Description

Technical Field

[0001] This utility model relates to the technical field of coal transportation devices in thermal power plants, and in particular to a coal car top coal cleaning device. Background Technology

[0002] Currently, many thermal power plants in China use trains to transport coal, which is convenient and efficient. However, after the coal is unloaded by tippers, some residual coal often remains on the surface and top of the wagons. If this residual coal is not removed in time, it will not only lead to cost losses but also pollute the environment and violate the relevant regulations of the railway department on wagon management.

[0003] The existing methods for cleaning up residual coal on car sides have the following problems:

[0004] 1. The work of cleaning up the remaining material in the carriages mainly relies on manual operation. Due to the height of the train carriages, it is still inconvenient for staff to clean up the remaining coal on the sides of the carriages when they are standing inside.

[0005] 2. There are usually two models of the car body, C70 and C80. The height of C80 is higher than that of C70. The existing car body residual coal cleaning device is not suitable for use and is inconvenient to use and switch. Utility Model Content

[0006] This utility model provides a coal car sidewall top residual coal cleaning device, which aims to solve the problems mentioned above, such as the inconvenience and low efficiency of manual residual coal cleaning and the lack of applicability of the existing devices.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0008] A coal car side top residual coal cleaning device includes a fixed support. The main body of the fixed support is a vertically arranged tubular structure. A support rod is concentrically and coaxially embedded in the tube. The support rod rotates around the axis in the fixed support. During the rotation, the support rod forms a limiting engagement with the fixed support at two positions through a limiting part.

[0009] The top of the support rod is fixed with a first cleaning frame and a second cleaning frame, and the first cleaning frame and the second cleaning frame correspond one-to-one with two limit positions. Both the first cleaning frame and the second cleaning frame are detachably equipped with rubber scrapers.

[0010] Preferably, when the support rod and the fixed support are fixed in the first limiting position by the limiting component, the first sweeping frame is located directly above the side of the vehicle, and the second sweeping frame is located away from the side of the vehicle, and the rubber scraper of the first sweeping frame cooperates with the side of the vehicle to form a scraper.

[0011] When the support rod and the fixed support are fixed in the second limiting position by the limiting component, the second sweeper is located directly above the side of the vehicle, and the first sweeper is located away from the side of the vehicle. The rubber scraper of the second sweeper cooperates with the side of the vehicle to form a scraper.

[0012] More preferably, the residual coal cleaning devices are used in pairs, with the two residual coal cleaning devices arranged symmetrically about the track.

[0013] More preferably, a fixing plate is welded to the bottom of the fixing support, the fixing support is perpendicular to the fixing plate, and the fixing plate is detachably fixed to the side of the track by fasteners.

[0014] More preferably, the first cleaning frame and the second cleaning frame have the same structure.

[0015] Furthermore, the first cleaning frame includes a hollow vertical tube, which is coaxially sleeved on the outer side of the top of the support rod and fixedly engaged with the support rod. A horizontal tube arranged radially along the support rod is fixed to the top of the outer side of the vertical tube. The horizontal tube is perpendicular to the vertical tube. An inclined tube is fixed between the end of the horizontal tube away from the vertical tube and the outer side of the bottom of the vertical tube to form an inclined support. The horizontal tube, the vertical tube and the inclined tube cooperate to form a right triangle.

[0016] Furthermore, the horizontal pipe is provided with several fastening bolts at equal intervals, and the fixing part of the rubber scraper is fixedly installed to the horizontal pipe by the fastening bolts, with the blade head of the rubber scraper pointing vertically downward.

[0017] More preferably, the limiting component includes a steering handle fixed to the outer wall of the support rod. The steering handle is arranged radially. The port of the fixed support is provided with a first limiting groove that opens radially at the first limiting position and a second limiting groove that opens radially at the second limiting position. When the steering handle is embedded and engaged in the first limiting groove or the second limiting groove, the support rod and the fixed support form a limiting fixation.

[0018] More preferably, the fixed support, support rod, limiting component, first cleaning frame and second cleaning frame are all made of hard alloy material, and the support rod is a solid rod.

[0019] Furthermore, the length of the fixed support is not less than one-third of the length of the support rod.

[0020] The beneficial effects of this utility model are:

[0021] 1. The device is easy to install and disassemble. During installation, simply insert the support rod into the fixed support to complete the fixed installation and make the support rod stand upright. When the train passes slowly, the rubber scraper installed on the top of the support rod scrapes the residual coal on the top of the car side to clean it. No manual cleaning is required, which improves cleaning efficiency and ensures cleaning effect.

