The surface of the extension 22b is used for supporting the wall board, and forms a wall board placing position; the surface of the extension 22b is a horizontal plane. In addition, the height of the extension part 22b is lower than that of the fixing part 22a, and the joint between the extension part 22b and the fixing part 22a facilitates the abutting of the wall board.
The jacking transmission mechanism of the embodiment is arranged on the base 1 and used for driving the jacking frame 2 to move up and down along the height direction. Specifically, the jacking transmission mechanism comprises a driving wheel 3, a driven wheel 4, a linkage shaft 5, a worm wheel 6 and a worm 7.
Wherein, the driving wheel 3 is rotatably arranged on the overhead frame. Specifically, the driving pulley 3 is mounted inside the pedestal 21 of the overhead frame by a driving shaft 8, and the driving shaft 8 crosses both sides of the pedestal 21 of the overhead frame and is rotatably mounted to the overhead frame, for example: two ends of the transmission shaft are respectively arranged on two side walls of the base frame of the overhead frame through bearings, so that the transmission shaft is rotatably arranged on the overhead frame; one end of the transmission shaft 8 protrudes out of the base frame 21 of the overhead frame so as to be convenient for installing the hand crank 9; the handle 90 is arranged on the hand crank 9, which is convenient for driving the operation of the driving wheel. Wherein, the driving wheel 3 is arranged on the transmission shaft 8 through a flat key, and the driving wheel 3 is coaxial with the transmission shaft 8; the handle 90 is screwed in the threaded hole of the hand crank 9 through a threaded shaft to realize fixation.
The driving wheel 3 is meshed with the driven wheel 4, the driven wheel 4 and the worm wheel 6 are coaxially arranged through a linkage shaft 5 to be linked, and the linkage shaft 5 is rotatably arranged on the overhead frame. Specifically, the linkage shaft 5 spans two sides of the pedestal 21 of the overhead frame and is rotatably mounted on the overhead frame, and the linkage shaft 5 is parallel to the transmission shaft 8, for example: two ends of the universal driving shaft are respectively arranged on two side walls of the base frame of the overhead frame through bearings, so that the universal driving shaft can be rotatably arranged on the overhead frame. In addition, the driven wheel 4 and the worm wheel 6 are both arranged on the linkage shaft 5 through flat keys, and the driven wheel 4, the worm wheel 6 and the linkage shaft 5 are coaxial.
The worm wheel 6 of the embodiment is in transmission connection with the worm 7, and the worm 7 is fixedly arranged on the base. The driving wheel 3, the driven wheel 4, the linkage shaft 5, the worm wheel 6 and the worm 7 are all positioned on the inner side of the base frame of the overhead frame.
The base of this embodiment is further provided with a guide post 10, and correspondingly, the inner side wall of the base frame is provided with a guide groove 210 matched with the guide post. The number of the guide columns 10 of the present embodiment is two, and the guide columns correspond to the guide grooves of the base frame one by one. Wherein, two direction stand 10 and worm 7 are along horizontal plane circumference evenly distributed, along the circumference evenly distributed of base 1 promptly, hoisting device overall structure's stability. In addition, the guide upright post 10 and the jacking plate 22 are respectively positioned at two sides of the worm 7, so that the stress of the whole structure of the device is balanced.
The horizontal leveler 11 is arranged below the base of the embodiment, and when the height of the wallboard is adjusted on the non-horizontal ground, the wallboard jacking auxiliary device can be in a horizontal state through the horizontal leveler. The structure of the horizontal leveler 11 can be referred to in the prior art and will not be described in detail herein.
The braking mechanism of the embodiment is used for braking the reverse driving of the jacking transmission mechanism under the pressure action of the wallboard. The brake mechanism specifically comprises a brake ruler 12, a ratchet wheel 13 and a brake switch 14, wherein the ratchet wheel 13 is coaxially arranged on the linkage shaft 5 through a flat key, and the brake ruler 12 is arranged on one of the guide upright columns 10. In particular, one of the guide uprights 10 is fitted with a connecting element, for example: the clamp and other existing connecting pieces can be used; the brake switch 14 comprises a shifting lever and a rotating shaft, the shifting lever is connected with one end of the rotating shaft in a linkage manner, the other end of the rotating shaft penetrates through the base frame 21 and a connecting piece arranged on the guide upright post, the connecting piece is movably arranged on the guide upright post, so that the rotating shaft can be matched with the base frame and the connecting piece in a rotating manner, and the rotating shaft is connected with the brake ruler 12 in a linkage manner. By rotating the brake switch 14, the interlocking brake rule 12 rotates so as to engage with the ratchet 13 to brake or disengage from the ratchet 13 to release the brake. In addition, the lever of the brake switch 14 is located outside the pedestal 21 of the overhead for braking or brake release operation. In the braking releasing process, the operation of combining the handle and the shifting lever can be adopted, the handle is rotated, the clamping force between the braking ruler and the ratchet wheel is reduced or eliminated, and the shifting lever is shifted to release braking easily.
The operation flow of the wallboard jacking assisting device of the embodiment is as follows:
the whole device is placed on the ground, and can be leveled by a horizontal leveler if necessary;
the bottom of wallboard is withstood to the ceiling board, and the handle of shaking hand is held to operator's hand, rotates the shaking hand, drives the action wheel through the transmission shaft and rotates, and the action wheel drives from the driving wheel rotation through the meshing, and transmission power makes the universal driving shaft rotate simultaneously, and the worm wheel of universal driving shaft is driven in step, through worm wheel and worm cooperation for the ceiling board is whole by the lifting, plays the effect of raising the wallboard.
When the wall plate is adjusted to the target position, the brake switch is rotated, braking is realized through the clamping action of the ratchet wheel and the brake ruler, and the jacking transmission mechanism is prevented from reversely rotating after the jacking plate is pressed; if the height of the wall board is too high, the braking ruler is separated from the ratchet wheel only by rotating the braking switch, the adjustment can be performed in the opposite direction, and the braking can be performed by rotating the braking switch after the adjustment is completed.
Example two:
the jacking transmission mechanism of the embodiment is different from the first embodiment in that:
the bubble level meter is arranged on the base frame, so that whether the base frame is in a horizontal state or not can be conveniently observed; so that the wallboard jacking auxiliary device can be quickly adjusted to be in a horizontal state through the horizontal leveler.
Other structures can refer to the first embodiment.
Example three:
the jacking transmission mechanism of the embodiment is different from the first embodiment in that:
the number of the guide upright posts is not limited to two in the first embodiment, and can be one, three, four and the like, and correspondingly, the guide grooves on the base frame correspond to the guide upright posts one by one; the number of the guide upright columns and the guide grooves is designed according to actual requirements.
Other structures can refer to the first embodiment.
The foregoing has outlined rather broadly the preferred embodiments and principles of the present invention and it will be appreciated that those skilled in the art may devise variations of the present invention that are within the spirit and scope of the appended claims.
