Description

Technical Field

[0001] This application relates to the technical field of replacement of lifting shaft detection devices, specifically a tooling for replacing the lifting shaft detection device of a flat steel gate. Background Technology

[0002] Replacement of the shaft inspection device refers to the process of regularly inspecting and maintaining the shaft inspection device, and replacing it when necessary.

[0003] An existing patent (publication number: CN218860116U) discloses an installation tool for a lifting shaft detection device, relating to the field of lifting shaft detection device replacement. It includes a support base plate with a holding cylinder on its upper surface. The holding cylinder has a through hole at its center for the through rod of the lifting shaft detection device to pass through, extending downwards out of the support base plate. The holding cylinder also has evenly distributed clamping mechanisms, including a drive rod, a connecting rod assembly, and a clamping plate. In its natural state, by driving the rotation of the drive rod, the clamping plate can be moved back and forth within an arc-shaped groove via the connecting rod assembly, ensuring the stability of the counterweight within the holding cylinder and guaranteeing the proper stacking of the counterweight. The outer walls of the holding cylinder also have symmetrically arranged lifting lugs on the left and right sides for use with a drive hoist to lift the counterweight for replacement. This device has a simple structure, is easy to operate, and has low cost. It eliminates the need for a support frame, reducing safety hazards, and allows for quick and efficient replacement, greatly improving maintenance efficiency and quality.

[0004] The aforementioned installation tool uses a counterweight to compress the connecting rod and spring, causing the clamping plate to secure the counterweight. However, the counterweights need to be stacked inside the container. When the first counterweight is placed inside the container, the clamping plate will rotate into the container and be in a clamping state, which will affect the placement of subsequent counterweights. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a replacement fixture for a flat steel gate hanger shaft detection device. This fixture offers advantages such as convenient stacking and installation of counterweights, providing convenience for workers, and complete positioning of the counterweights to improve their stability. It solves the problem that existing hanger shaft detection device installation tools are limited by their clamping structures when installing counterweights, which is inconvenient and increases the workload.

[0006] To achieve the above objectives, this application provides the following technical solution: a replacement fixture for a flat steel gate shaft detection device, comprising a base, a holding cylinder fixedly connected to the upper surface of the base, four equidistantly arranged mounting rods inside the holding cylinder, and equidistantly arranged counterweights inside the holding cylinder. Each counterweight has four equidistantly arranged first mounting holes inside, and each counterweight is slidably sleeved with the outer circumference of the mounting rod through the first mounting holes. A pressure plate is provided inside the holding cylinder, and four equidistantly arranged second mounting holes are provided inside the pressure plate. The pressure plate is slidably sleeved with the outer circumference of the mounting rod through the second mounting holes. Each mounting rod has a first threaded portion at its top end, and each mounting rod is threadedly connected with a positioning ring through the first threaded portion.

[0007] The above solution addresses the inconvenience and increased workload of installing counterweights in existing shaft detection devices due to the limitations of their clamping structures. By installing multiple mounting rods inside the container, the counterweights can be slidably fitted onto the mounting rods. Furthermore, pressure plates and positioning rings are used to position the counterweights, facilitating their stacking and installation. This avoids limitations during installation, provides convenience for workers, and ensures complete positioning of the counterweights, further improving their stability.

[0008] Furthermore, the base has a perforation inside, which is located on the central axis of the base.

[0009] With the above solution, the perforation on the base axis is used for the through rod of the lifting shaft detection device to pass through for subsequent replacement work.

[0010] Furthermore, each of the mounting rods has a second threaded portion at its bottom, and the base has four equally spaced threaded holes inside, with the second threaded portion being threadedly connected to the base through the threaded holes.

[0011] The above method allows the mounting rod to be installed onto the base via the second threaded part and threaded hole, facilitating the installation and removal of the mounting rod.

[0012] Furthermore, an auxiliary ring is fixedly connected to the upper surface of each counterweight, and an auxiliary groove is formed on the outer circumferential surface of the auxiliary ring.

[0013] The above method allows for the placement and removal of counterweights via an auxiliary ring. The auxiliary groove on the auxiliary ring facilitates gripping with fingers, providing convenience for the placement and removal of counterweights.

