Detailed Implementation
[0038] Hereinafter, exemplary embodiments according to this application will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this application, and not all embodiments of this application. It should be understood that this application is not limited to the exemplary embodiments described herein.
[0039] Figure 1 This is a schematic diagram of the structure of the fixing device and the target object 200 provided for an exemplary embodiment of this application. Figure 2 This is a schematic diagram of the fixing device provided for an exemplary embodiment of this application. Figure 1 and Figure 2As shown, the fixing device 100 provided in this embodiment may include a bracket 110 and a pressing member 120, with an installation space 130 formed between the pressing member 120 and the bracket 110. In practical applications, the installation space 130 can be used to assemble the target object 200.
[0040] In one embodiment, the target object 200 may include a pipe, cable, etc.
[0041] It should be noted that the size of the installation space 130 can be adjusted by adjusting the distance between the bracket 110 and the pressing member 120.
[0042] like Figure 1 and Figure 2 As shown, the fixing device 100 may further include a connector 140, which connects the pressing member 120 and the bracket 110. In practical applications, the target object 200 is placed within the installation space 130, and the connector 140 connects the pressing member 120 and the bracket 110. The connector 140 can apply a preload to the pressing member 120, which, under the preload, presses against the target object 200. The pressing member 120 and the bracket 110 jointly apply a pressing force to the target object 200. Thus, with the pressing member 120 and the bracket 110 jointly pressing against the target object 200, the target object 200 can be confined within the installation space 130; that is, the pressing member 120 and the bracket 110 can fix the target object 200 under the preload.
[0043] In one embodiment, the connection method between the connector 140 and the pressing member 120 may include abutment, threaded fit, interference fit, snap-fit, etc.
[0044] In one embodiment, the connection method between the connector 140 and the bracket 110 may include abutment, threaded fit, interference fit, snap-fit, etc.
[0045] It should be understood that the fixing device 100 provided in this application embodiment connects the pressing member 120 and the bracket 110 through the connector 140, which can restrict the target object 200 within the installation space 130. Compared with the fixing structure in the related technology that requires the disassembly and assembly of multiple bolts, this application embodiment only requires the disassembly and assembly of one part, the connector 140, to achieve the effect of fixing or loosening the target object 200. The disassembly and assembly process is simpler and more convenient, which helps to improve the disassembly and assembly efficiency.
[0046] like Figure 2 As shown, the installation space 130 may include a first subspace 131 and a second subspace 132. It should be understood that the first subspace 131 and the second subspace 132 can be used to assemble different target objects 200 respectively, which can effectively increase the assembly capacity.
[0047] like Figure 2 As shown, the first subspace 131 and the second subspace 132 are located on opposite sides of the connector 140. On the one hand, the connector 140 can prevent the target object 200 in the first subspace 131 and the target object 200 in the second subspace 132 from contacting each other and interfering with each other; on the other hand, the connector 140 can also play a limiting role, preventing the target object 200 in the first subspace 131 from moving into the second subspace 132, and preventing the target object 200 in the second subspace 132 from moving into the first subspace 131.
[0048] like Figure 2 As shown, the pressing member 120 may include a first pressing plate 121 and a second pressing plate 122. The first pressing plate 121 and the bracket 110 may form the aforementioned first subspace 131. The first pressing plate 121 may be used to press the target object 200 in the first subspace 131. The second pressing plate 122 and the bracket 110 may form the aforementioned second subspace 132. The second pressing plate 122 may be used to press the target object 200 in the second subspace 132.
[0049] like Figure 2 As shown, the pressing member 120 may also include a transition plate 123, which is disposed between the first pressing plate 121 and the second pressing plate 122. The opposite sides of the transition plate 123 are respectively connected to the first pressing plate 121 and the second pressing plate 122, and the connecting member 140 is connected to the transition plate 123.
[0050] It should be understood that, since the transition plate 123 connects the first pressure plate 121 and the second pressure plate 122, the connector 140, by connecting the transition plate 123, can apply a preload to both the first pressure plate 121 and the second pressure plate 122. Thus, using only one connector 140, the target object 200 in the first subspace 131 and the target object 200 in the second subspace 132 can be fixed, further improving the fixing efficiency.
[0051] In one embodiment, the transition plate 123, the first pressure plate 121 and the second pressure plate 122 can be connected to each other by processes such as welding or integral molding.
