Description

Technical Field

[0001] This utility model relates to the field of coal mine equipment technology, specifically to a fully mechanized mining face support retraction platform. Background Technology

[0002] Modern coal mining requires the use of various equipment. In the complete set of equipment for fully mechanized mining faces, there are many hydraulic supports, which are large in size and weight. In the fully mechanized mining process of working faces with complex geology, the length of the working face is shortened due to changes in the dip angle of the coal seam or other reasons, making it difficult to place the equipment. Therefore, it is necessary to withdraw the excess hydraulic supports.

[0003] A fully mechanized mining face support retraction platform is a piece of equipment used in fully mechanized mining faces to improve coal mining efficiency and face safety. This type of support is typically designed to quickly retract hydraulic supports to the next mining area for the next round of mining.

[0004] The currently used support retraction platform must rely on external traction equipment during movement; the platform's displacement can only be achieved through the power output of the traction equipment.

[0005] However, the traction support of the support retraction platform is directly fixed to the base, and its height remains constant. This fixed design cannot be flexibly adjusted according to the actual working height of the traction equipment during on-site operations, resulting in an imperfect connection and coordination between the traction equipment and the platform. In actual operation, this height mismatch severely affects the effective traction of the platform by the external traction equipment, not only increasing the difficulty of operation but also easily causing instability during the traction process. Ultimately, this reduces the overall efficiency of the hydraulic support retraction operation and increases working time and labor costs.

[0006] Therefore, we propose a fully mechanized mining face support retraction platform to solve the above problems. Utility Model Content

[0007] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a fully mechanized mining face support retraction platform, which solves the problems mentioned in the background section.

[0008] (II) Technical Solution To achieve the above objectives, this utility model specifically adopts the following technical solution: A fully mechanized mining face support retraction platform includes a retraction platform structure, an adjustable traction structure is provided on the front side of the retraction platform structure, and the retraction platform structure is connected to a traction device through the adjustable traction structure. The adjustable traction structure includes a connecting block, a rotating frame hinged to the front side of the connecting block, a splicing block hinged to the front side of the rotating frame, a damping spring rod provided on the inner side of the splicing block, and a connecting ring fixedly installed at the front end of the damping spring rod extending to the outer side of the splicing block.

[0009] Furthermore, the retraction platform structure includes an installation frame, on the front side of which a connecting platform is fixedly installed, and the front side of the connecting platform is connected to the back side of the connecting block.

[0010] Furthermore, an external frame is fixedly installed on the side wall of the mounting frame, and a conveyor wheel is rotatably connected to the inner side of the external frame. The conveyor wheel is connected to the ground or track of the tunnel.

[0011] Furthermore, a synchronous hydraulic cylinder is provided at the end of the mounting frame, and a conveying plate is hinged to the movable end of the synchronous hydraulic cylinder. A lifting rod is fixedly installed at the end of the mounting frame, and the lifting rod is located below the conveying plate.

[0012] Furthermore, a placement platform is movably attached to the top of the mounting frame, and an anti-slip pad is provided on the top of the placement platform.

[0013] Furthermore, a hinge seat is provided at the top of the connecting block, and a linkage rod is rotatably connected to the surface of the hinge seat. The other end of the linkage rod is rotatably connected to the inner wall of the splicing block.

[0014] Furthermore, a reinforcing bolt is fixedly inserted into the inner side of the rotating frame, and the side end of the reinforcing bolt is connected to the outer wall of the rotating frame through a locking pin.

[0015] Furthermore, a top cover is movably attached to the top of the splicing block, and the damping spring rod is located below the top cover.

[0016] (III) Beneficial Effects Compared with the prior art, this utility model provides a fully mechanized mining face support retraction platform, which has the following beneficial effects: This invention utilizes an adjustable traction structure. Through the interlocking of connecting blocks, rotating frames, and splicing blocks, the retraction platform structure can be connected to the traction equipment via a connecting ring.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0020] like Figure 1-5 As shown in the figure, an embodiment of the present invention provides a fully mechanized mining face support retraction platform, including a retraction platform structure 1, an adjustable traction structure 2 is provided on the front side of the retraction platform structure 1, and the retraction platform structure 1 is connected to the traction equipment through the adjustable traction structure 2.

[0021] The adjustable traction structure 2 includes a connecting block 201, a rotating frame 202 is hinged to the front side of the connecting block 201, a splicing block 203 is hinged to the front side of the rotating frame 202, a damping spring rod 208 is provided on the inner side of the splicing block 203, and the front end of the damping spring rod 208 extends to the outer side of the splicing block 203 and is fixedly installed with a connecting ring 209.

