DETAILED DESCRIPTION

[0018] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments so that those skilled in the art can implement the invention with reference to the description.

[0019] It should be understood that the terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0020] like Figure 1 As shown, the present invention provides a pipe pile verticality detection device, comprising: a strip board 1 with two connecting ends 120, which is used to surround the outer side of the pipe pile 7, and the two connecting ends 120 are connected by a fixing portion 2; a positioning portion arranged on the inner side of the strip board 1, which is used to contact the outer side of the pipe pile 7 and position the strip board 1, so that the axis of the strip board 1 in a ring shape coincides with the axis of the pipe pile 7; a verticality detector 3, which is movably arranged on the outer side of the strip board 1.

[0021] The strip plate 1 is surrounded on the outside of the pipe pile 7, and then the position of the strip plate 1 is positioned by the positioning part so that the axis of the strip plate 1 formed in a ring can coincide with the axis of the pipe pile 7, and then the two connecting ends 120 are fixed by the fixing part 2 to stably fix the strip plate 1 on the outside of the pipe pile 7; In this way, the position of the verticality detector 3 located on the strip board 1 can also be quickly located, so that when the verticality detector 3 performs verticality detection, the verticality of the axis of the pipe pile 7 can be accurately measured; and when the pipe pile 7 is constructed, the surrounding position of the strip board 1 does not affect the hammering of the pipe pile 7, and there is no need to accurately locate the position of the verticality detector 3 after each hammering, which is convenient to use.

[0022] like Figure 2 As shown, in one embodiment, a plurality of mounting grooves 110 are arranged on the inner side of the strip board 1, and the plurality of mounting grooves 110 are arranged in at least two layers, the upper and lower layers, and the mounting grooves 110 of each layer are evenly spaced along the length direction of the strip board 1; The positioning portion includes: a plurality of contact bodies 4 for contacting the outer side of the pipe pile 7 , and the contact bodies 4 are arranged in the installation groove 110 .

[0023] The contact body 4 is divided into two layers, an upper layer and an lower layer. When the strip plate 1 is arranged around the outside of the pipe pile 7, if the axis of the ring-shaped strip plate 1 deviates from the axis of the pipe pile 7, the contact pressure between the contact bodies 4 and the pipe pile 7 corresponding to the upper and lower layers will deviate. Therefore, the contact body 4 divided into two layers can detect the contact pressure of the pipe pile 7 to position the strip plate 1, thereby ensuring the accuracy of the position of the verticality detector 3 and improving the accuracy of the verticality detection.

[0024] Furthermore, a pressure sensor is provided on the contact body 4 in a direction perpendicular to the side of the strip board 1 , and the pressure sensor is used to detect the contact pressure between the contact body 4 and the outer side of the pipe pile 7 .

[0025] When the strip 1 is arranged around the outside of the pipe pile 7, multiple pressure sensors of the positioning part detect whether the axis of the strip 1 forming a ring coincides with the axis of the pipe pile 7; if not, the strip 1 is adjusted, and if so, the average value of multiple pressure sensors is obtained as the locking force detection value, and when the locking force detection value reaches the set locking force, the two connecting ends 120 are connected through the fixing part 2.

[0026] A plurality of pressure sensors can be remotely connected to the control terminal. When detecting whether the axis of the circular strip 1 coincides with the axis of the pipe pile 7, the control terminal can obtain corresponding detection information to prompt the operator.

[0027] Among them, the locking force is set to: the static friction force generated between the positioning part and the pipe pile 7 is greater than the locking force corresponding to the up and down vibration force generated on the strip board 1 by the maximum hammer force on the pipe pile 7; this is because during the construction of the pipe pile 7, the strip board 1 will be subjected to the vibration in the up and down directions, and the vibration will cause the position of the strip board 1 fixed on the outside of the pipe pile 7 to shift, which will affect the detection accuracy of the verticality detector 3. Therefore, during the installation of the strip board 1, the locking force of the strip board 1 can be detected by the positioning part to prevent the strip board 1 from moving due to the vibration; of course, even if the position of the strip board 1 is offset, the multiple pressure sensors of the positioning part can be used to detect whether the axis of the strip board 1 formed in a ring coincides with the axis of the pipe pile 7, so as to adjust the position of the strip board 1.

