Description

Technical Field

[0001] The utility model relates to the technical field of reaction frames, in particular to a self-lifting structural loading reaction frame. Background Art

[0002] In the field of structural engineering, structural loading tests are an important means to evaluate the strength and stability of structures such as buildings, bridges, and mechanical components. Most traditional structural loading reaction frames are of fixed design and cannot flexibly adjust the height of the experimental space according to test requirements; although, in recent years, some reaction frames with adjustable height have emerged, but most rely on external mechanical devices for lifting, with complex operations, high costs, and poor accuracy; and it is often difficult to ensure that the crossbeam remains horizontal when using external mechanical devices for lifting, affecting the accuracy of test results. Content of the Utility Model

[0003] In order to solve the above problems, the utility model proposes a self-lifting structural loading reaction frame to more precisely solve the above problems.

[0004] The utility model is realized through the following technical solutions:

[0005] The utility model proposes a self-lifting structural loading reaction frame, including two frame bodies. Each frame body includes two columns and a top beam arranged at the tops of the two columns. Lifting mechanisms are arranged on both frame bodies. Longitudinal beams are slidably arranged on both frame bodies. The top of the longitudinal beam is connected to the output end of the lifting mechanism. Crossbeams are connected to the bottoms of the two longitudinal beams. The lifting mechanism includes two first hoisting beams arranged at the top of the top beam, upper hanging rings arranged at the bottom of the first hoisting beams and used for hanging lifting parts, and lower hanging parts connected to the other ends of the lifting parts and connected to the crossbeam. Force sensors are arranged on the upper hanging rings.

[0006] Further, the lower hanging part includes a lifting beam, and a lower hanging ring is arranged on the lifting beam.

[0007] Further, suspension rods penetrate through both sides of the crossbeam. The tops of the suspension rods sequentially pass through the longitudinal beam and the second hoisting beam and are threadedly connected to the tops of the second hoisting beams.

[0008] Further, it also includes a plurality of guide wheel groups arranged circumferentially on the top and bottom of the crossbeam and cooperating with the columns.

[0009] Further, the guide wheel group includes a fixing plate connected to the top of the longitudinal beam, and two guide wheels arranged on the fixing plate. The two guide wheels are arranged perpendicular to each other.

[0010] Further, the utility model comprises a plurality of evenly distributed first fixing holes on the column, a plurality of second fixing holes matching with the first fixing holes are formed on both sides of the longitudinal beam and at positions in contact with the column, and screws are connected through internal threads of the first fixing holes and the second fixing holes.

[0011] Furthermore, in the utility model, the lifting member includes an electric hoist.

[0012] Beneficial effects of the utility model:

[0013] The built-in multiple lifting parts can directly lift the beam, eliminating the reliance on external lifting equipment or mechanical devices; this design not only simplifies the operation process and reduces the lifting cost, but also improves the flexibility and adaptability of the test site;

[0014] The force sensor is set up to monitor and measure the force borne by each lifting member in real time. This design enables the operator to quickly find and adjust the force differences between the lifting members, ensuring that all lifting members are balanced during the lifting process, thereby ensuring that the beam can be lifted horizontally and stably; this not only improves the accuracy and reliability of the test, but also avoids potential safety risks caused by the tilt of the beam.

[0023] Embodiment

[0024] Reference Figure 1-6 , a self-liftable structural loading reaction frame, including two frame bodies 1. The frame body 1 includes two columns 11 and a top beam 12 provided at the tops of the two columns 11. Lifting mechanisms 2 are provided on both of the two frame bodies 1. Longitudinal beams 13 are slidably provided on both of the two frame bodies 1. The top of the longitudinal beam 13 is connected to the output end of the lifting mechanism 2. A cross beam 14 is connected to the bottoms of the two longitudinal beams 13. The lifting mechanism 2 includes two first lifting beams 21 provided at the top of the top beam 12, an upper hanging ring 22 provided at the bottom of the first lifting beam 21 and used for hanging the lifting member 24, and a lower suspension member 23 connected to the other end of the lifting member 24 and connected to the cross beam 14. A force sensor 221 is provided on the upper hanging ring 22;

[0025] The setting of the lifting mechanism 2 can realize the height adjustment of the cross beam 14, so that the distance between the bottom of the cross beam 14 and the ground is increased, so that it can be used for placing test articles of different heights, thereby increasing the applicability of the equipment;

[0026] Specifically, the staff lifts a plurality of lifting members 24. The plurality of lifting members 24 can synchronously pull or loosen the circumference of the top of the longitudinal beam 13. The longitudinal beam 13 will synchronously drive the cross beam 14 to move up or down, so as to realize the adjustment of the experimental space, that is, according to the different sizes of the test pieces, adjust the distance between the cross beam 14 and the ground; after the distance between the cross beam 14 and the ground is adjusted, the staff takes out the articles to be tested, places the articles below the cross beam 14, and conducts tests on the articles;

[0027] In this embodiment, optionally, a number of loading test ends are provided on the cross beam 14, and the loading test ends include hydraulic components.

