Description

Technical Field

[0001] The utility model belongs to the technical field related to stereo garages, and in particular relates to a car lifting system and a stereo garage. Background Art

[0002] With the continuous development of the smart parking industry, the three-dimensional parking garage has ushered in continuous innovation and application to improve the lifting speed and stability of the equipment operation. At present, most of the three-dimensional parking garage lifting systems on the market adopt a four-point lifting system, which usually uses a chain to connect the four lifting points on the car platform to the counterweight, and is controlled by a drive motor in the top machine room to realize the lifting and lowering of the car platform. However, in the existing four-point lifting system, the top machine room will occupy a certain design height of the lifting shaft, and the requirements for the civil structure are relatively high, which makes the application scenarios of the above-mentioned four-point lifting system subject to certain restrictions; moreover, the existing four-point lifting system generally uses a long chain as the system transmission medium, which makes the four-point lifting system undoubtedly generate a lot of noise through vibration during the lifting movement. Utility Model Content

[0003] In view of this, it is necessary to provide a car lifting system and a stereo garage for solving the high design height of the lift shaft and the working noise.

[0004] A car lifting system is used in a civil construction shaft, and the car lifting system includes:

[0005] A hoistway steel frame structure, comprising hoistway columns, car guide rails and counterweight guide rails, wherein the car guide rails and the counterweight guide rails are both fixedly connected to the hoistway columns;

[0006] A car platform slidably connected to the car guide rail;

[0007] a counterweight assembly slidably connected to the counterweight guide rail;

[0008] A driving assembly is arranged at the bottom of the hoistway steel frame structure and is used to control the rise / descent of the car platform;

[0009] A traction rope group is transmission-connected to the driving assembly, one end of the traction rope group is connected to the counterweight assembly, and the other end of the traction rope group is divided into at least two independent traction ropes after passing through the driving assembly, and at least two of the traction ropes extend in two directions of the car platform and are connected to the car platform respectively.

[0010] It can be understood that the driving assembly that controls the rise / fall of the car platform is arranged at the bottom of the shaft steel frame structure, and a traction rope group is used to realize the power transmission when controlling the lifting and lowering of the car platform. This can, on the one hand, realize the machine room-less design of the car lifting system, so as to reduce the rigid requirements of the car lifting system for the height of the civil shaft, which not only expands the application scenarios, but also reduces the manufacturing requirements of the car lifting system, thereby reducing costs. On the other hand, the structural characteristics of the traction rope group can also be utilized to effectively reduce the noise generated when the car lifting system is working.

[0011] In one embodiment, the driving assembly includes a driving wheel, and the traction rope group can be divided into at least two independent traction ropes after winding around the driving wheel;

[0012] The car lifting system also includes a counterweight synchronous wheel group and a tension wheel group. The counterweight synchronous wheel group is arranged at the top position of the shaft steel frame structure, and the traction rope group can be wound around the counterweight synchronous wheel group, the tension wheel group and the driving wheel in sequence.

[0013] It can be understood that the traction rope group is tensioned by the tensioning wheel so that the traction rope group is always in a tensioned state. This can prevent the driving wheel from slipping when controlling the lifting of the car platform through the traction rope group and ensure the stability of the driving wheel's control over the lifting of the car platform.

[0014] In one of the embodiments, the counterweight assemblies are configured in two groups;

[0015] The number of the traction rope groups is also configured as two groups, and the two groups of the traction rope groups are respectively connected to the two groups of the counterweight assemblies, and each group of the traction rope group is divided into two independent traction ropes after passing through the driving wheel. The two traction ropes are used to connect the two hanging points of the car platform.

[0016] It can be understood that, through the above-mentioned structural setting, the car lifting system can drive the four lifting points of the car platform when working.

[0017] In one of the embodiments, the car lifting system further comprises a plurality of car synchronous wheels, and the plurality of car synchronous wheels are arranged at the top position of the hoistway steel frame structure;

[0018] The two traction ropes can be connected to the car platform after passing through the car synchronous wheel in two opposite directions.

[0019] In one embodiment, the two traction ropes are set as a first traction rope and a second traction rope; the counterweight synchronous wheel set includes a first counterweight synchronous wheel and a second counterweight synchronous wheel;

[0020] Among them, the first traction rope can be wound around the second pair of weight-synchronous wheels, the tensioning wheel group, the driving wheel and part of the car synchronous wheel in sequence; the second traction rope can be wound around the first pair of weight-synchronous wheels, the second pair of weight-synchronous wheels, the tensioning wheel group, the driving wheel and the remaining part of the car synchronous wheel in sequence.

