Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary equipment for battery swapping stations of electric vehicles, in particular to a gantry crane convenient for transportation. Background Technique

[0002] At present, new energy vehicles are developing rapidly, and there are many types of them. Among them, electric special engineering vehicles have been widely used in the fields of engineering and construction. The power source of pure electric special engineering vehicles is a power storage battery. The power storage capacity of the power storage battery will decline during long-term use and needs to be replaced. The battery swapping method for the power storage battery is: replacing the fully charged battery from the battery swapping station, removing the discharged battery, and charging it at the battery swapping station, which improves the endurance efficiency of electric special engineering vehicles.

[0003] Most of the existing charging stations use a hoisting method to disassemble or install the battery. The hoisting device is generally located above the battery storage area and the driving lane, and is used to hoist the fully charged battery in the battery storage area onto the battery swapping vehicle in the driving lane. The existing hoisting device generally includes support vertical frames on both sides. A crossbeam guide rail for sliding the support sling is erected on the top of the vertical frames. The discharged battery is clamped out by the sling, and the fully charged battery is hoisted onto the electric vehicle for battery swapping operation. However, when the existing hoisting device is installed, the support vertical beams, crossbeam guide rails, slings, etc. need to be transported to the site for assembly and installation first. Since the support vertical frames are relatively high, they occupy a large area during transportation and are not convenient for transportation. There is also a method of disassembling each support vertical beam into multiple parts, transporting them to the site and then splicing and welding them, which increases the installation difficulty on site. Content of the Utility Model

The length direction of each lower slide rail is parallel to the length direction of the battery swapping channel. Rollers for slidably connecting with the lower slide rails are arranged at the bottom of the sliding support.

[0010] Among them, the bottom end of the pillar of the sliding support is fixedly connected to a horizontal strip-shaped bottom beam. The roller is rotatably connected to the bottom beam. End plates are arranged at the axial two ends of the bottom beam, and sliding grooves for cooperating with the lower slide rails are opened at the bottom ends of the end plates.

[0011] Among them, each of the support chassis includes a horizontally arranged longitudinal beam and multiple main legs arranged at the bottom of the longitudinal beam. The multiple main legs are parallel and vertically arranged, and the multiple main legs are arranged along the axial direction of the longitudinal beam.

[0027] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Many specific details are set forth in the following description in order to fully understand the present utility model, but the present utility model may also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0028] As Figure 1 , Figure 2 , Figure 4 shown, a gantry crane convenient for transportation includes a support chassis 1, a sliding support 2, and a lifting appliance 3. The number of the support chassis 1 is two, and the two support chassis 1 are arranged oppositely. A power exchange passage 4 for accommodating an electric vehicle to pass through and perform power exchange is formed between the two support chassis 1. The sliding support 2 is slidably connected between the two support chassis 1. The sliding direction of the sliding support 2 is parallel to the axial direction of the power exchange passage 4. The sliding support 2 is in a gantry structure, and both sides in the length direction of the sliding support 2 are slidably connected to the upper parts of the corresponding support chassis 1 on the corresponding side. The lifting appliance 3 is slidably connected to the sliding support 2, and the sliding direction of the lifting appliance 3 slides along the length direction of the sliding support 2. The sliding support 2 and the support chassis 1 together form the overall structure of the gantry crane. Before being transported to the site, two support chassis 1 and the sliding support 2 can be prefabricated first. During transportation, referring to Figure 5 , the two support chassis 1 can be respectively placed on both sides of the carriage of the transport vehicle, and the sliding support 2 and the lifting appliance 3 are placed between the two support chassis 1. Only one carriage is needed to transport the parts required for the gantry crane, which is convenient for transportation. When assembling on site, only the two support chassis 1 need to be placed at the designated positions and arranged oppositely, and the support chassis 1 is fixedly installed on the ground at the site through bolts or the like. Then, the sliding support 2 is lapped and installed between the two support chassis 1, and finally the lifting appliance 3 is installed on the sliding support 2. The on-site installation operation is relatively simple, improving the installation efficiency. Through the split structure of the sliding support 2 and the support chassis 1, it is not only convenient for transportation but also can reduce the on-site installation difficulty and improve the on-site installation efficiency.

