Abstract
Description
Technical Field
[0001] This utility model belongs to the field of switch machine handling technology, specifically relating to a switch machine transfer tool. Background Technology
[0002] In signaling systems, switch machines are crucial equipment used for switching and locking railway turnouts. During routine maintenance, troubleshooting, and replacement operations, switch machines need to be moved from their installation location. However, switch machines are heavy and lack suitable handles, making manual handling not only labor-intensive but also posing significant safety risks, potentially leading to injury to the machine or personnel. Therefore, lifting handles are typically used for moving switch machines. However, existing lifting handles are not well-suited for different switch machine models, hindering efficient and stable transfer operations and impacting the efficiency of maintenance and replacement work.
[0003] The existing handle has the following problems: (1) The handle cannot be locked in place, and the switch machine can only move horizontally when lifted, but cannot move up and down; (2) The handle is too long and cannot meet the space requirements of the connecting steps in the upper and lower track areas; (3) The handle is not high enough and will get stuck when the switch machine is placed on the angle steel. Summary of the Invention
[0004] To address the inconvenience of using existing switch machines with handles, this invention provides a switch machine transfer tool.
[0005] The switch machine transfer tool of this utility model includes four lifting handles, each with a connected handle and a limiting section for insertion into the bottom hole of the switch machine. It also includes a support frame and four lifting rods. The support frame is formed by an upper rectangular frame and a lower rectangular frame fixedly connected by four connecting rods. A right-angled triangular reinforcing plate is fixedly connected to each of the four right-angled parts of the upper rectangular frame, and each reinforcing plate has a vertically penetrating positioning hole. Each lifting rod includes a grip tube and a fixing rod. The fixing rod is formed by a connecting section and a fixing section perpendicularly connected in an L-shape. The connecting section is detachably connected to one end of the grip tube. The handle and the limiting section of the lifting handle are also perpendicularly connected in an L-shape, and the handle is detachably connected to the other end of the grip tube. The diameter of the fixing section is smaller than the diameter of the positioning hole and the bottom hole of the switch machine, allowing the fixing section to pass through both simultaneously. A fixing element is detachably installed on the fixing section to fix the switch machine to the support frame.
[0006] Furthermore, both the upper and lower rectangular frames are welded together from four steel square tubes, and the connecting rods are also made of steel square tubes. The connecting rods are used to fix the upper and lower rectangular frames together by welding. The triangular reinforcing plate is made of angle iron and is fixed by welding.
[0007] Furthermore, the support frame is 12-14cm high, the limiting section is 14-16cm long, the handle is 14-16cm long, the fixing section is 9-10cm long, and the connecting section is 15-17cm long.
[0008] Furthermore, the two ends of the grip tube are provided with internal threads, and the connecting section and the handle are provided with external threads that match the internal threads. The connection between the grip tube and the connecting section and the handle is a threaded connection.
[0009] Furthermore, the fixed section is threaded, and the fasteners are two nuts. The two nuts are threaded onto the fixed section, and the outer diameter of the two nuts is larger than the diameter of the positioning hole and the bottom hole of the switch machine, so as to fasten the switch machine to the support frame.
[0010] Beneficial Effects: This utility model of a switch machine transfer tool adds a support frame and four lifting rods to the original four lifting handles. First, the lifting handles are inserted into the bottom hole of the switch machine to transfer it onto the support frame. Then, the lifting handles are removed, and the fixing section of the fixing rod of the lifting rod is inserted into the positioning holes on the bottom hole of the switch machine and the reinforcing plate of the support frame. Finally, the lifting rod, switch machine, and support frame are fixed and locked using fasteners. This allows for convenient lifting of the support frame along with the switch machine for transfer in any direction, completing the entire process from transport to track in one go. It is convenient to use, the process is smooth, optimizes personnel division of labor, reduces labor costs, and improves the efficiency of switch machine replacement and emergency response. This utility model adopts a modular design, with a simple and durable structure and convenient operation. Individual modules can be disassembled for repair when damaged, reducing usage costs. They can also be disassembled for easy storage. Lifting the switch machine no longer requires direct contact with the switch machine itself, effectively preventing injuries to hands and feet during transport or accidental slippage. Furthermore, the transfer no longer requires going up and down via connecting stairs, avoiding the previous... The risk of easy slippage and fall is eliminated; the switch machine can be pre-assembled with the transfer tool and switch machine under normal circumstances, and can be moved immediately when needed, which is very convenient; the upper and lower rectangular frames made of steel square tubes are welded and fixed, and the triangular reinforcement plate is set as angle iron and welded to the support frame to ensure that the support frame is firm and reliable; by making the support frame height 12-14cm, it is easier to use; the length of the limiting section is 14-16cm, the length of the handle is 14-16cm, the length of the fixing section is 9-10cm, and the length of the connecting section is 15-17cm, so that the switch machine will not get stuck when placed on the angle iron; by making the grip, connecting section, and handle threaded connection, it is easy to connect and install during use, and easy to disassemble and store after use; by setting the fixing part as two nuts, one nut is located above the bottom hole of the switch machine and the other nut is located below the positioning hole of the reinforcement plate, so that the switch machine and support frame can be firmly secured with two nuts, which facilitates the transfer.

[0014] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.