[0022] 2. The position of the limiting component can be adjusted by rotating the support rod, thereby limiting and fixing it at different designated positions. When limited to a designated position, the sweeping frame corresponding to that position matches the side of the vehicle, thus facilitating the adjustment of sweeping frames of different heights to meet the cleaning needs of side of vehicles of different heights, improving the applicability and ease of use of the device.

[0026] The embodiments will be further described below with reference to the accompanying drawings.

[0027] like Figure 1 and Figure 2 As shown in the preferred embodiment 1, a coal car side top residual coal cleaning device includes a fixed support 1. The main body of the fixed support 1 is a vertically arranged tubular structure. A support rod 3 is embedded in the tube in a concentric and coaxial manner. The support rod 3 rotates around the axis in the fixed support 1. During the rotation, the support rod 3 forms a limiting cooperation with the fixed support 1 in two positions through the limiting part.

[0028] The top of the support rod 3 is fixed with a first cleaning frame 4 and a second cleaning frame 5 respectively, and the first cleaning frame 4 and the second cleaning frame 5 correspond one-to-one with the two limit positions. Both the first cleaning frame 4 and the second cleaning frame 5 are detachably equipped with rubber scrapers 6.

[0029] When the support rod 3 and the fixed support 1 are fixed in the first limiting position by the limiting component, the first sweeping frame 4 is located directly above the side of the vehicle, and the second sweeping frame 5 is located away from the side of the vehicle. The rubber scraper 6 of the first sweeping frame 4 forms a scraper cooperation with the side of the vehicle.

[0030] When the support rod 3 and the fixed support 1 are fixed in the second limiting position by the limiting component, the second sweeping frame 5 is located directly above the side of the vehicle, and the first sweeping frame 4 is located away from the side of the vehicle. The rubber scraper 6 of the second sweeping frame 5 cooperates with the side of the vehicle to form a scraper.

[0031] Taking the first cleaning rack 4 at the bottom and the second cleaning rack 5 at the top as an example, the first cleaning rack 4 is for cleaning the side of the C70 carriage, and the second cleaning rack 5 is for cleaning the side of the C80 carriage.

[0032] When the C70 car arrives, the worker rotates the support rod 3 and fixes it in the first position through the limiting component. The first cleaning frame 4 is perpendicular to the direction of train operation, and the second cleaning frame 5 is parallel to the train car and does not contact the side of the car. With the ground as a reference, the first cleaning frame 4 is stationary, while the train moves. Using the relative motion, the rubber scraper 6 scrapes off the remaining coal on the side of the car.

[0033] When the C80 car arrives, the worker rotates the support rod 3 and fixes it in the second position through the limiting component. At this time, the second cleaning frame 5 is perpendicular to the direction of train operation, and the first cleaning frame 4 is parallel to the train car and does not contact the side of the car. With the ground as a reference, the second cleaning frame 5 is stationary, while the train moves. Using the relative motion, the rubber scraper 6 scrapes off the remaining coal on the side of the car.

[0034] In a preferred embodiment 2, the residual coal cleaning devices are used in pairs, with the two devices arranged symmetrically about the track. They simultaneously clean the sides of the car.

[0035] In a preferred embodiment 3, a fixing plate is welded to the bottom of the fixed support 1, the fixed support 1 is perpendicular to the fixing plate, and the fixing plate is detachably fixed to the side of the track by fasteners. This ensures the convenience and stability of installing and disassembling the fixed support 1.

[0036] As a preferred embodiment 4, the first cleaning frame 4 and the second cleaning frame 5 have the same structure.

[0037] The first cleaning frame 4 includes a hollow vertical tube 7. The vertical tube 7 is coaxially sleeved on the outer side of the top of the support rod 3 and fixedly engaged with the support rod 3. A horizontal tube 8 is fixed on the top of the outer side of the vertical tube 7 and arranged radially along the support rod 3. The horizontal tube 8 is perpendicular to the vertical tube 7. An inclined tube 9 is fixed between the end of the horizontal tube 8 away from the vertical tube 7 and the outer side of the bottom of the vertical tube 7 to form an inclined support. The horizontal tube 8, the vertical tube 7 and the inclined tube 9 cooperate to form a right triangle.

[0038] The horizontal tube 8, the vertical tube 7, and the inclined tube 9 are welded together to form a right triangle. When the vertical tube 7 is mounted on the support rod 3 and moves to the set position, it is fixed by welding to ensure the stability of the fixation.

