Description

Technical Field

[0001] This utility model belongs to the field of water conservancy equipment technology, specifically relating to a gate tie rod pin device. Background Technology

[0002] Gates are crucial facilities for controlling water flow and are key components of hydropower stations, reservoirs, and other water conservancy projects. Typically, gates on a dam are opened and closed using tie rods mounted on them. The tie rods are connected by pins, transmitting the opening and closing force to the gate. During operation, the tie rods primarily bear tensile force, while the pins bear significant shear force. In large and medium-sized water conservancy projects, due to the gate's considerable weight, the shear stress on the pins increases significantly to ensure proper opening and closing. To meet strength requirements, the pin diameter usually needs to be increased accordingly; in actual projects, each pin often weighs several hundred kilograms.

[0003] Currently, in most projects, the installation and removal of pins are still mainly done manually. Especially in dams with multiple gates, the pin installation and removal operations are not only labor-intensive and time-consuming, but also difficult to meet the rapid response requirements for sudden scheduling in water conservancy projects, such as flood control and flood prevention.

[0004] Furthermore, as the size of the pin increases, it becomes more cumbersome during installation and disassembly, significantly increasing the difficulty of operation, especially in environments with limited space within the dam or complex installation conditions. In actual operation, workers often use tools such as hammers and sledgehammers to strike the end of the pin to assist in its installation or disassembly. This method is not only inefficient but also easily causes mechanical damage to the pin itself, reducing its service life and potentially affecting the operational safety of the entire opening and closing system, posing a significant engineering safety hazard.

[0005] Therefore, we propose a gate lever pin device to solve the above-mentioned technical problems. Utility Model Content

[0006] In order to solve the technical problems existing in the prior art, this utility model proposes a gate pull rod pin device.

[0007] The technical solution adopted in this utility model is as follows:

[0008] A gate pull rod pin device includes a pull rod and two connecting mechanisms symmetrically arranged on both sides of the pull rod. The pull rod includes an upper pull rod and a lower pull rod inserted into the upper pull rod. The connecting mechanism includes a baffle and a pin. The baffle is located inside the lower pull rod, and the pin passes through the upper and lower pull rods and is threadedly connected to the baffle.

[0009] In a further technical solution, fixing holes are symmetrically opened on both sides of the baffle, and baffle bolts are installed in the fixing holes. The baffle bolts are threadedly connected to the inner wall of the lower tie rod.

[0010] In a further technical solution, the fixing hole is a strip-shaped hole, and the baffle bolt is located in the middle of the fixing hole.

[0011] In a further technical solution, a guide groove is provided in the middle of the baffle, and a baffle thread matching the outer thread of the pin is provided in the guide groove.

[0012] In a further technical solution, a handle is provided at the outer end of the pin.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] 1. This utility model replaces the traditional hammering operation with a threaded connection, making the installation of the pin more convenient, effectively reducing manual operation time and labor intensity, while avoiding mechanical damage to the pin caused by traditional hammering, effectively extending the service life of the pin, and further improving the operational reliability and safety of the entire opening and closing system.

[0015] 2. Compared with the traditional integrated pin shaft, this gate tie rod pin shaft device disassembles the pin shaft without reducing its shear bearing capacity, thereby reducing the size and weight of the pin shaft. This effectively reduces the difficulty of manual handling and installation, making it suitable for water conservancy projects with limited space or complex installation conditions. It facilitates the rapid, efficient, and safe completion of multiple tie rod connection operations, meeting the actual needs of water conservancy projects for rapid dispatch and emergency response in emergency situations such as flood control and flood prevention.

[0016] 3. The fixing hole of this utility model is a strip hole. When the baffle bolt is connected to the inner wall of the lower section tie rod, the baffle can use the adjustment space provided by the strip hole to move relative to the lower section tie rod, thereby avoiding the threaded part from being damaged by tensile and compressive stress during the pin shaft is subjected to force, and effectively improving the working stability and safety reliability of the pin shaft device.

[0023] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] See Figures 1-4 This utility model provides a gate pull rod pin device, including a pull rod and two connecting mechanisms symmetrically arranged on both sides of the pull rod. The pull rod includes an upper pull rod 1 and a lower pull rod 2 inserted into the upper pull rod 1. The connecting mechanism includes a baffle 3 and a pin 4. The baffle 3 is located inside the lower pull rod 2. The pin 4 passes through the upper pull rod 1 and the lower pull rod 2 and is threadedly connected to the baffle 8.

[0025] The specific usage of this gate tie rod pin device is as follows:

[0026] The upper section 1 and lower section 2 have corresponding pin holes on both sides. During assembly, the lower section 2 is first inserted into the upper section 1, and the pin holes provide initial axial positioning of the upper and lower sections. Then, the operator can pass the pins 4 sequentially through the pin holes of the upper and lower sections 1 and 2, and screw them into the baffle 3 inside the lower section 2 to lock them in place, thus achieving a reliable connection between the upper and lower sections. This gate rod pin device uses a threaded connection instead of the traditional hammering method for inserting the pins, making the installation of the pins 4 more convenient and effectively reducing manual operation time and labor intensity. At the same time, this installation method avoids the mechanical damage to the pins 4 caused by traditional hammering, effectively extending the service life of the pins 4 and further improving the operational reliability and safety of the entire opening and closing system. Compared to the traditional integrated pin 4, this gate tie rod pin device disassembles the pin 4 without reducing its shear bearing capacity, thereby reducing the size and weight of the pin 4. This effectively reduces the difficulty of manual handling and installation, making it suitable for water conservancy projects with limited space or complex installation conditions. It facilitates the rapid, efficient, and safe completion of multiple tie rod connection operations, meeting the actual needs of water conservancy projects for rapid dispatch and emergency response in emergency situations such as flood control and flood prevention.

[0027] In one specific implementation, see Figure 2 and Figure 3 The baffle 3 has symmetrical fixing holes 5 on both sides, and the fixing holes 5 are provided with baffle bolts 6, which are threaded to the inner wall of the lower tie rod 2.

[0028] The baffle 3 is securely installed on the inner wall of the lower tie rod 2 through the cooperation of the fixing hole 5 and the baffle bolt 6, which effectively ensures the stability of the structural fit during the installation of the pin 4 and improves the reliability and safety of the overall connection.

[0029] In one specific implementation, see Figure 2 The fixing hole 5 is a strip-shaped hole, and the baffle bolt 6 is located in the middle of the fixing hole 5.

[0030] The fixing hole 5 is a strip-shaped hole. When the baffle bolt 6 is connected to the inner wall of the lower section tie rod 2, the baffle 3 can use the adjustment space provided by the strip-shaped hole to move relative to the lower section tie rod 2. This prevents the threaded part from being damaged by tensile and compressive stress during the process of the pin shaft 4 being under force, and effectively improves the working stability and safety reliability of the pin shaft device.

[0031] In one specific implementation, see Figure 2 and Figure 4The baffle 3 has a guide groove 7 in the middle, and the guide groove 7 has a baffle thread 8 that matches the outer thread of the pin 4.

[0032] The baffle 3 has a guide groove 7 in the middle, which is tightly threaded with the pin 4, significantly improving the guidance and alignment accuracy during the assembly process, making it easier for the pin 4 to be inserted smoothly and improving the installation efficiency.

[0033] In one specific implementation, see Figure 1 The outer end of the pin 4 is provided with a handle 9.

[0034] The handle 9 at the end of the pin 4 makes it easy for operators to grip and rotate the pin 4, enabling quick and convenient installation and disassembly.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
