Description

Technical Field

[0001] The utility model relates to hoisting equipment, in particular to a hoisting device. Background Art

[0002] The lifting device is used in all walks of life. The existing traveling crane includes a translation beam, a mobile platform is arranged on the beam to cooperate with the beam to form a two-axis translation structure, and a pipe twisting mechanism is arranged on the mobile platform to realize the upper and lower lifting mechanism. The traveling crane is mostly used inside the factory building.

[0003] The current overhead crane is composed of a hook and a pulley block. Taking into account the safety of lifting, the center of gravity of the load must be considered, so the shape and quantity of the hoisted objects are relatively limited; furthermore, after the tubular hoist is connected with the pulley block to make the hook, the distance between the steel cables is very small, almost like a sling. When the height is high and the moving speed is slightly faster, the hook with the heavy object mounted on it is prone to swing. The swing range of the hook will affect the safety range of the working area, so for safety reasons, the swing amplitude of the hook must also be controlled.

[0004] In view of the above problems, it is necessary to develop a lifting device whose center of gravity is not easily affected and which is not prone to swinging in a high lifting stroke environment. Utility Model Content

[0005] In view of the above-mentioned defects, the utility model proposes a lifting device, which has a structural design in which the center of gravity is not easily affected by the mounting and the swing phenomenon is not easy to occur in a high lifting stroke environment.

[0006] To achieve this purpose, the utility model adopts the following technical solutions:

[0007] A lifting device comprises a translation assembly, a lifting mechanism and a sling assembly; the translation assembly comprises two groups of long beams arranged in the same plane, and the two ends of the two groups of long beams are respectively fixedly installed with the walking mechanisms on both sides to form a frame shape;

[0008] The sling assembly is in the shape of a rectangular long frame, and two sets of lifting lower pulleys are installed in the space between the sling assembly; a plurality of short beams are also arranged at intervals in the frame of the sling assembly, and hooks are installed on the lower surface of the short beams;

[0009] At least two groups of the lifting mechanisms are arranged and installed between two groups of long beams, and the two groups of the lifting mechanisms are fixedly installed close to the walking mechanisms on both sides. The two groups of lifting lower pulley blocks are respectively located directly below the two groups of the lifting mechanisms, and the lifting lower pulley blocks are respectively connected to the lifting mechanisms directly above through steel cables to form lifting pulley blocks.

[0010] Preferably, the lifting mechanism is a pipe-hinged lifting mechanism, and an upper fixed pulley is provided on one side of the lifting mechanism;

[0011] The two ends of the steel cable are located at the pipe hinge of the lifting mechanism, and the retracted and released steel cable is in a closed loop;

[0012] The lifting lower pulley assembly comprises two lower pulleys arranged in parallel and at intervals, and two steel cables are respectively sleeved on the two lower pulleys of the lifting lower pulley assembly, and then the circular arc section of the steel cable is sleeved upward on the upper fixed pulley.

[0013] Preferably, it further comprises an anti-sway device, wherein the anti-sway device is two sets of horizontal frames arranged vertically at intervals, and the anti-sway device is fixedly mounted on the sling assembly;

[0014] There are cross frames on both sides of the upper steel cables of the two lower pulleys of the lifting pulley block. When in a swinging state, the steel cables will interfere with the cross frames to reduce the swing amplitude.

[0015] The upper end of the horizontal frame is provided with a rotating shaft with an axis arranged along the length direction of the sling assembly.

[0016] Preferably, the traveling mechanism is in the shape of a short crossbeam, and rail wheels are installed at the bottom of both ends of the traveling mechanism, and at least one rail wheel is installed with a driving device.

[0017] Further, the upper end of the hook is rotatably mounted on the short crossbeam;

[0018] The rotation axis direction of the hook is consistent with the rotation axis direction of the pulley.

[0019] Furthermore, it also includes a mounting seat, and the lifting lower pulley block is mounted on the translation assembly through the mounting seat;

[0020] The mounting seat is a frame that can be accommodated between two long beams, and the lifting mechanism is fixedly mounted on the mounting seat;

[0021] The long cross beams are provided with a plurality of mounting bosses on the side surfaces opposite to the long cross beams, and the mounting seats are fixedly mounted on the mounting bosses of the two long cross beams by bolts.

[0022] Furthermore, it also includes a buffer block, and the front and rear ends of the walking mechanism are both equipped with a buffer block;

[0023] A buffer block is also installed on the position of the sling assembly corresponding to the upper mounting seat.

[0024] The technical solution provided by the embodiment of the present application may include the following beneficial effects: the lifting device proposed in this solution first lacks a device for longitudinal movement, and only has two actions: lateral translation and lifting and lowering. Therefore, restraining the lateral swing can play an anti-swinging effect; the solution disperses the center of gravity of the longitudinal swing by setting two sets of lifting mechanisms at intervals, and cooperates with the rectangular long frame-shaped sling assembly to eliminate the longitudinal swing; in terms of lateral swing, since the lifting mechanism cooperates with the lifting lower pulley group and adopts an interval steel cable group, the center of gravity is also dispersed, and the multi-hook sling that is not easy to swing and is dispersedly hung further disperses the center of gravity, improves the conditions required for swinging, and does not easily swing. In addition, the sling assembly has multiple hooks, so that the efficiency of the single work of the device can be improved, and multiple hanging points are also convenient for lifting special-shaped objects.

