[0001] The present invention relates to the field of the railway coal unloading system of a thermal power plant, and particularly relates to an installation method for a side-tilting car dumper. Background Art

[0002] The CFH-II type side-tilting car dumper body is a mechanical equipment for unloading bulk materials that adopts a sectional box-type structure for assembly, gravity car clamping, and mechanical locking, and omits the hydraulic system and numerous sensing elements. Its prominent features are simple equipment structure, strong rigidity, large anti-deformation force, durability, less maintenance workload and cost, low cost, and strong environmental adaptability. Since the production years of side-tilting car dumpers are generally relatively early, in recent years, in order to better adapt to the changes in railway gondola car models, there have been more and more renovation projects for side-tilting car dumpers.

[0003] During the renovation process of the car dumper, it is often necessary to disassemble the car clamping arms on the car dumper. After replacing or renovating the car clamping arms, the car clamping arms are reinstalled on the car dumper. In this process, it is necessary to disassemble and then reconnect the car clamping arms and the car clamping beams. However, after the car clamping arms and the car clamping beams on the car dumper are reconnected, installation errors are likely to occur, resulting in a situation where it is difficult to keep the postures of multiple car clamping arms connected to the car clamping beam consistent or the pawls on the car clamping beam cannot cooperate with the ratchet teeth on the end disc of the car dumper. Therefore, after replacing components or completing the renovation, when reinstalling the car clamping beam and the car clamping arms, it is necessary to adjust the positions of components such as the car clamping arms, the car clamping beam, and the ratchet blocks to reduce installation errors. Therefore, there is a need for an installation method for a side-tilting car dumper that can quickly and accurately adjust and install components such as the car clamping arms, the car clamping beam, and the ratchet blocks on the side-tilting car dumper after disassembly and repair or renovation operations, so that the components such as the car clamping arms, the car clamping beam, the ratchet teeth, and the ratchet blocks on the installed side-tilting car dumper can cooperate well, thereby more efficiently completing the renovation task. Summary of the Invention

[0047] S224. Fix the ratchet blocks after the position adjustment on the end plates.

[0048] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0049] 1. In the installation method of a side-tilting dumper of the present invention, each car clamping arm is pre-hinged to the main beam through the car clamping arm pin shaft, and then the car clamping beam is positioned. When positioning the car clamping beam, taking the track surface of the dumper as the reference surface, rotate each car clamping arm to adjust the position of each car clamping arm, and at the same time measure the relative height between the equalizing beam pin shaft on each car clamping arm and the track surface, so that the relative height between the equalizing beam pin shaft on each car clamping arm and the track surface is the same. Then keep the positions of each car clamping arm unchanged and adjust the car clamping beam according to the positions of each car clamping arm. After adjusting the position of the car clamping beam, spot-weld and fix each car clamping arm to the car clamping beam. After spot-welding and fixing, each car clamping arm is connected to the car clamping beam, and the postures of each car clamping arm can be kept consistent; at the same time, after adjusting the relative positions of each car clamping arm and the car clamping beam, adjust and install the ratchet blocks on the end plate according to the position of the ratchet pawl seat at the end of the car clamping beam to ensure that the ratchet blocks can be meshed well with the ratchet pawls on the ratchet pawl seat. Therefore, in this design, first adjust the postures of each car clamping arm and make the relative height between the equalizing beam pin shaft on each car clamping arm and the track surface the same, then adjust the position of the car clamping beam based on the positions of each car clamping arm, and then adjust and install the ratchet blocks on the end plate according to the position of the ratchet pawl seat at the end of the car clamping beam, which can ensure that the postures of each car clamping arm are consistent, and the ratchet pawls installed on the ratchet pawl seat can be meshed well with the ratchet blocks on the end plate.

