Description

Technical Field

[0001] The invention relates to the technical field of trenching machines, in particular to a trenching device for solar photovoltaic power generation construction. Background Art

[0002] Photovoltaic panels used for photovoltaic power generation are often installed in open areas such as plains, mountains, and deserts where solar energy is not blocked and can be captured to the greatest extent. In the construction of photovoltaic panels, trenches for pre-buried cables need to be dug in advance and the cables need to be buried underground, so trenchers are needed. Trenchers include disc trenchers and chain trenchers.

[0003] The chain trencher has the characteristics of small body size and deep trenching, and is widely used in practice. It includes a tool chain that can rotate along an axis. The axis is set at one end of the tool chain. By rotating the tool chain along the axis, the end away from the axis is controlled to drop a certain depth to achieve the purpose of controlling the trench depth. The chain trencher is often used to dig trenches along a linear path, and is particularly suitable for photovoltaic panels installed along a linear path.

[0004] In actual application, chain trenchers have high requirements for site flatness (construction sites are often leveled in advance). During construction by traction, it is necessary to pay attention to keeping the inclination of the machine body consistent with the trench width to avoid excessive inclination of the machine body in the forward direction, which causes the tool chain to tilt in the same direction in the trench. However, in construction on sites such as mountainous areas where it is difficult to level the site, it is inconvenient for chain trenchers to overcome uneven construction sites for linear trenching, so chain trenchers are extremely restricted by the construction site. In addition, the machine body and the tool chain are movably connected through an axis. When the tool chain tilts to the side and squeezes against the trench wall, the weight of the machine body tilts to one side, and the lateral component of gravity will act on the above-mentioned axis and the side of the tool chain, which is easy to cause damage to the tool chain and the components connected to the above-mentioned axis. When a conventional tractor tows the machine body to move, even in a leveled construction site, there is still left and right swinging, which causes the tool chain to tilt to the side and squeeze against the trench wall. Over time, it will cause damage to the tool chain and the components connected to the axis on one side. Summary of the invention

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the accompanying drawings.

[0030] Combination Figure 1-Figure 9 A trenching device for solar photovoltaic power generation construction includes a trenching body 10, the trenching body 10 has a tool chain 11 that rotates downward and is used for trenching, and a traction mechanism 20 that can flexibly pull it is provided on one side of the trenching body 10. The traction mechanism 20 and the trenching body 10 are flexibly connected through a universal traction rod 21, so that the traction mechanism 20 can pull the trenching body 10. When the traction mechanism 20 swings left and right, it will not force the trenching body 10 to swing left and right. The trenching body 10 is provided with a front wheel 12 on one side close to the traction mechanism 20, and a supporting mechanism 30 that is inserted into the trench and used to stabilize the trenching body 10 is provided on the other side. The front wheel 12, the tool chain 11, and the supporting mechanism 30 are in the same vertical plane, and the front wheel 12 cooperates with the supporting mechanism 30 to vertically support the trenching body 10;

[0031] The supporting mechanism 30 includes a supporting assembly 31 mounted on one side of the trenching machine body 10, and a separating assembly 32 suspended above the trench is mounted on one side of the supporting assembly 31. A plurality of wall-hanging assemblies 33 extending into the trench are arranged below the separating assembly 32. The plurality of wall-hanging assemblies 33 are evenly distributed and pressed on both sides of the trench side walls through the separating assembly 32. The wall-hanging assemblies 33 include a roller 333 rolling on the trench side walls, and the arc surface of the roller 333 is provided with blades 334 rollingly embedded in the trench side walls, and also includes a lower slide plate 335 sliding on the bottom of the trench. When the traction mechanism 20 pulls the trenching machine body 10 to drive the wall-hanging assemblies 33 to move on the inner side of the trench, the wall-hanging assemblies 33 have the characteristics of anti-pulling, anti-compression and anti-tilting to support the separating assembly 32, and inversely constrain the trenching machine body 10 to be in a vertical state through the supporting assembly 31.

