[0014] A further technical solution is: the third driving device is a motor.

[0015] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0016] 1. Due to the use of the base, test bench, support rollers, lifting mechanism, sliding device, positioning mechanism, limit holes and rectangular openings, when the mechanical equipment needs to be tested, the mechanical equipment is first placed on the top of the test bench by a crane. At this time, each set of support rollers on the test bench will be supported at the bottom of the mechanical equipment, and then the positioning mechanism starts to work, so that the positioning mechanism pushes the mechanical equipment to move on the test bench. When the center of the circle of the mechanical equipment matches the center of the circle of the test bench, the two ends of the positioning mechanism are clamped at the two ends of the mechanical equipment, so that the position of the mechanical equipment on the test bench is limited. When the height of the mechanical equipment needs to be adjusted, the staff drives the first threaded rod to rotate through the output shaft of the second drive device in the sliding device, so that the two sets of first sliders slide close to each other or slide away from each other at the same time along the two sets of limit slide rails. When the two groups of first slide blocks move to the bottom of two groups of rectangular openings, the driving ends of the first drive devices in the two groups of lifting mechanisms extend out at the same time, so that the two groups of lifting plates extend out from the two groups of rectangular openings at the same time. At this time, the two groups of lifting plates are against the bottom of the mechanical equipment and drive the mechanical equipment to lift and lower. At this time, the height of the mechanical equipment can be adjusted. The whole operation process is simple and reliable, which is convenient for the staff to operate and can make it more convenient for the staff to inspect the mechanical equipment. Since the inspection table is provided with four groups of rectangular openings arranged in a linear array, and the spacing between the two groups of lifting mechanisms can be adjusted according to the rotation of the first threaded rod driven by the output shaft of the second drive device, the two groups of lifting mechanisms can lift and adjust the height of mechanical equipment of different models and sizes, thereby greatly improving the practicality of the mechanical equipment safety inspection mechanism when in use.

[0017] 2. Due to the use of the arrangement of the abutment device, the second slider, the second threaded rod, the support rail, the second bearing seat and the third driving device, the output shaft of the third driving device drives the second threaded rod to rotate. Since the second threaded rod is threaded with two sets of second sliders, and the two sets of second sliders slide on the support rail, when the output shaft of the third driving device drives the second threaded rod to rotate, the two sets of second sliders will slide close to or away from the support rail at the same time, thereby enabling the two sets of abutment devices to move close to or away from the surface of the test bench at the same time. When the mechanical equipment is placed on the test bench, the output shaft of the third driving device drives the second threaded rod to rotate, so that the two sets of second sliders carry the corresponding abutment devices and slide close to the mechanical equipment along the surface of the test bench. The movement of the two sets of abutment devices can adjust the position of the mechanical equipment placed on the test bench, and the position of the mechanical equipment can be positioned, thereby ensuring the stability of the mechanical equipment on the test bench. Since the distance between the two sets of abutment devices can be automatically adjusted according to the output shaft of the third drive device driving the second threaded rod to rotate, mechanical equipment of different models and sizes can be positioned between the two sets of abutment devices.

[0018] 3. Due to the use of the bending rod, baffle, spring and second telescopic rod, when the two sets of abutting devices abut against both ends of the mechanical equipment at the same time, the baffles in the two sets of abutting devices will contact the mechanical equipment, and the mechanical equipment will generate a certain extrusion force on the two sets of baffles, so that the two sets of baffles compress the corresponding springs and the second telescopic rod respectively. At this time, the spring in a compressed state will generate a reaction force on the corresponding baffle, so that the baffle can play a certain buffering role on the mechanical equipment, and thus can play a protective effect on the mechanical equipment. When the spring is in a compressed state, the second telescopic rod can prevent the spring from deforming, and thus can play a certain protective role on the spring.

[0019] 4. Due to the setting of the damping block, when the baffle is against the mechanical equipment, the damping block on the baffle will contact the mechanical equipment. At this time, the damping block will increase the friction between the baffle and the mechanical equipment, so that when the two sets of baffles are against the two sides of the mechanical equipment, the positioning effect of the mechanical equipment will be better.

