[0043] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0044] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0045] Please refer to Figure 1 and Figure 2 , Figure 1 A schematic diagram of the structure of the lifting and crossing frame 100 provided in this embodiment; Figure 2 A schematic diagram of the structure of the lifting mechanism 110 and the frame 140 provided in this embodiment.

[0046] The present invention provides a lifting spanning frame 100, which includes a lifting mechanism 110, a supporting mechanism 120, a protecting mechanism 130 and a frame body 140; the lifting mechanism 110, the supporting mechanism 120 and the protecting mechanism 130 are connected to each other, and the frame body 140 is connected to the lifting mechanism 110 and the protecting mechanism 130.

[0047] The lifting span frame 100 acts on the transmission line at high altitude, so it can be understood that the support mechanism 120 is located above the lifting mechanism 110, and the lifting mechanism 110 is used to drive the support mechanism 120 to move in a preset direction, that is, the vertical direction. The frame body 140 is set on the ground, and the lifting mechanism 110 is located above the support plate 141 that is in contact with the ground.

[0048] In this embodiment, the lifting mechanism 110 includes a first hydraulic cylinder 111 and a second hydraulic cylinder 112; the first hydraulic cylinder 111 includes a first piston 1111 and a first chamber body 1112; the first piston 1111 and the first chamber body 1112 are movably cooperated to change the volume of the first chamber body 1112; the second hydraulic cylinder 112 includes a second piston 1121 and a second chamber body 1122; the second piston 1121 and the second chamber body 1122 are movably cooperated to change the volume of the second chamber body 1122; wherein, the first chamber body 1112 is connected to the second chamber body 1122; when the volume of the first chamber body 1112 gradually decreases, the volume of the second chamber body 1122 gradually increases.

[0049] It should be noted that, because the first piston 1111 and the first chamber body 1112 are movably matched, the volume of the first chamber body 1112 can be changed by the movement of the first piston 1111. Similarly, the second piston 1121 and the second chamber body 1122 are movably matched, and the volume of the second chamber body 1122 can be changed by the movement of the second piston 1121.

[0050] In this embodiment, the first chamber body 1112 and the second chamber body 1122 are connected, and the first chamber body 1112 and the second chamber body 1122 are both closed chambers, so the total volume of the first chamber body 1112 and the second chamber body 1122 remains unchanged. When the first piston 1111 moves to compress the volume of the first chamber body 1112, part of the liquid in the first chamber body 1112 flows into the second chamber body 1122, and the liquid acts on the first piston 1111 to transmit the driving force to the second piston 1121, so that the second piston 1121 moves to increase the volume of the second chamber body 1122. It can be understood that the first chamber body 1112 and the second chamber body 1122 are both filled with liquid.

[0051] It should be noted that, in this embodiment, the liquid filled in the first chamber body 1112 and the second chamber body 1122 is mineral oil, and an insulation member 117 is also provided on the periphery of the first chamber body 1112 to insulate the mineral oil, thereby preventing the mineral oil from condensing or evaporating due to changes in ambient temperature.

[0052] Specifically, please refer to Figure 1 and Figure 2 In this embodiment, the movement directions of the first piston 1111 and the second piston 1121 are both preset directions, i.e., vertical directions. When the first piston 1111 moves downward, the volume of the first chamber body 1112 decreases, the volume of the second chamber body 1122 increases, and the second piston 1121 moves upward.

[0053] The lifting span frame 100 further includes a support mechanism 120, which is used to carry the transmission line; the support mechanism 120 is connected to the second piston 1121, and the second piston 1121 drives the support mechanism 120 to move in a preset direction. Therefore, when the first piston 1111 moves upward or downward in the vertical direction to change the volume of the first chamber body 1112, the second piston 1121 can drive the support mechanism 120 to move downward or upward in the vertical direction, thereby realizing the lifting and lowering of the support mechanism 120 and the transmission line.

[0054] The lifting span frame 100 further includes a protection mechanism 130, which is connected to the lifting mechanism 110 and the supporting mechanism 120 and is used to be inserted into the ground. Thus, the protection mechanism 130 is inserted into the ground, thereby preventing the lifting span frame 100 from tipping over, improving the stability of the lifting span frame 100, preventing the transmission line from falling from a high altitude, and improving the safety of the lifting span frame 100.