[0050] 2. In the installation method of a tilting car dumper according to the present invention, when adjusting the position of the car clamping beam, first tap the equalizing beam pin and the car clamping arm pin on the same car clamping arm. On the premise that the pins do not slip out of the pin holes, move the equalizing beam pin and the car clamping arm pin a certain distance to the same side of the car clamping arm, so that a part of the equalizing beam pin and the car clamping arm pin extends out of the pin holes on the car clamping arm and is exposed outside the car clamping arm. Then, use the auxiliary adjustment tooling, and sleeved the first positioning bushing on the auxiliary adjustment tooling on the section of the equalizing beam pin exposed outside the car clamping arm, and sleeved the second positioning bushing on the auxiliary adjustment tooling on the section of the car clamping arm pin exposed outside the car clamping arm, then the auxiliary adjustment tooling can be quickly and stably installed on the car clamping arm; at the same time, after the auxiliary adjustment tooling is installed on the car clamping arm, the position of the first positioning edge on the auxiliary adjustment tooling relative to the car clamping arm is determined, and the position of the car clamping beam can be accurately positioned through the first positioning edge. Therefore, the auxiliary adjustment tooling in this design can be quickly and stably installed on the car clamping arm, and the position of the car clamping beam can be quickly positioned through the auxiliary adjustment tooling.

[0051] 3. In the installation method of a tilting car dumper according to the present invention, since there is a certain distance between the outermost car clamping arm and the end of the car clamping beam in the tilting car dumper, in order to more accurately adjust the position of the car clamping beam, during the fine alignment of the car clamping beam, the auxiliary adjustment tooling is installed on the car clamping arm near the end of the car clamping beam through the connecting shaft. Since the connecting shaft has a certain length, at this time, the connecting shaft can make a certain distance between the auxiliary adjustment tooling and the car clamping arm on which the auxiliary adjustment tooling is installed, so that the pawl positioning plate at the bottom of the auxiliary adjustment tooling is close to the pawl seat arranged at the end of the car clamping beam, which is convenient for accurately micro-adjusting the position of the car clamping beam and then making the position of the pawl seat meet the installation requirements; at the same time, since the length of the connecting shaft is set according to the assembly requirements of the car clamping beam and the pawl seat, when the pawl seat arranged at the end of the car clamping beam is in contact with the pawl positioning plate, the relative position between the pawl seat arranged at the end of the car clamping beam and the end plate meets the assembly requirements. Furthermore, after the pawl is installed on the pawl seat, the pawl can cooperate with the ratchet teeth on the end plate. Therefore, by installing the auxiliary adjustment tooling on the car clamping arm near the end of the car clamping beam through the connecting shaft, the pawl positioning plate at the bottom of the auxiliary adjustment tooling can be close to the pawl seat arranged at the end of the car clamping beam, which is convenient for accurately adjusting the position of the pawl seat, and then making the relative position between the pawl seat and the end plate meet the assembly requirements.

[0052] 4. In the installation method of a tilting car dumper according to the present invention, two pawl positioning plates are respectively installed on two pawl seats at both ends of the car clamping beam, and the symmetry axes of two template shaft holes are marked on the pawl positioning plates. The positions of the pawl positioning plates are adjusted so that the two template shaft holes on the pawl positioning plates are aligned with the two installation shaft holes on the corresponding pawl seats, and then the pawl positioning plates are fixed by electric welding. When installing the ratchet blocks, the symmetry axes of the ratchet blocks are marked on the ratchet blocks. Subsequently, the positions of the ratchet blocks are adjusted so that the symmetry axes of the ratchet blocks are aligned with the symmetry axes of the two template shaft holes on the pawl positioning plates, and at the same time, the ratchets at the top of the ratchet blocks are closely attached to the positioning arc edges at the bottoms of the corresponding pawl positioning plates. By using the markings on the pawl positioning plates and the ratchet blocks, as well as the positioning arc edges at the bottoms of the pawl positioning plates, the positions of the ratchet blocks can be adjusted quickly and accurately. After the installation of the car dumper is completed, the pawls at both ends of the car clamping beam can be meshed with the ratchet blocks on the two end discs simultaneously. Therefore, in this design, by using the markings on the pawl positioning plates and the ratchet blocks, as well as the positioning arc edges at the bottoms of the pawl positioning plates, the positions of the ratchet blocks can be adjusted quickly and accurately. After the installation of the car dumper is completed, the pawls at both ends of the car clamping beam can be meshed with the ratchet blocks on the two end discs simultaneously.

[0066] The installation method includes:

[0067] S1. Hinge the modified car clamping arms 10 to the main beam 40 through the car clamping arm pin shafts 60, adjust the relative positions of the car clamping beam 20 and the car clamping arms 10, and then use high-strength bolts to connect and fix the bottoms of the car clamping arms 10 to the car clamping beam 20;

[0068] S2. Adjust the positions of the ratchet blocks 90 according to the positions of the pawl seats 80 fixed at the ends of the car clamping beam 20, and fix the ratchet blocks 90 at the adjusted positions on the end plates 30.

