Description

Technical Field

[0001] This invention belongs to the field of power transmission cable protection technology, specifically relating to a power transmission line suspension distance limiting device. Background Technology

[0002] Currently, when large equipment such as cranes, excavators, concrete mixer trucks, pump trucks, ships, and dredgers pass under power transmission cables, the lack of warning signs and the dark color of the cables make them easy for operators to overlook. This leads to a failure to adjust the height of protruding parts of the equipment, such as the crane boom, excavator bucket, and dredger lifting device, in a timely manner. This can cause these protruding parts to come into contact with the power transmission cables, potentially leading to electrical discharge accidents, or to snag or cut the cables, causing power outages or tripping. Therefore, a power transmission line suspension distance limiting device is needed to address the technical challenges facing operators of large equipment. This is because such devices lack warning signs and are often dark in color, making it difficult to detect and adjust the height of protruding parts.

[0003] Publication (Announcement) No.: CN111224345B discloses a power transmission cable suspension distance limiting device, relating to the field of power transmission cable protection technology. It includes an insulated suspension mechanism and an insulated distance limiting rod. The insulated suspension mechanism includes a base, a first support plate, a second support plate, and a suspension plate. The lower ends of both the first and second support plates are connected to the base. One end of the suspension plate is hinged to the upper end of the first support plate. The end of the suspension plate away from the first support plate is fixed to the second support plate via a suspension plate fixing member. Both ends of the insulated distance limiting rod are connected to the base via insulated connecting rods. This invention allows operators of large equipment to notice the power transmission cable, enabling them to adjust the height of any protruding parts of the equipment in a timely manner. This prevents the protruding parts of the equipment from approaching the power transmission cable and causing a discharge accident, and also prevents the protruding parts of the equipment from hooking or cutting the power transmission cable, thus avoiding tripping or power outages. However, the technical solution in the aforementioned patent document has unstable mounting and is impractical. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a power transmission line suspension distance limiting device, which solves the problems mentioned in the background art.

[0005] The objective of this invention is achieved as follows: A power transmission line suspension distance limiting device includes a left connector and a right connector. A left control component and a right control component are respectively disposed inside the left and right connectors. The left control component includes a left connecting rod, and the right control component includes a right connecting rod. The lower ends of the left and right connecting rods are fixedly connected by a crossbar. A left vertical cylinder is fixedly connected to the lower end of the left connector, and a right vertical cylinder is fixedly connected to the lower end of the right connector. The lower ends of the left and right vertical cylinders are fixedly connected by a horizontal plate. A docking component is fixedly disposed at the front end of the horizontal plate, and a display component is fixedly disposed at the rear end of the horizontal plate. In use, the operator stands on the ground and engages the upper end of the insulated operating rod with the docking component to lift the left and right connectors upwards and connect them to the power transmission line. The operation is simple, the connection is stable, and it is highly practical. The display component serves to alert passing vehicles to the presence of a power transmission line, preventing vehicles from excessively raising themselves and pulling on the power line. By fixing a crossbar to the lower end of the left and right connecting rods, when the operator works, pulling the crossbar downwards can simultaneously move the left and right connecting rods, thus achieving synchronous movement of the left and right connecting rods and enabling the left and right connecting parts to clamp and fix the power transmission line synchronously.

[0006] Furthermore, the left connector includes a left base plate, the front end of the left base plate is rotatably connected to an upwardly extending left front chuck, the rear end of the left base plate is rotatably connected to an upwardly extending left rear chuck, the inner wall of the left front chuck is provided with a left front sliding groove, the inner wall of the left rear chuck is provided with a left rear sliding groove, the front end of the left control member is slidably connected to the left front sliding groove, and the rear end of the left control member is slidably connected to the left rear sliding groove. The left control component includes a left rear slide block and a left front slide block. The left rear slide block is slidably connected inside the left rear slide groove, and the left front slide block is slidably connected inside the left front slide groove. A left spring is fixedly connected to the inner wall of the left rear slide block, and the other end of the left spring is fixedly connected to the inner wall of the left front slide block. A left auxiliary block is fixedly disposed in the middle of the left spring. The upper end of the left connecting rod is fixedly connected to the lower surface of the left auxiliary block. A left through hole is opened on the surface of the left base plate, and the left vertical cylinder is connected to the left through hole. The lower end of the left connecting rod passes through the left through hole and the interior of the left vertical cylinder, and the left connecting rod is slidably engaged with the inner wall of the left through hole and the left vertical cylinder. The lower end of the left connecting rod extends partially below the left vertical cylinder.

[0007] In use, pull the left connecting rod downwards. The left connecting rod moves downwards, causing the left auxiliary block to move downwards as well. At this time, the left spring moves downwards and is compressed simultaneously. As the left spring moves downwards, the upper ends of the left front clamp and left rear clamp open. After the upper ends of the left front clamp and left rear clamp open, they clamp onto the outside of the power transmission line, so that the left connector is engaged with the power transmission line. After engagement, the operator releases the downward pulling force of the left connecting rod. Under the restoring force of the left spring, the left connecting rod moves upwards to reset, realizing the automatic clamping of the left front clamp and left rear clamp. The power transmission line is stably and firmly fixed inside the left connector.

