Description

Technical Field

[0001] This utility model relates to the field of elevator technology, specifically to an elevator car device. Background Technology

[0002] In the field of elevator technology, improving the comfort and stability of elevators during operation has always been an important research direction.

[0003] Referring to the elevator disclosed in application number 202223267436.6, this technical solution involves installing four shock-absorbing rubber clips on the top of the car. The car top frame has four angle irons for these clips, all extending downwards. Each angle iron corresponds to one shock-absorbing rubber clip. These shock-absorbing rubber clips reduce the mechanical vibration transmitted from the car top frame to the car, improving the comfort of the elevator operation. However, although this technical solution has achieved significant results in improving elevator operating comfort, some shortcomings have been exposed during actual installation. For example, because the car top frame requires four independent angle irons to be used with the shock-absorbing rubber clips one by one, this not only increases the complexity and workload of the installation process but may also increase the overall maintenance cost and complexity of the elevator due to the use of multiple independent components. Utility Model Content

[0025] Reference Figure 1-6 An elevator car assembly includes a car frame 1 and a car body 2 disposed within the car frame 1. The car frame 1 includes a car bottom bracket 11, car frame columns 12 disposed on the left and right sides of the car bottom bracket 11, and a car top frame 13 connected to the upper ends of the two car frame columns 12. The car body 2 includes a car bottom plate 21 mounted on the top of the car bottom bracket 11 using a car bottom buffer rubber 6, a car frame 22 disposed on the car bottom plate 21, and a car top plate 23 disposed on the top of the car frame 22. The car frame 22 is provided with a car wall module 24, and a buffer gap is left between the car frame 22 and the car frame columns 12. The car top plate 23 is located below the car top frame 13. The car top frame 13 includes two car top beams 131 corresponding to the front and rear sides of the car frame columns 12. The two car top beams 131 are connected by two rubber-fitting seats 3, which are respectively close to the two car frame columns 12 and are arranged opposite to each other.

[0026] Furthermore, the car roof plate 23 is provided with two rubber clamping assemblies located between two rubber clamping seats 3. Each rubber clamping assembly corresponds to one rubber clamping seat 3. The rubber clamping assembly includes two rubber clamping assembly parts 4 corresponding to the front and rear ends of the rubber clamping seat 3, respectively. Both the front and rear ends of the rubber clamping seat 3 are provided with mating corners 31. The rubber clamping assembly part 4 includes a rubber clamping fixing seat 41 fixed on the car roof plate 23, a rubber clamping plate 42 whose position is adjustable on the rubber clamping fixing seat 41, and a buffer rubber clamping 43 fixed on the rubber clamping plate 42. The buffer rubber clamping 43 is provided with a buffer recess that matches the mating corner 31.

[0027] The aforementioned structure uses a single adhesive clamping seat 3 to simultaneously engage two adhesive clamping assemblies 4. Compared to the traditional method that requires four independent adhesive clamping angle irons, this invention simplifies the installation process, reduces the workload, and improves installation efficiency. Furthermore, the reduced number of components decreases potential points of failure and maintenance needs, thereby lowering the overall maintenance cost and complexity of the elevator car.

[0028] In this embodiment, the adhesive retainer 41 has a first adhesive retaining elongated hole 411 extending from left to right in the length direction. The adhesive retaining plate 42 has at least two second adhesive retaining elongated holes 421 arranged from left to right and corresponding to the first adhesive retaining elongated hole 411. The length direction of the second adhesive retaining elongated holes 421 extends from front to back. A first adhesive retaining bolt assembly is inserted and connected to the first adhesive retaining elongated hole 411 in each second adhesive retaining elongated hole 421. The first adhesive retaining bolt assembly includes at least a first adhesive retaining adjusting bolt and a first adhesive retaining adjusting nut threaded onto the screw section of the first adhesive retaining adjusting bolt. After loosening the first adhesive retaining adjusting bolt and the first adhesive retaining adjusting nut, the adhesive retaining plate 42 can be moved left and right and back and forth to adjust the position of the buffer adhesive retaining 43 and the mating abutment 31, so that the buffering engagement effect between the adhesive retaining assembly and the adhesive retaining seat 3 is better. The first adhesive retaining bolt assembly is not shown in the accompanying drawings.

[0029] In this embodiment, the top view cross-sectional shape of the rubber-fitting seat 3 is U-shaped. The rubber-fitting seat 3 includes a middle part 32 and a connecting part 33 formed by bending from both ends of the middle part 32 towards the back side. The two connecting parts 33 are respectively connected to the two car top beams 131. The connecting corner between each connecting part 33 and the middle part 32 forms the mating angle 31. The rubber-fitting seat 3 is integrally formed, which has high structural stability. Moreover, the rubber-fitting seat 3 is simultaneously connected to the two car top beams 131, so that the rubber-fitting seat 3 and the car top beams 131 are mutually constrained, improving their structural stability.

