A vertical placement device for pile drivers

Abstract

This invention relates to a vertical placement device for pile drivers, applicable to the field of pile driver technology. The device includes a frame, a support base, a limiting ring, a hydraulic cylinder, a support sleeve, a resistance trolley, a support fork, a connecting shaft, and a pneumatic cylinder. With this structure, during pile driver placement, the top of the pile driver passes through the limiting ring, and the bottom of the pile driver is placed on the resistance trolley. Pushing the resistance trolley towards the support base allows the pile driver to rotate from a horizontal to a vertical position. After the resistance trolley reaches the bottom of the support base, the support fork is inserted into a storage slot at the bottom of the resistance trolley, supporting the bottom of the pile driver and ensuring its vertical placement. This facilitates the removal of the resistance trolley. When pile driving is required, the vertically placed pile driver quickly aligns with the top of the pile. The pneumatic cylinder pulls the connecting shaft, causing the support fork to rotate outward, releasing the support for the pile driver and facilitating vertical pile driving.

Description

Technical Field

[0001] The present invention relates to a vertical placement device, and more particularly to a vertical placement device for a pile driver applied in the field of pile driver technology. Background Technology

[0002] A pile driver is a long, inserted device that transmits hammering force to the top of a pile, which is used to drive the pile to the ground or below the water surface. Static pile driving refers to a pile driving method that uses static pressure to press precast piles into the soil section by section. This method saves steel bars and concrete and reduces project costs. In existing pipe pile construction, hammer driving is a common pile driving method, that is, to drive the precast pile to the predetermined depth by hammering.

[0003] Chinese patent CN202111046746.2 discloses "An Integrated Static Pile Driver Hydraulic Pile Driver". This invention uses a carrier vehicle to carry and move the pile driving assembly. Combined with the hydraulic drive system in the carrier vehicle to control the deflection of the crank arm and the adjustment hydraulic cylinder to control the deflection of the main pile driving support, the pile driving direction of the pile driving assembly can be adjusted. It is suitable for pile driving on uneven terrain, has high flexibility, and combines the top and side action of the pile driving device and the top action of the pile driving device to drive the pile, ensuring sufficient power for pile driving and effectively improving pile driving efficiency.

[0004] Existing pile drivers are usually placed horizontally on the construction site. Before pile driving, it is necessary to use hoisting equipment or other large equipment to flip the pile driver to a vertical position. As mentioned above, the invention uses a carrier vehicle in conjunction with a large boom to flip and grab the pile driver. If the pile driver can be placed vertically directly, the flipping process from horizontal to vertical can be reduced each time it is used, thus improving construction efficiency. Summary of the Invention

[0005] The technical problem that this invention aims to solve in view of the above-mentioned prior art is that the pile driver needs to be flipped from a horizontal position to a vertical position before construction. The hoisting and flipping operation is complicated and affects construction efficiency.

[0006] To address the aforementioned problems, this invention provides a vertical placement device for a pile driver, comprising a frame, a base fixedly connected to the bottom of the frame, a limiting ring slidably connected to the top of the frame, a pile driver fitted inside the limiting ring, a hydraulic cylinder fixedly connected to the middle of the base, a support sleeve fixedly connected to the output end of the hydraulic cylinder, a resisting trolley movably connected to the outside of the support sleeve, and the bottom end of the pile driver contacting the resisting trolley; a storage groove is provided at the bottom of the resisting trolley, and support forks are rotatably connected to both ends of the bottom of the support sleeve, with the support forks corresponding to the storage groove; a connecting shaft slidably connects the rear ends of the two support forks; a cylinder is fixedly connected to the bottom of the support sleeve, and the output end of the cylinder is fixedly connected to the middle of the connecting shaft.

[0007] In the above-mentioned vertical placement device for pile drivers, by passing the top end of the pile driver through the limiting ring and placing the bottom end of the pile driver on the resisting trolley, the resisting trolley is operated to push the pile driver towards the support base, thereby turning the pile driver from horizontal placement to vertical placement, which facilitates the direct use of the pile driver in the future.

[0008] As a further improvement of this application, the side cross-section of the resisting trolley is L-shaped, and rollers are fixedly connected to both ends of the internal storage slot. The L-shaped design of the resisting trolley facilitates the placement of the bottom of the pile driver in both horizontal and vertical positions.

[0009] As a further improvement of this application, the top of the roller is higher than the bottom surface of the resisting trolley. The roller is made of high-hardness steel and uses the roller to support the pile driver, which facilitates the removal of the resisting trolley after the pile driver is placed vertically.

[0010] As a further improvement of this application, the support fork is V-shaped and the included angle of the support fork is 90°-150°. The top surface of the support fork is flush with the top surface of the roller, which makes it easy for the bottom end of the pile feeder to be placed on the top of the support fork. The contact surface between the support fork and the bottom end of the pile feeder is larger than the contact surface between the roller and the bottom end of the pile feeder, which makes it easier to resist the removal of the trolley.

