Description

Technical Field

[0001] The present invention relates to the technical field of traction machines, and in particular to an integrated traction machine. Background Art

[0002] Permanent magnet synchronous traction machine, also known as gearboxless transmission, is used to be installed in the elevator machine room or elevator shaft, generally on the top floor of the building or inside the shaft. It is the power device of the elevator and its structure often includes two major components: the motor and the brake. The motor and brake each require a corresponding junction box.

[0003] To achieve functionality and ensure safety more economically within the limited space of a machine room or hoistway, elevators are often built in a relatively compact structure, which can compromise installation, maintenance, and operational convenience. For example, the design and installation location of a motor's junction box are often limited by the space available in the machine room or hoistway. This means the junction box's access opening must face the front or back of the motor to facilitate cable connections.

[0004] If the junction box is installed on the side of the traction machine, the disadvantages are: the stator cables are easily squeezed and abraded; and when the traction machine needs to connect cables during installation and maintenance, due to space limitations in the machine room or hoistway structure, operators often have to lean sideways to connect the cables, or even be unable to do so. Therefore, the existing location of the junction box on the machine base greatly tests the technician's experience and expertise. Summary of the Invention

[0048] To facilitate understanding of the present invention, specific embodiments of the present invention will be described in more detail below with reference to the accompanying drawings.

[0049] Unless otherwise specified or defined, the "first, second..." used in this article is only used to distinguish names and does not represent a specific quantity or order.

[0050] Unless stated otherwise or defined otherwise, the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0051] It should be noted that when an element is considered to be "fixed to" another element, it can be directly fixed to the other element or there can be an intermediate element; when an element is considered to be "connected to" another element, it can be directly connected to the other element or there can be an intermediate element; when an element is considered to be "mounted on" another element, it can be directly mounted on the other element or there can be an intermediate element. When an element is considered to be "located on" another element, it can be directly located on the other element or there can be an intermediate element.

[0052] The present invention proposes an integrated traction machine 100, such as Figures 1 to 6As shown, it includes a machine base 1 and a traction sheave 2. The machine base 1 includes a first support body 11 and a second support body 12. The first support body 11 is mounted on the second support body 12. The second support body 12 has a support shaft 121. The traction sheave 2 is rotatably mounted on the support shaft 121. The first support body 11 is at least partially bent to form at least one first terminal box 3. The first terminal box 3 is arranged above the second support body 12. A first wire duct 32 is formed in the first terminal box 3. The first terminal box 3 has a first wire outlet hole 33 and a first wire inlet hole 34. The first wire inlet hole 34, the first wire duct 32, and the first wire outlet hole 33 are connected in sequence. The first wire duct 32 has a first opening 301. The first opening 301 is arranged opposite to the first wire inlet hole 34. The opening directions of the first wire inlet hole 34 and the first opening 301 are consistent with the axis direction of the support shaft 121. The opening direction of the first wire outlet hole 33 intersects with the axis direction of the support shaft 121.

[0053] Specifically, during the production process, the first support body 11 and the second support body 12 are integrally die-cast. The first support body 11 is bent to form a first terminal box 3, which is positioned above the second support body 12. The first wire duct 32 of the first terminal box 3 is used to accommodate cables. The first end of the cable passes through the first wire inlet 34 and connects to the stator. The second end of the cable is mounted on the first terminal 39 of the first wire duct 32 and passes through the first wire outlet 33 to connect to an external power source. Because the first terminal box 3 is not mounted near the side wall of the traction machine 100, when the opening direction of the first wire outlet 33 intersects the axis of the support shaft 121, the cable does not contact the inner wall of the elevator shaft when it extends from the first wire outlet 33 to connect to the external power source, thereby preventing the cable from being squeezed by the inner wall of the elevator shaft.

[0054] Moreover, the first junction box 3 also has a first sealing cover 31, which is detachably mounted at the first opening 301. The first opening 301 is the inspection port of the first junction box 3, and the first opening 301 is opposite to the first wire entry hole 34. When maintenance is needed, the first sealing cover 31 is removed, and the maintenance wire is installed on the first terminal 39 through the first opening 301. Since the opening direction of the first opening 301 is consistent with the axial centerline direction of the support shaft 121, the traction wheel 2 is located below the first opening 301. When the traction wheel 2 rotates, the car is pulled by the traction rope. The position above the traction wheel 2 is generally spacious, and the first opening 301 is far away from the wall. There is enough space for maintenance personnel to connect the first terminal 39 at the first opening 301 or maintain the electronic components in the first wire trough 32.

