Description

Technical Field

[0001] The utility model belongs to the technical field of lifting components, and particularly relates to a running driving device for a rigid track. Background Art

[0002] As Figure 5 shown, it is a structural schematic diagram of an existing suspended sliding trolley. When in use, it can be installed at both ends of a crane main beam or an electric hoist, and can move on a U-shaped track with a U-shaped opening facing downwards as Figure 6 shown, so as to drive the main beam or the electric hoist to move. At present, when the suspended sliding trolley moves along the U-shaped track, it is usually driven by a driving device to move. Specifically, when in use, as Figure 7 shown, the traveling wheels of the existing driving device are located inside the U-shaped track and move on the inner bottom track surface of the U-shaped track. In the actual use process, in order to facilitate the installation of the traveling wheels of the driving device inside the U-shaped track, the wheel diameter of the traveling wheels of the driving device is smaller than the height inside the U-shaped track. In this way, after the driving device is installed on the U-shaped track, there will be a gap between the top of the traveling wheels of the driving device and the inner top surface of the U-shaped track. In this way, during the movement of the driving device, the traveling wheels sometimes slip, resulting in unstable operation of the driving device. Therefore, there are still drawbacks and deficiencies in the prior art. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a running driving device for a rigid track to solve the problems raised in the above background art.

[0004] The technical solution adopted by the utility model to solve the above problems:

[0005] A running driving device for a rigid track includes a vertically arranged support structure. The top of the support structure is rotatably connected with a driving wheel assembly with a horizontal axial line. The bottom of the support structure is provided with a driving mechanism that is in transmission connection with the driving wheel assembly. Two swing arms parallel to the support structure are installed on both sides of the support structure. The two swing arms are symmetrically arranged on both sides of the axial line of the driving wheel assembly. The top end of each swing arm is hinged to the top of the support structure, and the top of each swing arm is rotatably connected with a driven wheel assembly with the same traveling direction as the driving wheel assembly. An adjusting device capable of making the bottoms of the two swing arms approach or move away from each other is installed between the bottoms of the two swing arms. The top of the driving wheel assembly is higher than the top surface of the support structure. The driven wheel assemblies each include two driven wheels symmetrically arranged on both sides of the swing arm, and the traveling direction of the driven wheels is the same as that of the driving wheel assembly.

[0006] Furthermore, the adjusting device includes two relatively arranged adjusting blocks, which are respectively installed at the bottom positions of the two swing arms and are rotatably connected to the swing arms, and an adjusting screw is horizontally distributed and located outside the support structure. The two ends of the adjusting screw respectively pass through the two adjusting blocks and are slidably connected to the adjusting blocks, and a limit block is installed at one end of the adjusting screw, and the other end of the adjusting screw is sleeved and threadedly connected with an adjusting nut.

[0007] Furthermore, a spring is arranged between the adjusting block arranged close to the adjusting nut and the adjusting nut, and the spring is slidably sleeved on the adjusting screw.

[0008] Furthermore, hinge shafts parallel to the axial line of the driving wheel assembly are installed on both sides of the support structure, and the top ends of the swing arms are slidably mounted on the hinge shafts and hinged to the support structure through the hinge shafts; a sleeve is slidably mounted on the adjusting screw between the two adjusting blocks.

[0009] Furthermore, the driving wheel assembly includes two driving wheel axles that are horizontally arranged opposite to each other and located at the same height, the driving wheel axles are both rotatably connected to the support structure, and the two driving wheel axles are commonly connected by the driving mechanism, and both ends of the driving wheel axles are provided with driving wheels after passing through the support structure, and the top of the driving wheel is higher than the top surface of the support structure.

[0010] Furthermore, the driving mechanism includes a reducer installed on the support structure, the reducer is transmission-connected to the driving motor, and the output shaft of the reducer is parallel to the driving wheel shaft and is fitted with a driving sprocket, the driving wheel shaft is fitted with a driven sprocket opposite to the driving sprocket, and an annular chain is installed between the two driven sprockets and the driving sprocket.

[0011] Furthermore, the driven wheel assembly also includes a driven wheel shaft arranged parallel to the driving wheel shaft, the driven wheel shaft is rotatably connected to the swing arm respectively, and the two ends of the driven wheel shaft are both mounted with the driven wheels after passing through the swing arm.

