Description

Technical Field

[0001] The utility model relates to the technical field of forklifts, in particular to a forklift which is convenient for adjusting the distance between fork rods. Background Art

[0002] A forklift is an industrial handling vehicle, specifically a wheeled handling vehicle that loads, unloads, stacks and transports palletized goods over short distances. The gantry system of a forklift is the lifting device of the forklift. In order to improve the stability and rigidity of the gantry, a double-link channel steel gantry is usually used.

[0003] After searching, the Chinese patent "A lifting device for a forklift mast" authorization announcement number "CN218202035U" uses a wedge plate and a second screw to lock the connection between the upper end of the fork rod and the lifting frame, which is convenient for flexible adjustment of the distance between the two fork rods without being restricted by the fixed hole position, so as to be suitable for transporting goods of different volumes.

[0004] Although the positions of the two fork rods can be adjusted in the above scheme, in order to ensure the stability of the forklift when transporting goods, the two fork rods need to be centered on the forklift. The above scheme needs to adjust the positions of the fork rods multiple times to achieve the centering of the two fork rods. This method of adjusting the distance between the two fork rods is too inconvenient. Utility Model Content

[0005] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the purpose of the utility model is to provide a forklift that is easy to adjust the distance between fork rods, so as to solve the problem that it is too inconvenient to adjust the distance between two fork rods in the prior art.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] An embodiment of the present application provides a forklift that facilitates adjusting the distance between fork rods, including: a forklift, an installation frame is slidably connected to the front end of the forklift, two movable blocks are slidably connected to the inner wall of the installation frame, and a fork rod is provided on one side of the movable block; an adjustment mechanism is provided inside the installation frame; wherein, the adjustment mechanism includes a sliding cylinder fixedly connected to the inner wall of the installation frame, a sliding rod is fixedly connected to one side of the movable block, the surface of the sliding rod is slidably connected to the inner wall of the sliding cylinder, the surface of the sliding cylinder is communicated with a first air pipe and a second air pipe, an air pump is fixedly connected to the top of the installation frame, one end of the air pump is communicated with a transfer frame, and one side of the transfer frame is respectively communicated with the first air pipe and the second air pipe. Through the air pump, the first air pipe and the second air pipe, when there is too much gas in the sliding cylinder, it is realized that the two sliding rods move simultaneously, and then the synchronous centering adjustment of the two fork rods is realized. Compared with the existing method of adjusting the distance between the two fork rods multiple times, the adjustment mechanism in this solution can quickly adjust the distance between the two fork rods at one time without multiple adjustments, making it more convenient to adjust the distance between the two fork rods and improving the practicability of the forklift.

[0008] In some embodiments, a first sealing frame and a second sealing frame are clamped at the openings of the first air pipe and the second air pipe, the upper ends of the surfaces of the first sealing frame and the second sealing frame are slidably connected to the inner wall of the transfer frame, racks are fixedly connected to one side of the first sealing frame and the second sealing frame, a gear is rotatably connected to the lower end of the surface of the transfer frame, and the opposite ends of the two racks are meshed and connected to the surface of the gear. Through the gear and the racks, it is realized that the first sealing frame and the second sealing frame move away from each other, so that the air inlet opening of the second air pipe and the air outlet opening of the first air pipe are opened simultaneously, and it is realized that the first sealing frame and the second sealing frame move closer to each other, so that the air outlet opening of the second air pipe and the air inlet opening of the first air pipe are opened simultaneously, which is convenient for adjusting the distance between the two fork rods.

[0009] In some embodiments, a servo motor is fixedly connected to the lower end of the surface of the transfer frame, and the output shaft of the servo motor is fixedly connected to one end of the gear.

[0010] In some embodiments, silica gel rings are fixedly connected to both ends of the inner wall of the sliding cylinder, and the surface of the sliding rod is slidably connected to the inner side of the silica gel rings. Through the silica gel rings, the connection between the sliding rod and the sliding cylinder is sealed to prevent air leakage in the sliding cylinder.

[0011] In some embodiments, rubber blocks are fixedly connected to both sides of the surfaces of the first sealing frame and the second sealing frame, and the surfaces of the rubber blocks are slidably connected to the inner wall of the transfer frame. Through the rubber blocks, the inner bottom wall of the transfer frame is sealed to prevent the gas in the transfer frame from flowing out through the opening of the inner bottom wall.

[0012] In some embodiments, three limiting rings are fixedly connected to the inner wall of the sliding cylinder. Through the limiting rings, the movement position of the sliding rod is restricted, preventing the surface end of the sliding rod from blocking the bottom openings of the first air pipe and the second air pipe, thereby affecting the movement of the sliding rod.

