Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage switch transportation, in particular to an adjustment mechanism and a high-voltage switch transportation trolley. Background Art

[0002] High-voltage switchgear is widely used in power distribution systems to receive and distribute electric energy. It can put a part of the power equipment or lines into or out of operation according to the needs of the power grid operation, and can also quickly cut off the faulty part from the power grid when the power equipment or line fails, thereby ensuring the normal operation of the fault-free part of the power grid and the safety of the equipment and operation and maintenance personnel. Therefore, high-voltage switchgear is a very important power distribution equipment, and the related operations of high-voltage switchgear are even more important.

[0003] At present, the high-voltage switch cabinet of the hydropower station unit needs to transfer the switch trolley to the switch cabinet during daily equipment maintenance or line maintenance. Therefore, a transfer trolley is needed to transport the switch trolley to the switch cabinet. When the existing transfer trolley is pushed or pulled out into the switch cabinet, the transfer trolley needs to be connected to the switch cabinet rail first. The existing connection method requires the threaded rod in front of the transfer trolley to be rotated and inserted into the threaded hole of the switch cabinet, which is not convenient for operation during connection and disassembly. Therefore, we propose a snap-on connection method. Secondly, the height of the transfer trolley needs to be adjusted multiple times to achieve a height that matches the switch cabinet rail, so as to facilitate the transportation of the switch trolley to the switch cabinet for work. Since the height adjustment of the transfer trolley is to adjust its supporting screws one by one by turning the handle, when the transfer trolley is stored after use or the height of the transfer trolley needs to be greatly adjusted, the method of turning the handle to adjust multiple screws one by one causes great waste of manpower and time, which brings inconvenience to the workers. Therefore, we propose an adjustment mechanism to achieve rapid adjustment of the height of the transfer trolley.

[0004] In view of the above problems, we propose an adjustment mechanism and a high-voltage switch transfer trolley. Utility Model Content

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0031] Example 1

[0032] Reference Figures 1 to 4 , which is the first embodiment of the utility model. This embodiment provides an adjustment mechanism, which can adjust the height of the transfer trolley when transferring the switch trolley to adapt to the height of the switch cabinet guide rail and ensure that the switch trolley is pushed into the switch cabinet. It includes a supporting base plate 100, an adjustment component 200 rotatably arranged on the supporting base plate 100, and a locking component 300 arranged on the supporting base plate 100 and the adjustment component 200 and matching with the adjustment component 200. The adjustment component 200 includes a lifting member 201 rotatably installed on the supporting base plate 100, and a fixing member 202 arranged in the supporting base plate 100 and matching with the lifting member 201. The locking component 300 includes an extrusion member 301 arranged on the supporting base plate 100 and matching with the fixing member 202, and a clamping member 302 arranged on the lifting member 201 and matching with the extrusion member 301.

[0033] In this embodiment, the support base plate 100 is used to install the entire adjustment mechanism. The adjustment components 200 and the locking components 300 each have four groups, which are matched with each other. The lifting member 201 is rotatably installed on the support base plate 100 to achieve the adjustment of the height of the switch trolley. The fixing member 202 is arranged in the support base plate 100 to install the lifting member 201 so that its horizontal position is always fixed on the support base plate 100. The extrusion member 301 is rotatably arranged on the support base plate 100 to extrude the fixing member 202. The clamping member 302 is arranged on the lifting member 201 to limit and unlock the fixing member 202.

[0034] Specifically, the lifting member 201 includes a through hole 201a opened in the supporting base plate 100, a threaded lifting rod 201b rotatably installed in the through hole 201a, and a rotating handle 201c fixedly installed at the bottom end of the threaded lifting rod 201b. The fixing member 202 includes a cavity 202a opened in the supporting base plate 100 and communicating with the through hole 201a, a semi-annular threaded sleeve 202b arranged in the cavity 202a, and a spring piece 202c arranged at the connection of the semi-annular threaded sleeve 202b.

[0035] In this embodiment, the through hole 201a is set through the supporting base plate 100, and is used to install the threaded lifting rod 201b and the semi-annular threaded sleeve 202b. The cavity 202a is communicated with the through hole 201a, and is used to install the semi-annular threaded sleeve 202b. The semi-annular threaded sleeve 202b is composed of two semi-rings, which are connected in the middle by a spring piece 202c, wherein one half of the semi-annular threaded sleeve 202b is fixedly connected to the inner wall of the cavity 202a, and the other half is provided with a certain gap from the inner wall of the cavity 201a. When the extrusion piece 301 does not extrude the semi-annular threaded sleeve 202b, the elastic force of the spring piece 202c bounces half of the semi-annular threaded sleeve 202b away, so that the two semi-annular threaded sleeves 202b are separated, so that the threaded lifting rod 201b can move up and down in the semi-annular threaded sleeve 202b.

[0036] When in use, rotating the handle 201c drives the threaded lifting rod 201b to rotate in the semi-annular threaded sleeve 202b, thereby realizing its lifting and lowering on the supporting base plate 100, further driving the lifting and lowering of the storage tray 601 thereon, and finally realizing the adjustment of the height of the transfer trolley.

