Description

Technical Field

[0001] The invention relates to the technical field of deicing and snow removal, and in particular to an automatic deicing device for bridge cables and a deicing method thereof. Background Art

[0002] The cable-stayed bridge is a structural system composed of pressure-bearing towers, tensioned cables and bending beams. The cables replace the piers, which has the advantages of reducing the bending moment of the beam, reducing the building height and weight, and saving materials. The cables of the cable-stayed bridge adopt the structure of parallel steel wires with a black low-density polyethylene PE protective layer. In the rainy and snowy weather in winter, the air humidity on the river surface is high, and the surface of the cables will freeze and be covered with icicles, which will bring great safety hazards to pedestrians and cars.

[0003] The existing patent CN110820604B discloses a creeping deicing and snow removal device, which includes a deicing device, a spraying device, and a driving assembly. The deicing device is designed with a rotary cutter and a rotating tooth. The ice on the cable of the cable-stayed bridge is broken by the rotation of the rotary cutter and the rotating tooth. The large ice bodies such as ice cones are crushed by the rotary cutter, and the ice layer surrounding the surface of the cable is broken by the rotating tooth, so as to achieve the effect of deicing and snow removal. The whole device is driven by the driving assembly to move upward along the cable, and when it reaches the top of the cable, it slides down under the control device. However, the device as a whole is a cylindrical device that fits on the cable, has weak adaptability to cables of different sizes, and the installation of the device is relatively complicated. Summary of the invention

[0004] The object of the present invention is to provide an automatic deicing device for bridge cables and a deicing method thereof which are simple to install, highly adaptable and have good deicing effect.

[0005] The technical solution adopted by the present invention is: an automatic de-icing device for bridge cables, including a support, a running wheel group and a de-icing mechanism, characterized in that: the support includes an upper support and a lower support, and at least two groups of upper running wheels and lower running wheels are respectively installed on the upper support and the lower support, the upper running wheels and the lower running wheels are relatively arranged to form a pair of running wheel groups, the two are connected by a telescopic member, and a de-icing mechanism is provided at the front end of the support, and the de-icing mechanism includes an upper clamping de-icing member and a lower clamping de-icing member that can be opened and closed around the cable, the upper clamping de-icing member and the lower clamping de-icing member are connected to the upper support and the lower support or the two ends of the telescopic member or the upper running wheel and the lower running wheel through a transmission mechanism, and when the telescopic member contracts, it drives the upper and lower running wheels to press the cable, and drives the upper and lower clamping de-icing members to clamp the cable through the transmission mechanism.

[0006] According to the above technical solution, the axles of the upper running wheel and the lower running wheel are respectively connected to the corresponding upper support and lower support through bearing seats, and at least one end of the telescopic member is hinged to the bearing seat, so that the upper and lower supports form an open and close structure.

[0007] According to the above technical solution, the running wheel set is driven by a driving mechanism.

[0008] According to the above technical solution, a displacement sensor capable of displaying the degree to which the cable is compressed by the running wheel set is installed on the telescopic member.

[0009] According to the above technical solution, protrusions for increasing friction are evenly distributed on the surface of the running wheel set.

[0010] According to the above technical solution, a power system for providing power to the running wheel set, the telescopic member and the de-icing mechanism is fixed on the support.

[0011] According to the above technical solution, the support is connected to a control system capable of remotely controlling the entire device.

[0012] According to the above technical scheme, the upper and lower clamping deicing parts include two semicircular deicing scrapers that can be tightly attached to the surface of the cable when closed and a vibrating ice-breaking part. The vibrating ice-breaking part is evenly arranged along the circumference of the semicircular deicing scrapers. The vibrating ice-breaking part includes a vibrating push rod motor and an ice-breaking end arranged at the front end of the vibrating push rod motor.

[0013] According to the above technical solution, the transmission mechanism includes two connecting rods arranged crosswise and hinged at the intersection, the two ends of the connecting rods are respectively hinged to the clamping deicing part and the connecting plate, and the connecting plate is tightly connected to the bearing seat of the running wheel group.

[0014] According to the above technical solution, the deicing steps of the deicing method of the automatic deicing device for bridge cables described in the present invention are as follows:

[0015] Step 1: When installing and arranging the device, first loosen the pins between the telescopic parts and the upper and lower running wheels, insert the upper and lower running wheels into the bridge cables, then install the front-end deicing mechanism, respectively put the upper and lower clamping deicing parts around the cables, connect the two cross connecting rods through the pins, and finally fasten the connecting plate to the bearing seat;

[0016] Step 2: After the device is installed, start the control system and operate the device remotely. The telescopic parts are contracted to make the upper and lower running wheels press the cable tightly. At the same time, the upper and lower clamping deicing parts are driven by the transmission mechanism to clamp the cable tightly. The vibrating deicing parts are adjusted to a suitable position. Then the vibrating push rod motor is started to break the ice layer on the surface of the cable through the high-frequency reciprocating motion of the ice-breaking end. The running wheels are controlled to move forward. The deicing scraper shovels away the broken ice on the way to achieve a deicing effect from bottom to top.

