Description

Technical Field

[0001] This invention relates to a highly stable mounting bracket and an ore crushing equipment using the same, which is mainly used in ore crushing and processing. It can effectively improve the construction safety of relevant workers while maintaining normal ore crushing operations. Background Technology

[0002] After mining is completed, the ore needs to be initially crushed by a jaw crusher. The material after initial crushing is then further crushed by cone crushers, multi-cylinder cone crushers and other equipment. After crushing, the material is then ground and sorted.

[0003] To improve the initial crushing efficiency of ore, existing jaw crushers are typically installed in an elevated position using mounting brackets. This raises the discharge port of the jaw crusher to a certain height, allowing for convenient output of the initially crushed material via a conveyor belt located below the discharge port. The feed end of the jaw crusher faces the guide hopper of the mounting bracket to facilitate the entry of ore. Due to the heavy weight of the jaw crusher and the significant vibration during operation, the main support structure of existing mounting brackets generally uses reinforced concrete support columns and equipment installation floors, while the guide hopper is supported by a corresponding steel structure. During equipment operation, operators frequently need to climb to the top of the steel structure of the mounting bracket to observe the ore feed. The significant vibration during jaw crusher operation causes noticeable swaying in the steel structure of the mounting bracket during actual use, resulting in relatively weak structural stability and posing a significant safety hazard.

[0004] Therefore, the research objective of this invention is to design a highly stable mounting bracket that can significantly reduce the amount of vibration transmitted from the operation of a jaw crusher to the steel structure, thereby effectively and significantly improving the structural stability of the steel structure of the mounting bracket and thus effectively reducing safety hazards, as well as the ore crushing equipment using it. Summary of the Invention

[0005] In view of the technical problems existing in the prior art, the present invention provides a high-stability mounting bracket and an ore crushing device using the same, which can effectively solve the technical problems existing in the prior art.

[0006] The technical solution of this invention is: A high-stability mounting bracket, comprising: The equipment installation floor is supported by several corresponding support columns for suspended installation, and a corresponding material discharge port is provided in the middle of the equipment installation floor. The hopper mounting plate is fixedly installed on the upper part of the equipment installation floor by corresponding columns, and a corresponding guide hopper is provided in the middle of the hopper mounting plate facing downward. The column connection mechanism includes a plurality of mounting columns fixedly installed on the equipment installation floor. Each mounting column has a bottom side that abuts against a lower limit plate on the equipment installation floor. The bottom of each column is fixed to the mounting column by a threaded connection. The multi-functional limiting mechanism includes a fixing sleeve fitted on the bottom side of the column, with its bottom end fixed to the equipment mounting floor. The upper inner wall of each fixing sleeve is fixed with a corresponding upper limit plate. The multi-functional limiting mechanism comprises multiple upper and lower fixing teeth arranged in a ring array on the upper and lower limit plates. Opposite sides of the upper and lower fixing teeth are respectively provided with pressing inclined surfaces with opposite directions. Corresponding annular vibration damping boxes are movably installed between the upper and lower fixing teeth. The annular vibration damping boxes are filled with damping material, and the upper and lower ends of the annular vibration damping boxes are respectively provided with slots adapted to the upper and lower fixing teeth. The upper and lower fixing teeth are fixedly embedded in the corresponding slots by corresponding rubber gaskets.

[0007] The equipment installation floor slab and support columns are made of reinforced concrete, and the bottom of the installation columns is pre-embedded in the equipment installation floor slab.

[0008] The bottom side of the fixed sleeve is fixed with a corresponding mounting ring plate, and the mounting ring plate is fixedly installed to the equipment installation floor by the corresponding expansion bolts.

[0009] The bottom side of the column is provided with a number of corresponding anti-deflection threaded holes at equal angles. The fixing sleeve is spaced apart from the column. The annular vibration damping box is provided with relief holes corresponding to the anti-deflection threaded holes. The circumferential position of the annular vibration damping box is limited by the corresponding tightening bolts cooperating with the anti-deflection threaded holes. The rod ends of the tightening bolts are respectively installed into the corresponding anti-deflection threaded holes. The heads of the tightening bolts are respectively movable and abut against the outer side wall of the annular vibration damping box. The diameter of the relief hole is larger than the outer diameter of the rod end of the tightening bolt.

