Description

Technical Field

[0001] This invention relates to the field of cable crane hoisting technology, specifically to a cable crane lifting and hoisting device. Background Technology

[0002] Dams have a wide range of applications and profound impacts in the water conservancy industry, mainly used for flood control, water supply, power generation, and other purposes. Newly built dams are often quite tall and large in size. Commonly used equipment such as tower cranes and crawler cranes are generally insufficient for the concrete pouring of dams. Large cable cranes are increasingly used in the concrete pouring of concrete gravity dams and arch dams, and can directly solve the problem of horizontal and vertical transportation of dam concrete.

[0003] While cable cranes can solve the problem of dam concrete pouring, their installation is quite difficult and requires the assistance of large truck cranes. Dam sites are often located in steep mountainous terrain with narrow riverbeds and relatively intact bedrock on both banks. The installation with large truck cranes necessitates addressing road access issues. With increasing societal progress, water conservation requirements and stricter controls on the destruction of mountain forests, coupled with stringent land acquisition regulations by natural resources bureaus, have created numerous obstacles to the construction of access roads, making it impossible to build new roads to address the problem of transporting large equipment uphill. Furthermore, the high lifting height required for truck cranes means that heavy objects are prone to swaying during the lifting process, and manual adjustments are impossible, leading to inaccurate positioning and higher lifting risks.

[0004] Based on this, the present invention designs a cable crane lifting and hoisting device to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a cable crane lifting and hoisting device to solve the problems mentioned in the background art, such as the difficulty in installing large truck cranes and solving road problems, the high hoisting height required for truck cranes, the tendency of heavy objects to swing during hoisting, the inability to manually adjust them, resulting in inaccurate hoisting positions and high hoisting risks.

[0006] To achieve the above objectives, the present invention provides the following technical solution: It includes a ramp lifting section and an installation lifting section. The ramp lifting section includes a track and a lifting vehicle. The lifting vehicle has a horizontal support platform, and the lifting vehicle is pulled up along the track by a vehicle body winch. The installation lifting section includes a V-shaped swing arm, which is rotatably installed inside the track. A connecting hook is installed at the end of the V-shaped swing arm, and the connecting hook is used to hook a heavy object on the lifting vehicle and lift it by rotating the V-shaped swing arm.

[0007] As a further embodiment of the present invention, it also includes a slope base, a ramp machine track, and a mobile terminal platform. The slope base is cast according to the site conditions, and the ramp machine track and the mobile terminal platform are both cast on site. The lifting vehicle has a right-angled triangular structure and multiple support rods are fixedly installed inside.

[0008] As a further embodiment of the present invention, the A-frame swing arm is lifted by a swing arm winch via a hoisting fixed pulley. The hoisting fixed pulley is installed on the rock surface of the mountain. An end fixed pulley is installed at the end of the A-frame swing arm. A car body fixed pulley is rotatably installed at the end of the lifting vehicle. A lifting fixed pulley is also installed on the rock surface of the mountain. The wire rope of the swing arm winch passes through the hoisting fixed pulley and the end fixed pulley in sequence to lift and swing the A-frame swing arm. The wire rope of the car body winch passes through the car body fixed pulley and the lifting fixed pulley in sequence to lift the lifting vehicle up along the track.

[0009] As a further embodiment of the present invention, both the vehicle body winch and the swing arm winch are mounted on the mobile end platform, and the upper end of the mobile end platform is equipped with a vehicle body reversing wheel and a swing arm reversing wheel. A transition wheel is rotatably mounted at the end of the herringbone swing arm. The wire rope passing through the lifting fixed pulley passes through the transition wheel and the swing arm reversing wheel to reach the swing arm winch. The wire rope passing through the lifting fixed pulley goes around the vehicle body reversing wheel and is connected to the vehicle body winch.

[0010] As a further embodiment of the present invention, the bottom end of the A-frame swing arm is rotatably connected to the inclined machine track via a rotating base, and a hand-operated hoist is installed at the end of the A-frame swing arm, with a connecting hook installed at the wire rope of the hand-operated hoist.

[0011] As a further embodiment of the present invention, sleepers are installed between the track and the slope base, and a set of anti-derailment wheels are rotatably installed at the bottom of the lifting vehicle, and the anti-derailment wheels roll along the track.

[0012] As a further embodiment of the present invention, the track is an I-beam, and the track is installed on the slope base by a mounting block. The top of the mounting block is provided with a positioning claw extending into the track, and a safety rod is rotatably provided on the anti-detachment wheel. The safety rod cooperates with the positioning claw to prevent the lifting vehicle from slipping during the lifting process.

