Abstract
The invention relates to a spring type clamp, which comprises an oil cylinder, a piston, a spring seat, an isolation sleeve, a disk spring, a conical sleeve, a clamping claw, bolts, a cover board and an end cover, wherein the oil cylinder is rigidly connected with the spring seat; the piston is arranged in the oil cylinder to form a closed oil cavity; the disk spring is arranged in the spring seat; the conical sleeve is arranged outside the disk spring; the isolation sleeve is arranged in a through hole of the spring seat; one end of the isolation sleeve is tightly attached to the piston, and the other end of the isolation sleeve is tightly attached to the conical sleeve; the piston, the isolation sleeve and the conical sleeve are fastened together through the bolts; the conical sleeve is arranged between the clamping claw and the disk spring; the cover board covers the conical sleeve and the clamping claw; and the cover board and the end cover are fixed by screws. The spring type clamp is simple and rational in structure; the disk spring is used as power; the elasticity is high; the cost is low; the spring type clamp is convenient to assemble and disassemble; the pieces are connected through the bolts; the spring type clamp can be quickly disassembled and assembled without a special tool; and time can be saved.
Description
Technical field
The invention belongs to the coal mine machinery technical field, relate to a kind of rig spring clamper, 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 is adopted with the clamper of rig 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 does not just satisfy this demand.
Summary of the invention
The object of the invention 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.
According to technical scheme provided by the invention, 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 the spring base rigid connection, oil cylinder, is consisted of the oil pocket that seals with piston; The dish spring is installed in the 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 a further improvement on the present invention, described claw 7 has the identical conical surface with tapered sleeve.
Advantage of the present invention is: the present invention 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 invention.
The specific embodiment
The invention will be further described 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 of the present invention and spring base 3 rigid connection, oil cylinder 1 interior installation piston 2 consists of the oil pocket that seals with piston 2; Described dish spring abutment 3 provides support and retrains for dish spring group, and at spring base 3 interior installation dish springs 5, dish spring 5 is the kinetic energy source of clamper chucking power; The dish spring 5 outer tapered sleeves 6 that are equipped with are 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 installed in the identical draw-in groove of spring base 3 and 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 the 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 the normality.Namely dish spring 5 elastic force promote tapered sleeve 6 right laterals, do axially-movable, because 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 the piston 2 advanced pressure oil, piston 2 moved left, and pulling spacer 4 and tapered sleeve 6 move left, and the active force on claw 7 conical surfaces disappears, and unclamps drilling rod.
Spring clamper after the installation is whole, and the dish spring is consumable accessory, and is simple in structure, disassembles conveniently, and is with low cost.
