Description

Technical Field

[0001] This utility model relates to the field of crane trolley equipment technology, and more specifically, to a crane trolley with an adjustable lifting frame in all directions. Background Technology

[0002] A crane trolley is the assembly that moves the suspended load. It is typically mounted on a crane and used for tasks such as material handling, suspension, loading, and unloading. The main function of the crane trolley is to move along a track to lift and transport heavy objects. With the rapid development of the transportation and lifting industry, rail-mounted cranes are widely used in large cranes and port equipment. As a crucial working mechanism within the crane, the trolley directly affects the crane's working efficiency and loading / unloading capacity.

[0003] Currently, most existing rail-mounted cranes feature a double-drum trolley setup equipped with an electro-hydraulic actuator to lift, lower, and deflect loads to a limited position. However, as lifting operations become increasingly complex and the transport and loading / unloading of goods require greater precision, the traditional rail-mounted crane's trolley, due to structural limitations, can only perform lifting, lowering, and limited-position deflection of loads. It cannot achieve displacement perpendicular to the trolley's track direction, tilting of the lifting device, or vertical angle deflection, thus failing to meet lifting requirements.

[0004] Therefore, how to provide a crane with a fully adjustable lifting frame that can adjust the position of the hoisted goods in all directions and achieve flexible adjustment of the frame positioning has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0048] This utility model provides a crane with a fully adjustable lifting frame, comprising: a crane frame; a running mechanism disposed at the four corners of the bottom surface of the crane frame; a traveling drive mechanism connected to the running mechanism; a winch mechanism disposed at the four corners of the top surface of the crane frame; a guide rail disposed on the crane frame; the guide rail being perpendicular to the traveling track of the running mechanism; a fixed pulley mechanism disposed on the guide rail; a hydraulic push rod mechanism connected to the fixed pulley mechanism; a wire rope disposed on the winch mechanism and connected to the fixed pulley mechanism; a slewing frame disposed below the crane frame and connected to the wire rope; and a lifting pin mechanism disposed at the bottom of the slewing frame. In the fully adjustable lifting trolley disclosed in this utility model, its main structure consists of a trolley frame, a running mechanism, a traveling drive mechanism, a hoisting mechanism, a guide rail, a fixed pulley mechanism, a hydraulic push rod mechanism, a wire rope, a slewing trolley, and a lifting pin mechanism. The trolley frame is a steel frame structure. The running mechanism is installed at the four corners of the bottom surface of the trolley frame. The running mechanism is set on the traveling rail. The traveling drive mechanism enables the running mechanism to reciprocate on the traveling rail, thereby driving the entire trolley to move along the traveling rail, thus achieving position adjustment of the hoisted goods in the direction of the traveling rail. Secondly, the hoisting mechanism is installed at the four corners of the top surface of the trolley frame. The hoisting mechanism has four components, which can work individually or in combination, and can operate at the same speed or at different speeds. Since one end of the wire rope is fixedly installed on the hoisting mechanism and the wire rope is connected to the slewing trolley, the slewing trolley can be tractioned by the wire rope. The lifting, lowering, and tilting of the slewing frame allow for vertical lifting and horizontal tilting adjustments to the load connected to it. Furthermore, a guide rail is installed on the crane frame, perpendicular to the travel track of the operating mechanism. A fixed pulley mechanism is movably mounted on the guide rail. Under the action of the hydraulic push rod mechanism, the fixed pulley mechanism can move back and forth along the guide rail. Since the fixed pulley mechanism is connected to the wire rope, it can cause the wire rope to swing, allowing the slewing frame to move parallel to the travel track, thus adjusting the position of the load in this direction. Moreover, the slewing frame is connected to the crane frame below via a wire rope. A lifting pin mechanism is installed at the bottom of the slewing frame to connect the load. Because the slewing frame can rotate, the position of the load can be adjusted in a planar rotation. It is evident that the technical solution provided by this utility model, compared with the prior art, can adjust the position of the suspended goods in all directions and achieve flexible adjustment of the lifting frame positioning.

