Description

Novel steel pipe anchor clamps

Technical field

The utility model relate to a kind of have a synchronous tooth can clamping and the anchor clamps of cylindrical object such as handling steel pipe, belong to the worker's accessory or the device that are used for hoisting crane, winch or coaster handling goods.

Background technology

In known technology, the anchor clamps that cylindrical objects such as handling steel pipe are commonly used, its pull bar connect with overweight boatswain chair uses the simple lay point always, and open clamp and steel pipe are direct contacts.Its weak point is anchor clamps when location hook hooks locating dowel pin or breaks away from locating dowel pin, can be around simple lay point rotation, and very inconvenient in the operation.

Summary of the invention

The later-model purpose of this reality is to avoid above-mentioned weak point of the prior art, provides a kind of pull bar that has synchronous tooth to connect with the lifting boatswain chair and adopts the multiple twin point, and be stained with the soft rubber plate at open clamp and the initial contact position of steel pipe.It is a more failure-free worker accessory of a kind of use.

The purpose of this utility model can reach by following measure: link by pins and lifting boatswain chair with the veneer pull bar of synchronous tooth with an end of two plate pull bars of synchronous tooth, an end that passes through pivot pin and center pin pivotally attached veneer clamp, two plate holder pincers of its other end links, and the other end of veneer clamp, two plate holder pincers is to be the circular arc clamping plate; The soft rubber plate is attached to the arc surface top of the circular arc clamping plate of veneer clamp, two plate holder pincers, on two plate holders pincers the clamping positioning plate is installed, and location hook is installed on the veneer pull bar with synchronous tooth, and locating dowel pin is installed on two plate holders pincers.

The utility model is compared with original technology has following advantage: a kind of pull bar that has synchronous tooth connects employing multiple twin point with the lifting boatswain chair, and be the initial contact position of open clamp and steel pipe and be stained with the soft rubber plate, can make novel steel pipe anchor clamps in whole handling labor process, can not give birth to rotation phenomenon.This steel pipe anchor clamps can be increased work efficiency, and are safe and reliable.

Description of drawings

The drawing of accompanying drawing is described as follows:

Fig. 1 is the steel pipe anchor clamps front view that is the clamping cargo state that the utility model proposes.

Fig. 2 is the steel pipe anchor clamps working diagram of the open-shaped attitude that the utility model proposes.

Fig. 3 is the left view of the steel pipe anchor clamps that the utility model proposes.

The specific embodiment

Describe in detail according to the concrete device that the utility model proposes below in conjunction with legend:

Lifting boatswain chair 1 location hook 2 clamps the two plate pull bars 10 pins 11 veneer clamps 12 of 6 locating dowel pins, 7 center pins, 8 soft rubber plates 9 with synchronous tooth with 5 pairs of plate holders of veneer pull bar 3 pivot pins, 4 clamping positioning plates of synchronous tooth

In accompanying drawing 1, load hook by steel rope, unload the gram heavy boatswain chair 1 of slinging, drive pins 11 and with the veneer pull bar 3 of synchronous tooth, with an end upward movement of the synchronous tooth of band of two plate pull bars 10 of synchronous tooth, the other end links and the while upward movement by the end of pivot pin 4 with center pin 8 pivotally attached veneer clamps 12, two plate holder pincers 6, and the circular arc clamping plate of the other end of veneer clamp 12, two plate holder pincers 6 are tightly clamped steel pipe.This moment, location hook 2 was disengaged position with locating dowel pin 7.

In accompanying drawing 2, by the steel pipe of steel pipe anchor clamps clamping behind the destination, load hook is Panasonic at a slow speed, load hook continued to descend after steel pipe landed, the lower edge of location hook 2 touches locating dowel pin 7 backs and rotates in locating dowel pin 7 enters the groove of location hook 2, be installed with on then two plate holders pincers 6 if continue to descend and clamp positioning plate 5 and contact with veneer pull bar 3 with synchronous tooth, the circular arc clamping plate of steel pipe anchor clamps can not open again.Load hook rises at a slow speed then, locating dowel pin 7 enters in the groove of location hook 2, the open-shaped steel pipe that leaves of steel pipe anchor clamps, get back to stockpile, load hook is aimed at steel pipe center Panasonic at a slow speed, soft rubber plate on the circular arc clamping plate of veneer clamp 12, two plate holder pincers 6 touches steel pipe, load hook continues to descend, contact with veneer pull bar 3 until clamping positioning plate 5 with synchronous tooth, behind the groove disengagement locating dowel pin 7 that manually makes location hook 2, load hook rises at a slow speed, picks up steel pipe until the steel pipe anchor clamps, enters next working cycle.

In accompanying drawing 3, demonstrate lifting boatswain chair 1, with the mutual alignment of members such as the veneer pull bar 3 of synchronous tooth, two plate pull bars 10, locating dowel pin 7, two plate holder pincers 6, veneer clamp 12 with synchronous tooth.
