[0015] A method for using a subway track-top ventilation duct installation device includes the following steps:

[0016] S1. Suspension Process: Move the support mechanism to the designated hole via the base frame. Orderly wind the existing suspension rope around the outer surface of the take-up roller, simultaneously threading one end of the rope through the gap between the corresponding guide wheel and guide block. Then, according to actual usage requirements, control the activation of the corresponding position moving motor, causing it to rotate the corresponding moving threaded rod. This rotating threaded rod moves the adjusting block to one side of the corresponding hole, allowing one end of the rope to pass through the guide rod and be pulled to the corresponding hole. At this point, by adding or removing extension blocks according to the actual hole position, the rope can be suspended in a largely vertical state. Then, control the activation of the rotation motor, causing it to rotate the corresponding rotating rod, which in turn rotates the corresponding connecting gear. The rotating linkage gear can drive the corresponding two linkage gear rings to rotate, which in turn can drive the corresponding take-up roller to rotate, allowing the take-up roller to release or reel in the rope. At the same time, when only one take-up roller is used, by rotating the limiting worm, the limiting worm and the limiting worm wheel can drive the corresponding threaded tube to rotate. Then, the rotating threaded tube can move and adjust the corresponding locking block to press tightly against the corresponding take-up roller, thereby fixing the position of the unused take-up roller. By rotating the adjusting lifting rod, the rotating lifting rod can drive the linkage gear away from the unused take-up roller through the moving frame, thereby separating the linkage gear from the linkage gear ring on the outer surface of the unused take-up roller. Then, when the rotating motor drives the rotating rod to rotate, the rotating rod and the linkage gear can drive only the linkage gear ring that is still in the meshing state to rotate.

[0017] S2. Protective Measures: By rotating the first adjusting worm, the rotating first adjusting worm, in conjunction with the first adjusting worm wheel, drives the corresponding first adjusting gear to rotate. Then, under the positional constraint of the first adjusting rack, the first adjusting gear, in conjunction with the side block, drives the corresponding extension strip to one side of the corresponding hole. Next, by rotating the second adjusting worm, the rotating second adjusting worm, in conjunction with the second adjusting worm wheel, drives the second adjusting gear to rotate. Then, under the positional constraint of the second adjusting rack, the second adjusting gear, in conjunction with the sliding frame, moves the guide ring to the corresponding hole, allowing the rope to pass through the guide ring. This prevents the rope from deviating at a large angle during use.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0019] (1) In this invention, during use, the support mechanism is moved to the designated hole via the base frame. The existing suspension rope is wound in an orderly manner around the outer surface of the take-up roller. Simultaneously, one end of the rope passes through the gap between the corresponding guide wheel and the guide block. Then, according to actual usage requirements, the corresponding position moving motor is activated, enabling the moving motor to drive the corresponding moving threaded rod to rotate. This allows the rotating moving threaded rod to move the adjusting block to one side of the corresponding hole, allowing one end of the rope to pass through the guide rod and be pulled to the corresponding hole. At this point, by adding or removing extension blocks according to the actual position of the hole, the rope can be suspended in a largely vertical state. Then, by activating the rotating motor, the rotating motor drives the corresponding rotating rod to rotate, which in turn drives the corresponding connecting gear to rotate. This allows the rotating connecting gear to drive the corresponding two connecting gear rings to rotate. The rotating linkage gear ring drives the corresponding take-up roller to rotate, allowing the take-up roller to release or reel in the rope. When only one take-up roller is used, rotating the limiting worm gear, in conjunction with the limiting worm wheel, drives the corresponding threaded tube to rotate. This, in turn, allows the rotating threaded tube to move and adjust the corresponding locking block, pressing it tightly against the corresponding take-up roller, thus fixing the position of the unused take-up roller. Rotating the adjusting lifting rod then moves the linkage gear away from the unused take-up roller via the moving frame, separating the linkage gear from the linkage gear ring on the outer surface of the unused take-up roller. When the rotating motor drives the rotating rod, the rotating rod, in conjunction with the linkage gear, drives only the still-engaged linkage gear ring to rotate. This allows the equipment to be structurally adjusted according to actual usage, meeting different suspension requirements and enabling the equipment to efficiently perform its intended functions.