[0032] When the trenching machine body 10 is supported vertically by the front wheel 12 and the supporting mechanism 30, and before the tool chain 11 is started, the supporting assembly 31 and the separating assembly 32 are first controlled so that the multiple lower slide plates 335 are supported to the bottom of the trench, and then the separating assembly 32 is controlled to press the multiple rollers 333 against the side walls of the trench respectively, and the inserting blades 334 are inserted into the mud of the side walls of the trench. When the separating assembly 32 is firmly fixed on the trench by the multiple wall-hanging assemblies 33, the inserting blades 334 make the rollers 333 have the ability to resist both pulling out and compression on the side walls of the trench, and the inserting blades 334 on the surfaces of the rollers 333 on both sides are respectively inserted into the two side walls of the trench, so that the separating assembly 32 supported by the wall-hanging assembly 33 also has the ability to resist tilting. In summary, the separating assembly 32 is provided with a stable supporting capability, and because the rollers 333 are arranged to roll, the rolling forward of the rollers 333 on the side walls of the trench will not be affected;

[0033] Because the trench is vertical, the separation assembly 32 supported by the wall hanging assembly 33 squeezed on the inner walls of both sides of the trench is also vertical, so the trenching machine body 10 is reversely supported by the support assembly 31, so that the trenching machine body 10 also maintains a vertical state. When the trenching machine body 10 is moved by the traction mechanism 20 and the tool chain 11 is started to perform vertical trenching, the trenching machine body 10 is constrained to be in a vertical state by the supporting mechanism 30, so that the trenching machine body 10 maintains a vertical state and moves in a straight line direction. Among them, the traction mechanism 20 It only provides pulling force for the trenching body 10. When the traction mechanism 20 swings, it only changes the direction of pulling the trenching body 10, and will not force the trenching body 10 to tilt. The lateral force generated by changing the direction of pulling the trenching body 10 due to the swing will be overcome by the supporting effect of the support assembly 31. Therefore, the trenching body 10 is constrained to be vertical based on the vertical channel through the supporting mechanism 30. Even in an uneven construction site, it can perform vertical linear trenching, which greatly improves the practical scenarios of the trenching body 10.

[0034] Combination Figure 1 A side auxiliary wheel 13 is provided on one side of the trenching machine body 10. The frame for assembling the side auxiliary wheel 13 can control the lifting of the side auxiliary wheel 13. Before the trench is dug at the site, the separation assembly 32 is in a propped-up state by the support assembly 31. At this time, the trenching machine body 10 is supported by the front wheel 12 and the side auxiliary wheel 13 on one side. The side auxiliary wheel 13 can be provided in plurality, so as to support the trenching machine body 10 to maintain a vertical state.

[0035] Before starting the trenching machine 10 for the first time, the trenching machine 10 is first towed to a small area of ​​sufficiently flat ground, then the tool chain 11 is started, and one end of the started tool chain 11 is lowered to the depth of the trench to be opened, and then the traction mechanism 20 is started to tow the trenching machine 10 to move linearly for a short distance, so that the wall hanging component 33 can be placed in the opened vertical trench. After the wall hanging component 33 is placed in the trench and forms a force connection with the trench wall, the supporting mechanism 30 can play the role of vertically supporting the trenching machine 10. At this time, the side auxiliary wheel 13 can be raised, and it is no longer necessary for it to provide auxiliary support for the trenching machine 10; for mountainous areas, a small area of ​​flat ground can be opened manually in advance, and the required leveling area is small, and the labor required can be ignored.

[0036] Combination Figure 3-Figure 4The separation component 32 includes an assembly frame 321 assembled at one end of the support component 31, a pair of separation platforms 322 are movably assembled on the inner side of the assembly frame 321 through a rotatably installed driving screw 323, a plurality of wall-mounted components 33 are fixedly assembled on the lower surface of the pair of separation platforms 322, and the plurality of wall-mounted components 33 are evenly distributed on two side slides 332, and the wall-mounted components 33 on the two side slides 332 are equidistantly distributed on both sides of the vertical center plane of the assembly frame 321;

[0037] At least two drive screws 323 are provided, and the surface has threads in opposite directions from the center to both sides. The drive screw 323 passes through the inner side of the separation platform 322. The separation platform 322 is provided with an internal thread that matches the drive screw 323. One end of the drive screw 323 is provided with a synchronous drive rod 324 that drives it to rotate. One end of the synchronous drive rod 324 shaft is connected to a reduction motor 325 that drives it to rotate. One end of the drive screw 323 is equipped with a turbine. The surface of the synchronous drive rod 324 is coaxially equipped with a worm that meshes with the turbine. The reduction motor 325 drives the synchronous drive rod 324 to rotate, thereby causing multiple drive screws 323 to rotate synchronously, thereby controlling the two separation platforms 322 to separate or merge synchronously.

[0038] Furthermore, by synchronously controlling the separation of the two separation tables 322, the wall-mounted components 33 connected on the lower side are forced to simultaneously abut against the side walls of the groove, so as to support the separation component 32 directly above the groove, so that the separation component 32 and the tool chain 11 are maintained in the same vertical plane, and the wall-mounted components 33 are forced to move forward in a straight line along the newly opened groove of the tool chain 11, while ensuring that the center plane of the separation component 32 along the forward direction remains vertical.

