Description

Technical Field

[0001] This invention relates to the field of garden equipment technology, specifically to a tree fixing frame for landscape gardens. Background Technology

[0002] In forestry, new trees need to be planted every year. After transplanting, trees need to be reinforced with appropriate support frames to ensure their wind resistance and resistance to falling. The conventional method is to distribute multiple support frames on the outside of the transplanted tree, and then fix the tops of the support frames to the outside of the tree with wire or other means. This achieves the support and protection of the transplanted tree.

[0003] According to a Chinese patent application publication number 202411330002.7, a tree transplant support and protection device for forestry is disclosed. Through the cooperation of a protective pad, an arc-shaped cavity, a driving component, and a fastening nut, the air pressure inside the protective pad changes with the growth of the tree. This air pressure then powers the driving component to move the fastening nut, thereby adjusting the space between the two fixing rings and protecting the tree. However, as the tree grows, it inevitably carries the fixing rings upwards, requiring manual periodic adjustment of the support rod's length. In other words, the aforementioned tree transplant support and protection device for forestry is not ideal in terms of adaptability to tree growth and cannot adjust itself automatically according to tree growth. Therefore, we propose a tree fixing frame for landscape gardens to solve the above-mentioned technical problems. Summary of the Invention

[0044] Linear guide rails are symmetrically distributed and fixedly installed on top of the base about its central axis;

[0045] A linear slider is slidably mounted on the periphery of a linear guide rail, and the top of the linear slider is fixedly connected to the bottom of the walkway.

[0046] As a preferred embodiment of the present invention, a guardrail is fixedly provided around the perimeter of the plurality of fixed units, and the guardrail is used for the enclosure and protection of the tree fixing frame in the landscape garden.

[0047] Compared with the prior art, the beneficial effects of the present invention are:

[0048] 1. In this invention, by fixing the ring hoop at an appropriate height on the tree trunk and fixing the ends of multiple steel cables to the surface of the ring hoop with a locking buckle, the vertical shaft and the I-beam wheel cannot rotate due to the torsion limiting unit's torsion limiting effect on the vertical shaft. Therefore, the tension of the three steel cables on the tree trunk in multiple directions cancels each other out, thereby laterally straightening the tree and preventing it from falling to the side.

[0049] 2. In this invention, when the wind blows and the tree trunk sways to one side, one of the steel cables corresponding to the wind direction is pulled, causing the steel cable to exert a pulling force on the winding wheel. This pulling force can be decomposed into a component force towards the tree and an upward component force. At this time, because the angle R1 is large, the upward component force of the steel cable is small and insufficient to pull the winding wheel upward. At this time, the pulling force of the steel cable is used to counteract the swaying force of the tree, ensuring that the tree will not fall to the side.

[0050] 3. In this invention, as the tree grows taller, it causes the annular hoop to move upward, resulting in a gradual decrease in the angles of R1 and R2. At this time, the steel cable is stretched. Because the angle of R1 decreases, the upward component of the tension force on the winding wheel increases, causing the winding wheel to move upward. This releases the torsion limiting unit from limiting the torsion of the vertical shaft and the I-beam. The steel cable is stretched, and through the winding action of the winding wheel and the two winding wheels, the I-beam rotates, releasing the remaining steel cable portion wound inside the I-beam, thereby eliminating the stretching of the steel cable.

[0051] 4. In this invention, after the tension force on the steel cable disappears, the spring's rebound force is released, pushing the spring bracket, guide rod, bearing seat 1, and winding wheel 1 to return to their original positions. Furthermore, the spring bracket also drives the metal cantilever plate to return to its original positions, and further drives the torque limiting disc 1 to move downwards through the metal cantilever plate, re-inserting it into the cavity. At the same time, due to the setting of guide ramp 2 and guide ramp 1, a guiding effect can be achieved, allowing the keyway to slide smoothly and lock onto the outer periphery of the key teeth. At this time, the torque limiting disc 1 limits the torque of the torque limiting disc 2, causing the vertical shaft and the I-beam wheel to be torque-limited, and the steel cable inside the I-beam wheel is interrupted and released, ensuring that the steel cable does not accumulate between the trunk and the winding wheel 1, so that the steel cable has sufficient tension.

