Description
Technical Field
[0001] This application relates to the field of train maintenance technology, and in particular to a glass removal device. Background Technology
[0002] Trains are an important means of transportation. They contain various types of glass, including windshields, door windows, and window panes, which are secured to mounting points on the train using adhesive. During train maintenance, it is necessary to remove the windshields, door windows, or window panes to be replaced.
[0003] In existing technology, the glass is removed from the train by breaking it with a hammer.
[0004] However, using a hammer to break the glass during disassembly can easily cause deformation of the installation part. Utility Model Content
[0005] The purpose of this application is to provide a glass removal device to solve the problem that the installation part is easily deformed when removing train glass in the prior art.
[0006] A glass removal device, comprising:
[0007] A cutting line, the cutting line being used to pass through the adhesive used to fix the glass;
[0008] A connecting component for connecting the glass;
[0009] A handheld component is connected to the connecting assembly via the cutting line; the handheld component is configured to drag the cutting line relative to the connecting adhesive under the action of an external force to cut the connecting adhesive.
[0010] A heater connected to the cutting wire to heat the cutting wire.
[0011] In some embodiments, the heater includes a metal block and an electromagnetic induction component. The metal block is connected to the cutting line, and the electromagnetic induction component cooperates with the metal block. The electromagnetic induction component generates eddy currents in the metal block under the principle of electromagnetic induction to heat the metal block, and the metal block is used to conduct heat to the cutting line.
[0012] In some embodiments, the glass removal device further includes a reciprocating mechanism connected to the cutting line; the reciprocating mechanism is configured to periodically pull the cutting line back and forth between the handpiece and the connecting assembly.
[0013] In some embodiments, the reciprocating mechanism includes a power component and a power storage component. The power component is disposed in the handheld component, and the power storage component is disposed on the connecting component. The cutting wire connects the power component and the power storage component. The power component is used to periodically pull and release the cutting wire. When the power component pulls the cutting wire, it pulls the cutting wire from the connecting component to the handheld component. The power storage component is configured to store force when the cutting wire is pulled from the connecting component to the handheld component, and when the power component releases the cutting wire, it uses the stored force to pull the cutting wire from the handheld component to the connecting component.
[0014] In some embodiments, the power storage component is a tension spring, one end of which is connected to the connecting component and the other end of which is connected to the cutting wire; the tension spring is configured to generate elastic force by being stretched by the cutting wire to store power when the cutting wire is pulled from the connecting component to the handheld component, and to pull the cutting wire from the handheld component to the connecting component by the elastic force when the power component releases the cutting wire.
[0015] In some embodiments, the power-storing assembly includes a reel frame, a reel, and a torsion spring. The reel frame is mounted on the connecting assembly, and the reel is rotatably mounted on the reel frame. A portion of the cutting wire is wound around the reel. The reel frame has a shaft, and the torsion spring is sleeved on the shaft. The torsion spring has two connectors, one of which is connected to the reel, and the other is connected to the reel frame. The torsion spring is configured such that when the cutting wire is pulled from the connecting assembly toward the handheld component, the cutting wire causes the reel to rotate clockwise relative to the reel frame, and the reel twists and deforms under the drive of the reel to generate elastic force for power storage. When the power assembly releases the cutting wire, the elastic force causes the reel to rotate counterclockwise relative to the reel frame, thereby pulling the cutting wire from the handheld component toward the connecting assembly.
[0016] Alternatively, the power storage assembly includes a reel frame, a reel, a torsion spring, an intermediate disc, and a pin. Part of the cutting wire is wound around the reel. The reel frame is mounted on the connecting assembly. The reel and the intermediate disc are rotatably mounted on the reel frame. The pin is disposed between the reel frame and the intermediate disc to lock the intermediate disc onto the reel frame. The pin can be pulled out from between the reel frame and the intermediate disc to allow the intermediate disc to rotate relative to the reel frame. The reel frame has a shaft, and the torsion spring is sleeved on the shaft. The torsion spring has two connectors, one of which connects to the reel, and the other connects to the intermediate disc. The torsion spring is configured such that, during the cutting... When the cutting wire is pulled from the connecting assembly toward the handheld component and the intermediate disc is locked onto the wheel frame, the cutting wire drives the thread reel to rotate relative to the intermediate disc. Under the drive of the thread reel, the thread reel is twisted and deformed to generate elastic force for energy storage. When the power assembly releases the cutting wire and the intermediate disc is locked onto the wheel frame, the elastic force causes the thread reel to reverse, thereby pulling the cutting wire from the handheld component toward the connecting assembly. The thread reel is configured to rotate and drive the torsion spring and the intermediate disc to rotate relative to the wheel frame after the pin is pulled out from between the wheel frame and the intermediate disc, and when the cutting wire is pulled from the connecting assembly toward the handheld component, in order to release the cutting wire.
