Description

Technical Field

[0001] This invention belongs to the technical field of walking planar traction devices, specifically a walking planar traction device. Background Technology

[0002] Traditional traction devices have the following shortcomings: First, they adopt a fixed installation method, but when faced with complex application scenarios where the work points are scattered and the traction points are constantly moving, the traction device needs to be disassembled and installed frequently. This is not only inefficient and consumes a lot of labor and time costs, but also poses safety hazards due to frequent disassembly and assembly operations.

[0003] Existing traction devices have fixed cable exit height and direction during traction, making it impossible to adjust the cable exit height and direction according to the traction location of the object being traction. This results in a mismatch between the traction device and the object being tractioned. Therefore, there is an urgent need to design a walking planar traction device to solve the above problems.

[0004] Specific implementation details

[0005] The purpose of this invention is to provide a walking planar traction device that solves the problems of existing traction devices that are fixed on the ground and cannot meet the complex application scenarios of dispersed work points and frequently changing traction points, the need to frequently change the traction fixed area when changing the traction object, and the inability to adjust the height and direction of the rope.

[0006] To solve the above-mentioned technical problems, the present invention provides a walking planar traction device, including a slide rail, a support, a winch mechanism, guide columns, a rope arrangement mechanism, pressure rollers, a first reducer, and a motor. The support is tumblingly connected to the slide rail through several wheel mechanisms. Four sets of guide mechanisms are provided on both sides of the support, and the four sets of guide mechanisms are distributed in pairs and located on both sides of the slide rail. The winch mechanism is mounted on the support through two vertical seats. The support is provided with a cable power supply mechanism for supplying power to the winch mechanism. There are two guide columns arranged vertically side by side between the two vertical seats. There are several pressure rollers, with both ends passing through the two vertical seats and located outside the drum of the winch mechanism. The pressure rollers are used to limit the cable on the drum. Both shaft ends of the drum extend out after passing through the two vertical seats, and the ends are connected to the first reducer. The output end of the motor is connected to the first reducer.

[0007] The rope-laying mechanism includes a first adjusting seat, an upper guide wheel assembly, and a lower guide wheel assembly. The first adjusting seat is slidably mounted on two guide posts. The upper guide wheel assembly is adjustablely connected to the upper part of the first adjusting seat via a second adjusting seat. The lower guide wheel assembly is located at the lower part of the first adjusting seat. Both the upper and lower guide wheel assemblies include a rope-laying wheel and a first guide wheel. There are two rope-laying wheels, which are respectively arranged laterally at the lower part of the first adjusting seat or inside the second adjusting seat. There are two first guide wheels, which are respectively arranged vertically at the lower part of the first adjusting seat or at the cable-laying opening of the second adjusting seat.

[0008] Adjusting the up and down position of the second adjustment seat causes the cable on the hoisting mechanism to pass through the upper guide wheel assembly and the lower guide wheel assembly or the lower guide wheel assembly in sequence and extend out.

[0009] Furthermore, each set of guiding mechanisms includes a fixed frame, a guide rod, and a second guide wheel. The fixed frame is disposed on the side wall of the support. The lower part of the guide rod extends through the fixed frame and connects to the second guide wheel. The upper part is locked by a first fastening nut. A bushing, a thrust bearing, and a retaining ring are sleeved on the guide rod. The bushing and the thrust bearing are both located inside the second guide wheel. A first oil passage is provided inside the guide rod. The first oil passage penetrates the bottom and side surfaces of the guide rod. A first oil cup is installed at the bottom opening. The side outlet communicates with the gap between the bushing and the guide rod.

[0010] Furthermore, the traction device also includes a locking mechanism. There are four locking mechanisms, each corresponding to one side of the guide mechanism. The four locking mechanisms are arranged in pairs, and each group of locking mechanisms includes a clamping arm, an adjusting screw, a limiting block, and an adjusting handle. There are two clamping arms, which are respectively arranged on both sides of the support via a rotating shaft and located on both sides of the slide rail. The adjusting screw has bidirectional threads at both ends, and its threaded ends are screwed through the two clamping arms and then extend out. One end is connected to the adjusting handle, and the other end is limited by a retaining ring. There are two limiting blocks, which are respectively obliquely arranged on one side of the corresponding clamping arm. Each limiting block has an arc-shaped groove on its side wall that limits the rotating shaft. Rotating the adjusting handle drives the adjusting screw to rotate, so that the two clamping arms in each group are clamped or moved away from the sides of the slide rail under the action of the bidirectional threads of the adjusting screw.

