Description

TECHNICAL FIELD

[0001] The application relates to the technical field of deicing of power transmission cables, and discloses a handheld rod type snow sweeper for contact lines. BACKGROUND

[0002] The contact line is the source of traction power for electrified railways and rail transit electric passenger cars, and the rapid snow sweeping and deicing of the open air wire net is a necessary condition for ensuring the normal operation of the overhead contact system equipment. The existing snow sweeping and deicing tools for the overhead contact system are mainly based on local deicing by knocking, beating and hooking, and have low efficiency in removing large-area ice and snow on the outdoor wire net, high requirement for personnel physical strength and certain danger.

[0003] A utility model patent with the application number 202420462168.3 discloses a suspension type contact line deicing device, which comprises a supporting rod and a deicing mechanism installed at the end of the supporting rod. The deicing mechanism comprises a limiting plate, which is installed at the top of the supporting rod in the longitudinal direction and located on the side of the supporting rod. A suspension pulley is installed at the upper end of the limiting plate and used for being suspended at the top of the contact line. The suspension pulley is located on the two sides of the supporting rod. A supporting plate is installed at the lower end of the limiting plate and located on the same side of the suspension pulley. The supporting plate is installed on the limiting plate in an inclined manner. A deicing plate is installed on the supporting plate. Compared with the conventional snow sweeping and deicing tools mainly based on local deicing by knocking, beating and hooking, the suspension type contact line deicing device disclosed by the patent does not require an operator to hold up the supporting rod, and only needs to apply a pushing force to the supporting rod to realize the deicing operation on the contact line, thereby saving more manpower cost. However, the deicing device has the following problems. On the one hand, the deicing device only has the function of deicing the contact line and cannot sweep the snow on the upper end of the contact line. On the other hand, the deicing device can only process the ice on the contact line through the scraping action of the deicing plate. When encountering large pieces of hard ice, it is difficult to effectively clean the large pieces of hard ice only by the scraping action of the deicing plate, and the operator needs to use other tools for auxiliary processing by knocking, beating and the like, thereby increasing the operation difficulty and convenience of deicing. Therefore, in view of the above problems of the existing suspension type contact line deicing device, the application provides a handheld rod type snow sweeper for contact lines, which can effectively solve the above technical problems. SUMMARY

[0004] The application aims to solve the technical problems and deficiencies of the existing suspension type contact line deicing device, such as low efficiency, single function, insufficient ice breaking capacity and high labor intensity of personnel.

[0005] The application is realized by the following technical scheme. The utility model provides a handheld pole type snow and ice remover for contact wire, which comprises a snow and ice removing mechanism, an insulating pole and a handheld pole connected in sequence, the snow and ice removing mechanism comprises a seat frame, a pulley for hanging and rolling along the contact wire is arranged on the upper end of the seat frame, a broken ice shovel plate is rotatably connected to the seat frame below the pulley through a convex shaft and a torsional spring, the front end of the broken ice shovel plate is kept upward and in contact with the lower end of the contact wire under the action of the torsional spring, and a brushing assembly for brushing off the snow on the upper end of the contact wire is arranged above the broken ice shovel plate.

[0006] As a further arrangement of the above-mentioned scheme, the snow and ice remover further comprises a manual impact mechanism for driving the broken ice shovel plate to impact the contact wire to break ice. The manual impact mechanism comprises a slide way arranged in the insulating pole, an insulating slide block slidably arranged in the slide way, a first pull rope and a second pull rope, one end of the first pull rope is connected to the insulating slide block, the other end of the first pull rope is guided by a guide pulley arranged on the seat frame and connected to the broken ice shovel plate near the half-ring blade, one end of the second pull rope is connected to the insulating slide block, the other end of the second pull rope extends out of the lower end of the slide way and is connected to a pulling operation member.

[0007] As a further arrangement of the above-mentioned scheme, the snow and ice remover further comprises an automatic knocking mechanism for intermittently knocking the contact wire during travel. The automatic knocking mechanism comprises a pressing rotating disc coaxially fixedly connected to the pulley and a swing lever rotatably mounted on the side end of the seat frame through a connecting shaft, a pressing protrusion is arranged on the outer circular surface of the pressing rotating disc, one end of the swing lever is provided with a beveled end matched with the pressing protrusion, and the other end of the swing lever is fixedly provided with a knocking rod located above the contact wire.

