Description

Technical Field

[0001] This utility model relates to the field of pile foundation testing technology, and in particular to an automatic wire take-up device for pile foundation testing. Background Technology

[0002] Pile foundations are one of the main foundation forms used in the construction of high-rise buildings, factories, bridges, ports and docks. Their quality directly affects the safety of the entire building. Current technologies for pile foundation testing often utilize sound waves, which have a comprehensive detection range, accurate and reliable results, and are not limited by pile length, site conditions, etc., and are therefore widely used. However, in traditional pile foundation testing, when using the sonic transmission method, it is necessary to manually set up the probe and cable, and lower the device tens of meters underground to test the pile foundation. Currently, the cable needs to be wound up and down, usually manually wound by operators. This method is time-consuming, labor-intensive, and inefficient. The cable is also prone to tangling and wear. Furthermore, when winding the cable in the field, the cable is prone to adhering to mud, and the device and cable themselves become dirty during winding, which cannot be cleaned in time.

[0003] Therefore, based on customer feedback regarding the shortcomings of the existing device structure, the inventors made further improvements to overcome the aforementioned problems. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an automatic cable reeling device for pile foundation testing that requires no manual operation, saves time and effort, enables simultaneous reeling and unloading of multiple cables, effectively avoids cable tangling, and can clean the cables.

[0005] The purpose of this utility model is achieved through the following technical solution: an automatic wire take-up device for pile foundation testing, comprising a housing, a mounting frame, and a wire reel;

[0006] The housing is equipped with a mounting frame, and a movable block is provided on the mounting frame. The movable block moves left and right on the mounting frame with the cooperation of an electromagnetic ring structure and a spring. A rotatable spool is connected to the upper surface of the movable block and a cable is wound on the spool. Toothed rings are coaxially connected to the left and right sides of the spool. The toothed rings are driven to rotate by a drive component located next to the mounting frame.

[0007] When winding up the cable, the drive component first drives the toothed ring to rotate, which in turn causes the reel connected to the toothed ring to rotate and wind up the cable. At this time, the electromagnetic ring structure is energized to make the moving block move left and right on the mounting frame. The reel rotates while moving horizontally to wind up the cable, effectively preventing the cable from getting tangled during winding up.

[0008] As a preferred technical solution of this application, the mounting frame includes a bracket and a central rod; the bracket is perpendicular to the inner bottom surface of the outer shell and a central rod is horizontally mounted on the upper part of the bracket, and a fixed magnetic ring is respectively passed through the left and right ends of the central rod, while the left and right sides of the movable block sleeved on the outside of the central rod are respectively connected to movable magnetic rings.

[0009] As a preferred technical solution of this application, the fixed magnetic ring is divided into a first ring and a second ring, while the movable magnetic ring is divided into a third ring and a fourth ring, with the first ring and the third ring arranged opposite to each other, and the second ring and the fourth ring arranged opposite to each other;

[0010] When the fixed magnetic ring and the movable magnetic ring are energized respectively, the first ring and the third ring are energized and attract each other, at which time the movable block moves to the left; when the second ring and the fourth ring are energized and attract each other, the movable block moves to the right.

[0011] As a preferred technical solution of this application, a buffer spring is provided between the first ring and the third ring, and a buffer spring is also provided between the second ring and the fourth ring. The buffer spring is sleeved outside the central rod, and the moving block is reset when the power is off by the buffer spring.

[0012] As a preferred technical solution of this application, multiple mounting brackets are arranged in parallel in the housing, and each mounting bracket is independently equipped with a reel for winding up the line.

[0013] As a preferred technical solution of this application, the driving component includes a long column and a support; multiple serrations are formed around the outer side of the long column, the support is set on the side of the mounting frame, and one end of the long column is connected to the motor, so that the long column is rotatably mounted on the upper part of the support. The toothed ring of the spool meshes with the serrations of the long column, and the driving motor makes the long column rotate, which drives the toothed ring to rotate, thereby driving the spool to rotate.

[0014] As a preferred technical solution of this application, the outer shell is an irregular frame structure, and the lower part of the outer shell is provided with multiple cable through holes on the frame surface of multiple mounting brackets arranged in parallel, with each cable through hole corresponding to one of the multiple mounting brackets.

[0015] As a preferred technical solution of this application, a cleaning tube is coaxially provided on the outer side of the cable through hole, the cleaning tube has a central opening, and the inner wall of the tube is provided with bristles around the circumference. When the cable is retracted into the outer shell via the cable reel, the bristles brush away the dust and dirt on the cable.

