Description

Technical Field

[0001] This utility model belongs to the field of downhole equipment technology, and specifically relates to a quick installation device for a direct drive system of a downhole conveyor belt. Background Technology

[0002] In downhole conveyor direct drive systems, the efficiency of replacing electric drums directly determines the downtime for downhole production. Traditional electric drum installation relies on multiple sets of bolts for fastening or welding. In the confined space and dim, dusty environment of downhole operations, bolts are prone to rust and jamming. It takes 2-3 operators working together for several hours to complete the replacement, far exceeding the downtime window that production can tolerate. Existing technologies lack targeted rapid disassembly and assembly structures. Bolt tightening is cumbersome and labor-intensive, while welding fixation has problems such as high cutting risks during disassembly and easy damage to the mounting frame. None of these can meet the needs of efficient operation and maintenance. Downhole vibration can easily cause traditional fixing structures to loosen, requiring additional maintenance costs. Utility Model Content

[0003] The purpose of this utility model is to provide a quick installation device for a direct drive system of downhole conveyor belts, which has the advantage of enabling quick replacement of the electric drum.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a quick installation device for a direct drive system of a downhole conveyor belt, including a mounting frame, a mounting base fixedly connected to the front and rear sides of the top of the mounting frame, an electric roller provided on the top of the mounting base, a fixing block provided on the top of the mounting base, the electric roller being movably connected to the inner side of the mounting base and the fixing block, and a fixing mechanism being provided inside the fixing block. The fixing mechanism includes slots, which are formed on both sides of the top of the mounting base, and the interior of the slots communicates with the interior of the fixing block.

[0005] The above technical solution utilizes a mounting base and a fixing block to confine the electric drum within both, followed by rapid fixing via a securing mechanism, replacing traditional complex installation methods such as bolt tightening and welding. This eliminates the need for heavy-duty fastening tools or on-site welding, significantly reducing the installation time of the electric drum. It is particularly suitable for scenarios with confined underground spaces and limited working conditions, effectively reducing the labor intensity and working hours of underground workers, improving the installation or replacement efficiency of belt conveyor direct drive systems, and ensuring the continuity of underground production.

[0006] The present invention is further configured such that the fixing mechanism includes a locking block, the locking block is engaged inside the locking slot, the top of the locking block extends into the interior of the fixing block, a transmission plate is movably connected to the inner side of the locking block, and a lifting block is movably connected to the inner side of the transmission plate.

[0007] The above technical solution employs the following: By setting the locking blocks, after the blocks are precisely engaged in the slots, a firm axial limit is formed, preventing the fixed blocks from separating from the mounting base, thereby ensuring the installation stability of the electric drum; at the same time, the movable connection design between the transmission plate and the lifting block allows the extension and retraction of the locking blocks to be controlled by a single drive source, eliminating the need to operate the locking blocks on both sides separately, simplifying the locking operation steps, and the locking force of the locking structure is evenly distributed on both sides of the mounting base, avoiding structural damage caused by excessive local stress, and adapting to the usage requirements of frequent installation, disassembly and maintenance in downhole environments.

[0008] The present invention is further configured such that a pull rod is fixedly connected to the top of the lifting block, the top of the pull rod extends through to the top of the fixed block, and a spring is fixedly connected to the top of the lifting block, the top of the spring being fixedly connected to the top of the inner wall of the fixed block.

[0009] The above technical solution achieves an elastic automatic locking function for the fixing mechanism through the pull rod: when the pull rod is released, the spring's restoring force pushes the lifting block downwards, driving the locking block to automatically engage in the slot via the transmission plate, eliminating the need for manual pressing of the locking block and simplifying the operation; pulling the pull rod moves the lifting block upwards, disengaging the locking block from the slot for quick unlocking. The entire locking and unlocking process can be completed simply by pulling the pull rod, making operation convenient and efficient, requiring no professional skills. Simultaneously, the spring's elasticity provides a continuous preload to the locking block, counteracting the impact of downhole vibrations on the locking structure, preventing the locking block from loosening, ensuring the locking reliability of the fixing mechanism, and the spring structure is wear-resistant, has low maintenance costs, and is suitable for harsh downhole working environments.

[0010] The present invention is further configured such that a pull ring is fixedly connected to the top of the pull rod, and the pull ring is located on the top of the fixing block.

