Description

Technical Field

[0001] The invention relates to the field of lifting devices, and in particular to a protective garden engineering greening tree lifting device. Background Art

[0002] With the acceleration of urbanization, people have higher and higher requirements for the quality of living environment. Landscaping has become one of the important means to improve the quality of cities. However, in the process of garden renovation or urban construction, it is usually necessary to relocate existing trees to other places or transport them from nurseries to construction sites. Traditional tree transportation methods mostly use manpower with simple mechanical tools such as ropes and pulleys. This method is not only inefficient, but also easily causes damage to trees, affecting their survival rate.

[0003] After searching, the patent with authorization announcement number CN117963700B discloses a garden engineering greening tree lifting device, including a square tubular hanger, with ears for hanging slings fixed on the left and right ends of the hanger; a slide groove is opened along its length direction at the upper end of the hanger, and a left slider and a right slider are slidably arranged in the slide groove. The lifting device automatically adjusts the lifting position close to the center of gravity of the tree through multiple trial liftings, and then lifts the tree approximately horizontally. Although the device can eventually achieve quasi-horizontal lifting, it still has some shortcomings in practical applications. Specifically, it relies on repeated experiments to determine the correct lifting position, which greatly reduces work efficiency. Secondly, if the tree is not stopped and lowered in time during the trial lifting process, the boom may cause the trunk to tilt too much due to excessive sliding, thereby causing a safety hazard. In addition, the sliding distance between the lifting rope and the moving frame is very limited, and it cannot adapt to various situations or handle particularly heavy tree trunks. Therefore, its scope of application is limited. Summary of the invention

[0004] In order to overcome the shortcomings of the existing lifting device that the center of gravity of the tree is accurately found through multiple trial liftings and then the tree is lifted in a balanced manner, which is inefficient and multiple trial liftings may easily cause safety hazards, the present invention provides a protective garden engineering greening tree lifting device.

[0005] The technical solution is: a protective garden engineering greening tree lifting device, including a main frame, a sliding frame and a fixed pulley, the main frame is the load-bearing carrier of the device, the top of the main frame is fixedly connected with a docking shaft for docking an external lifter, the sliding frame is slidably installed in the slide groove inside the main frame, and the fixed pulley is rotatably installed in the sliding frame; it also includes: a cross frame, which is arranged at the lower part of the main frame, and the bottom of the two ends of the cross frame are provided with hooks, and the hooks are used to hook up the binding ropes and simultaneously lift the bound trees at both ends of the cross frame; sliding blocks, which are symmetrically slidably installed on the cross frame, and the tops of the sliding blocks are all equipped with rings; a steel wire sling is wound around the fixed pulley, and the two ends of the steel wire sling are respectively connected to the sliding block through the rings; a tensioning member is arranged at the The tensioning member is on the upper part of the main frame, and is used to adjust the sliding frame and tighten the wire sling. The tensioning member includes: a winding wheel, which is rotatably installed on the inner wall of the upper part of the main frame; a wire rope, which is wound on the winding wheel, and the end of the wire rope is connected to the top of the sliding frame; a servo motor I, which is installed on the outer wall of one side of the upper part of the main frame, and the output shaft of the servo motor I is connected to the rotating shaft of the winding wheel; a balance adjustment component is arranged on the transverse frame, and the balance adjustment component is used to balance the trees lifted at both ends of the transverse frame. When the trees at both ends are synchronously lifted on the transverse frame by the hooks, the force arms of the lifted trees at both ends are adjusted by the balance adjustment component, so that the trees at both ends are lifted in a balanced manner at both ends of the transverse frame, while increasing the number of lifted trees, the effect of efficiently lifting trees horizontally is achieved.

[0006] As a further preferred solution, universal joints are symmetrically arranged at the bottom of the horizontal frame, and the hooks are rotatably installed at the bottom of both ends of the horizontal frame through the universal joints. The flexible rotation of the universal joints can adapt to the angle of the hook when lifting the tree, thereby improving the anti-interference ability of the hook when lifting the tree.

