DETAILED DESCRIPTION

[0035] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0036] Example 1: Reference Figure 1 and Figure 2 A clamping device comprises: a crossbeam 1, a driving mechanism 2, a clamping arm 3 and a high-strength rubber 4. The two driving mechanisms 2 are respectively installed on one side of the crossbeam 1 in the sling. The output end of the driving mechanism 2 is connected to the clamping arm 3. The end surface of the clamping arm 3 is equipped with the high-strength rubber 4. The two high-strength rubbers 4 are arranged opposite to each other.

[0037] The principle of the above scheme is:

[0038] Multiple battery cells are fixed by gluing or adhesive tape to form a module, and then the module is wrapped with a steel belt to form a module group. After the module is hoisted by the hoist, the driving mechanism 2 is started, and the driving mechanism 2 drives the two clamping arms 3 and the high-strength glue 4 to move toward each other. After the high-strength glue 4 clamps the end of the module, the driving mechanism 2 is closed.

[0039] The beneficial effects of the above scheme are:

[0040] By installing the adhesive 4 on the clamping arm 3, after the module is clamped, the adhesive 4 provides friction for the module during the hoisting process, thereby improving the stability of the module during movement, preventing the center of the module from being affected by gravity and causing the battery cells in the center to sink due to the loose fixation of the steel belt, glue or adhesive sticker, thereby preventing the battery cells in the module from scattering during hoisting;

[0041] At the same time, by using the high-strength glue 4, it is possible to prevent the clamping arm 3 from directly contacting the end surface of the module when the module is tightly clamped, thereby preventing the module from being squeezed and damaged.

[0042] Example 2: Reference Figure 2 and Figure 3The rubber 4 is provided with an air-filling chamber, which is connected to the end of the adjusting mechanism 5. A plurality of friction blocks 6 are provided in a rectangular array on the end face of the rubber 4. A guide groove is provided in the friction block 6. The open end of the guide groove is connected to the air-filling chamber. The adjusting mechanism 5 is connected to the air compressor. The air compressor is connected to the controller through a wire, and the controller is connected to the power supply through a wire 2.

[0043] The principle of the above scheme is:

[0044] When the module is hoisted, multiple friction blocks 6 arranged on the end face of the rubber 4 are directly in contact with the end face of the module and then squeezed. The height of the squeezed friction block 6 becomes lower, increasing the contact area with the module, and at the same time increasing the friction force of the friction block 6 and the rubber 4 on the end face of the module. Then, the air compressor is started through the controller, and the air compressor inflates the inflation cavity and the guide groove of the rubber 4 through the adjustment mechanism 5. After the inflation is completed, the air compressor stops working, and the air pressure in the inflation cavity and the guide groove is kept stable through the adjustment mechanism 5;

[0045] After the module is hoisted, the air compressor is started again through the controller, and the inflation chamber and the guide groove are deflated through the adjustment mechanism 5.

[0046] The beneficial effects of the above scheme are:

[0047] By setting the connection between the inflation cavity and the guide groove, the inflation cavity and the guide groove can be inflated. After the friction block 6 on the rubber 4 holds the module tightly, it prevents the clamp arm 3 from moving too far, which may cause the inflation cavity or the guide groove to be squeezed and deformed and damaged;

[0048] At the same time, inflating the inflation cavity and the guide groove can increase the elasticity of the adhesive 4. When the clamp arm 3 quickly clamps the module, the air in the adhesive 4 can provide a buffer for the clamp arm 3 and the adhesive 4 itself.

[0049] When the clamp arm 3 clamps a smaller module, it cannot stably clamp the smaller module due to the limitation of the moving distance of the clamp arm 3. The inflated urethane foam 4 and the friction block 6 can supplement the distance between the clamp arm 3 and the module.

[0050] Example 3: Reference Figure 3 A plurality of rubber tubes 8 are arranged in a rectangular array in the inflation cavity, the top end of the rubber tube 8 is inserted in the guide groove, the side wall of the rubber tube 8 is provided with an air guide groove 9, the top end of the air guide groove 9 is placed in the guide groove, and the bottom end of the air guide groove 9 is placed in the inflation cavity.

[0051] The principle of the above scheme is:

[0052] When the guide groove is inflated, air enters the rubber tube 8 through the air guide groove 9, and then enters the guide groove through the top end of the rubber tube 8. When the guide groove is exhausted or the friction block 6 is squeezed, air enters the air guide groove 9 through the rubber tube 8.

