Abstract
Description
Technical Field
[0001] The utility model relates to a special hanging device for coffin wood, belonging to the technical field of archaeological excavation auxiliary tools. Background Art
[0002] Tomb culture has a long history in my country and is an important part of our country's cultural history. It not only reflects the splendor of Chinese civilization, but also becomes a window for modern people to understand history. A large number of precious cultural relics unearthed from tombs fully demonstrate the historical development and characteristics of the times. Many local governments will build some site parks or select museums to simulate and restore the tomb sites according to the tomb conditions for people to visit.
[0003] At present, during the excavation and protection of tombs, due to the limitations of the on-site environment and equipment, workers usually use cranes to assist in excavation; for example, the coffin chamber of the Zenghouyi Tomb is built with giant rectangular catalpa wood (coffin wood). The weight of a single coffin wood is so huge that it is impossible to remove it one by one manually. Therefore, it must be lifted by a crane to facilitate subsequent anti-corrosion, reinforcement, and repair. However, since the lifting rope between the crane hook and the coffin wood is gradually reduced in the shape of a "∧" from bottom to top, the narrow part of the lifting rope directly contacts the coffin wood, causing damage to the outer surface of the coffin wood. On the other hand, since the unearthed coffin wood is highly saturated with water and has different degrees of decay, the direct use of slings is not only inconvenient to tie the slings; there is also a risk of the coffin wood breaking during the lifting process, so it is necessary to improve it. Summary of the invention
[0004] The utility model aims to provide a special sling for coffin wood which is convenient to use for sling tying and can effectively prevent the coffin wood from being damaged or broken.
[0005] The technical solution of the utility model is:
[0006] A special lifting device for coffin wood includes a lifting rod, a lifting rope and a bearing member, wherein a plurality of lifting ropes are arranged on the lifting rod, and one end of the lifting rope is movably connected to the bearing member; the characteristic is that the lifting rod is in the shape of an elongated strip, and lifting rings are symmetrically arranged on the top of the lifting rod, and lifting hoops are installed between the lifting rings through pull ropes, and a plurality of adjustment holes are evenly distributed on the lifting rod below the lifting rings, and the lifting ropes are arranged at intervals between the adjustment holes, and the lifting ropes are in a "herringbone" shape, and one end of the lifting rope is connected to the adjustment hole through a movable buckle, and a hook is fixedly installed on the other end of the lifting rope, and the lifting rope is movably connected to the bearing member through the hook.
[0007] Support rods are arranged between the slings.
[0008] Locking pieces are respectively arranged at both ends of the support rod.
[0009] The described carrier is composed of multiple carrier units connected together. The carrier unit is a frame body in the shape of a Chinese character "mu". A backing plate is fixedly installed on the upper surface of the carrier unit. Locking members are symmetrically arranged on the outer sides of both ends of the carrier unit. The sling is movably connected to the carrier through a hook. Connecting ear plates with fixing holes are symmetrically arranged at one end of the carrier unit for the mutual connection between carrier units.
[0010] The described locking member is composed of an assembly plate, a locking screw, a locking nut and a locking plate. The assembly plate is fixedly installed on the outer side of the carrier unit through a tightening screw. Locking screws are symmetrically installed on the assembly plate, and a locking plate is installed on the locking screw through a locking nut.
[0011] The described carrier is a rectangular plate body. Hoisting ear holes are symmetrically arranged on both sides of the carrier. Adjusting holes are regularly arranged on the carrier between the hoisting ear holes. Limiting plates are symmetrically and movably installed in the adjusting holes to radially limit the coffin wood to be hoisted.
[0012] The beneficial effects of the present utility model are as follows:
[0013] The special sling for coffin wood has a simple structure and good practicability. The carrier is composed of multiple carrier units connected together, so that the overall length of the carrier can be adjusted, thereby adapting to the hoisting of coffin woods of different lengths. Through the support rod arranged between the slings, it effectively avoids the problem that the existing hoisting ropes are in a gradually shrinking shape of "∧" from bottom to top, and the narrow part of the hoisting rope directly rubs against the coffin wood, resulting in damage to the outer surface of the coffin wood. On the other hand, locking members are symmetrically arranged on the outer sides of both ends of the carrier unit. The locking members can form a locked state for the hoisting ropes, effectively avoiding the situation that the hoisting ropes slip during the transfer process, and is particularly suitable for the transfer work of coffin woods.

Detailed implementation manners Embodiment 1
[0022] The special sling for the inner and outer coffins includes a suspension rod 1, a suspension cable 2 and a carrier 3. The suspension rod 1 is in a long strip shape. Sling rings 4 are symmetrically arranged at the top of the suspension rod 1. A suspension band 5 is installed between the sling rings 4 through a pull rope for connecting with the hook of a crane. A plurality of adjustment holes 6 are evenly distributed on the suspension rod 1 below the sling rings 4, and multiple groups of suspension cables 2 are arranged at intervals between the adjustment holes 6. The suspension cables 2 are in a "person" shape; support rods 7 are arranged between each group of suspension cables 2 to prevent the suspension cables 2 from contacting the inner and outer coffins during work and forming friction to damage the inner and outer coffins. One end of the suspension cable 2 is connected with the adjustment hole 6 through a movable buckle 14, and a hook is fixedly installed at the other end of the suspension cable 2. The suspension cable 2 is movably connected with the carrier 3 through the hook.