[0069] In the step S1, adjusting the relative positions of the car clamping beam 20 and the car clamping arms 10 includes positioning the car clamping beam 20 and precisely aligning the car clamping beam 20.

[0070] The positioning of the car clamping beam 20 includes the following steps:

[0071] S11. Determine the track surface of the dumper, where the track surface is the top surface of the walking track for the gondola car to enter the dumper.

[0072] S12. Rotate each clamping arm 10 with the clamping arm pin shaft 60 as the rotation center to adjust the position of each clamping arm 10. At the same time, measure the relative height between the equalizing beam pin shaft 70 on each clamping arm 10 and the track surface, so that the relative height between the equalizing beam pin shaft 70 on each clamping arm 10 and the track surface is the same, and the adjustment of the position of each clamping arm 10 is completed.

[0073] S13. After the adjustment of the position of each clamping arm 10 is completed, keep the position of each clamping arm 10 unchanged, and adjust the position of the clamping beam 20 according to the position of each clamping arm 10.

Subsequently, adjust the position of the clamping beam so that when the auxiliary adjustment tooling is installed on any one clamping arm 10, the side part of the clamping beam 20 can be in contact with the first positioning edge 41 at the bottom of the auxiliary adjustment tooling. Since the clamping beam 20 is a cross-sectional square crossbeam, when the auxiliary adjustment tooling is installed on any one clamping arm 10, the side part of the clamping beam 20 can be in contact with the first positioning edge 41 at the bottom of the auxiliary adjustment tooling, which can make the clamping beam 20 as parallel as possible to the main beam of the dumper.

[0080] The auxiliary adjustment tooling is designed and manufactured according to the structures of the car clamping arms 10 and car clamping beams 20 of the dumper and the installation requirements.

[0087] S15. After spot welding and fixing each clamping arm 10 to the clamping beam 20, install the auxiliary adjustment tooling on the two clamping arms 10 closest to the end of the clamping beam 20 respectively through the connecting shaft 6;

[0088] S16. Use tools such as a jack to finely adjust the clamping beam 20, and finely adjust the positions at both ends of the clamping beam 20, so that when the auxiliary adjustment tooling is installed on any one of the clamping arms 10 closest to the end plate 30, the pawl positioning plate 5 in the auxiliary adjustment tooling can be in contact with the closest pawl seat 80, and the two template shaft holes 51 on the pawl positioning plate 5 can be aligned with the two mounting shaft holes 801 on the closest pawl seat 80. As Figure 1 、 Figure 3 shown, multiple clamping arms 10 are arranged in parallel on the dumper, and the multiple clamping arms 10 arranged in parallel are connected by the clamping beam 20. One pawl seat 80 is provided at each end of the clamping beam 20. The clamping beam 20, the two pawl seats 80 and the multiple clamping arms 10 are all arranged between the two end plates 30. There are two clamping arms 10 closest to the end plate 30 among the multiple clamping arms 10 arranged in parallel. When the auxiliary adjustment tooling is installed on one of the clamping arms 10 closest to the end plate 30, install the auxiliary adjustment tooling on the side of the clamping arm 10 close to the end plate 30. At this time, the pawl positioning plate 5 on the auxiliary adjustment tooling is close to the pawl seat 80 at the end of the clamping beam 20. Since the clamping beam 20 is horizontally installed between the two end plates 30 and the length of the clamping beam 20 is also adapted to the distance between the two end plates 30 of the dumper, after the step of positioning the clamping beam 20, the position of the clamping beam 20 has been basically determined. In the subsequent fine alignment step of the clamping beam 20, only the positions at the ends of the clamping beam 20 need to be finely adjusted to further make the positions of the two pawl seats 80 at both ends of the clamping beam 20 meet the installation requirements. As Figure 5 shown, the pawl positioning plate 5 is in contact with the side of the pawl seat 80, and the template shaft holes 51 on the pawl positioning plate 5 are aligned with the two mounting shaft holes 801 on the pawl seat 80. Among them, the pawl seat 80 includes two parallel mounting plates, and the mounting shaft holes 801 penetrate through the two parallel mounting plates at the same time. The pawl positioning plate 5 is in contact with the side of the pawl seat 80, that is, the pawl positioning plate 5 is closely attached to the mounting plate in the pawl seat 80.

