Description

Technical Field

[0001] The invention relates to the technical field of logging, in particular to a hanger bracket used for logging. Background Art

[0002] Felling is the first step in felling trees. Felling small-diameter wood or felling in large pieces requires first determining the direction of felling standing trees, clearing obstacles around them, opening a safe path, and then felling the standing trees.

[0003] There are often towering trees growing in natural scenic spots and beside ancient buildings, such as trees with trunks over 40 meters and a breast diameter over 1 meter. Some trees die due to insect pests and natural disasters, so they need to be cut down and removed. The use of traditional logging methods has a great impact on the natural environment and even affects ancient buildings; in other words, traditional logging methods are not suitable for use in specific environments.

[0004] For example, the woodcutting hanger bracket disclosed in the announcement number CN106472245B can significantly reduce sawing time by using the hanger bracket to assist felling trees in special environments, thereby reducing the labor intensity of workers, the amount of sawdust, and the man-hours required for felling. Using the hanger bracket to assist felling trees in special environments can also ensure the quality of wood.

[0005] During use, the hoist bracket for felling wood needs to first use an oil saw or an axe to open two inclined grooves on the tree body for installing two sets of cantilevers. If the wood material is relatively loose, it is necessary to tie steel wires on the upper and lower edges of the inclined grooves to stabilize the inclined grooves and avoid cracking of the inclined grooves when lifting wood.

[0006] In the early stage of using the above device, it is necessary to open a chute at a suitable position on the tree, and then install and set up the entire equipment, which not only increases the workload of the staff, but also reduces the overall logging efficiency. In addition, opening the chute requires certain skills and is inconvenient to use. For this reason, we propose a hanger bracket for logging. Summary of the invention

When the auxiliary ring is resisted by the tree, the auxiliary ring drives the cross bar, so that the cross bar retracts into the fixed ring, and the cross bar drives the slider to move together. When the slider is resisted by the fixed plate, the slider cannot pass through the through hole in the center of the fixed plate, but it will not affect the normal movement of the cross bar.

When fixing trees of different sizes, large trees will resist the auxiliary ring 31 and bring the cross bar 32 into the fixed ring 21 more, and relatively small trees will resist the auxiliary ring 31 and bring the cross bar 32 into the fixed ring 21 less, so that trees of different thicknesses can be fitted and fixed.

[0024] The locking mechanism 4 includes a moving plate 41, which is slidably mounted on a side of the auxiliary ring 31 close to the cross bar 32, a connecting plate 42 is fixed to the side of the moving plate 41 close to the cross bar 32, a resisting spring 43 is fixed to the side of the connecting plate 42 away from the moving plate 41, and one end of the resisting spring 43 away from the connecting plate 42 is fixed to the surface of the cross bar 32, and a hook-shaped tooth 44 is hinged on the side of the moving plate 41 close to the auxiliary ring 31, and the hook-shaped tooth 44 penetrates the auxiliary ring 31, and the moving plate 41, the connecting plate 42, the resisting spring 43 and the hook-shaped tooth 44 are all provided in two groups, and the two groups of moving plates 41, connecting plates 42, resisting springs 43 and hook-shaped teeth 44 are symmetrically arranged with the transverse center line of the cross bar 32 as the symmetry axis. The two groups of connecting plates 42 are hinged with hinge rods 45 on one side close to the cross bar 32. The two groups of hinge rods 45 penetrate the cross bar 32. The two groups of hinge rods 45 are hinged to each other at one end away from the two groups of connecting plates 42. A movable groove 46 is provided on the surface of the cross bar 32. A slider 47 is slidably installed on the inner side of the movable groove 46. A connecting spring 48 is fixed on the inner side of the movable groove 46. The end of the connecting spring 48 away from the movable groove 46 is fixed to the slider 47. A fixing plate 49 is fixed on the inner wall of the fixing ring 21. A through hole 410 is provided in the center of the fixing plate 49. The cross bar 32 penetrates the through hole 410. A supporting plate 411 is fixed on the inner wall of the cross bar 32. The supporting plate 411 is penetrated by the resistance rod 412 and slides with the resistance rod 412 The auxiliary ring 31 is dynamically connected, a spring 413 is fixed on the side of the support plate 411 away from the auxiliary ring 31, and one end of the spring 413 away from the support plate 411 is fixed on the surface of the resistance rod 412, and a support rod 414 is hinged on the surface of the resistance rod 412, and one end of the support rod 414 away from the resistance rod 412 is hinged on a limited tooth plate 415, and the limited tooth plate 415 is slidably installed on the surface of the cross bar 32, and a locking tooth 416 is fixed on the side of the slider 47 close to the limited tooth plate 415. When the auxiliary ring 31 is resisted by the tree, the auxiliary ring 31 drives the cross bar 32, so that the cross bar 32 is retracted into the fixed ring 21, and the cross bar 32 drives the slider 47 to move together. When the slider 47 is resisted by the fixed plate 49, the slider 47 cannot pass through the fixed plate 49 The through hole 410 in the center does not affect the normal movement of the cross bar 32. When the two groups of movable plates 41 and the connecting plate 42 move to the side away from the cross bar 32, the two groups of connecting plates 42 pull the hinged rod 45, so that the two groups of hinged rods 45 are perpendicular to the connecting plate 42. At this time, the hinged rod 45 pushes the contact rod 412 to move to the side away from the auxiliary ring 31, and the contact rod 412 pushes the limiting tooth plate 415 through the support rod 414 to contact the locking tooth 416 on the slider 47. The locking tooth 416 is locked in the limiting tooth plate 415 to limit the slider 47, thereby limiting the cross bar 32, so that the cross bar 32 cannot continue to move, so that the cross bar 32 and the auxiliary ring 31 can stably contact the surface of the tree.