[0015] like Figure 1-2 As shown, a switch machine transfer tool includes four lifting handles, each handle having a connected handle 10 and a limiting section 11 for insertion into the bottom hole of the switch machine; it also includes a support frame and four lifting rods. The support frame is formed by an upper rectangular frame 1 and a lower rectangular frame 2 fixedly connected by four connecting rods 3. A right-angled triangular reinforcing plate 4 is fixedly connected to each of the four right-angled parts of the upper rectangular frame 1, and each reinforcing plate 4 has a vertically penetrating positioning hole 5; the lifting rod includes a grip tube 6 and a fixing rod. The fixing rod is formed by a connecting section 7 and a fixing section 8 vertically and integrally connected, forming an L-shape. The connecting section 7 is detachably connected to one end of the grip tube 6. The handle 10 and the limiting section 11 of the lifting handle are also vertically and integrally connected in an L-shape. The handle 10 is detachably connected to the other end of the grip tube 6. The diameter of the fixing section 8 is smaller than the diameter of the positioning hole 5 and the bottom hole of the switch machine, so that the fixing section 8 can pass through both the positioning hole 5 and the bottom hole of the switch machine. A fixing element is detachably installed on the fixing section 8 to fix the switch machine to the support frame. There are four positioning holes 5, which correspond to the four bottom holes of the switch machine. After the switch machine is transferred to the support frame, the fixing section 8 can pass through the bottom hole of the switch machine and the positioning hole 5 on the reinforcing plate 4, and then be fixed by the fastener.
[0016] Specifically, both the upper rectangular frame 1 and the lower rectangular frame 2 are welded from four 30×30mm steel square tubes. The connecting rod 3 is also made of the aforementioned steel square tubes. The connecting rod 3 fixes the upper rectangular frame 1 and the lower rectangular frame 2 together by welding. The triangular reinforcing plate 4 is made of 3mm thick angle iron and is fixed by welding. The support frame is 14cm high, the limiting section 11 is 14cm long, the handle 10 is 15cm long, the fixing section 8 is 9.5cm long, and the connecting section 7 is 16cm long. The lifting handle and fixing rod are all made of solid stainless steel. The grip tube 6 is made of 2.5mm thick hollow stainless steel tube, which is both rigid and load-bearing, while also reducing its own weight. The grip tube 6 has internal threads at both ends, and the connecting section 7 and the handle 10 have external threads that mate with the internal threads. The grip tube 6 is connected to the connecting section 7 and the handle 10 by a threaded connection. The fixed section 8 is threaded, and the fasteners are two nuts 9. The two nuts 9 are threaded onto the fixed section 8. The outer diameter of the two nuts 9 is larger than the diameter of the positioning hole 5 and the bottom hole of the switch machine, so as to fasten the switch machine to the support frame.
[0017] The following explanation uses the ZD-J9 type switch machine as an example. The ZD-J9 type switch machine has a smooth outer shell without any handles, and its bottom is flat and directly contacts the ground. During transfer, first install the lifting handle and fixing rod onto the grip tube 6. Use the limiting section 11 of the lifting handle at one end of the grip tube 6 to pass through the bottom hole of the switch machine and lift it directly onto the support frame. After aligning the four bottom holes of the switch machine with the four positioning holes 5 on the reinforcing plate 4, replace the fixing section 8 of the fixing rod at the other end of the grip tube 6 and pass it through the bottom hole of the switch machine and the positioning holes 5 on the reinforcing plate 4. Secure it with two nuts 9. In this way, the switch machine, support frame, and lifting rod are assembled and fixed together. The four positioning holes 5 on the reinforcing plate 4 are opened according to the data hole positions of the ZD-J9 switch machine. Taking full account of the load-bearing capacity, angle iron is given priority in material selection. Considering factors such as self-weight, load-bearing capacity, and economy, 3mm thick angle iron is sufficient. The overall height of the support frame is 14cm, which makes it easier to use.
[0018] Next, the entire unit was moved to the edge of the platform. Six people were responsible for receiving and lifting the equipment in the track area below the platform, while two people were responsible for delivery and safety on the platform. Of the six people in the track area, four lifted the lifting pole, and the other two lifted the support frame frame to assist in the effort while providing safety protection. The entire process was safe and controllable, with reasonable personnel arrangements, minimal individual burden, and reduced possibility of accidents.
[0019] After being lowered into the track area, the device is transported to the designated location via a rail flatcar. At this point, the nut 9 on the lifting rod fixing section 8 is removed, and the fixing section 8 is taken off. The limiting section 11 of the lifting handle at the other end of the grip tube 6 is inserted into the bottom hole of the switch machine to lift the switch machine. The machine is then moved to the position of the angle steel. The angle steel is 12.5cm high, and the limiting section 11 is 14cm high. This height is sufficient to cover the angle steel and the ground, effectively preventing the rod from getting stuck and hands from being crushed, ensuring safety. The limiting section 11 of the lifting handle is then removed and placed aside. The entire process is complete and is safe and controllable.
[0020] Of course, when used with other types of switch machines, new positioning holes 5 can be made on the reinforcing plate 4 according to the data hole positions of the four bottom holes on the other type of switch machine. The above-mentioned switch machine transfer tool is easy to disassemble and assemble, and can be stored together with the switch machine spare parts for easy transfer and transportation when needed.
[0021] Unless otherwise specified, all technologies mentioned above refer to existing technologies.
[0022] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification.