[0053] The beneficial effects of the above scheme are:

[0054] During inflation, the air guide groove 9 can limit the speed of the air entering the guide groove to prevent the guide groove from being overfilled due to excessive inflation speed;

[0055] The rubber tube 8 is inserted and matched with the guide groove to improve the stability of the friction block 6 when it contacts the end surface of the module;

[0056] The rubber tube 8 can provide a support point for the inflation cavity to prevent the friction block 6 in the middle of the rubber 4 from being sunken after being subjected to force; when the friction block 6 completes the clamping of the module and is hoisted, the rubber tube 8 can provide circumferential damping for the friction block 6 to prevent the module from moving relative to the hanger during hoisting, which may cause the friction block 6 or the rubber 4 to move relative to the clamp arm 3, thereby improving the stability of the rubber 4 during hoisting, reducing its possible movement during operation, and avoiding damage to the rubber 4 itself due to frequent movement.

[0057] Example 4: Reference Figure 3 A rounded corner is provided at the intersection of the top surface of the friction block 6 and its side wall.

[0058] The principle of the above scheme is:

[0059] After the friction block 6 contacts the end face of the module, the guide groove is inflated to expand the friction block 6, the top surface area of ​​the friction block 6 increases, and at the same time, the volume of the side wall of the friction block 6 expands in the circumferential direction.

[0060] The beneficial effects of the above scheme are:

[0061] After the top surface area of ​​the friction block 6 is increased, the side wall of the friction block 6 expands circumferentially through the guide volume of the rounded corners, thereby reducing the degree of deformation between the top surface of the friction block 6 and its side wall, and reducing edge damage of the friction block 6 caused by repeated inflation and deflation.

[0062] Example 5: Reference Figure 4 The driving mechanism 2 includes: a longitudinal beam 10, a cylinder 11 and a mounting plate 12. The longitudinal beams 10 are provided on both sides of the cross beam 1. The bottom end of the longitudinal beam 10 is slidably connected with a mounting plate 12. The top surface of the mounting plate 12 is connected to the output end of the cylinder 11. The cylinder 11 is installed on the cross beam 1. The cylinder 11 is connected to one end of the clamp arm switch through a second conduit. The other end of the clamp arm switch is connected to the second air compressor through a third conduit. The bottom end of the mounting plate 12 is connected to the top of the clamp arm 3.

[0063] The principle of the above scheme is:

[0064] When the two clamp arms 3 need to be brought closer to each other, the clamp arm switch is turned on, and the air in the air compressor 2 enters the clamp arm switch through the conduit 3, and then enters the cylinder 11 through the conduit 2. The output end of the cylinder 11 moves toward the direction of the crossbeam 1, and the output end of the cylinder 11 drives the mounting plate 12 to slide along the longitudinal beam 10, and the mounting plate 12 drives the clamp arm 3 to move;

[0065] When the two clamping arms 3 need to be moved away from each other, the clamping arm switch is closed to release the air in the conduit 2 and the cylinder 11, the output end of the cylinder 11 is reset, and the output end of the cylinder 11 drives the mounting plate 12 to move in the opposite direction along the longitudinal beam 10, and the mounting plate 12 drives the clamping arm 3 to move and reset.

[0066] The beneficial effects of the above scheme are:

[0067] The cylinder 11 is arranged to control the movement of the clamp arm 3, which can provide sufficient clamping force to prevent it from falling from the lifting device, thereby improving the safety during lifting.

[0068] Example 6: Reference Figure 4 A cylinder cover 13 is installed on each side of the crossbeam 1 to protect the cylinder 11.

[0069] The principle of the above scheme is:

[0070] A cylinder cover 13 is provided on the cross beam 1 to protect the cylinder 11 .

[0071] The beneficial effects of the above scheme are:

[0072] The cylinder 11 can be prevented from causing harm to the operator during operation, and dust or debris can be prevented from polluting the cylinder 11.

[0073] Example 7: Reference Figure 4 and Figure 5 The sling also includes: a lifting ring 14; two lifting rings 14 are installed on the crossbeam 1, and the bottom ends of two handles 15 are hinged on the crossbeam 1. One end of a connecting rod 16 is hinged on the side of the handle 15, and the other end of the connecting rod 16 is hinged to one end of a push rod. The push rod is slidably connected to the crossbeam 1, and a sliding seat 17 is installed on the other end of the push rod. The sliding seat 17 is slidably connected to the crossbeam 1, and the two sliding seats 17 are arranged opposite to each other, and a hook 18 is installed at the bottom of the sliding seat 17.