[0012] Furthermore, the outer side of at least one swing arm is detachably connected to a traction bracket via a bolt connection pair.

[0013] By adopting the above technical solution, the beneficial effects of the utility model are:

[0014] In the initial state of the present utility model, the height difference between the top of the driving wheel assembly and the bottom of the driven wheel is less than the height within the U-shaped track. In this way, during use, after connecting the driving device to the suspended sliding trolley, it is convenient to install the driving device and the suspended sliding trolley together on the U-shaped track from one end of the U-shaped track. During the installation process, the top of the swing arm and the top of the support structure can both penetrate through the U-shaped track through the U-shaped opening of the U-shaped track, and both the driving wheel assembly and the driven wheel assembly can be located within the U-shaped track, while the adjusting device is located outside the U-shaped track. At this time, since the driven wheels are located on both sides of the swing arm, after installing the driving device, the bottoms of the driven wheels can respectively abut against the inner bottom track surface of the U-shaped track. Then, through the adjusting device, the bottoms of the two swing arms can be made to approach each other. During the process of the bottoms of the two swing arms approaching each other, the height difference between the bottom of the driven wheel and the top of the driving wheel assembly can be increased, so that the top of the driving wheel assembly abuts against the inner top track surface of the U-shaped track, and the bottoms of the driven wheels respectively abut against the inner bottom track surface of the U-shaped track. In this way, when the driving device moves driven by the driving mechanism, the driven wheels can move along the inner bottom track surface of the U-shaped track, and the driving wheel assembly can move along the inner top track surface of the U-shaped track, thereby improving the stability of the driving device during operation and reducing the occurrence of slipping.

Detailed implementation mode

[0023] To make the objectives, technical solutions and beneficial effects of the present utility model clearer, the following further describes in detail the implementation modes of the present utility model with reference to the accompanying drawings.

[0024] As Figures 1 to 4 shown, the present utility model provides a running driving device for a rigid track, which can move on a U-shaped track 11 as Figure 6 shown; the inner bottom surface of the U-shaped track 11 is the inner bottom track surface 111, the inner top surface of the U-shaped track 11 is the inner top track surface 112, and the height inside the U-shaped track 11 is the vertical distance between the inner bottom track surface 111 and the inner top track surface 112; the present utility model includes a vertically arranged support structure 5, the top of the support structure 5 is rotatably connected with a driving wheel assembly 3 with a horizontal axial line, the bottom of the support structure 5 is provided with a driving mechanism 6 that is in transmission connection with the driving wheel assembly 3, and two swing arms 1 parallel to the support structure 5 are installed outside the two sides of the support structure 5, and the two swing arms 1 are symmetrically arranged on both sides of the axial line of the driving wheel assembly 3. Specifically, taking Figure 1 as an example, the swing arms 1 are located on the left and right sides of the support structure 5, and the swing arms 1 can be set as arc-shaped arms with the arc opening facing inwards; in addition, the thicknesses of the swing arms 1 and the support structure 5 are both smaller than the width of the U-shaped opening of the U-shaped track 11, so that after the driving device is installed on the U-shaped track 11, the tops of the swing arms 1 and the top of the support structure 5 can both pass through the U-shaped track 11 through the U-shaped opening of the U-shaped track 11.

[0025] The top end of each swing arm 1 is hinged to the top of the support structure 5, and a driven wheel assembly 4 with the same traveling direction as the driving wheel assembly 3 is rotatably connected to the top of each swing arm 1. An adjusting device 2 capable of making the bottoms of the two swing arms 1 approach or move away from each other is installed between the bottoms of the two swing arms 1, that is, the two swing arms 1 can swing around the axial line of the driving wheel assembly 3; the top of the driving wheel assembly 3 is higher than the top surface of the support structure 5, so that when in use, the support structure 5 can be prevented from touching the inner top track surface 112; each driven wheel assembly 4 includes two driven wheels 41 symmetrically arranged on both sides of the swing arm 1, and the traveling direction of the driven wheels 41 is the same as that of the driving wheel assembly 3.

