Description

Technical Field

[0001] The utility model relates to the technical field of welding accessory equipment, in particular to an edge welding slag receiving platform. Background Art

[0002] During the welding process, when the electrode or wire melts, in addition to forming the weld filler metal, welding slag will also be produced. Welding slag is mainly composed of metal oxides, non-metallic oxides and other mineral salts, and its density is usually lower than that of liquid iron during welding. When the welding arc is generated, the welding slag may become loose due to the high temperature. At the same time, due to its lower density, it may splash out from the weld area under the influence of welding airflow, gravity or other external forces. Therefore, when performing welding construction in high-altitude environments, relevant protective work needs to be done.

[0003] Taking bridge deck construction as an example, there may be structures such as steel bars on the edge of the bridge deck that require welding work, so bridge deck welding construction is considered high-altitude work. At the same time, bridge deck welding construction is usually carried out on high piers, across existing lines, and in densely populated areas. If there are no relevant protective measures during welding, it is easy for welding slag to fall, causing harm to pedestrians and vehicles passing by outside and below the edge of the bridge surface; at the same time, due to the high temperature of the welding slag, it is easy to cause fire hazards when the weather is dry.

[0004] Therefore, there is an urgent need for a welding slag receiving device suitable for use at construction sites, which can receive the splashed and fallen welding slag at the welding position at the edge while reducing interference with welding construction, so as to prevent safety accidents. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a platform for receiving welding slag at the edge. The structure of the platform is relatively simple, the maintenance and repair are convenient, the overall service life is relatively long, and it is suitable for use on construction sites. At the same time, while the platform can receive the welding slag splashed and dropped outward from the edge, it does not contact or interfere with the welding object, and does not interfere with the welding work of the construction personnel, so that the platform has good applicability.

[0006] The utility model is realized through the following technical solutions.

[0007] A welding slag receiving platform at an edge, used for receiving welding slag generated at a welding point at an edge on a construction platform, characterized in that it comprises:

[0008] The counterweight part is used to prevent the edge welding slag receiving platform from overturning; in particular, when the receiving platform receives a certain amount of welding slag, the counterweight part can prevent the overall center of gravity of the receiving platform from shifting and causing the receiving platform to overturn out of the construction platform.

[0009] The connecting part includes a supporting part, a hanging part and a hanging part. One end of the supporting part is connected to the counterweight part, and the other end is connected to the hanging part for supporting the hanging part. When the receiving platform is in working state, the hanging part is away from the table top of the construction platform to form a construction space for accommodating construction personnel to carry out welding work, and at the same time, the hanging part connected to the hanging part is suspended outside the construction platform. The structural setting of the hanging part not only achieves the effect of the external hanging part and the receiving part thereon to realize the receiving function, but also reduces the interference of the overall platform on the welding work.

[0010] The receiving part is fixedly connected to the hanging part. When the receiving platform is in working state, the receiving part is suspended outside the construction platform along with the hanging part to receive the welding slag.

[0011] Sometimes, there is a lack of structures for fixing construction auxiliary equipment near the welding slag construction points at the edge. Taking the bridge deck welding construction environment as an example, the bridge deck is relatively flat as a whole, and only the protruding and exposed steel bars at the edge can be used as fixing points for construction auxiliary equipment. However, in welding work, the exposed steel bars are usually the construction objects of welding, and it is inconvenient to use them as fixing points for the welding slag receiving platform; and if the steel bars are used as fixing points, then in the long-term welding slag receiving work process, with the increase of welding slag amount and the weight of the welding slag receiving platform itself, the steel bars may be deformed, thereby affecting subsequent welding and other work.

[0012] The receiving platform described in the utility model can receive the welding slag and place it without contacting or interfering with the welding object, thereby reducing the impact on the welding work.

[0013] As a further improvement of the present invention, the suspension includes a first suspension and a second suspension, wherein the first suspension is connected to the support member, the second suspension is connected to the hanging member, and the first suspension and the second suspension are connected via an adjusting component.

[0014] The positional relationship between the first suspension and the second suspension can be changed by the adjusting member, thereby changing the overall structure and / or size of the suspension, and further adjusting the positional relationship between the receiving portion and the counterweight portion. The adjusting member can be a slide rail and matching rollers, a telescopic arm structure, etc.

[0015] When the receiving platform is in a non-working state, the adjusting member can make the receiving part and the counterweight part close to each other, and the center of gravity of the receiving platform will be placed near the counterweight part, so that the receiving platform is not easy to overturn. At the same time, in this case, the overall space occupied by the receiving platform is reduced, and it is easier to store.

[0016] When the receiving platform needs to be switched to a working state, the receiving part can be moved away from the counterweight part until it returns to the original state through the adjusting member.

[0017] As a further improvement of the present invention, the adjusting member is a foldable hinge structure, and the opening of the foldable hinge structure faces downward, so that the receiving part always passes through the top space of the suspension when it is retracted. When the suspension is folded, the receiving part is retracted; when the suspension is extended, the receiving part is suspended outside, so that the receiving platform is in a working state.

