Description

Technical Field

[0001] The utility model relates to the technical field of tree maintenance, in particular to an arbor fixing and supporting device. Background Art

[0002] With the development of urban modernization, gardening and greening plays a very important role in urban construction. It has the functions of reducing dust in the air, reducing noise, and mitigating the urban heat island effect. It plays an important role in maintaining the ecological balance of the city and promoting sustainable urban development. In the process of gardening and greening, trees have large crowns. After transplantation, they can show the greening effect in the shortest time and quickly improve the urban landscape effect. Therefore, large-scale tree transplantation is widely used in gardening and greening.

[0003] After the tree is transplanted, because the tree has a large crown, the new root system has not grown and expanded, and has no fixation ability, it is easy to tilt or even fall, which affects the root growth of the tree after transplantation and thus affects the survival rate. At the same time, there are also safety hazards. Therefore, tools are needed to support and fix the tree after planting.

[0004] At present, the common tree support and fixation devices include clamp fixing, plastic cup fixing, strap fixing, etc. However, the clamp and strap are usually tightly wrapped around the outer periphery of the tree, without deformation margin. During use, as the tree grows, the clamp and strap cannot be adaptively adjusted in size, which suppresses the normal growth of the tree. Utility Model Content

[0005] Based on the above situation, the main purpose of the utility model is to provide a tree fixing and supporting device to solve the problem that the clamps and straps are usually tightly wrapped around the periphery of the tree without any deformation margin, and during use, as the tree grows, the clamps and straps cannot be adaptively adjusted in size, thereby suppressing the normal growth of the tree.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A tree fixing and supporting device comprises an external fixing component and an internal limiting component;

[0008] The external fixing assembly includes two fixing rings, which can be fixed to each other and enclose a mounting area;

[0009] The internal limiting component includes two inflatable airbags, the two inflatable airbags are located in the installation area, the two inflatable airbags are respectively fixed to the two fixing rings, and limiting grooves are provided on the sides of the two inflatable airbags close to each other.

[0010] Preferably, mounting plates are fixed on both upper and lower sides of the inner surfaces of the two fixing rings, and a mounting groove with a U-shaped cross-section is formed on one side of the two mounting plates close to each other and the inner side of the fixing ring, and the inflatable airbag is adhesively fixed in the mounting groove.

[0011] Preferably, pressure sensors are fixed on the inner sides of the two mounting plates, and sensor probes of the pressure sensors are in contact with the inflatable airbags.

[0012] Preferably, the fixing ring and the inflatable airbag are both semicircular.

[0013] Preferably, a rubber pad is fixed in the limiting groove and is in direct contact with the trunk of the tree.

[0014] Preferably, an exhaust port is provided on the upper side of the inflatable airbag, and a closing cover is detachably connected to the upper side of the exhaust port.

[0015] Preferably, both ends of the two fixing rings are fixed with convex plates, the surfaces of the convex plates are provided with through holes, and the two convex plates on the same side are fixed by bolts and nuts.

[0016] The beneficial effects of the utility model are as follows: when the tree fixing and supporting device provided by the application is used, two fixing rings and the inflatable airbag that has completed the inflation work are placed on both sides of the tree trunk, and the two fixing rings are moved close to the tree trunk and fixed, so that the tree trunk can be placed in the limiting grooves of the two inflatable airbags, and the air pressure of the inflatable airbags can hold up the tree trunk and support the tree trunk. Since the inflatable airbag is usually made of soft material, and since the trunk is supported by air pressure, during the gradual growth of the tree, the inflatable airbag can have a certain amount of deformation margin, can adaptively adjust a certain size, and can reduce the pressure on the growth of the tree trunk. The trunk of a tree does not grow vertically during its growth process, and will tilt a little during its growth. Due to the supporting characteristics of the inflatable airbag, the supporting contact surface between the inflatable airbag and the trunk of the tree has a high degree of freedom, and its contact surface can change with the tilt angle of the trunk of the tree. When the tree tilts, the inflatable airbag can still contact the trunk of the tree over a large area, thereby improving the supporting stability of the tree by the fixed support device of the tree.