[0055] In some embodiments, as Figure 1 、 Figure 2 、 Figure 6As shown, since both ends of the cable need to be installed on the stator and the first terminal 39, in order to avoid the risk of repeated bending and compression of the cable in the base 1 and to save the amount of cable used, specifically, a stator outlet hole 36 is provided between the first support body 11 and the second support body 12. The first support body 11 has a wiring channel 35, a second opening 302, and a pressure plate 38. The wiring channel 35 is at least partially bent. The second opening 302 is provided on one side of the wiring channel 35 and is connected to the wiring channel 35. The stator outlet hole 36, the wiring channel 35, and the first inlet hole 34 are connected in sequence. The pressure plate 38 is detachably mounted at the second opening 302.

[0056] It can be understood that after the first end of the cable is connected to the stator, the second end of the cable passes through the second opening 302. At the second opening 302, the cable from the stator to the second opening 302 can be straightened to avoid the cable from being bent back or compressed. Then, at the second opening 302, the second end of the cable passes through the wiring channel 35 and enters the first wire slot 32 from the first wire entry hole 34. At the first wire slot 32, the cable in the wiring channel 35 can be straightened to avoid the cable from being bent back or compressed. Therefore, the cable between the first wire slot 32 and the stator can be operated at the second opening 302 to avoid the cable from being bent back or compressed. This avoids cable waste and prevents the cable from breaking or short-circuiting after being compressed for a long time. When the cable arrangement of the first junction box 3 is completed, the pressure plate 38 can be used to seal the second opening 302 to prevent the cable from being affected by the external environment and improve the conductive safety of the cable.

[0057] In some embodiments, as Figure 6 As shown, due to the coordination between the stator and the rotor, after the stator becomes conductive, the rotor rotates relative to the stator and drives the traction sheave 2 to rotate. To prevent the traction sheave 2 from interfering with the cables during rotation, or from contacting or rubbing against the cables during rotation, the first junction box 3 further comprises a partition 37 and a first sealing plate 31. The first sealing plate 31 is mounted at the first opening 301, and the partition 37 is mounted within the first support body 11. A stator cable outlet 36 is formed between the partition 37 and the second support body 12. A linear wiring channel 35 is formed between the partition 37 and the pressure plate 38. By disposing the partition 37 within the first support body 11 and forming the stator cable outlet 36 between the partition 37 and the second support body 12, when the cables are fixed to the stator, they are led out of the stator cable outlet 36. The partition 37 isolates the cables outside the stator cable outlet 36. One side of the partition 37 is the rotor, thus preventing the rotor from contacting the cables during rotation. Moreover, a linear wiring channel 35 is formed between the partition plate 37 and the pressure plate 38 . The cables pass through the stator outlet hole 36 and are guided into the linear wiring channel 35 . Then, they are bent and reach the first wire slot 32 .

[0058] In some embodiments, since the brake and motor in the traction machine 100 need to operate independently, the traction machine 100 needs to be equipped with two relatively independent junction boxes. In addition, the traction machine 100 is heavy and needs to be transported by hoisting. The setting of the hoisting holes on the traction machine 100 also greatly tests the professional ability of the technicians. Specifically, Figure 1 and Figure 2 As shown, the first support body 11 is bent to form the first junction box 3 and the second junction box 4; the first support body 11 also includes a connecting component 10, and the first junction box 3 is connected to the second junction box 4 through the connecting component 10; the first junction box 3 is used to install electronic cables and first terminal blocks 39, and the second junction box 4 is used to install brake cables and second terminal blocks. The first junction box 3 is fixed to the second junction box 4 through the connecting component 10, and the first junction box 3 and the second junction box 4 are relatively independently arranged to facilitate the independent operation of the brake and the motor.

[0059] Preferably, Figures 1 to 4 As shown, the second junction box 4 has a second sealing cover 41, a second wire trough 42, a second wire outlet hole 43, and a second wire inlet hole 44. The second wire trough 42 also has an inspection port, and the second sealing cover 41 is installed at the inspection port. The opening directions of the second wire outlet hole 43 and the second wire inlet hole 44 intersect, and the second wire inlet hole 44 is aligned with the axis of the support shaft 121. This configuration of the second junction box 4 can also prevent cable compression during wiring, leaving sufficient space for cables to pass through the second wire outlet hole 43, and sufficient space for maintenance personnel to facilitate maintenance of electronic components within the second junction box 4.

