[0028] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0029] See also Figures 1 to 12 The present invention provides a stud bolt installation device for a hybrid tower wind turbine blade, which includes a base 1. A support block 2 and an outer ring 3 are respectively arranged on the front and rear sides of the upper end of the base 1. Universal wheels 15 are arranged around the base 1 so as to be adjustable in height. The universal wheels can conveniently move the device. A servo motor 6 is arranged on the support block 2 facing backward. A turntable 4 keyed to the output shaft of the servo motor 6 is rotatably arranged in the outer ring 3. The outer wall of the turntable 4 is evenly distributed with U-shaped material grooves 4.1 along the circumferential direction of its axis. The material grooves and the outer ring can limit the stud bolts. The stud bolts are arranged longitudinally to align with the screw holes of the blades, and the side wall of the outer ring 3 is inclined to open a feed port 3.1 for accommodating the stud bolts to enter the material trough 4.1. The outer ring 3 and the support block 2 are elastically and slidably equipped with a synchronous tightening mechanism 7 for synchronously screwing the stud bolts in the material trough 4.1 into the blades. The support block 2 is provided with a servo electric cylinder 8 and a driving assembly 10 for driving the synchronous tightening mechanism 7 to rotate. The piston rod end of the servo electric cylinder 8 is connected to a propeller 9 for pushing the synchronous tightening mechanism 7 to move backward and capable of driving the driving assembly 10. The servo motor drives the turntable to rotate and puts the studs into the feed port one by one. The studs enter the material trough one by one and are restricted. The turntable stops after rotating one circle. The loading of the studs is completed. Each stud corresponds to the screw hole of the blade. The device is pushed to the screw hole position of the blade and aligned. The servo electric cylinder drives the propeller to move backward. The propeller pushes the synchronous tightening mechanism to move backward and can drive the driving assembly to screw the synchronous tightening mechanism, so that the synchronous tightening mechanism synchronously screws the studs into the screw holes of the blades. Then the servo electric cylinder drives the propeller to move forward and reset. The synchronous tightening mechanism moves forward and resets under the action of elasticity. The synchronous tightening mechanism disengages from the studs, and the staff can push away the device.

[0030] The output shaft end of the servo motor 6 is rotatably provided with a connecting shaft, and a baffle plate 5 coaxially arranged with the turntable 4 is keyed on the connecting shaft. A through hole 5.1 is provided at the front end of the baffle plate 5, and a chamfer is provided at the front edge of the through hole. The chamfer can guide the stud bolt to stably enter the screw hole of the blade. The through hole 5.1 is located in the middle of two adjacent material troughs 4.1. The turntable 4 and the baffle plate 5 are provided with a return assembly 11 that allows the baffle plate 5 to rotate with the turntable 4. The pusher 8 drives the baffle plate 5 to deflect through the return assembly 11, so that the through hole 5.1 and the material trough 4.1 are on the same axis. When loading, the baffle plate rotates with the turntable, and the baffle plate can prevent the stud bolt from sliding backwards during the rotation of the turntable. After the turntable rotates one circle and the stud bolt is loaded (there is a stud bolt in each material trough), after loading, the pusher deflects the baffle plate by a certain angle through the return assembly, and the through hole and the material trough are on the same axis, so that the stud bolt is guided into the screw hole of the blade through the through hole.

[0031] The synchronous tightening mechanism 7 comprises a sliding plate 7.1 coaxially arranged with the rotating plate 4, a sub-gear 7.3 corresponding to the material trough 4.1 is rotatably arranged on the sliding plate 7.1, a screwdriver 7.4 is arranged at the center of the rear end of the sub-gear 7.3, an inner and outer gear 7.2 is meshed on the inner side of the sub-gear 7.3, and a limit gear 7.7 rotating on the sliding plate 7.1 and a driving gear 7.5 matched with the driving assembly 10 are respectively meshed at the upper and lower ends of the inner side of the inner and outer gears 7.2, and a limit plate 7.6 for limiting the inner and outer gears 7.2 is respectively arranged on the upper and lower sides of the rear end of the sliding plate 7.1. The driving gear is driven to rotate by the driving assembly, and the driving gear drives the screwdriver to screw through the inner and outer gears and the sub-gear, and at the same time, the synchronous tightening mechanism is pushed backward by the propulsion member, and the screwdriver that moves backward and screws the stud bolt into the screw hole of the blade.

[0032] The screwdriver 7.4 includes a sleeve coaxially arranged at the rear end of the divided gear 7.3, and a screwdriver head is elastically and telescopically arranged in the sleeve. When the screwdriver moves backward and rotates, the screwdriver head will contact the stud bolt, but it may not immediately fit into the hexagonal bolt hole of the stud bolt. The elastically telescopic screwdriver head can shrink to avoid hard pushing, and the rotating screwdriver head will pop out and reset after being inserted into the bolt hole and continue to screw the stud bolt.

[0033] See also Figure 1 , Figure 4 , Fig. 9The upper and lower ends of the outer ring 3 are vertically and symmetrically provided with a second sliding shaft 12 for slidingly matching the sliding disk 7.1 forward and backward. The lower second sliding shaft 12 is connected to the support block 2. The outer sleeve of the second sliding shaft 12 is provided with a shaft sleeve 13 locked by a locking bolt. The shaft sleeve can be adjusted forward and backward to adjust the forward and backward position of the synchronous tightening mechanism. The outer sleeve of the second sliding shaft 12 is provided with a second elastic member 14 connecting the outer ring 3 and the sliding disk 7.1. The pusher pushes the sliding disk to move backward along the second sliding shaft, and the sliding disk moves backward with other components of the synchronous tightening mechanism. After synchronous tightening, the pusher moves forward and resets, and the sliding disk moves forward and resets under the action of the second elastic member. The synchronous tightening mechanism can be stably supported and guided by the second sliding shaft, and the shaft sleeve can be adjusted forward and backward to adjust the forward and backward position of the synchronous tightening mechanism.

