Description

Technical Field

[0001] This utility model relates to the field of pallet stacker technology, and in particular to a drive wheel pressurization and floating mechanism. Background Technology

[0002] Currently, pallet stacker trucks on the market generally come in two structural types: three-point and four-point. The advantages of a four-point structure are better overall vehicle stability and stronger resistance to lateral tipping; the disadvantage is that it's difficult to ensure all four points are in contact with the ground simultaneously. This often results in the drive wheels slipping and the vehicle becoming stuck. The advantage of a three-point structure is that it ensures three points are in contact with the ground simultaneously, but the overall stability of the vehicle is not as good.

[0003] To address the issue of insufficient stability in three-point structure vehicles, most pallet stackers with this structure on the market currently feature auxiliary support wheels on both sides of the drive wheels. To ensure a reasonable load-bearing distribution between the drive wheels and the auxiliary support wheels, the drive wheels are typically designed to be floating, with a pre-set value for the contact force between the drive wheels and the ground.

[0004] This pre-set contact force must ensure that the auxiliary support wheels can touch the ground when the vehicle is unloaded, and that the drive wheels have sufficient traction when the vehicle is fully loaded, thus giving the vehicle a certain climbing ability. However, this is a dilemma. To meet both conditions simultaneously, the vehicle's weight must be designed to be sufficiently heavy, which inevitably reduces the vehicle's climbing performance. Therefore, we propose a drive wheel pressurization and floating mechanism. Utility Model Content

[0005] The main purpose of this invention is to provide a booster floating mechanism for drive wheels, which can effectively solve the problem that in the prior art, floating drive wheels are designed to be sufficiently heavy to ensure that the auxiliary support wheels are on the ground when the vehicle is unloaded, while ensuring that the drive wheels and the ground have sufficient grip when the vehicle is fully loaded. However, this solution reduces the vehicle's climbing performance.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A drive wheel boosting floating mechanism includes a C-shaped mounting bracket with an upper mounting plate and a lower mounting plate. A boosting cylinder is fixedly mounted below the upper mounting plate of the C-shaped mounting bracket. A connecting plate is fixedly mounted below the telescopic rod of the boosting cylinder. A sleeve is fixedly mounted on one side of the connecting plate. A shaft head is sleeved inside the sleeve. A cam disc is fixedly mounted at a position slightly below the middle of the shaft head, and the lower end of the sleeve abuts against the cam disc. A mounting rod is fixedly mounted above the lower mounting plate of the C-shaped mounting bracket. A proximity switch sensor is fixedly mounted on the mounting rod, and the proximity switch sensor is flush with the cam disc.

[0008] Furthermore, an upper drive mounting bracket is fixedly mounted on one end of the upper mounting plate of the C-shaped mounting bracket, and a compression spring is fixedly mounted on the lower end of the upper drive mounting bracket. The lower end of the compression spring is fixedly mounted on the upper end of the sleeve, and the shaft head passes through the interior of the upper drive mounting bracket and the compression spring.

[0009] Furthermore, a lower drive mounting bracket is fixedly mounted on one end of the lower mounting plate of the C-shaped mounting bracket, and the shaft head passes through the interior of the lower drive mounting bracket.

[0010] Furthermore, a mounting plate is fixedly installed on the top of the shaft head, and an operating handle is fixedly installed on the mounting plate.

[0011] Furthermore, a mounting flange is fixedly installed at the bottom end of the shaft head, a drive assembly is provided below the mounting flange, and a drive wheel is provided on the drive assembly.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This utility model reduces vehicle weight and manufacturing costs by adding a booster cylinder to the floating mechanism of the drive wheel, improves the vehicle's climbing performance, and enables the auxiliary support wheel to touch the ground when the vehicle is unloaded without increasing its weight. When the vehicle is fully loaded, the drive wheel has sufficient grip on the ground. When the vehicle is fully loaded, the booster cylinder extends, the telescopic rod moves downward, driving the sleeve downward, pressing the cam plate and driving the axle head to press downward, thereby pressing the drive wheel tightly and ensuring sufficient grip on the ground. When the vehicle is unloaded without increasing its weight, the booster cylinder retracts, and the auxiliary support wheel can also touch the ground.

[0014] 2. This utility model, through the setting of a proximity switch sensor and a cam disk, when the operating handle is turned for turning adjustment, the shaft head will drive the cam disk to rotate. When the proximity switch sensor senses the change in the concavity and convexity on the cam disk, it detects the change in the turning signal and transmits the signal to the controller, thereby controlling the drive assembly to automatically decelerate. For vehicles with manual steering, it can greatly improve the vehicle's steering control, making the vehicle steering more comfortable and safe.