[0021] In one of the embodiments, the car lifting system further comprises a support beam, wherein the support beam is fixedly connected to the hoistway column;

[0022] Wherein, the counterweight synchronous wheel set and the plurality of car synchronous wheels are rotatably mounted on the support beam.

[0023] It can be understood that using a support beam to carry the counterweight synchronous wheel group and multiple car synchronous wheels allows the counterweight synchronous wheel group and multiple car synchronous wheels to be integrated on the support beam, which facilitates the assembly of the counterweight synchronous wheel group and multiple car synchronous wheels on the shaft column and reduces the assembly cost.

[0024] In one embodiment, the number of the driving wheels is configured to be two;

[0025] The driving assembly also includes a driving motor and a coupling. The two driving wheels are arranged on two opposite sides of the car platform, one of the driving wheels is drivingly connected to the driving motor, and the other driving wheel is drivingly connected to the driving motor through the coupling.

[0026] It can be understood that, through the structural setting of the above-mentioned drive component, the car lifting system can select standard products on the market to realize the control of the lifting movement of the car platform. This can reduce costs on the one hand, and facilitate the subsequent maintenance or replacement of the drive component on the other hand.

[0027] In one embodiment, one side of the counterweight assembly is disposed close to the shaft column on one side of the shaft steel frame structure, and an installation space is reserved between the other side of the counterweight assembly and the shaft column on the other side of the shaft steel frame structure;

[0028] Wherein, the driving assembly is accommodated in the installation space.

[0029] It can be understood that the drive assembly is arranged in the installation space reserved between the shaft column and the counterweight assembly in the shaft steel structure, which can form a compact assembly structure and save the shaft space.

[0030] In one embodiment, the car lifting system further comprises a buttress assembly, and the hoistway column can be fixedly connected to the hoistway side wall through the buttress assembly;

[0031] Wherein, a buffer is arranged between the wall support assembly and the shaft column.

[0032] It is understandable that the connection between the supporting wall assembly and the shaft column is buffered by a buffer, which can effectively reduce the rigid vibration of the car platform during the lifting movement, and has the effect of further reducing the working noise of the car lifting system.

[0033] In addition, the present application also seeks protection for a stereoscopic car park, including the above-mentioned car lifting system.

[0034] Due to the application of the above technical solution, the utility model has the following advantages compared with the prior art:

[0035] The car lifting system and multi-story car park for which protection is sought in the present application arrange the driving assembly for controlling the rise / descent of the car platform at the bottom of the shaft steel frame structure, and use a traction rope group to realize power transmission when controlling the lifting and lowering of the car platform. This can, on the one hand, realize a machine room-less design of the car lifting system, thereby reducing the rigid requirements of the car lifting system for the height of the civil shaft, which not only expands the application scenarios, but also reduces the manufacturing requirements of the car lifting system, thereby reducing costs. On the other hand, the structural characteristics of the traction rope group can also be utilized to effectively reduce the noise generated when the car lifting system is working.

[0047] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0048] like Figures 1 to 3As shown, a car lifting system 100 provided in an embodiment of the present application includes a shaft steel frame structure 10, a car platform 20, a counterweight assembly 30, a drive assembly 40 and a traction rope group 50. The shaft steel frame structure 10 includes a shaft column 11, and a car guide rail 12 and a counterweight guide rail 13 are fixedly connected to the shaft column 11; the car platform 20 is slidably connected to the car guide rail 12; the counterweight assembly 30 is slidably connected to the counterweight guide rail 13; the drive assembly 40 is arranged at the bottom position of the shaft steel frame structure 10, and is used to control the rise / descent of the car platform 20; the traction rope group 50 is transmission-connected to the drive assembly 40, one end of the traction rope group 50 is connected to the counterweight assembly 30, and the other end of the traction rope group 50 is divided into at least two independent traction ropes after passing through the drive assembly 40, and the at least two traction ropes extend in two directions of the car platform 20 and are connected to the car platform 20 respectively. That is to say, the car lifting system 100 of the present application places the driving assembly 40 for controlling the lifting of the car platform 20 downward, so that the design of the car lifting system 100 without a machine room can be realized. Here, the number of shaft columns 11 is configured as four, and the four shaft columns 11 are located in the civil shaft 200, and can be specifically erected at the bottom of the civil shaft by welding embedded parts or fixing with steel expansion bolts; and the car guide rails 12 and the counterweight guide rails 13 are specifically fixed to the four shaft columns 11 with bolts to provide a basis for the lifting and lowering operation of the car platform 20 and the counterweight assembly 30.

