Description

Technical Field

[0001] The utility model relates to an installation device for a water conservancy cofferdam water stop board, belonging to the technical field of water conservancy cofferdam construction. Background Art

[0002] The water conservancy cofferdam water stop board is an important device for building a temporary enclosure structure in water conservancy project construction. Its main function is to isolate all or part of the building foundation pit from the riverbed so as to carry out construction in a waterless environment.

[0003] During actual construction, multiple water stop boards are usually spliced together to meet the area and depth requirements of cofferdam construction. In order to reduce the gaps between the spliced water stop boards, a cylindrical water stop board formed integrally is mostly used at present. However, when hoisting and splicing the cylindrical water stop board, due to the unclear reference object, in order to ensure the coaxiality between the cylindrical water stop board and the base, as well as between multiple cylindrical water stop boards, it is often necessary to manually adjust its position frequently to meet the splicing requirements. This results in a cumbersome installation process of the water stop board, and both the installation efficiency and accuracy are relatively low. Summary of the Invention

Detailed implementation manners

[0041] The present utility model will be described in detail below in conjunction with embodiments, but the present utility model is not limited to these embodiments.

[0042] An installation device for a water conservancy cofferdam water baffle is provided in an embodiment of the present utility model. As Figure 1 shown, the device includes:

[0043] Base 1;

[0044] A plurality of positioning posts 6, all arranged on the base 1, for limiting the water baffle 4; the bottom of the positioning post 6 has a threaded hole;

[0045] A plurality of connecting bolts 8, threadedly connected to the base 1 and corresponding to the plurality of positioning posts 6 one by one; the connecting bolt 8 is matched with the threaded hole of the corresponding positioning post 6;

[0046] A transmission assembly, connected to all the plurality of connecting bolts 8, for driving the plurality of connecting bolts 8 to rotate so that the top of each connecting bolt 8 is screwed into the threaded hole of the corresponding positioning post 6 respectively.

[0047] By providing a plurality of positioning posts 6 on the base 1, the present utility model can provide a positioning reference for the installation of the water baffle 4, facilitating the efficient and accurate installation of the water baffle 4.

[0048] In this embodiment, the base 1 is fixed to the ground through a plurality of fixing members 2, and the fixing members 2 can be long screws. The base 1 is cylindrical in shape and is provided with two positioning posts 6; the water baffle 4 is cylindrical in shape and is provided with two positioning holes; the two positioning holes correspond to and match the two positioning posts 6 one by one. During installation, only by passing each positioning hole of the water baffle 4 through the corresponding positioning post 6 can the coaxiality between the water baffle 4 and the base 1 be ensured. At the same time, when stacking and splicing a plurality of water baffles 4, the positioning posts 6 can also be used as a positioning reference to ensure the coaxiality between the plurality of water baffles 4, thereby simplifying the installation process and improving the installation efficiency and installation accuracy.

[0049] Specifically, a first lifting lug 5 is provided at the top end of the water baffle 4, and a second lifting lug 7 is provided at the top end of the positioning post 6, facilitating the hoisting operation of the water baffle 4 and the positioning post 6 during the installation process.

[0050] By providing the connecting bolts 8 and the transmission assembly, the utility model can drive the connecting bolts 8 to screw into or out of the positioning posts 6 by means of the transmission assembly, so as to realize the rapid installation or disassembly of the positioning posts 6, thereby further improving the installation efficiency.

[0051] Specifically, as Figure 1 and Figure 2 shown, the two positioning posts 6 of this embodiment are respectively arranged at the two ends of the diameter of the cylindrical base 1. Two nuts 3 are respectively fixed at the positions of the base 1 opposite to the two positioning posts 6, and the two connecting bolts 8 are respectively threadedly connected in the two nuts 3. The transmission assembly can drive the connecting bolts 8 to rotate forward or backward, so that the connecting bolts 8 are screwed into or out of the nuts 3, thereby realizing that the connecting bolts 8 are screwed into the screw holes of the positioning posts 6 from the base 1 or withdrawn from the screw holes of the positioning posts 6.

