Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to a steel cage hoisting device used for bridge cast-in-place pile construction. Background Art

[0002] The steel cage is a cage-shaped steel frame formed by tying together steel bars of corresponding diameters according to certain shape requirements. The steel cage mainly plays a tensile role, which is the same as the force of the longitudinal steel bars of the column. Since the compressive strength of concrete is high but the tensile strength is very low, when the steel cage is used to form a cast-in-place pile, the steel cage can restrain the concrete of the pile body so that it can withstand a certain axial tension.

[0003] See also Figure 1 The steel cage 1 includes a plurality of annular stiffening bars 101 arranged at intervals along the length direction of the steel cage 1 and a plurality of main bars 102 arranged around the stiffening bars 101 along the circumferential direction and welded and fixed to the stiffening bars 101, wherein the main bars 102 are parallel to the axis of the stiffening bars 101. During the construction of bridge cast-in-place piles, the steel cage hoisting device directly hoists the steel cage in a two-point hoisting manner, that is, the main hook and the auxiliary hook on the crane are hooked on the stiffening bars, and then the crane pulls the main hook and the auxiliary hook to lift the steel cage. However, after the main hook and the auxiliary hook are hooked on the stiffening bars, it is not easy for the main hook and the auxiliary hook to be accurately located on the same diameter of the circular ring surrounded by the stiffening bars. In the process of hoisting the steel cage, the hoisted steel cage is prone to tilt due to uneven force, making it difficult for the steel cage to be accurately and vertically placed in the pile hole.

[0034] Embodiment 1

[0035] See also Figure 1 - Figure 5 The utility model provides a technical solution: a steel cage hoisting device for bridge cast-in-place pile construction, comprising a connecting mechanism 2, a bearing plate 3 and a hanging ring 4, wherein the connecting mechanism 2 is multiple, and the multiple connecting mechanisms 2 are evenly arranged along the circumferential direction, the upper end of the connecting mechanism 2 is fixedly connected to the bearing plate 3, and the lower end of the connecting mechanism 2 is used for detachably connecting the stiffening bar 102 of the steel cage 1, and the hanging ring 4 is fixed on the bearing plate 3, and the hanging ring 4 is located at the center position of the arrangement path of the multiple connecting mechanisms 2. The connecting mechanisms 2 are evenly arranged along the circumferential direction, and the arrangement path of the connecting mechanisms 2 is a circular path, and the center position is the center position of the circular path.

[0036] When using the steel cage hoisting device for bridge bored pile construction of the utility model, the steel cage hoisting device for bridge bored pile construction of the utility model is placed on the end of one end of the steel cage 1, and the connecting mechanism 2 is directed toward the steel cage 1, and the lower ends of the plurality of connecting mechanisms 2 are connected to the reinforcing bar 102 closest to the end of the steel cage 1. Then a hook of the crane is hooked on the hanging ring 4, and the steel cage 1 can be hoisted by the crane and the steel cage hoisting device for bridge bored pile construction of the utility model. Since the connecting mechanism 2 is connected to the reinforcing bar 102, and since the plurality of connecting mechanisms 2 are evenly arranged in the circumferential direction, after the lower ends of the plurality of connecting mechanisms 2 are connected to the reinforcing bar 102 closest to the one end of the steel cage 1, the lower ends of the plurality of connecting mechanisms 2 can be evenly arranged in the circumferential direction on the reinforcing bar 102. When the crane lifts the steel cage 1, the steel cage 1 is evenly stressed and is not prone to tilting, thereby making it easier and more accurate to vertically place the steel cage 1 into the pile hole.

[0037] In this embodiment, the connecting mechanism 2 includes a fixing portion 21 and a connecting portion 22, wherein the fixing portion 21 is used to detachably connect the reinforcing bar 102, and the upper end of the connecting portion 22 is fixedly connected to the bearing plate 3, and the lower end is detachably connected to the fixing portion 21. With this structure, the lower end of the connecting mechanism 2 can be detachably connected to the reinforcing bar 102 closest to the one end of the steel cage 1.

[0038] In this embodiment, the fixing portion 21 includes a supporting component 211 and a connecting component 212. The supporting component 211 is used to support the stiffening rib 102 with its back facing the center of the circle surrounded by the stiffening rib 102. The supporting component 211 is recessed inward corresponding to the position of the stiffening rib 102 to form a first accommodating groove 5 for accommodating the stiffening rib 102. The first accommodating groove 5 cooperates with the stiffening rib 102. The inner end of the connecting component 212 is fixedly connected to the supporting component 211. The outer end of the connecting component 212 is located on the outer side of the stiffening rib 102. The lower end of the connecting portion 22 is used to detachably connect to the outer end of the connecting component 212. In this embodiment, the direction toward the center of the circle surrounded by the stiffening rib 102 is referred to as "inside", and the direction away from the center of the circle surrounded by the stiffening rib 102 is referred to as "outside". In the subsequent description, "inside" and "outside" have the same meaning.

