Description

Technical Field

[0001] The present invention relates to an overall transformation method for a tilting car dumper based on the preservation of infrastructure, and is specifically applicable to the transformation of a tilting car dumper so that it can simultaneously adapt to the dumping operations of railway gondola cars and containers. Background Art

[0002] As the core equipment for unloading large quantities of railway goods, the traditional design of a tilting car dumper mainly targets the dumping requirements of a single vehicle type (such as C60-C80 series gondola cars), and uses mechanical or hydraulic car clamping devices to fix the vehicle. However, with the diversified development of the railway freight structure, the proportion of container transportation has increased significantly. The old tilting car dumper has a limited range of car clamping force adjustment and can only adapt to gondola cars of specific sizes, and cannot be compatible with the box structure of containers. At the same time, the early car dumpers did not consider the compatibility requirements of multiple vehicle types, and the key structural parameters such as the foundation of the drive device and the hinge points of the car clamping arms are fixed, making it difficult to achieve unified adaptation of gondola cars and containers through local transformation. Moreover, when unloading containers, the force distribution on the contact surface between the container body and the car dumper is significantly different from that of gondola cars. The traditional tilting car dumper cannot match the cargo form of containers, and there is a risk of tipping over or bulk material leakage.

[0003] The existing tilting car dumper is unable to cope when facing container dumping operations. Replacing the car dumper capable of performing container dumping operations not only requires replacing the car dumper machinery, but also requires re-laying the railway tracks, coal screens supporting the car dumper, as well as reconstructing the civil engineering foundation of the car dumper and re-laying it. The costs required for reconstructing the civil engineering foundation, re-laying the supporting railway tracks and coal screens are much higher than the cost of replacing the car dumper machinery. Moreover, after replacing the new car dumper, large-scale coal transportation lines such as the belt conveyor corridors already built under the civil engineering foundation will also face failure, resulting in huge cost waste. Therefore, the cost for enterprises to replace the car dumper is extremely high, leading to a low willingness of enterprises to replace the car dumper. At the same time, the new car dumper and its supporting equipment have a larger footprint. Due to the limitation of the original civil engineering area of the car dumper, it is impossible to directly replace the new car dumper. Therefore, an overall transformation method for a tilting car dumper based on the preservation of infrastructure is needed to transform the existing tilting car dumper so that it can simultaneously adapt to the dumping operations of railway gondola cars and containers. Summary of the Invention

[0004] The purpose of the present invention is to overcome the problem in the prior art that the existing tilting car dumper is unable to cope when facing container dumping operations, and provides an overall transformation method for a tilting car dumper based on the preservation of infrastructure, so that the transformed tilting car dumper can simultaneously adapt to the dumping operations of railway gondola cars and containers.

[0005] To achieve the above purpose, the technical solution of the present invention is:

[0006] The present invention provides an overall transformation method for a tilting car dumper based on infrastructure retention. The tilting car dumper includes a car-resting beam, a car-supporting platform, and two oppositely arranged end discs. A car-pressing device is arranged on the car-resting beam. Both ends of the car-resting beam and the car-supporting platform are respectively connected to an end disc. The center of each end disc is rotationally matched with a support seat through a main shaft. The support seat is arranged on the installation foundation at the zero-meter level. A pit layer is arranged below the zero-meter level. The bottom of the end disc is located in the pit layer. The bottom of the end disc is in transmission cooperation with a driving mechanism through a gear and a rack. The driving mechanism is used to drive the end disc to rotate. The driving mechanism is arranged on the installation foundation in the pit layer. A detachable steel structure is fixedly arranged above the driving mechanism.

Lift the main shaft and end plate connected as a whole, and position the main shaft and end plate connected as a whole so that the main shaft is located at the center hole on the top of the support base, and connect the main shaft and the support base.

[0024] The installation of the new car-resting beam includes:

[0025] Lift the new car-resting beam to the installation position between the two end plates and align it to ensure that the gap between the new car-resting beam and the end plate meets the design requirements. Use connecting plates to connect and fix the two ends of the new car-resting beam to the two end plates respectively.

