It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.
[0036] See also Figure 1-6 As shown, according to an embodiment of the present application, a mounting and fixing device for a ladder beam in an underground mine is provided, wherein the mounting and fixing device 1 is arranged between an inner wall of a mine 2 and a ladder beam 3, and the mounting and fixing device 1 comprises:
[0037] A bracket 11, wherein a plurality of brackets 11 are symmetrically arranged in pairs on the inner wall of the mine 2, and the brackets 11 are used to support the ladder beam 3;
[0038] The fixing component 12 is disposed on the bracket 11 , and the fixing component 12 surrounds and fastens the ladder beam 3 on the bracket 11 .
[0039] The installation and fixing device of the underground mine ladder beam provided in this embodiment is used to fix the ladder beam 3 on the inner wall of the mine 2. A plurality of brackets 11 are firmly attached to the inner wall of the mine 2 in a two-by-two symmetrical layout. The material thereof is a high-strength, corrosion-resistant metal material, such as high-quality alloy steel, to ensure that the ladder beam 3 and the weight of the personnel and equipment borne by it can be stably carried, and to resist the erosion and impact of the complex and harsh environment in the mine 2. The surface of the bracket 11 is specially treated, such as anti-corrosion coating and anti-slip texture treatment, which not only prolongs the service life of the bracket 11, but also ensures the stability of the placement of the ladder beam 3.
[0040] The fixing assembly 12 is arranged on the bracket 11, and can encircle and fasten the ladder beam 3 on the bracket 11. The fixing assembly 12 can adopt a clamp or a sleeve structure made of high-strength metal material, and its internal shape is highly consistent with the outer contour of the ladder beam 3, ensuring that there is no loose gap during the clamping process. During installation, the fixing assembly 12 is installed on the bracket 11 and closely matched with the ladder beam 3, ensuring that the connection between the fixing assembly 12 and the bracket 11 and between the fixing assembly 12 and the ladder beam 3 is stable and reliable, effectively preventing the ladder beam 3 from being displaced or falling off due to vibration, impact and other factors during use, thereby providing a solid guarantee for the safe operation of the ladder room of the mine 2, greatly improving the safety and reliability of the mine 2 operators passing through the ladder room, reducing the risk of safety accidents caused by the installation and fixing of the ladder beam 3, meeting the strict requirements for the installation and fixing of the ladder beam 3 in the complex environment of the underground mine 2, and improving the stability and safety of the entire mine 2 facilities.
[0041] The bracket 11 is symmetrically provided with mounting holes 13 , and the fixing assembly 12 is disposed on the bracket 11 through the mounting holes 13 .
[0042] In this technical solution, the symmetrically arranged mounting holes 13 on the bracket 11 provide an accurate and stable positioning basis for the installation of the fixing assembly 12. The symmetrical distribution of the mounting holes 13 ensures that the fixing assembly 12 can evenly apply a locking force to the ladder beam 3 after installation, so that the ladder beam 3 is subjected to a balanced force, and local deformation or displacement caused by uneven force is effectively prevented. The inner wall of the mounting hole 13 is finely processed and has good smoothness and verticality, which reduces the friction resistance of the fixing assembly 12 during the installation process, and at the same time ensures that the fixing assembly 12 will not be worn or fatigued during long-term use due to the unevenness of the mounting hole 13.
[0043] The fixing assembly 12 comprises:
[0044] A clamping ring 121, wherein the clamping ring 121 passes through the mounting hole 13 and is disposed on the bracket 11, and a limiting space for fixing the ladder beam 3 is formed between the clamping ring 121 and the bracket 11;
[0045] The fastener 122 is disposed on the retaining ring 121 , and the fastener 122 is located below the bracket 11 .
[0046] In this technical solution, the clamping ring 121 is made of a metal material with high strength and certain flexibility, such as high-quality alloy steel or spring steel. The clamping ring 121 is arranged on the bracket 11 through the mounting hole 13, and its shape is adapted to the shape of the ladder beam 3. When the clamping ring 121 is installed in place, a limiting space for fixing the ladder beam 3 is cleverly formed between the clamping ring 121 and the bracket 11. The limiting space can tightly wrap the ladder beam 3, so that the ladder beam 3 is reliably constrained in both the vertical and horizontal directions, and effectively prevents it from displacement or shaking.