[0011] As another improvement of this application, the limiting ring consists of a front half ring and a rear half ring, and both ends of the front half ring and the rear half ring are fixedly connected with a set of rotating plates by bolts. The limiting ring can be disassembled into a front half ring and a rear half ring. The tightening of the front half ring and the rear half ring can be adjusted according to the diameter of the pile driver, so that the limiting ring can be fitted with pile drivers of different sizes.

[0012] As a further improvement to this application, the cross-section of the rear half ring is circular, and multiple rolling balls are sleeved on the outside of the rear half ring. When the pile driver is flipped to the tilted state, the pile driver rests on the rear half ring, and the rolling balls realize the rolling effect between the pile driver and the rear half ring, effectively reducing the friction between the pile driver and the rear half ring.

[0013] As another improvement of this application, sleeves are slidably connected to both ends of the frame, and a rotating shaft is rotatably connected to the outside of the sleeve. The rotating shaft is fixedly connected to the rotating plate group, and the first half and second half of the rotating plate group are flipped through the rotating shaft, which corresponds to the pile driver flipping from horizontal to vertical, effectively improving the stability of the pile driver flipping movement.

[0014] As a further improvement to this application, a guide outer cylinder is fixedly connected to the top of the rotating plate, and a guide inner cylinder is sleeved inside the guide outer cylinder. A guide roller is rotatably connected to one end of the guide inner cylinder near the pile driver, and the guide roller contacts the surface of the pile driver. The guide inner cylinder extends out from the guide outer cylinder, and the guide roller abuts against the surface of the pile driver to effectively clamp and restrict the pile driver.

[0015] As a further improvement to this application, the guide outer cylinder is set horizontally and parallel to the rotating shaft, so that the guide outer cylinder rotates with the rotating shaft while maintaining a horizontal state, thus continuously and effectively clamping and restricting the pile driver.

[0016] As a further improvement to this application, a guide cylinder is installed inside the guide inner cylinder. The output end of the guide cylinder is fixedly connected to the guide roller, and the cylinder body end of the guide cylinder is fixedly connected to the guide outer cylinder. The guide cylinder drives the telescopic movement of the guide inner cylinder, which facilitates the clamping, limiting and controlling of the pile driver.

[0017] In summary, when the pile driver is flipped and placed in this scheme, the top of the pile driver passes through the limiting ring, and the bottom of the pile driver is placed on the resisting trolley. The resisting trolley is pushed towards the support base, which flips the pile driver from a horizontal to a vertical position. After the resisting trolley is pushed to the bottom of the support base, the support fork is inserted into the storage slot at the bottom of the resisting trolley. The support fork supports the bottom of the pile driver, which is placed vertically, making it easy to remove the resisting trolley. When pile driving is required, the vertically placed pile driver is quickly aligned with the top of the pile, and the cylinder pulls the connecting shaft to rotate the support fork outward, releasing the support for the pile driver and facilitating vertical pile driving.

[0029] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0030] First implementation method:

[0031] Figure 1-4 The diagram shows a vertical placement device for a pile driver, comprising a frame 1, a base 2 fixedly connected to the bottom of the frame 1, a limiting ring 3 slidably connected to the top of the frame 1, a pile driver 4 fitted inside the limiting ring 3, a hydraulic cylinder 201 fixedly connected to the middle of the base 2, a mounting sleeve 202 fixedly connected to the output end of the hydraulic cylinder 201, a resisting trolley 203 movably connected to the outside of the mounting sleeve 202, the bottom of the pile driver 4 contacting the resisting trolley 203, the resisting trolley 203 having an L-shaped lateral cross-section, and rollers 208 fixedly connected to both ends of the storage groove 204, the L-shaped arrangement of the resisting trolley 203 facilitating the placement of the bottom of the pile driver 4 in both horizontal and vertical states;

[0032] When the pile driver 4 is flipped and placed, the top of the pile driver 4 passes through the limiting ring 3, and the bottom of the pile driver 4 is placed on the resisting trolley 203. The resisting trolley 203 is pushed towards the support base 2, so that the pile driver 4 is flipped from a horizontal state to a vertical state, and the pile driver 4 is changed from a horizontal placement to a vertical placement state, which prepares for the subsequent pile driving construction.

[0033] Figure 4-7As shown, the bottom of the resisting trolley 203 has a storage slot 204. Both ends of the bottom of the holder sleeve 202 are rotatably connected to holder forks 205, which are inserted into and correspond to the storage slot 204. A connecting shaft 206 is slidably connected between the rear ends of the two holder forks 205. A cylinder 207 is fixedly connected to the bottom end of the holder sleeve 202, and the output end of the cylinder 207 is fixedly connected to the middle of the connecting shaft 206. Rollers 208 are fixedly connected to both ends inside the storage slot 204, with the tops of the rollers 208 protruding above the bottom surface of the resisting trolley 203. The roller 208 is made of high-hardness steel. The roller 208 is used to support the pile driver 4, which makes it easier to resist the removal of the trolley 203 after the pile driver 4 is placed vertically. The support fork 205 is V-shaped and the included angle of the support fork 205 is 90°-150°. The top surface of the support fork 205 is flush with the top surface of the roller 208, which makes it easier for the bottom of the pile driver 4 to be placed on the top of the support fork 205. The contact surface between the support fork 205 and the bottom of the pile driver 4 is larger than the contact surface between the roller 208 and the bottom of the pile driver 4, which makes it easier to resist the removal of the trolley 203.

