Description

Technical Field

[0001] This invention belongs to the field of cable placement technology, and particularly relates to a device and method for placing cables in a generator vehicle. Background Technology

[0002] When using a mobile generator for emergency power generation, the onboard cable needs to be released and connected to the user. However, if... Figure 4 As shown, the cables in existing generator cars are quite long and are usually placed in a loop. To avoid the generation of eddy currents, they are usually wrapped in multiple loops on the ground, which is messy and inconvenient to store and organize.

[0003] The inventors discovered that most cable winding devices are suitable for scenarios where one end of the cable is fixed before winding. However, in emergency power generation scenarios using generator trucks, winding needs to begin in the middle of the cable, rendering most current cable winding devices unsuitable. Furthermore, the cable winding devices currently used in emergency generator truck scenarios are not only complex in structure, but also require cable clamps or winding hooks to secure the cable before winding. Using cable clamps requires cumbersome operation by workers, affecting efficiency, while using winding hooks cannot secure the cable well, often resulting in unstable cable fixation and affecting the winding effect. Summary of the Invention

[0004] To address the aforementioned problems, this invention proposes a device and method for placing cables in a generator vehicle. The middle position of the winding roller is configured as an embedded tube, and a long groove is formed on the elastic embedded tube. A first opening and a second opening are respectively formed at both ends of the long groove. Before the cable is wound up, the middle position of the cable segment to be wound up is inserted into the long groove. The two ends of the middle position of the cable extend out of the long groove through the first opening and the second opening, respectively. The cable is fixed before winding up through a simple mechanism, which is simple to operate and has good fixation stability.

[0005] To achieve the above objectives, in a first aspect, the present invention provides a power generation vehicle cable placement device, which adopts the following technical solution:

[0006] A generator cable placement device includes a drive mechanism and a take-up roller connected to the drive mechanism;

[0007] The take-up roller includes a tube, and a first wire-blocking disc and a second wire-blocking disc disposed at both ends of the tube; the tube is made of an elastic material, and a long groove is formed on the tube, with a first opening and a second opening respectively at both ends of the long groove;

[0008] Before the cable is wound up, the middle position of the cable segment to be wound up is inserted into the long groove; the two ends of the middle position of the cable segment to be wound up extend out of the long groove through the first opening and the second opening, respectively.

[0009] Furthermore, the first opening is oriented in the opposite direction to the second opening.

[0010] Furthermore, the axes of the first opening and the second opening are both perpendicular to the plane of symmetry of the long groove in the length direction.

[0011] Furthermore, the drive mechanism is disposed inside the housing; a rotating shaft is rotatably disposed on one side wall of the housing, the end of the rotating shaft located outside the housing is connected to the take-up roller, and the end of the rotating shaft located inside the housing is connected to the drive mechanism.

[0012] Furthermore, a power supply is provided on the housing; the power supply is connected to the drive mechanism through a control mechanism.

[0013] Furthermore, the drive mechanism includes a first drive source, a worm connected to the first drive source, a worm wheel meshing with the worm, a first gear disposed at one end of the worm wheel, an internal gear ring meshing with the first gear, and a second gear meshing with the internal gear ring; the second gear is connected to the take-up roller via a rotating shaft.

[0014] Furthermore, an unlocking mechanism is provided on the internal gear ring.

[0015] Furthermore, the unlocking mechanism includes a second drive source and a sliding ring connected to the second drive source; the sliding ring is connected to the internal toothed ring.

[0016] Furthermore, the two sides of the long groove are configured with arc-shaped structures.

[0017] To achieve the above objectives, in a second aspect, the present invention also provides a method for placing the power generation vehicle cable, employing the following technical solution:

[0018] A method for placing power generation vehicle cables, employing the power generation vehicle cable placement device as described in the first aspect, includes:

[0019] Before the cable is wound up, the middle position of the cable segment to be wound up is inserted into the long groove; the two ends of the middle position of the cable segment to be wound up extend out of the long groove through the first opening and the second opening, respectively.

