Description

Technical Field

[0001] The utility model belongs to the field of auxiliary equipment, relates to the field of fixture production, and specifically relates to a rack vehicle for transferring fixture plates. Background Art

[0002] During furniture production, boards are the main material of furniture, providing the basic structure and support for the furniture. After a series of processing such as cutting and grooving in the production and processing workshop, the processed boards need to be transferred to the assembly workshop for assembly.

[0003] In furniture production workshops, pallet trucks are usually used to transport panels. When transporting, pallet trucks have only one supporting surface, and the panels need to be stacked on the supporting surface. As the number of stacked panels increases, the pressure on the panels at the bottom of the supporting surface gradually increases, which can easily cause damage. In order to release the pressure on the bottom panels on the pallet truck, vertical racks are installed on the pallet truck, and the panels are loaded onto the racks layer by layer, so as to disperse the number of stacked panels and reduce the pressure on the panels.

[0004] However, when loading the plates onto the rack layer by layer, since the rack has a certain height, when the plates are loaded into the upper space of the rack, the plates need to be lifted to a certain height, so the operation will be more laborious, thereby increasing labor intensity and reducing operating efficiency. Utility Model Content

[0005] The utility model provides a furniture board transfer rack to solve the technical problems of difficult operation, time-consuming and labor-intensive operation when loading boards to the top of the rack. Multiple connecting rods vertically distributed in the frame can adjust their positions to load and unload boards on the support rods at the bottom of the frame, which is labor-saving and simple to use, and improves the use efficiency.

[0006] The technical solution adopted by the utility model is: to provide a furniture board transfer rack, comprising a base and a frame vertically arranged in the middle of the base, the frame and the base are fixedly installed, a control panel is arranged at intervals on one side of the frame, and the control panel is fixedly installed on the frame; a universal wheel is installed along the circumferential direction at the bottom end of the base; a driving shaft and a connecting shaft are rotatably installed on the control panel, the driving shaft and the connecting shaft are arranged up and down on the control panel, and are connected by means of a transmission member; a winding disk and a ratchet are coaxially installed on both sides of the connecting shaft, the winding disk is arranged between the frame and the control panel, and the ratchet is matched with a pawl, and the pawl is rotatably installed with the installation panel; a plurality of connecting rods are arranged in the frame for lifting and lowering by means of a guide assembly, the connecting rods are connected in series through connecting ropes, and the connecting rod at the top is fixedly connected with a traction rope, the traction rope passes through the frame upward, and is guided by the guide assembly to pass between the frame and the control panel, and is wound and connected with the winding disk; support rods are fixedly installed on both front and rear sides of the connecting rod with uniform inclination along the length direction, and the support rods are all inclined upward.

[0007] The traction rope is connected to the top connecting rod, so that the connecting rod is gradually pulled upward to facilitate the loading of the plates onto the support rod layer by layer, and the loading position is always located at the bottom of the frame. The loading is flexible and labor-saving, and the ratchet on the connecting shaft is engaged with the pawl to limit the rotation direction of the connecting shaft, so as to prevent the reel from releasing the traction rope, so that the connecting rod is kept in position in the frame, so that the loading and transportation of the plates are safe. When unloading the plates, the plates on the bottom connecting rod are unloaded first, and then the connecting rod is lowered layer by layer to unload the plates at the bottom of the frame. The operation is labor-saving and efficient.

[0008] To further optimize the technical solution, multiple pairs of assembly rod groups are fixedly installed on one side of the frame along the height direction, and the assembly rod groups include front and rear screw rods, and the screw rods all pass through the control panel and are threadedly connected with nuts; the outer walls of the screw rods are all covered with spacers, and the two ends of the spacers are respectively abutted against the outer wall of the frame and the outer wall of the control panel.