[0065] like Figures 1 to 10 As shown in the figure, the lifting vehicle with fully adjustable lifting frame provided in this embodiment of the utility model includes: a lifting vehicle frame 1, a running mechanism 2, a traveling drive mechanism 3, a winch mechanism 4, a guide rail 5, a fixed pulley mechanism 6, a hydraulic push rod mechanism 7, a wire rope 8, a slewing frame 9, and a lifting pin mechanism 10.

[0066] This utility model provides a crane with an omnidirectionally adjustable lifting frame, specifically comprising: a crane frame 1; a running mechanism 2 disposed at the four corners of the bottom surface of the crane frame 1; a traveling drive mechanism 3 connected to the running mechanism 2; a winch mechanism 4 disposed at the four corners of the top surface of the crane frame 1; a guide rail 5 disposed on the crane frame 1; the guide rail 5 being perpendicular to the traveling track of the running mechanism 2; a fixed pulley mechanism 6 disposed on the guide rail 5; a hydraulic push rod mechanism 7 connected to the fixed pulley mechanism 6; a wire rope 8 disposed on the winch mechanism 4 and connected to the fixed pulley mechanism 6; a slewing frame 9 disposed below the crane frame 1 and connected to the wire rope 8; and a lifting pin mechanism 10 disposed at the bottom of the slewing frame 9. Compared with the prior art, the technical solution provided by this utility model can omnidirectionally adjust the position of the lifted goods, achieving flexible adjustment of the lifting frame positioning.

[0067] The technical solution of this utility model will be specifically described below with reference to the embodiments:

[0068] Specifically, in an embodiment of this utility model, the operating mechanism 2 includes: a wheel frame 16 disposed on the bottom surface of the crane frame 1; and a wheel assembly 17 disposed on the wheel frame 16.

[0069] like Figure 3 , 4 As shown in this embodiment of the utility model, the running mechanism 2 is installed on the travel track and is used to drive the entire trolley to move back and forth on the travel track. The running mechanism 2 is provided with four parts, and its main structure consists of the wheel frame 16 and the wheel set 17. The wheel frame 16 is installed at the four corners of the bottom surface of the crane frame 1, while the wheel set 17 is installed on the travel track and connected to the wheel frame 16, and can move back and forth on the travel track.

[0070] Specifically, in an embodiment of this utility model, the crane frame 1 includes: a trolley steel frame 11; anti-collision mechanisms 12 disposed at the four corners of the trolley steel frame 11; a horizontal wheel mechanism 13 disposed on the side wall of the trolley steel frame 11 and movably connected to the traveling track; and a first fixed seat 14 disposed on the trolley steel frame 11 and connected to the wire rope 8.

[0071] like Figure 3As shown in this embodiment of the present invention, the crane frame 1 is a steel frame structure. The crane frame 1 consists of the trolley steel frame 11, the anti-collision mechanism 12, the horizontal wheel mechanism 13, the first fixed seat 14, and the anti-shaft derailment mechanism 15. The anti-collision mechanism 12 is installed at the four corners of the trolley steel frame 11, with its ends extending beyond the edge of the trolley steel frame 11 to prevent the steel frame structure from colliding with other objects when the trolley is moving. The horizontal wheel mechanism 13 is installed at both ends of the track on the same side of the trolley steel frame 11. Through the horizontal wheel mechanism 13, sliding friction can be replaced by rolling friction. The dynamic friction reduces the resistance of the running mechanism 2 as it moves on the track, improving work efficiency and extending the service life of the running mechanism 2 to a certain extent. Secondly, the first fixed seat 14 is provided with four pieces, all of which are installed on the panel of the trolley steel frame 11. After the wire rope 8 is wound through the fixed pulley mechanism 6 and the slewing frame 9, one end is connected to the winch mechanism 4 and the other end is connected to the first fixed seat 14. The anti-broken axle derailment mechanism 15 is welded to the trolley steel frame 11, and the welding position is close to the track surface of the track, which is used to prevent the entire trolley from going off the track when the wheel axle of the wheel set 17 breaks.

