Description

Technical Field

[0001] The invention relates to the field of cable laying, and in particular to a cable laying and installation machine. Background Art

[0002] When installing power facilities, it is necessary to bury the embedded pipe first, and then lay the cable. During the cable laying process, the cable needs to be passed through the embedded pipe. Generally, a traction machine is used to pull the cable through the embedded pipe, or a mobile trolley is used to move the cable inside the embedded pipe. However, due to the flying sand and gravel at the construction site and the open structure of the embedded pipe, sand and gravel are easy to enter the embedded pipe, which is easy to cause wear when the cable enters.

[0003] For example, Chinese patent CN116154681A discloses an underground cable laying device, which shovels away the sand and gravel in the pre-buried pipe and collects them by suction through the design of a sand suction nozzle, thereby solving the problem of sand and gravel in the pre-buried pipe. However, it does not distinguish between sand and gravel, resulting in gravel larger than sand being easily blocked in the suction hole, affecting subsequent suction operations. In addition, it adopts a large-area suction structure covering the pipe wall. When the pre-buried pipe is long, the suction energy consumption is large, which is not conducive to saving laying costs. Summary of the invention

[0004] In order to overcome the shortcoming of the existing cable laying device that the sand and gravel of different volumes in the embedded pipe are not distinguished and processed, the present invention provides a cable laying and installation machine.

[0005] The technical solution is: a cable laying and installation machine, comprising a fixed cylinder, an electric wheel group, a mounting column, a sand shoveling bucket and a suction unit, wherein the fixed cylinder is installed with a plurality of electric wheel groups in a circular array, one end of the fixed cylinder is open, and the open end of the fixed cylinder is used for the cable to be laid to pass through, and a clamping unit for clamping the cable to be laid is arranged in the fixed cylinder, and a mounting column is installed at the other end of the fixed cylinder, and a hollow sand shoveling bucket is installed on the mounting column, and a suction port is opened on the sand shoveling bucket, and a suction unit is installed on the fixed cylinder, and the suction unit sucks and collects sand and gravel in the pre-buried pipe through the suction port on the sand shoveling bucket;

[0006] Also includes:

[0007] A motor, wherein a mounting groove is formed at one end of the mounting column away from the sand shoveling bucket, and the motor is mounted in the mounting groove;

[0008] A rotating wheel, the rotating wheel is mounted on the rotating shaft of the motor;

[0009] Brushes, wherein a plurality of brushes are provided and installed on the rotating wheel in a ring array, and the inner wall of the embedded pipe is pre-cleaned by the brushes.

[0010] Furthermore, the sand scooping bucket is located below the mounting column and is configured as a half trumpet cover structure.

[0011] Furthermore, five suction ports are arranged on the sand shoveling bucket, and the five suction ports are distributed along the curved surface of the sand shoveling bucket, and the five suction ports are distributed in a state where the lengths gradually decrease from the middle to both sides.

[0012] Furthermore, an interception plate is provided below the mounting column, the interception plate is located between the sand shoveling bucket and the rotating wheel, and a gap is left between the interception plate and the inner bottom wall of the embedded pipe for sand to pass through.

[0013] Furthermore, the cross section of the intercepting plate is V-shaped and the tip is facing the side close to the rotating wheel.

[0014] Furthermore, the brush is in an inclined state, and the sand and gravel swept down by the brush in the inclined state are caused to fall to a side close to the interception plate.

[0015] Furthermore, a groove is provided at the bottom of the mounting column, and a telescopic driving member is installed in the groove, a connecting plate is installed at the driving end of the telescopic driving member, a shielding plate is installed at one end of the connecting plate, and the shielding plate covers half of the three suction ports in the middle, and the intercepting plate is installed at the other end of the connecting plate.

[0016] Furthermore, the suction unit includes a collection box and a suction pump, the collection box and the suction pump are both installed at the bottom of the fixed cylinder, and the sand shovel bucket, the collection box and the suction pump are connected in sequence through a pipeline.

[0017] Furthermore, a screen is provided in the collection box, and the screen divides the interior of the collection box into two spaces, an upper space and an lower space. The upper space is used to store large stones, and the lower space is used to store small sand.

[0018] Furthermore, the inner bottom of the collecting box is arranged in an inclined shape, the screen is arranged in an inclined shape, and the inner bottom of the collecting box and the screen are both arranged at a higher height on the side close to the sand shoveling bucket.

[0019] The beneficial effect is as follows: the present invention can not only make the tightly attached sand and gravel fall off through the pre-cleaning operation of the brush, which is convenient for the subsequent sand shoveling and suction, but also make the sand and gravel distributed on the inner bottom of the embedded pipe after falling off, so as to reduce the distribution area of ​​the sand and gravel and make the sand and gravel more concentrated. Based on this, the sand shoveling range can be reduced, so the sand shoveling bucket is set as half of the trumpet cover structure, and there is no need to cover the entire inner wall of the embedded pipe, which not only reduces the friction with the embedded pipe when shoveling sand, but also reduces the suction range and saves suction energy consumption.

