[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0033] 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.

[0034] 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.

[0035] Example 1

[0036] Reference Figures 1 to 13 , which is the first embodiment of the present invention, and this embodiment provides an electric transport trolley, which includes a transport assembly 200, including a support member 201, two clamping members 202 symmetrically installed on the top of the support member 201, a positioning member 203 arranged inside the support member 201, a moving member 204 arranged at the bottom of the support member 201, and a control handrail 205 installed on the top of the support member 201; the support member 203 drives the extrusion frame 202d included in the two clamping members 202 to move from both sides of the support plate 201a to the middle by lifting the support plate 201a; the clamping member 202 realizes the positioning of the positioning member 203 by moving the push plate 202f.

[0037] The support member 201 is used for supporting and carrying the main component 100, the clamping member 202 is used for clamping the meter box 104 in the main component 100, and the positioning member 203 is used for positioning the pallet 101, which effectively prevents the pallet 101 from falling off during transportation and ensures stable transportation. The setting of the moving member 204 can drive the device to move, and the moving member 204 can move on the stairs, which can adapt to different transportation conditions and expand the scope of use of the device, thereby enabling the electric transport trolley to have the ability to pass and stability on complex terrains such as stairs and slopes, ensuring smooth driving in various environments, and the operation of the device can be achieved by controlling the handrail 205.

[0038] When in use, the device is moved by the moving member 204, so that the device moves to the area where the main assembly 100 is located, and the through grooves on both sides and the through groove in the middle of the support plate 201a are aligned with the support legs 102 and the bearing block 103 in the main assembly 100 respectively, and the device is moved so that the support plate 201a reaches directly below the tray 101, and then the support member 201 is started, and the support member 201 can drive the meter box 104 on the tray 101 to move upward. During the movement, the support member 201 drives the clamping member The extrusion frame 202d in 202 moves from both sides of the support plate 201a to the middle to clamp the meter box 104 placed on the pallet 101 to ensure stability during operation. The setting of the moving part 204 can change the angle between the adjusting frame 204d and the support frame 201a by pushing the adjusting frame 204d through the cylinder 204l when encountering steep sections or climbing stairs, so that the meter box 104 is always in a horizontal state, ensuring that the meter box 104 is stably transported by the device.

[0039] Example 2

[0040] Reference Figures 1 to 13 , which is the second embodiment of the present invention, which is different from the first embodiment in that: it also includes a support member 201 including a fixed shaft 201b fixed in the bottom groove of the support plate 201a, a sliding rod 201d sliding in the bottom groove of the support plate 201a, a first support rod 201c rotating on the outer ring of the fixed shaft 201b, and a second support rod 201e rotating on the outer ring of the sliding rod 201d, the first support rod 201c and the second support rod 201e are hinged by a connecting shaft 201f.

[0041] Furthermore, the support member 201 also includes a support shell 201g, two lifting motors 201h symmetrically installed in the support shell 201g, a drive shaft 201i fixed to the output end of the lifting motor 201h, a support block 201j fixed to the inner bottom wall of the support shell 201g, and a slider 201k sliding in the support shell 201g, the support plate 201a slides on the inner side of the support shell 201g, the drive shaft 201i is rotatably connected to the support block 201j, the drive shaft 201i is rotatably connected to the slider 201k through a thread, the support block 201j and the end of the second support rod 201e are hinged, and the slider 201k and the end of the first support rod 201c are hinged.

[0042] The support plate 201a is used to support the tray 101. The fixed axis 201b and the sliding rod 201d in the bottom groove of the support plate 201a and the second support rod 201e and the first support rod 201c respectively hinged to the two provide conditions for the support plate 201a to rise. The lifting motor 201h drives the sliding block 201k to move through the driving shaft 201i, thereby realizing the up and down movement control of the support plate 201a by the support member 201.

