[0003] During the dismantling of a vertical elevator, various elevator components such as hall doors, upper and lower sills, door operators, guardrails, car tops, and car walls need to be removed in sequence until the shaft is finally cleaned. During the entire dismantling process, a large amount of dust will be attached to the various components of the elevator, and cutting devices are often used for cutting operations, which will generate a lot of flying dust and cause air pollution.

[0004] Based on the above background, the inventors designed a dust collection cover structure and dust collection system for disassembling vertical elevators to solve the above problems, and thus, this application is hereby filed. Utility Model Content

[0005] The purpose of this application is to provide a dust collection cover structure and dust collection system for dismantling vertical elevators, so as to solve the problem of excessive dust and air pollution caused by the dismantling of vertical elevators.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following solution:

[0007] On the one hand, this application provides a dust collection cover structure for disassembling a vertical elevator, including a dust collection cover body for drawing out dusty air in the elevator shaft, and a locking component for locking the dust collection cover body to the top of the elevator car via an elevator cable.

[0008] The locking component is movably connected to the bottom of the dust cover body;

[0009] The dust collection cover body includes a through structure for the elevator cable to pass freely, and the dust collection cover body is also provided with an air extraction pipe connector for connecting with the air extraction pipe.

[0012] The base plate is provided with several air extraction holes;

[0013] The two ends of the through structure are fixed to the cover plate and the bottom plate, respectively.

[0014] Optionally, the distribution density of the air extraction holes is uniform or decreases from the periphery to the center of the cover plate.

[0015] Optionally, it also includes a handheld suction hose connected to the negative pressure suction chamber, the end of which is provided with a horn-shaped suction head.

[0016] Optionally, the locking assembly includes at least two force-transmitting diagonal bars hinged to the bottom of the vacuum cleaner cover body, and a locking tube fixed to one end of the force-transmitting diagonal bars away from the vacuum cleaner cover body.

[0017] The number of locking segments is the same as the number of force-transmitting diagonal bars;

[0018] The locking assembly also includes clamps for pressing the locking segments onto the elevator cable, with the locking segments all located within the clamps.

[0019] Optionally, the inner surface of the locking tube is provided with an anti-slip pad or anti-slip texture to increase frictional resistance.

[0020] Optionally, there are four force transmission diagonal bars and four locking tubes, which are distributed in four directions on the main body of the dust collection cover.

[0021] Optionally, the inner surface of the locking tube is arc-shaped, and the central angle corresponding to the arc is in the range of 75° to 90°.

[0024] The thin-walled hose is wound onto the winch.

[0025] The beneficial effects of this utility model are:

[0026] This application, by setting up a dust collection cover body and a locking component, allows the dust collection cover body to be suspended directly above the elevator car top via the locking component. As the dismantling work progresses, the dust collection cover body can move along with the elevator car top, thereby continuously removing dust in the dismantling work area. This prevents a large amount of dusty air from escaping from the elevator shaft and various floors to the vicinity of the elevator shaft, thus effectively solving the problem of excessive dust and air pollution caused by the dismantling of vertical elevators.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0033] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0034] Example 1:

[0035] like Figure 1 As shown, this embodiment provides a dust collection cover structure for disassembling a vertical elevator, including a dust collection cover body 1 for drawing out dusty air from the elevator shaft, and a locking component 2 for locking the dust collection cover body 1 directly above the elevator car top 5 via an elevator cable 3.

[0036] Locking component 2 is movably connected to the bottom of the dust cover body 1;

[0037] The dust collection cover body 1 includes a through structure 13 for the elevator cable 3 to pass freely through, and the dust collection cover body 1 is also provided with an air extraction pipe connector for communicating with the air extraction pipe.

[0038] This embodiment, by setting up a dust-collecting cover body 1 and a locking component 2, allows the dust-collecting cover body 1 to be suspended directly above the elevator car top 5 via the locking component 2. As the dismantling work progresses, the dust-collecting cover body 1 can move along with the elevator car top 5, thereby continuously removing dust in the dismantling work area. This prevents a large amount of dusty air from escaping from the elevator shaft and various floors to the vicinity of the elevator shaft, thus effectively solving the problem of excessive dust and air pollution caused by the dismantling of vertical elevators.

