Description

Technical Field

[0001] This utility model relates to a semi-open tensioning machine base for a pure electric rotary drilling motor, belonging to the field of motor technology. Background Technology

[0002] The motors used in pure electric rotary drilling equipment are generally vertically assembled. The motor assembly interface is usually assembled and constrained at the front flange. Since the rotary drilling equipment experiences significant vibration and impact during operation, the motor as a whole needs to withstand greater impact than in common operating conditions. To simplify the process, the motor base is made of extruded aluminum profile and features an open water channel for heat dissipation.

[0003] Referring to the utility model patent application filed by the applicant recently, with publication number CN221202280U, entitled "A Housing Structure for a Water-Cooled Motor", this patent achieves sealing by embedding stainless steel brackets with sealing gaskets at both ends of the base and pressing them together with the end caps. However, due to the strong vibration and impact of rotary drilling equipment, the structure of relying solely on sealing gaskets between the front face of the base and the front cover is prone to gaps, posing a risk of water leakage, which may affect heat dissipation or even damage the motor. Therefore, a new solution is needed to address this problem. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a semi-open tensioning machine base for a pure electric rotary drilling motor.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a semi-open tension base for a pure electric rotary drilling motor, comprising a base body, the base body being annular, and having multiple water-cooling channels extending through its length along the circumferential direction on the base body, the water-cooling channels being used to store cooling water;

[0006] One end of the base body is a sealed end, and the other end is an open end; the sealed end of the base body is provided with a plurality of sealing welding blocks, the cross-sectional shape of the sealing welding blocks is consistent with the cross-sectional shape of the water cooling channel, the sealing welding blocks are embedded in the end of the water cooling channel, and are fused to the base body by welding to seal the water cooling channel.

[0007] Both the sealed end and the open end of the base body are used to fit the end cover of the motor.

[0008] Preferably, the plurality of water-cooling channels are evenly distributed along the circumference of the base body, and water channel ribs are formed between adjacent water-cooling channels.

[0009] Preferably, the outer end face of the sealing weld block is flush with the outer end face of the base body.

[0010] Preferably, each of the water-cooling channels has multiple continuous grooves on its outer wall.

[0011] Preferably, both ends of the base body are integrally machined with connecting rings, and the base body uses the connecting rings at both ends to position the end cover of the motor.

[0012] Preferably, the base body is formed by extrusion of aluminum profile.

[0013] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0014] This utility model discloses a semi-open tension base for a pure electric rotary drilling motor. By welding a sealing block to one end of the base body, the sealing block and the base form an integrated sealing structure for the cooling water channel, which can adapt to working conditions with large vibration and impact and avoid heat dissipation failure caused by water leakage. The other end of the base body is an open structure with a large opening, which makes it easy to clean the processing debris and does not require complicated protection to ensure that the water channel is clean and free of foreign objects.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0021] As attached Figure 1-4 As shown, the present invention discloses a semi-open tension base for a pure electric rotary drilling motor, which is applicable to the vertical assembly motor of a pure electric rotary drilling equipment. It aims to solve the problems of water leakage and unstable heat dissipation of the motor base caused by strong vibration and impact of the rotary drilling equipment. It includes a base body 1, which is circular.

[0022] The base body 1 is formed by extruding aluminum profiles to ensure the consistency and integrity of the overall structure of the base body 1, avoid structural weaknesses caused by segmented processing, improve the base's resistance to vibration and impact, and adapt to the harsh working conditions of rotary drilling equipment.

[0023] The base body 1 has multiple water-cooling channels 2 extending through its length along the circumference. The water-cooling channels 2 are used to store cooling water. In this embodiment, the number of water-cooling channels 2 is set to 10. In actual processing and use, the number of water-cooling channels 2 can be increased or decreased according to the actual situation to meet the actual heat dissipation requirements. No limitation is made here.

[0024] Furthermore, multiple water-cooling channels 2 are evenly distributed along the circumference of the base body 1 to ensure that the heat can be evenly removed when the motor is working, avoiding local overheating; water channel ribs 4 are formed between adjacent water-cooling channels 2. The water channel ribs 4 can not only separate each water-cooling channel 2 to prevent the cooling water from mixing in the channel and affecting the heat dissipation efficiency, but also serve as reinforcing ribs of the base body 1 to improve the radial stiffness of the ring structure and further enhance the vibration and shock resistance of the base.

[0025] Furthermore, each of the water-cooling channels 2 has multiple continuous grooves 8 on its outer wall to increase the contact area between the base body 1 and the cooling water, thereby improving heat dissipation efficiency.

[0026] One end of the base body 1 is a sealed end, and the other end is an open end, forming a semi-open base structure with one end sealed and the other end open. Specifically, the sealed end of the base body 1 is provided with multiple sealing welding blocks 3. The cross-sectional shape of the sealing welding blocks 3 is consistent with the cross-sectional shape of the water cooling channel 2. The sealing welding blocks 3 are embedded in the end of the water cooling channel 2 and are fused to the base body 1 by welding to seal the water cooling channel 2. This avoids the failure of the base cooling channel due to water leakage caused by the loosening of traditional bolts.

[0027] In this embodiment, the number of sealing welding blocks 3 corresponds to the number of water cooling channels 2, and both are 10. In actual use, the number of sealing welding blocks 3 is changed according to the number of water cooling channels 2.

[0028] Furthermore, the outer end face of the sealing weld block 3 is flush with the outer end face of the machine base body 1. This can avoid assembly interference caused by the protrusion of the sealing weld block 3, and ensure that there is no gap in the sealing surface.

[0029] In application, both the sealed end and the open end of the base body 1 are used to fit the end cover of the motor. Specifically, both ends of the base body 1 are integrally machined with connecting rings 5. The base body 1 uses the connecting rings 5 ​​at both ends to position the end cover of the motor. During assembly, the end cover of the motor can be quickly positioned through the connecting rings 5 ​​to improve the assembly speed.

[0030] The sealed end of the base body 1 is directly connected to the end cover of the motor through the connecting ring 5, while the open end of the base body 1 can be sealed by using a traditional sealing gasket in conjunction with the end cover for compression.

[0031] It should be noted that after the base body 1 is assembled with the motor, the motor needs to be connected to the rotary drilling equipment. The sealed end of the base body 1 is connected to the rotary drilling equipment. Because it is close to the vibration source, the integrated sealing structure will not crack, which can ensure that the cooling water does not leak, thereby ensuring the continuous cooling effect of the motor.

[0032] The above are merely specific application examples of this utility model and do not constitute any limitation on the scope of protection of this utility model; all technical solutions formed by equivalent transformation or equivalent substitution fall within the scope of protection of this utility model.