[0014] Furthermore, each of the counterweights has a docking groove at its bottom, and the outer circumferential surface of the auxiliary ring is slidably inserted into the adjacent counterweight through the docking groove.

[0015] The above scheme allows the upper counterweight to be fitted onto the lower auxiliary ring via its bottom docking groove, thus connecting the upper and lower counterweights. This enables the longitudinally distributed counterweights to be connected into a whole, increasing the overall stability of the counterweights during stacking and facilitating their stacking and transportation.

[0016] Furthermore, the counterweight, auxiliary ring, and pressure plate are all provided with through holes, and the through holes and perforations of the counterweight, auxiliary ring, and pressure plate are located on the same axis.

[0017] With the above scheme, the through holes inside the counterweight, auxiliary ring, and pressure plate are used for the through rod in the hanging shaft detection device to pass through, so as to avoid obstructing the installation of the through rod.

[0018] Furthermore, two lifting lugs are fixedly connected to the outer circumferential surface of the container, and the two lifting lugs are symmetrically arranged on both sides of the container.

[0019] The above method allows for connection to an external drive hoist via lifting lugs, enabling the container cylinder to be lifted using both the external drive hoist and lifting lugs.

[0020] Furthermore, the mounting rod is made of aluminum alloy, and its outer surface is coated with an anti-rust coating.

[0021] Through the above solution, the aluminum alloy mounting rod has the characteristics of being lightweight and high-strength, with low weight and high stability. The anti-rust coating on the outer surface of the mounting rod can effectively prevent surface corrosion and extend the service life of the mounting rod.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This flat steel gate hanger shaft detection device replaces the tooling by setting multiple mounting rods inside the container cylinder. The counterweight is slidably sleeved on the mounting rods, and the counterweight is positioned using pressure plates and positioning rings. This facilitates the stacking and installation of the counterweight, avoids restrictions during counterweight installation that could affect normal operation, provides convenience for workers, and completely positions the counterweight, further improving its stability. It solves the problem that existing hanger shaft detection devices are limited by their clamping structures when installing counterweights, making installation inconvenient and increasing the workload.

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] Please see Figure 1 , Figure 3 and Figure 4 The replacement fixture for the flat steel gate shaft detection device in this embodiment includes a base 1. A container 2 is fixedly connected to the upper surface of the base 1. The container 2 has four equidistantly arranged mounting rods 3 inside. The container 2 also has equidistantly arranged counterweights 4 inside. Each counterweight 4 has four equidistantly arranged first mounting holes 5 inside. Each counterweight 4 is slidably sleeved with the outer circumference of the mounting rod 3 through the first mounting holes 5. The container 2 has a pressure plate 6 inside. The pressure plate 6 has four equidistantly arranged second mounting holes 7 inside. The pressure plate 6 is slidably sleeved with the outer circumference of the mounting rod 3 through the second mounting holes 7. Each mounting rod 3 has a first threaded part 8 at its top end. Each mounting rod 3 is threadedly connected to a positioning ring 9 through the first threaded part 8.

[0033] Please see Figure 2 , Figure 3 and Figure 4 The base 1 has a through hole 12 inside, which is located on the central axis of the base 1. The through hole 12 on the axis of the base 1 is used for the through rod of the hanging shaft detection device to pass through for subsequent replacement work.

[0034] Please see Figure 3 and Figure 4Each mounting rod 3 has a second threaded part 14 at its bottom. The base 1 has four equally spaced threaded holes 15 inside. The second threaded part 14 is threaded to the base 1 through the threaded holes 15. The mounting rod 3 can be installed on the base 1 through the second threaded part 14 and the threaded holes 15, which facilitates the installation and removal of the mounting rod 3.

[0035] Please see Figure 5 Each counterweight 4 has an auxiliary ring 10 fixedly connected to its upper surface. The outer circumferential surface of the auxiliary ring 10 has an auxiliary groove 16, which allows the counterweight 4 to be picked up and put down. The auxiliary groove 16 on the auxiliary ring 10 is easy for fingers to grasp, providing convenience for picking up and putting down the counterweight 4.

