[0001] This application relates to the technical field of maintenance equipment for the main reducer of a vibratory source, and more specifically, to a rapid maintenance device for the main reducer of a vibratory source. Background Art

[0002] A vibratory source is a safe, environmentally friendly, efficient, and low-cost signal source in seismic exploration and is gradually widely adopted. With the increase in exploration intensity, the construction area has expanded to complex terrains such as saline-alkali land, deserts, farmland with multiple ditches, or mountainous areas. Previously, complex terrains were repaired with bulldozers to ensure the passage of the vibratory source, but now, due to environmental protection considerations, bulldozers are no longer used. Therefore, the chassis of the vibratory source conducts construction on rough roads in complex terrains. However, due to the lack of a traditional automotive shock-absorbing structure, the load on the drive axle increases, resulting in an increase in the failure rate.

[0003] When the drive axle is returned to the factory for repair, due to the lack of cooperation of special tooling, when the existing main reducer of the drive axle is disassembled for repair, it is necessary to use a crane in cooperation with sleepers for fixing and disassembly. The repair efficiency is low, and there are serious safety hazards for personnel during the repair process. Summary of the Invention

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0032] In the related art, after the drive axle is disassembled and separated, the disassembled main reducer is placed on the sleepers. During maintenance and adjustment, the main reducer can be rotated and the angle can be changed for maintenance according to different maintenance parts or other situations. This process is very time-consuming and labor-intensive and has great safety hazards.

[0033] Example

[0034] like Figures 1 to 4 As shown, a quick maintenance device for a vibrator main reducer comprises:

[0035] Rotating device and half-axle housing support stool, the rotating device includes a base frame 100, and a first support frame 200 and a second support frame 300 are assembled on one side of the base frame 100.

[0036] The base frame 100 serves as a bearing base for bearing the first support frame 200 and the second support frame 300. In order to reduce the weight of the device and save costs, the base frame 100 is integrally composed of a frame and reinforcing bars arranged staggeredly within the frame, thereby forming a stable frame structure with less material used.

[0037] Furthermore, in order to facilitate the movement of the rotating device, universal wheels 101 are provided at the lower end of the base frame 100.

[0038] The first support frame 200 and the second support frame 300 are arranged on the same side of the base frame 100, that is, the side of the base frame 100 away from the ground. And the overall structures of the first support frame 200 and the second support frame 300 are similar to that of the base frame 100, both being hollow in the middle and assembled with staggered reinforcing bars. Such an arrangement can also reduce the weight of the device and save costs.

[0039] A first support mechanism is provided at one end of the first support frame 200 away from the base frame 100. A second support mechanism is provided at one end of the second support frame 300 away from the base frame 100. The first support mechanism and the second support mechanism are used to bear both ends of the controllable vibration source main reducer housing.

[0040] Specifically, the first support frame 200 and the second support frame 300 are arranged far away from each other on the base frame 100. And the distance between the first support frame 200 and the second support frame 300 corresponds to the controllable vibration source main reducer housing, so that both ends of the controllable vibration source main reducer housing along the driving shaft direction of the driving gear can be respectively placed on the first support mechanism and the second support mechanism, thereby supporting the controllable vibration source main reducer housing.

[0041] Furthermore, in order to stably bear the controllable vibration source main reducer, both the first support mechanism and the second support mechanism are provided with bearing grooves 500. The bearing grooves 500 are used to place the controllable vibration source main reducer housing, and the bearing grooves 500 can play a limiting role, so that the controllable vibration source main reducer does not slide on the first support mechanism and the second support mechanism. And the two bearing grooves 500 are at the same horizontal height, ensuring that the controllable vibration source main reducer is placed stably horizontally in the two bearing grooves 500.

[0042] Specifically, the first support mechanism includes a first support block 201, and the bearing groove 500 on the first support mechanism runs through the center of the first support block 201, and the bearing groove 500 on the first support mechanism is cylindrical. The cylindrical bearing groove 500 matches the end of the controllable vibrator main reducer housing, and while supporting the controllable vibrator main reducer, it will not affect the rotation of the controllable vibrator main reducer.

