Description

Novel shockproof car frame

Technical Field

The utility model relates to the technical field of elevators, in particular to a novel shockproof car frame.

Background

The elevator mainly comprises a machine room, a hoistway, a pit, a lift car frame and a landing according to the structure.

Present elevator car frame every side is the single-upright-column design, and it is higher to processing precision requirements such as the mill bends and welds, and simultaneously when assembling each part to the on-the-spot installer, relative position accuracy control is good the accuse, because each spare part mounted position need just can eliminate processing and assembly error through the gasket adjustment, so dimensional control is not good very easily causes structural stress in the installation, causes the elevator to shake altogether and influences elevator comfort level. Therefore, in order to reduce the vibration of the car and improve the comfort of passengers during the operation of the elevator, a car frame capable of preventing the vibration of the elevator is urgently needed.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a novel shockproof car frame to solve the problem that the conventional car frame is easy to cause structural stress in the installation process and cause the common shock of an elevator.

In order to solve the technical problems, the utility model provides the following technical scheme: the utility model provides a novel sedan-chair frame takes precautions against earthquakes, includes sedan-chair frame upper beam, four stands and bottom bracket, four the stand mirror image sets up in the both sides of bottom bracket, and it lies in the bottom bracket and leaves the clearance between two stands with one side, and lies in the bottom bracket and pass through connecting piece fixed connection between two stands with one side, four the top of stand with upper beam fixed connection, the upper beam is equipped with returns the rope sheave and leads boots.

The utility model has the following working principle and beneficial effects: this scheme is through two stands of equal fixed connection in the both sides of lower carriage, two stands of same one side at the lower carriage pass through connecting piece with two stand fixed connection, consequently, four tie points have between lower carriage and the stand, can effectively ensure the stability and the stationarity of lower carriage, the difficult slope that takes place, adopt four column type designs simultaneously, the stability of car frame when sliding from top to bottom in the elevartor shaft has been increased, can reduce the elevator that two column type car framves arouse because of the structural stress condition and shake altogether, the passenger travelling comfort when taking the elevator has been promoted.

Furthermore, the top ends of the four upright posts are vertical to the upper beam of the car frame, and the lower ends of the four upright posts are vertical to the lower bracket. Its purpose, through this kind set up stand and sedan-chair frame upper beam and bottom bracket openly be connected, there is not the fit clearance problem in the assembling process, so need not the gasket adjustment, the assembly requirement in the installation that has significantly reduced has eliminated the structure and has assembled stress.

Further, the lower bracket is integrally welded and formed. Its purpose, through this kind of setting, can ensure the bulk strength of bottom bracket, compare with the bottom bracket of current combination formula, have better stability and intensity, be difficult for taking place vibrations in the car operation.

Furthermore, the number of the return rope wheels arranged on the upper beam of the car frame is two. The steel rope of the traction machine can be wound around the two diversion sheaves through the arrangement, so that the wrap angle reaches 180 degrees, the traction force in the whole traction system can be effectively increased, and the safety of the elevator is improved.

Furthermore, the number of the connecting pieces for connecting the stand columns is two, the two connecting pieces are respectively arranged on the upper portion and the lower portion of the stand columns, and the connecting pieces are fixedly connected with the stand columns through bolts. Its purpose can be through connecting in stand upper portion and connecting piece of lower part through this kind of setting, fixes two stands, strengthens its stability, avoids appearing vibrations.

fig. 2 is a schematic structural view of the right side view of the novel shockproof car frame.

Detailed Description

The following is further detailed by way of specific embodiments:

reference numerals in the drawings of the specification include: the elevator car frame comprises an upper beam 1 of the car frame, a vertical column 2, a rope return wheel 3, a lower bracket 4, a guide shoe 5, a connecting piece 6 and a safety gear 7.

The embodiment is substantially as shown in figures 1 and 2:

the utility model provides a novel sedan-chair frame takes precautions against earthquakes, including sedan-chair frame upper beam 1, four stands 2 and bottom bracket 4, bottom bracket 4 is whole welding forming, four 2 mirror images of stand set up the both sides at bottom bracket 4, it is located bottom bracket 4 and leaves the clearance between two stands 2 with one side, and lie in bottom bracket 4 and pass through 6 bolted connection of two the same connecting pieces between two stands 2 with one side, two connecting pieces 6 set up upper portion and lower part at stand 2 respectively, four stands 2's top and upper beam fixed connection, the both ends of upper beam all are equipped with returns rope sheave 3 and lead boots 5, two lead boots 5 and are located the stand 2's that is located bottom bracket 4 both sides respectively top. Two diversion sheaves are positioned on the lower surface of the car frame upper beam 1, two rotating shafts are arranged on a fixed plate which is fixedly connected with the lower surface of the car frame upper beam 1, and the two diversion sheaves are respectively and rotatably connected on the two rotating shafts. The lower bracket 4 is fixedly connected with a safety gear 7, and the safety gear 7 is positioned between the two upright posts 2.

The top ends of the four stand columns 2 are perpendicular to the upper beam 1 of the car frame, the stand columns 2 are connected with the upper beam 1 of the car frame through 8.8-level high-strength bolts, the low ends of the four stand columns 2 are perpendicular to the lower bracket 4, and the low ends of the four stand columns 2 are connected with the lower bracket 4 through 8.8-level high-strength bolts.

The specific implementation process is as follows:

this scheme is through two stands 2 at the equal fixed connection in both sides of lower bracket 4, two stands 2 with one side at lower bracket 4 pass through connecting piece 6 with two stands 2 fixed connection, consequently, four tie points have between lower bracket 4 and the stand 2, can effectively ensure the stability and the stationarity of lower bracket 4, the difficult slope that takes place, adopt four stand 2 formula designs simultaneously, the stability of car frame when sliding from top to bottom in the elevartor shaft has been increased, can reduce the elevator that two stand 2 formula car framves arouse because of the structural stress condition and shake altogether, the passenger travelling comfort when taking the elevator has been promoted.
