[0048] See Figure 1 and Figure 2 As shown. An embodiment of this application provides a charging device 1, including a charging assembly 11 and a clamping assembly 12. Part of the clamping assembly 12 is connected to the charging assembly 11, and part of the clamping assembly 12 is used to engage with the luffing trolley of a tower crane. The clamping assembly 12 includes a fixing member 121, a sliding member 122, and a connecting member 123. One side of the fixing member 121 is connected to the charging assembly 11. The sliding member 122 is slidably connected to the fixing member 121. The fixing member 121 includes a first clamping clamp 1211, and the sliding member 122 includes a second clamping clamp 1221. The sliding member 122 is used to drive the second clamping clamp 1221 to move towards or away from the first clamping clamp 1211, so that the first clamping clamp 1211 and the second clamping clamp 1221 clamp or release the luffing trolley. When the first clamping clamp 1211 and the second clamping clamp 1221 are in a clamping state, the connecting member 123 connects the fixing member 121 and the sliding member 122.

[0049] Specifically, the clamping assembly 12 serves as the connection structure of the charging device 1, connecting the charging assembly 11 and the luffing trolley of the tower crane, thereby achieving the connection between the charging assembly 11 and the luffing trolley. The charging assembly 11 serves as the power supply structure of the charging device 1, connecting the tower crane's video camera and other structures to charge the video camera and other structures, ensuring the normal operation of the video camera.

[0050] It should be noted that the clamping component 12 in this application can also be connected to other structures of the tower crane, such as the boom. This application only uses the connection of the clamping component 12 to the luffing trolley as an example for illustration. Similarly, the charging component 11 in this application can also supply power to other electrical components in the tower crane that require charging. This application only uses a video camera as an example for illustration.

[0051] Further, one side of the fixing member 121 is connected to the charging assembly 11. During the process of installing and connecting the charging assembly 11 and the luffing trolley, the first clamping jaw 1211 and the second clamping jaw 1221 are in a state of loosening the luffing trolley. At this time, the connecting member 123 is not connected between the fixing member 121 and the sliding member 122, and the sliding member 122 can slide relative to the fixing member 121. The second clamping jaw 1221 is driven by the sliding member 122 to move towards the first clamping jaw 1211, so as to clamp the luffing trolley by the first clamping jaw 1211 and the second clamping jaw 1221. It can be understood that, when the first clamping jaw 1211 and the second clamping jaw 1221 are in the process of clamping the luffing trolley, the connecting member 123 is connected between the fixing member 121 and the sliding member 122, so as to realize the fixed connection between the clamping assembly 12 and the luffing trolley, and finally realize the installation and connection between the charging assembly 11 and the luffing trolley.

[0052] Since, during the process of fixing the clamping assembly 12 and the luffing trolley, only the sliding member 122 needs to slide relative to the fixing member 121, so as to drive the second clamping jaw 1221 to move towards the first clamping jaw 1211, thereby realizing the clamping and fixing of the luffing trolley. It can be understood that, during the process of clamping and fixing the luffing trolley by the first clamping jaw 1211 and the second clamping jaw 1221, it is not limited to a specific size of the luffing trolley. Only the size of the luffing trolley needs to be smaller than the maximum clamping distance between the first clamping jaw 1211 and the second clamping jaw 1221, that is, different size types of luffing trolleys can be clamped, so as to realize the installation of the charging assembly 11 with different size types of luffing trolleys, and the installation of the charging assembly 11 can be facilitated.

[0053] In addition, since the clamping assembly 12 can realize the installation of the charging assembly 11 with different size types of luffing trolleys, the applicability of the clamping assembly 12 can be improved, the clamping assembly 12 can be unified, and the unification and manufacturing of the clamping device can be facilitated.

[0054] In addition, it should be noted that, if the charging assembly 11 is installed on the lifting arm of the tower crane, since the lifting arm will hoist the winch during lifting, causing oil splashing, which will cause the charging assembly 11 to rust and affect the charging function. Since the clamping assembly 12 can realize the installation of the charging assembly 11 with the luffing trolley, the charging assembly 11 can not be installed on the lifting arm of the tower crane, the pollution of the charging assembly 11 by oil can be avoided, and the service life of the charging assembly 11 can be improved.

