Description

Technical Field

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

[0002] A cable trench is an underground channel used to house cables. Cable trench covers are used to cover the cable trench to prevent debris from outside the trench from entering and damaging the cables inside, thus ensuring the safe operation of the cables. The cables inside the cable trench need to be inspected regularly to prevent cable safety accidents, and the first step in cable inspection is to remove the covers from the cable trench.

[0003] In traditional techniques, workers need to move the cover plate from the cable trench, which results in high labor intensity for the workers. Summary of the Invention

[0004] Therefore, it is necessary to provide a cable trench cover construction device to address the problem that traditional technologies require workers to move the cover plates from the cable trench, resulting in high labor intensity for workers.

[0005] The technical solution is as follows:

[0006] One embodiment provides a cable trench cover construction device, comprising:

[0007] Supporting institutions;

[0008] Mounting base, the mounting base being disposed on the support mechanism and capable of reciprocating along a first direction of the cable trench;

[0009] A winding mechanism, wherein the winding mechanism is disposed on the mounting base;

[0035] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0036] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0037] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0038] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0039] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0040] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0041] Please see Figures 1 to 2One embodiment of this application provides a cable trench cover construction device, including a support mechanism 100, a mounting base 300, a winding mechanism 400, a first boom 510, a second boom 520, a first traction member 610, and a second traction member 620; the mounting base 300 is disposed on the support mechanism 100 and is capable of reciprocating along a first direction of the cable trench; the winding mechanism 400 is disposed on the mounting base 300; one end of the first boom 510 is disposed on one side of the mounting base 300 along a second direction of the cable trench, and one end of the second boom 520 is disposed on the other side of the mounting base 300 along the second direction, the second direction being perpendicular to the first direction, the first boom... The first winding member 530 is provided at the end of the second boom 520 away from the mounting base 300, and the second winding member 540 is provided at the end of the second boom 520 away from the mounting base 300. One end of the first traction member 610 is provided at the winding mechanism 400, and the other end of the first traction member 610 passes around 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 at the winding mechanism 400, and the other end of the second traction member 620 passes around 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 lower the cover plate 900.

[0042] In use, the aforementioned cable trench cover construction device involves first placing the support mechanism 100 on the ground and crossing the cable trench in the first direction. Then, the ends of the first traction member 610 and the second traction member 620, located away from the winding mechanism 400, are connected to the cable trench cover 900. Next, the winding mechanism 400 is controlled to wind up the first traction member 610 and the second traction member 620. At this time, the end of the first traction member 610, which passes around the first winding member 530, gradually approaches the first boom 510, and the end of the second traction member 620, which passes around the second winding member 540, gradually approaches the first boom 510. The end of the cable trench cover plate 900 away from the winding mechanism 400 gradually approaches the second boom 520, lifting the cover plate 900. Then, the operator controls the mounting base 300 to move along the first direction on the support mechanism 100, so that the first boom 510 and the second boom 520 drive the cover plate 900 to move, thereby moving the cover plate 900 away from the area above the cable trench. Compared with traditional 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 that the operator can inspect the cables in the cable trench and reduce the labor intensity of the operator.

[0043] Further, please refer to Figure 2After the cover plate 900 is moved from above the cable trench to another area, the first traction member 610 and the second traction member 620 can be released using the winding 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 cover plate 900 can also be suspended in mid-air using the first traction member 610 and the second traction member 620 and the cables can be inspected. The choice can be made flexibly according to the actual working conditions on site, and no specific limitation is made here.

[0044] Furthermore, both the first boom 510 and the second boom 520 extend along the second direction of the cable trench to more stably lift the cover plate 900 on the cable trench.

[0045] For illustrative purposes, in the above embodiments, 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., the direction of direction D in the cable trench). Figure 1 (in the E direction).

[0046] In one embodiment, the cable trench cover construction device further includes a guide mechanism 200, which is disposed on the support mechanism 100. The mounting base 300 is movably disposed 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 boom 510 and the second boom 520 both extend along the length direction of the cable trench so as to lift the cover 900 on the cable trench more stably.

[0047] Please see Figures 1 to 2 In one embodiment, the support mechanism 100 includes a first support member and a second support member, which are respectively disposed at opposite ends of the guide mechanism 200 along a first direction to provide stable support for the guide mechanism 200.

[0048] Furthermore, both the first and second support members are bifurcated legs, ensuring structural stability.