[0011] Furthermore, the cable power supply mechanism includes a slip ring box, a second reducer, a winding reel, a hysteresis coupling, and a motor. The slip ring box is mounted on the support via a base. The second reducer is connected to the output end of the slip ring box and the input end of the winding reel, respectively. The winding reel is connected to one side of the second reducer. A cable is wound on the winding reel, and the end of the cable is connected to the motor. The motor is connected to the second reducer via the hysteresis coupling, and the motor is connected to the slip ring box.

[0012] Furthermore, there are four wheel mechanisms, and each wheel mechanism includes a pin, two wheels, a limiting plate, and a bearing cover. The pin passes through the side wall of the support, and the two wheels are sleeved on the inner sides of both ends of the pin. A bearing is sleeved on the pin, and the limiting plate is located on the outer side of the bearing and embedded in the support. There are two bearing covers, which are respectively pressed against the upper and lower parts of the limiting plate. The inner sides of the two bearing covers are provided with arc-shaped grooves, and the arc-shaped grooves abut against the outer wall of the pin.

[0013] Furthermore, two safety mechanisms are provided on the side of the support away from the rope-laying mechanism. Each safety mechanism is located on one side of the corresponding guide mechanism and includes a safety rod and a locking arm. The safety rod is vertically mounted on the fixed frame, with its upper end extending out of the fixed frame and locked by a second fastening nut. Its lower end extends out of the fixed frame and is connected to the locking arm. A second oil passage is provided inside the safety rod. The second oil passage is cross-shaped and extends through the top and side surfaces of the safety rod. A second oil cup is installed at the top inlet of the second oil passage, and the side wall outlet communicates with the gap between the fixed frame and the safety rod. Rotating the safety rod causes the locking arm to grip or rotate away from the slide rail.

[0014] Furthermore, one end of the drum is connected to the first reducer, and the other end is connected to the end of the upper guide post via a synchronous pulley assembly. The end of the upper guide post is connected to a rotating handle.

[0015] The beneficial effects of the present invention: The walking planar traction device of the present invention realizes the rapid deployment, flexible transfer and precise traction of the equipment on the working plane by rolling, so that it can meet the complex application scenarios where the working points are scattered and the traction points are constantly changing. At the same time, it also solves the problem of high disassembly frequency of existing traction devices.

[0016] The position of the cable can be changed by adjusting the position of the rope-laying mechanism to adapt to the height and direction required for traction of the object.

[0017] The cable power supply mechanism enables the winch mechanism to be powered in real time even in a mobile working environment, thus solving the problem of inconvenient power supply when the traction device is moving.

[0018] The rope-laying mechanism is designed so that the vertical position of the second adjusting seat can be changed by adjusting the upper part of the second adjusting seat and the first adjusting seat, thereby changing the height of the upper guide wheel assembly. This allows it to meet the usage requirements of traction objects of various heights, improves the practicality of the traction device, and solves the problem of the limited selection of traction object height in existing devices.

[0019] The guide mechanism ensures that the traction device maintains the same direction of movement during traction, preventing deviation or separation from the slide rail, thus improving the consistency of the traction direction.

[0020] The locking mechanism can be set up by rotating the adjusting handle to drive the adjusting screw to rotate, so that the two clamping arms move closer to the slide rail or away from the unlocking under the action of the bidirectional thread of the adjusting screw, so that the traction device can maintain the stability of the equipment when it is not tractioning or stationary.

[0021] The insurance mechanism can double-lock the traction device to prevent accidents caused by the loss of mechanical fixing force due to malfunction of the locking mechanism.

