[0024] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to achieve. When the combination of technical solutions is contradictory or cannot be achieved, it should be considered that the combination of such technical solutions does not exist and is not within the scope of protection of this application.

[0025] In the embodiments of this application, please refer to Figure 1-5 As shown, this kind of movable small-scale building material lifting device mainly includes: a main frame 1, including a bracket 2 and a base plate 3; a lifting mechanism, located in the middle of the main frame 1, including a screw rod 4, a connecting rod group 5, a material discharge frame 6, a wire drum 21 and a lifting rope 7, an extension rod 20 is installed in the axial hole of the wire drum 21, and a first bevel gear 8 is installed at one end of the extension rod 20. A second bevel gear 9 is meshed with one end of the first bevel gear 8, and the second bevel gear 9 is installed on the screw rod 4 for lifting materials; a multi-purpose support frame 10, which can be detachably installed on the base plate 3 or the bracket 2, includes a support plate 107, a third gear 103, a first rack 101, a second rack 102 and a locking block 105, when installed on the base plate 3, it is used to support and fix the main frame 1, and when installed on the bracket 2, it is used to drag and move the overall structure.

[0026] Some preferred / improved embodiments based on the above embodiments will be described below. Any one of the following embodiments may be selected, or multiple embodiments may be selected and combined.

[0027] Reference Figure 1As shown, the bracket 2 has through holes 11 in pairs on the left and right sides, and the shape of the through holes 11 matches the locking block 105 for installing the multi-purpose support frame 10, and the width of the bracket 2 is slightly smaller than the width of the base plate 3 (not clearly shown in the figure), so that the multi-purpose support frame 10 can match it exactly.

[0028] Reference Figure 5 As shown, a connecting groove is provided on the support plate 107 for accommodating a spring 106, a first rack 101, a second rack 102, a third gear 103 and a locking block 105. A limiting rod is rotatably provided on the third gear 103. The limiting rod is installed in the connecting groove for supporting the third gear 103. The third gear 103 is meshed with the first rack 101 and the second rack 102.

[0029] Specifically, the locking block 105 is installed on the second rack 102 , and a button 104 is fixedly installed on one end of the first rack 101 , and the other end is connected to a spring 106 for locking and unlocking the locking block 105 .

[0030] like Figure 4 As shown, a groove 12 is provided on the base plate 3, which matches the size of the end of the support plate 107. When the support plate 107 is inserted into the base plate 3, the groove 12 is inclined so that when the support plate 107 is fixed on the base plate 3, the two have an angle, and the lower end of the support plate is in contact with the ground support, thereby fixing the main frame 1.

[0031] like Figure 3 As shown, the sling rope 7 is installed on the unloading frame 6, and one end of the sling rope 7 is installed on the bobbin 21 and can be wound around its axis.

[0032] Furthermore, two pulleys 22 are provided on the main frame 1, one of which is installed on the upper end of the bracket 2, and the other is installed on one side of the bracket 2. The position of the suspension rope 7 is fixed by the limiting effect of the two pulleys 22. At the same time, the fixation between the pulley 22 and the suspension rope 7 avoids direct contact with the bracket 2, reduces friction, and improves the continuity of the overall transmission.

[0033] Specifically, a motor 19 is installed on the bottom plate 3 , and an output end of the motor 19 is connected to an extension rod 20 .

[0034] In some embodiments, the first side 14 of the connecting rod group 5 is fixed to the base plate 3 by a fixing block 16, and the second side 15 of the connecting rod group is installed in the slide groove 17 and is connected to the screw rod 4 through an intermediate rod 18. When the motor 19 rotates in one direction, the extension rod 20 and the bobbin 21 are driven to rotate at the same time. On the one hand, the bobbin 21 is wound to pull the lifting rope 7 to lift the discharge frame 6 upward. On the other hand, the first bevel gear 8 at the end of the extension rod 20 is transmitted to the second bevel gear 9 on the screw rod 4, changing the transmission direction. The second bevel gear 9 wheel rotates, driving the screw rod 4 to rotate, driving the second side 15 of the connecting rod group 5 to move to the left through the slide groove 17, stretching the connecting rod group 5, driving the connecting rod group 5 to move upward, and synchronously lifting the discharge frame 6, further improving the stability of transporting materials in the working state.

[0035] Preferably, a moving wheel 13 is installed at the lower part of the base plate 3 to facilitate pushing and pulling the mobile body, and the moving wheel 13 has a locking function to facilitate fixing the overall structure and improve stability in the working state.

In order to avoid obscuring the concept of the present application, some details known in the art are not described. Based on the above description, those skilled in the art can fully understand how to implement the technical solution disclosed herein.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present application, and the aforementioned embodiments are only used to illustrate the technical solution of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, a person of ordinary skill in the art should understand that it is still possible to modify the technical solutions recorded in the aforementioned embodiments, or to make equivalent replacements for some of the technical features therein.
