Description

Technical Field

[0001] This utility model relates to the field of hydraulic support maintenance technology, and in particular to a hydraulic support tilting device. Background Technology

[0002] The statements herein provide only background information related to this invention and do not necessarily constitute prior art.

[0003] To facilitate maintenance of the hydraulic support top beam and shield beam, they typically need to be rotated. Currently, the rotation of the hydraulic support top beam and shield beam mainly relies on cranes, which is very inefficient and poses a high safety risk.

[0004] Currently, to improve safety and turning efficiency, dedicated turning mechanisms are used. Utility model patent CN207294117 U discloses a hydraulic support beam turning machine. The beam to be inspected is placed on a left turning platform and clamped by a left clamping device. Under the action of a left lifting device, the left turning platform is turned. Subsequently, a pushing device pushes the left turning platform towards a right turning platform that has already turned 90°. Next, the right clamping device clamps the beam, and the left clamping device releases. Finally, the right lifting device slowly lowers the right turning platform. However, in practice, when the thickness of the beam being turned is small, there is a certain gap between the beam on the left turning platform and the right turning platform after the beam has turned 90°. This causes the beam to move towards the right turning platform due to gravity during the turning process, potentially colliding with it and easily damaging the right turning platform, posing a safety risk. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned shortcomings by providing a hydraulic support tilting device that improves tilting safety.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a hydraulic support flipping device, comprising a base, a first flipping platform and a second flipping platform rotatably mounted on the base, a first telescopic component between the base and the first flipping platform, the first telescopic component being used to push the first flipping platform to flip 90 degrees and place the items on it onto the second flipping platform, a second telescopic component between the base and the second flipping platform, the second telescopic component being used to push the second flipping platform to flip 90 degrees, and a fastening mechanism for pulling the items on the first flipping platform toward one side of the second flipping platform, the fastening mechanism comprising at least one multi-stage telescopic component mounted on the first flipping platform, a rotating seat being provided at the output end of the multi-stage telescopic component, a push-pull plate being rotatably mounted on the rotating seat via a torsion spring, a stop block located in the rotation area of ​​the push-pull plate being provided on the side of the rotating seat away from the multi-stage telescopic component, the push-pull plate being located in the rotation area of ​​the first flipping platform when the torsion spring is in its natural state, and a through hole for the push-pull plate to pass through being provided on the first flipping platform.

[0007] Furthermore, both the first and second flipping platforms are L-shaped plates, and the placement surfaces of both the first and second flipping platforms for placing items are equipped with multiple rollers.

[0008] Furthermore, the base includes a seat body, on which a slide plate that can move toward or away from the second flip platform is slidably disposed. The first flip platform is rotatably disposed on the slide plate. The seat body is also provided with a fixed seat located on the side of the slide plate away from the second flip platform. An adjusting screw is threaded through the fixed seat, and one end of the adjusting screw is rotatably connected to the slide plate.

[0009] Furthermore, both the first and second tilting platforms are provided with slots for inserting forklift forks.

[0010] Furthermore, the side of the push-pull plate that contacts the item is detachably provided with a flexible protective sleeve.

[0011] The beneficial effects of this utility model are reflected in: In this invention, when the first flipping platform rotates 90 degrees, the output end of the multi-stage telescopic component retracts, allowing the push-pull plate to pass through the perforation into the first flipping platform and abut against the object on it. Subsequently, the continued retraction of the output end of the multi-stage telescopic component will drive the push-pull plate to pull the object towards the second flipping platform until the object abuts against the second flipping platform and cannot move, thereby ensuring that the object can remain stable when the second flipping platform is flipped, thus improving the safety of the flipping.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0015] Please see Figure 1-3 This utility model discloses a hydraulic support flipping device, including a base 1, a first flipping platform 2 and a second flipping platform 3 rotatably mounted on the base 1, a first telescopic component between the base 1 and the first flipping platform 2, the first telescopic component being used to push the first flipping platform 2 to flip 90 degrees and place the items on it onto the second flipping platform 3, a second telescopic component between the base 1 and the second flipping platform 3, the second telescopic component being used to push the second flipping platform 3 to flip 90 degrees, and also includes a fastening mechanism 4 for pulling the items on the first flipping platform 2 toward one side of the second flipping platform 3, the fastening mechanism 4 including at least one multi-stage telescopic component 41 mounted on the first flipping platform 2, a rotating seat 42 mounted at the output end of the multi-stage telescopic component 41, a push-pull plate 43 rotatably mounted on the rotating seat 42 via a torsion spring, a stop block 44 located in the rotation area of ​​the push-pull plate 43 on the side of the rotating seat 42 away from the multi-stage telescopic component 41, when the torsion spring is in its natural state, the push-pull plate 43 is located in the rotation area of ​​the first flipping platform 2, and a through hole for the push-pull plate 43 to pass through is provided on the first flipping platform 2.