[0013] In some embodiments, two hydraulic cylinders are fixedly connected to the inner wall of the forklift, and the bottom ends of the hydraulic cylinders are fixedly connected to the top of the mounting frame. Through the hydraulic cylinders, the mounting frame and the fork rod can be stably lifted and lowered at the front end of the forklift, effectively preventing the entire vehicle, the electric control box or the body structure above from being lifted synchronously after the lifting device is lifted and lowered, and reducing the influence of the shaking and variation of the vehicle body within the lifting and lowering range on the accuracy of the upper and lower laser calibration and positioning.

[0014] In some embodiments, two bolts are threadedly connected to the inner wall of the movable block, and the surface of the bolts is threadedly connected to the inner wall of the fork rod. Through the bolts, the fork rod can be quickly installed on the mounting frame, and the operation of installing the fork rod on the forklift is simple.

[0015] Compared with the prior art, the present utility model has at least the following beneficial effects:

[0016] A forklift provided by an embodiment of the present application that is convenient for adjusting the distance between fork rods realizes the simultaneous movement of two sliding rods by the excessive gas in the sliding cylinder through an air pump, a first air pipe and a second air pipe, and further realizes the synchronous centering adjustment of the two fork rods. Compared with the prior art of adjusting the distance between the two fork rods multiple times, the adjusting mechanism in this solution can quickly adjust the distance between the two fork rods at one time without multiple adjustments, making it more convenient to adjust the distance between the two fork rods and improving the practicability of the forklift.

[0026] In the description of the present utility model, when it is described that a specific device is located between a first device and a second device, there may or may not be an intermediate device between the specific device and the first device or the second device. When it is described that a specific device is connected to other devices, the specific device may be directly connected to the other devices without an intermediate device, or may not be directly connected to the other devices but have an intermediate device.

[0027] For technologies, methods, and devices known to those of ordinary skill in the relevant fields, they may not be discussed in detail, but under appropriate circumstances, the said technologies, methods, and devices should be regarded as part of the specification.

[0028] Refer to Figures 1 to 4, this embodiment provides a forklift truck that facilitates adjusting the distance between fork rods, including: a forklift truck 1, with a mounting frame 2 slidably connected to the front end of the forklift truck 1. There are two movable blocks 3 slidably connected to the inner wall of the mounting frame 2, and a fork rod 4 is provided on one side of the movable block 3; an adjustment mechanism 5, which is arranged inside the mounting frame 2; among them, the adjustment mechanism 5 includes a sliding cylinder 51 fixedly connected to the inner wall of the mounting frame 2. A sliding rod 52 is fixedly connected to one side of the movable block 3, and the surface of the sliding rod 52 is slidably connected to the inner wall of the sliding cylinder 51. The surface of the sliding cylinder 51 is communicated with a first air pipe 53 and a second air pipe 54. A pneumatic pump 56 is fixedly connected to the top of the mounting frame 2, and one end of the pneumatic pump 56 is communicated with a transfer frame 55. One side of the transfer frame 55 is respectively connected to the first air pipe 53 and the second air pipe 54.

[0029] An electric control box is installed on the surface of the forklift truck 1. A multi-line lidar is provided on the top of the electric control box, and a double-horn laser is provided at the lower end of the surface of the electric control box. One end of the surface of the sliding rod 52 is a rubber component, and one end of the surface of the sliding rod 52 closely adheres to the inner wall of the sliding cylinder 51 to prevent air leakage between the sliding rod 52 and the sliding cylinder 51. Both the first seal frame 57 and the second seal frame 58 are silicone rubber components. The mounting frame 2, the movable block 3, and the fork rod 4 are all steel components.

[0030] When it is necessary to adjust the distance between the two fork rods 4, drive the first seal frame 57 and the second seal frame 58 to move away from each other, so that the air inlet opening of the second air pipe 54 and the air outlet opening of the first air pipe 53 are opened simultaneously, and the air outlet opening of the second air pipe 54 and the air inlet opening of the first air pipe 53 are blocked simultaneously. Manually turn on the pneumatic pump 56. The pneumatic pump 56 compresses the external gas and transports it into the transfer frame 55. The gas in the transfer frame 55 flows into the sliding cylinder 51 through the air inlet opening of the second air pipe 54. Excessive gas in the sliding cylinder 51 pushes the two sliding rods 52 to move away from each other. During the movement of the sliding rod 52, the gas at one end of the inner wall of the sliding cylinder 51 is pushed out through the air outlet opening of the first air pipe 53. The movement of the sliding rod 52 drives the movable block 3 to move, and the movement of the movable block 3 drives the fork rod 4 to move to an appropriate position. Manually turn off the pneumatic pump 56 to quickly and synchronously adjust the positions of the two fork rods 4 on the mounting frame 2. At this time, start the forklift truck 1 to transport the goods on the pallet to the corresponding location.