[0072] Specifically, in an embodiment of this utility model, the walking drive mechanism 3 includes: a first drive motor 18 disposed on the bottom surface of the crane frame 1; a first brake disposed within the first drive motor 18; a first reducer 19 disposed at the output end of the first drive motor 18 and connected to the wheel set 17; and a torque arm mechanism 20 disposed on the first reducer 19.

[0073] like Figure 4 As shown in the embodiment of this utility model, the walking drive mechanism 3 is used to drive the running mechanism 2 to move on the walking track; wherein, the walking drive mechanism 3 is composed of the first drive motor 18, the first brake, the first reducer 19 and the torque arm mechanism 20. The first drive motor 18 is used to provide driving force, the first brake is installed inside the first drive motor 18, and the extension shaft of the first drive motor 18 is inserted into the first reducer 19, and the two are connected by a coupling; the first reducer 19 is connected and fixed to the trolley steel frame 11 through the torque arm mechanism 20, and the torque arm mechanism 20 is used to balance and stabilize the operation of the wheel set 17; and the input shaft of the wheel set 17 is inserted into the first reducer 19 and connected to the first reducer 19. The wheel set 17 can be driven by the first drive motor 18 to make the trolley reciprocate along the walking track direction.

[0074] Specifically, in an embodiment of this utility model, the hoisting mechanism 4 includes: a mounting base 21 disposed on the crane frame 1; a drum 22 disposed on the mounting base 21; a second drive motor 23 disposed on the mounting base 21; a second reducer 24 disposed at the output end of the second drive motor 23 and connected to the drum 22; and a second brake 25 disposed between the second drive motor 23 and the second reducer 24.

[0075] like Figure 5 , 6 As shown in this embodiment of the present invention, the winch mechanism 4 is connected to the wire rope 8 and is used to extend or retract the wire rope 8 to pull the slewing frame connected to the wire rope 8 to move upward or downward. The winch mechanism 4 consists of the mounting base 21, the drum 22, the second drive motor 23, the second reducer 24, and the second brake 25. The second drive motor 23 and the drum 22 are respectively mounted on the left and right ends of the mounting base 21. The wire rope 8 is wound on the drum 22. The drum 22 is connected to the second drive motor 23 through the second reducer 24, and the driving force of the second drive motor 23 is transmitted to the drum 22, causing the drum 22 to rotate on a fixed axis, so that the wire rope 8 wound on the drum 22 can extend or retract.

[0076] Specifically, in the embodiments of this utility model, the hoisting mechanism 4 is provided with four components: a first hoisting mechanism 40 and a second hoisting mechanism 41 located on the left side of the crane frame 1; and a third hoisting mechanism 42 and a fourth hoisting mechanism 43 located on the right side of the crane frame 1.

[0077] like Figure 10As shown in the embodiment of this utility model, the arrangement scheme of the crane with a fully adjustable lifting frame is specifically described. Four winch mechanisms 4 are provided, which can operate individually, in combination, at the same speed, or at a different speed. In this embodiment, when the drums 22 of the first, second, third, and fourth winch mechanisms 43 operate at the same speed and in the same direction, the hoisted goods can be lifted and lowered normally under the traction of the wire rope 8. When the drums 22 of the first winch mechanism 40 and the second winch mechanism 41 operate at the same speed and in the same direction, and the drums 22 of the third winch mechanism 42 and the fourth winch mechanism 43 do not operate, the hoisted goods can be tilted along the sides of the drums 22 of the first and second winch mechanisms 41. Similarly, if the drums 22 of the first, second, third, and fourth winch mechanisms 43 do not operate, the hoisted goods can be tilted along the sides of the drums 22 of the first and second winch mechanisms 41. When the drums 22 of the three winches 42 move at the same speed and in the same direction, and the drums 22 of the second and fourth winches 43 do not move, the hoisted goods can be tilted along the drums 22 of the first and third winches 42. When the drums 22 of the first, second, third and fourth winches 43 move at different speeds and in the same direction, the drums 22 of the first and second winches 41 move faster than the drums 22 of the third and fourth winches 43. This allows the hoisted goods to tilt along the drums 22 of the third and fourth winches 43 during lifting and lowering. Based on the above principle, tilting can also be achieved along the drums 22 of the first and third winches 42, the drums 22 of the second and fourth winches 43, and the drums 22 of the first and second winches 41.

