Technical Field

[0001] This utility model relates to the technical field of special auxiliary equipment for cable reels, and in particular to a cable reel. Background Technology

[0002] In the specific implementation of the conversion of engineering machinery from oil to electricity via cable, there are two aspects: the arrangement of the motor controller and the method of cable routing.

[0003] I. Motor controller layout;

[0004] Vehicle-mounted: The motor controller (soft starter or frequency converter) is placed on the equipment. Although this structure is simple, it has been found in practice that the motor driver cannot withstand the long-term vibration of the equipment. After a period of use, it frequently fails or even breaks down, which seriously affects electrical safety and efficiency.

[0005] Remote type: The motor controller (soft starter or frequency converter) is placed outside the equipment, and the motor is started, stopped and monitored remotely. This structure is slightly more complex, but electrical safety and electrical control system safety are greatly improved.

[0006] II. Cable winding and unwinding methods;

[0007] Cable winding and unwinding are generally achieved using spring reels. Here, we take spring reels as an example. The installation locations of reels are divided into remote and vehicle-mounted types.

[0008] Whether it's vehicle-mounted or remote-controlled motor control, or vehicle-mounted or remote-controlled cable winding and unwinding, the motor must be controlled and monitored to effectively start and stop the motor, monitor and alarm parameters such as current and temperature, and the cable length must be monitored in real time to prevent it from exceeding the operating range and causing electrical safety accidents.

[0009] Currently, Chinese invention application number 201810963374.1 discloses an automatic matching system for cable winding and unwinding speed. Although when a mobile device equipped with a cable reel moves, the power mechanism automatically adjusts the speed of the reel winding and unwinding of the cable according to the vehicle speed to prevent the cable from piling up or being run over by the wheels, there are still problems. The cable does not have a temporary fixing device, the vehicle's start and stop have inertia, it is impossible to stably fix the cable and monitor the actual winding and unwinding length of the cable, and the cable will break if it is pulled out of the limit. Utility Model Content

[0010] The technical problem to be solved by this utility model is that the length of the cable cannot be accurately monitored and temporarily fixed, exceeding the working range can easily cause electrical safety accidents, the cable retracts too quickly, which can easily damage the cable, and the cable cannot be wound evenly, which will increase the risk of cable jamming.

[0011] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a winding device, which includes a motor, a winding shaft, a first rotating shaft, a reciprocating lead screw, a slider, a displacement sensor, a fixing plate, a fixing component, a reduction component, and a worktable.

One end of the spring is fixedly connected to the deceleration block, and the other end of the spring is fixedly connected to the rotating wheel. The rotating wheel is fixedly connected to a first rotating shaft, and the deceleration block abuts against the rotating wheel.

The first rotating shaft is rotatably connected to the first pulley, the first pulley is slidably connected to the belt, the belt is slidably connected to the second pulley, and the second pulley is fixedly connected to the reciprocating lead screw.

[0015] In a preferred embodiment of the cable reel described in this utility model, the rotating wheel is provided with a groove.

[0016] In a preferred embodiment of the winding device described in this utility model, the reciprocating screw has two threaded grooves with opposite directions of rotation.

[0022] In a preferred embodiment of the cable reel described in this utility model, an alarm is further included, wherein the alarm signal is connected to a displacement sensor.

[0023] The beneficial effects of this utility model are as follows: By monitoring the sliding displacement of the slider through a displacement sensor, the cable length can be monitored to prevent it from exceeding the working range. The first rotating shaft simultaneously drives the reciprocating screw to rotate, so that the cable can be wound evenly and prevent the cable from getting stuck.

Detailed Implementation

[0030] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0031] Example, refer to Figure 1-5This embodiment provides a cable reel, including a motor 1, a take-up shaft 2, a first rotating shaft 24, a reciprocating lead screw 4, a slider 41, a displacement sensor 5, a fixing plate 51, a fixing component 6, a reduction component 7, and a worktable 9. The output shaft of the motor 1 is rotatably connected to the first rotating shaft 24, the first rotating shaft 24 is rotatably connected to the take-up shaft 2, the reciprocating lead screw 4 is slidably connected to the slider 41, and the displacement sensor 5 is fixedly connected to the fixing plate 51.