[0028] The multiple pressure sensors of the positioning part detect whether the axis of the strip plate 1 and the axis of the pipe pile 7 are coincident, including: Two pressure sensors located at corresponding positions of the upper layer and the lower layer are grouped together, and the pressure difference between the two pressure sensors in each group is obtained; Determine whether the pressure difference is within the set range. If the pressure difference of at least one group of pressure sensors is not within the set range, the axis of the ring-shaped strips 1 deviates from the axis of the pipe pile 7. If the pressure difference of each group of pressure sensors is within the set range, the axis of the ring-shaped strips 1 coincides with the axis of the pipe pile 7.

[0029] Through the above-mentioned detection method, the installation position of the strip board 1 can be located and adjusted in time so that the axis of the ring-shaped strip board 1 coincides with the axis of the pipe pile 7, thereby ensuring the accuracy of the verticality detection of the axis of the pipe pile 7 by the verticality detector 3, so as to improve the construction quality of the pipe pile 7 and thus ensure the structural bearing capacity of the pile-board bridge.

[0030] like Figure 4 and Figure 5 As shown, in one embodiment, the contact body 4 includes: a contact block 410 and a support body 420, and a space area for installing the support body 420 is provided in the contact block 410; the inner side of the contact block 410 is used to contact the outer side of the pipe pile 7, and mounting blocks 5 are respectively provided at both ends of the outer side of the contact block 410, and the mounting blocks 5 are connected in the mounting groove 110; the pressure sensor is arranged on the inner side of the contact block 410 or on the outer side of the contact block 410; under the action of external force, the inner and outer sides of the contact block 410 can produce relative movement in the axial direction of the pipe pile 7.

[0031] The contact block 410 is elastic as a whole, the mounting block 5 is made of hard material, a first permanent magnet is arranged on the outer side or bottom side of the mounting block 5, and a second permanent magnet that is mutually attracted to the first permanent magnet is arranged at a corresponding position of the mounting groove 110; like Figure 7 As shown, the installation groove 110 located on the upper layer of the strip board 1 passes through the upper side of the strip board 1, and the installation groove 110 located on the lower layer passes through the lower side of the strip board 1. When installing, the support body 420 is first installed in the space area of ​​the contact block 410, and then the contact body 4 is inserted from the opening of the installation groove 110. The contact body 4 and the installation groove 110 are fixed by the mutual adsorption of the first permanent magnet and the second permanent magnet. Of course, the two can also be fixed by a snap-on method.

[0032] The support body 420 is detachable, so that it is easy to replace the support body 420 to change the support elasticity of the contact body 4.

[0033] like Figure 6As shown, the contact block 410 includes: an inner plate 411 for contacting the pipe pile 7, an outer plate 412 arranged in the mounting groove 110, an upper plate 413 for connecting the inner plate 411 and the upper ends of the outer plate 412, and a lower plate 414 for connecting the inner plate 411 and the lower ends of the outer plate 412, and a space area is formed among the inner plate 411, the outer plate 412, the upper plate 413 and the lower plate 414; the mounting blocks 5 are arranged at both ends of the outer plate 412, and the two ends of the space area are respectively provided with limit blocks 415 for limiting the movement of the support body 420.

