Description

Technical Field

[0001] This utility model belongs to the field of tunnel kiln technology, and specifically relates to a bidirectional high-efficiency trailer structure and drying production line. Background Technology

[0002] After refractory and building materials are placed in the kiln car, the kiln car needs to undergo pre-drying, horizontal movement and other processes on multiple guide rails. The kiln car returning from the loading car to the storage line is sent to the pre-drying guide rail production line, and the kiln car returning from the unloading machine to the loader is sent back to the loader production line. The kiln car switches back and forth between multiple production lines.

[0003] The existing technology involves setting up a push hook mechanism at the front or rear of the transfer car to enable the kiln car to get on and off. However, the transfer car can only operate in one direction, and multiple mechanisms are required to achieve back-and-forth operation, resulting in high investment costs.

[0004] Another existing technology is a double kiln car trailer, which can accommodate two kiln cars. The trailer is equipped with bidirectional push hooks, which are dedicated to one vehicle and allow loading and unloading in one direction. However, the mechanical cost is doubled. Utility Model Content

[0005] The purpose of this utility model is to provide a bidirectional high-efficiency trailer structure and drying production line to solve one or more technical problems existing in the prior art.

[0006] The technical solution adopted to solve the above-mentioned technical problems is as follows: This utility model discloses a bidirectional high-efficiency trailer structure for transporting kiln car assemblies. The bidirectional high-efficiency trailer structure includes a frame assembly and a hook assembly. The hook assembly includes: A two-way slide block is slidably connected to the frame assembly along a first direction, and a barb assembly is rotatably connected to the two-way slide block; A first motor is connected to the frame assembly, and the output end of the first motor is connected to the bidirectional slide transmission. A hook slide block, wherein the hook slide block and the bidirectional slide block are slidably connected along a first direction; A control hydraulic cylinder is connected to the bidirectional slide block, and the output end of the control hydraulic cylinder is connected to the hook slide block, so that the hook assembly rotates to the hook position connected to the kiln car assembly, or the hook assembly rotates to the unhooking position for the kiln car assembly to enter and exit.

[0007] The present invention has at least the following beneficial effects: The control hydraulic cylinder is activated, causing the hook slide and the bidirectional slide to slide relative to each other along a first direction, rotating the hook assembly to the unhooking position. Then, the first motor is activated, causing the bidirectional slide and the frame assembly to slide relative to each other along the first direction, driving the hook assembly to move below the kiln car assembly. The control hydraulic cylinder is activated again, causing the hook assembly to rotate to the hooking position. Then, the first motor is activated again; at this time, the bidirectional slide and the frame assembly, moving in the opposite direction, can drive the hook assembly to move, hooking the kiln car assembly and driving the kiln car assembly to move along the first direction. After movement, the hook assembly can be disengaged from the hooking state by reactivating the control hydraulic cylinder and the first motor.

[0008] By using the reverse of the above steps, the kiln car assembly can also move in the opposite first direction. Therefore, only a single bidirectional high-efficiency trailer structure is needed to achieve bidirectional movement of the kiln car assembly, breaking away from the existing multi-lane, multi-set equipment investment scheme, reducing the investment cost of mechanical equipment, improving plant utilization, and reducing plant operating costs.

[0009] As a further improvement to the above technical solution, the two ends of the hook assembly are a movable end and a fixed end, respectively. The bidirectional high-efficiency trailer structure is configured such that the control hydraulic cylinder drives the hook slide to abut the movable end, causing the hook assembly to rotate to the unhooking position.

[0010] As a further improvement to the above technical solution, the hook assembly includes two hooks arranged opposite each other along a first direction. The hooks are rotatably connected to the bidirectional slide block. The ends of the two hooks that are close to each other are the two movable ends. The bidirectional high-efficiency trailer structure is configured such that the control hydraulic cylinder controls the hooks that are away from the forward direction of the kiln car assembly to rotate to the hook position or the unhooking position.

[0011] As a further improvement to the above technical solution, the pressure hook slide is provided with a connecting hole for the hook to rotate through.