[0008] As a further arrangement of the above-mentioned scheme, the distance between the knocking rod and the connecting shaft is greater than the distance between the beveled end and the connecting shaft, so that the swing lever forms a lever structure with the connecting shaft as a fulcrum.

[0009] As a further arrangement of the above-mentioned scheme, a limiting block is arranged on the seat frame to limit the initial swing amplitude of the swing lever.

[0010] As a further arrangement of the above-mentioned scheme, the brushing assembly comprises a connecting strip plate connected to the upper end of the seat frame, and a hard brush wire is arranged at the lower end of the connecting strip plate.

[0011] As a further arrangement of the above-mentioned scheme, the insulating pole is rotatably connected to the handheld pole, two supporting plates are arranged at the lower end of the insulating pole, a shaft is arranged between the two supporting plates, and a rotating connecting block matched with the shaft is arranged at the upper end of the handheld pole.

[0012] As a further arrangement of the above-mentioned scheme, the seat frame and the insulating pole are detachably connected through a plug-in column and a locking bolt.

[0013] The core working principle of the device is "suspension walking, elastic pressurization and cooperative ice breaking". The suspension and walking are achieved by suspending the whole device on the contact line through the top pulley, and the operator can easily move the snow and ice remover along the contact line by pushing the operating rod on the ground. The elastic pressurization ice breaking is composed of an ice breaking shovel plate and a torsional spring, and the torsional spring provides a continuous and stable pressure to the bottom surface of the contact line, so that the front end of the ice breaking shovel plate can continuously and effectively scrape the ice on the bottom of the contact line during movement.

[0014] The cooperative ice breaking includes a basic mode and an enhanced mode, and the enhanced mode includes a manual impact mode and an automatic vibration mode. In the basic mode, the ice breaking shovel plate continuously scrapes the ice through elastic pressurization, and the snow sweeping assembly at the top cleans the snow on the line.

[0015] In the manual impact mode, when encountering large and hard ice, the operator can manually store energy through the impact generating mechanism (such as a pull ring, a pull rope and a sliding block mechanism) at the end of the operating rod to drive the ice breaking shovel plate to impact upward instantaneously, and break the hard ice by using the impact force of the half-ring blade.

[0016] In the automatic vibration mode, when the device is walking, the rotation of the pulley drives the pressure rotating disc and the lever mechanism to operate, so that the knocking rod can periodically and automatically knock the contact line, and shake off the firmly adhered ice by using the vibration effect.

[0017] Compared with the prior art, the present application has the following beneficial effects: The snow and ice remover disclosed in the present application integrates the functions of snow sweeping, mechanical ice breaking and vibration ice removing, and can clean the snow through the hard brush wire at the top, continuously scrape the thin ice through the torsional spring pressurized ice breaking shovel plate, and break the large and hard ice by using the manual impact mechanism or the automatic knocking mechanism, so that different forms of ice and snow can be efficiently and continuously removed, and the technical problems and deficiencies of the traditional tools, such as single function, poor snow and ice removing effect and low operation efficiency, are solved.

[0018] The snow and ice remover disclosed in the present application has strong ice breaking capacity and can effectively deal with various ice conditions. On the one hand, the torsional spring provides a constant contact pressure to the ice breaking shovel plate, ensuring that the half-ring blade continuously and effectively scrapes the ice on the bottom of the contact line; on the other hand, the added pull rope-sliding block mechanism allows the operator to manually store and release the ice breaking shovel plate when encountering hard and large ice, and break the hard ice by using the instantaneous impact force, thus solving the problem that the traditional scraper tool cannot handle large and hard ice; and on the third hand, the added lever type automatic knocking mechanism uses the self-rotation of the pulley during tool movement to drive the knocking rod to intermittently vibrate and knock the contact line, and uses the vibration effect to loosen the firmly adhered ice, so that the ice removing is more thorough.

[0019] The present application adopts a pulley suspension type design, the tool dead weight is borne by the contact line, the operator only needs to provide forward thrust and direction control, and labor intensity is greatly reduced; meanwhile, the insulation rod and the handheld rod adopt a hinged design, the operation angle can be flexibly adjusted according to the contact line slope, the adaptability is strong, and the operation difficulty is further reduced.

