Detailed Description
In order to describe the technical contents, the achieved objects and effects of the present utility model in detail, the following description will be made with reference to the embodiments in conjunction with the accompanying drawings.
Referring to fig. 1, a walking device of a single-track trolley comprises a walking wheel 6 movably mounted on a transmission shaft 7, and compensation structures arranged on the transmission shaft 7 and respectively positioned at two sides of the walking wheel 6; the compensation structure comprises a movable sleeve 5 and a fixed sleeve 3; wherein the movable sleeve 5 is arranged on one side of the transmission shaft 7 close to the travelling wheel 6, and the fixed sleeve 3 is arranged on one side of the transmission shaft 7 far away from the travelling wheel 6; a gap is formed between the fixed sleeve 3 and the movable sleeve 5 in the axial direction, and the fixed sleeve 3 and the movable sleeve 5 are axially connected through an elastic piece.
Wherein the running gear is loaded in the single track trolley to realize the movement of the single track trolley on the track 1 through the connection track 1. The walking device overcomes the problem of unsmooth clamping stagnation of the trolley when the trolley is excessively bent (such as the excessive bending radius is 1 m) through the compensation structures which are arranged on the two sides of the walking wheel 6 and positioned on the transmission shaft 7.
In particular, the compensating structure comprises a movable sleeve 5 and a fixed sleeve 3. Wherein the movable sleeve 5 is movably connected with the transmission shaft 7, i.e. the movable sleeve 5 is allowed to move on the transmission shaft 7, and because the travelling wheel 6 is movably mounted on the transmission shaft 7, i.e. the travelling wheel 6 is also allowed to move along the axial direction of the transmission shaft 7, the movable sleeve 5 is preferably moved along with the travelling wheel 6 in order to avoid undesired interference of the two. In this embodiment, since the fixed sleeve 3 is fixed relative to the drive shaft 7, that is, no relative movement of the fixed sleeve 3 and the drive shaft 7 occurs, when the fixed sleeve 3 and the movable sleeve 5 are installed with an axial gap therebetween and are connected by an elastic member, the gap formed between the movable sleeve 5 and the fixed sleeve 3 in the axial direction allows the travel wheel 6 to be axially offset within a certain range, that is, in this embodiment, the axial offset of the travel wheel 6 is defined by the axial gap between the movable sleeve 5 and the fixed sleeve 3. Because the compensation structure endows the walking wheel 6 with a certain degree of axial offset capability, when the walking wheel 6 turns, the compensation structure allows the walking wheel 6 to offset in the direction consistent with the turning direction, so that the direction of the walking wheel is automatically adjusted, and the problems of the over-finished clamping stagnation and unsmooth trolley are solved. That is, in this embodiment, the axial direction of the travelling wheel 6 is the normal direction of the curved surface of the curved section of the track 1.
The compensation structures are arranged on both sides of the travelling wheel 6, so that the travelling wheel 6 can be kept balanced and centered by using two compensation structures when the single-track trolley runs in a straight line. Specifically, the elastic member is installed between the fixed sleeve 3 and the movable sleeve 5 in a manner of having a certain pretightening force, so that both ends of the elastic member can be kept to be pressed on the movable sleeve 5 and the fixed sleeve 3 all the time, and the reset of the movable sleeve 5 and the fixed sleeve 3 can be realized by utilizing the elasticity of the elastic member, namely the axial clearance is formed, and the balance centering of the travelling wheel 6 in the straight running process is kept. In this embodiment, in order to facilitate the installation of the elastic member, the movable sleeve 5 and the fixed sleeve 3 each adopt a basin-type sleeve structure. In an alternative embodiment, the elastic member is a spring 4.
In one embodiment, in order to achieve a synchronous movement between the road wheel 6 and the movable sleeve 5, it is preferred that the movable sleeve 5 is mounted on the road wheel 6. In an alternative embodiment, the travelling wheel 6 is a cylindrical grooved wheel, the two axial ends of which are respectively provided with a countersink, and at least part of the movable sleeve 5 is embedded in the countersink for connection and synchronous movement of the two.
A single-track trolley comprises a track 1 and the travelling device; wherein the travelling wheel 6 is mounted on the track 1.
In one embodiment, the diameter of the two axial ends of the travelling wheel 6 is larger than that of the middle part of the travelling wheel 6, and the width a of the middle part of the travelling wheel 6 is slightly larger than that b of the track 1, namely in this embodiment, the travelling wheel 6 with the width a of the middle part slightly larger than that b of the track 1 is used, so that the travelling wheel 6 is mounted on the track 1, and friction noise caused by excessive contact during relative movement of the travelling wheel 6 and the track 1 is avoided.
In an alternative embodiment, the track 1 is rectangular in cross-section.
In one embodiment, the single track trolley further comprises a frame 2, the frame 2 is connected with the track 1 through at least one running gear, and the fixing sleeve 3 is fixedly installed on the frame 2. In this embodiment, the fixing sleeve 3 may be mounted on the frame 2 in any manner, so long as a stable and safe connection between the two is maintained. The number of running gear in the frame 2 may be chosen according to the actual need, as two are shown in fig. 1.

the section of the track 1 is rectangular; the frame 2 is connected with the track 1 through at least one running gear, and the fixed sleeve 3 is fixedly arranged on the frame 2.
In particular, when the monorail trolley moves on the linear rail 1, it is limited by the spring 4 to keep the balance of the road wheels 6 centered on the rail 1. When the single-track trolley turns, the walking wheel 6 is allowed to displace to a certain extent along the direction consistent with the turning direction by the action of the compensation structure, so that the direction of the single-track trolley is automatically adjusted conveniently, and the problems of the trolley that the trolley is jammed and unsmooth in the turning process are solved.