[0022] The connection between the guide post end and the drum via a synchronous pulley assembly allows the guide post and drum to rotate simultaneously by manually adjusting the rotating handle. This ensures that the rope laying mechanism on the guide post is synchronized with the cable on the drum, guaranteeing smooth cable laying and winding. Attached Figure Description

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0035] In one specific embodiment of the present invention, such as Figure 1-9As shown, a walking planar traction device is disclosed, including a slide rail 1, a support 2, a winch mechanism 4, a guide column 5, a rope-laying mechanism 6, a pressure roller 7, a first reducer 8, and a motor 9. A handle is provided on one side of the support 2. The support 2 is rotatably connected to the slide rail 1 via several wheel mechanisms 10. Four sets of guide mechanisms 11 are provided on both sides of the support 2, distributed in pairs and located on both sides of the slide rail 1. The slide rail 1 is I-shaped. The winch mechanism 4 is mounted on the support 2 via two vertical seats 21. The 2 is equipped with a cable power supply mechanism 12 for supplying power to the hoisting mechanism 4. There are two guide columns 5 arranged side by side between two vertical seats 21. The guide columns 5 are lead screws. There are several pressure rollers 7 with both ends passing through the two vertical seats 21 and located outside the drum 41 of the hoisting mechanism 4. The pressure rollers 7 are used to limit the cable on the drum 41. Both shaft ends of the drum 41 pass through the two vertical seats 21 and extend out, and the ends are connected to the first reducer 8. The output end of the motor 9 is connected to the first reducer 8.

[0036] The rope-laying mechanism 6 includes a first adjusting seat 63, an upper guide wheel assembly 61, and a lower guide wheel assembly 62. The first adjusting seat 63 is slidably mounted on two guide posts 5. The upper guide wheel assembly 61 is adjustablely connected to the upper part of the first adjusting seat 63 via a second adjusting seat 64. The lower guide wheel assembly 62 is located at the lower part of the first adjusting seat 63. Both the upper guide wheel assembly 61 and the lower guide wheel assembly 62 include a rope-laying wheel 612 and a first guide wheel 613. There are two rope-laying wheels 612, which are respectively arranged laterally at the lower part of the first adjusting seat 63 or inside the second adjusting seat 64. There are two first guide wheels 613, which are respectively arranged vertically at the lower part of the first adjusting seat 63 or at the cable-laying opening of the second adjusting seat 64.

[0037] Adjust the up and down position of the second adjustment seat 64, and the cable on the hoisting mechanism 4 passes through the upper guide wheel assembly 61 and the lower guide wheel assembly 62 in sequence or the lower guide wheel assembly 62 and extends out.

[0038] Each guide mechanism 11 includes a fixed frame 111, a guide rod 112, and a second guide wheel 113. The fixed frame 111 is set on the side wall of the support 2. The lower part of the guide rod 112 extends through the fixed frame 111 and is connected to the second guide wheel 113. The upper part is locked by the first fastening nut 114. The guide rod 112 is fitted with a bushing 116, a thrust bearing 117, and a retaining ring 118. The bushing 116 and the thrust bearing 117 are both located inside the second guide wheel 113. The guide rod 112 is provided with a first oil passage 1121, which penetrates the bottom and side surfaces of the guide rod 112. A first oil cup 115 is installed at the bottom opening. The side outlet is connected to the gap between the bushing 116 and the guide rod 112.

[0039] The guide mechanism 11 ensures that the traction device maintains the same direction of movement during traction, preventing deviation or separation from the slide rail, thereby improving the consistency of the traction direction of the traction device.

[0040] The traction device also includes locking mechanisms 3. There are four locking mechanisms 3, each corresponding to one side of the guide mechanism 11. The four locking mechanisms 3 are arranged in pairs, and each pair of locking mechanisms 3 includes a clamping arm 31, an adjusting screw 32, a limiting block 33, and an adjusting handle 34. There are two clamping arms 31, which are respectively arranged on both sides of the support 2 via a rotating shaft 35 and located on both sides of the slide rail 1. The vertical cross-section of each clamping arm 31 is L-shaped, and the two ends of the adjusting screw 32 are provided with bidirectional threads. The threaded end of the arm extends out after being screwed through the two clamping arms 31. One end of the arm is connected to the adjusting handle 34, and the other end is limited by the retaining ring 36. There are two limiting blocks 33, which are respectively obliquely set on one side of the corresponding clamping arm 31. Each limiting block 33 has an arc groove on its side wall that limits the rotating shaft 35. Rotate the adjusting handle 34 to drive the adjusting screw 32 to rotate, so that the two clamping arms 31 of each group are clamped or moved away from the sides of the slide rail 1 under the bidirectional thread drive of the adjusting screw 32.

