Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of dumper, specifically to the technical field of a tipping plate for a dumper, and particularly to a dumper tipping plate device suitable for complete discharging. Background Art
[0002] The dumper system is a very specialized bulk material discharging system, which is used for discharging bulk materials loaded on trains. After the carriage enters the loading platform of the dumper, a pair of clamping mechanisms at the top clamp the top of the carriage, and the rotor mechanism rotates to tilt the loading platform and the carriage towards the tipping side, and then the materials in the carriage are discharged.
[0003] In the traditional technology, the tipping angle is rated at 165° and the maximum is 175°. This tipping method leaves a large amount of residual materials in the carriage. Then, large-angle dumpers emerged. By increasing the layout angle of the end ring track and the end ring tooth block, the tipping angle of the dumper exceeds 180° and reaches 205° - 220°. For standard railway open wagons, when tipping 180°, complete discharging can basically be achieved. However, for open-top container wagons, because there is a horizontal edge at the top, when tipping 180°, there are still residual materials on the horizontal edge. Therefore, it is necessary to further increase the tipping angle to 205° - 220°. Although the dumper can achieve large-angle tipping, there is also a situation where the traditional tipping plate is not matched. The traditional tipping plates all adopt the method of setting a vertically arranged main backing plate on the tipping side, or using the main backing plate and the auxiliary backing plate below the main backing plate to support the tipping side of the carriage. However, when the tipping angle of the dumper increases to more than 180°, the main backing plate and the auxiliary backing plate no longer support the carriage, and problems such as derailment of the carriage and deformation of the connecting pin shaft between the carriage and the bogie are likely to occur.
[0004] Therefore, a tipping plate device that can be adapted to a large-angle dumper is needed. Content of the Utility Model
[0005] According to the above technical problems, a dumper tipping plate device suitable for complete discharging is provided. The utility model mainly uses a vehicle bottom backing plate mechanism added on the non-tipping side to enable the vehicle bottom backing plate mechanism and the main backing plate to always clamp the carriage, preventing derailment of the vehicle and deformation of the connecting hinge shaft between the bogie and the carriage.
[0006] The technical means adopted by the utility model are as follows:
[0007] A dumper tipping plate device suitable for complete discharging includes a main backing plate arranged on the tipping side of the dumper and a vehicle bottom backing plate mechanism arranged on the non-tipping side of the dumper;
[0008] The underbody backing plate mechanism includes an underbody backing plate, and a plurality of flap units are arranged along the length direction of the underbody backing plate. The flap units are used to flip the underbody backing plate so that it closely abuts against the vehicle overturned by the car dumper.
[0009] Preferably, an auxiliary backing plate is arranged below the main backing plate, and the auxiliary backing plate faces the underbody backing plate in the state of closely abutting against the vehicle.
[0010] Preferably, the flap unit includes a hydraulic cylinder and a connecting rod group;
[0011] One end of the hydraulic cylinder is hinged to hinge point A fixed on the side wall of the loading platform, the other end of the hydraulic cylinder is hinged to hinge point B arranged on the underbody backing plate, one end of the connecting rod group is hinged to the underbody backing plate, and the other end is hinged to the side wall of the loading platform.
[0012] Preferably, the connecting rod group includes a first connecting rod and a second connecting rod. The first connecting rod and the second connecting rod are arranged in parallel. One ends of the first connecting rod and the second connecting rod are respectively hinged to hinge point C and hinge point D arranged on the underbody backing plate, and the other ends are respectively hinged to hinge point E and hinge point F fixed on the side wall of the loading platform. Hinge point C, hinge point D, hinge point E and hinge point F form the four vertices of a parallelogram. Hinge point B, hinge point C and hinge point D form the three vertices of an obtuse triangle, and hinge point B is an acute angle. Hinge point A, hinge point B, hinge point C, hinge point D, hinge point E and hinge point F do not coincide.
[0013] Preferably, an electromagnet is installed on the main backing plate.
[0014] Preferably, the underbody backing plate is a one-piece underbody backing plate.
