Description

Technical Field

[0001] The invention relates to the technical field related to slings, and in particular to adjustable aluminum plate lifting equipment. Background Art

[0002] C-type slings are mainly used for horizontal lifting of rolled plates. Because of its shape that resembles the letter C, it is called C-type slings. Its lifting and installation process, structure are simple and reasonable, the action is flexible, the use is convenient, and the lifting is safe and reliable. In recent years, the specifications and models of aluminum plates have been constantly changing, and there are many types.

When multiple groups of C-type slings are symmetrically clamped, the mutually symmetrical C-type slings will apply a set of symmetrical extrusion pressures to the aluminum plate under the action of downward traction, causing the aluminum plate to bend and deform under the action of gravity and extrusion pressure.

DETAILED DESCRIPTION

[0028] 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. The present invention will be described in detail with reference to the drawings and in combination with the embodiments.

[0029] In one embodiment of the present invention, see Figures 1 to 9 , an adjustable aluminum plate lifting equipment, comprising four sets of lifting pipes 1, a center of gravity balance component 35, and a lifting component 36;

[0030] The four groups of hoisting tubes 1 are symmetrical to each other, and a group of inner sliding sleeves 2 and a group of outer sliding sleeves 3 are fixedly connected to the outer walls of the hoisting tubes 1, and the inner sliding sleeves 2 and the outer sliding sleeves 3 are vertically arranged with the hoisting tube 1 as the center, and the inner sliding sleeves 2 and the outer sliding sleeves 3 are located in the same plane, the inner sliding sleeves 2 are slidably connected in the outer sliding sleeves 3, and two groups of mutually perpendicular first hydraulic telescopic rods 4 are arranged between the outer sliding sleeves 3, and the mounting ends and driving ends of the two groups of first hydraulic telescopic rods 4 are rotatably connected to the four groups of outer sliding sleeves 3 respectively;

[0031] A second hydraulic telescopic rod 16 is installed in the hoisting pipe 1, and a mounting rod 17 is fixedly connected to the output end of the second hydraulic telescopic rod 16, and a hanger 18 is fixedly connected to the outer wall of the mounting rod 17. A rotating hanging rod 19 is rotatably connected to the hanger 18 through an assembly pin 27, and a connecting column 20 is rotatably connected to the middle of the rotating hanging rod 19, and a lower hanging plate 21 is fixedly connected to the bottom of the connecting column 20, and a clamping head 22 is fixedly connected to one end of the rotating hanging rod 19 close to the lower hanging plate 21, and the clamping head 22 cooperates with the lower hanging plate 21. A damping telescopic rod 24 is fixedly connected to the bottom of the mounting rod 17, and a driving shaft 26 is fixedly connected to the input end of the damping telescopic rod 24. An adjusting slot 25 is fixedly connected to the bottom of the lower hanging plate 21, and the driving shaft 26 is arranged in the adjusting slot 25;

[0032] In the process of lifting the aluminum plate, the present invention first adjusts the relative distance of the four groups of lifting pipes 1 according to the size of the aluminum plate, and the lifting pipes 1 drive the lower hanging plates 21 to move, and then adjusts the relative distance between the lower hanging plates 21 according to the size of the aluminum plate. During the adjustment, the relative sliding adjustment between the inner sliding sleeve 2 and the outer sliding sleeve 3 can be driven by the telescopic adjustment of the first hydraulic telescopic rod 4 to adjust the relative positions of the four groups of lifting pipes 1 while supporting and connecting the four groups of lifting pipes 1. After the adjustment is completed, the four groups of lifting pipes 1 are fixedly supported by the relative fixation of the first hydraulic telescopic rod 4 after stabilization, thereby avoiding relative movement of the lifting pipes 1 during the lifting process, which affects the stability of the lifting of the aluminum plate.