[0018] The composition of the adjustment component is simple, which is convenient for subsequent repair and maintenance work and is suitable for complex construction site environments. At the same time, under this structure, in the process of unfolding the suspension to release the receiving part, the second suspension is centered on the foldable hinge structure and away from the first suspension. In the process of releasing the receiving part, it is first lifted and then lowered until it is in a working state. The receiving part is away from the welding object during the lifting process, so it does not touch the welding object, and when it is lowered to the lowest point, it is placed at the edge of the construction platform and does not contact the welding object. Therefore, under this adjustment component, during the state conversion process of the receiving platform, the receiving part will not interfere with the welding object, preventing the receiving part from affecting the welding object.

[0019] As a further improvement of the utility model, the receiving part includes a receiving chassis and a receiving fence, and the receiving fence is arranged around the receiving chassis to form a accommodating space to prevent welding slag placed in the accommodating space from falling out of the receiving part when the receiving part moves.

[0020] In particular, when the receiving part is retracted, the receiving part can be lifted up by the folding hinge structure so that it does not interfere with the welding object, and then the receiving platform can be moved as a whole so that the receiving part can be horizontally retracted onto the construction platform. After the welding slag in the receiving part is recovered, the receiving platform can be folded and stored.

[0021] With this structure, when welding slag is received, there is no need to push the receiving platform as a whole to a place where no welding object is provided and then retract the receiving part, so that the overall use process of the receiving platform is more convenient.

[0022] As a further improvement of the present invention, the counterweight part includes a load-bearing plate and a movable counterweight block, and the load-bearing plate is used for supporting the movable counterweight block.

[0023] After the adjusting member is included to fold and store the receiving platform, it can be ensured that the center of gravity of the receiving platform is always placed near the counterweight part in the non-working state. Therefore, the counterweight part can be a structure in which a movable counterweight block is separated from the bearing plate.

[0024] When the receiving platform is finely adjusted before switching to the working state, the movable counterweight block can be removed; after the position adjustment of the receiving platform is completed, the movable counterweight block is added to stabilize the center of gravity.

[0025] As a further improvement of the utility model, anti-slip patterns are arranged on the bearing surface of the load-bearing plate.

[0026] As a further improvement of the utility model, the receiving part includes a receiving protection plate. When the receiving platform is in working state, the receiving protection plate is placed on the side of the receiving part away from the construction platform to block the splashing welding slag.

[0027] During welding, the welding slag generated includes splashing welding slag and falling welding slag. The moving trajectory of falling welding slag is easy to predict. However, the splashing height and horizontal splashing distance of splashing welding slag are difficult to predict. Generally, a larger receiving part is provided to receive all the falling and splashing welding slag.

[0028] However, after the receiving and protecting plate is provided, the receiving and protecting plate can effectively block and guide the splashing welding slag. Under this structure, only a smaller receiving part is required to receive the falling welding slag and at the same time, the splashing welding slag can be received through the guidance of the receiving and protecting plate to protect the personnel and equipment below.

[0029] As a further improvement of the present invention, reinforcing ribs are provided between the support member and the suspension member, thereby strengthening the load-bearing capacity of the suspension member and increasing the amount of welding slag that can be received by the receiving portion.

[0030] As a further improvement of the utility model, a plurality of universal wheels are arranged at the bottom of the counterweight part, which are used to move and transport the receiving platform when it is not in working state; a corresponding locking device is arranged on the universal wheel, which can lock the universal wheel to prevent the receiving platform from offset and sliding when it is in working state.

[0031] As a further improvement of the present invention, the counterweight part further includes a warning plate, and the warning plate is provided with a warning pattern and / or a warning slogan.

[0032] The beneficial effects of the utility model include:

[0033] (1) While playing the role of receiving the welding slag dropped and splashed at the edge, it does not contact or interfere with the welding object and does not affect the welding work;

[0034] (2) It has a simple structure, low manufacturing cost, is easy to repair and maintain, and is suitable for use in construction sites;

[0035] (3) Through structural improvements, it is convenient for construction workers to adjust the position of the receiving platform so as to move it to different construction sites; it is also convenient for construction workers to fold and store the receiving platform as a whole without taking up too much storage space.

[0039] Figure 3 This is a structural schematic diagram of the edge welding slag receiving platform in working condition. DETAILED DESCRIPTION

[0040] The utility model is further described in detail below based on the accompanying drawings and implementation cases.

[0041] The directional terms such as up, down, left, right, front, back, front, back, top, bottom, etc. mentioned or may be mentioned in this specification are defined relative to the structures shown in the drawings. The words "inside" and "outside" refer to the direction toward or away from the geometric center of a specific component, respectively. They are relative concepts, and therefore may change accordingly according to different locations and different usage conditions. Therefore, these or other directional terms should not be interpreted as restrictive terms.

[0042] In the embodiment, bridge deck construction is taken as an example. During the bridge deck construction process, it is necessary to weld the exposed steel bars at the edge. During the welding process, welding slag will be generated, some of which will fall directly, and some will fall after splashing. Due to the edge of the welding position, some of the welding slag will fly out of the construction platform directly and fall downwards.

