Description

Technical Field

[0001] The utility model belongs to the technical field, and in particular relates to a building concrete on-site construction strength detection device. Background Art

[0002] Concrete refers to a mixture of binder, granular aggregate, water, and chemical admixtures and mineral admixtures that need to be added in appropriate proportions, or a composite material with a stacking structure formed after hardening. Concrete is widely used in construction and civil engineering. During the use of buildings, in order to ensure the structural strength, the concrete used needs to be tested. The standard pressure test method is one of the most commonly used methods. The strength of concrete is evaluated by using standard specimens to conduct compressive strength tests under standard curing conditions. The specimens are placed on a press, and a standard load is applied to determine their compressive strength. When using the existing concrete strength tester, the operator needs to reach into the machine, place the concrete block on the pressure platform, and start the pressure test. The feed is relatively unchanged, and the concrete debris will scatter and splash after pressure, which is not easy to clean and sweep. Based on this, we designed a concrete testing device that can facilitate the discharge and feeding of materials to improve the convenience of testing. Utility Model Content

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0025] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. 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.

[0026] like Figure 2 , Figure 5 and Figure 6As shown, the on-site construction strength detection device of building concrete includes a fixed base 1, a connecting pillar 5, a connecting platform 6, a detection mechanism 3, a feeding mechanism 2 and a controller 4. The upper part of the fixed base 1 is connected to the connecting platform 6 through the connecting pillar 5, and the upper part of the connecting platform 6 is provided with a detection mechanism 3; the detection mechanism 3 includes a guide support 302, a driving rod 309, a gear 303, a lower pressure rod 305 and a pressure plate 306, and the two sides of the driving rod 309 are movably connected with the sliding groove on the inner wall of the guide support 302 through a sliding bar 311, and the rack 310 on one side of the driving rod 309 is meshed with the gear 303; the lower pressure rod One end of 305 is connected with the pressure plate 306 through the lower pressure rod 305, and the upper part of the lower pressure rod 305 is provided with a propulsion rod 308 and a travel switch 307; the upper part of the fixed base 1 is provided with a propulsion bracket and a detection mechanism 3; the gear 303 is arranged on a fixed block on one side of the guide support 302, and the rotating shaft on the gear 303 is connected to the driving motor 304 through a coupling; the upper part of the pressure plate 306 is movably connected with the through hole inside the lower pressure rod 305 through a connecting rod 312, and a pressure spring is arranged inside the through hole; the side of the pressure plate 306 is arranged corresponding to the travel switch 307 on the outer wall of the lower pressure rod 305 through the propulsion rod 308.

[0027] It should be noted that the existing concrete testing instruments generally use manual feeding to place concrete directly, placing the entire concrete on the pressure platform, and the space around the pressure platform is relatively narrow, which is inconvenient when placing, especially when the volume of concrete to be tested is large, it is extremely inconvenient. Therefore, we have designed a feeding mechanism 2 on the upper part of the fixed base 1 to realize the external placement and installation of concrete blocks. After placement, it is pushed by the first electric push cylinder 211 to realize automatic feeding.

[0028] It should be further explained that a detection mechanism 3 is provided on the upper part of the connecting platform 6 , and the driving rod 309 is driven to rise and fall through the gear 303 , thereby pressing the entire pressure plate 306 downward, and the concrete block on the loading disc 206 is subjected to pressure detection.

[0029] It should be further explained that the pressure plate 306 is connected to the through hole of the lower pressure rod 305 through the connecting rod 312, and a pressure spring is arranged inside the through hole of the lower pressure rod 305, which can be an elastic structure. During the downward pressure process, the pressure plate 306 can retract after contacting the concrete. During the retraction process, the pushing rod 308 is pushed to contact the travel switch 307, which can trigger the travel switch 307 and open the protection group. The advantage of this design is that the protection group can be opened after the pressure plate 306 contacts the concrete, which will not affect the entire detection process.

