Description

Technical Field

[0001] This utility model relates to the field of concrete testing technology, specifically a rapid testing device for concrete material quality. Background Technology

[0002] Concrete is one of the most important building materials in modern civil engineering. Testing the strength of concrete is very important during construction. The most common method is to make concrete test blocks on site and use the cubic compressive strength to evaluate the strength of concrete.

[0003] A search revealed a utility model with Chinese patent publication number CN213600491U, which discloses a material strength testing device for building concrete production. The device includes a base, a protective cover on the upper surface of the base, a pressure testing machine fixedly mounted on the upper end of the base, a first groove in the center of the upper end of the base, and a lower pressure plate movably mounted in the first groove. This utility model incorporates a lower pressure plate, a material receiving funnel, a cover plate, and other related structures.

[0004] The device uses a scraper to clean residue. However, during long-term use, due to the combined effects of various factors, the adhesion precision between the scraper and the lower surface of the pressure plate will gradually decrease, making accurate adhesion impossible and ultimately resulting in unsatisfactory cleaning results. Utility Model Content

[0005] The purpose of this invention is to provide a rapid testing device for concrete material quality to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rapid concrete material quality testing device, comprising a workbench, a cleaning assembly mounted on the top of the workbench, the cleaning assembly comprising a support frame fixedly connected to the outer wall of the top of the workbench, two horizontally arranged guide rods fixedly connected inside the support frame, the two guide rods slidably fitted with the same mounting rod, two vertically arranged bidirectional screw rods rotatably connected inside the mounting rod, two limiting rods fixedly connected to the top and bottom inner walls of the mounting rod, two adjacent limiting rods slidably fitted with the same mounting seat, the two bidirectional screw rods respectively threadedly connected to the two mounting seats, a vertically arranged hydraulic cylinder mounted on the outer wall of the top of the workbench via a support frame, and a horizontally arranged pressure plate fixedly connected to the output end of the hydraulic cylinder.

[0007] As a further preferred embodiment of this technical solution, the top and bottom outer walls of the mounting rod end are each rotatably connected to a worm gear via a support base, and both bidirectional lead screws are coaxially fixed with a worm wheel, with the two worm gears meshing with the two worm wheels respectively.

[0008] As a further preferred embodiment of this technical solution, two scrapers are installed on the outside of each of the two mounting bases, and the two scrapers are arranged symmetrically, with the two top scrapers fitting against the bottom of the pressure plate.

[0009] The position of the scraper can be adjusted according to specific circumstances to ensure that the scraper fits tightly against the scraper plate and the receiving frame. This avoids insufficient fit affecting the cleaning effect. Grasp the mounting rod and push it to one side. The mounting rod slides along the guide rod. The mounting rod drives the scraper to move synchronously through the mounting seat. The scraper can clean the impurities attached to the bottom wall of the pressure plate and the top wall of the receiving frame and push them to one side. If the position of the scraper changes, the worm gear is driven to rotate by the knob. The worm gear drives the double-acting screw to rotate through the worm wheel meshing with it. The mounting seat sleeved outside the limit rod cannot rotate. Rotating the double-acting screw will drive the mounting seat to move upward, ensuring that the scraper on it fits perfectly against the pressure plate and the receiving frame.

[0010] As a further preferred embodiment of this technical solution, a receiving frame is slidably inserted into the top of the workbench, a pressure sensor is provided between the receiving frame and the workbench, and the two scrapers at the bottom are both in contact with the top wall of the receiving frame.

[0011] As a further preferred embodiment of this technical solution, a protective component is installed on the outside of the pressure plate. The protective component includes a drive rod fixedly installed on the top outer wall of the pressure plate, a horizontally arranged mounting shaft fixedly connected to the outside of the hydraulic cylinder support frame, a vertically arranged baffle rotatably connected to the outside of the mounting shaft, a sliding groove being opened inside the baffle, and the drive rod being inserted into the sliding groove.

[0012] When the pressure plate moves downward under the action of the drive device, the drive rod at the top of it will move synchronously. Since the chute is designed to be long and narrow, the drive rod can slide smoothly in the chute. As the drive rod slides, it will drive the baffle to rotate around the installation axis. Once the baffle has rotated, the front of the concrete material will be blocked, thereby effectively preventing small fragments from flying out due to the cracking of the concrete material and ensuring the personal safety of the workers.

