Description

Technical Field

[0001] The invention relates to the technical field of winches, in particular to a building winch based on a novel transmission structure. Background Art

[0002] A winch is a light and small lifting equipment that uses a drum to wrap a wire rope or chain to lift or pull heavy objects. It is also called a winch. The winch can lift vertically and pull heavy objects horizontally or at an angle. The winch is divided into three types: manual winch, electric winch and hydraulic winch. The electric winch is the main one and can be used alone or as a component of machinery such as lifting, road construction and mine hoisting. It is widely used due to its simple operation, large rope winding capacity and easy relocation. It is mainly used for lifting or towing materials in construction, water conservancy projects, forestry, mines, docks, etc.

[0003] When the existing winch is winding the wire rope, the wire rope will be piled up and wound together, causing the wire ropes to be squeezed against each other, which may easily cause wire clamping and affect the release of the wire rope. At the same time, the winding drum of the existing winch is exposed to the outside, which may easily cause accidents during the winding of the wire rope.

[0004] After searching, it was found that the publication number is CN112374409B, which discloses a winch for lifting materials for construction sites, relates to the technical field of winches, specifically a winch for lifting materials for construction sites, comprising a base, a drive motor is fixedly installed on the top of the base, a gear plate is fixedly installed on the output shaft of the drive motor, a fixed block is arranged on the left side of the gear plate, a locking piece is hinged on the top of the fixed block, a steel wire rope is fixedly connected to the right side of the locking piece, and an electric telescopic rod is fixedly connected to the bottom of the right end of the steel wire rope.

[0005] The driving motor, winding drum and reduction box in the above application each occupy space, making the overall volume of the winch relatively large and inconvenient to use in a narrow space. Summary of the invention

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: a construction winch based on a new transmission structure, comprises a base, wherein the left and right sides of the upper surface of the base are respectively fixedly connected with a support base, and the front and rear sides of the upper surface of the base are respectively fixedly connected with a guard plate, and a winding wheel is provided through the opposite side of the two support bases, and the upper side walls of the two support bases are rotatably connected with a reciprocating screw, one end of the reciprocating screw is connected to the shaft end of the winding wheel through a belt, and the surface of the reciprocating screw is threadedly connected with a guide seat, and a guide opening is opened on the side wall of the guard plate, and the opposite side of the two guard plates is fixedly connected with a top plate, the upper surface of the guide seat is slidably connected to the lower surface of the top plate, and the upper surface of the top plate is fixedly connected with a driver, and the driving end of the driver is connected to the shaft end of the winding wheel through a reducer. An adjustment component is arranged above the guide seat, and the adjustment component is used to adjust the tension of the wire rope on the surface of the winding wheel.

[0008] Preferably, a guide hole is opened on the surface of the guide seat, the inner wall of the guide hole and the inner wall of the guide opening are rotatably connected to two vertical guide rollers respectively, and the inner wall of the guide opening is rotatably connected to two horizontal guide rollers.

[0009] Preferably, the adjustment assembly includes an electric push rod, the bottom end of which is fixedly connected to the upper surface of the top plate, the driving end of which is fixedly connected to a U-shaped connecting frame, the bottom end of which is fixedly connected to a spring telescopic rod, and the bottom end of which is fixedly connected to a pressure plate.

[0010] Preferably, the adjustment assembly further comprises a slot, and the slot is formed on the upper surface of the guide seat.

[0011] Preferably, a mounting seat is fixedly connected to the inner side wall of the connecting frame, a telescopic rod is fixedly connected to the bottom of the mounting seat, and a spring is built into the telescopic rod.

[0012] Preferably, the adjustment assembly further comprises a limiting ring, the inner wall of the limiting ring is fixedly connected to the outer wall of the driving end of the driver, and the surface of the limiting ring is provided with a plurality of locking openings distributed in a ring shape.

[0013] Preferably, a bearing seat is fixedly connected to the surface of the support seat, a bearing body is fixedly connected to the interior of the bearing seat, the shaft of the winding wheel is interference fit with the bearing body, an oil filling hole is commonly provided on the upper surfaces of the bearing seat and the bearing body, a lubrication assembly is arranged above the bearing seat, the lubrication assembly includes an adding cylinder and two raised layers, and the outer walls of the two raised layers are fixedly connected to the lower side wall of the guide seat.

