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 countable hydraulic bolt tensioner, which belongs to the technical field of tensioning equipment. It includes a stretcher main body and a counting device, the counting device is installed on the side wall of the stretcher main body, the counting device includes a connecting block and a digital counter, the connecting block is a hollow structure, and the digital counter is vertical Installed above the inside of the connecting block; the drive shaft of the digital counter is fixed with a rotating head, and a pushing mechanism is provided under the rotating head to cooperate with its rotation. The pushing mechanism is supported and installed in the connecting block and can be driven by hydraulic pressure. The up and down motion is used to push the rotating head to rotate, and a disc spring is sheathed on the outside of the pushing mechanism. Adopting the technical solution of the invention can effectively monitor the performance state of the product, prevent human misoperation from causing inaccurate counting, effectively avoid the occurrence of safety accidents during operation, and facilitate the maintenance of the tensioner.

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...