[0017] Other beneficial effects of the utility model will be explained through the introduction of specific technical features and technical solutions in the specific implementation manner. Through the introduction of these technical features and technical solutions, those skilled in the art should be able to understand the beneficial technical effects brought about by the technical features and technical solutions.

[0026] In the description of the present invention, it should be understood that the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. In addition, in the description of the present invention, unless otherwise specified, the meaning of "plurality" is two or more.

[0027] Reference Figure 1-3 The utility model provides a tree fixing and supporting device, including an external fixing component 1 and an internal limiting component 2. The external fixing component 1 is connected and fixed to the ground to play a basic supporting role. The internal limiting component 2 is fixed in the external fixing component 1 and contacts with the trunk of the tree, playing a direct limiting supporting role for the trunk of the tree.

[0028] The external fixing assembly 1 includes two fixing rings 11, which can be fixed to each other. When the two fixing rings 11 are fixed to each other, they enclose a mounting area 12, and the internal limit assembly 2 is fixed in the mounting area 12. The outer circumferences of the two fixing rings 11 are rotatably connected to a plurality of connecting rods 13, and the rotation axes of the connecting rods 13 are arranged horizontally so that the connecting rods 13 can rotate up and down. The lower end of each connecting rod 13 is fixedly connected to a fixing nail 131, which can be nailed into the ground to determine the basic position of the tree support device provided by the present application.

[0029] The internal limiting component 2 includes two inflatable airbags 21, and the two inflatable airbags 21 are located in the installation area 12. The two inflatable airbags 21 can be fixed to the two fixing rings 11 respectively. The two inflatable airbags 21 are provided with semicircular limiting grooves 22 on one side close to each other. When the inflatable airbags 21 are inflated, the two limiting grooves 22 are coaxially arranged, and the trunk of the tree can be placed in the two limiting grooves 22.

[0030] When the tree fixing and supporting device provided by the present application is in operation, the two fixing rings 11 and the inflatable airbag 21 that has completed the inflation work are placed on both sides of the tree trunk, and the two fixing rings 11 are moved close to the tree trunk and fixed, so that the tree trunk can be placed in the limiting grooves 22 of the two inflatable airbags 21, and the air pressure of the inflatable airbags 21 can hold up the tree trunk and support the tree trunk. Since the inflatable airbag 21 is usually made of soft material and uses gas pressure to support the tree trunk, during the gradual growth of the tree, the inflatable airbag 21 can have a certain amount of deformation margin, can adaptively adjust a certain size, and can reduce the pressure on the growth of the tree trunk. The trunk of the tree does not grow vertically during its growth process. It will tilt slightly during its growth process. Due to the supporting characteristics of the inflatable airbag 21, the supporting contact surface between the inflatable airbag 21 and the trunk of the tree has a high degree of freedom, and its contact surface can change with the angle of the inclination of the trunk of the tree, so that when the tree is tilted, the inflatable airbag 21 can still contact the trunk of the tree with a large area, thereby improving the supporting stability of the tree by the arbor fixing support device. It should be noted that the radial size of the limit groove 22 is not limited, and it needs to change according to the change in the diameter of the tree when the tree is transplanted; the initial air pressure of the tree fixed in the inflatable airbag 21 can be changed according to the diameter, height, and weight of the tree.

[0031] As an embodiment, the shapes of the fixing ring 11 and the inflatable airbag 21 are both semicircular. It should be noted that the shapes of the fixing ring 11 and the inflatable airbag 21 can also be square rings or other ring shapes, as long as the inside of the fixing ring 11 can fix the inflatable airbag 21, and the inside of the inflatable airbag 21 has a limiting groove 22 that can contact the trunk of the tree. It is just that the semicircular fixing ring 11 and the inflatable airbag 21 are regular in shape and save space.

[0032] As an embodiment, a rubber pad 221 is fixed to the inner side of the limiting groove 22 , and the rubber pad 221 can directly contact with the trunk of the tree to prevent the trunk of the tree from contacting the inflatable airbag 21 and causing the inflatable airbag 21 to be damaged and leak.