[0011] The above technical solution utilizes a pull ring design. The ring's circular structure makes it easier for operators to grip, especially in low-light conditions downhole where workers are wearing gloves. This effectively prevents slippage and improves operational convenience and safety. Furthermore, the pull ring's prominent location at the top of the fixing block allows operators to quickly locate the operating position without repeatedly searching for the pull rod, further shortening installation and disassembly time and improving downhole efficiency. The pull ring's simple structure and high strength also make it resistant to damage from downhole collisions and friction, resulting in a long service life.

[0012] The present invention is further configured such that a crossbar is fixedly connected to the front and rear sides of the top of the inner part of the fixing block, and the locking block is slidably connected to the surface of the crossbar.

[0013] The above technical solution utilizes a crossbar to ensure smooth movement of the locking block along its surface during extension and retraction, preventing offset, jamming, or tilting. This ensures the block can accurately and smoothly engage and disengage from the slot, improving the smoothness of the fixing mechanism's operation. Simultaneously, the crossbar provides support and limits to the locking block, dispersing the radial force borne by the block in the locked state, preventing deformation or damage due to concentrated force, and extending the block's service life. Furthermore, the crossbar is fixed to the top of the fixing block's interior, resulting in a concealed and stable structure that does not compromise the overall compactness of the equipment, making it suitable for installation in confined underground spaces.

[0014] The present invention is further configured such that a stabilizing sleeve is fixedly connected to the surface of the card block, and the stabilizing sleeve is slidably connected to the surface of the crossbar.

[0015] The above technical solution reduces direct friction between the locking block and the crossbar by using a stabilizing sleeve, thus lowering component wear and preventing abnormal noises during block sliding, thereby improving equipment stability. The stabilizing sleeve provides more precise constraint on the sliding trajectory of the locking block, preventing it from shifting on the crossbar surface and ensuring it always moves in the preset direction, guaranteeing the locking accuracy of the locking structure. Furthermore, the stabilizing sleeve can be made of wear-resistant material, effectively resisting the erosion of the sliding structure by downhole dust and humid environments, extending the maintenance cycle of the fixing mechanism, and reducing the maintenance costs of downhole equipment.

[0016] The present invention is further configured such that reinforcing columns are fixedly connected to both sides of the top of the mounting base, and the top of the reinforcing columns extends to the top of the fixing block.

[0017] The above technical solution employs a double-support structure formed by reinforcing columns, further enhancing the connection strength between the mounting base and the fixing block. This prevents loosening or deformation at the connection point due to severe vibrations during the operation of the downhole conveyor belt, ensuring the overall stability of the electric drum installation. Simultaneously, the reinforcing columns, distributed on both sides of the top of the mounting base, provide auxiliary positioning for the fixing block, preventing displacement in the lateral or longitudinal directions. This ensures precise relative positioning between the fixing block and the mounting base, thereby guaranteeing the installation accuracy of the electric drum and preventing problems such as abnormal noise and accelerated wear caused by installation deviations.

[0018] The present invention is further configured such that the top of the reinforcing column is provided with an arc-shaped chamfer, and the arc-shaped chamfer is located on both sides of the top of the fixing block.

[0019] The above technical solution addresses several safety hazards associated with the reinforcement column. Firstly, the rounded chamfer avoids sharp edges on the top of the reinforcement column, preventing cuts and injuries to workers, especially in confined underground spaces with frequent worker movement, thus improving operational safety. Secondly, the rounded chamfer guides the installation and removal of the fixing block. When the fixing block is fitted into the reinforcement column, the rounded surface acts as a guide, preventing jamming due to installation deviations and ensuring smoother assembly, thus shortening installation time. Thirdly, the rounded chamfer reduces stress concentration at the top of the reinforcement column, preventing cracking and damage due to underground collisions, extending the column's service life, and ensuring the reliability of the structural support.

[0020] In summary, this utility model has the following beneficial effects: 1. This utility model, through the setting of a mounting base and a fixing block, confines the electric drum within the two, and then achieves rapid fixing with the aid of a fixing mechanism, replacing the complex installation methods such as traditional bolt tightening and welding. It eliminates the need to carry heavy-duty fastening tools or perform on-site welding operations, significantly shortening the installation time of the electric drum. It is particularly suitable for scenarios with confined underground spaces and limited working conditions, effectively reducing the labor intensity and working time of underground workers, improving the installation or replacement efficiency of belt conveyor direct drive systems, and ensuring the continuity of underground production. 2. This utility model, through the symmetrical arrangement of the front and rear sides of the top of the mounting base, can provide balanced support and limit for the electric drum, preventing lateral displacement or swaying after installation. At the same time, the cooperation between the fixing block and the mounting base forms a closed limiting space, constraining the electric drum in all directions within the installation area. Combined with the locking effect of the fixing mechanism, it ensures that the electric drum can maintain a stable installation state under complex underground working conditions (such as vibration of conveyor belt operation and roadway bumps), preventing equipment failure due to loosening and improving the reliability and safety of the direct drive system.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings. Example

