Description

Technical Field

[0001] This application relates to the field of forklift counterweight maintenance, and in particular to a high-temperature firing maintenance device for forklift counterweights and its usage method. Background Technology

[0002] Counterweights are an important component of forklifts. Their main function is to ensure the longitudinal and lateral stability of the vehicle, making it less likely for the vehicle to tilt during use.

[0003] The counterweight is mainly made of low-alloy high-strength Cr-Mo steel. After casting, the counterweight needs to be cooled. However, if the counterweight is cooled directly indoors, the surface of the counterweight is prone to peeling during the cooling process. To improve the quality of the finished counterweight, it needs to be stored at a constant temperature after melting.

[0004] In related technologies, heat insulation covers are typically used for heat preservation storage of counterweights. The inner wall of the heat insulation cover is lined with insulating cotton, primarily made of asbestos, to keep the counterweights at high temperatures after smelting. When heat preservation storage of counterweights is required, the size of the heat insulation cover must be selected according to the number of counterweights. However, the internal dimensions of the heat insulation cover are not always perfectly suited to all counterweights; gaps exist between each counterweight and the heat insulation cover, which can affect the heat preservation effect of the cover on each counterweight. Therefore, this aspect needs improvement. Summary of the Invention

[0005] To address the aforementioned issues, this application provides a high-temperature firing and curing device for forklift counterweights and its usage method.

[0006] Firstly, this application provides a high-temperature firing and curing device for forklift counterweights, which adopts the following technical solution:

[0007] A high-temperature firing and curing device for forklift counterweights includes a heat insulation cover and a heating component. The heating component includes several moving blocks and heating wires, with each heating wire correspondingly connected to a moving block. The inner wall of the heat insulation cover has several moving grooves, which are evenly distributed and arranged along the diagonal of the heat insulation cover. A screw is rotatably connected to each moving groove. The moving blocks are slidably connected to their corresponding moving grooves and threadedly connected to their corresponding screws. Several heat-conducting plates are rotatably connected to the heat insulation cover. The heat insulation cover is equipped with a synchronization component for synchronously controlling the rotation of each screw. The synchronization component is connected to the heat-conducting plates through a connecting component, which controls the rotation of the heat-conducting plates.

[0008] By adopting the above technical solution, when the counterweights need to be kept warm, workers cover each counterweight with an insulation cover, and then activate the synchronization component according to the number of counterweights. The synchronization component controls the synchronous rotation of each screw, and under the limiting action of the moving slot, the moving block moves along the corresponding moving slot. The moving block then drives the heating wire to move, changing the position of the heating wire so that the heating wire can more concentratedly insulate each counterweight. During the operation of the synchronization component, the synchronization component drives the connecting component to start, and the connecting component then drives the heat-conducting plate to start, causing the heat-conducting plate to rotate towards the heating wire. At this time, the heat-conducting plate can guide the heat dissipated by the heating wire, so that the heat of the heating wire can be transferred to each counterweight more stably, thereby improving the insulation effect of each counterweight, reducing the possibility of peeling during the insulation process, and thus improving the final molding quality of each counterweight.

[0009] Preferably, the synchronization assembly includes a synchronization rod and a synchronization gear. A synchronization cavity is formed in the heat insulation cover, and a synchronization groove communicating with the synchronization cavity is formed on the heat insulation cover. The synchronization rod is rotatably connected in the synchronization groove and extends into the synchronization cavity. The synchronization gear is coaxially disposed on the synchronization rod located in the synchronization cavity. Each of the moving grooves is connected to the synchronization cavity. Each of the screws extends into the synchronization cavity and is coaxially connected to a mating gear. Each of the mating gears meshes with the synchronization gear.

[0010] By adopting the above technical solution, when it is necessary to synchronously control the movement of each heating wire, the worker controls the synchronous rod to rotate, the synchronous rod drives the synchronous gear to rotate, the synchronous gear drives each mating gear to rotate, and each mating gear drives the corresponding screw to rotate. At this time, the screw can move each moving block, thus realizing the function of synchronously controlling the movement of each heating wire.

