Description

Technical Field

[0001] The utility model relates to the technical field of movable power transmission connection, in particular to a telescopic cable device. Background Art

[0002] In the relatively movable connected device, there is a situation where the power supply end and the power consumption end can move relatively and are connected by circuits, such as the reciprocating lifting equipment in the side conveyor line of the WBS system of automobile manufacturing, which includes a lifting device (power supply end) connected to the power supply and a connecting device (power consumption end) connected to the bottom of the lifting device and can be lifted and moved. The lifting device is connected to the power supply, and it is not convenient to connect the connecting device to the power circuit when the connecting device is lifted and moved, so it needs to be connected to the power supply through the lifting device. The common method of circuit connection between the power supply end and the relatively movable power consumption end is to design the length of the transmission cable redundantly, so that it can still be connected to the power supply when the power end and the power supply end move relatively. In this connection method, the transmission cable is not fixed. When the power end and the power supply end move relatively, the transmission cable is prone to swing, damage, or being cut by other devices. When the relative displacement is large, the upper connection part of the transmission cable is under the action of gravity, and the tension is large and it is easy to be worn and broken, which poses a great safety hazard.

[0021] 2. Using the spring as an elastic expansion member makes it convenient to spirally wind the flexible power transmission cable and fix it on the spring, so that the power transmission cable and the spring can be fixed in a spiral structure in a ratio of approximately one to one; when the spring is expanded and contracted, the power transmission cable follows the expansion and contraction, and has a certain anti-roll performance;

[0040] The utility model is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0041] The present application relates to a telescopic cable device 10, which is used for electrically connecting a power supply end and a power consumption end that are relatively movable. An elastic telescopic member is used to fix the power consumption end and the power supply end through a first connecting plate 1 and a second connecting plate 3. The power consumption end and the power supply end can move relatively along the telescopic direction of the elastic telescopic member. A flexible power transmission cable is spirally wound and fixed on the elastic telescopic member, and the power consumption end and the power supply end are respectively connected at both ends. The spirally wound power transmission cable can be telescoped along the elastic telescopic member to realize power supply for the power consumption end equipment, avoiding the connection points at both ends of the power transmission cable being subjected to large tension and accelerated wear under the action of gravity, and solving the problem of safety hazards caused by unfixed transmission cables. The overall structure is simple, easy to use, and has great promotion value.

[0042] A telescopic cable device 10, such as Figures 1 to 4 As shown, it includes a first connecting plate 1, a second connecting plate 3, an elastic telescopic member and a flexible power transmission cable. The first connecting plate 1 and the second connecting plate 3 are used to fix the connection between the power supply end and the power consumption end, and can be connected inverted, that is, the first connecting plate 1 is fixedly connected to the power consumption end, and the second connecting plate 3 is fixedly connected to the power supply end; the two ends of the elastic telescopic member are fixedly connected to the first connecting plate 1 and the second connecting plate 3, and the power consumption end and the power supply end can move relatively; the power transmission cable is spirally wound along the expansion and contraction direction of the elastic telescopic member and fixedly connected to the elastic telescopic member, and the two ends of the power transmission cable are respectively used to connect the power supply end and the power consumption end. When the power consumption end and the power supply end are relatively displaced, the elastic telescopic member expands and contracts, and the power transmission cable is a spiral structure, which has great ductility in the axial direction of the spiral structure, and can move with the elastic telescopic member, which is equivalent to expanding and contracting with the elastic telescopic member. Because it is fixedly connected to the elastic telescopic member, it avoids the situation where the tension at the end of the power transmission cable is large under the action of gravity, and at the same time solves the problem of safety hazards caused by the unfixed power transmission cable.

[0043] In some embodiments, Figure 5 As shown, the first connecting plate 1 and the second connecting plate 3 of the telescopic cable device 10 are respectively bolted to the lifting device 9 (power supply end) and the connecting device 8 (power consumption end) by U-shaped bolts, and the two ends of the transmission cable are respectively connected to the power supply of the lifting device 9 and the connecting device 8 to transmit electrical energy to the connecting device 8.

[0044] like Figure 1 As shown, in some embodiments, a spring 2 is selected as an elastic telescopic member, and the two ends of the spring 2 are respectively fixed to the first connecting plate 1 and the second connecting plate 3, and the transmission cable is fixed to the spring 2 along the spiral axis of the spring 2. Through the spring 2, the transmission cable and the spring 2 can be fixed in a spiral structure in a ratio of approximately one to one, which is convenient for fixing and connecting the transmission cable. At the same time, the spring 2 also has a certain anti-roll performance, and the electric end and the power supply end are used to move relative to each other along the axial direction of the spring 2.

[0045] like Figures 1-2 As shown, based on the spring 2 as an elastic expansion member, in some embodiments, a connecting plate 4 is used to fix the spring 2 to the first connecting plate 1 or the second connecting plate 3; the connecting plate 4 is provided with a limiting channel 41 through which the arc wire at the end of the spring 2 passes, and the limiting channel 41 is an arc-shaped structure, which is consistent with the arc wire at the end of the spring 2, and is used to fix the end of the spring 2 to the first connecting plate 1 or the second connecting plate 3. In actual use, the connecting plate 4 can be used to fix the two ends of the spring 2 to the first connecting plate 1 and the second connecting plate 3 respectively.

