Description

Technical Field

[0001] This utility model relates to a quenching waiting rack for oil drilling gears. Background Technology

[0002] In the oil drilling and production field, gears are key components, and their performance directly affects the operating efficiency and lifespan of equipment. Quenching is an important process for improving gear performance. After quenching, gears need to be cooled in a cooling tank before being transferred to the next process.

[0003] After traditional gear quenching, they are mostly placed directly in a cooling tank for cooling. With the gear at the bottom of the cooling tank, the contact area between the cooling medium and the gear is small, causing the temperature of the cooling medium in some areas to rise continuously. This results in low cooling efficiency of the gear and affects production efficiency.

[0004] Meanwhile, after cooling is complete, each item needs to be manually removed one by one. The lack of a convenient removal mechanism makes manual operation cumbersome and laborious.

[0005] Therefore, a quenching waiting rack for oil drilling gears is proposed. Utility Model Content

[0006] The purpose of this invention is to provide a quenching waiting rack for oil drilling gears, in order to solve the problem of low cooling efficiency in traditional gear quenching mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a quenching waiting frame for oil drilling and production gears, comprising two sets of guide rails disposed on the inner wall of the cooling tank of oil drilling and production gears, a bearing roller disposed between the two sets of guide rails, and a mounting frame for placing oil drilling and production gears disposed on both sides of the bearing roller.

[0008] The mounting frame is connected to the bearing roller via an elastic rotary assembly, so that the mounting frame can be rotated and reset on the bearing roller side via the elastic rotary assembly.

[0009] Preferably, the elastic rotary assembly includes elastic rotary grooves formed on both sides of the bearing roller. The interior of the elastic rotary groove is connected to the rotary sleeve via a torsion spring shaft. The outer periphery of the rotary sleeve is connected to the mounting frame via a limiting seat, so that the mounting frame can elastically rotate within the elastic rotary groove via the rotary sleeve.

[0010] Preferably, the bearing roller has a slot on one side of the elastic rotary groove, and the opening angle of the slot is 60°. The opening directions of the two slots are opposite. This allows the connected mounting frame to deflect according to a set angle and direction, limiting the deflection angle of the mounting frame and preventing the gears from slipping off the mounting frame during placement or cooling due to excessive deflection. Simultaneously, the opposite deflection directions of the two sets of mounting frames help to distribute the weight evenly between them, avoiding excessive gear stacking on one side and ensuring balance.

[0011] Preferably, the opening directions of the grooves on both sides of the bearing roller are opposite, so that the deflection directions of the two sets of mounting frames are opposite.

[0012] Preferably, the middle of the bearing roller is connected to a grip tube via a connecting rod, so that the operator can use the grip tube to move the bearing roller out from between the two sets of guide rails.

[0013] Preferably, the outer periphery of the mounting frame is provided with a limiting protrusion, and the limiting protrusion cooperates with the shaft hole of the oil drilling gear so that the oil drilling gear can move linearly on the outer periphery of the mounting frame through the shaft hole.

[0014] Preferably, sliders are provided on both sides of the bearing roller, and the sliders cooperate with the guide rail.

[0015] Preferably, the two sets of guide rails have guide grooves inside that cooperate with the slider, and the two sets of guide rails are open at the top of the guide grooves. The guide rails are fixedly installed on the inner wall of the oil drilling gear cooling tank, providing a stable installation and sliding track for the bearing roller, ensuring that the bearing roller can move or be positioned smoothly in the cooling tank. At the same time, the opening allows the slider to be moved out from inside the guide rail.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention, through the structural design of the supporting roller and the mounting frame, allows the oil drilling gear to be placed in the cooling tank in a suspended or overhead manner. Compared with the traditional method of placing it directly at the bottom of the cooling pool, this increases the contact area between the gear and the cooling medium, promotes rapid heat transfer, and improves the cooling speed.

[0018] The gears are placed on the overhead frame, which reduces obstruction to the flow of the cooling medium, allowing the cooling medium to circulate more smoothly in the cooling tank, avoiding excessively high local temperatures, further improving cooling efficiency, shortening the production cycle, and increasing production efficiency.

[0019] The flexible rotating component allows the mounting bracket to adaptively adjust its position and rotate back to its original position. At the same time, the limiting protrusion cooperates with the gear shaft hole to prevent the gear from deflecting and falling off the mounting bracket, ensuring that the gear remains stable during the cooling process, reducing the risk of displacement caused by external forces or gravity, and reducing collision damage.