[0029] As Figure 1As shown in the figure, the sliding support 2 includes a horizontal sliding frame 21 and struts 22 fixedly arranged on both sides of the sliding frame 21. The sliding frame 21 has a rectangular frame structure, and one or more groups of upper sliding rails 23 are fixedly arranged inside the sliding frame 21. The number of groups of the upper sliding rails 23 can be set according to the requirements and scale of the battery swapping station. In this embodiment, the number of the upper sliding rails 23 is two groups, and the two groups of upper sliding rails 23 are arranged in parallel. The number of each group of upper sliding rails 23 is two, and the two upper sliding rails 23 are arranged in parallel and opposite to each other. The upper sliding rails 23 are fixedly installed on the sliding frame 21 by bolts. The axial direction (i.e., the length direction) of the upper sliding rails 23 is parallel to the long side of the sliding frame 21, and the long side of the sliding frame 21 is perpendicular to the length direction of the battery swapping channel (i.e., the length direction of the support chassis 1). In this way, during transportation, the sliding support 2 is placed in the space between two parallel support chassis 1. The width direction of the sliding support 2 (i.e., the width direction of the sliding frame 21) is perpendicular to the length direction of the support chassis 1, so that the sliding support 2 can be accommodated between the two support chassis 1, which is convenient for storage on the carriage. Each group of upper sliding rails 23 corresponds to a spreader 3, and the spreader 3 is slidably connected to the corresponding group of upper sliding rails 23, that is, both sides of each spreader 3 are respectively slidably connected to the corresponding side of the upper sliding rails 23 in the same group. The number of the struts 22 is multiple, and the number of the struts 22 is an even number. The multiple struts 22 are evenly divided into two groups, and the two groups of struts 22 are respectively fixedly arranged on both sides in the length direction of the sliding frame 21. Observed from the front or rear side of the battery swapping channel 4, the sliding support 2 has a portal structure, and the spreader 3 and some other tools, components, etc. can be placed in the space below the sliding support 2. In this embodiment, the number of each group of struts 22 is two, and the two struts 22 in the same group are located at both ends of the corresponding side of the sliding frame 21. The overall structure presented is that the total number of the struts 22 is 4, and the 4 struts 22 are located at the bottom ends of the four corners of the sliding frame 21. Refer to Figure 2 , Figure 3, the bottom end of the support column 22 of the sliding support 2 is fixedly connected to a horizontal strip-shaped bottom beam 24. The roller 25 is rotatably connected to the bottom beam 24. End plates 26 are arranged at both axial ends of the bottom beam 24. A chute 27 for cooperating with the lower slide rail is opened at the bottom end of the end plate 26. The setting of the chute 27, on the one hand, facilitates quickly positioning the sliding support 2 on the support chassis 1 during installation, and on the other hand, can further ensure the stable sliding of the sliding support 2 on the support chassis 1. In this embodiment, the number of bottom beams 24 is 2. The two bottom beams 24 are respectively located on both sides of the length direction of the sliding frame 21. The upper parts of both axial ends of each bottom beam 24 are fixedly connected to the corresponding side support columns 22, and the lower parts of both axial ends of each bottom beam 24 are respectively rotatably connected to the rollers 25. In this embodiment, one of the rollers 25 on each bottom beam 24 is a driving wheel, and this roller 25 is driven by a motor 28. The motor shaft of this motor 28 is fixedly connected to the central axis of the roller 25 through a right-angle shaft motor. By driving the roller 25 to rotate through the motor 28, the sliding support 24 is further driven to move on the support chassis 1. In the present utility model, the connection structure between the motor 28 and the roller 25 belongs to the conventional technology in the field and is not an improvement point of the present utility model. The sliding support 2 moves on the support chassis 1, and the position of the sliding support 2 in the length direction of the support chassis 1 can be adjusted according to the on-site space arrangement, making its position adjustment relatively flexible and capable of adapting to on-site installations with different space layouts. In addition, during battery swapping, if the parking position of the electric vehicle to be battery-swapped is not good, the position of the spreader 3 can also be adjusted by moving the sliding support 2 so that the spreader 3 can move to directly above the battery to be swapped of the electric vehicle to be battery-swapped.

