With the continuous development of the power industry, the specifications and lengths of cables are increasing, and the requirements for cable transportation tools are getting higher and higher. The existing cable transportation tools are also inconvenient during the handling and loading and unloading process. Among them, the cable drum generally includes a reel and circular side drums located on both sides of the reel.

The device will descend due to the influence of the gravity of the cable drum through the load-bearing plate, and the rotating gear will drive the loading plate to rotate and retract, so that the two loading plates will not interfere with each other during the movement of the whole device, providing a good way to make way, so that the automatic fixation of the cable during the transportation process can be well realized, without the need for manual bundling and installation, reducing labor intensity and improving its stability during movement.

[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0029] See also Figure 1-10A cable transport tool for power construction provided by an embodiment of the present invention comprises a traveling mechanism 1 and two lifting units 2 symmetrically arranged on both sides of the traveling mechanism 1, wherein it should be noted that the traveling mechanism 1 is a prior art, which may be a cart, and the wheels of the cart may be driving wheels; each lifting unit 2 comprises a moving frame 201, a second driving member 202 and two clamping assemblies 203, the moving frame 201 is slidably connected to the traveling mechanism 1, and the two clamping assemblies 203 are both slidably connected to the moving frame 201; a first driving member 3 is provided on the traveling mechanism 1, and the first driving member 3 is used to drive the moving frames 201 of the two lifting units 2 to slide apart relative to the traveling mechanism 1, so that the clamping assemblies 203 of the two lifting units 2 are respectively aligned with the two side discs of the cable drum; the second driving member 202 of each lifting unit 2 is used to drive its two clamping assemblies 203 to slide and close on the moving frame 201 to clamp and lift the corresponding side discs of the cable drum. It should be noted that the first driving member 3 drives the two moving frames 201 to slide in the direction of the X axis, and each second driving member 202 drives the two clamping components 203 on the corresponding moving frame 201 to slide in the direction of the Y axis, and the X axis is perpendicular to the Y axis.

[0030] Specifically, when the traveling mechanism 1 is located directly below the cable drum, the first driving member 3 is used to drive the two moving frames 201 to synchronously slide in the opposite direction so that the two moving frames 201 are away from the traveling mechanism 1, so that the two clamping components 203 of each lifting unit 2 can be located directly below the corresponding side drum of the cable drum, and then the two clamping components 203 of the corresponding lifting unit 2 are synchronously driven to close together by the second driving members 202, and in the closing stroke, they can first abut against the edge of the corresponding side drum of the cable drum, and then continue to close to squeeze the side drum of the cable drum to lift the entire cable drum. The entire operation process can achieve the effect of lifting the cable drum wound with the cable, without the need for lifting equipment such as forklifts to load it onto the traveling mechanism 1, which not only greatly improves the practicality of the entire device, but also avoids the risk of manual handling by staff, and the traveling mechanism 1 can achieve the effect of transporting the cable drum.

