A new type of derrick bearing pin lubricating mechanism

Abstract

This utility model relates to the field of derrick technology, specifically a novel derrick bearing pin lubrication mechanism, including a fixed adjustment mechanism. The fixed adjustment mechanism includes a fixed base, a first connecting shaft, a long rod, a hydraulic cylinder, a second connecting shaft, and a first adjusting arm. In use, the fixed base is first fixed to one side of the derrick using fixing bolts through the first fixing screw hole of the supporting fixed plate and the second fixing screw hole of the fixing buckle, respectively, to ensure overall stability. When lubrication is required, the hydraulic cylinder at the top of the long rod is activated, pushing the second connecting shaft at the top upward, causing the first adjusting arm to rotate, which in turn causes the adjusting rod and the first and second pin modules connected to the connecting adjusting rod through the third connecting shaft and the second adjusting arm to move, pulling the bearing pin body out of the derrick. Then, it is lubricated with No. 3 lithium-based grease. After completion, the bearing pin body can be reset through the various adjustment structures.

Description

Technical Field

[0001] This utility model relates to the field of derrick technology, specifically a novel derrick bearing pin lubrication mechanism. Background Technology

[0002] The load-bearing mechanism is the connecting component between the upper and lower parts of the derrick. It transfers all the loads borne by the upper part of the derrick to the lower part of the derrick. Structurally, it must ensure the verticality and stability of the derrick and ensure the safe, smooth, and proper extension of the upper part of the derrick. It is one of the main components of the derrick. Utility Model Content

[0003] The purpose of this utility model is to provide a novel lubrication mechanism for derrick bearing pins to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A novel derrick bearing pin lubrication mechanism includes a fixed adjustment mechanism. The fixed adjustment mechanism includes a fixed base, a first connecting shaft, a long rod, a hydraulic cylinder, a second connecting shaft, and a first adjusting arm. The first connecting shaft is rotatably mounted on the top of the fixed base. The long rod is movably mounted on the top of the first connecting shaft. The hydraulic cylinder is fixedly mounted on the top of the long rod. The second connecting shaft is rotatably mounted on the top of the hydraulic cylinder. The first adjusting arm is movably mounted on one side of the second connecting shaft.

[0006] A lubrication adjustment mechanism is fixedly provided on one side of the first adjusting arm. The lubrication adjustment mechanism includes a connecting adjusting rod, a fixing buckle, a first pin module and a second pin module. Fixing buckles are fixedly provided on both sides of the connecting adjusting rod. A first pin module is movably provided on one side of the connecting adjusting rod. A second pin module is movably provided on the side of the connecting adjusting rod away from the first pin module.

[0007] Preferably, the connecting adjustment rod includes a fixed sleeve, and an adjustment insert is rotatably arranged inside the fixed sleeve. The adjustment insert is connected to the first adjustment arm. The advantage is that during use, the second connecting shaft at the top of the long rod is pushed upward by the hydraulic cylinder at the top of the long rod, which drives the first adjustment arm to rotate. This, in turn, drives the adjustment insert, the first pin module, and the second pin module to pull the pin body out of the derrick, and then lubricates it by using No. 3 lithium-based grease.

[0008] Preferably, the first pin module and the second pin module each include a third connecting shaft. A second adjusting arm is movably disposed at the top of the third connecting shaft, and a load-bearing pin body is movably disposed on one side of the top of the second adjusting arm. The advantage is that the load-bearing pin body is movably disposed on one side of the top of the second adjusting arm, which can improve the overall assembly adaptability and usage stability of the pin through the independent configuration and linkage of the two pin modules. The load-bearing pin body can be pulled out for lubrication when lubrication is required.

[0009] Preferably, a support plate is fixedly installed at the bottom of the fixed base, which has the advantage of improving the stability of the overall structure of the device.

[0010] Preferably, the support fixing plate is provided with first fixing screw holes on both sides. The advantage is that the fixing bolts fix the fixing base to one side of the derrick, which effectively ensures stability.

[0011] Preferably, the fixing buckle has second fixing screw holes on both sides. The advantage is that the fixing bolts fix the connecting adjustment rod to one side of the fixing adjustment mechanism, which provides an efficient adjustment method while ensuring stability and effectively improving practicality.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This novel derrick support pin lubrication mechanism, in use, firstly uses fixing bolts to fix the base to one side of the derrick and the connecting adjusting rod to one side of the fixing adjusting mechanism via the first fixing screw hole of the support fixing plate and the second fixing screw hole of the fixing buckle, respectively, to ensure overall stability. When lubrication is required, the hydraulic cylinder at the top of the long rod is activated, pushing the second connecting shaft at the top upward, driving the first adjusting arm to rotate, which in turn drives the adjusting rod and the first and second pin modules connected to the connecting adjusting rod via the third connecting shaft, the second adjusting arm and the connecting adjusting rod to move, pulling the support pin body out of the derrick. Then, it is lubricated with No. 3 lithium-based grease. After completion, the support pin body can be reset through the various adjusting structures.

[0014] This novel derrick support pin lubrication mechanism ensures the stability of the overall structure during operation through a stable connection between the fixed base and the supporting plate, and a reliable fixation between the connecting adjustment rod and the fixed adjustment mechanism. Utilizing a hydraulic cylinder to drive the first adjusting arm and related components in linkage, it enables convenient extraction and resetting of the support pin body. Combined with the independent configuration and linkage design of the dual pin modules, it improves the assembly adaptability and operational stability of the pins. This not only makes lubrication operations more convenient and efficient but also enhances the adjustment accuracy and load-bearing reliability of the pin structure. Furthermore, the design of the fixing buckle provides an efficient adjustment method while ensuring stability, significantly improving the practicality and applicability of the mechanism.
