Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them.

They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be construed as limiting the present invention. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0040] The embodiment of the present invention provides a large-scale holding pole static load detection device, which can perform static load detection on different positions of the holding pole, thereby improving the detection efficiency and accuracy.

[0041] The following combination Figure 1-Figure 5 The technical solution provided by the present invention is described in more detail.

[0042] like Figure 1-Figure 5 As shown, the large-scale holding pole static load detection device provided by the present invention includes a base body, a clamping assembly, a first adjustment mechanism, a pressure assembly, a second adjustment mechanism and a movable plate 5, wherein: two groups of clamping assemblies are respectively fixed at opposite ends of the base body, and are used to clamp and fix the holding pole; the pressure assembly and the movable plate 5 are respectively located on the upper and lower sides of the holding pole to be detected, the first adjustment mechanism is transmission-connected with the movable plate 5, and is used to drive the movable plate 5 to move linearly in the horizontal direction; the second adjustment mechanism is transmission-connected with the pressure assembly, and is used to drive the pressure assembly to move linearly in the horizontal direction; a pressure sensor 6 is provided on the movable plate 5, and a strain gauge sensor 20 is fixed on the holding pole, and the pressure assembly includes a pressure block 10, which is movably arranged in the vertical direction. When the pressure block 10 is pressed down on the part to be detected on the holding pole, the pressure sensor 6 is used to detect the pressure magnitude, and the strain gauge sensor 20 is used to detect whether the holding pole is deformed.

[0043] The pressure sensor 6 and strain gauge sensor 20 are currently mature technologies and will not be described in detail here. The strain gauge sensor 20 indirectly measures physical quantities such as force, pressure, and torque by detecting surface strain (deformation). Its core principle is based on the resistive strain effect of materials.

[0044] The large-scale static load detection device provided by the present invention features a clamping assembly that stably clamps and secures the pole. A first adjustment mechanism drives the horizontal movement of the movable plate 5, while a second adjustment mechanism drives the horizontal movement of the pressure-applying assembly. This allows for static load detection at various positions on the pole, facilitating easy operation and improving detection efficiency. When the pressure block 10 presses down on the pole, the pressure sensor 6 detects the pressure. By attaching the strain gauge sensor 20 to the detection point on the pole body 3, the strain gauge sensor 20 continuously monitors any deformation of the pole body 3 during subsequent testing. This allows for precise detection of the static load value of the pole body 3, improving detection efficiency and accuracy.

[0045] When the strain gauge sensor 20 is attached to the detection point of the boom body 3, during the subsequent detection process, the strain gauge sensor 20 can be used to know at any time whether the boom body 3 is deformed, so that the static load value of the boom body 3 can be accurately detected, thereby improving the efficiency and accuracy of the detection.

[0046] As an alternative embodiment, see Figure 1 and Figure 2 As shown, the seat body includes a base 1 and an inverted U-shaped plate 8, wherein: the vertical sections of the inverted U-shaped plate 8 are respectively fixed on the opposite sides of the base 1, the pressure component is movably arranged on the horizontal section of the inverted U-shaped plate 8, and the movable plate 5 is movably arranged on the base 1.

[0047] The above structure facilitates the arrangement of the movable plate 5 and the pressure assembly on the lower side and the upper side of the boom body 3 , thereby cooperating with the detection of the static load value of the boom body 3 .

[0048] As an alternative embodiment, see Figure 1 and Figure 2 、 Figure 3 As shown, the pressure assembly also includes a cylinder 9, the second adjusting mechanism is transmission-connected to the cylinder 9, the first adjusting mechanism and the second adjusting mechanism cooperate to drive the cylinder 9 to move synchronously with the movable plate 5 in the horizontal direction, the cylinder 9 is vertically arranged, and the pressure block 10 is fixed to the telescopic end of the cylinder 9.

[0049] When the cylinder 9 extends, it can drive the pressure block 10 to descend until the pressure block 10 continuously presses down the boom body 3, so that the pressure sensor 6 can detect the vertical pressure and the strain gauge sensor 20 can detect whether the boom body 3 is deformed.

