Description

Technical Field

[0001] The present application relates to the technical field of slide rail trolleys, and in particular to a slide rail trolley with a track cleaner. Background Art

[0002] The rail car, also known as rail flat car, electric flatbed car, rail flat car, rail flatbed car, flat car, trolley, cross-car, ground crawler, etc., is a commonly used rail electric transport vehicle in production and manufacturing. First of all, it is an electric vehicle that runs automatically under electric drive. Secondly, it is a vehicle running on rails, and tracks need to be laid on the ground. The car body has no direction control device and can only move forward and backward (even turning depends on the track). The rail car has the characteristics of simple structure, easy use, large carrying capacity, easy maintenance, and long service life. Due to its convenience, sturdiness, economy, practicality, and easy cleaning, it has become the preferred transportation tool for frequent short-distance fixed-point transportation of heavy objects within the factory buildings of enterprises and between factories.

[0003] With regard to the above-mentioned related technologies, the inventors believe that the following defects exist: in daily use, foreign impurities such as dirt, dust or fine stones are easily accumulated on the guide rails. When the slide trolley passes over the guide rails where foreign objects exist, the foreign objects on the guide rails come into contact with the pulleys on the slide trolley, which at the very least reduces the smoothness of the slide of the slide trolley, and at worst causes the pulleys on the slide trolley to collide and wear, so further improvements are needed.

In this embodiment, the vehicle plate 1 is a rectangular plate, and the length direction of the vehicle plate 1 is parallel to the length direction of the guide rail. The lower end surfaces on both sides of the vehicle plate 1 are fixedly connected with mounting plates 11, and the mounting plates 11 are rotatably connected with a pair of horizontally arranged mounting shafts 12. The two mounting shafts 12 are distributed along the length direction of the vehicle plate 1, and the axial direction of the mounting shafts 12 is parallel to the width direction of the vehicle plate 1. Both ends of the mounting shafts 12 are coaxially fixedly connected with running wheels 13 for running on the guide rail, and the vehicle plate 1 is provided with a driving power device 2 for driving one of the mounting shafts 12 to rotate.

[0048] The driving power device 2 includes a reducer 21 and a drive motor 22 fixedly connected to the lower end surface of the vehicle plate 1.

The vehicle plate 1 is provided with multiple groups of guide rail cleaners. In this embodiment, four groups of guide rail cleaners are provided and are arranged one by one with the running wheels 13. The guide rail cleaners are located on the outside of the running wheels 13.

[0049] Reference Figure 3 , Figure 4 The lower end surface of the vehicle plate 1 is fixedly connected with a mounting frame 14, and the mounting frame 14 is fixedly penetrated with a guide cylinder 141, and the guide cylinder 141 is arranged vertically. The number of mounting frames 14 corresponds to the number of guide rail cleaners. Each set of guide rail cleaners includes a cleaning shaft body 3 that is coaxially rotatable and penetrated through the guide cylinder 141, a cleaning member that is arranged on the cleaning shaft body 3 and abuts against the guide rail to clean foreign objects on the guide rail, and a driving mechanism 5 for driving the cleaning shaft body 3 to rotate. The cleaning shaft body 3 includes a first cleaning shaft 31 that is coaxially rotatable and penetrated through the guide cylinder 141, a connecting sleeve 32 that is coaxially fixedly sleeved at the lower part of the first cleaning shaft 31, and a second cleaning shaft 33 that is inserted at the lower part of the connecting sleeve 32. In this embodiment, the connecting sleeve 32 is located below the guide cylinder 141, and the connecting sleeve 32 is an insulating sleeve. There is a gap between the lower end surface of the first cleaning shaft 31 and the upper end surface of the second cleaning shaft 33 to improve the anti-conductive performance of the guide rail cleaner. The second cleaning shaft 33 is fixedly inserted in the connecting sleeve 32. The cleaning member is a cleaning disc 4 coaxially fixedly sleeved on the lower part of the second cleaning shaft 33 , and a flexible bristle 41 is protruding and fixed on the lower end surface of the cleaning disc 4 , and the bristle 41 abuts against the upper end surface of the guide rail.

