Description

Technical Field

[0001] The utility model relates to a test bench for a super-large single-cylinder cone crusher mainframe, belonging to the technical field of single-cylinder cone crusher mainframes. Background Technique

[0002] With the increasing exploitation of domestic low-grade mines, the large-scale development of sand and gravel aggregate projects, and the policy demand for the comprehensive utilization of waste metal slag, the demand for high-performance and highly reliable large crushing equipment is continuously increasing. Super-large single-cylinder cone crushers (with a maximum processing capacity exceeding 1800 t / h) are widely used in medium and fine crushing operations in medium and large mines and sand and gravel aggregate production lines with an annual output of tens of millions of tons due to their advantages such as large crushing ratio, good laminating effect, and large throughput. However, due to many factors such as the complex structure and large weight of key castings and forgings, high requirements for processing dimensional accuracy, complex hot-fitting assembly process, and high requirements for the height and load-bearing of the whole machine assembly and test workshop, only a very small number of domestic manufacturers have the production capacity.

[0003] Before the single-cylinder cone crusher mainframe is shipped out of the factory, it is necessary to verify in advance the reliability of the lubrication system, hydraulic system, sealing device, and operating system to reduce the early failure rate of equipment operation. As a necessary supporting component for the debugging and inspection of the mainframe, traditional small and medium-sized cone crushers mainly use small test benches composed of channel steel and rectangular pipes, with low structural load-bearing capacity (only a few tons). For the debugging operation of super-large single-cylinder cone crusher mainframes, peer manufacturers mainly use temporarily assembled single rigid support seats for "street vending operations", and the load-bearing capacity, generalization, modularization, and use safety of the test bench are poor, and cannot meet the debugging requirements of 100-ton single-cylinder cone crusher mainframes.

[0004] In addition, the testing of super-large tonnage single-cylinder cone crusher mainframes has the following special requirements: First, the load-bearing of the mainframe test bench is ≥100 tons, and the designed steel support structure should ensure its sufficient firmness. The installation height of the mainframe should meet the oil return requirements of the hydraulic lubrication station. The flatness deviation of the ground installation plane is ≤1 mm. When the crusher starts and stops, its horizontal shaking is about 30 mm. The test bench should be equipped with necessary shock-absorbing structures to avoid structural resonance; at the same time, the structural design should ensure no interference with hydraulic and electrical pipelines; Second, the ground foundation load-bearing capacity of the test site should be sufficient to avoid ground crushing; Third, the rated power of the workshop power supply should meet the no-load operation requirements of the mainframe drive motor; Fourth, the load-bearing and workshop height of the lifting equipment should meet the requirements of the maximum component of more than 50 tons and the overall installation height of 9 m; Fifth, power components need to be additionally equipped with three-phase AC motors, pulley sets and taper sleeves, motor pulley sets and taper sleeves, narrow V-belts, distribution cabinets and other equipment facilities, and the belt drive is used instead of the whole machine coupling drive to play a safety protection role. Summary of the Invention

[0005] To solve the problems of insufficient load-bearing capacity of existing small test benches, lack of generalization and modularization of improvised tooling, and poor use safety, based on the requirements of high load-bearing capacity, high precision, high safety, modularization, generalization, and low cost of the mainframe test structure, it is now necessary to design a test bench suitable for a single-cylinder cone crusher mainframe of hundreds of tons to meet the requirements of efficient and high-quality test and inspection operations for the crusher mainframe.

[0054] It should be noted that these drawings and text descriptions are not intended to limit the scope of the concept of the present utility model in any way, but to illustrate the concept of the present utility model to those skilled in the art by referring to specific embodiments. Detailed implementation manners

[0055] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the drawings in the embodiments of the present utility model. The following embodiments are used to illustrate the present utility model but are not used to limit the scope of the present utility model.

[0056] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of the present utility model.

[0057] In the description of the present utility model, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0058] Such as Figure 1 、 Figure 2As shown in the figure, a test bench 10 for an extra-large single-cylinder cone crusher mainframe includes an upper frame 101, an intermediate frame 103, lower support legs 104 and a support assembly; the upper frame 101 is used to assemble the single-cylinder cone crusher mainframe 20 and the drive motor 30, and the output shaft of the drive motor 30 is connected to the input shaft of the single-cylinder cone crusher mainframe 20 through a belt 40; the intermediate frame 103 is assembled directly below the upper frame 101, and there are multiple shock absorbers 102 between the two; the lower support legs 104 are assembled directly below the intermediate frame 103 for raising the overall height of the mainframe test platform; the support assembly is assembled between two adjacent support legs 104 and between the support legs 104 and the intermediate frame 103 for enhancing the support strength of the multiple support legs 104; the support assembly includes an inclined support 105, a horizontal support 106 and a vertical support 107.

