Abstract
The utility model relates to a spring type clamping machine which comprises an oil cylinder, a piston, a spring seat, a spaced sleeve, a butterfly-shaped spring, a conic sleeve, a jack catch, a bolt, a cover plate and an end cover. The oil cylinder and the spring seat are connected in a rigid mode. The piston is installed in the oil cylinder. A closed oil cavity is formed through the piston and the oil cylinder. The butterfly-shaped spring is installed inside the spring seat. The conic sleeve is installed outside the butterfly-shaped spring. The spaced sleeve is arranged in a through hole in the spring seat. One end of the spaced sleeve is attached to the piston tightly and the other end of the spaced sleeve is attached to the conic sleeve tightly. The piston, the spaced sleeve and the conic sleeve are fixed together through the bolt. The conic sleeve is arranged between the jack catch and the butterfly-shaped spring. The cover plate seals the conic sleeve and the jack catch inside. The cover plate and the end cover are fixed through a screw. The spring type clamping machine is simple and reasonable in structure design, large in elasticity due to the fact that the butterfly-shaped spring is used as motive power, low in cost and convenient to assemble and disassemble. Each component is connected through the bolt so that disassembly and assembly can be achieved rapidly without special tools, and therefore time is saved.
Description
Technical field
The utility model belongs to the coal mine machinery technical field, relates to a kind of rig spring clamper, and specifically a kind of use spring provides end thrust, utilizes the conical surface to be converted into the radially clamper of chucking power.
Background technology
Hydraulic clamp with the clamper of rig, is adopted in the colliery now.This hydraulic gripper, chucking power is large, but when rig cut off the power supply, hydraulic system quit work, and chucking power also just disappears.Under some operating mode, when rig cuts off the power supply, still need to have whole enough chucking powers to exist, hydraulic gripper just can not meet this demand.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that existing wagon drill clamper exists, provide a kind of structure ingenious rationally, disassemble conveniently, install rapidly, stable performance, low cost of manufacture, the clamping ability is strong, and can improve the spring clamper of rig utilization rate.
The technical scheme that provides according to the utility model, described spring clamper comprises oil cylinder, piston, spring base, spacer, dish spring, tapered sleeve, claw, bolt, cover plate and end cap, piston is installed in described oil cylinder and spring base rigid connection, oil cylinder, is consisted of with piston the oil pocket that seals; The dish spring is installed in described spring base, and the dish spring is equipped with tapered sleeve outward, and spacer is installed in the through hole of spring base, and spacer one end is close to piston; The other end is close to tapered sleeve, and bolt tightens together piston, spacer, tapered sleeve; Between claw and dish spring, tapered sleeve is housed, in cover plate was enclosed in tapered sleeve, claw, cover plate, end cap were screwed.
As further improvement of the utility model, described claw 7 has the identical conical surface with tapered sleeve.
Advantage of the present utility model is: the utility model is simple and reasonable, adopts the dish spring as power, and elastic force is large, and cost is low; Easy accessibility is used Bolt Connection between each part, does not need special tool just can disintegrate rapidly and installation, can save time.
Description of drawings
Fig. 1 is STRUCTURE DECOMPOSITION figure of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in Figure 1, comprise oil cylinder 1, piston 2, spring base 3, spacer 4, dish spring 5, tapered sleeve 6, claw 7, bolt 8, cover plate 9, end cap 10 and screw 11.
Oil cylinder 1 described in the utility model and spring base 3 rigid connection, the interior installation piston 2 of oil cylinder 1 consists of with piston 2 oil pocket that seals; Described dish spring abutment 3 provides support and retrains for dish spring group, and at the interior installation dish of spring base 3 spring 5, dish spring 5 is the kinetic energy source of clamper chucking power; The outer tapered sleeve 6 that is equipped with of dish spring 5 is installed spacer 4 in the through hole of spring base 3, spacer 4 limits the relative position of piston and tapered sleeve; Spacer 4 one ends are close to piston 2; The other end is close to tapered sleeve 6, and tapered sleeve 6 passes to claw to power by the dish spring, and the dish spring is also played effect of contraction; Bolt 8 tightens together piston 2, spacer 4, tapered sleeve 6; Claw 7 is arranged in spring base 3 draw-in groove identical with end cap 10, at claw 7 and 5 of dish springs, tapered sleeve is housed, and in cover plate 10 was enclosed in tapered sleeve 6, claw 7, described claw 7 had the identical conical surface with tapered sleeve, clamps drilling rod under the driving of tapered sleeve.Cover plate 9 is fastened on spring base 3 with screw 11 for the closure plate of clamper with end cap 10.
Whole clamper is the normally closed type structure, namely is the clamping attitude under normality.Namely dish spring 5 elastic force promote tapered sleeve 6 right laterals, do axially-movable, and due to conical surface effect, tapered sleeve 6 promotes claw 7 and does radial motion, the chucking drilling rod; When the cavity between oil cylinder 1 and piston 2 advanced pressure oil, piston 2 moved left, pulled spacer 4 and tapered sleeve 6 to move left, and the active force on claw 7 conical surfaces disappears, and unclamps drilling rod.
Spring clamper after installation is whole, and the dish spring is consumable accessory, and is simple in structure, disassembles conveniently, and is with low cost.
