Description

Technical Field

[0001] The present application relates to the field of workpiece processing auxiliary tools, and in particular to a support for grinding forklift overhead guard legs. Background Art

[0002] The forklift overhead guard leg is an important part of the forklift overhead guard structure. Its main function is to support the overhead guard and withstand various forces from above to protect the forklift driver from falling objects. Among them, the bent part of the forklift overhead guard leg is the most important load-bearing part of the entire leg structure.

[0003] Reference Figure 1 During the actual processing of the forklift overhead guard leg (hereinafter referred to as the leg 6), there are usually sharp edges or burrs on the edges, which need to be smoothed to ensure safety; however, the overall structure of the leg 6 is relatively special, and it is inconvenient to move it. In addition, when grinding the welding parts on both sides of the leg 6, the operator usually chooses to place the leg 6 on the ground. After grinding one side of the leg 6, the operator manually turns the leg over and grinds the other side of the leg 6.

[0004] Based on this, this operation method requires the operator to squat, which is very inconvenient and puts a certain amount of physical strain on the operator. Therefore, the legs 6 are often placed on a support to perform the grinding operation, thereby improving the situation where the operator needs to bend over. The legs 6 in the prior art generally include a base 1, a support rod 2 vertically fixed to the base 1, and a placement platform 32 provided on one side of the support rod 2, and the placement platform 32 is used to place the legs 6.

[0005] However, the placement table on the support is welded and fixed to the support rod. When the support leg is being polished, one side of the support leg will partially abut against the support rod, and the side of the support rod will be partially blocked. Therefore, when the support leg is placed on the placement table, the support leg needs to be turned over for adjustment. Due to the heavy weight of the support leg, additional labor intensity will be caused, resulting in high labor intensity for the operators, which needs to be improved. Utility Model Content

[0006] Based on this, the present application provides a support for grinding the legs of a forklift overhead guard. By adjusting the position angle of the placement table on the support rod, it is convenient for the operator to place the leg on the placement table and fully expose the surface to be ground of the leg, thereby reducing the labor intensity of the operator.

[0007] The present application provides a forklift overhead guard leg grinding support using the following technical solution:

[0008] A support for grinding the legs of a forklift overhead guard frame includes a base, a support rod arranged on the base, and a placement mechanism arranged on the side of the support rod, wherein the support rod includes a round rod segment, and the placement mechanism includes a rotating table rotatably sleeved on the round rod segment and a placement table slidably arranged on the outer peripheral side of the rotating table, and a limiting structure is provided between the placement table and the support rod; when the leg is placed on the placement table, the placement table and the support rod maintain circumferential positioning through the limiting structure.

[0009] By adopting the above-mentioned technical solution, the leg grinding device of the present application is placed on the ground foundation via a base. When the operator carries the leg and places it on the placement table, the placement table can be adjusted to the desired position by adjusting the placement table to rotate the entire placement mechanism circumferentially around the central axis of the support rod. After the operator places the leg on the placement table, the surface of the leg to be ground can be fully exposed, making it easier for the operator to perform the grinding operation and reducing the operator's labor intensity. In addition, after the operator places the leg on the placement table, the placement table is subjected to the gravity of the leg and can maintain the circumferential positioning of the placement table through the limit structure, thereby improving the operator's convenience in grinding the leg.

[0010] Optionally, the limiting structure includes a polygonal column sleeve fixedly mounted on the round rod segment and a socket arranged at the bottom of the placement table, the socket being provided with a prismatic groove, and when the support leg is placed on the placement table, the polygonal column sleeve matches and abuts against the side wall of the prismatic groove; a first spring is arranged between the placement table and the rotating table, and the first spring is used to force the socket to normally detach from the polygonal column sleeve.

[0011] By adopting the above technical solution, the first spring disposed between the placement platform and the rotating platform can constantly generate an elastic force acting on the placement platform, thereby forcing the socket to normally disengage from the polygonal column sleeve, allowing the placement platform to smoothly rotate circumferentially about the central axis of the rotating platform. When the legs are placed on the placement platform, the weight of the legs acts on the placement platform, causing it to move downward, ultimately allowing the socket to mate with the polygonal column sleeve, thereby achieving circumferential positioning of the placement platform relative to the support rod.

