Description

Technical Field

[0001] This application relates to the field of current collector technology, and in particular to a sliding contact line current collector structure and overhead crane system. Background Technology

[0002] A sliding contact line is a device used to ensure that a mobile device maintains conductive contact during movement. It is generally used in conjunction with a current collector that moves with the mobile device. The current collector generally includes a slider for maintaining contact with the sliding contact line and its matching fixed bracket. During the movement of the mobile device, it is necessary to ensure that the slider and the sliding contact line are in close contact.

[0003] However, during long-term operation, factors such as impact, vibration, or loose connections can easily cause the fixed support of the slider to tilt at various angles, which may cause the slider to detach from the sliding contact line during operation, thus affecting the normal operation of the overhead crane. Utility Model Content

[0004] This application provides a sliding contact line current collector structure and an overhead crane system to reduce the probability of the slider detaching from the sliding contact line, thereby improving the reliability of the power supply of the sliding contact line current collector structure and ensuring the normal operation of the overhead crane.

[0005] The specific technical solution is as follows:

[0006] In a first aspect, embodiments of this application propose a sliding contact line current collector structure, including at least one sliding contact line current collector. The sliding contact line current collector includes a connecting part, at least one bracket assembly, a mounting part, and a slider. The connecting part is used to connect with an overhead crane, and the connecting part includes at least one fixed post. The bracket assembly, the mounting part, the slider, and the fixed post are arranged one-to-one. One end of each bracket assembly is connected to the fixed post, and the other end is connected to the mounting part. Each slider is mounted on the mounting part and is used to connect with the sliding contact line to supply power to the overhead crane. The sliding contact line current collector also includes at least one limiting member arranged one-to-one with the fixed post. The limiting member is used to connect with the overhead crane and is located on the side of the connecting part near the bracket assembly. The limiting member is provided with a limiting groove, and at least a portion of each bracket assembly is located within the limiting groove.

[0007] In this application, the fixed column is connected to the mounting part via a bracket assembly, the slider is mounted on the mounting part, and the connecting part and the limiting member are spaced apart and mounted on the overhead crane. At this time, the sliding contact line can supply power to the overhead crane through the sliding contact line current collector. When the sliding contact line current collector and the overhead crane move relative to the sliding contact line, since at least a portion of the bracket assembly is located within the limiting groove of the limiting member, the limiting groove can support and limit the bracket assembly. The bracket assembly will not shift in the width direction of the limiting groove, nor will it shift towards the bottom wall of the limiting groove. This helps reduce the probability of the slider detaching from the sliding contact line, thereby improving the reliability of the power supply from the sliding contact line current collector structure and ensuring the normal operation of the overhead crane.

[0008] In some embodiments, the number of sliding contact line current collectors is two.

[0009] In some embodiments, the number of the fixing column, the bracket assembly, the mounting part, the slider, and the limiting member is one.

[0010] In some embodiments, the number of the fixing column, the bracket assembly, the mounting part, the slider, and the limiting member are all three.

[0011] In some embodiments, the bracket assembly includes a first link and a second link arranged in parallel, and the lower surface of the mounting portion is higher than the upper surface of the fixing column;

[0012] At least a portion of the first link and / or the second link is located within the limiting groove.

[0013] In some embodiments, the support assembly further includes a first elastic element disposed between the first link and the second link.

[0014] In some embodiments, the mounting portion includes a first connecting block and a mounting head. The first connecting block is connected to the bracket assembly, one end of the mounting head is connected to the first connecting block, and the other end is provided with a mounting groove for fixing the slider.

[0015] In some embodiments, the mounting head is movably inserted into the first connecting block, and the mounting portion further includes a second elastic member disposed between the mounting head and the first connecting block.

[0016] In some embodiments, the connecting portion includes a base plate and a second connecting block. The base plate is used to connect with the overhead crane, the fixing column is disposed on the base plate, the second connecting block is connected to the fixing column, and the bracket assembly is connected to the second connecting block.