[0017] In some embodiments, the reel carrier is rotatably connected to the connecting assembly.
[0018] In some embodiments, the power assembly includes a reciprocating member and a driving member, the reciprocating member having a first wire-threading hole, and the driving member and the reciprocating member being driven to drive the reciprocating member to reciprocate.
[0019] The handheld component has a through-hole that connects the interior and exterior of the handheld component. The cutting wire includes a fixed section, an adjusting section, and a through-hole. The adjusting section passes through the first wire-threading hole. Both the fixed section and the adjusting section are located in the handheld component. The fixed section is located on one side of the adjusting section and is fixed to the handheld component. The through-hole is located on the other side of the adjusting section. The through-hole extends out of the handheld component through the through-hole to connect to the connecting assembly.
[0020] When the handheld component drags the cutting wire relative to the adhesive, the adjusting segment is tightened, and the portion of the tightened adjusting segment passing through the first wire-threading hole abuts against the inner wall of the first wire-threading hole. The reciprocating component is configured to reciprocate to periodically adjust the direction of the tightened adjusting segment through the first wire-threading hole. The direction of the tightened adjusting segment includes a straight line and a zigzag line. During the process of adjusting the tightened adjusting segment from a straight line to a zigzag line, the cutting wire is pulled. During the process of adjusting the tightened adjusting segment from a zigzag line to a straight line, the cutting wire is released.
[0021] In some embodiments, a wire pressing assembly is also included, wherein the cutting wire cooperates with the wire pressing assembly, and the wire pressing assembly is used to press the portion of the cutting wire near the adhesive close to the glass;
[0022] The wire pressing assembly includes a base and a rotating shaft. The base is used to connect with the glass, and the rotating shaft is rotatably mounted on the base. The rotating shaft has a second wire-passing hole through which the cutting wire passes.
[0023] Alternatively, the wire pressing assembly includes a rotating shaft, a guide rod, and a slider. The guide rod is used to connect the glass or the guide rod is detachably connected to the connecting assembly. The guide rod has a groove, the slider is slidably connected in the groove, the rotating shaft is rotatably disposed on the slider, and the rotating shaft has a second wire-passing hole through which the cutting wire passes.
[0024] In some embodiments, the connecting assembly includes a connecting frame, a suction cup, a safety rope, and a hook safety buckle. The suction cup is disposed on the connecting frame for adhering the connecting frame to the glass. One end of the safety rope is connected to the connecting frame, and the other end of the safety rope is connected to the hook safety buckle.
[0025] This application provides a glass dismantling device that uses a heater to heat a cutting wire. Workers can apply external force by holding a handpiece and dragging the cutting wire relative to the adhesive to cut the adhesive and dismantle the glass. Firstly, compared to breaking glass with a hammer, this device exerts very little or no impact on the glass, thus reducing the likelihood of deformation of the mounting part. Secondly, the heated cutting wire softens or even melts the adhesive through high temperature, reducing cutting resistance and significantly decreasing the force acting on the glass. This further reduces the risk of deformation of the mounting part and improves the cutting efficiency of the adhesive, thereby increasing the efficiency of glass dismantling.

[0046] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation
[0047] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.
[0048] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0049] In this application, the terms "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.
[0050] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, article, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, article, or apparatus.
[0051] Trains are an important means of transportation. They contain various types of glass, including windshields, door windows, and window panes, which are secured to mounting points on the train using adhesive. During train maintenance, it is necessary to remove the windshields, door windows, or window panes to be replaced.
[0052] In existing technology, the glass is removed from the train by breaking it with a hammer.
[0053] However, using a hammer to break the glass during disassembly can easily cause deformation of the installation part.
[0054] For example, for rectangular glass, the outline of its corresponding mounting part is also rectangular. When disassembling by breaking the glass with a hammer, firstly, the four sides of the rectangle are prone to bending and deformation, which in turn changes the length and / or width dimensions of the mounting part, affecting the installation of the new glass; secondly, the mounting part is also prone to deformation in the glass thickness direction, which will also affect the installation of the new glass.
