[0026] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.
[0027] Example:
[0028] As attached Figure 1 To be continued Figure 7 As shown:
[0029] This utility model provides a safe building lifting device, including a main support rod 1; a connecting plate 101 is fixedly welded to the main support rod 1, and a reinforcing plate 102 is fixedly connected to the top surface of the connecting plate 101; an overload limit rod 5 is installed inside the connecting plate 101; an I-beam 2 is fixedly connected to the top surface of the reinforcing plate 102; an auxiliary pipe 31 is supported on the bottom surface of the base plate of the I-beam 2; a sleeve wheel 32 is sleeved on the lower part of the auxiliary pipe 31, and the sleeve wheel 32 and the auxiliary pipe 31 form an anti-tipping component 3; a fixed base 4 is installed on the front side of the main support rod 1, and an electrically controlled telescopic rod 401 is installed inside the fixed base 4. A collar 4011 is welded to the moving end of the electrically controlled telescopic rod 401, and the collar 4011 is sleeved on the outside of the auxiliary pipe 31.
[0030] As attached Figure 1As shown, the bottom plate of the I-beam 2 has a through groove, and the top surface of the I-beam 2 is welded with connecting plates 201 at equal intervals. The bottom end of the connecting plate 201 is fixedly welded with a sliding groove steel bar 202. The bottom of the sliding groove steel bar 202 has a through groove, and a hook 2022 is slidably engaged inside the through groove. A lifting coiler 2021 is installed at the front end of the I-beam 2. The winding machine of the lifting coiler 2021 is connected to a connecting belt. The connecting belt passes around the hook 2022, and the end of the connecting belt is connected to the main support rod 1. After the lifting coiler 2021 is started by the external remote control, the building material on the bottom hook can be lifted. After the lifting coiler 2021 winds up the connecting belt, it can approach the main support rod 1 to complete the lifting and movement of the building material (this is the prior art and is not shown in detail in the figure). The sliding groove steel bar 202 is used to satisfy the movement of the hook 2022.
[0031] As attached Figure 2 As shown, a connecting base plate 501 is installed at the bottom of the overweight limit rod 5. The connecting base plate 501 is connected to the ground by a screw, and the connecting base plate 501 is in contact with the bottom circular plate of the main support rod 1. When the connecting plate 101 is overloaded and tends to tilt, it will stretch the overweight limit rod 5. If the overweight is too great, it will break the overweight limit rod 5.
[0032] As attached Figure 3 and attached Figure 4 As shown, a circular plate with a protruding diameter is welded to the bottom of the main support rod 1. The circular plate is connected to the ground by long bolts. A vertical rectangular groove is opened on the front side of the inside of the circular plate. A reinforcing plate 103 is welded to the top surface of the circular plate. A notch is opened in the inside of the reinforcing plate 103 at the front end. The reinforcing plate 103 is used to increase the stability of the main support rod 1, while the reinforcing plate 102 is used to increase the stability of the I-beam 2.
[0033] As attached Figure 2 and attached Figure 5 As shown, a top plate 3101 is welded to the top surface of the auxiliary pipe 31, and a retaining bracket 3102 is fixedly welded to the top surface of the top plate 3101. Rollers are installed on the retaining bracket 3102. The retaining bracket 3102 passes through the through slot opened on the bottom surface of the I-beam 2, and the rollers are in contact with the top surface of the bottom plate of the I-beam 2. When the auxiliary pipe 31 moves left and right, the rollers can reduce the friction with the I-beam 2, thereby ensuring smooth sliding. At the same time, the top plate 3101 is used to provide auxiliary support for the bottom surface of the I-beam 2, thereby preventing it from tipping over.
[0034] As attached Figure 6 and attached Figure 7As shown, the top plate of the sleeve 32 is equipped with ball bearings inside. The ball bearings are attached to the top surface of the retaining plate 403 above the inner wall of the fixed base 4. The bottom surface of the sleeve 32 is equipped with ball bearings on both the upper and lower surfaces. The ball bearings are attached to the opposite surfaces of the two retaining plates 403 on the inner wall of the fixed base 4. When the electric telescopic rod 401 pushes the auxiliary tube 31 to move, the ball bearings can reduce friction, thereby ensuring smooth movement under the load of the I-beam 2.
[0035] As attached Figure 4 and attached Figure 7 As shown, a vertical insertion hole is provided on the rear side of the base plate of the fixed base 4, and a rod 402 is inserted into the insertion hole. The rod 402 passes through the rectangular groove inside the bottom circular plate of the main support rod 1. The fixed base 4 can be pre-fixed on the front side of the main support rod 1 by using the rod 402 to achieve initial quick fixation.
[0036] The specific usage and function of this embodiment are as follows:
[0037] In this utility model, when in actual use, the building materials to be lifted are first hung on the bottom hook of the lifting coiler 2021. After the lifting coiler 2021 is started to wind up the connecting belt through the external remote control, the building materials can be moved close to the main support rod 1 to complete the lifting and moving of the building materials.
[0038] If the connecting plate 101 is overloaded and begins to tilt, it will stretch the overload limit rod 5. If the overload is too great, the overload limit rod 5 will break, thus serving as a warning. If the lifting is overloaded, the electric telescopic rod 401 will be activated by the external remote control to move the auxiliary pipe 31, thereby achieving the anti-tipping effect of auxiliary support for the I-beam 2.
