Figure 4 and Figure 5As shown, in the unlocked state, the operating body 61 is located at a first position that forms a certain angle with the vertical plane, the locking pin 641 is located at the upper end of the locking groove 632, and the elastic pressing portion 62 is in a natural state; when the operating body 61 is flipped from the first position to the vertical second position under the action of an external force, the locking pin 641 moves along the locking groove 632 to the lower end and is limited, entering the locked state; Figure 7 As shown, in the locked state, the elastic pressing portion 62 is compressed to press and lock the transmission chain 41.

[0125] The self-locking mechanism 60 can lock the transmission chain, and the lifting bucket 30 can be parked at any height, which is convenient for material transportation. By applying an external force to the operating body 61 of the self-locking mechanism 60, the operating body 61 is pushed from the first position to the second position.

[0145] In an optional embodiment, the support leg includes a shock absorbing mechanism.

[0146] The outriggers are equipped with shock-absorbing mechanisms to improve operational stability and reduce the impact of vibration on the conveying process.

[0147] The shovel hoist uses high-quality alloy steel as the main material to ensure its durability and stability in high-intensity working environments. The core part of the equipment is the lifting bucket 30, which adopts a streamlined design, which not only increases the material holding capacity, but also reduces the resistance during the lifting process. The connection between the lifting bucket 30 and the chain adopts a unique hinge design, and the hinge has an integrated self-locking function to ensure that it is not easy to accidentally slide down when the hoist is parked, thereby enhancing the safety of use. High-strength materials are specially selected to improve the bearing capacity of the hinge to meet the heavy load requirements in different environments. The locking mechanism can be unlocked by applying external force. Under the action of external force, the operating body 61 begins to move and prepares to leave the locking position. When the operating body 61 completely leaves the locking position, the locking pin is separated from the locking slot or hole. At this time, the hinge resumes the free rotation state and can be operated or adjusted accordingly.

[0148] The power system of the shovel hoist uses an energy-efficient motor and is equipped with an intelligent frequency converter. This system can not only adjust the speed according to the load changes to achieve energy-saving effects, but also provide smooth operating performance when starting and stopping to reduce equipment wear. In addition, the intelligent control system (no improvement in the control system) can monitor the operating status of the equipment in real time and adjust the parameters in time to ensure the safety and stability of the equipment.

[0149] In terms of safety design, we have considered various potential risks and equipped the equipment with multiple safety protection measures, including overload protection, emergency stop device and anti-misoperation design, to ensure that the equipment can be shut down quickly under abnormal conditions and avoid accidents under extreme conditions. At the same time, all contact parts of the elevator are specially treated with wear-resistant alloy layer to effectively prevent fire hazards caused by friction.

[0150] This shovel elevator has good adaptability in design and can be adjusted according to the characteristics of different materials and working environments. Its modular design enables the equipment to be flexibly customized according to user needs to meet the requirements of different locations.

[0151] Optimized bucket design: Streamlined bucket design is adopted to reduce digging resistance and improve digging efficiency. Wear-resistant alloy layer is set on the edge of bucket to enhance wear resistance and prolong service life. A baffle with adjustable material placement space is set inside the bucket. The first worm screw mechanism includes a rotating threaded cap, which is connected to a worm, which is meshed with a worm wheel, and a threaded hole is opened in the center of the worm wheel, and a threaded column is set in the threaded hole, such as Figure 1As shown, by rotating the threaded cap, the threaded column is driven to move up and down due to the transmission between the threaded cap and the threaded column. This movement drives the triangular adjustment block 14 to rotate, so that the slider of the translation assembly 13 moves along the slide rail, and the baffle installed on the slider moves, thereby adjusting the distance and space between the baffle and the bucket. Adjustment is made according to the shape and volume of the material to reduce the risk of material overflow and crushing.

[0152] Improvement of drive system: Adopt variable frequency speed regulating motor drive, automatically adjust the speed according to the load, and achieve energy saving and consumption reduction. Design double sprocket transmission system. The double sprocket transmission system of the hoist consists of several important components, and its input end is mainly connected to the motor. The motor transmits the rotational power to the double sprocket through the coupling, and directly drives the working mechanism of the hoist through the chain transmission, which enhances the transmission stability and reduces vibration and noise.

[0153] Introduce intelligent control system to monitor the operating status of the elevator in real time, realize fault warning and remote control.

[0154] Enhanced structural stability: Optimize the frame structure, use high-strength steel and reasonable welding technology - considering the material characteristics, structural complexity and production cost of the hoist frame, it is recommended to use a composite welding process (arc welding combined with MAG welding). This process can effectively control the heat-affected zone and reduce material deformation and stress concentration while ensuring welding strength. In addition, combined with modern welding equipment, it can improve welding efficiency and quality. Improve overall rigidity and stability.

[0155] Add shock-absorbing devices to reduce the impact and wear on the equipment during operation. Design retractable support legs to adapt to the height changes of different working surfaces and ensure the stable operation of the hoist. Figure 8 and Fig. 9 As shown, the handle 73 is turned to raise the supporting screw rod 72, thereby supporting the lifting machine to be lifted to a desired height.

[0156] Shovel lifts can be divided into the following main modules:

[0157] The lifting module, including the lifting bucket, lifting chain, etc., is responsible for the lifting and transportation of materials.

[0158] The drive module, including the motor, reducer, transmission device, etc., provides power support.

[0159] The control module, including control system, sensor, monitoring equipment, etc., realizes automatic control and monitoring of the elevator.

[0160] The base module, including equipment support structure, foundation, etc., ensures the stability of the elevator.

[0161] Technical effects of the present invention:

[0162] The lifting efficiency is significantly improved. Through the optimized bucket design, the excavation efficiency is increased by about 20%, and the overall lifting efficiency is significantly improved.

[0163] Energy consumption has been greatly reduced. The application of variable frequency speed regulating motors and intelligent control systems has reduced energy consumption by about 15%, achieving green production.

[0164] Reduce maintenance costs. The design of wear-resistant alloy layer, shock-absorbing device and high-strength structure prolongs the service life of the equipment and reduces the maintenance frequency and cost.

[0165] Reduce material breakage. The baffle design with adjustable angle effectively reduces the breakage rate of materials during the lifting process and improves material quality.

[0166] Enhanced operational stability, overall structure optimization and the use of shock-absorbing devices have improved the operational stability of the equipment and reduced the occurrence of failures.

[0167] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the present application.
