As shown in fig. 1, in order to achieve the above object, in one aspect, the present invention provides a hoisting device, including a framework 100 and a plug pin assembly 200 fixed on the framework 100 and used for being placed inside a vertical long hole, where the plug pin assembly 200 includes a pin rod 210, a diameter-changing mechanism sleeved outside the pin rod 210, and an elastic force-applying mechanism installed on the framework 100 and used for applying force to the diameter-changing mechanism to change the diameter of the diameter-changing mechanism; reducing mechanism sets up to make bolt subassembly 200 puts into behind the vertical slot hole site, through elasticity forcing mechanism applied force and diameter increase, can block in the vertical slot hole site and keep the state of blocking, promptly: the latch assembly 200 is self-locking within the vertical slot hole location. Specifically, the diameter changing mechanism includes a first wedge sleeve 220 and a second wedge sleeve 230 that fit over the pin 210. As shown in fig. 2 and 3, one end of the pin rod 210 is fixed on the framework 100, and the other end is a free end; the first wedge sleeve 220 and the second wedge sleeve 230 respectively comprise a wedge end 202 with an inclined surface, the first wedge sleeve 220 and the second wedge sleeve 230 are respectively sleeved on the pin rod 210 from bottom to top, the wedge ends 202 of the first wedge sleeve 220 and the second wedge sleeve 230 are arranged oppositely, so that the first wedge sleeve 220 and the second wedge sleeve 230 can be attached and slide along the inclined surfaces of the wedge ends 202 of each other, and the diameter size of a cylindrical surface formed by combining the first wedge sleeve 220 and the second wedge sleeve 230 is changed. The elastic force application mechanism comprises an upper pulling handle 300 and a spring 400, wherein the spring 400 and the upper pulling handle 300 are sequentially sleeved on the pin rod 210 from top to bottom, and the spring 400 is positioned between the upper pulling handle 300 and the framework 100. The first wedge-shaped sleeve 220 and the second wedge-shaped sleeve 230 also have a flat end 201 opposite to the wedge-shaped end 202 thereof, and for positioning convenience, the flat end 201 of the second wedge-shaped sleeve 230 is provided with a limiting ring 231 for limiting and fixing with the pull-up handle 300. In order to ensure that the hoisted object is uniformly stressed in the hoisting process, the number of the bolt assemblies 200 is multiple, the bolt assemblies correspond to the number and the positions of the vertical long hole positions arranged on the hoisted object, and the bolt assemblies 200 are arranged around the framework 100. Specifically, in the embodiment shown in fig. 1, the number of the latch assemblies 200 is four, and the four latch assemblies are respectively located at four top corners of a rectangular plane formed by the framework 100, and accordingly, the number of the pull-up handles 300 is two, and each pull-up handle 300 is connected between the latch assemblies 200 located at the top corners of the short sides of the rectangle. For convenience in hoisting, a handle 110 is further disposed at the top of the center of the framework 100, and during hoisting, external hoisting force can be directly applied to the handle 110.
The operation principle of the present invention will be described in detail below with reference to fig. 2 and 3, and the operation process of the present invention. Specifically, the working process of the hoisting device provided by the invention is as follows:
firstly, the lifting handles 300 arranged at two sides of the hoisting device are pulled upwards, so that the spring 400 is contracted, and the second wedge-shaped sleeve 230 is driven by the lifting handles 300 to ascend; secondly, aligning the four bolt assemblies 200 inside vertical long hole positions on the hoisted object; subsequently, the upper pull handle 300 is released, so that the spring 400 is naturally extended, and the spring 400 drives the second wedge-shaped sleeve 230 to move downwards; finally, the lifting device is lifted by the handle 110, and the first wedge-shaped sleeve 220 is in contact with the inclined end face of the second wedge-shaped sleeve 230 and slides relatively to the inclined end face of the second wedge-shaped sleeve, so that module lifting is realized. More specifically, if the object to be hoisted is to be hoisted, the external lifting force F is greater than the gravity G of the object to be hoisted, the relative position of the second wedge-shaped sleeve 230 is kept unchanged by the elastic force F exerted by the spring 400 on the second wedge-shaped sleeve 230, and the first wedge-shaped sleeve 220 moves upwards relative to the second wedge-shaped sleeve 230, so that the diameter D of the cylindrical surface formed by the combination of the first wedge-shaped sleeve 220 and the second wedge-shaped sleeve 230 is increased, and the friction force between the plug pin assembly 200 and the hole wall of the vertical long hole arranged on the object to be hoisted is increased, so that the object to be hoisted is hoisted.
