Description

Technical Field

[0001] The present invention relates to the technical field of elevator equipment, and in particular to a driving structure of a heavy-load passenger and freight elevator. Background Art

[0002] An elevator is a permanent transportation device that serves several specific floors in a building. Its car runs on at least two rows of rigid tracks that are perpendicular to the horizontal plane or have an inclination angle of less than 15° to the plumb line. The main components of the elevator equipment are the traction drive system, car operation system, electric traction system, counterweight system, door system, safety system, guide system, control system, etc. Among them, the elevator traction drive system is the brain of the elevator equipment. Only by choosing a suitable elevator traction drive system can we ensure that the elevator can save time, effort, safety and smoothness in carrying people and goods up and down the building.

[0003] In the prior art, a Chinese patent document with publication number CN218841410U proposes an elevator drive structure in a machine room-less elevator drive structure, including a main engine beam, a main engine and a counterweight sheave seat are provided on the main engine beam, a traction wheel is provided on the main engine, a counterweight sheave seat is provided with a counterweight side fixed pulley and a counterweight side rope head, the counterweight side rope head is located between the counterweight side fixed pulley and the traction wheel, and also includes a first pair of return sheaves and a second pair of return sheaves, a traction rope is provided on the traction wheel, and the position distribution of the traction wheel, the counterweight side fixed pulley, and the counterweight side rope head cooperates with the first pair of return sheaves and the second pair of return sheaves to shorten the distance between the first pair of return sheaves and the second pair of return sheaves, thereby reducing the drive installation components and The width of the counterweight device itself takes up little space and is easy to install, thereby reducing the requirements for shaft space and construction costs and improving the effective space utilization of the shaft. However, the elevator traction machine will produce certain vibrations when pulling the steel rope during operation. Since the frequency of use of the elevator is very high, the vibration frequency of the traction machine is also high, and the vibration of the traction machine includes mixed vibrations in the vertical direction and the horizontal direction.

[0015] Beneficial effects of the present invention:

[0016] 1. This type of heavy-duty passenger and freight elevator drive structure installs a shock-absorbing assembly at the bottom of the traction machine. The vibration generated during the operation of the traction machine is transmitted to the mounting plate, which converts the vibration into swinging of the mounting plate. Part of the kinetic energy of the vibration is converted into the internal energy of friction between the clamp and the round roller.

[0017] 2. This type of heavy-duty passenger and freight elevator drive structure sets a cleaning component on the outside of the steel rope, utilizes the rotation of the return pulley and the transmission of the main pulley and the secondary pulley to drive the worm to rotate, and then drives the half gear to rotate, so that the return plate can perform linear reciprocating motion in the horizontal direction, so that a horizontal relative displacement occurs between the cleaning brush and the steel rope, thereby improving the cleaning effect of the cleaning brush and ensuring the cleanliness of the outer surface of the steel rope.

[0018] 3. This type of heavy-duty passenger and freight elevator drive structure has a lubrication component arranged on the upper part of the sheave beam, and the steel rope is clamped in the groove on the surface of the storage tube. During the movement of the steel rope, the storage tube is driven to rotate under the action of friction, and the lubricating oil on the surface of the ball will adhere to the outer surface of the steel rope, thereby lubricating the steel rope. At the same time, the long rod and the spiral plate are driven to rotate under the transmission of the transmission rod, gear one and gear two, stirring the lubricating oil and driving the lubricating oil to rise and fall through the cylinder, thereby ensuring that the lubricating oil is in a flowing state and maintaining the lubricating effect of the lubricating oil.

DETAILED DESCRIPTION

[0030] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to specific embodiments.

[0031] It should be noted that, unless otherwise defined, the technical or scientific terms used in the present invention should have the usual meanings understood by people with ordinary skills in the field to which the present invention belongs.

[0032] like Figures 1 to 8As shown, the driving structure of a large-load passenger and freight elevator includes a main beam 1 and a sheave beam 2. A shock-absorbing assembly is provided at the top of the main beam 1, and a traction machine 4 is provided on the upper part of the shock-absorbing assembly. A return pulley 5 is provided on the upper part of the main beam 1, and a cleaning assembly is provided on the side of the return pulley 5. Two return pulleys 7 are symmetrically distributed on the upper part of the sheave beam 2, and a lubrication assembly is provided between the two return pulleys 7. A steel rope 9 is provided on the outer surface of the traction wheel at the end of the traction machine 4, and a rope head assembly is provided at the end of the steel rope 9. The shock-absorbing assembly is a buffer structure between the traction machine 4 and the main beam 1, and the steel rope 9 is sequentially interspersed in the cleaning assembly and the lubrication assembly. The cleaning assembly is attached to the return pulley 5 for operation. The main beam 1 is provided with reinforcement ribs at the position where it is placed on the wall to increase the rigidity of the main beam. The elevator traction drive structure with a four-to-one traction ratio can maximize the utilization of the shaft space and save twice the electricity compared with the traditional two-to-one traction ratio drive structure, thereby saving energy and reducing consumption.

