Description

Technical Field

[0001] The utility model relates to a battery bracket structure of a gantry forward-moving forklift and a forklift, belonging to the technical field of forklifts. Background Art

[0002] At present, the logistics and warehousing industry is gradually developing towards high-density storage. Therefore, reach forklifts with a small vehicle length can better meet the factory's use needs. At the same time, due to the long charging time, some manufacturers will choose to replace the battery to extend the operation time of the forklift. In order to reduce the length of the vehicle, the battery of the reach forklift will be hidden inside the vehicle body under normal use. When the battery needs to be replaced, the forward-moving gantry will drive the battery out of the frame, so the battery tray removal structure is very important.

[0003] An existing patent discloses a battery tray rack structure for a gantry-forward forklift (CN 106698268A), which includes a vehicle body, a battery tray, and a gantry. The battery tray is arranged between the gantry and the vehicle body, and the gantry and the vehicle body are connected by a slide rail. A two-way connecting device with two connecting parts is arranged on the battery tray, and the two connecting parts are respectively connected to the gantry and the vehicle body, and the connection state between the gantry and the connecting parts is opposite to that of the vehicle body. A pull rod and a non-contact switch for detecting the position of the two-way connecting device are arranged on the vehicle body, and the pull rod has a connection position for connecting to the connecting part and a loose position for loosening the connecting part. The above solution moves the battery tray out of the vehicle body, and realizes the locking function of the battery tray rack of the gantry forward forklift by plugging and pulling out the handle pin, and senses the battery position through a non-contact switch. However, since the hook is at the bottom of the vehicle, the switch needs to be installed and debugged before the assembly of the whole machine drive module, which is difficult to debug and replace later. At the same time, the pull rod only moves up and down, and the requirements for the accuracy of the relevant matching dimensions of each component are also very high, and the tooling manufacturing cost is high.

[0034] like Figure 1-Figure 7 As shown, a battery bracket structure of a mast forward-moving forklift includes a vehicle body 1, a battery tray 2 and a pulley 3;

[0035] The vehicle body 1 is provided with a reset link mechanism and a sensing switch 1-9, wherein the reset link mechanism comprises a slide bar 1-10 and a slide bar 2-12, and the sensing switch 1-9 is used to sense the position state of the slide bar 1-10;

[0036] The pulley 3 is connected to the vehicle body 1 via a slide rail, and a cylindrical shaft 3-2 is installed on the pulley 3;

[0037] The battery tray 2 is installed between the vehicle body 1 and the pulley 3. A reset hook 2-2 is installed on the battery tray 2. Both ends of the reset hook 2-2 are provided with hook parts with opposite opening directions. At the same time, the hook part is only unidirectionally connected and locked with one of the cylindrical shaft 3-2 or the slide rod 1-12.

[0038] As an improvement of the embodiment, Figure 2 As shown, the pulley 3 includes a pulley body 3-1, and the cylindrical shaft 3-2 is installed on the pulley body 3-1 through a nut, which is easy to install. The pulley body 3-1 is provided with a plurality of oblong holes 3-3 for installing the cylindrical shaft 3-2. The front and rear installation positions of the cylindrical shaft 3-2 on the pulley body 3-1 can be adjusted through the oblong holes 3-3, so as to adapt to the widths of various battery trays 2.

[0039] As an improvement of the embodiment, Figure 3-Figure 6 As shown, the battery tray 2 includes a tray body 2-1, a hook limit plate 2-3 is installed on the tray body 2-1, and the reset hook 2-2 is installed on the tray body 2-1 through a rotating shaft 2-7, and the reset hook 2-2 can rotate around the rotating shaft 2-7;

[0040] The first hook portion 2-6 at one end of the reset hook 2-2 is used to hook the sliding rod 1-12, and the second hook portion 2-8 at the other end is used to hook the cylindrical shaft 3-2. The hook limiting plate 2-3 is installed on one side of the reset hook 2-2 (located on the opening side of the second hook portion 2-8). The reset hook 2-2 and the hook limiting plate 2-3 are connected by a tension spring 2-4. When the first hook portion 2-6 of the reset hook 2-2 is unhooked from the sliding rod 1-12, the second hook portion 2-8 of the reset hook 2-2 is hooked to the cylindrical shaft 3-2 through the tension spring 2-4.

