Description

Technical Field

[0001] The present invention relates to the technical field of traction machinery, and in particular to traction using a steel wire rope, and specifically refers to a steel wire rope traction mechanism with adjustable traction position and direction and a use method thereof. Background Art

[0002] In the agricultural and construction operations, winches and other equipment are usually used to tow or lift heavy objects and trailers. When the winch drum rotates, the wire rope is wound around it to pull the heavy object or trailer upward, and when the rope is let out, a certain pulling force is provided to the heavy object or trailer to control the downward movement speed of the heavy object or trailer.

[0003] At present, in wire rope traction operations, a fixed traction method is usually used. The wire rope can only provide traction in one direction, which is difficult to cover a large operating range and has obvious limitations in the actual operation process. Once the operating position of the towed trailer changes, it is necessary to move the bulky mechanical equipment many times and repeatedly adjust the traction position. This process not only leads to a large consumption of manpower and material resources, greatly increases the operation cost, but also seriously hinders the overall operation progress, resulting in extremely low operation efficiency. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a wire rope traction mechanism with adjustable traction position and direction and a method of use, which can realize left and right movement of the wire rope and up and down swing of the traction frame to adapt to changes in traction direction and traction position and cover a larger working area.

[0005] The present invention is realized by the following technical scheme, which provides a wire rope traction mechanism with adjustable traction position and direction, comprising a frame, a traction frame mounted on the frame, and a pulley seat I rotatably connected to the traction frame through a first vertical axis, wherein the pulley seat I is rotatably connected to a pulley I; a transverse guide shaft and a driving mechanism are mounted on the traction frame, a sliding sleeve is slidably provided on the transverse guide shaft, the driving mechanism drives the sliding sleeve to move along the transverse guide shaft, the sliding sleeve is rotatably connected to a pulley seat II located in front of the pulley I through a second vertical axis, the pulley seat II is rotatably connected to a pulley II, and the axes of the pulley I and the pulley II both extend in the transverse direction; the wire rope extends forward through the wheel groove of the pulley I and the wheel groove of the pulley II in sequence.

[0006] The setting of this solution enables the pulley seat I to rotate around the vertical axis of the first vertical shaft, so as to cooperate with the left - right horizontal movement of the sliding seat. By using the left - right horizontal movement of the sliding sleeve, the traction position of the steel wire rope can be adjusted. At the same time, the pulley seat II can rotate around the vertical axis of the second vertical shaft, and the pulley seat II can move left - right horizontally along with the sliding sleeve, so as to cooperate with the left - right movement of the sliding sleeve to realize the adjustment of the traction direction, increase the operation range, and finally meet the requirements of the left - right movement of the towed trailer.

[0007] As an optimization, two pulley IIIs are also rotatably connected to the sliding sleeve and are located between pulley I and pulley II. The axes of the two pulley IIIs both extend vertically, and the grooves of the two pulley IIIs are arranged oppositely to form a perforation adapted to the steel wire rope. The steel wire rope extends forward through the groove of pulley I, the perforation, and the groove of pulley II in sequence. This optimized solution forms a perforation through the grooves of the two pulley IIIs to form a fulcrum for laterally pushing the steel wire rope, and reduces the friction when the steel wire rope is wound or unwound and moved. At the same time, through the formed perforation, when the sliding sleeve does not move, the direction of the steel wire rope between pulley I and pulley III can be kept unchanged.

[0008] As an optimization, pulley II is located on the side of pulley seat II away from pulley I. After the steel wire rope passes through the perforation, it extends forward through the bottom groove of pulley II. The position setting of pulley II in this optimized solution is beneficial to increasing the distance between pulley I and pulley II, thereby increasing the acting range on the steel wire rope along its length direction, being beneficial to increasing the covered operation area of the traction mechanism, using the bottom groove of pulley II to provide a lateral thrust to the steel wire rope, being convenient for reducing the height, and being suitable for towing a trailer moving on a slope.

[0009] As an optimization, a "[“ - shaped plate with an opening facing down is provided at the top of the sliding sleeve. The two side plates of the "[“ - shaped plate are fixedly connected to the sliding sleeve, and a space for installing pulley III is formed between the top plate of the "[“ - shaped plate and the sliding sleeve. The upper end of the axle of pulley III is rotatably connected to the top plate of the "[“ - shaped plate. This optimized solution provides an installation space and support for pulley III by setting the "[“ - shaped plate, and the structure is simple.

