Description

Technical Field

[0001] This application relates to the field of construction machinery technology, specifically to a highway bridge foundation pile reinforcement device for municipal engineering that is easy to assemble and disassemble. Background Technology

[0002] Pile foundations are a type of deep foundation used when the shallow soil is too weak to withstand the load of the superstructure. They transfer the load through the piles to deeper, harder soil or rock layers. The main functions of pile foundations include load transfer, reducing settlement, and improving soil density. However, pile foundations inevitably suffer damage and even instability over long-term use. Therefore, pile foundation reinforcement devices are needed. However, existing pile foundation reinforcement devices are complex in structure and difficult to install; a reinforcement device that is easy to transport and disassemble is required. Utility Model Content

[0003] A highway bridge foundation pile reinforcement device for municipal engineering that is easy to assemble and disassemble includes three articulated arm assemblies arranged in a circumferential direction. The articulated arm assembly includes an arc-shaped upper hoop, an articulated connecting rod, and a fixed lower plate.

[0004] The arc-shaped upper hoop includes an arc-shaped hoop body with an arc of 2π / 3. The upper right side of the arc-shaped hoop body has an upper end cutout, and a hinge mandrel is provided at the upper end cutout. The upper left side of the arc-shaped hoop body has an end arm, and a hinge insertion hole is provided on the end arm. The outer arc surface of the arc-shaped hoop body has a hoop upper insertion lug that is hinged to the hinge connecting rod.

[0005] The hinged connecting rods correspond one-to-one with the arc-shaped upper hoop, and the upper end of the hinged connecting rods is hinged to the arc-shaped upper hoop;

[0006] The fixed lower plate corresponds one-to-one with the hinged connecting rod, and the fixed lower plate is hinged to the lower end of the hinged connecting rod.

[0007] As a further technical solution:

[0008] Each hinged spindle is equipped with an automatic check device, which includes a check chamber, a check swing arm, and a reset spring.

[0009] The check chamber includes a check cavity located at the upper end of the hinged spindle, and a spring spindle located in the upper half of the check cavity along the left-right direction. The check cavity has a side-mounted through hole on the left and right sides, and a swing arm spindle on the left and right sides of the inner wall of the check cavity.

[0010] The anti-return swing arm is provided in a pair. The anti-return swing arm includes a swing arm body that is rotatably provided on the swing arm spindle, a lower stop block provided on the outer side of the lower end of the swing arm body, and a receiving groove formed on the swing arm body and accommodating the spring spindle.

[0011] A reset spring is wound around the spring spindle and is located between a pair of swing arm bodies.

[0012] Thanks to the improved technical solution described above, the hinged mandrel can be prevented from coming out after being inserted into the hinged socket:

[0013] The hinged spindle drives the automatic check valve to insert into the hinged socket. The inner wall of the hinged socket presses against the check valve arm, causing it to retract against the damping of the reset spring, until the lower end of the check valve arm passes the upper edge of the hinged socket and then pops outward.

[0014] The automatic check valve also includes a foolproof component, which includes a through screw hole at the lower end of the check valve cavity and an external threaded rod screwed into the through screw hole; furthermore, the upper end of the external threaded rod is provided with a tapered head that is narrower at the top and wider at the bottom.

[0015] The technical solution of this utility model has the following beneficial effects:

[0016] The reinforcement device is formed by connecting three articulated arm assemblies, and the three articulated arm assemblies have completely identical structures, which facilitates mass production; the split articulated arm assemblies reduce space occupation and facilitate transportation.

[0017] The reinforcement device is easy to assemble and disassemble. In particular, the three arc-shaped upper hoops can be fixed by simply inserting the hinged mandrel and the hinged insertion hole. Moreover, the above-mentioned insertion fixation has a locking effect and will not loosen after insertion. Attached Figure Description

[0036] A highway bridge foundation pile reinforcement device for municipal engineering that is easy to assemble and disassemble includes three articulated arm assemblies 9 arranged in a circumferential direction. The articulated arm assembly 9 includes an arc-shaped upper hoop 1, an articulated connecting rod 2, and a fixed lower plate 3.