DETAILED DESCRIPTION

[0031] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0032] In the description of the present invention, it should be understood that the terms "length", "middle", "upper", "lower", "left", "right", "top", "bottom", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0033] like Figure 1 and 5 As shown, a lifting device includes a translation assembly 100, a lifting mechanism 200 and a sling assembly 300; the translation assembly 100 includes two groups of long beams 110 arranged in the same plane, and the two ends of the two groups of long beams 110 are respectively fixedly installed with the walking mechanisms 120 on both sides to form a frame shape;

[0034] The sling assembly 300 is in the shape of a rectangular long frame, and two sets of lifting lower pulleys 400 are installed in the space between the sling assembly 300; a plurality of short beams are also arranged in the frame of the sling assembly 300, and a hook 310 is installed on the lower surface of the short beam;

[0035] At least two groups of the lifting mechanisms 200 are arranged and installed between the two groups of long beams 110. The two groups of the lifting mechanisms 200 are fixedly installed close to the walking mechanisms 120 on both sides. The two groups of lifting lower pulley groups 400 are respectively located directly below the two groups of the lifting mechanisms 200. The lifting lower pulley groups 400 are respectively connected to the lifting mechanisms 200 directly above to form lifting pulley groups through steel cables.

[0036] The lifting device proposed in this scheme lacks a device for longitudinal movement, and only has two actions: lateral translation and lifting. Therefore, restraining the lateral swing can play an anti-swing effect. The scheme disperses the center of gravity of the longitudinal swing by setting two sets of lifting mechanisms 200 at intervals, and cooperates with the rectangular long frame-shaped sling assembly 300, so as to eliminate the longitudinal swing. In terms of lateral swing, since the lifting mechanism 200 cooperates with the lifting lower pulley assembly 400, an interval of steel cable groups is used, which also disperses the center of gravity. In combination with the multi-hook sling that is not easy to swing and is dispersedly hung, the center of gravity is further dispersed, the conditions required for swinging are improved, and swinging will not occur easily. In addition, the sling assembly 300 has multiple hooks 310, so that the efficiency of the single work of the device can be improved, and multiple hanging points are also convenient for hoisting special-shaped objects.

[0037] like Figure 2 and 4 As shown, the lifting mechanism 200 is a pipe-hinged lifting mechanism, and an upper fixed pulley 210 is provided on one side of the lifting mechanism 200;

[0038] Both ends of the steel cable are located at the pipe hinge of the lifting mechanism 200, and the retracted and released steel cable is in a closed loop;

[0039] The lifting lower pulley assembly 400 is composed of two lower pulleys 410 spaced in parallel. Two steel cables are respectively sleeved on the two lower pulleys 410 of the lifting lower pulley assembly 400, and then the arc section of the steel cable is sleeved on the upper fixed pulley 210 upward.

[0040] Compared with single or double-strand wire ropes, double-row four-strand wire ropes have a larger center of gravity range and are less prone to shaking.

[0041] like Figure 5 As shown, it also includes an anti-sway device 500, the anti-sway device 500 is two sets of horizontal frames arranged vertically at intervals, and the anti-sway device 500 is fixedly installed on the hanger assembly 300;

[0042] Both sides of the upper steel cables of the two lower pulleys of the lifting pulley block 400 are provided with cross frames, and the steel cables will interfere with the cross frames in the swinging state to reduce the swing amplitude;

[0043] A rotating shaft having an axis arranged along the length direction of the sling assembly 300 is installed at the upper end of the horizontal frame.

[0044] The anti-sway device 500 is provided to prevent lateral swing.

[0045] like Figure 2 As shown, the walking mechanism 120 is in the shape of a short beam, and rail wheels are installed at the bottom of both ends of the walking mechanism 120, and at least one rail wheel is installed with a driving device.

[0046] Both sets of walking mechanisms 120 are provided with driving devices.

[0047] like Figure 5 As shown, the upper end of the hook 310 is rotatably mounted on the short beam;

[0048] The rotation axis direction of the hook 310 is consistent with the rotation axis direction of the pulley.

[0049] After the hook is mounted, it will swing, but the direction of the hook's swing is longitudinal. This design is also to prevent the swing of the fixed hook from being transmitted to the steel cable. The longitudinal degree of freedom is used to release it to avoid the overall lateral swinging force.

[0050] like Figure 2 As shown, it also includes a mounting seat 600, and the lifting pulley assembly 400 is mounted on the translation assembly 100 through the mounting seat 600;

[0051] The mounting seat 600 is a frame that can be accommodated between the two long beams 110, and the lifting mechanism 200 is fixedly installed on the mounting seat 600;

[0052] The long beams 110 are provided with a plurality of mounting bosses 130 on the opposite sides of the long beams 110 , and the mounting seat 600 is fixedly mounted on the mounting bosses 130 of the two long beams 110 by means of bolts.

[0053] By providing the mounting base 600 , the levelness can be adjusted.

[0054] As a supplement to the above technology, a buffer block is also included, and the front and rear ends of the walking mechanism 120 are both equipped with a buffer block;

[0055] A buffer block is also installed on the position of the hanger assembly 300 corresponding to the upper mounting seat 600.

[0056] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the present invention.
