Description

Technical Field

[0001] This utility model relates to the field of probe rod pulling technology, and more specifically, to a multi-wedge block linkage probe rod puller. Background Technology

[0002] A probe puller is a tool or device specifically designed to pull out probes inserted into the ground or other objects. In geotechnical engineering projects such as building foundation construction, tunnel engineering, and slope treatment, probes are required for geological exploration, anchor pull-out tests, and other tasks. The probe puller is an important tool to ensure the smooth progress of these tasks, as it can accurately pull out the probe and provide reliable data support for engineering design and construction.

[0003] A search revealed that Chinese Patent CN218813618U discloses a probe rod extraction device, which includes a probe rod with a connecting hole at its upper end; it also includes a hollow sleeve with several pointed conical rods evenly distributed on the bottom surface of the sleeve, and a truncated cone threaded to the upper end of the sleeve. This utility model can extract the probe rod with minimal effort, and the extraction process keeps the probe rod in a vertical direction, preventing bending damage.

[0004] When the above-mentioned rod-pulling device is used for probes, it is inconvenient to pull out probes of different diameters. When facing a probe with a diameter smaller than the set value, a large gap will appear between the through hole of the truncated cone and the probe. During the rod-pulling process, the probe cannot be effectively supported and positioned, and is prone to shaking. This not only affects the stability of the rod-pulling and makes the rod-pulling operation difficult, but may also cause the probe to collide with other parts of the device due to shaking, causing damage to the surface of the probe and reducing the service life of the probe. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a multi-wedge block linkage probe puller, which aims to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-wedge linkage probe puller, comprising a fixed frame, two support frames, and a probe, wherein the top ends of the two support frames are fixedly connected to the fixed frame, the top end of the probe passes through the fixed frame, and an adjustment assembly is provided on the fixed frame. The adjustment assembly includes a positive and negative lead screw, multiple sliders, a sliding rod, two first U-shaped plates, multiple vertical plates, and two second U-shaped plates. Both ends of the positive and negative lead screw are movably connected to the fixed frame via bearings, and both ends of the sliding rod are fixedly connected to the fixed frame. The multiple sliders are movably sleeved on the positive and negative lead screw and the sliding rod, and one side of each slider is fixedly connected to the two first U-shaped plates. The top and bottom ends of the multiple vertical plates are fixedly connected to the two second U-shaped plates and the two first U-shaped plates, respectively. A pull-out assembly is provided on the first U-shaped plates.

[0007] Furthermore, a handle is fixedly connected to one end of the positive and negative lead screws, and a friction ring is movably disposed on the handle, with one side of the friction ring fixedly connected to the fixed frame.

[0008] As can be seen, in the above technical solution, the friction ring can increase the friction between the handle and the fixed frame.

[0009] Furthermore, the pulling assembly includes two wedge cylinders, multiple rotating shafts, a stepper motor, and a transmission mechanism. The stepper motor is fixedly installed on the front side of one of the first U-shaped plates, and the output shaft end of the stepper motor is fixedly connected to one of the rotating shafts. The number of pulling assemblies is two.

[0010] Furthermore, one end of each of the plurality of rotating shafts is fixedly connected to two wedge cylinders, and the other end of each of the plurality of rotating shafts is movably connected to the first U-shaped plate and the second U-shaped plate through bearings, wherein two of the rotating shafts are connected to each other through a transmission mechanism.

[0011] Furthermore, a mounting bracket is fixedly connected to the top of the fixed frame, and a limiting component is provided on the mounting bracket. The limiting component includes a limiting plate, a gasket, two springs, a movable bracket, a lead screw, and a threaded sleeve, and there are two mounting brackets and two limiting components.

[0012] Furthermore, one side of the limiting plate is fixedly connected to the gasket, the two ends of the two springs are respectively fixedly connected to the mounting bracket and the limiting plate, the movable bracket is fixedly installed on the other side of the limiting plate near the top edge, and one end of the lead screw passes through the movable bracket and the threaded sleeve and is fixedly connected to the mounting bracket.

[0013] It can be seen that the above technical solution is designed to facilitate limiting the front and rear sides of the probe.

[0014] Furthermore, a limiting rod is fixedly connected to one side of the mounting frame, and one end of the limiting rod passes through the movable frame.

[0015] As can be seen, in the above technical solution, the movable frame slides on the limiting rod, and the limiting rod can prevent the movable frame from deflecting.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] 1. This utility model can drive two first U-shaped plates to move towards each other by rotating the handle. The two first U-shaped plates can then drive two second U-shaped plates to move towards each other through multiple vertical plates, thereby adjusting the distance between the two lifting components. When the stepper motor works, two wedge cylinders rotate. Similarly, another stepper motor is started, and the two stepper motors rotate in opposite directions. The probe can be pulled out through multiple wedge cylinders. The linkage structure makes it convenient to pull out probes of different diameters.