[0014] Preferably, a magnetic block 1 is fixedly connected to the lower surface of the raised layer, a partition is fixedly connected to the upper inner wall of the adding cylinder, the bottom of the adding cylinder protrudes downward to form an adding cavity, and an adding tube is fixedly connected to the bottom of the adding cavity.

[0015] Preferably, the top of the partition is fixedly connected with an adding end, and the adding end is covered with a sealing cover.

[0016] Preferably, a T-shaped connecting rod is provided through the surface of the partition, the top end of the connecting rod is fixedly connected to a second magnetic block, the second magnetic block and the first magnetic block magnetically repel each other, a spring part is sleeved on the surface of the connecting rod, and the bottom end of the connecting rod is fixedly connected to an I-shaped sealing part.

[0017] Working principle: When in use, one end of the wire rope is wound and fixed on the winding wheel, and the other end passes through the guide hole and the guide port in turn. The operating driver drives the reducer to operate, and the reducer drives the winding wheel to rotate, so that the winding wheel reels the wire rope, and when the winding wheel rotates, the reciprocating screw is driven by the belt to rotate, and the rotation of the reciprocating screw drives the guide seat to slide back and forth to guide the wire rope, so that it is evenly wound on the outside of the winding wheel to avoid the problem of overlapping and winding of the wire ropes and clamping the wire rope. When the wire rope moves, the friction between the wire rope and the guide seat and the guide port can be reduced through the vertical guide roller and the horizontal guide roller, so as to avoid severe wear of the wire rope, which is beneficial to increase the service life of the wire rope.

[0018] The device protects the winding wheel through the cooperation of the base, the support seat, the protective plate and the top plate to prevent the winding wheel from being touched by personnel when winding the wire rope, thereby avoiding harm to personnel. The vertical transmission arrangement of the drive, the reducer and the winding wheel is conducive to reducing the footprint of the device. Compared with the existing technology, it is convenient to use in a narrow space.

[0019] When the winding wheel is in no-load winding, the electric push rod is operated, and the electric push rod is retracted a short distance, so that the driving end of the electric push rod drives the connecting frame to descend, and the connecting frame drives the spring telescopic rod to descend, so that the pressure plate passes through the slot and presses down on the wire rope in the guide seat, thereby applying a certain compression force to the wire rope to prevent the wire rope from loosening on the winding wheel. When the winding wheel is normally winding and releasing the wire, the wire rope is kept taut by the pulling force of the heavy object. At this time, the electric push rod is retracted to separate the pressure plate from the wire rope, thereby avoiding applying pressure to the wire rope. The wire rope runs more smoothly. When the winch is not in use, the electric push rod is retracted a long distance, so that the connecting frame drives the telescopic rod to retract and press against the limit ring. When the driver starts by mistake and drives the limit ring, the telescopic rod will be inserted and rotated into the locking mouth below it to prevent the driver from rotating by mistake, avoiding danger caused by the driver's misstart, protecting the safety of personnel, and at this time, the connecting frame drops a long distance to keep the spring telescopic rod at the minimum retraction range, so that the pressure plate completely presses the wire rope to prevent the wire rope from loosening when loading and unloading goods during the winch shutdown period.

[0020] Liquid lubricating oil is added to the interior of the adding cylinder. When the winch is running, the guide seat drives the raised layer to reciprocate. When the raised layer moves to the top of the adding cylinder, the magnetic repulsion between magnetic block 1 and magnetic block 2 pushes the connecting rod down, and the connecting rod drives the seal to move down, thereby opening the adding chamber, allowing the lubricating oil to drip from the adding tube into the oil filling hole, thereby realizing automatic lubrication of the bearing body, saving manpower, and extending the service life of the winch.

[0021] The present invention provides a construction winch based on a novel transmission structure, which has the following beneficial effects: 1. The present invention provides all-round shielding and protection for the winding wheel through the cooperation of the base, the support seat, the protective plate and the top plate to prevent the winding wheel from being touched by personnel when winding the wire rope and causing harm to personnel. The driver, the reducer and the winding wheel are distributed in the vertical direction, which is beneficial to reducing the footprint of the device. Compared with the prior art, it is convenient to use in a narrow space.