[0026] A receiving groove penetrating the front and rear end faces is provided on the new car-resting beam, and a middle groove penetrating the upper and lower end faces is provided on the front end face of the new car-resting beam;

[0027] The modified car-resting device includes a car-resting plate and a pushing plate. The car-resting plate and the pushing plate are both located in the middle groove. The car-resting plate is used to abut against the side of the railway open wagon or container. The back of the car-resting plate is connected to the front ends of the first telescopic cylinder and the second telescopic cylinder. The first telescopic cylinder is arranged in the receiving groove, and the rear end of the first telescopic cylinder is connected to the rear part of the new car-resting beam. The second telescopic cylinder is located above the new car-resting beam, and the rear end of the second telescopic cylinder is connected to the top of the new car-resting beam;

[0028] The pushing plate is used to abut against the side of the flat car carrying the container. The pushing plate is located below the car-resting plate. The pushing plate is connected to the front end of the third telescopic cylinder. The third telescopic cylinder is located below the new car-resting beam, and the rear end of the third telescopic cylinder is connected to the bottom of the new car-resting beam.

[0029] The container pressing device is arranged at the entrance and exit of the end plate for the railway open wagon or the flat car carrying the container to pass through. The container pressing device includes a car pressing arm, a car pressing fork and a fourth telescopic cylinder. The lower end of the car pressing arm is hinged to a hinge seat fixed on the end plate. The upper end of the car pressing arm is hinged to the top of the car pressing fork. The car pressing fork is used to press the top of the container. The upper end of the car pressing arm is hinged to one end of the fourth telescopic cylinder. The other end of the fourth telescopic cylinder is hinged to an oil cylinder seat fixed on the end plate. The oil cylinder seat is arranged above the hinge seat.

[0030] The container holding device includes an auxiliary pushing block and a fifth telescopic cylinder. The front surface of the auxiliary pushing block is used to hold the side of the container, and the back surface of the auxiliary pushing block is connected to one end of the fifth telescopic cylinder. The fifth telescopic cylinder is located inside the end plate, and the other end of the fifth telescopic cylinder is connected to the end plate.

[0031] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0032] 1. In the overall transformation method of the side-tilting dumper retained based on infrastructure construction of the present invention, the installation foundation for the driving device is set in a pit below the zero-meter level, and the pit has an open design above. A detachable steel structure is fixedly arranged above the driving mechanism, and the upper surface of the detachable steel structure is on the same plane as the zero-meter level. The detachable steel structure plays a supporting role during the operation of the dumper and does not affect the operation of railway gondolas or flat cars carrying containers. Moreover, the detachable steel structure is convenient for disassembly and assembly. During the transformation of the dumper, when demolishing the dumper, the detachable steel structure is removed so that the lifting hook of the crane can pass through the installation area of the detachable steel structure to lift the driving device out of the pit; when reinstalling the transformed dumper, the detachable steel structure is not installed first. After the driving device is adjusted, installed in place and fixed, the detachable steel structure is then installed and fixed. The setting of the detachable steel structure makes the demolition and modification of the side-tilting dumper more convenient on the premise of not affecting the operation of railway gondolas or flat cars carrying containers. Therefore, in this method, a detachable steel structure is fixedly arranged above the driving mechanism, and the setting of the detachable steel structure makes the demolition and modification of the side-tilting dumper more convenient on the premise of not affecting the operation of railway gondolas or flat cars carrying containers.

[0033] 2. In the overall transformation method of the side-tilting dumper retained based on infrastructure construction of the present invention, first, the support seats are positioned and fixed on the installation foundation at the zero-meter level, and then the end plates are connected to the support seats through the main shafts, so that the end plates, main shafts, and support seats are linked into a whole. Subsequently, the car-resting beams are installed, and the two end plates are connected into a whole through the car-resting beams to complete the installation of the main body of the dumper's rotating structure. In order to ensure the cooperation between the dumper and the driving mechanism, after installing the main body of the dumper's rotating structure, a lifting device is used to lift the driving mechanism and adjust the driving mechanism until the gear at the output end of the driving mechanism meshes with the rack on the end plate. Subsequently, the driving mechanism is firmly fixed to the installation foundation in the pit layer to ensure the precise docking between the driving mechanism and the end plate. Therefore, in this method, the main body of the rotating structure composed of end plates and car-resting beams is installed first, then the driving mechanism is lifted, and the position and attitude of the driving mechanism are adjusted. After the adjustment is completed, the driving mechanism is firmly fixed to the installation foundation in the pit layer, which can ensure the precise docking between the driving mechanism and the end plate.

