[0002] With the continuous development of urban construction, pile foundation, as an important infrastructure, is particularly important for quality inspection. Pile foundation inspection is an important means to ensure the quality of pile foundation construction. The commonly used inspection method requires that multiple probes be lowered to different depths in the pile foundation pit for data collection. To ensure the accuracy of the inspection results, the distance between the lowering and lifting of each probe is required to be consistent. However, since the winding and releasing of the cable depends more on the experience and cooperation of the staff, it often leads to low winding accuracy and large data collection errors. In addition, long-term cable winding will cause fatigue to the staff, making it difficult to maintain stable synchronous winding of multiple cables and probes, thus affecting the reliability of the inspection results.

[0003] Therefore, based on the above-stated viewpoint, there is still room for improvement in the existing technical means for synchronous cable winding. Summary of the invention

DETAILED DESCRIPTION

[0036] The following is combined with Figure 1 To Attachment Fig.11 Embodiments of the present invention are described in detail.

[0037] The embodiment of the present application discloses a pile foundation test winding detection device and method, which explains that the winding device is mainly used in the process of winding and releasing cables during pile foundation detection, and technically realizes the effect of automatically winding and releasing multiple cables on multiple reels; in particular, during use, the clamping and unclamping of the cables by the cable clamp can effectively prevent the position of the probe in the pile foundation pit from changing; further, the winding device also synchronously winds and releases multiple cables on multiple reels through the cooperation of the cable clamp and the cable puller, thereby ensuring that the lowering and lifting distances of multiple probes corresponding to the cables in the pile foundation pit are the same.

[0038] Example 1: Reference Figure 1 As shown, a pile foundation test winding detection device includes a wire drum rack 1, a plurality of wire drums 10 and a meter 11. The wire drum rack 1 is used to connect and limit the wire drum 10, and the meter 11 is used to measure the length of the cable. It is usually installed on the ground through a tripod. A winding assembly 2 for limiting and tightening the cable is connected between the wire drum rack 1 and the meter 11. It is used to synchronously drive all cables and probes to move up or continue to be lowered in the pile foundation pit after the staff puts a plurality of cables and probes into the pile foundation pit.

[0039] It should be noted that in the process of conventionally using probes to detect pile foundations, workers are usually required to first place several probes and cables into the pile foundation pit in sequence, and then adjust the relative positions of all cables and probes to keep all probes in the pile foundation pit at the same level.

[0040] Reference Figures 1 to 3As shown, the winding assembly 2 is used for limiting and tightening the cable; specifically, the winding assembly 2 includes: The wire clamp 20 is arranged between the wire drum rack 1 and the meter 11 and connected to the wire drum rack 1, and is used to limit and clamp a plurality of cables sliding thereon. The cables on the plurality of wire drums 10 pass through the wire clamp 20 and the meter 11 side by side in sequence and then penetrate into the pile foundation pit.

[0041] The cable reel 21 is connected to the cable reel frame 1 and the cable reel 10 and is used to provide the driving force required for winding the cable.

[0042] The limiting frame 22 is slidably connected to the wire drum frame 1 and abuts against the wire drum 10 through an elastic member to limit the wire drum 10 to be connected to the wire drum frame 1.

[0043] Reference Figure 2 and Figure 3 As shown, it is used for limiting and clamping several cables sliding thereon; specifically, the wire clamp 20 includes a supporting connecting plate 200 arranged on one side of the wire drum rack 1 close to the meter 11, and the supporting connecting plate 200 is connected to a limiting guide rail 201, and a limiting clamping plate 202 is inserted in the limiting guide rail 201 for limiting position, and a sliding groove is formed on the limiting clamping plate 202 corresponding to the meter 11, and a plurality of clamping plates 203 are passed through the sliding groove, and a driven screw 204 is commonly passed through all the clamping plates 203, and two adjacent clamping plates 203 in the sliding groove are in contact with each other to clamp one of the cables passing through. When in use, the cable slides through between two adjacent clamping plates 203 in the sliding groove, then slides through the meter 11 and sinks into the pile foundation pit, and then the driven screw 204 is driven to rotate forward to drive the clamping plate 203 on the driven screw 204 to shift, thereby driving the clamping plate 203 to clamp the cable passing therethrough to prevent the probe and cable from falling back after the position is adjusted.