[0010] The heads of the tightening bolts are each rotatably fitted with corresponding abutment balls, which can rotatably abut against the outer side wall of the annular vibration damping box.

[0011] The inner ends of the upper limit plate are integrally formed with corresponding connecting blocks, which are fixed to the side wall of the column by spot welding.

[0012] The damping material is a spherical damping particle made of various metallic or polymeric materials.

[0013] The equipment installation floor and hopper installation plate are respectively fixed with corresponding guardrails, and the equipment installation floor and hopper installation plate are respectively provided with corresponding climbing stairs.

[0014] An ore crushing device includes the aforementioned high-stability mounting bracket and a jaw crusher fixedly mounted on the equipment mounting floor of the high-stability mounting bracket. The feed inlet of the jaw crusher is directly opposite the guide hopper of the hopper mounting plate, and the discharge outlet of the jaw crusher is directly opposite the discharge outlet of the equipment mounting floor.

[0015] The bottom side of the equipment installation floor is provided with a discharge conveyor belt for discharging the material output from the discharge port, and the feed end of the guide hopper is connected to the discharge end of the corresponding guide chute.

[0016] Compared with the prior art, the advantages and positive effects of the present invention are as follows: 1) This invention uses the mounting column of the column connection mechanism to fix and connect the column supporting the hopper mounting plate. Then, fixing sleeves are respectively fitted onto the bottom side of the column, forming an installation space between the lower limit plate of the mounting column and the upper limit plate of the fixing sleeve, facilitating the further addition of a multi-functional limiting mechanism. With the intervention of the multi-functional limiting mechanism, the annular vibration damping box can effectively be positioned in a certain movable state between the upper and lower limit plates. Since the inclined surfaces of the upper and lower fixing teeth are opposite in direction, and rubber pads are respectively placed between the upper and lower fixing teeth and the grooves of the annular vibration damping box, the vibrations transmitted downwards through the upper limit plate and upwards through the lower limit plate can effectively form destructive interference on the annular vibration damping box, resulting in a significant vibration damping effect. Furthermore, the vibrations transmitted downwards through the upper limit plate and upwards through the lower limit plate can also drive the annular vibration damping box to oscillate back and forth between the upper and lower limit plates, effectively creating a significant energy dissipation effect, thereby further significantly improving the vibration damping effect. This ultimately achieves the following: significantly reducing the amount of vibration transmitted from the jaw crusher during operation to the column and hopper mounting plate, thereby effectively and significantly improving the structural stability of the column and hopper mounting plate, and thus effectively reducing the safety hazards for personnel working on the hopper mounting plate.

[0017] 2) The bottom side of the column of this invention is provided with a plurality of corresponding anti-deflection threaded holes at equal angles. The fixing sleeve is spaced apart from the column, and the annular vibration damping box is provided with clearance holes corresponding to the anti-deflection threaded holes. The corresponding tightening bolts cooperate with the anti-deflection threaded holes to limit the circumferential position of the annular vibration damping box. The shank end of the tightening bolt is installed into the corresponding anti-deflection threaded hole, and the head of the tightening bolt is movable against the outer wall of the annular vibration damping box through the abutment ball. The clearance holes provide clearance for the tightening bolts after screwing, and the abutment ball provides axial deflection circumferential limitation for the annular vibration damping box. Thus, without affecting the small-amplitude oscillation of the annular vibration damping box, it effectively prevents excessive displacement of the annular vibration damping box in the oscillating state, which would cause its small-amplitude oscillation to be unable to be maintained, thereby effectively improving the practical effect of this invention.