[0025] A square hole 6 is provided on the auxiliary ring 31, and the hook-shaped teeth 44 can pass through the square hole 6. When the movable plate 41 moves to the side away from the cross bar 32, the hook-shaped teeth 44 can be abutted by the inner side of the square hole 6, so that the hook-shaped teeth 44 rotate at the position hinged with the movable plate 41 and get stuck into the surface of the tree. A through hole 7 is provided on the side of the cross bar 32 close to the connecting plate 42, through which the vertical rod 52 can pass without affecting the swing of the vertical rod 52.

[0026] The cross bar 32 and the connecting plate 42 are provided with a limiting assembly 5 for limiting the connecting plate 42. The limiting assembly 5 includes a connecting block 51, which is slidably mounted on the inner side of the moving groove 46 on the surface of the cross bar 32. The side of the cross bar 32 close to the connecting plate 42 is penetrated by a vertical rod 52 and is hinged to the vertical rod 52. A volute spring 53 is fixed on the surface of the vertical rod 52. One end of the volute spring 53 away from the vertical rod 52 is fixed on the inner wall of the cross bar 32. A spring 2 54 is fixed on the inner side of the moving groove 46. The spring 2 54 is away from the moving groove 46. One end of the slot 46 is fixed to the connecting block 51, and one end of the vertical rod 52 close to the connecting plate 42 is hinged to a limiting rod 55. A fixing block 56 is fixed to one end of the vertical rod 52 close to the connecting plate 42. A torsion spring 57 is fixed to the surface of the vertical rod 52. The end of the torsion spring 57 away from the vertical rod 52 is fixed to the limiting rod 55. An L-shaped slot 58 is provided on the side of the connecting plate 42 close to the cross bar 32. The limiting rod 55 can be inserted into the L-shaped slot 58 on the side of the connecting plate 42 close to the cross bar 32 to limit the connecting plate 42. When the cross bar 32 moves and retracts, When the connecting block 51 is in the fixing ring 21, the connecting block 51 is resisted by the fixing ring 21 and cannot extend into the fixing ring 21, so that the connecting block 51 can move in the moving groove 46. When the connecting block 51 moves, it can resist on the vertical rod 52, so that the vertical rod 52 swings at the position hinged with the cross bar 32, and the vertical rod 52 drives the limiting rod 55 to move together, so that the limiting rod 55 can no longer be stuck in the L-shaped slot 58, so as to release the limit of the connecting plate 42. When the connecting block 51 no longer resists the vertical rod 52, the vertical rod 52 can be moved in the spiral spring 5 3, when it is necessary to control the connection plate 42 to be reset, it is only necessary to push the connection plate 42 to move toward the side close to the cross bar 32. When the connection plate 42 contacts the limiting rod 55, the connection plate 42 abuts against the limiting rod 55, so that the limiting rod 55 swings toward the side close to the cross bar 32 at the position where it is hinged with the vertical rod 52. When the limiting rod 55 and the vertical rod 52 are inserted into the L-shaped slot 58, under the action of the torsion spring 57, the limiting rod 55 swings and resets, so that it is stuck in the L-shaped slot 58 to limit the connection plate 42 again.