[0052] 5. In this invention, the rotation of the I-beam wheel drives the vertical shaft and gear to rotate. Since the gear meshes with the rack, the rotation of the gear causes it to roll along the side of the rack, thereby driving the walkway to translate along the sliding trajectory of the linear guide rail and the linear slider. This causes the angles R1 and R2 to gradually increase. The increase in the angle of R1 reduces the upward component of the force exerted by the cable on the winding wheel, so when the tree sways, the winding wheel will not move upward. Therefore, under the meshing action of the keyway and the key teeth, the I-beam wheel cannot rotate. Thus, the length of the cable between the winding wheel and the tree will not change, thereby providing a lateral straightening effect on the tree. The increase in the angle of R2 increases the horizontal component of the force exerted by the cable on the tree, resulting in a better lateral tension effect on the tree, that is, a better lateral fixation effect on the tree.

Detailed Implementation

[0065] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0066] Please see Figures 1 to 11 The technical solution provided by the present invention specifically includes the following embodiments:

[0067] A tree fixing frame for landscape gardens includes a fixing unit 100, a winding unit 200, a torsion limiting unit 300, a walking unit 400, and a guardrail 500. The fixing units 100 are arranged in a circumferential array around the tree for fixing the tree. The winding unit 200 is fixedly installed on the top of the fixing unit 100. The torsion limiting unit 300 is fixedly installed on the surface of the winding unit 200 for braking the fixing unit 100. The walking unit 400 is fixedly installed on the top of the fixing unit 100 for moving the fixing unit 100. The guardrail 500 is fixedly installed around the perimeter of the multiple fixing units 100 for enclosure and protection of the tree fixing frame for landscape gardens.

[0068] For further details, please refer to [link / reference]. Figures 4-7 As shown:

[0069] The fixing unit 100 includes a base 101, a walking platform 102, a vertical shaft 103, an I-beam wheel 104, a steel cable 105, and an annular hoop 106. The base 101 is fixedly installed on the ground around the tree via a channel steel beam. The walking platform 102 is movably mounted on the top of the base 101. A groove 1002 is provided at the end of the walking platform 102 closest to the tree. The vertical shaft 103 is rotatably mounted inside the walking platform 102 via a bearing and passes through the top and bottom of the walking platform 102. The I-beam wheel 104 is fixedly installed on the outer wall of the vertical shaft 103 and is located at the top of the walking platform 102. A gap for installing a torque limiting unit 300 is provided between the bottom of the I-beam wheel 104 and the top of the walking platform 102. The steel cable 105 is wound around the inside of the I-beam wheel 104. The annular hoop 106 is fixedly installed on the outer periphery of the tree trunk. The end of the steel cable 105 away from the I-beam wheel 104 is fixedly connected to the annular hoop 106 via a buckle.

[0070] Specifically, at least three or more bases 101 are fixedly installed on the outer perimeter of the tree trunk using channel steel beams, with equal angles between each base 101. The channel steel beams are fixed to the ground using ground nails (but not limited to ground nails). A ring hoop 106 is fixedly installed on the tree trunk at an appropriate height, and the ends of multiple steel cables 105 are fixedly connected to the surface of the ring hoop 106 using locking buckles (as shown in the attached diagram). Figure 1 As shown, due to the torsion limiting effect of the torsion limiting unit 300 on the vertical shaft 103, the vertical shaft 103 and the I-beam wheel 104 cannot rotate. Therefore, the tension of the three steel cables 105 on the tree trunk in multiple directions cancels each other out, thereby straightening the tree laterally and preventing it from falling over.

