Abstract
Description
Technical Field
[0001] This utility model relates to the field of construction equipment technology, and in particular to a pipe hoisting device for narrow spaces. Background Technology
[0002] A space frame is a spatial structure composed of multiple members connected at nodes in a specific grid pattern. In building construction, the hoisting of pipes within confined spaces such as space frame structures is a significant and challenging task in construction management. Current technologies using ordinary machinery for hoisting have the following drawbacks:
[0003] When using a crane for hoisting, the crane boom cannot be too long due to the height of the space frame structure and the narrow space. Otherwise, it will be unable to rotate in the narrow space. In addition, the crane's transfer distance is very limited, making crane hoisting inconvenient. If a gantry crane is used for hoisting, for a long space frame structure, the entire gantry crane needs to be moved from one end of the space frame structure to the other. The entire movement process consumes a lot of energy, so the operating cost is high.
[0004] Therefore, in order to solve the problems of inconvenient lifting operation, high energy consumption and high operating cost when using ordinary machinery for hoisting in narrow spaces such as space frame structures in the prior art, this application proposes a pipe hoisting device for narrow spaces. Utility Model Content
[0005] The purpose of this utility model is to at least solve one of the technical defects described in the background art.
[0006] Therefore, one objective of this utility model is to propose a pipe hoisting device for narrow spaces, which aims to solve the problems of inconvenience, high energy consumption, and high operating costs of ordinary machinery in narrow spaces such as grid structures when hoisting pipes.
[0007] To achieve the above objectives, one embodiment of the present invention provides a pipe hoisting device for narrow spaces, including multiple I-beams and a double-hook electric hoist slidably mounted on the I-beams. The top of the I-beams is fixedly connected to a lifting lug, a lifting strap is fitted on the lifting lug, and U-shaped buckles are inserted into both ends of the lifting strap. Limiting plates are fitted into both ends of the U-shaped buckles, and positioning nuts are threaded to both ends of the U-shaped buckles.
[0008] Both ends of the top of the I-beam are fixedly connected to positioning frames, and connecting rods are fixedly installed inside the positioning frames;
[0009] The two hooks of the double-hook electric hoist are each fitted with a strap.
[0010] The beneficial effects are as follows: First, the I-beams can be fixedly installed on the crossbeams of the space frame structure by slings, and the double-hook electric hoists are installed on the I-beams. Thus, the double-hook electric hoists can be hoisted by binding a pair of pipes, which is simple to operate. Moreover, the moving structure consists only of the double-hook electric hoists and pipes, resulting in low energy consumption and low operating costs. Second, by installing the connecting rods in the positioning frame, multiple I-beams can be connected end to end. Therefore, the corresponding number of I-beams can be assembled according to the length of the space frame structure, which provides high flexibility.
[0011] Preferably, of any of the above solutions, a second strap is movably mounted on the first strap, and both ends of the second strap are fixedly connected to U-shaped hooks.
[0012] The beneficial effects are as follows: the first binding strap is wrapped around the upper surface of the pipe, the second binding strap passes through the bottom of the pipe, and then both ends are hooked onto the first binding strap through U-shaped hooks. When the pipe is lifted, the weight of the pipe presses down on the second binding strap, and the second binding strap pulls down the first binding strap. Thus, the second binding strap and the first binding strap can tightly clamp the pipe, thereby ensuring the stability during the lifting of the pipe. Moreover, the structure is simple and easy to operate.
[0013] Preferably, in any of the above embodiments, an insulating plate is fixedly installed on the side of the I-beam, a conductive plate is fixedly connected to the side of the insulating plate, an insulating bracket is fixedly connected to the double-hook electric hoist, a conductive rod is slidably connected inside the insulating bracket, a contact plate is fixedly connected to one end of the conductive rod near the conductive plate, a spring is provided between the contact plate and the insulating bracket, a connecting rod is fixedly connected to one end of the conductive rod, a clamping nut is threaded onto the outer surface of the connecting rod, grooves are provided at both ends of the conductive plate, an insulating plate is fixedly installed between two adjacent insulating plates, and a grounding plate is fixedly connected to the top and bottom of the insulating plate.
[0014] The beneficial effect is that it makes the power supply lines for the double-hook electric hoist neat and tidy.
[0015] Preferably, in the above scheme, a graphite carbon plate is fixedly installed on the side of the contact plate near the conductive plate.
[0016] The beneficial effects are as follows: the wear resistance of graphite carbon plates is relatively poor compared to that of conductive plates. Therefore, during long-term use, the graphite carbon plates will be damaged due to friction with the conductive plates, but the conductive plates will not be damaged. Therefore, only the graphite carbon plates need to be replaced in the future, which can reduce maintenance costs.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0029] This utility model provides a pipe hoisting device for narrow spaces.
[0030] Example 1:
[0031] like Figure 1-4 As shown, it includes multiple I-beams 1, with positioning frames 16 fixedly connected to both ends of the top of each I-beam 1. Connecting rods 17 are fixedly installed inside the positioning frames 16. The positioning frames 16 have through holes, and the connecting rods 17 have threaded holes. Bolts are threaded through the through holes and into the threaded holes of the connecting rods 17, thus fixing the connecting rods 17 inside the positioning frames 16. The connecting rods 17 connect adjacent I-beams 1 end-to-end, allowing for the assembly of a corresponding number of I-beams 1 according to the length of the space frame, and enabling sliding installation. The double-hook electric hoist 2 is mounted on the I-beam 1. The top of the I-beam 1 is fixedly connected to the lifting lug 11, and the lifting lug 11 is fitted with a lifting strap 12. After the lifting strap 12 is wrapped around the crossbeam on the space frame structure, the U-shaped buckle 13 is inserted into both ends of the lifting strap 12, so that the I-beam 1 can be suspended on the space frame structure. Then, the limiting plate 14 is fitted on both ends of the U-shaped buckle 13, and the positioning nut 15 is threaded to both ends of the U-shaped buckle 13, so that the U-shaped buckle 13 cannot be detached from both ends of the lifting strap 12, thus fixing the I-beam 1 and preventing it from falling.
