Description

Technical Field

[0001] This utility model relates to the field of drainage pipe installation, and in particular to an anti-slip drainage pipe fixing clamp for foundation pit dewatering. Background Technology

[0002] In foundation pit dewatering projects, loosely fixed drainage pipes can easily lead to pipe displacement, loose joints, or system failure. Traditional pipe clamps often use bolt fastening or simple clamp structures, which are difficult to adapt to the dual effects of pipe vibration and soil deformation in wet and muddy environments, and are prone to slippage. Existing clamps lack effective pull-out resistance mechanisms, and the single-point anchoring force is insufficient. When pipelines are laid out in a disorderly manner, interference between cables and water pipes can easily cause safety hazards. The installation efficiency is low and it is also difficult to meet the stability requirements of dynamic dewatering conditions.

[0003] Therefore, in order to address the above problems, a non-slip drainage pipe fixing clamp for foundation pit dewatering is now being developed. Utility Model Content

[0004] In order to overcome the shortcomings of existing clamps, such as lack of effective pull-out resistance mechanism, insufficient single-point anchoring force, easy interference between cables and water pipes when pipelines are laid out in a messy manner, low installation efficiency and difficulty in meeting the stability requirements of dynamic dewatering conditions, this utility model provides an anti-slip drainage pipe fixing clamp for foundation pit dewatering.

[0005] The technical solution of this utility model is: a fixing clamp for anti-slip drainage pipes used for foundation pit dewatering, comprising a mounting frame, a first arc-shaped component rotatably connected to the mounting frame, a rotating shaft rotatably connected to the middle of the mounting frame, a second arc-shaped component connected to the rotating shaft, gears being provided on the front side of the mounting frame and the front side of the rotating shaft, the two gears meshing with each other, a pulley assembly being provided between the rear side of the rotating shaft and the first arc-shaped component, two first inserts being slidably connected to the mounting frame, a first pin being slidably connected between the first inserts and the mounting frame, a mounting component being provided on the outside of the mounting component, a connecting rope being installed on the mounting component, a second insert being installed on the connecting rope, a push rod being slidably connected to the second insert, an elastic plate being provided inside the second insert, the elastic plate being able to be pushed outward by the push rod.

[0006] More preferably, the upper gear is provided with an assistive turning handle.

[0007] More preferably, the pulley assembly consists of a pulley and a belt.

[0008] More preferably, both the first plug-in and the second plug-in have a tapered bottom structure.

[0009] More preferably, a limit block is provided at the top of the push rod.

[0010] More preferably, both the first arc-shaped member and the second arc-shaped member are provided with wire-clamping members on their outer sides. The wire-clamping members are used to bundle and guide cables or wires, and a second pin is provided between adjacent wire-clamping members.

[0011] By adopting the above technical solution, compared with the prior art, this utility model has the following advantages: This invention utilizes the linkage of gears and pulleys to achieve precise synchronous closure of the double arc-shaped components, adaptively clamping different pipe diameters. The self-locking anchoring mechanism triggered by the elastic plate significantly enhances the pull-out resistance, while the plug-in tapered guide and double pin locking ensure stable and convenient installation.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] A type of anti-slip drainage pipe fixing clamp for foundation pit dewatering, such as Figures 1-4As shown, the device includes a mounting bracket 1, a first arc-shaped component 2 rotatably connected to the mounting bracket 1, a rotating shaft 4 rotatably connected to the middle of the mounting bracket 1, a second arc-shaped component 3 connected to the rotating shaft 4, gears 5 being provided on the front side of both the mounting bracket 1 and the front side of the rotating shaft 4, the two gears 5 meshing with each other, an assistive wrench being provided on the upper gear 5, a pulley assembly 6 being provided between the rear side of the rotating shaft 4 and the first arc-shaped component 2, the pulley assembly 6 consisting of a pulley and a belt, two first inserts 7 being slidably connected to the mounting bracket 1, and a first pin 8 being slidably connected between the first inserts 7 and the mounting bracket 1, and a... There is an installation component 9, on which a connecting rope 10 is installed. A second plug 11 is installed on the connecting rope 10. The bottom of both the first plug 7 and the second plug 11 is tapered. A push rod 12 is slidably connected to the second plug 11. A limit block is provided at the top of the push rod 12. An elastic piece 13 is provided inside the second plug 11. The elastic piece 13 can be pushed outward by the push rod 12. A wire clamping component 14 is provided on the outside of both the first arc-shaped component 2 and the second arc-shaped component 3. The wire clamping component 14 is used to bundle and guide cables or wires. A second pin 15 is provided between adjacent wire clamping components 14.

[0019] It should be noted that during operation, the mounting bracket 1 is first placed against the side wall of the pit or the support structure. The upper gear 5 is rotated manually by turning the power lever. Due to the transmission action of the two meshing gears 5, the rotating shaft 4 rotates synchronously in opposite directions, causing the second arc-shaped component 3 fixed on it to rotate inward. At the same time, the rear side of the rotating shaft 4 is linked to the first arc-shaped component 2 through the pulley assembly 6, so that the two sets of arc-shaped components can achieve precise synchronous opposite movement. The first arc-shaped component 2 retracts inward, and the second arc-shaped component 3 closes inward, thereby adaptively wrapping the outer wall of the drainage pipe with different diameters, forming a uniform ring constraint force. During the closing process of the double arc-shaped components, their inner arc surfaces are tightly attached to the pipe wall, and the axial sliding of the pipe is initially suppressed by friction. Then, the plug-in is fixed. The operator holds the connecting rope 10 on the outside of the mounting component 9, aligns the bottom conical tip of the first plug-in 7 and the second plug-in 11 with the preset positioning hole of the pit soil or soft rock layer, and manually pushes the limiting block at the top of the rod 12, so that it slides axially inside the second plug-in 11. The front end of the push rod 12 presses against the elastic plate 13. After being subjected to force, the elastic plate 13 undergoes elastic deformation, and its end is forced to turn outward radially, like a barb, firmly stuck into the soil or rock crevices of the hole wall, forming a strong mechanical self-locking pull-out force. At this time, the connecting rope 10 is continuously taut, and the synergistic pulling force makes the second plug 11 and the first plug 7 in a tension anchored state. At the same time, the first plug 7 is locked in the groove depth position of the mounting frame 1 by the first pin 8, ensuring that the entire set of clamps is tightly attached to the pit surface without displacement. If it is necessary to resist lateral shear force, the first pin 8 can be pulled out to adjust the horizontal embedding depth of the first plug 7 until the cone head is completely submerged in the geological body. When cables need to be laid near the drainage pipe, the wire clamping parts 14 preset on the outside of the first arc-shaped part 2 and the second arc-shaped part 3 can be used flexibly. The movable buckle on the wire clamping part 14 can be moved to embed the cable into its arc-shaped groove. Then, the second pin 15 is inserted through the reserved hole of the adjacent wire clamping part 14 to realize the rapid bundling and guidance of multiple cables, avoiding the tangling of pipelines.

Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