[0041] The locking mechanism 3 can be set up so that the adjusting screw 32 can be rotated by rotating the adjusting handle 34, thereby adjusting the two clamping arms 31 to move closer to or away from the slide rail 1 under the action of the bidirectional thread of the adjusting screw 32, so that the traction device can maintain the stability of the equipment when it is not tractioning or stationary.

[0042] The cable power supply mechanism 12 includes a slip ring box 121, a second reducer 122, a winding reel 123, a hysteresis coupling 124, and a motor 125. The slip ring box 121 is mounted on the support 2 via a base. The second reducer 122 is connected to the output end of the slip ring box 121 and the input end of the winding reel 123. The winding reel 123 is connected to one side of the second reducer 122. A cable 126 is wound on the winding reel 123. A cable groove is laid along one side of the slide rail 1. The cable groove is used for the cable 126 to pass through. The end of the cable 126 is connected to the motor 9. The motor 125 is connected to the second reducer 122 via the hysteresis coupling 124 and is also connected to the slip ring box 121.

[0043] There are four wheel mechanisms 10, and each wheel mechanism 10 includes a pin 101, two wheels 102, a limiting plate 103, and a bearing cover 104. The pin 101 passes through the side wall of the support 2. The two wheels 102 are sleeved on the inner sides of both ends of the pin 101. A bearing is sleeved on the pin 101. The limiting plate 103 is located on the outer side of the bearing and is embedded in the support 2. There are two bearing covers 104, which are respectively pressed on the upper and lower parts of the limiting plate 103. The inner side of the two bearing covers 104 is provided with an arc-shaped groove 1041, which abuts against the outer wall of the pin 101.

[0044] Two safety mechanisms 13 are provided on the side of the support 2 away from the rope-laying mechanism 6. Each safety mechanism 13 is located on the side of the corresponding guide mechanism 11 and includes a safety rod 131 and a locking arm 132. The safety rod 131 is vertically mounted on the fixed frame 111, and its upper end extends out of the fixed frame 111 and is locked by the second fastening nut 133. Its lower end extends out of the fixed frame 111 and is connected to the locking arm 132. The locking head of the locking arm 132 is trapezoidal. A second oil passage 1311 is provided inside the safety rod 131. The second oil passage 1311 is cross-shaped and runs through the top and side surfaces of the safety rod 131. A second oil cup 134 is installed at the top inlet of the second oil passage 1311. The side wall outlet is connected to the gap between the fixed frame 111 and the safety rod 131. Rotating the safety rod 131 causes the locking arm 132 to grip or rotate away from the slide rail 1.

[0045] The safety mechanism 13 is designed to double-lock the traction device to prevent accidents caused by the loss of mechanical fixing force due to a malfunction of the locking mechanism 3.

[0046] One end of the drum 41 is connected to the first reducer 8, and the other end is connected to the end of the upper guide post 5 through the synchronous pulley assembly 14. The end of the upper guide post 5 is connected to a rotating handle 15. The guide post 5 and the drum 41 are connected through the synchronous pulley assembly 14. By manually adjusting the rotating handle 15, the guide post 5 and the drum 41 can be driven to rotate simultaneously to ensure that the rope laying mechanism 6 on the guide post 5 and the cable on the drum 41 are on the synchronous cable laying line, so as to ensure that the drum 41 can smoothly lay and reel in the cable.