[0078] Specifically, in an embodiment of this utility model, the guide rail 5 includes: a first guide rail; a second guide rail arranged parallel to the first guide rail; and four fixed pulley mechanisms 6. The four fixed pulley mechanisms 6 are: a first fixed pulley mechanism 44 and a second fixed pulley mechanism 45 arranged on the first guide rail; and a third fixed pulley mechanism 46 and a fourth fixed pulley mechanism 47 arranged on the second guide rail.

[0079] More specifically, four fixed pulley mechanisms 6 are provided, each of which is connected to one hydraulic push rod mechanism 7. Under the interaction of the fixed pulley mechanisms 6 and the hydraulic push rod mechanisms 7, the suspended cargo can be translated perpendicularly to the direction of the travel track. Furthermore, when the first fixed pulley mechanism 44 and the second fixed pulley mechanism 45 move in the same direction, and the third fixed pulley mechanism 46 and the fourth fixed pulley mechanism 47 move in the same direction, and the first and second fixed pulley mechanisms 45 move in opposite directions to the third and fourth fixed pulley mechanisms 47, the suspended cargo can be deflected. This action can adjust the horizontal deflection of the cargo to a small extent when the slewing frame 9 is not in motion. Secondly, when the first fixed pulley mechanism 44 and the third fixed pulley mechanism 46 move in the same direction, and the second fixed pulley mechanism 45 and the fourth fixed pulley mechanism 47 move in the same direction, and the first and third fixed pulley mechanisms 46 move in opposite directions to the second and fourth fixed pulley mechanisms 47, the sway angle of the wire rope 8 can be changed, reducing the sway of the suspended object.

[0080] Specifically, in an embodiment of this utility model, the fixed pulley mechanism 6 includes: a slider 26 disposed on the guide rail 5; a support mounting base 27 disposed on the slider 26; a fixed pulley group 28 disposed on the support mounting base 27; and a mounting joint 29 disposed on the side wall of the support mounting base 27 and connected to the hydraulic push rod mechanism 7.

[0081] like Figure 7 , 8 As shown in this embodiment of the present invention, the fixed pulley mechanism 6 consists of a slider 26, a support mounting base 27, a fixed pulley assembly 28, and a mounting joint 29. The slider 26 is movably connected to the guide rail 5. The support mounting base 27 is mounted on the slider 26. The fixed pulley assembly 28 is disposed on the support mounting base 27. The fixed pulley assembly 28 is connected to the steel wire rope 8. When the fixed pulley assembly 28 moves, it can drive the steel wire rope 8 to move together.

[0082] Specifically, in an embodiment of this utility model, the hydraulic push rod mechanism 7 includes: a second fixed seat 30 disposed on the crane frame 1; a hydraulic cylinder 31 with one end connected to the second fixed seat 30 and the other end connected to the mounting joint 29; and a drive assembly connected to the hydraulic cylinder 31.

[0083] Specifically, in an embodiment of this utility model, the slewing hanger 9 includes: a balance beam 32; a movable pulley group 33 disposed on the balance beam 32 and connected to the wire rope 8; a hanging beam 34 disposed below the balance beam 32; a slewing support assembly 35 connecting the balance beam 32 and the hanging beam 34; a third drive motor 36 disposed on the balance beam 32; a third reducer 37 connected to the third drive motor 36; and a slewing pinion 38 disposed at the output end of the third reducer 37 and connected to the slewing support assembly 35.

[0084] like Figure 9 As shown in this embodiment of the utility model, the slewing frame 9 is used to drive the hoisted goods to perform planar slewing motion. The slewing frame 9 is pulled by the wire rope 8 and consists of the movable pulley group 33, the balance beam 32, the lifting beam 34, the third drive motor 36, the third reducer 37, the slewing pinion 38, the slewing support assembly 35, and the lifting pin mechanism 10. The movable pulley group 33 is connected to the wire rope 8 and is connected to the balance beam 32 by a pin. The balance beam 32 and the lifting beam 34 are connected by bolts through the slewing support assembly 35. The third drive motor 36, the third reducer 37, and the slewing pinion 38 are assembled and installed on the balance beam 32 by a support. The third drive motor 36 drives the slewing pinion 38, thereby driving the slewing support assembly 35 to perform fixed-axis movement, causing the lifting beam 34 to perform slewing motion.

