Description

Technical Field

[0001] This utility model belongs to the field of cement pole mold hoisting technology, specifically relating to a cement pole mold hoisting tool. Background Technology

[0002] Cement poles are overhead power line supports, primarily constructed from steel reinforcement and concrete. They are manufactured using steel molds, pouring equipment, and molding devices.

[0003] During the fabrication of cement poles, a reinforcing cage is placed inside a steel formwork, and then concrete is poured into the formwork using a pouring device. The formwork is then transferred to a centrifugal forming device, and finally, it is hoisted into curing equipment for further curing. All of these processes require hoisting equipment to lift and move the steel formwork.

[0004] In the prior art, such as the utility model with patent publication number CN205419616U, a lifting device for steel formwork of utility poles is disclosed. The lifting device includes a base, a connecting seat, a motor, a drive wheel, a steel rope, and lifting clamps. The base includes two interconnected supports. The connecting end formed by the interconnection of the two supports is located inside the connecting seat. A limiting device is provided at the center of the connecting seat. Locking devices are fixedly installed at the connection points between the connecting seat and the supports at both ends. A drive wheel is provided at the lower end of the connecting seat. A motor is provided between the connecting seat and the drive wheel. The drive wheel is connected to the connecting seat through a support rod. Corresponding lifting clamps are provided at the lower ends of both sides of the base. The lifting clamps are connected to the drive wheel through a steel rope.

[0005] While the aforementioned utility model provides a stable lifting device structure and convenient operation, it is relatively general in its design. It does not disclose the connection between the motor and the drive wheel, the lifting clamp, or how the rotation of the drive wheel simultaneously extends and retracts the steel cables at both ends. Furthermore, the inclusion of both a drive motor and a drive wheel results in high overall device manufacturing costs. Therefore, a simpler, lower-cost cement pole mold lifting device needs to be designed. Utility Model Content

[0006] This utility model provides a cement pole mold lifting tool to solve the technical problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A cement pole mold lifting device includes: a lifting base; and clamps. The clamps are disposed on the bottom surfaces of both ends of the lifting base. The clamps include a first rod body, a second rod body, a third rod body, an L-shaped rod, a first connecting rod, a second connecting rod, and a third connecting rod. One end of the first rod body is vertically connected to the lifting base, and the other end is connected to the middle of the first connecting rod. Both ends of the first connecting rod are hinged to one end of the second rod body. Both ends of the second connecting rod are hinged to the end of the second rod body away from the first connecting rod and the end of the third rod body, respectively. The end of the third rod body away from the second connecting rod is connected to the vertical end of the L-shaped rod. Both ends of the third connecting rod are hinged to the middle of the third rod body.

[0009] As a further improvement to the technical solution, every two second rods, the third rods, and the L-shaped rods are set as a group; at least one group of second rods is provided at one end of the first connecting rod; at least one group of third rods is provided at one end of the second connecting rod and the third connecting rod; the second rods and the third rods in the same group intersect each other; the horizontal ends of the L-shaped rods in the same group face each other.

[0010] As a further improvement to the technical solution, the length directions of the first connecting rod, the second connecting rod, and the third connecting rod are consistent; the length direction of the first connecting rod is perpendicular to the second rod body; and the length directions of the second connecting rod and the third connecting rod are perpendicular to the third rod body.

[0011] As a further improvement to the technical solution, the length directions of the first connecting rod, the second connecting rod, and the third connecting rod are perpendicular to the length direction of the hanging seat.

[0012] As a further improvement to the technical solution, the horizontal end of the L-shaped rod is aligned with the length direction of the hanging bracket.

[0013] As a further improvement to the technical solution, the lifting seat includes a base and a connecting seat; both ends of the base are vertically connected to the end of the first rod away from the first connecting rod; the connecting seat is provided in the middle of the top surface of the base; the connecting seat is connected to the lifting equipment.

[0014] As a further improvement to the technical solution, lifting rings are provided at the four corners of the top surface of the connecting seat; the connecting seat is connected to the lifting equipment through the lifting rings.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] In use, the lifting platform is connected to the lifting equipment, and the lifting equipment is connected to the lifting rings at the four corners of the connecting seat. In its natural state, under the influence of gravity, the second, third, and L-shaped poles in the same group move closer together, and the distance between the L-shaped poles and the first pole increases, with the horizontal ends of the L-shaped poles approaching each other. The lifting equipment lowers the lifting platform, bringing the platform and lifting device closer to the pole formwork. The operator then operates the lifting device to shorten the distance between the L-shaped poles and the first pole, opening the horizontal ends of the L-shaped poles so that their horizontal ends move away from each other. Simultaneously, the horizontal ends of the L-shaped poles are inserted into the gap between the running wheels and the outer surface of the pole formwork. The lifting equipment raises the lifting device, at which point the distance between the L-shaped poles and the first pole increases again, and the horizontal ends of the L-shaped poles approach each other, clamping the pole formwork. As the L-shaped poles rise, they lift the pole formwork. The overall structure is simple, requires no drive motor, and has low manufacturing costs. Attached Figure Description