[0055] It should be noted that because the train's glass is relatively thick, the adhesive used for bonding it is also thick, and a adhesive cutter cannot easily cut through this thick adhesive. Therefore, an adhesive cutter is not used to remove the train's glass.
[0056] Furthermore, the rubber cutter is also unsuitable for cutting adhesives with irregular cross-sectional shapes. For example, refer to... Figure 2When the cross-section of the adhesive 220 is an irregular shape with a right angle, the adhesive cutter cannot even cut through the irregularly shaped adhesive 220.
[0057] Regarding the above issues, refer to... Figure 1 and Figure 2 This application provides a glass disassembly device, comprising: a cutting wire 100 for passing through a connecting adhesive 220 fixing a glass 210; a connecting assembly 300 for connecting the glass 210; a handheld component 400 connected to the connecting assembly 300 via the cutting wire 100; the handheld component 400 being configured to drag the cutting wire 100 relative to the connecting adhesive 220 under the action of an external force to cut the connecting adhesive 220; and a heater 500 connected to the cutting wire 100 to heat the cutting wire 100.
[0058] Before using a glass removal device to remove the glass, a needle, awl, or even drill is used to poke or drill holes in the adhesive 220 for the cutting wire 100 to pass through. The cutting wire 100 is then passed through these holes into the adhesive 220. The cutting wire 100 is heated by a heater 500, and the operator can apply external force by holding the handpiece 400 and dragging the cutting wire 100 relative to the adhesive 220 to cut the adhesive 220 and remove the glass 210. In this process, firstly, compared to breaking glass by hammering, the impact force of this application on the glass 210 is very small or even non-existent, so it is not easy to deform the mounting part; then, the heated cutting line 100 softens or even melts the adhesive 220 through high temperature, which helps to reduce the cutting resistance of the adhesive and can significantly reduce the force acting on the glass 210 (it should be noted that the greater the force, the greater the risk of deformation of the mounting part), which helps to further reduce the risk of deformation of the mounting part and can also improve the cutting efficiency of the adhesive, thereby improving the disassembly efficiency of the glass.
[0059] For example, the cutting wire 100 is detachable from the connecting assembly 300; or the cutting wire 100 is detachable from the handpiece 400; so that the cutting wire 100 passes through the hole in the connecting adhesive 220.
[0060] The cutting wire 100 can be a metal wire with good thermal conductivity, for example, it can be a single strand of steel wire or a steel wire rope made of multiple strands of steel wire. Abrasives (such as diamond particles) can also be attached to the surface of the single strand of steel wire or the steel wire rope to further enhance the cutting effect. When the cutting wire 100 is a metal wire with good thermal conductivity, the heater 500 only needs to be able to generate heat and conduct the heat to the metal wire to heat the metal wire.
[0061] The cutting wire 100 can also be a folded and twisted enameled heating wire. In this case, the heater 500 is a power supply device. The heater 500 is connected to the two poles of the enameled heating wire to supply power, and the heating effect of the current causes the enameled heating wire to heat up. After the folded and twisted enameled heating wire passes through the connecting adhesive, its two poles are located on the same side of the glass, which facilitates power supply to the enameled heating wire during the cutting of the connecting adhesive.
[0062] The heater 500 can be equipped with a temperature controller to control the temperature of the cutting wire 100, so as to prevent open flames from being generated during the glass dismantling operation due to excessive temperature, thus ensuring fire safety.
[0063] For example, the handpiece 400 has a heat-insulated handle 440, which an operator can use to drag the handpiece to apply the external force required to cut the adhesive 220.
[0064] The connecting component 300 only needs to be able to be connected to one side of the glass being disassembled. It can be connected to one side of the glass by adhesive; or a hole can be drilled in the glass and then the connecting component can be connected to the glass by bolts; the connecting component 300 may also include a suction cup, which is used to connect to the glass.
[0065] In some implementations, refer to Figure 1 The heater 500 includes a metal block 510 and an electromagnetic induction component 520. The metal block 510 is connected to the cutting line 100. The electromagnetic induction component 520 and the metal block 510 cooperate. Under the principle of electromagnetic induction, the electromagnetic induction component 520 generates eddy currents in the metal block 510 to heat the metal block 510. The metal block 510 is used to conduct heat to the cutting line 100.