[0034] The side of the inner plate 411 in contact with the pipe pile 7 may be provided with a hard contact plate, or a contact plate for increasing the contact friction force; The support body 420 is inserted from one side of the space area, and the limit block 415 with elastic deformation ability on this side is squeezed and inserted into the interior of the space area, and then is restricted in the space area by the limit blocks 415 on both sides of the space area; When the strip board 1 is fixed, the inner plate 411 is squeezed by the pipe pile 7, so that the support body 420 and the outer plate 412 are squeezed. At this time, the pressure sensor can detect the pressure change, thereby realizing the positioning and locking of the strip board 1; After the strip board 1 is arranged around the pipe pile 7, when the pipe pile 7 is constructed, the strip board 1 is subjected to the up and down vibration force. Since the inner plate 411 is in close contact with the pipe pile 7, the vibration will be first transmitted to the inner plate 411, and the upper plate 413 and the lower plate 414 with elastic deformation ability will deform under the action of vibration, which will cause the inner plate 411 and the outer plate 414 to have a relative movement tendency. Under the elastic recovery action of the upper plate 413 and the lower plate 414, the vibration transmitted to the outer plate 414 can be reduced, thereby preventing the strip board 1 connected to the outer plate 414 from being offset in position. The multiple contact bodies 4 can reduce the influence of vibration on the strip board 1, thereby ensuring the accuracy of the position of the strip board 1.

[0035] like Figure 7 As shown, in one embodiment, two connecting ends 120 are respectively extended from both ends of the strip 1 along its length direction, and a receiving opening 130 is provided above one connecting end 120 and below the other connecting end 120. When the strip 1 is formed into a ring, one connecting end 120 can be located at the receiving opening 130 on one side of the other connecting end 120.

[0036] When the strip board 1 is formed into a ring, the two connecting end portions 120 are staggered up and down, and then the two connecting end portions 120 are fixed by the fixing portion 2; the length of the connecting end portion 120 is equal to the length of the accommodating opening 130, and the length of the connecting end portion 120 can be set according to the circumference of the pipe pile 7, that is, the minimum circumference of the strip board 1 formed into a ring should be smaller than the circumference of the pipe pile 7, and the maximum circumference of the strip board 1 formed into a ring should be larger than the circumference of the pipe pile 7.

[0037] Furthermore, if Figure 3 As shown, a contact body 4 is also provided on the inner side of the connecting end 120 for providing support for the installation and fixation of the strip board 1 .

[0038] like Figure 2 , Figure 7 as well as Fig. 9 As shown, in one embodiment, the fixing portion 2 includes: a fixing plate 210, a first sliding groove 121 for sliding the fixing plate 210 is provided on the connecting end portion 120; a plurality of first locking holes 122 are arranged on the outer side of the connecting end portion 120 along its length direction, and the fixing plate 210 is provided with second locking holes 211 corresponding to the first locking holes 122 of the two connecting end portions 120 respectively, and the first locking holes 122 and the second locking holes 211 are connected by a locking member 220.

[0039] The upper and lower ends of the fixing plate 210 are provided with first sliding blocks corresponding to the first sliding groove 121, so that the fixing plate 210 can slide in the first sliding groove 121, so that the second locking holes 211 arranged above and below can be respectively aligned with at least one of the multiple first locking holes 122 on the two connecting ends 120, and then installed and fixed by the locking member 220, so as to fix the strip plate 1 on the outside of the pipe pile 1.

[0040] Further, the first locking hole 122 is a threaded hole, the second locking hole 211 is a through hole, and the locking member 220 is a bolt; Alternatively, the first locking hole 122 and the second locking hole 211 are both snap-fit ​​holes, and the locking member 220 is a snap-fit ​​member that matches the snap-fit ​​holes.

[0041] like Figure 2 and Fig. 9 As shown, in one embodiment, the verticality detector 3 is movably arranged on the strip board 1 through the support plate 6; the upper and lower sides of the strip board 1 are respectively provided with second slide grooves 140, and the support plate 6 is slidably arranged in the second slide grooves 140, and the outer side of the support plate 6 is used to install the verticality detector 3.

[0042] The upper and lower ends of the support plate 6 are provided with second sliding blocks corresponding to the second slide groove 140, so that the support plate 6 can slide in the second slide groove 140, and the verticality detector 3 is installed on the support plate 6 by bolt connection; the verticality detector 3 can select any instrument that can be installed on the support plate 6 and perform verticality detection on the pipe pile 7.