[0034] 3. In the overall renovation method of the tilting car dumper based on infrastructure retention of the present invention, after installing the installation trailer platform, a car pressing device and the renovated car abutting device are installed on the car abutting beam, and a container pressing device and a container abutting device are installed on the end disc. Among them, the car pressing device is the structure originally used in the tilting car dumper to press the open-top railway wagon. The renovated car abutting device includes a car abutting plate that can be used to abut the side of the open-top railway wagon or the container, and a pushing plate dedicated to abutting the side of the flat car carrying the container. The container pressing device is dedicated to pressing the two ends of the top of the container, and the container abutting device is dedicated to abutting the side of the container. The renovated tilting car dumper can simultaneously adapt to the dumping operations of both open-top railway wagons and containers. Therefore, in this method, the tilting car dumper is renovated, making full use of the space at the entrance and exit of the end disc of the car dumper, adding a container pressing device and a container abutting device, and renovating the original car abutting device. The renovated tilting car dumper can simultaneously adapt to the dumping operations of both open-top railway wagons and containers.

[0035] 4. In the overall renovation method of the tilting car dumper based on infrastructure retention of the present invention, the car abutting device, the container pressing device, the container abutting device, and the renovated driving mechanism are all hydraulically driven. The pressure for hydraulically driving and pushing the open-top railway wagon or the container is controllable, which can better meet the current railway car inspection standards. Therefore, in this design, the renovated car abutting, abutting, and end disc driving devices are all hydraulically driven, and their pressure is controllable, which can better meet the current railway car inspection standards.

Detailed implementation mode

[0044] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation modes.

[0045] See Figures 1 to 6 , based on the overall transformation method of the tilting dumper reserved for infrastructure construction, the tilting dumper includes a car leaning beam 2, a car supporting platform 3 and two relatively arranged end plates 1. A car pressing device is arranged on the car leaning beam 2, and the car pressing device is used to press the top of the railway gondola car. Both ends of the car leaning beam 2 and the car supporting platform 3 are respectively connected to an end plate 1. The center of each end plate 1 is rotationally matched with a support seat 4 through a main shaft 41. The support seat 4 is arranged on the installation foundation at the zero-meter level. A pit layer is arranged below the zero-meter level. The bottom of the end plate 1 is located in the pit layer. The bottom of the end plate 1 is in transmission cooperation with the driving mechanism 5 through gears and racks. The driving mechanism 5 is used to drive the end plate 1 to rotate. The driving mechanism 5 is arranged on the installation foundation in the pit layer. A detachable steel structure 6 is fixedly arranged above the driving mechanism 5. The upper surface of the detachable steel structure 6 is on the same plane as the zero-meter level.

[0046] In the civil engineering foundation of the dumper, the zero-meter level is the ground reference level. The transmission device is installed below it through a pit structure to ensure that the mechanical structure for driving the end plate to rotate forms a spatial layout with the ground layer. The pit layer is located in the underground space and is the area in the dumper structure for accommodating the driving mechanism (such as motors, reducers, etc.).

[0047] The transformation method includes a demolition step and a modification step;

[0048] The demolition step includes:

[0049] Before demolishing the original tilting dumper, it is necessary to first fix the two end plates 1 with a support device to prevent the end plates from tipping and rotating during the disassembly process.

[0050] Successively demolish the car supporting platform 3, the car leaning beam 2 and the car pressing device and car leaning device installed on the car leaning beam 2, the end plate 1, the main shaft 41, the support seat 4, demolish the detachable steel structure 6, and the driving mechanism 5.

