Description

Technical Field

[0001] This application relates to the field of coal mine electromechanical systems, and more particularly to a lifting device for installing coal mine electromechanical systems. Background Technology

[0002] In the electromechanical installation work in coal mines, lifting devices for electromechanical installation bear the crucial responsibility of accurately transporting various installation components to designated locations. The working environment in coal mines is complex, with confined spaces and numerous uncertainties, which places stringent demands on electromechanical installation work.

[0003] Commonly used lifting devices for electromechanical installation in coal mines mainly include traditional winch-type hoists, hydraulic lifting platforms, and some customized rail transport equipment. These devices typically have basic lifting and transport functions, and can meet the needs of handling installation components under certain conditions.

[0004] However, existing hoisting devices for electromechanical installation in coal mines have significant defects, the most prominent of which is the inability to effectively stabilize the position of the installed components. When these components are transported on the hoisting device, due to the lack of a reliable position stabilization mechanism, they are highly susceptible to shaking caused by various factors during the hoisting process. This can lead to relative displacement of internal components, causing damage and affecting the normal operation of the equipment. In extreme cases, there is a risk that the components may fall off the hoisting device, not only damaging the components but also posing a direct threat to the lives of underground workers.

Detailed Implementation

[0044] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of this application.

[0045] Existing hoisting devices for electromechanical installation in coal mines have significant defects, the most prominent of which is the inability to effectively stabilize the position of the installed components. When these components are transported on the hoisting device, due to the lack of a reliable position stabilization mechanism, they are easily affected by various factors during the hoisting process, which may cause relative displacement of internal components, resulting in component damage and affecting the normal operation of the equipment. In extreme cases, there is a risk that the installed components may fall off the hoisting device, which may not only damage the components but also pose a direct threat to the life safety of underground workers.

[0046] The following detailed description, in conjunction with the accompanying drawings, illustrates the specific structure of the lifting device for electromechanical installation in coal mines provided in this application.

[0047] Reference Figure 1-6As shown in the embodiment of this application, a lifting device used in the installation of electromechanical equipment in underground coal mines is proposed, including: a lifting mechanism 1, which uses a hydraulic cylinder or scissor lift platform to achieve vertical movement and provide a stable and reliable lifting function; a clamping and stabilizing mechanism 2, which is fixedly installed on the top working surface of the lifting mechanism 1 and connected by high-strength bolts to ensure structural rigidity, so that the clamping and stabilizing mechanism 2 and the lifting mechanism 1 form an integral whole, avoiding relative displacement and improving overall stability; a sliding protection mechanism 3, which is slidably connected to the top opening of the clamping and stabilizing mechanism 2, and uses a sliding rail connection to achieve quick opening and closing, while providing top protection to prevent damage to the installation parts from falling objects underground; the clamping and stabilizing mechanism 2 includes: a placement box 21, the bottom of which is fixedly connected to the lifting mechanism 1, which can adapt to the clamping requirements of installation parts of different sizes; and a prevention plate 2. 2. The anti-blocking plate 22 is symmetrically arranged on both sides of the inner cavity of the placement box 21; the placement plate 24 is arranged at the bottom of the inner cavity of the placement box 21 and is used to support the installation parts; the positioning rod 25 passes through the placement plate 24 and the two ends of the positioning rod 25 are fixed in the guide groove of the placement box 21; the horizontally arranged connecting rod 26 is rigidly connected to the anti-blocking plate 22 by threaded fasteners at its inner end and extends to the outside of the placement box 21 at its outer end; the abutment plate 23 is fixedly installed on the inner side of the anti-blocking plate 22; the stabilizing plate 27 is vertically installed on the top of the placement plate 24; the abutment plate 23 is fixed to the inner side wall of the anti-blocking plate 22, and the stabilizing plate 27 is inserted into the vertical slot of the abutment plate 23, realizing the automatic state switching of "no-load locking - load clamping". When no load is applied, the stabilizing plate 27 is inserted into the slot of the abutment plate 23 to lock the position of the anti-blocking plate 22, and automatically releases the lock when under load.

