Description

Technical Field

[0002] A pile-slab bridge is a statically indeterminate structure of pile-slab consolidation, consisting of a factory-fabricated bridge deck and precast pipe piles. Key components, such as precast pipe piles, are the lower members of the pile-slab bridge. During construction, the stability of the lower members of the pile-slab bridge affects the construction quality of the entire bridge, especially under soft soil foundation conditions, which can affect the stress performance and bearing capacity of the entire pile-slab bridge structure. Therefore, it is particularly important to check the verticality of the precast pipe piles during construction to prevent a decrease in bearing capacity due to tilting of the precast pipe piles.

[0003] In the prior art, when hammering prefabricated pipe piles, errors in the verticality of the prefabricated pipe piles need to be corrected in a timely manner to ensure construction quality. Construction workers usually use a handheld detection device to contact the outer wall of the prefabricated pipe pile to detect the verticality of the prefabricated pipe pile, and then read the verticality data displayed by the detection device. In addition, multiple detections are required on different sides of the prefabricated pipe pile. The accuracy of the detection depends on the operating stability of the construction workers, the detection accuracy cannot be guaranteed, and the detection process is relatively complicated.

[0004] Therefore, it is necessary to propose a device for detecting the verticality of the lower components of a pile-sheet bridge to at least partially solve the problems existing in the prior art. Utility Model Content

[0031] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments so that those skilled in the art can implement the invention with reference to the description.

[0032] It should be understood that terms such as “having”, “including” and “comprising” used herein do not preclude the existence or addition of one or more other elements or combinations thereof.

[0033] like Figure 1 As shown, the utility model provides a verticality detection device for the lower member of a pile-sheet bridge, comprising: two semi-annular mounting portions 1, at least one detection body 2 being provided on the outer side of the mounting portion 1, the ends of the two mounting portions 1 being connected by a locking portion so that the two mounting portions 1 are mounted on the outer side of the lower member;

[0034] At least two mounting grooves 3 are provided on the inner annular surface of the mounting portion 1 , abutment blocks 4 are provided in the mounting grooves 3 , elastic members 5 are provided between the abutment blocks 4 and the mounting grooves 3 , and the abutment blocks 4 slide in the radial direction of the mounting portion 1 .

[0035] Among them, the lower component is a prefabricated pipe pile, and the detection body 2 can select any detection instrument in the prior art that can detect the verticality of the prefabricated pipe pile, such as a slope ruler, etc.;

[0036] The mounting grooves 3 are evenly distributed on the inner annular surface of the mounting portion 1. The abutment blocks 4 are used to elastically abut against the side surfaces of the lower member. The abutment blocks 4 are made of hard material. The elastic member 5 provides elastic support for the abutment blocks 4, so that the forces between the mounting portion 1 and the lower member are balanced, ensuring that the axis of the mounting portion 1 is parallel to the axis of the lower member, thereby improving the detection accuracy of the detection body 2.

[0037] During installation, the two mounting parts 1 are placed on the outside of the lower member so that each abutment block 4 contacts the side of the lower member, and then the ends of the two mounting parts 1 are locked using the locking part. When locking, the lower member and the abutment block 4 are pressed tightly, and multiple elastic parts 5 are compressed at the same time to provide elastic support force for the abutment block 4.

[0038] Through the above design, by utilizing the cooperation of multiple evenly distributed abutment blocks 4 and elastic parts 5, the mounting part 1 is elastically abutted against the lower component, ensuring that the forces at various positions between the mounting part 1 and the lower component are balanced, and increasing the contact friction between the two, so that when the lower component is subjected to hammering force during construction, the position of the mounting part 1 can be ensured not to shift, thereby improving the stability of the installation position of the detection body 2 and further improving the detection accuracy of the detection body 2; and, at least two detection bodies 2 are provided on the two mounting parts 1, which can perform verticality detection on multiple positions at the same time, thereby improving the convenience of detection.

