Description

Technical Field

[0001] The utility model relates to a deicing device, in particular to a clamping mechanism for an overhead transmission line deicing device. Background Art

[0002] Currently, mechanical deicing mechanisms generally include components such as a housing, a traveling mechanism, and a clamping mechanism that cooperates with the traveling mechanism to clamp the overhead transmission line, such as CN202020944541.0. In order to clamp the overhead transmission line, the clamping mechanism of the existing device is generally arranged directly below the traveling mechanism. To facilitate the hoisting of the deicing mechanism onto the line by a drone, the inlet section of the overhead transmission line is generally set in the vertical direction. At the same time, to avoid the clamping mechanism interfering with the entry of the overhead transmission line from the inlet, the inlet is generally arranged in an arc shape on the frame structure. Although this method can avoid the interference of the clamping mechanism, due to the transmission line being at a high altitude, there are certain blind spots when remotely controlling the drone. When hoisting the deicing mechanism onto the line, the angle of the mechanical deicing mechanism needs to be adjusted repeatedly to enable the drone to carry the overhead transmission line through the arc-shaped inlet and enter the interior of the deicing mechanism, making the operation of hoisting the deicing mechanism onto the line more difficult. Summary of the Utility Model

[0003] Aiming at the above deficiencies in the prior art, the clamping mechanism for an overhead transmission line deicing device provided by the utility model solves the problem that the existing clamping mechanism is unreasonably designed, resulting in difficult hoisting of the deicing device onto the line.

[0004] To achieve the above invention purpose, the technical solution adopted by the present invention is as follows:

[0005] Provide a clamping mechanism for an overhead transmission line deicing device, which includes a first telescopic mechanism and a second telescopic mechanism rotatably connected to the accommodation box of the overhead transmission line deicing device. A clamping wheel platform cooperating with the traveling mechanism is fixed at the top of the first telescopic mechanism. The second telescopic mechanism is hinged to the first telescopic mechanism to drive the first telescopic mechanism to rotate. Both the first telescopic mechanism and the second telescopic mechanism are electrically connected to the control module.

[0006] Further, the clamping wheel platform includes a mounting plate and a support plate fixedly connected to the first telescopic mechanism. "C"-shaped brackets are fixed on both sides of the mounting plate. The two cross plates of one bracket cooperate with the opposite cross plates of the other bracket to rotatably mount clamping wheels that cooperate with both sides of the traveling wheels. The support plate is fixedly connected with a guide rod slidably connected to the mounting plate, and a spring is sleeved on the guide rod between the support plate and the mounting plate.

[0007] Further, connection frames fixedly connected to the top end of the first telescopic mechanism are arranged on both sides of the support plate. The included angle between the two connecting arms of the connection frame is an obtuse angle. The guide rod is parallel to the first telescopic mechanism.

[0008] Furthermore, the maximum height of the clamping wheel is lower than the height of the first telescopic mechanism.

[0009] Furthermore, both the first telescopic mechanism and the second telescopic mechanism are electric push rods.

[0010] Furthermore, the clamping mechanism for the overhead transmission line de-icing device further includes a mounting bracket rotatably connected to the bottom plate of the accommodating box. The first telescopic mechanism is fixed on the mounting bracket, and the second telescopic mechanism is hinged to the mounting bracket.

[0011] Furthermore, the clamping mechanism for the overhead transmission line de-icing device further includes a connecting plate fixed on the bottom plate of the accommodating box. A convex block hinged to the bottom end of the mounting bracket is arranged on the connecting plate, and the second telescopic mechanism is hinged to one end of the connecting plate away from the convex block.

[0012] The beneficial effects of the present utility model are as follows: In this solution, the first telescopic mechanism is rotatably connected to the installation structure (accommodating box), and then rotatably connected to the second telescopic mechanism rotatably connected to the accommodating box. After such a setting, when the de-icing device needs to be put on the line, the second telescopic mechanism can drive the first telescopic mechanism and the clamping wheel platform thereon to rotate a certain angle, so that the first telescopic mechanism and the clamping wheel platform deviate from the traveling mechanism by a certain distance, thus creating a space directly below the traveling mechanism. The entrance formed by the space directly below the traveling mechanism is relatively large, facilitating the quick on-line operation of the de-icing device. Description of the Drawings

Detailed implementation manners

[0019] The following describes the detailed implementation manners of the present utility model to facilitate those skilled in the art to understand the present utility model. However, it should be clear that the present utility model is not limited to the scope of the detailed implementation manners. For those of ordinary skill in the art in the technical field, as long as various changes are within the spirit and scope of the present utility model defined and determined by the appended claims, these changes are obvious, and all utility models created using the concept of the present utility model are within the scope of protection.

[0020] As Figure 2 、 3 and Figure 5 shown, the clamping mechanism 3 of the de-icing device provided in this solution includes a first telescopic mechanism 31 and a second telescopic mechanism 32 that are rotatably connected to the storage box 1. In this solution, it is preferably that both the first telescopic mechanism 31 and the second telescopic mechanism 32 are electric push rods for easy electric control.

