Description
Technical Field
[0001] The utility model relates to the technical field of forklifts, in particular to a guide rail type guiding device for a picking forklift. Background Art
[0002] With the development of e-commerce and supply chain management, picking forklifts are increasingly used in logistics warehouses. Drivers drive forklifts to the cargo area to pick up goods and transport them from the storage area to the packaging area or shipping area. In large warehouses, in order to improve the efficiency of workers' picking operations, guide tracks are laid along the shelves in the warehouse, and guide wheels are installed on the picking forklifts to cooperate with the tracks for guiding operation. However, the guide wheels installed on traditional picking forklifts are rigidly connected to the body of the forklift. When the forklift is driving on the guide rails, it will produce rigid impact and vibration with the rails, and the body of the forklift will shake greatly.
[0003] In addition, currently, picking forklifts are mainly controlled by the driver and passengers manually operating the electric steering wheel to control their driving direction. When driving on the track, the driver and passengers may mistakenly operate the electric steering wheel, causing the forklift to collide with the track, resulting in the risk of damage to the forklift and the goods on the forklift, and seriously affecting the comfort of the driver and passengers. Utility Model Content
[0004] In order to solve the above existing problems, the utility model provides a guide rail type guide device for a picking forklift, which facilitates the picking forklift to travel straight on the track, reduces the collision between the forklift and the track due to misoperation, and improves safety.
[0005] The technical solution of the utility model is as follows:
[0006] A guide rail guide device for a picking forklift, comprising a guide frame installed on a forklift frame, and a guide wheel installed at the end of the guide frame, a micro switch is installed on the top surface of the guide frame, a mounting bracket that moves along the length direction of the guide frame is movably provided on the guide frame, and the guide wheel is installed at the end of the mounting bracket; a limit block is installed on the top of the mounting bracket, and the limit block and the micro switch are located on the same straight line; the mounting bracket moves to make the limit block contact or separate from the micro switch.
[0007] The signal end of the micro switch is electrically connected to the controller of the forklift, and the output end of the controller is connected to the power supply end of the electric steering wheel to control the on and off of the electric steering circuit.
[0008] In a further solution, the guide frame is a cylindrical structure with openings at both ends, and the mounting bracket enters into the inner cavity of the guide frame from an opening at one end and moves horizontally.
[0009] In a further solution, a movable groove is provided on the top surface of the guide frame, and the limit block is fixed to the top surface of the mounting bracket and is located in the movable groove for horizontal movement.
[0010] In a further solution, a horizontal guide shaft is fixedly provided at the front end of the mounting bracket, and a telescopic member is sleeved on the guide shaft.
[0011] Preferably, the telescopic member is a compression spring, one end of which is fixed on the mounting bracket and the other end of which is a free end extending out of the end of the guide shaft.
[0012] According to a further solution, the mounting bracket includes an upper bracket, a lower bracket, and a support frame connecting the upper and lower brackets into one body, the ends of the upper and lower brackets are provided with pin holes, the guide wheel is clamped between the upper and lower brackets, and the guide wheel is fixed to the upper and lower brackets with a pin.
[0013] According to a further solution, a mounting base plate and a rib plate are respectively fixedly provided on the guide frame.
[0014] The guide device of the utility model is provided with a micro switch. When the vehicle travels on the guide rail, the thrust of the guide wheel causes the mounting bracket to move with the limit block in a direction away from the micro switch, thereby separating the micro switch from the limit block, the micro switch circuit is connected and sends a signal to the controller of the forklift, the controller disconnects the power supply of the electric steering wheel, the electric steering wheel steering fails, that is, the driver and passengers cannot perform steering operation on the electric steering wheel, thereby making the forklift move in a straight line along the track through the guide wheel, avoiding the collision between the forklift and the track due to the misoperation of the driver and passengers, and improving the driving safety.
[0015] In addition, a compression spring is provided on the mounting bracket of the device, which can not only absorb part of the thrust of the guide wheel and reduce the shaking of the forklift, but also use its elasticity to move the mounting bracket toward the micro switch, so that the micro switch contacts the limit block and disconnects the signal, allowing the forklift to travel at normal speed after leaving the guide rail.

[0021] Install the base plate 1, the limit block 2, the micro switch 3, the guide frame 4, the movable groove 4-1, the rib plate 5, the compression spring 6, the mounting bracket 7, the pin shaft 8, the guide wheel 9, and the guide shaft 10. DETAILED DESCRIPTION
[0022] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.