[0015] Preferably, the underbody backing plate is a segmented underbody backing plate. Multiple segments of the underbody backing plate are evenly distributed along the length direction of the carriage, and at least one flap unit is connected to each segment of the underbody backing plate.
[0016] Preferably, when the underbody backing plate mechanism is in a non-closely abutting state, the underbody backing plate mechanism is lower than or in the plane of the loading platform.
[0017] Preferably, a maintenance platform is arranged beside the loading platform, and the maintenance platform is provided with an avoidance groove or an avoidance hole at the position of the underbody backing plate mechanism.
[0018] Preferably, when the vehicle overturned by the car dumper is an open-top railway wagon, the underbody backing plate closely abuts against the lower part of the carriage of the open-top railway wagon after flipping; when the vehicle overturned by the car dumper is an open-top container car, the underbody backing plate closely abuts against the side wall of the car body of the open-top container car after flipping.
[0019] Compared with the prior art, the utility model has the following advantages:
[0020] 1. A tipping plate device of a tippler applicable to complete discharging provided by the utility model realizes that when the vehicle is turned over by more than 180°, the auxiliary backing plate can play a supporting role by adding a vehicle bottom backing plate mechanism on the non-tipping side, avoiding the phenomenon that there is no structure to support the vehicle after exceeding 180° in the traditional tipping plate device.
[0021] 2. The reason why the vehicle bottom backing plate mechanism of the utility model is installed on the bearing platform instead of the front cross beam of the C-shaped end ring is that the non-tipping side end ring body and the front beam body are relatively weak. Supporting the backing plate and acting on the front beam body, the alternating load of its own weight and the vehicle leaning force are likely to cause deformation and cracking of the front beam body. If it is still desired to be installed on the front beam of the C-shaped end ring, it is necessary to change the bearing capacity of the front beam of the existing tippler and the strength of the non-tipping side end ring body to meet the use of the vehicle bottom backing plate, which will undoubtedly cause a large amount of transformation of the entire tippler and additionally increase more preparation costs. The utility model specifically installs the vehicle bottom backing plate mechanism on the bearing platform of the tippler. The bearing platform itself has good strength and can fully meet the use of the vehicle bottom backing plate without modifying the front beam. And through the flipping structural design, it will not affect the vehicle's entry and exit during the non-use process.
[0022] 3. When the utility model is aimed at a railway gondola car, the vehicle bottom backing plate is close to the lower part of the carriage of the railway gondola car after flipping, rather than the middle, because the steel strength of the lower part of the carriage itself is high enough and will not be damaged during the close process. If the middle is used for close contact, it is easy to cause deformation of the carriage. For an open-top container car, it is the same reason. The scheme of abutting against the side wall of the vehicle body with better strength is adopted instead of the scheme of closely contacting the container with insufficient strength. That is to say, the position where the vehicle bottom backing plate of the utility model holds is always the position with higher strength.
[0023] 4. With the design of the tipping plate structure, in the non-working state, it will not affect the normal entry and exit of the vehicle into and out of the tippler and will not occupy the side space of the tippler. If a translational backing plate structure is adopted, it will reduce the space in the C-shaped space of the tippler.
[0024] 5. The tipping plate unit adopts the structure of a connecting rod group. The first connecting rod, the second connecting rod, the auxiliary backing plate, the support seat where the hinge point E and the hinge point F are located form a four-bar linkage structure, ensuring that the vehicle bottom backing plate is in a vertical state when it is close to the carriage.
[0025] 6. An electromagnet is added to the main backing plate to ensure that the main backing plate and the carriage will not separate.
[0026] Based on the above reasons, the utility model can be widely promoted in the fields of large-angle tipplers, etc. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners
[0034] It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other. The following will refer to the drawings and combine the embodiments to detail the present invention. To make the objectives, 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 with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way limits the present invention and its application or use. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.