[0059] It should be noted that the shock absorbers 102 are rubber shock absorbers, and the upper frame 101 and the intermediate frame 103 are connected through 6 rubber shock absorbers and several bolts and washers; the rubber shock absorbers are divided into 2 specifications, namely four rubber shock absorbers one located below the single-cylinder cone crusher mainframe 20 and two rubber shock absorbers two near the drive motor 30; through the reasonable distribution of the positions of the rubber shock absorbers and the reasonable selection of the elastic modulus, structural resonance is avoided, and the requirement for bearing the lateral shear force during the test operation is met. At the same time, it is ensured that after the single-cylinder cone crusher mainframe 20 and the drive motor 30 are respectively installed, the downward pressure of the upper frame 101 on the rubber shock absorbers is basically the same, so that the installation flatness of the single-cylinder cone crusher mainframe 20 and the drive motor 30 is controlled within a reasonable tolerance range. 4 mounting holes on the upper frame 101 are used to connect to the single-cylinder cone crusher mainframe 20, and are flush with the upper mounting plate of the upper frame 101, and are firmly connected by bolts and nuts (the remaining redundant clearance holes are used to expand the mounting positions to be compatible with the sizes of other specifications of crushers).

[0060] As Figure 1 、 Figure 2 shown in the figure, the intermediate frame 103 is located directly below the upper frame 101, serving as a rigid connection body for intermediate transition, and is directly connected to 6 support legs 104 and 10 inclined supports 105, ensuring the stability and reliability of the overall structure of the test bench.

[0061] As Figure 1 、 Figure 2 shown in the figure, the support legs 104 are located below the intermediate frame 103 and are connected by bolt assembly methods, used to raise the overall height of the test bench to meet the height requirement for viscous lubricating oil to return by gravity, and provide a mounting carrier for the inclined support 105 and the horizontal support 106, and are interconnected to form the entire rigid connection body, supporting the entire rigid frame and avoiding overall structural resonance.

[0062] As Figure 1 、Figure 2 As shown, the diagonal brace 105 is located in the inner space formed by the support leg 104 and the middle frame 103, and is used for the transition connection between the two to assist in supporting the middle frame 103.

[0063] As Figure 1 、 Figure 2 shown, the horizontal brace 106 is located between two adjacent support legs 104 in the horizontal direction, and is used to assist in connecting the adjacent support legs 104, avoid the lateral displacement of the support legs 104 caused by large vibration loads, enhance the overall structural stability, and avoid the vibration and failure caused by structural resonance.

[0064] As Figure 1 、 Figure 2 shown, the longitudinal brace 107 is located between two longitudinal support legs 104 below the middle of the middle frame 103, and realizes the longitudinal position connection of the two support legs 104 through bolt connection, strengthening the structural strength.

[0065] The upper frame described above is further described below.

[0066] As Figure 3 、 Figure 4 、 Figure 5 shown, the upper frame 101 includes a square frame, a cantilever beam 203, a cantilever beam 204, and four opposed mounting seats 205; the square frame is formed by welding two parallel cross beams 201 and two parallel longitudinal beams 202, and the cantilever beam 203 and the cantilever beam 204 are oppositely mounted in the inner frame of the square frame; two of the mounting seats 205 are respectively mounted at the two inner corners of the square frame, and the other two mounting seats 205 are respectively mounted at the angles between the cantilever beam 203, the cantilever beam 204 and the square frame, and the single-cylinder cone crusher main machine 20 is connected to the four mounting seats 205 through four fixing devices 50.

[0067] A further solution: As Figure 3 、 Figure 4 、 Figure 5 shown, both the cross beam 201 and the longitudinal beam 202 are composed of H-shaped steel and a plurality of spaced profile steel plates 206 welded in the H-shaped steel; the heights of the two ends of the longitudinal beam 202 are slightly lower than the height of the cross beam 201, so that the two ends of the longitudinal beam 202 can be inserted into the corresponding cross beam 201 and then welded together.

[0068] It should be noted that the selected section steel is European standard HEB400. Compared with the national standard section steel, the larger thickness of the wing plate significantly enhances the structural stability and meets the high load-bearing requirements; the profile steel plates 206 are distributed discontinuously to enhance the structural rigidity; the cantilever beam 203 and the cantilever beam 204 are strengthened by the diagonal brace 107 to increase the design stability of the cantilever beam structure; the cantilever beam is cut with a slope or a right angle to avoid interference with the single-cylinder cone crusher main machine 20.

