Description

Technical Field

[0001] The present application relates to the technical field of cable trench cover construction, and in particular to a cable trench cover construction device. Background Art

[0002] A cable trench is an underground channel used to accommodate cables. The cable trench cover is used to cover the top of the cable trench to prevent debris outside the cable trench from entering the cable trench and causing damage to the cables in the cable trench, thereby ensuring the safe operation of the cables. The cables in the cable trench need to be inspected and maintained regularly to prevent safety accidents involving the cables. The first step in cable maintenance is to remove the cover on the cable trench.

[0041] See also Figure 1 to Figure 2An embodiment of the present application provides a cable trench cover construction device, including a support mechanism 100, a mounting seat 300, a winding mechanism 400, a first suspension arm 510, a second suspension arm 520, a first traction member 610 and a second traction member 620; the mounting seat 300 is arranged on the support mechanism 100 and can reciprocate along the first direction of the cable trench; the winding mechanism 400 is arranged on the mounting seat 300; one end of the first suspension arm 510 is arranged on one side of the mounting seat 300 along the second direction of the cable trench, and one end of the second suspension arm 520 is arranged on the other side of the mounting seat 300 along the second direction, the second direction is perpendicular to the first direction, and the first suspension arm A first winding member 530 is provided at one end of 510 away from the mounting seat 300, and a second winding member 540 is provided at one end of the second suspension arm 520 away from the mounting seat 300; one end of the first traction member 610 is provided on the winding mechanism 400, and the other end of the first traction member 610 bypasses the first winding member 530 and is used to connect with the cover plate 900; one end of the second traction member 620 is provided on the winding mechanism 400, and the other end of the second traction member 620 bypasses the second winding member 540 and is used to connect with the cover plate 900; the winding mechanism 400 can wind up or release the first traction member 610 and the second traction member 620 to lift or drop the cover plate 900.

[0042] When the cable trench cover construction device is used, the support mechanism 100 is first placed on the ground and straddles the cable trench along a first direction of the cable trench, and the end of the first traction member 610 away from the reeling mechanism 400 and the end of the second traction member 620 away from the reeling mechanism 400 are connected to the cable trench cover 900, and then the reeling mechanism 400 is controlled to reel in the first traction member 610 and the second traction member 620. At this time, the end of the first traction member 610 away from the reeling mechanism 400 that bypasses the first winding member 530 gradually approaches the first suspension arm 510, and the end of the second traction member 620 that bypasses the second winding member 540 gradually approaches the first suspension arm 510. The end of 20 away from the winding mechanism 400 gradually approaches the second boom 520 to lift the cover plate 900. Subsequently, the staff controls the mounting seat 300 to move along the first direction on the supporting mechanism 100, so that the first boom 510 and the second boom 520 drive the cover plate 900 to move, thereby driving the cover plate 900 away from the area above the cable trench. Compared with the conventional technology, the above-mentioned cable trench cover plate construction device can more conveniently move the cover plate 900 from above the cable trench to other areas, so as to facilitate the staff to inspect the cables in the cable trench and reduce the labor intensity of the staff.

[0043] For further information, see Figure 2After the cover plate 900 is moved from above the cable trench to other areas, the first traction member 610 and the second traction member 620 can be released by the reeling mechanism 400 to place the cover plate 900 on the ground, and then the cables in the cable trench can be inspected. In other embodiments, the first traction member 610 and the second traction member 620 can also be used to suspend the cover plate 900 in mid-air and inspect the cables. It can be flexibly selected according to the actual working conditions on site and is not specifically limited here.

[0044] Furthermore, the first suspension arm 510 and the second suspension arm 520 both extend along the second direction of the cable trench so as to more stably suspend the cover plate 900 on the cable trench.

[0045] As an explanation, in the above embodiment, the first direction of the cable trench is the width direction of the cable trench (i.e. Figure 1 The second direction of the cable trench is the length direction of the cable trench (i.e. Figure 1 E direction in the figure).

