Description

Technical Field

[0001] The invention belongs to the technical field of strength detection, and specifically refers to a device for detecting the compressive strength of a material test block. Background Art

[0002] The compressive strength test of materials such as concrete, cement, ceramics, and glass often requires the materials to be made into standard test blocks, and their properties such as pressure limit are explored by applying pressure. Since most of these materials are brittle, residues will be produced when they are crushed, and the residues need to be cleaned up before the next test, otherwise the debris may be between the test block and the base plate, affecting the stress distribution of the next test block.

[0003] The rapid cleaning of debris is usually divided into two categories: "blowing" and "suction". "Suction" is not suitable for cleaning high-density solid residues, while "blowing" may cause debris to splash, which may damage the equipment if it enters the transmission part.

[0004] Other manual cleaning methods are time-consuming and labor-intensive, seriously affecting the speed of the test.

[0005] Therefore, the present invention proposes a technical solution for cleaning the debris by means of stirring and sweeping. Summary of the invention

[0006] In view of the above situation, in order to overcome the defects of the prior art, the present invention proposes a device for detecting the compressive strength of material test blocks; the transverse moving block can be pushed to move laterally through the manual opening and closing control component, and the transverse moving block can support the flexible steel plate when pressure is applied. When descending, the separation of the transverse moving block can leave a channel for the falling of debris; the lifting screw can automatically drive the bevel gear to rotate when rotating, and the rotation of the driven shaft can pull the flexible steel plate back on the one hand, and on the other hand, it can also drive the roller brush to rotate, thereby sweeping off the debris accumulated on the flexible steel plate.

[0007] The technical solution adopted by the present invention is as follows: The present invention proposes a device for detecting the compressive strength of a material test block, comprising an opening and closing base plate mechanism, a lifting component, an automatic slag falling mechanism, a reciprocating roller brush mechanism and a lifting and extrusion guide mechanism, wherein the opening and closing base plate mechanism is arranged on the lifting component, the lifting component is arranged on the lifting and extrusion guide mechanism, the automatic slag falling mechanism is arranged on the opening and closing base plate mechanism, and the reciprocating roller brush mechanism is arranged on the opening and closing base plate mechanism.

[0008] Furthermore, the opening and closing base plate mechanism includes a lifting base bracket, a transverse moving block and a manual opening and closing control component, the lifting base bracket is arranged on the lifting component, the transverse moving block is slidably arranged on the lifting base bracket, and the manual opening and closing control component is arranged on the transverse moving block.

[0009] The sliding combination and separation of two transverse blocks can be manually controlled through the opening and closing bottom plate mechanism. By rotating the dialing rocker arm, the transverse block can be slid to directly below the pressing block during the pressure test to ensure sufficient support strength for both the upper and lower pressing surfaces. After the test, separating the transverse block can create a channel for the broken slag of the test block to fall.

[0010] Preferably, a transverse guide rod is provided on the lifting base bracket, a guide groove is provided on the transverse block, the transverse guide rod is engaged and slidably arranged in the guide groove, and a sliding convex platform is provided on one side of the transverse block.

[0011] As a further preference of the present invention, the manual opening and closing control assembly includes a sliding control arm, a longitudinal slider, a longitudinal chute, and a rocker arm. The two ends of the sliding control arm are respectively hinged to the convex shaft of the longitudinal slider and the sliding convex platform. The longitudinal chute is fixedly connected to the lifting base bracket. The longitudinal slider is engaged and slidably arranged in the longitudinal chute. One end of the rocker arm is hinged to the housing, and the convex shaft of the longitudinal slider slides in the chute of the rocker arm.

[0012] Furthermore, the lifting assembly includes a lifting screw rod, a lifting nut, a nut mounting seat, and a housing. The lifting screw rod is rotatably arranged on the lifting and pressing guiding mechanism and is driven by a motor. The lifting nut is threadedly connected to the lifting screw rod. The lifting nut is fixedly connected in the nut mounting seat. The nut mounting seat is fixedly connected in the housing. The lifting base bracket is fixedly connected in the housing, and the lifting base bracket is fixedly connected to the nut mounting seat.

[0013] Through the threaded transmission between the lifting screw rod and the lifting nut, the overall lifting control of the opening and closing bottom plate mechanism can be achieved.

[0014] Furthermore, the automatic broken slag falling mechanism includes a flexible steel plate assembly and a driven assembly. The flexible steel plate assembly is arranged on the opening and closing bottom plate mechanism, and the driven assembly is arranged on the lifting assembly.

