Description

Technical Field

[0001] The utility model relates to the technical field of ecological frame hoisting, in particular to an ecological frame sling. Background Art

[0002] In water conservancy engineering operations such as riverbank and coast protection, a considerable number of facing blocks need to be installed on the slope, such as Figure 4 the precast tiled ecological frame shown, so as to reduce the impact of water waves on the slope, avoid the loss of slope soil, ensure the stability of the slope structure, and at the same time play a role in improving the environment.

[0003] At present, for the hoisting of precast tiled ecological frames, ropes are mostly used to directly bind and then hoist them to the designed position, and then the shackle is manually operated. Since the precast concrete blocks (precast tiled ecological frames) are heavy, large in size, and a large number need to be installed, the above hoisting method not only has low work efficiency, high overall operation safety risks, but also the blocks are easily damaged.

[0004] In addition, the form of embedded lifting rings is also used, but this requires processing and embedding lifting rings during the precasting of the blocks, which will increase the lifting ring processing process and precasting difficulty and reduce the precasting efficiency.

[0005] Therefore, the current hoisting methods for precast tiled ecological frames all have certain defects and are difficult to meet the requirements of engineering construction. Content of the Utility Model

[0006] The purpose of the utility model is to solve the problems of low efficiency, high operation safety risks, easy damage to the blocks or the need for embedded lifting rings in the hoisting process of precast tiled ecological frames in the prior art, and to propose an ecological frame sling with a new structure.

[0007] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0008] An ecological frame sling includes a cross beam and a hanger structure symmetrically arranged at both ends of the cross beam. The hanger structure includes a hanger and a driving structure. The hanger is rotatably installed at the end of the cross beam. The driving structure includes a connecting rod hinged to the hanger and a pulling rope connected to the connecting rod. The hanger constructs a supporting part with an outward opening for hoisting the ecological frame under the action of the pulling rope. The supporting part includes a supporting arm arranged on the hanger, and the supporting part also includes the end of the cross beam as the upper clamping arm of the supporting part.

[0009] In some embodiments, the ecological frame sling further includes a lifting rope, and both ends of the lifting rope are respectively connected to the hangers located at both ends of the cross beam.

[0010] In some embodiments, the crossbeam is provided with a through hole for controlling the rotation range of the hanger on the crossbeam at the position of the rotationally mounted hanger, the rear wall of the hanger is abutted against the rear wall of the through hole, and the lateral length of the hanger along the length direction of the crossbeam is smaller than the lateral length of the through hole along the length direction of the crossbeam.

[0011] Preferably, a rear limit block abutting against the rear wall of the hanger is provided on the crossbeam at the rear wall of the through hole, and a front limit block abutting against the front wall of the hanger is provided on the crossbeam at the front wall of the through hole.

[0012] In some embodiments, the driving structure also includes a limit frame, which is installed on the crossbeam. A limit hole for controlling the swing amplitude of the connecting rod is constructed between the limit frame and the crossbeam. One end of the connecting rod is hinged to the hanger, and the other end extends out of the limit hole and is connected to one end of a pull rope. The other end of the pull rope passes through the limit frame and the hanger in sequence to form an operating end.

[0013] In some embodiments, a soft pad is provided on the supporting arm, and the top surface of the soft pad is an inclined wall, and the height of the inclined wall gradually increases from the rear end to the front end.

[0014] In some embodiments, the hanger further includes an operating arm disposed at the top, the operating arm is disposed on the same side as the supporting arm, and the hanger is formed into a frame structure with an opening facing outward.

[0015] Compared with the prior art, the ecological frame sling provided by the utility model has the following features:

[0016] Beneficial effects:

[0017] By using the eco-frame lifting device, there is no need to pre-embed lifting rings during the production process of the eco-frame. During lifting, by operating the pull rope, the hanger and the crossbeam can construct a supporting part. By using the supporting part, the supporting arm of the supporting part can be extended into the drainage hole of the eco-frame to support the entire eco-frame, thereby realizing lifting.

[0018] During the entire lifting process, because the lifting frame structure is symmetrically set at both ends of the beam, the eco-frame is evenly stressed during overall lifting, runs smoothly, and does not tilt. The operation is safe with low risk. In addition, during the lifting and unloading and placement processes, smooth lifting and placement can be achieved, and the eco-frame is not easily damaged.

[0019] Compared with the rope binding lifting in the prior art, the ecological frame lifting device of the utility model has a much faster overall speed. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Embodiment:

[0028] Referring to Figures 1 - 4 , an ecological frame sling is provided, which includes a cross - beam 1 and hanging bracket structures symmetrically arranged at both ends of the cross - beam 1. The hanging bracket structure includes a hanging bracket 2 and a driving structure. The hanging bracket 2 is rotatably installed at the end of the cross - beam 1. The driving structure includes a connecting rod 3 hinged to the hanging bracket 2 and a pulling rope 4 connected to the connecting rod 3.