[0052] In one embodiment, the transition plate 123, the first pressure plate 121, and the second pressure plate 122 can be detachably connected by bolts, clips, or other structures. In another embodiment, the transition plate 123, the first pressure plate 121, and the second pressure plate 122 can be an integrated structure or separate structures.
[0053] It should be noted that, considering that the fixing device 100 is mainly used to fix the target object 200 of the tubular structure, therefore, if Figure 2As shown, the first pressure plate 121 is an arc-shaped plate, and the concave surface of the first pressure plate 121 faces the first subspace 131. In this way, the concave surface of the first pressure plate 121 can be adapted to the outer wall of the tubular target object 200. The concave surface of the first pressure plate 121 can play a certain role in covering the target object 200, which can prevent the target object 200 from leaving the first subspace 131, thereby enhancing the fixing effect of the first pressure plate 121 on the target object 200.
[0054] In one embodiment, when the first pressure plate 121 is an arc-shaped plate, the opening size and curvature of the first pressure plate 121 are adapted to the diameter of the target object 200 of the tubular structure. If the diameter of the target object 200 of the tubular structure changes, that is, the first pressure plate 121 with a different opening size and curvature needs to be replaced.
[0055] In one embodiment, when the first pressure plate 121 is a flat plate, when the diameter of the tubular target object 200 changes, the size of the first subspace 131 can be adjusted by adjusting the relative position between the first pressure plate 121 and the support 110, so that the adjusted first subspace 131 can accommodate the target object 200 with a changed diameter. In other words, the first pressure plate 121 does not need to be replaced to accommodate a target object 200 with a different diameter.
[0056] Similarly, such as Figure 2 As shown, the second pressure plate 122 is an arc-shaped plate, and the concave surface of the second pressure plate 122 faces the second subspace 132. In this way, the concave surface of the second pressure plate 122 can be adapted to the outer wall of the tubular target object 200. The concave surface of the second pressure plate 122 can play a certain role in covering the target object 200, which can prevent the target object 200 from leaving the second subspace 132, thereby enhancing the fixing effect of the second pressure plate 122 on the target object 200.
[0057] In one embodiment, when the second pressure plate 122 is an arc-shaped plate, the opening size and curvature of the second pressure plate 122 are adapted to the diameter of the target object 200 of the tubular structure. If the diameter of the target object 200 of the tubular structure changes, that is, it is necessary to replace the second pressure plate 122 with a different opening size and curvature.
[0058] In one embodiment, when the second pressure plate 122 is a flat plate, when the diameter of the tubular target object 200 changes, the size of the second subspace 132 can be adjusted by adjusting the relative position between the second pressure plate 122 and the bracket 110, so that the adjusted second subspace 132 can adapt to the target object 200 with a changed diameter. That is, the second pressure plate 122 does not need to be replaced to achieve adaptation for a target object 200 with a different diameter. In one embodiment, in order to facilitate the assembly of the transition plate 123 and the connector 140, and to facilitate the connector 140 to apply a stable preload to the transition plate 123, the transition plate 123 is selected as a flat plate structure. This increases the contact area between the connector 140 and the transition plate 123, improving the pressure stability.
[0059] like Figure 2 As shown, the transition plate 123 is provided with an assembly hole 124. The connector 140 includes a connecting portion 141 and a pre-compression portion 142. The connecting portion 141 passes through the assembly hole 124 and connects to the bracket 110. The pre-compression portion 142 is connected to the connecting portion 141 and is located on the side of the transition plate 123 away from the bracket 110. After the connecting portion 141 is connected to the bracket 110, the pre-compression portion 142 presses against the side of the transition plate 123 away from the bracket 110 to apply a preload to the transition plate 123.
[0060] In one embodiment, the outer diameter of the pre-pressing part 142 is larger than the diameter of the assembly hole 124. After the connecting part 141 passes through the assembly hole 124, the pre-pressing part 142 is outside the assembly hole 124, which facilitates the pre-pressing part 142 pressing against the transition plate 123.
[0061] In one embodiment, the connector 140 is a bolt, the bolt shank can be considered as the connecting part 141, and the bolt cap can be considered as the preload part 142.
[0062] like Figure 1 and Figure 2 As shown, the fixing device 100 may also include an elastic spacer 150, which is disposed in the installation space 130, and the opposite sides of the elastic spacer 150 abut against the pressing member 120 and the bracket 110 respectively.