[0015] Preferably, the flexible steel plate assembly includes a flexible steel plate and a rack guide rail. One end of the flexible steel plate is provided with a return spring, and the end of the return spring is fixedly connected to the lifting base bracket. The flexible steel plate is slidably arranged on the lifting base bracket. The rack guide rail is fixedly connected to the lifting base bracket. A rack body is slidably arranged on the rack guide rail, and the rack body is fixedly connected to the other end of the flexible steel plate.

[0016] Through the transmission between the spur gear and the rack body, during the downward movement of the opening and closing bottom plate mechanism, the flexible steel plate can be slowly retracted into the opening and closing bottom plate mechanism, so that the broken slag originally placed on the flexible steel plate falls into the tray from the space between the transverse blocks, realizing the cleaning and collection of the broken slag.

[0017] As a further preference of the present invention, the driven assembly includes a driven shaft bracket disposed on the lifting assembly. A driven rotating shaft is rotatably provided on the driven shaft bracket. Straight gears are symmetrically provided at both ends of the driven rotating shaft. The straight gears are in meshing transmission with the rack body. An inclined groove gear is provided at the middle position of the driven rotating shaft.

[0018] Wherein, the inclined groove on the inclined groove gear cooperates with the spiral protrusion of the lifting screw rod. The rotational movement of the lifting screw rod relative to the inclined groove gear can drive the inclined groove gear to rotate. The lifting movement of the inclined groove gear relative to the lifting screw rod can also drive the inclined groove gear to rotate.

[0019] The rotational movement of the lifting screw rod relative to the inclined groove gear can drive the inclined groove gear to rotate, and the transmission ratio is A; the lifting movement of the inclined groove gear relative to the lifting screw rod can also drive the inclined groove gear to rotate, and the transmission ratio is B. In actual use, since the rotation of the lifting screw rod will simultaneously drive the lifting of the opening and closing bottom plate mechanism, the actual transmission ratio between the lifting screw rod and the inclined groove gear is the superposition of A and B. By separately designing A and B, the actual transmission ratio between the inclined groove gear and the lifting screw rod can be controlled.

[0020] Furthermore, the reciprocating brush mechanism includes a brush bracket disposed on the lifting base bracket. A brush rotating shaft is rotatably provided at the end of the brush bracket.

The winding sleeves are respectively provided on the brush rotating shaft and the driven rotating shaft. The linkage rope is wound around the winding sleeves. A steering guide rod is provided on the brush bracket. The linkage rope is in sliding contact with the steering guide rod.

[0022] Through the linkage of the linkage rope, when the driven rotating shaft rotates, it can simultaneously drive the brush rotating shaft to rotate.

By rotating the rocking arm, the transverse block can be slid to directly below the pressing block during the pressure test to ensure sufficient support strength for both the upper and lower pressing surfaces. After the test, separating the transverse block can leave a passage for the debris of the test block to fall.

[0025] (2) Through the screw drive between the lifting screw and the lifting nut, the overall lifting control of the opening and closing bottom plate mechanism can be achieved.

[0026] (3) Through the transmission between the spur gear and the rack body, during the descent of the opening and closing bottom plate mechanism, the flexible steel plate can be slowly retracted into the opening and closing bottom plate mechanism, so that the debris originally placed on the flexible steel plate falls into the tray through the space between the transverse blocks, realizing the cleaning and collection of the debris.

[0027] (4) The rotational movement of the lifting screw relative to the inclined groove gear can drive the inclined groove gear to rotate, and the transmission ratio is A; the lifting movement of the inclined groove gear relative to the lifting screw can also drive the inclined groove gear to rotate, and the transmission ratio is B. In actual use, since the rotation of the lifting screw will simultaneously drive the opening and closing bottom plate mechanism to lift, the actual transmission ratio between the lifting screw and the inclined groove gear is the superposition of A and B. By separately designing A and B, the actual transmission ratio between the inclined groove gear and the lifting screw can be controlled.

[0028] (5) Through the linkage of the linkage rope, when the driven rotating shaft rotates, it can simultaneously drive the rotating brush shaft to rotate. During the rotation of the rotating brush barrel, the debris accumulated on the flexible steel plate can be swept into the gap between the transverse blocks. Brief Description of the Drawings

[0039] The lifting assembly 2 includes a lifting screw rod 16, a lifting nut 17, a nut mounting seat 18, and a housing 19. The lifting screw rod 16 is rotatably arranged on the lifting and extrusion guiding mechanism 5, the lifting screw rod 16 is driven by a motor, the lifting nut 17 is threadedly connected to the lifting screw rod 16, the lifting nut 17 is fixedly connected in the nut mounting seat 18, the nut mounting seat 18 is fixedly connected in the housing 19, the lifting base bracket 6 is fixedly connected in the housing 19, and the lifting base bracket 6 is fixedly connected to the nut mounting seat 18.