[0089] The connecting shaft 6 is a hollow straight tubular structure. The length of the connecting shaft 6 is set according to the installation requirements of the pawl seat at the end of the clamping beam. One end of the connecting shaft 6 is matched with the clamping arm pin shaft 60, and the other end of the connecting shaft 6 is matched with the second positioning shaft sleeve 3;

[0090] In the step S15, installing the auxiliary adjustment tooling on any one of the clamping arms 10 through the connecting shaft 6 includes the following steps:

[0091] Strike the clamping arm pin shaft 60 of the corresponding clamping arm 10 to expose one end of the proximal disk 30 of the clamping arm pin shaft 60 outside the corresponding clamping arm 10. Sleeve one end of the connecting shaft 6 on one end of the proximal disk 30 of the clamping arm pin shaft 60 of the corresponding clamping arm 10, and sleeve the second positioning bushing 3 on the auxiliary adjustment tooling on the other end of the connecting shaft 6.

[0092] In the fine alignment step of the clamping beam 20, the length of the connecting shaft 6 is set according to the assembly requirements of the clamping beam 20 and the pawl seat 80. After adjusting the clamping beam 20 so that the pawl positioning plate 5 is in contact with the pawl seat 80 provided at the end of the clamping beam 20, the distance between the pawl seat 80 and the end disk 30 can meet the assembly requirements. Furthermore, after installing the pawl on the pawl seat 80, the pawl can be in good meshing with the ratchet tooth block 90 on the end disk 30. At the same time, since one end of the connecting shaft 6 is sleeved on the clamping arm pin shaft 60 of the corresponding clamping arm 10 and the second positioning bushing 3 on the auxiliary adjustment tooling is sleeved on the other end of the connecting shaft 6, after installing the auxiliary adjustment tooling on any one of the clamping arms 10 through the connecting shaft 6, the auxiliary adjustment tooling can only rotate around the clamping arm pin shaft 60 of the corresponding clamping arm 10, and the plane where the pawl positioning plate 5 on the auxiliary adjustment tooling is located is fixed, which is convenient for accurately positioning and adjusting the position of the pawl seat 80.

[0093] In the step S1, connecting and fixing the bottom of each clamping arm 10 to the clamping beam 20 includes the following steps:

[0094] S17. Use a welding rod to firmly weld the bottom of the clamping arm 10 to the connecting flange.

[0095] S18. Use high-strength bolts to connect and fix the connecting flange at the bottom of each clamping arm 10 to the side of the clamping beam 20.

[0096] Before firmly welding the bottom of the clamping arm 10 to the flange and connecting and fixing the connecting flange at the bottom of the clamping arm 10 to the clamping beam 20 with high-strength bolts, it is necessary to reconfirm the coaxiality of the equalizing beam pin shafts 70 on multiple clamping arms 10, and the situation where the positioning edge of the auxiliary adjustment tooling fits with the clamping beam 20 when the auxiliary adjustment tooling is installed on each clamping arm 10. If the coaxiality of the equalizing beam pin shafts 70 on multiple clamping arms 10 meets the requirements, and the positioning edge can fit with the clamping beam 20 when the auxiliary adjustment tooling is installed on each clamping arm 10, it indicates that the positions of the clamping arm 10 and the clamping beam 20 after fine alignment meet the requirements. At this time, the bottom of the clamping arm 10 can be firmly welded to the connecting flange, and then corresponding bolt holes are machined on the side of the clamping beam 20, and the connecting flange at the bottom of each clamping arm 10 is connected and fixed to the side of the clamping beam 20 with high-strength bolts. If the positions of the clamping arm 10 and the clamping beam 20 do not meet the requirements after fine alignment, it is necessary to return to step S1 to reposition the clamping beam 20;

[0097] When confirming the coaxiality of the equalizing beam pin shafts 70 on multiple clamping arms 10, measure again the height of the equalizing beam pin shaft 70 on each clamping arm 10 from the track surface. If the error in the height of the equalizing beam pin shaft 70 on each clamping arm 10 from the track surface is within 5 mm, it is determined that the coaxiality of the equalizing beam pin shafts 70 on multiple clamping arms 10 meets the requirements.

[0098] After connecting and fixing the bottom of each clamping arm 10 to the clamping beam 20, push the clamping arm pin shaft 60 and the equalizing beam pin shaft 70 on each clamping arm 10 into the corresponding pin holes on the clamping arm 10, and install the shaft end baffles and screws at the clamping arm pin shaft 60 and the equalizing beam pin shaft 7 on each clamping arm 10.