[0069] Further solution: As Figure 3 , Figure 4 , Figure 5 shown, the mounting base 205 is a triangular box structure, which is welded by an upper sealing plate, a lower sealing plate and box-shaped rib plates located between the two. At least one mounting hole for assembling the fixing device 50 is provided on the upper sealing plate. The fixing device 50 adapts to the single-cylinder cone crusher mainframe 20 of different sizes by matching mounting holes at different positions; the upper sealing plate at the two inner included angles of the square frame is embedded in the notch opened on the longitudinal beam 202 to increase the contact area with the fixing device 50; the upper sealing plate at the included angles of the first cantilever beam 203, the second cantilever beam 204 and the square frame is embedded in the notch opened on the corresponding cantilever beam to increase the contact area with the fixing device 50.

[0070] It should be noted that the box-shaped rib plates are composed of two closed triangular structures, which enhance the stability of the installation structure of the single-cylinder cone crusher mainframe 20. The adoption of the triangular box structure can meet the installation space size requirements of the single-cylinder cone crusher mainframe 20 and the weight reduction requirement for the hundred-ton load-bearing requirement.

[0071] Further solution: As Figure 3 , Figure 4 , Figure 5 shown, symmetrically arranged motor crossbeam mounting plates 210 are welded on the top surfaces of the two crossbeams 201 of the square frame. Long circular holes for horizontally adjusting the driving motor 30 are provided on the motor crossbeam mounting plates 210; shock absorber mounting threaded plates are welded at the four included angles of the bottom surface of the square frame and at the joints with the first cantilever beam 203 and the second cantilever beam 204 respectively.

[0072] It should be noted that, as Figure 3 , Figure 4 , Figure 5 shown, four shock absorber mounting threaded plates I 208 and two shock absorber mounting threaded plates II 209 are welded on the bottom surface of the square frame respectively. The mounting surfaces, mounting holes of the four upper sealing plates on the top surface of the square frame, and the mounting surfaces and long circular holes of the motor mounting plates are all machined integrally after welding to meet the flatness of the mainframe installation plane, the dimensional accuracy of the associated holes, the flatness of the motor crossbeam mounting plate, and the dimensional accuracy of the associated holes. The mounting surfaces and threaded holes of the six shock absorber mounting threaded plates on the bottom surface of the square frame are also machined integrally after welding to meet the flatness of the shock absorber and the upper and lower frame installation planes and the dimensional accuracy of the associated threaded holes.

[0073] The above-mentioned intermediate frame will be further described below.

[0074] As Figure 6 , Figure 7As shown in the figure, the middle frame includes a square frame formed by welding two parallel H-shaped steel crossbeams 201 and two parallel H-shaped steel longitudinal beams 302; at each of the four corners on the top surface of the square frame and in the middle of the two crossbeams, a shock absorber mounting threaded plate is welded; at each of the four corners on the bottom surface of the square frame and in the middle of the two crossbeams, a support leg mounting seat 305 is welded, and an inclined support mounting plate 306 is welded at the remaining part of the bottom surface of the square frame.

[0075] Further solution: As Figure 6 , Figure 7 shown in the figure, the stiffening plates 307 are discontinuously distributed on the inner and outer sides of the H-shaped steel crossbeam 301 and the H-shaped steel longitudinal beam 302, and double-layer stiffening plates 307 are arranged at the support leg mounting seat 305 placed near the single-cylinder cone crusher mainframe 20 in the area with larger load. The middle frame 103 serves as a rigid intermediate transition body in the middle of the bench. The upper end surface is connected to the upper frame 101 through 4 welded mainframe shock absorber mounting threaded plates 303, 2 welded motor shock absorber mounting threaded plates 304 and shock absorbers of corresponding models, and bears the load of the upper frame 101 and even the whole machine; the lower end surface is connected to 6 support legs 104, which are used to share the load of the bench and the whole machine, and the rest are connected to the inclined support 105 located between the support leg 104 and the middle frame 103, which is used to assist in connecting the middle frame 103 and the support leg 104, and plays a role in strengthening the overall structural stability. The mainframe shock absorber mounting threaded plate 303, the motor shock absorber mounting threaded plate 304, and the support leg mounting seat 305 all adopt the overall machining method after welding to ensure the flatness and the associated dimensions of the threaded holes.

[0076] The following further explains the above-mentioned support legs.

[0077] As Figure 8 shown in the figure, the support leg 104 includes a vertically placed H-shaped steel 401, a top plate 402, a bottom plate 403, and an inclined support mounting plate 404 for connecting with the inclined support; the top plate 402 is welded on the top surface of the H-shaped steel 401 and is used to connect with the middle frame 103; the bottom plate 403 is welded on the bottom surface of the H-shaped steel 401 and is used to connect with the ground foundation; the inclined support mounting plate 404 is located in the middle of the H-shaped steel 401, and its surface is flush with the surface of the H-shaped steel 401, and a vertical oblong hole (reserved as the operation space for assembling bolts) is provided at its center.

