Detailed implementation manners

[0031] Next, in combination with the detailed implementation manners, the present application will be further described. It should be noted that, on the premise of no conflict, the following-described embodiments or technical features can be arbitrarily combined with each other to form new embodiments.

[0032] In the description of the present application, it should be noted that for orientation terms, such as terms "center", "transverse", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., the indicated orientation and position relationships are based on the orientation or position relationships shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and should not be construed as limiting the specific protection scope of the present application.

[0033] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and do not have to be used to describe a specific order or sequence.

[0034] One preferred embodiment of the present application is as Figures 1 to 11 shown. A manual and electric tensioner includes a support assembly 1, a traction assembly 3, and a drive assembly 2; the traction assembly 3 and the drive assembly 2 are cooperatively installed on the support assembly 1. When it is necessary to pull out the anchor pile 400 buried underground, the traction assembly 3 and the anchor pile 400 can be first grasped and cooperated. Then, the support assembly 1 is driven manually or electrically to drive the drive assembly 2 to push the traction assembly 3 together with the grasped anchor pile 400 to move vertically along the support assembly 1 synchronously; or, the drive assembly 2 is driven manually or electrically to move vertically along the support assembly 1, and during the movement, the traction assembly 3 together with the grasped anchor pile 400 can be driven to move vertically along the support assembly 1 synchronously until the anchor pile 400 is pulled out of the ground.

[0035] In this embodiment, for the convenience of carrying, the length of the support assembly 1 is less than the length of the anchor pile 400. Thus, when the driving assembly 2 drives the traction assembly 3 to extract the anchor pile 400, if the anchor pile 400 cannot be completely extracted in one stroke, a cable can be tied to the pile body of the anchor pile 400, so that the traction assembly 3 grabs the cable to perform secondary or multiple extractions to complete the extraction of the anchor pile 400. The anchor pile 400 can also be lifted by padding hard objects at the lower end of the support assembly 1, so as to extract the anchor pile 400 by performing secondary or multiple extractions on the anchor pile 400.

[0036] In this embodiment, as Figure 1 , Figure 2 and Figures 5 to 8 shown, the driving assembly 2 includes a driving rod 21 and a driving member 22, and the support assembly 1 includes a support rod 11; the driving member 22 is installed on the support rod 11 and cooperates through a first force-increasing structure; the traction assembly 3 and the driving member 22 are in abutting cooperation, the driving rod 21 is installed on the traction assembly 3, and the driving rod 21 and the driving member 22 cooperate through a second force-increasing structure. When extracting the anchor pile 400, the support rod 21 can be driven manually or electrically, so that the driving member 22 moves vertically along the support rod 21 under the cooperation of the first force-increasing structure, and the traction force is amplified at the first stage. Furthermore, the driving member 22 pushes the traction assembly 3 and the anchor pile 400 to move vertically synchronously. The driving rod 21 can also be driven manually or electrically, so that the driving assembly 2 moves vertically along the support assembly 1 under the cooperation of the first force-increasing structure and the second force-increasing structure, and the traction force is amplified at the second stage, thereby driving the traction assembly 3 and the anchor pile 400 to move.

[0037] It can be understood that after the anchor pile 400 is buried in the ground, the anchor pile 400 is subjected to the soil retaining force, so that the extraction force required for extracting the anchor pile 400 is relatively large, and it cannot be achieved directly by manual labor or directly by a general electric device.

[0038] Therefore, according to the torque formula T = 9550P / n, when the power P remains unchanged, the lower the rotational speed n, the greater the output torque T. Therefore, in order to ensure that the driving assembly 2 is driven manually or electrically to drive the traction assembly 3 to extract the anchor pile 400, it is necessary to add a speed reduction and force-increasing structure, that is, the first force-increasing structure and the second force-increasing structure.

[0039] It can also be understood that in the initial stage of pulling out the anchor pile 400, the earth retaining force on the anchor pile 400 is the largest. At this time, generally, the first force increasing structure and the second force increasing structure need to cooperate simultaneously to pull out the anchor pile 400. As the pulling height of the anchor pile 400 increases, the earth retaining force on the anchor pile 400 gradually becomes smaller. The anchor pile 400 can be pulled out only through the first force increasing structure. At this time, the second force increasing structure is in a static state; since only the first force increasing structure is working, the speed of the vertical movement of the traction assembly 3 can be slightly increased, and thus the pulling efficiency of the anchor pile 400 can be accelerated.

