[0001] This utility model relates to the field of lifting device technology, specifically a lifting device for construction engineering with a stabilizing mechanism. Background Technology

[0002] During construction, it is often necessary to work at heights, and lifting devices are commonly used equipment. Lifting devices move workers up and down to enable them to carry out construction work at heights. There are various types of existing lifting devices. Lifting vehicles with X-shaped lifting supports are a relatively common type of lifting device, which has the advantages of being easy to move, simple to operate, and small in size. However, when this type of lifting device is raised to a height, its small size can easily cause instability of the center of gravity, and its overall stability needs to be improved.

The X-shaped lifting bracket 3 is connected between the base and the top platform. The X-shaped lifting bracket 3 includes multiple X-shaped lifting rods and top rods connected sequentially in the vertical direction. The top rods are hydraulic, pneumatic, or electric. One end of the lowest X-shaped lifting rod in the X-shaped lifting bracket 3 is slidably and rotatably connected to the base through a bracket.

The other end of the highest X-shaped lifting rod in the X-shaped lifting bracket 3 is fixedly and rotatably connected to the top platform through a bracket. Four wheels are connected to the bottom of the base.

[0017] In the prior art, each X-shaped lifting rod includes two parallel X-plate assemblies that rotate through two central pivots. Both ends of the two X-plate assemblies are also rotatably connected to shafts. The bottommost X-shaped lifting rod of the X-shaped lifting bracket 3 is slidably and rotatably connected to the base through the bracket. In fact, one shaft at both ends of the X-plate assembly is slidably and rotatably connected to the base through the bracket. The bracket here is provided with a sliding groove, and one shaft at both ends of the X-plate assembly is slidably and rotatably connected to the sliding groove.

[0018] The bottommost X-shaped lifting rod of the X-type lifting bracket 3 is fixed and rotatably connected to the base through the bracket. In fact, it is another shaft at both ends of the X-plate group that is fixed and rotatably connected to the base through the bracket. The bracket here is provided with holes for rotatably connecting to the shafts at both ends of the X-plate group.

[0019] The uppermost X-shaped lifting rod of the X-type lifting bracket 3 is connected to the top platform by sliding and rotating through the bracket.

In fact, it is another shaft at both ends of the X-plate group that is fixed and rotatably connected to the base through the bracket. The bracket here is provided with holes for rotatably connecting to the shafts at both ends of the X-plate group.

[0021] The two identical X-shaped lifting rods are rotatably connected by a shared shaft at both ends of the X-plate assembly.

[0022] This utility model discloses a lifting device for construction engineering with a stabilizing mechanism, comprising a stabilizing mechanism 2. The stabilizing mechanism 2 includes a dual-output shaft motor 201, a threaded shaft 202, a threaded sleeve 203, a movable frame 204, a guide block 205, and a universal ball 206. The dual-output shaft motor 201 is fixedly connected to the bottom surface of the base. Two threaded shafts 202 are provided, and the two threaded shafts 202 are respectively fixedly connected to the two output shafts of the dual-output shaft motor 201. Two threaded sleeves 203 are provided, and the two threaded sleeves 203 are respectively threadedly sleeved on the outside of the two threaded shafts 202. Two movable frames 204 are provided, and the two movable frames 204 are respectively fixedly connected to the ends of the two threaded sleeves 203 away from the dual-output shaft motor 201. A guide block 205 is fixedly connected to the top surface of each movable frame 204. A sliding groove is provided on the bottom surface of the base, and the two guide blocks 205 are slidably connected in the sliding groove. A universal ball 206 is rollably connected to the bottom surface of each guide block 205, and the lower end of the universal ball 206 is rollably connected to the ground.

[0023] The dual-output shaft motor 201 is started, which drives the threaded shaft 202 to rotate. The threaded shaft 202 drives the threaded sleeve 203 to extend to both sides. The threaded sleeve 203 drives the movable frame 204 to move. The universal ball 206 rolls and connects to the ground to achieve stable movement of the movable frame 204. The guide block 205 restricts the rotation of the movable frame 204 driven by the threaded sleeve 203, thereby providing stable rotation for the movement of the movable frame 204. The movement of the movable frame 204 achieves multi-point stable contact between the base and the ground, thereby improving the stability of the device.

