Description

Technical Field

[0001] This utility model relates to the field of hoisting tools, and in particular to a hoisting and handling tool for field operations without grid power. Background Technology

[0002] In field operations, such as forestry timber handling, geological exploration equipment transfer, beehive relocation, and outdoor engineering material hoisting, there are often problems such as no grid power supply, complex operating environments, and a lack of large-scale lifting auxiliary equipment. At this time, extremely high requirements are placed on the power adaptability, portability, and ease of assembly of hoisting tools.

[0003] Currently, there are two main solutions for hoisting operations in the field without grid power: one is to rely on large vehicle-mounted cranes, but their rental costs are high and their accessibility is limited by complex terrain (such as mountains and forests), making flexible deployment difficult; the other is to use manual handling, which involves lifting and carrying heavy objects by hand, which is not only labor-intensive and inefficient, but also prone to equipment damage or personnel injury due to collisions with heavy objects.

[0004] To address the aforementioned issues, the prior art, patent CN214828557U, discloses a beehive relocation and lifting tool. Firstly, it employs a gasoline engine-driven cable winding mechanism, eliminating reliance on grid power and adapting to power-free outdoor environments. This prior art effectively improves the efficiency of beehive relocation in the field, avoiding the high costs of large cranes and the high intensity of manual handling.

[0005] However, the aforementioned cited patents and existing similar small-scale field lifting tools are insufficient to fully meet the core needs of rapid deployment and flexible transportation in field operations, and still have the following problems: 1. Inconvenient disassembly and transportation of equipment: The boom, cable reel mechanism, and crane frame are highly interconnected, making it difficult to carry manually when there are no transport vehicles available in the field, especially unsuitable for mountainous or forested areas where manual transport is required; 2. Poor assembly convenience: The inner body of the crane serves as the connecting central axis, and its design length is relatively long. During assembly, the outer body of the crane, which integrates the boom, gasoline engine, and winch, must be raised to a height higher than the length of the inner body to achieve the fitting of the outer and inner bodies. The lifting action is labor-intensive, the assembly efficiency is low, and there is even a safety hazard of parts slipping; 3. The bidirectional self-locking winch used in existing patented technologies has the following defects: the lifting speed is slow for heavy loads, and the lifting speed is light for light loads, which cannot simultaneously meet the requirements of heavy lifting capacity and high speed, affecting the crane's lifting capacity. Utility Model Content

[0006] This utility model proposes a handling and hoisting tool for field operations without grid power, which solves the problems of inconvenient equipment disassembly and handling, poor assembly convenience, and light lifting weight in the prior art.

[0007] The technical solution of this utility model is implemented as follows: A lifting and transport tool for field operations without grid power includes a crane frame and a crane chassis. The crane frame has a central shaft outer sleeve, and the crane chassis has a chassis central shaft. The chassis central shaft and the central shaft outer sleeve are interlocked. The length of the chassis central shaft is less than half the length of the central shaft outer sleeve. A rotary drive mechanism is provided between the crane frame and the crane chassis. A boom, a cable reel assembly, and a power generation assembly are detachably connected to the crane frame. Because the chassis central shaft is relatively short, during assembly, only the crane frame needs to be raised slightly above the chassis central shaft height to achieve the interlocking connection between the chassis central shaft and the central shaft outer sleeve, eliminating the need for auxiliary equipment and significantly improving deployment efficiency in field operations.

[0008] The crane frame includes a cuboid frame, with a central shaft outer tube vertically positioned in the middle of the cuboid frame. A boom support leg is connected to the top surface of the front of the cuboid frame, and the boom support leg is connected to the lower middle part of the boom. The rear end of the boom is connected to the upper end of the central shaft outer tube. The boom support leg provides support for the boom, and the lower connection point of the boom support leg is located on the top surface of the front end of the cuboid frame. Moving the boom's fulcrum forward increases the length of the rear body of the crane and the length of the boom's power arm, effectively improving the crane's lifting capacity and preventing the lifting equipment from tilting forward.

[0009] The lower middle part of the boom is provided with a lug plate, and the boom support leg is connected to the lug plate pin. The front end of the boom is provided with a pulley connecting seat, a pulley is rotatably installed at the pulley connecting seat, a lifting rope is wound on the pulley, the front end of the lifting rope is connected to a hook, and the rear end of the lifting rope is connected to a cable take-up assembly.

[0010] The cable winding assembly includes a winch, which is detachably mounted on the top surface of the rear of the cuboid frame. The hoisting rope is connected to the winch. The winch can be started and rotated in both forward and reverse directions to wind and unwind the hoisting rope.

[0011] The bottom of the crane frame is equipped with frame support wheels, and the cuboid frame is equipped with handles.

