Description

Technical Field

[0001] This application relates to the field of lifting tools, and more particularly to a lifting tool for porcelain vases. Background Technology

[0002] In electrostatic precipitators, porcelain insulators play a crucial role. Their main function is to provide insulation between the high-voltage electrodes and the low-voltage components. In an electrostatic precipitator, the high-voltage electric field is used to adsorb and collect tar particles, while the porcelain insulators ensure that there is no electrical connection between the high-voltage components and other low-voltage parts of the equipment (such as the housing and supports), thereby preventing current leakage and short circuits.

[0003] When a large amount of tar, dust, or other contaminants accumulates on the surface of a porcelain insulator and cannot be completely removed by washing, the insulator needs to be replaced. In related technologies, a gantry crane needs to be erected to remove the insulator from the insulation box when replacing it. However, erecting a gantry crane is time-consuming and labor-intensive, and the gantry crane is not securely fixed, posing a threat to the safety of the workers. Utility Model Content

[0004] In order to reduce the possibility of threatening the lives of workers during the handling of porcelain bottles, this application provides a porcelain bottle lifting tool.

[0005] The porcelain bottle lifting tool provided in this application adopts the following technical solution:

[0006] A porcelain bottle lifting tool, characterized in that: it includes a base, the edge of which is provided with multiple bolt threaded connections, a connecting rod is vertically arranged on the base, and a horizontally arranged lifting rod is fixedly connected to the end of the connecting rod away from the base, and the lifting rod is provided with a lifting lug for hooking the lifting tool.

[0007] By adopting the above technical solution, the base is installed on the working surface through the connecting hole, the lifting rod is supported by the connection, and the lifting tool is hooked on the lifting lug. The porcelain bottle is taken out of the insulation box using the base, connecting rod, lifting rod, and lifting tool. The connecting rod and lifting rod facilitate quick installation and disassembly, so that the lifting tool can be quickly positioned when in use, reducing installation time. Furthermore, the base is installed on the working surface through the connecting hole, which increases the stability of the lifting tool during the lifting process, thereby reducing the possibility of threatening the life safety of workers during the handling of porcelain bottles.

[0008] Optionally, a vertically arranged connecting pipe is fixedly connected to the base, the connecting rod is inserted into the connecting pipe, and a locking assembly is provided on the base to lock the connecting rod and the connecting pipe.

[0009] By adopting the above technical solution, the connecting rod and connecting pipe are locked by the locking assembly, thereby improving the stability of the porcelain bottle during hoisting.

[0010] Optionally, a connecting frame is fixedly connected to the base. The connecting frame includes a horizontal rod, which is fixedly connected to a connecting pipe. The locking assembly includes a threaded rod that is threadedly connected to the horizontal rod. A fixing block is fixedly connected to one end of the threaded rod away from the connecting pipe. A first threaded hole is provided on the connecting pipe that is threadedly connected to the threaded rod, and a second threaded hole is provided on the connecting rod that is threadedly connected to the threaded rod.

[0011] By adopting the above technical solution, when it is necessary to fix the connecting pipe and the connecting rod, the threaded rod is screwed on so that the threaded rod passes through the connecting pipe and the connecting rod in sequence and is located in the first threaded hole and the second threaded hole, thereby achieving a stable connection between the connecting pipe and the connecting rod.

[0012] Optionally, a connecting frame is fixedly connected to the base. The connecting frame includes a horizontal rod, which is fixedly connected to a connecting tube. The locking assembly includes a positioning pin that is horizontally inserted into the horizontal rod. A mounting block is fixedly connected to one end of the positioning pin away from the horizontal rod. A first spring is sleeved on the positioning pin. One end of the first spring is fixedly connected to the mounting block, and the other end of the first spring is fixedly connected to the horizontal rod. A first insertion hole for the positioning pin to be inserted is provided on the connecting tube, and a second insertion hole for the positioning pin to be inserted is provided on the connecting rod.

[0013] By adopting the above technical solution, when it is necessary to fix the connecting pipe and the connecting rod, the positioning pin is passed through the connecting pipe and the connecting rod in sequence and located in the first insertion hole and the second screw insertion hole, which facilitates the disassembly and installation of the connecting pipe and the connecting rod. By setting the first spring, the possibility of the pin being lost is reduced.

[0014] Optionally, the lifting rod includes a plug rod and a sleeve. The sleeve is fixedly connected to the end of the connecting rod away from the base. The plug rod is inserted into the sleeve and moves along the length of the sleeve. A cylinder is horizontally arranged on the sleeve. The telescopic rod of the cylinder is fixedly connected to the end of the plug rod away from the sleeve. The lifting lug is arranged at the end of the plug rod away from the sleeve.