[0032] The fixing component 6 includes a slot 61 and a block 62. The slot 61 is fixedly connected to the worktable 9, the block 62 engages with the slot 61, and the slot 61 is fixedly connected to the slider 41.

[0033] The deceleration component 7 includes a deceleration block 71, a spring 72, and a rotating wheel 73. One end of the spring 72 is fixedly connected to the deceleration block 71, and the other end of the spring 72 is fixedly connected to the rotating wheel 73. The rotating wheel 73 is fixedly connected to the first rotating shaft 24, and the deceleration block 71 abuts against the rotating wheel 73.

[0034] In this preferred embodiment, the motor controller is located outside the equipment, and remote control is used to start, stop, and monitor the construction machinery. The cable reel is remotely installed, and the displacement sensor 5 monitors the displacement of the slider 41, thereby monitoring the cable unwinding length to prevent exceeding the working range and causing electrical safety accidents. When operation is required, the motor 1 is started to drive the winding shaft 2 to unwind the cable. The first rotating shaft 24 simultaneously drives the reciprocating screw 4 to rotate, so that the cable can be wound evenly and prevent the cable from jamming. The reciprocating screw 4 enables the cable to be wound and unwound sequentially. When the cable is unwound to a suitable length... When the length is turned off, the motor 1 is turned on and the fixing component 6 is started. The locking block 62 rotates to tightly clamp the cable in the locking groove 61, thereby achieving temporary fixation of the cable and preventing the winding shaft 2 from becoming unstable due to inertial winding and breaking the cable. The deceleration component 7 decelerates both the winding and unwinding of the cable. When the first rotating shaft 24 rotates too fast, the deceleration block 71 slides relative to the rotating wheel 73, thereby increasing the damping of the rotating wheel 73. After the rotating wheel 73 decelerates, the spring 72 drives the deceleration block 71 to return to its original state, thereby reducing mechanical wear and preventing the engineering machinery from being pulled relative to the cable for a short time during mobile operation, which could lead to breakage.

[0035] Reference Figure 1 It also includes a first pulley 21, a second pulley 22 and a belt 23. A first rotating shaft 24 is rotatably connected to the first pulley 21. The first pulley 21 is slidably connected to the belt 23. The belt 23 is slidably connected to the second pulley 22. The second pulley 22 is fixedly connected to the reciprocating screw 4.

[0036] In this preferred embodiment, the first rotating shaft 24 drives the first pulley 21 to rotate, the first pulley 21 drives the second pulley 22 to rotate via the belt 23, and the second pulley 22 drives the reciprocating screw 4 to rotate. During the winding and unwinding process, the winding shaft 2 can drive the reciprocating screw 4 to slide, straighten the cable, and prevent the cable from getting stuck.

[0037] Reference Figure 2 The rotating wheel 73 has a sliding groove 731.

[0038] In this preferred embodiment, the deceleration block 71 can slide within the slide groove 731.

[0039] Reference Figure 1 The reciprocating lead screw 4 has two threaded grooves 401 with opposite directions of rotation.

[0040] In this preferred embodiment, the slider 41 can reciprocate on the threaded groove 401, which can not only rewind but also unwind.

[0041] Reference Figure 5 The slot 61 is provided with an arc-shaped groove 621, and the block 62 is provided with an arc-shaped protrusion that matches the arc-shaped groove 621.

[0042] In this preferred embodiment, the arc-shaped groove 621 facilitates the clamping of the cable and allows the clamping block 62 to exert more clamping force on the cable.

[0043] Reference Figure 5 The fixing component 6 also includes a connecting rod 63, a cylinder 64 and a limiting post 65. One end of the connecting rod 63 is rotatably connected to the locking block 62, and the other end of the connecting rod 63 is rotatably connected to the cylinder 64. The locking block 62 is rotatably connected to the locking groove 61 through the limiting post 65, and the cylinder 64 is fixedly connected to the locking groove 61.