[0031] Each clamping assembly 203 includes: a sliding arm 2031, a first clamping seat 2032 and a first rotating roller 2034. The sliding arm 2031 is slidably connected to the mobile frame 201; the first clamping seat 2032 is fixedly connected to the sliding arm 2031, and a first limiting cavity 2033 is provided on the first clamping seat 2032 for the corresponding side disk of the cable drum to be clamped; and both ends of the first rotating roller 2034 are rotatably connected to the inner wall of the first limiting cavity 2033. The diameter of the first rotating roller 2034 is gradually reduced from both sides to the center of the axis. A plurality of annular anti-skid patterns are provided on the first rotating roller 2034, and the diameters of the plurality of anti-skid patterns are gradually reduced from both sides to the center of the axis. Specifically, when each clamping assembly 203 is located directly below the corresponding side disk of the cable drum, the two sliding arms 2031 on each movable frame 201 are driven by the corresponding second driving member 202 and close to each other, so that the first clamping seat 2032 on the two sliding arms 2031 is close to the edge of the corresponding side disk of the cable drum, until the two side disks of the cable drum are located in the first limiting cavity 2033 corresponding to the first clamping seat 2032 and abut against the first rotating roller 2034. At this time, the second driving member 202 continues to drive the two sliding arms 2031 on each movable frame 201 to continue to close, thereby forcing the two adjacent first rotating rollers 2034 on each movable frame 201 to squeeze the corresponding side disk of the cable drum, thereby achieving the effect of lifting the entire cable drum. Among them, the first limiting cavity 2033 is arranged in an arc shape, so that when the side disc of the cable drum is located in the corresponding first limiting cavity 2033, it can prevent the side disc of the cable drum from being separated from the first clamping seat 2032, thereby improving the safety to a certain extent; and the first rotating roller 2034 is arranged so that during the transportation process, the corresponding side disc of the cable drum abutting on the first rotating roller 2034 can be prevented from sliding in the axial direction relative to the first rotating roller 2034 through friction, thereby improving the stability during transportation to a certain extent. Among them, it should be noted that when paying out the line, the cable drum will rotate, and the two first rotating rollers 2034 corresponding to the two side discs of the cable drum can rotate relative to the corresponding sliding arm 2031 due to friction, thereby completing the paying out or winding operation, and at the same time, the first rotating rollers 2034 abutting on the two side discs of the cable drum can reduce the cable drum from being separated from the first clamping seat 2032. Based on this, Figure 1 As shown, in the present invention, a rotating motor 10 can be fixedly connected to one of the first clamping seats 2032, and the output shaft of the rotating motor 10 is coaxially fixedly connected to the corresponding first rotating roller 2034. Therefore, when releasing the wire, the rotating motor 10 drives the corresponding first rotating roller 2034 to rotate, and with the cooperation of other rotating rollers, the cable drum can be driven to rotate, so that the entire device can have a function of winding or unwinding the cable, which improves the practicality of the entire device to a certain extent. Among them, a plurality of auxiliary universal wheels are provided at the bottom of each sliding arm 2031, which play a supporting role after lifting the cable drum.

[0032] The first driving member 3 is a first bidirectional cylinder, which is fixedly connected to the walking mechanism 1. The two hydraulic rods of the first bidirectional cylinder are slidably connected to the two moving frames 201 through the first sliding part 4 in a one-to-one correspondence. A locking member for locking the two sliding arms 2031 is provided between each first sliding part 4 and the corresponding two sliding arms 2031. It should be noted that each first sliding part 4 includes a connecting frame fixedly connected to the corresponding hydraulic rod of the first bidirectional cylinder, and two sliders are fixedly connected to the connecting frame, and the corresponding moving frame 201 is provided with a first slide groove for the slider to slide. Based on this, when the two hydraulic rods of the first bidirectional cylinder are switched from a fully retracted state to an extended state, each slider slides along the corresponding first slide groove until the side of each slider away from the moving frame 201 abuts against the inner wall of the first slide groove. At this time, when the slider continues to extend, the two hydraulic rods will synchronously push the two moving frames 201 to synchronously slide in the opposite direction along the X-axis to move away from the walking mechanism 1.

[0033] Each second driving member 202 is a second bidirectional cylinder, the first bidirectional cylinder is fixedly connected to the walking mechanism 1, and the two hydraulic rods of each second bidirectional cylinder are fixedly connected to the two sliding arms 2031 of the corresponding lifting unit 2 in a one-to-one correspondence. The two second bidirectional cylinders act on the two clamping components 203 of the corresponding lifting unit 2 at the same time, that is, each bidirectional cylinder can drive the two sliding arms 2031 of each lifting unit 2 to separate or approach.