[0074] The principle of the above scheme is:

[0075] When the lifting device needs to be moved, the position of the steel hook at the output end of the crane is adjusted, and the lifting ring 14 can be hoisted;

[0076] After the hoist holds the module tightly, the two handles 15 are rotated to make the top ends of the two handles 15 approach each other. The movement of the handles 15 drives the connecting rod 16 hinged thereto to move toward the middle of the beam 1. The connecting rod 16 drives the push rod, the slide seat 17 and the hook 18 hinged thereto to move toward the middle of the beam 1. Finally, the hook 18 hoists the steel belt on the module.

[0077] The beneficial effects of the above scheme are:

[0078] A hook 18 is arranged in the device to hoist the steel belt, thereby improving the stability of the device when hoisting the module; at the same time, the module can be centered to prevent the center of gravity from being unstable when the hoist holds the module tightly.

[0079] Example 8: Reference Figure 1-Figure 13 The adjustment mechanism 5 includes: a plurality of bases 19 are mounted on the end surface of the clamp arm 3, a conduit 4 21 is mounted in the circular hole of the base 19, and two vertical plates 22 are parallelly mounted on the bottom wall of the base 19; a connecting pipe 23 is rotatably connected to each of the vertical plates 22, the ends of the two connecting pipes 23 are respectively connected to the middle of one side of a connecting pipe 24, the other end of one connecting pipe 23 is rotatably connected to the end of the conduit 4 21, the other end of the conduit 4 21 is connected to the air compressor, a connecting pipe 3 25 is slidably connected in the connecting pipe 24, and a ring-shaped rubber pad 26 is mounted on the top of the opening of the connecting pipe 3 25.

[0080] The principle of the above scheme is:

[0081] Before clamping the module, start the air compressor to supply air to duct four 21. Duct four 21 supplies air through connecting pipe 23, air guide hole 27, connecting pipe two 24 and connecting pipe three 25, and then supplies air to the end face of the module through the opening at the top of connecting pipe three 25.

[0082] The beneficial effects of the above scheme are:

[0083] The air blown out through the opening of the connecting pipe 3 25 can clean the end surface of the module, blow away excess dust, increase the friction force of the friction block 6 when holding the module, and prevent the module from slipping relative to the friction block 6.

[0084] Example 9: Reference Figure 1-Figure 13 The sealing disk at the bottom end of the connecting tube 3 25 is connected to the top end of the reset spring 46, the bottom end of the reset spring 46 is connected to the sealing disk 2, the sealing disk 2 is installed at the bottom end of the connecting tube 24, and an air guide hole 27 is opened on one side of the connecting tube 3 25, and the air guide hole 27 is connected to the end of the connecting tube 23;

[0085] The inner wall of the second connecting pipe 24 is provided with a damping ring 47, which is specifically made of rubber material, and the damping ring 47 is frictionally matched with the third connecting pipe 25;

[0086] A conduit 7 is installed in the circular hole 2 of the base 19, and the other end of another connecting pipe 23 is rotatably connected to the end of the conduit 7. One end of a torsion spring 28 is installed on the side wall of the vertical plate 22, and the other end of the torsion spring 28 is connected to the mounting ring on the connecting pipe 23. An air guide hole 29 is opened on the other side of the connecting pipe 3 25, and the bottom end of the air guide hole 29 is arranged above the connecting pipe 23. The top opening of the base 19 is plugged with an upper cover 20, and a guide groove 2 30 opened on the top surface of the upper cover 20 is slidably matched with the side wall of the connecting pipe 3 25.

[0087] The principle of the above scheme is:

[0088] When the module needs to be held tightly, the two clamp arms 3 move toward each other, the opening at the top of the connecting pipe 3 25 contacts and is blocked by the end face of the module, and the sealing effect is increased by the annular rubber pad 26 on the connecting pipe 3 25, and the clamp arm 3 continues to move, the connecting pipe 3 25 moves into the connecting pipe 2 24, and at the same time compresses the reset spring 46, and the air in the connecting pipe 24 enters into the other connecting pipe 23 through the air guide hole 29, and then enters into the conduit 7, and enters into the inflation chamber through the conduit 7 to inflate the rubber 4 and the friction block, and the air compressor is turned off after the inflation is completed;

[0089] After the clamping arms 3 have finished clamping the module, the two clamping arms 3 are moved to make a reverse movement, and the reset spring 46 is reset to drive the connecting pipe 3 25 to move upward along the connecting pipe 2 24. During the upward movement of the connecting pipe 3 25, the connecting pipe 3 25 is rubbed by the damping ring 47 and can rise at a uniform speed. The air in the inflation cavity and the guide groove is discharged through the duct 7, the connecting pipe 23, the second air guide hole 29 and the opening at the top of the connecting pipe 3 25.

