Description
Technical Field
[0001] This utility model relates to the field of highway construction technology, specifically a simple device for lifting and moving heavy jacks. Background Technology
[0002] Beam and slab tensioning refers to the process of prestressing beams or slabs in structural engineering. By applying tension force to the concrete before it hardens, its load-bearing capacity and crack resistance can be improved. This method is particularly suitable for long-span beams or large-area slabs, effectively reducing their self-weight and deformation while improving the overall performance of the structure.
[0003] During the tensioning of beams and slabs or in other locations with prestressed tensioning, two simple tripods and I-beams are usually used as the lifting and moving device for the tensioning jacks. Alternatively, a truck crane can be used to lift and move the jacks. However, this method of lifting and moving the jacks is less safe and has poor adjustment effect on the position of the tensioning jacks. Utility Model Content
[0004] The purpose of this utility model is to provide a simple device for lifting and moving heavy-duty jacks. By setting up a steel frame, I-beam slide bar, pulley, motor cover and hoisting motor, it solves the problem that in the process of beam tensioning or other places with prestressing tensioning, two simple tripods and I-beams are usually used as the lifting and moving device for tensioning jacks, or a truck crane is used to achieve the lifting and moving of jacks. However, the safety of lifting and moving jacks using this method is low and the adjustment effect of the tensioning jack position is poor.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a simple device for lifting and moving heavy-duty jacks, comprising a steel frame, an I-shaped steel slide rod welded to the inner top wall of the steel frame, a pulley being snapped into the inside of the I-shaped steel slide rod, a support seat being rotatably connected to one side of the pulley, a motor cover being welded to the lower surface of the support seat, and a hoisting motor being fixedly installed inside the motor cover.
[0006] Preferably, traction ropes are fixedly installed on both sides of the motor cover, and a handle is fixedly connected to the bottom end of the traction ropes.
[0007] Preferably, the output end of the hoisting motor is fixedly connected to a rope pulley, the inside of the rope pulley is wound with a split hoisting rope, and the bottom end of the split hoisting rope is equipped with a through-type jack.
[0008] Preferably, a steel plate frame is welded to the bottom of the inner wall of the steel frame, and a steel plate is welded to the surface of the steel plate frame.
[0009] Preferably, a tension control box is installed on one side of the upper surface of the steel plate, and a baffle is welded to one side of the inner wall of the steel frame.
[0010] Preferably, lifting rings are welded at the four corners of the upper surface of the steel frame, and steel wire ropes are wound inside the lifting rings, with a lifting ring wound at the other end of the steel wire ropes.
[0011] This utility model provides a simple device for lifting and moving heavy-duty jacks, which has the following features:
[0012] Beneficial effects:
[0013] When in use, this equipment is connected to the lifting ring via a beam yard gantry crane or truck crane and lifted to the end of the beam. Then, the lifting motor for the through-hole jack on the steel plate platform is lifted, and the traction rope is pulled through pulleys to move the lifting motor along the I-beam slide bar. Once it reaches the destination, the anchor plate is installed, the jack is positioned, and the limit plate is installed. The position of the through-hole jack is then finely adjusted up and down using the lifting motor, and the working clamps are in place, allowing beam tensioning to begin. This device has a simple structure, is small, lightweight, and has low manufacturing costs. It allows for fast construction and high installation efficiency, and reduces the risk of equipment falling due to the use of simple supports during lifting, greatly improving safety and flexibility.

When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment proposes a simple device for lifting and moving heavy-duty jacks, including a steel frame 1. An I-shaped steel slide rod 2 is welded to the inner top wall of the steel frame 1. A pulley 3 is snapped into the inside of the I-shaped steel slide rod 2. A support seat 4 is rotatably connected to one side of the pulley 3. A motor cover 5 is welded to the lower surface of the support seat 4. A hoisting motor 6 is fixedly installed inside the motor cover 5. The pulley 3 allows the motor cover 5 to move back and forth inside it, making it easy for personnel to adjust the position of the hoisting motor 6. Anti-detachment plates are fixed to both ends of the I-shaped steel slide rod 2 with bolts to prevent the motor cover 5 from slipping off the hoisting motor 6 during hoisting and causing a safety accident.
[0024] The motor cover 5 is fixedly installed with traction ropes 7 on both sides. The bottom end of the traction ropes 7 is fixedly connected with a handle 8. After the equipment is moved to a suitable position, the motor cover 5 is moved by pulling the handle 8, which makes it easy to adjust.
[0025] The output end of the hoisting motor 6 is fixedly connected to a rope wheel 9. A branch hoisting rope 10 is wound inside the rope wheel 9. A through-type jack 11 is hoisted at the bottom end of the branch hoisting rope 10. By starting the hoisting motor 6, the rope wheel 9 is wound up and down, which drives the through-type jack 11 to adjust the height.
[0026] A steel plate frame 12 is welded to the bottom of the inner wall of the steel frame 1, and a steel plate 13 is welded to the surface of the steel plate frame 12, allowing personnel to perform control operations on the steel plate 13.
[0027] A tension control box 14 is installed on one side of the upper surface of the steel plate 13, and a baffle 15 is welded on one side of the inner wall of the steel frame 1. The tension control box 14 is equipped with a touch screen and a power socket, and its operation is the same as that of commercially available equipment, so it will not be described in detail here. The hoisting motor 6 and the through-hole jack 11 are connected to it, and the hoisting motor 6 and the through-hole jack 11 are controlled through the tension control box 14.
[0028] Lifting rings 16 are welded at the four corners of the upper surface of the steel frame 1. Steel wire ropes 17 are wound inside the lifting rings 16, and lifting rings 18 are wound at the other end of the steel wire ropes 17. The equipment can be lifted and moved by equipment such as gantry cranes, so that the equipment can be moved to a suitable position for tensioning operations. The overall lifting method avoids safety hazards such as parts falling off.
[0029] Specifically, the simple device for lifting and moving heavy-duty jacks works as follows: When in use, the device is connected to the lifting ring 18 via a beam yard gantry crane or truck crane and lifted to the end of the beam. Then, the lifting motor 6 of the through-hole jack 11 on the steel plate 13 platform is lifted. Subsequently, the traction rope 7 is pulled to drive the lifting motor 6 to move on the I-shaped steel slide bar 2 through the pulley 3. After reaching the destination, the device stops, the anchor plate is installed, the jack is in place, the limit plate is installed, and the position of the through-hole jack 11 is slightly adjusted up and down by the lifting motor 6. Once the working clamp is in place, beam tensioning can begin. The device has a simple structure, is small in size, lightweight, and has low manufacturing cost. It has a fast construction progress and high installation efficiency, and reduces the possibility of the device falling due to the use of simple supports during hoisting, greatly improving safety and flexibility.