[0033] After the adjustment is completed, the present invention drives the lower hanging plate 21 to descend through the second hydraulic telescopic rod 16, so that the lower hanging plate 21 is fitted to the bottom of the aluminum plate, and the assembly pin 27 is pulled out at the same time. At this time, the hanging bracket 18 loses connection with the rotating hanging rod 19. At this time, the rotating hanging rod 19 can be rotated to rotate and lift the clamping head 22, and at the same time, the damping telescopic rod 24 is controlled to shrink, thereby driving the lower hanging plate 21 to tilt downward, and then the lower hanging plate 21 can be inserted into the bottom of the corner of the aluminum plate. At this time, the aluminum plate is set between the lower hanging plate 21 and the clamping head 22, and then the rotating hanging rod 19 is rotated and closed to make the rotating hanging rod 19 overlap with the hanging bracket 18 again, and the assembly pin 27 is inserted back, and then the damping telescopic rod 24 is controlled to extend. At this time, the damping telescopic rod 24 is The mutual cooperation between the driving shaft 26 and the adjusting groove 25 drives the lower hanging plate 21 to rotate and rise with the rotating connection between the rotating hanging rod 19 and the connecting column 20 as the center, and the connecting column 20 drives the lower hanging plate 21 to rise, and then the lower hanging plate 21 and the clamping head 22 cooperate with each other to clamp the corners of the aluminum plate, and then the damping telescopic rod 24 continues to extend. At this time, the damping telescopic rod 24 applies an elastic driving force to the lower hanging plate 21, and the elastic driving force is converted into a clamping force for the corners of the aluminum plate through the mutual cooperation between the lower hanging plate 21 and the clamping head 22, thereby realizing the tight clamping of the aluminum plate, and then with the lifting of the equipment, the aluminum plate is relatively tensioned and fixed under the clamping traction of the lower hanging plate 21 and the clamping head 22, thereby avoiding bending and deformation caused during the lifting of the aluminum plate.

[0034] In one case of this embodiment, see Figure 8 The clamping head 22 is provided with anti-skid patterns 23. The present invention improves the friction between the clamping head 22 and the aluminum plate by providing the anti-skid patterns 23, thereby improving the stability of the clamping head 22 and the lower bracket 18 in clamping the aluminum plate.

[0035] In one case of this embodiment, see Figure 6 to Figure 9 The center of gravity balance component 35 is installed between the hoisting pipes 1, and is used to control the telescopic operation of the first hydraulic telescopic rod 4 and the second hydraulic telescopic rod 16, while adjusting the damping force of the damping telescopic rod 24, and as the hoisting pipes 1 are contracted or expanded, the center of gravity balance component 35 is always stable at the symmetric center of the four groups of hoisting pipes 1;

[0036] The center of gravity balance component 35 includes a positioning base 11 arranged at the symmetrical center of the lifting pipe 1, a hydraulic cylinder 14 is fixedly installed on the positioning base 11, a control pump 15 is installed on the hydraulic cylinder 14, and the control pump 15 is connected to the first hydraulic telescopic rod 4, the second hydraulic telescopic rod 16, and the damping telescopic rod 24. A group of upper gear racks 5 and a group of lower gear racks 6 are fixedly connected to the outer wall of the lifting pipe 1. The upper gear racks 5 and the lower gear racks 6 are vertically arranged with the lifting pipe 1 as the center. The adjacent upper gear racks 5 and the lower gear racks 6 are connected to the outer wall of the lifting pipe 1. A positioning gear 7 is provided between the wheel frames 6, the positioning gear 7 is synchronously meshed with the upper gear frame 5 and the lower gear frame 6, and the positioning gear 7 is arranged in the symmetric plane of the hoisting pipe 1, the positioning gear 7 is fixedly connected with a positioning sleeve 8, and a sliding telescopic groove 9 is arranged in the positioning sleeve 8, and two groups of mutually perpendicular positioning bearings 12 are fixedly connected in the positioning base 11, and a positioning rod 13 is fixedly connected in the positioning bearing 12, and the two ends of the positioning rod 13 are rotatably connected with a connecting block 10, and the connecting block 10 is slidably connected with the sliding telescopic groove 9;

