Definitions
- the invention relates to a device for introducing translatory forces and / or torques into movable bodies with the aid of clamping jaws which grip the body.
- Knives are often used to securely transmit the clamping forces to the movable bodies, with which the clamping jaws are fitted.
- the knives or other elements which considerably increase the local surface pressure often damage the surfaces of the rigid bodies to be moved or lead to undesired impressions, so that the damaged body surfaces are increasingly exposed to corrosion.
- stainless steel is increasingly being used for borehole pipes at ⁇ Ife Idtechni k. For this reason, a long service life is important for cost reasons.
- the invention is based on the object of designing a device according to the generic term mentioned at the outset in such a way that damage-free attack of the clamping jaws on the surfaces of the bodies to be detected and moved is made possible.
- the solution according to the invention is characterized in that the clamping jaws are equipped with inserts made of elastomeric material as a carrier material for a large number of hard particles with tips directed against the contact surfaces of the bodies to be clamped.
- the invention enables the transmission of large translational forces or large torques directed perpendicular to the clamping forces to rigid bodies to be moved without damaging their surfaces and thereby subjecting them to increased corrosion, largely independently of the material used. Bodies made of plastic can also be detected without disadvantage. This advantage is achieved by a wide-area, combined friction and form fit, the elasticity of the carrier material ensuring full-area contact between the insert and the surfaces to be detected even if the latter has an exact flat or cylindrical shape soft and, for example, areas of greater or lesser unevenness or curvatures.
- the ends of the needles on the attack side extend essentially up to the surface of the insert lying against the body to be moved, while the ends of the needles on the clamping jaw side are preferably at a distance from the contact surface of the elastomeric inserts on the clamping jaws end up.
- the elastomeric material located between the needle ends on the jaw side and the jaws can compensate for unevenness in the parts to be clamped, since elastomeric material can flow laterally at high pressure.
- Crystal grains of the same or different sizes made of diamond, glass, corundum, quartz, ceramic and the like are suitable for this.
- Fig. 1 shows the cross section through a tube with this
- FIG. 3 shows an enlarged view of a region of the longitudinal section AB
- FIG. 4 shows the enlarged plan view of a part of the insert with embedded needle-shaped parts
- FIG. 5 shows the arrangement of needle-shaped parts with an inclination to the radial direction
- FIG. 6 shows the enlarged representation of a longitudinal section of an insert with embedded granular particles
- FIG. 7 shows the cross section through a tube clamp with inserts with embedded needle-shaped parts
- FIG. 8 shows a longitudinal section through the tube clamp according to FIG. 7 and FIG. 9 individual parts of the tube clamp in a diagrammatic representation.
- a pipe section 1 of a clamping jaw 2 which consists of a clamping body 3 and a jaw shell 4 for receiving an insert 5 made of an elastomeric material.
- the * clamping body 3 shows hinge-like fastening tabs 3a between which the tabs of lever-like holding elements (not shown) engage, which are secured by the bores 6 by inserting a bolt.
- the shell 4 forms together with the surface of the tube 1, the sti rnsei ti gene end rings 7 and longitudinal strips 8 a chamber for receiving the deposits 5th
- the insert 5 made of elastomeric material contains radially aligned needles 9, the radially outer ends of which end at a distance in front of the jaw shell 4.
- the elastomeric material 10 in this area therefore has the possibility, in the event of unevenness of the parts to be screwed, being displaced laterally under high pressure and to compensate for the unevenness.
- needles 11 with an inclination to the radial direction are embedded. Their course shows a discontinuity 11a in the form of a kink in the radially outer region, which leads to a radially directed region.
- the needles are better able to move sideways if this is necessary due to the not completely uniform surfaces on which the insert lies.
- the needles are designed to be resilient.
- Metals based on iron and non-iron can be mentioned as suitable materials for the needles.
- Needles made of plastic of sufficient hardness are also conceivable. These can lead to a particularly gentle treatment of the surfaces to be detected when high torques are transmitted. With all rod-shaped parts, excessive deflection or kinking is prevented by the all-round pressure of the carrier material.
- the elastomeric material of the insert 5 contains granular particles 12, for example diamond dust grains.
- granular particles 12 for example diamond dust grains.
- Other critical materials are suitable, such as quartz, glass, corundum, ceramics and the like.
- the inserts 5 can collectively encompass an encircling angle of almost 360 °, so that only slight d. H . schli z-shaped spaces 13 arise that the contact pressure to ensure adequate • must be available.
- the surface pressure can be determined by the length of the inserts, so that inserts can be manufactured, the surface pressure of which corresponds to the respective pipe material.
- the insert comprising the tube 20 is divided into three segments 21a to 21c. Each segment is positively fastened in a multi-part adapter 23a to 23c.
- the adapters 23a to 23c are positively connected to keys 26a to 26c via dovetail-shaped grooves 24 and correspondingly designed springs 25.
- End rings 27 and longitudinal strips 28 form chamber-shaped receiving spaces for the inserts 21 with their rigid shells 22 on the adapter elements 23.
- the deposits are thus secured against rotation as well as against displacement in the longitudinal direction.
- the wedges 26 lie with their outer jacket surfaces in a wedge-shaped opening 32 of a housing ring of the entire pipe clamp. Due to the weight of the pipe string 30 in the direction of the pipe 31, all the elements involved in the pipe clamp slide into one another and hold the pipe string at the upper end of the pipe string after loosening an elevator, without the outer casing of the pipe string being cut or indented knife-like tools is damaged.