[0043] When placing the controllable seismic source main reducer housing inside the bearing groove 500, align one end of the controllable seismic source main reducer housing with the bearing groove 500 on the first support block 201 at the same horizontal height. Then move the entire maintenance device so that one end of the controllable seismic source main reducer housing enters the bearing groove 500 on the first support block 201. While one end of the controllable seismic source main reducer housing is supported by the first support block 201, it is also limited by the first support block 201. In this way, when rotating, the controllable seismic source main reducer will not be separated from the bearing groove 500 on the first support block 201, ensuring the stability of the controllable seismic source main reducer during rotation and reducing safety hazards.

[0044] Furthermore, in order to facilitate the rotation of the vibrator main reducer, the first support block 201 is equipped with a plurality of pulleys 202 along the circumference of the bearing slot 500. When in use, butter may be applied to the pulleys 202 to reduce the friction of rotation.

[0045] The second support mechanism includes a second support block 301, and the bearing groove 500 on the second support mechanism is opened on the second support block 301, and the bearing groove 500 on the second support mechanism is set in a semi-cylindrical shape on the second support block 301. The bearing groove 500 on the second support mechanism is set in a semi-cylindrical shape, and can also bear the end of the controllable source main reducer housing without affecting the rotation of the controllable source main reducer. In this way, the entire controllable source main reducer can rotate around the driving shaft of the driving gear under the support of the first support mechanism and the second support mechanism, so that the interface of the controllable source main reducer connected to the half-shaft can be changed in angle and direction as the rotation occurs, thereby facilitating maintenance and adjustment by maintenance personnel.

[0046] When placing both ends of the controllable vibration source main reducer housing into the two bearing grooves 500, first adjust the height of the controllable vibration source main reducer so that one end of the controllable vibration source main reducer housing is placed into the bearing groove 500 on the second support mechanism, and the other end of the controllable vibration source main reducer housing is aligned with the bearing groove 500 on the first support block 201. Then move the rotating device (i.e., move the base frame 100) so that the first support frame 200 moves towards the controllable vibration source main reducer housing, thereby enabling the other end of the controllable vibration source main reducer housing to enter the interior of the bearing groove 500 on the first support block 201, completing the placement of the controllable vibration source main reducer.

[0047] Furthermore, in order to prevent the end of the controllable vibration source main reducer housing that is already on the second support mechanism from detaching from the bearing groove 500 at the second support mechanism when moving the rotating device to enable the other end of the controllable vibration source main reducer housing to enter the interior of the bearing groove 500 on the first support block 201. A sliding groove 303 is provided between the base frame 100 and the second support frame 300. The sliding groove 303 is arranged along the direction from the first support frame 200 to the second support frame 300, and the sliding groove 303 is fixedly connected to the base frame 100. One end of the second support frame 300 close to the base frame 100 is slidably assembled inside the sliding groove 303.

[0048] When moving the rotating device to enable the other end of the controllable vibration source main reducer housing to enter the interior of the bearing groove 500 on the first support block 201. The second support frame 300 can be simultaneously moved to slide inside the sliding groove 303 so that the relative position between the second support mechanism on the second support frame 300 and the controllable vibration source main reducer housing does not change. That is, with the controllable vibration source main reducer housing as a reference, the position of the second support frame 300 remains unchanged. During the process of moving the maintenance device, only components such as the base frame 100, the first support frame 200, and the first support mechanism are moved.

[0049] Furthermore, in order to rotate the controllable vibration source main reducer and lock the controllable vibration source main reducer at a desired angle, an installation plate 302 is provided at the second support frame 300 close to the second support block 301. The installation plate 302 is used to install a speed reducer.

