It is to be understood that the description of the embodiments herein is for purposes of illustration and explanation only and is not intended to limit the invention.

As shown in fig. 1 to 6, the jacking adjustment device of the present invention includes a support 1, a jacking screw 2, a jacking nut 3, a key 4, a bearing 5, and an adjustment rod 6; the support 1 is provided with a through hole, and part of the jacking screw rod 2 penetrates through the through hole and extends into the support 1; the jacking nut 3 is arranged on the support 1 through a bearing 5, and the jacking nut 3 is in threaded fit with the jacking screw rod 2; the jacking screw rod 2 is provided with a long key groove along the axial direction, and the key 4 is fixedly arranged in the support 1 and partially extends into the long key groove so as to limit the jacking screw rod 2 to rotate relative to the support 1; the adjusting rod 6 is arranged on the jacking nut 3 to drive the jacking nut 3 to rotate relative to the support 1 under the driving of external force.

In the utility model, because a part of the key 4 fixedly installed in the support 1 extends into the long key groove of the jacking screw 2, thereby the rotation of the jacking screw 2 relative to the support 1 can be limited, so that the jacking screw 2 can only move along the axial direction, and the jacking nut 3 is installed on the support 1 through the bearing 5, the jacking nut 3 can rotate relative to the support 1, and the jacking nut 3 is in threaded fit with the jacking screw 2, therefore, an operator only needs to operate the adjusting rod 6 to rotate the jacking nut 3, the jacking screw 2 can move along the axial direction, thereby realizing the jacking function, because the jacking screw 2 can not rotate relative to the support 1, and the jacked heavy object can not rotate relative to the support 1, therefore, the jacking screw 2 can not generate the rotational friction with the jacked heavy object in the jacking process, thereby the top of the jacking screw 2 is prevented from being worn, the weight can be stably supported in the jacking process, so that the problem of inclination is avoided.

In order to enable the jacking nut 3 to be stably supported on the support 1 without being offset or inclined during the rotation of the jacking nut 3, optionally, as shown in fig. 5, the jacking adjusting device includes a stopper 7, and the stopper 7 is mounted on the jacking nut 3 along the circumferential direction of the jacking nut 3 and partially extends to the side of the support 1 to limit the jacking nut 3 from moving in the radial direction.

The utility model discloses an among some embodiments, jacking nut 3 can be connected through T type screw-thread fit with jacking screw rod 2.

In order to make the jacking nut 3 obtain more stable support, optionally, as shown in fig. 6, the jacking adjusting device comprises a connecting block 8, a mounting hole is formed in the connecting block 8, a groove is formed in the upper portion of the support 1, a through hole is formed in the center of the groove, the connecting block 8 is arranged on the support 1 and enables the mounting hole and the groove to be coaxially arranged, and the jacking nut 3 is connected with the connecting block 8 through a bearing 5.

Since the jacking screw 2 applies a large axial load to the jacking nut 3 during jacking, in order to enable the jacking nut 3 to smoothly rotate when bearing the axial load, optionally, the jacking adjustment device comprises a first bearing 51 and a second bearing 52, the first bearing 51 is mounted on the upper part of the connecting block 8 to provide connection between the connecting block 8 and the upper part of the jacking nut 3, and the second bearing 52 is mounted on the lower part of the connecting block 8 to provide connection between the connecting block 8 and the lower part of the jacking nut 3. That is, the axial load is effectively transferred to the connection block 8 by the first bearing 51 and the second bearing 52, thereby relieving the burden of the jacking nut 3 so that the jacking nut 3 can smoothly rotate.

At present, in many work of lifting up the weight, such as boom marking work, position correction needs to be performed by moving the weight in the horizontal direction after the weight is lifted up, and in the prior art, the weight is moved in the horizontal direction only by manually knocking the support 1, which easily causes instability of the support 1, so that the weight is inclined or even falls off, and the operation is inconvenient. In order to solve this problem, as an alternative, the jacking-adjusting device includes a moving mechanism having a moving member that can move in a horizontal direction, and the pedestal 1 is provided on the moving member.

It should be understood that the moving mechanism can move the moving member in the horizontal direction in various ways, and in order to make the moving action more accurate and labor-saving, optionally, as shown in fig. 1 to 3, the moving mechanism includes a mounting seat 9, a moving screw 10 and a moving member as a moving nut 11; the mounting seat 9 is fixedly arranged, the movable screw 10 is erected on the mounting seat 9 and can rotate around the axis of the movable screw, and the movable nut 11 is in threaded connection with the movable screw 10. Because the mounting seat 9 can be fixedly mounted on the ground, the movable screw 10 is erected on the mounting seat 9 and can not move horizontally but only rotate around the axis of the movable screw 10, and when the movable screw 10 rotates, the movable nut 11 can move along the length direction of the movable screw 10 under the action of thread fit, so that the support 1 is driven to move horizontally.

It should be understood that the moving screw 10 may be rotated in a variety of ways, for example, a motor may be used to drive the moving screw 10. In some embodiments of the present invention, considering the reason of low cost, optionally, the moving mechanism includes a hand wheel 12, the hand wheel 12 is coaxially connected with the moving screw 10, and the hand wheel 12 can drive the moving screw 10 to rotate around its axis under the driving of the external force. Therefore, in the above embodiment, the moving screw 10 can be operated to rotate by manually rotating the hand wheel 12, which saves the cost.

In order to enable the support 1 to move horizontally more stably, optionally, the moving mechanism includes a nut sleeve 13 and a moving base 14, the nut sleeve 13 is fixedly sleeved on the moving nut 11, the moving base 14 is horizontally arranged and fixedly connected with the nut sleeve 13, and the support 1 is mounted on the moving base 14. Due to the fixed connection among the moving nut 11, the nut sleeve 13 and the moving base 14, the moving base 14 is ensured to have good stability during horizontal movement, so that the support 1 arranged on the moving base 14 can move horizontally more stably.

In order to enable the support 1 to stably move along the length direction of the moving screw 10 without deviation when adjusting the horizontal position of the lifted heavy object, optionally, the lifting adjusting device includes a guide assembly, the guide assembly includes a guide rail 15 extending along the length direction of the moving screw 10 and a slide block 16 slidably disposed on the guide rail 15, and the slide block 16 is fixedly connected with the moving base 14.