[0078] Further solution: As Figure 8 shown in the figure, a semi-circular notch is opened in the stiffening plate behind the inclined support mounting plate 404, which is used in cooperation with the oblong hole of the inclined support mounting plate 404 to facilitate the welding of the internal welds of the stiffening plate. The top plate 402, the transverse stiffening plate 405, the vertical plate 406 and the H-shaped steel 401 form an open box structure, and two small stiffening plates 407 are distributed on each side to enhance the structural stability of the top plate 402. A lifting lug 408 is welded in the middle and upper part of the side of the H-shaped steel 401 for hoisting and transporting the support leg 104.

[0079] The above-mentioned support components are further described as follows.

[0080] As Figure 9 shown, the inclined support 105 is assembled between the middle frame 103 and the support leg 104. The inclined support 105 includes an H-shaped steel 501 and two mounting plates 502. The H-shaped steel 501 is of a trapezoidal structure as a whole. The two mounting plates 502 are symmetrically welded to the two inclined surfaces of the H-shaped steel 501, and the two mounting plates 502 form a 90-degree angle. The inclined support 105 can be installed between any support leg 104 and the middle frame 103 to enhance the overall structural stability. It adopts a generalized and modular design, and a total of 10 pieces can be interchanged. Through holes are provided on both sides of the H-shaped steel 501 for the lifting holes during the assembly of the bench.

[0081] As Figure 9 shown, the horizontal support 106 is assembled at the lower position between two adjacent support legs 104 in a horizontal row, which is used to enhance the structural strength of the lower part of the support leg 104 and avoid lateral displacement and even structural failure caused by structural resonance. The horizontal support 106 includes a channel steel 503, two mounting plates 504 and two lifting lugs 505. The two mounting plates 504 are symmetrically welded to both sides of the channel steel 503, and the two lifting lugs 505 are respectively welded between the channel steel 503 and the mounting plates 504. The horizontal support 106 is of a concave structure as a whole. On the one hand, the lifting lug 505 strengthens the connection between the channel steel 503 and the mounting plate 504, and at the same time, the round holes opened on the plate are used as the reserved lifting holes during the assembly of the test bench.

[0082] As Figure 9 shown, the longitudinal support 107 is assembled at the middle position between two longitudinal support legs 104 located in the middle of the middle frame 103. The longitudinal support 107 includes an H-shaped steel 506 and two mounting plates 507. The two mounting plates 507 are symmetrically welded to both sides of the H-shaped steel 506. Lifting holes are provided on both sides of the H-shaped steel 506 for assisting in lifting.

[0083] The above-mentioned motor crossbeam is further described as follows.

[0084] As Figure 10As shown in the figure, the drive motor 30 is mounted on the upper layer frame 101 through the motor cross beam 108. The motor cross beam 108 is composed of a motor mounting plate 601, a cross beam mounting plate 602, and a support plate assembly (composed of two vertical plates 603 and multiple rib plates 604) located between the two; the motor mounting plate 601 is provided with an oblong hole, and the drive motor 30 is mounted on the motor mounting plate 601 through a fastener in cooperation with the oblong hole. The drive motor 30 can be longitudinally position-adjusted along the oblong hole; the cross beam mounting plate 602 straddles two parallel cross beams in the upper layer frame 101. Mounting holes are opened at both ends of the cross beam mounting plate 602, and by cooperating with the oblong holes on the cross beam through fasteners, the lateral position adjustment of the drive motor 30 is realized.

By combining different modules, crushers of different specifications and models can be adapted (changing the position of the light holes opened in the upper layer frame) to ensure sufficient load-bearing capacity and structural stability. At the same time, considering the installation and operation requirements of the crusher, the structural design includes a basic support module and a modular expansion component.

[0087] The basic support module includes a steel support structure and a fixing device. The steel support structure is welded by high-strength steel to ensure that the load-bearing requirement exceeds 100 tons. By adjusting the fixing device, crushers of different sizes can be adapted. Modular expansion components, such as additional support frames, adjusting devices, etc. These components can be easily combined with the basic support module to achieve flexible expansion of the test bench. Through precision machining and assembly, it is ensured that the support structure of the test bench has sufficient precision and stability. At the same time, necessary vibration damping measures are adopted to reduce the natural frequency of the support structure and avoid interference with the operating frequency of the crusher.

[0088] Through the above structural design, the inspection and debugging work of the single-cylinder cone crusher mainframe is transformed from the traditional "street stall" to "standardization and modularization". By simulating the actual working conditions and observing the operation of the crusher, the reliability of the lubrication system, hydraulic system, sealing device, and operating system is fully verified.
