Description

A fastening device for water conservancy and hydropower construction Technical Field

[0001] This utility model relates to the field of fastening technology in water conservancy and hydropower construction, and in particular to a fastening device for water conservancy and hydropower construction. Background Technology

[0002] Water conservancy and hydropower construction fastening devices are specialized equipment used in water conservancy and hydropower engineering construction for temporary or permanent fixing of components such as pipes, formwork, and steel structures, aiming to improve construction stability, safety, and efficiency.

[0003] According to the Chinese patent "A Fastening Device for Water Conservancy and Hydropower Construction" (authorization announcement number "CN220186057U"), when the lever is released, the locking block is automatically fixed inside the locking groove under the action of the return spring, thus fastening the water conservancy and hydropower pipeline. Then, the lever is rotated and engaged with the upper part of the lock body to fix the locking lever and prevent it from sliding. This achieves the locking of the upper clamping plate onto the lower clamping plate, thereby ensuring the fastening of the water conservancy and hydropower construction pipeline.

[0004] In the aforementioned application, the vibration force generated by the liquid flowing in the pipeline is transmitted to the surface of the lever and the return spring, which can easily cause the lever to flip over, thereby causing the locking lever to disengage from the locking block, thus affecting the stable fastening of the pipeline. Summary of the Invention

[0005] Therefore, it is necessary to provide a fastening device for water conservancy and hydropower construction to address the problem of unstable pipeline fastening.

[0006] The system includes: a mounting base, with a support base slidably connected to its inner wall, and an arc-shaped seat hinged to the top of the support base; and a fastening mechanism, comprising a clamping rod and a clamping bracket slidably connected to the inner wall of the support base. The surface of the clamping rod is engaged with the inner wall of the arc-shaped seat, one end of the clamping rod is fixedly connected to a spring, and the other end of the spring is fixedly connected to the inner wall of the support base. The surface of the clamping bracket is slidably connected to the inner wall of the clamping rod, and a screw is threadedly connected to the inner wall of the clamping bracket. The surface of the screw is threadedly connected to the inner wall of the arc-shaped seat. The spring pushes the clamping rod to automatically engage within the arc-shaped seat, initially locking the arc-shaped seat onto the support base surface. The clamping bracket slides into the support base and the clamping rod, and the screw is threaded into the clamping bracket and the support base, thus ensuring the clamping rod is stably engaged within the arc-shaped seat, guaranteeing a stable and secure fastening of the pipeline.

[0007] In one embodiment, a limiting block is slidably connected to the front end of the card holder, and the surface of the limiting block is engaged with the inner wall of the screw.

[0008] In one embodiment, a blocking block is slidably connected to the front end of the clamp. The locking block and the blocking block work together to lock the screw, ensuring the screw's threaded connection remains stable within the clamp and the arc-shaped seat. This, in turn, ensures the arc-shaped seat is stably locked onto the support surface, thereby improving the stability and fastening of the pipeline.

[0009] In one embodiment, a connecting rope is fixedly connected to the front end of the barrier block, and the other end of the connecting rope is fixedly connected to the front end of the holder. The connecting rope restricts the placement of the barrier block, preventing the risk of loss.

[0010] In one embodiment, the inner wall of the support base is provided with a sliding groove.

[0011] In one embodiment, a sliding block is fixedly connected to both sides of the top of the card holder, and the surface of the sliding block is slidably connected to the inner wall of the sliding groove. The interaction between the sliding groove and the sliding block restricts the movement range of the card holder, preventing it from detaching from the support base.

[0012] In one embodiment, one end of the lever is fixedly connected to a sliding rope, and the other end of the sliding rope passes through and extends out of the inner wall of the support base.

[0013] In one embodiment, a pull plate is fixedly connected to the bottom end of the sliding rope, and both the connecting rope and the sliding rope are nylon components. Beneficial Effects

[0014] 1. By using a spring to push the clamp rod to automatically lock into the arc-shaped seat, the arc-shaped seat is initially locked onto the surface of the support seat. The clamp bracket slides into the support seat and the clamp rod, and the screw thread is installed in the clamp bracket and the support seat, thereby achieving stable clamping of the clamp rod into the arc-shaped seat. Compared with the existing fastening devices that are unstable in fastening water conservancy and hydropower construction pipelines, this method ensures that the arc-shaped seat is stably locked onto the surface of the support seat, thereby ensuring the stable fastening of the pipeline by the fastening device;

[0015] 2. By cooperating with the limit block and the blocking block, the screw is locked, thereby ensuring that the screw thread is stably within the bracket and the arc-shaped seat, and thus the arc-shaped seat is stably locked on the surface of the support seat, thereby improving the stability and fastening of the pipeline.

[0028] The following describes the hydraulic and hydropower construction fastening device of this utility model with reference to Figures 1-4.

[0029] In one embodiment, a hydraulic and hydropower construction fastening device includes: a mounting base 100, a support base 200 slidably connected to the inner wall of the mounting base 100, and an arc-shaped seat 300 hinged to the top of the support base 200; and a fastening mechanism 400, which includes a clamping rod 401 slidably connected to the inner wall of the support base 200 and a clamping bracket 403. The surface of the clamping rod 401 is clamped to the inner wall of the arc-shaped seat 300, one end of the clamping rod 401 is fixedly connected to a spring 402, the other end of the spring 402 is fixedly connected to the inner wall of the support base 200, the surface of the clamping bracket 403 is slidably connected to the inner wall of the clamping rod 401, and the inner wall of the clamping bracket 403 is threadedly connected to a screw 404, the surface of the screw 404 being threadedly connected to the inner wall of the arc-shaped seat 300.