[0011] Preferably, the connecting assembly includes a first synchronous pulley, a second synchronous pulley, and a synchronous toothed belt. The first synchronous pulley is coaxially mounted on a synchronous rod located in the synchronous cavity. The heat insulation cover has a first connecting cavity communicating with the synchronous cavity. The second synchronous pulley is rotatably connected in the first connecting cavity. The synchronous toothed belt is wound around the first and second synchronous pulleys. Both the first and second synchronous pulleys mesh with the synchronous toothed belt. A gear set is provided on the shaft of the second synchronous pulley. The side of the gear set away from the second synchronous pulley is connected to the shaft of the heat-conducting plate.

[0012] By adopting the above technical solution, during the rotation of the synchronizing rod, the synchronizing rod drives the first synchronizing pulley to rotate, the first synchronizing pulley drives the synchronizing toothed belt to rotate, the synchronizing toothed belt then drives the second synchronizing pulley to rotate, the second synchronizing pulley drives the gear set to start, and the gear set then drives the corresponding heat-conducting plate to rotate. At this time, the heat-conducting plate can change its inclination according to the concentration of each heating wire, so that the heat-conducting plate can more stably conduct the heat of the heating wire to each counterweight, thereby improving the heat preservation effect of the maintenance device on each counterweight.

[0013] Preferably, the inner wall of the heat insulation cover is provided with a plurality of clearance grooves, the inner wall of the clearance grooves is provided with guide grooves, an adjusting rod is slidably connected in the guide grooves, a first heat insulation frame and a second heat insulation frame are rotatably connected on the adjusting rod, each heat-conducting plate corresponds to a set of first heat insulation frames and second heat insulation frames, and heat insulation plates are provided on the first heat insulation frames and second heat insulation frames. The heat insulation cover is provided with a control cavity, and the control cavity is provided with a control component for controlling the movement of the adjusting rod. The end of the control component away from the adjusting rod is connected to the corresponding heat-conducting plate.

[0014] By adopting the above technical solution, during the rotation of the heat-conducting plate, the heat-conducting plate drives the control component to start, and the control component controls the adjusting rod to move along the guide groove. During the movement of the adjusting rod, due to the limiting effect of the clearance groove, the movement of the adjusting rod can drive the first heat insulation frame and the second heat insulation frame to rotate in opposite directions, so that the first heat insulation frame and the second heat insulation frame are in an inclined state. At this time, the heat insulation plates on the first heat insulation frame and the second heat insulation frame insulate the heat of each heating wire and each counterweight, reducing the possibility of heat conduction from inside the heat insulation cover to the outside, thereby further improving the heat insulation capacity of the heat insulation cover for each counterweight.

[0015] Preferably, the control assembly includes a first pulley, a second pulley, a third pulley, a control plate, and a pull rope. The first pulley, the second pulley, and the third pulley are all rotatably connected in the control cavity. The heat insulation cover has a through hole for connecting the relief groove and the control cavity. The control plate is slidably connected in the through hole. The pull rope is sequentially wound around the first pulley, the second pulley, and the third pulley. One end of the pull rope extends out of the control cavity and is connected to the heat-conducting plate, and the other end is connected to the control plate. The end of the control plate away from the pull rope is connected to the adjusting rod through a mating rod.

[0016] By adopting the above technical solution, during the rotation of the heat-conducting plate, the heat-conducting plate drives one end of the pull rope to move. The pull rope sequentially drives the first pulley, the second pulley, and the third pulley to rotate, thereby increasing the prestress inside the pull rope. The other end of the pull rope then drives the control plate to move. The control plate moves one end of the connecting rod, and the other end of the connecting rod drives the control rod to move along the guide groove. This allows the control rod to control the first and second heat insulation frames to rotate in opposite directions, thus isolating the heat from each heating wire and each counterweight.

[0017] Preferably, the inner wall of the heat preservation cover is rotatably connected with a plurality of heat recovery plates, each heat recovery plate corresponding to a heat conduction plate. The heat recovery plates and the corresponding heat conduction plates are arranged opposite to each other. The control cavity is provided with an adjustment component for controlling the rotation of the heat recovery plates. One end of the adjustment component cooperates with the control plate and the other end cooperates with the heat recovery plate.

