Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

The utility model aims to provide a system for driving a plurality of lifting vehicle plates by a single motor mechanism, which solves the problems of the prior art, and has a simple structure and does not need to additionally increase the width dimension of a parking space.

In order that the above-recited objects, features and advantages of the present utility model will become more readily apparent, a more particular description of the utility model will be rendered by reference to the appended drawings and appended detailed description.

The traction device of the lifting and transverse moving parking equipment in the prior art is divided into a winding drum steel wire rope traction mode and a chain wheel chain traction mode, the basic structures of the traction devices of the two modes are the same, a power source is a gear motor and an external reduction mechanism (usually a chain wheel chain reduction mechanism), a driven transmission part of the external reduction mechanism is fixedly arranged on a transversely arranged installation shaft, the left end and the right end of the installation shaft are respectively fixedly provided with a chain wheel or a winding drum, and the chain wheel drives a chain to realize lifting of a lifting car plate (more than two layers of equipment) or the winding drum tows the steel wire rope to realize lifting of the lifting car plate (more than three layers of equipment).

The traction device is related to the operation of the traction device and comprises a chain rope loosening detection mechanism and a falling prevention mechanism; the only purpose of the chain rope loosening detection mechanism in the prior art is to detect whether loosening and breakage of a steel rope or a chain occur in the running process of equipment; the anti-falling mechanism in the prior art has the function of preventing the lifting truck plate from falling when the upper layer is kept still, the lifting truck plate and the anti-falling mechanism are not contacted under normal conditions, and the control logic in the prior art also does not allow the lifting truck plate to be contacted with the anti-falling mechanism.

Referring to fig. 1, fig. 1 is a schematic view showing a lifting driving of a two-layer lifting vehicle plate of a two-layer lifting and traversing parking device in the prior art, and a driving device of a top layer lifting vehicle plate with more than two layers is similar to the driving device. The figure shows a lifting driving schematic diagram of a three-parking-place two-layer lifting and transverse moving parking device with one motor driving one lifting vehicle plate in the prior art, and the front end of the mechanical transmission is a chain wheel and chain speed reducing mechanism. The driving device of the top lifting vehicle plate with more than two layers is similar to the driving device. As can be seen from fig. 1: the upper left side is a top parking space I01 a, a motor speed reducer I02 a outputs and drives a driving chain wheel I03 a, a driving chain I07 a drives a driven chain wheel I09 a and drives a driving shaft I05 a to rotate, a right traction wheel I06 a is driven to drag a right traction chain I08 a, a left traction wheel I04 a is driven to drag a left traction chain I11 a, and finally a traction lifting vehicle board I10 a rises or falls. Similarly, the upper middle part is a top parking space II 01b, the motor speed reducer II 02b outputs and drives the driving chain wheel II 03b, the driving chain II 07b drives the driven chain wheel II 09b and drives the driving shaft II 05b to rotate, the right traction wheel II 06b is driven to drag the right traction chain II 08b, the left traction wheel II 04b is driven to drag the left traction chain II 11b, and finally the traction lifting vehicle board II 10b rises or falls. The upper right side is a top parking space three 01c, a motor speed reducer three 02c outputs and drives a driving chain wheel three 03c, a driven chain wheel three 09c is driven by a driving chain three 07c and drives a driving shaft three 05c to rotate, a right traction wheel three 06c is driven to traction a right traction chain three 08c, a left traction wheel three 04c is driven to traction a left traction chain three 11c, and finally a traction lifting vehicle plate three 10c rises or falls. Obviously, the first motor speed reducer 02a, the second motor speed reducer 02b and the third motor speed reducer 02c are respectively and independently arranged and independently run, and one lifting vehicle plate needs one motor and one set of transmission chain.