[0050] As an alternative embodiment, see Figure 1-Figure 3As shown, the first adjustment mechanism includes a driving device (such as a motor 18), a first screw rod 15, two first sliders 17, and a limit rod 16, wherein: slide grooves are provided on opposite sides of the base 1, the first screw rod 15 is rotatably connected to one of the slide grooves, and the limit rod 16 is fixed in the other slide groove. The driving device is drivably connected to the first screw rod 15 and is used to drive the first screw rod 15 to rotate, one of the first sliders 17 is threadedly connected to the first screw rod 15 and is slidably connected to the corresponding slide groove, the other first slider 17 is sleeved on the limit rod 16 and is slidably connected to the corresponding slide groove, and the movable plate 5 is fixedly connected to the two first sliders 17.

[0051] The above-mentioned first adjustment mechanism, the driving device can be a motor 18, the motor 18 drives the first screw rod 15 to rotate. Since the movable plate 5 is fixedly connected to the two first sliders 17 at the same time, the limit rod 16 plays a limiting role, so that the movable plate 5 can move along the length direction of the first screw rod 15, thereby adjusting the horizontal position of the movable plate 5 and the pressure sensor 6.

[0052] As an alternative embodiment, see Figure 1-Figure 3 As shown, the second adjustment mechanism includes a second screw rod 19 and a second slider 21, wherein: the second screw rod 19 is rotatably connected to the top of the vertical section of the inverted U-shaped plate 8, the second slider 21 is threadedly connected to the second screw rod 19, and the second slider 21 is slidingly connected to the horizontal section of the inverted U-shaped plate 8; the first screw rod 15 and the second screw rod 19 are connected through a sprocket 22 chain 23 structure transmission connection.

[0053] In order to prevent the second slider 21 from rotating, Figure 3 As shown, the upper surface of the second sliding block 21 is in contact with the lower surface of the inverted U-shaped plate 8 , that is, the second sliding block 21 is slidably connected to the horizontal section of the inverted U-shaped plate 8 .

[0054] Because the second slider 21 is in contact with the lower surface of the inverted U-shaped plate 8 , it can play a role of limiting, thereby preventing the second slider 21 from rotating along with the second screw rod 19 .

[0055] Specifically, sprockets 22 are fixed to the ends of the first screw rod 15 and the second screw rod 19, and the two sprockets 22 are driven by a chain 23. Of course, the first screw rod 15 and the second screw rod 19 can also rotate synchronously by belt transmission.

[0056] The motor 18 is started to rotate the first screw rod 15, and then the second screw rod 19 is rotated by the transmission of the two chains 23 and the sprocket 22. Here, the first screw rod 15 and the second screw rod 19 are screw rods of the same specifications, so the first slider 17 and the second slider 21 can move synchronously, that is, the pressure block 10 and the pressure sensor 6 can always be on the same vertical line, so as to facilitate the detection of other different positions of the large holding pole.

[0057] For fixing the large mast body 3, as an optional embodiment, see Figure 1 and Figure 2 As shown, the clamping assembly includes a fixed block 2, a fixed rod 4 and a locking mechanism, wherein: the fixed block 2 is fixed on the base body, and the fixed block 2 is a U-shaped block, thereby forming a placement groove 202; slots 201 are opened on the two vertical sections of the fixed block 2, and the notches of the slots 201 are set upward. The fixed rod 4 is an inverted U-shaped rod body structure, and the two vertical sections of the fixed rod 4 are respectively inserted into the slots 201. The locking mechanism locks the fixed rod 4 on the fixed block 2, and the fixed block 2 and the fixed rod 4 clamp and fix the holding rod located in the placement groove 202.

[0058] The above structure can limit the four sides of the pole body 3, clamping and fixing the four sides of the pole body 3 to prevent the pole body 3 from shifting during testing. The two sets of clamping components fix the two ends of the pole body 3, further improving the fixing effect.

