Description

Technical Field

[0001] The utility model relates to the field of hydraulic supports, in particular to an integrated column adjustment device. Background Art

[0002] In existing integrated support and transport systems, the support columns are pinned to the connecting base, which is then pinned to the guide rails. The support columns are fixed in a relatively fixed position within the integrated support and transport system, and their position cannot be adjusted. During actual tunnel advance support, when the support columns connect to the roof, they can damage the anchor rods and cables of the tunnel roof, thereby compromising the integrity of the roof. This can easily cause the roof to shatter where the anchor rods and cables are damaged, and the resulting fall of the broken roof can easily lead to safety accidents.

[0003] The utility model patent with authorization announcement number CN221169625U discloses a lateral self-moving unit bracket, including a base, a column provided on the base, a top beam provided on the top of the column, a self-moving frame provided on the periphery of the base, an internal cavity of the self-moving frame forming a space for accommodating the base, a plurality of bottom lifting jacks provided on the self-moving frame, and the bottom lifting jacks used to lift the base off the bottom surface; a lateral oil cylinder and a pair of guide rods provided on the base, the two ends of the guide rods being connected to the self-moving frame, one end of the lateral oil cylinder being fixed to the base, and the other end of the lateral oil cylinder being connected to the self-moving frame. This lateral self-moving unit bracket does not require auxiliary handling equipment and can achieve self-lateral movement only by relying on the structure of the bracket itself. However, this lateral self-moving unit bracket has a complex structure and relies on guide rods for support, resulting in weak support stability and the defect of guide rods bending and getting stuck. Utility Model Content

[0004] In order to realize the lateral self-movement of the integrated machine adjustment column, increase the support area and stability, and avoid the phenomenon of getting stuck during the self-movement process, the technical solution adopted by the utility model is: an integrated machine adjustment column device, including a base, a sealing plate, a support seat, a telescopic column and a side push jack;

[0005] The base is provided with sealing plates on all sides, and the sealing plates and the base are combined to form a box-like structure with a semi-open top;

[0006] The support seat is slidably arranged on the base, the bottom of the telescopic column is hinged to the support seat, and the top of the telescopic column extends out of the box-type structure;

[0007] The fixed end of the side push jack is arranged on the outside of the sealing plate, and the movable end of the side push jack passes through the sealing plate and is connected to the support seat. The side push jack is used to drive the support seat to slide along the width direction of the base.

[0008] Based on the above, in order to ensure the smooth horizontal sliding of the telescopic column, a sliding groove is opened on the upper surface of the base, and the support seat is slidably arranged in the sliding groove.

[0009] Based on the above, in order to increase the stability of the structure, the width of the support base is greater than the diameter of the telescopic column, and the width of the support base is smaller than the width of the base.

[0010] Based on the above, in order not to destroy the structural integrity of the original telescopic column and to ensure the performance stability of the telescopic column, the side thrust jack includes a sleeve fixing seat, a piston sleeve, a piston rod, a first piston block, a second piston block and a protective sleeve;

[0011] The sleeve fixing seat is connected to the bottom of the piston sleeve, and a side thrust jack mounting seat is provided on the support seat. The sleeve fixing seat is detachably mounted on the side thrust jack mounting seat through a fixed rib plate, and a second piston block is provided at the outer end of the piston sleeve;

[0012] The protective sleeve cover is arranged on the outside of the piston sleeve and fixed to one of the sealing plates. The outer end of the piston rod is fixed to the inside of the protective sleeve by a fixing pin. The inner end of the piston rod is sleeved with a first piston block. The first piston block is in sliding engagement with the inner side wall of the piston sleeve, and the second piston block is in sliding engagement with the outer side wall of the piston rod.

[0013] The sealed cavity between the first piston block and the sleeve fixing seat forms a first hydraulic cavity, and the sealed cavity between the first piston block and the second piston block forms a second hydraulic cavity.

[0014] Based on the above, in order to avoid the jamming phenomenon during the lateral movement, the side thrust jack mounting seat is installed on the top of the support seat, and the piston sleeve is arranged vertically to the support seat.

[0015] Based on the above, the fixed end of the piston rod is connected to a valve that connects the first hydraulic chamber and the second hydraulic chamber.

[0016] The present invention has substantial features and advancements over the prior art. Specifically, the integrated adjustable column device provided by the present invention provides power for the horizontal movement of the telescopic column by designing the base of the adjustable column into a base form, hingedly connecting a support seat to the bottom of the telescopic column, and setting the support seat linearly slidingly inside, and providing a side push jack connected to the support seat on the base, thereby enabling the telescopic column to move horizontally within a certain range. This allows the column to avoid devices such as roof anchors and cables when connected to the roof, thereby avoiding the defect of damaging the anchors and cables of the tunnel roof and thus damaging the integrity of the roof. At the same time, since the support seat is in direct contact with the base, the entire support seat can be supported by the base, increasing the support area and stability, and avoiding the phenomenon of jamming.

[0017] Furthermore, by installing the side push jack mounting seat on the support seat and detachably pressing the side push jack on the side push jack mounting seat by using a fixed rib plate to press, it is possible to avoid improving the existing telescopic column structure, thereby ensuring the integrity of the existing telescopic column structure and the stability of its performance.

[0018] Furthermore, by fixing the protective sleeve on the sealing plate on one side, fixing the outer end of the piston rod inside the protective sleeve through a fixing pin, connecting the piston sleeve to the side push jack mounting seat, and sealing and slidingly fitting the piston rod and the piston sleeve through the first piston block and the second piston block, the safety of the side push jack during extension and retraction is effectively protected.
