Description

Technical Field

[0001] The present invention relates to the technical field of running mechanisms, and particularly to an anti-derailment running mechanism. Background Art

[0002] With the development of industrial and engineering construction technologies, the application of rail-type running mechanisms has become increasingly widespread, and the industries and working conditions in which they are applied have also become more and more complex. Under some special working conditions, the running components will be subjected to irregular and large suspension forces, repulsive forces, etc. that offset their own gravity, resulting in up-and-down floating or left-and-right deviation, and even derailment, causing the equipment to be unusable or even safety accidents. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a running mechanism with a simple and reliable structure that can avoid derailment.

[0004] To solve the above technical problem, the present invention adopts the following technical solutions:

[0005] An anti-derailment running mechanism includes a running main body and a running guide rail. A sliding guide rail perpendicular to the running guide rail is provided on the running main body. A sliding seat is provided on the sliding guide rail. A pressing member and a driving member for driving the running main body to move along the running guide rail are provided on the sliding seat. The driving member and the pressing member are clamped on both sides of the running guide rail.

[0006] As a further improvement of the above technical solution: Clamping plates are provided on the sliding seat, and the sliding seat and the clamping plates are clamped on both sides of the sliding guide rail.

[0007] As a further improvement of the above technical solution: The driving member is a driving gear, and a transmission tooth meshing with the driving gear is provided on one side of the running guide rail close to the driving member.

[0008] As a further improvement of the above technical solution: The pressing member is a pressing roller.

[0009] As a further improvement of the above technical solution: The running main body is of a box structure.

[0010] As a further improvement of the above technical solution: An installation seat is provided on the sliding seat. The pressing member is slidably installed on the installation seat, and the sliding direction is perpendicular to the sliding guide rail and the running guide rail. A first positioning portion is provided on the running guide rail, and a second positioning portion is provided on the pressing member. The first positioning portion and the second positioning portion are in positioning cooperation.

[0011] As a further improvement of the above technical solution: The first positioning portion is a positioning groove, and the second positioning portion is a positioning flange.

[0012] Compared with the prior art, the advantages of the present invention are as follows: For the anti-derailment running mechanism disclosed by the present invention, a sliding seat is arranged on the running body, and the sliding seat can slide along a sliding guide rail arranged perpendicular to the running guide rail on the running body, so that the running body and the sliding seat are movably connected. A driving member and a pressing member are arranged on the sliding seat. The driving member and the pressing member clamp the running guide rail. During normal running, the driving member drives the sliding seat and the running body to move along the running guide rail. When the running body floats up and down or deflects left and right, the running body and the sliding seat move relative to each other, and the driving member and the pressing member on the sliding seat always hold the running guide rail tightly without separating from the running guide rail, so that the running body does not disengage from the running guide rail, and the structure is simple and reliable.

Detailed Description of the Invention

[0018] The present invention will be further described in detail below with reference to the accompanying drawings of the specification and specific embodiments.

[0019] Figures 1 to 3 An embodiment of the anti-derailment running mechanism of the present invention is shown. The anti-derailment running mechanism of this embodiment includes a running body 1 and a running guide rail 2. A sliding guide rail 3 arranged perpendicular to the running guide rail 2 is provided on the running body 1. A sliding seat 4 is provided on the sliding guide rail 3. A pressing member 6 and a driving member 5 for driving the running body 1 to move along the running guide rail 2 are provided on the sliding seat 4. The driving member 5 and the pressing member 6 are clamped on both sides of the running guide rail 2.

[0020] For this anti-derailment running mechanism, a sliding seat 4 is arranged on the running body 1. The sliding seat 4 can slide along a sliding guide rail 3 which is arranged perpendicular to the running guide rail 2 on the running body 1, so that the running body 1 and the sliding seat 4 are movably connected. A driving member 5 and a pressing member 6 are arranged on the sliding seat 4. The driving member 5 and the pressing member 6 clamp the running guide rail 2. During normal running, the driving member 5 drives the sliding seat 4 and the running body 1 to move along the running guide rail 2. When the running body 1 floats up and down or deflects left and right, the running body 1 and the sliding seat 4 move relative to each other, or in other words, the sliding seat 4 moves in the opposite direction of the floating and deflection of the running body 1. The driving member 5 and the pressing member 6 on the sliding seat 4 always hold the running guide rail 2 tightly and will not separate from the running guide rail 2, so that the running body 1 does not disengage from the running guide rail 2, and the structure is simple and reliable.