[0090] The beneficial effects of the above scheme are:

[0091] The second air guide hole 29 is arranged above the connecting pipe 23. When the device does not hold the module tightly, the opening at the top of the connecting pipe 3 25 can be used for exhaust. When the module starts to be held tightly, the second air guide hole 29 is connected with the connecting pipe 23 and the conduit 7, and then the inflation cavity and the guide groove are inflated, which can avoid the excessive air in the urea 4 in advance and cause it to be overfilled. At the same time, the arrangement of the electrical parts in the device is simplified, and the cost of manufacturing the device is saved. The staggered arrangement of the second air guide hole 29 and the connecting pipe 23 improves the practicability of the device.

[0092] After the annular rubber pad 26 at the end of the connecting tube three 25 stops contacting with the end face of the module, the reset spring 46 can limit the reset speed of the connecting tube three 25. During the uniform reset process of the connecting tube three 25, it can ensure that the air guide hole 29 can release the air in the inflation cavity and the guide groove, thereby ensuring the rationality of the device and making full use of the components to achieve switching between multiple functions. At the same time, it can ensure that after the work of the excellent glue 4 is completed, no excess air will remain inside, thereby avoiding the rupture of the excellent glue 4 caused by re-inflation when the device works next time, thereby improving the safety of the device.

[0093] Example 10: Reference Figure 1-Figure 13 , a toothed ring 31 is mounted on the connecting tube 23, the toothed ring 31 is meshed with the gear 32, the gear 32 is mounted on the rotating shaft 33, the end of the rotating shaft 33 is rotatably connected to the vertical plate 22, the rotating shaft 33 is equipped with the top of a connecting rod 34, the bottom of the connecting rod 34 is hinged to one end of the second connecting rod 35, the other end of the second connecting rod 35 is hinged to one end of the third connecting rod 36, the third connecting rod 36 is slidably connected to the column shell 37, the column shell 37 is mounted on the conduit 7, the other end of the third connecting rod 36 is connected to the sealing disk 3 at the end of the fourth connecting tube 38, the other end of the fourth connecting tube 38 is equipped with a sealing disk 4, the fourth connecting tube 38 is slidably connected in the conduit 7, one side of the fourth connecting tube 38 is provided with an air guide hole 39, the air guide hole 39 is connected to the conduit 7, the other side of the fourth connecting tube 38 is provided with an air guide hole 40, the air guide hole 40 is staggered with the conduit 7, and the air guide hole 40 is far away from the third connecting rod 36;

[0094] The inner wall of the column housing 37 near the connecting rod 3 36 is provided with a contact switch, the specific model of the contact switch is: KW7-0 type, the input end of the contact switch is provided with a sealing disk 3 facing the connecting pipe 4 38, and the contact switch is connected to the controller through a wire 3;

[0095] A pressure relief valve is provided on the conduit 7, and a contact switch 2 is installed on the pressure relief valve. The contact switch 2 is of the same model as the contact switch, and the contact switch 2 is connected to the controller through a wire 4.

[0096] The principle of the above scheme is:

[0097] The rubber 4 on the clamp arm 3 holds the module tightly for hoisting. When the module accidentally slides downward relative to the hoist, the annular rubber pad 26 drives the end of the connecting tube 3 25 to move downward. At the same time, the connecting tube 3 25 slides relative to the guide groove 2 30. The connecting tube 3 25 drives the top of the connecting tube 24 to move downward. The connecting tube 24 as a whole rotates downward relative to the vertical plate 22 with the connecting tube 23 as the center. The rotation of the connecting tube 23 drives the gear ring 31 to rotate. At the same time, the torsion spring 28 is twisted, and the gear ring 31 drives the gear 32 meshing with it to rotate in the opposite direction. The gear 32 drives the bottom end of the connecting rod 34 to move downward. The connecting rod 34 drives the connecting rod 2 35 and the connecting rod 3 36 to move downward in turn, and finally drives the connecting tube 4 38 to move downward along the column shell 37. After the connecting tube 4 38 contacts the contact switch, the controller starts the air compressor to inflate the rubber 4. At this time, the conduction area between the air guide hole 40 and the conduit 7 increases, and the amount of air entering the rubber 4 increases, which instantly increases the holding force on the module and prevents the module from continuing to fall. When the pressure relief valve on the conduit 7 reaches the pressure relief pressure, the pressure relief valve opens the contact switch 2, and the controller turns off the air compressor to stop inflating the rubber 4.

