[0035] See also Figure 1 and Figure 2 , Figure 1 A three-dimensional view of an electric power equipment transfer platform according to an embodiment of the present application is shown; Figure 2The figure shows a three-dimensional view of the power equipment transfer platform of an embodiment of the present application from another angle, wherein the Z direction in the figure is the vertical direction. The power equipment transfer platform (hereinafter referred to as the transfer platform) provided in an embodiment of the present application is used in conjunction with an external traction device. The transfer platform includes a mobile frame 1 and a limiting mechanism 2. The mobile frame 1 is used for being towed and moved by an external traction device. The limiting mechanism 2 is arranged on the mobile frame 1. Figures 3 to 5 The limiting mechanism 2 includes a bottom plate 21, an elastic member 22 and a vertically arranged support column 23. There are multiple support columns 23 and elastic members 22, and the support columns 23 correspond to the elastic members 22 one by one. The bottom plate 21 is installed on the mobile frame 1. One end of the elastic member 22 is connected to the bottom plate 21, and the other end is connected to the corresponding support column 23. The support column 23 can be raised and lowered relative to the bottom plate 21. The elastic member 22 always has a tendency to drive the support column 23 to rise. The end of the support column 23 away from the bottom plate 21 is used to abut against the power equipment to be transported.

[0036] The mobile frame 1 provides support for the limiting mechanism 2. The electric equipment to be transported is placed on the limiting mechanism 2. The mobile frame 1 is pulled by the traction device to move, thereby driving the entire transfer platform and the electric equipment to move, and realizing the purpose of transporting the electric equipment in the substation. Since the two opposite ends of the elastic member 22 are respectively connected to the bottom plate 21 and the support column 23, and the support column 23 can be lifted relative to the bottom plate 21, when the electric equipment needs to be transported, the electric equipment to be transported is placed on the upper end of the support column 23. Due to the heavy weight of the electric equipment, under the action of the gravity of the electric equipment, the support column 23 is squeezed downward by the electric equipment, so that the support column 23 squeezed downward by the support column 23 overcomes the elastic force of the elastic member 22, and the support column 23 not squeezed downward by the electric equipment remains unchanged in the vertical direction, thereby forming a pit near the bottom of the electric equipment, so that the electric equipment is limited in the pit, thereby limiting the sliding of the electric equipment on the transfer platform, reducing the risk of movement or tipping of the electric equipment during the transportation process, reducing the tedious work of binding the electric equipment by the binding rope, saving manpower and material resources, and being conducive to improving the transportation efficiency of the electric equipment. In addition, the transfer platform with this structure can automatically adjust the shape and size of the pit on the limiting mechanism according to the different shapes of the power equipment, and can be applied to power equipment of different shapes, so it has high applicability.

[0037] See also Figure 5 and Figure 6In some embodiments, each support column 23 includes a column body 231 and a convex portion 232 protruding from the outer peripheral side of the column body 231. The elastic member 22 is sleeved on the outer peripheral side of the column body 231, and one end of the elastic member 22 away from the bottom plate 21 is connected to the convex portion 232. When the power device presses the support column 23 downward, the power device contacts the upper end of the column body 231. The convex portion 232 is provided on the outer peripheral side of the column body 231, and the convex portion 232 provides a connection space for the elastic member 22, so as to facilitate the assembly of the elastic member 22 and the support column 23. In this example, the elastic member 22 is a compression spring.

[0038] See also Figure 4 In some embodiments, the limiting mechanism 2 further includes a guide plate 24 movably arranged on the upper side of the bottom plate 21, the guide plate 24 is provided with a plurality of guide holes 241, the guide holes 241 penetrate the top and bottom of the guide plate 24, the guide holes 241 correspond to the column bodies 231 one by one, the column bodies 231 movably penetrate the corresponding guide holes 241, one end of the column body 231 away from the bottom plate 21 protrudes from the top of the guide plate 24, and the bottom of the guide plate 24 is supported on the protrusion 232. By movably penetrating the plurality of column bodies 231 in the guide holes 241 of the guide plate 24, the moving direction of the support column 23 can be guided by the guide plate 24, which is conducive to preventing the support column 23 from tilting.