[0048] This application provides a lifting device for electromechanical installation in a coal mine, which uses a hydraulic cylinder or a scissor lift platform to achieve vertical movement. A clamping and stabilizing mechanism 2 is fixedly installed on the top working surface of the lifting mechanism 1 to support and fix the electromechanical installation components. When the installation component is placed on the placement plate 24, the placement plate 24 descends. The descent of the placement plate 24 causes the stabilizing plate 27 to disengage from the slot of the abutment plate 23, releasing the lock on the anti-slip plate 22; pushing the anti-slip plate 22 clamps the installation component through the anti-slip pad 211. When the installation component is placed on the placement plate 24, the placement plate 24 descends along the positioning rod 25. The descent of the placement plate 24 causes the stabilizing plate 27 to disengage from the slot of the abutment plate 23, releasing the lock on the anti-slip plate 22; pushing the anti-slip plate 22 clamps the installation component. A sliding protective mechanism 3 is slidably connected to the top opening of the clamping and stabilizing mechanism 2, providing a loading and unloading channel while protecting the internal installation components.

[0049] Reference Figure 2-5As shown, in some embodiments, the clamping and stabilizing mechanism 2 further includes: a sleeve rod 28 installed on the outer wall of the placement box 21, the connecting rod 26 passing through the sleeve rod 28, and the outer end of the connecting rod 26 and the sleeve rod 28 cooperating to form an operating handle.

[0050] By setting a sleeve rod 28 on the outer wall of the placement box 21 and cooperating with the connecting rod 26 to form an operating handle, the sleeve rod 28 provides guiding support for the connecting rod 26, avoiding shaking or displacement during manual adjustment, and ensuring adjustment accuracy and structural stability.

[0051] Reference Figure 4 As shown, in some embodiments, the clamping stabilizing mechanism 2 further includes: a second return spring 212 sleeved on the positioning rod 25; one end of the second return spring 212 abuts against the placement plate 24, and the other end is fixed to the inner wall of the placement box 21, providing adaptive support force and automatically adjusting the elastic force according to the weight of the installation component.

[0052] The second return spring 212 is sleeved on the positioning rod 25. One end of the second return spring abuts against the placement plate 24 through an annular washer, and the other end is fixed to a spring seat on the inner wall of the placement box 21. When the placement plate 24 carrying the mounting component moves down, the spring is compressed and stores elastic potential energy; when unloaded, the spring returns to its original position, driving the placement plate 24 to return to its original position, ensuring that the stabilizing plate 27 is accurately inserted into the slot of the abutment plate 23.

[0053] Reference Figure 4 As shown, in some embodiments, the sleeve 28 is provided with a first return spring 29 sleeved on the connecting rod 26 to provide a stable clamping and returning force.

[0054] When the mounting component triggers clamping, the first reset spring 29 pushes the connecting rod 26 to move, which in turn drives the anti-clamping plate 22 to clamp smoothly, ensuring that the mounting component does not shift during transportation, while avoiding excessive clamping force that could damage the surface of the equipment.

[0055] Reference Figure 1 and 5 As shown, in some embodiments, the connecting rod 26 is provided with a radially protruding limiting disk 210, which slides in contact with the inner wall of the placement box 21 to limit the axial movement range of the connecting rod 26.

[0056] Link 26 provides guidance to prevent plate 22 from shifting and avoids tilting and jamming. Limiting plate 210 limits the maximum stroke of link 26 to ensure sufficient clamping stroke while preventing overload damage to the mounting components.

[0057] Reference Figure 4As shown, in some embodiments, the anti-slip pad 211 is provided on the opposite inner side of the anti-slip plate 22. The anti-slip pad 211 is embedded in the groove on the side of the anti-slip plate 22 to increase the static friction coefficient and improve the reliability of clamping.

[0058] The anti-slip mat has a diamond-shaped anti-slip texture on its surface, which can significantly increase the coefficient of friction and prevent the installation parts from sliding. At the same time, the elastic material protects the equipment installation parts from being scratched.

[0059] Reference Figure 1 and Figure 6 As shown, in some embodiments, the sliding protection mechanism 3 includes: a cover plate 31 fixedly installed on one side of the top of the placement box 21; and a placement plate 32 that slides horizontally on the other side of the top of the placement box 21, forming a sliding fit with the cover plate 31 to protect the installation parts; and adjusting blocks 33 symmetrically fixed on both sides of the placement plate 32 for adjusting the opening and closing size of the placement plate 32.

[0060] When the cover plate 31 and the placement plate 32 are closed, they form a complete top surface, effectively blocking debris such as gravel and coal blocks falling from the top of the coal mine roadway, and preventing surface damage or internal component failure of the installation parts due to impact; the adjustment block 33 can adjust the opening and closing range of the placement plate 32 to match different sized installation parts, and is suitable for installation parts of different sizes; it achieves multiple functions of protection, loading and unloading, and adaptive adjustment in a limited space, providing a reliable guarantee for the safe transportation of electromechanical installation parts in coal mines.