[0024] refer to Figures 1-3 A quick installation device for a direct drive system of a downhole conveyor belt includes a mounting frame 1. Mounting seats 2 are fixedly connected to the front and rear sides of the top of the mounting frame 1. An electric roller 3 is provided on the top of the mounting seat 2. A fixing block 4 is provided on the top of the mounting seat 2. The electric roller 3 is movably connected to the inner side of the mounting seat 2 and the fixing block 4. A fixing mechanism 5 is provided inside the fixing block 4. The fixing mechanism 5 includes a slot 51, which is opened on both sides of the top of the mounting base 2, and the interior of the slot 51 is connected to the interior of the fixing block 4.

[0025] refer to Figure 4 The fixing mechanism 5 also includes a locking block 52, which is engaged inside the slot 51. The top of the locking block 52 extends into the interior of the fixing block 4. A transmission plate 53 is movably connected to the inner side of the locking block 52, and a lifting block 54 is movably connected to the inner side of the transmission plate 53. With the locking block 52 in place, after the locking block 52 is precisely engaged in the slot 51, it can form a firm axial limit, preventing the fixing block 4 from separating from the mounting base 2, thereby ensuring the installation stability of the electric drum 3. At the same time, the movable connection design between the transmission plate 53 and the lifting block 54 allows the extension and retraction of the locking block 52 to be controlled by a single drive source, eliminating the need to operate the locking blocks 52 on both sides separately, simplifying the locking operation steps. Moreover, the locking force of the locking structure is evenly distributed on both sides of the mounting base 2, avoiding structural damage caused by excessive local force, and adapting to the usage requirements of frequent installation, disassembly and maintenance in the well.

[0026] refer to Figure 3 A pull rod 55 is fixedly connected to the top of the lifting block 54, and the top of the pull rod 55 extends through to the top of the fixed block 4. A spring 56 is fixedly connected to the top of the lifting block 54, and the top of the spring 56 is fixedly connected to the top of the inner wall of the fixed block 4. The pull rod 55 enables the elastic automatic locking function of the fixing mechanism 5: when the pull rod 55 is released, the return force of the spring 56 pushes the lifting block 54 down, and drives the locking block 52 to automatically engage with the locking slot 51 through the transmission plate 53, eliminating the need to manually press the locking block 52 and simplifying the operation. The process involves pulling the lever 55 to move the lifting block 54 upward, causing the locking block 52 to disengage from the slot 51, thus achieving quick unlocking. The entire locking and unlocking process can be completed simply by pulling the lever 55, making it convenient and efficient to operate without requiring any professional skills. The elasticity of the spring 56 provides a continuous preload force to the locking block 52, offsetting the impact of downhole vibration on the locking structure, preventing the locking block 52 from loosening, and ensuring the locking reliability of the fixing mechanism 5. Furthermore, the spring 56 structure is wear-resistant, has low maintenance costs, and is suitable for harsh downhole working environments.

[0027] refer to Figure 3 A pull ring 6 is fixedly connected to the top of the pull rod 55. The pull ring 6 is located on top of the fixing block 4. The ring structure of the pull ring 6 makes it easier for operators to grip, especially in low-light conditions downhole where operators are wearing gloves. This effectively prevents slippage and improves the convenience and safety of operation. At the same time, the pull ring 6 is prominently located on top of the fixing block 4, allowing operators to quickly locate the operating part without repeatedly searching for the pull rod 55. This further shortens the operation time during installation or disassembly, improving the efficiency of downhole operations. Furthermore, the pull ring 6 has a simple structure, high strength, and is not easily damaged by collisions or friction downhole, resulting in a long service life.

[0028] refer to Figure 4 The crossbar 7 inside the fixing block 4 allows the locking block 52 to move smoothly along the surface of the crossbar 7 during extension and retraction, preventing the locking block 52 from shifting, jamming, or tilting. This ensures that the locking block 52 can accurately and smoothly engage or disengage from the slot 51, improving the smoothness of the operation of the fixing mechanism 5. At the same time, the crossbar 7 supports and limits the locking block 52, dispersing the radial force borne by the locking block 52 in the locked state, preventing deformation or damage caused by concentrated force, and extending the service life of the locking block 52. In addition, the crossbar 7 is fixed to the top inside the fixing block 4, making the structure concealed and stable, without affecting the overall compactness of the equipment, and adapting to the installation requirements of confined underground spaces. The front and rear sides of the part are fixedly connected to the crossbar 7, and the locking block 52 is slidably connected to the surface of the crossbar 7.