[0016] This utility model has the following advantages:

[0017] (1) No manual operation is required to achieve simultaneous multi-line take-up and release;

[0018] Currently, testing requires manual setup and configuration of probes and cables, with operators manually winding up the cables. This process is time-consuming, labor-intensive, and inefficient. Furthermore, existing cable winding devices are complex and cannot simultaneously wind up or unwind multiple cables, nor can they support multiple channels. This solution, however, uses a motor to drive a toothed column that engages with a toothed ring, causing the cable reel to rotate and wind up the cable. This eliminates manual operation and improves efficiency. Additionally, multiple cable reel mechanisms are arranged side-by-side, with the same long column driving the reel to wind up the cable, enabling simultaneous winding and unwinding of multiple cables.

[0019] (2) Effectively prevents cable tangling during cable winding and cleans the cable;

[0020] This solution uses a movable block that moves left and right on the mounting frame. The movement of the movable block is achieved through the cooperation of an electromagnetic ring and a spring, which prevents the cable from getting tangled during winding. At the same time, a cleaning pipe is installed on the outside of the device. The inside of the pipe has dense bristles, which clean the outside of the retrieved cable to remove dirt and other adhering materials. Attached Figure Description

[0029] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0030] It should be noted that the orientation or positional relationship indicated by terms such as "left" and "right" is based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the product of this invention is usually placed in during use, or the orientation or positional relationship that is commonly understood by those skilled in the art. Such terms are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0032] Therefore, based on the above issues, please refer to Figure 1 This utility model proposes an automatic wire take-up device for pile foundation testing to solve the problem.

[0033] See Figures 1 to 7 The present implementation scheme proposes an automatic wire take-up device for pile foundation testing, which includes a wire reel 1, a mounting frame 2, and an electromagnetic ring structure.

[0034] Among them, see Figures 1-4 The mounting bracket 2 is set inside the housing 7, and a movable block 12 is movably set on the mounting bracket 2. The movable block 12 and the mounting bracket 2 are connected by an electromagnetic ring structure sleeved on the mounting bracket 2 and a spring, so that the movable block 12 can move left and right on the mounting bracket 2, thereby preventing the cables from getting tangled when they are retracted.

[0035] Among them, see Figure 3 and Figure 4 The spool 1 is mounted on the upper side of the movable block 12. The spool 1 can move synchronously with the left and right displacement of the movable block 12. A toothed ring 13 is coaxially connected on the left and right sides of the spool 1. The toothed ring 13 is driven to rotate by a drive component located on the side of the mounting bracket 2.

[0036] When working, after the cable source and the location of the pile foundation to be tested are set up, when retrieving the cable, the toothed ring 13 is rotated by the drive component, so that the reel 1 rotates to retract the cable. At this time, the electromagnetic ring structure is energized, thereby controlling the moving block 12 to move left or right on the mounting frame 2, thus effectively avoiding the problem of cable tangling.

[0037] Currently, the main method for winding cables is by manual operation, which is time-consuming, labor-intensive, and inefficient. The cables are also prone to tangling, leading to wear and other problems. Therefore, this solution designs an automatic cable winding device for pile foundation testing. The drive component works in conjunction with the toothed ring 13 to rotate the reel 1 and wind up the cable, eliminating manual operation, saving time, and improving work efficiency. At the same time, the reel 1 can be displaced on the mounting frame 2 through the electromagnetic ring structure, which prevents the cable from getting tangled during winding, further improving the overall work efficiency.

[0038] In this embodiment, see Figure 3 For mounting bracket 2; multiple mounting brackets 2 are arranged side by side in the housing 7, and each mounting bracket 2 is equipped with a corresponding reel 1. Multiple reels 1 are driven by the same drive component to realize the synchronous winding and unwinding of cables, and each reel 1 corresponds to a probe, synchronously controlling the winding and unwinding of multiple probes; the mounting bracket 2 includes a support and a central rod 8; the support has a long rectangular base plate and support arms that are vertically upward at both ends of the long rectangular base plate. The long rectangular base plate is fixed to the inner bottom surface of the housing 7. A central rod 8 is horizontally connected to the top end of the two support arms (i.e., the upper part of the support). One end of the central rod 8 is connected to the left support arm, and the other end is connected to the right support arm (the central rod 8 is parallel to the long rectangular base plate). Fixed magnetic rings are inserted at the left and right ends of the central rod 8 (i.e., near the inner side of the support wall). At the same time, the center of the moving block 12 has a mounting hole so that the moving block 12 is sleeved on the central rod 8. Moving magnetic rings are fixed on the left and right sides of the moving block 12 respectively.

[0039] Furthermore, the fixed magnetic ring is divided into a first ring 3 and a second ring 4, while the movable magnetic ring is divided into a third ring 5 and a fourth ring 6. The first ring 3 and the third ring 5 are arranged opposite each other, and the second ring 4 and the fourth ring 6 are arranged opposite each other. Therefore, when the power is applied, the first ring 3 and the third ring 5 are energized and attract each other, at which time the movable block 12 moves to the left. When the second ring 4 and the fourth ring 6 are energized and attract each other, the movable block 12 moves to the right.

