Description

Technical Field

[0001] The utility model relates to the technical field of cable manufacturing, in particular to a cable take-up rack anti-rolling device. Background Art

[0002] The cable reel currently used in the cable industry only provides basic cable reeling and unwinding functions, requiring operators to assist in the work next to the high-speed rotating equipment. Since the equipment rotates at a high speed when the cable is reeled in or unwinding, the operator needs to get close to the reel and constantly adjust the direction of the cable when arranging the cables. In this process, there is a risk of arms or clothing being caught. Once this happens, the operator will rotate rapidly with the reel, causing disability at the least, or even death at the worst. There have been many such cases in China, which seriously endanger people's personal safety.

[0003] The Chinese utility model with the authorization announcement number CN 205862884 U discloses a cable retractable rack that can automatically stop running in an emergency, including a frame, a retractable device installed on the frame, and detection modules respectively arranged on both sides of the frame, and a control switch for controlling the detection module to start, and a control module connected to the detection module; the retractable device includes a retractable device; the detection module detects that a human body is approaching and sends a stop signal to the control module, and the control module brakes the retractable device. When a human body approaches the retractable rack and a danger may occur, the control module will receive the command of the detection module and quickly cut off the power supply of the retractable drive mechanism to stop it from running. At the same time, the electric push rod auxiliary brake unit assists in braking the retractable reel to ensure that the retractable reel stops running quickly, brakes the retractable device, and prevents the operator from being drawn into the retractable device, thereby avoiding personal injury to the operator as much as possible.

[0004] In the above solution, a detection module such as a human body microwave induction sensor is used to detect whether a human body is approaching, and then the start and stop of the device are controlled by a control module. The reliability is low and the misjudgment rate is high. Utility Model Content

[0005] The purpose of the utility model is to propose a cable take-up rack anti-rolling device to address the deficiencies of the prior art, which can more accurately determine the occurrence of accidents, so that the cable take-up rack can be shut down in time, effectively avoiding personal injury to operators and improving safety performance.

[0006] The technical solution to achieve the purpose of this utility model is:

[0007] An anti-entanglement device for a cable take-up rack, comprising a pair of columns fixedly arranged perpendicular to the ground and a take-up rack bar erected on the tops of the two columns. At least one upper end of the column is fixedly installed with a support and a limit switch. The support is elastically connected to the take-up rack bar in the horizontal direction, so that the take-up rack bar is in movable contact with the top of the column. The limit switch is signal-connected to the cable take-up rack and the sensing end is in contact with the take-up rack bar, so that when the take-up rack bar moves under an external force, the limit switch is triggered to control the cable take-up rack to stop.

[0008] Further, the support includes a fixed block and a side plate vertically and fixedly installed on one side of the fixed block. The other side of the fixed block is fixedly connected to the column, and a spring is connected between the side plate and the take-up rack bar.

[0009] Further, a guiding mechanism is arranged between the side plate and the take-up rack bar along the telescopic direction of the spring.

[0010] Further, the guiding mechanism includes a screw rod vertically and fixedly installed on the take-up rack bar in the horizontal direction. The screw rod is coaxially arranged with the spring and penetrates through the side plate, and a limit nut is arranged at the other end of the screw rod.

[0011] Further, the support and the limit switch are respectively arranged on both sides of the take-up rack bar.

[0012] Further, a first baffle is fixedly arranged at the top of the column on the same side as the limit switch, and the limit switch and the first baffle are arranged in a vertical dislocation manner.

[0013] Further, the support and the limit switch are arranged on the same side of the take-up rack bar and are longitudinally dislocated.

[0014] Further, a second baffle vertically and fixedly installed on the top of the column is arranged on the other side of the take-up rack bar.

[0015] Adopting the above technical solution, the utility model has the following beneficial effects:

[0016] (1) The utility model forms a blocking structure through the column and the take-up rack bar, which is placed between the operator and the cable take-up and pay-off rack. At the same time, the elastic connection between the support and the take-up rack bar realizes the movable installation of the take-up rack bar on the top of the column. When the operator touches the high-speed rotating take-up disc and has a tendency to be involved, the take-up rack bar will surely be touched, so that the take-up rack bar moves under an external force. At this time, the limit switch with the sensing end in contact with the take-up rack bar is triggered, and a signal is sent to the cable take-up rack to stop working. Compared with the existing human body microwave induction sensor, it can more accurately judge the occurrence of an accident, make the cable take-up rack stop in time, effectively avoid personal injury to the operator, and improve the safety performance.

[0017] (2) The utility model realizes the elastic connection between the support and the wire take-up rack bar through a spring, with a simple structure and low manufacturing cost.

[0018] (3) A guiding mechanism is additionally provided between the support and the wire take-up rack bar of the utility model to prevent the wire take-up rack bar from being unable to fully reset due to the bending deformation of the spring, which affects the normal use of the limit switch.

[0019] (4) The guiding mechanism of the utility model adopts a screw rod, with a simple structure. At the same time, it can be used in cooperation with a limit nut to adjust the distance between the wire take-up rack bar and the side plate, ensuring the constant position of the wire take-up rack bar, thereby improving the induction sensitivity of the limit switch.