[0066] It should be noted that because the train windows are all sealed, during maintenance work, it is difficult to route one pole or phase inside the train and the other pole or phase outside by wiring the power supply used for maintenance. This also makes it difficult to provide power to both sides of the glass being removed. (Refer to...) Figure 1 and Figure 3 After the cutting wire 100 passes through the connecting adhesive 220, the heater 500 can be powered on one side of the glass 210 to heat the cutting wire 100.
[0067] It should be noted that, referring to Figure 1The electromagnetic induction component 520 is a prior art technology that uses the principle of electromagnetic induction to directly convert electrical energy into internal heat energy of a heated object (metal block 510 in this application). The electromagnetic induction component 520 includes an electromagnetic induction coil 522 and a module for supplying and / or controlling high-frequency alternating current to the electromagnetic induction coil. In the embodiments of this application, the module for supplying and / or controlling high-frequency alternating current to the electromagnetic induction coil is a host 521.
[0068] For example, refer to Figure 1 The electromagnetic induction component 520 includes a main unit 521 and an electromagnetic induction coil 522. The metal block 510 and the electromagnetic induction coil 522 are disposed within the handheld component 400. During the cutting of the connecting adhesive 220, the handheld component 400 is positioned as close as possible to the connecting adhesive 220, and the connecting adhesive is cut using the portion of the cutting line 100 close to the heated metal block 510, thus ensuring a good cutting effect. The main unit 521 is located outside the handheld component 400. Furthermore, the handheld component 400 has a first mounting box portion 410, in which a heat insulation block 411 is fixed. The heat insulation block 411 has a receiving cavity, within which a first support 413 and a second support are provided. The metal block 510 is cylindrical and is fixed in the receiving cavity of the heat insulation block 411 by the first bracket 413. The first bracket also supports the metal block 510 a certain distance away from the bottom of the receiving cavity of the heat insulation block 411, thereby providing a certain space for the electromagnetic induction coil 522 to be wound around it. The electromagnetic induction coil 522 is arranged around the metal block 510 but does not contact the metal block 510, and is fixed in the receiving cavity of the heat insulation block 411 by the second bracket. A first cover 412 is detachably connected to the first mounting box 410 for sealing the receiving cavity of the heat insulation block 411. The first cover 412 is made of heat-insulating material or has a heat-insulating layer.
[0069] Furthermore, referring to Figure 1 and Figure 2The metal block 510 has a spiral groove 511, which surrounds the circumferential side of the metal block 510. The cutting line 100 includes a fixing section 110, a portion of which spirally surrounds the metal block 510 via the spiral groove 511 to improve heat conduction. The first bracket 413 includes a supporting part and a pressing part. The supporting part is fixed in the heat insulation block 411, and the pressing part is detachably connected to the supporting part and forms a clamping opening between the supporting part and the pressing part. Each end of the metal block 510 is fixed by a first bracket 413. The first bracket 413 clamps the end of the metal block 510 and a portion of the fixing section 110 in the clamping opening, fixing the metal block 510 and the fixing section 110 to the metal block 510 at the same time. The fixing section 110 can also be fixed by welding a metal block 510; or, a threaded hole is provided on the metal block 510, and a screw is connected to the threaded hole. The screw is used to press part of the fixing section 110 onto the metal block 510 to fix the fixing section 110 onto the metal block 510.
[0070] In some implementations, refer to Figure 1 The glass removal device also includes a reciprocating mechanism 600 connected to the cutting line 100; the reciprocating mechanism 600 is configured to periodically pull the cutting line 100 back and forth between the handpiece 400 and the connecting assembly 300.
[0071] Understandably, during the cutting process of the connecting adhesive 220, debris or melted portions of the connecting adhesive 220 may adhere to the portion of the cutting wire 100 that passes through the connecting adhesive 220. Excessive adhesion could negatively impact the subsequent thermal cutting effect. The reciprocating mechanism 600 periodically pulls the cutting wire 100 back and forth between the handheld component 400 and the connecting assembly 300. This increases the frequency of the cutting wire 100's movement relative to the connecting adhesive 220 in the direction the cutting wire 100 passes through the connecting adhesive 220, facilitating the removal of these debris and / or melted portions from the surface of the cutting wire 100, especially from the portion where the cutting wire 100 passes through the connecting adhesive 220, further ensuring the effectiveness of thermal cutting. Furthermore, for cutting wires 100 with abrasive or rough surfaces, the reciprocating pull of the cutting wire 100 by the reciprocating mechanism 600 creates a "sawing" effect on the connecting adhesive 220, further improving the cutting efficiency of the connecting adhesive and thus increasing the efficiency of glass disassembly.
