[0025] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Example 1

[0027] like Figure 1 As shown, the right end of the tightening assembly 1 is fixedly connected to a steel wire rope 18, the right end of the steel wire rope 18 is fixedly connected to a hook 19, the outer side wall of the hook 19 is sleeved with a fixing belt 20, and the outer side wall of the fixing belt 20 is fixedly connected to a positioning fixture 21;

[0028] Before use, the positioning fixing part 21 is embedded and fixed in the ground, so that the connection between the fixing belt 20 and the hook 19 can prevent the tightening component 1 from moving when the geogrid is tightened. After that, the geogrid can be tightened by operating the tightening component 1.

[0029] like Figure 1 , Figure 2 and Figure 4 As shown, a control chamber 24 is integrally formed inside the tightening assembly 1 and on the right side of the winding chamber 3. A rotating rod 25 is rotatably connected to the rear surface of the control chamber 24 via a rotating shaft. The front end of the control chamber 24 extends to the front of the tightening assembly 1 and is fixedly connected to an operating handle 26. A bevel gear 27 is fixedly connected to the rear of the outer wall of the rotating rod 25. A rotating rod 28 is rotatably connected to the left side of the winding chamber 3 via a rotating shaft. The right end of the rotating rod 28 extends to the inside of the control chamber 24. The outer wall of the bevel gear 1 27 is meshed with the outer wall of the bevel gear 29, the outer wall of the rotating rod 28 is fixedly connected with a worm 30 located inside the winding chamber 3, the upper part of the outer wall of the take-up reel 4 is fixedly connected with a worm wheel 31, the worm 30 is meshed with the worm wheel 31, the left end of the cable 5 passes through the cleaning chamber 7 and extends to the left side of the cleaning box 2, and is fixedly connected with a steel wire rope 22, and the left end of the steel wire rope 22 is fixedly connected with a hook 23;

[0030] When the device passes through the positioning fixture 21, it is fixedly connected to the corresponding connection point on the geogrid through the set wire rope 22 and hook 23. Then the operator holds the operating handle 26 and starts to rotate. The rotation of the operating handle 26 drives the rotating rod 1 25 to rotate around its rotation axis. Since the bevel gear 1 27 on the rotating rod 1 25 is meshed with the bevel gear 29 on the rotating rod 28, the rotational motion of the bevel gear 1 27 is transmitted to the bevel gear 29, and the rotating rod 28 is rotated together. The rotation of the rotating rod 28 drives the worm 30 to rotate, and the worm 30 is meshed with the bevel gear 29 on the take-up drum 4. The worm wheel 31 is meshed, so the rotational motion of the worm 30 is converted into the rotational motion of the worm wheel 31, thereby driving the take-up drum 4 to start rotating. As the take-up drum 4 rotates, the cable 5 is gradually wound around the take-up drum 4. The tightening of the cable 5 will pull the hook 23 to apply tension to the geogrid, so that the geogrid moves in the direction of the tightening component 1, thereby achieving the purpose of tightening the geogrid. At the same time, due to the self-locking property of the worm 30 and the worm wheel 31, when the operating handle 2 26 stops turning, the take-up drum 4 will also maintain its current position, thereby maintaining the tension of the cable 5 and maintaining the geogrid in a tensioned state.

[0031] like Figure 1 and Figure 2 As shown, the front surface of the operating handle 26 is fixedly connected with a non-slip grip 32;

[0032] When the operating handle 26 is used to tighten the geogrid, the operator needs to continuously apply a certain force. The shape and material of the non-slip handle 32 can better fit the hand, disperse the hand pressure, and reduce hand fatigue caused by long-term operation.

[0033] like Figure 1-Figure 4 As shown, a geogrid tensioning device is provided, including a tightening component 1, a cleaning box 2 is fixedly connected to the left side of the tightening component 1, a winding chamber 3 is integrally formed on the left side of the interior of the tightening component 1, a wire reel 4 is rotatably connected to the inner lower surface and the inner upper surface of the winding chamber 3 through a rotating shaft, a cable 5 is sleeved on the outer wall of the wire reel 4, two connecting plates 6 are fixedly connected to the lower surface of the cleaning box 2, a cleaning chamber 7 is integrally formed in the interior of the cleaning box 2, a moving plate 8 is symmetrically slidably connected to the interior of the cleaning chamber 7, a cleaning sponge 9 is detachably connected to the opposite sides of the two moving plates 8, a pushing chamber 10 is integrally formed in the interior of the cleaning box 2 and located in front and rear of the cleaning chamber 7, a through-type sliding groove 11 is provided on the inner lower surface of the two pushing chambers 10, and the inner lower surfaces of the two pushing chambers 10 are provided with The two ends of the two sliding plates 12 are slidably connected with a sliding plate 12, an operating handle 13 is arranged in front of the connecting plate 6 located in front of the cleaning box 2, a bidirectional threaded rod 14 is fixedly connected at the center of the rear surface of the operating handle 13, the rear end of the bidirectional threaded rod 14 is rotatably connected to the front surface of the connecting plate 6 located behind the cleaning box 2 through a rotating shaft, the outer side wall of the bidirectional threaded rod 14 is symmetrically threadedly connected with a connecting block 15, the top ends of the two connecting blocks 15 respectively pass through the two sliding grooves 11, and are respectively fixedly connected to the lower surfaces of the two sliding plates 12, the opposite sides of the two sliding plates 12 are fixedly connected with a push rod 16, the opposite ends of the two push rods 16 extend to the inside of the cleaning chamber 7, and are fixedly connected with a contact plate 17, and the opposite sides of the two contact plates 17 are respectively in contact with the opposite sides of the two moving plates 8;