[0030] like Figure 2-Figure 4As shown, the feeding mechanism 2 includes a moving platform 201, a material trough 202, a connecting base 205, a loading disc 206, a propulsion group and a protection group. The moving platform 201 is arranged on the upper part of the propulsion bracket, and the material trough 202 and the connecting base 205 are arranged on the moving platform 201; the connecting base 205 is movably connected to the second guide groove 212 inside the material trough 202 through the connecting group on the side, and the loading disc 206 is arranged on the upper part of the connecting base 205; a plurality of guide wheels 210 are arranged at the bottom of the propulsion bracket, and the guide wheels 210 are arranged in the first guide groove 10 of the fixed base 1.

[0031] It should be noted that for the convenience of feeding, we have set up an independent feeding mechanism 2, which can place the concrete outside and send it to the detection mechanism 3 for detection. When in use, for the convenience of placement, we set a loading disc 206 inside the trough 202 for storing concrete. In addition, for the convenience of feeding, we set the entire trough 202 on the upper part of the propulsion bracket, and cooperate with the first electric push cylinder 211 for propulsion.

[0032] like Figure 3 and Figure 4 As shown, the connection group includes a telescopic rod 207 and a rotating wheel 208, one end of the telescopic rod 207 is fixedly connected to the connecting base 205, and the other end of the telescopic rod 207 is provided with a rotating wheel 208, and the rotating wheel 208 is arranged in contact with the second guide groove 212; the protection group includes a protective plate 204 and a second electric push cylinder 203, the second electric push cylinder 203 is symmetrically arranged on the side wall of the material trough 202, and a protective plate 204 is arranged on the output shaft of the second electric push cylinder 203.

[0033] It should be noted that when concrete is being tested, pressure must be applied to align it. In the present technical solution, the entire trough 202 is arranged on the propulsion bracket. If pressure is applied directly, the entire pressure will be transmitted to the guide wheel 210, causing damage to it. Therefore, the entire trough 202 is a rectangular hollow structure with upper and lower openings. A connecting base 205 is provided at the lower part of the loading disc 206. The side of the connecting base 205 is connected to the second guide groove 212 on the inner wall of the trough 202 through a connecting group. The advantage of this design is that after the propulsion bracket is pushed, the entire connecting base 205 can be lifted by the third electric push cylinder 8, which plays a role of auxiliary support, offsets the pressure, and protects the propulsion bracket.

[0034] It should be further explained that the side of the connecting base 205 is connected to the second guide groove 212 through the telescopic rod 207 and the rotating wheel 208, and a pressure spring is arranged on the outer wall of the telescopic rod 207 to form an elastic structure. The advantage of this design is that when the connecting base 205 is lifted, the rotating wheel 208 on the telescopic rod 207 can assist in movement in the second guide groove 212, making the lifting process smoother.

[0035] like Figure 3 and Figure 4 As shown, the protection group includes a protection plate 204 and a second electric push cylinder 203, the second electric push cylinder 203 is symmetrically arranged on the side wall of the material trough 202, and the protection plate 204 is arranged on the output shaft of the second electric push cylinder 203; the propulsion group includes a third electric push cylinder 8 and a lifting plate 9, the third electric push rod 8 is arranged at the bottom of the fixed base 1, and the output end of the third electric push cylinder 8 is connected to the lifting plate 9.

[0036] It should be noted that during the advancement of the advancement bracket, the concrete will shift due to movement, resulting in falling off during the downward pressure detection. In order to overcome this problem, we set a protective plate 204 and a second electric push cylinder 203 on the upper part of the trough 202. After the concrete is placed, the second electric push cylinder 203 is started and fixed by the protective plates 204 at both ends. In addition, in order to enable the pressure plate 306 in the detection mechanism 3 to contact the concrete block when the pressure plate 306 is pressed down, the protective plate 204 can retract. Therefore, a thrust rod 308 is set on the upper part of the pressure plate 306. During the downward pressure of the pressure plate 306, the connecting rod 312 will retract inside the downward pressure rod 305. At this time, the thrust rod 308 is connected to the travel switch 307, and the control box controls the retraction of the second electric push cylinder 203 to achieve coordination.

[0037] like Figure 1 and Figure 2 As shown, one end of the moving platform 201 is connected to the first electric push cylinder 211 through a connecting piece; and a controller 4 is provided at one end of the connecting platform 6 .

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