[0013] As a further embodiment of the present invention, an extension shaft is rotatably connected to the center of the anti-detachment wheel, and a vertical hanging plate is fixedly connected to the outside of the extension shaft. The safety bar is rotatably connected to the inner side of the vertical hanging plate through an eccentric shaft, and the eccentric shaft is located near the upper end of the safety bar.

[0014] As a further embodiment of the present invention, a magnetic suction plate is fixedly connected to the side wall of the vertical hanging plate, and the magnetic suction plate extends inward and has an upper and lower overlapping part with the safety bar, and the magnetic suction plate is used to fix the safety bar.

[0015] As a further embodiment of the present invention, a guide ramp is fixedly installed on the inner side of the top of the track. When the hoisting vehicle approaches the end of the track, the safety rod contacts the guide ramp and rotates. The guide ramp is also used to block the safety rod from continuing to pass, thereby limiting the position of the hoisting vehicle.

[0016] Compared with the prior art, the beneficial effects of the present invention are: The lifting vehicle smoothly lifts the load, and with the secondary lifting and swing displacement of the A-frame swing arm, the heavy object is transported to the designated location. It is suitable for transporting heavy objects over long distances and with a large span. The lifting device itself is simple, requires no complicated installation methods, and has a low barrier to entry.

[0017] Lifting vehicles transport heavy objects along slopes, allowing for precise control of the transport path, avoiding damage from swaying of the heavy objects during hoisting, and mitigating the risks associated with reduced hoisting height. This approach is both safe and efficient.

[0018] The two-stage transportation system uses a mobile platform at the top of the track as a connecting and controllable platform, which facilitates the installation and control of the hoisting equipment, makes it easy for personnel to operate, and makes manual operation on the mobile platform relatively safe.

[0019] The simple mechanism enables both horizontal and vertical movement. The simple two-pole design allows for a relatively open space with few obstructions, facilitating the accurate hoisting of heavy objects to the required position. The installation cost is low, and the installation accuracy is guaranteed. This approach is more effective in controlling the damage to the mountainside and the investment costs caused by building new roads. Attached Figure Description

[0022] Please see Figure 1-9 The technical solution provided by the present invention is as follows: it includes a ramp lifting section and an installation lifting section. The ramp lifting section includes a track 3 and a lifting vehicle 1. The lifting vehicle 1 has a horizontal support platform 2. The lifting vehicle 1 is pulled up along the track 3 by a vehicle body winch. The installation lifting section includes a herringbone swing arm 4. The herringbone swing arm 4 is rotatably installed in the track 3. A connecting hook 5 is installed at the end of the herringbone swing arm 4. The connecting hook 5 is used to hook the heavy object on the lifting vehicle 1 and lift it by rotating the herringbone swing arm 4.

[0023] Please see Figures 5-6 First, the heavy object to be lifted, such as the components of the cable machine, is placed on the support platform 2. The hoisting car 1 is pulled up along the track 3 by the car body winch winding the steel wire rope, thereby stabilizing the heavy object. When the hoisting car 1 reaches the end of the track 3, the hoisting car 1 stops at the current position and hooks the connecting hook 5 to the heavy object. Then, the swing arm winch winds the steel wire rope to pull the end of the A-frame swing arm 4 to make it rotate and stand up, thereby lifting the heavy object away from the hoisting car 1, so that the heavy object reaches the inclined machine track, and the inclined mechanism components are connected and installed in the track.

[0024] The lifting vehicle 1 smoothly lifts the load, and with the secondary lifting and swing displacement of the A-frame swing arm 4, the heavy object is transported to the designated position, which is suitable for transporting heavy objects with large spans and high distances. The lifting vehicle 1 transports the heavy object along the slope, which can accurately control the transport path and avoid damage caused by the swing of the heavy object during hoisting and the risks caused by reducing the hoisting height, making it both safe and efficient. The two-stage transport means that the mobile end platform at the upper end of the track 3 can be used as a connecting and controllable platform, which is conducive to the installation and control of the hoisting device and easy for personnel to operate. Manual operation on the mobile end platform is relatively safe.

[0025] The A-frame swing arm 4 rotates to lift and pull up heavy objects. Through a simple mechanism, it achieves both horizontal movement and vertical movement. At the same time, the simple two arms allow for a relatively open space with few obstructions, which is conducive to accurately hoisting heavy objects to the required position.

[0026] This includes a slope base, a ramp machine track, and a mobile platform. The slope base is poured according to the site conditions, while the ramp machine track and the mobile platform are poured on-site. The lifting vehicle 1 has a right-angled triangular structure and multiple support rods 6 are fixedly installed inside.