[0050] Reference Figure 3 , Figure 4 , Figure 5 The driving mechanism 5 is located between the cleaning shaft body 3 and the mounting shaft 12. The driving mechanism 5 includes a first transmission shaft 51 rotatably connected to the vehicle plate 1, a second transmission shaft 52 rotatably connected to the mounting frame 14, a first transmission assembly 53 arranged between the first transmission shaft 51 and the second transmission shaft 52 so that the first transmission shaft 51 and the second transmission shaft 52 rotate synchronously, a second transmission assembly 54 arranged between the second transmission shaft 52 and the cleaning shaft body 3 so that the second transmission shaft 52 and the cleaning shaft body 3 rotate synchronously, and a linkage member. The first transmission shaft 51 and the second transmission shaft 52 are horizontally arranged and located above the cleaning shaft body 3. The linkage member is arranged between the first transmission shaft 51 and the mounting shaft 12 or between the first transmission shaft 51 and the walking wheel 13.

[0051] In this embodiment, the lower end surface of the vehicle plate 1 is provided with a connecting arm 15 located between the mounting frame 14 and the mounting shaft 12, and the lower part of the connecting arm 15 is fixedly connected with a mounting seat 16, and the mounting seat 16 has a mounting cavity, and a side of the mounting seat 16 close to the inner end surface of the running wheel 13 is penetrated by a avoidance groove connected to the mounting cavity. The axial direction of the first transmission shaft 51 is perpendicular to the axial direction of the mounting shaft 12, and the axial direction of the second transmission shaft 52 is parallel to the axial direction of the mounting shaft 12. The axis of the first transmission shaft 51, the axis of the second transmission shaft 52 and the axis of the mounting shaft 12 are located at the same horizontal height. One end of the first transmission shaft 51 is rotatably connected to the mounting frame 14 and the other end is rotatably passed through the mounting seat 16. The linkage part includes a first linkage wheel 55 built into the first transmission shaft 51. The first linkage wheel 55 is a polyurethane wheel. One side outer peripheral wall of the first linkage wheel 55 passes through the avoidance groove and abuts against the inner end face of the running wheel 13. The middle position of the outer peripheral wall of the first linkage wheel 55 abuts against the edge of the end face of the running wheel 13. The rotation of the running wheel 13 drives the first linkage wheel 55 to rotate through friction.

[0052] The first transmission assembly 53 includes a first bevel gear 531 coaxially fixedly sleeved on the first transmission shaft 51 and a second bevel gear 532 coaxially fixedly sleeved on the second transmission shaft 52, and the first bevel gear 531 is externally meshed with the second bevel gear 532. The second transmission assembly 54 includes a third bevel gear 541 coaxially fixedly sleeved on the second transmission shaft 52 and a fourth bevel gear 542 coaxially fixedly sleeved on the first cleaning shaft 31, and the third bevel gear 541 is externally meshed with the fourth bevel gear 542.

[0053] The implementation principle of a slide rail trolley with a track cleaner in Example 1 is as follows: the slide rail trolley moves on the guide rail under the drive of the traveling power device 2. During the movement of the slide rail trolley, the walking wheel 13 rotates and drives the first linkage wheel 55 to rotate around its own axis through the friction force of the end surface, thereby realizing the rotation of the first transmission shaft 51. The first transmission shaft 51 drives the second transmission shaft 52 to rotate through the first bevel gear 531 and the second bevel gear 532. The second transmission shaft 52 drives the cleaning shaft 3 to rotate through the third bevel gear 541 and the fourth bevel gear 542, thereby driving the cleaning disc 4 to rotate to clean different positions of the upper end surface of the guide rail, thereby sweeping away foreign matter accumulated on the upper end surface of the guide rail, making the surface of the guide rail smoother, effectively reducing the possibility of contact between the walking wheel 13 and foreign matter, and improving the smoothness of the sliding of the slide rail trolley.

[0054] Embodiment 2: This embodiment differs from Embodiment 1 in that, referring to Figure 6 , Figure 7The lower end surface of the vehicle plate 1 is slidably connected with a sliding block 151 along the width direction, and the connecting arm 15 is fixedly connected to the sliding block 151. The trolley is provided with an adjustment assembly 6 for adjusting the sliding position of the sliding block 151, and the adjustment assembly 6 includes an adjustment plate 61 fixedly connected to the lower end surface of the vehicle plate 1, an adjustment screw 62 rotatably connected to the adjustment plate 61, and an adjustment wheel 63 fixedly sleeved on the adjustment plate 61, the axial direction of the adjustment screw 62 is parallel to the width direction of the vehicle plate 1, and the adjustment screw 62 is threadedly penetrated through the sliding block 151.

