DETAILED DESCRIPTION

[0030] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0031] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other. The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions.

[0032] See also Figure 1 to Figure 4 The present application provides a trolley frame 100 that can be used for a current-carrying trolley.

[0033] See also Figure 1 The current-carrying trolley includes: a supporting assembly 10, a frame body 20, a traveling motor 30 and a fixed cantilever 50.

[0034] The frame body 20 is provided with a plurality of running wheels 40. By way of example, three running wheels 40 are used in this embodiment. The number of running wheels 40 is only described by way of example.

[0035] The travel motor 30 is disposed on the frame body 20 and connected to one of the travel wheels 40. The travel motor 30 is used to drive one of the travel wheels 40 to move, and the travel wheel 40 acts as a driving wheel to drive the other travel wheels 40 to move. One end of the fixed cantilever 50 is connected to the frame body 20, and the other end is connected to the travel motor 30. Thus, the travel motor 30 is installed on one side of the trolley body through the fixed cantilever 50.

[0036] The support assembly 10 is pivotally connected to the frame body 20 and is used to be fixedly connected to the vehicle body so that the vehicle body can pivot relative to the frame body 20 .

[0037] The trolley frame 100 of the present application is provided with a support assembly 10, so that the support assembly 10 is pivotally connected to the trolley body and is used to be fixedly connected to the body. When one of the running wheels 40 is installed in the air, the trolley body can adaptively pivot to adjust the position of the running wheel 40, so that each running wheel 40 of the trolley frame 100 can contact the guide rail, and the trolley frame 100 provides a stable and reliable load.

[0038] In one example, see again Figure 1 When the leftmost running wheel 40 of the trolley frame 100 is suspended, the trolley body relatively moderately pivots counterclockwise so that the running wheel 40 can contact the guide rail. In another exemplary embodiment, when the rightmost running wheel 40 of the trolley frame 100 is suspended, the trolley body relatively moderately pivots clockwise so that the running wheel 40 can contact the guide rail.

[0039] In addition, the trolley frame 100 is configured such that the trolley body is fixedly connected to the support assembly 10 and is pivotally connected to the vehicle body to achieve the functions of this embodiment, which is also within the scope of the present application.

[0040] See also Figure 2 The frame body 20 includes two supporting ear plates 22 distributed along the left and right directions of the platform frame 100;

[0041] The support assembly 10 includes: a support frame 11 and a rotating shaft 12 . The support frame 11 and the support ear plate 22 are respectively sleeved on the rotating shaft 12 . The support frame 11 can pivot relative to the support ear plate 22 .

[0042] The support ear plate 22 is a part of the side wall of the frame body 20, and the top wall of the frame body 20 forms an avoidance groove for the support ear plate 22 to pass through. The two support ear plates 22 are along the through-shaft hole of the platform frame 100. The left and right side walls of the support frame 11 are provided with first through-holes 116. The rotating shaft 12 passes through the first through-hole 116 and the through-shaft hole respectively.

[0043] Through the cooperation of the support frame 11 , the rotating shaft 12 and the support ear plate 22 , the support ear plate 22 drives the frame body 20 to pivot relative to the support frame 11 , the structure is simple, and the pivoting is stable and reliable.

[0044] The support assembly 10 further includes a protective cover 13 . The protective cover 13 is disposed on the upper surface of the frame body 20 , and the rotating shaft 12 passes through the protective cover 13 .

[0045] The left and right side walls of the protective cover 13 are both provided with second through holes 132 aligned with the first through holes 116, and the second through holes 132 are used for the rotation shaft 12 to pass through. The protective cover 13 and the upper surface of the frame body 20 together form a receiving cavity, which is connected to the second through holes 132, and the exposed portion of the rotation shaft 12 between the two supporting ear plates 22 is placed in the receiving cavity.

[0046] Since the protective cover 13 is adopted to prevent foreign matter from interfering with the pivoting of the rotating shaft 12, the operation of the rotating shaft 12 is stable and reliable.

[0047] Both ends of the rotating shaft 12 are provided with shaft baffles 14. The cross-sectional area of ​​the shaft baffles 14 is configured to be larger than the end surface area of ​​the rotating shaft 12 to prevent the rotating shaft 12 from falling out from one end during operation, so that the pivoting is more stable.

[0048] A lug 21 is provided on the upper surface of the frame body 20. The lug 21 provides an installation position for the rope suspension to facilitate the transportation of the platform frame 100.

[0049] See also Figure 3 Furthermore, the two side wing plates 112 of the support frame 11 are connected to the top plate 111 and extend downward. The first through hole 116 is formed in the side wing plates 112 .

[0050] The top plate 111 is used to be connected to the chassis of the vehicle body, and the side wing plates 112 and the top plate 111 are arranged perpendicular to each other.

[0051] The top plate 111 of the support frame 11 defines a positioning groove 114 to fit with a positioning protrusion (not shown) on the chassis of the vehicle body.

[0052] When installing the trolley frame 100 , the positioning protrusion of the vehicle chassis is inserted into the positioning groove 114 , so that the installation of the trolley frame 100 can be pre-positioned, the difficulty of assembly is reduced, and the mechanical strength of the installation is enhanced.

[0053] Combination Figure 3 and Figure 4 The front baffle plate 113 of the support frame 11 is recessed to form a notch 115 ; the protective cover 13 is provided with an oil filling hole 131 .

[0054] The notch 115 is configured such that its projection coincides with the oil filling hole 131. That is, the notch 115 serves as a avoidance hole to allow the oil filling hole 131 to be directly exposed, so that the user can inject oil into the oil filling hole 131.

[0055] In one embodiment of the present application, a current-carrying trolley is disclosed, comprising: a trolley body, a power supply device and a pushing device, wherein the power supply device and the pushing device are arranged on the trolley body, and the trolley body comprises any one of the above-mentioned trolley frames 100.

[0056] The current-carrying trolley of this embodiment adopts a trolley frame 100, and the support assembly 10 is arranged so that the support assembly 10 is pivotally connected to the trolley body and is used to be fixedly connected to the trolley body. When one of the running wheels 40 is installed in the air, the trolley body can be adaptively pivoted to adjust the position of the running wheel 40, so that each running wheel 40 of the trolley frame 100 can contact the guide rail, and the trolley frame 100 provides a stable and reliable load. The load stability of the current-carrying trolley is good.

[0057] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom still fall within the scope of protection created by this application.