[0039] In a more preferred embodiment 5, a plurality of fastening bolts are provided at equal intervals on the horizontal pipe 8, and the fixing part of the rubber scraper 6 is fixedly installed to the horizontal pipe 8 by the fastening bolts, with the blade head of the rubber scraper 6 pointing vertically downward. This facilitates the replacement and disassembly of the rubber scraper 6, and ensures that the rubber scraper 6 and the corresponding cleaning frame are on the same plane, making it easy to control the position of the rubber scraper 6.

[0040] As a preferred embodiment 6, the limiting component includes a steering handle 2 fixed to the outer wall of the support rod 3. The steering handle 2 is arranged radially. The pipe opening of the fixed support 1 is provided with a first limiting groove 10 with a radial opening at the first limiting position and a second limiting groove 11 with a radial opening at the second limiting position. When the steering handle 2 is embedded and engaged in the first limiting groove 10 or the second limiting groove 11, the support rod 3 and the fixed support 1 form a limiting fixation.

[0041] For easy adjustment, when the support rod 3 is inserted into the fixed support 1, the support rod 3 can stand stably upright due to gravity and the limitation of the fixed support 1. The steering handle 2 cooperates with the limiting groove to form a limit, so that when the device needs to be adjusted, you only need to lift the steering handle 2 to lift the support rod 3, and then rotate the support rod 3 until the steering handle 2 rotates to the corresponding limiting groove. After the steering handle 2 is put into the corresponding limiting groove, the limit is locked by gravity, and the limiting and fixing are completed. It is convenient to adjust and can ensure the function of limiting and fixing.

[0042] In a preferred embodiment 7, the included angle between the first limiting groove 10 and the second limiting groove 11 at their centers is the same as the included angle between the first sweeping frame 4 and the second sweeping frame 5 at their centers. This ensures that when the rotating handle 2 rotates from the first limiting groove 10 to the second limiting groove 11, the second sweeping frame 5 rotates by the same angle to the first sweeping frame 4, facilitating alignment adjustment. An angle of not less than 90° is sufficient to ensure that each component contacts the other without interfering with the others.

[0043] In a more preferred embodiment 8, the included angle between the first limiting groove 10 and the second limiting groove 11 at their centers is 90°, and the included angle between the first cleaning frame 4 and the second cleaning frame 5 at their centers is also 90°. This facilitates alignment.

[0044] When the handle 2 is rotated at the first limit groove 10, the first cleaning frame 4 is perpendicular to the direction of train travel, while the second cleaning frame 5 is parallel to the train, so that the first cleaning frame 4 scrapes the side of the train while the second cleaning frame 5 does not come into contact with the train.

[0045] When the handle 2 is rotated to the second limit groove 11, the second sweeping frame 5 is perpendicular to the train's forward direction, while the first sweeping frame 4 is parallel to the train. This allows the second sweeping frame 5 to clean the sides of the train while the first sweeping frame 4 does not come into contact with the train. This ensures that the two frames are independent of each other and facilitates adjustment and alignment.

[0046] In a preferred embodiment 9, the fixed support 1, support rod 3, limiting component, first cleaning frame 4, and second cleaning frame 5 are all made of hard alloy material, and the support rod 3 is a solid rod. This ensures the rigidity and hardness of the structure, reduces deformation during use, and guarantees structural stability throughout its service life.

[0047] In a more preferred embodiment 10, the length of the fixed support 1 is not less than one-third of the length of the support rod 3. This ensures the stability of the support rod 3 after it is installed, preventing it from bending or falling out.

[0048] The working principle of this utility model:

[0049] Taking the first cleaning rack 4 at the bottom and the second cleaning rack 5 at the top as an example, the first cleaning rack 4 is for cleaning the side of the C70 carriage, and the second cleaning rack 5 is for cleaning the side of the C80 carriage.

[0050] When the C70 carriage comes at low speed, the worker uses the steering handle 2 to rotate the support rod 3 and lock it into the first limiting groove 10 of the fixed support 1. The first cleaning frame 4 is perpendicular to the direction of train operation, and the second cleaning frame 5 is parallel to the train carriage and does not contact the side of the carriage. With the ground as a reference, the first cleaning frame 4 is stationary while the train moves. Using the relative motion, the rubber scraper 6 scrapes off the remaining coal on the side of the carriage.

[0051] When the C80 carriage approaches at low speed, the worker uses the steering handle 2 to rotate the support rod 3 and lock it into the second limiting groove 11 of the fixed support 1. At this time, the second sweeping frame 5 is perpendicular to the direction of train operation, and the first sweeping frame 4 is parallel to the train carriage and does not contact the side of the carriage. With the ground as a reference, the second sweeping frame 5 is stationary while the train moves. Using the relative motion, the rubber scraper 6 scrapes off the remaining coal on the side of the carriage.
