Schematic grounding pulley

Fig. 1-2 illustrate a ground block for suspending and grounding a wire.

Specifically, the ground tackle includes a frame body 10, and the frame body 10 includes a bottom plate 11 and two side plates 12, wherein the side plates 12 extend from two ends of the bottom plate 11 and form a guiding channel 101.

Further, the frame body 10 further includes a connecting plate 13, and the connecting plate 13 is fixedly connected to the side plate 12.

Specifically, the ground tackle further includes a conductive member 20, and the conductive member 20 is fixedly connected to the connecting plate 13, so that the current in the wire is transmitted to the conductive member 20, and the current flow direction is controlled. It should be noted that the conductive member 20 is also connected to an external ground so that the current in the wire is grounded, thereby preventing the current in the wire from harming the operator.

Further, the conductive assembly 20 includes two rolling members 21 and two first conductive elements 22, the rolling members 21 are rotatably mounted on the connecting plate 13, wherein the first conductive elements 22 are mounted on the connecting plate 13, so that the current in the wires flows to the first conductive elements 22. In addition, the first conductive element 22 is also connected to an external ground. It should be understood by those skilled in the art that the first conductive element 22 is implemented as a conductive carbon brush, and the type of embodiment of the first conductive element 22 is not a focus of the present invention, and the present invention is not limited in this respect. It is worth mentioning that, in order to ensure the good conductivity, the frame body 10 is made of metal, so that the current in the wire flows to the first conductive element 22 through the rolling member 21 and then to the ground wire connected to the first conductive element 22.

In view of the fact that no grounding point may be encountered during the operation, so that the grounding trolley cannot be grounded, and further the construction progress is delayed, and the operation efficiency is low, improvement is needed.

Further, the conductive assembly 20 further comprises at least a second conductive element 23, the second conductive element 23 is mounted on the side plate 12, wherein the second conductive element 23 is further connected to an external ground line, so that the current in the wires flows to the conductive element.

Further, the ground tackle also includes a ground peg 30, and the ground peg 30 is detachably connected to one end of the bottom plate 11. It is worth mentioning that the grounding piles 30 are detachably mounted on the bottom plate 11 when the grounding trolley can be connected to a ground point of the ground. When the ground surface has no ground point, which causes the ground tackle to be unable to be grounded, the ground peg 30 can be removed from one end of the bottom plate 11, and the ground peg 30 is inserted into the ground surface, and the depth of the ground peg 30 inserted into the ground surface is greater than 600mm, so that the current in the lead can flow to the ground peg 30, thereby preventing the ground tackle from being effectively connected to the ground surface because the ground peg 30 is inserted too shallow, and further preventing the current in the lead from hurting operators.

Specifically, the ground tackle further comprises a lifting assembly 40, wherein the lifting assembly 40 is arranged on the frame body 10 and controls the feeding of the wire in a manner of moving up and down, so that the ground tackle is tightly hung on the wire, and the ground tackle is prevented from falling off the wire. It is worth mentioning that when the ground block encounters the wires with different cross-sectional diameters, the lifting assembly 40 is controllably moved by a predetermined distance to control the distance between the lifting assembly 40 and the wires, so that the ground block is tightly attached to the wires, thereby making the ground block more convenient to use.

Further, the lifting assembly 40 includes a moving rod 41, a moving block 42 and a tension member 43, the tension member 43 is rotatably connected to the moving block 42, and the moving block 42 is located in the guiding passage 101. It is worth mentioning that the tensioning member 43 is mounted on the moving block 42, and the moving block 42 is located in the guiding channel 101, thereby limiting the tensioning member 43 between the two rolling members 21, wherein the height of the tensioning member 43 from the bottom plate 11 is less than the height of the rolling members 21 from the bottom plate 11, and the tensioning member 43 is parallel to the rolling members 21. Further, the moving rod 41 is connected to the bottom plate 11 in a vertically movable manner, wherein the moving rod 41 is also fixedly connected to the moving block 42. Further, the moving rod 41 is controllably moved a predetermined distance to control the distance of the tension member 43 from the rolling member 21, thereby confining the wire between the tension member 43 and the rolling member 21.