[0015] By adopting the above technical solution, when it is necessary to adjust the length of the lifting rod, the cylinder is activated to drive the telescopic rod to move along the length of the sleeve, thereby adjusting the length of the lifting rod according to the distance between the porcelain insulator and the connecting rod, thus improving the flexibility of the lifting tool.

[0016] Optionally, the connecting rod includes a fixed rod and a rotating rod, and a connecting assembly is provided between the fixed rod and the rotating rod.

[0017] By adopting the above technical solution and setting up connecting components, it is easy to adjust the direction of the hanging rod according to the position of the porcelain bottle.

[0018] Optionally, the connecting assembly includes a ratchet and a pawl that are adapted to each other. The fixed rod has a slot at one end near the rotating rod, and the ratchet is installed in the slot. The rotating rod has a groove on the side wall near the fixed rod. One end of the pawl is hinged to the side wall of the groove. A second spring is provided on the pawl. One end of the second spring is fixedly connected to the pawl, and the other end of the second spring is fixedly connected to the bottom of the groove. When the second spring is in a compressed state, the pawl is located in the groove.

[0019] By adopting the above technical solution, the design of the ratchet and pawl allows the fixed rod and the rotating rod to mesh with each other to form a stable connection. The ratchet and pawl not only have a high load-bearing capacity, but also prevent the connecting parts from loosening or falling off during operation, thereby improving the stability and reliability of the connection.

[0020] Optionally, a reinforcing rod is provided on the connecting rod, one end of which is fixedly connected to the connecting rod, and the other end of which is fixedly connected to the sleeve.

[0021] By adopting the above technical solution, the stability of the connection between the connecting rod and the lifting rod is increased by setting up a reinforcing rod, which reduces the possibility of the lifting rod bending or deforming under stress, thereby improving the structural stability of the entire lifting tool.

[0022] Optionally, a handrail is fixedly connected to the base.

[0023] By adopting the above technical solution, the base can be easily picked up and placed by setting up a handrail.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. Install the base on the working surface through the connecting hole, support the lifting rod through the connection, hook the lifting tool onto the lifting lug, and use the base, connecting rod, lifting rod, and lifting tool to remove the porcelain bottle from the insulation box. The connecting rod and lifting rod facilitate quick installation and disassembly, allowing the lifting tool to be quickly positioned during use, reducing installation time. Furthermore, installing the base on the working surface through the connecting hole increases the stability of the lifting tool during the lifting process, thereby reducing the possibility of threatening the life safety of workers during the handling of porcelain bottles.

[0026] 2. The connecting rod and connecting pipe are locked by a locking assembly to improve the stability during the hoisting of the porcelain insulator;

[0027] 3. When it is necessary to fix the connecting pipe and the connecting rod, the positioning pin is passed through the connecting pipe and the connecting rod in sequence and located in the first insertion hole and the second screw insertion hole, which facilitates the disassembly and installation of the connecting pipe and the connecting rod. By setting the first spring, the possibility of the pin being lost is reduced. Attached Figure Description

[0043] Example 2

[0044] Reference Figure 3 and Figure 4The porcelain bottle lifting tool includes a circular base 1 with multiple connection holes 11 for bolt threaded connections. The multiple connection holes 11 are arranged along the circumference of the base 1. A vertically arranged connecting pipe 12 is fixedly connected to the base 1. A connecting rod 2 is arranged inside the connecting pipe 12 and moves along the length of the connecting pipe 12. A lifting rod 3 is fixedly connected to the end of the connecting rod 2 away from the base 1. A lifting lug 321 is fixedly connected to the end of the lifting rod 3. The lifting lug 321 is used to hook the lifting tool. In this embodiment, the lifting tool is a hand chain hoist. A locking assembly 4 is also provided on the base 1 to lock the connecting pipe 12 and the connecting rod 2.

[0045] A connecting frame 13 is provided on the base 1. The connecting frame 13 includes a horizontal rod 131. A vertical rod 132 is fixedly connected to both ends of the horizontal rod 131. The end of the vertical rod 132 away from the horizontal rod 131 is fixedly connected to the base 1. The side wall of the horizontal rod 131 is fixedly connected to the connecting pipe 12. A connecting plate 1311 is fixedly connected to the side wall of the horizontal rod 131 near the base 1.

[0046] Reference Figure 4 and Figure 5 The locking assembly 4 includes a positioning pin 41B, which is inserted into the connecting plate 1311. A mounting block 42B is fixedly connected to the end of the positioning pin 41B away from the connecting tube 12. A first spring 43B is sleeved on the positioning pin 41B.

A first insertion hole 122 for the positioning pin 41B to be inserted is provided on the connecting tube 12, and a second insertion hole 214 for the positioning pin 41B to be inserted is provided on the fixing rod 21.

