Description

Technical Field

[0001] This utility model relates to the field of logistics equipment manufacturing technology, specifically to a pre-assembly device for an electric forklift without a tailstock. Background Technology

[0002] In existing technologies, the pre-assembly of the frame of a tailstock-less electric forklift typically uses a simple ground-based support structure. However, this method has significant limitations: during the installation of the counterweight, operators need to frequently enter under the forklift to adjust and change the position of the support frame to adapt to the needs of different processes. This manual operation not only increases the difficulty and labor intensity of the work but also easily leads to deviations in the installation position, thus adversely affecting product quality.

[0003] Furthermore, the efficiency of the entire operation is significantly constrained by the need to repeatedly change the position of the support frame during installation. Frequent manual operations not only increase production time but also pose certain safety hazards, such as the potential risks of accidents caused by personnel working under the vehicle. Therefore, the existing chassis pre-assembly device lacks targeted optimization and cannot meet the requirements of modern production for high efficiency and high quality. Utility Model Content

[0004] The purpose of this utility model is to provide a pre-installation device for electric forklifts without tailstocks, thereby solving the problems existing in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pre-assembly device for a tailstock-less electric forklift, comprising:

[0006] Supporting institutions;

[0007] A sliding mechanism that can slide on a support mechanism;

[0008] An adjustment mechanism is provided on the sliding mechanism, and the adjustment mechanism is used to adjust the position of the sliding mechanism;

[0009] A first limiting mechanism is mounted on the support mechanism;

[0010] The second limiting mechanism is mounted on the support mechanism and is used to limit the sliding of the sliding mechanism.

[0011] Preferably, the support mechanism includes multiple base legs, with a base plate fixedly connected to the bottom of each base leg, a channel steel rail fixedly connected to the top of each base leg, and a channel steel sealing plate fixed to the end of each channel steel rail.

[0012] Preferably, the first limiting mechanism includes a limiting plate base plate, the limiting plate base plate is fixed to the top of the channel steel rail, and a limiting plate is fixedly connected to the top of the limiting plate base plate.

[0013] Preferably, the second limiting mechanism includes a limiting bolt, which is fixedly connected to the end of the channel steel track away from the limiting plate.

[0014] Preferably, the sliding mechanism includes a sliding base plate, a plurality of supporting square tubes are fixedly fixed to the top of the sliding base plate, two roller mounting plates are fixedly connected to the bottom of the sliding base plate, rollers are rotatably connected to the roller mounting plates, and a reinforcing rib plate is fixedly connected between the roller mounting plates and the sliding base plate.

[0015] Preferably, the roller slides on the channel steel track.

[0016] Preferably, the adjustment mechanism includes a rope adjustment hole disposed on the sliding base plate, the rope adjustment hole being used to adjust the position of the sliding base plate on the channel steel track by means of a rope.

[0017] Preferably, the rope adjustment hole is located at the center of the sliding base plate.

[0018] Preferably, the top of the supporting square tube is provided with an anti-slip pad.

[0019] As can be seen from the above technical solution, this utility model has the following beneficial effects:

[0020] This pre-assembly device for the tailstock-less electric forklift utilizes a sliding mechanism and an adjustment mechanism. The sliding mechanism allows for flexible movement on the support structure, and its position is adjusted via ropes. This eliminates the need for frequent manual entry under the vehicle to change the frame position, significantly improving the efficiency of frame pre-assembly. The adjustment mechanism features rope adjustment holes, allowing operators to easily adjust the sliding mechanism's position from outside the frame, avoiding the high-intensity work of repeatedly entering under the vehicle as in traditional methods and improving working conditions. The sliding mechanism is equipped with reinforcing ribs and anti-slip pads to ensure frame stability during sliding and installation, preventing damage caused by positional deviations. To address assembly quality issues and improve product quality, the sliding mechanism's movement range is limited by first and second limit mechanisms. In particular, the use of limit bolts effectively prevents the sliding mechanism from derailing. Simultaneously, the adjustment mechanism, operated via ropes, avoids potential safety hazards associated with personnel working under the vehicle. The adjustable support structure meets the pre-assembly requirements of tailstock-less electric forklift frames of different tonnages (1-3.8 tons), demonstrating wide applicability. The support mechanism employs a channel steel rail design, allowing the sliding mechanism to slide smoothly along the rail. Furthermore, the position of the support square tube can be flexibly adjusted according to the frame size, satisfying diverse assembly process requirements. Attached Figure Description

[0026] 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.

[0027] like Figure 1-Figure 4 As shown, this utility model provides a technical solution: a pre-assembly device for an electric forklift without a tailstock, comprising: a support mechanism 1; a sliding mechanism 2, which can slide on the support mechanism 1; an adjustment mechanism 3, which is disposed on the sliding mechanism 2 and is used to adjust the position of the sliding mechanism 2; a first limiting mechanism 4, which is disposed on the support mechanism 1; and a second limiting mechanism 5, which is disposed on the support mechanism 1 and is used to limit the sliding of the sliding mechanism 3.