[0040] In this embodiment, as Figures 5 to 8 shown, a worm segment 210 is provided in the middle of the driving rod 21, and the driving component 22 is a worm gear; the driving rod 21 is rotatably installed on the traction assembly 3 and meshes with the worm gear through the worm segment 210, thereby forming a second force increasing structure.

[0041] It can be understood that the second force increasing structure is a worm gear reduction structure. Generally, the transmission ratio of the worm gear reduction structure is above 10, that is, the force input to the driving rod 21 manually or electrically can be amplified by more than ten times through the second force increasing structure; at the same time, through the cooperation of the worm gear and the worm segment 210, the direction of the driving force can also be changed to facilitate the operation of the operator.

[0042] In this embodiment, as Figure 3 、 Figures 6 to 8 shown, a fitting hole 220 is provided at the center of the driving component 22; the support assembly 1 includes a support rod 11, and a fitting section is provided on the side wall of the support rod 11. The driving component 22 is installed on the support rod 11 so that the driving component 22 is fitted through the fitting hole 220 and the fitting section to form a first force increasing structure.

[0043] Specifically, there are various structures for the fitting hole 220 and the fitting section, including but not limited to the following two.

[0044] Structure 1: The fitting hole 220 is a threaded hole, and the fitting section is a threaded section; thus, a threaded connection structure is formed between the driving component 22 and the support assembly 1.

[0045] Structure 2: The fitting hole 220 is a lead screw hole, and the fitting section is a lead screw section. The lead screw hole and the lead screw section are fitted through balls; thus, a lead screw slider structure is formed between the driving component 22 and the support assembly 1.

[0046] It can be understood that when pulling out the pile by rotating the driving rod 21, whether it is a threaded connection structure or a lead screw slider structure, by fixing the support assembly 1, the driving component 22 drives the traction assembly 3 together with the anchor pile 400 to move vertically by rotating along the screw of the support assembly 1.

[0047] When pulling out a pile by rotating the support rod 11, due to the reverse self-locking of the first force-increasing structure, the driving component 22 cannot rotate. Instead, the driving component 22 can only move vertically along the support rod 11 to push the traction assembly 3 together with the anchor pile 400 to move vertically.

[0048] At the same time, both the threaded connection structure and the screw rod-slider structure are common force-increasing structures. Among them, the threaded connection structure is simple to process and easy to self-lock, but has low transmission efficiency and fast wear; the screw rod-slider structure is complex to process, but has small frictional resistance and long service life. Therefore, those skilled in the art can select according to actual needs in combination with the specific structures of the mating hole 220 and the mating section.

[0049] In this embodiment, as Figure 5 、 Figure 8 and Figure 11 shown, at least one end of the driving rod 21 is provided with a connection head 211, through which the operator can conveniently manually or electrically drive the driving rod 21 to rotate.

[0050] It can be understood that the structure of the connection head 211 can be an external hexagon structure, so that when the operator performs manual operation, the operator can directly cooperate with the connection head 211 through a wrench or a crank 600 to manually turn the driving rod 211. At the same time, when the operator performs electric operation, the operator can also directly cooperate with the connection head 21 of the electric wrench to electrically drive the driving rod 211.

[0051] One embodiment of the present application, as Figure 1 、 Figure 2 、 Figure 4 、 Figure 7 and Figure 8 shown, the traction assembly 3 includes a traction frame 31 and a tension hook 32; the tension hook 32 is detachably installed on one side of the traction frame 31 for grasping the anchor pile 400; the traction frame 31 is sleeved on the support assembly 1 and is in abutting cooperation with the driving component 22. Thus, when pulling out the anchor pile 400, the driving component 22 moves vertically under the drive of the driving rod 21 to drive the traction frame 31 to pull the anchor pile 400 to move synchronously through the tension hook 32.

[0052] It can be understood that in order to ensure that the driving component 22 can continuously move upward, it is necessary to ensure that the driving rod 21 moves upward synchronously with the driving component 22, so that the driving component 22 can always mesh with the driving rod 21. Thus, by installing the driving rod 21 on the traction frame 31 and making the traction frame 31 and the driving component 22 abut and cooperate with each other, when the driving rod 21 and the driving component 22 cooperate, the driving component 22 can drive the traction frame 31 and the driving rod 21 to move synchronously. At the same time, the movement of the traction frame 31 can also pull the anchor pile 400 through the tension hook 32 to move so as to pull out the pile.

[0053] In this embodiment, as Figure 4 , Figure 7 and Figure 8 shown, a through hole 311 is provided in the middle of the traction frame 31, and a placement cavity 310 is provided inside the traction frame 31; the support assembly 1 penetrates through the through hole 311, and the driving component 22 is located in the placement cavity 310 and abuts and cooperates with each other.

