[0024] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0025] In related technologies, with the large-scale application of controllable vibrators, the harsh terrain environment and high-intensity use have led to an increasing trend in the damage of the swing frame pins and bearings. A large number of vibrator swing frame pins are severely worn and need to be replaced and repaired.

[0026] The current maintenance and replacement of the swing frame pin requires the disassembly and installation of multiple hydraulic pipelines and the use of a crane to complete the lifting. The maintenance is intensive, time-consuming and inefficient.

[0027] In view of this, an embodiment of the present application provides a vibrator swing frame pin installation tool.

[0028] See also Figure 1 A vibrator swing frame pin installation tool is used to install a pin 2 on a vibrator swing frame beam 1. The swing frame beam 1 has a pin installation hole, and the pin 2 is placed on one side of the swing frame beam 1 corresponding to the pin installation hole. The installation tool includes:

[0029] The mounting shaft 3 is arranged on a side of the swing frame beam 1 away from the pin shaft 2, corresponding to the pin shaft mounting hole, one end of the mounting shaft 3 is detachably connected to the pin shaft 2, and the mounting shaft 3 is provided with an external thread;

[0030] An abutment member 4 is passed through the mounting shaft 3 , and a first end of the abutment member 4 is tightly abutted against the swing frame beam 1 ;

[0031] A nut 6 is provided at one end of the mounting shaft 3 away from the pin 2 and is threadedly engaged with the mounting shaft 3. The nut 6 can be tightly pressed against the second end of the abutment member 4 and rotated relative to the mounting shaft 3, so that the mounting shaft 3 moves axially and drives the pin 2 axially into the pin mounting hole;

[0032] The limiting member 7 is connected to the installation shaft 3 and is used to limit the installation shaft 3 from rotating in the circumferential direction.

[0033] For details, see Figure 1 A pin mounting hole is provided in the swing frame beam 1. The corresponding pin mounting hole for the pin 2 is located on the right side of the swing frame beam 1. The corresponding pin mounting hole for the installation tool is located on the left side of the swing frame beam 1, opposite the pin 2. The axis of the installation tool's mounting shaft 3, the stopper 7, the nut 6, and the axis of the pin 2 are all coaxial with the pin mounting hole.

[0034] The pin 2 includes a clamping section, a main shaft section and a threaded section which are connected in sequence, wherein the diameter of the main shaft section is slightly larger than the diameter of the pin mounting hole so as to achieve an interference fit with the pin mounting hole; the clamping section serves as the head of the pin 2, and its diameter is larger than the diameter of the main shaft section. After being installed in place, it can be clamped on the outside of the pin mounting hole; the threaded section serves as the tail end of the pin 2, and its diameter is smaller than the diameter of the main shaft section and the diameter of the pin mounting hole. During installation, it can be directly placed into the pin mounting hole from the right side of the swing frame beam 1, and will pass through the left side of the pin mounting hole after being installed, which is convenient for locking with the matching pin nut.

[0035] The diameter of the mounting shaft 3 is smaller than the diameter of the pin mounting hole, so the mounting shaft 3 can pass through the pin mounting hole from the left side of the swing frame beam 1 to connect with the tail end of the pin 2; the abutment 4 is provided on the mounting shaft 3, and the axial length of the abutment 4 is smaller than the length of the mounting shaft 3, so the two ends of the mounting shaft 3 can pass through the two ends of the abutment 4, see Figure 1 and Figure 3The right end of the mounting shaft 3 is used to connect with the tail end of the pin shaft 2, and the left end of the mounting shaft 3 passes through the left end of the abutment 4. The nut 6 is sleeved on the left end of the mounting shaft 3. The mounting shaft 3 is provided with an external thread. The nut 6 is threadedly matched with the mounting shaft 3. Since the circumferential size of the abutment 4 is larger than the size of the pin shaft mounting hole, when the nut 6 is pressed against the left end of the abutment 4, the right end of the abutment 4 can be pressed against the outside of the pin shaft mounting hole, that is, Figure 1 The left side of the swing frame beam 1 is shown. The limiting member 7 is connected to the end of the installation shaft 3 away from the pin 2 to limit the rotation of the installation shaft 3.

[0036] When the nut 6 is pressed against the abutment 4 and the rocking frame beam 1 and rotates, the axial position of the nut 6 is fixed, and since the limit member 7 limits the circumferential rotation of the mounting shaft 3, the rotational motion of the nut 6 can be converted into the axial linear motion of the mounting shaft 3 through the threaded cooperation between the nut 6 and the mounting shaft 3, thereby pulling the pin shaft 2 to continuously enter the pin shaft mounting hole along the axial direction, and finally realizing the interference installation of the pin shaft 2 in the pin shaft mounting hole.

[0037] Through the above arrangement, the pin shaft 2 can be quickly installed with simple operation and without the need for hoisting, thereby greatly improving the maintenance efficiency of the pin shaft 2.

