Description

Technical Field

[0001] The utility model relates to the field of car dumper, in particular to a car leaning mechanism of a dumper for unloading open-top containers. Background Technique

[0002] A dumper is a large mechanical device used to unload bulk materials from railway gondolas. It is a loading and unloading machine that can turn or tilt a rail vehicle to unload materials. It is widely applicable to ports with large transportation volumes and industrial sectors such as metallurgy, coal, and thermal power.

[0003] The car leaning mechanism of a dumper is a mechanical mechanism that fixes the train car body during the turning or tilting process of the dumper. Currently, due to the new addition of open-top containers in the railway system, compared with the original railway gondolas, the width of this container has been reduced a lot, about 2550 mm, and the width of the railway flat car carrying the container is 3157 - 3180 mm. Due to the different widths of the flat car and the container, the original car leaning mechanism of the dumper cannot meet the requirements of unloading both the flat car and the open-top container at the same time. That is, the size of the car leaning plate is fixed and cannot act independently on flat cars and containers of different sizes. Therefore, different dumpers are used to unload the flat car and the container respectively, resulting in high unloading costs.

[0034] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0035] As Figures 1 to 3 shown, a car-abutting mechanism of a car dumper for dumping open-top containers disclosed in this embodiment includes an upper abutting plate 1 and a lower abutting plate 2. The lower abutting plate 2 is located below the upper abutting plate 1, and the car-abutting surface area of the upper abutting plate 1 is larger than that of the lower abutting plate 2, so that when dumping an open-top container, the upper abutting plate 1 can act on the side of the container, and the lower abutting plate 2 can act on the side of the flat car to realize the function of respectively abutting against the car; when dumping a railway gondola car, the upper abutting plate 1 and the lower abutting plate 2 act on the side of the gondola car simultaneously to realize the function of abutting against the car.

[0036] As Figure 1 and 2 shown, upper abutting plate legs 3 are provided at both ends of the upper abutting plate 1. The upper ends of the upper abutting plate legs 3 are rotatably connected to the upper abutting plate 1, and the lower ends are rotatably connected to the upper leg seats 301. The upper leg seats 301 are fixed on the car dumper 11. A upper abutting drive assembly 5 is provided on the back surface of the upper abutting plate 1. The front end of the upper abutting drive assembly 5 is connected to the upper abutting plate 1, and the rear end is connected to the rear beam 7 of the car dumper. The rear beam 7 of the car dumper is fixed on the car dumper 11.

[0037] The upper car-resting drive assembly 5 specifically includes a guiding device 501 and an upper car-resting plate oil cylinder 502. The guiding device 501 is located above the upper car-resting plate oil cylinder 502. The front ends of both the guiding device 501 and the upper car-resting plate oil cylinder 502 are rotatably connected to the upper car-resting plate 1, and the rear ends of both the guiding device 501 and the upper car-resting plate oil cylinder 502 are rotatably connected to the rear beam 7 of the dumper. In this embodiment, two groups of guiding devices 501 are provided behind the upper car-resting plate 1. Each group of guiding devices includes two horizontally arranged guiding telescopic rods, and the guiding device is relied on to ensure that the upper car-resting plate 1 does not deviate significantly left and right during the movement process. Meanwhile, two upper car-resting plate oil cylinders 502 are provided behind the upper car-resting plate 1, and the two upper car-resting plate oil cylinders 502 are located at both ends of the lower part of the upper car-resting plate 1.

