Description

Technical Field

[0001] This utility model relates to the field of pipe hoisting technology, specifically to a beam hoisting device for automatically stabilizing stacked pipes. Background Technology

[0002] During construction, it is necessary to install piping systems within the building. In high-altitude construction sites, pipes are typically lifted directly by hoisting. After packaging and bundling several pipes, a crane or hoist lifts the stacked and packaged pipes to the designated floor, which is less labor-intensive than manually carrying them to high floors.

[0003] In existing technologies, the lifting of several pipe fittings requires bundling and packaging before being lifted and transported by an external crane. Due to the large width of the stacked pipe fittings, a load-bearing beam needs to be installed on top to form a beam-type lifting system during transport. For example, a general-purpose beam-type lifting device is disclosed in CN 221440096 U. This device includes a crossbeam, pulley blocks, an electric hoist, a flexible steel cable, an upper lifting chain assembly, and an electromagnet. This invention addresses this by providing a flexible steel cable connected at both ends to an electric hoist, along with a corresponding pulley block.

[0004] Several stacked pipe fittings are reinforced with fixing ropes. When the crossbeam is lifted by the fixing ropes, a triangular vacuum area is formed between the crossbeam and the fixing ropes. The pipe fittings inside the fixing ropes are reinforced by the forces from the sides and bottom, but the top surface of the topmost pipe fitting is not fixed. If crosswinds or other factors cause the lifting ropes to tilt during hoisting, the hoisted pipe fitting may fall from a height and cause an accident. Summary of the Invention

[0005] The purpose of this invention is to solve the problem that when several stacked pipes are hoisted at high altitudes, the top surface is not fixed, which may lead to accidental falling. Therefore, this invention proposes a beam-type hoisting device that automatically stabilizes the stacked pipes.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] An automatic pressure-stabilizing beam-type hoisting device for stacked pipe components includes several transport pipe components stacked in an array. Two fixing ropes are fitted onto the surface of each transport pipe component, and a pressure-stabilizing structure is provided on the top surface of the two fixing ropes. The pressure-stabilizing structure includes:

[0008] The hoisting beam has recessed positioning grooves on both sides of its surface, and the fixing rope is looped in the corresponding positioning groove.

[0009] The sliding groove is located on both sides of the bottom surface of the hoisting beam. The two sliding grooves are on the same horizontal line. A sliding rod is slidably connected inside the sliding groove. A pressing rod is fixedly connected to the bottom surface of the sliding rod. The pressing rod is in contact with the surface of the transport pipe of the top layer below.

[0010] A double-ended lead screw is rotatably connected inside the hoisting beam. A limit block is threadedly connected to the surface of the double-ended lead screw, and a connecting spring is fixedly connected to the bottom surface of the limit block.

[0011] The lifting chute is located on both sides of the sliding chute. Corresponding lifting blocks are provided on both sides of the sliding block. The bottom surface of the lifting block is in close contact with the surface of the lifting chute, and the top surface of the sliding rod is fixedly connected to the connecting spring.

[0012] As a further embodiment of this utility model: the bottom surface of the pressing plate is provided with several arc grooves, the shape of which is adapted to the shape of the transport pipes stacked below.

[0013] As a further embodiment of this utility model: the top ends of the two fixed ropes are connected to hoisting ropes, the top ends of the two hoisting ropes are inclined, and the top ends of the two hoisting ropes are wound together to form a hoisting rope.

[0014] As a further embodiment of this utility model: a motor is provided on one side of the hoisting beam, and the output end of the motor is fixedly connected to one end of the double-headed lead screw.

[0015] As a further embodiment of this utility model: a counterweight is fixedly connected to the other side of the motor on the hoisting beam.

[0016] As a further embodiment of this utility model: the lifting chute is located inside the hoisting beam, and the surfaces of the lifting chute on both sides are inclined downwards along the direction close to the center plane.

[0017] The beneficial effects of this utility model are:

[0018] (1) The present invention provides an automatic pressure-stabilizing beam hoisting device for stacked pipe components. By setting a pressure-stabilizing structure, the hoisting beam of the pressure-stabilizing structure forms a triangular vacuum area with the stacked transport pipe components below during the hoisting process. The hoisting beam drives the sliding rod to slide through the internal double-headed screw. The sliding rod rises and falls during the sliding process, adjusting the height of the pressing rod at the bottom of the sliding rod, so that the pressing rod presses and stabilizes the top layer of the stacked hoisting beam. During the transportation process, the bottom and sides of the stacked transport pipe components are fixed by the fixing rope, and the top surface is stabilized by the pressure of the pressing rod, so that the stacked transport pipe components are stabilized in all directions, preventing them from falling during the high-altitude hoisting process.

[0019] (2) The present invention provides an automatic pressure-stabilizing beam hoisting device for stacking pipe fittings. By setting a sliding groove and a lifting chute, the limiting block inside the hoisting beam is squeezed by the connecting spring during the sliding process, so that the lifting block drives the sliding rod to rise and fall along the inclined surface of the lifting chute, thereby indirectly driving the pressing rod to rise and fall.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-6As shown, this utility model is a beam-type hoisting device for automatically stabilizing stacked pipe fittings, including several transport pipe fittings 1, which are stacked in a rectangular array. Two fixing ropes 2 are fitted onto the outer surface of the array of transport pipe fittings 1, and a stabilizing structure 4 is mounted on the top surface of the two fixing ropes 2. The hoisting beam 41 of the stabilizing structure 4 is located below the two fixing ropes 2. Recessed positioning grooves 42 are provided on both sides of the surface of the hoisting beam 41, and the fixing ropes 2 are positioned within the positioning grooves 42 of the hoisting beam 41. A hoisting rope 3 is formed on the top surface of the annular fixing rope 2 on one side, and the tops of the hoisting ropes 3 on both sides slope towards the middle to form another rope. External hoisting equipment hoists the vertical hoisting rope 3, thereby lifting the fixed pipe fittings below.