[0039] Specifically, in this embodiment, as Figure 1 As shown, the dust collection cover body 1 includes an arched cover plate 11 and a flat bottom plate 12. The cover plate 11 is fastened and fixed to the bottom plate 12. The dust collection cover body 1 has a negative pressure dust collection chamber 101 located between the cover plate 11 and the bottom plate 12.

[0040] The air extraction pipe connector is located on the cover plate 11 and is connected to the negative pressure dust collection chamber 101;

[0041] The base plate 12 is provided with a plurality of air extraction holes 121;

[0042] The two ends of the through structure 13 are fixed to the cover plate 11 and the base plate 12, respectively. Air extraction holes 121 are provided on the base plate 12, allowing the dust extraction cover body 1 to form a negative pressure dust extraction area above the disassembly work area. This quickly removes dust and particulate matter generated during disassembly, preventing large amounts of dust and particulate matter from spreading into the atmosphere and polluting the air environment.

[0043] Specifically, in this embodiment, as Figure 1As shown, the distribution density of the air extraction holes 121 is uniform or decreases from the periphery to the center of the cover plate 11, thereby improving the dust extraction effect in the area near the side wall of the elevator shaft.

[0044] Specifically, in this embodiment, as Figure 1 As shown, it also includes a handheld suction hose 4 connected to the negative pressure suction chamber 101. The end of the handheld suction hose 4 is provided with a horn-shaped suction head 41. The handheld suction hose 4 is provided so that the disassembly personnel can align the horn-shaped suction head 41 of the handheld suction hose 4 with the cutting area according to the actual working conditions, such as when track cutting is required, thereby further improving the dust collection effect.

[0045] Specifically, in this embodiment, as Figure 1 As shown, the locking assembly 2 includes at least two force transmission diagonal rods 21 hinged to the bottom of the dust cover body 1, and a locking tube 22 fixed to one end of the force transmission diagonal rods 21 away from the dust cover body 1.

[0046] The number of locking segments 22 is the same as the number of force-transmitting diagonal bars 21;

[0047] The locking assembly 2 also includes a clamp 23 for pressing the locking tube 22 onto the elevator cable 3. The locking tube 22 is located inside the clamp 23. By setting the force transmission diagonal bar 21 and the locking tube 22, the weight of the dust collection cover body 1 is applied to the locking tube 22 through the force transmission diagonal bar 21. The locking effect is achieved by using the friction between the locking tube 22 and the elevator cable 3. The clamp 23 can further increase the frictional resistance, making the dust collection cover body 1 and the elevator cable 3 more stable and preventing the dust collection cover body 1 from sliding down.

[0048] Specifically, in this embodiment, as Figure 1 As shown, the inner surface of the locking tube 22 is provided with an anti-slip pad or anti-slip pattern to increase frictional resistance. The anti-slip pad or anti-slip pattern can increase the coefficient of friction, thereby increasing frictional resistance.

[0049] Specifically, in this embodiment, there are four force transmission diagonal rods 21 and four locking tubes 22, which are distributed in four directions on the dust collection cover body 1.

[0050] Specifically, in this embodiment, the inner surface of the locking tube 22 is arc-shaped, and the central angle corresponding to the arc is up to 90° to increase the contact area. The specific values ​​can be set by technicians according to their needs, and will not be elaborated here.

[0051] Example 2:

[0052] like Figure 2As shown, this embodiment provides a dust collection system for disassembling a vertical elevator, including any of the above-described dust collection cover structures for disassembling a vertical elevator, and also includes a suction assembly 6 for providing a suction power source. The suction assembly 6 includes a suction pump 61 disposed on the elevator maintenance platform, and a thin-walled hose 62 with one end connected to the suction end of the suction pump 61 and the other end connected to the suction pipe connector on the dust collection cover body 1.

[0053] In this embodiment, a winch 7 is also included for installation on the elevator maintenance platform;

[0054] The thin-walled hose 62 is wound on the winch 7. The winch 7 is provided to prevent the thin-walled hose 62 from being scattered and makes it easy to store and move.

[0055] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of this utility model, and the utility model is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of this utility model, and these modifications and improvements are also considered to be within the protection scope of this utility model.
