Description

Technical Field

[0001] This disclosure relates to the technical field of lifting lights, and in particular to an electric rope winding device and an electric lifting light. Background Technology

[0002] Electric lifting lights are widely used in various venues requiring flexible lighting height adjustment, such as large exhibition halls, stadiums, and industrial plants, due to their convenient lifting operation and precise lighting positioning. The rope winding device, as the core component of the electric lifting light, plays a crucial role in winding and unwinding the rope to achieve the lifting and lowering of the light fixture; its performance directly determines the stability and safety of the lifting operation.

[0003] However, in order to adapt to the overall layout of the lamp or simplify some parts of the structure, the gears in the commonly used electric lifting lamp rope winding devices on the market are located off-center from the rope winding shaft. Due to the off-center gear position, the force exerted by the rope on the winding shaft during the lamp's lifting process cannot be evenly distributed. When the lamp is at different heights or under different loads, uneven force is easily caused. Especially when the lamp is heavy, the off-center gear structure is difficult to effectively bear and distribute the tension from the rope. Utility Model Content

[0004] The purpose of this disclosure is to overcome the shortcomings of the prior art and to provide an electric rope winding device and an electric lifting light that improves the load-bearing capacity and structural stability of the rope winding device by centrally placing the gear in the rope winding device.

[0005] The purpose of this disclosure is achieved through the following technical solution:

[0006] An electric rope winding device includes a housing structure, a turntable structure, and a drive structure. The housing structure includes an upper cover plate and a lower housing. The upper cover plate covers the lower housing. The lower housing has a turntable receiving cavity. The turntable structure is disposed within the turntable receiving cavity. The turntable structure includes a driven gear and a winding housing. The winding housing has a device receiving cavity. The driven gear is disposed at the geometric center of the winding housing. Both the driven gear and the drive structure are disposed within the device receiving cavity.

[0007] The drive structure includes a motor assembly and a drive gear. The motor assembly is connected to the drive gear, and the drive gear meshes with the driven gear. The winding housing has multiple interconnected hanging wire storage slots, which are spaced apart on the outer side wall of the winding housing away from the driven gear. The lower housing has a hanging wire outlet slot, which is connected to the hanging wire storage slots.

[0008] Both the hanging wire outlet groove and the hanging wire storage groove are used to accommodate the hanging rope. One end of the hanging rope is connected to the winding housing, and the other end of the hanging rope is used to connect to the lifting lamp body.

[0009] In one embodiment, the turntable structure further includes a plurality of reinforcing members, one end of each reinforcing member being connected to the driven gear, and the other end of each reinforcing member being connected to the inner wall of the winding housing, with the plurality of reinforcing members spaced apart from each other in the winding housing.

[0010] In one embodiment, the winding housing has a power connection hole at its geometric center, and the electric winding device further includes a power connection structure that passes through the power connection hole.

[0011] In one embodiment, the number of teeth of the drive gear is less than the number of teeth of the driven gear.

[0012] In one embodiment, the motor assembly includes a drive motor, a support frame, and a rotating shaft. The support frame has a motor receiving slot and a rotating through hole. The motor receiving slot communicates with the rotating through hole. The drive motor is received in the motor receiving slot and fixed to the support frame. One end of the rotating shaft is rotatably connected to the power output end of the drive motor, and the other end of the rotating shaft passes through the rotating through hole. The drive gear has a rotating cavity, and the other end of the rotating shaft is also engaged in the rotating cavity.

[0013] In one embodiment, the drive motor has a first fixed through hole, the support frame has a second fixed through hole, the first fixed through hole is connected to the second fixed through hole, and the first fixed through hole and the second fixed through hole are used to pass through fasteners.

[0014] In one embodiment, the upper cover plate has a third fixing through hole, and the support frame has a fourth fixing through hole. The third fixing through hole and the fourth fixing through hole are arranged opposite to each other, and the third fixing through hole and the fourth fixing through hole are used to pass through fasteners.

