detailed description

The present invention provides a clamping obstacle-crossing device for a horizontal double-split high-voltage transmission line deicer. Figure 1 is a schematic structural view of a specific embodiment of the present invention, and Figure 3 is a structure of the specific embodiment in Figure 1 when it is applied to a deicer schematic diagram. As shown in FIG. 3 , the present invention is applied to a horizontal double-split high-voltage transmission line deicer, which specifically includes a knocking deicing device 2, a milling deicing device 16 and a clamping obstacle surmounting device 1. The horizontal double-split high-voltage transmission line deicing machine combines the three mechanical deicing methods of knocking deicing, milling deicing and clamping deicing to realize compound deicing. Deicing the two wires at the same time can significantly improve the deicing effect and efficiency.

With reference to Fig. 1, shown in Fig. 3, clamping obstacle-surmounting device 1 comprises frame 3, traveling wheel set and clamping wheel 7. The traveling wheel set comprises a front traveling wheel set and a rear traveling wheel set, the front traveling wheel set comprises two coaxial front traveling wheels 5, and the rear traveling wheel set comprises two coaxial rear traveling wheels 6. Front and rear traveling wheels 5,6 are all installed below the frame 3 by a support member 8. The clamping wheel 7 is positioned at the front traveling wheel 5 or the rear traveling wheel 6 below which is set correspondingly, and the outer ends of the axles of the front and rear two clamping wheels 7 on the same side are fixedly connected with vertical rods 13 respectively, and the upper ends of the two vertical rods 13 Fixedly connected by a horizontal shaft 12, the horizontal shaft 12 on the same side, the vertical rod 13 and the clamping wheel shaft are connected as a whole. Vertical chute 9 is welded to the corresponding positions on the front and back sides of the frame 3 bottom, and a slide block 10 is arranged in each chute, and an elastic member is installed between the slide block 10 and the bottom of the vertical chute 9 . The transverse axis 12 passes through the slide blocks 10 in the front and rear vertical chute 9 on the same side.

The front and rear traveling wheels 5,6 on both sides below the frame 3 are arranged symmetrically, and ride on the top of the wire 1. The clamping wheels 7 are positioned below the guide wire 1 and are mounted on respective axles through bearings. Each clamping wheel 7 is paired with the corresponding traveling wheel to clamp the wire 1 respectively. The front and rear traveling wheels 5, 6 cooperate with the corresponding clamping wheels 7 to walk on the guide wire 1, so that the deicer can be stably erected on the guide wire 1, improve the operation stability, and ensure that the deicer will not fall. The slider 10 can slide up and down along the vertical chute 9 under the action of the elastic member, thereby driving the horizontal shaft 12 to move up and down relative to the frame 3, and finally realize the two clamping wheels 7 on the same side to move up and down relative to the frame 3.

The elastic member in the vertical chute 9 is preferably a spring 11, and the spring 11 is in a compressed state in an initial state. During the initial operation, the deicing machine is erected above the two wires 1 arranged horizontally, and the weight of the whole machine makes the front road wheels 5 and the rear road wheels 6 press the wires 1 downward. The springs 11 in the two vertical slide grooves 9 on the same side push the slider 10 to move upward, thereby driving the clamping wheel 7 to move upward through the horizontal shaft 12, so that the clamping wheel 7 is further close to and presses the wire 1 upward. Therefore, during the running process of the deicing machine, the two-way clamping force of the front and rear traveling wheels 5, 6 and the corresponding clamping wheels 7 on the wire 1 realizes pinching and deicing.

When the deicer ran into the spacer bar, under the drive of the traction mechanism 4, the front and rear road wheels 5,6 of the clamping obstacle surmounting device 1 were driven to contact with the spacer bar top, and at the same time, with the front and rear road wheels 5,6 Cooperating clamping wheel 7 is in contact with the spacer bar bottom. Under the further action of the driving force, the spacer bars force the integral structure formed by the clamping wheel 7 on the same side, the vertical bar 13 and the transverse shaft 12 to move downward as a whole, thereby forcing the slider 10 on the same side to move downward in the vertical chute 9 movement, compressing the spring 11 further. After the de-icing machine completes the spacer bar to overcome the obstacle, the distance between the front and rear road wheels 5, 6 and the corresponding clamping wheel 7 decreases, and the deformation of the spring 11 in the vertical chute 9 decreases accordingly, returning to the initial state. The amount of deformation in the working state ensures the clamping force of the clamping wheel 7 and the front and rear travel wheels 5 and 6 to the wire 1.

