Description

Technical Field

[0001] The invention relates to the technical field of mechanical processing, and in particular to a hydraulic support structural part turnover auxiliary device. Background Art

[0002] The hydraulic support structure is one of the main components of the hydraulic support. The hydraulic support is a structure used to control the mine pressure of the coal mining face. At present, the hydraulic support structure is mainly manufactured by robot workstation welding, which mainly includes steel plate cutting, groove processing, assembly, welding, post-weld inspection and weld repair processes. Due to the limitation of the robotic arm of the welding robot, there are blind spots in the welding angle, and some positions cannot be welded. Therefore, after the welding robot completes the welding, the hydraulic support structure needs to be transferred to the manual workbench for the repair welding process. When the manual welders are working upright, the overhead crane will lift the structure and flip it over to perform padding operations.

[0003] Since the center of gravity of the hydraulic support structure is forward when it is standing, it is not easy to flip it only by the overhead crane when the employees finish the work and turn it over. At present, the structural parts are turned over by the driving torque of the trolley or the car. In a limited space, this operation is easy to slip during the belt removal, resulting in an increase in the range of movement of the structural parts, and the risk factor of the workers next door is also increasing. At the same time, it also increases the failure rate of the overhead crane. The maintenance of the overhead crane will also lead to a decrease in work efficiency. For this reason, a hydraulic support structure flipping auxiliary device is proposed. This auxiliary device can perfectly solve the above problems, reduce the range of movement of the structural parts when flipping, increase the safety factor of the workers next door, reduce the use cost of the overhead crane, and extend the service life of the overhead crane. Summary of the invention

[0004] The purpose of the present invention is to provide a hydraulic support structure flip auxiliary device to solve the problems raised in the background technology. The specific technical solution is as follows:

[0005] To achieve the above-mentioned purpose and other related purposes, the present invention provides a hydraulic support structural member flipping auxiliary device, including a base, a side top structure is arranged on one side of the base, and the side top structure is used to support one side of the structural member. The base is also provided with a bracket, and a support plate is rotatably mounted on the bracket. The support plate and the bracket form a lever structure, and a section of the support plate from the end point of the side top structure close to the rotation point is a short side, and a section of the support plate from the end point of the side top structure away from the rotation point is a long side.

[0006] Preferably, the distance H between the side top structure and the support plate in the vertical state satisfies the following formula:

[0007]

[0008] Where: h is the height of the structural component patch.

[0009] Preferably, reinforcing ribs are provided on the lower side of the support plate.

[0010] Preferably, an auxiliary supporting structure is provided in the middle of the long side, one end of the auxiliary supporting structure is connected to the long side, and the other end is connected to the base.

[0011] Preferably, a limiting rod is provided on the lower side of the support plate, and a limiting groove corresponding to the limiting rod is provided on the base.

[0012] Preferably, the side top structure includes a vertical plate, a slide plate, and a driving structure. The vertical plate is fixedly connected to the base. A sliding groove is provided on the vertical plate. The slide plate slides through the sliding groove. The slide plate slides horizontally in the sliding groove. A driving structure is provided on the slide plate, and the driving structure is used to control the sliding of the slide plate.

[0013] Preferably, the driving structure comprises a lead screw and a rotating member, the lead screw is mounted on the vertical plate, a nut on the lead screw is connected to the slide plate, and the rotating member is connected to the lead screw.

[0014] Preferably, the rotating member is a hand wheel or a motor for controlling the operation of the lead screw.

[0015] Preferably, the auxiliary support structure adopts a buffer hydraulic cylinder, and two ends of the buffer hydraulic cylinder are rotatably mounted on the support plate and the base respectively.

[0016] The hydraulic support structure flip auxiliary device provided by the present invention has the following beneficial effects:

[0017] 1. By setting up the side top structure and forming a lever structure with the support plate and the bracket, under normal conditions, the structural parts can be placed on the long side for padding operations. During the operation, the side top structure will force the structural parts to tilt to the right, and finally the right side of the structural parts will fit with the upper surface of the support plate. As the overhead crane continues to lower the structural parts, the structural parts will be laid down, and then the left side of the structural parts will be lifted by the hook and placed on the workbench. After the flipping is completed, the structural parts will stand on the workbench, and the processed surface will face the welding workers, which is convenient for manual repair welding. During the entire flipping process, the side top structure and the support plate provide stable support for the structural parts, and there is no need for a large or small car to provide torque output, which reduces the range of activities of the structural parts during flipping, increases the safety factor of the workers next door, reduces the use cost of the overhead crane, and extends the service life of the overhead crane.

[0018] 2. By adding reinforcing ribs, auxiliary support structures, limit rods and other structures, the strength of the support plate is improved, avoiding the problem of deformation of the support plate due to the heavy pressure of the structural parts.

[0019] 3. By adding vertical plates, skateboards and driving structures, the horizontal movement of the skateboard can be controlled by the driving structure, so as to adjust the distance H between the side top structure and the support plate in the vertical state, that is, the distance between the rightmost side of the skateboard and the support plate in the vertical state, so as to adjust the distance H according to the height h of the structural component patch, so as to be suitable for the flipping work of structural components with different patch heights.

