Description

Technical Field

[0001] The utility model relates to the technical field of tensioning jacks, in particular to a tensioning jack lifting device. Background Art

[0002] Tension jack is a special jack used for tensioning prestressed tendons such as steel strands. Tension jacks need to be used in conjunction with tension oil pumps. The power for tensioning and jacking back is provided by the high-pressure oil of the tension oil pump. According to the different structures, they are divided into front card type jacks and through-type jacks. Tension jacks have compact structures, stable operation during tensioning, high oil pressure, and large tensioning force. They are widely used in prestressed construction projects such as highway bridges, railway bridges, hydropower dams, and high-rise buildings.

[0003] At present, some lifting equipment requires manual adjustment to raise and lower the tensioning jack. Although this can save costs, it is too cumbersome for operators to operate. Secondly, the disassembly of most lifting equipment is also cumbersome, which reduces the work efficiency and convenience of construction. In addition, the lifting of the lifting equipment is mostly connected to the tensioning oil pump by an iron chain, and the existing iron chain is only one, which will weaken the reliability of the lifting support. Utility Model Content

[0004] The purpose of the utility model is to provide a tensioning jack lifting device, which solves the technical problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a tensioning jack lifting device, comprising an equipment moving frame, a motor frame is fixedly installed on the upper surface of the equipment moving frame, a motor is fixedly installed inside the motor frame, an output shaft of the motor is fixedly connected to a gear, the teeth of the gear are meshed and connected to a toothed plate for lifting, both end surfaces of the toothed plate are fixedly connected to a limit plate, a clamping connecting plate is connected below the limit plate, two groups of symmetrical upper connecting rings and lower connecting rings are fixedly connected to the relative surfaces of the clamping connecting plate and the limit plate located at the lower end, the upper connecting ring and the lower connecting ring are both buckled with shackle lifting rings, an iron chain is buckled between the shackle lifting rings on the same side, a tension oil pump is clamped and connected inside the clamping connecting plate, a plurality of second bolts are threadedly connected between the clamping connecting plate and the connecting frame of the tension oil pump, and a jack is fixedly installed inside the tension oil pump.

[0006] Optionally, a first bolt is threadedly connected between the equipment moving frame and the motor frame.

[0007] Optionally, a group of symmetrical clamping plates are fixedly connected to the two side surfaces of the tooth plate close to the teeth, and the inner surfaces of the clamping plates fit and slide on the two side surfaces of the gear.

[0008] Optionally, a special-shaped sliding groove is formed through the top surface of the equipment moving frame for the tooth plate and the clamping plate to slide.

[0009] Optionally, a group of symmetrical sliding grooves are opened on the inner surfaces of both sides of the equipment moving frame, and sliding rods are slidably connected in the sliding grooves, and the sliding rods are fixedly connected to the two side surfaces of the limiting plate located at the lower end.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] 1. The utility model adopts a design in which a motor drives the gear to drive the tooth plate to lift, so that the operator only needs to start the motor to let the output end of the motor drive the gear to rotate. When the gear engages the tooth plate, the tension oil pump and the jack reach the required lifting height, avoiding the tedious manual operation of the operator, and the structure is simple and high, which helps to improve the working efficiency and convenience of the lifting equipment.

[0013] 2. The utility model connects the upper connecting ring and the lower connecting ring through the limit plate and the clamping connecting plate. First, when the operator installs before use, he can first use the shackle lifting ring to buckle them on the upper connecting ring and the lower connecting ring in sequence, and then clamp the clamping connecting plate on the external connecting frame of the tension oil pump, and through the second bolt, the clamping connecting plate and the tension oil pump are firmly connected, and the second bolt is provided in multiple threaded grooves of the clamping connecting plate, so that it can be matched with jacks of different sizes. The disassembly and assembly process is simple and reliable, thereby further improving the working efficiency and convenience of the lifting equipment.

[0014] 3. The utility model uses two symmetrical iron chains connected between the upper connecting ring and the lower connecting ring, so that the lifting driving force for the tension oil pump and the jack is not limited to one point, but is dispersed into two points with better balanced force, thereby improving the supporting reliability of the lifting equipment.

Shackle rings 14 are buckled in the upper connecting rings 11 and the lower connecting rings 13, and iron chains 15 are buckled between the shackle rings 14 on the same side. A tension oil pump 16 is clamped and connected in the clamping connecting plate 12, and a plurality of second bolts 18 are threadedly connected between the clamping connecting plate 12 and the connecting frame of the tension oil pump 16, and a jack 17 is fixedly installed inside the tension oil pump 16.

[0024] More specifically, in this embodiment, first, when the operator performs installation before use, he can first install the motor frame 3 on the equipment moving frame 1 through the first bolt 4, and then use the shackle lifting ring 14 to buckle it on the upper connecting ring 11 and the lower connecting ring 13 in sequence, and then clamp the clamping connecting plate 12 on the external connecting frame of the tension oil pump 16, and use the second bolt 18 to firmly connect the clamping connecting plate 12 and the tension oil pump 16, and the second bolt 18 is provided with a plurality of threaded grooves of the clamping connecting plate 12, so that it can be matched with jacks 17 of different sizes, and its disassembly and assembly process is simple and reliable, thereby improving the working efficiency and convenience of the lifting equipment, and the operator only needs to start the motor 5 to allow the output end of the motor 5 to drive the gear 6 to rotate, and the gear 6 engages the tooth plate 7 at the same time, so that the tension oil pump 16 and the jack 17 reach the required lifting height, avoiding the tedious manual operation of the operator, and the structure is simple and high, which helps to improve the working efficiency and convenience of the lifting equipment.

[0025] By connecting the upper connecting ring 11 and the lower connecting ring 13 with two symmetrical iron chains 15, the lifting and lowering driving force of the tension oil pump 16 and the jack 17 is not limited to one point, but is dispersed into two points with better balanced force, thereby improving the supporting reliability of the lifting equipment.