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

[0050] In one embodiment, the guide mechanism 200 is provided with a guide rail extending in a first direction, and the mounting base 300 is guided and engaged with the guide rail and is capable of reciprocating along the first direction.

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

[0052] Please see 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. The axial directions of the first winding wheel and the second winding wheel are both parallel to the first direction. With this configuration, when the winding mechanism 400 winds up or releases the first traction member 610 and the second traction member 620, the frictional force on the first traction member 610 and the second traction member 620 can be reduced, thereby improving the service life of the first traction member 610 and the second traction member 620.

[0053] Please see 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 via hooks. 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, the cover plate 900 is usually provided with lifting holes for connecting to the hook, so that the first rope and the second rope can lift the cover plate 900.

[0055] Optionally, the winding mechanism 400 can be a roll, reel, etc., without specific limitations.

[0056] Furthermore, the length of the first rope winding 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] Please see 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 base 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 unwinding of the first traction member 610 and the second traction member 620. The implementation cost is low and the winding effect is reliable.

[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 located at one end of the first boom 510 near the mounting base 300, and the first traction member 610 passes around the first winding member 530. The fourth winding member 560 is located at one end of the second boom 520 near the mounting base 300, and the second traction member 620 passes around the fourth winding member 560. In this way, when the rotating column 410 rotates and retracts the first traction member 610 and the second traction member 620, it can prevent the positions of the first traction member 610 and the second traction member 620 from shifting and occupying more 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 axial directions of the third winding wheel and the fourth winding wheel are both parallel to the axial 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 base 300 and drivenly connected to the rotating column 410. The second driving member is used to drive the rotating column 410 to rotate.

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

[0063] Please see Figure 5 and Figure 8 In one embodiment, the winding mechanism 400 further includes a first mounting rod 420 and a first mounting part 421. One end of the first mounting rod 420 is disposed on the side wall of the rotating column 410. At least two first mounting parts 421 are provided. All the first mounting parts 421 are spaced apart on the first mounting rod 420 along the axial direction of the first mounting rod 420. One end of the first traction member 610 is used to connect with one of the first mounting parts 421.

[0064] Since the length of the first traction member 610 is fixed, connecting one end of the first traction member 610 to different first assembly parts 421 allows for adjustment of the traction stroke of the first traction member 610 on the cover plate 900. For example, connecting one end of the first traction member 610 to a first assembly part 421 near the rotating column 410 increases the length of the portion of the first traction member 610 located between the first winding member 530 and the rotating column 410, and correspondingly shortens the length of the portion of the first traction member 610 located between the first winding member 530 and the cover plate 900, thereby increasing the traction stroke of the first traction member 610 on the cover plate 900. The traction stroke is shortened; for example, one end of the first traction member 610 is connected to the first assembly part 421 away from the rotating column 410. In this case, the length of the part of the first traction member 610 located between the first winding member 530 and the rotating column 410 is shortened. Correspondingly, the length of the part of the first traction member 610 located between the first winding member 530 and the cover plate 900 will be lengthened, thereby increasing the traction stroke of the first traction member 610 on the cover plate 900. With this setting, the traction stroke of the first traction member 610 on the cover plate 900 can be flexibly adjusted, so that the cable trench cover construction device can be applied to more working conditions.

[0065] As an explanation, since cable trenches are usually buried underground, the distance between different cable trenches and the ground surface varies, which in turn leads to differences in the distance between the cable trench cover 900 and the first boom 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] Please see Figure 5 and Figure 8 As an embodiment that can be implemented simultaneously with the above embodiments, the winding mechanism 400 further includes a second assembly rod 430 and a second assembly part 431. One end of the second assembly rod 430 is provided on the side wall of the rotating column 410. At least two second assembly parts 431 are provided. All the second assembly parts 431 are spaced apart on the second assembly rod 430 along the axial direction of the second assembly rod 430. One end of the second traction member 620 is used to connect with one of the second assembly parts 431.

[0067] Similar to the first assembly rod 420 and the first assembly part 421, they will not be described again here.

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

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

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

[0071] The gripping rod 440 can be connected to the third assembly part 450 on the side wall of the rotating column 410. In this way, the operator can rotate the rotating column 410 by gripping the gripping rod 440, which is labor-saving and low in implementation cost. At least two third assembly parts 450 are arranged circumferentially around the rotating column 410. By connecting one end of the gripping rod 440 to different third assembly parts 450, the rotation angle of the rotating column 410 can be adjusted, thereby adjusting the rising height of the cable trench cover 900 so that the cable trench cover 900 is at a suitable height, so that the operator can inspect the cables in the cable trench.

