[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 technology, the articulated system of the controllable vibrator is composed of radial spherical bearings, angular contact spherical bearings, articulated pins, retaining rings, flanges, conical retaining sleeves and other components. Each component works in extremely harsh working conditions, and is subjected to huge and unbalanced tension, torsional force and high-frequency vibration force, etc. In addition, the amount of seismic exploration projects is large, and the controllable vibrator has been running at full load for a long time, resulting in a significant increase in the frequency of damage to the articulated system and a significant increase in the degree of damage. The articulated maintenance of the controllable vibrator is as high as about 60 times per year.

[0033] During the current hinge maintenance process, when installing the hinge pin, a sledgehammer is usually used to knock the hinge pin into the pin installation hole, which takes a long time to install and affects production efficiency.

[0034] In view of this, an embodiment of the present application proposes a controllable seismic source hinge pin installation tool.

[0035] See also Figure 1 and Figure 2, a controllable vibration source articulated pin installation tool, which is applied to the installation of the articulated pin 3 on the vibration source frame 1, and includes:

[0036] A pressure plate 4, which is detachably installed on the vibration source frame 1. A pin installation hole 2 is provided on the vibration source frame 1. A through hole is provided at the center of the pressure plate 4 corresponding to the position of the pin installation hole 2. The articulated pin 3 is placed in the through hole and is coaxial with the pin installation hole 2;

[0037] A jacking device 5 is arranged on the side of the pressure plate 4 away from the pin installation hole 2. The first end of the jacking device 5 is coaxial with and abuts against the articulated pin 3. The jacking device 5 is used to push the articulated pin 3 to move axially so that the articulated pin 3 is pressed into the pin installation hole 2;

[0038] A support frame 6 is arranged on the pressure plate 4 and abuts against the second end of the jacking device 5 for fixing the jacking device 5.

[0039] Specifically, as Figure 1 shown, two opposite ear plates are provided at the position on the vibration source frame 1 for installing the articulated pin 3. The pin installation hole 2 is provided on the ear plate. The articulated pin 3 needs to be installed in the pin installation hole 2 in an interference fit manner. The pressure plate 4 is detachably installed on the upper ear plate. A through hole is provided at the position on the pressure plate 4 directly opposite to the pin installation hole 2. The diameter of the through hole is slightly larger than the diameter of the articulated pin 3, which can provide space for placing the articulated pin 3. When installing the articulated pin 3, the articulated pin 3 is placed in the through hole. The lower end of the articulated pin 3 contacts the pin installation hole 2, and the articulated pin 3 is coaxial with the pin installation hole 2. The jacking device 5 and the support frame 6 are arranged on the upper end of the pressure plate 4. The jacking device 5 is arranged coaxially with the articulated pin 3. The support frame 6 is used to press tightly on the upper end of the jacking device 5 so that the lower end of the jacking device 5 abuts tightly against the articulated pin 3. The jacking device 5 is used to apply an axial jacking force to the articulated pin 3 so that the articulated pin 3 can move downward axially and gradually be pressed into the pin installation hole 2 to achieve an interference fit with the pin installation hole 2.

[0040] Through the above settings, the jacking device 5 is used to push the articulated pin 3 to move axially so as to press the articulated pin 3 into the pin installation hole 2, replacing the traditional knocking installation method. It is easy and labor-saving, and at the same time shortens the installation time of the articulated pin 3 and improves the maintenance efficiency.

[0041] Further, the installation tool further includes a positioning block 7; the positioning block 7 is tightly abutted between the hinge pin 3 and the jacking device 5. A positioning groove 71 adapted to the hinge pin 3 is provided on the side of the positioning block 7 facing the hinge pin 3, and one end of the hinge pin 3 is located in the positioning groove 71; the outer diameter of the positioning block 7 is larger than the diameter of the pin installation hole 2.