[0044] Further, refer to Figure 2 and Figure 3As shown, in order to achieve the effect of clamping the multiple cables passing through the sliding groove one by one, one of the multiple adjacent clamping plates 203 located in the sliding groove is limitedly connected to the limit clamping plate 202, and the other clamping plate 203 is threaded through by the driven screw 204 and driven to slide in the sliding groove. The multiple adjacent clamping plates 203 in the sliding groove are connected to the limit clamping plate 202 at intervals, that is, the multiple spaced clamping plates 203 are driven by the driven screw 204 to slide. Therefore, when in use, by driving the driven screw 204 to rotate forward, the multiple locking plates 203 driven by the driven screw 204 to slide are allowed to slide in the direction close to the limiting guide rail 201, that is, the driven screw 204 is driven so that all the locking plates 203 driven by it are allowed to be close to another adjacent locking plate 203 limited on the limiting clamping plate 202, thereby achieving the effect of clamping and limiting multiple cables one by one.

[0045] Reference Figure 3 and Figure 4 As shown, the cable drum rack 1 and the supporting connecting plate 200 are commonly connected with a driving shaft 23, and the driving shaft 23 and the driven screw 204 are both sleeved with a passive bevel gear 24, and the two passive bevel gears 24 are meshed with each other. The end of the driving shaft 23 away from the driven screw 204 is connected with a driving motor, and the driving motor is connected to the cable drum rack 1 through a motor frame; the driving shaft 23 and the connected passive bevel gear 24 are driven to rotate by the driving motor, and the rotation of the passive bevel gear 24 drives another passive bevel gear 24 meshed with it and the driven screw 204 to rotate, thereby realizing the synchronous rotation between the driving shaft 23 and the driven screw 204, and then realizing the effect of controlling the clamping plate 203 to clamp and release the cable.

[0046] Reference Figure 5 and Figure 6 As shown, the cable reel 21 is used to provide the driving force required for winding the cable; specifically, the cable reel 21 includes a plurality of mounting seats 210 connected to the cable drum rack 1, and a driving rotary disc 211 correspondingly connected to the cable drum 10 is installed on the mounting seat 210, which is used to drive the cable drum 10 to rotate to reel the cable, and a driving shaft 212 passing through the mounting seat 210 and the cable drum rack 1 is coaxially connected to the side of the driving rotary disc 211 away from the cable drum 10. When in use, by driving the driving shaft 212 and the driving rotary disc 211 to rotate, the driving rotary disc 211 rotates to drive the connected cable drum 10 to rotate, so as to achieve the effect of winding or releasing the cable on the cable drum 10.

[0047] Furthermore, since most conventional existing cable drums 10 used for pile foundation testing have a handle eccentrically connected to one side to facilitate workers to reel in and release the cable, a limit sleeve for limiting the connected handle is correspondingly eccentrically provided on the driving turntable 211. The limit sleeve, handle and cable drum 10 are driven to rotate by rotating the driving turntable 211 to achieve the effect of reeling or releasing the cable on the cable drum 10.