[0055] For further information, please refer to Figure 1 and Figure 2The lifting mechanism 110 also includes an anti-collision tube 113; one end of the anti-collision tube 113 is located in the first chamber body 1112 and is connected to the inner wall of the first hydraulic cylinder 111; the other end of the anti-collision tube 113 extends out of the first chamber body 1112 along a preset direction; the second hydraulic cylinder 112 and at least part of the lifting mechanism 110 are located in the anti-collision tube 113.

[0056] In this embodiment, the extension direction of the anti-collision tube 113 is the same as the movement direction of the second piston 1121, both of which are vertical directions. Therefore, the second piston 1121 can drive the support mechanism 120 to move in the vertical direction, that is, to achieve lifting.

[0057] The second hydraulic cylinder 112 is disposed in the anti-collision tube 113 to protect the second hydraulic cylinder 112 and prevent some external factors from damaging the second hydraulic cylinder 112 during high-altitude operations, for example, a bird in the sky collides with the lifting span frame 100 during flight.

[0058] At least a portion of the support mechanism 120 is disposed in the anti-collision tube 113 to protect the support mechanism 120. However, since the support mechanism 120 is used to support the transmission line, the portion of the support mechanism 120 used to support the transmission line extends out of the anti-collision tube 113.

[0059] Since one end of the anti-collision tube 113 is connected to the inner wall of the first hydraulic cylinder 111, it can be understood that the anti-collision tube 113 separates the first chamber body 1112 from the second chamber body 1122. In order to enable the first chamber body 1112 and the second chamber body 1122 to communicate with each other so that the liquids in the first chamber body 1112 and the second chamber body 1122 can circulate with each other, the jacking mechanism 110 further includes a connecting tube 114, which passes through the anti-collision tube 113, and the two ends of the connecting tube 114 are respectively connected to the first chamber body 1112 and the second chamber body 1122.

[0060] According to the above structure settings, please refer to Figure 1 and Figure 2 In order to further improve the stability of the lifting and crossing frame 100, the lifting mechanism 110 also includes an anti-tilt tube 115 and a plurality of reinforcement tubes 116; the anti-tilt tube 115 is sleeved on the second hydraulic cylinder 112, and both ends of each reinforcement tube 116 are respectively connected to the outer wall of the anti-tilt tube 115 and the inner wall of the anti-collision tube 113; the plurality of reinforcement tubes 116 are arranged in a circular array around the axis of the anti-tilt tube 115.

[0061] Specifically, the inner wall of the anti-tilt tube 115 is in contact with the outer wall of the second hydraulic cylinder 112, and by strengthening the connection between the tube 116 and the outer wall of the anti-tilt tube and the inner wall of the anti-collision tube 113, the second hydraulic cylinder 112 does not have the space to move to the left or right, thereby restricting the movement of the second hydraulic cylinder 112, preventing the second hydraulic cylinder 112 from tipping over, improving the stability of the structure, preventing the power transmission line from falling from a high altitude, and improving the safety of the lifting and crossing frame 100.

[0062] For further information, please refer to Figure 1-Figure 2 The frame 140 includes a limiting cover 142 and a bracket 143. The first hydraulic cylinder 111 is located in the limiting cover 142, thereby positioning the first hydraulic cylinder 111 and limiting the movement of the first chamber body 1112 of the first hydraulic cylinder 111. The bracket 143 is connected to the limiting cover 142, and a cylinder acting on the first piston 1111 is connected to the bracket 143, so that the first piston 1111 can move under the drive of the cylinder.

[0063] For further information, please refer to Figure 1-Figure 3 , Figure 3 This is a schematic diagram of the structure of the support mechanism 120 provided in this embodiment.

[0064] The supporting mechanism 120 includes a connecting member 121, a first supporting member 122 and a plurality of second supporting members 123. The connecting member 121 is connected to the second piston 1121. One end of the first supporting member 122 can be slidably connected to the connecting member 121. One ends of the plurality of second supporting members 123 can be movably connected to the connecting member 121. The plurality of second supporting members 123 are arranged in a circular array around the first supporting member 122. The first supporting member 122 and the plurality of second supporting members 123 are both used to support the transmission line.

