[0001] This utility model relates to the field of explosion-proof mining bottom lifting machine technology, and in particular to an explosion-proof mining bottom lifting machine based on a three-section boom. Background Technology

[0002] The mine explosion-proof bottom-lifting machine is an engineering machinery equipment specially designed for flammable and explosive environments such as underground coal mines. It is mainly used to excavate and clean the bottom materials (such as rocks, coal slag, etc.) in the mine to maintain the stability of the roadway and improve mining efficiency. The equipment combines explosion-proof technology and engineering machinery functions to ensure safe operation in environments with the risk of gas or coal dust explosions.

[0003] The existing explosion-proof mining bottom lifting machine does not have an effective obstacle removal device during use, and cannot clear obstacles in the movement path during use. As a result, the machine may be unable to move normally due to residual obstacles, which will affect its normal use. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a mining explosion-proof bottom lifting machine based on a three-section arm.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A mining explosion-proof bottom-lifting machine based on a three-section boom includes a clearing assembly. The clearing assembly includes a base, a connecting frame mounted on one side of the base, a hydraulic cylinder mounted on the bottom of the connecting frame, a mounting seat mounted on the bottom of the hydraulic cylinder, an adjusting motor mounted on the outer wall of one side of the mounting seat, an output end of the adjusting motor connected to a mounting shaft, one end of the mounting shaft rotatably passing through the mounting seat, an adjusting frame mounted on the mounting shaft, several sets of springs mounted on one side of the adjusting frame, a bucket mounted on one end of each spring, several sets of guide holes opened on the adjusting frame, guide rods slidably mounted through the guide holes, one end of each guide rod fixed to the bucket, the diameter of the tail end of the guide rod being larger than the diameter of the guide hole, a moving component for moving the position and a digging component for clearing the bottom material are provided on one side of the base.

[0007] As a further embodiment of this utility model: the moving component includes a drive motor, which is installed at the bottom of the base. A transmission shaft is connected to one side of the drive motor, and a moving wheel is installed on the transmission shaft. Several sets of anti-slip patterns are provided around the moving wheel.

[0008] As a further embodiment of this utility model: the excavation assembly includes a multi-axis three-section boom, which is mounted on the top of the base, and a bucket is provided at the end of the multi-axis three-section boom.

[0009] As a further improvement of this utility model: an explosion-proof electrical cabinet is installed on the top of the base, and a hinge is provided on one side of the explosion-proof electrical cabinet. A cabinet door is installed through the hinge, and the size of the cabinet door is adapted to the explosion-proof electrical cabinet. The explosion-proof electrical cabinet is made of aluminum alloy.

[0010] As a further improvement of this utility model: a fixing plate is installed on one side of the explosion-proof electrical cabinet, and a fixing shaft is installed on one side of the fixing plate. A limit block is installed by rotating the fixing shaft, and the size and position of the limit block are adapted to the cabinet door.

[0011] As a further embodiment of this utility model: a water storage tank is installed on the top of the base, a delivery pump is connected to one side of the water storage tank, a spray frame is connected to the output end of the delivery pump, a water inlet is connected to the top of the water storage tank, and a sealing plug is provided at one end of the water inlet.

[0012] As a further improvement of this utility model: a transparent viewing window is provided on one side of the cabinet door, and the viewing window is made of tempered glass.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The height and angle of the bucket can be adjusted through the obstacle clearing component. When adjusted to a suitable angle, the bucket can be used in conjunction with the movement of the device to efficiently clear obstacles such as gravel in the movement path. This avoids obstacles affecting the normal movement of the device and ensures its normal use. When clearing obstacles, the spring can act as a buffer to prevent damage to the bucket. When the bucket moves and is buffered by the deformation of the spring, the guide rod slides in the guide hole of the adjustment frame to limit the movement trajectory and prevent the bucket from deviating.

[0015] 2. Using aluminum alloy to make explosion-proof electrical cabinets can give them good explosion-proof performance, avoiding personnel injury in the event of an accident. At the same time, aluminum alloy is lightweight, which can avoid affecting the mobility of the equipment.

[0016] 3. The transparent viewing window allows for observation of the interior of the explosion-proof electrical cabinet, facilitating maintenance by staff without opening the cabinet door. This allows for quick inspection of any abnormalities, and the absence of the cabinet door prevents the entry of foreign objects and dust, reducing the risk of malfunctions.

[0022] The technical solution of this utility model will be further described in detail below with reference to specific embodiments.

[0023] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0024] Example 1

[0025] Explosion-proof mining bottom lifting machine based on a three-section boom, such as Figure 1-4 As shown, the system includes a clearing assembly, which includes a base 1. A connecting frame 11 is mounted on one side of the base 1. A hydraulic cylinder 12 is mounted on the bottom of the connecting frame 11. A mounting base 14 is mounted on the bottom end of the hydraulic cylinder 12. An adjusting motor 15 is mounted on the outer wall of one side of the mounting base 14. An installation shaft 24 is connected to the output end of one side of the adjusting motor 15. One end of the installation shaft 24 is rotatably mounted through the mounting base 14. An adjusting frame 16 is mounted on the installation shaft 24. Several sets of springs 25 are mounted on one side of the adjusting frame 16. A bucket 13 is mounted on one end of each spring 25. Several sets of guide holes are provided on the adjusting frame 16. A guide rod 21 is slidably mounted through the guide holes. One end of the guide rod 21 is fixed to the bucket 13. The diameter of the tail end of the guide rod 21 is larger than the diameter of the guide hole. A moving component for moving the position and a digging component for clearing the bottom material are provided on one side of the base 1.