[0020] (5) The utility model provides two different installation positions for the limit switch to meet different on-site installation requirements, and provides a solution for adding a baffle to improve the stability of the wire take-up rack bar placed on the column. Description of the Drawings

[0031] To better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings of the specification and specific implementation manners.

[0032] (Example 1)

[0033] As Figures 1 to 3 shown in the cable take-up rack anti-entanglement device, which includes a column 1, a take-up rack stop bar 2, a limit switch 3 and a support 4. Among them, there are two columns 1, both of which are fixedly arranged perpendicular to the ground. The take-up rack stop bar 2 is erected on the tops of the two columns to form a stop rack structure, which is placed between the operator and the cable take-up and pay-off rack. The limit switch 3 and the support 4 are respectively arranged on both sides of the take-up rack stop bar 2 and are fixedly installed at the upper end of the column 1. And the support 4 is elastically connected to the take-up rack stop bar 2 in the horizontal direction, realizing the movable installation of the take-up rack stop bar 2 on the top of the column 1. The limit switch 3 is signal-connected to the cable take-up rack and the sensing end is in contact with the take-up rack stop bar 2. When the operator touches the high-speed rotating take-up disc and has a tendency to be involved, it will inevitably touch the take-up rack stop bar 2, causing the take-up rack stop bar 2 to move under an external force. At this time, the limit switch 3 is triggered, and thus a signal is sent to the cable take-up rack to make it stop working. Compared with the existing human body microwave induction sensor, the mechanical trigger mechanism of this embodiment can more accurately judge the occurrence of an accident, enabling the cable take-up rack to stop in time, effectively avoiding personal injury to the operator and improving safety performance.

[0034] Specifically, the support 4 includes a fixed block 4-1 and a side plate 4-2 vertically and fixedly installed on one side of the fixed block 4-1. The other side of the fixed block 4-1 is fixedly connected to the column, and a spring 5 is connected between the side plate 4-2 and the take-up rack stop bar 2, thus realizing the elastic connection between the support 4 and the take-up rack stop bar 2, with a simple structure and low manufacturing cost.

[0035] In order to prevent the spring 5 from bending and deforming during the extrusion process by the take-up rack stop bar 2, a guiding mechanism is connected between the side plate and the take-up rack stop bar 2 along the spring telescopic direction in this embodiment. The guiding mechanism includes a screw rod 6 vertically and fixedly installed on the take-up rack stop bar 2 in the horizontal direction. The screw rod 6 is coaxially arranged with the spring 5 and penetrates through the side plate 4-2 with a gap. A limit nut 7 is provided at the other end of the screw rod 6, which can not only prevent the spring 5 from bending and deforming, resulting in the take-up rack stop bar 2 being unable to fully reset, ensuring the normal use of the limit switch 3, but also adjusting the distance between the take-up rack stop bar 2 and the side plate by rotating the limit nut 7 to ensure the constant position of the take-up rack stop bar 2, thereby improving the sensing sensitivity of the limit switch 3.

[0036] (Example 2)

[0037] The structure of this embodiment is similar to that of Example 1, the difference being that as Figure 4 and Figure 5As shown, a first baffle 8 is fixedly provided at the top of the vertical column 1 and the limit switch 3 on the same side. At this time, the limit switch 3 and the first baffle 8 are arranged offset in the vertical direction to ensure that the sensing end of the limit switch 3 can contact the wire take-up frame bar 2. The first baffle 8 limits the side of the wire take-up frame bar 2 away from the support 4, improving the stability of the wire take-up frame bar 2 placed on the vertical column 1.

[0038] (Embodiment 3)

[0039] The structure of this embodiment is similar to that of Embodiment 1, except that as Figure 6 shown, the support 4 and the limit switch 3 are arranged on the same side of the wire take-up frame bar 2 and are offset longitudinally to meet different on-site installation requirements.

[0040] (Embodiment 4)

[0041] The structure of this embodiment is similar to that of Embodiment 3, except that as Figure 7 shown, a second baffle 9 vertically fixedly installed at the top of the vertical column is provided on the side of the wire take-up frame bar 2 away from the support 4. The first baffle 8 limits the side of the wire take-up frame bar 2 away from the support 4, improving the stability of the wire take-up frame bar 2 placed on the vertical column 1.

[0042] The utility model forms a blocking frame structure through the vertical column 1 and the wire take-up frame bar 2, which is placed between the operator and the cable winding and unwinding frame. At the same time, the wire take-up frame bar 2 is movably installed at the top of the vertical column 1 through the elastic connection between the support 4 and the wire take-up frame bar 2. When the operator touches the high-speed rotating wire take-up disc and has a tendency to be involved, the wire take-up frame bar 2 will surely be touched, causing the wire take-up frame bar 2 to move under the external force. At this time, the limit switch 3 whose sensing end contacts the wire take-up frame bar 2 is triggered, and then a signal is sent to the cable take-up frame to stop working. Compared with the existing human body microwave induction sensor, it can more accurately judge the occurrence of an accident, cause the cable take-up frame to stop in time, effectively avoid personal injury to the operator, and improve the safety performance. At the same time, multiple installation schemes of the limit switch 3 are provided to meet different on-site installation requirements.

[0043] In the above specific embodiments, the purpose, technical solution, and beneficial effects of the utility model are further described in detail. It should be understood that the above are only specific embodiments of the utility model and are not used to limit the utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