[0028] In this embodiment, the experimental space refers to the distance between the cross beam 14 and the ground;

[0029] In this embodiment, it should be noted that the columns are fixed to the ground by anchor bolts;

[0030] In this embodiment, the lifting member 24 includes an electric hoist 241, and the cross beam 14 is directly lifted by the built-in electric hoist 241, getting rid of the dependence on external lifting equipment or mechanical devices; this design not only simplifies the operation process, reduces the lifting cost, but also improves the flexibility and adaptability of the test site;

[0031] And a force sensor 221 is innovatively installed above the electric hoist 241 for real-time monitoring and measuring the magnitude of the force borne by each electric hoist 241; this design enables the operator to quickly discover and adjust the force difference between the electric hoists 241, ensuring that all electric hoists 241 are evenly stressed during the lifting process, so as to ensure that the cross beam 14 can be lifted horizontally and stably; this not only improves the accuracy and reliability of the test, but also avoids potential safety risks caused by the inclination of the cross beam 14.

[0032] Preferably, referring to Figure 3 , the lower suspension member 23 includes a lifting beam 231, and a lower hanging ring 232 is provided on the lifting beam 231. The setting of the lower hanging ring 232 can be used to connect the output end of the electric hoist 241, so as to realize the connection work between the longitudinal beam 13 and the top beam 12;

[0033] Optionally, referring to Figure 3 , the electric hoist 241 includes an upper hook 242 that cooperates with the upper hanging ring 22, a chain 243 wound around the output end of the electric hoist 241, and a lower hook 244 connected to the end of the chain 243 and cooperating with the lower hanging ring 232;

[0034] Lifting principle of the cross beam 14: When the cross beam 14 needs to be lifted, the output end of the electric hoist 241 will rotate clockwise and wind the chain 243. As the output end of the electric hoist 241 winds the chain 243, the extended length of the chain 243 will decrease, thereby driving the two longitudinal beams 13 to move upward. The two longitudinal beams 13 will synchronously drive the cross beam 14 to move upward, so as to realize the adjustment work of increasing the experimental space; on the contrary, when the cross beam 14 moves downward, the adjustment work of reducing the space is realized;

[0035] In this embodiment, referring to Figure 1, there are four electric hoists 241, and two electric hoists 241 form a group, so as to realize the synchronous pulling work of the two longitudinal beams 13. The setting of the four force sensors 221 can facilitate the staff to observe the pulling force of the electric hoist 241, and facilitate the staff to adjust the pulling force and loosening force of the electric hoist 241 in time, so as to ensure the stability of the cross beam 14 during the rising and falling processes, and avoid potential safety risks caused by the inclination of the cross beam 14;

[0036] In this embodiment, the electric hoist 241 is an existing mature technology. Therefore, the principle and specific structure of the electric hoist 241 will not be described in detail in this application document.

[0037] Preferably, refer to Figure 4 , suspension rods 15 are penetrated through both sides of the cross beam 14. The tops of the suspension rods 15 sequentially pass through the longitudinal beams 13 and the second lifting beam 25, and are threadedly connected to the top of the second lifting beam 25; the setting of the suspension rods 15 can fix the cross beam 14 to the bottoms of the two longitudinal beams 13, and the setting of the second lifting beam 25 can increase the stability of the cross beam 14 after installation, making the connection between the cross beam 14 and the longitudinal beams 13 more stable.

[0038] Preferably, refer to Figure 5 , further including a plurality of guide wheel sets 3 arranged on the circumferences of the top and bottom of the cross beam 14 and cooperating with the columns 11;

[0039] The setting of the guide wheel sets 3 can make the longitudinal beams 13 slide on the preset tracks, thus avoiding the generation of the inclination phenomenon of the longitudinal beams 13;

[0040] Specifically, the guide wheel set 3 includes a fixing plate 31 connected to the top of the longitudinal beam 13, and two guide wheels 32 arranged on the fixing plate 31. The two guide wheels 32 are arranged perpendicular to each other. The two guide wheels 32 are respectively in contact with one side and the front end of the column 11, and clamp the column 11 on one side, which can effectively prevent the longitudinal beam 13 from deviating from the preset track during the lifting process;

[0041] In this embodiment, each longitudinal beam 13 is equipped with 4 guide wheel sets 3, with a total of 16 guide wheel sets 3, so as to ensure that the cross beam 14 can be accurately adjusted up and down along the column 11 along the preset track.

[0042] Preferably, refer to Figure 6, a plurality of uniformly distributed first fixing holes 111 are formed in the column 11. On both sides of the longitudinal beam 13 and at the positions in contact with the column 11, a plurality of second fixing holes 131 are formed which are matched with the first fixing holes 111. Screws are threadedly connected in the first fixing holes 111 and the second fixing holes 131. The cooperation of the screws, the first fixing holes 111 and the second fixing holes 131 can fix the adjusted longitudinal beam 13 on the column 11, thereby ensuring the stability of the longitudinal beam 13 during use.

[0043] It should be noted that the present utility model only protects the mechanical part, and the functions realized by the software control part related thereto are not within the protection scope of the present utility model.

[0044] Of course, the present utility model can also have many other implementation manners. Based on this implementation manner, other implementation manners obtained by those of ordinary skill in the art without any creative work belong to the protection scope of the present utility model.
