13 is turned on, so that the rear section 112 of the rocker cannot drive the front section 111 of the rocker to rotate, the effect similar to tripping is achieved, and the purpose that the disc clamp 2 does not rotate no matter how the rocker rotates is achieved. The basic definition of the force control switch is as follows: the force control switch 13 directly controls the rocker 11, and when the rocker 11 bears a small force, the rocker 11 keeps a closed state, and the rocker 11 can drive the disc clamp 2 to rotate; when the set force is reached, the force control switch 13 is turned on, so that the rear section 112 of the rocker cannot drive the front section 111 of the rocker to rotate, which is similar to the tripping effect, for example, in fig. 3, the force control switch 13 is turned on, and the upper side is conveniently turned but 11 is not rotated; its function is similar to a torque wrench in construction. The force control switch 13 can be realized by intelligent control or by mechanical means. If the intelligent control mode is adopted, the method can be as follows: when the force sensor reaches the judgment condition, the rocker sleeve 12 is rocked at will, but the rocker 11 does not rotate, and the control is realized through a computer or a chip, namely a certain starting condition is set through a program, the rocker drives the disc clamp to start when the rocker is smaller than the set force, and after the set force is reached, the rocker sleeve 12 idles but the rocker 11 is static. If the device is a mechanical device, the device can be: when a certain force is reached, the pin is broken or the bolt is tripped, so that the rocker sleeve 12 can be conveniently rocked but the rocker 11 does not rotate.