[0039] The fixing part 21 is moved from the inner side of the end of the one end of the steel cage 1 to the stiffening rib 102, and the first receiving groove 5 is opposite to the stiffening rib 102, and then the stiffening rib 102 is clamped in the first receiving groove 5, so that the abutting component 211 can be connected to the stiffening rib 102, at which time the outer end of the connecting component 212 protrudes from the outer side of the stiffening rib 102, and then the lower end of the connecting part 22 is connected to the outer end of the connecting component 212. With this structure, the abutting component 211 can be connected to the stiffening rib 102, and the fixing part 21 can be connected to the stiffening rib 102.

[0040] After the steel cage 1 is placed in the pile hole, the lower end of the connecting portion 22 is separated from the outer end of the connecting component 212, and then the supporting component 211 and the connecting component 212 are moved toward the center of the circle surrounded by the stiffening ribs 102, so that the first accommodating groove 5 is separated from the stiffening ribs 102, and the supporting component 211 and the connecting component 212 can be removed from the stiffening ribs 102, and the fixing portion 21 can be removed from the stiffening ribs 102.

[0041] In this embodiment, the supporting component 211 is also used to support the main reinforcement 101 of the steel cage 1 with its back facing the center of the circle surrounded by the stiffening reinforcement 102. The supporting component 211 is recessed inward at the position corresponding to the main reinforcement 101 to form a second accommodating groove 6 for accommodating the main reinforcement 101. The upper end of the second accommodating groove 6 is located above the first accommodating groove 5, and the lower end is located below the second accommodating groove 6.

[0042] When the abutting assembly 211 is connected to the reinforcing bar 102, the second receiving groove 6 is opposite to the main bar 101, and the main bar 101 is stuck in the second receiving groove 6. With this structure, when the crane lifts the steel cage 1, the main bar 101 is stuck in the second receiving groove 6, so that the abutting assembly 211 can be stably connected to the steel cage 1, and the abutting assembly 211 is not easy to slide along the circumferential direction of the reinforcing bar 102.

[0043] In this embodiment, the supporting component 211 includes a plate body, the first accommodating groove 5 is formed by being recessed inward from a position of the plate body corresponding to the stiffening rib 102, the second accommodating groove 6 is formed by being recessed inward from a position of the plate body corresponding to the main rib 101, the first accommodating groove 5 is arranged in the horizontal direction, the second accommodating groove 6 is arranged in the vertical direction, the first accommodating groove 5 and the second accommodating groove 6 intersect vertically, and the intersection position of the first accommodating groove 5 and the second accommodating groove 6 is located in the middle of the first accommodating groove 5 and the middle of the second accommodating groove 6.

[0044] In this embodiment, the connecting portion 22 includes a connecting rope 221 and a connecting hook 222, the upper end of the connecting rope 221 is fixedly connected to the bearing plate 3, and the lower end is fixedly connected to the hook tail of the connecting hook 222; the connecting assembly 212 includes two connecting plates 2121, the inner ends of the two connecting plates 2121 are fixedly connected to the outer side surface of the lower end of the second abutting plate 2112, the two connecting plates 2121 are respectively located on both sides of the fourth groove 62, the outer ends of the two connecting plates 2121 are located on the outer side of the stiffening rib 102, the outer ends of the two connecting plates 2121 are both provided with connecting holes 8 in the transverse direction, and the connecting hook 222 is penetrated in the connecting holes 8 on the two connecting plates 2121. With this structure, the lower end of the connecting portion 22 can be detachably connected to the connecting assembly 212, and the lower end of the connecting portion 22 can be detachably connected to the fixing portion 21.

[0045] In this embodiment, the connecting hook 222 includes an anti-slip baffle 2221 arranged at the hook head of the connecting hook 222, and the anti-slip baffle 2221 is arranged on the inner side surface of the connecting hook 222, one end of the anti-slip baffle 2221 is fixedly connected to the inner side surface of the hook head of the connecting hook 222, and the other end of the anti-slip baffle 2221 protrudes toward the middle part of the inner cavity of the connecting hook 222.

[0046] Regarding the size setting of the anti-slip baffle 2221 and the size setting of the hook head of the connecting hook 222, it is only necessary to enable the hook head of the connecting hook 22 and the anti-slip baffle 2221 to pass through the two connecting holes 8 together.

[0047] When the crane lifts and moves the steel cage 1, the upper edges of the two connecting holes 8 will abut and support the inner side of the connecting hook 222. If the connecting plate 2121 slides toward the hook head of the connecting hook 222, the anti-slip baffle 2221 provided at the hook head of the connecting hook 222 and protruding toward the middle of the inner cavity of the connecting hook 222 can prevent the connecting plate 2121 from sliding out of the connecting hook 222. The anti-slip baffle 2221 can reduce the possibility of the connecting plate 2121 falling off the connecting hook 222.

[0048] In this embodiment, the steel cage lifting device for bridge bored pile construction described in the utility model also includes a supporting mechanism 9, which is arranged below the bearing plate 3; the supporting mechanism 9 includes an electric push rod 91 and a pressure plate 92, and the electric push rod 91 can be an electric push rod with model XYDHA12, one end of the electric push rod 91 is fixedly connected to the lower surface of the bearing plate 3, the output shaft of the electric push rod 91 faces downward, the upper surface of the pressure plate 92 is fixedly connected to the output shaft of the electric push rod 91, and the lower surface of the pressure plate 92 is used to support the end of the main reinforcement 101 of the steel cage 1.

