Description

Technical Field

[0001] The utility model relates to the technical field of mechanical performance detection of building components, in particular to a detection device for testing the mechanical performance of building keels. Background Art

[0002] Building keels, such as ceiling keels, are structural members used to support ceiling decorative materials such as gypsum boards. They are usually open rectangular frame structures that can provide sufficient strength and rigidity to support the weight of the ceiling. Therefore, the ceiling keels play a load-bearing and supporting role. The mechanical properties of the ceiling keels affect the safety of the quality of the building ceiling. It is necessary to conduct mechanical property tests on the ceiling keels, such as static load tests.

[0003] In the related art, the deflection of the ceiling keel is generally detected by a detection device. For example, the detection device includes a top plate, a plurality of hangers, a ceiling keel and a dial indicator. The plurality of hangers are vertically arranged and the top ends are respectively connected to the top plate, the bottom ends of the plurality of hangers are vertically connected to different parts of the ceiling keel, the dial indicator is installed on the ground, and the test probe of the dial indicator is abutted against the bottom of the ceiling keel. By applying corresponding pressure on the upper part of the ceiling keel and observing the reading of the dial indicator, the deflection (i.e., deformation) of the ceiling keel can be judged to realize a static load test on the ceiling keel.

[0004] However, since the connection position between the top end of the hanger rod and the top plate is usually fixed, the detection device can only detect ceiling keels of a single specification, such as a single test span. When static load tests are performed on ceiling keels with different test spans, multiple hangers are deflected, so that the bottom end of the hanger rod is no longer perpendicular to the ceiling keel, making it difficult to ensure the accuracy of deflection detection of ceiling keels with other test spans.

[0013] Optionally, the support base includes a frame and a plurality of support rods, the frame is a rectangular frame structure, the four corner ends of the frame are respectively connected to the corresponding leg bodies, a plurality of support rods are installed in the frame in an interval arrangement along the second direction, and the deflection detection instrument is used to be installed at different positions of the frame or the support rods.

[0014] Optionally, the first hanging member includes a hanging bolt, a first nut and a second nut, and the hanging member is vertically arranged, the top end of the hanging bolt is passed through the position of the movable beam and connected to the first nut, and the bottom end of the hanging bolt is passed through the position of the building keel and connected to the second nut.

[0031] In view of the problems existing in the above-mentioned related technologies, this embodiment provides a detection device for testing the mechanical properties of building keels.

[0032] like Figure 1As shown, a detection device for testing the mechanical properties of building keels provided by the embodiment of the utility model comprises a support frame 2, a moving beam 1, four hanging parts 3, a deflection detection instrument 4 and a loading plate 5, wherein the support frame 2 comprises a leg assembly 21, two first side beams 22 and two second side beams 23, wherein the two first side beams 22 arranged opposite to each other and the two second side beams 23 arranged opposite to each other form a quadrilateral frame and are installed on the leg assembly 21, and the two ends of the moving beam 1 are respectively connected to the two first side beams 2 arranged at intervals along the first direction. 2, the movable beam 1 is used to move along the second direction on the first side beam 22; wherein two of the hanging members 3 are installed on the movable beam 1 at intervals, and the other two of the hanging members 3 are installed on the second side beam 23 at intervals, and the bottom ends of the four hanging members 3 are used to connect to the building keel 6, and the loading plate 5 is placed on the building keel 6, and the loading plate 5 is used to place weights; the deflection detection instrument 4 is arranged on the support leg assembly 21, and the deflection detection instrument 4 is used to abut against the building keel 6, and the second direction is perpendicular to the first direction.

[0033] Specifically, the first direction can be Figure 1 The middle X-axis direction is parallel to the second direction. Figure 1 The four parts of the building keel 6 can be respectively connected to the bottom ends of the hanging parts 3 at the corresponding positions, and the top ends of two of the hanging parts 3 are connected to the movable beam 1, and the top ends of the other two hanging parts 3 are connected to one of the second side beams 23, so that the building keel 6 can be hung on the supporting frame 2 through the four hanging parts 3.

[0034] The movable beam 1 can move along the second direction on the two first side beams 22 in the supporting frame 2, so that the distance between the two suspension members 3 arranged along the second direction can be adjusted to be suitable for hanging building keels 6 with different test spans, wherein the test span of the building keel 6 refers to the distance between the two hanging ends of the same keel.

