Description

Technical Field

[0001] This utility model relates to the field of coal mine auxiliary loading and unloading technology, and in particular to an adaptive buffer coal mine auxiliary transportation material loading and unloading platform. Background Technology

[0002] With the expansion of coal mining scale and the improvement of mechanization, higher requirements are placed on the efficiency, safety, and flexibility of material transportation. Traditional material loading and unloading platforms often have a simple structure, making it difficult to adapt to the transportation needs of different types and shapes of materials. They lack buffering and adaptive mechanisms, which can easily cause material damage or equipment failure during transportation. In addition, traditional material loading and unloading platforms are complex to operate, requiring frequent manual adjustments and operations, which affects transportation efficiency.

[0003] Chinese Patent CN220283517U discloses a material unloading lift, which uses a lifting assembly, a storage hopper, a push plate, and a first linear displacement mechanism to vertically transport materials. The first linear displacement mechanism drives the push plate to push the material out of the storage hopper and into a transport vehicle, eliminating the need for manual unloading and avoiding the time and labor costs of manual unloading, thus reducing the cost of material loading and unloading. However, in the case of coal mine materials lacking a buffer mechanism and slow equipment unloading efficiency during transportation, problems such as material and equipment damage and impact on the overall transportation progress may occur. In view of this, an adaptive buffer-type coal mine auxiliary transportation material loading and unloading platform is provided. Utility Model Content

[0004] The main purpose of this utility model is to provide an adaptive buffer-type auxiliary transportation material loading and unloading platform for coal mines, so as to solve the problems mentioned in related technologies, such as the lack of buffering mechanisms and slow equipment unloading efficiency during the transportation of coal materials, resulting in material and equipment damage and affecting the overall transportation progress.

[0005] To achieve the above objectives, according to one aspect of the present invention, an adaptive buffer-type auxiliary transportation material loading and unloading platform for coal mines is provided, comprising a cross-type lifting mechanism slidably mounted on a slide rail, a platform plate being provided above the cross-type lifting mechanism, a fixed frame being fixedly mounted on the platform plate, a buffer part being provided at the lower end of the fixed frame, a base plate being fixedly connected to the buffer part, and the base plate being slidably mounted within the fixed frame, the base plate having several grooves, each groove having several ball bearings rotatably mounted therein, and an opening and closing door being provided on one side of the fixed frame.

[0006] Furthermore, the buffer section includes two symmetrically arranged buffer pads, with several springs fixedly connected between the buffer pads, and the lower buffer pad is fixedly connected to the platform plate.

[0007] Furthermore, a side plate is fixedly connected to the base plate, the groove is U-shaped, the ball bearing is rotatably disposed at the upper end of the groove, and the lower end of the groove is used to receive broken materials.

[0008] Furthermore, a slot is provided on the inner side of the fixed frame, and a sliding groove communicating with the slot is also provided in the fixed frame, and the side plate is slidably installed in the sliding groove.

[0009] Furthermore, the opening and closing door includes an upper door and a lower door, and the inner wall of the lower door is fixedly provided with several diversion strips with different inclination angles.

[0010] Furthermore, limit frames are provided on both sides of the fixed frame, baffles are slidably arranged inside the limit frames, and two screws are threadedly installed at both ends of the limit frames.

[0011] Furthermore, the cross-type lifting mechanism includes at least a support plate, a cylinder is fixedly mounted on one end of the support plate, a first connecting block is fixedly mounted on one end of the bottom of the platform plate, a second connecting block is hinged on the first connecting block, and the output shaft of the cylinder is fixedly connected to the second connecting block.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. In this adaptive buffer-type coal mine auxiliary transportation material loading and unloading platform, ball bearings are rotatably installed in the grooves opened on the bottom plate. These ball bearings can provide rolling support when the material moves, reducing the frictional resistance between the material and the bottom plate. This not only promotes the smooth unloading of the material, but also reduces the wear of the bottom plate and extends the service life of the platform. At the same time, the lower end of the groove is used to receive broken materials, avoiding the accumulation of broken materials on the bottom plate and keeping the platform clean.