[0048] Reference Figure 6 and Figure 7 As shown, in the conventional pile foundation detection process, it is often necessary to use a probe or multiple probes to cooperate with each other for detection, and accordingly, it is also necessary to use one or more wire drums 10 to connect the probes. Based on this, the wire drum rack 1 is also correspondingly provided with a multi-section combined structure, wherein any one of the wire drum racks 1 is arranged in an "L"-shaped bending shape, and is arranged side by side in sequence for connecting and limiting the wire drums 10. A limiting frame 22, a driving shaft 212, a driving turntable 211 and a limiting sleeve are provided on the multiple wire drum racks 1, and are connected one by one with the multiple wire drums 10. A transmission shaft 213 is passed through the horizontal section of the wire drum rack 1, and the transmission shaft 213 and the driving shaft 212 are connected together by a synchronous belt transmission. When in use, one of the driving shafts 212 is driven to rotate, and the driving shaft 213 is driven to rotate synchronously through the synchronous belt between the transmission shaft 213 and the driving shaft 212. The rotation of the transmission shaft 213 drives the remaining driving shafts 212 to rotate synchronously through the synchronous drive, thereby driving all the driving shafts 212, the driving turntable 211, the limiting sleeve and the wire drum 10 to rotate synchronously, thereby achieving the effect of synchronously winding the cables on multiple wire drums 10.

[0049] Reference Figure 6 and Figure 7 As shown, in order to facilitate the combination of multiple wire drum racks 1 to drive multiple wire drums 10 to be synchronously wound, the transmission shaft 213 is also set to a multi-section type corresponding to the multiple wire drum racks 1, and the transmission shaft 213 includes a corresponding connecting sleeve 2130 that is rotated and penetrated on the wire drum rack 1, and a spline protrusion 2131 is provided at one end of the connecting sleeve 2130 away from the vertical section of the wire drum rack 1. The spline protrusion 2131 and the connecting sleeve 2130 on another wire drum rack 1 are inserted together by spline matching to combine multiple wire drum racks 1.

[0050] Reference Figure 8 As shown, in order to facilitate the guiding and limiting of the cables on the cable drum 10, the cable drum rack 1 is also limitedly connected with a driven slide plate 25, and a guide slot 250 is formed on the driven slide plate 25 for the cable to slide. When in use, the cable is placed in the guide slot 250 on the driven slide plate 25 in advance, and the cable slides through the guide slot 250, the sliding slot and the meter 11 in sequence.

[0051] Further, refer to Figure 8 As shown, as the cable drum 10 rotates to wind or release the cable, the cable will slide back and forth in a certain range in the horizontal direction along the cable drum 10, so a reciprocating screw 251 connected to the limit frame 22 is penetrated on the driven slide plate 25, and two interlaced threads are opened on the outer side of the reciprocating screw 251, and the reciprocating screw 251 is connected to the driving shaft 212 through a synchronous belt transmission. The reciprocating screw 251 is driven to rotate synchronously by the rotation of the driving shaft 212, and the driven slide plate 25 slides back and forth along the reciprocating screw 251 through the two threads connected to the reciprocating screw 251, so that the cable on the cable drum 10 always keeps axially passing through the guide slot 250 on the driven slide plate 25.

[0052] Reference Figure 8 As shown, in order to limit and guide the sliding of the driven slide 25, the lower end of the driven slide 25 is connected to a limit guide block 252 inserted on the bobbin frame 1, and a limit slide groove is formed on the bobbin frame 1 for the limit guide block 252 to slide. When the reciprocating screw 251 rotates, the limit guide block 252 is limited by the limit slide groove on the bobbin frame 1, and the limit guide block 252 limits the driven slide 25, so that when the driven slide 25 is driven by the reciprocating screw 251, it always slides axially back and forth along the reciprocating screw 251.

[0053] Example 2: Reference Figures 9 to 11 As shown, on the basis of Example 1, when a plurality of cables and probes are used to cooperate with each other to perform pile foundation detection, since it is necessary to keep all the probes sunk in the pile foundation pit at the same horizontal height, and a plurality of cables used to connect the probes need to maintain the relative positions of the probes after passing through the same meter 11, the plurality of cables will connect the probes at different angles after passing through the same meter 11. Therefore, in actual use, when the plurality of cables keep the connected probes at the same horizontal height after passing through the same meter 11, the lengths of the cables themselves used to connect the probes are different.