[0027] First, before the tree to be felled, two fixing rings 21 are put on the tree, and the locking bolts 23 are used to fix the two sets of fixing rings 21 .

[0028] When the fixing ring 21 is fixed, the auxiliary ring 31 on the inner side of the fixing ring 21 is abutted by the surface of the tree, so that the auxiliary ring 31 moves with the cross bar 32, and the cross bar 32 retracts into the fixing ring 21. At this time, the connecting block 51 on the inner side of the moving groove 46 on the surface of the cross bar 32 is abutted by the inner side of the fixing ring 21, and the connecting block 51 cannot extend into the fixing ring 21. The connecting block 51 slides along the moving groove 46 and abuts on the vertical rod 52, so that the vertical rod 52 swings at the position hinged with the cross bar 32, and the vertical rod 52 drives the limiting rod 55 The connecting plate 42 is swung together so that the limiting rod 55 cannot be in the L-shaped slot 58, thereby releasing the limiting of the connecting plate 42. Under the action of the resisting spring 43, the connecting plate 42 moves with the movable plate 41 to the side away from the cross bar 32. When the movable plate 41 moves to the side away from the cross bar 32, the hook-shaped teeth 44 can be resisted by the inner side of the square hole 6, so that the hook-shaped teeth 44 can be rotated at the position hinged with the movable plate 41 and stuck into the surface of the tree, thereby improving the overall fixing effect and avoiding slipping during fixing.

[0029] When the two sets of movable plates 41 and the connecting plate 42 move to the side away from the cross bar 32, the two sets of connecting plates 42 pull the hinged rods 45 so that the two sets of hinged rods 45 are perpendicular to the connecting plates 42. At this time, the hinged rods 45 push the contact rods 412 to move to the side away from the auxiliary ring 31, and the contact rods 412 push the limiting tooth plate 415 through the support rod 414 to contact the locking teeth 416 on the slider 47, and the locking teeth 416 are locked into the limiting tooth plate 415 to limit the slider 47, thereby limiting the cross bar 32, so that the cross bar 32 cannot continue to move, so that the cross bar 32 and the auxiliary ring 31 can stably contact the surface of the tree, further improving the fixing effect and avoiding loosening due to shaking.

[0030] At this time, it is only necessary to install the support rod 11, ball head 12, connecting column 13, sling 14 and wood transport rope 15 according to the comparative document, and then the tree can be cut. It is worth noting that this part of the principle is not the main innovative part of this application. This application mainly innovates the overall installation part of the device in the comparative document. The specific principle of the felling part has been fully disclosed in the comparative document and belongs to the existing public technology. Therefore, it is not elaborated on in this application.

[0031] After sawing, it is only necessary to unscrew the locking bolts 23 fixing the two sets of fixing rings 21 and remove the fixing rings 21. At this time, the auxiliary ring 31 is no longer interfered with. Under the action of the reset spring 33, the cross bar 32 brings the auxiliary ring 31 back to its original position. During this process, the cross bar 32 also drives the slider 47 and the connecting block 51 to move together.

[0032] The movable plate 41 and the connecting plate 42 are manually pushed to reset, and the connecting plate 42 controls the hinged rod 45 to reset, so that the hinged rod 45 no longer conflicts with the abutting rod 412, and the abutting rod 412 is reset under the action of the spring 413, and the abutting rod 412 pulls the limiting tooth plate 415 to reset through the support rod 414, so that the limiting tooth plate 415 is no longer engaged with the locking tooth 416, thereby releasing the limit on the slider 47, and under the action of the connecting spring 48, the slider 47 is completely reset.

[0033] During the resetting process of the connecting plate 42, the connecting plate 42 contacts the limit rod 55, and the connecting plate 42 resists the limit rod 55, so that the limit rod 55 swings toward the side close to the cross bar 32 at the position hinged with the vertical rod 52. When the limit rod 55 and the vertical rod 52 are inserted into the L-shaped slot 58, under the action of the torsion spring 57, the limit rod 55 swings and resets, thereby being stuck in the L-shaped slot 58 to limit the connecting plate 42 again, completing the overall resetting of the device. It is easy to use and does not require any skill to operate.

[0034] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