[0055] The first transmission shaft 51 includes a first connecting shaft 511, a second connecting shaft 512 and a universal coupling 513 arranged between the first connecting shaft 511 and the second connecting shaft 512. The first connecting shaft 511 is rotatably connected to the mounting frame 14, the second connecting shaft 512 is rotatably connected to the mounting seat 16, the first linkage wheel 55 is coaxially fixedly sleeved on the second connecting shaft 512, and the first bevel gear 531 is coaxially fixedly sleeved on the first connecting shaft 511. Specifically, the universal coupling 513 is a telescopic universal coupling 513.

[0056] The implementation principle of a slide trolley with a track cleaner in Example 2 is as follows: when the slide trolley is moving, the walking wheel 13 rotates and drives the first interlocking wheel 55 to rotate around its own axis through the friction force of the end surface, thereby realizing the rotation of the first connecting shaft 511, and driving the second connecting shaft 512 to rotate through the universal joint 513, driving the second transmission shaft 52 to rotate through the first bevel gear 531 and the second bevel gear 532, and the second transmission shaft 52 drives the cleaning shaft 3 to rotate through the third bevel gear 541 and the fourth bevel gear 542, thereby driving the cleaning disc 4 to rotate to clean different positions of the upper end surface of the guide rail, thereby sweeping away foreign matter accumulated on the upper end surface of the guide rail, making the surface of the guide rail smoother, effectively reducing the possibility of contact between the walking wheel 13 and foreign matter, and improving the smoothness of the sliding of the slide trolley.

[0057] By rotating the adjusting screw to adjust the sliding position of the mounting seat 16, the first interlocking wheel 55 is always pressed against the end face of the walking wheel 13, thereby reducing the possibility that the first interlocking wheel 55 will not rotate due to wear of the outer peripheral wall of the first interlocking wheel 55. The first connecting shaft 511 and the second connecting shaft 512 are connected by a telescopic universal coupling 513. The length of the telescopic universal coupling 513 is correspondingly extended and retracted according to the position of the first connecting shaft 511, thereby ensuring normal transmission of the first connecting shaft 511 and the second connecting shaft 512.

[0058] Embodiment 3: This embodiment differs from Embodiment 1 in that, referring to Figure 8 , Fig. 9The axial direction of the first transmission shaft 51 is parallel to the axial direction of the installation shaft 12, and the axial direction of the second transmission shaft 52 is perpendicular to the axial direction of the first transmission shaft 51. The linkage member includes a second linkage wheel 56 coaxially fixedly sleeved on the first transmission shaft 51, and the outer peripheral wall of the second linkage wheel 56 abuts against the outer peripheral wall of the running wheel 13. When the running wheel 13 rotates, the second linkage wheel 56 is driven to rotate around its own axis. The first transmission shaft 51 is coaxially fixedly connected with a first gear 514, and the installation shaft 12 is fixedly sleeved with a second gear 121. The first gear 514 is externally meshed with the second gear 121, which reduces the possibility of the second linkage wheel 56 slipping and increases the stability of the transmission.

[0059] The implementation principle of a slide rail trolley with a track cleaner in Example 3 is as follows: when the walking wheel 13 rotates around its own axis, the second interlocking wheel 56 is driven to rotate around its own axis through friction, and the rotation stability of the first transmission shaft 51 is improved through the cooperation of the first gear 514 and the second gear 121. The first transmission shaft 51 drives the second transmission shaft 52 to rotate through the first bevel gear 531 and the second bevel gear 532, and the second transmission shaft 52 drives the cleaning shaft 3 to rotate through the third bevel gear 541 and the fourth bevel gear 542.

[0060] Embodiment 4: This embodiment differs from Embodiment 3 in that, referring to Fig.10 , Fig.11 The first cleaning shaft 31 is tubularly arranged so that the first cleaning shaft 31 has a liquid flow channel. The second cleaning shaft 33 is coaxially slidably inserted in the connecting sleeve 32. The upper part of the second cleaning shaft 33 is fixedly connected with a sliding plate 35 that is slidably connected to the connecting sleeve 32. The sliding plate 35 and the connecting sleeve 32 are connected by a key to achieve non-rotation relative to each other. The lower end surface of the first cleaning shaft 31 is fixedly connected with a fourth spring 34 built into the connecting sleeve 32. The end of the fourth spring 34 is fixedly connected to the sliding plate 35. Under normal conditions, the fourth spring 34 forces the second cleaning shaft 33 to slide away from the first cleaning shaft 31, so that the bristles 41 always abut against the upper end surface of the guide rail.