[0022] 2. When the winding wheel of the present invention rotates, the reciprocating screw is driven to rotate, and the rotation of the reciprocating screw drives the guide seat to slide back and forth to guide the wire rope, so that it is evenly wound around the outside of the winding wheel, avoiding the overlapping and entanglement of the wire ropes, and the friction between the wire rope and the guide seat and the guide port can be reduced by the vertical guide roller and the horizontal guide roller, avoiding serious wear of the wire rope, and limiting the shaking amplitude of the wire rope by the guide port, avoiding that when the wire rope moves driven by the guide seat, the line segment area connected to the heavy object will not produce large shaking, affecting the stability of lifting or towing the heavy object.

[0023] 3. The present invention can adjust the height of the pressure plate and the telescopic rod through the electric push rod. When the winding wheel is unloaded, the pressure plate elastically presses the steel wire to apply a certain pressing force to the steel wire rope to prevent the steel wire rope from loosening on the winding wheel. When the winch stops, the telescopic rod is contracted to press against the limit ring. When the driver starts by mistake, the telescopic rod will be inserted and rotated into the locking port below it, activating the automatic and rapid braking effect, avoiding danger caused by the accidental start of the driver and protecting the safety of personnel.

[0024] 4. When the guide seat of the present invention drives the raised layer to move to the top of the adding cylinder, the magnetic repulsion between the first and second magnetic blocks pushes the connecting rod down to open the adding chamber, so that the lubricating oil drips from the adding tube into the oil filling hole, thereby realizing automatic lubrication of the bearing body, saving manpower and extending the service life of the winch.

[0028] Example: Please see attached Figure 1 -Attached Figure 3 The embodiment of the present invention provides a construction winch based on a new transmission structure, including a base 1, the left and right sides of the upper surface of the base 1 are respectively fixedly connected with a support seat 2, the left and right sides of the upper surface of the base 1 are respectively fixedly connected with the support seat 2, the front and rear sides of the upper surface of the base 1 are respectively fixedly connected with a protective plate 3, a winding wheel 4 is penetrated through the opposite side of the two support seats 2, and a reciprocating screw 5 is connected to the upper side walls of the two support seats 2 for common rotation, one end of the reciprocating screw 5 is connected to the shaft end of the winding wheel 4 through a belt, and a guide seat 6 is threadedly connected to the surface of the reciprocating screw 5, and one of the protective plates A guide opening 9 is provided on the side wall of the guide seat 3, and the guide opening 9 is maintained at the center of the moving position of the guide seat 6. A top plate 11 is fixedly connected to the opposite side of the two protective plates 3. The upper surface of the guide seat 6 is slidably connected to the lower surface of the top plate 11. A driver 12 is fixedly connected to the upper surface of the top plate 11. The driving end of the driver 12 is connected to the shaft end of the winding wheel 4 through a reducer 13. An adjustment component 7 is arranged above the guide seat 6. The adjustment component 7 is used to adjust the tension of the steel wire rope on the surface of the winding wheel 4. A guide hole 14 is provided on the surface of the guide seat 6. The inner wall of the guide hole 14 and the inner wall of the guide opening 9 Two vertical guide rollers 15 are rotatably connected to each other, and the inner wall of the guide opening 9 is rotatably connected to two horizontal guide rollers 16. An inspection port is provided on the surface of another protective plate 3. The side wall of the inspection port is rotatably connected to an inspection door through an axis. The inspection door is locked with the protective plate 3 through a latch. By opening the inspection door, it is convenient to add lubricating oil and inspect the winding wheel 4. The winding wheel 4 includes two annular baffles. The opposite sides of the two annular baffles are fixedly connected to a shaft body. The shaft body is used for winding the wire rope. The outer side of the annular baffle is fixedly connected to a wheel axle. The outer wall of the reducer 13 is fixed to the adjacent support seat 2. The drive end of the driver 12 is fixedly connected to the input shaft of the reducer 13, the shaft end of the winding wheel 4 is fixedly connected to the output shaft of the reducer 13, the shaft end of the winding wheel 4 and one end of the reciprocating screw 5 are respectively fixedly connected with pulleys, and belts are provided on the two pulleys to realize the connection through belt transmission. The spacing between the two horizontal guide rollers 16 is consistent with the diameter of the wire rope, and the spacing between the two vertical guide rollers 15 is consistent with the diameter of the wire rope. The driver 12 circuit is connected to a controller, and the controller is connected to the electric push rod 71 circuit. The controller is used to control the driver 12 and the electric push rod 71.