[0071] For further details, please refer to [link / reference]. Figures 5-8 As shown:

[0072] The winding unit 200 includes support rods 201, support platform 202, linear bearings 203, guide rods 204, bearing housing 205, winding wheel 206, spring bracket 207, spring 208, bearing housing 209, and winding wheel 2010. Four support rods 201 are fixedly installed on the front and rear ends of the top of the walkway 102, distributed horizontally. The support platform 202 is fixedly installed on the top of the four support rods 201. Four linear bearings 203 are symmetrically fixed to the left and right ends of the top of the support platform 202 along its central axis, and the guide rods 204 are slidably installed inside the four linear bearings 203. Two bearing housings 205 are fixedly installed on the tops of the two front guide rods 204 and the two rear guide rods 204, respectively. 6. Rotatably installed between the front and rear bearing seats 205, the steel cable 105 is wound around the surface of the winding wheel 206. The spring bracket 207 is fixedly installed at the bottom of the two guide rods 204 at the front end and the bottom of the two guide rods 204 at the rear end. There are two spring brackets 207 in total. The springs 208 are respectively sleeved on the periphery of the four guide rods 204 and fixedly installed between the bottom of the support platform 202 and the top of the spring bracket 207. The bearing seats 209 are fixedly installed on the two opposite surfaces of the groove 1002. The winding wheel 2010 is rotatably installed between the two bearing seats 209. The steel cable 105 is wound from the bottom of the lower winding wheel 2010, passes through the space between the upper and lower winding wheels 2010, and is fixedly connected to the annular hoop 106 after being wound from the lower end of the winding wheel 206.

[0073] Specifically, the ring hoop 106 is fixedly installed at an appropriate height on the tree trunk, and the ends of multiple steel cables 105 are fixedly connected to the surface of the ring hoop 106 by a locking buckle. At this time, the angle between the steel cable 105 and the vertical plane of the winding reel 206 is R1, and the angle between the steel cable 105 and the tree trunk is R2 (as shown in the attached figure). Figure 11 As shown, when the wind blows and the tree trunk sways to one side, one of the steel cables 105 corresponding to the wind direction is pulled, causing the steel cable 105 to exert a pulling force on the winding wheel 206. This pulling force can be decomposed into a component force towards the tree and an upward component force. At this time, because the angle R1 is large, the upward component force of the steel cable 105 is small and insufficient to pull the winding wheel 206 upward. At this time, the pulling force of the steel cable 105 is used to counteract the swaying force of the tree, ensuring that the tree will not fall to the side.

[0074] For further details, please refer to [link / reference]. Figure 8 , Figure 9 As shown:

[0075] The torsion limiting unit 300 includes a metal cantilever plate 301, a circular slot 302, a first torsion limiting disc 303, a second torsion limiting disc 304, a keyway 305, a first guide slope 306, a circular cavity 307, key teeth 308, and a second guide slope 309. The metal cantilever plate 301 is fixedly installed at the bottom of the two spring brackets 207 away from the tree and located at the bottom of the I-beam wheel 104. The circular slot 302 is opened at the top of the metal cantilever plate 301 away from the spring bracket 207. The first torsion limiting disc 303 is fixedly installed at the bottom of the metal cantilever plate 301 and located outside the opening of the circular slot 302. The second torsion limiting disc 304 is fixedly installed on the outer wall of the vertical shaft 103. A fitting gap is provided between the outer wall of the first disc 303 and the inner wall of the second torsion limiting disc 304, and the fitting gap between the outer wall of the first torsion limiting disc 303 and the second torsion limiting disc 304 is about 1±0.5mm. Keyways 305 are evenly distributed at the lower part of the outer wall of the first torsion limiting disc 303. Guide slope 1 306 is provided at both ends of the bottom of the inner wall of the keyway 305. Cavity 307 is provided at the top of the second torsion limiting disc 304. Key teeth 308 are integrally formed and fixed on the inner wall of the cavity 307 and are distributed in a circumferential array. The number and specifications of key teeth 308 are adapted to the number and specifications of keyways 305. Guide slope 2 309 is provided at both ends of the top of key teeth 308.