DETAILED DESCRIPTION

[0026] The embodiment of the present application provides a mechanical equipment safety inspection mechanism, which solves the technical problem that in the existing technical solutions, the height adjustment of mechanical equipment mostly relies on external lifting equipment or jacking equipment, which makes the operation extremely cumbersome and inconvenient for detection work.

[0027] The technical solution in the embodiment of the present application is to solve the above problems, and the overall idea is as follows:

[0028] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0029] A mechanical equipment safety inspection organization, such as Figure 1 , Figure 2 and Figure 3 As shown, it includes a base 1, a test platform 2 arranged on the base 1, a support roller 3 for supporting mechanical equipment, a lifting mechanism 4 for lifting the mechanical equipment, a sliding device 5 for driving the lifting mechanism 4 to slide, and a positioning mechanism 6 for positioning the position of the mechanical equipment. The test platform 2 is provided with a plurality of groups of limiting holes 21 arranged in a rectangular array. Each group of limiting holes 21 is rotatably connected to the support roller 3. The sliding device 5 and the positioning mechanism 6 are both arranged on the base 1, and the sliding device 5 is located directly below the test platform 2. Two groups of lifting mechanisms 4 arranged symmetrically are arranged on the sliding end of the sliding device 5.

[0030] The lifting mechanism 4 includes a lifting plate 41 for supporting the mechanical equipment, a first driving device 42 for driving the lifting plate 41 to rise and fall, and a first telescopic rod 43 for limiting the lifting and falling of the lifting plate 41. The first driving device 42 is arranged on the sliding end of the sliding device 5, and the lifting plate 41 is arranged on the driving end of the first driving device 42. Two groups of first telescopic rods 43 symmetrically arranged with the first driving device 42 are arranged on the sliding end of the sliding device 5, and the telescopic ends of the two groups of first telescopic rods 43 are connected to the lifting plate 41. Four groups of rectangular openings 22 arranged in a linear array are provided on the testing platform 2. When the driving end of the first driving device 42 is extended, the lifting plate 41 can extend from one of the rectangular openings 22 corresponding to the first driving device 42.

[0031] The sliding device 5 includes a first slider 51, a first threaded rod 52 for driving the first slider 51 to move, a limiting slide rail 53 for limiting the movement of the first slider 51, a second driving device 54 for driving the first threaded rod 52 to rotate, and a first bearing seat 55 installed on the base 1. Two groups of first sliders 51 symmetrically placed are threadedly connected to the first threaded rod 52. Two groups of limiting slide rails 53 symmetrically placed are arranged on the base 1. Both groups of first sliders 51 slide on the two groups of limiting slide rails 53. Both groups of first sliders 51 are provided with a first driving device 42 and a first telescopic rod 43. One end of the first threaded rod 52 is arranged on the output shaft of the second driving device 54. The other end of the first threaded rod 52 is arranged on the inner ring of the bearing in the first bearing seat 55. The second driving device 54 is installed on the base 1. When the output shaft of the second driving device 54 drives the first threaded rod 52 to rotate, the two groups of first sliders 51 will slide close to or away from each other along the two groups of limiting slide rails 53 at the same time.

[0032] The test bench 2 is fixedly connected to the top of the base 1. The support roller 3 is preferably made of rubber. The sliding device 5 and the positioning mechanism 6 are both fixedly connected to the top of the base 1, and the sliding device 5 is located directly below the test bench 2. Two groups of symmetrically placed lifting mechanisms 4 are fixedly connected to the sliding end of the sliding device 5. The first drive device 42 is preferably a cylinder. The first drive device 42 is fixedly connected to the sliding end of the sliding device 5, and the lifting plate 41 is fixedly connected to the driving end of the first drive device 42. Two groups of first telescopic rods 43 symmetrically placed with the first drive device 42 are fixedly connected to the sliding end of the sliding device 5, and the telescopic ends of the two groups of first telescopic rods 43 are fixedly connected to the bottom of the lifting plate 41. The first bearing seat 55 is fixedly connected to the top of the base 1. Two groups of symmetrically placed limiting slide rails 53 are fixedly connected to the top of the base 1. The first drive device 42 and the first telescopic rod 43 are fixedly connected to the two groups of first sliders 51. One end of the first threaded rod 52 is fixedly connected to the output shaft of the second drive device 54. The second drive device 54 is preferably a motor. The other end of the first threaded rod 52 is fixedly connected to the inner ring of the bearing in the first bearing seat 55. The second driving device 54 is fixedly installed on the top of the base 1. When the output shaft of the second driving device 54 drives the first threaded rod 52 to rotate, the two sets of first sliders 51 will slide close to each other or slide away from each other along the two sets of limit slide rails 53 at the same time.

