Description

Technical Field

[0001] This utility model relates to the field of equipment installation technology, specifically to a parallel slide device for installing a cooler in a confined space. Background Technology

[0002] In industries such as power, metallurgy, and chemicals, the installation and replacement of heavy equipment (such as coolers and heat exchangers) in confined spaces is a routine operational requirement. These scenarios typically face challenges such as limited space height, dense obstacles, and the inability of large hoisting equipment to access the site. Especially during the renovation of old factories or emergency repairs, traditional methods struggle to balance safety and efficiency, necessitating a versatile and adaptable installation technology solution.

[0003] The replacement of a 700 kg cooler at a waste heat power generation station faces multiple safety hazards, including the risk of accidental energy release. The work area is confined, with fixed pillars obstructing the view of the cooler, and dense equipment surrounding the enclosure, leaving insufficient operating space. Improper operation could easily lead to equipment collisions and accidental energy release. The 1-meter lifting height limit prevents the use of conventional lifting equipment, and forklifts and trolleys are difficult to access due to equipment layout. Traditional replacement methods require shutdown, impacting power generation efficiency and making multi-person collaborative handling difficult due to weight constraints. Furthermore, human error during the process could cause equipment damage and personnel injury, severely hindering maintenance progress and operational safety. Utility Model Content

The sliding assembly includes a lifting element 5 mounted on the support frame 1 and a sliding element 6 slidably mounted on the support rod 2. The lifting element 5 is detachably connected to the support rod 2. A support element 7 is movably mounted on the sliding element 6. A lifting element 8 is provided between the sliding element 6 and the support element 7. The external cooler 9 is located on the support element 7. Under the action of external force, the lifting element 5 drives the support rod 2 to move up or down along the support frame 1, thereby driving the cooler 9 to move up or down to coarsely adjust the height of the cooler 9. Under the action of external force, the lifting element 8 rotates, thereby driving the support element 7 to move up or down to finely adjust the height of the cooler 9. Under the action of external force, the sliding element 6 moves along the support rod 2, thereby adjusting the position of the cooler 9 on the horizontal plane.

[0018] Further, see Figure 1 , 2 The support frame 1 includes multiple sets of support columns 101 and connecting crossbars 102 that are detachably connected to the multiple sets of support columns 101. Support crossbars 103 are detachably provided between the connecting crossbars 102.

[0019] Preferably, both the support column 101 and the support crossbar 103 are made of square steel pipes, and the bottom end of the support column 101 is welded with a support base plate 104 to increase the contact area with the ground.

[0020] Preferably, four sets of support columns 101 and support crossbars 103 are provided.

[0021] Preferably, connecting lugs 10 are welded at intervals to the top of the support column 101 and the middle of the two sets of oppositely arranged connecting crossbars 102. Connecting holes 11 are provided at the ends of the connecting lugs 10, the connecting crossbars 102, and the support crossbars 103. The support column 101 and the connecting crossbars 102 are connected by bolts passing through the connecting holes 11 on the connecting lugs 10 and the connecting crossbars 102. The connecting crossbars 102 and the support crossbars 103 are connected by bolts passing through the connecting holes 11 on the connecting lugs 10 and the support crossbars 103.

[0022] Further, see Figure 1 , 2 Limiting plates 12 are provided at intervals on the support column 101, and limiting space 13 is formed between the limiting plates 12. The two ends of the support rod 2 are movable within the limiting space 13.

[0023] Preferably, the limiting plate 12 is welded to the outer wall of the support column 101, and two sets of limiting plates 12 are welded to each set of support columns 101.

[0024] Further, see Figure 1 ,2 The locking component 4 includes locking holes 401 spaced apart on the limiting plate 12 and fixing holes 402 on the end of the support rod 2. A locking rod 403 is detachably provided between the locking holes 401 and the fixing holes 402. The locking rod 403 passes through the locking holes 401 and the fixing holes 402 to fix the position between the support rod 2 and the limiting plate 12.

[0025] Preferably, the locking holes 401 are spaced apart along the axial direction of the limiting plate 12, and the locking holes 401 are correspondingly arranged with the fixing holes 402. The outer diameter of the locking rod 403 is smaller than the inner diameter of the locking holes 401 and the fixing holes 402, so that after the support rod 2 moves along the limiting space 13, the locking rod 403 can still be inserted when there is a small alignment deviation between the locking holes 401 and the fixing holes 402, thereby fixing the position of the support rod 2 relative to the limiting plate 12, that is, fixing the support rod 2 on the support frame 1.

[0026] Further, see Figure 1 , 2 The lifting component 5 includes a detachable lifting device 501 mounted on the support crossbar 103 and a lifting steel rope 502 connected to the lifting device 501. The ends of the lifting steel rope 502 are detachably connected to the ends of the support rod 2.

[0027] Preferably, the lifting equipment 501 can be a hand-operated hoist, an electric hoist, etc. The lifting equipment 501 is connected to the support crossbar 103 by bolts. The lifting steel rope 502 consists of two steel ropes that cross each other and are connected and fixed in the middle by a wire rope clamp (existing structure), ensuring that the four sets of ends of the two steel ropes are flush. The middle of the two steel ropes is connected to the hook of the lifting equipment 501, such as the hand-operated hoist.

[0028] Preferred, see Figure 2 , 3 The support rod 2 has a lifting lug 14 welded to its end. The four ends of the two steel ropes are bent into loops by wire rope clamps and connected with hooks. The hooks are detachably connected to the lifting lug 14.

