Description

Technical Field

[0001] This invention relates to the field of lifting equipment, specifically to an integrated design device combining a double-girder bridge crane and a high-efficiency hoist. Background Technology

[0002] Double girder bridge cranes are a common type of crane, mainly used in heavy-duty applications. They consist of two bridges, two end cars, and a crane hoist assembly. This type of crane is characterized by its complex components, resulting in a relatively high cost. Double girder bridge cranes are mainly used in factories, warehouses, and material yards for lifting and transporting goods. High-efficiency hoist hoists are a type of lifting equipment with various types and functions, suitable for different industrial needs.

[0003] However, most traditional double-girder bridge cranes and high-efficiency hoist lifting machines are designed as a single unit with a relatively simple structure and poor protection for the lifting cables. This results in a higher probability of damage to the lifting cables, requiring replacement after a period of use, thus shortening the lifespan of the equipment.

[0004] Therefore, those skilled in the art have provided an integrated design device for a double-girder bridge crane and a high-efficiency hoist to solve the problems mentioned in the background art. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides an integrated design device for a double-girder bridge crane and a high-efficiency hoist, which solves the problem of relatively simple structure and poor protection effect on steel cables.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] The integrated design device of double-girder bridge crane and high-efficiency hoist lifting machine includes a main structure, a control and power supply mechanism, a lifting mechanism, a protection mechanism, a lubrication mechanism and a drive mechanism. The main structure includes a double-girder bridge body, and mounting bases are fixedly connected to the front and rear ends of the lower surface of the double-girder bridge body.

[0010] The control power supply mechanism includes a power distribution control cabinet, a placement rack and a spring connecting line. A first fixing block is fixedly connected to the front end of the upper surface of the placement rack. A limit groove is opened in the middle of the upper surface of the placement rack. A plurality of second fixing blocks are slidably connected to the front end of the inner wall of the limit groove, and a third fixing block is slidably connected to the rear end of the inner wall of the limit groove.

[0011] The lifting mechanism includes a placement seat, on which a first support block and a second support block are fixedly connected to the two sides of the middle of the upper surface of the placement seat, respectively. A shell is fixedly connected to the upper end of the outer wall of one side of the first support block, and a fixed shaft is rotatably connected to the middle of the upper end of the outer wall of one side of the first support block. A collecting roller is fixedly connected to the middle of the outer wall of the fixed shaft, and a steel cable is fixedly connected to the outer wall of the collecting roller.

[0012] The protective mechanism includes a first positioning block, a first sprocket, a second positioning block, and a second slide rod. A reciprocating screw is rotatably connected to the outer wall of one side of the first positioning block. A chain is sleeved on the outer wall of the first sprocket. A second sprocket is fixedly connected to the outer wall of one side of the reciprocating screw. An auxiliary ring is provided on one side of the outer wall of the reciprocating screw. A screw nut is fixedly connected to the upper end of the outer wall of the auxiliary ring. A through groove is opened at the lower part of the front end of the outer wall of the auxiliary ring. A first auxiliary pulley is rotatably connected to both the upper and lower ends of the inner wall of the through groove. A protective shell is fixedly connected to the outer wall of the first positioning block near the second sprocket. A second slider is slidably connected to the outer wall of the second slide rod. A second auxiliary pulley is rotatably connected to the lower end of the inner wall of the second slider.

[0013] The lubrication mechanism includes a reservoir, an interface fixedly connected to the middle of the upper surface of the reservoir, a second oil pump fixedly connected to the outer wall of the front end of the reservoir, a second oil pipe fixedly connected to the output end of the second oil pump, a plurality of positioning rods fixedly connected to the outer wall of the second oil pipe, and a second oil outlet connector fixedly connected to both ends of the second oil pipe away from the second oil pump. A first oil pump is fixedly connected to the outer wall of the rear end of the reservoir, a first oil pipe fixedly connected to the output end of the first oil pump, and a first oil outlet connector fixedly connected to the end of the first oil pipe away from the first oil pump.

[0014] The driving mechanism includes a bidirectional servo motor, a placement slot, a slide rail, and a placement bar. The output ends of the bidirectional servo motor are all fixedly connected to a rotating shaft. An auxiliary retaining ring is rotatably connected to one side of the outer wall of the rotating shaft. A drive gear is fixedly connected to the outer wall of the rotating shaft away from the bidirectional servo motor. Multiple movable pulleys are rotatably connected to the inner wall of the placement slot. Multiple teeth are fixedly connected to the upper surface of the placement bar.

[0015] Compared to traditional integrated designs of most double-girder bridge cranes and high-efficiency hoist lifting machines, this integrated design features a protective mechanism. The auxiliary ring within this mechanism reciprocates under the action of a reciprocating screw, and the screw and the take-up roller rotate synchronously under the action of the sprocket and chain. This allows the steel cable to be wound more precisely and neatly from one end to the other on the take-up roller, followed by a second layer of winding. This ensures the cable is neatly wound on the take-up roller under the action of the first auxiliary pulley, reducing damage caused by misalignment and minimizing damage during lifting heavy objects. Furthermore, the second auxiliary pulley, acting on the second slider, adjusts the angle of the cable according to the hook position, further reducing damage caused by cable deformation. Therefore, the lifespan and safety of this integrated design are both improved.

[0016] Furthermore, the control power supply mechanism is fixedly connected to the main body, the lifting mechanism is slidably connected to the main body, and the protection mechanism, lubrication mechanism, and drive mechanism are all fixedly connected to the lifting mechanism.