[0009] After the screw on the frame passes through the control panel, as the nut is tightened and abuts against the control panel, the two ends of the spacer on the screw respectively abut against the frame and the control panel and support them, so that a distance is maintained between the control panel and the frame, which is convenient for the insertion of the traction rope and the assembly of the reel, etc. The assembly is simple and the use is flexible.

[0010] To further optimize the technical solution, the transmission member includes a matching reduction gear set, which is arranged between the frame and the control panel and assembled with the drive shaft and the connecting shaft; the reduction gear set includes a driving gear coaxially assembled with the drive shaft and a driven gear coaxially assembled with the connecting shaft, and the diameter of the driving gear is smaller than the diameter of the driven gear.

[0011] The reduction gear set makes the driving shaft and the connecting shaft run synchronously. After the driving gear on the driving shaft meshes with the driven gear on the connecting shaft, the diameter of the driving gear is smaller than the driven gear, so that the driving shaft drives the connecting shaft to rotate with less effort, thereby saving effort in winding the traction rope of the winding reel.

[0012] To further optimize the technical solution, the reduction gear set is externally covered with a protective cover, which can be detachably mounted on the control panel with the aid of screws.

[0013] The protective cover prevents dust and impurities from affecting the meshing of the driving gear and the driven gear, thereby ensuring the stability of the operation of the reduction gear set. The detachable installation of the protective cover and the control panel facilitates the maintenance and protection of the reduction gear set and is flexible in use.

[0014] To further optimize the technical solution, the guide assembly includes at least two straight rods vertically arranged in the frame, both ends of the straight rods are disassembled and installed with the top wall and the bottom wall on the inner side of the frame by means of connecting pieces, and the connecting rods are slidably connected to the straight rods.

[0015] The straight rod supports and limits the connecting rod, so that the connecting rod can only be lifted and lowered vertically within the frame, and the use is stable and reliable.

[0016] To further optimize the technical solution, the connecting member includes flanges provided at both ends of the straight rod, the flanges are fixedly sleeved with the straight rod, and bolts are circumferentially provided on the flanges, and the bolts are all threadedly connected to the frame.

[0017] The straight rod is vertically installed with the frame through the flanges at both ends. It is firm and reliable to use, easy to assemble and disassemble, and flexible to use.

[0018] To further optimize the technical solution, the guide assembly includes guide wheels fixedly mounted on the top wall and side walls of the frame, and the traction rope passing through the frame passes around the guide wheels in sequence.

[0019] The traction rope passing through the frame is guided by the guide wheel and then passed between the frame and the control panel. The guide wheel guides the direction of the traction rope while reducing its traction resistance, making the traction more labor-saving.

[0020] To further optimize the technical solution, a protective sleeve is provided on the outer side of the support rod.

[0021] When the support plate supports the plate, the protective cover prevents the plate from being damaged, making the plate transportation safer.

[0022] The beneficial effects of the utility model are:

[0023] 1. When loading plates, the connecting rods in the frame are softly connected by linking ropes to facilitate their gathering at the bottom of the frame. After the plates are first loaded onto the support rods of the top connecting rods, the plates are loaded onto the support rods of the connecting rods layer by layer from top to bottom along the connecting rods by pulling each connecting rod up in sequence along the frame. The position of the connecting rods is adjustable, which is convenient for loading plates at the bottom of the frame, and the operation is labor-saving and simple.

[0024] 2. The driving shaft drives the connecting shaft to rotate through the reduction gear set, so that the winding disk reels the traction rope and pulls the connecting rod to move along the frame. The reduction gear set makes the driving shaft drive the connecting shaft to rotate with less effort, and the traction rope bypasses the guide wheel, which decomposes the force on the traction rope, and also makes the pulling of the connecting rod less effort;

[0025] 3. When the connecting shaft rotates, the ratchet on it engages with the pawl, limiting the connecting shaft to unidirectional rotation, that is, the rotation direction of the connecting shaft driving the reel to reel in the traction rope is not restricted, while the rotation direction of the connecting shaft driving the reel to release the traction rope is restricted, so that the traction rope pulls the connecting rod to move up along the frame smoothly and stably, and the connecting rod can be positioned at any time, which is flexible to use;

