[0022] An embodiment of the present invention provides a large pole static load detection device, which can perform static load detection on different positions of the pole, improving the efficiency and accuracy of the detection.

[0023] The following Figures 1 - 5 elaborates on the technical solution provided by the present invention in more detail.

[0024] As Figures 1 - 5 shown, the large pole static load detection device provided by the present invention includes a base body, a clamping assembly, a first adjustment mechanism, a pressing assembly, a second adjustment mechanism, and a moving plate 5, wherein: two sets of clamping assemblies are respectively fixed at opposite ends of the base body for clamping and fixing the pole; the pressing assembly and the moving plate 5 are respectively located on the upper and lower sides of the pole to be detected, the first adjustment mechanism is in transmission connection with the moving plate 5 for driving the moving plate 5 to move linearly in the horizontal direction; the second adjustment mechanism is in transmission connection with the pressing assembly for driving the pressing assembly to move linearly in the horizontal direction; a pressure sensor 6 is arranged on the moving plate 5, a strain gauge sensor 20 is fixed on the pole, the pressing assembly includes a pressing block 10, the pressing block 10 is movably arranged in the vertical direction, when the pressing block 10 presses on the part of the pole to be detected, the pressure sensor 6 is used to detect the magnitude of the pressure, and the strain gauge sensor 20 is used to detect whether the pole deforms.

[0025] Among them, the pressure sensor 6 and the strain gauge sensor 20 are existing mature technologies and will not be elaborated here. The strain gauge sensor 20 is a sensor that indirectly measures physical quantities such as force, pressure, and torque by detecting the surface strain (deformation) of an object, and its core principle is based on the resistance strain effect of materials.

[0026] 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.

[0027] 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.

[0028] 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.

[0029] 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 .

[0030] 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.

[0031] 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.

[0032] As an alternative embodiment, see Figures 1 - 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.

[0033] 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.

[0034] As an alternative embodiment, see Figures 1 - 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.

[0035] 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 .

[0036] 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 .

[0037] 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.

[0038] 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.

[0039] For the fixation of the large gin pole body 3, as an alternative implementation, refer to Figure 1 and Figure 2 As shown, the clamping assembly includes a fixing block 2, a fixing rod 4 and a locking mechanism, where: the fixing block 2 is fixed on the seat body, and the fixing block 2 is a U-shaped block, thus forming a placement groove 202; slots 201 are formed on the two vertical sections of the fixing block 2, and the openings of the slots 201 are arranged upward. The fixing rod 4 is an inverted U-shaped rod structure, and the two vertical sections of the fixing rod 4 are respectively inserted into the slots 201. The locking mechanism locks the fixing rod 4 to the fixing block 2, and the fixing block 2 and the fixing rod 4 clamp and fix the gin pole located in the placement groove 202.

[0040] The above structure can limit the four sides of the gin pole body 3, clamp and fix the four sides of the gin pole body 3, and prevent the gin pole body 3 from shifting during testing. Two groups of clamping assemblies fix the two ends of the gin pole body 3, further improving the fixing effect.

[0041] As an alternative implementation, refer to Figure 1 、 Figure 2 and Figure 4 、 Figure 5 As shown, the locking mechanism includes a fixing plate 13, an insertion block 14 and a screw rod 11, where: the screw rod 11 passes through the fixing plate 13 and is threadedly connected to the fixing plate 13, and two insertion blocks 14 are fixed on the fixing plate 13; a through hole 203 is provided on the vertical section of the fixing block 2, the through hole 203 is communicated with the slot 201, an internal threaded hole 204 is provided on the horizontal section of the fixing block 2, a fixing hole 41 is formed on the vertical section of the fixing rod 4, the screw rod 11 is threadedly connected to the internal threaded hole 204, and the insertion block 14 passes through the through hole 203 and is inserted into the fixing hole 41, thereby locking the fixing rod 4.

[0042] Place the large gin pole body 3 into the interiors of the two placement grooves 202, then insert the two fixing rods 4 into the corresponding slots 201 respectively and move them downward to press the large gin pole body 3 tightly. Then rotate the two screw rods 11 to make the two screw rods 11 rotate. Then the two fixing plates 13 move towards the fixing block 2, so that each insertion block 14 can be inserted into the corresponding fixing hole 41, enabling the two fixing rods 4 to be fixed, that is, fixing the large gin pole body 3.

[0043] As an alternative implementation, refer to Figure 4 As shown, a knob 12 is fixed to the end of the screw rod 11 away from the fixing rod 4, and holding the knob 12 facilitates screwing the screw rod 11; two or more 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.

[0044] By adjusting the position of the fixing plate 13 in the vertical direction, the insertion block 14 can be inserted into different fixing holes 41, thus facilitating the fixation of gin pole bodies of different sizes.

[0045] As an optional implementation, the briquette 10 and the pressure sensor 6 are on the same vertical line; to prevent the strain gauge sensor 20 from being damaged, as Figure 2 、 Figure 3 shown, a pressing plate 7 is fixed on the pressure sensor 6, and a groove 701 is formed on the upper surface of the pressing plate 7, and the strain gauge sensor 20 can be placed in the groove 701.

[0046] The upper surface of the pressing plate 7 is provided with a groove 701, and the groove 701 matches the strain gauge sensor 20. The groove 701 can be used to facilitate the placement of the strain gauge sensor 20, thereby preventing the strain gauge sensor 20 from being damaged.

[0047] To remind the staff in the first time, see Figures 1 - 3 shown, as an optional implementation, an alarm lamp 24 is fixedly connected to one side of one of the clamping assemblies, and the strain gauge sensor 20 and the alarm lamp 24 are both electrically connected to a controller.

[0048] The strain gauge sensor 20 is electrically connected to the alarm lamp 24, so when the strain gauge sensor 20 detects the deformation of the large boom body 3, the staff can be reminded by the alarm lamp 24 in the first time.

[0049] To display the value of the pressure sensor 6 in real time, as Figure 1 、 Figure 3 shown, a display is fixedly connected to one side of the base 1, and the display matches the pressure sensor 6. The value of the pressure sensor 6 can be displayed in real time by using the display.

[0050] In summary, when using the large gin pole static load detection device, first place the large gin pole body 3 into the interior of the two placement grooves 202. Subsequently, insert the two fixing rods 4 into the corresponding insertion slots 201 respectively and move them downward to press tightly against the large gin pole body 3. Then rotate the two knobs 12 to make the two screw rods 11 rotate. Subsequently, the two fixing plates 13 move, so that each insertion block 14 can be inserted into the corresponding fixing hole 41, enabling the two fixing rods 4 to be fixed, that is, fixing the large gin pole body 3. Then attach the strain gauge sensor 20 to the position to be detected. Subsequently, start the motor 18 to make the first lead screw 15 rotate. Then, through the transmission of the two chains 23 and the sprockets 22, the second lead screw 19 can be made to rotate. Subsequently, the first slider 17 and the second slider 21 can move synchronously to the specified position. Then start the cylinder 9, and apply a static load to the large gin pole body 3 through the pressing block 10. At this time, the pressure applied can be detected by the pressure sensor 6. When the large gin pole body 3 deforms, the strain gauge sensor 20 sends an electrical signal to the alarm lamp 24 and makes it emit a sound to remind the staff. Then immediately turn off the cylinder 9 and record the value of the pressure sensor 6 at this time. Subsequently, it is displayed through the display, so as to know the limit value of the static load at this position of the large gin pole body 3.
