Description

Technical Field

[0001] This utility model relates to the field of loader lifting technology, specifically to a loader lifting platform for silos. Background Technology

[0002] A silo is a warehouse used for storing bulk materials, and it is divided into two main categories: agricultural silos and industrial silos. Agricultural silos are used to store granular and powdery materials such as grains and feed; industrial silos are used to store bulk materials such as coke, cement, salt, and sugar. Existing silos have various plan shapes, including square, rectangular, polygonal, and circular. Cylindrical silos are the most widely used due to their reasonable wall stress distribution and economical material usage.

[0003] Silos are typically constructed using brick, wood, reinforced concrete, or steel. Small silos can also be made of plastic. Brick and stone are widely used due to their availability, low cost, and ease of construction. Larger brick and stone silos are reinforced with circumferential steel bars or reinforced concrete ring beams at regular intervals to withstand circumferential tensile forces. The silo opening is usually located 4 to 6 meters above the ground. During loading and unloading, due to the height of the opening, a loader is usually required. However, the limited boom length of the loader prevents it from moving to the opening, making loading and unloading extremely inconvenient. Therefore, a loader lifting platform for silos is designed to raise the loader to a certain height before loading and unloading, greatly improving operational efficiency. Utility Model Content

It achieves forward and backward movement via drive wheels and left and right steering via steering wheels. A lifting mechanism can raise the loader to a certain height and perform loading and unloading operations at the silo opening. An inclined block facilitates the loader's entry onto the lifting platform; after the loader reaches its designated position, the inclined block is removed. The lifting component in the lifting mechanism provides jacking force and drives the lifting platform up and down. During the lifting process, the guide bracket assembly rotates along with the lifting platform. When the lifting platform reaches a certain height under the action of the lifting component, a limiting mechanism limits the rotation of the guide bracket assembly, thereby providing auxiliary support to the lifting platform and improving stability after lifting. A guardrail assembly limits the loader's movement and provides protection. Attached Figure Description

The drive wheels 2 and steering wheels 3 adopt the existing wheel structure of a mobile trolley and realize functions such as forward, backward and steering, which will not be described in detail here.

[0018] A lifting mechanism 4 is provided on the base 1. The lifting mechanism 4 includes a fixed plate 41 disposed on the top of the base 1, which is arranged along the length of the base 1; a lifting plate 42 located above and parallel to the fixed plate 41; several lifting components 43 disposed between the fixed plate 41 and the lifting plate 42. The lifting components 43 adopt existing lifting structures such as jacks, which can bear a certain weight and lift the loader on the lifting plate 42. In this embodiment, the lifting components 43 are set in four groups and located at the four corners of the fixed plate 41. Six groups can also be set, with four distributed at the top four corners of the fixed plate 41 and the other two distributed at the top two ends of the fixed plate 41; and components disposed between the fixed plate 41 and the lifting plate 42. The guide bracket assembly 44 is provided in at least two sets, which are respectively located on both sides of the fixed plate 41 and the lifting plate 42. The two sets of guide bracket assemblies 44 are distributed along the width direction of the fixed plate 41 and the lifting plate 42, and the guide bracket assemblies 44 are arranged along the length direction of the fixed plate 41 and the lifting plate 42. One end of the lifting plate 42 is detachably connected to an inclined block 5. The high end of the inclined block 5 is flush with the top surface of the lifting plate 42 when it is not raised. The inclined block 5 is located at one end of the base 1 and its bottom is in contact with the ground. Specifically, one end of the lifting plate 42 is hinged to a tongue plate 45. The inclined surface of the inclined block 5 is provided with an installation groove 51 that matches the tongue plate 45. The bottom wall of the installation groove 51 is embedded with a magnetic block 52. The bottom surface of the tongue plate 45 is provided with an iron sheet that attracts the magnetic block 52. Align the edge of the inclined block 5 with the edge of the lifting plate 42, then rotate the tongue plate 45 and rotate it into the mounting groove 51 on the inclined block 5. The tongue plate 45 is limited by the attraction between the magnetic block 52 and the iron plate. At the same time, in this embodiment, the upper surface of the tongue plate 45 is flush with the inclined surface of the inclined block 5. Furthermore, the guide bracket assembly 44 is provided with a limiting mechanism 6 for limiting its rotation. When the lifting plate 42 is raised to a certain height, the rotation of the guide bracket assembly 44 is limited by the limiting mechanism 6, which can further improve the stability after the lifting. The top of the lifting plate 42 is surrounded by a guardrail assembly 7, which can limit the loader and also provide protection.