[0049] It can be understood that the driving assembly 40 for controlling the rise / fall of the car platform 20 is arranged at the bottom position of the shaft steel frame structure 10, and the traction rope group 50 is used to realize the power transmission when the car platform 20 is raised and lowered. In this way, on the one hand, the machine room-less design of the car lifting system 100 can be realized, so as to reduce the rigid requirements of the car lifting system 100 for the height of the civil shaft, which not only has the effect of expanding the application scenarios, but also reduces the manufacturing requirements of the car lifting system 100, and has the effect of reducing costs; on the other hand, the structural characteristics of the traction rope group 50 can also be utilized to effectively reduce the noise generated when the car lifting system 100 is working.

[0050] It should be noted that the traction ropes in the traction rope group 50 are configured as steel wire ropes, or other nylon ropes that can meet the application of multi-story parking garages. Obviously, the noise generated by the traction ropes during power transmission is much lower than the noise generated by the transmission chain during power transmission. Therefore, the noise generated when the car lifting system 100 is working can be reduced.

[0051] like Figure 1As shown, the car lifting system 100 also includes a supporting wall assembly 110, and the shaft column 11 can be fixedly connected to the shaft side wall 201 of the civil shaft 200 through the supporting wall assembly 110; wherein, a buffer (not shown) is provided between the supporting wall assembly 110 and the shaft column 11, so as to use the buffer to buffer the connection between the supporting wall assembly 110 and the shaft column 11, which can effectively reduce the rigid vibration of the car platform 20 during the lifting movement, and has the effect of reducing the working noise of the car lifting system 100. Here, the buffer can be made of soft materials with buffering properties such as rubber and polyurethane. It should be noted that the structural composition of the supporting wall assembly 110 can adopt the existing conventional method, which will not be elaborated here.

[0052] like Figure 4 As shown, the driving assembly 40 includes a driving motor 41, a coupling 42 and two driving wheels 43, the two driving wheels 43 are arranged on two opposite sides of the car platform 20, one of the driving wheels 43 is connected to the driving motor 41 by transmission, and the other driving wheel 43 is connected to the driving motor 41 by transmission through the coupling 42. That is to say, the driving motor 41 has two power output shafts, and here, specifically, a double-axis reducer 411 can be integrated on the driving motor 41, and the double-axis reducer 411 is used to respectively connect to one of the driving wheels 43 and the coupling 42 by transmission; and the traction rope group 50 can be divided into at least two independent traction ropes after winding around the driving wheel 43.

[0053] Since the driving motor 41, coupling 42 and driving wheel 43 constituting the driving assembly 40 are all standard products on the market, the driving assembly 40 has the advantages of reducing costs and facilitating subsequent maintenance or replacement of the driving assembly 40 compared to the driving method in which the active component of the power system in the existing multi-story parking garage drives the driven component.

[0054] like Figure 4 As shown, the coupling 42 is configured as a cross-axis universal coupling 421. By utilizing the structural characteristics of the cross-axis universal coupling 421, the coupling 42 not only has a large angle compensation capability but also has a compact and reasonable structure. Compared with other types of couplings with the same rotation diameter, the coupling 42 transmits a larger torque and has a stronger carrying capacity. Therefore, when the coupling 42 is applied to the car lifting system 100, the matching range of the coupling 42 is more advantageous, and it has the characteristics of high transmission efficiency, and can be applied to high-power transmission, with obvious energy-saving effects. In addition, the car lifting system 100 can be carried smoothly, with low noise, and easy to disassemble and maintain, which greatly saves the later maintenance costs.

[0055] like Figure 2As shown, the number of counterweight assemblies 30 is also configured as two groups, and the number of traction rope groups 50 is also configured as two groups. The two groups of traction rope groups 50 are respectively connected to the two groups of counterweight assemblies 30, and each group of traction rope groups 50 is divided into two independent traction ropes after passing through the driving wheel 43. The two traction ropes are used to connect the two hanging points of the car platform 20. Here, the hanging point of the car platform 20 specifically refers to the installation part on the car platform 20 for the traction rope to be connected. The number of the above-mentioned drive assemblies 40 is set to match the number of counterweight assemblies 30. In one embodiment, one side of the counterweight assembly 30 is arranged close to the shaft column 11 on one side of the shaft steel frame structure 10, and the other side of the counterweight assembly 30 is left with an installation space between the shaft column 11 on the other side of the shaft steel frame structure 10, and the drive assembly 40 is accommodated in the installation space to form a compact assembly structure and save the space occupied by the shaft.