[0012] Optionally, a sliding slot is provided on the outer circumference of the rotating table, a sliding block is fixed on the inner side of the placement table, and the sliding block is slidably arranged inside the sliding slot; the first spring is arranged between the sliding block and the bottom wall of the sliding slot.

[0013] By adopting the above-mentioned technical solution, the sliding block of the placement table is slidably installed in the sliding slot of the rotating table. When the operator moves the placement table, the placement table and the rotating table can be rotated circumferentially around the central axis of the support rod; the elastic force of the first spring acting on the sliding block can force the sliding block to move in the direction away from the bottom wall of the sliding slot, thereby causing the placement table to move upward normally, so that the sleeve is in a position separated from the polygonal column sleeve.

[0014] Optionally, an abutment portion is partially provided on the inner wall of the placement table, and the first spring is used to force the abutment portion to normally abut against the rotating table. At this time, the placement table is higher than the rotating table.

[0015] By adopting the above-mentioned technical solution and setting the abutment portion, after the elastic force generated by the first spring acting on the first clamping block forces the placement table to move upward, the abutment portion can abut against the bottom of the rotating table, thereby limiting the situation where the placement tables are separated from the rotating table, which is conducive to ensuring the normal use of the placement mechanism.

[0016] Optionally, a stopper is provided on the outer side surface of the placement table, and the top surface of the stopper is higher than the top surface of the placement table.

[0017] By adopting the above-mentioned technical solution, the setting of the baffle can protect the outer side of the leg after the leg is placed on the placement table, and can limit the leg, so that when people accidentally touch the leg while walking, the possibility of the leg moving, flipping, and falling to the ground is reduced, thereby reducing the possibility of people being injured by the leg and reducing safety hazards.

[0018] Optionally, a hollow sleeve is fixed to the top surface of the base, and the support rod is movably inserted inside the hollow sleeve; a plurality of limit grooves are provided on the outer peripheral surface of the support rod, and each limit groove is arranged at intervals along the axial direction of the support rod; the hollow sleeve is provided with a positioning mechanism for engaging with the limit groove for limiting the position.

[0019] By adopting the above-mentioned technical solution, by movably inserting the support rod into the hollow sleeve, the positioning mechanism is engaged with different limit grooves, and the height of the placement mechanism can be adjusted, thereby improving the bending situation of the operator when grinding the support legs at different heights and reducing the labor intensity of the operator.

[0020] Optionally, the positioning mechanism includes a plug-in column movably inserted into the hollow sleeve and a second spring arranged between the plug-in column and the hollow sleeve, and the second spring is used to force the plug-in column to be matched and inserted into the limiting groove.

[0021] By adopting the above technical solution, the setting of the second spring can always generate elastic force acting on the plug-in column, thereby forcing the plug-in column to move inward and match and be inserted into the limit groove to achieve adjustment and positioning of the support rod on the hollow sleeve.

[0022] Optionally, guide surfaces are provided at the corners of the bottom of the plug-in column.

[0023] By adopting the above-mentioned technical solution, by setting a guide surface at the corner of the bottom of the plug-in column, the operator can directly apply an upward force to the support rod to force the support rod to move upward, which can facilitate the operator to grind from the upper part of the leg to the lower part of the leg in sequence; after the leg is completely polished, the leg is moved away from the placement seat, and then the plug-in column is manually forced to move outward to disengage from the limit slot, and the support rod can be smoothly retracted downward to facilitate the next leg grinding operation.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. By rotating the rotating table and sleeved on the support rod, the placement table can be moved to make the entire placement mechanism rotate circumferentially around the central axis of the support rod, thereby adjusting the placement table to the desired position. After the operator places the leg on the placement table, the surface to be polished of the leg can be fully exposed, making it easier for the operator to perform the polishing operation and reducing the operator's labor intensity;

[0026] 2. A first spring is provided to generate an elastic force acting on the placement platform, forcing the socket to normally separate from the polygonal column sleeve. When the legs are placed on the placement platform, the weight of the legs acts on the placement platform, causing it to move downward, and ultimately the socket can be matched and sleeved on the polygonal column sleeve, thereby achieving circumferential positioning of the placement platform relative to the support rod.