[0054] Based on this, in order to keep the lowering and lifting distances of multiple probes corresponding to the cables in the pile foundation pit the same, a wire puller 26 corresponding to the wire clamp 20 is also connected to the limit guide rail 201, and the wire puller 26 includes a sliding clamp 260 slidably inserted on the limit guide rail 201, and the sliding clamp 260 and the limit clamp 202 are correspondingly provided with a sliding groove, a clamping plate 203 and an adjusting screw 261, wherein the sliding clamp The multiple engaging plates 203 on the plate 260 also correspond to the multiple engaging plates 203 on the limit engaging plate 202 and are driven to slide at intervals by the adjusting screw 261. The threads on the adjusting screw 261 and the driven screw 204 are oppositely arranged. The adjusting screw 261 and the active shaft 23 are also connected through a bevel gear transmission. Specifically, the active shaft 23 and the adjusting screw 261 are both provided with a driven bevel gear 262, and the two driven bevel gears 262 are meshed with each other.

[0055] Furthermore, the active rotating shaft 23 includes a spline sleeve 230 rotatably connected to the limiting guide rail 201, a spline rotating shaft 231 is slidably inserted into the spline sleeve 230, and a driving sleeve 232 connected to the driving motor is sleeved on the side of the spline rotating shaft 231 away from the spline sleeve 230. The spline sleeve 230 and the spline rotating shaft 231 as well as the spline rotating shaft 231 and the driving sleeve 232 are all spline-matched, and one of the passive bevel gears 24 and the driven bevel gear 262 are respectively connected to the spline sleeve 230 and the spline rotating shaft 231.

[0056] A driving screw 263 is provided on the sliding card plate 260 and the limiting guide rail 201. The driving screw 263 is threadedly connected to the sliding card plate 260 and is rotationally connected to the limiting guide rail 201. The driving screw 263 is provided with two threads with opposite rotation directions. The driving screw 263 and the driving sleeve 232 are connected through a belt drive.

[0057] In the initial state, when the probe needs to be lifted synchronously, the sliding clamping plate 260 on the limiting guide rail 201 is installed close to the limiting clamping plate 202 .

[0058] When in use, the driving sleeve 232 is driven to rotate, and the rotation of the driving sleeve 232 drives the spline shaft 231 and the spline sleeve 230 to rotate, and the driven screw 204 and the adjusting screw 261 are synchronously driven to rotate through the meshing between the passive bevel gear 24 and the driven bevel gear 262. Due to the opposite threads on the driven screw 204 and the adjusting screw 261, the several clamping plates 203 on the limit clamping plate 202 and the sliding clamping plate 260 that are threaded with the driven screw 204 and the adjusting screw 261 slide in the direction away from the limit guide rail 201 and towards the limit guide rail 201 respectively, thereby achieving the effect of releasing the cable on the limit clamping plate 202 and clamping the cable on the sliding clamping plate 260 at the same time.

[0059] At the same time, the rotation of the driving sleeve 232 also drives the driving screw 263 to rotate synchronously through the belt transmission. After the driving screw 263 rotates, the sliding clamping plate 260 slides along the driving screw 263 and the limiting guide rail 201 toward the direction close to the wire drum rack 1 through the thread. At this time, due to the clamping of several cables by several clamping plates 203 on the sliding clamping plate 260, the sliding clamping plate 260 also synchronously pulls several cables to slide toward the direction close to the wire drum rack 1 when sliding, thereby achieving the effect of synchronously driving all probes located in the pile foundation pit to be lifted up to the same distance.

[0060] On the contrary, when the driving sleeve 232 is driven to rotate in the opposite direction, the driving screw 263, the driven screw 204 and the adjusting screw 261 will all rotate in the opposite direction. At this time, the several clamping plates 203 on the limit clamping plate 202 will clamp the cable again, while the several clamping plates 203 on the sliding clamping plate 260 will release the clamping of the cable, and this reciprocating process is realized to achieve the effect of driving all the probes located in the pile foundation pit to continuously lift up the same distance.

