Description

Technical Field

[0001] The utility model relates to the technical field of movable ballast robots, in particular to a movable ballast trolley rope retraction sensor which can be used underwater for a long time. Background Art

[0002] When the salt field automatic movable slag robot is operating, there will be a problem of entanglement of plastic thatch ropes. Therefore, the movable slag rake needs to be able to automatically lift when encountering the rope, that is, a sensor is needed to sense the plastic thatch rope. The sensor perception needs to be stable and reliable. Once a fault occurs, it may cause the movable slag rake to damage the rope.

[0003] Since the active slag rake is used in seawater, general sensors are prone to malfunction due to salt spray, especially under conditions of seawater splashing or infiltration. Therefore, it is necessary to develop a new type of sensor that can avoid malfunction caused by seawater erosion and is stable and reliable.

[0004] Therefore, a rope-retracting sensor for a movable ballast trolley which can be used underwater for a long time is proposed. Utility Model Content

[0006] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0007] A rope retraction sensor for a movable ballast trolley that can be used underwater for a long time includes a movable ballast rake body, a basic mounting frame is installed on the surface of the movable ballast rake body via fixing bolts, a non-contact sensor is installed on one side wall of the basic mounting frame, a rope retraction sensor is fixedly installed on the other side wall of the basic mounting frame, a U-shaped fixing frame is fixedly installed on the other side wall of the basic mounting frame, and a trigger rod is hingedly installed on the other side wall of the basic mounting frame and one side inner wall of the U-shaped fixing frame.

[0008] Furthermore, the movable slag rake body includes a frame, and multiple groups of rake bodies are fixedly installed on the bottom surface of the frame. The multiple groups of rake bodies are arranged in an equidistant array on the bottom surface of the frame. A vertical frame is fixedly installed on the top surface of the frame, and a mounting side frame is fixedly installed on the top of the frame and the inner top of the vertical frame. A basic mounting frame is fixedly installed on one side wall of the mounting side frame by fixing bolts.

[0009] Furthermore, the rope retraction sensor includes an elastic device, the elastic device is fixedly installed on the other side wall of the basic mounting frame, a limit column and a reverse limit column are fixedly installed on the other side wall of the basic mounting frame, and a protective shell is fixedly installed on the other side wall of the basic mounting frame.

[0010] Furthermore, a through hole is provided on the surface of the basic mounting frame, and the through hole on the surface of the basic mounting frame and the non-contact sensor are arranged correspondingly.

[0011] Furthermore, the non-contact sensor adopts a Hall sensor, and the surface of the non-contact sensor is sealed by a sealant.

[0012] Furthermore, the top of the trigger rod is bent, and the limiting column and the reverse limiting column are respectively located on the front and rear sides of the trigger rod.

[0013] The beneficial effects of the utility model are as follows:

[0014] By installing the basic mounting frame on the movable slag rake body, the trigger rod is hingedly installed on the other side wall of the basic mounting frame through the U-shaped fixing frame, and a pre-tightening force is applied to the trigger rod through the elastic part of the rope retraction sensor. The pre-tightening force is opposite to the installation direction caused by the rope tensioning force.

When the trigger rod is rotated to the trigger position of the non-contact sensor under force, the non-contact sensor collects a signal and commands the movable slag rake body to lift upward. The non-contact sensor uses a Hall sensor with a certain detection distance, which can avoid water leakage caused by the action of conventional sensor contacts. The surface of the non-contact sensor is sealed with glue and can be immersed in water. In addition, the non-contact sensor is installed laterally to avoid problems such as false triggering of signals caused by uncertain detection distance. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] like Figures 1 to 4As shown, a rope retraction sensor for an active ballast trolley that can be used underwater for a long time includes an active ballast rake body 1. A basic mounting frame 2 is installed on the surface of the active ballast rake body 1 through fixing bolts. A non-contact sensor 3 is installed on one side wall of the basic mounting frame 2. A rope retraction sensor 4 is fixedly installed on the other side wall of the basic mounting frame 2. A U-shaped fixing frame 5 is fixedly installed on the other side wall of the basic mounting frame 2, and a trigger rod 6 is hingedly installed on the other side wall of the basic mounting frame 2 and the inner wall of one side of the U-shaped fixing frame 5. More specifically, the basic mounting frame 2 is installed on the movable slag rake body 1, and the trigger rod 6 is hingedly installed on the other side wall of the basic mounting frame 2 through the U-shaped fixing frame 5. The elastic part of the rope retraction sensor 4 applies a pre-tightening force to the trigger rod 6. The pre-tightening force is opposite to the installation direction caused by the rope tension. The limiting part of the rope retraction sensor 4 conflicts with it to resist the torsional force of the elastic part of the rope retraction sensor 4 to avoid overshoot. The limiting part of the rope retraction sensor 4 is used to avoid excessive rope tension and damage to the elastic part of the rope retraction sensor 4. The non-contact sensor 3 is installed on one side wall of the basic mounting frame 2. When the trigger rod 6 is rotated to the trigger position of the non-contact sensor 3 under force, the non-contact sensor 3 collects a signal and commands the movable slag rake body 1 to lift upward.