[0040] Through the threaded transmission between the lifting screw rod 16 and the lifting nut 17, the overall lifting control of the split bottom plate mechanism 1 can be achieved.

[0041] The slag automatic falling mechanism 3 includes a flexible steel plate assembly 20 and a driven assembly 21. The flexible steel plate assembly 20 is arranged on the opening and closing bottom plate mechanism 1, and the driven assembly 21 is arranged on the lifting assembly 2.

[0042] The flexible steel plate assembly 20 includes a flexible steel plate 22 and a rack guide 24. One end of the flexible steel plate 22 is provided with a return spring 23, and the end of the return spring 23 is fixedly connected to the lifting base bracket 6. The flexible steel plate 22 is slidably arranged on the lifting base bracket 6. The rack guide 24 is fixedly connected to the lifting base bracket 6, and a rack body 25 is slidably arranged on the rack guide 24. The rack body 25 and the other end of the flexible steel plate 22 are fixedly connected.

[0043] Through the transmission between the spur gear 28 and the rack body 25, during the descent of the opening and closing bottom plate mechanism 1, the flexible steel plate 22 can be slowly retracted into the opening and closing bottom plate mechanism 1, so that the slag originally placed on the flexible steel plate 22 falls into the tray 37 from the space between the transverse blocks 7, realizing the cleaning and collection of the slag.

[0044] The driven assembly 21 includes a driven shaft bracket 26. The driven shaft bracket 26 is arranged on the lifting assembly 2. A driven rotating shaft 27 is rotatably arranged on the driven shaft bracket 26. Spur gears 28 are symmetrically arranged at both ends of the driven rotating shaft 27. The spur gears 28 are meshed with the rack body 25 for transmission. A slotted gear 29 is arranged at the middle position of the driven rotating shaft 27.

[0045] The slotted groove on the slotted gear 29 is matched with the spiral protrusion of the lifting lead screw 16. The rotational movement of the lifting lead screw 16 relative to the slotted gear 29 can drive the slotted gear 29 to rotate, and the lifting movement of the slotted gear 29 relative to the lifting lead screw 16 can also drive the slotted gear 29 to rotate.

[0046] The rotational movement of the lifting lead screw 16 relative to the slotted gear 29 can drive the slotted gear 29 to rotate, and the transmission ratio of this is A; the lifting movement of the slotted gear 29 relative to the lifting lead screw 16 can also drive the slotted gear 29 to rotate, and the transmission ratio of this is B. In actual use, since the rotation of the lifting lead screw 16 will simultaneously drive the lifting of the opening and closing bottom plate mechanism 1, the actual transmission ratio between the lifting lead screw 16 and the slotted gear 29 is the superposition of A and B. By separately designing A and B, the actual transmission ratio between the slotted gear 29 and the lifting lead screw 16 can be controlled.

[0047] The reciprocating brush mechanism 4 includes a brush support 30. The brush support 30 is arranged on the lifting base bracket 6. A brush rotating shaft 33 is rotatably arranged at the end of the brush support 30. A brush cylinder 34 is arranged on the brush rotating shaft 33. The brush cylinder 34 is in sliding contact with the upper surface of the flexible steel plate 22. A torsion spring for resetting is arranged between the brush rotating shaft 33 and the brush support 30.

[0048] The reciprocating roller brush mechanism 4 further includes a winding sleeve 31 and a linkage rope 32. The winding sleeve 31 is respectively arranged on the roller brush rotating shaft 33 and the driven rotating shaft 27. The linkage rope 32 is wound around the winding sleeve 31. A steering guide rod is arranged on the roller brush bracket 30, and the linkage rope 32 is in sliding contact with the steering guide rod.

[0049] Through the linkage of the linkage rope 32, when the driven rotating shaft 27 rotates, it can drive the roller brush rotating shaft 33 to rotate simultaneously. During the rotation of the roller brush cylinder 34, the crushed slag accumulated on the flexible steel plate 22 can be swept into the gap between the transverse stoppers 7.

[0050] The lifting and pressing guiding mechanism 5 includes a base 35 and a tray 37. A support column 36 is arranged on the base 35, a top platform 38 is arranged on the support column 36, a pressing block 39 is arranged at the bottom of the top platform 38, the tray 37 is placed on the base 35, and the lifting screw rod 16 is rotatably arranged in the base 35 and the top platform 38.