[0038] Optionally, the limiting member 7 includes a crowbar, and a through hole is formed at one end of the installation shaft 3 away from the pin shaft 2, and one end of the crowbar is connected to the installation shaft 3 through the through hole.

[0039] In this embodiment, the stopper 7 comprises a crowbar, which is detachably connected to the mounting shaft 3. Specifically, a circular shaft segment is provided at the end of the mounting shaft 3 away from the connecting pin 2. The circular shaft segment is not threaded but has a through hole. One end of the crowbar can be inserted into the through hole to securely connect with the mounting shaft 3.

[0040] When using the installation tool to install the pin shaft 2, the operator holds the crowbar in one hand and uses a wrench or other tools to tighten the nut 6 in the other hand. The crowbar is used to keep the installation shaft 3 circumferentially fixed to prevent the installation shaft 3 from rotating with the nut 6. In this way, the rotational motion of the nut 6 can be converted into axial motion of the installation shaft 3, thereby achieving smooth installation of the pin shaft 2.

[0041] Optionally, the abutment 4 includes a cylinder 41 and a first pressure plate 42 and a second pressure plate 43 connected to the two ends of the cylinder 41; a hollow accommodating space is formed inside the cylinder 41, and the centers of the first pressure plate 42 and the second pressure plate 43 are each provided with a through hole for the installation shaft 3 to pass through; the first pressure plate 42 is tightly pressed against the swing frame beam 1, and the second pressure plate 43 is tightly pressed against the nut 6.

[0042] Specifically, the abutment member 4 comprises a cylinder 41, a first pressure plate 42, and a second pressure plate 43. The cylinder 41 is a hollow cylindrical structure, and its internal cavity provides a space for accommodating the mounting shaft 3. The first and second pressure plates 42, 43 are respectively disposed at opposite ends of the cylinder 41. To facilitate the passage of the mounting shaft 3, through-holes are formed in the first and second pressure plates 42, 43. During use, the nut 6 abuts against the second pressure plate 43, while the first pressure plate 42 abuts against the swing frame beam 1.

[0043] Optionally, the first pressing plate 42 , the second pressing plate 43 and the cylinder 41 are detachably connected.

[0044] In this embodiment, the abutment member 4 adopts a split structure, and the first pressure plate 42, the second pressure plate 43 and the cylinder 41 are all detachably connected. Compared with the integrated structure, the wall thickness of the cylinder 41 of this embodiment can be made thinner, which is beneficial to reduce the weight of the structure, making the entire installation tool lighter and more portable, and the installation operation is also more convenient.

[0045] Optionally, a first boss 421 is provided on a side of the first pressing plate 42 facing the cylinder 41 , and an outer diameter of the first boss 421 is adapted to an inner diameter of the cylinder 41 .

[0046] like Figure 3 As shown, in order to further improve the connection reliability between the first pressure plate 42 and the cylinder 41, a first boss 421 is processed on the side of the first pressure plate 42 facing the cylinder 41, and the outer diameter of the first boss 421 is adapted to the inner diameter of the cylinder 41, so that when the first pressure plate 42 is connected to the cylinder 41, the first boss 421 can be just embedded in the cylinder 41, realizing the snap-fit ​​between the first pressure plate 42 and the cylinder 41, ensuring that the first pressure plate 42 can be pressed tightly against the cylinder 41 during use to prevent relative sliding between the first pressure plate 42 and the cylinder 41, thereby affecting the normal use of the tool.

[0047] Optionally, a slot is provided on the side of the swing frame beam 1 facing the first pressure plate 42, and a second boss 422 adapted to the slot is provided on the side of the first pressure plate 42 facing the swing frame beam 1, and the second boss 422 is engaged with the slot.

[0048] Furthermore, in order to ensure that the first pressure plate 42 and the swing frame beam 1 can be pressed tightly during use, a card slot is opened on the side of the swing frame beam 1 facing the first pressure plate 42, and the diameter of the card slot is larger than the diameter of the pin shaft mounting hole. A second boss 422 is set on the side of the first pressure plate 42 facing the swing frame beam 1, and the outer diameter of the second boss 422 is adapted to the diameter of the card slot. Therefore, when the first pressure plate 42 and the swing frame beam 1 are pressed tightly, the second boss 422 is just embedded in the card slot, realizing the card connection between the first pressure plate 42 and the swing frame beam 1, thereby preventing relative sliding between the first pressure plate 42 and the swing frame beam 1, and ensuring stability and reliability during use.

[0049] Optionally, a third boss 431 is provided on a side of the second pressure plate 43 facing the cylinder 41 , and an outer diameter of the third boss 431 is adapted to an inner diameter of the cylinder 41 .

[0050] like Figure 4 As shown, in order to further improve the connection reliability between the second pressure plate 43 and the cylinder 41, a third boss 431 is processed on the side of the second pressure plate 43 facing the cylinder 41, and the outer diameter of the third boss 431 is adapted to the inner diameter of the cylinder 41, so that when the second pressure plate 43 is connected to the cylinder 41, the third boss 431 can be just embedded in the cylinder 41, realizing the snap-fit ​​between the second pressure plate 43 and the cylinder 41, ensuring that the second pressure plate 43 can be pressed tightly against the cylinder 41 during use to prevent relative sliding between the second pressure plate 43 and the cylinder 41, thereby affecting the normal use of the tool.

