Description

Technical Field

[0001] The invention relates to the technical field of elevator accessories, and in particular to a device for preventing falling objects from a steel wire rope hole in an elevator machine room. Background Art

[0002] According to the Regulations on Safety Supervision of Special Equipment and the Catalogue of Special Equipment, elevators are clearly listed as special equipment by the state and are strictly supervised by the Special Equipment Market Supervision and Administration Bureau. Currently, elevators on the market, especially those with machine rooms, have corresponding openings (wire rope holes) on the floor of the elevator machine room where the wire rope passes due to the need for elevator installation. The national standard requires that this opening should be as small as possible on the basis of meeting the conditions of use. In order to prevent objects from falling into the shaft through this opening (if the protection is not in place, there is a risk that the machine room debris and maintenance personnel's tools will fall into the shaft, posing a serious threat to the safety of normal elevator components and maintenance personnel), a protective cover or anti-falling device is generally installed around it, and the protective cover must be at least 50 mm higher than the finished surface of the machine room floor. At present, when installing elevators, the usual method is to pile them with cement and bricks at the end of the elevator installation. The disadvantages of this method are: (1) the size cannot be adjusted dynamically; (2) it cannot be copied and factory-produced; (3) it is time-consuming and inefficient.

[0003] In order to solve the problem that the above-mentioned anti-falling object device cannot adjust the size, the patent document (authorization announcement number is CN205240992U) discloses a special waterproof platform for the wire rope hole in the elevator room, but the device has only one function of adjusting the size, which can only be adjusted in one direction and the height of the device cannot be adjusted. Summary of the invention

[0004] In order to solve the technical problems existing in the background technology, the present invention proposes a device for preventing falling objects from a wire rope hole in an elevator machine room.

[0005] The present invention provides an anti-falling device for a steel wire rope hole in an elevator machine room, which is installed at an opening hole in the elevator floor of the machine room through which the steel wire rope passes, and comprises:

[0006] A base assembly, comprising four positioning columns respectively installed at the four corners of the opening hole, wherein the positioning columns are slidably connected to the floor of the machine room through a sliding structure so that the positioning columns can slide along the length direction, width direction and diagonal direction of the opening hole respectively;

[0007] The cover plate assembly comprises a plurality of cover plates, wherein the cover plates are clamped between two adjacent positioning columns, and the size of the opening hole is adjusted by sliding the positioning columns to drive the cover plates to move.

[0008] Preferably, the positioning column is configured as an L-shaped column, and the angle of the L-shaped column during installation is consistent with the corner direction of the opening hole, and the two side panels of the L-shaped column extend along the length and width directions of the opening hole respectively; the cover plate is configured as an L-shaped plug-in plate, and the L-shaped plug-in plate includes a side panel and a top panel, and grooves are provided on the outer sides of the two side panels of the L-shaped column, and the side panel or the top panel of the L-shaped plug-in plate can be inserted into the groove, and the size of the top panel of the L-shaped plug-in plate is larger than the size of the side panel.

[0009] Preferably, the opening hole is provided with: two slide rails I respectively arranged on the length side and extending along the length direction, two slide rails II respectively arranged on the width side and extending along the width direction, and four slide rails III extending along the diagonal direction. At the four corners of the opening hole, the slide rails I, the slide rails II and the slide rails III are interconnected, and a lockable universal wheel is installed at the bottom of each L-shaped column, and the lockable universal wheel can slide in the slide rails I, the slide rails II and the slide rails III.

[0021] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar symbols throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0022] like Figure 1-3 As shown, the present embodiment provides an elevator machine room wire rope hole anti-falling device, which is installed at an opening hole 2 through which a wire rope 1 passes in the elevator floor of the machine room, and includes:

[0023] The base assembly includes four positioning columns respectively installed at the four corners of the opening hole 2, and the positioning columns are slidably connected to the floor of the machine room through a sliding structure so that the positioning columns can slide along the length direction, width direction and diagonal direction of the opening hole 2 respectively;

[0024] The cover plate assembly includes a plurality of cover plates, and each of the adjacent positioning columns is clamped with a cover plate. The positioning columns are slid to drive the cover plates to move so as to adjust the size of the opening hole 2.

[0025] In this way, by sliding the positioning column and driving the cover plate to move, the size of the opening hole 2 can be adjusted in a single length direction, a single width direction, or a bidirectional adjustment of the length and width, and the size of the opening hole 2 of the wire rope 1 can be dynamically adjusted. The positioning column and the cover plate are replicable and can be factory-produced, reducing material costs and labor costs; at the same time, the existing concrete anti-falling object step support formwork and pouring and solidification time are eliminated, shortening the construction period, reducing time costs, and improving engineering construction efficiency.