[0029] Since the hanger 2 is rotatably installed at the end of the cross beam 1, when the pulling rope 4 is operated, the hanger 2 can cooperate with the end of the cross beam 1 under the action of the pulling rope 4 to form a supporting part 6 with an opening facing outwards for lifting the ecological frame 5. The supporting part 6 includes a supporting arm 7 arranged on the hanger 2, and the supporting part 6 also includes the end of the cross beam 1 as the upper clamping arm 8 of the supporting part 6. As for the ecological frame 5, drainage holes 9 are respectively arranged on its four side walls. Before lifting, the upper clamping arm 8 is placed on the top wall of the ecological frame at the drainage hole 9, and with the manual pulling of the pulling rope 4, the supporting arm 7 can extend into the drainage hole 9. After lifting, the supporting arm 7 supports the top wall at the drainage hole, thereby realizing the lifting and transportation of the entire ecological frame 5.

[0030] To achieve lifting and transportation, the ecological frame lifting device further includes a lifting rope 10. In this embodiment, the two ends of the lifting rope 10 are respectively connected to the hangers 2 located at both ends of the cross beam 1. When lifting, the hook of the crane can hook the lifting rope 10 to lift and transport the ecological frame 5.

[0031] To control the rotation amplitude of the hanger 2 on the cross beam 1, in this embodiment, a through hole 11 for controlling the rotation amplitude of the hanger 2 on the cross beam 1 is provided at the position where the cross beam 1 rotatably installs the hanger 2. The rear wall of the hanger 2 abuts against the rear wall of the through hole 11, and the lateral length of the hanger 2 along the length direction of the cross beam 1 is smaller than the lateral length of the through hole 11 along the length direction of the cross beam 1. To increase the reliability of controlling the rotation amplitude and increase the contact area, in this embodiment, a rear limiting block 12 that abuts against the rear wall of the hanger 2 is provided on the cross beam 1 at the rear wall of the through hole 11, and a front limiting block 13 that abuts against the front wall of the hanger 2 is provided on the cross beam 1 at the front wall of the through hole 11. It should be noted that the front and rear directions shown herein can be understood as, at the end of the cross beam 1 in this embodiment, the direction close to the center of the cross beam 1 is the rear, and the direction close to the end of the cross beam 1 is the front.

[0032] In this embodiment, to effectively control the swing amplitude of the connecting rod 3, the driving structure further includes a limiting frame 14. The limiting frame 14 is installed on the cross beam 1, and a limiting hole 15 for controlling the swing amplitude of the connecting rod 3 is formed between the limiting frame 14 and the cross beam 1. One end of the connecting rod 3 is hinged to the hanger 2, and the other end extends out of the limiting hole 15 and is connected to one end of the pulling rope 4. The other end of the pulling rope 4 passes through the limiting frame 14 and the hanger 2 in sequence to form an operating end. Through the cooperative setting of the above-mentioned components, when the pulling rope 4 is operated, that is, when the operating end of the pulling rope 4 is pulled, the outer end of the connecting rod 3 is pulled up and finally limited on the upper top wall of the limiting hole 15. At this time, the connecting rod 3 is in a horizontal state. Since the connecting rod 3 is hinged to the hanger 2, under the drive of the connecting rod 3, the hanger 2 is forced to rotate, and the rear wall of the hanger 2 abuts against the rear wall of the through hole 11. At this time, the hanger is in a vertical state. During this process, the supporting arm 7 of the hanger 2 can extend into the drainage hole 9 of the ecological frame 5.

[0033] Consider avoiding damage to the supported part of the ecological frame 5 during hoisting. In this embodiment, a soft pad 16 is provided on the supporting arm 7, and the top surface of the soft pad 16 is an inclined wall, and the height of the inclined wall gradually increases from the rear end to the front end. Specifically, reference can be made to Appendix Figure 2 and Appendix Figure 3 . Of course, in other embodiments, the soft pad 16 can also be the Figure 1 shown in the figure, which is generally similar to a rectangular plate structure and is lapped on the supporting arm 7.

[0034] The hanging frame 2 further includes an operating arm 17 provided at the top. The operating arm 17 is arranged on the same side as the supporting arm 7, and the hanging frame 2 is configured as a frame structure with an opening facing outwards. After the operating arm 17 is arranged, it can assist the pulling rope 4 to force the hanging frame 2 to be vertical, so that the supporting arm 7 extends into the drain hole 9.

[0035] During use, first place the lifting tool into the central hole 18 of the ecological frame 5, and make the end of the cross beam 1, that is, the upper clamping arm 8, press on the top wall of the ecological frame 5. Then pull the operating end of the pulling rope 4 to drive the connecting rod 3 until it remains in a horizontal state. During this process, driven by the connecting rod 3, the supporting arm 7 of the hanging frame 2 extends into the drain hole 9. At this time, lift the lifting rope 10, and the upper top wall of the drain hole 9 presses on the supporting arm 7, and the supporting arm 7 supports the entire ecological frame 5. It should be noted that during hoisting, the supporting arms 7 at both ends of the cross beam 1 are symmetrically arranged to jointly support the entire ecological frame 5, thereby keeping the ecological frame 5 uniformly stressed and the hoisting stable.

[0036] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