[0043] In one embodiment, the annular strip plate 1 is divided into at least four detection areas; when the verticality of the pipe pile 7 is detected, the verticality detector 3 detects the verticality of the pipe pile 7 in the four detection areas respectively.

[0044] In order to further improve the accuracy of detection, the circular strip board 1 can be divided into four detection areas, such as Fig.10 The center line shown is divided into four detection areas A, B, C, and D. When performing detection, the verticality detector 3 can be placed in the four detection areas for detection, and then the average value is taken as the verticality detection result; in addition, there can be one or more detection points in the four detection areas.

[0045] A method for detecting the verticality of a pipe pile, using the device for detecting the verticality of a pipe pile according to the present invention, comprises: When the strip board 1 is arranged around the outside of the pipe pile 7, multiple pressure sensors of the positioning part detect whether the axis of the strip board 1 in a ring shape coincides with the axis of the pipe pile 7; If not, adjust the strip 1 until the axis of the strip 1 forming a ring coincides with the axis of the pipe pile 7; if yes, obtain the average value of multiple pressure sensors as the locking force detection value, and when the locking force detection value reaches the set locking force, connect the two connecting ends 120 through the fixing part 2; The annular strip plate 1 is divided into at least four detection areas, and the verticality of the pipe pile 7 is detected in the four detection areas respectively by using the verticality detector 3.

[0046] The locking force is set to be the locking force corresponding to the static friction force generated between the positioning part and the pipe pile 7 being greater than the up and down vibration force generated on the strip board 1 by the maximum hammering force on the pipe pile 7. This is because during the construction of the pipe pile 7, the strip board 1 will be subjected to the up and down vibration, and the vibration will cause the position of the strip board 1 fixed on the outside of the pipe pile 7 to be offset, which will affect the detection accuracy of the verticality detector 3. Therefore, during the installation of the strip board 1, the locking force of the strip board 1 can be detected by the positioning part to prevent the strip board 1 from moving due to the vibration. Of course, even if the position of the strip board 1 is offset, the multiple pressure sensors of the positioning part can be used to detect whether the axis of the strip board 1 formed in a ring coincides with the axis of the pipe pile 7, so as to adjust the position of the strip board 1. like Fig.10 The center line shown is divided into four detection areas A, B, C, and D. When performing detection, the verticality detector 3 can be placed in the four detection areas for detection, and then the average value is taken as the verticality detection result.

[0047] Through the above method, the position of the verticality detector 3 located on the strip board 1 can also be quickly located, so that when the verticality detector 3 is detecting, the verticality of the axis of the pipe pile 7 can be accurately measured; and when the pipe pile 7 is constructed, the surrounding position of the strip board 1 does not affect the hammering of the pipe pile 7, and there is no need to accurately locate the position of the verticality detector 3 after each hammering, which is convenient to use; and the vibration of the strip board 1 generated during the construction of the pipe pile 7 will not cause the position of the strip board 1 to be offset, thereby reducing the adjustment of the position of the strip board 1.

[0048] Furthermore, the plurality of pressure sensors of the positioning part detect whether the axis of the ring-shaped strip plate 1 coincides with the axis of the pipe pile 7, including: Two pressure sensors located at corresponding positions of the upper layer and the lower layer are grouped together, and the pressure difference between the two pressure sensors in each group is obtained; Determine whether the pressure difference is within the set range. If the pressure difference of at least one group of pressure sensors is not within the set range, the axis of the ring-shaped strips 1 deviates from the axis of the pipe pile 7. If the pressure difference of each group of pressure sensors is within the set range, the axis of the ring-shaped strips 1 coincides with the axis of the pipe pile 7.

[0049] Through the above-mentioned detection method, the installation position of the strip board 1 can be located and adjusted in time so that the axis of the ring-shaped strip board 1 coincides with the axis of the pipe pile 7, thereby ensuring the accuracy of the verticality detection of the axis of the pipe pile 7 by the verticality detector 3, so as to improve the construction quality of the pipe pile 7 and thus ensure the structural bearing capacity of the pile-board bridge.