[0016] In this invention, the top beam and shield beam to be flipped are placed on the first flipping platform 2. The first flipping platform 2 is driven to rotate 90 degrees by the first telescopic component, causing the top beam and shield beam to change from a horizontal to a vertical position. During this flipping process, because the push-pull plate 43 is located within the rotation area of ​​the first flipping platform 2, when the push-pull plate 43 in its natural state comes into contact with an object on the first flipping platform 2, it will be pushed by the object and fold towards the side closer to the multi-stage telescopic component 41, without affecting the movement of the first flipping platform 2 and the object on it. Afterwards, the output end of the multi-stage telescopic component 41 extends, causing the push-pull plate 43 to move away from the first flipping platform 2. The second flipping platform 3 moves to one side until the push-pull plate 43 is no longer blocked by the first flipping platform 2 or the object on it, so that the push-pull plate 43 can rotate and reset under the action of the torsion spring. Then, the output end of the multi-stage telescopic component 41 retracts, so that the push-pull plate 43 passes through the perforation of the first flipping platform 2 and abuts against the object on it. Then, the continued retraction of the output end of the multi-stage telescopic component 41 will drive the push-pull plate 43 to pull the object to the side of the second flipping platform 3 until the object abuts against the second flipping platform 3 and cannot move, thereby ensuring that the object can remain stable when the second flipping platform 3 flips, thus achieving the purpose of improving the flipping safety.

[0017] It should be noted that both the first telescopic component and the second telescopic component are preferably hydraulic telescopic components (not shown in the figure), and the multi-stage telescopic component 41 is preferably a multi-stage electric cylinder. Hydraulic telescopic components and multi-stage electric cylinders are common knowledge in the field, so their specific structural composition and working principle will not be described in detail in this article.

[0018] In specific implementation, the second flipping platform 3 is equipped with a photoelectric sensor for monitoring the distance between the object and the second flipping platform 3. The photoelectric sensor and the multi-stage telescopic component 41 have closed-loop feedback to control the telescopic distance of the multi-stage telescopic component 41.

[0019] In one embodiment, both the first flipping platform 2 and the second flipping platform 3 are L-shaped plates, and both the first flipping platform 2 and the second flipping platform 3 are provided with multiple rollers on the placement surface for placing items.

[0020] This design reduces the resistance to movement of an object as it is pushed towards the second flipping platform 3 by the push-pull plate 43 and rests on the rollers.

[0021] In one embodiment, the base 1 includes a seat body 11, on which a slide plate 12 that can move toward or away from the second flip platform 3 is slidably disposed. The first flip platform 2 is rotatably disposed on the slide plate 12. The seat body 11 is also provided with a fixed seat 13 located on the side of the slide plate 12 away from the second flip platform 3. An adjusting screw 14 is threaded through the fixed seat 13, and one end of the adjusting screw 14 is rotatably connected to the slide plate 12.

[0022] With this design, when the thickness of the object being flipped changes, the sliding plate 12 can be pushed to slide by rotating the adjusting screw 14, adjusting the distance between the first flipping platform 2 and the second flipping platform 3, ensuring that objects of various thicknesses will not collide with the second flipping platform 3 during flipping, thus improving the compatibility of this device.

[0023] In one embodiment, both the first tilting platform 2 and the second tilting platform 3 are provided with slots for inserting forklift forks.

[0024] This design allows operators to place objects on the first tilting platform 2 using a forklift. After the object is tilted on the second tilting platform 3, the forklift is inserted under the object to control the extension of the multi-stage telescopic component 41, creating lifting space between the object and the push-pull plate 43. The forklift is then used to lift the object off the second tilting platform 3, and then the object is moved horizontally to be removed.

[0025] In one embodiment, the side of the push-pull plate 43 that contacts the item is detachably provided with a flexible sheath.

[0026] This design prevents the sliding panel 43 from coming into contact with the object and causing damage.

[0027] In practice, the flexible sheath is a rubber sleeve or a silicone sleeve.

[0028] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0029] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0030] Additionally, "multiple" refers to two or more.

[0031] 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.
