[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] like Figure 1 and Figure 2As shown, the present invention provides a combined bracket type multi-axis adjustable distance hydraulic lifting device, including a transverse bracket 10, on which a longitudinal bracket 20 is vertically arranged through a movable platform 11, the movable platform 11 translates along the length direction of the transverse bracket 10 to form a transverse movable structure, and a base 21 is arranged on the longitudinal bracket 20, and the base 21 translates along the length direction of the longitudinal bracket 20 to form a longitudinal movable structure.

[0040] The horizontal bracket 10 and the vertical bracket 20 form an xy axis, and the rotating column 30 forms a z axis, forming a three-dimensional positioning adjustment structure, which can further adjust the lifting position and expand the horizontal and vertical adjustments within a certain range.

[0041] A rotating column 30 is arranged on the base 21, a hanging arm 31 is arranged on the top of the rotating column 30, a hanging chain 40 is arranged on the hanging arm 31, and a stabilizing arm 32 is arranged on the column. One end of the stabilizing arm 32 abuts against an object at one end of the hanging chain 40 to form a stabilizing structure. The stabilizing arm 32 rotates around the connection between it and the rotating column 30, and one end of the stabilizing arm 32 moves along the lifting direction of the hanging chain 40 to form a tracking stabilizing structure.

[0042] The Y-structure double-end lifting chain 40 can be lifted at a single point or two points, thereby reducing the shaking of the object when it is lifted and improving the stability of the object when it is lifted.

[0043] The stabilizing arm 32 is composed of a hydraulic telescopic rod with a telescopic structure to ensure that during the rotation process, the end is always located at one side of the hanging object for stability. The stabilizing arm 32 moves together with the movement of the lifting chain 40 to achieve the purpose of synchronous movement.

[0044] The present invention forms a three-dimensional adjustable distance hydraulic lifting structure with xyz axes through bidirectional brackets and columns, and forms a movable supporting structure through the combined translation of multiple groups of hydraulic support groups, thereby expanding the operation range of the hydraulic crane, enabling movement in a small space, reducing the equipment and time for moving the rack, and being more adaptable to different ground environments, achieving the purpose of adjusting the balance, and stabilizing the objects while lifting them, further reducing the shaking of the device and improving the stability.

[0045] By the translation of the mobile platform 11 on the horizontal bracket 10, the rotating column 30 is driven to move in the x-axis direction, and then by the translation of the base 21 on the vertical bracket 20, the rotating column 30 is driven to move along the y-axis direction, and the built-in hydraulic mechanism of the rotating column 30 drives the boom 31 to move along the z-axis direction, thereby achieving three-dimensional distance adjustment of the boom 31 in the xyz axis.

[0046] Hydraulic drive mechanisms are provided on both the transverse support 10 and the longitudinal support 20 , and the movement of the movable platform 11 and the base 21 on the transverse support 10 and the longitudinal support 20 are controlled by the hydraulic drive mechanisms.

[0047] The object is hoisted by the lifting chain 40, and the stabilizing arm 32 moves along with the movement of the lifting chain 40. The stabilizing arm 32 stabilizes the hoisted object to reduce the shaking of the object during the hoisting process, thereby affecting the stability of the hydraulic lifting device.

[0048] like Figure 1 , Figure 2 and Figure 4 As shown, the transverse bracket 10 and the longitudinal bracket 20 form an xy axis on the same horizontal plane, and the rotating column 30 forms a z axis on the longitudinal bracket 20 and forms a three-dimensional positioning and adjustment structure with the xy axis.

[0049] The longitudinal support 20 and the rotating column 30 are respectively moved horizontally along the xy axis to adjust the horizontal distance, and the rotating column 30 and the stabilizing arm 32 are moved along the z axis to adjust the vertical distance.

[0050] The horizontal bracket 10 and the vertical bracket 20 form an xy-axis adjustment range, and cooperate with the rotating column 30 to form an xyz-axis three-dimensional range. The rotating column 30 has a built-in hydraulic drive mechanism, which drives the boom 31 to adjust its height.

