Description

Technical Field

[0001] The present invention relates to the technical field of mechanical traction and transportation, and particularly to a transfer device for the production of large construction machinery. Background Technique

[0002] During the production process of large mechanical equipment, due to the large volume and weight of the equipment itself, the related equipment for processing it is also large in size. During the entire processing process, it is necessary to continuously transfer the mechanical equipment raw materials and cooperate with various processing equipment on the production line to achieve the processing and production operations of the components of large mechanical equipment.

[0003] According to a disclosed transportation auxiliary device for construction machinery (Publication No.: CN208700440U), in the above application, by starting the hydraulic rod to jack up the support rod upwards, one end of the support rod rotates around the upper end of the fixed seat, and the other end rises to lift the heavy object. The extension height of the hydraulic cylinder is adjusted according to the required height, and the support rod can be extended to a higher position. By installing the lifting device on the turntable and controlling the rotation with a motor, transportation and unloading can be started in all directions.

[0004] However, when the existing transfer equipment for the production of large construction machinery is transported on the production line, most of them adopt a gantry structure for linear transportation, and a corresponding winch and traction rope are arranged on the gantry, and a positioning structure is arranged at the end of the traction rope to transport the components of large construction machinery equipment. However, due to the large weight of these components of large construction machinery equipment, the gantry is prone to generate a lateral pulling force on the traction rope due to inertia when starting, and then the components of the construction machinery equipment will swing back and forth at the beginning of the conveying start of the gantry, thus generating certain safety hazards and affecting the safe production work of the equipment. In view of this, we have proposed a transfer device for the production of large construction machinery. Summary of the Invention

[0005] The purpose of the present invention is to provide a transfer device for the production of large construction machinery to solve the problems raised in the above background technique.

[0006] To achieve the above object, the present invention provides the following technical solution: A transfer device for the production of large construction machinery, including a top frame, on the upper surface of which a winch is fixedly installed. The output end of the winch is fixedly installed with a winding column, around the arc-shaped outer wall of which a traction rope is wound. The end of the traction rope is fixedly connected to a transfer frame. A traction port is opened on the inner wall of the top frame. The lower surface of the top frame is fixedly installed with support columns, and the bottom ends of the support columns are fixedly installed with a moving platform.

At the bottom of the installation plate, there is a swing-back assembly that can prevent the traction rope from swinging back and forth during the transfer of large construction machinery, and a backstop assembly that can prevent the swing-back assembly from being damaged by the impact of the traction rope.

[0007] Preferably, the U-shaped frame is fixedly installed on the lower surface of the installation plate. A guiding wheel is rotatably installed on the side wall of the U-shaped frame.

A swing-back rod is hinged on the side wall of the U-shaped frame. A guiding groove is opened on the inner wall of the swing-back rod. A swing-back wheel is rotatably installed at the end of the swing-back rod far from the U-shaped frame. On the arc-shaped outer wall of the swing-back wheel, there is a deceleration assembly that can suppress the rebound speed of the approaching traction rope. Inside the swing-back wheel, there is a locking assembly that can prompt the deceleration claw to actively press against the traction rope and decelerate it.

[0008] Preferably, an annular arc groove adapted to the traction rope is opened on the arc-shaped outer surface of the guiding wheel, and in the initial state, the traction rope is inside the annular arc groove. An annular groove adapted to the outer diameter of the traction rope is opened on the arc-shaped outer wall of the contact wheel, and the contact wheel is pressed against the outer surface of the traction rope. When the traction rope swings horizontally due to the inertia of the hoisting equipment, the bent traction rope will generate a horizontal thrust on the contact wheel.

[0009] Preferably, the guiding column is arranged inside the guiding groove, and the guiding column is adapted to the guiding groove. At the same time, an annular arc groove with a diameter larger than that of the traction rope is opened on the arc-shaped outer wall of the swing-back wheel, so that when the swing-back wheel rotates with the swing-back rod and contacts the traction rope, the traction rope will not be offset.

