Description

Technical Field

[0001] The invention relates to the technical field of electric cranks, in particular to a handheld detachable gate electric crank. Background Art

[0002] In water conservancy projects, gates are often needed to precisely control the size of water flows, and can also be used to rationally allocate irrigation water. This rational allocation of irrigation water can meet the corresponding water resource needs in different seasons and under different irrigation needs according to actual conditions, while also reducing the waste of water resources. The opening and closing of gates generally require a gate hoist to start.

[0003] At present, gate hoists are mainly divided into electric gate hoists and manual gate hoists. Manual gate hoists require manual rotation of a crank to operate the gate hoist to adjust the gate; while electric gate hoists require a motor to drive the gate hoist. Both manual and electric gate hoists are equipped with a manual crank. Although this crank is not energy-restricted, it requires manual rotation by staff, which is time-consuming and labor-intensive. When faced with a large number of gates, it is not enough. Therefore, a handheld, detachable gate electric crank that can save manpower and increase gate opening and closing efficiency is needed to address the shortcomings of existing gate hoist cranks.

[0004] For example, the patent with announcement number CN213858991U provides a connecting crank, which includes a rough connecting structure and a locking structure; the protruding part of the application constitutes a accommodating space for accommodating the workpiece to be tightened; however, this solution is still a traditional manual crank, which cannot save manpower and cannot improve the efficiency of opening and closing the gate; the electric crank in the prior art uses a direct motor drive method to transmit torque and has no active heat dissipation function. Long-term operation can easily cause the motor to overheat, thereby reducing the service life of the equipment; this solution can easily cause the connector to be compressed, deformed and worn when the gate or gate opening machine is stuck, thereby causing damage to the connecting crank; the electric crank in the prior art cannot adjust the output torque of the electric crank accordingly when the gate or gate opening machine is stuck; the existing electric crank cannot be converted to manual crank mode when the battery is low; the existing electric crank cannot be quickly disassembled, which makes it inconvenient to maintain and repair the inside of the crank.

[0040] Working principle of the present invention: Figure 1The present invention provides usage methods and corresponding scenarios.

The retaining device 3 is the core of the use process of the electric crank.

[0041] Taking the preferred embodiment as an example, first, according to the size of the joint on the gate hoist, the amount of hydraulic oil in the liquid clamp cylinder 104 is manually adjusted, so that the hydraulic oil drives the liquid clamp column 103 to expand and contract in the liquid clamp cylinder 104, thereby adjusting the initial distance between each liquid clamp column 103 on the liquid clamp sleeve 102 to adapt to the size of the joint on the gate hoist, thereby realizing the function of manually adjusting the clamping range of the liquid clamp column 103; when the liquid clamp column 103 clamps the joint of the gate hoist, the bidirectional motor 405 drives the hollow shaft 406 to rotate, and the hollow shaft 406 drives the connecting rotating shaft 202 on the connecting device 2 to rotate through the cooperation of the driving convex teeth 410 at the front end of the hexagonal rotating shaft 407 and the connecting groove 206 at the rear end of the connecting rotating shaft 202, and the connecting rotating shaft 202 is connected.

At this time, it is necessary to manually insert the hexagonal wrench into the rear end of the hexagonal rotating shaft 407, and then manually rotate the hexagonal wrench so that the hexagonal wrench drives the hexagonal rotating shaft 407 to rotate, thereby realizing the mode conversion function of the drive device 4; when the hollow rotating shaft 406 rotates, the hollow rotating shaft 406 drives the fan blades 507 and the circulating ring 508 on the circulation component 505 to rotate synchronously, and the circulating ring 508 also drives the stirring column 506 to stir the coolant in the heat dissipation sleeve 504, thereby realizing Active cooling function for the bidirectional motor 405; when the torque output on the liquid clamp sleeve 102 is insufficient, a hydraulic torque converter can be installed between the connecting fixed disk 201 and the liquid clamp fixed disk 101 by bolts, and the front end of the hydraulic torque converter is fixedly connected to the rear end of the liquid clamp fixed disk 101 by bolts, and the rear end of the hydraulic torque converter is fixedly connected to the front end of the connecting fixed disk 201 by bolts. Then the hydraulic torque converter will amplify the output torque of the connecting rotating shaft 202 and transmit it to the liquid clamp sleeve 102, and the liquid clamp sleeve 102 drives the gate opening machine to rotate through the liquid clamp column 103 to realize the torque transmission and amplification function; when the connecting device 2 is disassembled from the retaining device 3 and the driving device 4, first align the fixing slot 309 with the driving clamp plate 408 When the pin at the upper end is pulled out, the locking sleeve 306 on the locking assembly 303 is manually driven to slide backward. At this time, the connecting block 205 on the connecting cone 204 will gradually disengage from the locking groove 307 and the locking protruding tooth 308, causing the rubber splint 312 to expand outward and recover. The rubber splint 312 drives the locking plunger 313 to retract into the interior of the locking sleeve 306 through the elastic force during the recovery process. At this time, the hydraulic oil in the locking sleeve 306 drives the locking protruding tooth 308 to pop out again. Then, the tapered sleeve 401 is manually loosened from the front end of the driving sleeve 402, and the connecting device 2 and the first ball bearing 302 can be pulled out from the interior of the retaining device 3, so as to realize the maintenance and replacement function of the retaining device 3, thereby extending the service life;The hydraulic oil in the liquid clamp cylinder 104 can also play a buffering role on the liquid clamp column 103, preventing the liquid clamp column 103 from being hard damaged when overloaded.