[0012] As a further improvement to the above technical solution, the barb assembly is provided in two parts and is rotatably connected to both ends of the bidirectional slide along the first direction.

[0013] As a further improvement to the above technical solution, the bidirectional high-efficiency trailer structure also includes a translation assembly that drives the frame assembly to move along a second direction. The translation assembly includes a second motor, a drive wheel axle, a power slider, and wheels. The second motor is connected to the frame assembly, and the drive wheel axle is rotatably connected to the frame assembly. A power slider is provided between the output end of the second motor and the drive wheel axle. Wheels are connected to both ends of the drive wheel axle along a first direction. The first direction and the second direction are mutually perpendicular horizontal directions.

[0014] As a further improvement to the above technical solution, the translation assembly also includes multiple sensor brackets that correspond one-to-one with multiple return line guide rails and are connected to the ground. The frame assembly is connected to a sensor that is electrically connected to the second motor. The sensor is configured to turn off the second motor when it is signal-connected to the sensor bracket.

[0015] As a further improvement to the above technical solution, the bidirectional high-efficiency trailer structure also includes a locking assembly, which includes a positioning hydraulic cylinder, a positioning block, and a positioning bracket. The positioning hydraulic cylinder is connected to the frame assembly, and the output end of the positioning hydraulic cylinder is connected to the positioning block. The positioning bracket includes a positioning end connected to the ground. The locking assembly is configured such that when the positioning block is in contact with the positioning end, the frame assembly aligns with a translational guide rail extending in a second direction.

[0016] As a further improvement to the above technical solution, the bidirectional high-efficiency trailer structure also includes a brake spring, one end of which is connected to the frame assembly, and the other end of which is used to abut against the kiln car assembly located above the frame assembly.

[0017] This utility model also discloses a drying production line, including a return line guide rail, a translation car guide rail, and a bidirectional high-efficiency trailer structure as described in any one of the above.

[0018] The present invention has at least the following beneficial effects: the bidirectional high-efficiency trailer structure enables the kiln car assembly to enter and exit in both directions, thereby reducing the setup cost of the drying production line. Attached Figure Description

[0021] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0022] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] In the description of this utility model, the use of terms such as "several" means one or more, with "multiple" meaning two or more. Terms like "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. The use of terms like "first," "second," and "third" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, the quantity of indicated technical features, or the sequential relationship between indicated technical features.

[0024] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0025] In related technologies, the translation car can achieve unidirectional pushing and hooking, hooking out from the tail of the kiln, moving horizontally to the return line, and then pushing the kiln car out to the return line. The return line can only run in one direction and cannot run back and forth.

[0026] Reference Figures 1 to 9 The following are several embodiments of a bidirectional high-efficiency trailer structure and drying production line of this utility model.

[0027] like Figure 9 As shown, the drying production line 800 of this embodiment includes a return line guide rail 870, a translation trolley guide rail 880, and a bidirectional high-efficiency trailer structure 100. Specifically, the return line guide rail 870 extends along a first direction, and multiple return line guide rails 870 are provided and spaced apart along a second direction. The translation trolley guide rail 880 extends along the second direction, and the first and second directions are mutually perpendicular horizontal directions. Multiple return line guide rails 870 are perpendicularly inserted into the translation trolley guide rail 880.

[0028] Understandably, the bidirectional high-efficiency trailer structure 100 slides along the second direction within the translational car guide rail 880. When the bidirectional high-efficiency trailer structure 100 is aligned with the return line guide rail 870, it can receive the kiln car assembly 910 from the return line guide rail 870 and transport the kiln car assembly 910 to the opposite return line guide rail 870 along the first direction; the bidirectional high-efficiency trailer structure 100 can also transport the kiln car assembly 910 to another return line guide rail 870 along the second direction after receiving it, facilitating the rapid switching of the kiln car assembly 910 to the return line guide rail 870.

[0029] With this configuration, the bidirectional high-efficiency trailer structure 100 can switch back and forth along the second direction multiple return line guide rails 870, breaking the existing investment scheme of multiple tracks and multiple equipment in the drying production line 800, reducing mechanical investment costs, creating a process route for multi-guide rail storage kiln car assembly 910, improving plant utilization, and reducing plant operating costs.