[0010] Preferably, a rectangular groove is formed at the center of the mounting plate. The anti-retreat component includes a connecting beam, and the connecting beam is fixedly installed on the inner wall of the rectangular groove. A limiting tooth is fixedly installed on the side wall of the swing rod. An articulated plate is hinged to the lower surface of the mounting plate. A limiting block is fixedly installed at one end of the articulated plate away from the mounting plate. A sleeve is hinged to the lower surface of the connecting beam. A sliding rod is slidably installed on the inner wall of the bottom end of the sleeve. A pressing spring is fixedly connected between the top end of the sliding rod and the inner wall of the sleeve. One end of the sliding rod away from the sleeve is hinged to the upper surface of the articulated plate.

[0011] Preferably, a rounded corner is provided at the bottom edge of the limiting block so that the limiting block can be inserted obliquely into the gap between the limiting teeth. A sliding hole with a diameter adapted to the outer diameter of the sliding rod is formed inside the sleeve, and the top end of the pressing spring is fixedly connected to the inner wall of the top end of the sliding hole.

[0012] Preferably, the deceleration component includes a rotating rod, and the rotating rod is rotatably installed on the inner wall of the swing wheel. The rotating rod penetrates and is fixedly connected with a deceleration claw. A scroll spring is sleeved on the arc-shaped outer wall of the rotating rod. A contact cavity is formed on the inner surface of one end of the deceleration claw away from the rotating rod. A round rod is rotatably installed on the inner wall of the contact cavity. The round rod penetrates and is fixedly installed with a contact column. A coil spring is sleeved on the arc-shaped outer wall of the round rod.

[0013] Preferably, the number of the contact columns is multiple, and the multiple contact columns are evenly distributed in an arc array inside the contact cavity. Multiple convex ridges are provided on the arc-shaped outer wall of the contact column to increase the friction coefficient when the contact column contacts the outer surface of the traction rope.

[0014] Preferably, the locking component includes a transmission cavity, and the transmission cavity is formed on the inner wall of the swing wheel. A transmission plate is slidably installed on the inner wall of the transmission cavity. An arc-shaped plate is fixedly connected to the outer wall of one side of the transmission plate away from the center of the swing wheel. A return spring is fixedly installed on the outer wall of one side of the transmission plate close to the center of the swing wheel. An articulated rod is hinged to the side wall of the transmission plate. The rotating rod penetrates and is fixedly installed with a disc.

[0015] Preferably, the number of the discs is two, and the two discs are arranged mirror-symmetrically at the left and right ends of the rotating rod, so as to cooperate with the articulated rod to make the movement of the transmission plate more stable. The size of the transmission plate is adapted to the transmission cavity, and a rubber pad is provided at the edge of the transmission plate, so that the transmission plate moves at a slower speed when sliding along the inner wall of the transmission cavity under the influence of the elastic force of the return spring. The hinge point between the articulated rod and the disc is located at a position where the disc deviates from the axis, so that the sliding of the transmission plate can drive the disc to rotate in cooperation with the articulated rod.

[0016] Compared with the prior art, the present invention provides a transfer device for the production of large construction machinery, which has the following beneficial effects: 1. For the transfer device for the production of large construction machinery, by providing a swing-back assembly, the traction rope that is bent during transportation due to inertia will generate a lateral thrust on the contact wheel. At this time, the contact wheel will move downward along the outer surface of the traction rope. At the same time, the sleeve plate and the sliding plate will deflect away from the traction rope side with the hinge point between the sleeve plate and the mounting plate as the rotation center. At this time, when the guiding column makes a circular motion with the sleeve plate, it will move downward in the vertical direction, and then cooperate with the guiding groove to drive the swing-back rod to swing toward the traction rope side with the hinge point between it and the U-shaped frame as the rotation center, so as to prompt the swing-back wheel to accelerate contact with and adhere to the traction rope, preventing the traction rope from swinging significantly laterally due to inertia when lifting large construction machinery and equipment, which affects the transfer and lifting safety of the equipment.