[0099] As Figure 10 shown, after connecting and fixing the connecting flange at the bottom of each clamping arm 10 to the side of the clamping beam 20 with high-strength bolts, adjust the equalizing beam spring 501 on the car clamping mechanism 50 so that the relative height of the car clamping plate 502 at the bottom of each car clamping mechanism 50 from the platform track surface is the same, so that during the car tipping process of the car dumper, the car clamping plates at the bottom of each car clamping mechanism 50 can contact the top of the gondola car simultaneously.

[0100] In the said step S2, there are two methods to adjust the position of the ratchet block 90 according to the position of the pawl seat 80 fixedly arranged at the end of the clamping beam 20 and fix the adjusted ratchet block 90 on the end disc 30. The first method includes the following steps:

[0101] S211. Obtain two pawl positioning plates 5, mark the symmetry axes of the two template shaft holes 51 on the pawl positioning plates 5, and install the two pawl positioning plates 5 on the two pawl seats 80 located at both ends of the clamping beam 20 respectively;

[0102] The installation of the pawl positioning plate 5 on the pawl seat 80 specifically includes:

[0103] As Figure 7 shown, obtain the pawl connecting shaft 802, and make the pawl connecting shaft 802 pass through the template shaft hole 51 and the corresponding mounting shaft hole 801 at the same time. Connect the pawl positioning plate 5 and the pawl seat 80 through the pawl connecting shaft 802. The pawl connecting shaft 802 is a component used to hinge the pawl on the pawl seat 80 when installing the pawl.

[0104] S212. Adjust the position of the pawl positioning plate 5 so that the two template shaft holes 51 on the pawl positioning plate 5 are aligned with the two mounting shaft holes 801 on the corresponding pawl seat 80;

[0105] As Figure 7 shown, in the step S212, the adjustment of the position of the pawl positioning plate 5 so that the two template shaft holes 51 on the pawl positioning plate 5 are aligned with the two mounting shaft holes 801 on the corresponding pawl seat 80 specifically includes:

[0106] Mark the symmetry axes of the two template shaft holes 51 on the pawl positioning plate 5, and mark the symmetry axes of the two mounting shaft holes 801 on the corresponding pawl seat 80. Adjust the position of the pawl positioning plate 5 so that the symmetry axes of the two template shaft holes 51 coincide with the symmetry axes of the two mounting shaft holes 801. Among them, the coincidence of the symmetry axes of the two template shaft holes 51 and the symmetry axes of the two mounting shaft holes 801 means that the distance between the top of the symmetry axis of the two template shaft holes 51 on the pawl positioning plate 5 and the symmetry axis of the two mounting shaft holes 801 is not greater than 1.5 mm.

[0107] S213. Spot-weld the pawl positioning plate 5 to the pawl seat 80 or the clamping beam 20;

[0108] S214. Place a ratchet block 90 in each ratchet tooth installation area on the two end plates 30, and mark the symmetry axis of the ratchet block 90 on the ratchet block 90 placed on the end plate;

[0109] S215. Rotate the end plate 30 and adjust the position of the ratchet block 90 placed on the end plate so that the symmetry axes of the two ratchet blocks 90 can be aligned with the symmetry axes of the two template shaft holes 51 on the corresponding pawl positioning plate 5, and at the same time make the ratchet teeth at the top of the two ratchet blocks 90 closely adhere to the positioning arc edge 52 at the bottom of the corresponding pawl positioning plate 5;

[0110] As Figure 8As shown, the symmetry axis of the ratchet block 90 coincides with the symmetry axes of the two template shaft holes 51 on the corresponding pawl positioning plate 5. The coincidence of the symmetry axis of the ratchet block 90 with the symmetry axes of the two template shaft holes 51 on the corresponding pawl positioning plate 5 means that the deviation distance between the top of the symmetry axis of the ratchet block 90 and the bottom of the symmetry axes of the two template shaft holes 51 on the corresponding pawl positioning plate 5 is not greater than 1.5 mm. Ensuring that the symmetry axes of the ratchet blocks 90 located on the two end discs 30 can coincide with the symmetry axes of the two template shaft holes 51 on the corresponding pawl positioning plates 5 respectively can enable the pawls at both ends of the car clamping beam 20 to engage with the ratchet blocks 90 on the two end discs 30 simultaneously, ensuring the normal operation of the dumper.