[0034] When the geogrid is tightened by rotating the operating handle 26 to reel in the cable 5, the operator can hold the operating handle 13 and start to rotate it. The rotation of the operating handle 13 drives the bidirectional threaded rod 14 to rotate, and the two connecting blocks 15 can be controlled to move relative to each other through the rotation of the bidirectional threaded rod 14. When the two connecting blocks 15 move, they will drive the two sliding plates 12 to slide along the two sliding grooves 11 in the two pushing chambers 10. The movement of the two sliding plates 12 pushes the two contact plates 17 through the two push rods 16, and the two contact plates 17 further push the two moving plates 8. The two moving plates 8 move relative to each other in the cleaning chamber 7 under the action of the two contact plates 17, thereby driving the two cleaning sponges 9 to move relative to each other, so that the surface of the cable 5 can be in close contact. In the process of continuous winding and movement of the cable 5, the two cleaning sponges 9 wipe the outer surface of the cable 5 to remove dust, impurities, etc. attached to the surface of the cable 5, thereby increasing the service life of the cable 5.

[0035] like Figure 3 and Figure 5As shown, a cover plate 33 is arranged above the inner wall of the cleaning chamber 7, and a movable groove 34 is symmetrically provided on the lower surface of the cover plate 33, and the inner front surface and the inner rear surface of the two movable grooves 34 are fixedly connected with a guide rod 35, and the outer side walls of the two guide rods 35 are slidably connected with sliding blocks 36, and the lower surfaces of the two sliding blocks 36 are respectively fixedly connected to the upper surfaces of the two movable plates 8, and the outer side walls of the two guide rods 35 are sleeved with springs 37, and the two ends of the two springs 37 are respectively fixedly connected to the opposite sides of the two sliding blocks 36 and the inner opposite sides of the two movable grooves 34, and a square groove 38 is provided on the upper surface of the cover plate 33, and a pull plate 39 is symmetrically slidably connected to the inner lower surface of the square groove 38, and the opposite sides of the two pull plates 39 are fixedly connected with a clamping plate 40, and the upper left side and the upper right side of the cleaning chamber 7 are provided with fixed grooves 41, and the opposite sides of the two clamping plates 40 extend to the inside of the two fixed grooves 41 respectively;

[0036] The operator puts the fingers of both hands into the square groove 38, grabs the two pull plates 39 respectively, and then pulls the two pull plates 39 inward at the same time. The movement of the two pull plates 39 drives the two card plates 40 to disengage from the two fixed grooves 41, releasing the locking state of the cover plate 33 and the cleaning chamber 7. Then, the cover plate 33 is carefully lifted upward, which can drive the two cleaning sponges 9 and the two movable plates 8 to rise together. At this time, the two cleaning sponges 9 can be easily accessed, and the operator can clean or replace the two cleaning sponges 9, thereby improving the cleaning quality of the cable 5. After the operation is completed, the cover plate 33 is reinserted into the interior of the cleaning chamber 7, and then the two pull plates 39 are pulled at the same time to make the two card plates 40 snap into the interior of the two fixed grooves 41, so as to complete the installation of the cover plate 33, thereby improving the maintainability of the device.

[0037] like Figure 3 As shown, the inner left side and the inner right side of the square groove 38 are fixedly connected with a plurality of guide rods 42, the outer side walls of the plurality of guide rods 42 are respectively slidably connected with the two pull plates 39, the outer side walls of the plurality of guide rods 42 are sleeved with springs 43, and the two ends of the plurality of springs 43 are respectively fixedly connected with the opposite sides of the two pull plates 39;

[0038] By setting up multiple guide rods 42, it can be ensured that the card plate 40 can be accurately removed from or inserted into the fixing groove 41, avoiding deviation or shaking of the pull plate 39 during operation, thereby ensuring smooth removal and installation of the cover plate 33. By setting up multiple springs 43, when installing the cover plate 33, the elastic force of the multiple springs 43 can easily and quickly align the card plate 40 with the fixing groove 41, thereby improving the comfort and accuracy of the operation.

[0039] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