[0020] The present invention performs separate suction and collection on the basis of distinguishing and processing sand and gravel, and can effectively distribute the use of suction power. There is no need to turn on a large suction power for a long time. The suction power is increased only when the gravel is being sucked. In addition, when large-volume gravel and small-volume sand are mixed and stacked, the large-volume gravel is easily stacked in a disorderly manner to form more gaps, and the utilization rate of the storage space is reduced. The design of the above-mentioned separate suction and collection can make the large-volume gravel and the small-volume sand be stacked in a relatively orderly manner, thereby solving the problem that the storage space in the suction unit is prone to filling gaps when sand and gravel are mixed and sucked.

DETAILED DESCRIPTION

[0028] The technical solution of the present invention is further described below in conjunction with the accompanying drawings.

[0029] Example 1

[0030] A cable laying and installation machine, such as Figure 1-Figure 5As shown, it includes a fixed cylinder 1, an electric wheel group 2, a mounting column 3, a sand shoveling bucket 4 and a suction unit. The outer ring surface of the fixed cylinder 1 is equipped with three electric wheel groups 2 in a circular array, and each electric wheel group 2 is composed of three electric walking wheels. One end of the fixed cylinder 1 is open, and a clamping unit is arranged in the fixed cylinder 1. The other end of the fixed cylinder 1 is equipped with a mounting column 3, and a sand shoveling bucket 4 with a hollow interior is installed on the mounting column 3. The sand shoveling bucket 4 fits the inner wall of the embedded pipe, and a suction port 401 is opened on the sand shoveling bucket 4. The fixed cylinder 1 is equipped with a suction unit;

[0031] Also includes:

[0032] Motor 7, the end of the mounting column 3 away from the sand shoveling bucket 4 is provided with a mounting groove, and the motor 7 is installed in the mounting groove;

[0033] A rotating wheel 8, wherein the rotating wheel 8 is mounted on the rotating shaft of the motor 7;

[0034] Brushes 9 , six of which are arranged in a circular array and installed on the rotating wheel 8 .

[0035] The clamping unit is composed of an electric push rod and a clamping plate (not shown in the figure). The electric push rod controls the movement of the clamping plate to clamp the cable. The clamping unit can also be replaced by other conventional clamping structures in the prior art.

[0036] The sand scooping bucket 4 is located below the mounting column 3 and is configured as a half trumpet cover structure.

[0037] There are five suction ports 401 on the sand scooping bucket 4 . The five suction ports 401 are distributed along the curved surface of the sand scooping bucket 4 , and the lengths of the five suction ports 401 decrease gradually from the middle to both sides.

[0038] An interception plate 10 is disposed below the mounting column 3 , and the interception plate 10 is located between the sand scooping bucket 4 and the rotating wheel 8 .

[0039] The interception plate 10 has a V-shaped cross section with its tip facing the side close to the rotating wheel 8 .

[0040] The brush 9 is in an inclined state, and the sand and stones swept down by the brush 9 in the inclined state are caused to fall to the side close to the interception plate 10 .

[0041] In this embodiment, when laying the cable, the end of the cable is placed in the clamping unit in the fixing tube 1, the cable is clamped by the clamping unit, and then the entire cable laying and installation machine is controlled to move into the pre-buried pipe by the operation of the electric wheel group 2, so as to pull and lay the cable;

[0042] During the movement, the motor 7 drives the wheel 8 and the brush 9 to rotate, and the sand and gravel in the embedded pipe are first cleaned by the brush 9, and then the sand and gravel are shoveled by the sand shoveling bucket 4, and the suction unit is operated to make the suction port 401 suck the sand and gravel into the internal cavity of the sand shoveling bucket 4, so that the sand and gravel are sucked into the suction unit for collection.

[0043] Among them, the pre-cleaning operation of the brush 9 can not only make the tightly attached sand and gravel fall off, which is convenient for the subsequent sand shoveling and suction, but also make the sand and gravel fall off and distribute on the inner bottom of the embedded pipe, so as to reduce the distribution area of ​​the sand and gravel and make the sand and gravel more concentrated. Based on this, the sand shoveling range can be reduced, so the sand shoveling bucket 4 is set to half of the trumpet cover structure, which does not need to cover the entire inner wall of the embedded pipe, which not only reduces the friction with the embedded pipe during sand shoveling, but also reduces the suction range and saves suction energy consumption.

[0044] Furthermore, since the bottom of the embedded pipe is an arc surface, the sand and gravel gathered at this position are distributed in a state where there is more in the middle and less on the two sides, so the five suction ports 401 are designed to be distributed in a state where the length gradually decreases from the middle to the two sides, so that the middle position with more sand and gravel can be adaptively sucked through the longer suction port 401 in the middle.

