Description

Technical Field

[0001] The utility model belongs to the technical field related to rail transport vehicles, and in particular relates to a rail transport vehicle which is convenient for positioning. Background Art

[0002] Rail transport vehicles are widely used in various automatic production lines and unmanned storage equipment to achieve production automation and efficient operation. During the transportation process of rail transport vehicles, some goods need to be transported to various transfer workstations for other processes. In this link, the positioning of rail transport vehicles is required to ensure that the operation can be carried out accurately, which can better transport goods and ensure the failure of factory cargo transportation. However, it still has the following disadvantages in actual use:

[0003] 1. During the operation of the rail transport vehicle, the positioning device is directly used. After it moves to the appropriate position, it is positioned and braked. The braking stroke is long, which causes the transport vehicle to take a long time to stop each time it starts braking. The braking kinetic energy is large, which is prone to safety hazards during operation;

[0004] 2. When the rail transport vehicle brakes, it adopts fixed-point direct braking. After braking, the rail transport vehicle will slide a certain distance. During the braking process, the braking effect is directly applied to all wheels, and the sliding distance cannot be controlled. Therefore, the movement accuracy of the transport vehicle will not be high enough after it stops. Utility Model Content

By setting a cement floor, a transport vehicle shell and a magnetic strip, the utility model solves the problems that the rail transport vehicle requires a long time to brake, the high braking kinetic energy is prone to safety hazards, and the positioning accuracy of the rail transport vehicle is not high enough.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model is a rail transport vehicle which is easy to position, comprising a cement floor, a transport vehicle shell and a magnetic strip, wherein the transport vehicle shell is arranged on the top of the cement floor, a fixing opening is opened on the top of the cement floor, a magnetic strip is fixed in the fixing opening, the bottom of the transport vehicle shell is arranged in an open manner, a battery is fixed in the center of the top inside the transport vehicle shell, a control box is fixed in the center of the bottom of the battery, photoelectric switches are fixed at both ends of the control box, when working, the running track is embedded and fixed in it through the cement floor, the battery is fixed in it through the transport vehicle shell, the control box is fixed in it through the battery, the magnetic disk is adsorbed by the magnetic strip, so that the magnetic disk is pressed onto the slow switch, so that the double-headed motor drives the roller to rotate slowly.

[0008] Furthermore, running tracks are embedded and fixed on both sides of the fixing opening at the top of the cement floor. The fixing opening is arranged between the two running tracks, and the length direction of the fixing opening is parallel to the length direction of the running track. The running track is embedded and fixed thereon through the cement floor.

[0009] Furthermore, double-headed motors are fixed at the two short side edges of the top of the transport vehicle shell, and driving shafts are fixed at the two output ends of the double-headed motor. When the transport vehicle shell is driven by the double-headed motor, the driving shaft is driven to rotate.

[0010] Furthermore, a roller is fixed to one end of the driving shaft away from the double-headed motor, and the roller is rotatably connected to the outer shell of the transport vehicle. The lower part of the roller is movably connected in the running track, and a brake assembly is movably connected to the outer side of one end of the two driving shafts close to the roller. The top of the brake assembly is fixed to the inner top of the outer shell of the transport vehicle. When the driving shaft rotates, the roller is driven to rotate, driving the transport vehicle body to move, and the roller is braked by the brake assembly.

[0011] Furthermore, a slow switch is fixed at the center of the inner bottom of the control box, a compression spring is fixed at the inner bottom of the control box outside the slow switch, a magnetic disk is fixed on the top of the compression spring, and a pressure rod is fixed at the center of the bottom end of the magnetic disk. The slow switch is fixed in it through the control box, and after the magnetic disk is adsorbed by the magnetic bar, the pressure rod on the magnetic disk is pressed onto the slow switch, thereby starting the double-headed motor to slowly drive the drive shaft to rotate.

[0012] Furthermore, a reflector is fixed at the top center of the magnetic strip, and reflective sheets are fixed at both ends of the reflector. The two reflectors correspond to the positions of two photoelectric switches one by one, and the magnetic strip cooperates with the photoelectric switch to start the brake assembly through the reflector.

[0013] The utility model has the following beneficial effects:

[0014] 1. The utility model solves the problems of long braking time and high braking kinetic energy that may easily cause safety hazards of rail transport vehicles by arranging cement floors, transport vehicle shells and magnetic strips. After placing the goods on the transport vehicle shell, two double-headed motors are immediately started, and the driving shafts are driven to rotate by the two double-headed motors. When the driving shafts rotate, the rollers are driven to move on the running track. When the transport vehicle shell in operation passes over the magnetic strip and is adsorbed by the magnetic strip through the magnetic disk, the magnetic disk drives the pressure rod to press down the slow switch, so that the slow switch is turned on, and the double-headed motor drives the rollers to rotate slowly, so that the rail transport vehicle can fully decelerate before braking, the braking time is shorter, the braking kinetic energy is lower, and the safety hazards are smaller.