[0039] Combination Figure 4 The surfaces of the two separation platforms 322 that are in contact with each other have mutually embedded protrusions, and the wall-hanging components 33 are fixedly assembled on the lower side of the protrusions. When the two separation platforms 322 are merged, the vertical center planes of the multiple wall-hanging components 33 on the lower side and the assembly frame 321 are coplanar. Therefore, based on the groove width, the cross-sectional diameter of the roller 333, or the maximum distance of the outer end of the blade 334 can be designed to be larger, so as to form a more stable connection with the groove side wall.

[0040] Combination Figure 5 , Figure 6 , Figure 8 The roller 333 is assembled to the lower side of the separation table 322 through the support rod 331 connected by inner rotation, and the lower slide plate 335 is assembled on the lower end of the support rod 331. The lower end of the support rod 331 is movably and telescopically provided with a movable rod 3311. The lower end of the movable rod 3311 fixes the lower slide plate 335 through a connecting seat 3313. The surface of the movable rod 3311 is also provided with a push spring 3312 that elastically supports the connecting seat 3313.

[0041] Furthermore, the lower slide plates 335 correspondingly connected to the lower ends of the multiple support rods 331 slide against the bottom of the trench, thereby supporting the separation component 32, and further achieving the purpose of supporting the trenching machine body 10. When the trenching machine body 10 moves on an uneven site, the bottom surface of the trench to be dug will also be uneven along the forward direction. At this time, the lower slide plates 335 are elastically supported by the push spring 3312, so that the multiple lower slide plates 335 can fit into the trench bottom when sliding on the uneven trench bottom, so as to fully utilize the multiple lower slide plates 335 to support the trenching machine body 10.

[0042] In the previous embodiment: the blade inserting 334 includes blades circumferentially arranged on the surface of the drum 333, and the blades are parallel to the cross-section of the drum 333 (not shown in the figure, it can be understood as the shape of the existing straight-wing fan blades, and the fan blades are arranged parallel to the cylindrical cross-section). When the drum 333 rolls on the side wall of the groove, the circumferentially arranged blades can be continuously inserted into the mud wall, thereby providing the wall hanging component 33 with anti-pullout and anti-compression effects.

[0043] like Figure 5 As shown, the side surfaces of the plurality of support rods 331 on the same side may also be provided with side slide plates 332 that fit the mud wall, so as to further enhance the lateral anti-deflection capability of the wall-hanging assembly 33 .

[0044] Combination Figure 5-Figure 6 The blade 334 includes an arc-shaped spiral blade 334a fixed on the arc surface of the drum 333, and a cross-section portion 334b ​​is provided on one side of the arc-shaped spiral blade 334a. The cross-section portion 334b ​​is tangent to the surface of the drum 333, and a friction damping component 336 is provided between the drum 333 and the support rod 331 to damp the rotation thereof.