[0030] The hoisting equipment lifts the hoisting beam 41, causing the hoisting beam 41 to move the fixing rope 2 and form a triangular vacuum area with the transport pipe 1 below. The bottom surface of the hoisting beam 41 of the stabilizing structure 4 has sliding grooves 43 on both sides, symmetrically arranged about the central plane of the hoisting beam 41. Each sliding groove 43 contains a sliding rod 44. A pressing rod 45 is fixedly connected to the bottom surface of the sliding rods 44 on both sides. The bottom surface of the pressing rod 45 has several continuous arc grooves 46, the shape of which conforms to the shape of several transport pipes 1. The pressing rod 45 can tightly press the transport pipe 1 at the top layer below through the arc grooves 46. A motor 47 is fixedly connected to one side of the hoisting beam 41, with the output end of the motor 47 extending into the sliding groove 43. A counterweight 413 is fixedly connected to the other side of the hoisting beam 41. The counterweight 413 cooperates with the motor 47 to position the center of gravity of the hoisting beam 41 at the central plane. A double-ended lead screw 48 is fixedly connected to the output end of the motor 47, and the double-ended lead screw 48 is slidably connected within the sliding groove 43. Two limiting blocks 49 are sleeved on the surface of the double-ended lead screw 48, and the two limiting blocks 49 are threadedly connected to the surface of the double-ended lead screw 48, and the limiting blocks 49 are slidably limited within the sliding groove 43. A connecting spring 410 is fixedly connected to the bottom surface of the two limiting blocks 49, and a sliding rod 44 is fixedly connected to the bottom surface of the connecting spring 410. A lifting inclined groove 411 is opened inside the hoisting beam 41, and the lifting inclined groove 411 is located on both sides of the sliding groove 43. The bottom surface of the lifting inclined groove 411 is inclined downward along the direction close to the center plane. A lifting block 412 is fixedly connected to both sides of each sliding rod 44. The bottom surface of the lifting block 412 is inclined and contacts the surface of the lifting inclined groove 411.

[0031] When using this automatic pressure-stabilizing pipe stacking beam hoisting device, several transport pipes 1 are stacked in an array. Fixing ropes 2 are then fitted onto both sides of the stacked transport pipes 1, securing the bottom and sides of the pipes. A gap is left between the top ends of the two fixing ropes 2 and the top transport pipe 1, providing hoisting space. A pressure-stabilizing structure 4 is installed at the top of the two fixing ropes 2, and the hoisting beam 41 of the pressure-stabilizing structure 4 is connected to the fixing ropes 2. The top ends of the two fixing ropes 2 form a hoisting rope 3, which is connected to external hoisting equipment. During hoisting, the hoisting beam 41 drives the fixing ropes 2 upward, forming a triangular vacuum area. At this time, the motor 47 on one side of the hoisting beam 41 is activated, and the output of the motor 47 drives the double-ended lead screw 48 to rotate. The limiting blocks 49 on the surface of the double-ended lead screw 48 are subjected to threaded force and limiting action, causing the two limiting blocks 49 to move closer together. The limiting block 49 drives the sliding rod 44 to slide via the connecting spring 410 at its bottom. The connecting spring 410 presses the sliding rod 44 downward, causing the sliding rod 44 to move vertically. The lifting block 412 on the surface of the sliding rod 44 is in close contact with the bottom surface of the lifting chute 411. During the movement of the sliding rod 44, the lifting block 412 will be in close contact with the lifting chute 411, and the sliding rod 44 will move downward under the force of the connecting spring 410. This will cause the pressing rod 45 on the bottom surface of the sliding rod 44 to press and stabilize the top transport pipe 1. The bottom and sides of the arrayed transport pipe 1 are reinforced by the fixing rope 2, and the top surface is pressed and stabilized by the pressing rod 45, thereby stabilizing the transport pipe 1 in all directions during the lifting and hoisting process and preventing the transport pipe 1 from falling from a height during the hoisting process. When disassembly is required, the motor 47 drives the double-headed lead screw 48 to rotate in the opposite direction, thereby lifting the sliding rods 44 on both sides during the sliding process, releasing the pressure on the top transport pipe 1 so that it can be taken out from the fixing rope 2.

[0032] The working principle of this utility model is as follows: This utility model provides an automatic pressure-stabilizing beam-type hoisting device for stacked pipe components. By setting a pressure-stabilizing structure 4, the hoisting beam 41 of the pressure-stabilizing structure 4 forms a triangular vacuum area with the stacked transport pipe components 1 below during hoisting. The hoisting beam 41 drives a sliding rod 44 to slide via an internal double-ended screw 48. The sliding rod 44 rises and falls during sliding, adjusting the height of the pressing rod 45 at the bottom of the sliding rod 44, thereby allowing the pressing rod 45 to press and stabilize the top layer of the stacked hoisting beam 41. During transportation, the bottom and sides of the stacked array of transport pipes 1 are fixed by the fixing ropes 2, and the top surface is stabilized by the pressure of the pressing rod 45, so that the stacked transport pipes 1 are stabilized in all directions to prevent them from falling during high-altitude hoisting. By setting the sliding groove 43 and the lifting inclined groove 411, the limiting block 49 inside the hoisting beam 41 is squeezed by the connecting spring 410 during the sliding process, so that the lifting block 412 drives the sliding rod 44 to rise and fall along the inclined surface of the lifting inclined groove 411, thereby indirectly driving the pressing rod 45 to rise and fall.

All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