[0046] In one embodiment, the cable trench cover construction device also includes a guide mechanism 200, which is arranged on the support mechanism 100, and the mounting seat 300 is movably arranged on the guide mechanism 200. The guide mechanism 200 extends along the width direction of the cable trench so that the guide mechanism 200 can be set across the cable trench. The first suspension arm 510 and the second suspension arm 520 both extend along the length direction of the cable trench to lift the cover 900 on the cable trench more stably.

[0047] See also Figure 1 to Figure 2 In one embodiment, the support mechanism 100 includes a first support member and a second support member, and the first support member and the second support member are respectively disposed at opposite ends of the guide mechanism 200 along the first direction to stably support the guide mechanism 200.

[0048] Furthermore, the first support member and the second support member are both forked legs, and the structure is stable.

[0049] Furthermore, the first support member, the second support member and the guide mechanism 200 are all made of lightweight materials, such as aluminum alloy; without affecting the overall strength, the first support member and the second support member are provided with weight-reducing holes, thereby further reducing the overall weight of the cable trench cover construction device to facilitate carrying by staff.

[0050] In one embodiment, the guide mechanism 200 is provided with a guide rail extending along a first direction, and the mounting seat 300 cooperates with the guide rail and can reciprocate along the first direction.

[0051] Furthermore, the guide mechanism 200 is provided with a first driving member, which is drivingly connected to the mounting seat 300 and can drive the mounting seat 300 to reciprocate along the first direction.

[0052] See also Figure 1 and Figure 5 In one embodiment, the first winding member 530 includes a first winding wheel, and the second winding member 540 includes a second winding wheel, and the axial direction of the first winding wheel and the axial direction of the second winding wheel are both parallel to the first direction; in this way, when the winding mechanism 400 winds up or releases the first traction member 610 and the second traction member 620, the friction force exerted on the first traction member 610 and the second traction member 620 can be reduced, thereby increasing the service life of the first traction member 610 and the second traction member 620.

[0053] See also Figure 1 and Figure 5 In one embodiment, the first traction member 610 includes a first rope, and the second traction member 620 includes a second rope. The first rope and the second rope can be connected to the cover plate 900 through a hook, and the winding mechanism 400 can wind up or release the first rope and the second rope to lift or lower the cover plate 900.

[0054] Furthermore, a lifting hole for connecting with a lifting hook is usually reserved on the cover plate 900, so that the first rope and the second rope can lift the cover plate 900.

[0055] Optionally, the winding mechanism 400 may be a reel, a drum, etc., which is not specifically limited here.

[0056] Furthermore, the length of the first rope wound up in the winding mechanism 400 should be greater than the thickness of the cover plate 900 so that the cover plate 900 can be effectively lifted.

[0057] See also Figure 5 and Figure 6 In one embodiment, the winding mechanism 400 includes a rotating column 410 , one end of which is disposed on the mounting seat 300 , and one end of the first traction member 610 and one end of the second traction member 620 are both connected to the side wall of the rotating column 410 .

[0058] The rotating column 410 can rotate to wind the first traction member 610 and the second traction member 620 around the side wall of the rotating column 410, thereby realizing the winding and releasing of the first traction member 610 and the second traction member 620, with low implementation cost and reliable winding effect.

[0059] In one embodiment, the first boom 510 is further provided with a third winding member 550, and the fourth boom is further provided with a fourth winding member 560. The third winding member 550 is arranged at one end of the first boom 510 close to the mounting seat 300, and the first traction member 610 bypasses the first winding member 530. The fourth winding member 560 is arranged at one end of the second boom 520 close to the mounting seat 300, and the second traction member 620 bypasses the fourth winding member 560. In this way, when the rotating column 410 rotates and reels the first traction member 610 and the second traction member 620, it can prevent the first traction member 610 and the second traction member 620 from being offset and occupying a larger space, thereby improving the ease of use of the cable trench cover construction device.

[0060] Furthermore, the third winding member 550 includes a third winding wheel, and the fourth winding member 560 includes a fourth winding wheel. The axis direction of the third winding wheel and the axis direction of the fourth winding wheel are both parallel to the axis direction of the rotating column 410 .