[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0030] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0031] Example 1:

[0032] like Figure 4As shown, when using a mobile generator for emergency power generation, the cables on the vehicle need to be released and connected to the user. The cables in existing mobile generators are quite long and are generally laid in loops. To avoid eddy currents, they are usually wound multiple times on the ground, resulting in a messy and difficult-to-manage arrangement. Furthermore, when using a mobile generator for emergency power generation, the vehicle is typically parked by the roadside, and the cables are laid along the roadside, which can cause inconvenience to normal road use.

[0033] To address the problem of tangled cables, cable winding devices are needed for cable placement, reeling in cables to solve the issue of haphazard cable placement on the ground. However, emergency power generation using mobile generators is often characterized by time constraints and limited operating areas. This necessitates cable winding devices with simple structures and easy operation. However, current cable winding devices are mostly complex in structure and cumbersome in operation, severely impacting emergency power generation. For example, current cable winding devices used in mobile generator emergency scenarios are not only complex in structure, but also require cable clamps or winding hooks to secure the cable before winding. Using cable clamps requires cumbersome operation by workers, affecting efficiency, while using winding hooks often results in unstable cable fixation, affecting the winding effect.

[0034] In response to the above problems, such as Figure 1 As shown, this embodiment provides a generator cable placement device, including a drive mechanism 3 and a take-up roller 2 connected to the drive mechanism 3;

[0035] The take-up roller 2 includes a tube 23, and a first wire-blocking disc 21 and a second wire-blocking disc 22 disposed at both ends of the tube 23; the tube 23 is made of elastic material, and a long groove 2302 is provided on the tube 23, and a first opening 2301 and a second opening 2302 are respectively provided at both ends of the long groove 2302.

[0036] Before the cable is wound up, the middle position of the cable segment to be wound up is inserted into the long groove 2302; the two ends of the middle position of the cable segment to be wound up extend out of the long groove 2302 through the first opening 2301 and the second opening 2302 respectively.

[0037] Specifically, in this embodiment, the winding roller 2 includes an insert tube 23 and a first wire guide plate 21 and a second wire guide plate 22 disposed at both ends of the insert tube 23, thereby limiting the cable position. The insert tube 23 is made of elastic material and has a long groove 2302. The long groove 2302 has a first opening 2301 and a second opening 2302 at both ends. Before winding the cable, the middle position of the cable segment to be wound is inserted into the long groove 2302, thereby fixing the cable segment to be wound in a simple mechanism and operation. The long groove 2302 extends from both ends of the middle position of the cable segment to be wound through the first opening 2301 and the second opening 2302, respectively, so that the two ends of the cable segment to be wound are distributed at both ends of the insert tube 23, avoiding the problem of cable tangling at both ends, and meeting the requirements for segmented winding of cables in the emergency power generation scenario of the generator vehicle.

[0038] Optionally, both the first wire guide plate 21 and the second wire guide plate 22 are circular structures, such as a circular structure connected by multiple horizontal bars and an outer ring; the first wire guide plate 21 and the second wire guide plate 22 can be connected to the embedded tube 23 by bolts, interference fit with shaft holes, or other means.

[0039] The insert 23 can be made of elastic materials such as plastic. In other embodiments, in order to ensure the stability of the insert 23, the main body of the insert 23 can be made of rigid plastic or metal, and the two ends of the long groove 2302 can be made of plastic with a certain degree of flexibility. When the cable enters or exits the insert 23, the opening of the long groove 2302 can be increased by elasticity, so that the cable can smoothly enter or exit the insert 23 under the action of external force from the operator.

[0040] like Figure 2 As shown, in order to allow the cable to smoothly enter and exit the tube 23, the two sides of the long groove 2302 are set as arc-shaped structures; this reduces the contact area friction between the cable and the inner walls of the two sides of the long groove 2302 when the cable enters and exits the long groove 2302, which not only allows the cable to smoothly enter and exit the tube 23, but also avoids damage to the cable sheath when the two sides of the long groove 2302 have direct or similar structures.