[0033] When the elevator is running, the rotation of the traction machine 4 drives the traction wheel at the driving end to rotate. The rotation of the traction wheel can drive the steel rope 9 to move, and then the car is pulled up and down after the redirection and positioning of the return rope pulley 2 7. The steel rope 9 synchronously pulls the counterweight block up and down under the redirection and positioning of the return rope pulley 1 5, playing a balancing role, so as to realize the lifting and lowering operation of the elevator. The specific components, connection methods and working methods of the motor drive structure are far from the existing technology well known to professionals in this field, and will not be elaborated on here. The traction machine 4 is installed on the shock-absorbing assembly, which can flexibly reduce and offset the vibration generated during the operation of the traction machine 4 to ensure the stability of the connection of the traction machine 4. The steel rope 9 will pass through the cleaning assembly and the lubrication assembly as the car rises and falls. The cleaning assembly can clean the dust and debris adhered to the steel wire 1002 rope to prevent dust and debris from being entangled on the sheave. The lubrication assembly can lubricate the steel rope 9 to ensure the smooth operation of the steel rope 9, reduce the friction between the steel rope 9 and the sheave, reduce the noise generated during operation, and improve the service life of the steel rope 9.

[0034] like Figure 2 and Figure 3As shown, the shock absorbing assembly includes a bottom plate 301 fixed to the top of the main beam 1, a support 302 is provided in the middle of the bottom plate 301, a round roller 303 is fixedly connected to the middle of the support 302, a clamp 305 is movably sleeved on the outer surface of the round roller 303, and a mounting plate 304 is fixedly connected to the top of the clamp 305. The traction machine 4 is provided on the upper surface of the mounting plate 304, and a baffle 306 is provided on the upper surface of the bottom plate 301. A slide groove 309 is provided at the partition of the baffle 306, and the inner part of the slide groove 309 is slidably connected to the Slider 308, the outer surface of which is hingedly connected to a support rod 307, the end of which, away from slider 308, is hingedly connected to the lower surface of mounting plate 304. A spring 310 is provided on one side of slider 308, and a rubber ring 313 is provided on the other side. Side plates 311 are fixedly connected to the lower portions of both sides of clamp 305. Pads 312 are provided on the upper surface of bottom plate 301. Two pads 312 are provided and symmetrically distributed on both sides of support 302. The lower surfaces of side plates 311 abut against the upper surfaces of pads 312.

[0035] The traction machine 4 is fixedly mounted on the upper part of the mounting plate 304 by means of bolts, nuts and other structures. The traction machine 4 generates vertical and horizontal vibrations during operation. Since the bottom of the mounting plate 304 is clamped to the outer surface of the round roller 303 by the clamp 305, the vibrations generated by the traction machine 4 will be transmitted and drive the mounting plate 304 to vibrate. Whether it is horizontal or vertical vibration, the mounting plate 304 will swing slightly around the round roller 303, converting part of the vibration kinetic energy into the internal energy of friction between the clamp 305 and the round roller 303. In addition, during the swinging process of the mounting plate 304, the side plate 311 will squeeze the pad 312 , which plays a role in limiting the swing amplitude. At the same time, the two ends of the mounting plate 304 will pull or push the support rod 307, thereby driving the slider 308 to slide in the slide groove 309, and then stretching or squeezing the spring 310. According to the principle that the action of force is mutual, the spring 310 will act on the support rod 307 to apply a reverse force to the mounting plate 304, and the slider 308 located at the raised end of the mounting plate 304 will squeeze the rubber ring 313, thereby reducing the elastic force of the spring 310, thereby playing an effect of flexibly reducing and balancing the swing. The use of flexible reduction can ensure the stability of the connection between the traction machine 4 and the mounting plate 304.

[0036] like Figure 4 and Figure 5As shown, the cleaning assembly includes a frame 601 fixed to the middle of the main beam 1, the end of the anti-ropes-5-axis rod is fixedly connected to the main pulley 602, the outer surface of the main pulley 602 is meshed with the secondary pulley 604 through the belt 603, the middle of the secondary pulley 604 is fixedly connected to the worm 605, the worm 605 is movably inserted into the interior of the frame 601, the inner wall of the frame 601 is movably connected to the worm wheel 606, the worm 605 is meshed with the worm wheel 606, and the middle of the side of the worm wheel 606 is fixedly connected to the half gear 607. The outer sleeve of the wheel 607 is provided with a return plate 608, and a rack 609 is provided inside the return plate 608 on the side close to the half gear 607. There are two racks 609 and they are distributed on the upper and lower sides of the return plate 608. The two racks 609 are staggered and meshed with the half gear 607. A cleaning brush 610 is provided in the middle of the return plate 608. A roller 612 is provided on the side of the return plate 608 away from the half gear 607. A track 611 is provided on the inner wall of the frame 601, and the roller 612 is movably arranged inside the track 611;