[0028] The device provides a stable structural foundation through the support mechanism 1, allowing the sliding mechanism 2 to slide smoothly on the support mechanism 1. The position of the sliding mechanism 2 is adjusted by the adjusting mechanism 3 to achieve precise positioning of the forklift components. The first limiting mechanism 4 and the second limiting mechanism 5 respectively limit the movement range of the sliding mechanism 2 on the support mechanism 1, thereby ensuring the safety and reliability of the device. Compared with existing technologies, this device can more effectively realize the pre-assembly operation of tailstock-less electric forklifts, reduce manual adjustment errors, improve assembly efficiency, and at the same time provide necessary safety guarantees through the limiting mechanisms, enhancing the overall performance of the device.

[0029] The adjustment mechanism 3 can be replaced with an electric adjustment device to further improve the operation accuracy and convenience; the setting position and structural form of the first limit mechanism 4 and the second limit mechanism 5 can be adjusted according to specific needs, for example, a flexible limit design can be adopted to adapt to different types of sliding mechanisms.

[0030] In one possible implementation, the support mechanism 1 includes multiple base legs 11, with a base plate 12 fixedly connected to the bottom of each base leg 11 and a channel steel rail 13 fixedly connected to the top of each base leg 11. A channel steel end plate 14 is fixed to the end of each channel steel rail 13. The support mechanism 1 provides support through the base legs 11, the base plate 12 ensures the overall stability of the device, the channel steel rail 13 provides a sliding path for the sliding mechanism, and the channel steel end plate 14 prevents the sliding mechanism from slipping off the end of the rail. This design ensures the safety and reliability of the device during use. The channel steel rail design not only provides high-strength support but also allows the sliding mechanism to move more smoothly on the rail. Its cooperation with the base legs 11 and the base plate 12 further enhances the stability of the overall structure, effectively improving the service life and ease of operation of the device.

[0031] The number and size of the base legs 11 can be adjusted according to load requirements. The channel steel rail 13 can be made of other high-strength materials, such as aluminum alloy, to reduce the overall weight. The channel steel end plate 14 can be replaced with a detachable end cap structure to facilitate the maintenance and repair of the device.

[0032] In one possible implementation, the first limiting mechanism 4 includes a limiting plate base plate 41, which is fixed to the top of the channel steel rail 13. A limiting plate 42 is fixedly connected to the top of the limiting plate base plate 41. The first limiting mechanism 4 provides stable support through the connection between the limiting plate base plate 41 and the channel steel rail 13. The limiting plate 42 serves as a physical limiting device for the sliding mechanism, preventing the sliding mechanism from exceeding its predetermined movement range. By setting the limiting plate base plate 41 and the limiting plate 42, not only can the movement accuracy of the sliding mechanism be ensured, but also necessary safety protection can be provided in case of unexpected events, significantly reducing the risk of the sliding mechanism derailing.

[0033] The limiting plate base plate 41 can be fixed by an adjustable bolt connection so that the limiting position can be adjusted as needed; the limiting plate 42 can be replaced by an elastic limiting structure to better absorb the impact force of the sliding mechanism.

[0034] In one possible implementation, the second limiting mechanism 5 includes a limiting bolt 51, which is fixedly connected to the end of the channel steel rail 13 away from the limiting plate 42. Through the fixing action of the limiting bolt 51, the second limiting mechanism 5 acts as a stop when the sliding mechanism moves to the end of the channel steel rail, further ensuring that the sliding range of the sliding mechanism remains within a controllable range. The limiting bolt 51 has a simple structure, is easy to adjust, effectively protects the device from excessive movement of the sliding mechanism, and is also inexpensive, easy to manufacture, and easy to replace.

[0035] The limit bolt 51 can be replaced with a flexible stop device, such as a rubber buffer block, to reduce the impact force on the device structure.

[0036] In one possible implementation, the sliding mechanism 2 includes a sliding base plate 21. Multiple supporting square tubes 22 are fixed to the top of the sliding base plate 21, and two roller mounting plates 23 are fixedly connected to the bottom of the sliding base plate 21. Rollers 24 are rotatably connected to the roller mounting plates 23, and reinforcing ribs 25 are fixedly connected between the roller mounting plates 23 and the sliding base plate 21. The sliding base plate 21 provides the main support surface for the sliding mechanism, and the supporting square tubes 22 further enhance the structural strength of the device and can be used to connect other additional components. The roller mounting plates 23 and rollers 24 cooperate to achieve smooth sliding of the sliding mechanism on the channel steel track 13, while the reinforcing ribs 25 increase the overall rigidity of the sliding mechanism and prevent deformation during use. Through this modular design, the sliding mechanism is compact and easy to assemble. The use of rollers 24 reduces frictional resistance during sliding, improving operational efficiency and stability. Simultaneously, the design of the reinforcing ribs 25 enhances the load-bearing capacity of the device, enabling it to withstand larger loads.