[0021] For the specific structure of the de-icing device to which the clamping mechanism 3 of this solution is applied, reference can be made to Figure 1 , the clamping mechanism 3 of this solution cooperates with the traveling mechanism 2 of the overhead transmission line de-icing device, and the traveling mechanism includes a motor 21 and a traveling wheel 22 connected to the output shaft of the motor 21.

[0022] As Figures 2 to 5 shown, a clamping wheel platform 33 that cooperates with the traveling mechanism 2 is fixed to the top of the first telescopic mechanism 31, and the second telescopic mechanism 32 is hinged to the first telescopic mechanism 31 to drive the first telescopic mechanism 31 to rotate; a sliding groove for the first telescopic mechanism 31 to extend and slide along the top plate is provided on the top plate of the storage box 1; both the first telescopic mechanism 31 and the second telescopic mechanism 32 are electrically connected to the control module.

[0023] Before the de-icing device is put on the line, it is necessary to use the second telescopic mechanism 32 to drive the first telescopic mechanism 31 to rotate by a certain angle, and the first telescopic mechanism 31 drives the clamping wheel platform 33 thereon to deviate from the traveling mechanism 2 that cooperates with it; after the de-icing device is hung on the transmission line cable, the second telescopic mechanism 32 drives the first telescopic mechanism 31 to return to its original position until the second telescopic mechanism 32 is parallel to the vertical plane, and then the first telescopic mechanism 31 is started to drive the clamping wheel platform 33 to move upward until it contacts the overhead transmission line.

[0024] AsFigure 4 As shown, the clamping wheel platform 33 includes a mounting plate 331 and a support plate 332 fixedly connected to the first telescopic mechanism 31. On both sides of the mounting plate 331, "C"-shaped brackets 333 are fixed. The two cross plates 3331 of one bracket 333 cooperate with the opposite cross plates 3331 on the other bracket 333, and clamping wheels 336 that cooperate with both sides of the traveling mechanism 2 are rotatably installed; a guide rod 334 fixedly connected to the support plate 332 and slidably connected to the mounting plate 331 is provided on the support plate 332, and a spring 335 is sleeved on the guide rod 334 between the support plate 332 and the mounting plate 331.

[0025] During the de-icing operation, the guide rod 334 can limit the mounting plate 331 to prevent the mounting plate 331 from shaking with the clamping wheels 336, so as to reduce the stability of the de-icing device during de-icing; the setting of the spring 335 can consume the vibration force transmitted through the clamping wheels 336 during the de-icing operation, so as to prevent this force from being transmitted to the entire housing through the clamping mechanism 3, causing the de-icing device to shake and affecting the transmission distance of the vibration force on the overhead transmission line.

[0026] Connection frames 337 fixedly connected to the top of the first telescopic mechanism 31 are provided on both sides of the support plate 332, and the included angle between the two connecting arms of the connection frame 337 is an obtuse angle; the guide rod 334 is parallel to the first telescopic mechanism 31. The inclined connecting arms can make the height of the support plate 332 lower than the height of the first telescopic mechanism 31. In this way, after the clamping wheel platform 33 is installed, the overall height of the clamping mechanism 3 can be reduced.

[0027] In addition, when the two connecting arms cooperate and cooperate with the clamping wheels 336, the first telescopic mechanism 31 parallel to the vertical plane is still deviated from the traveling mechanism 2. After the second telescopic mechanism 32 drives the first telescopic mechanism 31 to rotate a certain angle, the non-movable end of the first telescopic mechanism 31 is still deviated from the traveling mechanism 2, that is, it can ensure that the clamping mechanism 3 does not occupy the entrance and ensure the size and smoothness of the entrance.

[0028] During implementation, it is preferably that the maximum height of the clamping wheels 336 is lower than the height of the first telescopic mechanism 31 in this solution. In this way, the overall height of the clamping mechanism 3 can be no greater than the height of the first telescopic mechanism 31, making the overall center of gravity relatively low. While ensuring stability, the shaking of the de-icing under vibration can be reduced.

[0029] Such as Figure 2 、 Figure 3 and 5As shown, a mounting bracket 338 is rotatably connected to the bottom plate of the accommodation box 1. The first telescopic mechanism 31 is fixed to the mounting bracket 338, and the second telescopic mechanism 32 is hinged to the mounting bracket 338. The mounting bracket 338 can increase the connection points between the clamping mechanism 3 and the accommodation box 1 to ensure the stability of the installation. At the same time, it can also provide a connection point for the second telescopic mechanism 32 to facilitate the realization of the rotational connection between the second telescopic mechanism 32 and the first telescopic mechanism 31.

[0030] In summary, through the cooperation of the first telescopic mechanism and the second telescopic mechanism, this solution can move the first telescopic mechanism and the clamping wheel platform 33 thereon away from the traveling mechanism by a certain distance, so that the entrance formed in the space directly below the traveling mechanism is relatively large, facilitating the quick online operation of the deicing device.