[0047] The walking planar traction device of the present invention achieves rapid deployment, flexible transfer and precise traction of the equipment on the working plane by rolling, which can meet the complex application scenarios where the working points are scattered and the traction points are constantly changing. At the same time, it also solves the problem of high disassembly frequency of existing traction devices. The position of the cable discharge position can be changed by adjusting the position of the rope laying mechanism 6 to adapt to the height and direction required for traction of the object. The cable power supply mechanism 12 enables the winch mechanism 4 to be powered in real time in the moving working environment, so as to solve the problem of inconvenient power supply when the traction device is moving.

[0048] The workflow of this invention:

[0049] During traction, push the handle on the device to drive the wheel mechanism 10 to roll on the slide rail 1. Stop rolling when it reaches the side closest to the object to be traction. Adjust the adjusting handle 34 of the locking mechanism 3 so that the two clamping arms 31 of each locking mechanism 3 clamp onto both sides of the slide rail 1. Push the second adjusting seat 64 so that its end slides into the groove of the first adjusting seat 63 to the desired position and is then locked with bolts. Adjust the vertical position of the upper guide wheel assembly 61 to adjust the height of the cable exiting the drum 41 of the hoisting mechanism 4. The cable passes through the lower guide wheel assembly 62 and then through the upper guide wheel assembly 61. Alternatively, only the lower guide wheel assembly 62 can be used, and the cable on the drum 41 extends directly from the drum 41 and exits from the first guide wheel 613 of the lower guide wheel assembly 62. When the cable exits from the drum 41, several pressure rollers 7 limit the cable being discharged or collected to prevent... The cable may deviate during the winding or unwinding process. Simultaneously, the rotation direction of the rotating handle 15 can be adjusted according to the direction of the object being towed, thereby rotating the guide column 5 to drive the first adjusting seat 63 to slide left and right, thus adjusting the cable's outgoing direction. After adjusting the outgoing direction, the other end of the cable is tied to the object being towed. The motor 9 is controlled to rotate forward or backward as needed to drive the drum 41 to rotate, pulling the cable to retract or release, thereby achieving the traction of the object being towed. During traction, the pushing device causes the wheel mechanism 10 to move under the drive of the slide rail 1, driving the support 2 and all components on the support 2 to roll on the slide rail 1, thus pulling heavy objects and reducing manpower and material resources. Simultaneously, during the traction process, several guide mechanisms 11 on the bottom sidewall of the support 2 guide the rolling device on both sides of the slide rail 1, ensuring it remains rolling on the slide rail 1 and does not detach from it.

[0050] When the cable power supply mechanism 12 supplies power to the hoisting mechanism 4, the cable 126 is connected to an external power source, starting the motor 125. The hysteresis coupling 124 transmits the power of the motor 125 to the second reducer 122. The second reducer 122 reduces the power and then transmits it to the slip ring box 121 and the winding reel 123 of the cable power supply mechanism 12. The slip ring box 121 of the cable power supply mechanism 12 continuously provides electrical energy and signals to the motor 9 through its internal rotating components. When the motor 9 rotates forward or backward, the first reducer 8 reduces the rotational power transmitted by the motor 9 and then transmits it to the hoisting mechanism 4, thereby driving the drum 41 to rotate forward or backward. The rotation of the winding reel 123 can reel in and out the cable 126. The length of the reel in and out can be adjusted according to the moving position to meet the usage requirements of the traction device during the movement process, realizing the traction of the traction object in a long-distance energized environment.

[0051] When the traction device needs to be stopped, turn the adjusting handle 34 to drive the adjusting screw 32 to rotate. Under the action of the bidirectional thread of the adjusting screw 32, the two clamping arms 31 move closer to both sides of the slide rail 1 to hold the slide rail 1. The lower ends of the two clamping arms 31 hook the upper bent part of the slide rail 1 to restrict the movement of the wheel mechanism 10 on the slide rail 1. At the same time, turn the locking arms 132 of the two safety mechanisms 13 so that the trapezoidal locking heads at their lower ends lock the upper bent part of the slide rail 1 to double lock the traction device and double prevent the wheel mechanism 10 from rolling, so as to prevent the traction device from not pulling or from operating stably in the working environment.

[0052] The above description is merely a preferred embodiment of the present invention and should not be construed as limiting the scope of the invention. Therefore, any equivalent variations made in accordance with the claims of the present invention are still within the scope of the present invention.
