Description

Cable drum pooling device

The present invention relates to a cable drum pulling device. More specifically, the present invention relates to a cable drum pulling device, and more specifically, a fixed plate that is seated on the ground, and a rotating plate that is rotatably installed on the upper side of the fixed plate with a cable drum seated thereon, are formed to have a thrust bearing structure, so that the structure is simple and robust. This relates to a cable drum pulling device that allows stable release of heavy cable drums.

In general, a cable drum that wraps a certain amount of cables is mainly used to handle, transport, and store various types of cables such as communication cables and transmission cables.

A cable drum is a cylindrical drum-shaped reel frame made of wood, metal, synthetic resin, etc., and the size of the cable drum varies depending on the type, standard, and amount of winding of the cable. It is a device on which a large amount of transmission cable is wound. In the case of cable drums, the maximum weight can reach 3 tons.

Meanwhile, when working with cables, such as unwinding or installing a cable wrapped around a cable drum, it is important for the speed and convenience of work that the cable drum rotates as much as the user unwinds the cable, allowing the cable to easily unwind. For this purpose, a cable drum pulling device is used to support the cable drum so that it can rotate so that the cable drum can rotate smoothly while the cable drum is loaded.

However, the conventional cable drum pulling device has the disadvantage that when the weight of the cable drum is heavy, the cable drum cannot rotate smoothly and the cable cannot be released.

In addition, when used on a tilted ground, there is a disadvantage that the cable drum pulling device is frequently damaged or broken as the load of the cable drum is shifted to one side.

In addition, in the conventional cable drum pulling device, the cable drum rotates and the cable is released due to the force with which the user pulls the cable. If the cable drum is light and the user suddenly pulls the cable with strong force, the cable is pulled out as intended by the user. As the cable drum rotates more excessively, the untangled cables become tangled with each other, which is a disadvantage in that the user often has to untangle the tangled cables one by one.

In addition, in the process of unwinding a cable from a cable drum on which a certain length of cable is wound, the length of the unraveled cable and the length of the remaining cable cannot be immediately determined, resulting in an unexpected shortage of cable during work, resulting in the use of cable. There are also frequent downsides to not being able to complete a task.

The fixing plate 10 includes a rotating shaft 103 and a first annular groove 101.

The rotation axis 103 is installed vertically at the center of the fixing plate 10.

The first annular groove 101 is formed on the upper surface of the rotating plate 20. At this time, the first annular groove 101 is preferably formed in an arc-shaped cross section with a predetermined curvature, and inside the first annular groove 101, a plurality of bearing balls 102 corresponding to the curvature of the first annular groove 101 are provided. It is filled to minimize the gap between balls so that they can rotate.

It should be noted in advance that the diameter of the first annular groove 101 is not limited.

The material of the bearing ball 102 is not limited, and the diameter is preferably 3 to 100 mm.

The rotating plate 20 includes a second annular groove 201 and a protruding rod 202.

The rotating plate 20 is coupled to a rotating shaft 103 installed vertically at the center of the fixed plate 10 to enable idling.

The rotating shaft 103 may be composed of a body and a head like a bolt, and the body may penetrate the rotating plate 20 vertically and be fastened with a nut.

At this time, a bearing 103a is interposed between the head of the rotating shaft 103 and the rotating plate 20, so that the body portion can be installed to penetrate the bearing 103a, and the bearing 103a is also installed between the fixed plate 10 and the rotating plate 20. With this intervention, the body portion can be installed to penetrate the bearing 103a.

The second annular groove 201 is formed on the bottom of the rotating plate 20 symmetrically with the first annular groove 101.

Therefore, the bearing ball 102 filled in the first annular groove 101 is inserted into the second annular groove 201 of the rotating plate 20 installed to enable idling on the rotating shaft 103, so that the rotating plate 20 has a bearing ball ( It is rotatably supported by 102).

The protruding rod 202 is installed at the center of the upper surface of the rotating plate 20.

It should be noted that the cross-sectional shape, height, and diameter of the protruding rod 202 are not limited.

A plurality of the support members 30 are installed on the bottom of the fixing plate 10 so that the fixing plate 10 maintains a constant distance from the ground.

The material of the support member 30 is not limited, and the height of the support member 30 is preferably 3 to 10 cm.

The cable drum pulling device of the present invention configured as described above seats the cable drum on the upper surface of the rotating plate 20 with the support member 30 placed in close contact with the ground, and then pulls the cable wound around the cable drum, thereby pulling the cable. As the rotating plate 20 rotates due to the pulling force, the cable drum mounted on the rotating plate 20 rotates together, making it possible to easily unwind the cable wound around the cable drum.