[0072] In some implementations, refer to Figure 1The reciprocating mechanism 600 includes a power component 610 and a power storage component 620. The power component 610 is disposed in the handheld component 400, and the power storage component 620 is disposed on the connecting component 300. The cutting wire 100 connects the power component 610 and the power storage component 620. The power component 610 is used to periodically pull and release the cutting wire 100. When the power component 610 pulls the cutting wire 100, it pulls the cutting wire 100 from the connecting component 300 to the handheld component 400. The power storage component 620 is configured to store power when the cutting wire 100 is pulled from the connecting component 300 to the handheld component 400, and when the power component 610 releases the cutting wire 100, it uses the stored power to pull the cutting wire 100 from the handheld component 400 to the connecting component 300.
[0073] Understandably, when the power component 610 pulls the cutting wire 100, the cutting wire 100 is pulled from the connecting component 300 to the handheld component 400, while the power storage component 620 stores energy. When the power component 610 releases the cutting wire 100, the stored force is used to pull the cutting wire 100 from the handheld component 400 back to the connecting component 300; this is how the reciprocating pulling operation of the cutting wire 100 is performed.
[0074] For example, the power assembly 610 is disposed on one of the connecting assembly 300 and the handheld part 400, and the power storage assembly 620 is disposed on the other of the connecting assembly 300 and the handheld part 400.
[0075] In some embodiments, the power storage component 620 is a tension spring, with one end connected to the connecting component 300 and the other end connected to the cutting wire 100. The tension spring is configured such that when the cutting wire 100 is pulled from the connecting component 300 to the handheld component 400, it is stretched by the cutting wire 100 to generate elastic force for power storage. When the power component 610 releases the cutting wire 100, the elastic force pulls the cutting wire 100 from the handheld component 400 to the connecting component 300. It should be noted that the embodiment of the power storage component 620 as a tension spring is not shown in a separate accompanying drawing. It is understood that using a tension spring as the power storage component 620 has two advantages: its simple structure and the flexibility of the tension spring, which facilitates easy adjustment of its orientation to accommodate changes in the orientation of the cutting wire 100.
[0076] In some implementations, refer to Figure 1 , Figure 6 and Figure 7As shown, the power storage assembly 620 includes a reel frame 621, a reel 622, a torsion spring 623, an intermediate disc 624, and a pin 625. A portion of the cutting wire 100 is wound around the reel 622. The reel frame 621 is mounted on the connecting assembly 300, and the reel 622 and the intermediate disc 624 are rotatably mounted on the reel frame 621. The pin 625 is disposed between the reel frame 621 and the intermediate disc 624 to lock the intermediate disc 624 onto the reel frame 621; the pin 625 can be pulled out from between the reel frame 621 and the intermediate disc 624, allowing the intermediate disc 624 to rotate relative to the reel frame 621. The reel frame 621 has a shaft portion 6211, and the torsion spring 623 is sleeved on the shaft portion 6211. The torsion spring 623 has two connectors, one connecting to the reel 622 and the other connecting to the intermediate disc 624. The torsion spring 623 is configured such that, when the cutting wire 100 is pulled from the connecting assembly 300 to the handheld member 400 and the intermediate disc 624 is locked onto the reel frame 621, the cutting wire 100 drives the reel 622 to rotate relative to the intermediate disc 624. Driven by the reel 622, the reel is twisted and deformed to generate elastic force for energy storage. When the power assembly 610 releases the cutting wire 100 and the intermediate disc 624 is locked onto the reel frame 621, the elastic force causes the reel to reverse, thereby pulling the cutting wire 100 from the handheld member 400 to the connecting assembly 300. The reel 622 is configured such that, after the pin 625 is pulled out from between the reel frame 621 and the intermediate disc 624, and when the cutting wire 100 is pulled from the connecting assembly 300 to the handheld member 400, it rotates and drives the torsion spring 623 and the intermediate disc 624 to rotate relative to the reel frame 621, thereby unloading the cutting wire 100.
[0077] It should be noted that, without adjusting the connection position of the connecting component 300 on the glass, it is sometimes necessary to adjust the length of the portion of the cutting line 100 located between the connecting component 300 and the handheld component 400 to ensure the cutting effect.