[0022] The design of the damping spring rod 208 takes into account its cooperation with the connecting ring 209. As the part directly connected to the traction equipment, the connecting ring 209 needs to withstand a large traction force. Through its elastic deformation, the damping spring rod 208 can provide a certain buffering effect when the connecting ring 209 is subjected to traction force, thereby protecting the connecting ring 209 and the entire adjustable traction structure 2 from damage.

[0023] like Figure 2 As shown, in some embodiments, the retraction platform structure 1 includes an installation frame 101, on the front side of which a connecting platform 102 is fixedly installed, and the front side of the connecting platform 102 is connected to the back side of the connecting block 201.

[0024] Specifically, the installation frame 101 serves as the foundation of the entire retraction platform structure 1, and its stability and load-bearing capacity are of paramount importance.

[0025] The design of the connecting platform 102 ensures a stable connection between the adjustable traction structure 2 and the retraction platform structure 1, so that the force can be evenly transmitted during the traction process, avoiding structural damage caused by excessive local stress.

[0026] like Figure 2 As shown, in some embodiments, an external frame 103 is fixedly installed on the side wall of the mounting frame 101, and a conveyor wheel 104 is rotatably connected to the inner side of the external frame 103. The conveyor wheel 104 is connected to the ground or track of the tunnel.

[0027] Specifically, the rotating connection of the conveyor wheels 104 allows the retraction platform to adaptively adjust to the undulations and slopes of the ground during movement, thus maintaining the platform's stability. This design not only reduces platform bumps and vibrations during movement but also minimizes damage to the tunnel floor and extends the tunnel's service life.

[0028] Meanwhile, the fixed installation of the external frame 103 provides stable support for the conveyor wheel 104, ensuring that the conveyor wheel 104 can maintain stable rotation when bearing the weight of the retraction platform and its load, without falling off or getting stuck. This stable design is crucial to ensuring the safety and reliability of the retraction platform during movement.

[0029] like Figure 2 As shown, in some embodiments, a synchronous hydraulic cylinder 105 is provided at the end of the mounting frame 101, and a conveying plate 106 is hinged to the movable end of the synchronous hydraulic cylinder 105. A lifting rod 107 is fixedly installed at the end of the mounting frame 101, and the lifting rod 107 is located below the conveying plate 106.

[0030] Specifically, the synchronous hydraulic cylinder 105 is powered by the hydraulic system and can precisely control the lifting height and speed of the conveyor plate 106. This precise control allows the position of the conveyor plate 106 to be adjusted according to actual needs when unloading heavy equipment such as hydraulic supports, thereby ensuring a smooth and safe unloading process.

[0031] The design of the lifting rod 107 further enhances safety during the unloading process. When the conveyor plate 106 carries heavy equipment, the lifting rod 107 can provide additional support to prevent the conveyor plate 106 from deforming or being damaged due to excessive load.

[0032] Meanwhile, the position of the lifting rod 107 below the conveyor plate 106 ensures that it provides support without interfering with the normal lifting and lowering of the conveyor plate 106.

[0033] Furthermore, the combined design of the synchronous hydraulic cylinder 105 and the lifting rod 107 gives the retraction platform greater flexibility when unloading equipment. Whether rapid unloading or precise adjustment of equipment position is required, this design meets practical needs, improving the working efficiency and applicability of the retraction platform.

[0034] like Figure 2 As shown, in some embodiments, the top of the mounting frame 101 is movably connected to a placement platform 108, and the top of the placement platform 108 is provided with an anti-slip pad.

[0035] Specifically, the movable snap-fit ​​design of the placement platform 108 allows for quick installation or disassembly according to actual work needs. When hydraulic support retraction is required, the placement platform 108 can be quickly installed onto the mounting frame 101, providing workers with a stable and safe working environment. After the work is completed, it can be easily disassembled for convenient movement and storage.

[0036] The anti-slip pads installed at the top of the platform 108 are to further improve the safety of the hydraulic support on the platform.

[0037] The anti-slip mat is made of soft silicone grease, providing excellent anti-slip performance and wear resistance. During the placement of the hydraulic support, even if the platform is subjected to vibration or tilting, the anti-slip mat can effectively prevent the support from sliding or shifting, thus ensuring the safety of the hydraulic support.

[0038] like Figure 3 As shown, in some embodiments, the top end of the connecting block 201 is provided with a hinge seat 204, and the surface of the hinge seat 204 is rotatably connected to a linkage rod 205, the other end of the linkage rod 205 being rotatably connected to the inner wall of the splicing block 203.

[0039] Specifically, the hinge seat 204 is designed to provide a stable center of rotation for the linkage rod 205, allowing the linkage rod 205 to rotate flexibly between the connecting block 201 and the splicing block 203.