[0061] In one embodiment, the winding mechanism 400 further includes a second driving member, which is disposed on the mounting seat 300 and is drivingly connected to the rotating column 410 , and is used to drive the rotating column 410 to rotate.

[0062] Furthermore, the second driving member is a driving motor.

[0063] See also Figure 5 and Figure 8 In one embodiment, the winding mechanism 400 also includes a first assembly rod 420 and a first assembly portion 421, one end of the first assembly rod 420 is arranged on the side wall of the rotating column 410, and at least two first assembly portions 421 are provided, and all the first assembly portions 421 are arranged on the first assembly rod 420 at intervals along the axial direction of the first assembly rod 420, and one end of the first traction member 610 is used to connect with one of the first assembly portions 421.

[0064] Since the length of the first traction member 610 is fixed, one end of the first traction member 610 is connected to different first assembly parts 421, so that the traction stroke of the first traction member 610 on the cover plate 900 can be adjusted; for example, one end of the first traction member 610 is connected to the first assembly part 421 close to the rotating column 410. At this time, the length of the portion of the first traction member 610 located between the first winding member 530 and the rotating column 410 becomes longer, and correspondingly, the length of the portion of the first traction member 610 located between the first winding member 530 and the cover plate 900 becomes shorter, thereby making the first traction member 610 on the cover plate 900 The traction stroke becomes shorter; for another example, one end of the first traction member 610 is connected to the first assembly portion 421 away from the rotating column 410. At this time, the length of the portion of the first traction member 610 located between the first winding member 530 and the rotating column 410 becomes shorter, and accordingly, the length of the portion of the first traction member 610 located between the first winding member 530 and the cover plate 900 will be lengthened, thereby increasing the length of the traction stroke of the first traction member 610 on the cover plate 900; with such a configuration, the traction stroke of the first traction member 610 on the cover plate 900 can be flexibly adjusted, so that the cable trench cover plate construction device can be suitable for more working conditions.

[0065] By way of explanation, since the cable trench is usually buried below the ground, there are differences in the distance between different cable trenches and the ground, which in turn leads to differences in the distance between the cable trench cover 900 and the first lifting arm 510 of different cable trenches; in the above embodiment, by connecting one end of the first traction member 610 to different first assembly parts 421, the traction stroke of the first traction member 610 on the cover 900 can be adjusted, so that the first traction member 610 can lift the cable trench cover 900 on different cable trenches, thereby improving the applicability of the cable trench cover 900 construction device.

[0066] See also Figure 5 and Figure 8 As an embodiment that can be implemented simultaneously with the above-mentioned embodiments, the winding mechanism 400 also includes a second assembly rod 430 and a second assembly portion 431, one end of the second assembly rod 430 is arranged on the side wall of the rotating column 410, and at least two second assembly portions 431 are provided, and all the second assembly portions 431 are arranged on the second assembly rod 430 at intervals along the axial direction of the second assembly rod 430, and one end of the second traction member 620 is used to be connected to one of the second assembly portions 431.

[0067] Similar to the first assembly rod 420 and the first assembly portion 421 , detailed description thereof will be omitted here.

[0068] Further, the first assembly rod 420 and the second assembly rod 430 are coaxially arranged.

[0069] In one embodiment, a hook is disposed at one end of the first traction member 610 and the second traction member 620 for connecting with the first assembly portion 421 and the second assembly portion 431 .

[0070] See also Figures 5 and 6 In one embodiment, the winding mechanism 400 also includes a holding rod 440, and the side wall of the rotating column 410 is provided with at least two third assembly parts 450, all of the third assembly parts 450 are arranged at intervals along the circumference of the rotating column 410, and one end of the holding rod 440 is used to connect with one of the third assembly parts 450.

[0071] The holding rod 440 can be connected to the third assembly part 450 on the side wall of the rotating column 410. In this way, the staff can rotate the rotating column 410 by holding the holding rod 440, which is a labor-saving process and has low implementation costs. At least two third assembly parts 450 are arranged at circumferential intervals along the rotating column 410. The rotation angle of the rotating column 410 is adjusted by connecting one end of the holding rod 440 to different third assembly parts 450, and then the rising height of the cable trench cover 900 is adjusted, so that the cable trench cover 900 is at a suitable height to facilitate the staff to inspect the cables in the cable trench.

