Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of elevator traction unit assembly, and specifically to a traction machine with a stable support device and its usage method. Background Art
[0002] The traction machine, also known as the elevator main machine, is the power equipment of the elevator, which is composed of a motor, a brake, a coupling, a speed reducer, a traction wheel, etc. The function of the traction machine is to transmit and transfer power to make the elevator operate. The existing assembly method of the traction machine is to directly install the traction machine base at the top beam position of the car. The top beam is composed of two separate I-beams. Then, the installation positioning points on both sides of the traction machine base are directly fastened to the corresponding positioning holes of the I-beam. In actual use, due to the opening of holes at the top of the I-beam, the overall bearing capacity will be weakened to a certain extent, and then the weight of the traction machine cannot be too large. Moreover, since the position of the traction machine is determined after the holes are opened at the top of the I-beam, the position of the subsequent traction machine cannot be adjusted, which is not conducive to the elevator assembly operation; in addition, when assembling the existing top beam, it is necessary to place the beam on the top plane of the building and then cover the machine room at the position where the traction machine is placed. For some buildings with a flat roof structure, this elevator erection method is not applicable. Therefore, it is urgent to develop a traction machine installation structure with a stable support structure and that can eliminate the need for an additional machine room cover. Summary of the Invention
[0003] In view of the above problems, the present invention provides a traction machine with a stable support device, which ensures the stable and reliable installation of the traction machine, enables the position of the traction machine to be finely adjusted according to the actual position, and moreover, enables the top of the building to have no additional machine room, making the roof of the building have more expandability.
[0004] A traction machine with a stable support device, characterized in that it comprises:
[0005] A car inner cavity, which includes two side walls, and installation concave cavities are preset at the top positions of the two side walls;
[0006] A top beam assembly, which is formed by combining two beams, positioning baffles at both ends, and positioning angle steels at both ends. The positioning baffle includes an upper fixing plate and a vertical baffle. The positioning angle steel includes a first surface welded to the beam and a second surface for fixing to the side wall. The two beams with the same length are arranged at intervals in the width direction and are connected into a whole through the upper fixing plate of the positioning baffle. After the two beams are combined into one through the positioning baffles at both ends, the first surfaces of the corresponding positioning angle steels are welded to the two sides at both ends in the length direction of the two beams. The two ends in the length direction of the two beams respectively protrude from the second surface of the positioning angle steel to form side convex support ends;
[0007] A traction machine, which includes a traction machine base and a traction machine body;
[0008] and a traction machine mounting support plate, on both sides in the width direction of which there are respectively arranged traction machine positioning hole groups;
[0009] The traction machine mounting support plate is welded at the installation position corresponding to the traction machine of the top crossbeam assembly. Both sides of the traction machine mounting support plate protrude from both sides in the width direction of the top crossbeam assembly. The traction machine base is fixedly connected to the corresponding positioning holes of the corresponding traction machine positioning hole groups through traction machine connecting bolts;
[0010] The height and width of the installation concave cavity are greater than the size of the top crossbeam assembly after combining two crossbeams. The side convex support ends of the top crossbeam assembly respectively extend into the installation concave cavity. A shock absorption pad assembly is arranged between the bottom of the side convex support end and the bottom surface of the installation concave cavity. After being assembled in place, the outer surface of the vertical baffle of the positioning baffle is closely attached to the side wall.