[0056] like Figure 2 , Figure 5 As shown, the car lifting system 100 further includes a counterweight synchronous wheel set 61, a tension wheel set 62 and a plurality of car synchronous wheels 63, the counterweight synchronous wheel set 61 and the plurality of car synchronous wheels 63 are all arranged at the top position of the hoistway steel frame structure 10, and the traction rope set 50 can be wound around the counterweight synchronous wheel set 61, the tension wheel set 62 and the driving wheel 43 in sequence; wherein, the two traction ropes can be wound around the car synchronous wheels 63 in two opposite directions and then connected to the car platform 20. In this way, the arrangement of the traction rope set 50 in the car lifting system 100 is specifically realized.

[0057] It can be understood that the traction rope group 50 is tensioned by the tensioning wheel group 62 so that the traction rope group 50 is always in a tensioned state. This can prevent the driving wheel 43 from slipping when controlling the lifting and lowering of the car platform 20 through the traction rope group 50, and ensure the stability of the driving wheel 43 in controlling the lifting and lowering of the car platform 20.

[0058] like Figure 6 , Figure 7 As shown, each traction rope group 50 includes a first traction rope 51 and a second traction rope 52, the first traction rope 51 and the second traction rope 52 are independently arranged, and the first traction rope 51 and the second traction rope 52 can be wound around the corresponding driving wheel 43. In other words, each counterweight assembly 30 can be respectively connected to the car platform 20 through the first traction rope 51 and the second traction rope 52, and realize the four-point driving of the car platform 20.

[0059] Among them, the counterweight synchronous wheel group 61 includes a first counterweight synchronous wheel 611 and a second counterweight synchronous wheel 612; the first traction rope 51 can be wound around the second counterweight synchronous wheel 612, the tensioning wheel group 62, the driving wheel 43 and part of the car synchronous wheel 63 in sequence; the second traction rope 52 can be wound around the first counterweight synchronous wheel 611, the second counterweight synchronous wheel 612, the tensioning wheel group 62, the driving wheel 43 and the remaining part of the car synchronous wheel 63 in sequence. Here, the first counterweight synchronous wheel 611 and the second counterweight synchronous wheel 612 are arranged at the same height position, and a plurality of car synchronous wheels 63 are arranged above the counterweight synchronous wheel group 61 and at the same height position. Specifically, the number of car synchronous wheels 63 can be configured as four, wherein the first traction rope 51 extends outwards through two of the car synchronous wheels 63, and then downwardly connects to the corresponding suspension points on the car platform 20, and the second traction rope 52 extends outwards through the other two car synchronous wheels 63, and then downwardly connects to the corresponding suspension points on the car platform 20. Of course, in other embodiments, the number of car synchronous wheels 63 can also be configured as five, six, or even more. In addition, in order to match the installation position of the drive assembly 40 to improve the transmission efficiency; the installation position of some car synchronous wheels 63 is set up and down corresponding to the drive assembly 40, and the installation position of some car synchronous wheels 63 is set corresponding to the suspension points of the car platform 20. After passing through the driving assembly, the traction rope group 50 extends separately to both sides at the part of the car synchronous wheel 63 placed above the driving assembly 40. In one embodiment, the number of the car synchronous wheels 63 is configured as four, of which three car synchronous wheels 63 are configured above the driving assembly 40, and the other car synchronous wheel 63 is configured to correspond to the suspension point position on the opposite side of the car platform 20. After passing through one of the three car synchronous wheels 63, the first traction rope 51 continues to extend outward, continues to pass through another car synchronous wheel 63 located on the opposite side of the car platform 20, and then extends downward to connect with the suspension point on the car platform 20; the second traction rope 52 continues to extend outward and downward to connect with the suspension point on the car platform 20 after passing through the other two of the three car synchronous wheels 63.

[0060] like Figure 5 As shown, the car lifting system 100 further includes a support beam 64, which is fixedly connected to the shaft column 11; wherein the counterweight synchronous wheel set 61 and the plurality of car synchronous wheels 63 are rotatably mounted on the support beam 64. That is, the counterweight synchronous wheel set 61 and the plurality of car synchronous wheels 63 can be assembled on the shaft column 11 with the support beam 64 as the mounting basis, which can facilitate the assembly of the counterweight synchronous wheel set 61 and the plurality of car synchronous wheels 63 on the shaft column 11 and play a role in reducing the assembly cost.

[0061] In addition, the present application also seeks protection for a stereoscopic car park, including the above-mentioned car lifting system 100.

[0062] The technical features of the above embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0063] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present invention, and are not intended to limit the present invention. As long as they are within the spirit of the present invention, appropriate changes and modifications to the above embodiments are within the scope of protection required by the present invention.