[0036] Please see Figure 5 Each counterweight 4 has a docking groove 11 at its bottom. The outer circumference of the auxiliary ring 10 is slidably inserted into the adjacent counterweight 4 through the docking groove 11. The upper counterweight 4 can be fitted onto the lower auxiliary ring 10 through the docking groove 11 at its bottom, thus completing the docking of the upper and lower counterweights 4. This allows the longitudinally distributed counterweights 4 to be docked into a whole, increasing the overall stability of the counterweights 4 during stacking and facilitating the stacking and transportation of the counterweights 4.

[0037] Please see Figure 3 , Figure 4 and Figure 5 The counterweight 4, auxiliary ring 10 and pressure plate 6 are all provided with through holes. The through holes of the counterweight 4, auxiliary ring 10 and pressure plate 6 are located on the same axis as the through hole 12. The through holes inside the counterweight 4, auxiliary ring 10 and pressure plate 6 are used for the through rod in the hanging shaft detection device to pass through, so as to avoid obstructing the installation of the through rod.

[0038] Please see Figure 1 , Figure 2 and Figure 3 Two lifting lugs 13 are fixedly connected to the outer circumference of the container cylinder 2. The two lifting lugs 13 are symmetrically arranged on both sides of the container cylinder 2. They can be connected to an external drive hoist through the lifting lugs 13, and the container cylinder 2 can be lifted by the external drive hoist and the lifting lugs 13.

[0039] Please see Figure 3 and Figure 4 The mounting rod 3 is made of aluminum alloy and its outer surface is coated with an anti-rust coating. The aluminum alloy mounting rod 3 has the characteristics of being lightweight and high-strength, with low weight and high stability. The anti-rust coating on the outer surface of the mounting rod 3 can effectively prevent its surface corrosion and extend the service life of the mounting rod 3.

[0040] This embodiment of a flat steel gate shaft detection device replacement fixture uses multiple mounting rods 3 inside the container 2 to slide the counterweight 4 onto the mounting rods 3. A pressure plate 6 and a positioning ring 9 are used to position the counterweight 4, facilitating the stacking and installation of the counterweight 4. This avoids restrictions during installation, preventing disruption to normal operations and providing convenience for workers. Furthermore, the fixture fully positions the counterweight 4, further improving its stability. This solves the problem that existing shaft detection device installation tools are limited by their clamping structures, making the installation of the counterweight 4 inconvenient and increasing the workload.

[0041] It should be noted that the outer circumferential surface of the positioning ring 9 is provided with equidistant anti-slip protrusions, which can increase the friction between the ring and the palm, making it easier to rotate the positioning ring 9.

[0042] The working principle of the above embodiments is as follows:

[0043] The mounting rod 3 can be rotated and installed on the base 1 through the second threaded part 14 and the threaded hole 15 on the base 1. When installing the counterweight 4, the counterweight 4 is sleeved on the mounting rod 3 through the first mounting hole 5 on the counterweight 4. The counterweight 4 is then stacked and placed inside the container 2. After the counterweight 4 is installed, the pressure plate 6 is sleeved on the top of the mounting rod 3 through the second mounting hole 7 on the pressure plate 6. Then, the positioning ring 9 is rotated and sleeved on the first threaded part 8 at the top of the mounting rod 3, and the positioning ring 9 is tightened to press the pressure plate 6 below it and the stacked counterweight 4. Positioning is then completed, and the installation and positioning of counterweight 4 are fully positioned, increasing the stability of counterweight 4 and preventing it from being restricted during installation. It also facilitates the installation and disassembly of counterweight 4. Counterweight 4 can be picked up and put down through the auxiliary groove 16 on the auxiliary ring 10, providing convenience for picking up and putting down counterweight 4. The upper and lower adjacent counterweight 4 are connected through the auxiliary ring 10 and the docking groove 11, so that the counterweight 4 distributed vertically can be connected into a whole, increasing the overall stability of counterweight 4 during stacking and facilitating the stacking and transportation of counterweight 4.
