Description

Support cover special lifting device

Technical Field

The utility model relates to a support cover special lifting device belongs to hoist technical field.

Background

When the support sleeves of the movable arm and the bucket rod of the excavator are assembled, the axis of the support sleeves is placed in a mode of being perpendicular to the ground. In the prior art, a lifting rope penetrates into an inner hole of the support sleeve, then the support sleeve is lifted to an installation position, and then the lifting rope is taken out. Because of this way of hoisting, the axis of the support sleeve is not perpendicular to the ground, so the position of the support sleeve needs to be adjusted. This is very unsafe and inefficient.

Preferably, the method comprises the following steps: the upper surface of position sleeve is greater than the lower surface, sets up the screw hole that runs through whole position sleeve on the upper surface to be equipped with one section screw thread district on the inner wall that the position sleeve is located locating piece one end, set up the first screw thread of usefulness of screwing up each other with the screw thread district on solid pipeline is located locating piece one end pipe wall, still be equipped with one deck silica gel gasket on the lower surface for the collision prevention.

Preferably, the method comprises the following steps: the bent part on the solid pipeline is provided with a second thread, so that the solid pipeline is prevented from being accidentally dropped to be damaged by a smashing method.

Preferably, the method comprises the following steps: the screw can be embedded in the positioning sleeve and integrated with the surface of the positioning sleeve or arranged above the positioning sleeve, and the handle is detachably arranged below the positioning sleeve or sleeved on the positioning sleeve and parallel to the positioning sleeve.

Preferably, the method comprises the following steps: the screw is an octagonal screw.

The utility model discloses a hoist lifts by crane supports the cover, can make and support set axis perpendicular to ground and put into mounted position, need not adjust supporting set position again. The utility model has the advantages of simple structure, convenient operation, fixed firm and safe high efficiency, long service life, etc.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings: as shown in fig. 1, a special lifting appliance for a supporting sleeve, which comprises a lifting hook 1 and a positioning sleeve 2, wherein the lifting hook 1 comprises a left solid pipeline 3 and a right solid pipeline 3 which are in an L shape, the positioning sleeve 2 is sleeved on the solid pipeline 3, a limiting convex block 4 is arranged above the positioning sleeve 2, a connecting threaded column 5 with a diameter smaller than that of the solid pipeline 3 is arranged at the top of the solid pipeline 3 above the limiting convex block 4, a positioning block 6 is arranged on one side away from the connecting threaded column 5, a fixing hole 8 with a thread 15 is arranged on the positioning block 6, a threaded hole 9 is arranged on the positioning sleeve 2, a screw 10 is arranged in the threaded hole 9, a handle 11 is sleeved on the screw 10, the handle 11 is rotated, the screw 10 penetrates through the threaded hole 9 and the fixing hole 8 on the positioning block 6 and then is screwed up and fixed, and the limiting convex block is arranged above the positioning sleeve, so that the positioning sleeve can be well prevented from slipping out from the top of the lifting hook in the carrying process.

The upper surface of the locating sleeve 2 is larger than the lower surface, a threaded hole 9 penetrating through the whole locating sleeve is formed in the upper surface, a section of threaded area 12 is formed in the inner wall, located at one end of the locating block 6, of the locating sleeve 2, a first thread 7 used for being screwed with the threaded area 12 is formed in the wall, located at one end of the locating block 6, of the solid pipeline 3, a layer of silica gel gasket 13 is further arranged on the lower surface and used for preventing collision, a second thread 14 is arranged at a bent position of the solid pipeline 3 and used for preventing the solid pipeline 3 from being broken due to accidental falling, the screw 10 can be embedded into the locating sleeve 2 and integrated with the surface of the locating sleeve 2 or arranged above the locating sleeve 2, the handle 11 of the bolt can be detachably mounted below the locating sleeve 2 or sleeved on the locating sleeve 2 and parallel to the locating sleeve 2, the screw 10 is an octagonal screw, the silica gel gasket can prevent a lifting appliance from falling to damage to the bent position of the solid pipeline due to the fact that the locating sleeve slides up and down on the solid pipeline in the transporting or carrying process, and can reduce friction and collision between the locating sleeve and the locating block.

The utility model discloses an operation mode as follows:

when using, put into supporting cover hole with lifting hook protrusion one end, and make the hook end be in and support terminal surface under the cover, with the position sleeve along solid pipeline downstream, the screw that sets up through the pipe wall outside earlier carries out the rotation and fixes and touch the locating piece, then the handle on the rotation position sleeve carries out dual fixed in the fixed slot that the screw changes over to solid pipeline bottom locating piece into with the screw, make whole lifting hook more firm stable, through upwards pulling up the lifting hook, can will support set vertically to hang up, work efficiency is greatly improved.

The above description is only for the preferred 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 should be covered by the present invention.