[0050] The output shaft of the speed reducer can be connected to the input flange of the controllable vibration source main reducer. When the input flange is connected to the housing of the controllable vibration source main reducer, rotate the output shaft of the speed reducer. The output shaft of the speed reducer drives the input flange to rotate, and the rotation of the input flange drives the controllable vibration source main reducer to rotate, realizing the angle adjustment of the controllable vibration source main reducer. Moreover, by utilizing the self-locking characteristic of the worm and worm gear of the speed reducer, the rotating device can achieve staying at any angle during the maintenance process of the main reducer, facilitating the installation and adjustment of the driving gear and the driven gear of the reducer after maintenance. Thus, the controllable vibration source main reducer can be maintained at any angle, greatly facilitating the maintenance operation.

[0051] When it is necessary to adjust the position between the driving gear and the driven gear, first connect the output shaft of the speed reducer to the input flange, but remove the connection between the input flange and the housing of the controllable vibration source main reducer. In this way, the second support frame 300 can be slid, and the speed reducer will move along with the second support frame 300, so as to separately pull or rotate the input flange, as well as the drive shaft and the driving gear of the input flange, to adjust between the driving gear and the driven gear, ensure the flank clearance between the driving gear and the driven gear, or check and adjust the meshing condition between the driving gear and the driven gear, and ensure the correct size and position of the meshing impression.

[0052] As Figure 5 and 6 As shown in the figure, further, before disassembling the controllable vibration source main reducer from the drive axle (the drive axle includes components such as the controllable vibration source main reducer and the half axle housing), to facilitate the placement and disassembly of the drive axle, a half axle housing support bench is also provided. The half axle housing support bench includes a support bench body 400, and two rows of positioning holes 401 are provided on the bench surface of the support bench body 400, and the positioning holes 401 correspond to the mounting holes of the half axle housing one by one.

[0053] During maintenance, first prepare two half-axle housing support stools, and place the two half-axle housing support stools respectively corresponding to the half-axle housings on both sides of the controllable source main reducer. When placing, place the two half-axle housings of the drive axle on the two half-axle housing support stools correspondingly, and make the mounting holes of the half-axle housing and the positioning holes 401 of the half-axle housing support stools correspond one by one. Then use bolts to penetrate the mounting holes of the correspondingly corresponding half-axle housing and the positioning holes 401 of the half-axle housing support stools to fix the two, so that the two half-axle housing support stools support the entire drive axle. At this time, the controllable source main reducer is located between the two half-axle housing supports. Then place the rotating device under the controllable source main reducer so that the controllable source main reducer can be supported.

[0054] Further, in the state where the controllable source main reducer is located between the two half-axle housing supports, in order to make the controllable source main reducer reach a suitable height and be placed on the rotating device. A connecting plate 402 is provided at the end of the stool leg of the support stool body 400, and a lifter 403 (the lifter 403 is a prior art, only the top plate part showing the connection between the lifter 403 and the connecting plate 402 is shown in Figure 5 and is not shown and described in detail). In this way, the half-axle housing support stool can be lifted by the lifter 403 to lift the entire drive axle, and there is no need to lift the drive axle or the controllable source main reducer to adjust the height.

[0055] Further, in order to enhance the stress capacity of the half-axle housing support stool, reinforcing ribs 404 are provided between the stool legs of the support stool body 400 and the stool surface of the support stool body 400, and the reinforcing ribs 404 are also provided between the stool legs of the support stool body 400 and the connecting plate 402.

[0056] Specifically, when repairing the controllable source main reducer. First prepare two half-axle housing support stools, and place the two half-axle housing support stools respectively corresponding to the half-axle housings on both sides of the controllable source main reducer. Then lift the drive axle, place the two half-axle housings of the drive axle on the two half-axle housing support stools correspondingly, and make the mounting holes of the half-axle housing and the positioning holes 401 of the half-axle housing support stools correspond one by one. Then use bolts to penetrate the mounting holes of the correspondingly corresponding half-axle housing and the positioning holes 401 of the half-axle housing support stools to fix the two, so that the two half-axle housing support stools support the entire drive axle. At this time, the controllable source main reducer is located between the two half-axle housing supports.

