An assembled prefabricated road subgrade fixture

Abstract

The invention discloses a clamp for assembly type prefabricated road subgrade. The clamp for the assembly type prefabricated road subgrade comprises a first main girder, a second main girder, lifting rings, a first inserted plate, and a second inserted plate. One end of the first main girder is in movable connection with one end of the second main girder; the lifting rings are arranged on the first main girder and / or the second main girder; the first inserted plate is arranged at the other end of the first main girder, and the second inserted plate is arranged at the other end of the second main girder; the movable connection is used to adjust the length of the two ends of the first main girder and the two ends of the second main girder; the first inserted plate and the second inserted plate are arranged oppositely, and form included angles with the side surface of a clamped subgrade block downwards; a plurality of location holes are formed in the corresponding places of the first main girder and the second main girder; and the location holes are used to make the first main girder and the second main girder be connected in a relatively fixed mode. The clamp for the assembly type prefabricated road subgrade is not only applicable for subgrade blocks with different sizes, but also simple and convenient to install and use.

Description

technical field [0001] The invention relates to the technical field of hoisting equipment, in particular to an assembled prefabricated road subgrade clamp. Background technique [0002] In the field of hoisting technology, based on the need for various types of hoisting equipment, different fixtures are required to achieve hoisting of different equipment. At present, most of the hoisting equipment is directly provided with hoisting holes on the equipment, and then hoisting is realized through hoisting rings. , but for road subgrade blocks, it is not suitable to process hoisting holes on the subgrade blocks, which not only easily destroys the strength and structure of the subgrade blocks, but also for prefabricated road subgrades, most of the subgrade blocks are made of cement , It is not suitable for processing a hoisting hole with accurate size. At present, most of the hoisting of subgrade blocks needs to be hoisted with jigs, but the commonly used jigs cannot adapt to sub...

Problems solved by technology

[0002] In the field of hoisting technology, based on the need for various types of hoisting equipment, different fixtures are required to achieve hoisting of different equipment. At present, most of the hoisting equipment is directly provided with hoisting holes on the equipment, and then hoisting is realized through hoisting rings. , but for road subgrade blocks, it is not suitable to process hoisting holes on the subgrade blocks, which not only easily destroys the strength and structure of the subgrade blocks, but also for prefabricated road subgrades, most of the subgrade blocks are made of cement , it is not suitable to process the hoisting holes with accurate dimensions

At present, most of the hoisting of subgrade blocks needs to be hoisted with jigs, but the commonly used jigs cannot adapt to subgrade blocks of different sizes, and the installation and disassembly of existing jigs are inconvenient, which brings great obstacles to users.

[0003] Therefore, in the process of realizing the present invention, the inventor found that the prior art has at least the following defects: the existing clamps cannot adapt to the structure of the roadbed block, and are extremely inconvenient to use and install