[0060] Moreover, a first hanging hole 105 is opened on the connecting component 10, a first avoidance groove 101 is provided between the first end of the connecting component 10 and the first junction box 3, and a second avoidance groove 102 is provided between the second end of the connecting component 10 and the second junction box 4. The first avoidance groove 101 and the second avoidance groove 102 are arranged on both sides of the first hanging hole 105. Specifically, a first hoisting hole 105 is provided on the connecting assembly 10, and the first terminal box 3 and the second terminal box 4 are symmetrically arranged relative to the first hoisting hole 105. The first hoisting hole 105 is used to hang a hook or a hoisting rope. The first hoisting hole 105 has a first avoidance groove 101 and a second avoidance groove 102 on both sides. In this way, when the hook is installed in the first hoisting hole 105, the connecting assembly 10 has sufficient space to avoid the hook or the hoisting rope, thereby preventing the hoisting rope or the hook from being squeezed against the traction machine 100 during the hoisting process. The hoisting rope and the hook are in a taut state during transportation, thereby preventing the hoisting rope and the hook from causing wear on the outer surface of the traction machine 100 during transportation, and also improving the stability of the hook and the connecting assembly 10 after being fixed. Moreover, the first supporting body 11 and the second supporting body 12 are an integrated structure, and the second supporting body 12 is hoisted and transported along with the first supporting body 11.

[0061] Preferably, Figure 1 and Figure 2 As shown, the position of the first hoisting hole 105 is on the same plumb line as the center of gravity of the traction machine 100. During the hoisting process, the center of gravity of the traction machine 100 is lifted. After the traction machine 100 leaves the ground, the traction machine 100 is always in a balanced state and its posture remains unchanged. After the traction machine 100 is transported to the preset location, the traction machine 100 can be grounded and assembled without adjusting its posture, further optimizing the efficiency of the hoisting and transportation operation of the traction machine 100.

[0062] Preferably, Figure 3 and Figure 4 As shown, the cross section of the connecting component 10 is T-shaped. Such a connecting component 10 has a simple structure, is easy to manufacture, and also meets the design requirements of the avoidance groove.

[0063] In some embodiments, in order to improve the structural compactness of the first support body 11 and improve the stability of the base 1. Specifically, Figure 3 and Figure 4As shown, the connecting assembly 10 includes a first connecting plate 111 and a second connecting plate 112. The first connecting plate 111 is installed on the second supporting body 12. The first end of the first connecting plate 111 is fixed to the first end of the first junction box 3, and the second end of the first connecting plate 111 is fixed to the first end of the second junction box 4. The second connecting plate 112 is installed in the middle section of the first connecting plate 111, and the second connecting plate 112 is also fixed to the second supporting body 12; a first avoidance groove 101 is formed between the first side wall of the second connecting plate 112, the inner side of the first connecting plate 111, and the outer side of the first junction box 3; a second avoidance groove 102 is formed between the second side wall of the second connecting plate 112, the inner side of the first connecting plate 111, and the outer side of the second junction box 4; a first hanging hole 105 is opened on the second connecting plate 112, and passes through the first side wall of the second connecting plate 112 to the second side wall.

[0064] The first junction box 3 and the second junction box 4 are fixed together via a first connecting plate 111. The second connecting plate 112 is mounted in the middle of the first connecting plate 111. The second connecting plate 112 is also fixed to the second support body 12. The first connecting plate 111 is fixed to the second support body 12. This increases the connection area between the connecting assembly 10 and the second support body 12. At the same time, the connecting assembly 10 is also fixed to the first junction box 3 and the second junction box 4. This improves the structural integrity between the first support body 11 and the second support body 12, and thus improves the stability of the machine base 1. By setting the mounting positions of the first connecting plate 111 and the second connecting plate 112, a first lifting hole 105 and two avoidance grooves are provided on the first support body 11. Any structure on the first support body 11 has a corresponding role or function. This layout also makes the structural layout of the first support body 11 more compact.

[0065] Preferably, Figure 4 As shown, the first connecting plate 111 also has a supporting surface 115, which is used to abut or fix with the fixing bracket, so that after the base 1 is fixed, the fixing bracket supports or fixes the first connecting plate 111, thereby improving the stability of the top of the base 1.

[0066] In some embodiments, a single position is used for lifting, and this local position bears the entire deadweight of the traction machine 100, which may easily lead to the risk of partial breakage or deformation of the traction machine 100. In order to avoid single-point lifting and transportation, the lifting and transportation of the traction machine 100 is made more stable and safe. Specifically, Figures 3 to 5As shown, the connection assembly 10 further comprises a third connection plate 113, which is mounted on the second end of the first junction box 3 and has a second lifting hole 106 defined thereon. A third avoidance slot 103 is formed between one side of the third connection plate 113, the outer side of the first junction box 3, and the second support body 12, and is disposed on one side of the second lifting hole 106. The connection assembly 10 further comprises a fourth connection plate 114, which is mounted on the second end of the second junction box 4, with the third connection plate 113 and the fourth connection plate 114 disposed opposite each other and having a third lifting hole 107 defined thereon. A fourth avoidance slot 104 is formed between one side of the fourth connection plate 114, the outer side of the second junction box 4, and the second support body 12, and is disposed on one side of the third lifting hole 107.

