Description

Technical Field

[0001] The present invention relates to the technical field of steel cage hoisting devices, and specifically to a hoisting bar device for a steel cage of a building construction pile foundation. Background Art

[0002] Generally, the prefabricated steel structures such as bored cast-in-place piles, dug piles, and columns are called steel cages. During the construction of high-rise buildings, according to requirements, it may be necessary to drive piles for the foundation. The method is to use a machine to punch holes and grind holes with water, and the hole depth reaches the design requirements. Then, lower the steel cage into the pile hole, and then insert a conduit for concrete pouring. When lowering the steel cage, generally a crane is used for hoisting. However, in the actual construction process, if the height of the steel cage is not high or the overall size is small, or the ground conditions near the construction location are poor (such as water accumulation or uneven ground), an excavator may also be directly used to lift and lower the steel cage. Compared with the need to unfold when using a crane for hoisting, the excavator is more flexible and has strong passability. However, when the excavator is used for hoisting, due to the limitation of the boom height, it is difficult to hoist and lower a steel cage with a height higher than the maximum lifting height of the bucket. Therefore, a hoisting bar device for a steel cage of a building construction pile foundation is proposed. Summary of the Invention

Specific embodiments

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Please refer to Figures 1 to 5 , in the embodiment of the present invention, a hoisting device for the steel cage of a building construction pile foundation includes a mounting arm 100, a clamping frame 200, hook claws 300, retracting and extending components 400, a first hydraulic rod 500, and a driving component 600. A mounting base 110 is installed at the top of the mounting arm 100, and the mounting base 110 is used for installation with the bucket rod of an excavator. Both ends on one side of the mounting arm 100 are installed with first support wheels 120. A plurality of convex plates 121 are equidistantly and fixedly connected to the circumferential side wall of the first support wheel 120. The first support wheel 120 supports the steel cage by clamping the horizontal bars of the steel cage. The number of clamping frames 200 is two, and they are respectively located on both sides of the mounting arm 100. The clamping frame 200 is rotatably connected to the mounting arm 100. The driving component 600 is fixedly installed on the mounting arm 100, and the driving component 600 is used to drive the first support wheel 120 to rotate in one direction. The first hydraulic rod 500 is fixedly installed on the mounting arm 100, and the mounting arm 100 is used to drive the two clamping frames 200 to open, close, and deflect. The number of hook claws 300 is two, and the hook claws 300 are used to hook and lift the horizontal bars of the steel cage. The number of retracting and extending components 400 is two, and the two retracting and extending components 400 are respectively installed on the clamping frame 200. The retracting and extending component 400 is used to lift and lower the hook claws 300.

[0034] Specifically, the mounting base 110 is rotatably mounted on the dipper arm of the excavator, and the dipper connecting rod is mounted on the mounting base 110. The mounting base 110 and the mounting arm 100 are driven by the excavator bucket cylinder to deflect forward and backward, so as to control the switching of the mounting arm 100 from the horizontal lying state to the vertical state. The hydraulic oil pump on the excavator supplies pressure to the first hydraulic rod 500 and the driving assembly 600. The opening and closing of the two clamping frames 200 are controlled by the first hydraulic rod 500. During use, when the mounting arm 100 lies horizontally and the two clamping frames 200 are opened, the mounting arm 100 is aligned with the steel reinforcement cage. Subsequently, the clamping frames 200 are controlled to clamp the steel reinforcement cage, and the convex plate 121 is clamped between the horizontal bars of the steel reinforcement cage, thereby limiting the steel reinforcement cage. When the steel reinforcement cage is moved to directly above the pile foundation well and released downward, the driving assembly 600 drives the two first supporting wheels 120 to deflect, so that the first supporting wheels 120 rotate to release the steel reinforcement cage. During the release, the position of the excavating arm and this device remains unchanged, so as to facilitate the continuous release of the steel reinforcement cage directly downward. When the top end of the steel reinforcement cage drops to the height position of the mounting arm 100, the ground staff will clamp the steel reinforcement cage (it is sufficient to insert several steel bars at the position of the pile foundation wellhead). The two clamping frames 200 are opened to release the holding of the steel reinforcement cage. Subsequently, this device is moved above the steel reinforcement cage, and the two clamping frames 200 deflect towards the middle, triggering the retracting and releasing assembly 400, so that the retracting and releasing assembly 400 releases the hook claws 300. Subsequently, the deflection of the clamping frames 200 is controlled to drive the hook claws 300 to move, so that the hook claws 300 hook the steel reinforcement cage. The lowering of the mounting arm 100 is controlled by the excavator arm to realize the lowering of the remaining part of the steel reinforcement cage, thereby realizing the hoisting of the steel reinforcement cage with a height exceeding the effective working height of the excavator arm.

