Description

Technical Field

[0001] The invention relates to the technical field of intelligent conveying systems, and in particular to an adaptive aerial double-track trolley. Background Art

[0002] The double-track trolley is a traction trolley commonly used in intelligent conveying equipment. It is the power device for the conveying equipment to move, and it uses friction drive to independently run on the conveying track. With the development of the intelligent conveying industry and the diversified requirements of production workshops, the conveying lines of double-track trolleys are becoming increasingly complex, especially the application of curved tracks. The radius and arc length of the inner and outer curved sections of the track are different, and the relative position between the trolley groups changes in real time, which puts higher requirements on the double-track trolley.

[0003] There are many different methods used by existing double-track trolleys to solve the problem of turning, but each has its own problems. For example, some double-track trolleys have added an independent track-changing mechanism to complete the turn, so the time to complete the turn is usually very long; some double-track trolleys use two sets of motors to drive the trolleys on the two tracks respectively, so it is necessary to configure two independent motors and control and coordinate the two motors separately, which not only increases the cost but also increases the difficulty of electrical control; some trolleys use universal wheels, but this will cause the front and rear wheels to travel different paths, which will greatly increase the difficulty of track design.

[0004] Generally speaking, the problem that a double-track trolley needs to overcome when turning is how to ensure smooth passage through the curve. Because the turning radius of the inner and outer tracks is different, the wheel speeds of the inner and outer tracks are different, and the positional relationship between the front and rear wheel beams of the inner and outer tracks will constantly change. Therefore, the invention of a new type of double-track trolley is particularly necessary. Summary of the invention

[0005] 1. Technical issues to be resolved

[0006] The purpose of the present invention is to provide an adaptive aerial double-track trolley to solve the defects of the existing aerial double-track trolley, such as complex structure, high cost and slow turning speed. (II) Summary of the invention

[0008] In order to solve the above technical problems, the present invention provides an adaptive aerial double-track trolley, comprising: a main car and three auxiliary cars, the three auxiliary cars are respectively a first auxiliary car, a second auxiliary car and a third auxiliary car, and also comprising two first tracks and a second track arranged in parallel with each other, the main car and the first auxiliary car are installed on the first track, and the second auxiliary car and the second auxiliary car are installed on the second track; also comprising a driving motor, the driving motor drives the main car to move horizontally along the first track; a bearing member is arranged below the first track and the second track; also comprising four sets of lifting devices, the main car and the third auxiliary car arranged opposite to the main car are directly connected to the bearing member through the lifting devices, the second auxiliary car and the fourth auxiliary car are respectively connected to the bearing beam connecting rod, and are connected to the bearing member through the bearing beam connecting rod; the bearing member and the first track and the second track are arranged in parallel with each other; the bearing beam connecting rod is hinged to the bearing member.

[0009] Furthermore, the lifting device includes a pulley block, a lifting plate and a fixed plate. The pulley block is clamped on the first track or the second track. The lifting plate is vertically arranged with the pulley block. The bottom of the lifting plate is provided with a fixed plate extending outward, and the fixed plate is a detachable connecting bearing member.

[0010] Furthermore, the bearing member is configured as a rectangular frame structure, the bearing member is configured below the first track and the second track, the main vehicle and the third auxiliary vehicle fix two opposite corners of the bearing member through a hoisting member, and the second auxiliary vehicle and the fourth auxiliary vehicle are connected to the other two corners of the bearing member through a bearing beam connecting rod.

[0011] Furthermore, the load-bearing beam connecting rod includes a connecting rod body, one end of which is provided with a threaded hole, and the other end is two positioning plates arranged opposite to each other. The tail ends of the two positioning plates are provided with through holes, and the double-headed screw passes through the through holes to fix the two positioning plates.

[0012] Furthermore, the first track and the second track are I-shaped steel tracks.

[0013] (III) Beneficial effects

[0014] The adaptive aerial double-track trolley provided by the present invention comprises: a main car and three auxiliary cars, wherein the three auxiliary cars are respectively a first auxiliary car, a second auxiliary car and a third auxiliary car, and further comprises two first tracks and a second track arranged in parallel with each other, wherein the main car and the first auxiliary car are mounted on the first track, and the second auxiliary car and the second auxiliary car are mounted on the second track; further comprises a driving motor, wherein the driving motor drives the main car to move horizontally along the first track; bearing members are arranged below the first track and the second track; further comprises four sets of hoisting devices, wherein the main car and the third auxiliary car arranged opposite to the main car are directly connected to the bearing members through the hoisting devices, and the second auxiliary car and the fourth auxiliary car are respectively connected to the bearing beam connecting rod, and are connected to the bearing beam connecting rod through the lifting device. The load-bearing beam connecting rod connects the load-bearing member; the load-bearing member is arranged parallel to the first track and the second track; since the main car and the third auxiliary car are directly connected to the load-bearing member through the lifting device, the distance between the two parts remains unchanged, and the second auxiliary car and the fourth auxiliary car are connected to the load-bearing member through the load-bearing beam connecting rod, and the load-bearing beam connecting rod and the load-bearing member are hinged, so when the car turns, the second auxiliary car and the fourth auxiliary car can adjust themselves according to the change of the track, so as to achieve fast turning; at the same time, when the turning radius or track gauge is larger than the adaptive adjustment distance, the double track with various spacings or turning radii can be achieved by changing the length of the load-bearing beam connecting rod, which is more versatile.