[0017] Secondly, embodiments of this application propose an overhead crane system, including an overhead crane, a sliding contact line, and the sliding contact line current collector structure described in the first aspect. The slider is connected to the sliding contact line, and the connecting part and the limiting member are both connected to the overhead crane. The limiting member is located on the side of the connecting part near the support assembly. Attached Figure Description

[0031] Firstly, embodiments of this application propose a sliding contact wire current collector structure 10. For example... Figure 1 and Figure 2 As shown, the sliding contact line current collector structure 10 includes at least one sliding contact line current collector 100. The sliding contact line current collector 100 includes a connecting part 110, at least one bracket assembly 120, at least one mounting part 130, and at least one slider 140. The connecting part 110 is used to connect with the overhead crane 200. The connecting part 110 includes at least one fixed post 111. The bracket assembly 120, the mounting part 130, and the slider 140 are arranged in a one-to-one correspondence with the fixed post 111. One end of each bracket assembly 120 is connected to the fixed post 111, and the other end is connected to the mounting part 130. Each slider 140 is mounted on the mounting part 130 and is used to connect with the sliding contact line 300 to supply power to the overhead crane 200. The sliding contact line current collector 100 also includes at least one limiting member 150 corresponding to the fixed column 111. The limiting member 150 is used to connect with the overhead crane 200 and is located on the side of the connecting part 110 near the support assembly 120. The limiting member 150 is provided with a limiting groove 151, and at least a portion of each support assembly 120 is located in the limiting groove 151.

[0032] In this application, the sliding contact line current collector structure 10 includes at least one sliding contact line current collector 100. The sliding contact line current collector 100 includes a connecting portion 110, at least one support assembly 120, at least one mounting portion 130, and at least one slider 140. "At least one" means that the number of the above components can be one, two, or more. The connecting portion 110 is used for fixed connection with the overhead crane 200; for example, the connecting portion 110 can be fixedly installed on the guardrail of the overhead crane 200.

[0033] The connecting part 110 includes at least one fixing post 111. The fixing posts 111, the bracket assembly 120, the mounting part 130, and the slider 140 are arranged in a one-to-one correspondence. The number of fixing posts 111 determines the number of bracket assemblies 120, mounting parts 130, and sliders 140, while the number of sliding contact lines 300 determines the number of fixing posts 111. That is, as... Figure 1 As shown, when there is only one sliding contact line 300, there is also only one fixed post 111, one bracket assembly 120, one mounting part 130, and one slider 140. The slider 140 can slide on one sliding contact line 300. Or, as... Figure 2 As shown, when there are multiple sliding contact lines 300, there are also multiple and identical fixed posts 111, bracket assemblies 120, mounting parts 130, and sliders 140. Each slider 140 is connected to one sliding contact line 300, so that multiple sliders 140 can slide on multiple sliding contact lines 300 simultaneously.

[0034] Furthermore, one end of each bracket assembly 120 is connected to the fixed column 111, and the other end is connected to the mounting part 130, with each slider 140 mounted on the mounting part 130. Thus, when the slider 140 contacts the sliding contact line 300, the sliding contact line 300 can supply power to the overhead crane 200 through the sliding contact line current collector 100.

[0035] It should be noted that, in Figure 2 In order to make the accompanying drawings easier to observe, only a plurality of sliding contact lines 300, a plurality of corresponding fixed posts 111, a bracket assembly 120 connected to one of the fixed posts 111, a mounting part 130 and a slider 140 are shown as examples, while the plurality of bracket assemblies 120, a plurality of mounting parts 130 and a plurality of sliders 140 connected to the remaining plurality of fixed posts 111 are omitted.

[0036] Furthermore, such as Figure 1 and Figure 2As shown, the sliding contact line current collector 100 of this application also includes at least one limiting member 150 corresponding to the fixed column 111. The limiting member 150 is also used to connect with the overhead crane 200, and the limiting member 150 is located on the side of the connecting portion 110 near the support assembly 120. Optionally, the limiting member 150 and the connecting portion 110 can be installed at intervals on the same part of the overhead crane 200, which is beneficial to improving the convenience of arranging the sliding contact line current collector 100. After the limiting member 150 is arranged, at least a portion of the support assembly 120 is located in the limiting groove 151 of the limiting member 150.

