[0024] See also Figures 1 to 4The utility model provides a technical solution: a site equipment lifting device for water plant construction, comprising: a support frame 2, support plates 8 are arranged on both sides of the support frame 2, a slide rail 7 is fixedly installed in the middle of the bottom end of the support plate 8, a movable frame 5 is symmetrically slidably installed on the surface of the slide rail 7, and a limit plate 4 is fixedly installed at the lower part of the movable frame 5; two groups of adjustment mechanisms 6, each group of adjustment mechanisms 6 includes a fixed plate 605, and the fixed plates 605 are respectively fixedly installed at the four corners of the top of the support plate 8 on the same side, and the fixed plates 605 on one side are rotatably installed with a double-headed screw 602 on one side, and the fixed plates 605 on the other side are fixedly installed with a guide rod 603 on the other side, and the front and rear sides of the outer periphery of the guide rod 603 are sleeved with springs 604, the outer periphery of the double-headed screw 602 is symmetrically threaded with an auxiliary plate 601, and the outer periphery of the guide rod 603 is slidably installed There are auxiliary plates 601, and the lower parts of the two auxiliary plates 601 are fixedly installed on the surface of the limiting plate 4 on the same side. A driving mechanism 3 is arranged in each group of adjusting mechanisms 6. The staff can realize the synchronous rotation of the double-headed screw 602 by controlling the driving mechanism 3. Since the threads at both ends of the double-headed screw 602 have opposite rotation directions, the auxiliary plates 601 can move toward each other axially along the guide rod 603 with the cooperation of the threads. Since the auxiliary plates 601 are connected to the limiting plates 4, the limiting plates 4 can move toward each other along the slide rails 7 in cooperation with the moving frame 5. Since the position between the limiting plates 4 can be automatically adjusted, it is convenient for the staff to lift some large goods in the water plant site, and the staff does not need to adjust the spacing between the limiting plates 4, which not only reduces the workload of the staff, but also increases the lifting efficiency of building materials on the construction site.

[0025] A lifting steel cable 1 is provided at the top of the support frame 2, and the lifting steel cable 1 is connected to an external auxiliary mobile device. By providing the lifting steel cable 1, the stability of the lifting device can be increased to prevent the lifting device from falling due to the heavy weight of the construction materials during the lifting process. In addition, the lifting device is connected to the external auxiliary mobile device, which can facilitate the staff to move the lifted construction materials. The driving mechanism 3 includes a motor mounting frame 304, and the motor mounting frame 304 is respectively fixedly installed at the middle of the rear side of the support plate 8 on the same side. A stepper motor 301 is fixedly installed in the middle of the motor mounting frame 304, and a driving wheel 30 is fixedly installed at the driving end of the stepper motor 301. 3, the driving wheels 303 drive the driven wheels 305 on the same side to rotate through the synchronous belt 302, and the driven wheels 305 are respectively fixedly installed on the rear ends of the double-headed screw rods 602 on the same side. The staff can remotely control the stepper motor 301 in the driving mechanism 3 to rotate through the wireless network. Since the driving wheel 303 is connected to the driven wheel 305 through the synchronous belt 302, when the stepper motor 301 drives the driving wheel 303 to rotate, the double-headed screw rod 602 can rotate synchronously, and then the auxiliary plate 601 can be used to push the limit plate 4 to move toward each other, which can adapt to the limit of building materials of different sizes and facilitate the lifting device to lift the building materials on the construction site.

[0026] The movable frame 5 is provided with an installation groove 502 in the middle part, and a plurality of evenly distributed balls 501 are embedded and installed in the installation groove 502. By setting the ball 501, the sliding friction force of the movable frame 5 moving along the slide rail 7 can be converted into rolling friction, thereby reducing the friction force between the movable frame 5 and the slide rail 7, which is beneficial to improving the movement smoothness of the limit plate 4. One end of the spring 604 is fixedly installed on the other side auxiliary plate 601 close to the middle of the same side fixed plate 605, and the other end of the spring 604 is fixedly installed on the other side fixed plate 605 close to the middle of the same side auxiliary plate 601. The support plate 8 is detachably connected to the support frame 2 by fixing bolts. By setting the support plate 8 and the support frame 2 to be detachable, it is convenient for the staff to adjust the limit plate 4 as a whole, and only the corresponding fixing bolts need to be removed during the adjustment process, which is convenient for the staff to make relevant adjustments according to the on-site lifting requirements, which is beneficial to increasing the applicability of the lifting device.

[0027] During actual use, the staff connects the lifting ring on the lifting cable 1 with an external auxiliary mobile device. At this time, the external auxiliary mobile device moves the lifting device to the vicinity of the building materials. Then, the staff remotely controls the stepper motor 301. At this time, the stepper motor 301 cooperates with the driving wheel 303, the driven wheel 305 and the synchronous belt 302 to realize the rotation of the double-headed screw 602. Due to the characteristics of the thread, the auxiliary plate 601 will push the limit plate 4 to cooperate with the moving frame 5 to move toward each other along the slide rail 7 until the limit plate 4 limits and fixes the relevant building materials. After the limitation is completed, the lifting device cooperates with the external auxiliary mobile device to move the building materials to the desired position. Then, the driving mechanism 3 cooperates with the adjusting mechanism 6 to release the limit of the building materials, which is beneficial to improve the applicability of the lifting device and improve the lifting efficiency.

[0028] Compared with the prior art, the beneficial effects of the utility model are:

[0029] The utility model provides an adjusting mechanism and a driving mechanism in the lifting device for waterworks construction site equipment. The staff can remotely control the stepper motor in the driving mechanism. At this time, the stepper motor cooperates with the driving wheel, the driven wheel and the synchronous belt to realize the rotation of the double-headed screw. Due to the characteristics of the thread, the auxiliary plate will push the limit plate to cooperate with the moving frame to move toward each other along the slide rail until the limit plate limits and fixes the relevant building materials, thereby realizing full-automatic operation without manual participation, saving time and effort, not only improving the lifting efficiency, but also reducing the safety hazards in the lifting process, and ensuring the personal safety of the staff.

[0030] Although the above describes the illustrative specific implementation methods of the present application so that technicians in this technical field can understand the present application, the present application is not limited to the scope of the specific implementation methods.