[0030] Both spring 402 and screw 404 are made of 304 stainless steel, which has good corrosion resistance and rust prevention properties.

[0031] Mounting base 100 includes a base, a telescopic cylinder, bolts, a first reinforcing block, and a second reinforcing block. Support base 200 includes a telescopic rod and a support. The bottom end of the telescopic cylinder is fixedly connected to the top end of the base. The top end of the base has annularly distributed pre-drilled holes. The bottom of the first reinforcing block is fixedly connected to the top end of the base, and one side of the first reinforcing block is fixedly connected to the surface of the telescopic cylinder. The bottom of the second reinforcing block is fixedly connected to the top end of the telescopic cylinder, and the surface of the second reinforcing block contacts the surface of the telescopic rod. The bolts are threaded sequentially to the inner walls of the telescopic cylinder and the telescopic rod. Evenly distributed threaded holes can be opened on the surface of the telescopic rod to facilitate adjustment of the height of the telescopic rod within the telescopic cylinder. This is a relatively common and well-known technology in the field and is not closely related to the technical problem of this application; therefore, it has not been described in detail.

[0032] In this embodiment, when it is necessary to tighten the pipeline for water conservancy and hydropower construction, after measuring the installation location of the pipeline, a long bolt is slid into the reserved hole on the mounting base 100 and threaded onto the ground using an electric wrench. After pulling the support base 200 up to a suitable height within the mounting base 100, the bolt is threaded onto the mounting base 100 and the support base 200 using an electric wrench. The pipeline is then hoisted onto the surface of the support base 200 using appropriate hoisting tools. The hoisting of the pipeline is then released, and the arc-shaped seat 300 is pulled. The pipe is flipped so that the arc-shaped surface of the arc-shaped seat 300 abuts against the pipe surface. At this time, the elastic force of the spring 402 pushes the clamp rod 401 to automatically engage with the arc-shaped seat 300, and pushes the clamp bracket 403 to move within the support base 200 and slide into the clamp rod 401. The screw rod 404 is threaded into the clamp bracket 403 and the arc-shaped seat 300, thereby securing the pipe. At this time, the construction personnel assemble the pipe in the above manner. The pipe assembly steps are existing known technology and will not be described in detail here.

[0033] As shown in Figure 3, a limiting block 405 is slidably connected to the front end of the card holder 403. The surface of the limiting block 405 is engaged with the inner wall of the screw 404. A blocking block 406 is slidably connected to the front end of the card holder 403. A connecting rope 407 is fixedly connected to the front end of the blocking block 406. The other end of the connecting rope 407 is fixedly connected to the front end of the card holder 403. A shifting groove 411 is provided on the inner wall of the support base 200. Shifting blocks 410 are fixedly connected to both sides of the top of the card holder 403. The surface of the shifting blocks 410 is slidably connected to the inner wall of the shifting groove 411.

[0034] The lever 401, the bracket 403, the limit block 405, and the blocking block 406 are all rubber components, which have good friction and elasticity.

[0035] In this embodiment, the push limit block 405 moves within the card holder 403 and engages with the screw 404, and the push block 406 slides into the card holder 403, so that one side of the block 406 contacts one side of the limit block 405.

[0036] As shown in Figure 3, one end of the lever 401 is fixedly connected to a sliding rope 408, the other end of the sliding rope 408 passes through and extends out of the inner wall of the support base 200, and the bottom end of the sliding rope 408 is fixedly connected to a pull plate 409. Both the connecting rope 407 and the sliding rope 408 are nylon components.

[0037] In this embodiment, when it is necessary to release the fastening of the pipe, the blocking block 406 is pulled away from the bracket 403, the limiting block 405 is pulled away from the screw 404, the screw 404 is rotated away from the arc seat 300, the bracket 403 is pulled away from the clamp rod 401, and the pull plate 409 is pulled, causing the two sliding ropes 408 to move simultaneously, thereby pulling the two clamp rods 401 away from the arc seat 300 simultaneously, and pulling the arc seat 300 to flip, thereby releasing the fastening of the pipe.

[0038] Working principle: Using appropriate hoisting tools, the pipe is hoisted onto the surface of the support base 200. After the pipe is released from hoisting, the arc-shaped base 300 is pulled and rotated so that the arc-shaped surface of the arc-shaped base 300 abuts against the surface of the pipe. At this time, the elastic force of the spring 402 pushes the clamp rod 401 to automatically engage with the arc-shaped base 300, pushes the clamp bracket 403 to move within the support base 200 and slide into the clamp rod 401, and threadedly installs the screw rod 404 into the clamp bracket 403 and the arc-shaped base 300. Pushes the limit block 405 to move within the clamp bracket 403 and engage with the screw rod 404, and pushes the blocking block 406 to slide into the clamp bracket 403 so that one side of the blocking block 406 contacts one side of the limit block 405, thereby securing the pipe.

[0039] It should be noted that the mounting base 100, support base 200 and arc-shaped base 300 mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs, and will not be elaborated here.

[0040] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