[0072] According to the lever principle, the longer the grip rod 440 is, the less effort is required. In one embodiment, the length of the grip rod 440 is 3.5 to 4.5 times the length of the first boom 510.

[0073] Please see Figure 1 and Figure 5 In one embodiment, the end of the gripping rod 440 away from the rotating column 410 is also provided with a gripping part so that the staff can grip it.

[0074] Please see Figure 6 In one embodiment, the third assembly part 450 is provided with a plug groove 451 for plugging into one end of the grip rod 440.

[0075] One end of the grip rod 440 can be inserted into the insertion slot 451 of the third assembly part 450 to realize the connection between the grip rod 440 and the third assembly part 450. The connection effect is reliable and easy to disassemble and assemble.

[0076] Please see Figure 1 In one embodiment, the first boom 510 is provided with a positioning element 700, which is used to position and engage with the grip rod 440.

[0077] When the gripping rod 440 rotates to the positioning member 700, the positioning member 700 can engage with the gripping rod 440 to restrict the gripping rod 440 from continuing to rotate. Thus, when the operator controls the gripping rod 440 to rotate in order to lift the cover plate 900, the positioning member 700 can restrict the rotation of the gripping rod 440 to continuously lift the cover plate 900, making it easy to move the cover plate 900 through the mounting base 300. The implementation process is convenient and highly safe.

[0078] Please see Figures 3 to 4 In one embodiment, the positioning member 700 includes a first positioning part 710, a second positioning part 720, and a positioning pin 730. The first positioning part 710 and the second positioning part 720 are spaced apart along the axial direction of the rotating column 410. The first positioning part 710, the first boom 510, and the second positioning part 720 surround each other to form a positioning groove 740. The positioning groove 740 is used to accommodate the gripping rod 440. The first positioning part 710 is provided with a positioning through hole 711. The positioning pin 730 passes 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 opening of the positioning groove 740.

[0079] After the gripping rod 440 rotates into the positioning groove 740, the positioning pin 730 is moved and the opening of the positioning groove 740 is closed. At this time, the side wall of the positioning pin 730 abuts against the gripping rod 440 in the positioning groove 740, thereby preventing the gripping rod 440 from coming out of the positioning groove 740, so as to continuously lift the cover plate 900, thereby facilitating the movement of 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 opening of the positioning groove 740 is opened. Then the gripping rod 440 is moved out of the positioning groove 740, the cover plate 900 is lowered and the cable trench is sealed. This setting has low implementation cost and reliable positioning effect of the gripping rod 440.

[0080] Please see Figures 3 to 4 In one embodiment, the positioning pin 730 includes a pull ring 731, a first limiting plate 732, a second limiting plate 733, and a pin body. The first limiting plate 732 and the second limiting plate 733 are respectively disposed at opposite ends of the pin body. The pull ring 731 is disposed on the first limiting plate 732. The pin body passes through the positioning through hole 711 and can reciprocate along the axial direction of the positioning through hole 711. The diameter of the first limiting plate 732 and the diameter of the second fiberboard are both larger than the hole diameter of the positioning through hole 711 to prevent the positioning pin 730 from dislodging.

[0081] Furthermore, the second positioning part 720 is provided with a receiving groove 721, which is used to accommodate the second limiting plate 733.

[0082] As a supplement, in other embodiments, at least two positioning members 700 are provided, one of which is located on the first boom 510 and the other is located on the second boom 520. In this way, the holding rod 440 can be positioned with the positioning member 700 regardless of whether it rotates clockwise or counterclockwise, making the operation of the cable trench cover construction device more convenient.

[0083] Please see Figures 5 to 9 In one embodiment, the mounting base 300 is provided with an installation channel 310, the inner wall of the installation channel 310 is provided with a guide seat 320, the guide seat 320 is provided with a guide wheel 330, and the cable trench cover construction device also includes a guide mechanism 200, the guide mechanism 200 includes a guide post 210, the guide post 210 passes through the installation channel 310 and is provided with a guide channel 211, the side wall of the guide post 210 is provided with a guide opening 212 communicating with the guide channel 211, the guide channel 211 and the guide opening 212 both extend along a first direction, the guide seat 320 passes through the guide opening 212, and the guide wheel 330 is located in the guide channel 211 and rolls with the side wall of the guide channel 211.