[0014] 2. In this adaptive buffer-type coal mine auxiliary transportation material loading and unloading platform, the buffer part consists of two symmetrically arranged buffer pads and several springs, which can significantly absorb and disperse the local impact force on the bottom plate. When materials are loaded, especially heavy or irregularly shaped materials, the bottom plate may be subjected to uneven forces. The combination of buffer pads and springs can quickly restore the shape and absorb energy, preventing the platform from overturning due to local heavy load, thereby protecting the bottom plate and the entire loading and unloading platform from damage.

[0029] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0030] Please see Figures 1-8As shown, the purpose of this embodiment is to provide an adaptive buffer-type auxiliary transportation material loading and unloading platform for coal mines, including a cross-type lifting mechanism 1 that is slidably installed on a slide rail. A platform plate 2 is provided above the cross-type lifting mechanism 1. A fixed frame 3 is fixedly installed on the platform plate 2. A buffer part 5 is provided at the lower end of the fixed frame 3. A bottom plate 4 is fixedly connected to the buffer part 5. The bottom plate 4 is slidably installed in the fixed frame 3. Several grooves 42 are provided on the bottom plate 4. Several balls 43 are rotatably installed in each groove 42. An opening and closing door 31 is provided on one side of the fixed frame 3.

[0031] The buffer section 5 includes two symmetrically arranged buffer pads 51, with several springs 52 fixedly connected between them. The lower buffer pad 51 is fixedly connected to the platform plate 2, and the upper buffer pad 51 is fixedly connected to the base plate 4. The buffer pads 51 are preferably made of rubber to ensure that they can quickly recover their shape and absorb energy when impacted. The springs 52 serve to connect and support the buffer pads 51. When the base plate 4 is subjected to local impact force, the springs 52 can undergo elastic deformation, thereby absorbing and dispersing the impact force and preventing overturning due to local heavy load during the loading process. When loading material into the fixed frame 3, the base plate 4 may be subjected to local impact force. The upper buffer pad 51 is impacted first, and then this impact force is transmitted to the lower buffer pad 51 through the springs 52. During this process, the springs 52 undergo elastic deformation, absorbing most of the impact force, thereby protecting the base plate 4 and the entire loading and unloading platform from damage.

[0032] A side plate 41 is fixedly connected to the base plate 4. The side plate 41 is located at the edge of the upper surface of the base plate 4. The groove 42 is U-shaped. The ball bearing 43 is rotatably disposed at the upper end of the groove 42, and the upper end of the ball bearing 43 extends out of the groove 42, that is, it is higher than the height of the upper surface of the base plate 4, so that the ball bearing 43 can directly contact the material and provide rolling support when the material moves. The lower end of the groove 42 is used to receive broken material.

[0033] A slot 32 is provided on the inner side of the fixed frame 3. The bottom plate 4 and the buffer part 5 are located in the slot 32. A sliding groove 33 communicating with the slot 32 is also provided in the fixed frame 3. The side plate 41 is slidably installed in the sliding groove 33 to prevent material from entering the connection between the bottom plate 4 and the fixed frame 3 when the bottom plate 4 and the buffer part 5 slide down under force, thereby reducing potential safety hazards caused by material accumulation.

[0034] The opening and closing door 31 includes an upper door 311 and a lower door 312, which are connected to the fixed frame 3 by hinges to achieve flexible opening and closing. The inner wall of the lower door 312 is fixedly provided with several diversion strips 3121 with different inclination angles, and the inclination angle of the diversion strips 3121 is 0 to 90°. During the unloading process, the lower door 312 can be placed on the transport vehicle compartment to form an inclined unloading port. At this time, the diversion strips 3121 play the role of guiding the flow of materials and dispersing the materials to different areas of the compartment, thereby achieving a more uniform unloading effect.

[0035] To prevent materials from sliding off both sides of the lower door 312 during unloading, a limit frame 34 is provided on both sides of the fixed frame 3. A baffle 35 is slidably installed inside the limit frame 34. Two screws 36 are threaded on both ends of the limit frame 34, and two matching screw holes are opened at both ends of the top of the baffle 35. During unloading, the baffle 35 slides outward to block both sides of the lower door 312. The baffle 35 is fixed by threading the screws 36 into the screw holes and tightening them.