[0008] Furthermore, the right connector includes a right base plate, the front end of the right base plate is rotatably connected to an upwardly extending right front chuck, the rear end of the right base plate is rotatably connected to an upwardly extending right rear chuck, the inner wall of the right front chuck is provided with a right front sliding groove, the inner wall of the right rear chuck is provided with a right rear sliding groove, the front end of the right control member is slidably connected to the right front sliding groove, and the rear end of the right control member is slidably connected to the right rear sliding groove. The right control component includes a right rear slide block and a right front slide block. The right rear slide block is slidably connected inside the right rear slide groove, and the right front slide block is slidably connected inside the right front slide groove. A right spring is fixedly connected to the inner wall of the right rear slide block, and the other end of the right spring is fixedly connected to the inner wall of the right front slide block. A right auxiliary block is fixedly disposed in the middle of the right spring. The upper end of the right connecting rod is fixedly connected to the lower surface of the right auxiliary block. A right through hole is opened on the surface of the right base plate, and the right vertical cylinder is connected to the right through hole. The lower end of the right connecting rod passes through the right through hole and the interior of the right vertical cylinder, and the right connecting rod is slidably engaged with the inner wall of the right through hole and the right vertical cylinder. The lower end of the right connecting rod extends partially below the right vertical cylinder.

[0009] In use, pull the right connecting rod downwards. The downward movement of the right connecting rod causes the right auxiliary block to move downwards as well. Simultaneously, the right spring moves downwards and is compressed. As the right spring moves downwards, the upper ends of the right front and right rear clamps open, clamping against the outside of the power line. This engages the right connector with the power line. After engagement, the operator releases the downward pull on the right connecting rod. Under the restoring force of the right spring, the right connecting rod moves upwards to reset, automatically clamping the right front and right rear clamps. The power line is securely and stably fixed inside the right connector. Through the cooperation of the left and right connectors, they clamp against the outside of the power line from both sides, ensuring the display component is stably attached below the power line.

[0010] Furthermore, the left front clamp, left rear clamp, right front clamp, and right rear clamp all include an upper plate section and a lower plate section. The inner sidewall of the upper plate section of the left front clamp, left rear clamp, right front clamp, and right rear clamp are all fixedly provided with multiple soft rubber protrusions. The soft rubber protrusions are used to increase the friction. With the setting of the soft rubber protrusions, after the left connector and right connector clamp and fix the power transmission line, the soft rubber protrusions can increase the friction between the power transmission line and the left connector and right connector, thereby making the connection more stable.

[0011] Furthermore, the docking assembly includes a left and a right support ear fixedly connected to the front end of the horizontal plate. An arc-shaped bracket is fixedly disposed between the left and right support ears. The bracket has a left and right limiting slotted hole for facilitating docking of the insulating operating rod. The display assembly includes an auxiliary plate detachably connected to the rear end of the horizontal plate. A display plate is fixedly disposed on the lower surface of the auxiliary plate, and an electronic control device is fixedly disposed on the lower surface of the auxiliary plate. A rechargeable lithium battery is disposed inside the electronic control device, and a downlight electrically connected to the electronic control device is fixedly disposed on the lower surface of the auxiliary plate. The display plate can be engraved with lettering. The downlight is used to make the display plate and the engraved lettering on it more visible to the driver at night.

[0012] The beneficial effects of this invention are as follows: Operators standing on the ground can easily connect the left and right connecting parts to the power transmission line by engaging the upper end of the insulated operating rod with the docking assembly. This simple operation ensures stable connection and high practicality. The display component serves to alert passing vehicles to the presence of the power transmission line, preventing vehicles from pulling on it due to excessive height. By fixing a crossbar to the lower end of the left and right connecting rods, operators can simultaneously move the left and right connecting rods by pulling down the crossbar, thus achieving synchronous movement and simultaneously clamping and fixing the power transmission line with the left and right connecting parts. In use, pull the left connecting rod downwards. The left connecting rod moves downwards, causing the left auxiliary block to move downwards as well. At this time, the left spring moves downwards and is compressed simultaneously. As the left spring moves downwards, the upper ends of the left front clamp and left rear clamp open. After the upper ends of the left front clamp and left rear clamp open, they clamp onto the outside of the power transmission line, so that the left connector is engaged with the power transmission line. After engagement, the operator releases the downward pulling force of the left connecting rod. Under the restoring force of the left spring, the left connecting rod moves upwards to reset, realizing the automatic clamping of the left front clamp and left rear clamp. The power transmission line is stably and firmly fixed inside the left connector. Pull the right connecting rod downwards, causing it to move downwards and pulling the right auxiliary block downwards. At this time, the right spring moves downwards and is compressed simultaneously. As the right spring moves downwards, the upper ends of the right front clamp and right rear clamp open. After the upper ends of the right front clamp and right rear clamp open, they clamp onto the outside of the power transmission line, making the right connector engage with the power transmission line. After engagement, the operator releases the downward pulling force of the right connecting rod. Under the restoring force of the right spring, the right connecting rod moves upwards to reset, realizing the automatic clamping of the right front clamp and right rear clamp. The power transmission line is stably and firmly fixed inside the right connector.

[0013] The left and right connectors work together to clamp the power transmission line from both sides, ensuring the display assembly is stably attached below it. The display panel can be engraved with lettering, and recessed lights ensure visibility for drivers at night, making the engraved lettering on the panel more prominent. The soft rubber protrusions increase friction between the power transmission line and the connectors after they are clamped and secured, resulting in a more stable connection.
