[0029] This utility model provides a front column for a car, wherein the front column 3000 is located on the two front sides of the car, and its upper and lower parts are fixed to the car top and car bottom respectively.
[0030] like Figure 1 As shown, the front pillar 3000 of the car has an overall L-shaped structure. The front pillar 3000 of the car includes a side part 3007 and a front part 3008, which are arranged symmetrically to each other.
[0031] The side portion 3007 includes a front pillar side opening groove 3001, a first front pillar side nut groove 3002, and a second front pillar side nut groove 3003; the front portion 3008 includes a first front pillar front nut groove 3004, a second front pillar front nut groove 3005, and a front pillar front opening groove 3006.
[0032] like Figure 1 As shown, the front pillar side opening groove 3001 and the first front pillar side nut groove 3002 overlap in the width direction. The overlap in the width direction means that the projections of the front pillar side opening groove 3001 and the first front pillar side nut groove 3002 overlap along the width direction. One end of the front pillar side opening groove 3001 along the depth direction is connected to one end of the first front pillar side nut groove 3002 along the depth direction. The other end of the front pillar side opening groove 3001 along the depth direction and the other end of the first front pillar side nut groove 3002 along the depth direction are separated by the first protrusion 3009. The second front post front nut groove 3005 and the front post front opening groove 3006 coincide in the depth direction; this coincidence in the depth direction means that the projections of the second front post front nut groove 3005 and the front post front opening groove 3006 overlap along the depth direction. One end of the second front post front nut groove 3005 along the width direction is connected to one end of the front post front opening groove 3006 along the width direction, and the other end of the second front post front nut groove 3005 along the width direction is separated from the other end of the front post front opening groove 3006 along the width direction by the second protrusion 3010. The depth direction can also be referred to as the front-rear direction.
[0033] A third protrusion 3011 is arranged in the nut groove 3003 on the second front column side, and a fourth protrusion 3012 is arranged in the nut groove 3004 on the first front column. Bolt hole guide grooves 3013 and 3014 are respectively opened next to the nut groove 3003 on the second front column side and the nut groove 3004 on the first front column for hole positioning. When the fastener is fixed by drilling along the guide groove on the front column, the bolt head or nut located in the column will be restricted from rotation by the third protrusion 3011 and the fourth protrusion 3012, so no additional holding is required.
[0034] The front column side opening groove 3001 and the front column front opening groove 3006 are used to insert glass or photoelectric safety devices or install fixed brackets.
[0035] The first front column side nut groove 3002 and the second front column side nut groove 3003; the first front column front nut groove 3004 and the second front column front nut groove 3005 are all used to install nut strips that connect to the elevator car top and car bottom. In addition to the locations where nut strips connect to the car top and car bottom, the first front column side nut groove 3002 and the second front column front nut groove 3005 can also be used for convenient cable installation.
[0036] like Figures 2-5 As shown, this utility model also provides an elevator, which includes a track frame 1 and a car 2, and the front column 3000 of the car is the column structure of the car 2.
[0037] The track frame 1 includes a frame column 11, from which a car guide rail 112 extends;
[0038] The car 2 includes a floor, a rear column 21, and a front column 3000; there are two rear columns 21 and two front columns 3000, for a total of four columns distributed along the circumference of the car. The floor is used to carry people and / or goods; a car guide assembly 3 extends from the car 2; the car guide rail 112 is connected to the car 2 through the car guide assembly 3.
[0039] The car guide assembly 3 is located at 2 ends on the same side of the car; and / or the car 2 is a single-layer structure that accommodates and bears the load.
[0040] like Figure 4 As shown, the side projection of the frame column 11 overlaps with the side projection of the rear column 21 of the car. The side projection of the car guide assembly 3 also overlaps with the side projection of the rear column 21 of the car.
[0041] The car guide assembly 3 is a roller structure; the rear column 21 of the car includes the rear column body 211 and the car guide assembly mounting position 212; the car guide assembly 3 includes a mounting block 31 and car guide rollers 32, and there are 3 car guide rollers 32. The 3 car guide rollers 32 are mounted on the car guide assembly mounting position 212 through the mounting block 31; two of the car guide rollers 32 are located on both sides of the car guide rail 112 respectively, clamping the car guide rail 112; the other car guide roller 32 is arranged perpendicularly to the other car guide rollers 32 and is attached to the end face of the car guide rail.
[0042] like Figure 3 As shown, the vertical projection of the frame column 11 is U-shaped. The frame column 11 is provided with the following in sequence: counterweight sealing plate groove 101, light strip groove 102, counterweight guide wheel groove 103, first sealing plate or glass mounting groove 104, first splicing nut strip groove 105, first wire groove 106, first anti-fastener rotation limiting groove 107, second wire groove 1061, second anti-fastener rotation limiting groove 1071, second splicing nut strip groove 1051, and second sealing plate or glass mounting groove 1041.
[0043] like Figure 5 As shown, the vertical projection of the rear column body 211 of the car is an L-shaped structure. The rear column body 211 of the car is provided with a rear column side opening groove 213, a rear column first side nut groove 214, a car guide component mounting position 212, a rear column rear nut groove 215, and a column rear opening groove group in sequence. The rear column side opening groove 213 is also provided with a rear column second side nut groove 216. The column rear opening groove group includes a rear column first rear opening groove 217 and a rear column second rear opening groove 218 arranged in parallel with each other.
[0044] The car guide component mounting position 212 is located at the corner of the L-shaped structure. The car guide component mounting position 212 is also an L-shaped structure, and the long side of the L-shape of the car guide component mounting position 212 is an open structure.
[0045] Because the rear column body 211 of the car has a large cross-sectional area, principal moment of inertia and bending section modulus, and its cross-section is provided with a total of 6 nut slots for side connection (one in the depth and one in the width direction of the car guide component mounting position 212), the rear column rear nut slot 215 and the rear column second rear opening slot 218, the car guide component mounting position 212 has multiple locking positions and reasonable distribution, and the locking is firm. Therefore, when it is locked with the car bottom and possibly the car top, the car can directly bear and transmit the load.
[0046] The elevator design of this utility model includes a car guide rail extending from the frame column and a car guide assembly extending from the car. By using the car guide assembly to connect the car guide rail to the car column, the direct connection between the track frame and the car column is achieved, eliminating the need for a separate car frame and avoiding the cumbersome production and assembly process caused by the need to produce a separate car frame in the prior art.
[0047] Compared to existing technologies that require a separate car frame, this new elevator design eliminates the need for a separate car frame. This allows for an overlap between the side projections of the frame columns and the car columns, meaning the track frame and car columns are closer together. Consequently, the car can have greater depth and area. In other words, this new design increases the car's area by increasing its depth.
