Description

Technical Field

[0001] The utility model relates to the technical field of cable cutting, in particular to a cable cutting device for cable laying. Background Art

[0002] With the rapid development of urban construction, municipal renovation projects are increasing. Among them, the renovation of power cables is more common. During the laying process, the cables need to be cut. However, operators generally rely on electric saws and manual work to cut the cables. It is difficult to control the cable swing when the electric saw is cutting the cable. It also requires multiple people to press the cable to prevent the cable from swinging during cutting. The cable also needs to be lifted to prevent the electric saw from cutting the stones or other metal objects on the ground and damaging the electric saw. The cutting process is not stable and has low safety, which affects the normal use of the cable.

[0003] Manual cable cutting requires the cooperation of multiple people, which is not only labor-intensive and inefficient, but also wastes manpower. In addition, the smoothness of the cutting cannot be maintained. When cutting thicker cables, the cables will shake, which may injure the operators. In addition, the cable breaks and chamfers cannot be smooth and flat, which may easily lead to the inability to tightly overlap the cables and cable connectors, leaving safety hazards. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a cable cutting device for cable laying. The cost reduction device is placed above the laid cable, the sliding extrusion device is started to lift the cable, and the lifted cable part is cut by the cutting device. There is no need to lift the cable manually, which reduces the labor intensity of the operator, saves labor costs, and ensures the safety of the cutting work.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A cable cutting device for cable laying comprises a base plate, three mutually parallel through grooves are provided at both ends and the middle of the base plate, sliding extrusion devices are provided on the through grooves at both ends of the base plate, a cutting device is installed at one end of the through groove in the middle of the base plate through a hinge shaft, the sliding extrusion device comprises support plates installed at both ends of the through groove, a bidirectional threaded rod is provided between the support plates, thread blocks are provided at both ends of the bidirectional threaded rod, wedge blocks are provided at the bottom of the two threaded blocks, and the sharp parts of the wedge blocks are arranged opposite to each other.

[0007] Preferably, the wedge blocks at the bottom of the two threaded blocks are right triangles, one acute angle of the two wedge blocks is connected to the corresponding bottom of the threaded block, the other acute angles of the two wedge blocks are relatively arranged, and the two corresponding wedge blocks are staggered.

[0008] Preferably, the bottom of the threaded block is arranged through the through slot, the width of the threaded block is adapted to the width of the through slot, and a driving motor for driving the bidirectional threaded rod to rotate is installed on the support plate at one end of the through slot.

[0009] Preferably, the cutting device includes a support rod, one end of the support rod is connected to one end of the through groove on the bottom plate through a hinge shaft, a cutting blade is arranged in the middle of the support rod, a cutting motor for driving the cutting blade to rotate is arranged in the middle of the support rod, and a handle is arranged at the free end of the support rod.

[0010] Preferably, columns are provided at the four corners of the bottom of the base plate, the bottom ends of the columns are in the same horizontal plane as one of the right-angled sides of the wedge-shaped block, and the radius of the cutting blade is smaller than the height of the columns.

[0011] Preferably, rollers are installed on both sides of one end of the base plate through supporting feet, the supporting feet are arranged obliquely, the bottom end of the outer edge of the roller is in the same horizontal plane as the bottom end of the column, and a handle is installed on the side of the other end of the base plate.

[0012] Preferably, a limiting member is provided at the through groove in the middle of the bottom plate, and the limiting member is provided at an end of the through groove away from the hinge shaft.

[0013] Preferably, the bottom of the threaded block is rotatably connected to a wedge block via a connecting shaft, and the wedge block is a right-angled triangle.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The utility model has a simple structure. The two-way threaded rod rotates to drive the threaded blocks at both ends of the two-way threaded rod to move relative to each other, and the wedge block at the bottom of the threaded block follows the relative movement. Since the bottom end of the column and one of the right-angled sides of the wedge block are in the same horizontal plane, when the column contacts the ground, the wedge block can contact the ground. During the relative movement of the wedge block, the wedge block can extend into the bottom of the cable, follow the relative movement of the wedge block, and lift the cable away from the ground until the wedge block lifts the cable to abut against the bottom of the base plate, and the cable is completely away from the ground. Since sliding extrusion devices are provided at both ends of the base plate, the cable in the middle of the base plate is away from the ground and abuts against the bottom of the base plate, thereby avoiding multiple people manually moving the cable, reducing labor costs and reducing the labor intensity of operators.