[0018] 3) The inner end of the upper limit plate of the present invention is integrally formed with corresponding connecting blocks. The connecting blocks are fixed to the side wall of the column by spot welding. This effectively strengthens the fixing effect of the column while reducing the amount of vibration transmitted from the fixed sleeve to the column, thereby effectively ensuring the practical effect of the present invention.

[0019] 4) The ore crushing equipment of the present invention includes a high-stability mounting bracket and a jaw crusher fixedly mounted on the equipment mounting floor of the high-stability mounting bracket. The feed inlet of the jaw crusher faces the guide hopper of the hopper mounting plate, and the discharge outlet of the jaw crusher faces the discharge outlet of the equipment mounting floor. Because the hopper mounting plate support column of the high-stability mounting bracket of the present invention has sufficient vibration damping effect between itself and the equipment mounting floor, the structural stability of the column and the hopper mounting plate can be significantly improved. This significantly improves the safety of personnel performing operations such as observing ore feeding on the hopper mounting plate. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0028] Example 1: refer to Figure 1-6 A high-stability mounting bracket, comprising: The equipment installation floor slab 1 is suspended in the air by several corresponding support columns 2, and a corresponding material discharge port 3 is provided in the middle of the equipment installation floor slab 1; The hopper mounting plate 4 is fixedly installed on the upper part of the equipment installation floor 1 by corresponding columns 5, and a corresponding guide hopper 6 is provided in the middle of the hopper mounting plate 4 facing downward. The column connection mechanism 7 includes a plurality of mounting columns 701 fixedly installed on the equipment installation floor 1. A lower limit plate 702 with its bottom side abutting against the equipment installation floor 1 is fixedly connected to the mounting column 701. The bottom of the column 5 is fixed to the mounting column 701 by threaded connection. The multi-functional limiting mechanism 8 includes a fixing sleeve 9 on the bottom side of the column 5, which is fixed to the bottom end of the equipment installation floor 1. The upper part of the inner side wall of the fixing sleeve 9 is fixed to the corresponding upper limit plate 10. The multi-functional limiting mechanism 8 includes a plurality of upper fixing teeth 801 and lower fixing teeth 802 arranged in a ring array on the upper limit plate 10 and the lower limit plate 702. The upper fixing teeth 801 and the lower fixing teeth 802 are respectively provided with pressing inclined surfaces with opposite inclined directions on opposite sides. The corresponding annular vibration damping box 803 is movably installed between the upper fixing teeth 801 and the lower fixing teeth 802. The annular vibration damping box 803 is filled with vibration damping material 11. The upper and lower ends of the annular vibration damping box 803 are respectively provided with slots that are adapted to the upper fixing teeth 801 and the lower fixing teeth 802. The upper fixing teeth 801 and the lower fixing teeth 802 are respectively fixedly embedded in the corresponding slots by corresponding rubber gaskets 12.

[0029] The present invention uses the mounting column 701 of the column connecting mechanism 7 to fix and connect the support column 5 of the hopper mounting plate 4, and then the fixing sleeve 9 is respectively sleeved on the bottom side of the column 5, and an installation space is formed between the lower limit plate 702 of the mounting column 701 and the upper limit plate 10 of the fixing sleeve 9, so as to facilitate the further addition of the multi-functional limiting mechanism 8. With the intervention of the multi-functional limiting mechanism 8, the annular vibration damping box 803 can be effectively positioned in a certain movable state between the upper limit plate 10 and the lower limit plate 702. Since the inclined surfaces of the upper fixed teeth 801 and the lower fixed teeth 802 are opposite in direction, and rubber pads 12 are respectively placed between the upper fixed teeth 801 and the lower fixed teeth 802 and the slots of the annular vibration damping box 803, the vibrations transmitted downward through the upper limit plate 10 and upward through the lower limit plate 702 can effectively form destructive interference on the annular vibration damping box 803, thereby forming a significant vibration damping effect. Furthermore, the vibrations transmitted downward through the upper limit plate 10 and upward through the lower limit plate 702 can also drive the annular vibration damping box 803 to oscillate back and forth between the upper limit plate 10 and the lower limit plate 702, thereby effectively forming a significant energy dissipation effect and further significantly improving the vibration damping effect. This ultimately achieves the following: significantly reducing the amount of vibration transmitted from the jaw crusher during operation to the column 5 and the hopper mounting plate 4, thereby effectively and significantly improving the structural stability of the column 5 and the hopper mounting plate 4, and thus effectively reducing the safety hazards for relevant personnel when working on the hopper mounting plate 4.

