Description

Technical Field

[0001] The present invention relates to the technical field of traction machines, 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 the brake need to be equipped with corresponding junction boxes respectively.

[0003] In order to achieve the function more economically and ensure safety in the limited space of the machine room or shaft, the elevator structure is often relatively compact, which may affect the convenience of its installation, maintenance and operation. For example, the design of the junction box structure and installation position of the traction machine is often limited by the space of the machine room or shaft components, that is, the inspection port of the junction box must face the front or back of the traction machine to facilitate the operator to connect the cables.

[0048] In order to facilitate the 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 merely used to distinguish names and does not represent a specific quantity or order.

[0050] Unless specifically stated 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 a component is considered to be "fixed to" another component, it can be directly fixed to the other component or there can be a central component; when an component is considered to be "connected to" another component, it can be directly connected to the other component or there can be a central component at the same time; when an component is considered to be "installed on" another component, it can be directly installed on the other component or there can be a central component at the same time. When an component is considered to be "set on" another component, it can be directly set on the other component or there can be a central component at the same time.

[0052] The present invention proposes an integrated traction machine 100, such as Figures 1 to 6As shown, the machine base 1 includes a machine base 1 and a traction wheel 2. The machine base 1 includes a first support body 11 and a second support body 12. The first support body 11 is installed on the second support body 12. The second support body 12 has a support shaft 121. The traction wheel 2 is rotatably installed on the support shaft 121. The first support body 11 is at least partially bent and 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 groove 32 is formed in the first terminal box 3. The first terminal box 3 has a first outlet hole 33 and a first inlet hole 34. The first inlet hole 34, the first wire groove 32, and the first outlet hole 33 are connected in sequence. The first wire groove 32 has a first opening 301. The first opening 301 is arranged opposite to the first inlet hole 34. The opening directions of the first inlet hole 34 and the first opening 301 are consistent with the axis center line direction of the support shaft 121. The opening direction of the first outlet hole 33 intersects with the axis center line 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-casted, and the first support body 11 is bent to form the first junction box 3. The first junction box 3 is arranged above the second support body 12. The first wire groove 32 of the first junction box 3 is used to accommodate cables. The first end of the cable passes through the first wire inlet hole 34 and is connected to the stator. The second end of the cable is installed on the first wiring terminal 39 of the first wire groove 32 and passes through the first wire outlet hole 33 to connect to the external power supply. Since the first junction box 3 is not installed close to the side wall of the traction machine 100, when the opening direction of the first wire outlet hole 33 intersects with the axial centerline direction of the support shaft 121, when the cable extends from the first wire outlet hole 33 to connect to the external power supply, the cable will not contact the inner wall of the elevator shaft, 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 installed 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 arranged 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 below the position of the first opening 301. When the traction wheel 2 rotates, the traction rope is used to pull the car. The position above the traction wheel 2 is generally spacious, and the first opening 301 is far away from the wall, so 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, 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 use of the cable. Specifically, there is a stator outlet hole 36 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 arranged 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, and the pressure plate 38 is detachably installed 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, and the cable from the stator to the second opening 302 can be straightened at the second opening 302 to avoid the cable from being folded 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, and at the first wire slot 32, the cable in the wiring channel 35 can be straightened to avoid the cable from being folded back or compressed in the wiring channel 35; 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 folded back or compressed, thereby avoiding cable waste and cable breakage or short circuit after long-term compression. When the cable arrangement of the first junction box 3 is completed, the second opening 302 can be sealed with a pressure plate 38 to prevent the cable from being affected by the external environment and improve the conductive safety of the cable.

[0057] In some embodiments, Figure 6 As shown, due to the coordination between the stator and the rotor, after the stator conducts electricity, the rotor rotates relative to the stator and drives the traction wheel 2 to rotate; in order to prevent the traction wheel 2 from interfering with the cable during rotation, or from contacting or rubbing with the cable during rotation. Specifically, the first junction box 3 also has a partition 37 and a first sealing plate 31, the first sealing plate 31 is installed at the first opening 301, the partition 37 is installed in the first support body 11, and a stator outlet hole 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 arranging the partition 37 in the first support body 11, and forming the stator outlet hole 36 between the partition 37 and the second support body 12, when the cable is fixed to the stator, it is led out from the stator outlet hole 36, and the partition 37 isolates the cable outside the stator outlet hole 36, and one side of the partition 37 is the rotor, so as to prevent the rotor from contacting the cable during rotation. Moreover, a linear wiring channel 35 is formed between the partition plate 37 and the pressure plate 38 . The cables are guided into the linear wiring channel 35 after passing through the stator outlet hole 36 , and then reach the first wire slot 32 after being bent.

