Description

Technical Field

[0001] The utility model relates to the technical field of loop steel ropes, in particular to a vertical loop steel rope anti-off-track device. Background Technique

[0002] Currently, an anti-off-track pressure roller attached to the steel rope is installed on one side of a loop winch, and a pressure roller sensor is installed at the end of the pressure roller. When the steel rope is not wound along the guide groove on the winch drum, the steel rope will be higher than normal, and the anti-off-track pressure roller attached to the steel rope will be lifted. When the pressure roller sensor does not detect a signal, the loop will alarm and remind.

[0003] However, this anti-off-track device only monitors the steel rope that runs out of the guide groove on the drum and cannot effectively monitor the loose winding of the drum steel rope. Most production lines also use laser pair-shooting devices at the position where the steel rope travels, but they cannot monitor the off-track at the winch and other positions. As a result, the detection is not comprehensive enough, which may cause the steel rope on the winch to be misaligned and is not convenient for use. In view of this, we introduce a vertical loop steel rope anti-off-track device. Content of the Utility Model

[0004] The purpose of the utility model is to provide a vertical loop steel rope anti-off-track device to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A vertical loop steel rope anti-off-track device, comprising: a steel rope drum and a trolley;

[0006] The surface of the steel rope drum is wound with a steel rope. The setting of the steel rope drum allows the steel rope to be wound. An anti-off-track pressure roller is arranged on one side of the steel rope drum. The anti-off-track pressure roller is convenient for restricting the steel rope. The steel rope is wound on the surface of the anti-off-track pressure roller. A fixed pulley is connected to the surface of the steel rope. Multiple groups of fixed pulleys are arranged, and the fixed pulleys are connected to the surface of an object. The top of the trolley is connected to the bottom of the steel rope. The steel rope is convenient for driving the trolley to move. A limiting vertical plate is arranged below the trolley. A sensor structure for detecting that the trolley descends to the limit position is arranged on one side of the limiting vertical plate below the trolley.

[0007] Preferably, the sensor structure includes a pressure sensor protection cover. On both sides of the top of the pressure sensor protection cover, there are slider brackets connected. The number of the slider brackets is two groups. Between the two groups of slider brackets, there is a contact slider component connected, and the contact slider component is located above the pressure sensor protection cover. When the bottom of the trolley contacts the contact slider component, the contact slider component will be pressed down, so that the contact slider component moves downward. The bottom of the contact slider component extends into the pressure sensor protection cover and is connected with a pressure sensor. Inside the pressure sensor protection cover and below the pressure sensor, there is a pressure sensor stop block horizontally arranged. After the contact slider component drives the pressure sensor to move downward, it will contact the pressure sensor stop block, thereby controlling the trolley to continue moving downward. A spring is sleeved on the surface of the contact slider component and is located on the top of the pressure sensor protection cover. After the contact slider component moves downward, it will squeeze the spring, and the spring will also drive the contact slider component to move upward to return to the initial position.

[0008] Preferably, one side of the sensor structure is connected to a PCL control system through wire harness A, and one end of the PCL control system is connected to a control panel through wire harness B.

[0009] Preferably, a roller sensor is connected to one side of the anti-derailment groove roller, and the roller sensor is used to detect whether the steel wire rope on the surface of the anti-derailment groove roller is disengaged.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] (1) The bottom of the trolley first contacts the contact slider component on the surface of the sensor structure. The contact slider component will drive the pressure sensor to move, and the spring on the surface of the contact slider component will be squeezed. When the trolley reaches the limit position, the pressure sensor just contacts the pressure sensor stop block, triggers a signal, and feeds it back to the PLC control system to execute the winch stop order. In the normal state, the pressure sensor is inside the pressure sensor protection cover to form a protection, and the risk of false shutdown and line stop caused by foreign objects falling and personnel accidentally touching and sensing can be avoided.

[0012] (2) Through this monitoring method, it is more comprehensive and will not have the situation where only the misalignment of the steel wire rope on the winch could be detected before.

[0013] (3) By controlling the actual position of the trolley, it will not continue to move after the trolley descends to the designated position due to incorrect position calculation, resulting in the steel wire rope derailing.