As shown in fig. 2 in conjunction with fig. 3, taking the first wedge sleeve 220 as an example, when the first wedge sleeve is subjected to the gravity G of the hoisted object during hoisting, the second wedge sleeve 230 applies a force F1 perpendicular to the inclined surface of the wedge sleeve and a force F2 perpendicular to the vertical surface of the wedge sleeve to the first wedge sleeve 220 through the inclined surface in contact with the first wedge sleeve 220, and it can be understood that the resultant force of the forces F1 and F2 is equal to and opposite to the gravity G. If the object to be hoisted is hoisted, the bolt assembly 200 is required to be placed in the vertical long hole position and cannot be separated from the vertical long hole position in the hoisting process. That is, the condition that friction force ≧ gravity needs to be satisfied, that is: g = F2 × tan θ ≦ F2 × μ, it is sufficient if tan θ ≦ μ is satisfied. Mu in the front formula is the friction coefficient between the bolt component and the hole wall of the vertical long hole, and the size of the friction coefficient depends on the material of the hoisted object arranged in the vertical long hole. In a specific embodiment of the present invention, the hoisting device is used to hoist the packaged battery pack, the plug pin assembly 200 and the mounting hole disposed on the packaged battery pack are required to be matched with each other, and the packaged battery pack is mostly made of aluminum, and under a normal condition, the friction coefficient of aluminum is 0.36, and when tan θ is less than or equal to 0.36, the mechanism can achieve self-locking. It should be noted that the value of 0.36 in the above description is only the friction coefficient between the lifting device and the packaged battery pack product in this embodiment, and if the material is changed, θ can be changed according to the change of the friction coefficient. The self-locking means that a friction force which is large enough can be generated between the bolt assembly 200 and a vertical long hole position arranged on an object to be hoisted to prevent the bolt assembly 200 from being separated from the vertical long hole, so that the packaged battery pack can be hoisted smoothly. That is, the inclined surfaces of the inclined end surfaces of the first wedge sleeve 220 and the second wedge sleeve 230 form an included angle θ with the extending direction of the pin 210, and tan θ is less than or equal to 0.36. As can be seen from the above, based on the above technical solution of the present invention, in practical applications, the range of tan θ can be selected according to different material requirements of an object to be hoisted, and meanwhile, different selections of the size proportional relationship between the first wedge-shaped sleeve 220, the second wedge-shaped sleeve 230, and the pin 210 in the axial direction and the radial direction are also required, which is not described herein again.
As shown in fig. 4 to 7, in another aspect, the invention further provides a hoisting tool for a packaged battery pack, which includes the hoisting device, and the number and the positions of the pin rod assemblies 200 are arranged corresponding to the vertical long hole positions on the packaged battery pack. In the embodiment shown in fig. 4 to 7, the vertical long holes are mounting holes 500 provided at the four end corners of the packaged battery pack. Specifically, the hoisting tool mainly comprises a framework 100, in order to make the structure simple and compact, the framework 100 adopts an I-shaped structure, four pin assemblies 200 are respectively arranged at four end corners of the I shape, and a lifting handle 300 is connected to the framework 100 through a spring 400; the plug pin assembly 200 includes a pin shaft 210 and first and second wedge sleeves 220 and 230 disposed about the pin shaft 210. In lifting device's use, skeleton 100 adopts great 5 to be aluminium material as whole atress subassembly, and the bottom surface adopts non-metallic material to wrap up, realizes the insulating function to battery module, prevents to take place incident such as electric leakage in the hoist and mount in-process. Four corners of the packaged battery pack are respectively provided with mounting holes 500 for inserting the four bolt assemblies 200 and hoisting the packaged battery pack. In the hoisting process, the lifting handle 300 is limited by the straight end 201 of the second wedge-shaped sleeve 230, and the lifting handle 300 is pulled upwards to drive the second wedge-shaped sleeve 230 to move upwards and compress the spring 400; first wedge sleeve 220 and the inclined plane of second wedge sleeve 230 slide of mutually supporting, area of contact between two telescopic inclined planes of gradual increase volume makes the cylindrical surface diameter grow that first wedge sleeve 220 and the combination of second wedge sleeve 230 formed, relative inflation in the mounting hole 500 of encapsulation battery package, and the module gravity that bears realizes hoist smoothly.
In the embodiment shown in fig. 1 to 5, the mounting holes for packaging the battery pack are all unthreaded holes, and a steel wire thread sleeve can be embedded inside the mounting holes and can be used for realizing assembly and fixation with other components through the steel wire thread sleeve. The invention realizes the hoisting of the packaged battery pack by utilizing the friction force between the unthreaded hole and the bolt component. However, the fitting relationship between the outer diameter of the pin rod and the inner diameters of the first and second wedge sleeves in the plug pin assembly, the length ratio between the pin rod and the first and second wedge sleeves, and the like need to be calculated and set in detail with respect to the conditions such as the magnitude of the friction coefficient of the material used, the weight of the object to be lifted, and the like. In addition, it should be noted that, in other hoisting product applications, if the vertical long hole position is not the unthreaded hole but the threaded hole, the screw thread in the threaded hole can increase friction force, and the above-mentioned structural arrangement is cooperated again, better effect can be reached.
Compared with the prior art, the hoisting tool for the packaged battery PACK can utilize the existing bolt mounting holes of the battery module to enable the bolt mounting holes to be universal as hoisting holes, and does not need to reserve the space between the end plate of the module and the side beam of the lower box body in the aspect of integral design of PACK, so that the energy density of the whole PACK is increased; because the hoisting direction is changed from the existing side part to the top part of the invention, extra external machining hole sites are not needed on the end plate surface, the manufacturing cost is reduced, and meanwhile, the positioning visual field is clear and visible, and the operation is convenient; in addition, the bolt mounting holes of the existing battery module are high in machining precision, so that the battery module is convenient to hoist and position; from the working principle, the hoisting device provided by the invention can be suitable for hoisting products with vertical long hole positions, and has a wide application range.
The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Within the scope of the technical idea of the invention, many simple modifications can be made to the technical solution of the invention, for example, the arrangement position and number of the plug pin assemblies can be adjusted according to different structures and shapes of the hoisted object. The invention is not described in detail in order to avoid unnecessary repetition. Such simple modifications and combinations should be considered within the scope of the present disclosure as well.