[0040] This rotating connection not only enhances the overall flexibility of the adjustable traction structure 2, but also enables smoother force transmission between components during traction, avoiding structural damage or traction failure caused by poor force transmission.

[0041] During the traction process, the linkage 205 can automatically adjust its angle with the splicing block 203 according to the direction and magnitude of the traction force, thereby ensuring the uniform transmission of the traction force.

[0042] At the same time, this rotating connection method also allows the linkage rod 205 to distribute the force through slight angle adjustments when subjected to large traction forces, thus avoiding breakage or deformation caused by excessive local stress.

[0043] like Figure 3 As shown, in some embodiments, a reinforcing bolt 206 is fixedly inserted into the inner side of the rotating frame 202, and the side end of the reinforcing bolt 206 is connected to the outer wall of the rotating frame 202 by a locking pin.

[0044] Specifically, the insertion of the reinforcing bolt 206 provides additional structural support for the rotating frame 202, effectively enhancing its load-bearing capacity and stability. When the rotating frame 202 is subjected to complex force systems from the traction equipment and the retraction platform structure 1, the reinforcing bolt 206 can distribute and bear part of the force, thereby preventing the rotating frame 202 from deforming or being damaged due to uneven force distribution.

[0045] Meanwhile, the design of the locking pin makes the connection between the reinforcing bolt 206 and the rotating frame 202 more secure and reliable. During traction, even if a large impact or vibration is encountered, the locking pin can ensure that the reinforcing bolt 206 will not fall off or shift, thereby ensuring the overall stability and safety of the adjustable traction structure 2.

[0046] like Figure 3 As shown, in some embodiments, the top of the splicing block 203 is movably latched to the top cover 207, and the damping spring rod 208 is located below the top cover 207.

[0047] Specifically, the movable snap-fit ​​design of the top cover 207 provides a convenient access for the maintenance and replacement of the damping spring rod 208. When the damping spring rod 208 needs to be repaired or replaced due to prolonged use or significant impact, the top cover 207 can be easily removed to access the damping spring rod 208 without disassembling the entire adjustable traction structure 2.

[0048] The damping spring rod 208 is located below the top cover 207. This layout not only protects the damping spring rod 208 from direct corrosion from the external environment, such as dust and moisture, but also ensures that it can fully exert its damping effect during operation.

[0049] When the hydraulic support needs to be retracted during use, the operator will first adjust the height of the adjustable traction structure 2 by adjusting the angle relationship between the rotating frame 202 and the connecting block 201 and the splicing block 203 according to the actual working height of the traction equipment.

[0050] During this process, the linkage rod 205 will rotate flexibly under the support of the hinge seat 204, ensuring smoothness and stability of the adjustment. At the same time, the combination design of the reinforcing bolt 206 and the locking pin provides reliable structural support for the rotating frame 202, avoiding structural damage caused by uneven force during the adjustment process.

[0051] Once the height of the adjustable traction structure 2 is matched with the traction equipment, the operator will connect the traction end of the traction equipment to the connecting ring 209.

[0052] At this point, the damping spring rod 208 begins to function, providing a certain degree of cushioning during traction and reducing the impact of the traction force on the connecting ring 209 and the entire adjustable traction structure 2. This design not only protects the equipment from damage but also improves the smoothness and safety of the traction process.

[0053] Next, the traction equipment is activated, and the adjustable traction structure 2 drives the retraction platform structure 1 to move. During the movement, the conveyor wheels 104 adaptively adjust according to the undulations and slopes of the ground to maintain the stability of the platform. At the same time, the combined design of the synchronous hydraulic cylinder 105 and the lifting rod 107 allows for precise adjustment of the position of the conveyor plate 106 according to actual needs when unloading heavy equipment such as hydraulic supports, ensuring a smooth and safe unloading process.

[0054] Once the hydraulic support is safely unloaded to the designated position, the operator will move the retraction platform structure 1 to the next working point to continue the retraction operation of the hydraulic support.

[0055] In summary, by using the adjustable traction structure 2, the interconnection of the connecting block 201, rotating frame 202, and splicing block 203 allows the retraction platform structure 1 to be connected to the traction equipment via the connecting ring 209. Furthermore, the rotating frame 202 creates a height difference between the connecting block 201 and the splicing block 203, enabling flexible adjustment based on the actual working height of the traction equipment. This effectively solves the problem of unsatisfactory connection caused by a fixed traction support height in existing technologies. This results in a tighter and more stable connection between the traction equipment and the retraction platform structure 1, reducing operational difficulty and minimizing instability during the traction process.

[0056] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
