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 and whose 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 the elevator save time, effort, safety and smoothness to carry people and goods up and down in 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 machine beam, a main machine and a counterweight sheave seat are arranged on the main machine beam, a traction wheel is arranged on the main machine, a counterweight side fixed pulley and a counterweight side rope head are arranged on the counterweight sheave seat, the counterweight side rope head is located between the counterweight side fixed pulley and the traction wheel, and also includes a first pair of re-entry rope wheels and a second pair of re-entry rope wheels, and a traction rope is arranged on the traction wheel, through the position distribution of the traction wheel, the counterweight side fixed pulley, and the counterweight side rope head, the spacing between the first pair of re-entry rope wheels and the second pair of re-entry rope wheels is shortened, and 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 rate of the shaft.

[0016] Beneficial effects of the present invention:

[0017] 1. This type of heavy-duty passenger and freight elevator driving structure has a shock-absorbing component arranged at the bottom of the traction machine. The vibration generated during the operation of the traction machine will be transmitted to the mounting plate, which will convert the vibration into the swing of the mounting plate. A part of the kinetic energy of the vibration is converted into the internal energy of the friction between the clamp and the round roller.

[0018] 2. This type of heavy-duty passenger and freight elevator driving structure, by arranging a cleaning component on the outside of the steel cable rope, utilizes the rotation of the anti-ropes wheel and the transmission of the main pulley and the auxiliary pulley to drive the worm to rotate, and then drives the half gear to rotate, so that the return plate can make a linear reciprocating motion in the horizontal direction, so that there is a horizontal relative displacement between the cleaning brush and the steel cable rope, which improves the cleaning effect of the cleaning brush and ensures the cleanliness of the outer surface of the steel cable rope.

[0019] 3. This type of heavy-duty passenger and freight elevator driving structure has a lubrication component arranged on the upper part of the sheave beam, and the steel cable rope is clamped in the groove on the surface of the storage tube.

DETAILED DESCRIPTION

[0031] 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 in conjunction with specific embodiments.

[0032] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the present invention should be understood by people with ordinary skills in the field to which the present invention belongs.

"Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0033] like Figures 1 to 8 As 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 arranged at the top of the main beam 1, and a traction machine 4 is arranged on the upper part of the shock-absorbing assembly. A reverse pulley 1 5 is arranged on the upper part of the main beam 1, and a cleaning assembly is arranged on the side of the reverse pulley 1 5. Two reverse pulleys 2 7 are symmetrically distributed on the upper part of the sheave beam 2, and a lubrication assembly is arranged between the two reverse pulleys 2 7. A steel rope 9 is arranged on the outer surface of the traction wheel at the end of the traction machine 4, and a rope head assembly is arranged 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. The steel rope 9 is sequentially interspersed in the cleaning assembly and the lubrication assembly, and the cleaning assembly is attached to the reverse pulley 1 5 for operation. The main beam 1 has reinforcing 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 traction ratio of four to one can maximize the use of the hoistway space, save twice the electric energy compared with the traditional traction ratio drive structure of two to one, and save energy and reduce consumption.

[0034] 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 positioning of the anti-rope pulley 2 7. The steel rope 9 synchronously pulls the counterweight block up and down under the redirection positioning of the anti-rope pulley 1 5 to play 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 weaken 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 up the dust and debris adhered to the steel wire 1002 rope to prevent dust and debris from being entangled on the rope pulley. The lubrication assembly can lubricate the steel rope 9 to ensure the smoothness of the operation of the steel rope 9, reduce the friction between the steel rope 9 and the rope pulley, reduce the noise generated by the operation, and improve the service life of the steel rope 9.

[0035] like Figure 2 and Figure 3 As shown, the shock absorbing assembly includes a bottom plate 301 fixed to the top of the main beam 1, a support 302 is arranged 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, a mounting plate 304 is fixedly connected to the top of the clamp 305, the traction machine 4 is arranged on the upper surface of the mounting plate 304, a baffle 306 is arranged on the upper surface of the bottom plate 301, a slide groove 309 is opened through the partition of the baffle 306, and the inner part of the slide groove 309 is slidably connected to Slider 308, the outer surface of the slider 308 is hinged with a support rod 307, one end of the support rod 307 away from the slider 308 is hinged to the lower surface of the mounting plate 304, a spring 310 is provided on one side of the slider 308, and a rubber ring 313 is provided on the other side, the lower parts of both sides of the clamp 305 are fixedly connected with side plates 311, and the upper surface of the bottom plate 301 is provided with a pad 312, and two pads 312 are provided and symmetrically distributed on both sides of the support 302, and the lower surface of the side plate 311 abuts against the upper surface of the pad 312;