[0035] The deflection detection instrument 4 is used to detect the linear displacement (deformation) of the building keel 6 in the vertical direction when the total weight of the weight and the loading plate 5 exerts downward pressure. The loading plate 5 is not only used to stably install the weight on the building keel 6, but also to evenly transmit the pressure of the weight to each detection position of the building keel 6, so as to avoid the building keel 6 being affected by uneven overall force and the accuracy of the static load test.

[0036] The building keel 6 can be a ceiling keel, or other keels that need to be suspended by four suspension members 3. The building keel 6 can be a metal keel, or a non-metal keel with a certain strength.

[0037] This testing device can be used for mechanical property tests of ceiling keels in GB / T 11981-2008, JC / T 2220-2014 and JIS A6517:2010.

[0038] In the present embodiment, before a static load test is required on building keels 6 of different specifications, for example, different test spans, the movable beam 1 can be moved along the second direction on the two first side beams 22 of the support frame 2 according to the test span of the building keel 6. Since the top ends of two of the suspension members 3 are respectively connected to the movable beam 1, and the top ends of the other two suspension members 3 are respectively connected to the second side beams 23, the bottom ends of the four suspension members 3 are respectively connected to the building keel 6. By adjusting the distance between the movable beam 1 and the second side beams 23 corresponding to the movable beam 1 and the parallel thereof, the distance between the two pairs of suspension members 3 arranged along the second direction can be adjusted to ensure that the bottom ends of the four suspension members 3 are perpendicular to the building keel 6. Subsequently, a loading plate 5 can be placed on the upper part of the building keel 6 to realize the installation operation of the building keels 6 of different test spans before the static load test.

[0039] When a static load test is performed on the building keel 6, a weight can be placed on the loading plate 5. Since the deflection detection instrument 4 can be installed on the leg assembly 21, and the detection probe of the deflection detection instrument 4 can abut against the bottom of the building keel 6, the building keel 6 can produce a certain deformation under the total weight of the weight and the loading plate. At this time, the maximum deflection value of the building keel 6 can be detected by the deflection detection instrument 4, which not only realizes the static load test of the building keel 6 with different test spans, but also because the suspension member 3 is perpendicular to the surface of the building keel 6, the accuracy of the deflection detection of the building keel 6 in the static load test can be improved; wherein, the maximum deflection value of the building keel 6 refers to the deflection value detected by the deflection detection instrument after the deformation of the building keel under the total weight of the weight and the loading plate is stabilized.

[0040] Optionally, combined Figure 2 As shown, each of the suspension members 3 arranged on the moving beam 1 is a first suspension member 31, and each of the suspension members 3 arranged on the second side beam 23 is a second suspension member 32. The moving beam 1 is provided with a plurality of first mounting holes 11 which are spaced apart along its own extension direction and are used for the first suspension members 31 to pass through, and the second side beam 23 is provided with a plurality of second mounting holes 231 which are spaced apart along its own extension direction and are used for the second suspension members 32 to pass through.

[0041] Specifically, each of the suspension members 3 disposed on the moving beam 1 and arranged at intervals along the first direction can be defined as a first suspension member 31 , and each of the suspension members 3 disposed on one of the second side beams 23 is a second suspension member 32 .

[0042] A plurality of first mounting holes 11 are distributed on the movable beam 1 at intervals along the first direction, and a plurality of second mounting holes 231 are distributed on the second side beam 23 at intervals along the first direction.

[0043] Since the movable beam 1 can move on the two first side beams 22, the distance between the first suspension member 31 and the second suspension member 32 can be adjusted. For example, the distance between the first suspension member 31 and the second suspension member 32 can be adjusted to 900 mm and 1000 mm (or even more sizes), so it can be suitable for mechanical testing of ceiling keels such as load-bearing keels and covering keels, T-type main keels and T-type secondary keels, such as deflection testing in static load tests.

[0044] In this optional embodiment, since a plurality of first mounting holes 11 arranged at intervals along the first direction are provided on the movable beam 1, the two first suspension members 31 can be selectively inserted into different first mounting holes 11 to adjust the spacing between the two first suspension members 31; similarly, the two second suspension members 32 can be selectively inserted into different second mounting holes 231 to adjust the spacing between the two second suspension members 32. In other words, the spacing between the two first suspension members 31 and the spacing between the two second suspension members 32 can be adjusted so as to be applicable to building keels 6 with different spacings; and, since the movable beam 1 can move on the two first side beams 22 to adjust the spacing between the first suspension member 31 and the second suspension member 32 so as to be applicable to building keels 6 with different test spans, static load tests can be performed on building keels 6 of more different specifications.

