Technical Field
[0001] This utility model relates to the field of construction elevator technology, and more specifically, to a construction elevator cable rack with a cleaning function. Background Technology
[0002] Construction elevators, as an indispensable piece of equipment in modern construction, undertake critical tasks such as vertical transportation of personnel and materials, greatly improving construction efficiency. During operation, the cables of construction elevators are often exposed to the external environment, directly facing complex construction site conditions. The area around the building is accompanied by a large amount of dust and debris. This dust not only affects the overall aesthetics of the construction elevator, but more importantly, it gradually accumulates on the cable surface, forming a layer of dirt that is difficult to remove. This layer of dirt not only further deteriorates the appearance of the cable, but more importantly, it weakens the cable's insulation performance. Over time, the continuous accumulation of dust and dirt will lead to accelerated aging of the cable insulation layer, and may even cause electrical faults, posing a serious threat to the safe operation of the construction elevator. Utility Model Content

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0020] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0021] like Figure 1As shown, this utility model provides a construction elevator cable rack with a cleaning function, including a mounting frame 10 for fixing cables. The mounting frame 10 includes a first angle steel 11 and a steel hoop 12 disposed on one side thereon. In the prior art, to prevent cables from swinging arbitrarily with the rise and fall of the construction elevator, causing wear and leakage, a steel hoop 12 is set to limit their swing. Since the cable winding and unwinding must pass through the steel hoop 12 during the operation of the construction elevator, this application sets a cleaning device at this location, which cleans itself based on the operation of the construction elevator. Specifically, a cable tray 20 is set at the center of the mounting frame 10. The cable tray 20 is for... The system consists of two hinged semicircular frames 21. The top and bottom of the semicircular frames 21 are respectively provided with fan-shaped plates 22. An arc-shaped plate 23 is provided on the fan-shaped plate 22 located above the semicircular frames 21. Several cleaning brushes 30 are provided inside the semicircular frames 21. Several brush holder mounting parts 25 are provided inside the semicircular frames 21. Cleaning brushes 30 are provided on the brush holder mounting parts 25. The bristles of the several cleaning brushes 30 form a circle on one side. When the cable of the construction elevator is located inside the cable tray 20, the bristles of the cleaning brushes 30 completely cover it in the horizontal direction. One of the semicircular frames 21 is fixed together with the first angle steel 11.
[0022] like Figure 2-3 The semicircular frame 21 shown includes semicircular frame 21a and semicircular frame 21b. Several second angle steels 13 are welded between the middle of semicircular frame 21a and the first angle steel 11. A tie rod 14 is provided between the arc-shaped plate 23 on semicircular frame 21a and the first angle steel 11. Mutual mating parts 24 are provided at the top and bottom ends of semicircular frame 21a and semicircular frame 21b. The mating parts 24 are fixed by pins; that is, when fixing the cable, opening the pin between semicircular frame 21b and semicircular frame 21a allows it to unfold to the desired position. Figure 2 As shown, placing the cable in the inner arc of the semicircular frame 21a will close the semicircular frame 21b. At this time, the cleaning brush 30 on the cable tray 20 can perform self-cleaning operation as the cable moves up and down.
[0023] In a preferred embodiment, a cable limiting clamp 26 is provided on the inner side of the arc plate 23. The inner diameter of the circle formed by the cable limiting clamps 26 on the two arc plates 23 is smaller than the inner diameter of the circle formed by the two sector plates 22. A cable limiting clamp 26 of the same size is provided below the sector plate 22 on the bottom side of the semi-circular frame 21. The cable limiting clamp 26 can limit the amplitude of cable swaying inside the cable tray 20, and reduce the cleaning force of each cleaning brush 30 on any surface to a suitable range.
[0024] like Figure 4As shown, the cleaning brush 30 includes a mounting rod 31 and a brush plate 36. The mounting rod 31 is detachably mounted on the brush holder mounting part 25. A sliding groove 3101 is provided on the side of the mounting rod 31 near the bottom. A slider 35 is slidably mounted on the sliding groove 3101. The brush plate 36 is arranged parallel to the side of the mounting rod 31 near the slider 35. A spring telescopic rod 34 is provided between the slider 35 and the brush plate 36. A first rocker arm 32 and a second rocker arm 33 are also provided between the mounting rod 31 and the brush plate 36.
[0025] Furthermore, the two ends of the first rocker arm 32 are respectively hinged to the mounting rod 31 and the brush plate 36 near the top. One end of the second rocker arm 33 is located between the sliding groove 3101 and the hinge of the first rocker arm 32, and the other end is hinged to the brush plate 36 near the bottom. The hinge of the spring telescopic rod 34 and the slide plate is located on the brush plate 36 near the middle.
[0026] The above describes the movable connection between the mounting rod 31 and the sliding plate on the cleaning brush 30. Specifically, during the up-and-down movement of the cable, the friction between the cable and the bristles on the brush plate 36 causes the brush plate 36 to tend to follow the cable's movement. After a certain displacement, the elastic force of the spring telescopic rod 34 causes it to generate a restoring force. Thus, the brush plate forms a structure that automatically reciprocates. During this up-and-down reciprocating movement, the inner radius formed by the several brush plates 36 changes, meaning the clamping force of the bristles on the cable also changes. Under these conditions, the cable surface can be cleaned more effectively.
[0027] In this embodiment, the side of the brush plate 36 away from the mounting rod 31 is an arc-shaped surface. The diameter of the circle formed by the brush plates 36 is larger than the diameter of the construction elevator cable, and the diameter of the circle formed by the bristles on the brush plates 36 is smaller than the diameter of the construction elevator cable.
[0028] It should be noted that the cable's interior is metal, and it is quite heavy. Clamping it with bristles will not interfere with the cable's recycling and elongation.
[0029] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
