DETAILED DESCRIPTION

[0030] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0031] Embodiment 1:

[0032] like Figures 1 to 4 As shown, a prefabricated side wall installation auxiliary device for an assembly trolley of the present invention comprises a trolley body 1, and two installation auxiliary devices 2 are symmetrically installed on both sides of the top of the trolley body 1;

[0033] The installation auxiliary device 2 includes an articulated seat 21 and a mounting seat 22. The articulated seat 21 is articulatedly mounted with a base 23. The mounting seat 22 is mounted with a first motor 24. The output end of the first motor 24 is connected to the articulated shaft of the base 23. The base 23 is articulatedly mounted with an upper rod 25. The upper rod 25 is provided with a slideway 26. The slideway 26 is slidably mounted with a lower rod 27. The upper rod 25 is mounted with a rope reel 28. The steel rope on the rope reel 28 is connected to the end center position of the lower rod 27. The lower rod 27 is mounted with a guide rail 29. The guide rail 29 is slidably mounted with a slider 210. The lower rod 27 is mounted with a first oil cylinder 211. The output end of the first oil cylinder 211 is connected to the top center position of the slider 210. The slider 210 is integrally connected with a lower buckle plate 212. The slider 210 is slidably mounted with an upper buckle plate 213. The slider 210 is mounted with a second oil cylinder 214. The output end of the second oil cylinder 214 is connected to the top center position of the upper buckle plate 213.

[0034] In this implementation case, when using a prefabricated side wall installation auxiliary device for an assembly trolley, the trolley body 1 realizes position adjustment in the front-back and up-down directions, and the installation auxiliary device 2 realizes grabbing and moving the prefabricated side wall to the corresponding height;

[0035] Specifically, the operation mode of the installation auxiliary device 2 is that the first motor 24 runs, driving the base 23 to rotate on the hinge seat 21, so that the upper rod 25 moves vertically to the ground under its own weight, and then starts to run. This action realizes the storage of the upper rod 25 when not in use, which is convenient for storage;

[0036] After the upper rod 25 is perpendicular to the ground under its own weight, the operation of the rope reel 28 can be controlled to realize the lifting and lowering movement of the lower rod 27 in the slideway 26 of the upper rod 25, thereby realizing the stroke adjustment of the slider 210. After the position of the lower rod 27 is determined, that is, the lower end of the lower rod 27 is close to the ground, the rope reel 28 is stopped. The advantage of using the rope reel 28 instead of the oil cylinder to lift the lower rod 27 is that the steel rope is more durable than the output shaft of the oil cylinder, and is not prone to breakage, thereby ensuring the service life;

[0037] The prefabricated side wall is placed on the lower buckle plate 213, and then the second oil cylinder 214 is started to drive the upper buckle plate 213 to move toward the lower buckle plate 212, thereby clamping the prefabricated side wall. Then the first oil cylinder 211 is operated to drive the slider 210 to move on the lower rod 27, thereby realizing the lifting operation of the prefabricated side wall. After lifting to the required height, the relevant staff can take out the prefabricated side wall for installation. The horizontal lifting and moving structure makes the overall lifting of the prefabricated side wall horizontal, and there will be no tilting phenomenon, so it is more convenient when installing and aligning.

[0038] Furthermore, although not shown in the figure, a horizontal slide rail can be installed at the bottom of the articulated seat 21 to achieve overall horizontal displacement of the articulated seat 21, thereby achieving horizontal transfer of the prefabricated side wall and enhancing the auxiliary installation effect. The reason why the horizontal slide rail is not actually installed is that in actual construction, the track used to support the trolley body 1 is mostly close to the installation side wall, so in actual use, the distance between the lifted prefabricated side wall and the installation side wall is not far, and it can be directly taken out and placed, so the purchase cost of the horizontal slide rail is saved. In addition, it is found in actual use that the present structure has very high requirements on the bearing capacity of the horizontal slide rail, which leads to the problem that the track of the horizontal slide rail is prone to deformation after a period of use, and the failure rate and economy are increased.

