Description

Technical Field

[0001] The utility model belongs to the technical field of battery module hoisting, and specifically discloses a battery module hoisting device. Background Art

[0002] With the rapid development of new energy, the specifications and styles of battery modules are constantly diversified. Today's large battery modules are fixed with side beams and then lifted and moved to a designated position. This type of module hoist is a simple hoist for trial production, with high labor intensity, low efficiency and certain safety risks. When the battery module is put into the box, it is not easy to accurately position it, and it is difficult for the staff to lift the module when taking the hoist.

[0003] A battery module hoisting fixture with patent application number CN110386545B includes a hoisting assembly, a base plate, a guide mechanism, a clamping mechanism, two handles and two indexing pins; the hoisting assembly, handles and indexing pins are all arranged at the upper end of the base plate; the guide mechanism is arranged at the lower end of the base plate; the clamping mechanism is arranged at the upper end and the lower end of the base plate. The clamping mechanism of the above device is arranged at the upper end and the lower end of the base plate, which is prone to inaccurate positioning when clamping and positioning the battery module, and the above device is not provided with anti-insulation parts, which may cause accidents when hoisting the battery module. Therefore, it is urgent for those skilled in the art to solve the above technical problems. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a battery module lifting device in view of the deficiencies of the above-mentioned prior art. The battery module lifting device can accurately position the battery module through a clamping structure and ensure the stability of the clamping, and can adjust the distance between the clamping structures at both ends of the bottom of the bracket through a variable distance structure to improve the versatility of the device.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A battery module lifting device comprises a lifting ring, a hanging chain, a bracket, a handle, an operating button, a clamping structure, a variable distance structure and an electrical interface; the lifting ring is connected to the bracket through the hanging chain, the bracket is also provided with a handle, and the operating button is provided on the handle; the clamping structure is provided at both ends of the bottom of the bracket, the clamping structure is used for clamping the battery module, the variable distance structure is used for adjusting the distance between the clamping structures at both ends, and the variable distance structure is provided at the bottom of the bracket; the electrical interface is provided above the bracket.

[0007] Furthermore, the clamping structure includes a first clamping cylinder, a second clamping cylinder, a first clamping cylinder solenoid valve, a second clamping cylinder solenoid valve, a clamping jaw, a clamping jaw protection unit, a clamping jaw detection unit and a clamping jaw slider; the first clamping cylinder is arranged at the left end of the bottom of the bracket, and two first clamping cylinder solenoid valves are arranged on the first clamping cylinder; the second clamping cylinder is arranged at the right end of the bottom of the bracket, and two second clamping cylinder solenoid valves are arranged on the second clamping cylinder; the two ends of the first clamping cylinder are connected to the two clamping jaws through the clamping jaw slider, and the two ends of the second clamping cylinder are connected to the two clamping jaws through the clamping jaw slider; the clamping jaw protection unit is used to protect the clamping jaw, the clamping jaw protection unit is welded to the bracket, and the clamping jaw is arranged in the clamping jaw protection unit; the clamping jaw detection unit is used to detect whether the clamping jaw is clamped, and the clamping jaw protection unit is arranged on the inner side of the clamping structure.

[0008] The first and second clamping cylinders are each equipped with a solenoid valve to achieve the function of independent control of the clamps on both sides, which not only improves the accuracy of the clamping module, but also ensures through a double insurance mechanism that even if one side of the cylinder fails, the other side can still maintain the stability of the module, thereby increasing safety. The clamp is connected to the cylinder through a clamp slider, so that the clamp can slide along the guide rail under the push of the cylinder to achieve dynamic adaptation to modules of different widths. This design improves the versatility of the spreader and can be applied to modules of various sizes, reducing changeover time and cost. The setting of the clamp protection unit effectively prevents accidental injuries or module damage that may be caused by the exposure of the clamp in the non-working state. By retracting the clamp into the protection unit, the risk of collision caused by misoperation can be avoided regardless of the posture of the spreader, thereby ensuring the safety of the module and equipment: the addition of the clamp detection unit can monitor the working status of the clamp in real time, ensuring that the module is clamped firmly before the next step is taken, thereby avoiding the module from slipping or falling due to lifting without clamping. The intelligent monitoring of this sensor greatly improves the reliability and safety of the operation.

[0009] Furthermore, the clamping jaw detection unit is made of a sensor, and a plurality of the clamping jaw detection units are provided.

[0010] The arrangement of multiple sensors can monitor the closing state of the clamping jaws from multiple angles or positions to ensure the comprehensive and accurate clamping action. Even if a sensor fails or misjudges, other sensors can still provide reliable information to prevent the module from being lifted without clamping, reducing the risk of the module falling. Multi-point detection can more accurately determine the tightness of the contact between the clamping jaws and the module. Through multi-data mutual verification, the accuracy of judgment is improved, false alarms or missed alarms are reduced, making the entire lifting process more reliable and avoiding operational errors caused by inaccurate detection. During operation, once the sensor detects that the clamping is not in place, it can immediately feedback to the control system, and the operator can make timely adjustments to avoid invalid or dangerous actions, improve work efficiency, and reduce downtime adjustment time. Although the multi-sensor configuration increases the complexity of the system, it also disperses the risk of failure. Even if a single sensor is damaged, the system can still maintain basic functions, which is convenient for maintenance or replacement without stopping production, reducing the impact on production continuity.