[0039] like Figure 2 and Figure 3 As shown, in one embodiment, the mounting groove 3 is trapezoidal, and the opening size of the mounting groove 3 on one side facing the center of the mounting portion 1 is smaller than the opening size on the other side thereof;

[0040] Of the two ends of the mounting groove 3 extending in the width direction of the mounting portion 1 , one end is open and the other end is closed.

[0041] Furthermore, the abutment block 4 is trapezoidal, with the side close to the center of the mounting portion 1 extending out of the mounting groove 3 , and the side away from the center of the mounting portion 1 contacting the elastic member 5 .

[0042] Among them, the abutment block 4 is movably arranged in the mounting groove 3. During installation, the elastic member 5 is first installed in the mounting groove 3, and then the abutment block 4 is inserted from the opening at the top of the mounting groove 3. The side of the abutment block 4 away from the center of the mounting portion 1 contacts the elastic member 5, and the other side extends out of the mounting groove 3. After the installation is completed, under the abutting action of the elastic member 5, the two inclined surfaces of the abutment block 4 contact the two inclined surfaces of the mounting groove 3. Since the bottom end of the mounting groove 3 is closed, the bottom of the abutment block 4 contacts the mounting groove 3, which can provide a limiting effect for the abutment block 4. After the abutment block 4 is installed in place, the distance between the top of the abutment block 4 and the top of the mounting portion 1 is equal to the distance between the bottom of the abutment block 4 and the bottom of the mounting portion 1, so that the mounting portion 1 is subjected to balanced force in its width direction.

[0043] The abutment block 4 can be disassembled, so that the abutment block 4 can be easily replaced when there is a lot of wear on the abutment block 4. The abutment blocks 4 of different sizes can also be replaced according to the different diameters of the lower component. The different sizes mainly refer to the different thicknesses of the abutment block 4 in the radial direction of the mounting part 1.

[0044] like Figure 3 As shown, further, the side of the abutting block 4 close to the center of the mounting portion 1 is an arc-shaped surface.

[0045] The arcuate surface corresponds to the outer side surface of the lower component, which can increase the contact area between the abutting block 4 and the lower component and improve the contact friction.

[0046] like Figure 3 and Figure 4 As shown, in one embodiment, the elastic member 5 includes two elastic bodies 510;

[0047] Each elastic body 510 includes: a mounting piece 511 , a bending piece 512 and an abutting piece 513 connected in sequence. The mounting piece 511 is connected to the side of the mounting groove 3 away from the center of the mounting portion 1 , and the abutting piece 513 is in contact with the abutting block 4 .

[0048] The elastic body 510 is connected to the mounting slot 3 via the mounting piece 511. The two can be connected by screws, clamping or bonding.

[0049] The mounting piece 511 is arranged parallel to the abutting piece 513. After the abutting block 4 contacts the lower component and is subjected to force, it moves to the side away from the center of the mounting portion 1, pushing the abutting piece 513, thereby compressing the bent piece 512. The compression of the bent piece 512 provides elastic support for the abutting piece 513, thereby making the abutting block 4 and the lower component elastically abut.

[0050] The two elastic bodies 510 are extended in the width direction of the mounting portion 1 , and an opening is formed between the mounting piece 511 and the abutment piece 513 of the elastic body 510 . The openings of the two elastic bodies 510 are arranged relative to or oppositely to provide uniform supporting force for the abutment block 4 .

[0051] like Figure 5 As shown, in one embodiment, a first fixing block 110 and a second fixing block 120 are respectively provided at both ends of the mounting portion 1;

[0052] The locking portion includes: a first locking member 6 provided on the first fixing block 110 and a second locking member 7 provided on the second fixing block 120 , and the first locking member 6 on one mounting portion 1 is connected to the second locking member 7 on the other mounting portion 1 .

[0053] The first fixing block 110 and the second fixing block 120 are both extended toward the outer ring side of the mounting portion 1 .