[0016] 2. The radius of the cutting blade of the device is smaller than the height of the column, which can prevent the cutting blade from contacting the ground and causing damage to the cutting blade, thereby increasing the service life of the device.

[0017] 3. The handle of the device makes it easy for the operator to lift the end of the device with the handle. When the end of the device with the handle is lifted, all the columns at the bottom of the base plate are away from the ground, and the rollers are in contact with the ground, which makes it easy for the operator to move the device and improves the maneuverability of the device. Only one person is needed to move the device, which reduces the labor intensity of the operator and improves the practicality of the device.

[0018] 4. When the device is moved, the support rod may shake or even move away from the corresponding through slot. The end of the support rod away from the hinge shaft is limited by a limiting member so that the support rod is always in contact with the bottom plate, thereby improving the stability of the device when moving.

[0019] 5. The wedge block of the device is connected to the bottom of the threaded block through a connecting shaft to ensure that the wedge block can rotate. When cutting a thicker cable, the wedge block is rotated in advance to make the two corresponding wedge blocks parallel, which is convenient for placing the device above the cable. After the device is placed, the wedge block is rotated to reset, which is convenient for sliding, squeezing and cutting of the cable, thereby improving the practicality of the device.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Embodiment 1

[0026] A cable cutting device for cable laying, the structure is as follows Figure 1-Figure 3As shown, it comprises a bottom plate 1, three mutually parallel through grooves are opened at both ends and the middle of the bottom plate 1, and sliding extrusion devices are arranged on the through grooves at both ends of the bottom plate 1, and a cutting device is installed at one end of the through groove in the middle of the bottom plate 1 through a hinge shaft 7, and the sliding extrusion device comprises a support plate 2 installed at both ends of the through groove, a bidirectional threaded rod 3 is arranged between the support plates 2, and thread blocks 4 are arranged at both ends of the bidirectional threaded rod 3, and wedge blocks 5 are arranged at the bottom of the two thread blocks 4, and the sharp parts of the wedge blocks 5 are arranged oppositely. The four corners of the bottom of the bottom of the bottom plate 1 are provided with columns 14, and the bottom end of the column 14 is in the same horizontal plane with one of the right-angled sides of the wedge block 5, and the radius of the cutting blade 9 is smaller than the height of the column 14. The wedge blocks 5 at the bottom of the two thread blocks 4 are both right triangles, and one acute angle of the two wedge blocks 5 is connected to the bottom of the corresponding thread block 4, and the other acute angles of the two wedge blocks 5 are arranged oppositely, and the two corresponding wedge blocks 5 are arranged in a staggered manner.

[0027] By placing the device above the laid cable and determining the position to be cut, the bidirectional threaded rod 3 is rotated to drive the threaded blocks 4 at both ends of the bidirectional threaded rod 3 to move relative to each other, and the wedge block 5 at the bottom of the threaded block 4 follows the relative movement. Since the bottom end of the column 14 and one of the right-angled sides of the wedge block 5 are in the same horizontal plane, when the column 14 contacts the ground, the wedge block 5 can contact the ground. During the relative movement of the wedge block 5, the wedge block 5 can extend into the bottom of the cable and follow the relative movement of the wedge block 5 to lift the cable away from the ground until the wedge block 5 lifts the cable to abut against the bottom of the bottom plate 1, and the cable is completely away from the ground. Since sliding extrusion devices are provided at both ends of the bottom plate 1, the cable in the middle of the bottom plate 1 is away from the ground and abuts against the bottom of the bottom plate 1.

[0028] By the operator rotating the cutting device through the shaft, the cable can be cut off from the through groove in the middle of the bottom plate 1. Since the cable itself has gravity, the wedge block 5 can squeeze the cable to achieve stable contact with the ground. Because the radius of the cutting blade 9 is smaller than the height of the column 14, it can avoid contact between the cutting blade 9 and the ground, causing damage to the cutting blade 9, thereby improving the service life of the device. In addition, the device only requires one operator to complete the cable cutting work, without the need to lift the cable manually, reducing the labor intensity of the operator, while saving labor costs and ensuring the safety of the cutting work.