[0037] It should be noted that, in Figure 2 In order to make the accompanying drawings easier to observe, only one limiting member 150 is shown as an example, while the multiple limiting members 150 that limit the remaining multiple bracket assemblies 120 are omitted.

[0038] In this application, the fixed column 111 is connected to the mounting part 130 via the bracket assembly 120, the slider 140 is mounted on the mounting part 130, and the connecting part 110 and the limiting member 150 are spaced apart and mounted on the overhead crane 200. At this time, the sliding contact line 300 can supply power to the overhead crane 200 through the sliding contact line current collector 100. When the sliding contact line current collector 100 and the overhead crane 200 move relative to the sliding contact line 300, since at least a portion of the bracket assembly 120 is located within the limiting groove 151 of the limiting member 150, the limiting groove 151 can support and limit the bracket assembly 120. The bracket assembly 120 will not deviate in the width direction of the limiting groove 151, nor will it deviate towards the bottom wall of the limiting groove 151. This helps reduce the probability of the slider 140 detaching from the sliding contact line 300, thereby improving the reliability of the power supply from the sliding contact line current collector structure 10 and ensuring the normal operation of the overhead crane 200.

[0039] In some embodiments, such as Figure 1 and Figure 2 As shown, there are two sliding contact line current collectors 100. This means that each overhead crane 200 can be powered from both sides by two sliding contact line current collectors 100. This improves the stability of the power supply to the sliding contact line current collector structure 10, thereby further enhancing the reliability of the overhead crane 200.

[0040] In some embodiments, such as Figure 1 As shown, the number of fixed column 111, bracket assembly 120, mounting part 130, slider 140, and limiting member 150 is one each. At this time, the structure of the sliding contact line current collector 100 is relatively simple. The sliding contact line current collector 100 provides power to the overhead crane 200 through a single sliding contact line 300, which helps to improve the convenience of building the power supply system for the overhead crane 200.

[0041] In some embodiments, such as Figure 2 As shown, there are three fixed posts 111, three bracket assemblies 120, three mounting parts 130, three sliders 140, and three limiting members 150. In this configuration, multiple fixed posts 111 are spaced apart, and each bracket assembly 120 is connected to one fixed post 111 and one mounting part 130 at each end. A slider 140 is mounted on each mounting part 130. In other words, the sliding contact line current collector 100 supplies power to the overhead crane 200 through three spaced-apart sliding contact lines 300, thereby improving the reliability and power supply capacity of the overhead crane 200 power supply system.

[0042] In some embodiments, such as Figure 1 As shown, the bracket assembly 120 includes a first connecting rod 121 and a second connecting rod 122 arranged in parallel, and the lower surface of the mounting portion 130 is higher than the upper surface of the fixing post 111. At least a portion of the first connecting rod 121 and / or the second connecting rod 122 is located within the limiting groove 151.

[0043] In this embodiment, the support assembly 120 consists of two parallel connecting rods, a first connecting rod 121 and a second connecting rod 122. This improves the strength of the support assembly 120 and the reliability of the connection between the fixing post 111 and the mounting part 130. Furthermore, the lower surface of the mounting part 130 is higher than the upper surface of the fixing post 111; that is, the first connecting rod 121 and the second connecting rod 122 of the support assembly 120 are inclined, so that the fixing post 111 and the mounting part 130 are not exactly in the same horizontal position. This increases the vertical dimension of the sliding contact line current collector 100, thereby improving the ease of connection between the sliding contact line current collector 100 and the sliding contact line 300.

[0044] It should be noted that "at least a portion of the first link 121 and / or the second link 122 is located within the limiting groove 151" means that at least a portion of both the first link 121 and the second link 122 is located within the limiting groove 151, that is, the limiting groove 151 is deep enough to limit the movement of both the first link 121 and the second link 122. Alternatively, at least a portion of one of the first link 121 and the second link 122 is located within the limiting groove 151, in which case the limiting groove 151 can limit the movement of either the first link 121 or the second link 122.

