Description

Technical Field

[0001] This utility model relates to the field of elevator technology, and in particular to a suspended lifting structure for a car. Background Technology

[0002] like Figure 1 As shown, the car suspension structure of an elevator in the prior art typically includes a car frame 20 that is circumferentially enclosed in the car 10. At the same time, side damping pads 30 and bottom damping pads 40 are installed between the inner side of the car frame 20 and the outer wall of the car 10. The lifting structure of the car 10 is installed on the lower outer extension of the car frame 20, as shown by the arrow in the figure.

[0003] The existing car suspension structure is complex, heavy, and takes up a lot of space. In some cases, it is even impossible to install shock-absorbing pads between the car frame and the car, resulting in a poor user experience. Utility Model Content

[0004] To address the aforementioned issues, this application provides a structurally sound suspended lifting structure for car cabins, thereby effectively simplifying the suspended lifting structure of the car cabins, reducing space occupation, improving space utilization, and ensuring effective shock absorption through shock-absorbing components, thus guaranteeing a superior user experience.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A suspended lifting structure for a car includes a car, a crossbeam is installed on the outer top or bottom surface of the car, and a shock-absorbing component is installed between the crossbeam and the car; symmetrically arranged rollers are rotatably installed at both ends of the crossbeam, the axes of the two sets of rollers are parallel to each other, and a lifting cable is wound around the bottom of the rollers. The two ends of the lifting cable extend outward from the side of the corresponding roller and upward to form a lifting structure.

[0007] As a further improvement to the above technical solution:

[0008] The roller has an outwardly extending annular ridge on its circumferential surface, which, together with the roller end face, forms a concave space for accommodating the lifting cable.

[0009] The lifting cable includes two or more cables spaced apart along the axial direction of a single set of rollers.

[0010] The crossbeam is a bottom beam installed on the outer bottom surface of the car. The bottom beam includes a beam body with an upward-opening U-shaped cross-section. The two ends of the beam body extend outwards in opposite directions to form a connecting plate. The roller is housed in the opening of the beam body, and the axially extending support shafts at both ends of the roller are installed on the corresponding connecting plate.

[0011] It also includes a U-shaped buckle, which fastens to the support shaft from top to bottom. The two ends of the U-shaped buckle pass downward through the connecting plate and are then inserted together with a locking component.

[0012] A shock-absorbing assembly is installed between the connecting plates located inside the two sets of rollers, and the shock-absorbing assembly is connected and installed on the bottom surface of the car.

[0013] The structure of the shock absorption assembly is as follows: it includes a base mounted on the two side connecting plates, a shock absorption block installed on the top surface of the base above the connecting plates, and the top surface of the shock absorption block is installed with the car via the top plate; a vertical plate extends downward from the edge of the base between the connecting plates, and a gap is provided between the bottom end of the vertical plate and the inner top surface of the beam body for the lifting cable to pass through.

[0014] The crossbeam is a top beam installed on the outer top surface of the car. The top beam includes a beam body two with a U-shaped cross-section that opens downwards. The bottom edges of the two side plates of the beam body two extend outwards in opposite directions to form a connecting plate two. The shaft roller is housed at the opening of the beam body two, and the axially extending support shafts at both ends of the shaft roller are installed on the two side plates.

[0015] The side plate has a slot for mounting the support shaft from the outside to the inside. A support plate is fitted on the support shaft and is attached to the inner side of the side plate. It also includes a pressure plate attached to the outer side of the side plate. The pressure plate is located at the slot opening and fasteners are installed through the pressure plate, the side plate, and the support plate.

[0016] Shock-absorbing components are symmetrically installed on the two connecting plates at intervals on both sides. The structure of the shock-absorbing components includes a support plate that is simultaneously attached to the bottom surface of the two connecting plates on both sides, a shock-absorbing block installed on the top surface of the connecting plate, an upper plate installed on the top surface of the shock-absorbing block, and fasteners that pass through the upper plate, shock-absorbing block, connecting plate, and support plate from top to bottom and lock towards the top of the car.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This utility model simplifies the suspended lifting structure of the car by using a split-type car and crossbeam design, reduces space occupation, improves space utilization, and can effectively ensure shock absorption through shock-absorbing components, thus guaranteeing the actual user experience.

[0035] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0036] like Figure 2 and Figure 5 As shown, a suspended lifting structure for a car in this embodiment includes a car 10. A crossbeam is installed on the outer top or bottom surface of the car 10. A shock-absorbing component 3 is installed between the crossbeam and the car 10. Two symmetrically arranged rollers 2 are rotatably installed at both ends of the crossbeam. The axes of the two sets of rollers 2 are parallel to each other. A lifting cable is wound around the bottom of the rollers 2. The two ends of the lifting cable extend outward from the side of the corresponding rollers 2 and extend upward to form a lifting structure.

[0037] In this embodiment, the car 10 and the crossbeam are set as separate upper and lower parts. The lifting cable is wound around the upper shaft roller 2 of the crossbeam to realize the suspension lifting of the car 10. The overall structure is simplified and occupies less space.

[0038] The circumferential surface of the roller 2 has an outwardly extending annular ridge. The annular ridge, together with the end face of the roller 2, forms a concave space for accommodating the lifting cable, which effectively ensures the winding of the lifting cable on the roller 2 and prevents the lifting cable from shifting or detaching.

[0039] The lifting cable includes two or more cables spaced apart along the axial direction of the single set of rollers 2.

[0040] In this embodiment, two lifting cables can be arranged side by side on the shaft roller 2 to effectively ensure stable lifting of the car 10.