[0111] After adjusting the position of the ratchet block 90 placed on the end disc, the symmetry axes of the template shaft holes 51 on the two pawl positioning plates 5 are respectively aligned with the same positions on the two ratchet blocks 90. For example, after adjusting the position of the ratchet block 90 placed on the end disc, if the symmetry axis of the template shaft hole 51 on one pawl positioning plate 5 is aligned with the sixth tooth on the corresponding ratchet block 90, then the symmetry axis of the template shaft hole 51 on the other pawl positioning plate 5 should also be aligned with the sixth tooth on the corresponding other ratchet block 90.

[0112] S216. Keep the position of the ratchet block 90 unchanged, and fix the ratchet block 90 after adjusting its position on the end disc 30 through the connecting bolts;

[0113] Before adjusting the position of the ratchet block 90, pre-weld and block the original bolt holes on the end disc 30 for installing the ratchet block 90. When fixing the ratchet block 90 on the end disc 30, set the bolt holes on the end disc 30 immediately according to the adjusted position of the ratchet block 90, and then install and fix the ratchet block 90 on the end disc 30 through the connecting bolts;

[0114] S217. Repeat steps S214 - S216 until all the ratchet blocks 90 are fixed on the end disc 30, and the ratchet blocks 90 located on the same end disc 30 can be connected into a continuous arc-shaped ratchet rack.

[0115] After all the ratchet blocks 90 are fixed on the end disc 30, the installation of the ratchet blocks 90 is completed. Subsequently, remove the pawl positioning plate 5 from the pawl seat 80, and install the pawl and the cam on the pawl seat 80. The installed pawl, cam and ratchet block 90 cooperate with each other to realize the locking and unlocking between the end disc 30 and the car clamping beam 20.

[0116] After the side-tilting dumper is adjusted, the clearance between the ratchet blocks 90 on the two end discs 30 and the pawls should not be greater than 3 mm, and the two pawls installed at both ends of the car clamping beam 20 can simultaneously engage with the ratchets on the ratchet blocks 90 installed on the two end discs 30.

[0117] In the step S2, the second method for adjusting the position of the ratchet block 90 according to the position of the ratchet seat 80 fixedly arranged at the end of the car clamping beam 20 and fixing the ratchet block 90 after the position adjustment on the end plate 30 includes the following steps:

[0118] S221. Before disassembling the side-tilting dumper, mark the running track of the car clamping beam 20 when the dumper is running on the two end plates 30 in advance, and record the position of the tooth top of the key tooth on each ratchet block 90 at the same time;

[0119] In the step S221, marking the running track of the car clamping beam 20 when the dumper is running on the end plate 30 specifically includes: before disassembling the car clamping beam 20 due to maintenance or transformation, remove the installed ratchet and ratchet block 90, test-run the dumper without a car and mark the running track of the car clamping beam 20 during the test run on the end plate 30, and the running track of the car clamping beam 20 when the dumper is running can be obtained.

[0120] S222. Install a ratchet on each of the ratchet seats 80 at both ends of the car clamping beam 20.

[0121] S223. Place the ratchet block 90 in the ratchet installation area on the two end plates 30, and adjust the position of the ratchet block 90 according to the running track of the car clamping beam 20 when the dumper is running, so that the center of the circle corresponding to the arc where the tooth top of the adjusted ratchet block 90 is located coincides with the center of the circle corresponding to the running track of the car clamping beam 20 during the test run, and the position of the tooth top of the key tooth on each ratchet block 90 is the same as that before disassembly; the key tooth can be any ratchet on the ratchet block 90. By recording the key tooth, it is ensured that the position of each ratchet block 90 after adjustment is the same as that before disassembling the side-tilting dumper, and at the same time, it can also ensure that the distance between the bottom of the ratchet seat 80 and the tooth top of the ratchet on the ratchet block 90 meets the installation requirements.

[0122] As Figure 9 shown, according to the dimensions of the ratchet seat 80 and the ratchet, when adjusting the position of the ratchet block 90, make the distance between the bottom of the ratchet seat 80 and the tooth top of the ratchet on the ratchet block 90 between 48 mm and 50 mm. Adjust the distance between the bottom of the ratchet seat 80 and the tooth top of the ratchet on the ratchet block 90 according to the dimensions of the ratchet seat 80 and the ratchet and the position of the mounting shaft hole 801 on the ratchet seat 80, so that when the ratchet meshes with any one of the ratchet blocks 90, the distance between the tip of the ratchet and the tooth root of the meshed ratchet is 1-2 mm, ensuring good meshing between the ratchet and the ratchet on the ratchet block 90.