[0026] Furthermore, if Figure 1 and Figure 2As shown, the positioning column is set as an L-shaped column 3. The angle of the L-shaped column 3 during installation is consistent with the corner direction of the opening hole 2. The two side panels of the L-shaped column 3 extend along the length and width directions of the opening hole 2 respectively; the cover plate is set as an L-shaped plug plate 5, and the L-shaped plug plate 5 includes a side plate and a top plate. Grooves 4 are provided on the outer sides of the two side plates of the L-shaped column 3. The side plate or the top plate of the L-shaped plug plate 5 can be inserted into the groove 4, and the size of the top plate of the L-shaped plug plate 5 is larger than the size of the side plate.

[0027] Furthermore, the groove 4 extends in the up-down direction, and the height of the falling object prevention device is adjusted by the depth of the L-shaped plug plate 5 inserted into the groove 4 .

[0028] It should be noted that by inserting the side plate of the L-shaped plug plate 5 into the groove 4 or inserting the top plate into the groove 4, the size of the wire rope opening hole 2 and the height of the anti-falling object can be adjusted again.

[0029] Among them, the height of the L-shaped column 3 is at least 50 mm to meet the requirements of Clause 5.2.6.3.3 of GB / T7588.1-2020 "Safety Specifications for Elevator Manufacturing and Installation".

[0030] In this embodiment, Figure 3 As shown, the opening hole 2 is provided with: two slide rails I6 respectively arranged at the length side and extending in the length direction, two slide rails II7 respectively arranged at the width side and extending in the width direction, and four slide rails III8 extending in the diagonal direction. At the four corners of the opening hole 2, the slide rails I6, II7 and III8 are interconnected, and a lockable universal wheel is installed at the bottom of each L-shaped column 3, and the lockable universal wheel can slide in the slide rails I6, II7 and III8. Specifically, in order to facilitate movement, the lockable universal wheel is installed at the bottom end of the intersection of the two sides of the L-shaped column 3.

[0031] Among them, the specific structure of the lockable universal wheel can refer to the existing structure, and will not be repeated in this article.

[0032] When only the size of the opening hole 2 in the length direction needs to be adjusted, the lockable universal wheel at the bottom of the L-shaped column 3 slides from the connection of the slide rails Ⅰ6, Ⅱ7 and Ⅲ8 into the slide rail Ⅰ6, and then slides along the slide rail Ⅰ6 to adjust the size in the length direction; when only the size of the opening hole 2 in the width direction needs to be adjusted, the lockable universal wheel at the bottom of the L-shaped column 3 slides from the connection of the slide rails Ⅰ6, Ⅱ7 and Ⅲ8 into the slide rail Ⅱ7, and then slides along the slide rail Ⅱ7 to adjust the size in the width direction; when both the length and width directions of the opening hole 2 need to be adjusted, the lockable universal wheel at the bottom of the L-shaped column 3 slides from the connection of the slide rails Ⅰ6, Ⅱ7 and Ⅲ8 into the slide rail Ⅲ8, and then slides along the slide rail Ⅲ8 to adjust the size in the length and width directions at the same time. In this way, the size of the opening hole 2 can be quickly and conveniently adjusted dynamically.

[0033] In order not to affect the movement of personnel and save space, slide rails I6, II7 and III8 are configured as embedded slide rails, and the upper end surfaces of slide rails I6, II7 and III8 are flush with the floor of the machine room.

[0034] In summary, the size of the opening hole 2 for the wire rope in the machine room is minimized by adjusting the two dimensions of the base assembly and the top cover assembly. At the same time, the height of the anti-falling object device is adjusted by inserting the L-shaped plug plate 5 into the groove 4 of the L-shaped column 3. At the same time, the height of the anti-falling object device is adjusted for the second time by inserting the top plate or side plate of the L-shaped plug plate 5 into the groove 4, so that it is at least not lower than the finished ground by 50mm, so as to meet the requirements of Clause 5.2.6.3.3 of GB / T7588.1-2020 "Safety Code for Elevator Manufacturing and Installation".

[0035] It should be noted that the height of the L-shaped column 3 itself can be customized according to actual needs during production to adjust the height of the anti-falling device. Among them, the sizes of the top plate and side plates of the L-shaped plug plate 5 can also be customized according to actual needs during production.