[0045] Optionally, combined Figure 2 and Figure 4 As shown, the building keel 6 includes two first keels 61 and multiple second keels 62, the two first keels 61 are arranged at intervals along the first direction, and the multiple second keels 62 are arranged at intervals along the second direction, the two first keels 61 are respectively connected to each of the second keels 62, and the first keel 61 is provided with multiple hanging holes arranged at intervals along its own extension direction, and the bottom ends of a first hanging member 31 and a second hanging member 32 arranged along the second direction are respectively connected to two of the hanging holes on the first keel 61.

[0046] Specifically, the building keel 6 may include two first keels 61 and a plurality of second keels 62, the second keels 62 being vertically connected to the first keels 61, and each second keel 62, for example, is connected to the two first keels 61 at both ends thereof, so as to realize the assembly of the building keel 6. The two first keels 61 are connected to each second keel 62 respectively, which means that when the first keel 61 is a load-bearing keel and the second keel 62 is a covering keel, two different positions between the two ends of each second keel 62 are connected to the corresponding two first keels 61 respectively. When the first keel 61 is a T-shaped main keel and the second keel 62 is a T-shaped secondary keel, the two ends of each second keel 62 are located between the two first keels 61 and are connected to the corresponding two first keels 61 respectively.

[0047] Each first keel 61 is provided with suspension holes arranged at intervals, the bottom ends of the two first suspension members 31 are respectively connected to one end of the corresponding two first keels 61, and the bottom ends of the two second suspension members 32 are respectively connected to the other end of the corresponding two first keels 61.

[0048] The number of the first mounting holes 11 arranged on the movable beam 1 can be multiple, for example, four, and the spacing between two adjacent first mounting holes 11 can be 300 mm. The number of the second mounting holes 231 on the corresponding second side beam 23 can be multiple, for example, four, and the spacing between two adjacent second mounting holes 231 can be 300 mm. The top ends of the two first suspension members 31 arranged at intervals in the first direction are connected to the first mounting holes 11 at different positions, and the top ends of the two second suspension members 32 arranged at intervals in the first direction are connected to the second mounting holes 231 at different positions. The two ends or two different parts between the two ends of each first keel 61 in the building keel 6, such as the ceiling keel, are respectively connected to the corresponding first suspension members 31 and the second suspension members 32. The spacing between the two first suspension members 31 arranged along the first direction and the spacing between the two second suspension members 32 arranged in the first direction can be adjusted to achieve the suspension operation of two first keels 61 with different spacings, such as 300 mm, 600 mm and 900 mm. The distance between two first keels 61 arranged along the first direction is the spacing between the two first keels 61 , and the distance between two hanging ends of the same first keel 61 along the second direction is the test span of the first keel 61 .

[0049] In this optional embodiment, the following building keel 6 is explained by taking the ceiling keel as an example. By adjusting the position of the movable beam 1 on the supporting frame 2 to change the distance between the movable beam 1 and the second side beam 23, it is suitable for the hanging operation of the first keel 61 in the ceiling keels with different test spans; since the top ends of the two first hanging members 31 are respectively connected to the different first mounting holes 11 of the movable beam 1, and the top ends of the two second hanging members 32 are respectively connected to the different second mounting holes 231 of the second side beam 23, the distance between the two first hanging members 31 and the distance between the two second hanging members 32 can be adjusted to be suitable for the hanging operation of ceiling keels with different distances. In other words, compared with the prior art, A set of detection devices can only detect building keels of a single specification, such as a single test span. If it is necessary to detect building keels of other specifications, it is necessary to replace the corresponding detection device. In this embodiment, by changing the position of the movable beam 1 on the support frame 2, as well as the connection position between the top end of the first suspension member 31 and the first mounting hole 11 of the movable beam 1, and the connection position between the top end of the second suspension member 32 and the second mounting hole 231 of the second side beam 23, it is not only suitable for the hanging operation of ceiling keels of different specifications, but also can perform deflection detection on building keels of different specifications, such as different test spans and different spacings, thereby correspondingly improving the test efficiency of building keels of different specifications, such as ceiling keels.

[0050] Optionally, combined Figure 3 As shown, the leg assembly 21 includes a support base 211 and a plurality of leg bodies 212, the four corners of the quadrilateral frame are respectively connected to the corresponding leg bodies 212, the four corner ends of the support base 211 are respectively connected to the corresponding leg bodies 212, the support base 211 is located below the building keel 6, and the deflection detection instrument 4 is installed on the support base 211.