[0040] It should be noted that in this solution, three mounting brackets 2 are arranged side by side inside the housing 7, which can simultaneously retract and extend three cables. In actual applications, the structure can be added or removed according to the actual needs of cable retraction and extension, so as to achieve the purpose of synchronous retraction and extension and control of multiple cable probes.

[0041] Furthermore, a buffer spring 9 is provided between the first ring 3 and the second ring 4, and a buffer spring 9 is also provided between the third ring 5 and the fourth ring 6. The two ends of the buffer spring 9 are connected to the side of the electromagnetic ring. The buffer spring 9 is sleeved on the outside of the central rod 8. When the electromagnetic ring is de-energized, the moving block 12 will be reset due to the action of the buffer spring 9.

[0042] In this embodiment, see Figure 3 and Figure 4 The drive component is located on the rear side of the mounting frame 2. It drives multiple spools 1 on the mounting frame 2 to rotate. The drive component includes a long column 10 and a support. The support includes a base and two side arms perpendicular to the base (the side arms are located on the left and right ends of the base). The base is fixedly connected to the inner bottom surface of the outer casing 7. A rotatable long column 10 is horizontally connected to the top of the two opposite side arms. The long column 10 is a multi-toothed long cylinder with multiple toothed surfaces on its outer periphery. These teeth mesh with the toothed rings 13 on both sides of the spools 1. At the same time, one end of the long column 10 is connected to a motor 11. The motor 11 causes the long column 10 to rotate, thereby driving the meshing toothed rings 13 to rotate, thus causing the spools 1 to rotate for automatic winding.

[0043] Furthermore, see Figure 4 The total length of the long column 10, which serves as the driving component, extends from the leftmost to the rightmost of the multiple mounting brackets 2. When the moving block 12 on the mounting bracket 2 moves left and right on the central rod 8, the toothed ring 13 can mesh with the teeth of the long shaft, thereby realizing the rotation of the reel 1 to take in the line.

[0044] In this embodiment, see Figures 1-3 For the outer casing 7, multiple cable through holes are arranged side by side on one side frame surface of the outer casing 7. The multiple cable through holes are spaced apart from each other, and the cable through holes correspond to multiple parallel mounting brackets 2. The cable wound on each reel 1 is released and retrieved through the cable through holes. The outer casing 7 is a sealed structure, connected to the outside world only through the cable through holes, which can protect the internal structure and adapt to the harsh environment in the field.

[0045] Furthermore, see Figure 1 and Figure 7 For the cable through hole, a cleaning tube 14 is coaxially connected to the cable through hole on the outer side of the frame surface of the housing 7 (located at the cable through hole position). The cleaning tube 14 is a short cylindrical tube, and the inner wall of the cleaning tube 14 is provided with bristles 15 around the circumference. The bristles 15 are set directly facing the cable. When the cable is retracted inward by the rotation of the cable wheel 1, the bristles 15 can effectively remove the dirt and impurities attached to the cable and play a cleaning role.

[0046] The motor 11 is started to rotate the multi-toothed column 10, which in turn causes the meshing toothed ring 13 to rotate. Since the toothed ring 13 is connected to the reel 1, the multiple reels 1 on the multiple mounting brackets 2 rotate synchronously to take in the cable and retract it into the housing 7. At this time, when the cable is retracted through the cable through hole, the bristles 15 in the through hole clean the dust and dirt on the outside of the cable to prevent it from being brought into the housing. At the same time, the electromagnetic ring structure is energized, thereby controlling the moving block 12 to move left or right on the mounting bracket 2, thereby effectively preventing the cable from getting tangled.

[0047] Currently, when conducting pile foundation testing, cables need to be wound up and down manually. This manual winding is inefficient, time-consuming, and causes excessive wear due to cable tangling. Current automatic cable winding devices are complex in structure and cannot simultaneously wind up and down multiple cables. When winding up cables in the field, the cables are often covered in mud, which can cause dirt and grime on the device and the cables themselves, making it difficult to clean them in time. This solution uses multiple mounting frames 2 with reels 1 arranged side by side. The rotation of multiple reels 1 is controlled by the same long column 10. The long column 10 has multi-faceted teeth that mesh with the toothed rings 13 on the reels 1, thus achieving simultaneous winding up and down of multiple cables. At the same time, a movable block 12 that can move left and right is provided on the mounting frame 2. The movable block 12 moves through the cooperation of an electromagnetic ring and a spring, thus preventing tangling during winding. A cleaning tube 14 is also provided on the outside of the winding channel, and the bristles 15 inside the tube remove the mud and impurities attached to the cable.

[0048] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