[0030] In this embodiment, the first direction is the left-right direction, and the second direction is the front-back direction.

[0031] like Figures 1 to 9 As shown, the bidirectional high-efficiency trailer structure 100 of this utility model embodiment is used to transport the kiln car assembly 910. The bidirectional high-efficiency trailer structure 100 includes a connected frame assembly 200 and a hook assembly 300. The frame assembly 200 is used to carry and transport the kiln car assembly 910 in a second direction. The hook assembly 300 is used to hook the kiln car assembly 910 from the return line guide rail 870 onto the frame assembly 200, and then push the kiln car assembly 910 from the frame assembly 200 to the other side of the same return line guide rail 870 or another return line guide rail 870.

[0032] In this embodiment, the hook assembly 300 includes a barb assembly 320, a bidirectional slide 310, a first motor 330, a hook pressing slide 340, and a control hydraulic cylinder 350.

[0033] Understandably, the two-way slide block 310 is slidably connected to the frame assembly 200. Specifically, the frame assembly 200 includes a guide rail 210 for supporting the hook assembly 300, such as... Figure 2 As shown. The two ends of the bidirectional slide 310 are rotatably connected to guide wheels, the shaft of the guide wheels extends along the second direction, and the guide groove frame 210 is provided with a sliding groove. The guide wheels are rolled to the sliding groove to realize the sliding connection between the bidirectional slide 310 and the guide groove frame 210 along the first direction.

[0034] Understandably, the hook assembly 320 is rotatably connected to the bidirectional slide 310, and their rotation axes extend along the second direction, allowing the hook assembly 320 to rotate and switch between the hook position and the unhooked position. Specifically, when the hook assembly 320 rotates to the hook position, it connects to the kiln car assembly 910, at which point the hook assembly 300 can move the kiln car assembly 910. When the hook assembly 320 rotates to the unhooked position, it does not interfere with the kiln car assembly 910, and the kiln car assembly 910 and the hook assembly 300 can move relative to each other, facilitating the entry and exit of the kiln car assembly 910 into and out of the frame assembly 200.

[0035] Understandably, the first motor 330 is connected to the frame assembly 200, and the output end of the first motor 330 is connected to the bidirectional slide 310 for transmission. Specifically, the first motor 330 is fixedly connected to the guide rail frame 210 by bolts, such as... Figure 2 As shown. The output end of the first motor 330 is connected to a drive shaft, which extends along the second direction and is rotatably connected to the guide frame 210 at both ends via bearings. A drive sprocket 331 is sleeved and fixed on the outside of the drive shaft. Chains are rotatably mounted on both ends of the guide frame 210 along the first direction, and the chains are engaged with the drive sprockets 331. The bidirectional slide 310 is fixedly connected to the chain via a chain connecting seat 332 and bolts.

[0036] Thus, when the first motor 330 starts, the output end of the first motor 330 drives the drive shaft to rotate, thereby driving the chain to rotate, so that the bidirectional slide 310 and the guide rail frame 210 move relative to each other in the first direction.

[0037] It is understandable that the press hook slide 340 and the bidirectional slide 310 are slidably connected along the first direction, such as... Figure 2 As shown, the sliding structure between the two is also achieved by the same sliding structure between the bidirectional slide 310 and the guide slot frame 210, that is, the two ends of the press hook slide 340 are rotatably connected with guide wheels along the second direction, and the two ends of the bidirectional slide 310 are provided with sliding slots.

[0038] It is understandable that the control hydraulic cylinder 350 and the bidirectional slide 310 are fixedly connected by bolts, and the output end of the control hydraulic cylinder 350 moves linearly in the first direction and is connected to the pressure hook slide 340, such as... Figure 8 As shown. Thus, when the control hydraulic cylinder 350 is activated, the pressure hook slide 340 and the bidirectional slide 310 move relative to each other in the first direction.