[0047] When it is necessary to lock the fixing rod 21 and the connecting pipe 12, the positioning pin 41B is passed through the connecting plate 1311, the connecting pipe 12 and the fixing rod 21 in sequence, thereby fixing the connecting pipe 12 and the fixing rod 21.

[0048] Reference Figure 3 , Figure 6 and Figure 7The connecting rod 2 includes a fixed rod 21 and a rotating rod 22. The fixed rod 21 is inserted into the connecting tube 12 and moves along the length of the connecting tube 12. A connecting block 221 is fixedly connected to one end of the rotating rod 22 near the fixed rod 21. Grooves 222 are provided on a pair of opposite sidewalls of the connecting block 221. An insertion groove 211 is provided on one end of the fixed rod 21 near the rotating rod 22. A connecting assembly 5 is provided between the fixed rod 21 and the connecting rod 2. The connecting assembly 5 includes a ratchet 51 and a pawl 52 that are adapted to each other. The ratchet 51 is installed in the insertion groove 211. One end of the pawl 52 is fixedly connected to the sidewall of the groove 222. A second spring 521 is also provided on the pawl 52. One end of the second spring 521 is fixedly connected to the pawl 52, and the other end of the second spring 521 is fixedly connected to the bottom of the groove 222. When the second spring 521 is compressed, the pawl 52 is located in the groove 222.

[0049] When the direction of the boom 3 needs to be adjusted, simply hold the rotating rod 22 and start rotating it. During the rotation of the rotating rod 22, the second spring 521 is compressed, and the pawl 52 is located in the groove 222. When the boom 3 reaches the target position, stop rotating the rotating rod 22. At this time, the second spring 521 returns to its original length, and the pawl 52 abuts against the ratchet 51, thereby fixing the fixed rod 21 and the connecting rod 2.

[0050] Reference Figure 3 and Figure 4 The lifting rod 3 includes a plug rod 31 and a sleeve 32. The plug rod 31 is disposed inside the sleeve 32 and moves along the length of the sleeve 32.

A horizontally arranged cylinder 311 is fixedly connected to the sleeve 32. The telescopic rod of the cylinder 311 is fixedly connected to the end of the plug rod 31 away from the sleeve 32.

[0051] When it is necessary to adjust the length of the boom 3, start the cylinder 311 to drive the telescopic rod to move along the length direction of the sleeve 32 until the boom 3 reaches the target length.

[0052] An inclined reinforcing rod 213 is fixedly connected to the rotating rod 22. One end of the reinforcing rod 213 is fixedly connected to the rotating rod 22, and the other end of the reinforcing rod 213 is fixedly connected to the sleeve 32. A support rod 14 is fixedly connected to both sides of the connecting pipe 12 on the base 1. An inclined stabilizing rod 15 is also fixedly connected to the connecting pipe 12. One end of the stabilizing rod 15 is fixedly connected to the connecting pipe 12, and the other end of the stabilizing rod 15 is fixedly connected to the base 1.

[0053] By setting a reinforcing rod 213, the stability of the connection between the rotating rod 22 and the sleeve 32 is increased, reducing the possibility of bending or deformation of the rod under stress. By setting a stabilizing rod 15, the stability of the connection between the connecting pipe 12 and the base 1 is enhanced.

[0054] The implementation principle of Example 2 is as follows:

[0055] When it is necessary to remove the porcelain insulator from the insulation box, first remove the manhole near the insulation box, hold the handle 14 with both hands and move the base 1 to the manhole, then use the threaded rod 41A and the connecting hole 11 to fix the base 1 to the manhole, then hang the hook of the hand chain hoist on the lifting lug 321, then insert the fixing rod 21 into the connecting pipe 12, and finally pass the positioning pin 41B through the connecting plate 1311, the connecting pipe 12 and the fixing rod 21 in sequence to fix the connecting pipe 12 and the fixing rod 21.

[0056] When it is necessary to adjust the direction of the lifting rod 3 according to the position of the porcelain bottle, simply hold the rotating rod 22 and start rotating it. During the rotation of the rotating rod 22, the second spring 521 is compressed, and the pawl 52 is located in the groove 222. When the lifting rod 3 reaches the target position, stop rotating the rotating rod 22. At this time, the second spring 521 returns to its original length, and the pawl 52 abuts against the ratchet 51, thereby fixing the fixed rod 21 and the connecting rod 2.

[0057] When it is necessary to adjust the length of the lifting rod 3 according to the distance between the porcelain bottle and the connecting rod 2, the cylinder 311 is activated to drive the telescopic rod to move along the length direction of the sleeve 32 until the lifting rod 3 reaches the target length.

[0058] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