[0018] By adopting the above technical solution, during the movement of the control plate, the control plate drives the adjustment component to start, and the adjustment component then drives the heat recovery plate to rotate, so that the heat recovery plate is opposite to each counterweight. At this time, the heat conduction plate blocks the heat emitted by the counterweight and the heating wire, further reducing the possibility of heat in the heat insulation cover being dissipated to the outside, thereby further improving the heat insulation effect of the maintenance device on each counterweight.

[0019] Preferably, the adjustment assembly includes an adjustment block and a connector. The inner wall of the control cavity is provided with an adjustment groove. The adjustment block is slidably connected in the adjustment groove. The adjustment block is provided with a first rack. The control plate is provided with a second rack. The first rack and the second rack are perpendicular to each other. The inner wall of the control cavity is rotatably connected with an adjustment gear. Both the first rack and the second rack mesh with the adjustment gear. One end of the connector is connected to the heat recovery plate, and the other end is connected to the end of the adjustment block away from the first rack.

[0020] By adopting the above technical solution, during the movement of the control plate, the control plate drives the second rack to move, the second rack drives the adjusting gear to rotate, and the adjusting gear then drives the first rack to move. Under the guidance of the adjusting groove, the first rack drives the adjusting block to move along the adjusting groove. The movement of the adjusting block drives the connecting piece to move, and the connecting piece then drives the heat recovery plate to rotate, so that the heat recovery plate blocks the heat dissipation of each counterweight and heating wire.

[0021] Preferably, the connector includes a connecting rod and a telescopic rod. The connecting rod is connected to the heat recovery plate. The end of the connecting rod away from the heat recovery plate has a telescopic groove along its length. The telescopic rod is slidably connected in the telescopic groove. The adjusting block has a sliding groove on the side away from the first rack. A slider is slidably connected in the sliding groove. The end of the telescopic rod away from the connecting rod is rotatably connected to the slider.

[0022] By adopting the above technical solution, during the movement of the adjusting block, the adjusting block drives the slider to move along the direction of the adjusting groove. Since the slider is connected to the telescopic rod, the adjusting block drives the telescopic rod to move away from the connecting rod, while the slider moves along the groove. The slider then sequentially drives the telescopic rod, connecting rod, and regenerating plate to rotate, so that the regenerating plate is opposite to each counterweight, so that the regenerating plate blocks the heat emitted by the counterweight and heating wire.

[0023] Preferably, the telescopic groove is provided with a spring, one end of which is connected to the telescopic rod and the other end is connected to the bottom of the telescopic groove.

[0024] By adopting the above technical solution, during the movement of the telescopic rod, the rod pulls the spring, which is in a stretched state. During the subsequent resetting process of the heat recovery plate, the spring's rebound force applies tension to the telescopic rod, allowing it to automatically reset.

[0025] Secondly, this application provides a method for using a high-temperature firing and curing device for forklift counterweights, employing the following technical solution:

[0026] A method for using a high-temperature firing and curing device for forklift counterweights includes the following steps:

[0027] The synchronization component controls the synchronous rotation of each screw to control the movement of each of the moving blocks and heating wires;

[0028] The synchronization component controls the connection component to start, and the connection component controls the rotation of the heat-conducting plate;

[0029] The heat-conducting plate drives the control component to start, and the control component controls the first heat insulation frame and the second heat insulation frame to rotate in opposite directions;

[0030] The control panel controls the adjustment component to start, and the adjustment component controls the rotation of the heat recovery plate so that the heat recovery plate is opposite to the heat conduction plate.

[0031] By adopting the above technical solution, when heat preservation is required for each counterweight, workers cover each counterweight with an insulation cover, and then control the synchronization component to start according to the number of counterweights. The synchronization component moves each moving block to control the concentration of each heating wire. The synchronization component drives the connecting component to start, and the connecting component controls the corresponding heat-conducting plate to rotate, so that the heat-conducting plate is opposite to the heating wire to conduct the heat emitted by the heating wire, making it easier for the heat from the heating wire to be accurately transferred to each counterweight. At the same time, the rotation of the heat-conducting plate drives the control component to start, and the control component controls the first and second heat insulation frames to rotate in opposite directions, so that the first and second heat insulation frames are in a bent state, so that the heat insulation plates on the second heat insulation frame block the heat from the heating wire and the counterweight. The control board then drives the adjustment component to start, and the heat return plate can rotate to be opposite to the heat-conducting plate, on the one hand blocking the heat from the counterweight and the heating wire, and on the other hand making the heat more concentrated on each counterweight, thereby improving the heat preservation effect of the curing device on the counterweight.

