The lifting tripod consists of a tripod, a winch, a foot chain and the like. The telescopic support leg is generally made of high-strength light alloy, the weight is reduced to the greatest extent while the strength is ensured, the safety coefficient is large, the telescopic support leg is provided with hanging holes for assembling a plurality of sets of safety ropes, and the support leg is provided with a ring-shaped protection chain.
In the prior art, in municipal pipeline construction, a lifting tripod is erected at an opening and a grooving part with a wellhead or a connecting underground space to lift equipment, and due to underground operation, part of equipment is heavy, if the equipment needs to be replaced, the original equipment needs to be lifted out of the ground and transferred, and then the replaced equipment is placed in a corresponding position to be installed and connected. In the temporary construction, if the single-arm hoisting equipment is adopted, the occupied area is large, and the single-arm hoisting equipment is supported and fixed in side direction, so that the single-arm hoisting equipment has a large volume in order to realize a certain lifting requirement.

When the lifting tripod is supported at the wellhead, the lower ends of the supporting legs are fixed on the ground through bolts or direct rivets, and meanwhile, the hand hoist is mounted at the top of the support, and a user pulls the hand hoist aside to enable the hooks to move up and down. When lifting, the heavier equipment is lifted out of the ground by the hand hoist, and the equipment needs to be placed on external bearing equipment, typically a trolley. The existing operation mode is that after the equipment is lifted to the ground, the equipment is kept in the lowest height state, then the equipment is pulled to one side of a lifting tripod by a plurality of workers, so that the equipment is close to a bearing structure, and when the equipment is limited above the bearing structure, one person slowly operates a manual hoist to release the equipment, so that the equipment finally falls on the bearing structure. Because this kind of mode needs to pull equipment through many people, if the pulling distance is great, the component of the weight of whole equipment in the horizontal direction is great, makes the pulling force that its needs location be big more, then not only need many people to operate, often simultaneously because the particularity of well head position leads to bearing structure unable to be close to well head department, then still can place equipment on the subaerial next to the well head earlier, then shifts through other equipment. Meanwhile, accidents frequently occur in actual construction, for example, the manual hoist is disconnected from the lifting tripod due to the fact that the equipment stretches to one side more, or the equipment is disconnected from the manual hoist, so that the equipment is possibly damaged, and meanwhile, personnel accidents can be caused due to the fact that the equipment is pressed to an operator.

The specific mode of this mode is not shown in the drawings, and it should be noted that the revolving rack 1 is connected with the movable end through a bolt/screw hole, but is not limited to the specific arrangement position of the bolt/screw hole, but because the revolving rack 1 is rotationally connected with the fixed seat 4, in order not to affect the connection relationship, the bolt is arranged on the movable end for convenient operation. A bolt is provided on the turret 1, the bolt having an operable end portion at the lower portion of the movable end, and the bolt is rotated to reciprocate in the vertical direction. The rotating frame 1 is provided with corresponding screw holes, when the movable end is positioned at the lower part of the rotating frame 1 and the screw holes are aligned with the axes of the bolts, the bolts are rotated to enable the movable end to be matched with the screw holes, so that the movable end is fixedly connected with the rotating frame 1, stability can be improved when a heavy object is lifted, and the movable end can rotate along with the rotating frame 1.
Further, as shown in fig. 1-7, the first implementation of the stretching arm in this embodiment is shown in a different state, in which the stretching arm is a folding structure that can rotate and unfold in a horizontal plane.
The stretching arm comprises a first connecting end fixedly connected with the rotating frame 1, a support arm 5 and a fixing part 6, wherein the support arm 5 is provided with at least two sections of sub-parts rotating in the horizontal direction; one end part of the support arm 5 is movably connected with the first connecting end, the other end part of the support arm is connected with the fixed part 6, and the fixed part 6 positioned below the rotating frame 1 is detachably connected with the rotating frame 1 through the limiting structure; when lifting, the support arm 5 is in a folding state, the movable end is disconnected with the support by operating the limiting mechanism in the folding state, and the sub-part connected with the first connecting end is moved on the support arm 5, so that the support arm 5 moves outside the supporting space, and the fixing part 6 drives the lifter 3 with equipment to move to an external bearing structure to stop releasing.
The first connecting end is rotationally connected with the support arm 5, the rotation shaft is in the horizontal direction, the fixed seat 4 is rotationally connected with the support arm 5, and the rotation shaft is collinear with the rotation shaft of the first connecting end; the movable limiting parts limiting the degrees of freedom of the two ends of the support arm 5 are arranged at the rotating joints of the two ends of the support arm 5, when the support arm 5 is in a folded state, the movable limiting parts are moved to restore the degrees of freedom of the two ends of the support arm 5, the support arm 5 is rotated to rotate around the first connecting end and the fixed part 6 limited by the limiting mechanism and is stored in the supporting space, and then the rotating frame 1 is rotated to adjust the extending direction of the extending arm.
Before the support arm 5 is unfolded, the movable limiting piece is moved to limit the freedom degrees of the two ends of the support arm 5, and then the fixing part 6 is separated from the rotating frame 1 through the limiting mechanism to unfold the support arm 5 in the horizontal direction.