[0076] Specifically, as the tree grows taller, it causes the annular hoop 106 to move upwards, resulting in a gradual decrease in the angles R1 and R2. At this time, the steel cable 105 is stretched. Due to the decrease in the angle R1, the upward component of the tension force on the winding wheel 206 increases, causing the winding wheel 206 to move upwards. This upward movement of the winding wheel 206, through the bearing seat 205, drives the guide rod 204 to slide upwards along the inside of the linear bearing 203. Simultaneously, the guide rod 204 also... The upward movement of the spring bracket 207 and the metal cantilever plate 301 causes the spring 208 to compress and store force. The upward movement of the metal cantilever plate 301 also causes the first torsion limiting disc 303 to move upward, resulting in the separation of the first torsion limiting disc 303 from the second torsion limiting disc 304. This disengages the multiple keyways 305 from the engagement of the multiple springs 208. At this point, due to the tension on the steel cable 105, the winding action of the first winding wheel 206 and the two upper and lower winding wheels 2010 drives the I-beam wheel 104 to rotate, releasing the winding force. The remaining portion of the steel cable 105 inside the H-beam reel 104 is connected, thereby eliminating the tension on the steel cable 105. Once the tension on the steel cable 105 disappears, the restoring force of the spring 208 is released, pushing the spring bracket 207, guide rod 204, bearing seat 205, and winding reel 206 downwards to reset. Furthermore, the spring bracket 207 also drives the metal cantilever plate 301 downwards to reset, further driving the torsion limiting disc 303 downwards via the metal cantilever plate 301, allowing it to re-insert into the cavity 307. Meanwhile, the guide ramp 309 and guide ramp 306 provide a guiding effect, allowing the keyway 305 to slide smoothly around the key tooth 308. At this time, the torque limiting disk 303 limits the torque of the torque limiting disk 304, causing the vertical shaft 103 and the I-beam wheel 104 to be torque-limited. The steel cable 105 inside the I-beam wheel 104 is then interrupted and released, ensuring that the steel cable 105 does not accumulate between the trunk and the winding wheel 206, so that the steel cable 105 has sufficient tension.

[0077] For further details, please refer to [link / reference]. Figure 5 As shown:

[0078] The traveling unit 400 includes a gear 401, a rack 402, a linear guide rail 403, and a linear slider 404. The gear 401 is fixedly installed on the lower part of the outer wall of the vertical shaft 103. The rack 402 is fixedly installed on the top of the base 101 and meshes with the gear 401. The linear guide rail 403 is symmetrically distributed about the central axis of the base 101 and fixedly installed on its top. The linear slider 404 is slidably installed on the periphery of the linear guide rail 403 and the top of the linear slider 404 is fixedly connected to the bottom of the traveling table 102.

[0079] Specifically, the rotation of the I-beam wheel 104 drives the vertical shaft 103 and gear 401 to rotate. Since gear 401 meshes with rack 402, the rotation of gear 401 causes it to roll along the side of rack 402, thereby driving the walkway 102 to translate along the sliding trajectory of linear guide 403 and linear slider 404. This causes the angles R1 and R2 to gradually increase. The increase in the angle R1 reduces the upward component of the force exerted by the steel cable 105 on the winding wheel 206. Therefore, when the tree sways, the winding wheel 206 will not move upward. Thus, under the meshing action of keyway 305 and key tooth 308, the I-beam wheel 104 cannot rotate. Therefore, the length of the steel cable 105 between the winding wheel 206 and the tree will not change, thus providing a lateral straightening effect on the tree. The increase in the angle R2 causes the horizontal component of the force exerted by the steel cable 105 on the tree to increase, thus providing a better lateral tension effect on the tree. In other words, the lateral fixation effect on the tree is better.

[0080] This solution provides a tree fixing frame for landscape gardens. During operation, at least three bases 101 are fixedly installed on the outer perimeter of the tree trunk via channel steel beams, with equal angles between each base 101. The channel steel beams are fixed to the ground using ground nails (but not limited to ground nails). A ring hoop 106 is fixedly installed on the tree trunk at an appropriate height, and the ends of multiple steel cables 105 are fixedly connected to the surface of the ring hoop 106 via locking buckles (as shown in the attached diagram). Figure 1 As shown in the attached diagram, at this time, the angle between the steel cable 105 and the vertical plane of the winding reel 206 is R1, and the angle between the steel cable 105 and the tree trunk is R2 (as shown in the attached diagram). Figure 11 As shown, due to the snapping action of the keyway 305 and the key tooth 308, the vertical shaft 103 and the I-beam wheel 104 cannot rotate. Therefore, the tension of the three steel cables 105 on the tree trunk in multiple directions cancels each other out, thereby straightening the tree laterally and preventing it from falling over.