[0030] The equipment installation floor slab 1 and the support column 2 are both made of reinforced concrete. The bottom of the installation column 701 is pre-embedded in the equipment installation floor slab 1. The bottom side of the fixing sleeve 9 is fixedly connected with a corresponding installation ring plate 901, and the installation ring plate 901 is fixedly installed to the equipment installation floor slab 1 by corresponding expansion bolts 13.

[0031] The bottom side of the column 5 is provided with a number of corresponding anti-deflection threaded holes 14 at equal angles. The fixed sleeve 9 is spaced apart from the column 5. The annular vibration damping box 803 is provided with relief holes 15 corresponding to the anti-deflection threaded holes 14. The circumferential position of the annular vibration damping box 803 is limited by the corresponding tightening bolts 16 cooperating with the anti-deflection threaded holes 14. The rod ends of the tightening bolts 16 are respectively installed into the corresponding anti-deflection threaded holes 14. The heads of the tightening bolts 16 are respectively movable and abut against the outer side wall of the annular vibration damping box 803. The diameter of the relief hole 15 is larger than the outer diameter of the rod end of the tightening bolt 16.

[0032] The head of each tightening bolt 16 is rotatably fitted with a corresponding abutting ball 17, which can rotatably abut against the outer side wall of the annular vibration damping box 803.

[0033] By providing clearance holes 15 to allow clearance for the tightening bolts 16 after screwing, and by intervening with the abutting balls 17, the annular damping box 803 is axially deflectable and circumferentially limited. This effectively prevents excessive displacement of the annular damping box 803 in an oscillating state from causing it to lose its small-amplitude oscillation without affecting its small-amplitude oscillation, thereby effectively improving the practical effect of the present invention.

[0034] The inner end of the upper limit plate 10 is integrally formed with corresponding connecting blocks 18, which are fixed to the side wall of the column 5 by spot welding. This effectively strengthens the fixing effect of the column 5 while reducing the amount of vibration transmitted from the fixing sleeve 9 to the column 5, thereby further ensuring the practical effect of the present invention.

[0035] The damping material 11 is a spherical damping particle made of various metal materials or polymer materials. In this embodiment, the damping material 11 is a spherical damping particle made of various metal materials.

[0036] The equipment installation floor slab 1 and the hopper installation plate 4 are respectively fixed with corresponding guardrails 19, and the equipment installation floor slab 1 and the hopper installation plate 4 are respectively provided with corresponding climbing stairs 20.

[0037] Example 2: An ore crushing device includes a high-stability mounting bracket as described in Embodiment 1, and a jaw crusher 21 fixedly mounted on the equipment mounting floor 1 of the high-stability mounting bracket. The feed inlet of the jaw crusher 21 is directly opposite the guide hopper 6 of the hopper mounting plate 4, and the discharge outlet of the jaw crusher 21 is directly opposite the discharge outlet 3 of the equipment mounting floor 1.

[0038] The bottom side of the equipment installation floor slab 1 is provided with a discharge conveyor belt 22 for discharging the material output from the discharge port 3, and the feed end of the guide hopper 6 is connected to the discharge end of the corresponding guide trough 23.

[0039] Because the support column 5 of the hopper mounting plate 4 of the high-stability mounting bracket of the present invention has a sufficient vibration reduction effect between it and the equipment mounting floor 1, the structural stability of the column 5 and the hopper mounting plate 4 can be significantly improved. In this way, the safety of relevant operators when observing ore feeding on the hopper mounting plate 4 can be significantly improved.

[0040] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments that can be applied to other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