[0021] Further, in this embodiment, a clamping plate 41 is provided on the sliding seat 4, and the sliding seat 4 and the clamping plate 41 are clamped on both sides of the sliding guide rail 3. Specifically, as Figure 2 shown, the up-and-down sliding of the sliding seat 4 relative to the running body 1 is realized through the sliding seat 4 and the clamping plate 41, and at the same time, the relative movement of the sliding seat 4 and the running body 1 in the front-back direction and the left-right direction is restricted, and the structure is simple and reliable.

[0022] As a preferred technical solution, in this embodiment, the driving member 5 is a driving gear, and a transmission tooth 21 meshing with the driving gear is provided on one side of the running guide rail 2 close to the driving member 5. The use of a gear-rack pair for transmission has good reliability, avoids slipping, and has strong load-bearing capacity at the same time. Of course, in other embodiments, the driving member 5 can also be a driving roller, which is arranged above the running guide rail 2 and uses friction to realize the movement along the running guide rail 2, and can be used for working conditions with lighter loads; or a ball screw pair, a hydraulic cylinder, etc. can also be used between the driving member 5 and the running guide rail 2 to realize the movement of the driving member 5 along the running guide rail 2.

[0023] As a preferred technical solution, in this embodiment, the pressing member 6 is a pressing roller. While the pressing roller realizes the cooperation with the driving member 5 to hold the running guide rail 2 tightly, it can reduce the frictional resistance between the pressing roller and the running guide rail 2. Of course, in other embodiments, it can also be a pressing slider, etc.

[0024] As a preferred technical solution, in this embodiment, the running body 1 is of a box structure. The use of a box structure can arrange the power part (motor, reducer, etc.) of the driving member 5 in the box to reduce exposure.

[0025] Figure 4An embodiment of the anti-derailment running mechanism of the present invention is shown. The anti-derailment running mechanism of this embodiment is basically similar to that of the first embodiment, except that: in this embodiment, a mounting seat 7 is provided on the sliding seat 4, and the pressing member 6 is slidably mounted on the mounting seat 7, and the sliding direction is perpendicular to the sliding guide rail 3 and the running guide rail 2. A first positioning portion 22 is provided on the running guide rail 2, and a second positioning portion 61 is provided on the pressing member 6. The first positioning portion 22 and the second positioning portion 61 are in positioning cooperation. Figure 4 In it, the sliding guide rail 3 is arranged vertically, the running guide rail 2 is arranged in the direction perpendicular to the paper surface, and the pressing member 6 slides in the left-right direction. When the left-right distance between the running body 1, the sliding seat 4 and the driving member 5 as a whole and the running guide rail 2 changes ( Figure 4 a is a schematic structural diagram when the distance decreases, Figure 4 b is a schematic structural diagram of the normal distance, Figure 4 c is a schematic structural diagram when the distance increases), by using the positioning cooperation between the first positioning portion 22 and the second positioning portion 61, it is ensured that the pressing member 6 is always pressed against the running guide rail 2, and the running body 1, the sliding seat 4 and the driving member 5 as a whole slide relatively left and right with respect to the pressing member 6, and the structure is more reliable. As a preferred technical solution, when the pressing member 6 is a pressing roller, the mounting seat 7 can be a bushing, etc. The relative rotation between the wheel shaft of the pressing roller and the bushing is restricted by means of cooperation such as a clamping plate and a clamping groove, and the relative sliding along the axial direction is ensured.

[0026] Furthermore, in this embodiment, the first positioning portion 22 is a positioning groove, and the second positioning portion 61 is a positioning flange. The structure is simple and can reliably prevent the pressing member 6 from sliding left and right relative to the running guide rail 2.

[0027] Although the present invention has been disclosed above with preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible changes and modifications to the technical solution of the present invention, or modify it into an equivalent embodiment with equivalent changes, without departing from the scope of the technical solution of the present invention. Therefore, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall fall within the scope of the protection of the technical solution of the present invention.