[0045] In some embodiments, such as Figure 1As shown, the support assembly 120 also includes a first elastic element 123 disposed between the first link 121 and the second link 122. The first elastic element 123 can be, for example, a tension spring. By providing the first elastic element 123, the buffering performance of the support assembly 120 can be improved. On the other hand, the elastic force of the first elastic element 123 can further reduce the probability of the first link 121 and the second link 122 shifting, thereby preventing the slider 140 from detaching from the sliding contact line 300.

[0046] In some embodiments, such as Figure 1 and Figure 3 As shown, the mounting part 130 includes a first connecting block 131 and a mounting head 132. The first connecting block 131 is connected to the bracket assembly 120. One end of the mounting head 132 is connected to the first connecting block 131, and the other end is provided with a mounting groove 1321 for fixing the slider 140.

[0047] This embodiment presents one specific structure of the mounting part 130. The mounting part 130 includes a first connecting block 131 and a mounting head 132. The first connecting block 131 serves to fix the mounting bracket assembly 120 and also serves to connect the mounting head 132. The other end of the mounting head 132 is provided with a mounting groove 1321, which can serve to mount the slider 140.

[0048] Furthermore, such as Figure 1 and Figure 3 As shown, the mounting head 132 is movably inserted into the first connecting block 131, and the mounting portion 130 also includes a second elastic member 133 disposed between the mounting head 132 and the first connecting block 131. This arrangement allows for movement between the mounting head 132 and the first connecting block 131, and consequently, between the slider 140 and the first connecting block 131. Furthermore, under the elastic force of the second elastic member 133, the slider 140 can maintain close contact with the sliding contact line 300 at all times, thereby improving the reliability of the power supply to the sliding contact line current collector structure 10. Optionally, the second elastic member 133 can be, for example, a compression spring, a rubber body, etc.

[0049] It should be noted that there are several ways in which the mounting head 132 can be movably inserted into the first connecting block 131. For example, as... Figure 3 As shown, one end of the mounting head 132 is a pin, and the first connecting block 131 is provided with a through hole. After the pin passes through the through hole, it is locked with the nut 134. This application does not limit this.

[0050] In some embodiments, such as Figure 1As shown, the connecting part 110 includes a base plate 112 and a second connecting block 113. The base plate 112 is used to connect with the overhead crane 200. The fixing column 111 is disposed on the base plate 112. The second connecting block 113 is connected to the fixing column 111. The bracket assembly 120 is connected to the second connecting block 113.

[0051] This embodiment presents one specific structure of the connecting part 110. The connecting part 110 includes a base plate 112, at least one fixing post 111 disposed on the base plate 112, and a second connecting block 113 connected to the fixing post 111. The base plate 112 serves to connect the sliding contact line current collector 100 and the overhead crane 200, while the second connecting block 113 serves to connect to the support assembly 120. The second connecting block 113 allows for an indirect connection between the connecting part 110 and the support assembly 120, thereby improving the convenience of their connection.

[0052] Secondly, this application provides an overhead crane system 1. The overhead crane system 1 includes an overhead crane 200, a sliding contact line 300, and the sliding contact line current collector structure 10 described in the first aspect. A slider 140 is connected to the sliding contact line 300, and a connecting part 110 and a limiting member 150 are both connected to the overhead crane 200. The limiting member 150 is located on the side of the connecting part 110 near the support assembly 120.

[0053] The overhead crane system 1 of this application embodiment uses the sliding contact line current collector structure 10 described in the first aspect to power the overhead crane 200. When the sliding contact line current collector 100 and the overhead crane 200 move relative to the sliding contact line 300, since at least a portion of the support assembly 120 is located within the limiting groove 151 of the limiting member 150, the limiting groove 151 can support and limit the support assembly 120. The support assembly 120 will not deviate in the width direction of the limiting groove 151, nor will it deviate towards the bottom wall of the limiting groove 151. This helps to reduce the probability of the slider 140 detaching from the sliding contact line 300, thereby improving the reliability of the power supply from the sliding contact line current collector structure 10 and ensuring the normal operation of the overhead crane 200.

[0054] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