[0041] In this embodiment, the first opening 2301 and the second opening 2302 are oriented in opposite directions, avoiding the problem of the cable being pulled out of the long groove 2302 during the initial winding stage. If the first opening 2301 and the second opening 2302 are oriented in the same direction, the cable at both ends of the long groove 2302 will experience the same force direction during the initial winding stage, making it easy to pull the cable out of the long groove 2302. However, by setting the first opening 2301 and the second opening 2302 in opposite directions, the cable at both ends of the long groove 2302 will also experience opposite force directions during the initial winding stage, preventing the cable from being pulled out of the long groove 2302 and improving stability.

[0042] In this embodiment, the axes of the first opening 2301 and the second opening 2302 are both perpendicular to the plane of symmetry of the long groove 2301 along its length. It can be understood that the directions of the first opening 230 and the second opening 2302 are perpendicular to the opening direction of the long groove 2301, further preventing the cable from being pulled out of the long groove 2302 during the initial winding stage. If the directions of the first opening 230 and the second opening 2302 are consistent with the opening direction of the long groove 2301, then during the initial winding stage, the cable can easily be pulled out of the long groove 2301 after being subjected to force.

[0043] like Figure 1 and Figure 3 As shown, the drive mechanism 3 is disposed inside the housing 1; a rotating shaft is rotatably disposed on one side wall of the housing 1, the end of the rotating shaft located outside the housing 1 is connected to the take-up roller 2, and the end of the rotating shaft located inside the housing 1 is connected to the drive mechanism 2.

[0044] Optionally, the housing 1 can be a metal or wooden housing. An insulating layer is provided on the bottom or the entire exterior of the housing 1 to prevent the cable from leaking and affecting the external environment. In use, the housing 1 can be placed on the ground, with the winding roller 2 positioned above it, forming a vertical cable winding device. This design saves operating space and is suitable for situations where the area of ​​a generator truck emergency power generation site is small.

[0045] In some embodiments, a weight block may be provided at the bottom of the housing 1, where the bottom refers to the end that contacts the ground during operation. The weight block improves the stability of the entire device and prevents it from tipping over during cable winding. Multiple fixing holes can also be provided on the outside of the housing 1. The housing 1 and the entire device can be secured by passing ropes through these holes and connecting them to external objects, further improving the device's stability and preventing tipping over during cable winding.

[0046] The rotating shaft can be a metal shaft, with a hole opened on one outer wall of the housing 1. A bearing is installed in the hole through a bearing seat, and by means of bolt connection or welding. The rotating shaft is connected to the inner ring of the bearing by means of interference fit or key connection. With the above configuration, the rotating shaft can be rotatably mounted on the housing 1.

[0047] The rotating shaft is located at one end outside the housing 1 and can be fixedly connected to the middle position of the second cable guide 22 by means of bolt connection, shaft hole interference connection or welding; when the driving mechanism 3 drives the rotating shaft to rotate, it drives the winding roller 2 to rotate, thereby realizing the winding of the cable.

[0048] Optionally, the drive mechanism 3 includes a first drive source 31, a worm gear 32 connected to the first drive source 31, a worm wheel 33 meshing with the worm gear 32, a first gear 34 disposed at one end of the worm wheel 33, an internal gear ring 35 meshing with the first gear 34, and a second gear 36 meshing with the internal gear ring 35; the second gear 36 is connected to the take-up roller 2 via a rotating shaft. This drive mechanism 3 is not only simple in structure, but also allows the first drive source 31 to be disposed on the side wall of the housing 1 through the worm gear transmission method, reducing the volume of the housing 1 and further meeting the requirement of a small working area.

[0049] The first driving source 31 can be a drive motor. The meshing of the worm 32 and the worm wheel 33 can change the horizontal rotation of the worm 32 to the vertical rotation of the worm wheel 33; here, horizontal and vertical refer to... Figure 1 In this context, it only indicates a change in the direction of force, not the actual direction.