[0015] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

Detailed Implementation

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figure 1-4 As shown, the drive wheel boosting floating mechanism includes a C-shaped mounting bracket 1 with an upper mounting plate and a lower mounting plate. A boosting cylinder 2 is fixedly mounted below the upper mounting plate of the C-shaped mounting bracket 1. A connecting plate 3 is fixedly mounted below the telescopic rod of the boosting cylinder 2. A sleeve 4 is fixedly mounted on one side of the connecting plate 3. A shaft head 6 is sleeved inside the sleeve 4. A cam disk 5 is fixedly mounted at a lower position in the middle of the shaft head 6, and the lower end of the sleeve 4 abuts against the cam disk 5. A mounting rod 11 is fixedly mounted above the lower mounting plate of the C-shaped mounting bracket 1. A proximity switch sensor 12 is fixedly mounted on the mounting rod 11. The proximity switch sensor 12 is flush with the cam disk 5.

[0023] When using this application, if Figure 1 As shown, it is installed at the rear of the pallet stacker truck via a C-type mounting bracket 1, and is positioned between two auxiliary support wheels.

[0024] Specifically, when the vehicle is fully loaded, when the booster cylinder 2 extends, the telescopic rod moves downward, driving the sleeve 4 to move downward, pressing the cam disc 5 and driving the shaft head 6 to press downward as a whole, thereby pressing the drive wheel 10. The drive wheel 10 has sufficient grip on the ground. When the vehicle is unloaded without increasing its own weight, the booster cylinder 2 retracts, and the auxiliary support wheel can also touch the ground.

[0025] In another embodiment of this utility model, the proximity switch sensor 12 and the cam disk 5 are configured so that when the operating handle 13 is turned for turning adjustment, the shaft head 6 will drive the cam disk 5 to rotate. When the proximity switch sensor 12 senses the change in the concavity and convexity on the cam disk 5, it detects the change in the turning signal and transmits the signal to the controller, thereby controlling the drive assembly 16 to automatically decelerate.

[0026] The upper drive mounting bracket 7 is fixedly mounted on one end of the upper mounting plate of the C-type mounting bracket 1. A compression spring 8 is fixedly mounted on the lower end of the upper drive mounting bracket 7. The lower end of the compression spring 8 is fixedly mounted on the upper end of the sleeve 4. The shaft head 6 passes through the interior of the upper drive mounting bracket 7 and the compression spring 8.

[0027] The lower mounting plate of the C-type mounting bracket 1 is fixedly mounted with a lower drive mounting bracket 9 at one end, and the shaft head 6 passes through the interior of the lower drive mounting bracket 9.

[0028] The top of the shaft head 6 is fixedly mounted with a mounting plate 14, and an operating handle 13 is fixedly mounted on the mounting plate 14.

[0029] A mounting flange 15 is fixedly installed at the bottom end of the axle head 6. A drive assembly 16 is provided below the mounting flange 15. A drive wheel 10 is provided on the drive assembly 16. It should be noted that during installation, this utility model will be connected to the vehicle controller to realize the electrical connection between the drive assembly 16 and the controller. At the same time, the output end of the proximity switch sensor 12 is electrically connected to the input end of the controller. The specific drive assembly 16 is existing technology and is used to drive the drive wheel 10 to rotate.

[0030] It should be noted that this utility model is a drive wheel pressurization floating mechanism. In use, firstly, the device is installed at the rear of the pallet stacker truck through the C-type mounting bracket 1, and placed between the two auxiliary support wheels. When the vehicle is fully loaded, when the pressurization cylinder 2 extends, the telescopic rod moves downward, driving the sleeve 4 to move downward, pressing the cam disc 5 and driving the shaft head 6 to press downward as a whole, thereby achieving the pressing of the drive wheel 10. The drive wheel 10 has sufficient grip on the ground. When the vehicle is unloaded without increasing its own weight, the pressurization cylinder 2 retracts, and the auxiliary support wheel can also touch the ground.

[0031] When turning is required, the operating handle 13 is turned to adjust the turn. The shaft head 6 will drive the cam disk 5 to rotate. When the proximity switch sensor 12 senses the change in the concavity and convexity on the cam disk 5, it detects the change in the turning signal and transmits the signal to the controller, which in turn controls the drive assembly 16 to automatically decelerate, which is quite practical.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