[0024] The stabilizing mechanism 2 includes a hydraulic rod 207, a push plate 208, a vertical rod 209, and a friction pad 210. Each movable frame 204 has a hydraulic rod 207 fixedly connected inside, with the piston rod of the hydraulic rod 207 facing downwards. A push plate 208 is fixedly connected to the end of the piston rod of each hydraulic rod 207. A vertical rod 209 is fixedly connected to the bottom surface of each push plate 208. A friction pad 210 is fixedly connected to the bottom surface of each vertical rod 209. Each movable frame 204 has a hole for the vertical rod 209 to pass through. Multiple vertical rods 209 are fixedly connected to the bottom surface of each push plate 208. A friction pad 210 is fixedly connected to the bottom surface of each of the multiple vertical rods 209. Each movable frame 204 has holes for the multiple vertical rods 209 to pass through.

[0025] The hydraulic rod 207 is activated, which drives the push plate 208 to move downward. The push plate 208 drives the vertical rod 209 to move downward. The vertical rod 209 passes through the hole provided above and makes the friction pad 210 contact the ground, thereby increasing the contact area between the device and the ground and improving the stability of the device.

[0026] In this utility model, the top platform has a rectangular cross-section. A guardrail 4 is fixedly connected to the top surface of the top platform. The guardrail 4 surrounds three sides of the top platform. On the left and right sides of the guardrail 4 that do not surround the sides of the top platform, there are multiple blocking blocks 6 in a vertical direction. The multiple blocking blocks 6 are slidably connected to baffles 5 in a vertical direction. A guide frame 7 is fixedly connected to the top surface of the top platform. One end of the uppermost X-shaped lifting rod of the X-shaped lifting bracket 3 is slidably and rotatably connected to the guide frame 7. An L-shaped rod 8 is fixedly connected to the X-shaped lifting rod that is slidably and rotatably connected to the guide frame 7. The L-shaped rod 8 includes two support rods. One of the two support rods of the L-shaped rod 8 is fixedly connected to the X-shaped lifting rod. The guide frame 7 has a hole. The support rod that is fixedly connected to the X-shaped lifting rod is slidably connected to the hole in the guide frame 7. An insertion rod 9 is fixedly connected to the other support rod of the L-shaped rod 8. The lower part of the baffle 5 has an insertion hole. The end of the insertion rod 9 away from the L-shaped rod 8 is inserted into the insertion hole in the lower part of the baffle 5.

[0027] The top platform provides a workspace for staff. Guardrail 4 serves a protective purpose. Guardrail 4 does not surround the sides of the top platform to facilitate staff getting on and off the platform. Baffle 5 covers the sides of the top platform to provide protection. It should be noted that staff should only get on and off the top platform when it is at its lowest point.

[0028] In this embodiment, the L-shaped rod 8 is connected to a shaft at both ends of the X-plate assembly.

[0029] The height adjustment of the lifting vehicle 1 is achieved by the opening and closing of multiple X-shaped lifting rods in the X-shaped lifting bracket 3. When the lifting vehicle 1 is raised, the distance between the two ends of the two X-plates in the X-shaped lifting rod is reduced. That is, when the lifting vehicle 1 is raised, the L-shaped rod 8 moves towards the center of the X-shaped lifting bracket 3. Therefore, the L-shaped rod 8 can drive the insert rod 9 to be inserted into the insertion hole at the lower part of the baffle 5. This ensures that when the lifting vehicle 1 is raised, the baffle 5 is limited and controlled by the insert rod 9 and cannot be removed. The baffle 5 can only be removed after the insert rod 9 is disengaged from the insertion hole at the lower part of the baffle 5 when the top platform is at its lowest point. This further ensures the safety of this utility model.
