Description

Technical Field

[0001] This utility model relates to the field of stone processing technology, and in particular to a hoisting device for efficiently handling stone. Background Technology

[0002] With the development of architectural design, stone decoration has been widely used in decoration engineering and material technology, especially in the interior and exterior decoration of projects such as garden landscapes, municipal works, and building construction. After the stone is processed and shaped, it will be transferred to the required location for use. During the loading or transfer of the stone, hoisting tools are needed for lifting and moving. In traditional hoisting methods, large pieces of stone are usually tied with steel wire ropes and then lifted and moved by a crane. When using these hoisting tools, loading and unloading require special personnel to hook and unhook, which is time-consuming, requires a lot of manpower, and is not economical.

[0003] Chinese patent CN203653099U discloses a cantilever crane, which includes a column, a slewing arm, and an electric hoist for lifting objects. It also includes a telescopic arm, which is installed below the slewing arm and can be driven by a first drive mechanism to slide back and forth along the length of the slewing arm. The electric hoist is installed below the telescopic arm and can also slide back and forth. In use, the cantilever crane moves the lifted workpiece via the electric hoist. However, the cantilever arm can only rotate circumferentially along the column and cannot rotate on its own, resulting in poor flexibility. Furthermore, the safety of the single-arm support mechanism needs improvement. Utility Model Content

[0028] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0029] In the attached diagram, all identical reference numerals refer to the same components.

[0030] like Figure 1-5 As shown, this utility model provides a high-efficiency hoisting device for handling stone materials, comprising:

[0031] A fixed column 10 has a cylinder seat 11 rotatably connected to its top end;

[0032] The lifting device 20 is installed on the side of the cylinder seat 11, and its lower end is hinged to the cylinder seat 11, and its top is hinged to the main arm 30.

[0033] The main boom 30 is hinged at one end to the upper end of the lifting device 20 and its middle part is pivotally connected to the top of the cylinder seat 11 through a deep groove ball bearing. The other end is hinged to the hanging seat 40.

[0034] The auxiliary lever arm 50 is set parallel to the main lever arm 30, and its two ends are respectively hinged to the cylinder seat 11 and the end of the hanger 40;

[0035] The upper arm 60 is pivotally connected to the hanger 40 at its upper end via a deep groove ball bearing, and the lower arm 70 is pivotally connected to the lower end of the upper arm 60 via a deep groove ball bearing.

[0036] The lower arm 70 has a hook device 80 fixed at its lower end for fixing the stone. The hook device 80 includes two cross-arranged scissor clamps 81.

[0037] The method of using this utility model is as follows:

[0038] 1. After receiving the instruction from the manual control switch, the PLC in the control box 23 controls the movable end of the lifting cylinder 21 to extend and controls the end of the main arm 30 connected to the upper arm 60 to descend.

[0039] 2. The movable hook device 80 moves toward the stone slab to be lifted. During this process, the cylinder seat 11, upper arm 60 and lower arm 70 can all rotate freely and flexibly to adjust the position and angle of the anti-slip pad 82 on the hook device 80, so as to conveniently clamp the stone slab.

[0040] 3. During the adjustment of the position and angle of the hook device 80, instructions can be sent to the PLC through the manual control switch to control the main brake cylinder 12, the upper arm brake cylinder 43 and the lower arm brake cylinder 72 to control the contact between the brake pads and the brake disc, so that the rotating mechanism can be flexibly stopped at any angle.

[0041] For further details, please refer to the appendix. Figure 1-2A main brake cylinder 12 is fixedly connected to the bottom surface of the cylinder seat 11; a main brake pad 13 for decelerating the rotation of the cylinder seat 11 is fixedly connected to the movable end of the main brake cylinder 12; a main brake disc 14 is bolted onto the outer circle of the top of the fixed column 10, and its upper surface contacts the main brake pad 13 for braking the rotation of the cylinder seat 11; a main limiting sleeve 15 for limiting the rotation of the main brake pad 13 is fixed on the main brake disc 14.

[0042] In this embodiment, the cylinder seat 11 and the fixed column 10 are rotatably connected by a bearing, so that the cylinder seat 11 can rotate around the fixed column 10. When the movable end of the main brake cylinder 12 extends, it controls the main brake pad 13 to contact the surface of the main brake disc 14. In addition, when used in conjunction with the main limiting sleeve 15, the positioning and limiting of the cylinder seat 11 during rotation can be realized, ensuring the safety of the cylinder seat 11 during rotation.