[0043] In the bottom groove of the support plate 201a, the fixed shaft 201b is fixed at one end of the groove, providing a basis for rotational support for the second support rod 201e. The sliding rod 201d slides horizontally in the groove along the sliding grooves on both sides of the groove, and when sliding, the sliding grooves will give the sliding rod 201d sufficient space and support to facilitate the stable sliding of the sliding rod 201d.

[0044] The purpose of the lifting motor 201h driving the driving shaft 201i to rotate is to realize the movement of the slider 201k, thereby achieving the lifting and lowering of the support plate 201a. The lifting motor 201h and the driving shaft 201i can also use cylinders or electric slide rails to drive the slider 201k to move to ensure the normal operation of the device. The support shell 201g provides a load-bearing function for the device.

[0045] Specifically, the clamping member 202 includes a protective shell 202a fixed to the top of the support plate 201a, and a positioning column 202b, a sleeve 202c and a return spring 202e arranged between the protective shell 202a and the extrusion frame 202d, the extrusion frame 202d is arranged on the inner side of the protective shell 202a, the positioning column 202b is fixed to the inner wall of the protective shell 202a, the sleeve 202c slides on the surface of the positioning column 202b, one end of the sleeve 202c is fixed to one side of the extrusion frame 202d, and both ends of the return spring 202e are respectively fixed to the inner wall of the positioning column 202b and one side of the extrusion frame 202d.

[0046] Furthermore, the bottom of the extrusion frame 202d is fixedly connected to a push plate 202f on one side facing the protective shell 202a, the outer ring of the slide rod 201d is rotatably connected to a drive block 202g, the top of the drive block 202g is fixedly connected to a drive rod 202h that passes through the support plate 201a, the drive rod 202h is slidably matched with the push plate 202d, and the drive block 202g is slidably matched with the groove at the bottom of the support plate 201a.

[0047] The setting of the protective shell 202a can support the extrusion frame 202d through the setting of the positioning column 202b, the sliding sleeve 202c and the return spring 202e, ensuring that the extrusion frame 202d can remain stable during movement. At the same time, through the setting of the return spring 202e, when the extrusion frame 202d contacts and squeezes the meter box 104, the extrusion force on the meter box 104 can be increased to make it more stable.

[0048] The driving block 202g and the slide rod 201d slide synchronously in the bottom groove of the support plate 201a and support the support plate. The driving rod 202h passes through the support plate 201a and slides in the through groove on one side of the bottom groove of the support plate 201a. One end of the driving rod 202h passes through the support plate 201a and fits against the outer side of the push plate 201f located above the support plate 201a, so that when the first support rod 201c in the support member 201 moves, the driving block 202g and the driving rod 202h can be driven to move through the slide rod 201d, and the push plate 202f is pushed by the driving rod 202h, so that the extrusion frame 202d moves, thereby clamping the meter box 104.

[0049] Specifically, the positioning member 203 includes a support shaft 203a fixed in a groove at the top of the support plate 201a, a rotating disk 203b rotating on the outer ring of the support shaft 203a, and an extrusion rod 203c and a baffle rod 203d fixed on the outer ring of the rotating disk 203b. A torsion spring is arranged between the support shaft 203a and the rotating disk 203b, and the extrusion rod 203c and the baffle rod 203d are arranged at 90 degrees.

[0050] Furthermore, the positioning member 203 also includes a positioning rod 203e sliding inside the support plate 201a, a plug column 203f fixed to the end of the positioning rod 203e, a compression spring 203g arranged below the positioning rod 203e, and a push column 203h fixed to the top of the positioning rod 203e, the two ends of the compression spring 203g are respectively fixed to one side of the positioning rod 203e and the inner wall of the support plate 201a, a positioning groove U is opened on the surface of the rotating disk 203b, and the push column 203h is adapted to the notch on the push plate 202f.