[0026] Specifically, in the initial state, the height difference between the top of the driving wheel assembly 3 and the bottom of the driven wheel 41 is less than the height inside the U-shaped track 11. So when in use, after connecting the driving device to the suspended sliding trolley 10, it is convenient to install the driving device and the suspended sliding trolley 10 together on the U-shaped track 11 from one end of the U-shaped track 11. During the installation process, the top of the swing arm 1 and the top of the support structure 5 can pass through the U-shaped track 11 through the U-shaped opening of the U-shaped track 11, and the driving wheel assembly 3 and the driven wheel assembly 4 can be located inside the U-shaped track 11, while the adjusting device 2 is located outside the U-shaped track 11. At this time, since the driven wheels 41 are located on both sides of the swing arm 1, after installing the driving device, the bottoms of the driven wheels 41 can be made to abut against the inner bottom track surface of the U-shaped track 11 respectively, and then the bottoms of the two swing arms 1 can be made to approach each other through the adjusting device 2. During the process of the bottoms of the two swing arms 1 approaching each other, the height difference between the bottom of the driven wheel 41 and the top of the driving wheel assembly 3 can be increased, so that the top of the driving wheel assembly 3 abuts against the inner top track surface 112 of the U-shaped track 11, and the bottoms of the driven wheels 41 abut against the inner bottom track surface 111 of the U-shaped track 11 respectively. In this way, when the driving device moves driven by the driving mechanism 6, the driven wheels 41 can move along the inner bottom track surface 111 of the U-shaped track 11, and the driving wheel assembly 3 can move along the inner top track surface 112 of the U-shaped track 11, thereby improving the stability of the driving device during operation and reducing the occurrence of slipping.

[0027] The specific setting method of the adjusting device 2 is as follows: As Figures 1 to 4As shown, the adjusting device 2 includes two relatively arranged adjusting blocks 21, and the axial lines of the adjusting blocks 21 are parallel to the axial line of the driven wheel 41; the two adjusting blocks 21 are respectively installed at the bottom positions of the two swing arms 1 and are rotatably connected to the swing arms 1, and an adjusting screw 22 horizontally distributed outside the bracket structure 5 is arranged between the two adjusting blocks 21. The two ends of the adjusting screw 22 respectively penetrate through the two adjusting blocks 21 and are slidably connected to the adjusting blocks 21, and a limiting block 23 is installed at one end of the adjusting screw 22, and an adjusting nut 24 is sleeved and threadedly connected to the other end of the adjusting screw 22. Specifically, in use, after the driving device and the hanging trolley 10 are jointly installed on the U-shaped track 11, the adjusting device 2 is located outside the U-shaped track 11. Then, by rotating the adjusting nut 24 on the adjusting screw 22, the bottoms of the two swing arms 1 can be made to approach each other along the adjusting screw 22 to increase the height difference between the bottom of the driven wheel 41 and the top of the driving wheel assembly 3; and by rotating the adjusting nut 24 in the reverse direction, the bottoms of the two swing arms 1 can be manually made to move away from each other along the adjusting screw 22.

[0028] Further, as Figures 1 to 4 shown, a spring 25 is arranged between the adjusting block 21 close to the adjusting nut 24 and the adjusting nut 24. The spring 25 is slidably sleeved on the adjusting screw 22. At this time, when the bottoms of the two swing arms 1 are made to approach each other along the adjusting screw 22, the spring 25 can be compressed by rotating the adjusting nut 24, and the spring 25 can push the swing arms 1 to make the bottoms of the two swing arms 1 approach each other along the adjusting screw 22 to adjust the bottoms of the driven wheels 41 and the tops of the driving wheel assemblies 3 to appropriate positions; and by arranging the spring 25, when the driving device is running, if the phenomenon of wheel jamming occurs, the driven wheel assembly 4 can play a tensioning role by compressing the spring 25 through the swing arms 1 to reduce the occurrence of the wheel jamming phenomenon.