[0027] The hoisting vehicle 1 is equipped with a horizontal support platform 2, which facilitates the placement of cable mechanism components. In conjunction with the slope of the track 3, the support platform 2 remains horizontal during the movement of the hoisting vehicle 1, thus stably supporting the heavy object as it rises. Multiple support rods 6 are installed inside, which makes the overall structure of the hoisting vehicle 1 have high strength and can support heavy objects without collapsing.

[0028] Analyze the terrain to determine the slope of the ramp machine foundation. After clarifying the slope of the ramp machine foundation, use a combination of small excavators and manual labor to excavate and shape the foundation of the ramp machine to form the ramp base. After simple trimming, the track 3 is erected by a combination of concrete formwork pouring and steel frame support.

[0029] The A-frame swing arm 4 is lifted by a swing arm winch via a hoisting fixed pulley 7, which is installed on the rock face of the mountain. An end fixed pulley 8 is installed at the end of the A-frame swing arm 4. A car body fixed pulley 9 is rotatably installed at the end of the lifting car 1. A lifting fixed pulley 10 is also installed on the rock face of the mountain. The wire rope of the swing arm winch passes through the hoisting fixed pulley 7 and the end fixed pulley 8 in sequence to winch and pull up the A-frame swing arm 4 and swing it. The wire rope of the car body winch passes through the car body fixed pulley 9 and the lifting fixed pulley 10 in sequence to winch the lifting car 1 and lift it up along the track 3.

[0030] The vehicle body winch and the swing arm winch are both installed on the mobile end platform. The upper part of the mobile end platform is equipped with a vehicle body reversing wheel 11 and a swing arm reversing wheel 12. The end of the herringbone swing arm 4 is rotatably equipped with a transition wheel 13. The steel wire rope passing through the lifting fixed pulley 10 passes through the transition wheel 13 and the swing arm reversing wheel 12 to reach the swing arm winch. The steel wire rope passing through the lifting fixed pulley 10 goes around the vehicle body reversing wheel 11 and is connected to the vehicle body winch.

[0031] Based on the maximum weight of a single cable crane component provided by the manufacturer, determine the material and equipment parameters for the hoisting vehicle 1, fixed pulley block, wire rope, A-frame swing arm 4, winch, etc., and verify the safety performance of the linkage of each piece of equipment.

[0032] The slope of the installed track 3 must be the same as the slope of the steel wire rope that moves the traction lifting vehicle 1, thus determining the position of the top lifting fixed pulley 10. The lifting fixed pulley 10 is a double-door 25t fixed pulley assembly. The car body fixed pulley 9 at the front end of the lifting vehicle 1 is a double-door 25t fixed pulley assembly, connected to the lifting vehicle 1 via shackles. The lifting fixed pulley 10 and the car body fixed pulley 9 are connected by four steel wire ropes of 17.5-6*19 diameter. Then, the car body reversing wheel 11 is installed at the position of the moving end platform. The car body reversing wheel 11 is a fixed pulley. The car body fixed pulley 9, the lifting fixed pulley 10, and the car body reversing wheel 11 are connected to a 10t car body winch via steel wire ropes. The car body winch is fixed to the moving end platform.

[0033] The centerline of track 3 and the centerline of the A-frame swing arm 4 must be the same straight line. The position of the rotating base 14 of the A-frame swing arm 4 is determined according to the distance between the end point of track 3 and the mobile end platform, and anchor rods are installed to rigidly connect it.

[0034] The A-frame swing arm model 4 uses two seamless steel pipes with a diameter of 35 mm and a wall thickness of 14 mm. Four steel wire ropes with a diameter of 19.5 mm are connected to the hook ring at the upper part of the A-frame swing arm 4 with shackles. The hoisting fixed pulley 7 and the end fixed pulley 8 are 25t pulley blocks. The swing arm reversing wheel 12 at the mobile end platform position is connected to the swing arm winch through the hoisting fixed pulley 7. The swing arm winch is a 10t pitch winch and is fixed to the mobile end platform.

[0035] By using steel wire ropes and pulleys to change direction, the hoisting car 1 moves along the track 3 and the A-frame swing arm 4 tilts, thus simplifying the equipment, making the hoisting space more open and the obstacles fewer, which is conducive to hoisting heavy objects and reaching the expected position.

[0036] The bottom end of the A-frame swing arm 4 is rotatably connected to the inclined machine track via the rotating base 14, and a hand chain hoist 15 is installed at the end of the A-frame swing arm 4. The connecting hook 5 is installed at the wire rope of the hand chain hoist 15.