[0123] S224. Keep the position of the ratchet block 90 unchanged, and fix the ratchet block 90 after the position adjustment on the end plate 30 through the connecting bolts.

[0124] While marking the running track of the clamping beam 20 during the operation of the dumper on the end plate 30, the position of the arc where the tooth top of the original ratchet block 90 is located can be marked on the end plate 30. After installing one ratchet block 90 and the pawl, compare the position of the arc where the tooth top of the installed ratchet block 90 is located with the marked position of the arc where the tooth top is located to minimize the installation error as much as possible. After installing multiple ratchet blocks 90, the positioning arc edge 52 on the pawl positioning plate 5 can be used to detect whether the tooth tops of two adjacent ratchet blocks 90 can simultaneously press against the positioning arc edge 52 on the pawl positioning plate 5, so as to ensure that the tooth tops of multiple ratchet blocks 90 are all located on the same arc.

[0125] When all the ratchet blocks 90 are fixed on the end plate 30, the installation of the ratchet blocks 90 is completed. Subsequently, install the pawl and the cam on the pawl seat 80 again. The installed pawl, cam and ratchet block 90 cooperate with each other to achieve the locking and unlocking between the end plate 30 and the clamping beam 20.

[0126] The principle of the present invention is described as follows:

[0127] In a side-tilting dumper, a pawl seat 80 for installing a pawl and a cam is provided at each end of the clamping beam 20. Each pawl seat 80 is provided with two mounting shaft holes 801 for installing the pawl and the cam. After adjustment, install the pawl and the cam on the pawl seat 80. The pawl and the cam installed on the pawl seat 80 cooperate with the ratchet block 90 installed on the end plate 30. When the pawl is engaged with the ratchet on the ratchet block 90, the end plate 30 and the clamping beam 20 are fixed by the ratchet block 90 and the pawl, and the end plate 30 and the clamping beam 20 can rotate synchronously with the pin shaft 60 of the clamping arm as the rotation center; when the pawl disengages from the ratchet on the ratchet block 90, the end plate 30 is separated from the clamping beam 20, and the end plate 30 and the clamping beam 20 can rotate out of sync; the ratchet block 90 of the side-tilting dumper is installed on the end plate, and the ratchet block 90 is an arc-shaped ratchet block. Multiple ratchet blocks 90 are spliced into an arc-shaped ratchet rack, and the arc-shaped ratchet rack cooperates with the pawl rotating with the clamping beam 20.

[0128] When overhauling or modifying a car dumper, it is often necessary to disassemble the clamping arm 10 on the car dumper. After modifying the clamping arm 10, the modified clamping arm 10 is reinstalled on the car dumper. In this process, the clamping arm 10 needs to be disassembled from the clamping beam 20 and removed from the car dumper. When reinstalling the clamping arm 10, the clamping arm 10 needs to be hinged to the main beam 40 through the clamping arm pin shaft 60 first, and then the clamping beam 20 is installed. Since it is easy to have installation errors after reinstalling the clamping arm 10 and the clamping beam 20, which may cause the postures of multiple clamping arms 10 connected to the clamping beam 20 to be difficult to be consistent or the pawls installed at the end of the clamping beam 20 to be unable to cooperate with the ratchet teeth on the end disc 30 of the car dumper. Therefore, after the modified clamping arm 10 is hinged to the main beam 40 through the clamping arm pin shaft 60, it is necessary to adjust the positions of multiple components such as the clamping arms 10, the clamping beam 20, and the ratchet blocks 90, and install the components together according to the adjusted positions. This method can ensure the installation accuracy when reinstalling the clamping arm 10, the clamping beam 20, and the ratchet block 90 on the car dumper after disassembling the clamping arm 10 due to modification, so that the postures of multiple clamping arms 10 can be consistent after reinstallation, and the pawls at the end of the clamping beam 20 can cooperate with the ratchet teeth on the end disc 30.

[0129] Embodiment 1:

[0130] An installation method for a side-tilting car dumper, the side-tilting car dumper includes: a clamping arm 10, a clamping beam 20, and an end disc 30.