[0052] Specifically, the transmission assembly can include a gear transmission mechanism, can also include a worm and worm gear transmission mechanism, and can also include other transmission mechanisms.

[0053] Specifically, as Figure 2 and Figure 4 shown, the transmission assembly can include:

[0054] A plurality of driven gears 9, corresponding to the plurality of connecting bolts 8 one by one; the driven gears 9 are connected to the corresponding connecting bolts 8 and are used to drive the corresponding connecting bolts 8 to rotate;

[0055] A driving gear 10, meshing with all the plurality of driven gears 9, and is used to drive the plurality of driven gears 9 to rotate.

[0056] Specifically, this embodiment is provided with two identical driven gears 9. The two driven gears 9 are respectively located below the two connecting bolts 8. The driving gear 10 is coaxially arranged with the cylindrical base 1 and meshes with the two driven gears 9. When the driving gear 10 rotates, it can drive the two driven gears 9 to rotate simultaneously, thereby driving the two connecting bolts 8 to rotate.

[0057] Specifically, the driven gear 9 is arranged below the corresponding connecting bolt 8; the transmission assembly can also include:

[0058] A plurality of transmission rods 11, corresponding to the plurality of driven gears 9 one by one; the transmission rods 11 are coaxially arranged with the corresponding driven gears 9 and the corresponding connecting bolts 8. The top ends thereof are slidably penetrated in the corresponding connecting bolts 8, and the bottom ends thereof are fixedly connected to the corresponding driven gears 9; the driven gears 9 drive the corresponding connecting bolts 8 to rotate through the corresponding transmission rods 11.

[0059] Specifically, the interior of the connecting bolt 8 has a limiting cavity extending along its axis, and the top end of the connecting rod slides through the limiting cavity. In this embodiment, the cross-sectional areas of both the limiting cavity and the top end of the connecting rod are square and match each other, so that when the connecting rod rotates, it can drive the connecting bolt 8 to rotate.

[0060] Furthermore, the bottom of the connecting bolt 8 also has a limiting hole communicating with the limiting cavity; the cross-sectional area of the limiting hole is smaller than that of the limiting cavity; as Figure 3 shown, the transmission rod 11 may include:

[0061] a rod portion 12, which is inserted through the limiting hole of the corresponding connecting bolt 8, with the top end located in the limiting cavity of the corresponding connecting bolt 8 and the bottom end fixedly connected to the corresponding driven gear 9;

[0062] a limiting block 13, fixed to the top end of the rod portion 12, and its cross-sectional area matches that of the corresponding limiting cavity.

[0063] Since the cross-sectional area of the limiting hole is smaller than that of the limiting cavity, and the cross-sectional area of the limiting cavity matches that of the limiting block 13, the cross-sectional area of the limiting block 13 must be larger than that of the limiting hole. In this way, the limiting block 13 can limit the screwing-in distance of the connecting bolt 8, thereby preventing the connecting bolt 8 from slipping off the transmission rod 11 during rotation.

[0064] Specifically, the device may further include:

[0065] a locking assembly, connected to the transmission assembly, for locking the transmission assembly to limit the multiple connecting bolts 8 screwed into the multiple positioning posts 6.

[0066] By setting the locking assembly in the present utility model, after the connecting bolt 8 is screwed into the screw hole of the positioning post 6, the transmission assembly can be stopped, thereby limiting the connecting bolt 8 to prevent the connecting bolt 8 from rotating in the reverse direction and withdrawing from the screw hole of the positioning post 6. At the same time, when it is necessary to remove the positioning post 6, the locking assembly can release the stop of the transmission assembly, thereby releasing the limit on the connecting bolt 8, so that the connecting bolt 8 can withdraw from the screw hole of the positioning post 6.

