Abstract

The utility model discloses a large-tonnage multi-cylinder type anchorage-cable stretching tool which comprises a hydraulic pump, an anchorage-cable clamping utensil, a hydraulic cylinder and a hydraulic pipeline, wherein the hydraulic pump and the hydraulic cylinder are communicated by the hydraulic pipeline, and the clamping sheets of the clamping utensil on the hydraulic cylinder clamp an anchorage cable; the number of oil cylinders ranges from 2 to 8, and the oil cylinders are arranged and connected in parallel; oil pipes used for equalizing the pressure forces of all oil cylinders are arranged among pipelines of the hydraulic pump and the oil cylinders; the oil cylinders and the anchorage-cable clamping utensil are arranged side by side and are fixed through connecting plates. When the large-tonnage multi-cylinder type anchorage-cable stretching tool is additionally loaded by a prestressing force, the anchorage cable is uniformly stressed, a stretching force is greater and the length of the tool is shorter. Secondly, because the oil cylinders which are additionally loaded can be made into standard components, by that different number of oil cylinders are combined, different stretching forces can be exerted. Again, because the anchor device of the stretching tool is used as a replaceable standard component, when anchorage cables in different specifications are stretched, only corresponding clamping sheets of the clamping utensil need to be assembled for replacement. The utility model has the advantages of convenient operation, and strong adaptability to the anchorage cables. The utility model is used for mine support and building trades.

Description

Large-tonnage multiple casing anchorage cable stretching facility
Technical field
The utility model relates to a kind of large-tonnage multiple casing anchorage cable stretching facility.
Background technology
At present, anchor cable prestressed stretch-draw facility are mainly single casing.The anchor cable anchor clamps are connected with oil cylinder.The weight of single casing tensioner own is big, and length is longer, and the space that needs is also bigger, is difficult to realize the large-tonnage stretching force to anchor cable.And its anchor cable compliance to different-diameter is not strong, and a kind of tensioner can only carry out prestressing force to a kind of anchor cable of diameter and load, and uses inconvenient.
Summary of the invention
The purpose of this utility model is to provide a kind of large-tonnage multiple casing anchorage cable stretching facility for overcoming above-mentioned weak point.Because large-tonnage multiple casing anchorage cable stretching facility are arranged evenly along circumference that by a plurality of oil cylinders anchor cable is stressed even when carrying out the prestressing force loading, stretching force is big, so facility length is reduced, it is less to take up room, and helps downhole operations.
A kind of large-tonnage multiple casing anchorage cable stretching facility comprise hydraulic pump, anchor cable anchor clamps, hydraulic cylinder and fluid pressure line, by fluid pressure line hydraulic pump and hydraulic cylinder are communicated with; Anchor clamps intermediate plate on the hydraulic cylinder is clipped on the anchor cable; The quantity of oil cylinder is 2-8, is arranged in parallel between each oil cylinder; Be provided with the oil pipe of balanced each oil cylinder working-pressure between adjacent two oil cylinders; Each oil cylinder and anchor cable anchor clamps are set up in parallel and fix by junction plate.
Described anchor cable anchor clamps are provided with 3-4 anchor clamps intermediate plate of same specification.
Described hydraulic pump is manual pump or air driven pump or electrodynamic pump.
Anchor cable was stressed even when large-tonnage multiple casing anchorage cable stretching facility carried out the prestressing force loading, and stretching force is big, and facility length is reduced, and it is little to take up room, and helps carrying out execute-in-place.Secondly, because load cylinder can be made standard component, crudy is easy to guarantee, can realize the stretching force of different size by the combination of varying number oil cylinder.Once more, the anchor clamps intermediate plate of going up correspondence gets final product because this tensioner ground tackle as an independent removable standard component, only need change the outfit during stretch-draw different size anchor cable, and is easy to use, thereby the multiple casing tensioner has very strong compliance to anchor cable.
Description of drawings
Fig. 1 is large-tonnage multiple casing anchorage cable stretching facility schematic diagrames;
Fig. 2 is the hydraulic cylinder schematic diagram;
Fig. 3 is the hydraulic cylinder lateral view.
The specific embodiment
Further specify the utility model below in conjunction with drawings and Examples.
Large-tonnage multiple casing anchorage cable stretching facility are made up of hydraulic pump 1, pressure meter 2, hydraulic cylinder 3, two oil circuit designs, and the oil cylinder quantity of present embodiment is 3, hydraulic pump adopts manual pump, hydraulic cylinder is connected by high-pressure rubber pipe with hydraulic pump, and pressure meter is received on the oil circuit, so that observe on-load pressure.Referring to Fig. 1.Hydraulic cylinder comprises that terminal pad 6, piston 7, snap joint 8, cylinder body 9, anchor clamps intermediate plate 10, hydraulic cylinder connect oil pipe 11 and junction plate 12.Referring to Fig. 2.Terminal pad is made as equilateral triangle, and three oil cylinders are distributed on three angles of the same circumference of equilateral triangle.Referring to Fig. 3.Between adjacent two oil cylinders, be provided with the connection oil pipe, with the pressure of balanced each oil cylinder.Three cylinder blocks and anchor cable anchor clamps are by being set up in parallel and linking together by junction plate.Pistons end is fixed on the terminal pad.The anchor cable anchor clamps of present embodiment are provided with three anchor clamps intermediate plates, and evenly distribute along circumference.
Allow anchor cable 4 pass hydraulic cylinder anchor cable anchor clamps during work earlier, arrange the position, the handle wrench of reversal valve 5 to loading position, is added to press to by hydraulic pump and injects hydraulic oil in the oil cylinder, promote piston motion, the anchor clamps intermediate plate clamps anchor cable in the piston motion process.The loading force value shows that by pressure meter the pressure gauge reading of observing hand oil pump changes, and stops to load when reaching the regulation prestress value.To meta, hydraulic cylinder unloads with the reversal valve handle wrench, simultaneously the work anchor automatic locking of oil cylinder front portion.Do not mark among the work anchor figure.When moving back anchor, by the direction of reversal valve change oil circuit, piston moves in the other direction, in piston returns to cylinder body.The anchor clamps intermediate plate is subjected to top power to unclamp anchor cable therebetween.Hydraulic cylinder can be taken off from anchor cable, this root anchorage cable stretching finishes.