In particular, the rotating plate 20, which is rotatably supported by a plurality of bearing balls 102 installed in the first annular groove 101 of the fixed plate 10, has a thrust bearing structure together with the fixed plate 10, so that the structure is simple and Even if the weight of the cable drum seated on the upper surface of the rotating plate 20 increases as it becomes stronger, the weight of the cable drum is distributed by the plurality of bearing balls 102 installed in the first annular groove 101, thereby maintaining the rotating plate 20. Stable rotation is guaranteed, which has the effect of stably releasing even heavy cable drums.

Figure 6 is a perspective view according to a second embodiment of the cable drum pulling device of the present invention, and Figure 7 is a state diagram of the cable drum pulling device according to the second embodiment of the present invention.

The description will be made with reference to FIGS. 6 and 7, but detailed descriptions of components overlapping with the above-described embodiments and components having the same reference numerals will be omitted.

In one embodiment, the support member 30 of the present invention may be screwed to the bottom of the fixing plate 10 to enable height adjustment.

Additionally, at least one level 203 is installed on the upper surface of the rotating plate 20.

It is preferable that the levelers 203 are installed in a right angle direction.

Therefore, when the ground of the work site where cable work is required is inclined, the horizontality of the fixing plate 10 can be adjusted by adjusting the height of each support member 30 screwed to the bottom of the fixing plate 10.

In addition, in the process of adjusting the level of the fixing plate 10 using the support member 30, the level of the fixing plate 10 is adjusted while looking at the level 203 of the rotating plate 20, so that the level of the fixing plate 10 can be easily set. do.

Therefore, even on a sloping ground, the rotating plate 20 is leveled through the horizontal setting of the fixing plate 10, so that the cable drum that is seated on the upper surface of the rotating plate 20 is leveled, and the cable dream rotates in the process of unwinding the cable. The rotation of the cable drum becomes stable, which has the effect of stably maintaining the unwinding of the cable.

Figure 8 is an exemplary side view according to a third embodiment of the cable drum pulling device of the present invention.

Although the description will be made with reference to FIG. 8, detailed descriptions of components overlapping with the above-described embodiments and components having the same reference numerals will be omitted.

In one embodiment, one side of the fixing plate 10 of the present invention may be further provided with a pressure control means 40 that adjusts the rotation speed of the rotating plate 20 by applying frictional force to the outer surface of the rotating plate 20.

The pressure regulating means 40 includes a friction member 401 and a pressing member.

The friction member 401 is installed at the tip of the pressing member and generates frictional force by contacting the outer surface of the rotating plate 20.

It should be noted in advance that the outer surface of the rotating plate 20 that the friction member 401 contacts is preferably the outer peripheral surface of the rotating plate 20, but is not limited thereto.

The material of the friction member 401 is not limited, and the shape of the friction member 401 can be any shape as long as it is in close contact with the outer surface of the rotating plate 20.

As an example, when the friction member 401 is in contact with the outer peripheral surface of the rotating plate 20, the contact surface of the friction member 401 is preferably formed in a concave arc shape corresponding to the curvature of the outer peripheral surface of the rotating plate 20.

The pressing member is installed in the housing 104 formed on one side of the fixing plate 10, and not only applies pressure in the center direction of the fixing plate 10, but also makes it possible to control the applied pressure.

As an example, the pressing member may be an adjustment bolt 402a screwed to the housing 104.

Therefore, when the adjustment bolt 402a is tightened, the body of the adjustment bolt 402a approaches the outer surface of the rotating plate 20, and the friction force between the outer surface of the rotating plate 20 and the friction member 401 increases,

When the adjustment bolt 402a is loosened, the body portion of the adjustment bolt 402a moves away from the outer surface of the rotating plate 20, thereby reducing the friction between the outer surface of the rotating plate 20 and the friction member 401.

Meanwhile, an elastic member 403 may be further provided between the friction member 401 and the pressing member.

Therefore, the elastic member 403 absorbs and alleviates the vibration or shock that occurs when the rotating plate 20 rotates while the friction member 401 is in contact with the outer surface of the rotating plate 20, thereby suppressing transmission to the pressing member. can do.

As another example, the pressing member may be an actuator 402b, and is preferably an electric actuator 402b driven by a battery.

Therefore, the friction force between the outer surface of the rotating plate 20 and the friction member 401 is adjusted according to the stroke of the actuator 402b.