[0039] With this configuration, when the kiln car assembly 910 moves along the return line guide rail 870 to the side of the translation car guide rail 880, the control hydraulic cylinder 350 is activated. The hook pressing slide 340 slides relative to the bidirectional slide 310 in the first direction. The hook pressing slide 340 drives the hook assembly 320 to rotate, so that the hook assembly 320 is in the unhooked position. The first motor 330 is activated, and the bidirectional slide 310 slides relative to the frame assembly 200 in the first direction. The bidirectional slide 310 drives the hook assembly 320 to move. Until the hook assembly 320 passes the kiln car assembly 910; the control hydraulic cylinder 350 is activated again, causing the hook assembly 320 to rotate to the hook position, and the first motor 330 is activated again, causing the bidirectional slide block 310 to slide in the opposite direction. At this time, the hook assembly 320 in the hook position is connected to the kiln car assembly 910, and the first motor 330 drives the kiln car assembly 910 to move closer to the frame assembly 200, so that the kiln car assembly 910 is above the frame assembly 200. The frame assembly 200 can move along the translation guide rail 880, thereby driving the kiln car assembly 910 to switch to other return line guide rails 870.

[0040] When the kiln car assembly 910 needs to move from the frame assembly 200 to the return line guide rail 870, the control hydraulic cylinder 350 is activated to put the hook assembly 320 in the unhooked position. The first motor 330 is activated, and the hook slide 340 moves in the opposite direction to the moving direction of the kiln car assembly 910 until the hook assembly 320 passes the kiln car assembly 910. The control hydraulic cylinder 350 is activated again to put the hook assembly 320 in the hook position. The first motor 330 is activated again to make the bidirectional slide 310 slide in the opposite direction. The hook assembly 320 in the hook position connects with the kiln car assembly 910 and drives the kiln car assembly 910 to move from the frame assembly 200 to the return line guide rail 870.

[0041] Understandably, during the towing process, the hook assembly 320 can first connect with the end of the kiln car assembly 910 closest to the forward direction. After towing a certain distance, the control hydraulic cylinder 350 and the first motor 330 are activated in sequence to connect the hook assembly 320 with the end of the kiln car assembly 910 furthest from the forward direction, thereby extending the towing distance of the bidirectional high-efficiency towing structure 100. This ensures that the bidirectional high-efficiency towing structure 100 can stably transport the kiln car assembly 910 to the frame assembly 200 or the return line guide rail 870, realizing the long-distance pushing function.

[0042] Furthermore, such as Figure 3 As shown, the movable sprocket 220 is rotatably connected to the movable sprocket fork 230, the movable sprocket fork 230 is slidably connected to the guide slot seat 240, the guide slot seat 240 is connected and fixed to the guide slot frame 210, the chain is wound around the movable sprocket 220, one end of the spring 250 is connected to the movable sprocket fork 230, and the other end of the spring 250 is connected to the guide slot frame 210, automatically adjusting the elastic tension of the chain.

[0043] Furthermore, the hook slide 340 has two hook sensors, which are electrically connected to the first motor 330. Specifically, the two hook sensors are spaced apart along the first direction and connected to the bidirectional slide 310. The hook sensors are used to sense the hook slide 340. When one of the hook sensors senses the hook slide 340, it sends a signal to the first motor 330. After receiving the signal, the first motor 330 automatically shuts down. At this time, the hook assembly 320 is in the hook position. Similarly, when the other hook sensor senses the hook slide 340, the hook assembly 320 is in the unhooking position.

[0044] In this way, the hook sensor can accurately control the shutdown of the first motor 330, so that the hook assembly 320 can be accurately positioned in the hook car position or the unhooking position.

[0045] It is understood that the kiln car assembly 910 is a kiln car structure of the prior art. This utility model does not improve the structure of the kiln car assembly 910. Therefore, those skilled in the art should understand the specific structure and working principle of the kiln car assembly 910, which will not be explained in detail here.