[0017] 2. For the transfer device for the production of large construction machinery, by providing a anti-retreat assembly, when the swing-back rod gradually swings toward the traction rope side due to the back-and-forth swing of the traction rope, driven by the close-fitting spring, the sliding rod drives the bottom end of the hinge plate and the limiting block to tightly fit on the side of the swing-back rod. At this time, since a triangular structure is formed among the swing-back rod, the hinge plate and the mounting plate, and another set of triangular structures are formed between the combination of the sleeve and the sliding rod and between the hinge plate and the mounting plate. At the same time, through the setting of a number of limiting teeth, the swing-back rod will not retreat when swinging toward the traction rope side, so that the traction rope will gradually become stable during the lifting process, ensuring the stability and safety of the lifting process of large construction machinery.

[0018] 3. For the transfer device for the production of large construction machinery, by providing a deceleration assembly, when the traction rope moves away from the swing-back wheel due to inertia, the surface of the traction rope will come into contact with the inner surface of the deceleration claw and the outer surfaces of multiple contact columns. At this time, affected by the elastic force of the coil spring, while not limiting the traction rope, a contact deceleration is performed on the traction rope, so as to prompt the swing of the traction rope in the horizontal direction to gradually become stable, ensuring the stability and safety of the transfer frame fixed at the bottom of the traction rope and large construction machinery and equipment during the transfer process.

[0019] 4. The transfer device for the production of large-scale engineering machinery is provided with a locking assembly. When the traction rope is close to the curved outer wall of the return-swing wheel and finally contacts and presses against the curved plate, the transmission plate is resisted by the curved plate and slides along the inner wall of the transmission cavity toward the center of the return-swing wheel. At this time, the hinged rod is driven to cause the disc to rotate with the rotating rod as the rotation center, thereby driving the deceleration claw to swing toward the center of the return-swing wheel to grasp the traction rope, thereby preventing the traction rope from quickly detaching from the return-swing wheel and swinging back and forth, which in turn causes the transfer frame and large-scale engineering machinery equipment at the bottom to shake violently, resulting in safety hazards, so as to ensure the safety and stability of the equipment transportation process.

[0023] In an embodiment of the present invention, the U-shaped frame 111 is fixedly installed on the lower surface of the mounting plate 15. A guiding wheel 112 is rotatably installed on the side wall of the U-shaped frame 111. A sleeve plate 113 is hinged to the lower surface of the mounting plate 15. The inner wall of one end of the sleeve plate 113 away from the mounting plate 15 is slidably connected with a sliding plate 114. A connecting spring 115 is fixedly connected between the sliding plate 114 and the inner wall of the sleeve plate 113. A contact wheel 116 is rotatably connected to one end of the sliding plate 114 away from the connecting spring 115. A guiding column 117 is fixedly installed on the side wall of the sleeve plate 113. A swing-back rod 118 is hinged to the side wall of the U-shaped frame 111. A guiding groove 119 is formed in the inner wall of the swing-back rod 118. A swing-back wheel 1110 is rotatably installed at one end of the swing-back rod 118 away from the U-shaped frame 111.

[0024] Please refer to the attached drawings of the specification Figures 1 - 2 Specifically, the number of the support columns 7 is set to four, and the four support columns 7 are arranged in two groups mirror-symmetrically on the left and right sides of the vertical central axis of the top frame 1, so as to form a stable support structure on the left and right sides of the top frame 1. At the same time, the hydraulic cylinder 10 is arranged on the side of the moving wheel 9, and a contact flat plate is arranged at the bottom end of the hydraulic cylinder 10, so that when the hydraulic cylinder 10 starts to extend, the contact flat plate finally fits on the ground, making the whole device stable on the ground, and thus facilitating the production and processing of large construction machinery components. In addition, auxiliary plates are arranged at both ends of the top frame 1, and one end of the winding column 3 away from the winch 2 is rotatably connected to the auxiliary plate, so that both ends of the winding column 3 itself can receive good support effects, avoiding bending and damage due to the lifting of large construction machinery components, which affects the lifting effect of the winch 2 on the transported materials. Specifically, a corresponding hoisting and fixing structure is arranged at the bottom of the transfer frame 5 to fix the material to be transferred through the transfer frame 5, and then the traction rope 4 can drive the transfer frame 5 and the transferred material to rise or fall under the drive of the winch 2, so as to complete the processing operation of large construction machinery components. Further, the mounting plate 15 is arranged at the vertical central axis of the traction port 6, and a rectangular groove is formed at the center of the mounting plate 15, so that the traction rope 4 can pass through the rectangular groove and then be connected to the transfer frame 5, so as to cooperate with the swing-back assembly 11 to protect the traction rope 4 during the transfer process of large construction machinery equipment.