[0032] In summary, this application includes at least one of the following beneficial technical effects:

[0033] 1. By setting up a synchronization component and a connection component, the synchronization component adjusts the position of each heating wire synchronously according to the number of counterweights, changing the concentration of the heating wires. The connection component then controls the rotation of the corresponding heat-conducting plate, which guides the heat of the heating wires, so that the heat of the heating wires is transferred to each counterweight more accurately, improving the heat preservation effect of the curing device on each counterweight, thereby improving the final molding quality of each counterweight.

[0034] 2. By setting up a control component, the control component controls the first heat insulation frame and the second heat insulation frame, so that the first heat insulation frame and the second heat insulation frame are tilted, so that the heat insulation plates on the first heat insulation frame and the second heat insulation frame can more stably block the possibility of heat from the heating wire and the counterweight being conducted to the outside.

[0035] 3. By setting up a heat recovery plate, which is opposite to the heat conduction plate, the heat from the counterweight and the insulation plate is further blocked, thereby further improving the heat preservation effect of the maintenance device on the counterweight.

[0046] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0047] Firstly, this application discloses a high-temperature firing and curing device for forklift counterweights. (Refer to...) Figure 1 and Figure 2A high-temperature curing device for forklift counterweights includes a heat insulation cover 1 and a heating component 2. The heating component 2 includes several movable blocks 21 and heating wires 22, each heating wire 22 corresponding to a movable block 21 and fixed to the corresponding movable block 21. Several movable grooves 11 are formed on the inner wall of the heat insulation cover 1, and these grooves are evenly arranged along the diagonal of the heat insulation cover 1. Screws 111 are rotatably connected to the movable grooves 11, and the movable blocks 21 are slidably connected to the corresponding movable grooves 11, with the movable blocks 21 threadedly connected to the corresponding screws 111. Several heat-conducting plates 3 are rotatably connected to the heat insulation cover 1. The heat insulation cover 1 is provided with a synchronization component 12 for synchronously controlling the rotation of each screw 111. The synchronization component 12 is connected to the heat-conducting plates 3 through a connecting component 13, which controls the rotation of the heat-conducting plates 3.

[0048] Reference Figure 3 and Figure 4 The synchronization assembly 12 includes a synchronization rod 121 and a synchronization gear 122. A synchronization cavity is formed in the insulation cover 1, and a synchronization groove 14 communicating with the synchronization cavity is formed on the insulation cover 1. The synchronization rod 121 is rotatably connected in the synchronization groove 14 and extends into the synchronization cavity. The synchronization gear 122 is coaxially fixed to one end of the synchronization rod 121 located in the synchronization cavity. Each screw 111 extends into the synchronization cavity and is coaxially fixed with a mating gear 112. Each mating gear 112 meshes with the synchronization gear 122. Both the synchronization gear 122 and the mating gear 112 are bevel gears.

[0049] To facilitate the control of the synchronizing rod 121, a motor 15 is fixed on the heat insulation cover 1. A first drive wheel 151 is fixed on the output end of the motor 15. A second drive wheel 123 is coaxially fixed on the end of the synchronizing rod 121 away from the synchronizing gear 122. The second drive wheel 123 meshes with the first drive wheel 151. Both the first drive wheel 151 and the second drive wheel 123 are bevel gears.

[0050] Reference Figure 4 and Figure 5 The connecting assembly 13 includes a first synchronous pulley 131, a second synchronous pulley 132, and a synchronous toothed belt 133. The first synchronous pulley 131 is coaxially fixed to one end of the synchronous rod 121 located in the synchronous cavity, and the first synchronous pulley 131 is arranged opposite to the synchronous gear 122. A first connecting cavity 16 communicating with the synchronous cavity is provided in the heat insulation cover 1. The second synchronous pulley 132 is rotatably connected in the first connecting cavity 16. The synchronous toothed belt 133 is wound around the first synchronous pulley 131 and the second synchronous pulley 132, and both the first synchronous pulley 131 and the second synchronous pulley 132 are meshed with the synchronous toothed belt 133. A gear set 4 is connected to the shaft of the second synchronous pulley 132, and the end of the gear set 4 away from the second synchronous pulley 132 is connected to the shaft of the heat-conducting plate 3.

