Description

Technical Field

[0001] The invention relates to the technical field of lifting auxiliary guidance, and in particular to a lifting auxiliary guidance device for a dust removal box of a material shed cruising dust control system. Background Art

[0002] In the industrial production process, material sheds are the key link in material storage and transportation, and often need to store a variety of raw materials such as coal, stone, iron ore, lime, coke, etc. However, the storage and transportation of these materials are often accompanied by the generation of a large amount of dust, which not only threatens the health of workers, but also may cause serious pollution to the surrounding environment.

[0003] In order to effectively solve this problem, the material shed cruising dust control system came into being. The system is similar in appearance to the overhead crane in the workshop (such as the Chinese utility model patent with publication number CN212050206U, named a dust removal lifting device). The dust box is slidably set on the track of the bridge bracket to achieve automatic cruising dust removal of the dust box. Among them, the air pipe, liquid pipe and cable used to connect to the dust box are usually passed through the drag chain and move with the dust box, and the drag chain is generally guided by the bracket set parallel to the dust box track.

[0004] The dust box needs timely maintenance during operation. When maintenance is needed, the current measures are generally to carefully lower the unloaded dust box to the ground by an external crane, or to lower it to the ground by a built-in lifting mechanism, and then raise it to the installation location after maintenance by the staff. However, no matter which of the above methods is used, the dust box faces some technical challenges during the lifting process: When the dust removal box descends, as the number of vertical drag chains gradually increases, the drag chains are prone to slide due to their own gravity or inertia; when the dust removal box rises, the vertical drag chains are prone to bend under the action of their own gravity, resulting in failure to smoothly enter the bracket.

[0005] Therefore, in view of the problems existing in the drag chain during the lifting process of the dust removal box in the material shed cruising dust control system, it is particularly urgent to invent a dust removal box lifting auxiliary guide device for the system. Summary of the invention

[0006] The purpose of the present invention is to provide a dust box lifting auxiliary guide device for a material shed cruising dust control system, so as to solve the problem that in the existing material shed cruising dust control system, when the dust box is lowered during use, as the vertical drag chains gradually increase, the drag chains are prone to slide due to their own gravity or inertia; when the dust box is raised, the vertical drag chains are prone to bend under the action of their own gravity, resulting in the problem that they cannot enter the bracket smoothly.

Since it is an existing equipment, it is not repeated here.

[0028] Specifically, rubber sleeves are fixed to the outer sides of the first roller 34 and the second roller 37. The provision of the rubber sleeves can increase the friction between the first roller 34 and the second roller 37 and the drag chain 8, and the rubber sleeves can prevent the first roller 34 and the second roller 37 from crushing the drag chain 8.

[0029] Specifically, the guide frame 3 also includes an adjustment frame 33, wherein the adjustment frame 33 includes a third cylinder 331, a mounting frame 332, a sliding rod 333, a sleeve 334, a rotating electric cylinder 335, a turntable 336, an auxiliary rod 337 and a third roller 338; the third cylinder 331 is fixed to the outer side of the frame body 31 by bolts, wherein the output end of the third cylinder 331 is fixed with the mounting frame 332 by bolts; at least one sliding rod 333 is fixed to the lower side of both ends of the mounting frame 332 by welding, wherein the sliding rod 333 slides through a sleeve 334, and the sleeve 334 is fixed to the outer side of the frame body 31 by bolts; the interior of the mounting frame 332 is fixed with a rotating electric cylinder 335 by bolts, wherein the rotating electric cylinder 335 A turntable 336 is fixed to the output end of the cylinder 335; the turntable 336 is rotatably mounted on the upper end of the mounting frame 332 through a supporting bearing, wherein an auxiliary rod 337 is fixed to the outer side of the turntable 336 by welding, and a third roller 338 is rotatably mounted on the outer side of the auxiliary rod 337 through a supporting bearing. After the first roller 36 and the second roller 37 clamp the drag chain 8, the turntable 336 can be driven to rotate by the rotating electric cylinder 335, thereby moving the third roller 338 to the lower side of the connection position between the horizontally arranged drag chain 8 and the vertically arranged drag chain 8, and then the mounting frame 332 is driven to move upward by the third cylinder 331, thereby supporting the connection position between the horizontally arranged drag chain 8 and the vertically arranged drag chain 8.

[0030] Specifically, the guide frame 3 also includes a speed sensor 314 and an alarm 315. The speed sensor 314 is fixed to the inside of the frame 31 by bolts, wherein the detection end of the speed sensor 314 is arranged on the outside of the first winding shaft 36, and the speed sensor 314 adopts a turbine speed sensor; the speed sensor 314 is electrically connected to the alarm 315, wherein the alarm 315 is fixed to the outer side of the frame 31 by bolts. When in use, the speed sensor 314 can detect the rotation speed of the first winding shaft 36. If the weight and inertia of the drag chain 8 make it impossible to manually control the retracting and releasing mechanism 2, the drag chain 8 will drive the first roller 34, the rotating column 35 and the first winding shaft 36 to overspeed in turn. At this time, the speed sensor 314 can transmit a signal to the electrical control cabinet of the feeding shed cruising dust control system, and the electrical control cabinet starts the alarm 315, which can sound an alarm through the alarm 315.