[0072] According to the lever principle, the longer the gripping rod 440 is, the more labor is saved. In one embodiment, the length of the gripping rod 440 is 3.5 to 4.5 times the length of the first suspension arm 510 .

[0073] See also Figure 1 and Figure 5 In one embodiment, a gripping portion is further provided at one end of the gripping rod 440 away from the rotating column 410 for the staff to grip.

[0074] See also Figure 6 In one embodiment, the third assembly portion 450 is provided with an insertion groove 451 , and the insertion groove 451 is used to be inserted with one end of the holding rod 440 .

[0075] One end of the holding rod 440 can be plugged into the plug-in slot 451 of the third assembly portion 450 to achieve connection between the holding rod 440 and the third assembly portion 450 , and the connection effect is reliable and easy to assemble and disassemble.

[0076] See also Figure 1 In one embodiment, the first suspension arm 510 is provided with a positioning member 700 , and the positioning member 700 is used to position and cooperate with the holding rod 440 .

[0077] When the holding rod 440 rotates to the positioning member 700, the positioning member 700 can be positioned and cooperated with the holding rod 440 to limit the holding rod 440 from continuing to rotate. In this way, when the staff controls the holding rod 440 to rotate to lift the cover 900, the positioning member 700 can limit the rotation of the holding rod 440 to continue to lift the cover 900, which is convenient for driving the cover 900 to move through the mounting seat 300. The implementation process is convenient and highly safe.

[0078] See also Figure 3 to Figure 4 In one embodiment, the positioning member 700 includes a first positioning portion 710, a second positioning portion 720 and a positioning pin 730. The first positioning portion 710 and the second positioning portion 720 are spaced apart along the axial direction of the rotating column 410. The first positioning portion 710, the first suspension arm 510 and the second positioning portion 720 are surrounded to form a positioning groove 740. The positioning groove 740 is used to accommodate the holding rod 440. The first positioning portion 710 is provided with a positioning through hole 711. The positioning pin 730 is penetrated through the positioning through hole 711 and can reciprocate along the axial direction of the positioning through hole 711, so that the positioning pin 730 can open or close the notch of the positioning groove 740.

[0079] When the holding rod 440 is rotated into the positioning groove 740, the positioning pin 730 is moved and the notch of the positioning groove 740 is closed. At this time, the side wall of the positioning pin 730 abuts against the holding rod 440 in the positioning groove 740, thereby preventing the holding rod 440 from falling out of the positioning groove 740, so as to continuously lift the cover plate 900, thereby facilitating driving the cover plate 900 away from the area above the cable trench; after the cable maintenance is completed, the positioning pin 730 is moved and the notch of the positioning groove 740 is opened, and then the holding rod 440 is removed from the positioning groove 740, and the cover plate 900 is lowered to seal the cable trench; with such a configuration, the implementation cost is low and the positioning effect of the holding rod 440 is reliable.

[0080] See also Figure 3 to Figure 4 In one embodiment, the positioning pin 730 includes a pull ring 731, a first limit plate 732, a second limit plate 733 and a pin body. The first limit plate 732 and the second limit plate 733 are respectively arranged at the opposite ends of the pin body. The pull ring 731 is arranged on the first limit plate 732. The pin body is penetrated by the positioning through hole 711 and can reciprocate along the axial direction of the positioning through hole 711. The diameter of the first limit plate 732 and the diameter of the second fiberboard are both larger than the aperture of the positioning through hole 711 to prevent the positioning pin 730 from detaching.

[0081] Furthermore, the second positioning portion 720 defines a receiving groove 721 , and the receiving groove 721 is used to accommodate the second limiting plate 733 .

[0082] In addition, in other embodiments, at least two positioning members 700 are provided, wherein one positioning member 700 is provided on the first boom 510 and the other positioning member 700 is provided on the second boom 520.