[0031] As Figure 4 shown, the openings of the first air pipe 53 and the second air pipe 54 are clamped with a first seal frame 57 and a second seal frame 58. The upper ends of the surfaces of the first seal frame 57 and the second seal frame 58 are slidably connected to the inner wall of the transfer frame 55. A rack 510 is fixedly connected to one side of both the first seal frame 57 and the second seal frame 58. A gear 59 is rotatably connected to the lower end of the surface of the transfer frame 55. The opposite ends of the two racks 510 are meshed with the surface of the gear 59. A servo motor 511 is fixedly connected to the lower end of the surface of the transfer frame 55, and the output shaft of the servo motor 511 is fixedly connected to one end of the gear 59.

[0032] Manually turn on the servo motor 511. The output shaft of the servo motor 511 rotates to drive the gear 59 to rotate. The rotation of the gear 59 drives the two racks 510 to move away from each other, causing the first seal frame 57 and the second seal frame 58 to move away from each other.

[0033] As Figure 3 shown, silicone rubber rings 513 are fixedly connected to both ends of the inner wall of the sliding cylinder 51. The surface of the sliding rod 52 is slidably connected to the inside of the silicone rubber ring 513. Rubber blocks 512 are fixedly connected to both sides of the surfaces of the first seal frame 57 and the second seal frame 58. The surface of the rubber block 512 is slidably connected to the inner wall of the transfer frame 55.

[0034] As Figure 3 shown, three limiting rings 514 are fixedly connected to the inner wall of the sliding cylinder 51.

[0035] As Figure 2 shown, two hydraulic cylinders are fixedly connected to the inner wall of the forklift 1. The bottom ends of the hydraulic cylinders are fixedly connected to the top of the mounting frame 2.

[0036] As Figure 3 shown, two bolts are threadedly connected to the inner wall of the movable block 3. The surface of the bolts is threadedly connected to the inner wall of the fork rod 4.

[0037] Compared with the prior art, the above embodiment provides a forklift that is convenient for adjusting the distance between fork rods. Manually turn on the servo motor 511. The output shaft of the servo motor 511 rotates to drive the gear 59 to rotate. The rotation of the gear 59 drives the two racks 510 to move away from each other, causing the first seal frame 57 and the second seal frame 58 to move away from each other, simultaneously opening the air inlet opening of the second air pipe 54 and the air outlet opening of the first air pipe 53, and simultaneously blocking the air outlet opening of the second air pipe 54 and the air inlet opening of the first air pipe 53. Manually turn on the air pump 56. The air pump 56 compresses the outside air and transports it into the transfer frame 55. The air in the transfer frame 55 flows into the sliding cylinder 51 through the air inlet opening of the second air pipe 54. Excessive air in the sliding cylinder 51 pushes the two sliding rods 52 to move away from each other. During the movement of the sliding rod 52, the air at one end of the inner wall of the sliding cylinder 51 is pushed out through the air outlet opening of the first air pipe 53. The movement of the sliding rod 52 drives the movable block 3 to move. The movement of the movable block 3 drives the fork rod 4 to move to a suitable position. Manually turn off the air pump 56 to quickly and synchronously adjust the positions of the two fork rods 4 on the mounting frame 2. Manually turn on the hydraulic cylinder. The hydraulic cylinder drives the mounting frame 2, the fork rod 4, and the pallet to move up smoothly to a suitable height. Manually turn off the hydraulic cylinder. At this time, start the forklift 1 to carry the goods on the pallet to the corresponding location.

[0038] It should be noted that in the above description, hydraulic cylinders, bolts, forklifts 1, installation frames 2, fork rods 4, air pumps 56, servo motors 511, etc. are all devices with relatively mature applications in the prior art. Specific models can be selected according to actual needs. At the same time, the power supply for hydraulic cylinders, forklifts 1, air pumps 56, and servo motors 511 can be an internal power supply or a mains power supply. The specific power supply method is selected according to the situation and will not be elaborated here.

[0039] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as within the scope described in this specification.

[0040] The above embodiments only represent several implementation modes of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