[0067] By setting a second lifting hole 106 on the third connecting plate 113 and a third lifting hole 107 on the fourth connecting plate 114, the third avoidance groove 103 is used to avoid the hook of the second lifting hole 106, and the fourth avoidance groove 104 is used to avoid the hook of the third lifting hole 107. When the hoisting machine 100 is lifted, the hoisting machine 100 has three lifting holes at different positions, which are respectively matched with three lifting ropes. The hoisting machine 100 has more lifting points, avoiding single-position lifting, which can improve the stability and safety of the hoisting machine 100 during lifting.

[0068] In some embodiments, if it is necessary to lift a traction machine 100 with multiple connection positions, the transportation safety of the traction machine 100 is not considered during the design stage of the lifting point position of the traction machine 100; when the traction machine 100 is completely off the ground, the lifting force between the multiple lifting points is unbalanced, which will cause the traction machine 100 to adjust its posture in the air due to its own weight. When the posture of the traction machine 100 is adjusted, a certain inertial force will be generated. This force plus the weight of the traction machine 100 may be greater than the lifting weight, or exceed the maximum stress of the lifting rope, and the lifting The rope may break, causing the hoisting machine 100 to fall in the air and causing a safety accident. In order to avoid the above-mentioned installation accidents, the second lifting hole 106 and the third lifting hole 107 are symmetrically arranged relative to the first lifting hole 105. In this way, when lifting, the lifting tension of the second lifting hole 106 and the third lifting hole 107 is equal, and the lifting tension of the second lifting hole 106 and the first lifting hole 105 is also equal. In this way, the lifting tension at the three connection positions is consistent, and the tension on the three pull ropes is also equal, avoiding the risk of rope breakage.

[0069] like Figure 1 and Figure 2As shown, when the hoisting and transporting the traction machine 100, three lifting ropes are respectively installed on the first lifting hole 105, the second lifting hole 106, and the third lifting hole 107 through three hooks. The three lifting ropes act on three different positions on the traction machine 100 respectively, so that the traction machine 100 can maintain a stable posture in the three stages before lifting, during lifting and transportation, and landing after lifting and transportation. There is no need to calibrate the posture of the traction machine during transportation, thereby improving the transportation efficiency and stability of the traction machine 100.

[0070] Preferably, Figures 1 to 5 As shown, the third connecting plate 113, the fourth connecting plate 114, and the first connecting plate 111 are arranged on the same plane; the first junction box 3 and the second junction box 4 are aligned, and the outer walls of the first junction box 3 and the second junction box 4 are both arranged on the same plane as the first connecting plate 111; a fifth avoidance groove 108 is formed between the outer wall of the first junction box 3 or the second junction box 4 and the second support body 12, and the fifth avoidance groove 108 extends along the circumference of the second support body 12; the fifth avoidance groove 108 and the third avoidance groove 103 are arranged on both sides of the second lifting hole 106; and / or, the fifth avoidance groove 108 and the fourth avoidance groove 104 are arranged on both sides of the third lifting hole 107. By arranging the third connecting plate 113, the fourth connecting plate 114, and the first connecting plate 111 on the same plane and aligning the first terminal box 3 with the second terminal box 4, the first terminal box 3 and the second terminal box 4 are symmetrically arranged after the die-casting of the first support body 11. This also provides an overall symmetrical structure for the traction machine 100, improving its structural stability. Furthermore, by providing the fifth avoidance slot 108, which avoids one side of the second and third lifting holes 106, 107, it facilitates the installation of hooks and lifting ropes in the second and third lifting holes 106, 107.

[0071] In some embodiments, as Figure 1 and Figure 4 As shown, the base 1 further has a boss 123. The second support body 12 is recessed inwardly to form a receiving groove 122. The boss 123 is mounted on the second support body 12 and located within the receiving groove 122. The support shaft 121 is mounted on the boss 123, and the traction sheave 2 is at least partially disposed within the receiving groove 122. Specifically, the circumference of the boss 123 is used to mount the stator, and the inner side of the traction sheave 2 is used to mount the rotor. When the traction sheave 2 is mounted on the support shaft 121 and rotatably connected to the support shaft 121 via a bearing, the stator and rotor are arranged relative to each other. When power is applied to the stator, the rotor is driven to rotate, thereby rotating the traction sheave 2.

[0072] It should be noted that in this traction machine 100, by positioning the first terminal box 3 above the second support body 12, the first cable outlet 33 intersects the axis of the support shaft 121, and the opening direction of the first opening 301 aligns with the axis of the support shaft 121. This prevents the cables in the first terminal box 3 from being squeezed when connected to an external power source. Furthermore, the first opening 301 provides ample space, making it easier for maintenance personnel to perform maintenance on the traction machine 100. Other traction machines 100 that utilize the installation position of the first terminal box 3 in the traction machine 100, as well as the positional relationship between the opening directions of the first cable outlet 33 and the first opening 301 and the support shaft 121, are all within the scope of protection of this application.