[0020] The bearing roller is connected to the grip tube via a connecting rod. Workers can easily move the bearing roller and gears out of the guide rails with the help of the grip tube, without having to move the gears one by one. This saves time and effort, reduces the intensity of manual operation and the risk of error, and improves work efficiency. Attached Figure Description

[0028] To address the problem of low cooling efficiency in traditional gear quenching, this utility model provides a quenching waiting rack for oil drilling gears. The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] Please see Figure 1-6This utility model provides a quenching waiting rack for oil drilling gears, including two sets of guide rails 1 disposed on the inner wall of the oil drilling gear cooling tank. A bearing roller 2 is disposed between the two sets of guide rails 1. The bearing roller 2 has a slot 23 on one side of the elastic rotary groove 41, and the opening angle of the slot 23 is 60°. The opening directions of the slots 23 on both sides of the bearing roller 2 are opposite, so that the deflection directions of the two sets of mounting frames 3 are opposite. A gripping tube 22 is connected to the middle of the bearing roller 2 through a connecting rod 21, so that the operator can move the bearing roller 2 out from between the two sets of guide rails 1 through the gripping tube 22.

[0030] The bearing roller 2 is provided with mounting frames 3 on both sides for mounting oil drilling gears; the mounting frames 3 are connected to the bearing roller 2 through the elastic rotation component 4 so that the mounting frames 3 can be rotated and reset on the side of the bearing roller 2 through the elastic rotation component 4.

[0031] The elastic rotary assembly 4 includes elastic rotary grooves 41 formed on both sides of the bearing roller 2. The interior of the elastic rotary grooves 41 is connected to the rotary sleeve 43 via a torsion spring shaft 42. The outer periphery of the rotary sleeve 43 is connected to the mounting frame 3 via a limiting seat 44, so that the mounting frame 3 can rotate elastically inside the elastic rotary grooves 41 via the rotary sleeve 43.

[0032] The outer periphery of the mounting frame 3 is provided with a limiting protrusion 31, and the limiting protrusion 31 cooperates with the shaft hole of the oil drilling gear so that the oil drilling gear can move linearly on the outer periphery of the mounting frame 3 through the shaft hole.

[0033] The bearing roller 2 is provided with sliders 5 on both sides, and the sliders 5 cooperate with the guide rail 1.

[0034] The two sets of guide rails 1 have guide grooves 11 inside that cooperate with the slider 5, and the top of the two sets of guide rails 1 are open.

[0035] The working principle of the oil drilling gear quenching waiting rack provided by this utility model is as follows: two sets of guide rails 1 are fixedly installed on the inner wall of the oil drilling gear cooling tank. The guide rails 1 are provided with guide grooves 11 inside, and the top of the guide grooves 11 is open to facilitate the installation and movement of the bearing rollers 2 and related components.

[0036] The quenched oil drilling gears are fitted one by one onto the mounting frame 3. Due to the force on the mounting frame 3, the connecting rotary sleeve 43 deflects at the elastic rotary groove 41. At the same time, the rotary sleeve 43 is connected to the limiting seat 44, which deflects at the groove opening 23 through the torsion spring shaft 42. The torsion spring shaft 42 is subjected to force and generates elastic torsion, thereby offsetting part of the gravity of the gears and reducing the pressure on the mounting frame 3.

[0037] The opening angle of the slot 23 is 60°, and the opening directions of the slots 23 on both sides of the bearing roller 2 are opposite. This design can effectively limit the deflection angle of the mounting frame 3 and prevent the gear from slipping out of the mounting frame 3 due to excessive deflection during the placement process, thus ensuring the stability and safety of the placement process.

[0038] During the cooling process, the bearing roller 2, the mounting frame 3 on it, and the oil drilling gear are located in the cooling tank. The cooling medium circulates in the cooling tank. Through the structural design of the bearing roller 2 and the mounting frame 3, the gears are in full contact with the cooling medium, thereby improving the cooling efficiency.

[0039] After cooling, the workers hold the connecting rod 21 in the middle of the bearing roller 2 through the grip tube 22 and apply appropriate tension or thrust.

[0040] With the help of the sliders 5 on both sides of the bearing roller 2 and the guide grooves 11 on the guide rail 1, the bearing roller 2, together with the mounting frame 3 and the cooled gear, is smoothly moved out from between the two sets of guide rails 1. The operation is simple and convenient, which greatly reduces the workload and risk of manually removing the gears one by one and improves work efficiency.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
