Description

Technical Field

[0001] The utility model relates to the technical field of deflection detection, and particularly relates to a deflection detection device for precast component tests. Background Technique

[0002] Deflection is the linear displacement of the axis of a rod in a direction perpendicular to the axis or the linear displacement of the middle surface of a plate or shell in a direction perpendicular to the middle surface when under force or non-uniform temperature change.

[0003] In the measurement of the mid-span displacement in the precast staircase structural performance test and the measurement of the support settlement displacement in the composite slab structural performance test, different forms of auxiliary frames (brackets or reaction frames) need to be erected to install dial gauges, which are not universal. The on-site erection often has poor effects and wastes time. Generally, the auxiliary frames have large stiffness and cannot deform or shake, so the erection cost is high. And for different test scenarios, the placement angles of the dial gauges are different. Therefore, the traditional auxiliary frames cannot solve the deflection tests in multiple scenarios, resulting in repeated erection of auxiliary frames and waste.

[0004] The existing patent (Publication No.: CN217032950U) discloses a deflection detection device for precast components. This utility model relates to the technical field of deflection detection and discloses a deflection detection device for precast components, including a base, a crossbar assembly, and a vertical rod assembly. The vertical rod assembly is vertically arranged on the base. The crossbar assembly includes a first crossbar, a second crossbar, and a third crossbar. One end of the first crossbar is slidably connected to the vertical rod assembly. The second crossbar is rotatably connected to the other end of the first crossbar. The third crossbar is rotatably connected to the end of the second crossbar. And the second crossbar rotates vertically relative to the first crossbar, and the third crossbar rotates horizontally relative to the second crossbar. A dial gauge is also arranged at the end of the third crossbar. Compared with the prior art, the test designed by this utility model is applicable to tests in different scenarios during the deflection detection of precast components, has strong versatility, stable structure, and saves resources.

[0005] In view of the above problems, the existing patent gives a solution. However, in the above patent, both the unfolding and folding storage of the base need to be manually adjusted by the user, which has the disadvantages of being not intelligent and convenient enough. Moreover, there may be a situation where the unfolding is not complete during manual operation, which will affect the stability during use. At the same time, the height adjustment of the crossbar assembly requires loosening nuts, and this adjustment method is relatively cumbersome and inefficient, which will bring inconvenience to the user during actual operation, especially in the case of frequent adjustment, which will seriously affect the operation efficiency.

[0006] Therefore, a deflection detection device for precast component tests is proposed. Utility Model Content

[0021] 2. In this application, by setting up an adjustment mechanism, when it is necessary to adjust the height of the first crossbar, the motor is started through the controller.

Since the first crossbar is rotatably connected to the top of the adjustment mechanism, and the second crossbar is torsionally connected to the front side of the first crossbar, and the third crossbar is torsionally connected to the front side of the second crossbar, when adjusting the height of the first crossbar, the angles of the other crossbars will be automatically adjusted accordingly to adapt to the height change.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Please refer to Figure 1-8 , the present invention provides a technical solution:

[0033] A precast component test deflection detection device, including a chassis 1, a battery 2 is arranged inside the chassis 1, a support rod 3 is bolted to the top of the chassis 1, a controller 4 is arranged on the front side of the support rod 3, and the controller 4 is electrically connected to the battery 2. A chute 5 is opened inside the support rod 3, and a base mechanism 6 is arranged outside the support rod 3. The base mechanism 6 is electrically connected to the controller 4. An adjustment mechanism 7 is arranged inside the chute 5. The adjustment mechanism 7 includes a motor 701 bolted to the top of the support rod 3. The output end of the motor 701 penetrates through the top of the support rod 3 and extends into the chute 5. The motor 701 is electrically connected to the controller 4. A first cross bar 8 is rotatably connected to the top of the adjustment mechanism 7. A folding support structure 9 is arranged on the front side of the adjustment mechanism 7. The folding support structure 9 is located at the bottom of the first cross bar 8. A second cross bar 10 is torsionally connected to the front side of the first cross bar 8. A third cross bar 11 is torsionally connected to the front side of the second cross bar 10. A U-buckle structure 12 is arranged outside the third cross bar 11. A dial indicator 13 is arranged inside the U-buckle structure 12;