[0015] In one embodiment, the upper cover plate is provided with a plurality of fixing bosses, each of the fixing bosses having a first connecting through hole, and the lower housing having a plurality of second connecting through holes, each of the first connecting through holes and a second connecting through hole being disposed opposite to each other, and the first connecting through holes and the second connecting through holes being used to pass through fasteners.

[0016] In one embodiment, a fixed through groove is provided at the geometric center of the lower housing, and the power connection structure is fixed in the fixed through groove.

[0017] This application also provides an electric lifting light, including the electric rope winding device described in any embodiment.

[0018] Compared with the prior art, this disclosure has at least the following advantages:

[0019] In the aforementioned electric rope winding device, the driven gear is positioned at the geometric center of the winding housing, ensuring uniform force distribution on the housing during rotation. When the suspension rope connects to the lamp body, the weight of the lamp body is transferred to the winding housing via the rope. Because the driven gear is located at the geometric center, the torque generated by the tension applied by the suspension rope on the winding housing is evenly distributed, avoiding localized stress concentration and reducing the risk of deformation or damage to the winding housing. This improves the structural stability of the electric rope winding device and helps maintain the balance of the turntable structure, increasing its load-bearing capacity and thus enhancing its applicability.

[0029] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0030] like Figures 1 to 5 As shown, an embodiment of the electric rope winding device 10 of this disclosure includes a housing structure 100, a turntable structure 200, and a drive structure 300. The housing structure 100 includes an upper cover plate 110 and a lower housing 120. The upper cover plate 110 covers the lower housing 120. The lower housing 120 is provided with a turntable receiving cavity 1201. The turntable structure 200 is disposed in the turntable receiving cavity 1201. The turntable structure 200 includes a driven gear 210 and a winding housing 220. The winding housing 220 is provided with a device receiving cavity 2201. The driven gear 210 is disposed at the geometric center of the winding housing 220. The driven gear 210 and the drive structure 300 are both disposed in the device receiving cavity 2201.

[0031] The drive structure 300 includes a motor assembly 310 and a drive gear 320. The motor assembly 310 is connected to the drive gear 320, and the drive gear 320 meshes with the driven gear 210. The winding housing 220 has multiple interconnected hanging wire storage slots 2202, which are spaced apart on the outer side wall of the winding housing 220 away from the driven gear 210. The lower housing 120 has a hanging wire outlet slot 1202, which is connected to the hanging wire storage slot 2202.

[0032] The cable outlet groove 1202 and the cable storage groove 2202 are both used to accommodate the cable 500. One end of the cable 500 is connected to the winding housing 220, and the other end of the cable 500 is used to connect to the lamp body of the lifting lamp.

[0033] In this embodiment, when the height of the lifting lamp body needs to be adjusted, the motor assembly 310 in the drive structure 300 is activated, and then the motor assembly 310 drives the drive gear 320 to rotate. Since the drive gear 320 meshes with the driven gear 210, according to the principle of gear transmission, the rotation of the drive gear 320 will drive the driven gear 210 to rotate synchronously. The driven gear 210 is located at the geometric center of the winding housing 220, so that when the driven gear 210 rotates, it can drive the winding housing 220 to rotate stably around the geometric center as an axis. During the rotation of the winding housing 220, the suspension rope 500, which is wound on the winding housing 220 and located in the suspension rope storage groove 2202, will gradually be released from the suspension rope storage groove 2202 as the winding housing 220 rotates. As the suspension rope 500 is continuously released, the lifting lamp body connected to the other end of the suspension rope 500 will slowly descend under the action of gravity until it reaches the height position required by the user. When the lamp body needs to be raised, the control motor assembly 310 reverses its rotation, and the drive gear 320 rotates in the opposite direction, which in turn drives the driven gear 210 and the winding housing 220 to rotate in the opposite direction. At this time, the suspension rope 500 will be rewound back into the suspension rope storage groove 2202 under the drive of the winding housing 220. The suspension rope 500 is gradually retracted through the suspension rope outlet groove 1202, and the lamp body rises slowly under the tension of the suspension rope 500 until it reaches the appropriate height.