[0011] Its further feature is that:
[0012] Both of the two crossbeams are C-shaped steel. The two C-shaped steels are arranged facing each other, so that the assembly of the traction machine connecting screws will not be interfered by the upper plane of the crossbeam;
[0013] It further includes a counterweight rope head plate. The counterweight rope head plate is positioned at the position directly below the traction machine of the two C-shaped steels through connecting bolts. A plurality of rope head mounting parts are fixedly arranged in the central area of the counterweight rope head plate. The height of the upward protrusion of the rope head mounting parts is lower than the height of the C-shaped steel. Avoidance notch grooves are opened in the areas of the bottom plates of the two C-shaped steels corresponding to the rope head mounting parts. The rope head mounting parts are arranged in the areas of the avoidance notch grooves. The thickness of the counterweight rope head plate is greater than the thickness of the bottom plate of the C-shaped steel, ensuring that at the position where the avoidance notch groove is opened, the bearing capacity of the entire top crossbeam will not only not decrease, but will be reliably improved;
[0014] Connecting positioning holes are arranged at the positions of the C-shaped steel corresponding to the positioning connection holes of the counterweight rope head plate. The connecting positioning holes and the positioning connection holes are reliably connected through bolts and threads. The area of the counterweight rope head plate covers the corresponding area of the connecting positioning holes. And because the thickness of the counterweight rope head plate is greater than the thickness of the bottom plate of the C-shaped steel, ensuring that at the position where the connecting positioning hole is opened, the bearing capacity of the entire top crossbeam will not only not decrease, but will be reliably improved;
[0015] The counterweight rope head plate is arranged below the top crossbeam assembly, which shortens the length of the corresponding rope and reduces the cost;
[0016] Waist-shaped holes are respectively arranged at the bottom plate positions at both ends of the two groups of C-shaped plates in the length direction. The upper fixed plate of the positioning baffle is connected to the waist-shaped holes through fasteners, which enables the position of the vertical baffle to be reliably adjusted according to the site, ensuring the reliable installation of the top crossbeam assembly.
[0017] The shock pad assembly includes an upper plate, an intermediate shock layer group, and a lower plate. The thickness of the intermediate shock layer group is set according to requirements, and the thickness of both ends of the intermediate shock layer group is differentially set according to whether the top crossbeam assembly is horizontal, ensuring the horizontal arrangement of the traction machine.
[0018] An installation method of a traction machine with a stable support device is characterized in that it includes the following steps:
[0019] S1. Hoist two groups of crossbeams into the car respectively in advance, and then adjust the positions of the crossbeams so that the side convex support ends of the crossbeams respectively extend into the corresponding installation concave cavities on both side walls.
[0020] S2. Pre-install positioning baffles at both ends of the two crossbeams in the length direction, so that the upper fixed plate of the installation baffle is connected to the corresponding connection positions of the two side crossbeams through fasteners, but no fastening operation is performed.
[0021] S3. Arrange the shock pad assemblies respectively directly below the two side convex support ends of the top crossbeam assembly, so that the top crossbeam assembly is supported on the bottom surface of the installation concave cavity.
[0022] S4. Detect the levelness of the upper surface of the top crossbeam assembly with a spirit level, and complete the levelness adjustment of the top crossbeam assembly by adjusting the thickness of the shock pad assemblies on both sides.
[0023] S5. Set the vertical baffle of the positioning baffle close to the side wall, and then fasten the upper fixed plate of the installation baffle and the corresponding connection position of the crossbeam.
[0024] S6. Then, the positioning holes on the second surface of the positioning angle steel are reliably positioned through expansion bolts, and the first surface of the positioning angle steel is welded to the outside of the length end of the corresponding crossbeam, so that the top crossbeam assembly is reliably positioned at the top of the car.
[0025] S7. Obtain the corresponding position of the traction machine through measurement and correction, then weld the traction machine installation support plate to the corresponding position of the top crossbeam assembly, and then fix the traction machine base of the traction machine on the traction machine installation support plate through the traction machine connection bolts to complete the stable support installation of the traction machine.
[0026] After adopting the structure of the present invention, an installation concave cavity is pre-opened on one opposite side wall of the building car. Then, two groups of cross beams are respectively inserted into the car, and the side convex supporting ends are made to penetrate deep into the installation concave cavity. Then, through the installation of the positioning baffle, the placement of the shock-absorbing pad, and the installation of the positioning angle steel, the top cross beam assembly is horizontally and stably supported in the preset installation concave cavity in the car. At this time, after precise measurement, the traction machine installation support plate is accurately welded in the middle area of the upper surface of the top cross beam assembly. Then, the traction machine base of the traction machine is fixedly installed on the traction machine installation support plate through the traction machine connecting bolts, completing the stable support installation of the traction machine. The supporting part of the cross beam for supporting the traction machine does not require hole opening operation, and according to the position of the traction machine on site, the position of the traction machine installation support plate can be adjusted in time to ensure that the installation dimensions of the traction machine after assembly meet the requirements of stable and reliable operation; and during the actual installation process, it is designed that the top of the traction machine after installation is not higher than the upper surface of the building, which enables the top of the building to not require an additional machine room, making the roof of the building have more expandability.