[0026] 4. When unloading the plate, first unload the plate on the connecting rod at the bottom of the frame, then push open the pawl to allow the connecting shaft to rotate in the opposite direction without restriction, and then lower the connecting rod to unload the plate at the bottom of the frame. Unloading saves effort. When the connecting shaft rotates in the direction of rotation, the speed of the driving shaft is controlled to control the downward movement speed of the connecting rod to avoid impact damage to the plate caused by stalling. During the unloading process of the plate, the pawl re-engages with the ratchet to limit the position of the connecting rod to ensure unloading safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] Please refer to the attached Figure 2 , Attachment Figure 4 , the connecting rods 5 in the frame 2 are connected in series through the connecting ropes 6, and the connecting rods 5 at the top have their outer walls fixedly connected with the traction ropes 7, which pass through the frame 2 upwards, and a control panel 3 is arranged at intervals on one side of the frame 2, and the control panel 3 is fixedly installed with the frame 2. A plurality of pairs of assembly rod groups are fixedly installed on one side of the frame 2 along the height direction, and the assembly rod groups are screw rods 201 arranged front and back, and the outer walls of the screw rods 201 are sleeved with spacers 203, and the free ends of the screw rods 201 pass through the control panel 3 and are connected with nuts 202. After the nuts 202 are tightened to abut against the control panel 3, the two ends of the spacers 203 on the screw rods 201 are respectively abutted against the outer walls of the frame 2 and the outer walls of the control panel 3, so as to support the control panel 3 and the frame 2 to maintain a spacing;

[0040] Please refer to the attached Figure 1 , Attachment Figure 7 , Attachment Figure 8, a driving shaft 301 and a connecting shaft 302 are rotatably installed on the control panel 3, the driving shaft 301 and the connecting shaft 302 are arranged on the control panel 3 from top to bottom, and are connected by means of a transmission member, the transmission member is a matching reduction gear set, the reduction gear set is arranged between the frame 2 and the control panel 3, and is assembled with the driving shaft 301 and the connecting shaft 302, the reduction gear set includes a driving gear 3011 coaxially assembled with the driving shaft 301 and a driven gear 3024 coaxially assembled with the connecting shaft 302, the diameter of the driving gear 3011 is smaller than the diameter of the driven gear 3024, so when the connecting shaft 302 is driven to rotate by rotating the driving shaft 301, the operation is more labor-saving, and the driving shaft 301 is equipped with a hand wheel, so that the rotation operation is labor-saving and simple, in order to ensure the service life of the reduction gear set, its external cover is provided with a protective cover 303, the protective cover 303 is detachably mounted with the control panel 3 by bolts 902, and its disassembly and maintenance are simple;

[0041] Please refer to the attached Figure 2 , a winding disk 3021 and a ratchet 3022 are coaxially mounted on both sides of the connecting shaft 302, the winding disk 3021 is arranged between the frame 2 and the control panel 3, and the traction rope 7 passing through the top of the frame 2 passes through the frame 2 and the control panel 3 with the help of a guide assembly, the guide assembly includes a guide wheel 204 fixedly mounted on the top wall and the side wall of the frame 2, the traction rope 7 passing through the frame 2 passes around the guide wheel 204 in turn, and is guided to between the frame 2 and the control panel 3, and is wound and connected with the winding disk 3021, so that the winding disk 3021 winds or releases the traction rope 7 by rotating the driving shaft 301, and the operation is simple;

[0042] Please refer to the attached Figure 6 The ratchet wheel 3022 coaxially assembled with the connecting shaft 302 is arranged on a side away from the frame 2, and the pawl 3023 matched with the ratchet wheel 3022 is rotatably mounted on the control panel 3. When the pawl 3023 is engaged with the ratchet wheel 3022, the connecting shaft 302 is restricted to unidirectional rotation, that is, the connecting shaft 302 drives the winding disk 3021 to rotate unidirectionally and winds the traction rope 7 to restrict the winding disk 3021 from releasing the traction rope 7, so that the connecting rod 5 can only move upward along the frame 2;