[0045] Furthermore, when the roller 333 rolls on the side wall of the groove, the setting of the arc-shaped spiral blade 334a can enhance the pull-out resistance of the support rod 331 and the downward pressure on the lower slide plate 335, thereby further enhancing the stability of the support mechanism 30 in the groove. The principle is as follows: since the surface of the arc-shaped spiral blade 334a is a continuous inclined surface, and the rotation connection between the roller 333 and the support rod 331 has damping, the arc-shaped spiral blade 334a is inserted into the mud wall and rolls, and it is necessary to overcome the rotation resistance between the roller 333 and the support rod 331. This resistance allows the arc-shaped spiral blade 334a to simultaneously perform sliding friction and rolling friction in the mud wall of the groove, wherein the sliding friction will squeeze the upper surface of the arc-shaped spiral blade 334a, prompting the roller 333 to rotate. The support rod 331 squeezes the lower slide plate 335, so that the lower slide plate 335 is simultaneously subjected to the weight of the trenching machine body 10 and the downward pressure exerted by the arc-shaped spiral blade 334a, forming a greater pressure against the bottom surface of the trench, and the layer on the bottom surface of the trench is pressed more tightly by the lower slide plate 335, thereby providing a greater resistance to pressure for the lower slide plate 335; further, the arc-shaped spiral blade 334a with an inclined surface is inserted into the side wall of the trench and moves with the separation component 32. Due to the resistance of the rotation between the roller 333 and the support rod 331, the arc-shaped spiral blade 334a first slides on the side wall, and the arc-shaped spiral blade 334a is inserted into the mud wall, which is equivalent to obliquely cutting the mud wall. It will be squeezed downward by the soil in the vertical direction. The arc-shaped spiral leaf 334a is pressed down further by the support rod 331, and the soil on the upper surface of the arc-shaped spiral leaf 334a is compressed by the reverse pressure to form a more compact soil. The resistance of the compacted soil to the arc-shaped spiral leaf 334a is also increased. When the increased resistance is sufficient to overcome the rotation resistance between the roller 333 and the support rod 331, the roller 333 can rotate on the surface of the support rod 331. The resistance of the compacted soil to the arc-shaped spiral leaf 334a also increases the pull-out resistance of the wall-mounted component 33. The setting of the arc-shaped spiral leaf 334a makes the supporting mechanism 30 has greater compression and pull-out resistance in the trench, thereby better providing a stable support effect for the trenching machine body 10, preventing the trenching machine body 10 from tilting; wherein, the purpose of the setting of the cross-section portion 334b ​​is to prevent the support rod 331 from being continuously moved downward by the arc-shaped spiral leaf 334a, resulting in excessive increase in the pressure on the lower slide plate 335, which will be converted into elastic potential energy of the push spring 3312; when the cross-section portion 334b ​​turns to contact the trench wall, the arc-shaped spiral leaf 334a is in a state of being separated from the mud wall and under pressure, and the push spring 3312 can release the elastic potential energy to a certain extent, thereby preventing the arc-shaped spiral leaf 334a from continuously increasing the pressure on the lower slide plate 335 through the support rod 331;

[0046] Among them Figure 7As shown, the friction damping assembly 336 includes a second arc-shaped friction plate 3362 fixed on the surface of the support rod 331, and a first arc-shaped friction plate 3361 fixed on the inner surface of the roller 333. The first arc-shaped friction plate 3361 and the second arc-shaped friction plate 3362 are in friction contact to provide a damping force for the rotational connection between the roller 333 and the support rod 331. The positions of the first arc-shaped friction plate 3361, the second arc-shaped friction plate 3362 and the cross-sectional portion 334b ​​are designed correspondingly, so that when the cross-sectional portion 334b ​​rotates to contact the mud wall, the first arc-shaped friction plate 3361 and the second arc-shaped friction plate 3362 are disconnected from the frictional contact, so that the rotational connection between the support rod 331 and the roller 333 has no damping effect. In this way, the friction force of the mud wall on the surface of the roller 333 can drive the roller 333 to rotate, so that one end of the arc-shaped spiral leaf 334a is reinserted into the mud wall.

[0047] It should be noted that the above-mentioned mud wall represents the side wall of the trench, which is to indicate that the blade 334 can be inserted into the interior; in the forward direction of the trenching machine body 10, the cross-sectional portions 334b ​​on one side of the arc-shaped spiral blades 334a in the same row are not at the same angle, so as to avoid that multiple cross-sectional portions 334b ​​rotate to one side of the mud wall at the same time, causing multiple push springs 3312 on one side to release elastic force at the same time, causing the separation component 32 to tilt.

[0048] Combination Figure 8-Figure 9 The lower slide plate 335 has a second tilt 3352 on one side along its sliding direction, and the second tilt 3352 has a first tilt 3351 on the side away from the groove side wall, and the height of the first tilt 3351 is greater than the second tilt 3352.

[0049] Specifically, when the lower slide plate 335 slides on the groove bottom, the design of the second tilt 3352 makes it easier for the lower slide plate 335 to slide on the soft groove bottom, and the design of the first tilt 3351 makes the lower slide plate 335 deviate towards the direction of the groove side wall during sliding. In this way, the lower slide plate 335 can also provide a thrust for the roller 333 to press against the groove side wall through the support rod 331, so that the roller 333 and the blade 334 form a more stable connection with the groove side wall.

[0050] Combination Figure 1-Figure 2The support assembly 31 includes a first cantilever 312 and a second cantilever 313 that are rotatably connected. The first cantilever 312 is rotatably mounted on one side of the trenching machine body 10 through a first fixed seat 311. A first hydraulic rod 315 for controlling its rotation is provided at the lower side of the first cantilever 312, and a second hydraulic rod 316 for controlling its rotation is provided at the upper side of the second cantilever 313. The first cantilever 312 and the second cantilever 313 are rotatably adjusted up and down in a vertical plane. The second cantilever 313 is rotatable with the separation assembly 32 through a second fixed seat 314. The second cantilever 313 is connected to the separating component 32 and is rotated and adjusted in the lateral direction of the trenching body 10 during its movement. A third hydraulic rod 317 is provided on the upper side of the second fixed seat 314 for pushing the second cantilever 313 to rotate in the lateral direction. A tilt sensor 14 for detecting the tilt angle of the trenching body 10 is installed on the trenching body 10. The tilt sensor 14 detects the tilt angle of the trenching body 10 in the lateral direction during its movement. The tilt sensor 14 and the third hydraulic rod 317 are coordinated and controlled through a linkage controller.