The advantages and features of the present invention will become clearer according to the following description. It should be noted that the accompanying drawings are all in a very simplified form and are not in precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0029] It should be noted that the illustrations provided in the following embodiments are only used to illustrate the basic concept of the present invention in a schematic manner, and thus the illustrations only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the form, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0030] Embodiment 1:

[0031] A hydraulic support structure flip auxiliary device, such as Figure 1 As shown, it includes a base 1, one side of the base 1 is provided with a side top structure 2, the side top structure 2 is used to support one side of a structural member 3, the base 1 is also provided with a bracket 4, a support plate 5 is rotatably mounted on the bracket 4, the support plate 5 and the bracket 4 form a lever structure, a section of the support plate 5 close to the end point of the side top structure 2 to the rotation point is a short side 501, and a section of the support plate 5 away from the end point of the side top structure 2 to the rotation point is a long side 502.

[0032] Under normal conditions, the weight of the long side 502 of the support plate 5 is large and presses downward, so that the short side 501 of the support plate 5 is tilted to form an inclined surface. At this time, the structural member 3 can be placed on the long side 502 to perform padding operations, such as Figure 2As shown, the inclined surface is used to pad one side of the structural member 3 to facilitate manual repair welding by welding workers. During the operation, the structural member 3 is lifted by the overhead crane and moved above the support plate 5. One side of the structural member 3 should be located above the side top structure 2. Then the structural member 3 is moved down by the overhead crane. The structural member 3 is first pressed on the short side 501. The weight of the structural member 3 will press down the short side 501, causing the support plate 5 to rotate counterclockwise. In the process of the structural member 3 moving downward, the left side of the structural member 3 contacts the side top structure 2. The width of the left side of the structural member 3 contacting the side top structure 2 is smaller than half of the height h of the patch of the structural member 3. The side top structure 2 will force the structural member 3 to tilt to the right. In this process, the right side of the structural member 3 will continue to press down the short side 501, causing the support plate 5 to continue to rotate. Finally, the right side of the structural member 3 is aligned with the upper side of the support plate 5. The surface fits. As the overhead crane continues to lower the structural member 3, if the center of gravity of the structural member 3 is on the long side 502, the structural member 3 is completely overturned, and then the left side of the structural member is lifted by the hook and placed on the workbench. After the overturning is completed, the structural member is in a posture of standing on the workbench. If the center of gravity of the structural member 3 is on the short side 502, the overhead crane drags the structural member 3 to the right until the center of gravity of the structural member 3 moves to the long side, and the structural member 3 is completely overturned. Then the left side of the structural member is lifted by the hook and placed on the workbench to complete the overturning. During the entire overturning process, the side top structure 2 and the support plate 5 provide stable support for the structural member 3, and there is no need for a large or small car to provide torque output, which reduces the range of activity of the structural member 3 during overturning, increases the safety factor of the adjacent workers, reduces the use cost of the overhead crane, and extends the service life of the overhead crane.

[0033] See also Figure 6 In order to prevent the structural member 3 from slipping off the side roof structure 2 and falling between the side roof structure 2 and the support plate 5, the distance H between the side roof structure 2 and the support plate 5 in the vertical state must satisfy the following formula:

[0034]

[0035] Where: h is the patch height of structural component 3.

[0036] Embodiment 2:

[0037] See also Figure 3On the basis of Example 1, in order to prevent the support plate 5 from bending, a reinforcing rib 503 is provided on the lower side of the support plate 5; further, an auxiliary support structure 504 is provided in the middle of the long side 502, one end of the auxiliary support structure 504 is connected to the long side 502, and the other end is connected to the base 1; further, a limiting rod 505 is provided on the lower side of the support plate 5, and a limiting groove 101 corresponding to the limiting rod 505 is provided on the base 1. In a normal state, the limiting rod 505 is located in the limiting groove 101. When the pad is activated, the structural member 3 is supported on the long side 502. Due to the limiting effect of the limiting rod 505 and the limiting groove 101, the support plate 5 is prevented from receiving the heavy pressure of the structural member 3 and causing ductile deformation of the metal.

[0038] See also Figure 4 In order to adapt to the flipping work of the structural member 3 with different patch heights, the side top structure 2 includes a vertical plate 201, a slide plate 202, and a driving structure 203. The vertical plate 201 is fixedly connected to the base 1. A slide groove is opened on the vertical plate 201. The slide plate 202 slides through the slide groove. The slide plate 202 slides horizontally in the slide groove. A driving structure 203 is provided on the slide plate 202. The driving structure 203 is used to control the sliding of the slide plate 202. The driving structure 203 includes a lead screw and a rotating member. The lead screw is installed on the vertical plate 201. The nut on the lead screw is connected to the slide plate 202. The rotating member is connected to the lead screw. The rotating member is a hand wheel or a motor, which is used to control the work of the lead screw and realize the translation of the slide plate 202.

[0039] See also Figure 5 By controlling the horizontal movement of the slide plate 202, the distance H between the side top structure 2 and the support plate 5 in the vertical state, that is, the distance between the rightmost side of the slide plate 202 and the support plate 5 in the vertical state, is adjusted, so that the distance H can be adjusted according to the patch height h of the structural member 3, thereby being suitable for the flipping work of the structural members 3 with different patch heights.

[0040] See also Figure 3 In order to avoid accelerated collision when the structural member 3 contacts the support plate 5 during flipping, the auxiliary support structure 504 adopts a buffer hydraulic cylinder, and the two ends of the buffer hydraulic cylinder are rotatably installed on the support plate 5 and the base 1 respectively. When the buffer hydraulic cylinder is fully retracted, the limit rod 505 is located in the limit groove 101, and the buffer hydraulic cylinder plays a supporting role. During the flipping operation, the support plate 5 rotates counterclockwise, and when the buffer hydraulic cylinder is stretched, it plays a role in slowing down the rotation of the support plate 5.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present invention.