[0041] Example 1:

[0042] like Figure 3 and Figure 4 As shown, the crossbeam is a bottom beam 1 installed on the outer bottom surface of the car 10. The bottom beam 1 includes a beam body 11 with an upward-opening U-shaped cross-section. The two ends of the beam body 11 extend outwards in opposite directions to form a connecting plate 12. The shaft roller 2 is housed at the opening of the beam body 11. The support shafts 21 extending axially outwards at both ends of the shaft roller 2 are installed on the corresponding connecting plate 12, thus realizing the arrangement and installation of the shaft roller 2 relative to the bottom beam 1.

[0043] It also includes a U-shaped buckle 4, which fastens to the support shaft 21 from top to bottom. The two ends of the U-shaped buckle 4 pass downward through the connecting plate 12 and are fitted with locking parts 41. This realizes the assembly of the shaft roller 2 on the bottom beam 1, which is simple and convenient to operate.

[0044] A shock-absorbing assembly 3 is installed between the connecting plates 12 located inside the two sets of rollers 2, and the shock-absorbing assembly 3 is connected and installed on the bottom surface of the car 10.

[0045] In this embodiment, the shock absorption component 3 is connected between the car 10 and the bottom beam 1, which effectively ensures the shock absorption effect.

[0046] In one embodiment, the top surface of the shock-absorbing component 3 is higher than the highest point of the shaft roller 2, effectively ensuring the reliability of the overall structure.

[0047] The structure of the shock absorption assembly 3 is as follows: it includes a base 33 mounted on the connecting plates 12 on both sides, a shock absorption block 32 mounted on the top surface of the base 33 above the connecting plates 12, and the top surface of the shock absorption block 32 is mounted on the car 10 via the top plate 31; a vertical plate 331 extends downward from the edge of the base 33 between the connecting plates 12, and a gap is provided between the bottom end of the vertical plate 331 and the inner top surface of the beam body 11 for the lifting cable to pass through.

[0048] In this embodiment, not only is the installation of the damping component 3 on the bottom beam 1 achieved via the base 33, but it also helps to strengthen the structural strength and reliability of the bottom beam 1.

[0049] In this embodiment, not only is the suspended lifting of the car 10 achieved through the bottom beam 1 combined with the roller 2 and the shock absorption assembly 3, but the roller 2 and the shock absorption assembly 3 are also effectively arranged between the bottom beam 1 and the car 10, resulting in a compact and reasonable overall structural layout.

[0050] Example 2:

[0051] like Figure 6 and Figure 7 As shown, the crossbeam is the top beam 5 installed on the outer top surface of the car 10. The top beam 5 includes a beam body 51 with a U-shaped cross-section that opens downwards. The bottom edges of the side plates 52 on both sides of the beam body 51 extend outwards in opposite directions to form a connecting plate 53. The roller 2 is housed at the opening of the beam body 51. The support shafts 21 extending axially at both ends of the roller 2 are installed on the side plates 52, thereby realizing the effective layout of the roller 2 relative to the top beam 5 and ensuring the suspended lifting of the car 10.

[0052] The side plate 52 has a slot 521 for mounting the support shaft 21 from the outside to the inside. The support shaft 21 is fitted with a support plate 6, which is attached to the inner side of the side plate 52. It also includes a pressure plate 60 attached to the outer side of the side plate 52. The pressure plate 60 is located at the opening of the slot 521. Fasteners are installed through the pressure plate 60, the side plate 52, and the support plate 6 to achieve quick and reliable installation of the shaft roller 2 on the top beam 5.

[0053] In actual operation, the support plate 6 is first fitted onto the support shaft 21, and the support plate 6 is then fitted onto the top beam 5 along the slot 521 along the support shaft 21, so that the support plate 6 is fitted against the inner side of the side plate 52. The pressure plate 60 is then fitted against the outer side of the side plate 52. Finally, fasteners are locked onto the support plate 6 through the pressure plate 60 and the side plate 52, so as to realize the quick installation of the shaft roller 2 on the top beam 5.

[0054] like Figure 8 As shown, the support plate 6 located at both ends of the shaft roller 2 can be an integral U-shaped structure with the opening facing upward. The horizontal edge of the support plate 6 is folded upward or extended laterally to form a guide plate 61. The guide plate 61 is inclined upward along the outer circumference of the shaft roller 2.

[0055] Shock-absorbing components 3 are symmetrically and spaced on the two connecting plates 53 on both sides. The structure of the shock-absorbing components 3 is as follows: a support plate 35 is attached to the bottom surface of the two connecting plates 53 on both sides, a shock-absorbing block 32 is installed on the top surface of the connecting plate 53, and an upper plate 34 is installed on the top surface of the shock-absorbing block 32. Fasteners are installed from top to bottom through the upper plate 34, the shock-absorbing block 32, the connecting plate 53, and the support plate 35 toward the top of the car 10, thereby realizing the installation of the shock-absorbing components 3 between the top beam 5 and the car 10.

[0056] In this embodiment, the shock-absorbing component 3 is locked and fixed to the car 10 by fasteners. The top beam 5 has a through-and-fit structure relative to the fasteners. When the car 10 is suspended and lifted by the upper roller 2 of the top beam 5, the shock-absorbing component 3 achieves buffering and shock absorption.

[0057] This invention effectively simplifies the suspended lifting structure of the car, reduces space occupation, improves space utilization, and can effectively ensure shock absorption through shock absorption components, thus guaranteeing the actual user experience.

[0058] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