[0055] Meanwhile, since the application only needs to control the sliding movement of the sliding member 122 relative to the fixed member 121, i.e. the clamping of the clamping assembly 12 and the amplitude car can be achieved by the clamping of the second clamping jaw 1221 relative to the first clamping jaw 1211, only one operator can complete the entire installation process, on the one hand, which can reduce the operation difficulty of the operator; on the other hand, it can reduce the danger of the operator operating in the air.

[0056] In some embodiments, referring to Figures 1-5 As shown, the fixed member 121 further comprises a fixed body 1212, one side of the fixed body 1212 is fixedly connected to the charging assembly 11, and the first clamping jaw 1211 is arranged on the side of the fixed body 1212 away from the charging assembly 11; the sliding member 122 further comprises a sliding body 1222, and the second clamping jaw 1221 is arranged on the side of the sliding body 1222 away from the charging assembly 11; when the first clamping jaw 1211 and the second clamping jaw 1221 are in the clamping state, the connecting member 123 is arranged through the fixed body 1212 and connected to the sliding body 1222, and the sliding body 1222 is used to drive the second clamping jaw 1221 to move towards or away from the first clamping jaw 1211.

[0057] In this way, the fixed body 1212 can provide support and fixation for the first clamping jaw 1211, and the sliding body 1222 can provide support and fixation for the second clamping jaw 1221, on the one hand, during the clamping or releasing of the amplitude car by the first clamping jaw 1211 and the second clamping jaw 1221, the relative movement of the sliding body 1222 and the fixed body 1212 can be achieved, thereby facilitating the control of the movement of the first clamping jaw 1211 and the second clamping jaw 1221, thereby facilitating the operator's operation control of the clamping assembly 12. Meanwhile, the amplitude car can be clamped by the first clamping jaw 1211 and the second clamping jaw 1221, and the charging assembly 11 can be connected by the fixed body 1212, thereby facilitating the connection and installation of the clamping assembly 12, the charging assembly 11 and the amplitude car.

[0058] In some embodiments, the first clamping jaw 1211 and the second clamping jaw 1221 are arranged opposite to each other along the sliding direction of the sliding body 1222 and the fixed body 1212; the side of the first clamping jaw 1211 facing the second clamping jaw 1221 is provided with a first engagement part, and / or the side of the second clamping jaw 1221 facing the first clamping jaw 1211 is provided with a second engagement part.

[0059] Thus, in the process that the first clamping jaw 1211 and the second clamping jaw 1221 clamp the luffing trolley, the first clamping jaw 1211 and the second clamping jaw 1221 can improve the connection tightness between the first clamping jaw 1211 and the second clamping jaw 1221 and the luffing trolley through the first engagement part and the second engagement part, so that the stability and reliability of the mounting connection between the clamping assembly 12 and the luffing trolley can be improved, so that the clamping assembly 12 and the luffing trolley can be prevented from falling off.

[0060] In some embodiments, referring to Figure 6 As shown, the fixed body 1212 surrounds to form a first open cavity, and the sliding body 1222 is arranged in the first open cavity.

[0061] Thus, the sliding body 1222 can be arranged in the first open cavity of the fixed body 1212, so that the space occupied by the sliding body 1222 can be reduced, so that the space utilization of the clamping assembly 12 can be improved, and the space occupied by the clamping assembly 12 can be reduced.

[0062] In some embodiments, referring to Figure 6 As shown, the sliding body 1222 is provided with a notch 1223, the notch 1223 penetrates the sliding body 1222 in the direction towards the charging assembly 11; the fixed body 1212 includes at least one protruding part 1213, the protruding part 1213 is fixedly connected to the charging assembly 11; wherein, along the protruding direction of the protruding part 1213, the projection of the protruding part 1213 is located in the projection of the notch 1223.

[0063] Thus, the fixed body 1212 and the charging assembly 11 can be mounted and connected at the position area of the notch 1223 through the protruding part 1213, on the other hand, since the projection of the protruding part 1213 is located in the projection of the notch 1223, so that the protruding part 1213 can be located in the projection of the notch 1223 at all times in the process that the sliding body 1222 slides relative to the fixed body 1212, so that the sliding movement of the sliding body 1222 can be avoided from being interfered by the protruding part 1213, so that the normal sliding movement of the sliding body 1222 can be ensured, and the normal use of the clamping assembly 12 can be ensured.