[0034] The base mechanism 6 includes an electric telescopic rod 601 embedded inside the support rod 3. The electric telescopic rod 601 is electrically connected to the controller 4. The telescopic end of the electric telescopic rod 601 is located inside the chute. A sliding sleeve 602 is bolted to the telescopic end of the electric telescopic rod 601. The sliding sleeve 602 is slidably connected to the outside of the support rod 3. Fixed blocks 603 are bolted to the four sides of the outside of the support rod 3. A positioning plate 604 is rotatably connected to the outside of the fixed block 603. A suction cup 605 is arranged at the bottom of the positioning plate 604. Fixed sleeves 606 are bolted to the four sides of the outside of the sliding sleeve 602. A connecting rod 607 is rotatably connected to the inside of the fixed sleeve 606. A rotating sleeve 608 is bolted to the top of the positioning plate 604. The inside of the rotating sleeve 608 is rotatably connected to the connecting rod 607.

[0035] In this embodiment: By setting up the base mechanism 6, the controller 4 controls the telescopic movement of the electric telescopic rod 601. The electric telescopic rod 601 drives the sliding sleeve 602 to slide outside the support rod 3. Through the connection of the fixed sleeve 606, the connecting rod 607 and the rotating sleeve 608, the sliding sleeve 602 drives the positioning plate 604 to rotate around the fixed block 603, realizing the unfolding and folding storage of the positioning plate 604. When the positioning plate 604 is unfolded, the suction cup 605 at the bottom adsorbs the ground, enhancing the stability of the device. This automatically controlled base mechanism 6 improves the intelligent convenience of the device, avoids the problem of incomplete unfolding that may occur in manual operation, and ensures the stability during use. By setting up the adjustment mechanism 7, the controller 4 starts the motor 701. The output end of the motor 701 drives the adjustment mechanism 7 to move in the chute 5, thereby adjusting the height of the first crossbar 8. The torsional connection between the first crossbar 8, the second crossbar 10, and the third crossbar 11 enables the angles of the other crossbars to automatically adapt to changes when adjusting the height, eliminating the need for the manual adjustment method of loosening nuts, greatly improving the adjustment efficiency, and facilitating the operation of the user during frequent adjustments.

[0036] Specifically, as Figure 5 shown, a lead screw 702 is bolted to the output end of the motor 701, and the lead screw 702 is located inside the chute 5.

[0037] Specifically, as Figure 5 shown, a first support block 703 is threadedly connected to the top surface of the lead screw 702. The first support block 703 is slidably connected inside the chute 5, and the front side of the first support block 703 is rotatably connected to the rear side of the first crossbar 8.

[0038] Specifically, as Figure 5 shown, a second support block 704 is threadedly connected to the top surface of the lead screw 702. The second support block 704 is slidably connected inside the chute 5. The second support block 704 is located at the bottom of the first support block 703, and the front side of the second support block 704 is bolted to the rear side of the folding support structure 9.

[0039] In this embodiment: Through the lead screw 702 bolted to the output end of the motor 701, and the first support block 703 and the second support block 704 threadedly connected to the surface of the lead screw 702, when the motor 701 is started, the lead screw 702 rotates, causing the first support block 703 and the second support block 704 to slide in the chute 5, thereby driving the first crossbar 8 and the folding support structure 9 to move, realizing the adjustment of the height of the first crossbar 8. This structure is simple and reliable, and can accurately control the height position of the first crossbar 8.

[0040] Specifically, as Figure 6 shown, the folding support structure 9 includes an adapter sleeve 901 bolted to the front side of the second support block. An electric push rod 902 is rotatably connected inside the adapter sleeve 901, and the electric push rod 902 is electrically connected to the controller 4.