[0015] 2. The utility model solves the problem of insufficient accuracy in the stopping position of the rail transport vehicle by providing a transport vehicle shell and a magnetic strip. When the light emitted by a photoelectric switch is reflected by the reflective sheet and returns to the photoelectric switch, two brake assemblies close to the photoelectric switch are started, and the two double-headed motors are turned off to brake the two rollers close to the photoelectric switch. At the same time, due to inertia, the transport vehicle shell continues to move until the light emitted by another photoelectric switch contacts the reflective sheet. The four brake assemblies are turned on to brake the rollers at the same time, so that the transport vehicle shell stops at an accurate position, so that the stopping position of the rail transport vehicle is more accurate during operation.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1

[0026] See also Figure 1-5 The utility model is a rail transport vehicle that is easy to position, including a cement floor 1, a transport vehicle shell 2 and a magnetic strip 3. The transport vehicle shell 2 is arranged on the top of the cement floor 1, and the cement floor 1 embeds and fixes the running track 101 therein, and the battery 204 and the double-headed motor 201 are fixed therein through the transport vehicle shell 2. A fixing port 102 is opened on the top of the cement floor 1, and the cement floor 1 fixes the magnetic strip 3 through the fixing port 102. The magnetic strip 3 is fixed in the fixing port 102, and the magnetic disk 207 is adsorbed by the magnetic strip 3. The bottom of the transport vehicle shell 2 is open, and a battery 204 is fixed in the center of the top of the transport vehicle shell 2. The transport vehicle shell 2 supplies power to the double-headed motor 201 through the battery 204. A control box 205 is fixed in the center of the bottom of the battery 204, and a slow switch 210 is fixed therein through the control box 205. Photoelectric switches 206 are fixed at both ends of the control box 205. After the reflective sheet 302 reflects light onto it, the brake assembly 211 at the corresponding position is opened by the photoelectric switch 206.

[0027] Specifically, running tracks 101 are embedded and fixed on both sides of the fixed opening 102 at the top of the cement floor 1. The fixed opening 102 is set between the two running tracks 101, and the length direction of the fixed opening 102 is parallel to the length direction of the running track 101. The cement floor 1 movably connects the roller 203 therein through the running track 101 to limit the running track of the transport vehicle shell 2.

[0028] Furthermore, a double-headed motor 201 is fixed to the two short edges of the top of the transport vehicle shell 2, and a driving shaft 202 is fixed to the two output ends of the double-headed motor 201. The transport vehicle shell 2 drives the driving shaft 202 to rotate through the double-headed motor 201.

[0029] Furthermore, a roller 203 is fixed to one end of the driving shaft 202 away from the double-headed motor 201, and the roller 203 is rotatably connected to the transport vehicle shell 2. The lower part of the roller 203 is movably connected in the running track 101, and a brake assembly 211 is movably connected to the outer side of one end of the two driving shafts 202 close to the roller 203. The top of the brake assembly 211 is fixed to the inner top of the transport vehicle shell 2. When the driving shaft 202 is driven by the double-headed motor 201, the roller 203 is driven to rotate. When the roller 203 rotates, the transport vehicle shell 2 moves on the running track 101. When a photoelectric switch 206 is turned on, the two brake assemblies 211 close to the photoelectric switch 206 are started. When the two photoelectric switches 206 are turned on, all the brake assemblies 211 are started to stop the transport vehicle shell 2.

[0030] Furthermore, a slow switch 210 is fixed at the center of the inner bottom of the control box 205, and a compression spring 209 is fixed at the inner bottom of the control box 205 outside the slow switch 210. A magnetic disk 207 is fixed to the top of the compression spring 209, and a pressure rod 208 is fixed at the center of the bottom end of the magnetic disk 207. When the running transport vehicle shell 2 passes over the magnetic strip 3 and is adsorbed by the magnetic strip 3 through the magnetic disk 207, the magnetic disk 207 drives the pressure rod 208 to press down the slow switch 210, so that the slow switch 210 is opened, and the double-headed motor 201 drives the roller 203 to rotate slowly.

[0031] The operation process of this embodiment is: when working, after placing the goods on the transport vehicle shell 2, the two double-headed motors 201 are started immediately, and the driving shaft 202 is driven to rotate by the two double-headed motors 201. When the driving shaft 202 rotates, the roller 203 is driven to move on the running track 101. When the transport vehicle shell 2 in operation passes over the magnetic strip 3, it is adsorbed by the magnetic strip 3 through the magnetic disk 207. The magnetic disk 207 drives the pressure rod 208 to press down the slow switch 210, so that the slow switch 210 is opened, so that the double-headed motor 201 drives the roller 203 to rotate slowly. Specific embodiment 2

[0033] See also Figure 1-5 On the basis of the first specific embodiment, a reflector 301 is fixed to the top center of the magnetic strip 3, and reflectors 302 are fixed to both ends of the reflector 301. The two reflectors 302 correspond to the positions of the two photoelectric switches 206. The magnetic strip 3 fixes the reflector 302 thereon through the reflector 301, and maintains the photoelectric switch 206 open through the reflector 302. After the reflector 302 reflects light, the photoelectric switch 206 is turned on, and the four brake components 211 are activated to stop the housing 2 of the transport vehicle on the cement floor 1.

[0034] The operation process of this embodiment is as follows: during operation, when the transport vehicle shell 2 passes over the magnetic strip 3 on the top of the cement floor 1, the transport vehicle shell 2 continues to move until the light emitted by a photoelectric switch 206 is reflected by the reflective sheet 302 and returns to the photoelectric switch 206, and then the two brake assemblies 211 close to the photoelectric switch 206 are started, and the two double-headed motors 201 are turned off to brake the two rollers 203 close to the photoelectric switch 206. At the same time, due to inertia, the transport vehicle shell 2 continues to move until the light emitted by another photoelectric switch 206 contacts the reflective sheet 302, and the four brake assemblies 211 are opened at the same time to brake the rollers 203, so that the transport vehicle shell 2 stops at the correct position.