[0047] The fastener 122 is arranged on the clamp ring 121 and is located below the bracket 11, and it can adopt a threaded connection structure or a buckle structure. If it is a threaded connection structure, the bottom of the clamp ring 121 passes through the mounting hole 13 and is located below the bracket 11 and is threadedly connected with the fastener 122. The clamping force of the clamp ring 121 on the ladder beam 3 is adjusted by tightening the fastener 122 to ensure that a stable fixing effect can be achieved under different working conditions. During the installation process, the clamp ring 121 is first passed through the mounting hole 13 and placed above the ladder beam 3, and then the fastener 122 is installed on the clamp ring 121 and tightened. The fixing assembly 12 can efficiently encircle and buckle the ladder beam 3 and fix it on the bracket 11. Even in the complex and harsh environment of the mine 2, such as frequent vibrations, humid air, and possible ore impacts, the ladder beam 3 can still be stably fixed, which greatly improves the reliability and safety of the ladder beam 3 installation and fixing device 1, and provides a solid guarantee for the safe passage of the underground mine 2 operators between the ladders.
[0048] The snap ring 121 comprises:
[0049] Arc segment 1211;
[0050] The connecting section 1212 is arranged in parallel on both sides of the arc section 1211 , and the connecting section 1212 passes through the mounting hole 13 to be connected with the fastener 122 .
[0051] In this technical solution, the clamping ring 121 includes an arc segment 1211 and a connecting segment 1212. The arc segment 1211 can be adapted to the outer contour of the ladder beam 3 and can be more evenly fitted on the surface of the ladder beam 3, ensuring that the maximum area of contact with the ladder beam 3 is achieved during the fixing process, thereby effectively dispersing the clamping force and preventing damage to the ladder beam 3 due to excessive local pressure. The arc segment 1211 is made of a high-strength, wear-resistant and corrosion-resistant metal material, such as stainless steel or alloy structural steel, to ensure that it can withstand the test of the harsh environment of the mine 2 during long-term use and maintain good clamping performance.
[0052] The connecting section 1212 is arranged in parallel on both sides of the arc section 1211, and the connecting section 1212 passes through the mounting hole 13 and is connected to the fastener 122. The length of the connecting section 1212 meets the thickness of the bracket 11 and the installation requirements of the fastener 122, ensuring that the clamping ring 121 can be stably fixed on the bracket 11 after installation, and the ladder beam 3 can be reliably held by the fastener 122. The connecting section 1212 and the arc section 1211 are connected by integrated molding or high-strength welding technology to ensure the structural strength and integrity of the entire clamping ring 121, and prevent the connection part from breaking or loosening during use. During installation, first pass the connecting section 1212 through the mounting hole 13 on the bracket 11, then place the ladder beam 3 at a suitable position on the bracket 11, and then fit the arc section 1211 of the retaining ring 121 onto the ladder beam 3, and finally fasten the connecting section 1212 through the fastener 122, so that a stable limiting space is formed between the retaining ring 121 and the bracket 11, and the ladder beam 3 is firmly fixed, thereby improving the reliability and stability of the ladder beam 3 after installation, reducing the safety hazards caused by the loose fixation of the ladder beam 3, meeting the requirements for the installation and fixation of the ladder beam 3 in the complex environment of the mine 2, and ensuring the life safety and working efficiency of the operators.
[0053] The fastener 122 and the connecting section 1212 are detachably connected.
[0054] In this technical solution, the fastener 122 and the connecting section 1212 are connected in a detachable manner to improve the convenience of installation, maintenance and adjustment between the two. The detachable connection can be achieved by the combination of bolts and nuts. The connecting section 1212 is provided with an external thread, and the fastener 122 is provided with an internal thread. The fastener 122 can be easily connected or separated from the connecting section 1212 by tightening or loosening the fastener 122.
[0055] When in use, the operator can first pass the connecting section 1212 of the clamp ring 121 through the mounting hole 13 of the bracket 11, and then install the fastener 122 on the connecting section 1212 and perform the fastening operation, which is convenient for operation in the narrow space of the mine 2 and improves the installation efficiency. During the maintenance of the device, when the fastener 122 needs to be inspected, replaced or repaired, it can be easily removed from the connecting section 1212 without the need to perform complicated disassembly operations on the entire clamp ring 121 or the bracket 11, thereby reducing maintenance costs and time.
[0056] In addition, when the specifications or installation position of the ladder beam 3 need to be adjusted, the detachable connection method also allows the fastener 122 to be quickly removed and reinstalled so as to adjust the clamping force or position of the clamping ring 121, which can better adapt to different ladder beams 3 and mine 2 environmental requirements and enhance the flexibility and versatility of the device.
[0057] The mounting hole 13 is a strip-shaped hole.
[0058] The length of the mounting hole 13 is greater than the diameter of the connecting section 1212 .
[0059] In this technical solution, by providing the mounting hole 13 as a strip-shaped hole and the length of the mounting hole being greater than the diameter of the connecting section 1212 , a significant error tolerance space is provided for the installation.