[0051] Specifically, a quadrilateral frame formed by two first side beams 22 and two second side beams 23 is installed on the upper part of the plurality of leg bodies 212 so that the quadrilateral frame has a certain height to meet the hanging conditions for the ceiling keel.

[0052] The support base 211 can be fixed on the leg body 212 in the following manner, for example, the four corners of the support base 211 are respectively connected to the leg body 212 at the corresponding position. The support base 211 can be located below the building keel 6, and the deflection detection instrument 4 can be installed on the support base 211. Since the detection probe of the deflection detection instrument 4 abuts against the bottom of the first keel 61 in the ceiling keel, the deflection detection instrument 4 installed on the support base 211 can improve the accuracy of the deflection detection of the building keel 6, compared with the deflection detection instrument 4 directly installed on the possibly uneven ground.

[0053] The deflection detection instrument 4 may be a dial gauge for detecting the deflection value of the ceiling keel, for example, a digital dial gauge.

[0054] Optionally, combined Figure 2 As shown, when the loading plate 5 is placed on the upper part of the first keel 61 , a plurality of the deflection detection instruments 4 are arranged at intervals along the second direction, and the detection probes of the deflection detection instruments 4 abut against the bottom of the first keel 61 .

[0055] Specifically, the installation position of the loading plate 5 relative to the ceiling keel may be adjusted according to the deflection detection at different positions of the ceiling keel.

[0056] For example, when it is necessary to detect the deflection of the first keel 61, the loading plate 5 can be placed on the upper part of the two first keels 61, and then a weight can be placed on the upper part of the loading plate 5. At this time, the first keel 61 will produce a vertical deformation. Since the detection probe of the deflection detection instrument 4 abuts against the bottom of the first keel 61, the linear displacement of different parts of the first keel 61 can be detected by multiple deflection detection instruments 4 arranged at intervals along the second direction, so as to realize the deflection detection of the first keel 61 in the static load test.

[0057] Optionally, combined Figure 4 As shown, the first keel 61 is a load-bearing keel, and the second keel 62 is a covering keel, and the covering keel is connected to the bottom of the load-bearing keel;

[0058] When the loading plate 5 is placed on the upper part of the second keel 62 , the plurality of deflection detection instruments 4 are arranged at intervals along the first direction, and the detection probes of the deflection detection instruments 4 abut against the bottom of the second keel 62 .

[0059] Specifically, when the first keel 61 is a load-bearing keel and the second keel 62 is a covering keel, the number of the load-bearing keels and the covering keel is two each, the covering keel is located below the load-bearing keel, and the top of the covering keel can be fixed to the bottom of the load-bearing keel by snapping.

[0060] The deflection of the second keel 62, such as the covering keel, can be detected in the following manner. When the deflection of the covering keel needs to be detected, the loading plate 5 can be placed on the upper part of the two covering keels, and then a weight is placed on the upper part of the loading plate 5. At this time, the covering keel will produce vertical deformation. Since multiple deflection detection instruments 4 are installed on the upper part of the support seat 211 at intervals along the first direction, the detection probes of the multiple deflection detection instruments 4 are respectively abutted against different positions of the bottom of the covering keel. The linear displacement of different parts of the second keel 62 can be detected by using the multiple deflection detection instruments 4 arranged at intervals along the first direction to realize the deflection detection of the covering keel in the static load test.

[0061] When the first keel 61 is a load-bearing keel and the second keel 62 is a covering keel, the building keel 6, such as a ceiling keel, includes two load-bearing keels and two covering keels. At this time, the two second keels 62 are installed at intervals along the second direction at the bottom of the two first keels 61; or, when the first keel 61 is a T-shaped main keel and the second keel 62 is a T-shaped secondary keel, the building keel 6, such as a ceiling keel, includes two T-shaped main keels and multiple T-shaped secondary keels. At this time, multiple second keels 62 are arranged at intervals along the second direction, and each second keel 62 is between the two first keels 61, and the two ends of each second keel 62 are connected to the two first keels 61. At this time, the deflection detection instrument 4 can detect the maximum deflection value of the first keel 61. Specifically, the movable beam 1 can be first moved Move along the second direction to change the spacing between the first suspension member 31 and the second suspension member 32 arranged along the second direction. At this time, the spacing between the first suspension member 31 and the second suspension member 32 arranged along the second direction can be adjusted to 900mm; then the connection position between the top end of the first suspension member 31 and the first mounting hole 11 of the movable beam 1, and the connection position between the top end of the second suspension member 32 and the second mounting hole 231 of the second side beam 23 can be adjusted to adjust the spacing between the two first suspension members 31 and the spacing between the two second suspension members 32 to 900mm, and then multiple deflection detection instruments 4 are installed on the upper part of the support seat 211 along the second direction, and the detection probes of the multiple deflection detection instruments 4 are respectively abutted against different positions of the first keel 61 (see Figure 2 As shown), the loading plate 5 is then placed on the upper part of the two first keels 61 to detect the maximum deflection values ​​at different positions of the first keel 61 through a plurality of deflection detection instruments 4 arranged at intervals along the second direction, so as to realize the static load test operation on the first keel 61.