[0038] As Figure 1 and 2 shown, lower car-resting plate legs 4 are provided at both ends of the lower car-resting plate 2. The lower car-resting plate legs 4 include two leg rods 401. The two leg rods 401 are arranged in parallel. The upper ends of the two leg rods 401 are rotatably connected to the lower car-resting plate 2, and the lower ends of the two leg rods 401 are rotatably connected to the lower leg seat 402. The lower leg seat 402 is fixed on the dumper 11. Specifically, the top of one leg rod 401 is hinged to the bottom surface of the lower car-resting plate 2, the top of one leg rod 401 is hinged to the side surface of the lower car-resting plate 2, and the bottoms of the two leg rods 401 are both hinged to the lower leg seat 402. The lower leg seat 402, the two leg rods 401, and the lower car-resting plate 2 form a parallel four-bar linkage structure with four hinge points, ensuring that the lower car-resting plate 2 always remains horizontal during the movement process. A lower car-resting drive assembly 6 is provided on the back surface of the lower car-resting plate 2. The front end of the lower car-resting drive assembly 6 is connected to the lower car-resting plate 2, and the rear end is connected to the rear beam 7 of the dumper.

[0039] The lower car-resting drive assembly 6 specifically includes lower car-resting plate oil cylinders 601. The number of lower car-resting plate oil cylinders 601 is two. The front ends of the lower car-resting plate oil cylinders 601 are rotatably connected to the lower car-resting plate 2, and the rear ends of the lower car-resting plate oil cylinders 601 are rotatably connected to the rear beam 7 of the dumper. The two lower car-resting plate oil cylinders 601 are respectively arranged near both ends of the lower car-resting plate 2; the car-resting and releasing actions of the car-resting mechanism are completed by the extension and retraction of the car-resting oil cylinders. When the piston rod of the oil cylinder extends, the car-resting mechanism performs the car-resting action, and when the piston rod of the oil cylinder retracts, the car-resting mechanism performs the releasing action.

[0040] As Figure 3 and 6 shown, a detection hole 101 is provided in the middle of the upper car-resting plate 1, and an upper car-resting plate car-resting detection device 8 is arranged in the detection hole 101. The upper car-resting plate car-resting detection device 8 is used to detect and feedback the car-resting signal of the upper car-resting plate 1.

[0041] Specifically, the upper backboard car-relying detection device 8 includes a second bracket 801, a second sensor 802, a second elastic member 803, and a contact strip 804; the vertical portion of the second bracket 801 is rotatably connected to the support 805, the support 805 is fixed on the upper backboard 1, and an elastic member 803 for resetting the second bracket 801 is provided at the rotation connection position between the support 805 and the second bracket 801. The horizontal portion of the second bracket 801 passes through the detection hole 101, and the front end of the horizontal portion of the second bracket 801 extends to the outside of the detection hole 101 and is connected to the contact strip 804; a detection plate 806 is provided at the rear end of the horizontal portion of the second bracket 801, and the detection plate 806 cooperates with the second sensor 802. The second sensor 802 is fixed on the upper backboard 1.

[0042] Before the upper backboard 1 moves to the side of the container or the flat car under the drive of the upper backboard oil cylinder 502, the contact strip 804 protruding from the side of the upper backboard 1 is first subjected to a squeezing force. The contact strip 804 drives the second bracket 801 to rotate backward, and the end of the detection plate 806 triggers the second sensor 802. The signal is fed back to the controller through the second sensor 802, and the controller controls the extension length of the upper backboard oil cylinder 502 by controlling the oil circuit system.

[0043] In this embodiment, the second sensor 802 may specifically be a Turck proximity switch. The number of the second brackets 801 is two and they are arranged at intervals. The detection plate 806 is fixed to one of the second brackets 801. The contact strip 804 is made of rubber material.

[0044] As Figure 7 shown, in this embodiment, the second elastic member 803 is specifically an elastic rubber block; a hole position for fixing the second elastic member 803 is provided on the support 805, and the end of the second elastic member 803 is fixed to the second bracket 801. The second bracket 801 will drive the elastic rubber block to deform during the torsion process, and the deformation of the elastic rubber block is used for resetting the second bracket 801.

[0045] As Figure 4 、 8 and Figure 9 show that the rear end of the lower backboard oil cylinder 601 is connected to the rear beam 7 of the dumper through the lower backboard car-relying detection device 9; the lower backboard car-relying detection device 9 is used to detect and feedback the car-relying signal of the lower backboard 2.