[0031] Specifically, the guide frame 3 also includes a first brake wheel 310, a first brake frame 311, an electric push rod 312 and an auxiliary frame 313. The first brake wheel 310 is fixed on the outer side of the first winding shaft 36, wherein the first brake frame 311 is arranged on one side of the first brake wheel 310; the side of the first brake frame 311 away from the first brake wheel 310 is fixed to the inner wall of the frame body 31 through the electric push rod 312, wherein the upper and lower side surfaces of the first brake frame 311 are slidably mounted with the auxiliary frame 313, and the auxiliary frame 313 is fixed to the frame body 31 by bolts; the electric push rod 312 is connected to the speed sensor 314 through a data cable, and when the speed sensor 314 detects that the first winding shaft 36 is rotating at an overspeed, the electric push rod 312 will drive the first brake frame 311 to squeeze the first brake wheel 310, and then brake the first roller 34, thereby fixing the drag chain 8.

[0032] Specifically, the retracting mechanism 2 includes a shell 21, a second reel 22, a hand wheel 23, a second brake wheel 24, a second brake frame 25 and a stud 26.

When in use, the user can drive the second winding shaft 22 to rotate through the hand wheel 23, thereby winding or unwinding the first steel cable 1 and the second steel cable 10 accordingly. When there is no need to wind up or unwind the first steel cable 1 and the second steel cable 10, the stud 26 can be manually rotated, thereby causing the second brake frame 25 to rotate the second brake wheel 24, thereby braking the second winding shaft 22.

[0033] Specifically, a translation frame 14 is slidably arranged on the bracket 7, wherein a fourth roller 13 is rotatably mounted on the translation frame 14; the outer side surface of the translation frame 14 is slidably connected to the fixed frame 17, wherein both ends of the fixed frame 17 are fixed to the bracket 5; a traction rope 15 is fixed to the end of the translation frame 14 away from the drag chain 8, wherein the other end of the traction rope 15 is connected to the winding mechanism 16, and the winding mechanism 16 is fixed on the bracket 1; the drag chain 8 passes through the fourth roller 13 and the drag chain 8 is tensioned under the action of the winding mechanism 16. When the connection position of the two horizontally arranged drag chains 8 changes, the drag chain 8 can drive the translation frame 14 to slide on the bracket 7, and then through the cooperation of the translation frame 14, the fourth roller 13 and the fixed frame 17, the drag chain 8 can be prevented from detaching from the bracket 7. Secondly, through the cooperation of the traction rope 15 and the winding mechanism 16, a traction force can be applied to the translation frame 14, so that the traction force can improve the smoothness of the movement of the drag chain 8 in the bracket 7.

When in use, the third winding shaft 163 can tighten the traction rope 15 under the action of the winding spring 164, thereby providing traction force for the translation frame 14 through the traction rope 15.

[0035] The method of using this embodiment includes the following steps: 1) When the dust removal box 9 falls down through the cooperation of the retracting and unwinding mechanism 2 and the second steel cable 10, the retracting and unwinding mechanism 2 can synchronously unwind the first steel wire 1, and at the same time, the guide frame 3 is driven downward by the first cylinder 4. At this time, the loosened first steel wire 1 just cooperates with the guide frame 3 to move downward. After the guide frame 3 and the dust removal box 9 move downward for a certain distance, the guide frame 3 stops moving downward, and the first roller 34 and the second roller 37 clamp the drag chain 8 through the second cylinder 39. At the same time, the adjustment frame 33 supports the connection position of the horizontally arranged drag chain 8 and the vertically arranged drag chain 8. Then, as the dust removal box 9 continues to move downward, the drag chain 8 drives the first winding shaft 36 to rotate accordingly, thereby winding up the loosened first steel cable 1 of the retracting and unwinding mechanism 2. At this time, due to the clamping force of the first roller 34 and the second roller 36 on the drag chain 8 and the restriction of the first steel cable 1 on the rotating column 35, the drag chain 8 can be prevented from sliding quickly on the bracket 7 due to its own gravity; 2) When the dust removal box 9 rises through the cooperation of the retracting and releasing mechanism 2 and the second steel cable 10, the retracting and releasing mechanism 2 can synchronously reel up the first steel wire 1. At this time, the first steel wire 1 drives the first roller 34 to rotate accordingly through the first reeling shaft 36, and then drives the drag chain 8 to move upward through the rotation of the first roller 34, so as to avoid the vertical drag chain 8 from bending and being unable to move into the bracket 7 when the dust removal box 9 rises. When the dust removal box 9 rises to a certain height, the first roller 34 and the second roller 37 can release the clamping of the drag chain 8 through the second cylinder 39, and at the same time, the first cylinder 4 is started, and the guide frame 3 and the dust removal box 9 are driven to move upward synchronously through the first cylinder 4; 3) When the dust removal box 9 moves along the guide rail 6 through the electric walking mechanism or rises and falls with the lifting rail 12, the translation frame 14 can slide on the bracket 7 driven by the drag chain 8, and then through the cooperation of the translation frame 14, the fourth roller 13 and the fixed frame 17, the drag chain 8 can be prevented from detaching from the bracket 7. Secondly, through the cooperation of the traction rope 15 and the winding mechanism 16, traction force can be applied to the translation frame 14, so that the traction force can improve the smoothness of the movement of the drag chain 8 inside the bracket 7.

[0036] All kinds of components used in this application document are standard parts, and the specific connection methods of each part adopt mature conventional means such as sewing and gluing in the prior art. Each structure adopts conventional materials in the prior art, and no specific description is given here.

[0037] To sum up: the dust box lifting auxiliary guide device for the material shed cruising dust control system solves the problem that in the existing material shed cruising dust control system, when the dust box 9 is lowered during use, as the vertical drag chains 8 gradually increase, the drag chains 8 are prone to slide due to their own gravity or inertia; and when the dust box 9 rises, the vertical drag chains 8 are prone to bend under the action of their own gravity, resulting in the problem that they cannot smoothly enter the bracket 7.
