Description

Technical Field

[0001] This utility model belongs to the field of bucket wheel excavator technology, specifically referring to a hydraulic alignment device for a bucket wheel excavator. Background Technology

[0002] A bucket wheel stacker-reclaimer is a high-efficiency loading and unloading machine used in large dry bulk cargo yards, capable of both stacking and reclaiming materials. It consists of a belt conveyor arm that can tilt and swing horizontally, along with bucket wheels at its front end, a frame, and a running mechanism. The belt can run in both directions. During reclaiming, materials are picked up by the bucket wheels and conveyed out via the conveyor arm. During stacking, goods transported by the main conveyor are thrown into the yard via the conveyor arm. During operation, the driver's cab tilts along with the conveyor wall, resulting in a poor driving experience and potentially affecting the driver's work.

[0003] The hydraulic alignment device of the existing bucket wheel excavator adjusts the deviation of the driver's cab by raising and lowering the hydraulic rod and adds a shock-absorbing structure to reduce the vibration during the leveling. However, the above-mentioned alignment structure cannot be adjusted to a suitable size according to the size of the bucket wheel stacker-reclaimer, and cannot be used for driver's cabs of different sizes. In addition, the working environment of the bucket wheel stacker-reclaimer is poor, and the shock-absorbing structure is exposed to the outside and is easily blocked by dust, resulting in poor shock absorption effect. Utility Model Content

[0004] The problem this utility model aims to solve is that traditional hydraulic alignment devices are not suitable for bucket wheel excavators of different sizes, and the shock absorption structure is easily blocked by dust when exposed, resulting in poor shock absorption.

[0005] To solve the above-mentioned technical problems, this utility model proposes a hydraulic alignment device for a bucket wheel excavator, including a base, a hydraulic telescopic rod one fixed in the middle of the base, an installation ring fixed on the outer side of the hydraulic telescopic rod one, an adjustment structure on the installation ring, a limiting structure on the base, the adjustment structure being limited by the limiting structure, a hydraulic telescopic rod two hinged to the adjustment structure, and a shock-absorbing structure on the top of the hydraulic telescopic rod two.

[0006] Furthermore, the adjustable structure includes a horizontally arranged hydraulic telescopic rod three, the non-telescopic ends of the hydraulic telescopic rod three are circumferentially fixed on the mounting ring, and the telescopic ends of the hydraulic telescopic rod three are fixed with mounting plates.

[0007] Furthermore, the limiting structure includes a first slot, which is formed on the base. A vertical plate is fixed on the base, and the vertical plate is located on both sides of the first slot. A second slot is formed on the opposite side of the vertical plate. The bottom and side of the mounting plate are engaged in the first and second slots.

[0008] Furthermore, the bottom of the second hydraulic telescopic rod is hinged to one side of the mounting plate.

[0009] Furthermore, the shock-absorbing structure includes a support plate, the lower end of which is hinged to the upper end of the hydraulic telescopic rod. A circular plate is fixed on the upper side of the support plate, and a top plate is provided above the circular plate. The circular plate and the top plate are connected and fixed by a shock-absorbing spring. A sliding rod is fixed on the lower side of the top plate, and the lower end of the sliding rod is slidably disposed on the circular plate. The sliding rod is disposed inside the shock-absorbing spring, and the sliding rod and the shock-absorbing spring are provided with an array.

[0010] Furthermore, an annular baffle is fixed at the lower end of the top plate, and the lower end of the annular baffle is sleeved on the outside of the circular plate.

[0011] The beneficial effects of this utility model by adopting the above structure are as follows:

[0012] 1. By adjusting the length of the second hydraulic telescopic rod, the mounting plate slides within slots one and two to adjust the distance between the third hydraulic telescopic rod and the first hydraulic telescopic rod, thereby adjusting the distance between the top plate and the first hydraulic telescopic rod. This makes it suitable for bucket wheel excavators of different sizes, solving the problem that traditional hydraulic adjustment devices cannot be used for bucket wheel excavators of different sizes.

[0013] 2. An annular baffle is fixed to the lower end of the top plate. The lower end of the annular baffle is sleeved on the outside of the circular plate to prevent external debris from entering the damping spring and slide rod, which would affect the damping. This solves the problem that the damping structure is easily blocked by dust when exposed to the outside, resulting in poor damping effect. Attached Figure Description

[0023] As per the instruction manual Figure 3 As shown, the limiting structure 5 includes a slot 10, which is opened on the base 1. A vertical plate 11 is fixed on the base 1. The vertical plate 11 is located on both sides of the slot 10. A slot 2 12 is opened on the opposite side of the vertical plate 11. The bottom and side of the mounting plate 9 are engaged in the slot 10 and the slot 2 12.

[0024] As per the instruction manual Figure 4 As shown, the shock-absorbing structure 7 includes a support plate 13, the lower end of which is hinged to the upper end of the hydraulic telescopic rod 6. A circular plate 14 is fixed on the upper side of the support plate 13, and a top plate 15 is provided above the circular plate 14.
