Embodiment 1

[0034] A countable hydraulic bolt tensioner in this embodiment includes a tensioner main body and a counting device, and the counting device is installed on the side wall of the tensioner main body through a set bolt 11 . Such as Figure 3-6 As shown, the counting device includes a connection block 1 and a digital counter 5, the connection block 1 is a hollow structure, and the digital counter 5 (the existing 5-digit rotary counter on the market can be used) is installed vertically inside the connection block 1 above, for counting. Such as Figure 5 As shown, the rotating head 4 is fixedly installed on the driving shaft 501 of the digital counter 5, and a pushing mechanism is provided under the rotating head 4 to cooperate with its rotation. The pushing mechanism is supported and installed in the connecting block 1, and can Drive to move up and down, and the pushing mechanism moves upwards through the oil supply of the oil cylinder, so that the rotating head 4 drives the dri...

Abstract

The invention discloses a hydraulic bolt stretcher capable of counting times, and belongs to the technical field of stretching equipment. The hydraulic bolt stretcher comprises a stretcher main body and a time counting device, wherein the time counting device is mounted on the side wall of the stretcher main body; the time counting device comprises a connecting block and a digital counter; the connecting block is of a hollow structure; the digital counter is vertically mounted above the inner part of the connecting block; a rotary head is fixedly mounted on the drive shaft of the digital counter; a pushing mechanism which is rotatably matched with the rotary head is arranged below the rotary head; the pushing mechanism is supported and mounted in the connecting block, and can be driven byoil pressure to move up and down to push the rotary head to rotate; and a disc spring further sleeves the pushing mechanism. With the adoption of the technical scheme of the invention, the hydraulic bolt stretcher can effectively monitor a performance state of a product, prevents manual mis-operation to cause inaccurate time counting, effectively avoids occurrence of a safety accident in operation, and is convenient for repair and maintenance of the stretcher.

Description

technical field [0001] The invention belongs to the technical field of tensioning equipment, and more specifically relates to a countable hydraulic bolt tensioner. Background technique [0002] Hydraulic bolt tensioner is called hydraulic tensioner for short. It has the functions of bolt fastening and disassembly, and can be widely used in metallurgy and mining, petrochemical, shipbuilding, power system, rolling stock, heavy machinery and other industries. With the help of the hydraulic power provided by the ultra-high pressure pump, the hydraulic tensioner uses the elastic range allowed by the material to stretch the bolt in its elastic deformation zone to achieve the purpose of fastening or removing the bolt. [0003] At present, the service life of the hydraulic tensioner in the industry is generally 8,000 times, and its performance needs to be monitored by counting during use, so as to avoid safety accidents during operation. Most of the existing hydraulic tensioners do...