[0034] Among them, the locking member includes two locking units 5, each locking unit 5 includes: a wedge-shaped latch 501, a socket 502 and a compression spring 503, the wedge-shaped latch 501 is slidably connected to the sliding arm 2031, and the inclined surface of the wedge-shaped latch 501 faces the first sliding part 4; the socket 502 is opened on the first sliding part 4; the compression spring 503 is sleeved on the wedge-shaped latch 501, and one end of the compression spring 503 is fixedly connected to the second sliding part, and the other end is fixedly connected to the wedge-shaped latch 501, and the compression spring 503 can drive the wedge-shaped latch 501 to be inserted into the socket 502 during the stroke of restoring elastic deformation. Specifically, when the second bidirectional cylinder of each lifting unit 2 drives the corresponding two clamping assemblies 203 to synchronously slide in opposite directions along the Y-axis and close, that is, the two sliding arms 2031 of each lifting unit 2 will be driven by the second bidirectional cylinder to synchronously slide and close. Based on this, in the closing stroke, the wedge surface of the wedge pin 501 will conflict with the first sliding part 4, thereby forcing the wedge pin 501 to slide relative to the sliding arm 2031 along the X-axis until the wedge pin 501 is aligned with the socket 502 on the second sliding part. At this time, each return spring can drive the corresponding wedge pin 501 to be inserted into the socket 502 when restoring the elastic deformation, so that each sliding arm 2031 is locked on the corresponding first sliding part 4. Based on this, when each sliding arm 2031 is locked with the corresponding first sliding part 4, if the two second bidirectional cylinders are damaged, the two hydraulic rods of each second bidirectional cylinder can be restricted from sliding, thereby restricting the two sliding arms 2031 of each lifting unit 2 from separating, thereby preventing the cable drum from falling, and enhancing the safety of the entire device to a certain extent. It should be noted that the width of the first limiting cavity 2033 is less than the distance that the first sliding part 4 slides along the first slide groove. When the first bidirectional cylinder is damaged, the first limiting cavity 2033 can restrict the cable drum from detaching from the first clamping seat 2032, and the first rotating roller 2034 located in the first limiting cavity 2033 can reduce the risk of the cable drum sliding axially along the first rotating roller 2034 in the first limiting cavity 2033, so that the cable drum will not detach from the first clamping seat 2032, thereby further improving the safety of the entire device.

[0035] Specifically, when the cable drum needs to be unloaded, the first bidirectional cylinder will first drive the two first sliding parts 4 to slide on the corresponding moving frame 201 until each wedge-shaped pin 501 is disengaged from the corresponding socket 502, and then the second bidirectional cylinder will drive the two sliding arms 2031 of each lifting unit 2 to separate to make the cable drum fall, and the two sliding arms 2031 of each lifting unit 2 need to be away from the edge of the corresponding side disk of the cable drum, and finally the first bidirectional cylinder drives the two moving frames 201 to close and abut against the side wall of the walking mechanism 1. In summary, in the present invention, a controller is also provided in the entire device, wherein the first bidirectional cylinder and the two second bidirectional cylinders are electrically connected to the controller, and the above-mentioned first cylinder and the two second cylinders work in coordination under the control of the controller.

[0036] As another embodiment of the present invention, Figure 7 - Fig.10 As shown, each clamping assembly 203 includes: a sliding arm 2031, which is slidably connected to the mobile frame 201; a first clamping seat 2032, which is vertically elastically slidably connected to the sliding arm 2031, and the first clamping seat 2032 is provided with a first limiting cavity 2033 for the corresponding side disk of the cable drum to be clamped; a first rotating roller 2034, both ends of which are rotatably connected to the inner wall of the first limiting cavity 2033, wherein the structure and function of the first rotating roller 2034 are the same as those of the above-mentioned first rotating roller 2034; a second clamping seat 6, which is rotatably connected to the sliding arm 2031 through an extension rod; to There is one less connecting rod 7, one end of which is rotatably connected to the first clamp seat 2032, and the other end of which is rotatably connected to the second clamp seat 6; a positioning member 8, which is used to lock the first clamp seat 2032; an unlocking rod 9, which is fixedly connected to the mobile frame 201, and can drive the positioning member 8 to unlock in the path where the sliding arm 2031 slides relative to the mobile frame 201; the two first clamp seats 2032 of each lifting unit 2 accept the dead weight of the cable drum to force the first clamp seat 2032 to slide vertically relative to the sliding arm 2031, and drive the second clamp seat 6 to rotate relative to the sliding arm 2031 through the connecting rod 7 to press against the side plate of the cable drum. It should be noted that a second limiting cavity is opened on each second clamp seat 6, and a second rotating roller is also rotatably connected in the second limiting cavity, and the structure of the second rotating roller is consistent with that of the first rotating roller 2034.

