Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to a passenger elevator load-bearing beam installation structure. Background Art

[0002] Referring to the patent document with application number CN202320329115X, it discloses an installation structure of a counterweight load-bearing beam of an elevator with a machine room, including a main engine base load-bearing beam assembly installed at both ends in the elevator machine room and a counterweight load-bearing beam of the elevator with a machine room, wherein the main body is arranged on the side of the main engine base load-bearing beam assembly, one end of the main body is installed on the side of the main engine base load-bearing beam assembly, and the other end is installed on the side wall of the elevator machine room through a channel steel.

[0003] The disadvantages of this type of load-bearing beam structure: it takes up a large space. When the hoistway is small, the net size of the machine room is small. After the main and auxiliary load-bearing beams are placed, there is not enough space for the main engine and control cabinet, resulting in no maintenance space, which leads to the failure of the elevator acceptance and the problem of complex structure. In addition, when the elevator hoistway is built, under normal circumstances, the machine room door and the hall door are placed in the same direction, which can prevent the machine room door from being exposed to rain indoors. However, when the elevator is rear-counterweighted, the load-bearing beam will interfere with the machine room door, resulting in the inability to open the door, and non-standard rectification or lifting the door is required. Utility Model Content

[0004] The utility model aims to provide a passenger elevator load-bearing beam installation structure for the deficiencies in the prior art, and the use of the structure can solve the problem of complex structure.

[0005] The purpose of the utility model is achieved through the following technical solutions: The application provides a passenger elevator load-bearing beam installation structure, including a main load-bearing beam, which is arranged in the middle of the well along the longitudinal direction of the well; two auxiliary load-bearing beams are arranged at intervals along the longitudinal direction of the well, and each auxiliary load-bearing beam is arranged transversely along the well, one end of the auxiliary load-bearing beam is fixedly installed on the right side of the main load-bearing beam, and the other end is fixedly installed on the side wall of the well; a car rope head plate, which is fixedly installed on the left side of the main load-bearing beam; a counterweight rope head plate, which is fixedly installed on the side of the auxiliary load-bearing beam; and a load-bearing device, which is fixedly installed between the two auxiliary load-bearing beams.

[0006] Among them, the car rope head plate is fixed on the main load-bearing beam by welding.

[0007] Among them, the counterweight rope head plate is fixedly installed on the secondary load-bearing beam by welding.

[0008] Among them, the main load-bearing beam is an I-shaped channel steel structure.

[0009] Wherein, the secondary load-bearing beam is one of an I-shaped channel steel structure or a U-shaped channel steel structure.

[0010] Among them, the load-bearing device includes a main frame, a pair of longitudinal beams and a pair of cross beams. The pairs of longitudinal beams are arranged at intervals in the transverse direction on the top surface of the auxiliary load-bearing beams, and the pairs of cross beams are arranged at intervals in the longitudinal direction on the top surface of the longitudinal beams. The main frame is fixedly installed on the top surface of the cross beams, and shock-absorbing rubber is provided between the longitudinal beams and the auxiliary load-bearing beams.

The car rope head plate is placed on the side of the main load-bearing beam, and the counterweight rope head plate is placed on the side of the auxiliary load-bearing beam. The entire load-bearing beam layout is arranged in an "Y" shape. Compared with the prior art, the use of one main load-bearing beam is reduced, thereby reasonably reducing the use of raw materials while reducing space occupancy, simplifying the load-bearing beam structure, and solving the problem of complex structure in the past.

[0013] The main load-bearing beam is arranged horizontally to the middle of the shaft, so that there is enough space between the main load-bearing beam and the wall for placing the control cabinet, which can meet the operating space requirements of national standards.

[0014] When the rear is counterweighted, the machine room door and the hall door are in the same direction and will not interfere with the load-bearing beam. There is no need to change the door opening in a non-standard manner, nor to consider moving the load-bearing beam in a non-standard manner.

[0015] Compared with the traditional structure, the reduction of one main load-bearing beam makes the installation more convenient and quick, and the installation efficiency is also improved to a certain extent. BRIEF DESCRIPTION OF THE DRAWINGS

Two auxiliary load-bearing beams 3 are arranged at intervals along the longitudinal direction of the shaft 1, and each auxiliary load-bearing beam 3 is arranged transversely along the shaft 1.

[0023] As an improvement, one end of each secondary load-bearing beam 3 is fixedly installed on the right side of the main load-bearing beam 2, and the other end is fixedly installed on the side wall of the shaft 1. The car rope head plate 4 is fixedly installed on the left side of the main load-bearing beam 2, and the counterweight rope head plate 5 is fixedly installed on the side of the secondary load-bearing beam 3 located below. In addition, the load-bearing device 6 is fixedly installed between the two secondary load-bearing beams 3.

[0024] As a preferred solution, the car rope head plate 4 is fixedly installed on the main load-bearing beam 2 by welding. The welding method has a sufficiently high connection strength to ensure the working stability of the load-bearing beam. Similarly, the counterweight rope head plate 5 is fixedly installed on the secondary load-bearing beam 3 by welding.

[0025] As a preferred solution, the main load-bearing beam 2 is an I-shaped channel steel structure, specifically, an I-shaped steel of model 22-25 can be used, and the secondary load-bearing beam 3 is an I-shaped channel steel structure or a U-shaped channel steel structure, specifically, a channel steel of model 14 can be used.

[0026] Please see Figure 2 The load-bearing device 6 includes a main frame 63, a pair of longitudinal beams 61 and a pair of cross beams 62.