[0037] The material of the rollers 24 can be changed according to the specific application scenario. For example, nylon rollers can be used to reduce noise, or metal rollers can be used to improve wear resistance. The thickness and shape of the reinforcing ribs 25 can also be adjusted according to load requirements to optimize the rigidity-to-weight ratio.

[0038] In one possible implementation, the roller 24 slides on the channel steel rail 13. The roller 24 rolls on the inner surface of the channel steel rail 13, causing the sliding mechanism to move along the rail direction. The precise fit between the roller 24 and the channel steel rail 13 ensures smooth sliding and avoids lateral swaying. The sliding structure design of the roller 24 on the channel steel rail 13 reduces friction during sliding, lowers equipment energy consumption, and ensures precise and controllable movement direction of the sliding mechanism. The inner surface of the channel steel rail 13 can be coated or padded to reduce rolling friction, and the diameter and width of the roller 24 can be adjusted according to the rail dimensions to adapt to different application scenarios.

[0039] In one possible implementation, the adjustment mechanism 3 includes a rope adjustment hole 31 disposed on the sliding base plate 21. The rope adjustment hole 31 is used to adjust the position of the sliding base plate 21 on the channel steel rail 13 via a rope. The rope passes through the rope adjustment hole 31 and is connected to the sliding base plate 21. By pulling or loosening the rope, the precise position adjustment of the sliding base plate 21 along the channel steel rail 13 can be achieved, thereby meeting the diverse needs of forklift pre-assembly operations. This adjustment mechanism has a simple structure, flexible operation, and facilitates quick adjustment of the sliding mechanism position by the user, making it suitable for various working conditions. Furthermore, the design of the rope adjustment hole 31 makes fixing and operating the sliding mechanism in different positions more convenient.

[0040] The arrangement of the rope adjustment hole 31 can be optimized as needed, for example, by using a multi-hole design to accommodate more adjustment schemes. The adjustment method can also be replaced with a rack and pinion drive or a hydraulic adjustment device to achieve higher precision control.

[0041] In one possible implementation, the rope adjustment hole 31 is located at the center of the sliding base plate 21. Positioning the rope adjustment hole 31 at the center of the sliding base plate 21 ensures uniform force distribution during rope adjustment, avoiding tilting of the sliding base plate 21 and uneven force distribution, thereby improving the accuracy and reliability of the adjustment operation. The centrally located rope adjustment hole 31 optimizes force distribution, simplifies operation steps, and improves the stability of the device, making the adjustment of the sliding mechanism smoother and more efficient. The position of the rope adjustment hole 31 can be slightly offset according to actual usage requirements; for example, additional adjustment holes can be provided on the side of the sliding base plate 21 to provide a more flexible adjustment method.

[0042] In one possible implementation, an anti-slip pad is provided on the top of the supporting square tube 22. The anti-slip pad, fixed to the top of the supporting square tube 22, effectively increases friction, preventing the device from sliding or shifting during heavy loads or vibration, thus ensuring operational safety. The anti-slip pad not only improves the stability of the device during use but also reduces the risk of accidents caused by sliding heavy loads, while extending the device's service life. The anti-slip pad can be made of different materials, such as silicone pads to increase softness or rubber pads to enhance wear resistance. Furthermore, the shape and size of the anti-slip pad can be adjusted according to the specifications of the supporting square tube 22 to better match actual needs.

[0043] Working Process: Place the device in the assembly area and inspect the support mechanism 1 and sliding mechanism 2 to ensure that all components are in normal condition, especially the first limiting mechanism 4 and the second limiting mechanism 5, which are in a usable state. Precisely place the bottom crossbar of the electric forklift frame onto the end limiting portion of the support mechanism 1, i.e., the positions of the first limiting mechanism 4 and the second limiting mechanism 5. The physical constraint of the limiting portion ensures the initial stability of the frame on the device. Push the sliding mechanism 2 to the lower part of the forklift frame, aligning it with the frame position to prepare for the subsequent overall lowering and support of the frame. Carefully adjust the forklift frame so that it rests entirely on the sliding mechanism 2, ensuring structural compatibility between the frame and the sliding mechanism 2. At this point, the sliding mechanism 2 has good contact with the frame, and the frame is evenly stressed. With the support of the sliding mechanism 2 and the support mechanism 1, precisely install the counterweight of the electric forklift onto the upper part of the frame, completing the initial counterweight assembly operation. After assembly, slightly lift the counterweight to alleviate the supporting force on the frame. At this point, using the adjustment mechanism 3, the position of the sliding mechanism 2 is adjusted by pulling the rope adjustment hole 31 to optimize the distance between the frame and the counterweight. After adjustment, the entire frame, along with the counterweight, is slowly and completely placed on the sliding mechanism 2 and the support mechanism 1. The device continues to provide stable support for the frame for subsequent operations. With the frame stably placed on the device, the remaining internal piping of the forklift is installed and adjusted to ensure the correct connection and installation of all functional components. After the operation is completed, the assembled forklift frame is transferred from the device to the next workstation or production line using a hoisting device, thus completing the entire pre-assembly process.