[0034] Furthermore, the driven gear 210 is positioned at the geometric center of the winding housing 220, ensuring uniform force distribution on the winding housing 220 during rotation. When the suspension rope 500 connects to the lamp body, the weight of the lamp body is transferred to the winding housing 220 via the suspension rope 500. Because the driven gear 210 is located at the geometric center, the torque generated by the tension applied by the suspension rope 500 on the winding housing 220 can be evenly distributed, avoiding local stress concentration in the winding housing 220 due to uneven force distribution. This reduces the risk of damage to the winding housing 220 due to excessive local stress and improves the structural stability of the electric rope winding device 10.

[0035] In the aforementioned electric rope winding device 10, the driven gear 210 is located at the geometric center of the winding housing 220, ensuring uniform force distribution on the winding housing 220 during rotation. When the suspension rope 500 is connected to the lamp body, the weight of the lamp body is transmitted to the winding housing 220 via the suspension rope 500. Because the driven gear 210 is located at the geometric center, the torque generated by the tension applied by the suspension rope 500 on the winding housing 220 can be evenly distributed, avoiding local stress concentration and reducing the risk of deformation or damage to the winding housing 220. This improves the structural stability of the electric rope winding device 10 and helps maintain the balance of the turntable structure 200, increasing the load-bearing capacity of the turntable structure and thus enhancing the applicability of the electric rope winding device 10.

[0036] like Figure 4 As shown, in one embodiment, the turntable structure 200 further includes multiple reinforcing members 230. One end of each reinforcing member 230 is connected to the driven gear 210, and the other end of each reinforcing member 230 is connected to the inner wall of the winding housing 220. The multiple reinforcing members 230 are spaced apart in the winding housing 220. In this embodiment, when the winding housing 220 bears the weight of the lifting lamp body transmitted by the suspension rope 500 during rotation, the reinforcing members 230 can share part of the force, dispersing the force originally concentrated at the connection between the winding housing 220 and the driven gear 210 to the inner wall of the winding housing 220. This enhances the connection strength between the winding housing 220 and the driven gear 210, allowing the entire turntable structure 200 to maintain structural integrity even under heavy loads. This effectively prevents the connection from breaking due to excessive force, further improving the structural stability of the electric rope winding device 10.

[0037] like Figure 3 and Figure 4 As shown, in one embodiment, the winding housing 220 has a power connection hole 2203 at its geometric center, and the electric winding device 10 also includes a power connection structure 400, which passes through the power connection hole 2203. In this embodiment, since the power connection hole 2203 is located at the geometric center of the winding housing 220, when the winding housing 220 rotates under the drive of the motor assembly 310, the power connection structure 400 can always maintain a relatively stable position and will not undergo a large displacement due to the rotation of the winding housing 220. This makes the connection between the power connection structure 400 and the external power supply and other electrical components inside the device more reliable, avoiding electrical faults caused by loose connections or poor contact.

[0038] like Figure 3 and Figure 4 As shown, in one embodiment, the number of teeth on the drive gear 320 is less than the number of teeth on the driven gear 210. In this embodiment, according to the gear transmission principle, when the number of teeth on the drive gear 320 is less than the number of teeth on the driven gear 210, a reduction transmission ratio is formed. The high-speed rotational motion output by the motor assembly 310, after being meshed and transmitted between the drive gear 320 and the driven gear 210, will reduce the rotational speed of the driven gear 210 and the winding housing 220 connected to it, while the torque will increase accordingly. For the electric rope winding device 10, the larger torque can better cope with the resistance generated by the lifting lamp body during the lifting process, so that even when the lamp body is heavy or subjected to great resistance, the winding housing 220 can still rotate stably, ensuring that the suspension rope 500 can be released or retracted smoothly, thereby achieving precise adjustment of the height of the lifting lamp body.