[0034] The driving assembly 10 includes a gear box 10.1 arranged at the rear end of the support block 2. The rear end and the left end of the gear box 10.1 are respectively connected to the first sliding shaft 10.2 and the ratchet shaft that pass through the sliding plate 7.1. The gear box is of existing technology and can increase or decrease speed, and can change the transmission direction and the rotation direction. The driving gear 7.5 is slidably fitted on the first sliding shaft 10.2 and rotates with the first sliding shaft 10.2. A ratchet 10.3 is keyed on the ratchet shaft, and a ratchet pawl 10.4 that is twisted against the ratchet 10.3 is twisted on the gear box 10.1. When the pusher 9 moves backward, the pusher 9 drives the ratchet 10.3 to rotate, and the ratchet drives the driving gear to rotate through the gear box and the first slide shaft. The driving gear drives the sub-gear to rotate through the internal and external gears. The rotating sub-gear drives the screwdriver to tighten, and at the same time, the pusher pushes the screwdriver to move backward, thereby screwing the stud bolt into the screw hole of the blade. When the pusher 9 moves forward, the pusher 9 no longer rotates the ratchet 10.3, and the synchronous tightening mechanism moves forward and resets under the action of the second elastic member. The ratchet does not move, the screwdriver will not reverse, and the stud bolt will not be screwed out.

[0035] See also Figure 1 , Figure 5 , Figure 8 , the turntable 4 and the baffle plate 5 are both provided with connecting plates, the aligning assembly 11 includes a lever 11.1 vertically connected to the baffle plate 5, the turntable 4 is connected with an arc-shaped sliding sleeve 11.2 for accommodating the lever 11.1 to slide, the track of the arc-shaped sliding sleeve is arranged coaxially with the turntable, the side wall of the connecting plate at the turntable 4 is provided with a connecting hole 11.3, and a first elastic member is connected between the connecting hole 11.3 and the lever 11.1. To reduce the overall weight, when the turntable rotates, the lever is pressed against the sliding sleeve under the action of the first elastic member, so that the baffle plate rotates with the turntable, the turntable stops after rotating one circle (stud bolt loading is completed), the pusher moves backward, and the pusher drives the lever to deflect to the right, after the lever deflects with the baffle plate, the through hole and the material trough are on the same axis, so that the stud bolt is guided through the through hole to be screwed into the screw hole of the blade.

[0036] The propulsion member 7 includes a push plate 9.1 on the right side for pushing the synchronous tightening mechanism 7 backward and a bending portion 9.2 on the left side. The bending portion 9.2 is composed of a first longitudinal bar extending backward on the upper side and a second longitudinal bar extending forward on the lower side connected by a vertical connecting bar. The lower end of the second longitudinal bar is equidistantly and elastically provided with a toggle block 9.3 for unilaterally driving the ratchet 10.3 to rotate. The rear end of the first longitudinal bar is provided with an inclined surface 9.4 for aligning the baffle plate 5 after deflection through a toggle rod 11.1. The front side of the lower end of the toggle block is an arc-shaped surface, and the piston rod of the servo electric cylinder is connected to the push plate. The pushing piece moves backward, and the synchronous tightening mechanism is pushed backward by the push plate, and the inclined surface of the first longitudinal strip drives the baffle plate to deflect and align through the toggle rod, and then the baffle plate does not move. At the same time, the toggle block pushes the ratchet to rotate, and the ratchet drives the driving gear to rotate through the gear box and the first sliding shaft. The driving gear drives the backward-moving screwdriver to be screwed clockwise through the internal and external gears and the sub-gear, thereby screwing the stud bolt into the screw hole of the blade, and the pushing piece moves forward, and the synchronous tightening mechanism moves forward and resets, and the toggle block retracts when passing the ratchet. The ratchet does not move, and the screwdriver will not reverse, and the stud bolt will not be screwed out. The toggle rod is separated from the first longitudinal strip. After being pushed away from the device, the toggle rod and the baffle plate are reset under the action of the second elastic member.

[0037] The specific working process of the present invention is as follows: the servo motor drives the turntable and the baffle plate to rotate and feed the stud bolts into the feed port in sequence, the stud bolts enter the material trough in sequence and are restricted, the turntable stops after rotating one circle, the stud bolt loading is completed, and the device is pushed to the screw hole position of the blade and aligned, such as Figure 6 , Figure 7 As shown, the servo electric cylinder drives the propulsion member to move backward, and the push plate drives the synchronous tightening mechanism to move backward. The inclined surface of the first longitudinal bar drives the baffle plate to deflect and align through the lever, and then the baffle plate does not move (the first longitudinal bar abuts the lever, so that the lever and the baffle plate do not move). At the same time, the lever block drives the ratchet to rotate, and the ratchet drives the driving gear to rotate through the gear box and the first sliding shaft. The driving gear drives the backward screwdriver to rotate clockwise through the internal and external gears and the sub-gear. At this time, the screwdriver has not yet touched the stud bolt, as shown in FIG. Figure 8 As shown, the pusher continues to move backward, and the screwdriver that moves backward and twists screws the stud bolt into the screw hole of the blade, as shown in FIG. Fig. 9 As shown, the pushing member then moves forward, and the synchronous tightening mechanism moves forward and resets under the action of the second elastic member. The toggle block retracts when passing the ratchet, and the ratchet does not move, so the screwdriver will not reverse, and the stud bolt will not be screwed out. The toggle rod is separated from the first longitudinal bar, and subsequently pushed away from the device, and the toggle rod and the baffle are reset under the action of the first elastic member.

[0038] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