[0051] The position of the outer end of the second cantilever 313 is controlled by the first hydraulic rod 315 and the second hydraulic rod 316, so that the separation component 32 can be placed in the trench in a suitable state when the trenching machine body 10 is in a vertical state. During this process, the third hydraulic rod 317 is in a locked state, and the separation component 32 is controlled to be horizontal in the lateral direction; when the trenching machine body 10 is towed and moved by the traction mechanism 20, when the traction mechanism 20 swings too much, the excessive lateral pulling force may pull the trenching machine body 10 to one side, causing the trenching machine body 10 to be tilted to one side together with the separation component 32 and the wall hanging component 33. At this time, the tilt angle of the trenching machine body 10 in the movement is detected in real time by the inclination sensor 14, and then the third hydraulic rod 317 is appropriately extended and retracted by the linkage controller to correct the tilted trenching machine body 10. In the correction, the first step is: tilt The inclined trenching machine body 10 causes the wall hanging component 33 to be tilted and stuck in the trench and move forward. Although the wall hanging component 33 is tilted, it is still clamped by force with the mud wall. At the same time, the trench opened by the trenching machine body 10 will also be tilted, which is easy to affect the linear trenching process of the trenching machine body 10. In this embodiment, the third hydraulic rod 317 is used to adjust the relative angle between the separation component 32 and the trenching machine body 10 on the vertical plane, so that the trenching machine body 10 is calibrated to verticality on the inclined separation component 32. At this time, the trench opened by the trenching machine body 10 will be restored to verticality. When the wall hanging component 33 enters the corrected vertical trench again, the length of the third hydraulic rod 317 is controlled to be restored, so that the trenching machine body 10 and the separation component 32 are restored to maintain a vertical state, so that the trenching machine body 10 continues to perform linear trenching vertically. Through the above-mentioned settings, the trenching machine body 10 can adapt to more complex terrains.

[0052] It should be noted that the "vertical plane" described above is a vertical plane parallel to the forward direction of the trenching machine body 10. When the front wheel 12 is traveling on complex terrain and causes up and down shaking, it does not affect the linear trenching of the trenching machine body 10. In addition, the outer digging teeth of the existing tool chain 11 used for trenching will exceed the side of the tool chain 11 in the lateral direction, such as the outer digging teeth in the "trenching assembly of a chain trenching machine" disclosed in patent number "CN113863408A". The width of the trench dug by the outer digging teeth will be slightly larger than the width of the tool chain 11. Therefore, the trenching machine body 10 is allowed to tilt slightly to the side within an appropriate range, which will not cause the side of the tool chain 11 to be squeezed onto the mud wall, but the trench opened by the tilted trenching machine body 10 will also be tilted. Based on this, through the above embodiment, the trenching machine body 10 can be corrected in real time to ensure that the trenching machine body 10 can groove linearly and vertically.

[0053] Working principle: Before starting the trenching machine 10 for the first time, the trenching machine 10 is first towed to a small and sufficiently flat site, and the trenching machine 10 is supported by the side auxiliary wheels 13 to keep it in a vertical state, and then the tool chain 11 is started, and the traction mechanism 20 is started to pull the trenching machine 10 to open a trench into which the wall hanging assembly 33 can be placed, and then the support assembly 31 is controlled to descend to separate the height of the assembly 32, and the wall hanging assembly 33 is placed in the trench, and the wall hanging assembly 33 is force-connected with the two side walls and the bottom surface of the trench, and the trenching machine is The body 10 is supported vertically, and then during the movement of the trenching body 10, the wall hanging assembly 33 will follow the movement and maintain a force connection with the trench, further maintaining the supporting effect on the trenching body 10, so that the trenching body 10 is not restricted by the site and maintains linear trenching. During trenching, when the traction mechanism 20 swings too much and the excessive lateral pulling force causes the trenching body 10 to be pulled off track, the inclined trenching body 10 can also be calibrated to vertical through the third hydraulic rod 317, so that the trenching body 10 can continue to perform linear trenching vertically.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