[0025] The movable slag rake body 1 includes a frame 101, on the bottom surface of which multiple groups of rake bodies 102 are fixedly mounted. The multiple groups of rake bodies 102 are arranged in an equidistant array on the bottom surface of the frame 101. A vertical frame 103 is fixedly mounted on the top surface of the frame 101. A mounting side frame 104 is fixedly mounted on the top of the frame 101 and the inner top of the vertical frame 103. A side wall of the mounting side frame 104 is fixedly mounted with a base mounting frame 2 via fixing bolts. More specifically, the frame 101 and the vertical frame 103 enable connection with the movable slag trolley, the rake bodies 102 on the bottom surface of the frame 101 enable turning and cleaning of the salt pan, and the mounting side frame 104 allows the base mounting frame 2 to be fixedly mounted via fixing bolts.

[0026] The rope retraction sensor 4 includes an elastic device 401. The elastic device 401 is fixedly mounted on the other side wall of the base mounting frame 2. A limit column 402 and a reverse limit column 403 are fixedly mounted on the other side wall of the base mounting frame 2. A protective shell 404 is fixedly mounted on the other side wall of the base mounting frame 2. More specifically, a preload is applied by the elastic device 401. The preload is opposite to the installation direction caused by the rope tension. The reverse limit column 403 contacts the limit column 402 to resist the torsional force of the elastic device 401 and avoid overshoot. The elastic device 401 is used to prevent excessive rope tension from damaging the elastic device 401. The protective shell 404 further protects the elastic device 401, the limit column 402, and the reverse limit column 403.

[0027] The surface of the base mounting frame 2 is provided with a through hole, and the through hole on the surface of the base mounting frame 2 is correspondingly arranged with the non-contact sensor 3. More specifically, the through hole on the surface of the base mounting frame 2 enables the non-contact sensor 3 to monitor the trigger rod 6.

[0028] The contactless sensor 3 uses a Hall effect sensor, and its surface is sealed with sealant. More specifically, the use of a Hall effect sensor in the contactless sensor 3 provides a certain detection distance, preventing water leakage caused by the contact elements of conventional sensors. The sealant on the contactless sensor 3 allows it to be immersed in water. Furthermore, the sideways mounting of the contactless sensor 3 prevents problems such as false triggering of signals due to uncertain detection distance.

[0029] The top of the trigger lever 6 is bent, and the limiting post 402 and the reverse limiting post 403 are respectively located at the front and rear sides of the trigger lever 6. More specifically, the top of the trigger lever 6 has a certain bending angle, which allows the rope to retreat better.

[0030] In summary: by installing the basic mounting frame 2 on the movable slag rake body 1, the trigger rod 6 is hingedly installed on the other side wall of the basic mounting frame 2 through the U-shaped fixing frame 5, and a pre-tightening force is applied to the trigger rod 6 through the elastic part of the rope retraction sensor 4. The pre-tightening force is opposite to the installation direction caused by the rope tension. The limiting part of the rope retraction sensor 4 conflicts with it to resist the torsional force of the elastic part of the rope retraction sensor 4 to avoid overshoot. The limiting part of the rope retraction sensor 4 is used to avoid excessive rope tension and damage to the elastic part of the rope retraction sensor 4. The non-contact sensor 3 is installed on one side wall of the basic mounting frame 2. When the trigger rod 6 is rotated to the trigger position of the non-contact sensor 3 under force, the non-contact sensor 3 collects a signal and commands the movable slag rake body 1 to lift upward.