[0049] When the crane lifts the steel cage 1, the electric push rod 91 is started, and the output end of the electric push rod 91 pushes the pressing plate 92 downward, so that the lower surface of the pressing plate 92 abuts against the end of the main reinforcement 101 of the steel cage 1 and pushes the steel cage 1 downward, so that a large friction force is formed between the end of the main reinforcement 101 and the pressing plate 92, thereby making it difficult for the steel cage 1 to move horizontally upward relative to the bearing plate 3, that is, it can reduce the possibility of the steel cage 1 swinging relative to the bearing plate 3. With this structure, the possibility of the steel cage 1 tilting relative to the bearing plate 3 can be reduced, and when the crane lifts the steel cage 1, it can make the steel cage 1 less likely to tilt.

[0050] Embodiment 2

[0051] See also Figure 6 - Fig.10 , Embodiment 2 is only a preferred embodiment of Embodiment 1, and the implementation of Embodiment 2 will not affect the independent implementation of Embodiment 1.

[0052] The difference between this embodiment and the first embodiment is that the structure of the abutting assembly is different, and the rest of the parts are the same as the first embodiment.

[0053] Specifically: the abutting assembly 211 includes a first abutting plate 2111 and a second abutting plate 2112, the lower end of the first abutting plate 2111 and the upper end of the second abutting plate 2112 are hinged via a transverse hinge shaft 7, the outer side surface of the lower end of the first abutting plate 2111 is recessed inwards to form a first groove 51 arranged transversely, the outer side surface of the upper end of the second abutting plate 2112 is recessed inwards to form a second groove 52 arranged transversely, the first groove 51 and the second groove 52 constitute the first accommodating groove 5, the outer side surface of the first abutting plate 2111 is recessed inwards to form a third groove 61 arranged vertically, the outer side surface of the second abutting plate 2112 is recessed inwards to form a fourth groove 62 arranged vertically, the third groove 61 and the fourth groove 62 constitute the second accommodating groove 6;

[0054] The abutting assembly 211 further includes a collar 213 , which is used to be sleeved on the main rib 101 . The collar 213 is fixedly disposed at a position of the upper end of the first abutting plate 2111 corresponding to the third groove 61 .

[0055] When installing the fixing portion 21 on the steel cage 1, the ring 213 is first sleeved on the main reinforcement 101, and the second supporting plate 2112 is rotated toward the inner side of the stiffening reinforcement 102 with the hinge shaft 7 as the axis, so that when the fixing portion 21 is moved toward the direction close to the stiffening reinforcement 102, the connecting component 212 will not be blocked by the stiffening reinforcement 102. When the fixing portion 21 moves toward the direction approaching the stiffening rib 102 and makes the first groove 51 abut against the inner side surface of the stiffening rib 102, the second abutting plate 2112 is rotated toward the outer side surface of the stiffening rib 102 with the hinge shaft 7 as the axis, so that the second groove 52 abuts against the inner side surface of the stiffening rib 102, and the fourth groove 62 abuts against the main rib 101. The first abutting plate 2111 and the second abutting plate 2112 can be detachably connected to the connection between the stiffening rib 102 and the main rib 101, the abutting assembly 211, the connecting assembly 212 and the ring 213 can be detachably connected to the connection between the stiffening rib 102 and the main rib 101, and the fixing portion 21 can be detachably connected to the connection between the stiffening rib 102 and the main rib 101. With this structure, the abutting assembly 211 is connected to the connection between the reinforcing bar 102 and the main bar 101 through the first receiving groove 5 and the second receiving groove 6. When the crane lifts the steel cage 1, the connecting portion 22 pulls the first abutting plate 2111 and the second abutting plate 2112 toward the outer side of the reinforcing bar 102. Since the collar 213 is provided at the upper end of the first abutting plate 2111 and sleeved on the main bar 101, when the first abutting plate 2111 and the second abutting plate 2112 are subjected to the pulling force of the connecting portion 22 toward the outer side of the reinforcing bar 102, the collar 213 can make the first abutting plate 2111 and the second abutting plate 2112 always abut against the inner side of the reinforcing bar 102 and the main bar 101. When the crane lifts the steel cage 1, the steel cage 1 is less likely to tilt, and it is easier to put the steel cage 1 vertically into the pile hole.

[0056] After the steel cage 1 is placed in the pile hole, the lower end of the connecting portion 22 is separated from the outer end of the connecting assembly 212, and then the second abutting plate 2112 is rotated toward the outer side of the stiffening bar 102 with the hinge shaft 7 as the axis, so that the second abutting plate 2112 is separated from the stiffening bar 102 and the main bar 101, and the ring 213 and the first abutting plate 2111 are pulled away from the stiffening bar 102 until the ring 213 and the first abutting plate 2111 are separated from the steel cage 1, so that the abutting assembly 211, the connecting assembly 212 and the ring 213 are removed from the steel cage 1, and the fixing portion 21 can be removed from the steel cage 1.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