[0017] Step 3: After de-icing is completed, the remote-controlled running wheel rotates in the opposite direction, and the device gradually retreats along the cable and returns to the ground.

[0018] The beneficial effects achieved by the present invention are:

[0019] 1. The support, running wheel set and deicing mechanism of the device of the present invention are divided into upper and lower parts. During installation, it is only necessary to loosen the connecting parts between the upper and lower structures, put the whole device into the cable, and then connect them. The installation of the whole deicing device is very convenient.

[0020] 2. The deicing mechanism and the running wheel group of the device are connected through a transmission mechanism, which can not only drive the upper and lower running wheels to press the cable when the telescopic part contracts, but also drive the upper and lower clamping deicing parts to clamp the cable through the transmission mechanism. This structural form has stronger adaptability to the cable. According to the changes in the size of the cable of different bridges, deicing operations can be carried out by simply replacing the running wheel group and the deicing scraper.

[0021] 3. This device uses a high-frequency vibration push rod motor to drive the ice-breaking end to vibrate and break the ice, and then uses a semicircular de-icing scraper to shovel away the broken ice, which has a better de-icing effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0032] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, or are directions or positional relationships in which the product of the application is usually placed when in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0033] like Figure 1 , 2As shown, the present invention provides an automatic deicing device for bridge cables, comprising a support 1, a running wheel group 2 and a deicing mechanism 3, wherein the support 1 comprises an upper support 101 and a lower support 102, wherein at least two groups of upper running wheels 201 and lower running wheels 202 are respectively mounted on the upper support 101 and the lower support 102, wherein the upper running wheels 201 and the lower running wheels 202 are arranged opposite to each other to form a pair of running wheel groups 2, wherein the upper and lower running wheels (201, 202) are connected by a telescopic member 5, and a deicing mechanism 3 is provided at the front end of the support 1. 3, the deicing mechanism 3 comprises an upper clamping deicing member 310 and a lower clamping deicing member 320 which can be opened and closed around the cable 8, the upper clamping deicing member 310 and the lower clamping deicing member 320 are connected to the upper support 101 and the lower support 102 or the two ends of the telescopic member 5 or the upper running wheel 201 and the lower running wheel 202 through the transmission mechanism 4, and the telescopic member 5 drives the upper and lower running wheels (201, 202) to press the cable 8 when it contracts, and drives the upper and lower clamping deicing members (310, 320) to clamp the cable 8 through the transmission mechanism 4. The support 1, the running wheel group 2 and the deicing mechanism 3 of the device of the present invention are divided into upper and lower parts. When installing, it is only necessary to loosen the connecting piece between the upper and lower structures, put the whole device into the cable 8, and then connect it. The installation of the whole deicing device is very convenient. The deicing mechanism 3 and the running wheel group 2 of the device are connected through the transmission mechanism 4, which can not only realize that when the telescopic member 5 is retracted, the upper and lower running wheels (201, 202) can be driven to press the cable 8. The transmission mechanism 4 can also drive the upper and lower clamping deicing members (310, 320) to clamp the cable 8. This structural form has stronger adaptability to the cable 8. According to the change of the size of the cable 8 of different bridges, it is only necessary to replace the running wheel group 2 and the deicing scraper 303 to perform deicing operations.

[0034] In this embodiment, Figure 3 The upper support 101 and the lower support 102 are arranged relatively parallel, and there are two groups of running wheel groups 2 installed thereon. A bearing seat 203 is arranged on the wheel axle of the running wheel group 2, and the bearing seat 203 is fixed to the upper support 101 and the lower support 102 by bolts. The upper running wheel 201 and the lower running wheel 202 are connected to the telescopic member 5 through a pin 204 to form an articulated connection. After the pin 204 is released, one side of the upper running wheel 201 and the lower running wheel 202 is opened, thereby realizing the detachable installation of the running wheel group 2. The upper and lower running wheels (201, 202) are made of rubber, and small round nails are evenly distributed on their surfaces for increasing friction.

[0035] In this embodiment, the telescopic member 5 is a hydraulic cylinder, on which is installed a displacement sensor 206 capable of displaying the degree of compression of the running wheel group 2. The displacement sensor 206 is respectively connected to both ends of the hydraulic cylinder. When the hydraulic cylinder contracts, the displacement sensor 206 can display the displacement distance at both ends, so as to facilitate the regulation of the degree of compression of the running wheel group 2 on the cable 8, thereby preventing the device from slipping due to insufficient contraction of the hydraulic cylinder, and preventing the device from being damaged due to excessive contraction of the hydraulic cylinder.