[0020] (2) In this invention, during use, by rotating the first adjusting worm, the rotating first adjusting worm, in conjunction with the first adjusting worm wheel, can drive the corresponding first adjusting gear to rotate. Then, under the position restriction of the first adjusting rack, the first adjusting gear, in conjunction with the side block, can drive the corresponding extension strip to one side of the corresponding hole. Then, by rotating the second adjusting worm, the rotating second adjusting worm, in conjunction with the second adjusting worm wheel, can drive the second adjusting gear to rotate. Then, under the position restriction of the second adjusting rack, the second adjusting gear, in conjunction with the sliding frame, can move the guide ring to the corresponding hole. Then, the rope passes through the guide ring, so that the rope is less likely to deviate at a large angle during use, thereby preventing the rope from contacting the inner wall of the hole, thus ensuring the integrity of the hole, and improving the stability of the actual suspension, so that the equipment can efficiently realize its intended function.

[0033] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0034] For examples, please refer to [link / reference]. Figures 1-3 A subway track top ventilation duct installation device, consisting of a support mechanism 1 and an adjustment mechanism 2.

[0035] The details are as follows:

[0036] Please see Figures 4-8The support mechanism 1 includes two base frames 101, two side frames 102, a top frame 104, a rotating component, and a limiting component. The two side frames 102 are fixedly connected between the opposite outer surfaces of the two base frames 101, and the top frame 104 is fixedly connected between the tops of the two base frames 101. Four movable threaded rods 105 are rotatably connected between the opposite inner surfaces of the two sides of the top frame 104.