[0065] It should be noted that the first support member 122 and the second support member 123 are arranged at an angle, and the connecting plate moves in the vertical direction under the drive of the second piston 1121, wherein the first support member 122 also moves in the vertical direction, and then, since the second support member 123 and the connecting member 121 can be rotatably matched, the movable end of each second support member 123 rotates around its connecting end during the process of the second piston 1121 driving the vertical movement. One end of the second support member 123 connected to the connecting member 121 is the connecting end, and the other end of the second support member 123 is the movable end.

[0066] Specifically, when the support mechanism 120 moves upward, the second support member 123 also moves upward, and its movable end gradually moves away from the first support member 122. When the support mechanism 120 moves downward, the second support member 123 also moves downward, and its movable end gradually approaches the first support member 122.

[0067] It can be understood that in the process of the lifting spanning frame 100 conveying the power lines upward, the distance between different power lines gradually increases, thereby avoiding the series connection between the power lines and avoiding potential safety hazards.

[0068] According to the above structure settings, please refer to Figure 1-Figure 3 The support mechanism 120 further includes a support tube 124 ; the support tube 124 is provided with a receiving cavity 1241 with an opening at one end, and the connecting member 121 is disposed in the receiving cavity 1241 .

[0069] Specifically, both ends of the support tube 124 are open, and the support tube 124 is a through cavity. However, the connecting piece 121 is arranged in the cavity, separating the cavity into two parts, one of which is used to accommodate the support mechanism 120, therefore, this part is the accommodating cavity 1241, and one end of the accommodating cavity 1241 is blocked by the connecting piece 121, so only one end is open.

[0070] Furthermore, the support tube 124 is disposed in the anti-collision tube 113 , and the anti-collision tube 113 is used to protect the support tube 124 . The axis of the support tube 124 coincides with the axis of the anti-collision tube 113 .

[0071] In this embodiment, the other end of the first support member 122 and the other end of the second support member 123 extend out of the accommodating cavity 1241 along a preset direction; the plurality of second support members 123 are all in contact with the end of the support tube 124. Thus, the support tube 124 can limit the rotation of the second support member 123 to prevent the second support member 123 from rotating too much, causing the transmission line to move downward.

[0072] For further information, please refer to Figure 1-Figure 4 , Figure 4 This is a schematic structural diagram of the first movable tube 125, the positioning member 127 and the adjusting tube 128 provided in this embodiment.

[0073] The supporting mechanism 120 also includes a first movable tube 125 and a second movable tube 126. The first movable tube 125 can be movably mounted on the second movable tube 126. The first movable tube 125 is provided with a first pipe 1251 with openings at both ends, and the second movable tube 126 is provided with a second pipe 1261 with an opening at one end. The first pipe 1251 and the second pipe 1261 are connected and are both used to accommodate the cylinder. The outer wall of the first movable tube 125 is rotatably connected to one end of the second supporting member 123; the other end of the second movable tube 126 is connected to one end of the first supporting member 122.

[0074] It should be noted that when the second piston 1121 moves to the extreme position, that is, the second piston 1121 can no longer move upward, the power transmission line supported by the first support member 122 and the second support member 123 may not have reached the preset height. Therefore, the first movable tube 125 is provided to drive the first support member 122 and the second support member 123 to move.

[0075] The plurality of second support members 123 are arranged in a circular array around the first support member 122. It can be understood that the first support member 122 is located at the center of the plurality of second support members 123. The transmission line supported by the first support member 122 is located at the center of the transmission line. The transmission lines in the transmission line are arranged in a pyramid shape, with the middle transmission line having the highest height and the transmission lines on both sides having the lowest height.

[0076] In this embodiment, in order to ensure that the height of the intermediate transmission line is the highest, a second movable tube 126 connected to the first support member 122 is provided to drive the first support member 122 to move in the vertical direction.

[0077] The first pipe 1251 and the second pipe 1261 respectively accommodate different cylinders. The cylinder in the first pipe 1251 acts on the first movable pipe 125 to drive the first movable pipe 125 and the second movable pipe 126 to move in the vertical direction. The cylinder in the second pipe 1261 acts on the second movable pipe 126 to drive the second movable pipe 126 to move in the vertical direction.