[0081] When the wind blows and the tree trunk sways to one side, one of the steel cables 105 corresponding to the wind direction experiences a pulling force, causing the steel cable 105 to exert a pulling force on the winding reel 206. This pulling force can be decomposed into a component towards the tree and an upward component. At this time, because the angle R1 is relatively large, the upward component of the pulling force of the steel cable 105 is small and insufficient to pull the winding reel 206 upward. At this point, the pulling force of the steel cable 105 counteracts the swaying force of the tree, ensuring that the tree does not fall to the side. However, as the tree grows taller, it will cause the ring hoop 106 to move upward, causing the angles of R1 and R2 to gradually... As the angle R1 decreases, the steel cable 105 is stretched. Because the angle R1 decreases, the upward component of the tension force on the winding wheel 206 increases, causing the winding wheel 206 to move upwards. This upward movement of the winding wheel 206, through the bearing seat 205, drives the guide rod 204 to slide upwards along the interior of the linear bearing 203. Simultaneously, the guide rod 204 also drives the spring bracket 207 and the metal cantilever plate 301 to move upwards, causing the spring 208 to compress and store energy. The upward movement of the metal cantilever plate 301 then drives the torsion limiting disc 303 to move upwards as well, causing the torsion limiting disc 303 and the torsion limiting disc 302 to move upwards together. 4. Separation: Multiple keyways 305 disengage from multiple springs 208. At this time, due to the tension on the steel cable 105, the winding action of the first winding wheel 206 and the two second winding wheels 2010 drives the I-beam 104 to rotate, releasing the remaining portion of the steel cable 105 wound inside the I-beam 104, thereby eliminating the tension on the steel cable 105. When the tension on the steel cable 105 disappears, the rebound force of the springs 208 is released, pushing the spring bracket 207, guide rod 204, bearing seat 205, and winding wheel 206 to return to their original position downwards. Furthermore, the spring bracket 207 also drives the metal cantilever plate 301 downwards. The device is reset and then moves downward via the metal pick plate 301 to drive the torque limiting disc 303 to re-insert into the cavity 307. At the same time, the guide slope 309 and guide slope 306 provide a guiding effect, allowing the keyway 305 to slide smoothly around the key teeth 308. At this time, the torque limiting disc 303 limits the torque of the torque limiting disc 304, causing the vertical shaft 103 and the I-beam wheel 104 to be torque-limited. The steel cable 105 inside the I-beam wheel 104 is then interrupted and released, ensuring that the steel cable 105 does not accumulate between the trunk and the winding wheel 206, so that the steel cable 105 has sufficient tension.

[0082] Meanwhile, the rotation of the I-beam wheel 104 drives the vertical shaft 103 and gear 401 to rotate. Since gear 401 meshes with rack 402, the rotation of gear 401 causes it to roll along the side of rack 402, thereby driving the walkway 102 to translate along the sliding trajectory of linear guide 403 and linear slider 404. This causes the angles R1 and R2 to gradually increase. The increase in the angle R1 reduces the upward component force of the steel cable 105 on the winding wheel 206. Therefore, when the tree sways, the winding wheel 206 will not move upward. Thus, under the meshing action of keyway 305 and key tooth 308, the I-beam wheel 104 cannot rotate. Therefore, the length of the steel cable 105 between the winding wheel 206 and the tree will not change, thus providing a lateral straightening effect on the tree. The increase in the angle R2 causes the horizontal component force of the steel cable 105 on the tree to increase, thus providing a better lateral tension effect on the tree. In other words, the lateral fixation effect on the tree is better.

[0083] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention.