One side of the outer surface of each extension block 108 is engaged with the corresponding side of the outer surface of the movable block 107. One side of the outer surface of each extension block 108 is fixedly connected with a guide block 109 by bolts. Each guide block 109 has a guide block 109 fixedly connected to its corresponding side of the outer surface of the movable block 107. One side of the extension block 108 is snapped together. A mounting frame 114 is fixedly connected to one side of the top frame 104. Two take-up rollers 115 are rotatably connected to the top and bottom surfaces of the mounting frame 114. Each take-up roller 115 has a connecting gear ring 116 fitted onto its outer surface. Rotating and limiting components are mounted on the mounting frame 114. Each side frame 102 has a moving groove at its top. The top of each bottom block 201 slides through the corresponding moving groove. A first adjusting rack 103 is fixedly connected to the top surface of one side frame 102. A guide wheel 110 and a guide rod 111 are rotatably connected to one side of the outer surface of each guide block 109. Four moving motors 106 are fixedly connected to the other side of the top frame 104. The output end of each moving motor 106 and... One end of each movable threaded rod 105 is fixedly connected. Two sets of rotating components are provided. Each set includes a rotating rod 118, a connecting gear 119, a moving frame 121, a lifting rod 120, and a rotary motor 117. The rotating rod 118 is rotatably connected between the inner top and inner bottom surfaces of the mounting frame 114, and its top end extends to the outside of the mounting frame 114. A slot is provided on the outer surface of the rotating rod 118. The lifting rod 120 is rotatably connected between the inner top and inner bottom surfaces of the mounting frame 114. The moving frame 121 is threaded to the outer surface of the lifting rod 120 and slidably sleeved on the outer surface of the rotating rod 118. The connecting gear 119 is rotatably connected between the opposite outer surfaces of the moving frame 121 on both sides. The inner wall of the mounting bracket 114 is engaged with the rotating rod 118 via a slot. The connecting gear 119 meshes with the two corresponding connecting gear rings 116. The rotary motor 117 is fixedly connected to the top of the mounting bracket 114, and its output end is fixedly connected to the top of the rotating rod 118. Four sets of limiting components are provided. Each set includes a threaded tube 122, a limiting worm gear, a limiting worm 125, a push rod 123, and a locking block 124. The threaded tube 122 is rotatably connected to the inner wall of the mounting bracket 114. The limiting worm gear is sleeved on the outer surface of the threaded tube 122. The limiting worm 125 is rotatably connected to the inner wall of the mounting bracket 114, and the limiting worm 125 meshes with the limiting worm gear. The push rod 123 is threadedly connected to the inside of the threaded tube 122, and the locking block 124 is fixedly connected to one end of the push rod 123.Two sets of first limiting strips 113 and two sets of second limiting strips 112 are fixedly connected between the inner surfaces of the two sides of the top frame 104. Each set of first limiting strips 113 has two strips. The outer surface of one side of each first limiting strip 113 is in contact with the outer surface of the corresponding moving block 107. The outer surfaces of both sides of each second limiting strip 112 are in contact with the two corresponding moving blocks 107. The support mechanism 1 is moved to the designated use hole through the base frame 101. The existing suspension rope is wound in an orderly manner around the outer surface of the take-up roller 115. At the same time, one end of the rope is passed through the corresponding guide wheel 110 and guide block 109. The gap between them is adjusted, and according to actual usage requirements, the corresponding position moving motor 106 is activated by control, so that the moving motor 106 can drive the corresponding moving threaded rod 105 to rotate. This allows the rotating moving threaded rod 105 to move the adjusting block 107 to one side of the corresponding hole, so that one end of the rope passes through the guide rod 111 and is pulled to the corresponding hole. At this point, by adding or removing extension blocks 108 according to the actual position of the hole, the rope can be suspended in a largely vertical state. Then, by controlling the activation of the rotating motor 117, the rotating motor 117 can drive... The rotating rod 118 rotates, which in turn drives the corresponding connecting gear 119 to rotate. The connecting gear 119 then drives the two corresponding connecting gear rings 116 to rotate, which in turn drives the corresponding take-up roller 115 to rotate. This allows the take-up roller 115 to release or take up the rope. Simultaneously, when only one take-up roller 115 is used, rotating the limiting worm gear 125, in conjunction with the limiting worm wheel, drives the corresponding threaded tube 122 to rotate. This, in turn, allows the rotating threaded tube 122 to engage with the push rod 123. The movable adjustment corresponding locking block 124 presses tightly against the corresponding take-up roller 115, thereby fixing the position of the unused take-up roller 115. Then, by rotating the adjusting lifting rod 120, the rotating lifting rod 120 drives the connecting gear 119 away from the unused take-up roller 115 via the movable frame 121. This causes the connecting gear 119 to disengage from the connecting gear ring 116 on the outer surface of the unused take-up roller 115. Subsequently, when the rotary motor 117 drives the rotating rod 118 to rotate, the rotating rod 118, in conjunction with the connecting gear 119, can only drive the still-engaged connecting gear ring 116 to rotate.

[0037] Please see Figures 9-11The adjustment mechanism 2 is provided in multiple sets. Each set of adjustment mechanism 2 includes two base blocks 201, an extension bar 202, four sliding frames 204, and a moving component. The two base blocks 201 are slidably inserted into the corresponding side frame 102. The extension bar 202 is fixedly connected between the tops of the two base blocks 201. The four sliding frames 204 are slidably sleeved on the outer surface of the extension bar 202. A guide ring 211 is fixedly connected to one side of the outer surface of each sliding frame 204. The moving component is set on the extension bar 202. Each set of moving components includes a side rod 207, a side block 208, a first adjusting gear 209, and a first adjusting worm gear 21. 0 and the first adjusting worm gear, the side rod 207 is rotatably connected to one end of the corresponding extension bar 202, the side block 208 is threaded to the outer surface of the side rod 207, the first adjusting gear 209 is rotatably connected to one side of the outer surface of the side block 208, each first adjusting gear 209 meshes with the first adjusting rack 103, the first adjusting worm gear is fixedly connected to one end of the first adjusting gear 209, the first adjusting worm 210 is rotatably connected to one side of the outer surface of the side block 208, the first adjusting worm 210 meshes with the first adjusting worm gear, each slide frame 204 has a second adjusting gear 205 rotatably connected between the two sides of the opposite inner surface wall, each Each of the second adjusting gears 205 has a second adjusting worm gear fixedly connected to one end. Each slide frame 204 has a second adjusting worm 206 rotatably connected to one outer surface. Each second adjusting worm 206 meshes with its corresponding adjusting worm gear. Each extension bar 202 has a second adjusting rack 203 fixedly connected to its bottom. Each second adjusting rack 203 meshes with its corresponding second adjusting gear 205. Each slide frame 204 has a locating bolt threaded to its top. By rotating the first adjusting worm 210, the rotating first adjusting worm 210, in conjunction with the first adjusting worm gear, can drive the corresponding first adjusting gear 209 to rotate. Under the positional constraint of the first adjusting rack 103, the first adjusting gear 209, in conjunction with the side block 208, can drive the corresponding extension bar 202 to move to the side of the corresponding hole. Then, by rotating through the second adjusting worm 206, the rotating second adjusting worm 206, in conjunction with the second adjusting worm wheel, drives the second adjusting gear 205 to rotate. Consequently, under the positional constraint of the second adjusting rack 203, the second adjusting gear 205, in conjunction with the sliding frame 204, can move the guide ring 211 to the corresponding hole, and then the rope passes through the guide ring 211, so that the rope is less likely to deviate at a large angle during use.