[0025] In addition, please refer to the attached drawings of the specification Figures 3 - 6, in the embodiment of the present invention, the number of U-shaped frames 111 is set to two groups, and the two groups of U-shaped frames 111 are symmetrically arranged with respect to the vertical central axis of the mounting plate 15, so as to provide a stable supporting effect for the guide wheel 112. At the same time, an annular arc groove adapted to the traction rope 4 is formed on the arc-shaped outer surface of the guide wheel 112, and in the initial state, the traction rope 4 is located inside the annular arc groove, so that the traction rope 4 is always subjected to the pressing effect of the guide wheel 112 on the side during use without affecting the winding or unwinding of the traction rope 4 in the vertical direction. Further, a connection groove adapted to the end of the sliding plate 114 is formed on the inner wall of the sleeve plate 113, and the sliding plate 114 is slidably installed inside the connection groove. Specifically, the top end of the connection spring 115 is fixedly connected to the top inner wall of the connection groove, and an annular groove adapted to the outer diameter of the traction rope 4 is formed on the arc-shaped outer wall of the contact wheel 116, and the contact wheel 116 is pressed against the outer surface of the traction rope 4. When the traction rope 4 swings laterally due to the inertia of the hoisting equipment, the bent traction rope 4 will generate a lateral thrust on the contact wheel 116. At this time, the contact wheel 116 will move downward along the outer surface of the traction rope 4, and at the same time, the sleeve plate 113 and the sliding plate 114 will deflect away from the traction rope 4 with the hinge point between the sleeve plate 113 and the mounting plate 15 as the rotation center. At this time, when the guide post 117 makes a circular motion along with the sleeve plate 113, it will move downward in the vertical direction, and then cooperate with the guide groove 119 to drive the swing rod 118 to swing toward the traction rope 4 with the hinge point between it and the U-shaped frame 111 as the rotation center, so as to prompt the swing wheel 1110 to accelerate contact with and stick to the traction rope 4, preventing the traction rope 4 from swinging greatly laterally due to inertia when hoisting large-scale engineering machinery and equipment, which affects the transfer and hoisting safety of the equipment.

[0026] Further, the guide post 117 is arranged inside the guide groove 119, and the guide post 117 is adapted to the guide groove 119. At the same time, an annular arc groove with a diameter larger than that of the traction rope 4 is formed on the arc-shaped outer wall of the swing wheel 1110, so that when the swing wheel 1110 rotates along with the swing rod 118 and contacts the traction rope 4, the traction rope 4 will not be offset, avoiding the situation that the traction rope 4 drives the transfer frame 5 and the transferred materials to swing left and right. At the same time, the number of the sleeve plate 113, the sliding plate 114, the connection spring 115, the guide post 117 and the swing rod 118 is set to two groups, and the two groups of the sleeve plate 113, the sliding plate 114, the connection spring 115, the guide post 117 and the swing rod 118 are symmetrically arranged with respect to the vertical central axis of the mounting plate 15, so that the transmission of the contact wheel 116 is more stable, and at the same time, the swing wheel 1110 generates a more stable swing limiting effect on the traction rope 4, thereby ensuring the stability of the transfer process of large-scale engineering machinery and equipment and reducing the occurrence of safety accidents.

