Description

Technical Field

[0001] The invention relates to the field of parking equipment, in particular to a leveling lifting device for a parking equipment trolley. Background Art

[0002] At present, the positioning devices in parking equipment mostly adopt two forms: leveling safety hook and fixed seat guided pin. The leveling safety hook form is mainly used for secondary safety protection of moving parts in lifting operation. When the lifting platform is leveled and positioned, it must be stopped at a certain distance from the leveling height, and then the motor is reversed to make the lifting platform descend and hooked on the fixed seat with a hook. This form of action is more complicated and wastes time. The fixed seat guided pin form is difficult to process, the cost is high, and the friction resistance is large, requiring a large power, which is not conducive to energy saving and environmental protection. Summary of the invention

[0003] In order to overcome the above-mentioned problems of the prior art, the present invention provides a leveling lifting device for a parking equipment trolley, which can not only avoid the disadvantages of the existing form, but also is more convenient to process, save electricity and save costs.

[0004] The technical solution adopted by the present invention to solve its technical problems is: a leveling lifting device for a parking equipment trolley, comprising a power detection component, a flap, a leveling component, a supporting component, a transmission shaft and a bearing; two groups of supporting components are respectively located on the left and right sides of the leveling component, and bearings are installed at both ends of the opposite sides of the two groups of supporting components with bolts, a transmission shaft is installed between the two bearings on each group of supporting components, and a flap is installed on the transmission shaft; the two ends of the supporting component are connected to one end of the power detection component, and the flap is hinged to the other end of the power detection component through a pin shaft.

[0005] The power detection device comprises an electric push rod with a stroke of 150 mm, on which an extended-in-place detection switch and a return-in-place detection switch are arranged, and the end of the electric push rod is hinged to a mounting seat connected to the supporting component.

[0006] The flap comprises a rotating sleeve and a steel plate. The top of the rotating sleeve is connected to the steel plate. The rotating sleeve is provided with a connecting hole matched with the pin shaft.

[0007] The top surface of the leveling component is a horizontal surface, and is a component that needs to be leveled and protected for safety.

[0008] The supporting component comprises a frame, connecting steel and height adjusting bolts. Two groups of connecting steel are installed on one side of the frame, and the height adjusting bolts are installed on the connecting steel.

[0009] The transmission shaft is processed from a bar shaft, and the bearing and the flap can be installed on it. Matching fastening nuts are arranged at both ends of the rotating shaft.

[0010] The bearing is a self-aligning bearing. The rotation of the flap drives the transmission shaft to rotate around the self-aligning bearing. Two self-aligning bearings with seats are used as guide components, which not only ensures the coaxiality of the flap latch and prevents jamming due to coaxiality error, but also ensures sufficient strength and saves costs.

[0011] The beneficial effects of the present invention are:

[0012] (1) The power detection component adopts an electric push rod, which is small in size and easy to install.

[0013] (2) The flap is used as the leveling lifting device, which has large output torque, sufficient rigidity, large lifting height, and no-load starting, and has low requirements for the push rod.

[0014] (3) Using bearings as fixed parts of the shaft can achieve high self-adjusting accuracy and simple processing.

[0015] (4) It can not only correct the problem of low precision caused by the electrical control of the parking position during the movement of the moving parts, but also avoid equipment failure caused by loose chains or wire ropes. It can be widely used in vertical lifting parking equipment. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them.

[0026] Reference Figure 1-7 The present embodiment provides a leveling lifting device for a parking equipment trolley, comprising a power detection component 1, a flap 2, a leveling component 3, a support component 4, a transmission shaft 5 and a bearing 6; two groups of support components 4 are respectively located on the left and right sides of the leveling component 3, and the two ends of the opposite sides of the two groups of support components 4 are bolted to install bearings 6, and a transmission shaft 5 is installed between the two bearings 6 on each group of support components 4, and the transmission shaft 5 is connected to the flap 2 located above it through a key; the two ends of the support component 4 are connected to one end of the power detection component 1, and the flap 2 is hinged to the other end of the power detection component 1 through a pin shaft.

[0027] The power detection device 1 includes an electric push rod 101 with a stroke of 150 mm, on which an extended-in-place detection switch 102 and a return-in-place detection switch 103 are provided. The end of the electric push rod 101 is hingedly connected to a mounting seat 104, and the mounting seat 104 is fixedly connected to both ends of the supporting component 4.

[0028] The flap 2 includes a rotating sleeve 201 and a steel plate 202. The top of the rotating sleeve 201 is fixedly connected to the steel plate 202. The rotating sleeve 201 is provided with a connecting hole 203 that cooperates with the pin shaft.

[0029] The top surface of the leveling component 3 is a horizontal surface, and it is a component that needs to be leveled and protected for safety.

[0030] The support component 4 includes a frame 401 , a connecting steel 402 and a height adjustment bolt 403 . Two groups of connecting steels 402 are welded on one side of the frame 401 , and the height adjustment bolt 403 is installed on the connecting steel 402 .

[0031] The transmission shaft 5 is processed from a bar shaft, and the bearing 6 and the flap 2 can be installed on it. Matching fastening nuts are provided at both ends of the rotating shaft 5.

[0032] The bearing 6 is a self-aligning bearing. The rotation of the flap 2 drives the transmission shaft 5 to rotate around the self-aligning bearing. Two self-aligning bearings with seats are used as guide components, which not only ensures the coaxiality of the pin of the flap 2 and prevents jamming due to coaxiality error, but also ensures sufficient strength and saves costs.

[0033] The working principle of the present invention is: when the electric push rod 101 of the power detection component 1 is passed through a positive current, the electric push rod 101 retracts and recovers its stroke, so that the flap 2 drives the transmission shaft 5 to rotate around the axis of the two bearings 6, and at the same time, through the rotation of the transmission shaft 5, the rotational motion is transmitted to the flap 2 installed on the other side. When the electric push rod 101 retracts to a stroke of 150mm, the flap 2 rotates 45 degrees around the transmission shaft 5. During the rotation process, the bottom surfaces of the steel plates 202 of the two flaps 2 contact the tops of the height adjustment bolts 403 on the supporting component 4, generating an upward lifting force, lifting the leveling component 3 upward, completing the leveling, and realizing the overall lifting action process.

[0034] When the electric push rod 101 of the power detection component 1 is connected to a reverse current, the electric push rod 101 extends, and the steps are reversed as described above to realize the overall descending action process.

[0035] The above control and detection are all through the safety detection component 1 in the extended position detection switch 102 and the return position detection switch 103 to send signals to the PLC, through the PLC control forward and reverse contactor to achieve forward and reverse current control of the motor.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