[0045] Furthermore, in order to prevent large-volume stones from blocking the suction port 401, an interception plate 10 is designed to solve the problem. A gap is left between the interception plate 10 and the inner bottom wall of the embedded pipe for small-volume sand to pass through, while large-volume stones are intercepted by the interception plate 10.

[0046] Since the inner bottom wall of the embedded pipe is an arc surface, more sand will accumulate at the lowest point. In order not to affect the normal passage of sand, the cross-section of the interception plate 10 is designed to be V-shaped. The V-shaped interception plate 10 guides the stones to move to both sides, leaving a gap for the sand to pass through at the lowest point.

[0047] It should be noted that a counterweight block is provided at the bottom of the fixing cylinder 1 so that the center of gravity of the entire cable laying and installation machine is located on the side close to the electric wheel set 2, thereby ensuring the stable movement and operation of the cable laying and installation machine.

[0048] Example 2

[0049] On the basis of Example 1, Figure 1-Figure 5 As shown, a groove is provided at the bottom of the mounting column 3, and a telescopic driving member 11 is installed in the groove. The telescopic driving member 11 is an electric push rod. A connecting plate 12 is installed at the driving end of the telescopic driving member 11. A shielding plate 13 is installed at one end of the connecting plate 12. The shielding plate 13 covers half of the three suction ports 401 in the middle. The intercepting plate 10 is installed at the other end of the connecting plate 12.

[0050] In this embodiment, due to the interception of stones by the interception plate 10, the stones will accumulate on the interception surface of the interception plate 10, which will hinder the movement of the electric wheel group 2 and cause greater wear on the embedded pipe. Therefore, the telescopic drive member 11 is controlled to rise periodically, and the connecting plate 12, the shielding plate 13 and the interception plate 10 are driven to move upward together by the telescopic drive member 11, so that the interception plate 10 moves up and no longer intercepts the stones, allowing the stones to reach the suction port 401 on the sand shovel 4, and the shielding plate 13 covering the suction port 401 is also moved up, so that the suction apertures of the three suction ports 401 in the middle are increased, and at the same time, the suction power of the suction unit is controlled to increase, so that the stones can also be sucked and collected;

[0051] Therefore, on the basis of distinguishing and treating sand and gravel, the two are separately sucked and collected, which can effectively allocate the use of suction power. There is no need to turn on a large suction power for a long time. The suction power is increased only when sucking gravel. In addition, when large-volume gravel and small-volume sand are mixed and stacked, the two are easily stacked in a chaotic manner to form more gaps, and the utilization rate of the storage space is reduced. The design of the above-mentioned separate suction and collection can make large-volume gravel and small-volume sand stacked more orderly, and solve the problem of mixed suction of sand and gravel, and the storage space in the suction unit is prone to filling gaps.

[0052] Example 3

[0053] On the basis of Example 2, Figure 1-Figure 6 As shown, the suction unit includes a collection box 5 and a suction pump 6, and the collection box 5 and the suction pump 6 are both installed at the bottom of the fixed cylinder 1, and the sand shovel 4, the collection box 5 and the suction pump 6 are connected in sequence through pipelines.

[0054] A screen 14 is provided in the collecting box 5 , and the screen 14 divides the interior of the collecting box 5 into two upper and lower spaces.

[0055] The inner bottom of the collecting box 5 is arranged in an inclined shape, the screen 14 is arranged in an inclined shape, and the inner bottom of the collecting box 5 and the screen 14 are both arranged at a higher height near the side of the sand shoveling bucket 4 .

[0056] In this embodiment, suction force is generated by the suction pump 6 to suck sand and gravel into the collection box 5 through the suction port 401 of the sand shovel 4 for collection, and the large-volume gravel is intercepted in the upper space by designing the screen 14, so that the large-volume gravel and the small-volume sand are stored separately, further solving the problem of chaotic stacking, reducing the generation of stacking gaps, and making efficient use of the storage space.

[0057] Furthermore, the inner bottom of the collecting box 5 and the screen 14 are designed to be inclined so that the sucked sand and gravel can first fill the side away from the entrance of the collecting box 5, thereby solving the problem of sand and gravel accumulating at the entrance of the collecting box 5, making it inconvenient for subsequent sand and gravel to enter.

[0058] The technical principles of the embodiments of the present invention are described above in conjunction with specific embodiments. These descriptions are only for explaining the principles of the embodiments of the present invention and cannot be interpreted in any way as limiting the protection scope of the embodiments of the present invention. Based on the explanations herein, those skilled in the art can think of other specific implementation methods of the embodiments of the present invention without creative work, and these methods will fall within the protection scope of the embodiments of the present invention.