[0051] like Figure 1 , Figure 2 and Figure 3 As shown, a fixed hydraulic support group 12 is provided under the transverse support 10 and the longitudinal support 20, and at least two groups of mobile hydraulic support groups 13 are provided under the transverse support 10. The fixed hydraulic support group 12 and the mobile hydraulic support group 13 together constitute a multi-point support structure. At least two groups of mobile hydraulic support groups 13 translate along the length direction of the transverse support 10 and then move alternately to form a walking structure.

[0052] At least two groups of mobile hydraulic support groups 13 are arranged alternately, and one group of mobile hydraulic support groups 13 is lifted after translation, and the other group of mobile hydraulic support groups 13 is lifted after repeated translation, and moves alternately in sequence.

[0053] The cross support 10 is supported at a height by a fixed hydraulic support group 12 , and at least two mobile hydraulic support groups 13 are used to provide auxiliary support to the cross support 10 . The mobile hydraulic support group 13 adjusts the support position by sliding under the cross support 10 .

[0054] During fixed support, the mobile hydraulic support group 13 and the fixed hydraulic support group 12 jointly maintain a relatively horizontal support state for the cross support 10 .

[0055] During the frame moving process, first adjust the height of one of the mobile hydraulic support groups 13 to a suspended state. At this time, the cross bracket 10 is supported by other mobile hydraulic support groups 13 and the fixed hydraulic support group 12, and slide the mobile hydraulic support group 13 to one side for a certain distance, and restore the support of the cross bracket 10 by the mobile hydraulic support group 13. Through the alternating translation support movement of at least two groups of mobile hydraulic support groups 13, the purpose of self-translation is achieved, which is conducive to driving the device to achieve the purpose of movement.

[0056] like Figure 1 and Figure 2 As shown, a hydraulic telescopic arm 34 is provided on the base 21 , a stabilizing arm 32 is provided on the hydraulic telescopic arm 34 , and a movable end of the stabilizing arm 32 is connected to a lifting chain 40 to form a synchronous lifting structure.

[0057] The stabilizing arm 32 is composed of a hydraulic telescopic rod, a fixed end of the stabilizing arm 32 is slidably connected to the hydraulic telescopic arm 34 via a slider, and the stabilizing arm 32 and the slider are hinged via a pin.

[0058] The hydraulic telescopic arm 34 drives the lifting arm 31 to be raised and lowered to adjust the final lifting height of the lifting chain 40. At the same time, the stabilizing arm 32 is connected to the lifting chain 40 through the short chain 41. The lifting chain 40 and the short chain 41 are retracted through the same driving device, thereby driving the stabilizing arm 32 to always act on the lifting object position at one end of the lifting chain 40.

[0059] like Figure 1 , Figure 2 and Figure 3 As shown, a Y-shaped suspension chain 40 is provided on the suspension arm 31, one end of the short chain 41 is connected to one end of the suspension chain 40, and the longitudinal section of the combination of the short chain 41 and the suspension chain 40 forms a Y-shaped structure;

[0060] A reeling mechanism 42 is provided at the end where the lifting chain 40 and the short chain 41 meet. The reeling mechanism 42 includes a main roller 43 provided under the boom 31 for guiding the lifting chain 40, a secondary roller 44 for guiding the short chain 41 is provided on one side of the main roller 43 under the boom 31, and a guide roller 45 is provided at one end of the boom 31 close to the hydraulic telescopic arm 34. After the short chain 41 meets the lifting chain 40, it enters the guide roller 45 and is synchronously reeled.

[0061] The reeling mechanism 42 includes a reeling motor, the output shaft of which is fixedly connected to a reeling shaft via a coupling, and the reeling shaft is connected to the suspension chain 40 and reels it.

[0062] After passing through the guide roller 45, the lifting chain 40 forms a double lifting chain 40 structure, which is beneficial to improving the stability of the lifted object through at least two lifting points. At the same time, a double chain structure is formed with the short chain 41 in the longitudinal direction of the lifting chain 40. The short chain 41 guides the stabilizing arm 32 to increase a contact surface on one side around the lifted object, and a certain thrust is applied to the lifted object through the stabilizing arm 32, which is beneficial to stabilizing the lifted object, reducing shaking during the lifting process, and further improving the stability of the device.

[0063] like Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, one end of the stabilizing arm 32 is hinged with a supporting plate 33 via a pin, and a hook 46 is provided at one end of the lifting chain 40. The supporting plate 33 is in active contact with the lifted object below the hook 46 for stabilization.