[0038] The following provides a detailed description of the method of using a subway track top ventilation duct installation device provided by an embodiment of the present invention. The method of use includes the following steps:

[0039] Step 1, Suspension Processing: Move the support mechanism 1 to the designated hole via the base frame 101. Orderly wind the existing suspension rope around the outer surface of the take-up roller 115, simultaneously threading one end of the rope through the gap between the corresponding guide wheel 110 and the guide block 109. Then, according to actual usage requirements, activate the corresponding position moving motor 106 to drive the corresponding moving threaded rod 105 to rotate. This rotating moving threaded rod 105 then moves the adjusting block 107 to one side of the corresponding hole, thereby allowing the rope to... After passing through the guide rod 111, one end is pulled to the corresponding hole. At this point, by adjusting the extension blocks 108 according to the actual position of the hole, the rope can be suspended in a largely vertical state. Then, the rotary motor 117 is activated, causing it to rotate the corresponding rotary rod 118. The rotating rod 118 then drives the corresponding connecting gear 119, which in turn drives the two connecting gear rings 116. It can drive the corresponding take-up roller 115 to rotate, allowing the take-up roller 115 to release or reel in the rope. When only one take-up roller 115 is used, rotating the limiting worm gear 125, in conjunction with the limiting worm wheel, drives the corresponding threaded tube 122 to rotate. This rotating threaded tube 122, in conjunction with the push rod 123, moves and adjusts the corresponding locking block 124 to press tightly against the corresponding take-up roller 115, thus fixing the position of the unused take-up roller 115. Then, rotating the adjusting lifting rod 120... The movable frame 121 can drive the connecting gear 119 away from the unused take-up roller 115, thereby separating the connecting gear 119 from the connecting gear ring 116 on the outer surface of the unused take-up roller 115. Then, when the rotary motor 117 drives the rotating rod 118 to rotate, the rotating rod 118, in conjunction with the connecting gear 119, can drive only the still meshed connecting gear ring 116 to rotate. This allows the equipment to adjust its structure according to actual usage, thereby meeting different suspension requirements and enabling the equipment to efficiently perform its intended functions.

[0040] Step 2, Protective Measures: By rotating the first adjusting worm 210, the rotating first adjusting worm 210, in conjunction with the first adjusting worm wheel, drives the corresponding first adjusting gear 209 to rotate. Then, under the positional constraint of the first adjusting rack 103, the first adjusting gear 209, in conjunction with the side block 208, drives the corresponding extension bar 202 to move to one side of the corresponding hole. Next, by rotating the second adjusting worm 206, the rotating second adjusting worm 206, in conjunction with the second adjusting worm wheel, drives the second adjusting gear 205 to rotate. Then, under the positional constraint of the second adjusting rack 203, the second adjusting gear 205, in conjunction with the sliding frame 204, moves the guide ring 211 to the corresponding hole. The rope is then passed through the guide ring 211, preventing the rope from deviating at a large angle during use, thus preventing the rope from contacting the inner wall of the hole, ensuring the integrity of the hole, and improving the stability of the actual suspension, enabling the equipment to efficiently perform its intended functions.

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