[0084] The guide post 210 passes through the mounting channel 310 of the mounting base 300. The inner wall of the mounting channel 310 is provided with a guide seat 320. The guide seat 320 passes through the guide opening 212 of the guide post 210, so that the guide wheel 330 on the guide seat 320 is set in the guide channel 211. The guide wheel 330 rolls with the side wall of the guide channel 211, so that the mounting base 300 can reciprocate along the first direction on the guide post 210. The movement process is stable and reliable.

[0085] Furthermore, by passing the guide seat 320 through the guide opening 212 and enabling the guide wheel 330 to roll into contact with the side wall of the guide channel 211, the guide wheel 330 can be prevented from falling off the guide opening 212, thereby further improving the movement stability of the mounting base 300.

[0086] In one embodiment, the length of the guide post 210 is 2.2-2.5 times the width of the cover plate 900. This allows the guide post 210 to be reduced in length while ensuring the effective movement of the cover plate 900, thereby reducing the overall weight and making it easier to carry.

[0087] Please see Figure 6 and Figure 9 In one embodiment, the mounting base 300 is provided with a first roller 341 on one side along the first direction, and a second roller 342 on the other side along the first direction. The axis of the first roller 341 and the axis of the second roller 342 are both perpendicular to the second direction. The first roller 341 and the second roller 342 are both in rolling engagement with the outer wall of the guide post 210.

[0088] The first roller 341 and the second roller 342 are respectively disposed on opposite sides of the mounting base 300 along the first direction. This prevents the mounting base 300 from swaying when it moves on the guide post 210, making the movement of the mounting base 300 on the guide post 210 more stable.

[0089] Further, please refer to Figure 6 , Figure 8 and Figure 9 The guide post 210 is a quadrangular prism. The guide opening 212 is opened on the side wall of the guide post 210 facing the ground (hereinafter referred to as the guide side wall). The guide seat 320 passes through the guide opening 212 to place the guide wheel 330 in the guide channel 211. The guide wheel 330 can roll with the guide side wall to realize the movement of the mounting seat 300. In addition, the first roller 341 and the second roller 342 can roll with the guide side wall. In this way, the guide side wall can be clamped between the guide wheel 330 and the first roller 341 and the second roller 342, further improving the movement stability of the mounting seat 300.

[0090] Please see Figure 9 In one embodiment, at least two guide seats 320 are provided and spaced apart along a first direction, and at least two guide wheels 330 are provided and are provided in a one-to-one correspondence with the guide seats 320.

[0091] Please see Figure 6 and Figure 8 In one embodiment, the inner wall of the mounting channel 310 is further provided with a first auxiliary wheel 351, a second auxiliary wheel 352 and a third auxiliary wheel 353. The first auxiliary wheel 351, the second auxiliary wheel 352 and the third auxiliary wheel 353 respectively roll in cooperation with the three side walls of the guide post 210 other than the guide side wall, thereby further improving the movement stability of the mounting base 300.

[0092] Furthermore, the first auxiliary wheel 351 is provided with at least two and is spaced apart along the first direction, the second auxiliary wheel 352 is provided with at least two and is spaced apart along the first direction, and the third auxiliary wheel 353 is provided with at least two and is spaced apart along the first direction.

[0093] Please see Figure 1 , Figure 8 and Figure 9In one embodiment, the cable trench cover construction device further includes a handle mechanism 800, which includes a mounting plate 810, a handle 820, and a locking rod 830.

The guide post 210 is provided with a locking engagement part 213, which extends along the axial direction of the guide post 210. The mounting base 300 is provided with a mounting through hole, which communicates with the mounting channel 310. The locking rod 830 passes through the mounting through hole and can reciprocate along the axial direction of the mounting through hole. The locking part 831 can engage with the locking engagement part 213.

[0094] With this configuration, workers can not only move the mounting base 300 along the first direction by holding the handle 820, but also move the locking rod 830 back and forth along the axis of the mounting through hole by pulling the handle 820. This allows the end of the locking rod 830 away from the mounting plate 810 to engage with the locking mating part 213, thereby positioning the mounting base 300 and preventing the mounting base 300 from moving on the guide column 210 when the cable trench cover construction device is lifting or lowering the cover 900, thus improving the ease of use of the cable trench cover construction device.

[0095] Please see Figure 1 and Figure 9 In one embodiment, the snap-fit ​​part 831 includes a snap-fit ​​protrusion, and the snap-fit ​​mating part 213 includes a plurality of snap-fit ​​grooves spaced apart along the axial direction of the guide post 210.