[0037] Two 10t hand chain hoists 15 are connected to the lower hook ring of the A-frame lever 4 by shackles and equipped with four steel wire cables with a diameter of 17.5 mm.

[0038] When used in conjunction with the chain hoist 15, it can be used to change the height of the load during the hoisting of the A-frame swing arm 4, so that the load can reach a suitable height, which facilitates the hoisting and assembly of the cable mechanism components.

[0039] Among them, sleepers 16 are installed between track 3 and the slope base, and a set of anti-derailment wheels 17 are rotatably installed at the bottom of the lifting car 1, and the anti-derailment wheels 17 roll along track 3.

[0040] The track 3 is an I-beam. The track 3 is installed on the slope base by the mounting block 25. The top of the mounting block 25 is provided with a positioning claw 18 extending into the track 3. The anti-detachment wheel 17 is provided with a safety bar 19 that rotates outward. The safety bar 19 cooperates with the positioning claw 18 to prevent the lifting vehicle 1 from slipping during the lifting process.

[0041] Among them, the anti-detachment wheel 17 is rotatably connected to the center of the extension shaft 20, and the extension shaft 20 is fixedly connected to the outside of the vertical hanging plate 21. The safety bar 19 is rotatably connected to the inside of the vertical hanging plate 21 through the eccentric shaft 22, and the eccentric shaft 22 is located near the upper end of the safety bar 19.

[0042] The vertical hanging plate 21 is fixedly connected to a magnetic suction plate 23 on its side wall. The magnetic suction plate 23 extends inward and has an overlapping part with the safety bar 19. The magnetic suction plate 23 is used to fix the safety bar 19.

[0043] A guide plate 24 is fixedly installed on the inner side of the top of the track 3. When the lifting car 1 approaches the end of the track 3, the safety rod 19 contacts the guide plate 24 and rotates. The guide plate 24 is also used to block the safety rod 19 from continuing to pass, thereby limiting the position of the lifting car 1.

[0044] like Figure 2 , Figure 8 As shown, when the hoisting vehicle 1 rises along the track 3, the vertical hanging plate 21 remains vertically hanging under the action of gravity. Since the connection position between the eccentric shaft 22 and the safety rod 19 is not centered and the tail end is heavier, the tail end of the safety rod 19 will naturally droop under the weight of the safety rod 19. The tail end of the safety rod 19 is drooping and located in the groove outside the track 3 of the I-beam. The track 3 can be fixedly installed to the inclined base surface by the mounting block 25. At the same time, the mounting block 25 has a positioning claw 18 that extends into the track 3 of the I-beam. When the hoisting vehicle 1 moves, the safety rod 19 is pulled along the groove outside the track 3. When it reaches the positioning claw 18, it is lifted and rotated, and then smoothly passes the positioning claw 18. The hoisting vehicle 1 can be smoothly pulled up.

[0045] When the hoisting trolley 1 stops, the tail end of the safety bar 19 will abut against the positioning claw 18. Due to the gravity of the hoisting trolley 1, it tends to slide down, which pulls the tail end of the safety bar 19 to rotate downwards, thus firmly abutting against the positioning claw 18 and preventing it from moving down. This prevents the hoisting trolley 1 from sliding down, thus playing a safety protection role in preventing the hoisting trolley 1 from sliding down unexpectedly. At the same time, when connected to the A-frame swing arm 4, the hoisting trolley 1 can stay at the end of the track 3, which facilitates the hooking operation of heavy objects. At this time, the safety bar 19 plays the role of positioning the hoisting trolley 1, adapting to the hoisting needs, and can share the force of the wire rope when stopped, while providing safety protection.

[0046] like Figure 8 , Figure 9As shown, when the lifting vehicle 1 moves to the end of the track to complete the connection and hoisting of the heavy object, by pulling the lifting vehicle 1 forward, the safety bar 19 is squeezed and rotated downward under the action of the guide inclined plate 24, thereby lifting the tail end of the safety bar 19 and raising it to the position of adhering to the magnetic suction plate 23, fixing the safety bar 19 in the state of the tail end raised, so that the safety bar 19 can pass smoothly through the positioning claw 18, and the lifting vehicle 1 can smoothly slide down to the bottom to transport the new component.

[0047] At the same time, the guide ramp 24 blocks the front end of the track 3, and the safety rod 19 cannot cross the guide ramp 24, which limits the extreme position of the lifting car 1, avoids excessive pulling that causes the lifting car 1 to exceed the track, provides limit assistance, and facilitates the safe and efficient use of the lifting car 1.