[0036] 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. Both horizontal and vertical vibrations will drive the mounting plate 304 to swing slightly around the round roller 303, converting part of the kinetic energy of the vibration into the internal energy of the friction between the clamp 305 and the round roller 303, and the side plate 311 will squeeze the pad 312 during the swing of the mounting plate 304. , 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 to reduce the elastic force of the spring 310, thereby playing an effect of flexibly reducing and balancing the swing. The flexible reduction method can ensure the stability of the connection between the traction machine 4 and the mounting plate 304.

[0037] like Figure 4 and Figure 5 As shown, the cleaning assembly includes a frame 601 fixed to the middle of the main beam 1, the end of the anti-ropes pulley-5 shaft rod is fixedly connected to the main pulley 602, the outer surface of the main pulley 602 is meshedly connected to the secondary pulley 604 through the belt 603, the middle of the secondary pulley 604 is fixedly connected to a 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 a worm wheel 606, the worm 605 is meshedly connected to the worm wheel 606, the middle of the side of the worm wheel 606 is fixedly connected to a half gear 607, and the half gear 607 is fixedly connected to the middle of the side of the worm wheel 606. 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 near the side of the half gear 607. Two racks 609 are provided and 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, and 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 provided inside the track 611;

[0038] The steel rope 9 will pass through the cleaning assembly as the car rises and falls, and will come into contact with and vertically displace the cleaning brush 610. 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 anti-ropes 5 will rotate under the traction of the steel rope 9, thereby driving the main pulley 602 at the end of the anti-ropes 5 shaft rod to rotate, and the secondary pulley 604 and the worm 605 will 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 will rotate faster, and the worm 605 will rotate faster. During the rotation, the worm wheel 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 mesh with the racks 609 on the upper and lower sides of the return plate 608, and then drive the return plate 608 to make a linear reciprocating motion in the horizontal direction. In this way, the cleaning brush 610 will make a linear reciprocating motion with the return plate 608, so that the cleaning brush 610 and the steel cable 9 will have a relative displacement in the horizontal direction, thereby improving the cleaning effect of the cleaning brush 610 and ensuring the cleanliness of the outer surface of the steel cable 9.

[0039] like Figure 6 and Figure 7 As shown, the lubrication assembly includes a hollow box 801 fixed on the upper part of the rope pulley beam 2, 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 arranged in the hole of the hollow box 801, a positioning block 806 is fixedly connected to the surface of the partition plate 805, a transmission rod 807 is fixedly connected to the bottom end of the storage tube 802, and a gear 1 808 is fixedly connected to the outer surface of one end of the transmission rod 807 extending into the hollow box 801, a cylinder 809 is arranged in the middle part of the hollow box 801, a long rod 810 is arranged inside the cylinder 809, both ends of the long rod 810 are rotatably connected to the inner wall of the hollow box 801, a gear 2 812 is fixedly connected to the outer surface of the bottom end of the long rod 810, and a spiral plate 811 is arranged on the outer surface of the long rod 810;

[0040] When the steel cable rope 9 passes between the two anti-ropes 7, it will pass through the hollow box 801, and the steel cable rope 9 will be clamped in the groove 803 on the surface of the storage tube 802, and will exert a compressive force on the discharge tube under the limit of the positioning block 806, so that the steel cable rope 9 will drive the storage tube 802 to rotate under the action of friction during its movement, and at the same time, the friction between the steel cable 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 cable rope 9, which has the effect of lubricating the steel cable rope 9, ensuring the smoothness of the operation of the steel cable rope 9, reducing the friction between the steel cable rope 9 and the rope wheel, and reducing the noise generated during the operation. The sound is improved, and the service life of the steel cable 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. The gear 1 808 meshes with the gear 2 812, and then drives 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 stationary lubricating oil, and maintain the lubricating effect of the lubricating oil.

[0041] like Figure 1 and Figure 8 As shown, the rope head assembly includes a steel wire 1002 inserted and arranged on the outer surface of the steel cable rope 9, a rope clamp 1003 is arranged at the intersection of both ends of the steel wire 1002, an adjusting rope head 1001 is arranged at the end of the steel cable rope 9, and a rope clamp plate 1004 is arranged on the outer surface of the steel cable rope 9 near the adjusting rope head 1001;

[0042] 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 off at a suitable position. The rope head assembly 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.