[0027] Please refer to the attached instructions Figures 3 - 6, in an embodiment of the present invention, a backstop component 12 is provided at the bottom of the mounting plate 15 to prevent the swing-back component 11 from being damaged by the impact of the towing rope 4. The backstop component 12 includes a connecting beam 121, and the connecting beam 121 is fixedly installed on the inner wall of the rectangular groove. A limiting tooth 122 is fixedly installed on the side wall of the swing-back rod 118. A hinge plate 123 is hinged to the lower surface of the mounting plate 15. A limiting block 124 is fixedly installed at one end of the hinge plate 123 away from the mounting plate 15. The lower surface of the connecting beam 121 is hinged to a sleeve 125. A sliding rod 126 is slidably installed on the inner bottom wall of the sleeve 125. A pressing spring 127 is fixedly connected between the top end of the sliding rod 126 and the inner wall of the sleeve 125. The end of the sliding rod 126 away from the sleeve 125 is hinged to the upper surface of the hinge plate 123.

[0028] Specifically, the number of the connecting beams 121 is set to two groups, and the two groups of connecting beams 121 are symmetrically arranged with the vertical central axis of the rectangular groove as the symmetry axis, so that the two hinge plates 123 corresponding to the two groups of connecting beams 121 can stably stop the swing-back rods 118 on the left and right sides of the swing-back wheel 1110, so that the swing-back wheel 1110 is more stable when contacting the towing rope 4. In addition, a fillet is provided at the bottom edge of the limiting block 124, so that the limiting block 124 can be inserted into the gap between the limiting teeth 122 in an inclined shape, and at the same time, the limiting block 124 will not cause the swing-back rod 118 to be stuck. Further, a sliding hole with a diameter adapted to the outer diameter of the sliding rod 126 is opened inside the sleeve 125, and the top end of the pressing spring 127 is fixedly connected to the inner wall of the top end of the sliding hole. Thus, when the device is in use, the bottom end of the hinge plate 123 and the limiting block 124 are in the middle of the side surface of the swing-back rod 118, so that a triangular structure is formed among the swing-back rod 118, the hinge plate 123 and the mounting plate 15. At the same time, a combined body of the sleeve 125 and the sliding rod 126 and the hinge plate 123 and the mounting plate 15 form another triangular structure, so that the swing-back rod 118 can receive a more stable supporting force when driving the swing-back wheel 1110 to contact the laterally swinging towing rope 4. And when the towing rope 4 swings back and forth and causes the swing-back rod 118 to gradually swing closer to the side of the towing rope 4, driven by the pressing spring 127, the sliding rod 126 drives the bottom end of the hinge plate 123 and the limiting block 124 to closely fit on the side surface of the swing-back rod 118. At the same time, through the arrangement of a plurality of limiting teeth 122, the swing-back rod 118 will not retreat when swinging towards the side of the towing rope 4, so that the towing rope 4 will gradually tend to be stable during the hoisting process, so as to ensure the stability and safety of the hoisting process of large construction machinery.

[0029] Please refer to the attached drawings of the specification Figures 7 - 10, a deceleration component 13 for suppressing the rebound speed of the traction rope 4 close thereto is provided on the arc-shaped outer wall of the pendulum wheel 1110. The deceleration component 13 includes a rotating rod 131 rotatably installed on the inner wall of the pendulum wheel 1110. The rotating rod 131 penetrates and is fixedly connected to a deceleration claw 132. A scroll spring 133 is sleeved on the arc-shaped outer wall of the rotating rod 131. A contact cavity 134 is formed on the inner surface of the end of the deceleration claw 132 far from the rotating rod 131. A round rod 135 is rotatably installed on the inner wall of the contact cavity 134. The round rod 135 penetrates and is fixedly installed with a contact column 136. A coil spring 137 is sleeved on the arc-shaped outer wall of the round rod 135.