[0078] For example, when the outline of the glass to be disassembled is a rectangle with a large aspect ratio, when cutting different positions with a large span of the outline, the length of the portion of the cutting line 100 between the connecting component 300 and the handle 400 needs to be adjusted to avoid the handle 400 being too far from the connecting adhesive 220 or to avoid the cutting line 100 being too short between the connecting component 300 and the handle 400.
[0079] Alternatively, in confined spaces, the length of the section of the cutting line 100 between the connecting component 300 and the handheld component 400 can be adjusted so that the handheld component 400 is as close as possible to the connecting adhesive 220 or the glass 210, thus facilitating operations in confined spaces.
[0080] Understandably, when it is necessary to adjust the length of the section of the cutting wire 100 located between the connecting assembly 300 and the handheld piece 400, the pin 625 can be pulled out from between the reel frame 621 and the intermediate disc 624. Then, the cutting wire 100 can be pulled from the connecting assembly 300 toward the handheld piece 400, causing the reel 622 to rotate and drive the torsion spring 623 and the intermediate disc 624 to rotate relative to the reel frame 621, thereby releasing a certain length of the cutting wire 100. Alternatively, the reel 622 can be rotated in the opposite direction to retract a certain length of the cutting wire. After adjustment, the intermediate disc 624 is locked onto the reel frame 621 by the pin 625 to continue the cutting of the connecting adhesive 220.
[0081] For example, refer to Figure 7 and Figure 8 The pin 625 includes a round rod, at least partially having external threads. The reel frame 621 has a hole through which the round rod passes, and the hole has an internal thread that mates with the external threads on the round rod. The round rod is threadedly connected to the hole to prevent the pin 625 from falling off without external force while the intermediate disc 624 is locked to the reel frame 621. The intermediate disc 624 has a plurality of pin holes 6241 arranged in a circumferential array. By rotating the intermediate disc 624 relative to the reel frame 621, different pin holes are aligned with the round rod passing through the holes on the reel frame 621. After the round rod passing through the holes on the reel frame 621 is aligned and inserted into the aligned pin holes 6241, the intermediate disc 624 is locked to the reel frame 621.
[0082] In some implementations, refer to Figure 9 As another structure of the power storage component 620, the power storage component 620 includes a reel frame 621, a reel 622, and a torsion spring 623. The reel frame 621 is mounted on the connecting component 300, the reel 622 is rotatably mounted on the reel frame 621, a portion of the cutting wire 100 is wound around the reel 622, the reel frame 621 has a shaft portion 6211, and the torsion spring 623 is sleeved on the shaft portion 6211. The torsion spring 623 has two connectors, one of which connects to the reel 622 and the other connects to the reel holder 621. The torsion spring 623 is configured such that when the cutting wire 100 is pulled from the connecting assembly 300 to the handheld member 400, the cutting wire 100 drives the reel 622 to rotate clockwise relative to the reel holder 621, and the reel 622 twists and deforms under the drive of the cutting wire 100 to generate elastic force for energy storage. When the power assembly 610 releases the cutting wire 100, the elastic force causes the reel 622 to rotate counterclockwise relative to the reel holder 621, so as to pull the cutting wire 100 from the handheld member 400 to the connecting assembly 300.
[0083] Understandably, when the cutting wire 100 is pulled from the connecting assembly 300 to the handheld component 400, the cutting wire 100 drives the reel 622 to rotate clockwise relative to the reel frame 621. The torsion spring 623, driven by the reel 622, twists and deforms to generate elastic force for power storage. When the power assembly 610 releases the cutting wire 100, the elastic force causes the reel 622 to rotate counterclockwise relative to the reel frame 621, thus pulling the cutting wire 100 from the handheld component 400 to the connecting assembly 300. The advantage of this power storage assembly structure is that, compared to a tension spring solution, it can store power even in spaces with limited depth.
[0084] In some implementations, refer to Figure 1 , Figure 3 and Figure 6 The reel holder 621 is rotatably connected to the connecting assembly 300. Understandably, as the cutting wire 100 moves relative to the connecting adhesive 220, the orientation of the cutting wire 100 may also change, and the reel holder 621 is positioned relative to the connecting assembly 300 to accommodate this change in the orientation of the cutting wire 100.
[0085] For example, refer to Figure 1 and Figure 6 The connecting assembly 300 has a rotating shaft that connects to the inner ring of the bearing and the outer ring of the bearing that connects to the reel carrier 621, so as to rotatably connect the reel carrier 621 to the connecting assembly.