[0036] In this embodiment, Figure 4 As shown, the upper and lower clamping deicing parts (310, 320) include two semicircular deicing scrapers 303. The two deicing scrapers 303 can be tightly attached to the surface of the cable 8 when closed, and can scrape away broken ice when moving along the surface of the cable 8. The two deicing scrapers 303 are arranged opposite to each other and are respectively fixed on the upper bracket 304 and the lower bracket 305. The brackets are welded from long strip angle steels. The deicing scrapers 303 are square plates with arc grooves on their edges, and the processing technology is simple.

[0037] In this embodiment, the upper and lower clamping deicing parts (310, 320) also include a vibrating ice-breaking part, and six of the vibrating ice-breaking parts are arranged evenly along the circumference of the deicing scraper 303, specifically, three are arranged on the upper bracket 304, and three are arranged on the lower bracket 305, which are respectively fixed to the corresponding brackets by bolts. The vibrating ice-breaking part includes a vibrating push rod motor 301 and an ice-breaking end 302 arranged at the front end of the vibrating push rod motor 301. The vibrating push rod motor 301 can convert the rotational power generated by the motor into high-frequency vibration of the push rod during operation, driving the ice-breaking end 302 to break the ice layer on the surface of the cable 8. Specifically, the ice-breaking end 302 is a quasi-circular arc segment, on which protrusions that are conducive to ice breaking are distributed.

[0038] In this embodiment, Figure 5 As shown, the transmission mechanism 4 includes two cross-arranged connecting rods 401, which are connected by a pin 204 in the middle and can rotate around the connection point as the axis. One end of the connecting rod 401 is hinged to the bracket on which the upper and lower de-icing mechanisms 3 are installed through the pin 204, and the other end is hinged to the connecting plate 402 through the pin 204. The connecting plate 402 is fastened to the bearing seat 203 by bolts.

[0039] In this embodiment, a power system 6 for providing power to the running wheel set 2, the telescopic member 5 and the deicing mechanism 3 is fixed on the upper support 101. The power system 6 uses a lithium battery to provide power to the hydraulic pump station, drives the hydraulic cylinder and the hydraulic motor 205 installed on the bearing seat 203, realizes the movement of the device, and drives the deicing mechanism 3 to operate to achieve ice breaking and deicing effects. A control system 7 is fixed on the lower support 102, which can remotely control the rotation of the running wheel set 2 and the contraction degree of the hydraulic cylinder, and then control the deicing mechanism 3 to ensure the safety and reliability of the entire deicing operation.

[0040] This embodiment also provides a deicing method using the above-mentioned deicing device, and the specific steps are as follows:

[0041] Step 1: Before performing the automatic deicing operation, first manually de-ice the bottom of the bridge cable 8 to ensure that the installation environment of the de-icing equipment is clean and to prevent the bottom ice layer from affecting the normal operation of the device.

[0042] Step 2: If Figure 6 As shown, when installing the device, first loosen the pin 204 between the telescopic member 5 and the bearing seat 203 to open the running wheel group 2, then insert the upper and lower running wheels (201, 202) into the bridge cable 8, install the pin 204, and complete the installation of the running wheel group 2.

[0043] Step 3: If Figure 7 As shown, the upper and lower clamping deicing parts (310, 320) are respectively wrapped around the cable 8, and the upper pin 204 is installed between the two cross-connected connecting rods 401, so that the deicing mechanism 3 is sleeved on the cable 8, and finally the connecting plate 402 at the end of the connecting rod 401 is fixed to the bearing seat 203 with bolts, and the running wheel group 2 and the front end deicing mechanism 3 are connected into a whole, completing the installation of the entire device.

[0044] Step 3: If Figure 8 As shown, after the device is installed, the control system 7 is started, and the remote control device is operated. The telescopic member 5 contracts to drive the upper and lower running wheels (201, 202) to press the cable 8, and then the upper and lower clamping deicing members (310, 320) are driven through the connecting rod 401, so that the upper and lower clamping deicing members (310, 320) clamp the cable 8, and the vibrating ice-breaking member is adjusted to a suitable position. After the vibration push rod motor 301 is started, it drives the ice-breaking end 302 to reciprocate at high frequency to break the ice layer on the surface of the cable 8, and the hydraulic motor 205 on the bearing seat 203 rotates to push the running wheel group 2 forward. On the way, the deicing scraper 303 close to the surface of the cable 8 shovels away the broken ice, so as to achieve a deicing effect from bottom to top;

[0045] Step 4: When the device moves to the uppermost end of the cable 8 and completes the de-icing task, the control system 7 remotely controls the running wheel set 2 to rotate in the opposite direction, and the device gradually retreats along the cable 8 and returns to the ground.

[0046] The embodiments described above are part of the embodiments of the present invention, rather than all of the embodiments. The detailed description of the embodiments of the present invention is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention.