[0029] In the above setup, by controlling the hand chain hoist to move the hook up or down, the support rod 2 can be moved up or down within the limiting space 13 to make a coarse adjustment to the height of the cooler 9. After the adjustment is completed, the locking rod 403 is inserted into the locking hole 401 and the fixing hole 402 to fix the position of the support rod 2 on the support frame 1.

[0030] Further, see Figure 1 , 2 4. The sliding component 6 includes a sliding rod 601 slidably disposed on the support rod 2, and sliding blocks 602 are provided at both ends of the sliding rod 601 and are slidably connected to the support rod 2.

[0031] Preferably, the support rod 2 is provided with a groove 15 along the axial direction, and the sliding block 602 is located in the groove 15, thereby connecting the two sets of support rods 2 through the sliding rod 601.

[0032] Further, see Figure 1 , 2 4. The support member 7 includes a support rod 701 slidably mounted on the sliding rod 601 and a support plate 702 mounted on the support rod 701. The support plate 702 is provided with a groove 703 to support the cooler 9.

[0033] Preferably, two sets of support rods 701 are provided at intervals, and two sets of sliding holes 16 are provided on the sliding rod 601 at intervals to cooperate with the support rods 701. The inner diameter of the sliding hole 16 is larger than the outer diameter of the support rod 2.

[0034] Further, see Figure 1 , 2 4. The lifting component 8 includes a lifting worm wheel 801 that is threadedly engaged with the support rod 701 and a lifting worm 802 that meshes with the lifting worm wheel 801. The lifting worm wheel 801 is rotatably connected to the sliding rod 601. A transmission rod 803 is provided on the lifting worm 802 and is rotatably mounted on the sliding rod 601.

[0035] Preferably, a connecting sleeve 17 is welded to the sliding hole 16, and a first bearing 18 is provided on the connecting sleeve 17. The inner ring of the first bearing 18 is fixedly connected to the connecting sleeve 17, and the inner diameter of the connecting sleeve 17 is the same as the inner diameter of the sliding hole 16.

[0036] Preferred, see Figure 5 The center of the lifting worm gear 801 is provided with a threaded hole 19 that is threaded to the outer wall of the support rod 701. The inner diameter of the threaded hole 19 is smaller than the inner diameter of the sliding hole 16. A fixing sleeve 20 is welded concentrically to the threaded hole 19 on the lifting worm gear 801. The inner wall of the fixing sleeve 20 is fixedly connected to the outer ring of the first bearing 18.

[0037] Preferably, the sliding rod 601 is provided with two sets of support plates 21 at intervals, the support plates 21 are provided with a second bearing 22, the transmission rod 803 is fixedly connected to the inner ring of the second bearing 22, and the transmission rod 803 is provided with a handle 23.

[0038] In the above setup, after the cooler 9 located on the support plate 702 is roughly adjusted in height by the lifting device 501, the sliding rod 601 is pushed to move in the slide groove 15, thereby adjusting the position of the cooler 9 on the horizontal plane. The cooler 9 can be pushed to the installation point. Then, the handle 23 is rotated to drive the transmission rod 803 to rotate. The lifting worm 802 rotates with the transmission rod 803 and meshes with the lifting worm wheel 801, causing the lifting worm wheel 801 to rotate. Under the action of the thread, the support rod 701 moves up or down, thereby finely adjusting the height of the cooler 9. By adjusting the height and position of the cooler 9 on the horizontal plane, the cooler 9 can be aligned with the installation position, which facilitates the installation and fixing of the cooler 9.

[0039] In this embodiment, the support frame 1 is assembled at the installation site of the cooler 9. The support frame 1 provides support for the entire device. The lifting equipment 501 is connected to the support frame 1. The support rod 2 is installed in the limiting space 13 and connected to the limiting plate 12 through the locking rod 403. The sliding rod 601 is installed on the support rod 2. The lifting equipment 501 is set up outside the support frame 1. With the help of manpower, the new cooler 9 is moved into the groove 703 on the support plate 702. The lifting steel rope 502 is connected to the lifting equipment 501 and the support rod 2 respectively. The locking rod 403 is pulled out, and the support rod 2 is driven by the lifting equipment 501. The cooler 9 is moved upwards to roughly adjust its height. Based on the location of the installation point of the cooler 9, the lifting height of the cooler 9 is determined. Then, the locking rod 403 is inserted into the position of the fixed support rod 2, and the sliding rod 601 is pushed to move along the support rod 2 to adjust the position of the cooler 9 on the horizontal plane so that the cooler 9 is close to the installation point. The rotating handle 23 drives the transmission rod 803 to rotate. Under the meshing of the lifting worm gear 802 and the lifting worm wheel 801, the support plate 702 moves up or down, and in conjunction with pushing the sliding rod 601 to move along the support rod 2, thereby adjusting the alignment of the cooler 9 with the installation point to facilitate the installation of the cooler 9.

[0040] During the installation of cooler 9, collisions with surrounding dense equipment are avoided to prevent damage to the equipment casing and internal components caused by collisions, ensuring the integrity of the equipment. The entire device structure is stable, and the high-strength square steel support column 101 and support rod 2 have reliable load-bearing capacity. The 700 kg cooler 9 remains stable during movement, with no risk of falling or tilting, preventing hard damage caused by structural instability. No high-altitude work or heavy equipment operation is required, avoiding the squeezing and collision of heavy equipment with surrounding equipment. At the same time, direct contact between personnel and equipment is reduced, minimizing the impact of human error on the equipment, ensuring that the equipment is always in a safe state during maintenance, and extending the service life of the equipment.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