[0039] Embodiment 2:

[0040] like Figure 1 , Figure 2As shown, the trolley body 1 of the present invention includes a bottom plate 11, a first angle plate 12, a second angle plate 13 and a third angle plate 14, the bottom plate 11 is plugged with the first angle plate 12 and the third angle plate 14, the second angle plate 13 is plugged with the first angle plate 12 and the third angle plate 14, the bottom plate 11, the first angle plate 12, the second angle plate 13 and the third angle plate 14 are all installed with a second motor 15, the output end of the second motor 15 is connected to a gearbox 16, the output end of the gearbox 16 is connected to a running wheel 17, the running wheel 17 is installed at the bottom of the corresponding bottom plate 11, the first angle plate 12, the second angle plate 13 and the third angle plate 14, and a plurality of first pin holes 18 are evenly arranged at the plug-in locations of the bottom plate 11, the first angle plate 12, the second angle plate 13 and the third angle plate 14. Such a design can realize the bottom plate 11. The positions of the first angle plate 12, the second angle plate 13 and the third angle plate 14 are adjusted relative to each other, so that they can be used in conjunction with tracks of different prefabricated specifications. Among them, the base plate 11, the first angle plate 12, the second angle plate 13 and the third angle plate 14 are separate individuals, which are connected by plugging. Therefore, the distance between the base plate 11, the first angle plate 12, the second angle plate 13 and the third angle plate 14 can be arranged according to specific circumstances and then fixed to adapt to the use of tracks of different widths. The requirements for the prefabricated installation distance of the track are low, and the wide adaptation range of the trolley body is conducive to multiple uses of one machine. It can be used not only as a carrier for installing the auxiliary device 2, but also as a carrier for other auxiliary equipment, thereby improving economic benefits.

[0041] Embodiment three:

[0042] like Figure 1 , Figure 2 and Figure 4 As shown, the trolley body 1 of the present invention is provided with a rectangular column 19 on the upper sides of the bottom plate 11, the first angle plate 12, the second angle plate 13 and the third angle plate 14, and a third oil cylinder 110 is installed at the center position inside the rectangular column 19, and the output end of the third oil cylinder 110 is connected with a lifting column 111, and the lifting column 111 is slidably matched with the upper side of the rectangular column 19, and the lifting column 111 is gap-matched with the rectangular column 19. With such a design, the synchronous operation of the third oil cylinder 110 controlling the positions of the four corners can realize the overall elevation of the trolley body of the entire device, thereby expanding the longitudinal operating range of the installation auxiliary device. Among them, the power for lifting and lowering adjustment is not limited to the oil cylinder, and the cooperation of the lifting column 111 and the rectangular column 19 ensures that there is no deviation during the adjustment process of the total length of the two, thereby ensuring the horizontal support effect, and the adjustable lifting height is of self-evident importance in the construction process, which increases the transfer range of the prefabricated side wall, and can also be used as a workbench for the construction of objects on the top of the construction area, thereby improving functionality.

[0043] Embodiment 4:

The cooperation of the upper ladder 115 and the lower ladder 113 is convenient for users to go back and forth between the workbench 114 and the base plate. Among them, the electric control box 112 serves as a carrier of power supply and control, and can also be used as an operating table and a storage room for sundries, making it easier to obtain construction accessories. The sliding matching of the lower ladder 113 and the upper ladder 115 can ensure normal use even when the height of the workbench 114 is adjusted.

[0045] Embodiment five:

Such a design serves the purpose of auxiliary positioning, and the position will not move even if impacted by excessive force. Among them, under the dead weight of the upper rod 25 and the lower rod 27, general impact cannot achieve the angular rotation of the upper rod 25 and the lower rod 27 at the hinge of the base 23, so under normal circumstances, there is no need to fix them, but the installation of the pin hole 215 can ensure that the angle between the upper rod 25 and the base 23 is a right angle by inserting a pin, and enhances the impact resistance effect.

[0047] Preferably, a telescopic guide rod 118 is installed between the workbench 114, the base plate 11 and the third angle plate 14.

[0049] Preferably, the base 23 is provided with a groove 216 whose specifications and dimensions match those of the upper rod 25. Such a design serves the purpose of limiting, so that the upper rod 25 can better cooperate with the base 23 when it is retracted. In fact, the depth dimension of the groove 216 can also be considered according to specific circumstances.

[0050] Preferably, the guardrail 117 is installed with an opening and closing door 120, and steel plates are laid between two adjacent guardrails 117 and between the adjacent bottom plates 11, first angle plates 12, second angle plates 13 and third angle plates 14. Such a design enables movement between the various workbenches 114. In fact, measures that facilitate movement between the various workbenches can also be considered based on specific circumstances.

[0051] Preferably, the upper buckle plate 213 is fixedly installed with a guide rod 217 slidably installed on the slider 210.