[0035] Such asFigures 1 to 5 As shown in the figure, a tipping plate device of a dumper suitable for complete discharging includes a main back plate 1 arranged on the tipping side of the dumper and a car body bottom back plate mechanism 2 arranged on the non-tipping side of the dumper; the car body bottom back plate mechanism 2 is installed on the loading platform 3 of the dumper;
[0036] The car body bottom back plate mechanism 2 includes a car body bottom back plate 21, the car body bottom back plate 21 extends along the length direction of the vehicle, and the car body bottom back plate 21 can adopt a one-piece structure or a segmented structure. A plurality of tipping units are arranged along the length direction of the car body bottom back plate 21, and the tipping units are used to tip the car body bottom back plate 21 so that it closely abuts against the vehicle being tipped by the dumper.
[0037] The tipping unit includes a hydraulic cylinder 22 and a connecting rod group 23; one end of the hydraulic cylinder 22 is hinged to a hinge point A fixed on the side wall of the loading platform 3, and the hinge point A is arranged on a first hinge seat 31 fixed on the side wall of the loading platform 3. The other end of the hydraulic cylinder 22 is hinged to a hinge point B arranged on the car body bottom back plate 21. The connecting rod group 23 includes a first connecting rod 231 and a second connecting rod 232. The first connecting rod 231 and the second connecting rod 232 are arranged in parallel, and one ends of the first connecting rod 231 and the second connecting rod 232 are respectively hinged to a hinge point C and a hinge point D arranged on the car body bottom back plate 21, and the other ends are respectively hinged to a hinge point E and a hinge point F fixed on the side wall of the loading platform 3. The hinge point E and the hinge point F are arranged on a second hinge seat 32 fixed on the side wall of the loading platform 3. The hinge point C, the hinge point D, the hinge point E and the hinge point F form the four vertices of a parallelogram, forming a four-link structure. The hinge point B, the hinge point C and the hinge point D form the three vertices of an obtuse triangle, and the hinge point B is an acute angle. As Figure 5 shown in the figure, the hinge point D is higher than the hinge point C and the hinge point B, and the hinge point E is higher than the hinge point A.
[0038] In the working state, the hydraulic cylinder 22 works, and its telescopic rod extends, so that the car body bottom back plate 21 swings from the horizontal state around the hinge point E and the hinge point F to the vertical direction until the car body bottom back plate 21 closely abuts against the carriage, and the abutment is completed on the non-tipping side. When the tipping work of the dumper does not reach 180°, the main back plate 1 plays a certain supporting role. When it exceeds 180°, the car body bottom back plate 21 plays a certain supporting role, ensuring that the vehicle will not derail due to lack of support during large-angle tipping, or the pin shaft at the connection between the bogie and the carriage will not be deformed or broken.
[0039] In order to further ensure that the main backboard 1 can always closely adhere to the carriage, an electromagnet (not shown in the figure) is installed on the main backboard 1, so that when the car overturns more than 180°, the carriage can also be adsorbed on the main backboard 1. The electromagnet can be electrically connected to the control system by means of a solenoid valve or other devices to complete its adsorption or not. An auxiliary backboard 11 is arranged below the main backboard 1, and the auxiliary backboard 11 faces the bottom backboard 21 in the state of closely adhering to the vehicle.
[0040] When the bottom backboard mechanism 2 is in a non-closely adhering state (horizontal state), the bottom backboard mechanism 2 is lower than or in the plane of the loading platform 3, thereby ensuring that the car dumper can smoothly enter and exit the vehicle. A maintenance platform 4 is arranged beside the loading platform 3, and the maintenance platform 4 is provided with an avoidance groove or an avoidance hole at the bottom backboard mechanism 2, thereby ensuring that the bottom backboard mechanism 2 will not interfere with the maintenance platform 4 during the process of flipping and falling.
[0041] As Figure 3 described, when the vehicle overturned by the car dumper is an open-top railway wagon, the bottom backboard 21 closely adheres to the lower part of the carriage of the open-top railway wagon after flipping; as Figure 4 described, when the vehicle overturned by the car dumper is an open-top container car, the bottom backboard 21 closely adheres to the side wall of the car body of the open-top container car after flipping.
[0042] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