[0051] The gear set 4 includes a first transmission wheel 41 and a second transmission wheel 42. The first transmission wheel 41 is coaxially connected to the shaft of the second synchronous belt pulley 132, and the second transmission wheel 42 is coaxially fixed to the shaft of the heat-conducting plate 3. The second transmission wheel 42 meshes with the first transmission wheel 41. Both the first transmission wheel 41 and the second transmission wheel 42 are bevel gears.

[0052] After the workers cover the insulation cover 1 onto each counterweight, the rotation time of the motor 15 is controlled according to the number of counterweights. The motor 15 starts and drives the first drive wheel 151 to rotate, which in turn drives the second drive wheel 123 to rotate. The second drive wheel 123 then drives the synchronizing rod 121 to rotate, which in turn drives the synchronizing gear 122 and the first synchronizing pulley 131 to rotate. The synchronizing gear 122 drives each mating gear 112 to rotate, which in turn drives the corresponding screw 111 to rotate. Under the limiting action of the moving groove 11, the screw 111 drives the corresponding moving block 21 to move along the moving groove 11. The moving block 21 drives the corresponding heating wire 22 to move, so as to synchronously adjust the position of each heating wire 22 and adjust the concentration of each heating wire 22, so that the heat of each heating wire 22 is more concentratedly distributed in one area.

[0053] During the rotation of the first synchronous pulley 131, the synchronous toothed belt 133 and the second synchronous pulley 132 are driven to rotate. The second synchronous pulley 132 then drives the first transmission wheel 41 to rotate, and the first transmission wheel 41 then drives the second transmission wheel 42 to rotate. The rotation of the second transmission wheel 42 causes the heat-conducting plate 3 to rotate toward the axis of the synchronous rod 121. At this time, the heat-conducting plate 3 can guide the heat emitted by each heating wire 22, so that the heat is more concentrated in the area where the counterweight exists, thereby improving the heat preservation effect of the heat insulation cover 1 on each counterweight.

[0054] Reference Figure 4 and Figure 5 The heat-conducting plates 3 are set to four and are evenly arranged along the circumference of the synchronization rod 121, and the connecting components 13 are set to four groups and control the corresponding heat-conducting plates 3.

[0055] Reference Figure 6 and Figure 7 The inner wall of the heat insulation cover 1 has several clearance grooves 17, four sets of which are located on the four side walls of the heat insulation cover 1. The inner wall of each clearance groove 17 has a guide groove 171, and an adjusting rod 172 is slidably connected to the guide groove 171. A first heat insulation frame 5 and a second heat insulation frame 6 are rotatably connected to the adjusting rod 172. Both the first heat insulation frame 5 and the second heat insulation frame 6 are equipped with heat insulation plates 51. The heat insulation plates 51 are made of asbestos, which has good heat insulation properties, making it difficult for heat inside the heat insulation cover 1 to be conducted to the outside.

[0056] Reference Figure 6 and Figure 7 The heat insulation cover 1 has several control chambers 18, each control chamber 18 corresponds to a heat conduction plate 3, and the control chamber 18 is equipped with a control component for controlling the movement of the adjustment rod 172.

[0057] Reference Figure 6 , Figure 7 and Figure 8 The control assembly includes a first pulley 71, a second pulley 72, a third pulley 73, a control plate 74, and a pull rope 75. The first pulley 71, second pulley 72, and third pulley 73 are all rotatably connected in the control cavity 18. The first pulley 71 and second pulley 72 are arranged opposite each other, and the third pulley 73 is arranged opposite to the second pulley 72. A through hole 173 is provided on the inner wall of the clearance groove 17 to connect the clearance groove 17 and the control cavity 18. The control plate 74 is slidably connected in the through hole 173. One end of the pull rope 75 extends out of the control cavity 18 and is fixed to the corresponding heat-conducting plate 3. The other end is sequentially wound around the first pulley 71, second pulley 72, and third pulley 73 before being fixed to the control plate 74. The end of the control plate 74 away from the pull rope 75 is fixed to the adjusting rod 172 via a mating rod 741. The pull rope 75 has a constant length, the control components are set in several groups, and the cooperating rods 741 are set in several pieces. The cooperating rods 741 are evenly distributed along the length direction of the control plate 74.

