Description

Technical Field

[0001] The invention relates to the technical field of mechanical supports, and in particular to a high-stability mechanical support device for mines. Background Art

[0002] Mining machinery is machinery directly used for operations such as mineral mining and enrichment, including mining machinery and mineral processing machinery. Mechanical support device refers to the outer shell or base used to support, fix or guide moving parts in mechanical equipment, so that the equipment can be more stable during operation and prevent the mechanical equipment from shaking as a whole during operation. At present, when supporting the machinery, support rods and support seats in the support device are required to contact it with the ground to ensure that the support device and the ground remain stable, which is conducive to the machinery being more stable during operation; since the support device cannot be expanded or contracted by adjustment, the support device always maintains the same contact area with the ground during support, and the mine road surface is uneven and prone to more slopes, resulting in the support device being unable to switch accordingly according to the support environment during support, causing the device to tilt or become unstable on uneven ground, making the device unable to adapt to ground with different slopes, affecting the adaptability of the device. Summary of the invention

[0003] The object of the present invention is to provide a high stability mechanical support device for mines to solve the above-mentioned deficiencies in the technology.

[0004] In order to achieve the above object, the present invention provides the following technical solution: a high-stability mechanical support device for mines, comprising: A support base and a moving wheel, wherein the moving wheel is used to drive the support base to move, and a plurality of supporting legs are installed on the support base, and the plurality of supporting legs are distributed at the four corners of the support base; Two groups of support components are used to cooperate with the support legs to play an extension role and keep the support base stable with the slope. The support component includes a support frame installed on the support leg, a vertical rod slidably connected to the bottom of the support frame, and a side leg fixed to the side of the vertical rod away from the support frame. A power component for driving the two groups of support components to move is provided on the support base. The power component includes a stabilizing frame fixed between the support leg and the support base, a sliding sleeve slidably connected inside the support leg for the support frame to be fixedly connected, and a first telescopic motor fixed to the stabilizing frame and the support leg. The sliding sleeve is sleeved on the telescopic end of the first telescopic motor. An extension support leg cooperating with the first telescopic motor is slidably connected inside the support leg. An expansion component is provided on the support leg, and the expansion component is used to drive the vertical rod and the side leg to move along the outside of the support leg, increasing the contact surface between the support leg and the slope. An adaptive component for cooperating with the slope is provided on the side leg, and the adaptive component is used to keep the side leg stable with the slope. And the number of the two groups of support components is equal to the number of the support legs, and the two groups of support components are distributed outside the support legs, so that a triangular structure is formed between the two groups of support components and the support legs. The triangular structure has high stability. At the same time, the stabilizing frame is arranged in a triangular structure, so that the stabilizing frame is located between the two groups of support components, ensuring that the two groups of support components can move along the guides on both sides of the stabilizing frame. And the support component can finely adjust the distance between the support leg and the slope to adapt to different terrain slopes, so that the support leg is finely adjusted according to the change of the terrain, thereby ensuring the stability of the whole support structure. At the same time, the support component can effectively disperse the pressure, reduce the shaking or inclination caused by uneven terrain, and is used to keep the support base stable with the slope, thereby ensuring the stable operation of the machine. And the number of the expansion components is equal to the number of the support components, so that the expansion components and the support components cooperate with each other, and can push the vertical rod and the side leg along one side of the support leg, so that the distance between the vertical rod and the support leg can be freely adjusted. And the top of the extension support leg is fixedly connected to the output end of the first telescopic motor. Then the first telescopic motor pushes the extension support leg to slide out along the inside of the support leg, so that the extension support leg contacts the ground, which is beneficial to play an extension role for the support leg, so that the support leg intermittently contacts the ground, ensuring the stability between the support base and the ground.

[0005] Preferably, the extension component includes a fixing frame fixed outside the support leg, a slider fixed on the top of the vertical rod, and a sliding groove opened on the top of the support frame for the slider to slide.

And the adapter arm is movably sleeved on the adapter shaft column, so that the adapter arm is movably connected between the fixing frame and the vertical rod. Then, when the vertical rod moves downward, the adapter arm on its outside moves downward. Then, the inside of the adapter arm moves around the outer circumference of the adapter shaft column and pushes the vertical rod to move, so that the distance between the vertical rod and the side leg and the support leg is finely adjusted. This enables the support leg to quickly respond to the slope, ensuring that the moving wheels fit the slope more stably and improving the adaptability of the moving wheels. In addition, the coordinated adjustment of the extension component and the support component reduces the time required for device adjustment, thus improving the overall installation efficiency.

In addition, the two stable seats are slidingly connected to the side legs, so that the gear is meshed with the two racks and moves downward synchronously in the positioning groove, which can increase the adaptability between the side legs and the slope surface. The adaptive height difference adjustment allows the side legs to automatically adjust to the slope surface, which can ensure that the side legs are closely fitted to the slope surface, reduce the problem of unstable support or tilt caused by excessive height difference, thereby significantly improving the overall stability of the support device and improving the applicability of the equipment.