[0029] Further, as Figure 1 、 Figure 3 and Figure 4 shown, hinge shafts parallel to the axial line of the driving wheel assembly 3 are installed inside both sides of the bracket structure 5, and the hinge shafts are not shown in the figure; the tops of the swing arms 1 are respectively slidably sleeved on the hinge shafts and are hinged to the bracket structure 5 through the hinge shafts. Specifically, in use, the two swing arms 1 can swing around the hinge shafts respectively; in addition, since the tops of the swing arms 1 are respectively slidably sleeved on the hinge shafts, the swing arms 1 sometimes move axially along the hinge shafts, thus as Figure 1 shown, the adjusting screw 22 will touch the bracket structure 5 and affect the use. Therefore, a sleeve 26 is slidably sleeved on the adjusting screw 22 between the two adjusting blocks 21. Specifically, by arranging the sleeve 26, the adjusting screw 22 can be prevented from touching the bracket structure 5 for convenient use.

[0030] Further, the specific setting method of the bracket structure 5 is as follows: AsFigures 1 to 3 As shown, the support structure 5 includes two vertically opposed and spaced columns 51, an inverted U-shaped plate 52 with a U-shaped opening facing downward is installed between the top ends of the two columns 51 through a bolt connection pair 8, and a vertically distributed fixed shell 53 with an opening on the top is installed between the bottom ends of the two columns 51 through a bolt connection pair 8.

[0031] The specific configuration of the driving wheel assembly 3 is as follows: Figures 1 to 3 As shown, the driving wheel assembly 3 includes two driving wheel shafts 31 which are horizontally arranged opposite to each other and located at the same height. The driving wheel shafts 31 are both rotatably connected to the support structure 5, and the two driving wheel shafts 31 are commonly connected by transmission with the driving mechanism 6. Both ends of the driving wheel shaft 31 pass through the support structure 5 and are also fitted with driving wheels 32, that is, there are four driving wheels 32; the tops of the driving wheels 32 are all higher than the top surface of the support structure 5. Specifically, the two ends of the driving wheel shaft 31 are respectively rotatably connected to the two side plates of the inverted U-shaped plate 52, and both ends of the driving wheel shaft 31 pass through the inverted U-shaped plate 52 and are also fitted with driving wheels 32, and the tops of the driving wheels 32 are higher than the top surface of the inverted U-shaped plate 52; in addition, the two hinge shafts are respectively located on both sides of the inverted U-shaped plate 52.

[0032] The specific configuration of the driving mechanism 6 is as follows: Figures 1 to 4 As shown, the driving mechanism 6 includes a reducer 61 installed on the support structure 5, and the reducer 61 is connected to the driving motor 62, and the output shaft of the reducer 61 is parallel to the driving wheel shaft 31 and is set with a driving sprocket. Specifically, the output shaft of the driving motor 62 is vertically distributed and is connected to the output shaft of the reducer 61 through a bevel gear transmission structure. Figure 1 For example, the overall width of the driving device in the front-to-back direction can be reduced; the driving wheel shaft 31 is equipped with a driven sprocket opposite to the driving sprocket, and an annular chain 9 is installed between the two driven sprockets and the driving sprocket. Specifically, the reducer 61 is installed on the side of the fixed shell 53 away from the adjusting device 2, and the output shaft of the reducer 61 passes through the fixed shell 53 and is located in the fixed shell 53. The output shaft of the reducer 61 located in the fixed shell 53 is equipped with a driving sprocket, and the driving wheel shaft 31 located in the inverted U-shaped plate 52 is equipped with a driven sprocket, and an annular chain 9 is installed between the two driven sprockets and the driving sprocket. The driven sprocket and the driving sprocket are not shown in the figure. When in use, when the driving mechanism 6 is started, the driving wheel 32 can be driven to rotate.

[0033] The specific configuration of the driven wheel 41 is as follows: Figures 1 to 3 As shown, the driven wheel assembly 4 also includes a driven wheel shaft 42 arranged parallel to the driving wheel shaft 31. The driven wheel shaft 42 is rotatably connected to the swing arm 1 respectively, and both ends of the driven wheel shaft 42 are fitted with the driven wheels 41 after passing through the swing arm 1, that is, there are four driven wheels 41.

[0034] Furthermore, as Figures 1 to 4 shown, a traction bracket 7 is detachably connected to the outer side of at least one swing arm 1 through a bolt connection pair 8. Specifically, the traction bracket 7 can be set as a Z-shaped bracket. During assembly, the driving device can be connected to the suspension trolley 10 through the traction bracket 7; during use, the top of the traction bracket 7 can penetrate through the U-shaped opening of the U-shaped track 11 and be slidably connected to the U-shaped track 11.