[0098] After the module is hoisted and clamped, the torsion spring 28 drives the connecting tube 23 to reset, one end of the connecting tube 23 drives the connecting tubes 24 and 3 25 to reset, and the other end of the connecting tube 23 finally drives the connecting tube 4 38 to reset in the column shell 37.

[0099] The beneficial effects of the above scheme are:

[0100] The connecting rod 34, the second connecting rod 35 and the third connecting rod 36 are hinged in sequence to avoid the occurrence of a jam between the parts when the rotating shaft 33 rotates, improve the smoothness of the movement of the fourth connecting pipe 38 in the column housing 37, avoid friction between the above two parts, and extend the service life of the device;

[0101] The staggered arrangement of the air guide holes 40 and the duct 7 can buffer the airflow entering the rubber 4 to prevent the rubber 4 from being damaged due to inflation due to excessive airflow speed. At the same time, when the module held by the device accidentally slides down, the volume of air input into the rubber 4 by the air compressor can be quickly increased by increasing the conduction area of ​​the air guide holes 40 to the duct 7, thereby avoiding accidents in time.

[0102] Example 11: Reference Figure 1-Figure 13 The conduit 7 is provided with a column shell 2 41, the column shell 2 41 is adjacent to the PU 4, a rotating shaft 2 42 is rotatably connected inside the column shell 41, a plurality of fan blades 43 are mounted on the rotating shaft 42, a vibration wheel 44 is mounted on the end of the rotating shaft 42 passing through the column shell 2 41, a plurality of vibration blocks 45 are mounted on the side wall of the vibration wheel 44, and the vibration blocks 45 are frictionally matched with the side wall of the PU 4.

[0103] The principle of the above scheme is:

[0104] The air entering the second column shell 41 through the conduit 7 or the air entering the second column shell 41 from the inflation chamber can blow the fan blades 43 on the second shaft 42, and make the second shaft 42 rotate under the action of the flowing airflow. The rotation of the second shaft 42 drives the vibration wheel 44 to rotate, and the vibration wheel 44 drives the vibration block 45 to frictionally cooperate with the side wall of the rubber 4 and make the rubber 4 vibrate, so as to shake off the dust carried by the rubber 4 before or after work.

[0105] The beneficial effects of the above scheme are:

[0106] When the rubber 4 is inflated or deflated, the rubber 4 can be vibrated by the vibration block 45 on the vibration wheel 44, and the dust on the rubber 4 automatically falls off due to the vibration, which reduces the complexity of manual cleaning by operators and improves the cleanliness of parts.

[0107] Example 12: Reference Figure 1-Figure 13 A method for controlling the clamping of a sling is used to control a clamping device as described in any one of the above items, comprising the following steps:

[0108] A. Rotate the two handles 15 toward each other, so that the handles 15 drive the connecting rod 16, the push rod, and the slide 17 to move. The two slides 17 move relative to each other, and each drives a hook 18 to clamp the bottom end of the steel belt on the side of the module.

[0109] B. Start the second air compressor. The second air compressor supplies air to the clamp arm switch through the third conduit. The clamp arm switch is turned on to supply air to the cylinder 11 through the second conduit, and the two clamp arms 3 move relative to each other. The rubber 4 and the friction block 6 cooperate to hold the module tightly, and then the second air compressor is turned off.

[0110] C. Hook the steel hook at the output end of the crane onto the lifting ring 14, start the crane to move the lifting device, and move the module to the designated position.

[0111] The principles and beneficial effects of the above scheme are:

[0112] The handle 15 is used to drive the connecting rod 16 to move, and the connecting rod 16 drives the push rod and the slide 17 to move in turn. The slide 17 drives the hook 18 to clamp the bottom end of the steel belt on the side of the module, so as to quickly clamp the module. After the module is clamped, the air compressor 2 is used to supply air to the conduit 3, the clamp arm switch and the conduit 2 to the cylinder 11 in turn. The clamp arm switch is provided to prevent the cylinder 11 from being damaged due to excessive pressure during operation, and the cylinder 11 can also be quickly deflated to reset it, thereby improving the flexibility of the device during operation. The use of the high-strength rubber 4 and the friction block 6 to clamp the module improves the stability of the module during hoisting. The clamped module is moved to the designated position by the crane, thereby further improving the efficiency of the hoisting work.

They can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented.