[0011] Furthermore, the variable pitch structure includes a variable pitch cylinder, a variable pitch cylinder solenoid valve, a variable pitch slider, a front limit seat and a rear limit seat; the variable pitch cylinder is arranged at the bottom of the bracket, the variable pitch cylinder solenoid valve is arranged on the variable pitch cylinder, the variable pitch cylinder is connected to the clamping structure through the variable pitch slider, and the front limit seat and the rear limit seat are arranged at the bottom of the bracket.

[0012] The combination of the variable pitch cylinder and the solenoid valve enables the clamping mechanism to be quickly adjusted according to the different sizes of the module, that is, the position of the slider is changed by the extension and contraction of the cylinder, and then the distance between the two sets of clamps is adjusted to meet the gripping requirements of modules of different lengths and widths. This greatly improves the compatibility and flexibility of the equipment for modules of various specifications on the production line, reduces the changeover time, and improves production efficiency. The setting of the front limit seat and the rear limit seat provides a clear travel end point for the telescopic movement of the variable pitch cylinder, ensuring the accuracy and consistency of the variable pitch adjustment. These limit seats avoid over-extension or under-displacement, making each adjustment accurate and in place, ensuring the stability and safety of the clamping module. The telescopic action of the variable pitch cylinder can be achieved by the operator controlling the solenoid valve, without the need for complicated staff adjustments, simplifying the operating process, reducing the difficulty of operation, reducing the risk of misoperation caused by staff intervention, and improving work efficiency. The variable pitch structure is integrated at the bottom of the bracket and is tightly combined with the overall frame. This design enhances the overall stability, ensures the smoothness of the variable pitch operation, and will not affect the overall balance of the sling, further improving the safety of the operation and the stability of the module during transportation. The integrated design facilitates daily inspection and maintenance, and key components such as the variable pitch cylinder and solenoid valve are easy to access. When repair or replacement is required, the problem can be quickly located, reducing downtime and reducing the impact on production.

[0013] Furthermore, the operating button is electrically connected to the clamping structure and the variable distance structure.

[0014] The operator only needs to control the clamping cylinder to clamp and release the module and the variable pitch cylinder to adjust the spacing through the operation button. There is no need to operate each mechanical component separately, which greatly simplifies the operation process, reduces the complexity of operation, and improves work efficiency. The electrical connection enables all actions to be performed synchronously or in a predetermined order. For example, clamping is performed first and then adjusting the spacing, or vice versa. This ensures the coordination and safety between actions and avoids potential risks caused by incorrect operation sequence. The centralized control logic can preset safety logic, such as lifting is not allowed if it is not clamped, and clamping is not allowed if the spacing is not appropriate. In this way, the safety of the operation process is ensured through the electronic control logic, and the risk of accidents caused by staff misoperation is reduced. The electronic control system is easy to diagnose and maintain. Once a fault occurs, the problem can be quickly located through system detection for easy repair. At the same time, the electronic control system also provides possibilities for future technology upgrades, such as access to automated control systems, remote control or intelligent improvements.

[0015] Furthermore, a plurality of insulating pads are arranged at the bottom of the bracket, the insulating pads are made of polyurethane, and the insulating pads are arranged at the bottom of the clamping structure.

[0016] Polyurethane material has good electrical insulation properties and can effectively prevent electrical short circuits caused by accidental contact during the lifting process, protect the positive and negative poles of the module from being accidentally touched, thereby protecting the module from electrical damage and ensuring electrical safety. Polyurethane soft blocks have excellent elasticity. As a buffer material, they can absorb impact force, reduce vibration and collision, and protect the module from physical damage during the placement or movement of the module. This is especially important for the protection of precision electronic components to avoid internal damage caused by vibration. Polyurethane material has good wear resistance and is not easy to wear after long-term use, which ensures the stability and service life of the sling, reduces maintenance costs, and also reduces the frequency of replacement, ensuring the continuity and reliability of the lifting operation. Polyurethane soft blocks can also provide a certain amount of friction to prevent the module from sliding on the sling, especially when the sling is adjusted or subjected to external force, to ensure the stable positioning of the module, reduce the risk of dislocation, and improve the accuracy of the operation.

[0017] The utility model has the following beneficial effects:

[0018] 1. The built-in sensor monitoring of the clamping structure ensures that the battery module is fully clamped before it is allowed to be lifted, which effectively prevents the risk of the module falling due to lifting without clamping. The pneumatically driven clamping structure can easily control the clamping and loosening of the battery module through the operation button, reducing the labor intensity and potential errors of the staff, improving work efficiency, and also reducing the safety risks caused by human factors;

[0019] 2. The introduction of the variable distance structure enables the hoist to quickly adjust the spacing of the clamping structure according to the different battery module sizes to meet the grabbing requirements of different types of battery modules, greatly improving production flexibility and efficiency, and further improving the response speed of the production line. The entire hoist adopts a frame structure design to enhance stability and ensure that the module will not shake or fall during the lifting process;

[0020] 3. A plurality of insulating pads made of polyurethane soft blocks are arranged at the bottom of the bracket, which reduces the possibility of accidents caused by short circuits during the connection of the clamping structure to the battery module. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] When in use, the staff moves the hoist to the top of the module through the handle 2, and lowers the battery module hoisting device to the battery module to be hoisted through the control button 3 on the handle 2. At this time, the battery module hoisting device descends, and the battery module hoisting device aligns the battery module to be grasped position through the clamping claw 43 on the clamping mechanism 4.
