Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to a 2:1 elevator main engine layout structure. Background Technique

[0002] There are many 1:1 elevators in the existing old elevators on the market. When the original old elevator is transformed into a 1:1 elevator, the original machine mounting beam in the machine room can be retained during the transformation. Only a new machine base is added to the original machine mounting beam to install the new main engine. There is no need for civil construction in the machine room, the transformation time is short, and the noise and dust are small. However, because the torque of the 1:1 main engine is large and the price is much higher than that of the 2:1 main engine, the transformation cost is also correspondingly higher. When most of the existing 2:1 transformations are carried out, due to the large difference between its machine room layout structure and the original old elevator, during the transformation, it is required to remove the original machine mounting beam and other machine room components, re-arrange the machine mounting beam and drill rope holes, which requires a lot of civil construction, has many bad effects such as more noise and dust, and also damages the original machine room civil engineering to a certain extent. Compared with retaining the machine mounting beam, the transformation time is also increased. To solve the above problems, a 2:1 transformation scheme that retains the old elevator machine mounting beam is needed, so that the layout of its machine mounting beam is exactly the same as that of the old 1:1 elevator. The machine room transformation can be completed only by replacing the new machine base and other components on site, which will have greater advantages. Summary of the Utility Model

[0030] The following further details the present utility model with reference to the accompanying drawings.

[0031] As Figures 5 to 12 shown, a 2:1 elevator main machine layout structure includes a main machine 1, a main machine mounting base 2, and a machine mounting beam 3. Among them: the machine mounting beam 3 retains the original old elevator machine mounting beam and its layout unchanged, and two machine mounting beams 3 are arranged in the machine room; the main machine mounting base 2 is mounted on the machine mounting beam 3 through anti-vibration rubber 4; the main machine 1 is installed on the main machine mounting base 2; a guide wheel 5, a counterweight rope socket plate 6, and a car rope socket plate 7 are respectively installed on the main machine mounting base 2; steel wire ropes 8 pass through the machine mounting beam 3 on both sides according to the quantity and are respectively threaded through the counterweight rope socket plate 6 and the car rope socket plate 7 through rope socket tie rods 9; a steel wire rope clamp 10 is clamped on the machine mounting beam 3; the steel wire rope 8 passes through the through hole 107 of the steel wire rope clamp 10 to limit its position and ensure that it does not collide with the machine mounting beam 3. The present utility model is supported by two machine mounting beams, which is completely consistent with the layout of the old 1:1 elevator. The machine room renovation can be completed only by replacing the new base, etc. on site. The renovation method is the same as that of the 1:1 elevator renovation. The machine mounting beam can be retained to avoid the civil engineering construction of demolishing the original old elevator machine mounting beam, and the 2:1 renovation scheme can be used to adopt a smaller main machine with lower cost, and the renovation has greater advantages. The renovation method of the present utility model completely retains the old elevator machine room beam, has a short construction time for renovation, and makes the renovation faster, more environmentally friendly, and lower in cost.

[0032] It should be noted that the hoisting beam retains the original old hoisting beam and its layout unchanged, and the layout of two hoisting beams is set in the machine room; the main machine installation base 2 is erected on the original old hoisting beam, and four anti-vibration rubbers are arranged between them to damp the main machine 1; referring to Figure 1 , for the old ladder 1:1 hanging hoisting beam, two-beam layout is adopted, and the car center and the counterweight center are between the two hoisting beams, and the distances to the centers of the two beams are L1 and L2 respectively. For different elevator brands and specifications, the values of L1 and L2 may be different.

[0033] Specifically, in the solution of this embodiment, the car center 11 and the counterweight center 12 are located between the two hoisting beams. The distance from the car center 11 to the center of one of the hoisting beams is L1, and the distance from the counterweight center 12 to the center of the other hoisting beam is L2; a car deflecting sheave 13 is arranged at the car center 11; a counterweight deflecting sheave 14 is arranged at the counterweight center 12.