[0007] As a further preferred scheme, the balance adjustment component includes: a center block, fixedly connected to the center position of the horizontal frame, and the center block is vertically aligned with the main frame directly above it; a level tube, symmetrically installed on the top of the center block, the level tube is a U-shaped tube, and the two tube openings at its upper end are small-diameter oil filling ports, and the interior of the level tube is used to store liquid oil; two groups of liquid level sensors, each group of liquid level sensors is symmetrically arranged in the tube walls at both ends of the level tube, each group of the liquid level sensors is provided with two and are close to each other, when the horizontal frame is horizontal, the liquid oil inside the level tube is immersed in the lower liquid level sensor; a screw rod, symmetrically rotatably installed inside the horizontal frame, and the screw rod is connected to the sliding block screw corresponding to the same side. The servo motor II is symmetrically installed on both sides of the center block, the output shaft of the servo motor II is connected to the corresponding screw rod on the same side, and the liquid level sensor is electrically connected to the servo motor II on the same side. When the trees at both ends are lifted by the cross frame hook and deviate due to weight, the deviation of the cross frame causes the level tube to deviate. After the oil level in the level tube submerges the liquid level sensor on that side for a preset time, the liquid level sensor sends an electrical signal to control the servo motor II to start through the controller, so that the servo motor II can drive the sliding block to slide toward the inner center block, and cooperate with the control tensioning member to synchronously tighten the wire sling, so that the force arm of the wire sling on the lower side to pull up the tree is reduced, so that the trees at both ends of the cross frame are gradually adjusted to a horizontal state.

A plurality of the hinge blocks are alternately hinged through the hinge shaft to form two symmetrical reinforcement plates, and the reinforcement plates are symmetrically supported between the main frame and the center block to avoid circular swinging around the center block when trees are lifted at both ends of the cross frame, thereby improving the stability of the device when lifting trees.

[0009] As a further preferred solution, it also includes a sensing component, which includes: a capacitive sliding sensor, which is symmetrically arranged on the front side surfaces of the left and right parts of the transverse frame, and the surface of the capacitive sliding sensor is evenly provided with sensing points; a sensing block, which is installed on the inner side wall of the sliding block, and the sensing block slides and fits on the corresponding capacitive sliding sensor, and the sensing block is used to trigger the sensing point of the capacitive sliding sensor; a sensing controller, which is installed on the upper part of the main frame near the servo motor I, and the sensing controller is electrically connected to the servo motor I, and the sensing controller is connected to the capacitive sliding sensor through an electrical signal. When the sliding block slides relatively on the transverse frame, when the sensing block in the sliding block on one side of the transverse frame continuously slides over the capacitive sliding sensor, the capacitive sliding sensor will send an electrical signal to control the sensing controller, so that the sensing controller can control the servo motor I to start, and control the servo motor I to rotate forward and reverse according to the sliding direction of the sliding block on the transverse frame, so that the winding wheel can adaptively reel in or unreel, and the wire sling can adaptively adjust the sliding of the sliding block to be in a tensioned state.

[0010] As a further preferred solution, clamping assemblies are symmetrically arranged on both sides of the lower part of the main frame, and the clamping assemblies include: a fixing frame, symmetrically fixed to both sides of the lower part of the main frame; a guide block, rotatably mounted on the fixing frame, a through opening is opened inside the guide block, and the wire sling symmetrically slides through the through opening of the guide block; a clamping block, symmetrically slidably mounted in the through opening of the guide block through a guide rod, and the clamping surface of the clamping block is provided with concave and convex patterns for increasing friction; a connecting plate, fixed to the connecting rod of the clamping block; a dual-axis motor, mounted in the guide block, The dual-axis motor is electrically connected to the capacitive sliding sensor on the opposite side; the threaded rod is symmetrically installed on the output shaft of the dual-axis motor, and the threaded rod and the connecting plate are threadedly connected. When the sliding block on one side moves the adjustment position of the horizontal frame, when the sensing block on this side triggers the capacitive sliding sensor, the capacitive sliding sensor will control the dual-axis motor on the other side to start through the built-in controller, so that the unchanged wire rope on the other side is clamped by the clamping block. When adjusting the balance of the horizontal frame, the unadjusted wire rope on the other side is kept in a locked state, thereby improving the safety and stability of the wire rope adjustment process.