[0029] Specifically, the horizontal center line of the guide seat 6 in the initial position is maintained in the same vertical plane as the winding center point of the wire rope and the winding wheel 4, and the length of the thread groove of the reciprocating screw 5 is the sum of the length of the shaft of the winding wheel 4 and the guide seat 6, so that when the guide seat 6 moves to the edge of the reciprocating screw 5, the center point of the guide seat 6 and the edge of the winding wheel 4 are maintained in the same vertical plane, and the driver 12 is used to drive the reducer 13 to operate, and the operation of the reducer 13 drives the winding wheel 4 to rotate and rewind the wire rope, and the rotation of the winding wheel 4 drives the reciprocating screw 5 to rotate, and the rotation of the reciprocating screw 5 drives the guide seat 6 to slide back and forth along the direction of the reciprocating screw 5, and the wire rope passes through the guide hole 14 and the guide port 9, so as to adjust the winding point of the wire rope and the winding wheel 4 when the guide seat 6 moves. The wire rope can be evenly wound on the surface of the winding wheel 4. The vertical guide roller 15 and the horizontal guide roller 16 are used to reduce the friction with the wire rope, and the guide port 9 is used to limit the swing amplitude of the wire rope to prevent the wire rope from moving under the drive of the guide seat 6. The line segment area connected to the heavy object will not produce a large swing, which will affect the stability of lifting or towing the heavy object. The top plate 11 is used to install the driver 12. The base 1, the support seat 2, the protective plate 3 and the top plate 11 are used to form a protection on the outside of the winding wheel 4 to prevent people from accidentally contacting the winding wheel 4 and causing damage. By stacking the driver 12, the reducer 13 and the winding wheel 4 and transmitting in the vertical direction, the floor space of the winch can be saved, making it suitable for use in narrow spaces.

[0030] Please see attached Figure 3 -Attached Figure 4 The adjusting assembly 7 includes an electric push rod 71, the bottom end of the electric push rod 71 is fixedly connected to the upper surface of the top plate 11, the driving end of the electric push rod 71 is fixedly connected to a U-shaped connecting frame 72, the bottom end of the connecting frame 72 is fixedly connected to a spring telescopic rod 73, the bottom end of the spring telescopic rod 73 is fixedly connected to a pressing plate 74, the adjusting assembly 7 also includes a slot 75, the slot 75 is opened on the upper surface of the guide seat 6, specifically, the contraction distance of the electric push rod 71 is two sections, the first contraction distance is kept at the pressing plate 74 elastically compressing the wire rope, the second contraction distance is longer than the first contraction distance, so that the telescopic rod 77 contracts and resists the limit ring 78, the two ends of the connecting frame 72 respectively pass through the top plate 11, and the connecting frame 72 is limited by the top plate 11.

[0031] Specifically, the slot 75 is used for the pressure plate 74 to pass through, the electric push rod 71 is used to adjust the height of the connecting frame 72, the spring telescopic rod 73 is used to connect the pressure plate 74 and the connecting frame 72, and when the pressure plate 74 descends to resist the wire rope, the spring telescopic rod 73 contracts to apply elastic pressure to the wire rope, so that the wire rope still maintains a certain tension when it is unloaded to avoid loosening.

[0032] Please see attached Figure 5The inner wall of the connecting frame 72 is fixedly connected with a mounting seat 76, and the bottom of the mounting seat 76 is fixedly connected with a telescopic rod 77, and the telescopic rod 77 has a built-in spring. The adjustment component 7 also includes a limit ring 78, and the inner wall of the limit ring 78 is fixedly connected to the outer wall of the driving end of the driver 12, and the surface of the limit ring 78 is provided with a plurality of locking openings 79 distributed in a ring shape.

[0033] Specifically, the distance between the bottom end of the telescopic rod 77 and the limit ring 78 is greater than the distance between the pressure plate 74 and the wire rope. The mounting seat 76 is used to fix the telescopic rod 77. The built-in spring of the telescopic rod 77 allows the telescopic rod 77 to unfold. When the winch is stopped, the operating electric push rod 71 contracts so that the telescopic rod 77 contracts and presses against the limit ring 78. When the winch is started by mistake, the winch drives the limit ring 78 to rotate, so that the locking port 79 on the limit ring 78 will rotate to the limit of the telescopic rod 77. The telescopic rod 77 is automatically inserted into the locking port 79 below it by the tension of the spring, thereby locking the limit ring 78 to avoid the occurrence of dangerous situations caused by the accidental opening of the winch.