[0061] Reference Figure 1 and Figure 6 As shown, in some embodiments, the placement plate 32 is slidably connected to the guide hole in the adjusting block 33 via a horizontally arranged guide rod 34, ensuring that the placement plate 32 slides smoothly.

[0062] The placement plate 32, through its sliding connection with the adjusting block 33 and its tight engagement with the guide rod 34, enables rapid opening and closing in the horizontal direction. This design not only improves the ease of operation but also ensures the stability and accuracy of the placement plate 32 during use.

[0063] Reference Figure 1 and Figure 6 As shown, in some embodiments, the sliding protection mechanism 3 further includes a third return spring 35 sleeved on the guide rod 34; one end of the third return spring 35 abuts against the adjusting block 33, and the other end abuts against the cover plate 31, to ensure that the sliding protection mechanism 3 automatically and tightly closes.

[0064] When the operator releases the loading plate 32, the third return spring 35, due to its elastic deformation, drives the adjusting block 33 to slide along the guide rod 34, causing the loading plate 32 to quickly return to its original position. This ensures that the sliding protective mechanism 3 automatically closes without manual intervention, avoiding the risk of exposed components due to negligence in closing. During the operation of the lifting mechanism 1, the third return spring 35 can buffer the displacement of the loading plate 32 caused by vibration, absorbing impact energy through elastic deformation, preventing the protective plate from loosening or abnormally opening due to bumps, and ensuring the reliability of protection throughout the transportation process.

[0065] Reference Figure 1 As shown, in some embodiments, the bottom of the lifting mechanism 1 is equipped with several casters, which enable the lifting mechanism 1 to move easily on different surfaces, thereby improving the flexibility and ease of operation of the entire device.

[0066] The lifting mechanism 1 is equipped with four heavy-duty casters at its bottom. The casters employ a dual braking system, including rotation locking and directional locking, to ensure the stability of the lifting device during lifting. The wheel frame height is adjustable to adapt to uneven underground ground.

[0067] Based on the above technical features, the working principle of the lifting device for coal mine electromechanical installation provided in this application in actual application scenarios is as follows:

[0068] When the placement plate 24 is not carrying the mounting component, it is at its highest position under the elastic force of the second return spring 212. The stabilizing plate 27 at its top is precisely inserted into the vertical slot of the inner side of the anti-slip plate 22 against the plate 23, forming a mechanical lock. At this time, the anti-slip plate 22 is restricted from horizontal movement by the stabilizing plate 27, preventing accidental contact with the clamping mechanism and thus avoiding injury to the operator, while ensuring the stability of the internal structure of the device during movement or lifting. When the mounting component is placed on the placement plate 24, its weight exceeds the preload of the second return spring 212. The placement plate 24 slides downward along the positioning rod 25, compressing the second return spring 212 and storing elastic potential energy. The descent of the placement plate 24 causes the stabilizing plate 27 to move synchronously, disengaging it from the slot of the anti-slip plate 23 and releasing the mechanical lock on the anti-slip plate 22. After the lock is released, the first return spring 29, sleeved on the connecting rod 26, pushes the connecting rod 26 inward due to the preload, causing the anti-slip plate 22 to clamp the mounting component through the inner anti-slip pad 211. The spring force creates a stable clamping force, suppressing horizontal swaying of the mounting component. The operator pulls the placement plate 32, overcoming the force of the third return spring 35 to open the top opening, allowing the mounting component to be placed on or removed from the placement plate 24. After releasing the placement plate 32, the third return spring 35 drives it to quickly return to its original position along the slide rail, forming a closed structure with the cover plate 31 to prevent falling debris such as gravel and coal from impacting the mounting component.

[0069] It is readily understood that, based on the several embodiments provided in this application, those skilled in the art can combine, split, or reorganize the embodiments of this application to obtain other embodiments, none of which exceed the protection scope of this application.

[0070] The above detailed embodiments further illustrate the purpose, technical solution, and beneficial effects of the embodiments of this application. It should be understood that the above are merely specific embodiments of the embodiments of this application and are not intended to limit the protection scope of the embodiments of this application. Any modifications, equivalent substitutions, improvements, etc., made on the basis of the technical solutions of the embodiments of this application should be included within the protection scope of the embodiments of this application.