[0039] See also Figure 1 and Figure 2 In some embodiments, the limiting mechanism 2 includes multiple limiting mechanisms 2, which are spaced apart on the mobile rack 1. The multiple limiting mechanisms 2 can increase the number of limiting mechanisms for the power equipment, so that multiple power equipment can be placed on the same transfer platform at the same time, so as to transfer multiple power equipment at the same time, which is beneficial to improve the transfer efficiency of the transfer platform. In the specific implementation process, the power equipment required for the test process is placed on the corresponding limiting mechanism 2. After the power equipment is transferred to the test position by the transfer platform, the staff can connect each power equipment through a wire or a data cable on the mobile rack 1 to assemble each power equipment into a test device. In this way, the power equipment can be debugged or tested on the mobile rack 1 without removing the power equipment from the transfer platform. Multiple limiting mechanisms 2 are spaced apart on the mobile rack 1, which is beneficial to keep the power equipment at a safe distance during debugging and testing.

[0040] Continue reading Figure 1 and Figure 2 In the figure, the Y direction is the first direction, and the X direction is the second direction. In this example, there are ten limiting mechanisms 2, and the ten limiting mechanisms 2 are evenly divided into two rows. The two rows of limiting mechanisms 2 are spaced along the first direction (i.e., the X direction), and all the limiting mechanisms 2 in the same row are spaced along the second direction (Y direction). Specifically, the first direction is the length of the mobile frame 1, and the second direction is the width direction of the mobile frame 1.

[0041] In other examples, the number of the limiting mechanisms 2 may be set to one, two, three, etc. as needed, and the distribution positions of the limiting mechanisms 2 may be flexibly adjusted as needed.

[0042] See also Figure 2 In some embodiments, the top of the mobile frame 1 is recessed downward to provide a plurality of mounting positions 11, the mounting positions 11 correspond to the limiting mechanisms 2 one by one, the limiting mechanisms 2 are provided in the corresponding mounting positions 11, the bottom of the mounting positions 11 supports the bottom plate 21 of the limiting mechanisms 2, and one end of each support column 23 away from the bottom plate 21 protrudes from the top of the mobile frame 1. The mounting positions 11 are mainly used to position the limiting mechanisms 2 so as to optimize the distribution position of the limiting mechanisms 2.

[0043] In one embodiment, refer to Figure 4 The bottom plate 21 is provided with a through hole 211 that passes through the top and bottom thereof. There are multiple through holes 211, and the through holes 211 correspond to the support columns 23 one by one. The support columns 23 are movably arranged in the corresponding through holes 211, so that the support columns 23 can partially pass through the bottom. During the lifting process of the support columns 23, the inner side walls of the through holes 211 can guide the support columns 23, further preventing the moving direction of the through holes 211 from tilting, which is beneficial to improving the smoothness of the lifting and lowering of the support columns 23. In order to prevent the position of the mounting position 11 from interfering with the support columns 23, an avoidance position is provided at the bottom of the mounting position 11, and the avoidance position is used to avoid the support columns 23. It should be noted that in actual implementation, the support columns 23 can also be arranged at intervals on the upper side of the bottom plate 21.

[0044] See also Figure 1 and Figure 2 The mobile frame 1 includes a frame body 12 and a moving assembly 13. The two moving assemblies 13 are respectively located on opposite sides of the frame body 12 in the first direction (i.e., the X direction). Each group of moving assemblies 13 includes a cantilever 131 and a moving wheel 132. The moving wheel 132 is rotatably connected to the frame body 12 through the cantilever 131. The frame body 12 provides support for the entire transfer platform. Under the traction of the external traction equipment, the entire transfer platform is moved by the moving wheels 132 on opposite sides of the frame body 12 in the first direction. It can be understood that the road conditions in the substation are changeable. For example, the rails in some newly built converter stations usually have obstacles that are more than 15 cm above the ground. The moving wheel 132 is rotatably connected to the frame body 12 through the cantilever 131. When the moving wheel 132 encounters an obstacle, it can drive the cantilever 131 to rotate relative to the mobile frame 1, so that the moving wheel 132 crosses the obstacle, thereby improving the ability of the transfer platform to adapt to the road conditions in the substation.

[0045] Preferably, the moving wheel 132 is a Mecanum wheel. The Mecanum wheel is an omnidirectional wheel that is widely used at present. It is widely used due to its flexibility and diversity of movement. Setting the moving wheel 132 as a Mecanum wheel facilitates the staff to adjust the position of the transfer platform within different ranges according to actual needs to adjust the position of the test device. Of course, in actual implementation, the type of the moving wheel 132 can be flexibly selected according to needs, for example, the moving wheel 132 is set to a universal wheel.