[0012] As a further preferred embodiment, the contact belt is replaceably installed on the lifting sling. The contact belt can be replaced according to the actual size of the tree so that the contact belt can completely wrap the tree. Anti-slip curved patterns are provided on the side of the contact belt that bears the load of the tree.

[0013] The present invention has the following advantages: 1. A balance adjustment component is provided. When two trees are lifted at one time and their weights are inconsistent, the length of the lever arm is adjusted by driving the lead screw through a servo motor, and the relaxed wire sling is tightened in real time in cooperation with the tensioning member, so that the trees at both ends of the horizontal frame are automatically balanced, ensuring that the trees remain level during transportation, thereby improving the overall operation efficiency.

[0016] 4. The induction part cooperates with the self-locking mechanism of the clamping assembly to lock the wire sling on the side that does not need to be adjusted when adjusting one end of the wire sling, so that the wire sling cannot slide to the other side, reducing the wear and tear of components caused by frequent adjustments and enhancing the safety of the device when in use.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] Embodiment 1: A protective gardening tree lifting device, such as Figure 1-Figure 3As shown, it includes a main frame 1, a sliding frame 3 and a fixed pulley 4. The main frame 1 is a load-bearing carrier of the device. A docking shaft 2 for docking an external jack is fixedly connected to the top of the main frame 1. The sliding frame 3 is slidably installed in the slide groove inside the main frame 1, and the fixed pulley 4 is rotatably installed in the sliding frame 3; it also includes: a transverse frame 5, which is arranged at the lower part of the main frame 1, and hooks 501 are arranged at the bottom of both ends of the transverse frame 5. The hooks 501 are used to hook the binding rope and simultaneously lift the bound trees at both ends of the transverse frame 5; sliding blocks 6 are symmetrically slidably installed on the transverse frame 5, and rings are installed on the tops of the sliding blocks 6; a steel wire sling 7 is wound around the fixed pulley 4, and the two ends of the steel wire sling 7 are respectively connected to the sliding blocks 6 through rings; a tensioning member 8 is arranged on the upper part of the main frame 1, and the tensioning member 8 is used to adjust the sliding frame 3 and tighten the steel wire sling 7. The tensioning member 8 includes: a winding wheel 801, which is rotatably installed on the inner wall of the upper part of the main frame 1; a steel wire rope 802, which is wound on the winding wheel On 801, the end of the wire rope 802 is connected to the top of the sliding frame 3; the servo motor I 803 is installed on the outer wall of one side of the upper part of the main frame 1, and the output shaft of the servo motor I 803 is connected to the rotating shaft of the winding wheel 801; the balance adjustment component 9 is arranged on the horizontal frame 5, and the balance adjustment component 9 is used to balance the trees lifted at both ends of the horizontal frame 5. When the trees at both ends are synchronously lifted on the horizontal frame 5 by the hook 501, the force arm of the trees lifted at both ends is adjusted by the balance adjustment component 9, so that the trees at both ends are lifted in a balanced manner at both ends of the horizontal frame 5, while increasing the number of lifted trees, achieving the effect of efficient horizontal lifting of trees; the bottom of the horizontal frame 5 is symmetrically provided with universal joints 502, and the hooks 501 are rotatably installed at the bottom of both ends of the horizontal frame 5 through the universal joints 502. The universal joints 502 can be flexibly rotated to adapt to the angle of the hooks 501 when lifting trees, thereby improving the anti-interference performance of the hooks 501 when lifting trees.

