Description

Technical Field

[0001] The invention relates to the technical field of power supply equipment, and in particular to an annular busbar device and a quay bridge with an annular beam. Background Art

[0002] The busbar power supply system, also known as the sliding contact line or busbar power supply, is an electrical system used to provide power to mobile equipment. The busbar is generally composed of power lines, control lines and communication lines. At present, there are many quay cranes using busbar power supply systems in ports. Conventional quay cranes are only equipped with a single trolley, which moves back and forth. Since only a single trolley needs to be powered and communicated, it is easier to power and communicate when using busbar power supply. Therefore, the number of busbars is small, and since the busbar does not interfere with the trolley, the power line, control line and communication line can be arranged in parallel or vertically in sequence. However, in the circular continuous quay crane with a ring beam, multiple (≥3) load-carrying trolleys work at the same time, and the trolleys need to circulate on straight lines and semicircular lines. Since each trolley contains an independently controlled lifting mechanism and a trolley drive mechanism, it is necessary to supply power and communicate to each trolley separately. The current load in the system is large, so it is necessary to increase the number of busbars to supply power and communicate separately. However, on the one hand, if the conventional busbar arrangement is used, the power lines arranged in parallel or vertically in sequence occupy a large space and are difficult to arrange. On the other hand, when the trolley passes through a curve quickly, the power lines, control lines and communication lines arranged parallel or vertically in the busbar are subjected to a greater impact and only one side is subjected to force. The connection between the trolley and the busbar is easily stuck, and the power supply stability and signal stability are low. Summary of the invention

[0003] In view of this, the present invention provides an annular busbar device and a quay bridge with an annular beam, which can reduce occupied space and improve power supply stability and signal transmission stability.

[0004] In order to solve at least one of the above technical problems, the present invention adopts the following technical solutions:

[0039] In order to make the purpose, technical solution and advantages of the embodiment of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0040] First, a ring-shaped busbar device according to an embodiment of the present invention is described in detail below with reference to the accompanying drawings.

[0041] like Figures 1 to 3 As shown, the annular busbar device of the embodiment of the present invention can be used for a quay bridge having an annular beam 100, and the annular busbar device of the embodiment of the present invention can include: a plurality of busbar brackets 200, a control busbar group 300, a power supply busbar group 400, and a carbon brush assembly 500. Among them, a plurality of busbar brackets 200 are arranged at intervals below the annular beam 100, and the plurality of busbar brackets 200 form an annular shape corresponding to the annular beam 100; the control busbar group 300 is correspondingly arranged on a plurality of busbar brackets 200 and is an annular shape corresponding to the annular beam 100; the power supply busbar group 400 is correspondingly arranged on a plurality of busbar brackets 200 and is an annular shape corresponding to the annular beam 100, and the power supply busbar group 400 is located below the control busbar group 300; one end of the carbon brush assembly 500 is respectively electrically connected to the control busbar group 300 and the power supply busbar group 400, and the other end of the carbon brush assembly 500 is used to electrically connect to the trolley 101 on the annular beam 100.

[0042] In this embodiment, the power supply wire group 400 is used to provide current to the multiple trolleys 101 on the annular beam 100, and the control wire group 300 is used to transmit control signals to the multiple trolleys 101 on the annular beam 100 and control the current transmitted by the power supply wire group 400. By arranging multiple busbar brackets 200 below the annular beam 100, and the multiple busbar brackets 200 forming a ring corresponding to the annular beam 100, and then laying the control wire group 300 and the power supply wire group 400 on the multiple busbar brackets 200, respectively, and connecting the carbon brush assembly 500 electrically connected to the multiple trolleys 101 on the annular beam 100 to the control wire group 300 and the power supply wire group 400, it is possible to provide current to the multiple trolleys 101 on the annular beam 100, and control the multiple trolleys 101 respectively, thereby improving the working efficiency of the quay crane. In addition, by setting the power supply wire group 400 below the control wire group 300, compared with setting the power supply wire group 400 and the control wire group 300 side by side, on the one hand, the occupied space can be reduced and the layout difficulty can be reduced. On the other hand, since the power supply wire group 400 is vertically arranged below the control wire group 300, when the trolley 101 passes through the curve quickly, the power supply wire group 400 and the control wire group 300 can jointly bear the lateral force transmitted by the trolley 101 through the carbon brush assembly 500, thereby avoiding excessive wear of the busbar device, and also avoiding the carbon brush assembly 500 from being stuck in the power supply wire group 400 or the control wire group 300, thereby improving the power supply stability and signal transmission stability.

[0043] like Figure 3 As shown, each busbar support 200 includes: a horizontal support 210, a vertical support 220 and a reinforcing rib 230. The horizontal support 210 is arranged below the annular beam 100, and the control sliding wire group 300 is correspondingly arranged on the side of the horizontal support 210 away from the annular beam 100; the vertical support 220 is arranged below the horizontal support 210 and extends in the vertical direction, and the power supply sliding wire group 400 is correspondingly arranged on the vertical support 220 along the length direction of the vertical support 220; one end of the reinforcing rib 230 is connected to the horizontal support 210, and the other end of the reinforcing rib 230 is connected to the vertical support 220.

[0044] In this embodiment, the length direction of the vertical bracket 220 is perpendicular to the plane where the horizontal bracket 210 is located, and one end of the reinforcing rib 230 is connected to the horizontal bracket 210, and the other end of the reinforcing rib 230 is connected to the vertical bracket 220. At this time, the horizontal bracket 210, the vertical bracket 220 and the reinforcing rib 230 form a triangular support. The triangular support has a light weight, and when the trolley 101 passes through a curve quickly, it can bear the large lateral force transmitted by the trolley 101 through the carbon brush assembly 500, thereby effectively improving the power supply stability and signal transmission stability.