[0078] Based on the above, please refer to Figure 1-Figure 4 In this embodiment, the support mechanism 120 further includes a positioning member 127, which is disposed in the first movable tube 125 and connected to the first movable tube 125; the second movable tube 126 is provided with a positioning hole 1262, and the positioning member 127 is movably matched with the positioning hole 1262. Specifically, the support mechanism 120 positions the first movable tube 125 and the second movable tube 126 through the positioning hole 1262 and the positioning member 127 to prevent the first movable tube 125 and the second movable tube 126 from being misaligned. In addition, since the first movable tube 125 is sleeved on the second movable tube 126, the second movable tube 126 can move relative to the first movable tube 125, and the positioning member 127 can also play a guiding role to prevent the second movable tube 126 from moving obliquely upward, thereby preventing the second movable tube 126 from tipping over.

[0079] In addition, the support mechanism 120 also includes an adjusting tube 128, which is sleeved on at least a portion of the first movable tube 125. The second support member 123 is rotatably connected to the intersection of the outer wall of the first movable tube 125 and the upper surface of the adjusting tube 128. The adjusting tube 128 can support the second support member 123 to prevent the second support member 123 from sagging.

[0080] For further information, please refer to Figure 1-Figure 5 , Figure 5 A schematic diagram of the structure of the protection mechanism 130 provided in this embodiment. In this embodiment, the protection mechanism 130 includes a connecting plate 131, a telescopic member 132, and a plurality of reinforcing members 133; the connecting plate 131 is movably sleeved on the second hydraulic cylinder 112, the telescopic member 132 and the plurality of reinforcing members 133 are both located between the first hydraulic cylinder 111 and the connecting plate 131, and the two ends of the telescopic member 132 are respectively connected to the connecting plate 131 and the first hydraulic cylinder 111. Specifically, one end of the telescopic member 132 is connected to the limiting cover 142, and the limiting cover 142 is connected to the first hydraulic cylinder 111, so the telescopic member 132 is connected to the first hydraulic cylinder 111.

[0081] The connecting plate 131 can be movably mounted on the anti-collision tube 113 to position the protection mechanism 130 , and the telescopic member 132 can be telescoped along a preset direction, ie, the vertical direction, thereby driving the reinforcement member 133 and the connecting plate 131 to move along the vertical direction.

[0082] Furthermore, one ends of the multiple reinforcements 133 are rotatably connected to the connecting disk 131, and are arranged in a circular array around the axis of the connecting disk 131; when the telescopic member 132 is gradually shortened along a preset direction, the other ends of the multiple reinforcements 133 are gradually away from the telescopic member 132; the multiple reinforcements 133 are used to gradually be inserted into the ground when the telescopic member 132 is gradually shortened along a preset direction.

[0083] As a result, the telescopic member 132 is shortened, and the connecting plate 131 and the reinforcement member 133 move downward. Since the length of the reinforcement member 133 remains unchanged, the reinforcement member 133 will be inserted into the ground, thereby playing a role similar to that of a foundation, thereby improving the stability of the lifting and spanning frame 100 and preventing the lifting and spanning frame 100 from tipping over.

[0084] During the downward movement of the reinforcement 133, the end inserted into the ground will gradually move away from the telescopic member 132. It can be understood that the reinforcement 133 moves obliquely downward and is inserted into the ground, and the reinforcement 133 continues to move downward, thereby gradually increasing the contact area between the reinforcement 133 and the ground and improving stability.

[0085] It should be noted that the telescopic member 132 is arranged between the second hydraulic cylinder 112 and the plurality of reinforcing members 133; therefore, in this embodiment, the reinforcing member 133 is away from the telescopic member 132, that is, the reinforcing member 133 expands outward to avoid the first hydraulic cylinder 111 or the telescopic member 132 from hindering the movement of the reinforcing member 133.

[0086] It should also be noted that the limiting cover 142 is provided with a guide surface, and the guide surface is used to guide the reinforcement member 133 to move in a direction away from the telescopic member 132, so that the reinforcement member 133 moves obliquely downward and is inserted into the ground.

[0087] According to the above structural arrangement, in the present embodiment, the protection mechanism 130 further includes a protection tube 134; one end of the protection tube 134 is connected to the connecting disk 131; the protection tube 134 is provided with a third pipe 1341 with openings at both ends, and at least a portion of the opening at one end of the third pipe 1341 is blocked by the connecting disk 131; one end of the telescopic member 132 extends into the third pipe 1341 and is connected to the connecting disk 131.