[0037] The center of gravity balancing assembly 35 first controls the hydraulic cylinder 14 through the control pump 15, and controls the first hydraulic telescopic rod 4, the second hydraulic telescopic rod 16, and the damping telescopic rod 24 respectively through programming the control pump 15, thereby realizing programmable control of the equipment, and through the large weight of the hydraulic cylinder 14, and the setting that the center of gravity of the hydraulic cylinder 14 and the center of symmetry of the equipment are located on the same axis, the influence of external forces on the equipment is reduced, and the overall stability of the equipment is improved;

[0038] When the first hydraulic telescopic rod 4 and the second hydraulic telescopic rod 16 are being extended and retracted, the hoisting tube 1 is being contracted and expanded synchronously. When the hoisting tube 1 is being contracted and expanded, the hoisting tube 1 drives the upper gear frame 5 and the lower gear frame 6 to move synchronously. At this time, the positioning gear 7 is synchronously meshed with the upper gear frame 5 and the lower gear frame 6 to achieve the relative synchronous movement between the positioning gear 7 and the upper gear frame 5 and the lower gear frame 6. That is, although the relative positions of the upper gear frame 5, the lower gear frame 6 and the positioning gear 7 are changed, the relative position between the positioning gear 7 and the symmetric plane of the equipment remains unchanged. When the position between the two relatively symmetrical groups of positioning gears 7 changes, the adaptive positioning of the hydraulic cylinder 14 is achieved through the sliding connection between the positioning sleeve 8 and the connecting block 10, and the rotational connection between the positioning rod 13 and the connecting block 10, and the positioning gear 7 is relatively fixed to the symmetry plane, thereby achieving a relatively stable setting of the center of gravity of the hydraulic cylinder 14 and the center of symmetry of the four groups of lifting pipes 1, thereby avoiding the tilt of the equipment caused by the change of the center of gravity during the expansion and contraction process of the equipment, that is, no matter how the equipment is adjusted, the center of gravity of the equipment as a whole remains unchanged, thereby improving the stability of the equipment lifting.

[0039] In one case of this embodiment, see Figure 4 and Figure 5, the hoisting assembly 36 is installed on the top of the four groups of hoisting pipes 1, and is used to connect the hoisting pipes 1 with the hoisting equipment;

[0040] The hoisting assembly 36 includes a hoisting frame 32, a hoisting hole 31 is fixedly connected to the bottom of the hoisting frame 32 and the top of the hoisting pipe 1, and the hoisting holes 31 are connected by a steel cable 33. A lifting ring 34 is fixedly connected to the top of the hoisting frame 32. The hoisting assembly 36 also includes an outer support frame 28 fixedly connected to the bottom of the hoisting pipe 1, and a support leg 29 is fixedly connected to the outer support frame 28. A universal wheel 30 is installed at the bottom of the support leg 29;

[0041] The hoisting assembly 36 firstly supports the hoisting frame 32 in a rolling manner through the arrangement of the universal wheels 30 and the support legs 29, and at the same time, the support legs 29 are extended to the outside of the hoisting frame 32 through the arrangement of the outer support frame 28, thereby avoiding interference between the support legs 29 and the hoisting equipment and the plate, which affects the hoisting of the aluminum plate by the equipment, and then the position of the equipment on the ground can be freely transferred through the arrangement of the universal wheels 30, thereby avoiding the equipment tilting caused by the misalignment between the equipment and the hoisting equipment during the hoisting process, which affects the balance of the equipment hoisting, and then the hoisting assembly 36 can be connected to the hoisting equipment through the lifting ring 34, and then the hoisting frame 32 is driven to rise and fall through the hoisting equipment, and the hoisting frame 32 drives the hoisting pipe 1 to rise and fall through the connection between the steel cable 33 and the hoisting hole 31, thereby realizing the lifting of the aluminum plate, and after the aluminum plate is clamped, since the four groups of hoisting pipes 1 are relatively fixed, the oblique traction force of the steel cable 33 will not drive the hoisting pipes 1 to retract each other, thereby avoiding the aluminum plate from being bent and deformed under stress during the lifting process.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