[0033] Due to the arrangement of the base 1, the inspection table 2, the support rollers 3, the lifting mechanism 4, the sliding device 5, the positioning mechanism 6, the limiting hole 11 and the rectangular opening 21, when the mechanical equipment needs to be inspected, the mechanical equipment is first placed on the top of the inspection table 2 by a crane, at which time each set of support rollers 3 on the inspection table 2 will be supported at the bottom of the mechanical equipment, and then the positioning mechanism 6 starts to work, so that the positioning mechanism 6 pushes the mechanical equipment to move on the inspection table 2, and when the center of the circle of the mechanical equipment matches the center of the circle of the inspection table 2, the two ends of the positioning mechanism 6 are clamped at the two ends of the mechanical equipment, so that the position of the mechanical equipment on the inspection table 2 is limited. When the height of the mechanical equipment needs to be adjusted, the staff drives the first threaded rod 52 to rotate through the output shaft of the second drive device 54 in the sliding device 5, so that the two sets of first sliders 51 slide close to each other or slide away from each other simultaneously along the two sets of limiting slide rails 53. When the two groups of first slide blocks 51 move to the right below the two groups of rectangular openings 21, the first drive devices 42 driving ends of the two groups of lifting mechanisms 4 extend out at the same time, so that the two groups of lifting plates 41 extend out from the two groups of rectangular openings 22 at the same time. At this time, the two groups of lifting plates 41 abut against the bottom of the mechanical equipment and drive the mechanical equipment to lift and lower. At this time, the height of the mechanical equipment can be adjusted. The whole operation process is simple and reliable, which is convenient for the staff to operate and can make it more convenient for the staff to test the mechanical equipment. Since the test bench 2 is provided with four groups of rectangular openings 22 arranged in a linear array, and the spacing between the two groups of lifting mechanisms 4 can be adjusted according to the rotation of the first threaded rod 52 driven by the output shaft of the second drive device 54, the two groups of lifting mechanisms 4 can lift and adjust the height of mechanical equipment of different models and sizes, thereby greatly improving the practicality of the mechanical equipment safety inspection mechanism when in use.

[0034] like Figure 4 As shown, the positioning mechanism 6 includes a supporting device 61 for positioning the position of the mechanical equipment, a second slider 62 for driving the supporting device 61 to move, a second threaded rod 63 for driving the second slider 62 to move, a supporting rail 64 installed on the base 1, a second bearing seat 65 arranged on the base 1, and a third driving device 66 for driving the second threaded rod 63 to rotate. Two groups of second sliders 62 symmetrically placed are threadedly connected to the second threaded rod 63. Both groups of second sliders 62 slide on the supporting rail 64. Both groups of second sliders 62 are provided with the supporting device 61. One end of the second threaded rod 63 is arranged on the output shaft of the third driving device 66. The other end of the second threaded rod 63 is arranged on the inner ring of the bearing in the second bearing seat 65. The third driving device 66 is installed on the base 1. When the output shaft of the third driving device 66 drives the second threaded rod 63 to rotate, the two groups of second sliders 62 will slide close to or away from each other along the supporting rail 64 at the same time.

[0035] The support rail 64 is fixedly connected to the top of the base 1. The second bearing seat 65 is fixedly connected to the top of the base 1. The two sets of second sliders 62 are fixedly connected with the abutment device 61. One end of the second threaded rod 63 is fixedly connected to the output shaft of the third drive device 66. The third drive device 66 is preferably a motor. The other end of the second threaded rod 63 is fixedly connected to the inner ring of the bearing in the second bearing seat 65. The third drive device 66 is fixedly installed on the top of the base 1.