The water supply mechanism 7 includes a water tank 71 fixedly connected to the lower end surface of the vehicle plate 1, a water supply pipe 72 connected between the water tank 71 and the first cleaning shaft 31, and a pumping power assembly 73 for pumping the liquid in the water tank 71 to the first cleaning shaft 31. The mounting frame 14 is fixedly connected to the lower end surface of the water tank 71. The water supply pipe 72 includes an inlet pipe 721, a transition pipe 722, an outlet pipe 723 and a piston pipe 724. One end of the inlet pipe 721 is connected to the bottom wall of the water tank 71, and the other end of the inlet pipe 721 is connected to a water inlet one-way pipe 725, and the water inlet one-way pipe 725 is connected to one end of the transition pipe 722. One end of the water outlet pipe 723 is connected to the first cleaning shaft 31 through a rotary joint, and the other end of the water outlet pipe 723 is connected to a water outlet one-way pipe 726, which is connected to the other end of the transition pipe 722. The piston pipe 724 is connected to the middle peripheral wall of the transition pipe 722, so that the transition pipe 722 and the piston pipe 724 are T-shaped.

[0063] Reference Fig.12 , Fig.14 The first spring 727 is fixedly connected to one end of the water inlet one-way pipe 725 near the transition pipe 722, and the first spring 727 is fixedly connected to the water inlet plug 728 for controlling the opening and closing of the pipe mouth of the water inlet pipe 721. The second spring 729 is fixedly connected to one end of the water outlet one-way pipe 726 away from the transition pipe 722, and the second spring 729 is fixedly connected to the water outlet plug 720 for controlling the opening and closing of the pipe mouth of the water outlet one-way pipe 726. The pumping power assembly 73 includes a piston rod 731 slidably connected to the piston tube 724, an eccentric wheel 732 fixedly sleeved on the first cleaning shaft 31, and a third spring 733 built into the piston tube 724 to force the end of the piston rod 731 to abut against the outer peripheral wall of the eccentric wheel 732, and the eccentric wheel 732 is located above the fourth bevel gear 542. Under normal conditions, the first spring 727 forces the water inlet plug 728 to abut and block the pipe opening of the water inlet one-way pipe 725 away from the transition pipe 722 , and the second spring 729 forces the water outlet plug 720 to abut and block the pipe opening of the water outlet one-way pipe 726 close to the transition pipe 722 .

[0064] The implementation principle of a rail trolley with a rail cleaner in Example 4 is as follows: the rotation of the first cleaning shaft 31 drives the eccentric wheel 732 to rotate. When the distance between the contact point between the eccentric wheel 732 and the piston rod 731 and the axial center of the first cleaning shaft 31 changes from long to short, the piston rod 731 slides toward the first cleaning shaft 31, so that the volume of the cavity in the piston tube 724 increases, and the cavity in the piston tube 724 is negatively pressurized. The liquid in the water storage tank 71 pushes open the water inlet plug 728 and enters the transition pipe 722 from the water inlet pipe 721 and the water inlet one-way pipe 725 in turn. When the contact point between the eccentric wheel 732 and the piston rod 731 is at the first cleaning shaft 31, the piston rod 731 slides toward the first cleaning shaft 31, so that the volume of the cavity in the piston tube 724 increases. The cavity in the piston tube 724 is negatively pressurized, and the liquid in the water storage tank 71 pushes open the water inlet plug 728 and enters the transition pipe 722 from the water inlet pipe 721 and the water inlet one-way pipe 725 in turn. When the axial distance of the cleaning shaft 31 changes from short to long, the piston rod 731 slides toward the transition pipe 722 to squeeze the liquid. The liquid is pressed to open the water outlet plug 720 and enters the liquid flow channel of the first cleaning shaft 31 from the water outlet one-way pipe 726 and the water outlet pipe 723 in turn, and is sprayed from the spray holes on the spray plate 171 and the spray outer ring plate 172 to spray and reduce the dust raised by the cleaning parts during cleaning the guide rails, thereby ensuring the working environment. In addition, the liquid sprayed from the spray holes on the spray plate 171 splashes onto the back of the adjacent spray plate 171 to clean the dirt on the back of the spray plate 171.

[0065] Furthermore, when the liquid is pumped into the inner cavity of the connecting sleeve 32, the sliding plate 35 is subjected to the combined force of the liquid impact force and the fourth spring 34, sliding in the direction away from the first cleaning shaft 31, driving the second cleaning shaft 33 to slide in the direction close to the guide rail, so that the bristles 41 on the cleaning disc 4 are more closely attached to the upper end surface of the guide rail, thereby improving the cleaning effect.

[0066] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