[0046] In other embodiments, on the basis of fixing the spring 2 between the first connecting plate 1 and the second connecting plate 3 based on the connecting pressure plate 4, the connecting pressure plate 4 is bolted to the first connecting plate 1 and the second connecting plate 3 respectively. This connection method is simple, convenient for disassembly and assembly, and also convenient for later maintenance and replacement of the spring 2.

[0047] Based on the bolted connection between the connecting plate 4 and the first connecting plate 1 or the second connecting plate 3, other embodiments, such as Figure 2 As shown, the connecting plate 4 is provided with mounting holes on both sides of the limiting channel 41; the first connecting plate 1 is provided with a first threaded hole corresponding to the mounting hole, and the first threaded hole is threadedly connected with a first bolt 7 passing through the corresponding mounting hole.

[0048] On the basis of fixing the spring 2 to the first connecting plate 1 or the second connecting plate 3 based on the connecting pressure plate 4, in some embodiments, the connecting pressure plate 4 is evenly spaced at the end of the spring 2 with the axis of the spring 2 as the center, that is, the connecting pressure plate 4 is evenly spaced at the end of the spring 2 in the circumferential direction, and the circumferential ring formed by multiple connecting pressure plates 4 is coaxial with the spring 2. The connecting pressure plate 4 is evenly spaced at the circumferential direction to form multiple fixing points, which can fix the ring at the end of the spring 2 to the first connecting plate 1 or the second connecting plate 3 more stably and evenly. The multi-point fixing can enhance the connection strength and prevent the spring 2 from tilting and separating from the first connecting plate 1 or the second connecting plate 3 during the expansion and contraction process.

The guide ring 5 and the second connecting plate 3 are fixedly connected to form a barrel-shaped structure; preferably, the guide ring 5 is an open structure, and the guide ring 5 can further prevent the spring 2 from tilting. During the expansion and contraction process of the spring 2, if the transmission cable slips off the spring 2, the transmission cable can be supported to prevent the transmission cable from slipping and moving to other places to cause safety hazards.

[0050] like Figure 4As shown, based on the spring 2 as an elastic expansion member, in some embodiments, a guide angle frame 6 is fixedly provided on the second connecting plate 3 and is located in the annular space formed by the spring 2. The height of the guide angle frame 6 does not exceed the minimum distance threshold between the power consumption end and the power supply end, and the guide angle frame 6 may be a conical structure. In actual use, a triangular conical frame may be selected as the guide angle frame 6 fixedly connected to the second connecting plate 3, which can limit the roll of the spring 2 to a certain extent.

[0051] Based on the spring 2 being an elastic telescopic member, in some embodiments, the power transmission cable is fixed to the spiral structure of the spring 2 by means of buckles or cable ties in a multi-point fixed form, so that the power transmission cable and the spiral structure of the spring 2 can be almost identical, and can be synchronously expanded and contracted in the axial direction of the spring 2, which is easy to install.

[0052] In a certain embodiment, the first connection plate 1 is provided with a first wire hole, and one end of the transmission line passes through the first wire hole to connect to the power end or the power supply end; similarly, the second connection plate 3 is provided with a second wire hole, and the other end of the transmission line passes through the second wire hole to connect to the corresponding power supply end or the power end (corresponding to the power supply end or the power end connected to the second connection plate 3). The transmission cable can pass through the first wire hole and bypass the first connection plate 1 in a disorderly manner, so as to facilitate the connection to the power end or the power supply end.

[0053] In actual use, the arc wire at the end of the spring 2 is passed through the limiting channel 41 of the connecting pressure plate 4, and the multiple mounting holes of the connecting pressure plate 4 are aligned with the first threaded hole on the first connecting plate 1, and the mounting plate is fixed to the first connecting plate 1 using the first bolt 7; multiple connecting pressure plates 4 are fixed to the first connecting plate 1 at uniform intervals in the circumferential direction according to the above method; similarly, the other end of the spring 2 can be fixed to the second connecting plate 3 according to the above method; one end of the transmission cable is passed through the second wire hole of the second connecting plate 3, and the transmission cable is fixed to the spring 2 at multiple points along the spiral direction of the spring 2 using multiple cable ties; the other end of the transmission cable is passed through the first wire hole of the first connecting plate 1 to complete the assembly of the device; the first connecting plate 1 can be fixed to the power supply end device by U-bolts so that the transmission cable passing through the first wire hole is connected to the power supply end; the second connecting plate 3 is fixed to the power consumption end device by U-bolts so that the transmission cable passing through the second wire hole is connected to the power consumption end, and the circuit connection is completed when the power consumption end and the power supply end move relative to each other, so as to supply power to the power consumption end.