[0027] 3. By movably inserting the support rod into the hollow sleeve, the positioning mechanism is engaged with different limit slots, and the height of the placement mechanism can be adjusted. Therefore, when grinding the legs at different heights, the bending of the operator can be improved, thereby reducing the labor intensity of the operator. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The following is combined with Figure 2-6 This application is described in further detail.

[0036] The embodiment of the present application discloses a support for grinding a forklift overhead guard leg.

[0037] Reference Figure 2 A support for grinding the legs of a forklift overhead guard frame includes a base 1, a support rod 2 and a placement mechanism 3, wherein the support rod 2 includes an integrally formed round rod segment 21 and a square rod segment 22, and the round rod segment 21 is located above the square rod segment 22; a hollow sleeve 11 is fixed to the top of the base 1, and the internal dimensions of the hollow sleeve 11 are set equal to the external dimensions of the square rod segment 22, so that the support rod 2 can be movably inserted into the hollow sleeve 11 and the circumferential rotation of the support rod 2 around its own central axis is restricted.

[0038] Reference Figure 3 The outer surface of the square rod section 22 is provided with a plurality of limiting grooves 24, and each limiting groove 24 is located on the same side of the square rod section 22, and all limiting grooves 24 are equidistantly arranged along the axial direction of the support rod 2; the hollow sleeve 11 is installed with a positioning mechanism 5, and the positioning mechanism 5 can be engaged with the limiting groove 24 to realize the position positioning of the support rod 2 on the hollow sleeve 11.

[0039] Specifically, the outer circumference of the hollow sleeve 11 is provided with a movable groove 12 that is connected to the interior of the hollow sleeve 11. The positioning mechanism 5 includes a plug-in post 51 and a second spring 52. The outer dimensions of the plug-in post 51 are set to be equal to the inner dimensions of the movable groove 12, so that the plug-in post 51 can be inserted into the movable groove 12 and move within the movable groove 12. A bracket plate 13 is fixedly mounted on the outer circumference of the hollow sleeve 11. The plug-in post 51 is movably inserted into the bracket plate 13, and a load-bearing portion 512 is partially fixed to the plug-in post 51. The load-bearing portion 512 is located between the bracket plate 13 and the hollow sleeve 11. The second spring 52 is sleeved on the plug-in post 51. One end of the second spring 52 abuts against the bracket plate 13, and the other end abuts against the load-bearing portion 512. The second spring 52 can always generate an elastic force acting on the load-bearing portion 512, thereby forcing the plug-in post 51 to normally abut against the outer circumference of the hollow sleeve 11.

[0040] The outer dimensions of the plug post 51 are also designed to be equal to the inner dimensions of the retaining groove 24. When the support rod 2 is moved to a position where the plug post 51 is directly opposite the retaining groove 24, the elastic force of the second spring 52 allows the plug post 51 to be inserted into the retaining groove 24, thereby achieving the movable positioning of the support rod. In addition, a manipulation portion 513 is fixed to the end of the plug post 51 away from the hollow sleeve 11. The manipulation portion 513 is located on the side of the bracket plate 13 away from the hollow sleeve 11 and is used by an operator to manipulate the plug post 51 to force it out of the retaining groove 24, thereby adjusting the height of the support rod 2.

[0041] It should be noted here that the corners at the bottom of the plug-in column 51 are rounded to form a guide surface 511. When the operator directly pulls the support rod 2 upward, the side wall of the limit groove 24 can abut against the guide surface 511 and automatically force the plug-in column 51 to move outward, so as to facilitate the raising of the support rod 2, facilitate the subsequent grinding from the upper part of the support leg 6 to the lower part of the support leg 6, and improve the convenience of operation.

[0042] Reference Figure 4 、 Figure 5 The cross-section of the round rod segment 21 is set to be circular. The placement mechanism 3 includes a rotating platform 31 and a placement platform 32. The rotating platform 31 is rotatably mounted on the round rod segment 21 of the support rod 2. The outer peripheral surface of the rotating platform 31 is provided with a sliding groove 311. The opening direction of the sliding groove 311 is the same as the axis direction of the rotating platform 31, and the sliding groove 311 passes through the top surface of the rotating platform 31. The placement platform 32 is slidably mounted on the outer peripheral side of the rotating platform 31. The inner side surface of the placement platform 32 is fixed with a sliding block 321. The shape of the sliding block 321 is the same as that of the sliding groove 311, so that the sliding block 321 can be matched and slidably installed inside the sliding groove 311.