[0020] The snow and ice remover disclosed by the present application has simple overall structure, low manufacturing cost and convenient maintenance, is not only suitable for the contact line of electrified railway, but also can be popularized and applied to the deicing operation of urban rail transit, power transmission cable and bridge cable and the like, and has high popularization value and economic benefits.

DETAILED DESCRIPTION

[0023] In order to enable the personnel in the technical field to better understand the present application scheme, the technical solutions in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should belong to the scope of protection of the present application.

[0024] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings Figures 1-6 and in combination with the embodiments. Embodiment 1

[0025] The embodiment 1 discloses a handheld pole type snow and ice remover for contact line, referring to the attached drawings Figure 1 The main part of the snow and ice remover includes an upper and lower connected insulating pole 1 and a handheld pole 2, and a snow and ice removing mechanism 3 is connected to the top of the insulating pole 1.

[0026] Referring to the attached drawings Figure 2 The snow and ice removing mechanism 3 includes a seat frame 301 inserted into the top of the insulating pole 1, the lower surface of the seat frame 301 is provided with an insertion column 302 inserted into the insulating pole 1, and then the top of the insulating pole 1 is provided with a locking bolt 303 penetrating the through hole of the insertion column 302, so that the detachable connection between the seat frame 301 and the insulating pole 1 can be realized through the connecting effect of the locking bolt 303. A pulley 304 is rotatably arranged at the upper end of the seat frame 301, and a concave ring groove 3041 matched with the contact line 100 is formed on the wheel surface of the pulley 304, so as to realize the suspension positioning and walking guidance between the pulley 304 and the contact line 100.

[0027] A convex shaft 305 is arranged on the seat frame 301 directly below the pulley 304, a U-shaped ice breaking shovel plate 306 is rotatably connected to the convex shaft 305, and a torsion spring 307 is further sleeved on the convex shaft 305 and connected to the ice breaking shovel plate 306 and the seat frame 301 at both ends. A semi-ring cutting edge 3061 for breaking ice is formed at the front end of the ice breaking shovel plate 306 (i.e. in the forward direction), and an avoidance slot 3062 for passing through the contact line 100 is formed at the rear end of the ice breaking shovel plate 306. Then under the action of the torsion spring 307, the semi-ring cutting edge 3061 can stably contact the lower end of the contact line 100, so as to complete the moving ice breaking. In addition, a connecting strip plate 308 connected to the top of the seat frame 301 is arranged above the semi-ring cutting edge 3061, and a hard brush wire 309 capable of removing the snow on the upper end of the contact line 100 is arranged at the lower end of the connecting strip plate 308.

[0028] Finally, in the specific design, the insulating pole 1 and the handheld pole 2 in the embodiment 1 are connected by rotating connection. Two downward extending supporting plates 101 are arranged at the lower end of the insulating pole 1, and an axle 102 is arranged between the lower ends of the two supporting plates 101. A rotating connection block 201 extending upward is arranged at the upper end of the handheld pole 2, and an axle hole matched with the axle 102 is formed on the rotating connection block 201. Through the rotating connection of the insulating pole 1 and the handheld pole 2, the use angle between the insulating pole 1 and the handheld pole 2 can be adjusted by rotating in some special cases (for example, the contact line with a certain slope), so that the use effect of the snow and ice removing mechanism 3 can still be effectively ensured. Embodiment 2

[0029] The embodiment 2 discloses a hand-held rod type snow and ice sweeper for contact line which is further optimized based on the technical solution in the embodiment 1, and the same parts are not described again.

[0030] With reference to the accompanying drawings Figure 2 and the accompanying drawings Figure 3 , the embodiment 2 is provided with a wire guide 310 rotatably installed on the seat frame 301 below the ice breaking shovel plate 306, and a vertical sliding channel 103 is formed in the insulating rod 1. An insulating sliding block 311 is arranged in the sliding channel 103, which can be made of ultra-high molecular weight polyethylene, polyformaldehyde or polyamide, so that the insulating sliding block 311 has good insulation performance and certain self-lubricating property, thereby reducing the friction between the insulating sliding block 311 and the sliding channel 103. A first pull rope 312 is connected to the upper end of the insulating sliding block 311 and extends out of the upper end of the sliding channel 103, and then the first pull rope 312 is guided by the wire guide 310 and connected to the lower surface of the ice breaking shovel plate 306 near the side of the half-ring blade edge 3061. A second pull rope 313 is connected to the lower end of the insulating sliding block 311 and extends out of the lower end of the sliding channel 103, and then a pull ring 314 is connected to the second pull rope 313.