[0023] See also Figure 1-4 The utility model provides a guide rail guide device for a picking forklift, comprising a guide frame 4 installed on a forklift frame, and a guide wheel 9 installed at the end of the guide frame, a micro switch 3 is installed on the top surface of the guide frame 4, a mounting bracket 7 that moves along the length direction of the guide frame is movably provided on the guide frame 4, and the guide wheel 9 is installed at the end of the mounting bracket 7; a limit block 2 is installed on the top of the mounting bracket 7, and the limit block 2 and the micro switch 3 are located on the same straight line; the mounting bracket 7 moves to make the limit block 2 contact or separate from the micro switch 3.
[0024] The micro switch 3 of the utility model is a normally open switch, and its signal end is electrically connected to the existing controller on the forklift. When the limit block 2 is separated from the micro switch 3, the micro switch 3 is closed, and its signal is transmitted to the controller. The controller disconnects the power supply of the electric steering wheel, and the electric steering wheel steering fails, that is, the driver and passengers cannot steer the electric steering wheel, so that the forklift moves in a straight line along the track through the guide wheel, avoiding the collision between the forklift and the track due to the misoperation of the driver and passengers, and improving the driving safety.
[0025] Specifically, the guide frame 4 is a cylindrical structure with openings at both ends, and the mounting bracket 7 enters the inner cavity of the guide frame 4 from one end opening and moves horizontally. The top surface of the guide frame 4 is provided with a movable groove 4-1, and the limit block 2 is fixed to the top surface of the mounting bracket 7 and is located in the movable groove 4-1 for horizontal movement.
[0026] In a further solution, a horizontal guide shaft 10 is fixedly provided at the front end of the mounting bracket 7, and a telescopic member is sleeved on the guide shaft 10. In this embodiment, the telescopic member is a compression spring 6, one end of the compression spring 6 is fixed on the mounting bracket 7, and the other end is a free end and extends out of the end of the guide shaft 10.
[0027] That is, the travel of the mounting bracket 7 is limited by the guide shaft and the movable groove 4-1. When the mounting bracket 7 moves toward the mounting base plate 1, the compression spring 6 will be compressed. When the front end of the guide shaft contacts the mounting base plate 1, the compression spring 6 reaches its maximum compression travel. Figure 3 As shown. At this time, the limit block 2 moves in the movable groove 4-1 and moves away from the micro switch 3, that is, the micro switch 3 and the limit block are separated to generate an electrical signal sent to the control system of the forklift, indicating that the forklift is traveling on the track. When the forklift leaves the guide rail, the compression spring 6 rebounds, so that the mounting bracket 7 and the guide wheel 9 return to the initial position, and the limit block 2 moves together and re-contacts with the micro switch 3.
[0028] Specifically, the mounting bracket 7 includes an upper bracket, a lower bracket, and a support frame connecting the upper and lower brackets into one body. The ends of the upper and lower brackets are provided with pin holes. The guide wheel is clamped between the upper and lower brackets, and the guide wheel is fixed to the upper and lower brackets by a pin 8. That is, the overall structure of the mounting bracket in the utility model is symmetrical, which improves the balance of its movement in the guide frame 4. The guide wheel is installed by the pin 8, and the overall operation is simple and easy to disassemble and assemble.
[0029] In addition, the micro switch, limit block, etc. in the utility model are fixedly installed with bolts, which is convenient for later maintenance and replacement operations.
[0030] The guide frame 4 is respectively fixed with a mounting base plate 1 and a rib plate 5. That is, the guide device of the utility model is respectively fixedly mounted on the frame of the forklift through the mounting base plate 1 and the rib plate 5, wherein the rib plate 5 can enhance the stability of the connection between the guide device and the frame.
[0031] When the forklift is traveling on the track, the guide wheel contacts the wall of the track, generating a thrust on the guide wheel and the mounting bracket, pushing the mounting bracket 7 to move backward in the guide frame 4. The compression spring absorbs part of the impact force, reducing the shaking of the forklift, thereby improving the comfort of the driver and passengers. At the same time, the mounting bracket 7 drives the limit block 2 to separate from the micro switch 3 (such as Figure 3 ), the micro switch is closed, and the closing signal is sent to the forklift controller. The controller sends a signal to stop the power supply to the electric steering wheel, and the steering wheel fails, thus avoiding the collision between the forklift and the track due to the driver's misoperation, and improving the driving safety. When the forklift leaves the track, the mounting bracket returns to its original position with the limit block 2, so that the limit block 2 and the micro switch 3 are in contact again (such as Figure 4 ), the micro switch 3 disconnects the signal from the controller, and the electric steering wheel can steer normally.
[0032] Although this specification is described according to implementation modes, not every implementation mode includes only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
[0033] Therefore, the above description is only a preferred embodiment of the present application and is not intended to limit the scope of implementation of the present application; that is, all equivalent changes made according to the scope of the claims of the present application are within the protection scope of the claims of the present application.