[0054] Furthermore, the first locking member 6 includes: a ring 610 sleeved on the first fixed block 110, a limiting groove 111 corresponding to the ring 610 is provided on the first fixed block 110, a limiting rod 620 is provided on the side of the ring 610 away from the first fixed block 110, a connecting tube 630 is sleeved on the outer side of the limiting rod 620, an internal thread is provided in the connecting tube 630, and a pull rod 640 is provided on the outer side of the connecting tube 630.

[0055] The first fixing block 110 has an arc-shaped surface close to the outer ring side of the mounting portion 1. The limiting groove 111 is provided on the arc-shaped surface. The collar 610 is sleeved from the outer side of the first fixing block 110 into the limiting groove 111.

[0056] The connecting tube 630 can slide along the axial direction of the limiting rod 620, and the connecting tube 630 and the limiting rod 620 can rotate relative to each other. A limiting ring is provided at the end of the limiting rod 620 away from the ring 610 to limit the axial sliding of the limiting rod 620 and the connecting tube 630.

[0057] Furthermore, the second locking member 7 includes a screw 710 provided on the second fixing block 120 , and the screw 710 is threadedly connected to the connecting cylinder 630 .

[0058] When the two mounting parts 1 are locked, the ring 610 of the first locking member 6 is sleeved in the limiting groove 111 of the first fixing block 110, connecting the connecting tube 630 with the screw 710, and the connecting tube 630 is rotated by driving the lever 640, so that the connecting tube 630 and the screw 710 are threadedly connected; when the first locking member 6 and the second locking member 7 are locked and fixed, no other tools are required to achieve fixed locking, and it is easy to use.

[0059] like Figure 6 and Figure 7 As shown, in one embodiment, a slot 121 is provided on the second fixed block 120, a rotating rod 122 is rotatably provided in the slot 121, the screw 710 is provided on the rotating rod 122, and the axis of the screw 710 is perpendicular to the axis of the rotating rod 122, and the axis of the rotating rod 122 is parallel to the axis of the mounting portion 1.

[0060] The screw 710 is configured to be rotatable. Since the collar 610 is movably disposed in the limiting groove 111, and the limiting groove 111 is arranged parallel to the axis of the mounting portion 1, the connecting cylinder 630 can rotate about the portion of the collar 610 in the limiting groove 111 as the rotation axis, and the screw 710 can rotate along the axis of the rotating rod 122.

[0061] Therefore, during installation, the positions of the connecting tube 630 and the screw rod 710 can be adjusted, so as to ensure that the axes of the connecting tube 630 and the screw rod 710 are collinear, thereby facilitating the threaded connection between the two.

[0062] In one embodiment, the locking portion may also be a bolt, and threaded holes are provided on the first fixing block 110 and the second fixing block 120 , and the two mounting portions 1 are locked and fixed by the bolts.

[0063] like Figure 2 and Figure 5 As shown, in one embodiment, a receiving groove 8 is provided on the inner annular surface of the mounting portion 1, a mounting block 9 is provided at a position corresponding to the receiving groove 8 on the outer annular surface of the mounting portion 1, a mounting plate 10 is provided on the mounting block 9, and the detection body 2 is arranged on the mounting plate 10.

[0064] The mounting block 9 is integrally provided with the mounting portion 1. A first threaded hole is provided in the receiving groove 8 and passes through the mounting block 9. A stepped hole corresponding to the first threaded hole is provided on the mounting plate 10. During installation, a screw can be inserted through the stepped hole of the mounting plate 10 and threadedly connected to the mounting block 9. Alternatively, a through hole is provided in the receiving groove 8 and passes through the mounting block 9. During installation, a bolt is inserted through the stepped hole of the mounting plate 10 and passes through the mounting block 9. The end of the bolt extending into the receiving groove 8 is fixed by a nut, and the bolt does not protrude from the receiving groove 8.

[0065] Four second threaded holes can be set on the mounting plate 10 for installing and fixing the shell of the detection body 2. For example, when the detection body 2 uses a slope ruler, a shell corresponding to the slope ruler can be set to support the slope ruler, and then the shell and the second threaded holes are fixed with screws.

[0066] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation to the present invention.

[0067] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection, or communication; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified.