[0088] It can be understood that the protective tube 134 surrounds at least a portion of the telescopic member 132 to protect the telescopic member 132 and prevent damage to the telescopic member 132 by external factors, and the protective tube 134 will not affect the normal extension and retraction of the telescopic member 132 .

[0089] Furthermore, in this embodiment, there are multiple telescopic members 132, which are arranged around the axis of the connection plate 131 to prevent the connection plate 131 from tilting during the downward movement. Furthermore, multiple reinforcement members 133 are arranged in a circular array around the axis of the connection plate 131 to ensure that the reinforcement members 133 are inserted into the ground at the same length to prevent the lifting spanning frame 100 from tipping over.

[0090] In addition, the protection mechanism 130 also includes a plurality of elastic members 135, and the plurality of elastic members 135 correspond one to one with the plurality of reinforcement members 133, and both ends of each elastic member 135 are respectively connected to the outer wall of the protection tube 134 and the corresponding reinforcement member 133; when the reinforcement member 133 is inserted into the ground, the elastic member 135 is stretched, so that after the construction is completed, the telescopic member 132 is extended to make the reinforcement member 133 move upward, and after the reinforcement member 133 is separated from the ground, the elastic member 135 can quickly reset the reinforcement member 133, thereby reducing the space utilization rate of the lifting mechanism.

[0091] For further information, please refer to Figure 1-Figure 5 In this embodiment, the protection mechanism 130 also includes a reinforcement tube 136 and a reinforcement plate 137. The reinforcement tube 136 and the reinforcement plate 137 are connected to the connecting plate 131 and can be movably mounted on the anti-collision tube 113. In addition, the axis of the reinforcement tube 136, the axis of the connecting plate 131 and the axis of the anti-collision tube 113 coincide with each other. Under the joint action of the reinforcement member 133, the reinforcement tube 136 and the reinforcement plate 137, the anti-collision tube 113 is prevented from tipping over, thereby improving the stability of the lifting and crossing frame 100.

[0092] In summary, the present invention provides a lifting and crossing frame 100, which is provided with a jacking mechanism 110, and the jacking mechanism 110 includes a first hydraulic cylinder 111 and a second hydraulic cylinder 112; the first hydraulic cylinder 111 includes a first piston 1111 and a first chamber body 1112; the first piston 1111 and the first chamber body 1112 are movably matched; the second hydraulic cylinder 112 includes a second piston 1121 and a second chamber body 1122; the second piston 1121 and the second chamber body 1122 are movably matched; wherein, the first chamber body 1112 is connected to the second chamber body 1122; so that when the first piston 1111 moves relative to the first chamber body 1112 to gradually reduce the volume of the first chamber body 1112, the second piston 1121 moves relative to the first chamber body 1112 to gradually increase the volume of the second chamber body 1122. The lifting mechanism 110 changes the volume of the first chamber body 1112 by driving the first piston 1111 to move through the linkage relationship between the first hydraulic cylinder 111 and the second hydraulic cylinder 112; however, since the first chamber body 1112 and the second chamber body 1122 are closed structures, the total volume of the first chamber body 1112 and the second chamber body 1122 will not change, so when the volume of the first chamber body 1112 decreases, the volume of the second chamber body 1122 increases, thereby causing the second piston 1121 to move.

[0093] In addition, the support mechanism 120 in the lifting span frame 100 is used to support the power transmission line; the support mechanism 120 is connected to the second piston 1121, and the second piston 1121 drives the support mechanism 120 to move along a preset direction; therefore, during the movement of the second piston 1121, the second piston 1121 can drive the support mechanism 120 to move, thereby realizing the lifting and lowering of the support mechanism 120.

[0094] The lifting span frame 100 also includes a protection mechanism 130, which is connected to the lifting mechanism 110 and the supporting mechanism 120 and is used to be inserted into the ground. In addition, the lifting mechanism 110 is also provided with structures such as an anti-collision pipe 113, an anti-tilt pipe 115 and a reinforcement pipe 116 to protect the second hydraulic cylinder 112, and can also prevent the second hydraulic cylinder 112 from tipping over with the supporting assembly and the transmission line, thereby improving the stability of the lifting mechanism and preventing the transmission line from falling from a high altitude, thereby improving the safety of the lifting span frame 100. The lifting span frame 100 has the advantages of simple structure, low cost and low failure rate.

[0095] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