[0034] After the resisting trolley 203 is pushed to the bottom of the support base 2, the support fork 205 is inserted into the storage slot 204 at the bottom of the resisting trolley 203. The support fork 205 supports the bottom of the pile driver 4, so that the pile driver 4 is placed in a vertical position. The bottom of the pile driver 4 is placed on the top of the support fork 205. The contact surface between the support fork 205 and the bottom of the pile driver 4 is larger than the contact surface between the roller 208 and the bottom of the pile driver 4, which facilitates the removal of the resisting trolley 203. When pile driving is required, the vertically placed pile driver 4 quickly aligns with the top of the pile. The cylinder 207 pulls the connecting shaft 206 to rotate the support fork 205 outward, releasing the support for the pile driver 4, which facilitates the vertical pile driving of the pile driver 4.

[0035] Second implementation method:

[0036] Compared with the first embodiment, this embodiment mainly adds a front half circle 301 and a rear half circle 302. The specific added structure is as follows, and the rest of the structure is the same as the first embodiment.

[0037] Figure 1-3 and Figure 8-9As shown, the limiting ring 3 consists of a front half-ring 301 and a rear half-ring 302, and both ends of the front half-ring 301 and the rear half-ring 302 are fixedly connected to a set of rotating plates 303 by bolts. The limiting ring 3 can be disassembled into the front half-ring 301 and the rear half-ring 302. The tightening of the front half-ring 301 and the rear half-ring 302 can be adjusted according to the diameter of the pile driver 4, so that the limiting ring 3 can be fitted with pile drivers 4 of different sizes. Both ends of the frame 1 are slidably connected to sleeves 305, and the outside of the sleeves 305 is rotatably connected to a rotating shaft 306. The rotating shaft 306 is fixedly connected to the set of rotating plates 303. The rotating shaft 306 enables the flipping motion of the front half ring 301 and the rear half ring 302 on the rotating plate 303, corresponding to the flipping change of the pile feeder 4 from horizontal to vertical, effectively improving the stability of the flipping motion of the pile feeder 4. The rear half ring 302 has a circular cross-section, and multiple rolling balls 304 are sleeved on the outside of the rear half ring 302. When the pile feeder 4 flips to the tilted state, the pile feeder 4 rests on the rear half ring 302, and the rolling balls 304 realize the rolling effect between the pile feeder 4 and the rear half ring 302, effectively reducing the friction between the pile feeder 4 and the rear half ring 302.

[0038] Compared to the first embodiment, in this embodiment, when the pile driver 4 passes through the limiting ring 3, the operator tightens the bolts on the front half ring 301, the rear half ring 302, and the rotating plate 303 according to the diameter of the pile driver 4. This facilitates the fitting of the limiting ring 3 with pile drivers 4 of different sizes. During the process of the pile driver 4 flipping from a horizontal to a vertical state, the limiting ring 3 rotates around the rotating shaft 306, effectively improving the stability of the flipping motion of the pile driver 4. The rolling ball 304 realizes the rolling effect between the pile driver 4 and the rear half ring 302, effectively reducing the friction between the pile driver 4 and the rear half ring 302, thereby improving the service life of the device.

[0039] Figure 8-9 As shown, a guide outer cylinder 5 is fixedly connected to the top of the rotating plate 303. The guide outer cylinder 5 is horizontally arranged and parallel to the rotating shaft 306, so that the guide outer cylinder 5 rotates with the rotating shaft 306. At the same time, the guide outer cylinder 5 remains horizontal, continuously and effectively clamping and restricting the pile feeder 4. A guide inner cylinder 501 is sleeved inside the guide outer cylinder 5. A guide roller 502 is rotatably connected to one end of the guide inner cylinder 501 near the pile feeder 4, and the guide roller 502 contacts the surface of the pile feeder 4. The guide inner cylinder 501 extends out from the guide outer cylinder 5 and uses the guide roller 502 to abut against the surface of the pile feeder 4, effectively clamping and restricting the pile feeder 4. A guide cylinder 503 is sleeved inside the guide inner cylinder 501. The output end of the guide cylinder 503 is fixedly connected to the guide roller 502, and the cylinder body end of the guide cylinder 503 is fixedly connected to the guide outer cylinder 5. The guide cylinder 503 drives the extension and retraction movement of the guide inner cylinder 501, which facilitates the clamping and restricting control of the pile feeder 4.

[0040] Compared to the first embodiment, in this embodiment, after the first half-circle 301 and the second half-circle 303 are rotated and tightened according to the diameter of the pile driver 4, the guide cylinder 503 drives the guide inner cylinder 501 to extend out from the guide outer cylinder 5, and the guide roller 502 clamps and contacts the surface of the pile driver 4, which facilitates the clamping and control of the pile driver 4, keeps the pile driver 4 stable when placed, and facilitates the stability of the pile driver 4 during subsequent pile driving construction.

[0041] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this invention.
