Elevators play an important role in high-rise buildings, not only making it more convenient for people to go up and down the stairs, but also helping people transport goods, etc.
[0003] During the design and installation of elevators, the size of the hoistway space has a very important impact on the operation of the elevator. Due to the national standard requirements for elevator maintenance space, when the top space of the hoistway is small, the elevator structure with car bottom wheels is generally selected.
[0004] In the elevator structure using car bottom wheels, the space occupied by the shaft pit is larger than that when the rope pulley is installed on the car top. Therefore, how to reduce the space occupied by the shaft pit by optimizing the elevator structure has become a research direction for this type of elevator using car bottom wheel structure.
[0005] The prior art discloses a car chassis frame, wherein two car chassis side beams, a car chassis frame front beam and a car chassis frame rear beam are enclosed to form a car chassis frame, and a reinforcing rib is arranged between the two car chassis side beams to ensure the necessary strength, and the reinforcing rib is arranged above the two car chassis side beams. The car chassis upper inclined beam, the car chassis lower inclined beam and two car chassis wheel vertical plates are enclosed to form a car chassis wheel installation frame. The installation frame is arranged below the car chassis frame and the reinforcing rib, the car chassis wheel is installed on the car chassis wheel vertical plate, and the shockproof rubber is placed on the top of the car chassis frame.
[0006] It has the following technical problems:
[0007] The overall height of the car chassis includes the superposition of the car chassis frame, the mounting frame and the car chassis anti-vibration rubber, which makes the overall height of the car chassis relatively high and difficult to apply to scenes with shallow pit depth. Utility Model Content
[0008] In view of the problems existing in the prior art, the purpose of the utility model is to provide an inclined beam embedded elevator car frame, which has a relatively small overall height and can be applied to scenes with a shallow pit depth.
[0009] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0011] The upper inclined beam and the reinforcing ribs of the car floor are respectively arranged below the side beams of the car floor and fixed to the side beams of the car floor, and the reinforcing ribs are passed through the upper inclined beam of the car floor;
[0012] The shock-absorbing rubber is arranged on the upper surface of the bottom of the side beam of the car bottom.
[0013] Furthermore, a car bottom frame is provided above the upper inclined beam of the car bottom, and the car bottom frame comprises two opposite car bottom side beams, a car bottom frame front beam and a car bottom frame rear beam.
[0014] Furthermore, the car bottom side beams, the car bottom frame front beams and the car bottom frame rear beams are all bent C-shaped parts.
[0015] Furthermore, a plurality of shockproof rubbers are provided, and the plurality of shockproof rubbers are spaced apart and arranged on the side beams of the car bottom and the front beam of the car bottom frame.
[0016] Furthermore, three reinforcing ribs are provided, and the three reinforcing ribs are respectively passed through the middle and both ends of the upper inclined beam of the car bottom.
[0017] Furthermore, the upper inclined beam of the car floor is connected to the side beams of the car floor by bolts.

[0019] Furthermore, a mounting frame is provided below the car bottom side beams, the mounting frame comprising an upper car bottom oblique beam, a lower car bottom oblique beam and two car bottom wheel uprights, and the car bottom wheel uprights are provided with car bottom wheels.
[0020] In general, the utility model has the following advantages:
[0021] The position of the reinforcing ribs is improved from being set above the side beams of the car bottom to being set below the side beams of the car bottom, thereby providing installation space for the downward movement of the shockproof rubber. The position of the shockproof rubber can be changed from the top of the side beams of the car bottom to the upper surface of the bottom of the side beams of the car bottom, thereby eliminating the influence of the height of the shockproof rubber on the overall height. In addition, the structural design of the reinforcing ribs passing through the upper inclined beams of the car bottom is adopted, so that the reinforcing ribs will not increase the overall height of the car bottom frame. The utility model reduces the overall height of the car bottom frame by moving the position of the shockproof rubber downward and embedding the reinforcing ribs into the upper inclined beams of the car bottom, so that it can be used in scenes with shallow pit depths, expanding the installation range of elevators, and has great promotion value.

[0030] The utility model will be further described in detail below.
[0031] like Figure 1 , Figure 2 As shown, an inclined beam embedded elevator car chassis frame includes a car chassis frame, a mounting frame, reinforcing ribs 3, shockproof rubber 4, etc.
[0032] The car bottom frame is formed by two opposite car bottom side beams 11, a car bottom frame front beam 12 and a car bottom frame rear beam 13. Preferably, the car bottom side beams 11, the car bottom frame front beam 12 and the car bottom frame rear beam 13 are all bent C-shaped parts.
[0033] The mounting frame is arranged below the car bottom frame, and is formed by the upper car bottom oblique beam 22, the lower car bottom oblique beam 23 and two opposite car bottom wheel vertical plates 21. The car bottom wheel vertical plates 21 are provided with car bottom wheels 5.
[0034] The upper inclined beam 22 of the car floor and the reinforcing ribs 3 are respectively arranged below the car floor side beams 11 and fixed to the car floor side beams 11 .
[0035] The reinforcing rib 3 is arranged below the car bottom side beam 11 , providing installation space for the downward movement of the anti-vibration rubber 4 .
[0036] A plurality of shockproof rubbers 4 are provided, and the plurality of shockproof rubbers 4 are arranged at intervals on the car bottom side beams 11 and the car bottom frame front beams 12 .
[0037] The reinforcing ribs 3 are passed through the upper inclined beam 22 of the car bottom, and the reinforcing ribs 3 are cleverly avoided from increasing the overall height through the embedded installation method.
[0038] In this embodiment, three reinforcing ribs 3 are provided, and the three reinforcing ribs 3 are respectively passed through the middle and both ends of the upper inclined beam 22 of the car bottom.
[0039] The upper oblique beam 22 of the car floor is connected to the side beam 11 of the car floor by bolts. The reinforcing rib 3 is fixed to the upper oblique beam 22 of the car floor by welding.
[0040] In the prior art, the overall height of the car chassis includes the superposition of the car chassis frame, the mounting frame and the car chassis anti-vibration rubber 4, which makes the overall height of the car chassis relatively high and difficult to be applied to scenes with shallow pit depth.
[0041] The utility model improves the position of the reinforcing rib 3 from being arranged above the car bottom side beam 11 to being arranged below the car bottom side beam 11, thereby providing installation space for the position of the shockproof rubber 4 to move downward, and the position of the shockproof rubber 4 can be changed from the top of the car bottom side beam 11 to the upper surface of the bottom of the car bottom side beam 11, eliminating the influence of the height of the shockproof rubber 4 on the overall height. In addition, the structural design of the reinforcing rib 3 passing through the upper inclined beam 22 of the car bottom is adopted, so that the reinforcing rib 3 does not increase the overall height of the car bottom frame, eliminating the influence of the height of the reinforcing rib 3 on the overall height.
[0042] In summary, the utility model reduces the overall height of the car bottom frame by moving the anti-vibration rubber 4 downward and embedding the reinforcing rib 3 into the inclined beam 22 on the car bottom, so that it can be used in scenes with shallow pit depth, expands the installation range of the elevator, and has great promotion value.