[0030] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the balance adjustment component 9 includes: a center block 901, which is fixedly connected to the center position of the horizontal frame 5, and the center block 901 is vertically aligned with the main frame 1 directly above; a level tube 902, which is symmetrically installed on the top of the center block 901, and the level tube 902 is a U-shaped tube, and the two tube openings at the upper end thereof are small-diameter oil filling ports, and the inside of the level tube 902 is used to store liquid oil; two groups of liquid level sensors 903, each group of liquid level sensors 903 is symmetrically arranged in the tube wall at both ends of the level tube 902, and each group of liquid level sensors There are two level sensors 903 which are close to each other. When the horizontal frame 5 is horizontal, the liquid level of the liquid oil in the level tube 902 only immerses the lower level sensor 903, but does not immerse the upper level sensor 903. The upper and lower level sensors 903 in the same group can better monitor the slight deviation of the liquid level. The screw rod 904 is symmetrically rotatably installed inside the horizontal frame 5. The screw rod 904 is threadedly connected to the corresponding sliding block 6 on the same side. The servo motor II 905 is symmetrically installed on both sides of the center block 901. The output shaft of the servo motor II 905 is connected to the corresponding screw rod 904 on the same side, and the liquid level sensor 903 is electrically connected to the servo motor II 905 on the same side. When the liquid oil level is horizontal, it is located between the upper and lower liquid level sensors 903. When the trees at both ends are lifted by the hook 501 of the horizontal frame 5 and deviate due to their weight, the deviation of the horizontal frame 5 causes the level tube 902 to deviate. The oil level in the level tube 902, while originally submerging the lower liquid level sensor 903, continues to submerge the upper one on the lower side. A liquid level sensor 903. When the liquid level simultaneously submerges the upper and lower liquid level sensors 903 on the lower side and reaches a preset time, the upper liquid level sensor 903 sends an electrical signal to control the servo motor II 905 to start through the controller, so that the servo motor II 905 can drive the sliding block 6 to slide toward the inner center block 901, and cooperate with the control tensioning member 8 to synchronously tighten the wire sling 7, so that the force arm of the wire sling 7 on the lower side to pull up the tree is reduced, so that the trees at both ends of the cross frame 5 are gradually adjusted to a horizontal state.

[0031] like Figure 1 , Figure 6 and Figure 7 As shown, a stabilizing member 10 is provided between the main frame 1 and the balance adjustment component 9. The stabilizing member 10 includes a hinge block 101 and a hinge shaft 102. A plurality of hinge blocks 101 are alternately hinged through the hinge shaft 102 to form two symmetrical reinforcement plates. The reinforcement plates are symmetrically supported between the main frame 1 and the center block 901 to avoid circular swinging around the center block 901 when trees are lifted at both ends of the cross frame 5, thereby improving the stability of the device when lifting trees.

[0032] like Figure 1 and Fig.10As shown, a sling 13 is provided at the bottom of the hook 501, and the sling 13 includes: a lifting sling 131, which is symmetrically assembled under the corresponding hook 501 on the same side; a contact belt 132, which is slidably arranged on the inner side of the belt body of the lifting sling 131 that contacts the tree, and the contact belt 132 is used to prevent the lifting sling 131 from cross-cutting the lifted tree when it shakes, thereby improving the stability of the tree when it is lifted and transported; the contact belt 132 is replaceably installed on the lifting sling 131, and the contact belt 132 can be replaced and used according to the actual size of the tree, so that the contact belt 132 can completely wrap the tree, and the side of the contact belt 132 that bears the load of the tree is provided with anti-slip curved patterns.