[0030] In addition, a swing groove with a width adapted to the deceleration claw 132 is formed on the arc-shaped outer wall of the pendulum wheel 1110, and the deceleration claw 132 is movably installed inside the swing groove. At the same time, the deceleration claw 132 is arc-shaped, and the number of the deceleration claws 132 is set to be several groups. At the same time, several groups of deceleration claws 132 are evenly distributed in a mirror circumferential array on the left and right sides of the pendulum wheel 1110, so that when the pendulum wheel 1110 and the traction rope 4 approach each other, the traction rope 4 can be contacted. Due to its arc-shaped setting, the deceleration claw 132 will not cause the traction rope 4 to be stuck. At the same time, the traction rope 4 can also pass through the deceleration claw 132 and finally fit onto the arc-shaped outer surface of the pendulum wheel 1110. And when the traction rope 4 breaks away from the pendulum wheel 1110 due to inertia, the two deceleration claws 132 will also decelerate the return of the traction rope 4, thereby reducing the movement tendency of the traction rope 4 to shake repeatedly in the horizontal direction, so as to promote the traction rope 4 to finally tend to be stable.

[0031] Further, circular holes with a diameter larger than the outer diameter of the scroll spring 133 are formed on the inner walls on both sides of the swing groove, and both ends of the scroll spring 133 are fixedly connected to the arc-shaped outer wall of the rotating rod 131 and the bottom inner wall of the circular hole respectively, so that the rotating rod 131 always has a reverse rotation tendency to reset when driving the deceleration claw 132 to rotate. In addition, multiple sets of contact columns 136 are provided, and the multiple sets of contact columns 136 are evenly distributed in an arc array inside the contact cavity 134, and multiple sets of convex ribs are provided on the arc-shaped outer wall of the contact column 136 to increase the friction coefficient when the contact column 136 contacts the outer surface of the traction rope 4. At the same time, holes with a diameter larger than the outer diameter of the coil spring 137 are formed on the upper and lower inner walls of the contact cavity 134, and both ends of the coil spring 137 are respectively on the arc-shaped outer wall of the round rod 135 and the bottom inner wall of the above-mentioned hole, so that when the round rod 135 drives the contact column 136 to rotate, affected by the elastic force of the coil spring 137, the round rod 135 drives the contact column 136 to always have a reverse rotation tendency to reset. Furthermore, when the traction rope 4 moves away from the pendulum wheel 1110 due to inertia, the surface of the traction rope 4 will contact the inner surface of the deceleration claw 132 and the outer surfaces of multiple sets of contact columns 136. At this time, affected by the elastic force of the coil spring 137, while not limiting the traction rope 4, the traction rope 4 is decelerated by contact, so as to promote the swing of the traction rope 4 in the horizontal direction to gradually become stable, so as to ensure the stability and safety of the transfer frame 5 fixed at the bottom of the traction rope 4 and the large engineering machinery and equipment during the transfer process.

[0032] Further, please refer to the attached drawings of the specification Figures 8 - 10 In the embodiment of the present invention, a locking assembly 14 for prompting the deceleration claw 132 to actively stick to the traction rope 4 and decelerate it is provided inside the pendulum wheel 1110. The locking assembly 14 includes a transmission cavity 141, the transmission cavity 141 is formed on the inner wall of the pendulum wheel 1110, a transmission plate 142 is slidably installed on the inner wall of the transmission cavity 141, an arc-shaped plate 143 is fixedly connected to the outer wall of the transmission plate 142 on the side away from the center of the pendulum wheel 1110, a return spring 144 is fixedly installed on the outer wall of the transmission plate 142 on the side close to the center of the pendulum wheel 1110, and a hinge rod 145 is hinged to the side wall of the transmission plate 142. The rotating rod 131 passes through and is fixedly installed with a disc 146.

