Description

Technical Field

[0001] This utility model relates to the field of geological exploration technology, specifically to an auxiliary device for extracting a power penetrometer. Background Technology

[0002] Dynamic penetrometers are commonly used equipment in geological exploration. They are used to drive probes and rods into the soil layer, and the difficulty of driving them in determines changes in the soil layer, thereby analyzing the mechanical properties of the soil and evaluating its engineering characteristics.

[0003] In actual operation, after the dynamic penetrometer completes soil layer detection, the probe penetrates deep into the soil layer, especially when the extended probe rod is inserted into a deeper layer of soil. The soil generates a large frictional force on the probe rod and probe, and the negative pressure that may be formed in the hole makes the extraction of the dynamic penetrometer a very challenging task.

[0004] Currently, the most common method for extracting power penetration testers (PPTs) relies on manual operation. This method not only consumes a lot of manpower, requiring multiple workers to work together, but also involves extremely high labor intensity and low work efficiency. In cases with complex geological conditions, such as highly cohesive soil layers or soil layers with obstacles, manual extraction is almost impossible. Even with the assistance of large mechanical equipment, it is difficult to implement in exploration areas with narrow spaces or inconvenient transportation. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an auxiliary device for extracting a power penetrometer, so as to solve the problems of difficulty in extracting a power penetrometer from the soil layer and the laborious and inefficient nature of the existing extraction methods.

[0006] According to an embodiment of this utility model, an auxiliary device for retrieving a power penetrometer includes a base with two support arms mirror-imagely arranged at one end of the base; a support unit including an adjusting plate movably mounted on the two support arms and a telescopic member hinged to the adjusting plate for height adjustment, with fixed pulleys at both ends of the top of the telescopic member; and a lifting unit including a winch mounted on the base and a steel wire rope detachably mounted on the top of the support unit with one end mounted on the winch and the other end passing over the two fixed pulleys, with a movable pulley on the steel wire rope for hooking and lifting the penetrometer, and the winch for lifting the movable pulley.

[0007] Compared with existing technologies, this utility model has the following advantages: The base and mirror-mounted support arm provide stable bottom support for the device; the winch in the lifting unit provides continuous and stable mechanical pulling force, replacing traditional manual labor or large equipment for extraction, fundamentally solving the problem of time and labor costs. The combination of "fixed pulley + movable pulley" in the lifting unit forms a simple pulley system: the fixed pulley changes the direction of the pulling force, ensuring the wire rope tension is vertically upward, reducing additional resistance caused by directional deviation; the movable pulley amplifies the winch's pulling force, significantly reducing the power input required for extraction. The telescopic component in the support unit is height-adjustable, and the adjustment plate is movably mounted on the support arm, allowing flexible adjustment of the pulley system's height and position according to the penetrometer's burial depth and on-site conditions, ensuring the pulling force direction is consistent with the penetrometer's axis, maximizing pulling force utilization, and further improving extraction efficiency.

[0008] Preferably, the telescopic component includes a first column, a second column, and a third column. One end of the second column is slidably disposed inside the first column, and one end of the third column is slidably disposed inside the second column. The first column, the second column, and the third column are each provided with an array of multiple sets of adjustment holes, and corresponding pins are inserted into the corresponding adjustment holes.

[0009] Preferably, the adjustment plate is provided with a mounting base, and one end of the first column is hinged to the mounting base.

[0010] Preferably, the mounting base has multiple sets of limiting holes, and the first column is detachably provided with an adjusting pin, which is inserted into any one of the limiting holes.

[0011] Preferably, a cantilever is provided at the top of the third column, and two fixed pulleys are respectively provided at both ends of the cantilever, with the wire rope passing over the two fixed pulleys.

[0012] Preferably, a hook is provided on the cantilever, and a connecting ring is provided at the end of the wire rope away from the winch, with the connecting ring hooked onto the hook.

[0013] Preferably, a semi-circular groove is provided on the adjusting plate.

Detailed Implementation

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0022] like Figures 1 to 4 As shown in the figure, this utility model embodiment proposes an auxiliary device for retrieving a power penetrometer, which includes a base 10, with two support arms 11 mirror-arranged at one end of the base 10; a support unit, including an adjustment plate 20 movably arranged on the two support arms 11 and a telescopic member hinged to the adjustment plate 20 with adjustable height, and fixed pulleys 371 provided at both ends of the top of the telescopic member; and a lifting unit, including a winch 13 arranged on the base 10, and a wire rope 34 with one end arranged on the winch 13 and the other end passing over the two fixed pulleys 371 and detachably arranged on the top of the support unit, with a movable pulley 35 arranged on the wire rope 34, the movable pulley 35 being used to hook and lift the penetrometer, and the winch 13 being used to lift the movable pulley 35.

[0023] The detailed working process of this embodiment is as follows: The base 10 and the mirror-mounted support arm 11 provide a stable bottom support for the device. The winch 13 in the lifting unit provides continuous and stable mechanical pulling force, replacing traditional manual labor or large equipment for extraction, fundamentally solving the problem of time and labor costs. At the same time, the combination of "fixed pulley 371 + movable pulley 35" in the lifting unit forms a simple pulley group: the fixed pulley 371 changes the direction of the pulling force, ensuring that the tension of the wire rope 34 is vertically upward, reducing the additional resistance caused by directional deviation; the movable pulley 35 can amplify the pulling force of the winch 13, significantly reducing the power input required for extraction, and can overcome the friction of the soil layer on the penetrometer with less mechanical power, solving the problem of extraction difficulty; the telescopic component in the support unit is height-adjustable, and the adjustment plate 20 is movably set on the support arm 11, which can flexibly adjust the height and position of the pulley group according to the burial depth of the penetrometer and the on-site working conditions, ensuring that the pulling force direction is consistent with the axis of the penetrometer, maximizing the utilization rate of the pulling force, and further improving the extraction efficiency.