[0043] Embodiment 1:

[0044] A welding slag receiving platform is used to receive welding slag generated at the welding point on the edge of the construction platform. Figure 1 As shown, it includes a counterweight part 1, a connecting part 2 and a receiving part 3. In order to receive the welding slag generated at the welding position at the edge, when in working state, Figure 3 As shown, the receiving part 3 needs to be suspended outside the construction platform, and the suspension is mainly achieved through the connecting part 2. At the same time, in order to prevent the receiving platform as a whole from tipping over toward the position of the receiving part 3, the connecting part 2 is connected to the counterweight part 1, and the counterweight part 1 relies on its own large weight to always stabilize the center of gravity of the receiving platform on the construction platform.

[0045] The connecting part 2 includes a supporting part 201, a hanging part 202 and a hanging part 203. One end of the supporting part 201 is connected to the counterweight part 1, and the other end is connected to the hanging part 202, and the end of the hanging part 202 away from the supporting part 201 is connected to the hanging part 203. When in working state, Figure 3 As shown, the support member 201 supports the suspension member 202 to keep it away from the tabletop of the construction platform, and the hanging member 203 is suspended outside the construction platform through the hanging member 202. The hanging member 203 extends vertically downward, and a receiving portion 3 is fixed on one end away from the hanging member 202, so that the receiving portion 3 can be used to support the fallen and splashed welding slag.

[0046] like Figure 3 As shown, when the suspension 202 is away from the construction platform, a construction space A is formed between it and the construction platform for construction workers to perform welding work. The space can accommodate construction workers and construction objects. In this embodiment, the construction object is exposed steel bars.

[0047] Preferably, if Figure 1~2 As shown, the suspension 202 includes two sections, namely a first suspension 202-1 and a second suspension 202-2, which are connected by an adjustment member 202-3, and the adjustment member 202-3 can be a slide rail, a pulley assembly member, a telescopic arm structure, etc. The first suspension 202-1 is connected to the support member 201, and the second suspension 202-2 is connected to the hanging member 203.

[0048] By changing the positional relationship between the first suspension 202 - 1 and the second suspension 202 - 2 , the overall shape and / or size of the suspension 202 can be changed, thereby adjusting the positional relationship between the counterweight portion 1 and the receiving portion 3 .

[0049] More preferably, if Figure 2 As shown, the adjusting member 202-3 is a foldable hinge structure and the opening α of the foldable hinge structure faces downward. Since the first suspension 202-1 is connected to the counterweight part 1 through the support member 201, the second suspension 202-2 usually rotates around the foldable hinge structure. When the opening α faces downward, when the second suspension 202-2 rotates, it will always pass through the top space of the suspension 202, thereby driving the receiving part 3 to always pass through the top space of the suspension 202 without involving the construction space. Therefore, during the folding process of the receiving platform, the receiving part 3 does not contact the welding object.

[0050] When the first suspension 202-1 and the second suspension 202-2 are fitted together so that the suspension 202 is folded as a whole, the receiving part 3 will move to the space at the top of the counterweight part 1. At this time, the overall occupied space of the receiving platform is reduced, achieving a folding effect and being in a storage state; when the suspension 202 is unfolded again, the receiving platform returns to the working state.

[0051] Preferably, if Figure 1 As shown, the receiving portion 3 includes a receiving chassis and a receiving fence 301. The receiving fence 301 is arranged around the receiving chassis, and the whole constitutes a receiving space for receiving welding slag.

[0052] Preferably, if Figure 1 As shown, the counterweight part 1 includes a bearing plate 101 and a movable counterweight block 102. When the receiving platform is in working state, the bearing plate 101 supports the movable counterweight block 102 so that the center of gravity of the receiving platform is always placed on the construction platform.

[0053] Preferably, the bearing surface of the load-bearing plate 101 is provided with anti-slip textures.

[0054] Preferably, if Figure 1 As shown, the receiving part 3 includes a receiving protection plate 302. When the receiving platform is in working state, the receiving protection plate 302 is placed on one side of the receiving part 3 away from the edge of the construction platform to block splashing welding slag.

[0055] Preferably, if Figure 1 As shown, reinforcing ribs 204 are provided between the support member 201 and the suspension member 202, which enhance the support capability of the support member 201 to the suspension member 202. Overall, the load-bearing capacity of the receiving portion 3 is improved, so that more welding slag can be received and carried.

[0056] Embodiment 2:

[0057] The difference between this embodiment and embodiment 1 is that Figure 1 As shown, four universal wheels 103 are arranged at the bottom of the counterweight part 1. In this embodiment, the bottom of the counterweight part 1 is a rectangular structure, so the four universal wheels 103 are respectively arranged at the four corners of the bottom of the counterweight part 1. A locking device is arranged on each universal wheel 103, which can lock the universal wheel 103 and prohibit it from rotating.

[0058] Embodiment 3:

[0059] The difference between this embodiment and embodiments 1 and 2 is that Figure 1 As shown, in this embodiment, the counterweight part 1 further includes a warning plate 4, and a warning sign is arranged on the warning plate 4.

[0060] Finally, it should be noted that the above implementation cases are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the above implementation cases, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above implementation cases, or replace some of the technical features therein with equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the implementation cases of the utility model.