[0036] Due to the arrangement of the abutment device 61, the second slider 62, the second threaded rod 63, the supporting rail 64, the second bearing seat 65 and the third driving device 66, the second threaded rod 63 is driven to rotate by the output shaft of the third driving device 66. Since two groups of second sliders 62 are threadedly connected to the second threaded rod 63, and the two groups of second sliders 62 slide on the supporting rail 64, when the output shaft of the third driving device 66 drives the second threaded rod 63 to rotate, the two groups of second sliders 62 will slide close to each other or away from each other along the supporting rail 64 at the same time, thereby enabling the two groups of abutment devices 61 to move close to each other or away from each other at the same time along the surface of the detection table 2. When the mechanical device is placed on the testing platform 2, the output shaft of the third driving device 66 drives the second threaded rod 63 to rotate, so that the two sets of second sliders 62 carry the corresponding abutment devices 61 to slide toward the mechanical device along the surface of the testing platform 2, and the position of the mechanical device placed on the testing platform 2 can be adjusted by moving the two sets of abutment devices 61, and the position of the mechanical device can be positioned, thereby ensuring the stability of the mechanical device on the testing platform 2. Since the spacing between the two sets of abutment devices 61 can be automatically adjusted according to the rotation of the second threaded rod 63 driven by the output shaft of the third driving device 66, mechanical devices of different models and sizes can be positioned between the two sets of abutment devices 61.

[0037] like Figure 5 As shown, the abutting device 61 includes a bending rod 611, a baffle 612 for abutting against the mechanical equipment, a spring 613 for buffering the baffle 612, and a second telescopic rod 614 for limiting the spring 613. The bending rod 611 is arranged on the second slider 62. The bending rod 611 is provided with a plurality of groups of second telescopic rods 614 arranged in a linear array. The telescopic ends of each group of second telescopic rods 614 are connected to the baffle 612. The outer side of each group of second telescopic rods 614 is surrounded by a spring 613. One end of each group of springs 613 is connected to the bending rod 611. The other end of each group of springs 613 is connected to the baffle 612.

[0038] The bending rod 611 is fixedly connected to the second slider 62. A plurality of groups of second telescopic rods 614 arranged in a linear array are fixedly connected to the bending rod 611. The telescopic end of each group of second telescopic rods 614 is fixedly connected to the baffle 612. One end of each group of springs 613 is fixedly connected to the bending rod 611. The other end of each group of springs 613 is fixedly connected to the baffle 612.

[0039] Due to the arrangement of the bent rod 611, the baffle 612, the spring 613 and the second telescopic rod 614, when the two groups of abutting devices 61 abut against both ends of the mechanical device at the same time, the baffles 612 in the two groups of abutting devices 61 will contact the mechanical device, and the mechanical device will generate a certain extrusion force on the two groups of baffles 612, so that the two groups of baffles 612 compress the corresponding springs 613 and the second telescopic rod 614 respectively, and the springs 613 in the compressed state will generate a reaction force on the corresponding baffles 612, so that the baffles 612 can play a certain buffering role on the mechanical device, thereby playing a protective effect on the mechanical device. When the spring 613 is in a compressed state, the second telescopic rod 614 can prevent the spring 613 from being deformed, thereby playing a certain protective role on the spring 613.

[0040] like Figure 5 As shown, the abutting device 61 further includes a damping block 615. The baffle plate 612 is provided with a plurality of groups of damping blocks 615 arranged in a linear array.

[0041] A plurality of groups of damping blocks 615 arranged in a linear array are fixedly connected to the baffle 612 .

[0042] Due to the setting of the damping block 615, when the baffle 612 abuts against the mechanical equipment, the damping block 615 on the baffle 612 will contact the mechanical equipment. At this time, the damping block 615 will increase the friction between the baffle 612 and the mechanical equipment, thereby enabling the two groups of baffles 612 to abut against both sides of the mechanical equipment, thereby providing a better positioning effect for the mechanical equipment.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.

[0044] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention.