[0030] In this embodiment, the car top beam 131 is provided with at least two third rubber-clamping elongated holes 1311 extending from top to bottom in the length direction, and the rubber-clamping seat connecting part 33 is provided with at least two fourth rubber-clamping elongated holes 331 extending from left to right in the length direction. Each third rubber-clamping elongated hole 1311 corresponds to one fourth rubber-clamping elongated hole 331. A second rubber-clamping bolt assembly is inserted and connected to the fourth rubber-clamping elongated hole 331 in each third rubber-clamping elongated hole 1311. The second rubber-clamping bolt assembly includes at least a second rubber-clamping adjusting bolt and a second rubber-clamping adjusting nut threaded on the screw section of the second rubber-clamping adjusting bolt. After loosening the second rubber-clamping adjusting bolt and the second rubber-clamping adjusting nut, the rubber-clamping mating seat 3 can be moved left and right and up and down to adjust the position of the buffer rubber 43 and the mating impact angle 31, so as to further improve the buffering mating effect of the rubber-clamping assembly and the rubber-clamping mating seat 3.

[0031] In a preferred embodiment, the car roof frame 13 is fitted with a protective cover 5 that surrounds the upper part and the front and rear sides of the two car roof beams 131. The protective cover 5 covers the rubber clamping seat 3 and is positioned above the buffer rubber clamp 43. The protective cover 5 is used to prevent external debris from falling onto the rubber clamping seat 3 and the buffer rubber clamp 43, thereby reducing the probability of damage to the rubber clamping seat 3 and the buffer rubber clamp 43.

[0032] In a preferred embodiment, there are four car bottom buffer pads 6 arranged in a rectangular pattern. The top of each car bottom buffer pad 6 is fixed with an upper buffer pad that is connected to the car chassis 21 by bolts, and the bottom is fixed with a lower buffer pad that is connected to the car bottom bracket 11 by bolts. This achieves the connection between the car bottom buffer pads 6 and the car chassis 21 and the car bottom bracket 11. The four car bottom buffer pads 6 can also effectively ensure the buffering quality of the car body 2.

[0033] In a preferred embodiment, the car bottom bracket 11 includes a chassis outer frame 111 fixedly connected to the inner side of the lower end of two car frame columns 12 on the left and right sides respectively, and two shock-absorbing rubber connecting beams 112 arranged in the chassis outer frame 111. The left and right ends of the two shock-absorbing rubber connecting beams 112 are fixedly connected to the chassis outer frame 111. The shock-absorbing rubber connecting beams 112 are connected to the buffer rubber lower plate, thereby realizing the connection between the car bottom buffer rubber 6 and the car top plate 23. Furthermore, two return rope wheel mounting beams 113 are fixedly connected inside the outer frame 111 of the chassis, arranged from front to right between the two shock-absorbing rubber connecting beams 112. The two return rope wheel mounting beams 113 are connected to two return rope wheel axles 114 arranged from left to right. The two return rope wheel axles 114 are respectively set close to the two car frame columns 12. Each return rope wheel axle 114 is provided with two steel belt return rope wheels 115 located inside the outer frame 111 of the chassis. The left and right sides of the outer frame 111 of the chassis are provided with rope wheel protrusion openings 1111 for the partial protrusion of the steel belt return rope wheels 115. Each rope wheel protrusion opening 1111 corresponds to one steel belt return rope wheel 115. The above structure allows the steel belt return rope wheels 115 to be mostly hidden inside the car bottom bracket 11, reducing the probability of damage to the steel belt return rope wheels 115. Furthermore, the return rope wheel mounting beam 113 also enhances the structural stability of the car bottom bracket 11 to a certain extent, ensuring the installation quality of the car bottom bracket 11.

[0034] In this embodiment, the side of the car frame column 12 facing away from the car body 2 is a guide rail clearance groove. An electronic safety clamp 7 is provided in the guide rail clearance groove. The electronic safety clamp 7 is used to stop the elevator car device in conjunction with the elevator guide rail when the elevator car device is running at overspeed. The use of electronic safety clamp 7 eliminates the need for a transmission-driven safety clamp lifting mechanism, thereby reducing the volume of the elevator car.

[0035] In this embodiment, the car top frame 13 is provided with two upper roller guide shoes corresponding to the top of the two car frame columns 12 respectively, and the bottom of the outer square frame 111 of the car bottom bracket 11 is provided with two lower roller guide shoes corresponding to the bottom of the car frame columns 12 respectively. The upper roller guide shoes and the lower roller guide shoes are both used to cooperate with the elevator guide rail for guidance.

[0036] The above description is only a preferred embodiment of the present utility model. Any technical solution that achieves the purpose of the present utility model by essentially the same means shall fall within the protection scope of the present utility model.
