Abstract
The utility model provides a hydraulic type nut clipper which is particularly applicable to wellhead devices under a working condition that fire and electricity are not permitted to use. The nut clipper comprises a connection plate, an active scissors body provided with a supporting weighted arm and an active work head, and a passive scissors body provided with a passive weighted arm and the passive work head, wherein, the active scissors body and the passive scissors body are respectively hinged with the connection plate through backing pins; a clamping part for nuts to be clipped is formed between the active work head and the passive work head; a blade is mounted on the active work head through a connecting piece; a cylinder body provided with a hydraulic oil cavity and an oil-taking pipeline inside the hydraulic cylinder is fixed on the supporting weighted arm of the active scissors body; the first end of the piston rod is inserted into the cylinder body and integrated with a piston; and the second end extending out of the cylinder body is in contact with the passive weighted arm. The nut clipper can cut off nuts quickly and efficiently, the screw rod can not be damaged, and the use is safe.
Description
Technical field:
The utility model is a kind of the nut that spanner can't be blocked because of corrosion, modification to be broken the special tool(s) of cutting dismounting, is applicable to that especially oil well head device etc. does not allow with the fluid pressure type nut clipper under the working condition of fiery electricity consumption.
Background technology:
At present, in chemical industry equipment, be extensive use of nut and fix plant equipment, can not block, nut can't be dismantled owing to ubiquitous reasons such as corrosion, modification cause spanner.Especially the dismounting of the equipment of chemical industry, requirement must be operated not having fire and do not have under the situation of electricity, so the mode that can not adopt oxygen welding to cut off is dismantled, makes troubles for the maintenance, replacing etc. of equipment, and equipment is stopped production.
The utility model content:
The purpose of this utility model is that nut is difficult for or non-detachable problem in order to solve, provide a kind of and fast and efficiently nut cut off, and do not damage screw rod, the fluid pressure type nut clipper of safety.
The purpose of this utility model is achieved like this:
The utility model fluid pressure type nut clipper, comprise connecting plate, respectively by the hinged band of backing pin and connecting plate support be subjected to the arm of force and initiatively working head the active scissor body, with the passive passive scissor body that is subjected to the arm of force and passive working head, form between main, passive working head and wait to cut the nut clamping part, initiatively by connector blade is housed on the working head, the band hydraulic fluid chamber in the hydraulic jack and the cylinder body of in-line are fixed on initiatively that the support of scissor body is subjected on the arm of force, and piston rod first end stretches in the cylinder body second end that is integral with piston and stretches out cylinder body and contacts with passive stressed wall.
Pad is equipped with by connector in the position of the blade on the above-mentioned passive working head on the relative initiatively working head.
On the above-mentioned backing pin back-up ring is housed, prevents that connecting plate from separating with master, passive scissor body.
The oil connection that is communicated with in-line is arranged on the above-mentioned cylinder body, be connected with hydraulic power system fast.
Be positioned at the compressing member that is fixed with band U type groove between two backing pins by screw on the above-mentioned connecting plate, briquetting is arranged in U type groove, between briquetting and U type groove one wall steel wire is arranged, the screw threaded one end passes another cell wall of U type of compressing member and presses closer on briquetting, and that the two ends of steel wire are embedded in respectively is main, in the caulking groove on the passive scissor body.
The blade peace that is fit to be cut the nut size is stuck in the driving knife work, the utility model is connected with hydraulic power system, the nut that needs are sheared is placed on to be waited to cut in the nut clamping part, the operation hydraulic power system, pressurization produces broken shear force to nut thereby promote piston rod by hydraulic jack, is broken fully until nut.
The utility model volume is little, easy to operate, favorable working performance, under conditions such as other limited space of high-altitude, manpower, on-the-spot non-transformer, all can adopt manual hydraulic power unit, the broken ability of cutting is strong, nut is cut off at a high speed, soon with cutting, and do not damage screw rod, can not produce spark, safety is applicable to various fire prevention, explosion-proof field.
Description of drawings:
Fig. 1 is this fluid pressure type nut clipper overall structure schematic diagram.
The specific embodiment:
The utility model fluid pressure type nut clipper comprises connecting plate 1, supports being subjected to the arm of force 3 with the active scissor body 5 of active working head 4, with the passive passive scissor body 8 that is subjected to the arm of force 6 and passive working head 7 respectively by the hinged band of backing pin 2 and connecting plate.Form between main, passive working head and wait to cut nut clamping part 9.Main, passive working head opposite position is equipped with blade 10, pad 11 by screw respectively.The band hydraulic fluid chamber 13 in the hydraulic jack 12 and the cylinder body 16 of in-line 14 are fixed on initiatively, and the support of scissor body is subjected on the arm of force.Piston rod 17 first ends stretch in the cylinder body and piston 18 is integral and stretch out cylinder body second end and passive stressed arm contact.The oil connection 19 that is communicated with in-line is arranged on the cylinder body.Back-up ring 20 is housed on the backing pin.Be positioned between two backing pins the compressing member 22 that is fixed with band U type groove 21 by screw on the connecting plate, being arranged between the briquetting 23 of U type groove and U type groove one wall has steel wire 24, and screw 25 threaded one ends pass another cell wall of U type of compressing member and press closer on briquetting.That the two ends of steel wire are embedded in respectively is main, in the caulking groove 26,27 on the passive scissor body.
At first measure the specification of nut 15, choose with the blade 10 of this nut coupling and pacify on the active working head 4 that is stuck in the active scissor body, the oil pipe with oil connection 19 and hydraulic power system is connected then.The nut 15 that will need brokenly then to cut is clamped on the clamping part 9.Open hydraulic power system and make hydraulic oil enter hydraulic fluid chamber 13 to promote pistons 18 and piston rod 19 motions, and then promote passively to be subjected to the arm of force 6 and support outwards opened by the arm of force 3 by oil pipe and oil connection 19.Backing pin 2 is a fulcrum, is subjected to the arm of force to make active working head 4 and passive working head 7 to nut 15 motions under the effect of backing pin 2, make blade 10 press to nut gradually, and strength is increasing, is broken fully until nut.Pressure-relief valve on the last operation hydraulic power system makes system's release.
