Description

Technical Field

[0001] The utility model relates to elevator technology, in particular to a counterweight-main engine integrated machine beam machine room assembly. Background Art

[0002] Due to different specifications, different models, different well sites and other real situations, the elevator traction machine frame structure design in the prior art is also different, but although diverse, it is mainly used for main machine installation and shock absorption. For example, the base of an elevator traction machine with patent announcement number CN206927444U includes a traction machine, a guide wheel, a first base, and a second base. The traction machine is installed on the first base, and the first base is installed on the second base. It also includes a protective plate and a rope guard device. The rope guard device is provided with a through hole for the traction rope to pass through. The rope guard device is inclined along the traction rope between the traction wheel and the guide wheel. The upper end of the protective plate is connected to the second base, and the lower end of the protective plate extends to the wheel shaft of the guide wheel. The guide wheel is installed between the second base and the protective plate. The contact part between the guide wheel and the traction rope is provided with a rope stop plate that limits the position of the traction rope. Another example is an elevator traction machine installation base with patent announcement number CN205204578U, which includes a base and a heightening base. The base includes a mounting portion for mounting a motor and a supporting portion for supporting and balancing the force of the mounting portion. The supporting portion is arranged on one side of the main engine wheel. The motor is mounted on the mounting portion, the base is mounted on the heightening base, and when the heightening base is mounted on a load-bearing beam, the four corners of the heightening base mounted on the load-bearing beam are evenly stressed. And so on.

[0003] The traction machine base frame in the public technology is basically only used for positioning and bearing the traction machine, and the counterweight rope head plate assembly needs to be specially equipped with a machine beam fixed in the elevator shaft wall, or supported by the shaft wall and the traction machine frame. For passenger elevators, freight elevators, private elevators, etc. with smaller carrying capacity, the production cost is high and the installation process is complicated. In addition, the guide wheels in traditional technology are all set at the near point in the height direction of the traction machine base, the wire rope wrap angle is small, and the tensioning force is difficult to play a real role. Summary of the invention

[0004] The purpose of the utility model is to solve the above-mentioned problems and to provide a counterweight-main engine integrated machine beam room assembly, which has a common combined support for the counterweight rope head plate assembly and the traction machine base. Under the premise of ensuring structural strength, it simplifies the manufacturing and installation process, reduces the overall cost, increases the distance between the guide wheel and the traction wheel, and improves the wire rope wrap angle.

[0005] The above-mentioned technical problems of the present utility model are mainly solved by the following technical solutions: a counterweight-main engine integrated machine beam room assembly, comprising a beam with both ends extending into the elevator shaft wall, characterized in that the beam comprises two parallel arranged steel sections, both ends of the two steel sections are respectively provided with pads, and the pads are completely located in the elevator shaft wall; a traction machine is arranged on the plane of the beam, a car rope head plate assembly is provided on one side of the traction machine through a longitudinal connecting beam, and a counterweight rope head plate assembly is provided on a steel section on the other side of the traction machine; a guide wheel is fixed on the bottom surface of the beam.

[0006] In the aforementioned counterweight-main engine integrated machine beam room assembly, preferably, both ends of the wheel axle of the guide wheel are fixed to the bottom surfaces of two parallel arranged steel sections by U-bolts respectively.

[0007] In the aforementioned counterweight-main engine integrated machine beam room assembly, preferably, the counterweight rope head plate assembly is provided with a reinforcing plate at the steel section mounting surface, the reinforcing plate having a width greater than the steel section and a length capable of accommodating the counterweight rope head plate assembly.

[0008] In the aforementioned counterweight-main engine integrated machine beam room assembly, preferably, the center line of the guide wheel is located between the center line of the traction machine and the center line of the counterweight rope head plate assembly.

[0009] In the aforementioned counterweight-main engine integrated machine beam room assembly, preferably, an auxiliary connecting beam is provided between two parallel arranged steel sections where the counterweight rope head plate assembly is provided.

[0010] In the aforementioned counterweight-main engine integrated machine beam room assembly, preferably, a rope stop plate is provided on one side of the guide wheel facing the counterweight rope head plate assembly, and the rope stop plate is fixed on the steel section.

[0011] In the aforementioned counterweight-main engine integrated machine beam room assembly, preferably, the traction machine is positioned on the crossbeam through a frame, and a shock-absorbing pad assembly is provided between the frame and the crossbeam.

[0012] In the aforementioned counterweight-main engine integrated machine beam machine room assembly, preferably, the wire rope running planes of the traction machine, guide wheel and car rope head plate assembly are in the same plane.

[0013] This technical solution is based on the actual situation of small and medium-capacity elevators. Two parallel steel sections (such as I-beams) are used as crossbeams as the load-bearing body. The two ends of the crossbeam are positioned in the elevator shaft wall. The two steel sections are strengthened as a whole through longitudinal connecting beams, auxiliary connecting beams, etc., and the crossbeams and these auxiliary beams are used to install and configure functional parts, so as to obtain the maximum supporting force and the most ideal functional part installation space with the least number of components.