[0042] See Figure 2 and Figure 3 , the installation tool further includes a positioning block 7. The positioning block 7 is arranged between the hinge pin 3 and the jacking device 5. When the support frame 6 is pressed against the upper end of the jacking device 5, the lower end of the jacking device 5 abuts tightly against the positioning block 7, and the positioning block 7 abuts tightly against the hinge pin 3. A positioning groove 71 is formed on the side of the positioning block 7 facing the hinge pin 3, and the inner diameter of the positioning groove 71 is adapted to the diameter of the top end of the hinge pin 3. During installation, the top end of the hinge pin 3 is exactly located in the positioning groove 71. The outer diameter of the positioning block 7 is larger than the diameter of the pin installation hole 2, and the positioning block 7 cannot enter the pin installation hole 2. When the jacking device 5 pushes the positioning block 7 and the hinge pin 3 to move synchronously, the hinge pin 3 gradually enters the pin installation hole 2, while the positioning block 7 always remains outside the pin installation hole 2 until the positioning block 7 abuts against the upper ear plate to form a limit, and the jacking device 5 can no longer continue to push the positioning block 7 and the hinge pin 3 to move. At this time, the installation is in place, and the part of the top end of the hinge pin 3 located in the positioning groove 71 is exactly clamped outside the pin installation hole 2. By providing the positioning block 7, the installation depth of the hinge pin 3 in the axial direction can be limited, avoiding excessive pushing and ensuring the accuracy of the installation position.

[0043] Further, the hinge pin 3 includes a main shaft portion 31 and a clamping portion 32. The clamping portion 32 is provided at one end of the main shaft portion 31, and the diameter of the clamping portion 32 is larger than that of the main shaft portion 31; the clamping portion 32 is located in the positioning groove 71, and the diameter of the positioning groove 71 is adapted to the diameter of the clamping portion 32, and the depth of the positioning groove 71 is adapted to the thickness of the clamping portion 32.

[0044] See Figure 3 and Figure 4, the articulated pin shaft 3 includes a main shaft portion 31 and a clamping portion 32. Among them, the diameter of the main shaft portion 31 is slightly larger than the diameter of the pin shaft mounting hole 2 to ensure an interference fit between the main shaft portion 31 and the pin shaft mounting hole 2 during installation; the clamping portion 32 is located at one end of the main shaft portion 31 and has a diameter larger than that of the main shaft portion 31. As the clamping structure at the top of the articulated pin shaft 3, it can be clamped outside the pin shaft mounting hole 2 after being installed in place. The clamping portion 32 is located in the positioning groove 71. The inner diameter of the positioning groove 71 is adapted to the diameter of the clamping portion 32, and the depth of the positioning groove 71 is adapted to the axial thickness of the clamping portion 32. In this way, during installation, the clamping portion 32 can just be placed in the positioning groove 71. Through the axial depth limit of the positioning block 7, it can be ensured that the clamping portion 32 is exactly clamped outside the pin shaft mounting hole 2 after being installed in place, without causing excessive pushing.

[0045] In practical applications, the inner diameter and depth of the positioning groove 71 can be flexibly set according to the different specifications and dimensions of the articulated pin shaft 3 to ensure that the positioning groove 71 can be adapted to the articulated pin shaft 3.

[0046] Optionally, the articulated pin shaft 3 further includes a guiding portion 33. The guiding portion 33 is provided at one end of the main shaft portion 31 away from the clamping portion 32, and the diameter of the guiding portion 33 gradually decreases from the end close to the main shaft portion 31 to the end away from the main shaft portion 31; the minimum diameter of the guiding portion 33 is smaller than the diameter of the pin shaft mounting hole 2, and the main shaft portion 31 has an interference fit with the pin shaft mounting hole 2.