[0041] Specifically, as Figure 6 shown, a connecting sleeve 903 is bolted to the bottom of the first crossbar 8, and the telescopic end of the electric push rod 902 is rotatably connected to the inside of the connecting sleeve 903.

[0042] In this embodiment: Through the cooperation of the connecting sleeve 901, the electric push rod 902 and the connecting sleeve 903 in the folding support structure 9, the controller 4 controls the telescoping of the electric push rod 902. The telescopic end of the electric push rod 902 rotates within the connecting sleeve 903, thereby pushing or pulling the first crossbar 8 to adjust the angle of the first crossbar 8. In this way, the angle of the first crossbar 8 can be flexibly adjusted according to actual needs to meet different detection requirements.

[0043] Specifically, as Figure 8 shown, the U-buckle structure 12 includes a first buckle sleeve 1201 sleeved on the surface of the third crossbar 11, and the inside of the first buckle sleeve 1201 is in contact with the outside of the third crossbar 11.

[0044] Specifically, as Figure 8 shown, a second buckle sleeve 1202 is bolted to the right side of the first buckle sleeve 1201, and the inside of the second buckle sleeve 1202 is inserted with a dial indicator 13.

[0045] In this embodiment: Through the first buckle sleeve 1201 and the second buckle sleeve 1202 in the U-buckle structure, the first buckle sleeve 1201 is sleeved on the surface of the third crossbar 11 and in contact with it, and the second buckle sleeve 1202 is inserted with the dial indicator 13, which can stably fix the dial indicator 13 on the third crossbar 11. At the same time, it is convenient for the installation and disassembly of the dial indicator 13, facilitating use and maintenance.

[0046] Specifically, as Figure 4 shown, a charging port 14 is embedded in the front side of the chassis 1, and the charging port 14 is electrically connected to the battery 2.

[0047] Specifically, as Figure 4 shown, a protective pad 15 is bonded to the bottom of the chassis 1, and the protective pad 15 is made of rubber material.

[0048] In this embodiment: Through the charging port 14 embedded in the front side of the chassis 1, it is convenient to charge the battery 2 to ensure the normal use of the device. The rubber protective pad 15 bonded to the bottom of the chassis 1 can play a role in buffering and anti-slip, protecting the chassis 1 from wear, and at the same time increasing the stability of the device during use.

[0049] Working principle: During the use of the precast component test deflection detection device, the controller 4 controls the telescoping of the electric telescopic rod 601. When the electric telescopic rod 601 extends, its telescopic end drives the sliding sleeve 602 to slide downward on the outer side of the support rod 3. Through the linkage of the fixed sleeve 606, the connecting rod 607 and the rotating sleeve 608, the positioning plate 604 rotates and unfolds around the fixed block 603. The suction cup 605 at the bottom of the positioning plate 604 adsorbs the ground to ensure the stable placement of the device. At the same time, the controller 4 starts the motor 701, and the lead screw 702 at the output end of the motor 701 rotates, driving the first support block 703 and the second support block 704 connected by threads to slide in the chute 5, thereby adjusting the height of the first crossbar 8. The torsion connection between the first crossbar 8, the second crossbar 10, and the third crossbar 11 will automatically adapt to the height change. In addition, the electric push rod 902 in the folding support structure 9 extends and retracts under the control of the controller 4. Through the connection of the connecting sleeve 901 and the connecting sleeve 903, the angle of the first crossbar 8 is adjusted. The first buckle sleeve 1201 and the second buckle sleeve 1202 in the U-buckle structure stably fix the dial indicator 13 on the third crossbar 11. The charging port 14 on the front side of the chassis 1 is used to charge the battery 2, and the protective pad 15 at the bottom plays a role in buffering and anti-slip. The overall cooperation realizes the automatic deployment and storage of the device, as well as the height adjustment and the stable installation of the dial indicator 13, and improves the intelligence, stability, and operation convenience of the detection device.

[0050] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention.
