Description

Concrete pipe pile mould's stone tongs

Technical Field

The utility model belongs to the technical field of concrete pipe pile production technique and specifically relates to a stone tongs of concrete pipe pile mould.

Background

In the prior art, the concrete pipe pile mould has large overall weight, and is hoisted by a travelling crane, and a clamping jaw mechanism is connected to a lifting steel wire rope of the travelling crane and used for clamping a connecting rib on the pipe pile mould to realize hoisting. However, in the practical use process, the height of the travelling crane is generally about 3-5 m, the lifting steel wire rope is difficult to align the connecting ribs after hanging the clamping jaw mechanism down, manual supporting operation is needed, but a travelling crane driver is positioned at the top and is far away, so that the operation of a supporting worker below the travelling crane is dangerous, and safety accidents are easy to occur.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the not enough of above-mentioned technique and providing a stone tongs of concrete tubular pile mould can realize finely tuning the accuracy of connecting in order to promote with the relative position of the splice bar of tubular pile mould to the claw arm.

In order to achieve the purpose, the hoisting clamp for the concrete pipe pile mould comprises a travelling crane and two lifting steel wire ropes on the travelling crane, wherein two claw arms are arranged on each lifting steel wire rope, the claw arms are arranged in a crossed manner, a pin shaft is arranged at the crossed position of the middle parts of the two claw arms, opposite claw hooks are arranged on the inner sides of the lower ends of the two claw arms, the end parts of the lifting steel wire ropes are connected with the end parts of the claw arms through two branch ropes, and the claw hooks are used for clamping connecting ribs on the pipe pile mould; a horizontal threaded sleeve is fixedly connected to the end portion of the pin shaft, a lead screw is arranged in the threaded sleeve, connecting seats are arranged at two ends of the lead screw, the connecting seats are rotatably connected with the lead screw, a first motor is arranged on one of the rotating seats, the first motor is in transmission connection with the lead screw, a base is arranged below each connecting seat, the base and the connecting seats are connected through a screw and a screw sleeve, a second motor is arranged in the base, the second motor is in transmission connection with one of the screw and the screw sleeve, the other part of the screw and the screw sleeve is fixedly connected with the connecting seat, and an electromagnet is arranged at the bottom of the base; a tension spring is arranged between the top end of one claw arm and the lower end of the other claw arm.

In the technical scheme, the power supplies of the first motor, the second motor and the electromagnet can be connected through a wire by a power supply on the travelling crane, and the electric vehicle further comprises a controller, wherein the controller is used for controlling the actions of the first motor, the second motor and the electromagnet. In the specific use process, a driver of a crane basically makes claw arms on two lifting steel wires close to a connecting rib of a pipe pile die to be connected according to actual judgment, then controls a second motor to act to extend between a screw rod and a screw rod sleeve, so that the claw arms are positioned on the pipe pile die and are contacted with the pipe pile die when the pipe pile die is contacted, an electromagnet is started to adsorb a base on the pipe pile die, then a first motor acts to drive a screw rod to rotate, a threaded sleeve drives the claw arms to move on the screw rod to correspond to the positions of the connecting rib, simultaneously, under the action of a tension spring, claw hooks of the two claw arms are opened, so that the two claw hooks are positioned on two sides of the connecting rib, the second motor acts to contract the length between the screw rod and the screw rod sleeve, after the claw arms are lowered to proper positions, the lifting steel wires of the crane are raised, the upper ends of the two claw arms are drawn together, so that the two claw hooks, the connection is stable and firm, and then the electromagnet is powered off. The position of the claw arm can be automatically finely adjusted without being supported by personnel, and the reliability and the safety are improved.

The utility model provides a stone tongs of concrete tubular pile mould, it can effectively realize the convenience and the stability of claw arm to the centre gripping of tubular pile mould through reasonable structural design, and the security is higher in the production process.