[0086] In some implementations, refer to Figure 1The power assembly 610 includes a reciprocating member 612 and a driving member 611. The reciprocating member 612 has a first wire-passing hole 6123. The driving member 611 and the reciprocating member 612 are connected for driving the reciprocating member 612 to move back and forth. The handheld member 400 has a through hole 451 that connects the interior and exterior of the handheld member 400. The cutting wire 100 includes a fixed section 110, an adjusting section 120, and a through section 130. The adjusting section 120 passes through the first wire-passing hole 6123. Both the fixed section 110 and the adjusting section 120 are located in the handheld member 400. The fixed section 110 is located on one side of the adjusting section 120 and is fixed to the handheld member 400. The through section 130 is located on the other side of the adjusting section 120 and passes through the through hole 451 from the handheld member 400 for connecting to the connecting assembly 300. When the handheld component 400 drags the cutting wire 100 relative to the connecting adhesive 220, the adjusting section 120 is tightened, and the portion of the tightened adjusting section 120 passing through the first wire-threading hole 6123 abuts against the inner wall of the first wire-threading hole 6123. The reciprocating component 612 is configured to reciprocate to periodically adjust the orientation of the tightened adjusting section 120, which includes a straight orientation and a zigzag orientation. During the process of adjusting the tightened adjusting section 120 from a straight orientation to a zigzag orientation, the cutting wire 100 is pulled; during the process of adjusting the tightened adjusting section 120 from a zigzag orientation to a straight orientation, the cutting wire 100 is released.
[0087] Understandably, when the adjustment section 120 is taut, the power assembly 610 can periodically pull and release the cutting wire by reciprocating the reciprocating movement of the reciprocating member 612.
[0088] For example, refer to Figure 1 , Figure 4 and Figure 5The handheld component 400 has a first mounting box portion 410 and a second mounting box portion 420. A fixing section 110 is fixed to a metal block 510, which is fixed within the receiving cavity of a heat-insulating block 411 in the first mounting box portion 410. The first mounting box portion 410 and the second mounting box portion 420 are separated by a section of the side wall of the heat-insulating block 411 to provide a certain degree of heat insulation. A driving component 611 is disposed in the first mounting box portion 410, which reduces the impact of heat on the driving component 611 to some extent. The driving component 611 is connected to a reciprocating component 612 via a cam 613. The reciprocating component 612 has a slider portion 6121 and a rod portion 6122. A sliding block 430 is provided in the first mounting box 410. The outer contour of the sliding block 430 is cuboid. The sliding block 430 has a through hole 431 for a bolt. The second mounting box 420 has an internal threaded part aligned with the through hole. A bolt passes through the through hole 431 and is connected to the aligned internal threaded part to fix the sliding block 430 in the second mounting box 420. The sliding block 430 has a sliding cavity. A slider 6121 is slidably connected in the sliding cavity to slide through the sliding block 430. A rod 6122 extends out from the bottom of the sliding cavity. A compression spring 614 is sleeved on the rod 6122. The upper end of the compression spring 614 abuts against the lower end of the slider 6121, and the lower end of the compression spring 614 abuts against the bottom of the sliding cavity. The compression spring 614 is used to press the slider 6121 against the cam 613. The heat insulation block 411 has a hole for the rod 6122 to pass through, the rod 6122 is inserted into the receiving cavity of the heat insulation block 411, and the first wire-threading hole 6123 is provided on the rod 6122 and located in the receiving cavity of the heat insulation block.
[0089] For example, a second cover 421 is detachably connected to the second mounting box portion 420 to close the inner cavity of the second mounting box portion 420.
[0090] For example, two pulleys can be provided at the end of the rod 6122 to replace the first wire-threading hole 6123, and the cutting wire 100 passes between the two pulleys. The pulleys can reduce the wear on the cutting wire 100.
[0091] For example, the handheld component 400 has a cable guide 450 through which the through hole 451 passes.