[0012] The crane chassis includes a circular track, with the chassis central axis positioned at the center of the circular track. The chassis central axis is connected to the circular track via chassis support rods; the frame support wheels cooperate with the circular track.

[0013] The rotary drive mechanism includes a rotary motor and a gear disk. The rotary motor is mounted on the crane frame, and the gear disk is mounted on the central shaft of the chassis. The output end of the rotary motor is provided with a gear shaft, which meshes with the gear disk.

[0014] The power generation assembly includes a gasoline generator and a distribution box. The gasoline generator is located at the lower front part of the cuboid frame, and the distribution box is located on the upper part of the outer sleeve of the frame's central axis. The gasoline generator supplies power to the winch and rotating motor through the distribution box. A mesh for placing counterweights is located at the rear of the cuboid frame. The distribution box contains an electrical switch, an AC contactor, a frequency converter, and a generator voltage regulator. The frequency converter regulates the speed of the rotating motor, the AC contactor starts the motor, and the voltage regulator stabilizes the output voltage of the gasoline generator. The gasoline generator supplies power to the winch.

[0015] The inner sleeve of the central shaft is provided with a support baffle, the lower side of which is provided with a groove, and the upper end of the central shaft of the chassis is provided with a steel ball, which cooperates with the groove.

[0016] The bottom of the circular track is equipped with chassis support wheels, which facilitates the transfer and handling of the crane chassis.

[0017] The beneficial effects of this utility model are: reducing the labor intensity of assembly, improving the efficiency of field deployment, increasing the lifting weight of the crane, and designing the length of the chassis central shaft to be less than half the length of the central shaft outer tube. During assembly, the crane frame only needs to be raised to slightly higher than the height of the chassis central shaft to achieve the insertion and matching of the chassis central shaft and the central shaft outer tube. No auxiliary equipment is required, which greatly improves the deployment efficiency of field operations and avoids the safety hazard of components slipping off when raised high.

[0018] Improved disassembly convenience, suitable for manual handling in the field; during handling, each core component can be disassembled into independent and moderately weighted parts such as crane frame, boom, winch, gasoline generator, and crane chassis, which is convenient for manual handling, especially suitable for field scenarios such as mountains and forests where there are no transport vehicles, solving the problems of high component integration and difficulty in manual carrying in existing technologies.

[0019] To enhance the lifting capacity of the hoisting equipment, the rear end of the boom is connected to the middle of the hoisting frame, and boom support legs are installed on the top surface of the front of the hoisting frame. The boom support legs provide support for the boom, moving the fulcrum of the boom forward and lengthening the power boom of the crane, effectively improving the crane's lifting capacity and preventing the hoisting equipment from tilting forward.

[0020] A rotary drive mechanism is installed between the crane frame and the crane chassis. Operators only need to press the control button to make the crane frame rotate smoothly on the crane chassis, saving the physical effort of manual pushing. Especially in scenarios with large counterweights, it can greatly reduce the amount of labor required for operation, taking into account both the need for heavy lifting and labor-saving operation.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1, such as Figure 1As shown, a lifting and handling tool for field operations without grid power includes a crane frame 1 and a crane chassis 2. The crane frame 1 has a central shaft outer tube 12, and the crane chassis 2 has a chassis central shaft 24. The chassis central shaft 24 is inserted into the central shaft outer tube 12, and the length of the chassis central shaft 24 is less than half the length of the central shaft outer tube 12. A rotary drive mechanism is provided between the crane frame 1 and the crane chassis 2. A boom 3, a cable take-up assembly, and a power generation assembly are detachably connected to the crane frame 1. Because the chassis central shaft 24 is relatively short, during the assembly of the lifting tool, only the crane frame 1 needs to be raised to a height slightly higher than the chassis central shaft 24 to achieve the insertion and engagement of the chassis central shaft 24 with the central shaft outer tube 12, without the need for auxiliary equipment, significantly improving the deployment efficiency of field operations.

[0026] Furthermore, such as Figure 2 As shown, the crane frame 1 includes a cuboid frame 11, with a central shaft outer sleeve 12 vertically positioned in the middle of the cuboid frame 11. A boom support leg 4 is connected to the top surface of the front part of the cuboid frame 11, and the boom support leg 4 is connected to the lower middle part of the boom 3. The rear end of the boom 3 is connected to the upper end of the central shaft outer sleeve 12. Specifically, the cuboid frame 11 is constructed from welded square steel tubing. A support leg connecting seat 13 is provided on the top surface of the front part of the cuboid frame 11, and the lower end of the boom support leg 4 is connected to the support leg connecting seat 13 via a pin. A boom connecting seat 14 is provided at the upper end of the central shaft outer sleeve 12, and the rear end of the boom 3 is connected to the boom connecting seat 14 via a pin. The boom support leg 4 provides support for the boom 3, causing the fulcrum of the boom 3 to move forward, thus lengthening the crane's boom length, effectively improving the crane's lifting capacity, and effectively preventing the lifting equipment from tilting forward.