[0039] like Figure 3 and Figure 5As shown, in one embodiment, the motor assembly 310 includes a drive motor 311, a support frame 312, and a rotating shaft 313. The support frame 312 has a motor receiving slot 3101 and a rotating through hole 3102. The motor receiving slot 3101 communicates with the rotating through hole 3102. The drive motor 311 is received in the motor receiving slot 3101 and fixed to the support frame 312. One end of the rotating shaft 313 is rotatably connected to the power output end of the drive motor 311, and the other end of the rotating shaft 313 passes through the rotating through hole 3102. Please refer to the attached document. Figure 2 The drive gear 320 has a rotating cavity 3201, and the other end of the rotating shaft 313 is also locked inside the rotating cavity 3201. In this embodiment, when the drive motor 311 starts, the power it generates can be transmitted to the drive gear 320 through the rotating shaft 313. The efficient transmission method ensures that the electric rope winding device 10 can quickly respond to operation commands and adjust the height of the lifting lamp body in a timely manner, thereby improving the working efficiency of the device. During the rotation process, the rotating shaft 313 can maintain a stable speed and torque output, so that the drive gear 320 can rotate smoothly, thereby driving the driven gear 210 and the winding housing 220 to operate stably, thus ensuring the smooth release and retraction of the suspension rope 500.

[0040] like Figure 5 As shown, in one embodiment, the drive motor 311 has a first fixing through hole 3103, and the support frame 312 has a second fixing through hole 3104. The first fixing through hole 3103 communicates with the second fixing through hole 3104, and both the first fixing through hole 3103 and the second fixing through hole 3104 are used to insert fasteners. In this embodiment, during actual assembly, the drive motor 311 can be firmly fixed to the support frame 312 by inserting fasteners through the first fixing through hole 3103 and the second fixing through hole 3104. This ensures a tight connection between the drive motor 311 and the support frame 312. Specifically, the communication design between the first fixing through hole 3103 and the second fixing through hole 3104, along with the use of fasteners for fixing, effectively prevents the drive motor 311 from shifting during operation, ensuring that the motor is always in a stable working state. This ensures that the entire electric rope winding device 10 can operate normally and achieve precise adjustment of the height of the lifting lamp body.

[0041] like Figure 3 and Figure 5As shown, in one embodiment, the upper cover plate 110 has a third fixing through hole 1101, and the support frame 312 has a fourth fixing through hole 3105. The third fixing through hole 1101 and the fourth fixing through hole 3105 are arranged opposite to each other, and the third fixing through hole 1101 and the fourth fixing through hole 3105 are used to pass through fasteners. In this embodiment, since the upper cover plate 110 and the support frame 312 are connected by fasteners, the drive motor 311 and the upper cover plate 110 form an organic whole. During the operation of the electric rope winding device 10, the drive motor 311 will generate a certain amount of vibration and impact force. By connecting the third fixed through hole 1101 and the fourth fixed through hole 3105, the upper cover plate 110 and the support frame 312 are tightly connected by fasteners. This effectively disperses the vibration and impact force generated by the drive motor 311 to the upper cover plate 110 and the entire housing structure 100, avoiding structural loosening caused by excessive local stress. This ensures the stability and reliability of the electric rope winding device 10 during long-term operation.

[0042] like Figure 2 As shown, in one embodiment, the upper cover plate 110 has a plurality of fixing bosses 111, each fixing boss 111 having a first connecting through hole 1102, and the lower housing 120 has a plurality of second connecting through holes 1203, each first connecting through hole 1102 and a second connecting through hole 1203 being arranged opposite to each other, and the first connecting through holes 1102 and the second connecting through holes 1203 being used to pass fasteners. In this embodiment, during the actual assembly process, the operator can easily align the fixing bosses 111 of the upper cover plate 110 with the corresponding positions of the lower housing 120, so that the first connecting through holes 1102 and the second connecting through holes 1203 are accurately corresponding. Subsequently, by passing in suitable fasteners, the upper cover plate 110 can be firmly fixed to the lower housing 120, avoiding structural loosening or misalignment caused by connection deviation, thereby enhancing the structural stability of the entire electric rope winding device 10.