[0029] The bottom of the threaded block 4 is arranged through the through slot, the width of the threaded block 4 is adapted to the width of the through slot, and a driving motor 6 for driving the bidirectional threaded rod 3 to rotate is installed on the support plate 2 at one end of the through slot.

[0030] The bidirectional threaded rod 3 is driven to rotate by the driving motor 6 to realize the bidirectional movement of the threaded block 4, thereby preventing the threaded block 4 from idling and causing the wedge block 5 to be unable to move relatively. Therefore, the threaded block 4 passes through the corresponding through-groove setting to limit the threaded block 4, ensuring that when the bidirectional threaded rod 3 rotates, the threaded block 4 drives the wedge block 5 to follow the movement, thereby realizing the sliding extrusion of the cable, so that the cable abuts against the bottom of the base plate 1.

[0031] The cutting device includes a support rod 8, one end of which is connected to one end of a through groove on the base plate 1 through a hinge shaft 7, a cutting blade 9 is arranged in the middle of the support rod 8, a cutting motor 10 for driving the cutting blade 9 to rotate is arranged in the middle of the support rod 8, and a handle 11 is arranged at the free end of the support rod 8.

[0032] Since one end of the support rod 8 is connected to the base plate 1 through the hinge shaft 7, when cutting the cable, the end of the support rod 8 away from the hinge shaft 7 is lifted up through the handle 11, and the cutting blade 9 in the middle of the support rod 8 is lifted up away from the base plate 1, and the cutting motor 10 is started to drive the cutting blade 9 to rotate. The operator drives the end of the support rod 8 away from the hinge shaft 7 to move downward through the handle 11, so that the cutting blade 9 passes through the corresponding through groove to cut the cable. Only one person is needed to complete the cable cutting work, which reduces the labor cost and the labor intensity of the operator and improves the practicality of the device.

[0033] Rollers 13 are installed on both sides of one end of the base plate 1 through supporting feet 17. The supporting feet 17 are arranged tilted. The bottom end of the outer edge of the roller 13 is in the same horizontal plane as the bottom end of the column 14. A handle 15 is installed on the side of the other end of the base plate 1.

[0034] The handle 15 makes it easy for an operator to lift one end of the device having the handle 15. When the one end of the device having the handle 15 is lifted, all the columns 14 at the bottom of the base plate 1 are away from the ground, and the rollers 13 are in contact with the ground, so that the operator can move the device easily, thereby improving the mobility of the device. Only one person is needed to move the device, thereby reducing the labor intensity of the operator and improving the practicality of the device.

[0035] A limiting member 12 is disposed at the through groove in the middle of the bottom plate 1 , and the limiting member 12 is disposed at an end of the through groove away from the hinge shaft 7 .

[0036] To prevent the support rod 8 from shaking or even moving away from the corresponding through slot when the device is moved, the support rod 8 is limited by the end away from the hinge shaft 7 through the limiting member 12, so that the support rod 8 is always in contact with the bottom plate 1, thereby improving the stability of the device when moving.

[0037] Embodiment 2

[0038] On the basis of the first embodiment, the bottom of the threaded block 4 is rotatably connected to a wedge block 5 via a connecting shaft 16, and the wedge block 5 is a right-angled triangle.

[0039] In order to avoid the situation where the cable cannot pass through the wedge block 5 due to the thick cable and the narrow distance between the wedge blocks 5, the wedge block 5 is connected to the bottom of the threaded block 4 through the connecting shaft 16 to ensure that the wedge block 5 can rotate. When cutting the thicker cable, the wedge block 5 is rotated in advance to make the two corresponding wedge blocks 5 parallel, so that the device can be placed above the cable. After the device is placed, the wedge block 5 is rotated to reset, which is convenient for the subsequent sliding, squeezing and cutting of the cable, thereby improving the practicality of the device.

[0040] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or additions, subtractions or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