[0010] As an optimization, a second vertical shaft extending upward is fixedly connected to the top plate of the "[“ - shaped plate. The pulley seat II is sleeved on the second vertical shaft and is rotatably connected to the second vertical shaft. This optimized solution provides support for the second vertical shaft through the "[“ - shaped plate, and due to the setting of the "[“ - shaped plate, pulley III is lower than pulley seat II in the height direction, which is more beneficial to reducing the height of the steel wire rope.

[0011] As an optimization, the pulley seat I is hinged with a first bracket through a transverse hinge shaft, and the first bracket is fixed with a guide anti-dropout sleeve I located in front of the pulley I, and a guide hole for the wire rope to pass through is opened on the guide anti-dropout sleeve I. This optimization scheme can prevent the wire rope from falling off the pulley I by setting the guide anti-dropout sleeve I, and by setting the first bracket, the up and down swing of the first bracket is used to better adapt to the up and down angle change of the wire rope when the sliding sleeve moves left and right.

[0012] As an optimization, a second bracket is hinged on the pulley seat II through a transverse hinge shaft, and a guide anti-drop sleeve II is fixed on the second bracket and located in front of the pulley II. A guide hole for the wire rope to pass through is opened on the guide anti-drop sleeve II. This optimization scheme can prevent the wire rope from escaping from the pulley II by setting the guide anti-drop sleeve II, and adapt to the change of the height of the wire rope by swinging the second bracket up and down.

[0013] As an optimization, the traction frame is hinged to the frame through a transverse rotating shaft, and the transverse rotating shaft is located at the rear end of the traction frame. The traction frame of this optimization solution can swing around the axis of the transverse rotating shaft, so that when the traction distance changes, the angle between the wire rope and the ground can be adjusted.

[0014] The present invention also provides a method for using a wire rope traction mechanism with adjustable traction position and direction, comprising the following steps: a. When towing a trailer moving upward along a slope, install the wire rope traction mechanism at the top of the slope, and the winch is located behind the wire rope traction mechanism. The wire rope of the winch passes through the top wheel groove of pulley I, the through hole, and the bottom wheel groove of pulley II in sequence, and then extends toward the trailer and is connected to the trailer; b. When the trailer needs to move horizontally, the driving mechanism pushes the sliding sleeve to move horizontally, and the pulley seat I and the pulley seat II rotate accordingly to adjust the pulling direction and position of the wire rope; c. When the trailer moves laterally but the driving mechanism does not move, the holes formed by the two pulleys III are used as fulcrums to limit the lateral movement of the wire rope, so that the direction of the wire rope between pulleys I and III remains unchanged, and the traction direction of the wire rope is changed by the rotation of the pulley seat II to increase the lateral traction range; d. When the traction distance changes, the traction frame swings up and down around the hinge point between it and the frame to adjust the angle between the wire rope and the ground.

[0015] The beneficial effects of the present invention are as follows: the sliding sleeve is driven to move left and right by the driving mechanism, so that the traction position is adjusted; the traction direction is adjusted by setting a pulley seat II that rotates around a vertical axis; and the angle between the wire rope and the ground can be adjusted by the up and down swinging of the traction frame, so that a larger working area can be covered.

[0017] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.

[0018] like Figure 1 The wire rope traction mechanism with adjustable traction position and direction comprises a frame 1, a traction frame 5 installed on the frame 1, and a pulley seat Ⅰ2 rotatably connected to the traction frame through a first vertical axis, and a pulley Ⅰ3 rotatably connected to the pulley seat Ⅰ2.

[0019] The traction frame 5 adopts a frame structure, and the traction frame 5 is hinged to the frame through a transverse rotating shaft, and the transverse rotating shaft is located at the rear end of the traction frame. Specifically, the traction frame is fixedly provided with a transverse rotating shaft extending horizontally left and right, and the frame is fixedly provided with a shaft sleeve. The transverse rotating shaft passes through the inner hole of the shaft sleeve and is rotatably connected to the shaft sleeve. The traction frame can swing up and down around the axis of the transverse rotating shaft.

