TECHNICAL FIELD

[0001] The utility model relates to a kind of lifting appliance, more specifically to a simple battery hoisting and moving mechanism for battery swap station. BACKGROUND

[0002] In the field of electric trucks, due to the longer charging time caused by the more batteries equipped, the batteries are usually fixed on a support frame to form a battery pack that can be replaced as a whole, and a battery swap station is provided for charging the battery pack. When the battery pack on the vehicle is insufficient, the vehicle can be driven to the battery swap station for battery pack replacement to avoid affecting the normal use of the vehicle. Because the battery pack is heavy, the battery pack is usually lifted and transported by a row of cranes and a matching lifting appliance. The conventional lifting appliance has the problems of inconvenient connection and low automation, such as the patent with the announcement number CN215946488U disclosed as "a new energy vehicle power battery lifting appliance". To solve the problems of the conventional lifting appliance, the technical personnel in the field have developed a lifting system that connects the battery pack automatically through electric control, such as the patent with the publication number CN116119539A disclosed as "a truck battery swap station battery lifting system", which includes a row of cranes and a lifting appliance. The row of cranes includes a longitudinal moving frame and a transverse moving frame, as well as a lifting mechanism installed on the transverse moving frame and composed of a speed reducer, four fixed pulleys, and four steel wires. The lifting appliance includes a support frame, four movable pulleys, and four hook assemblies. The four movable pulleys are connected by corresponding four steel wires, and the four hook assemblies are controlled by front and rear two groups of driving mechanisms. This structure of the battery lifting system has the problems of complex structure, large space occupation, and poor stability because the speed reducer and the fixed pulleys are arranged on the transverse moving frame of the row of cranes, and the movable pulleys are arranged on the support frame of the lifting appliance.

Both sides of the driving sprockets are respectively provided with driven sprockets installed on the transverse moving frame. Four fixed pulleys are symmetrically distributed on the transverse moving frame.

[0005] Further, the utility model provides a simple battery hoisting horizontal moving mechanism, wherein, the horizontal moving roller is single side steel rail wheel, the longitudinal both sides of horizontal moving frame are equipped with two longitudinal limiting components which are distributed in horizontal direction, and longitudinal limiting component includes adapter support which is fixed on horizontal moving frame through bolt, limiting roller which is in horizontal state is installed on adapter support, and limiting roller is rolling bearing.

[0010] Compared with the prior art, this utility model of a simple battery hoisting and traversing mechanism has the following advantages: This utility model sets up a traversing frame, installs traversing rollers at the four corners of the traversing frame, and fixes a reducer in the middle of the traversing frame. The input shaft of the reducer is connected to a motor, and the two ends of the output shaft of the reducer are respectively installed with drive sprockets on the longitudinal outer side of the traversing frame through transmission shafts. Driven sprockets are respectively installed on the transverse sides of the drive sprockets on the traversing frame, and four fixed pulleys are installed on the traversing frame in a symmetrical distribution. Thus, a simple battery hoisting and traversing mechanism with simple structure, convenient operation, stability and reliability and strong practicality is formed. In practical applications, the lateral movement mechanism is placed on a transverse guide rail on the longitudinal movement frame of the gantry crane via lateral movement rollers. Two chains with fixed ends are installed on the longitudinal movement frame of the gantry crane, and the two chains are arranged in a V-shape to pass over the corresponding driving and driven sprockets. This completes the installation of the lateral movement mechanism on the longitudinal movement frame of the gantry crane. When the motor and reducer drive the driving sprocket to rotate through the drive shaft, the lateral movement mechanism moves along the transverse guide rail with the help of the chains.

The rope winding pulley is fixed to the output shaft of the corresponding reducer. When the battery hoist releases the wire ropes through the reducer and rope winding pulleys, the battery hoist descends due to the extension of the wire ropes. When the battery hoist retracts the wire ropes through the reducer and rope winding pulleys, the battery hoist ascends due to the shortening of the wire ropes. Compared with the prior art, this utility model simplifies the structure by removing the lifting reducer and rope winding pulley originally located on the horizontal moving frame and installing the four fixed pulleys at the upper and lower middle positions of the horizontal moving frame. This reduces the overall height and space occupied by the horizontal moving mechanism and the battery hoist. Furthermore, this utility model improves drive reliability and control precision by using a sprocket and chain drive, with the chain winding around the driving sprocket and two driven sprockets in a V-shape, compared with the prior art that directly drives the steel wheels.

[0016] First, it should be noted that the directional terms such as up, down, left, right, front, and back mentioned in this utility model are only descriptions based on the accompanying drawings for ease of understanding, and are not intended to limit the technical solution or the scope of protection claimed in this utility model.

[0017] like Figures 1 to 4 The present invention provides a specific embodiment of a simple battery hoisting and traversing mechanism, which includes a traversing frame 1, traversing rollers 2 installed at the four corners of the traversing frame 1, and a reducer 3 fixed in the middle of the traversing frame 1. The input shaft of the reducer 3 is connected to a motor (not shown in the figure), and the output shaft of the reducer 3 is connected to two drive sprockets 5 located on the longitudinal outer side of the traversing frame 1 via a transmission shaft 4. Driven sprockets 6 are installed on the traversing frame 1 on both sides of the drive sprockets 5, and four fixed pulleys 7 are symmetrically distributed on the traversing frame 1.