[0051] Specifically, first demolish the car supporting platform 3;

[0052] Subsequently, remove the car pressing device from the car leaning beam 2. If the car leaning beam 2 is originally provided with car leaning devices such as car leaning plates, etc., then the car leaning devices also need to be removed from it. Subsequently, remove the car leaning beam 2 to disconnect the two end plates 1;

[0053] Subsequently, remove the two end plates 1 and the main shaft 41 used to connect the end plate 1 and the support seat respectively, separate the end plate from the support seat 4, and then remove the support seat 4 from the foundation at the zero-meter level;

[0054] Then, remove the detachable steel structure 6 to expose the drive mechanism 5 located in the pit. Remove the drive mechanism 5 located below the detachable steel structure 6 from the installation foundation in the pit layer, and use the overhead crane in the car dumper room to lift the drive mechanism 5 and remove it from the pit.

[0055] As Figure 1 shown, the car pressing device is a plurality of car pressing arms arranged in sequence along the length direction of the car leaning beam. The top of the car pressing arm is hinged to the top of the inverted V-shaped car pressing fork, and the car pressing fork connected to the car pressing arm is used to press the top of the open-top railway wagon.

[0056] The modification steps include:

[0057] Arrange the new drive mechanism 5 on the installation foundation in the pit layer. Before modifying the side-tilting car dumper, its drive mechanism 5 can be a drive mechanism based on the hydraulic transmission principle or a drive mechanism using an electric motor. After modification, we use a new drive mechanism 5 based on the hydraulic transmission principle.

[0058] Install the support seat 4, the main shaft 41, the end plate 1 and the new car leaning beam 2 in sequence.

[0059] Specifically, the installation of the support seat 4, the main shaft 41, and the end plate 1 includes:

[0060] Determine the installation position of the support seat 4, position the support seat 4 and fix it on the installation foundation at the zero-meter level;

[0061] Install the main shaft 41 at the center of the end plate 1 and fix it. Lift the main shaft 41 and the end plate 1 connected as a whole, and determine the installation position of the main shaft 41 and the end plate 1 connected as a whole. Position the main shaft 41 and the end plate 1 connected as a whole so that the main shaft 41 is located at the center mounting hole on the top of the support seat 4. Subsequently, connect the main shaft 41 and the support seat 4 so that the main shaft 41 and the support seat 4 can rotate in cooperation.

[0062] After installing the end plate 1, temporarily fix the end plate 1 to the ground with steel profiles to prevent the end plate from tipping or rotating.

[0063] The installation of the new car leaning beam 2 includes:

[0064] After both end plates 1 are installed, lift the new car-relying beam 2 to the installation position between the two end plates 1 and align it to ensure that the gap between the new car-relying beam 2 and the end plate 1 meets the design requirements. Then, use connecting plates to connect and fix the two ends of the new car-relying beam 2 to the two end plates 1 respectively.

[0065] The support base 4, the main shaft 41, the end plate 1, and the new car-relying beam 2 are the rotating parts of the dumper. After this part is installed, it is necessary to ensure that the driving mechanism 5 can stably drive it to rotate.

[0066] Since the detachable steel structure 6 is not installed at this time, the upper part of the driving mechanism 5 is open, and the overhead crane hook can pass through the installation area of the detachable steel structure 6 and reach above the transmission device to lift the driving mechanism 5 in order to adjust the position and attitude of the driving mechanism 5.

[0067] Use the lifting device to lift the driving mechanism 5 and adjust the driving mechanism 5 until the gear at the output end of the driving mechanism 5 meshes with the rack on the end plate 1. Then, firmly fix the driving mechanism 5 to the installation foundation in the pit floor. At this time, the positioning installation of the driving mechanism 5 is completed, and the driving mechanism 5 can drive the end plate 1 to rotate, thereby driving the whole composed of the two end plates 1 and the new car-relying beam 2 to rotate to perform the dumping task. Subsequently, install and fix the detachable steel structure 6.

[0068] For the modified side-tilting dumper, since its driving mechanism 5 uses hydraulic control, the modified side-tilting dumper no longer requires a stop.