[0018] 2. This utility model, by rotating the threaded sleeve and moving it away from the mounting frame, allows the two springs to rebound and drive the limiting plate and shims to move horizontally. Similarly, by adjusting the position of the other limiting plate, the front and rear sides of the probe rod are limited by the two limiting plates and two shims. Similarly, the moving frame is moved horizontally and brought closer to the mounting frame, and then the moving distance of the moving frame is limited by the threaded sleeve, ensuring the probe rod is stable during the extraction process. The structure is simple and easy to use. Attached Figure Description

Detailed Implementation

[0026] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] Refer to the instruction manual appendix Figure 1-5 The multi-wedge linkage probe puller of this embodiment includes a fixed frame 1, two support frames 4, and a probe 7. The top ends of the two support frames 4 are fixedly connected to the fixed frame 1. The top end of the probe 7 passes through the fixed frame 1. An adjustment assembly 2 is provided on the fixed frame 1. The adjustment assembly 2 includes a positive and negative lead screw 201, multiple sliders 202, a slide rod 203, two first U-shaped plates 204, multiple vertical plates 205, and two second U-shaped plates 206. The number of sliders 202 is four. Both ends of 201 are movably connected to the fixed frame 1 via bearings. Both ends of the slide rod 203 are fixedly connected to the fixed frame 1. Multiple sliders 202 are movably sleeved on the positive and negative lead screws 201 and the slide rod 203 respectively. One side of each slider 202 is fixedly connected to two first U-shaped plates 204. The top and bottom ends of multiple upright plates 205 are fixedly connected to two second U-shaped plates 206 and two first U-shaped plates 204 respectively. A pull-out assembly 3 is provided on the first U-shaped plate 204.

[0028] Furthermore, a handle 207 is fixedly connected to one end of the positive and negative lead screw 201. A friction ring 208 is movably disposed on the handle 207, and one side of the friction ring 208 is fixedly connected to the fixed frame 1. The pull-out assembly 3 includes two wedge cylinders 301, multiple rotating shafts 302, a stepper motor 303, and a transmission mechanism 304. The stepper motor 303 is fixedly installed on the front side of one of the first U-shaped plates 204, and the output shaft end of the stepper motor 303 is fixedly connected to one of the rotating shafts 302. There are two pull-out assemblies 3. One end of each of the multiple rotating shafts 302 is fixedly connected to the two wedge cylinders 301, and the other end of each of the multiple rotating shafts 302 is movably connected to the first U-shaped plate 204 and the second U-shaped plate 206 through bearings. The two rotating shafts 302 are connected to each other through the transmission mechanism 304.

[0029] Furthermore, a mounting frame 5 is fixedly connected to the top of the fixed frame 1. A limiting component 6 is provided on the mounting frame 5. The limiting component 6 includes a limiting plate 601, a gasket 602, two springs 603, a movable frame 604, a lead screw 605, and a threaded sleeve 606. There are two mounting frames 5 and two limiting components 6. One side of the limiting plate 601 is fixedly connected to the gasket 602. The two ends of the two springs 603 are fixedly connected to the mounting frame 5 and the limiting plate 601, respectively. The movable frame 604 is fixedly installed on the other side of the limiting plate 601 near the top edge. One end of the lead screw 605 passes through the movable frame 604 and the threaded sleeve 606 and is fixedly connected to the mounting frame 5. A limiting rod 607 is fixedly connected to one side of the mounting frame 5, and one end of the limiting rod 607 passes through the movable frame 604.

[0030] Rotating the threaded sleeve 606 away from the mounting bracket 5 causes the two springs 603 to rebound, which in turn moves the limiting plate 601 and the shim 602 horizontally. Similarly, adjusting the position of the other limiting plate 601 limits the front and rear sides of the probe 7 through the two limiting plates 601 and the two shims 602. Similarly, moving the moving frame 604 horizontally and bringing it closer to the mounting bracket 5 limits the movement distance of the moving frame 604 through the threaded sleeve 606. This limits the movement distance of the limiting plate 601, ensuring the probe 7 is stable during the pulling process. The structure is simple and easy to use. At the same time, the moving frame 604 slides on the limiting rod 607, which prevents the moving frame 604 from deflecting.

[0031] The usage method of this embodiment is as follows:

[0032] In use, the two support frames 4 are placed on the ground, and the probe 7 is located between the two first U-shaped plates 204. Rotating the handle 207 drives the forward and reverse lead screws 201 to rotate. The friction ring 208 increases the friction between the handle 207 and the fixed frame 1. Since two sliders 202 are threadedly connected to the forward and reverse lead screws 201, and the other two sliders 202 cooperate with the slide rod 203 to restrict the rotation of the two first U-shaped plates 204, the forward and reverse lead screws 201 can drive the two first U-shaped plates 204 to move towards each other. The two first U-shaped plates 204, in turn, drive the two second U-shaped plates 206 to move towards each other via multiple vertical plates 205, thereby adjusting the distance between the two lifting components 3. The stepper motor 303 is started, and its operation drives one of the rotating shafts 302 and one of the wedge cylinders 301 to rotate. One rotating shaft 302 can drive another wedge cylinder 301 to rotate through the transmission mechanism 304. Similarly, another stepper motor 303 is started, and the two stepper motors 303 rotate in opposite directions. Since the surface of the wedge cylinder 301 is evenly distributed with wedges, as the wedge cylinder 301 continues to rotate, a relative displacement occurs between the wedge and the probe 7. The wedge applies a thrust along the probe axial direction to the probe 7, thereby gradually pulling the probe 7 out from its initial position. Therefore, the probe 7 can be pulled out through multiple wedge cylinders 301. The linkage structure makes it convenient to pull out probes 7 of different diameters. Probes with common smaller diameters (such as 10mm) to larger diameters (such as 50mm) can all be adapted through this adjustment structure. It is worth noting that the transmission mechanism 304 includes a belt and two pulleys, and the two pulleys are respectively mounted on the two rotating shafts 302.

Electrical control components not mentioned in this technical solution are not shown in the figures because they are existing technologies, and will not be described here.

[0034] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