[0043] Please refer to the attached Figure 2 , Attachment Fig. 9 The front and rear ends of the outer wall of the connecting rod 5 are evenly inclined along the length direction with support rods 8, and the support rods 8 are all inclined upward. When the support rods 8 support the plate, the plate is moved closer to the connecting rod 5 along the support rods 8, thereby preventing the plate from sliding off the support rods 8, improving the safety of the plate during transportation, and the outer cover of the support rod 8 is provided with a protective cover 801 to prevent the plate from bumping;

[0044] The working principle of the furniture board transfer trolley is as follows: when loading boards, the connecting rods 5 in the frame 2 gather together at the bottom of the frame 2, and the connecting rods 5 are softly connected by the connecting ropes 6, so as not to interfere with the gathering of the connecting rods 5. The boards are first loaded onto the support rods 8 of the top connecting rods 5. The inclined setting of the support rods 8 makes the boards slide toward the connecting rods 5 and the frame 2 to prevent the boards from slipping off the support rods 8. After the top connecting rod 5 is loaded with boards on both sides, the driving shaft 301 is rotated, and the winding disk 3021 on the connecting shaft 302 is driven by the reduction gear group to wind and collect the traction rope 7, so as to pull the top connecting rod 5 upward to increase the interval between it and the lower connecting rod 5, so that the board loading is not interfered. As the connecting rods 5 in the frame 2 move up along the frame 2 in turn, the connecting rods 5 and the support rods 8 support the boards layer by layer, so that the loading position of the boards is always located at the bottom of the frame 2, making loading convenient and labor-saving.

[0045] When the driving shaft 301 drives the connecting shaft 302 to rotate through the reduction gear set, the driving gear 3011 on the driving shaft 301 meshes with the driven gear 3024 on the connecting shaft 302. The driving gear 3011 has a smaller diameter than the driven gear 3024, and is a labor-saving gear set in which a small gear drives a large gear, so that the winding disk 3021 can wind the traction rope 7 with less effort. At the same time, after the traction rope 7 on the connecting rod 5 passes through the frame 2, it passes around the guide wheels 204 on the top and side walls of the frame 2 in turn. The guide wheels 204 decompose the force on the traction rope 7, so that the pulling of the connecting rod 5 is more labor-saving.

[0046] When the connecting shaft 302 rotates to drive the reel 3021 to reel in the traction rope 7, the ratchet 3022 on the connecting shaft 302 meshes with the pawl 3023 on the control panel 3 to limit the unidirectional rotation of the connecting shaft 302, that is, the rotation direction of the reel 3021 driven by the connecting shaft 302 to reel in the traction rope 7 is not restricted, while the rotation direction of the reel 3021 driven by the connecting shaft 302 to release the traction rope 7 is restricted, so that the traction rope 7 pulls the connecting rod 5 to move upward along the frame 2 smoothly and stably;

[0047] When unloading the plates, first unload the plates loaded on the bottom connecting rod 5 in the frame 2, and then push open the pawl 3023 to make the connecting shaft 302 unrestricted, and then make the connecting shaft 302 rotate in the opposite direction, release the traction rope 7, and make the connecting rod 5 move down gradually, so as to unload the plates at the bottom of the frame 2. When the connecting shaft 302 rotates in the opposite direction, the downward movement speed of the connecting rod 5 is controlled by controlling the rotation speed of the driving shaft 301 to avoid stalling. After the connecting rod 5 is lowered to the appropriate position, the pawl 3023 is used to lock the ratchet 3022 to support the position of the connecting rod 5, which is convenient for unloading and labor-saving and flexible to use.