[0069] The ground stop is mainly used for non-hydraulically driven dumpers. Its function is that when the dumper is turning back to zero degree, the pawl on the mechanical car clamping device contacts the stop, and the pawl gradually disengages from the ratchet teeth on the end plate, driving the clamping device to disengage from the open-top car to achieve unclamping of the open-top car. As Figure 4 shown, there was originally a stop installation foundation for installing the stop in the pit. For this stop installation foundation, it can be demolished.

[0070] After installing the driving mechanism 5 and the detachable steel structure 6, continue to install the car-carrying platform 3, and install the car pressing device and the modified car-relying device on the new car-relying beam 2, and install the container pressing device and the container resisting device on the end plate 1, so that the dumper can adapt to the dumping operations of both railway open-top cars and containers at the same time.

[0071] The modified car-leaning device includes a car-leaning plate 7 and a pushing plate 8. The car-leaning plate 7 is used to abut against the side of an open-top railway wagon or a container. The back surface of the car-leaning plate 7 is connected to the front ends of a first telescopic cylinder 71 and a second telescopic cylinder 72. The first telescopic cylinder 71 is arranged in a receiving groove 21 that penetrates the front and rear end faces of the new car-leaning beam 2, and the rear end of the first telescopic cylinder 71 is connected to the rear part of the car-leaning beam 2. The second telescopic cylinder 72 is located above the new car-leaning beam 2, and the rear end of the second telescopic cylinder 72 is connected to the top of the new car-leaning beam 2.

[0072] Since the first telescopic cylinder 71 is arranged in the receiving groove 21 that penetrates the front and rear end faces of the new car-leaning beam 2 and the second telescopic cylinder 72 is located above the new car-leaning beam 2, neither the first telescopic cylinder 71 nor the second telescopic cylinder 72 occupies the space below the new car-leaning beam 2, and space is left below the new car-leaning beam 2 for arranging the driving mechanism of the pushing plate 8.

[0073] The pushing plate 8 is used to abut against the side of a flat car carrying a container. The pushing plate 8 is located below the car-leaning plate 7 and is connected to the front end of a third telescopic cylinder 81. The third telescopic cylinder 81 is located below the new car-leaning beam 2, and the rear end of the third telescopic cylinder 81 is connected to the bottom of the new car-leaning beam 2.

[0074] To facilitate the arrangement of the modified car-leaning device, after the demolition step is completed, the car-leaning beam 2 is modified. A receiving groove 21 that penetrates the front and rear end faces of the car-leaning beam 2 is opened in the middle of the car-leaning beam 2 to accommodate the first telescopic cylinder 71. At the same time, since the end disc of the side-tilting dumper has a small size and due to the restriction of its eccentricity, the distance between the rotation axis of the dumper rotor and the center line of the open-top wagon cannot be made too large to reduce the resistance moment during the rotation of the dumper. Therefore, the maximum distance between the main shaft of the side-tilting dumper and the outer side of the open-top railway wagon is very small. To arrange the hydraulically controlled car-leaning plate 7 and pushing plate 8 in this narrow space, we optimized the car-leaning beam. The middle part of the car-leaning beam adopts a concave structure, that is, a middle concave groove 22 that penetrates the upper and lower end faces of the car-leaning beam 2 is provided on the front end face of the car-leaning beam 2. The space inside the middle concave groove 22 is used to install the car-leaning plate 7 and the pushing plate 8. The front end face of the car-leaning beam 2 is the end face of the car-leaning beam 2 close to the open-top railway wagon or the container.

[0075] To ensure that the third telescopic cylinder 81 and the pushing plate 8 are reasonably stressed, the pushing plate 8 is connected to the bottom of the car body support beam 2 through a four-bar linkage structure. Specifically, the four-bar linkage structure includes a swing bracket 82, a first swing rod 83, a connecting bracket 84, and a second swing rod 85. The pushing plate 8 is fixedly connected to the front part of the swing bracket 82. The front part of the swing bracket 82 is hinged to the bottom of the first swing rod 83 through a hinge shaft. The top of the first swing rod 83 is hinged to the front part of the connecting bracket 84 through a hinge shaft. The connecting bracket 84 is fixed to the bottom of the car body support beam 2. The rear part of the connecting bracket 84 is hinged to the top of the second swing rod 85 through a hinge shaft. The bottom of the second swing rod 85 is hinged to the rear part of the swing bracket 82 through a hinge shaft.