[0027] Furthermore, such as Figure 5 As shown, the lower middle part of the boom 3 is provided with an ear plate 31, and the boom support leg 4 is connected to the ear plate 31 by a pin. The front end of the boom 3 is provided with a pulley connecting seat 32, and a pulley is rotatably installed at the pulley connecting seat 32. A lifting rope 8 is wound on the pulley, and the front end of the lifting rope 8 is connected to a hook 9. The rear end of the lifting rope 8 is connected to the take-up assembly. Boom support legs 4 are provided on both the left and right sides of the boom 3. The boom support legs 4, boom 3, and crane frame 1 are arranged in a triangle, making the boom 3 more stable when installed on the crane frame 1. The take-up assembly includes a winch 5. This type of winch 5 has a high rotation speed and heavy lifting capacity. The winch 5 is detachably installed on the top surface of the rear of the cuboid frame 11. The lifting rope 8 is connected to the winch 5. The winch 5 can be started and rotated in both directions to realize the winding and unwinding of the lifting rope 8.

[0028] Furthermore, the bottom of the crane frame 1 is equipped with frame support wheels 17, and the cuboid frame 11 is equipped with handles 18. The crane frame 1 can be moved on the ground manually by using the handles 18, which facilitates the transfer and handling of the crane frame 1.

[0029] Example 2, based on Example 1, provides a handling and hoisting tool for field operations without grid power, such as... Figure 3 , Figure 4 As shown, the crane chassis 2 includes a circular track 21, with a central shaft 24 positioned at the center of the circular track 21. The central shaft 24 is connected to the circular track 21 via chassis support rods 26. Frame support wheels 17 engage with the circular track 21. Multiple frame support wheels 17 are distributed at the front, middle, and rear positions of the bottom of the crane frame 1. The frame support wheels 17 located at the front and middle positions of the bottom of the crane frame 1 are arranged in a circular array. Each frame support wheel 17 is a caster wheel. After the crane frame 1 and crane chassis 2 are assembled, the circular track 21 engages with the frame support wheels 17, allowing the crane frame 1 to rotate around the central shaft 24, thus enabling the transfer and handling of hoisted items.

[0030] Furthermore, the rotary drive mechanism includes a rotary motor 15 and a gear disk 23. The rotary motor 15 is mounted on the crane frame 1, and the gear disk 23 is mounted on the central shaft 24 of the chassis. The output end of the rotary motor 15 is provided with a gear shaft 16, which meshes with the gear disk 23. When the rotary motor 15 is started, it drives the gear shaft 16 to rotate, and then the meshing of the gear shaft 16 with the gear disk 23 drives the crane frame 1 to rotate on the crane chassis 2. This eliminates the physical labor required for manual pushing, and can significantly reduce the workload, especially in scenarios with large counterweights, thus meeting the needs of both heavy lifting and labor-saving operation.

[0031] Furthermore, the power generation assembly includes a gasoline generator 6 and a distribution box 7. The gasoline generator 6 is located at the lower front part of the cuboid frame 11, and the distribution box 7 is located on the upper part of the central shaft outer sleeve 12. The distribution box 7 contains an electrical switch, an AC contactor, a frequency converter, and a gasoline generator voltage regulator. The frequency converter regulates the speed of the rotating motor 15, the AC contactor starts the rotating motor and the winch, and the generator voltage regulator enables the gasoline generator 6 to output a stable voltage. The gasoline generator 6 supplies power to the winch 5 and the rotating motor 15 through the distribution box 7. The rear part of the cuboid frame 11 is used to place a counterweight. A mesh is provided on the bottom rear surface of the cuboid frame 11 to facilitate the placement of the counterweight.

[0032] Furthermore, a support baffle 121 is provided inside the outer sleeve of the central shaft 12. A groove is provided on the lower side of the support baffle 121, and a steel ball 25 is provided at the upper end of the central shaft 24 of the chassis. The steel ball 25 cooperates with the groove. The groove is a semi-circular groove, which effectively reduces the friction between the top of the central shaft 24 of the chassis and the support baffle 121.

[0033] Furthermore, the bottom of the circular track 21 is provided with multiple chassis support wheels 22. Specifically, there are 7 chassis support wheels 22, which are evenly distributed at the bottom of the circular track 21; the chassis support wheels 22 are omnidirectional wheels, which facilitate the movement of the crane tools.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