[0029] Brief description of usage: Figure 1 The mounting base 2 and the fixing block 4 are in the state where the electric roller 3 is fixed on the mounting frame 1. When the electric roller 3 needs to be removed, pull the pull ring 6 to move it upward. The pull ring 6 drives the pull rod 55 and the lifting block 54 to move upward. The lifting block 54 compresses the spring 56. The lifting block 54 drives the transmission plate 53 to rotate. The transmission plate 53 drives the two side locking blocks 52 to move inward. The locking blocks 52 and the locking grooves 51 separate, and the fixing block 4 loses its fixing effect. Move the fixing block 4 upward, and the fixing block 4 loses its fixing effect on the electric roller 3. The electric roller 3 can then be removed from the top of the mounting base 2. Example

[0030] refer to Figure 4A stabilizing sleeve 8 is fixedly connected to the surface of the locking block 52, and the stabilizing sleeve 8 is slidably connected to the surface of the crossbar 7. The stabilizing sleeve 8 reduces direct friction between the locking block 52 and the crossbar 7, lowers component wear, and prevents abnormal noises when the locking block 52 slides, thus improving the stability of equipment operation. The stabilizing sleeve 8 provides more precise constraint on the sliding trajectory of the locking block 52, preventing it from shifting on the surface of the crossbar 7 and ensuring that the locking block 52 always moves in the preset direction, guaranteeing the locking accuracy of the locking structure. Furthermore, the stabilizing sleeve 8 can be made of wear-resistant material, effectively resisting the erosion of the sliding structure by underground dust and humid environments, extending the maintenance cycle of the fixing mechanism 5, and reducing the maintenance cost of underground equipment.

[0031] refer to Figure 3 Reinforcing columns 9 are fixedly connected to both sides of the top of the mounting base 2. The top of the reinforcing columns 9 extends to the top of the fixing block 4. The setting of the reinforcing columns 9 forms a double support structure, which further enhances the connection strength between the mounting base 2 and the fixing block 4. This prevents the connection between the two from loosening or deforming due to the severe vibration of the downhole conveyor belt during operation, and ensures the overall stability of the electric drum 3 installation. At the same time, the reinforcing columns 9 are distributed on both sides of the top of the mounting base 2, which can play an auxiliary limiting role for the fixing block 4, preventing the fixing block 4 from shifting in the lateral or longitudinal direction. This ensures the accurate relative position of the fixing block 4 and the mounting base 2, thereby ensuring the installation accuracy of the electric drum 3 and avoiding problems such as abnormal noise and accelerated wear of the electric drum 3 caused by installation deviation.

[0032] refer to Figure 3 The top of the reinforcing column 9 is provided with an arc-shaped chamfer 10, which is located on both sides of the top of the fixing block 4. The arc-shaped chamfer 10 avoids the sharp edges of the top of the reinforcing column 9 from causing scratches, bumps, or other safety hazards to workers, especially in scenarios with confined underground spaces and frequent worker movement, thus improving the operational safety of the equipment. Secondly, the arc-shaped chamfer 10 guides the installation and removal direction of the fixing block 4. When the fixing block 4 is fitted into the reinforcing column 9, the arc-shaped surface acts as a guide, preventing the fixing block 4 from getting stuck with the reinforcing column 9 due to installation deviations, making the assembly of the fixing block 4 smoother and shortening the installation time. At the same time, the arc-shaped chamfer 10 reduces stress concentration at the top of the reinforcing column 9, preventing cracking and damage to the top of the reinforcing column 9 due to underground collisions, extending the service life of the reinforcing column 9, and ensuring the reliability of the structural support.

[0033] Brief description of the usage process: The crossbar 7 increases the stability of the lateral movement of the locking block 52 and increases the connection strength between the locking block 52 and the fixing block 4, preventing the fixing block 4 and the locking block 52 from being forcibly separated under force. The reinforcing column 9 positions the fixing block 4 to prevent the fixing block 4 from shaking on the top of the mounting base 2. The arc chamfer 10 reduces the area of ​​the top of the reinforcing column 9, making it easier for the reinforcing column 9 to be inserted into the interior of the fixing block 4.

[0034] It should be noted that parts have a lifespan and can be replaced during regular maintenance when they no longer meet performance requirements. Deterioration in performance due to prolonged use of parts is not a design defect of this application.