[0047] Specifically, the articulated pin shaft 3 further includes a guiding portion 33. The guiding portion 33 is provided at one end of the main shaft portion 31 away from the clamping portion 32. The guiding portion 33 is a conical structure, and its diameter gradually decreases from the end close to the main shaft portion 31 to the end away from the main shaft portion 31. The maximum diameter of the guiding portion 33 is the same as the diameter of the main shaft portion 31, and the minimum diameter of the guiding portion 33 is smaller than the pin shaft mounting hole 2. When the articulated pin shaft 3 is placed into the through hole of the pressure plate 4, a part of the guiding portion 33 can enter the pin shaft mounting hole 2. When the lifting device 5 pushes the articulated pin shaft 3 to move axially into the pin shaft mounting hole 2, the inclined side wall surface of the guiding portion 33 can play a role of transitional guiding to ensure that the main shaft portion 31 of the articulated pin shaft 3 can be smoothly pressed into the pin shaft mounting hole 2.

[0048] Furthermore, the outer diameter of the positioning block 7 is adapted to the diameter of the through hole, and the positioning block 7 can slide axially relative to the pressure plate 4 in the through hole.

[0049] Specifically, during the installation process of the hinge pin 3, the lifting device 5 will push the positioning block 7 and the hinge pin 3 to move axially towards the direction close to the pin installation hole 2. Since the outer diameter of the positioning block 7 is adapted to the diameter of the through hole in the pressure plate 4, when the positioning block 7 enters the through hole of the pressure plate 4, the outer side wall of the positioning block 7 can generate axial relative sliding with the inner side wall of the pressure plate 4, thereby guiding the axial movement of the hinge pin 3, preventing the hinge pin 3 from shifting and skewing during the installation process, ensuring the axial transmission efficiency of the power, ensuring the coaxiality between the hinge pin 3 and the pin installation hole 2, and ensuring uniform force on the hinge pin 3 during the installation process.

[0050] Optionally, the support frame 6 includes: a support rod 61 disposed on the pressure plate 4 along the axial direction of the pressure plate 4; a pressing plate 62 passing through the support rod 61 and disposed at one end of the lifting device 5 away from the hinge pin 3; a locking member disposed on the side of the pressing plate 62 away from the pressure plate 4 and connected to the support rod 61, and the locking member is used to lock the axial position of the pressing plate 62 so that the pressing plate 62 presses the second end of the lifting device 5.

[0051] As Figure 2 shown, the support rod 61 is disposed along the axial direction of the pressure plate 4. The lower end of the support rod 61 is connected to the pressure

[0052] plate 4. The pressing plate 62 penetrates from the upper end of the support rod 61 and abuts against the upper end of the lifting device 5. The locking member is disposed at the upper end of the pressing plate 62 and connected to the upper end of the support rod 61 for fixing the axial height of the pressing plate 62, so that the pressing plate 62 can press against the upper end of the lifting device 5, and the lower end of the lifting device 5 can abut against the positioning block 7 and the hinge pin 3, ensuring that the upper end of the lifting device 5 can remain relatively fixed with the pressure plate 4 during the installation process and ensuring efficient power transmission.

[0053] Preferably, the support rod 61 is detachably connected to the pressure plate 4.

[0054] In this embodiment, the support rod 61 and the pressure plate 4 are detachably connected. When the installation tool is not in use, the support rod 61 and the pressure plate 4 can be disassembled and stored to reduce space occupation. Specifically, the support rod 61 is a screw rod, and a threaded hole is correspondingly opened on the pressure plate 4. The support rod 61 and the pressure plate 4 are connected by means of thread fitting. In some other embodiments, the support rod 61 and the pressure plate 4 can also be detachably connected by bolts or other fasteners.

[0055] Optionally, the support rod 61 is provided with an external thread, and the locking member includes a nut 63, and the nut 63 is in threaded cooperation with the support rod 61.