[0058] During the rotation of the heat-conducting plate 3, the heat-conducting plate 3 drives one end of the pull rope 75 to move. The pull rope 75 drives the first pulley 71, the second pulley 72, and the third pulley 73 to rotate. The arrangement of the first pulley 71, the second pulley 72, and the third pulley 73 increases the prestress inside the pull rope 75 and reduces the possibility of breakage when the pull rope 75 moves. The other end of the pull rope 75 then drives the control plate 74 to slide along the through hole 173. The control plate 74 then drives the mating rod 741 to move, and the mating rod 741 then drives the adjusting rod 172 to move along the guide groove 171. During the movement of the adjusting rod 172, the adjusting rod 172 drives the first heat insulation frame 5 and the second heat insulation frame 6 to move. When the first heat insulation frame 5 and the second heat insulation frame 6 come into contact with the inner wall of the relief groove 17, the first heat insulation frame 5 and the second heat insulation frame 6 rotate in opposite directions, so that the first heat insulation frame 5 and the second heat insulation frame 6 are in an inclined state. At this time, the heat insulation plates 51 on the first heat insulation frame 5 and the second heat insulation frame 6 both insulate the heat of the heating wire 22 and the counterweight, reducing the possibility that the temperature inside the heat insulation cover 1 will be conducted to the outside through the first heat insulation frame 5 and the second heat insulation frame 6.

[0059] Reference Figure 9 To further improve the heat preservation capacity of the heat preservation cover 1, several heat recovery plates 8 are rotatably connected to the inner wall of the heat preservation cover 1. Each heat recovery plate 8 corresponds to a heat conduction plate 3, and the heat recovery plate 8 and the heat conduction plate 3 are arranged opposite to each other. The control cavity 18 is provided with an adjustment component 9 for controlling the rotation of the heat recovery plates 8.

[0060] The adjusting assembly 9 includes an adjusting block 91 and a connecting member 92. An adjusting groove 181 is formed in the inner wall of the control cavity 18, and the adjusting block 91 is slidably connected in the adjusting groove 181. A second connecting cavity 19, communicating with the adjusting groove 181, is formed in the heat insulation cover 1. The connecting member 92 is disposed in the second connecting cavity 19, with one end connected to the adjusting block 91 and the other end connected to the heat recovery plate 8. A first rack 911 is fixed on the adjusting block 91, and a second rack 742 is provided on the control plate 74, perpendicular to the first rack 911. An adjusting gear 182 is rotatably connected to the inner wall of the control cavity 18, with both the first rack 911 and the second rack 742 meshing with the adjusting gear 182.

[0061] Reference Figure 9 The connecting member 92 includes a connecting rod 921 and a telescopic rod 922. The regenerating plate 8 extends into the second connecting cavity 19 and is fixed to the connecting rod 921. The end of the connecting rod 921 away from the regenerating plate 8 has a telescopic groove 923 along its length, and the telescopic rod 922 is slidably connected in the telescopic groove 923. The adjusting block 91 has a sliding groove 912 on its side near the telescopic rod 922. A slider 913 is slidably connected in the sliding groove 912, and the side of the slider 913 away from the adjusting block 91 is rotatably connected to the telescopic rod 922. The slider 913 is a dovetail-shaped slider, and the sliding groove 912 is a dovetail-shaped groove. A spring 924 is installed in the telescopic groove 923, with one end fixed to the telescopic rod 922 and the other end fixed to the bottom of the groove 923. In its initial state, the regenerating plate 8 is inclined relative to the ground.

[0062] During the movement of the control plate 74, the control plate 74 drives the second rack 742 to move, the second rack 742 drives the adjusting gear 182 to rotate, and the adjusting gear 182 then drives the first rack 911 to move. The first rack 911 drives the adjusting block 91 to move, and the adjusting block 91 then drives the slider 913 to move. The slider 913 drives the telescopic rod 922 to move away from the connecting rod 921, and the spring 924 is in a stretched state. Under the guidance of the adjusting groove 181, the slider 913 can move along the sliding groove 912, while causing the telescopic rod 922 and the connecting rod 921 to rotate. The connecting rod 921 then drives the heat recovery plate 8 to rotate, so that the heat recovery plate 8 rotates to be opposite to the counterweight. At this time, the heat recovery plate 8 further blocks the heat from the heat insulation plate 51 and the heating wire 22, so that the heat is more stably accumulated at the counterweight, reducing the possibility of heat conduction out of the heat insulation cover 1, thereby further improving the heat insulation capacity of the heat insulation cover 1 for each counterweight.