[0017] Furthermore, the power distribution control cabinet is fixedly connected to one side of the front end of the upper surface of the double beam bridge body, the placement frame is fixedly connected to the outer wall of the double beam bridge body away from the pedal, the first positioning block is fixedly connected to the upper surface of the second support block, the first sprocket is fixedly connected to the outer wall of the front end of the fixed shaft, the second positioning block is fixedly connected to the outer wall of the outer shell, the second slide rod is fixedly connected to the lower surface of the placement seat, the liquid storage tank is fixedly connected to the side of the upper surface of the placement seat away from the drive servo motor, and the bidirectional servo motor is fixedly connected to the outer wall of the rear end of the placement seat;

[0018] The above technical solutions enable the main body, control and power supply, lifting, protection, lubrication and drive mechanisms to be connected and used in coordination.

[0019] Furthermore, both ends of the spring connecting wire are fixedly connected to a line connector, and the lower surfaces of the first fixing block, the second fixing block and the third fixing block are all engaged with the line connector.

[0020] The above technical solution enables the first fixing block, the second fixing block, and the third fixing block to be connected by a spring connecting wire.

[0021] Furthermore, a tread is fixedly connected to the outer wall of one side of the double-beam bridge body, and a guardrail is fixedly connected to the upper surface of the tread away from the double-beam bridge body.

[0022] The above technical solution enables users to inspect the various components installed on the double-beam bridge via the pedal.

[0023] Furthermore, multiple rollers are rotatably connected to the outer walls on both sides of the second and third fixing blocks, and a wiring push rod is fixedly connected to the upper end of the outer wall on one side of the third fixing block;

[0024] The above technical solution enables the placement base to change the positions of the second and third fixing blocks via the wiring push rod.

[0025] Furthermore, a drive servo motor is fixedly connected to one side of the upper surface of the placement base, and the output end of the drive servo motor is fixedly connected to the fixed shaft.

[0026] The above technical solution enables the drive servo motor to control the rotation of the receiving roller, thereby receiving the steel cable.

[0027] Furthermore, a hook is slidably connected to the outer wall of the steel cable, and a counterweight is fixedly connected to the outer wall of the front end of the placement seat;

[0028] The above technical solution involves using hooks to lift items and using counterweights to balance the weight of the placement base.

[0029] Furthermore, a first sliding rod is fixedly connected to the inner wall of the second positioning block, and a first slider is fixedly connected to both the front end and the rear end of the outer wall of the auxiliary ring;

[0030] The above technical solution enables the auxiliary ring to move relatively smoothly on the outer shell by setting the first slide bar and the first slider.

[0031] Furthermore, baffles are fixedly connected to the outer walls of both the front and rear ends of the placement strip, and buffer blocks are fixedly connected to the outer walls of the baffles on the side closest to the placement strip.

[0032] The above technical solution restricts the movement of the placement seat by setting baffles and buffer blocks.

[0033] (III) Beneficial Effects

[0034] This invention provides an integrated design device for a double-girder bridge crane and a high-efficiency hoist. It offers the following advantages:

[0035] 1. This invention provides an integrated design device for a double-girder bridge crane and a high-efficiency hoist. Compared with most traditional integrated design devices for double-girder bridge cranes and high-efficiency hoists, this integrated design device is equipped with a protective mechanism. The auxiliary ring of the protective mechanism reciprocates under the action of the reciprocating screw, and under the action of the sprocket and chain, the reciprocating screw and the receiving roller rotate synchronously. This allows the steel cable to be wound more accurately and neatly on the receiving roller from one end to the other, and then a second layer of winding is performed. This ensures that the steel cable is wound more neatly on the receiving roller under the action of the first auxiliary pulley, thereby reducing damage caused by disordered winding of the steel cable, and also reducing damage to the steel cable caused by disordered winding when lifting heavy objects. Furthermore, under the action of the second slider, the second auxiliary pulley can adjust the angle of the steel cable according to the position of the hook, thereby reducing damage caused by deformation of the steel cable. This improves the service life and safety of the integrated design device.

[0036] 2. This invention provides an integrated design device for a double-girder bridge crane and a high-efficiency hoist. Compared with most traditional integrated design devices for double-girder bridge cranes and high-efficiency hoists, this integrated design device is equipped with a lubrication mechanism. Under the action of the first oil pump of the lubrication mechanism, lubricating oil can be injected into the steel cable of the receiving roller through the first oil outlet, thereby further reducing the damage to the steel cable during use and reducing the damage caused by mutual friction during the receiving of the steel cable. This improves the protection effect of the integrated design device for the steel cable. Furthermore, under the action of the second oil pump, the lubricating oil is also delivered to the drive gear and the teeth, which improves the stability and smoothness of the integrated design device during movement, thereby extending the service life of the integrated design device.

[0037] 3. This invention provides an integrated design device for a double-girder bridge crane and a high-efficiency hoist elevator. Compared with most traditional integrated design devices for double-girder bridge cranes and high-efficiency hoist elevators, the drive mechanism of this integrated design device is equipped with slide rails and placement bars, and the moving pulleys provide overall support, allowing the placement seat to move more smoothly. The placement seat is then driven by the meshing of drive gears, thereby reducing the pressure on the drive gears and lowering the possibility of damage due to pressure, thus extending the service life of the drive gears and improving the safety of the integrated design device when moving objects.
