[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1 , Figure 2 As shown, a forklift load-bearing capacity testing device includes: a testing platform 1 for parking the forklift, with a recessed equipment pit 11 at the front end of the testing platform 1; two fork sleeves 2 slidably connected to the testing platform 1; a first load box 3 disposed on the testing platform 1, positioned above the fork sleeves 2; a second load box 4 disposed within the equipment pit 11; a plurality of load blocks 5 disposed within the second load box 4; a connecting rod 6 penetrating the load blocks 5, with the top of the connecting rod 6 connected to the fork sleeves 2; and a pin 7 connecting the connecting rod 6 and the load blocks 5.

[0024] The fork sleeve 2 has holes. When testing the load-bearing capacity of the forklift, the forks are inserted into the fork sleeve 2 for testing. The testing platform 1 is equipped with a first slide rail 12. The rear end of the fork sleeve 2 is slidably connected to the first slide rail 12. The distance between the two fork sleeves 2 is adjusted by the power provided by the forklift to the forks. When adjusting the distance, it is ensured that the rear end of the fork sleeve 2 is in contact with the first slide rail 12. The first slide rail 12 restricts the horizontal movement direction of the fork sleeve 2. The load-bearing capacity can be tested under different distances between the two forks by moving the fork sleeve 2.

[0025] A second slide rail 111 is provided in the pit 11 of the equipment. A vertical rod 112 is slidably connected to the second slide rail 111. The second slide rail 111 is parallel to the first slide rail 12. The second slide rail 111 restricts the movement direction of the vertical rod 112. The vertical rod 112 passes through the front side wall of the fork sleeve 2. When the fork sleeve 2 moves, it drives the vertical rod 112 to slide along the second slide rail 111. The vertical rod 112 is used to restrict the vertical movement path of the fork sleeve 2. The height of the vertical rod 112 is greater than the maximum lifting height of the forklift.

[0026] The first load cell 3 is equipped with a counterweight, the weight of which is the minimum load capacity of the forklift. A support block 31 is located at the bottom of the first load cell 3, and an extension plate 32 is located on the bottom side wall of the first load cell 3. When the support block 31 contacts the testing platform 1, the extension plate 32 is positioned above the fork sleeves 2. Before lifting, the fork sleeves 2 are not in contact with the first load cell 3, facilitating adjustment of the distance between the two fork sleeves 2. During lifting, the forks move the fork sleeves 2 upwards, thereby lifting the first load cell 3. This process verifies whether the basic performance of the forklift is up to standard.

[0027] The second load box 4 is located on both sides of the equipment pit 11. The bottom of the second load box 4 is fixed to the bottom surface of the equipment pit 11. The second load box 4 restricts the position of the load block 5. The top surface of the second load box 4 is located below the bottom surface of the fork sleeve 2, thereby avoiding the fork sleeve 2 from colliding with the side wall of the second load box 4 when moving left and right. The side wall of the second load box 4 facing the fork sleeve 2 is provided with a notch 41. The width of the notch 41 is smaller than the width of the load block 5, thereby preventing the load block 5 from slipping off the notch 41 during use.

[0028] like Figure 3 As shown, the second load cell 4 is equipped with two limiting rods 42, which are fixed to and pass through the side wall of the second load cell 4. The limiting rods 42 are at the same height as the vertical rod 112. The load block 5 can be lifted to the top of the limiting rods 42. The side of the load block 5 is provided with a positioning groove 51, which is slidably connected to the limiting rods 42. The two limiting rods 42 can restrict the rotation of the load block 5, and the load block 5 will also maintain vertical movement after being lifted above the second load cell 4.

[0029] Several load blocks 5 are placed together in the second load box 4. The middle of the load block 5 is provided with a vertical through hole 52, into which a connecting rod 6 can be inserted. The side of the load block 5 is provided with a horizontal through hole 53. The vertical through hole 52 is connected to the horizontal through hole 53. The vertical through hole 52 is located in the middle of the horizontal through hole 53. The outside of the horizontal through hole 53 is connected to a threaded sleeve 54. The middle of the threaded sleeve 54 is connected to the horizontal through hole 53.

[0030] The connecting rod 6 is provided with several connecting holes 61. The spacing between the connecting holes 61 is the same as the height of the load block 5. When the load block 5 is not lifted, the bottom of the connecting rod 6 is in contact with the bottom surface of the second load box 4. At this time, the connecting holes 61 and the horizontal through holes 53 are on the same straight line and connected. The diameter of the horizontal through holes 53 is less than or equal to the diameter of the connecting holes 61.

[0031] The top of the connecting rod 6 is connected to the side wall of the fork sleeve 2 by a steel strand 62. The steel strand 62 is equipped with two U-shaped locks at two points. The two U-shaped locks are respectively connected to the top of the connecting rod 6 and the side wall of the fork sleeve 2. The steel strand 62 has redundant length and can adapt to the left and right movement of the fork sleeve 2. When the fork sleeve 2 moves upward, it drives the connecting rod 6 to move together.

[0032] The pin 7 passes through the horizontal through hole 53 and the connecting hole 61. The tail end of the pin 7 is equipped with a screw 71, which can be screwed onto the threaded sleeve 54. The screw 71 and threaded sleeve 54, when screwed together, restrict the position of the pin 7. When additional counterweight is needed for the forklift, the pin 7 is inserted into the corresponding load block 5, passing through the connecting hole 61. When the connecting rod 6 moves upward, it causes the pin 7 to move upward as well. The pin 7 then moves the load block 5 it is inserted into, along with the upper load block 5, upward. The lower load block 5 does not participate in the counterweight. By gradually increasing the counterweight of the load blocks 5, the load-bearing capacity of the forklift can be detected. The load-bearing capacity can be quickly measured by rapidly changing the number of load blocks 5. Simultaneously, the load weight on both sides can be changed by inserting different load blocks 5, thereby detecting the load-bearing capacity of the forklift under eccentric conditions.

[0033] The testing platform 1 is equipped with a weighbridge 13. The rear wheels of the forklift are placed on the weighbridge 13. The weight measured by the weighbridge 13 can be displayed in real time. When the forklift is lifting the load, if the weight displayed by the weighbridge 13 on the rear wheels is zero, it indicates that the forklift is tilting forward severely. At this time, the load is at its maximum bearing capacity.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