[0019] Specifically, the guide bracket assembly 44 includes a first hinge seat 441 disposed on the outer middle of the fixed plate 41, a second hinge seat 442 disposed on the outer middle of the lifting plate 42 and corresponding to the first hinge seat 441, two first sliders 443 respectively slidably disposed on the outer side of the fixed plate 41 and located on both sides of the first hinge seat 441, and two second sliders 444 respectively slidably disposed on the outer side of the lifting plate 42 and located on both sides of the second hinge seat 442. In this embodiment, both the fixed plate 41 and the lifting plate 42 have T-shaped grooves (not shown in the figure) on their outer sides. The first sliders 443 and the second sliders 444 are T-shaped structures and respectively match the corresponding T-shaped grooves; and are respectively arranged in a cross pattern. The first connecting rod 445 and the second connecting rod 446 are rotatably connected by a pin 449. The first connecting rod 445 and the second connecting rod 446 are respectively hinged to the first hinge seat 441 through the first guide rod 447, and the first connecting rod 445 and the second connecting rod 446 are respectively hinged to the second hinge seat 442 through the second guide rod 448. The two ends of the first connecting rod 445 are respectively hinged to a first slider 443 and a second slider 444, and the two ends of the second connecting rod 446 are respectively hinged to another first slider 443 and another second slider 444. The limiting mechanism 6 is provided at the end of the pin 449 outside the first connecting rod 445 and is used to limit the rotation between the first connecting rod 445 and the second connecting rod 446.

[0020] Specifically, the limiting mechanism 6 includes a circular plate 61 located outside the first connecting rod 445, a drive disk 62 rotatably disposed outside the circular plate 61, a shaft hole on the circular plate 61 matching the rotating shaft of the drive disk 62, a rotating cylinder 63 located inside the circular plate 61 and connected to the rotating shaft of the drive disk 62, the rotating shaft of the drive disk 62 passing through the shaft hole on the circular plate 61 and connected to the rotating cylinder 63; and two insert rods 64 symmetrically disposed on the outer edge of the circular plate 61 and slidably passing through the first connecting rod 445, the ends of the two insert rods 64 near the second connecting rod 46 having a circular structure, the rotating cylinder 63 being threadedly engaged with the end of the pin 449, the first connecting rod 445 having an insertion hole matching the insert rod 64, and the second connecting rod 446 having a positioning hole corresponding to the insert rod 64. Here, when the lifting plate 42 has not been fully raised, the positioning hole and the position of the insert rod 64 are offset, and when raised to the specified height, the positioning hole and the insert rod 64 are aligned. When the lifting plate 42 is raised to a certain height, the rotating drive disc 62 drives the rotating cylinder 63 to rotate. The rotating cylinder 63 moves in the direction close to the first connecting rod 445, and drives the two insert rods 64 to pass through the first connecting rod 445 and extend into the positioning holes on the second connecting rod 446, thereby limiting the rotation of the first connecting rod 445 and the second connecting rod 446. In this embodiment, when the insert rod 64 is not inserted into the second connecting rod 446, its end away from the circular plate 61 is flush with the end face of the first connecting rod 445 near the second connecting rod 446, which is the initial position of the insert rod 64.

[0021] The guardrail assembly 7 includes two fixed guardrails 71 respectively disposed on the top two sides of the lifting plate 42 and arranged along its length, and movable guardrails 72 respectively hinged to both ends of the fixed guardrails 71. The movable guardrail 72 on one fixed guardrail 71 is detachably connected to the movable guardrail 72 on the other corresponding fixed guardrail 71 by a latch. The latch can be an existing padlock, hook and latch, etc., and no specific limitation is made here.

[0022] In order to achieve intelligent control, in this embodiment, the bottom of the base 1 is provided with a controller 8 that is communicatively connected to the drive wheel 2, the steering wheel 3 and the lifting component 43 respectively; at the same time, a remote controller that matches the controller can also be provided, and the lifting platform can be driven to move forward, backward, turn and lift by operating the remote controller.

[0023] In use, open the two movable guardrails 72 on the same side, rotate the tongue plate 45 upward, and align the high end of the inclined block 5 with the top surface of the lifting plate 42 when it is not raised. After alignment, drive the tongue plate 45 to rotate and extend it into the mounting groove 51 on the inclined block 5. The position of the tongue plate 45 can be restricted by the action of the magnetic block 52 and the iron plate. Drive the loader onto the lifting plate 42. After driving, remove the inclined block 5 and lock the movable guardrail 72 on the same side with the latch. At this time, move the lifting platform to the designated position by driving the drive wheel 2 and steering wheel 3 (the loader can also be raised first and then moved to the designated position). Further activate the lifting component 43. The lifting component 43 gradually drives the lifting plate 42 to rise. At this time, the first junction seat 441, the second hinge seat 442, the first slider 443, the second slider 444, the first connecting rod 445, and the second connecting rod 446 are connected. 46. ​​With the cooperation of the first guide rod 447, the second guide rod 448, and the pin 449, the first connecting rod 445 and the second connecting rod 446 rotate. When the lifting plate 42 is raised to the specified height, the drive disc 62 drives the rotating cylinder 63 to rotate. The rotating cylinder 63 rotates along the pin 449 and moves in the direction close to the first connecting rod 445, thereby driving the two insert rods 64 to insert into the positioning holes on the second connecting rod 446, thereby limiting the rotation of the first connecting rod 445 and the second connecting rod 446. At this time, the guide bracket assembly 44 can provide auxiliary support for the lifting plate 42, improving the stability after lifting. After loading and unloading are completed, the drive disc 62 is driven to rotate in the opposite direction and the insert rods 64 are moved to the initial position. At this time, the lifting plate 42 can be reset by the lifting component 43, and then the inclined block 5 can be installed. Then the loader can be driven out.

[0024] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