[0024] like Figure 4 As shown, the telescopic component includes a first column 31, a second column 32, and a third column 33. One end of the second column 32 is slidably disposed inside the first column 31, and one end of the third column 33 is slidably disposed inside the second column 32. Multiple sets of adjustment holes 311 are arrayed on the first column 31, the second column 32, and the third column 33, and corresponding pins 36 are inserted into the corresponding adjustment holes 311.

[0025] The detailed working process of this embodiment is as follows: The three-level column nesting design can achieve a wide range of height adjustment through step-by-step stretching. It can flexibly adjust the height position of the fixed pulley 371 according to the burial depth of the power penetrometer and the site terrain (such as uneven survey sites), ensuring that the tension direction of the wire rope 34 is always consistent with the axis of the penetrometer, avoiding tension deviation caused by insufficient height, and maximizing efficiency.

[0026] The adjustment holes 311 of the array cooperate with the pins 36 to achieve graded fixation of the height. When the column is stretched to the target height, the pins 36 are inserted into the corresponding aligned adjustment holes 311, which can mechanically lock the relative sliding of the column and ensure that the telescopic component does not sink or retract when subjected to the reaction force of pulling out the probe, thus providing a stable support reference for the fixed pulley 371.

[0027] The insertion and removal of the pin 36 does not require professional tools and can be completed by one person: pull out the pin 36 when stretching, adjust to the target height, align with the adjustment hole 311, and then insert the pin 36 to fix it. The whole process is fast and efficient.

[0028] like Figure 4 As shown, the adjustment plate 20 is provided with a mounting base 30, and one end of the first column 31 is hinged to the mounting base 30.

[0029] The detailed working process of this embodiment is as follows: the first column 31 is hinged on the mounting base 30 and can rotate around the hinge point at a certain angle so that the telescopic component can adapt to the tilt angle of the probe or the terrain of the site.

[0030] In non-operational state, the first column 31 can be folded around the hinge point to be parallel to the adjustment plate 20, reducing the overall size of the device, saving transportation and storage space, and improving portability. It can also be rotated around the hinge point at a certain angle to be used as a trolley handle for easy pushing of the device.

[0031] like Figure 4 As shown, the mounting base 30 has multiple sets of limiting holes 38, and the first column 31 is detachably provided with an adjusting pin 39, which is inserted into any one of the limiting holes 38.

[0032] The detailed working process of this embodiment is as follows: In the working state, by adjusting the pin 39 and the limiting hole 38, the first column 31 can be precisely adjusted to support the direction according to the burial angle of the penetrometer or the terrain of the site, so as to ensure that the tension of the wire rope 34 coincides with the axis of the penetrometer and maximize the extraction efficiency. Then, the adjusting pin 39 is inserted into the limiting hole 38 to complete the limiting fixation. In the non-working state, the telescopic part can also be rotated around the hinge point by a certain angle, and then the adjusting pin 39 is inserted into the limiting hole 38 to complete the limiting fixation, which is used as a trolley handle to facilitate the pushing of the device.

[0033] like Figure 4 As shown, a cantilever 37 is provided at the top of the third column 33, and two fixed pulleys 371 are respectively provided at both ends of the cantilever 37. The steel wire rope 34 passes around the two fixed pulleys 371.

[0034] The detailed working process of this embodiment is as follows: The cantilever 37 provides a stable mounting carrier for the fixed pulley 371. The fixed pulleys 371, which are symmetrically arranged at both ends, can change the direction of force on the wire rope 34, so that the tension of the winch 13 is applied more precisely to the movable pulley 35 after two turns. This double pulley layout can disperse the tension of the wire rope 34, reduce the load borne by a single fixed pulley 371, reduce the wear rate of the wire rope 34, and extend its service life.

[0035] like Figure 2 As shown, a hook 372 is provided on the cantilever 37, and a connecting ring 341 is provided at the end of the wire rope 34 away from the winch 13. The connecting ring 341 is hooked on the hook 372.

[0036] The detailed working process of this embodiment is as follows: the connecting ring 341 is hooked onto the hook 372, which allows for the fixing and separation of the wire rope 34 without tools, enabling quick connection of the lifting system when the penetrometer is installed or replaced. This makes it more convenient and faster to replace worn wire rope 34 or remove wire rope 34 in non-operational conditions, adapting to the fast-paced needs of field exploration.

[0037] like Figure 2 As shown, a semi-circular groove 21 is provided on the adjusting plate 20.

[0038] The detailed working process of this embodiment is as follows: The setting of the semi-circular groove 21 can avoid the adjustment plate 20 from interfering with the wire rope or the penetrometer, ensuring that the tension of the wire rope 34 coincides with the axis of the penetrometer, and maximizing the extraction efficiency.

[0039] like Figure 1 As shown, the base 10 and the bottom of the two support arms 11 are all equipped with rollers 14.

[0040] The detailed working process of this embodiment is as follows: The setting of the roller 14 allows the entire device to be easily pushed by manpower without the need for hoisting equipment. It is especially suitable for sites with complex terrain such as field surveys where large equipment is difficult to access. It facilitates rapid transfer between different detection points and reduces the manpower and time costs of equipment transportation.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
