Description

Technical Field

[0001] The utility model relates to the technical field of concrete detection, in particular to a concrete hardness detection device. Background Art

[0002] Concrete is a general term for engineering composite materials in which aggregates are bonded into a whole by cementitious materials. The term concrete usually refers to cement as the cementitious material, sand and stone as aggregates; and water (which may contain admixtures and additives) mixed in a certain proportion and obtained by stirring. Cement concrete, also known as ordinary concrete, is widely used in civil engineering. Concrete has the characteristics of abundant raw materials, low price and simple production process, which makes its usage more and more.

[0003] A search revealed a Chinese patent application with the publication number CN107807058A, which discloses a concrete hardness testing device. The device comprises a support platform and a motor, wherein support columns are fixedly connected to both sides of the top of the support platform, a gear ring is fixedly connected between the two support columns, a gear is meshed in the inner cavity of the gear ring, a first crank-connecting rod is fixedly connected to the axis of the back of the gear, the end of the first crank-connecting rod away from the gear is fixedly connected to the output end of the motor, and a second crank-connecting rod is fixedly connected to the axis of the gear surface. The concrete hardness testing device, through the arrangement of the gear ring, gear, first crank-connecting rod, motor, second crank-connecting rod, and connecting rod, jointly constructs a reciprocating structure that can drive the connecting rod to move up and down. The arrangement of the pressure plate, second sliding seat, support rod, and support plate jointly constructs a testing device. The coordination of the above structures solves the problems of high labor intensity, complex operation, and low work efficiency.

[0004] However, when testing the hardness of concrete, the downward pressure is driven by the crank movement, the impact force is limited, and there is no shielding structure, which easily causes flying stones. Utility Model Content

[0010] Preferably, the clamping plate is fixedly connected to a limiting rod, which passes through the base and is slidably connected to the base. By setting the limiting rod, the clamping plate has a limiting effect.

[0011] Preferably, a gear is fixedly connected to the rotating shaft, the gear is meshingly connected to a tooth plate, the tooth plate is slidably connected to the base, and the tooth plate is fixedly connected to a shield plate.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Example 1

[0022] like Figure 1-3 As shown, the utility model provides a concrete hardness detection device, including a base 1, a detection platform 2 is fixedly connected to the base 1, a detection mechanism 3 is connected to the base 1, and the detection mechanism 3 includes: a mounting seat 301, the mounting seat 301 is fixedly connected to the base 1, a rotating shaft 302 is rotatably connected to the mounting seat 301, a movable plate 303 is fixedly sleeved on the rotating shaft 302, and a knocking block 307 is fixedly connected to the movable plate 303.

[0023] The movable plate 303 is fixedly connected to a movable seat 308, and a movable block is movably mounted on the movable seat 308. The movable block is connected to a rope, and the rope is wound around a fixed pulley 305. The fixed pulley 305 is connected to the base 1. The other end of the rope is connected to a limit plate 304, and the limit plate 304 is fixedly connected to the base 1. By providing the fixed pulley 305, the movable plate 303 can be controlled to move by the rope.

[0024] A baffle 306 is fixedly connected to the fixed pulley 305, and a stopper is fixedly connected to the end of the rope near the limit plate 304. The rope passes through the baffle 306, but the stopper cannot pass through the baffle 306. The baffle 306 can limit the maximum displacement height of the rope end. After the rope is no longer fastened to the limit plate 304, the movable plate 303 and the knocking block 307 are no longer suspended and can be smashed towards the concrete on the testing platform 2, thereby achieving the effect of hardness testing.

[0025] In this embodiment, by setting the baffle 306, the maximum displacement height of one end of the rope can be limited. Then, after the rope is no longer fastened to the limit plate 304, the movable plate 303 and the knocking block 307 are no longer suspended, and they are smashed toward the concrete on the test platform 2, thereby achieving the effect of hardness testing.

[0026] Example 2

[0027] like Figure 1-3 As shown, based on Example 1, the present invention provides a technical solution: preferably, a fixing mechanism 4 is connected to the base 1, and the fixing mechanism 4 includes: a first chassis, the first chassis is fixedly connected to the inner cavity of the base 1, and a double-headed motor is installed inside the first chassis. The two output ends of the double-headed motor are respectively fixedly connected to screws 401 through couplings, and the outer walls of the screws 401 are threadedly connected to clamping plates 402. The provision of two clamping plates 402 can fix the concrete to be tested, preventing it from deviating after being hit by force, which would affect the testing effect.

[0028] The clamping plate 402 is fixedly connected to a limiting rod, which passes through the base 1 and is slidably connected to the base 1. By providing the limiting rod, the clamping plate 402 has a limiting effect.

By setting the shield plate 405, when the rotating shaft 302 rotates, the gear 403 can be rotated to drive the tooth plate 404 to move, and then the shield plate 405 is moved close to the detection platform 2, so as to avoid small pieces of material from injuring people in front after being hit, thereby achieving a protective effect.

[0030] In this embodiment, by setting up the shield 405, under the rotation of the rotating shaft 302, the gear 403 can be used to rotate and drive the tooth plate 404 to move, so that the shield 405 is close to the detection platform 2, avoiding small pieces of material from injuring people in front after being hit, thereby achieving a protective effect.

[0031] The working principle of this concrete hardness testing device is described in detail below.

[0032] like Figure 1-3 As shown, when in use, by controlling the double-headed motor to start, the operation of the double-headed motor drives the two mirror-set screws 401 to rotate, and under the limit of the limit rod, drives the two clamping plates 402 to approach each other, thereby achieving a fixing effect. By controlling the rope to no longer be fastened to the limit plate 304, the movable plate 303 and the knocking block 307 are no longer suspended, and they are smashed toward the concrete on the test bench 2, thereby achieving the effect of hardness testing.
