Technical Field
The utility model belongs to hoist and mount class device, in particular to be used for relieving relaxation and put and roll-up cable and hoist and mount cable drum's device.
Background
In the oil and gas exploitation drilling industry, a cable can be integrally lowered to an oil well along with an oil pipe in the process of descending the well, and in order to prevent the cable from being damaged, the cable is safely and smoothly lowered to the oil well, a special cable reel lifting device is generally required to lift a cable reel to the air and rotate, so that an operator is protected, and the cable can be safely and conveniently laid. The traditional cable drum lifting device generally adopts a cable drum rack as a fixing device of a cable drum, and the fixing mode has the problems of high cost, complex operation, safe operation risk and large cable stress.
Disclosure of Invention
The utility model aims at providing a cable drum hoisting device for improving shortcoming and the weak point that exists among the above-mentioned traditional cable drum fixing device, reasonable in design not only, simple structure, firm, reuse rate is high moreover, the installation is convenient and performance is outstanding.
The utility model aims at adopting the following technical scheme to realize: a cable drum hoisting device which characterized in that: the lifting arm is movably connected to the lower end of the barrel through a second cylindrical pin and used for bearing a cable reel, the position state of the lifting arm is controlled by interconnecting elastic traction ropes between the lifting arm and the movable shaft, one end of each elastic traction rope penetrates through the barrel through the second cylindrical pin and is connected with the lifting arm, the other end of each elastic traction rope is connected with the movable shaft and the rotary lifting ring through the first cylindrical pin, a turnover side ring is arranged on one side of the upper end of the barrel, the first limiting pin is inserted into an end hole of the first cylindrical pin, the first cylindrical pin is prevented from moving out, the second limiting pin is inserted into an end hole of the second cylindrical pin, and the second cylindrical pin is prevented from falling off from the structural position.
Compared with the prior art, the utility model has the characteristics of reasonable in design not only, simple structure is firm, has reuse rate height, installation convenient and performance outstanding moreover.

Detailed Description
As shown in fig. 1, fig. 2 and fig. 3, the utility model relates to a cable drum lifting device, its characterized in that: the lifting arm comprises a movable shaft 4 and a barrel 6, the lower end of the movable shaft 4 is fixed at the upper end of the barrel 6 through a first cylindrical pin 2, a rotary lifting ring 3 capable of rotating is mounted at the upper end of the movable shaft 4, the lifting arm 1 is movably connected to the lower end of the barrel 6 through a second cylindrical pin 9 and used for bearing a cable reel 11, the position state of the lifting arm 1 is controlled by the interconnection of an elastic traction rope 8 between the lifting arm 1 and the movable shaft 4, one end of the elastic traction rope 8 penetrates through the barrel 6 through the second cylindrical pin 9 to be connected with the lifting arm 1, the barrel 6 is connected with the movable shaft 4 through the first cylindrical pin 2 at the other end, the rotary lifting ring 3 is connected with the barrel 6, a turnover side ring 5 is arranged on one side of the upper end of the barrel 6, the first limiting pin 7 is inserted into an end hole of the first cylindrical pin 2 to prevent the first cylindrical pin 2 from moving out, and the second limiting pin 10 is inserted.
As shown in fig. 4, when the lifting device is used, the lifting device is placed in a central hole of the cable drum 11, then the rotary lifting ring 3 is lifted, the rotary lifting ring 3 drives the movable shaft 4 to move upwards, and meanwhile, the movable shaft 4 pulls the elastic traction rope 8 to generate axial tension, so that the lifting arm 1 rotates 90 degrees around the second cylindrical pin 9, as shown in fig. 5, the cable drum 11 can be lifted into the air by continuously lifting the rotary lifting ring 3; at this time, due to the rotation function of the rotary hoisting ring 3, the cable reel 11 can rotate around the center thereof in the air, thereby realizing the lowering or winding of the cable.
As shown in fig. 6, the function of the turning side ring 5 is to turn the cable drum in a rolling state to a flat placement state.
The first limit pin 7 is inserted into the end hole of the first cylindrical pin 2, and the second limit pin 10 is inserted into the end hole of the second cylindrical pin 9, so that the cylindrical pins are prevented from falling off from the structural position.
When the hoisting is finished, the lifting arm 1 of the lifting device naturally droops under the action of gravity and returns to the state shown in fig. 2, so that the lifting device can be taken out very conveniently.
The load of the lifting device depends on the inner and outer diameters of the used tubular members, and the larger the outer diameter/wall thickness of the tubular members is, the larger the load can be lifted, and conversely, the smaller the load can be lifted.
As can be seen from the operation process, the device has the characteristics of simple structure, convenient and easy operation, low maintenance cost and easy popularization and use.
The above description is only an embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are intended to be covered by the scope of the present invention.
