Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical parking equipment, and specifically relates to a double-drive two-hanging-point lifting device. Background Art

[0002] Mechanical parking equipment refers to a new type of parking equipment that utilizes space resources to park vehicles in a three-dimensional manner, saving land and maximizing its use. The biggest advantage of mechanical parking equipment is that it can make full use of urban space, and is known as the "energy saver" of urban space. The problem of nowhere to park vehicles is the result of the social, economic and transportation development of the city to a certain extent. The development of mechanical parking equipment has a history of nearly 40 to 50 years abroad, especially in Japan, and has been successful both in terms of technology and experience. my country also began to research and develop mechanical three-dimensional parking equipment in the early 1990s, and it has been nearly 30 years since then. Since the ratio of residents to parking spaces in many newly built communities is 1:1.2, in order to solve the contradiction between the area occupied by parking spaces and the commercial area of ​​residents, mechanical three-dimensional parking equipment has been accepted by the majority of users for its unique characteristics of small average single-vehicle area. As an important part of the three-dimensional garage, the elevator lifting system is responsible for the up and down handling of vehicles. Generally, there are three types of wire rope lifting, chain lifting and rack lifting. Among them; wire rope lifting has low noise, but poor load-bearing capacity and high elasticity, requiring multiple ropes to be used in parallel, which increases the difficulty of the lifting system; chain lifting has large load-bearing capacity, but loud noise and difficulty in turning; rack lifting has large load-bearing capacity and low noise, but requires high manufacturing and installation precision and high cost. Summary of the invention

[0003] The utility model aims to overcome the above disadvantages and provide a dual-drive two-hanging-point lifting device which has low cost, low noise, low requirements on manufacturing and installation precision and easy steering transmission.

[0004] The purpose of the utility model and the solution of its main technical problems are achieved by adopting the following technical solutions:

[0005] The utility model discloses a double-drive two-hanging-point lifting device, comprising a counterweight, a driving device, a lifting chain mechanism, a crossbeam, a synchronous chain mechanism, and a synchronization mechanism, and is characterized in that a synchronization mechanism is installed in the middle of the crossbeam, and driving devices are respectively installed at both ends, a synchronous chain mechanism is installed on the synchronization mechanism, and a synchronous chain mechanism and a lifting chain mechanism are respectively installed on the driving device, and one end of the lifting chain mechanism is connected to the counterweight.

[0006] The driving device is composed of a reduction motor, a transmission shaft, a bearing, a sprocket group A, a sprocket group B, and a first machine base. Both ends of the sprocket group A are installed on the machine base through bearings. The sprocket group A is connected to the transmission shaft, and the transmission shaft is connected to the reduction motor. The reduction motor and the sprocket group B are installed on the first machine base. The sprocket group A and the sprocket group B are respectively composed of a plurality of fixedly installed sprockets.

[0007] The lifting chain mechanism is composed of a counterweight chain hanger, a counterweight chain, and a lifting chain hanger. The two ends of the counterweight chain are respectively connected to the counterweight chain hanger and the lifting chain hanger, and the middle part is installed on sprocket group A and sprocket group B.

[0008] The synchronous chain mechanism is composed of a synchronous chain A and a synchronous chain B, and the synchronous chain A and the synchronous chain B are respectively installed on the synchronous mechanism.

[0009] The synchronization mechanism consists of a tensioning bolt, a steering wheel, a driving wheel, a tensioning wheel, a second machine base, and a connecting seat. The second machine base is respectively provided with a steering wheel and a tensioning wheel at both ends, a driving wheel is provided in the middle, and tensioning bolts are respectively provided at both ends. The tensioning bolts are connected to the connecting seat, and the connecting seat is installed on the crossbeam by bolts. The synchronization chain A is respectively connected to the steering wheel, the driving wheel, and the tensioning wheel, and the synchronization chain B is connected to the driving wheel.

[0010] The driving wheel is provided with two fixed sprocket wheels.

[0011] Compared with the prior art, the utility model has obvious beneficial effects; from the above technical scheme, it can be seen that: by installing a synchronization mechanism in the middle of the beam, driving devices are installed at both ends, a synchronization chain mechanism is installed on the synchronization mechanism, and a synchronization chain mechanism and a lifting chain mechanism are installed on the driving device respectively. One end of the lifting chain mechanism is connected to a counterweight block, and the counterweight block is a balancing weight component that reduces the driving power and balances the weight with the lifting platform. The driving device 2 pulls the lifting platform up and down by changing the length of the chains on both sides of the sprocket group A. The reduction motor mainly converts electrical energy into torque, and the torque is transmitted to the sprocket group A through the transmission shaft. The sprocket group A is composed of four groups of sprockets, three of which are used to pull the counterweight chain. One end of the counterweight chain is directly vertically downward, and the other end is installed downward after passing through the sprocket group B for guidance; one group is used to pull the left synchronous chain A or the right synchronous chain B. The lifting chain mechanism is connected to the counterweight block through the counterweight chain hanger at one end, and connected to the lifting platform through the lifting chain hanger at the other end. Its function is to change the height of the chain hangers at the ends of the chain on both sides of the sprocket through the rotation of the sprocket group A, so as to drive the lifting platform to rise or fall. The crossbeam mainly serves as an installation for the driving device and the synchronous mechanism, and is welded with profiles, has sufficient rigidity, reduces the amount of force deformation, and makes the operation of each moving part of the utility model reliable. The synchronous chain mechanism is to ensure that the counterweight chains driven by the two sets of driving devices run synchronously. The synchronous chain mechanism is used to connect the two driving devices in series through the synchronous mechanism, so that the lifting chain mechanism can be lifted and lowered synchronously. The synchronous mechanism is to ensure that the lifting chain mechanisms driven by the two sets of driving devices run synchronously and in opposite directions. By using the sprocket transmission method, the two sets of drives are connected to the synchronization mechanism through the synchronization chain mechanism, so that they can be forced to synchronize by mechanical structure. Compared with the prior art, the cost is low: two sets of independent drive devices are adopted, and two chain hanging points are adopted, which reduces the number of hanging points and large force transmission, makes the drive better arranged and compact, and is more convenient for transmission design, reduces the space occupied, and reduces the cost. The number of hanging points is reduced, and two independent drive devices are adopted, which makes the transmission simpler, without transmitting large forces and torques, subtracts the gear transmission links, reduces the noise value, and has low noise. All adopt chain transmission, and all are designed with threaded tensioning mechanisms, subtracting the high-precision gear meshing links, reducing the manufacturing and installation precision, and low manufacturing and installation precision. In short, the utility model has low cost, low noise, low requirements for manufacturing and installation precision, and is easy to turn to transmission. BRIEF DESCRIPTION OF THE DRAWINGS