[0062] When detecting the deflection of the T-shaped main keel, for example, the distance between the two first suspension members 31 and the spacing between the two second suspension members 32 can be adjusted to 600mm respectively; the spacing between each first suspension member 31 and each second suspension member 32 arranged along the second direction can be adjusted to 1000mm.

[0063] When the first keel 61 is a T-shaped main keel and the second keel 62 is a T-shaped secondary keel, since the T-shaped secondary keel generally does not bear heavy pressure during the installation of the ceiling, it is not necessary to perform deflection detection on the T-shaped secondary keel.

[0064] Of course, the ceiling keel is not limited to the above-mentioned load-bearing keel and covering keel, T-shaped main keel and T-shaped secondary keel, and can also be keels of other shapes. As long as the first keel and the second keel form a rectangular frame structure after assembly, the deflection test in the mechanical test in the static load test can be carried out by the detection device, and no specific limitation is made here.

[0065] When the first keel 61 is a load-bearing keel and the second keel 62 is a covering keel, the two second keels 62 are installed at intervals along the second direction at the bottom of the two first keels 61. At this time, the deflection detection instrument 4 can detect the deflection of the second keel 62 (for example, the covering keel). Specifically, the movable beam 1 can be moved along the second direction first to change the spacing between the first suspension member 31 and the second suspension member 32 arranged along the second direction. At this time, the spacing between the first suspension member 31 and the second suspension member 32 arranged along the second direction can be adjusted to 900mm; then the connection position between the top end of the first suspension member 31 and the first mounting hole 11 of the movable beam 1, and the connection position between the top end of the second suspension member 32 and the second mounting hole 231 of the second side beam 23 can be adjusted to adjust the spacing between the two first suspension members 31 and the spacing between the two second suspension members 32 to 900mm, and then a plurality of deflection detection instruments 4 are installed on the upper part of the support seat 211 along the first direction, and the detection probes of the plurality of deflection detection instruments 4 are respectively abutted against different positions of the covering keel (combined with Figure 4 As shown), the loading plate 5 is then placed on the upper part of the two load-bearing keels to detect the deflection of the cladding keels at different positions through a plurality of deflection detection instruments 4 arranged at intervals along the first direction, so as to implement the static load test operation on the cladding keels.

[0066] In addition, when the ceiling keel includes a load-bearing keel and a covering keel, the end surface of the load-bearing keel along its own extension direction may be U-shaped, V-shaped or C-shaped, and the end surface of the covering keel along its own extension direction is C-shaped. When the ceiling keel includes a T-shaped main keel and a T-shaped secondary keel, the end surfaces of the T-shaped main keel and the T-shaped secondary keel along their own extension direction are both T-shaped.

[0067] Optionally, combined Figure 3 As shown, the support seat 211 includes a frame 2111 and a plurality of support rods 2112, the frame 2111 is a rectangular frame structure, the four corner ends of the frame 2111 are respectively connected to the corresponding leg bodies 212, and the plurality of support rods 2112 are installed in the frame 2111 in an interval arrangement along the second direction, and the deflection detection instrument 4 is used to be installed at different positions of the frame 2111 or the support rods 2112.

[0068] Specifically, a plurality of support rods 2112 may be arranged in intervals along the second direction in the frame 2111, so that the plurality of support rods 2112 and the frame 2111 are assembled into a support seat 211; the frame 2111 is a quadrilateral structure surrounded by four rod-shaped members, so the frame 2111 may be a rectangular frame structure, and the four corner ends of the frame 2111 are respectively connected to the corresponding leg bodies 212, so that the support seat 211 and the four leg bodies 212 are assembled to form the leg assembly 21. Among them, the support rods 2112 may be connected to the frame 2111 by welding, and the frame 2111 may be connected to the leg bodies 212 by welding.