[0046] It is understood that the two ends of the hook assembly 320 are a movable end and a fixed end, respectively. Specifically, the hydraulic cylinder 350 drives the hook slide 340 to move closer to or away from the movable end. When the distance between the hook slide 340 and the movable end is set, the hook assembly 320 is in the hook position, the first motor 330 starts, and the movable end, which is closer to the kiln car assembly 910 in the forward direction, connects with the kiln car assembly 910. At this time, the fixed end abuts against the bidirectional slide 310, thereby stably driving the kiln car assembly 910 to move. When the hook slide 340 approaches and abuts against the movable end, the hook assembly 320 is driven by the hook slide 340 to rotate to the unhooking position. At this time, the movable end rotates to the bottom of the kiln car assembly 910, the first motor 330 starts, and it does not affect the movement of the kiln car assembly 910 in the first direction.

[0047] In some embodiments, the barb assembly 320 is an independent integral structure. Specifically, the two ends of the barb assembly 320 are symmetrically arranged along the first direction. Therefore, by controlling the hydraulic cylinder 350 to drive the hook slide 340, the barb assembly 320 is respectively connected to the two end faces of the movable end along the first direction to realize bidirectional trolley pushing.

[0048] Understandably, the hook slide 340 can abut against the end face of the movable end that is away from the forward direction of the kiln car assembly 910, so that the hook assembly 320 is stably in the hook position, realizing the stable trailer of the bidirectional high-efficiency trailer structure 100.

[0049] It is understandable that the shapes of the two end faces of the movable end of the hook assembly 320 along the first direction can correspond to the kiln car assembly 910. For example, the end face of the movable end that connects with the kiln car assembly 910 can be the end face perpendicular to the first direction.

[0050] In this embodiment, the barb assembly 320 includes two hooks 321 disposed opposite to each other along a first direction, such as... Figure 8 As shown. Specifically, the pin-mounted hook seat is fixedly connected to the bidirectional slide 310, and the hook 321 is rotatably connected to the pin-mounted hook seat, realizing the rotatable connection between the hook 321 and the bidirectional slide 310. The two opposite ends of each hook 321 are the movable end and the fixed end, respectively, and the ends of the two hooks 321 that are close to each other are the movable ends. When the bidirectional high-efficiency trailer structure 100 needs to trailer the kiln car assembly 910, the pressing hook slide 340 only acts on the hook 321 that is away from the forward direction of the kiln car assembly 910. When the hook 321 away from the forward direction of the kiln car is in the hooking position, the movable end is used to connect with the kiln car assembly 910, and the fixed end is used to abut against the pin-mounted hook seat. At this time, the hook 321 away from the forward direction of the kiln car is in a stable hooking position, and the bidirectional high-efficiency trailer structure 100 can trailer stably.

[0051] Understandably, the hook 321, which is close to the forward direction of the kiln car assembly 910, does not interfere with the forward movement of the kiln car assembly 910. During the towing process, the hook 321 can naturally connect with the kiln car assembly 910 and be rotated to the unhooked position.

[0052] It is understandable that the movable end of the hook 321, which is far from the forward direction of the kiln car assembly 910, is closer to the forward direction of the kiln car assembly 910 than the fixed end.

[0053] In this embodiment, the hook 321 in the hook position is a diagonal bar structure. Specifically, the movable end has a vertical surface that smoothly connects with the kiln car assembly 910, and the fixed end has a horizontal surface that smoothly abuts against the bidirectional slide 310.

[0054] Understandably, the hook slide 340 is provided with a connecting hole, and the hook 321 rotates through the connecting hole. Specifically, when the hook assembly 320 is in the hook car position, the movable end of the hook 321, which is away from the forward direction of the kiln car assembly 910, rotates upward and out of the connecting hole. The control hydraulic cylinder 350 is activated, and the movable end of the hook 321, which is away from the forward direction of the kiln car assembly 910, is driven downward by the hook slide 340, causing the movable end to disengage from the connecting hole and be spaced apart from the connecting hole along the first direction, ensuring that the hook assembly 320 is in the retracted position.