[0031] In the embodiment 2, when the snow and ice sweeper encounters a large piece of hard ice which is difficult to remove by the scraping action of the half-ring blade edge 3061 during use, the user can pull the pull ring 314 outward, and then the ice breaking shovel plate 306 is rotated by overcoming the action of the torsional spring 307 through the action of the second pull rope 313, the insulating sliding block 311 and the first pull rope 312. During the rotation of the ice breaking shovel plate 306, the half-ring blade edge 3061 moves away from the bottom wall of the contact line 100. Then, when the ice breaking shovel plate 306 rotates to a certain angle and the torsional spring 307 is fully charged, the pull ring 314 is released. At this time, the half-ring blade edge 3061 of the ice breaking shovel plate 306 will quickly rotate upward and hit the large piece of hard ice at the lower end of the contact line 100 under the action of the torsional spring 307, so that the large piece of hard ice is broken by the sharp edge of the half-ring blade edge 3061. Finally, the broken ice can be easily removed during the movement of the snow and ice sweeping mechanism 3. Embodiment 3

[0032] The embodiment 3 discloses a hand-held rod type snow and ice sweeper for contact line which is further optimized based on the technical solution in the embodiment 1 or the embodiment 2, and the same parts are not described again.

[0033] With reference to the accompanying drawings Figure 4 and the accompanying drawings Figure 5The inner recessed ring groove 3041 of the pulley 304 is coated with a rubber layer, thereby increasing the friction between the pulley 304 and the contact line 100. Meanwhile, a pressure rotating disc 320 is fixed concentrically at the rear end of the pulley 304, and 1-3 pressure protrusions 3201 are arranged on the outer surface of the pressure rotating disc 320. During the movement of the snow and ice remover along the contact line 100, the pulley 304 can drive the pressure rotating disc 320 at the rear end to rotate due to the stable friction provided by the rubber layer.

[0034] A side extension plate 315 is arranged on the seat 301 away from the half-ring blade edge 3061, and a connecting shaft 316 is fixed at the rear side of the side extension plate 315, and then a swing rod 317 is rotatably arranged on the connecting shaft 316. An inclined end of the swing rod 317 is arranged at the end close to the pressure rotating disc 320 and is used to act on the pressure protrusion 3201, and a knocking rod 318 is fixed at the other end of the swing rod 317 and extends forward and is located above the contact line 100. In the specific design, the distance between the knocking rod 318 and the connecting shaft 316 is greater than the distance between the inclined end and the connecting shaft 316, so that the swing rod 317 forms a lever structure with the connecting shaft 316 as the fulcrum. In addition, in order to avoid that the end of the knocking rod 318 is affected by gravity and causes the swing rod 317 to swing too much, a limiting block 319 is arranged at the rear side of the side extension plate 315 or the seat 301.

[0035] Through the above improved design, during the movement of the user holding the snow and ice remover along the contact line 100, the hard brush wire 309 can sweep the snow at the upper end of the contact line 100, the half-ring blade edge 3061 on the ice breaking shovel plate 306 can shovel the ice at the lower end of the contact line 100, and the rotation of the pulley 304 during the movement can drive the pressure rotating disc 320 to rotate, the pressure protrusion 3201 on the outer surface of the pressure rotating disc 320 can first act on the inclined end of the swing rod 317, the swing rod 317 is rotated, the knocking rod 318 is rotated upward to a certain height above the contact line 100, and then when the pressure protrusion 3201 slides off the inclined end, the knocking rod 318 falls rapidly due to gravity, thereby impacting the contact line 100, so that the contact line 100 can be intermittently impacted and vibrated, and the snow and ice on the contact line 100 can be better removed through the combination of the snow sweeping and ice shoveling actions.

[0036] The above is only a preferred embodiment of the present application, and is not used to limit the present application, any modification, equivalent replacement and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