[0033] When using the device to lift trees, first fix the main frame 1 on the external lifting device and ensure a stable connection through the docking shaft 2, then hang the lifting sling 131 on the corresponding hook 501, and then start lifting the trees. First, move the two trees to be lifted between the two lifting slings 131 respectively. The trees will pass through the lifting slings 131 and be supported by the contact belt 132 to prevent the lifting sling 131 from directly contacting the trees and cutting and damaging the bark of the lifted trees. The design of the universal joint 502 allows the hook 501 to be flexibly adjusted according to the angle of the tree to meet different lifting requirements. When the tree is stably mounted, the operator first uses the lifting device to lift the trees mounted at both ends upwards. If the weights of the two trees are different, the horizontal frame 5 will tilt. At this time, the tilt of the horizontal frame 5 will drive the level tube 902 to tilt. The liquid oil in the level tube 902 will shift with the tilt of the horizontal frame 5, and a group of liquid level sensors 903 that are tilted and shifted downward will be immersed in the liquid oil in the level tube 902. When the upper and lower liquid level sensors 903 of the group are immersed in the liquid oil for a preset period of time, the upper liquid level sensor 903 will send an electrical signal to its internal integrated controller, which will then activate the servo motor II 905 on the same side. The output shaft of the servo motor II 905 drives the corresponding screw rod 904 to rotate, and the threaded drive of the screw rod 904 causes the sliding block 6 to move toward the center block 9 on the horizontal frame 5. 01 direction, in this process, by starting the servo motor I 803, the output shaft of the servo motor I 803 drives the winding wheel 801 to rotate, and the rotating winding wheel 801 will tighten the wire rope 802, so that the wire rope 802 pulls the sliding frame 3 upward, so that the sliding frame 3 moves upward in the main frame 1. At this time, the fixed pulley 4 on the sliding frame 3 continuously tightens the wire sling 7, so that when the sliding block 6 moves toward the direction of the center block 901, the relaxed wire sling 7 will be continuously tightened, thereby shortening the force arm on one side that is deviated downward due to the heavier weight, until the forces at both ends of the horizontal frame 5 tend to be balanced and the horizontal state is restored. At the same time, the level tube 902 will also follow the horizontal frame 5 to restore the horizontal state again, and the liquid oil inside the level tube 902 will no longer immerse the deviated side. At the same time, the liquid level sensor 903 on the upper side stops and no longer activates the servo motor II 905 on the same side, so that the sliding block 6 on the horizontal frame 5 stops, and at the same time, the servo motor I803 is turned off to stop the sliding frame 3 in the main frame 1, and the wire sling 7 is maintained in a tensioned state, so that the entire device is in a state of horizontally lifting trees, and finally the trees lifted by the crane are transported to the target location. In this process, the hinge block 101 and the hinge shaft 102 cooperate with each other to form a stabilizing member 10, and the stabilizing member 10 is limited on the central block 901, so as to further stabilize the horizontal frame 5 and the entire lifting device, avoid circumferential rotation of the horizontally lifted trees, and improve the stability and safety of the lifting device when lifting trees.

[0034] Embodiment 2: Based on embodiment 1, Figure 1 , Figure 6 , Figure 7 and Figure 8 As shown, the induction member 11 is also included, and the induction member 11 includes: a capacitive sliding sensor 111, which is symmetrically arranged on the front side surfaces of the left and right parts of the horizontal frame 5, and the surface of the capacitive sliding sensor 111 is evenly provided with sensing points; a sensing block 112, which is installed on the inner wall of the sliding block 6, and the sensing block 112 slides and fits on the corresponding capacitive sliding sensor 111, and the sensing block 112 is used to trigger the sensing point of the capacitive sliding sensor 111; a sensing controller 113, which is installed on the upper part of the main frame 1 near the servo motor I803, and the sensing controller 113 is electrically connected to the servo motor I803, and the sensing control The sensor 113 is connected to the capacitive sliding sensor 111 through an electrical signal. When the sliding block 6 slides relatively on the horizontal frame 5, the sensing block 112 in the sliding block 6 on one side of the horizontal frame 5 continuously slides over the capacitive sliding sensor 111. The capacitive sliding sensor 111 will send an electrical signal to control the sensing controller 113, so that the sensing controller 113 can control the servo motor I803 to start, and control the servo motor I803 to rotate forward and reverse according to the sliding direction of the sliding block 6 on the horizontal frame 5, so that the winding wheel 801 can adaptively take up or release the wire, so that the wire sling 7 can adapt to the sliding of the sliding block 6 and be in a taut state.