[0064] In some embodiments, referring to Figure 3 As shown, the fixed body 1212 further includes a recessed part 1214, the recessed part 1214 is arranged on the side of the fixed body 1212 away from the charging assembly 11, and is recessed towards the charging assembly 11 to form the protruding part 1213.

[0065] Thus, the recessed part 1214 can form the protruding part 1213 through stamping, on the one hand, the manufacturing of the protruding part 1213 can be facilitated; on the other hand, additional preparation materials are not needed to be introduced in the process of preparing the protruding part 1213, so that the production cost of the protruding part 1213 in the preparation process can be reduced.

[0066] In some embodiments, referring to Figure 6 As shown in the drawings, one side of the fixed body 1212 is provided with a through hole, one side of the sliding body 1222 is provided with a fixed part 1224, and when the first clamping jaw 1211 and the second clamping jaw 1221 are in the clamping state, the connecting piece 123 is arranged in the through hole and connected to the fixed part 1224.

[0067] In this way, on the one hand, since the connecting piece 123 is only arranged in the through hole, that is, the connecting piece 123 is not fixedly connected with the fixed body 1212, so that the switching of different states of the fixed body 1212 and the sliding body 1222 can be facilitated, so that the clamping or loosening of the fixed body 1212 and the sliding body 1222 can be realized, on the other hand, when the first clamping jaw 1211 and the second clamping jaw 1221 are in the clamping state, the connecting piece 123 is arranged in the through hole and connected to the fixed part 1224, so that the connecting piece 123 can be connected with the fixed body 1212 and the sliding body 1222 by being arranged in the through hole and connected to the fixed part 1224.

[0068] In some embodiments, referring to Figures 2-4 As shown in the drawings, the charging assembly 11 comprises a support 111 and a charging unit 112, the support 111 is connected to the charging unit 112 and the clamping assembly 12; wherein the sliding direction of the fixed part 121 and the sliding part 122 is the same as the extension direction of the charging unit 112.

[0069] In this way, the support 111 can be connected to the charging unit 112 and the clamping assembly 12, so that the support 111 and the charging unit 112 can play different roles, so that the installation connection of the charging assembly 11 and the clamping assembly 12 and the normal power supply of the charging assembly 11 can be ensured. In addition, since the sliding direction of the fixed part 121 and the sliding part 122 is the same as the extension direction of the charging unit 112, so that during the movement of the sliding part 122 relative to the fixed part 121, it is always the same as the extension direction of the charging unit 112, so that the operator can always be in the same direction during installation and operation, so that the operation of the operator can be facilitated.

[0070] In some embodiments, referring to Figures 2-4 As shown in the drawings, the charging unit 112 comprises a charging body 1121 and a bending part 1122, the bending part 1122 is arranged on both sides of the charging body 1121 along the sliding direction of the fixed part 121 and the sliding part 122, and the bending part 1122 is arranged protruding away from the fixed part 121.

[0071] In this way, during the connection process of the charging unit 112 and the video camera, the bending part 1122 can provide a transition for the connection process of the charging unit 112 and the video camera, so as to improve the stability and reliability of the connection of the charging unit 112 and the video camera.

[0072] In some embodiments, the fixing member 121 is an integrally formed structure, and / or the sliding member 122 is an integrally formed structure.

[0073] In this way, on the one hand, the manufacturing process of the fixing member 121 and / or the sliding member 122 can be facilitated, and the manufacturing difficulty of the fixing member 121 and / or the sliding member 122 can be simplified; on the other hand, the strength of the fixing member 121 and / or the sliding member 122 can be improved, and the service life of the clamping assembly 12 can be improved.

[0074] Optionally, along the extension direction of the charging body 1121, the length of the charging body 1121 is greater than the distance between the first clamping jaw 1211 and the second clamping jaw 1221.

[0075] In this way, it can be ensured that the length of the charging body 1121 is always greater than the distance between the first clamping jaw 1211 and the second clamping jaw 1221, so as to ensure that the charging body 1121 can always be connected with the video camera, thereby ensuring that the charging body 1121 can normally charge the video camera.