[0037] Each positioning member 8 includes: a positioning rod 801, which is slidably connected to the corresponding sliding arm 2031; a positioning hole 802, which is provided on the corresponding first clamping seat 2032; a first spring 803, one end of which is fixedly connected to the positioning rod 801 and the other end of which is fixedly connected to the sliding arm 2031; in the path where the sliding arm 2031 slides relative to the moving frame 201, the unlocking rod 9 can abut against the positioning rod 801 to force the positioning rod 801 to slide relative to the sliding arm 2031 so that the positioning rod 801 is separated from the positioning hole 802. A second sliding groove is provided on each sliding arm 2031, and each positioning rod 801 slides in the second sliding groove along the Y-axis direction, and the first spring 803 is located in the second sliding groove.

[0038] Specifically, when the second driving member 202 of each lifting unit 2 drives the corresponding two sliding arms 2031 to slide, each positioning rod 801 is located in the corresponding positioning hole 802 to prevent the first clamping seat 2032 from sliding vertically relative to the corresponding sliding arm 2031. When the first rotating rollers 2034 of the two first clamping seats 2032 of each lifting unit 2 abut against the side discs corresponding to the cable drum and force the cable drum to be lifted to a certain height, the unlocking rod 9 will conflict with the positioning rod 801, and when the two sliding arms 2031 of each lifting unit 2 continue to slide, each unlocking rod 9 can prevent the corresponding positioning rod 801 from sliding. The arm 2031 continues to slide and drives the positioning rod 801 to compress the first spring 803, so that the positioning rod 801 disengages from the corresponding positioning hole 802, thereby completing the unlocking of each first clamping seat 2032; thereafter, the cable reel that has been lifted to a certain height drives each first clamping seat 2032 to move vertically downward synchronously under its own weight, and each first clamping seat 2032 can drive the second clamping seat 6 connected to the corresponding sliding arm 2031 to rotate through each connecting rod 7 until the second rotating roller of the second clamping seat 6 abuts against the side edge of the cable reel, thereby completing the locking of the cable reel and improving the stability of the cable reel during transportation.

[0039] Among them, an elastic telescopic rod 11 is provided between each first clamp seat 2032 and the corresponding sliding arm 2031. When the cable reel is unloaded, the positioning rod 801 is separated from the unlocking rod 9, and the elastic telescopic rod 11 drives the first clamp seat 2032 to move vertically upward during the process of restoring the elastic deformation, until the first spring 803 restores the elastic deformation and drives the positioning rod 801 to be inserted into the positioning hole 802, thereby completing the locking of the first clamp seat 2032, which is facilitating the subsequent transportation of other cable reels.

[0040] In summary, in another embodiment of the present invention, a rotating motor 10 can also be fixedly connected to one of the first clamping seats 2032, and the output shaft of the rotating motor 10 is also coaxially fixedly connected to the first rotating roller 2034 of the first clamping seat 2032, so the function of the rotating motor 10 is the same as the above-mentioned rotating motor 10. So far, when the second clamping seat 6 abuts against the side disc of the cable drum, it abuts against the side disc through the second rotating roller. Therefore, when the output shaft of the rotating motor 10 rotates to drive the corresponding first rotating roller 2034 to rotate, the cable drum can be driven to rotate, and the first rotating roller 2034 can reduce the friction between the cable drum and the second clamping seat 6 during the rotation process, so as to achieve better unwinding or rewinding of the cable.

[0041] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