[0064] The supporting plate 33 is provided with supporting movable columns 331 arranged in an array at equal intervals. One end of the supporting movable column 331 is connected to the inner wall of the supporting plate 33 through a spring. Multiple groups of supporting movable columns 331 can be flexibly extended and retracted on the supporting plate 33 to form a three-dimensional fitting structure.

[0065] The stabilizing arm 32 drives the supporting plate 33 to stabilize the hoisted object, which helps to reduce shaking during the hoisting process. The elastically retractable supporting movable column 331 makes the supporting plate 33 fit the contour of the object better, thereby improving stability.

[0066] like Figure 1 and Figure 2 As shown, a telescopic bracket 14 is provided on one side of the rotating column 30, and the movable end of the telescopic bracket 14 is fixedly connected to the movable end of the hydraulic telescopic arm 34. The movable end of the telescopic bracket 14 is provided with a support 15, and the support 15 and the boom 31 are synchronously raised and lowered to form a protective structure.

[0067] A reinforcement component 16 connected to the boom 31 is provided under the support 15, and the reinforcement component 16 includes a fixed sleeve 161, in which a fixed rod 162 is movably inserted, a spring is provided at the connection between the fixed sleeve 161 and the fixed rod 162, and one end of the fixed rod 162 is movably connected to the boom 31 through a pin shaft.

[0068] By telescopically extending and retracting the telescopic bracket 14 in sync with the hydraulic telescopic arm 34 , the support 15 and the boom 31 are synchronously lifted and lowered, and the support 15 forms a protective structure above the boom 31 , which helps to reduce the impact of falling materials in the well on the operation of the boom 31 during underground operations in the coal mine, and helps to maintain a safe working environment for the boom 31 .

[0069] At the same time, the support 15 and the boom 31 are connected by the reinforcement assembly 16, which helps to reduce the shaking of the boom 31 during the lifting process and helps to improve the stability of the operation of the boom 31.

[0070] like Figure 1 , Figure 2 and Figure 5 As shown, the fixed hydraulic support group 12 includes fixed hydraulic cylinders 121 fixedly installed on both sides below the cross support 10, and the output ends of the fixed hydraulic cylinders 121 are hingedly connected to the bottom plate 122 through pins.

[0071] The mobile hydraulic support group 13 includes a mobile hydraulic cylinder 131, a fixed block 132 and a pedal 133. The output end of the mobile hydraulic cylinder 131 is movably connected to the pedal 133 through the fixed block 132. A two-way hydraulic cylinder 134 fixedly installed under the fixed block 132 is arranged in the pedal 133. The two ends of the two-way hydraulic cylinder 134 are respectively connected to the two ends of the pedal 133. The pedal 133 translates at the output end of the mobile hydraulic cylinder 131 along the movement direction of the two-way hydraulic cylinder 134 to form a walking structure.

[0072] The multi-point support structure formed by the fixed hydraulic support group 12 and the mobile hydraulic support group 13 can better adapt to different ground environments. Compared with the traditional support plane placed directly on the ground, it can reduce the instability of the hydraulic lifting device caused by the low ground flatness.

[0073] The mobile hydraulic support group 13 is slidably connected to the cross bracket 10 via a slide rail, and a hydraulic drive mechanism is provided at the connection between the cross bracket 10 and the slide rail to drive the cross bracket 10 to translate on the mobile hydraulic support group 13 via the slide rail.

[0074] At the same time, through the alternating movement of multiple groups of mobile hydraulic support groups 13, the purpose of movement can be achieved, the distance adjustment range of the device can be further expanded, the use of frame moving equipment can be reduced, and the purpose of self-movement can be achieved. The pedal 133 is lifted by the mobile hydraulic cylinder 131, and the pedal 133 is driven to move horizontally in the forward direction and re-supported by the two-way hydraulic cylinder 134.

[0075] At this time, the cross bracket 10 moves to the other side of the multiple mobile hydraulic support groups 13, and is supported by the fixed hydraulic support group 12, and then the mobile hydraulic support group 13 is translated to the other side of the cross bracket 10, and the reciprocating motion is used to achieve the purpose of movement.
