Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

As shown in fig. 1 to 6, the adjustable support head for ship welding of the preferred embodiment includes a support 1, a base 2 and a positioning ring 3, wherein the support 1 includes a top plate 11 and a sleeve 12 formed on a lower end surface of the top plate 11, and an inner wall of the sleeve 12 has an internal thread.

Wherein the base 2 comprises a bottom plate 21 located below the sleeve 12 and a support column 22 formed on the upper end surface of the bottom plate 21, the support column 22 is inserted into the sleeve 12 and can move relatively in the vertical direction, and the outer wall of the support column 22 is provided with external threads, so that the support column 22 and the sleeve 12 are in threaded connection, and for the convenience of adjustment, the height of the support head is usually adjusted by moving the sleeve 12 up and down relative to the support column 22. Of course, the post 22 and sleeve 12 are not limited to threaded connections and may be removably connected by other means, such as snap-fit connections.

In addition, the support column 22 is hollow, so that the material is effectively reduced, the cost of the support head is effectively reduced, and the mass of the support head is reduced, so that the support head is convenient to carry.

Wherein the positioning ring 3 is sleeved on the support column 22 and can move up and down relative to the support column 22, in this embodiment, the inner wall of the positioning ring 3 is provided with internal threads, and the positioning ring 3 can move up to be in contact with the lower end face of the sleeve 12. When the positioning ring 3 moves to be tightly abutted against the lower end face of the sleeve 12, the positioning ring can play a role in positioning the sleeve 12, and the support 1 is prevented from moving downwards under the heavy pressure of a supported object.

In addition, the upper end surface of the positioning ring 3 is provided with a limit strip 31, the lower end surface of the sleeve 12 is provided with a limit groove 221 which is in limit fit with the limit strip 31, and the limit strip 31 can be arranged in the limit groove 221. Through spacing cooperation of spacing strip 31 and spacing groove 221 for holding ring 3 is effectual when screwing up increases the frictional resistance between holding ring 3 and the sleeve 12, thereby fixes sleeve 12 more effectively. In order to achieve better positioning effect, the spacing strips 31 are multiple and are arranged along the circumferential direction of the positioning ring 3, and the spacing grooves 221 are multiple and are arranged along the circumferential direction of the sleeve 12.

The outer circumferential wall of the positioning ring 3 is provided with a vertically extending toggle bar 32 for facilitating the rotation of the positioning ring 3, so as to facilitate the rotation of the positioning ring 3 to move up and down relative to the pillar 22.

The upper end surface of the top plate 11 is provided with an arc-shaped groove 111 with an arc-shaped vertical section for adapting to a tubular object to be supported, a protective pad 112 made of flexible materials (such as rubber) is arranged in the arc-shaped groove 111, and the protective pad 112 can prevent the arc-shaped groove 111 from being damaged. The arrangement of the arc-shaped groove 111 enables the supporting head to have a good fixing effect on the tubular object, effectively overcomes the defect that the previous supporting head has a poor fixing effect on the tubular object, and prevents the tubular object from shifting.

The radial two sides of the arc-shaped groove 111 are provided with positioning blocks 4 for preventing the supported object from separating from the arc-shaped groove 111, and the positioning blocks 4 can also play a role in supporting the supported tubular object so as to further prevent the tubular object from shifting; the upper end surface of the positioning block 4 is provided with an anti-slip sheet 41 made of flexible material (such as rubber). So make support the head when supporting the object, effectual increase object and support the frictional force between the head to the fixed effect of head to the object when supporting the object is supported in effectual reinforcing.

In this embodiment, the top plate 11 is provided with two grooves on two radial sides of the arc-shaped groove 111, and each groove is provided with one positioning block 4.

The lower end surface of the bottom plate 21 is provided with a non-slip pad 211, and the end surface of the non-slip pad 211 exposed out of the bottom plate 21 is provided with a non-slip strip 212. The effectual antiskid effect that has strengthened base 2 of slipmat 211 to the effectual frictional force that has strengthened between base 2 and the ground, thereby the effectual steadiness that supports the head that has strengthened.

In this embodiment, the base 2 and the support 1 are made of stainless steel, the stainless steel has strong corrosion resistance, and the support is made of stainless steel, so that the support head is durable and not easy to damage, and the service life of the device is prolonged effectively.

When the height of the supporting head needs to be adjusted, the sleeve 12 is rotated to axially move to a proper position relative to the pillar 22, and then the positioning ring 3 is rotated until the limiting strip 31 is limited in the limiting groove 221 of the sleeve 12.