[0043] like Figure 2 and Figure 3As shown, in one embodiment, a fixed through groove 1204 is provided at the geometric center of the lower housing 120, and the power connection structure 400 is fixed within the fixed through groove 1204. In this embodiment, since the fixed through groove 1204 is located at the geometric center of the lower housing 120, during the operation of the electric rope winding device 10, even if the winding housing 220 continues to rotate under the drive of the motor assembly 310, the power connection structure 400 can maintain a relatively stable position with the help of the stable support of the fixed through groove 1204. This effectively avoids the shaking or displacement caused by the rotation of the winding housing 220, ensuring that the connection between the power connection structure 400 and the external power supply and other electrical components inside the device remains reliable, reducing electrical faults caused by loose connections or poor contact, and thus ensuring the normal operation of the electric rope winding device 10.

[0044] This application also provides an electric lifting lamp, including an electric rope winding device according to any embodiment. In this embodiment, when it is necessary to adjust the height of the lifting lamp body, the motor assembly 310 in the drive structure 300 is activated, and then the motor assembly 310 drives the drive gear 320 to rotate. Since the drive gear 320 meshes with the driven gear 210, according to the principle of gear transmission, the rotation of the drive gear 320 will drive the driven gear 210 to rotate synchronously. The driven gear 210 is located at the geometric center of the winding housing 220, so that when the driven gear 210 rotates, it can drive the winding housing 220 to rotate stably about the geometric center as an axis. During the rotation of the winding housing 220, the suspension rope 500 wound on the winding housing 220 and located in the suspension rope storage groove 2202 will gradually be released from the suspension rope storage groove 2202 as the winding housing 220 rotates. As the suspension rope 500 is continuously released, the lifting lamp body connected to the other end of the suspension rope 500 will slowly descend under the action of gravity until it reaches the height position required by the user. When the lamp body needs to be raised, the control motor assembly 310 reverses its rotation, causing the drive gear 320 to rotate in the opposite direction, which in turn drives the driven gear 210 and the winding housing 220 to rotate in the opposite direction. At this time, the suspension rope 500 will be rewound back into the suspension rope storage groove 2202 under the drive of the winding housing 220, and the suspension rope 500 will be gradually retracted through the suspension rope outlet groove 1202. The lamp body will then slowly rise under the tension of the suspension rope 500 until it reaches the appropriate height. Furthermore, the driven gear 210 is located at the geometric center of the winding housing 220, so that the winding housing 220 is subjected to uniform force during rotation. When the suspension rope 500 is connected to the lamp body, the weight of the lamp body is transferred to the winding housing 220 through the suspension rope 500. Since the driven gear 210 is located at the geometric center, the torque generated by the tension applied by the suspension rope 500 on the winding housing 220 can be evenly distributed, avoiding local stress concentration in the winding housing 220 due to uneven force, thereby reducing the risk of damage to the winding housing 220 due to excessive local force and improving the structural stability of the electric rope winding device 10.

[0045] Compared with the prior art, this disclosure has at least the following advantages:

[0046] In the aforementioned electric rope winding device 10, the driven gear 210 is located at the geometric center of the winding housing 220, ensuring uniform force distribution on the winding housing 220 during rotation. When the suspension rope 500 is connected to the lamp body, the weight of the lamp body is transmitted to the winding housing 220 via the suspension rope 500. Because the driven gear 210 is located at the geometric center, the torque generated by the tension applied by the suspension rope 500 on the winding housing 220 can be evenly distributed, avoiding local stress concentration and reducing the risk of deformation or damage to the winding housing 220. This improves the structural stability of the electric rope winding device 10 and helps maintain the balance of the turntable structure 200, increasing the load-bearing capacity of the turntable structure and thus enhancing the applicability of the electric rope winding device 10.

[0047] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