[0034] Please see attached Figure 6 A bearing seat 18 is fixedly connected to the surface of the support seat 2, and a bearing body is fixedly connected to the inside of the bearing seat 18. The shaft of the winding wheel 4 is interference fit with the bearing body. An oil filling hole is provided on the upper surface of the bearing seat 18 and the bearing body. A lubrication component 8 is provided above the bearing seat 18. The lubrication component 8 includes an adding cylinder 81 and two raised layers 82. The outer walls of the two raised layers 82 are fixedly connected to the lower side wall of the guide seat 6. The adding cylinder 81 is made of magnetic isolation material. An inspection port is provided on the side wall of the adding cylinder 81. A transparent inspection window is fixedly connected to the inside of the inspection port. The transparent inspection window is used to facilitate personnel to observe the amount of lubricating oil on the inner wall of the adding cylinder 81.

[0035] Specifically, when the winch is in use, the bearings at both ends of the winding wheel 4 need to be lubricated regularly to reduce friction resistance, prevent sintering and wear, and reduce power consumption. The bearing body is used to rotatably support the winding wheel 4, and the oil filling hole is used to add lubricating oil to the inside of the bearing body. The lubrication assembly 8 is used to automatically add lubricating oil to the bearing body, thereby eliminating the need for frequent manual addition.

[0036] Please see attached Figure 7 -Attached Figure 8 The lower surface of the raised layer 82 is fixedly connected with a magnetic block 83, the upper inner wall of the adding cylinder 81 is fixedly connected with a partition 84, the bottom of the adding cylinder 81 protrudes downward to form an adding cavity 85, the bottom of the adding cavity 85 is fixedly connected with an adding tube 21, and the bottom end of the adding tube 21 is inserted into the oil filling hole.

[0037] Specifically, when the lubricating oil in the adding cylinder 81 flows into the adding chamber 85, it enters the oil filling hole through the adding pipe 21, thereby adding the lubricating oil to the inside of the bearing body.

[0038] Please see attached Figure 8 The top of the partition 84 is fixedly connected with the adding end 19, and the adding end 19 is covered with a sealing cover 20, and the sealing cover 20 can also be connected to the adding end 19 by a threaded connection.

[0039] Specifically, the adding end 19 is used to add lubricating oil into the adding cylinder 81, and the sealing cover 20 is used to seal the adding end 19 to reduce the loss of lubricating oil.

[0040] Please see attached Figure 8 A T-shaped connecting rod 87 is provided on the surface of the partition 84, and a second magnetic block 88 is fixedly connected to the top of the connecting rod 87. The second magnetic block 88 and the first magnetic block 83 magnetically repel each other. A spring member 86 is sleeved on the surface of the connecting rod 87, and an I-shaped sealing member 89 is fixedly connected to the bottom end of the connecting rod 87.

[0041] Specifically, the adding chamber 85 is composed of an upper temporary storage chamber, a middle sealing chamber and a lower conical chamber. The diameter of the sealing chamber is larger than the diameter of the temporary storage chamber. The sealing member 89 is composed of a rod and an upper piston plate and a lower piston plate fixed on the outside of the rod. The diameter of the lower piston plate is smaller than the diameter of the sealing chamber and larger than the diameter of the temporary storage chamber. The diameter of the upper piston plate is larger than the diameter of the temporary storage chamber. When the guide seat 6 reciprocates and drives the raised layer 82 to move above the adding cylinder 81, the magnetic repulsion of the magnetic block 1 83 and the magnetic block 2 88 pushes the connecting rod 87 to slide downward, and the connecting rod 87 drives the sealing member 89 to move downward. At this time, the lower piston plate descends to open the temporary storage chamber, so that the lubricating oil in the temporary storage chamber flows into the conical chamber. The lubricating oil is then added to the bearing body along the adding tube 21, and the upper piston will then descend and tightly press against the inner bottom wall of the adding cylinder 81 to block the lubricating oil from flowing into the temporary storage chamber, so that when the guide seat 6 drives the raised layer 82 to move above the adding cylinder 81, it stops moving, which causes the continuous addition of lubricating oil to cause waste. After the raised layer 82 is offset from the adding cylinder 81, the lower piston plate presses against the inner top wall of the sealing chamber through the elastic force of the spring member 86 to block the downstream flow of the lubricating oil, so that when the winch is running, the lubricating oil can be evenly and regularly injected into the oil filling hole in a quantitative manner to ensure that the bearing bodies at both ends of the winding wheel 4 can be automatically lubricated, thereby extending the service life of the winch.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