[0057] After the drive axle is fixed on the two half axle housing support stools, start the lift 403 under the half axle housing support stools, so that the lift 403 drives the drive axle to a proper height (a proper height higher than that of the rotating device), and move the rotating device to the corresponding position under the controllable source main reducer. Then, slowly lower the height of the drive axle through the lift 403, so that the controllable source main reducer slowly approaches the rotating device until one end of the controllable source main reducer housing along the driving shaft direction of the driving gear is placed in the bearing groove 500 on the second support mechanism. Close the lift 403 to stop the drive axle from descending.

[0058] Then, move the entire maintenance device (move the base frame 100 and the first support frame 200) so that the other end of the controllable source main reducer housing along the driving shaft direction of the driving gear enters the bearing groove 500 on the first support block 201. At the same time, when moving the base frame 100 and the first support frame 200, also move the second support frame 300 to slide in the sliding groove 303, so that the relative position between the second support mechanism on the second support frame 300 and the controllable source main reducer housing does not change. That is, taking the controllable source main reducer housing as a reference, the position of the second support frame 300 remains unchanged. During the process of moving the maintenance device, only components such as the base frame 100, the first support frame 200 and the first support mechanism are moved. At this time, the controllable source main reducer is placed on the rotating device.

[0059] Then, disassemble and separate the controllable source main reducer and the half axle housing, and move the half axle housing away, so that the controllable source main reducer is disassembled from the drive axle and is supported by the rotating device.

[0060] Then, the main reducer of the vibrator can be repaired. During specific repair, at the horizontal position (i.e., the initial position after disassembly), each component of the main reducer of the vibrator can be disassembled from both sides where the main reducer of the vibrator is connected to the half axle housing. At the same time, the pre-tightening force of the bearing of the driving gear of the main reducer can be adjusted. The output shaft of the reducer can also be connected to the input flange, and the connection between the input flange and the housing of the main reducer of the vibrator can be removed. In this way, the second support frame 300 can be slid, and the reducer will move along with the second support frame 300, so as to separately pull or rotate the input flange (rotating the reducer to rotate the input flange), as well as the drive shaft and the driving gear of the driving gear connected to the input flange, and adjust between the driving gear and the driven gear to ensure the tooth side clearance between the driving gear and the driven gear, or check and adjust the meshing condition between the driving gear and the driven gear to ensure the correct size and position of the meshing impression.

[0061] When it is necessary to rotate the entire main reducer of the vibrator, the output shaft of the reducer is connected to the input flange of the main reducer of the vibrator. When the input flange is connected to the housing of the main reducer of the vibrator, rotate the output shaft of the reducer. The output shaft of the reducer drives the input flange to rotate, and the rotation of the input flange drives the main reducer of the vibrator to rotate, realizing the angle adjustment of the main reducer of the vibrator. And by using the self-locking characteristic of the worm and worm gear of the reducer, the rotating device can stay at any angle during the repair process of the main reducer, which is convenient for the installation and adjustment of the driving gear and the driven gear of the reducer after repair. Thus, the repair operation of the main reducer of the vibrator can be carried out at any angle. For example, when rotating 90° clockwise from the initial position, the two side ports where the main reducer of the vibrator is connected to the half axle housing are vertically up and down. In this state, the clearance or pre-tightening force of the bearing of the driven gear can be adjusted from one of the ports. After continuing to rotate 180° clockwise, the clearance or pre-tightening force of the bearing of the driven gear can be adjusted at the other port. This greatly facilitates the repair operation.

[0062] In this application, by using a set of tools, the separation between the half axle housing of the drive axle and the main reducer of the vibrator can be quickly realized. The rotating device can support the main reducer of the vibrator through the first support mechanism and the second support mechanism, and rotate and lock the main reducer of the vibrator by setting a reducer, so as to realize the rotational positioning of the main reducer, which is convenient for the repair and adjustment of the main reducer, and solves the problems of potential safety hazards or time-consuming and laborious work when rotating the main reducer of the vibrator in the prior art.