[0020] An upwardly extending fixed sleeve 16 is fixed on the frame, the upper end of the first vertical axis is fixedly connected to the pulley seat Ⅰ2, the lower end of the first vertical axis extends downward into the fixed sleeve, and the first vertical axis and the fixed sleeve are rotatably connected through a bearing, and the pulley seat Ⅰ2 can swing left and right around the axis of the first vertical axis.

[0021] A first bracket 15 is hingedly connected to the pulley seat I through a transverse hinge shaft, and a guide anti-drop sleeve I4 is fixedly arranged in front of the pulley I on the first bracket 15, and a guide hole for the steel wire rope to pass through is opened on the guide anti-drop sleeve I4. The guide anti-drop sleeve I4 of this embodiment is arranged obliquely downward, and the steel wire rope extends in an oblique downward direction after passing through the guide hole.

[0022] A transverse guide shaft 13 and a driving mechanism 8 are installed on the traction frame 5. The axis of the transverse guide shaft extends in the left-right direction, and the transverse guide shaft is fixed to the front end of the traction frame, increasing the distance between the transverse guide shaft and the swing axis of the traction frame, thereby facilitating increasing the up and down adjustment distance of the wire rope when the traction frame swings up and down, and also facilitating increasing the control range of the wire rope along the length direction of the wire rope.

[0023] A sliding sleeve 7 is slidably provided on the transverse guide shaft 13, and the driving mechanism drives the sliding sleeve 7 to move along the transverse guide shaft, thereby adjusting the traction position of the wire rope. The driving mechanism 8 of this embodiment is a hydraulic cylinder arranged transversely, the axis of the hydraulic cylinder is parallel to the axis of the transverse guide shaft, the cylinder body of the hydraulic cylinder is fixedly connected to the traction frame, and the piston rod of the hydraulic cylinder is fixedly connected to the sliding sleeve. The piston rod of the hydraulic cylinder of this embodiment is fixedly connected to the sliding sleeve through a transmission rod, one end of the transmission rod is fixedly connected to the sliding sleeve, and the other end is fixedly connected to the extended end of the piston rod. When the piston rod of the hydraulic cylinder is extended or retracted, the transmission force of the transmission rod is used to drive the sliding sleeve to move.

[0024] The sliding sleeve is rotatably connected to a pulley seat II10 located in front of pulley I3 via a second vertical axis, and a pulley II11 is rotatably connected to the pulley seat II10. The axes of the pulley I3 and the pulley II11 extend horizontally; the wire rope 14 extends forward through the wheel groove of the pulley I and the wheel groove of the pulley II in sequence.

[0025] The sliding sleeve 7 is also rotatably connected to two pulleys III9 located between the pulley I3 and the pulley II11. The axes of the two pulleys III9 extend vertically. The two pulleys III are distributed along the sliding direction of the sliding sleeve, and the wheel grooves of the two pulleys III are relatively arranged to form through holes adapted to the wire rope. The wire rope extends forward through the wheel groove of pulley I, the through hole, and the wheel groove of pulley II in sequence.

[0026] The pulley II is located on the side of the pulley seat II away from the pulley I. After the steel wire rope passes through the through hole, it extends forward through the bottom groove of the pulley II. When the pulley II swings with the pulley seat II, the steel wire rope is pushed by the groove. Specifically, two opposite connecting ear plates are fixed on the front side of the pulley seat II, and the pulley II is located between the two connecting ear plates.

[0027] A "["-shaped plate 18 with an opening facing downward is provided on the top of the sliding sleeve. The two side plates of the "["-shaped plate 18 are fixedly connected to the sliding sleeve 7. A space for installing the pulley III is formed between the top plate of the "["-shaped plate and the sliding sleeve. The upper end of the axle of the pulley III is rotatably connected to the top plate of the "["-shaped plate. The upper end of the axle of the pulley III can also be fixedly connected to the top plate of the "["-shaped plate, and the wheel body of the pulley III is rotatably connected to its axle through a bearing. As long as the wire rope comes into contact with the pulley III, the pulley III can rotate accordingly to reduce the friction between the wire rope and the pulley III.