[0037] Example 2

[0038] Reference Figures 1 to 5 , which is the second embodiment of the utility model. Different from the previous embodiment, this embodiment provides an unlocking function of the adjustment mechanism, which can realize the rapid adjustment of the height of the transfer trolley, including an extrusion piece 301, which includes an extrusion piece groove 301a opened on one side of the semi-annular threaded sleeve 202b, an extrusion cam 301b arranged on the supporting base plate 100 and located on the side of the semi-annular threaded sleeve 202b where the extrusion piece groove 301a is opened, and an operating rod 301c fixedly installed on the extrusion cam 301b, the clamping piece 302 includes a clamping piece installation groove 302a opened in the semi-annular threaded sleeve 202b and located on one side of the extrusion piece groove 301a, a clamping spring 302b elastically installed at the bottom end of the clamping piece installation groove 302a, a clamping column 302c fixedly connected to the clamping spring 302b, and a pressing connecting rod 302d fixedly arranged on the clamping column 302c; a clamping groove 302e is also opened on the extrusion cam 301b.

[0039] In this embodiment, the extrusion member groove 301a is provided on one side of the semi-annular threaded sleeve 202b, and is used to match the extrusion cam 301b. The extrusion cam 301b is rotatably mounted on the support base plate 100 and is arranged corresponding to the extrusion member groove 301a, and is used to squeeze and lock the semi-annular threaded sleeve 202b to close it, so as to fix the position of the threaded lifting rod 201b on the support base plate 100. The clamping member installation groove 302a is provided in the semi-annular threaded sleeve 202b and is located on one side of the extrusion member groove 301a, and is used to install the clamping spring 301a. 2b and a clamping column 302c, a clamping spring 302b is elastically installed at the bottom of the clamping component mounting groove 302a, one end of the clamping spring is fixedly welded to the bottom of the clamping component mounting groove 302a, and the other end is fixedly welded with a clamping column 302c, which is used to squeeze and support the clamping column 302c, so that the clamping column 302c can automatically reset after being squeezed back into the clamping component mounting groove 302a, and the clamping column 302c is used to be clamped into the clamping groove 302e on the extrusion cam 301b, so as to realize the locking of the extrusion cam 301b after it is rotated into the extrusion component groove 301a.

[0040] The rest of the structure is the same as that of Example 1.

[0041] When in use, when it is necessary to significantly adjust the height of the transfer trolley, first press the pressing connecting rod 302d to make the clamping column 302c retract into the clamping piece installation groove 302a and disengage from the clamping groove 302e, and then operate the operating rod 301c on the extrusion cam 301b to drive the extrusion cam 301b to rotate, so that the raised part on the extrusion cam 301b is disengaged from the extrusion piece groove 301a. At this time, the two half rings of the semi-annular threaded sleeve 202b are separated under the action of the spring piece 202c, and the object plate 601 is slightly moved toward the extrusion cam 301b to drive the threaded lifting rod 201b to move, so that the threaded lifting rod 201b is disengaged from the thread cooperation with the semi-annular threaded sleeve 202b, thereby realizing the rapid adjustment of the height of the threaded lifting rod 201b, and finally realizing the transfer. The height of the trolley can be quickly adjusted. After the adjustment is completed, the threaded lifting rod 201b is fine-tuned to match the fixed general thread of the semi-annular threaded sleeve 202b, and then the extrusion cam 301b is rotated to make the raised part on it enter the extrusion groove 301a, so that the semi-annular threaded sleeve 202b is closed from two semi-rings to a cylinder, thereby achieving reset. In this process, the raised part on the extrusion cam 301b will first squeeze the clamping column 302c to retract it. When the semi-annular threaded sleeve 202b is closed, the raised part on the extrusion cam 301b no longer squeezes the clamping column 302c. The clamping column 302c pops out and is clamped into the clamping groove 302e under the action of the clamping spring 302b, thereby locking the extrusion cam 301b and never achieving reset of the entire device.

It includes the adjustment mechanism in the above embodiment, and also includes a mounting base 400 fixedly connected to the support base plate 100, a sliding member 500 arranged at the lower end of the mounting base 400, and a transfer member 600 arranged on the threaded lifting rod 201b. The sliding member 500 includes a fixed block 501 arranged at the bottom end of the mounting base 400, and a universal wheel 502 rotatably installed at the bottom end of the fixed block 501. The transfer member 600 includes a storage tray 601 arranged on the threaded lifting rod 201b, a plug-in column 602 arranged at one end of the storage tray 601, and a driving connecting rod 603 fixedly connected to the plug-in column 602.

[0044] In this embodiment, the mounting base 400 is fixedly connected to the supporting base plate 100, and a total of four universal wheels 502 are installed on the bottom of the mounting base 400 in a rectangular distribution through the fixing block 501, which is used to facilitate the movement of the transfer cart. The storage tray 601 is rotatably connected to the threaded lifting rod 201b, and is used to place the switch trolley that needs to be transferred. Two plug-in columns 602 are provided at one end of the storage tray 601, which are used to match and plug with the plug-in holes on the switch cabinet to prevent the transfer trolley from deviating and causing safety accidents when pushing the switch trolley into the switch cabinet. The driving connecting rod 603 is arranged for transmission with the plug-in column 602, which is used to drive the plug-in and unlocking of the plug-in column 602, and the plug-in column 602 is slidably arranged at one end of the storage tray 601.

[0045] The rest of the structure is the same as that of Example 2.

[0046] When in use, push the transfer trolley to the front and rear of the switch cabinet rail, adjust it to a suitable height, operate the drive connecting rod 603 to make the plug-in column 602 plug into the plug-in hole at one end of the switch cabinet rail, and then push the switch trolley into the switch cabinet. After completion, move the drive connecting rod 603 to drive the plug-in column 602 out of the plug-in hole, thereby realizing rapid disassembly of the transfer trolley after being connected to the switch cabinet rail.