[0045] like Figure 3 As shown, the control slide wire group 300 includes a plurality of control slide wires 301 , and the plurality of control slide wires 301 are spaced apart in the horizontal direction to form a plurality of rings corresponding to the ring beam 100 .

[0046] In this embodiment, the multiple control slides 301 in the control slide group 300 are all formed into a ring corresponding to the ring beam 100, and a gap is provided between two adjacent control slides 301. Therefore, by providing a gap between two adjacent control slides 301, a buffer space can be provided for the carbon brush assembly 500 when the trolley 101 passes through a curve quickly, avoiding direct collision between the carbon brush assembly 500 and the control slide 301, thereby avoiding excessive wear of the control slide 301 and increasing the service life of the control slide 301 and the carbon brush assembly 500.

[0047] like Figure 3 As shown, the power supply slide wire group 400 includes a plurality of power supply slide wires 401 arranged in sequence along the vertical direction, and each power supply slide wire 401 is in a ring shape corresponding to the ring beam 100 .

[0048] In this embodiment, when the vehicle 101 passes a curve quickly, multiple power supply slide wires 401 arranged in sequence along the vertical direction can be subjected to force at the same time, so as to bear the larger lateral force transmitted by the carbon brush assembly 500, thereby effectively improving the power supply stability and signal transmission stability.

[0049] like Figure 3 As shown, the carbon brush assembly 500 includes: a transverse carbon brush 510, a longitudinal carbon brush 520 and a carbon brush bracket 530. The transverse carbon brush 510 is arranged in the horizontal direction and is respectively electrically connected to each control slide wire 301 by sliding; the longitudinal carbon brush 520 is arranged in the vertical direction and is respectively electrically connected to each power supply slide wire 401 by sliding; the transverse carbon brush 510 and the longitudinal carbon brush 520 are arranged on the carbon brush bracket 530, and the carbon brush bracket 530 is used to connect with the trolley 101.

[0050] In this embodiment, the longitudinal carbon brush 520 is perpendicular to the transverse carbon brush 510, and the transverse carbon brush 510 is respectively connected to each control slide line 301 in a sliding electrical connection, and the longitudinal carbon brush 520 is respectively connected to each power supply slide line 401 in a sliding connection. The transverse carbon brush 510 and the longitudinal carbon brush 520 always move synchronously, thereby further improving the power supply stability and signal transmission stability.

[0051] In one embodiment of the present invention, the carbon brush bracket 530 includes: a transverse carbon brush bracket (not shown) and a longitudinal carbon brush bracket (not shown). The transverse carbon brush bracket is arranged in the horizontal direction, and one end of the transverse carbon brush bracket is connected to the transverse carbon brush 510, and the other end of the transverse carbon brush bracket is connected to the trolley 101; the longitudinal carbon brush bracket is arranged below the transverse carbon brush bracket in the vertical direction and connected to the transverse carbon brush bracket, one end of the longitudinal carbon brush bracket is connected to the longitudinal carbon brush 520, and the other end of the longitudinal carbon brush bracket is connected to the trolley 101. By separately arranging the transverse carbon brush bracket and the longitudinal carbon brush bracket, and supporting the transverse carbon brush 510 and the longitudinal carbon brush 520 respectively, the structural strength can be effectively improved, and when the trolley 101 passes through a curve quickly, the damage of the transverse carbon brush 510 and the longitudinal carbon brush 520 can be avoided, thereby improving the service life.

[0052] like Figure 3 As shown, the annular busbar device further includes: a waveguide wire 600, which is correspondingly arranged on a plurality of horizontal supports 210 and located on a side of the control busbar group 300 away from the vertical support 220, and the waveguide wire 600 forms a ring corresponding to the annular beam 100 along the horizontal direction. A waveguide communication interface is arranged on the transverse carbon brush support, and the transverse carbon brush support is electrically connected to the waveguide wire 600 through the waveguide communication interface.

[0053] In this embodiment, the waveguide wire 600 is used to communicate with multiple trolleys 101 on the annular beam 100. By setting the waveguide wire 600 to be formed into a ring corresponding to the annular beam 100, it is possible to communicate with multiple trolleys 101 simultaneously, thereby improving the working efficiency of the quay crane.

[0054] The present invention further provides a quay bridge having an annular beam 100, comprising the annular busbar device described in any one of the above embodiments.

[0055] The annular busbar device of the present invention can reduce the occupied space and reduce the difficulty of layout by vertically arranging the power supply busbar group 400 below the vacant busbar group. On the other hand, since the power supply busbar group 400 is vertically arranged below the control busbar group 300, when the trolley 101 passes through the curve quickly, the power supply busbar group 400 and the control busbar group 300 can be jointly stressed, thereby avoiding excessive wear of the busbar device, so that the trolley 101 located at any position of the annular beam 100 can obtain stable control and power supply, thereby improving the power supply stability and signal transmission stability.

[0056] Unless otherwise defined, the technical terms or scientific terms used in the present invention shall have the usual meanings understood by persons with ordinary skills in the field to which the present invention belongs. The words "first", "second" and similar words used in the present invention do not indicate any order, quantity or importance, but are only used to distinguish different components. Similarly, words such as "one" or "one" do not indicate quantity restrictions, but indicate the existence of at least one.

[0057] The above are preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