[0060] During the construction of the mine 2, due to the complex and changeable conditions of the shaft wall and the limitation of construction accuracy, the installation position of the bracket 11 may have a certain deviation. The existence of the strip hole allows the connecting section 1212 to be adjusted to a certain extent within the length range of the strip hole when passing through the installation hole 13, thereby effectively compensating for the inaccuracy of the installation position of the bracket 11 and ensuring that the clamping ring 121 can accurately encircle and fasten the ladder beam 3. Even if the bracket 11 is slightly misaligned during installation, there is no need to re-drill the bracket 11 or perform other complicated adjustment operations, which greatly reduces the difficulty of installation and improves the installation efficiency.
[0061] At the same time, the arrangement of the strip hole also facilitates the later maintenance and adjustment of the ladder beam 3. For example, when the ladder beam 3 is slightly deformed due to long-term use or needs to be fine-tuned, the fixing state of the clamping ring 121 on the ladder beam 3 can be readjusted by appropriately moving the position of the connecting section 1212 in the strip hole, without the need to perform large-scale disassembly and reorganization of the entire installation and fixing device 1, which significantly enhances the adaptability to the complex environment of the mine 2 and the dynamic changes of the ladder beam 3, effectively ensures the safe and stable fixation of the ladder beam 3 in the mine 2, and reduces the potential safety hazards caused by installation errors, deformation and other factors.
[0062] A locking assembly 14 is provided between the bracket 11 and the inner wall of the mine 2 , for fixing the bracket 11 on the inner wall of the mine 2 .
[0063] The locking assembly 14 comprises:
[0064] A locking plate 141, wherein the locking plate 141 is provided with a plurality of locking holes;
[0065] An anchor rod 142 , wherein the anchor rod 142 passes through the locking hole and is connected to the inner wall of the mine 2 .
[0066] In this technical solution, a locking assembly 14 is installed between the bracket 11 and the inner wall of the mine 2. The locking plate 141 is made of high-strength, corrosion-resistant metal material, such as high-quality alloy steel. A number of locking holes are evenly opened on the locking plate 141. The anchor rod 142 passes through the locking hole and is connected to the inner wall of the mine 2. The anchor rod 142 can be made of high-strength anchor material, such as a threaded steel anchor rod. Its length is determined according to the thickness of the wall of the mine 2 and the required anchoring depth, ensuring that it can penetrate deep enough into the wall of the mine 2 to provide reliable anchoring force. During installation, the locking plate 141 is first attached to the contact portion between the bracket 11 and the inner wall of the mine 2, and then the anchor rod 142 is passed through the locking hole and driven into the inner wall of the mine 2. The bracket 11 is firmly fixed on the inner wall of the mine 2 through the friction between the anchor rod 142 and the inner wall of the mine 2 and the pull-out resistance of the anchor rod 142 itself. The setting of the locking assembly 14 can effectively resist various forces in the complex and harsh environment of the mine 2, such as vibration, impact and formation pressure, and prevent the bracket 11 from loosening or displacement, thereby ensuring the stability and safety of the installation of the ladder beam 3, providing a solid foundation for the safe passage of workers in the underground mine 2 between ladders, and greatly reducing the risk of safety accidents caused by loose fixation of the bracket 11.
[0067] At least two fixing components 12 are disposed on the bracket 11 .
[0068] In this technical solution, at least two fixing components 12 provided on the bracket 11 improve the reliability and stability of fixing the ladder beam 3. The multiple fixing components 12 are reasonably arranged on the bracket 11, for example, they can be evenly distributed along the length direction of the ladder beam 3, or they can be arranged at key positions according to the stress characteristics of the ladder beam 3.
[0069] Each fixing component 12 can independently apply a circumferential locking force to the ladder beam 3, and multiple fixing components 12 work together to form a stable structure with multiple fixed points. In the complex environment of the mine 2, when subjected to external forces such as vibration, impact, and ore collision, multiple fixing components 12 can evenly disperse these external forces to avoid the ladder beam 3 from loosening or falling off due to excessive force on a single point. At the same time, the setting of multiple fixing components 12 also provides more adjustment flexibility for the installation of the ladder beam 3. During the installation process, if there is a slight deviation in the cooperation between a certain fixing component 12 and the ladder beam 3, it can be compensated by adjusting other fixing components 12 to ensure the accuracy and quality of the overall installation. Through the effective setting of at least two fixing components 12, the fixing performance of the ladder beam 3 is further enhanced, the risk of safety accidents is effectively reduced, and the reliability of the entire mine 2 facilities is improved.

Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application. The above are only preferred implementations of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and variations can be made without departing from the technical principles of the present application, and these improvements and variations should also be regarded as the protection scope of the present application.