[0034] Referring to Figures 2 to 4 , when converting from the old ladder 1:1 hanging to 2:1 hanging, since deflecting sheaves are added to both the counterweight and the car, the diameters of the car deflecting sheave 13 and the counterweight deflecting sheave 14 are mostly 400 mm. The car deflecting sheave 13 is arranged at the center of the car and the counterweight deflecting sheave 14 is arranged at the center of the counterweight. When the value of L1 or L2 is about half of the diameter of the car deflecting sheave 13 or the counterweight deflecting sheave 14 (for example, L1 = 200 mm), at this time, the rope winding of the steel wire rope 8 will interfere with the hoisting beam. Normally, the hoisting beam will be replaced to avoid this. In this solution, the steel wire rope 8 passes through the hoisting beam on both sides according to the quantity and is respectively passed through the counterweight rope socket plate 6 and the car rope socket plate 7 through the rope head pull rod 9. The steel wire rope splint 10 is used to clamp the hoisting beam 3, and the steel wire rope 8 is passed through the hole of the steel wire rope splint 10 to limit its position, ensuring that it does not collide with the hoisting beam 3, so as to achieve the purpose of retaining the original hoisting beam.

[0035] Specifically, in the solution of this embodiment, the car rope socket plate 7 and the lower rope point 15 of the main machine wheel are respectively arranged near the anti-vibration rubbers 4 on both sides; the counterweight rope socket plate 6 and the lower rope point 16 of the guide sheave are respectively arranged near the anti-vibration rubbers 4 on both sides. It should be noted that when adopting Layout 1, the car rope socket plate 7 and the lower rope point 15 of the main machine wheel are respectively arranged near the anti-vibration rubbers 4 on both sides, so that the forces on both sides of the rubber are basically the same, and the deformation force and the vibration of the main machine received by the car-side main machine installation frame will be improved; after the transformation, the counterweight rope socket plate 6 and the lower rope point 16 of the guide sheave are respectively arranged near the anti-vibration rubbers 4 on both sides, so that the forces on both sides of the rubber are basically the same, and the deformation force and the vibration of the main machine received by the counterweight-side main machine installation frame will be improved.

[0036] Specifically, in the solution of this embodiment, the wire rope clamp 10 is composed of a first wire rope clamp 101, a second wire rope clamp 102, a third wire rope clamp 103 and a fourth wire rope clamp 104; the second wire rope clamp 102 and the third wire rope clamp 103 are both provided with limit clamping openings 105 for clamping the bottom of the machine mounting beam 3. It should be noted that the limit clamping opening 105 is used to clamp the bottom of the machine mounting beam 3 to prevent the wire rope clamp from colliding with the machine mounting beam 3 during operation and also prevent the wire rope clamp from falling to the counter pulley, causing danger.

[0037] Specifically, in the solution of this embodiment, the wire rope clamp is bound to the machine mounting beam 3 by a secondary protection device to prevent the wire rope clamp with ineffective clamping from falling downward along the wire rope to the counter pulley, causing danger.

[0038] Specifically, in the solution of this embodiment, the wire rope clamp 10 is provided with locking bolt holes 106, and the locking bolt holes 106 cooperate with the locking bolts 108 for locking between the first wire rope clamp 101, the second wire rope clamp 102, the third wire rope clamp 103 and the fourth wire rope clamp 104.

[0039] In summary, the present invention provides a 2:1 elevator main engine layout structure, and its transformation method completely retains the old elevator machine room beam. The transformation construction time is short, making the transformation faster, more environmentally friendly and lower in cost. The mechanical structure adopted by the present invention is simple, the components are universal, the processing technology is simple, and the cost is low. At the same time, the operation performance and use safety of the transformed elevator are ensured.

[0040] The technical solutions provided by the embodiments of the present invention have been introduced in detail above. Specific examples are used in this article to elaborate on the principles and implementation manners of the embodiments of the present invention. The descriptions of the above embodiments are only applicable to help understand the principles of the embodiments of the present invention; at the same time, for those of ordinary skill in the art, according to the embodiments of the present invention, there will be changes in the specific implementation manners and application scopes. In summary, the content of this specification should not be construed as a limitation to the present invention.