[0033] It is worth noting that there are multiple sets of locking assemblies 14, and the multiple sets of locking assemblies 14 are evenly distributed on the arc-shaped outer wall of the swing wheel 1110 in a circular array, and the number of locking assemblies 14 corresponds to the number of deceleration assemblies 13. At the same time, there are two sets of discs 146, and the two sets of discs 146 are mirror-imaged at the left and right ends of the rotating rod 131, so as to cooperate with the hinge rod 145 to make the movement of the transmission plate 142 more stable. In addition, the size of the transmission plate 142 is adapted to the transmission cavity 141, and the transmission plate A rubber pad is provided at the edge of 142, so that the transmission plate 142 maintains a slow speed when sliding along the inner wall of the transmission cavity 141 under the influence of the elastic force of the reset spring 144, and will not reset quickly, so that the deceleration claw 132 still maintains a gripping posture when the traction rope 4 quickly breaks away from the contact with the arc-shaped outer surface of the return swing wheel 1110, thereby achieving a deceleration effect on the traction rope 4. Further, the curvature of the arc plate 143 is the same as that of the return swing wheel 1110, and a The arc-shaped outer wall of the swing wheel 1110 is provided with a through groove adapted to the above-mentioned rectangular column to ensure the stability of the arc-shaped plate 143 and the swing wheel 1110 when relative motion occurs. At the same time, the hinge point between the hinge rod 145 and the disc 146 is located at the position where the disc 146 deviates from the axis, so that when the traction rope 4 approaches the arc-shaped outer wall of the swing wheel 1110 and finally contacts and presses against the arc-shaped plate 143, the transmission plate 142 is resisted by the arc-shaped plate 143 and moves along the inner wall of the transmission cavity 141. The center of the swing wheel 1110 slides to one side, and at this time, the hinged rod 145 drives the disc 146 to rotate with the rotating rod 131 as the rotation center, thereby driving the deceleration claw 132 to swing toward the center of the swing wheel 1110 to grasp the traction rope 4, thereby preventing the traction rope 4 from quickly detaching from the swing wheel 1110 and swinging back and forth, thereby causing the transfer frame 5 at the bottom and the large-scale engineering machinery equipment to shake violently, causing safety hazards, so as to ensure the safety and stability of the equipment transportation process.

[0034] In the present invention, during use, by starting the winch 2 and cooperating with the rotation of the winding column 3, the towing rope 4 is unwound until the transfer frame 5 descends to the target position. The staff fixes the large-scale engineering machinery and equipment to the transfer frame 5. After all the fixings are completed, by controlling the winch 2, the winding column 3 is driven to rotate in reverse, thereby winding the towing rope 4 to lift the transfer frame 5 and the large-scale engineering machinery and equipment fixed to its bottom. Until it is lifted to the transfer height, the hydraulic column 10 is controlled by the driving device to contract. Finally, the bottom of the moving wheel 9 contacts the ground. Then the driving device controls the rotation of the moving wheel 9, so that the entire device moves linearly. Finally, the large-scale engineering machinery and equipment are transported to the next processing location to complete the subsequent processing operations. During the transfer process, due to inertia, the towing rope 4 may undergo lateral offset and sway at the beginning of the transfer process. By providing a pendulum assembly 11, the bent towing rope 4 will generate a lateral thrust on the contact wheel 116. At this time, the contact wheel 116 will move downward along the outer surface of the towing rope 4. At the same time, the sleeve plate 113 and the sliding plate 114 will deflect away from the towing rope 4 with the hinge point between the sleeve plate 113 and the mounting plate 15 as the rotation center. At this time, when the guiding column 117 makes a circular motion with the sleeve plate 113, it will move downward in the vertical direction, and then cooperate with the guiding groove 119 to drive the pendulum rod 118 to swing toward the towing rope 4 with the hinge point between it and the U-shaped frame 111 as the rotation center, so as to prompt the pendulum wheel 1110 to accelerate contact with and stick to the towing rope 4, preventing the towing rope 4 from swinging significantly laterally due to inertia when hoisting large-scale engineering machinery and equipment, which affects the transfer and hoisting safety of the equipment.

[0035] The above has generally described the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