In order to facilitate the loading and unloading of the high-altitude operation of the deicing machine, in a specific embodiment, a cam 15 is fixed on the upper end of the vertical bar 13 clamping the obstacle breaking device 1, with reference to Fig. 1, Fig. 2, Fig. 3, the outline of the cam 15 The curved surface and the bottom surface of the frame 3 are in plane high pair contact, and the two ends of the transverse axis 12 are fixedly connected with the wheel shafts of the front and rear cams 15 of the same side respectively. Thus in the loading and unloading process, the clamping wheel 7 on the same side of the clamping obstacle surmounting device 1 can be turned outwards. The axles of the two cams 15 on the same side are fixedly connected, the cam 15 on the upper end of the vertical rod 13 and the bottom surface of the frame 3 form a plane high pair, and the horizontal shaft 12 and the two sliders 10 on the same side form a rotating pair, so when the clamping wheel 7 is turned over, Drive the cam 15 and the transverse shaft 12 to rotate relative to the frame 3 and the slide block 10 respectively, which can avoid the clamping wheel 7 and other components from interfering with the wire 1 and avoid operating accidents.

In order to limit the flipped pinch wheel 7 during the loading and unloading process of the deicer, in a specific embodiment, a limiter is provided on the end surface of the cam 15 near the side of the vertical chute 9, and the limiter and Vertical chute 9 surface contacts. When the clamping wheel 7 was in working condition, the upper limit member of the cam 15 opened the limit groove one corresponding to the surface position of the vertical chute 9 . Now the limiter on the cam 15 is embedded in the limit groove one, the limit cam 15 rotates, and the deicer with the clamping obstacle surmounting device 1 is in a stable walking state. When the clamping wheel 7 was in the open state, the upper limit member of the cam 15 opened the second limit groove corresponding to the surface position of the vertical chute 9 . Now the limiter on the cam 15 embeds in the limit groove two, the further rotation of the limit cam 15, and the de-icer with the clamping obstacle surmounting device 1 is in the loading and unloading state.

The aforementioned limiting member is preferably a limiting pin or a limiting ball. The cooperation between the limiter and the limit grooves one and two ensures that no matter the deicer is in operation or loading and unloading state, the clamping obstacle surmounting device 1 will not be connected with the plane high pair of the bottom surface of the frame 3 due to the cam 15, and then affect the corresponding clip. The clamping force of the clamping wheel 7 and the front and rear traveling wheels 5 and 6 on the wire 1, or the inversion of the clamping wheel 7 is not in place during the loading and unloading process, and the overturning angle of the clamping wheel 7 changes during the loading and unloading process, resulting in excessive loading and unloading efficiency. Low or work accidents.

In some cases, it is also possible to set the front and rear walking wheel sets as driven wheel sets, and separately set the driving device to drive the front walking wheel set and the rear walking wheel set to walk in the same direction, so as to realize the removal of obstacles with clamping device 1. The ice machine works normally.

In various embodiments of the present invention, in order to improve the clamping effect of the front and rear traveling wheels 5,6 and the corresponding clamping wheels 7 on the wire 1, and avoid the front and rear traveling wheels 5,6 and the corresponding clamping wheels 7 The rims of the rims interfere with each other, and the clamping wheel 7 can be arranged on the corresponding front road wheel 5 or the rear road wheel 6 below the staggered or staggered position, with reference to Fig. 1 and shown in Fig. The efficiency of the deicer.

In various embodiments of the present invention, the traveling wheel set can be provided with more than two sets of wheels along its traveling direction, including a front traveling wheel group, a middle traveling wheel group, and a rear traveling wheel group.