Further, the lifting assembly 40 further includes an elastic member 44 installed on the moving rod 41, wherein one end of the elastic member 44 is connected to the bottom plate 11, and the other end is connected to the moving block 42. It should be noted that when the moving rod 41 is pulled by an external force to move downward, the moving rod 41 drives the moving block 42 to move downward, and the elastic member 44 is deformed by the pressure of the moving block 42. Further, when the moving block 42 is displaced downward, the distance between the tension member 43 and the rolling member 21 is continuously enlarged. When the distance between the tension member 43 and the rolling member 21 is greater than the diameter of the cross section of the conductive wire, the conductive wire is located between the rolling member 21 and the tension member 43, at this time, the moving rod 41 is not affected by external force and is displaced downward, and the moving block 42 is displaced downward, so that the elastic member 44 is in a compressed state. When the moving rod 41 is not subjected to an external force, due to the elastic deformation of the elastic member 44, the elastic member 44 applies an upward force to the moving block 42, so that the elastic member 44 pushes the moving block 42 to displace upward, so that the tensioning member 43 displaces upward. It is worth mentioning that when the tension member 43 touches the surface of the wire, the moving block 42 will drive the tension member 43 to move upward due to the elastic deformation of the elastic member 44. At this time, the wire is pressed by the tension member 43 to be bent downward. Because the ground tackle hangs on the wire through two rolling pieces 21, when the tensioning piece 43 moves upwards, the wire is bent and is driven to be attached to the two rolling pieces 21, and then the wire is tensioned, so that the ground tackle is tightly hung on the wire, and the ground tackle is prevented from falling off from the wire. Further, the elastic member is implemented as a spring, wherein the spring is not the focus of the present invention, and the present invention is not limited in this respect.

Further, the moving block 42 has a pressing surface 421, and the pressing surface 421 is connected to the elastic member 44 and is acted by the gravity of the tensioning member 43, so that the elastic member 44 is deformed under the action of the gravity, and the center distance between the tensioning member 43 and the rolling member 21 is controlled, so that the conducting wire is located between the tensioning member 43 and the rolling member 21. When the moving rod 41 moves the tension member 43 to a predetermined distance, an improvement is made to prevent the tension member 43 from moving downward due to the gravity.

Further, the lifting assembly 40 further includes a limiting member 46, wherein the limiting member 46 is screwed to the moving rod 41 and abuts against the bottom of the bottom plate 11 to limit the displacement of the moving rod 41, and further to limit the distance between the tensioning member 43 and the rolling member 21, so as to control the degree of tightness of the wires at the surface joint of the rolling member 21 and the tensioning member 43.

It is worth mentioning that the moving block 42 moves up and down in the guide passage 101, in view of the fact that the tensioning member 43 is mounted on the moving block 42, and the tensioning member 43 is not mounted in the middle of the moving block 42. Therefore, when the ground block is suspended on the wire, since the moving block 42 does not perform the left-right limitation, the lifting assembly 40 may be inclined to the left and then shaken, so that the ground block may be separated from the wire. Therefore, improvements are needed.

Further, the moving block 42 has a limiting end 422, the limiting end 422 directly contacts with the surfaces of the two side plates 12, and the width of the limiting end 422 is greater than that of the guide channel 101, so as to prevent the moving block 42 from moving leftward, thereby enhancing the stability of the lifting assembly 40.

Further, the side plate 12 has two grooves 121. Further, when the position-limiting end 422 is located in the groove 121, the width of the position-limiting end 422 is consistent with the width of the groove 121. Therefore, the position-limiting end 422 can slide along the groove 121, thereby facilitating the detachment of the lifting assembly 40.

Further, the lifting assembly 40 further includes a pull ring 45, and the pull ring 45 is mounted at one end of the moving rod 41. It is worth mentioning that when the lifting assembly 40 needs to be moved downward, the pull ring 45 is manually pulled by a person, so that the moving rod 41 is moved downward.

In conclusion, the grounding trolley based on the embodiment of the application is clarified, and the grounding trolley has the advantages of convenience in use, difficulty in shaking, simple structure and the like.

It is worth mentioning that in the embodiment of the present application, the ground block has a simple structure, does not involve a complicated manufacturing process and expensive materials, and has high economical efficiency. Simultaneously, to the manufacture factory, the ground connection coaster that this application provided is easily produced, and low cost, more is favorable to controlling manufacturing cost, further is favorable to the product to promote and use.

It will be understood by those skilled in the art that the embodiments of the present invention as described above and shown in the drawings are given by way of example only and are not limiting of the present invention. The objects of the present invention have been fully and effectively accomplished. The functional and structural principles of the present invention have been shown and described in the embodiments, and any variations or modifications may be made without departing from the principles of the present invention.