According to the technical scheme, a set of motor mechanism replaces a plurality of motor speed reducers; the driving transmission part of the external speed reducing mechanism is changed into a clutchable mode; the chain rope loosening detection mechanism in the prior art is reserved, but has a newly added detection function; the anti-falling mechanism in the prior art is reserved, but the control logic is changed, and the lifting truck plate is contacted with the anti-falling mechanism when the upper layer is kept still (thus, an additional benefit is also produced, namely, the lifting truck plate does not need to bear the load of the lifting truck plate and the vehicle when the upper layer is kept still, and the service life of the traction wire rope or the traction chain can be effectively prolonged).

Therefore, the technical scheme of the utility model is to purposefully combine the motor mechanism, the external speed reducing mechanism, the chain rope loosening detecting mechanism and the anti-falling mechanism into a new system. By adopting the technical scheme of the utility model, a set of lifting and transverse moving parking equipment can drive all lifting vehicle plates on the top layer of the equipment by using only one motor mechanism. If the number of the lifting vehicle plates on the top layer of the equipment is large, the plurality of parking spaces which are arranged in series can be divided into an area, and the lifting vehicle plates on the top layer of the parking spaces in the area are driven by one motor mechanism.

Specifically, the system for driving a plurality of lifting vehicle plates by using a single motor mechanism comprises the lifting vehicle plates, a parking space, a frame, a motor mechanism, a coupling mechanism and a traction mechanism. One lifting car plate corresponds to one top-layer parking space; the frame is installed in the top on equipment ground, and top rear width direction is provided with the rear cross beam that strides across a plurality of top parking stalls. The motor mechanism is one set and is arranged on the rear cross beam of the tail end parking space at one side of the frame, the output shaft faces the parking space at the other end, and the central line of the motor mechanism is parallel to the rear cross beam. The coupling mechanism comprises a coupling, an extension shaft and a bearing seat; the coupling is one of the following two ways: in the first mode, one end of the integral type is a driving end, and the other end of the integral type is a driven end; and in a second mode, the assembly type consists of two parts which are connected through a screw rod or a pin or a middle piece, wherein one part is an active end, and the other part is a passive end.

Obviously, the general form of the integral coupler is a coupler sleeve with an inner hole provided with a spline or a flat key groove; the assembled coupler comprises a rigid coupler, an elastic coupler, a flexible coupler, a chain wheel and chain coupler, an end face tooth coupler, a universal coupler and other common couplers.

The extension axle is arranged across the top parking space. The number of the bearing seats is at least one, and the bearing seats are arranged on the rear cross beam and are used for supporting the extension shaft. The coupling mechanism adopts one of the following two modes:

in the first mode, the coupling mechanism is one set, the driving end of the coupling is tightly connected with the output shaft of the motor mechanism, the driven end of the coupling is tightly connected with one end of the extension shaft, and the other end of the extension shaft spans all top-layer parking spaces.

In the second mode, the number of the lifting vehicle plates is N, the number of the coupling mechanisms is N-1, and each coupling mechanism comprises a coupling, an extension shaft and a plurality of bearing seats; starting from the top-layer parking space where the motor mechanism is located, each extension shaft spans the front top-layer parking space and the rear top-layer parking space. The second mode can be specifically described as: the driving end of the coupler of the first set of coupling mechanism is fixedly connected with the output shaft of the motor mechanism, the driven end of the coupler is fixedly connected with one end of the extension shaft, and the extension shaft transversely spans the top-level parking space where the motor mechanism is positioned and the next top-level parking space immediately adjacent to the top-level parking space, which is equivalent to the axial extension of the output shaft of the motor mechanism from the top-level parking space where the motor mechanism is positioned to the next top-level parking space; then, the driving end of the coupler of each set of coupler mechanism is tightly connected with the tail end of the extension shaft of the former set of coupler mechanism, and the driven end is tightly connected with one end of the extension shaft of the coupler mechanism; the extension shaft of the coupling mechanism transversely spans the parking space and the next top parking space, which is close to the parking space, and is equivalent to the axial extension of the extension shaft of the previous coupling mechanism from the top parking space to the next top parking space.