[0063] When the regenerating plate 8, the first heat insulation frame 5, the second heat insulation frame 6, and the heat-conducting plate 3 need to be reset, the output end of the motor 15 reverses. Under the transmission of the first drive wheel 151, the second drive wheel 123, the control lever, the first synchronous pulley 131, the synchronous belt, the second synchronous pulley 132, and the gear set 4, the heat-conducting plate 3 is reset. After the heat-conducting plate 3 is reset, the pull rope 75 is in a slack state. At this time, it automatically resets under the weight of the adjusting block 91, the first rack 911, the slider 913, the telescopic rod 922, and the connecting rod 921. The first rack 911 then drives the adjusting gear 182 to reverse, and the adjusting gear 182 then drives the control plate 74, the cooperating rod 741, and the adjusting rod 172 to reset. The adjusting rod 172 then drives the first heat insulation frame 5 and the second heat insulation frame 6 to automatically reset. At the same time, the control panel 74 pulls the pull rope 75, so that the pull rope 75 is straightened again, so that the workers can continue to use the heat conduction plate 3, the first heat insulation frame 5, the second heat insulation frame 6 and the heat recovery plate 8.

[0064] The implementation principle of the high-temperature firing and curing device for forklift counterweights in this application embodiment is as follows: When it is necessary to keep the counterweights warm for storage, the heat insulation cover 1 is placed over each counterweight. The motor 15 then controls the synchronizing rod 121 to synchronously adjust the movement of each moving block 21, changing the concentration of each heating wire 22, so that each heating wire 22 can more concentratedly keep the counterweight warm. At the same time, under the action of the connecting component 13, the heat conducting plate 3 rotates and guides the heat emitted by the heating wire 22, so that the heat of the heating wire 22 can be diffused more stably to the counterweight. When the heat conducting plate 3 rotates, the control component is activated and the first heat insulation frame 5 and the second heat insulation frame 6 are in an inclined state, so that the heat insulation plate 51 on the first heat insulation frame 5 and the second heat insulation frame 6 can more stably isolate the heat of the counterweight and the heating wire 22. At the same time, the regulating component 9 controls the heat recovery plate 8, further blocking the heat from the counterweight and heat dissipation block, further reducing the possibility of heat being conducted from the heat insulation cover 1 to the outside, thereby further improving the heat insulation effect of the heat insulation cover 1 on each counterweight.

[0065] Secondly, this application also discloses a method for using a high-temperature firing and curing device for forklift counterweights, comprising the following steps:

[0066] Synchronization component 12 controls each screw 111 to rotate synchronously, thereby controlling the movement of each moving block 21 and heating wire 22;

[0067] Synchronization component 12 controls the start of connection component 13, and connection component 13 controls the rotation of heat conduction plate 3;

[0068] The heat-conducting plate 3 drives the control component to start, and the control component controls the first heat insulation frame 5 and the second heat insulation frame 6 to rotate in opposite directions;

[0069] The control panel 74 controls the adjustment component 9 to start, and the adjustment component 9 controls the rotation of the heat recovery plate 8 so that the heat recovery plate 8 is opposite to the heat conduction plate 3.

[0070] Under the action of the synchronization component 12, the positions of each moving block 21 and the heating wire 22 are adjusted synchronously to regulate the concentration of the heating wire 22. Simultaneously, the heat-conducting plate 3 rotates and guides the heat from the heating wire 22, ensuring that the heat emitted by the heating wire 22 is concentrated and transferred to each counterweight, thus improving the insulation effect of the insulation cover 1 on the counterweight. Furthermore, the heat insulation plates 51 on the first and second heat insulation frames 5 and the heat-conducting plate 3 all block the heat from the heating wire 22 and the counterweight, reducing the possibility of heat being conducted out of the insulation cover 1, thereby further improving the insulation effect of the insulation cover 1 on the counterweight.

[0071] 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.