[0036] The cross-lift mechanism 1 utilizes a cross-shaped frame design, combining vertical lifting and horizontal telescopic drive to achieve the lifting and lowering of the support platform. Initially, the vertical lifting device raises the support platform to a certain height, avoiding mechanical dead spots; subsequently, the telescopic drive device drives the connecting rod to slide, causing the fork-shaped frame to extend and retract vertically, thus driving the support platform to continue lifting and lowering. The entire process is stable and efficient, suitable for various scenarios such as cargo handling and warehousing.

[0037] The cross-type lifting mechanism 1 includes at least a support plate 11. A cylinder 12 is fixedly installed on one end of the support plate 11. A first connecting block 21 is fixedly installed on one end of the bottom of the platform plate 2. A second connecting block 22 is hinged to the first connecting block 21, and the output shaft of the cylinder 12 is fixedly connected to the second connecting block 22. Similarly, two first connecting blocks 21 are symmetrically fixedly installed on the other end of the bottom of the platform plate 2, and two second connecting blocks 22 are symmetrically fixedly installed on the other end of the support plate 11, and the first connecting block 21 and the second connecting block 22 are hingedly connected.

[0038] During unloading, the platform plate 2 needs to be tilted to pour the material out through the opening and closing door 31. The output shaft of the cylinder 12 extends to push the second connecting block 22, which is fixedly connected to it. Since the first connecting block 21 and the second connecting block 22 are hinged, the first connecting block 21 will rotate relative to the second connecting block 22, thereby causing one end of the platform plate 2 to rise, thus tilting the platform plate 2 as a whole. At this time, the opening and closing door 31 is opened so that the lower door 312 rests on the transport vehicle compartment. Under the action of gravity, the material slides down the platform plate 2 and the opening and closing door 31 into the compartment. The ball bearings 43 on the bottom plate 4 can rotate freely with the movement of the material, thereby reducing the frictional resistance between the material and the bottom plate 4, further promoting the smooth unloading of the material. The broken material at the bottom of the groove 42 is poured out due to the tilt of the bottom plate 4, avoiding the accumulation of broken material on the bottom plate 4, and maintaining the cleanliness of the platform and the integrity of the material.

[0039] To further prevent the platform plate 2 from tipping over during loading, several counterweights are slidably arranged in a circular array at the bottom of the support plate 11. The counterweights are evenly distributed to ensure the stability of the platform in all directions. The position of the counterweights can be manually adjusted and fixed according to the material distribution. The counterweights increase the weight at the bottom of the platform, thereby improving the overall stability of the platform. Especially when loading heavy materials, the counterweights can effectively prevent the platform from tipping over due to uneven force.

[0040] In practical use, during loading, the material is poured onto the base plate 4 inside the fixed frame 3. The stability of the platform plate 2 and the deformation of the buffer part 5 are observed. The base plate 4 will slide downward slightly, and the side plate 41 will slide in the slide groove 33 accordingly. The position of the counterweight block is adjusted as needed. During unloading, the cross lifting mechanism is moved to the vicinity of the transport vehicle, the baffle 35 is slid outward from the limiting frame 34, and its position is fixed with screws 36. Then, the cylinder 12 is activated, causing its output shaft to extend and push the second connecting block 22 fixedly connected to it. A connecting block 21 is hinged to a second connecting block 22. One end of the platform plate 2 will gradually rise, causing the whole to tilt. Then, the opening and closing door 31 is opened so that the lower door 312 rests on the transport vehicle compartment. Under the action of gravity, the material will slide down along the bottom plate 4 and the opening and closing door 31 into the compartment. At the same time, the ball bearings 43 on the bottom plate 4 will rotate freely as the material moves, further promoting the smooth unloading of the material. The broken material in the groove 42 is also poured out. After unloading is completed, the opening and closing door 31 is closed and the baffle 35 is reset. The cylinder 12 is started to restore the platform plate 2 to a horizontal state.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