[0037] As the car rises and falls, the steel rope 9 passes through the cleaning assembly, comes into contact with the cleaning brush 610, and undergoes vertical relative displacement. The cleaning brush 610 can clean the dust and debris attached to the outer surface of the steel rope 9. At the same time, the return pulley 5 rotates under the traction of the steel rope 9, thereby driving the main pulley 602 located at the end of the shaft of the return pulley 5 to rotate, and pulls the secondary pulley 604 and the worm 605 to rotate synchronously through the belt 603. Since the wheel diameter ratio of the main pulley 602 and the secondary pulley 604 is two to one, the secondary pulley 604 rotates faster, and the worm 605 rotates faster. During the rotation process, the worm gear 606 and the half gear 607 are driven to rotate. Since the half gear 607 is placed inside the return plate 608, as the half gear 607 rotates, it will indirectly engage with the racks 609 on the upper and lower sides of the return plate 608, thereby driving the return plate 608 to perform linear reciprocating motion in the horizontal direction. In this way, the cleaning brush 610 will perform linear reciprocating motion along with the return plate 608, causing a horizontal relative displacement between the cleaning brush 610 and the steel cable 9, thereby improving the cleaning effect of the cleaning brush 610 and ensuring the cleanliness of the outer surface of the steel cable 9.

[0038] like Figure 6 and Figure 7As shown, the lubrication assembly includes a hollow box 801 fixed to the upper part of the sheave beam 2, and a storage tube 802 is rotatably connected to the upper part of the hole of the hollow box 801. A groove 803 is provided on the outer surface of the storage tube 802, and a ball 804 is movably clamped inside the groove 803. A partition plate 805 is provided in the hole of the hollow box 801, and a positioning block 806 is fixedly connected to the surface of the partition plate 805. The bottom end of the storage tube 802 is fixedly connected to a transmission rod 807, and the outer surface of the transmission rod 807 extending into the hollow box 801 is fixedly connected to a gear 1 808. A cylinder 809 is provided in the middle of the hollow box 801, and a long rod 810 is provided inside the cylinder 809. Both ends of the long rod 810 are rotatably connected to the inner wall of the hollow box 801, the outer surface of the bottom end of the long rod 810 is fixedly connected to a gear 2 812, and the outer surface of the long rod 810 is provided with a spiral plate 811.

[0039] When the steel rope 9 passes between the two anti-ropes 7, it will pass through the hollow box 801, and the steel rope 9 will be clamped in the groove 803 on the surface of the storage tube 802. Under the limit of the positioning block 806, it will exert a pressure on the storage tube 802, and then the steel rope 9 will drive the storage tube 802 to rotate under the action of friction during the movement of the steel rope 9. At the same time, the friction between the steel rope 9 and the ball 804 will drive the ball 804 to rotate, and the lubricating oil on the surface of the ball 804 will adhere to the outer surface of the steel rope 9, which has the effect of lubricating the steel rope 9, ensuring the smooth operation of the steel rope 9, reducing the friction between the steel rope 9 and the rope pulley, and reducing the generation of the operation The noise is reduced and the service life of the steel rope 9 is increased. In addition, the rotation of the storage tube 802 will drive the gear 1 808 to rotate through the transmission rod 807, and the gear 1 808 will mesh with the gear 2 812, which will drive the gear 2 812 and the long rod 810 on both sides to rotate. The rotation of the long rod 810 will drive the spiral plate 811 to rotate. During the rotation of the spiral plate 811, the lubricating oil will be stirred and the lubricating oil will be driven to rise and fall through the cylinder 809, so as to mix the lubricating oil distributed up and down in the hollow box 801, ensure that the lubricating oil is in a flowing state, avoid stratification and precipitation caused by the lubricating oil being stationary, and maintain the lubricating effect of the lubricating oil.

[0040] like Figure 1 and Figure 8 As shown, the rope end assembly includes a steel wire 1002 inserted into the outer surface of the steel rope 9, a rope clamp 1003 is provided at the intersection of the two ends of the steel wire 1002, an adjusting rope end 1001 is provided at the end of the steel rope 9, and a rope clamp plate 1004 is provided on the outer surface of the steel rope 9 near the adjusting rope end 1001;

[0041] After one end of the steel cable rope 9 is installed with the rope head cone sleeve, it is fixed on the rope head plate. The other end of the steel cable rope 9 passes through the rope head plate, and the steel cable rope 9 is tightened and cut at the appropriate position. The rope head combination is fixed on the rope head plate in the same way. After adjustment, the length of the rope head spring 310 is made uniform. After the rope head 1001 is adjusted and installed, the rope heads of each steel cable rope 9 are strung together with the steel wire 1002 to prevent the rope heads from spinning.