[0014] (4) It can avoid human operation errors. After descending to the limit position, the sensor structure will automatically stop the operation instruction to protect the steel wire rope.

[0015] (5) The modification amount is small, the device is simple, and the investment in the modification price is low. Description of the Drawings

Specific embodiments

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figure 1-2 , the present utility model provides a technical solution: a vertical loop wire rope anti - derailing device, comprising: a wire rope reel 1 and a trolley 5. A wire rope 6 is wound on the surface of the wire rope reel 1. An anti - derailing groove pressure roller 2 is arranged on one side of the wire rope reel 1. The wire rope 6 is wound on the surface of the anti - derailing groove pressure roller 2. A fixed pulley 7 is connected to the surface of the wire rope 6 and is connected to the surface of an object. The top of the trolley 5 is connected to the bottom of the wire rope 6. A limiting vertical plate 4 is arranged below the trolley 5. A sensor structure 8 for detecting that the trolley 5 descends to the limit position is arranged on one side of the limiting vertical plate 4 below the trolley 5.

[0021] The sensor structure 8 includes a pressure sensor protective cover 86, and slider brackets 82 are connected to both sides of the top of the pressure sensor protective cover 86. There are two groups of slider brackets 82, and a contact slider component 81 is connected between the two groups of slider brackets 82. The contact slider component 81 is located above the pressure sensor protective cover 86. When the bottom of the trolley 5 contacts the contact slider component 81, the contact slider component 81 will be pressed down, thereby moving the contact slider component 81 downward. The bottom of the contact slider component 81 extends to the inside of the pressure sensor protective cover 86 and is connected to the pressure sensor. The pressure sensor 84 is provided with a pressure-sensitive stopper 85 connected to the interior of the pressure-sensor protective cover 86 and located below the pressure sensor 84. The pressure-sensitive stopper 85 is arranged horizontally. After the contact slider component 81 drives the pressure sensor 84 to move downward, it will contact the pressure-sensitive stopper 85, thereby controlling the vehicle 5 to continue to move downward. The surface of the contact slider component 81 is provided with a spring 83 located on the top of the pressure-sensor protective cover 86. After the contact slider component 81 moves downward, it will squeeze the spring 83, and the spring 83 will also drive the contact slider component 81 to move upward and return to its initial position.

[0022] One side of the sensor structure 8 is connected to a PCL control system 9 via a wiring harness A, and one end of the PCL control system is connected to a control panel 10 via a wiring harness B.

[0023] A roller sensor 3 is connected to one side of the anti-slip groove roller 2 , and the roller sensor 3 is used to detect whether the steel wire rope 6 on the surface of the anti-slip groove roller 2 is detached.

[0024] Specifically, when using, as follows Figure 1 As shown, when the trolley 5 is lowered, the wire rope drum 1 rotates counterclockwise during operation. When the trolley 5 is lowered to the lowest position, the wire rope 6 on the wire rope drum 1 must be retained for more than three turns to ensure the safety of the equipment.

[0025] When the trolley 5 descends to the limit position, the bottom of the trolley 5 first contacts the contact slider component 81 on the surface of the sensor structure 8, and the contact slider component 81 drives the pressure sensor 84 to move, and the spring 83 on the surface of the contact slider component 81 will be squeezed. When the trolley 5 has completed the limit position, the pressure sensor 84 just contacts the pressure-sensitive stopper 85, triggering a signal, which is fed back to the PLC control system 9 to execute the winch stop command. Under normal conditions, the pressure sensor 84 is inside the pressure sensor protection cover 86 to protect it, and there will be no risk of foreign objects falling or people accidentally sensing contact, which will cause the risk of accidental shutdown of the machine and line.

[0026] The monitoring and detection is more comprehensive, and there will be no misalignment of the wire rope 6 on the winch;

[0027] By controlling the actual position of the trolley 5, it is possible to prevent the trolley 5 from continuing to move after descending in place due to incorrect position calculation, and to keep the wire rope 6 out of the inner groove of the wire rope reel 1;

[0028] Human operation errors can be avoided. After descending to the limit position, the sensor structure 8 will automatically stop the operation instruction to protect the wire rope 6;

[0029] The amount of modification is small, the device is simple, and the investment in the modification cost is low.

[0030] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