[0041] As an improvement of the embodiment, Figure 3 , Figure 4 As shown, a plurality of shock-absorbing blocks 2 - 5 are installed between the battery tray 2 and the vehicle body 1 , thereby improving the shock-absorbing performance between the battery tray 2 and the vehicle body 1 .

[0042] As an improvement of the embodiment, Figure 7 As shown, the reset link mechanism includes a handle fixing seat 1-2, a rotating handle 1-1, a connecting rod 1-4, a sliding rod 1-10, a sliding rod 2 1-12 and a sliding rod seat 1-5;

[0043] The handle fixing seat 1-2 is fixed on the upper part of the vehicle body 1, and the side wall of the slide bar seat 1-5 is installed on the lower part of the vehicle body 1 through bolts 1-11. The handle fixing seat 1-2, the rotating handle 1-1, the connecting rod 1-4, the slide bar 1-12 and the slide bar seat 1-5 constitute a connecting rod mechanism, and the slide bar 1-10 is movably installed in the slide bar seat 1-5.

[0044] Specifically, one end of the rotating handle 1-1 is rotationally connected to the handle fixing seat 1-2, and the other end is rotationally connected to the connecting rod 1-4 through the pin shaft 1-3. The connecting rod 1-4 is rotationally connected to the second sliding rod 1-12 through the pin shaft 1-3. The second sliding rod 1-12 is movably installed on the sliding rod seat 1-5. The upper and lower walls of the sliding rod seat 1-5 are provided with through holes. The second sliding rod 1-12 is limited by the upper and lower holes of the sliding rod seat 1-5, so that the second sliding rod 1-12 moves up and down along the sliding rod seat 1-5;

[0045] When the rotating handle 1-1 is rotated, the pin 1-3 is used to connect the rotating handle 1-1 and the connecting rod 1-4. The connecting rod 1-4 converts the rotation displacement of the rotating handle 1-1 into the up-and-down displacement of the second sliding rod 1-12, eliminating the left-right displacement generated during the rotation, and at the same time, it can also eliminate the installation position error between the rotating handle 1-1 and the second sliding rod 1-12. The second sliding rod 1-12 and the connecting rod 1-4 are also connected by the pin 1-3;

[0046] When the handle 1-1 is turned, the connecting rod 1-4 is pulled to move, and the connecting rod 1-4 pulls the sliding rod 1-12 to move. The sliding rod 1-12 is limited by the upper and lower holes of the sliding rod seat 1-5 and can only move up and down. The rotation displacement of the handle 1-1 is transmitted to the sliding rod 1-12 for up and down displacement through the connecting rod 1-4. At the same time, the upper side of the sliding rod 1-12 is installed with a compression spring 1-6 through an elastic cylindrical pin 1-7. The compression spring 1-6 is located on the inner side of the sliding rod seat 1-5. When the sliding rod 1-12 moves up, the compression spring 1-6 is between the sliding rod seat 1-5 and the elastic pin 1-7. The elastic cylindrical pins 1-7 are compressed; at the same time, a slide bar 1-10 arranged in parallel with the slide bar 2 1-12 is movably installed on the slide bar seat 1-5, and the slide bar 1-10 is also limited by the upper and lower holes of the slide bar seat 1-5, and can only move up and down. The upper side of the slide bar 1-10 is installed with a compression spring 2 1-8 through the elastic cylindrical pin 1-7, and the compression spring 2 1-8 is located on the inner side of the slide bar seat 1-5. Another elastic cylindrical pin 1-7 is installed on the lower side of the slide bar 1-10. The induction switch 1-9 is installed on the vehicle body 1 and is located above the slide bar 1-10;