[0026] In use, the moving component allows the device to move within the mine roadway. Once at the designated location, the digging component excavates and cleans materials such as rocks and coal slag from the mine floor. During movement, the motor 15 starts, controlling the rotation of the mounting shaft 24 and the adjusting frame 16, thereby adjusting the bucket 13 to a suitable angle. The hydraulic cylinder 12 adjusts the height of the bucket 13, allowing the angle adjustment to be controlled according to ground conditions. Once the bucket 13 contacts the ground, the movement of the device ensures that the bucket 13 contacts the ground and removes obstacles along the movement path. Efficiently clearing objects such as gravel can avoid affecting the normal movement of the device and ensure its normal use. When clearing obstacles, the spring 25 can act as a buffer. When encountering harder obstacles, the deformation of the spring 25 can act as a buffer when the bucket 13 comes into contact with it, which can reduce the impact force and prevent damage to the bucket 13. When the bucket 13 moves and is buffered by the deformation of the spring 25, the guide rod 21 slides in the guide hole of the adjusting frame 16 to limit the movement trajectory and prevent the bucket 13 from deviating.

[0027] The moving component includes a drive motor 2, which is mounted on the bottom of the base 1. A transmission shaft 3 is connected to one side of the drive motor 2, and a moving wheel 4 is mounted on the transmission shaft 3. Several sets of anti-slip patterns are provided around the moving wheel 4.

[0028] In use, the drive motor 2 can drive the transmission shaft 3 and the moving wheel 4 to rotate. The rotating of the moving wheel 4 in contact with the ground can drive the device to move easily and quickly in the mine roadway, making it convenient to switch positions for operation as needed.

[0029] The excavation assembly includes a multi-axis three-section boom 9, which is mounted on the top of the base 1, and a bucket 10 is provided at the end of the multi-axis three-section boom 9.

[0030] In use, the position and angle of the bucket 10 can be adjusted by the multi-axis three-section boom 9, which can control the movement of the bucket 10 to carry out digging operations. This facilitates the excavation and cleaning of materials at the bottom of the mine, thereby maintaining the stability of the roadway and improving mining efficiency. Both the multi-axis three-section boom 9 and the bucket 10 are mature existing technologies, and any model available on the market can be used. No creative work has been put into them, and those skilled in the art can undoubtedly determine their specific structures. Therefore, they have not been described in detail.

[0031] For explosion protection, such as Figure 1 , 2 As shown, an explosion-proof electrical cabinet 8 is installed on the top of the base 1. A hinge is provided on one side of the explosion-proof electrical cabinet 8, and a cabinet door 18 is installed through the hinge. The size of the cabinet door 18 is adapted to the explosion-proof electrical cabinet 8. The explosion-proof electrical cabinet 8 is made of aluminum alloy.

[0032] When in use, the cabinet door 18 can be opened, and electrical equipment, power supplies and components can be installed through the space inside the explosion-proof electrical cabinet 8. The explosion-proof electrical cabinet 8 is made of aluminum alloy, which gives it good explosion-proof performance and avoids injury to personnel in case of accidents. At the same time, the weight of aluminum alloy is light, which can avoid affecting the mobility of the device.

[0033] To prevent cabinet door 18 from being opened accidentally, such as Figure 2 , 3 As shown, a fixing plate 23 is installed on one side of the explosion-proof electrical cabinet 8, and a fixing shaft 22 is installed on one side of the fixing plate 23. A limit block 20 is installed by rotating the fixing shaft 22. The size and position of the limit block 20 are adapted to the cabinet door 18.

[0034] When in use, after the cabinet door 18 is closed, the limit block 20 can be rotated. The limit block 20 can lock the cabinet door 18 to limit and fix it, thereby preventing the cabinet door 18 from being accidentally opened due to the impact of bumps during movement. There is a certain damping between the limit block 20 and the fixed shaft 22, thereby preventing the limit block 20 from being rotated unnecessarily due to the impact of bumps.

[0035] In order to reduce dust, such as Figure 2 As shown, a water storage tank 6 is installed on the top of the base 1, a delivery pump 17 is connected to one side of the water storage tank 6, a spray frame 5 is connected to the output end of the delivery pump 17, a water inlet 7 is connected to the top of the water storage tank 6, and a sealing plug is provided at one end of the water inlet 7.

[0036] During use, water can be added to the water storage tank 6 through the water inlet 7. After adding water, the sealing plug is closed to prevent dust and other impurities from entering. The water in the water storage tank 6 can be transported by starting the delivery pump 17. The water is delivered to the spray frame 5 and sprayed out in the form of water mist to suppress dust during operation. The water mist spray can effectively prevent the generation of dust and protect the health of the workers.

[0037] Example 2

[0038] For ease of inspection, please refer to Figure 2 Based on the three-section boom mining explosion-proof bottom lifting machine, this embodiment makes the following improvements compared to embodiment 1: a transparent viewing window 19 is provided on one side of the cabinet door 18, and the material of the viewing window 19 is tempered glass;

[0039] During use, the transparent viewing window 19 allows observation of the contents of the explosion-proof electrical cabinet 8, facilitating maintenance by staff without opening the cabinet door 18. This allows for quick inspection of any abnormalities, and the absence of the cabinet door 18 prevents the entry of foreign objects and dust, reducing the risk of malfunctions.

[0040] The above description is only a preferred embodiment of the present utility model. For parts that do not require creative effort in circuit control, signal control and transmission, please refer to the prior art. However, the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope of the technology disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