[0037] The arc-shaped upper hoop 1 includes an arc-shaped hoop body 11 with an arc of 2π / 3. The upper right side of the arc-shaped hoop body 11 has an upper end cutout 12, and a hinge mandrel 13 is provided at the upper end cutout 12. The upper left side of the arc-shaped hoop body 11 has an end arm 14, and a hinge insertion hole 15 is provided on the end arm 14. The outer arc surface of the arc-shaped hoop body 11 has a hoop upper insertion lug 16 that is hinged to the hinge connecting rod 2.

[0038] The hinged connecting rod 2 corresponds one-to-one with the arc-shaped upper hoop 1, and the upper end of the hinged connecting rod 2 is hinged to the arc-shaped upper hoop 1;

[0039] The fixed lower plate 3 corresponds one-to-one with the hinged connecting rod 2, and the fixed lower plate 3 is hinged to the lower end of the hinged connecting rod 2.

[0040] As a further technical solution:

[0041] Each hinged spindle 13 is equipped with an automatic check device 4, which includes a check chamber 41, a check swing arm 42, and a reset spring 43.

[0042] The check chamber 41 includes a check inner cavity 411 located at the upper end of the hinge spindle 13, and a spring spindle 412 located in the upper half of the check inner cavity 411 along the left and right directions. The check inner cavity 411 is provided with a side through hole 413 on the left and right sides respectively, and a swing arm spindle 414 is provided on the left and right sides of the inner wall of the check inner cavity 411.

[0043] The anti-return swing arm 42 is provided in a pair. The anti-return swing arm 42 includes a swing arm body 421 rotatably provided on the swing arm spindle 414, a lower stop block 422 provided on the outer side of the lower end of the swing arm body 421, and a receiving groove 423 formed on the swing arm body 421 and accommodating the spring spindle 412.

[0044] A reset spring 43 is wound around the spring spindle 412 and is located between a pair of swing arm bodies 421.

[0045] Thanks to the improved technical solution described above, the hinged mandrel 13 can be prevented from coming out after being inserted into the hinged socket 15.

[0046] The hinged spindle 13 drives the automatic check valve 4 to be inserted into the hinged socket 15. The inner wall of the hinged socket 15 presses the check arm 42 to overcome the damping of the reset spring 43 and retract until the lower end of the check arm 42 passes the upper edge of the hinged socket 15 and then pops outward.

[0047] The automatic check valve 4 also includes a foolproof component 44, which includes a through screw hole 441 at the lower end of the check cavity 411 and an external threaded rod 442 screwed into the through screw hole 441; furthermore, the upper end of the external threaded rod 442 is provided with a tapered head 443 that is narrow at the top and wide at the bottom.

[0048] Thanks to the improved technical solution described above, the anti-foolproof component 44 can be rotated to insert between a pair of anti-return arms 42, thus preventing the anti-return effect from failing when the reset spring 43 fails and the anti-return arms 42 retract.

[0049] The reinforcement device in this case is installed as follows:

[0050] The three articulated arm assemblies 9 are arranged around the pile foundation, and the articulated mandrel 13 of the arc-shaped upper hoop 1 is inserted into the articulated insertion hole 15 of the arc-shaped upper hoop 1 in sequence, so that the three arc-shaped upper hoop 1 form a complete circle, and the pile foundation is initially clamped and fixed.

[0051] Adjust the vertical position of the arc-shaped upper hoop 1 to adjust the tilt angle of the hinged connecting rod 2, and then connect and fix the lower plate 3 to the ground foundation.

[0052] It should be noted that the upper end face of the arc-shaped hoop 11 is provided with an upper protrusion 17 at the center, and the upper protrusion 17 is provided with a clamping screw hole 17. The pile foundation inside the arc-shaped upper hoop 1 is completely fixed by installing bolts or other means on the clamping screw hole 17.