[0032] The double-hook electric hoist 2 has straps 21 on both hooks. The straps 21 are used to bind the pipe 5. Then, the double-hook electric hoist 2 lifts the pipe 5 and moves the double-hook electric hoist 2 along the I-beam 1, thus achieving the purpose of lifting the pipe 5.
[0033] Preferred, such as Figure 1 and Figure 4As shown, a second strap 22 is movably installed on the first strap 21. Both ends of the second strap 22 are fixedly connected to U-shaped hooks 23. By lowering the first strap 21, the bottom of the first strap 21 is wrapped around the upper surface of the pipe 5. The second strap 22 passes under the pipe 5, and then the U-shaped hooks 23 at both ends of the second strap 22 are hooked on the first strap 21. The ends of the U-shaped hooks 23 are bent to prevent them from slipping off the first strap 21. Finally, the double-hook electric hoist 2 lifts the pipe 5 for transportation. In this fixing method, due to the gravity of the pipe 5, the second strap 22 pulls down the first strap 21 through the U-shaped hooks 23, so that the first strap 21 presses down and the second strap 22 can clamp the pipe 5, thereby preventing the pipe 5 from slipping during hoisting.
[0034] The working principle of this utility model is as follows: In use, the I-beam 1 is fixed to the crossbeam of the grid structure by the sling 12. Two adjacent I-beams 1 are fixed together by the connecting rod 17. The double-hook electric hoist 2 is inserted from one end of the I-beam 1 and the power is turned on. The double-hook electric hoist 2 can then travel on the track composed of multiple I-beams 17. When hoisting the pipe 5, the double-hook electric hoist 2 lowers the hook so that the binding strap 1 21 on the hook falls on the upper surface of the pipe 5. One end of the binding strap 22 passes through the bottom of the pipe 5. Then, the two U-shaped hooks 23 at both ends of the binding strap 22 are hung on the binding strap 1 21. The double-hook electric hoist 2 lifts the pipe 5. The weight of the pipe 5 presses down on the binding strap 22. The binding strap 22 pulls down the binding strap 21 through the U-shaped hooks 23, so that the binding strap 1 21 and the binding strap 22 tightly clamp the pipe 5, thereby stably lifting the pipe 5. Then, the double-hook electric hoist 2 is moved to hoist the pipe 5 to the destination.
[0035] Example 2:
[0036] like Figure 1 and Figure 5 As shown, based on Embodiment 1, an insulating plate 3 is fixedly installed on the side of the I-beam 1. Both the I-beam 1 and the insulating plate 3 have through holes on their sides. Bolts are inserted through these through holes, and nuts are then attached to the bolt surfaces to fix the insulating plate 3 to the side of the I-beam 1. A conductive plate 31 is fixedly connected to the side of the insulating plate 3. The conductive plate 31 is connected to a power source via a cable. Figure 4As shown, an insulating bracket 24 is fixedly connected to the double-hook electric hoist 2. A conductive rod 25 is slidably connected inside the insulating bracket 24. A contact plate 26 is fixedly connected to one end of the conductive rod 25 near the conductive plate 31. A spring 27 is provided between the contact plate 26 and the insulating bracket 24. The spring 27 pushes the contact plate 26, causing the conductive rod 25 to slide within the insulating bracket 24. When the contact plate 26 contacts the conductive plate 31, electrical energy can be conducted to the conductive rod 25. A receiving rod 28 is fixedly connected to one end of the conductive rod 25. The power supply line of the double-hook electric hoist 2 is wound around the surface of the receiving rod 28. A clamping nut 29 is threaded onto the outer surface of the receiving rod 28 to fix the power supply line of the double-hook electric hoist 2, thus achieving the purpose of powering the double-hook electric hoist 2. Please refer to [link to relevant documentation]. Figure 3 , Figure 5 and Figure 6 The conductive plate 31 has grooves 32 at both ends. An insulating plate 33 is fixedly installed between two adjacent insulating plates 31. A grounding plate 34 is fixedly connected to the top and bottom of the insulating plate 33. The grounding plate 34 connects the two adjacent conductive plates 31 together, thereby ensuring that the double hook electric hoist 2 can be powered continuously when it moves from one I-beam 1 to another I-beam 1. This design makes the power supply line of the double hook electric hoist 2 neat and tidy.
[0037] Example 3:
[0038] like Figure 7 As shown, based on Embodiment 1 or Embodiment 2, a graphite carbon plate 4 is fixedly installed on the side of the contact plate 26 near the conductive plate 31. The wear resistance of the graphite carbon plate 4 is relatively poor compared to that of the conductive plate 31. Therefore, during long-term use, the graphite carbon plate 4 will be damaged due to friction with the conductive plate 31, while the conductive plate 31 will not be damaged. Therefore, only the graphite carbon plate 4 needs to be replaced in the future, which can reduce maintenance costs.
[0039] Specifically, a positioning plate 41 is fixedly connected to one side of the graphite carbon plate 4. The positioning plate 41 has a through hole, and the side of the contact plate 26 has a threaded hole. By using a bolt to pass through the through hole and threaded into the threaded hole, the graphite carbon plate 4 can be fixedly installed on the contact plate 26. A limiting groove 261 is provided on one side of the contact plate 26. A part of the graphite carbon plate 4 is stuck in the limiting groove 261, so that the graphite carbon plate 4 will not slide up and down, thereby reducing the force on the bolt fixing the graphite carbon plate 4.
