Description

Semicircle board hoist

Technical Field

The utility model relates to a lifting accessory, in particular to a semicircular plate lifting appliance.

Background

The self-elevating drilling platform is one kind of main equipment for shallow sea petroleum drilling, and is composed of three to four piles and one operation platform with drilling machine, power, equipment, residence and other equipment. When drilling, the platform lifting transmission device is used for lifting the operation platform to a certain height from the sea level along the pile leg to start drilling operation, after drilling is completed, the platform lifting device is firstly used for lifting the operation platform to the water surface to enable the operation platform to float, then the pile leg is lifted, the drilling platform is towed to a new well position by the towing wheel, and then the pile leg is lowered, and the operation platform is lifted to start a new round of operation.

The spud leg of the self-elevating drilling platform is a key core component for elevating the large-scale self-elevating drilling platform. The pile leg is formed by welding a plurality of string pipes and a supporting frame, and each string pipe is formed by welding a rack and two semicircular plates. The processing of the semicircular plate directly influences the welding quality of the chord tube. The semicircular plate is required to be subjected to working procedures such as pressing, straightening, correcting, beveling, sawing, end processing and the like, and hoisting operation is required to be carried out in each working procedure.

Disclosure of Invention

The utility model aims to provide a semicircular plate lifting appliance, which solves the problem that the lifting appliance is difficult to grasp a semicircular plate in the prior art.

The utility model comprises the following steps: two hoist components of a whole that can function independently, hoist components of a whole that can function independently includes: the two lifting appliance components of a whole that can function independently are connected together through at least one connecting device front and back symmetry, have a connecting device to be equipped with the hoist ring.

The connecting device is a pin shaft.

The first pin shafts are connected between the corresponding connecting rod hinging positions on the two hanger components, and the second pin shafts and the third pin shafts are also connected between the hinging positions of the two connecting rods and the clamping rods on the two hanger components.

And a hoisting ring is arranged on a first pin shaft connected between the corresponding connecting rod hinging positions on the two hoisting tool split bodies.

And a fourth pin shaft is connected between the hinging positions of the clamping rods on the two lifting appliance split bodies.

The at least one hanger is provided with a locking device in a split manner.

Locking devices are arranged on the two hanger components, and a locking shaft is connected between the two locking devices.

The locking device includes: and the blocking shaft is hinged with the clamping hook on the hanger split body and matched with the clamping hook.

The utility model adopts the two connected slings to separate, has simple structure, can stably finish the lifting operation, avoids the occurrence of the phenomenon that the slings cannot be lifted due to small clamping force, and ensures the smooth running of the transportation operation. Secondly, the locking device is adopted to enable the lifting appliance to keep an opening state, so that the lifting appliance is prevented from being closed under the condition of empty lifting, and a certain opening cannot be formed to meet the lifting of the semicircular plate.

Drawings

Fig. 1 is a front view of an embodiment of the present utility model, fig. 2 is a left side view of fig. 1, fig. 3 is a top view of fig. 1, and fig. 4 is a use state of an embodiment of the present utility model.

Detailed Description

The present utility model as shown in fig. 1, 2 and 3 includes: two hoist components of a whole that can function independently, hoist components of a whole that can function independently includes: the two articulated connecting rods 2 are respectively articulated with the clamping rods 1, the bottom ends of the clamping rods 1 are hook claws, and the two clamping rods 1 are also articulated together. The two lifting appliances are connected together in a front-back symmetrical way through a connecting device, and the connecting device is a pin shaft. The concrete structure is as follows: the first pin shaft 8 is connected between the corresponding hinging positions of the connecting rods 2 on the two hanger components, the first pin shaft 8 penetrates through the hinging holes of the hinging positions of the connecting rods 2 and then is connected with the nuts 3, so that the hinging is formed, and the two hanger components are connected together. The second pin shaft 9 and the third pin shaft 10 are respectively connected between the hinged positions of the two connecting rods 2 and the clamping rods 1 on the two hanger components, the fourth pin shaft 7 is connected between the hinged positions of the clamping rods 1 on the two hanger components, and the connection modes of the second pin shaft, the third pin shaft and the fourth pin shaft are the same as those of the first pin shaft. The first pin shaft 8 is provided with a hoisting ring 4.

Locking devices are arranged on the two hanger components, and a locking shaft 5 is connected between the two locking devices. The locking device includes: a hook 11 and a blocking shaft 6 matched with the hook 11. The clamping hooks 11 of the two locking devices are respectively hinged at two ends of the first pin shaft, and the blocking shafts 6 are respectively connected to the outer sides of hinge points at two ends of the fourth pin shaft 7.

When the utility model is used, as shown in fig. 4, the hanging chain is penetrated into the hanging ring, the hanging chain is hung on the crane hook, and the clamping hook of the locking device is manually hung on the blocking shaft, so that the hanging tool is kept in an open state. And moving the crown block to the position right below the middle position of the semicircular plate to be transferred, lowering the lifting appliance to enable the bottom of the opening of the lifting appliance to fall onto the semicircular plate, manually pulling the locking device to enable the clamping hook of the locking mechanism to be separated from the blocking shaft, then lifting, and automatically clamping and lifting the semicircular plate 12 to the position above the preset position by the lifting appliance. After reaching the upper part of the preset position, the semicircular plate falls to the preset position, and at the moment, the lifting appliance can be automatically opened by jacking the semicircular plate, and the semicircular plate is placed at the preset position to finish the lifting operation.

The above examples merely represent a few embodiments of the present utility model and are not to be construed as limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit of the utility model, which are within the scope of the utility model.