[0055] Furthermore, two hook assemblies 320 are provided and rotatably connected to both ends of the bidirectional slide block 310 along the first direction. With this configuration, when the kiln car assembly 910 is towed into the frame assembly 200, the hook assembly 320 furthest from the kiln car's forward direction can be moved by the first motor 330 to a position further away from the frame assembly 200, acting on the pulley at the end of the kiln car assembly 910 closest to the forward direction, ensuring the kiln car assembly 910 can be stably transported onto the frame assembly 200. When the kiln car assembly 910 is towed out of the frame assembly 200, the hook assembly 320 closest to the kiln car's forward direction can act on the pulley at the end of the kiln car assembly 910 furthest from the forward direction, enabling the bidirectional high-efficiency towing structure 100 to achieve long-distance towing of the kiln car assembly 910.

[0056] Correspondingly, the hook slide 340 is provided with two connecting holes spaced apart along the first direction. By controlling the hydraulic cylinder 350 to drive the hook slide 340, the two hook assemblies 320 can be switched between hook car position and hook retraction position at the same time, that is, the two hook assemblies 320 are close to the hook 321 in the kiln car forward direction. Understandably, the bidirectional high-efficiency trailer structure 100 also includes a translation assembly 400, which drives the frame to move in the second direction, enabling the kiln car assembly 910 to switch between different return line guide rails 870, such as... Figure 4 As shown, the translation assembly 400 includes a second motor 410, a drive wheel axle 420, and wheels 440. Specifically, the second motor 410 is connected to the frame assembly 200, and the drive wheel axle 420 is rotatably connected to the frame assembly 200 via bearings. Both the output end of the second motor 410 and the drive wheel axle 420 extend along a first direction and are driven by a chain drive between a sprocket and a chain. Wheels 440 are connected to both ends of the drive wheel axle 420 along the first direction.

[0057] With this configuration, when the second motor 410 starts, the drive wheel axle 420 drives the wheel 440 to rotate around the axis in the first direction, so that the frame assembly 200 can drive the kiln car assembly 910 to move in the second direction.

[0058] Furthermore, the translation assembly 400 also includes a powered slider 430, such as... Figure 4 As shown, the power slider 430 is located between the output end of the second motor 410 and the drive wheel axle 420. Specifically, the power slider 430 is configured to cooperate with the drive wheel axle 420 and can slide relative to the drive wheel axle 420 to control the power supply between the sprocket and the drive wheel axle 420, thereby realizing the on / off control of the power output of the second motor 410.

[0059] It is understandable that a positioning spacer 460 is fitted at the position where the drive wheel axle 420 connects to the sprocket, such as... Figure 4 As shown.

[0060] Understandably, the translation assembly 400 also includes sensor brackets 510, with multiple sensor brackets 510 corresponding one-to-one with multiple return line guide rails 870. Specifically, the sensor brackets 510 are connected to the ground, and the frame assembly 200 is connected to sensors 520, such as... Figure 1 As shown. Sensor 520 is signal-connected to sensor bracket 510, and sensor 520 is also electrically connected to second motor 410. When the chassis assembly 200 needs to move along the second direction to the desired return line guide rail 870, if sensor 520 senses the sensor bracket 510 at the corresponding position, sensor 520 sends a signal to second motor 410, causing second motor 410 to turn off, so that chassis assembly 200 stops precisely on the corresponding return line guide rail 870.

[0061] Understandably, the frame assembly 200 is connected to the mounting aluminum square via a clamp, the mounting aluminum square is connected to the sensor mounting plate, and the sensor 520 is mounted on the sensor mounting plate.

[0062] Understandably, the bidirectional high-efficiency trailer structure 100 also includes a locking assembly 600, which includes a positioning hydraulic cylinder 610, a positioning block 620, and a positioning bracket 630, such as... Figure 6 and Figure 7 As shown. Specifically, the positioning hydraulic cylinder 610 is connected and fixed to the frame assembly 200, and the output end of the positioning hydraulic cylinder 610 is connected to the positioning block 620, enabling the positioning block 620 to move linearly along a first direction. The positioning bracket 630 includes a positioning end that is welded and fixed to the ground.

[0063] With this configuration, when the positioning hydraulic cylinder 610 is started, the output end of the positioning hydraulic cylinder 610 drives the positioning block 620 to move along the first direction, so that the positioning block 620 is connected and positioned with the positioning bracket 630, ensuring that the wheels 440 of the frame assembly 200 are aligned with the translation guide rail 880, and preventing the frame from shifting along the first direction during the towing process of the hook assembly 300.

