DETAILED DESCRIPTION

[0019] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other.

[0020] like Figures 1 to 6 In one embodiment of the cultural relics restoration lifting workbench of the utility model shown, two support frames 2 are arranged at intervals on the base 1, a mounting frame 3 is arranged on the top of the two support frames 2, and a table top 4; the lower part of the table top 4 is provided with a first hinge shaft 41 and a second hinge shaft 42 parallel to each other, and at least two supporting devices 5 are arranged at intervals to drive one side of the table top 4 to rise and fall; the first hinge shaft 41 is hinged on one side of the mounting frame 3; the supporting device 5 includes a driving motor 51 with a reducer installed on the mounting frame 3, a driving disk 52 whose center is connected to the output shaft of the driving motor 51, and a protruding rod 53 arranged on the side of the driving disk 52 away from the driving motor 51; a fifth connecting rod 54 with its two ends hinged on the second hinge shaft 42 and the protruding rod 53 respectively; the axis of the protruding rod 53 does not coincide with the axis of the output shaft of the driving motor 51. A drive motor with a reducer is used to support one side of the table through the drive disc and the fifth connecting rod, and the entire table is supported in a short stroke, so that staff can observe and repair large paper cultural relics on one side, reducing the risk of cultural relics being crushed during work and avoiding the risk of cultural relics shifting and sliding.

[0021] Specifically, the lifting device 6 includes a connecting rod assembly 7 connecting the table 4 and the base 1, a telescopic cylinder 8 whose ends are respectively hinged on the connecting rod assembly 7 and the base 1; the connecting rod assembly 7 includes a first connecting rod 71 with one end fixed to the base 1, a second connecting rod 72 with its top end fixed to the mounting frame 3; a third connecting rod 73 with its ends hinged on the first connecting rod 71 and the second connecting rod 72 respectively; a fourth connecting rod 74 with its ends hinged on the first connecting rod 71 and the second connecting rod 72 respectively; the first connecting rod 71, the second connecting rod 72, the third connecting rod 73, and the fourth connecting rod 74 form a parallelogram. By designing a lifting device that cooperates with the telescopic cylinder and the parallelogram, the stable lifting of the table is ensured, the height of the table is adjusted in time according to the needs of the staff, and by supporting one side of the table and supporting the entire table for a short distance, the staff can perform overall observation and repair operations on large paper cultural relics on one side.

[0022] Specifically, the third connecting rod 73 is placed on the upper part of the fourth connecting rod 74; the fourth connecting rod 74 is provided with a through slot 741 for the telescopic cylinder 8 to pass through. The telescopic cylinder connected to the upper connecting rod ensures stable support for the workbench, achieving a larger tabletop lifting stroke without increasing equipment.

[0023] Specifically, the first connecting rod 71 is vertically fixed on the base 1; the second connecting rod 72 is vertically fixed on the mounting frame 3; the first connecting rod 71 and the second connecting rod 72 are equal in length.

[0024] Specifically, the table top 4 is provided with an inclined movable area 9 which is less than 1 / 3 of its area; the inclined movable area 9 is provided with a movable plate 91 which can be lifted on one side and a lifting device 92 which drives the other side of the movable plate 91 to lift; one end of the movable plate 91 close to the first hinge shaft 41 is hinged to the table top 4.

[0025] Specifically, the lifting device 92 includes a sixth connecting rod 95 hinged at both ends to the movable end of the movable plate 91 and the movable block 93, respectively; a driving device 94 that drives the movable block 93 to move horizontally back and forth; the driving device 94 includes a slide 941 perpendicular to the axis of the third hinge shaft, a sliding seat 942 that can slide back and forth within the slide 941, and an electric screw 943 that drives the sliding seat 942 to move; a fourth hinge shaft 944 is provided at the lower portion of the movable plate 91 to which the sixth connecting rod 95 is hinged; and a fifth hinge shaft 945 is provided at the other end of the sixth connecting rod 95 on the sliding seat 942. By designing an electric screw to drive the sliding seat to slide in conjunction with the connecting rod to achieve a large-stroke lifting operation for the movable plate, when performing complex partial restoration of paper cultural relics, the cultural relics can be placed on the movable plate, and the staff can directly repair them at close range, reducing the wear and tear on the waist caused by bending over during work, and reducing the staff's workload.

[0026] Working principle: The staff selects a suitable working area according to the cultural relics to be repaired and spreads the paper cultural relics on the table. The staff starts the telescopic cylinder 8 to push the connecting rod assembly 7, driving the table 4 to rise to a suitable position. The height is adjusted in time according to the needs of the staff to achieve multi-height adjustment, which improves the comfort of the staff in the repair work. The driving motor 51 is started to drive the table 4 to rotate around the first hinge shaft 41. The side of the table 4 away from the staff can be slightly lifted under the action of the supporting device 5. The staff can achieve a larger working range on one side without directly pressing on the cultural relics, reducing the staff's reciprocating To reduce the workload of turning back on both sides, when repairing cultural relics with smaller lengths, the staff can sit on one side of the table 4, start the lifting device 92 to drive the movable plate 91 to lift up one side away from its hinged end, and the electric screw 943 drives the screw to rotate, thereby driving the sliding seat 942 to move along the slide 941, and the movable plate 91 is lifted by the sixth connecting rod 95 which is hinged on the fourth hinge shaft 944 and the fifth hinge shaft 945 at both ends. The appropriate angle is selected for adjustment according to the length of different paper cultural relics, which effectively reduces the risk of staff directly pressing the cultural relics and reduces the workload of staff in repairing paper cultural relics by turning back and forth.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