[0047] When the first hook portion 2-6 of the reset hook 2-2 hooks the lower end of the slide bar 2-12 (the lower end of the slide bar 2-12 is exposed outside the bottom of the slide bar seat 1-5), the first hook portion 2-6 will simultaneously support and lift the lower end of the slide bar 1-10 (the lower end of the slide bar 1-10 is also exposed outside the bottom of the slide bar seat 1-5), so that the distance between the slide bar 1-10 and the induction switch 9 is close, ensuring that the signal can be connected, and the induction switch 1-9 senses the power, and then sends a battery in place signal. If the switch is damaged, the fault will be displayed;

[0048] When the handle 1-1 is turned to move the slide bar 1-12 upward, the lower end of the slide bar 1-12 moves upward and is unhooked from the first hook part 2-6, and the reset hook 2-2 moves under the action of the tension spring 2-4, causing the first hook part 2-6 and the second hook part 2-8 to rotate synchronously. At this time, the second hook part 2-8 is hooked with the cylindrical shaft 3-2, and the first hook part 2-6 is located below the slide bar 1-12, thereby preventing the slide bar 1-12 from falling. At the same time, the slide bar 1-10 falls (the elastic cylindrical pin 1-7 on its lower side can limit the falling distance), and the distance between the slide bar 1-10 and the induction switch 1-9 increases and disconnects the induction. The induction switch 1-9 sends a battery ejection signal to prevent the entire vehicle from moving and lifting.

[0049] In addition, if Figure 8 As shown, one side of the first hook portion 2-6 is provided with a bevel 2-9 and the other side is provided with a bevel arc edge 2-10, the bevel edge 2-9 is used for the slide bar 1-10 to move along the bottom to the top of the bevel edge, thereby triggering the induction switch 9; the bevel arc edge 2-10 is used for the lower end of the slide bar 2-12 to move along the outer side of the bevel arc edge 2-10 (such as Figure 8 The hook 2-6 is inserted into the notch of the first hook portion 2-6 (in the direction indicated by the middle arrow A).

[0050] Finally, the utility model also provides a forklift, on which the battery bracket structure of the gantry forward-moving forklift is installed.

[0051] When in use, the battery tray 2 can move back and forth through the slide rail on the vehicle body 1. When the reset hook 2-2 on the battery tray 2 hooks the vehicle body 1, the battery tray 2 cannot move, and the pulley 3 is driven by the cylinder to move along the slide rail of the vehicle body 1. When the pulley 3 is connected to the battery tray 2, the pulley 3 drives the battery tray 2 to move on the slide rail of the vehicle body 1. When it moves to the point where the reset hook 2-2 on the battery tray 2 is connected to the vehicle body 1, the inclined arc edge 2-10 of the first hook part 2-6 contacts with the slide bar 2 1-12 (at this time, the slide bar 2 1-12 has been pre-reset under the action of the compression spring 1-6), and the slide bar 2 1-12 causes the first hook part 2-6 to rotate to the notch of the first hook part 2-6 to clamp the slide bar 2 1-12. At the same time, the inclined edge 2-9 lifts the slide bar 1-10 to generate induction power with the induction switch 9; accordingly, the battery tray 2 and the pulley 3 are separated.

[0052] The battery bracket structure of the gantry forward-moving forklift of the utility model can flexibly adjust the installation position of the induction switch by only opening the hood without any disassembly, which is more convenient to operate, avoids moving the vehicle in a risky state, and is safer and more reliable.

[0053] In addition, those skilled in the art will understand that, although some embodiments described herein include certain features included in other embodiments but not other features, the combination of features of different embodiments also means being within the scope of protection of the present utility model and forming different embodiments. For example, in the above embodiments, those skilled in the art can use them in combination according to the known technical solutions and the technical problems to be solved by the present application.