[0028] A second vertical axis 17 extending upward is fixedly connected to the top plate of the “[”-shaped plate. The pulley seat Ⅱ10 is sleeved on the second vertical axis 17 and is rotatably connected to the second vertical axis. The pulley seat Ⅱ10 can swing left and right around the axis of the second vertical axis to adjust the traction direction of the wire rope.

[0029] A second bracket 19 is hinged on the pulley seat II through a transverse hinge shaft, and a guide anti-drop sleeve II 12 is fixedly provided on the second bracket and is located in front of the pulley II. A guide hole for the wire rope to pass through is opened on the guide anti-drop sleeve II, and the axis of the guide hole of the guide anti-drop sleeve II extends in the front-to-back direction and is perpendicular to the axis of the pulley II.

[0030] The steel wire rope 14 drawn by the winch 6 passes through the pulley Ⅰ3, the guide anti-drop sleeve Ⅰ4, the pulley Ⅲ9, the pulley Ⅱ11 and the guide anti-drop sleeve Ⅱ12 in turn to pull the operation device. When the pulling position and direction of the steel wire rope 14 need to be adjusted, the hydraulic cylinder pushes the sliding sleeve 7, the pulley Ⅲ9, the pulley seat Ⅱ10, the pulley Ⅱ11 and the guide anti-drop sleeve Ⅱ12 to move horizontally; under the traction force of the steel wire rope 14, the pulley seat Ⅱ10 rotates and the guide anti-drop sleeve Ⅱ12 swings to follow the direction of the steel wire rope 14 and prevent the steel wire rope from slipping on the pulley Ⅱ11 groove; the grooves of the two pulleys Ⅲ installed side by side on the upper part of the sliding sleeve 7 form a closed space to prevent the steel wire rope 14 from slipping on the grooves of the two pulleys Ⅲ; the lateral adjustment of the steel wire rope 14 will drive the guide anti-drop sleeve Ⅰ4, the pulley seat Ⅰ2 and the pulley Ⅰ3 to rotate, so as to realize the deflection and guidance of the steel wire rope 14 in the horizontal plane. Specifically, the method for using the wire rope traction mechanism with adjustable traction position and direction in this embodiment includes the following steps: a. When towing a trailer moving upward along a slope, a wire rope traction mechanism is installed at the top of the slope, and a winch is located behind the wire rope traction mechanism. The wire rope of the winch passes through the top wheel groove of pulley I, the guide anti-drop sleeve I, the perforation, the bottom wheel groove of pulley II, and the guide anti-drop sleeve II in sequence and then extends toward the trailer 21. A traction hook 20 is provided at the front end of the wire rope, and is connected to the trailer through the traction hook. A hanging plate adapted to the traction hook is provided on the trailer. The action of the winch is used to provide pulling force to the trailer, so that the trailer moves along the slope; b. When the trailer needs to move horizontally, the driving mechanism pushes the sliding sleeve to move horizontally, and the pulley seat I and the pulley seat II rotate accordingly to adjust the pulling direction and position of the wire rope; c. When the trailer moves laterally but the driving mechanism does not move, the holes formed by the two pulleys III are used as fulcrums to limit the lateral movement of the wire rope, so that the direction of the wire rope between pulleys I and III remains unchanged, and the traction direction of the wire rope is changed by the rotation of the pulley seat II to increase the lateral traction range; d. When the traction distance changes, the traction frame swings up and down around the hinge point between it and the frame to adjust the angle between the wire rope and the ground.

[0031] This embodiment is hinged with the frame through the traction frame, which can swing up and down to adapt to different traction angles and traction forces; the vertical guide pulley block formed by the guide anti-drop sleeve I, the pulley seat I and the pulley I can rotate in the horizontal plane to realize the deflection and guidance of the wire rope in the horizontal plane; the transverse guide pulley block formed by the pulley II, the sliding sleeve, the pulley seat II, the pulley III and the guide anti-drop sleeve II can deflect in the wire rope traction plane to realize the deflection and guidance of the wire rope; the driving mechanism can push the transverse guide pulley block to move horizontally to realize the adjustment of the traction position and direction.