Detailed implementation mode
[0035] A traction machine with a stable support device, see Figures 1-6 , which includes a car inner cavity 10, a top beam assembly 20, a traction machine 30, and a traction machine installation support plate 40;
[0036] The car inner cavity 10 includes two side walls 11, and installation concave cavities 12 are preset at the top positions of the two side walls 11;
[0037] The top beam assembly 20 is formed by combining two groups of beams 50, positioning baffles 60 at both ends, and positioning angle steels 70 at both ends. The positioning baffle 60 includes an upper fixing plate 61 and a vertical baffle 62. The positioning angle steel 70 includes a first surface 71 welded to the beam 50 and a second surface 72 for fixing to the side wall 11. The two groups of beams 50 with the same length are arranged at intervals in the width direction and are connected into an integral body through the upper fixing plate 61 of the positioning baffle 60. After the two groups of beams are combined into an integral body through the positioning baffles 60 at both ends, the first surfaces 71 of the corresponding positioning angle steels 70 are welded to both sides of both ends in the length direction. The two ends of the two groups of beams 50 protrude laterally from the second surface 72 of the positioning angle steel 70 to form a laterally protruding support end 51. The positioning holes on the second surface 72 of the positioning angle steel 70 are reliably positioned on the side wall 11 through expansion bolts 130;
[0038] The traction machine 30 includes a traction machine base 31 and a traction machine body 32;
[0039] Traction machine positioning hole groups 41 are respectively arranged at both positions in the width direction of the traction machine installation support plate 40, and each group of traction machine positioning hole groups 41 is arranged in sequence along the length direction, ensuring reasonable and reliable fastening according to the actual position of the traction machine during actual assembly;
[0040] A traction machine installation support plate 40 is welded at the installation position of the traction machine 30 corresponding to the top beam assembly 20. The two sides of the traction machine installation support plate 40 protrude laterally from both sides in the width direction of the top beam assembly 20. The traction machine base 31 is fixedly connected to the corresponding positioning holes of the corresponding traction machine positioning hole groups 41 through traction machine connecting bolts 80;
[0041] The height and width of the installation concave cavity 12 are greater than the size of the top beam assembly 20 combined by the two groups of beams 50. The laterally protruding support ends 51 of the top beam assembly 20 respectively extend into the installation concave cavity 12. A shock pad assembly 90 is arranged between the bottom of the laterally protruding support end 51 and the bottom surface of the installation concave cavity 12. After being assembled in place, the outer surface of the vertical baffle 62 of the positioning baffle 60 is closely attached to the side wall 11, ensuring the stable and reliable assembly of the top beam assembly 20.
[0042] In a specific embodiment, both groups of cross beams 50 are C-shaped steels, and the two groups of C-shaped steels are arranged facing each other, so that the assembly of the traction machine connection bolts 80 will not be interfered by the upper plane of the cross beam 50.
[0043] During specific implementation, it further includes a counterweight rope head plate 100. The counterweight rope head plate 100 is positioned at a position directly below the two groups of C-shaped steels corresponding to the traction machine 30 through connection bolts 120. A number of rope head mounting parts 110 are fixedly arranged in the central area of the counterweight rope head plate 100. The protruding height of the rope head mounting parts 110 is lower than the height of the C-shaped steel. Avoidance notch grooves 52 are formed in the bottom plates of the two groups of C-shaped steels corresponding to the areas of the rope head mounting parts 110. The rope head mounting parts 110 are arranged in the areas of the avoidance notch grooves 52. The thickness of the counterweight rope head plate 100 is greater than the thickness of the bottom plate of the C-shaped steel, ensuring that at the position where the avoidance notch grooves 52 are formed, the bearing capacity of the entire top cross beam assembly 20 will not only not decrease, but will be reliably improved. In a specific embodiment, the number of the rope head mounting parts 110 is 8 groups, and 5, 6, 7, or 8 corresponding steel wires can be placed according to needs.