[0008] Preferably, a guide block is fixed on the side of the stabilizing seat away from the rack, and a guide groove for the guide block to slide is opened in the positioning groove: this is conducive to maintaining stable guiding movement between the stabilizing seat and the positioning groove, and improving the stability of the movement of the stabilizing seat.

[0022] The extension component 3 includes a fixing frame 31 fixed to the outside of the supporting leg 12, a slider 35 fixed to the top of the vertical rod 26, and a slide groove 34 opened at the top of the supporting frame 25 for the slider 35 to slide.

A receiving component 5 is provided in the slide groove 34, and the receiving component 5 is used to drive the adaptive component 4 to move.

[0023] During use: first, the moving wheel 11 contacts the ground and drives the support base 1 to move, then the support base 1 moves to the installation position, and the first telescopic motor 24 moves to push the extended leg 22 to slide out along the support leg 12, so that the extended leg 22 can contact the ground in advance, and then the telescopic end of the first telescopic motor 24 moves synchronously to drive the sliding sleeve 23 to move synchronously along the support leg 12, at this time, the sliding sleeve 23 moves to drive the support frame 25 and the vertical pole 26 to move downward, so that the side leg 27 slowly contacts the slope, and the vertical pole 26 drives the connecting arm 33 on its outside to move downward, and the inside of the connecting arm 33 moves around the outer circumference of the connecting shaft column 32 and drives the vertical pole 26 to move, so that the distance between the vertical pole 26 and the side leg 27 and the support leg 12 is fine-tuned, so that the receiving component 5 drives the adaptive component 4 moves downward to contact the slope, so that the side leg 27 forms indirect contact with the slope under the action of the adaptive component 4, so that the side leg 27 is extended along the outside of the support leg 12 and the stabilizing frame 21, and a triangular structure is formed between the extended support leg 22, the upright 26, the side leg 27 and the support leg 12, which can effectively disperse the pressure and reduce the shaking or tilting caused by uneven terrain, which is beneficial for the support leg 12 to have a larger contact surface with the ground, and then the extended support leg 22 and the side leg 27 are in contact with the slope, which is used to fine-tune the distance between the support leg 12 and the slope to adapt to different terrain slopes, so that the support leg 12 is fine-tuned according to the change of the terrain, thereby ensuring the stability of the entire support structure, and at the same time, it is used to keep the support base 1 stable on the slope, thereby ensuring the stable operation of the machine and improving the adaptability of the device.

[0024] refer to Figures 1 - 10 As shown, the receiving assembly 5 includes a receiving groove 51 opened on one side of the support frame 25 and communicating with the inside of the slide groove 34, and a receiving block 54 slidably connected to one side of the support frame 25, a second telescopic motor 52 is fixed in the receiving groove 51, a push block 53 is fixed to the telescopic end of the second telescopic motor 52, one side of the push block 53 is fixedly connected to the receiving block 54, a connecting plate 55 is fixed to the bottom of the receiving block 54, and a first moving block 56 is fixed to the bottom end of the connecting plate 55.

[0025] The self-adaptive component 4 includes a positioning groove 41 opened on the side of the side leg 27 away from the vertical rod 26, two stable seats 42 symmetrically slidably connected to the side leg 27, and a push rod 45 installed in the positioning groove 41 and matched with the first moving block 56, and the two stable seats 42 are located in the positioning groove 41, and racks 44 are fixed on the opposite sides of the two stable seats 42, and a gear 46 matching with the two racks 44 is installed on the bottom end of the push rod 45. The two stable seats 42 are fixed on the side close to the two racks 44. A resistance seat 43 is fixed on the side of the two stable seats 42 close to the two racks 44. A protective component 7 is provided on the side leg 27 to match it with the two racks 44, and a reciprocating component 6 is provided on the push rod 45 to match it with the first moving block 56.

[0026] A guide block 47 is fixed to one side of the stabilizing seat 42 away from the rack 44 , and a guide groove 48 for the guide block 47 to slide is defined in the positioning groove 41 .

[0027] The reciprocating assembly 6 includes a second moving block 65 fixed on one side of the push rod 45 and cooperating with the first moving block 56, and a centering block 61 installed on the side of the side leg 27 close to the push rod 45. A spring seat 63 is fixed on the side opposite to the centering block 61 and the second moving block 65, and a spring member 62 is installed between the two spring seats 63; a guide rod 64 is fixed on the side of the centering block 61 close to the spring seat 63, and a moving groove 66 for inserting the guide rod 64 is opened on one side of the second moving block 65.

