Detailed Description
The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.
As shown in fig. 1 to 3, the utility model comprises a sleeve 1 which is transversely placed, a left extension rod and a right extension rod 2 are arranged inside the sleeve 1, and the extension rods 2 can move left and right inside the sleeve 1; the outer edge surface of the sleeve 1 is provided with a left group of support modules and a right group of support modules, each group of support modules consists of a plurality of telescopic rods 3, the telescopic rods 3 are positioned in the same vertical plane, the inner ends of the telescopic rods 3 are fixed on the sleeve 1, the outer ends face different directions, and the length of the telescopic rods 3 can be adjusted; a vertical rod 4 is fixed at the end part of each extension rod 2, and a hanging ring 6 is arranged on each vertical rod 4.
In order to realize the movement of the extension rod 2 in the sleeve 1, a cylindrical protruding block is fixed at one end of each extension rod 2 in the sleeve 1, and the inner diameters of the left end and the right end of the sleeve 1 are smaller than the diameter of the protruding block.
In order to realize the length adjustment of the telescopic rod 3, the telescopic rod 3 consists of a shell 301 and a top rod 302 in the shell 301, a plurality of through holes 303 are uniformly distributed on the shell 301 from top to bottom, and a positioning hole is formed on the top rod 302; a pin 304 penetrating through the through hole 303 and the positioning hole is inserted into the housing 301.
In order to avoid sliding, the outer end of each telescopic rod 3 is fixed with a rubber layer 8.
In order to enable the vertical rods 4 to play a certain role in blocking the inclination of the pipeline, a cylinder 5 capable of moving up and down along the vertical rods 4 is sleeved outside each vertical rod 4, a limiting block arranged inside the cylinder 5 is arranged at the upper end of each vertical rod 4, and a tension spring 7 is connected between the upper end of each vertical rod 4 and the cylinder 5; the hanging ring 6 is fixed on the upper end surface of the cylinder 5.
In order to save the installation time and balance the stress, the number of the telescopic rods 3 of each group of the support modules is three, and the included angle between the adjacent three telescopic rods 3 is 60 degrees.
The utility model discloses during the use, at first on two rings 6 of controlling respectively fixed a wire rope, later according to the size of the diameter of the cement pipeline of required hoist and mount, adjust the length of telescopic link 3, when adjusting the length of a plurality of telescopic links 3, need adjust the length of a plurality of telescopic links 3 to the same length, when adjusting the length of telescopic link 3, can differentiate according to the position of through-hole 303 on the shell 301 of telescopic link 3.
The length adjustment of telescopic link 3 does not have special requirement, but need consider on the one hand can not the overlength after adjusting, can be smooth insert the whole device into the cement pipeline in, on the other hand can not the overlength, should make three telescopic link 3 support the position of pipeline inner wall a little as far as possible, avoids stress concentration to the central point on upper portion.
After the length of the telescopic rod 3 is adjusted, the whole device can be inserted into a cement pipeline, and at the moment, the length of the extension rod 2 is properly stretched or contracted according to the length of the cement pipeline, so that the left vertical rod 4 and the right vertical rod 4 are just arranged on the left side and the right side of the cement pipeline; then fixing the upper ends of the two ropes on a hook of the crane; the edge can be lifted.
When in hoisting, the vertical rod 4 is vertically upward, and the support module is also upward; the rubber layer 8 at the end part of each telescopic rod 3 is in contact with the inner side wall of the cement pipeline, the cylinder 5 sleeved outside the vertical rod 4 is stretched and the tension spring 7 inside is stretched in the hoisting process; by stretching the cylinder body 5, on one hand, the lengthened vertical rod 4 and the cylinder body 5 can play a role in blocking the left side and the right side of the cement pipeline, and the cement pipeline is prevented from being separated from the whole lifting appliance after being inclined; on the other hand, the tension spring 7 in the cement pipeline can play a role in buffering stress, and the overlarge impact force caused by the stress of the cement pipeline during lifting and putting down is avoided.
After the hoisting is finished, the cement pipeline is put down, and then the steel wire rope is untied, so that the whole clamp can be taken out for next hoisting.
When the device is not used, the telescopic rod 3 can be contracted, and the extension rod 2 is inserted into the large sleeve 1, so that the whole device is small in size, small in occupied area and convenient to store.
This device is through setting up a plurality of telescopic links 3 towards different position, through adjusting a plurality of telescopic links 3 to the same length to can make the outer end of a plurality of telescopic links 3 can the inside wall of multiple spot support cement pipeline simultaneously, guaranteed the balance of cement pipeline inside wall atress.
Through the length of adjusting telescopic link 3 and the length of extension rod 2 in this device, can be adapted to the cement pipeline of different diameters with incessant length to realized only needing one set of hoist alright with carry out the purpose of hoist to the pipeline of difference.
Two montants 4 and the outer barrel 5 of montant 4 not only play the effect of hoist and mount about this device, can play the buffering atress in addition, block the effect of pipeline slope.