[0044] In this preferred embodiment, when the cable is unwound to a certain length, allowing for free movement of the machinery within a certain range, the cylinder 64 is activated. The cylinder 64 retracts, causing the connecting rod 63 to move downwards. The connecting rod 63 then causes the locking block 62 to rotate, thereby locking the cable in the locking groove 61, which is beneficial for the stable operation of the cable.

[0045] Reference Figure 1 , 2 The worktable 9 is provided with a first slide rail 91, and the lower end of the slider 41 is provided with a pulley 411, which is slidably connected to the first slide rail 91.

[0046] In this preferred embodiment, the pulley 411 moves on the first slide rail 91 to facilitate the stable movement of the slider 41.

[0047] Reference Figure 3 The card slot 61 is equipped with a guide slider 611.

[0048] In this preferred embodiment, the slot 61 can slide on the worktable 9.

[0049] Reference Figure 1 , 2 The workbench 9 is equipped with a second slide rail 92, and the pulley 411 is slidably connected to the second slide rail 92.

[0050] In this preferred embodiment, pulley 411 is movable on the second slide rail 92.

[0051] Reference Figure 1 It also includes an alarm 8, whose signal is connected to a displacement sensor 5.

[0052] In this preferred embodiment, the alarm 8 is installed on the construction machinery. When the displacement sensor 5 measures that the unwinding length of the cable exceeds the control range, it transmits the information to the alarm 8, which then sounds an alarm, thereby reducing the operating distance of the construction machinery.

[0053] Working Principle: When the motor controller is located outside the equipment, remote control is used to start, stop, and monitor the construction machinery. The cable reel is remotely installed. The displacement sensor 5 monitors the displacement through the sliding displacement of the slider 41. The alarm 8 is installed on the construction machinery. When the displacement sensor 5 measures that the unwinding length of the cable exceeds the control range, it transmits the information to the alarm 8, which sounds an alarm, thereby reducing the working distance of the construction machinery. This allows for monitoring of the unwinding length of the cable, preventing it from exceeding the working range and causing electrical safety accidents. When operation is required, the motor 1 is started to drive the winding shaft 2 to unwind the cable. The first rotating shaft 24 drives the first pulley 21 to rotate, and the first pulley 21 drives the second pulley 22 to rotate via the belt 23. The second pulley 22 drives the reciprocating screw 4 to rotate. During the winding and unwinding process, the take-up shaft 2 can drive the reciprocating screw 4 to slide, straighten the cable, and ensure that the cable is wound evenly to prevent cable jamming. The reciprocating screw 4 can make the cable wind and unwind sequentially. When the cable is unwound to a suitable length, the motor 1 is turned off. When the cable is unwound to a certain length, it can meet the free movement of the machine within a certain range. The cylinder 64 is activated, and the cylinder 64 retracts, driving the connecting rod 63 to move downward. The connecting rod 63 drives the locking block 62 to rotate, thereby locking the cable in the locking groove 61. The rotation of the locking block 62 tightly clamps the cable in the locking groove 61, thereby achieving temporary fixation of the cable and preventing the take-up shaft 2 from becoming unstable due to inertial winding, which could break the cable and is conducive to the stable operation of the cable.

[0054] The deceleration component 7 decelerates the cable during winding and unwinding. When the first rotating shaft 24 rotates too fast, the deceleration block 71 slides relative to the rotating wheel 73, thereby increasing the damping of the rotating wheel 73. After the rotating wheel 73 decelerates, the spring 72 drives the deceleration block 71 to return to its original state, thereby reducing mechanical wear and preventing the engineering machinery from being pulled relative to the cable for a short time during mobile operation, which could lead to breakage.

[0055] This device can evenly wind cables to prevent them from jamming, monitor the cable length to prevent it from exceeding the operating range, and slow down the cable during winding and unwinding to prevent cable breakage, thus contributing to the stable operation of construction machinery.