[0051] During specific use, in the initial state, the opening and closing bottom plate mechanism 1 is located below. At this time, by rocking the rocker arm 15, the longitudinal slider 13 is moved downward. At this time, through the linkage of the sliding control arm 12, the two transverse stoppers 7 can be made to approach the middle position until they are in contact; then the test block to be tested is placed on the transverse stoppers 7 and is roughly located below the pressing block 39. At this time, the flexible steel plate 22 is still in the retracted state; Then, by controlling the rotation of the lifting screw rod 16, the entire opening and closing bottom plate mechanism 1 can be lifted. During the lifting process, the lifting screw rod 16 will drive the slotted gear 29 to rotate; the rotational movement of the lifting screw rod 16 relative to the slotted gear 29 can drive the slotted gear 29 to rotate (similar to a worm and worm gear transmission mechanism), and this transmission ratio is A; the lifting movement of the slotted gear 29 relative to the lifting screw rod 16 can also drive the slotted gear 29 to rotate (similar to a gear and rack transmission mechanism), and this transmission ratio is B. In actual use, since the rotation of the lifting screw rod 16 will simultaneously drive the opening and closing bottom plate mechanism 1 to lift, the actual transmission ratio between the lifting screw rod 16 and the slotted gear 29 is the superposition of A and B; the transmission matching accuracy requirement between the lifting screw rod 16 and the slotted gear 29 is not high, and play is allowed as long as it can drive the slotted gear 29 to rotate.

[0052] When the opening and closing bottom plate mechanism 1 rises, through the rotation of the inclined groove gear 29 driving the driven rotating shaft 27 and the spur gear 28, the spur gear 28 will push the rack body 25 to slide upward along the rack guide 24. At this time, the flexible steel plate 22 gradually extends under the elastic force of the return spring 23. Since the middle position of the workpiece is blocked by the opening at the top of the housing 19, the end slope of the flexible steel plate 22 can smoothly insert into the bottom of the test block and separate itself between the test block and the transverse stop 7; the opening at the top of the housing 19 has a downward-bent slope, so even if a small part of the crushed slag falls above the housing 19 subsequently, it can slide down onto the flexible steel plate 22 through this slope.

[0053] When the opening and closing bottom plate mechanism 1 moves to the top, the test block contacts the pressing block 39. When continuing to apply pressure, the test block will be squeezed by the pressing block 39 at the top and the flexible steel plate 22 at the bottom. At this time, the transverse stop 7 provides support for the flexible steel plate 22. During this process, information such as the pressure change situation and the pressure value when the test block breaks can be sensed through the sensor located on the pressing block 39.

[0054] After the test is completed, the longitudinal slider 13 is pushed upward by the rocker arm 15. At this time, the transverse stop 7 will move laterally outward and separate under the linkage of the sliding control arm 12, leaving a space for the slag to fall; Then, the overall opening and closing bottom plate mechanism 1 is lowered by the reverse rotation of the lifting screw rod 16. At this time, the rotation direction of the inclined groove gear 29 is opposite to that when rising; When the inclined groove gear 29 rotates, the rack body 25 can be driven to descend through the spur gear 28, and at the same time, the flexible steel plate 22 slides back; at the same time, through the linkage of the linkage rope 32, the rotary brush shaft 33 and the rotary brush barrel 34 will also rotate simultaneously, and the rotation direction of the rotary brush barrel 34 has the effect of pushing the slag accumulated on the flexible steel plate 22 outward to prevent the slag from adhering to the flexible steel plate 22.

[0055] When descending, the rotation of the rotary brush shaft 33 will cause the torsion spring to deform and accumulate elastic force. Therefore, during the rising stage, the rotary brush shaft 33 can rotate back to its original position and keep the linkage rope 32 taut.

[0056] During the retraction process of the flexible steel plate 22, first, the slag will move along with the flexible steel plate 22 and accumulate at a position close to the rotary brush barrel 34. In the final stage of the retraction of the flexible steel plate 22, that is, when the opening and closing bottom plate mechanism 1 has descended to a lower position, the slag will fall from the flexible steel plate 22 into the tray 37; the fallen slag falls into the tray 37 and can be cleaned in time.

[0057] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.

[0058] The above describes the present invention and its embodiments. Such description is not restrictive. What is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. In general, if those of ordinary skill in the art are inspired by it and, without departing from the spirit of the present invention, design similar structural forms and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present invention.