[0028] Through the above technical solution: When the side legs 27 are in contact with the ground, the adaptive component 4 has two usage modes: The first type: First, when the side leg 27 moves to drive the adaptive component 4 to fit with the ground without a slope, the second telescopic motor 52 extends and retracts to push the push block 53 to slide leftward along the receiving groove 51. Immediately, the push block 53 moves to push the receiving block 54 to move upward along the support frame 25, so that the receiving block 54 moves to drive the connecting plate 55 and the first moving block 56 to move synchronously. At this time, the slope of the first moving block 56 matches the slope of the second moving block 65, so that the first moving block 56 moves upward along the second moving block 65 and pushes the second moving block 65 downward. As the second moving block 65 moves downward, it drives the push rod 45 to move downward along the positioning groove 41. Due to the downward movement of the second moving block 65, the spring seat 63 and the spring member 62 are squeezed on the centering block 61. Subsequently, the push rod 45 moves downward along the positioning groove 41 to drive the gear 46 to move downward along the positioning groove 41. In addition, the gear 46 meshes with the two racks 44 to drive the two racks 44 to move downward along the positioning groove 41 together. Then, the two racks 44 move to drive the two stabilizing seats 42 to move downward along the inside of the positioning groove 41 and the outside of the side leg 27. Through the movement of the two stabilizing seats 42, the guide block 47 is driven to move synchronously along the guide groove 48. Thus, the two stabilizing seats 42 move to push the two abutting seats 43 to contact the ground, so that the side leg 27 and the ground form an indirect contact under the overall cooperation of the adaptive component 4, which is used to keep the side leg 27 in contact with the ground and ensure the stability between the support seat 1 and the ground.

[0029] Second type: First, when the side leg 27 moves to drive the adaptive component 4 to be in contact with the ground and there is a slope, the second telescopic motor 52 expands and contracts to push the push block 53 to slide leftward along the receiving groove 51. Immediately, the push block 53 moves to push the receiving block 54 to move upward along the support frame 25, so that the receiving block 54 moves to drive the connecting plate 55 and the first moving block 56 to move synchronously. At this time, the slope of the first moving block 56 matches that of the second moving block 65, so that the first moving block 56 moves upward along the second moving block 65 and pushes the second moving block 65 downward. As the second moving block 65 moves downward, it drives the push rod 45 to move downward along the positioning groove 41. Due to the downward movement of the second moving block 65, the spring seat 63 and the spring member 62 are squeezed on the centering block 61. Subsequently, the downward movement of the push rod 45 along the positioning groove 41 drives the gear 46 to move downward along the positioning groove 41. In addition, the gear 46 meshes with the two rack bars 44 to drive the two rack bars 44 to move downward together along the positioning groove 41. Then, the movement of the two rack bars 44 drives the two stabilizing seats 42 to move downward along the inside of the positioning groove 41 and the outside of the side leg 27. At the same time, the two stabilizing seats 42 slide along the inside of the positioning groove 41 and the outside of the side leg 27 to drive the two abutting seats 43 to move downward. Furthermore, when the two stabilizing seats 42 and the two abutting seats 43 move downward to contact the ground, due to the height difference between the ground and the side leg 27, one of the stabilizing seats 42 and one of the abutting seats 43 first contact the ground. At this time, the one stabilizing seat 42 and the one abutting seat 43 that contact the ground cannot move downward, and the continuous downward force applied by the push rod 45 will cause the gear 46 to roll along the teeth of one of the rack bars 44 on the fixed stabilizing seat 42. Then, under the meshing of the gear 46 and one of the rack bars 44, the rotating gear 46 will mesh with the other rack bar 44 to drive the other rack bar 44 to continue to move downward along the positioning groove 41. Thus, the other rack bar 44 drives the other stabilizing seat 42 and the other abutting seat 43 to move downward. Subsequently, the other stabilizing seat 42 and the other abutting seat 43 contact the ground, so that the two stabilizing seats 42 and the two abutting seats 43 form a height difference after contacting the slope, which is beneficial to increasing the adaptability between the side leg 27 and the slope surface, enabling the side leg 27 to automatically adjust with the slope surface, ensuring that the side leg 27 can be closely attached to the slope surface, reducing the problems of unstable support or inclination caused by excessive height difference, thereby significantly improving the overall stability of the support device and enhancing the applicability of the equipment.

[0030] Further, the protection component 7 includes a protection plate 72 slidably connected to the side of the positioning groove 41 close to the rack 44, a clamping block 73 fixedly connected to one side of the protection plate 72, and a plug-in block 74 fixedly connected to one side of the clamping block 73. The clamping block 73 and the plug-in block 74 are clamped in the positioning groove 41 and the guiding groove 48. A protective shell 71 is sleeved outside the side leg 27, and the protective shell 71 is fixedly connected to the clamping block 73. Based on this, the protection plate 72 can block the opening of the positioning groove 41, control the exposed surfaces of the rack 44 and the gear 46, and prevent the risk of accidental contact and injury to operators or other personnel. In addition, through physical isolation, the direct damage of external object fragments or tools to the rack 44 and the gear 46 can be reduced, improving the safety of the equipment.