[0058] In some embodiments, since the brake and the 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 terminals 39, and the second junction box 4 is used to install brake cables and second terminals. 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, so as 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. 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 consistent with the axial centerline direction of the support shaft 121. The second junction box 4 configured in this way can also avoid the extrusion of cables during wiring, and reserve sufficient space for cables to pass through the second wire outlet hole 43, and reserve sufficient space for maintenance personnel to maintain the electronic components in the second junction box 4.

[0060] Moreover, a first lifting 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, a second avoidance groove 102 is provided between the second end of the connecting component 10 and the second junction box 4, and the first avoidance groove 101 and the second avoidance groove 102 are arranged on both sides of the first lifting hole 105. Specifically, the first hoisting hole 105 is provided on the connection component 10, 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, and the first hoisting hole 105 has a first avoidance groove 101 and a second avoidance groove 102 on both sides, so that when the first hoisting hole 105 is installed with a hook, the connection component 10 has enough space to avoid the hook or the hoisting rope, so as to avoid the hoisting rope or the hook from being squeezed with the traction machine 100 during the hoisting process, and the hoisting rope and the hook are in a taut state during transportation, so as to avoid the hoisting rope and the hook from causing wear to the outer surface of the traction machine 100 during transportation, and also improve the stability of the hook and the connection component 10 after being fixed. Moreover, the first support body 11 and the second support body 12 are an integrated structure, and the second support body 12 is hoisted and transported along with the first support 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 hoisted, and after the traction machine 100 leaves the ground, the traction machine 100 is always in a balanced state, and its posture remains unchanged, so that after the traction machine 100 is transported to the preset position, the traction machine 100 can be grounded and assembled without adjusting the posture of the traction machine 100, further optimizing the operating 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 connection assembly 10 is T-shaped. Such a connection assembly 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 compactness of the structure of the first support body 11 and improve the stability of the base 1. Specifically, Figure 3 and Figure 4As shown, the connection component 10 includes a first connection plate 111 and a second connection plate 112, the first connection plate 111 is installed on the second support body 12, the first end of the first connection plate 111 is fixed to the first end of the first junction box 3, the second end of the first connection plate 111 is fixed to the first end of the second junction box 4, the second connection plate 112 is installed in the middle section of the first connection plate 111, and the second connection plate 112 is also fixed to the second support body 12; a first avoidance groove 101 is formed between the first side wall of the second connection plate 112, the inner side of the first connection 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 connection plate 112, the inner side of the first connection plate 111, and the outer side of the second junction box 4; a first hanging hole 105 is opened on the second connection plate 112, and passes through the second side wall from the first side wall of the second connection plate 112.

[0064] The first junction box 3 and the second junction box 4 are fixed by the first connecting plate 111, and 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 support body 12. The first connecting plate 111 is fixed to the second support body 12, so that the connection area between the connecting component 10 and the second support body 12 can be increased. At the same time, the connecting component 10 is also fixed to the first junction box 3 and the second junction box 4, so that the integrity of the structure between the first support body 11 and the second support body 12 can be improved, and the stability of the base 1 can be improved. By setting the installation position of the first connecting plate 111 and the second connecting plate 112, the first lifting hole 105 and two avoidance grooves are opened on the first support body 11, and any structure on the first support body 11 has a corresponding role or function; such a layout setting also makes the first support body 11 more compact in structure.

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

[0066] In some embodiments, a single-point lifting is adopted, 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 a second lifting hole 106 is formed on the third connection plate 113; a third avoidance groove 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 the third avoidance groove 103 is arranged 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, the third connection plate 113 and the fourth connection plate 114 are arranged opposite to each other, and a third lifting hole 107 is formed on the fourth connection plate 114; a fourth avoidance groove 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 the fourth avoidance groove 104 is arranged on one side of the third lifting hole 107.

[0067] By setting the second lifting hole 106 on the third connecting plate 113 and the 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 that cooperate with three lifting ropes respectively. 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, when it is necessary to lift a traction machine 100 having 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 forces between the multiple lifting points are 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 traction 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 tensions at the three connection positions are consistent, and the tensions on the three pull ropes are also equal, avoiding the risk of rope breakage.

[0069] like Figure 1 and Figure 2As shown, when the hoisting and transporting traction machine 100, three hoisting ropes are respectively installed on the first hoisting hole 105, the second hoisting hole 106 and the third hoisting hole 107 through three hooks, and the three hoisting 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 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 supporting body 12, and the fifth avoidance groove 108 is extended along the circumferential direction of the second supporting 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, the first terminal box 3 is aligned with the second terminal box 4, so that after the first supporting body 11 is die-cast, the first terminal box 3 and the second terminal box 4 are symmetrically arranged, and the traction machine 100 can also be an overall symmetrical structure, thereby improving the stability of its structure.
