Description

Technical Field

[0001] The present invention relates to the technical field of forklift components, and in particular to a controllable shock-absorbing circumferential side fastening forklift frame. Background Art

[0002] Forklifts are industrial handling vehicles, various wheeled vehicles used for loading, unloading, stacking, and short-distance transport of palletized cargo. They are widely used in ports, stations, airports, freight yards, factory workshops, warehouses, distribution centers, and distribution centers, performing loading, unloading, and transporting of palletized cargo within ship cabins, train compartments, and containers. They are essential equipment for pallet and container transport.

[0003] The forklift frame is a connecting component on the lifter at the front end of the forklift. Its main function is to be driven by the lifter to lift and transport goods.

[0004] According to the above, the forklift frame in the existing technology has a relatively simple structure. Although it can be driven by the lifter to lift and transport goods, it generally has the following defects:

[0005] 1. During the lifting process, the lack of clamping and fastening measures can easily lead to sliding and sliding, which is not conducive to maintaining a stable height after lifting to a certain height.

[0006] 2. When the forklift is in motion, vibration and shaking are easily transmitted to the fork plate, which causes the goods to shake significantly during forklift transportation, and even cause the goods to fall.

[0007] Therefore, in view of the above defects, it is necessary to design a forklift frame with a regulated and damped circumferential side fastening. Summary of the Invention

[0008] The technical problem to be solved by the present invention is to provide a forklift frame with adjustable shock absorption and peripheral side fastening to solve the problems raised by the background technology.

[0009] The cam is fixed on the upper part of the fixing frame, and the cam is fixed on the lower part of the fixing frame, and the cam is fixed on the lower part of the fixing frame. The left and right sides of the sleeve are connected by sliding left and right, the push column is slidably arranged at the left and right ends of the fixed sleeve, the push column and the fixed sleeve are connected by sliding left and right, and the push column and the wedge block are connected by welding, the outer cover is fixed on the left and right sides of the bottom of the fixed frame, the outer cover and the fixed frame are integrally formed, the number of guide columns is several, the guide column is fixed inside the outer cover from front to back, the guide column and the outer cover are connected by welding, the first spring is sleeved on the upper end of the outer wall of the guide column, the first spring and the guide column are connected by sliding up and down, and the top end of the first spring and the outer cover are connected by welding, the second spring is sleeved on the lower end of the outer wall of the guide column, the second spring and the guide column are connected by sliding up and down, and the bottom end of the second spring and the outer cover are connected by welding, the fork plate is slidably arranged inside the outer cover, the fork plate and the outer cover are connected by sliding up and down, and the fork plate and the guide column are connected by sliding up and down.

[0016] Compared with the existing technology, this type of forklift frame with adjustable shock absorption and peripheral side fastening has the following advantages:

[0019] 3. The fork plate can directly transport the goods. With the cooperation of several first springs at the upper end and several second springs at the lower end, the fork plate can slide up and down along the guide column for buffering, thereby achieving the purpose of shock absorption and improving the stability during fork transportation.

[0027] The following specific implementation manner will be further described in conjunction with the above-mentioned drawings. DETAILED DESCRIPTION

[0028] In the following text, numerous specific details are set forth in order to provide a thorough understanding of the concepts that form the basis of the described embodiments; however, it will be apparent to those skilled in the art that the described embodiments may be practiced without some or all of these specific details. In other instances, well-known processing steps are not specifically described.

[0029] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 As shown, a controllable shock-absorbing circumferential side fastening forklift frame includes a fixing frame 1, a threaded sleeve 2, a fixed shaft 3, a rotating plate 4, a fixing sleeve 5, an electric push rod 6, a trapezoidal block 7, a wedge block 8, a push column 9, an outer cover 10, a guide column 11, a first spring 12, a second spring 13, a fork plate 14, an auxiliary sliding sleeve 101, an avoidance hole 102, a clamping plate 401, an avoidance cavity 501, a spring 801, and an anti-slip groove 1401;

[0030] In one embodiment, the inner wall of the threaded sleeve 2 is a threaded structure, which can be inserted into the screw rod on the front lifter of the forklift in the prior art, and driven by the motor on the lifter to rotate, and synchronously cooperate with the auxiliary sliding sleeve 101 and the limit posts on both sides of the lifter to achieve the purpose of lifting the forklift frame up and down;

[0031] In one embodiment, the fixed shaft 3 limits the rotating plate 4, facilitating the rotating plate 4 to rotate about the fixed shaft 3. At the same time, in conjunction with the clamping plate 401, the rotating plate 4 can be clamped laterally to both sides of the lifter in the prior art, thereby achieving lateral clamping and fixing, improving the stability of the forklift frame in a fixed state, and effectively preventing the problem of sliding downward during the forklift transportation of goods.

[0032] In one embodiment, the electric push rod 6 can drive the trapezoidal block 7 to extend and retract up and down. When the trapezoidal block 7 descends, it can push the wedge blocks 8 on both sides to drive the push posts 9 to slide outward, that is, the push posts 9 overcome the rebound force of the spring 801 to push the rotating plate 4 outward to rotate, which is beneficial for the rotating plate 4 to drive the clamping plate 401 to perform the lateral clamping purpose. When it is necessary to cancel the lateral clamping force, the electric push rod 6 drives the trapezoidal block 7 to slide upward, canceling the push on the wedge block 8. Under the action of the rebound force of the spring 801, the wedge block drives the push posts 9 to retract into the avoidance cavity 501 inside the fixed sleeve 5, and finally achieves the purpose of canceling the push on the rotating plate 4;

[0033] In one embodiment, the fork plate 14 can directly carry goods for forklift. During the forklift process, the first springs 12 at the upper end and the second springs 13 at the lower end cooperate with each other to facilitate the fork plate 14 to slide up and down along the guide column 11 for buffering, thereby achieving the purpose of shock absorption and improving the stability during forklift. At the same time, the anti-slip groove 1401 can also increase friction, effectively preventing the problem of goods slipping off the fork plate 14.

[0034] Specifically, first, during installation, the fixing frame 1 is sleeved on the outside of the lifter in the prior art, the threaded sleeve 2 is sleeved on the outer wall of the screw rod, the auxiliary sliding sleeve 101 is sleeved on the outer wall of the limit column, and the electric push rod 6 is electrically connected to the lifter control system of the forklift; secondly, during operation, when the control system of the lifter receives the lifting command given by the driver, it controls the electric push rod 6 in advance, which is conducive to the upward retraction of the electric push rod 6, that is, canceling the push on the rotating plate 4, which is conducive to the rotating plate 4 being released, and is conducive to the subsequent lifter motor driving the screw rod to drive the forklift frame to move up and down. When the lifter is lifted to the specified position and stops working, the control system of the lifter controls the electric push rod 6 again Control is performed to realize that the electric push rod slides downward, that is, the rotating plate 4 drives the clamping plate 401 to re-clamp the lifter. At this time, the above operation can not only realize lateral clamping and fixation, and improve the stability of the forklift frame in a fixed state, but also does not affect the normal lifting operation of the forklift frame driven by the lifter; finally, when the fork plate 14 forks the goods, because the forklift is prone to shaking during driving, the fork plate 14 drives the goods to shake greatly, and then with the help of the outer cover 10, the guide column 11, the first spring 12 and the second spring 3, shock absorption and buffering are realized, which reduces the possibility of large-scale shaking of the goods, and ultimately greatly improves safety and stability.

[0035] The present invention is not limited to the above-mentioned specific implementation methods. Various changes made by ordinary technicians in this field based on the above-mentioned concept without creative work are all within the scope of protection of the present invention.
