Description

Technical Field

[0001] The utility model relates to the technical field of engineering machinery, in particular to a safe and reliable climbing rod lifting device for geological drilling. Background Art

[0002] At present, the lifter is an essential tool for lifting and lowering drill bits in the geological drilling industry. The advantage of the climbing pole lifter is that it does not require an operator on the drilling tower and there is no need for high-altitude operations, which not only reduces labor intensity but also avoids the safety hazards caused by high-altitude operations.

[0003] The authorization announcement number in the prior art is: CN214616410U, and the name is a lifter, which includes: a spindle, a hook, a connecting flange, an oil seal, an angular contact bearing, a thrust bearing, a locking nut, a gasket and a ball bearing. The gasket and the ball bearing are arranged behind the thrust bearing to eliminate the gap between the spindle and the hook and improve the force condition. The lifter is also provided with an oil filling port to facilitate oil filling inside, optimize the working condition, and reduce oil leakage;

[0004] However, the self-locking state of this patent is supported by springs. In the event of a drill stop or rapid lifting of the drill tool, there is a high probability that the self-locking state will fail, causing the lifter to fail and leading to a drilling safety accident. This patent is extremely inconvenient in the operation of stacking roots, and ground workers are often required to forcefully move the drill rod to give the lifter a bias so that the drill rod can pass through the front of the lifter, which increases the workers' physical strength and makes the equipment more inconvenient to use.

[0005] The authorization announcement number in the prior art is: CN203742482U, and the name is improved lifting, which includes: a lifting device body and a lifting ring, the lifting ring is installed on the top of the body, a thrust ball bearing is installed on the top, the hoop is slidable on the body, there are triangular positioning grooves on both sides, a card groove is provided at the bottom of the body, and an elastic positioning nail matching the triangular positioning groove is provided on the top of the inner wall. This structure makes the wire rope stable and not easy to deviate when lifting the active drill rod, avoiding the slip phenomenon;

[0006] However, the self-locking state of this patent is supported by springs. In the event of a drill stop or rapid lifting of the drill bit, there is a high probability that the self-locking state will fail, causing the lifter to fail and leading to a drilling safety accident.

DETAILED DESCRIPTION

[0038] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] Example 1

[0040] like Figure 1 - Fig.17 As shown, the present embodiment proposes a safe and reliable climbing rod lifter for geological drilling, including a device body 22, a shaft sleeve 2 is fixedly connected inside the device body 22, a bearing 3 is arranged inside the shaft sleeve 2, a locking pin 6 is installed inside the bearing 3, a lifting ring 1 is fixedly connected to the top of the locking pin 6, a large nut 5 is threadedly sleeved on the outer circumferential surface of the locking pin 6, a large gasket 4 is arranged inside the device body 22, a fixing pin 15 is installed inside the device body 22, a door 16 is arranged on the device body 22, a horseshoe 19 is installed inside the device body 22, and a closing pin 9 is arranged on the device body 22. Through the arrangement of structures such as the horseshoe 19 and the door 16, the winch goes down, and the lifter carries the drill rod into the borehole. In case of drill jam or drill stop, a closing pin 9 is added to the new lifter. Double insurance ensures the stability of the door 16, allowing the mushroom head to safely and quickly enter the horseshoe 19 limit position, avoid drilling, and ensure the safety of drilling tools.

[0041] like Figure 1 - Figure 7 As shown, a thread groove 1 is provided inside the large nut 5, and the lock nut pin 6 is threadedly connected inside the thread groove 1.

[0042] like Figure 1 - Fig.10 As shown, a hole groove is provided inside the device body 22, and the closing pin 9 is slidably connected inside the hole groove.

[0043] The specific implementation principle of this embodiment is as follows: the winch goes downward, and the lifter hangs the drill rod into the borehole. When the drill is stuck or stuck, the lifter is separated from the mushroom head. In special cases, the drill tool will suddenly fall quickly. At this time, the weight of the drill tool will impact the lifter. When the mushroom head stably enters the horseshoe-shaped 19 limited position, it will generate a certain lateral force on the door 16, because the deformation forces the locking state of the positioning elastic pin 11 to fail (the main reason for the unsafe climbing rod lifter in the past). However, the device body 22 has an additional closing pin 9, which ensures that the door 16 is firmly closed under the dual action, ensuring that the mushroom head safely enters the horseshoe-shaped 19 limiting groove under rapid impact, avoiding drill runaway accidents and ensuring the safety of the drill tool.

[0044] Example 2

[0045] like Figure 1 - Fig.17 As shown, this embodiment also introduces a safe and reliable climbing rod lifter for geological drilling, which adds the following structure on the basis of the first embodiment: a guide plate 8 is installed on the device body 22, a small gasket 14 is arranged inside the device body 22, a cantilever assembly 21 is arranged on the device body 22, a suspension arm 7 is arranged on the cantilever assembly 21, a rotating sleeve 10 is arranged on the device body 22, a positioning elastic pin 11 is arranged inside the rotating sleeve 10, a small nut 13 is arranged on the rotating sleeve 10, a middle nut 18 is arranged on the device body 22, a rotating shaft 20 is installed inside the device body 22, and a pulley 17 is arranged on the rotating shaft 20. Through the arrangement of the positioning elastic pin 11, the closing pin 9 and other structures, when using the climbing rod lifter, first remove the closing pin 9, pull the positioning elastic pin 11 with the right hand to open the door 16 with the pulley 17, hang the drill rod, and then close the door 16 counterclockwise, fix it with the positioning elastic pin 11, and finally insert the closing pin 9, so that the equipment is more convenient to use.

[0046] like Figure 1 - Fig.12 As shown, a hole groove is arranged inside the device body 22, and a positioning elastic pin 11 is slidably connected inside the hole groove. A spring 12 is commonly connected between the positioning elastic pin 11 and the inner wall of the hole groove.

[0047] like Figure 1 - Fig.14As shown, a circular groove is provided inside the device body 22, and the pulley 17 is rotatably installed inside the circular groove.

[0048] like Figure 1 - Fig.12 As shown, a thread groove three is provided inside the small nut 13, and the positioning elastic pin 11 is threadedly connected inside the thread groove three.

[0049] like Figure 1 - Fig.13 As shown, a second thread groove is provided inside the middle nut 18, and the fixing pin 15 is threadedly connected inside the second thread groove.

[0050] The specific implementation principle of this embodiment is as follows: when using the pole climbing lifter, first remove the closing pin 9, then pull the positioning elastic pin 11 with the right hand, and open the door 16 with the pulley 17 clockwise. Then hang the mushroom head (drill rod) on the horseshoe 19, then close the door 16 counterclockwise, limit the position with the positioning elastic pin 11, and finally insert the closing pin 9, the winch pulls the wire rope, the pole climbing lifter goes up along the drill rod, and after reaching the mushroom head, the mushroom head follows the horseshoe 19 limiting groove to a fixed position, the pole climbing lifter lifts the drill rod, and the worker connects the drill rod in the hole, making the equipment more convenient to use.

[0051] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