[0033] As an embodiment, an air discharge port 222 is opened on the upper side of the inflatable airbag 21, and a closing cover 223 is detachably connected to the air discharge port 222, so that the amount of gas in the inflatable airbag 21 can be flexibly adjusted, and the pressure of the inflatable airbag 21 on the trunk of the tree can be adjusted.

[0034] As an embodiment, both ends of the two fixing rings 11 are fixed with a protruding plate 14, the protruding plate 14 is provided with a through hole, and the two protruding plates 14 on the same side are penetrated by bolts, and nuts are fastened on the bolts, so that the two fixing rings 11 can be fixed, so that the tree fixing support device can be quickly disassembled and assembled.

[0035] Furthermore, mounting plates 15 are fixed to the upper and lower sides of the inner surfaces of the two fixing rings 11. The two mounting plates 15 are close to each other and the inner side of the fixing ring 11 to form a mounting groove 16 with a U-shaped cross section. The opening of the mounting groove 16 is set toward the trunk of the tree. The inflatable airbag 21 can be inserted into the mounting groove 16. In this embodiment, the mounting groove 16 is coated with adhesive so that the outer side of the inflatable airbag 21 can be bonded to the mounting groove 16. The inflatable airbag 21 can also be directly fixed inside the fixing ring 11, but the mounting plate 15 can make the inflatable airbag 21 more firmly fixed, with better fixation, and it can also facilitate the operation of the installer during installation.

[0036] Furthermore, pressure sensors 17 are fixed on the inner sides of the two mounting plates 15. The pressure sensors 17 are prior art and will not be described in detail in this application. The pressure sensors 17 can be fixed by bonding. The sensor probe of the pressure sensor 17 is in contact with the inflatable airbag 21. After the trunk of the tree is fixed, as the trunk of the tree continues to grow and its diameter increases, the pressure on the inflatable airbag 21 also increases. The pressure sensor 17 can obtain pressure parameters, and maintenance personnel can reduce the air pressure of the inflatable airbag 21 after detection, which is beneficial to the long-term maintenance of the later tree fixing support device. The pressure sensor 17 in this application enables the tree fixing device to cooperate with the existing signal transmitting device, and remotely send the pressure parameter signal to the control center, so that the staff can remotely monitor the working condition of the tree fixing device.

[0037] The implementation principle of the present application is as follows: when the tree fixing and supporting device provided by the present application is working, the two fixing rings 11 and the inflatable airbag 21 that has completed the inflation work are placed on both sides of the tree trunk, and the two fixing rings 11 are moved close to the tree trunk and fixed, so that the tree trunk can be placed in the limiting grooves 22 of the two inflatable airbags 21, and the air pressure of the inflatable airbags 21 can hold up the tree trunk and support the tree trunk. Since the inflatable airbag 21 is usually made of soft material, and since the trunk is supported by air pressure, during the gradual growth of the tree, the inflatable airbag 21 can have a certain amount of deformation margin, can adaptively adjust the size to a certain extent, and can reduce the pressure on the growth of the tree trunk. The trunk of the tree does not grow vertically during its growth process. It will tilt slightly during its growth process. Due to the supporting characteristics of the inflatable airbag 21, the supporting contact surface between the inflatable airbag 21 and the tree trunk has a high degree of freedom. The contact surface can change with the angle of the tree trunk. When the tree tilts, the inflatable airbag 21 can still contact the tree trunk with a large area, thereby improving the supporting stability of the tree fixed support device for the tree. During long-term use, technicians can adjust the air pressure of the inflatable airbag 21 by observing the pressure measurement parameters provided by the pressure sensor 17.

[0038] Those skilled in the art will appreciate that, without conflict, the above-mentioned preferred solutions can be freely combined and superimposed.

[0039] It should be understood that the above-mentioned embodiments are merely illustrative and not restrictive. Without departing from the basic principles of the present invention, various obvious or equivalent modifications or substitutions that can be made by technicians in this field to the above details will be included in the scope of the claims of the present invention.