[0051] The support shaft 203a is used to limit the rotating disk 203b. The extrusion rod 203c and the baffle rod 203d are both connected to the rotating disk 203b and connected at the same place of the rotating disk 203b. The angle between the extrusion rod 203c and the baffle rod 203d is 90 degrees. At the same time, the arc groove left on the top of the support plate 201a can ensure sufficient rotation space when the baffle rod 203d rotates around the support shaft 203a, so that the various components of the positioning member 203 can cooperate normally.

[0052] With the arrangement of the positioning rod 203e, the plug 203f, the compression spring 203g and the push pin 203h, the plug 203f can be inserted into the positioning slot U to limit the rotating disk 203b. At this time, the tray 101 can be limited by the shift rod 203d so that it can be stably placed above the support plate 201a.

[0053] The setting of the push column 203h can correspond to the notch on the push plate 202f corresponding to its position. When the driving rod 202h drives the push plate 202f to move, the notch on the push plate 202f slowly covers the push column 203h. When the push column 203h passes through the notch and contacts the push plate 202f, the push plate 202f drives the push column 203h to move. At this time, the positioning rod 203e and the plug column 203f also move synchronously. When the push plate 202f no longer moves, the plug column 203f is inserted into the positioning groove U to limit the rotating disk 203b.

[0054] In the initial position, the push column 203h is located at the notch of the extrusion frame 202d. When the push plate 202f moves until the plug column 203f is inserted into the positioning groove U, the width of the push plate 202d is the same as the distance the push column 203h moves in the notch plus the distance the push column 203h moves, so that the push plate 202d will not be affected by the push column 203h when it moves, and the plug column 203f can be just inserted into the positioning groove U to ensure the normal operation of the device.

[0055] Specifically, the movable part 204 includes a wheel frame 204a fixed to the bottom of the supporting shell 201g, a rotating column 204b fixed to one side of the wheel frame 204a, a supporting wheel 204c rotating on the outer ring of the rotating column 204b, an adjusting frame 204d rotating on the outer ring of the rotating column 204b, a supporting frame 204e fixed to one side of the supporting shell 201g, a track 204f arranged on the surface of the supporting wheel 204c, a fixed plate 204g fixed to the bottom of the supporting shell 201g, a rotating shaft 204h rotating in the fixed plate 204g, a driving wheel 204i fixed to the outer ring of the rotating shaft 204h, and a driving motor 204j fixed to one side of the supporting shell 201g, and the rotating shaft 204h is fixed to the output end of the driving motor 204j.

[0056] Furthermore, a fixed rod 204k is fixedly installed in the internal cavity of one side of the support shell 201b, the outer ring of the fixed rod 204k is rotatably connected to the cylinder 204l, the output end of the cylinder 204l is fixedly connected to the rotating rod 204m, and the rotating rod 204m is rotatably connected to the adjustment frame 204d.

[0057] The wheel frame assembly 204a is configured to provide a stable support for the rotating column 204b, and the rotating column 204b further supports the supporting wheel 204c to ensure its stable operation. The function of the adjustment frame 204d is to provide a supporting platform for multiple rotating columns 204b, thereby realizing the supporting function for multiple supporting wheels 204c to maintain the stability and reliability of the system.

[0058] The support frame 204e is located at the front end of the transport trolley, and is intended to facilitate the movement of the transport trolley toward the stairs. Inside the support frame 204e, there are multiple rotating columns 204b and supporting wheels 204c, which together provide necessary support for the track 204f.

[0059] The function of the fixed plate 204g is to provide stable support for the rotating shaft 204h to ensure its stability during operation. The driving motor 204j is responsible for driving the rotating shaft 204h, and then driving the driving wheel 204i to rotate. The rotation of the driving wheel 204i directly drives the track 204f to move, and finally the track 204f drives the forward movement of the entire transport cart, ensuring the efficient movement of the transport cart on different terrains.

[0060] The cylinder 2041 can push the adjustment frame 204d, so that the angle between the adjustment frame 204d and the support shell 201g changes, which can adapt to the inclination angle of the transport trolley climbing the stairs, keep the transported meter box 104 level, and ensure that the meter box 104 will not slip during transportation.