[0051] Furthermore, the mounting shaft 3 and the pin shaft 2 are connected via a connecting member 5 .

[0052] Furthermore, in order to facilitate the connection between the installation shaft 3 and the pin shaft 2, a connecting member 5 is provided in this embodiment, and the connecting member 5 can be connected to the installation shaft 3 and the pin shaft 2 at the same time.

[0053] Optionally, the connecting member 5 includes a connecting sleeve, the interior of which is provided with an internal thread, one end of the connecting sleeve is threadedly engaged with the pin shaft 2, and the other end of the connecting sleeve is threadedly engaged with the mounting shaft 3.

[0054] Specifically, in this embodiment, the connecting member 5 adopts a connecting sleeve, and the internal thread of the entire shaft section is processed inside the connecting sleeve, which can cooperate with the external thread on the installation shaft 3 and the external thread at the tail end of the pin shaft 2. In this way, the installation shaft 3 and the pin shaft 2 can be connected to the connecting member 5 at the same time.

[0055] The outer diameter of the connecting sleeve needs to be smaller than the diameter of the pin shaft mounting hole to ensure that the connecting sleeve can be inserted into the pin shaft mounting hole to connect with the pin shaft 2; the diameter of the through hole opened in the center of the first pressure plate 42 needs to be larger than the outer diameter of the connecting sleeve to ensure that when the pin shaft 2 is pulled to move axially, the connecting sleeve can smoothly enter the cylinder 41 through the through hole on the first pressure plate 42.

[0056] In other embodiments, a connecting portion may be directly formed on the end of the mounting shaft 3 close to the pin 2 , and an internal threaded hole may be correspondingly provided in the connecting portion to cooperate with the external thread at the rear end of the pin 2 .

[0057] Furthermore, an observation hole 411 is provided on the side wall of the cylinder 41 .

[0058] See also Figure 2 In this embodiment, a circular observation hole 411 is provided on the side wall of the cylinder 41. This observation hole 411 is located near the end of the swing frame beam 1. Through this observation hole 411, the interior of the cylinder 41 can be observed. Once the pin 2 is installed, the tail end of the pin 2 will pass through the pin installation hole and extend beyond the swing frame beam 1. The position of the observation hole 411 corresponds exactly to the position of the tail end of the pin 2 after installation. Therefore, through this observation hole 411, it can be determined whether the tail end of the pin 2 has reached the target position, thereby determining whether the pin 2 is properly installed. If the tail end of the pin 2 can be observed through the observation hole 411, the pin 2 is considered to be properly installed. If not, the operator must continue to rotate the nut 6 until the pin 2 is properly installed.

[0059] The process of installing the pin 2 on the swing frame beam 1 using the vibrator swing frame pin installation tool provided in the embodiment of the present application is as follows:

[0060] First, use the connecting sleeve to connect the installation shaft 3. Pass the end of the installation shaft 3 connected with the connecting sleeve through the pin installation hole from one side of the swing frame beam 1. Then connect the connecting sleeve to the tail end of the pin 2.

[0061] Install the first pressing plate 42, cylinder 41, second pressing plate 43 and nut 6 onto the mounting shaft 3 in sequence. Apply pre-tightening force to the swing frame beam 1 by tightening the nut 6, so that the second pressing plate 43, cylinder 41 and first pressing plate 42 press the swing frame beam 1 tightly.

[0062] Connect a crowbar to the installation shaft 3. The operator holds the crowbar with one hand to prevent the installation shaft 3 from rotating. With the other hand, the operator continues to tighten the nut 6 with a wrench or other tool to increase the pre-tightening force, so that the installation shaft 3 pulls the pin 2 to move into the pin installation hole. Observe through the observation hole 411 on the cylinder 41. When the tail end of the pin 2 can be seen through the observation hole 411, it indicates that the pin 2 has been installed in place.

[0063] Remove the crowbar, nut 6, second pressure plate 43, cylinder 41, and first pressure plate 42 from the mounting shaft 3 in sequence, remove the mounting shaft 3 and the connecting sleeve, screw the matching pin nut on the tail end of the pin 2 and lock it, and the installation of the pin 2 is completed.

[0064] The controllable seismic source swing frame pin shaft installation tool provided in the embodiment of the present application, through the cooperation of the nut 6, the abutment 4, the installation shaft 3 and the limit member 7, when installing the pin shaft 2, can drive the installation shaft 3 to move axially by rotating the driving nut 6, thereby cleverly pulling the pin shaft 2 axially into the pin shaft installation hole, thereby realizing the quick installation of the pin shaft 2 on the swing frame beam 1, easy operation, and no need to use a crane for lifting operations, which greatly improves the efficiency of maintenance.
