Example Embodiment

[0019] like figure 1 As shown, in the present embodiment, nine hydraulic bolt tensioners 14 are installed in total with the auxiliary installation device for the hydraulic bolt tensioner. figure 1 The oil supply line of the hydraulic bolt tensioner 14 is not shown in the figure, which is used to fasten the fifty-four groups of bolts on the relevant equipment. The lifting ring 1 is fixed on the device through two sets of upper cover plate nuts and gaskets 3 .

[0020] like figure 2 As shown, the clamping mechanism uses two front and rear clamping plates 13 to clamp a hydraulic bolt tensioner 14, and four sets of clamping plate bolts and nuts 10 installed on the two clamping plates 13 provide clamping force. On the outer side of the splint 13 and at the geometric center of the arc section, a pin shaft 11 is installed through the interference fit of the shaft hole, and the pin shaft 11 penetrates into the waist-shaped hole 15.1 at one end of the fork-shaped structure of the co...

Abstract

The invention provides an auxiliary installation device for the hydraulic bolt tensioning jack and relates to the technical field of the fastening and disassembling of the bolt. The device comprises a clamping mechanism, a slider-guide rail mechanism and a connecting rod, wherein the clamping mechanism comprises a clamping plate, a pin, clamping plate bolts and nuts and clamp springs, the parts are used to install a plurality of hydraulic bolt tensioning jacks on the device of the invention; the slider-guide rail mechanism comprises a slider, a guide rail, an upper cover plate, a dividing disc and a stop block; and one end of the connecting rod is connected with the pin of the clamping mechanism through a waist-shaped groove, and the other end is connected with the slider of the slider-guide rail mechanism through a hinge. By adopting the device of the invention, the number of workers can be decreased, the work efficiency can be improved; by using the device, the hydraulic bolt tensioning jacks can move flexibly in the axial and circumferential directions and workers can perform the installation and positioning operations fast, accurately and intuitively; and no improvement of theexisting hydraulic bolt tensioning jack is required.

Description

technical field [0001] The invention relates to the technical field of bolt fastening and dismounting, in particular to an auxiliary installation device for a hydraulic bolt tensioner. Background technique [0002] The hydraulic bolt tensioner is a common device for fastening high-strength bolts by using a hydraulic pump to stretch the bolts to elongate them, and then easily tighten the nuts to the support surface. Multiple hydraulic bolt tensioners can be used to stretch and fasten multiple bolts at the same time. It has the advantages of compact structure, light weight, large tensile force, wide application range, high precision and fast speed. In the process of installing large-scale equipment, sometimes as many as five or sixty bolts need to be fastened, and high-quality imported hydraulic bolt tensioners are relatively expensive, and buying so many tensioners at one time will greatly increase The cost of the enterprise is unbearable for the enterprise. In fact, it is ...