[0035] like Figure 1 , Figure 6 and Fig. 9 As shown, the clamping components 12 are symmetrically arranged on both sides of the lower part of the main frame 1, and the clamping components 12 include: a fixing frame 121, which is symmetrically fixed to both sides of the lower part of the main frame 1; a guide block 122, which is rotatably mounted on the fixing frame 121, and a through hole is opened inside the guide block 122, and the wire sling 7 symmetrically slides through the through hole of the guide block 122; a clamping block 123, which is symmetrically slidably mounted in the through hole of the guide block 122 through a guide rod, and the clamping surface of the clamping block 123 is provided with concave and convex patterns to increase friction; a connecting plate 124, which is fixed to the connecting rod of the clamping block 123; a double-axis motor 125, which is installed in the guide block 122, and the double-axis motor 125 is connected to the opposite side. The capacitive sliding sensor 111 is electrically connected; the threaded rod 126 is symmetrically installed on the output shaft of the dual-axis motor 125, and the threaded rod 126 and the connecting plate 124 are threadedly connected. When the sliding block 6 on one side moves the adjustment position of the horizontal frame 5, when the sensing block 112 on this side triggers the capacitive sliding sensor 111, the capacitive sliding sensor 111 will control the dual-axis motor 125 on the other side to start through the built-in controller, so that the unchanged wire rope 7 on the other side is clamped by the clamping block 123. When adjusting the balance of the horizontal frame 5, the unadjusted wire rope 7 on the other side is kept in a locked state, thereby improving the safety and stability of the adjustment process of the wire rope 7.

[0036] Since the capacitive sliding sensor 111 on the horizontal frame 5 monitors the movement state of the sliding block 6 in real time, when the sliding block 6 slides on the horizontal frame 5, the inductive block 112 inside it will trigger the sensing point of the capacitive sliding sensor 111, and the capacitive sliding sensor 111 will generate an electrical signal and send it to the inductive controller 113. After receiving the signal, the inductive controller 113 directly controls the servo motor I803 to rotate. When the sliding block 6 slides inward toward the center block 901 and relaxes the wire sling 7, the inductive controller 113 controls the servo motor I803 to drive the winding wheel 801 to rotate forward. The forward rotating winding wheel 801 will pull up the sliding frame 3 and the fixed pulley 4, so that the fixed pulley 4 will pull the relaxed wire sling 7 upward. At the same time, the capacitive sliding sensor 111 will also control the servo motor I803 through its internal integrated control The device controls the double-axis motor 125 on the other side, so that the bidirectional output shaft of the double-axis motor 125 synchronously drives the threaded rod 126 to rotate, and the rotating threaded rod 126 drives the threaded connecting plate 124 to slide in the direction of the wire rope 7 until it drives the clamping block 123 to stably clamp the wire rope 7, so that the wire rope 7 on this side is in a locked state, thereby making the horizontal frame 5 on the unadjusted side in a stable state. Similarly, when the sliding block 6 slides outward away from the center block 901 and tightens the wire rope 7, the induction controller 113 drives the winding wheel 801 to reverse by controlling the servo motor I803. The reversed winding wheel 801 will release the tightened wire rope 7 downward by lowering the sliding frame 3 and the fixed pulley 4, thereby making the wire rope 7 always in a tightened state, thereby improving the convenience of use of the present lifting device.