[0063] In practical applications, the target object 200 can be fitted inside the elastic sleeve 150. On one hand, the elastic sleeve 150 serves as a vibration damping and buffering mechanism. That is, the elastic sleeve 150 prevents direct contact between the target object 200 and the pressing member 120, reducing damage to the target object 200 from the pressing member 120. Simultaneously, when the fixing device 100 vibrates, the elastic sleeve 150 can utilize its elastic buffering effect to reduce the vibration intensity transmitted to the target object 200, thus protecting the target object 200. On the other hand, because the elastic sleeve 150 has a certain elastic deformation space, it can compensate for manufacturing errors of the target object 200 and assembly errors of the target object 200 within the installation space 130, effectively enhancing adaptability.
[0064] In one embodiment, the elastic spacer 150 has an axially oriented notch that extends through both ends of the elastic spacer 150. It should be understood that the notch can further increase the deformability of the elastic spacer 150, thereby compensating for larger manufacturing errors of the target object 200 and larger assembly errors of the target object 200 within the installation space 130.
[0065] like Figure 1 and Figure 2 As shown, the fixing device 100 may further include a support cylinder 160, which is disposed between the pressing member 120 and the bracket 110. The opposite ends of the support cylinder 160 abut against the pressing member 120 and the bracket 110, respectively. In this way, the support cylinder 160 can support the pressing member 120. After the connecting member 140 applies a pre-tightening force to the pressing member 120, the support cylinder 160 can prevent local deformation of the pressed part of the pressing member 120, thereby avoiding the situation where the fixing effect is affected by the local deformation of the pressing member 120.
[0066] like Figure 2 As shown, a portion of the connector 140 passes through the pressing member 120 and the support cylinder 160, thereby connecting to the bracket 110. In this way, on the one hand, the support cylinder 160 acts as a guide during the passage of the connector 140, preventing the connector 140 from deviating from the preset installation direction and improving assembly accuracy; on the other hand, after the connector 140 is connected to the bracket 110, the support cylinder 160 can limit the connection of the connector 140, reducing the possibility of local bending of the connector 140.
[0067] In one embodiment, the support cylinder 160 is disposed between the transition plate 123 and the bracket 110, and the two ends of the support cylinder 160 abut against the transition plate 123 and the bracket 110 respectively.
[0068] Figure 3 A schematic diagram of the fixing device provided for another exemplary embodiment of this application. (See diagram below.) Figure 3As shown, in one embodiment, the support cylinder 160 may not be provided between the pressing member 120 and the bracket 110. After the connecting member 140 passes through the pressing member 120, it can be directly connected to the bracket 110. In this way, the connecting member 140 can also apply a pre-tightening force to the pressing member 120.
[0069] like Figure 3 As shown, the bracket 110 includes a support surface 111 for supporting the target object 200. The support surface 111 and the pressing member 120 are distributed vertically at intervals, and the pressing member 120 is located above the support surface 111.
[0070] Figure 4 A schematic diagram of the fixing device provided for another exemplary embodiment of this application. (See diagram below.) Figure 4 As shown, the bracket 110 includes a support surface 111 for supporting the target object 200. The support surface 111 and the pressing member 120 are distributed at intervals in the vertical direction, and the support surface 111 is located above the pressing member 120.
[0071] Figure 5 A schematic diagram of the fixing device provided for another exemplary embodiment of this application. (See diagram below.) Figure 5 As shown, the bracket 110 includes a support surface 111, which is used to support the target object 200. The support surface 111 and the pressing member 120 are distributed at intervals in the horizontal direction.
[0072] It should be noted that the terms "vertical direction," "horizontal direction," and "above" used in this application embodiment to indicate direction are all based on the fixed device 100 in its normal placement state. Specifically, the aforementioned vertical direction can be referred to as... Figures 3 to 5 The Y-axis direction and the horizontal direction can be referenced. Figures 3 to 5 The Z-axis direction in the equation.
[0073] Combination Figures 3 to 5 It should be understood that in practical applications, the position of the pressing member 120 can be adjusted according to the position of the support surface 111 of the bracket 110. Whether the support surface 111 and the pressing member 120 are distributed vertically or horizontally, the pressing member 120 and the support surface 111, under the action of pre-tightening force, can confine the target object 200 within the installation space 130. That is, the fixing device 100 provided in this embodiment can adjust the relative positional relationship between the pressing member 120 and the support surface 111 according to the actual assembly environment of the target object 200, to adapt to different assembly environments and possesses good versatility.

[0077] In one embodiment, the construction machinery may include excavators, loaders, cranes, etc.