[0050] Specifically, the first drive source 31 can be mounted on the housing 1 by bolts or welding; the output shaft of the first drive source 31 is fixedly connected to the worm gear 32 by welding or bolts, and the worm gear 32 rotates when the output shaft of the first drive source 31 rotates; the worm gear 32 can be rotatably mounted inside the housing 1 by a connecting shaft, one end of which is fixed to the bottom of the housing 1 by welding or bolts; the worm gear 32 is rotatably mounted on the connecting shaft by a bearing, for example, the inner ring of the bearing is fixed to the connecting shaft by interference fit or welding, and the outer ring is fixed to the worm gear 32 by welding or interference fit; the worm gear 32 and the first gear 34 are fixedly connected to the connecting shaft and other components by welding or bolts; the second gear 36 is not connected to the first gear 34, and the first gear 34 and the second gear 36 respectively mesh with the internal teeth of the internal gear ring 35; the second gear 36 is connected to the end of the rotating shaft away from the second guide plate 22 by bolts or keys.

[0051] During operation, the first drive source 31 operates, and the output shaft of the first drive source 31 drives the worm gear 32 to rotate. The rotation of the worm gear 32 drives the worm wheel 33 to rotate, the rotation of the worm wheel 33 drives the first gear 34 to rotate, the rotation of the first gear 34 drives the internal gear ring 35 to rotate, the rotation of the internal gear ring 35 drives the second gear 36 to rotate, and the rotation of the second gear 36 drives the rotating shaft and the second wire guide disc 22 to rotate, thereby causing the entire winding roller 2 to rotate and wind up the cable.

[0052] The internal gear ring 35 is provided with an unlocking mechanism 4, which can separate the internal gear ring 35 from the first gear 34. At this time, the first drive source 31 cannot drive the first gear 34 to rotate. This not only realizes the quick pause of cable winding, but also allows the worker to easily remove the cable wound on the winding roller 2 when the cable needs to be disassembled.

[0053] Optionally, the unlocking mechanism 4 includes a second drive source 41 and a sliding ring 42 connected to the second drive source 41; the sliding ring 42 is connected to the internal gear ring 35. The second drive source 41 can be configured as a telescopic mechanism such as an electrically controlled telescopic cylinder; the sliding ring 42 is fixed to the internal gear ring 35, and the sliding ring 42 and the internal gear ring 35 are fixed to the second drive source 41. Under the drive of the second drive source 41, the sliding ring 42 and the internal gear ring 35 can move in the vertical direction.

[0054] Specifically, when it is necessary to disassemble the cable, the electric telescopic cylinder moves the sliding ring 42 downward. The downward movement of the sliding ring 42 causes the internal gear ring 35 to move downward. The downward movement of the internal gear ring 35 separates the internal gear ring 35 from the second gear 36. The second gear 36 and the first gear 34 are no longer engaged by the internal gear ring 35, so the operator can easily stretch the cable and remove it.

[0055] A power supply 5 is provided on the housing 1; the power supply 5 is electrically connected to the drive mechanism 3 and the unlocking mechanism 4 through a control mechanism 6. It can be understood that the control mechanism 6 is a button or switch, etc., which can be used to control the power supply 5 and the energization and de-energization of the drive mechanism 3 and the unlocking mechanism 4, thereby controlling the operation and shutdown of the drive mechanism 3 and the unlocking mechanism 4.

[0056] Example 2:

[0057] This embodiment provides a method for placing power generation vehicle cables, employing the power generation vehicle cable placement device as described in Embodiment 1, including:

[0058] Before the cable is wound up, the middle position of the cable segment to be wound up is inserted into the long groove 2302; the two ends of the middle position of the cable segment to be wound up extend out of the long groove 2302 through the first opening 2301 and the second opening 2302 respectively.

[0059] The drive mechanism 3 drives the winding roller 2 to rotate, thereby winding up the cable.

Various modifications and variations can be made to this practice by those skilled in the art.