[0044] During specific implementation, connection positioning holes 53 are arranged at the positions of the C-shaped steel corresponding to the positioning connection holes of the counterweight rope head plate 100. The connection positioning holes 53 and the positioning connection holes are reliably connected through bolts and threads. The surface area of the counterweight rope head plate 100 covers the corresponding area of the connection positioning holes 53. And because the thickness of the counterweight rope head plate 53 is greater than the thickness of the bottom plate of the C-shaped steel, ensuring that at the position where the connection positioning holes 53 are formed, the bearing capacity of the entire top cross beam assembly 20 will not only not decrease, but will be reliably improved.
[0045] The counterweight rope head plate 100 is arranged below the top cross beam assembly 20, which reduces the length of the corresponding steel wire ropes and lowers the cost.
[0046] In a specific embodiment, waist-shaped holes 54 are respectively arranged at the bottom plate positions at both ends in the length direction of the two groups of C-shaped plates. The upper fixing plate 61 of the positioning baffle 60 is connected to the waist-shaped holes 54 through fasteners, which enables the position of the vertical baffle 62 to be reliably adjusted according to the site, ensuring the reliable installation of the top cross beam assembly 20.
[0047] In a specific embodiment, the shock absorption pad assembly 90 also has the function of adjusting the horizontal error. The shock absorption pad assembly 90 includes an upper plate 91, an intermediate shock absorption layer group 92, and a lower plate 93. The thickness of the intermediate shock absorption layer group 92 is set according to requirements, and the intermediate shock absorption layer group 92 is set with different thicknesses at both ends according to whether the top cross beam assembly 20 is horizontal, ensuring the horizontal arrangement of the traction machine 30.
[0048] An installation method of a traction machine with a stable support device includes the following steps:
[0049] S1. Pre-lift two groups of crossbeams into the car respectively, and then adjust the positions of the crossbeams so that the side convex supporting ends of the crossbeams extend into the corresponding installation concave cavities on both sides of the side walls respectively;

[0051] S3. Arrange the shock pad assemblies respectively directly below the side convex supporting ends of the top crossbeam assembly, so that the top crossbeam assembly is supported on the bottom surface of the installation concave cavity;
[0052] S4. Detect the levelness of the upper surface of the top crossbeam assembly with a spirit level, and complete the levelness adjustment of the top crossbeam assembly by adjusting the thickness of the shock pad assemblies on both sides;
[0053] S5. Set the vertical baffles of the positioning baffles closely against the side walls, and then fasten the upper fixed plates of the installation baffles and the corresponding connection positions of the crossbeams;
[0054] S6. Then reliably position the positioning holes on the second surface of the positioning angle steel through expansion bolts, and weld the first surface of the positioning angle steel to the outside of the length end of the corresponding crossbeam, so that the top crossbeam assembly is reliably positioned at the top of the car;
[0055] S7. Obtain the corresponding position of the traction machine through measurement and correction, then weld the traction machine installation support plate to the corresponding position of the top crossbeam assembly, and then fixedly install the traction machine base of the traction machine on the traction machine installation support plate through traction machine connection bolts to complete the stable support installation of the traction machine;

[0057] The principle is as follows: First, install concave cavities on the opposite side walls of the building car. Then, insert two sets of crossbeams into the car respectively, and make the side convex supporting ends extend into the installation concave cavities. Next, through the installation of positioning baffles, the placement of shock pads, and the installation of positioning angle steels, the top crossbeam assembly is horizontally and stably supported in the preset installation concave cavity in the car. At this time, after precise measurement, the traction machine installation support plate is accurately welded to the middle area of the upper surface of the top crossbeam assembly. Then, the traction machine base of the traction machine is fixedly installed on the traction machine installation support plate through traction machine connection bolts, completing the stable support installation of the traction machine. The supporting part of the crossbeam for supporting the traction machine does not require hole operation, and according to the position of the traction machine on site, the position of the traction machine installation support plate can be adjusted in time to ensure that the installation dimensions of the traction machine after assembly meet the requirements of stable and reliable operation. Moreover, in the actual installation process, it is designed that the top of the traction machine does not exceed the upper surface of the building after installation, which enables the building top to have more expandability without the need to set up an additional machine room on the top of the building.