[0064] Furthermore, the output end of the positioning hydraulic cylinder 610 is connected to one end of the positioning rod via a fisheye connector. The positioning rod is rotatably connected to the frame assembly 200 via a bearing. The other end of the positioning block 620 is fixedly connected to the positioning block 620, so that the positioning block 620 moves precisely in a straight line along the first direction.

[0065] In this embodiment, the vehicle locking assembly 600 has two locking assemblies, which are respectively located at both ends of the frame assembly 200 along the first direction, such as... Figure 6 and Figure 7 As shown.

[0066] Understandably, the frame assembly 200 is connected to a positioning sensor 640 for detecting that the positioning block 620 has moved into place, such as... Figure 7 As shown. The positioning sensor 640 is electrically connected to the positioning hydraulic cylinder 610. When the positioning sensor 640 receives information that the positioning block 620 has moved into place, it sends an electrical signal to the positioning hydraulic cylinder 610, causing the positioning hydraulic cylinder 610 to close, so that the wheels 440 of the frame assembly 200 are precisely aligned with the translation vehicle guide rail 880.

[0067] It is understandable that the positioning hydraulic cylinder 610 is connected to the pump station 650, such as Figure 4 As shown, the pump station 650 is connected to the frame assembly 200 by bolts. The pump station 650 includes a first output end and a second output end. The first output end is split into two positioning hydraulic cylinders 610 via a tee. The second output end is connected to the control hydraulic cylinder 350, enabling one pump station 650 to drive one control hydraulic cylinder 350 and two positioning hydraulic cylinders 610.

[0068] Understandably, the control hydraulic cylinder 350 and the positioning hydraulic cylinder 610 can also be replaced by pneumatic cylinders or electric cylinders, etc.

[0069] It is understandable that the bidirectional slide 310 is bolted to the cable chain bracket 311, such as... Figure 2 As shown, one end of the cable chain 312 is connected to the cable chain bracket 311, and the other end of the cable chain 312 is connected to the cable chain 312 slot on the frame. The oil pipe at the second output end is connected to the control hydraulic cylinder 350 through the cable chain 312.

[0070] Understandably, the bidirectional high-efficiency trailer structure 100 also includes a brake spring 260, such as... Figure 1 and Figure 4 As shown, the brake spring 260 is designed to extend and retract along the second direction, with one end of the brake spring 260 connected and fixed to one end of the frame assembly 200 along the second direction. When the hook assembly 300 drags the kiln car assembly 910 above the frame assembly 200, the other end of the brake spring 260 abuts against the kiln car assembly 910, pressing the kiln car assembly 910 firmly to prevent the kiln car assembly 910 from slipping along the second direction when the translation assembly 400 moves the kiln car assembly 910 along the second direction.

[0071] Furthermore, two brake springs 260 may be provided, so that the frame assembly 200 clamps the kiln car assembly 910 from both ends in the second direction.

[0072] Understandably, the wheel adjusting block 450 is connected to the frame assembly 200 by bolts, such as Figure 5 As shown, this is to adjust the height of wheel 440. The power control cabinet 270 is connected to the frame assembly 200 by bolts, as... Figure 1 As shown.

[0073] Understandably, the first motor 330 and the second motor 410 are driven by existing variable frequency motors to achieve smooth start-up, reduce energy consumption, and reduce the impact on the power grid during startup.

[0074] Understandably, the bidirectional high-efficiency trailer structure 100 also includes a power take-up assembly 700, which includes a wire groove bracket 710, a multi-core wire groove 720, and a power take-up claw 730, such as... Figure 1 As shown. Specifically, multiple marking groove brackets 710 are provided and spaced apart along the second direction. The marking groove brackets 710 are fixed to the ground by bolts. The upper end of the marking groove brackets 710 is fixedly connected to the multi-core wire groove 720 by bolts. One end of the power take-up claw 730 is connected to the frame assembly 200, that is, one end of the power take-up claw 730 is connected to the power control cabinet 270; the other end of the power take-up claw 730 is connected to the multi-core wire groove 720, so that the frame assembly 200 can take power from the multi-core wire groove 720 during the movement of the frame assembly 200 along the second direction.