As described above, by controlling the strength of the pressure (friction force) acting on the outer surface of the rotating plate 20 using the pressure control means 40, it is possible to control the rotation speed when the rotating plate 20 rotates.

In other words, when the user pulls the cable to release the cable while the cable drum is seated on the upper surface of the rotating plate 20, the rotating plate 20 rotates due to the force. The rotational speed of the rotating plate 20 is determined by the pulling force of the cable. It is proportional to the size and speed of the force.

Therefore, if the size or speed of the force pulling the cable is excessive, the cable drum along with the rotating plate 20 rotates excessively, causing the unraveled cable to become entangled. The pressure control means 40 is used to adjust the excessive rotation of the rotating plate 20. Inhibiting rotation prevents cables from becoming tangled when the cable drum overrotates.

Figure 9 is an exemplary side view according to a fourth embodiment of the cable drum pulling device of the present invention.

The description will be made with reference to FIG. 9, but detailed descriptions of components overlapping with the above-described embodiments and components having the same reference numerals will be omitted.

In one embodiment, the cable drum pulling device of the present invention may further include a sensor means 50, a communication means 60, and a mobile device 70.

The sensor means 50 is installed on one side of the fixing plate 10 and detects rotation information of the rotating plate 20, that is, one or more of the rotation number, rotation direction, and rotation angle of the rotating plate 20.

The communication means 60 is installed on one side of the fixing plate 10 and transmits rotation information measured by the sensor means 50 to the mobile device 70.

The communication means 60 is equipped with a short-range wireless communication module such as Wi-Fi, Bluetooth, ZigBee, etc. to transmit data to a mobile device 70 located in a short distance, or is equipped with a dedicated communication module to transmit data. Data can be transmitted to a mobile device 70 located at a distance using a telecommunication company's Internet network capable of long-distance transmission, or a mobile communication network such as a WCDMA network, 3G LTE network, 4G network, or 5G network.

As another example, the sensor means 50 detects the posture information of the fixed plate 10, that is, the tilt information of the fixed plate 10, and transmits the posture information of the fixed plate 10 through the communication means 60 to the mobile device ( 70).

The mobile device 70 is a device capable of exchanging data through communication means, and is a comprehensive concept of portable devices. That is, PDA (Personal Digital Assistant), GSM (Global System for Mobile) phone, WCDMA (Wide band CDMA) phone, CDMA-2000 phone, MBS (Mobile Broad and System) phone, PMP (Portable Multimedia Player), handheld computer. It may include multimedia phones and multimedia players, such as (Handheld Computer).

The mobile device 70 is equipped with a dedicated application.

The dedicated application is a program installed on a mobile device for efficient use of the cable drum pulling device of the present invention. Using the dedicated application, work efficiency using cables can be improved.

As an example, if the specifications of the cable drum (type of drum, diameter of drum, type of cable, diameter of cable, length of cable, etc.) are pre-entered into the dedicated application, a communication means (60) is used when unwinding the cable from the cable drum. Using the rotation information of the rotary plate 20 transmitted from ), the length of the cable unwound from the cable drum and the length of the remaining cable are calculated and displayed on the display of the mobile device 70.

Therefore, the user's work efficiency is greatly improved through efficient length management of used and remaining cables in the process of untangling cables from the cable drum.

As another example, if you pre-enter the cable drum specifications (drum type, drum diameter, cable type, cable diameter, cable length, etc.) into the dedicated application and set the length of the cable to be released from the cable drum, In the process of the user pulling the cable and unwinding the cable, the length of the unwinding cable is automatically calculated, and when the cable is unwound by the length of the unwinding cable preset by the user, the operation of the pressure adjusting means 40 is automatically controlled to rotate the rotating plate 20. By stopping, the cable is released only to the length preset by the user, which further improves work efficiency using the cable.

As another example, if the specifications of the cable drum (drum type, drum diameter, cable type, cable diameter, cable length, etc.) are pre-entered into the dedicated application, the fixing plate (10) transmitted from the communication means (60) ) The tilt of the cable drum is calculated using the posture information and displayed on the display of the mobile device (70).

In addition, in the dedicated application, workable tilt values are pre-stored for each cable drum standard, so that the actual tilt value of the cable drum calculated using the posture information of the fixing plate 10 transmitted from the communication means 60 is pre-stored for work. If the possible inclination value is exceeded, the risk of safety accidents occurring during work increases, so work safety is improved by displaying a warning alarm using the display and speaker of the mobile device 70.