[0061] It should be noted that, in the above state, the sliding card plate 260 always slides along one of the threads when driven to slide by the driven screw 263, and during the sliding process, the sliding card plate 260 also synchronously drives the spline shaft 231, the adjusting screw 261 and the two driven bevel gears 262 to slide synchronously through the connecting plate.

[0062] Based on the above, when the sliding clamping plate 260 on the limiting guide rail 201 is installed close to the wire drum rack 1, the sliding clamping plate 260 will be driven to slide by another opposite thread on the driving screw 263.

[0063] At this time, the driving sleeve 232 is driven to rotate forward, and the driving screw 263 rotates to drive the sliding clamping plate 260 to slide in the direction away from the wire drum rack 1. At the same time, the driving sleeve 232 rotates forward, driving the driving screw 263, the driven screw 204 and the adjusting screw 261 to rotate forward, and the several clamping plates 203 on the sliding clamping plate 260 clamp the cable, and the several clamping plates 203 on the limit clamping plate 202 release the clamping of the cable, and with the sliding of the sliding clamping plate 260 and the several clamping plates 203 connected thereto, the cable is driven to slide in the direction away from the wire drum rack 1, so as to achieve the synchronous release of all probes and cables, so that the lowering distances of several probes in the pile foundation pit are the same.

[0064] Furthermore, refer to Figures 9 to 11As shown, since the adjusting screw 261 and the driven screw 204 are driven to rotate synchronously by the spline sleeve 230 and the spline shaft 231, a vacuum period will inevitably occur in the process of the limit clamping plate 202 and the sliding clamping plate 260 relatively alternatingly clamping and releasing the cable, that is, in the process of the adjusting screw 261 and the driven screw 204 rotating synchronously to drive the connected several clamping plates 203 to clamp or release the cable, there will be a situation where all the clamping plates 203 on the limit clamping plate 202 and the sliding clamping plate 260 fail to clamp the cable. At this time, the probe may fall back due to the influence of its own weight, thereby affecting the accuracy of the detection data during the detection process.

[0065] Therefore, the passive bevel gear 24 connected to the spline sleeve 230 and the driven bevel gear 262 connected to the spline shaft 231 are both incomplete bevel gears, and the toothless segments on the passive bevel gear 24 and the driven bevel gear 262 are set at relative deflection angles to achieve the effect of driving the driven screw 204 and the adjusting screw 261 to rotate synchronously in an alternating manner.

[0066] In addition, the present invention also provides a pile foundation test coiling detection method, comprising the following steps: S1: Place the wire drum rack 1 on the ground and connect several wire drums 10 to the wire drum rack 1 through the limit frame 22, then connect the meter 11 through a tripod and install it away from the wire drum rack 1, pull the cables on the several wire drums 10 through the wire clamp 20 and the meter 11 side by side and sink them into the pile foundation pit, adjust the cable length to keep multiple probes at the same level after sinking.

[0067] S2: The cable reels 21 are used to drive all the cable drums 10 to rotate synchronously, so as to achieve the effect of synchronously winding or releasing the cables by the multiple cable drums 10 .

[0068] S3: Through the cooperation of the cable clamp 20 and the cable puller 26, several cables are clamped and limited in an interlaced manner after passing through the limit clamp 202 and the sliding clamp 260, and at the same time, the sliding clamp 260 is driven to clamp the cables to drive the cables to slide and shift, thereby driving all the probes connected to the corresponding cables to be synchronously lifted or moved down.

[0069] S4: While the cable is stretched and displaced or released and displaced by the cable puller 26 and the cable gripper 20, all the cable drums 10 are driven to rotate accordingly by the cable reel 21, and the cables on the cable drums 10 are synchronously wound or released.

[0070] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered as exemplary and non-restrictive in all respects.

[0071] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
