Abstract
A piston remover for a ZL50F type loader pincer type brake-shoe includes: a nut 2, a support sleeve 3, a lead screw 4, a conical slide block 5 and a cone 6, and is characterized in that the piston remover for the ZL50F type loader pincer type brake-shoe is a rod member structure; external threads are arranged on the upper and lower parts of the lead screw 4; a hole 1 is disposed on the upper end of the lead screw 4; the cone 6 is screwed with the lower end of the lead screw 4; the cylindrical movable conical slide block 5 composed of three pieces is provided with a boss on the lower part of the excircle and is internally provided with a conical hole chamber matched with the cone 6; a through hole is disposed in the center of the upper bottom of the cylindrical support sleeve 3; the lead screw 4 penetrates through the through hole; the nut 2 is screwed into the lead screw 4 for fixing the support sleeve 3. The utility model has advantages of simple structure, and convenient operation, is labor-saving and time-saving, greatly improves the operation efficiency, decreases the labor intensity of the maintenance staff, effectively shortens the equipment maintenance time, increases the equipment serviceability rate and guarantees the normal production in oil field.
Description
One, technical field
The utility model relates to the jaw type brake-shoe special tool for service technology of the field operation ZL50F type loading machine of oil, gas industry, particularly is a kind of ZL50F type loading machine jaw type brake-shoe piston extractor.
Two, background technology
Be responsible for the ZL50F type loading machine of site operation grasping operation goods at present in the oil field, its brakes is a caliper disc, and brake-shoe is the jaw type brake-shoe.Owing to work in the environment of mire for a long time, brake-shoe is worked in the immersion of be everlasting earth and rainwater.Brake-shoe is the operative minor that hydraulic cylinder and piston are formed.Because the condition of work very severe, the hydraulic cylinder of brake-shoe and piston often break down and need repairing.Yet the piston of brake-shoe often bonds together because of corrosion and hydraulic cylinder, and maintenance does not have specific purpose tool again, takes out very difficulty of piston.The traditional method of maintenance brake-shoe has two kinds: the one, and adopt hammer to knock brake-shoe, utilize the principle of object inertia impact, by knocking brake-shoe, make and do relative motion between piston and the hydraulic cylinder that piston slowly shifts out, and finally breaks away from hydraulic cylinder.On average need 30 minutes ability to take out a piston, working strength of workers is very big, wastes time and energy.The 2nd, take on the brake-shoe parent boring, machining screw box, and then be screwed into bolt, eject piston from the back side of piston.But the brake-shoe parent needs the hydraulic cavities of good seal parent through after holing.Adopt screw plug to carry out shutoff, poor effect, often poorly sealed because of this screw plug, cause the ZL50F type loading machine can't operate as normal, finally cause brake shoe assembly to scrap.Therefore, prior art can not solve the problems of the technologies described above preferably.
Three, summary of the invention
The utility model has designed a kind of ZL50F type loading machine jaw type brake-shoe piston extractor for solving the problems of the technologies described above, and takes out difficult problem to solve ZL50F type loading machine jaw type brake-shoe piston.
ZL50F type loading machine jaw type brake-shoe piston extractor comprises: nut, support set, leading screw, conical sliding block, cone; It is a member structure, has external screw thread on the leading screw, and the upper end of leading screw is provided with the hole, so that penetrate crowbar, cone is threaded with the leading screw lower end; The cylindrical movable conical sliding block that three lobes are formed, the cylindrical bottom is provided with a boss, so that tangle piston cavity, piston is taken out, and inside is provided with the tapered bore that cooperates with cone; There is a through hole at the upper base center of cylindrical shape support set, and leading screw therefrom passes, and screws in leading screw by nut support set is fixed.
ZL50F type loading machine jaw type brake-shoe piston extractor according to such scheme is made has characteristics simple in structure, easy to operate, time saving and energy saving, rapidly and efficiently.Particularly the maintenance of equipment time has effectively been shortened in the significantly raising of operating efficiency and the significantly reduction of maintenance personal's labour intensity, improves the serviceability rate of equipment, has ensured the ordinary production in oil field.
Four, description of drawings
Fig. 1-the utility model The field schematic diagram.
The plan structure schematic diagram of conical sliding block 5 among Fig. 2-Fig. 1.
In the accompanying drawing, 1-hole, 2-nut, 3-support set, 4-leading screw, 5-conical sliding block, 6-cone, 7-piston, 8-cylinder sleeve, the 9-pump housing, 10-oil duct.
Five, the specific embodiment
Below in conjunction with accompanying drawing enforcement of the present utility model is further elaborated:
The utility model comprises: nut 2, support set 3, leading screw 4, conical sliding block 5, cone 6; Its integral body is member structure, has external screw thread on the leading screw 4, and the upper end of leading screw 4 is provided with hole 1, and cone 6 is threaded with leading screw 4 lower ends; The cylindrical movable conical sliding block 5 that three lobes are formed, the cylindrical bottom is provided with a boss, and inside is provided with the tapered bore that cooperates with cone 6; There is a through hole at the upper base center of cylindrical shape support set 3, and leading screw 4 therefrom passes, and screws in leading screw 4 by nut 2 support set 3 is fixed.
Method of operating: at first,, put into brake-shoe piston 7, contact with the brake-shoe bottom with leading screw 4 and cone 6 combinations; Secondly, three cone slide blocks 5 are put into piston 7 one by one, fit together with cone 6; The 3rd, support set 3 is placed on the brake-shoe pump housing 9, allow screw mandrel 4 pass from the centre bore of support set 3; The 4th, the top of nut 2 from screw mandrel 4 screwed in, fit until nut 2 and support set 3 upper bottom surfaces, insert the upper end hole 1 of screw mandrel 4 with crowbar, firmly rotate nut 2 with spanner, realize moving on cone 6 progressively the annular groove position of piston 7, cone slide block 5 radially opens automatically, boss skids off on the inner groove that is stuck in piston 7, has realized the locking of cone slide block 5 with piston 7; Continue rotation nut 2, progressively piston 7 is shifted out from cylinder sleeve 8.