[0075] In some embodiments, the return line guide rail 870 is provided with translation guide rails 880 at the middle and both ends, such as... Figure 9 As shown, the bidirectional high-efficiency trailer structure 100 slides on the translation rail 880 located in the middle. The two translation rails 880 at both ends of the return line rail 870 are equipped with existing one-way trailers 920, so that the kiln car assembly 910 near the end of the return line rail 870 can switch the return line rail 870 through the translation rails 880 on both sides and the one-way trailer 920.

[0076] Understandably, one of the return line guide rails 870 has a loader 930 and an unloader 940 installed at each end, such as... Figure 9 As shown, the kiln car assembly 910 can load products into the loader 930 and unload products onto the unloader 940.

[0077] The operating route of the bidirectional high-efficiency trailer structure 100 is as follows: the kiln car assembly 910 at station 1 (810) is moved horizontally by the bidirectional high-efficiency trailer structure 100 to station 2 (820), and then transported by a stepper to station 3 (830) equipped with a loader 930. The loader 930 places the products to be dried onto the kiln car assembly 910. The fully loaded kiln car assembly 910 is then moved horizontally by the unidirectional trailer 920 to station 4 (840). Station 4 (840)... 40 is conveyed to station 5 (850) by a stepper motor. The hook assembly 300 pulls the fully loaded kiln car assembly 910 onto the frame assembly 200. The locking assembly 600 is released, and the translation assembly 400 is activated to move the car onto any of the return line guide rails 870 used for pre-drying. The positioning hydraulic cylinder 610 is activated to align the frame assembly 200 with the return line guide rail 870. The hook assembly 300 then sends the fully loaded kiln car out for product pre-drying. Figure 9 As shown.

[0078] After pre-drying, the fully loaded kiln car assembly 910 is transported to station 6 860 equipped with unloading machine 940 using a two-way high-efficiency trailer structure 100 or a one-way trailer 920. After unloading, it is transported to station 1 810 via a stepper to repeat the steps.

[0079] Understandably, at the same time, the empty kiln car assembly 910 is pulled onto the frame assembly 200 from another return line guide rail 870 using the same method, and the empty car is sent to the return line guide rail 870 equipped with a loader 930, thus realizing a cyclical double-in-out process route.

[0080] The operation process of the bidirectional high-efficiency trailer structure 100: the kiln car assembly 910 is in place, the locking assembly 600 is working, the positioning block 620 extends to contact the positioning bracket 630, so that the frame assembly 200 is aligned with the return line guide rail 870, the first motor 330 drives the drive sprocket 331 to rotate, which drives the chain connecting seat 332 and the bidirectional slide 310 to move, and the control hydraulic cylinder 350 is pushed out. The two hooks 321 of the two hook assemblies 320 in the same direction rotate to one side to the hook position, and the kiln car assembly 910 is sent from the return line guide rail 870 to the frame assembly 200. When the locking assembly 600 is activated, the positioning block 620 retracts, and the second motor 410 starts, causing the frame assembly 200 to move along the second direction to the required return line guide rail 870. The sensor 520 of the frame assembly 200 is connected to the ground sensor bracket 510, enabling the frame assembly 200 to achieve slow start, fast lateral movement, and deceleration upon approaching the lane. The above actions are repeated to lock the car. The first motor 330 drives the drive sprocket 331 to rotate, which drives the chain connecting seat 332 and the bidirectional slide 310 to move linearly, sending the kiln car assembly 910 out to the return line guide rail 870, thus completing the action.

[0081] When the hook is reversed, the hydraulic cylinder 350 needs to be controlled to retract, and the two hook parts 321 of the two hook assemblies 320 in the other direction need to rotate to the hook position.

[0082] Understandably, during the translation of the frame assembly 200 in the second direction, the control hydraulic cylinder 350 can be pushed to the center of the stroke, so that both sets of hook assemblies 320 are in a free state, preventing the kiln car assembly 910 from slipping along the first direction.

[0083] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