[0076] The container pressing device is arranged at the entrance and exit of the end plate 1 for the passage of open-top railway wagons or flat wagons for consigning containers. The container pressing device includes a car body pressing arm 11, a car body pressing fork 12, and a fourth telescopic cylinder 13. The lower end of the car body pressing arm 11 is hinged to a hinge seat 14 fixed on the end plate 1. The upper end of the car body pressing arm 11 is hinged to the top of the car body pressing fork 12. The car body pressing fork 12 is used to press the top of the container. The upper end of the car body pressing arm 11 is hinged to one end of the fourth telescopic cylinder 13. The other end of the fourth telescopic cylinder 13 is hinged to an oil cylinder seat 15 fixed on the end plate 1. The oil cylinder seat 15 is arranged above the hinge seat 14.

[0077] The container abutting device includes an auxiliary pushing block 16 and a fifth telescopic cylinder 17. The front surface of the auxiliary pushing block 16 is used to abut against the side surface of the container. The back surface of the auxiliary pushing block 16 is connected to one end of the fifth telescopic cylinder 17. The fifth telescopic cylinder 17 is located inside the end plate 1. The other end of the fifth telescopic cylinder 17 is connected to the end plate 1. To ensure the stable operation of the container abutting device, a guiding device for guiding the telescopic direction of the fifth telescopic cylinder 17 can be arranged inside the end plate 1.

[0078] After installing the car body pressing device and the modified car body device on the car body support beam 2, and installing the container pressing device and the container abutting device on the end plate 1, the installation of the main body of the car dumper is completed. Subsequently, the hydraulic control system and the electrical control system of the car dumper are installed, and the whole machine is debugged.

[0079] The principle of the present invention is described as follows:

[0080] In the civil engineering foundation of the car dumper, the zero-meter layer is the ground reference layer. The transmission device is installed below it through a pit structure to ensure that the mechanical structure for driving the rotation of the end plate forms a spatial layout with the ground layer. The pit layer is the underground space in the car dumper structure for accommodating the driving mechanism (such as motors, reducers, etc.).

[0081] This method modifies the tilting dumper. Based on the structure of the original tilting dumper, at the entrance and exit of the end plate 1 where the railway gondola car or the flat car for transporting containers passes through, a container pressing device is added by utilizing the space at the entrance and exit, and a container resisting device is added by utilizing the space inside the end plate. Moreover, the car-resting system of the dumper is improved so that the modified car-resting system can resist both the container and the flat car transporting the container simultaneously. At the same time, during the modification, the rotating structure main body of the tilting dumper is not replaced, and the original dumper civil engineering foundation can be fully utilized to enable the tilting dumper to adapt to the dumping operations of railway gondola cars and containers at the lowest cost.

[0082] Embodiment 1:

[0083] The overall modification method of the tilting dumper based on the retention of infrastructure. The tilting dumper includes a car-resting beam 2, a car-carrying platform 3, and two relatively arranged end plates 1. A car-pressing device is arranged on the car-resting beam 2. The two ends of the car-resting beam 2 and the car-carrying platform 3 are respectively connected to an end plate 1. The center of each end plate 1 is rotationally matched with a support seat 4 through a main shaft 41. The support seat 4 is arranged on the installation foundation at the zero-meter level. There is a pit layer below the zero-meter level. The bottom of the end plate 1 is located in the pit layer. The bottom of the end plate 1 is in transmission cooperation with a driving mechanism 5 through gears and racks. The driving mechanism 5 is used to drive the end plate 1 to rotate. The driving mechanism 5 is arranged on the installation foundation in the pit layer. A detachable steel structure 6 is fixedly arranged above the driving mechanism 5. The upper surface of the detachable steel structure 6 is on the same plane as the zero-meter level;