[0014] In this device, pads are respectively provided at both ends of the crossbeam to increase the bearing area of ​​the crossbeam support point and improve the stability of the crossbeam in the well wall; the traction machine, as the supporting body of this device, can determine its position on the crossbeam according to the position of the car, with the traction machine as the center, one of the functional parts, the car rope head plate assembly, is arranged on one side through the longitudinal connecting beam, and the second functional part, the counterweight rope head plate assembly, is arranged on the other side of the traction machine. The counterweight rope head plate assembly is directly arranged on one of the steel sections of the crossbeam, without the need for a separate counterweight shelf beam. Reinforcement plates are added to the steel section installation surface according to the stress conditions to ensure that the heavy rope head plate assembly works stably, safely and reliably.

[0015] This solution positions the guide wheel on the bottom surface of the beam, and its wheel axle is fixed by U-bolts. Its center line is located between the center line of the traction machine and the center line of the counterweight rope head plate assembly. That is, the installation position can be arbitrarily selected within this distance range, thereby obtaining a larger wire rope wrap angle, so that a larger rope center distance can be used.

[0016] In addition, the device can also fully meet the installation space and installation technical requirements of various auxiliary functional parts such as rope retaining plates and shock-absorbing pad components.

[0017] Therefore, compared with the prior art, the beneficial effects of the utility model are: a new counterweight rope head plate assembly and traction machine base combined support is designed, which not only ensures the structural strength and provides a safety foundation, but also simplifies the manufacturing and installation process, reduces the overall cost, and at the same time increases the distance between the guide wheel and the traction wheel, and can selectively increase the wire rope wrap angle, so that a larger value of the rope center distance can be used.

[0023] The technical solution of the utility model is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0024] like Figure 1 As shown, the present embodiment is a counterweight-main engine integrated machine beam room assembly, with a crossbeam 1 extending into the elevator shaft wall 3 at both ends as the supporting body, and the crossbeam is made of I-beam as the material of two parallel arranged steel sections 11, and pads 2 are respectively provided at the lower parts of the two ends of the two steel sections 11. When installed, the pads 2 are completely located in the elevator shaft wall 3.

[0025] The traction machine 9 is positioned on the plane of the cross beam 1 through the frame, and a shock-absorbing pad assembly 8 is provided between the frame and the cross beam 1. A car rope head plate assembly 10 is provided on one side of the traction machine 9 through the longitudinal connecting beam 4, and a counterweight rope head plate assembly 5 is provided on a steel section 11 on the other side of the traction machine 9. A guide wheel 13 is fixed on the bottom surface of the cross beam. The car rope head plate assembly 10 is provided on the longitudinal connecting beam 4, and its center line is in the same vertical plane as the center line of the wire rope groove of the guide wheel 13.

[0026] Therefore, taking the center line D of the car as the standard, the position relationship between the center lines of each functional part is as follows: Figure 2 As shown, on one side of the car center line D, from the shaft wall, are the counterweight center A of the counterweight rope head plate assembly 5, the guide wheel center line B, and the traction wheel center line C, and on the other side of the car center line D is the longitudinal connecting beam 4.

[0027] At the same time, it is ensured that the steel wire rope running planes of the traction machine 9, the guide wheel 13 and the car rope head plate assembly 10 are in the same plane.

[0028] The two ends of the wheel axle 12 of the guide wheel 13 are provided with tangential parts to form an axis mounting surface, which fits with the bottom surface of the steel section 11 through the tangential parts and is then fixed by U-bolts 7 respectively to ensure that the guide wheel 13 is horizontally stable on the bottom surfaces of the two parallel steel sections 11.

[0029] The counterweight rope head plate assembly 5 is provided with a reinforcing plate at the installation surface of the steel section 11, the width of which is greater than the steel section and the length of which can accommodate the counterweight rope head plate assembly. The counterweight rope head plate assembly 5 is provided with a total of 10 screw pull rods, which are divided into two groups, with 5 pull rods in each group, which are respectively installed in the supporting surfaces on both sides of the steel section 11, i.e., the center reinforcement of the I-beam.

[0030] Since the centerline of the guide wheel 13 is located between the centerline of the traction machine 9 and the centerline of the counterweight rope head plate assembly 5, the position of the wheel axle 12 of the guide wheel 13 can be selected in the horizontal direction to obtain the best wire rope wrap angle. A rope stop plate 6 is provided on one side of the guide wheel 13 facing the counterweight rope head plate assembly 5, and the rope stop plate 6 is directly fixed on the steel section 11.

[0031] In addition, an auxiliary connecting beam is added between the two parallel steel sections 11 where the counterweight rope head plate assembly 5 is provided to improve the overall structural strength of the beam.

[0032] Since the counterweight rope head plate assembly 5 and the traction machine 9 supporting beam 1 are an integrated structure, during installation, the entire support component is completely installed as long as the pads 2 at both ends of the beam 1 are aligned horizontally and fixed. The centerline position of the guide wheel 13 can be made in the factory according to the maximum wire rope wrap angle requirement, and only fine-tuning and installation are required on site, which not only reduces redundant auxiliary materials, but also greatly reduces production and time costs.

[0033] The above embodiments are illustrations of the present invention, not limitations of the present invention. Without departing from the principles of the present technical solution, any equivalent changes or equivalent modifications made in accordance with the technical ideas proposed by the present invention shall still fall within the scope of protection of the technical solution of the present invention.