[0046] Specifically, the lower backboard car-relying detection device 9 includes a first bracket 901, a first sensor 902, a first elastic member 903, and a contact block 904. The first bracket 901 is in a triangular structure and is fixed on the rear beam 7 of the dumper. The top of the contact block 904 is movably connected to the first bracket 901 through a connecting rod group 905. The front part of the contact block 904 is rotatably connected to the lower backboard oil cylinder 601. The rear part of the contact block 904 is fixed with a first elastic member 903, and one end of the first elastic member 903 away from the contact block 904 abuts against the first sensor 902, and the first sensor 902 is fixed on the first bracket 901.

[0047] At present, the lower fender 2 makes a fender action driven by the lower fender oil cylinder 601. After acting on the side of the gondola car or the flat car, under its limit, the lower fender oil cylinder 601 receives a reverse acting force, and the contact block 904 moves backward to drive the first elastic member 903 to deform the first sensor 902. The signal fed back by the first sensor 902 is sent to the controller, and the controller controls the oil circuit system to control the extension length of the lower fender oil cylinder 601. Among them, the first sensor 902 can specifically be a Turck proximity switch.

[0048] Among them, the purpose of hinging the contact block 904 and the first bracket 901 through the link group 905 is to facilitate the more flexible movement of the contact block 904. As Figure 9 shown, the link group 905 includes a first link 905-1, a second link 905-2 and a third link 905-3. The first link 905-1 and the second link 905-2 are arranged side by side. The upper ends of the first link 905-1 and the second link 905-2 are both rotatably connected to the first bracket 901, and the lower ends of the first link 905-1 and the second link 905-2 are both rotatably connected to the contact block 904. The first link 905-1, the second link 905-2, the first bracket 901 and the contact block 904 form a parallelogram four-bar structure.

[0049] The third link 905-3 is used to improve the stability of the parallelogram four-bar structure. Specifically, the third link 905-3 is arranged on both sides of the contact block 904. A kidney-shaped guide slide hole 905-4 is provided at the lower end of the third link 905-3, and the kidney-shaped guide slide hole 905-4 is slidably connected to the rotating shaft at the lower end of the second link 905-2; the upper end of the third link 905-3 is connected to the rotating shaft at the upper end of the first link 905-1.

[0050] As Figure 10 shown, in this embodiment, a vibration device 10 is further provided on the upper fender 1. The vibration device 10 can be composed of a vibration motor and a controller. When the upper fender 1 contacts the gondola car compartment, the controller controls the vibration motor to start to vibrate the compartment to assist in coal removal.

[0051] In this embodiment, buffer rubber plates are covered on the fronts of the upper fender 1 and the lower fender 2. The buffer rubber plates are installed on the fender body to prevent the metal plate of the fender body from directly contacting the carriage.

[0052] As Figure 11 shown, the use process of the present utility model is as follows:

[0053] First, the fender action and the release action of the fender mechanism are completed by the extension and retraction of the fender oil cylinder. When the piston rod of the oil cylinder extends, the fender mechanism makes a fender action, and when the piston rod of the oil cylinder retracts, the fender mechanism makes a release action.

[0054] By dividing the car-side plate into two parts, namely the upper car-side plate 1 and the lower car-side plate 2, when tipping a railway gondola car, the upper car-side plate 1 and the lower car-side plate 2 act on the side of the gondola car simultaneously to achieve the car-side function; when tipping an open-top container car, the upper car-side plate 1 acts on the side of the container, and the lower car-side plate 2 acts on the side of the flat car to achieve the separate car-side function; the car-side and release actions of the car-side mechanism are completed by the extension and retraction of the upper car-side drive assembly 5 and the lower car-side drive assembly 6, and the car-side in-place detection is carried out by the upper car-side plate car-side detection device 8 and the lower car-side plate car-side detection device 9. The two parts of the upper car-side plate 1 and the lower car-side plate 2 act independently without interference, and can not only complete the tipping of the open-top container car, but also meet the tipping of various types of railway gondola cars.

[0055] The embodiments described above are only descriptions of the preferred embodiments of the present invention, and do not limit the scope of the present invention.
