Description

Technical Field

[0001] The invention belongs to the technical field of mining equipment, and in particular relates to a position fixing device for mining equipment. Background Art

[0002] Mining machinery and equipment refers to machinery that is specialized in mining, mineral processing and prospecting. A large number of cranes, conveyors, ventilators and drainage machinery used in mining operations are collectively referred to as mining machinery and equipment. Among mining machinery and equipment, mining equipment is mainly used for mining minerals. In the process of mining crushing or due to the uneven installation position, it is very easy to cause vibration of mining machinery, resulting in mechanical displacement.

[0003] For example, Chinese invention CN115560219A discloses a mining machinery base with a shock-absorbing function. By setting a shock-absorbing mechanism at the lower end of the connecting bottom plate, the vibration of the mining machinery during mining will be buffered and reduced by the spring, so that the device will not cause position deviation during operation. The ground-gripping drill bit is used to drill into the ground, thereby forming a fastening and fixing effect between the entire device and the ground.

[0004] However, the above-mentioned fixed base of the prior art only has a fixing function. When the ground is uneven, the bottom plate of the base cannot maintain a horizontal position, which directly affects the fixing effect of the mechanical equipment. The overall adaptability and practicality are poor. Summary of the invention

[0005] The purpose of the present invention is to provide a position fixing device for mining equipment, which drives the support platform to rotate horizontally through a turntable, and adjusts the inclination angle of the support platform by moving the support platform along an arc track, so that the support platform can maintain a horizontal state, thereby solving the problem that the existing support platform cannot maintain a horizontal state, affecting the fixing effect of mechanical equipment, and having poor overall adaptability and practicality.

[0006] To solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The present invention is a position fixing device for mining equipment, comprising a fixed base, which is rotatably connected to a turntable; the upper surface of the turntable is connected to a driving mechanism and two arc-shaped tracks, and the two arc-shaped tracks are slidably connected to a support platform. The driving mechanism is transmission-connected to the support platform and is used to drive the support platform to move along the arc-shaped tracks to adjust the inclination angle of the support platform relative to the fixed base, and through the rotation of the turntable, the support platform is rotated in the horizontal direction, so that the support platform can maintain a horizontal state.

[0008] As a preferred technical solution of the present invention, the arc track is a concave structure with high ends and a low middle, and a connecting plate that is fixedly connected to the lower surface of the support platform is connected to the arc track in a one-to-one correspondence.

[0009] As a preferred technical solution of the present invention, the driving mechanism includes a worm, a driving device connected to the worm gear and a fan-shaped worm wheel fixedly connected to the support platform.

[0011] As a preferred technical solution of the present invention, the transmission assembly includes a transmission worm wheel fixedly connected to the worm and a transmission worm meshing with the transmission worm wheel.

[0012] As a preferred technical solution of the present invention, the fan-shaped worm gear is connected to the side of the connecting plate.

[0013] As a preferred technical solution of the present invention, it also includes a plurality of fixed ground nails, and the fixed base is provided with a plurality of through holes for the fixed ground nails to penetrate the through holes and be inserted into the ground to fix the position of the fixed base.

[0014] As a preferred technical solution of the present invention, the fixed base is fixedly connected with a fixed sleeve corresponding to the through hole one by one, and the inner wall of the fixed sleeve is provided with an internal thread; the upper end of the fixed ground nail is fixedly connected with a stud that cooperates with the inner wall thread of the fixed sleeve, and the upper end of the stud is provided with a clamping part, which is used to drive the fixed ground nail to move axially and insert into the ground by rotating the stud.

[0015] As a preferred technical solution of the present invention, the fixed sleeve is arranged obliquely relative to the fixed base, and the through hole is arranged coaxially with the fixed sleeve, so as to allow the fixed ground nail to be inserted into the ground surface obliquely.

[0016] As a preferred technical solution of the present invention, threaded connection holes are evenly distributed on the surface of the support platform.

[0017] The present invention has the following beneficial effects:

[0018] The present invention is connected to the support platform through a driving mechanism, and the support platform is driven to move along the arc track to adjust the inclination angle of the support platform relative to the fixed base. The turntable is rotated to realize the rotation of the support platform in the horizontal direction, so that the fixed base is tilted, and the support platform can be flexibly adjusted to keep it in a horizontal state, thereby ensuring the fixing effect of the mechanical equipment and effectively improving the overall adaptability and practicality.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0035] See also Figure 1 and 2 As shown, the present invention is a position fixing device for mining equipment, comprising a fixed base 1, which is rotatably connected to a turntable 2 via a worm gear rotary drive, and the turntable 2 is driven to perform circular rotation via the worm gear rotary drive.