[0069] In this optional embodiment, since the plurality of support rods 2112 are installed in the frame 2111 in an interval arrangement along the second direction, a plurality of deflection detection instruments 4 can be selectively and stably installed at different positions on the frame 2111 or the support rods 2112 according to the deflection detection of the first keel 61 or the second keel 62 in the ceiling keel, so as to provide a stable installation foundation for the deflection detection instrument 4 through the frame 2111 or the support rods 2112.

[0070] Under the condition that the hanging part is perpendicular to the surface of the first keel of the building keel, before the deflection test of the building keel, such as the first keel 61 and the second keel 62, the quality of the deflection detection instrument 4 can be checked in advance to see whether it is intact, and whether the deflection detection instrument 4 is installed stably on the support seat 211, etc., so as to further improve the accuracy of the deflection detection of the building keel. For example, the support rod 2112 can be a rod-shaped structure made of a metal magnetic material such as an iron material, and the frame 2111 can also be a quadrilateral frame made of a metal magnetic material, and the bottom of the deflection detection instrument 4 has a magnet, so that the deflection detection instrument 4 can be fixedly installed on the support rod 2112 by magnetic adsorption.

[0071] Optionally, combined Figure 5 As shown, the first hanging member 31 includes a hanging bolt 311, a first nut 312 and a second nut 313. The hanging member 3 is vertically arranged. The top end of the hanging bolt 311 is passed through the part of the movable beam 1 and is connected to the first nut 312. The bottom end of the hanging bolt 311 is passed through the part of the building keel 6 and is connected to the second nut 313.

[0072] Specifically, the ceiling keel can be installed in the following manner. For example, the top end of the hanging bolt 311 is passed through the movable beam 1 and then connected to the first nut 312 to achieve the fixation of the hanging bolt 311 and the first nut 312; the bottom end of the hanging bolt 311 is passed through the hanging hole of the first keel 61 in the ceiling keel, and the second hanging member 32 has the same structure as the first hanging member 31. The top end of the second hanging member 32 is passed through the second mounting hole 231 of the second side beam 23, and the bottom end of the second hanging member 32 is passed through the other hanging holes of the first keel 61, so that the ceiling keel can be hung on the support frame 2 through the joint action of the first hanging member 31 and the second hanging member 32.

[0073] Optionally, combined Figure 2 and Figure 4 As shown, the detection device for testing the mechanical properties of building keels also includes two position fixing members 7, which are spaced apart along the first direction, and the position fixing members 7 are used to fix the end of the movable beam 1 and the first side beam 22.

[0074] Specifically, two position fixing members 7 are installed at the ends of the moving beam 1 at intervals along the first direction.

[0075] In this optional embodiment, since the movable beam 1 can move on two relatively parallel first side beams 22 in the supporting frame 2 to perform position adjustment, after the position of the movable beam 1 on the first side beam 22 is adjusted according to the specifications of the ceiling keel, such as the length, the two position fixing members 7 can be used to respectively connect the end of the movable beam 1 and the first side beam 22 to achieve the position locking of the movable beam 1 on the first side beam 22, thereby preventing position displacement during the static load test of the ceiling keel, and correspondingly improving the safety and stability of the static load test of the ceiling keel.

[0076] Optionally, combined Figure 6 As shown, the position fixing member 7 includes a mounting frame 71, an adjusting bolt 72 and a rotating member 73. The mounting frame 71 is arranged at the bottom of the movable beam 1. A threaded hole is provided on the mounting frame 71. The bottom end of the adjusting bolt 72 is connected to the rotating member 73. The top end of the adjusting bolt 72 is passed through the threaded hole and abuts against or is away from the first side beam 22.

[0077] The rotating member 73 is used for manual rotation by the staff, so the rotating member 73 is a handle structure of various shapes, such as a ring structure, a rectangular block, etc. The rotating member 73 of various shapes that can facilitate the staff to operate and rotate is suitable for the present technical solution and is not specifically limited here.

[0078] The locking cam 73 is preferably configured to lock the locking cam 72 with the support frame 71 in a manner that allows the locking cam 72 to move relative to the support frame 71, thereby locking the locking cam 72 in the locking cam 72 and allowing the locking cam 72 to move relative to the support frame 71.

[0079] Although the utility model is disclosed as above, the protection scope of the utility model is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the utility model, and these changes and modifications will fall within the protection scope of the utility model.