[0046] See also Figure 1 The mobile frame 1 also includes a shock absorber 133, which is located on the upper side of the cantilever 131. One end of the shock absorber 133 is connected to the cantilever 131, and the other end is connected to the mobile frame 1. The setting of the shock absorber 133 is conducive to reducing the bumpiness of the transfer platform, thereby reducing the risk of shaking or sliding of the power equipment on the transfer platform to ensure the safety of the power equipment.

[0047] See also Figure 2 The frame body 12 includes at least two brackets 121, and the at least two brackets 121 are arranged in sequence along the second direction (i.e., the Y direction), the second direction is perpendicular to the first direction, and the two adjacent brackets 121 are detachably connected. One of the two adjacent brackets 121 is provided with a notch 1211 on one side of the second direction, and the other is provided on the opening side of the notch 1211 to form an installation position 11 with the side wall of the notch 1211, and each bracket 121 is connected with a moving component 13 on two opposite sides of the first direction (i.e., the X direction). By setting two adjacent brackets 121 to be detachably connected, the number of brackets 121 can be increased or decreased as needed, so as to flexibly increase the number of limiting mechanisms 2, which is beneficial to improving applicability; a notch 1211 is set on one of the two adjacent brackets 121, and the other is set on the open side of the notch 1211, so that after the two brackets 121 are assembled together, the side wall of the installation position 11 also includes parts of the two brackets 121, so that the two brackets 121 jointly provide support for the limiting mechanism 2, which is beneficial to disperse the stress of the limiting mechanism 2 on the movable frame 1 on the two brackets 121.

[0048] In this example, the frame body 12 includes six brackets 121. In other examples, the number of the brackets 121 may be set to two, three, or four, etc., and the number of the brackets 121 is not specifically limited here.

[0049] See also Figure 7 and Figure 8Each bracket 121 includes a first main beam 1212, a second main beam 1213 and a plurality of supporting beams 1214. The length direction of the first main beam 1212 and the length direction of the second main beam 1213 are both parallel to the first direction. The plurality of supporting beams 1214 on the same bracket 121 are sequentially and spaced apart along the first direction. An installation position 11 is provided between two adjacent supporting beams 1214 on the same bracket 121. The first main beam 1212 is arranged on the upper side of the second main beam 1213. The first main beam 1212 is connected to the second main beam 1213 through the supporting beam 1214. The second main beam 1213 is located at the position of two adjacent brackets 121 and at least partially protrudes from the first main beam 1212 in the first direction to form a supporting portion 1215. The supporting portion 1215 is used to support the bottom plate 21. The supporting beam 1214 connects the first main beam 1212 and the second main beam 1213 into a whole to maintain the bracket 121 with sufficient structural strength; the supporting portion 1215 provides support for the bottom plate 21, and when in use, the bottom plate 21 can be directly placed on the supporting portion 1215, without the need to use other connecting components to connect the bottom plate 21 to the installation position 11.

[0050] Specifically, the second main beam 1213 includes two beam plates that are parallel and spaced apart along the first direction, and the supporting beam 1214 is connected between the two beam plates. The beam plate on the same bracket 121 protrudes at least out of the first main beam 1212 in the second direction. After the two brackets 121 are assembled, the beam plate can be positioned opposite the installation position 11 to form a support portion 1215.

[0051] Continue reading Figure 7 and Figure 8 The cantilever 131 includes a support arm 1311 and a connecting seat 1312. The moving wheel 132 and the support arm 1311 are respectively located on opposite sides of the connecting seat 1312 and are rotatably connected. One end of the support arm 1311 away from the connecting seat 1312 is rotatably connected to the second main beam 1213. The two main beams on the same second main beam 1213 are connected at one end in the first direction by a first connecting bolt 1313. The screw of the first connecting bolt 1313 is movably passed through one end of the support arm 1311, and the connecting seat 1312 is provided with a second connecting bolt 1314. The screw of the second connecting bolt 1314 is movably passed through the other end of the support arm 1311, so that the support arm 1311 can rotate around the axis of the screw of the first connecting bolt 1313, and the connecting seat 1312 can rotate around the axis of the screw of the second connecting bolt 1314. The moving wheel 132 can adapt to changes in road conditions through the rotation of the support arm 1311.

[0052] Further, see Figure 8A third connecting bolt 1315 is provided at one end of the first main beam 1212 in the first direction, and the screw of the third connecting bolt 1315 is movably inserted into one end of the shock absorber 133. The connecting seat 1312 is provided with a fourth connecting bolt 1316, and the screw of the fourth connecting bolt 1316 is movable through the other end of the shock absorber 133, so that the shock absorber 133 can adapt to road conditions along with the cantilever 131.