[0054] Specifically, when the driving rod 21 and the driving component 22 are rotationally meshed, in order to ensure the smoothness of the meshing, it is necessary to ensure the stability of the driving rod 21, that is, the traction frame 31 does not have radial movement relative to the support assembly 1. Furthermore, there are various matching structures between the traction frame 31 and the support assembly 1, including but not limited to the following two.

[0055] Matching structure one: The diameter of the through hole 311 can be adapted to the diameter of the support assembly 1, so that the traction frame 31 is slidably matched with the support assembly 1 through the through hole 311.

[0056] Matching structure two: A sliding bushing is installed in the placement cavity 310, and both ends of the sliding bushing are tightly fitted with the through hole 311, so that the traction frame 31 is slidably matched with the support assembly 1 through the sliding bushing.

[0057] It can be understood that the through hole 311 directly cooperates with the support assembly 1, and the structure is simple, but the wear on the support assembly 1 is relatively large. While installing a sliding bushing has a higher cost, but the wear on the support assembly 1 is relatively small. Thus, for the specific matching structure between the traction frame 31 and the support assembly 1, those skilled in the art can select according to actual needs.

[0058] In this embodiment, as Figure 4 and Figure 7 shown, a rotating seat 312 is provided on one side of the traction frame 31 away from the tension hook, and the rotating seat 312 is flush with the placement cavity 310; the driving rod 21 is rotatably installed on the rotating seat 312 and cooperates with the driving component 22.

[0059] It is understandable that the rotating seat 312 can be a bearing seat, so that the driving rod 21 is rotatably installed in the bearing seat through the bearing, thereby effectively reducing the friction resistance of the driving rod 21 during rotation, thereby reducing the labor intensity of the operator.

[0060] One of the embodiments of the present application is as follows: Figures 1 to 3 , Figure 7 and Figure 8 As shown, the support assembly 1 also includes an adjustment handle 12, which is T-shaped and detachably rotatably mounted on the top of the support rod 11. When the anchor pile 400 is pulled out by rotating the driving rod 21, the operator can set the lower ends of the support rods 11 against each other, and at the same time hold the upper end of the support rod 11 by the adjustment handle 12, so that the support assembly 1 is fixed, and then the spiral lifting of the driving component 22 is convenient to drive the traction assembly 3 to move vertically. When the anchor pile 44 is pulled out by rotating the support rod 11, the operator can directly drive the adjustment handle 12 manually or electrically to drive the support rod 11 to rotate, and then through the self-locking of the driving component 22 and the driving rod 21, the driving component 22 drives the traction assembly 3 to move vertically along the support rod 11.

[0061] It is understandable that if the driving component 22 drives the traction component 3 to move vertically along the support component 1 by spiral lifting, it is necessary to ensure that the support rod 11 remains stationary, so that the driving component 22 can spirally rise under the drive of the driving rod 21. In the present application, the support component 1 remains stationary during the pile pulling process by adjusting the grip of the handle 12, which can facilitate the operation of the operator and also facilitate the storage of the support component 1.

[0062] Specifically, Figure 3 As shown, a rotating hole 110 is provided at the top of the support rod 11, and the adjusting handle 12 cooperates with the rotating hole 110 through a rotating pin; thus, during the operation, the position of the adjusting handle 12 can be appropriately adjusted according to the needs of the operator to facilitate the operation of the operator.

[0063] In this embodiment, Figure 7 and Figure 10 As shown, at least one end of the adjustment handle 12 can be sleeved with an extension tube 500 to increase the holding force or driving force on the support rod 11.

[0064] It can be understood that according to the torque formula T = FL, when the force F remains unchanged, the larger the value of the lever arm L, the larger the value of the generated torque T. Therefore, when fixedly gripping the support rod 11, the gripping force for fixing the support assembly 1 can be increased by the extension tube 500. And when rotationally driving the support rod 11, the driving force on the support rod 11 can be amplified by the extension tube 500.

[0065] In this embodiment, as shown in FIGS. 1 to Figure 3 and Figures 7 to 9 shown, the support assembly 1 further includes a shoe base 13. The shoe base 13 is installed at the lower end of the support rod 11. Thus, when pulling out the anchor pile 400, the shoe base 13 is placed on the ground, so that the support assembly 1 abuts against the ground through the shoe base 13, thereby increasing the force-bearing area of the support assembly 1.

