Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hydraulic car unloading machines, in particular to a bidirectional hydraulic car unloading machine. Background Art
[0002] Hydraulic platform unloaders are primarily used for the rapid unloading of bulk materials, improving their transport efficiency. They primarily include side-tip and rear-tip hydraulic platform unloaders. The rear-tip hydraulic platform unloader is used for rear-tip unloading. The truck, loaded with bulk materials, is driven onto the rear platform, with the rear of the vehicle positioned at the unloading port. A hydraulic transmission drives the rear platform backward, causing the truck to flip backward, completing the unloading process. Side-tip unloaders are used for side-tip unloading. The truck, loaded with bulk materials, is driven onto the side platform, with the side of the vehicle positioned at the unloading port. A hydraulic transmission drives the side platform sideways, causing the truck to flip, completing the unloading process.
[0003] In the prior art, a side-tilt hydraulic unloader can usually only flip to one side to unload the vehicle. Therefore, a hydraulic unloader can only unload the vehicle in a fixed area. This means that a hydraulic unloader is required for each unloading area, resulting in a large number of hydraulic unloaders being required, which increases the unloading cost. Utility Model Content
[0004] The purpose of this utility model is to provide a two-way hydraulic unloading machine, which can unload goods on the left and right sides of the flap. One hydraulic unloading machine can unload goods in two unloading areas on both sides, thereby increasing the unloading area of the unloading machine, reducing the number of unloading machines used in the unloading area, and reducing unloading costs.

[0006] Preferably, the angle between the outer side surface of the support arm and the flap is an obtuse angle.
[0007] Preferably, the driving seat is configured as an arc-shaped structure.
[0008] Preferably, the bottom of the hydraulic rod is fixed below the flap via an axle seat.
[0009] Preferably, the elastic member is a spring or a tension spring.
[0010] Preferably, multiple hydraulic rods located on the left and right sides are provided along the extension direction of the force-bearing rod.
[0011] Compared with the prior art, the beneficial effects of the present invention are:
[0012] The utility model discloses that the unloader can unload goods on the left and right sides of the flap. A hydraulic unloader can unload goods in two unloading areas on both sides, thereby increasing the unloading area of the unloader, reducing the number of unloaders used in the unloading area, and reducing the unloading cost.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0019] For the convenience of description, the coordinate system is defined as follows Figure 1 As shown, the left-right direction is the horizontal direction, the front-back direction is the longitudinal direction, and the up-down direction is the vertical direction.
[0020] like Figures 1 to 3As shown, a bidirectional hydraulic unloading machine includes a flap 1, and two support arms 2 extending forward and backward are symmetrically arranged at the bottom of the flap 1, and a support rod 3 extending forward and backward is arranged below the flap 1 and on the outside of the two support arms 2 (with the opposite side of the two support arms 2 as the outside), and a force-bearing rod 4 extending forward and backward is fixedly arranged at the bottom of the flap 1 and on the outside of the two support rods 3, and a hydraulic rod 5 is arranged below the force-bearing rod 4, and a driving seat 6 for driving the force-bearing rod 5 to be lifted is provided on the driving arm of the hydraulic rod 5, and an elastic member for adjusting the hydraulic rod 5 to be in a vertical state is provided on one side of the hydraulic rod 5.
[0021] Specifically, the flap 1 is arranged above the ground of the unloading site and close to the ground according to the actual scene of the unloading site. The bottom of the flap 1 is a pit for installation. The two support rods 3 are fixed in the pit. The foundation is pre-laid in the pit, and concrete is poured as the installation base. The support rods 3 are fixed to the installation base through connecting rods.
[0022] Specifically, the support arm 2 is welded to the bottom of the flap 1 , and the force-bearing rod 4 is welded to the bottom of the flap 1 through a connecting rod.
[0023] Working Principle: A loaded vehicle to be unloaded is driven onto flap 1 from the front or rear side. The unloading direction is selected based on the actual unloading needs. For example, unloading to the left is controlled by extending the drive arm of the right-hand hydraulic rod 5. The drive arm moves the drive seat 6 upward and contacts the corresponding force-bearing rod 4. After contacting the force-bearing rod 3, the drive seat 6 continues to move upward, driven by the corresponding hydraulic rod 5. The flap 1 flips to the left, and the loaded vehicle on the flap 1 tilts to the left and unloads. After unloading is completed, the corresponding hydraulic rod 5 is controlled to retract until the flap 1 is horizontal again.
[0024] It should be noted that if Figure 2 As shown, the angle between the outer side surface of the support arm 2 and the flap 1 is an obtuse angle, preferably between 95°-110°. In this way, the angle formed between the outer side surface of the support arm 2 and the bottom surface of the flap 1 has enough space for the flap 1 to rotate around one support rod 3, while the support rod 3 on the other side does not interfere with its corresponding support arm 2, ensuring that the flap 1 can flip left and right normally.
[0025] Preferably, in this embodiment, the driving seat 6 is configured as an arc structure with an arc angle of 180°. The diameter of the arc structure is larger than the diameter of the force-bearing rod 4. While ensuring smooth driving of the force-bearing rod 3 to rotate upward, it ensures that the driving seat 6 has enough space to accommodate the force-bearing rod 4 to prevent the force-bearing rod 4 from falling off the driving seat 6.
[0026] Specifically in this embodiment, the bottom of the hydraulic rod 5 is fixed in the groove below the flap 1 through the axle seat 7. When the flap 1 rotates upward, the force rod 4 will produce a horizontal displacement difference. The bottom of the hydraulic rod 5 is hinged in the groove and can rotate in the horizontal plane to adapt to the horizontal displacement difference of the force rod 4 and ensure smooth flipping of the flap 1.
[0027] As a specific embodiment, the elastic member adopts a spring or a tension spring. Taking spring 8 as an example, one end of the spring 8 is connected to the main body of the hydraulic rod 5, and the other end of the spring 8 is connected to the side wall in the groove. When the spring 8 and the hydraulic rod 5 are not subjected to external force, the hydraulic rod 5 is in a vertical state, ensuring that when the hydraulic rod 5 extends the driving arm upward, the driving seat 6 can stably and accurately engage with the force-bearing rod 4.
[0028] In this embodiment, multiple hydraulic rods 5 are provided on the left and right sides along the extension direction of the force-bearing rod 4. The hydraulic rods 5 on each side are evenly arranged and evenly contact the force-bearing rod 4 in order to increase the driving stability and driving force of the flap 1.
[0029] It should be noted that this embodiment also includes a hydraulic rod controller for controlling the operation of the two hydraulic rods 5, and a hydraulic station for providing hydraulic pressure to the hydraulic rods 5. The above-mentioned hydraulic rod controller, hydraulic station and hydraulic rods all belong to existing conventional technologies, and their specific connection methods will not be described in detail here.
[0030] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
