[0029] Example 1
[0030] Reference Figure 1 and Figure 2 , which is the first embodiment of the utility model, provides a carrying platform, and the carrying platform includes a base 100 and a carrying plate 200.
[0031] Specifically, the carrying plate 200 is arranged above the base 100, and includes a leveling member 201, a guide rail 202, a locking member 203, an unloading plate 204, and an alignment member 205. The leveling member 201 is arranged at the four corners of the lower end of the carrying plate 200, the guide rail 202 is arranged above the carrying plate 200, the locking member 203 is arranged on the guide rail 202, the unloading plate 204 is detachably connected to the carrying plate 200, and the alignment member 205 is arranged in the middle of the carrying plate 200;
[0032] The carrier plate 200 is leveled by the leveling piece 201, and the spacing of the guide rails 202 is adjusted so that it can be used with switch cabinets of different specifications. The guide rails 202 are then locked by the locking piece 203. The unloading plate 204 can easily unload heavy switches, PTs (voltage transformers), and disconnectors, saving manpower. The alignment piece 205 is used to clamp the carrier plate 200 and the switch cabinet during transportation to prevent the carrier plate 200 from moving at will.
[0033] Specifically, the flattening member 201 includes a bolt 201a and a disc 201b. The lower end of the bolt 201a is rotatably matched with the base 100, and the disc 201b is arranged in the middle of the bolt 201a. The lower end of the bearing plate 200 is provided with a threaded hole 200a, and the threaded hole 200a is threadably matched with the bolt 201a.
[0034] It is worth noting that the disc 201b is fixedly connected to the bolt 201a. After the supporting plate 200 is moved to a predetermined position, the supporting plate 200 will tilt due to the uneven ground. At this time, the disc 201b can be rotated to adjust the height of the four end points of the supporting plate 200 so that the supporting plate 200 can reach a level.
[0035] Specifically, the carrying plate 200 is further provided with a slide groove 200 b, and the slide groove 200 b is arranged at the upper end of the carrying plate 200 .
[0036] Specifically, the guide rail 202 is provided with a slider 202a and a shell 202b. The slider 202a is slidably matched with the slide groove 200b, and the shell 202b is arranged on the side wall of the slider 202a; the shell 202b is provided with a square groove 202c, a rod groove 202d, a spring groove 202e, a side groove 202f, an opening 202g, and a locking groove 202h. The square groove 202c is arranged in the middle of the shell 202b, the rod groove 202d is arranged at the upper end of the square groove 202c, the spring groove 202e is arranged at the upper end of the square groove 202c, the side grooves 202f are arranged on both sides of the shell 202b and are connected with the square groove 202c, the opening 202g is arranged at the upper end of the shell 202b and is connected with the spring groove 202e, and the locking groove 202h is arranged on the side wall of the opening 202g.
[0037] Specifically, the locking member 203 includes an upper plate 203a, a connecting rod 203b, a pressure block 203c, a clamping rod 203d, and a first spring 203e. The connecting rod 203b is slidably matched with the rod groove 202d, one end of which is connected to the upper plate 203a, and the other end is rotatably matched with the pressure block 203c. The pressure block 203c is slidably matched with the square groove 202c, the clamping rod 203d is slidably matched with the side groove 202f, and the first spring 203e is arranged between the spring groove 202e and the end surface of the upper plate 203a.
[0038] It is worth noting that a rubber round head is provided at one end of the clamping rod 203d away from the pressure block 203c, which can increase the friction between the clamping rod 203d and the side wall of the slide groove 200b. In the initial state, the first spring 203e is at its original length. At this time, the clamping rod 203d is completely located in the side groove 202f, and the guide rail 202 can slide arbitrarily in the slide groove 200b.
[0039] Specifically, a limit block 203f is provided on the side of the upper plate 203a, first inclined surfaces 203g are provided on both sides of the pressing block 203c, and a second inclined surface 203h is provided at one end of the pressing rod 203c, and the first inclined surface 203g is in contact with the second inclined surface 203h;
[0040] The limiting block 203f is consistent with the outline of the opening 202g. In the initial state, the lower end of the first inclined surface 203g is in contact with the upper end of the second inclined surface 203h.
[0041] When the guide rail 202 needs to be locked in the current position, it is only necessary to align the limit block 203f with the opening 202g, press the upper plate 203a, and the first inclined surface 203g squeezes the second inclined surface 203h, so that the rubber round head of the clamping rod 203d fits tightly with the side wall of the slide groove 200b, thereby limiting the movement of the guide rail 202. At this time, the upper plate 203a is located in the limit groove 202h. If the upper plate 203a is rotated again, the limit block 203f is restricted by the upper end of the limit groove 202h, which hinders the upward movement of the pressing block 203c.
[0042] Specifically, the front end of the carrier plate 200 is further provided with a mounting groove 200c and an alignment groove 200d; the unloading plate 204 includes a fixed plate 204a and a rotating plate 204b, and the rotating plate 204b is rotatably matched with the fixed plate 204a; an insert block 204c is provided at one end of the fixed plate 204a, and the insert block 204c is snap-fitted with the mounting groove 200c;
[0043] It is worth noting that the tail of the plug block 204c is bent to prevent it from falling off after connection. In the initial state, the unloading plate 204 is not connected to the carrier plate 200. Only when the object on the carrier plate 200 needs to be unloaded, the plug block 204c needs to be inserted into the installation groove 200c and connected to the carrier plate 200, and then the angle of the rotating plate 204b is adjusted to slide the object down along the carrier plate 200 during unloading, which saves effort.
[0044] Specifically, the alignment member 205 includes an alignment rod 205a, a column 205b, a second spring 205c, and a hook 205d. The alignment rod 205a is disposed at the front end of the carrier plate 200, the column 205b is disposed below the carrier plate 200, the second spring 205c connects the column 205b and the middle of the hook 205d, and the hook 205d extends out of the alignment slot 200d.
[0045] It is worth noting that the middle part of the hook 205d is hinged to the lower end of the supporting plate 200, and there is a slot corresponding to the alignment rod 205a and the hook 205d in the switch cabinet. When the supporting plate 200 is connected to the switch cabinet, the alignment rod 205a and the hook are inserted into the corresponding slots, and the hook 205d is engaged with the slot to prevent the supporting plate 200 from moving when transferring objects.
[0046] When in use, first move the carrier plate 200 to a predetermined position, rotate the disc 201b for leveling, then insert the alignment rod 205a and the hook 205d into the corresponding slots in the switch cabinet to fix the carrier plate 200, then move the guide rail 202 to a suitable position according to the specifications of the switch cabinet, press the upper plate 203a and rotate it to lock the guide rail 202, and when it is necessary to remove the object on the carrier plate 200, install the unloading plate 204, and then slide the object along the unloading plate 204.
[0047] Example 2
[0048] Reference Figure 1 to Figure 6 , which is the second embodiment of the utility model, and further provides a trolley for 10kv switch and pt maintenance, including a load-bearing platform, a trolley 300 and a lifting member 400.
[0049] Specifically, the lifting member 400 is disposed between the base 100 and the cart 300; in this embodiment, the lifting member 400 may be a cylinder, a hydraulic cylinder, a scissor lift, etc.
[0050] Specifically, the cart 300 is provided with a handle 301 at the upper end and a pulley 302 at the lower end; it is worth noting that the bottom pulley 302 has a locking function.
[0051] When in use, the trolley is pushed to a predetermined position by the push handle 301 and the pulley 302 is locked, and then the lifting member 400 is opened to drive the carrying platform to rise and fall, so that the top surface of the carrying plate 100 is flush with the plane where the 10kV switch is located.
[0052] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