[0043] Reference Figure 5A first spring 33 is disposed between the placement platform 32 and the rotating platform 31. The first spring 33 is located within the sliding slot 311. One end of the first spring 33 abuts the inner bottom wall of the sliding slot 311, and the other end abuts the sliding block 321. The first spring 33 consistently exerts an elastic force on the sliding block 321, thereby constantly forcing the placement platform 32 upward. Furthermore, an abutment portion 422 protrudes from a portion of the inner wall of the placement platform 32. Under the elastic force of the first spring 33, the abutment portion 422 always partially abuts against the rotating platform 31, causing the placement platform 32 to be higher than the rotating platform 31.

[0044] Reference Figure 6 A limiting structure 4 is provided between the placing platform 32 and the support rod 2. When the support leg 6 is placed on the placing platform 32, the placing platform 32 and the support rod 2 can maintain circumferential positioning through the limiting structure 4; specifically, the limiting structure 4 includes a polygonal column sleeve 41 and a socket 42. The polygonal column sleeve 41 is fixedly sleeved on the round rod segment 21, and an anti-slip portion 23 is provided at one end of the round rod segment 21 away from the square rod segment 22. The outer diameter of the anti-slip portion 23 is larger than the outer diameter of the round rod segment 21; the spacing from the anti-slip portion 23 to the polygonal column sleeve 41 is equal to the axial length of the rotating platform 31, which can limit the movement of the rotating platform 31 along the axial direction of the support rod 2, so that the rotating platform 31 can only rotate circumferentially around the central axis of the round rod segment 21.

[0045] The socket 42 is fixedly connected to the bottom of the placement table 32, and a prismatic groove 421 is provided on the side of the socket 42 close to the support rod 2. Under the elastic force of the first spring 33, the prismatic groove 421 can be separated from the polygonal column sleeve 41. At this time, the rotating table 31 and the placement table 32 can rotate freely around the central axis of the round rod segment 21; and when the support leg 6 is placed on the socket 42, the weight of the support leg 6 acts on the placement table 32 to force the placement table 32 to move downward. At this time, the polygonal column sleeve 41 can match and abut against the inner wall of the prismatic groove 421, thereby limiting the rotation of the placement table 32 to achieve circumferential positioning of the placement table 32.

[0046] It should be noted here that the polygonal column sleeve 41 selected in this embodiment is a regular octagon, but in other feasible implementations, the shape of the polygonal column sleeve 41 can also be a regular hexagon, a regular decagon or a regular dodecagon, etc., and is not limited to the form shown in this embodiment.

[0047] In addition, back to Figure 5The side of the placement platform 32 away from the rotating platform 31 is provided with a stopper 322, which is integrally formed with the placement platform 32, and the top surface of the stopper 322 is higher than the top surface of the placement platform 32; the stopper 322 and the support rod 2 can be spaced apart to form a placement area for the support leg 6. After the support leg 6 is placed on the placement platform 32, the stopper 322 can protect the outer side of the support leg 6, which is used to reduce the possibility of the support leg 6 moving, flipping, and falling to the ground when a person accidentally touches the support leg 6 while walking, thereby reducing the possibility of a person being injured by the support leg 6 and reducing safety hazards.

[0048] The implementation principle of a support for grinding the legs of a forklift overhead guard according to an embodiment of the present application is as follows:

[0049] When the operator carries the leg 6 and places it on the placement table 32, the placement table 32 can be adjusted to the desired position by rotating the entire placement mechanism 3 around the central axis of the support rod 2. After the operator places the leg 6 on the placement table 32, the surface of the leg 6 to be polished is fully exposed, facilitating the polishing operation and reducing the operator's labor intensity. Furthermore, after the operator places the leg 6 on the placement table 32, the placement table 32 is subjected to the weight of the leg 6 and can maintain its circumferential position through the cooperation of the polygonal column sleeve 41 and the socket 42, thereby improving the operator's convenience in polishing the leg 6.

[0050] The above are preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