[0013] As a further preferred embodiment of this technical solution, the workbench is provided with an avoidance groove, which is located directly below the protective component.

[0014] As a further preferred embodiment of this technical solution, the outer wall edges of the pressure plate and the receiving frame that are close to each other are both set to be arc-shaped, and the arc-shaped edges are parallel to the scraper.

[0015] This utility model provides a rapid testing device for concrete material quality, which has the following beneficial effects:

[0016] (1) By setting up a cleaning component, the position of the scraper can be adjusted according to the specific situation, so as to ensure that the scraper can fit tightly against the scraper and the receiving frame, and avoid insufficient fit affecting the cleaning effect. Grab the mounting rod and push it to one side. The mounting rod slides along the guide rod. The mounting rod drives the scraper to move synchronously through the mounting seat. The scraper can clean the impurities attached to the bottom wall of the pressure plate and the top wall of the receiving frame and push them to one side. If the position of the scraper changes, the worm can be rotated by the knob. The worm can drive the double screw to rotate through the worm wheel meshing with it. The mounting seat sleeved outside the limit rod cannot rotate. Rotating the double screw can drive the mounting seat to move upward, ensuring that the scraper on it can fit perfectly against the pressure plate and the receiving frame.

[0017] (2) By setting up a protective component, when the pressure plate moves downward under the action of the driving device, the driving rod at the top of it will move synchronously. Since the slide is designed as a long strip, the driving rod can slide smoothly in the slide. As the driving rod slides, it will drive the baffle to rotate around the installation axis. Once the baffle has rotated, the front of the concrete material will be blocked, thereby effectively preventing small fragments from flying out due to the cracking of the concrete material and ensuring the personal safety of the workers.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] This utility model provides a technical solution: such as Figure 1 , Figure 2 As shown in Figure 4, in this embodiment, a rapid concrete material quality testing device includes a workbench 1. A cleaning component 6 is installed on the top of the workbench 1. The cleaning component 6 includes a support frame 608 fixedly connected to the outer wall of the top of the workbench 1. Two horizontally arranged guide rods 609 are fixedly connected inside the support frame 608. The two guide rods 609 are slidably sleeved on the same mounting rod 601. Two vertically arranged bidirectional screw rods 602 are rotatably connected inside the mounting rod 601. Two limiting rods 603 are fixedly connected to the inner walls of the top and bottom of the mounting rod 601. The two mutually close limiting rods 603 are slidably sleeved on the same mounting seat 606. The two bidirectional screw rods 602 are respectively threaded into the two mounting seats 606. A vertically arranged hydraulic cylinder 3 is installed on the outer wall of the top of the workbench 1 through a support frame. A horizontally arranged pressure plate 4 is fixedly connected to the output end of the hydraulic cylinder 3.

[0025] The top and bottom outer walls of the mounting rod 601 are rotatably connected to a worm gear 605 via a support base. Two bidirectional lead screws 602 are coaxially fixed with a worm wheel 604, and the two worm gears 605 mesh with the two worm wheels 604 respectively.

[0026] Two scrapers 607 are mounted on the outside of each of the two mounting bases 606, and the two scrapers 607 are symmetrically arranged so that the scrapers 607 can also play a role when pulled back. The two top scrapers 607 are in contact with the bottom of the pressure plate 4.

[0027] Grasp the mounting rod 601 and push it to one side. The mounting rod 601 slides along the guide rod 609. The mounting rod 601 drives the scraper 607 to move synchronously through the mounting seat 606. The scraper 607 can clean the impurities attached to the bottom wall of the pressure plate 4 and the top wall of the receiving frame 5 and push them to one side. If the position of the scraper 607 changes, the worm gear 605 is driven to rotate by the knob. The worm gear 605 drives the double-acting screw 602 to rotate through the worm wheel 604 that meshes with it. The mounting seat 606, which is sleeved outside the limit rod 603, cannot rotate. Rotating the double-acting screw 602 can drive the mounting seat 606 to move upward, ensuring that the scraper 607 on it can fit perfectly with the pressure plate 4 and the receiving frame 5. This eliminates the need for excessive cleaning time and improves testing efficiency.