[0066] It can be understood that according to the formula P = F / S, when the force-bearing area S formed between the lower end of the support assembly 1 and the ground is smaller, the pressure P of the pressure F generated by the support assembly 1 on the ground is greater, and thus the support assembly 1 is more likely to sink into the ground, resulting in a reduction in the pulling efficiency of the anchor pile 400. Therefore, by adding the shoe base 13, the force-bearing area between the support assembly 1 and the ground can be increased, thereby reducing the pressure of the support assembly 1 on the ground to ensure the stability of the support assembly 1 during the pile pulling process.

[0067] Specifically, as shown in FIGS. Figure 3 and Figure 7 shown, a hemispherical hinge head 111 is provided at the lower end of the support rod 11, and the hemispherical hinge head 111 can be abutted and engaged with the hemispherical groove on the shoe base 13 to form a spherical hinge. Thus, during the pile pulling operation, the support rod 11 can be prevented from slipping sideways through the engagement, further improving the stability of the support assembly 1. At the same time, the spherical hinge can enable the support rod 11 to have a certain range of movement, facilitating the operation of the operator and avoiding interference in rigid installation.

[0068] In this embodiment, as shown in FIGS. Figure 3 and Figure 10 shown, at least one side of the shoe base 13 is provided with a mounting hole 130, and one end of the extension tube 500 is provided with a nut. Thus, when carrying the manual and electric stretcher, the extension tube 500 can be installed on the side of the shoe base 13 by passing a bolt through the mounting hole 130 and threadedly connecting it to the nut at the end of the extension tube 500, facilitating the carrying of the extension tube 500.

[0069] It can be understood that when the manual and electric stretcher is transported to the position of the anchor pile 400, the extension tube 500 can be removed by removing the bolt.

[0070] As shown in FIGS. Figure 9As shown, the manual and electric tensioner of the present application can not only be used for pulling out the anchor pile 400, but also for traction or expansion operations.

[0071] Specifically, as Figure 9 shown, when performing a traction operation, adjust the installation direction of the adjustment handle 12 so that the force application direction of the adjustment handle 12 is parallel to the force application direction of the tension hook 32. Thus, by applying a downward pressure to the adjustment handle 12, the support assembly 1 is kept vertically stationary, and then the drive rod 21 is driven to rotate manually or electrically, so that the drive component 22 drives the traction assembly 3 to grab the ground wire through the tension hook 32 for upward traction, realizing the adjustment of the tension and position of the ground wire.

[0072] Specifically, when performing an expansion operation, just adjust the installation direction of the tension hook 32 to meet the requirements of the expansion operation.

[0073] For easy understanding, the process of the drive assembly 2 driving the traction assembly 3 to pull out the pile can be elaborated in detail.

[0074] First, place the manual and electric tractor of the present application on the ground so that the support assembly 1 is vertically located on one side of the anchor pile 400 to be pulled out, and the lower end of the support rod 11 abuts against the shoe base 13 placed on the ground through the hemispherical hinge head 111. Then hold the adjustment handle 12 and operate the tension hook 32 to grab the top of the anchor pile 400 exposed on the ground.

[0075] Then, continue to hold the adjustment handle 12 so that the support assembly 1 maintains a stable vertical state.

[0076] Subsequently, the drive rod 21 is driven to rotate manually or electrically. At this time, the rotation of the traction frame 31 is restricted by the anchor pile 400, so that the spiral upward movement of the drive component 22 can only drive the traction frame 31 to move vertically upward synchronously. Furthermore, the traction frame 31 drives the anchor pile 400 to move upward through the tension hook 32 to realize the pulling out of the anchor pile 400.

[0077] If the pulling out stroke for one time is not enough, the height of the manual and electric tensioner of the present application can be adjusted for secondary or multiple pulling out. It is also possible to adjust the grabbing position of the tension hook 32 and the anchor pile 400, so as to realize the pulling out of the anchor pile 400 through the secondary or multiple strokes of the electric tensioner of the present application.

[0078] As the retaining force of the anchor pile 400 is small, the handle 12 can also be rotationally adjusted by lengthening the pipe 500, so that the support rod 11 rotates. At this time, since the driving member 22 is self-locked with the driving rod 21, the driving member 22 can only move along the axial direction of the support rod 11, thereby pushing the tensioning frame 31 to drive the tensioning hook 32 to grab the anchor pile 400 and move it upward to continue the pile pulling process until the anchor pile 400 is finally completely pulled out.

Those skilled in the art should understand that the present application is not limited by the above embodiments.
