The utility model has the function of horizontal adjustment, can realize pre-leveling, and has reliable connection and stronger practicability.
Description
Technical Field
The utility model relates to the field of engineering machinery, in particular to an adjustable hinging seat capable of realizing a pre-leveling function.
Background
In engineering machine tool field, the articulated seat of cross is used for installing and connects the mast on the chassis on the pylon, realizes laying down and the erection of mast, and current articulated seat of cross exists the problem: the joint of the cross hinging seat and the upper chassis is provided with a gap, so that the cross hinging seat can swing left and right in a certain range, when the tower is started, the mast is started up due to uneven stress on the left side and the right side, and the damage of the cross hinging seat can be caused, so that the tower is started up.
Disclosure of Invention
The utility model aims to overcome the defects of the prior art, provides an adjustable hinging seat for a mast of a drilling machine, effectively solves the problem of uneven stress on two sides of a cross hinging seat, and has a horizontal adjusting function.
In order to solve the technical problems, the utility model is realized as follows:
an adjustable hinge mount for a rig mast, comprising a cross hinge mount mounted on a pylon upper chassis for connection to the mast, characterized in that: the lower part of the cross hinging seat is provided with a shaft hole and is coaxially connected with the shaft hole in the middle of the upper chassis of the tower crane through the shaft hole; the upper portion bilateral symmetry of cross articulated seat sets up adjustment mechanism, adjustment mechanism is used for adjusting the swing range of cross articulated seat both sides, is used for locking cross articulated seat, eliminates both sides clearance, ensures that the mast erects perpendicularly.
The adjusting mechanism comprises an adjusting bolt vertical to the ground and a nut component for limiting the extending length of the adjusting bolt, and the left-right swing amplitude of the whole cross hinge seat is controlled by controlling the angle of the adjusting bolt from the platform through the nut.
Considering that when the cross hinge seat is arranged in the middle of the upper chassis of the tower, the cross hinge seat can incline or swing left and right in a certain range, the structure of the adjusting mechanism is arranged for being firstly adjusted to be in a pre-horizontal state so as to limit the left and right swinging of the cross hinge seat, and the adjusting mechanism controls the extension length of the adjusting bolt through the tightening of one adjusting bolt and two nuts arranged at the upper and lower positions of the adjusting bolt;
when the mast is on the tower, the adjusting bolt stretches out until the bottom of the adjusting bolt abuts against the platform, so that the cross hinging seat is limited to swing left and right; when the tower is lifted, the bottom of the adjusting bolt is in clearance with the platform and is not contacted with the platform when the mast is vertically and vertically horizontally adjusted, the adjusting bolt is used for being matched with the lifting oil cylinder to realize the adjustment of the verticality of the mast, and the locking device is released after the tower is lifted, so that the aim of adjustment is fulfilled.
In order to strengthen the strength of the adjusting mechanism, the adjusting mechanism is improved as follows: the adjusting mechanism comprises a horizontal plate and two side reinforcing ribs, and is connected in a welding mode, and the adjusting bolt and the nut component are arranged on the horizontal plate between the two side reinforcing ribs; the shaft hole at the lower part of the cross hinging seat is sleeved with a bearing and two side reinforcing plates.
In conclusion, the utility model overcomes the defects of the traditional cross hinge seat, has the horizontal adjusting function, can realize pre-leveling, and has reliable connection and stronger practicability.
Drawings
The utility model is described in further detail below with reference to the attached drawings and embodiments:
fig. 1 is a schematic structural view of the present utility model.
Detailed Description
As shown in fig. 1: the adjustable hinging seat comprises a cross hinging seat, wherein the cross hinging seat is arranged on an upper chassis of a pylon and used for being connected with the mast, and the lower part of the cross hinging seat is provided with a shaft hole 1 and is coaxially connected with the shaft hole in the middle of the upper chassis of the pylon through the shaft hole; the two sides of the upper part of the cross hinge seat are symmetrically provided with adjusting mechanisms 2, and the adjusting mechanisms are used for adjusting the swing amplitude of the two sides of the cross hinge seat, locking the cross hinge seat, eliminating the gaps of the two sides and ensuring the vertical erection of the mast; the adjusting mechanism comprises an adjusting bolt vertical to the ground and a nut component for limiting the extending length of the adjusting bolt, and the left-right swing amplitude of the whole cross hinge seat is controlled by controlling the angle of the adjusting bolt from the platform through the nut.
In the above structure, in order to enhance the connection strength, the adjusting mechanism comprises a horizontal plate 21 and two side reinforcing ribs 22, and is connected by welding, and the adjusting bolt 23 and the nut assembly are arranged on the horizontal plate between the two side reinforcing ribs; the shaft hole at the lower part of the cross hinging seat is sleeved with a bearing and two side reinforcing plates 3.
When in actual use, the method comprises the following steps: when the mast is on the tower, the adjusting bolt stretches out until the bottom of the adjusting bolt abuts against the platform, so that the cross hinging seat is limited to swing left and right; when the tower is lifted, the mast is vertically and vertically horizontally adjusted, and a gap is reserved between the bottom of the adjusting bolt and the platform and is used for being matched with the lifting oil cylinder to realize the adjustment of the verticality of the mast.