[0042] Specifically, such as Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, first manually hold the driving handle 404 so that the liquid clamp sleeve 102 is aligned with the joint on the gate hoist, and then manually adjust the amount of hydraulic oil in the liquid clamp sleeve 104 according to the size of the joint on the gate hoist, so that the hydraulic oil drives the liquid clamp column 103 to expand and contract in the liquid clamp sleeve 104, thereby adjusting the initial distance between the liquid clamp columns 103 on the liquid clamp sleeve 102 to adapt to the size of the joint on the gate hoist, thereby realizing the function of manually adjusting the clamping range of the liquid clamp column 103; at the same time, the hydraulic oil in the liquid clamp sleeve 104 can also play a buffering role on the liquid clamp column 103, preventing the liquid clamp column 103 from generating when overloaded. Hard damage; when the torque output on the liquid clamp sleeve 102 is insufficient, a hydraulic torque converter can be installed between the connecting fixed plate 201 and the liquid clamp fixed plate 101 by bolts, and the front end of the hydraulic torque converter is fixedly connected to the rear end of the liquid clamp fixed plate 101 by bolts, and the rear end of the hydraulic torque converter is fixedly connected to the front end of the connecting fixed plate 201 by bolts. Then the hydraulic torque converter will amplify the output torque of the connecting rotating shaft 202 and transmit it to the liquid clamp sleeve 102, and the liquid clamp sleeve 102 drives the hoist to rotate through the liquid clamp column 103 to realize the torque transmission and amplification function; when the connecting device 2 is removed from the retaining device 3 and the driving device When disassembling in position 4, first pull out the pin from the fixed slot 309 on the first slider 310 and the driving locking plate 408 on the driving slide 412, then manually drive the first slider 310 on the locking assembly 303 to slide backward on the locking ring 304, and the first slider 310 drives the locking sleeve 306 and the second slider 311 to slide backward. At this time, the connecting block 205 on the connecting cone 204 will gradually disengage from the locking slide 307 and the locking convex teeth 308, so that the rubber splint 312 will open outward and recover. The rubber splint 312 drives the locking plunger 313 to retract to the locking position through the elastic force during the recovery process. Inside the sleeve 306, the hydraulic oil inside the locking sleeve 306 will drive the locking convex tooth 308 to pop out again, and then the tapered sleeve 401 is manually loosened from the front end of the driving sleeve 402, so that the connecting device 2 and the first ball bearing 302 can be pulled out from the inside of the retaining device 3 to realize the maintenance and replacement function of the retaining device 3, thereby extending the service life; the fixed cone column 203 is temporarily fixed by the extrusion force and friction force after the tapered sleeve 401 is tightened; the retaining sleeve 301 and the locking ring 304 are used for positioning the first ball bearing 302 and the second ball bearing 305.

[0043] like Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 and Figure 11 As shown, after the liquid clamping column 103 clamps the joint of the gate hoist, the driving switch 403 on the driving handle 404 is pressed, and the driving switch 403 will energize the bidirectional motor 405 and the battery 411, so that the bidirectional motor 405 drives the hollow rotating shaft 406 to rotate, and the hollow rotating shaft 406 drives the connecting rotating shaft 202 on the connecting device 2 to rotate through the driving convex teeth 410 at the front end of the inner hexagonal rotating shaft 407 and the connecting groove 206 at the rear end of the connecting rotating shaft 202. The connecting rotating shaft 202 drives the gate hoist to rotate through the liquid clamping sleeve 102 and the liquid clamping column 103, and the gate hoist drives the gate to open and close to realize electric control of the gate; when the battery 411 is in a low-power state, the bidirectional motor 405 cannot rotate automatically. At this time, it is necessary to manually insert the inner hexagonal wrench into the rear end of the inner hexagonal rotating shaft 407, and then manually rotate the inner hexagonal wrench so that the inner hexagonal wrench Drive the hexagonal shaft 407 to rotate to realize the mode conversion function of the drive device 4; when the bidirectional motor 405 rotates, the bidirectional motor 405 generates heat, and this heat generally accumulates inside the bidirectional motor 405. At this time, the heat dissipation copper column 501 and the heat dissipation copper ring 502 in the heat dissipation cavity 409 will first absorb the heat, and then transfer the heat to the coolant in the heat dissipation sleeve 504. At this time, the hollow shaft 406 will drive the fan blades 507 and the circulation ring 508 on the circulation component 505 to rotate synchronously. The fan blades 507 will blow the heat generated by the bidirectional motor 405 backward from the heat dissipation cover 503, and the circulation ring 508 will drive the stirring column 506 to stir the coolant in the heat dissipation sleeve 504, so that the coolant and the heat in the heat dissipation copper column 501 and the heat dissipation copper ring 502 are fully exchanged to realize the active cooling function of the heat dissipation device 5 on the bidirectional motor 405.