As can be seen in fig. 7, after the arm 5 is fully unfolded, it can be extended outwards from the supporting space for a certain distance, and since the arm 5 is displaced in the horizontal direction, the weight of the weight pulled by the lifter 3 is always borne by the bracket, the resistance of slowly moving the arm 5 is smaller than the resistance of the tripod diagonal weight in the prior art, so that one person can operate to pull out the tripod diagonal weight and stably place the weight on the prepared bearing structure.
The movable limiting part is not shown in the figure, and it is to be noted that the support arm 5 is a rod member structure extending linearly, the support arm 5 is a hinge structure, two end faces of the support arm are provided with sliding grooves, and the sliding grooves are internally provided with bolts serving as the movable limiting part. And corresponding bolt grooves are formed in the first connecting end and the fixing part 6, when the support arm 5 is required to be folded from a horizontal state, bolts which are originally inserted into the bolt grooves are pulled out, wherein the operation end of the bolts is arranged on the side face of the support arm 5. At this time, the bolt is disconnected with the bolt groove, and the support arm 5 can be rotated downwards by 90 degrees. And because the fixing part 6 and the rotating frame 1 are limited and fixed through bolts or other structures in the state, the supporting arm 5 is not stressed when the lifter 3 lifts the heavy object. The fixing part 6 in this state can rotate with the turret 1 to adjust the orientation of the arms 5, facilitating the pulling out of the extension arms towards the carrying structure. When the lifter 3 is connected with the weight and is suspended to a determined position above the ground, the lifter needs to be transferred to a bearing structure, at the moment, the support arm 5 is pulled and rotated to a horizontal state from a vertical state to one side, and then bolts at two sides are inserted into corresponding bolt grooves to realize limit connection. Then the bolt is loosened to disconnect the fixing part 6 from the swivel base, and the support arm 5 is fully stressed at the moment. The user pulls the handle arranged on the support arm 5 at one side from one side to horizontally pull the handle out to one side, and at the moment, the support arm 5 horizontally rotates around the hinge position of the support arm so that the fixing part 6 drives the weight to move to the bearing structure, the support effect is kept by the support arm 5, and the user can independently operate the lifter 3 to stably place the weight on the bearing structure to finish the transferring work.
The second implementation manner, not shown in the figure, is that the first connection end is rotationally connected with the support arm 5, the rotation axis is in a vertical direction, the whole support arm 5 and the first connection end are rotated to enable the support arm 5 to be received in the supporting space, and then the rotating frame 1 is rotated to adjust the extending direction of the extension arm.
Unlike the above-described embodiments, this storage manner rotates the arm 5 in the horizontal direction, and the rotation direction of the first connection end and the arm 5 is not the same as the gravity direction of the apparatus, so that even if the fixing portion 6 is not fixedly connected with the turret 1 by the limiting mechanism, the whole arm 5 can provide a better suspension supporting force for the apparatus, and at the same time, it has a smaller space occupation in the vertical space by this storage manner.
8-12, a different rotation limiting mode of the support arm 5 is shown, the movable limiting piece is a telescopic rotating shaft 7 arranged at the end part of the support arm 5 and sliding along the length direction of the support arm 5, the telescopic rotating shaft 7 is rotationally connected with the first connecting end and the fixing part 6, the end part of the support arm 5 is provided with an inward concave sink, and the telescopic rotating shaft 7 slides in the sink; when the telescopic rotating shaft 7 is positioned in the sinking groove, the inner wall of the sinking groove limits the rotation freedom degree of the telescopic rotating shaft 7, and when the telescopic rotating shaft 7 is positioned outside the sinking groove, the rotation freedom degree is provided.
In a fourth implementation, not shown in the figures, the stretching arm comprises a support arranged on the rotating frame 1 and an L-shaped support arm 5, wherein any point on the support arm 5 is hinged with the support; the support arm 5 is divided into a connecting section and an operating section by a hinge point, the end part of the connecting section is movably connected with the lifter 3, and when the lifter 3 is connected with equipment for lifting, the connecting section rotates to a vertical state around the support; the tip of operating section is the operating portion that stretches out to the support outside, and operating portion is greater than the distance of expansion end and support with the distance of support, and when lifting by the 3 jointing equipment of lifting mechanism promoted, the operating section supports with revolving rack 1.
Wherein, the operation end itself includes two kinds of setting methods, has a nested both ends structure promptly, and wherein shorter sleeve can be connected with the linkage segment is integrative, carries out spacingly to the rotation of linkage segment when promoting, or does not support spacingly with revolving rack 1 through the automatic vertical decurrent setting method of linkage segment. When the lifted equipment needs to be moved, the sleeve rod can be inserted into the sleeve from the outside, and then the operating end is manually pressed downwards by a person, so that the fixed part 6 at the end part of the movable end is lifted, and the equipment is moved towards the ground at the side of the wellhead by utilizing the lever principle. Because detachable structural design is adopted, better labor-saving effect can be realized by replacing the loop bar structure of the longer operation section.