[0030] A lower slide rail 11 is fixedly arranged on the upper part of each support chassis 1. The lower slide rails 11 on the two support chassis 1 are arranged in parallel and opposite to each other. The length direction of each lower slide rail 11 is parallel to the length direction of the battery swapping channel 4. The axial direction of the lower slide rail 11 is horizontal and perpendicular to the axial direction of the upper slide rail 23. The rollers 25 at the bottom of the sliding support 2 are slidably connected to the lower slide rail 11. Each support chassis 1 includes a horizontally arranged longitudinal beam 12 and a plurality of main legs 13 arranged at the bottom of the longitudinal beam 12. The lower slide rail 11 is fixedly arranged on the top surface of the longitudinal beam 12. The axial direction of the lower slide rail 11 is parallel to the axial direction of the longitudinal beam 12. The plurality of main legs 13 are arranged in parallel and vertically, that is, the plurality of main legs 13 are parallel to each other, and each main leg 13 is vertically arranged. The plurality of main legs 13 are arranged along the axial direction of the longitudinal beam 12. The support chassis 1 further includes a plurality of groups of reinforcing rods 15. The number of groups of the reinforcing rods 15 is the same as and corresponds to the number of the main legs 13. The number of each group of the reinforcing rods 15 is at least one. The reinforcing rods 15 are fixedly connected between the main legs 13 and the longitudinal beam 12. In this embodiment, the number of each group of the reinforcing rods 15 is two, and the two reinforcing rods 15 are arranged on both sides of the main leg 13. The reinforcing rods 15 are obliquely arranged. The top end of the reinforcing rod 15 is fixedly connected to the longitudinal beam 12, and the bottom end of the reinforcing rod 15 is fixedly connected to the main leg 13. The reinforcing rods 15, the main legs 13, and the longitudinal beam 12 enclose a triangle. The arrangement of the reinforcing rods 15 enhances the supporting force for the longitudinal beam 12, and further increases the bearing capacity of the sliding support 2. In order to reduce the weight of the device under the condition of sufficient bearing capacity, in this embodiment, the main legs 13 on both axial sides of the longitudinal beam 12 are side main legs, and the remaining main legs 13 are middle main legs. The lengths of the reinforcing rods 15 on both sides of the side main legs are inconsistent. In this embodiment, on one side of the side main leg close to the free end of the longitudinal beam 12, and the other side is the inner side of the side main leg. The length of the reinforcing rod 15 on the outer side of the side main leg is less than the length of the reinforcing rod on the inner side of the side main leg. The top end of the reinforcing rod 15 on the outer side of the side main leg is fixedly connected to the longitudinal beam 12, and the bottom end of this reinforcing rod 15 is fixedly connected to the middle part of the axial direction of the main leg 13. The top end of the reinforcing rod 15 on the inner side of the side main leg is fixedly connected to the longitudinal beam 12, and the bottom end of this reinforcing rod 15 is fixedly connected to the bottom end of the main leg 13. The arrangement of the reinforcing rods 15 of the middle main legs is the same as that of the reinforcing rods 15 on the inner side of the side main legs, that is, the top end of the reinforcing rod 15 is fixedly connected to the longitudinal beam 12, and the bottom end of this reinforcing rod 15 is fixedly connected to the bottom end of the main leg 13.

[0031] As Figure 2As shown in the figure, the support chassis 1 further includes auxiliary legs 14. The number of the auxiliary legs 14 is the same as and corresponds one by one to the number of the main legs 13. The upper part of the auxiliary leg 14 is fixedly connected to the upper part of the main leg 13. The bottom end of the auxiliary leg 14 is flush with the bottom end of the main leg 13, and an acute angle is formed between the auxiliary leg 14 and the main leg 13. The setting of the auxiliary legs 14 can further increase the supporting force of the main legs 13. The bottom end of the main leg 13 is fixedly provided with a mounting plate 16 for fixedly connecting with the ground, and the bottom end of the auxiliary leg 14 is also fixedly provided with a mounting plate 16 for fixedly connecting with the ground. When the main leg 13 and the auxiliary leg 14 are installed, the mounting plate 16 is fixed to the ground on site by bolts, which increases the stability of the entire gantry crane device.

[0032] When the utility model is transported, the two support chassis 1 can be respectively placed on both sides of the carriage of the transport vehicle, and the sliding bracket 2 and the lifting appliance 3 are placed between the two support chassis 1. Only one carriage is needed to transport the parts required for the gantry crane, which is convenient for transportation. Figure 5 This is the placement state of the gantry crane structure during transportation of the utility model.

[0033] When assembling on site after transportation, only need to place the two support chassis 1 at the designated positions and set them opposite to each other, fixedly install the support chassis 1 to the ground on site through bolts, etc., then lap and install the sliding bracket 2 between the two support chassis 1, and finally install the lifting appliance 3 on the sliding bracket 2. The on-site installation operation is relatively simple, which improves the installation efficiency. Through the split structure of the sliding bracket 2 and the support chassis 1, it is not only convenient for transportation, but also can reduce the on-site installation difficulty and improve the on-site installation efficiency.

[0034] As Figure 4 As shown in the figure, when the utility model is installed and put into use, first, the battery transport vehicle 5 transports the fully charged battery to one side in the width direction of the battery swapping channel 4. Wait for the battery swapping vehicle 6 to be driven by the driver to the designated position on the other side in the width direction of the battery swapping channel 4. The discharged battery is clamped to the battery collection place through the lifting appliance 3, and then the lifting appliance 3 slides above the battery transport vehicle 5 so that the upper slide rail 23 where the lifting appliance 3 is located is directly above the fully charged battery. The fully charged battery is taken out through the lifting appliance 3, and then slides to directly above the battery installation place of the battery swapping vehicle. The fully charged battery is hoisted to the battery installation place of the battery swapping vehicle 6 through the lifting appliance. The utility model can adjust the position of the lifting appliance or the vehicle in three ways: adjusting the position of the sliding bracket 2, the driver driving the battery transport vehicle 5, or the driver driving the battery swapping vehicle 6, so that the lifting appliance can smoothly pick up the fully charged battery or the discharged battery. In addition, the lifting appliance 3 in the utility model adopts the common lifting appliance of the existing battery swapping station, which is not the innovation point of the utility model.