[0056] Specifically, in this embodiment, the support rod 61 is a screw rod with external threads provided on its outer periphery. Correspondingly, the locking member is a nut 63. By locking with the cooperation of the nut 63 and the screw rod, axial limitation of the pressure plate 62 can be achieved, enabling the pressure plate 62 to tightly press against the upper end of the jacking device 5.

[0057] Optionally, the number of the support rods 61 is set to two, and the two support rods 61 are symmetrically distributed on both sides of the jacking device 5.

[0058] As Figure 2 shown, in this embodiment, there are two support rods 61, and the two support rods 61 are symmetrically distributed on the left and right sides of the jacking device 5. Correspondingly, the pressure plate 62 adopts a rectangular block structure, and through holes adapted to the two support rods 61 are provided at corresponding positions on the pressure plate 62. The two support rods 61 are symmetrically distributed, which is beneficial to ensuring uniform force distribution of the structure and improving the installation stability of the jacking device 5.

[0059] In some other embodiments, the number of the support rods 61 can also be three, and the three support rods 61 can be distributed in a triangular shape; in some other embodiments, the number of the support rods 61 can also be more than three.

[0060] Optionally, a plurality of bolt holes are circumferentially and spacedly distributed along the pressure plate 4, and the pressure plate 4 and the vibration source vehicle frame 1 are connected by a plurality of bolts.

[0061] In this embodiment, a plurality of bolt holes are evenly and spacedly distributed in the circumferential direction of the pressure plate 4. The number and distribution positions of the bolt holes on the pressure plate 4 correspond to the bolt holes on the vibration source vehicle frame 1, and the pressure plate 4 and the vibration source vehicle frame 1 are connected by bolts. Through the above settings, the fixed points between the pressure plate 4 and the vibration source vehicle frame 1 are evenly distributed, which is beneficial to ensuring the reliability of the installation.

[0062] Optionally, in this embodiment, the jacking device 5 includes a jack, which has a solid and reliable structure, is light and portable, and can axially push the hinge pin 3 when installing the hinge pin 3, and easily press the hinge pin 3 into the pin installation hole 2.

[0063] The process of installing the hinge pin 3 using the installation tool provided in the embodiment of the present application is as follows:

[0064] First, fix the pressure plate 4 to the vibration source vehicle frame 1 by bolts, align the through hole of the pressure plate 4 with the pin installation hole 2 coaxially, and install the support rod 61 on the pressure plate 4;

[0065] Apply a small amount of butter to the hinge pin 3 for lubrication, place the hinge pin 3 into the through hole of the pressure plate 4, and make the guiding portion 33 at the lower end of the hinge pin 3 contact the pin installation hole 2 to keep the hinge pin 3 stable;

[0066] Place the positioning block 7 on the top of the hinge pin 3, so that the clamping portion 32 at the top of the hinge pin 3 is embedded in the positioning groove 71 of the positioning block 7;

[0067] Place the jack steadily on the mounting block, pass the pressing plate 62 through the support rod 61 and press it onto the jack, screw the nut 63 onto the support rod 61 to lock the pressing plate 62, so that the pressing plate 62 presses the jack tightly and the jack abuts against the mounting block;

[0068] Start the jack, and the jack slowly pushes the positioning block 7 and the hinge pin 3 to move axially, so that the hinge pin 3 is pressed into the hinge mounting hole;

[0069] When the positioning block 7 abuts against the outside of the pin mounting hole 2 and cannot move further, the hinge pin 3 is installed in place.

[0070] The controllable vibration source hinge pin installation tool provided by the embodiment of the present application has a simple structure and is convenient for disassembly and assembly. The jacking device 5 is used to push the hinge pin 3 to move axially, so as to press the hinge pin 3 into the pin mounting hole 2, ensuring the coaxiality of the hinge pin 3 and the pin mounting hole 2 during the installation process and the uniform force of the hinge pin 3 during the installation process. Compared with the traditional manual knocking method, it saves time and effort and effectively improves the maintenance and installation efficiency of the controllable vibration source hinge pin.