[0043] For further details, please refer to the appendix. Figure 2-3 The lifting device 20 includes: a lifting cylinder 21, whose fixed end is hinged to the cylinder seat 11 and whose movable end is hinged to the end of the main arm 30; an air tank 22, which is fixed to one side of the cylinder seat 11 by a bracket; a control box 23, whose bottom is fixed to the other side of the cylinder seat 11, and which is equipped with a PLC for controlling the air intake of each cylinder, the PLC being connected to a manual control switch via a cable; and a limit rod 24, whose two ends are respectively hinged to the lifting cylinder 21 and the main arm 30, for limiting the lifting of the main arm 30.

[0044] In this embodiment, when the movable end of the lifting cylinder 21 extends, it drives the end of the main arm 30 near the cylinder to rise and the end away from the cylinder to fall, thereby realizing the downward movement of the main arm 30, which in turn drives the hook device 80 to move downward to hook the stone slab. In addition, since a limiting rod 24 is provided, and an adjustable fastening nut is provided at the hinge position between the upper end of the limiting rod 24 and the main arm 30, the position of the fastening nut on the limiting rod 24 can be set to control the extreme position during the up and down movement of the main arm 30, thereby preventing the main arm 30 from exceeding the extreme position when it descends, and ensuring the safety of the hoisting.

[0045] Furthermore, the suspension base 40 includes: a porous bearing housing 41, one side of which is connected to the main arm 30 and the auxiliary arm 50 via bearings; an upper shaft 42, the shaft of which is connected to the center of the porous bearing housing 41 via bearings, and its bottom is fixed to the upper arm 60; an upper arm brake cylinder 43, the base of which is fixed to the upper surface of the upper arm 60, and an upper arm brake pad 44 is fixedly connected to its movable end; and an upper arm brake disc 45, which is fixed to the bottom end of the porous bearing housing 41, and its upper surface contacts the upper arm brake pad 44 for rotating braking of the upper arm 60.

[0046] In this embodiment, one side of the porous bearing seat 41 is connected to the main arm 30 and the auxiliary arm 50 via bearings, thereby connecting the auxiliary arm 50 and the main arm 30 into a whole, enhancing the structural strength and load-bearing capacity of the entire main arm, preventing bending or breakage of the main arm, and improving the stability and safety of the lifting device. The upper shaft 42 is connected to the center of the porous bearing seat 41 via bearings, and its bottom is fixed to the upper arm 60, thus realizing the rotatable function of the upper arm 60 relative to the porous bearing seat 41. At the same time, the upper arm brake pad 44, driven by the upper arm brake cylinder 43, contacts the surface of the upper arm brake disc 45, realizing the rotation and braking functions of the upper arm 60, ensuring both the rotational flexibility and safety of the upper arm 60.

[0047] Furthermore, the lower arm 70 includes: a lower arm brake disc 71, fixed on the outer circumference of the bottom of the upper arm 60; a lower arm brake cylinder 72, the base of which is fixed on the outer circumference of the upper end of the lower arm 70; a lower arm brake pad 73, the bottom of which is fixed on the movable end of the lower arm brake cylinder 72 and contacts the upper surface of the lower arm brake disc 71 for rotational braking of the lower arm 70; and a lower arm limiting sleeve 74, which is fixed on the bottom surface of the lower arm brake disc 71 and is used to limit the rotation angle of the lower arm 70.

[0048] In this embodiment, the lower arm 70 and the upper arm 60 are rotatably connected by bearings, increasing the flexibility of the lower arm 70 and facilitating the adjustment of the lifting angle by the hook device 80, thereby improving lifting efficiency. When the movable end of the lower arm brake cylinder 72 on the lower arm 70 extends, the surface of the lower arm brake pad 73 contacts the upper surface of the lower arm brake disc 71, allowing the lower arm 70 to rotate and brake at any position, preventing the hook device 80 from rotating freely and improving the safety of the lifting operation.

[0049] Furthermore, the scissor clip 81 is fixedly connected to the bottom end of the lower arm 70, and the scissor clips 81 are cross-shaped in the middle and connected together by a pivot. Anti-slip pads 82 are fixedly connected to the bottom of the scissor clips 81. The anti-slip pads 82 are L-shaped and made of rubber with serrated textures on the surface to increase friction.

[0050] This utility model is a high-efficiency hoisting device for handling stone. By setting a three-section rotatable structure, it achieves a high degree of flexibility in the hook device. At the same time, a brake and limit structure are set at each rotatable position to enhance the stability and safety of the hoisting device.

[0051] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