[0067] Specifically, the multiple driven gears 9 and the driving gear 10 are both horizontally arranged in the base 1; a chute 14 is provided on the base 1, penetrating through its outer wall and extending along the rotation direction of the driving gear 10; the locking assembly may include:

[0068] a sliding rod 15, slidably inserted through the chute 14, with one end fixedly connected to the driving gear 10;

[0069] a limiting unit, connected to the end of the sliding rod 15 away from the driving gear 10, for limiting the position of the sliding rod 15 in the chute 14.

[0070] In this embodiment, as Figure 5 shown, the sliding groove 14 penetrates the upper surface of the base 1, and its shape is an arc coaxial with the cylindrical base 1; the sliding rod 15 is vertically arranged in the sliding groove 14, and the bottom end is fixedly connected to the driving gear 10.

[0071] Specifically, the limiting unit may include:

[0072] A connecting piece 16, arranged outside the base 1, one end is connected to the end of the sliding rod 15 away from the driving gear 10, and the other end has a through screw hole;

[0073] A screw 17, threadedly connected in the screw hole of the connecting piece 16, and one end abuts against the surface of the base 1.

[0074] By rotating the screw 17 to make it abut against the base 1, the stopping of the driving gear 10 can be realized.

[0075] In this embodiment, the connecting piece 16 is L-shaped, and the surface opposite to the side wall of the base 1 is provided with a through screw hole.

[0076] Further, a handle 20 is further provided on the surface of the screw 17 away from the base 1, which is convenient for rotating the screw 17.

[0077] Specifically, the limiting unit may further include:

[0078] A stopping block 18, clamped between the screw 17 and the base 1.

[0079] In order to increase the contact area and static friction force when the stopping block 18 abuts against the base 1, the stopping block 18 can be made of a material with certain elasticity.

[0080] Further, a friction plate 21 is provided on the surface of the base 1 that abuts against the stopping block 18, which can further increase the static friction force.

[0081] In this embodiment, the surface of the base 1 that abuts against the stopping block 18 is an arc surface, and the surface of the stopping block 18 facing the base 1 has an arc abutting surface matching the arc surface; the limiting unit may further include:

[0082] A limiting rod 19, arranged between the base 1 and the connecting piece 16 along the axial direction of the screw 17, and one end is fixedly connected to the connecting piece 16; the stopping block 18 is slidably arranged on the limiting rod 19; the limiting rod 19 is used to limit the rotation of the stopping block 18.

[0083] By setting the limiting rod 19, it can be ensured that during the process of the screw rod 17 pushing the stop block 18 towards the base 1, the stop block 18 does not rotate, so that the arc-shaped contact surface of the stop block 18 can be directly opposite to the arc-shaped surface of the base 1 during contact, achieving the effect of increasing the static friction force between the stop block 18 and the base 1.

[0084] In this embodiment, the limiting rod 19 is cylindrical in shape and is located above the screw rod 17. Its length is less than the distance between the connecting piece 16 and the base 1. The stop block 18 is sleeved on the limiting rod 19. Due to the action of gravity, the stop block 18 will not rotate during the movement towards the base 1. In practice, the shape of the limiting rod 19 can also be set as triangular, square or other shapes. In this way, the limiting rod 19 can be set at any azimuth in the circumferential direction of the screw rod 17. As long as a through hole matching the shape of the limiting rod 19 is opened at the corresponding position of the stop block 18, the stop block 18 can be slidably sleeved on the limiting rod 19 to prevent the stop block 18 from rotating.

[0085] The above are only several embodiments of the present application, and do not impose any form of limitation on the present application. Although the present application is disclosed above with preferred embodiments, it is not intended to limit the present application. Any person skilled in the art, without departing from the scope of the technical solution of the present application, making some changes or modifications using the technical content disclosed above is equivalent to equivalent implementation cases and all belong to the scope of the technical solution.