[0023] The carrier 3 is formed by connecting a plurality of carrier units. The carrier unit is a frame body in the shape of "eye"; a backing plate 8 is fixedly installed on the upper surface of the carrier unit; locking members 9 are symmetrically arranged on the outer sides of both ends of the carrier unit. The suspension cable 2 is movably connected with the carrier unit through the hook; connecting ear plates 10 with fixing holes are symmetrically arranged at both ends of the carrier unit for the mutual connection between the carrier units. The connecting ear plates 10 at both ends are arranged in a staggered manner to ensure that the connecting ear plates 10 can form a fit during the connection process between the carrier units.
[0024] The locking members 9 at both ends of the support rod 7 and the locking members 9 on the outer sides of both ends of the carrier unit are respectively composed of an assembly plate 11, a locking screw 13, a locking nut and a locking plate 12. The assembly plate 11 is fixedly installed on the outer side of the carrier unit and (or) both ends of the support rod 7 through fixing screws. Locking screws 13 are symmetrically installed on the assembly plate 11, and a locking plate 12 is installed on the locking screw through a locking nut. During work, the locking members 9 at both ends of the support rod 7 clamp the suspension cable 2 through the assembly plate 11 and the locking plate 12, thereby realizing the fixation of the support rod 7 between each group of suspension cables 2, so that each group of suspension cables 2 forms a spread state, avoiding the suspension cables 2 from contacting the inner and outer coffins and forming friction to damage the inner and outer coffins. During the hoisting process, the hook at the bottom end of the suspension cable 2 is hooked on the locking screw 13 between the assembly plate 11 and the locking plate 12, which can prevent the hook from slipping off during the hoisting process.
[0025] When the special lifting device for coffin wood is used at the archaeological site, the coffin wood is first placed on the bearing member 3 by means of a lifting shovel (excavation tool), and then the hook at the bottom end of the sling 2 is hooked on the locking screw 13 between the assembly plate 11 and the locking plate 12, and the crane is started to lift the coffin wood out of the tomb pit, and this cycle is repeated to complete the lifting work of all the coffin wood (see attached figure). Figure 1-5 ). Example 2
[0026] The special lifting device for the coffin wood includes a lifting rod 1, a lifting rope 2 and a bearing member 3. The lifting rod 1 is in the shape of a long strip, and lifting rings 4 are symmetrically arranged on the top of the lifting rod 1. A lifting hoop 5 is installed between the lifting rings 4 through a pull rope, which is used to connect with the hook of the crane. There are multiple adjustment holes 6 evenly distributed on the lifting rod 1 below the lifting ring 4, and multiple groups of lifting ropes 2 are arranged at intervals between the adjustment holes 6. The lifting rope 2 is in the shape of a "human"; a support rod 7 is arranged between each group of lifting ropes 2 to prevent the lifting ropes 2 in the same group from contacting the coffin wood during work, causing friction and damaging the coffin wood. One end of the lifting rope 2 is connected to the adjustment hole 6 through a movable buckle, and the other end of the lifting rope 2 is fixed with a hook. The lifting rope 2 is movably connected to the bearing member 3 through the hook.
[0027] The bearing member 3 is a rectangular plate body, and hoisting ears 15 are symmetrically arranged on both sides of the bearing member 3. Limit adjustment holes 16 are regularly arranged on the bearing member 3 between the hoisting ears 15. The limit plate 17 is symmetrically and movably installed on the bearing member 3 through the limit adjustment holes 16, so as to radially limit the coffin wood to be hoisted during operation to prevent the coffin wood from sliding on the bearing member 3. The limit plate 17 is a rectangular plate body, and the bottom of the limit plate 17 is provided with insertion teeth 18 corresponding to the limit adjustment holes 16. The limit plate 17 is movably inserted on the bearing member 3 through the cooperation of the insertion teeth 18 and the limit adjustment holes 16 (see the attached Figure 6-7 ).
[0028] When the special lifting device for the coffin wood is used at the archaeological site, the coffin wood is first inserted between two stacked coffin woods by means of a lifting shovel (excavation tool) or a wooden crossbow, so that a prying gap is formed between the upper and lower coffin woods, and then the bearing member 3 is inserted along the prying gap. After the bearing member 3 is inserted along the prying gap, the limiting plate 17 is inserted into the adjusting hole 16 of the bearing member 3 close to both sides of the coffin wood, thereby forming a limited fixation for the coffin wood to prevent the coffin wood from sliding on the bearing member 3 during the lifting work; after the above preparations are completed, the hook at the bottom end of the sling 2 is hooked on the lifting ear holes 15 on both sides of the bearing member 3, and the crane can be started to lift the coffin wood out of the tomb pit, and the cycle is repeated to complete the lifting work of all the coffin woods. During the lifting process, the number of bearing members 3 to be inserted can be selected according to the length of the coffin wood. The special lifting device for coffin wood has a simple structure and good practicality. Through the support rod 7 arranged between the lifting ropes, it effectively avoids the problem that the existing lifting rope gradually shrinks in a "∧" shape from bottom to top, and the narrow part of the lifting rope directly rubs against the coffin wood, thereby causing damage to the outer surface of the coffin wood. It is particularly suitable for use in the transportation of coffin wood.