[0018] The above setup constitutes a simple, easy-to-operate, stable, reliable, and highly practical battery lifting and traversing mechanism. In practical applications, the traversing mechanism is placed on a transverse guide rail on the longitudinal traversing frame of the gantry crane via traversing rollers 2. Two chains with fixed ends are installed on the longitudinal traversing frame of the gantry crane, and the two chains are arranged in a V-shape to pass over the corresponding driving sprocket 5 and driven sprocket 6. This completes the installation of the traversing mechanism on the longitudinal traversing frame of the gantry crane. When the motor and reducer 3 drive the driving sprocket 5 to rotate through the transmission shaft 4, the traversing mechanism moves along the transverse guide rail with the help of the chains. When the traversing mechanism is connected to the battery lifting device, the battery... The four wire ropes of the lifting device are routed around four fixed pulleys 7. One end of each wire rope is fixed to the docking frame of the battery lifting device, and the other end is fixed to a corresponding rope winding pulley on the docking frame. The rope winding pulley is fixed to the output shaft of the corresponding reducer. When the battery lifting device releases the wire ropes through the reducer and the rope winding pulley, the battery lifting device will descend due to the extension of the wire ropes. When the battery lifting device retracts the wire ropes through the reducer and the rope winding pulley, the battery lifting device will ascend due to the shortening of the wire ropes. Compared with the prior art, this utility model simplifies the structure by removing the lifting reducer and rope winding wheel originally set on the transverse frame and installing four fixed pulleys 7 at the upper and lower middle positions of the transverse frame. This helps to reduce the overall height and space occupied by the transverse mechanism and the combination with the battery hoist. At the same time, this utility model improves the drive reliability and control accuracy by adopting a sprocket and chain drive form and making the chain pass around the driving sprocket 5 and two driven sprockets 6 in a Z-shape, compared with the prior art of directly driving the steel wheel to roll.

[0019] In a specific implementation, this invention employs a single-sided steel rail wheel structure for the transverse roller 2 to improve structural and movement stability. Two longitudinal limiting components 8, spaced apart laterally, are respectively installed on both sides of the transverse frame 1 to prevent the transverse mechanism from deviating. The longitudinal limiting component 8 includes a transition support 81 and a limiting roller 82 mounted horizontally on the transition support 81. The transition support 81 is bolted to the transverse frame 1, and the limiting roller 82 is a rolling bearing. This configuration of the longitudinal limiting component 8 features a simple structure, low cost, and stable reliability. When the transverse mechanism moves along the transverse guide rail on the gantry crane's longitudinal frame, the limiting rollers 82 of each longitudinal limiting component 8 are pressed against the gantry crane's longitudinal frame. In a specific embodiment, for ease of detection and control, this utility model installs a proximity switch 11 and two limit switches 12 on the transverse frame 1 via adapter brackets. The proximity switch 11 detects the position of the transverse frame 1, and the limit switches 12 detect the movement distance of the transverse frame 1. The longitudinal frame of the gantry crane is equipped with a detection plate that cooperates with the proximity switch 11 and the limit switches 12. To prevent the transverse mechanism from exceeding its movement range, this embodiment fixes baffles 13 on both sides of the transverse frame 1, and rubber buffer pads 14 are fixed on the baffles 13. The longitudinal frame of the gantry crane is equipped with limiting components that cooperate with the baffles 13 and the buffer pads 14. During use, to achieve stable docking with the battery hoist, this embodiment fixes two positioning cylinders 15 at the bottom of the transverse frame 1, and the lower end of the positioning cylinders 15 adopts a flared structure. The docking frame of the battery hoist is equipped with positioning posts that cooperate with the positioning cylinders 15.

This configuration features simple structure, convenient assembly and disassembly, and stable reliability. Similarly, in this specific embodiment, the drive shaft 4 is mounted on the transverse frame 1 via the second bearing seat 17, and the driving sprocket 5 is fixed to the drive shaft 4. In a specific embodiment, the present invention employs the following installation method for the driven sprocket 6: the driven sprocket 6 is mounted on the first support shaft via a bearing, and the first support shaft is fixed to the transverse frame 1 via a mounting seat 61. This configuration of the driven sprocket 6 also features simple structure, convenient assembly and disassembly, and stable reliability. Similarly, this utility model employs the following installation method for the fixed pulley 7: the fixed pulley 7 is mounted on the second support shaft via bearings, the second support shafts on both sides of the fixed pulley 7 are respectively fixed to the transverse frame 1, and bracket plates 18 fixed to the transverse frame 1 are respectively provided on both sides of the fixed pulley 7. Support rods distributed along the upper half-circumference of the fixed pulley 7 are provided between the bracket plates 18, and rollers 19 are sleeved on the support rods. This arrangement, through the support rods and rollers 19 distributed along the upper half-circumference of the fixed pulley 7, can effectively block and limit the steel wire rope connected to the fixed pulley 7, thereby improving stability.