[0092] In some implementations, refer to Figure 2The glass removal device also includes a wire pressing assembly 700. A cutting wire 100 cooperates with the wire pressing assembly 700, which is used to press the portion of the cutting wire 100 near the connecting adhesive 220 close to the glass 210. It should be noted that when the connecting assembly 300 is close to the cutting position of the connecting adhesive 220 and the connecting assembly 300 raises the cutting wire 100 to a certain height, the angle of inclination of the portion of the cutting wire 100 near the mounting part 200 relative to the glass is easily large, thus the cutting wire 100 is prone to squeezing the mounting part 200; or, due to space limitations in the working environment, it is difficult to adjust the angle of inclination of the cutting wire 100 near the mounting part 200 by adjusting the position of the handheld component 400, the cutting wire 100 is also prone to squeezing the mounting part 200. This application uses the wire pressing assembly 700 to press the portion of the cutting wire 100 near the connecting adhesive 220 close to the glass 210, thereby preventing the cutting wire from squeezing the mounting part 200 and protecting the mounting part 200.
[0093] Reference Figure 2 and Figure 10 As a structure of the wire pressing assembly 700, the wire pressing assembly 700 includes a base 710 and a rotating shaft 720. The base 710 is used to connect with the glass 210, and the rotating shaft 720 is rotatably mounted on the base 710. The rotating shaft 720 has a second wire-passing hole 721 through which the cutting wire 100 passes.
[0094] For example, a magnet 711 is provided on the base 710, and a magnet that cooperates with the magnet 711 is provided on the other side of the glass 210 to connect the base to the glass 210.
[0095] For example, a suction cup may also be provided on the base 710 to connect the base 710 to the glass.
[0096] Reference Figure 11 and Figure 12 As another structure of the wire pressing assembly 700, the wire pressing assembly 700 includes a rotating shaft 720, a guide rod 730, and a slider 740. The guide rod 730 is used to connect glass or is detachably connected to a connecting assembly. The guide rod 730 has a groove 731, and the slider 740 is slidably connected in the groove 731. The rotating shaft 720 is rotatably mounted on the slider 740. The rotating shaft 720 has a second wire-passing hole 721 through which the cutting wire 100 passes.
[0097] For example, the overall outline of the glass to be disassembled is rectangular, and its outline includes two sides in a first direction and two sides in a second direction. When cutting the adhesive on one side in one of the directions, the guide rod 730 is connected to the glass or connecting assembly, and the groove 731 is made approximately parallel to the direction of that side; thus, when the cutting line 100 is dragged to cut the corresponding adhesive in that direction, the slider 740 slides accordingly along the groove 731, which helps to keep the pressure direction of the cutting line 100 on the adhesive to be cut approximately consistent with the direction of continuous cutting.
[0098] For example, the guide rod 730 may be equipped with a suction cup for attaching to the glass; a magnet may also be provided on the guide rod 730, with a magnet cooperating with the magnet on the other side of the glass to attach it to the glass. A clamp for detaching the guide rod 730 may also be provided on the connecting assembly to detachably attach the guide rod 730 to the connecting assembly.
[0099] For example, refer to Figure 11 Multiple guide rods 730 can be spliced together along their length. Each guide rod 730 has a threaded hole 732 at both ends. When two guide rods 730 need to be spliced together along their length, bolts are connected through the threaded holes 732. These bolts are used to connect the plate, thereby splicing adjacent guide rods 730 into one piece.
[0100] In some implementations, refer to Figure 1 The connecting assembly 300 includes a connecting frame 310, a suction cup 320, a safety rope 330, and a hook safety buckle 340. The suction cup 320 is disposed on the connecting frame 310 for adsorbing the connecting frame 310 onto the glass 210. One end of the safety rope 330 is connected to the connecting frame 310, and the other end of the safety rope 330 is connected to the hook safety buckle 340.
[0101] Understandably, using suction cup 320 to attach the connecting bracket 310 to the glass 210 facilitates the quick assembly and disassembly of the connecting component 300 on the glass, improving work efficiency and enabling reuse. After the connecting component 300 is connected to the glass, another hook safety buckle can be suspended at a suitable location on the train (e.g., the train's luggage rack). The hook safety buckle 340 is then connected to another hook safety buckle installed on the train to prevent the connecting component 300 from falling off the glass and damaging facilities inside the train.
[0102] For example, refer to Figure 1There are multiple suction cup components 320; each suction cup component 320 includes a suction cup rod 321 and a suction cup head 322 disposed at the end of the suction cup rod 321. The suction cup rod 321 is threadedly connected to the connector 310. The suction cup rod 321 is rotated relative to the connector 310 to adjust the distance between the suction cup head 322 and the connector 310, so as to facilitate the adjustment of the plane on which each suction cup head 322 is located, thereby making the position of each suction cup head 322 suitable for some curved glass.