[0035] Embodiment 1

[0036] Such as Figures 3 to 6As shown, in this embodiment, the embracing frame 200 includes two rocking arms 210, one end of the rocking arm 210 is rotatably connected to the mounting arm 100, the other end of the rocking arm 210 is rotatably connected to a supporting wheel 220, a fixing rod 230 is fixedly installed between one ends of the two rocking arms 210, an arc arm 231 is fixedly installed at the middle position of the fixing rod 230, the output end of the hydraulic rod 1 500 is rotatably installed between the two arc arms 231, the driving assembly 600 includes a hydraulic rod 2 610 and a transmission shaft 620, the hydraulic rod 2 610 is fixedly installed on the mounting arm 100, both ends of the mounting arm 100 are fixedly installed with a fixing seat 101, the supporting wheel 120 is rotatably installed at one end of the fixing seat 101 adjacent to the supporting wheel 120, the transmission shaft 620 is rotatably installed between the two fixing seats 101, and both ends of the transmission shaft 620 are fixedly sleeved with a bevel gear 2 6 50. A bevel gear 1 640 is fixedly installed at one end of the support wheel 120, and the bevel gear 1 640 is meshed with the adjacent bevel gear 2 650 for transmission. A one-way transmission module 630 is installed between the output end of the hydraulic rod 2 610 and the transmission shaft 620. The one-way transmission module 630 includes an inner cylinder 631, and the inner cylinder 631 is fixedly sleeved with the transmission shaft 620. A plurality of protrusions 1 632 are equidistantly arranged on the outer wall of the inner cylinder 631 in an annular manner. An outer cylinder 633 is arranged on the outer side of the inner cylinder 631. The output end of the hydraulic rod 2 610 is fixedly connected to the outer cylinder 633, and a plurality of protrusions 2 634 are equidistantly arranged on both ends of the inner wall of the outer cylinder 633 in an annular manner. The plurality of protrusions 2 634 at the top end of the outer cylinder 633 and the plurality of protrusions 2 634 at the bottom end are staggered with each other. Both ends of the protrusion 1 632 and one end of the protrusion 2 634 close to the middle position of the outer cylinder 633 are wedge-shaped.

[0037] In this embodiment, when the output end of the hydraulic rod 2 610 moves up and down, the outer cylinder 633 is driven to move up and down. When the outer cylinder 633 moves down, the multiple protrusions 2 634 at the lower end are staggered with the protrusion 1 632, and the multiple protrusions 2 634 at the upper end squeeze the protrusion 1 632 to drive the inner cylinder 631 to rotate half a grid in the forward direction (the distance between two adjacent protrusions 2 634 is one grid). When the outer cylinder 633 moves up, it also drives the inner cylinder 631 to rotate half a grid in the forward direction. The inner cylinder 631 drives the transmission shaft 620 to rotate, and the transmission shaft 620 drives the support wheel 120 to rotate through the bevel gear 2 650 and the bevel gear 1 640, thereby realizing the downward release of the support wheel 120 to the steel cage.

[0038] Embodiment 2

[0039] On the basis of the first embodiment, in order to compensate for the accidental shaking of the hook 300 and the interference with the steel cage when the support wheel 120 in the first embodiment releases the steel cage downward, the effect of stable downward lifting and releasing is achieved.

[0040] like Figures 6 to 7As shown in the figure, in this embodiment, the retracting and extending assembly 400 includes a winding wheel 460. The winding wheel 460 is rotatably installed at the other end of a rocker arm 210 at the bottom end of the clamping frame 200. A lifting rope 470 is wound and installed on the winding wheel 460. The bottom end of the lifting rope 470 passes downward through the adjacent rocker arm 210. The bottom end of the lifting rope 470 is fixedly connected to the hook claw 300 on the corresponding side. A card slot 461 is formed on the winding wheel 460. A plug rod 450 for clamping the card slot 461 is arranged on one side of the winding wheel 460. A traction rope 420 is fixedly connected between the plug rod 450 and the mounting arm 100. A support frame 440 is arranged on one side of the winding wheel 460. The plug rod 450 is slidably inserted into the top end of the support frame 440. A clamping rod 451 is fixedly connected to one end of the plug rod 450. The clamping rod 451 is clamped with the card slot 461. The other end of the plug rod 450 is fixedly connected to the traction rope 420. A return spring 452 is arranged between the clamping rod 451 and the support frame 440. The return spring 452 is movably sleeved on the plug rod 450. An extension rod 102 is fixedly installed on the mounting arm 100. One end of the traction rope 420 is fixedly installed with one end of the extension rod 102. A fixed shaft 430 is arranged on one side of the support frame 440. The bottom end of the fixed shaft 430 is fixedly installed with the adjacent rocker arm 210. A guide wheel 431 is rotatably connected to the top end of the fixed shaft 430. The traction rope 420 bypasses the guide wheel 431. A anti - detachment frame 432 is fixedly connected to the top end of the fixed shaft 430. A support rod 410 is fixedly connected to the bottom end of the fixed rod 230. The traction rope 420 passes through one end of the support rod 410.

[0041] During specific implementation, initially, the winding wheel 460 can be manually rotated to wind the lifting rope 470, so as to tighten the hook claw 300 below the rocker arm 210, avoiding the shaking of the hook claw 300. The card slot 461 is clamped by the clamping rod 451 to limit the release of the lifting rope 470 by the winding wheel 460. When the two clamping frames 200 deflect until the other ends of the rocker arms 210 are close to contacting each other, the traction rope 420 is tightened and pulls the plug rod 450, causing the plug rod 450 and the clamping rod 451 to move away from the winding wheel 460, thereby releasing the winding wheel 460. The hook claw 300 pulls the lifting rope 470 downward to drop, so that the lifting rope 470 is released, and thus the hook claw 300 is hung below the clamping frame 200 through the lifting rope 470, realizing the downward release of the hook claw 300 by operating the closing control of the clamping frame 200, so as to facilitate the hooking of the steel reinforcement cage by the hook claw 300.

[0042] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-described exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