[0059] As an alternative embodiment, see Figure 1 、 Figure 2 and Figure 4 、 Figure 5 As shown, the locking mechanism includes a fixing plate 13, an insert 14 and a screw 11, wherein: the screw 11 passes through the fixing plate 13 and is threadedly connected to the fixing plate 13, and the two inserts 14 are fixed to the fixing plate 13; a through hole 203 is provided on the vertical section of the fixing block 2, and the through hole 203 is connected to the slot 201, and an internal threaded hole 204 is provided on the horizontal section of the fixing block 2, and a fixing hole 41 is opened on the vertical section of the fixing rod 4, and the screw 11 is threadedly connected to the internal threaded hole 204, and the insert 14 passes through the through hole 203 and is inserted into the fixing hole 41, thereby locking the fixing rod 4.

[0060] Place the large holding pole body 3 into the two placement slots 202, then insert the two fixing rods 4 into the corresponding slots 201 respectively and move downward to press the large holding pole body 3, then rotate the two screws 11 to make the two screws 11 rotate, and then move the two fixing plates 13 toward the fixing block 2, so that each insertion block 14 can be inserted into the corresponding fixing hole 41, so that the two fixing rods 4 can be fixed, that is, the large holding pole body 3 is fixed.

[0061] As an alternative embodiment, see Figure 4 As shown, a knob 12 is fixed to the end of the screw rod 11 facing away from the fixing rod 4, and holding the knob 12 facilitates turning the screw rod 11; more than two fixing holes 41 are provided on the same vertical section of the fixing rod 4, and the fixing holes 41 are arranged at intervals in the vertical direction.

[0062] By adjusting the position of the fixing plate 13 in the vertical direction, the inserting block 14 can be inserted into different fixing holes 41, thereby facilitating the fixing of pole bodies of different sizes.

[0063] As an optional embodiment, the pressure block 10 and the pressure sensor 6 are located on the same vertical line; in order to prevent the strain gauge sensor 20 from being crushed, as shown in FIG. Figure 2 、 Figure 3 As shown, a pressure plate 7 is fixed on the pressure sensor 6 , and a groove 701 is provided on the upper surface of the pressure plate 7 , and the strain gauge sensor 20 can be placed in the groove 701 .

[0064] The upper surface of the pressing plate 7 is provided with a groove 701, which matches the strain gauge sensor 20. The groove 701 can facilitate the placement of the strain gauge sensor 20, thereby preventing the strain gauge sensor 20 from being crushed.

[0065] In order to remind staff immediately, see Figure 1-Figure 3 As shown, as an optional embodiment, an alarm light 24 is fixedly connected to one side of one clamping assembly, and the strain gauge sensor 20 and the alarm light 24 are both electrically connected to a controller.

[0066] The strain gauge sensor 20 is electrically connected to the alarm light 24 , so when the strain gauge sensor 20 detects that the large holding pole body 3 is deformed, the alarm light 24 can immediately alert the staff.

[0067] In order to display the value of the pressure sensor 6 in real time, Figure 1 、 Figure 3 As shown, a display is fixedly connected to one side of the base 1, and the display matches the pressure sensor 6. The display can display the value of the pressure sensor 6 in real time.

[0068] In summary, when using the large-scale holding pole static load detection device, first place the large-scale holding pole body 3 into the two placement slots 202, then insert the two fixing rods 4 into the corresponding slots 201 respectively and move downward to press the large-scale holding pole body 3, then rotate the two knobs 12 to rotate the two screws 11, and then move the two fixing plates 13 so that each insert block 14 can be inserted into the corresponding fixing hole 41, so that the two fixing rods 4 can be fixed, that is, the large-scale holding pole body 3 is fixed. Then, the strain gauge sensor 20 is attached to the position to be detected, and then the motor 18 is started to rotate the first screw rod 15. Then, the second screw rod 19 can be rotated by the transmission of the two chains 23 and the sprocket 22. Then, the first slider 17 and the second slider 21 can be moved synchronously to the specified position. Then, the cylinder 9 is started, and a static load is applied to the large boom body 3 through the pressure block 10. At this time, the applied pressure can be detected by the pressure sensor 6. When the large boom body 3 is deformed, the strain gauge sensor 20 sends an electrical signal to the alarm light 24 and makes it sound to alert the staff. Then, the cylinder 9 is immediately turned off, and the value of the pressure sensor 6 at this time is recorded, and then displayed on the display, so as to know the limit value of the static load at this position of the large boom body 3.