[0028] like Figure 1 As shown in Figure 2, a support frame 5 is slidably inserted into the top of the worktable 1, and a pressure sensor (preferably model: TE Connectivity MS5837-30BA) is installed between the support frame 5 and the worktable 1.

[0029] The two scrapers 607 at the bottom are both in contact with the top wall of the support frame 5. The pressure is applied to the pressure sensor through the support frame 5. The sensor converts the pressure signal into a usable electrical signal according to the piezoresistive effect. The electrical signal is transmitted to the external display device for processing.

[0030] like Figure 1 and Figure 3 As shown, a protective component 7 is installed on the outside of the pressure plate 4. The protective component 7 includes a drive rod 703 fixedly installed on the top outer wall of the pressure plate 4, a horizontally arranged mounting shaft 701 fixedly connected to the outside of the hydraulic cylinder 3 support frame, a vertically arranged baffle 702 rotatably connected to the outside of the mounting shaft 701, a slide groove 704 is opened inside the baffle 702, and the drive rod 703 is inserted into the slide groove 704.

[0031] When the pressure plate 4 moves downward under the action of the drive device, the drive rod 703 at its top will move synchronously. Since the slide 704 is designed to be long and narrow, the drive rod 703 can slide smoothly in the slide 704. As the drive rod 703 slides, it will drive the baffle 702 to rotate around the mounting shaft 701. Once the baffle 702 has rotated, the front of the concrete material will be blocked, thereby effectively preventing small fragments from flying out due to the cracking of the concrete material and ensuring the personal safety of the workers.

[0032] like Figure 1 As shown, the workbench 1 has an clearance groove 2 inside, which is located directly below the baffle 702, so that the movement of the baffle 702 is not blocked by the workbench 1.

[0033] like Figure 2 As shown, the outer wall edges of the pressure plate 4 and the receiving frame 5, which are close to each other, are both set to be arc-shaped, and the arc-shaped edges are parallel to the scraper 607, so as to avoid the deformation of the corner position of the two from affecting the movement of the scraper 607.

[0034] This utility model provides a rapid testing device for concrete material quality, the specific working principle of which is as follows:

[0035] When the device is working, the concrete material to be tested is placed on top of the receiving frame 5. Then, the hydraulic cylinder 3 is activated to drive the pressure plate 4 to squeeze the concrete material. The pressure acts on the pressure sensor through the receiving frame 5. The sensor converts the pressure signal into a usable electrical signal based on the piezoresistive effect. The electrical signal is transmitted to an external display device for processing. When the pressure plate 4 moves downward under the action of the driving device, the drive rod 703 at its top moves synchronously. Given that the slide 704 is designed as a long strip, the drive rod 703 can slide smoothly within the slide 704. As the drive rod 703 slides, it drives the baffle 702 to rotate around the mounting shaft 701. Once the baffle 702 has rotated, the front of the concrete material is blocked, effectively preventing small fragments from flying out due to the concrete material cracking, ensuring the personal safety of the personnel, and allowing large pieces of material to be removed. Then, grasp the mounting rod 601 and push it to one side. The mounting rod 601 slides along the guide rod 609. The mounting rod 601 drives the scraper 607 to move synchronously through the mounting seat 606. The scraper 607 can clean the impurities attached to the bottom wall of the pressure plate 4 and the top wall of the receiving frame 5 and push them to one side. If the position of the scraper 607 changes, the worm gear 605 is driven to rotate by the knob. The worm gear 605 drives the double-acting screw 602 to rotate through the worm wheel 604 meshing with it. The mounting seat 606, which is sleeved outside the limit rod 603, cannot rotate. Rotating the double-acting screw 602 can drive the mounting seat 606 to move upward, ensuring that the scraper 607 on it can fit exactly with the pressure plate 4 and the receiving frame 5. Furthermore, with the cooperation of the self-locking double-acting screw 602 and the worm wheel 604 and the worm gear 605, the position of the mounting seat 606 will not change arbitrarily.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