[0036] like Figure 6 and 7 As shown, the upper surface of the turntable 2 is connected with a driving mechanism and two arc-shaped rails 201 arranged side by side, and the two arc-shaped rails 201 are slidably connected with a support platform 3. The surface of the support platform 3 is evenly provided with threaded connection holes 302, which are convenient for fixing the position of the mining equipment and the support platform 3 by screwing a pressure plate or a right-angle plate.

[0037] The arc track 201 is a concave structure with high ends and a low center. A connecting plate 301 connected to the arc track 201 in a one-to-one correspondence is welded or screwed to the lower surface of the support platform 3 .

[0038] like Figures 5 to 7 As shown, the driving mechanism is connected to the support platform 3 for driving the support platform 3 to move along the arc track 201. Specifically, the driving mechanism includes a worm 202, a driving device 203 connected to the worm 202, and a fan-shaped worm gear 204 fixedly connected to the support platform 3. The fan-shaped worm gear 204 is meshed with the worm 202 and is concentrically arranged with the arc track 201.

[0039] There are two worms 202, and the two worms 202 are connected to the same driving device 203 through a transmission assembly, so that the driving device 203 can drive the two worms 202 to rotate at the same time. The fan-shaped worm wheel 204 can be a curved arc block, and the overall volume and weight of the fan-shaped worm wheel 204 can be flexibly reduced by machining teeth on the arc surface for meshing with the worm 202. The two fan-shaped worm wheels 204 are respectively connected to the sides of the two connecting plates 301 by screws.

[0040] The transmission assembly includes a transmission worm wheel 205 fixedly connected to the rotating shaft of the worm 202 and a transmission worm 206 meshing with the transmission worm wheel 205. The output shaft of the driving device 203 is connected to a T-type transmission box, and the two output shafts of the T-type transmission box are connected to the transmission worm 206, thereby driving the two transmission worms 206 to rotate at the same time.

[0041] like Figures 8 to 10 As shown, the transmission worm 206 drives the transmission worm wheel 205 meshing with it to rotate, so that the two worms 202 rotate synchronously, and then drives the fan-shaped worm wheel 204 to rotate, so as to adjust the inclination angle of the support platform 3 relative to the fixed base 1, and through the rotation of the turntable 2, the support platform 3 is rotated in the horizontal direction, so that the support platform 3 can maintain a horizontal state.

[0042] For example, when the ground in the mining area is uneven, the fixed base 1 is in an inclined state when placed on the ground, so that the support platform 3 is also in an inclined state. At this time, the fan-shaped worm gear 204 is driven by the worm 202 to adjust the inclination state of the support platform 3, and then the turntable 2 is rotated to adjust the circumferential position of the support platform 3, so that the support platform 3 can compensate for the inclination angle caused by the fixed base 1, so that the support platform 3 can be flexibly adjusted to a horizontal state, ensuring the fixing effect of the mechanical equipment, and effectively improving the overall adaptability and practicality.

[0043] As a preferred embodiment, Figures 3 to 5 As shown, a level bubble can be installed on the support platform 3, so as to facilitate observation of the horizontal state of the support platform 3 and improve convenience during adjustment.

[0044] In addition, it also includes four fixed ground nails 4. The fixed base 1 is provided with four through holes. The four through holes are arranged in a circular array along the turntable 2. The fixed ground nails 4 penetrate the through holes and are inserted into the ground to fix the position of the fixed base 1, thereby ensuring the overall fixing effect.

[0045] As another preferred embodiment, Figure 7As shown, the fixed base 1 is welded with a fixed sleeve 401 corresponding to the through hole one by one, and the inner wall of the fixed sleeve 401 is provided with an internal thread. The upper end of the fixed ground nail 4 is fixedly connected with a stud 402 that matches the inner wall thread of the fixed sleeve 401, and the upper end of the stud 402 is provided with a clamping part 403. The fixed ground nail 4, the stud 402, the stud 402 and the clamping part 403 can be an integrated structure. The clamping part 403 is convenient for clamping with a wrench, or a structure that is convenient for matching with a jackhammer. The jackhammer drives the stud 402 to rotate, and the threaded match is used to make the stud 402 move axially, so as to drive the fixed ground nail 4 to move axially and insert into the ground surface, thereby improving the convenience of operation.

[0046] And, if Figure 5 As shown, the fixed sleeve 401 is arranged obliquely relative to the fixed base 1, and the through hole is arranged coaxially with the fixed sleeve 401, so that the fixed ground nail 4 is inserted obliquely into the ground. The fixed ground nail 4 inserted obliquely into the ground can not only improve the position limitation in the horizontal direction, but also increase the position limitation ability in the direction perpendicular to the ground, thereby avoiding the situation where the fixed ground nail 4 is easily pulled out due to the vibration of the equipment in the inclined position of the ground, so that the overall fixing effect is further improved.