[0085] Specifically, in the embodiments of this utility model, it further includes: an anti-shaft derailment mechanism 15 disposed on the trolley steel frame 11.

[0086] More specifically, in an embodiment of this utility model, the crane with an omnidirectional adjustable lifting frame further includes: an electronic control system 39 disposed on the crane frame 1 and communicatively connected to the traveling drive mechanism 3, the winch mechanism 4, the hydraulic push rod mechanism 7, the slewing frame 9, and the lifting pin mechanism 10; and a control panel communicatively connected to the electronic control system 39.

[0087] In this embodiment of the utility model, the electronic control system 39 controls the operating mechanism 2, the four sets of hoisting mechanisms 4, the four sets of hydraulic push rod mechanisms 7 and the slewing frame 9 respectively, and each mechanism can be linked or act independently.

[0088] Specifically, in an embodiment of this utility model, a first weight sensor is provided inside the lifting mechanism 10; a second weight sensor is provided inside the first fixed base 14; the first weight sensor and the second weight sensor are communicatively connected to the electronic control system 39; the electronic control system 39 controls the fixed-axis rotation speed of the hoisting mechanism 4 through frequency conversion.

[0089] The first and second weight sensors are connected to the electronic control system 39, which can detect the load in real time, preset off-center load and overload alarms, and transmit the data to the control screen for display in real time.

[0090] As described above, the fully adjustable lifting frame of the crane disclosed in this utility model comprises a crane frame 1, a running mechanism 2, a traveling drive mechanism 3, a hoisting mechanism 4, a guide rail 5, a fixed pulley mechanism 6, a hydraulic push rod mechanism 7, a wire rope 8, a slewing frame 9, and a lifting pin mechanism 10. The crane frame 1 is a steel frame structure. The running mechanism 2 is installed at the four corners of the bottom surface of the crane frame 1. The running mechanism 2 is mounted on the traveling rail, and the traveling drive mechanism 3 enables the running mechanism 2 to reciprocate on the traveling rail. This causes the entire trolley to move along the travel track, allowing for position adjustment of the hoisted goods along the travel track. Secondly, the hoisting mechanisms 4 are installed at the four corners of the top surface of the crane frame 1. There are four hoisting mechanisms 4, which can operate individually or in combination, and can run at the same speed or at different speeds. Since one end of the wire rope 8 is fixedly installed on the hoisting mechanism 4 and connected to the slewing frame 9, the slewing frame 9 can be raised, lowered, and tilted by the traction of the wire rope 8, allowing the hoisted goods connected to the slewing frame 9 to move. The loading and unloading mechanism allows for vertical lifting and horizontal tilting adjustments. Furthermore, a guide rail 5 is mounted on the crane frame 1, perpendicular to the travel track of the operating mechanism 2. A fixed pulley mechanism 6 is movably mounted on the guide rail 5. Under the action of the hydraulic push rod mechanism 7, the fixed pulley mechanism 6 can move back and forth along the guide rail 5. Since the fixed pulley mechanism 6 is connected to the wire rope 8, it can drive the wire rope 8 to swing along with the fixed pulley mechanism 6, allowing the rotating crane 9 to move in a direction perpendicular to the travel track. By moving parallel to the crane frame 1, the position of the hoisted goods can be adjusted in this direction. Furthermore, the slewing frame 9 is connected to the crane frame 1 via the wire rope 8. The bottom of the slewing frame 9 is equipped with the lifting pin mechanism 10, which is used to connect the hoisted goods. Since the slewing frame 9 can rotate, the position of the hoisted goods in the plane can be adjusted using the slewing frame 9. As described above, the technical solution provided by this utility model, compared with the prior art, can adjust the position of the hoisted goods in all directions and achieve flexible adjustment of the crane positioning.

[0091] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