[0061] After the adjustment frame 204d rotates, the horizontal plate on the support frame 204e connected to the support shell 201g is retractable and rotatable, which can ensure the normal rotation of the adjustment frame 204d and the normal operation of the device.

[0062] During use, when the meter box 104 needs to be transported, the pallet 101 can be placed on the transport platform. At this time, the meter box 104 is stacked on the top of the pallet 101, and the transport trolley is moved to move the support plate 201a to the bottom of the pallet 101. During this process, the support leg 102 is pushed in through the through grooves on both sides of the support plate 201a, and the extrusion rod 203c is squeezed, thereby driving the rotating disk 203b to rotate, so that the torsion spring between the rotating disk 203b and the support shaft 203a is energized.

[0063] When the support plate 201a moves to the specified position, the lifting motor 201h is started by controlling the armrest 205. The lifting motor 201h can drive the driving shaft 201i to rotate, so that the driving shaft 201i drives the sliding block 201k to move, and the sliding block 201k approaches the support block 201j, thereby driving the first support rod 201c and the second support rod 201e to rotate, and the support plate 201a can be pushed up. At this time, the support plate 201a lifts the tray 101. During the movement of the second support rod 201e, the sliding rod 201d can drive the driving block 202g to move, and then drive the driving rod 202h to move, so that the driving rod 202h squeezes the pushing plate 202f, thereby pushing The movable extrusion frame 202d approaches the meter box 104, thereby clamping the stacked meter boxes 104; during the movement of the push plate 202f, the push column 203h first moves in the gap between the push plate 202f and the extrusion frame 202d. After moving for a period of time, the push plate 202f contacts the push column 203h and pushes the push column 203h to move. The push column 203h pushes the positioning rod 203e, so that the positioning rod 203e drives the plug column 203f to be inserted into the positioning groove U, thereby fixing the rotating disk 203b, thereby fixing the blocking rod 203d, so that the blocking rod 203d can effectively block the support leg 102 to prevent the tray 101 from sliding off the support plate 201a.

[0064] When carrying out transportation, the support frame 204e is located on one side of the stairs. At this time, the driving motor 204j can be started to drive the rotating shaft 204h to rotate. The rotating shaft 204h is used to drive the driving wheel 204i to rotate, so that the driving wheel 204i can drive the crawler 204f to move, and the crawler 204f drives the transport trolley to move. When it is necessary to climb the stairs, the crawler 204f on the surface of the support frame 204e first contacts the stairs, thereby driving the trolley to climb the stairs. In this process, the cylinder 204l is started. When the output end of the cylinder 204l is extended, the adjusting frame 204d can be pushed, so that the angle between the adjusting frame 204d and the supporting shell 201g changes, so as to adapt to the inclination angle of the transport trolley when climbing the stairs, and the horizontal plate on the support frame 204e connected to the supporting shell 201g shrinks and rotates, which not only can play a supporting effect, but also will not affect the operation of the device.

[0065] Example 3

[0066] Reference Figure 1-2, which is the third embodiment of the present invention, and is based on the previous two embodiments. This embodiment provides a supporting device, which includes a main body component 100, including a tray 101, support legs 102 and a bearing block 103 fixed to the bottom of the tray 101, and a meter box 104, the meter box 104 is stacked on the top of the tray 101, the tray 101 is placed above the support plate 201a, the support legs 102 and the bearing block 103 are respectively adapted to the through grooves on both sides and the through groove in the middle of the support plate 201a, and the support legs 102 cooperate with the extrusion rod 203c and the blocking rod 203d.

[0067] When in use, the support legs 102 and the supporting blocks 103 can support the pallet 101, so that the support plate 201a can be moved to the bottom of the pallet 101 during transportation, which is convenient for transporting multiple meter boxes 104.
